entire prospectus carefully.
 
                           ONYX SOFTWARE CORPORATION
 
  ONYX is a leading provider of Enterprise Relationship Management ("ERM")
software solutions, which automate the key functions that enable enterprises to
more effectively acquire, manage and retain customers, partners and other
relationships. The ONYX ERM solution is based on the Microsoft Windows NT and
Microsoft BackOffice platforms and features a common data model which creates a
single repository of marketing, sales and service information that is
accessible throughout the enterprise. We designed our solution from inception
to be an integrated, enterprise-wide ERM solution that is easy to use through a
variety of interfaces, including the Internet and corporate intranets and
extranets. The ONYX ERM solution is rapidly deployable, scaleable, flexible and
reliable, resulting in a low total cost of ownership.
 
  We believe there is a market opportunity for an ERM system that employs
recent technology developments to enable enterprises to better address the
competitive and operational processes of today's challenging and rapidly
developing business environment to more effectively acquire, manage and retain
customers, partners and other relationships. This solution would provide a high
return on investment by improving the effectiveness of sales, marketing and
support activities while maintaining a low total cost of ownership.
 
  Our integrated product family allows enterprises to automate the customer
lifecycle across the entire enterprise, instead of automating only individual
departments. We target mid- to large-sized organizations and divisions of
Fortune 500 companies, marketing and selling our software and services through
a direct sales force, as well as through distributors. We have direct sales
offices in the United States, the United Kingdom, Singapore and Australia and
distributors in Latin America, Asia and Europe. We serve over 300 customers in
a variety of industries, including financial services, high technology, health
care, manufacturing and telecommunications. Our customers include American
Express Financial Advisors, Brooklyn Union Gas Company, Cincinnati Bell
Telephone, Datastream Systems Inc., GIGA Information Group, NTL Internet and
Sierra Health Services, Inc.
 
  Our principal executive offices are located at 310 - 120th Avenue N.E.,
Bellevue, Washington 98005 and our telephone number is (425) 451-8060. We were
incorporated in Washington in 1994.

                                  RISK FACTORS
 
  You should carefully consider the risks described below before buying shares
in this offering. The risks and uncertainties described below are not the only
ones we face. Additional risks and uncertainties not presently known to us or
that we currently deem immaterial also may impair our business operations.
 
  If any of the following risks actually occur, our business, financial
condition and operating results could be materially adversely affected, the
trading price of our common stock could decline, and you might lose all or part
of your investment.
 
  This prospectus contains forward-looking statements that involve risks and
uncertainties. We use words such as "anticipate," "believes," "expects,"
"future," and "intends," and similar expressions to identify forward-looking
statements. You should not place undue reliance on these forward-looking
statements, which apply only as of the date of this prospectus. Our actual
results could differ materially from those anticipated in these forward-looking
statements for many reasons, including the risks described below and elsewhere
in this prospectus.
 
OUR FUTURE OPERATING RESULTS ARE UNCERTAIN AND LIKELY TO FLUCTUATE.
 
  Our operating results have varied widely in the past, and we expect that they
will continue to fluctuate in the future. In addition, our operating results
may not follow any past trends. In particular, it is difficult to predict the
timing or amount of our license revenues because
 
  .  our sales cycles are lengthy and variable, typically ranging between two
     to six months from our initial contact with a potential customer to the
     signing of a license agreement (although occasionally sales require
     substantially more time);
 
  .  the amount of unfulfilled orders for our products at the beginning of a
     quarter is small because our products are typically shipped shortly
     after orders are received; and
 
  .  we recognize a substantial portion of our license revenues in the last
     month of a quarter, and often in the last weeks or days of a quarter.
 
  Nevertheless, we base our decisions regarding our operating expenses on
anticipated revenue trends. Because many of our expenses are relatively fixed,
a delay in recognizing revenue from a limited number of license transactions
could cause our operating results to vary significantly from quarter to quarter
and could result in operating losses. To the extent these expenses are not
followed by increased revenues, our operating results will suffer. Our future
operating results will depend on many factors, including
 
  .  demand for our products and services;
 
  .  product and price competition;
 
  .  variability in the mix of our license and service revenues;
 
  .  variability in the mix of our direct and indirect license revenues;
 
  .  variability in the mix of services that we perform and those performed
     by third-party service providers;
 
  .  success in expanding our direct sales force, indirect distribution
     channels and consulting organization;
 
  .  our ability to develop and market new and enhanced products on a timely
     basis;
 
  .  timing of our new product introductions and product enhancements or
     those of our competitors;
 
  .  continued purchases by our existing customers, including additional
     license and maintenance revenues;
 
  .  international sales and strategic acquisitions; and
 
  .  the loss of any key employees and timing of our new hires.

  We continue to experience significant seasonality with respect to software
license revenues. In recent years, we have recognized more license revenues in
our fourth quarter than in each of the first three quarters of a fiscal year
and have experienced lower license revenues in our succeeding first quarter. We
believe that these fluctuations are primarily caused by customer buying
patterns (often influenced by year-end budgetary pressures) and the efforts of
our direct sales force to meet or exceed year-end sales quotas. We expect that
seasonal trends will continue in the future.
 
  In the past, the software industry has experienced significant downturns,
particularly when general economic conditions decline and spending on
management information systems decreases. Our business, financial condition and
operating results may fluctuate substantially from quarter to quarter as a
consequence of general economic conditions in the software industry. In
addition, the fiscal or quarterly budget cycles of our customers can cause our
revenues to fluctuate from quarter to quarter. As a result of all of these
factors, 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. Fluctuations in our operating results, particularly
compared to the expectations of market analysts or investors, could cause
volatility in the price of our common stock. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business--Sales
and Marketing."
 
WE HAVE A LIMITED OPERATING HISTORY AND HAVE INCURRED LOSSES.
 
  We commenced operations in February 1994 and commercially released version
1.0 of ONYX Customer Center in December 1994. Accordingly, we have a limited
operating history, and we face all of the risks and uncertainties encountered
by early stage companies. The new and evolving nature of the ERM market
increases these risks and uncertainties. To address these risks, we must, among
other things
 
  .  successfully implement our sales and marketing strategy;
 
  .  respond to competitive developments;
 
  .  attract, retain and motivate qualified personnel;
 
  .  develop and upgrade our products and technologies more rapidly than our
     competitors; and
 
  .  commercialize our products and services incorporating these enhanced
     technologies.
 
  We incurred net losses in each quarter from ONYX's inception through the
third quarter of 1994 and from the first quarter of 1997 to the third quarter
of 1998. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations--Overview." As of September 30, 1998, we had an
accumulated deficit of $6.1 million. We expect to continue to devote
substantial resources to our product development and sales and customer
support. As a result, we will need to generate significant quarterly revenues
to achieve and maintain profitability. Our limited operating history makes it
difficult to forecast our future operating results. Our business strategies may
not be successful, and we may not be profitable in any future period. See
"Selected Consolidated Financial Data" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
OUR MARKET IS HIGHLY COMPETITIVE.
 
  The market for ERM software is intensely competitive, fragmented and rapidly
changing. We face competition in the ERM software market primarily from (1)
front-office software applications vendors, such as Clarify, Inc., Pivotal
Corp., SalesLogix Corporation, Siebel Systems, Inc. and The Vantive
Corporation, (2) large enterprise software vendors, particularly enterprise
resource planning ("ERP") system vendors, such as Baan Company N.V., J. D.
Edwards & Company, Oracle Corporation, PeopleSoft Corporation and SAP AG, and
(3) our potential customers' internal information technology ("IT")
departments, which may seek to develop proprietary ERM systems. In addition, as
we develop new products, particularly applications focused on particular
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 that may enable them to
rapidly increase their market share.
 
                                       6
<PAGE>
 
  Many of our competitors have already established supplier relationships with
divisions of our current or potential customers. These competitors may be able
to use their existing relationships to discourage these customers from
purchasing additional ONYX products or persuade them to replace our products
with their products. Many of our competitors have longer operating histories,
significantly greater resources and name recognition and a larger installed
base of customers. As a result, these competitors may have greater credibility
with our existing and potential customers. They also may be able to devote
greater resources to the development, promotion and sale of their products,
which would allow them to respond more quickly to new or emerging technologies
and changes in customer requirements.
 
  We expect that competition will increase as other established and emerging
companies enter the ERM market, as new products and technologies are introduced
and as new competitors enter the market. Increased competition may result in
price reductions, lower gross margins and loss of our market share, any of
which could materially adversely affect our business, financial condition and
operating results. See "Business--Competition."
 
WE DEPEND ON CONTINUED ADOPTION OF THE WINDOWS NT/MICROSOFT BACKOFFICE
PLATFORMS.
 
  We have designed our products to operate exclusively on the Windows NT and
Microsoft BackOffice platforms. As a result, we market our products exclusively
to customers who have developed their enterprise computing systems around these
platforms. Our future financial performance will depend on continued growth in
the number of enterprises that successfully adopt the Windows NT and Microsoft
BackOffice computing platforms. Acceptance of the Windows NT and Microsoft
BackOffice platforms may not continue to increase in the future. The adoption
of new operating systems and computing platforms, and the market for software
applications that run on those platforms, has in the past been significantly
affected by the timing of new product releases and enhancements to these
platforms. If the Windows NT/Microsoft BackOffice market fails to grow or grows
more slowly than we currently expect, or the market is affected by delays in
the release of new or enhanced products, our business, financial condition and
operating results could be materially adversely affected. Also, the performance
of our products depends, to some extent, on the technical capabilities of the
Windows NT and Microsoft BackOffice platforms. If the Windows NT and Microsoft
BackOffice platforms do not meet the technical demands of our products, the
performance or scalability of the ONYX ERM solution may be limited and, as a
result, our business, financial condition and operating results could be
materially adversely affected. See "Business--Industry Background," "--Products
and Services" and "--Competition."
 
THE MARKET FOR ERM SOLUTIONS IS NEW AND HIGHLY UNCERTAIN.
 
  The market for ERM products is still emerging, and continued growth in demand
for and acceptance of ERM products remains uncertain. Even if the ERM market
grows, businesses may purchase our competitors' ERM products or develop their
own. We believe that many of our potential customers are not fully aware of the
benefits of ERM solutions and that these solutions may never achieve market
acceptance. We have spent, and will continue to spend, considerable resources
educating potential customers about our products and ERM software solutions in
general. However, even with these educational efforts, market acceptance of our
products may not increase. If the market for our products does not grow or
grows more slowly than we currently anticipate, our business, financial
condition and operating results would be materially adversely affected.
 
WE RELY ON SALES OF ONLY ONE PRODUCT FAMILY.
 
  As of September 30, 1998, substantially all of our 1998 revenues were
generated from the sale of the ONYX Customer Center product family and related
maintenance, training and implementation services. We expect revenues from the
ONYX Customer Center product family to continue to account for a substantial
majority of our future revenues. As a result, factors adversely affecting the
pricing of or demand for the ONYX Customer Center product family, such as
competition or technological change, could materially adversely affect our
business, financial condition and operating results. Our future financial
performance will substantially depend on successfully deploying current
versions of the ONYX Customer Center product family and
 
                                       7
<PAGE>
 
developing, introducing and establishing customer acceptance of new and
enhanced versions of the ONYX Customer Center product family. See "Business--
Products and Services" and "--Sales and Marketing."
 
WE MAY BE UNABLE TO EXPAND OUR SALES AND SUPPORT INFRASTRUCTURE.
 
  To date, we have sold our products primarily through our direct sales force
and have supported our customers with our consulting and customer support
staff. Our future revenue growth will depend in large part on recruiting and
training additional direct sales, consulting and customer support personnel and
expanding our indirect distribution channels. We have experienced and continue
to experience difficulty in recruiting qualified sales and support personnel
and in establishing third-party relationships. We may not be able to
successfully expand our direct sales force or other distribution channels and
any such expansion may not result in increased revenues. We believe the
complexity of our products and the large-scale deployments anticipated by our
customers will require us to hire a number of highly trained consulting and
customer support personnel, and, if we are unable to do so, we may be unable to
meet customer demands. Our business, financial condition and operating results
would be materially adversely affected if we fail to expand our direct sales
force or other distribution channels or if we fail to expand our technical and
customer support staff. See "--We may experience difficulties managing our
growth, and we depend on certain key employees" and "Business--Strategy," "--
Sales and Marketing" and "--Customers and Markets."
 
WE MAY EXPERIENCE DIFFICULTIES MANAGING OUR GROWTH, AND WE DEPEND ON CERTAIN
KEY EMPLOYEES.
 
  Continued growth of our business may place a significant strain on our
existing management systems and resources. To compete effectively and manage
future growth, we must continue to improve our financial and management
controls, reporting systems and procedures on a timely basis and expand, train
and manage our work force. If we are not successful, our business, financial
condition and operating results would be materially adversely affected. Our
future performance will also largely depend on the efforts and abilities of our
key technical, customer support, sales and managerial personnel and our ability
to retain them. We have in the past experienced difficulty in hiring qualified
technical, customer support, sales and managerial personnel. In addition, the
loss of any of our executive officers could materially adversely affect our
business, financial condition and operating results. Our success will depend on
our ability to attract and retain such personnel in the future. See "--We may
be unable to expand our sales and support infrastructure," "Business--Sales and
Marketing" and "Management."
 
OUR MARKET IS SUBJECT TO RAPID TECHNOLOGICAL CHANGE.
 
  The software market in which we compete is characterized by rapid
technological change, frequent new product introductions, changes in customer
demands and evolving industry standards. For example, existing products can
become obsolete and unmarketable when products using new technologies are
introduced and new industry standards emerge. As a result, the life cycles of
our products are difficult to estimate. We may need to modify our products when
third parties change software that we integrate into our products. To be
successful, we must continue to enhance our current product line and develop
new products that successfully respond to such developments. For example, we
intend to enhance our products to provide more advanced Internet functionality,
which partially depends on available Internet security, bandwidth and
reliability. We have delayed enhancements or new product release dates several
times in the past and may not be able to introduce enhancements or new products
successfully or in a timely manner in the future. Our business, financial
condition and operating results would be materially adversely affected if we
delay release of our products and product enhancements or if these products and
product enhancements fail to achieve market acceptance when released. In
addition, customers may defer or forego purchases of our products if we, our
competitors or major hardware, systems or software vendors introduce or
announce new products or product enhancements. Such events could materially
adversely affect our business, financial condition and operating results. See
"Business--Products and Services."

WE FACE RISKS FROM EXPANSION OF OUR INTERNATIONAL OPERATIONS.
 
  We intend to continue to substantially expand our international operations
and enter new international markets. This expansion will require significant
management attention and financial resources to successfully translate and
localize our software products to various languages and to develop direct and
indirect international sales and support channels. We may not be able to
maintain or increase international market demand for the ONYX Customer Center
product family and if we are unable to do so, international sales will be
limited, and our business, financial condition and operating results will be
materially adversely affected. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
  International operations are subject to inherent risks, including
 
  .  the difficulties and costs of staffing and managing foreign operations;
 
  .  the difficulties of achieving the optimal mix of direct and indirect
     sales channels;
 
  .  the impact of possible adverse economic conditions;
 
  .  the costs of localizing products for foreign markets;
 
  .  longer receivables collection periods and greater difficulty in accounts
     receivable collection as compared to those experienced in our domestic
     operations;
 
  .  unexpected changes in regulatory requirements;
 
  .  reduced protection for intellectual property rights in some countries;
 
  .  fluctuations in the value of the U.S. dollar relative to other
     currencies;
 
  .  potentially adverse tax consequences;
 
  .  seasonal reductions in business activities; and
 
  .  political and economic instability.
 
  We (or our distributors or resellers) may not be able to sustain or increase
international revenues from licenses or from consulting and customer support.
The above factors could materially adversely affect our future international
revenues and, consequently, our business, financial condition and operating
results. Our foreign subsidiaries operate primarily in local currencies, and
their results are translated into U.S. dollars. We do not currently engage in
currency hedging activities, but we may do so in the future. Increases in the
value of the U.S. dollar relative to foreign currencies would materially
adversely affect our operating results. These factors could materially
adversely affect our future international operations and, consequently, our
business, financial condition and operating results. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business--Customers and Markets" and "--Sales and Marketing."
 
WE RELY HEAVILY ON KEY PARTNERS AND SYSTEMS INTEGRATORS.
 
  We have established relationships with a number of organizations that are
important to our worldwide sales, marketing and support activities and the
implementation of our products. We expect our relationships with these
organizations to provide marketing and sales opportunities for our direct sales
force and expand the distribution of our products. We believe that these
relationships help us keep pace with the technological and marketing
developments of major software vendors and, in certain instances, provide us
with technical assistance for our product development efforts. If we fail to
maintain our existing relationships, or to establish new relationships, or if
our partners do not perform to our expectations, our business, financial
condition and operating results could be materially adversely affected.
 
  We rely on a number of systems consulting and integration firms to implement
our software, provide customer support services and endorse our products during
the competitive evaluation stage of the sales cycle. Although we seek to
maintain relationships with these service providers, many of them have similar,
and often more established, relationships with our competitors. Further, these
third parties, many of which have significantly greater resources than we have,
may in the future market software products that compete with ours
 
                                       9
<PAGE>
 
or reduce or discontinue their relationships with us or their support of our
products. See "Business--Products and Services." In addition, our business,
financial condition and operating results could be materially adversely
affected if
 
  .  we are unable to develop and retain effective, long-term relationships
     with our systems integrators;
 
  .  we are unable to adequately train a sufficient number of systems
     integrators;
 
  .  our systems integrators do not have or do not devote the resources
     necessary to facilitate implementation of our products; or
 
  .  our systems integrators endorse a product or technology other than ours.
 
OUR SALES CYCLE IS LONG.
 
  We believe that an enterprise's decision to purchase an ERM system is
discretionary, involves a significant commitment of its resources and is
influenced by its budget cycles. To successfully sell our products, we
generally must educate our potential customers regarding the use and benefit of
our products, which can require significant time and resources. Consequently,
the period between initial contact and the purchase of our products is often
long and subject to delays associated with the lengthy budgeting, approval and
competitive evaluation processes that typically accompany significant capital
expenditures. Our sales cycles are lengthy and variable, typically ranging
between two to six months from our initial contact to the signing of a license
agreement (although occasionally sales require substantially more time). Such
delays may cause our operating results to vary widely. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business--Sales and Marketing."
 
WE DEPEND ON SERVICE REVENUES.
 
   Support and service revenues represented 24% of our total revenues for 1995,
30% for 1996, 32% for 1997 and 37% for the nine months ended September 30,
1998. We anticipate that service revenues will continue to represent a
significant percentage of total revenues. Because service revenues have a lower
gross margin than license revenues, a continued increase in the percentage of
total revenues represented by service revenues or an unexpected decrease in
license revenues could have a detrimental impact on overall gross margins and
our operating results. Service revenues depend in part on the ongoing renewals
of customer support contracts by our installed customer base, and we cannot
provide any assurances that these customers will renew their support contracts.
Also, we subcontract certain consulting, customer support and training services
to third-party service providers. Contract revenues generally carry lower gross
margins than our service business overall; as a result, our service revenues
and related margins may vary from period to period, depending on the mix of
these third-party contract revenues. In addition, consulting revenues as a
percentage of total revenues could decline if customers select third-party
service providers to install and service our products more frequently than they
have in the past. If service revenues are lower than anticipated, our business,
financial condition and operating results could be materially adversely
affected. Our ability to increase service revenues will depend in large part on
our ability to increase the scale of our services organization, including our
ability to successfully recruit and train a sufficient number of qualified
services personnel. We cannot provide any assurance that we will be able to do
so. See "--We may experience difficulties managing our growth, and we depend on
certain key employees" and "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
WE RELY ON SOFTWARE LICENSED TO US BY THIRD PARTIES.
 
  We incorporate into our products certain software that is licensed to us by
third-party software developers. Although we believe there are other sources
for this licensed software, any significant interruption in the supply of any
of this licensed software could materially adversely affect our sales, unless
and until we can replace the functionality provided by this licensed software.
Because our products incorporate software developed and maintained by third
parties, we depend on such third parties' abilities to deliver and support
reliable products,
 
                                       10
<PAGE>
 
enhance their current products, develop new products on a timely and cost-
effective basis, and respond to emerging industry standards and other
technological changes. The third-party software currently offered in
conjunction with our products may become obsolete or incompatible with future
versions of our products. Our sales could be materially adversely affected if
we are unable to replace the functionality provided by that software. See
"Business--Products and Services."
 
WE MAY BE UNABLE TO ADEQUATELY PROTECT OUR PROPRIETARY RIGHTS.
 
  Our success depends in part on our ability to protect our proprietary rights.
To protect our proprietary rights, we rely primarily on a combination of
copyright, trade secret and trademark laws, confidentiality agreements with
employees and third parties, and protective contractual provisions such as
those contained in license agreements with consultants, vendors and customers,
although we have not signed such agreements in every case. Despite our efforts
to protect our proprietary rights, unauthorized parties may copy aspects of our
products and obtain and use information that we regard as proprietary. Other
parties may breach confidentiality agreements and other protective contracts we
have entered into, and we may not become aware of, or have adequate remedies in
the event of, such breach.
 
  We pursue the registration of certain of our trademarks and service marks in
the United States and in certain other countries, but we have not secured
registration of all our marks. In addition, the laws of some foreign countries
do not protect our proprietary rights to the same extent as do the laws of the
United States, and effective copyright, trademark and trade secret protection
may not be available in other jurisdictions. A significant portion of our marks
include the word "Onyx." Other companies use "Onyx" in their marks alone or in
combination with other words, and we cannot prevent all third-party uses of the
word "Onyx." We license certain proprietary rights to third parties. Such
licensees may not abide by compliance and quality control guidelines with
respect to such proprietary rights and may take actions that would materially
adversely affect our business, financial condition and operating results.
 
  We have been subject to claims and expect to be subject to legal proceedings
and claims from time to time in the ordinary course of our business, including
claims of alleged infringement of trademarks and other intellectual property
rights of third parties. See "Business--Legal Proceedings." ONYX Computers,
Incorporated ("OCI") has filed a lawsuit against us alleging trademark
infringement of the mark ONYX in Canada. We are negotiating to settle the
litigation. However, our negotiations may not be successful. An adverse outcome
could have a material adverse effect on our financial condition and operating
results.
 
  In the computer software market, there is frequent and substantial
intellectual property litigation, which is often complex and expensive, and
involves a significant diversion of resources and uncertainty of outcome. We
may need to litigate to enforce and protect our intellectual property or to
defend against a claim of infringement or invalidity. Although we attempt to
avoid infringing known proprietary rights of third parties in our product
development efforts, we have been and expect to continue to be subject to legal
proceedings and claims from time to time in the ordinary course of our
business, including claims of alleged infringement of third-party proprietary
rights by us and our licensees. In addition, we expect that software developers
will be increasingly subject to infringement claims as the number of products
and competitors in our industry grows and the functionality of products in
different industry segments overlaps. Furthermore, former employers of our
present and future employees may assert claims that our employees have
improperly disclosed confidential or proprietary information to us. If we
discover that any elements of the ONYX Customer Center product family violate
third-party proprietary rights, we may be unable to obtain licenses on
commercially reasonable terms, if at all, and to avoid or settle litigation
without substantial expense and damage awards. Any claims relating to the
infringement of third-party proprietary rights, even if not meritorious, could
result in costly litigation, divert management's attention and resources, cause
product shipment delays or require us to pay damages or enter into royalty or
license agreements on terms that are not advantageous to us. Any of these
results could materially adversely affect our business, financial condition and
operating results.
 
                                       11
<PAGE>
 
  We rely on certain technology that we license from third parties, including
software that is integrated with internally developed software and used in our
products, to perform key functions. Although we are generally indemnified
against claims that such third-party technology infringes the proprietary
rights of others, such indemnification is not always available for all types of
intellectual property rights, and in some cases the scope of such
indemnification is limited. Even if we receive broad indemnification, third-
party indemnitors are not always well capitalized and may not be able to
indemnify us in the event of infringement, resulting in substantial exposure to
us. Infringement or invalidity claims arising from the incorporation of third-
party technology, and claims for indemnification from our customers resulting
from such claims, may be asserted or prosecuted against us. 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, and could materially adversely affect our business, financial
condition and operating results. See "Business--Intellectual Property and Other
Proprietary Rights."
 
OUR PRODUCTS MAY SUFFER FROM DEFECTS OR ERRORS.
 
  Software products as complex as ours 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 products until software
problems were corrected, and in some cases have provided product enhancements
to correct errors in released products. Our new products or releases may not be
free from errors after commercial shipments have begun. Any errors that are
discovered after commercial release could result in loss of revenues or delay
in market acceptance, diversion of development resources, damage to our
reputation or increased service and warranty costs, all of which could
materially adversely affect our business, financial condition and operating
results.
 
WE MAY FACE PRODUCT LIABILITY CLAIMS.
 
  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 products entails the risk of such
claims, and we may be subject to such claims in the future. Although we
maintain product liability insurance, this coverage may not be adequate and may
not continue to be available. Product liability insurance is expensive and in
the future may not be available on acceptable terms, if at all. A successful
product liability claim brought against us could materially adversely affect
our business, financial condition and operating results.
 
THE INTEGRATION OF ENCYC MAY BE DIFFICULT AND DISRUPTIVE.
 
  In September 1998, we acquired EnCyc, Inc, a privately held marketing
encyclopedia software company ("EnCyc"). We are currently in the process of
integrating the EnCyc business with our business. This integration is subject
to risks commonly encountered in making acquisitions, including, among others,
risk of loss of key personnel, difficulties associated with assimilating the
technologies, products, personnel and operations, potential disruption of our
ongoing business, and the ability of our sales force, consultants and
development staff to adapt to the new product line. We may not successfully
overcome these risks or any other problems encountered in connection with the
acquisition of EnCyc.
 
ANY FUTURE ACQUISITIONS MAY BE DIFFICULT AND DISRUPTIVE.
 
  As part of our business strategy, we expect to consider acquiring other
companies that would complement our existing product offerings, augment our
market coverage, enhance our technological capabilities, or otherwise offer us
growth opportunities. Future acquisitions may result in the following, any of
which could adversely affect our operating results or the trading price of our
common stock:
 
  .  issuances of equity securities that may dilute your ownership interest
     in ONYX;
 
  .  cash payments or assumption of debt or other liabilities of the
     companies we acquire;
 
                                       12
<PAGE>
 
  .  large one-time write-offs and amortization expenses related to goodwill
     and other intangible assets; and
 
  .  negative changes to our financial model.
 
  In addition, acquisitions involve many risks and challenges that we might not
successfully overcome, including
 
  .  difficulties in assimilating technologies, products, personnel and
     operations;
 
  .  diversion of management's attention;
 
  .  risks of entering markets in which we have no or limited prior
     experience; and
 
  .  loss of key employees of acquired organizations.
 
  We may not be able to successfully integrate any technologies, products,
personnel or operations of companies that we may acquire in the future. If we
fail to do so, our business, financial condition and operating results could be
materially adversely affected. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations."
 
OUR STOCK PRICE MAY BE VOLATILE.
 
  Prior to this offering, there has been no public market for our common stock.
The initial public offering price of our common stock will be determined
through negotiations between ONYX and the representatives of the Underwriters.
The market price for our shares of common stock is likely to be very volatile,
and, if you decide to purchase our shares, you may not be able to resell your
shares at or above the initial public offering price due to a number of
factors, including
 
  .  actual or anticipated variations in quarterly operating results;
 
  .  the gain or loss of significant orders;
 
  .  changes in earning estimates by analysts;
 
  .  announcements of technological innovations or new products by us or our
     competitors;
 
  .  general conditions in the software and computer industries; and
 
  .  other events or factors that negatively affect the stock market.
 
  In addition, the stock market in general has experienced extreme price and
volume fluctuations that have affected the market price for many companies in
industries similar or related to ours and that have been unrelated to these
companies' operating performances. These broad market fluctuations could
materially adversely affect the market price of our common stock.
 
CERTAIN EXISTING SHAREHOLDERS OWN A LARGE PERCENTAGE OF OUR VOTING STOCK.
 
  Following the closing of this offering, our officers, directors and
affiliated entities together will beneficially own approximately  % of the
outstanding shares of our common stock ( % if the Underwriters' over-allotment
option is exercised in full). As a result, these shareholders will be able to
control all matters requiring shareholder approval and, thereby, our management
and affairs. Matters that typically require shareholder approval include:
 
  .  election of directors;
 
  .  merger or consolidation; and
 
  .  sale of all or substantially all our assets.
 
  This concentration of ownership may delay, deter or prevent acts that would
result in a change of control, which in turn could reduce the market price of
our common stock. See "Principal Shareholders."

OUR ARTICLES OF INCORPORATION AND BYLAWS AND WASHINGTON LAW CONTAIN PROVISIONS
THAT COULD DISCOURAGE A TAKEOVER.
 
  Certain provisions of our Restated Articles and our Amended and Restated
Bylaws (the "Restated Bylaws") and Washington law could make it more difficult
for a third party to obtain control of ONYX. See "Description of Capital
Stock."
 
FUTURE SALES OF OUR COMMON STOCK MAY DEPRESS OUR STOCK PRICE.
 
  After this offering, we will have outstanding    shares of common stock.
Sales of a substantial number of shares of common stock in the public market
following this offering could materially adversely affect the market price of
our common stock. All the shares sold in this offering will be freely tradable.
The remaining 13,360,134 shares of common stock outstanding after this offering
will be available for sale in the public market as follows:

WE FACE "YEAR 2000" RISKS.
 
  Many currently installed computer systems are not capable of distinguishing
21st century dates from 20th century dates. As a result, beginning on January
1, 2000, computer systems and software used by many companies and organizations
in a wide variety of industries will produce erroneous results or fail unless
they have been modified or upgraded to process date information correctly.
Significant uncertainty exists in the software industry and other industries
concerning the scope and magnitude of problems associated with the century
change. Based on our assessment to date, we believe the current versions of our
software products are "Year 2000 compliant"--that is, they are capable of
adequately distinguishing 21st century dates from 20th century dates. However,
our products are generally integrated into enterprise systems involving
sophisticated hardware and complex software products that may not be Year 2000
compliant. We may face claims based on Year 2000 problems in other companies'
products, or issues arising from the integration of multiple products within an
overall system. We also need to ensure Year 2000 compliance of our own internal
computer systems. In addition, we may experience reduced sales of our products
as potential customers reduce their budgets for ERM software due to increased
expenditures on their own Year 2000 compliance efforts. We do not expect the
total cost to us of Year 2000 compliance issues to be material to our business,
financial condition and operating results. However, we and our customers and
suppliers may not identify and remediate all significant Year 2000 problems on
a timely basis. Remediation efforts may involve significant time and expense
and unremediated problems could materially adversely affect our business,
financial condition and operating results. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Year 2000
Compliance."
 
WE FACE RISKS RELATED TO THE EUROPEAN MONETARY CONVERSION.
 
  We are aware of the issues associated with the forthcoming changes in Europe
aimed at forming a European economic and monetary union (the "EMU"). One of the
changes resulting from this union will require EMU member states to irrevocably
fix their respective currencies to a new currency, the Euro, on January 1,
1999, at which date the Euro will become a functional legal currency of these
countries. During the
 
                                       14
<PAGE>
 
next three years, business in the EMU member states will be conducted in both
the existing national currency, such as the French Franc or the Deutsche Mark,
and the Euro. As a result, companies operating in or conducting business in EMU
member states will need to ensure that their financial and other software
systems are capable of processing transactions and properly handling these
currencies, including the Euro.
 
  We are still assessing the impact the conversion to the Euro will have on
both our internal systems and the products we sell. We will take appropriate
corrective actions based on the results of such assessment. We have not yet
determined the cost related to addressing this issue. This issue and its
related costs could materially adversely affect our business, financial
condition and operating results.
 
CHANGES IN ACCOUNTING STANDARDS COULD AFFECT OUR FUTURE OPERATING RESULTS.
 
  We recognize revenues from software license agreements upon delivery of our
software products if
 
  .  persuasive evidence of an arrangement exists;
 
  .  collection is probable;
 
  .  the fee is fixed or determinable; and
 
  .  vendor-specific objective evidence exists to allocate the total fee to
     all elements of the arrangement.
 
  We recognize customer support (maintenance) revenues ratably over the
contract term--typically one year--and recognize revenues for consulting and
training services as such services are performed.
 
  Statement of Position 97-2 ("SOP 97-2"), "Software Revenue Recognition," was
issued in October 1997 by the American Institute of Certified Public
Accountants and amended by Statement of Position 98-4 ("SOP 98-4"). We adopted
SOP 97-2 effective January 1, 1998. Based on our interpretation of SOP 97-2 and
SOP 98-4, we believe our current revenue recognition policies and practices are
consistent with SOP 97-2 and SOP 98-4. However, full implementation guidelines
for this standard have not yet been issued. Once available, such implementation
guidance could lead to unanticipated changes in our current revenues accounting
practices, which changes could materially adversely affect our business,
financial condition and operating results. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
  Additionally, the accounting standard setters, including the Securities and
Exchange Commission (the "Commission") and the Financial Accounting Standards
Board are reviewing the accounting standards related to business combinations
and stock-based compensation. Any changes to either of these standards or any
other accounting standards could materially adversely affect our business,
financial condition and operating results.

                                USE OF PROCEEDS
 
  We expect to receive approximately $  million in net proceeds from the sale
of the    shares of common stock in this offering, assuming the initial public
offering price is $  per share (approximately $  million if the Underwriters'
over-allotment option is exercised in full).
 
  We intend to use the net proceeds of this offering primarily for additional
working capital and other general corporate purposes, including increased
domestic and international sales and marketing expenditures, increased research
and development expenditures, and capital expenditures made in the ordinary
course of business. We may also use a portion of the net proceeds to acquire
additional businesses, products and technologies or to establish joint ventures
that we believe will complement our current or future business. However, we
have no specific plans, agreements or commitments, oral or written to do so,
and are not currently engaged in any negotiations for any such acquisition or
joint venture. The amounts that we actually expend for working capital purposes
will vary significantly depending on a number of factors, including future
revenue growth, if any, the amount of cash we generate from operations and the
progress of our product development efforts. As a result, we will retain broad
discretion in the allocation of the net proceeds of this offering. Pending the
uses described above, we will invest the net proceeds in short-term, interest-
bearing, investment-grade securities.
 
                                DIVIDEND POLICY
 
  We have never paid cash dividends on our common stock. 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
 
  If you invest in our common stock, your interest will be diluted to the
extent of the difference between the public offering price per share of our
common stock and the pro forma as adjusted net tangible book value per share of
our common stock after this offering. We calculate net tangible book value per
share by dividing the net tangible book value (total assets less intangible
assets and total liabilities) by the number of outstanding shares of common
stock.
 
  The pro forma net tangible book value of ONYX at September 30, 1998, after
giving effect to the automatic conversion of all outstanding shares of
redeemable convertible preferred stock into 3,533,925 shares of common stock
upon the closing of this offering was $2,974,000, or $0.22 per share of common
stock. After giving effect to the sale of the    shares of common stock at an
assumed initial public offering price of $  per share (less underwriting
discounts and commissions and estimated expenses we expect to pay in connection
with this offering), the pro forma as adjusted net tangible book value of ONYX
at September 30, 1998 would be $  million, or $  per share. This represents an
immediate increase in the as adjusted pro forma net tangible book value of $
per share to existing shareholders and an immediate dilution of $  per share to
new investors, or approximately  % of the assumed offering price of $  per
share.
 
  The following table illustrates this per share dilution:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  This section of this prospectus includes a number of forward-looking
statements that reflect our current views with respect to future events and
financial performance. We use words such as "anticipate," "believes,"
"expects," "future," and "intends," and similar expressions to identify
forward-looking statements. You should not place undue reliance on these
forward-looking statements, which apply only as of the date of this prospectus.
These forward-looking statements are subject to certain risks and uncertainties
that could cause actual results to differ materially from historical results or
our predictions. For a description of these risks, see "Risk Factors."
 
OVERVIEW
 
  ONYX is a leading provider of ERM software solutions, which automate the key
functions that enable enterprises to more effectively acquire, manage and
retain customers, partners and other relationships. ONYX was founded in
February 1994. We commercially released version 1.0 of our flagship product,
ONYX Customer Center, in December 1994. In our first year of operation, we
focused primarily on research and development activities. From early 1995
through mid-1996, we began to recruit personnel, purchase operating assets,
market our products, build a direct sales force and expand our service
business. Our revenues totaled $2.2 million in 1995 and $9.6 million in 1996.
We generated net income of $523,000 in 1995 and $1.4 million in 1996.
 
  In mid-1996, we substantially expanded our operations to capitalize on our
opportunity within the rapidly emerging ERM market. We decided, at the
potential expense of profitability, to accelerate our investments in research
and development, marketing, domestic and international sales channels,
professional services and our general and administrative infrastructure. Since
mid-1996, we have
 
  . hired more than 220 employees;
 
  . opened 13 domestic field sales offices;
 
  . entered the European and Pacific markets by opening direct sales offices
    in the United Kingdom, Australia and Singapore;
 
  . released localized versions of ONYX Customer Center in German, Spanish
    and International English;
 
  . established distributor relationships with 11 international resellers;
 
  . released two major upgrades to our flagship product;
 
  . released four Internet-based products; and
 
  . acquired a leading marketing encyclopedia software developer, EnCyc, Inc.
    ("EnCyc").
 
  We believe these investments have been critical to our growth to date. Our
revenues were $19.4 million in 1997, representing an increase of 102% from
1996. During the first nine months of fiscal 1998, our revenues were $24.0
million, representing an increase of 96% compared to the same period of 1997.
Nevertheless, these investments have also significantly increased our operating
expenses, contributing to the net losses that we incurred in each fiscal
quarter since the first quarter of 1997. As of September 30, 1998, we had an
accumulated deficit of $6.1 million. We anticipate that our operating expenses
will increase substantially for the foreseeable future as we expand our product
development, sales and marketing and professional services staff. Accordingly,
we may incur net losses in future quarters. See "Risk Factors--Our future
operating results are uncertain and likely to fluctuate" and "--We have a
limited operating history and have incurred losses."
 
 Source of Revenues and Revenue Recognition Policy
 
  We generate revenues from sales of software licenses and services. We receive
software license revenues from licensing our products directly to end-users and
indirectly through resellers. To a lesser extent, we receive software license
revenues from third-party products that we distribute. We receive service
revenues from sales
 
                                       21
<PAGE>
 
of post-contract support, consulting and training services that we perform for
customers that license our products either directly from us or indirectly
through resellers.
 
  We recognize revenues from software license agreements upon delivery of our
software products if there is persuasive evidence of an arrangement, collection
is probable, the fee is fixed or determinable, and there is sufficient vendor-
specific objective evidence to support allocating the total fee to all elements
of the arrangement. Elements included in multiple element arrangements could
consist of software products, upgrades, enhancements, customer support services
or consulting services. If an acceptance period is required, we recognize
revenues upon the earlier of customer acceptance or the expiration of the
acceptance period. We enter into reseller arrangements that typically provide
for sublicense fees payable to us based on a percentage of our list price. We
recognize sublicense fees as they are reported by the reseller when it
relicenses our products to end-users.
 
  We recognize revenues from customer support services ratably over the term of
the contract, typically one year. We derive consulting revenues primarily from
implementation services performed on a time-and-materials basis under separate
service arrangements related to the installation of our software products. We
recognize revenues from consulting and training services as these services are
performed. If a transaction includes both license and service elements, we
recognize license fee revenue on shipment of the software, provided services do
not include significant customization or modification of the base product, and
the payment terms for licenses are not subject to acceptance criteria. In cases
where license fee payments are contingent on the acceptance of services, we
defer recognition of revenues from both the license and the service elements
until the acceptance criteria are met.
 
  We believe that our current revenue recognition policies and practices are
materially consistent with the revenue recognition rules released by the
American Institute of Certified Public Accountants in October 1997 and in early
1998. However, full implementation guidelines for these rules have not yet been
issued. See "Risk Factors--Changes in accounting standards could affect our
future operating results."
 
 EnCyc Acquisition
 
  On September 14, 1998, we acquired EnCyc, a marketing encyclopedia software
developer founded in August 1995. In exchange for all the outstanding shares of
EnCyc, we issued 233,333 shares of our common stock, paid $500,000 to EnCyc
shareholders and liquidated $250,000 of EnCyc's existing long-term debt. In
addition, in connection with the acquisition, we issued options to EnCyc
employees to purchase up to 75,000 shares of our common stock. For accounting
purposes, these options have been treated as part of the purchase price,
resulting in a total purchase price of $2.3 million, including direct costs of
the acquisition. In determining the purchase price, we estimated the fair value
of our common stock and stock options issued in the transaction. We accounted
for the acquisition under the purchase method of accounting. We have included
the results of operations of EnCyc and the fair value of the assets acquired
and liabilities assumed in our Consolidated Financial Statements beginning on
the acquisition date. We recorded capitalized technology and other intangible
assets of $2.2 million that will be amortized on a straight-line basis over the
five years following the acquisition, which represents the expected life of the
intangible assets that we acquired.
 
RESULTS OF OPERATIONS
 
  We believe that period-to-period comparisons of our operating results are not
meaningful. You should not rely on them to predict our future performance. You
should consider our prospects in light of the risks, expenses and difficulties
frequently encountered by early stage companies, particularly companies in new
and rapidly evolving markets. However, we may not be able to successfully
address such risks and difficulties. In addition, although we have experienced
significant revenue growth recently, such revenue growth may not continue, and
we may not achieve or maintain profitability in the future. See "Risk Factors--
Our future operating results are uncertain and likely to fluctuate" and "--We
have a limited operating history and have incurred losses."

RESULTS OF OPERATIONS--NINE MONTHS ENDED SEPTEMBER 30, 1997 AND 1998
 
REVENUES
 
  Total revenues, which consist of software license and service revenues,
increased 96%, from $12.3 million for the nine months ended September 30, 1997
to $24.0 million for the nine months ended September 30, 1998. No single
customer accounted for more than 10% of our revenues for the nine months ended
September 30, 1997 or 1998.
 
  Our license revenues increased 80%, from $8.4 million for the nine months
ended September 30, 1997 to $15.2 million for the nine months ended September
30, 1998. The increase in license revenues resulted primarily from an increase
in the volume of shipments of our software applications due to increased market
acceptance of our products, repeat business in our existing customer base and
expansion in international markets.
 
  Our service revenues increased 129%, from $3.9 million for the nine months
ended September 30, 1997 to $8.9 million for the nine months ended September
30, 1998. Service revenues represented 32% of our total revenues for the nine
months ended September 30, 1997 and 37% for the nine months ended September 30,
1998. The increase in service revenues resulted primarily from an increase in
customer support revenues as our installed base continued to grow and, to a
lesser extent, increases in consulting and training services. We expect the
proportion of service revenues to total revenues to fluctuate in the future,
depending in part on our customers' direct use of third-party consulting and
implementation service providers and the ongoing renewals of customer support
contracts. See "Risk Factors--We depend on service revenues."
 
                                       23
<PAGE>
 
  Revenues outside of North America totaled $699,000 for the nine months ended
September 30, 1997 and $4.2 million for the nine months ended September 30,
1998. Revenues from indirect sales channels totaled $73,000 for the nine months
ended September 30, 1997 and $6.2 million for the nine months ended
September 30, 1998. The increase in both our international and indirect
revenues resulted primarily from the increased volume of business generated by
our international resellers, the majority of which were added in mid-1997.
 
  We do not believe that we can sustain the historical percentage growth rates
of license and service revenues as our revenue base increases.
 
COST OF REVENUES
 
 Cost of license revenues
 
  Cost of license revenues consists of license fees for third-party software,
product media, product duplication and manuals. Cost of license revenues
increased 574%, from $90,000 for the nine months ended September 30, 1997 to
$607,000 for the nine months ended September 30, 1998. Cost of license revenues
as a percentage of related license revenues was 1% for the nine months ended
September 30, 1997 and 4% for the nine months ended September 30, 1998. The
increase in dollar amount in cost of license revenues resulted primarily from
an increase in third-party products we resold, as well as an increase in the
volume of shipments of our software applications. The increase in cost of
license revenues as a percentage of related license revenues resulted primarily
from the increase in third-party products we sold, which contribute
significantly lower margins.
 
 Cost of service revenues
 
  Cost of service revenues consists of personnel and third-party service
provider costs related to consulting services, customer support and training.
Cost of service revenues increased 92%, from $3.1 million for the nine months
ended September 30, 1997 to $5.9 million for the nine months ended September
30, 1998. The increase in dollar amount resulted primarily from the hiring and
training of consulting, support and training personnel to support our growing
customer base. Cost of service revenues as a percentage of related service
revenues was 79% for the nine months ended September 30, 1997 and 66% for the
nine months ended September 30, 1998. The cost of services as a percentage of
service revenues may vary between periods primarily for two reasons: (1) the
mix of services we provide (consulting, customer support, training), which have
different cost structures, and (2) the resources we use to deliver these
services (internal versus third parties). The decrease in cost of service
revenues as a percentage of the related service revenues resulted from a lower
percentage use of third-party service providers, which contribute significantly
lower margins than internal resources, and increased customer support revenues,
which contribute higher margins than the other services.
 
COSTS AND EXPENSES
 
 Sales and marketing
 
  Sales and marketing expenses consist primarily of salaries, commissions and
bonuses earned by sales and marketing personnel, lead referral fees, travel and
promotional expenses and facility and communication costs for direct sales
offices. Sales and marketing expenses increased 87%, from $7.3 million for the
nine months ended September 30, 1997 to $13.6 million for the nine months ended
September 30, 1998. The increase in dollar amount of our sales and marketing
expenses resulted primarily from our continued investment in sales and
marketing infrastructure, both domestically and internationally, which included
significant personnel-related expenses, recruiting fees, travel expenses, and
related facility and equipment costs, as well as increased marketing
activities, including trade shows, public relations, direct mail campaigns and
other promotional expenses. The increase in dollar amount of our sales and
marketing expenses also resulted from an increase in lead referral fees made
under our agreement with certain international partners. Sales and marketing
expenses
 
                                       24
<PAGE>
 
represented 59% of our total revenues for the nine months ended September 30,
1997 and 57% for the nine months ended September 30, 1998. The decrease in
sales and marketing expenses as a percentage of total revenues reflects the
more rapid growth in our revenues compared to the growth of sales and marketing
expenses due to maturing direct and indirect sales channels, as well as
increased service revenues as a percentage of total revenues. We believe that
we need to significantly increase our sales and marketing efforts to expand our
market position and further increase acceptance of our products. Accordingly,
we anticipate that sales and marketing expenses will increase in future
periods.
 
 Research and development
 
  Research and development expenses consist primarily of salaries, benefits and
equipment for software developers, quality assurance personnel, program
managers and technical writers and payments to outside contractors. Research
and development expenses increased 129%, from $2.9 million for the nine months
ended September 30, 1997 to $6.7 million for the nine months ended September
30, 1998. The increase in dollar amount resulted from an increase in the number
of software developers and quality assurance personnel and the use of outside
contractors to support our product development and testing activities. Research
and development costs represented 24% of our total revenues for the nine months
ended September 30, 1997 and 28% for the nine months ended September 30, 1998.
The increase in research and development expenses as a percentage of total
revenues primarily reflects the more rapid investment in our research and
development activities compared to the growth of our revenues in this period.
We believe that we need to significantly increase our research and development
investment to expand our market position and continue to expand our product
line. Accordingly, we anticipate that research and development expenses will
increase in future periods.
 
 General and administrative
 
  General and administrative expenses consist primarily of salaries, benefits
and related costs for our executive, finance, administrative and information
services personnel, professional services fees. General and administrative
expenses increased 74%, from $1.5 million for the nine months ended September
30, 1997 to $2.6 million for the nine months ended September 30, 1998. The
increase in dollar amount resulted primarily from the addition of finance,
executive and administrative personnel to support the growth of our business.
General and administrative costs represented 12% of our total revenues for the
nine months ended September 30, 1997 and 11% for the nine months ended
September 30, 1998. We believe our general and administrative expenses will
continue to increase as we expand our administrative staff, domestically and
internationally, and incur expenses associated with becoming a public company,
including, but not limited to, annual and other public reporting costs,
directors' and officers' liability insurance, investor relations programs and
professional services fees.
 
 Deferred compensation
 
  We recorded deferred compensation of approximately $98,000 for the nine
months ended September 30, 1998, representing the difference between the
exercise prices of options granted to acquire 138,400 shares of common stock
during the nine months ended September 30, 1998 and the deemed fair value for
financial reporting purposes of our common stock on the grant dates. We
amortized deferred compensation expense of $77,000 during the nine months ended
September 30, 1998. Total deferred compensation at September 30, 1998 of
$161,000 will be amortized over the vesting periods of the options.
 
 Interest income, net
 
  Interest income, net consists of earnings on our cash and cash equivalent and
short-term investment balances offset by interest expense associated with debt
obligations. Interest income, net was $231,000 for the nine months ended
September 30, 1997 and $95,000 for the nine months ended September 30, 1998.
The decrease in interest income, net resulted from a reduction in interest
income as a result of declining cash and cash equivalents and short-term
investment balances.

 Income taxes
 
  As a result of our net operating loss in 1997 and prior years' profitability,
we realized a tax benefit of $606,000 for the nine months ended September 30,
1997. We recorded an income tax provision of $193,000 for the nine months ended
September 30, 1998 in connection with our foreign operations. We made no
provision or benefit for federal or state income taxes for the nine months
ended September 30, 1998 due to the operating losses incurred in the period. As
of September 30, 1998, we had net operating loss carryforwards for tax
reporting purposes of approximately $6.1 million, which begin to expire in
2017. In addition, as of September 30, 1998, we had tax credit carryforwards of
approximately $453,000, which begin to expire in 2017. The Internal Revenue
Code of 1986, as amended (the "Code"), limits the use in any future period of
net operating loss and credit carryforwards upon the occurrence of certain
events, including a significant change in ownership interests. We had net
deferred tax assets, including net operating loss carryforwards and tax
credits, totaling approximately $2.7 million as of September 30, 1998. We have
recorded a valuation allowance for the entire deferred tax asset as a result of
uncertainties regarding the realization of the asset balance. See Note 9 of
Notes to Consolidated Financial Statements.
 
RESULTS OF OPERATIONS--YEARS ENDED DECEMBER 31, 1995, 1996 AND 1997
 
REVENUES
 
  Total revenues increased 339%, from $2.2 million in 1995 to $9.6 million in
1996, and 102% to $19.4 million in 1997. During 1995, one customer accounted
for 15% of total revenues. No single customer accounted for more than 10% of
our revenues in 1996 or 1997.
 
  Our license revenues increased 308%, from $1.7 million in 1995 to $6.8
million in 1996, and 94% to $13.2 million in 1997. The increase in license
revenues from 1995 to 1996 primarily resulted from an increase in the volume of
shipments of our software applications due to increased market acceptance of
our existing products, new product offerings and, to a lesser extent, repeat
business from our existing customer base. The increase in revenues from 1996 to
1997 resulted from the continued effect of those same factors, as well as
expansion in international markets, primarily Europe and the South Pacific.
 
  Our service revenues increased 434%, from $533,000 in 1995 to $2.8 million in
1996, and 119% to $6.2 million in 1997. Of our total revenues, service revenues
represented 24% in 1995, 30% in 1996 and 32% in 1997. The increases in service
revenues from 1995 to 1997 resulted primarily from the increase in consulting,
customer support and training services associated with increased sales of our
software applications and overall growth of our installed base of customers
during these periods. See "Risk Factors--We depend on service revenues."
 
  Revenues outside of North America totaled $1,000 in 1995, $348,000 in 1996
and $1.2 million in 1997. The increases in international revenues from 1995 to
1997 resulted from our investment in direct and indirect sales channels,
primarily in Europe, Australia and Singapore, over the period. Prior to 1997,
revenues from indirect sales channels were insignificant. In 1997, revenues
from indirect sales channels totaled $103,000.
 
COST OF REVENUES
 
 Cost of license revenues
 
  Cost of license revenues increased 420%, from $10,000 in 1995 to $52,000 in
1996, and 381% to $250,000 in 1997. Cost of license revenues as a percentage of
related license revenues were 1% in 1995 and 1996 and 2% in 1997. The increases
in dollar amount of cost of license revenues from 1995 to 1997 resulted
primarily from an increase in the volume of shipments of our software
applications and product royalties for third-party technology shipped with our
Web Wizard and ONYX Customer Center-Unplugged products.
 
                                       26

 Cost of service revenues
 
  Cost of service revenues increased 587%, from $300,000 in 1995 to $2.1
million in 1996, and 144% to $5.0 million in 1997. The increases in dollar
amount from 1995 to 1997 resulted from the hiring and training of consulting,
support and training personnel to support our growing customer base and
increased use of third-party service providers. Cost of service revenues as a
percentage of related service revenues were 56% in 1995, 72% in 1996 and 80% in
1997. The increases in cost of service revenues as a percentage of related
service revenues from 1995 to 1997 primarily reflected a higher concentration
of third-party service providers, which results in significantly lower margins.
 
COSTS AND EXPENSES
 
 Sales and marketing
 
  Sales and marketing expenses increased 447%, from $583,000 in 1995 to $3.2
million in 1996, and 246% to $11.0 million in 1997. The increases in sales and
marketing expenses from 1995 to 1997 resulted primarily from our investment in
sales and marketing infrastructure, both domestically and internationally,
which included significant personnel-related expenses, recruiting fees, travel
expenses, and related facility and equipment costs, as well as increased
marketing activities, including trade shows, public relations, direct mail
campaigns and other promotional expenses. Sales and marketing expenses
represented 27% of our total revenues in 1995, 33% in 1996 and 57% in 1997. The
increases in sales and marketing expenses as a percentage of total revenues
from 1995 to 1997 primarily reflects the more rapid investment in our sales and
marketing infrastructure compared to the growth of our revenues in this period.
 
 Research and development
 
  Research and development expenses increased 359%, from $255,000 in 1995 to
$1.2 million in 1996, and 304% to $4.7 million in 1997. The increases in
research and development expenses from 1995 to 1997 primarily related to the
increase in the number of software developers and quality assurance personnel
and outside contractors brought on to support our product development and
testing activities. Research and development costs represented 12% of our total
revenues in 1995, 12% in 1996 and 24% in 1997. The increases in research and
development expenses as a percentage of total revenues from 1995 to 1997
primarily reflects the more rapid investment in our research and development
activities compared to the growth of our revenues in this period.
 
 General and administrative
 
  General and administrative expenses increased 345%, from $249,000 in 1995 to
$1.1 million in 1996, and 94% to $2.2 million in 1997. The increases from 1995
to 1997 primarily resulted from the addition of finance, executive and
administrative personnel to support the growth of our business during these
periods. General and administrative costs represented 11% of our total revenues
in each of 1995, 1996 and 1997.
 
 Deferred compensation
 
  We recorded deferred compensation of approximately $140,000 in December 1997,
representing the difference between the exercise prices of 405,450 shares of
common stock subject to options granted during December 1997 and the deemed
fair value for financial reporting purposes of our common stock on the grant
date. The deferred compensation will be amortized to operating expense over the
vesting periods of the options.
 
 Interest income, net
 
  Interest income, net was $10,000 in 1995, $118,000 in 1996 and $314,000 in
1997. The increases from 1995 to 1997 primarily resulted from increases in
interest income resulting from higher average cash and cash equivalent and
short-term investment balances over the period.
 
                                       27
<PAGE>
 
 Income taxes
 
  Our provision for federal, state and foreign income taxes was $288,000 for
1995 and $789,000 for 1996, yielding an effective rate of 36% in 1995 and 1996.
As a result of our net operating loss in 1997 and prior years' profitability,
we realized a tax benefit of $888,000 in 1997. See Note 9 of Notes to
Consolidated Financial Statements.

months ended September 30, 1998, generally apply to the comparison of results
of operations for the seven quarters in the 21-month period ended September 30,
1998, adjusted for the seasonality we have experienced as referred to below.
Cost of service revenues remained relatively flat in dollar amount during the
first three quarters of 1998 due to the declining use of third-party service
providers offset by the hiring of our own service personnel. Research and
development expenses declined in the three months ended September 30, 1998 due
to reduced use of independent contractors and other outside services used for
development of our products. The significant increase in sales and marketing
expenses during the three months ended September 30, 1998 resulted primarily
from increased lead referral fees made under our agreement with certain
international partners.
 
  Our quarterly operating results have varied widely in the past, and we expect
that they will continue to fluctuate in the future as a result of a number of
factors, many of which are outside our control. See "Risk Factors--Our future
operating results are uncertain and likely to fluctuate" and "--Changes in
accounting standards could affect our future revenues and earnings." We have in
the past experienced delays in the planned release dates of new software
products or upgrades, and we have discovered software defects in new products
after their introduction. New products or upgrades may not be released
according to schedule, or may contain defects when released. Either of these
situations could result in adverse publicity, loss of revenues, delay in market
acceptance or claims by customers brought against us, any of which could
materially adversely affect on our business, financial condition and operating
results. See "Risk Factors--Our market is subject to rapid technological
change," "--Our products may suffer from defects or errors" and "--Changes in
accounting standards could affect our future operating results." In addition,
the timing of individual sales has been difficult for us to predict, and large
individual sales have, in some cases, occurred in quarters subsequent to those
in which we originally anticipated they would occur. The loss or deferral of
one or more significant sales could materially adversely affect our quarterly
operating results. See "Risk Factors--Our sales cycle is long."

  ONYX has experienced, and expects to continue to experience, significant
seasonality with respect to software license revenues. In recent years, there
has been a greater demand for our products in our fourth quarter than in each
of the first three quarters of a fiscal year. For example, in 1997, 37% of
total revenues, 36% of license revenues and 38% of service revenues were
recognized in the fourth quarter. We also have experienced lower revenues in
our succeeding first quarter. For example, license revenues in the first
quarter of 1998 decreased 14% from the fourth quarter of 1997. We believe that
these fluctuations are caused by customer buying patterns (often influenced by
year-end budgetary pressures) and the efforts of our direct sales force to meet
or exceed year-end sales quotas. We expect that seasonal trends will continue
for the foreseeable future. See "Risk Factors--Our future operating results are
uncertain and likely to fluctuate."
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since our inception, we have primarily financed our operations through
private placements of our common and preferred stock. Through September 30,
1998, proceeds from private placements of common and preferred stock totaled
$11.3 million. To a lesser extent, we have financed our operations through
equipment financing and traditional financing arrangements.
 
  As of September 30, 1998, we had cash and cash equivalents of $177,000, a
decrease of $3.3 million from cash and cash equivalents held at December 31,
1997. In October 1998, we received a federal income tax refund of $963,000. Our
working capital at September 30, 1998 was $1.6 million, compared to $9.3
million at December 31, 1997. We have a working capital revolving line of
credit with a financial institution 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 $8.0 million. As of November 30, 1998, we had borrowed
$1.6 million under the facility. The facility expires in June 2000. 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 September 30, 1998 and,
at that time, there were no borrowings outstanding under this credit facility.
 
  We also have a $3.0 million term loan facility with a financial institution
for the purpose of financing new capital equipment purchases. This facility
operates as a revolver through August 1999, after which time any balances must
be paid over a 36-month term. This facility also requires us to maintain
certain financial covenants, including a requirement that we maintain certain
financial ratios. We were in compliance with these covenants at September 30,
1998 and, at that time, there were no borrowings outstanding under this credit
facility. As of November 30, 1998, we had borrowed $63,000 under this line of
credit.
 
  Our operating activities resulted in net cash inflows of $584,000 in 1995 and
$323,000 in 1996, and net cash outflows of $5.0 million in 1997 and $3.4
million for the nine months ended September 30, 1998. The sources of cash in
1995 and 1996 were primarily income from operations, increases in accounts
payable and accrued liabilities and increases in deferred revenues, partially
offset by increases in accounts receivable, and other current assets. The
operating cash outflows in 1997 and the nine months ended September 30, 1998
resulted from significant investments in sales, marketing and product
development, which led to operating losses. The cash outflows from operating
losses, increases in accounts receivable, prepaid expenses and other current
assets were partially offset by increases in accounts payable and accrued
liabilities and deferred revenues.
 
  Investing activities used cash of $302,000 in 1995, $2.2 million in 1996 and
$354,000 in 1997, primarily for the purchase of capital equipment and short-
term securities. Investing activities provided cash of $642,000 in the nine
months ended September 30, 1998, primarily due to proceeds from the maturity of
securities offset by cash used for the acquisition of EnCyc and the purchase of
capital equipment.
 
  Financing activities provided cash of $5,000 in 1995, $2.8 million in 1996
and $7.5 million in 1997, primarily through the issuance of preferred stock and
proceeds from the exercise of stock options, partially offset by payments on
capital equipment lease obligations. Financing activities used cash of $560,000
in the nine months ended September 30, 1998, primarily for payments on long-
term obligations.

  We currently anticipate that we will continue to experience significant
growth in our operating expenses for the foreseeable future as we enter new
markets for our products and services, increase research and development
spending, increase sales and marketing activities, develop new distribution
channels, improve our operational and financial systems and broaden our
professional service capabilities. Such operating expenses will consume a
material amount of our cash resources, including a portion of the net proceeds
of this offering. We believe that the net proceeds of this offering, together
with our existing cash and cash equivalents, tax refund and available bank
borrowings, will be sufficient to meet our anticipated cash needs for working
capital and capital expenditures for at least the next twelve months.
Thereafter, we may require additional funds to support our working capital
requirements or for other purposes and may seek to raise such additional funds
through public or private equity financing or from other sources. We may not be
able to obtain adequate or favorable financing at that time. Any financing we
do obtain may dilute your ownership interest in ONYX.
 
YEAR 2000 COMPLIANCE
 
  Many currently installed computer systems are not capable of distinguishing
21st century dates from 20th century dates. As a result, beginning on January
1, 2000, computer systems and software used by many companies and organizations
in a wide variety of industries (including technology, transportation,
utilities, finance and telecommunications) will produce erroneous results or
fail unless they have been modified or upgraded to process date information
correctly. Significant uncertainty exists in the software industry and other
industries concerning the scope and magnitude of problems associated with the
century change. We recognize the need to ensure our operations will not be
adversely affected by Year 2000 software failures. We are assessing the
potential overall impact of the impending century change on our business,
financial condition and operating results.
 
  Based on our assessment to date, we believe the current versions of our
software products are "Year 2000 compliant"--that is, they are capable of
adequately distinguishing 21st century dates from 20th century dates. However,
our products are generally integrated into enterprise systems involving
sophisticated hardware and complex software products that may not be Year 2000
compliant. We may face claims based on Year 2000 problems in other companies'
products, or issues arising from the integration of multiple products within an
overall system. Although we have not been a party to any litigation or
arbitration proceeding to date involving our products or services related to
Year 2000 compliance issues, we may in the future be required to defend our
products or services in such proceedings, or to negotiate resolutions of claims
based on Year 2000 issues. The costs of defending and resolving Year 2000-
related disputes, regardless of the merits of such disputes, and any liability
we have for Year 2000-related damages, including consequential damages, could
materially adversely affect our business, financial condition and operating
results. In addition, we believe that the purchasing patterns of customers and
potential customers may be affected by Year 2000 issues as companies expend
significant resources to correct or upgrade their current software systems for
Year 2000 compliance. These expenditures may result in reduced funds available
to purchase software products such as those we offer. To the extent Year 2000
issues cause a significant delay in, or cancellation of, decisions to purchase
our products or services, our business, financial condition and operating
results would be materially adversely affected.
 
  We are reviewing our internal management information and other systems to
identify any products, services or systems that are not Year 2000 compliant and
to take corrective action. To date, we have not encountered any material Year
2000 problems with our computer systems or any other equipment that might be
subject to such problems. We plan to verify compliance by external vendors that
supply us with software and information systems and to communicate with
significant suppliers to determine the readiness of third parties' remediation
of their own Year 2000 issues. As part of our assessment, we are evaluating the
level of validation we will require of third parties to ensure their Year 2000
readiness. If third parties cannot provide us with products, services or
systems that meet the Year 2000 requirements on a timely basis, our business,
financial condition and operating results could be materially adversely
affected. We do not expect the total cost of these Year 2000 compliance
activities to be material to our business, financial condition and operating
results. These costs and the timing with which we plan to complete our Year
2000 modifications and testing processes are based on our management's
estimates. However, we may not identify and remediate all significant Year 2000
problems on a timely basis. Remediation efforts may involve significant time
and expense and unremediated problems could materially adversely affect our
business, financial condition and operating results.

competitive and dynamic business environment.
 
INDUSTRY BACKGROUND
 
  In recent years, many enterprises have sought to use technology to improve
interactions with their customers. Many of these enterprises have implemented
customer interaction software ("CIS") systems to automate separate departments,
such as sales, marketing and customer service and support. For example, sales
force automation ("SFA") software has improved how sales departments manage
customer contacts and sales opportunities. Forrester Research estimates that
the aggregate customer applications market was $950 million in 1997 and will
grow to $3.5 billion by 2000.
 
  As the competitive and operational pressures in today's business environment
have increased, many enterprises have adopted CIS applications to help address
these challenges. Traditionally, organizations utilizing UNIX- and mainframe-
based CIS applications to manage enterprise relationships have been hindered by
long development cycles and significant costs of ownership. Recently,
improvements in the affordability and flexibility of client-server technologies
have enabled enterprises of all sizes to adopt advanced technologies that were
previously available only to large enterprises with significant IT resources.
These technology developments include
 
  .  improvements in the scalability and performance of powerful, low-cost
     "Wintel" servers and PCs, which are replacing traditional UNIX client-
     server systems;
 
  .  adoption of the Internet and corporate intranets and extranets as
     channels of internal and external corporate communication; and
 
  .  use of object-oriented programming languages, which have significantly
     improved the functionality and accessibility of enterprise software
     applications.
 
  These technology developments have also significantly contributed to the
rapid penetration of the Windows NT and Microsoft BackOffice platforms within
corporate enterprises. International Data Corporation projects that the
installed base of Windows NT-based servers will increase from 1.6 million in
1997 to 5.9 million in 2002.

         [GRAPHIC OF PROJECTED WORLDWIDE MICROSOFT NT INSTALLED BASE] 
 
  As these technology developments have made advanced software applications
more widely available, organizations have begun to adopt a new approach to
managing their enterprise relationships, called Enterprise Relationship
Management. This relationship-centric approach automates the customer lifecycle
by creating a single repository of marketing, sales and service information
that is accessible throughout the enterprise. In an attempt to provide a
comparable solution, traditional CIS application vendors have bundled
departmental applications into product suites to provide more comprehensive
relationship management capabilities. These solutions, however, remain limited
in their ability to distribute and share information. In addition, many of
these applications require significant customization and ongoing support.
 
  We believe there is a market opportunity for an ERM system that employs
recent technological developments to enable enterprises competing in today's
challenging and dynamic business environment to more effectively acquire,
manage and retain customers, partners and other relationships. This solution
would provide a high return on investment by improving the effectiveness of
sales, marketing and support activities while maintaining a low total cost of
ownership.

Offers an Integrated   The ONYX ERM solution integrates functional departments
Approach to            of an enterprise around common relationships. This
Enterprise             integrated solution provides an enterprise with a
Relationship           relationship-centric approach to automating all its
Management             business-critical relationships, instead of automating
                       individual functional departments. We use a
                       distributed, common data model which, unlike CIS, SFA
                       or other point solutions, creates a single repository
                       of marketing, service and sales information that is
                       accessible throughout the enterprise. Each employee can
                       access a unified view of an enterprise's interactions
                       with a customer, thereby improving the enterprise's
                       ability to satisfy the customer's needs.
 
Enables Rapid          We have designed the ONYX ERM solution to be rapidly
Deployment             deployable throughout the enterprise, thereby enabling
                       customers to generate a higher return on investment. On
                       average, customers have completed initial deployments
                       of ONYX applications in eight to ten weeks.

                       collaboration across the organization through a
                       consistent, easy-to-use "dashboard" interface. This
                       common interface enables access to relationship
                       information from both client-server and Web-based
                       applications.
 
Yields Lower Total     We have specifically designed our solution to be a
Cost of Ownership      flexible application that is well suited for rapidly
                       growing enterprises demanding highly functional
                       solutions without the high cost of ownership associated
                       with traditional client/server implementations. The
                       ONYX ERM solution provides out-of-the-box functionality
                       that lowers acquisition, implementation, consulting and
                       education costs, while allowing customers to tailor the
                       application to their business methodologies using
                       preconfigured templates.
 
Provides Scalability   We designed the ONYX ERM solution to support the growth
                       of our customers as they add new users and process
                       increased volume of transactions. Independent studies
                       run on our product and those of our competitors in
                       Microsoft scalability labs showed our product's ability
                       to scale to 5,000 concurrent users in a simulated
                       production environment.
 
Uses Latest            We designed our products to operate exclusively on the

                       systems for these platforms. Our solution has been
                       designed to extend all front-office information across
                       the enterprise and to the extended enterprise,
                       including customers, vendors and partners, through the
                       use of the Internet, as well as corporate intranets and
                       extranets.
 
STRATEGY
 
  Our objective is to establish a market leadership position in the ERM market.
Our strategy includes the following key elements
 
Exploit Growing        We designed the ONYX ERM solution to be quickly and
Demand for Rapidly     efficiently adopted, installed and deployed in mid- to
Deployable, Low-       large-sized enterprises, including divisions of Fortune
Cost Solutions         500 companies. The length and high cost of deployment
                       of traditional high-end customized ERM products are
                       unacceptable to growing numbers of enterprises.
                       Competitive pressures encourage enterprises of all
                       sizes to adopt

                       IT solutions that can be deployed quickly, offer
                       extensive capabilities that meet business-critical
                       needs and provide interfaces that minimize user
                       training and facilitate incremental upgrade, extension
                       and scalability paths. We plan to continue to design
                       our products to maintain low total cost of ownership.
 
Build on Market        For the foreseeable future, we plan to focus
Leadership Position    exclusively on the Windows NT platform and build on our
in Windows NT ERM      market leadership position in Windows NT-based ERM
                       solutions. The Windows NT platform is rapidly gaining
                       share in the enterprise computing market. A recent
                       International Data Corporation study stated that
                       Windows NT-based solutions are the most popular
                       corporate choice for new customer relationship
                       management solutions. We believe our products have a
                       competitive advantage in leveraging the Windows NT
                       platform because they were conceived, designed and
                       implemented to optimize Microsoft technology.
 
Expand                 We plan to expand our global operations by investing in
Internationally        our sales channels in major international markets and
                       building new localized products. Our products are
                       currently available in Spanish and German and are
                       installed and operational in 22 countries worldwide.
 
Maintain Industry-     We plan to maintain industry-leading customer
Leading Customer       satisfaction through high-quality products, superior
Satisfaction           implementation and responsive customer service and
                       support. A recent study by CustomerSat.com, sponsored
                       by us and some of our competitors, concluded that we
                       exceeded the average customer satisfaction index
                       achieved by our competition on all analyzed customer
                       satisfaction attributes. We strive to maintain this
                       position because we believe it is a critical
                       differentiator and gives us a significant competitive
                       advantage.
 
Expand Strategic       We are actively adding both channel and technology
Partnerships           partners. We believe that expanding our channel
                       partnerships will provide us with increasing access to
                       various geographic markets and potential customers. In
                       addition, we are forming strategic relationships that
                       enhance the integration with our partners' technology
                       to expand our product functionality.
 
Use Internet           We are developing new products and enhancing our
Technology             current products to provide greater Internet
                       connectivity and deploy Web-based technologies. The
                       Internet enables ERM information to be available to
                       sales and service professionals, prospects, partners
                       and customers.

 ONYX Technology
 
  ONYX's products are based on a 32-bit client/server architecture and use
industry-standard, low cost modular components. This combination of robust
technology and flexible design enables us to offer an attractive combination of
reliability, performance, scalability, integration and low total cost of
ownership. Following are the key technologies that enable ONYX to provide a
robust ERM solution:
 
  Optimized for Windows NT and SQL Server. The ONYX ERM solution is optimized
for Windows NT and SQL Server in both LAN and WAN environments in the following
ways:
 
  .uses precompiled stored procedures;
 
  .uses Microsoft vendor-specific extensions to the ANSI 92 SQL standard;
 
  .uses Microsoft vendor-specific object interface (COM); and
 
  .optimizes data model architecture for the SQL Server query engine and data
  storage engine.
 
  n-tiered Architecture. The ONYX ERM solution consists of a relationship-
centric, integrated data model surrounded by a set of configurable business
objects. This architecture utilizes multiple tiers to deliver a balance between
configurability, performance and administration. The logical tiers are: User
Services (presentation layer), Business Services (business rules) and Data
Services (data access and data store). All tiers can be customized, and
customizations can be preserved during system upgrades.
 
  Configuration. To adapt to rapidly changing business needs, the ONYX ERM
solution provides the following technologies:
 
  .  Enterprise Configurable Procedures. The ONYX architecture allows
     customization of standard business rules and procedures through
     accessible and configurable software programming code. These Enterprise
     Configurable Procedures are implemented as SQL-stored procedures and are
     written in Transact-SQL, a vendor-specific implementation of ANSI 92
     SQL. This enables more robust customization than traditional GUI-based
     configuration methods and enables these customized business rules to be
     preserved during system upgrades. Using Transact-SQL as the scripting
     language also enables the same business rules to be used online and
     offline.
 
  .  External Data Connectivity. External Data Connectivity enables
     integration with other business applications and legacy systems, as well
     as customization of the core product. Standard External Data
     Connectivity is a data-driven architecture coupled with a graphical
     administration tool that allows administrators to integrate data
     residing outside the ONYX Customer Center solution with the ONYX
     enterprise client. Standard External Data Connectivity is particularly
     focused on integration with Windows NT/Microsoft BackOffice-based
     solutions. Common Object Model ("COM") External Data Connectivity
     utilizes industry-standard COM interfaces to enable broader integration,
     specifically with any ODBC-compliant database and custom forms.
 
  .  Software Development Kits. To increase the breadth and depth of
     solutions available for the ONYX ERM solution, we have developed
     products that include integration platforms consisting of COM
     presentation objects and business objects allowing bi-directional
     integration between ONYX products and other business applications.
 
  Real-time synchronization architecture. Real-time synchronization
architecture ensures that, upon completion of synchronization between the
mobile client and enterprise database, the mobile user's data snapshot is a
replica of the enterprise database. In addition, our architecture provides
robust error detection and recovery by automatically restarting the data
synchronization process at the point of failure should a connectivity link
fail. Our synchronization system also provides robust, configurable data
conflict resolution algorithms and enables synchronization to be performed
without user intervention or attention.
 
  Integrated data model. The ONYX ERM solution includes a relationship-centric,
integrated data model--every task, form, campaign, opportunity management form,
forecasting tool and any other feature can be
 
                                       39
<PAGE>
 
interrelated at any time within the application. This fundamental part of the
architecture allows any relationship information to be shared with any other
part of the organization and ensures that every user within an organization has
access to the same data. This data model also provides flexibility to make
additions and changes to the application as the needs of the enterprise change
over time.
 
  Multiple interface support. Due to the architectural design enabling
integration in front of the business rules, the ONYX ERM platform supports
multiple interfaces, including Windows desktop applications, Web applications
and personal digital assistants.
 
  Standards-based tools and components. Our products employ an n-tiered
client/server architecture built on the Windows NT, Microsoft BackOffice,
Microsoft Office and Microsoft Windows 95 and Windows 98 operating systems.
ONYX utilizes advanced object-oriented development tools and technologies in
the development of its products, including Microsoft Visual C++, Microsoft
Visual Basic, Microsoft OLE2/COM/ActiveX, Sybase SQL Anywhere, PLATINUM ERwin
relational database modeling tool, Rational Rose object modeling tool and
Rational SQA Manager test automation tool.

 American Express   American Express Financial Advisors is one of the leading
 Financial Advisors financial services companies in the United States and has
                    approximately $188.8 billion under management. Three
                    divisions of American Express Financial Advisors use the
                    ONYX ERM solution. One division, Retirement Services, uses
                    the ONYX ERM solution in Sales, Marketing, and Client
                    Services, which has allowed them to be more customer
                    focused and has improved their ability to manage client
                    information from the initial point of contact. It also
                    allows for improved visibility into the other business

                    UK Call Centre of the Year award by UK Computing Magazine.
                    In addition to supporting large and varied call volumes,
                    ONYX Customer Center is also directly integrated with NTL
                    Internet's sales and marketing Web site, where NTL Internet
                    receives over 500 sales leads daily. NTL Internet utilizes
                    ONYX Web Wizards for Sales to automatically populate its
                    customer database with this lead information and uses ONYX
                    Web Wizards for Sales to then distribute this lead
                    information to the appropriate follow-up personnel. Using
                    the ONYX ERM solution, NTL Internet has converted a
                    significant number of these Web-based leads into sales.
 Sierra Health      Sierra Health Services, Inc. ("Sierra"), a diversified
 Services, Inc.     health care services company, selected ONYX as its ERM
                    solution provider for managing marketing, sales and service
                    activities for direct relationships with individual
                    Medicare customers, commercial accounts and brokers. In the
                    Medicare segment, Sierra utilizes the ONYX ERM solution to
                    manage its direct marketing, sales and service activities.
                    The ONYX ERM solution enables Sierra to generate lists of
                    Medicare prospects based on a variety of segmentation
                    criteria, which can then be used to automatically send
                    direct marketing materials to Medicare prospects. Telesales
                    representatives use the ONYX ERM solution to schedule
                    prospect appointments. This integrated process enables
                    Sierra to carefully track rates of conversion from
                    competitive plans and measure the effectiveness of each
                    marketing campaign. Sierra also utilizes the ONYX ERM
                    solution to manage its commercial account relationships. A
                    majority of Sierra's commercial accounts are acquired from
                    brokers who sell its plans directly to employer groups.
                    Sales opportunity tracking, forecasting and quote/contract
                    generation is managed with the ONYX ERM solution, enabling
                    Sierra to better forecast revenues and identify top
                    producing brokers with which to align itself. With the ONYX
                    ERM solution, Sierra is able to quickly provide its brokers
                    and prospective group members with updated benefit/plan
                    information, thereby allowing Sierra to improve quote
                    generation times, reduce the contracting cycle and improve
                    overall customer response and satisfaction.

SALES AND MARKETING
 
  We market and sell our software and services through a direct sales force, as
well as through distributors. We have direct sales offices in the United
States, the United Kingdom, Singapore and Australia and distributors in Latin
America, Asia and Europe. As of September 30, 1998, we employed 120 people in
sales and marketing. We support our field sales force with telemarketing
representatives and sales engineers. The direct sales effort is complemented by
indirect channel partners in many of our international markets.
 
  Our marketing programs are focused on creating awareness, preference and lead
generation for the ONYX ERM solution. These programs are targeted at key
executives such as Chief Executive Officers and Chief Information Officers, as
well as Vice Presidents of Sales, Service and Marketing.
 
  To support our worldwide direct and indirect sales channels, we have
sponsored a series of joint seminars with key customers and partners, such as
Microsoft. Our marketing personnel engage in a variety of marketing activities,
including managing and maintaining the ONYX Web site, making direct mailings,
placing advertisements, conducting public relations programs and establishing
and maintaining relationships with recognized industry analysts.
 
  We also have initiated a branding and marketing communications strategy to
solidify our position as a leading provider of ERM software. This effort
includes new messaging, target positioning, a new "look and feel" and an
increased effort to broaden market awareness of ONYX. We have also initiated
marketing strategies targeted at industry-specific vertical markets, including
high technology, financial services, health care, telecommunications and
manufacturing.
 
  Our sales process consists of several phases: lead generation, initial
contact, lead qualification, needs assessment, enterprise overview, product
demonstration, proposal generation and contract negotiation. In a number of
instances, we believe that our relationships with strategic partners, including
systems integrators, has substantially shortened our sales cycle. Partners have
generated and qualified sales leads, made initial customer contacts and
assessed needs prior to our introduction. Additionally, systems integration
partners have assisted us in the creation of customized presentations and
demonstrations, which we believe enhance our competitive position. While the
sales cycle varies substantially from customer to customer, the initial sales
cycle typically ranges from two to six months (although in the past certain
sales cycles have lasted substantially longer).
 
  We have distribution partners located in Europe, Asia, Latin America and the
South Pacific who market, promote and sell our software products. Our
distributors also typically provide both the implementation and customer
support services to our end-users, drawing on our expertise as necessary to
assist them in these efforts. We collaborate with our distributors in a variety
of areas, including seminars, trade shows and conferences. Our distributors
also create market- and language-specific collateral and product demonstrations
and assist in the localization of our products and related documentation.
 
RESEARCH AND DEVELOPMENT
 
  As of September 30, 1998, we employed 65 people in our research and
development organization. This team is responsible for the design, development
and release of ONYX products. The group is organized into four disciplines:
development, quality assurance, documentation and program management. Members
from each of these disciplines, along with a product manager from our marketing
department, form separate product teams that work closely with sales,
marketing, professional services, customers and prospects to better understand
market needs and requirements. When required, we also utilize third-party
development firms to expand the capacity and technical expertise of our
internal research and development team. Additionally, we sometimes license
third-party technology that is incorporated into our products. We believe this
approach significantly shortens our time to market without compromising our
competitive position or product quality. Therefore, we expect to continue to
draw on third-party resources in the foreseeable future.
 
 
                                       42
<PAGE>
 
  We have a well-defined software development methodology that we believe
allows us to deliver products that satisfy real business needs for the global
market and meet commercial quality expectations. This methodology is based on
the following key components:
 
  .  specification and review of business requirements, functional
     requirements, prototypes, technical designs, test plans and
     documentation plans;
 
  .  iterative, scheduled quality assurance of code and documentation;
 
  .  frequent stabilization of product;
 
  .  test automation definition, instrumentation and execution;
 
  .  test functions, components, systems, integration, performance, stress
     and international and year 2000 compliance;
 
  .  full product regression testing before beta or general availability
     releases;
 
  .  trial deployments in an internal production environment prior to
     release;
 
  .  external beta releases; and
 
  .  general availability release.
 
  We emphasize quality assurance throughout the software development life
cycle. We believe that strong emphasis placed on analysis and design early in
the project life cycle reduces the number and costs of defects that may be
found in later stages. Our development methodology focuses on delivery of
product to a global market, enabling localization into multiple languages from
a single code base.
 
INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS
 
  Our success depends in part on our ability to protect our proprietary rights.
To protect our proprietary rights, we rely primarily on a combination of
copyright, trade secret and trademark laws, confidentiality agreements with
employees and third parties, and protective contractual provisions such as
those contained in license agreements with consultants, vendors and customers,
although we have not signed such agreements in every case. Despite our efforts
to protect our proprietary rights, unauthorized parties may copy aspects of our
products, and obtain and use information that we regard as proprietary. Other
parties may breach confidentiality agreements and other protective contracts we
have entered into, and we may not become aware of, or have adequate remedies in
the event of, such breach.
 
  We pursue the registration of certain of our trademarks and service marks in
the United States and in certain other countries, but we have not secured
registration of all our marks. In addition, the laws of some foreign countries
do not protect our proprietary rights to the same extent as do the laws of the
United States, and effective copyright, trademark and trade secret protection
may not be available in other jurisdictions. A significant portion of our marks
include the word "Onyx." Other companies use "Onyx" in their marks alone or in
combination with other words, and we cannot prevent all third-party uses of the
word "Onyx." We license certain proprietary rights to third parties. Such
licensees may not abide by compliance and quality control guidelines with
respect to such proprietary rights and may take actions that would materially
adversely affect our business, financial condition and operating results.
 
  We have been subject to claims and expect to be subject to legal proceedings
and claims from time to time in the ordinary course of our business, including
claims of alleged infringement of trademarks and other intellectual property
rights of third parties. See "--Legal Proceedings." OCI has filed a lawsuit
against us alleging trademark infringement of the mark ONYX in Canada. This
claim, even if not meritorious, could require the expenditure of significant
financial and managerial resources. A negative outcome could materially
adversely affect our business, financial condition and operating results.
 
  Other than the trademark infringement matter described above, as of the date
of this prospectus, we are not a party to any litigation that, if adversely
determined, would have a material adverse effect on our business, financial
condition and operating results.
 
                                       43
<PAGE>
 
  In the computer software market there is frequent and substantial
intellectual property litigation, which is often complex and expensive, and
involves a significant diversion of resources and uncertainty of outcome. We
may need to litigate to enforce and protect our intellectual property or to
defend against a claim of infringement or invalidity. Although we attempt to
avoid infringing known proprietary rights of third parties in our product
development efforts, we have been and expect to continue to be subject to legal
proceedings and claims from time to time in the ordinary course of our
business, including claims of alleged infringement of third-party proprietary
rights by us and our licensees. In addition, we expect that software developers
will be increasingly subject to infringement claims as the number of products
and competitors in our industry grows and the functionality of products in
different industry segments overlaps. Furthermore, former employers of our
present and future employees may assert claims that our employees have
improperly disclosed confidential or proprietary information to us. If we
discover that any elements of the ONYX Customer Center product family violate
third-party proprietary rights, we may be unable to obtain licenses on
commercially reasonable terms, if at all, and to avoid or settle litigation
without substantial expense and damage awards. Any claims relating to the
infringement of third-party proprietary rights, even if not meritorious, could
result in costly litigation, divert management's attention and resources, cause
product shipment delays or require us to pay damages or enter into royalty or
license agreements on terms that are not advantageous to us. Any of these
results could materially adversely affect our business, financial condition and
operating results.
 
  We rely on certain technology that we license from third parties, including
software that is integrated with internally developed software and used in our
products, to perform key functions. Although we are generally indemnified
against claims that such third-party technology infringes the proprietary
rights of others, such indemnification is not always available for all types of
intellectual property rights, and in some cases the scope of such
indemnification is limited. Even if we receive broad indemnification, third-
party indemnitors are not always well capitalized and may not be able to
indemnify us in the event of infringement, resulting in substantial exposure to
us. Infringement or invalidity claims arising from the incorporation of third-
party technology, and claims for indemnification from our customers resulting
from such claims, may be asserted or prosecuted against us. 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, and could materially adversely affect our business, financial
condition and operating results. See "Risk Factors--We may be unable to
adequately protect our proprietary rights."
 
COMPETITION
 
  The market for ERM software is intensely competitive, fragmented and rapidly
changing. We believe that we compete effectively as a result of our integrated,
relationship-centric, rapidly deployable, Internet-enabled solution that is
optimized for the Windows NT platform, coupled with our commitment to providing
high-quality solutions that yield a rapid return on investment and a low total
cost of ownership.
 
  We face competition in the ERM software market primarily from (1) front-
office software applications vendors, such as Clarify, Inc., Pivotal Corp.,
SalesLogix Corporation, Siebel Systems, Inc., and The Vantive Corporation, (2)
large enterprise software vendors, particularly ERP system vendors, such as
Baan Company N.V., J. D. Edwards & Co., Oracle Corporation, PeopleSoft
Corporation and SAP AG, and (3) our potential customers' IT departments, which
may seek to develop proprietary ERM systems. In addition, as we develop new
products, particularly applications focused on particular 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 that enable them to rapidly increase their
market share.
 
  Many of our competitors have already established supplier relationships with
divisions of our current or potential customers. These competitors may be able
to leverage their existing relationships to discourage these customers from
purchasing additional ONYX products or persuade them to replace our products
with their products. Many of our competitors have longer operating histories,
significantly greater resources and name recognition and a larger installed
base of customers than we have. As a result, these competitors may have greater
credibility with our existing and potential customers. They also may be able to
devote greater resources
 
                                       44
<PAGE>
 
to the development, promotion and sale of their products than we can to ours,
which would allow them to respond more quickly than we can to new or emerging
technologies and changes in customer requirements.
 
  We expect that competition will increase as other established and emerging
companies enter the ERM market, as new products and technologies are introduced
and as new competitors enter the market. Increased competition may result in
price reductions, lower gross margins and loss of our market share, any of
which could materially adversely affect our business, financial condition and
operating results. See "Risk Factors--Our market is highly competitive."
 
EMPLOYEES
 
  As of September 30, 1998, we had a total of 281 employees, excluding
independent contractors and other temporary employees, including 65 people in
research and development, 120 people in sales and marketing, 64 people in
consulting, customer support and training and 32 people in general and
administrative services. Our future performance depends in significant part on
the continued service of our key technical, sales and senior management
personnel. The loss of the services of one or more of our key employees could
have a material adverse effect on our business, financial condition and
operating results. Our future success also depends on our continuing ability to
attract, train and retain highly qualified technical, sales and managerial
personnel. Competition for such personnel is intense. We cannot provide any
assurance that we can retain our key technical, sales and managerial personnel
in the future. None of our employees is represented by a labor union, and we
consider our employee relations to be good. See "Risk Factors--We may
experience difficulties managing our growth, and we depend on certain key
employees."
 
FACILITIES
 
  Our principal administrative, sales, marketing, support and research and
development facilities are located in approximately 38,500 square feet of space
in Bellevue, Washington. Our principal lease, covering 33,000 square feet of
this office space, expires on June 30, 1999. The remaining leases expire
between June 1999 and January 2002. In July 1999, we plan to relocate our
principal administrative, sales, marketing, support and research and
development facilities to a new location in Bellevue, Washington with
approximately 90,000 square feet, pursuant to a lease that expires in 2006. We
currently lease other domestic sales and support offices in California,
Colorado, Georgia, Illinois, Maryland, Massachusetts, Minnesota, New Jersey,
Oregon and Texas. We maintain international offices in Australia, Singapore and
the United Kingdom.
 
LEGAL PROCEEDINGS
 
  We have been subject to claims and expect to be subject to legal proceedings
and claims from time to time in the ordinary course of our business, including
claims of alleged infringement of trademarks and other intellectual property
rights of third parties. See "Risk Factors--We may be unable to adequately
protect our proprietary rights." OCI has filed a lawsuit against us alleging
trademark infringement of the mark ONYX in Canada. This claim, even if not
meritorious, could require the expenditure of significant financial and
managerial resources. A negative outcome could materially adversely affect our
business, financial condition and operating results.
 
  Other than the trademark infringement matter described above, as of the date
of this prospectus, we are not a party to any litigation that, if adversely
determined, would have a material adverse effect on our business, financial
condition and operating results.

involving intentional misconduct or knowing violations of law, (2) unlawful
distributions, or (3) transactions from which the director personally receives
a benefit in money, property or services to which the director is not legally
entitled. The Restated Articles also provide that we shall indemnify any
individual made a party to a proceeding because that individual is or was a
director of ONYX and shall advance or reimburse reasonable expenses incurred by
such individual in advance of the final disposition of the proceeding to the
full extent permitted by applicable law. Any repeal of or modification to the
Restated Articles may not adversely affect any right of a director of ONYX who
is or was a director at the time of such repeal or modification. To the extent
the provisions of the Restated Articles provide for indemnification of
directors for liabilities arising under the Securities Act of 1933, as amended
(the "Securities Act"), those provisions are, in the opinion of the Commission,
against public policy as expressed in the Securities Act and they are therefore
unenforceable.
 
  The Restated Bylaws provide that we shall indemnify our directors and
officers and may indemnify our employees and agents to the full extent
permitted by law. In addition, we intend to enter into separate indemnification
agreements with our directors and executive officers that could require us,
among other things, to indemnify them against certain 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 intend to purchase and 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 directors and officers of ONYX.
 
                                       48

  We believe that the limitation of liability provision in the Restated
Articles, the indemnification provisions in the Restated Bylaws, the
indemnification agreements and the liability insurance policy will facilitate
our ability to continue to attract and retain qualified individuals to serve as
directors and officers of ONYX.

EMPLOYEE BENEFIT PLANS
 
 1998 Stock Incentive Compensation Plan
 
  The Board of Directors and shareholders have adopted the 1998 Plan. The
purpose of the 1998 Plan is to enhance long-term shareholder value by offering
opportunities to employees, directors, officers, consultants, agents, advisors
and independent contractors of ONYX and its subsidiaries to participate in
ONYX's growth and success, and to encourage them to remain in the service of
ONYX and its subsidiaries and to own ONYX stock. The 1998 Plan provides for
awards of stock options and restricted stock. The Board has reserved a total of
(1) 1,500,000 shares of common stock (plus 18,872 shares that have been
reserved but unissued under the 1994 Plan), (2) any shares returned to the 1994
Plan upon termination of options or repurchase of shares by ONYX and (3) an
automatic annual increase, to be added on the first day of our fiscal year
beginning in 2000, equal to the lesser of 1,675,763 shares or 5% of the average
common shares outstanding as used to calculate fully diluted earnings per share
as reported in ONYX's Annual Report for the preceding year. As of November 30,
1998, options to purchase 16,200 shares of common stock were outstanding under
the 1998 Plan with exercise prices of $9.00 per share, options to purchase
1,502,672 shares were available for grant and no options had been exercised.
 
  Stock Option Grants. The Compensation Committee will serve as the Plan
Administrator of the 1998 Plan. The Plan Administrator will have the authority
to select individuals to receive options under the 1998 Plan and to specify the
terms and conditions of each option granted (incentive or nonqualified), the
exercise price (which, for incentive stock options, must be at least equal to
the fair market value of the common stock on the date of grant), the vesting
provisions and the option term. For purposes of the 1998 Plan, fair market
value means the average of the high and low per share sales price as reported
on the Nasdaq National Market on the date of grant. Unless otherwise provided
by the Plan Administrator, and to the extent required for incentive stock
options by the Code, an option granted under the 1998 Plan will expire ten
years from the date
 
                                       49
<PAGE>
 
of grant or, if earlier, three months after the optionee's termination of
service (other than termination for cause) or one year after the optionee's
death or disability.
 
  Stock Awards. The Plan Administrator is authorized under the 1998 Plan to
issue shares of common stock to eligible participants with terms, conditions
and restrictions established by the Plan Administrator in its sole discretion.
Restrictions may be based on continuous service with ONYX or its subsidiaries
or the achievement of performance goals. Holders of restricted stock are
shareholders of ONYX and have, subject to certain restrictions, all the rights
of shareholders with respect to such shares.
 
  Adjustments. The Plan Administrator will make proportional adjustments to the
aggregate number of shares issuable under the 1998 Plan and to outstanding
awards in the event of stock splits or other capital adjustments.
 
  Corporate Transactions. In the event of certain corporate transactions, such
as a merger or sale of ONYX, each outstanding option and restricted stock award
will automatically accelerate and become 100% vested immediately before the
corporate transaction, unless the option or restricted stock award is, in
connection with the corporate transaction, assumed by ONYX's successor
corporation or parent thereof. Any option or restricted stock award granted to
an "executive officer" (as defined for purposes of Section 16 of the Securities
Exchange Act of 1934, as amended (the "Exchange Act")) that is assumed or
replaced in the corporate transaction will automatically accelerate in the
event the executive officer terminates his or her employment for certain
specified good reasons, or the successor corporation terminates the executive
officer's employment or services without cause within two years following the
corporate transaction.
 
 1998 Employee Stock Purchase Plan
 
  The Board of Directors adopted the ESPP in December 1998, subject to
shareholder approval. If the ESPP is approved by our shareholders, we will
implement it upon the effectiveness of this offering. We intend for the ESPP to
qualify under Section 423 of the Code. The ESPP permits eligible employees of
ONYX and its subsidiaries to purchase common stock through payroll deductions
of up to 10% of their compensation. Under the ESPP, no employee may purchase
common stock worth more than $25,000 in any calendar year, valued as of the
first day of each offering period. In addition, owners of 5% or more of ONYX's
or a subsidiary's common stock may not participate in the ESPP. We authorized
the issuance under the ESPP of a total of 500,000 shares of common stock, plus
an automatic annual increase, to be added on the first day of our fiscal year
beginning in 2000, equal to the lesser of (a) 200,000 shares and (b) 1.2% of
the average common shares outstanding as used to calculate fully diluted
earnings per share as reported in ONYX's Annual Report for the preceding year,
or a lesser amount determined by the Board of Directors. Any shares from
increases in previous years that are not actually issued shall be added to the
aggregate number of shares available for issuance under the ESPP.
 
  We will implement the ESPP with six-month offering periods. The first
offering period will commence on the effectiveness of this offering. Subsequent
offering periods will begin on each January 1 and July 1. The price of the
common stock purchased under the ESPP will be the lesser of 85% of the fair
market value on the first day of an offering period and 85% of the fair market
value on the last day of an offering period, except that the purchase price for
the first offering period will be equal to the lesser of 100% of the initial
public offering price of the common stock and 85% of the fair market value on
June 30, 1999. The ESPP terminates ten years after the date of adoption by the
Board of Directors, but the Board of Directors may terminate it at any earlier
time. We have not yet issued any shares of common stock under the ESPP.
 
  In the event of a merger, consolidation or acquisition by another corporation
of all or substantially all of our assets, each outstanding option to purchase
shares under the ESPP shall be assumed or an equivalent option substituted by
the successor corporation. If the successor corporation refuses to assume or
substitute for the option, 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 a proposed liquidation or dissolution of
ONYX,
 
                                       50
<PAGE>
 
the offering period during which a participant may purchase stock will be
shortened to a specified date before the date of the proposed liquidation or
dissolution.
 
 1994 Combined Incentive and Nonqualified Stock Option Plan
 
  The Board of Directors and shareholders have adopted the 1994 Plan and
reserved an aggregate of 5,000,000 shares of common stock for grants of stock
options under the 1994 Plan. The 1994 Plan provides for the grant of options
for common stock to employees, directors, consultants or independent
contractors of ONYX or its subsidiaries. As of November 30, 1998, options to
purchase 3,388,252 shares of common stock were outstanding under the 1994 Plan
with exercise prices ranging from $0.10 to $9.00 per share and options for
1,592,876 shares had been exercised. The Board of Directors of ONYX has
suspended the 1994 Plan and determined that no further grants shall be made
pursuant to the 1994 Plan.
 
  The 1994 Plan is administered by the Board of Directors. The Board of
Directors has the authority to select individuals who are to receive options
under the 1994 Plan and to specify the terms and conditions of each option so
granted (incentive or nonqualified), the vesting provisions, the option term
and the exercise price. Options granted under the 1994 Plan must be exercised
within three months of the optionee's termination of service (as defined in the
1994 Plan) to or employment by ONYX, or within one year after the optionee's
termination by death or disability, but in no event later than the expiration
of the option term. Options granted under the 1994 Plan are not transferable by
the optionee, except by will or the laws of descent and distribution, and
generally are exercisable during the optionee's lifetime only by the optionee.
 
  In the event of a merger, consolidation, acquisition of property or stock,
separation, reorganization or liquidation of ONYX, as a result of which the
shareholders receive cash, stock or other property in exchange for their shares
of common stock, the Board of Directors will determine whether provision will
be made in connection with any such transaction for assumption of the options
under the 1994 Plan or substitution of appropriate new options covering the
stock of the successor corporation or an affiliate of the successor
corporation. If the Board of Directors determines that no such assumption or
substitution will be made, each outstanding option under the 1994 Plan will
automatically accelerate and become 100% vested and exercisable immediately
before the transaction. Acceleration will not occur, however, if, in the
opinion of our accountants, it would render unavailable "pooling of interest"
accounting for the transaction.
 
 401(k) Plan
 
  We maintain a 401(k) Plan that covers all our employees who satisfy certain
eligibility requirements relating to minimum age, length of service and hours
worked. We may make an annual contribution for the benefit of eligible
employees in an amount determined by the Board of Directors. We have not made
any such contribution to date and have no current plans to do so. Eligible
employees may make pretax elective contributions of up to 15% of their
compensation, subject to maximum limits on contributions prescribed by law.

  William B. Elmore and Paul G. Koontz, directors of ONYX, are Members of
Foundation Capital Management, L.L.C., which is the General Partner of
Foundation Capital, L.P. and a Member of Foundation Capital Entrepreneurs Fund,
L.L.C (collectively, the "Foundation Entities"). Jay C. Hoag, a director of

Strategic Partners, L.P. All outstanding shares of preferred stock will convert
into an aggregate of 3,533,925 shares of common stock upon the closing of this
offering.
 
  In connection with the issuances of preferred stock described above, we
entered into an Amended and Restated Investors' Rights Agreement dated as of
March 31, 1997 (the "Investors' Rights Agreement") with the holders of the
preferred stock (the "Preferred Shareholders") and certain principal
shareholders of ONYX (the "Principal Common Shareholders"), including:
 
  .  Brent R. Frei, President, Chief Executive Officer and Chairman of the
     Board of ONYX, his parents, Ronald and Glenda Frei, his sister, Colleen
     Chmelik, and his brother-in-law, James Chmelik;
 
  .  Brian M. Janssen, a former director and a principal shareholder of ONYX;
 
  .  Todd A. Stevenson, a director of ONYX, and his parents, Leon and Barbara
     Stevenson; and
 
  .  Michael and Mary Racine, principal shareholders of ONYX.
 
Pursuant to the terms of the Investors' Rights Agreement, the holders of the
Series B Preferred Stock are entitled to purchase in the initial public
offering their pro rata share of an aggregate number of shares equal to the
greater of (a) the number of shares having an aggregate offering price of
$3,000,000 and (b) 10% of the shares offered in the initial public offering;
provided, however, that the purchase amount shall not exceed the number of
shares having an aggregate offering price of $4,000,000. See "Underwriting."
Each holder of Series B Preferred Stock is also entitled to purchase its pro
rata share of any shares not purchased by the other holders of Series B
Preferred Stock. The Investors' Rights Agreement also grants to the Preferred
Shareholders and the Principal Common Shareholders certain registration rights
that obligate ONYX, under certain circumstances, to effect a registration under
the Securities Act of shares of common stock. See "Description of Capital
Stock--Registration Rights."

  In May 1998, the Technology Crossover Entities entered into a transaction
with Ronald and Glenda Frei, pursuant to which Mr. and Mrs. Frei (1) borrowed
$85,000 from the Technology Crossover Entities; (2) pledged 56,666 shares of
common stock of ONYX to secure such indebtedness (the "Frei Pledge"); and (3)
granted to the Technology Crossover Entities the right to purchase 20,000
shares of common stock at a per share price of $4.25 (the "Frei Call Option").
In connection with this transaction, we entered into a Call Option Agreement
and a Stock Pledge Agreement, pursuant to which we agreed to hold in escrow the
shares of ONYX common stock subject to the Frei Call Option and the Frei
Pledge.
 
  Also in April 1998, the Foundation Entities entered into a transaction with
Leon and Barbara Stevenson, pursuant to which Mr. and Mrs. Stevenson (1)
borrowed $425,000 from the Foundation Entities and an affiliated entity; (2)
pledged 283,331 shares of common stock to secure such indebtedness (the
"Stevenson Pledge"); and (3) granted to the Foundation Entities and an
affiliated entity the right to purchase 100,000 shares of common stock of ONYX
at a per share purchase price of $4.25 (the "Stevenson Call Option"). In
connection with this transaction, we entered into a Call Option Agreement and a
Stock Pledge Agreement, pursuant to which we agreed to hold in escrow the
shares of ONYX common stock subject to the Stevenson Call Option and the
Stevenson Pledge.
 
  The Frei Call Option and the Stevenson Call Option will terminate if not
exercised prior to the closing of this offering.
 
  In July 1998, Eben W. Frankenberg, an ONYX officer, exercised an option to
purchase 800,000 shares of common stock and paid the exercise price by issuing
a full recourse promissory note to us in the amount of $160,000. The note is
secured by 750,000 shares of the common stock issued upon exercise. The note
accrues interest at the rate of 5.39% per annum and is due in July 2001.
 
  In connection with this offering, our Board of Directors approved, and
recommended to our shareholders for approval prior to this offering, amendments
to our Articles of Incorporation that, among other things, increase by an
aggregate of 100,000 the number of shares of common stock issuable on
conversion of our Series B Preferred Stock and eliminate the minimum per share
price threshold for automatic conversion of our preferred stock upon completion
of this offering.
 
  We intend to enter into separate indemnification agreements with each of our
directors and executive officers prior to the closing of this offering. See
"Management--Director and Officer Indemnification and Liability."

 (1)  Beneficial ownership is determined in accordance with rules of the
      Commission and includes shares over which the indicated beneficial owner
      exercises voting and/or investment power. Shares of common stock subject
      to options currently exercisable or exercisable within 60 days are deemed
      outstanding for computing the percentage ownership of the person holding
      the options but are not deemed outstanding for computing the percentage
      ownership of any other person.

                          DESCRIPTION OF CAPITAL STOCK
 
  We are authorized to issue up to 40,000,000 shares of common stock, $0.01 par
value per share, and 10,000,000 shares of preferred stock, $0.01 par value per
share. The following summary of certain provisions of the common stock and
preferred stock is not complete and may not contain all the information you
should consider before investing in the common stock. You should read carefully
our Restated Articles, which are included as an exhibit to the Registration
Statement, of which this prospectus is a part.
 
COMMON STOCK
 
  As of November 30, 1998, there were 13,360,134 shares of common stock
outstanding held of record by 68 shareholders. Following this offering, there
will be    shares of common stock outstanding (assuming no exercise of the
Underwriters' over-allotment option and no exercise of outstanding options).
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 of any outstanding
shares of preferred stock, the holders of common stock are entitled to receive
ratably any dividends the Board of Directors declares out of funds legally
available for the payment of dividends. See "Dividend Policy." If ONYX is
liquidated, dissolved or wound up, the holders of common stock are entitled to
share pro rata all assets remaining after payment of liabilities and
liquidation preferences of any 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 nonassessable, and the shares of common stock to be
issued following this offering will be fully paid and nonassessable.
 
PREFERRED STOCK
 
  Upon the closing of this offering, all outstanding shares of preferred stock
will be converted into 3,533,925 shares of common stock. Thereafter, pursuant
to our Restated Articles, the Board of Directors will have the authority,
without further action by the shareholders, to issue up to 10,000,000 shares of
preferred stock in one or more series and to fix the designations, powers,
preferences, privileges and relative, participating, optional or special rights
and the qualifications, limitations or restrictions thereof, including dividend
rights, conversion rights, voting rights, terms of redemption and liquidation
preferences, any or all of which may be greater than the rights of the common
stock. The Board of Directors, without shareholder approval, can issue
preferred stock with voting, conversion or other rights that could adversely
affect the voting power and other rights of the holders of common stock.
Preferred stock could thus be issued quickly with terms that could delay or
prevent a change in control of ONYX or make removal of management more
difficult. Additionally, the issuance of preferred stock may decrease the
market price of the common stock and may adversely affect the voting and other
rights of the holders of common stock. We have no plans to issue any preferred
stock.
 
REGISTRATION RIGHTS
 
  After this offering, the holders of 11,462,158 shares of common stock will be
entitled to certain rights with respect to the registration of such shares
under the Securities Act, pursuant to the Amended and Restated Investors'
Rights Agreement among such holders and ONYX, dated March 31, 1997 (the
"Investor Rights Agreement"). Under the terms of the Investor Rights Agreement,
if we propose to register any of our securities under the Securities Act,
either for our own account or for the account of other security holders
exercising registration rights, such holders are entitled to notice of the
registration and to include shares of common stock in the registration at our
expense. Additionally, such holders are entitled to certain demand registration
rights pursuant to which they may require us to file a registration statement
under the Securities Act at our expense with respect to their shares of common
stock. Further, such holders may require us to file additional registration
statements on Form S-3 at our expense. All of these registration rights are
subject to certain conditions and
 
                                       56
<PAGE>
 
limitations, among them the right of the underwriters of an offering to limit
the number of shares included in such registration and our right to decline to
effect such a registration before the earlier of March 31, 2000 and six months
after the closing of the initial public offering.
 
ANTITAKEOVER EFFECTS OF CERTAIN PROVISIONS OF RESTATED ARTICLES, RESTATED
BYLAWS AND WASHINGTON LAW
 
  As noted above, our Board of Directors, without shareholder approval, has the
authority under our Restated Articles 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 ONYX or make removal of management more
difficult.
 
  Election and Removal of Directors. Effective with the first annual meeting of
shareholders following this offering, the Company's Restated Articles provide
for the division of our Board of Directors into three classes, as nearly as
equal in number as possible, with the directors in each class serving for a
three-year term, and one class being elected each year by our shareholders.
Directors may be removed only for cause. Because this system of electing and
removing directors generally makes it more difficult for shareholders to
replace a majority of the Board of Directors, it may tend to discourage a third
party from making a tender offer or otherwise attempting to gain control of
ONYX and may maintain the incumbency of the Board of Directors.
 
  Approval for Certain Business Combinations. Our Restated Articles require
that certain business combinations (including a merger, share exchange and the
sale, lease, exchange, mortgage, pledge, transfer or other disposition or
encumbrance of a substantial part of our assets other than in the usual and
regular course of business) be approved by the holders of not less than two-
thirds of the outstanding shares, unless such business combination has been
approved by a majority of the Board of Directors, in which case the affirmative
vote required shall be a majority of the outstanding shares.
 
  Shareholder Meetings. Under our Restated Articles and Restated Bylaws, our
shareholders may call a special meeting only upon the request of holders of at
least 25% of the outstanding shares. Additionally, the Board of Directors, the
Chairman of the Board and the President may call special meetings of
shareholders.
 
  Requirements for Advance Notification of Shareholder Nominations and
Proposals. Our Restated Bylaws establish advance notice procedures with respect
to shareholder proposals and the nomination of candidates for election as
directors, other than nominations made by or at the direction of the Board of
Directors or a committee thereof.
 
  Washington law imposes restrictions on certain transactions between a
corporation and certain significant shareholders. Chapter 23B.19 of the WBCA
prohibits a "target corporation," with certain exceptions, from engaging in
certain significant business transactions with a person or group of persons
that beneficially owns 10% or more of the voting securities of the target
corporation (an "Acquiring Person") for a period of five years after such
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. Such prohibited 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 benefit 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 ONYX.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has been no public market for the common stock.
We cannot provide any assurances that a significant public market for the
common stock will develop or be sustained after this offering. Future sales of
substantial amounts of common stock in the public market, or the possibility of
such sales occurring, could adversely affect prevailing market prices for the
common stock or our future ability to raise capital through an offering of
equity securities.
 
  After this offering, we will have outstanding    shares of common stock. Of
these shares, the    shares that we expect to sell in this offering (   shares
if the Underwriters' over-allotment option is exercised in full) will be freely
tradable in the public market without restriction under the Securities Act,
unless such shares are held by "Affiliates" of ONYX, as that term is defined in
Rule 144 under the Securities Act.
 
  The remaining 13,360,134 shares of common stock that will be outstanding
after this offering will be Restricted Shares. We issued and sold the
Restricted Shares in private transactions in reliance on exemptions from
registration under the Securities Act. Restricted Shares may be sold in the
public market only if they are registered or if they qualify for an exemption
from registration under Rule 144 or Rule 701 under the Securities Act, as
summarized below.
 
  Pursuant to certain "lock-up" agreements, all the executive officers,
directors and certain shareholders of ONYX, who collectively hold an aggregate
of 13,277,825 Restricted Shares, have agreed not to offer, sell, contract to
sell, grant any option to purchase or otherwise dispose of any such shares for
a period of 180 days from the date of this prospectus. We also have entered
into an agreement with the Underwriters that we will not offer, sell or
otherwise dispose of common stock for a period of 180 days from the date of
this prospectus.
 
  Ninety days after the date of this prospectus, 82,309 shares that are not
subject to lock-up agreements will be eligible for sale in the public market in
accordance with Rules 144 and 701. On the date of the expiration of the lock-up
agreements, an additional 13,035,597 Restricted Shares will be eligible for
immediate sale (of which 8,418,470 shares will be subject to certain volume,
manner of sale and other limitations under Rule 144). The remaining 242,228
Restricted Shares will be eligible for sale pursuant to Rule 144 on the
expiration of various one-year holding periods over the six months following
the expiration of the lock-up period.
 
  Following the expiration of such lock-up periods, certain shares issued upon
exercise of options we granted prior to the date of this prospectus will also
be available for sale in the public market pursuant to Rule 701 under the
Securities Act. Rule 701 permits resales of such shares in reliance upon Rule
144 under the Securities Act but without compliance with certain restrictions,
including the holding-period requirement, imposed under Rule 144. In general,
under Rule 144 as in effect at the closing of this offering, beginning 90 days
after the date of this prospectus, a person (or persons whose shares of ONYX
are aggregated) who has beneficially owned Restricted Shares for at least one
year (including the holding period of any prior owner who is not an Affiliate
of ONYX) would be entitled to sell, within any three-month period, a number of
shares that does not exceed the greater of (1) 1% of the then-outstanding
shares of common stock (approximately    shares immediately after this
offering) and (2) the average weekly trading volume of the common stock during
the four calendar weeks preceding the filing of a Form 144 with respect to such
sale. Sales under Rule 144 are also subject to certain manner of sale and
notice requirements and to the availability of current public information about
ONYX. Under Rule 144(k), a person who is not deemed to have been an Affiliate
of ONYX at any time during the 90 days preceding a sale and who has
beneficially owned the shares proposed to be sold for at least two years
(including the holding period of any prior owner who is not an Affiliate of
ONYX) is entitled to sell such shares without complying with the manner of
sale, public information, volume limitation or notice provisions of Rule 144.
 
                                       59

  We intend to file, after the effective date of this offering, a Registration
Statement on Form S-8 to register approximately 9,158,650 shares of common
stock reserved for issuance under the 1994 Plan, the 1998 Plan and the ESPP.
The Registration Statement will become effective automatically upon filing.
Shares issued under the foregoing Plans, after the filing of a Registration
Statement on Form S-8, may be sold in the open market, subject, in the case of
certain holders, to the Rule 144 limitations applicable to Affiliates, the
above-referenced lock-up agreements and vesting restrictions imposed by us.
 
  In addition, following this offering, the holders of 11,462,158 shares of
outstanding common stock will, under certain circumstances, have rights to
require us to register their shares for future sale. See "Description of
Capital Stock--Registration Rights."

  Under the terms and subject to the conditions contained in an Underwriting
Agreement dated      , 1999 (the "Underwriting Agreement"), the underwriters
named below (the "Underwriters"), for whom Credit Suisse First Boston
Corporation, SG Cowen Securities Corporation and Piper Jaffray Inc. are acting
as representatives (the "Representatives"), have severally but not jointly
agreed to purchase from ONYX the following respective numbers of shares of
common stock:

</TABLE>
 
  The Underwriting Agreement provides that the obligations of the Underwriters
are subject to certain conditions precedent and that the Underwriters will be
obligated to purchase all the shares of common stock offered hereby (other than
those shares covered by the over-allotment option described below) if any are
purchased. The Underwriting Agreement provides that, in the event of a default
by an Underwriter, in certain circumstances the purchase commitments of
nondefaulting Underwriters may be increased or the Underwriting Agreement may
be terminated.
 
  ONYX has granted to the Underwriters an option, expiring at the close of
business on the 30th day after the date of this prospectus to purchase up to
     additional shares at the initial public offering price less the
underwriting discounts and commissions, all as set forth on the cover page of
this prospectus. Such option may be exercised only to cover over-allotments in
the sale of shares of common stock. To the extent such option is exercised,
each Underwriter will become obligated, subject to certain conditions, to
purchase approximately the same percentage of such additional shares of common
stock as it was obligated to purchase pursuant to the Underwriting Agreement.
 
  ONYX has been advised by the Representatives that the Underwriters propose to
offer the shares to the public initially at the public offering price set forth
on the cover page of this prospectus and, through the Representatives, to
certain dealers at such price less a concession of $  per share, and the
Underwriters and such dealers may allow a discount of $  per share on sales to
certain other dealers. After the initial public offering, the public offering
price and concession and discount to dealers may be changed by the
Representatives.
 
  The following table summarizes the compensation to be paid to the
Underwriters by ONYX, and the expenses payable by ONYX.

  The Representatives have informed ONYX that they do not expect discretionary
sales by the Underwriters to exceed 5% of the shares being offered hereby.
 
  ONYX, its officers and directors and certain other shareholders have agreed
that they will not offer, sell, contract to sell, announce their intention to
sell, pledge or otherwise dispose of, directly or indirectly, or file with the
Commission a registration statement under the Securities Act relating to, any
additional shares of common stock or securities convertible into or
exchangeable or exercisable for any shares of ONYX without
 
                                       61
<PAGE>
 
the prior written consent of Credit Suisse First Boston Corporation for a
period of 180 days after the date of this prospectus, except in the case of
ONYX issuances pursuant to the exercise of employee stock options outstanding
on the date hereof.
 
  Of the     shares of common stock to be sold in this offering, the
Underwriters have reserved for sale, at the price to public set forth on the
cover page of this prospectus, up to     shares as follows: (1) at the
Company's request, up to     shares for the Company's directors, officers,
employees and business associates and (2) up to an additional     shares for
the Preferred Shareholders in connection with a preexisting contractual right
between the Company and the Preferred Shareholders. See "Certain Transactions"
and "Principal Shareholders." As a result, the number of shares of common stock
available for sale to the general public will be reduced to the extent such
persons purchase the reserved shares. The Underwriters will offer to the
general public (on the same basis as the other shares to be sold in this
offering) any reserved shares that are not so purchased.
 
  ONYX has agreed to indemnify the Underwriters against certain liabilities,
including civil liabilities under the Securities Act, or to contribute to
payments which the Underwriters may be required to make in respect thereof.
 
  We have applied to list the shares of common stock on the Nasdaq National
Market.
 
  Prior to this offering, there has been no public market for the common stock.
The initial public offering price will be determined by negotiation between
ONYX and the Representatives. The principal factors to be considered in
determining the public offering price include: the information set forth in
this prospectus and otherwise available to the Representatives; the history and
the prospects for the industry in which ONYX will compete; the ability of
ONYX's management; the prospects for future earnings of ONYX; the present state
of ONYX's development and its current financial condition; the general
condition of the securities markets at the time of this offering; and the
recent market prices of, and the demand for, publicly traded common stock of
generally comparable companies.
 
  The Representatives, on behalf of the Underwriters, may engage in over-
allotment, stabilizing transactions, syndicate covering transactions and
penalty bids in accordance with Regulation M under the Exchange Act. Over-
allotment involves syndicate sales in excess of the offering size, which
creates a syndicate short position. Stabilizing transactions permit bids to
purchase the underlying security so long as the stabilizing bids do not exceed
a specified maximum. Syndicate covering transactions involve purchases of the
securities in the open market after the distribution has been completed in
order to cover syndicate short positions. Penalty bids permit the
Representatives to reclaim a selling concession from a syndicate member when
the securities originally sold by such syndicate member are purchased in a
syndicate covering transaction to cover syndicate short positions. Such
stabilizing transactions, syndicate covering transactions and penalty bids may
cause the price of the securities to be higher than it would otherwise be in
the absence of such transactions. These transactions may be effected on the
Nasdaq National Market or otherwise and, if commenced, may be discontinued at
any time.
 
                          NOTICE TO CANADIAN RESIDENTS
 
RESALE RESTRICTIONS
 
  The distribution of the common stock in Canada is being made only on a
private placement basis exempt from the requirement that ONYX 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
pursuant to 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 ONYX and the dealer from whom such purchase
confirmation is received that (1) such purchaser is entitled under applicable
provincial securities laws to purchase such common stock without the benefit of
a prospectus qualified under such securities laws, (2) where required by law,
such purchaser is purchasing as principal and not as agent, and (3) such
purchaser has reviewed the text above 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
section 32 of the Regulation under the Securities Act (Ontario). 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

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors
Onyx Software Corporation
 
  We have audited the accompanying consolidated balance sheets of ONYX Software
Corporation as of December 31, 1996 and 1997 and September 30, 1998, and the
related consolidated statements of operations, shareholders' equity, and cash
flows for each of the three years in the period ended December 31, 1997 and the
nine months ended September 30, 1998. 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 generally accepted auditing
standards. 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 financial statements referred to above present fairly, in
all material respects, the consolidated financial position of ONYX Software
Corporation at December 31, 1996 and 1997 and September 30, 1998, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1997 and the nine months ended
September 30, 1998, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1997 IS UNAUDITED)
 
1. DESCRIPTION OF THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 Description of the Company
 
  ONYX Software Corporation and subsidiaries (Company), is a leading provider
of Enterprise Relationship Management (ERM) solutions. The ONYX ERM solution
automates the key functions that enable enterprises to more effectively
acquire, manage and retain customers, partners and other relationships. The
majority of the Company's revenues are from the ONYX Customer Center product
family. The Company was incorporated in the State of Washington on February 13,
1994 under the name "Renaissance Software, Inc." and maintains its headquarters
in Bellevue, Washington.
 
  Operating results for the nine months ended September 30, 1998 are not
necessarily indicative of results that may be expected for the entire year.
 
 Principles of Consolidation
 
  The consolidated financial statements include the accounts of the Company and
its foreign subsidiaries. All intercompany accounts and transactions have been
eliminated in consolidation.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions
that affect amounts reported in the financial statements. Changes in these
estimates and assumptions may have a material impact on the financial
statements. The Company has used estimates in determining certain provisions,
including uncollectible trade accounts receivable, useful lives for fixed
assets and intangibles, and tax liabilities.
 
 Unaudited Interim Financial Information
 
  The financial information for the nine months ended September 30, 1997 is
unaudited but includes all adjustments (consisting only of normal recurring
adjustments) that the Company considers necessary for a fair presentation of
its financial position at such date and its operating results and cash flows
for that period.
 
 Revenue Recognition
 
  Statement of Position 97-2, Software Revenue Recognition (SOP 97-2), was
issued in October 1997 by the American Institute of Certified Public
Accountants and was amended by Statement of Position 98-4 (SOP 98-4). The
Company adopted SOP 97-2 effective January 1, 1998. Based upon their
interpretation of SOP 97-2 and SOP 98-4, the Company believes their current
revenue recognition policies and practices are consistent with SOP 97-2 and SOP
98-4. However, full implementation guidelines for this standard have not yet
been issued. Once available, such implementation guidance could lead to
unanticipated changes in current revenue accounting practices, and such changes
could materially adversely affect the Company's future revenues and earnings.
 
  The Company generates revenues through two sources: (i) software license
revenues and (ii) service revenues. Software license revenues are generated
from licensing the rights to use the Company's products directly to end-users
and indirectly through sublicense fees from resellers and, to a lesser extent,
through third-party products the Company distributes. Service revenues are
generated from sales of post-contract support, consulting and training services
performed for customers that license the Company's products.

                           ONYX SOFTWARE CORPORATION
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1997 IS UNAUDITED)
 
 
  Revenues from software license agreements are recognized upon delivery of
software if persuasive evidence of an arrangement exists, collection is
probable, the fee is fixed or determinable, and vendor-specific objective
evidence exists to allocate the total fee to elements of the arrangement.
Elements included in multiple element arrangements could consist of software
products, upgrades, enhancements, customer support services, or consulting
services. If an acceptance period is required, revenues are recognized upon the
earlier of customer acceptance or the expiration of the acceptance period. The
Company enters into reseller arrangements that typically provide for sublicense
fees based on a percentage of list price. Sublicense fees are generally
recognized as reported by the reseller upon relicensing of the Company's
products to end-users.
 
  Revenues from customer support services are recognized ratably over the term
of the contract, typically one year. Consulting revenues are primarily related
to implementation services performed on a time-and-materials basis under
separate service arrangements related to the installation of the Company's
software products. Revenues from consulting and training services are
recognized as services are performed. If a transaction includes both license
and service elements, license fee revenues are recognized on shipment of the
software, provided services do not include significant customization or
modification of the base product, and the payment terms for licenses are not
subject to acceptance criteria. In cases where license fee payments are
contingent on the acceptance of services, the Company defers recognition of
revenues from both the license and the service elements until the acceptance
criteria are met.
 
 Cash Equivalents
 
The Company considers all highly liquid investments with a maturity of three
months or less at purchase to be cash equivalents. The Company's cash
equivalents consist of banker's acceptances with a maturity of three months or
less and money market funds.
 
 Fair Values of Financial Instruments
 
  At September 30, 1998, the Company has the following financial instruments:
cash and cash equivalents, accounts receivable, accounts payable, accrued
liabilities, capital lease obligations and longterm debt. The carrying value of
cash and cash equivalents, accounts receivable, accounts payable and accrued
liabilities approximates their fair value based on the liquidity of these
financial instruments or based on their short-term nature. The carrying value
of capital lease obligations approximates fair value based on the market
interest rates available to the Company for debt of similar risk and
maturities. The carrying value of long-term debt is $1.1 million; the estimated
fair value of these obligations is $1.0 million based on the market interest
rates available to the Company for debt of similar risk and maturities.
 
 Property and Equipment
 
  Property and equipment is stated at cost less accumulated depreciation.
Depreciation and amortization is provided using the straight-line method over
the estimated useful lives of the related assets (or over the lease term if it
is shorter for leasehold improvements), which range from two to seven years.
Leasehold improvements are amortized over the shorter of the lease term or
estimated useful life.
 
 Purchased Technology and Goodwill
 
  Purchased technology represents software source code and software licenses
acquired from third parties. Amortization of purchased technology is provided
on a product-by-product basis over the estimated economic
 
                                      F-8

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1997 IS UNAUDITED)
 
life of the software, generally three to five years, using the straight-line
method. Unamortized capitalized costs determined to be in excess of the net
realizable value of a product are expensed at the date of such determination.
 
  Goodwill represents the excess of the purchase price over the fair value of
identifiable tangible and intangible assets acquired and is amortized using the
straight-line method over its estimated life of five years. Adjustments to the
carrying value of goodwill are made if the sum of expected future net cash
flows from the business acquired is less than book value.
 
 Research and Development
 
  Research and development costs, which consist primarily of software
development costs, are expensed as incurred. Financial accounting standards
provide for the capitalization of certain software development costs after
technological feasibility of the software is established. Under the Company's
current practice of developing new products and enhancements, the technological
feasibility of the underlying software is not established until substantially
all product development is complete, including the development of a working
model. No such costs have been capitalized because the impact of capitalizing
such costs would not be material.
 
 Concentration of Credit Risk and Major Customers
 
  Financial instruments that potentially subject the Company to a concentration
of credit risk consist principally of accounts receivable. The Company's
customer base is dispersed across many different geographic areas throughout
North America, Europe, Asia Pacific and Latin America and consists of companies
in a variety of industries. During 1995, one customer accounted for 15% of
total revenues. During 1996, 1997 and for the nine months ended September 30,
1997 and 1998, no single customer accounted for 10% or more of total revenues.
The Company does not require collateral or other security to support credit
sales, but provides an allowance for bad debts based on historical experience
and specifically identified risks.
 
 Foreign Currency Translation
 
  The functional currency of the Company's foreign subsidiaries is the local
currency in the country in which the subsidiary is located. Assets and
liabilities denominated in foreign currencies are translated to U.S. dollars at
the exchange rate in effect on the balance sheet date. Revenues and expenses
are translated at the average rates of exchange prevailing during the year. The
translation adjustment resulting from this process is shown within accumulated
other comprehensive income (loss) as a component of shareholders' equity. Gains
and losses on foreign currency transactions are included in the consolidated
statement of operations as incurred. To date, gains and losses on foreign
currency transactions have not been significant.
 
 Income Taxes
 
  The Company accounts for income taxes under the liability method. Under the
liability method, deferred tax assets and liabilities are determined based on
differences between financial reporting and tax bases of assets and liabilities
and are measured using the enacted tax rates and laws that will be in effect
when the differences are expected to reverse. Valuation allowances are
established, when necessary, to reduce deferred tax assets to the amounts
expected to be realized.

    (INFORMATION FOR THE NINE MONTHS ENDED SEPTEMBER 30, 1997 IS UNAUDITED)
 
 
 Stock-Based Compensation
 
  The Company has elected to follow Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees (APB No. 25), and related
interpretations, in accounting for its employee stock options rather than the
alternative fair value accounting allowed by Statement of Financial Accounting
Standards No. 123, Accounting for Stock-Based Compensation (SFAS No. 123). APB
No. 25 provides that the compensation expense relative to the Company's
employee stock options is measured based on the intrinsic value of the stock
option. SFAS No. 123 requires companies that continue to follow APB No. 25 to
provide a pro forma disclosure of the impact of applying the fair value method
of SFAS No. 123 (refer to Note 7).
 
 Advertising
 
  Advertising costs are expensed as incurred. Advertising expense was $170,000,
$704,000, and $1.6 million during the years ended December 31, 1995, 1996,
1997, respectively, and $1.0 million and $1.2 million for the nine months
ending September 30, 1997 and 1998, respectively.
 
 Earnings Per Share and Pro Forma Earnings Per Share
 
  Basic earnings per share is computed by dividing net income (loss) available
to common shareholders by the weighted average number of common shares
outstanding for the period. Diluted earnings per share reflects the potential
dilution of securities by including other common stock equivalents, including
stock options and convertible preferred stock, in the weighted average number
of common shares outstanding for a period, if dilutive.
 
  Pro forma earnings per share is computed by dividing net income (loss) by the
weighted average number of common shares outstanding and the weighted average
redeemable convertible preferred stock outstanding as if such shares were
converted into common stock at the time of issuance.
 
 Other Comprehensive Income
 
  In June 1997, the FASB issued SFAS No. 130, Reporting Comprehensive Income
(SFAS No. 130), which establishes standards for reporting and display of
comprehensive income and its components in the financial statements. The only
item of other comprehensive income (loss) which the Company currently reports
is foreign currency translation adjustments. There was no significant
difference between net income (loss) as reported versus other comprehensive
income (loss).
 
 Business Segments
 
  In June 1997, the FASB issued SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information (SFAS No. 131), which establishes standards
for reporting information about operating segments in annual financial
statements. It also establishes standards for related disclosures about
products and services, geographic areas and major customers. Information
related to SFAS No. 131 is contained in Note 11.
 
 Derivatives
 
  In June 1998, the FASB issued SFAS No. 133, Accounting for Derivatives and
Hedging Activities (SFAS No. 133), which establishes accounting and reporting
standards for derivative instruments, including certain derivative instruments
embedded in other contracts (collectively referred to as derivatives), and for
hedging activities. Because the Company has never used nor currently intends to
use derivatives, management does not anticipate that the adoption of the new
Statement will have a significant effect on earnings or the financial position
of the Company.

2. ACQUISITION
 
  On September 14, 1998, the Company acquired EnCyc, Inc. (EnCyc), a privately-
held marketing encyclopedia software developer. In exchange for all the
outstanding shares of EnCyc, the Company issued 233,333 shares of its common
stock, paid $500,000 to EnCyc shareholders, and liquidated $250,000 of EnCyc's
existing long-term debt. In addition, in connection with the acquisition, the
Company issued options to EnCyc employees to purchase up to 75,000 shares of
common stock. These options have been treated as part of the purchase price,
resulting in a total purchase price of $2.3 million, including direct costs of
the acquisition. The acquisition was accounted for using the purchase method of
accounting, and, accordingly, the results of EnCyc's operations are included in
the Company's condensed consolidated financial statements from the date of
acquisition.
 
  A summary of the purchase price for the acquisition is as follows (in

  To determine the value of the developed technology, the expected future cash
flows of the existing technology products were discounted, taking into account
risks related to the characteristics and applications of each product, existing
and future markets, and assessments of the life cycle stage of each product.
Based on this analysis, the existing technology that had reached technological
feasibility was capitalized. Amounts attributable to purchased technology and
goodwill will be amortized over their estimated useful life of five years on a
straight-line basis.

September 30, 1998, respectively.
 
4. LINE OF CREDIT
 
 Accounts Receivable Line of Credit
 
  In August 1998, the Company entered into a revolving credit agreement with a
financial institution. The agreement allows the Company to borrow up to $8.0
million, with maximum borrowings not to exceed 80% of eligible receivables as
defined by the agreement. Interest on borrowings is, at the Company's
discretion, at the lender's prime rate or LIBOR plus 2.0%. Among other
provisions, the Company is required to maintain certain financial covenants,
and the agreement restricts the payment of dividends. The line of credit
agreement expires in June 2000. At September 30, 1998, there were no borrowings
outstanding under this credit facility.
 
 Equipment Term Loan Facility
 
  In August 1998, the Company entered into an agreement with a financial
institution providing a $3.0 million term loan facility, with maximum
borrowings not to exceed invoice amounts for equipment purchased after June 1,
1998, for the purpose of financing new capital equipment purchases. Interest on
borrowings is at the lender's prime rate plus 0.25%. The facility provides for
a twelve-month advance period with monthly payments of interest only, followed
by 36 monthly payments of principal plus interest. Among other provisions, the
Company is required to maintain certain financial covenants, and the agreement
restricts the payment of dividends. The equipment term loan facility expires in
August 2002. At September 30, 1998, there were no borrowings outstanding under
this credit facility.
 
  Both credit facilities are cross-collateralized by liens against accounts
receivable and specific assets financed by lender, with a negative pledge on
other assets. The Company was in compliance with all financial covenants of the
credit facility at September 30, 1998.

  Rental expense was approximately $46,000, $232,000, and $1.1 million in 1995,
1996, and 1997 and $701,000 and $1.7 million for the nine months ending
September 30, 1997 and 1998, respectively.
 
  In June 1998, the Company signed a seven-year lease for a new corporate
headquarters in Bellevue, Washington, which is expected to commence July 1999.
The minimum lease payments associated with this lease are included in the
commitments above. The Company has the option to extend the lease for two
additional three-year terms. The Company must provide a $750,000 letter of
credit as security for the lease. If certain working capital requirements are
not met on the commencement date, the Company must provide an additional
$250,000 letter of credit. The letter of credit may be reduced annually by
specified amounts in the lease agreement upon the Company's achieving certain
economic goals. At September 30, 1998, there were no letters of credit
outstanding.
 
 Purchased Technology Obligation
 
  In June 1998, the Company entered into a non-cancelable agreement with a
third party software developer to license certain technology which will be
embedded in a future release of the Company's core product. The agreement calls
for eight quarterly payments of $156,000 totaling $1.25 million through January
2000. The initial cost of this technology of $1.25 million has been recorded as
purchased technology and as long-term debt ($625,000 as a current liability) in
the accompanying balance sheet. In addition to the installment

payments, the agreement calls for per user royalty payments. There are no
minimum per user royalty commitments in connection with this agreement.
 
  Upon release of the product embedded with the third party technology, the
intangible will be expensed on the higher of a per user basis over the
projected product life or straight-line amortization of two years from date of
release.
 
 Other Third-Party License Agreements
 
  The Company has entered into various agreements that allow the Company to
incorporate licensed technology into its products or that allow the Company the
right to sell separately the licensed technology. The Company incurs royalty
fees under these agreements that are based on a predetermined fee per license
sold. Royalty costs incurred under these agreements are recognized as products
are licensed and are included in cost of license revenues. These amounts
totaled $0, $5,000, and $156,000 in 1995, 1996 and 1997 and $64,000 and
$470,000 for the nine months ended September 30, 1997 and 1998. As of September
30, 1998, future commitments under these arrangements were not significant.
 
 Contingencies
 
  The Company is subject to legal proceedings and claims in the ordinary course
of business. Onyx Computers, Inc. has filed a lawsuit against the Company
alleging trademark infringement in Canada. The Company is attempting to
negotiate a settlement, but any amount of loss is not estimable and no accrual
has been recorded in the financial statements. An adverse outcome could have a
material adverse effect on the Company's financial position, liquidity, and
results of operations.

of the majority of the preferred shareholders, as specified in the Articles. In
the event of liquidation, the holders of Series A have preferential rights over
common shareholders to liquidation payments at the original purchase price,
plus declared but unpaid dividends. The Company has not declared any Series A
dividends to date. Holders of Series A have redemption rights on or after

  Under the terms of the agreement, Series B shareholders have rights in
preference to, but otherwise similar to those of Series A shareholders,
including dividends of $0.635 (10%) per share per annum, when and if declared.
Series B shareholders also have redemption rights on or after February 1, 2000
that may require the Company to redeem their stock at the original purchase
price, plus declared but unpaid dividends, plus simple interest at 10% per
annum from the date of original issuance of such shares. The Company has not
declared any Series B dividends to date.
 
7. SHAREHOLDERS' EQUITY
 
 Notes Receivable from Officers
 
  In July 1998, certain officers exercised options to purchase 1,300,000 shares
of common stock and paid the exercise price by issuing promissory notes to the
Company totaling $210,000. These notes, which have been offset against common
stock for financial statement presentation, are due in July 2001 and bear
interest at 5.39%, payable annually. These notes and the interest thereon are
full recourse.

Plan (the Plan), the Board of Directors may grant incentive and nonqualified
stock options to employees, officers, directors, agents, consultants, and
independent contractors of the Company. There were 5,000,000 shares of common
stock reserved under the 1994 Plan. Generally, the Company grants stock options
with exercise prices equal to the fair market value of the common stock on the
date of grant, as determined by the Company's Board of Directors. Options
generally vest over a four and one-half year period; 25% are exercisable after
18 months, with 12.5% exercisable every six months thereafter. In December
1997, the Board of Directors made a special grant of 141,600 options to certain
key employees that vest 1.67% after 18 months, and an additional 1.67% at the
end of each month thereafter, with the result that 100% of the options are
vested six and one-half years

from the date of grant. Options generally expire ten years from the date of
grant. On October 23, 1998, the Board of Directors of ONYX suspended the 1994
Plan and determined that no further grants shall be made pursuant to the 1994
Plan (see Note 12).
 
  Under APB No. 25, because the exercise price of the Company's employee stock
options generally equals the fair value of the underlying stock on the date of
grant, no compensation expense is recognized. Deferred compensation expense of
$140,000 and $98,000 was recorded in December 1997 and during 1998,
respectively, for those situations where the exercise price of an option was
lower than the deemed fair value for financial reporting purposes of the
underlying common stock. The deferred compensation is being amortized over the
vesting period of the underlying options.
 
  Had the stock compensation expense for the Company's stock option plan been
determined based on the minimum value model, the Company's net income (loss)
would have been adjusted to these pro forma amounts:

  For purposes of the pro forma disclosures, the estimated weighted average
fair value of the options granted, estimated to be $0.07, $0.05, $0.15 and
$0.69 at December 31, 1995, 1996, and 1997 and September 30, 1998,
respectively, is amortized to expense over the options' vesting period.
Compensation expense recognized in providing pro forma disclosures may not be
representative of the effects on pro forma earnings for future years because
the amounts above include only the amortization for the fair value of 1995,
1996, 1997 and the nine months ended September 30, 1998 grants.

    1998 exercise of stock options in exchange for promissory notes to the
    Company are only considered in the calculation of diluted earnings per
    share.
 
** Excluded from the computation of diluted earnings per share given the
   effects are antidilutive. Outstanding stock options to purchase 799,764 and
   3,831,076 shares of common stock at December 31, 1996 and 1997,
   respectively, and 3,198,402 and 4,652,127 shares of common stock at
   September 30, 1997 and 1998, respectively, were excluded from the
   computation of diluted earnings per share because their effect was anti-
   dilutive (see Note 7 for additional stock option information).

  At September 30, 1998, the Company had a domestic net operating loss and
research and development carryforwards of $6.1 million and $453,000,
respectively, which begin to expire in 2017. Utilization of these carryforwards
depends on the recognition of future taxable income. The Company's ability to
utilize net operating loss carryforwards may be limited in the event that a
change in ownership, as defined in the Internal Revenue Code, occurs in the
future. To the extent that any single-year loss is not utilized to the full
amount of the limitation, such unused loss is carried forward to subsequent
years until the earlier of its utilization or the expiration of the relevant
carryforward period.

  Deferred tax assets reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components
of the Company's deferred tax assets and liabilities are as follows:

  Since the Company's utilization of these deferred tax assets is dependent on
future profits, which are not assured, a valuation allowance equal to the net
deferred tax assets has been provided. The valuation allowance for deferred tax
assets increased $315,000 and $2.3 million during the year ended December 31,
1997 and the nine months ended September 30, 1998, respectively.
 
10. EMPLOYEE BENEFIT PLAN
 
  The Company maintains a profit-sharing retirement plan for eligible employees
under the provisions of Internal Revenue Code Section 401(k). Participants may
defer up to 15% of their annual compensation on a pretax basis, subject to
maximum limits on contributions prescribed by law. Contributions by the Company
are at the discretion of the Board of Directors. No discretionary contributions
have been made by the Company to date.

12. SUBSEQUENT EVENTS
 
 Initial Public Offering
 
  On December 4, 1998, the Board of Directors authorized management to file a
registration statement with the Securities and Exchange Commission to permit
the Company to offer its common stock to the public. On December 4, 1998, the
Board also approved, subject to shareholder approval, the amendment of the
Company's Articles and Bylaws, which included, among other things, an increase
in the capitalization of the Company to 40,000,000 shares of common stock and
10,000,000 shares of preferred stock, each with a par value of $0.01 per share,
effective upon the filing with the Secretary of State of Washington, and an
increase in the number of shares of common stock issuable upon conversion of
the Series B Redeemable Convertible Preferred Stock. The accompanying financial
statements reflect the increase in the capitalization of the Company. If the
offering is consummated under terms presently anticipated, each outstanding
share of redeemable convertible preferred stock will convert into 3,533,925
shares of common stock. Unaudited pro forma shareholders' equity reflects the
assumed conversion of the redeemable convertible preferred stock outstanding at
September 30, 1998 into common stock.
 
 1998 Stock Incentive Compensation Plan
 
  On October 23, 1998, the Board adopted the 1998 Stock Incentive Compensation
Plan (1998 Plan), which was approved by the Company's shareholders on November
24, 1998. The 1998 Plan provides for both stock options and restricted stock
awards to employees, officers, directors, agents, advisors, consultants and
independent contractors of the Company. Options granted under the 1998 plan
generally vest and become exercisable 25% 18 months after the date of grant,
and additional 12.5% shall vest at the end of each six-month period thereafter,
with the result that 100% of the options are vested four and one-half years
from the initiation date. As of November 30, 1998, the Company has reserved a
total of (i) 4,907,124 shares of common stock

(1,518,872 shares of common stock from the 1998 Plan plus 3,388,252 shares
issuable upon exercise of options that were outstanding but unexercised under
the 1994 Plan), and (ii) an annual increase to be added on the first day of
each fiscal year beginning in 2000 equal to the lesser of 1,675,763 shares or
5% of the average common shares outstanding used to calculate fully diluted
earnings per share, as reported for the preceding year. Any shares returned to
the 1994 Plan as a result of termination of options or repurchase of shares by
the Company become available for future grant from the 1998 Plan. In
conjunction with the adoption of the 1998 Plan, the Company granted options to
acquire 66,700 shares of common stock at an exercise price of $9.00 per share
to employees from the 1994 Plan's remaining stock option pool, and options to
acquire 16,200 shares of common stock at an exercise price of $9.00 per share
to employees from the 1998 Plan.
 
 1998 Employee Stock Purchase Plan
 
  On December 4, 1998, the Board approved the 1998 Employee Stock Purchase Plan
(the ESPP), subject to approval by the Company's shareholders. If the ESPP is
approved by the shareholders, the Company will implement it upon the
effectiveness of the initial public offering. The ESPP permits eligible
employees of ONYX and its subsidiaries to purchase common stock through payroll
deductions of up to 10% of their compensation. Under the ESPP, no employee may
purchase common stock worth more than $25,000 in any calendar year, valued as
of the first day of each offering period. In addition, owners of 5% or more of
ONYX's or a subsidiary's common stock may not participate in the ESPP. The
Company authorized the issuance under the ESPP of a total of 500,000 shares of
common stock, plus an automatic annual increase, to be added on the first day
of the fiscal year beginning in 2000, equal to the lesser of (a) 200,000 shares
and (b) 1.2% of the average common shares outstanding as used to calculate
fully diluted earnings per share as reported in the Annual Report for the
preceding year, or a lesser amount determined by the Board of Directors. Any
shares from increases in previous years that are not actually issued shall be
added to the aggregate number of shares available for issuance under the ESPP.
 
  We will implement the ESPP with six-month offering periods. The first
offering period will commence on the effectiveness of this offering. Subsequent
offering periods will begin on each January 1 and July 1. The price of the
common stock purchased under the ESPP will be the lesser of 85% of the fair
market value on the first day of an offering period and 85% of the fair market
value on the last day of an offering period, except that the purchase price for
the first offering period will be equal to the lesser of 100% of the initial
public offering price of the common stock and 85% of the fair market value on
June 30, 1999. The ESPP does not have a fixed expiration date, but ONYX's Board
of Directors may terminate it at any time. The Company has not yet issued any
shares of common stock under the ESPP.

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 court to award, or a corporation's board of
directors to grant, indemnification to directors and officers on terms
sufficiently broad to permit indemnification under certain circumstances for
liabilities arising under the Securities Act of 1933, as amended (the
"Securities Act"). Section 10 of the registrant's Restated Bylaws (Exhibit 3.2
hereto) provides for indemnification of the registrant's directors, officers,
employees and agents to the maximum extent permitted by Washington law. The
directors and officers of the registrant also may be indemnified against
liability they may incur for serving in that capacity pursuant to a liability
insurance policy maintained by the registrant for such purpose.
 
  Section 23B.08.320 of the WBCA authorizes a corporation to limit a director's
liability to the corporation or its shareholders for monetary damages for acts
or omissions as a director, except in certain circumstances involving
intentional misconduct, knowing violations of law or illegal corporate loans or
distributions, or any transaction from which the director personally receives a
benefit in money, property or services to which the director is not legally
entitled. Section 5.2 of the registrant's Fourth Amended and Restated Articles
of Incorporation (Exhibit 3.1 hereto) contains provisions implementing, to the
fullest extent permitted by Washington law, such limitations on a director's
liability to the registrant and its shareholders.
 
  The registrant has entered into certain indemnification agreements with its
officers and directors, the form of which is attached as Exhibit 10.11 to this
Registration Statement and incorporated herein by reference. The
indemnification agreements provide the registrant's officers and directors with
indemnification to the maximum extent permitted by the WBCA.
 
  The Underwriting Agreement (Exhibit 1.1 hereto) provides for indemnification
by the Underwriters of the registrant and its executive officers and directors,
and by the registrant of the Underwriters, for certain liabilities, including
liabilities arising under the Securities Act, in connection with matters

  Series A Preferred Stock, or an aggregate of $3,000,233. The foregoing

  involve a public offering.
 
    2. On March 31, 1997, the registrant issued 1,259,843 shares of Series B
  Preferred Stock, which are convertible into 1,359,843 shares of common

  registration under the Securities Act pursuant to Section 4(2) thereof on
  the basis that the transactions did not involve a public offering.
 
    3. From December 1995 through November 1998, the registrant granted stock
  options to purchase 5,725,660 shares of common stock, with exercise prices
  ranging from $.20 to $9.00 per share, to employees, consultants and
  directors pursuant to its Amended and Restated 1994 Combined Incentive and
  Nonqualified Stock Option Plan. Of these options, options for 744,532
  shares have been canceled without being exercised, options for 1,592,876
  shares have been exercised and options for 3,388,252 shares remain
  outstanding. From October 23, 1998 through November 30, 1998, the
  registrant granted stock options to purchase 16,200 shares of the
  registrant's common stock, with an exercise price of $9.00 per share, to
  employees and consultants pursuant to its 1998 Stock Incentive Compensation
  Plan. Of these options, none have been canceled without being exercised,
  none have been exercised and options for 16,200 shares remain outstanding.
 
    4. In September 1998, pursuant to an Agreement and Plan of Merger by and
  among the registrant, EnCyc Acquisition, Inc., EnCyc, Inc. ("EnCyc") and
  the shareholders of EnCyc, the registrant issued 233,333 shares of common
  stock in connection with the registrant's acquisition of all the issued and
  outstanding shares of EnCyc. The form of the transaction was a merger,
  whereby a wholly owned subsidiary of the registrant was merged with and
  into EnCyc. The recipients of the common stock were the former shareholders
  of EnCyc. The issuance of these securities was exempt from registration
  under the Securities Act pursuant to Section 4(2) thereof on the basis that
  the transaction did not involve a public offering.
 
  The sales and issuances of these securities were exempt from registration
under the Securities Act pursuant to Rule 701 promulgated thereunder on the
basis that these options were offered and sold either pursuant to a written
compensatory benefit plan or pursuant to written contracts relating to
consideration, as provided by Rule 701, or pursuant to Section 4(2) of the
Securities Act on the basis that the transactions did not involve a public
offering.

    Section II--Valuation and Qualifying Accounts
 
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 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
 
                                      II-3
<PAGE>
 
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 question of 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.
 
  The undersigned registrant hereby undertakes to provide to the Underwriters,
at the closing specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.
 
  The undersigned registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act shall be deemed to be part of this
  Registration Statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities
  Act, each post-effective amendment that contains a form of prospectus 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.

                                       OF

                           ONYX SOFTWARE CORPORATION

     Pursuant to the provisions of RCW 23B.10.070 of the Washington Business
Corporation Act, Onyx Software Corporation, a Washington corporation, hereby
restates its Articles of Incorporation as now and heretofore amended:

1.  NAME

     The name of the Company is Onyx Software Corporation (the "COMPANY").

2.  SHARES

     2.1.  AUTHORIZED CAPITAL

     The Company is authorized to issue 40,000,000 shares, consisting of
30,000,000 shares designated as common stock ("COMMON STOCK") and 10,000,000
shares designated as preferred stock ("PREFERRED STOCK"), the par value of each
of which is $0.01.  Common Stock is subject to the rights and preferences of
Preferred Stock as hereinafter set forth.  Except to the extent such rights are
granted to Preferred Stock or one or more series thereof, holders of shares of
Common Stock shall have unlimited voting rights and are entitled to receive the
net assets of the Company upon dissolution.

     2.2.  ISSUANCE OF PREFERRED STOCK IN SERIES

     The Company's Board of Directors (the "BOARD") may designate one or more
series of Preferred Stock, and the designation and number of shares within each
series, and shall determine the preferences, limitations, and relative rights of
any shares of Preferred Stock, or of any series of Preferred Stock, before
issuance of any shares of that class or series.  Preferred Stock, or any series
thereof, may have rights which are identical to those of Common Stock.  Subject
to compliance with the provisions of any series of Preferred Stock, the Board is
also authorized to increase or decrease the number of shares of any series of
Preferred Stock prior or subsequent to the issue of that series, but not below
the number of shares of such series then outstanding.  In case the number of
shares of any series shall be so decreased, the shares constituting 

                                      -1-

<PAGE>
 
such decrease shall resume the status which they had prior to the adoption of
the resolution originally fixing the number of shares of such series.

     2.3.  DIVIDENDS

     The holders of shares of Preferred Stock shall be entitled to receive
dividends, out of the funds of the Company legally available therefor, at the
rate and at the time or times, whether cumulative or noncumulative, as may be
provided by the Board in designating a particular series of Preferred Stock.  If
such dividends on the Preferred Stock shall be cumulative, then if dividends
shall not have been paid, the deficiency shall be fully paid or the dividends
declared and set apart for payment at such rate, but without interest on
cumulative dividends, before any dividends on the Common Stock shall be paid or
declared and set apart for payment.  Shares of one class or series may be issued
as a share dividend in respect to shares of another class or series.

     2.4.  REDEMPTION

     Preferred Stock may be redeemable at such price, in such amount, and at
such time or times as may be provided by the Board in designating a particular
series of Preferred Stock.  In any event, such Preferred Stock may be
repurchased by the Company to the extent legally permissible.

     2.5.  LIQUIDATION

     In the event of any liquidation, dissolution, or winding up of the affairs
of the Company, whether voluntary or involuntary, then, before any distribution
shall be made to the holders of the Common Stock, the holders of the Preferred
Stock at the time outstanding shall be entitled to be paid the preferential
amount or amounts per share as may be provided by the Board in designating a
particular series of Preferred Stock and dividends accrued thereon to the date
of such payment.  The holders of the Preferred Stock shall not be entitled to
receive any distributive amounts upon the liquidation, dissolution, or winding
up of the affairs of the Company other than the distributive amounts referred to
in this section, unless otherwise provided by the Board in designating a
particular series of Preferred Stock.

     2.6.  CONVERSION

     Shares of Preferred Stock may be convertible into Common Stock of the
Company upon such terms and conditions, at such rate and subject to such
adjustments as may be provided by the Board in designating a particular series
of Preferred Stock.

                                      -2-

<PAGE>
 
     2.7.  VOTING RIGHTS

     Holders of Preferred Stock shall have such voting rights as may be provided
by the Board in designating a particular series of Preferred Stock.

     2.8.  PREFERRED STOCK DESIGNATIONS

     The Preferred Stock shall be divided into series, and 2,174,082 shares of
Preferred Stock are designated Series A Convertible Preferred Stock (the "SERIES
A STOCK") and 1,259,843 shares of Preferred Stock are designated Series B
Convertible Preferred Stock (the "SERIES B STOCK").  The rights, preferences,
restrictions and other matters relating to the Series A Stock and the Series B
Stock are set forth below.

          2.8.1.  DIVIDEND PREFERENCE

               2.8.1.1.  DIVIDEND RATE

          Subject to the rights and preferences of any series of Preferred Stock
that may rank senior to the Series A Stock and Series B Stock as to dividends
and may from time to time come into existence, holders of shares of Series A
Stock and holders of shares of Series B Stock, respectively, shall be entitled
to receive dividends, payable when, if and as declared by the Board out of funds
that are legally available therefor a noncumulative cash dividend per annum of
$.138 per share (as adjusted for any stock dividends, combinations or splits
with respect to such shares) and of $.635 per share (as adjusted for any stock
dividends, combinations or splits with respect to such shares), respectively, if
and when declared by the Board in its discretion.  Such dividend, if and so
declared, shall be paid at such time or times as shall be determined by the
Board.  No right shall accrue to holders of Series A Stock or Series B Stock by
reason of the fact that dividends on Series A Stock or Series B Stock are not
declared in any prior period.  No dividend may be paid on any shares of Series A
Stock or Series B Stock unless a pro rata dividend is paid on the Series B Stock
or Series A Stock, respectively.

               2.8.1.2.  LIMITATION ON OTHER DIVIDENDS

          So long as any shares of Series A Stock or shares of Series B Stock
shall remain outstanding, no dividend, whether in cash or property, shall be
paid or declared, nor shall any other distribution be made, on shares of Common
Stock or any shares of Preferred Stock having a preferential right to dividends
ranking junior to the rights of the Series A Stock, the Series B Stock or any
other series of Preferred Stock having a right to dividends ranking equal to
that of the Series A Stock and Series B Stock ("JUNIOR DIVIDEND STOCK") during
any fiscal year of the corporation 

                                      -3-

<PAGE>
 
until dividends in the total amount payable at the rates of $.138 per share and
$.635 per share (as adjusted for any stock dividends, combinations or splits
with respect to such shares) on the Series A Stock and Series B Stock,
respectively, shall have been paid or set apart during that fiscal year and all
declared and unpaid dividends on the Series A Stock, Series B Stock and such
parity Preferred Stock shall have been paid.

               2.8.1.3.  DIVIDEND PARTICIPATION

          No cash dividends shall be declared on the Junior Dividend Stock
unless or until a cash dividend in an amount equal to or greater than the
dividend declared on the Junior Dividend Stock shall have been paid to, or
declared and a sum sufficient for the payment thereof set apart for the Series A
Stock, Series B Stock and any other series of Preferred Stock having a right to
dividends ranking equal to that of the Series A Stock and the Series B Stock.
For purposes of this provision, dividends shall be compared on an as-converted-
to-Common-Stock basis.

          2.8.2.  LIQUIDATION PREFERENCE

          Upon the voluntary or involuntary dissolution, liquidation or winding
up of the Company, the assets of the Company available for distribution to its
shareholders shall be distributed in the following order and amounts:

               2.8.2.1.  SENIOR LIQUIDATION PAYMENTS

          First, the holders, if any, of any outstanding shares of Preferred
Stock of the Company having a preferential right to liquidation payments ranking
senior to the rights of holders of Series A Stock or Series B Stock shall be
entitled to receive the full preferential amount per share held by them (the
"SENIOR LIQUIDATION AMOUNT").  If the assets of the Company available for such
distribution shall be insufficient to permit the payment of the full Senior
Liquidation Amount, then the assets of the Company available for distribution
shall be distributed ratably among the holders of the shares of such senior
preferred stock in the same proportions as the full Senior Liquidation Amount
each such holder would otherwise be entitled to receive bears to the total of
the full Senior Liquidation Amount that would otherwise be payable to all
holders of such senior preferred stock.

               2.8.2.2.  PARITY LIQUIDATION PAYMENTS

          If, upon completion of the distribution required by the prior
paragraph, assets available for distribution to shareholders remain in the
Company, the holders, if any, of any outstanding shares of preferred stock of
the Company having a preferential right to liquidation payments ranking equal to
the rights of the 

                                      -4-

<PAGE>
 
holders of Series A Stock or Series B Stock (the "PARITY SHARES") shall be
entitled to receive the liquidation payment specified for such shares held by
them (the "PARITY LIQUIDATION AMOUNT"), the holders of shares of Series A Stock
shall be entitled to receive the amount of $1.38 per share, plus any declared
and unpaid dividends, for each share of Series A Stock (the "SERIES A
LIQUIDATION AMOUNT ") and the holders of shares of Series B Stock shall be
entitled to receive the amount of $6.35 per share, plus any declared and unpaid
dividends, for each share of Series B Stock (the "SERIES B LIQUIDATION AMOUNT
"). The Parity Liquidation Amount, the Series A Liquidation Amount and the
Series B Liquidation Amount shall be adjusted for any Extraordinary Common Stock
Event (as defined below). If the assets of the Company available for such
distribution shall be insufficient to permit the payment in full of the Parity
Liquidation Amount, the Series A Liquidation Amount and the Series B Liquidation
Amount, then the assets of the Company available for distribution shall be
distributed ratably among the holders of Parity Shares, the holders of Series A
Stock and the holders of Series B Stock in the same proportions as the aggregate
of the Parity Liquidation Amount, Series A Liquidation Amount and Series B
Liquidation Amount that each such holder would otherwise be entitled to receive
bears to the total Parity Liquidation Amount, Series A Liquidation Amount and
Series B Liquidation Amount that would otherwise be payable to all such holders.

               2.8.2.3.  JUNIOR AND PARTICIPATING LIQUIDATION PAYMENTS

          Upon the completion of the distribution contemplated pursuant to the
foregoing two paragraphs, if assets remain in the Company, such remaining assets
shall be distributed ratably (on an as-converted-to-Common-Stock basis) to the
holders of Common Stock, the holders of Series A Stock, the holders of Series B
Stock and the holders of any other series of Preferred Stock that is entitled to
a ratable share in the residual assets of the Company.  Notwithstanding the
foregoing sentence, at such point as a holder of Series A Stock or Series B
Stock has received an aggregate amount pursuant to this Section 2.8 equal to two
and one-half times the respective Series A Liquidation Amount or Series B
Liquidation Amount, then such holder's participation in any distribution of
assets in respect of such Series A Stock or Series B Stock shall cease and any
remaining assets shall be distributed ratably to the holders of Common Stock and
the holders, if any, of any other series of Preferred Stock that is entitled to
share in the residual assets of the Company.

               2.8.2.4.  TREATMENT OF CONSOLIDATIONS, MERGERS AND SALES OF
                         ASSETS

          The sale of all or substantially all of the assets of the Company, or
the acquisition of the Company by another entity by means of merger,
consolidation, share exchange, reorganization or otherwise pursuant to which
shares of capital stock of the Company are converted into cash, securities or
other property of the acquiring entity or any of its affiliates shall be
regarded as a liquidation within the meaning of this Section 2.8.2; provided,
however, that each holder of Series A Stock, Series B Stock or other shares of
convertible Preferred Stock of the Company shall have the right to elect the
benefits of any applicable conversion provisions in lieu of receiving payment in
the event of the liquidation, dissolution or winding up of the Company pursuant
to this Section 2.8.2; provided, further, that this provision shall not apply if
the holders of voting capital stock of the Company immediately prior to such
merger, consolidation, share exchange, reorganization or sale of assets
beneficially own, directly or indirectly, a majority of the combined voting
power of the capital stock of the surviving entity resulting from such merger,
consolidation, share exchange or reorganization or the successor corporation in
any such sale of assets.

               In the event the requirements of this Section 2.8.2.4 are not
complied with, the Company shall forthwith either:

          (a) Cause the date of distribution to be postponed until such time as
the requirements of this Section 2.8.2.4 have been complied with; or

          (b) Cancel such transaction, in which event the rights, preferences
and privileges of the holders of Series A Stock and Series B Stock shall revert
to those as existed immediately prior to the liquidation event.

               2.8.2.5.  DISTRIBUTIONS OTHER THAN CASH

          Whenever the distribution provided for in this Section 2.8.2 shall be
payable in property other than cash, then the following provisions shall apply:

                    2.8.2.5.1.  SECURITIES DISTRIBUTIONS

          (a) Securities not subject to investment letter or other similar
restrictions on free marketability shall be valued as follows:

          (i) If traded on a securities exchange or the Nasdaq National Market,
the value shall be deemed to be the average of the closing 

                                      -6-

<PAGE>
 
prices of the securities on such exchange over the 30-day period ending three
business days prior to the date of distribution;

          (ii) If actively traded over-the-counter, the value shall be deemed to
be the average of the closing bid prices over the 30-day period ending three
days prior to the date of distribution; and

          (iii)  If there is no active public market, the value shall be the
fair market value thereof, as determined by the Board.

          (b) Securities subject to investment letter or other restrictions on
free marketability (other than restrictions arising solely by virtue of a
shareholder's status as an affiliate or former affiliate) shall be valued as
described above less an appropriate discount from market value, as determined by
the Board, to reflect the transfer restrictions.

                    2.8.2.5.2.  OTHER NONCASH DISTRIBUTIONS

          In the event of any other noncash distribution, the Board shall
promptly engage independent appraisers to determine the value of the assets to
be distributed.  The Company shall, upon receipt of such appraiser's valuation,
give prompt written notice to each holder of Preferred Stock of the appraiser's
valuation.

               2.8.2.6.  NOTICE OF LIQUIDATION TRANSACTION

          The Company shall give each record holder of Series A Stock or Series
B Stock written notice (the "Liquidation Notice") of an impending liquidation
transaction subject to this Section 2.8.2 not later than 20 days before any
meeting of the Company's shareholders called to approve the liquidation
transaction or 20 days before the closing of the liquidation transaction,
whichever is earlier, and shall also notify such holders in writing of the final
approval of such transaction.  The first of such notices shall describe the
material terms and conditions of the impending liquidation transaction and the
provisions of this Section 2.8.2.6, and the Company shall thereafter give such
holders prompt notice of any material changes.  The liquidation transaction
shall in no event take place sooner than 20 days after the Company has given the
first notice provided for herein or sooner than 10 days after the Company has
given notice of any material changes provided for herein; provided, however,
that such periods may be shortened upon the written consent of the holders of
Preferred Stock that are entitled to such notice rights or similar notice rights
and that represent at least a majority of the voting power of all then
outstanding shares of each series of Preferred Stock.

               2.8.2.7.  NO DEROGATION OF PROTECTIVE PROVISIONS

               The provisions of Section 2.8.2 are in addition to the protective
provisions of Section 2.8.6.

          2.8.3.  REDEMPTION

               2.8.3.1.  REDEMPTION OPTION

          The Company shall, upon receipt at any time on or after February 1,
2000 of the written request, respectively, of holders of not less than 60% of
the then outstanding Series A Stock or of holders of a majority of the then
outstanding Series B Stock, redeem any then unconverted shares of such series of
Preferred Stock.

               2.8.3.2.  NOTICE OF REDEMPTION REQUEST

          Upon receipt of a request for redemption under this Section 2.8.3, the
Company shall promptly mail a written notice that such request has been made (a
"REDEMPTION REQUEST NOTICE"), postage prepaid, to each holder of record of
Preferred Stock at the address last shown on the records of the Company, with a
copy of the Redemption Request Notice to each such holder sent by facsimile
transmission, by tested or otherwise authenticated telex or by any similar
electronic communication.  Within twenty days of the date of a Redemption
Request Notice, holders of the requisite percentage of any series of Preferred
Stock with redemption rights that are not subordinate to the redemption rights
of the series of Preferred Stock that requested redemption ("PARITY REDEMPTION
STOCK") may join in the redemption request.  For purposes of this Section 2.8.3,
Series A Stock and Series B Stock are, with respect to each other, Parity
Redemption Stock.  In the event that the applicable percentage of all series of
Parity Redemption Stock join in the original redemption request, the Company may
forgo issuance of a Redemption Request Notice.

               2.8.3.3.  NOTICE OF REDEMPTION DATES

          After the earlier of the twenty-day period described in Section
2.8.3.2 or, if all series of Parity Redemption Stock joined in the initial
redemption request, receipt by the Company of such initial redemption request
(the "REQUEST INITIATION DATE"), the Company shall promptly mail a written
notice (a "REDEMPTION NOTICE") to each holder of record (at the close of
business on the business day next preceding the day on which the Redemption
Notice is given) of shares of Parity Redemption Stock specifying the date in
each of three successive years following the Request Initiation Date (each a
"REDEMPTION DATE") as the dates 

                                      -8-

<PAGE>
 
on which one third of the shares of the then outstanding Parity Redemption Stock
as to which redemption has been requested will be redeemed. The first Redemption
Date shall be a business day that is at least 20 and not more than 90 days from
the Request Initiation Date and the second and third Redemption Dates shall be
the day that is one year and two years, respectively, from the first Redemption
Date; provided, however, if any such day is not a business day, the next
business day thereafter shall be the Redemption Date. The Redemption Notice
shall also specify the applicable redemption price for each series of Parity
Redemption Stock to be redeemed, the number of shares of each series of Parity
Redemption Stock anticipated by the Company to be redeemed from such holder on
each Redemption Date (assuming no conversion of any shares of Parity Redemption
Stock) and the place where redemption shall be made. The Company shall deliver
the Redemption Notice, postage prepaid, to each holder of record of Parity
Redemption Stock at the address last shown on the records of the Company, with a
copy of the Redemption Notice to each such holder sent by facsimile
transmission, by tested or otherwise authenticated telex or by any similar
electronic communication. No defect in the Redemption Notice or in the mailing
or publication thereof shall affect the validity of the redemption proceeding
with respect to the Company or any holder of Parity Redemption Stock except as
to any holder that has not received actual notice of the redemption.

               2.8.3.4.  REDEMPTION PRICE

          The redemption price per share of Series A Stock (the "SERIES A
REDEMPTION PRICE ") shall be $1.38, plus any declared but unpaid dividends
thereon, plus simple interest at 10% per annum from the date of original
issuance of such share of Series A Stock until such share is redeemed, all as
adjusted for any combinations, consolidations, stock distributions or stock
dividends with respect to any such shares.  The redemption price per share of
Series B Stock (the "SERIES B REDEMPTION PRICE ") shall be $6.35, plus any
declared but unpaid dividends thereon, plus simple interest at 10% per annum
from the date of original issuance of such share of Series B Stock, all as
adjusted for any combinations, consolidations, stock distributions or stock
dividends with respect to any such shares.  The Series A Redemption Price and
the Series B Redemption Price, together with the redemption price of any other
shares of Parity Redemption Stock, are collectively referred to in this Section
2.8.3.4 as the "REDEMPTION PRICE."

               2.8.3.5.  REDEMPTION OBLIGATION

     Subject to limitations imposed by law, the Company shall redeem on each
Redemption Date the number of shares of Parity Redemption Stock held by each
holder thereof determined by dividing (a) the aggregate number of shares of
Parity 

                                      -9-

<PAGE>
 
Redemption Stock held by such holder by (b) the number of remaining Redemption
Dates (including the Redemption Date to which such calculation applies) (such
obligation to redeem shares of Parity Redemption Stock being referred to herein
as a "REDEMPTION OBLIGATION"). If the funds of the Company legally available for
redemption of shares of Parity Redemption Stock on a Redemption Date are
insufficient to fulfill a Redemption Obligation and redeem the total number of
shares of Parity Redemption Stock to be redeemed on such Redemption Date, the
holders of such shares shall share ratably in any funds legally available for
redemption of such shares according to the respective amounts which would be
payable to them if the full number of shares to be redeemed on such Redemption
Date were actually redeemed, computed pro rata based on the aggregate Redemption
Price for the shares of Parity Redemption Stock held by such holder compared to
the aggregate Redemption Price for all the shares of Parity Redemption Stock to
be redeemed by the Company on the Redemption Date if the full number of shares
to be redeemed on such Redemption Date were actually redeemed (and the number of
shares of each series of Parity Redemption Stock to be redeemed from each holder
shall be computed pro rata based on the aggregate Redemption Price for the
shares of such series held by such holder compared to the aggregate Redemption
Price for all the shares of Parity Redemption Stock held by such holder).

               2.8.3.6.  SURRENDER OF STOCK

          On or after each Redemption Date, each holder of shares of Parity
Redemption Stock shall surrender the certificate or certificates evidencing
shares of Parity Redemption Stock to be redeemed to the Company at any place
designated for such surrender in the Redemption Notice and shall then be
entitled to receive payment in cash, by wire transfer or by bank-certified check
of the Redemption Price for each share of Parity Redemption Stock to be
redeemed.  If less than all of the shares represented by a share certificate are
to be redeemed, the Company shall issue a new certificate representing the
shares not redeemed.

               2.8.3.7.  FAILURE TO REDEEM

          If and so long as any Redemption Obligation shall not fully be
satisfied, (a) each holder of shares of Parity Redemption Stock as to which a
Redemption Obligation has not been satisfied shall be entitled to convert such
shares into shares of Common Stock pursuant to the terms set forth elsewhere
herein, (b) the Company shall not, directly or indirectly, declare or pay any
dividend or make any distribution on, or purchase, redeem or satisfy any
mandatory redemption, sinking fund or other similar obligation in respect of,
any securities ranking junior to the Parity Redemption Stock with respect to
liquidation preference or warrants, rights or 

                                     -10-

<PAGE>
 
options exercisable for any such junior securities, and (c) the Company shall
not, directly or indirectly, declare or pay any dividend or make any
distribution on, or purchase, redeem, or satisfy any mandatory redemption,
sinking fund or other similar obligation in respect of, any Parity Redemption
Stock, unless such dividends or distributions on each share of Parity Redemption
Stock are declared and paid on a pro rata basis, or, in the event any mandatory
redemption, sinking fund or other similar obligation is then undischarged with
respect to such Parity Redemption Stock, unless the shares of Parity Redemption
Stock are redeemed on a pro rata basis. For purposes of this Section 2.8.3.7,
"PRO RATA BASIS" shall refer to the proportion that the distribution payable to
holders of each series of Parity Redemption Stock, respectively, bears to the
aggregate distribution payable to all holders of Parity Redemption Stock. The
shares of Parity Redemption Stock required to be redeemed but not so redeemed
shall remain outstanding and entitled to all rights and preferences provided
herein. At any time thereafter when additional funds of the Company are legally
available for the redemption of such shares, such funds will be used, at the end
of the next succeeding fiscal quarter, to redeem the balance of such shares, or
such portion thereof for which funds are then legally available, on the basis
set forth above.

               2.8.3.8.  STATUS OF REDEEMED SHARES

          From and after each Redemption Date, unless default shall be made by
the Company in paying the Redemption Price at the time and place specified in
the Redemption Notice, no dividends on shares of Parity Redemption Stock to be
redeemed on such Redemption Date shall be declared or accrue and all rights of
holders of such shares shall cease, except the right of holders of such shares
to receive the applicable Redemption Price, against delivery of certificates
representing such shares and such shares shall cease to be outstanding.

          2.8.4.  CONVERSION RIGHTS

          The holders of Series A Stock and Series B Stock shall have the
following rights with respect to the conversion of such shares into shares of
Common Stock (the "CONVERSION RIGHTS"):

               2.8.4.1.  RIGHT TO CONVERT

                    2.8.4.1.1.  VOLUNTARY CONVERSION

          Each share of Series A Stock and Series B Stock may, at the option of
the holder, be converted at any time, including after the delivery of a
Liquidation Notice, into such number of fully paid and nonassessable shares of
Common Stock as is equal to the product obtained by multiplying the applicable

                                     -11-

<PAGE>
 
Series A Conversion Rate or Series B Conversion Rate (determined under Section
2.8.4.2) by the number of shares of Series A Stock or Series B Stock being
converted.

                    2.8.4.1.2.  MANDATORY CONVERSION

          Each outstanding share of Series A Stock and Series B Stock shall be
converted automatically, without any action by the holders of such shares and
whether or not the certificates representing such shares are surrendered to the
Company or its transfer agent, into the number of shares of Common Stock into
which such Series A Stock or Series B Stock is convertible pursuant to Section
2.8.4.1.1 upon the earliest of (a) the moment immediately prior to the closing
of a firmly underwritten, public offering of shares of Common Stock, registered
under the Securities Act of 1933, as amended, in which the aggregate gross
offering proceeds (before deduction of underwriters' discounts and commissions
and expenses of the offering) are in excess of $20,000,000 and (i) with respect
to the automatic conversion of shares of Series A Stock, the per share price at
which such shares of Common Stock are offered to the public is at least equal to
$4.14 (adjusted to reflect the occurrence of any Extraordinary Common Stock
Event (as defined below)), (ii) with respect to the automatic conversion of
shares of Series B Stock, (A) if the closing of such offering is on or before
September 30, 1998, the per share price at which such shares of Common Stock are
offered to the public is at least equal to $12.70 (adjusted to reflect the
occurrence of any Extraordinary Common Stock Event), or (B) thereafter, the per
share price at which such shares of Common Stock are offered to the public is at
least equal to $19.05 (adjusted to reflect the occurrence of any Extraordinary
Common Stock Event) or (b) the effectiveness of any consent to or vote in favor
of such conversion by holders of a majority of the then outstanding shares of
such series.

               2.8.4.2.  CONVERSION RATES

          The conversion rate for Series A Stock in effect at any time (the
"SERIES A CONVERSION RATE") shall equal $1.38 divided by the Series A Conversion
Price, calculated as provided in Section 2.8.4.3.  The conversion rate for
Series B Stock in effect at any time (the "SERIES B CONVERSION RATE") shall
equal $6.35 divided by the Series B Conversion Price, calculated as provided in
Section 2.8.4.3.

               2.8.4.3.  CONVERSION PRICES

          The conversion price for Series A Stock in effect from time to time
shall initially be $1.38, subject to adjustment, in accordance with Section
2.8.4.4 (the "SERIES A CONVERSION PRICE").  The conversion price for Series B
Stock in effect from 

                                     -12-

<PAGE>
 
time to time shall initially be $6.35, subject to adjustment, in accordance with
Section 2.8.4.4 (the "SERIES B CONVERSION PRICE").

               2.8.4.4.  ADJUSTMENTS TO APPLICABLE CONVERSION PRICE

                    2.8.4.4.1.  EXTRAORDINARY COMMON STOCK EVENT

          Upon the happening of an Extraordinary Common Stock Event (as defined
below) after the date of the initial issuance of any shares of Series A Stock or
Series B Stock, the Series A Conversion Price and Series B Conversion Price, as
applicable, shall, simultaneously with the happening of such Extraordinary
Common Stock Event, be adjusted by multiplying the then effective Series A
Conversion Price or Series B Conversion Price, as applicable, by a fraction, the
numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to such Extraordinary Common Stock Event and the denominator
of which shall be the number of shares of Common Stock outstanding immediately
after such Extraordinary Common Stock Event, and the product so obtained shall
thereafter be the Series A Conversion Price and Series B Conversion Price,
respectively.  The Series A Conversion Price and Series B Conversion Price, as
so adjusted, shall be readjusted in the same manner upon the happening of any
successive Extraordinary Common Stock Event or Events.  "EXTRAORDINARY COMMON
STOCK EVENT" shall mean (a) the issuance of additional shares of Common Stock as
a dividend or other distribution on outstanding Common Stock of the Company, (b)
a subdivision of outstanding shares of Common Stock into a greater number of
shares of Common Stock, or (c) a combination of outstanding shares of Common
Stock into a smaller number of shares of Common Stock.

                    2.8.4.4.2.  SALE OF SHARES BELOW APPLICABLE CONVERSION PRICE

          (a) If, at any time after March 31, 1997, the Company shall issue any
Additional Stock (as defined in Section 2.8.4.5) without consideration or for a
consideration per share less than the Series A Conversion Price or Series B
Conversion Price, as applicable, in effect immediately before the issuance of
such Additional Stock, the respective Series A Conversion Price and Series B
Conversion Price in effect upon issuance (except as otherwise provided in this
Section 2.8.4.4.2) shall be adjusted to a price equal to the quotient obtained
by dividing the total computed under clause (x) below by the total computed
under clause (y) below as follows:

                                     -13-

<PAGE>
 
          (x) an amount equal to the sum of (i) the result obtained by
multiplying the number of shares of Common Stock deemed outstanding immediately
prior to such issuance (which shall include the actual number of shares
outstanding plus all shares issuable upon the conversion or exercise of all
outstanding convertible securities, warrants and options) by the Series A
Conversion Price or Series B Conversion Price, as applicable, then in effect,
and (ii) the aggregate consideration, if any, received by the Company upon the
issuance of such Additional Stock;

          (y) the number of shares of Common Stock of the Company outstanding
immediately after each issuance (including the shares deemed outstanding as
provided above).

          (b) No adjustment of the Series A Conversion Price or Series B
Conversion Price shall be made in an amount less than $.01 per share; provided
that any adjustments that are not required to be made by reason of this sentence
shall be carried forward and shall be taken into account in any subsequent
adjustment made to the respective Series A Conversion Price or Series B
Conversion Price.  Except as provided in Subsections 2.8.4.4.1 and
2.8.4.4.2(e)(iii) and (iv), no adjustment of the Series A Conversion Price or
Series B Conversion Price pursuant to this Section 2.8.4.4.2 shall have the
effect of increasing the respective Series A Conversion Price or Series B
Conversion Price above the respective Series A Conversion Price or Series B
Conversion Price in effect immediately before such adjustment.

          (c) In the case of the issuance of Common Stock for cash, the
consideration shall be deemed to be the amount of cash paid therefor before
deducting any discounts, commissions or other expenses allowed, paid or incurred
by the Company for any underwriting or otherwise in connection with the issuance
and sale thereof.

          (d) In the case of the issuance of Common Stock for consideration in
whole or in part other than cash, the consideration other than cash shall be
deemed to be the fair value thereof as determined by the Board irrespective of
any accounting treatment.

          (e) In the case of the issuance of options to purchase or rights to
subscribe for Common Stock, securities by their terms convertible into or
exchangeable for Common Stock, or options to purchase or rights to subscribe for
such convertible or exchangeable securities (which options, rights, or
convertible or exchangeable securities are not excluded from the definition of
Additional Stock), the following provisions shall apply:

                                     -14-

<PAGE>
 
          (i) the aggregate maximum number of shares of Common Stock deliverable
upon exercise of such options to purchase or rights to subscribe for Common
Stock shall be deemed to have been issued at the time such options or rights
were issued for a consideration equal to the consideration (determined in the
manner provided in Subsections 2.8.4.4.2(c) and (d)) received by the Company
upon the issuance of such options or rights, plus the minimum purchase price
provided in such options or rights for the Common Stock covered thereby, but no
further adjustment to the Series A Conversion Price or Series B Conversion Price
shall be made for the actual issuance of Common Stock upon the exercise of such
options or rights in accordance with their terms;

          (ii) the aggregate maximum number of shares of Common Stock
deliverable upon conversion of or in exchange for any such convertible or
exchangeable securities or upon the exercise of options to purchase or rights to
subscribe for such convertible or exchangeable securities and subsequent
conversion or exchange thereof shall be deemed to have been issued at the time
such securities were issued or such options or rights were issued for a
consideration equal to the consideration received by the Company for any such
securities and related options or rights, plus the additional consideration, if
any, to be received by the Company upon the conversion or exchange of such
securities or the exercise of any related options or rights (the consideration
in each case to be determined in the manner provided in Subsections 2.8.4.4.2(c)
and (d)), but no further adjustments to the Series A Conversion Price or Series
B Conversion Price shall be made for the actual issuance of Common Stock upon
the conversion or exchange of such securities in accordance with their terms;

          (iii)  if such options, rights, or convertible or exchangeable
securities by their terms provide, with the passage of time or otherwise, for
any increase in the consideration payable to the Company, or decrease in the
number of shares of Common Stock issuable, upon the exercise, conversion or
exchange thereof, the respective Series A Conversion Price or Series B
Conversion Price computed upon the original issue thereof, and any subsequent
adjustments based thereon, shall, upon such increase or decrease becoming
effective, be recomputed to reflect such increase or decrease with respect to
such options, rights and securities not already exercised, converted or
exchanged before such increase or decrease became effective, but no further
adjustment to the Series A Conversion Price or Series B Conversion Price shall
be made for the actual issuance of Common Stock upon the exercise of any such
options or rights or the conversion or exchange of such securities in accordance
with their terms;

                                     -15-

<PAGE>
 
          (iv) upon the expiration of any such options or rights, the
termination of any such rights to convert or exchange, or the expiration of any
options or rights related to such convertible or exchangeable securities, the
Series A Conversion Price and Series B Conversion Price, as applicable, shall
forthwith be readjusted to such Series A Conversion Price and Series B
Conversion Price as would have been obtained had the adjustment that was made
upon the issuance of such options, rights, or securities or options or rights
related to such securities been made upon the basis of the issuance of only the
number of shares of Common Stock actually issued upon the exercise of such
options or rights, upon the conversion or exchange of such securities or upon
the exercise of the options or rights related to such securities; and

          (v) if any such options or rights shall be issued in connection with
the issuance and sale of other securities of the Company, together comprising
one integral transaction in which no specific consideration is allocated to such
options or rights by the parties thereto, such options or rights shall be deemed
to have been issued for such consideration as determined in good faith by the
Board.

               2.8.4.5.  ADDITIONAL STOCK

          "Additional Stock" shall mean any shares of Common Stock or securities

the Series B Stock, voting as two separate classes.

               2.8.4.6.  MECHANICS OF CONVERSION

          Conversion shall be deemed to have been effected immediately prior to
the close of business on the Conversion Date (as defined below for voluntary
conversions and for mandatory conversions), and at such time, whether or not
certificates representing the shares being converted shall have been received by
the Company or its transfer agent in the case of a mandatory conversion, the
rights of the holder as holder of the converted shares of Series A Stock or

therefor, duly endorsed, at the office of the Company or of any transfer agent

prepaid, addressed to the same location at which the certificate or certificates
were or will be surrendered, of the election to convert such shares and shall

pursuant to Section 2.8.4.1.1, the date when written notice of the holder's
election to convert is received by the Company or a transfer agent for the
shares to be converted, together with the certificate or certificates
representing the shares to be converted, shall be the "CONVERSION DATE."

                    2.8.4.6.2.  MANDATORY CONVERSION

          In the event some but not all of the shares of Series A Stock or

          If any capital reorganization or reclassification of the capital stock
of the Company shall be effected in such a way that holders of Common Stock
shall be entitled to receive stock, securities or assets with respect to or in
exchange for Common Stock, then, as a condition of such reorganization or
reclassification, lawful and adequate provisions shall be made whereby each
holder of a share or shares of 

                                     -18-

<PAGE>
 
Series A Stock and Series B Stock shall thereupon have the right to receive,

shares of stock, securities or assets as may be issued or payable with respect
to or in exchange for a number of outstanding shares of such Common Stock equal
to the number of shares of such Common Stock immediately theretofore receivable
upon such conversion had such reorganization or reclassification not taken
place, and in any such case appropriate provisions shall be made with respect to
the rights and interests of such holder to the end that the provisions hereof
(including without limitation provisions for adjustments of the applicable
Conversion Price) shall thereafter be applicable, as nearly as may be, in
relation to any shares of stock, securities or assets thereafter deliverable
upon the exercise of the Conversion Rights.

               2.8.4.8.  OTHER NOTICES

          The Company shall at all times reserve and keep available out of its
authorized but unissued shares of Common Stock, solely for the purpose of

benefit in money, property or services to which the director is not legally

to authorize corporate action further eliminating or limiting the personal
liability of directors, then the liability of a director of the Company shall be
eliminated or limited to the full extent permitted by the Washington Business
Corporation Act, as so amended, without any requirement of further action by the
shareholders.

6.  INDEMNIFICATION

     The Company shall indemnify any individual made a party to a proceeding

may be disregarded if authorized by the Articles of Incorporation, to the full

     Any repeal or modification of this Article by the shareholders of the
Company shall not adversely affect any right of any individual who is or was a
director of the Company which existed at the time of such repeal or
modification.

          5.  DIRECTORS

          5.1.  NUMBER; ELECTION; TERM

               Following a Full Conversion Event, the number of Directors of the
          Company shall be determined, and the Directors of the Company shall be
          elected and removed from office, as provided in this Section 5.1.

               The number of Directors of the Company shall be determined in the
          manner provided by the Bylaws and may be increased or decreased from
          time to time in the manner provided therein.  Prior to the first
          annual election of Directors following such a Full Conversion Event,
          unless a Director earlier dies, resigns or is removed, his or her term
          of office shall expire at the next annual meeting of shareholders.  At
          the first annual election of Directors following such a Full
          Conversion Event, the Board shall be divided into three classes, with
          said classes to be as equal in number as may be possible, with any
          Director or Directors in excess of the number divisible by three being
          assigned to Class 3 and Class 2, as the case may be.  At the first
          election of Directors to such classified Board, each Class 1 Director
          shall be elected to serve until the next ensuing annual meeting of
          shareholders, each Class 2 Director shall be elected to serve until
          the second ensuing annual meeting of shareholders and each Class 3
          Director shall be elected to serve until the third ensuing annual
          meeting of shareholders.  At each annual meeting of shareholders
          following the meeting at which the Board is initially classified, the
          number of Directors equal to the number of Directors in the class
          whose term expires at the time of such meeting shall be elected to
          serve until the third ensuing annual meeting of shareholders.
          Notwithstanding any of the foregoing provisions of this Article,
          Directors shall serve until their successors are elected and qualified
          or until their earlier death, resignation or removal from office, or
          until there is a decrease in the number of Directors.

               The Directors of the Company may be removed only for cause; such
          removal shall be in the manner provided by the Bylaws.

          5.2.  LIMITATION OF DIRECTOR LIABILITY

               A director of the Company shall not be personally liable to the
          Company or its shareholders for monetary damages for conduct as a
          director, except for liability of the director (i) for acts or
          omissions that involve intentional misconduct by the director or a
          knowing violation of law by the director, (ii) for conduct violating
          RCW 23B.08.310 of the Washington Business Corporation Act, or (iii)
          for any transaction from which the director will personally receive a
          benefit in money, property or services to which the director is not
          legally entitled.  If the Washington Business Corporation Act is
          amended in the future to authorize corporate action further
          eliminating or limiting the personal liability of directors, then the
          liability of a director of the Company shall be eliminated or limited
          to the full extent permitted by the Washington Business Corporation
          Act, as so amended, without any requirement of further action by the
          shareholders.

     8.  A new Section 7 has been added to read as follows:

                           ONYX SOFTWARE CORPORATION


                              SECTION 1. OFFICES

     The principal office of the corporation shall be located at the principal
place of business or such other place as the Board of Directors ("BOARD") may
designate.  The corporation may have such other offices as the Board may
designate or as the business of the corporation may require.

                            SECTION 2. SHAREHOLDERS

2.1  ANNUAL MEETING

     The annual meeting of the shareholders shall be held on the second Tuesday
in the month of March in each year at 9:00 a.m., or at such other date or time
as may be determined by the Board of Directors for the purpose of electing
Directors and transacting such other business as may properly come before the
meeting.  If the day fixed for the annual meeting is a legal holiday at the
place of the meeting, the meeting shall be held on the next succeeding business
day.

2.2  SPECIAL MEETINGS

     The Chairman of the Board, the President or the Board may call special
meetings of the shareholders for any purpose.  Further, a special meeting of the
shareholders shall be held if the holders of not less than 25% of all the votes
entitled to be cast on any issue proposed to be considered at such special
meeting have dated, signed and delivered to the Secretary one or more written
demands for such meeting, describing the purpose or purposes for which it is to
be held.

2.3  MEETINGS BY COMMUNICATIONS EQUIPMENT

     Shareholders may participate in any meeting of the shareholders by any
means of communication by which all persons participating in the meeting can
hear each other during the meeting.  Participation by such means shall

<PAGE>
 
2.4  DATE, TIME AND PLACE OF MEETING

     Except as otherwise provided in these Bylaws, all meetings of shareholders,
including those held pursuant to demand by shareholders, shall be held on such
date and at such time and place designated by or at the direction of the Board.

2.5  NOTICE OF MEETING

     Written notice stating the place, day and hour of the meeting and, in the
case of a special meeting, the purpose or purposes for which the meeting is
called shall be given by or at the direction of the Board, the Chairman of the
Board, the President or the Secretary to each shareholder entitled to notice of
or to vote at the meeting not less than 10 nor more than 60 days before the
meeting, except that notice of a meeting to act on an amendment to the Articles
of Incorporation, a plan of merger or share exchange, the sale, lease, exchange
or other disposition of all or substantially all of the corporation's assets
other than in the regular course of business or the dissolution of the
corporation shall be given not less than 20 or more than 60 days before such
meeting.  If an annual or special shareholders' meeting is adjourned to a
different date, time or place, no notice of the new date, time or place is
required if they are announced at the meeting before adjournment.  If a new
record date for the adjourned meeting is or must be fixed, notice of the
adjourned meeting must be given to shareholders entitled to notice of or to vote
as of the new record date.

     Such notice may be transmitted by mail, private carrier, personal delivery,
telegraph, teletype or communications equipment that transmits a facsimile of
the notice.  If these forms of written notice are impractical in the view of the
Board, the Chairman of the Board, the President or the Secretary, written notice
may be transmitted by an advertisement in a newspaper of general circulation in
the area of the corporation's principal office.  If such notice is mailed, it is
effective when deposited in the official government mail, first-class postage
prepaid, properly addressed to the shareholder at such shareholder's address as
it appears in the corporation's current record of shareholders.  Notice given in
any other manner is  effective when dispatched to the shareholder's address,
telephone number or other number appearing on the records of the corporation.
Any notice given by publication is  effective five days after first publication.

2.6  BUSINESS FOR SHAREHOLDERS' MEETINGS

     2.6.1 BUSINESS AT ANNUAL MEETINGS

     In addition to the election of directors, other proper business may be
transacted at an annual meeting of shareholders, provided that such business is
properly brought before such meeting.  To be properly brought before an annual
meeting, business must be (a) brought by or at the direction of the Board or (b)
brought before the meeting by a shareholder pursuant to written notice thereof,
in accordance with subsection 2.6.3 hereof, and received by the Secretary not
fewer than 90 nor more than 120 days prior to the anniversary date of the prior

                                      -2-
<PAGE>
 
year's annual meeting.  Any such shareholder notice shall set forth (i) the name
and address of the shareholder proposing such business; (ii) a representation
that the shareholder is entitled to vote at such meeting and a statement of the
number of shares of the corporation which are beneficially owned by the
shareholder; (iii) a representation that the shareholder intends to appear in
person or by proxy at the meeting to propose such business; and (iv) as to each
matter the Articles of Amendment proposes to bring before the meeting, a brief
description of the business desired to be brought before the meeting, the
reasons for conducting such business at the meeting, the language of the
proposal (if appropriate), and any material interest of the shareholder in such
business.  No business shall be conducted at any annual meeting of shareholders
except in accordance with this subsection 2.6.1.  If the facts warrant, the
Board, or the chairman of an annual meeting of shareholders, may determine and
declare that (a) that a proposal does not constitute proper business to be
transacted at the meeting or (b) that business was not properly brought before
the meeting in accordance with the provisions of this subsection 2.6.1 and, if,
in either case, it is so determined, any such business shall not be transacted.
In addition to the procedures set forth in this subsection 2.6.1, shareholders
desiring to include a proposal in the Company's proxy statement must also comply
with the requirements set forth in Rule 14a-8 under Section 14 of the Securities
Exchange Act of 1934, as amended, or any successor provision.

     2.6.2 BUSINESS AT SPECIAL MEETINGS

     At any special meeting of the shareholders, only such business as is
specified in the notice of such special meeting given by or at the direction of
the person or persons calling such meeting, in accordance with subsection 2.4
hereof, shall come before such meeting.

     2.6.3 NOTICE TO CORPORATION

     Any written notice required to be delivered by a shareholder to the
corporation pursuant to subsection 2.2, subsection 2.4, subsection 2.6.1 or
subsection 2.6.2 hereof must be given, either by personal delivery or by
registered or certified mail, postage prepaid, to the Secretary at the
corporation's principal executive offices in the City of Bellevue, State of
Washington.

2.7  WAIVER OF NOTICE

     Whenever any notice is required to be given to any shareholder under the
provisions of these Bylaws, the Articles of Incorporation or the Washington
Business Corporation Act, a waiver of notice in writing, signed by the person or
persons entitled to such notice and delivered to the corporation, whether before
or after the date and time of the meeting or before or after the action to be
taken by consent is effective, shall be the equivalent of the giving of such
notice.  Further, notice of the time, place and purpose of any meeting will be
waived by any shareholder by attendance in person or by proxy, unless such
shareholder at the beginning of the meeting objects to holding the meeting or
transacting business at the meeting.

                                      -3-
<PAGE>
 
2.8  FIXING OF RECORD DATE FOR DETERMINING SHAREHOLDERS

     For the purpose of determining shareholders entitled (a) to notice of or to
vote at any meeting of shareholders or any adjournment thereof, (b) to demand a
special meeting, or (c) to receive payment of any dividend, or in order to make
a determination of shareholders for any other purpose, the Board may fix a
future date as the record date for any such determination.  Such record date
shall be not more than 70 days, and, in case of a meeting of shareholders, not
less than 10 days, prior to the date on which the particular action requiring
such determination is to be taken.  If no record date is fixed for the
determination of shareholders entitled to notice of or to vote at a meeting, the
record date shall be the day immediately preceding the date on which notice of
the meeting is first given to shareholders.  Such a determination shall apply to
any adjournment of the meeting unless the Board fixes a new record date, which
it shall do if the meeting is adjourned to a date more than 120 days after the
date fixed for the original meeting.  If no record date is set for the
determination of shareholders entitled to receive payment of any stock dividend
or distribution (other than one involving a purchase, redemption, or other
acquisition of the corporation's shares) the record date shall be the date the
Board authorizes the stock dividend or distribution.

2.9  VOTING RECORD

     At least 10 days before each meeting of shareholders, an alphabetical list
of the shareholders entitled to notice of such meeting shall be made, arranged
by voting group and by each class or series of shares, with the address of and
number of shares held by each shareholder.  This record shall be kept at the
principal office of the corporation for 10 days prior to such meeting, and shall
be kept open at such meeting, for the inspection of any shareholder or any
shareholder's agent or attorney.

2.10 QUORUM

     A majority of the votes entitled to be cast on a matter by the holders of
shares that, pursuant to the Articles of Incorporation or the Washington
Business Corporation Act, are entitled to vote and be counted collectively upon
such matter, represented in person or by proxy, shall constitute a quorum of
such shares at a meeting of shareholders.  If less than a majority of such votes
are represented at a meeting, a majority of the votes so represented may adjourn
the meeting from time to time.  Any business may be transacted at a reconvened
meeting that might have been transacted at the meeting as originally called,
provided a quorum is present or represented at such meeting.  Once a share is
represented for any purpose at a meeting other than solely to object to holding
the meeting or transacting business, it is deemed present for quorum purposes
for the remainder of the meeting and any adjournment (unless a new record date
is or must be set for the adjourned meeting) notwithstanding the withdrawal of
enough shareholders to leave less than a quorum.

                                      -4-
<PAGE>
 
2.11 MANNER OF ACTING

     If a quorum is present, action on a matter other than the election of
Directors shall be approved if the votes cast in favor of the action by the
shares entitled to vote and be counted collectively upon such matter exceed the
votes cast against such action by the shares entitled to vote and be counted
collectively thereon, unless the Articles of Incorporation or the Washington
Business Corporation Act requires a greater number of affirmative votes.

2.12 PROXIES

     A shareholder may vote by proxy executed in writing by the shareholder or
by his or her attorney-in-fact or agent.  Such proxy shall be effective when
received by the Secretary or other officer or agent authorized to tabulate
votes.  A proxy shall become invalid 11 months after the date of its execution,
unless otherwise provided in the proxy.  A proxy with respect to a specified
meeting shall entitle its holder to vote at any reconvened meeting following
adjournment of such meeting but shall not be valid after the final adjournment.

2.13 VOTING OF SHARES

     Except as provided in the Articles of Incorporation or in Section 2.14,
each outstanding share entitled to vote with respect to a matter submitted to a
meeting of shareholders shall be entitled to one vote upon such matter.

2.14 VOTING FOR DIRECTORS

     Each shareholder entitled to vote at an election of Directors may vote, in
person or by proxy, the number of shares owned by such shareholder for as many
persons as there are Directors to be elected and for whose election such
shareholder has a right to vote, or (unless otherwise provided in the Articles
of Incorporation), each such shareholder may cumulate such shareholder's votes
by distributing among one or more candidates as many votes as are equal to the
number of such Directors multiplied by the number of such shareholder's shares.
Unless otherwise provided in the Articles of Incorporation, the candidates
elected shall be those receiving the largest number of votes cast, up to the
number of Directors to be elected.

2.15 ACTION BY SHAREHOLDERS WITHOUT A MEETING

     Any action that may or is required to be taken at a meeting of the
shareholders may be taken without a meeting by unanimous consent if one or more
written consents setting forth the action so taken shall be signed by all the
shareholders entitled to vote with respect to the matter.  Unless the consent
specifies a later effective date, actions taken by written consent of the
shareholders are effective when (a) consents sufficient to authorize taking the
action are in possession of the corporation and (b) the period of advance notice
required by the Articles of Incorporation to be given to any nonconsenting or
nonvoting shareholders has been 

                                      -5-
<PAGE>
 
satisfied. Any such consent shall be inserted in the minute book as if it were
the minutes of a meeting of the shareholders.

                         SECTION 3. BOARD OF DIRECTORS

3.1  GENERAL POWERS

     All corporate powers shall be exercised by or under the authority of, and

3.2  NUMBER AND TENURE

     The Board shall be composed of not less than 1 nor more than 11 Directors,
the specific number to be set by resolution of the Board.  The number of
Directors may be changed from time to time by amendment to these Bylaws, but no
decrease in the number of Directors shall have the effect of shortening the term
of any incumbent Director.  Unless a Director dies, resigns, or is removed, his
or her term of office shall expire at the next annual meeting of shareholders;
provided, however, that a Director shall continue to serve until his or her
successor is elected or until there is a decrease in the authorized number of
Directors.  Directors need not be shareholders of the corporation or residents
of the state of Washington and need not meet any other qualifications.

3.3  ANNUAL AND REGULAR MEETINGS

     An annual Board meeting shall be held without notice immediately after and
at the same place as the annual meeting of shareholders.  By resolution the
Board, or any committee designated by the Board, may specify the time and place
for holding regular meetings without notice other than such resolution.

3.4  SPECIAL MEETINGS

     Special meetings of the Board or any committee designated by the Board may
be called by or at the request of the Chairman of the Board, the President, the
Secretary or, in the case of special Board meetings, any Director and, in the
case of any special meeting of any committee designated by the Board, by its
Chairman.  The person or persons authorized to call special meetings may fix any
place for holding any special Board or committee meeting called by them.

3.5  MEETINGS BY COMMUNICATIONS EQUIPMENT

     Members of the Board or any committee designated by the Board may
participate in a meeting of such Board or committee by, or conduct the meeting
through the use of, any means of communication by which all Directors
participating in the meeting can hear each 

                                      -6-
<PAGE>
 
other during the meeting. Participation by such means shall constitute presence
in person at a meeting.

3.6  NOTICE OF SPECIAL MEETINGS

     Notice of a special Board or committee meeting stating the place, day and
hour of the meeting shall be given to a Director in writing or orally, as
provided below.  Neither the business to be transacted at nor the purpose of any
special meeting need be specified in the notice of such meeting.

     3.6.1 PERSONAL DELIVERY

     If notice is given by personal delivery, the notice shall be delivered to a
Director at least two days before the meeting.

     3.6.2 DELIVERY BY MAIL

     If notice is given by private carrier, the notice shall be dispatched to a
Director at his or her address shown on the records of the corporation at least
three days before the meeting.

     3.6.4 FACSIMILE NOTICE

     If notice is delivered by wire or wireless equipment that transmits a
facsimile of the notice, the notice shall be dispatched at least two days before
the meeting to a Director at his or her telephone number or other number
appearing on the records of the corporation.

     3.6.5 DELIVERY BY TELEGRAPH

wireless equipment that does not transmit a facsimile of the notice, the notice
shall be communicated to the Director at least two days before the meeting.

                                      -7-
<PAGE>
 
3.7  WAIVER OF NOTICE

     3.7.1 IN WRITING

     Whenever any notice is required to be given to any Director under the
provisions of these Bylaws, the Articles of Incorporation or the Washington
Business Corporation Act, a waiver thereof in writing, signed by the person or
persons entitled to such notice and delivered to the corporation, whether before
or after the date and time of the meeting, shall be deemed equivalent to the
giving of such notice.  Neither the business to be transacted at nor the purpose
of any regular or special meeting of the Board or any committee designated by
the Board need be specified in the waiver of notice of such meeting.

     3.7.2 BY ATTENDANCE

     A Director's attendance at or participation in a Board or committee meeting
shall constitute a waiver of notice of such meeting, unless the Director at the
beginning of the meeting, or promptly upon his or her arrival, objects to
holding the meeting or transacting business at such meeting and does not
thereafter vote for or assent to action taken at the meeting.

3.8  QUORUM

     A majority of the number of Directors fixed by or in the manner provided in
these Bylaws shall constitute a quorum for the transaction of business at any
Board meeting but, if less than a majority are present at a meeting, a majority
of the Directors present may adjourn the meeting from time to time without
further notice.  A majority of the number of Directors composing any committee
of the Board, as established and fixed by resolution of the Board, shall
constitute a quorum for the transaction of business at any meeting of such
committee but, if less than a majority are present at a meeting, a majority of
such Directors present may adjourn the committee meeting from time to time
without further notice.

3.9  MANNER OF ACTING

     If a quorum is present when the vote is taken, the act of the majority of
the Directors present at a Board or committee meeting shall be the act of the
Board or such committee, unless the vote of a greater number is required by
these Bylaws, the Articles of Incorporation or the Washington Business
Corporation Act.

3.10 PRESUMPTION OF ASSENT

     A Director of the corporation who is present at a Board or committee
meeting at which any action is taken shall be deemed to have assented to the
action taken unless (a) the Director objects at the beginning of the meeting, or
promptly upon the Director's arrival, to holding the meeting or transacting any
business at such meeting, (b) the Director's dissent or abstention from the
action taken is entered in the minutes of the meeting, or (c) the Director

                                      -8-
<PAGE>
 
delivers written notice of the Director's dissent or abstention to the presiding
officer of the meeting before its adjournment or to the corporation within a
reasonable time after adjournment of the meeting.  The right of dissent or
abstention is not available to a Director who votes in favor of the action
taken.

3.11 ACTION BY BOARD OR COMMITTEES WITHOUT A MEETING

     Any action that could be taken at a meeting of the Board or of any
committee created by the Board may be taken without a meeting if one or more
written consents setting forth the action so taken are signed by each of the
Directors or by each committee member either before or after the action is taken
and delivered to the corporation.  Action taken by written consent of Directors
without a meeting is effective when the last Director signs the consent, unless
the consent specifies a later effective date.  Any such written consent shall be
inserted in the minute book as if it were the minutes of a Board or a committee
meeting.

3.12 RESIGNATION

     Any Director may resign from the Board or any committee of the Board at any
time by delivering either oral tender of resignation at any meeting of the Board
or any committee or written notice to the Chairman of the Board, the President,
the Secretary or the Board.  Any such resignation is effective upon delivery
thereof unless the notice of resignation specifies a later effective date and,
unless otherwise specified therein, the acceptance of such resignation shall not
be necessary to make it effective.

3.13 REMOVAL

     At a meeting of shareholders called expressly for that purpose, one or more
members of the Board, including the entire Board, may be removed with or without
cause (unless the Articles of Incorporation permit removal for cause only) by
the holders of the shares entitled to elect the Director or Directors whose
removal is sought if the number of votes cast to remove the Director exceeds the
number of votes cast not to remove the Director.

3.14 VACANCIES

     Unless the Articles of Incorporation provide otherwise, any vacancy
occurring on the Board may be filled by the shareholders, the Board or, if the
Directors in office constitute fewer than a quorum, by the affirmative vote of a
majority of the remaining Directors.  Any vacant office to be held by a Director
elected by the holders of one or more classes or series of shares entitled to
vote and be counted collectively thereon shall be filled only by the vote of the
holders of such class or series of shares.  A Director elected to fill a vacancy
shall serve only until the next election of Directors by the shareholders.

executive officer of the corporation to do so within limits specifically
prescribed by the Board.

     3.15.3 MINUTES OF MEETINGS

     All committees shall keep regular minutes of their meetings and shall cause
them to be recorded in books kept for that purpose.

     3.15.4 REMOVAL

     The Board may remove any member of any committee elected or appointed by it
but only by the affirmative vote of the greater of a majority of the Directors

                          SECTION 10. INDEMNIFICATION

     Each person who was, is or is threatened to be made a party to or is
otherwise involved (including, without limitation, as a witness) in any
threatened, pending or completed action, suit, claim or proceeding, whether
civil, criminal, administrative or investigative and whether formal or informal
(hereafter a "PROCEEDING"), by reason of the fact that he or she is or was a
Director or officer of the corporation or, that being or having been such a
Director or officer or an employee of the corporation, he or she is or was
serving at the request of the corporation as a Director, officer, partner,
trustee, employee or agent of another corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise (hereafter an "INDEMNITEE"),
whether the basis of a proceeding is alleged action in an official capacity or
in any other capacity while serving as such a Director, officer, partner,
trustee, employee or agent shall be indemnified and held harmless by the
corporation against all losses, claims, damages (compensatory, exemplary,
punitive or otherwise), liabilities and expenses (including attorneys' fees,
costs, judgments, fines, ERISA excise taxes or penalties, amounts to be paid in
settlement and any other expenses) actually and reasonably incurred or suffered
by such indemnitee in connection therewith and such indemnification shall
continue as to an indemnitee who has ceased to be a Director or officer of the
Company or a Director, officer partner, trustee, employee or agent of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise and shall inure to the benefit of the indemnitee's 

                                     -16-
<PAGE>
 
heirs, executors and administrators. Except as provided in subsection 10.4 of
this Section with respect to proceedings seeking to enforce rights to
indemnification, the corporation shall indemnify any such indemnitee in
connection with a proceeding (or part thereof) initiated by such indemnitee only
if a proceeding (or part thereof) was authorized or ratified by the Board. The
right to indemnification conferred in this Section shall be a contract right.

10.2 RESTRICTIONS ON INDEMNIFICATION

     No indemnification shall be provided to any such indemnitee for acts or
omissions of the indemnitee finally adjudged to be intentional misconduct or a
knowing violation of law, for conduct of the indemnitee finally adjudged to be
in violation of Section 23B.08.310 of the Washington Business Corporation Act,
for any transaction with respect to which it was finally adjudged that such
indemnitee personally received a benefit in money, property or services to which
the indemnitee was not legally entitled or if the corporation is otherwise
prohibited by applicable law from paying such indemnification.  Notwithstanding
the foregoing, if Section 23B.08.560 or any successor provision of the
Washington Business Corporation Act is hereafter amended, the restrictions on
indemnification set forth in this subsection 10.2 shall be as set forth in such
amended statutory provision.

10.3 ADVANCEMENT OF EXPENSES

     The right to indemnification conferred in this Section shall include the
right to be paid by the corporation the expenses incurred in defending any
proceeding in advance of its final disposition (hereinafter an "advancement of
expenses").  An advancement of expenses shall be made upon delivery to the
corporation of an undertaking (hereinafter an "undertaking"), by or on behalf of
such indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal that such indemnitee is not entitled to be indemnified.

10.4 RIGHT OF INDEMNITEE TO BRING SUIT

     If a claim under subsection 10.1 or 10.3 of this Section is not paid in
full by the corporation within 60 days after a written claim has been received
by the corporation, except in the case of a claim for an advancement of
expenses, in which case the applicable period shall be 20 days, the indemnitee
may at any time thereafter bring suit against the corporation to recover the
unpaid amount of the claim.  If successful in whole or in part, in any such suit
or in a suit brought by the corporation to recover an advancement of expenses
pursuant to the terms of an undertaking, the indemnitee shall be entitled to be
paid also the expense of litigating such suit.  The indemnitee shall be presumed
to be entitled to indemnification under this Section upon submission of a
written claim (and, in an action brought to enforce a claim for an advancement
of expenses, when the required undertaking has been tendered to the corporation)
and thereafter the corporation shall have the burden of proof to overcome the
presumption that the indemnitee is so entitled.

advancement of expenses set forth in this Section are in lieu of the procedures
required by Section 23B.08.550 or any successor provision of the Washington
Business Corporation Act.

10.6 NONEXCLUSIVITY OF RIGHTS

     Except as set forth in subsection 10.5, the right to indemnification and
the advancement of expenses conferred in this Section shall not be exclusive of
any other right that any person may have or hereafter acquire under any statute,
provision of the Articles of Incorporation or Bylaws of the corporation, general
or specific action of the Board or shareholders, contract or otherwise.

10.7 INSURANCE, CONTRACTS AND FUNDING

     The corporation may maintain insurance, at its expense, to protect itself
and any Director, officer, partner, trustee, employee or agent of the
corporation or another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise against any expense, liability or loss, whether
or not the corporation would have the authority or right to indemnify such
person against such expense, liability or loss under the Washington Business
Corporation Act or other law.  The corporation may enter into contracts with any
Director, officer, partner, trustee, employee or agent of the corporation in
furtherance of the provisions of this Section and may create a trust fund, grant
a security interest or use other means (including, without limitation, a letter
of credit) to ensure the payment of such amounts as may be necessary to effect
indemnification as provided in this Section.

10.8 INDEMNIFICATION OF EMPLOYEES AND AGENTS OF THE CORPORATION

     In addition to the rights of indemnification set forth in subsection 10.1,
the corporation may, by action of the Board, grant rights to indemnification and
advancement of expenses to employees and agents or any class or group of
employees and agents of the corporation (a) with the same scope and effect as
the provisions of this Section with respect to indemnification and the
advancement of expenses of Directors and officers of the corporation; (b)
pursuant to rights granted or provided by the Washington Business Corporation
Act; or (c) as are otherwise consistent with law.

10.9 PERSONS SERVING OTHER ENTITIES

     Any person who, while a Director, officer or employee of the corporation,
is or was serving (a) as a Director, officer, employee or agent of another
corporation of which a majority of the shares entitled to vote in the election
of its directors is held by the corporation or (b) as a partner, trustee or
otherwise in an executive or management capacity in a partnership, joint

subsidiary of the corporation is a general partner or has a majority ownership
shall conclusively be deemed to be so serving at the request of the corporation
and entitled to indemnification and the advancement of expenses under
subsections 10.1 and 10.3 of this Section.

                            SECTION 11. AMENDMENTS

     These Bylaws may be altered, amended or repealed and new Bylaws may be
adopted by the Board, except that the Board may not repeal or amend any Bylaw
that the shareholders have expressly provided, in amending or repealing such
Bylaw, may not be amended or repealed by the Board.  The shareholders may also

<PAGE>
 
and all other improvements owned by Landlord and serving the Building and the

                            ARTICLE 2:  LEASE GRANT

     Subject to and upon the terms herein set forth, Landlord leases to Tenant
and Tenant leases from Landlord the Premises, together with the right, in common
with others, to use the Common Areas.

             ARTICLE 3:  ADJUSTMENT OF COMMENCEMENT DATE/POSSESSION

3.1  COMMENCEMENT DATE

     Landlord and Tenant shall use their best efforts to complete the Building
and the Initial Tenant Improvements in accordance with Exhibit D hereto on the
Target Commencement Date or as soon thereafter as practicable.

     The determination of the Commencement Date with respect to the Initial
Premises shall depend on which contractor is selected to construct the Initial
Tenant Improvements.  If Tenant selects the contractor engaged by Landlord to
construct the shell and core of the Building (the "Shell and Core Contractor"),
Landlord shall use its commercially reasonable best efforts to cause the
Commencement Date to occur by May 21, 1999.  If the Shell and Core Contractor's
bid is the lowest received by Tenant for the construction of the Tenant
Improvements, or is within two percent (2%) of the lowest bid received, and
Tenant chooses a contractor other than the Shell and Core Contractor, the
Commencement Date shall be deemed to occur on the date that it otherwise would
have occurred had the Shell and Core Contractor been chosen to construct the
Initial Tenant Improvements (as reasonably determined based on the Shell and
Core Contractor's proposed schedule included in its tenant work bid.)  If the
Shell and Core Contractor is not the lowest bidder or within two percent (2%) of
the low bidder, and Tenant chooses such low bidder, the Commencement Date shall
be deemed to occur on the earlier of (i) the date five (5) weeks after that date
that it otherwise would have occurred had the Shell and Core Contractor been
chosen to construct the Initial Tenant Improvements (as reasonably determined
based on the Shell and Core Contractor's proposed schedule included in its
tenant work bid), or (ii) the date the Commencement Date would otherwise occur
pursuant to the

                                      -5-
<PAGE>
 
following paragraph. All of the foregoing dates are subject to the delay
provisions contained in Section 3(d) below. The contractor so selected to
construct the Tenant Improvements shall be hereinafter referred to as the
"Tenant Improvements Contractor."

     The Commencement Date with respect to the Initial Premises shall be deemed
to occur on (A) the later of (I) the completion date specified in the notice
("30 Day Notice") delivered to Tenant at least thirty (30) days prior to the
date that the Initial Premises will be completed for occupancy or (II) the date
the entirety of the Initial Premises is in fact delivered to Tenant with all of
Landlord's Work and the Initial Tenant Improvements substantially completed, or
(B) such earlier date as Landlord would have been able to so deliver the entire
Premises to Tenant but for Tenant Delay (defined below).  Subject to Tenant
Delay or other causes beyond Landlord's control, Landlord shall use its best
efforts to deliver the Premises to Tenant no later than the completion date
specified in the 30 Day Notice.  Notwithstanding the foregoing, the Commencement
Date shall be deemed to have occurred with respect to the Initial Premises on
the date Tenant first occupies the Initial Premises for normal business
operations, if such date is earlier than the dates described above.

     The Commencement Date shall not be deemed to occur until the following
conditions shall have been satisfied by Landlord:

          (1) The utility and other systems servicing the Building and necessary
for the operation of the Building or Tenant's occupancy and full enjoyment of
the Initial Premises (such as elevators, plumbing, heating, ventilating, air
conditioning, electrical and security systems) shall be completed and in good
order and operating condition except for (A) details of construction, decoration
and mechanical adjustments which do not materially interfere with Tenant's use
of the Initial Premises, and (B) any part thereof the non-completion of which
shall be due to Tenant Delay;

          (2) Landlord (A) shall have obtained a temporary Certificate of
Occupancy for the Initial Premises, or (B) would have been entitled to the
issuance of a temporary Certificate of Occupancy for the Initial Premises, but
for Tenant Delay;

          (3) The lobby of the Building and the entrances and public portions
(including the garage), stairways, corridors and elevators (including freight
elevators) of the Building, shall have been finished (except for details of
construction, decoration and mechanical adjustments which do not materially
detract from the appearance of such areas or materially interfere with their use
for normal purposes) and shall be in a clean and orderly condition affording
reasonable access to

                                      -6-
<PAGE>
 
all portions of the Initial Premises, or would be in such condition but for
Tenant Delay; and

          (4) The exterior of the Building (including the installation of glass
therein) shall have been completed except for (A) minor portions thereof which
in the aggregate do not materially affect Tenant's use of the Premises,  and (B)
any part thereof the non-completion of which shall be due to Tenant Delay.

     As used herein, the term "Tenant Delay" shall  mean, as to any delay
experienced by Landlord in its work on the Building or the Tenant Improvements,
(a) any interference or delay caused by occurrences within the reasonable
control of Tenant; (b) any delay caused by Tenant's failure or refusal to
furnish plans, or approve or disapprove plans for the Tenant Improvements,
within the periods set out in Exhibit D; (c) any delay attributable to changes
in or additions to Landlord's plans requested by Tenant or Tenant's selection of
non-Building Standard Tenant Improvements; (d) any other delay in acts of Tenant
required under Exhibit D; or (e) any delay attributable to Tenant's selection as
the Tenant Improvement Contractor of a party other than the Shell and Core
Contractor, as described in this Section 3(A); provided that the foregoing
clauses (a) through (e) shall apply only to the extent that such delay impedes
or otherwise adversely affects Landlord's work or the schedule for preparing the
Premises for occupancy.  Landlord shall notify Tenant as soon as reasonably
possible when Landlord becomes aware of an event constituting Tenant Delay.

     The occurrence of the Commencement Date prior to the completion in full of
all work required to be performed by Landlord as provided herein shall not
relieve Landlord of its obligation thereafter to complete the same with due
dispatch and in a workmanlike manner.  Without waiving any rights of Tenant,
Landlord, Tenant, and Landlord's and Tenant's architects shall prepare within
thirty (30) days after the Commencement Date or as soon thereafter as
practicable a "punch-list" which shall consist of the items that have not been,
but should have been, finished or furnished by Landlord in the Premises.  Upon
presentation of such punch-list to Landlord, Landlord shall, with all due
diligence, proceed to complete and furnish all punch-list items.  If such items
relate to shell and core work, they shall be completed at Landlord's sole cost
and expense.  If such items relate to Tenant Improvements, they shall be paid in
the same manner that the costs of Tenant Improvements are paid.  If within
thirty (30) days after presentation of the punch-list, Landlord shall not have
commenced, and be proceeding with due diligence, to complete and furnish such
items, or if Landlord thereafter fails to prosecute its work to completion with
due diligence, Tenant may deliver written notice of such failure to Landlord,
and if Landlord does not commence and proceed with due diligence to complete
such work within ten (10) days after

                                      -7-
<PAGE>
 
Landlord's receipt of such notice, Tenant may complete such items and, to the
extent Landlord is responsible for such costs as set forth above, Landlord will
reimburse Tenant upon demand for the reasonable costs incurred by Tenant for
such work. If such costs are properly chargeable to Landlord and are not paid
within ten (10) days after demand, such costs shall be credited to and deducted
from Tenant's next monthly installments of Rent and Additional Rent payable
hereunder as an offset against such amounts owing by Tenant. Any such punch-list
items which do not materially interfere with Tenant's enjoyment of the portion
of the Premises involved shall not delay the Commencement Date with respect
thereto.

     Landlord shall promptly correct all defects in Landlord's Work and Tenant
Improvement work performed by the Tenant Improvement Contractor, and all
failures of such work to conform to the plans and specifications for such work
which have been agreed upon by Landlord and Tenant, which defects or non-
conformities are discovered before or within one year after the date upon which
Tenant first occupies the Premises.  Landlord shall bear all costs of correcting
Landlord's Work and, to the extent caused by the act or omission of Landlord,
Tenant Improvement work performed by the Tenant Improvement Contractor.
Landlord and Tenant shall each give the other prompt written notice after
discovering the existence of any such defects or non-conformities in Landlord's
work and Tenant Improvement work performed by the Tenant Improvement Contractor.

3.2  DELAYS

     In the event, due to delays from any cause other than Tenant Delay or other
delays beyond the reasonable control of Landlord, the Initial Premises are not
available for occupancy by Tenant and the Commencement Date shall not have
occurred by July 1, 1999, then Landlord shall reimburse Tenant for any holdover
rent premium or other rent differential payable by Tenant in its current space
(excluding normal base rent and any consequential damages payable to Tenant's
current landlord), and Tenant shall in no event be required to pay rent
simultaneously for both its current space and the Premises, provided in no event
shall Landlord's liability as a result of such holdover exceed Forty Thousand
Dollars ($40,000) per month.  In addition, in the event, due to delays from any
cause other than Tenant Delay, the Initial Premises are not available for
occupancy by January 1, 2000, Tenant may elect, within thirty (30) days
thereafter, to terminate this Lease.

3.3. INSTALLATION PERIOD

     Tenant shall have the right to enter the Premises at no cost for up to
sixty (60) days prior to the Commencement Date for purposes of installing
furniture, fixtures, cabling, wiring and equipment (the "Installation Period"),
provided that the

                                      -8-
<PAGE>
 
Installation Period shall not delay the Commencement Date. Tenant shall
coordinate its work with the Shell and Core Contractor and the Tenant
Improvements Contractor and shall not interfere with any such contractors or
their subcontractors. Tenant shall not be charged Rent during the Installation
Period unless Tenant has occupied the Premises during such period for normal
business operations.

3.4  CONFIRMATION OF COMMENCEMENT DATE

     In the event the Commencement Date is established as a later or earlier
date than the Target Commencement Date, Landlord and Tenant shall confirm the
same in writing.

3.5  OWNERSHIP OF LAND

     Tenant is aware that as of the date this Lease is signed, Landlord does not
own the Land.  Landlord has a contractual right and obligation to purchase the
Land, and hereby represents to Tenant that Landlord shall acquire fee ownership
in the Land in sufficient time to perform all of its obligations hereunder.

                            ARTICLE 4:  TERMINATION

          A   Landlord anticipates that commencement of construction (as defined
in Section 4(B)) on the Building shall occur on or before June 15, 1998.  If
Landlord has not commenced construction of the Building by August 1, 1998, or
has not commenced construction of the Tenant Improvements by April 1, 1999,
then, in either such event, at its option, Tenant may, by notice in writing to
Landlord within thirty (30) days thereafter, terminate this Lease without any
liability whatsoever to Landlord, except that any amounts Tenant has deposited
with Landlord shall be returned to Tenant.  Termination under the preceding
sentence shall be the sole remedy at law or equity of Tenant.  In addition to
the foregoing, if Landlord has not commenced construction of the Building by
February 15, 1999 for reasons beyond the reasonable control of Landlord, either
Landlord or Tenant may, by delivery of written notice to the other, elect to
terminate this Lease without any liability to the other, except that any amounts
Tenant has deposited with Landlord shall be returned to Tenant.  Termination
under the preceding sentence shall be the sole remedy at law or equity of Tenant
or Landlord.  All of the foregoing dates shall be extended for delays caused by
Tenant Delay, but not for delays caused by Force Majeure or other causes beyond
Landlord's control.

          B.  For the purposes of this Lease, "commencement of construction,"
"commenced construction," construction has commenced," "commencement of
construction has occurred" and "commencing construction" shall mean, with
respect

                                      -9-
<PAGE>
 
to the Building, that Landlord has acquired the Land, obtained the
building permit for construction of the Building, and commenced excavation of
the underground garage (and not merely surface grading), and with respect to the
Initial Tenant Improvements, that Landlord has issued a release for construction
to the Tenant Improvements Contractor.

                              ARTICLE 5:  PREMISES

5.1  INITIAL PREMISES

     The Initial Premises are depicted on Exhibit A attached hereto and contain
approximately ninety-four thousand one hundred thirty-five (94,135) rentable
square feet of area.  The precise square footage of the Initial Premises shall
be determined during Tenant's space planning process.  The rentable area of the
Initial Premises may be increased (subject to space availability) by an amount
up to ten percent (10%) of the rentable area of the Initial Premises.  If Tenant
elects to so increase the Initial Premises, Tenant shall deliver written notice
to Landlord no later than the date four (4) months after commencement of
construction of the Building (as defined in Section 4(B) above).  Any such
increase shall be subject to Landlord's approval of Tenant's space plan for such
modified space, such approval not to be unreasonably withheld.

5.2. EXPANSION OPTION

     Landlord hereby grants Tenant an option to expand ("Expansion Option") in
accordance with the provisions of this Section 5(B).  Landlord shall provide
Tenant the option to lease between ten thousand (10,000) and twenty thousand
(20,000) rentable square feet of area in the Building contiguous to the
Premises, with such space being made first available to Tenant no sooner than
the thirtieth (30th) month of the Lease Term and no later than the forty-eighth
(48th) month of the Lease Term.  Landlord shall provide Tenant with written
notice of the availability of such space at least twelve (12) months prior to
the date such space will first be available.  Such notice shall also include the
size and location of such space and the lease terms upon which Landlord offers
such space for lease.  All such terms shall be at the fair market  rate for a
comparable lease with a comparable lease term in comparable first class
buildings in the area.  All such space shall be offered to Tenant in its
current, "as is" condition, unless such space has not been previously improved,
in which case the tenant improvement allowance provisions of Section 5(E) below
shall apply.  Tenant may elect to lease such space by delivering written notice
to Landlord no later than the date nine (9) months prior to the date such space
is available to Tenant.  Provided Landlord has delivered timely notice of the
availability of such space to Tenant, Tenant's failure to deliver such notice by
such date shall be deemed a waiver of

                                     -10-
<PAGE>
 
Tenant's election to exercise the Expansion Option. If Tenant elects to lease
such space but Landlord and Tenant are unable to agree upon the terms of such
lease by the date thirty (30) days after delivery of Tenant's notice to lease
such space, the lease terms shall be determined by arbitration in accordance
with the provisions of Section 5(C) below (except the rate so determined shall
not be a renewal rate).

5.3  OPTION TO EXTEND

     Landlord hereby grants Tenant the option to extend the Lease Term for two
(2) periods of three (3) years each, upon all of the terms and conditions
contained in this Lease, except for Base Rent.  The Base Rent shall be one
hundred percent (100%) of the projected net fair market rental rate on the
effective date of such renewal for comparable term extensions for comparable
space in comparable first class buildings in the area (the "Fair Market Renewal
Rate"), provided that in no event shall the Fair Market Renewal Rate be less
than the then current Base Rent being paid by Tenant.  If Tenant wishes to
exercise this extension option, Tenant shall provide written notice of its
intent to extend at least twelve (12) months prior to the expiration of the then
current Lease Term.  Within thirty (30) days after receipt of such notice,
Landlord shall inform Tenant of the proposed Base Rent and other extension
terms.  If Landlord and Tenant cannot agree on a Base Rent within sixty (60)
days after Tenant's receipt of Landlord's notice, then Tenant may either (i)
elect not to so extend the Lease Term; or (ii) irrevocably elect to extend the
Lease Term with the market rent to be determined in accordance with the
following binding arbitration provisions.

          (1) Within fifteen (15) days after Tenant's irrevocable election to
extend the Lease term, Landlord and Tenant shall each identify an impartial
person to act as a valuation expert and notify the other thereof.  The expert
specified in each such notice must be a commercial real estate professional
having not less than ten (10) years' active experience as a real estate
professional in the downtown and suburban office leasing market in Bellevue,
Washington.  If either party fails to appoint an expert within such fifteen (15)
day period, then the determination of the expert first appointed shall be final,
conclusive and binding on both parties.

          (2) The named experts shall together determine the Fair Market Renewal
Rate.  If the experts fail to agree on the Fair Market Renewal Rate within
thirty (30) days of their appointment and the difference in their conclusions
about Fair Market Renewal Rate is ten percent (10%) or less of the lower of the
two determinations, Fair Market Renewal Rate shall be the average of the two
determinations.

                                     -11-
<PAGE>
 
          (3) If the two experts fail to agree on Fair Market Renewal Rate and
the difference between the two determinations exceeds ten percent (10%) of the
lower of the two determinations, then the experts shall appoint a third expert,
similarly impartial and qualified, to determine the Fair Market Renewal Rate.
Such third expert shall determine the Fair Market Renewal Rate within thirty
(30) days of his or her appointment, and the average of the determinations of
the two closest experts is final, conclusive and binding on Landlord and Tenant.
Landlord and Tenant shall each execute and deliver an agreement confirming
annual rent for the extended term.

          (4) Landlord and Tenant shall each pay the fees of any expert
appointed by Landlord and Tenant, respectively, and Landlord and Tenant shall
each pay one-half ( 1/2) of the fees of the third expert, if any.

5.4  RIGHT OF FIRST OFFER

     Landlord hereby grants Tenant a continuing right of first offer in
accordance with the provisions of this Section 5(D).  Tenant shall have a right
of first offer on all space in the Building which is currently available or
which becomes available during the Lease Term.  In the event Landlord is
prepared to issue or issues a proposal to a third-party tenant for space in the
Building, or receives an unsolicited offer from a third-party tenant on terms
Landlord is willing to accept (but excluding responses to proposals of Landlord
that have already been submitted to Tenant or that are received during the 60-
day period described below), Landlord shall deliver a notice ("Landlord's
Notice") to Tenant identifying the space subject to such proposal and the lease
terms (including rent and tenant improvement allowance) that Landlord is
offering to such third-party tenant.  Tenant shall have five (5) business days
after receipt of Landlord's Notice to elect to lease such space upon the terms
and conditions contained in Landlord's Notice or, alternatively, to elect to
lease such space at the then fair market rental value for such space.  If Tenant
elects to lease such space at its then fair market rental value and Landlord and
Tenant are unable to agree on the fair market rental value of such space within
thirty (30) days after Tenant's election to lease such space, the fair market
rental value shall be determined in the same matter that the Fair Market Renewal
Rate is determined in Section C above, except the rate shall be for expansion,
as opposed to renewal, leases.  If Tenant elects not to lease such space, or if
Tenant fails to respond within such five (5) business day period, Landlord shall
be free to lease such space (including space subject to any first offer, first
refusal, expansion or option rights included in Landlord's Notice for such
third-party tenant) to another party on any terms and conditions Landlord and
such other party may agree upon.  The space addressed in Landlord's Notice shall
be resubmitted to Tenant under this Section 5(D) (i) if such space is not
leased, pursuant to a signed

                                     -12-
<PAGE>
 
lease agreement, with a party selected by Landlord within sixty (60) days after
delivery of Landlord's Notice to Tenant (i.e. the selection of the party must
occur within such 60-day period); and (ii) upon expiration of the term of the
lease, including any extensions, of the party selected by Landlord within the
60-day period after delivery of Landlord's Notice. In addition to the foregoing,
if Tenant is leasing at least one hundred thousand (100,000) square feet of
rentable space in the Campus, Tenant shall have a right of first offer on the
terms contained in this Section 5(D) over all space in Building 4 and Building 5
which is currently available or which becomes available during the Lease Term,
provided that any other tenant in Building 4 or Building 5 that leases twenty
thousand (20,000) rentable square feet or more may be granted additional (apart
from those contained in such tenant's original lease) expansion rights, first
offer rights or first refusal rights in Building 4 or Building 5 which will be
prior to Tenant's right of first offer described herein. Landlord shall notify
Tenant if any such rights are granted to other tenants.

5.5  FURTHER EXPANSIONS

     Apart from Tenant's Expansion Option and Right of First Offer described
above, if Tenant agrees to expand into and occupies any other space in the
Building, Building 4 or Building 5 prior to the end of the twelfth (12th) month
of the Lease Term, Rent for such space shall be at the same rate as Rent for the
Initial Premises, the Lease Term with respect to that expansion space shall be
coterminous with that of the Initial Premises, and the Allowance will be the
same as provided for the Initial Premises.  If Tenant expands into such other
space after the end of the twelfth (12th) month of the Lease Term, the Rent for
such space shall be at the then fair market rental rate for comparable space in
comparable buildings in the area of the Building, as Landlord and Tenant may
agree, and if the space is unimproved, Landlord shall grant Tenant an Allowance
of Thirty-Five Dollars ($35.00) per square foot of rentable area, prorated based
on the portion of the Initial Term remaining.  For example, if Tenant occupies
and commences paying rent on space at the beginning of the third (3rd) year of
the Lease Term, Tenant shall be entitled to an Allowance of $25.00 per rentable
square foot of such space ($35 x 5/7).  If such expansion space has previously
been improved, then Tenant shall take such space in an "as is" condition and no
Allowance will be granted to Tenant for such space unless otherwise agreed.
Rent shall commence on any such previously-improved space on the earlier to
occur of (i) the date four (4) weeks after such space is delivered to Tenant; or
(ii) the date Tenant occupies such space for normal business operations.

                                     -13-
<PAGE>
 
5.6  PARKING

     Landlord shall provide Tenant with no fewer than 3.4 unassigned parking
spaces in the parking garage serving the Building, and/or Buildings 4 and 5 if
Tenant has expanded into those Buildings, for each one thousand (1,000) usable
square feet of leased space in the Premises, as expanded.  The number of spaces
provided to Tenant hereunder shall change as the area of the Premises changes.
Tenant may change the number of spaces Tenant wishes to use from time to time,
subject to the above maximum, provided Tenant gives Landlord at least thirty
(30) days prior notice of such change and the changes are effective on the first
day of a calendar month.  The rate for monthly parking for each such space
during the first five (5) years of the Initial Term shall be Forty-Five Dollars
($45.00) per month per space plus Washington State sales tax, and shall be
increased, beginning in the sixth (6th) year of the Lease Term, by the same
percentage that the Index has increased since the Commencement Date.  A
designated limited number of executive parking spaces will be located directly
below the Building on the top garage level.  The exact size of this area will
depend upon how many parkers desire this service.  The cost for stalls for these
executive parking spaces will be Sixty-Five Dollars ($65.00) per month per stall
plus Washington State sales tax.  "Usable square feet" means "usable area" as
defined in BOMA.  No reserved stalls will be available.

5.7  LANDLORD'S REPRESENTATIONS AND WARRANTIES

     Landlord hereby represents and warrants to Tenant that (i) Landlord has the
current contractual right to acquire the Land; (ii) Landlord shall acquire the
Land in sufficient time for Landlord to perform all of its obligations
hereunder; (iii)Landlord has obtained Administrative Design Review for the
Building from the City of Bellevue and has submitted applications for all
building permits.

                        ARTICLE 6:  TENANT IMPROVEMENTS

          A.  Tenant Improvements for the Initial Premises ("Initial Tenant
Improvements") shall be constructed pursuant to Tenant's plans for the Premises
approved by Landlord to the extent and in the manner set forth in Exhibit D.
Landlord shall enter into the contract with the Initial Tenant Improvements
contractor, who shall be selected in accordance with the provisions of Exhibit
D.  Tenant is aware that its selection of an Initial Tenant Improvements
contractor other than the Shell and Core Contractor may result in delays in
completion of the Initial Tenant Improvements.

          B.  Landlord shall provide Tenant with an allowance ("Allowance") of
Thirty-Three Dollars ($33.00) per square foot of rentable area in the Initial

                                     -14-
<PAGE>
 
Premises.  Any unused portion of the Allowance may be taken as a credit against
Rent or may be applied to additional build-out, wiring or cabling costs, as
Tenant may elect.  Any costs of constructing Tenant Improvements in excess of
the Allowance shall be borne solely by Tenant.

          C.  Landlord and Tenant shall mutually agree on the selection of an
architect to plan, design, and complete construction documents for the Initial
Tenant Improvements.  The cost for such services (with the exception of an
initial space plan to be provided by Landlord at Landlord's expense and in
addition to the Allowance, not to exceed fifteen cents ($0.15) per rentable
square foot of the Initial Premises) as well as engineering costs attributable
to the same, shall be charged against the Allowance.

          D.  All disputes, controversies and claims arising out of or relating
to the construction of the Tenant Improvements in the Initial Premises shall be

downtown Seattle or Bellevue or the outlying Bellevue real estate markets.

6.4  APPOINTMENT OF THIRD ARBITRATOR

under Subsection 2 the two arbitrators shall appoint a third arbitrator who
shall be qualified in accordance with subsection 3.  Such third arbitrator shall
be appointed within seven (7) calendar days of receipt by the party demanding
arbitration of notice of response provided for under Subsection 3.  If the two
arbitrators fail to timely appoint a third arbitrator, the third arbitrator

or to dismiss or the like) except as may be permitted by the arbitrators; and
any such discovery or dispositive motion practice permitted by the arbitrators
shall not in any way conflict with the time limits contained herein.  The
arbitrators shall not be bound by any rules of civil procedure or evidence, but
rather shall consider such writings and oral presentations as reasonable
business persons would use in the conduct of their day to day affairs, and may
require the parties to submit some or all of their case by written declaration
or such other manner of presentation as the arbitrators may determine to be
appropriate.  It is the intention of the parties to limit live testimony and
cross examination to the extent absolutely necessary to insure a fair hearing to
the parties on significant and material issues.  Venue of any arbitration
hearing conduct pursuant to this agreement shall be in Seattle, Washington.  It
is also the intention of the parties that any such arbitration shall not
interfere with the continued construction of the Tenant Improvements, and unless
the dispute in question makes it impossible for such

                                     -16-
<PAGE>
 
construction to continue, the pending arbitration shall not affect such
construction schedule.

     The arbitrators' decision shall be made in no event later than seven (7)
calendar days of the commencement of the arbitration hearing described in
Subsection 5.  If three (3) arbitrators are appointed, a majority decision shall
prevail.  The award shall be final and judgment may be entered in any court
having jurisdiction thereof.  The arbitrators may award specific performance of
this Agreement.  The arbitrators may also require remedial measures as part of
any award.  The arbitrators may award attorneys' fees and costs to the more
prevailing party.

                               ARTICLE 7:  RENT

          A.  Tenant shall pay to Landlord, throughout the Lease Term, the Base
Rental, in equal monthly installments on the first day of each calendar month,
without demand, notice or offset.  In addition, during each calendar year, or
portion thereof, falling within the Lease Term, Tenant shall pay to Landlord as
Additional Base Rental hereunder Tenant's Pro Rata Share of Basic Costs (as
defined below) for the applicable calendar year. Prior to the Commencement Date
and prior to January 1 of each calendar year during the Lease Term, or as soon
thereafter as practical, Landlord shall make a good faith estimate of Basic
Costs for the applicable calendar year and Tenant's Pro Rata Share thereof. On
or before the first day of each month during such calendar year, Tenant shall
pay to Landlord, as Additional Base Rental, a monthly installment equal to one-
twelfth of Tenant's Pro Rata Share of Landlord's estimate of Basic Costs.
Landlord shall have the right from time to time during any such calendar year,
if it reasonably believes the costs will vary by more than five percent (5%), to
revise the estimate of Basic Costs for such year and provide Tenant with a
revised statement therefor, and thereafter the amount Tenant shall pay each
month shall be based upon such revised estimate. If Landlord does not provide
Tenant with an estimate of the Basic Costs by January 1 of any calendar year,
Tenant shall continue to pay a monthly installment based on the previous year's
estimate until such time as Landlord provides Tenant with an estimate of Basic
Costs for the current year.  Upon receipt of such current year's estimate, an
adjustment shall be made for any month during the current year with respect to
which Tenant paid monthly installments of Additional Base Rental based on the
previous year's estimate. Tenant shall pay to Landlord for any underpayment
within ten (10) days after demand. Any overpayment shall, at Landlord's option,
be refunded to Tenant or credited against the installment of Base Rental due for
the months immediately following the furnishing of such estimate. Any amounts
paid by Tenant based on any estimate shall be subject to

                                     -17-
<PAGE>
 
adjustment pursuant to the immediately following paragraph when actual Basic
Costs are determined for such calendar year.

     As soon as is practical following the end of each calendar year during the
Lease Term, Landlord shall furnish to Tenant a statement of Landlord's actual
Basic Costs for the previous calendar year. If the amount of estimated Basic
Costs actually paid by Tenant for the prior year is in excess of Tenant's actual
Pro Rata Share of Basic Costs for such prior year, then Landlord shall apply
such overpayment against Base Rental due or to become due hereunder, provided if
the Lease Term expires prior to the determination of such overpayment, Landlord
shall refund such overpayment to Tenant after first deducting the amount of any
Rent due hereunder. Likewise, Tenant shall pay to Landlord, within ten (10) days
after demand, any underpayment with respect to the prior year, whether or not
the Lease has terminated prior to receipt by Tenant of a statement for such
underpayment, it being understood that this clause shall survive the expiration
of the Lease.

     Notwithstanding the foregoing, in no event shall Controllable Operating
Costs exceed Four Dollars and Seventy-Five Cents ($4.75) per rentable square
foot per annum for 1999, nor increase by more than five percent (5%) per annum,
compounded, thereafter throughout the Initial Term.  For purposes of this
Section VI A, "Controllable Operating Costs" shall mean the total Basic Costs
less Basic Costs attributable to energy consumption (including gas, oil and
electricity), utilities and Taxes.

         B.   "Basic Costs" shall mean all reasonable and customary costs and
expenses paid or incurred in each calendar year in connection with operating,
maintaining, repairing, managing and owning the Building and the Property,
including, but not limited to, the following:

     1.  All labor costs for all persons at or below the grade of Building
manager performing services required or utilized in connection with the
operation, repair, replacement and maintenance of and control of access to the
Building and the Property, including but not limited to amounts incurred for
wages, salaries and other compensation for services, payroll, social security,
unemployment and other similar taxes, workers' compensation insurance, uniforms,
training, disability benefits, pensions, hospitalization, retirement plans,
group insurance or any other similar or like expenses or benefits.

          2.  All management fees (not to exceed 4% of gross rents), the cost of
equipping and maintaining a management office at the Building (but excluding
rent), accounting services, legal fees (subject to the exclusions described
below), and all other administrative costs relating to the Building and the
Property. If

                                     -18-
<PAGE>
 
management services are not provided by a third party, Landlord shall be
entitled to a management fee comparable to that due and payable to third parties
provided Landlord or management companies owned by, or management divisions of,
Landlord perform actual management services of a comparable nature and type as
normally would be performed by third parties.

          3.  All rental and/or purchase costs of materials, supplies, tools and
equipment used in the operation, repair, replacement and maintenance and the
control of access to the Building and the Property.

          4.  All amounts charged to Landlord by contractors and/or suppliers
for services, replacement parts, components, materials, equipment and supplies
furnished in connection with the operation, repair, maintenance, replacement of
and control of access to any part of the Building, or the Property generally,
including the heating, air conditioning, ventilating, plumbing, electrical,
elevator and other systems and equipment.  At Landlord's option, major repair
items may be amortized over their useful lives, not to exceed the Lease Term.

          5.  All premiums and deductibles paid by Landlord for fire and
extended coverage insurance, earthquake and extended coverage insurance,
liability and extended coverage insurance, rental loss insurance, elevator
insurance, boiler insurance and other insurance customarily carried from time to
time by landlords of comparable office buildings or required to be carried by
Landlord's Mortgagee.

          6.  Charges for water, gas, steam and sewer, but excluding those
charges for which Landlord is otherwise reimbursed by tenants, and charges for
Electrical Costs. For purposes hereof, the term "Electrical Costs" shall mean:
(i) all charges paid by Landlord for electricity supplied to the Building,
Property and Premises, regardless of whether such charges are characterized as
distribution charges, transmission charges, generation charges, public good
charges, disconnection charges, competitive transaction charges, stranded cost
recoveries or otherwise; and (ii) except to the extent otherwise included in
Basic Costs, any costs incurred in connection with the energy management program
for the Building, Property and Premises, including any costs incurred for the
replacement of lights and ballasts and the purchase and installation of sensors
and other energy saving equipment.  Notwithstanding the foregoing, Electrical
Costs shall be adjusted as follows: (a) any amounts received by Landlord as
reimbursement for above standard electrical consumption shall be deducted from
Electrical Costs, (b) the cost of electricity incurred in providing overtime
HVAC to specific tenants shall be deducted from Electrical Costs, it being
agreed that the electrical component of overtime HVAC Costs shall be calculated
as a reasonable percentage of the total HVAC costs charged to such tenants, and
(c) if

                                     -19-
<PAGE>
 
Tenant is billed directly for the cost of electricity to the Premises as
a separate charge in addition to Base Rental and Basic Costs, the cost of
electricity to individual tenant spaces in the Building shall be deducted from
Electrical Costs.

          7.   "Taxes", which for purposes hereof, shall mean:  (a) all real
estate taxes and assessments on the Property, the Building or the Premises, and
taxes and assessments levied in substitution or supplementation in whole or in
part of such taxes, (b) all personal property taxes for the Building's personal
property, including license expenses, (c) all taxes imposed on services of
Landlord's agents and employees, (d) all other taxes, fees or assessments now or
hereafter levied by any governmental authority on the Property, the Building or
its contents or on the operation and use thereof (except as relate to specific
tenants), and (e) all costs and fees incurred in connection with seeking
reductions in or refunds in Taxes including, without limitation, any costs
incurred by Landlord to challenge the tax valuation of the Building, but
excluding income or franchise taxes.  For the purpose of determining real estate
taxes and assessments for any given calendar year, the amount to be included in
Taxes for such year shall be as follows:  (1) with respect to any special
assessment that is payable in installments, Taxes for such year shall include
the amount of the installment (and any interest) due and payable during such
year; and (2) with respect to all other real estate taxes, Taxes for such year
shall  include the amount due and payable for such year.  If a reduction in
Taxes is  obtained for any year of the Lease Term during which Tenant paid its
Pro Rata Share of Basic Costs, then Basic Costs for such year will be
retroactively adjusted and Landlord shall provide Tenant with a credit, if any,
based on such adjustment.

          8.   All landscape expenses and costs of maintaining, repairing,
resurfacing and striping of the parking areas and garages of the Property and
the Campus.

          9.   Cost of all maintenance service agreements, including those for
equipment, alarm service, window cleaning, drapery or venetian blind cleaning,
janitorial services, pest control, uniform supply, plant maintenance,
landscaping, and any parking equipment.

          10.  Cost of all other repairs, replacements and general maintenance
of the Property and Building neither specified above nor directly billed to
tenants, and all similar common area costs of the Campus allocable to the
Building.

          11.  The amortized cost of capital improvements made to the Building
or the Property after the Commencement Date which are:  (a) primarily for the
purpose of reducing operating expense costs or otherwise improving the operating
efficiency of the Property or Building; or (b) required to comply with any laws,
rules 

                                     -20-
<PAGE>
 
or regulations of any governmental authority enacted after the Commencement Date
or a requirement of Landlord's insurance carrier enacted after the Commencement
Date. At Landlord's option, the cost of such capital improvements shall be
amortized over their useful lives (not to exceed the Lease Term) and shall, at
Landlord's option, include interest at a rate that is reasonably equivalent to
the interest rate that Landlord would be required to pay to finance the cost of
the capital improvement in question as of the date such capital improvement is
performed, provided if the payback period for any capital improvement is less
than five (5) years, Landlord may amortize the cost of such capital improvement
over the payback period.

          12.  All common area costs of the Campus, including, without
limitation Taxes, allocable to the Property through recorded covenants or
otherwise.

          13.  Any other expense or charge of any nature whatsoever which, in
accordance with general industry practice with respect to the operation of a
first-class office building, would be construed as an operating expense.  Basic
Costs shall not include (I) costs of any special services rendered to individual
tenants for which a separate charge is collected; (II) leasing commissions and
other leasing expenses; (III) the cost of capital improvements (except as set
forth above); (IV) executives' salaries above the grade of Building manager; (V)
amounts received by Landlord through proceeds of insurance to the extent the
proceeds are compensation for expenses which were previously included in Basic
Costs hereunder; (VI) cost of repair or replacements incurred by reason of fire
or other casualty or by the exercise of the right of eminent domain; (VII)
consulting fees, marketing fees, advertising and promotional expenditures;
(VIII) legal fees in connection with the negotiation and preparation of leases
of space or legal fees in connection with the sale of all or any portion of the
Building in which the Premises are located, or an interest therein, or the
financing or refinancing of Landlord's interest in all or any portion of the
Building in which the Premises are located, or in connection with disputes with
tenants, and legal and auditing fees, other than legal and auditing fees
reasonably incurred in connection with the maintenance and operation of all or
any portion of such Building or in connection with the preparation of the
statements required pursuant to additional rent or lease escalation provisions
contained in leases of space in such Building; (IX) depreciation or loan
payments; (X) costs resulting from the correction of any latent construction
defects in all or any portion of the Premises or Building; (XI) penalties due to
any violation of law by Landlord or other tenants; (XII) costs of preparing
tenant space for tenant occupancy; (XIII) costs allocable to properties in which
Landlord has an interest other than the Building; (XIV) damages incurred by
Landlord for any default, breach, claim, judgment or settlement; and (XV)
structural replacements (including replacements to the roof and foundations).If
the Building is not at least ninety-five percent (95%) occupied during any
calendar year of the Lease 

                                     -21-
<PAGE>
 
Term or if Landlord is not supplying services to at least ninety-five percent
(95%) of the total Rentable Area of the Building at any time during any calendar
year of the Lease Term, actual Basic Costs for purposes hereof shall, at
Landlord's option, be determined as if the Building had been ninety-five percent
(95%) occupied and Landlord had been supplying services to ninety-five percent
(95%) of the Rentable Area of the Building during such year. Any necessary
extrapolation of Basic Costs under this Article shall be performed by adjusting
the cost of those components of Basic Costs that are impacted by changes in the
occupancy of the Building (including, at Landlord's option, Taxes) to the cost
that would have been incurred if the Building had been ninety-five percent (95%)
occupied and Landlord had been supplying services to ninety-five percent (95%)
of the Rentable Area of the Building. In no event shall Landlord be entitled to
collect more than the actual Basic Costs incurred.

          C.  Tenant, within ninety (90) days after receiving Landlord's
statement of actual Basic Costs for a particular calendar year, shall have the
right to provide Landlord with written notice (the "Review Notice") of its
intent to review Landlord's books and records relating to the Basic Costs for
such calendar year.  Within a reasonable time after receipt of a timely Review
Notice, Landlord shall make such books and records available to Tenant or
Tenant's agent for its review at either Landlord's home office or at the office
of the Building, provided that if Tenant retains an agent to review Landlord's
books and records for any calendar year, such agent must be CPA firm licensed to
do business in the state in which the Building is located.  Tenant shall be
solely responsible for any and all costs, expenses and fees incurred by Tenant
or Tenant's agent in connection with such review, provided that if such review
determines that Basic Costs were overstated by ten percent (10%) or more,
Landlord shall pay the cost of such review.  If Tenant elects to review
Landlord's books and records, within thirty (30) days after such books and
records are made available to Tenant, Tenant shall have the right to give
Landlord written notice stating in reasonable detail any objection to Landlord's
statement of actual Basic Costs for such calendar year.  If Tenant fails to give
Landlord written notice of objection within such thirty (30) day period or fails
to provide Landlord with a Review Notice within the ninety (90) day period
provided above, Tenant shall be deemed to have approved Landlord's statement of
Basic Costs in all respects and shall thereafter be barred from raising any
claims with respect thereto.  Upon Landlord's receipt of a timely objection
notice from Tenant, Landlord and Tenant shall work together in good faith to
resolve the discrepancy between Landlord's statement and Tenant's review.  If
Landlord and Tenant determine that Basic Costs for the calendar year in question
are less than reported, Landlord shall provide Tenant with a credit against
future Base Rental in the amount of any overpayment by Tenant.  Likewise, if
Landlord and Tenant determine that Basic Costs for the calendar year in question
are greater than reported, Tenant shall forthwith pay to Landlord the amount of
underpayment by Tenant.  Any 

                                     -22-
<PAGE>
 
information obtained by Tenant pursuant to the provisions of this Section shall
be treated as confidential. Notwithstanding anything herein to the contrary,
Tenant shall not be permitted to examine Landlord's books and records or to
dispute any statement of Basic Costs unless Tenant has paid to Landlord the
amount due as shown on Landlord's statement of actual Basic Costs, said payment
being a condition precedent to Tenant's right to examine Landlord's books and
records.

          D.  Tenant covenants and agrees to pay to Landlord during the Lease
Term, without any setoff or deduction whatsoever except as otherwise set forth
in this Lease, the full amount of all Base Rental and Additional Base Rental due
hereunder.  In addition, Tenant shall pay and be liable for, as additional rent,
all rental, sales and use taxes or other similar taxes, if any, levied or
imposed by any city, state, county or other governmental body having authority,
such payments to be in addition to all other payments required to be paid to
Landlord by Tenant under the terms and conditions of this Lease.  Any such
payments shall be paid concurrently with the payments of the Rent on which the
tax is based.  The Base Rental, Tenant's Pro Rata Share of Basic Costs and any
recurring monthly charges due hereunder shall be due and payable in advance on
the first day of each calendar month during the Lease Term without demand,
provided that the installment of Base Rental for the first full calendar month
of the Lease Term shall be payable two (2) days after Landlord gives Tenant the
30-Day Notice described in Section 3(A) above.  All other items of Rent shall be
due and payable by Tenant on or before ten (10) days after billing by Landlord.
If the Lease Term commences on a day other than the first day of a calendar
month, then the monthly Base Rental and Tenant's Pro Rata Share of Basic Costs
for such month shall be prorated for the number of days in such month occurring
within the Lease Term based on a fraction, the numerator of which is the number
of days of the Lease Term that fell within such calendar month and the
denominator of which is the number of days in such month.  All such payments
shall be by a good and sufficient check in lawful money of the United States.
No payment by Tenant or receipt or acceptance by Landlord of a lesser amount
than the correct amount of Rent due under this Lease shall be deemed to be other
than a payment on account of the earliest Rent due hereunder, nor shall any
endorsement or statement on any check or any letter accompanying any check or
payment be deemed an accord and satisfaction, and Landlord may accept such check
or payment without prejudice to Landlord's right to recover the balance or
pursue any other available remedy.  The acceptance by Landlord of any Rent on a
date after the due date of such payment shall not be construed to be a waiver of
Landlord's right to declare a default for any other late payment.  Tenant's
covenant to pay Rent shall be independent of every other covenant set forth in
this Lease.

                                     -23-
<PAGE>
 
          E.  All Rent not paid within five (5) days of the date it is due and
payable shall bear interest from the date due until paid at fourteen percent
(14%) per annum.  In addition, if Tenant fails to pay any installment of Rent
within five (5) days after receipt of written notice that it is overdue and
payable hereunder, a service fee equal to four percent (4%) of such unpaid
amount will be due and payable immediately by Tenant to Landlord.

          F.  In lieu of requiring Tenant to pay Rent by good and sufficient
check in the manner described in Section 7(D). above, and subject to Tenant's
approval (which may be withheld in Tenant's sole discretion),Tenant shall pay
Rent by means of an automated debit system (the "Automatic Debit System")
whereby any or all payments of Rent shall be debited from Tenant's account in a
bank or financial institution designated by Tenant and credited to Landlord's
account in a bank or financial institution designated by Landlord.  In the event
Landlord elects to have Tenant pay all or any portion of Rent by means of the
Automatic Debit System, Tenant, within thirty (30) days after written request by
Landlord, shall execute and deliver to Landlord any authorizations, certificates
or other documentation as may be required to establish and give effect to the
Automatic Debit System.  If Landlord elects to have less than all items of Rent
paid by the Automatic Debit System, Landlord shall advise Tenant in writing as
to those items of Rent that will be paid by the Automatic Debit System (e.g.
Base Rental only or Base Rental and Tenant's Pro Rata Share of Basic Costs
only).  Either party shall have the right to change its bank or financial
institution from time to time, provided that Tenant, no less than thirty (30)
days prior to the effective date of any such change, shall provide Landlord with
written notice of such change and any and all authorizations, certificates or
other documentation as may be required to establish and give effect to the
Automatic Debit System at Tenant's new bank or financial institution.  Tenant
shall promptly pay all service fees and other charges imposed upon Landlord or
Tenant in connection with the Automatic Debit System, including, without
limitation, any charges resulting from insufficient funds in Tenant's bank
account.  In the event that any Rent is not paid on time as a result of
insufficient funds in Tenant's account, Tenant shall be liable for any interest
and/or service fee in accordance with Section 7(E). above.  Tenant shall remain
liable to Landlord for all payments of Rent due hereunder regardless of whether
Tenant's account is incorrectly debited in any given month, it being agreed that
a debit of less than the full amount of Rent due shall not be construed as a
waiver by Landlord of its right to receive any unpaid balance of Rent.

                                ARTICLE 8:  USE

     The Premises shall be used for the Permitted Use and for no other purpose.
Tenant agrees not to use or permit the use of the Premises for any purpose which
is 

                                     -24-
<PAGE>
 
illegal, dangerous to life, limb or property or which, in Landlord's reasonable
opinion, creates a nuisance or which would increase the cost of insurance
coverage with respect to the Building. Tenant shall conduct its business and
control its agents, servants, contractors, employees, customers, licensees, and
invitees in such a manner as not to interfere with, annoy or disturb other
tenants, or in any way interfere with Landlord in the management and operation
of the Building. Tenant will maintain the Premises in a clean and healthful
condition, and comply with all laws, ordinances, orders, rules and regulations
of any governmental entity with reference to the operation of Tenant's business
and to the use, condition, configuration or occupancy of the Premises, including
without limitation, the Americans with Disabilities Act (collectively referred
to as "Laws"). Landlord will maintain the Building and the Common Areas in a
clean and healthful condition, and comply with all laws, ordinances, orders,
rules and regulations of any governmental entity with reference to the use,
condition, configuration or occupancy of the Building, including without
limitation, the Laws. Tenant, within ten (10) days after receipt thereof, shall
provide Landlord with copies of any notices it receives with respect to a
violation or alleged violation of any Laws. Tenant will comply with the rules
and regulations of the Building attached hereto as Exhibit B and such other
rules and regulations adopted and altered by Landlord from time to time and will
cause all of its agents, servants, contractors, employees, customers, licensees
and invitees to do so. All changes to such rules and regulations will be
reasonable and shall be sent by Landlord to Tenant in writing.

                         ARTICLE 9:  SECURITY DEPOSIT

          A.  Tenant shall deposit with Landlord the following amounts on the
dates set forth below to serve as a security deposit under this Lease
(collectively the "Security Deposit"):

              1.  $250,000 on or before October 1, 1998;

              2.  An additional $500,000 on or before April 1, 1999; and

              3.  An additional $250,000 on the Commencement Date, provided that
if on the Commencement Date Tenant can demonstrate to Landlord's reasonable
satisfaction that Tenant then has Working Capital reserves of at least
$2,000,000, the requirement to make such final $250,000 deposit shall be waived.

          B.  As used herein, "Working Capital" means from time to time the
amount determined by subtracting the aggregate of all current liabilities,
accounts payable and accrued expenses of Tenant from the aggregate of Tenant's
cash, cash equivalent assets and accounts receivable that are reasonably
expected to be collected 

                                     -25-
<PAGE>
 
within ninety (90) days from the date of such determination. For purposes of
this definition, deferred revenue shall not be considered a current liability.

          C.  All such deposits constituting the Security Deposit shall be made
in the form of cash or in the form of a letter of credit issued by a financial
institution, and upon such terms, as may be reasonably approved by Landlord.
Any letter of credit delivered by Tenant shall have a minimum term of one (1)
year, and shall be renewed by Tenant on an annual basis for so long as Tenant
elects to deposit a letter of credit instead of cash hereunder.  If Landlord is
not provided notice of such renewal at least fifteen (15) days prior to the
expiration date of the then-current letter of credit, Landlord may draw down the
entire amount of the current letter of credit.  Without limiting the foregoing,
the issuing bank must have assets of at least $100,000,000, and such letter of
credit must be irrevocable and subject to no conditions other than Landlord's
presentation thereof to the issuing bank with a demand for payment that
certifies that an Event of Default (as defined in this Lease) has occurred under
this Lease and that Landlord is entitled to draw on the letter of credit in
accordance with and pursuant to this Lease.

          D.  Once established, the Security Deposit shall be reduced by twenty
percent (20%) of its maximum balance on each of the first through fifth
anniversaries of the Commencement Date, provided that on each such anniversary
date Tenant has Working Capital of at least $2,000,000.  Such reduction shall be
cumulative, so that if a reduction is not made in one year but is made in the
subsequent year, the reduction in the second year shall be forty percent (40%)
of the maximum amount of the Security Deposit.  In no event shall a reduction in
the Security Deposit be made if Tenant is then in default hereunder or if there
exists a state of circumstances which with the giving of notice or passage of
time or both would constitute a default hereunder.  Provided Tenant is not in
default at the end of the fifth (5th) year of the Lease Term, Tenant shall have
no further obligation to make the Security Deposit for the remainder of the
Lease Term, and Landlord shall return the Security Deposit to Tenant, regardless
of the level of Tenant's Working Capital at such date.

          E.  The Security Deposit shall, to the extent such deposit is made in
cash, be held by Landlord in an interest-bearing account reasonably satisfactory
to Tenant (and any interest which accrues thereon shall be disbursed to Tenant
at least on an annual basis) and as security for the performance of Tenant's
obligations under this Lease.  All such interest shall be taxable income of
Tenant.  The Security Deposit shall not be considered an advance payment of Rent
or a measure of Tenant's liability for damages.  Landlord may, from time to time
after an Event of Default, without prejudice to any other remedy, use all or a
portion of the Security Deposit to make 

                                     -26-
<PAGE>
 
good any arrearage of Rent, to repair damages to the Premises, to clean the
Premises upon termination of this Lease or otherwise to satisfy any other
covenant or obligation of Tenant hereunder. Following any such application of
the Security Deposit, Tenant shall pay to Landlord on demand (or deliver a
replacement letter of credit) the amount so applied in order to restore the
Security Deposit to its original amount. If Tenant is not in default at the
termination of this Lease, after Tenant surrenders the Premises to Landlord in
accordance with this Lease and all amounts due Landlord from Tenant are finally
determined and paid by Tenant or through application of the Security Deposit,
the balance of the Security Deposit remaining after any such application shall
be returned to Tenant. If Landlord transfers its interest in the Premises during
the Lease Term, Landlord shall assign the Security Deposit to the transferee and
thereafter shall have no further liability for the return of such Security
Deposit. Tenant agrees to look solely to such transferee or assignee for the
return of the Security Deposit. Landlord and its successors and assigns shall
not be bound by any actual or attempted assignment or encumbrance of the
Security Deposit by Tenant, provided, however, if Tenant's interest in this
Lease has been assigned, Landlord shall, provided that Landlord has been
furnished with a fully executed copy of the agreement assigning such Security
Deposit, return the Security Deposit to such assignee in accordance with the
terms and conditions hereof. If Landlord returns the Security Deposit to
Tenant's assignee as aforesaid, Landlord will have no further obligation to any
party with respect thereto. Landlord shall not be required to keep the Security
Deposit separate from its other accounts. In no event shall the Security Deposit
serve as a limitation on the damages payable by Tenant as a result of its
default under this Lease.

               ARTICLE 10:  SERVICES TO BE FURNISHED BY LANDLORD

          A.  Landlord, as part of Basic Costs (except as otherwise provided),
agrees to furnish Tenant the following services:

               1.  Hot and cold water for use in the lavatories on the floor(s)
on which the Premises is located. If Tenant desires water in the Premises for
any approved reason, including a private lavatory or kitchen, cold water shall
be supplied, at Tenant's sole cost and expense, from the Building water main
through a line and fixtures installed at Tenant's sole cost and expense with the
prior reasonable consent of Landlord. If Tenant desires hot water in the
Premises, Tenant, at its sole cost and expense and subject to the prior
reasonable consent of Landlord, may install a hot water heater in the Premises.
Tenant shall be solely responsible for maintenance and repair of any such hot
water heater.

               2.  Central heat, ventilating and air conditioning in season
during Normal Business Hours, at such temperatures and in such amounts as are
considered by Landlord, in its reasonable judgment, to be standard for first-
class

                                     -27-
<PAGE>
 
office buildings of similar class, size, age and location, or as required by
governmental authority. In the event that Tenant requires central heat,
ventilation or air conditioning at hours other than Normal Business Hours, such
central heat, ventilation or air conditioning shall be furnished only upon the
request of Tenant (which may be by telephone or in person) delivered to Landlord
at the office of the Building prior to 3:00 p.m. of the same day. Tenant shall
pay Landlord, as Additional Base Rental, the actual direct utility costs of
additional service and a reasonable charge for the extra wear and tear on
Building equipment, provided such charge shall not exceed fifteen percent (15%)
of the actual direct utility costs of such additional service.

          3.  Maintenance and repair of all Common Areas in the manner and to
the extent reasonably deemed by Landlord to be standard for first-class office
buildings of similar class, size, age and location.

          4.  Janitorial services, consistent with those provided to other first
class office buildings in Bellevue, Washington, Monday through Friday nights;
provided, however, if Tenant's use, floor covering or other improvements require
special services, Tenant shall pay the additional cost reasonably attributable
thereto as Additional Base Rental.  Landlord shall attempt to have such
janitorial services provided between 6:00 p.m. and 10:00 p.m.  Landlord shall
also use its commercially reasonable best efforts to implement a recycling
program.

          5.  Passenger elevator service in common with other tenants of
the Building.

          6.  Electricity to the Premises for general office use, in accordance
with and subject to the terms and conditions set forth in Article 14 of this
Lease.

          7.  Landlord shall provide, at Landlord's expense, a multi-level card
key security system that will control access to the Building and the garage and
elevators therein.  Tenant shall have access to the Premises 24 hours a day, 7
days a week.  Additional card readers may be installed in the stairwells to
facilitate controlled access between Tenant's floors by way of the stairwells.
Tenant shall bear the cost of any such additional card readers or other security
measures.

     B.  The failure by Landlord to any extent to furnish, or the
interruption or termination of, any services in whole or in part, resulting from
adherence to laws, regulations and administrative orders, wear, use, repairs,
improvements, alterations or any causes beyond the reasonable control of
Landlord shall not render Landlord liable in any respect nor be construed as a
constructive 

                                     -28-
<PAGE>
 
eviction of Tenant, nor give rise to an abatement of Rent, nor relieve Tenant
from the obligation to fulfill any covenant or agreement hereof, provided that
if any such interruption or termination continues for seventy-two (72) hours,
Rent shall thereafter abate to the extent the Premises are rendered untenantable
as a result thereof. Should any of the equipment or machinery used in the
provision of such services for any cause cease to function properly, Landlord
shall use reasonable diligence to repair such equipment or machinery.

          C.  Tenant expressly acknowledges that if Landlord, from time to time,
elects to provide security services, Landlord shall not be deemed to have
warranted the efficiency of any security personnel, service, procedures or
equipment and Landlord shall not be liable in any manner for the failure of any
such security personnel, services, procedures or equipment to prevent or
control, or apprehend anyone suspected of personal injury, property damage or
any criminal conduct in, on or around the Property.

          D.  Landlord shall engage Wright Runstad Associates Limited
Partnership as the manager of the Building for at least two (2) years after the
Commencement Date.

                      ARTICLE 11:  LEASEHOLD IMPROVEMENTS

     Any trade fixtures, unattached and movable equipment or furniture, or other
personalty brought into the Premises by Tenant ("Tenant's Property") shall be
owned and insured by Tenant.  Tenant shall remove all such Tenant's Property
from the Premises in accordance with the terms of Article 37 hereof.  Any and
all alterations, additions and improvements to the Premises, including any
built-in furniture (collectively, "Leasehold Improvements") shall be owned and
insured by Landlord and shall remain upon the Premises, all without
compensation, allowance or credit to Tenant.  Landlord may, nonetheless, if
Landlord so notifies Tenant at the time of initial consent to Tenant's plans,
require Tenant to remove any Leasehold Improvements performed by or for the
benefit of Tenant and all electronic, phone and data cabling as are designated
by Landlord (the "Required Removables") at Tenant's sole cost.  In the event
that Landlord so elects, Tenant shall remove such Required Removables prior to
the expiration or earlier termination of this Lease or Tenant's right to
possession. In addition to Tenant's obligation to remove the Required
Removables, Tenant shall repair any damage caused by such removal and perform
such other work as is reasonably necessary to restore the Premises to a "move
in" condition.  If Tenant fails to remove any specified Required Removables or
to perform any required repairs and restoration within the time period specified
above, Landlord, at Tenant's sole cost and expense, may remove, store, sell
and/or dispose of the Required Removables and perform such required repairs and
restoration work.  

                                     -29-
<PAGE>
 
Tenant, within five (5) days after demand from Landlord, shall reimburse
Landlord for any and all reasonable costs incurred by Landlord in connection
with the Required Removables.

                             ARTICLE 12:  SIGNAGE

     Tenant shall be entitled to install two (2) signs on the exterior of the
Building, provided such sign complies with the Signage Criteria attached as
Exhibit E hereto and with all applicable laws and codes.  The cost of such
exterior sign shall be borne by Tenant, which Tenant may pay from the Allowance.
Landlord shall provide Tenant identification on the Building directory, at
Landlord's expense.  So long as Tenant leases one hundred percent (100%) of the
Building, Tenant shall be entitled to place an additional sign bearing its name
above the main entrance to the Building, provided such sign complies with the
signage criteria attached hereto as Exhibit E and with all applicable laws and
codes.  Tenant shall have first choice of the signage locations on the Building
exterior, which locations may be on the South and West facades of the Building,
as depicted on Exhibit E.

                      ARTICLE 13:  REPAIRS AND ALTERATIONS

          A.  Except to the extent such obligations are imposed upon Landlord
hereunder, Tenant, at its sole cost and expense, shall perform all maintenance
and repairs to the Premises as are necessary to keep the same in good condition
and repair throughout the entire Lease Term, reasonable wear and tear excepted.
Tenant's repair and maintenance obligations with respect to the Premises shall
include, without limitation, any necessary repairs with respect to:  (1) any
carpet or other floor covering, (2) any interior partitions, (3) any doors, (4)
the interior side of any demising walls, (5) any telephone and computer cabling
that serves Tenant's equipment exclusively, (6) any supplemental air
conditioning units, private showers and kitchens, including any plumbing in
connection therewith, and similar facilities serving Tenant exclusively, and (7)
any alterations, additions or improvements performed by contractors retained by
Tenant.  All such work shall be performed in accordance with Section 13(B) below
and the rules, policies and procedures reasonably enacted by Landlord from time
to time for the performance of work in the Building.  If Tenant fails to make
any necessary repairs to the Premises within a reasonable time after written
notice from Landlord (except in case of emergency), Landlord may, at its option,
make such repairs, and Tenant shall pay the cost thereof to the Landlord on
demand as Additional Base Rental, together with an administrative charge in an
amount equal to ten percent (10%) of the cost of such repairs.  Landlord shall,
at its expense (except as included in Basic Costs), keep and maintain in good
repair and working order and make all repairs to and perform necessary
maintenance 

                                     -30-
<PAGE>
 
upon: (a) all structural elements of the Building (including the roof and roof
membrane, and foundations); and (b) all elevator, mechanical, electrical and
plumbing systems that serve the Building in general; and (c) the Common Areas
and Building facilities common to all tenants including, but not limited to, the
ceilings, walls and floors in the Common Areas.

          B.  Tenant shall not make or allow to be made any alterations,
additions or improvements to the Premises without first obtaining the written
consent of Landlord in each such instance, which consent Landlord shall not
unreasonably withhold.  Landlord's consent shall be deemed granted if Landlord
does not respond to Tenant's written request for approval within ten (10)
business days.  Tenant shall be obligated to remove non-Building Standard items
only if Landlord specifically requires such removal in writing at the time
Landlord approves the improvements or alterations incorporating such items.
Prior to commencing any such work and as a condition to obtaining Landlord's
consent, Tenant must furnish Landlord with plans and specifications reasonably
acceptable to Landlord; names and addresses of contractors reasonably acceptable
to Landlord; copies of contracts; necessary permits and approvals; evidence of
contractor's and subcontractor's insurance in accordance with Section 19(B)
hereof; and payment bond or other security, all in form and amount satisfactory
to Landlord.  All such improvements, alterations or additions shall be
constructed in a good and workmanlike manner using Building Standard materials
or other new materials of equal or greater quality.  Landlord, to the extent
reasonably necessary to avoid any disruption to the tenants and occupants of the
Building, shall have the right to designate the time when any such alterations,
additions and improvements may be performed and to otherwise designate
reasonable rules, regulations and procedures for the performance of work in the
Building.  Upon completion, Tenant shall furnish "as-built" plans, contractor's
affidavits and full and final waivers of lien and receipted bills covering all
labor and materials.  All improvements, alterations and additions shall comply
with all insurance requirements, codes, ordinances, laws and regulations,
including without limitation, the Americans with Disabilities Act.  Tenant shall
reimburse Landlord upon demand as Additional Base Rental for all sums, if any,
expended by Landlord for third party examination of the architectural,
mechanical, electric and plumbing plans for any alterations, additions or
improvements.  In addition, if Landlord so requests, Landlord shall be entitled
to oversee the construction of any alterations, additions or improvements that
may affect the structure of the Building or any of the mechanical, electrical,
plumbing or life safety systems of the Building.  In the event Landlord elects
to oversee such work, Landlord shall be entitled to receive a fee for such
oversight in an amount equal to the actual time reasonably spent by Landlord's
engineers at a rate of $150 per hour.  Landlord's approval of Tenant's plans and
specifications for any work performed for or on behalf of Tenant shall not be
deemed to be a representation by Landlord that 

                                     -31-
<PAGE>
 
such plans and specifications comply with applicable insurance requirements,
building codes, ordinances, laws or regulations or that the alterations,
additions and improvements constructed in accordance with such plans and
specifications will be adequate for Tenant's use.

     Notwithstanding the foregoing, Tenant may make nonstructural alterations,
additions or improvements to the interior of the Premises, including wiring
within the Premises, nonstructural partitioning, and painting and redecorating,
without the necessity of obtaining Landlord's consent, provided in all such
cases (other than cabling, painting or decoration solely within the Premises)
Tenant shall give Landlord five (5) business days' prior written notice of such
modifications.  Any such alterations, additions or improvements shall be
installed by Tenant at its sole cost and in compliance with all laws, orders and
regulations of any applicable governing body and Tenant at its expense shall
furnish to Landlord drawings for such work to enable the Building's record
drawings to be updated to reflect such changes.

               ARTICLE 14:  USE OF ELECTRICAL SERVICES BY TENANT

          A.  All electricity used by Tenant in the Premises shall be paid for
by Tenant by a separate charge billed directly to Tenant by Landlord and payable
by Tenant as Additional Base Rental within ten (10) days after billing.  It is
understood that electrical service to the Premises may be furnished by one or
more companies providing electrical generation, transmission and/or distribution
services and that the cost of electricity may be billed as a single charge or
divided into and billed in a variety of categories such as distribution charges,
transmission charges, generation charges, public good charges or other similar
categories.  Landlord shall have the exclusive right to select the company(ies)
providing electrical service to the Building, Premises and Property, to
aggregate the electrical service for the Building, Premises and Property with
other buildings, to purchase electricity for the Building, Premises and Property
through a broker and/or buyers group and to change the providers and/or manner
of purchasing electricity from time to time.

          B.  Tenant's use of electrical service in the Premises shall not
exceed, either in voltage, rated capacity, or overall load, the design
specifications for the Building as determined in Exhibit F attached hereto.  In
the event Tenant shall consume (or request that it be allowed to consume)
electrical service in excess of the design specifications set out on Exhibit F,
Landlord may refuse to consent to such excess usage or may condition its consent
to such excess usage upon such conditions as Landlord reasonably elects
(including the installation of utility service upgrades, submeters, air handlers
or cooling units), and all such additional usage (to the extent permitted by
law), installation and maintenance thereof shall be paid for by Tenant as
Additional Base Rental. Landlord, at any time during the Lease Term, shall have
the 

                                     -32-
<PAGE>
 
right to separately meter electrical usage for the Premises or to measure
electrical usage by survey or any other method that Landlord, in its reasonable
judgment, deems to be appropriate.

          C.  Notwithstanding Section A above to the contrary, if Landlord
permits Tenant to purchase electrical power for the Premises from a provider
other than Landlord's designated company(ies), such provider shall be considered
to be a contractor of Tenant and Tenant shall indemnify and hold Landlord
harmless from such provider's acts and omissions while in, or in connection with
their services to, the Building or Premises in accordance with the terms and
conditions of Article 18.  In addition, at the request of Landlord, Tenant shall
allow Landlord to purchase electricity from Tenant's provider at Tenant's rate
or at such lower rate as can be negotiated by the aggregation of Landlord's and
Tenant's requirements for electricity power.

                        ARTICLE 15:  ENTRY BY LANDLORD

     Landlord and its agents or representatives shall have the right to enter
the Premises to inspect the same, or to show the Premises to prospective
purchasers, mortgagees, tenants (during the last twelve months of the Lease Term
or earlier in connection with a potential relocation) or insurers, or to clean
or make repairs, alterations or additions thereto, including any work that
Landlord deems necessary for the safety, protection or preservation of the
Building or any occupants thereof, or to facilitate repairs, alterations or
additions to the Building or any other tenants' premises.  Except for any entry
by Landlord in an emergency situation or to provide normal cleaning and
janitorial service, Landlord shall provide Tenant with reasonable prior notice
of any entry into the Premises, which notice may be given verbally.  If
reasonably necessary for the protection and safety of Tenant and its employees,
Landlord shall have the right to temporarily close the Premises to perform
repairs, alterations or additions in the Premises, provided that Landlord shall
use reasonable efforts to perform all such work on weekends and after Normal
Business Hours.  Entry by Landlord hereunder shall not constitute a constructive
eviction or entitle Tenant to any abatement or reduction of Rent by reason
thereof.

                    ARTICLE 16:  ASSIGNMENT AND SUBLETTING

          A.  Tenant shall not assign, sublease, transfer or encumber this Lease
or any interest therein or grant any license, concession or other right of
occupancy of the Premises or any portion thereof or otherwise permit the use of
the Premises or any portion thereof by any party other than Tenant (any of which
events is hereinafter called a "Transfer") without the prior written consent of
Landlord, which consent shall not be unreasonably withheld with respect to any
proposed assignment or subletting.  

                                     -33-
<PAGE>
 
Landlord's consent shall not be considered unreasonably withheld if: (1) the
proposed transferee's financial responsibility does not meet the same criteria
Landlord uses to select Building tenants; (2) the proposed transferee's business
is not suitable for the Building considering the business of the other tenants
or would result in a violation of an exclusive right granted to another tenant
in the Building; (3) the proposed use is different than the Permitted Use; (4)
the proposed transferee is a government agency; (5) Tenant is in Default; or (6)
any portion of the Building or Premises would become subject to additional or
different governmental laws or regulations as a consequence of the proposed
Transfer and/or the proposed transferee's use and occupancy of the Premises in a
way that would have a material adverse effect on the Premises or Building.
Tenant acknowledges that the foregoing is not intended to be an exclusive list
of the reasons for which Landlord may reasonably withhold its consent to a
proposed Transfer. Any attempted Transfer in violation of the terms of this
Article shall, at Landlord's option, be void. Consent by Landlord to one or more
Transfers shall not operate as a waiver of Landlord's rights as to any
subsequent Transfers. In addition, Tenant shall not, without Landlord's consent,
publicly advertise the proposed rental rate for any Transfer.

          B.  Notwithstanding the foregoing, Tenant may assign this Lease or
sublet all or any portion of the Premises to any subsidiary or affiliate of
Tenant, provided that Tenant shall not be released from of its obligations under
this Lease.

          C.  If Tenant requests Landlord's consent to a Transfer, Tenant,
together with such request for consent, shall provide Landlord with the name of
the proposed transferee and the nature of the business of the proposed
transferee, the term, use, rental rate and all other material terms and
conditions of the proposed Transfer, including, without limitation, a copy of
the proposed assignment, sublease or other contractual documents and evidence
satisfactory to Landlord that the proposed transferee is financially
responsible.  Notwithstanding Landlord's agreement to act reasonably under
Section 16(A). above, Landlord may, within ten (10) days after its receipt of
all information and documentation required herein, either, (1) consent to or
reasonably refuse to consent to such Transfer in writing; or (2) subject to
first obtaining Tenant's approval thereto, cancel and terminate this Lease, in
whole or in part as appropriate, upon thirty (30) days' notice and recapture of
the space proposed for such subletting or assignment.  If Landlord fails to
respond within such 10-day period, Tenant may send a second written notice
requesting Landlord's consent, and if Landlord fails to respond within five (5)
business days after its receipt of such second notice, Landlord shall be deemed
to have approved such assignment or subletting.  In the event Landlord consents
to any such Transfer, the Transfer and consent thereto shall be in a form
approved by Landlord, and Tenant shall bear all costs and expenses incurred by
Landlord in connection with the review 

                                     -34-
<PAGE>
 
and approval of such documentation, which costs and expenses shall be deemed to
be at least Two Hundred Fifty Dollars ($250.00), and not to exceed One Thousand
Five Hundred Dollars ($1,500.00).

          D.  Tenant hereby covenants and agrees to pay to Landlord one half (
1/2) of all rent and other consideration which it receives which is in excess of
the Rent payable hereunder, after deduction of Tenant's reasonable costs of
subletting or assignment, within ten (10) days following receipt thereof by
Tenant.  In addition to any other rights Landlord may have, Landlord shall,
after Default by Tenant, have the right to contact any transferee and require
that all payments made pursuant to the Transfer shall be made directly to
Landlord.

          E.  If Tenant is a corporation, limited liability company or similar
entity, and if at any time during the Lease Term the entity or entities who own
the voting shares at the time of the execution of this Lease cease for any
reason (including but not limited to merger, consolidation or other
reorganization involving another corporation) to own a majority of such shares,
or if Tenant is a partnership and if at any time during the Lease Term the
general partner or partners who own the general partnership interests in the
partnership at the time of the execution of this Lease, cease for any reason to
own a majority of such interests (except as the result of transfers by gift,
bequest or inheritance to or for the benefit of members of the immediate family
of such original shareholder[s] or partner[s]), such an event shall be deemed to
be a Transfer.  The preceding sentence shall not apply whenever Tenant is a
corporation, the outstanding stock of which is listed on a recognized security
exchange, or if at least eighty percent (80%) of its voting stock is owned by
another corporation, the voting stock of which is so listed.

          F.  Notwithstanding anything herein to the contrary, Landlord hereby
consents to an assignment of this Lease, or a subletting of all or part of the
Premises, to (i) the parent of Tenant or to a wholly owned subsidiary of Tenant
or of such parent, (ii) any corporation in whom or with which Tenant may be
merged or consolidated, or (iii) any entity to whom Tenant sells all or
substantially all of its assets, provided that in each such instance such entity
expressly assumes all of Tenant's obligations hereunder and has a net worth at
least equal to the greater of (A) the net worth of Tenant on the date hereof or
(B) the net worth of Tenant immediately prior to such assignment or transaction.
With respect to the transactions described in Subsections (i) and (ii) above,
such net worth may be on a consolidated basis with Tenant's affiliated entity.
An initial public offering of Tenant's stock and any subsequent transfers shall
not be considered a Transfer hereunder.

                                     -35-
<PAGE>
 
          G.  Any Transfer consented to by Landlord in accordance with this
Article 16 shall be only for the Permitted Use and for no other purpose.  In no
event shall any Transfer release or relieve Tenant from any obligations under
this Lease.

                              ARTICLE 17:  LIENS

     Tenant will not permit any mechanic's liens or other liens to be placed
upon the Premises or Tenant's leasehold interest therein, the Building, or the
Property.  Landlord's title to the Building and Property is and always shall be
paramount to the interest of Tenant, and nothing herein contained shall empower
Tenant to do any act that can, shall or may encumber Landlord's title.  In the
event any such lien does attach, Tenant shall, within ten (10) days of notice of
the filing of said lien, either discharge or bond over such lien to the
satisfaction of Landlord and Landlord's Mortgagee (as hereinafter defined), and
in such a manner as to remove the lien as an encumbrance against the Building
and Property.  If Tenant shall fail to so discharge or bond over such lien,
then, in addition to any other right or remedy of Landlord, Landlord may, but
shall not be obligated to bond over or discharge the same.  Any amount paid by
Landlord for any of the aforesaid purposes, including reasonable attorneys' fees
(if and to the extent permitted by law) shall be paid by Tenant to Landlord on
demand as Additional Base Rental. Landlord shall have the right to post and keep
posted on the Premises any notices that may be provided by law or which Landlord
may deem to be proper for the protection of Landlord, the Premises and the
Building from such liens.

                  ARTICLE 18:  INDEMNITY AND WAIVER OF CLAIMS

          A.  Tenant shall indemnify, defend and hold Landlord, its members,
principals, beneficiaries, partners, officers, directors, employees,
Mortgagee(s) and agents, and the respective principals and members of any such
agents (collectively the "Landlord Related Parties") harmless against and from
all liabilities, obligations, damages, penalties, claims, costs, charges and
expenses, including, without limitation, reasonable attorneys' fees and other
professional fees (if and to the extent permitted by law), which may be imposed
upon, incurred by, or asserted against Landlord or any of the Landlord Related
Parties and arising, directly or indirectly, out of or in connection with the
use, occupancy or maintenance of the Premises by, through or under Tenant
including, without limitation, any of the following:  (1) any work or thing done
in, on or about the Premises or any part thereof by Tenant or any of its
transferees, agents, servants, contractors, employees, customers, licensees or
invitees; (2) any use, non-use, possession, occupation, condition, operation or
maintenance of the Premises or any part thereof; (3) any act or omission of
Tenant or any of its transferees, agents, servants, contractors, employees,
customers, licensees or invitees, 

                                     -36-
<PAGE>
 
regardless of whether such act or omission occurred within the Premises; (4) any
injury or damage to any person or property occurring in, on or about the
Premises or any part thereof; or (5) any failure on the part of Tenant to
perform or comply with any of the covenants, agreements, terms or conditions
contained in this Lease with which Tenant must comply or perform. In case any
action or proceeding is brought against Landlord or any of the Landlord Related
Parties by reason of any of the foregoing, Tenant shall, at Tenant's sole cost
and expense, resist and defend such action or proceeding with counsel approved
by Landlord or, at Landlord's option, reimburse Landlord for the cost of any
counsel retained directly by Landlord to defend and resist such action or
proceeding.

          B.  Landlord and the Landlord Related Parties shall not be liable for,
and Tenant hereby waives, all claims for loss or damage to Tenant's business or
damage to person or property sustained by Tenant or any person claiming by,
through or under Tenant [including Tenant's principals, agents and employees
(collectively, the "Tenant Related Parties")] resulting from any accident or
occurrence in, on or about the Premises, the Building or the Property,
including, without limitation, claims for loss, theft or damage resulting from:
(1) the Premises, Building, or Property, or any equipment or appurtenances
becoming out of repair; (2) wind or weather; (3) any defect in or failure to
operate, for whatever reason, any sprinkler, heating or air-conditioning
equipment, electric wiring, gas, water or steam pipes; (4) broken glass; (5) the
backing up of any sewer pipe or downspout; (6) the bursting, leaking or running
of any tank, water closet, drain or other pipe; (7) the escape of steam or
water; (8) water, snow or ice being upon or coming through the roof, skylight,
stairs, doorways, windows, walks or any other place upon or near the Building;
(9) the falling of any fixture, plaster, tile or other material; (10) any act,
omission or negligence of other tenants, licensees or any other persons or
occupants of the Building or of adjoining or contiguous buildings, or owners of
adjacent or contiguous property or the public, or by construction of any
private, public or quasi-public work; or (11) any other cause of any nature
except, as to items 19, where such loss or damage is due to Landlord's
negligence or willful misconduct, or due to Landlord's willful failure to make
repairs required to be made pursuant to other provisions of this Lease, after
the expiration of a reasonable time after written notice to Landlord of the need
for such repairs.  To the maximum extent permitted by law, Tenant agrees to use
and occupy the Premises, and to use such other portions of the Building as
Tenant is herein given the right to use, at Tenant's own risk.

          C.  Landlord shall indemnify, defend and hold Tenant harmless from and
against all liabilities, damages, losses, claims, and expenses, including
reasonable attorneys' fees arising from any negligent act of Landlord or its
officers, contractors, licensees, agents, employees, clients, or customers in or
about the Building or 

                                     -37-
<PAGE>
 
Premises, or arising from any breach or default under this Lease by Landlord.
Landlord shall not be liable for any act or neglect of Tenant or any other
tenant or occupant of the Building or any third parties. In no event shall
Landlord be liable to Tenant for any damage to the Premises or for any loss,
damage or injury to any property therein or thereon occasioned by bursting,
rupture, leakage or overflow of any plumbing or other pipes (including, without
limitation, water, steam and/or refrigerant lines), sprinklers, tanks, drains,
drinking fountains or washstands or other similar cause in, above, upon or about
the Premises or the Building, unless due to the negligence or willful misconduct
of Landlord or its officers, contractors, licensees, agents, employees, clients
or customers.

                        ARTICLE 19:  TENANT'S INSURANCE

          A.  At all times commencing on and after the earlier of the
Commencement Date and the date Tenant or its agents, employees or contractors
enters the Premises for any purpose, Tenant shall carry and maintain, at its
sole cost and expense:

              1.  Commercial General Liability Insurance applicable to the
Premises and its appurtenances providing, on an occurrence basis, a minimum
combined single limit of Two Million Dollars ($2,000,000.00), with a contractual
liability endorsement covering those of Tenant's indemnity obligations under
this Lease customarily covered by such policies.

              2.  All Risks of Physical Loss Insurance written at replacement
cost value and with a replacement cost endorsement covering all of Tenant's
Property in the Premises.

              3.  Workers' Compensation Insurance as required by the state of
Washington and in amounts as may be required by applicable statute, and
Employers' Liability Coverage of One Million Dollars ($1,000,000.00) per
occurrence.

          B.  Except for items for which Landlord is responsible under Exhibit
D, the Work Letter Agreement, before any repairs, alterations, additions,
improvements, or construction are undertaken by or on behalf of Tenant, Tenant
shall carry and maintain, at its expense, or Tenant shall require any contractor
performing work on the Premises to carry and maintain, at no expense to
Landlord, in addition to Workers' Compensation Insurance as required by the
jurisdiction in which the Building is located, All Risk Builder's Risk Insurance
in the amount of the replacement cost of any alterations, additions or
improvements (or such other amount reasonably required by Landlord) and
Commercial General Liability Insurance 

                                     -38-
<PAGE>
 
(including, without limitation, Contractor's Liability coverage, Contractual
Liability coverage and Completed Operations coverage,) written on an occurrence
basis with a minimum combined single limit of Two Million Dollars
($2,000,000.00) and adding "the named Landlord hereunder (or any successor
thereto) and its respective members, principals, beneficiaries, partners,
officers, directors, employees, agents and any Mortgagee(s)", and other
designees of Landlord as the interest of such designees shall appear, as
additional insureds (collectively referred to as the "Additional Insureds").

          C.  Any company writing any insurance which Tenant is required to
maintain or cause to be maintained pursuant to the terms of this Lease (all such
insurance as well as any other insurance pertaining to the Premises or the
operation of Tenant's business therein being referred to as "Tenant's
Insurance"), as well as the form of such insurance, shall at all times be
subject to Landlord's reasonable approval, and each such insurance company shall
have an A.M. Best rating of "A-" or better and shall be licensed and qualified
to do business in the state in which the Premises is located.  All policies
evidencing Tenant's Insurance (except for Workers' Compensation Insurance) shall
specify Tenant as named insured and the Additional Insureds as additional
insureds.  Provided that the coverage afforded Landlord and any designees of
Landlord shall not be reduced or otherwise adversely affected, all of Tenant's
Insurance may be carried under a blanket policy covering the Premises and any
other of Tenant's locations.  All policies of Tenant's Insurance shall contain
endorsements that the insurer(s) will give to Landlord and its designees at
least thirty (30) days' advance written notice of any cancellation, termination
or lapse of said insurance.  Tenant shall be solely responsible for payment of
premiums for all of Tenant's Insurance.  Tenant shall deliver to Landlord at
least fifteen (15) days prior to the time Tenant's Insurance is first required
to be carried by Tenant, and upon renewals at least fifteen (15) days prior to
the expiration of any such insurance coverage, a certificate of insurance of all
policies procured by Tenant in compliance with its obligations under this Lease.
The limits of Tenant's Insurance shall in no event limit Tenant's liability
under this Lease.

          D.  Tenant shall not do or fail to do anything in, upon or about the
Premises which will:  (1) violate the terms of any of Landlord's insurance
policies; (2) prevent Landlord from obtaining policies of insurance acceptable
to Landlord or any Mortgagees; or (3) result in an increase in the rate of any
insurance on the Premises, the Building, any other property of Landlord or of
others within the Building.  In the event of the occurrence of any of the events
set forth in this Section, Tenant shall pay Landlord upon demand, as Additional
Base Rental, the cost of the amount of any increase in any such insurance
premium, provided that the acceptance by Landlord of such payment shall not be
construed to be a waiver of any rights by Landlord in connection with a default
by Tenant under the Lease.  If Tenant fails to 

                                     -39-
<PAGE>
 
obtain the insurance coverage required by this Lease, Landlord may, at its
option, obtain such insurance for Tenant, and Tenant shall pay, as Additional
Base Rental, the cost of all premiums thereon and all of Landlord's costs
associated therewith.

                           ARTICLE 20:  SUBROGATION

     Notwithstanding anything set forth in this Lease to the contrary, Landlord
and Tenant do hereby waive any and all right of recovery, claim, action or cause
of action against the other, their respective principals, beneficiaries,
partners, officers, directors, agents, and employees, for any loss or damage
that may occur to Landlord or Tenant or any party claiming by, through or under
Landlord or Tenant, as the case may be, with respect to their respective
property, the Building, the Property or the Premises or any addition or
improvements thereto, or any contents therein, by reason of fire, the elements
or any other cause, regardless of cause or origin, including the negligence of
Landlord or Tenant, or their respective principals, beneficiaries, partners,
officers, directors, agents and employees, which loss or damage is (or would
have been, had the insurance required by this Lease been carried) covered by
insurance.  Since this mutual waiver will preclude the assignment of any such
claim by subrogation (or otherwise) to an insurance company (or any other
person), Landlord and Tenant each agree to give each insurance company which has
issued, or in the future may issue, policies of insurance, with respect to the
items covered by this waiver, written notice of the terms of this mutual waiver,
and to have such insurance policies properly endorsed, if necessary, to prevent
the invalidation of any of the coverage provided by such insurance policies by
reason of such mutual waiver.  For the purpose of the foregoing waiver, the
amount of any deductible applicable to any loss or damage shall be deemed
covered by, and recoverable by the insured under the insurance policy to which
such deductible relates. In the event that Tenant is permitted to and self-
insures any risk which would have been covered by the insurance required to be
carried by Tenant pursuant to Article 19 of the Lease, or if Tenant fails to
carry any insurance required to be carried by Tenant pursuant to Article 19 of
this Lease, then all loss or damage to Tenant, its leasehold interest, its
business, its property, the Premises or any additions or improvements thereto or
contents thereof shall be deemed covered by and recoverable by Tenant under
valid and collectible policies of insurance.

                       ARTICLE 21:  LANDLORD'S INSURANCE

     Landlord shall procure and maintain commercial general liability insurance
with broad form general liability endorsement covering all claims with respect
to injuries or damages to persons or property sustained in, on or about the
Building and the appurtenances thereto, including the sidewalks and alleyways
adjacent thereto, with limits of liability no less than five million dollars
($5,000,000) combined single 

                                     -40-
<PAGE>
 
limit per occurrence and in the aggregate. Such limits may be achieved through
the use of umbrella liability insurance otherwise meeting the requirements of
this Article 21.

     Landlord will procure and maintain physical damage insurance covering all
real and personal property, excluding property paid for by tenants and not
reimbursed by Landlord or paid for by Landlord for which tenants have reimbursed
Landlord, (but including the Tenant Improvements to the extent paid for by the
Allowance) located on or in, or constituting a part of, the Building in an
amount equal to at least ninety percent (90%) of replacement value of all such
property with a coinsurance waiver.  Such insurance shall afford coverage for
damages resulting from (i) perils covered by what is commonly referred to as
"all risk" coverage insurance (but excluding earthquake and flood if, in light
of the costs and deductibles applicable to such coverage in the then current
insurance market, the exclusion of such perils would be considered reasonable),
and (ii) boilers and machinery coverage as appropriate for apparatus located in
the Building.

                         ARTICLE 22:  CASUALTY DAMAGE

     If the Premises or any part thereof shall be damaged by fire or other
casualty, Tenant shall give prompt written notice thereof to Landlord.  In case
the Building shall be so damaged that in Landlord's reasonable judgment,
substantial alteration or reconstruction of the Building shall be required
(whether or not the Premises has been damaged by such casualty) or in the event
Landlord will not be permitted by applicable law to rebuild the Building in
substantially the same form and area as existed prior to the fire or casualty or
in the event the Premises has been materially damaged and there is less than two
(2) years of the Lease Term remaining on the date of such casualty or in the
event any Mortgagee should require that the insurance proceeds in excess of
$250,000 payable as a result of a casualty be applied to the payment of the
mortgage debt or in the event of any material uninsured loss to the Building
(meaning an uninsured loss of $250,000 or more, unless Tenant pays for any
uninsured loss in excess of that amount), Landlord may, at its option, terminate
this Lease by notifying Tenant in writing of such termination within ninety (90)
days after the date of such casualty, provided such election to terminate must
be made in good faith and not merely as a means to re-lease the Premises at
rates more favorable than those set forth in this Lease.  Such termination shall
be effective as of the date of fire or casualty, with respect to any portion of
the Premises that was rendered untenantable, and the effective date of
termination specified in Landlord's notice, with respect to any portion of the
Premises that remained tenantable.  If Landlord does not elect to terminate this
Lease, Landlord shall commence and proceed with reasonable diligence to restore
the Building (provided that Landlord shall not be required to 

                                     -41-
<PAGE>
 
restore any unleased premises in the Building) and the Tenant Improvements (but
excluding any improvements, alterations or additions made by Tenant in violation
of this Lease) located within the Premises, if any, which Landlord has insured
to substantially the same condition they were in immediately prior to the
happening of the casualty. Notwithstanding the foregoing, Landlord's obligation
to restore the Building, and the Tenant Improvements, if any, shall not require
Landlord to expend for such repair and restoration work more than the insurance
proceeds actually received by the Landlord as a result of the casualty. Tenant
shall have the right to terminate this Lease if (i) any such restoration of the
Premises is not completed within 180 days after the date of such casualty and
such delays prevent Tenant from occupying the Premises for Tenant's normal
business operations; or (ii) the Premises are damaged within the last two (2)
years of the Lease Term and such damage prevents Tenant from occupying the
Premises for Tenant's normal business operations. When repairs to the Premises
have been completed by Landlord, Tenant shall complete the restoration or
replacement of all Tenant's Property necessary to permit Tenant's reoccupancy of
the Premises, and Tenant shall present Landlord with evidence satisfactory to
Landlord of Tenant's ability to pay such costs prior to Landlord's commencement
of repair and restoration of the Premises. Landlord shall not be liable for any
inconvenience or annoyance to Tenant or injury to the business of Tenant
resulting in any way from such damage or the repair thereof, except that,
subject to the provisions of the next sentence, Landlord shall allow Tenant a
fair diminution of Rent on a per diem basis during the time and to the extent
any damage to the Premises causes the Premises to be rendered untenantable and
not used by Tenant. If the Premises or any other portion of the Building is
damaged by fire or other casualty resulting from the negligence of Tenant or any
Tenant Related Parties, the Rent hereunder shall not be diminished during any
period during which the Premises, or any portion thereof, is untenantable
(except to the extent Landlord is entitled to be reimbursed by the proceeds of
any rental interruption insurance), and Tenant shall be liable to Landlord for
the cost of the repair and restoration of the Building caused thereby to the
extent such cost and expense is not covered by insurance proceeds. Landlord and
Tenant hereby waive the provisions of any law from time to time in effect during
the Lease Term relating to the effect upon leases of partial or total
destruction of leased property. Landlord and Tenant agree that their respective
rights in the event of any damage to or destruction of the Premises shall be
those specifically set forth herein.

                      ARTICLE 23:  INTENTIONALLY DELETED

                                     -42-
<PAGE>
 
                           ARTICLE 24:  CONDEMNATION

     If (a) the whole or any substantial part of the Premises or (b) any portion
of the Building or Property which would leave the remainder of the Building
unsuitable for use as an office building comparable to its use on the
Commencement Date, shall be taken or condemned for any public or quasi-public
use under governmental law, ordinance or regulation, or by right of eminent
domain, or by private purchase in lieu thereof, then Landlord may, at its
option, terminate this Lease effective as of the date the physical taking of
said Premises or said portion of the Building or Property shall occur.  If any
taking or condemnation materially impairs Tenant's ability to use the Premises
for Tenant's uses, Tenant may elect to terminate this Lease effective as of the
date of such taking by delivering written notice to Landlord.  In the event this
Lease is not terminated, the Rentable Area of the Building, the Rentable Area of
the Premises and Tenant's Pro Rata Share shall be appropriately adjusted.  In
addition, Rent for any portion of the Premises so taken or condemned shall be
abated during the unexpired term of this Lease effective when the physical
taking of said portion of the Premises shall occur.  All compensation awarded
for any such taking or condemnation, or sale proceeds in lieu thereof, shall be
the property of Landlord, and Tenant shall have no claim thereto, the same being
hereby expressly waived by Tenant, except for any portions of such award or
proceeds which are specifically allocated by the condemning or purchasing party
for the taking of or damage to trade fixtures of Tenant, which Tenant
specifically reserves to itself.

                        ARTICLE 25:  EVENTS OF DEFAULT

     The following events shall be deemed to be events of default under this
Lease:

          A.  Tenant shall fail to pay when due any Base Rental, Additional Base
Rental or other Rent under this Lease and such failure shall continue for three
(3) business days after receipt of written notice from Landlord (hereinafter
sometimes referred to as a "Monetary Default").

          B.  Any failure by Tenant (other than a Monetary Default) to comply
with any term, provision or covenant of this Lease, including, without
limitation, the rules and regulations, which failure is not cured within thirty
(30) days after receipt of notice of the occurrence of such failure, provided
that if any such failure creates a hazardous condition, such failure must be
cured immediately, and further provided, however, that with respect to any such
non-hazardous default capable of being cured by Tenant which cannot be cured
within thirty (30) days, the default shall not be deemed to be uncured if Tenant
commences to cure within thirty (30) days and for so long as Tenant is
diligently pursuing the cure thereof.

                                     -43-
<PAGE>
 
          C.  Tenant shall become insolvent, or shall make a transfer in fraud
of creditors, or shall commit an act of bankruptcy or shall make an assignment
for the benefit of creditors, or Tenant shall admit in writing its inability to
pay its debts as they become due.

          D.  Tenant shall file a petition under any section or chapter of the
United States Bankruptcy Code, as amended, pertaining to bankruptcy, or under
any similar law or statute of the United States or any State thereof, or Tenant
shall be adjudged bankrupt or insolvent in proceedings filed against Tenant
thereunder; or a petition or answer proposing the adjudication of Tenant as a
debtor or its reorganization under any present or future federal or state
bankruptcy or similar law shall be filed in any court and such petition or
answer shall not be discharged or denied within sixty (60) days after the filing
thereof.

          E.  A receiver or trustee shall be appointed for all or substantially
all of the assets of Tenant or of the Premises or of any of Tenant's Property
located thereon in any proceeding brought by Tenant, or any such receiver or
trustee shall be appointed in any proceeding brought against Tenant and shall
not be discharged within sixty (60) days after such appointment or Tenant shall
consent to or acquiesce in such appointment.

          F.  The leasehold estate hereunder shall be taken on execution or
other process of law or equity in any action against Tenant.

          G.  The liquidation, termination, dissolution, forfeiture of right to
do business, or death of Tenant.

                             ARTICLE 26:  REMEDIES

          A.  Upon the occurrence of any event or events of default under this
Lease, Landlord shall have the option to pursue any one or more of the following
remedies without any notice (except as expressly prescribed in Article 25 above)
or demand whatsoever (and without limiting the generality of the foregoing,
Tenant hereby specifically waives notice and demand for payment of Rent or other
obligations due [except as expressly prescribed in Article 25 above] and waives
any and all other notices or demand requirements imposed by applicable law):

              1.  Terminate this Lease, in which event Tenant shall immediately
surrender the Premises to Landlord.  If Tenant fails to surrender the Premises
upon termination of the Lease hereunder, Landlord may without prejudice to any
other remedy which it may have, enter upon and take possession of the Premises
and expel or remove Tenant and any other person who may be occupying said

                                     -44-
<PAGE>
 
Premises, or any part thereof, and Tenant hereby agrees to pay to Landlord on
demand the amount of all loss and damage, including consequential damage, which
Landlord may suffer by reason of such termination, whether through inability to
relet the Premises on satisfactory terms or otherwise, specifically including
but not limited to all Costs of Reletting (hereinafter defined) and any
deficiency that may arise by reason of any reletting or failure to relet.

              2.  Enter upon and take possession of the Premises and expel or
remove Tenant or any other person who may be occupying said Premises, or any
part thereof, without having any civil or criminal liability therefor and
without terminating this Lease. Landlord may (but shall be under no obligation
to) relet the Premises or any part thereof for the account of Tenant, in the
name of Tenant or Landlord or otherwise, without notice to Tenant for such term
or terms which may be greater or less than the period which would otherwise have
constituted the balance of the Lease Term and on such conditions (which may
include concessions, free rent and alterations of the Premises) and for such
uses as Landlord in its absolute discretion may determine, and Landlord may
collect and receive any rents payable by reason of such reletting. Tenant agrees
to pay Landlord on demand all reasonable Costs of Reletting and any deficiency
that may arise by reason of such reletting or failure to relet. Landlord shall
not be responsible or liable for any failure to relet the Premises or any part
thereof or for any failure to collect any Rent due upon any such reletting. No
such re-entry or taking of possession of the Premises by Landlord shall be
construed as an election on Landlord's part to terminate this Lease unless a
written notice of such termination is given to Tenant.

              3.  Enter upon the Premises without having any civil or criminal
liability therefor, and do whatever Tenant is obligated to do under the terms of
this Lease, and Tenant agrees to reimburse Landlord on demand for any reasonable
expense which Landlord may incur in thus affecting compliance with Tenant's
obligations under this Lease together with interest at the lesser of a per annum
rate equal to:  (a) the Maximum Rate, or (b) the Prime Rate plus five percent
(5%).

              4.  In order to regain possession of the Premises and to deny
Tenant access thereto in any instance in which Landlord has terminated this
Lease or Tenant's right to possession, or to limit access to the Premises in
accordance with local law in the event of a default by Tenant, Landlord or its
agent may, at the expense and liability of the Tenant, alter or change any or
all locks or other security devices controlling access to the Premises without
posting or giving notice of any kind to Tenant. Landlord shall have no
obligation to provide Tenant a key or grant Tenant access to the Premises so
long as Tenant is in default under this Lease. Tenant shall not be entitled to
recover possession of the Premises, terminate this Lease, or recover 

                                     -45-
<PAGE>
 
any actual, incidental, consequential, punitive, statutory or other damages or
award of attorneys' fees, by reason of Landlord's alteration or change of any
lock or other security device. Landlord may, without notice, remove and either
dispose of or store, at Tenant's expense, any property belonging to Tenant that
remains in the Premises after Landlord has regained possession thereof.

              5.  Terminate this Lease, in which event, Tenant shall immediately
surrender the Premises to Landlord and pay to Landlord the sum of:  (a) all Rent
accrued hereunder through the date of termination, and, upon Landlord's
determination thereof, (b) an amount equal to: the total Rent that Tenant would
have been required to pay for the remainder of the Lease Term discounted to
present value at the Prime Rate then in effect, minus the then present fair
rental value of the Premises for the remainder of the Lease Term, similarly
discounted, after deducting all anticipated Costs of Reletting (as defined
below).

          B.  For purposes of this Lease, the term "Costs of Reletting" shall
mean all reasonable costs and expenses incurred by Landlord in connection with
the reletting of the Premises, including without limitation, the cost of
cleaning, renovation, repairs, decoration and alteration of the Premises for a
new tenant or tenants, advertisement, marketing, brokerage and legal fees (if
and to the extent permitted by law), the cost of protecting or caring for the
Premises while vacant, the cost of removing and storing any property located on
the Premises, any increase in insurance premiums caused by the vacancy of the
Premises and any other out-of-pocket expenses reasonably incurred by Landlord
including tenant incentives, allowances and inducements.

          C.  Except as otherwise herein provided, no repossession or re-
entering of the Premises or any part thereof pursuant to Article 26 hereof or
otherwise shall relieve Tenant of its liabilities and obligations hereunder, all
of which shall survive such repossession or re-entering.  Notwithstanding any
such repossession or re-entering by reason of the occurrence of an event of
default, Tenant will pay to Landlord the Rent required to be paid by Tenant
pursuant to this Lease.

          D.  No right or remedy herein conferred upon or reserved to Landlord
is intended to be exclusive of any other right or remedy, and each and every
right and remedy shall be cumulative and in addition to any other right or
remedy given hereunder or now or hereafter existing by agreement, applicable law
or in equity.  In addition to other remedies provided in this Lease, Landlord
shall be entitled, to the extent permitted by applicable law, to injunctive
relief, or to a decree compelling performance of any of the covenants,
agreements, conditions or provisions of this Lease, or to any other remedy
allowed to Landlord at law or in equity.  Forbearance by Landlord to enforce one
or more of the remedies herein provided 

                                     -46-
<PAGE>
 
upon an event of default shall not be deemed or construed to constitute a waiver
of such default.

          E.  This Article 26 shall be enforceable to the maximum extent such
enforcement is not prohibited by applicable law, and the unenforceability of any
portion thereof shall not thereby render unenforceable any other portion.

                ARTICLE 27:  LIMITATION OF LIABILITY; GUARANTY

          A.  NOTWITHSTANDING ANYTHING TO THE CONTRARY CONTAINED IN THIS LEASE,
THE LIABILITY OF LANDLORD (AND OF ANY SUCCESSOR LANDLORD HEREUNDER) TO TENANT
SHALL BE LIMITED TO THE INTEREST OF LANDLORD IN THE BUILDING AND ANY PROCEEDS
THEREOF, AND TENANT AGREES TO LOOK SOLELY TO LANDLORD'S INTEREST IN THE BUILDING
AND THE PROCEEDS THEREOF FOR THE RECOVERY OF ANY JUDGMENT OR AWARD AGAINST THE
LANDLORD, IT BEING INTENDED THAT NEITHER LANDLORD NOR ANY MEMBER, PRINCIPAL,
PARTNER, SHAREHOLDER, OFFICER, DIRECTOR OR BENEFICIARY OF LANDLORD SHALL BE
PERSONALLY LIABLE FOR ANY JUDGMENT OR DEFICIENCY.  TENANT HEREBY COVENANTS THAT,
PRIOR TO THE FILING OF ANY SUIT FOR AN ALLEGED DEFAULT BY LANDLORD HEREUNDER, IT
SHALL GIVE LANDLORD AND ALL MORTGAGEES WHOM TENANT HAS BEEN NOTIFIED HOLD
MORTGAGES OR DEED OF TRUST LIENS ON THE PROPERTY, BUILDING OR PREMISES NOTICE
AND REASONABLE TIME TO CURE SUCH ALLEGED DEFAULT BY LANDLORD.  IN ADDITION,
TENANT ACKNOWLEDGES THAT ANY ENTITY MANAGING THE BUILDING ON BEHALF OF LANDLORD,
OR WHICH EXECUTES THIS LEASE AS AGENT FOR LANDLORD, IS ACTING SOLELY IN ITS
CAPACITY AS AGENT FOR LANDLORD AND SHALL NOT BE LIABLE FOR ANY OBLIGATIONS,
LIABILITIES, LOSSES OR DAMAGES ARISING OUT OF OR IN CONNECTION WITH THIS LEASE,
ALL OF WHICH ARE EXPRESSLY WAIVED BY TENANT.

          B.  Notwithstanding anything to the contrary contained in this Section
27 or elsewhere in this Lease, the obligations of Landlord to complete
Landlord's Work and the Initial Tenant Improvements, as provided in Article 3,
and cause the Commencement Date to occur, subject to all other terms and
conditions of this Lease, are hereby guaranteed by Wright Runstad Associates
Limited Partnership, a Washington limited partnership ("Guarantor"), and upon
any transfer described in Section 38.E the obligations of Guarantor shall
continue unmodified and in full force and effect, and the Guarantor shall not be
relieved of any such liabilities or obligations by reason of such transfer.
Upon fulfillment of the above-described 

                                     -47-
<PAGE>
 
obligations and expiration of the warranty period in Article 3 above,
Guarantor's obligations hereunder shall terminate.

                            ARTICLE 28:  NO WAIVER

     Failure of Landlord to declare any default immediately upon its occurrence,
or delay in taking any action in connection with an event of default shall not
constitute a waiver of such default, nor shall it constitute an estoppel against
Landlord, but Landlord shall have the right to declare the default at any time
and take such action as is lawful or authorized under this Lease.  Failure by
Landlord to enforce its rights with respect to any one default shall not
constitute a waiver of its rights with respect to any subsequent default.
Receipt by Landlord of Tenant's keys to the Premises shall not constitute an
acceptance or surrender of the Premises.

                       ARTICLE 29:  EVENT OF BANKRUPTCY

     In addition to, and in no way limiting the other remedies set forth herein,
Landlord and Tenant agree that if Tenant ever becomes the subject of a voluntary
or involuntary bankruptcy, reorganization, composition, or other similar type
proceeding under the federal bankruptcy laws, as now enacted or hereinafter
amended, then, to the extent permitted by law:

          A.  "Adequate protection" of Landlord's interest in the Premises
pursuant to the provisions of Section 361 and 363 (or their successor sections)
of the Bankruptcy Code, 11 U.S.C. Section 101 et seq., (such Bankruptcy Code as
amended from time to time being herein referred to as the "Bankruptcy Code"),
prior to assumption and/or assignment of the Lease by Tenant shall include, but
not be limited to all (or any part) of the following:

              1.  the continued payment by Tenant of the Base Rental and all
other Rent due and owing hereunder and the performance of all other covenants
and obligations hereunder by Tenant;

              2.  the furnishing of an additional/new security deposit by Tenant
in the amount of three (3) times the then current monthly Base Rental.

          B.  "Adequate assurance of future performance" by Tenant and/or any
assignee of Tenant pursuant to Bankruptcy Code Section 365 will include (but not
be limited to) payment of an additional/new Security Deposit in the amount of
three (3) times the then current monthly Base Rental payable hereunder.

          C.  Any person or entity to which this Lease is assigned pursuant to
the provisions of the Bankruptcy Code, shall be deemed without further act or
deed to 

                                     -48-
<PAGE>
 
have assumed all of the obligations of Tenant arising under this Lease on and
after the effective date of such assignment. Any such assignee shall, upon
demand by Landlord, execute and deliver to Landlord an instrument confirming
such assumption of liability.

          D.  Notwithstanding anything in this Lease to the contrary, all
amounts payable by Tenant to or on behalf of the Landlord under this Lease,
whether or not expressly denominated as "Rent," shall constitute "rent" for the
purposes of Section 502(b)(6) of the Bankruptcy Code.

          E.  If this Lease is assigned to any person or entity pursuant to the
provisions of the Bankruptcy Code, any and all monies or other considerations
payable or otherwise to be delivered to Landlord (including Base Rentals and
other Rent hereunder), shall be and remain the exclusive property of Landlord
and shall not constitute property of Tenant or of the bankruptcy estate of
Tenant.  Any and all monies or other considerations constituting Landlord's
property under the preceding sentence not paid or delivered to Landlord shall be
held in trust by Tenant or Tenant's bankruptcy estate for the benefit of
Landlord and shall be promptly paid to or turned over to Landlord.

          F.  If Tenant assumes this Lease and proposes to assign the same
pursuant to the provisions of the Bankruptcy Code to any person or entity who
shall have made a bona fide offer to accept an assignment of this Lease on terms
acceptable to the Tenant, then notice of such proposed offer/assignment, setting
forth:  (1) the name and address of such person or entity, (2) all of the terms
and conditions of such offer, and (3) the adequate assurance to be provided
Landlord to assure such person's or entity's future performance under the Lease,
shall be given to Landlord by Tenant no later than twenty (20) days after
receipt by Tenant, but in any event no later than ten (10) days prior to the
date that Tenant shall make application to a court of competent jurisdiction for
authority and approval to enter into such assumption and assignment, and
Landlord shall thereupon have the prior right and option, to be exercised by
notice to Tenant given at any time prior to the effective date of such proposed
assignment, to accept an assignment of this Lease upon the same terms and
conditions and for the same consideration, if any, as the bona fide offer made
by such persons or entity, less any brokerage commission which may be payable
out of the consideration to be paid by such person for the assignment of this
Lease.

          G.  To the extent permitted by law, Landlord and Tenant agree that
this Lease is a contract under which applicable law excuses Landlord from
accepting performance from (or rendering performance to) any person or entity
other than Tenant within the meaning of Sections 365(c) and 365(e)(2) of the
Bankruptcy Code.

                       ARTICLE 30:  WAIVER OF JURY TRIAL

     Landlord and Tenant hereby waive any right to a trial by jury in any action
or proceeding based upon, or related to, the subject matter of this Lease.  This
waiver is knowingly, intentionally, and voluntarily made by Tenant, and Tenant
acknowledges that neither Landlord nor any person acting on behalf of Landlord
has made any representations of fact to induce this waiver of trial by jury or
in any way to modify or nullify its effect.  Tenant further acknowledges that it
has been represented (or has had the opportunity to be represented) in the
signing of this Lease and in the making of this waiver by independent legal
counsel, selected of its own free will, and that it has had the opportunity to
discuss this waiver with counsel.

                           ARTICLE 31:  HOLDING OVER

     In the event of holding over by Tenant after expiration or other
termination of this Lease or in the event Tenant continues to occupy the
Premises after the termination of Tenant's right of possession pursuant to
Articles 25 and 26 hereof, occupancy of the Premises subsequent to such
termination or expiration shall be that of a tenancy at sufferance and in no
event for month-to-month or year-to-year.  Tenant shall, throughout the entire
holdover period, be subject to all the terms and provisions of this Lease and
shall pay for its use and occupancy an amount (on a per month basis without
reduction for any partial months during any such holdover) equal to 135% of the
sum of the Base Rental and Additional Base Rental due for the period immediately
preceding such holding over, provided that in no event shall Base Rental and
Additional Base Rental during the holdover period be less than the fair market
rental for the Premises.  No holding over by Tenant or payments of money by
Tenant to Landlord after the expiration of the term of this Lease shall be
construed to extend the Lease Term or prevent Landlord from recovery of
immediate possession of the Premises by summary proceedings or otherwise.  In
addition to the obligation to pay the amounts set forth above during any such
holdover period, Tenant also shall be liable to Landlord for all damage,
including any consequential damage, which Landlord may suffer by reason of any
holding over by Tenant, and Tenant shall indemnify Landlord against any and all
claims made by any other tenant or prospective tenant against Landlord for delay
by Landlord in delivering possession of the Premises to such other tenant or
prospective tenant.

         ARTICLE 32:  SUBORDINATION TO MORTGAGES; ESTOPPEL CERTIFICATE

     Tenant accepts this Lease subject and subordinate to any mortgage, deed of
trust, ground lease or other lien presently existing or hereafter arising upon
the Premises, or upon the Building and/or the Property and to any renewals,

                                     -50-
<PAGE>
 
modifications, refinancings and extensions thereof (any such mortgage, deed of
trust, lease or other lien being hereinafter referred to as a "Mortgage", and
the person or entity having the benefit of same being referred to hereinafter as
a "Mortgagee"), but Tenant agrees that any such Mortgagee shall have the right
at any time to subordinate such Mortgage to this Lease on such terms and subject
to such conditions as such Mortgagee may deem appropriate in its discretion.
This clause shall be self-operative and no further instrument of subordination
shall be required.  However, Landlord is hereby irrevocably vested with full
power and authority to subordinate this Lease to any Mortgage, and Tenant agrees
upon demand to execute such further instruments subordinating this Lease,
acknowledging the subordination of this Lease or attorning to the holder of any
such Mortgage as Landlord may request.  Notwithstanding the foregoing, any such
subordination by Tenant shall be conditioned upon Tenant's receipt from the
Mortgagee of a nondisturbance agreement on terms reasonably acceptable to
Tenant.  Landlord shall also use its commercially reasonably best efforts to
obtain a nondisturbance from any Mortgagee on the Property as of the date this
Lease is signed, if any.  In the event that Tenant should fail to execute any
subordination or other agreement required by this Article promptly as requested,
Tenant hereby irrevocably constitutes Landlord as its attorney-in-fact to
execute such instrument in Tenant's name, place and stead, it being agreed that
such power is one coupled with an interest in Landlord and is accordingly
irrevocable.  If any person shall succeed to all or part of Landlord's interests
in the Premises whether by purchase, foreclosure, deed in lieu of foreclosure,
power of sale, termination of lease or otherwise, and if and as so requested or
required by such successor-in-interest, Tenant shall, without charge, attorn to
such successor-in-interest.  Tenant agrees that it will from time to time upon
request by Landlord and, within five (5) days of the date of such request,
execute and deliver to such persons as Landlord shall request an estoppel
certificate or other similar statement in recordable form certifying that this
Lease is unmodified and in full force and effect (or if there have been
modifications, that the same is in full force and effect as so modified),
stating the dates to which Rent and other charges payable under this Lease have
been paid, stating that Landlord is not in default hereunder (or if Tenant
alleges a default stating the nature of such alleged default) and further
stating such other matters as Landlord shall reasonably require.

                         ARTICLE 33:  ATTORNEYS' FEES

     In the event that Landlord or Tenant should retain counsel and/or institute
any suit against the other for violation of or to enforce any of the covenants
or conditions of this Lease, or should either party institute any suit against
the other for violation of any of the covenants or conditions of this Lease, or
should either party intervene in any suit in which the other is a party to
enforce or protect its interest or rights 

                                     -51-
<PAGE>
 
hereunder, the prevailing party in any such suit shall be entitled to all of its
costs, expenses and reasonable fees of its attorney(s) (if and to the extent
permitted by law) in connection therewith.

                              ARTICLE 34:  NOTICE

     Whenever any demand, request, approval, consent or notice ("Notice") shall
or may be given to either of the parties by the other, each such Notice shall be
in writing and shall be sent by registered or certified mail with return receipt
requested, or sent by personal delivery or by overnight courier service (such as
Federal Express) at the respective addresses of the parties for notices as set
forth in Section 1(A)(11) of this Lease.  Any Notice under this Lease delivered
by registered or certified mail shall be deemed to have been given, delivered,
received and effective on the earlier of (a) the third business day following
the day on which the same shall have been mailed with sufficient postage prepaid
or (b) the delivery date indicated on the return receipt.  Notice sent by
overnight courier service shall be deemed given, delivered, received and
effective upon the business day after such notice is delivered to or picked up
by the overnight courier service, and notice by personal delivery shall be
deemed given on the day received.  Either party may, at any time, change its
Notice Address by giving the other party Notice stating the change and setting
forth the new address.

                         ARTICLE 35:  LANDLORD'S LIEN

     Landlord shall have all statutory lien rights for Rent

                         ARTICLE 36:  EXCEPTED RIGHTS

     This Lease does not grant any rights to light or air over or about the
Building, except as provided in Section 38(S).  Landlord specifically excepts
and reserves to itself the use of any roofs, the exterior portions of the
Premises, all rights to the land and improvements below the improved floor level
of the Premises, the improvements and air rights above the Premises and the
improvements and air rights located outside the demising walls of the Premises,
and such areas within the Premises as are required for installation of utility
lines and other installations required to serve any occupants of the Building
and the right to maintain and repair the same, and no rights with respect
thereto are conferred upon Tenant unless otherwise specifically provided herein.
Landlord further reserves to itself the right from time to time:  (a) to change
the Building's name; (b) to install, fix and maintain signs on the exterior and
interior of the Building; (c) to designate and approve window coverings; (d) to
make any decorations, alterations, additions, improvements to the Building, or
any part thereof (including the Premises) which Landlord shall desire, or deem
necessary for the safety, protection, preservation or improvement of the
Building, or as Landlord may 

                                     -52-
<PAGE>
 
be required to do by law, provided that Landlord shall use all reasonable
efforts to minimize interference with Tenant's business operations when
performing such functions; (e) to have access to the Premises to perform its
duties and obligations and to exercise its rights under this Lease; (f) to
retain at all times and to use pass-keys to all locks within and into the
Premises; (g) to approve the weight, size, or location of heavy equipment, or
articles in and about the Premises; (h) to close or restrict access to the
Building at all times other than Normal Business Hours subject to Tenant's right
to admittance at all times under such regulations as Landlord may prescribe from
time to time, or to close (temporarily or permanently) any of the entrances to
the Building; (i) to change the arrangement and/or location of entrances of
passageways, doors and doorways, corridors, elevators, stairs, toilets and
public parts of the Building; (j) if Tenant has vacated the Premises during the
last six (6) months of the Lease Term, to perform additions, alterations and
improvements to the Premises in connection with a reletting or anticipated
reletting thereof without being responsible or liable for the value or
preservation of any then existing improvements to the Premises; and (k) to grant
to anyone the exclusive right to conduct any business or undertaking in the
Building. Landlord, in accordance with Article 15 hereof, shall have the right
to enter the Premises in connection with the exercise of any of the rights set
forth herein and such entry into the Premises and the performance of any work
therein shall not constitute a constructive eviction or entitle Tenant to any
abatement or reduction of Rent by reason thereof.

                      ARTICLE 37:  SURRENDER OF PREMISES

     At the expiration or earlier termination of this Lease or Tenant's right of
possession hereunder, Tenant shall remove all Tenant's Property from the
Premises, remove all Required Removables designated by Landlord at the time of
initial consent to Tenant's alterations and quit and surrender the Premises to
Landlord, broom clean, and in good order, condition and repair, ordinary wear
and tear excepted.  If Tenant fails to remove any of Tenant's Property within
one (1) day after the termination of this Lease or Tenant's right to possession
hereunder, Landlord, at Tenant's sole cost and expense, shall be entitled to
remove and/or store such Tenant's Property and Landlord shall in no event be
responsible for the value, preservation or safekeeping thereof.  Tenant shall
pay Landlord, upon demand, any and all expenses caused by such removal and all
storage charges against such property so long as the same shall be in the
possession of Landlord or under the control of Landlord.  In addition, if Tenant
fails to remove any Tenant's Property from the Premises or storage, as the case
may be, within ten (10) days after written notice from Landlord, Landlord, at
its option, may deem all or any part of such Tenant's Property to have been
abandoned by Tenant and title thereof shall immediately pass to Landlord.

                          ARTICLE 38:  MISCELLANEOUS

          A.  If any term or provision of this Lease, or the application thereof
to any person or circumstance shall, to any extent, be invalid or unenforceable,
the remainder of this Lease, or the application of such term or provision to
persons or circumstances other than those as to which it is held invalid or
unenforceable, shall not be affected thereby, and each term and provision of
this Lease shall be valid and enforced to the fullest extent permitted by law.
This Lease represents the result of negotiations between Landlord and Tenant,
each of which has been (or has had opportunity to be) represented by counsel of
its own selection, and neither of which has acted under duress or compulsion,
whether legal, economic or otherwise.  Consequently, Landlord and Tenant agree
that the language in all parts of the Lease shall in all cases be construed as a
whole according to its fair meaning and neither strictly for nor against
Landlord or Tenant.

          B.  Landlord agrees that Tenant may record a memorandum of this Lease.

          C.  This Lease and the rights and obligations of the parties hereto
shall be interpreted, construed, and enforced in accordance with the laws of the
state of Washington.

          D.  Events of "Force Majeure" shall include strikes, riots, acts of
God, shortages of labor or materials, war, governmental law, regulations or
restrictions and any other cause (other than financial ability) that is beyond
the reasonable control of Landlord.  Whenever a period of time is herein
prescribed for the taking of any action by Landlord, Landlord shall not be
liable or responsible for, and there shall be excluded from the computation of
such period of time, any delays due to events of Force Majeure, except as
otherwise set forth in this Lease.

          E.  Landlord shall have the right to transfer and assign, in whole or
in part, all of its rights and obligations hereunder and in the Building and
Property referred to herein, and in such event and upon such transfer Landlord
shall be released from any further obligations hereunder, and Tenant agrees to
look solely to such successor in interest of Landlord for the performance of
such obligations.

          F.  Tenant hereby represents to Landlord that it has dealt directly
with and only with the Broker as a broker in connection with this Lease.  Tenant
agrees to indemnify and hold Landlord and the Landlord Related Parties harmless
from all claims of any brokers other than the Broker claiming to have
represented Tenant in connection with this Lease.  Landlord agrees to indemnify
and hold Tenant and the Tenant Related Parties harmless from all claims of the
Broker and any brokers 

                                     -54-
<PAGE>
 
claiming to have represented Landlord in connection with this Lease. Landlord
agrees to pay a brokerage commission to Broker in accordance with the terms of a
written commission agreement between Landlord and Broker.

          G.  Agency Disclosure.  Broderick Group, Inc. represents both Landlord
and Tenant in connection with this Lease.  Landlord and Tenant hereby confirm
that they were timely advised of the dual representation, that they consent to
the same, and that they do not expect said broker to disclose to either party
the confidential information of the other party.  Landlord shall pay Broderick
Group, Inc. a commission of Four and 50/100 Dollars ($4.50) per rentable square
foot of the Initial Premises, which commission shall be earned and paid one-half
( 1/2) upon execution of this Lease and one-half ( 1/2) upon Tenant's occupancy
of the Premises, provided that no payment shall be made until the start of
construction (as defined in Article 4 above).  No commission shall be paid on
any option or expansion space except for expansion space with a Rent
Commencement Date within the first twelve (12) months of the Initial Term.

          H.  Landlord and Tenant, by their execution of this Lease, each
acknowledge and agree that they have timely received a pamphlet on the law of
real estate agency as required under RCW 18.86.030(1)(f).

          I.  If there is more than one Tenant, or if the Tenant is comprised of
more than one person or entity, the obligations hereunder imposed upon Tenant
shall be joint and several obligations of all such parties.  All notices,
payments, and agreements given or made by, with or to any one of such persons or
entities shall be deemed to have been given or made by, with or to all of them.

          J.  In the event Tenant is a corporation (including any form of
professional association), partnership (general or limited), or other form of
organization other than an individual (each such entity is individually referred
to herein as an "Organizational Entity"), then Tenant hereby covenants, warrants
and represents:  (1) that such individual is duly authorized to execute or
attest and deliver this Lease on behalf of Tenant in accordance with the
organizational documents of Tenant; (2) that this Lease is binding upon Tenant;
(3) that Tenant is duly organized and legally existing in the state of its
organization, and is qualified to do business in the state in which the Premises
is located; and (4) that the execution and delivery of this Lease by Tenant will
not result in any breach of, or constitute a default under any mortgage, deed of
trust, lease, loan, credit agreement, partnership agreement or other contract or
instrument to which Tenant is a party or by which Tenant may be bound.  If
Tenant is an Organizational Entity, upon request, Tenant will, prior to the
Commencement Date, deliver to Landlord true and correct copies of all
organizational documents of Tenant, including, without limitation, copies of an
appropriate 

                                     -55-
<PAGE>
 
resolution or consent of Tenant's board of directors or other appropriate
governing body of Tenant authorizing or ratifying the execution and delivery of
this Lease, which resolution or consent will be duly certified to Landlord's
satisfaction by an appropriate individual with authority to certify such
documents, such as the secretary or assistant secretary or the managing general
partner of Tenant.

          K.  Tenant acknowledges that the financial capability of Tenant to
perform its obligations hereunder is material to Landlord and that Landlord
would not enter into this Lease but for its belief, based on its review of
Tenant's financial statements, that Tenant is capable of performing such
financial obligations.  Tenant hereby represents, warrants and certifies to
Landlord that its financial statements previously furnished to Landlord were at
the time given true and correct in all material respects and that there have
been no material subsequent changes thereto as of the date of this Lease.  At
any time during the Lease Term, Tenant shall provide Landlord, upon ten (10)
days' prior written notice from Landlord, with a current financial statement and
financial statements of the two (2) years prior to the current financial
statement year and such other information as Landlord or its Mortgagee may
reasonably request in order to create a "business profile" of Tenant and
determine Tenant's ability to fulfill its obligations under this Lease.  Such
statement shall be prepared in accordance with generally accepted accounting
principles and, if such is the normal practice of Tenant, shall be audited by an
independent certified public accountant, and shall be delivered subject to
reasonable nondisclosure agreements acceptable to Tenant.

          L.  Except as expressly otherwise herein provided, with respect to all
required acts of Tenant and Landlord, time is of the essence of this Lease.
This Lease shall create the relationship of Landlord and Tenant between the
parties hereto.

          M.  This Lease and the covenants and conditions herein contained shall
inure to the benefit of and be binding upon Landlord and Tenant and their
respective permitted successors and assigns.

          N.  Notwithstanding anything to the contrary contained in this Lease,
the expiration of the Lease Term, whether by lapse of time or otherwise, shall
not relieve Tenant from Tenant's obligations accruing prior to the expiration of
the Lease Term, and such obligations shall survive any such expiration or other
termination of the Lease Term.

          O.  The headings and titles to the paragraphs of this Lease are for
convenience only and shall have no affect upon the construction or
interpretation of any part hereof.

                                     -56-
<PAGE>
 
          P.  Landlord has delivered a copy of this Lease to Tenant for Tenant's
review only, and the delivery hereof does not constitute an offer to Tenant or
option.  This Lease shall not be effective until an original of this Lease is
executed by both Landlord and Tenant.

          Q.  Quiet Enjoyment.  Tenant shall, and may peacefully have, hold, and
enjoy the Premises, subject to the other terms of this Lease (including, without
limitation, Article 32 hereof), provided that Tenant pays the Rent herein
recited to be paid by Tenant and performs all of Tenant's covenants and
agreements herein contained.  This covenant and any and all other covenants of
Landlord shall be binding upon Landlord and its successors only during its or
their respective periods of ownership of the Landlord's interest hereunder.

          R.  Americans With Disabilities Act.  Landlord will insure that at the
Commencement Date the Common Areas of the Building, and the shell and core,
shall be in compliance with the Americans With Disabilities Act.  Tenant shall
be responsible for seeing that the Tenant Improvements are designed in
accordance with the Americans With Disabilities Act.

          S.  Roof Rights.  Landlord shall allow Tenant to place one or more
satellite dishes or antennas on the roof of the Building, at market rates, and
subject to such other terms and conditions as Landlord and Tenant may reasonably
agree.  The agreed market rates for the first five (5) years of the Lease term
are attached hereto as Exhibit G.  Such rates shall thereafter adjust to market.
Tenant shall be solely responsible for obtaining all permits and approvals in
connection with such satellite dishes or antennas, and the costs of such permits
and approvals and the installation costs shall be borne solely by Tenant, which
amount Tenant may charge against the Allowance.

          T.  Environmental

              (1)  Hazardous Materials. Tenant shall not (either with or
without negligence) cause or permit the escape, disposal or release of any
biologically or chemically active or other hazardous substances, or materials.
Tenant shall not knowingly allow the storage or use of such substances or
materials in any manner not sanctioned by law or by the highest standards
prevailing in the industry for the storage and use of such substances of
materials, nor allow to be brought into the Project any such materials or
substances except to use for general office purposes and the other permitted
uses in the ordinary course of Tenant's business. Without limitation, hazardous
substances and materials shall include those described in the Comprehensive
Environmental Response, Compensation and Liability Act of 1980, as amended, 42
U.S.C. Section 9601 et seq., any applicable state or local laws and the

                                     -57-
<PAGE>
 
regulations adopted under these acts. If any governmental agency or lender (in
its reasonable judgment) shall ever require testing to ascertain whether or not
there has been any release of hazardous materials and such testing indicates
that Tenant has violated any of the terms and conditions of this section, then,
in addition to any other rights and remedies available hereunder or at law or in
equity, the reasonable costs of such testing shall be reimbursed by Tenant to
Landlord upon demand as additional charges. In addition, Tenant shall execute
affidavits, representations and the like from time to time at Landlord's request
concerning Tenant's best knowledge and belief regarding the presence of
hazardous substances or materials on the Premises. In all events, Tenant shall
indemnify Landlord in the manner elsewhere provided in this Lease from any
release of hazardous materials on the Premises occurring while Tenant is in
possession, or elsewhere if caused by Tenant or persons acting under Tenant. The
within covenants shall survive the expiration or earlier termination of the
Lease Term.

              (2)  Landlord's Representation. To the actual knowledge of
Landlord, after reasonable investigation, neither the Building nor the
underlying land contains any hazardous substances or materials in excess of
levels permitted by applicable laws.

          U.  Competitors.  Landlord shall not lease space in the Building, or
in Buildings 4 or 5 if Tenant then has leased at least 30,000 rentable square
feet in such building, to the following competitors of Tenant (unless the space
leased to such party `exceeds ten thousand (10,000) rentable square feet):
Pivotal, Siebel Systems, Vantive, Aurum, Clarify and SalesLogix.  Landlord shall
notify Tenant in writing if Landlord is requested to consent to a sublease to
any of the foregoing entities.  Tenant shall be entitled to update such list of
excluded competitors, as reasonable necessary from time to time, and subject to
Landlord's reasonable approval to include other entities whose primary business
is the design, manufacture and sale of software focused in the area of customer
information management.

          V.  Estoppel Certificates.  In addition to the obligations of Tenant
under the Lease, Tenant agrees that it will from time to time upon request of
Landlord, within ten (10) days after the date of such request, execute and
deliver to such persons as Landlord shall request an estoppel certificate or
other similar statement certifying that:  i)  the Tenant is presently solvent
and free from reorganization and/or bankruptcy and is in occupancy, open, and
conducting business in the Premises, (ii) the operation and use of the Premises
do not involve the generation, treatment, storage, etc. of hazardous substance,
etc. (except as permitted in the Lease), (iii) the rent payable per year, (iv)
the Lease represents the entire agreement between the parties, (v) the
expiration date, (vi) all conditions to be 

                                     -58-
<PAGE>
 
performed by the Landlord have been satisfied, (vii) all required contributions
by Landlord to Tenant on account of Tenant improvements have been received,
(viii) no rental has been paid more than one month in advance and no security
has been deposited with Landlord except as otherwise noted and, (ix) the
rentable square footage of the Premises.

payable in monthly installments (the "Monthly Rent") as set forth below:

          3.1.1  $6,700.24 for the period from March 15, 1996 through March 31,

Monthly Rent shall be payable in advance on the first day of each month without

Tenant's Electrical Charge for the Base Year. The Base Year is calendar year

Premises to the total number of rentable square feet subject to the Master Lease
(i.e. 15,664 rentable square feet divided by 23,468 rentable square feet). Such
payments by Subtenant, together with any and all other amounts payable by

Sublandlord's receipt thereof from Landlord. At the request (and cost) of
Subtenant, Sublandlord agrees to exercise its right to contest Landlord's
determination of Expenses as provided in the Master Lease.

     If either Sublandlord or Subtenant require extraordinary electrical use
with respect to the portion of the Master Space occupied by it, the parties

     Any and all sums Subtenant is obligated to pay under the terms of this
Sublease shall be construed as rent obligations in addition to the Monthly Rent
set forth in this Sublease. In addition, such additional rent shall include a
service charge of Twenty-Five Dollars ($25.00) for each of Subtenant's
dishonored checks returned by the institution on which said checks are drawn.
If, at any time during the term of this Sublease, Subtenant has tendered payment
by check and Subtenant's bank has returned more than one such payment for any
reason, including insufficient funds Sublandlord may, at its option, require
that all future payments be made by cashier's check.

4.   SECURITY DEPOSIT

     Upon execution of this Sublease, Subtenant shall deposit the sum of Twenty-
One Thousand Seven Hundred Thirty-Three and 80/100 Dollars ($21,733.80) by
delivery of good funds to Pacific Real Estate Partners, which amount shall be
paid to Sublandlord immediately upon satisfaction or waiver of the conditions
set forth in Section 40 below, and shall be held by Sublandlord as a "Security
Deposit" for Subtenant's performance of all of the terms, covenants and
conditions of this Sublease. If Subtenant defaults under any provision of this
Sublease, Sublandlord may (but shall not be required to) use, apply or retain
all or any part of this Security Deposit for the payment of any amount
Sublandlord may spend by reason of Subtenant's default or to compensate
Sublandlord for any loss or damage Sublandlord may suffer because of Subtenant's
default. If any portion of the Security Deposit is so used or applied, Subtenant
shall, within ten (10) days after written demand, deposit cash with Sublandlord
in an amount sufficient to restore the Security Deposit to its original amount.
Sublandlord is not required to keep the Security Deposit separate from its
general funds, and Subtenant is not entitled to interest on the Security
Deposit. If Subtenant performs each of its obligations under this Sublease, the
Security Deposit, or any balance thereof, shall be applied by Sublandlord to the
Monthly Rent due for the last month of the Term.

cost and expense of Subtenant and, except for Subtenant's trade fixtures,
furniture and equipment, shall become the property of Sublandlord and shall
remain in and be surrendered with the Premises at the termination of this
Sublease. However, Sublandlord, may require Subtenant to remove from the
Premises any or all improvements, fixtures, alterations or additions upon the
termination of the Sublease if Landlord requires the removal of such items in
accordance with the Master Lease and Subtenant shall promptly do so and shall
repair all damages occasioned by such removal and return the Premises to their
original condition at the commencement of this Sublease, all at Subtenant's sole
cost and expense.

     All improvements, alterations and additions undertaken by Subtenant shall
be performed by a contractor approved in advance by Sublandlord, according to

this respect, Subtenant may elect to defer the professional carpet cleaning
within the Remaining Premises until after Subtenant has completed its
anticipated improvements.

6.   CONDITION OF PREMISES

     Subtenant has thoroughly inspected the Premises and accepts them in their
present condition, AS IS WITH ALL FAULTS, subject, however, to the work to be

furnish any of Landlord's Services and will not be liable for any disruption or
failure of such services. Upon receipt of written complaint from Subtenant,
Sublandlord shall make demand upon Landlord to take all appropriate action for
the correction of any defect, inadequacy or insufficiency in Landlord's
provision of Landlord's Services. If necessary, Sublandlord shall enforce its
rights under the Master Lease to Landlord's Services for Subtenant's benefit by

<PAGE>
 
     Sublandlord shall mitigate its damage by making reasonable efforts to relet
the Premises on reasonable terms. Sublandlord may relet for a shorter or longer
period of time than the Term and make reasonably necessary repairs and
alterations. All sums collected from reletting shall be applied first to
Sublandlord's expenses of reletting described in Section 13.5, and then to the
                                                 ------------                 
payment of amounts due from Subtenant to Sublandlord under this Sublease.

expense, keep in full force and effect the insurance required under Section 16
                                                                    ----------
of the Master Lease, including, without limitation, the following insurance:

     14.1  LIABILITY INSURANCE

     A policy of general commercial liability insurance satisfying each and
every requirement of the Master Lease and naming both Sublandlord and Landlord
as additional insureds. Such liability policy shall (a) insure against any and
all claims or liability arising out of the use or maintenance of the Property
under this Sublease, in an amount not less than $1,000,000.00 per occurrence
covering bodily injury to persons, including death, and damage to property; (b)
insure the hazards of the Property and Subtenant's operations thereon,
independent contractors, contractual liability (covering all indemnity
provisions of this Sublease); and (c) contain a cross-liability provision and a
provision that the insurance provided Sublandlord and Landlord hereunder shall
be primary and non-contributing with any other insurance.

     14.2  PROPERTY DAMAGE INSURANCE

     A fire and extended coverage insurance policy on the improvements to the
Premises satisfying the requirements of the Master Lease and naming both
Sublandlord and Landlord as additional insureds as their interests may appear.
Such policy shall (a) be a standard form of property insurance insuring against
the perils of fire, extended coverage, vandalism, malicious mischief, special
extended coverage ("All-Risk") and sprinkler leakage, and (b) be upon all
property owned by Subtenant, or for which Subtenant is legally liable, or that
was installed at Subtenant's expense, and that is located at the Premises,
including, but not limited to, furniture, fittings, installations, fixtures, and
any other personal property of Subtenant, in an amount not less than ninety
percent (90%) of the full replacement cost thereof.

<PAGE>
 
     14.3  GENERAL REQUIREMENTS

     All policies shall be written in a form (including amount of deductibles,
if any) satisfactory to Sublandlord and shall be taken out with insurance
companies holding a General Policyholders Rating of "A+" and a Financial Rating
of "XII" or better, as set forth in the most current issue of Best's Insurance
Reports, but in any event not less than the rating required under the Master
Lease.

     At the time of execution of this Sublease, Subtenant shall deliver to
Sublandlord copies of policies or certificates complying with this Sublease, in
form satisfactory to Sublandlord and Landlord. No such policy shall be
cancelable or reducible in coverage except after thirty (30) days prior written
notice to Sublandlord and Landlord. If Subtenant fails to obtain, maintain
and/or provide evidence of insurance required hereunder, Sublandlord may obtain
the same and Subtenant shall, upon demand, reimburse Sublandlord for the cost
thereof. No such action by Sublandlord or reimbursement from Subtenant shall be
a waiver of default or other remedies. In no event shall the limits of such
policies be considered as limiting liability of Subtenant under this Sublease.

     14.4  SUBLANDLORD INSURANCE

     Sublandlord agrees that it will continue to maintain insurance on the
portion of the Master Space not included in the Premises in accordance with the
requirements of the Master Lease. Subtenant shall be named as an additional
insured on the liability insurance policies maintained by Sublandlord under the
Master Lease.

15.  WAIVER OF RECOVERY

     Sublandlord and Subtenant each release and relieve the other, and waive
their entire rights of recovery for, loss or damage to property located within
or constituting a part or all of the Property to the extent that the loss or
damage is covered by (a) the injured party's insurance, or (b) the insurance the
injured party is required to carry under Section 14 whichever is greater. This
                                         ----------                           
waiver applies whether or not the loss is due to the negligent acts or omissions
of Sublandlord or Subtenant, or their respective officers, directors, employees,
agents, contractors, or invitees. Each of Sublandlord and Subtenant shall have
their respective property insurers endorse the applicable insurance policies to
reflect the foregoing waiver of claims, provided, however, that the endorsement
shall not be required if the applicable policy of insurance permits the named
insured to waive rights of subrogation on a blanket basis, in which case the
blanket waiver shall be acceptable.

                                      -12-
<PAGE>
 
16.  RISK

     All of Subtenant's personal property of any kind or description whatsoever
in the Property shall be at Subtenant's sole risk. Sublandlord and Landlord
shall not be liable for any damage done to or loss of such personal property or
damage or loss suffered by the business or occupation of Subtenant arising from
any acts or neglect of co-subtenants or other occupants of the Building, or of
any other persons, or from bursting, overflowing or leaking of water, sewer or
steam pipes, or from the heating or plumbing or sprinkler fixtures, or from
electric wires, or from gas, or odors, or caused in any other manner whatsoever

18.  INDEMNIFICATION

     Subtenant will defend, indemnify and hold harmless Sublandlord and Landlord
from any claim, liability or suit, including attorney fees, on behalf of any
party for any injury or damage occurring in or about the Master Space where such
damage or injury was caused by any act, omission, negligence or intentional act
of Subtenant or by Subtenant's agents, employees, servants, customers, clients,
contractors, or invitees. Sublandlord will defend, indemnify and hold harmless
Subtenant from any claim, liability or suit, including attorney fees, on behalf
of any party for any bodily injury or property damage occurring in or about the
Master Space to the extent the damage or injury was caused by the negligence of
Sublandlord, its agents, employees, servants, customers or invitees.

     The indemnification obligations contained in this Section 18 or elsewhere
                                                       ----------             
in this Sublease shall not be limited by any worker's compensation, benefit or
disability laws. For the sole purpose of effectuating the indemnification
obligations under this Sublease and not for the benefit of any third parties,
Sublandlord and Subtenant each hereby waives any immunity that it may have under
the Industrial Insurance Act, Title 51 RCW and similar worker's compensation,
benefit or disability laws.

     SUBLANDLORD AND SUBTENANT ACKNOWLEDGE BY THEIR EXECUTION OF THIS SUBLEASE

19.  CASUALTY & CONDEMNATION

     Under certain circumstances described in the Master Lease, either Landlord
or Sublandlord may terminate the Master Lease if there is a fire or other
casualty damaging the Building or the Premises, or if there is a condemnation
affecting the Building. Any such termination will automatically terminate this
Sublease. Sublandlord's obligation to repair any damage to the Premises is
limited to its obligation to do so under the Master Lease. Rent will abate in
proportion to the loss of use of the Premises caused by fire or other casualty.
In the event of fire or other casualty damaging the Building or the Premises,
Subtenant shall have the right to terminate this Sublease on the same terms and
conditions, and subject to the same standards, as Sublandlord's rights to
terminate as a result of fire or other casualty under the Master Lease.
Subtenant may terminate this Sublease under such circumstances even if
Sublandlord or Landlord do not elect to terminate the Master Lease.

breach or default under the Master Lease which has not been remedied in full.

any modification or amendment of the Master Lease that adversely affects the

would cause the Master Lease to be terminated or forfeited by reason of any
right of termination or forfeiture reserved or vested in Landlord under the
Master Lease.

           RIGHTS

all of the terms and conditions of the Master Lease (i) applicable to the
portion of the Master Space which is not part of the Premises, and (ii) which

remedy available to Subtenant under this Sublease or under applicable law due to

pursuant to the terms of this Sublease (the "Remaining Space"), which Remaining

Section 30. A portion of the Remaining Space is subleased by Sublandlord from
- ----------                                                                    
Lockwood Lozier Custom Homes Company, Inc. under a Sublease dated June 13, 1995
(the "LLCHC Space").  In connection with the Right of First Refusal as it
applies to the LLCHC Space, Subtenant shall take an assignment of that sublease
upon exercise of the Right of First Refusal as to such space.

     30.2  TERM OF FIRST RIGHT OF REFUSAL

     The term of this Right of First Refusal shall commence on the effective

     Subtenant may elect to exercise its Right of First Refusal by giving
Sublandlord written notice of such election on or before the fifth (5th) day
following delivery of Sublandlord's Notice. Subtenant's failure to give written
notice of an election to exercise its Right of First Refusal within five (5) day
period shall be deemed a waiver of its Right of First Refusal only with respect
to the Offered Space.

     30.5  TERMS OF THE SUBLEASE

     Upon Subtenant's exercise of the Right of First Refusal, Sublandlord shall
lease to Subtenant and Subtenant shall lease from Sublandlord the Offered Space

execute such lease shall not affect Tenant's rights with respect to the Offered
Space.

     30.6  SUBLANDLORD'S RIGHT TO LEASE

     If Subtenant does not indicate in writing its election to lease the Offered
Space within the time period described in Section 30.4 above, Sublandlord
                                          ------------

Offered Space; provided (i) the transaction is consummated at a rental rate of
not less than the rental rate specified in the Basic Business Terms and on other
economic terms no more favorable than the other Basic Business Terms set forth
in Sublandlord's Notice; and (ii) the transaction is consummated on or before
the one hundred twentieth (120th) day following delivery of Sublandlord's
Notice. Any lease or grant of a right of occupancy affecting the Offered Space
not meeting the criteria of the prior sentence shall be deemed a new
determination by Sublandlord to lease the Offered Space and may not be
consummated unless Subtenant is again offered the right to lease such Offered
Space in accordance with the provisions of this Right of First Refusal.

     30.7  EXPANSION

remainder of the Master Space on the first floor of the Building. However, the

configuration or number of buildings in the Project, provided only that upon
such 

                                      -2-
<PAGE>
 
modification or alteration, the Project Area as set forth in Section l(f)
shall be adjusted to reflect such modification or alteration.

3.   TERM

     The Commencement Date listed in Section 1 of this Lease represents an
estimate of the Commencement Date. This Lease shall commence on the estimated
Commencement Date if tenant improvement work required of Landlord pursuant to
this Lease ("Landlord's Work") is substantially completed (as that term is used
in the construction industry) by such date, but otherwise the Commencement Date
shall be first to occur of the following events (i) the date on which Landlord
notifies Tenant that Landlord's Work is substantially complete, (ii) the date on
which Tenant takes possession or commences beneficial occupancy of the Premises,
or (iii) if substantial completion of Landlord's Work is delayed due to Tenant's
failure to perform its obligations under this Lease, then the date determined by
Landlord as the date upon which Landlord's Work would have been substantially
completed, but for Tenant's failure to perform. If this Commencement Date is
later than the Section 1 Commencement Date, this Lease shall not be void or
voidable, nor shall Landlord be liable to Tenant for any loss or damage
resulting therefrom. Notwithstanding the foregoing, if Tenant is not permitted
access to use the Premises for the purposes described in Section l(d) within
thirty (30) days of the Commencement Date, this Lease shall be voidable at the
discretion of the Tenant by notice given by Tenant to Landlord within three (3)
days after expiration of such thirty (30) day period. Landlord shall confirm the
Commencement Date by written notice to Tenant. This Lease shall be for a term
("Lease Term") beginning on the Commencement Date and ending on the Expiration
Date, unless extended or sooner terminated in accordance with the terms of this
Lease. All provisions of this Lease, other than those relating to payment of
Base Monthly Rent and Additional Rent, shall become effective upon the first to
occur of (a) the date that Tenant or its officers, agents, employees or
contractors is first present on the Premises, whether for inspection,
construction, installation or other purposes, or (b) such other date, if any, as
may be specified in an Exhibit hereto.

4.   RENT

     A.   BASE RENT

     Tenant shall pay Landlord monthly base rent in the initial amount in
Section 1 which shall be payable monthly in advance on the first day of each and
every calendar month ("Base Monthly Rent") provided, however, the first month's
Base Monthly Rent and Tenant's Share of Expenses is due and payable upon
execution of this Lease. If the term of this Lease contains any rental abatement
period, Tenant hereby agrees 

                                      -3-
<PAGE>
 
that if Tenant breaches the Lease and fails to cure such breach within the
applicable cure period, if any, and/or abandons the Premises before the end of
the Lease term, or if Tenant's right to possession is terminated by Landlord
because of Tenant's breach of the Lease, the rental abatement period shall be
deemed extinguished, and there shall be immediately due from Tenant to Landlord,
in addition to any damages otherwise due Landlord under the terms and conditions
of the Lease, Base Monthly Rent prorated for the entirety of the rental
abatement period at the average Base Monthly Rent for the Lease, plus any and
all other charges (such as Expenses) that were abated during such rental
abatement period.

     For purposes of Section 467 of the Internal Revenue Code, the parties to
this Lease hereby agree to allocate the stated Rents, provided herein, to the
periods which correspond to the actual Rent payments as provided under the terms
and conditions of this agreement.

     B.   RENT ADJUSTMENT

          1)  COST OF LIVING ADJUSTMENT

     If Section i.i(l) is initialed, the Base Monthly Rent shall be subject to
increase on each annual anniversary of the first day of the first full calendar
month after the Commencement Date (the "Anniversary Date"). The base for
computing the increase is the Consumer Price Index All Urban Consumers U.S. City
Average (1982-84=100), published by the United States Department of Labor,
Bureau of Labor Statistics ("Index"), which is in effect on the ninetieth (90th)
day preceding the Commencement Date ("Beginning Index"). The Index published and
in effect on the ninetieth (90th) day preceding each Anniversary Date
("Extension Index") is to be used in determining the amount of the increase from
one year to the next. Beginning with the Rent due on and after the first
anniversary the Base Monthly Rent shall be increased to equal the product
achieved by multiplying the full Base Monthly Rent due with respect to the month
immediately preceding such anniversary date by a fraction. On the first
Anniversary Date, the numerator of the fraction will be the Extension Index and
the denominator will be the Beginning Index. On the second and any subsequent
Anniversary Date, the numerator of the fraction will be the current Extension
Index and the denominator will be the Extension Index used to calculate the
previous year's Base Monthly Rental increase. If there is a decline from one
lease year to the next in the Extension Index, the Base Monthly Rent due during
the subsequent lease year shall equal the Base Monthly Rent due during the then
present lease year.

     If the Index is changed so that the base year differs from that in effect
when the term commences, the Index shall be converted in accordance with the
conversion factor published by the United States Department of Labor, Bureau of
Labor 

                                      -4-
<PAGE>
 
Statistics. If the Index is discontinued or revised during the term, such other
government index or computation with which it is replaced shall be used in order
to obtain substantially the same result as would be obtained if the Index had
not been discontinued or revised.

          2)  STEP INCREASE

     If Section l.i.(2) is initialed, Base Monthly Rent shall be increased
periodically to the amounts and at the times set forth in Section 1.I.(2).

     C.   EXPENSES

     The purpose of this Section 4.3 is to ensure that Tenant bears a share of
all Expenses related to the use, maintenance, ownership, repair or replacement,
and insurance of the Project.  Accordingly, beginning on January 1, 1998, Tenant
shall each month pay to Landlord one-twelfth (1/12) of Tenant's Share of
Expenses related to the Project. As used in this Lease, "Tenant's Share" shall
mean the Premises Area, as defined in Section l.e, divided by the Project Area,
as defined in Section l.f, and "Tenant's Share of Expenses" shall mean total
Expenses for the Project, multiplied by Tenant's Share, minus the Annual Expense
Base set forth in Section 1(j). Landlord may specially allocate individual
expenses where and in the manner necessary, in Landlord's discretion, to
appropriately reflect the consumption of the expense or service. For example
where some but not all premises in the Project have HVAC, Landlord may
reallocate Project Expenses for HVAC to all premises utilizing HVAC to be
apportioned on a per square foot basis, or could allocate to each premises
utilizing HVAC the cost of maintaining that space's individual unit. In the
event the average occupancy level of the Project for any year is less than
ninety five percent (95%), the actual Expenses for such year shall be
proportionately adjusted to reflect those costs which Landlord estimates would
have been incurred, had the Project been ninety five percent (95%) occupied
during such year.

          1)  EXPENSES DEFINED

     The term "Expenses" shall mean all costs and expenses of the ownership,
operation, maintenance, repair or replacement, and insurance of the Project,
including without limitation, the following costs:

          (a) All supplies, materials, labor, equipment, and utilities used in
or related to the operation and maintenance of the Project,

          (b) All maintenance, management, janitorial, legal, accounting,
insurance, and service agreement costs related to the Project;

                                      -5-
<PAGE>
 
          (c) All maintenance, replacement and repair costs relating to the
areas within or around the Project, including, without limitation, air
conditioning systems, sidewalks, landscaping, service areas, driveways, parking
Areas (including resurfacing and restriping parking areas), walkways, building
exteriors (including painting), signs and directories, repairing and replacing
roofs, walls, etc. These costs may be included either based on actual
expenditures or the use of an accounting reserve based on past cost experience
for the Project.

          (d) Amortization (along with reasonable financing charges) of capital
improvements made to the Project which may be required by any government
authority or which will improve the operating efficiency of the Project
(provided, however, that the amount of such amortization for improvements not
mandated by government authority shall not exceed in any year the amount of
costs reasonably determined by Landlord in its sole discretion to have been
saved by the expenditure either through the reduction or minimization of
increases which would have otherwise occurred).

          (e) Real Property Taxes including all taxes, assessments (general and
special) and other impositions or charges which may be taxed, charged, levied,
assessed or imposed upon all or any portion of or in relation to the Project or
any portion thereof, any leasehold estate in the Premises or measured by Rent
from the Premises, including any increase caused by the transfer, sale or
encumbrance of the Project or any portion thereof. "Real Property Taxes" shall
also include any form of assessment, levy, penalty, charge or tax (other than
estate, inheritance, net income, or franchise taxes) imposed by any authority
having a direct or indirect power to tax or charge, including, without
limitation, any city, county, state federal or any improvement or other
district, whether such tax is (l) determined by the value of the Project or the
Rent or other sums payable under this Lease; (2) upon or with respect to any
legal or equitable interest of Landlord in the Project or any part thereof; (3)
upon this transaction or any document to which Tenant is a party creating a
transfer in any interest in the Project, (4) in lieu of or as a direct
substitute in whole or in part of or in addition to any real property taxes on
the Project, (5) based on any parking spaces or parking facilities provided in
the Project, or (6) in consideration for services, such as police protection,
fire protection, street, sidewalk and roadway maintenance, refuse removal or
other services that may be provided by any governmental or quasi-governmental
agency from time to time which were formerly provided without charge or with
less charge to property owners or occupants.

          (f) Landlord agrees that Expenses as defined in Section 4(c) shall not
include leasing commissions; payments of principal and interest on any
mortgages, deeds of trust or other encumbrances upon the Project; depreciation
of the 

                                      -6-
<PAGE>
 
capital cost of capital improvements except as provided at 4(c)(1)(d);
Landlord's executive salaries, management fees in excess of market rates; costs
resulting from defective design or construction of the Project; costs incurred
in connection with entering into new leases; or costs of disputes under existing
leases. In no event shall Expenses include any charge for which Landlord
receives reimbursement from insurance or from another Tenant, nor shall any item
of Expense be counted more than once, nor shall Landlord collect more than one
hundred percent (100%) of Expenses.

          2)  ANNUAL ESTIMATE OF EXPENSES, TENANT'S SHARE

     At the commencement of each calendar year, beginning with calendar year
1998, Landlord shall estimate Tenant's share of Expenses for the remainder of
the calendar year, and at the commencement of each calendar year thereafter,'
Landlord shall estimate Tenant's Share of Expenses for the coming year by
multiplying the estimated annual Project Expenses by Tenant's Share and
subtracting the Annual Expense Base.

          3)  MONTHLY PAYMENT OF EXPENSES

     Tenant shall pay to Landlord, monthly in advance, as Additional Rent, one-
twelfth (1/12) of the Annual Estimate of Tenant's Share of Expenses beginning on
January 1, 1998. As soon as practical following each calendar year, Landlord
shall prepare an accounting of actual Expenses incurred during the prior
calendar year and such accounting shall reflect Tenant's Share of Expenses. If
the Additional Rent paid by Tenant under this Section 4.c.3 during the preceding
calendar year was less than the actual amount of Tenant's Share of Expenses,
Landlord shall so notify Tenant and Tenant shall pay such amount to Landlord
within 30 days of receipt of such notice. Such amount shall be deemed to have
accrued during the prior calendar year and shall be due and payable from Tenant
even though the term of this Lease has expired or this Lease has been terminated
prior to Tenant's receipt of this notice. Tenant shall have thirty (30) days
from receipt of such notice to contest the amount due, failure to so notify
Landlord shall represent final determination of Tenant's Share of Expenses. If
Tenant's payments were greater than the actual amount, then such overpayment
shall be credited by Landlord to Tenant's Share of Expenses due under this
Section 4.c.3, or if the Lease has expired or been terminated, any overpayment
net of other sums due from Tenant to Landlord shall be refunded to Tenant by
check.

          4)  RENT WITHOUT OFFSET AND LATE CHARGE

     As used herein, "Rent" shall mean all monetary sums due from Tenant to
Landlord. All Base Monthly Rent shall be paid by Tenant to Landlord without
prior 

                                      -7-
<PAGE>
 
notice or demand in advance on the first day of every calendar month, at the
address shown in Section 1, or such other place as landlord may designate in
writing from time to time. Whether or not so designated, all other sums due from
Tenant under this Lease shall constitute Additional Rent, payable without prior
notice or demand when specified in this Lease, but if not specified, then within
ten (10) days of demand. All Rent shall be paid without any deduction or offset
whatsoever. All Rent shall be paid in lawful currency of the United States of
America. Proration of Rent due for any partial month shall be calculated by
dividing the number of days in the month for which Rent is due by the actual
number of days in that month and multiplying by the applicable monthly rate.
Tenant acknowledges that late payment by Tenant to Landlord of any Rent or other
sums due under this Lease will cause Landlord to incur costs not contemplated by
this Lease, the exact amount of such cost being extremely difficult and
impracticable to ascertain. Such costs include, without limitation, processing
and accounting charges and late charges that may be imposed on Landlord by the
terms of any encumbrance or note secured by the Premises. Therefore, if any Rent
or other sum due from Tenant is not received by the end of the 10th day after
due (i.e. by the end of the 10th day of the month for sums due on the first),
Tenant shall pay to Landlord an additional sum equal to 10% of such overdue
payment. Landlord and Tenant hereby agree that such late charge represents a
fair and reasonable estimate of the costs that Landlord will incur by reason of
any such late payment and that the late charge is in addition to any and all
remedies available to the Landlord and that the assessment and/or collection of
the late charge shall not be deemed a waiver of any other default. Additionally,
all such delinquent Rent or other sums, plus this late charge, shall bear
interest at the rate of 12 percent per annum. If the interest rate specified in
this Lease is higher than the rate permitted by law, the interest rate is hereby
decreased to the maximum legal interest rate permitted by law. Any payments of
any kind returned for insufficient funds will be subject to an additional
handling charge of $25.00, and thereafter, Landlord may require Tenant to pay
all future payments of Rent or other sums due by money order or cashier's check.

5.   PREPAID RENT

     Upon the execution of this Lease, Tenant shall, in addition to the payment
of the first month's Rent as set forth in Section 4.a, pay to Landlord the
prepaid Rent set forth in Section l.k, and if Tenant is not in default of any
provisions of this Lease, such prepaid Rent shall be applied toward the Base
Monthly Rent for the months set forth in Section l.k. Landlord's obligations
with respect to the prepaid Rent are those of a debtor and not of a trustee, and
Landlord can commingle the prepaid Rent with Landlord's general funds. Landlord
shall not be required to pay Tenant interest on the prepaid Rent.  Landlord
shall be entitled to immediately endorse and cash Tenant's prepaid Rent;
however, such endorsement and cashing shall not constitute Landlord's 

                                      -8-
<PAGE>
 
acceptance of this Lease. In the event Landlord does not accept this Lease,
Landlord shall return said prepaid Rent.

6.   DEPOSIT

     Upon execution of this Lease, Tenant shall deposit a security deposit and a
cleaning fee as set forth in Section 1.1 with Landlord. If Tenant is in default,
Landlord, upon 5 days notice, can use the security deposit or any portion of it
to cure the default or to compensate Landlord for any damages sustained by
Landlord resulting from Tenant's default. Upon demand, Tenant shall immediately
pay to Landlord a sum equal to the portion of the security deposit expended or
applied by Landlord to restore the security deposit to its full amount. In no
event will Tenant have the right to apply any part of the security deposit to
any Rent or other sums due under this Lease. If Tenant is not in default at the
expiration or termination of this Lease, Landlord shall return the security
deposit to Tenant, and retain the cleaning fee, which shall equal 10% of first
month's Base Monthly Rent or $125, whichever is greater. Landlord's obligations
with respect to the deposit are those of a debtor and not of a trustee, and
Landlord can commingle the security deposit with Landlords general funds.
Landlord shall not be required to pay Tenant interest on the deposit. Upon full
execution of the lease, Landlord shall be entitled to endorse and cash Tenant's
prepaid deposit. Each time the Base Monthly Rent is increased, Tenant shall
deposit additional funds with Landlord sum sufficient to increase the security
deposit to an amount which bears the same relationship to the adjusted Base
Monthly Rent as the initial security deposit bore to the initial Base Monthly
Rent.

7.   USE OF PREMISES AND PROJECT FACILITIES

     Tenant shall use the Premises solely for the purposes set forth in Section
1 and for no other purpose without obtaining the prior written consent of
Landlord. Tenant acknowledges that neither Landlord nor any agent of Landlord
has made any representation or warranty with respect to the Premises or with
respect to the suitability of the Premises or the Project for the conduct of
Tenant's business, nor has Landlord agreed to undertake any modification,
alteration or improvement to the Premises or the Project, except as provided in
writing in this Lease.  Tenant acknowledges that Landlord may from time to time,
at its sole discretion, make such modifications, alterations, deletions or
improvements to the Project as Landlord may deem necessary or desirable, without
compensation or notice to Tenant. Tenant shall promptly comply with all laws,
ordinances, orders and regulations affecting the Premises and the Project,
including, without limitation, any rules and regulations that may be attached to
this Lease and to any reasonable modifications to these rules and regulations as
Landlord may adopt from time to time. Tenant acknowledges that, 

                                      -9-
<PAGE>
 
except for Landlord's obligations pursuant to Section 13, Tenant is solely
responsible for ensuring that the Premises comply with any and all governmental
regulations applicable to Tenant's conduct of business on the Premises, and that
Tenant is solely responsible for any alterations or improvements that may be
required by such regulations, now existing or hereafter adopted. Tenant shall
not do or permit anything to be done in or about the Premises or bring or keep
anything in the Premises that will in any way increase the premiums paid by
Landlord on its insurance related to the Project or which will in any way
increase the premiums for fire or casualty insurance carried by other tenants in
the Project. Tenant will not perform any act or carry on any practices that may
injure the Premises or the Project; that may be a nuisance or menace to other
tenants in the Project; or that shall in any way interfere with the quiet
enjoyment of such other tenants. Tenant shall not use the Premises for sleeping,
washing clothes, cooking or the preparation, manufacture or mixing of anything
that might emit any objectionable odor, noises, vibrations or lights onto such
other tenants. If sound insulation is required to muffle noise produced by
Tenant on the Premises, Tenant at its own cost shall provide all necessary
insulation. Tenant shall not do anything on the premises which will overload any
existing parking or service to the Premises. Pets and/or animals of any type
shall not be kept on the Premises.

existing landscaping, without Landlord's prior written consent, which consent
(in the case of non-structural alternations) shall not be unreasonably withheld.
If Landlord gives its consent to such alterations, Landlord may post notices in
accordance with the laws of the state in which the premises are located. Any
alterations made shall remain on and be surrendered with the Premises upon
expiration or termination of this Lease, except that Landlord may, within 30
days before or 30 days after expiration of the term, elect to require Tenant to
remove any alterations which Tenant may have made to the Premises. If Landlord
so elects, at its own cost Tenant shall restore the Premises to the original
condition, reasonable wear and tear excepted, before the last day of the term or
within 30 days after notice of its election is given, whichever is later.

     Should Landlord consent in writing to Tenant's alteration of the Premises,
Tenant shall contract with a contractor approved by Landlord for the
construction of such alterations, shall secure all appropriate governmental
approvals and permits, and shall complete such alterations with due diligence in
compliance with plans and specifications approved by Landlord. All such
construction shall be performed in a manner which will not interfere with the
quiet enjoyment of other tenants of the Project. Tenant shall pay all costs for
such construction and shall keep the Premises 

                                      -14-
<PAGE>
 
and the Project free and clear of all mechanics' liens which may result from
construction by Tenant.

15.  RELEASE AND INDEMNITY

     A.   TENANT INDEMNITY

     Except as otherwise provided in this Section, Tenant shall indemnify,
defend (using legal counsel acceptable to Landlord) and save Landlord harmless
from all claims, suits, losses, damages, fines, penalties, liabilities and
expenses (including Landlord's personnel and overhead costs and attorneys fees
and other costs incurred in connection with claims, regardless of whether such
claims involve litigation) resulting from any actual or alleged injury
(including death) of any person or from any actual or alleged loss of or damage
to, any property arising out of or in connection with (i)Tenant's occupation,
use or improvement of the Premises, or that of its employees, agents or
contractors, (ii) Tenant's breach of its obligations hereunder, or (iii) any act
or omission of Tenant or any subtenant, licensee, assignee or concessionaire of
Tenant, or of any officer, agent, employee, guest or invitee of Tenant, or of
any such entity in or about the Premises. Tenant agrees that the foregoing
indemnity specifically covers actions brought by its own employees. This
indemnity with respect to acts or omissions during the term of this Lease shall
survive termination or expiration of this Lease. The foregoing indemnity is
specifically and expressly intended to, constitute a waiver of Tenant's immunity
under Washington's Industrial insurance Act, RCW Title 51, to the extent
necessary to provide Landlord with a full and complete indemnity from claims
made by Tenant and its employees, to the extent provided herein. Tenant shall
promptly notify Landlord of casualties or accidents occurring in or about the
Premises.  LANDLORD AND TENANT ACKNOWLEDGE THAT THE INDEMNIFICATION PROVISIONS
OF SECTION 8.F AND THIS SECTION 15 WERE SPECIFICALLY NEGOTIATED AND AGREED UPON
BY THEM.

     B.   LANDLORD INDEMNITY

     Except as otherwise provided in this Section 15, Landlord shall indemnify,
defend (using legal counsel acceptable to Tenant) and save Tenant harmless from
all claims, suits, losses, fines, penalties, liabilities and expenses (including
Tenant's personnel and overhead costs and attorneys' fees and other costs
incurred in connection with claims, regardless of whether such claims involve
litigation) resulting from any actual or alleged injury (including death) of any
person or from any actual or alleged loss of or damage to, any property to the
extent caused by negligent acts of Landlord on the Common Areas. Landlord agrees
that the foregoing indemnity specifically covers actions brought by its own
employees. This indemnity with respect 

                                      -15-
<PAGE>
 
to actions or omissions during the term of this Lease shall survive termination
or expiration of this Lease. The foregoing indemnity is specifically and
expressly intended to constitute a waiver of Landlord's immunity under
Washington's Industrial Insurance Act, RCW Title 51, to the extent necessary to
provide Tenant with a full and complete indemnity from claims made by Landlord
and its employees to the extent provided herein. LANDLORD AND TENANT ACKNOWLEDGE
THAT THE INDEMNIFICATION PROVISIONS OF SECTION 15 WERE SPECIFICALLY NEGOTIATED
AND AGREED UPON BY THEM.

     C.   RELEASE

     Tenant hereby fully and completely waives and releases all claims against
Landlord for any losses or other damages sustained by Tenant or any person
claiming through Tenant resulting from any accident or occurrence in or upon the
Premises, including but not limited to: any defect in or failure of Project
equipment; any failure to make repairs; any defect, failure, surge in, or
interruption of Project facilities or services; any defect in or failure of
Common Areas; broken glass; water leakage; the collapse of any Building
component; or any act, omission or negligence of co-tenants, licensees or any
other persons or occupants of the Building, provided only that the release
contained in this Section 15.c shall not apply to claims for actual damage to
persons or property (excluding consequential damages such as lost profits)
resulting directly from Landlord's gross negligence or willful misconduct or
Landlord's breach of its express obligations under this Lease which Landlord has
not cured within a reasonable time after receipt of written notice of such
breach from Tenant.

     D.   LIMITATION ON INDEMNITY

     In compliance with RCW 4.24.115 as in effect on the date of this Lease, all
provisions of this Lease pursuant to which Landlord or Tenant (the "Indemnitor")
agrees to indemnify the other (the "Indemnitee") against liability for damages
arising out of bodily injury to Persons or damage to property relative to the
construction, alteration, repair, addition to, subtraction from, improvement to,
or maintenance of, any building, road, or other structure, project, development,
or improvement attached to real estate, including the Premises, (i) shall not
apply to damages caused by or resulting from the sole negligence of the
Indemnitee, its agents or employees, and (ii) to the extent caused by or
resulting from the concurrent negligence of (a) the Indemnitee or the
Indemnitee's agents or employees, and (b) the Indemnitor or the Indemnitor's
agents or employees, shall apply only to the extent of the Indemnitor's
negligence; PROVIDED, HOWEVER, the limitations on indemnity set forth in this
Section shall automatically and without further act by either Landlord or Tenant
be 

                                      -16-
<PAGE>
 
deemed amended so as to remove any of the restrictions contained in this Section
no longer required by then applicable law.

     E.   DEFINITIONS

     As used in any Section establishing indemnity or release of Landlord,
"Landlord" shall include Landlord, its partners, officers, employees and
contractors, and "Tenant" shall include Tenant and any person or entity claiming
through Tenant.

16.  INSURANCE

     Tenant, at its cost, shall maintain public liability and property damage
insurance and products liability insurance with a single combined liability
limit of $1,000,000, insuring against all liability of Tenant and its
representatives, employees, invitees, and agents arising out of or in connection
with Tenant's use or occupancy of the Premises. Public liability insurance,
products liability insurance and property damage- insurance shall insure
performance by Tenant of the indemnity provisions of Section 15. Landlord shall
be named as additional insured and the policy shall contain cross-liability
endorsements. On all its personal property, at its cost, Tenant shall maintain a
policy of standard fire and extended coverage insurance with vandalism and
malicious mischief endorsements and "all risk" coverage on all Tenant's
improvements and alterations, including without limitation, all items of Tenant
responsibility described in Section 13 in or about the Premises, to the extent
of at least 90% of their full replacement value. The proceeds from any such
policy shall be used by Tenant for the replacement of personal property and the
restoration of Tenant's improvements or alterations. All insurance required to
be provided by Tenant under this Lease shall release Landlord from any claims
for damage to business or to any person or the Premises and the Project, and to
Tenant's fixtures, personal property, improvements and alterations in or on the
Premises or the Project, caused by or resulting from risks insured against under
any insurance policy carried by Tenant in force at the time of such damage. In
addition, Tenant hereby independently releases Landlord from any and all claims
for damage to business or to any person or the Premises and the Project, and to
Tenant's fixtures, personal property, improvements and alterations in or on the
Premises or the Project, caused by or resulting from risks that would have been
insured against under any insurance policy required by this Lease to be carried
by Tenant, even if Tenant failed to so carry the required insurance. All
insurance required to be provided by Tenant under this Lease: (a) shall be
issued by Insurance companies authorized to do business in the state in which
the premises are located with a financial rating of at least an A+XII status as
rated in the most recent edition of Best's Insurance Reports; (b) shall be
issued as a primary policy; and (c) shall contain an endorsement requiring at
least 30 days prior written notice of 

                                      -17-
<PAGE>
 
cancellation to Landlord and Landlord's lender, before cancellation or change in
coverage, scope or amount of any policy. Tenant shall deliver a certificate or
copy of such policy together with evidence of payment of all current premiums to
Landlord within 30 days of execution of this Lease. If Tenant fails at any time
to maintain the insurance required by this Lease, and fails to cure such default
within five (5) business days of written notice from Landlord then, in addition
to all other remedies available under this Lease and applicable law, Landlord
may purchase such insurance on Tenant's behalf and the cost of such insurance
shall be Additional Rent due within ten (10) days of written invoice from
Landlord to Tenant.

17.  DESTRUCTION

     If during the term, the Premises or Project are more than 10% destroyed
from any cause, or rendered inaccessible or unusable from any cause, Landlord
may, in its sole discretion, terminate this Lease by delivery of notice to
Tenant within 30 days of such event without compensation to Tenant. If in
Landlord's estimation, the Premises cannot be restored within 90 days following
such destruction, the Landlord shall notify Tenant and Tenant may terminate this
Lease by delivery of notice to Landlord within 30 days of receipt of Landlord's
notice. If neither Landlord nor Tenant terminates this Lease as provided above,
then Landlord shall commence to restore the Premises in compliance with then
existing laws and shall complete such restoration with due diligence. In such
event, this Lease shall remain in full force and effect, but there shall be an
abatement of Base Monthly Rent and Tenant's Share of Expenses between the date
of destruction and the date of completion of restoration, based on the extent to
which destruction interferes with Tenant's use of the Premises.

18.  CONDEMNATION

     A.   TAKING

     If all of the Premises are taken by Eminent Domain, this Lease shall
terminate as of the date Tenant is required to vacate the Premises and all Base
and Additional Rent shall be paid to that date. The term "Eminent Domain" shall
include the taking or damaging of property by, through or under any governmental
or statutory authority, and any purchase or acquisition in lieu thereof, whether
the damaging or taking is by government or any other person. If, in the
reasonable judgment of Landlord, a taking of any part of the Premises by Eminent
Domain renders the remainder thereof unusable for the business of Tenant (or the
cost of restoration of the Premises is not commercially reasonable), the Lease
may, at the option of either party, be terminated by written notice given to the
other party not more than thirty (30) days after Landlord gives Tenant written
notice of the taking, and such termination shall be effective as of the date
when Tenant is required to vacate the portion of the Premises so taken. If this

                                      -18-
<PAGE>
 
Lease is so terminated, all Base and Additional Rent shall be paid to the date
of termination. Whenever any portion of the Premises is taken by Eminent Domain
and this Lease is not terminated, Landlord shall at its expense proceed with all
reasonable dispatch to restore, to the extent of available proceeds and to the
extent it is reasonably prudent to do so, the remainder of the Premises to the
condition they were in immediately prior to such taking, and Tenant shall at its
expense proceed with all reasonable dispatch to restore its personal property
and all improvements made by it to the Premises to the same condition they were
in immediately prior to such taking. The Base and Additional Rent payable
hereunder shall be reduced from the date Tenant is required to partially vacate
the Premises in the same proportion that the Rentable Area taken bears to the
total Rentable Area of the Premises prior to taking.

     B.   AWARD

     Landlord reserves all right to the entire damage award or payment for any
taking by Eminent Domain, and Tenant waives all claim whatsoever against
Landlord for damages for termination of its leasehold interest in the Premises
or for interference with its business. Tenant hereby grants and assigns to
Landlord any right Tenant may now have or hereafter acquire to such damages and
agrees to execute and deliver such further instruments of assignment as Landlord
may from time to time request. Tenant shall, however, have the right to claim
from the condemning authority all compensation that may be recoverable by Tenant
on account of any loss incurred by Tenant in moving Tenant's merchandise,
furniture, trade fixtures and equipment, provided, however that Tenant may claim
such damages only if they are awarded separately in the eminent domain
proceeding and not out of or as part of Landlord's damages.

19.  ASSIGNMENT OR SUBLEASE

     Tenant shall not assign or encumber its interest in this Lease or the
Premises or sublease all or any part of the Premises or allow any other person
or entity (except Tenant's authorized representatives, employees, invitees, or
guests) to occupy or use all or any part of the Premises without first obtaining
Landlord's consent which Landlord may withhold or condition in its sole
discretion, provided only that (a) Landlord shall consent to a merger or
combination and associated assignment or sublease for the same use where (I) the
succeeding entity has a net worth equal to or greater than that of Tenant
immediately prior to the assignment or sublease and (ii) Tenant's management
team is a substantial part of the management team of the successor entity and
(b) Landlord shall consent to a sublease for the same use to a subtenant of
equal or greater financial strength from Tenant.  No assignment or sublease
shall release Tenant from the obligation to perform all obligations under this

                                      -19-
<PAGE>
 
Lease. Any assignment, encumbrance or sublease without Landlord's written
consent shall be voidable and at Landlord's election, shall constitute a
default. If Tenant is a partnership, a withdrawal or change, voluntary,
involuntary or by operation of law of any partner, or the dissolution of the
partnership, shall be deemed a voluntary assignment. If Tenant consists of more
than one person, a purported assignment, voluntary or involuntary or by
operation of law from one person to the other shall be deemed a voluntary
assignment. If Tenant is a corporation, any dissolution, merger, consolidation
or other reorganization of Tenant, or sale or other transfer of a controlling
percentage of the capital stock of Tenant, or the sale of at least 25% of the
value of the assets of Tenant shall be deemed a voluntary assignment. The phrase
"controlling percentage" means ownership of and right to vote stock possessing
at least 25% of the total combined voting power of all classes of Tenant's
capital stock issued, outstanding and entitled to vote for election of
directors. This Section 19 shall not apply to corporations the stock of which is
traded through an exchange or over the counter. All rent received by Tenant from
its subtenants in excess of the Rent payable by Tenant to Landlord under this
Lease shall be paid to Landlord, or any sums to be paid by an assignee to Tenant
in consideration of the assignment of this Lease shall be paid to Landlord. If
Tenant requests Landlord to consent to a proposed assignment or subletting,
Tenant shall pay to Landlord, whether or not consent is ultimately given, $100
or Landlord's reasonable attorney's fees incurred in connection with such
request, whichever is greater, not to exceed $250 per transaction.

     No interest of Tenant in this Lease shall be assignable by involuntary
assignment through operation of law (including without limitation the transfer
of this Lease by testacy or intestacy). Each of the following acts shall be
considered an involuntary assignment: (a) if Tenant is or becomes bankrupt or
insolvent, makes an assignment for the benefit of creditors, or institutes
proceedings under the Bankruptcy Act in which Tenant is the bankrupt; or if
Tenant is a partnership or consists of more than one person or entity, if any
partner of the partnership or other person or entity is or becomes bankrupt or
insolvent, or makes an assignment for the benefit of creditors; or (b) if a writ
of attachment or execution is levied on this Lease; or (c) if in any proceeding
or action to which Tenant is a party, a receiver is appointed with authority to
take possession of the Premises. An involuntary assignment shall constitute a
default by Tenant and Landlord shall have the right to elect to terminate this
Lease, in which case this Lease shall not be treated as an asset of Tenant.

20.  DEFAULT

     The occurrence of any of the following shall constitute a default by
Tenant: (a) a failure to pay Rent or other charge when due provided that
Landlord shall not exercise any of its rights under this Section 20 until
Landlord has given Tenant notice 

                                      -20-
<PAGE>
 
of such default and Tenant has failed to pay such rent or other charge within
three (3) days of the effective date of such notice; (b) abandonment and
vacation of the Premises (failure to occupy and operate the Premises for ten
consecutive days shall be conclusively deemed an abandonment and vacation); or
(c) failure to perform any other provision of this Lease, provided that Landlord
shall not exercise any of its rights under this Section 20(c) until Landlord has
given Tenant notice of such default and Tenant has failed to cure such default
and provided further that if more than thirty (30) days are required to complete
such performance, Landlord shall not exercise any of its rights if Tenant
commences to cure such default within the thirty (30) day period and thereafter
diligently pursues such cure completion. The notice required by this Section is
intended to satisfy any and all notice requirements imposed by law on Landlord
and is not in addition to any such requirement.

21.  LANDLORD'S REMEDIES

     Landlord shall have the following remedies if Tenant is in default and has
failed to cure such default within any applicable cure period. (These remedies
are not exclusive; they are cumulative and in addition to any remedies now or
later allowed by law): Landlord may terminate Tenant's right to possession of
the Premises at any time. No act by Landlord other than giving notice to Tenant
shall terminate this Lease. Acts of maintenance, efforts to relet the Premises,
or the appointment of a receiver on Landlord's initiative to protect Landlord's
interest under this Lease shall not constitute a termination of Tenant's right
to possession. Upon termination of Tenant's right to possession, Landlord has
the right to recover from Tenant: (1) the worth of the unpaid Rent that had been
earned at the time of termination of Tenant's right to possession; (2) the worth
of the amount of the unpaid Rent that would have been earned after the date of
termination of Tenant's right to possession; (3) any other amount, including but
not limited to, expenses incurred to relet the Premises, court, attorney and
collection costs, necessary to compensate Landlord for all detriment caused by
Tenant's default. "The Worth," as used for Item (1) in this Paragraph 21 is to
be computed by allowing interest at the rate of 12 percent per annum. If the
interest rate specified in this Lease is higher than the rate permitted by law,
the interest rate is hereby decreased to the maximum legal interest rate
permitted by law. "The Worth" as used for Item (2) in this Paragraph 21 is to be
computed by discounting the amount at the discount rate of the Federal Reserve
Bank of San Francisco at the time of termination of Tenant's right of
possession.

22.  ENTRY ON PREMISES

     Landlord and its authorized representatives shall have the right to enter
the Premises at all reasonable times and upon reasonable notice except in an
emergency, 

                                      -21-
<PAGE>
 
when no notice shall be required, for any of the following purposes:
(a) to determine whether the Premises are in good condition and whether Tenant
is complying with its obligations under this Lease; (b) to do any necessary
maintenance and to make any restoration to the Premises or the Project that
Landlord has the right or obligation to perform; (c) to post "for sale" signs at
any time during the term, to post "for rent" or "for lease" signs during the
last 90 days of the teem, or during any period while Tenant is in default; (d)
to show the Premises to prospective brokers, agents, buyers, tenants or persons
interested in leasing or purchasing the Premises, at any time during the term;
or (e) to repair, maintain or improve the Project and to erect scaffolding and
protective barricades around and about the Premises but not so as to prevent
entry to the Premises and to do any other act or thing necessary for the safety
or preservation of the Premises or the Project. Landlord shall not be liable in
any manner for any inconvenience, disturbance, loss of business, nuisance or
other damage arising out of Landlord's entry onto the Premises as provided in
this Section 22. Tenant shall not be entitled to an abatement or reduction of
Rent if Landlord exercises any rights reserved in this Section 22. Landlord
shall conduct his activities on the Premises as provided herein in a
commercially reasonable manner so as to limit inconvenience, annoyance or
disturbance to Tenant to the maximum extent practicable. For each of these
purposes, Landlord shall at all times have and retain a key with which to unlock
all the doors in, upon and about the Premises, excluding Tenant's vaults and
safes. Tenant shall not alter any lock or install a new or additional lock or
bolt on any door of the Premises without prior written consent of Landlord. If
Landlord gives its consent, Tenant shall furnish Landlord with a key for any
such lock.

23.  SUBORDINATION

     Without the necessity of any additional document being executed by Tenant
for the purpose of effecting a subordination, and at the election of Landlord or
any mortgagee or any beneficiary of a Deed of Trust with a lien on the Project
or any ground lessor with respect to the Project, this Lease shall be subject
and subordinate at all times to (a) all ground leases or underlying leases which
may now exist or hereafter be executed affecting the Project, and (b) the lien
of any mortgage or deed of trust which may now exist or hereafter be executed in
any amount for which the Project, ground leases or underlying leases, or
Landlord's interest or estate in any of said items is specified as security. In
the event that any ground lease or underlying lease terminates for any reason or
any mortgage or Deed of Trust is foreclosed or a conveyance in lieu of
foreclosure is made for any reason, Tenant shall, notwithstanding any
subordination, attorn to and become the Tenant of the successor in interest to
Landlord, at the option of such successor in interest. Tenant covenants and
agrees to execute and deliver, upon demand by Landlord and in the form requested
by Landlord any additional documents evidencing the priority or 

                                      -22-
<PAGE>
 
subordination of this Lease with respect to any such ground lease or underlying
leases or the lien of any such mortgage or Deed of Trust. Tenant hereby
irrevocably appoints Landlord as attorney-in-fact of Tenant to execute, deliver
and record any such document in the name and on behalf of Tenant.

     Tenant, within ten days from notice from Landlord, shall execute and
deliver to Landlord, in recordable form, certificates stating that this Lease is
not in default, is unmodified and in full force and effect, or in full force and
effect as modified, and stating the modifications. This certificate should also
state the amount of current monthly Rent, the dates to which Rent has been paid
in advance, and the amount of any security deposit and prepaid Rent. Failure to
deliver this certificate to Landlord within ten days shall be conclusive upon
Tenant that this Lease is in full force and effect and has not been modified
except as may be represented by Landlord.

24.  NOTICE

     Any notice, demand or request required hereunder shall be given in writing
to the party's facsimile number or address set forth in Section 1 hereof by any
of the following means: (a) personal service; (b) electronic communication,
whether by telex, telegram or facsimile; (c) overnight courier; or (d)
registered or certified, first class mail, return receipt requested. Such
addresses may be changed by notice to the other parties given in the same manner
as above provided. Any notice, demand or request sent pursuant to either
subsection (a) or (b) hereof shall be deemed received upon such personal service
or upon dispatch by electronic means with electronic confirmation of receipt.
Any notice, demand or request sent pursuant to subsection (c) hereof shall be
deemed received on the business day immediately following deposit with the
overnight courier and, if sent pursuant to subsection (d), shall be deemed
received forty-eight (48) hours following deposit in the U.S. mail.

25.  WAIVER

     No delay or omission in the exercise of any right or remedy by Landlord
shall impair such right or remedy or be construed as a waiver. No act or conduct
of Landlord, including without limitation, acceptance of the keys to the
Premises, shall constitute an acceptance of the surrender of the Premises by
Tenant before the expiration of the term. Only written notice from Landlord to
Tenant shall constitute acceptance of the surrender of the Premises and
accomplish termination of the Lease. Landlord's consent to or approval of any
act by Tenant requiring Landlord's consent or approval shall not be deemed to
waive or render unnecessary Landlord's consent to or approval of any subsequent
act by Tenant. Any waiver by Landlord of any default must be in writing and
shall not be a waiver of any other default concerning the same or any other
provision of the Lease. TENANT SPECIFICALLY ACKNOWLEDGES 

                                      -23-
<PAGE>
 
AND AGREES THAT, WHERE TENANT HAS RECEIVED A NOTICE TO CURE DEFAULT (WHETHER
RENT OR NON-RENT), NO ACCEPTANCE BY LANDLORD OF RENT SHALL BE DEEMED A WAIVER OF
SUCH NOTICE, AND, INCLUDING BUT WITHOUT LIMITATION, NO ACCEPTANCE BY LANDLORD OF
PARTIAL RENT SHALL BE DEEMED TO WAIVE OR CURE ANY RENT DEFAULT. LANDLORD MAY, IN
ITS DISCRETION, AFTER RECEIPT OF PARTIAL PAYMENT OF RENT, REFUND SAME AND
CONTINUE ANY PENDING ACTION TO COLLECT THE FULL AMOUNT DUE, OR MAY MODIFY ITS
DEMAND TO THE UNPAID PORTION. IN EITHER EVENT THE DEFAULT SHALL BE DEEMED
UNCURED UNTIL THE FULL AMOUNT IS PAID IN GOOD FUNDS.

26.  SURRENDER OF PREMISES; HOLDING OVER

     Upon expiration of the term, Tenant shall surrender to Landlord the
Premises and all Tenant improvements and alterations in good condition, except
for ordinary wear and tear and alterations Tenant has the right or is obligated
to remove under the provisions of Section 14 herein. Tenant shall remove all
personal property including, without limitation, all wallpaper, paneling and
other decorative improvements or fixtures and shall perform all restoration made
necessary by the removal of any alterations or Tenant's personal property before
the expiration of the term, including for example, restoring all wall surfaces
to their condition prior to the commencement of this Lease. Landlord can elect
to retain or dispose of in any manner Tenant's personal property not removed
from the Premises by Tenant prior to the expiration of the term. Tenant waives
all claims against Landlord for any damage to Tenant resulting from Landlord's
retention or disposition of Tenant's personal property. Tenant shall be liable
to Landlord for Landlord's cost for storage, removal or disposal of Tenant's
personal property.

     If Tenant, with Landlord's consent, remains in possession of the Premises
after expiration or termination of the term, or after the date in any notice
given by Landlord to Tenant terminating this Lease, such possession by Tenant
shall be deemed to be a month-to-month tenancy terminable as provided under
Washington law, by either party. All provisions of this Lease, except those
pertaining to term and Rent, shall apply to the month-to-month tenancy. During
any holdover term, Tenant shall pay Base Monthly Rent in an amount equal to 125%
of Base Monthly Rent for the last full calendar month during the regular term
plus 100% of Tenant's share of Expenses pursuant to Section 4.c.3.

                                      -24-
<PAGE>
 
27.  BUILDING PLANNING

     If Landlord requires the Premises for use in conjunction with another suite
or for other reasons connected with the Project planning program, upon notifying
Tenant in writing, Landlord shall have the right to move Tenant to other space
in the Project that is substantially the same in size, configuration and tenant
improvements, such move (including out-of-pocket ancillary costs such as
reprinting of stationary) to be at Landlord's sole cost and expense. Upon such
move, the terms and conditions of the original Lease shall remain in full force
and effect, save and excepting that a revised Exhibit "A" shall become part of
this Lease and shall reflect the location of the new space and Section 1 of this
Lease shall be amended to include and state all correct data as to the new
space. Notwithstanding the above, if Landlord notifies Tenant of Landlord's
intention to exercise the relocation rights provided in this Section 27, Tenant
may, within 30 days of receipt of such notice, notify Landlord of Tenant's
intention to terminate this Lease. If Tenant so notifies Landlord, then either
(i) Landlord shall, within 30 days of receipt of Tenant's notice, rescind the
relocation notice and this Lease shall continue unaltered, or (ii) this Lease
shall terminate 90 days following Landlord's receipt of Tenant's notice without
any liability to Landlord or Tenant for such early termination.

28.  MISCELLANEOUS PROVISIONS

     28.1   TIME OF ESSENCE

     Time is of the essence of each provision of this Lease.

     28.2   SUCCESSOR

     This Lease shall be binding on and inure to the benefit of the parties and
their successors, except as provided in Section 19 herein.

     28.3.  LANDLORD'S CONSENT

     Except as otherwise specifically provided, any consent required by Landlord
under this Lease must be granted in writing and may be withheld or conditioned
by Landlord in its sole and absolute discretion.

     28.4   COMMISSIONS

     Each party represents that it has not had dealings with any real estate
broker, finder or other person with respect to this Lease in any manner, except
for the broker identified in Section 1, who shall be compensated by Landlord.
Landlord and Tenant recognize that it is possible that they may hereafter make
additional agreements 

                                      -25-
<PAGE>
 
regarding further extension or renewal of this Lease or a new lease or leases
for all or one or more parts of the Premises or other space in the Project for a
term or terms commencing after the Commencement Date of this Lease. Landlord and
Tenant recognize that it is also possible that they may hereafter modify this
Lease to add additional space or to substitute space as part of the Premises. If
any such additional agreements, new leases or modifications to this Lease are
made, Landlord shall not have any obligation to pay any compensation to any real
estate broker or to any other third person engaged by Tenant to render services
to Tenant in connection with negotiating such matters, regardless of whether
under the circumstances such person is or is not regarded by the law as an agent
of Landlord.

     28.5 OTHER CHARGES

     If either party commences any litigation against the other party or files
an appeal of a decision arising out of or in connection with the Lease, the
prevailing party shall be entitled to recover from the other party reasonable
attorney's fees and costs of suit. If Landlord employs a collection agency to
recover delinquent charges, Tenant agrees to pay all collection agency and
attorneys' fees charged to Landlord in addition to Rent, late charges, interest
and other sums payable under this Lease. Tenant shall pay a charge of $75 to
Landlord for preparation of a demand for delinquent Rent.

     28.6 FORCE MAJEURE

     Landlord shall not be deemed in default hereof nor liable for damages
arising from its failure to perform its duties or obligations hereunder if such
is due to causes beyond its reasonable control, including, but not limited to,
acts of God, acts of civil or military authorities, fires, floods, windstorms,
earthquakes, strikes or labor disturbances, civil commotion, delays in
transportation, governmental delays or war.

     28.7 RULES AND REGULATIONS

     Tenant shall faithfully observe and comply with the "Rules and
Regulations", a copy of which is attached hereto, and all reasonable and
nondiscriminatory modifications thereof and additions thereto from time to time
put into effect by Landlord. Landlord shall not be responsible to Tenant for the
violation or non-performance by any other tenant or occupant of the building or
Project of said tenant or occupant's lease or of any of said Rules and
Regulations.

     28.8   LANDLORD'S SUCCESSORS

     In the event of a sale or conveyance by Landlord of the Project, the same
shall operate to release Landlord from any liability under this Lease, and in
such event Landlord's successor in interest shall be solely responsible for all
obligations of Landlord under this Lease.

     28.9   INTERPRETATION

     This Lease shall be construed and interpreted in accordance with the laws
of the state in which premises are located. This Lease constitutes the entire
agreement between the parties with respect to the Premises and the Project,
except for such guarantees or modifications as may be executed in writing by the
parties from time to time. When required by the context of this Lease, the
singular shall include the plural, and the masculine shall include the feminine
and/or neuter. "Party" shall mean Landlord or Tenant. If more than one person or
entity constitutes Landlord or Tenant, the obligations imposed upon that party
shall be joint and several. The enforceability, invalidity or illegality of any
provision shall not render the other provisions unenforceable, invalid or
illegal.

     28.10  CLEAN AIR ACT

     Tenant acknowledges that Landlord has not made any portion of the Premises
or the Building accessible for smoking in compliance with WAC 296-62-12000. If
Tenant wishes to make any portion of the Premises accessible for smoking, Tenant
shall make all improvements necessary to comply with all applicable governmental
rules and regulations. Tenant acknowledges that the indemnity contained in
Section 15 of the Lease includes, but is not limited to claims based on the
presence of tobacco smoke as a result of the activities of Tenant, its
employees, agents, or guests.

29.  TENANT IMPROVEMENTS

     Tenant may undertake the removal of one office and one wall in the
Premises, as well as any required touch-up painting and carpet patching. Tenant
may also install telephones, furniture, telecommunications cables and other
equipment in the Premises as reasonably needed for the operation of its business
activities. All such improvements, alterations and additions (other than
Tenant's trade fixtures, furniture and equipment) shall become the property of
the Landlord and shall remain in and be surrendered with the Premises at the
termination of this Lease.

     All improvements, alterations and additions undertaken by Tenant shall be
performed by a contractor approved to do work in the Project. Tenant shall cause
all 

                                      -27-
<PAGE>
 
work to be done in a good and workmanlike manner using materials equal to or
better than those used in the construction of the Premises. During construction,
Tenant or its general contractor shall procure and maintain in effect all
insurance coverages required under this Lease and any additional insurance
coverage reasonably required by Landlord and customary for similar tenant
improvement projects.

     Landlord agrees to reimburse Tenant for up to $5,000 for actual amounts
paid to third parties for work done as described in this paragraph. Landlord
will, within 30 from receipt of receipts for such work done, reimburse Tenant
for these charges.

30.  CARDKEY SYSTEM

     Tenant shall be allowed to install a card access entry pad on the exterior
of the main entrance to the Premises, so as to work in conjunction with its
existing card key system in the Project.  At the expiration of the Lease, Tenant
at its own cost shall remove such card access entry pad and repair any damage
resulting therefrom.

2.   PREMISES

     Landlord leases to Tenant the premises described in Section 1 and in
Exhibit A, (the "Premises") and Exhibit A-1 ("Expansion Space"), located in this
project described on Exhibit B and Exhibit B-1 (the "Projects"). Landlord
reserves the right to modify Tenant's percentage of the Project as set forth in
Section 1 if the Project size is 
<PAGE>
 
increased through the development of additional property. By entry on the
Premises, Tenant acknowledges that it has examined the Premises and accepts the
Premises in their present condition, subject to any additional work Landlord has
agreed to do.

14.  ALTERATIONS

     Tenant shall not make any alterations to the Premises, or to the Project,
including any changes to the existing landscaping, without Landlord's prior
written consent, which consent (in the case of non-structural alterations) shall
not be unreasonably withheld. If Landlord gives its consent to such alterations,
Landlord may post notices in accordance with the laws of the state in which the
Premises are located. The parties acknowledge that Tenant is considering making
specific alterations to the Expansion Space which will include eliminating an
existing conference room and existing cabinets and which will also require
alterations to existing carpet (collectively, the "Possible Alterations"). If
Landlord approves and Tenant completes the Possible Alterations, upon expiration
or termination of this Lease, Tenant shall deposit with Landlord the amount
necessary, as determined by Landlord (the "Completion Deposit"), to complete the
following: (i) construct a conference room with dimensions of at least 16' x 12'
in approximately the same location as the existing conference room which will be
eliminated as part of the Possible Alterations, using then-existing standard
Project finishes; and (ii) to construct and install, in a location determined by
Landlord, a minimum of eight (8) lineal feet of upper and lower cabinets, using
then-existing Project standard finishes. Further, if Landlord approves and
Tenant completes the Possible Alterations, upon expiration or termination of
this Lease, Landlord shall be authorized to apply up to sixty percent (60%) of
the Security Deposit for replacement of the carpet (standard Project grade)
throughout the office portion of the Expansion Space. Tenant shall not owe the
Completion Deposit and Landlord shall not be entitled to apply the 60% portion
of the Security Deposit as provided herein if termination or expiration of the
Lease occurs after June 30, 1999. Any alterations made shall remain on and be
surrendered with the Premises except that Landlord may, within 30 days before or
30 days after expiration of the term, elect to require Tenant to remove any
alterations which Tenant may have made to the Premises, other than the Possible
Alterations. If Landlord so elects, at its own cost Tenant shall restore the
Premises to the original condition, reasonable wear and tear excepted, before
the last day of the term or within 30 days after notice of its election is
given, whichever is later. Tenant may, at the time of requesting Landlord's
consent to alterations, further request in writing that Landlord elect, at the
time of granting consent, whether such alterations must be removed upon
termination of the lease.

     Should Landlord consent in writing to Tenant's alteration of the Premises,
Tenant shall contract with a contractor approved by Landlord for the
construction of

                                      -2-
<PAGE>
 
such alterations, shall secure all appropriate governmental approvals and
permits, and shall complete such alterations with due diligence in compliance
with plans and specifications approved by Landlord. All such construction shall
be performed in a manner which will not interfere with the quiet enjoyment of
other tenants of the Project. Tenant shall pay all costs for such construction
and shall keep the Premises and the Project free and clear of all mechanics'
liens which may result from construction by Tenant.

31.  EARLY OCCUPANCY

     Tenant shall be entitled to occupy the Premises for the purpose of
construction of Tenant Improvements. If Tenant so occupies the Premises prior to
the Commencement Duty then (i) all provisions of this Lease other than payment
of Base Monthly Rent and Tenant's Share of Expenses shall be applicable from and
after the date of Tenant's first occupancy, and (ii) Tenant shall pay Landlord,
within fifteen (15) days of invoice, the cost of utility services used during
construction as reasonably estimated by Landlord. If Tenant commences to do
business at or from the Premsies prior to April 7, 1997, then Section 1 (g)
shall be deemed amended to establish as the Commencement Date the day on which
Tenant commenced to do business at or from the Premises.

     All other terms and conditions of the above described Lease shall remain in
full force and effect.

2.          PREMISES/COMMON AREAS/PROJECT.

     A.     PREMISES

     Landlord leases to Tenant the premises described in Section 1 and in
Exhibit A (the "Premises") and Exhibit A-1 (the "Expansion Space"), located in
this project described on Exhibit B (the "Project").  By entry on the Premises,
Tenant acknowledges that it has examined the Premises and accepts the Premises
in their present condition, subject to any additional work Landlord has agreed
to do.  Tenant represents and warrants that it agrees with the square footage
specified for the Premises and the Project in Section 1 and will not hereafter
challenge such    determination and agreement.

     B.     COMMON AREAS

     As used in this Lease, "Common Areas" shall mean all portions of the
Project not leased or demised for lease to specific tenants.  During the Lease
Term, Tenant and its licensees, invitees, customers and employees shall have the
non-exclusive right to use the public portions of the Common Areas, including
all parking areas,

                                                                       PAGE 2
<PAGE>
 
landscaped areas, entrances, lobbies, elevators, stairs, corridors, and public
restrooms in common with Landlord, other Project tenants and their respective
licensees, invitees, customers and employees. Landlord shall at all times have
exclusive control and management of the Common Areas and no diminution thereof
shall be deemed a constructive or actual eviction or entitle Tenant to
compensation or a reduction or abatement of rent. Landlord in its discretion may
increase, decrease or change the number, locations and dimensions of any Common
Areas and other improvements shown on Exhibit A which are not within the
Premises, provided only that (subject to temporary construction inconveniences)
no decrease or rearrangement may materially disrupt the use or access to the
Premises or materially decrease the availability of parking.

     C.     PROJECT

     Landlord reserves the right in its sole discretion to modify or alter the
configuration or number of buildings in the Project, provided only that upon
such modification or alteration, the Project Area as set forth in Section l(f)
shall be adjusted to reflect such modification or alteration.

3.          TERM

     The Commencement Date listed in Section 1 of this Lease represents an
estimate of the Commencement Date.  This Lease shall commence on the estimated
Commencement Date if tenant improvement work required of Landlord pursuant to
this Lease ("Landlord's Work") is substantially completed (as that term is used
in the construction industry) by such date, but otherwise the Commencement Date
shall be first to occur of the following events (i) the date on which Landlord
notifies Tenant that Landlord's Work is substantially complete, (ii) the date on
which Tenant takes possession or commences beneficial occupancy of the Premises,
or (iii) if substantial completion of Landlord's Work is delayed due to Tenant's
failure to perform its obligations under this Lease, then the date determined by
Landlord as the date upon which Landlord's Work would have been substantially
completed, but for Tenant's failure to perform.  If this Commencement Date is
later than the Section 1 Commencement Date, this Lease shall not be void or
voidable, nor shall Landlord be liable to Tenant for any loss or damage
resulting therefrom.  Notwithstanding the foregoing, if Tenant is not permitted
access to use the Premises for the purposes described in Section 1(d) within
thirty (30) days of the Commencement Date, this Lease shall be voidable at the
discretion of the Tenant by notice given by Tenant to Landlord within three (3)
days after expiration of such thirty (30) day period.  Landlord shall confirm
the Commencement Date by written notice to Tenant.  This Lease shall be for a
term ("Lease Term") beginning on the Commencement Date and ending on the
Expiration Date, unless extended or sooner terminated in accordance

                                                                       PAGE 3
<PAGE>
 
with the terms of this Lease. All provisions of this Lease, other than those
relating to payment of Base Monthly Rent and Additional Rent, shall become
effective upon the first to occur of (a) the date that Tenant or its officers,
agents, employees or contractors is first present on the Premises, whether for
inspection, construction, installation or other purposes, or (b) such other
date, if any, as may be specified in an Exhibit hereto.

4.          RENT

     A.     BASE RENT

     Tenant shall pay Landlord monthly base rent in the initial amount in
Section 1 which shall be payable monthly in advance on the first day of each and
every calendar month ("Base Monthly Rent") provided, however, the first month's
Base Monthly Rent and Tenant's Share of Expenses is due and payable upon
execution of this Lease.  If the term of this Lease contains any rental
abatement period, Tenant hereby agrees that if Tenant breaches the Lease and
fails to cure such breach within the applicable cure period, if any, and/or
abandons the Premises before the end of the Lease term, or if Tenant's right to
possession is terminated by Landlord because of Tenant's breach of the Lease,
the rental abatement period shall be deemed extinguished, and there shall be
immediately due from Tenant to Landlord, in addition to any damages otherwise
due Landlord under the terms and conditions of the Lease, Base Monthly Rent
prorated for the entirety of the rental abatement period at the average Base
Monthly Rent for the Lease, plus any and all other charges (such as Expenses)
that were abated during such rental abatement period.

     For purposes of Section 467 of the Internal Revenue Code, the parties to
this Lease hereby agree to allocate the stated Rents, provided herein, to the
periods which correspond to the actual Rent payments as provided under the terms
and conditions of this agreement.

     B.     RENT ADJUSTMENT

            1)  COST OF LIVING ADJUSTMENT

     If Section i.i(1) is initialed, the Base Monthly Rent shall be subject to
increase on each annual anniversary of the first day of the first full calendar
month after the Commencement Date (the "Anniversary Date").  The base for
computing the increase is the Consumer Price Index All Urban Consumers U.S. City
Average (1982-84=100), published by the United States Department of Labor,
Bureau of Labor Statistics ("Index"), which is in effect on the ninetieth (90th)
day preceding the Commencement Date ("Beginning Index").  The Index published
and in effect on the ninetieth (90th) day preceding each Anniversary Date
("Extension Index") is to be used in determining

                                                                       PAGE 4
<PAGE>
 
the amount of the increase from one year to the next. Beginning with the Rent
due on and after the first anniversary the Base Monthly Rent shall be increased
to equal the product achieved by multiplying the full Base Monthly Rent due with
respect to the month immediately preceding such anniversary date by a fraction.
On the first Anniversary Date, the numerator of the fraction will be the
Extension Index and the denominator will be the Beginning Index. On the second
and any subsequent Anniversary Date, the numerator of the fraction will be the
current Extension Index and the denominator will be the Extension Index used to
calculate the previous year's Base Monthly Rental increase. If there is a
decline from one lease year to the next in the Extension Index, the Base Monthly
Rent due during the subsequent lease year shall equal the Base Monthly Rent due
during the then present lease year.

     If the Index is changed so that the base year differs from that in effect
when the term commences, the Index shall be converted in accordance with the
conversion factor published by the United States Department of Labor, Bureau of
Labor Statistics.  If the Index is discontinued or revised during the term, such
other government index or computation with which it is replaced shall be used in
order to obtain substantially the same result as would be obtained if the Index
had not been discontinued or revised.

            2)  STEP INCREASE

     If Section 1.i.(2) is initialed, Base Monthly Rent shall be increased
periodically to the amounts and at the times set forth in Section 1.i.(2).

     C.     EXPENSES

     The purpose of this Section 4.c is to ensure that Tenant bears a share of
all Expenses related to the use, maintenance, ownership, repair or replacement,
and insurance of the Project.  Accordingly, beginning on January l, 1999, Tenant
shall each month pay to Landlord one-twelfth (1/12) of Tenant's Share of
Expenses related to the Project.  As used in this Lease, "Tenant's Share" shall
mean the Premises Area, as defined in Section 1.e, divided by the Project Area,
as defined in Section 1.f, and "Tenant's Share of Expenses" shall mean total
Expenses for the Project, multiplied by Tenant's Share, minus the Annual Expense
Base set forth in Section 1(j).  Landlord may specially allocate individual
expenses where and in the manner necessary, in Landlord's discretion, to
appropriately reflect the consumption of the expense or service.  For example
where some but not all premises in the Project have HVAC, Landlord may
reallocate Project Expenses for HVAC to all premises utilizing HVAC to be
apportioned on a per square foot basis, or could allocate to each premises
utilizing HVAC the cost of maintaining that space's individual unit.  In the
event the average occupancy level of the Project for any year is less than
ninety five percent

                                                                       PAGE 5
<PAGE>
 
(95%), the actual Expenses for such year shall be proportionately adjusted to
reflect those costs which Landlord estimates would have been incurred, had the
Project been ninety five percent (95%) occupied during such year.

            1)  EXPENSES DEFINED

     The term "Expenses" shall mean all costs and expenses of the ownership,
operation, maintenance, repair or replacement, and insurance of the Project,
including without limitation, the following costs:

          (a) All supplies, materials, labor, equipment, and utilities used in
or related to the operation and maintenance of the Project,

          (b) All maintenance, management, janitorial, legal, accounting,
insurance, and service agreement costs related to the Project;

          (c) All maintenance, replacement and repair costs relating to the
areas within or around the Project, including, without limitation, air
conditioning systems, sidewalks, landscaping, service areas, driveways, parking
Areas (including resurfacing and restriping parking areas), walkways, building
exteriors (including painting), signs and directories, repairing and replacing
roofs, walls, etc.  These costs may be included either based on actual
expenditures or the use of an accounting reserve based on past cost experience
for the Project.

          (d) Amortization (along with reasonable financing charges) of capital
improvements made to the Project which may be required by any government
authority or which will improve the operating efficiency of the Project
(provided, however, that the amount of such amortization for improvements not
mandated by government authority shall not exceed in any year the amount of
costs reasonably determined by Landlord in its sole discretion to have been
saved by the expenditure either through the reduction or minimization of
increases which would have otherwise occurred).

          (e) Real Property Taxes including all taxes, assessments (general and
special) and other impositions or charges which may be taxed, charged, levied,
assessed or imposed upon all or any portion of or in relation to the Project or
any portion thereof, any leasehold estate in the Premises or measured by Rent
from the Premises, including any increase caused by the transfer, sale or
encumbrance of the Project or any portion thereof.  "Real Property Taxes" shall
also include any form of assessment, levy, penalty, charge or tax (other than
estate, inheritance, net income, or franchise taxes) imposed by any authority
having a direct or indirect power to tax or charge, including, without
limitation, any city, county, state federal or any improvement or other
district, whether such tax is (l) determined by the value of the

                                                                       PAGE 6
<PAGE>
 
Project or the Rent or other sums payable under this Lease; (2) upon or with
respect to any legal or equitable interest of Landlord in the Project or any
part thereof; (3) upon this transaction or any document to which Tenant is a
party creating a transfer in any interest in the Project, (4) in lieu of or as a
direct substitute in whole or in part of or in addition to any real property
taxes on the Project, (5) based on any parking spaces or parking facilities
provided in the Project, or (6) in consideration for services, such as police
protection, fire protection, street, sidewalk and roadway maintenance, refuse
removal or other services that may be provided by any governmental or quasi-
governmental agency from time to time which were formerly provided without
charge or with less charge to property owners or occupants.

          (f) Landlord agrees that Expenses as defined in Section 4(c) shall not
include leasing commissions; payments of principal and interest on any
mortgages, deeds of trust or other encumbrances upon the Project; depreciation
of the capital cost of capital improvements except as provided at 4(c)(1)(d);
Landlord's executive salaries, management fees in excess of market rates; costs
resulting from defective design or construction of the Project; costs incurred
in connection with entering into new leases; or costs of disputes under existing
leases.  In no event shall Expenses include any charge for which Landlord
receives reimbursement from insurance or from another Tenant, nor shall any item
of Expense be counted more than once, nor shall Landlord collect more than one
hundred percent (100%) of Expenses.

            2)  ANNUAL ESTIMATE OF EXPENSES, TENANT'S SHARE

     At the commencement of each calendar year, beginning with calendar year
1999, Landlord shall estimate Tenant's share of Expenses for the remainder of
the calendar year, and at the commencement of each calendar year thereafter,
Landlord shall estimate Tenant's Share of Expenses for the coming year by
multiplying the estimated annual Project Expenses by Tenant's Share and
subtracting the Annual Expense Base.

            3)  MONTHLY PAYMENT OF EXPENSES

     Tenant shall pay to Landlord, monthly in advance, as Additional Rent, one-
twelfth (1/12) of the Annual Estimate of Tenant's Share of Expenses beginning on
January 1, 1999.  As soon as practical following each calendar year, Landlord
shall prepare an accounting of actual Expenses incurred during the prior
calendar year and such accounting shall reflect Tenant's Share of Expenses.  If
the Additional Rent paid by Tenant under this Section 4.c.3 during the preceding
calendar year was less than the actual amount of Tenant's Share of Expenses,
Landlord shall so notify Tenant and Tenant shall pay such amount to Landlord
within 30 days of receipt of such notice. 

                                                                       PAGE 7
<PAGE>
 
Such amount shall be deemed to have accrued during the prior calendar year and
shall be due and payable from Tenant even though the term of this Lease has
expired or this Lease has been terminated prior to Tenant's receipt of this
notice. Tenant shall have thirty (30) days from receipt of such notice to
contest the amount due, failure to so notify Landlord shall represent final
determination of Tenant's Share of Expenses. If Tenant's payments were greater
than the actual amount, then such overpayment shall be credited by Landlord to
Tenant's Share of Expenses due under this Section 4.c.3, or if the Lease has
expired or been terminated, any overpayment net of other sums due from Tenant to
Landlord shall be refunded to Tenant by check.

            4)  RENT WITHOUT OFFSET AND LATE CHARGE

     As used herein, "Rent" shall mean all monetary sums due from Tenant to
Landlord.  All Base Monthly Rent shall be paid by Tenant to Landlord without
prior notice or demand in advance on the first day of every calendar month, at
the address shown in Section 1, or such other place as landlord may designate in
writing from time to time.  Whether or not so designated, all other sums due
from Tenant under this Lease shall constitute Additional Rent, payable without
prior notice or demand when specified in this Lease, but if not specified, then
within ten (10) days of demand.  All Rent shall be paid without any deduction or
offset whatsoever.  All Rent shall be paid in lawful currency of the United
States of America.  Proration of Rent due for any partial month shall be
calculated by dividing the number of days in the month for which Rent is due by
the actual number of days in that month and multiplying by the applicable
monthly rate.  Tenant acknowledges that late payment by Tenant to Landlord of
any Rent or other sums due under this Lease will cause Landlord to incur costs
not contemplated by this Lease, the exact amount of such cost being extremely
difficult and impracticable to ascertain.  Such costs include, without
limitation, processing and accounting charges and late charges that may be
imposed on Landlord by the terms of any encumbrance or note secured by the
Premises.  Therefore, if any Rent or other sum due from Tenant is not received
by the end of the 10th day after due (i.e. by the end of the 10th day of the
month for sums due on the first), Tenant shall pay to Landlord an additional sum
equal to 10% of such overdue payment.  Landlord and Tenant hereby agree that
such late charge represents a fair and reasonable estimate of the costs that
Landlord will incur by reason of any such late payment and that the late charge
is in addition to any and all remedies available to the Landlord and that the
assessment and/or collection of the late charge shall not be deemed a waiver of
any other default.  Additionally, all such delinquent Rent or other sums, plus
this late charge, shall bear interest at the rate of 12 percent per annum.  If
the interest rate specified in this Lease is higher than the rate permitted by
law, the interest rate is hereby decreased to the maximum legal interest rate
permitted by law.  Any payments of any kind returned for insufficient funds will
be subject to an

                                                                       PAGE 8
<PAGE>
 
additional handling charge of $25.00, and thereafter, Landlord may require
Tenant to pay all future payments of Rent or other sums due by money order or
cashier's check.

5.          PREPAID RENT

     Upon the execution of this Lease, Tenant shall, in addition to the payment
of the first month's Rent as set forth in Section 4.a, pay to Landlord the
prepaid Rent set forth in Section 1.k, and if Tenant is not in default of any
provisions of this Lease, such prepaid Rent shall be applied toward the Base
Monthly Rent for the months set forth in Section 1.k.  Landlord's obligations
with respect to the prepaid Rent are those of a debtor and not of a trustee, and
Landlord can commingle the prepaid Rent with Landlord's general funds.  Landlord
shall not be required to pay Tenant interest on the prepaid Rent.  Landlord
shall be entitled to immediately endorse and cash Tenant's prepaid Rent;
however, such endorsement and cashing shall not constitute Landlord's acceptance
of this Lease.  In the event Landlord does not accept this Lease, Landlord shall
return said prepaid Rent.

6.          DEPOSIT

     Upon execution of this Lease, Tenant shall deposit a security deposit and a
cleaning fee as set forth in Section 1.1 with Landlord.  If Tenant is in
default, Landlord, upon 5 days notice, can use the security deposit or any
portion of it to cure the default or to compensate Landlord for any damages
sustained by Landlord resulting from Tenant's default.  Upon demand, Tenant
shall immediately pay to Landlord a sum equal to the portion of the security
deposit expended or applied by Landlord to restore the security deposit to its
full amount.  In no event will Tenant have the right to apply any part of the
security deposit to any Rent or other sums due under this Lease.  If Tenant is
not in default at the expiration or termination of this Lease, Landlord shall
return the security deposit to Tenant, and retain the cleaning fee, which shall
equal 10% of first month's Base Monthly Rent or $125, whichever is greater.
Landlord's obligations with respect to the deposit are those of a debtor and not
of a trustee, and Landlord can commingle the security deposit with Landlord's
general funds.  Landlord shall not be required to pay Tenant interest on the
deposit.  Upon full execution of the lease, Landlord shall be entitled to
endorse and cash Tenant's prepaid deposit.  Each time the Base Monthly Rent is
increased, Tenant shall deposit additional funds with Landlord sum sufficient to
increase the security deposit to an amount which bears the same relationship to
the adjusted Base Monthly Rent as the initial security deposit bore to the
initial Base Monthly Rent.

7.          USE OF PREMISES AND PROJECT FACILITIES

     Tenant shall use the Premises solely for the purposes set forth in Section
1 and for no other purpose without obtaining the prior written consent of
Landlord. Tenant

acknowledges that neither Landlord nor any agent of Landlord has made any
representation or warranty with respect to the Premises or with respect to the
suitability of the Premises or the Project for the conduct of Tenant's business,
nor has Landlord agreed to undertake any modification, alteration or improvement
to the Premises or the Project, except as provided in writing in this Lease.
Tenant acknowledges that Landlord may from time to time, at its sole discretion,
make such modifications, alterations, deletions or improvements to the Project
as Landlord may deem necessary or desirable, without compensation or notice to
Tenant. Tenant shall promptly comply with all laws, ordinances, orders and
regulations affecting the Premises and the Project, including, without
limitation, any rules and regulations that may be attached to this Lease and to
any reasonable modifications to these rules and regulations as Landlord may
adopt from time to time. Tenant acknowledges that, except for Landlord's
obligations pursuant to Section 13, Tenant is solely responsible for ensuring
that the Premises comply with any and all governmental regulations applicable to
Tenant's conduct of business on the Premises, and that Tenant is solely
responsible for any alterations or improvements that may be required by such
regulations, now existing or hereafter adopted. Tenant shall not do or permit
anything to be done in or about the Premises or bring or keep anything in the
Premises that will in any way increase the premiums paid by Landlord on its
insurance related to the Project or which will in any way increase the premiums
for fire or casualty insurance carried by other tenants in the Project. Tenant
will not perform any act or carry on any practices that may injure the Premises
or the Project; that may be a nuisance or menace to other tenants in the
Project; or that shall in any way interfere with the quiet enjoyment of such
other tenants. Tenant shall not use the Premises for sleeping, washing clothes,
cooking or the preparation, manufacture or mixing of anything that might emit
any objectionable odor, noises, vibrations or lights onto such other tenants. If
sound insulation is required to muffle noise produced by Tenant on the Premises,
Tenant at its own cost shall provide all necessary insulation. Tenant shall not
do anything on the premises which will overload any existing parking or service
to the Premises. Pets and/or animals of any type shall not be kept on the
Premises.

     Landlord grants to Tenant and Tenant's customers, suppliers, employees and
invitees, a non-exclusive license to use the designated parking areas in the
Project for the use of motor vehicles during the term of this Lease.  Landlord
reserves the right at any time to grant similar non-exclusive use to other
tenants, to promulgate rules and regulations relating to the use of such parking
areas, including reasonable restrictions on parking by tenants and employees, to
designate specific spaces for the use of any tenant, to make changes in the
parking layout from time to time, and to establish reasonable time limits on
parking.  Overnight parking is prohibited and any vehicle violating this or any

lighting and low power usage (110 volt) for office machines and water for

     Landlord shall maintain, in good condition, the structural parts of the
Premises, which shall include only the foundations, bearing and exterior walls
(excluding glass), subflooring and roof (excluding skylights), the unexposed
electrical, plumbing and sewerage systems, including those portions of the
systems lying outside the Premises, gutters and downspouts on the Building and

the Premises to Landlord in the same condition as existed at the commencement of
the term, except for reasonable wear and tear or damage caused by fire or other
casualty for which Landlord has received all funds necessary for restoration of
the Premises from insurance proceeds.

14.       ALTERATIONS

     Upon completion of the initial Premises improvements, Tenant shall not make
any alterations to the Premises, or to the Project, including any changes to the
existing landscaping, without Landlord's prior written consent, which consent
(in the case of non-structural alterations) shall not be unreasonably withheld.
If Landlord gives its consent to such alterations, Landlord may post notices in
accordance with the laws of the state in which the premises are located.  Any
alterations made shall remain on and be surrendered with the Premises upon
expiration or termination of this Lease, except that Landlord may, within 30
days before or 30 days after expiration of the term, elect 

                                                                         PAGE 14
<PAGE>

Premises. If Landlord so elects, at its own cost Tenant shall restore the
Premises to the original condition, reasonable wear and tear excepted, before
the last day of the term or within 30 days after notice of its election is
given, whichever is later.

     Should Landlord consent in writing to Tenant's alteration of the Premises,
Tenant shall contract with a contractor approved by Landlord for the
construction of such alterations, shall secure all appropriate governmental
approvals and permits, and shall complete such alterations with due diligence in
compliance with plans and specifications approved by Landlord.  All such
construction shall be performed in a manner which will not interfere with the
quiet enjoyment of other tenants of the Project.  Tenant shall pay all costs for
such construction and shall keep the Premises and the Project free and clear of
all mechanics' liens which may result from construction by Tenant.

15.       RELEASE AND INDEMNITY

     A.   TENANT INDEMNITY

     Except as otherwise provided in this Section, Tenant shall indemnify,
defend (using legal counsel acceptable to Landlord) and save Landlord harmless
from all claims, suits, losses, damages, fines, penalties, liabilities and
expenses (including Landlord's personnel and overhead costs and attorneys fees
and other costs incurred in connection with claims, regardless of whether such
claims involve litigation) resulting from any actual or alleged injury
(including death) of any person or from any actual or alleged loss of or damage
to, any property arising out of or in connection with (i) Tenant's occupation,
use or improvement of the Premises, or that of its employees, agents or
contractors, (ii) Tenant's breach of its obligations hereunder, or (iii) any act
or omission of Tenant or any subtenant, licensee, assignee or concessionaire of
Tenant, or of any officer, agent, employee, guest or invitee of Tenant, or of
any such entity in or about the Premises.  Tenant agrees that the foregoing
indemnity specifically covers actions brought by its own employees.  This
indemnity with respect to acts or omissions during the term of this Lease shall
survive termination or expiration of this Lease.  The foregoing indemnity is
specifically and expressly intended to, constitute a waiver of Tenant's immunity
under Washington's Industrial Insurance Act, RCW Title 51, to the extent
necessary to provide Landlord with a full and complete indemnity from claims
made by Tenant and its employees, to the extent provided herein.  Tenant shall
promptly notify Landlord of casualties or accidents occurring in or about the
Premises.  LANDLORD AND TENANT ACKNOWLEDGE THAT THE INDEMNIFICATION PROVISIONS
OF SECTION 8.f. AND THIS SECTION 15 WERE SPECIFICALLY NEGOTIATED AND AGREED UPON
BY THEM.

                                                                         PAGE 15
<PAGE>
 
     B.   LANDLORD INDEMNITY

     Except as otherwise provided in this Section 15, Landlord shall indemnify,
defend (using legal counsel acceptable to Tenant) and save Tenant harmless from
all claims, suits, losses, fines, penalties, liabilities and expenses (including
Tenant's personnel and overhead costs and attorneys' fees and other costs
incurred in connection with claims, regardless of whether such claims involve
litigation) resulting from any actual or alleged injury (including death) of any
person or from any actual or alleged loss of or damage to, any property to the
extent caused by negligent acts of Landlord on the Common Areas.  Landlord
agrees that the foregoing indemnity specifically covers actions brought by its
own employees.  This indemnity with respect to actions or omissions during the
term of this Lease shall survive termination or expiration of this Lease.  The
foregoing indemnity is specifically and expressly intended to constitute a
waiver of Landlord's immunity under Washington's Industrial Insurance Act, RCW
Title 51, to the extent necessary to provide Tenant with a full and complete
indemnity from claims made by Landlord and its employees to the extent provided
herein.  LANDLORD AND TENANT ACKNOWLEDGE THAT THE INDEMNIFICATION PROVISIONS OF
SECTION 15 WERE SPECIFICALLY NEGOTIATED AND AGREED UPON BY THEM.

     C.   RELEASE

     Tenant hereby fully and completely waives and releases all claims against
Landlord for any losses or other damages sustained by Tenant or any person
claiming through Tenant resulting from any accident or occurrence in or upon the
Premises, including but not limited to: any defect in or failure of Project
equipment; any failure to make repairs; any defect, failure, surge in, or
interruption of Project facilities or services; any defect in or failure of
Common Areas; broken glass; water leakage; the collapse of any Building
component; or any act, omission or negligence of co-tenants, licensees or any
other persons or occupants of the Building, provided only that the release
contained in this Section 15.c shall not apply to claims for actual damage to
persons or property (excluding consequential damages such as lost profits)
resulting directly from Landlord's gross negligence or willful misconduct or
Landlord's breach of its express obligations under this Lease which Landlord has
not cured within a reasonable time after receipt of written notice of such
breach from Tenant.

     D.   LIMITATION ON INDEMNITY

     In compliance with RCW 4.24.115 as in effect on the date of this Lease, all
provisions of this Lease pursuant to which Landlord or Tenant (the "Indemnitor")
agrees to indemnify the other (the "Indemnitee") against liability for damages
arising out of bodily injury to Persons or damage to property relative to the
construction, 

                                                                         PAGE 16
<PAGE>
 
alteration, repair, addition to, subtraction from, improvement to, or
maintenance of, any building, road, or other structure, project, development, or
improvement attached to real estate, including the Premises, (i) shall not apply
to damages caused by or resulting from the sole negligence of the Indemnitee,
its agents or employees, and (ii) to the extent caused by or resulting from the
concurrent negligence of (a) the Indemnitee or the Indemnitee's agents or
employees, and (b) the Indemnitor or the Indemnitor's agents or employees, shall
apply only to the extent of the Indemnitor's negligence; PROVIDED, HOWEVER, the
limitations on indemnity set forth in this Section shall automatically and
without further act by either Landlord or Tenant be deemed amended so as to
remove any of the restrictions contained in this Section no longer required by
then applicable law.

     E.   DEFINITIONS

     As used in any Section establishing indemnity or release of Landlord,
"Landlord" shall include Landlord, its partners, officers, agents, employees and
contractors, and "Tenant" shall include Tenant and any person or entity claiming
through Tenant.

16.       INSURANCE

     Tenant, at its cost, shall maintain public liability and property damage
insurance and products liability insurance with a single combined liability
limit of $1,000,000, insuring against all liability of Tenant and its
representatives, employees, invitees, and agents arising out of or in connection
with Tenant's use or occupancy of the Premises.  Public liability insurance,
products liability insurance and property damage insurance shall insure
performance by Tenant of the indemnity provisions of Section 15.  Landlord shall
be named as additional insured and the policy shall contain cross-liability
endorsements.  On all its personal property, at its cost, Tenant shall maintain
a policy of standard fire and extended coverage insurance with vandalism and
malicious mischief endorsements and "all risk" coverage on all Tenant's
improvements and alterations, including without limitation, all items of Tenant
responsibility described in Section 13 in or about the Premises, to the extent
of at least 90% of their full replacement value.  The proceeds from any such
policy shall be used by Tenant for the replacement of personal property and the
restoration of Tenant's improvements or alterations.  All insurance required to
be provided by Tenant under this Lease shall release Landlord from any claims
for damage to business or to any person or the Premises and the Project, and to
Tenant's fixtures, personal property, improvements and alterations in or on the
Premises or the Project, caused by or resulting from risks insured against under
any insurance policy carried by Tenant in force at the time of such damage.  In
addition, Tenant hereby independently releases Landlord from any and all claims
for damage to business or to 

                                                                         PAGE 17
<PAGE>
 
any person or the Premises and the Project, and to Tenant's fixtures, personal
property, improvements and alterations in or on the Premises or the Project,
caused by or resulting from risks that would have been insured against under any
insurance policy required by this Lease to be carried by Tenant, even if Tenant
failed to so carry the required insurance. All insurance required to be provided
by Tenant under this Lease: (a) shall be issued by Insurance companies
authorized to do business in the state in which the premises are located with a
financial rating of at least an A+XII status as rated in the most recent edition
of Best's Insurance Reports; (b) shall be issued as a primary policy; and (c)
shall contain an endorsement requiring at least 30 days prior written notice of
cancellation to Landlord and Landlord's lender, before cancellation or change in
coverage, scope or amount of any policy. Tenant shall deliver a certificate or
copy of such policy together with evidence of payment of all current premiums to
Landlord within 30 days of execution of this Lease. If Tenant fails at any time
to maintain the insurance required by this Lease, and fails to cure such default
within five (5) business days of written notice from Landlord then, in addition
to all other remedies available under this Lease and applicable law, Landlord
may purchase such insurance on Tenant's behalf and the cost of such insurance
shall be Additional Rent due within ten (10) days of written invoice from
Landlord to Tenant.

17.       DESTRUCTION

     If during the term, the Premises or Project are more than 10% destroyed
from any cause, or rendered inaccessible or unusable from any cause, Landlord
may, in its sole discretion, terminate this Lease by delivery of notice to
Tenant within 30 days of such event without compensation to Tenant.  If in
Landlord's estimation, the Premises cannot be restored within 90 days following
such destruction, the Landlord shall notify Tenant and Tenant may terminate this
Lease by delivery of notice to Landlord within 30 days of receipt of Landlord's
notice.  If neither Landlord nor Tenant terminates this Lease as provided above,
then Landlord shall commence to restore the Premises in compliance with then
existing laws and shall complete such restoration with due diligence.  In such
event, this Lease shall remain in full force and effect, but there shall be an
abatement of Base Monthly Rent and Tenant's Share of Expenses between the date
of destruction and the date of completion of restoration, based on the extent to
which destruction interferes with Tenant's use of the Premises.

18.       CONDEMNATION

     A.   TAKING

     If all of the Premises are taken by Eminent Domain, this Lease shall
terminate as of the date Tenant is required to vacate the Premises and all Base
and Additional 

                                                                         PAGE 18
<PAGE>
 
Rent shall be paid to that date. The term "Eminent Domain" shall include the
taking or damaging of property by, through or under any governmental or
statutory authority, and any purchase or acquisition in lieu thereof, whether
the damaging or taking is by government or any other person. If, in the
reasonable judgment of Landlord, a taking of any part of the Premises by Eminent
Domain renders the remainder thereof unusable for the business of Tenant (or the
cost of restoration of the Premises is not commercially reasonable), the Lease
may, at the option of either party, be terminated by written notice given to the
other party not more than thirty (30) days after Landlord gives Tenant written
notice of the taking, and such termination shall be effective as of the date
when Tenant is required to vacate the portion of the Premises so taken. If this
Lease is so terminated, all Base and Additional Rent shall be paid to the date
of termination. Whenever any portion of the Premises is taken by Eminent Domain
and this Lease is not terminated, Landlord shall at its expense proceed with all
reasonable dispatch to restore, to the extent of available proceeds and to the
extent it is reasonably prudent to do so, the remainder of the Premises to the
condition they were in immediately prior to such taking, and Tenant shall at its
expense proceed with all reasonable dispatch to restore its personal property
and all improvements made by it to the Premises to the same condition they were
in immediately prior to such taking. The Base and Additional Rent payable
hereunder shall be reduced from the date Tenant is required to partially vacate
the Premises in the same proportion that the Rentable Area taken bears to the
total Rentable Area of the Premises prior to taking.

     B.   AWARD

     Landlord reserves all right to the entire damage award or payment for any
taking by Eminent Domain, and Tenant waives all claim whatsoever against
Landlord for damages for termination of its leasehold interest in the Premises
or for interference with its business.  Tenant hereby grants and assigns to
Landlord any right Tenant may now have or hereafter acquire to such damages and
agrees to execute and deliver such further instruments of assignment as Landlord
may from time to time request.  Tenant shall, however, have the right to claim
from the condemning authority all compensation that may be recoverable by Tenant
on account of any loss incurred by Tenant in moving Tenant's merchandise,
furniture, trade fixtures and equipment, provided, however, that Tenant may
claim such damages only if they are awarded separately in the eminent domain
proceeding and not out of or as part of Landlord's damages.

19.       ASSIGNMENT OR SUBLEASE

     Tenant shall not assign or encumber its interest in this Lease or the
Premises or sublease all or any part of the Premises or allow any other person
or entity (except Tenant's authorized representatives, employees, invitees, or
guests) to occupy or use 

                                                                         PAGE 19
<PAGE>
 
all or any part of the Premises without first obtaining Landlord's consent which
Landlord may withhold or condition in its sole discretion, provided only that
(a) Landlord shall consent to a merger or combination and associated assignment
or sublease for the same use where (i) the succeeding entity has a net worth
equal to or greater than that of Tenant immediately prior to the assignment or
sublease and (ii) Tenant's management team is a substantial part of the
management team of the successor entity and (b) Landlord shall consent to a
sublease for the same use to a subtenant of equal or greater financial strength
from Tenant. No assignment or sublease shall release Tenant from the obligation
to perform all obligations under this Lease. Any assignment, encumbrance or
sublease without Landlord's written consent shall be voidable and at Landlord's
election, shall constitute a default. If Tenant is a partnership, a withdrawal
or change, voluntary, involuntary or by operation of law of any partner, or the
dissolution of the partnership, shall be deemed a voluntary assignment. If
Tenant consists of more than one person, a purported assignment, voluntary or
involuntary or by operation of law from one person to the other shall be deemed
a voluntary assignment. If Tenant is a corporation, any dissolution, merger,
consolidation or other reorganization of Tenant, or sale or other transfer of a
controlling percentage of the capital stock of Tenant, or the sale of at least
25% of the value of the assets of Tenant shall be deemed a voluntary assignment.
The phrase "controlling percentage" means ownership of and right to vote stock
possessing at least 25% of the total combined voting power of all classes of
Tenant's capital stock issued, outstanding and entitled to vote for election of
directors. This Section 19 shall not apply to corporations the stock of which is
traded through an exchange or over the counter. All rent received by Tenant from
its subtenants in excess of the Rent payable by Tenant to Landlord under this
Lease shall be paid to Landlord, or any sums to be paid by an assignee to Tenant
in consideration of the assignment of this Lease shall be paid to Landlord. If
Tenant requests Landlord to consent to a proposed assignment or subletting,
Tenant shall pay to Landlord, whether or not consent is ultimately given, $100
or Landlord's reasonable attorney's fees incurred in connection with such
request, whichever is greater, not to exceed $250 per transaction.

     No interest of Tenant in this Lease shall be assignable by involuntary
assignment through operation of law (including without limitation the transfer
of this Lease by testacy or intestacy).  Each of the following acts shall be
considered an involuntary assignment:  (a) if Tenant is or becomes bankrupt or
insolvent, makes an assignment for the benefit of creditors, or institutes
proceedings under the Bankruptcy Act in which Tenant is the bankrupt; or if
Tenant is a partnership or consists of more than one person or entity, if any
partner of the partnership or other person or entity is or becomes bankrupt or
insolvent, or makes an assignment for the benefit of creditors; or (b) if a writ
of attachment or execution is levied on this Lease; or (c) if in any proceeding
or action to which Tenant is a party, a receiver is appointed with authority to
take possession of the Premises.  An involuntary assignment shall constitute a

                                                                         PAGE 20
<PAGE>
 
default by Tenant and Landlord shall have the right to elect to terminate this
Lease, in which case this Lease shall not be treated as an asset of Tenant.

20.       DEFAULT

     The occurrence of any of the following shall constitute a default by
Tenant:  (a) a failure to pay Rent or other charge when due provided that
Landlord shall not exercise any of its rights under this Section 20 until
Landlord has given Tenant notice of such default and Tenant has failed to pay
such rent or other charge within three (3) days of the effective date of such
notice; (b) abandonment and vacation of the Premises (failure to occupy and
operate the Premises for ten consecutive days shall be conclusively deemed an
abandonment and vacation); or (c) failure to perform any other provision of this
Lease, provided that Landlord shall not exercise any of its rights under this
Section 20(c) until Landlord has given Tenant notice of such default and Tenant
has failed to cure such default and provided further that if more than thirty
(30) days are required to complete such performance, Landlord shall not exercise
any of its rights if Tenant commences to cure such default within the thirty
(30) day period and thereafter diligently pursues such cure completion.  The
notice required by this Section is intended to satisfy any and all notice
requirements imposed by law on Landlord and is not in addition to any such
requirement.

21.       LANDLORD'S REMEDIES

     Landlord shall have the following remedies if Tenant is in default and has
failed to cure such default within any applicable cure period.  (These remedies
are not exclusive; they are cumulative and in addition to any remedies now or
later allowed by law):  Landlord may terminate Tenant's right to possession of
the Premises at any time.  No act by Landlord other than giving notice to Tenant
shall terminate this Lease.  Acts of maintenance, efforts to relet the Premises,
or the appointment of a receiver on Landlord's initiative to protect Landlord's
interest under this Lease shall not constitute a termination of Tenant's right
to possession.  Upon termination of Tenant's right to possession, Landlord has
the right to  recover from Tenant:  (1) the worth of the unpaid Rent that had
been earned at the time of termination of  Tenant's right to possession; (2) the
worth of the amount of the unpaid Rent that would have been earned after the
date of termination of Tenant's right to possession; (3) any other amount,
including but not limited  to, expenses incurred to relet the Premises, court,
attorney and collection costs, necessary to compensate Landlord for all
detriment caused by Tenant's default.  "The Worth," as used for Item (1) in this
Paragraph 21 is to be computed by allowing interest at the rate of 12 percent
per annum.  If the interest rate specified in this Lease is higher than the rate
permitted by law, the interest rate is hereby decreased to the maximum legal
interest rate permitted by law.  "The Worth" as used for Item (2) in this
Paragraph 21 is to be computed by 

                                                                         PAGE 21
<PAGE>
 
discounting the amount at the discount rate of the Federal Reserve Bank of San
Francisco at the time of termination of Tenant's right of possession.

22.       ENTRY ON PREMISES

     Landlord and its authorized representatives shall have the right to enter
the Premises at all reasonable times and upon reasonable notice except in an
emergency, when no notice shall be required, for any of the following purposes:
(a) to determine whether the Premises are in good condition and whether Tenant
is complying with its obligations under this Lease; (b) to do any necessary
maintenance and to make any restoration to the Premises or the Project that
Landlord has the right or obligation to perform; (c) to post "for sale" signs at
any time during the term, to post "for rent" or "for lease" signs during the
last 90 days of the term, or during any period while Tenant is in default; (d)
to show the Premises to prospective brokers, agents, buyers, tenants or persons
interested in leasing or purchasing the Premises, at any time during the term;
or (e) to repair, maintain or improve the Project and to erect scaffolding and
protective barricades around and about the Premises but not so as to prevent
entry to the Premises and to do any other act or thing necessary for the safety
or preservation of the Premises or the Project.  Landlord shall not be liable in
any manner for any inconvenience, disturbance, loss of business, nuisance or
other damage arising out of Landlord's entry onto the Premises as provided in
this Section 22.  Tenant shall not be entitled to an abatement or reduction of
Rent if Landlord exercises any rights reserved in this Section 22.  Landlord
shall conduct his activities on the Premises as provided herein in a
commercially reasonable manner so as to limit inconvenience, annoyance or
disturbance to Tenant to the maximum extent practicable.  For each of these
purposes, Landlord shall at all times have and retain a key with which to unlock
all the doors in, upon and about the Premises, excluding Tenant's vaults and
safes.  Tenant shall not alter any lock or install a new or additional lock or
bolt on any door of the Premises without prior written consent of Landlord.  If
Landlord gives its consent, Tenant shall furnish Landlord with a key for any
such lock.

23.       SUBORDINATION

     Without the necessity of any additional document being executed by Tenant
for the purpose of effecting a subordination, and at the election of Landlord or
any mortgagee or any beneficiary of a Deed of Trust with a lien on the Project
or any ground lessor with respect to the Project, this Lease shall be subject
and subordinate at all times to (a) all ground leases or underlying leases which
may now exist or hereafter be executed affecting the Project, and (b) the lien
of any mortgage or deed of trust which may now exist or hereafter be executed in
any amount for which the Project, ground leases or underlying leases, or
Landlord's interest or estate in any of said items is specified as security.  In
the event that any ground lease or underlying 

                                                                         PAGE 22
<PAGE>
 
lease terminates for any reason or any mortgage or Deed of Trust is foreclosed
or a conveyance in lieu of foreclosure is made for any reason, Tenant shall,
notwithstanding any subordination, attorn to and become the Tenant of the
successor in interest to Landlord, at the option of such successor in interest.
Tenant covenants and agrees to execute and deliver, upon demand by Landlord and
in the form requested by Landlord any additional documents evidencing the
priority or subordination of this Lease with respect to any such ground lease or
underlying leases or the lien of any such mortgage or Deed of Trust. Tenant
hereby irrevocably appoints Landlord as attorney-in-fact of Tenant to execute,
deliver and record any such document in the name and on behalf of Tenant.

     Tenant, within ten days from notice from Landlord, shall execute and
deliver to Landlord, in recordable form, certificates stating that this Lease is
not in default, is unmodified and in full force and effect, or in full force and
effect as modified, and stating the modifications.  This certificate should also
state the amount of current monthly Rent, the dates to which Rent has been paid
in advance, and the amount of any security deposit and prepaid Rent.  Failure to
deliver this certificate to Landlord within ten days shall be conclusive upon
Tenant that this Lease is in full force and effect and has not been modified
except as may be represented by Landlord.

24.       NOTICE

     Any notice, demand or request required hereunder shall be given in writing
to the party's facsimile number or address set forth in Section I hereof by any
of the following means:  (a) personal service; (b) electronic communication,
whether by telex, telegram or facsimile; (c) overnight courier; or (d)
registered or certified, first class mail, return receipt requested.  Such
addresses may be changed by notice to the other parties given in the same manner
as above provided.  Any notice, demand or request sent pursuant to either
subsection (a) or (b) hereof shall be deemed received upon such personal service
or upon dispatch by electronic means with electronic confirmation of receipt.
Any notice, demand or request sent pursuant to subsection (c) hereof shall be
deemed received on the business day immediately following deposit with the
overnight courier and, if sent pursuant to subsection (d), shall be deemed
received forty-eight (48) hours following deposit in the U.S. mail.

25.       WAIVER

     No delay or omission in the exercise of any right or remedy by Landlord
shall impair such right or remedy or be construed as a waiver.  No act or
conduct of Landlord, including without limitation, acceptance of the keys to the
Premises, shall constitute an acceptance of the surrender of the Premises by
Tenant before the expiration of the term.  Only written notice from Landlord to
Tenant shall constitute 

                                                                         PAGE 23
<PAGE>
 
acceptance of the surrender of the Premises and accomplish termination of the
Lease. Landlord's consent to or approval of any act by Tenant requiring
Landlord's consent or approval shall not be deemed to waive or render
unnecessary Landlord's consent to or approval of any subsequent act by Tenant.
Any waiver by Landlord of any default must be in writing and shall not be a
waiver of any other default concerning the same or any other provision of the
Lease. TENANT SPECIFICALLY ACKNOWLEDGES AND AGREES THAT, WHERE TENANT HAS
RECEIVED A NOTICE TO CURE DEFAULT (WHETHER RENT OR NON-RENT), NO ACCEPTANCE BY
LANDLORD OF RENT SHALL BE DEEMED A WAIVER OF SUCH NOTICE, AND, INCLUDING BUT
WITHOUT LIMITATION, NO ACCEPTANCE BY LANDLORD OF PARTIAL RENT SHALL BE DEEMED TO
WAIVE OR CURE ANY RENT DEFAULT. LANDLORD MAY, IN ITS DISCRETION, AFTER RECEIPT
OF PARTIAL PAYMENT OF RENT, REFUND SAME AND CONTINUE ANY PENDING ACTION TO
COLLECT THE FULL AMOUNT DUE, OR MAY MODIFY ITS DEMAND TO THE UNPAID PORTION. IN
EITHER EVENT THE DEFAULT SHALL BE DEEMED UNCURED UNTIL THE FULL AMOUNT IS PAID
IN GOOD FUNDS.

26.       SURRENDER OF PREMISES; HOLDING OVER

     Upon expiration of the term, Tenant shall surrender to Landlord the
Premises and all Tenant improvements and alterations in good condition, except
for ordinary wear and tear and alterations Tenant has the right or is obligated
to remove under the provisions of Section 14 herein.  Tenant shall remove all
personal property including, without limitation, all wallpaper, paneling and
other decorative improvements or fixtures and shall perform all restoration made
necessary by the removal of any alterations or Tenant's personal property before
the expiration of the term, including for example, restoring all wall surfaces
to their condition prior to the commencement of this Lease.  Landlord can elect
to retain or dispose of in any manner Tenant's personal property not removed
from the Premises by Tenant prior to the expiration of the term.  Tenant waives
all claims against Landlord for any damage to Tenant resulting from Landlord's
retention or disposition of Tenant's personal property.  Tenant shall be liable
to Landlord for Landlord's cost for storage, removal or disposal of Tenant's
personal property.

     If Tenant, with Landlord's consent, remains in possession of the Premises
after expiration or termination of the term, or after the date in any notice
given by Landlord to Tenant terminating this Lease, such possession by Tenant
shall be deemed to be a month-to-month tenancy terminable as provided under
Washington law, by either party.  All provisions of this Lease, except those
pertaining to term and Rent, shall apply to the month-to-month tenancy.  During
any holdover term, Tenant shall pay Base Monthly Rent in an amount equal to 125%
of Base Monthly Rent for the last full 

                                                                         PAGE 24
<PAGE>
 
calendar month during the regular term plus 100% of Tenant's share of Expenses
pursuant to Section 4.c.3.

27.       BUILDING PLANNING

     If Landlord requires the Premises for use in conjunction with another suite
or for other reasons connected with the Project planning program, upon notifying
Tenant in writing, Landlord shall have the right to move Tenant to other space
in the Project that is substantially the same in size, configuration and tenant
improvements, such move (including out-of-pocket ancillary costs such as
reprinting of stationary) to be at Landlord's sole cost and expense.  Upon such
move, the terms and conditions of the original Lease shall remain in full force
and effect, save and excepting that a revised Exhibit "A" shall become part of
this Lease and shall reflect the location of the new space and Section 1 of this
Lease shall be amended to include and state all correct data as to the new
space.  Notwithstanding the above, if Landlord notifies Tenant of Landlord's
intention to exercise the relocation rights provided in this Section 27, Tenant
may, within 30 days of receipt of such notice, notify Landlord of Tenant's
intention to terminate this Lease.  If Tenant so notifies Landlord, then either
(i) Landlord shall, within 30 days of receipt of Tenant's notice, rescind the
relocation notice and this Lease shall continue unaltered, or (ii) this Lease
shall terminate 90 days following Landlord's receipt of Tenant's notice without
any liability to Landlord or Tenant for such early termination.

                                                                         PAGE 25
<PAGE>
 
identified in Section 1, who shall be compensated by Landlord. Landlord and
Tenant recognize that it is possible that they may hereafter make additional
agreements regarding further extension or renewal of this Lease or a new lease
or leases for all or one or more parts of the Premises or other space in the
Project for a term or terms commencing after the Commencement Date of this
Lease. Landlord and Tenant recognize that it is also possible that they may
hereafter modify this Lease to add additional space or to substitute space as
part of the Premises. If any such additional agreements, new leases or
modifications to this Lease are made, Landlord shall not have any obligation to
pay any compensation to any real estate broker or to any other third person
engaged by Tenant to render services to Tenant in connection with negotiating
such matters, regardless of whether under the circumstances such person is or is
not regarded by the law as an agent of Landlord.

     E.   OTHER CHARGES

     If either party commences any litigation against the other party or files
an appeal of a decision arising out of or in connection with the Lease, the
prevailing party shall be entitled to recover from the other party reasonable
attorney's fees and costs of suit.  If Landlord employs a collection agency to
recover delinquent charges, Tenant agrees to pay all collection agency and
attorneys' fees charged to Landlord in addition to Rent, late charges, interest
and other sums payable under this Lease.  Tenant shall pay a charge of $75 to
Landlord for preparation of a demand for delinquent Rent.

     F.   FORCE MAJEURE

     Landlord shall not be deemed in default hereof nor liable for damages
arising  from its failure to perform its duties or obligations hereunder if such
is due to causes beyond its reasonable control, including, but not limited to,
acts of God, acts of civil or military authorities, fires, floods, windstorms,
earthquakes, strikes or labor disturbances, civil commotion, delays in
transportation, governmental delays or war.

     G.   RULES AND REGULATIONS

     Tenant shall faithfully observe and comply with the "Rules and
Regulations", a copy of which is attached hereto, and all reasonable and
nondiscriminatory modifications thereof and additions thereto from time to time
put into effect by Landlord.  Landlord shall not be responsible to Tenant for
the violation or non-performance by any other tenant or occupant of the building
or Project of said tenant or occupant's lease or of any of said Rules and
Regulations.

                                                                         PAGE 26
<PAGE>
 
     H.   LANDLORD'S SUCCESSORS

     In the event of a sale or conveyance by Landlord of the Project, the same
shall operate to release Landlord from any liability under this Lease, and in
such event Landlord's successor in interest shall be solely responsible for all
obligations of Landlord under this Lease.

     I.   INTERPRETATION

     This Lease shall be construed and interpreted in accordance with the laws
of the state in which the premises are located.  This Lease constitutes the
entire agreement between the parties with respect to the Premises and the
Project, except for such guarantees or modifications as may be executed in
writing by the parties from time to time.  When required by the context of this
Lease, the singular shall include the plural, and the masculine shall include
the feminine and/or neuter.  "Party" shall mean Landlord or Tenant.  If more
than one person or entity constitutes Landlord or Tenant, the obligations
imposed upon that party shall be joint and several.  The enforceability,
invalidity or illegality of any provision shall not render the other provisions
unenforceable, invalid or illegal.

     J.   CLEAN AIR ACT

     Tenant acknowledges that Landlord has not made any portion of the Premises
or the Building accessible for smoking in compliance with WAC 296-62-12000.  If
Tenant wishes to make any portion of the Premises accessible for smoking, Tenant
shall make all improvements necessary to comply with all applicable governmental
rules and regulations.  Tenant acknowledges that the indemnity contained in
Section 15 of the Lease includes, but is not limited to claims based on the
presence of tobacco smoke as a result of the activities of Tenant, its
employees, agents, or guests.

29.       CARDKEY SYSTEM

     Tenant shall be allowed to install a card access entry pad on the exterior
of the main entrance to the Premises, so as to work in conjunction with its
existing card key system in the Project.  At the expiration of the Lease, Tenant
at its own cost shall remove such card access entry pad and repair any damage
resulting therefrom.

     This LOAN AND SECURITY AGREEMENT dated _____________, between SILICON
VALLEY BANK ("Bank"), whose address is 3003 Tasman Drive, Santa Clara,
California 95054 with a loan production office located 915 - 118th Avenue S.E.,
Suite 250, Bellevue, WA 98005 and ONYX SOFTWARE CORPORATION ("Borrower"), whose
address is 330 120th Avenue NE, Bellevue, Washington 98005, provides the terms
on which Bank will lend to Borrower and Borrower will repay Bank.  The parties
agree as follows:

1.   ACCOUNTING AND OTHER TERMS

     Accounting terms not defined in this Agreement will be construed following
GAAP Calculations and determinations must be made following GAAP.  The term
"financial statements" includes the notes and schedules.  The terms "including"
and includes" always mean "including (or includes) without limitation," in this
or any Loan Document.  This Agreement shall be construed to impart upon Bank a
duty to act reasonably at all times.

2.   LOAN AND TERMS OF PAYMENT

     2.1   CREDIT EXTENSIONS

     Borrower will pay Bank the unpaid principal amount of all Credit Extensions
and interest on the unpaid principal amount of the Credit Extensions.

          2.1.1    REVOLVING ADVANCES

          (a)      Bank will make Advances not exceeding (i) the lesser of (A)
the Committed Revolving Line or (B) the Borrowing Base, whichever is less, minus
(ii) the amount of all outstanding Letters of Credit (including drawn but
unreimbursed Letters of Credit). Advances of up to $1,000,000 outstanding in the
aggregate may be made without regard to any limitation under the Borrowing Base.
However, if Borrower requests Advances beyond $1,000,000 in the aggregate, total
Advances may not exceed 25% of eligible accounts receivable until the initial
accounts receivable audit has been performed. Once an accounts receivable audit
has been completed that is deemed satisfactory to the Bank, if the total
outstanding Advances exceed $1,000,000, the entire amount must comply with the
Borrowing Based limitation set forth above. Amounts borrowed under this Section
may be repaid and reborrowed during the term of this Agreement.

          (b)      To obtain an Advance, Borrower must notify Bank by facsimile
or telephone by 3:00 p.m. Pacific time on the Business Day the Advance is to be
made. Borrower must promptly confirm the notification by delivering to Bank the
Payment/Advance Form attached as Exhibit B. Bank will credit Advances to
<PAGE>
 
Borrower's deposit account. Bank may make Advances under this Agreement based on
instructions from a Responsible Officer or his or her designee or without
instructions if the Advances are necessary to meet Obligations which have become
due. Bank may rely on any telephone notice given by a person whom Bank believes
is a Responsible Officer or designee. Borrower will indemnify Bank for any loss
Bank suffers due to reliance.

          (c)     The Committed Revolving Line terminates on the Revolving
Maturity Date, when all Advances and other amounts due under this Agreement are
immediately payable.

          2.1.2   TERM LOAN ADVANCES

          (a)     Bank will make Term Loan Advances not exceeding the lesser of
(i) the Committed Term Loan, or (ii) the Term Loan Borrowing Base, whichever is
less. Amounts borrowed under this Section may not be repaid and reborrowed
during the term of this Agreement.

          (b)     To obtain a Term Loan Advance, Borrower must notify Bank by
facsimile or telephone by 3:00 p.m. Pacific time on the Business Day the Term
Loan Advance is to be made.  Borrower must promptly confirm the notification by
delivering to Bank the Payment/Advance Form attached as Exhibit B, along with
copies of appropriate equipment Invoices.  Bank will credit Term Loan Advances
to Borrower's deposit account.  Bank may make Term Loan Advances under this
Agreement based on Instructions from a Responsible Officer or his or her
designee or without instructions if the Term Loan Advances are necessary to meet
Obligations which have become due.  Bank may rely on any telephone notice given
by a person whom Bank believes is a Responsible Officer or designee.  Borrower
will indemnify Bank for any loss Bank suffers due to reliance.

          (c)     Bank shall make Term Loan Advances under the Committed Term
Loan, in accordance with the conditions described above, during the twelve month
period beginning with the date of this Agreement, and ending on that date which
is twelve months thereafter (the "Advance Period"). During the Advance Period,
interest shall be paid monthly, in arrears, on the first day of each month. At
the end of the Advance Period, the Committed Term Line shall convert to a fully
amortizing term loan, with thirty-six (36) equal monthly payments of principal,
plus interest. The first monthly payment of principal and interest shall be due
and payable on the first day of the first full month following the end of the
Advance Period. The final payment of all outstanding principal, plus any accrued
but unpaid interest, shall be due on the first day of that month which is
thirty-six (36) months from the end of the Advance Period (the "Term Loan
Maturity Date").

          2.1.3   LETTERS OF CREDIT

     Bank will issue or have issued Letters of Credit for Borrower's account not
exceeding (i) the lesser of the Committed Revolving Line or the Borrowing Base
minus (ii) the outstanding principal balance of the Advances; however, the face
amount of outstanding Letters of Credit (including drawn but unreimbursed
Letters of Credit and any Letter of Credit Reserve) may not exceed $8,000,000.
Each Letter of Credit will have an expiry date of no later than 180 days after
the Revolving Maturity Date, but Borrower's reimbursement obligation will be
secured by cash on terms acceptable to Bank at any time after the Revolving
Maturity Date if the term of this Agreement is not extended by Bank.

     2.2  OVERADVANCES

     If Borrower's Obligations under Section 2.1.1, and 2.1.3 exceed the lesser
of either (i) the Committed Revolving Line or (ii) the Borrowing Base, Borrower
must immediately pay Bank the excess.  In addition, if Borrower's Obligations
under Sections 2.1.1 and 2.1.3 exceed $1,000,000, and the Borrowing Base does
not support Advances in excess of $1,000,000, Borrower must immediately pay Bank
the excess.

interest period, plus 2.00% per annum, all as set forth in the LIBOR Supplement

above at its own discretion.  After an Event of Default, Obligations accrue

LIBOR Rate changes.  Interest is computed on a 360-day year for the actual
number of days elapsed.

on the outstanding principal balance at a per annum rate of 0.25% percentage
points above the Prime Rate.  After an Event of Default, Obligations accrue

notify Borrower when it debits Borrower's accounts.  These debits are not a set-
off. Payments received

8.   EVENTS OF DEFAULT

     Any one of the following is an Event of Default:

     8.1  PAYMENT DEFAULT

     If Borrower fails to pay any of the Obligations;

     8.2  COVENANT DEFAULT

     If Borrower does not perform any obligation in Section 6 or violates any
covenant in Section 7 or does not perform or observe any other material term,
condition or covenant in this Agreement, any Loan Documents, or in any agreement
between Borrower and Bank and as to any default under a term, condition or
covenant that can be cured, has not cured the default within 10 days after it
occurs, or if the default cannot be cured within 10 days or cannot be cured
after Borrower's attempts within 10 day period, and the default may be cured
within a reasonable time, then Borrower has an additional period (of not more
than 30 days) to attempt to cure the default.  During the additional time, the
failure to cure the default is not an Event of Default (but no Credit Extensions
will be made during the cure period);

                                     -11-
<PAGE>
 
     8.3  MATERIAL ADVERSE CHANGE

     (i)  If there occurs a material impairment in the perfection or priority of
Bank's security interest in the Collateral or in the value of such Collateral
which is not covered by adequate insurance or (ii) if Bank determines, based
upon information available to it and in its reasonable judgment, that there is a
reasonable likelihood that Borrower will fail to comply with one or more of the
financial covenants in Section 6 during the next succeeding financial reporting
period;

     8.4  ATTACHMENT

     If any material portion of Borrower's assets is attached, seized, levied
on, or comes into possession of a trustee or receiver and the attachment,
seizure or levy is not removed in 10 days, or if Borrower is enjoined,
restrained, or prevented by court order from conducting a material part of its
business or if a judgment or other claim becomes a Lien on a material portion of
Borrower's assets, or if a notice of lien, levy, or assessment is filed against
any of Borrower's assets by any government agency and not paid within 10 days
after Borrower receives notice.  These are not Events of Default if stayed or if
a bond is posted pending contest by Borrower (but no Credit Extensions will be
made during the cure period);

     8.5  INSOLVENCY

     If Borrower becomes insolvent or if Borrower begins an Insolvency
Proceeding or an Insolvency Proceeding is begun against Borrower and not
dismissed or stayed within 30 days (but no Credit Extensions will be made before
any Insolvency Proceeding is dismissed);

     8.6  OTHER AGREEMENTS

     If there is a default in any agreement between Borrower and a third party
that gives the third Party the right to accelerate any Indebtedness exceeding
$100,000 or that could cause a Material Adverse Change;

     8.7  JUDGMENTS

     If a money judgment(s) in the aggregate of at least $50,000 is rendered
against Borrower and is unsatisfied and unstayed for 10 days (but no Credit

     8.6  MISREPRESENTATIONS

     If Borrower or any Person acting for Borrower makes any material
misrepresentation or material misstatement now or later in any warranty or

<PAGE>
 
representation in this Agreement or in any writing delivered to Bank or to
induce Bank to enter this Agreement or any Loan Document.

9.   BANK'S RIGHTS AND REMEDIES

     9.1  RIGHTS AND REMEDIES

     When an Event of Default occurs and continues Bank may, without notice or
demand, do any or all of the following:

          (a)  Declare all Obligations immediately due and payable (but if an
Event of Default described in Section 8.5 occurs all Obligations are immediately
due and payable without any action by Bank);

          (b)  Stop advancing money or extending credit for Borrower's benefit
under this Agreement or under any other agreement between Borrower and Bank;

          (c)  Settle or adjust disputes and claims directly with account
debtors for amounts, on terms and in any order that Bank considers advisable;

          (d)  Make any payments and do any acts it considers necessary or
reasonable to protect its security interest in the Collateral.  Borrower will
assemble the Collateral if Bank requires and make it available as Bank
designates.  Bank may enter premises where the Collateral is located, take and
maintain possession of any part of the Collateral, and pay, purchase, contest or
compromise any Lien which appears to be prior or superior to its security
interest and pay all expenses incurred.  Borrower grants Bank a license to enter
and occupy any of its premises, without charge, to exercise any of Bank's rights
or remedies;

          (e)  Apply to the Obligations any (i) balances and deposits of
Borrower it holds, or (ii) any amount hold by Bank owing to or for the credit or
the account of Borrower;

          (f)  Ship, reclaim, recover, store, finish, maintain, repair, prepare
for sale, advertise for sale, and sell the Collateral; and

          (g)  Dispose of the Collateral according to the Code.

     9.2  POWER OF ATTORNEY

     Effective only when an Event of Default occurs and continues, Borrower
irrevocably appoints Bank as its lawful attorney to:  (i) endorse Borrower's
name on any checks or other forms of payment or security: (ii) sign Borrower's
name on any invoice or bill of lading for any Account or drafts against account
debtors, (iii) make, settle, and adjust all claims under Borrower's insurance
policies; (iv) settle and adjust 

                                     -13-
<PAGE>
 
disputes and claims about the Accounts directly with account debtors, for
amounts and on terms Bank determines reasonable; and (v) transfer the Collateral
into the name of Bank or a third party as the Code permits. Bank may exercise
the power of attorney to sign Borrower's name on any documents necessary to
perfect or continue the perfection of any security interest regardless of
whether an Event of Default has occurred. Bank's appointment as Borrower's
attorney in fact, and all of Bank's rights and powers, coupled with an interest,
are irrevocable until all Obligations have been fully repaid and performed and
Bank's obligation to provide Credit Extensions terminates.

     9.3  ACCOUNTS COLLECTION

     When an Event of Default occurs and continues, Bank may notify any Person
owing Borrower money of Bank's security interest in the funds and verify the
amount of the Account.  Borrower must collect all payments in trust for Bank
and, if requested by Bank, immediately deliver the payments to Bank in the form
received from the account debtor, with proper endorsements for deposit.

     9.4  BANK EXPENSES

     If Borrower fails to pay any amount or furnish any required proof of
payment to third persons Bank may make all or part of the payment or obtain
insurance policies required in Section 6.5, and take any action under the
policies Bank deems prudent.  Any amounts paid by Bank are Bank Expenses and
immediately due and payable, bearing interest at the then applicable rate and
secured by the Collateral.  No payments by Bank are deemed an agreement to make
similar payments in the future or Bank's waiver of any Event of Default.

     9.5  BANK'S LIABILITY FOR COLLATERAL

     If Bank complies with reasonable banking practices it is not liable for:
(a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral;
(c) any diminution in the value of the Collateral; or (d) any act or default of
any carrier, warehouseman, bailee, or other person.  Borrower bears all risk of
loss, damage or destruction of the Collateral.

     9.6  REMEDIES CUMULATIVE

     Bank's rights and remedies under this Agreement, the Loan Documents, and
all other agreements are cumulative.  Bank has all rights and remedies provided
under the Code, by law, or in equity.  Bank's exercise of one right or remedy is
not an election, and Bank's waiver of any Event of Default is not a continuing
waiver.  Bank's delay is not a waiver, election, or acquiescence.  No waiver is
effective unless signed by Bank and then is only effective for the specific
instance and purpose for which it was given.

                                     -14-

     9.7  DEMAND WAIVER

and nonpayment, notice of any default, nonpayment at maturity, release,
compromise, settlement, extension, or renewal of accounts, documents,
instruments, chattel paper, and guarantees held by Bank on which Borrower is
liable.

11.  CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER

     Washington law governs the Loan Documents without regard to principles of
conflicts of law.  Borrower and Bank each submit to the exclusive jurisdiction
of the State and Federal courts in King County, Washington.

BORROWER AND BANK EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE
OF ACTION ARISING OUT OF ANY OF THE LOAN DOCUMENTS OR ANY CONTEMPLATED
TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS.
EACH PARTY HAS REVIEWED THIS WAIVER WITH ITS COUNSEL.

assigns of each party.  Borrower may not assign this Agreement or any rights
under it without Bank's prior written consent which may be granted or withheld

part of, or any interest in, Bank's obligations, rights and benefits under this

     12.6  COUNTERPARTS

     This Agreement may be executed in any number of counterparts and by

     12.7  SURVIVAL

     All covenants, representations and warranties made in this Agreement
continue in full force while any Obligations remain outstanding.  The
obligations of Borrower in Section 12.2 to indemnify Bank will survive until all
statutes of limitations for actions that may be brought against Bank have run.

     12.8  CONFIDENTIALITY

     In handling any confidential information, Bank will exercise the same
degree of care that it exercises for its own proprietary information, but
disclosure of information may be made (i) to Bank's subsidiaries or affiliates
in connection with their business with Borrower, (ii) to prospective transferees
or purchasers of any interest in the Loans, (iii) as required by law,
regulation, subpoena, or other order, (iv) as required in connection with Bank's
examination or audit and (v) as Bank considers appropriate exercising remedies
under this Agreement.  Confidential information does not include information
that either:  (a) is in the public domain or in Bank's possession when disclosed
to Bank, or becomes part of the public domain after disclosure to Bank; or (b)
is disclosed to Bank by a third party, if Bank does not know that the third
party is prohibited from disclosing the information.

                         LIBOR SUPPLEMENT TO AGREEMENT

     This LIBOR Supplement to Agreement (the "Supplement") is a supplement to
the Loan and Security Agreement (the "Loan Agreement") between Silicon Valley
Bank ("Bank") and ONYX Software Corporation, a Washington corporation
("Borrower"), and forms a part of and is incorporated into the Loan Agreement.

     1.  Definitions.
         ----------- 

     "Business Day" means a day of the year (a) that is not a Saturday, Sunday
or other day on which banks in the State of California or the City of London are
authorized or required to close and (b) on which dealings are carried on in the
interbank market in which Bank customarily participates.

     "Interest Period" means for each LIBOR Rate Loan, a period of approximately
one, two or three months as the Borrower may elect, provided that the last day
                                                    --------                  
of an Interest Period for a LIBOR Rate Loan shall be determined in accordance
with the practices of the LIBOR interbank market as from time to time in effect,
provided, further, in all cases such period shall expire not later than the
- --------  -------                                                          
applicable Maturity Date.

     "Interest Rate" shall mean as to:  (a) Prime Rate Loans, a rate equal to
the Prime Rate; and (b) LIBOR Rate Loans, a rate of 2.00% per annum in excess of
the LIBOR Rate (based on the LIBOR Rate applicable for the Interest Period
selected by the Borrower).

     "LIBOR Base Rate" means, for any Interest Period for a LIBOR Rate Loan, the
rate of interest per annum determined by Bank to be the per annum rate of
interest as which deposits in United States Dollars are offered to Bank in the
London interbank market in which Bank customarily participates at 11:00 A.M.
(local time in such interbank market) TWO (2) BUSINESS DAYS before the first day
of such Interest Period for a period approximately equal to such Interest Period
and in an amount approximately equal to the amount of such Loan.

     "LIBOR Rate" shall mean, for any Interest Period for a LIBOR Rate Loan, a
rate per annum (rounded upwards, if necessary, to the nearest 1/16 of 1%) equal
to (i) the LIBOR Base Rate for such Interest Period divided by (ii) 1 minus the
Reserve Requirement for such Interest Period.

     "LIBOR Rate Loans" means any Loans made or a portion thereof on which
interest is payable based on the LIBOR Rate in accordance with the terms hereof.
<PAGE>
 
     "Prime Rate" means the variable rate of interest per annum, most recently
announced by Bank as its "prime rate," whether or not such announced rate is the
lowest rate available from Bank.  The interest rate applicable to the Prime Rate
Loans shall change on each date there is a change in the Prime Rate.

     "Prime Rate Loans" means any Loans made or a portion thereof on which
interest is payable based on the Prime Rate in accordance with the terms hereof.

     "Regulatory Change" means, with respect to Bank, any change on or after the
date of this Loan Agreement in United States federal, state or foreign laws or
regulations, including Regulation D, or the adoption or making on or after such
date of any interpretations, directives or requests applying to a class of
lenders including Bank of or under any United States federal or state, or any
foreign, laws or regulations (whether or not having the force of law) by any
court or governmental or monetary authority charged with the interpretation or
administration thereof.

     "Reserve Requirement" means, for any Interest Period, the average maximum
rate at which reserves (including any marginal, supplemental or emergency
reserves) are required to be maintained during such Interest Period under
Regulation D against "Eurocurrency liabilities" (as such term is used in
Regulation D) by member banks of the Federal Reserve System.  Without limiting
the effect of the foregoing, the Reserve Requirement shall reflect any other
reserves required to be maintained by Bank by reason of any Regulatory Change
against (i) any category of liabilities which includes deposits by reference to
which the LIBOR Rate is to be determined as provided in the definition of "LIBOR
Base Rate" or (ii) any category of extensions of credit or other assets which
include Loans.

     2.  Requests for Loans; Confirmation of Initial Loans.  Each LIBOR Rate
         -------------------------------------------------                  
Loan shall be made upon the irrevocable written request of Borrower RECEIVED BY
BANK NOT LATER THAN 11:00 A.M. (SANTA CLARA, CALIFORNIA TIME) ON THE BUSINESS
DAY THREE (3) BUSINESS DAYS PRIOR TO THE DATE SUCH LOAN IS TO BE MADE.  Each
such notice shall specify the date such Loan is to be made, which day shall be a
Business Day; the amount of such Loan, the Interest Period for such Loan, and
comply with such other requirements as Bank determines are reasonable or
desirable in connection therewith.

     Each written request for a LIBOR Rate Loan shall be in the form of a LIBOR
Rate Loan Borrowing Certificate as set forth on Exhibit A, which shall be duly
executed by the Borrower.

     EACH PRIME RATE LOAN SHALL BE MADE UPON THE IRREVOCABLE WRITTEN REQUEST OF
BORROWER RECEIVED BY BANK NOT LATER THEN 11:00 A.M. (SANTA CLARA, CALIFORNIA

                                      -2-
<PAGE>
 
TIME) ON THE BUSINESS DAY ONE (1) BUSINESS DAY PRIOR TO THE DATE SUCH LOAN IS TO
BE MADE.  Each such notice shall specify the date such Loan is to be made, which
day shall be a Business Day and the amount of such Loan, and comply with such
other requirements as Bank determines are reasonable or desirable in connection
therewith.

     3.  Conversion/Continuation of Loans.
         -------------------------------- 

         (a)  Borrower may from time to time submit in writing a request that
Prime Rate Loans be converted to LIBOR Rate Loans or that any existing LIBOR
Rate Loans continue for an additional Interest Period. Such request shall
specify the amount of the Prime Rate Loans which will constitute LIBOR Rate
Loans (subject to the limits set forth below) and the Interest Period to be
applicable to such LIBOR Rate Loans. Each written request for a conversion to a
LIBOR Rate Loan or a continuation of a LIBOR Rate Loan shall be substantially in
the form of a LIBOR Rate Conversion/Continuation Certificate as set forth on
Exhibit B, which shall be duly executed by the Borrower. Subject to the terms
and conditions contained herein THREE (3) BUSINESS DAYS AFTER BANK'S RECEIPT OF
SUCH A REQUEST FROM BORROWER, such Prime Rate Loans shall be converted to LIBOR
Rate Loans or such LIBOR Rate Loans shall continue, as the case may be provided
that:

              (i)    no Event of Default or event which with notice or passage
of time or both would constitute an Event of Default exists;

              (ii)   no party hereto shall have sent any notice of termination
of this Supplement or of the Loan Agreement.

              (iii)  Borrower shall have complied with such customary procedures
as Bank has established from time to time for Borrower's requests for LIBOR Rate
Loans;

              (iv)   the amount of a LIBOR Rate Loan shall be $500,000 or such
greater amount which is an integral multiple of $50,000; and

              (v)    Bank shall have determined that the Interest Period or
LIBOR Rate is available to Bank which can be readily determined as of the date
of the request for such LIBOR Rate Loan.

     Any request by Borrower to convert Prime Rate Loans to LIBOR Rate Loans or
continue any existing LIBOR Rate Loans shall be irrevocable.  Notwithstanding
anything to the contrary contained herein, Bank shall not be required to
purchase United States Dollar deposits in the London interbank market or other
applicable LIBOR Rate market to fund any LIBOR Rate Loans, but the provisions
hereof shall

                                      -3-
<PAGE>
 
be deemed to apply as if Bank had purchased such deposits to fund the LIBOR Rate
Loans.

          (b) Any LIBOR Rate Loans shall automatically convert to Prime Rate
Loans upon the last day of the applicable Interest Period, UNLESS BANK HAS
RECEIVED AND APPROVED A COMPLETE AND PROPER REQUEST TO CONTINUE SUCH LIBOR RATE
LOAN AT LEAST THREE (3) BUSINESS DAYS PRIOR TO SUCH LAST DAY in accordance with
the terms hereof. Any LIBOR Rate Loans shall, at Bank's option, convert to Prime
Rate Loans in the event that (i) an Event of Default, or event which with the
notice or passage of time or both would constitute an Event of Default, shall
exist, (ii) this Supplement or the Loan Agreement shall terminate, or (iii) the
aggregate principal amount of the Prime Rate Loans which have previously been
converted to LIBOR Rate Loans, or the aggregate principal amount of existing
LIBOR Rate Loans continued, as the case may be, at the beginning of an Interest
Period shall at any time during such Interest Period exceeds the Borrower's
availability under the Committed Revolving Line. Borrower agrees to pay to Bank,
upon demand by Bank (or Bank may, at its option, charge Borrower's loan account)
any amounts required to compensate Bank for any loss (including loss of
anticipated profits), cost or expense incurred by such person, as a result of
the conversion of LIBOR Rate Loans to Prime Rate Loans pursuant to any of the
foregoing.

          (c) On all Loans, Interest shall be payable by Borrower to Bank
monthly in arrears not later than the first (1st) day of each calendar month at
the applicable Interest Rate.

     4.   Additional Requirements/Provisions Regarding LIBOR Rate Loans; Etc.
          ------------------------------------------------------------------ 

          (a) IF FOR ANY REASON (INCLUDING VOLUNTARY OR MANDATORY PREPAYMENT OR
ACCELERATION), BANK RECEIVES ALL OR PART OF THE PRINCIPAL AMOUNT OF A LIBOR RATE
LOAN PRIOR TO THE LAST DAY OF THE INTEREST PERIOD FOR SUCH LOAN, BORROWER SHALL
IMMEDIATELY NOTIFY BORROWER'S ACCOUNT OFFICER AT BANK AND, ON DEMAND BY BANK,
PAY BANK THE AMOUNT (if any) by which (i) the additional interest which would
have been payable on the amount so received had it not been received until the
last day of such Interest Period exceeds (ii) the interest which would have been
recoverable by Bank by placing the amount so received on deposit in the
certificate of deposit markets or the offshore currency interbank markets or
United States Treasury investment products, as the case may be, for a period
starting on the date on which it was so received and ending on the last day of
such Interest Period at the interest rate determined by Bank in its reasonable
discretion.  Bank's determination as to such amount shall be conclusive absent
manifest error.

                                      -4-
<PAGE>
 
          (b) Borrower shall pay to Bank, upon demand by Bank, from time to time
such amounts as Bank may determine to be necessary to compensate it for any
costs incurred by Bank that Bank determines are attributable to its making or
maintaining of any amount receivable by Bank hereunder in respect of any Loans
relating thereto (such increases in costs and reductions in amounts receivable
being herein called "Additional Costs"), in each case resulting from any
Regulatory Change which:

              (i)    changes the basis of taxation of any amounts payable to
Bank under this Supplement in respect of any Loans (other than changes which
affect taxes measured by or imposed on the overall net income of Bank by the
jurisdiction in which such Bank has its principal office); or

              (ii)   imposes or modifies any reserve, special deposit or similar
requirements relating to any extensions of credit or other assets of, or any
deposits with or other liabilities of Bank (including any Loans or any deposits
referred to in the definition of "LIBOR Base Rate"); or

              (iii)  imposes any other condition affecting this Supplement (or
any of such extensions of credit or liabilities).

Bank will notify Borrower of any event occurring after the date of the Loan
Agreement which will entitle Bank to compensation pursuant to this section as
promptly as practicable after it obtains knowledge thereof and determines to
request such compensation.  Bank will furnish Borrower with a statement setting
forth the basis and amount of each request by Bank for compensation under this
Section 4.  Determinations and allocations by Bank for purposes of this Section
4 of the effect of any Regulatory Change on its costs of maintaining its
obligations to make Loans or of making or maintaining Loans or on amounts
receivable by it in respect of Loans, and of the additional amounts required to
compensate Bank in respect of any Additional Costs, shall be conclusive absent
manifest error.

          (c) Borrower shall pay to Bank, upon the request of Bank, such amount
or amounts as shall be sufficient (in the sole good faith opinion of such Bank)
to compensate it for any loss, costs or expense incurred by it as a result of
any failure by Borrower to borrow a Loan on the date for such borrowing
specified in the relevant notice of borrowing hereunder.

          (d) If Bank shall determine that the adoption or implementation of any
applicable law, rule, regulation or treaty regarding capital adequacy, or any
change therein, or any change in the interpretation or administration thereof by
any governmental authority, central bank or comparable agency charged with the

                                      -5-
<PAGE>
 
interpretation or administration thereof, or compliance by Bank (or its
applicable lending office) with any respect or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, central
bank or comparable agency, has or would have the effect of reducing the rate of
return on capital of Bank or any person or entity controlling Bank (a "Parent")
as a consequence of its obligations hereunder to a level below that which Bank
(or its Parent) could have achieved but for such adoption, change or compliance
(taking into consideration its policies with respect to capital adequacy) by an
amount deemed by Bank to be material, then from time to time, within 15 days
after demand by Bank, Borrower shall pay to Bank such additional amount or
amounts as will compensate Bank for such reduction.  A statement of Bank
claiming compensation under this Section and setting forth the additional amount
or amounts to be paid to it hereunder shall be conclusive absent manifest error.

          (e) If at any time Bank, in its sole and absolute discretion,
determines that: (i) the amount of the LIBOR Rate Loans for periods equal to the
corresponding Interest Periods are not available to Bank in the offshore
currency interbank markets, or (ii) the LIBOR Rate does not accurately reflect
the cost to Bank of lending the LIBOR Rate Loan, then Bank shall promptly give
notice thereof to Borrower, and upon the giving of such notice Bank's obligation
to make the LIBOR Rate Loans shall terminate, unless Bank and the Borrower agree
in writing to a different interest rate Loans shall terminate, unless Bank and
the Borrower agree in writing to a different interest rate applicable to LIBOR
Rate Loans. If it shall become unlawful for Bank to continue to fund or maintain
any Loans, or to perform its obligations hereunder, upon demand by Bank,
Borrower shall prepay the Loans in full with accrued interest thereon and all
other amounts payable by Borrower hereunder (including, without limitation, any
amount payable in connection with such prepayment pursuant to Section 4(a)).

                           ONYX SOFTWARE CORPORATION

          1994 COMBINED INCENTIVE AND NONQUALIFIED STOCK OPTION PLAN
                  AS AMENDED AND RESTATED ON OCTOBER 23, 1998

SECTION 1.  PURPOSE

     The purpose of the ONYX Software Corporation 1994 Combined Incentive and
Nonqualified Stock Option Plan (the "Plan") is to enable ONYX Software
Corporation, a Washington corporation (the "Company"), to attract and retain the
services of people with training, experience and ability and to provide
additional incentive to such persons by granting them an opportunity to
participate in the ownership of the Company.

SECTION 2.  STOCK SUBJECT TO PLAN

     The stock subject to the Plan shall be the Company's common stock, no par
value (the "Common Stock"), presently authorized but unissued or now held or
subsequently acquired by the Company.  Subject to adjustment as provided in
Section 10, the aggregate amount of Common Stock reserved for issuance or
delivery upon exercise of all options granted under the Plan shall not exceed
5,000,000 shares of Common Stock.  If any option granted under the Plan shall
expire or terminate for any reason without having been exercised in full, the
unpurchased shares subject thereto shall thereupon again be available for
purposes of the Plan.

SECTION 3.  ADMINISTRATION

     The Plan shall be administered by the Board of Directors of the Company, in
accordance with the following terms and conditions:

     3.1  GENERAL AUTHORITY

     Subject to the express provisions of the Plan, the Board of Directors shall
have the authority, in its discretion, to determine all matters relating to
options to be granted under the Plan, including the selection of individuals to
be granted options, the number of shares to be subject to each option, the
exercise price, the term, whether such options shall be immediately exercisable
or shall become exercisable in increments over time, and all other terms and
conditions thereof.  Grants under the Plan to persons eligible need not be
identical in any respect, even when made simultaneously.  The Board of Directors
may from time to time adopt rules and regulations relating to the administration
of the Plan.  The interpretation and construction by the Board of Directors of
any terms or provisions of the Plan or any 
<PAGE>
 
option issued hereunder, or of any rule or regulation promulgated in connection
herewith, shall be conclusive and binding on all interested parties. The Board
of Directors, in its sole discretion, may grant incentive stock options
("Incentive Stock Options") as such term is defined in Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), and/or nonqualified
stock options ("Nonqualified Stock Options"). A Nonqualified Stock Option is a
stock option which is not an Incentive Stock Option. The type of option granted,
whether an Incentive Stock Option or a Nonqualified Stock Option shall be
clearly identified by the Board of Directors when granted. The term "option,"
when used in the Plan, should refer to Incentive Stock Options and Nonqualified
Stock Options, collectively.

     3.2  DIRECTORS

     A member of the Board of Directors may be eligible to participate in or
receive or hold options under the Plan; provided, however, that no member of the
Board of Directors shall vote with respect to the granting of an option
hereunder to himself or herself, as the case may be.

     3.3  DELEGATION TO A COMMITTEE

     Notwithstanding the foregoing, the Board of Directors, if it so determines,
may delegate to a committee of the Board of Directors any or all authority for
the administration of the Plan, and thereafter references to the Board of
Directors in the Plan shall be deemed to be references to the committee to the
extent provided in the resolution establishing the committee.

     3.4  PERSONS SUBJECT TO SECTION 16(B)

     Notwithstanding anything in the Plan to the contrary, the Board of
Directors, in its absolute discretion, may bifurcate the Plan so as to restrict,
limit or condition the use of any provision of the Plan to participants who are
officers and directors subject to Section 16(b) of the Securities Exchange Act
of 1934, as amended (the "1934 Act"), without so restricting, limiting or
conditioning the Plan with respect to other participants.

     3.5  REPLACEMENT OF OPTIONS

     The Board of Directors, in its absolute discretion, may grant options
subject to the condition that options previously granted at a higher or lower
exercise price under the Plan be cancelled or exchanged in connection with such
grant.  The number of shares covered by the new options, the exercise price, the
term and the other terms and conditions of the new option, shall be determined
in accordance with the Plan and 

                                       2
<PAGE>
 
may be different from the provisions of the cancelled or exchanged options.
Alternatively, the Board of Directors may, with the agreement of the Optionee,
amend previously granted options to establish the exercise price at the then
current fair market value of the Company's Common Stock, maintaining existing
vesting and expiration dates.

     3.6  LOANS TO OPTIONEES

     The Board of Directors, in its absolute discretion, may provide that the
Company loan to Optionees sufficient funds to exercise any option granted under
the Plan and/or to pay withholding tax due upon exercise of such option.  The
Board of Directors shall have the authority to make such determinations at the
time of grant or exercise and shall establish repayment terms thereof, including
installments, maturity and interest rate; provided, however, that repayment of
any Company loan to the Optionee shall be secured by delivery of a full-recourse
promissory note for the loan amount executed by the Optionee, together with any
other form of security determined by the Board of Directors.  The maximum credit
available is the purchase price, if any, of the Common Stock acquired, plus the
maximum federal and state income and employment liability that may be incurred
in connection with the acquisition.  The amount of any promissory note delivered
in connection with an Incentive Stock Option shall bear interest at a rate
specified by the Board of Directors but in no case less than the rate required
to avoid imputation of interest (taking into account any exceptions to the
imputed interest rules) for federal income tax purposes.

SECTION 4.  ELIGIBILITY

     Options may be granted only to persons who, at the time the option is
granted, are employees, directors, consultants or independent contractors of the
Company or any of its present or future parent or subsidiary corporations (as
those terms are used in Section 422(a)(2) and (d)(1) and Section 424(e) and (f)
of the Code, hereafter a "Parent" or "Subsidiary").  Any individual to whom an
option is granted under the Plan shall be referred to as "Optionee."  Any
Optionee may receive one or more grants of options as the Board of Directors
shall from time to time determine, and such determinations may be different as
to different Optionees and may vary as to different grants.  Optionees who are
not employees will only be eligible to receive Nonqualified Stock Options.  No
Optionee shall be granted options in any calendar year in excess of 40% of the
shares of Common Stock issuable under the Plan pursuant to Section 2, as amended
from time to time.

                                       3

SECTION 5.  TERMS AND CONDITIONS OF OPTIONS

     Options granted under the Plan shall be evidenced by written agreements
which shall contain such terms, conditions, limitations and restrictions as the
Board of Directors shall deem advisable and which are not inconsistent with the
Plan.  Each option granted hereunder shall clearly indicate whether it is an
Incentive Stock Option or a Nonqualified Stock Option.  Notwithstanding the
foregoing, all such options shall include or incorporate by reference the
following terms and conditions:

     5.1  NUMBER OF SHARES

     The maximum number of shares that may be purchased pursuant to the exercise
of each option and the price per share at which such option is exercisable (the
"exercise price") shall be as established by the Board of Directors, provided
that the exercise price of Incentive Stock Options shall not be less than the
fair market value per share of the Common Stock at the time the option is
granted, as determined in good faith by the Board of Directors.  The exercise
price of Nonqualified Stock Options may be greater or less than the fair market
value per share of the Common Stock at the time the option is granted.

     5.2  DURATION OF OPTIONS

     Subject to the restrictions contained in Sections 7 and 9, the term of each
option shall be established by the Board of Directors and, if not so
established, shall be ten years from the date it is granted, but in no event
shall the term of any Incentive Stock Option exceed ten years.

     5.3  EXERCISABILITY

     Each option shall prescribe the installments, if any, in which an option
granted under the Plan shall become exercisable.  The Board of Directors, in its
absolute discretion, may waive or accelerate any installment requirement
contained in outstanding options.  In no case may an option be exercised as to
less than 100 shares at any one time (or the remaining shares covered by the
option if less than 100) during the term of the option.  Only whole shares shall
be issued pursuant to the exercise of any option.

     5.4  INCENTIVE STOCK OPTION

     Any option which is issued as an Incentive Stock Option under the Plan,
shall, notwithstanding any other provisions of the Plan or the option terms to
the contrary, 

                                       4
<PAGE>
 
contain all of the terms, conditions, restrictions, rights and limitations
required to be an Incentive Stock Option, and any provision to the contrary
shall be disregarded.

SECTION 6.  TRANSFERABILITY OF OPTIONS

     Options granted under the Plan and the rights and privileges conferred
hereby may not be transferred, assigned, pledged or hypothecated in any manner
(whether by operation of law or otherwise) other than by will or the applicable
laws of descent and distribution, and shall not be subject to execution,
attachment or similar process.  Upon any attempt to transfer, assign, pledge,
hypothecate or otherwise dispose of any option under the Plan or any right or
privilege conferred hereby, contrary to the provisions hereof, or upon the sale
or levy or any attachment or similar process, such option thereupon shall
terminate and become null and void.  During an Optionee's lifetime, any options
granted under the Plan are personal to him or her and are exercisable solely by
such Optionee.  Notwithstanding the foregoing, and to the extent permitted by
Section 422 of the Code, the Board of Directors, in its sole discretion, may
permit such assignment, transfer and exercisability and may permit an Optionee
to designate a beneficiary who may exercise the option after the Optionee's
death; provided, however, that any option so assigned or transferred shall be
subject to all the same terms and conditions contained in the instrument
evidencing the option.

SECTION 7.  CERTAIN LIMITATIONS REGARDING INCENTIVE STOCK OPTIONS

     The grant of Incentive Stock Options shall be subject to the following
special limitations:

     7.1  LIMITATION ON AMOUNT OF GRANTS

     To the extent that any Optionee is granted Incentive Stock Options that in
the aggregate (together with all other Incentive Stock Options granted by the
Company or any Parents or Subsidiaries) entitle the Optionee to purchase, in any
calendar year during which such options first become exercisable, stock of the
Company, any Parent or any Subsidiary having a fair market value (determined as
of the time such options are granted) which exceeds $100,000, such excess
portion shall be treated as a Nonqualified Stock Option.  No limitation shall
apply to Nonqualified Stock Options.

     7.2  GRANTS TO 10% SHAREHOLDERS

     Incentive Stock Options may be granted to a person owning more than 10% of
the total combined voting power of all classes of stock of the Company and any
Parent or Subsidiary only if (i) the exercise price is at least 110% of the fair
market 

                                       5
<PAGE>
 
value of the stock at the time of grant and (ii) the option is not exercisable
after the expiration of five years from the date of grant.

SECTION 8.  EXERCISE OF OPTIONS

     Options shall be exercised in accordance with the following terms and
conditions:

     8.1  PROCEDURE

     Options shall be exercised by delivery to the Company of written notice of
the number of shares with respect to which the option is exercised.

     8.2  PAYMENT

     (i)  For options granted on or after October 23, 1998, the exercise price
for shares purchased under an option shall be paid in full to the Company by
delivery of consideration equal to the product of the option exercise price and
the number of shares purchased.  Such consideration must be paid in cash or by
check or, unless the Board of Directors in its sole discretion determines
otherwise, either at the time the option is granted or at any time before it is
exercised, a combination of cash and/or check (if any) and one or both of the
following alternative forms:  (a) tendering (either actually or, if and so long
as the Common Stock is registered under Section 12(b) or 12(g) of the 1934 Act,
by attestation) Common Stock already owned by the Optionee for at least six
months (or any shorter period necessary to avoid a charge to the Company's
earnings for financial reporting purposes) having a fair market value on the day
prior to the exercise date equal to the aggregate option exercise price; or (b)
if and so long as the Common Stock is registered under Section 12(b) or 12(g) of
the 1934 Act, delivery of a properly executed exercise notice, together with
irrevocable instructions, to (1) a brokerage firm designated by the Company to
deliver promptly to the Company the aggregate amount of sale or loan proceeds to
pay the option exercise price and any withholding tax obligations that may arise
in connection with the exercise and (2) the Company to deliver the certificates
for such purchased shares directly to such brokerage firm, all in accordance
with the regulations of the Federal Reserve Board.  In addition, to the extent
permitted by the Board of Directors in its sole discretion, the price for shares
purchased under an option may be paid, either singly or in combination with one
or more of the alternative forms of payment authorized by this subsection 8.2 by
(y) a promissory note delivered pursuant to subsection 3.6 or (z) such other
consideration as the Board of Directors may permit.

     (ii) For options granted before October 23, 1998, payment of the option
price shall be made in full within three business days of the notice of exercise
of the 

                                       6
<PAGE>
 
option and shall be in cash or bank-certified or cashier's checks, or personal
check if permitted by the Board of Directors. To the extent permitted by
applicable laws and regulations (including, but not limited to, federal tax and
securities laws and regulations), an option may be exercised by delivery of
shares of Common Stock of the Company held by the Optionee having a fair market
value equal to the exercise price, such fair market value to be determined in
good faith by the Board of Directors. Such payment in stock may occur in the
context of a single exercise of an option or successive and simultaneous
exercises, sometimes referred to as "pyramiding," which provides that, rather
than physically exchanging certificates for a series of exercises, bookkeeping
entries will be made pursuant to which the Optionee is permitted to retain his
existing stock certificate and a new stock certificate is issued for the net
shares.

     If the Company's Common Stock is registered under the 1934 Act, and if
permitted by the Board of Directors, and to the extent permitted by applicable
laws and regulations (including, but not limited to, federal tax and securities
laws and regulations), an option also may be exercised by delivery of a properly
executed exercise notice together with irrevocable instructions to a broker to
promptly deliver to the Company the amount of sale or loan proceeds to pay the
exercise price.

     8.3  FEDERAL WITHHOLDING TAX REQUIREMENTS

     Upon exercise of an option, the Optionee shall, upon notification of the
amount due and prior to or concurrently with the delivery of the certificates
representing the shares, pay to the Company amounts necessary to satisfy
applicable federal, state and local withholding tax requirements or shall
otherwise make arrangements satisfactory to the Company for such requirements.
Such arrangements may include payment of the appropriate withholding tax in
shares of Common Stock having a fair market value equal to such withholding tax,
either through delivery of shares held by the Optionee or by reduction in the
number of shares to be delivered to the Optionee upon exercise of such option.

SECTION 9.  TERMINATION OF EMPLOYMENT, DISABILITY AND DEATH

     9.1  GENERAL

     If the employment of the Optionee by the Company, a Parent or a Subsidiary
shall terminate by retirement or for any reason other than death, disability or
cause as hereinafter provided, the option may be exercised by the Optionee at
any time prior to the expiration of three months after the date of such
termination of employment (unless by its terms the option sooner terminates or
expires), but only if, and to the 

                                       7
<PAGE>
 
extent, the Optionee was entitled to exercise the option at the date of such
termination.

     9.2  DISABILITY

     If the employment of the Optionee by the Company, a Parent or a Subsidiary
is terminated because of the Optionee's disability (as herein defined), the
option may be exercised by the Optionee at any time prior to the expiration of
one year after the date of such termination (unless by its terms the option
sooner terminates or expires), but only if, and to the extent, the Optionee was
entitled to exercise the option at the date of such termination.  For purposes
of this section, an Optionee will be considered to be disabled if the Optionee
is unable to engage in any substantial gainful activity by reason of any
medically determinable mental or physical impairment which can be expected to
result in death or which has lasted or can be expected to last a continuous
period of not less than 12 months.

     9.3  DEATH

     In the event of the death of an Optionee while in the employ of the
Company, a Parent or a Subsidiary, the option shall be exercisable on or prior
to the expiration of one year after the date of such death (unless by its terms
the option sooner terminates and expires), but only if and to the extent the
Optionee was entitled to exercise the option at the date of such death and only
by the Optionee's personal representative if then subject to administration as
part of the Optionee's estate, designated beneficiary, or by the person or
persons to whom such Optionee's rights under the option shall have passed by the
Optionee's will or by the applicable laws of descent and distribution.

     9.4  TERMINATION FOR CAUSE

     If the Optionee's employment with the Company, a Parent or a Subsidiary is
terminated for cause, any option granted hereunder shall automatically terminate
as of the first advice or discussion thereof, and such Optionee shall thereupon
have no right to purchase any shares pursuant to such option.  "Termination for
Cause" shall mean dismissal for dishonesty, conviction or confession of a crime
punishable by law (except minor violations), intoxication while at work, fraud,
misconduct or disclosure of confidential information, in each case as determined
by the Board of Directors, and its determination shall be conclusive and
binding.

                                       8
<PAGE>
 
     9.5  WAIVER OR EXTENSION OF TIME PERIODS

     The Board of Directors shall have the authority, prior to or within the
times specified in this Section 9 for the exercise of any such option, to extend
such time period or waive in its entirety any such time period to the extent
that such time period expires prior to the expiration of the term of such
option.  In addition, the Board of Directors may grant, pursuant to a specific
resolution adopted at the time of grant, modify or eliminate the time periods
specified in this Section 9.  If an Optionee holding an Incentive Stock Option
exercises such option, by permission, after the expiration of the time period
specified in this Section 9, the option will no longer be treated as an
Incentive Stock Option under the Code and shall automatically be converted into
a Nonqualified Stock Option.

     9.6  TERMINATION OF OPTIONS

     To the extent that the option of any deceased Optionee or of any Optionee
whose employment is terminated shall not have been exercised within the limited
periods prescribed in this Section 9, all further rights to purchase shares
pursuant to such option shall cease and terminate at the expiration of such
period.  No Incentive Stock Option may be exercised after the expiration of ten
years from the date such option is granted, notwithstanding any provision to the
contrary.

     9.7  NONEMPLOYEE OPTIONEES

     Options granted to Optionees who are not employees of the Company, a Parent
or a Subsidiary at the time of grant shall not be subject to the provisions of
this Section 9, except as specifically provided in the option.

SECTION 10.  OPTION ADJUSTMENTS

     10.1 ADJUSTMENTS UPON CHANGES IN CAPITALIZATION

     The aggregate number and class of shares on which options may be granted
under the Plan, the number and class of shares covered by each outstanding
option and the exercise price per share thereof (but not the total price), and
all such options, shall each be proportionately adjusted for any increase or
decrease in the number of issued shares of Common Stock resulting from a split-
up or consolidation of shares or any like capital adjustment, or the payment of
any stock dividend, or any other increase or decrease in the number of shares of
Common Stock without the receipt of consideration by the Company.

                                       9
<PAGE>
 
     10.2  EFFECT OF CERTAIN TRANSACTIONS

     Except as provided in subsection 10.3, upon a merger, consolidation,
acquisition of property or stock, separation, reorganization or liquidation of
the Company, as a result of which the shareholders of the Company receive cash,
stock or other property in exchange for their shares of Common Stock, any option
granted hereunder shall terminate, but, provided that the Optionee shall have
the right immediately prior to any such merger, consolidation, acquisition of
property or stock, separation, reorganization or liquidation to exercise his or
her option in whole or in part whether or not the vesting requirements set forth
in the option agreement have been satisfied.

     10.3  CONVERSION OF OPTIONS ON STOCK FOR STOCK EXCHANGE

     If the shareholders of the Company receive capital stock of another
corporation ("Exchange Stock") in exchange for their shares of Common Stock in
any transaction involving a merger, consolidation, acquisition of property or
stock, separation or reorganization, all options granted hereunder shall
terminate in accordance with the provision of subsection 10.2 unless the Board
of Directors and the corporation issuing the Exchange Stock, in their sole and
arbitrary discretion and subject to any required action by the shareholders of
the Company and such corporation, agree that all such options granted hereunder
are converted into options to purchase shares of Exchange Stock.  The amount and
price of such options shall be determined by adjusting the amount and price of
the options granted hereunder in the same proportion as used for determining the
number of shares of Exchange Stock the holders of the Common Stock receive in
such merger, consolidation, acquisition of property or stock, separation or
reorganization.  The vesting schedule set forth in the option agreement shall
continue to apply to the options granted for the Exchange Stock.

     10.4  FRACTIONAL SHARES

     In the event of any adjustment in the number of shares covered by an
option, any fractional shares resulting from such adjustment shall be
disregarded and each such option shall cover only the number of full shares
resulting from such adjustment.

     10.5  DETERMINATION OF BOARD OF DIRECTORS TO BE FINAL

     All such adjustments shall be made by the Board of Directors and its
determination as to what adjustments shall be made, and the extent thereof,
shall be final, binding and conclusive.

                                       10
<PAGE>
 
SECTION 11.  SECURITIES REGULATIONS

     11.1  COMPLIANCE

     Shares shall not be issued with respect to an option granted under the Plan
unless the exercise of such option and the issuance and delivery of such shares
pursuant thereto shall comply with all relevant provisions of law, including,
without limitation, any applicable state securities laws, the Securities Act of
1933, as amended, the 1934 Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the shares may
then be listed, and shall further be subject to the approval of counsel for the
Company with respect to such compliance.  Inability of the Company to obtain
from any regulatory body having jurisdiction, the authority deemed by the
Company's counsel to be necessary for the lawful issuance and sale of any shares
hereunder, shall relieve the Company of any liability in respect of the
nonissuance or sale of such shares as to which such requisite authority shall
not have been obtained.

     11.2  REPRESENTATIONS BY OPTIONEE

     As a condition to the exercise of an option, the Company may require the
Optionee to represent and warrant at the time of any such exercise that the
shares are being purchased only for investment and without any present intention
to sell or distribute such shares, if, in the opinion of counsel for the
Company, such representation is required by any relevant provision of the laws
referred to in subsection 11.1.  At the option of the Company, a stop transfer
order against any shares of stock may be placed on the official stock books and
records of the Company, and a legend indicating that the stock may not be
pledged, sold or otherwise transferred unless an opinion of counsel was provided
(concurred in by counsel for the Company) stating that such transfer is not in
violation of any applicable law or regulation, may be stamped on the stock
certificate in order to assure exemption from registration.  The Board of
Directors may also require such other action or agreement by the Optionees as
may from time to time be necessary to comply with the federal and state
securities laws.  This provision shall not obligate the Company to undertake
registration of options or stock hereunder.

SECTION 12.  EMPLOYMENT RIGHTS

     Nothing in the Plan or any option or right granted pursuant hereto shall
confer upon any Optionee any right to be continued in the employment of the
Company, a Parent or any Subsidiary of the company or to remain a director, or
to interfere in any way with the right of the Company, a Parent or any
Subsidiary, in its sole discretion, 

                                       11
<PAGE>
 
to terminate such Optionee's employment at any time or to remove the Optionee as
a director at any time.

SECTION 13.  AMENDMENT AND TERMINATION

     13.1  ACTION BY SHAREHOLDERS

     The Plan may be terminated, modified or amended by the shareholders of the
Company.

     13.2  ACTION BY BOARD OF DIRECTORS

     The Board of Directors may also terminate the Plan, or modify or amend the
Plan in such respects as it shall deem advisable in order to conform to any
changes in law or regulation applicable thereto, or in other respects; provided,
however, that the Board of Directors may not, without further approval by the
shareholders of the Company:

           (i)   Increase the number of shares in the aggregate which may be
sold pursuant to options granted under the Plan;

           (ii)  Increase the period during which options may be granted or
exercised; or

           (iii) Change the terms of the Plan which causes the Plan to lose its
qualification as an incentive stock option plan under Section 422 of the Code.

     No termination, suspension or amendment of the Plan may, without the
consent of each Optionee to whom any option shall theretofore have been granted,
adversely affect the rights of such Optionees under such options.

     13.3  AUTOMATIC TERMINATION

     Unless the Plan shall theretofore have been terminated as herein provided,
the Plan shall terminate ten years from the earlier of:  (i) the date on which
the Plan is adopted or (ii) the date on which the Plan is approved by the
shareholders of the Company.  No option may be granted after such termination,
or during any suspension of the Plan.  The amendment or termination of the Plan
shall not, without the consent of the Optionee, alter or impair any rights or
obligations under any option theretofore granted under the Plan.

                                       12
<PAGE>
 
SECTION 14.  EFFECTIVE DATE OF THE PLAN

     The Plan shall become effective on the date of its adoption by the Board of
Directors of the Company and options may be granted immediately thereafter but
no option may be exercised under the Plan unless and until the Plan shall have
been approved by the shareholders within 12 months after the date of adoption of
the Plan by the Board of Directors.  If such approval is not obtained within
such period the Plan and any options granted thereunder shall be null and void.

SECTION 15.  GENERAL

     15.1  NO RIGHTS AS A SHAREHOLDER
           --------------------------

     No option shall entitle the Optionee to any dividend, voting or other right
of a shareholder unless and until the date of issuance under the Plan of the
shares that are the subject of such option, free of all applicable restrictions.

     15.2  NO TRUST OR FUND
           ----------------

     The Plan is intended to constitute an "unfunded" plan.  Nothing contained
herein shall require the Company to segregate any monies or other property, or
shares of Common Stock, or to create any trusts, or to make any special deposits
for any immediate or deferred amounts payable to any Optionee, and no Optionee
shall have any rights that are greater than those of a general unsecured
creditor of the Company.

     15.3  SEVERABILITY
           ------------

     If any provision of the Plan or any option is determined to be invalid,
illegal or unenforceable in any jurisdiction, or as to any person, or would
disqualify the Plan or any option under any law deemed applicable by the Board
of Directors, such provision shall be construed or deemed amended to conform to
applicable laws, or, if it cannot be so construed or deemed amended without, in

Combined Incentive and Nonqualified Stock Option Plan (the "Predecessor Plan")
as of the Effective Date; and

cease to be subject to the Award (other than by reason of exercise or payment of
the Award to the extent it is exercised for or settled in shares) shall again be
available for issuance in connection with future grants of Awards under the
Plan.

                            SECTION 5.  ELIGIBILITY

6.2  ACQUIRED COMPANY AWARDS

     Notwithstanding anything in the Plan to the contrary, the Plan
Administrator may grant Awards under the Plan in substitution for awards issued
under other plans, or assume under the Plan awards issued under other plans, if
the other plans are or were plans of other acquired entities ("Acquired
Entities") (or the parent of the Acquired Entity) and the new Award is
substituted, or the old award is assumed, by reason of a merger, consolidation,
acquisition of property or of stock, reorganization or liquidation (the
"Acquisition Transaction").  In the event that a written agreement pursuant to
which the Acquisition Transaction is completed is approved by the Board and said
agreement sets forth the terms and conditions of the substitution for or
assumption of outstanding awards of the Acquired Entity, said terms and
conditions shall be deemed to be the action of the Plan

Administrator without any further action by the Plan Administrator, except as

Option may be exercised from time to time by written notice to the Company, in
accordance with procedures established by the Plan Administrator, setting forth
the number of shares with respect to which the Option is being exercised and

<PAGE>
 
7.5  PAYMENT OF EXERCISE PRICE

     The exercise price for shares purchased under an Option shall be paid in
full to the Company by delivery of consideration equal to the product of the
Option exercise price and the number of shares purchased.  Such consideration
must be paid in cash or by check or, unless the Plan Administrator in its sole
discretion determines otherwise, either at the time the Option is granted or at
any time before it is exercised, a combination of cash and/or check (if any) and
one or both of the following alternative forms:  (a) tendering (either actually
or, if and so long as the Common Stock is registered under Section 12(b) or
12(g) of the Exchange Act, by attestation) Common Stock already owned by the
Holder for at least six months (or any shorter period necessary to avoid a
charge to the Company's earnings for financial reporting purposes) having a Fair
Market Value on the day prior to the exercise date equal to the aggregate Option
exercise price; or (b) if and so long as the Common Stock is registered under
Section 12(b) or 12(g) of the Exchange Act, delivery of a properly executed
exercise notice, together with irrevocable instructions, to (i) a brokerage firm
designated by the Company to deliver promptly to the Company the aggregate
amount of sale or loan proceeds to pay the Option exercise price and any
withholding tax obligations that may arise in connection with the exercise and
(ii) the Company to deliver the certificates for such purchased shares directly
to such brokerage firm, all in accordance with the regulations of the Federal
Reserve Board.  In addition, to the extent permitted by the Plan Administrator
in its sole discretion, the price for shares purchased under an Option may be
paid, either singly or in combination with one or more of the alternative forms
of payment authorized by this Section 7.5, by (y) a promissory note delivered
pursuant to Section 13; or (z) such other consideration as the Plan
Administrator may permit.

7.6  POST-TERMINATION EXERCISES

     The Plan Administrator shall establish and set forth in each instrument
that evidences an Option whether the Option will continue to be exercisable, and
the terms and conditions of such exercise, if a Holder ceases to be employed by,
or to provide services to, the Company or its Subsidiaries, which provisions may
be waived or modified by the Plan Administrator at any time.  If not so
established in the instrument evidencing the Option, the Option will be
exercisable according to the following terms and conditions, which may be waived
or modified by the Plan Administrator at any time.

     In case of termination of the Holder's employment or services other than by
reason of death or Cause, the Option shall be exercisable, to the extent of the
number of shares purchasable by the Holder at the date of such termination, only
(a) within one year if the termination of the Holder's employment or services is
coincident with Disability or (b) within three months after the date the Holder
ceases to be an employee, director, officer, consultant, agent, advisor or
independent contractor of the Company or a Subsidiary if termination of the
Holder's employment or services is for any reason other than Disability, but in
no event later than the remaining term of the Option.  Any Option exercisable at
the time of the Holder's death may be exercised, to the extent of the number of
shares purchasable by the Holder at the date of the Holder's death, by the
personal representative of the Holder's estate, the person(s) to whom the
Holder's rights under the Award have passed by will or the applicable laws of
descent and distribution or the beneficiary designated pursuant to Section 10,
at any time or from time to time within one year after the date 

                                      -8-
<PAGE>
 
of death, but in no event later than the remaining term of the Option. Any
portion of an Option that is not exercisable on the date of termination of the
Holder's employment or services shall terminate on such date, unless the Plan
Administrator determines otherwise. In case of termination of the Holder's
employment or services for Cause, the Option shall automatically terminate upon
first notification to the Holder of such termination, unless the Plan
Administrator determines otherwise. If a Holder's employment or services with
the Company are suspended pending an investigation of whether the Holder shall
be terminated for Cause, all the Holder's rights under any Option likewise shall
be suspended during the period of investigation.

     A transfer of employment or services between or among the Company and its
Subsidiaries shall not be considered a termination of employment or services.
The effect of a Company-approved leave of absence on the terms and conditions of
an Option shall be determined by the Plan Administrator, in its sole discretion.

                 SECTION 8.  INCENTIVE STOCK OPTION LIMITATIONS

     To the extent required by Section 422 of the Code, Incentive Stock Options
shall be subject to the following additional terms and conditions:

8.1  DOLLAR LIMITATION

     To the extent the aggregate Fair Market Value (determined as of the Grant
Date) of Common Stock with respect to which Incentive Stock Options are
exercisable by a Holder for the first time during any calendar year (under the
Plan and all other stock option plans of the Company) exceeds $100,000, such
portion in excess of $100,000 shall be treated as a Nonqualified Stock Option.
In the event the Holder holds two or more such Options that become exercisable
for the first time in the same calendar year, such limitation shall be applied
on the basis of the order in which such Options are granted.

8.2  10% SHAREHOLDERS

     If an individual owns more than 10% of the total voting power of all
classes of the Company's stock, then the exercise price per share of an
Incentive Stock Option shall not be less than 110% of the Fair Market Value of
the Common Stock on the Grant Date and the Option term shall not exceed five
years.  The determination of 10% ownership shall be made in accordance with
Section 422 of the Code.

8.3  ELIGIBLE EMPLOYEES

     Individuals who are not employees of the Company or one of its parent
corporations or subsidiary corporations may not be granted Incentive Stock
Options.  For purposes of this Section 8.3, "parent corporation" and "subsidiary
corporation" shall have the meanings attributed to those terms for purposes of
Section 422 of the Code.

8.4  TERM

     The term of an Incentive Stock Option shall not exceed 10 years.

                                      -9-
<PAGE>
 
8.5  EXERCISABILITY

     To qualify for Incentive Stock Option tax treatment, an Option designated
as an Incentive Stock Option must be exercised within three months after
termination of employment for reasons other than death, except that, in the case
of termination of employment due to total disability, such Option must be
exercised within one year after such termination.  Employment shall not be
deemed to continue beyond the first 90 days of a leave of absence unless the
Holder's reemployment rights are guaranteed by statute or contract.  For
purposes of this Section 8.5, "total disability" shall mean a mental or physical
impairment of the Holder that is expected to result in death or that has lasted
or is expected to last for a continuous period of 12 months or more and that
causes the Holder to be unable, in the opinion of the Company and two
independent physicians, to perform his or her duties for the Company and to be
engaged in any substantial gainful activity.  Total disability shall be deemed
to have occurred on the first day after the Company and the two independent
physicians have furnished their opinion of total disability to the Plan
Administrator.

8.6  TAXATION OF INCENTIVE STOCK OPTIONS

     In order to obtain certain tax benefits afforded to Incentive Stock Options
under Section 422 of the Code, the Holder must hold the shares issued upon the
exercise of an Incentive Stock Option for two years after the Grant Date of the
Incentive Stock Option and one year from the date of exercise.  A Holder may be
subject to the alternative minimum tax at the time of exercise of an Incentive
Stock Option.  The Plan Administrator may require a Holder to give the Company
prompt notice of any disposition of shares acquired by the exercise of an
Incentive Stock Option prior to the expiration of such holding periods.

8.7  Promissory Notes

     The amount of any promissory note delivered pursuant to Section 13 in
connection with an Incentive Stock Option shall bear interest at a rate
specified by the Plan Administrator but in no case less than the rate required
to avoid imputation of interest (taking into account any exceptions to the
imputed interest rules) for federal income tax purposes.

                           SECTION 9.  STOCK AWARDS

9.1  GRANT OF STOCK AWARDS

     The Plan Administrator is authorized to make Awards of Common Stock on such
terms and conditions and subject to such restrictions, if any (which may be
based on continuous service with the Company or the achievement of performance
goals), as the Plan Administrator shall determine, in its sole discretion, which
terms, conditions and restrictions shall be set forth in the instrument
evidencing the Award.  The terms, conditions and restrictions that the Plan
Administrator shall have the power to determine shall include, without
limitation, the manner in which shares subject to Stock Awards are held during
the periods they are subject to restrictions and the circumstances under which
forfeiture of Restricted Stock shall occur by reason of termination of the
Holder's services.

                                      -10-
<PAGE>
 
9.2  ISSUANCE OF SHARES

     Upon the satisfaction of any terms, conditions and restrictions prescribed
in respect to a Stock Award, or upon the Holder's release from any terms,
conditions and restrictions of a Stock Award, as determined by the Plan
Administrator, the Company shall release, as soon as practicable, to the Holder
or, in the case of the Holder's death, to the personal representative of the
Holder's estate or as the appropriate court directs, the appropriate number of
shares of Common Stock.

9.3  WAIVER OF RESTRICTIONS

     Notwithstanding any other provisions of the Plan, the Plan Administrator
may, in its sole discretion, waive the forfeiture period and any other terms,
conditions or restrictions on any Restricted Stock under such circumstances and
subject to such terms and conditions as the Plan Administrator shall deem
appropriate.

                          SECTION 10.  ASSIGNABILITY

     No Option granted under the Plan may be assigned or transferred by the
Holder other than by will or by the applicable laws of descent and distribution,
and, during the Holder's lifetime, such Awards may be exercised only by the
Holder.  Notwithstanding the foregoing, and to the extent permitted by Section
422 of the Code, the Plan Administrator, in its sole discretion, may permit such
assignment, transfer and exercisability and may permit a Holder of such Awards
to designate a beneficiary who may exercise the Award or receive compensation
under the Award after the Holder's death; provided, however, that any Award so
assigned or transferred shall be subject to all the same terms and conditions
contained in the instrument evidencing the Award.

                           SECTION 11.  ADJUSTMENTS

11.1 ADJUSTMENT OF SHARES

     In the event that, at any time or from time to time, a stock dividend,
stock split, spin-off, combination or exchange of shares, recapitalization,
merger, consolidation, distribution to shareholders other than a normal cash
dividend, or other change in the Company's corporate or capital structure
results in (a) the outstanding shares, or any securities exchanged therefor or
received in their place, being exchanged for a different number or class of
securities of the Company or of any other corporation or (b) new, different or
additional securities of the Company or of any other corporation being received
by the holders of shares of Common Stock of the Company, then the Plan
Administrator shall make proportional adjustments in (i) the maximum number and
kind of securities subject to the Plan as set forth in Section 4.1 and (ii) the
number and kind of securities that are subject to any outstanding Award and the
per share price of such securities, without any change in the aggregate price to
be paid therefor.  The determination by the Plan Administrator as to the terms
of any of the foregoing adjustments shall be conclusive and binding.

                                      -11-
<PAGE>
 
11.2 CORPORATE TRANSACTION

     Except as otherwise provided in the instrument that evidences the Award, in
the event of any Corporate Transaction, each Award that is at the time
outstanding shall automatically accelerate so that each such Award shall,
immediately prior to the specified effective date for the Corporate Transaction,
become 100% vested and exercisable, except that such acceleration will not occur
if, in the opinion of the Company's outside accountants, it would render
unavailable "pooling of interest" accounting for a Corporate Transaction that
would otherwise qualify for such accounting treatment.  Such Award shall not so
accelerate, however, if and to the extent that such Award is, in connection with
the Corporate Transaction, either to be assumed by the successor corporation or
parent thereof (the "Successor Corporation") or to be replaced with a comparable
award for the purchase of shares of the capital stock of the Successor
Corporation.  The determination of Award comparability shall be made by the Plan
Administrator, and its determination shall be conclusive and binding.  All such
Awards shall terminate and cease to remain outstanding immediately following the
consummation of the Corporate Transaction, except to the extent assumed by the
Successor Corporation.  Any such Awards that are assumed or replaced in the
Corporate Transaction and do not otherwise accelerate at that time shall be
accelerated in the event that the Holder's employment or services should
subsequently terminate within two years following such Corporate Transaction,
unless such employment or services are terminated by the Successor Corporation
for Cause or by the Holder voluntarily without Good Reason.

11.3 FURTHER ADJUSTMENT OF AWARDS

     Subject to Section 11.2, the Plan Administrator shall have the discretion,
exercisable at any time before a sale, merger, consolidation, reorganization,
liquidation or change in control of the Company, as defined by the Plan
Administrator, to take such further action as it determines to be necessary or
advisable, and fair and equitable to Holders, with respect to Awards.  Such
authorized action may include (but shall not be limited to) establishing,
amending or waiving the type, terms, conditions or duration of, or restrictions
on, Awards so as to provide for earlier, later, extended or additional time for
exercise, lifting restrictions and other modifications, and the Plan
Administrator may take such actions with respect to all Holders, to certain
categories of Holders or only to individual Holders.  The Plan Administrator may
take such action before or after granting Awards to which the action relates and
before or after any public announcement with respect to such sale, merger,
consolidation, reorganization, liquidation or change in control that is the
reason for such action.

11.4 LIMITATIONS

     The grant of Awards will in no way affect the Company's right to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

                                      -12-
<PAGE>
 
                           SECTION 12.  WITHHOLDING

     The Company may require the Holder to pay to the Company the amount of any
withholding taxes that the Company is required to withhold with respect to the
grant, vesting or exercise of any Award.  Subject to the Plan and applicable
law, the Plan Administrator may, in its sole discretion, permit the Holder to
satisfy withholding obligations, in whole or in part, by paying cash, by
electing to have the Company withhold shares of Common Stock or by transferring
shares of Common Stock to the Company, in such amounts as are equivalent to the
Fair Market Value of the withholding obligation.  The Company shall have the
right to withhold from any Award or any shares of Common Stock issuable pursuant
to an Award or from any cash amounts otherwise due or to become due from the
Company to the Holder an amount equal to such taxes.  The Company may also
deduct from any Award any other amounts due from the Holder to the Company or a
Subsidiary.

         SECTION 13.  LOANS, INSTALLMENT PAYMENTS AND LOAN GUARANTEES

     To assist a Holder (including a Holder who is an officer or a director of
the Company) in acquiring shares of Common Stock pursuant to an Award granted
under the Plan, the Plan Administrator, in its sole discretion, may authorize,
either at the Grant Date or at any time before the acquisition of Common Stock
pursuant to the Award, (a) the extension of a loan to the Holder by the Company,
(b) the payment by the Holder of the purchase price, if any, of the Common Stock
in installments, or (c) the guarantee by the Company of a loan obtained by the
Holder from a third party.  The terms of any loans, installment payments or loan
guarantees, including the interest rate and terms of and security for repayment,
will be subject to the Plan Administrator's discretion.  Loans, installment
payments and loan guarantees may be granted with or without security.  The
maximum credit available is the purchase price, if any, of the Common Stock
acquired, plus the maximum federal and state income and employment tax liability
that may be incurred in connection with the acquisition.

               SECTION 14.  REPURCHASE AND FIRST REFUSAL RIGHTS

14.1 REPURCHASE RIGHTS

     The Plan Administrator shall have the discretion to authorize the issuance
of unvested shares of Common Stock pursuant to the exercise of an Option.
Should the Holder cease to be employed by or provide services to the Company,
then all shares of Common Stock issued upon exercise of an Option which are
unvested at the time of cessation of employment or services shall be subject to
repurchase at the exercise price paid for such shares.  The terms and conditions
upon which such repurchase right shall be exercisable (including the period and
procedure for exercise) shall be established by the Plan Administrator and set
forth in the agreement evidencing such right.

     All of the Company's outstanding repurchase rights under this Section 14.1
are assignable by the Company at any time.  Such rights shall automatically
terminate, and all shares subject to such terminated rights shall immediately
vest in full, upon the occurrence of a Corporate 

                                      -13-
<PAGE>
 
Transaction, except to the extent: (i) any such repurchase right is expressly
assigned to the Successor Corporation in connection with the Corporate
Transaction or (ii) such termination is precluded by other limitations imposed
by the Plan Administrator at the time the repurchase right is issued.

     The Plan Administrator shall have the discretionary authority, exercisable
either before or after the Holder's cessation of employment or service, to
cancel the Company's outstanding repurchase rights with respect to one or more
shares purchased or purchasable by the Holder under an Option and thereby
accelerate the vesting of such shares in whole or in part at any time.

14.2 FIRST REFUSAL RIGHTS

     Until the date on which the initial registration of the Common Stock under
Section 12(b) or 12(g) of the Exchange Act first becomes effective, the Company
shall have the right of first refusal with respect to any proposed sale or other
disposition by the Holder of any shares of Common Stock issued pursuant to an
Award granted under the Plan.  Such right of first refusal shall be exercisable
in accordance with the terms and conditions established by the Plan
Administrator and set forth in the agreement evidencing such right.

                         SECTION 15.  MARKET STANDOFF

     In connection with any underwritten public offering by the Company of its
equity securities pursuant to an effective registration statement filed under
the Securities Act, including the Company's initial public offering, a person
shall not sell, make any short sale of, loan, hypothecate, pledge, grant any
option for the purchase of, or otherwise dispose or transfer for value or
otherwise agree to engage in any of the foregoing transactions with respect to,
any shares issued pursuant to an Award granted under the Plan without the prior
written consent of the Company or its underwriters.  Such limitations shall be
in effect for such period of time as may be requested by the Company or such
underwriters and agreed to by the Company's officers and directors with respect
to their shares; provided, however, that in no event shall such period exceed
180 days.  The limitations of this paragraph shall in all events terminate two
years after the effective date of the Company's initial public offering.
Holders of shares issued pursuant to an Award granted under the Plan shall be
subject to the market standoff provisions of this paragraph only if the officers
and directors of the Company are also subject to similar arrangements.

     In the event of any stock split, stock dividend, recapitalization,
combination of shares, exchange of shares or other change affecting the
Company's outstanding Common Stock effected as a class without the Company's
receipt of consideration, then any new, substituted or additional securities
distributed with respect to the purchased shares shall be immediately subject to
the provisions of this Section 15, to the same extent the purchased shares are
at such time covered by such provisions.

     In order to enforce the limitations of this Section 15, the Company may
impose stop-transfer instructions with respect to the purchased shares until the
end of the applicable standoff period.

                SECTION 16.  AMENDMENT AND TERMINATION OF PLAN

16.1 AMENDMENT OF PLAN

     The Plan may be amended only by the Board in such respects as it shall deem
advisable; however, to the extent required for compliance with Section 422 of
the Code or any applicable law or regulation, shareholder approval will be
required for any amendment that will (a) increase the total number of shares as
to which Options may be granted under the Plan or that may be issued as Stock
Awards, (b) modify the class of persons eligible to receive Options, or (c)
otherwise require shareholder approval under any applicable law or regulation.

16.2 TERMINATION OF PLAN

     The Board may suspend or terminate the Plan at any time.  Unless sooner
terminated as provided herein, the Plan shall terminate 10 years after the
earlier of the Plan's adoption by the Board and approval by the shareholders.

16.3 CONSENT OF HOLDER

     The amendment or termination of the Plan shall not, without the consent of
the Holder of any Award under the Plan, impair or diminish any rights or
obligations under any Award theretofore granted under the Plan.  Any change or
adjustment to an outstanding Incentive Stock Option shall not, without the
consent of the Holder, be made in a manner so as to constitute a "modification"
that would cause such Incentive Stock Option to fail to continue to qualify as
an Incentive Stock Option.

                              SECTION 17.  GENERAL

17.1 AWARD AGREEMENTS

     Awards granted under the Plan shall be evidenced by a written agreement
that shall contain such terms, conditions, limitations and restrictions as the
Plan Administrator shall deem advisable and that are not inconsistent with the
Plan.

17.2 CONTINUED EMPLOYMENT OR SERVICES; RIGHTS IN AWARDS

     None of the Plan, participation in the Plan or any action of the Plan
Administrator taken under the Plan shall be construed as giving any person any
right to be retained in the employ of the Company or limit the Company's right
to terminate the employment or services of any person.

17.3 REGISTRATION

     The Company shall be under no obligation to any Holder to register for
offering or resale or to qualify for exemption under the Securities Act, or to
register or qualify under state securities laws, any shares of Common Stock,
security or interest in a security paid or issued under, or created by, the
Plan, or to continue in effect any such registrations or qualifications if made.
The Company may issue certificates for shares with such legends and subject to
such restrictions on 

                                      -15-
<PAGE>
 
transfer and stop-transfer instructions as counsel for the Company deems
necessary or desirable for compliance by the Company with federal and state
securities laws.

     Inability of the Company to obtain, from any regulatory body having
jurisdiction, the authority deemed by the Company's counsel to be necessary for
the lawful issuance and sale of any shares hereunder or the unavailability of an
exemption from registration for the issuance and sale of any shares hereunder
shall relieve the Company of any liability in respect of the nonissuance or sale
of such shares as to which such requisite authority shall not have been
obtained.

     As a condition to the exercise of an Option or any other receipt of Common
Stock pursuant to an Award under the Plan, the Company may require the Holder to
represent and warrant at the time of any such exercise or receipt that such
shares are being purchased or received only for the Holder's own account and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any
relevant provision of the aforementioned laws.  At the option of the Company, a
stop-transfer order against any such shares may be placed on the official stock
books and records of the Company, and a legend indicating that such shares may
not be pledged, sold or otherwise transferred, unless an opinion of counsel is
provided (concurred in by counsel for the Company) stating that such transfer is
not in violation of any applicable law or regulation, may be stamped on stock
certificates to ensure exemption from registration.  The Plan Administrator may
also require such other action or agreement by the Holder as may from time to
time be necessary to comply with the federal and state securities laws.

17.4 NO RIGHTS AS A SHAREHOLDER

     No Option shall entitle the Holder to any cash dividend, voting or other
right of a shareholder unless and until the date of issuance under the Plan of
the shares that are the subject of such Option, free of all applicable
restrictions.

17.5 COMPLIANCE WITH LAWS AND REGULATIONS

     Notwithstanding anything in the Plan to the contrary, the Board, in its
sole discretion, may bifurcate the Plan so as to restrict, limit or condition
the use of any provision of the Plan to Holders who are officers or directors
subject to Section 16 of the Exchange Act without so restricting, limiting or
conditioning the Plan with respect to other Holders.  Additionally, in
interpreting and applying the provisions of the Plan, any Option granted as an
Incentive Stock Option pursuant to the Plan shall, to the extent permitted by
law, be construed as an "incentive stock option" within the meaning of Section
422 of the Code.

17.6 NO TRUST OR FUND

     The Plan is intended to constitute an "unfunded" plan.  Nothing contained
herein shall require the Company to segregate any monies or other property, or
shares of Common Stock, or to create any trusts, or to make any special deposits
for any immediate or deferred amounts 

                                      -16-
<PAGE>
 
payable to any Holder, and no Holder shall have any rights that are greater than
those of a general unsecured creditor of the Company.

17.7 SEVERABILITY

     If any provision of the Plan or any Award is determined to be invalid,
illegal or unenforceable in any jurisdiction, or as to any person, or would
disqualify the Plan or any Award under any law deemed applicable by the Plan
Administrator, such provision shall be construed or deemed amended to conform to
applicable laws, or, if it cannot be so construed or deemed amended without, in
the Plan Administrator's determination, materially altering the intent of the
Plan or the Award, such provision shall be stricken as to such jurisdiction,
person or Award, and the remainder of the Plan and any such Award shall remain
in full force and effect.

                          SECTION 18.  EFFECTIVE DATE

     The Plan's Effective Date is the date on which it is adopted by the Board,
so long as it is approved by the Company's shareholders at any time within 12
months of such adoption.

     Adopted by the Board on October 23, 1998 and approved by the Company's
shareholders on November 24, 1998.

     (a) Except as otherwise set forth below, the Plan shall be implemented by a
series of Offerings (each, an "Offering").  Offerings shall commence on January
1 and July 1 of each year and end on the next June 30 and December 31,
respectively, occurring thereafter (each, an "Offering Period"); provided,
however, that the first Offering Period shall begin on the day (the "IPO Date")
on which shares of the Company's Stock are first offered to the public in an
underwritten initial public offering of such Stock pursuant to a registration
statement filed with and declared 

                                      -4-

effective by the Securities and Exchange Commission (such day being the first
trading day for the Stock on the Nasdaq National Market, the New York Stock
Exchange or other applicable trading market), and shall end on June 30, 1999.

     (b) Notwithstanding the foregoing, the Board may establish (i) a different
term for one or more Offerings and (ii) different commencing and ending dates
for such Offerings; provided, however, that an Offering Period may not exceed
five years; and provided, further, that if the Purchase Price may be less than
85% of the fair market value of the Stock on the Purchase Date, the Offering
Period may not exceed 27 months.

     (c) In the event the first or the last day of an Offering Period is not a
regular business day, then the first day of the Offering Period shall be deemed
to be the next regular business day and the last day of the Offering Period
shall be deemed to be the last preceding regular business day.  An employee who
becomes eligible to participate in the Plan after an Offering Period has
commenced shall not be eligible to participate in such Offering but may
participate in any subsequent Offering, provided that such employee is still an
Eligible Employee as of the commencement of any such subsequent Offering.
Eligible Employees may not participate in more than one Offering at a time.

5.2  PURCHASE PERIODS

     Each Offering Period shall consist of one or more consecutive purchase
periods (each, a "Purchase Period").  The last day of each Purchase Period shall

below, each Purchase Period shall commence on January 1 and July 1 of each year
and end on the next June 30 and December 31, respectively, occurring thereafter;
provided, however, that the Purchase Period for the first Offering shall
commence on the IPO Date and end on June 30, 1999.  Notwithstanding the
foregoing, the Board may establish (a) a different term for one or more Purchase
Periods and (b) different commencing and ending dates for any such Purchase
Period.  In the event the first or last day of a Purchase Period is not a
regular business day, then the first day of the Purchase Period shall be deemed

     The purchase price (the "Purchase Price") at which Stock may be acquired in
an Offering pursuant to the exercise of all or any portion of an Option granted
under the Plan (the "Offering Exercise Price") shall be 85% of the lesser of (a)
the fair market value of the Stock on the Offering Date of such Offering and (b)
the fair market value of the Stock on the Purchase Date; provided, however, that
the Purchase Price for the first Offering Period that begins on the IPO Date
shall be the lesser of (a) 100% of the initial public offering price per share
of Stock, before underwriters' discounts or concessions, set forth in that
certain Underwriting Agreement between the Company and the representatives of
the underwriters when executed in connection with the Company's initial public
offering of the Stock and (b) 85% of the fair market value of the Stock on the
Purchase Date.  The fair market value of the Stock on the Offering Date or on
the Purchase Date shall be the closing price for the Stock as reported for such
day by the Nasdaq National Market, the New York Stock Exchange or other trading
market on which the Company's Stock may then be traded (the "Exchange").  If no
sales of the Stock were made on the Exchange on such day, fair market value
shall mean the closing price for the Stock as reported for the next preceding
day on which sales of the Stock were made on the Exchange.  If the Stock is not
listed on an Exchange, the Board shall designate an alternative method of
determining the fair market value of the Stock.

                     SECTION 7.  PARTICIPATION IN THE PLAN

7.1  INITIAL PARTICIPATION

     An Eligible Employee shall become a Participant on the first Offering Date
after satisfying the eligibility requirements and delivering to the Plan
Administrator during the enrollment period established by the Plan Administrator
(the "Enrollment Period") a subscription (the "Subscription"):

     (a) indicating the Eligible Employee's election to participate in the Plan;

     (b) authorizing payroll deductions and stating the amount to be deducted
regularly from the Participant's pay; and

     (c) authorizing the purchase of Stock for the Participant in each Purchase
Period.

     An Eligible Employee who does not deliver a Subscription as provided above
during the Enrollment Period shall not participate in the Plan for that Offering
Period or for any subsequent Offering Period unless such Eligible Employee
subsequently 

                                      -6-
<PAGE>
 
enrolls in the Plan by filing a Subscription with the Company during the
Enrollment Period for such subsequent Offering Period. The Company may, from
time to time, change the Enrollment Period for any future Offering as deemed
advisable by the Plan Administrator, in its sole discretion, for the proper
administration of the Plan.

7.2  CONTINUED PARTICIPATION

     A Participant shall automatically participate in the next Offering Period
until such time as such Participant withdraws from the Plan pursuant to Section
11.1 or 11.2 or terminates employment as provided in Section 12.

              SECTION 8.  LIMITATIONS ON RIGHT TO PURCHASE SHARES

8.1  NUMBER OF SHARES PURCHASED

     The maximum number of shares of Stock that may be offered to a Participant
on any Offering Date shall be equal to $25,000 divided by the fair market value
of one share of Stock on the applicable Offering Date.  Further, no Participant
shall be entitled to purchase Stock under the Plan (or any other employee stock
purchase plan that is intended to meet the requirements of Code Section 423
sponsored by the Company, a Parent Corporation or a Subsidiary Corporation) with
a fair market value exceeding $25,000, determined as of the Offering Date for
each Offering Period (or such other limit as may be imposed by the Code), in any
calendar year in which a Participant participates in the Plan (or other employee
stock purchase plan described in this Section 8.1).

8.2  PRO RATA ALLOCATION

     In the event the number of shares of Stock that might be purchased by all
Participants in the Plan exceeds the number of shares of Stock available in the
Plan, the Plan Administrator shall make a pro rata allocation of the remaining
shares of Stock in as uniform a manner as shall be practicable and as the Plan
Administrator shall determine to be equitable.  Fractional shares may not be
issued under the Plan unless the Plan Administrator determines otherwise for
future Offering Periods.

                     SECTION 9.  PAYMENT OF PURCHASE PRICE

9.1  GENERAL RULES

     Subject to Section 9.12, Stock that is acquired pursuant to the exercise of
all or any portion of an Option may be paid for only by means of payroll
deductions from the Participant's Eligible Compensation.  Except as set forth in
this Section 9, the 

                                      -7-
<PAGE>
 
amount of compensation to be withheld from a Participant's Eligible Compensation
during each pay period shall be determined by the Participant's Subscription.

9.2  CHANGE NOTICES

     During an Offering Period, a Participant may elect to decrease, but not
increase, the amount withheld from his or her Eligible Compensation by filing an
amended Subscription with the Company on or before the change notice date.  The
change notice date shall initially be the seventh day prior to the end of the
first pay period for which such election is to be effective; provided, however,
that the Plan Administrator may change such change notice date from time to
time.  Unless otherwise determined by the Plan Administrator for a future
Offering, a Participant may elect to increase or decrease the amount to be
withheld from his or her Eligible Compensation for future Offerings; provided,
however, that notice of such election must be delivered to the Plan
Administrator in such form and in accordance with such terms as the Plan
Administrator may establish for an Offering.

9.3  PERCENT WITHHELD

     The amount of payroll withholding for each Participant for purchases
pursuant to the Plan during any pay period shall be at least 1% but shall not
exceed 10% of the Participant's Eligible Compensation for such pay period.
Amounts shall be withheld in whole percentages only.

9.4  PAYROLL DEDUCTIONS

     Payroll deductions shall commence on the first payday following the
Offering Date and shall continue through the last payday of the Offering Period
unless sooner altered or terminated as provided in the Plan.

9.5  MEMORANDUM ACCOUNTS

     Individual accounts shall be maintained for each Participant for memorandum
purposes only.  All payroll deductions from a Participant's Eligible
Compensation shall be credited to such account but shall be deposited with the
general funds of the Company.  All payroll deductions received or held by the
Company may be used by the Company for any corporate purpose.

9.6  NO INTEREST

     No interest shall be paid on payroll deductions received or held by the
Company.

                                      -8-
<PAGE>
 
9.7  ACQUISITION OF STOCK

     On each Purchase Date of an Offering Period, each Participant shall
automatically acquire, pursuant to the exercise of the Participant's Option, the
number of shares of Stock arrived at by dividing the total amount of the
Participant's accumulated payroll deductions for the Purchase Period by the
Purchase Price; provided, however, that the number of shares of Stock purchased
by the Participant shall not exceed the number of whole shares of Stock so
determined, unless the Plan Administrator has determined for any future Offering
that fractional shares may be issued under the Plan; and provided, further, that
the number of shares of Stock purchased by the Participant shall not exceed the
number of shares for which Options have been granted to the Participant pursuant
to Section 8.1.

9.8  REFUND OF EXCESS AMOUNTS

     Any cash balance remaining in the Participant's account at the termination
of each Purchase Period shall be refunded to the Participant as soon as
practical after the Purchase Date without the payment of any interest; provided,
however, that if the Participant participates in the next Purchase Period, any
cash balance remaining in the Participant's account shall be applied to the
purchase of Stock in the new Purchase Period, provided such purchase complies
with Section 8.1.

9.9  WITHHOLDING OBLIGATIONS

     At the time the Option is exercised, in whole or in part, or at the time
some or all of the Stock is disposed of, the Participant shall make adequate
provision for federal and state withholding obligations of the Company, if any,
that arise upon exercise of the Option or upon disposition of the Stock.  The
Company may withhold from the Participant's compensation the amount necessary to
meet such withholding obligations.

9.10  TERMINATION OF PARTICIPATION

     No Stock shall be purchased on behalf of a Participant on a Purchase Date
if his or her participation in the Offering or the Plan has terminated on or
before such Purchase Date.

9.11  PROCEDURAL MATTERS

     The Company may, from time to time, establish (a) limitations on the
frequency and/or the number of any permitted changes in the amount withheld
during an Offering, as set forth in Section 9.2, (b) an exchange ratio
applicable to amounts 

                                      -9-
<PAGE>
 
withheld in a currency other than U.S. dollars, (c) payroll withholding in
excess of the amount designated by a Participant in order to adjust for delays
or mistakes in the Company's processing of properly completed withholding
elections and (d) such other limitations or procedures as deemed advisable by
the Company in its sole discretion that are consistent with the Plan and in
accordance with the requirements of Code Section 423.

9.12  LEAVES OF ABSENCE

     During leaves of absence approved by the Company and meeting the
requirements of the applicable Treasury Regulations promulgated under the Code,
a Participant may elect to continue participation in the Plan by delivering cash
payments to the Plan Administrator on the Participant's normal paydays equal to
the amount of his or her payroll deduction under the Plan had the Participant
not taken a leave of absence.  Currently, the Treasury Regulations provide that
a Participant may continue participation in the Plan only during the first 90
days of a leave of absence unless the Participant's reemployment rights are
guaranteed by statute or contract.

                  SECTION 10.  STOCK PURCHASED UNDER THE PLAN

10.1  ESPP BROKER

     If the Plan Administrator designates or approves a stock brokerage or other
financial services firm (the "ESPP Broker") to hold shares purchased under the
Plan for the accounts of Participants, the following procedures shall apply.
Promptly following each Purchase Date, the number of shares of Stock purchased
by each Participant shall be deposited into an account established in the
Participant's name with the ESPP Broker.  A Participant shall be free to
undertake a disposition of the shares of Stock in his or her account at any time
but, in the absence of such a disposition, the shares of Stock must remain in
the Participant's account at the ESPP Broker until the holding period set forth
in Code Section 423 has been satisfied.  With respect to shares of Stock for
which the holding periods set forth above have been satisfied, the Participant
may move those shares of Stock to another brokerage account of the Participant's
choosing or request that a stock certificate be issued and delivered to him or
her.  Any dividends paid in the form of shares of Stock with respect to Stock in
a Participant's account shall be credited to such account.  A Participant who is
not subject to payment of U.S. income taxes may move his or her shares of Stock
to another brokerage account of his or her choosing or request that a stock
certificate be delivered to him or her at any time, without regard to the Code
Section 423 holding period.

                                      -10-
<PAGE>
 
10.2  NOTICE OF DISPOSITION

     By entering the Plan, each Participant agrees to promptly give the Company
notice of any Stock disposed of within the later of one year from the Purchase
Date and two years from the Offering Date for such Stock, showing the number of
such shares disposed of and the Purchase Date and Offering Date for such Stock.
This notice shall not be required if and so long as the Company has a designated
ESPP Broker.

                       SECTION 11.  VOLUNTARY WITHDRAWAL

11.1  WITHDRAWAL FROM AN OFFERING

     A Participant may withdraw from an Offering by signing and delivering to
the Company's Plan Administrator a written notice of withdrawal on a form
provided by the Company for such purpose.  Such withdrawal must be elected at
least ten days prior to the end of the Purchase Period for which such withdrawal
is to be effective or by any other date specified by the Plan Administrator for
any future Offering.  If a Participant withdraws after the Purchase Date for a
Purchase Period of an Offering, the withdrawal shall not affect Stock acquired
by the Participant in any earlier Purchase Periods.  Unless otherwise indicated,
withdrawal from an Offering shall not result in a withdrawal from the Plan or
any succeeding Offering therein.  A Participant is prohibited from again
participating in the same Offering at any time upon withdrawal from such
Offering.  The Company may, from time to time, impose a requirement that the
notice of withdrawal be on file with the Plan Administrator for a reasonable
period prior to the effectiveness of the Participant's withdrawal.

11.2  WITHDRAWAL FROM THE PLAN

     A Participant may withdraw from the Plan by signing a written notice of
withdrawal on a form provided by the Company for such purpose and delivering
such notice to the Plan Administrator.  Such notice must be delivered at least
ten days prior to the end of the Purchase Period for which such withdrawal is to
be effective or by any other date specified by the Plan Administrator for any
future Offering.  In the event a Participant voluntarily elects to withdraw from
the Plan, the Participant may not resume participation in the Plan during the
same Offering Period, but may participate in any subsequent Offering under the
Plan by again satisfying the definition of Eligible Employee.  The Company may
impose, from time to time, a requirement that the notice of withdrawal be on
file with the Plan Administrator for a reasonable period prior to the
effectiveness of the Participant's withdrawal.

11.3  RETURN OF PAYROLL DEDUCTIONS

     Upon withdrawal from an Offering pursuant to Section 11.1 or from the Plan
pursuant to Section 11.2, the withdrawing Participant's accumulated payroll
deductions that have not been applied to the purchase of Stock shall be returned
as soon as practical after the withdrawal, without the payment of any interest,
to the Participant and the Participant's interest in the Offering shall
terminate.  Such accumulated payroll deductions may not be applied to any other
Offering under the Plan.

                     SECTION 12.  TERMINATION OF EMPLOYMENT

     Termination of a Participant's employment with the Company for any reason,
including retirement, death or the failure of a Participant to remain an
Eligible Employee, shall immediately terminate the Participant's participation
in the Plan.  The payroll deductions credited to the Participant's account since
the last Purchase Date shall, as soon as practical, be returned to the
Participant or, in the case of a Participant's death, to the Participant's legal
representative or designated beneficiary as provided in Section 13.2, and all of
the Participant's rights under the Plan shall terminate.  Interest shall not be
paid on sums returned to a Participant pursuant to this Section 12.

                    SECTION 13.  RESTRICTIONS ON ASSIGNMENT

13.1  TRANSFERABILITY

     An Option granted under the Plan shall not be transferable and such Option
shall be exercisable during the Participant's lifetime only by the Participant.
The Company will not recognize, and shall be under no duty to recognize, any
assignment or purported assignment by a Participant of the Participant's
interest in the Plan, of his or her Option or of any rights under his or her
Option.

13.2  BENEFICIARY DESIGNATION

     The Plan Administrator may permit a Participant to designate a beneficiary
who is to receive any shares and cash, if any, from the Participant's account
under the Plan in the event the Participant dies after the Purchase Date for an
Offering but prior to delivery to such Participant of such shares and cash.  In
addition, the Plan Administrator may permit a Participant to designate a
beneficiary who is to receive any cash from the Participant's account under the
Plan in the event that the Participant dies before the Purchase Date for an
Offering.  Such designation may be changed by the Participant at any time by
written notice to the Plan Administrator.

<PAGE>
 
           SECTION 14.  NO RIGHTS AS SHAREHOLDER UNTIL SHARES ISSUED

     With respect to shares of Stock subject to an Option, a Participant shall
not be deemed to be a shareholder of the Company, and he or she shall not have
any rights or privileges of a shareholder.  A Participant shall have the rights
and privileges of a shareholder of the Company when, but not until, a
certificate or its equivalent has been issued to the Participant for the shares
of Stock following exercise of the Participant's Option.

       SECTION 15.  LIMITATIONS ON SALE OF STOCK PURCHASED UNDER THE PLAN

     The Plan is intended to provide Stock for investment and not for resale.
The Company does not, however, intend to restrict or influence any Participant
in the conduct of his or her own affairs.  A Participant, therefore, may sell
Stock purchased under the Plan at any time he or she chooses, subject to
compliance with any applicable federal and state securities laws.  A Participant
assumes the risk of any market fluctuations in the price of the Stock.

                       SECTION 16.  AMENDMENT OF THE PLAN

     The Board may amend the Plan in such respects as it shall deem advisable;
provided, however, that, to the extent required for compliance with Code Section
423 or any applicable law or regulation, shareholder approval will be required
for any amendment that will (a) increase the total number of shares as to which
Options may be granted under the Plan, (b) modify the class of employees
eligible to receive Options, or (c) otherwise require shareholder approval under
any applicable law or regulation.

                      SECTION 17.  TERMINATION OF THE PLAN

     The Plan shall continue in effect for ten years after the date of its
adoption by the Board.  Notwithstanding the foregoing, the Board may suspend or
terminate the Plan at any time.  During any period of suspension or upon
termination of the Plan, no Options shall be granted; provided, however, that
suspension or termination of the Plan shall have no effect on Options granted
prior thereto.

                     SECTION 18.  NO RIGHTS AS AN EMPLOYEE

     Nothing in the Plan shall be construed to give any person (including any
Eligible Employee or Participant) the right to remain in the employ of the
Company or a Parent or Subsidiary Corporation or to affect the right of the
Company or a Parent or 

                                      -13-
<PAGE>
 
Subsidiary Corporation to terminate the employment of any person (including any
Eligible Employee or Participant) at any time with or without cause.

                      SECTION 19.  EFFECT UPON OTHER PLANS

     The adoption of the Plan shall not affect any other compensation or
incentive plans in effect for the Company or any Parent or Subsidiary
Corporation.  Nothing in the Plan shall be construed to limit the right of the
Company, any Parent Corporation or Subsidiary Corporation to (a) establish any
other forms of incentives or compensation for employees of the Company, a Parent
Corporation or Subsidiary Corporation or (b) grant or assume options otherwise
than under the Plan in connection with any proper corporate purpose, including,
but not by way of limitation, the grant or assumption of options in connection
with the acquisition, by purchase, lease, merger, consolidation or otherwise, of
the business, stock or assets of any corporation, firm or association.

                            SECTION 20.  ADJUSTMENTS

20.1  ADJUSTMENT OF SHARES

     In the event that, at any time or from time to time, a stock dividend,
stock split, spin-off, combination or exchange of shares, recapitalization,
merger, consolidation, distribution to shareholders other than a normal cash
dividend, or other change in the Company's corporate or capital structure
results in (a) the outstanding shares, or any securities exchanged therefor or
received in their place, being exchanged for a different number or kind of
securities of the Company or of any other corporation or (b) new, different or
additional securities of the Company or of any other corporation being received
by the holders of shares of Stock, then (subject to any required action by the
Company's shareholders), the Board or the Committee, in its sole discretion,
shall make such equitable adjustments as it shall deem appropriate in the
circumstances in (i) the maximum number and kind of shares of Stock subject to
the Plan as set forth in Section 4 and (ii) the number and kind of securities
that are subject to any outstanding Option and the per share price of such
securities.  The determination by the Board or the Committee as to the terms of
any of the foregoing adjustments shall be conclusive and binding.
Notwithstanding the foregoing, a dissolution or liquidation of the Company or a
Corporate Transaction shall not be governed by this Section 20.1 but shall be
governed by Sections 20.2 and 20.3, respectively.

                                      -14-
<PAGE>
 
20.2  DISSOLUTION OR LIQUIDATION OF THE COMPANY

     In the event of the proposed dissolution or liquidation of the Company, the
Offering Period then in progress shall be shortened by setting a new Purchase
Date (the "New Purchase Date"), and shall terminate immediately prior to the
consummation of such proposed dissolution or liquidation, unless provided
otherwise by the Board.  The New Purchase Date shall be a specified date before
the date of the Company's proposed dissolution or liquidation.  The Board shall
notify each Participant in writing, at least ten business days prior to the New
Purchase Date, that the Purchase Date for the Participant's Option has been
changed to the New Purchase Date and that the Participant's Option shall be
exercised automatically on the New Purchase Date, unless prior to such date the
Participant has withdrawn from the Offering Period or the Plan as provided in
Section 11 hereof.

20.3  CORPORATE TRANSACTIONS

     In the event of a Corporate Transaction, each outstanding Option shall be
assumed or an equivalent option substituted by the successor corporation or a
parent or subsidiary corporation of the successor corporation.  In the event
that the successor corporation refuses to assume or substitute for the Option,
the Offering Period then in progress shall be shortened by setting a new
Purchase Date (the "New Purchase Date").  The New Purchase Date shall be a
specified date before the date of the Corporate Transaction.  The Board shall
notify each Participant in writing, at least ten business days prior to the New
Purchase Date, that the Purchase Date for the Participant's Option has been
changed to the New Purchase Date and that the Participant's Option shall be
exercised automatically on the New Purchase Date, unless prior to such date the
Participant has withdrawn from the Offering Period or the Plan as provided in
Section 11 hereof.

20.4  LIMITATIONS

     The grant of Options shall in no way affect the Company's right to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

               SECTION 21.  REGISTRATION; CERTIFICATES FOR SHARES

     The Company shall be under no obligation to any Participant to register for
offering or resale under the Securities Act of 1933, as amended, or register or
qualify under state securities laws, any shares of Stock.  The Company may issue
certificates for shares with such legends and subject to such restrictions on
transfer and 

                                      -15-
<PAGE>
 
stop-transfer instructions as counsel for the Company deems necessary or
desirable for compliance by the Company with federal and state securities laws.

                          SECTION 22.  EFFECTIVE DATE

     The Plan's effective date is the date on which it is approved by the
Company's shareholders.

                           ONYX SOFTWARE CORPORATION

                           INDEMNIFICATION AGREEMENT

     This Indemnification Agreement (this "Agreement") dated as of _______ __,
1998 is made between ONYX Software Corporation, a Washington corporation (the
"Company"), and ________________ ("Indemnitee").

                                    RECITALS

     A.  Indemnitee is a director or officer of the Company and in such capacity
is performing valuable services for the Company.

     B.  The Company and Indemnitee recognize the difficulty in obtaining
directors' and officers' liability insurance and the significant cost of such
insurance.

     C.  The Company and Indemnitee further recognize the substantial increase
in litigation subjecting directors and officers to expensive litigation risks at
the same time that such liability insurance has been severely limited.

     D.  The Company has adopted bylaws (the "Bylaws") providing for
indemnification of the officers, directors, agents and employees of the Company
to the full extent permitted by the Business Corporation Act of Washington (the
"Statute").

     E.  The Bylaws and the Statute specifically provide that they are not
exclusive, and thereby contemplate that contracts may be entered into between
the Company and its directors and officers with respect to indemnification of
such directors and officers.

     F.  To induce Indemnitee to serve or continue to serve as a director or
officer of the Company, the Company desires to confirm the contract
indemnification rights provided in the Bylaws and agrees to provide the
Indemnitee with the benefits contemplated by this Agreement.

                                   AGREEMENT

     In consideration of the recitals above, the mutual covenants and agreements
herein contained, and Indemnitee's continued service as a director or officer,
as the case may be, of the Company after the date hereof, the parties to this
Agreement agree as follows:

1.   INDEMNIFICATION OF INDEMNITEE

     1.1.   SCOPE

     The Company agrees to hold harmless and indemnify Indemnitee to the full
extent provided under the provisions of the Company's Fourth Restated Articles
of Incorporation and 

                                     Page 1
<PAGE>
 
the Bylaws, and to the full extent permitted by law, notwithstanding that the
basis for such indemnification is not specifically enumerated in this Agreement,
the Company's Fourth Restated Articles of Incorporation, the Bylaws, any statute
or otherwise. In the event of any change, after the date of this Agreement, in
any applicable law, statute or rule regarding the right of a Washington
corporation to indemnify a member of its board of directors or an officer, such
change, to the extent that it would expand Indemnitee's rights hereunder, shall
be included within Indemnitee's rights and the Company's obligations hereunder,
and, to the extent that it would narrow Indemnitee's rights or the Company's
obligations hereunder, shall not affect or limit the scope of this Agreement;
provided, however, that in no event shall any part of this Agreement be
construed so as to require indemnification when such indemnification is not
permitted by then applicable law.

     1.2.   NONEXCLUSIVITY

     The indemnification provided by this Agreement shall not be deemed
exclusive of any rights to which Indemnitee may be entitled under the Company's
Fourth Restated Articles of Incorporation, the Bylaws, any agreement, any vote
of shareholders or disinterested directors, the Statute, or otherwise, whether
as to action in Indemnitee's official capacity or otherwise.

     1.3.  INCLUDED COVERAGE

     If Indemnitee was or is made a party, or is threatened to be made a party,
to or is otherwise involved (including, without limitation, as a witness) in any
Proceeding (as defined below), the Company shall hold harmless and indemnify
Indemnitee from and against any and all losses, claims, damages (compensatory,
exemplary, punitive or otherwise), liabilities or expenses, including, without
limitation, attorneys' fees, costs, judgments, fines, ERISA excise taxes or
penalties, witness fees, amounts paid in settlement and other expenses incurred
in connection with the investigation, defense, settlement or approval of such
Proceeding (collectively, "Damages").

     1.4.  DEFINITION OF PROCEEDING

     For purposes of this Agreement, "Proceeding" shall mean any completed,
actual, pending or threatened action, suit, claim, hearing or proceeding,
whether civil, criminal, arbitrative, administrative, investigative or pursuant
to any alternative dispute resolution mechanism (including an action by or in
the right of the Company) and whether formal or informal, in which Indemnitee
is, was or becomes involved by reason of the fact that Indemnitee is or was a
director, officer, employee or agent of the Company or that, being or having
been such a director, officer, employee or agent, Indemnitee is or was serving
at the request of the Company as a director, officer, employee, trustee or agent
of another corporation or of a partnership, joint venture, trust or other
enterprise (collectively, a "Related Company"), including service with respect
to an employee benefit plan, whether the basis of such proceeding is alleged
action (or inaction) by Indemnitee in an official capacity as a director,
officer, employee, trustee or agent or in any other capacity while serving as a
director, officer, employee, trustee or agent; provided, however, that, except
with respect to 

                                     Page 2
<PAGE>
 
an Enforcement Action (defined in Section 3.1 below, an action challenging the
Company's determination that Indemnitee is not entitled to indemnification
pursuant to Section 1.5, and any other action to enforce the provisions of this
Agreement, "Proceeding" shall not include any action, suit, claim or proceeding
instituted by or at the direction of Indemnitee unless such action, suit, claim
or proceeding is or was authorized by the Company's Board of Directors.

     1.5.  DETERMINATION OF ENTITLEMENT

     In the event that a determination of Indemnitee's entitlement to
indemnification is required pursuant to Section 23B.08.550 of the Statute or a
successor statute or pursuant to other applicable law, the appropriate decision-
maker shall make such determination; provided, however, that Indemnitee shall
initially be presumed in all cases to be entitled to indemnification, that
Indemnitee may establish a conclusive presumption of any fact necessary to such
a determination by delivering to the Company a declaration made under penalty of
perjury that such fact is true and that, unless the Company shall deliver to
Indemnitee written notice of a determination that Indemnitee is not entitled to
indemnification within twenty (20) calendar days after the Company's receipt of
Indemnitee's initial written request for indemnification, such determination
shall conclusively be deemed to have been made in favor of the Company's
provision of indemnification, and that the Company hereby agrees not to assert
otherwise.

     1.6.  CONTRIBUTION

     If the indemnification provided under Section 1.1 is unavailable by reason
of a court decision, based on grounds other than any of those set forth in
paragraphs (b) through (d) of Section 4.1, then, in respect of any Proceeding in
which the Company is jointly liable with Indemnitee (or would be if joined in
such Proceeding), the Company shall contribute to the amount of Damages
(including attorneys' fees) actually and reasonably incurred and paid or payable
by Indemnitee in such proportion as is appropriate to reflect (i) the relative
benefits received by the Company on the one hand and Indemnitee on the other
from the transaction from which such Proceeding arose and (ii) the relative
fault of the Company on the one hand and of Indemnitee on the other in
connection with the events that resulted in such Damages as well as any other
relevant equitable considerations.  The relative fault of the Company on the one
hand and of Indemnitee on the other shall be determined by reference to, among
other things, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent the circumstances resulting in such Damages.
The Company agrees that it would not be just and equitable if contribution
pursuant to this Section 1.6 were determined by pro rata allocation or any other
method of allocation that does not take account of the foregoing equitable
considerations.

     1.7.  SURVIVAL

     The indemnification and contribution provided under this Agreement shall
apply to any and all Proceedings, notwithstanding that Indemnitee has ceased to
serve the Company or a Related Company and shall continue so long as Indemnitee
shall be subject to any possible 

                                     Page 3
<PAGE>
 
Proceeding, whether civil, criminal or investigative, by reason of the fact that
Indemnitee was a director or officer of the Company or serving in any other
capacity referred to in Section 1.4 of this Agreement.

2.   EXPENSE ADVANCES

     2.1.  GENERALLY

     The right to indemnification of Damages conferred by Section 1 shall
include the right to have the Company pay Indemnitee's expenses in any
Proceeding as such expenses are incurred and in advance of such Proceeding's
final disposition (such right, an "Expense Advance").

     2.2.  CONDITIONS TO EXPENSE ADVANCE

     The Company's obligation to provide an Expense Advance is subject to the
following conditions:

          2.2.1.  UNDERTAKING

          If the Proceeding arose in connection with Indemnitee's service as a
director or an officer of the Company (and not in any other capacity in which
Indemnitee rendered service, including service to any Related Company), then
Indemnitee or Indemnitee's representative shall have executed and delivered to
the Company an undertaking, which need not be secured and shall be accepted
without reference to Indemnitee's financial ability to make repayment, by or on
behalf of Indemnitee to repay all Expense Advances if it shall ultimately be
determined by a final, unappealable decision rendered by a court having
jurisdiction over the parties that Indemnitee is not entitled to be indemnified
under this Agreement or otherwise.

          2.2.2.  COOPERATION

          Indemnitee shall give the Company such information and cooperation as
it may reasonably request and as shall be within Indemnitee's legal power to so
provide.

          2.2.3.  AFFIRMATION

          Indemnitee shall furnish, upon request by the Company and if required
under applicable law, a written affirmation of Indemnitee's good faith belief
that any applicable standards of conduct have been met by Indemnitee.

                                     Page 4
<PAGE>
 
3.   PROCEDURES FOR ENFORCEMENT

     3.1.  ENFORCEMENT

     In the event that any claim for indemnification, whether an Expense Advance
or otherwise, is made hereunder and is not paid in full within thirty (30)
calendar days after written notice of such claim is delivered to the Company,
Indemnitee may, but need not, at any time thereafter bring suit against the
Company to recover the unpaid amount of the claim (an "Enforcement Action").

     3.2.  PRESUMPTIONS IN ENFORCEMENT ACTION

     In any Enforcement Action, the following presumptions (and limitation on
presumptions) shall apply:

     (a) The Company expressly affirms and agrees that it has entered into this
Agreement and assumed the obligations imposed on it hereunder to induce
Indemnitee to continue as a director or officer, as the case may be, of the
Company;

     (b) Neither (i) the failure of the Company (including the Company's Board
of Directors, independent or special legal counsel or the Company's
shareholders) to have made a determination prior to the commencement of the
Enforcement Action that indemnification of Indemnitee is proper in the
circumstances nor (ii) an actual determination by the Company, its Board of
Directors, independent or special legal counsel or shareholders that Indemnitee
is not entitled to indemnification shall be a defense to the Enforcement Action
or create a presumption that Indemnitee is not entitled to indemnification
hereunder; and

     (c) If Indemnitee is or was serving as a director or officer of a
corporation of which a majority of the shares entitled to vote in the election
of its directors is held by the Company or as a partner, trustee or otherwise in
an executive or management capacity in a partnership, joint venture, trust or
other enterprise of which the Company or a wholly owned subsidiary of the
Company is a general partner or has a majority ownership, then such corporation,
partnership, joint venture, trust or other enterprise shall conclusively be
deemed a Related Company and Indemnitee shall conclusively be deemed to be
serving such Related Company at the Company's request.

     3.3.  ATTORNEYS' FEES AND EXPENSES FOR ENFORCEMENT ACTION

     In the event Indemnitee is required to bring an Enforcement Action, the
Company shall pay all of Indemnitee's fees and expenses in bringing and pursuing
the Enforcement Action (including attorneys' fees at any stage, including on
appeal); provided, however, that the Company shall not be required to provide
such payment for such attorneys' fees or expenses if a court of competent
jurisdiction determines that each of the material assertions made by Indemnitee
in such Enforcement Action was not made in good faith.

4.   LIMITATIONS ON INDEMNITY; MUTUAL ACKNOWLEDGMENT

     4.1.  LIMITATION ON INDEMNITY

     No indemnity pursuant to this Agreement shall be provided by the Company:

     (a) On account of any suit in which a final, unappealable judgment is
rendered against Indemnitee for an accounting of profits made from the purchase
or sale by Indemnitee of securities of the Company in violation of the
provisions of Section 16(b) of the Securities Exchange Act of 1934, as amended;

     (b) For Damages that have been paid directly to Indemnitee by an insurance
carrier under a policy of insurance maintained by the Company;

     (c) With respect to remuneration paid to Indemnitee if it shall be
determined by a final judgment or other final adjudication that such
remuneration was in violation of law;

     (d) On account of Indemnitee's conduct which is finally adjudged by a court
having jurisdiction in the matter to have been intentional misconduct, a knowing
violation of law or the RCW 23B.08.310 or any successor provision of the
Statute, or a transaction from which Indemnitee derived an improper personal
benefit; or

     (e) If a final decision by a court having jurisdiction in the matter with
no further right of appeal shall determine that such indemnification is not
lawful.

     4.2.  PARTIAL INDEMNIFICATION

     If Indemnitee is entitled under any provision of this Agreement to
indemnification by the Company for some or a portion of any Damages in
connection with a Proceeding, but not, however, for the total amount thereof,
the Company shall nevertheless indemnify Indemnitee for the portion of such
Damages to which Indemnitee is entitled.

     4.3.  MUTUAL ACKNOWLEDGMENT

     The Company and Indemnitee acknowledge that, in certain instances, federal
law or public policy may override applicable state law and prohibit the Company
from indemnifying Indemnitee under this Agreement or otherwise.  For example,
the Company and Indemnitee acknowledge that the Securities and Exchange
Commission (the "SEC") has taken the position that indemnification is not
permissible for liabilities arising under certain federal securities laws, and
federal legislation prohibits indemnification for certain ERISA violations.
Furthermore, Indemnitee understands and acknowledges that the Company has
undertaken or may be required in the future to undertake with the SEC to submit
the question of indemnification to a court in certain circumstances for a
determination of the Company's right under public policy to indemnify
Indemnitee.

<PAGE>
 
5.   NOTIFICATION AND DEFENSE OF CLAIM

     5.1.  NOTIFICATION

     Promptly after receipt by Indemnitee of notice of the commencement of any
Proceeding, Indemnitee shall, if a claim in respect thereof is to be made
against the Company under this Agreement, notify the Company of the commencement
thereof; but the omission so to notify the Company will not, however, relieve
the Company from any liability which it may have to Indemnitee under this
Agreement unless and only to the extent that such omission can be shown to have
prejudiced the Company's ability to defend the Proceeding.

     If, at the time of the receipt of a notice of a claim pursuant to Section
5.1, the Company has director and officer liability insurance in effect, the
Company shall give prompt notice of the commencement of such proceeding to the
insurers in accordance with the procedures set forth in the respective policies.
The Company shall take all necessary or desirable action to cause such insurers
to pay, on behalf of the Indemnitee, all amounts payable as a result of such
Proceeding in accordance with the terms of such policies.

     5.2.  DEFENSE OF CLAIM

     With respect to any such Proceeding as to which Indemnitee notifies the
Company of the commencement thereof:

     (a) The Company may participate therein at its own expense;

     (b) The Company, jointly with any other indemnifying party similarly
notified, may assume the defense thereof, with counsel satisfactory to
Indemnitee.  After notice from the Company to Indemnitee of its election so to
assume the defense thereof, the Company shall not be liable to Indemnitee under
this Agreement for any legal or other expenses (other than reasonable costs of
investigation) subsequently incurred by Indemnitee in connection with the
defense thereof unless (i) the employment of counsel by Indemnitee has been
authorized by the Company, (ii) Indemnitee shall have reasonably concluded that
there may be a conflict of interest between the Company (or any other person or
persons included in the joint defense) and Indemnitee in the conduct of the
defense of such action, (iii) the Company shall not, in fact, have employed
counsel to assume the defense of such action, in each of which cases the fees
and expenses of counsel shall be at the Company's expense, or (iv) the Company
is not financially or legally able to perform its indemnification obligations.
The Company shall not be entitled to assume the defense of any  proceeding
brought by or on behalf of the Company or as to which Indemnitee shall have
reasonably made the conclusion provided for in (ii) or (iv) above;

     (c) The Company shall not be liable to indemnify Indemnitee under this
Agreement for any amounts paid in settlement of any Proceeding effected without
its written consent;

     (d) The Company shall not settle any action or claim in any manner that
would impose any penalty or limitation on Indemnitee without Indemnitee's
written consent; and

                                     Page 7
<PAGE>
 
     (e) Neither the Company nor Indemnitee will unreasonably withhold its, his
or her consent to any proposed settlement.

6.   SEVERABILITY

     Nothing in this Agreement is intended to require or shall be construed as
requiring the Company to do or to fail to do any act in violation of applicable
law.  The Company's inability, pursuant to court order, to perform its
obligations under this Agreement shall not constitute a breach of this
Agreement.  The provisions of this Agreement shall be severable, as provided in
this Section 6.  If this Agreement or any portion hereof shall be invalidated on
any ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify or make contribution to Indemnitee to the full extent
permitted by any applicable portion of this Agreement that shall not have been
invalidated, and the balance of this Agreement not so invalidated shall be
enforceable in accordance with its terms.

7.   GOVERNING LAW; BINDING EFFECT; AMENDMENT AND TERMINATION

     (a) This Agreement shall be interpreted and enforced in accordance with the
laws of the State of Washington.

     (b) This Agreement shall be binding on Indemnitee and on the Company and
its successors and assigns (including any transferee of all or substantially all
its assets and any successor by merger or otherwise by operation of law), and
shall inure to the benefit of Indemnitee and Indemnitee's heirs, personal
representatives and assigns and to the benefit of the Company and its successors
and assigns.  The Company shall not effect any merger, consolidation, sale of
all or substantially all of its assets or other reorganization in which it is
not the surviving entity, unless the surviving entity agrees in writing to
assure all of the Company's obligations under this Agreement.

     (c) No amendment, modification, termination or cancellation of this
Agreement shall be effective unless in writing signed by both parties hereto.

8.   ENTIRE AGREEMENT

     This Agreement is the entire agreement of the parties regarding its subject
matter and supersedes all prior written or oral communications or agreements.

9.   COUNTERPARTS

     This Agreement may be executed in two or more counterparts, each of which
shall be deemed an original, but all of which together shall constitute one
instrument.

10.  AMENDMENTS; WAIVERS

     Neither this Agreement nor any provision may be amended except by written
agreement signed by the parties.  No waiver of any breach or default shall be
considered valid 

                                     Page 8
<PAGE>
 
unless in writing, and no such waiver shall be deemed a waiver of any subsequent
breach or default.

11.   NOTICES

     All notices, claims and other communications hereunder shall be in writing
and made by hand delivery, registered or certified mail (postage prepaid, return
receipt requested), facsimile or overnight air courier guaranteeing next-day
delivery:

      (a)  If to the Company, to:            with a copy to:

      ONYX Software Corporation              Perkins Coie
      310 - 120th Avenue N.E.                1201 Third Avenue, 40th Floor

      Attn: Sarwat Ramadan,                  Attn: Gregory Gorder, Esq
            Chief Financial Officer

     (b) If to Indemnitee, to the address specified on the last page of this
Agreement or to such other address as either party may from time to time furnish
to the other party by a notice given in accordance with the provisions of this
Section 11.  All such notices, claims and communications shall be deemed to have
been duly given if (i) personally delivered, at the time delivered, (ii) mailed,
five days after dispatched, (iii) sent by facsimile transmission, upon
confirmation of receipt, and (iv) sent by any other means, upon receipt.

12.  DIRECTORS' AND OFFICERS' INSURANCE

     (a) The Company hereby covenants and agrees that, subject to the provisions
of Section 12(c) hereof, the Company shall, from a date no later than the
closing date of the Company's first registered public offering of the Company's
Common Stock pursuant to an effective registration statement under the
Securities Act of 1933, as amended, maintain directors' and officers' insurance
in full force and effect so long as Indemnitee continues to serve as a director
or officer of the Company and thereafter so long as Indemnitee shall be subject
to any possible Proceeding.

     (b) In all policies of directors' and officers' insurance, Indemnitee shall
be named as an insured in such a manner as to provide Indemnitee the same rights
and benefits, subject to the same limitations, as are accorded to the Company's
directors or officers most favorably insured by such policy.

     (c) Notwithstanding the foregoing provisions of this Section 12, the
Company shall have no obligation to maintain directors' and officers' insurance
if the Company determines in good faith that such insurance is not reasonably
available, the premium costs for such insurance are disproportionate to the
amount of coverage provided, or the coverage provided by such insurance is
limited by exclusions so as to provide an insufficient benefit.

13.  SPECIFIC PERFORMANCE

     The Company and Indemnitee agree herein that a monetary remedy for breach
of this Agreement, at some later date, will be inadequate, impracticable and
difficult of proof, and further agree that such breach would cause Indemnitee
irreparable harm.  Accordingly, the Company and Indemnitee agree that Indemnitee
shall be entitled to temporary and permanent injunctive relief to enforce this
Agreement without the necessity of proving actual damages or irreparable harm.
The Company and Indemnitee further agree that Indemnitee shall be entitled to
such injunctive relief, including temporary restraining orders, preliminary
injunctions and permanent injunctions, without the necessity of posting bond or
other undertaking in connection therewith.  Any such requirement of bond or
undertaking is hereby waived by the Company, and the Company acknowledges that
in the absence of such a waiver, a bond or undertaking may be required by the
court.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement on and
as of the day and year first above written.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS,
                        ON FINANCIAL STATEMENT SCHEDULE
 
  We have audited the consolidated balance sheets of ONYX Software Corporation
as of December 31, 1996 and 1997 and September 30, 1998, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended December 31, 1997 and the nine
months ended September 30, 1998, and have issued our report thereon dated
November 16, 1998 (except Note 12 as to which the date is      ) (included
elsewhere in this Registration Statement). Our audits also included the
financial statement schedule listed in Item 16(b) of this Registration
Statement. This schedule is the responsibility of the Company's management. Our
responsibility is to express an opinion based on our audits.
 
  In our opinion, the financial statement schedule referred to above, when
considered in relation to the basic financial statements taken as a whole,
presents fairly in all material respects the information set forth therein.
