information you should consider before buying shares in this offering. You
should read the entire prospectus carefully.
 
                        Primus Knowledge Solutions, Inc.
 
  We are a leading provider of Web-based problem-resolution software for
customer support and self-service. Our applications enable businesses to
capture problem-resolution information, solve customer problems, reuse
solutions stored in the knowledge base and share captured knowledge throughout
the extended enterprise. Our SolutionSeries family of software products
enhances an organization's problem-resolution capabilities by using our
associative problem-solving technology and leveraging the Internet to extend
customer support to remote employees, business partners and end-user customers.
 
  We believe our software allows organizations to improve customer satisfaction
levels and decrease support costs by:
 
  . reducing the overall time needed to resolve problems
  . improving first-call resolution rates
  . increasing call deflections to the Web
  . reducing escalation of problems to senior analysts
  . increasing solution reuse
  . reducing training time
 
  We believe that our SolutionSeries products enable our users to realize a
substantial economic return on their investment by:
 
  . Enhancing problem resolution through associative problem-solving
    technology
    We developed our products using associative problem-solving technology,
    rather than alternative methodologies such as enhanced text retrieval,
    decision trees and case-based reasoning, to improve the relevance of
    solutions retrieved, support and enhance diverse problem-solving approaches
    and cost-effectively capture knowledge in the workflow.
  . Leveraging Internet technology to extend problem-resolution solutions Our
    Web-architected applications can be deployed throughout the extended
    enterprise more quickly and cost effectively than traditional
    client/server products. Our products also enable our users to provide
    their customers enhanced around-the-clock Web-based self-service,
    reducing the overall cost of customer support. According to International
    Data Corporation, the cost of providing Web-based software support
    averages $0.45 per incident as compared to $30.00 for traditional phone
    support.
  . Providing scalable solutions for global organizations and their partners
    Our software has been deployed by one of our users to over 500 support
    engineers globally and is being used by that company to provide Web-based
    customer self-service support to over 130,000 registered end-users.
  . Leveraging investment in existing customer-support systems Our products
    integrate with most leading customer-relationship-management systems,
    increasing customer-support personnel productivity and customer
    satisfaction by reducing the need to re-gather existing customer
    information before proceeding to problem resolution.
 
  We market and sell our products primarily through a direct sales force. Our
customers include: 3Com, 3M, Amdahl, Compaq, EDS, EMC, Ericsson, Fujitsu,
Lucent, MCI/SHL Systemhouse, Microsoft, Motorola, Nortel Networks, Novell, NTT,
SGI, Softbank, Starbucks, Williams and Xerox.
 
 
  Our objective is to establish and maintain a leadership position in providing
Web-based problem-resolution software applications for the extended enterprise
and its customers. Our strategy to achieve this objective is to continue to
leverage the Internet, enhance our product suite, target additional vertical
markets, build additional strategic relationships and extend our solutions to
functional areas outside of customer support.

                                  RISK FACTORS
 
  You should carefully consider the risks described below before making an
investment decision. The risks and uncertainties described below are not the
only ones we face. If any of the following risks actually occur, our business,
financial condition or results of operations could be materially and adversely
affected. In such case, the trading price of our common stock could decline and
you may lose all or part of your investment.
 
We have incurred operating losses and we may not be profitable in the future
 
  We have incurred net losses in each quarter since inception and we expect to
continue to incur net losses for the foreseeable future. As of March 31, 1999,
we had an accumulated deficit of $33.4 million. We expect to continue to devote
substantial resources to expand our product development, sales and marketing
and client service groups. As a result, we will need to generate significant
revenues to achieve and maintain profitability. 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 results fluctuate from quarter to quarter
 
  Our license revenues have fluctuated substantially from quarter to quarter in
the past and are likely to continue to fluctuate substantially in the future.
Many of the factors causing the fluctuations are listed in "Management's
Discussion and Analysis of Financial Condition and Results of Operations--
Quarterly Results of Operations." In addition, the fiscal or quarterly budget
cycles of our users can cause our revenues to fluctuate from quarter to quarter
and applicable accounting policies may cause us to report new license
agreements as deferred revenue until implementation begins. As a result, 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. We will continue to base our decisions regarding our operating
expenses on anticipated revenue trends. To the extent these expenses are not
followed by increased revenues, our operating results will suffer. Fluctuations
in our operating results, particularly compared to the expectations of market
analysts or investors, could cause severe volatility in the price of our common
stock.
 
Our quarterly operating results depend on a small number of large orders
 
  We derive a significant portion of our product license revenue in each
quarter from a small number of relatively large orders. Our operating results
for a particular fiscal quarter could be materially adversely affected if we
are unable to complete one or more substantial license sales or implementations
planned for that quarter. During the last nine quarters, four or fewer
customers accounted for more than half of that quarter's total revenues. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations."
 
Quarter-to-quarter timing of our license revenue will sometimes vary based on
factors outside our control
 
  Under applicable accounting rules, we may experience further variability in
our license revenues from quarter to quarter due to factors outside our
control, including:
 
  . variability in the mix of new and existing customers
 
  . whether we are providing implementation services
 
  . whether implementation is delayed or takes longer than expected
 
                                       5
<PAGE>
 
  Where we are implementing the software, we will account for the agreement as
an item of deferred revenue and will recognize the revenue ratably over the
period of implementation. Most of our new customers begin implementation within
30 to 60 days of signing a license agreement. Once commenced, implementation of
our products typically ranges from 45 to 60 days. We can't, however, guarantee
that customers will begin implementation or that we will always be able to
implement our software within those time periods. Thus, all of our deferred
license revenue may not be recognized within the originally expected time
period. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
Our quarterly operating results may vary due to the effects of seasonality
 
  We expect to experience seasonality in our license revenue. To date, we
believe that seasonality has been masked by other factors, such as large orders
and the timing of personnel changes in our sales staff. Our customers' purchase
decisions are often affected by fiscal budgetary factors and by efforts of our
direct sales force to meet or exceed sales quotas. As a result, we expect new
business in the last quarter of a year to be greater than new business in the
first quarter of the following year. One effect of our revenue recognition
policy, however, is that revenue recognized in a quarter will typically not
reflect all of the new license agreements signed and shipped in that quarter.
Because revenue recognized in a given quarter may be primarily associated with
new business in prior quarters, revenue in the first quarter may be higher than
revenue recognized in the previous fourth quarter. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."
 
The limited sales history of our products makes it difficult to evaluate our
business and prospects
 
  We released our first SolutionSeries product in April 1995. As of March 31,
1999, approximately 40 companies licensed our SolutionSeries products.
Accordingly, the basis upon which you can evaluate our prospects in general,
and market acceptance of our products in particular, is limited. The market for
problem-resolution software will have to grow significantly, and we will have
to achieve broad market acceptance of our products, for our business to
succeed.
 
  Moreover, we released our Web-based products, SolutionPublisher and
SolutionExplorer, in August 1996 and November 1997, respectively. The limited
sales history of our Web-based products further limits your ability to evaluate
our business and prospects. Additionally, part of our strategy is to extend our
solutions to other functional areas where knowledge captured by our products
may be useful, such as product development, sales and marketing and field
service. Whether there will be significant demand for our products in these
areas is untested and uncertain.
 
We rely on sales of only one product family
 
  Product-license revenues and related services from our SolutionSeries
products accounted for substantially all of our total revenues during fiscal
1998, and we expect revenues from our SolutionSeries products to continue to
account for substantially all of our future revenues. As a result, factors
adversely affecting the demand for our SolutionSeries products, such as
competition, pricing or technological change, could materially adversely affect
our business, financial condition and operating results. Our future financial
performance will substantially depend on our ability to sell current versions
of the SolutionSeries products and our ability to develop and sell enhanced
versions of SolutionSeries products.
 
 
                                       6
<PAGE>
 
Our future success depends in part on broad market acceptance of the Web as a
delivery vehicle for problem resolution
 
  Part of our strategy is to continue to increase our focus on developing and
marketing Web-based products. Our Web-based products accounted for
approximately 33% of our software license revenue in 1998 and 51% in the first
quarter of 1999. Broad market acceptance of the Web as a delivery vehicle for
problem solutions to an enterprise's customers, resellers, channel partners and
field representatives through Web self-service is critical to the success of
our business. Thus, our future success substantially depends on continued
growth in the use of the Internet and the continued development of the Internet
as a viable commercial communication medium. We cannot be certain that
commercial Internet usage will continue to grow as it has in the past. If use
of the Internet as a commercial communication medium does not continue to grow
or evolves in a way that we cannot address, our business, financial condition
and operating results would be materially and adversely affected.
 
The usefulness of our product depends in part on factors outside our control
 
  The effectiveness of our SolutionSeries products depends in part on
widespread adoption and use of our software by customer-support personnel in
the extended enterprise and the quality of the solutions they generate. The
problem-resolution database is developed by customer-support personnel that
create solutions in the workflow and, sometimes, by importing a user's legacy
solutions. If customer-support personnel do not adopt and use our product,
necessary solutions will not be added to the database, and the database will be
inadequate. Some of our users have found that customer- support personnel
productivity initially drops while customer-support personnel become accustomed
to using our software. If an enterprise deploying our software has not
adequately planned for and communicated its expectations regarding that initial
productivity decline, customer-support personnel may resist adoption of our
software. In addition, if less-than-adequate solutions are created and left
uncorrected by a user's quality-assurance processes or if the legacy solutions
are inadequate, the database will similarly be inadequate, and the value of our
SolutionSeries products to our users will be impaired. Thus, successful
deployment and broad acceptance of our SolutionSeries products will depend in
part on whether our users effectively roll-out and use our software products
and the quality of the users' existing database of solutions, each of which are
outside our control. See "Business--Products."
 
Our market is highly competitive
 
  The market for our products is new and rapidly evolving, and is expected to
become increasingly competitive as current competitors expand their product
offerings and new companies enter the market. We face competition in the
problem-resolution software market primarily from:
 
  . other problem-resolution software vendors
 
  . e-commerce customer-management software vendors
 
  . our potential users' internal information technology departments, which
    may choose to rely upon their own proprietary problem-resolution systems
    or develop new proprietary systems
 
  As the market for problem-resolution software matures, it is possible that
new and larger companies will enter the market, existing competitors will form
alliances or current and potential competitors could acquire, be acquired by or
establish cooperative relationships with third parties. The resulting
organizations could have greater technical, marketing and other resources and
improve their products to address the needs of our existing and potential
users, thereby increasing their market
 
                                       7
<PAGE>
 
share. Increased competition could result in pricing pressures, reduced margins
or the failure of our products to achieve or maintain market acceptance. See
"Business--Competition."
 
We are currently dependent on Versant's database software
 
  We incorporate into our products a database licensed from Versant. We are
currently working on integrating our products with other databases, however we
do not believe that the integrations will be completed for at least three to
six months. Because our products currently rely on Versant's database, we
depend on Versant's ability to support the database in a timely and effective
manner. Until we finish integration of our products with other databases,
losing access to Versant's database would have a material adverse effect on our
ability to license our product to new users. See "Business--Products."
 
Our success depends on our ability to expand our sales and marketing
infrastructure
 
  To date, we have licensed our products primarily through our direct sales
force. Our vice president of sales began working for us in January 1999, and we
are currently seeking to hire a vice president of marketing. Our future revenue
growth will depend in large part on our ability to recruit, train and manage
additional sales and marketing personnel and expanding our indirect
distribution channels. We have experienced and continue to experience
difficulty in recruiting qualified sales and marketing 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. Our business, financial
condition and operating results will be materially adversely affected if we
fail to expand our sales and marketing resources. See "Business--Sales and
Marketing."
 
We may not be able to retain skilled technical personnel in a tight labor
market
 
  Qualified technical personnel are in great demand throughout the software
industry. The demand for qualified technical personnel is particularly acute in
the Pacific Northwest, due to the large number of software companies and the
low unemployment in the region. Our success depends in large part upon our
continued ability to attract and retain highly skilled technical employees,
particularly software architects and engineers. Our failure to attract and
retain the highly-trained technical personnel that are integral to our direct
sales, product-development and customer-support teams may limit the rate at
which we can generate sales and develop new products or product enhancements.
This could have a material adverse effect on our business, operating results
and financial condition.
 
We have recently added several new members to our management team
 
  In the last nine months we added three new members to our senior management
team, none of whom worked together prior to joining Primus. Our success depends
on the performance of our senior management and their ability to work together.
Failure to properly integrate them would harm our business. Much of our success
also depends on Michael A. Brochu, our president and chief executive officer.
The loss of Mr. Brochu's services would harm our business. See "Management."
 
We may be unable to expand our implementation and consulting capabilities,
either internally or by expanding relationships with systems integrators and
consulting firms
 
  If sales of new licenses increased rapidly or if we were to sign a license
agreement for a particularly large or complex implementation, our client
services personnel may be unable to meet
 
                                       8
<PAGE>
 
the demand for implementation services. In that case, if we were unable to
retain or hire highly trained consulting personnel or establish relationships
with third-party systems-integrators and consultants to implement our products,
we would be unable to meet customer demands for implementation and educational
services related to our products. A failure to do so could have a material
adverse effect on our business, operating results and financial condition. See
"Business--Strategy."
 
There are risks associated with our international operations
 
  Revenues from customers outside the United States represented approximately
$1.4 million in fiscal 1998, or 17% of our total 1998 revenues. A key component
to our business strategy is to expand our sales and support operations
internationally. Our international operations will continue to be subject to a
number of risks. These risks include:
 
  . costs of customizing products for foreign countries
 
  . laws and business practices favoring local competition
 
  . compliance with multiple, conflicting and changing laws and regulations
 
  . longer sales cycles
 
  . greater difficulty or delay in accounts receivable collection
 
  . import and export restrictions and tariffs
 
  . difficulties in staffing and managing foreign operations
 
  . political and economic instability
 
  Our international operations also face foreign-currency-related risks. To
date, substantially all of our revenues have been denominated in U.S. Dollars,
but we believe that in the future, an increasing portion of our revenues will
be denominated in foreign currencies, including the Euro, which was introduced
in January 1999. The Euro is an untested currency and may be subject to
economic risks that are not currently contemplated. Fluctuations in the value
of the Euro or other foreign currencies may have a material adverse effect on
our business, operating results and financial condition.
 
  We currently customize our products for the Japanese market. In the future,
we may develop additional localized versions of our products. Localization of
our products could create additional costs and cause delays in new product
introductions.
 
We must adapt to technology trends and evolving industry standards to remain
competitive
 
  Our market is susceptible to rapid changes due to technology innovation,
evolving industry standards, and frequent new service and product
introductions. New services and products based on new technologies or new
industry standards expose us to risks of technical or product obsolescence. We
will need to use leading technologies effectively, continue to develop our
technical expertise and enhance our existing products on a timely basis to
compete successfully in this industry. We cannot be certain that we will be
successful in using new technologies effectively, developing new products or
enhancing existing products on a timely basis or that any new technologies or
enhancements used by us or offered to our customers will achieve market
acceptance.
 
Continued integration of our products with other third-party software is
important to market acceptance of our product
 
  Our ability to compete successfully also depends on the continued
compatibility and interoperability of our products with products and systems
sold by various third parties, specifically
 
                                       9
<PAGE>
 
including customer-relationship-management software sold by Clarify, ONYX
Software, Remedy, Siebel Systems and Vantive. Currently, these vendors have
open applications program interfaces, which facilitate our ability to integrate
with their systems. If any one of them should close their programs' interface
or if they should acquire one of our competitors, our ability to provide a
close integration of our products could become more difficult and could delay
or prevent our products' integration with future systems.
 
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.
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. 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. A significant portion of our marks include the
word "Primus." Other companies use "Primus" in their marks alone or in
combination with other words, and we cannot prevent all third-party uses of the
word "Primus." We license certain trademark rights to third parties. Such
licensees may not abide by compliance and quality control guidelines with
respect to such trademark rights and may take actions that would adversely
affect our trademarks.
 
Other companies may claim that we infringe their intellectual property or
proprietary rights
 
  If any of our products violate third party proprietary rights, we may be
required to reengineer our products or seek to obtain licenses from third
parties, and such efforts may not be successful. We do not conduct
comprehensive patent searches to determine whether the technology used in our
products infringes patents held by third parties. Product development is
inherently uncertain in a rapidly evolving technological environment in which
there may be numerous patent applications pending, many of which are
confidential when filed, with regard to similar technologies. In addition,
other companies have filed trademark applications for marks similar to the
names of our products. Although we believe that our products do not infringe
the proprietary rights of any third parties, third parties could assert
infringement claims against us in the future. The defense of any such claims
would require us to incur substantial costs and would divert management's
attention and resources to defend against any claims relating to proprietary
rights, which could materially and adversely affect our financial condition and
operations. Parties making such claims could secure a judgment awarding them
substantial damages, as well as injunctive or equitable relief that could
effectively block our ability to sell our services. Any such outcome could have
a material adverse effect on our business, financial condition and operating
results.
 
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
 
                                       10
<PAGE>
 
able to [influence][control] all matters requiring shareholder approval and,
thereby, our management and affairs. Some matters that typically require
shareholder approval include:
 
  . election of directors
 
  . certain amendments to our articles of incorporation
 
  . merger or consolidation
 
  . 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."
 
Management has broad discretion in using the proceeds from this offering
 
  We have not identified specific uses for the proceeds from this offering, and
we will have broad discretion in how we use them. See "Use of Proceeds."
 
Our articles of incorporation and bylaws and Washington law contain provisions
that could discourage a takeover
 
  Certain provisions of our articles of incorporation and our bylaws and
Washington law could make it more difficult for a third party to obtain control
of Primus, which could reduce the market price of our stock. 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 shares of common stock outstanding after this offering
will be available for sale in the public market as follows:

Year 2000 remediation may involve significant time and expense and may reduce
our future sales
 
  Many currently installed computer systems are not capable of distinguishing
21st century dates from 20th century dates or have been programmed with default
dates ending in "99," the common two-digit reference for 1999. As a result, as
we transition from the 20th century to the 21st century, 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
 
                                       11

information correctly. Although we believe the current versions of our software
products are Year 2000 compliant, we may face claims based on Year 2000 issues
arising from the integration of multiple products within an overall system. We
may also experience reduced sales of our products as potential customers reduce
their budgets or delay new purchases for customer-support software due to
increased expenditures on their own Year 2000 compliance efforts. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Year 2000 Compliance."
 
Changes in accounting standards could affect the calculation of our future
operating results
 
  In October 1997, the American Institute of Certified Public Accountants
issued its Statement of Position 97-2, "Software Revenue Recognition," and
later amended its position by its Statement of Position 98-4. We adopted
Statement of Position 97-2 effective January 1, 1998. Based on our
interpretation of the AICPA's position, we believe our current revenue
recognition policies and practices are consistent with Statement of Position
97-2 and Statement of Position 98-4. The AICPA has also issued Statement of
Position 98-9, which is effective for transactions we enter into beginning
January 1, 2000. However, full implementation guidelines for these standards
have not yet been issued. Once available, such implementation guidelines could
lead to unanticipated changes in our current revenue accounting practices which
could materially adversely affect our business, financial condition and
operating results. Additionally, the accounting standard setters, including the
Securities and Exchange Commission and the Financial Accounting Standards
Board, are reviewing the accounting standards related to stock-based
compensation. Any changes to this standard or any other accounting standards
could materially adversely affect our business, financial condition and
operating results. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."
 
You should not unduly rely on forward-looking statements
 
  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 above and elsewhere
in this prospectus.

                                USE OF PROCEEDS
 
  We expect to receive approximately $      million in net proceeds from the
sale of the            shares of common stock in this offering, at the assumed
initial public offering price of $      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 our 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 oral or written plans, agreements or commitments
to do so, and are not currently negotiating any such acquisition or joint
venture. The amounts that we actually expend for working capital purposes and
capital expenditures 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 allocating 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 facilities
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 on an as-if-converted basis, as adjusted assuming the cash exercise of
the warrants referred to below.
 
  Our pro forma net tangible book value at March 31, 1999, after giving effect
to (1) the conversion of all outstanding preferred stock into 4,966,660 shares
of common stock upon the closing of this offering and (2) proceeds from the
exercise of warrants to purchase 66,389 shares of common stock at a weighted-
average exercise price of $4.10 per share, was $327,000, or $0.03 per share of
common stock. After giving effect to the sale of the      shares of common
stock at the assumed initial public offering price of $     per share (less
anticipated underwriting discounts and commissions and estimated expenses we
expect to pay in connection with this offering), our pro forma as adjusted net
tangible book value at March 31, 1999 would have been $    , or $     per
share. This represents an immediate increase in the 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 initial
public offering price of $     per share.
 
  The following table illustrates this per share dilution:

  We also have available 1,166,667 shares for grant under our 1999 stock plan
and 600,000 shares for issuance under our 1999 employee stock purchase plan. To
the extent the option holders exercise outstanding options, or any options we
grant in the future, there will be further dilution to new investors. Both of
these plans have provisions to automatically add shares to the plan in certain
circumstances. In April, we reserved an additional 500,000 shares under our
1995 plan.

                    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 unduly rely 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
 
  Our predecessor, Symbologic Corporation, incorporated in October 1986 and
initially focused on a software development tool for creation of systems to
gather organizational expertise. In 1992, we licensed that product line to
another company and founded the Customer Support Consortium, a consortium of
leading software and hardware companies focused on advancing customer-support
strategies, models and standards. From 1992 to 1995, we directed our attention
to customer-support products and began developing our SolutionSeries products.
In 1995, we changed our name to Primus and released SolutionBuilder, our first
SolutionSeries product. We launched our first Web-based products,
SolutionPublisher and SolutionExplorer, in 1996 and the end of 1997,
respectively. In 1997, we also divested our interest in the Customer Support
Consortium in conjunction with its transition to an independent nonprofit
entity.
 
  Our revenues, which consist of software license revenues and related client
services revenues, totaled $2.4 million, $5.2 million and $8.6 million in 1996,
1997 and 1998, respectively. For the foreseeable future, we expect
substantially all of our revenues will continue to be derived from our
SolutionSeries product family and related services. We market our software and
services through our direct sales organization in the United States and the
United Kingdom. In Japan, Primus KK, a Japanese joint venture in which we hold
a 14.3% minority interest, distributes our products. Our international sales
constituted 17% of our 1998 revenues and 36% of our revenues for the first
quarter of 1999. We believe that international revenues, as a percentage of our
total revenues, will vary substantially on a quarterly basis for the forseeable
future.
 
  We price our software licenses based on the number of servers, users and/or
concurrent users. From time to time, we grant discounts to customers with large
installations or who license several SolutionSeries products concurrently.
 
  Our service revenues consist of consulting, training and maintenance and
support fees. We provide consulting and training services relating to our
products on a time-and-materials basis under installation services agreements
with our customers. We provide maintenance and support services to our
customers under renewable one-year maintenance and support agreements, which we
price as a percentage of our license fees.
 
  Before 1998, we recognized software license revenue in accordance with the
American Institute of Certified Public Accountants Statement of Position 91-1.
Beginning in 1998, we have recognized software license revenue in accordance
with AICPA Statement of Position 97-2, "Software Revenue Recognition," and
related amendment and interpretations contained in the AICPA's Statement of
Position 98-4. We typically recognize software license revenues over the
software implementation period if:
 
  . we have signed a noncancelable license agreement with a customer
 
  . we have shipped the software
 
                                       17
<PAGE>
 
  . the fee is fixed and determinable
 
  . there is sufficient vendor-specific objective evidence to support
    allocation of the total fee to all elements of multiple-element
    arrangements
 
  . the fee is collectible
 
We currently recognize license revenue over the implementation period if
implementation services are included in the original license arrangement. As a
result, even where we have a signed license agreement for the purchase of our
software and have shipped the software, license revenue recognition depends on
whether we have begun implementation. While implementation services are not
essential to the functionality of our software, due to the relatively recent
introduction of our product line, our desire to ensure customer satisfaction
while we seek to build market share, the limited number of installations of our
products to date and the limited number of third-party vendors that currently
provide implementation services, we have concluded that revenue recognition
over the implementation period is appropriate. Consequently, we account for
agreements for which we have agreed to provide implementation as an item of
deferred revenue and recognize the revenue ratably over the period of
implementation. On the other hand, for license agreements under which we have
no implementation responsibility, we generally recognize revenue from the
agreement upon shipping the software, which we typically accomplish shortly
after signing a license agreement.
 
  For new users, we typically agree to implement our software. Conversely,
examples of situations under which we have no implementation responsibility
would include a license agreement to add users for an existing customer or a
license agreement with a new customer who is using an outside implementation
service provider or is relying on its own internal implementation services.
Most of our new customers begin implementation within 30 to 60 days of signing
a license agreement. Once commenced, implementation of our products typically
ranges from 45 to 60 days.
 
  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 users of our products.
 
  We believe our current revenue-recognition policies and practices are
consistent with applicable AICPA accounting pronouncements; however, the AICPA
has not issued full interpretation guidelines for its latest standards yet. We
might find it necessary to change our current revenue accounting practices once
the AICPA issues its interpretation guidance. Any changes in revenue-
recognition policies could result in substantial changes in the timing of our
future revenues and earnings. The AICPA recently issued its Statement of
Position 98-9, which provides certain amendments to its Statement of
Position 97-2 and is effective for transactions entered into beginning January
1, 2000. We do not expect implementation of this latest AICPA pronouncement to
materially impact our revenue recognition practices.
 
  Since 1992, we have invested heavily in product development and in building
our sales, marketing and client services organizations. From November 1997
through February 1999, we made a strategic investment in building our executive
management team to help us execute our long-term growth strategy. We have
incurred quarterly net losses since inception, and as of March 31, 1999, had an
accumulated deficit of $33.4 million. We anticipate that our operating expenses
will continue to increase substantially for the foreseeable future as we
continue to expand our product development, sales and marketing and client-
services staff.

Revenues
 
  We derive our revenues from the sale of software products and related
services including support and maintenance contracts. Revenues were $1.4
million and $3.9 million for the three months ended March 31, 1998 and 1999,
respectively, representing an increase in the first quarter of 1999 of $2.5
million or 187% over the comparable quarter of the prior year. Revenues were
$2.4 million, $5.2 million and $8.6 million in 1996, 1997 and 1998,
respectively, representing increases of $2.8 million or 114% from 1996 to 1997
and $3.4 million or 66% from 1997 to 1998. During 1996 and 1997, no single
customer accounted for 10% or more of total revenues. Purchases by one
customer, 3Com, represented 12% of our 1998 revenues.
 
  License Revenue. License revenues were $948,000 and $2.9 million for the
three months ended March 31, 1998 and 1999, respectively, representing an
increase in the first quarter of 1999 of $2.0 million or 206% over the
comparable quarter of the prior year. The increase was due to increased market
acceptance of our SolutionSeries products, increased international sales and
increases in both the size and productivity of the sales force. License
revenues were $1.5 million, $3.6 million and $6.0 million in 1996, 1997 and
1998, respectively, representing increases of $2.1 million, or 144%, from 1996
to 1997 and $2.5 million, or 70%, from 1997 to 1998. The increase from 1996 to
1997 was primarily a result of increased market acceptance of SolutionBuilder
and introduction of SolutionPublisher in August 1996. The increase from 1997 to
1998 primarily
 
                                       19
<PAGE>
 
resulted from introduction of SolutionExplorer in November 1997, the increased
size of our sales force and increased international sales, as a result of the
opening of our U.K. sales office and sales through our Japanese distributor.
 
  Service Revenue. Service revenues were $417,000 and $1.0 million for the
three months ended March 31, 1998 and 1999, respectively, representing an
increase in the first quarter of 1999 of $593,000, or 142%, over the comparable
quarter of the prior year. Service revenues were $963,000, $1.6 million and
$2.6 million in 1996, 1997 and 1998, respectively, representing increases of
$668,000, or 69%, from 1996 to 1997 and $945,000, or 58%, from 1997 to 1998.
All of the increases resulted primarily from increases in purchases of
maintenance and support contracts by our growing installed customer base and
consulting fees attributable to an increased number of implementations. We
expect the proportion of service revenues to total revenues to fluctuate in the
future, depending in part on use of third-party consulting and implementation
service providers.
 
Cost of Revenues
 
  Cost of License Revenue. Cost of license revenue includes royalties and fees
paid to third parties under license arrangements and costs related to media and
duplication for our products and manuals. Cost of license revenues were $12,000
and $145,000 for the three months ended March 31, 1998 and 1999, respectively,
and $137,000, $317,000 and $348,000 in 1996, 1997 and 1998, respectively. The
cost of licenses increased $133,000, or 1,108%, from the three months ended
March 31, 1998 to the three months ended March 31, 1999, and $180,000, or 131%,
from 1996 to 1997, and $31,000, or 10%, from 1997 to 1998. Cost of licenses as
a percentage of license revenues were 1.3% and 5.0% for the three months ended
March 31, 1998 and 1999, respectively, and 9.4%, 8.9% and 5.8% for 1996, 1997
and 1998, respectively. We anticipate that our cost of license revenue will
continue to increase in absolute dollars. Our cost of license revenue as a
percent of license revenue has varied in the past due to the volume of product
sales and the type of the royalty agreements in place at the time.
 
  Cost of Service Revenue. Cost of service revenue includes personnel and other
costs related to professional services and customer support. Cost of service
revenue were $526,000 and $790,000 for the three months ended March 31, 1998
and 1999, respectively, and $1.1 million, $2.1 million and $2.5 million in
1996, 1997 and 1998, respectively. Cost of service revenue increased $264,000,
or 50%, from the three months ended March 31, 1998 to the three months ended
March 31, 1999, and $996,000, or 91%, from 1996 to 1997, and $375,000, or 18%,
from 1997 to 1998. The increases in cost of service revenue from 1996 to the
first quarter of 1999 was a result of hiring and training a consulting
organization to successfully implement our SolutionSeries products. Cost of
service revenue as a percentage of service revenues were 126% and 78% for the
three months ended March 31, 1998 and 1999, respectively, and 113%, 128% and
95% for 1996, 1997 and 1998, respectively. The decrease in cost of service
revenues as a percentage of services revenues from the first quarter of 1998 to
the first quarter of 1999 was primarily due to higher utilization rates as a
result of higher levels of consulting-services activity and increased
experience of the customer-support personnel.
 
Operating Expenses
 
  Sales and Marketing. Sales and marketing expenses consist primarily of
salaries, bonuses and commissions earned by sales and marketing personnel,
travel and costs associated with marketing programs, such as trade shows,
public relations and new product launches. Sales and marketing
 
                                       20
<PAGE>
 
expenses were $1.3 million and $2.9 million for the three months ended March
31, 1998 and 1999, respectively, and $3.5 million, $4.6 million and $9.8
million in 1996, 1997 and 1998, respectively. Sales and marketing expenses
increased $1.6 million, or 127%, for the three months ended March 31, 1998 as
compared to the three months ended March 31, 1999, and $1.1 million, or 32%,
from 1996 to 1997, and $5.1 million, or 111%, from 1997 to 1998. The increase
from 1996 to the first quarter of 1999 resulted primarily from the hiring of
sales management, sales representatives, sales engineers and marketing
personnel, as well as higher commissions paid as a result of revenue growth.
Sales and marketing employees totaled 30 and 58 as of March 31, 1998 and 1999,
respectively, and 23, 24 and 52 at December 31, 1996, 1997 and 1998,
respectively. The launch of our U.K. office in August 1998 contributed to the
increase of sales and marketing headcount that year. Sales and marketing
expenses as a percentage of total revenues were 93% and 74% for the three
months ended March 31, 1998 and 1999, respectively, and 144%, 89% and 113% for
1996, 1997 and 1998, respectively. The increase in sales and marketing expense
as a percentage of total revenues from 1997 to 1998 was due to headcount
growth, attributable in part to the launch of our U.K. office. We believe that
a significant increase in our sales and marketing efforts is essential for us
to maintain market position and further increase market acceptance of our
products. Accordingly, we anticipate that we will continue to invest
significantly in sales and marketing for the foreseeable future, and the dollar
amount of sales and marketing expenses will increase in future periods.
 
  Research and Development. Research and development expenses consist primarily
of salaries and benefits for software developers, product managers and quality
assurance personnel and payments to outside contractors. Research and
development expenses were $713,000 and $1.1 million for the three months ended
March 31, 1998 and 1999, respectively, and $2.5 million, $2.5 million and $3.3
million in 1996, 1997 and 1998, respectively. Research and development expenses
increased $352,000, or 49%, from the three months ended March 31, 1998 to the
three months ended March 31, 1999, $79,000, or 3%, from 1996 to 1997 and
$748,000, or 30%, from 1997 to 1998. The increases from 1997 to the three
months ended March 31, 1999 were primarily due to increased hiring of software
developers and quality-assurance staff to support development of our new
products and enhancements to our existing products and to an increase in
compensation levels for development and quality-assurance personnel. Research
and development personnel totaled 28 and 38 as of March 31, 1998 and 1999,
respectively, and 24 and 31 for 1997 and 1998, respectively. Research and
development expenses as a percentage of total revenues were 52% and 27% for the
three months ended March 31, 1998 and 1999, respectively, and 102%, 49% and 38%
for 1996, 1997 and 1998, respectively. We believe that a significant increase
in our research and development investment is essential for us to maintain our
market position, to continue to expand our product line and to develop
additional applications for our associative-based technology. Accordingly, we
anticipate that we will continue to invest significantly in product research
and development for the foreseeable future, and research and development
expenses are likely to increase in future periods. In the development of our
new products and enhancements of existing products, the technological
feasibility of our software is not established until substantially all product
development is complete. Accordingly, software development costs eligible for
capitalization were insignificant, and all costs related to internal research
and development have been expensed as incurred.
 
  General and Administrative. General and administrative expenses consist
primarily of salaries, benefits and related costs for executive, finance,
administrative and information services personnel. General and administrative
expenses were $460,000 and $879,000 for the three months ended March 31, 1998
and 1999, respectively, and $1.2 million, $1.6 million and $3.3 million in
1996, 1997 and 1998, respectively. General and administrative expenses
increased $419,000, or 91%, from
 
                                       21
<PAGE>
 
the three months ended March 31, 1998 to the three months ended March 31, 1999,
and $351,000, or 29%, from 1996 to 1997, and $1.7 million, or 107%, from 1997
to 1998. The increase from 1996 to the first quarter of 1999 was primarily the
result of our hiring additional executive, finance, and administrative
personnel to support the growth of our business during these periods. The
increase in general and administrative expenses from 1997 to 1998 also reflects
an increase in reserve accounts, such as in the allowance for doubtful accounts
related to our increase in revenues. General and administrative expenses as a
percentage of total revenues were 34% and 22% for the three months ended March
31, 1998 and 1999, respectively, and 51%, 30% and 38% for 1996, 1997 and 1998,
respectively. The increase in general and administrative expenses as a
percentage of total revenues from 1997 to 1998 was primarily due to growth in
administrative headcount as we added to our executive team. We believe that our
general and administrative expenses will continue to increase as a result of
the continued expansion of our administrative staff and the 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.
 
  Income Taxes. As of December 31, 1998, we had net operating loss
carryforwards for federal and state income tax reporting purposes of
approximately $24.8 million and research and development tax credit
carryforwards of $418,000, which begin to expire in 2001, if not utilized. The
Internal Revenue Code contains provisions that limit the use in any future
period of net operating loss and credit carryforwards upon the occurrence of
certain events, including significant change in ownership interests. We had
deferred tax assets, including our net operating loss carryforwards and tax
credits, totaling approximately $10.9 million as of December 31, 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 6 of the
notes to our consolidated financial statements.

  The trends discussed above in the annual and quarterly comparisons of
operating results generally apply to the comparison of operating results for
the five quarters in the 15-month period ended March 31, 1999. General and
administrative expenses for the fourth quarter of 1998 were significantly
higher than prior periods primarily due to year-end compensation accruals and
increases in reserve accounts, such as our allowance for doubtful accounts
related to our increase in revenues. 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. We expect to experience seasonality with respect to software license
revenues. To date, we believe that seasonality has been masked by other
factors, such as the impact of large transactions and personnel changes.
 
  We believe that our period-to-period operating results are not meaningful,
and you should not rely on them as indicative of our future performance. You
should also evaluate our prospects in light of the risks, expenses and
difficulties commonly encountered by comparable early-stage companies in new
and rapidly emerging markets. We can't assure you that we will successfully
address the risks and challenges that face us. In addition, although we have
experienced significant revenue growth recently, we can't assure you that our
revenue will continue to grow or that we will become or remain profitable in
the future. 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 versus indirect license revenues
 
  . variability in the mix of services that we perform versus those performed
    for our customers by others
 
  . success in expanding our direct sales force and indirect distribution
    channels
 
  . 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
 
  . the loss of any key employees and timing of our new hires
 
Liquidity and Capital Resources
 
  Since our inception, we have primarily financed our operations through the
private sale of our equity securities, resulting in net proceeds of $33.5
million through March 31, 1999. To a lesser extent, we have financed our
operations through equipment financing and traditional lending arrangements.
 
  As of March 31, 1999, we had cash and cash equivalents of $2.4 million, a
decrease from $2.6 million of cash and cash equivalents held as of December 31,
1998. Our working capital deficit at March 31, 1999 was $1.1 million, compared
to working capital deficit of $216,000 at December 31, 1998. The increase in
the working capital deficit is attributable to a $2.0 million decrease in cash
and securities available-for-sale and accounts receivable, offset by a $1.4
million
 
                                       24

decrease in current liabilities during the first quarter of 1999. As of March
31, 1999, working capital excluding deferred revenue was $5.6 million compared
to $7.4 million at December 31, 1998.
 
  As of March 31, 1999, we had $1.6 million outstanding under a senior term-
loan facility with Imperial Bank that bears interest at a rate equal to the
bank's prime rate plus 1%, which equaled 8.75% as of March 31, 1999. In April
1999, we entered into a $5.0 million working-capital revolving line of credit
with Imperial Bank that is secured by our accounts receivable and bears
interest at the bank's prime rate plus .75%, which was 8.5% as of March 31,
1999. This facility allows us to borrow up to the lesser of 80% of our eligible
accounts receivable or $5 million. The facility will expire in April 2000. In
April 1999, we also obtained a $1.0 million capital-equipment line of credit
with Imperial Bank that bears interest at a rate equal to the bank's prime rate
plus 1.0%, which equaled 8.75% as of March 31, 1999. All of our lending
facilities require us to maintain certain financial covenants, including
requirements that we maintain certain financial ratios. We were in compliance
with or received waivers of all of these financial covenants at March 31, 1999.
 
  Our operating activities resulted in net cash outflows of $674,000 and $2.2
million for the three months ended March 31, 1998 and March 31, 1999,
respectively. The increase in operating cash outflows from the three months
ended March 31, 1998 to the three months ended March 31, 1999 was due primarily
to a decrease in deferred revenues and accounts payable. Operating activities
resulted in net cash outflows of $6.4 million in 1996, $3.1 million in 1997,
and $7.5 million in 1998. The decrease in operating cash outflows from 1996 to
1997 was attributable primarily to an increase in deferred revenues. The
increase in operating cash outflows from 1997 to 1998 resulted from further
operating losses and growth in accounts receivable, partially offset by further
increases in deferred revenues.
 
  Investing activities provided cash of $412,000 and $921,000 for the three
months ended March 31, 1998 and March 31, 1999, respectively. In addition,
investing activities used cash of $1.2 million in 1996, $490,000 in 1997 and
$3.3 million in 1998 primarily for the purchase of capital equipment and short-
term securities.
 
  Financing activities provided cash of $36,000 and $1.2 million for the three
months ended March 31, 1998 and March 31, 1999, respectively. Financing
activities provided cash of $9.4 million in 1996, $2.3 million in 1997 and
$12.7 in 1998 primarily through the issuance of preferred stock and proceeds
from the exercise of stock options, partially offset by payments on capital
equipment lease 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
 
  . 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, and available bank borrowings, will be sufficient to meet our
 
                                       25
<PAGE>
 
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 obtain may dilute your ownership interest in
Primus.
 
Year 2000 Compliance
 
  Many currently installed computer systems are not capable of distinguishing
21st century dates from 20th century dates or have been programmed with default
dates ending in "99," the common two-digit reference for 1999. As a result, as
we transition from the 20th century to the 21st century, 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. We
recognize the need to ensure our operations will not be adversely affected by
Year 2000 software failures.
 
  In September 1998, we established a Year 2000 compliance task force, composed
of high-level representatives from the product development, information systems
and legal departments. The task force is responsible for formulating and
implementing our Year 2000 readiness and has applied a phased approach to
analyzing our operations and relationships as they relate to the Year 2000
problem.
 
  We have completed our initial assessment of the potential overall impact of
the impending century change on our business, financial condition and operating
results. Based on our current assessment, we believe the current versions of
our software products are Year 2000 compliant. By Year 2000 compliant, we mean
that our software products, when used with accurate date data and in accordance
with their associated documentation, are capable of properly processing date
data from, into and between the 20th and 21st centuries, including the years
1999, 2000 and leap years, provided that all other products (e.g., hardware,
software and firmware) used with our products properly exchange date data with
them. However, our products are generally integrated into enterprise systems
involving sophisticated hardware and complex software products that we cannot
adequately evaluate for Year 2000 compliance. 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 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 and
as they delay purchase of new systems that may not be Year 2000 compliant.
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.
 
                                       26
<PAGE>
 
  We have reviewed our internal management information and other critical
business systems to identify any Year 2000 problems. We also have communicated
with the external vendors that supply us with material software and information
systems and with our significant suppliers to determine their Year 2000
readiness. In the course of these investigations, we have not encountered any
material Year 2000 problems with these third-party products.
 
  In September 1998, we had a firm of independent consultants undertake an
assessment of our Year 2000 readiness, at a cost of $6,000. To date, apart from
that assessment, we have not incurred any material costs directly associated
with our Year 2000 compliance efforts, except for compensation expense
associated with our salaried employees who have devoted some of their time to
our Year 2000 assessment and remediation efforts. We do not expect the total
cost of Year 2000 problems to be material to our business, financial condition
and operating results. However, during the months prior to the century change,
we will continue to evaluate new versions of our software products, new
software and information systems provided to us by third parties and any new
infrastructure systems that we acquire to determine whether they are Year 2000
compliant. Despite our current assessment, we may not identify and correct all
significant Year 2000 problems on a timely basis. Year 2000 compliance efforts
may involve significant time and expense and unremediated problems could
materially adversely affect our business, financial condition and operating
results. We currently have no contingency plans to address the risks associated
with unremediated Year 2000 problems.

Overview
 
  We are a leading provider of Web-based problem-resolution software for
customer support and self-service. Our applications enable businesses to
capture problem-resolution information, solve customer problems, reuse
solutions stored in the knowledge base and share captured knowledge throughout
the extended enterprise. Our SolutionSeries family of software products
enhances an organization's problem-resolution capabilities by using our
associative problem-solving technology and leveraging the Internet to extend
customer support to remote employees, business partners and end-user customers.
 
  We believe our software allows organizations to improve customer satisfaction
levels and decrease support costs by:
 
  . reducing the overall time needed to resolve problems
 
  . improving first-call resolution rates
 
  . reducing escalation of problems to senior analysts
 
  . reducing training time
 
  . increasing call deflections to the Web
 
  . increasing solution reuse
 
Industry Background
 
  During the last several years, many businesses have found that providing
responsive and accurate answers to their customers' questions and problems has
become a crucial business function. As products and services have become more
standardized, customer support and problem resolution have become increasingly
important competitive differentiators. Furthermore, the growth of Internet-
based electronic commerce has facilitated the purchasing and ordering process
and enabled an efficient but less personal relationship between merchant and
customer. As a result, customer support has often become the primary point of
customer contact and can significantly influence customer loyalty.
 
  Customer support is increasingly challenging
 
  While recognizing the importance of quality customer support, most
organizations have been challenged by increasing product and distribution-
channel complexity and by rising customer expectations.
 
Product complexity             Products and services are increasingly complex
                               in today's marketplace, driven primarily by:
 
                                   . Proliferation of technology-based
                                     products and services
 
                                   . Increasing integration of products and
                                     components from several manufacturers
 
                                   . High rates of innovation and product
                                     change
 
                               Each of these factors threaten an enterprise's
                               ability to provide quality customer service and
                               manage costs, since they can contribute to
                               longer time needed to resolve problems and
                               lower first-call resolution rates.
 
                                       28

                               As product innovation continues to shorten
                               product lifecycles, as well as open new markets
                               for technology-based products, these challenges
                               will be heightened. Customers will need more
                               product education and support. Historically,
                               businesses have responded to the increased
                               demand by adding headcount to their customer
                               support organizations. However, current
                               shortages of qualified customer-support
                               personnel, high turnover in customer-support
                               departments and the increasing cost of training
                               customer-support personnel have made adding
                               headcount less effective.
 
Distribution-channel           As traditional wholesale-retail-consumer
 complexity                    business models expand to include resellers,
                               systems integrators, outsourcers and channel
                               partners, enterprises are facing difficult
                               challenges in enabling their business partners
                               to provide high-quality, consistent customer
                               support. Without access to a collaborative
                               system that allows them to share important
                               problem-resolution information, partners in the
                               extended business enterprise may provide
                               inconsistent solutions or redirect their
                               customers' problems to the enterprise.
 
Increasing customer            Many companies have found that their customers
 expectations                  increasingly want to be able to resolve
                               customer problems in a fast, convenient manner
                               at any time of the day or night. Customers also
                               expect to be able to use their choice of
                               medium: telephone, fax, email or the Internet.
                               The Aberdeen Group estimates that, by 2002,
                               companies will receive over 50% of all general
                               customer support contacts and inquiries over
                               the Web and through email messages and other
                               Web-based forms. These increasing demands have
                               led some companies to hire more customer-
                               support personnel to provide around-the-clock
                               customer support. Others have sought to meet
                               this challenge by investing in technology to
                               increase their customer-support capabilities.
 
  Traditional customer-support responses have been inadequate
 
  Many businesses have provided customer-support and problem resolution through
a call center. Software systems designed to support customer call centers
traditionally include call-routing, call-tracking and customer-relationship-
management systems. These systems are effective at directing customer calls on
a timely basis to the appropriate customer-support personnel together with the
related customer information. They do not, however, help support analysts
become more effective problem solvers or enable them to capture and share
valuable knowledge gained from understanding and solving the customer's
problems. According to a 1995 survey by Andersen Consulting, call tracking
accounted for only 20% of the total cost of a call, with 62% of the total costs
relating to problem solving and the balance attributable to administrative
costs.

  To better address the need for improved problem-resolution capabilities,
businesses have considered a variety of alternatives including increasing
staffing, developing their own problem-resolution systems and buying problem-
resolution solutions from third-party software vendors. Increased hiring is an
expensive alternative that provides little leverage or scalability. Development
of custom solutions can detract the business from its core competencies and
prove costly to develop and maintain. Software vendors focused on providing
problem-resolution systems have developed various approaches to enable
businesses to manage problem-resolution information.
 
  Traditionally, third-party systems have incorporated enhanced text-retrieval,
decision-tree or case-based-reasoning technology.
 
Enhanced text-retrieval        Enhanced text-retrieval systems use key-word
systems                        searches to locate words, phrases and concepts
                               within documents and files. These systems then
                               retrieve and rank the findings according to the
                               frequency with which the search terms occur.
                               Text-retrieval systems are of limited use in
                               real-time problem solving, since they require
                               the user to know the exact words used by the
                               systems developer to label a particular
                               concept. They tend to return too much
                               irrelevant information and do little or nothing
                               to enable the capture of new solutions to
                               customer problems.
 
Case-based-reasoning and
decision tree systems
                               Case-based-reasoning and decision tree systems
                               typically require a customer-support analyst to
                               follow a fixed question-and-answer sequence to
                               arrive at a pre-engineered solution. These
                               systems work best in reasonably stable
                               environments in which problems can be
                               anticipated and their solutions pre-engineered.
                               For organizations with quickly changing
                               product-support requirements, these systems
                               often prove to be costly and time consuming to
                               develop. Furthermore, since the solution to a
                               problem is not captured in the product's
                               workflow, it is similarly expensive and time
                               consuming to maintain the database. For
                               instance, for each "new" solution an analyst
                               uncovers, a complete description needs to be
                               submitted to a knowledge engineer, who then
                               must redesign the cases or the decision trees
                               and enter this into the database. In the
                               meantime, many problems have to be re-solved
                               from the start, since the system does not
                               automatically capture the solution. Finally,
                               since these approaches are rigid by nature, the
                               methodologies generally take a long time to
                               resolve complex problems that require several
                               levels of questioning, do not provide guidance
                               toward solving subsequent problems if no
                               solution is found the first time and do not
                               effectively leverage the experience of more
                               senior personnel.

  Associative problem solving: a better problem-solving methodology
 
  We believe that, over the past few years, problem-resolution systems based on
associative problem-solving technology have gained increasing acceptance by
addressing the shortcomings associated with text-retrieval, decision-tree and
case-based-reasoning systems. Associative problem-solving technology uses
natural-language statements to describe the support problem, including symptoms
of the problem, facts about the environment in which the problem arose and
recent changes to that environment. These systems treat natural-language
statements as concepts and search for relevant solutions using algorithms that
leverage the associations that exist among each of the many concepts in the
knowledge database. As a result, these systems enable users to locate, evaluate
and return solutions with a high degree of relevance.
 
  The combination of natural-language support and the associative search
methodology helps these systems to support multiple approaches to problem
solving. For example, a more senior analyst, who may know many of the potential
solutions based on his or her experience, will be able to leverage that
experience to find the relevant solution quickly by describing only the most
relevant facts and symptoms. A less experienced junior analyst, on the other
hand, can learn how to better solve customer problems through use of the system
by seeing which problem-description elements provide key clues to the solution.
Non-technical users benefit from the natural-language interface, which allows
them to describe their problems without needing to know the technical jargon
that a software engineer may have used to describe the problem in the knowledge
database. Associative problem-solving systems are therefore well suited to
provide self-service customer support through the Internet.
 
  Associative problem-solving systems also enhance a customer-support
organization's ability to capture solutions without the costly and time-
consuming task of off-line development and maintenance of the knowledge
database. For example, when information returned in response to the problem
description does not solve the customer's problem, associative problem-solving
systems enable the customer-support personnel to create and capture new
solutions in their workflow. By enabling customer-support organizations to
capture solutions on a real-time basis, the need for off-line knowledge
engineering is minimized and the number of solutions that get created more than
once is reduced.
 
  The Internet provides an opportunity to improve support levels and reduce
support costs
 
  Internet technology has allowed many organizations to re-engineer their call
centers into customer-contact centers. Customer-contact centers are now being
designed to allow for multiple channels of customer contact, including
telephone, fax, email and the Web. Integrating the support capabilities of the
customer-contact center with a business's Web site presents an opportunity to
increase customer-service levels and reduce costs.
 
  By incorporating problem-resolution technology in its Web-site architecture,
an enterprise can provide its customers with around-the-clock access to
customer support, thereby improving customer-satisfaction levels. An enterprise
can also reduce the overall cost of customer support and increase the
scalability of its customer-support operations by inducing more customers to
first seek support from the enterprise's Web site, rather than the more costly
customer-call center. According to International Data Corporation, the cost of
providing Web-based software support averages $0.45 per incident as compared to
$30.00 per incident for traditional phone support. To date, many companies have
handled the growing number of support inquiries over the Web by posting static
responses to
 
                                       31
<PAGE>
 
a frequently asked questions on their Web sites or through automating responses
to incoming inquiries with pre-scripted email responses. Both of these
approaches are limited in their ability to effectively handle unique incoming
customer inquiries.
 
  Finally, businesses can also use Internet technologies to deploy Web-based
problem-resolution applications. In contrast to client-server applications,
Web-based applications can be more rapidly and cost-effectively deployed to the
extended enterprise over the Internet or through corporate intranets and
extranets. This enables remote employees and business partners to leverage and
add to pre-existing organizational knowledge and thereby increase an
organization's effectiveness in resolving customer issues.
 
  We believe that with customer support playing a critical role in overall
customer-satisfaction a significant opportunity exists for software that:
 
  . enhances problem resolution through associative problem-solving
    technology
 
  . leverages the Internet and corporate intranets and extranets to capture
    and share organizational knowledge with customers, business partners and
    remote employees
 
  . provides scalability to meet the demands of the extended enterprise and
    Web-based customer self-service
 
  . integrates with existing information technology infrastructure
 
  Furthermore, we think that successful problem-resolution software will give
employees outside of the customer support department access to useful
information gained in the customer-support process. For example, employees in
other functional areas, such as product development, field service, and sales
and marketing, can use this information to identify problems with existing
products, target areas for new product development and understand changes in
customer needs and preferences.

Strategy
 
  Our objective is to establish and maintain a leadership position in providing
Web-based problem-resolution software applications for the extended enterprise
and its end-user customers. Our strategy to achieve this objective is to:
 
Leverage the Internet          We intend to continue to leverage the Internet
                               to enable our users to capture, manage and
                               share knowledge with their extended enterprise
                               and customers. We believe that businesses will
                               increasingly adopt the Web as the means of
                               providing fast and efficient customer support
                               for the extended enterprise.
 
Enhance our product suite      We plan to enhance the capabilities of our
                               SolutionSeries product family by developing,
                               acquiring and licensing additional products and
                               technologies. We intend to focus on
                               applications and technologies that further
                               enable Web-based customer self-service.
 
Target additional vertical     Initially, we have focused our sales and
markets                        marketing efforts on serving the customer-
                               support and problem-resolution needs of
                               technology-based industries, such as software,
                               hardware and telecommunications. We intend to
                               broaden the reach of our problem-resolution
                               products to customer-service and support
                               organizations in other industries with
                               characteristics similar to technology-based
                               industries. We believe that the critical market
                               characteristics indicating a need for our
                               products include:
 
                                   . a dynamic, rapidly changing business
                                     environment
 
                                   . complex products or services
 
                                   . competitive differentiation based on
                                     service and support
 
                               We currently plan to pursue the financial-
                               services, consumer electronics and
                               pharmaceutical industries.

                               We currently have strategic marketing
                               partnerships with several call-tracking and
                               customer-relationship-management software
                               vendors. We intend to strengthen and expand our
                               current relationships and build new ones with
                               leading systems consultants and integrators. We
                               believe that strategic relationships will
                               provide us with distribution opportunities, as
                               well as leverage our implementation resources.
                               Concurrently, we intend to expand our indirect
                               distribution channels to complement our direct
                               sales force.
 
Extend our solutions to
other functional areas
                               Our products currently provide information and
                               reports that are used in functional areas other
                               than customer support. We intend to continue to
                               enhance the features of our solutions to
                               provide benefits to functional business areas
                               in which the product feedback and customer
                               knowledge created in customer support is
                               valuable and actionable, such as product
                               development and sales and marketing.
 
Products
 
  The SolutionSeries product family consists of the SolutionBuilder
application, which we first released in April 1995, and our more recently
introduced Web-based applications, SolutionExplorer and SolutionPublisher. We
generally license our SolutionSeries applications based on the number of users
and servers. In 1998, the typical order sizes for our products ranged from
$50,000 to $500,000, with some over $1 million. Our users generally license the
full suite of SolutionSeries products.
 
  Our SolutionSeries products enable businesses to capture problem-resolution
information, solve customer problems, reuse solutions and share problem-
resolution knowledge throughout the extended enterprise.
 
Capture problem-resolution
information
                               Our SolutionSeries products enable users to
                               efficiently capture relevant information about
                               customer problems as the information becomes
                               available. Typically, a customer-support
                               analyst will capture facts and the symptoms of
                               the customer's problem using our
                               SolutionBuilder product while on the phone with
                               the customer. Field personnel and business
                               partners that provide customer support can also
                               capture problem-resolution information through
                               our Web-based applications. Because our system
                               captures problem-resolution information in the
                               workflow, there is no need to re-enter
                               information after solving the problem. Our
                               products' features help to reduce information-
                               input and call-processing times and facilitate
                               ease of use. Our SolutionSeries software:

                               problems or, if no solution exists, creates a
                               new solution to solve the problem. Our
                               SolutionSeries software:
 
                                   . Combines the natural language information

                                     problem
 
Reuse solutions                Our software is designed to enable a customer-
                               support organization to immediately reuse
                               solutions created in the ordinary workflow of
                               problem resolution. This process helps the
                               organization to improve first-call resolution
                               rates, reduce overall problem-resolution times
                               and avoid the cost and delay of off-line

  Our other SolutionSeries products include:
 
  SolutionSeries WebPack. We introduced our SolutionSeries WebPack product in
March 1999. SolutionSeries WebPack bundles SolutionExplorer and
SolutionPublisher with implementation services to enable new users of our
products to provide Web-based customer-self-service support solutions with an
accelerated deployment cycle, which we believe may be as little as five days.
 
  SolutionSeries Server. Our SolutionSeries Server product provides search
functionality, manages the problem-solution database interactions and controls
system administration. Our SolutionSeries Server includes our SolutionAdmin,
SolutionReports and SolutionX data-transfer utility modules, which provide
user-authority management, security services, report generation and data
exchange.

  Our typical license agreement provides for a perpetual, nontransferable
license to use our software by the licensee.
 
  Product Architecture
 
  Our products use an n-tiered architecture to meet the problem-resolution
needs of today's fast-paced and dynamic enterprises. We use industry-standard
platforms, components and communications interfaces to provide problem-
resolution software that is designed to be reliable, maintainable and scalable,
and provide high performance on an around-the-clock basis. Our flexible
architecture adapts to a range of needs, from a single desktop to enterprise
systems that support thousands of users.
 
  Our SolutionServer software runs on either Windows NT or Sun Solaris systems
in single- or multi-processor configurations. Our client software runs in a
fully customizable interface on both Web-based applications, using Microsoft or
Netscape browsers, and tailorable desktop applications for the professional
user.
 
  The core tier of our applications is the database server. We currently use
the Versant object-oriented database and plan to release implementations using
Microsoft SQL Server 7.0 and Oracle 8 and 8i databases. Our next tier is the
application search server that contains the search logic and knowledge domain
model. Our application server tier has multiple interfaces to either the
performance tuned SolutionBuilder communications interface or to the Internet
server application logic and session management. Our Internet server uses a
communications protocol that enables it to interface seamlessly with most
Internet clients, including Microsoft and Netscape clients.
 
Customer Support and Professional Services
 
  We believe that high-quality customer support and professional services are
requirements for continued growth and increased sales of our products. We have
made significant investments to increase the size of our support and services
organization in the past and plan to continue to do so in the future. As of
March 31, 1999, our customer support and professional services organization
consisted of 32 employees.
 
  Consulting. Our consulting teams work closely with our customers prior to
product implementation to review a customer's business objectives and
information technology infrastructure
 
                                       38
<PAGE>
 
in order to assist the customer in determining Primus solutions that will best
suit the customer's needs. Thereafter, our consultants install, integrate and
implement our software in the user's customer-support environment.
 
  Training. We provide training classes in conjunction with our products,
including end-user training and advanced technical training regarding the
implementation and administration of our products. Classes are offered at
customer sites and at our Seattle office. We also provide training classes for
third-party partners, such as service providers and systems integrators.
 
  Customer Support. We typically provide technical support 12 hours a day, five
days a week in North America. We offer similar services in the United Kingdom
and Japan. On-call support for priority matters is also available 24 hours a
day, 7 days a week. We offer support via telephone, fax, email and Web-based
self-service.
 
Customers
 
  Our products solve issues and problems associated with complex products and
services. As a result, we have traditionally targeted:
 
  . enterprises in dynamic, technology-related industries that offer external
    customer support
 
  . outsourcers that provide customer-support services to technology-related
    businesses
 
  . organizations with significant information-technology infrastructure that
    provide internal support to their employees

  The following case studies, which are based solely on information supplied by
the respective companies and which we believe to be accurate in all material
respects, illustrate how selected SolutionSeries customers are benefiting from
our products:
 
  3Com Corporation
 
  3Com develops and delivers information access products and network systems to
more than 200 million customers worldwide. Its customer base includes large,
medium and small enterprises; carriers and network service providers; PC OEMs;
and consumers.
 
  3Com initially purchased SolutionSeries software in July 1997 for its call
center operation to enhance employee productivity and customer resolution
rates. In August 1998, 3Com acquired additional licenses for its call center
and SolutionPublisher licenses to enable the company to offer its customers
another avenue to obtain technical support via the Web.
 
                                       39
<PAGE>
 
  In October 1998, 3Com launched the 3Com Knowledgebase Web service, an
interactive trouble-shooting tool containing a vast repository of technical
solutions input by expert 3Com technical engineers around the world. This
service, which utilizes the SolutionSeries products, has more than 132,000
registered end-users worldwide and, as of February 1999, was adding
approximately 9,000 new end-users a week, with repeat usage growing at 40% per
month. 3Com believes that its Knowledgebase Web service is not only assisting
3Com customers in solving their network challenges more quickly and easily, but
it is also providing actionable feedback to 3Com design, manufacturing and
technical-support personnel to enhance product quality and support processes.
 
  QAD, Inc.
 
  QAD is a leading provider of enterprise and extended supply-chain management
software and services to multinational corporations. QAD acquired
SolutionSeries software to help it manage increasing product complexity, rising
employee training costs, and the need to ensure a high level of customer
satisfaction. QAD selected SolutionSeries software because of its ability to
capture knowledge in the workflow, provide fast and flexible search results,
integrate with its own MFG/PRO software and document management systems and
facilitate management oversight to improve call center productivity.
 
  Once it had implemented the SolutionSeries software, QAD experienced a
reduction in call resolution times of more than 58%, a decrease of
approximately 50% in the amount of time required to train new employees, and an
increase in customer satisfaction of approximately 8%. In addition, by using
the SolutionPublisher application, QAD was able to deflect approximately 10% of
its incoming calls to its Web site.
 
  Compaq Computer Corporation
 
  Compaq Services Operations Management, a customer-support outsourcing
division of Compaq Computer Corporation, is an industry leader in implementing
and supporting high performance computer systems.
 
  Compaq Services purchased SolutionSeries software to lower their service
delivery costs and to maintain a comprehensive knowledge base of their
customers' information systems issues and requirements. Compaq Services uses
the knowledge base to analyze causes of recurring problems and to identify new
services to help customers reduce their information systems costs.
 
  Over an eight-month period, customer support staff at Compaq Services who
used the SolutionSeries applications were able to close incident tickets an
average of five minutes (or 20%) faster than staff who did not use the
SolutionSeries applications. Similarly, call center support staff who used the
SolutionSeries applications were able to resolve 15% more incidents over the
eight-month period than their counterparts who did not use the SolutionSeries
applications. This represents a reduction in the number of incidents that would
have otherwise been escalated to more sophisticated and more costly support
staff.
 
  Novell Corporation
 
  Novell launched the era of computer networking and today, with products like
NetWare 5 and Novell Directory Services, continues to extend its leadership in
Internet solutions based on open standards. Novell's global channel,
consulting, developer, education and technical support programs are among the
most extensive in the network computing industry.
 
 
                                       40
<PAGE>
 
  Novell purchased SolutionSeries software to reduce support costs by capturing
and re-using the knowledge of its internal and extended support community.
Because Novell's partners provide a substantial portion of the call center
support available to Novell end users, Novell decided to use Primus's Web-based
applications to distribute product information among its partners and internal
engineers over the Internet.
 
  Novell recognized the opportunities of knowledge sharing within its customer
service model and acquired Primus's SolutionExplorer product to enable members
of its extensive Novell Certified Engineer network to share product knowledge
with Novell and with other members of the network.
 
Sales and Marketing
 
  We market and sell our products primarily through a direct sales force. We
have sales offices in Seattle, Atlanta, Boston, Dallas, Reston and San
Francisco and in the United Kingdom. The field sales force is complemented by
direct telesales based at our headquarters in Seattle, Washington. To date,
significantly all of our efforts have been targeted at customer-service and
support organizations in the information technology and telecommunications
industries, as well as internal helpdesk organizations for companies with large
information-technology departments. These efforts are directed at key
executives and personnel responsible for the organizations' customer service
and support strategies and operations. Technical sales support is provided by
sales engineers located in several of the field offices. We currently plan to
add a significant number of sales representatives and sales engineers in other
domestic and international locations.
 
  Our marketing department is focused on creating awareness of our products and
services and generating interest in our solution. We conduct comprehensive
marketing and branding programs, which may include direct mail, public
relations, Web-based lead generation, telemarketing lead generation,
advertising, trade shows, seminars, and ongoing customer communications
programs. Many of our marketing activities are done in collaboration with our
consulting and software partners. Our marketing department also coordinates our
participation in industry tradeshows and forums, secures speaking engagements
for our executives and establishes and maintains close relationships with
recognized industry analysts. As of March 31, 1999, our sales and marketing
staff consisted of 58 employees.
 
  Our products are marketed and distributed in Japan by Primus KK, a joint
venture owned by Trans Cosmos Inc. and Primus. Our distribution arrangements
provide Trans Cosmos with exclusive worldwide distribution rights to the Kanji
version of our SolutionBuilder product and Primus KK with exclusive
distribution rights in Japan, and nonexclusive distribution rights in Korea, to
the English and Japanese versions of our SolutionExplorer and SolutionPublisher
products. The rights regarding our SolutionBuilder product expire in September
2000. The other rights are renewable for one-year terms. The agreements are
terminable by either party upon breach.
 
Product Development
 
  We have been a leader in developing innovative problem-resolution approaches
and were one of the first companies to use associative problem-solving
technology in a customer-support context. Our product development is focused on
enhancing our users' ability to implement global, Web-centric customer contact
centers using our products. We believe that a technically skilled, highly
productive software development organization will continue to be a key
component of our success. As of March 31, 1999, our product development team
consists of 38 full-time employees.
 
 
                                       41
<PAGE>
 
  Our current development efforts include enhancing our software development
kits and opening our application program interfaces to enable additional
development work by third-party developers and clients on software that
integrates with our products and extends their reach in problem resolution in
enterprise environments. In addition, we are broadening the databases on which
our SolutionServer product is implemented to include Microsoft's SQL Server 7.0
and the Oracle 8 and 8i database.
 
Competition
 
  The market for our products is new and rapidly evolving, and is expected to
become increasingly competitive as current competitors expand their product
offerings and new companies enter the market. Our primary source of direct
competition comes from other problem-resolution software vendors, e-commerce
customer-management software vendors and our potential customers' internal
information technology departments, which choose to rely upon their own
proprietary problem resolution systems or develop new proprietary systems.
Competitors providing problem-resolution systems include companies such as
Advantagekbs, Inference, Molloy, ServiceSoft and ServiceWare. In addition,
companies providing e-commerce customer-management solutions that may compete
with us include Broadvision, Silknet and Smart Technologies.
 
  The principal competitive factors in our industry include:
 
  . vendor and product reputation       . the availability of products on
                                          the Internet and multiple
                                          operating platforms

 
  . customer referenceability           . product ease-of-use
 
 
  . measurable economic return          . the quality of customer support
                                          services, documentation and
                                          training


  . product quality, performance and    . the quality and effectiveness of
    price                                 application deployment services
                                          
  
  . product functionality and           . the effectiveness of sales and
    features                              marketing efforts
                                          
 
  . product scalability
 
                                         
  . product integration with other        
    enterprise applications
 
 
  As the market for problem-resolution software matures, it is possible that
new and larger companies will enter the market, existing competitors will form
alliances, or current and potential competitors could acquire, be acquired by
or establish cooperative relationships with third parties. The resulting
organizations could have greater technical, marketing and other resources,
improve their products to address the needs of our existing and potential
users, thereby increasing their market share. Increased competition could
result in pricing pressures, reduced margins or failure of our products to
achieve or maintain market acceptance.
 
  Although we believe that our products and services currently compete
favorably with respect to such factors, we can't provide any assurance that we
can maintain our competitive position against current and potential
competitors, especially those with significantly greater financial, marketing,
service, support, technical and other resources.
 
Proprietary Information
 
  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
 
                                       42
<PAGE>
 
such as those contained in license agreements with consultants, vendors and
customers. 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. We are a party to a value added reseller
license agreement with Versant. Under the terms of the agreement, Versant
granted us a license to use Versant's database as part of our SolutionSeries
products. Versant also agreed to provide us with support and maintenance
services. We pay Versant a royalty on licenses of our products with the Versant
database. We can terminate the agreement on 120 days' prior written notice to
Versant. Versant can terminate the agreement on two years' prior written notice
to us. Either party may terminate following a material breach by the other, if
the breach has not been cured within 120 days of notice of breach.
 
Employees
 
  As of March 31, 1999, we had 147 employees, including 17 U.K.-based
employees. These included 58 in sales and marketing, 32 in client services and
support, 38 in product development and 19 in general and administration. None
of our employees is represented by a labor union. We have not experienced any
work stoppages, and we believe our relationship with our employees is good. In
addition, we regularly supplement our workforce with consultants.
 
  Competition for qualified personnel in our industry is intense. We believe
that our future success will depend in part on our continued ability to hire,
assimilate and retain qualified personnel.
 
Facilities
 
  Our principal administrative, engineering, manufacturing, marketing and sales
facilities total approximately 28,346 square feet in an office tower in
Seattle, Washington. Our principal lease expires on October 30, 2000. We also
lease other domestic sales and services offices in offices in Atlanta, Boston,
Dallas, Reston, and San Francisco. We maintain international offices in the
United Kingdom. We believe that our existing facilities are adequate to meet
current requirements and that additional or substitute space will be available
as needed to accommodate any expansion of operations.
 
Legal Proceedings
 
  Primus is not party to any material legal proceedings.

  Our bylaws provide for the division of our board of directors into three
classes as nearly equal in size as possible with staggered three-year terms.
The classification of our board could make it more difficult for a third party
to acquire, or could discourage a third party from acquiring, control of us.
 
Committees of the Board of Directors
 
  Our compensation committee currently consists of Messrs. Audino, Harman and
Matsumoto. The compensation committee:
 
  . reviews and approves the compensation and benefits for our executive
    officers
  . makes recommendations to the board of directors regarding such matters
 
  Our audit committee currently consists of Messrs. Haque and Harman. The audit
committee:
 
  . makes recommendations to the board of directors regarding the selection
    of independent auditors
  . reviews the results and scope of the audit and other services provided by
    our independent auditors
 
                                       45
<PAGE>
 
  . reviews and evaluates our audit and control functions
 
Director Compensation
 
  Our board of directors adopted our 1999 stock incentive compensation plan in
April 1999. A total of 1,166,667 shares of our common stock are currently
available for issuance under this plan. We expect our shareholders to approve
this plan in May 1999. Members of our board of directors are eligible to
participate in the 1999 plan.
 
Director and Officer Indemnification and Liability
 
  Our articles of incorporation limit the liability of directors to the fullest
extent permitted by the Washington Business Corporation Act as it currently
exists or as it may be amended in the future. Consequently, subject to the
Washington Business Corporation Act, no director shall be personally liable to
us or our shareholders for monetary damages resulting from his or her conduct
as one of our directors, except liability for:
 
  . acts or omissions involving intentional misconduct or knowing violations
    of law
  . unlawful distributions
  . transactions from which the director personally receives a benefit in
    money, property or services to which the director is not legally entitled
 
  Our articles of incorporation also provide that we will indemnify any
individual made a party to a proceeding because that individual is or was a
director of Primus and will advance or reimburse reasonable expenses incurred
by the individual in advance of the final disposition of the proceeding to the
full extent permitted by applicable law. Any repeal of or modification to our
articles of incorporation may not adversely affect any right of a director of
Primus who is or was a director at the time of such repeal or modification. To
the extent the provisions of our articles of incorporation provide for
indemnification of directors for liabilities arising under the Securities Act
of 1933, those provisions are, in the opinion of the Securities and Exchange
Commission, against public policy as expressed in the Securities Act and they
are therefore unenforceable.
 
  Our bylaws provide that we will indemnify our directors and officers and may
indemnify our employees and agents to the full extent permitted by law. In
addition, 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 Primus.
 
  We believe that the limitation of liability provision in our articles of
incorporation, the indemnification provisions in our bylaws and the liability
insurance policy will facilitate our ability to continue to attract and retain
qualified individuals to serve as our directors and officers.
 
Compensation Committee Interlocks and Insider Participation
 
  During the year ended December 31, 1998, Messrs. Brochu, Audino, Haque and
Harman served on the compensation committee of our board of directors, as did
Kenneth L. Block, a former director of Primus. No member of our board of
directors or of its compensation committee serves as a member of the board of
directors or compensation committee of any entity that has one or more
executive officers serving as members of our board of directors or its
compensation committee.
 
  Mr. Haque is a partner at Norwest Venture Capital Management, the general
partner of Norwest Equity Partners V, L.L.P. Between February 12, 1996 and July
22, 1998, Norwest Equity Partners

granted the Oak funds warrants for 26,499 shares of Series D preferred stock at
an aggregate exercise price of $66,000. The bridge loan converted into Series D
preferred stock in July 1998. The shares of preferred stock and warrants held
by affiliates of Mr. Harman will convert immediately prior to closing this
offering into 1,576,773 shares of common stock.
 
  In March 1999, Messrs. Brochu, Audino and Block purchased 1,000, 5,556 and
50,713 shares, respectively, of our common stock at a price per share of $9.00.
 
  Norwest Equity Partners and the Oak funds are parties to a registration
rights agreement with us. Pursuant to the terms of that agreement, the holders
of our preferred stock have certain registration rights that obligate us, under
certain circumstances, to effect a registration under the Securities Act of
shares of common stock. See "Description of Capital Stock--Registration
Rights."

Change of Control Agreements
 
  Primus has entered into an agreement with each of Michael A. Brochu, Kim M.
Nelson, Edward L. Walter, Elizabeth J. Huebner and Patricia L. Cox, that
provides for certain compensation arrangements upon and following a change of
control of the company. The agreements expire one year following a change of
control. A change of control occurs under the agreements when:
 
  . Primus completes a merger, consolidation or share exchange after which
    its prior shareholders own less than a majority of the surviving
    corporation
 
                                       49
<PAGE>
 
  .Primus sells substantially all of its assets not in the ordinary course of
  business
 
  .one person or entity acquires a majority of Primus's outstanding shares
 
  Immediately upon a change of control, 50% of the unvested options of each
executive become exercisable. Our 1995 and 1999 stock incentive compensation
plans also provide for vesting of all unvested options in certain circumstances
involving a merger, sale or liquidation of Primus.
 
  If one of our executives is terminated by us without cause or terminates his
or her employment due to a substantial change in his or her position or
responsibilities during the year following a change of control, then he or she
will be entitled to his or her accrued annual base salary through the date of
termination plus severance pay equal to one-half of annual base salary.
Further, all of his or her outstanding options will become immediately
exercisable.
 
Separation Agreement
 
  On November 6, 1998, we entered into a separation agreement with Mr. Sperry
in connection with his resignation as one of our officers and a member of our
board of directors. Under this agreement, we paid Mr. Sperry a lump sum
separation payment of $75,000.
 
Employment Arrangement
 
  In connection with hiring Ms. Huebner, we agreed to grant her, during the
first three years of her employment, options to purchase 200,000 shares of
common stock at an exercise price equal to the fair market value on the date of
grant. As of March 31, 1999 we had granted all but 56,668 options.
 
Employee Benefit Plans
 
  1999 Stock Incentive Compensation Plan
 
  Our board of directors has adopted our 1999 option plan, subject to
shareholder approval. The purpose of our 1999 option plan is to enhance long-
term shareholder value by offering opportunities to selected persons to
participate in our growth and success, and to encourage them to remain in the
service of Primus and its subsidiaries and to acquire and maintain ownership in
our company. Upon effectiveness of this offering, the 1999 option plan will
replace our current stock option plans for purposes of all future stock
incentive awards. The 1999 option plan provides for awards of stock options,
shares of common stock or units denominated in common stock, all of which may
be subject to restrictions. The board has reserved a total of 1,166,667 shares
of common stock under the plan, plus an automatic annual increase, to be added
on the first day of our fiscal year beginning in 2001, equal to the lesser of
666,667 shares and 5% of the average common shares outstanding as used to
calculate fully diluted earnings per share as reported in our annual report to
shareholders for the preceding year. Shares formerly available for issuance
under our 1995 option plan will become available under the 1999 option plan, as
will shares that become available when options granted under the old plans
expire or are otherwise cancelled without exercise.
 
  Stock Option Grants. The board of directors or a committee appointed by the
board will serve as the plan administrator of the 1999 option plan. The plan
administrator will have the authority to select individuals to receive options
under the 1999 option 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
 
                                       50
<PAGE>
 
grant), the vesting provisions and the option term. For purposes of the 1999
option 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 the plan administrator decides otherwise, and to the extent required for
incentive stock options by the Internal Revenue Code of 1986, as amended, an
option granted under the 1999 option plan will expire 10 years from the date of
grant.
 
  Stock Awards. The plan administrator is authorized under the 1999 option plan
to award shares of common stock or awards denominated in units of common stock
on such terms and conditions and subject to restrictions established by the
plan administrator in its sole discretion. The terms, conditions and
restrictions may be based, without limitation, on the manner in which shares
subject to stock awards held while restricted and the circumstances under which
a holder's service with us is terminated. Holders of restricted stock are
shareholders of Primus and have, subject to certain restrictions, all the
rights of shareholders with respect to their shares.
 
  Adjustments. The plan administrator will make proportional adjustments to the
number of shares issuable under the 1999 option 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 Primus, each outstanding option will be assumed or
replaced with a comparable award by Primus' successor corporation or parent
thereof. If the successor will not assume or replace the options, they will
automatically accelerate and become 100% vested and exercisable immediately
before the corporate transaction. To the extent that options accelerate due to
a corporate transaction, the restrictions or restricted stock awards also will
lapse.
 
  1999 Employee Stock Purchase Plan
 
  Our board of directors has adopted our 1999 employee stock purchase plan,
subject to shareholder approval. We will implement the 1999 stock purchase plan
upon the effectiveness of this offering to encourage employees to remain
employed by Primus or its subsidiaries. We intend for this plan to qualify
under Section 423 of the Internal Revenue Code.
 
  This plan permits eligible employees of Primus and its subsidiaries to
purchase common stock through payroll deductions of up to 10% of their
compensation. Under this plan, 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. Further, no employee may purchase more than 500 shares in any six-month
purchase period.
 
  We will implement the stock purchase plan with twenty-four-month offering
periods each of which will consist of four six-month purchase periods, except
that the first offering period will begin on the effectiveness of this offering
and end on December 31, 1999. Subsequent offering periods will begin on each
January 1 and July 1. The price of the common stock purchased under this plan
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 a purchase
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 the last day of each purchase period.
Under certain circumstances specified in the plan, the purchase price may be
adjusted during an offering period to avoid our incurring adverse accounting
charges. This plan terminates ten years after the date of adoption by our board
of directors, but the board may terminate it at any earlier time. We have not
yet issued any shares of common stock under this plan.
 
                                       51
<PAGE>
 
  Employees generally will be eligible to participate in the plan if they are
customarily employed by Primus for more than 20 hours per week and more than
five months in a calendar year, and are not (and would not become as a result
of being granted an option under the plan) 5% shareholders of Primus or its
subsidiaries.
 
  We authorized the issuance under this plan of a total of 600,000 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 200,000 shares and
1.7% of the average common shares outstanding as used to calculate fully
diluted earnings per share as reported in Primus' annual report to shareholders
for the preceding year, or a lesser amount determined by our board of
directors. Any shares from increases in previous years that are not actually
issued will be added to the aggregate number of shares available for issuance
in future periods.
 
  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 stock purchase plan will 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 transaction. Similarly, in the event of a proposed liquidation or
dissolution of Primus, 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.
 
  1995 Stock Incentive Compensation Plan
 
  Our board of directors and shareholders approved a stock incentive
compensation plan in 1995. As of March 31, 1999, there were 2,696,522 shares of
our common stock remaining available for issuance under this plan. In April
1999, we increased the shares reserved under the 1995 plan to 3,333,333. The
1995 plan provides for grants of incentive stock options, non-qualified stock
options, stock awards and stock appreciation rights. We will not grant further
options under our 1995 plan after effectiveness of this offering. As of March
31, 1999, options to purchase 2,671,881 shares of our common stock were
outstanding under the 1995 plan and 24,641 shares remained available for grant.
 
  Non-Employee Director Stock Option Plan
 
  Our board of directors and shareholders approved a non-employee director plan
in 1994. Our board discontinued further grants under our 1994 plan upon
adoption of our 1995 plan. As of March 31, 1999, options to purchase 8,332
shares of our common stock were outstanding under the 1994 plan.
 
  Employee Stock Option and Restricted Stock Award Plan
 
  Our board of directors and shareholders approved an employee stock option and
restricted stock award plan in 1993. Our board discontinued further grants
under the 1993 plan upon adoption of our 1995 plan. As of March 31, 1999,
options to purchase 235,214 shares of our common stock were outstanding under
our 1993 plan.

                              CERTAIN TRANSACTIONS
 
  In November 1995 we entered into a joint venture agreement with Trans Cosmos,
to establish Primus KK, a Japanese company. We hold a 14.3% interest in Primus
KK and have one of the six board seats.
 
  In November 1995, we issued 60,606 shares of common stock to Yuriko
Matsumoto, the wife of Mr. Matsumoto, at a per share price of $1.65. In
September 1996, Trans Cosmos purchased 813,008 shares of our Series A preferred
stock for $1.0 million. Mr. Matsumoto is the president and chief executive
officer of EnCompass Group, Inc., a wholly owned subsidiary of Trans Cosmos. In
July 1998, EnCompass Group purchased 108,204 shares of our Series D preferred
stock for $271,000 and Trans Cosmos purchased 600,000 shares of our Series D
preferred stock for $1.5 million. In September 1996 and March 1997, Trans
Cosmos USA, an affiliate of Trans Cosmos, bought 500,000 shares of our Series B
preferred stock and 1,000,000 shares of our Series C preferred stock,
respectively, for an aggregate price of $3.0 million. In connection with a
bridge loan financing in June 1998, we granted EnCompass Group warrants for
6,000 shares of Series D preferred stock at an aggregate exercise price of
$15,000. The bridge loan converted into Series D preferred stock in July 1998.
The shares of preferred stock and warrants held by affiliates of Mr. Matsumoto
will convert immediately prior to closing this offering into 1,076,818 shares
of common stock.
 
  In September 1997, we entered into an exclusive, worldwide distribution
agreement with Trans Cosmos for Kanji versions of our SolutionBuilder product.
Trans Cosmos bought $2.0 million of SolutionBuilder licenses and related
upgrade rights. Trans Cosmos pays us a portion of its technical support income
related to our SolutionBuilder product. Trans Cosmos's distribution rights
terminate on the earlier of September 26, 2000 or upon Trans Cosmos's sale of
all of its SolutionBuilder licenses.
 
  In September 1997, we granted Primus KK a first right of refusal with respect
to distribution of Asian-language versions of our products. In March 1999, we
entered into a one-year software marketing and distribution agreement with
Primus KK. The agreement provides Primus KK with exclusive distribution rights
in Japan, and nonexclusive distribution rights in Korea, to English and
Japanese versions of our SolutionExplorer and SolutionPublisher products.
Primus KK pays us royalty on license and maintenance fees for those products.
Unless either party terminates, the agreement automatically renews for
additional one-year periods. The agreement has customary termination provisions
for breach and for failure by Primus KK to meet certain revenue and staffing
goals.
 
  In February 1998, we entered into a service agreement with EnCompass
Globalization, Inc., an affiliate of Trans Cosmos, under which EnCompass
Globalization agreed to provide us with localization, translation and testing
services for Japanese versions of our SolutionSeries products. EnCompass
Globalization provides its services on a time and materials basis. The term of
the agreement is not fixed, but specific projects are described in mutually
agreed statements of work that establish time frames in which the projects are
to be completed.
 
  In April 1999, we agreed to issue an aggregate of 18,333 shares of common
stock to Primus KK for issuance to its employees as compensation for their past

                          DESCRIPTION OF CAPITAL STOCK
 
  We are authorized to issue up to 50,000,000 shares of common stock, $.025 par
value per share, and 15,000,000 shares of preferred stock, $.001 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 articles of incorporation, which are included as an exhibit to the
Registration Statement, of which this prospectus is a part.
 
Common Stock
 
  As of March 31, 1999, assuming conversion of all outstanding shares of
preferred stock and our one-for-three reverse stock split, there were 9,435,407
shares of common stock outstanding held of record by 187 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. If Primus 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, each outstanding share of Series A
convertible preferred stock will convert into 0.41 shares of common stock. Each
outstanding share of Series B preferred stock, Series C preferred stock and
Series D preferred stock will convert into 0.333 shares of Common Stock.
Thereafter, pursuant to our articles of incorporation, the board of directors
will have the authority, without further action by the shareholders, to issue
up to 15,000,000 shares of preferred stock in one or more series. The board
also has the authority to fix the designations, powers, preferences, privileges
and relative, participating, optional or special rights and the qualifications,
limitations or restrictions of any preferred stock issues, 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 Primus 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 5,707,555 shares of common stock will be
entitled to certain rights with respect to the registration of such shares
under the Securities Act, pursuant to a
 
                                       56
<PAGE>
 
registration rights agreement. Under the terms of the registration 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 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 February 2000 and six months after the closing of this offering.
 
Antitakeover Effects of Certain Provisions of Articles of Incorporation, Bylaws
and Washington Law
 
  As noted above, our board of directors, without shareholder approval, has the
authority under our articles of incorporation to issue preferred stock with
rights superior to the rights of the holders of common stock. As a result,
preferred stock could be issued quickly and easily, could adversely affect the
rights of holders of common stock and could be issued with terms calculated to
delay or prevent a change in control of Primus or make removal of management
more difficult.
 
  Election and Removal of Directors. Effective with the first annual meeting of
shareholders following this offering, our articles of incorporation 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 Primus
and may maintain the incumbency of the board of directors.
 
  Approval for Certain Business Combinations. Our articles of incorporation
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 articles of incorporation and 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 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
Washington Business Corporation Act prohibits a
 
                                       57
<PAGE>
 
"target corporation," with certain exceptions, from engaging in certain
significant business transactions with an "acquiring person," which is defined
as a person or group of persons that beneficially owns 10% or more of the
voting securities of the target corporation, for a period of five years after
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
  . 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 Primus.
 
Transfer Agent and Registrar
 
  The transfer agent and registrar for the common stock is ChaseMellon
Shareholder Services, L.L.C.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has been no public market for the common stock.
We cannot provide any assurance 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
(         shares if the underwriters' over-allotment option is exercised in
full). 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 Primus, as that term is defined in Rule 144 under the
Securities Act.
 
  The remaining 9,535,929 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 Primus, who collectively hold an
aggregate of       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,       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       restricted shares will be eligible for
immediate sale (of which       shares will be subject to certain volume, manner
of sale and other limitations under Rule 144). The remaining       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. Under Rule
144, beginning 90 days after the date of this prospectus, a person who has
beneficially owned restricted shares for at least one year would be entitled to
sell in any three-month period up to the greater of
 
  . 1% of the then-outstanding shares of common stock (approximately
    shares immediately after this offering)
  . 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.
 
 
                                       59
<PAGE>
 
  Sales under Rule 144 are also subject to certain manner of sale and notice
requirements and to the availability of current public information about
Primus. Under Rule 144(k), a person who has not been an affiliate of Primus
during the preceding 90 days and who has beneficially owned the restricted
shares for at least two years is entitled to sell them without complying with
the manner of sale, public information, volume limitation or notice provisions
of Rule 144.
 
  We intend to file, after the effective date of this offering, a registration
statement on Form S-8 to register up to approximately 4,602,094 shares of
common stock reserved for issuance under our 1993 stock plan, our 1994 stock
plan, our 1995 stock plan, our 1999 stock plan and our 1999 employee stock
purchase plan. 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 5,707,555 shares of
outstanding common stock will, under certain circumstances, have rights to
require us to register their shares for future sale.

  The representatives have advised us that the underwriters propose to offer
the shares of common stock to the public at the public offering price set forth
on the cover page of this prospectus and to certain dealers at such price less
a concession of not in excess of $      per share, of which $      may be
reallowed to other dealers. After the initial public offering, the public
offering price, concession and reallowance to dealers may be reduced by the
representatives. No such reduction shall change the amount of proceeds to be
received by us as set forth on the cover page of this prospectus. The common
stock is offered by the underwriters as stated herein, subject to receipt and
acceptance by them and subject to their right to reject any order in whole or
in part.
 
  The underwriters do not intend to confirm sales to any accounts over which
they exercise discretionary authority.
 
  Over-allotment Option. We have granted to the underwriters an option,
exercisable during the 30-day period after the date of this prospectus, to
purchase up to           additional shares of common stock at the same price
per share as we will receive for the           shares that the underwriters
have agreed to purchase. To the extent that the underwriters exercise this
option, each of the underwriters will have a firm commitment, subject to
certain conditions, to purchase approximately the same percentage of such
additional shares that the number of shares of common stock to be purchased by
it shown in the above table represents as a percentage of the           shares
offered hereby. If purchased, such additional shares will be sold by the
underwriters on the same terms as those on which the           shares are being
sold. We will be obligated, pursuant to the option, to sell shares to the
extent the option is exercised. The underwriters may exercise such option only
to cover over-allotments made in connection with the sale of the shares of
common stock offered hereby. If such option is exercised in full, the total
public offering price of the      shares we sell to the underwriters,
underwriting discounts and commissions on such shares and total proceeds to us
from the sale of such shares will be $         , $          and $         ,
respectively.
 
                                       61

  Indemnity. The underwriting agreement contains covenants of indemnity among
the underwriters and us against certain civil liabilities, including
liabilities under the Securities Act and liabilities arising from breaches of
representation and warranties contained in the underwriting agreement.
 
  Lock-up Agreements. Under the terms of lock-up agreements, each of our
officers and directors and certain of our shareholders have agreed with the
representatives, for a period of 180 days after the date of this prospectus,
subject to certain exceptions, not to offer to sell, contract to sell, or
otherwise sell, dispose of, loan, pledge or grant any rights with respect to,
any shares of common stock, or any securities convertible into or exchangeable
for shares of common stock, now owned or hereafter acquired directly by such
holders or with respect to which they have the power of disposition, without
the prior written consent of BancBoston Robertson Stephens. However, BancBoston
Robertson Stephens may, in its sole discretion and at any time without notice,
release all or any portion of the securities subject to the lock-up agreements.
There are no agreements between the representatives and any of our shareholders
providing consent by the representatives to the sale of shares prior to the
expiration of the period 180 days after this prospectus.
 
  Future Sales. In addition, we have agreed that during the 180 days after the
date of this prospectus, we will not, subject to certain exceptions, without
the prior written consent of BancBoston Robertson Stephens:
 
  . Consent to the disposition of any shares held by shareholders prior to
    the expiration of the period of 180 days after the date of this
    prospectus; or
 
  . Issue, sell, contract to sell or otherwise dispose of any shares of
    common stock or any securities convertible into, exercisable for or
    exchangeable for shares of common stock, other than the sale of shares in
    this offering, the issuance of common stock upon the exercise of
    outstanding options or warrants or our issuance of options or shares
    under our 1999 stock incentive compensation plan and our 1999 employee
    stock purchase plan.
 
  Listing. We have applied for listing on the Nasdaq National Market under the
symbol "PKSI."
 
  No Prior Public Market. Prior to this offering, there has been no public
market for our common stock. Consequently, the initial public offering price
for the common stock offered hereby will be determined through negotiations
between us and the representatives. Among the factors to be considered in such
negotiations are prevailing market conditions, certain of our financial
information, market valuations of other companies that we and the
representatives believed to be comparable to us, estimates of our business

representatives have advised us that such transactions may be effected on the
Nasdaq National Market or otherwise and, if commenced, may be discontinued at
any time.

not so purchased will be offered by the underwriters to the general public on
the same basis as the other shares offered hereby.

               Report of Ernst & Young LLP, Independent Auditors
 
The Board of Directors and Shareholders
Primus Knowledge Solutions, Inc.
 
  We have audited the accompanying consolidated balance sheets of Primus
Knowledge Solutions, Inc. as of December 31, 1997 and 1998, and the related
consolidated statements of operations, shareholders' deficit, and cash flows
for each of the three years in the period ended December 31, 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 Primus
Knowledge Solutions, Inc. at December 31, 1997 and 1998, and the consolidated
results of its operations and its cash flows for each of the three years in
the period ended December 31, 1998, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
  (Information as of and for the three months ended March 31, 1998 and 1999 is
                                   unaudited)
 
1. SIGNIFICANT ACCOUNTING POLICIES AND LIQUIDITY
 
Description of Business
 
  Primus Knowledge Solutions, Inc. (Primus or the Company) is a leading
provider of Web-based problem-resolution software for customer support and
self-service, which enables businesses to capture problem-resolution
information, solve customer problems, reuse solutions stored in the knowledge
base and share captured knowledge throughout the extended enterprise.
 
  The Company's primary market is comprised largely of technology companies.
Sales are primarily generated through a domestic and European field sales
organization. Products sold domestically and internationally are developed by
the Company at its Seattle headquarters.
 
  The Company is subject to certain business risks that could affect future
operations and financial performance. These risks include changing computing
environments, rapid technological change, development of new products, limited
protection of proprietary technology, and competitive pricing.
 
Liquidity
 
  The Company continues to incur losses from operating results and had a
shareholders' deficit of $22.2 million at December 31, 1998. The Company had
shareholders' equity of approximately $910,000 at December 31, 1998 on a pro
forma basis, assuming conversion of preferred stock to common stock. As a
result of its significant research and development, customer support, and
selling and marketing efforts, the Company has required substantial working
capital to fund its operations. To date, the Company has financed its
operations principally through its equity offerings. Management believes that
under its current business plans, its current working capital, cash flows from
operating activities and funds available from borrowing arrangements are
sufficient to fund its operations and capital requirements through at least
December 31, 1999. Any substantial inability to achieve the current business
plan could have a material adverse impact on the Company's financial position,
liquidity, or results of operations and may require the Company to reduce
expenditures to enable it to continue operations through December 1999.
 
Principles of Consolidation
 
  The consolidated financial statements include the accounts of the Company and
its wholly owned foreign subsidiary, Primus UK. All significant intercompany
balances and transactions have been eliminated.
 
Interim Financial Information
 
  The financial information at March 31, 1999 and for the three months ended
March 31, 1999 and 1998 is unaudited, but includes all adjustments (consisting
only of normal recurring adjustments) that Primus considers necessary for a
fair presentation of the financial position at such date and the operating
results and cash flows for those periods. Operating results for the three
months ended March 31, 1999 are not necessarily indicative of the results that
may be expected for the entire year.
 
Investment in Primus KK
 
  In December 1995, Primus invested $50,000 for a 50% interest in Primus KK, a
Japanese distributor, with Trans Cosmos Inc., a Japanese company (TCI), a
significant shareholder of the

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
  (Information as of and for the three months ended March 31, 1998 and 1999 is
                                   unaudited)
 
1. Significant Accounting Policies and Liquidity--(continued)
 
Company. Primus accounted for its investment using the equity method and, wrote
down its investment to zero in March 1997 as a result of recognizing the
Company's portion of the investee's losses to date. In September 1997, Primus
and TCI renegotiated their agreement, reducing Primus' ownership to 14.3%. The
investment is accounted for using the cost method.
 
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.
 
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 later amended by Statement of Position 98-4 ("SOP 98-4").
The Company adopted SOP 97-2 effective January 1, 1998. The Company believes
its current revenue recognition policies and practices are consistent with SOP
97-2 and SOP 98-4. However, full implementation guidelines for these standards
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 timing of the Company's future
revenues and earnings. Additionally, the AICPA recently issued SOP 98-9, which
provides certain amendments to SOP 97-2, which is effective for transactions
entered into beginning January 1, 2000. This pronouncement is not expected to
materially impact the Company's revenue recognition practices.
 
  The Company generates revenues through two sources: (1) software license
revenues and (2) service revenues. Software license revenues are generated from
licensing the rights to use the Company's products directly to end-users and
indirectly through resellers. Service revenues are generated from sales of
maintenance services, consulting services, and training services performed for
customers that license the Company's products.
 
  Revenues from software license agreements are recognized over the software
implementation period (if sold with initial implementation services) or upon
delivery of software (if sold without implementation services) 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 when reported by the
reseller upon relicensing of the Company's product to end users. The Company's
agreements with its customers and resellers do not contain product return
rights.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
  (Information as of and for the three months ended March 31, 1998 and 1999 is
                                   unaudited)
 
1. Significant Accounting Policies and Liquidity--(continued)
 
 
  Revenues from maintenance 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-material basis under separate
service arrangements. Revenues from consulting and training services are
recognized as services are performed. 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 purchased with an
original maturity of three months or less to be cash equivalents. The Company's
cash equivalents consist of money market funds and commercial paper.
 
Securities Available-for-Sale
 
  Securities available-for-sale consist primarily of investment-grade corporate
obligations, all of which mature within 12 months from purchase.
 
  Investments classified as available-for-sale are stated at amortized cost,
which approximates fair market value, and mature within one year. Interest
earned on securities available-for-sale is included in interest income. The
cost of debt securities in this category is adjusted for amortization of
premiums and accretion of discounts to maturity. Such amortization and
accretion are included in interest income. Realized gains and losses and
declines in value judged to be other than temporary on securities available-
for-sale are also included in interest income. The cost of securities sold is
calculated using the specific identification method.
 
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 different geographic areas throughout North
America, Europe, and Japan. During 1996 and 1997, no single customer accounted
for 10% or more of total revenues. One customer's purchases represented 12% of
1998 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.
 
Property and Equipment
 
  Property and equipment is stated at cost, less accumulated depreciation.
Depreciation and amortization is provided on a straight-line basis over the
estimated useful lives of the assets (three to seven years) or over the lease
term if it is shorter for leasehold improvements.
 
Fair Value of Financial Instruments
 
  At December 31, 1998, the recorded amounts of cash and cash equivalents,
accounts receivable and payable, prepaid royalties, and accrued liabilities
reflected in the financial statements approximate fair value due to the short-
term nature of the instruments.

1. Significant Accounting Policies and Liquidity--(continued)
 
 
  The fair value of the Company's long-term debt and obligations under capital
leases approximates the carrying value of these obligations.
 
Development Costs
 
  Costs incurred in the research and development of new software products and
enhancements to existing software products are expensed as incurred until
technological feasibility has been established. The Company believes its
current process for developing software is essentially completed concurrently
with the establishment of technological feasibility; accordingly, software
costs incurred after the establishment of technological feasibility have not
been material and, therefore, have been expensed.
 
Federal Income Taxes
 
  The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes," which
utilizes the liability method of accounting for income taxes. A deferred tax
asset or liability is recorded for all temporary differences between financial
and tax reporting. Valuation allowances are established when necessary to
reduce deferred tax assets to amounts expected to be realized.
 
Foreign Currency Translation
 
  The functional currency of the Company's foreign subsidiary 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' deficit.
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.
 
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 8).

1. Significant Accounting Policies and Liquidity--(continued)
 
 
Supplemental Disclosure on Noncash Investing and Financial Information
 
  During 1998, the Company acquired 78,889 shares of common stock, that had
been issued for more than six months, valued at $473,332 in exchange for
amounts due in the exercise of 230,214 common stock options.
 
  During 1998, the Company acquired $81,400 of equipment through a capital
lease.
 
  During 1996, the Company issued 12,208 shares of common stock in a cashless
exercise of common stock options. Compensation expense of $9,797 was recorded
in connection with the net issuance.
 
Advertising
 
  Advertising costs are expensed as incurred. Advertising expense was $76,000,
$218,000, and $394,000 during the years ended December 31, 1996, 1997, and
1998, respectively.
 
Loss Per Share and Pro Forma Loss Per Share
 
  Basic and diluted net loss per share is computed by dividing loss available
to common shareholders by the average number of common shares outstanding for
the period. Other common stock equivalents, including stock options, warrants,
and convertible preferred stock, are excluded from the calculation because
their effect is antidilutive.
 
  Upon the completion of the Company's proposed initial public offering, all
preferred stock will either automatically convert into common stock or it is
assumed that the preferred stockholders will voluntarily convert into common
stock. Accordingly, pro forma basic and diluted loss per share is computed
using the weighted average number of shares of common stock outstanding and the
weighted average preferred stock outstanding as if such shares were converted
to common stock at the time of issuance.
 
Other Comprehensive Income
 
  In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive Income"
(SFAS 130), which establishes standards for reporting and display of
comprehensive income and its components in the financial statements. The
Company adopted SFAS 130 in 1998. The only item of other comprehensive income
(loss) which the Company currently reports is foreign currency translation
adjustments.
 
Business Segments
 
  In June 1997, the FASB issued SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information" (SFAS 131), which establishes standards for
reporting information about operating segments in annual financial statements.
As the Company operates only in one segment, the adoption of SFAS 131 did not
impact the Company's disclosures.

  The Tax Reform Act of 1986 limits the use of net operating loss and tax
credit carryforwards in certain situations where changes occur in the stock
ownership of a company. The Company may have experienced such ownership changes
as a result of the various stock offerings and the utilization of the
carryforwards could be limited.
 
  Due to the Company's history of net operating losses, the Company has
established a valuation allowance equal to its net deferred tax assets on the
basis that realization of such assets is not assured. The valuation allowance
increased $2,070,000, $2,197,000 and $3,677,000 during 1996, 1997, and 1998,
respectively.
 
7. Redeemable Convertible Preferred Stock
 
  In February 1996, Primus completed a private offering of 6,910,568 shares of
Series A redeemable and convertible preferred stock (Series A) for $7,920,000,
net of offering costs of $580,000. In March 1997, Primus completed a private
offering of 1,000,000 shares of Series C preferred stock (Series C) for
$1,969,000, net of offering costs of $31,000. In July 1998, Primus completed a
private offering of 4,900,000 shares of Series D redeemable and convertible
preferred stock (Series D) for $12,213,000, net of offering costs of $37,000.
 
  Holders of Series A, C, and D have preferential rights to dividends when and
if declared by the Board of Directors. The holders are entitled to the number
of votes equal to the number of shares of common stock into which the preferred
stock could be converted. In the event of liquidation, the holders of Series A,
C, and D have preferential right to liquidation payments of $1.23, $2.00, and
$2.50 per share, respectively, plus any accrued but unpaid dividends. The
preferred stock is convertible into common stock as provided by the Articles of
Incorporation (Articles) (all preferred stock is currently convertible into
0.333 shares of common stock, except Series A, which is convertible into .410
shares of common stock), at the option of the holder, or automatically upon the
vote or written consent of the holders of a majority of the shares of
applicable Series then outstanding, or upon the closing of an initial public
offering of the Company's common stock from which the net proceeds are at least
$10 million and at a price per share of at least $10.50, $15.00, and $30.00
with regard to Series A, C, and D, respectively.

Convertible Preferred Stock
 
  In September 1996, Primus completed a private offering of 500,000 shares of
Series B convertible preferred stock (Series B) for $981,000, net of offering
costs of $19,000. Holders of Series B have preferential rights to dividends
when and if declared by the Board of Directors. The holders are entitled to the

preferred stock could be converted. In the event of liquidation, the holders of
Series B have preferential rights to liquidation payments of $2.00 per share,
plus any accrued but unpaid dividends. The preferred stock is convertible into
common stock as provided by the Articles of Incorporation (Articles) (currently
convertible into 0.333 shares of common stock), at the option of the holder, or
automatically upon the vote or written consent of the holders of a majority of
the shares of applicable Series then outstanding, or upon the closing of an
initial public offering of the Company's common stock from which the net
proceeds are at least $10 million and at a price per share of at least $10.50.
In addition, the Company has granted rights of first offer to the Series B
holders and is precluded from carrying out certain actions without the approval
of the majority of the Series B holders voting as a group.

  The Company recognized $4,452, $1,969, and $706 during 1996, 1997, and 1998,
respectively, of consulting expense equal to the estimated fair value of
options granted to consultants.
 
  Pro forma information regarding net loss is required by SFAS 123 and has been
determined as if the Company had accounted for its employee stock options under
the fair market value method of SFAS 123. The fair value of these options was
estimated at the date of grant using a minimum value option pricing model using
the multiple-option approach with the following weighted-average assumptions:
risk-free interest rates range from 5.61% to 4.45% in 1998, 5.71% to 6.75% in
1997; and 6.09% to 6.46% in 1996; an expected life of the options of five
years, and a dividend yield rate of 0% for all years.
 
  For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period. The Company's
pro forma information follows:

  Under SFAS 123, compensation expense representing the fair value of the
option grant is recognized over the vesting period. The initial impact on pro
forma net loss may not be representative of compensation expense in future
years, when the effect of amortization of multiple awards would be reflected in
pro forma earnings.

14. Subsequent Events
 
Initial Public Offering
 
  In April 1999, 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. If the offering is
consummated under terms presently anticipated, each outstanding share of Series
A redeemable convertible preferred stock will convert into 0.410 shares of
common stock, and all other preferred stock will convert into 0.333 shares of
common stock. Unaudited pro forma shareholders' equity reflects the assumed
conversion of the preferred stock into common stock and the assumed conversion
of redeemable convertible preferred stock warrants into common stock warrants
as of March 31, 1999.
 
Employee Stock Purchase and Incentive Plans
 
  In April 1999, the Board increased the shares reserved under the 1995 Stock
Incentive Compensation Plan by 500,000 and adopted the 1999 Stock Incentive
Compensation Plan and the Employee Stock Purchase Plan, subject to shareholder
approval. A total of 1,166,667 shares of common is reserved under the Stock
Incentive Compensation Plan, plus annual increases as defined in the plan
document. The Employee Stock Purchase Plan authorizes the issuance of 600,000
shares of common stock, plus annual increases as defined by the plan document.
 
Reverse Stock Split and Capitalization Change
 
  In April 1999, the Board of Directors authorized a 1-for-3 reverse stock
split of the Company's common stock and, in connection with the stock split,
the Company adjusted the authorized shares in its capitalization subject to
shareholder approval. The related common stock and per-share data in the
accompanying financial statements has been retroactively stated to reflect the
reverse stock split.
 
Bank Financing
 
  In April 1999, the Company renewed its financing arrangement with the bank,
which provides a $5 million line of credit and a $1 million term loan. The line
of credit matures in April 2000, and bears interest at rates of Prime plus
0.75%. The term loan is available for advances for 1 year during which time
interest only is payable at prime plus 1% after which principal and interest
payments are due in equal monthly payments over 3 years beginning April 2000.
The arrangement is secured by all assets of the Company. The agreement includes
certain financial covenants including those requiring the Company to maintain
minimum levels of working capital, liquidity and minimum levels of
profitability. In connection with the arrangement the Company issued warrants
to purchase 23,333 shares of common stock at an exercise price of $10.50.

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 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
specifically provided in writing by the Underwriters for inclusion in this
Registration Statement.

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.

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 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.

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.

                       PRIMUS COMMUNICATIONS CORPORATION

                         REGISTRATION RIGHTS AGREEMENT

     This REGISTRATION RIGHTS AGREEMENT is entered into as of the 9th day of
February, 1996, by and among PRIMUS COMMUNICATIONS CORPORATION, a Washington
corporation (the "Company"), and the parties listed on Schedule A hereto (the
"Investors"), as at any time amended.

                                    RECITALS

     The Investors are purchasing, as of the date of this Agreement, shares of
the Company's Series A Convertible Preferred Stock (the "Series A Stock").

                                   AGREEMENT

     NOW, THEREFORE, for good and valuable consideration, the receipt of which
is hereby acknowledged, the parties hereto agree as follows:

l.  Definitions

     For purposes of this Agreement:

          (a) The term "register," "registered" and "registration" refer to a
registration effected by preparing and filing a registration statement or
similar document in compliance with the Securities Act of 1933, as amended (the
"Act"), and the declaration or ordering of effectiveness of such registration
statement or document;

          (b) The term "Registrable Securities" means (i) the Common Stock of
the Company issuable or issued upon conversion of the Series A Stock and (ii)
any Common Stock of the Company issued as (or issuable upon the conversion or
exercise of any warrant, right or other security which is issued as) a dividend
or other distribution with respect to, or in exchange for or in replacement of,
such Series A Stock or Common Stock, excluding in all cases, however, any
Registrable Securities sold by a person in a transaction in which its rights
under this Agreement are not assigned;

          (c) The number of shares of "Registrable Securities then outstanding"
shall be determined by the number of shares of Common Stock outstanding which
are, and the number of shares of Common Stock issuable pursuant to then
exercisable or convertible securities which are, Registrable Securities;

          (d) The term "Holder" means any person owning or having the right to
acquire Registrable Securities who is a party to this Agreement as of the date
hereof or who

- --------------------------------------------------------------------------------
REGISTRATION RIGHTS AGREEMENT                                            Page 1
<PAGE>
 
may be added as a party hereto pursuant to the terms of this Agreement, and any
assignee thereof in accordance with Section 12; and

          (e) The term "Form S-3" means such form under the Act as in effect on
the date hereof or any registration form under the Act subsequently adopted by
the Securities and Exchange Commission (the "SEC") that similarly permits
inclusion or incorporation of substantial information by reference to other
documents filed by the Company with the SEC.

2.  Request for Registration

          (a) If the Company shall receive, at any time after the earlier of (i)
February 9, 2000 or (ii) six months after the effective date of the first
registration statement for a public offering of securities of the Company to the
general public, a written request from the Holders of at least 30% of the
Registrable Securities then outstanding that the Company file a registration
statement (other than on Form S-3) under the Act covering the registration (x)
of at least 25% of the Registrable Securities originally issued to the Holders
with an aggregate offering price to the public of such Registrable Securities
reasonably expected to be not less than $20,000,000 or (y) of at least
$7,500,000 of Registrable Securities with an aggregate offering price to the
public of such Registrable Securities and all other securities included in such
registration reasonably expected to be not less than $15,000,000, then the
Company shall, within ten days of the receipt of such request, give written
notice of such request to all Holders and shall, subject to the limitations of
Section 2(b), use its best efforts to effect as soon as practicable the
registration under the Act of all Registrable Securities that the Holders
request to be registered in a written request to be given within 30 days of the
mailing of such notice by the Company.

          (b) The Holders initiating the registration request hereunder
("Initiating Holders") must distribute the Registrable Securities covered by
their request by means of a public offering underwritten by a reputable national
or regional underwriter.  The right of any Holder to include its Registrable
Securities in such registration shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their Registrable Securities through such
underwriting shall (together with the Company as provided in Section 4(e)) enter
into an underwriting agreement in customary form with the underwriter or
underwriters selected for such underwriting by a majority in interest of the
Initiating Holders.  Notwithstanding any other provision of this Section 2, if
the underwriter advises the Initiating Holders in writing that marketing factors
require a limitation of the number of shares to be underwritten, then the
Initiating Holders shall so advise all Holders of Registrable Securities which
would otherwise be underwritten pursuant hereto, and the number of shares of
Registrable Securities that may be included in the underwriting shall be
allocated among all Holders thereof, including the Initiating Holders, in
proportion (as nearly as practicable) to the amount of Registrable Securities of
the Company owned by each Holder.

<PAGE>
 
          (c) The Company is obligated to effect no more than two registrations
pursuant to this Section 2 or more than one such registration during any 12-
month period.

          (d) Notwithstanding the foregoing, if the Company shall furnish to the
Holders requesting a registration statement pursuant to this Section 2:  (i) a
certificate signed by the President of the Company stating that in the good
faith judgment of the Board of Directors of the Company it would be seriously
detrimental to the Company and its shareholders for such registration statement
to be filed and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer such filing
for up to two periods of not more than 90 days each after receipt of the request
of the Initiating Holders; provided, however, that the Company may not use this
right more than once (for a total of up to 180 days) in any 12-month period or
(ii) within 30 days of receiving a request for registration pursuant to this
Section 2, a certificate signed by the President of the Company stating that the
Company intends within 45 days of the date of such certificate to file a
registration statement for the initial public offering of securities of the
Company to the general public, the Company shall not be obligated to effect the
registration requested pursuant to this Section 2; provided, however, that the
Company shall promptly notify the Holders requesting a registration pursuant to
this Section 2 of any decision by the Company to abandon or indefinitely delay
such initial public offering.

3.  Company Registration

     If (but without any obligation to do so) the Company proposes to register
(including for this purpose a registration effected by the Company for
shareholders other than the Holders) any of its stock or other securities under
the Act in connection with the public offering of such securities solely for
cash (other than a registration relating solely to the sale of securities to
participants in a Company stock plan, or a registration on any form that does
not include substantially the same information as would be required to be
included in a registration statement covering the sale of the Registrable
Securities), the Company shall, at each such time, promptly give each Holder
written notice of such registration.  Upon the written request of each Holder
given within 20 days after mailing of such notice by the Company, the Company
shall, subject to the provisions of Section 8, cause to be registered under the
Act all of the Registrable Securities that each such Holder has requested to be
registered.

4.  Obligations of the Company

     Whenever required under this Agreement to effect the registration of any
Registrable Securities, the Company shall, as expeditiously as reasonably
possible:

          (a) Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the Holders
of a majority of the Registrable Securities registered thereunder, keep such
registration statement effective for up to 90 days.

<PAGE>
 
          (b) Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
Act with respect to the disposition of all securities covered by such
registration statement.

          (c) Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Act, and such other documents as they may reasonably request in order to
facilitate the disposition of all securities covered by such registration
statement.

          (d) Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided that the Company shall not be required in connection therewith or as a
condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions.

          (e) In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering.  Each Holder participating
in such underwriting shall also enter into and perform its obligations under
such an agreement.

          (f) Notify each Holder of Registrable Securities covered by such
registration statement, at any time when a prospectus relating thereto covered
by such registration statement is required to be delivered under the Act, of the
happening of any event as a result of which the prospectus included in such
registration statement, as then in effect, includes an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in the light of the
circumstances then existing.

          (g) At the request of any Holder requesting registration of
Registrable Securities pursuant to this Agreement, furnish on the date that such
Registrable Securities are delivered to the underwriters for sale in connection
with a registration pursuant to this Agreement (i) an opinion, dated such date,
of the counsel representing the Company for the purposes of such registration,
in form and substance as is customarily given to underwriters in an underwritten
public offering, addressed to the underwriters and (ii) a letter dated such
date, from the independent certified public accountants of the Company, in form
and substance as is customarily given by independent certified public
accountants to underwriters in an underwritten public offering, addressed to the
underwriters.

5.  Furnish Information

     It shall be a condition precedent to the obligations of the Company to take
any action pursuant to this Agreement that the selling Holders shall furnish to
the Company such information regarding themselves, the Registrable Securities
held by them and the intended method of disposition of such securities as shall
be reasonably required to effect the

- --------------------------------------------------------------------------------
REGISTRATION RIGHTS AGREEMENT                                            Page 4
<PAGE>
 
registration of their Registrable Securities and to execute such documents in
connection with such registration as the Company may reasonably request.

6.  Expenses of Demand Registration

     All expenses other than underwriting discounts and commissions and transfer
taxes incurred in connection with the underwriting, registrations, filings or
qualifications pursuant to Section 2, including, without limitation, all
registration, filing and qualification fees, printing and accounting fees, the
fees and disbursements of counsel for the Company and the fees and disbursements
of one counsel for the selling Holders shall be borne by the Company; provided,
however, that the Company shall not be required to pay for any expenses of any
registration proceeding begun pursuant to Section 2 if the registration request
is subsequently withdrawn at the request of the Holders of a majority of the
Registrable Securities to be registered (which Holders shall bear such
expenses), unless the Holders of a majority of the Registrable Securities agree
to forfeit the right to one registration pursuant to Sections 2 and 15.

7.  Expenses of Company Registration

     The Company shall bear and pay all expenses incurred in connection with any
registration, filing or qualification of Registrable Securities with respect to
the registrations pursuant to Section 3 for each Holder, including, without
limitation, all registration, filing and qualification fees, printing and
accounting fees, the fees and disbursements of counsel for the Company and the
fees and disbursements of one counsel for the selling Holders; provided,
however, that the selling Holders shall bear the expenses of any underwriting
discounts and commissions and transfer taxes relating to the Registrable
Securities.

8.  Underwriting Requirements

     The Company shall not be required under Section 3 to include any of the
Holders' securities in an underwritten offering of the Company's securities
unless such Holders accept the terms of the underwriting as agreed upon between
the Company and the underwriters selected by it.  If the total amount of
securities, including Registrable Securities, requested by shareholders to be
included in such offering exceeds the amount of securities that the underwriters
reasonably believe compatible with the success of the offering, then the Company
shall be required to include in the offering only that number of such
securities, including Registrable Securities, which the underwriters believe
will not jeopardize the success of the offering.  The securities to be included
in the registration in the event of such a reduction shall be apportioned first
to the Company, then pro rata among the selling Holders according to the total
amount of securities requested to be sold in such registration by such Holders
and then pro rata among any other selling shareholders according to the total
amount of securities otherwise entitled to be included therein owned by each
such other selling shareholder, or in such other proportions as shall mutually
be agreed to by such selling shareholders; provided that in no event shall the
amount of securities of the selling Holders included in the offering be reduced
below 20% of the total amount of securities included in such offering, unless
such offering is the initial public offering of the Company's securities, in

- --------------------------------------------------------------------------------
REGISTRATION RIGHTS AGREEMENT                                            Page 5
<PAGE>
 
which case the selling Holders may be excluded if the underwriters make the
determination described above and provided no other shareholder's securities are
included.

9.  Delay of Registration

     No Holder shall have any right to obtain or seek an injunction restraining
or otherwise delaying any such registration as the result of any controversy
that might arise with respect to the interpretation or implementation of this
Agreement.

10.  Indemnification

     In the event any Registrable Securities are included in a registration
statement under this Agreement:

          (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Act or the Securities Exchange Act of 1934, as amended (the
"1934 Act"), against any losses, claims, damages or liabilities (joint or
several) to which they may become subject under the Act, the 1934 Act or other
federal or state law, insofar as such losses, claims, damages or liabilities (or
actions in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively, a "Violation"):  (i) any
untrue statement or alleged untrue statement of a material fact contained in
such registration statement, including any preliminary prospectus or final
prospectus contained therein, in light of the circumstances under which they
were made, or any amendments or supplements thereto, (ii) the omission or
alleged omission to state therein a material fact required to be stated therein,
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any state securities law or
any rule or regulation promulgated under the Act, the 1934 Act or any state
securities law; and the Company will reimburse each such Holder, underwriter or
controlling person for any legal or other expenses reasonably incurred by them
in connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the indemnity agreement contained
in this Section 10(a) shall not apply to amounts paid in settlement of any such
loss, claim, damage, liability or action if such settlement is effected without
the consent of the Company, which consent shall not be unreasonably withheld,
nor shall the Company be liable in any such case for any such loss, claim,
damage, liability or action to the extent that it arises out of or is based upon
a Violation which occurs in reliance upon and in conformity with written
information furnished expressly for use in connection with such registration by,
or on behalf of, any such Holder, underwriter or controlling person.

          (b) To the extent permitted by law, each selling Holder will indemnify
and hold harmless the Company, each of its officers, directors, agents or
employees, each person, if any, who controls the Company within the meaning of
the Act, any underwriter and any other Holder selling securities in such
registration statement or any person who controls such Holder, against any
losses, claims, damages or liabilities (joint or several) to which the

- --------------------------------------------------------------------------------
REGISTRATION RIGHTS AGREEMENT                                            Page 6
<PAGE>
 
Company or any such officer, director, agent, employee, controlling person, or
underwriter, or other such Holder or its controlling person may become subject,
under the Act, the 1934 Act or other federal or state law, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any Violation, in each case to the extent (and only to the
extent) that such Violation occurs in reliance upon and in conformity with
written information furnished by, or on behalf of, such Holder expressly for use
in connection with such registration; and each such Holder will reimburse any
legal or other expenses reasonably incurred by the Company or any such partner,
officer, director, agent, employee, controlling person, underwriter or other
such Holder or its controlling person in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this Section 10(b) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Holder, which consent
shall not be unreasonably withheld.

          (c) Promptly after receipt by an indemnified party under this Section
10 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 10, deliver to the
indemnifying party a written notice of the commencement thereof, and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly notified, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided, however, that an indemnified party shall
have the right to retain its own counsel, with the fees and expenses to be paid
by the indemnifying party, if, in the opinion of counsel for the indemnifying
party, representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding.  The failure to deliver written notice to the
indemnifying party within a reasonable period of time of the commencement of any
such action shall relieve such indemnifying party of any liability to the
indemnified party under this Section 10 to the extent prejudicial to its ability
to defend such action, but the omission so to deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 10.

11.  Reports Under the Act

     With a view to making available to the Holders the benefits of SEC Rule 144
promulgated under the Act and any other rule or regulation of the SEC that may
at any time permit a Holder to sell securities of the Company to the public
without registration or pursuant to a registration on Form S-3, the Company
agrees to:

          (a) make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times after 90 days from the
effective date of the first registration statement filed by the Company for the
offering of its securities to the general public;

- --------------------------------------------------------------------------------
REGISTRATION RIGHTS AGREEMENT                                            Page 7
<PAGE>
 
          (b) take such action, including the voluntary registration of its
Common Stock under Section 12 of the 1934 Act, as is necessary to enable the
Holders to utilize Form S-3 for the sale of their Registrable Securities, such
action to be taken as soon as practicable after the end of the fiscal year in
which the first registration statement filed by the Company for the offering of
its securities to the general public is declared effective;

          (c) file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

          (d) furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144 (at any time
after 90 days from the effective date of the first registration statement filed
by the Company), the Act and the 1934 Act (at any time after it has become
subject to such reporting requirements), or that it qualifies as a registrant
whose securities may be resold pursuant to Form S-3 (at any time after it so
qualifies), (ii) a copy of the most recent annual or quarterly report of the
Company and such other reports and documents so filed by the Company, and (iii)
such other information as may be reasonably requested in availing any Holder of
any rule or regulation of the SEC that permits the selling of any such
securities without registration or pursuant to such form.

12.  Assignment of Registration Rights

     The rights to cause the Company to register Registrable Securities pursuant
to this Agreement may be assigned by a Holder to a transferee or assignee of
such securities who shall, upon such transfer or assignment, be deemed a
"Holder" under this Agreement; provided that the Company is, within a reasonable
period of time after such transfer, furnished with written notice of the name
and address of such transferee or assignee and the securities with respect to
which such registration rights are being assigned; provided, further, that such
assignment shall be effective only if immediately following such transfer the
further disposition of such securities by the transferee or assignee is
restricted under the Act and that such transferee or assignee is either (a) a
partner or retired partner of any Holder that is a partnership, (b) a member of
the immediate family or a trust for the benefit of any Holder that is an
individual, or (c) the transferee or assignee of at least 150,000 shares of the
Registrable Securities.

l3.  Limitations on Registration Rights

          (a) No Holder shall have the right to cause the Company to register
Registrable Securities pursuant to this Agreement if (i) such Holder holds
Registrable Securities having a fair market value of $750,000 or less or (ii)
such Registrable Securities may be sold under the Act without volume limitation
and without an effective registration statement under the Act; provided,
however, that during the five-year period after the effective date of the first
registration statement for a public offering of the Company's securities, any
Holder that continues to hold at least $5,000,000 of Registrable Securities
shall maintain such Holder's registration rights notwithstanding the provisions
at clause (ii).

- --------------------------------------------------------------------------------
REGISTRATION RIGHTS AGREEMENT                                            Page 8
<PAGE>
 
          (b) From and after the date of this Agreement, the Company shall not,
without the prior written consent of the Holders of a majority of the
outstanding Registrable Securities, enter into any agreement with any holder or
prospective holder of any securities of the Company that would allow such holder
or prospective holder to (a) include such securities in any registration filed
under Section 2, 3 or 15, unless under the terms of such agreement, such holder
or prospective holder may include such securities in any such registration only
to the extent that the inclusion of its securities will not reduce the amount of
the Registrable Securities of the Holders which is included or (b) make a demand
registration which could result in such registration statement being declared
effective prior to the earlier of either of the dates set forth in Section 2(a)
or within 180 days of the effective date of any registration effected pursuant
to Section 2.

14.  "Market Stand-Off" Agreement

     The Holders hereby agree that they shall not, to the extent requested by
the Company and an underwriter of Common Stock (or other securities) of the
Company, sell or otherwise transfer or dispose (other than to donees who agree
to be similarly bound) of any Registrable Securities for 180 days following the
effective date of a registration statement of the Company filed under the Act;
provided, however, that all officers and directors of the Company and all other
persons with registration rights (whether or not pursuant to this Agreement)
enter into similar agreements.

     In order to enforce the foregoing covenant, the Company may impose stop-
transfer instructions with respect to the Registrable Securities of the Holders
(and the shares or securities of every other person subject to the foregoing
restriction) until the end of such period.

15.  Form S-3 Registration

     In case the Company shall receive from the Holders of Registrable
Securities then outstanding a written request or requests that the Company
effect a registration on Form S-3 and any related qualification or compliance
with respect to Registrable Securities owned by such Holders, reasonably
expected to generate gross proceeds of not less than $2,000,000, the Company
will:

          (a) promptly give written notice of the proposed registration and
any related qualification or compliance to all other Holders;

          (b) as soon as practicable effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of such Holders'
Registrable Securities as are specified in such request together with all or
such portion of the Registrable Securities of any other Holders joining in such
request as are specified in a written request given within 15 days after receipt
of written notice from the Company; provided, however, that the Company
shall not be obligated to effect any such registration, qualification or
compliance pursuant to this

- --------------------------------------------------------------------------------
REGISTRATION RIGHTS AGREEMENT                                            Page 9
<PAGE>
 
Section 15: (i) if Form S-3 is not available for such offering by the Holders;
(ii) if the Company shall furnish to the Holders a certificate signed by the
President of the Company stating that, in the good faith judgment of the Board
of Directors of the Company, it would be seriously detrimental to the Company
and its shareholders for such Form S-3 registration to be effected at such time,
in which event the Company shall have the right to defer the filing of the Form
S-3 registration statement for a period of not more than 90 days after receipt
of the request of the Holders under this Section 15; provided, however, that the
Company shall not use this right more than once in any 12-month period; (iii) if
the Company has, within the six month period preceding the date of such request,
already effected one such registration on Form S-3 for the Holders pursuant to
this Section 15; (iv) if the Company within the six month period preceding the
date of such request has effected a registration of securities in which the
Holders of Registrable Securities requesting registration pursuant to this
Section 15 were entitled to participate to the fullest extent they desired
pursuant to Section 2 or 3; or (v) in any particular jurisdiction in which the
Company would be required to qualify to do business or to execute a general
consent to service of process in effecting such registration qualification or
compliance; and

          (c) subject to the foregoing, file a registration statement covering
the Registrable Securities and other securities so requested to be registered as
soon as practical after receipt of the request or requests of the Holders.  All
expenses incurred in connection with a registration requested pursuant to this
Section 15, including, without limitation, all registration, filing,
qualification, printing and accounting fees and the reasonable fees and
disbursements of one counsel for the selling Holders and counsel for the
Company, shall be borne by the Company; provided, however, that the selling
Holders shall bear the expenses of any underwriting discounts and commission and
transfer taxes relating to the securities to be registered on behalf of the
Holders.

16.  Notices

     Unless otherwise provided, any notice required or permitted under this
Agreement shall be given in writing and shall be deemed effectively given upon
personal delivery to the party to be notified or upon deposit with the United
States Post Office, postage prepaid, registered or certified with return receipt
requested and addressed to the party to be notified at the address indicated for
such party on the signature page hereof or on Schedule A hereto, or at such
other address as such party may designate by ten days' advance written notice to
the other parties given in the foregoing manner.

17.  Amendments and Waivers

     Any term of this Agreement may be amended and the observance of any term
may be waived (either generally or in a particular instance and either
retroactively or prospectively) only with the written consent of the Company and
the holders of a majority of the shares of Series A Stock and Common Stock that
are Registrable Securities themselves or upon which Registrable Securities are
based.  Additional Holders may be added to this Agreement with

- --------------------------------------------------------------------------------
REGISTRATION RIGHTS AGREEMENT                                            Page 10
<PAGE>
 
such consent by amending Schedule A hereto and adding a signature page executed
by such additional Holder.

18.  Severability

     If one or more provisions of this Agreement are held to be unenforceable
under applicable law, such provision shall be excluded from this Agreement, and
the balance of this Agreement shall be interpreted as if such provision were so
excluded and shall be enforceable in accordance with its terms.

19.  Governing Law

     This Agreement shall be governed by and construed under the laws of the
State of Washington as applied to agreements among Washington residents entered
into and to be performed entirely within the State of Washington.

20.  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 and
the same instrument.

21.  Entire Agreement

     This Agreement constitutes the full and entire understanding and agreement
between the parties with respect to the subject matter hereof and supersedes all
prior agreements with respect to the subject matter hereof.

opinion of the Company's accountants, such exercise would render unavailable to
the Company any "pooling of interest" accounting).

promote, market and demonstrate the Software.

With respect to paragraph (b) above, the parties acknowledge that the rights of
Authorized End-Users under the Software License Agreement with respect to the
Software and the Documentation may in certain respects exceed the distribution
and reproduction rights granted to Distributor under this Agreement;

2.2  Reservation.  Primus reserves all rights to the Software, Documentation,
     -----------

has no rights to, and shall not translate any of the Software or the
Documentation.

          2.2.2  Media.   Distributor may only distribute the Software to 
                 -----  
Authorized End-Users and Authorized Evaluators on the following media: CD-ROM;

          2.2.3  Sub-distributors.  With the prior written consent of Primus,
                 ----------------

any other Entity with respect to whose appointment as a sub-distributor Primus
has consented in writing, such consent not to be unreasonably withheld or
delayed; provided, however, that Distributor's Subsidiaries shall have no sub-
licensing right, except for sub-licenses to Authorized Evaluators and Authorized
End-Users.  Primus hereby approves Distributor's appointment of Primus K.K. as a
sub-distributor under this Agreement. Distributor shall ensure that every sub-
distributor complies with the obligations of Distributor under this Agreement,
as though such obligations applied directly to the sub-distributor.  Distributor
shall make Primus a third-party beneficiary of Distributor's rights with respect
to its sub-distributors, and of the obligations of each such sub-distributor.
Distributor shall ensure that all sub-distribution appointments shall terminate
upon termination of the Distribution Term, and that all license rights sub-
licensed to sub-distributors by Distributor terminate on expiration of the
Distribution Term, in each case without any liability on the part of Primus.

          2.2.4  Marketing And Promotion Over The Internet.  Notwithstanding the
                 -----------------------------------------                      
exclusivity of Distributor's distribution license, and the restriction to the
Exclusive Territory of the licenses granted by Primus to Distributor, each of
Primus and Distributor may promote and market their products over the Internet
in any language.  If an Entity to whom Distributor's exclusive license applies
contacts Primus concerning the Software, Primus shall refer that Entity to
Distributor.  Likewise, if an Entity to whom Distributor's license does not
apply contacts Distributor concerning the Software, Distributor shall refer that
Entity to Primus.  Each of Primus and Distributor may incorporate a hyper-link
to the other's web-site in their web-sites with the prior written consent of the
other.  Such consent may not be unreasonably withheld, and may be revoked by
either party at any time upon reasonable grounds.

          2.2.5  Reproduction Policy.  Within two months of execution of this 
                 -------------------      
Agreement, Primus and Distributor shall mutually determine a policy for
management of copies of the Software created by Distributor. The policy shall
address, at a minimum, internal and external serialization, markings,
encryption, license management software and license files. Nothing in the policy
shall entitle Primus to influence or direct Distributor's targeting and
selection of customers for the Software. Distributor and Primus shall comply
with the policy.

          2.2.6  No Conveyance of Ownership; Trade Secrets.  This Agreement

which the Software or Documentation is stored. Title to copies of the Software
and the Documentation delivered to Distributor, sub-distributors and Authorized
Evaluators and Authorized End-Users shall remain with Primus at all times.
Accordingly, Distributor's order and receipt of Software and documentation shall
not transfer any title to the Software or the Documentation, but only confer
upon Distributor the right to transfer possession of them to its sub-
distributors and Authorized Evaluators and Authorized End-Users. Distributor
acknowledges that the Software, the Documentation and the Confidential
Information constitute trade secrets and are the valuable property of Primus and
its licensors, and that the Software and Documentation are protected by
copyright and trademark rights.

          2.2.7  Reverse Engineering.  Distributor shall not decompile, or 
                 -------------------      
create or attempt to create, by reverse engineering or otherwise, the source
code from the object code supplied under this Agreement or use it to create a
derivative work, except to the extent necessary to use the source code as
provided in Section 4.6.2 (Source Code Escrow Release).
                                                                   Confidential

     2.2.8 Rights to Acquire Software. Distributor shall not grant to any Entity
           -------------------------- 
any rights to sub-license the Software and/or the Documentation that (a) can be
exercised more than six (6) months after such Entity first executes a Software
License Agreement, except with the prior written approval of Primus, such
approval not to be unreasonably withheld or delayed, and (b) entitle such Entity
to use the Software and/or Documentation for a license fee of less than [*] US
Dollars (US $[*]) per Authorized Workstation. If, in consequence of exercise of
any such right, Distributor would be obligated to provide such Entity with
rights to more Authorized Workstations than those for which Distributor has paid
license fees under this Agreement then, at Primus' sole and absolute discretion,
Primus shall either (x) assume (and Distributor shall assign) such obligations,
or (y) increase the number of Authorized Workstations licensed to Distributor
under this Agreement and, to the extent necessary, extend the Distribution Term
on a non-exclusive basis upon receipt from Distributor of a license fee per
Authorized Workstation of [*] US Dollars (US $[*]).

(a) the location, model name, and serial number of all servers on which the
Software is installed, (b) the number of installations of the client portion of
the Software made by Distributor, any sub-distributor, Authorized Evaluator
and/or any Authorized End-User, and (c) invoicing and payment of Authorized End-
Users' support and maintenance fees (collectively, "Distribution Records"). To
the extent that Distribution Records relate to activities carried on by
Authorized End-Users and Authorized Evaluators, Distributor and its sub-
distributors shall only be obligated to keep such records to the best of their
knowledge. Distributor shall provide such information to Primus within ten (10)
days of Primus' written request; provided, however, that Primus may not request
such information more frequently than once per quarter.

     3.7.2 Audit Rights. Upon ten (10) days prior written notice, Primus may, by
an Independent Auditor (as defined below), inspect, audit, and copy the
Distribution Records and, to the extent provided by the Software License
Agreement, and except as restricted by applicable local law, access the servers
of Distributor, its sub-distributors and of Authorized End-Users on which the
Software is installed, at any time during the regular business hours of the user
thereof, but only for the purposes of determining that Primus has been properly
paid all fees to which it is entitled under this Agreement. Unless an audit
discloses a material discrepancy in favor of Distributor or any of its sub-
distributors, Primus (i) may exercise such audit rights no more than once during
any twelve (12) month period, and (ii) shall pay Distributor's reasonable
expenses incurred with respect to the audit. In the event of any understatement
of the license fees due, Distributor shall promptly pay such fees based upon the
fee per Authorized Workstation paid by Distributor under this Agreement, and
Primus will extend this Agreement to correct
                                                                   Confidential

prejudice to any other rights or remedies of Primus under this Agreement or
applicable law.

public accounting firm mutually acceptable to Distributor and Primus. If
Distributor and Primus cannot agree on the identity of the Independent Auditor,
they shall each require their own respective accounting firms to jointly

to the other. The Independent Auditor shall have executed a Non-Disclosure
Agreement prohibiting it from disclosing each of Primus' and Distributor's
Confidential Information to third parties, except as may be necessary to enforce
this Agreement. The Independent Auditor shall act as expert and not as
arbitrator.

     3.7.4 Log Files. Upon written request by Primus, Distributor shall, to the
extent provided by the Software License Agreement, and except as restricted by
applicable local law, transmit to Primus a current, complete and correct copy of
the log file for each server of Distributor, its sub-distributors and of
Authorized End-Users on which the Software is installed; provided, however, that
unless review of a log file has indicated additional fees are due to Primus,
Primus (i) may not request a copy of the log file more frequently than once a
quarter, and (ii) shall pay Distributor's reasonable expenses incurred with
respect to such transmission.

3.8  Governmental Compliance.  Distributor shall obtain and maintain all
     -----------------------

its obligations under this Agreement, including without limitation those
required for (a) Distributor's appointment as distributor; (b) Distributor's
status as a licensee under Primus' intellectual property rights; (c) the import
of the Software into those parts of the Exclusive Territory in or to which
Distributor is marketing or distributing the Software; and (d) the marketing,
distribution and licensing of the Software within those parts of the Exclusive
Territory in or to which Distributor is marketing or distributing the Software.
Distributor shall be solely responsible for compliance with any foreign exchange
controls affecting the Exclusive Territory applicable to its activities. All and
any regulatory and other approvals which are obtained for the Software by

Except for approval of the Japan Fair Trade Commission, Distributor has
represented to Primus that no regulatory approvals which have not already been

3.9.4

     3.9.5  Early Termination.  If any claim of infringement of any third party
            -----------------                                                  
intellectual property right materially adversely impairs Distributor's ability
to market the Software, and such impairment is continuing for more than three
(3) months, then Distributor, after consultation with Primus, may terminate the
Distribution Term.  Primus shall pay Distributor the Early Termination Amount

4.2  Training.  During the Distribution Term, Primus shall provide Distributor
     --------                                                                 
with such training as Primus and Distributor mutually determine is necessary, at

     --------                                                         
Distributor with Upgrades if and when they are available.  Distributor shall pay
Primus Upgrade fees as set forth in Schedule 3(a).  Distributor shall not

support available between 8.30am and 5.30pm PST/PDT, and otherwise at times
which are mutually convenient for Primus and Distributor, taking into account
the urgency of the situation. Primus shall provide such support in a good,
professional and workmanlike manner, consistent with industry standards. In the
event that the Software requires modification in order to remedy any Error (as
defined below), Primus shall provide Distributor with a Fix (as defined below)
or a Workaround (as defined below) as soon as reasonably practicable. "Error"
means any failure of the Software to conform in any material aspects to its

licenses, permits, certificates and authorizations, including without limitation
export licenses, needed for the manufacture of the Software in the USA, and the
export of the Software from the USA to Distributor (but not the re-export of the
Software by Distributor).  Primus shall provide the US export class number of
the Software to Distributor within thirty (30) days of the date of this
Agreement.

4.6  Source Code Escrow.
     ------------------ 

     4.6.1 Deposit. Primus shall, at all times, maintain the source code for the
Software in escrow. Licensee shall be named as a FLEXSAFE beneficiary in

entered into with Data Securities International, a copy of which is attached
hereto as Schedule 7. Primus shall deposit all source code for the Software and
all Upgrades into the escrow account.

     4.6.2 Release. If (a) (i) Primus ceases to provide Fixes or Workarounds (as
defined in Section 3.3.2) for the versions of the Software then in use by
Distributor's sub-licensees ("Relevant Versions"), (ii) such Fixes or
Workarounds are not provided by any other Entity, and (iii) Distributor is
obligated to provide such Fixes or Workarounds to Authorized End-Users, or (b)
(i) the Software does not comply with applicable specifications in the
Documentation with the result that Distributor's ability to market and
distribute the Software is materially adversely impaired, (ii) such non-
compliance is continuing for a period in excess of two (2) months following the
provision by Distributor to Primus of explicit written notice detailing the
scope and nature of the non-compliance, and the precise circumstances in which
the non-compliance occurred, and (iii) Distributor has used its commercially
reasonable best efforts to replicate the circumstances surrounding the non-
compliance and provided Primus with such other information and materials to fix
the non-compliance as Primus has reasonably requested, then Primus shall grant
Distributor a perpetual, non-exclusive, non-transferable license, without right
to sub-license, to copy, distribute, modify and use Primus' source code for the
Relevant Versions at Distributor's corporate headquarters, solely to operate and
maintain the Software for use and licensing in accordance with the provisions of
this Agreement. Distributor shall treat the source code with at least the same
degree of care and security as it treats its own commercially valuable source
code. PRIMUS' ONLY WARANTY WITH RESPECT TO THE SOURCE CODE SHALL BE THAT IT IS
AN ACCURATE COPY OF PRIMUS' SOURCE CODE FOR THE CURRENT VERSION OF THE SOFTWARE
AFFECTED AND INCLUDES NOTES AND RELATED DOCUMENTATION ONLY TO THE EXTENT IN
PRIMUS' POSSESSION OR CONTROL, AND PRIMUS EXPRESSLY DISCLAIMS ALL AND ANY
IMPLIED WARRANTIES RELATING TO THE SOURCE CODE.

     ---------------                                                    
mutually determine policies to be followed by each of them to minimize
unauthorized reproduction and/or distribution of the Software within the
Exclusive Territory.
                                                                   Confidential

Distributor shall, by written election to Primus within twenty (20) days of
delivery of the Primus Election, elect either (a) to retain its licensing and
sub-licensing rights under this Agreement on a non-exclusive basis, or (b) to
accept the Early Termination Amount in full and final settlement of any claim
Distributor may have with respect to any liability in any part of the Exclusive

shall submit a purchase order to Distributor for the quantity of additional
Authorized Workstations desired at the rates and in the minimum blocks for
increasing licensed usage specified in Exhibit A.  If no rate or minimum is
specified, Distributor and Licensee shall work together to determine a mutually
satisfactory rate and minimum purchase amount (if any), and shall execute an
additional Exhibit to this Agreement reflecting such terms. Upon Distributor's
notification of acceptance of Licensee's purchase order, Licensee may install
the Client Software on such additional Authorized Workstations.

4.3  Sales Taxes, Etc.  Licensee shall be responsible for any applicable sales,
     ----------------                                                          
use, or any value added or similar taxes payable with respect to the licensing
of the Software to Licensee, or arising out of or in connection with this
Agreement, other than taxes imposed in Japan based upon Distributor's income.
If Licensee has tax-exempt status, Licensee shall provide written evidence of
such status with its purchase orders.

4.4  Accounting.  Licensee shall keep current, complete and accurate records
     ----------                                                             
regarding the location, model name, and serial number of all Authorized Servers
on which the Server Software is installed and the number of installations of the
Client Software made by Licensee and any Authorized User.  Licensee shall
provide such information to Distributor within 5 days of Distributor's written
request. Upon 5 days prior written notice, Distributor, Distributor's Licensors
and/or their representatives may inspect, audit, and copy such records of
Licensee and access the Server Software at any of Licensee's relevant locations
and/or Licensed Sites,  at any time during Licensee's regular business hours.
Unless an audit discloses a material discrepancy in Licensee's favor, such audit
rights may be exercised no more than once during any 12 month period.  In the
event of any understatement of the license fees due, Licensee shall promptly pay
such fees based upon Distributor's then current list price, and Distributor will
extend this License to correct any such deficiency.  Distributor's acceptance of
any payment shall be without prejudice to any other rights or remedies of
Distributor and/or Distributor's Licensors under this Agreement or applicable
law.  Upon written request by Distributor, Licensee shall transmit a current,
complete and correct copy of the log file for each copy of the Server Software
to Distributor; provided, however, that Distributor may not request a copy of
the log file more frequently than once a quarter, unless review of a log file
has indicated additional fees are due to Distributor.

Section 5.  Additional Rights And Obligations.
- ----------  --------------------------------- 

5.1   Increase in Authorized Servers.  In the event that Licensee wishes to
      ------------------------------                                       
increase the number of Authorized Servers, Licensee shall provide Distributor
with written notice of (i) the quantity of additional Authorized Servers
desired, (ii) the model and serial number on which the Server Software is to be
installed and (iii) the location of the Licensed Site.  Upon written acceptance
by Distributor, Licensee may install the Server Software on such additional
Authorized Servers.  Distributor and Licensee shall amend Exhibit A accordingly.

5.2  Data Protection. Licensee shall maintain current back-up copies of all of
     ---------------                                                          
Licensee's data used in connection with the Software.

5.3  Reference.  Licensee authorizes Distributor and Distributor's Licensors to
     ---------                                                                 
disclose that Licensee is a customer and agrees to be a reference account for
Distributor and for Distributor's Licensors with respect to the Software.

5.4  Third Party Rights.  The Software incorporates material which is licensed
     ------------------                                                       
by Primus from third parties and which is used by agreement between Primus and
such third parties. Licensee acknowledges and agrees that any third party
licensor of such material is a direct and intended third party beneficiary of
this Agreement who may enforce this Agreement directly against Licensee.

5.5  Confidential Information.  Neither Distributor nor Licensee shall, with
     ------------------------                                               
respect to any Confidential Information which one of them (a "Recipient")
receives from the other (a "Discloser"), at any time, without the express prior
written consent of Discloser, disclose or otherwise make known or available to
any person or entity other than Discloser, or use for Recipient's own account,
any of Discloser's Confidential Information.  Recipient shall use all reasonable
procedures to safeguard Discloser's Confidential Information.

5.6  Compliance With Law.  Licensee shall comply with all applicable laws and
     -------------------                                                     
regulations in its use of the Software and Documentation.  Without limiting the
generality of the foregoing, Licensee shall not export or re-export, directly or
indirectly, any Software in violation of any US export control laws and
regulation and shall promptly provide Distributor and/or Primus with any "letter
of assurance" required by Distributor and/or Primus pursuant to such laws and
regulations.

5.7  Protection Against Unauthorized Use.  Licensee shall promptly notify
     -----------------------------------                                 
Distributor and Distributor's Licensors of any unauthorized use of any Software
of which Licensee becomes aware.  In the event of any unauthorized use by any
Authorized User (or by any employee or contractor of Licensee or of any
Authorized User), Licensee shall use its commercially reasonable best efforts to
immediately terminate and prevent further occurrences of such unauthorized use.
In the event that Licensee commences any legal proceeding in connection with
such unauthorized use, Distributor and/or Distributor's Licensors may, at their
option and

                                  Page 2 of 6
<PAGE>
 
expense, participate in any such proceeding. In such event, Licensee,
Distributor and Distributor's Licensors shall each provide the other with such
authority, information and assistance related to such proceeding as may be
reasonably necessary to safeguard the interests of Distributor and/or
Distributor's Licensors, and Licensee's rights under this Agreement.

5.8  Miscellaneous Provisions.  Dispute resolution and other provisions are
     ------------------------                                              
contained in Schedule 1 to this Agreement.

Section 6.  Distributor's Warranties; Remedies.
- ----------  ---------------------------------- 
6.1  Warranties.
     ---------- 

  6.1.1  Media.  Distributor warrants to Licensee that the media on which the
Software is delivered by Distributor to Licensee will be free from defects in
materials and workmanship for a period of ninety (90) days beginning on the date
of shipment by Distributor.

  6.1.2  Performance.  Distributor warrants to Licensee that the Software as
delivered by Distributor to Licensee shall perform in all material respects in
accordance with the applicable specifications set forth in the Documentation for
a period of ninety (90) days beginning on the date of shipment by Distributor.

  6.1.3  Infringement.  Distributor warrants to Licensee that use in accordance
with this Agreement of the Software as delivered by Distributor to Licensee does
not infringe any valid copyright, patent or trademark existing under the laws of
the United States and/or Japan.

  6.1.4  Authority.  Distributor warrants to Licensee that Distributor has all
requisite corporate authority to execute and deliver this Agreement, and that
the execution, delivery and performance of this Agreement by Distributor does
not conflict with any obligation of Distributor under any agreement or
instrument to which Distributor is a party or by which it is bound.

  6.1.5  Bugs and Abatement.  Without limiting the foregoing, Distributor does
not warrant that the Software is free from all bugs, errors, or omissions.  The
warranties in this Section 6.1 shall automatically abate to the extent that the
Software has been damaged, abused, modified, or combined with other software by
persons other than Distributor's authorized employees or representatives, or
other than at Distributor's express direction.

6.2  Performance Remedy.  If any Software fails to comply with the warranties
     ------------------                                                      
set forth in Sections 6.1.1 and 6.1.2 and Licensee provides written notice of
the non-compliance to Distributor within the warranty period, then Distributor
will either repair or, at its option, replace any non-complying media or
Software.  If Distributor is unable to correct the noncompliance within sixty
(60) days of receipt of such written notice from Licensee, Distributor shall
(i), with respect to non-compliant Initial Software, promptly refund all of the
License fees paid for such Software, and (ii), with respect to non-compliant New
Software, promptly refund all of the most recent annual Support and Maintenance
Agreement fee attributable to the development of New Software, together with a
pro-rated amount of the annual fee reflecting the unused portion of the annual
term, in each case (i) and (ii) in full and final satisfaction of all and any of
Licensee's claims arising out of media or Software failure, and immediately
terminate the License or Support and Maintenance Agreement, as the case may be.

6.3  Infringement Remedy.  Distributor shall defend and indemnify Licensee
     -------------------                                                  
against any proceeding based upon any failure to satisfy the warranty set forth
in Section 6.1.3, provided that (a) Licensee shall notify Distributor and
Distributor's Licensors in writing of any claim of infringement promptly after
it has been made, (b) Distributor and Distributor's Licensors shall have
exclusive control over the defense and settlement of the proceeding, (c)
Licensee shall provide such assistance in defense of the proceeding as
Distributor and Distributor's Licensors may reasonably request, at Distributor's
and Distributor's Licensors' reasonable expense, and (d) Licensee shall comply
with any settlement or court order made in connection with the proceeding.  In
the event that use of the Software becomes, or in Distributor's and/or
Distributor's Licensors' reasonable opinion is likely to become, the subject of
a claim of infringement of any intellectual property right of any third party,
Distributor and Distributor's Licensors shall have the right to : (i) procure
the continuing right of Licensee to use the Software; (ii) replace or modify the
Software in a functionally equivalent manner so that it no longer infringes; or
(iii) terminate the License and refund to Licensee an amount equal to the
depreciated License fee paid by Licensee (calculated on a straight line basis
over a five (5) year life).

6.4  Warranties Repeated For Replacements and New Software.  The warranties and
     -----------------------------------------------------                     
other provisions of this Section 6 shall be automatically repeated for any
modifications of the Software delivered to remedy any non-compliance with the
warranties under Sections 6.1 and for any New Software, in each case upon
shipment of the same to Licensee by Distributor.

6.5  Disclaimer Of Implied Warranties.  Distributor and Distributor's Licensors
     --------------------------------                                          
make no representation or warranty in connection with the Initial Software and
New Software, except as set forth in Section 6.1.  EXCEPT AS SPECIFICALLY SET
FORTH IN THIS SECTION 6, DISTRIBUTOR AND DISTRIBUTOR'S LICENSORS DISCLAIM AND
LICENSEE WAIVES AND RELEASES ALL RIGHTS AND REMEDIES OF LICENSEE, AND ALL
WARRANTIES, OBLIGATIONS, AND LIABILITIES OF DISTRIBUTOR AND/OR DISTRIBUTOR'S
LICENSORS, EXPRESS OR IMPLIED, ARISING BY LAW OR OTHERWISE, WITH RESPECT TO ANY
BUG, ERROR, OMISSION, DEFECT, DEFICIENCY, OR NONCONFORMITY IN ANY SOFTWARE OR
OTHER ITEMS FURNISHED UNDER THIS AGREEMENT OR THE SUPPORT AND MAINTENANCE
AGREEMENT, INCLUDING BUT NOT LIMITED TO ANY: (A) IMPLIED WARRANTY OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE; (B) IMPLIED WARRANTY
ARISING FROM COURSE OF PERFORMANCE, COURSE OF DEALING, OR USAGE OF TRADE; OR (C)
CLAIM OF INFRINGEMENT.

Section 7  Term and Termination.
- ---------  -------------------- 

7.1  License Term.  The License Term shall commence upon the date of this
     ------------                                                        
Agreement and shall continue in perpetuity unless the Agreement is terminated in
accordance with Section 7.3.

7.2  Distribution Term.  If no Distribution Term is specified in Exhibit A, the
     -----------------                                                         
Distribution Term shall be the same as the License Term.  The Distribution Term,
if specified in Exhibit A, shall commence upon the date of this Agreement for
Software identified in Exhibit A as being subject to the Distribution Term and,
subject to earlier termination of this Agreement in accordance with Section 7.3,
shall expire as specified in Exhibit A.  Expiration of the Distribution Term
shall not in and of itself automatically terminate the right of Licensee and/or
Authorized Users to continue to use the Software and Documentation pursuant to
Section 2 above.

7.3  Termination On Breach.  In the event of a material breach or default under
     ---------------------                                                     
this Agreement by either party, the non-breaching party may terminate this
Agreement by giving the breaching party written notice of the breach or default
and the non-breaching party's intention to terminate.  The Agreement shall
automatically terminate thirty (30) days after delivery of such notice, unless
the breaching party cures the breach or default before the expiration of the
thirty (30) day period.

7.4  Post Termination Obligations.  Following termination of this Agreement,
     ----------------------------                                           
howsoever arising, Licensee shall destroy all copies of the Server Software
within five (5) days of such termination, and all copies of the Client Software
and the Documentation within twenty (20) days of such termination, and
immediately thereafter provide Distributor and Primus with a written
certification signed by an authorized representative of Licensee certifying that
all copies of the Software have been destroyed and all use of the Software has
been discontinued.  The provisions of  Section 5.5 (Confidential Information)
shall survive termination of this Agreement.

                                   SCHEDULE 1
                    DISPUTE RESOLUTION AND OTHER PROVISIONS
                                        
1.  Dispute Resolution.
    ------------------ 

1.1  Governing Law.  This Agreement shall be governed by and interpreted in
accordance with the internal laws of the State of Washington, and, where such
laws are preempted by the laws of the United States, by the internal laws of the
United States, in each case without regard to (a) conflicts of laws principles
and renvoi and (b) the applicability, if any, of the United Nations Convention
on Contracts for the International Sale of Goods.

1.2  Mediation.  In the event of any controversy or claim arising out of or
relating to this Agreement or the breach or interpretation thereof, the parties
shall, upon five days notice from either one to the other, submit themselves and
the subject-matter of the dispute to mediation before an independent mediator to
be appointed by the head office of the American Arbitration Association.  Costs
of mediation shall be borne equally between the parties.

1.3  Arbitration.  In the event that the parties remain in dispute following the
mediation, the controversy or claim shall be determined by arbitration in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association by a single, disinterested arbitrator appointed in accordance with
such Rules.  The determination of the arbitrator shall be final, conclusive and
binding.  Judgment upon the award rendered may be entered in any court of any
state or country having jurisdiction.

1.4  Conduct.  Each party shall ensure that any mediation and arbitration are
conducted as speedily as is reasonably possible, and that all and any
information disclosed during or in connection with the arbitration is treated by
each party with the strictest confidence.

1.5  Interim and Permanent Relief.  Upon the application of either party to this
Agreement, and whether or not an arbitration or mediation has yet been
initiated, all courts having jurisdiction over one or more of the parties are
authorized to: (i) issue and enforce in any lawful manner such temporary
restraining orders, preliminary injunctions and other interim measures of relief
as may be necessary to prevent harm to a party's interests or as otherwise may
be appropriate pending the conclusion of arbitration proceedings pursuant to
this Agreement; and (ii) enter and enforce in any lawful manner such judgments
for permanent equitable relief as may be necessary to prevent harm to a party's
interests or as otherwise may be appropriate following the issuance of arbitral
awards pursuant to this Agreement.

1.6  Venue.  Any mediation or arbitration conducted under or in connection with
this Agreement shall take place in Seattle, Washington at a time and location to
be determined by the mediator or arbitrator, as the case may be.

1.7  Legal Expenses.  If any proceeding is brought by either party to enforce or
interpret any term or provision of this Agreement, the substantially prevailing
party in such proceeding shall be entitled to recover, in addition to all other
relief arising out of this Agreement, such party's reasonable attorneys' and
other experts' (including without limitation accountants) fees and expenses.

2.  Excused Performance; Force Majeure.  If the performance of this Agreement is
    ----------------------------------                                          
adversely restricted by reason of any circumstances beyond the reasonable
control and without the fault or negligence of the party affected, then the
party affected, upon giving prompt written notice to the other party, shall be
excused from such performance on a day-to-day basis to the extent of such
restriction (and the other party shall likewise be excused from performance of
its obligations on a day-to-day basis to the extent such party's obligations
relate to the performance so restricted); provided, however, that the party so
affected shall use all commercially reasonable efforts to avoid or remove such
causes of non-performance and both parties shall proceed whenever such causes
are removed or cease.

3.  Exclusion of Certain Claims.  IN NO EVENT SHALL DISTRIBUTOR OR DISTRIBUTORS'
    ---------------------------                                                 
LICENSORS BE LIABLE (WHETHER IN TORT OR CONTRACT, UNDER STATUTE OR OTHERWISE)
FOR ANY INDIRECT, SPECIAL,  CONSEQUENTIAL OR INCIDENTAL DAMAGES, INCLUDING
WITHOUT LIMITATION DAMAGES FOR LOSS OF PROFITS, BUSINESS INTERRUPTION, LOSS OF
INFORMATION AND THE LIKE, ARISING OUT OF ITS PERFORMANCE OR NONPERFORMANCE OF
THIS AGREEMENT OR THE USE, INABILITY TO USE OR RESULTS OF USE OF THE SOFTWARE,
EVEN IF DISTRIBUTOR AND/OR DISTRIBUTORS' LICENSORS HAVE BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

4.  Limitation of Liability.  Except for Distributor's obligations under Section
    -----------------------                                                     
6.3, Distributor's liability and that of Distributor's Licensors (whether in
tort or contract, under statute or otherwise) with regard to this Agreement or
any Software or other items furnished in connection with this Agreement shall in
no event exceed the license fees paid by Licensee to Distributor under this
Agreement.

5.  Equitable Relief.  Each of Licensee and Distributor acknowledges that
    ----------------                                                     
damages will be an inadequate remedy if the other violates the terms of this
Agreement pertaining to protection of intellectual property rights, or otherwise
fails to perform its obligations hereunder.  Accordingly, subject to Section 1
of this Schedule, Licensee, Distributor and Primus shall have the right, in
addition to any other rights each of them may have, to obtain in any court of
competent jurisdiction, temporary, preliminary and permanent injunctive relief
to restrain any breach, threatened breach, or otherwise to specifically enforce

for permanent equitable relief as may be necessary to prevent harm to a party's
interests or as otherwise may be appropriate following the issuance of arbitral
awards pursuant to this Agreement.

1.6 Venue. Any mediation or arbitration conducted under or in connection with
this Agreement shall take place in Seattle, Washington at a time and location to
be determined by the mediator or arbitrator, as the case may be.

1.7 Legal Expenses. If any proceeding is brought by either party to enforce or
interpret any term or provision of this Agreement, the substantially prevailing
party in such proceeding shall be entitled to recover, in addition to all other
relief arising out of this Agreement, such party's reasonable attorneys' and
other experts' (including without limitation accountants) fees and expenses.

2. Excused Performance; Force Majeure. If the performance of this Agreement is
   ----------------------------------
adversely restricted by reason of any circumstances beyond the reasonable
control and without the fault or negligence of the party affected, then the
party affected, upon giving prompt written notice to the other party, shall be
excused from such performance on a day-to-day basis to the extent of such
restriction (and the other party shall likewise be excused from performance of
its obligations on a day-to-day basis to the extent such party's obligations
relate to the performance so restricted); provided, however, that the party so
affected shall use all commercially reasonable efforts to avoid or remove such
causes of non-performance and both parties shall proceed whenever such causes
are removed or cease.

3. Exclusion of Certain Claims. IN NO EVENT SHALL ANY OF DISTRIBUTOR,
   ---------------------------
DISTRIBUTORS' LICENSORS OR LICENSEE BE LIABLE (WHETHER IN TORT OR CONTRACT,
UNDER STATUTE OR OTHERWISE) FOR ANY INDIRECT, SPECIAL, CONSEQUENTIAL OR
INCIDENTAL DAMAGES, INCLUDING WITHOUT LIMITATION DAMAGES FOR LOSS OF PROFITS,
BUSINESS INTERRUPTION, LOSS OF INFORMATION AND THE LIKE, ARISING OUT OF ITS
PERFORMANCE OR NONPERFORMANCE OF THIS AGREEMENT OR THE USE, INABILITY TO USE OR
RESULTS OF USE OF THE LICENSED PROGRAMS OR THE SOFTWARE, EVEN IF IT HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

4. Limitation of Liability. The liability (whether in tort or contract, under
   -----------------------
statute or otherwise) of Distributor and Distributor's Licensors with regard to
this Agreement or any Licensed Programs, Software or other items furnished in
connection with this Agreement shall in no event exceed the support and
maintenance fees paid by Licensee to Distributor under this Agreement.

5. Equitable Relief. Each of Licensee and Distributor acknowledges that damages
   ----------------
will be an inadequate remedy if the other violates the terms of this Agreement,
or otherwise fails to perform its obligations hereunder. Accordingly, subject to
Section 1 of this Schedule, each of them and Distributor's Licensors shall have
the right, in addition to any other rights each of them may have, to obtain in
any court of competent jurisdiction, temporary, preliminary and permanent
injunctive relief to restrain any breach, threatened breach, or otherwise to
specifically enforce any of the obligations in this Agreement.

6. Waiver. No waiver of or with respect to any provision of this Agreement, nor
   ------
consent by a party to the breach of or departure from any provision of this
Agreement, shall in any event be binding on or effective against such party
unless it be in writing and signed by such party, and then such waiver shall be
effective only in the specific instance and for the purpose for which given.

7. Captions and Headings. The captions and headings are inserted in this
   ---------------------
Agreement for convenience only, and shall not be deemed to limit or describe the
scope or intent of any provision of this Agreement.

8. Severability; Invalidity. If any provision of this Agreement is held to be
   ------------------------
invalid, such invalidity shall not render invalid the remainder of this
Agreement or the remainder of which such invalid provision is a part. If any
provision of this Agreement is so broad as to be held unenforceable, such
provision shall be interpreted to be only so broad as is enforceable.

9. Assignment. Licensee shall not assign any of its rights this Agreement
   ----------
without the prior written consent of Distributor, which shall not be
unreasonably withheld. Subject to the foregoing restriction on assignment by
Licensee, this Agreement shall be binding upon, inure to the benefit of and be
enforceable by the parties and their respective successors and assigns.

10. Notices. Any notice or other communication under this Agreement given by
    -------
either party to the other party shall be deemed to be properly given if given in
writing and delivered (i) by facsimile transmission (receipt confirmed) or (ii)
delivered, if in Japan, by nationally recognized overnight courier, and if
outside Japan, by internationally recognized overnight courier (e.g., DHL),
properly addressed and prepaid, to the recipient at the address identified in
its signature block to this Agreement and, in the case of Primus, to Primus
Communications Corporation, Attn: Corporate Attorney, 1601, Fifth Avenue, Ste.
1900, Seattle, WA 98101, U.S.A. Any party may from time to time change its
address by giving the other parties notice of the change in accordance with this
Section.

11. Entire Agreement; Amendments. This Agreement constitutes and embodies the
    ----------------------------
entire agreement and understanding between the parties with respect to the
subject matter hereof and supersedes all prior or

                                  Page 4 of 4
<PAGE>
 
contemporaneous written, electronic or oral communications, agreements or
understandings between the parties with respect thereto. This Agreement may not
be modified or amended except by a written instrument executed by the parties.

                       PRIMUS COMMUNICATIONS CORPORATION
                    EXCLUSIVE DISTRIBUTION LICENSE AGREEMENT

                                   SCHEDULE 5
                          Primus' Software Warranties
                          ---------------------------

1.  Warranties.
    ---------- 
    1.1. Media. Primus warrants to Distributor that the media on which the
         -----                                                             
Software is delivered by Primus to Distributor will be free from defects in
materials and workmanship for a period of ninety (90) days beginning on the date
of shipment by Primus.

    1.2. Performance. During the Distribution Term with respect to Distributor,
         -----------                                                           
and for the applicable warranty period with respect to each sub-licensee that
executes a Software License Agreement with Distributor, Primus warrants to
Distributor that the Software as delivered by Primus to Distributor shall
perform in all material respects in accordance with the applicable
specifications set forth in the Documentation (and with such other
specifications as may be agreed upon in writing by Primus and Distributor).

    1.3. Infringement.  Primus warrants to Distributor that use, reproduction,
         ------------                                                         
marketing and distribution in accordance with this Agreement of the Software as
delivered by Primus to Distributor does not infringe any valid copyright,
patent, trademark or trade secret existing under the laws of the United States
or any country within the Exclusive Territory.

    1.4 Year 2000. Primus warrants to Distributor that the Software as delivered
        ---------  
by Primus to Distributor does not depend upon any internal date or time fields
which would give rise to a Software malfunction upon the transition from the
year 1999 to 2000, or upon any other date transition from the date of the
Agreement through the year 2010 where Distributor is marketing or to which
Distributor is shipping the Software.

    1.5 Viruses.  Distributor has expressed a concern that the Software should
        -------                                                               
not contain any virus.  Accordingly, Primus warrants that, to the best of its
knowledge after reasonable investigation, no material portion of the Software as
delivered by Primus to Distributor will, other than under the control of
Distributor or Authorized End-Users or Authorized Evaluators, (1) at some
specific time or upon a specific instruction or occurrence of a given event,
materially adversely stop, limit or interfere with the operation of the Software
in conformity with the Documentation, or (2) materially adversely damage, alter
or render inaccessible the Software, or any other hardware, software, data
attached to, resident on, or accessible to the system on which the Software is
executed or stored.

2.  Bugs and Abatement.  Without limiting the foregoing, Primus does not warrant
    ------------------                                                          
that the Software is free from all bugs, errors, or omissions.  Losses for which
Distributor would be entitled to compensation as a result of Primus' non-
compliance with the warranties in this Schedule 5 shall automatically abate to
the extent they are caused by the fact that the Software has been damaged,
abused, modified, or combined with other software by persons other than Primus'
authorized employees or representatives, or other than at Primus' express
direction.

3.  Performance Remedy.  If any Software fails to comply with the warranties set
    ------------------                                                          
forth in Paragraphs 1.1, 1.2, 1.4 and 1.5 above and (a) Distributor provides
written notice of the scope and nature of such non-compliance to Primus within
the warranty period, (b) Distributor has used its commercially reasonable best
efforts to replicate the circumstances surrounding the non-compliance and
provided Primus with such other information and materials to fix the non-
compliance as Primus has reasonably requested and (c) Primus is unable to
resolve or has not made substantial progress in its attempts to resolve the non-
compliance within sixty (60) days of receipt of such notice, then Primus shall
repay Distributor the license fees, support fees received by Primus and Upgrade
fees specified in Schedules 3 and 4, less a deduction (the "Performance Remedy
Deduction," as defined below) for any end-user license fees, support fees and/or
Upgrade fees that Distributor and/or its sub-distributors are not obligated to
refund to Authorized End-Users), and immediately terminate the Distribution
Term, in full and final satisfaction of all and any of Distributor's claims
arising out of media or Software failure, except for Primus' failure to meet its
obligations under Sections 11.4 and 12 of this Agreement. "Performance Remedy
Deduction" means an amount equal to the sum of (i) the product obtained by
multiplying [*] US Dollars (US $[*]) by the number of Authorized Workstations
licensed to Authorized End-Users and with respect to which the Initial Software
media and performance warranties afforded to such Authorized End-Users under
their respective Software License Agreements are no longer effective, (ii) [*]
percent ([*]%) of end-user support and maintenance fees that Distributor and/or
its sub-distributors are not obligated to refund to Authorized End-Users ("Non-
Refundable S&M Fees"), and (iii) the product obtained by multiplying [*] percent
([*]%) of Non-Refundable S&M Fees by a fraction, the numerator of which is $[*],
and the denominator of which is the license fee paid by sub-licensees under the
applicable Software License Agreement for the relevant Authorized Workstations.

4.  Infringement Remedy. Primus shall defend and indemnify Distributor against
    -------------------                                                       
any proceeding based upon any failure to satisfy the warranty set forth in
Paragraph 1.3 above, provided that (a) Distributor shall notify Primus in
writing of any claim of infringement promptly after it has been made, (b) Primus
shall have exclusive control over the defense and settlement of the proceeding,
(c) Distributor shall provide such

- ----------------------
[*] -- omitted, confidential material, which material has been separately filed 
with the Securities and Exchange Commission pursuant to a request for 
confidential treatment.

                                    Page 20
<PAGE>
 
assistance in defense of the proceeding as Primus may reasonably request,
at Primus' reasonable expense, and (d) Distributor shall comply with any
settlement or court order made in connection with the proceeding. In the event
that use of the Software becomes, or in Primus' reasonable opinion is likely to
become, the subject of a claim of infringement of any intellectual property
right of any third party, Primus shall have the right to: (i) procure the
continuing right of Distributor to use the Software; (ii) replace or modify the
Software in a functionally equivalent manner so that it no longer infringes; or
(iii) repay Distributor the license fees, support fees and Upgrade fees
specified in Schedules 3 and 4, less the Infringement Remedy Deduction (as
defined below), and immediately terminate this Agreement, in full and final
satisfaction of all and any of Distributor's claims arising out any infringement
claim, except for claims resulting from Primus' failure to meet its obligations
under Sections 11.4 and 12 of this Agreement. "Infringement Remedy Deduction"
means an amount equal to the sum of (i) the sum of all "Depreciated Amounts" (as
defined below), (ii) [*] percent ([*]%) of Non-Refundable S&M Fees, and (iii)
the product obtained by multiplying [*] percent ([*]%) of Non-Refundable S&M
Fees by a fraction, the numerator of which is $[*], and the denominator of which
is the license fee paid by sub-licensees under the applicable Software License
Agreement for the relevant Authorized Workstations. "Depreciated Amount" means,
with respect to each executed Software License Agreement, [*] US Dollars (US
$[*]) reduced by the same proportion applicable to any refund of the license
fees paid under such Software License Agreement, multiplied by the number of
Authorized Workstations licensed under such Software License Agreement.

5.  Warranties Repeated For Replacements and New Software.  The warranties and
    -----------------------------------------------------                     
other provisions of this Schedule 5 shall be automatically repeated for any
modifications of the Software delivered to remedy any non-compliance with the
warranties under Paragraphs 1.1 through 1.5 above, and for any New Software, in
each case upon shipment of the same to Distributor by Primus.

6.  Disclaimer Of Implied Warranties.  Primus makes no representation or
    --------------------------------                                    
warranty in connection with the Initial Software and New Software, except as set
forth in Paragraph 1 above.  EXCEPT AS SPECIFICALLY SET FORTH IN THIS SCHEDULE
5, PRIMUS DISCLAIMS AND DISTRIBUTOR WAIVES AND RELEASES ALL RIGHTS AND REMEDIES
OF DISTRIBUTOR, AND ALL WARRANTIES, OBLIGATIONS, AND LIABILITIES OF PRIMUS,
EXPRESS OR IMPLIED, ARISING BY LAW OR OTHERWISE, WITH RESPECT TO ANY BUG, ERROR,
OMISSION, DEFECT, DEFICIENCY, OR NONCONFORMITY IN ANY SOFTWARE OR OTHER ITEMS
FURNISHED UNDER THIS AGREEMENT, INCLUDING BUT NOT LIMITED TO ANY: (A) IMPLIED
WARRANTY OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE; (B) IMPLIED
WARRANTY ARISING FROM COURSE OF PERFORMANCE, COURSE OF DEALING, OR USAGE OF
TRADE; OR (C) CLAIM OF INFRINGEMENT.

                    Dispute Resolution And Other Provisions
                    ---------------------------------------

1. Dispute Resolution.
   ------------------ 
1.1 Governing Law; English Language to Apply. This Agreement shall be governed
by and interpreted in accordance with the internal laws of the State of
Washington, and, where such laws are preempted by the laws of the United States,
by the internal laws of the United States, in each case without regard to (a)
conflicts of laws principles and renvoi, and (b) the applicability, if any, of
the United Nations Convention on Contracts for the International Sale of Goods.
The governing language for this Agreement, for the transactions contemplated
hereby, for any notices, instruments or other documents or media transmitted or
delivered hereunder, and for the negotiation and/or resolution of any dispute or
other matter between the parties, shall be the English language. In the event of
any conflict between the provisions of any instrument, document, or other media
and an English version thereof, the provisions of the English version shall
prevail. Distributor hereby waives all and any rights it may have under any law
in the Exclusive Territory to have the Agreement written in any language other
than English. In transactions between the parties, a decimal point shall be
indicated by a period, and not by a comma. Notice periods shall be determined by
reference to the local time of the notice recipient.
1.2 Mediation. In the event of any controversy or claim arising out of or
relating to this Agreement or the breach or interpretation thereof, the parties
shall, upon not less than thirty (30) days notice from either one to the other,
submit themselves and the subject-matter of the dispute to mediation before an
independent mediator to be appointed by the Seattle office of the American
Arbitration Association or, if such office cannot do so, by the head office of
the American Arbitration Association. Costs of mediation shall be borne equally
between the parties.
1.3 Arbitration. In the event that the parties remain in dispute following the
mediation, the controversy or claim shall be determined by arbitration in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association by a single, disinterested arbitrator appointed in accordance with
such Rules. The determination of the arbitrator shall be final, conclusive and
binding. Judgment upon the award rendered may be entered in any court of any
state or country having jurisdiction.
1.4 Conduct. Each party shall ensure that any mediation and arbitration are
conducted as speedily as is reasonably possible, and that all and any
information disclosed during or in connection with the arbitration is treated by
each party with the strictest confidence.
1.5 Interim and Permanent Relief. Upon the application of either party to this
Agreement, and whether or not an arbitration or mediation has yet been
initiated, all courts having jurisdiction over one or more of the parties are
authorized to: (i) issue and enforce in any lawful manner such temporary
restraining orders, preliminary injunctions and other interim measures of relief
as may be necessary to prevent harm to a party's interests or as otherwise may
be appropriate pending the conclusion of arbitration proceedings pursuant to
this Agreement; and (ii) enter and enforce in any lawful manner such judgments
for permanent equitable relief as may be necessary to prevent harm to a party's
interests or as otherwise may be appropriate following the issuance of arbitral
awards pursuant to this Agreement.
1.6 Venue. Any mediation or arbitration conducted under or in connection with
this Agreement shall take place in Seattle, Washington at a time and location to
be determined by the mediator or arbitrator, as the case may be.
1.7 Legal Expenses. If any proceeding is brought by either party to enforce or
interpret any term or provision of this Agreement, the substantially prevailing
party in such proceeding shall be entitled to recover, in addition to all other
relief arising out of this Agreement, such party's reasonable attorneys' and
other experts' (including without limitation accountants) fees and expenses.
2. Exclusion of Certain Claims. IN NO EVENT SHALL EITHER PARTY BE LIABLE
   ---------------------------
(WHETHER IN TORT OR CONTRACT, UNDER STATUTE OR OTHERWISE) FOR ANY INDIRECT,
SPECIAL, PUNITIVE, CONSEQUENTIAL OR INCIDENTAL DAMAGES, INCLUDING WITHOUT
LIMITATION DAMAGES FOR LOSS OF PROFITS, BUSINESS INTERRUPTION, LOSS OF
INFORMATION AND THE LIKE, ARISING OUT OF ITS PERFORMANCE OR NONPERFORMANCE OF
THIS AGREEMENT OR THE USE, INABILITY TO USE OR RESULTS OF USE OF THE SOFTWARE,
EVEN IF THE OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
3. Limitation of Liability. Except with respect to Primus' obligations under
   -----------------------
paragraph 4 of Schedule 5 (Primus' infringement remedy) and for infringements by
Distributor and/or any of Distributor's sub-distributors of any of Primus'
intellectual property rights, neither Primus' nor Distributor's liability
(whether in tort or contract, under statute or otherwise) with regard to this
Agreement or any Software or other items furnished in connection with this
Agreement shall in any event exceed Two Million US Dollars (US $2,000,000).
4. Equitable Relief. Each of Distributor and Primus acknowledges that damages
   ----------------
will be an inadequate remedy if the other violates the terms of this Agreement
protecting the other's intellectual property rights. Accordingly, subject to
Section 1 of this Schedule, each of them shall have the right, in addition to
any other rights each of them may have, to obtain in any court of competent
jurisdiction, temporary, preliminary 

                                    Page 22
<PAGE>
 
and permanent injunctive relief to restrain any breach, threatened breach, or
otherwise to specifically enforce any of such terms.

     ---------------------
determines that the labeling of the tangible media matches the item descriptions

any court or other judicial tribunal order.  (See Section 8.5 below for notices 
of request orders.)

perpetual, and royalty-free license to sublicense the deposit materials to 
FlexSAFE Beneficiary upon the release, if any, of the deposit materials in

         Depositor with a copy of FlexSAFE Beneficiary's notice by certified 
         mail, return receipt requested, or by commercial express mail.  If
         Depositor provides DSI with  contrary instructions  within sixty (60)
         days, DSI shall not deliver a copy of the deposit materials to 
         FlexSAFE Beneficiary.

          order; and

      c.  Ensure that DSI not be required to deliver the original (as opposed to

                            FIRST RIGHT OF REFUSAL



  This Agreement dated this 26th day of September 1997 is between Primus
                            ----
Communications Corporation ("HQ") and Primus K.K. ("KK").

  It is the parties' intent to enter into a long term exclusive distribution
arrangement pursuant to which KK shall be the exclusive distributor of all Asian
language versions of HQ's products.  This first right of refusal is an interim
arrangement to provide KK with necessary assurances until such time as such
agreement has been entered into.


  With respect to the long-term distribution arrangement (but not the first
right of refusal that is the subject of this agreement) this letter is only an
expression of present intent and does not create or impose any binding legal
duties or obligations on either of KK or HQ.  This Agreement does not affect in
any way any rights or obligations which may or may not exist regarding such long
term distribution arrangement.


Now therefore, for good and valuable consideration, receipt of which is
acknowledged by the parties, the parties agree as follows:

  HQ hereby grants KK the first right of refusal as provided below.

  Prior to entering into any agreement with any person or entity for the
distribution of Asian language equivalents of HQ's products, HQ shall offer
substantially identical terms to KK.  HQ shall notify KK of such terms.  Such
notice shall contain all key terms of the proposed agreement.  KK shall treat
such notice and any related communications as confidential information under the
Non-Disclosure Agreement between KK and HQ.  If KK does not notify HQ that it
accepts such terms within thirty (30) days of such notice, then HQ shall be
permitted to enter into an agreement on such key terms and no other key terms
during the three (3) month period from the date of expiration of such notice.
Except as set forth above, and except for that certain Exclusive Distribution
License Agreement, dated of even date herewith, between HQ and Trans Cosmos,
Inc. ("TCI"), HQ shall not enter into any other agreements for distribution of
Asian language products, but may market and distribute such products directly.

  This first right of refusal shall terminate upon any of the following events:


1.   If any member of the KK Group (as defined below) challenges in any legal or
     arbitration proceeding the validity of the copyright, patents, trademarks,
     or trade secrets of HQ, then HQ may immediately terminate this right of
     first refusal by notice to KK.  "KK Group" means KK, TCI, Best Career
     Company ("Best") or any entity controlling, controlled by or under common
     control of TCI and/or Best.

                                       1
<PAGE>
 
2.   If any member of the KK Group commercially markets or distributes any
     product (a "KK Product") that is, or if marketed and distributed in the
     English language would be competitive with HQ's SolutionBuilder(R) and/or
     SolutionPublisher(R) software products, and if any marketing and
     distribution of the KK Product continues for a period in excess of thirty
     (30) days from notice from HQ to KK requesting that such marketing and
     distribution cease, then HQ may immediately terminate this First Right of
     Refusal by notice to KK.

3.   If TCI and/or Best transfers any of their interest in KK to a third party
     which is not a TCI Affiliate (as defined below), HQ may immediately
     terminate this right of first refusal by notice to KK. "TCI Affiliate"
     means any entity in which TCI owns equity possessing at least eighty
     percent (80%) of the total combined voting power of all classes of equity
     entitled to vote

  Any notice required or permitted to be given under this Agreement shall be
effective if it is in writing and sent prepaid by internationally recognized
private courier (e.g., DHL) and by fax, to the appropriate party hereto at the
address set forth below.  Either party may change its address for receipt of
notice by notice to the other party in accordance with this section.

                    Dispute Resolution And Other Provisions
                    ---------------------------------------

1.  Dispute Resolution.
    ------------------ 

1.1  Governing Law; English Language to Apply.  This Agreement shall be governed
by and interpreted in accordance with the internal laws of the State of
Washington, and, where such laws are preempted by the laws of the United States,
by the internal laws of the United States, in each case without regard to (a)
conflicts of laws principles and renvoi, and (b) the applicability, if any, of
the United Nations Convention on Contracts for the International Sale of Goods.
The governing language for this Agreement, for the transactions contemplated
hereby, for any notices, instruments or other documents or media transmitted or
delivered hereunder, and for the negotiation and/or resolution of any dispute or
other matter between the parties, shall be the English language.  In the event
of any conflict between the provisions of any instrument, document, or other
media and an English version thereof, the provisions of the English version
shall prevail.  KK hereby waives all and any rights it may have under any law to
have the Agreement written in any language other than English.  In transactions
between the parties, a decimal point shall be indicated by a period, and not by
a comma.  Notice periods shall be determined by reference to the local time of
the notice recipient.

1.2  Mediation.  In the event of any controversy or claim arising out of or
relating to this Agreement or the breach or interpretation thereof, the parties
shall, upon not less than thirty (30) days notice from either one to the other,
submit themselves and the subject-matter of the dispute to mediation before an
independent mediator to be appointed by the head office of the American
Arbitration Association.  Costs of mediation shall be borne equally between the
parties.

1.3  Arbitration.  In the event that the parties remain in dispute following the
mediation, the controversy or claim shall be determined by arbitration in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association by a single, disinterested arbitrator appointed in accordance with
such Rules.  The determination of the arbitrator shall be final, conclusive and
binding.  Judgment upon the award rendered may be entered in any court of any
state or country having jurisdiction.

1.4  Conduct.  Each party shall ensure that any mediation and arbitration are
conducted as speedily as is reasonably possible, and that all and any
information disclosed during or in connection with the arbitration is treated by
each party with the strictest confidence.

1.5  Interim and Permanent Relief.  Upon the application of either party to this
Agreement, and whether or not an arbitration or mediation has yet been
initiated, all courts having jurisdiction over one or more of the parties are
authorized to: (i) issue and enforce in any lawful manner such temporary
restraining orders, preliminary injunctions and other interim measures of relief
as may be necessary to prevent harm to a party's interests or as otherwise may
be appropriate pending the conclusion of arbitration proceedings pursuant to
this Agreement; and (ii) enter and enforce in any lawful manner such judgments
for permanent equitable relief as may be necessary to prevent harm to a party's
interests or as otherwise may be appropriate following the issuance of arbitral
awards pursuant to this Agreement.

1.6  Venue.  Any mediation or arbitration conducted under or in connection with
this Agreement shall take place in Seattle, Washington at a time and location to
be determined by the mediator or arbitrator, as the case may be.

1.7  Legal Expenses.  If any proceeding is brought by either party to enforce or
interpret any term or provision of this Agreement, the substantially prevailing
party in such proceeding shall be entitled to recover, in addition to all other
relief arising out of this Agreement, such party's reasonable attorneys' and
other experts' (including without limitation accountants) fees and expenses.

2.  Waiver.  No waiver of or with respect to any provision of this Agreement,
    ------                                                                   
nor consent by a party to the breach of or departure from any provision of this
Agreement, shall in any event be binding on or effective against such party
unless it be in writing and signed by such party, and then such waiver shall be
effective only in the specific instance and for the purpose for which given.

3.  Captions and Headings.  The captions and headings are inserted in this
    ---------------------                                                 
Agreement for convenience only, and shall not be deemed to limit or describe the
scope or intent of any provision of this Agreement.

4.  Severability; Invalidity.  If any provision of this Agreement is held to be
    ------------------------                                                   
invalid, such invalidity shall not render invalid the remainder of this
Agreement or the remainder of which such invalid provision is a part.  If any
provision of this Agreement is so broad as to be held unenforceable, such
provision shall be interpreted to be only so broad as is enforceable.

5.  Assignment.  KK shall not assign any of its rights under this Agreement
    ----------                                                             
without the prior written consent of Primus, which shall not be unreasonably
withheld. Subject to the foregoing restriction on assignment by KK, this
Agreement shall be binding upon, inure to the benefit of and be enforceable by
the parties and their respective successors and assigns.

6.  Entire Agreement; Amendments.  This Agreement constitutes and embodies the
    ----------------------------                                              
entire agreement and understanding between the parties with respect to the
subject matter hereof and supersedes all prior or contemporaneous written,
electronic or oral

                                       1

communications, agreements or understandings between the parties with respect
thereto. This Agreement may not be modified or amended except by a written
instrument executed by the parties. In the event of any conflict between the
provisions of this Agreement and the terms of any form of purchase order or
invoice, the provisions of this Agreement shall prevail.

Primus' reasonable expense, Distributor shall execute all such written
agreements and instruments, and take all such other action as may be necessary

Distributors without obtaining Primus' prior written approval (not to be
unreasonably withheld). Distributor's request for approval shall contain, at a
minimum: (a) the name and a description of the proposed Sub-Distributor; and (b)
an accurate English translation of the proposed Sub-Distribution Agreement,

the Software, the Documentation and Primus' Confidential Information constitute
trade secrets and are the valuable property of Primus and its licensors, and

for Primus Maintenance. For purposes of determining the minimum fees, the Gross
Maintenance Revenue Realized by Distributor during the relevant quarter shall be
deemed to be [*] percent ([*]%) of the Distributor's Resale Price for the
Software with respect to which Distributor Realizes Gross Software Revenue
during the quarter.

7.3  Provisions Relating to Gross Revenue.  For the purposes of this Section 7,
     ------------------------------------                                      
"Gross Revenue" means Gross Software Revenue and Gross Maintenance Revenue.

applicable License Agreement or Support and Maintenance Agreement by an End-User
(or any amendment thereto).

     7.3.2 Gross Revenue from Bundled or Promotional Transactions. The Gross
Revenue in a unit-priced transaction (e.g., bundled transactions, discount or
promotional offers, and the like) involving both (i) the Software or End User
Maintenance (or both), and (ii) one or more other products or services provided
by Distributor, will be the greater of: (i)  Distributor's stand-alone price
associated with the Software or the End User Maintenance in transactions
involving the Software or End User Maintenance alone; and (ii) the actual
revenue realized by Distributor in the unit-priced transaction, prorated between
the Software or End User Maintenance (or both) and such other products and
services in accordance with their respective stand-alone prices.

     7.3.3 Exclusions from Gross Revenue.  Gross Revenue does not include (i)

maintenance of separately identified and priced software that is developed,
licensed, or otherwise acquired by Distributor which Distributor may combine for
distribution purposes with all or part of the Software; or (ii) amounts received
by Distributor that are attributable to separately itemized and billed shipping
costs and insurance or to sales taxes or similar taxes.

7.4  No Charge for Internal Use and Evaluations. Distributor shall not be
     ------------------------------------------                          
required to pay Primus Software royalties or fees for Primus Maintenance with
respect to: (i) Software that Distributor uses internally pursuant to the
internal use license granted under Section 2.2.4; and (ii) Software used by
Evaluators; provided always, however, that Distributor does not permit any
evaluation to extend beyond thirty (30) days without Primus' prior written
consent, not to be unreasonably withheld.

     ------                                                                     
a transaction involving an End-User whose head office is located outside the
Territory, or if Licensee sub-licenses any Software outside the Territory as
part of a transaction involving an End User whose head office is located within
the Territory, then Primus and Licensee shall split equally between them the
Software license fees and support and maintenance fees payable by the End User.
In the event of any multiple-territory transaction where Distributor and Primus'
other distributors, agents or representatives cannot mutually resolve their
respective shares in the compensation arising from the customer order, then
Primus may, in its sole and absolute discretion, allocate the Software license
fees, End User Maintenance fees, and the responsibility for providing End User
Maintenance among them (less, in the case of Distributor, any compensation
payable to Primus under this Agreement).

7.4  Referrals. If a customer in the Territory prefers to sub-license Software
     ---------                                                                
or purchase services directly from Primus for use in the Territory, and if
Distributor's appointment with respect to such Software is non-exclusive, then
Distributor shall refer the customer to Primus. If the customer sub-licenses
Software from Primus as a direct result of Distributor's activities, and within
six (6) months of Distributor's last substantial contact with the customer
concerning the Software, then Primus shall pay Distributor a referral fee equal
to the "Referral Percentage" of the software license fees recognized in
accordance with US generally accepted accounting principles by Primus from such
customer in the first year of the sub-license term. "Referral Percentage" means
the percentage amount specified in Table E.

contains a list of Software license and End User Maintenance fees recommended by
Primus for use by Distributor in distributing the Software and providing End
User Maintenance in the Territory. If Distributor wishes to sub-license Software
or provide End User Maintenance at less than the Applicable List Price, or if
Distributor wants to provide any Person with an option to acquire rights to the
Software or End User Maintenance at less than the Applicable List Price, then
Distributor shall first provide Primus with not less than five (5) business days
prior written notice. Notwithstanding any of the foregoing, Distributor shall be
under no obligation to sub-license the Software or provide End User Maintenance
to End Users at the Applicable List Price, but may price the Software and End
User Maintenance in its reasonable discretion.

7.6  Payment Terms. Unless another date is specified in this Agreement, all
     -------------                                                         
payments by Distributor to Primus shall be due within thirty (30) days of the
date of Primus' invoice. Distributor shall make all payments in United States
currency, in readily available funds. Overdue payments shall accrue interest at
the lesser of US prime rate on the date of the invoice plus five percent (5%)

solely responsible for any applicable sales, use, or any value added or similar
taxes (collectively, "Sales Taxes") payable under, or arising out of or in
connection with this Agreement, other than taxes imposed in the United States
based upon Primus' income. Any prices, fee schedules or invoices provided by
Primus are exclusive of any Sales Taxes, unless specifically stated otherwise.
Upon request by Primus, Distributor shall promptly furnish Primus with copies of
tax receipts and other documents evidencing the withholding and payment of any
local taxes applicable to Primus, so that Primus may file for a tax credit.
Distributor shall cooperate with Primus in taking all such steps and filing all
such documents as Primus reasonably requests to minimize any such withholding.

Trademarks by Distributor or any Sub-Distributor shall inure solely to the
benefit of Primus.

8.3  No Infringement. Distributor shall not at any time adopt, use or register
     ---------------

                              Terms and Conditions

Section 1.  Definitions.

1.1      "Confidential Information" means any and all information disclosed by
Owner that is identified as "confidential" or "proprietary," either by legend on
written or electronically stored material, or in advance if disclosed verbally.
Confidential Information includes, without limitation, research and development,
know-how, inventions, trade secrets, software, and market analysis, research,
strategies, projections and forecasts. Confidential Information also includes,
without limitation, information disclosed by Owner with permission from a third
party, and combinations of or with publicly known information where the nature
of the combination is not publicly known.

1.1.1    Exceptions.  Confidential Information does not include information
which:
(a)  was publicly known at the time of Owner's communication thereof to
     Recipient, or which subsequently becomes publicly known through no fault of
     Recipient;
(b)  was in the possession of Recipient prior to its being communicated to
     Recipient by Owner;
(c)  becomes available to Recipient on a non-confidential basis from a source
     other than Owner, provided that such source is not bound by any obligation
     of confidentiality to Owner with respect to such information; or
(d)  was independently developed by Recipient without reference to the
     Confidential Information communicated by Owner.

Section 2.  Covenant Not to Disclose.

Recipient shall not use Owner's Confidential Information except for purposes of
evaluating, maintaining and furthering a business relationship with Owner.
Recipient shall maintain in confidence the Confidential Information received
from Owner and shall not directly or indirectly disclose such information to any
person or entity except Recipient's employees and consultants, and then only on
a need-to-know basis.  Recipient shall ensure that such employees and
consultants are bound by a written agreement to protect the received
Confidential Information from unauthorized use and disclosure.  Recipient shall
protect Owner's Confidential Information from disclosure to others using the
same degree of care that it uses to protect its own most highly confidential
information, but in no event less than a reasonable standard of care.  Recipient
shall not make or distribute any more copies or summaries of Owner's
Confidential Information than are necessary to evaluate, maintain and further a
business relationship between the Parties, and shall ensure that all such copies
or summaries are marked as confidential and the property of Owner.

Section 3.  No Obligation Of Disclosure.

Neither Party shall have any obligation to disclose its Confidential Information
to the other. Either Party may, at any time, cease providing its Confidential
Information to the other Party, and may require the return of Confidential
Information previously disclosed by written notice.

Section 4.  Disclosure Required By Law.

If any applicable law, regulation or court order requires Recipient to disclose
any of Owner's Confidential Information, Recipient shall promptly notify Owner
in writing prior to making any such disclosure, in order to facilitate Owner's
efforts to protect its Confidential Information.  In such circumstances,
Recipient shall cooperate with 

                                 Page 12 of 34
<PAGE>
 
Owner, at Owner's reasonable expense, in seeking and obtaining protection for
Owner's Confidential Information.

Section 5.  Title.

Owner shall retain all ownership rights in and to the Confidential Information
it discloses to Recipient.  No licenses or rights under any patent, trademark,
copyright, trade secret or other intellectual property right shall be granted or
implied under this Agreement.  Neither Party shall be obligated under this
Agreement to acquire from or provide to the other Party any service or product.

Section 6.  Termination.

Either Party may terminate this Agreement at any time without cause upon written
notice to the other party. All obligations of confidentiality shall survive such
termination. Upon termination of this Agreement, Recipient shall promptly return
all of Owner's Confidential Information provided to it in tangible form,
together with any and all copies and/or summaries, and shall destroy all of
Owner's Confidential Information that is electronically stored; provided,
however, that each Party's legal department may retain one copy of the
Confidential Information in its file solely for the purpose of identifying
information designated as "Confidential Information."

Section 7.  Specific Performance.

The Parties acknowledge that Confidential Information is unique and valuable,
and that Owner will have no adequate remedy at law if Recipient does not comply
with its obligations under this Agreement.  Therefore, Owner shall have the
right, in addition to any other rights it may have, to obtain in any court of
competent jurisdiction temporary, preliminary and permanent injunctive relief to
restrain any breach, threatened breach, or otherwise to specifically enforce any
obligations of Recipient if Recipient fails to perform any of its obligations
under this Agreement.

Section 8.  Miscellaneous.

8.1.     Dispute Resolution.

8.1.1    Governing Law.  This Agreement shall be governed by and interpreted in
accordance with the internal laws of the State of Washington, and, where such
laws are preempted by the laws of the United States, by the internal laws of the
United States, in each case without regard to conflicts of laws principles.

8.1.2    Arbitration.  In the event of any controversy or claim arising out of
or relating to this Agreement or the breach or interpretation thereof, the
parties shall, upon five days notice from either one to the other, submit
themselves and the subject-matter of the dispute to arbitration in accordance
with the Commercial Arbitration Rules of the American Arbitration Association by
a single, disinterested arbitrator appointed in accordance with such Rules.  The
determination of the arbitrator shall be final, conclusive and binding.
Judgment upon the award rendered may be entered in any court of any state or
country having jurisdiction. Each party shall ensure that any arbitration is
conducted as speedily as is reasonably possible, and that all and any
information disclosed during or in connection with the arbitration is treated by
each party with the strictest confidence. Any arbitration conducted under or in
connection with this Agreement shall take place in Seattle, Washington at a time
and location to be determined by the arbitrator.

8.1.3    Interim and Permanent Relief.  Upon the application of either party to
this Agreement, and whether or not an arbitration has yet been initiated, all
courts having jurisdiction over one or more of the parties are authorized to:
(i) issue and enforce in any lawful manner such temporary restraining orders,
preliminary injunctions and other interim measures of relief as may be necessary
to prevent harm to a party's interests or as otherwise may be appropriate
pending the conclusion of arbitration proceedings pursuant to this Agreement;
and (ii) enter and enforce in any lawful manner such judgments for permanent
equitable relief as may be necessary to prevent harm to a party's interests or
as otherwise may be appropriate following the issuance of arbitral awards
pursuant to this Agreement.

8.1.4    Legal Expenses.  If any proceeding is brought by either party to
enforce or interpret any provision of this Agreement, the substantially
prevailing party in such proceeding shall be entitled to recover, in addition to
all other relief arising out of this Agreement, such party's reasonable
attorneys' and other experts' fees and expenses.

8.2      Waiver; Severability; Invalidity.  No waiver of or with respect to any
provision of this Agreement, nor consent by a party to the breach of or
departure from any provision of this Agreement, shall in any event be binding on
or effective against such party unless it be in writing and signed by such
party, and then such waiver shall be effective only in the specific instance and
for the purpose for which given.  If any provision of this Agreement is held to
be invalid, such invalidity shall not render invalid the remainder of this
Agreement or the remainder of which such invalid provision is a part.  If any
provision of this Agreement is so broad as to be held unenforceable, such
provision shall be interpreted to be only so broad as is enforceable.

8.3      Notices.  Any notice or other communication under this Agreement given
by either party to the other party shall be deemed to be properly given if given
in writing and delivered (i) by nationally recognized private courier (e.g.,
Federal Express) or (ii) by mail (return receipt requested), properly addressed
and stamped with the required postage, to the recipient at the address
identified in its signature block to this Agreement.  Either party may from time
to time change its address by giving the other party notice of the change in
accordance with this Section.

8.4      Entire Agreement; Amendments.  This Agreement constitutes and embodies
the entire agreement and understanding between the parties with respect to the
subject matter hereof and supersedes all prior or contemporaneous written,
electronic or oral communications, agreements or understandings between the
parties with respect thereto.  This Agreement may not be modified or amended
except by a written instrument executed by the parties.

Primus' generic content standard and process documents as necessary to meet
Licensee's internal training needs, provided however, that Primus shall retain
and Licensee hereby assigns to Primus all and any ownership rights in and to all
such modifications, and provided further, that such modifications shall be
deemed to be Documentation under this Agreement, to the effect that Licensee has
the same rights to use the modifications as apply to the rest of the

with respect to such Software.

Section 4.  Compensation; Additional Purchases.

4.1  Payment of License Fee. Licensee shall pay Primus KK the Software license
fees in cash in the amounts and on the dates specified in Tables A and B. Unless
Licensee's accounting policies permit Licensee to pay such fees in the absence
of a purchase order, Licensee shall issue an appropriate purchase order with
respect to such fees immediately following execution of this Agreement by
Licensee. Payment is due as specified in Table B, irrespective of whether
Licensee has issued a purchase order. Primus KK may impose a finance charge of
1% per month on amounts unpaid by Licensee on their due date.

4.2  Additional License Rights. If Licensee wishes to increase the number of
Authorized Workstations, Authorized Users or Fee Based Servers, then Licensee
shall submit a purchase order to Primus KK for the quantity of additional
Authorized Workstations, Authorized Users and Fee-Based Servers desired at the
rates and in the minimum blocks for increasing licensed usage specified in
Schedule 3 (if any). Under no circumstances shall any of such rights extend
beyond the period in which Distributor has the right to distribute the Software.
If no rate or minimum is specified, then Primus KK and Licensee shall negotiate
in good faith to determine a mutually satisfactory rate and minimum license
amount, and shall both execute an amendment to this Agreement reflecting such
terms in supplemental Tables A and B (numbered A-1, A-2 and so forth). Upon
execution of the amendment, Licensee may (i) install the Server Software on the
additional Fee-Based Servers; (ii) install the Client Software on the additional
Authorized Workstations; and (iii) increase the number of Authorized Users
accordingly. If Licensee increases the number of Fee-Based Servers, then
Licensee shall also notify Primus KK of (a) the model, serial number and ID of
the server on which the Server Software is to be installed, and its IP address,
host ID and/or disk ID, and (b) the location of the Licensed Site.

4.3  Sales Taxes, Etc. Licensee shall be responsible for any applicable sales,
use, or any value added or similar taxes payable with respect to the licensing
of the Software to Licensee, or arising out of or in connection with this
Agreement, other than taxes imposed in Japan based upon Primus KK's income. If
Licensee has tax-exempt status, Licensee shall provide written evidence of such
status with its purchase orders.

4.4  Accounting. Licensee shall keep current, complete and accurate records
regarding the location, model name, and serial number of all Authorized Servers
on which the Server Software is installed, of all 

                                 Page 16 of 34
<PAGE>
 
installations of the Client Software made by Licensee and any Authorized User,
of all personal user IDs and linked passwords issued with respect to applicable
Software, and of the number of concurrent users of applicable Software. Licensee
shall provide such information to Primus KK within five (5) days of Primus KK's
written request. Upon five (5) days prior written notice, Primus KK and/or its
representatives may inspect, audit, and copy such records of Licensee and access
the Server Software at any of Licensee's relevant locations and/or Licensed
Sites, at any time during Licensee's regular business hours. Unless an audit
discloses a material discrepancy in Licensee's favor, Primus KK may exercise
such audit rights no more than once during any twelve (12) month period. In the
event of any understatement of the license fees due, Licensee shall promptly pay
such fees based upon Primus KK's then current list price and, upon receipt of
such fees, Primus KK will extend this License to correct any such deficiency.
Primus KK's acceptance of any payment shall be without prejudice to any other
rights or remedies of Primus KK under this Agreement or applicable law. Upon
written request by Primus KK, Licensee shall transmit a current, complete and
correct copy of the log file for each copy of the Server Software to Primus KK;
provided, however, that Primus KK may not request a copy of the log file more
frequently than once a quarter, unless review of a log file has indicated
additional fees are due to Primus KK.

Section 5.  Additional Rights And Obligations.

5.1   Increase in Application Servers. Licensee may increase the number of
Application Servers at no charge. If Licensee wishes to increase the number of
Application Servers, then Licensee shall provide Primus KK with written notice

written agreement between them, disclose or otherwise make known or available to
any person or entity, or use for Recipient's own account, any of Discloser's
Confidential Information. Recipient shall use all reasonable procedures to
safeguard Discloser's Confidential Information.

KK of any unauthorized use of any Software of which Licensee becomes aware. In
the event of any unauthorized use by any Authorized User (or by any employee,
agent, representative or contractor of Licensee or of any Authorized User),
Licensee shall use its best efforts to immediately terminate and prevent further
occurrences of such unauthorized use. If Licensee commences any legal proceeding
in connection with such unauthorized use, then Primus KK and Primus may, at
Primus KK's or Primus' option and expense, participate in or control any such
proceeding. In such event, Licensee, Primus KK and Primus shall each provide the
other with such authority, information and assistance related to such proceeding
as may be reasonably necessary to safeguard Primus KK's and Primus' interests

existing under the laws of Japan.

6.2  Upstream Supplier Software Warranties. Primus KK warrants to Licensee that
the Upstream Supplier Software, as delivered by Primus KK to Licensee, will

which Primus KK is a party or by which it is bound.

6.4  Bugs and Abatement. Without limiting the foregoing, Primus KK does not
warrant that the Software is free from all bugs, errors, or omissions. The
warranties in this Section 6.1 shall automatically abate to the extent that the

                                 Page 17 of 34
<PAGE>
 
receipt of such written notice from Licensee then, except as otherwise specified

terminate the License with respect to such Software, and (ii), with respect to
non-compliant New Software, promptly refund all of the most recent annual
Support and Maintenance Agreement fees paid by Licensee and attributable to the
development of such New Software, in each case (i) and (ii) in full and final
satisfaction of all and any of Licensee's claims arising out of media or
Software failure.

6.6  Infringement Remedy. Primus KK shall defend and indemnify Licensee against
any proceeding based upon any failure to satisfy the warranties set forth in

proceeding as Primus KK or Primus KK's licensors may reasonably request, at
Primus KK's reasonable expense, and (e) Licensee shall comply with any court
order or settlement made in connection with the proceeding. If use of the
Software is, or in Primus KK's reasonable opinion is likely to become, the
subject of a claim of infringement of any intellectual property right of any
third party, then Primus KK shall have the right to: (i) procure the continuing
right of Licensee to use the Software; (ii) replace or modify the Software in a
functionally equivalent manner so that it no longer infringes; or (iii) except
as otherwise specified in Schedule 2, terminate the License with respect to the
Software subject to the infringement claim and refund to Licensee an amount
equal to the depreciated License fees paid by Licensee for such Software
(calculated on a straight line basis over a five (5) year life).

6.7  Warranties Repeated For Replacements and New Software. The warranties and
other provisions of this Section 6 shall be automatically repeated for any

warranties under Sections 6.1 and 6.2 and for any New Software, in each case
upon shipment of the same by Primus KK to Licensee.

6.6  Disclaimer Of Implied Warranties. Primus KK makes no representation or
warranty in connection with the Software, except as set forth in Sections 6.1,
6.2 and 6.3. EXCEPT AS SPECIFICALLY SET FORTH IN THIS SECTION 6, AND TO THE
MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, PRIMUS KK DISCLAIMS, FOR ITSELF AND
FOR PRIMUS, AND LICENSEE WAIVES AND RELEASES ALL RIGHTS AND REMEDIES OF
LICENSEE, AND ALL WARRANTIES, OBLIGATIONS, AND LIABILITIES OF [DISTRIBUTOR] OR

authorized to: (i) issue and enforce in any lawful manner such temporary
restraining orders, preliminary injunctions and other interim measures of relief
as may be necessary to prevent harm to a party's interests or as otherwise may
be appropriate pending the conclusion of arbitration proceedings pursuant to
this Agreement; and (ii) enter and enforce in any lawful manner such judgments
for permanent equitable relief as may be necessary to prevent harm to a party's
interests or as otherwise may be appropriate following the issuance of arbitral
awards pursuant to this Agreement.

this Agreement shall take place at the location of party against whom the
proceeding is brought, at a time to be determined by the mediator or arbitrator,
as the case may be.

discretion) shall be entitled to recover, in addition to all other relief
arising out of this Agreement, such party's reasonable attorneys' and other
experts' (including without limitation accountants) fees and expenses (as
determined by the arbitrator in its sole discretion.

adversely restricted by reason of any circumstances beyond the reasonable
control and without the fault or negligence of the party affected, then the
party affected, upon giving prompt written notice to the other party, shall be
excused from such performance on a day-to-day basis to the extent of such
restriction (and the other party shall likewise be excused from performance of
its obligations on a day-to-day basis to the extent such party's obligations
relate to the performance so restricted); provided, however, that the party so
affected shall use all commercially reasonable efforts to avoid or remove such
causes of non-performance and both parties shall proceed whenever such causes
are removed or cease.

Agreement for convenience only, and shall not be deemed to limit or describe the
scope or intent of any provision of this Agreement.

8.  Severability; Invalidity. If any provision of this Agreement is held to be
invalid, such invalidity shall not render invalid the remainder of this
Agreement or the remainder of which such invalid provision is a part. If any
provision of this Agreement is so broad as to be held unenforceable, such
provision shall be interpreted to be only so broad as is enforceable.

9.  Assignment. Licensee shall not assign any of its rights under this Agreement
without the prior written consent of Primus KK, which shall not be unreasonably
withheld. Distributor May assign all or any of its rights and obligations under
this Agreement to Primus upon expiration or termination of Distributor's rights

subject matter hereof and supersedes all prior or contemporaneous written,
electronic or oral communications, representations, agreements or understandings
between the parties with respect thereto. This Agreement may not be modified or
amended except by a written instrument executed by both parties. In the event of

Section 2.  Primus KK's Provision of Services.

2.1  Technical Support. Primus KK shall provide telephone, fax and electronic
support from its Seattle headquarters regarding use of the Software and
resolution of Errors Monday through Friday from 6.30 a.m. to 5:30 p.m. Tokyo
time. In addition, Primus KK shall make on-call technical support staff
available for High Priority situations (as 

                                 Page 21 of 34
<PAGE>
 
defined in Section 2.2.1 below) twenty-four (24) hours a day, seven (7) days a
week. Primus KK shall provide such support to up to two (2) support contacts
designated by Licensee who shall be knowledgeable in all aspects of Licensee's
operating environment. Primus KK shall use all commercially reasonable efforts
to ensure that a technical support representative returns Licensee's call within
one hour of receiving Licensee's notification of a High Priority situation
(described below).

2.2  Support Response. Primus KK will assign all Licensee requests for Error
support one of three response priorities. The priorities will dictate the timing
and nature of the response as follows:

2.2.1  High Priority. A major feature/function of the Software is not working or
the system integrity is at risk.

   Response Goal: Primus KK shall use all commercially reasonable efforts to
provide a Fix or Workaround within twenty-four (24) hours of Licensee's report
of the problem. If Primus KK cannot provide the Fix or Workaround within the
twenty-four (24) hours Primus KK will dedicate resources to the problem
resolution and will inform Licensee on a daily basis of the resolution status.

2.2.2  Medium Priority. Licensee's work flow is inhibited or a non-major
feature/function of the Software is not working.

   Response Goal: Primus KK shall use all commercially reasonable efforts to
provide a Fix or Workaround within two (2) business days of the Licensee's
report of the problem. If Primus KK cannot resolve the problem within the two
(2) business days, Primus KK will inform Licensee on a weekly basis of the
resolution status.

2.2.3  Low Priority. Licensee has a problem which is not seriously impacting
Licensee's workflow.

   Response Goal: Primus KK shall use all commercially reasonable efforts to
provide a Fix or a Workaround within five (5) business days of Licensee's report
of the problem. If Primus KK cannot resolve the problem within the five (5)
business days, Primus KK will provide Licensee with a status evaluation
regarding the ultimate resolution.

2.2.4  On-Site Visits. If Primus KK and Licensee mutually determine that Primus
KK may more effectively resolve a High Priority Error with an on-site visit to
Licensee's relevant location, then Licensee shall be responsible for Primus KK's
reasonable travel and living expenses incurred in conducting such visit. If
Licensee requests Primus KK to attend on-site for any other purpose, and Primus
KK agrees, then Licensee shall pay Primus KK for Primus KK's services on a time
and materials basis, at Primus KK's then current daily rates, and shall
reimburse Primus KK for Primus KK's reasonable travel and living expenses.

2.3  Licensee Cooperation. Licensee acknowledges that Primus KK may not be able
to resolve an Error if Licensee does not use all commercially reasonable efforts
to cooperate with and assist Primus KK in resolving the Error (including,
without limitation, in replicating the Error, in retrieving workstation, server
and log file data relating to the Error, and in providing Primus KK with remote
access to Licensee's installation for support purposes).

2.4  Upgrades. Primus KK shall provide Licensee with Upgrades as and when they
are made generally commercially available by Primus KK to Primus KK's customers.
Primus KK may provide Licensee with Maintenance Releases if Licensee is
experiencing, or in Primus KK's sole discretion may experience a High Priority
situation. As specified in the License Agreement, Upgrades shall constitute
"Software" under the License Agreement.

2.5  Scope of Support and Upgrade Services. Primus KK shall have no obligation
to correct Errors or support queries arising from Licensee's misuse or
alteration of the Software, failure or fluctuation of electrical power,
maintenance of the Software by anyone other than Primus KK or Primus KK's
authorized representatives, or Licensee's combining or merging Software with any
hardware or software not identified as compatible by Primus KK. Primus KK shall
have no obligation to correct Errors or support Licensed Programs except with
respect to the then current and next last current Major Releases; provided,
however, that for the purposes of determining the next last current Major
Release, Primus KK shall ignore any version of any Licensed Program that does
not comply with the media or performance warranties under the License Agreement.
It shall be a condition to Primus KK's provision of support services and
Upgrades pursuant to this Agreement that Licensee shall be current on its
support and maintenance fee payments for all of the Software.

Section 3.  Fees

3.1  Annual Fee. Licensee shall pay the initial annual support and maintenance
fee in cash in the amounts and on the dates set forth in Table A. Licensee shall
pay subsequent annual support and maintenance fees within thirty (30) days of

respect to such fees within twenty (20) days of the commencement of each
successive Support and Maintenance Term.

3.2  Notice of Change in Annual Fee. At least sixty (60) days before the end of

invoice. Primus KK may impose a finance charge of one percent (1%) per month on
amounts not paid within thirty (30) days of their applicable due date.

Tables A are exclusive of taxes unless expressly specified.

3.5  Additional License Rights. In the event that Licensee acquires rights under
the License Agreement to additional Authorized Workstations or Authorized Users
("Additional Seats"), Primus KK and Licensee shall both execute an amendment to
this Agreement reflecting the increase in a supplemental Table A (numbered A-1,
A-2 and so forth).

3.6  Support and Maintenance on Additional Seats. Licensee shall pay one
calendar year's support and maintenance fees on the Additional Seats at a rate
to be agreed with Primus KK (the "Agreed Rate"). Licensee shall make such

                                 Page 22 of 34
<PAGE>
 
Additional Seats. The then current Support and Maintenance Term shall be
automatically extended to the next anniversary of the effective date of the
applicable amendment. On or before the date on which the superceded Support and
Maintenance Term would have expired, Licensee shall pay Primus KK support and
maintenance fees at the Agreed Rate on a pro-rated basis through the end of the
Support and Maintenance Term then in effect, on all Authorized Workstations
and/or Authorized Users other than the Additional Seats.

USAGE OF TRADE.

Section 5.  Term and Termination

5.1  Term. The initial Support and Maintenance Term shall begin on the Effective
Date and shall end on its first anniversary.

5.2  Renewal. Notwithstanding the provisions of Section 5.1, this Agreement
shall be automatically renewed for a succeeding Support and Maintenance Term at
the end of each Support and Maintenance Term, unless Licensee provides Primus KK
with not less than thirty (30) days prior written notice before the end of the
expiring term of Licensee's decision to not renew this Agreement. Renewals shall
be deemed to include any rate increase of which Primus KK has notified Licensee
in accordance with Section 3.2 above.

5.3  Termination. This Agreement will terminate: 1) upon the expiration or
termination of the License Agreement; 2) upon the expiration of the then current
Support and Maintenance Term and timely receipt by Primus KK of Licensee's

discretion, upon failure of Licensee to pay support and maintenance fees when
due.

by either party where no other remedy is specified, the non-breaching party may
terminate this Agreement by giving the breaching party written notice of the
breach and the non-breaching party's intention to terminate. This Agreement

effective only in the specific instance and for the purpose for which given.

8.3  Severability; Invalidity.  If any provision of this Agreement is held to
be invalid, such invalidity shall not render invalid the remainder of this

provision shall be interpreted to be only so broad as is enforceable.

                              Secondline Support
                                        
Section 1.  Definitions.

For the purposes of this Schedule, the following capitalized words and phrases
shall be ascribed the following meanings:

1.1  "Error" means the failure of any Software program to conform in any
      -----                                                             
material respect to its published Documentation.

1.2  "Fix" shall mean a modification or an addition to a Software program or its
      ---

      ----------                                                          
circumvent or mitigate the impact of an Error, notwithstanding that the Error
still exists. Primus may provide a Workaround in lieu of a Fix in Primus' sole
discretion.

1.4  Other Defined Terms.  Other capitalized words and phrases shall have the
     -------------------                                                     
meanings ascribed to them in Section 1 of the Software Marketing and
Distribution Agreement of which this Schedule is part.

Section 2.  Primus' Provision of Secondline Support.
2.1  Technical Support. Primus shall provide telephone, fax and electronic
     -----------------                                                    
support to Distributor from its Seattle office regarding use of the Software and
resolution of Errors Monday through Friday from 6.30 a.m. to 5:30 p.m. local
time at such office. In addition, Primus shall make on-call technical support
staff available for High Priority situations (as defined in Section 2.2.1 below)
twenty-four (24) hours a day, seven (7) days a week. Primus shall provide such
support to up to two (2) support contacts designated by Distributor who shall be
knowledgeable in all aspects of Distributor's and End Users' operating
environments.

2.2  Support Response. Primus will assign all Distributor requests for Error
     ----------------                                                       
support one of three response priorities. The priorities will dictate the timing
and nature of the response as follows:

  2.2.1  High Priority. A major feature/function of the Software is not working
or the system integrity is at risk.

  Response Goal: Primus shall use all commercially reasonable efforts to provide
a Fix or Workaround to Distributor within  forty eight (48) hours of
Distributor's report of the problem. If Primus cannot provide the Fix or
Workaround within the forty-eight (48) hours Primus will dedicate resources to
the problem resolution and will inform Distributor on a daily basis of the
resolution status.

  2.2.2  Medium Priority. An End User's work flow is inhibited or a non-major
feature/function of the Software is not working.

  Response Goal: Primus shall use all commercially reasonable efforts to provide
a Fix or Workaround to Distributor within four (4) business days of the
Distributor's report of the problem. If Primus cannot resolve the problem within
the four (4) business days, Primus will inform Distributor on a weekly basis of
the resolution status.

  2.2.3  Low Priority. An End User has a problem which is not seriously
impacting Distributor's workflow.

  Response Goal: Primus shall use all commercially reasonable efforts to provide
a Fix or a Workaround to Distributor within seven (7) business days of
Distributor's report of the problem. If Primus cannot resolve the problem within
the seven (7) business days, Primus will provide Distributor with a status
evaluation regarding the ultimate resolution.

2.3  On-Site Visits. If Primus and Distributor mutually determine that Primus
     --------------                                                          
may more effectively resolve a High Priority Error with an on-site visit to
Distributor's or the End User's relevant location, then Distributor shall be
responsible for Primus' reasonable travel and living expenses incurred in
conducting such visit. If Distributor requests Primus to attend on-site for any
other purpose, and Primus agrees, then Distributor shall pay Primus for Primus'
services on a time and materials basis, at Primus' then current daily rates for
the Territory, and shall reimburse Primus for Primus' reasonable travel and
living expenses.

2.4  Access to Primus' Knowledgebase.  To the extent reasonably determined
     -------------------------------                                      
necessary by Primus, Primus shall provide Distributor with access to Primus'
knowledgebase of solutions to Software Errors. Distributor shall comply with
Primus' reasonable security precautions related to such access, and shall treat
all knowledgebase information as Confidential Information of Primus; provided,
however, that Distributor may disclose Error solutions to End Users as part of
its End User Maintenance obligations, but only as confidential information under
an effective non-disclosure agreement between Distributor and the End User.

2.5  Distributor Cooperation. Distributor acknowledges that Primus may not be
     -----------------------                                                 
able to resolve an Error if Distributor and any affected End User do not use all
commercially reasonable efforts to cooperate with and assist Primus in resolving
the Error (including, without limitation, in replicating the Error, in
retrieving workstation, server and log file data relating to the Error, and in
providing Primus with remote access to Distributor's or the End User's
installation for support purposes).

2.6  Scope of Secondline Support Services. Primus shall have no obligation to
     ------------------------------------                                    
correct Errors or support queries arising from any misuse or alteration of the
Software by any Person other than Primus, failure or fluctuation of electrical
power, maintenance of the Software by anyone other than Primus or Primus'
authorized representatives, or the combination or merging of the Software by any
Person other than Primus with any hardware or software not identified as
compatible by Primus. Primus shall have no obligation to correct Errors or
support Software programs except with respect to the then current and next last
current "Major Releases." "Major Releases" means a new release of a Software
program with a change in the YY component of that Software program's X.YY.ZZ
version number. It shall be a condition to Primus' provision of Secondline
Support that Distributor shall be current on its Support and Maintenance fee
payments for all of the Software.

Agreement, and whether or not an arbitration or mediation has yet been
initiated, all courts having jurisdiction over one or more of the parties are
authorized to: (i) issue and enforce in any lawful manner such temporary
restraining orders, preliminary injunctions and other interim measures of relief
as may be necessary to prevent harm to a party's interests or as otherwise may
be appropriate pending the conclusion of arbitration proceedings pursuant to

adversely restricted by reason of any circumstances beyond the reason-able
control and without the fault or negligence of the party affected, then the
party affected, upon giving prompt written notice to the other party, shall be
excused from such performance on a day-to-day basis to the extent of such
restriction (and the other party shall likewise be excused from performance of
its obligations on a day-to-day basis to the extent such party's obligations
relate to the performance so restricted); provided, however, that the party so
affected shall use all commercially reasonable efforts to avoid or remove such
causes of non-performance and both parties shall proceed whenever such causes
are removed or cease.

3.  Exclusion of Certain Claims. IN NO EVENT SHALL PRIMUS BE LIABLE (WHETHER IN
    ---------------------------                                                
TORT OR CONTRACT, UNDER STATUTE OR OTHERWISE) FOR ANY INDIRECT, SPECIAL,

or otherwise fails to perform its obligations hereunder. Accordingly, subject to
Section 1 of this Schedule, each of them shall have the right, in addition to
any other rights each of them may have, to obtain in any court of competent
jurisdiction, temporary, preliminary and permanent injunctive relief to restrain
any breach, threatened breach, or otherwise to specifically enforce any of the
obligations in this Agreement.

<PAGE>
 
remainder of this Agreement or the remainder of which such invalid provision is
a part. If any provision of this Agreement is so broad as to be held
unenforceable, such provision shall be interpreted to be only so broad as is
enforceable.

9.  Assignment. Distributor shall not assign any of its rights this Agreement
    ----------                                                               
without the prior written consent of Primus, which shall not be unreasonably
withheld. Subject to the foregoing restriction on assignment by Distributor,
this Agreement shall be binding upon, inure to the benefit of and be enforceable
by the parties and their respective successors and assigns. Primus may assign
all or any of its rights to enforce this Agreement to any licensor of Primus.

the first page of this Agreement. Either party may from time to time change its
address by giving the other party notice of the change in accordance with this
Section.

11.  Entire Agreement; Amendments. This Agreement constitutes and embodies the

entire agreement and understanding between the parties with respect to the
subject matter hereof and supersedes all prior or contemporaneous written,
electronic or oral communications, representations, agreements or understandings
between the parties with respect thereto. This Agreement may not be modified or
amended except by a written instrument executed by both parties. Only executive
officers of Primus shall have authority to amend this Agreement on behalf of
Primus. In the event of any conflict between the provisions of this Agreement

limitation any attached as a schedule or exhibit to this Agreement), the
provisions of this Agreement shall prevail. Distributor's standard terms of
purchase, if any, are inapplicable.

12.  Counterparts. This Agreement and any amendments hereto may be executed in
     ------------

                        Seagate Licensing Restrictions

- --------------------------------------------------------------------------------
                  SEAGATE'S MINIMUM TERMS OF END USER LICENSE
- --------------------------------------------------------------------------------

To the extent that the Seagate products are not shipped by Primus subject to a
shrink-wrap or click-wrap license agreement, each End User License must contain
the following minimum (or substantially similar), terms and conditions
applicable to Seagate Products (sometimes for purposes of this Exhibit D, the
"Software"), modified as necessary for multi-copy packages:

APPLICABLE TO ALL SEAGATE PRODUCTS:
- ---------------------------------- 

1. GRANT OF LICENSE. The End User is granted a personal, nonexclusive license to
use a single copy of the software program, including any updates, additional
modules, or additional software provided by Seagate in connection therewith (the
"Software") solely for End User's own use in conjunction with the OEM Product or
System, and solely in accordance with the terms and conditions of this license
agreement. End User may copy the Software into the memory of any computer,
solely as necessary to use the Software in accordance with this license
agreement.

2. OEM PRODUCT ACCESS. The license granted is qualified, in that the End User's
licensed copy of the Seagate Software may only be used with the third party
(OEM) product with which it was provided. Accessing data that is not created by,
or used by, the third party (OEM) product is in violation of the End User's
license.

3. THIRD PARTY BENEFICIARY. End User is notified that Seagate Software
Information Management Group, Inc., ("Seagate") is a third-party beneficiary to
the End User License to the extent it relates to use of the Seagate Software.
Such provisions are made expressly for the benefit of Seagate and are
enforceable by both OEM and Seagate.

4. COPYRIGHT AND COPIES.  The Software (including any copy thereof), is owned
by Seagate or its suppliers and is protected by United States copyright and
patent laws and international treaty provisions.  The Software copy is licensed,
not sold to you, and you are not an owner of any copy thereof.   You may either
(a) make one copy of the Software solely for backup or archival purposes, or (b)
transfer the Software to a single hard disk provided you keep the original
solely for backup or archival purposes.  You may not otherwise copy the
Software, except as necessary to use the OEM Product or System or as authorized
by applicable law, and you may not copy the written materials accompanying the
Software.  Seagate hereby reserves all rights not explicitly granted in this
software license agreement.

5. OTHER RESTRICTIONS.  You may not rent or lease the Software, but you may
transfer the Software and accompanying written materials on a permanent basis
provided you retain no copies and the recipient agrees to the terms of this
Agreement.  If the Software is an update, any transfer must include the update
and all prior versions.    You may not modify or translate the Software.  You
may not reverse engineer, decompile or disassemble the Software, except to the
extent expressly authorized by applicable law.  End User may not remove, alter
or destroy any form of copyright notice, proprietary markings or confidential
legends placed upon or contained within the Software.

6. DUAL MEDIA.  If the Software package contains more than one form of media,
such as a 3.5" diskette and a CD-ROM, then you may use only the media
appropriate for your computer or computer system.  You may not use the other
media on another computer or loan, rent, lease, or transfer them to another
except as part of the permanent transfer (as provided above), of all Software
and written materials.

7. NO WARRANTY.  TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE
Software PROVIDED TO END USER HEREUNDER IS PROVIDED BY SEAGATE "AS IS" WITHOUT
ANY CONDITION OR WARRANTY WHATSOEVER.  THE ENTIRE RISK ASSOCIATED WITH THE
INSTALLATION AND USE OF THE Software RESIDES WITH END USER.  ALL OTHER
CONDITIONS OR WARRANTIES, EITHER EXPRESS OR IMPLIED, ARE DISCLAIMED BY SEAGATE,
INCLUDING, WITHOUT LIMITATION, THE IMPLIED CONDITIONS OR WARRANTIES OF
MERCHANTABILITY, OWNERSHIP AND FITNESS FOR A PARTICULAR PURPOSE.  SEAGATE SHALL
NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR OTHER
DAMAGES.

8. TERM.  This license is effective until terminated.  End User may terminate
it at any time by destroying the Software together with all copies,
modifications and merged portions in any form.  It will also terminate
automatically upon End user's failure to comply with any term or condition of
this Agreement.  In the event of such termination, End User agrees to promptly
destroy the Software together with all copies, modifications and merged portions
in any form.

9. MISCELLANEOUS. The terms and conditions herein state the entire license
agreement with End user relative to any Seagate Software, and supersede any
prior agreement, whether written or oral, relating to the subject matter hereof.
The parties disclaim the application of the United Nations Convention on the

the generality of the foregoing, Licensee shall use the Software only for the
purposes specified in Section 2.2 and in accordance with the following:

  2.3.1  Licensee shall not reproduce, install or use (or permit any Authorized
SB User to reproduce, install or use) the Client Software on any computer

an Authorized Server with the Server Software to a different Licensed Site,
Licensee must notify Primus promptly following such change with the model and
serial number of the new Authorized Server and/or the address of the new
Licensed Site, as applicable.  Licensee need not comply with the above procedure
if the relocation is done temporarily while an Authorized Server is inoperable.

  2.3.3  Licensee may provide copies of the Client Software and use of the SB
Server Software on Licensee's Authorized Server for use in accordance with the

create, by reverse engineering or otherwise, the source code from the object
code supplied hereunder or use it to create a derivative work or knowingly allow
any third party to do so except that Licensee may integrate the Software with
another computer program for use on the Authorized Workstations and the
Authorized Servers.  Any portion of the Software so integrated will be subject
to the terms of this Agreement. Without limiting the generality of the
foregoing, Licensee shall not use Software as a basis to create or develop any
standalone software program to perform the same functions as the Software that
(i) incorporates any portion of the Software or (ii) makes direct function calls
to or operation of which is otherwise dependent upon any portion of the
Software, unless independently developed by Licensee without access or reference
to the Software.

  2.3.6  Except as expressly authorized in Sections 2.3.3 or 5.5, Licensee shall
not sublicense, sell, lend, rent, lease, give, transfer, assign, or otherwise

Software in violation of any applicable export control laws.  Without limiting
the generality of the foregoing, Licensee shall not export or re-export the

shall provide Primus with any "Letter of Assurance" required to be obtained by
Primus under United States export laws and regulations.

  2.3.8  In addition to its reproduction rights with regard to the Client
Software under the License, Licensee may reproduce the Software as necessary for
bona fide back-up or archival purposes only.  Licensee shall be responsible for
maintaining current archival copies of Licensee's data and Licensee expressly
releases Primus from liability for any loss of data, corruption or other damage
of such data for any reason, including without limitation, loss, corruption or
damage occurring as result of a failure of the Software to operate as set forth
in the Documentation.  This release shall not extend to loss or damage arising
out of Primus' gross negligence or willful misconduct.

  2.3.9  Licensee assumes full responsibility for any changes, modifications or
improvements to the Software made by any person other than Primus or Primus'
authorized agent.  To the extent that they arise out of any such changes,
modifications or improvements, Licensee hereby releases Primus from all
liability and waives all rights, claims and remedies against Primus, for any and
all damages of any kind or nature, to the extent they result from such acts.

or representative of Licensee or such Authorized User, Licensee shall use
reasonable efforts to terminate such unauthorized use and to retrieve any copy
of the Software in the possession or control of the person engaging in such
unauthorized use.  Licensee shall promptly notify Primus of any legal proceeding
initiated by Licensee in connection with such unauthorized use.  Primus may, at
its option and expense, participate in any such proceeding and, in such event,
Licensee shall provide such authority, information and assistance related to
such proceeding as Primus may reasonably request to protect Primus' interests,
at Primus' expense.

ownership of the Software or any copy of the Software, but only the right to use
the Software in strict accordance with this Agreement.  Licensee acknowledges
the representation that Primus and Primus' licensors are the sole and exclusive
owners of the Software; that the Software and all technical data and information
associated therewith constitute trade secrets and are the valuable property of

any value added or similar taxes payable with respect to the licensing of the
Software to Licensee, or arising out of or in connection with this Agreement,
other than taxes levied or imposed in the United States of America based upon
Primus' income.  If Licensee has tax-exempt status, a certificate or other
evidence of such tax exemption shall be provided with Licensee's purchase order.
If the parties agree in writing that Primus shall ship Software or Documentation
outside the United States, and that Licensee shall pay related fees to Primus
from outside the United States, then the provisions of subsection 3.4.1.2 shall
apply. Neither party shall be under any obligation to enter into any such
agreement by virtue of this Agreement.

      3.4.1.2   If applicable law of any country from which Licensee pays fees
to Primus, or to which Licensee ships Software to Licensee, requires Licensee to
withhold any income taxes levied by the country authorities on payments to be
made pursuant to this Agreement ("Withholding Taxes"), Licensee shall take
advantage of the reduced Withholding Tax provided for by the country/United
States tax treaty then in force and shall be entitled to deduct such Withholding
Tax from the payments due to Primus under this Agreement.  Licensee shall
promptly effect payment of the Withholding Tax to the appropriate tax
authorities and shall transmit to Primus within 15 days of such payment official
tax receipts or other evidence issued by the appropriate tax authorities
sufficient to enable Primus to support a claim for income tax credits in the
United States.  Licensee further shall assist Primus at Primus' expense, upon
request, if Primus contests to the country government in question, by
appropriate legal or administrative proceedings, the validity or amount of the
Withholding Tax.  In the event that Primus does not receive official tax
receipts within 30 days, Primus shall have the right to invoice Licensee for
such Withholding Tax and Licensee agrees to pay such amounts upon receipt of
invoice.

- ----------  ----------------------- 

4.1  Warranties.
     ---------- 

  4.1.1  Primus warrants to Licensee for a period of one hundred twenty (120)
days from the date of shipment by Primus that the media on which the Software is
distributed will be free from defects in materials and workmanship;

  4.1.2  Primus warrants to Licensee for a period of one hundred twenty (120)
days from the date of shipment of such Software by Primus to Licensee that the
Software shall perform in all material respects in accordance with the
applicable specifications set forth in the Documentation delivered by Primus and
in attachments or exhibits to this Agreement; and

  4.1.3  Primus warrants to Licensee that the Software does not infringe any
valid copyright, patent, trademark, trade secret or other intellectual property
of a third party arising under the laws of the United States. Primus warrants to
Licensee that, to the best of Primus' knowledge, the Software does not infringe
any valid third party copyright existing in any of the following countries:  the
United Kingdom; Singapore.

  4.1.4  Without limiting the foregoing, Primus does not warrant that the
Software is free from all bugs, errors, or omissions.  The warranties set forth
in this Section 4.1 apply only to the latest release of the Software made
available by Primus to Licensee.  Such warranties shall automatically terminate
if the Software has been subjected to damage or abuse or Licensee modifies or
operates the Software in any manner inconsistent with the Documentation.

  4.1.5  Primus represents and warrants that it is the true owner of the
Software and possesses all rights, authority and permission to grant the rights
and uses to Licensee permitted under this Agreement, including, such rights from
Primus' licensor(s) to sublicense any of its material incorporated into the
Software.

4.2  Performance Remedy.  If any Software subject to the warranties set forth in
     ------------------                                                         
Section 4.1 fails to comply with the warranty set forth in Sections 4.1.1 or
4.1.2 and Licensee provides written notice of the same within the warranty
period, Primus will either repair or, at its option, replace any non-complying
media or Software.  If Primus is unable to correct the noncompliance within
thirty (30) days of receipt of such written notice from Licensee, Primus may,
after consultation with Licensee,  promptly refund all of the license fees paid
for the Software, in full satisfaction of Licensee's claims for media or
Software failure, and immediately terminate the License.  Such consultation
shall include, at a minimum, negotiation between the parties to determine terms
under which Licensee may continue to use the non-conforming Software, and under
which Primus may continue work to remedy such non-conformity without incurring a
commercially unreasonable loss. Upon such termination, Licensee shall return or
destroy the Software as provided for under Section 2.7.4.  Any replacement media
or Software will be warranted for an additional one hundred twenty (120) day
period.

4.3  Infringement Remedy.  Primus shall defend Licensee against any proceeding
     -------------------                                                      
based upon any failure to satisfy the warranty set forth in Section 4.1.3,
provided that (a) Licensee notifies Primus of the proceeding promptly after it
has commenced, (b) Primus has exclusive control over the defense and settlement
of the proceeding, (c) Licensee provides such assistance in defense of the
proceeding as Primus may reasonably request, at Primus' reasonable expense, and
(d) Licensee complies with any settlement or court order made in connection with
the proceeding (e.g., relating to the future use of any infringing Software),
provided Primus complies with the provisions for remedying the problem as
specified below.  Further, Primus shall: (i) indemnify Licensee against any and
all damages, costs, and attorneys' fees finally awarded against Licensee in any
infringement proceeding under this Section 4.3, (ii) reimburse the expenses
reasonably incurred by Licensee to provide the assistance requested by Primus
under (c) above, and (iii) if the action is settled, pay any amounts agreed to
by Primus in settlement of any claims of infringement.  Primus shall have no
liability under Section 4.1.3 or this Section 4.3 for any claim of infringement
arising out of Licensee's modification of the Software or for any claim arising
out of the combination of the Software with a program, product, or material not
furnished by Primus, to the extent such infringement would not have occurred but
for such modification or combination.  In the event that use of the Software
becomes, or in Primus' reasonable opinion is likely to become, the subject of a
claim of infringement of copyright, patent, trademark, trade secret or other
intellectual property of a third party, it is Primus' option to remedy

                                  Page 3 of 7
<PAGE>
 
the situation by: (i) procuring the continuing right of Licensee to use the
Software; (ii) replacing or modifying the Software in a functionally equivalent
manner so that it no longer infringes; or (iii) with Licensee's consent,
terminating the License and refunding to Licensee an amount equal to the
depreciated License fee paid by Licensee (calculated on a straight line basis
over a three (3) year life). Upon such termination, Licensee shall return or
destroy the Software as provided for under Section 2.7.4.

4.4  Exclusivity; Disclaimer.  Primus makes no representation or warranty with
     -----------------------                                                  
regard to the Software or other items furnished under this Agreement, except as
set forth in Section 4.1.  The obligations of Primus under Sections 4.2 and 4.3
are the sole and exclusive remedies of Licensee regarding any noncompliance with
the warranties set forth in Section 4.1.  EXCEPT AS SPECIFICALLY SET FORTH IN
THIS SECTION 4, PRIMUS DISCLAIMS AND LICENSEE WAIVES AND RELEASES ALL RIGHTS AND
REMEDIES OF LICENSEE, AND ALL WARRANTIES, OBLIGATIONS, AND LIABILITIES OF
PRIMUS, EXPRESS OR IMPLIED, ARISING BY LAW OR OTHERWISE, WITH RESPECT TO ANY
BUG, ERROR, OMISSION, DEFECT, DEFICIENCY, OR NONCONFORMITY IN ANY SOFTWARE,
WARRANTY SERVICES, OR OTHER ITEMS FURNISHED UNDER THIS AGREEMENT, INCLUDING BUT
NOT LIMITED TO ANY: (A) IMPLIED WARRANTY OF MERCHANTABILITY OR FITNESS FOR A
PARTICULAR PURPOSE; (B) IMPLIED WARRANTY ARISING FROM COURSE OF PERFORMANCE,
COURSE OF DEALING, OR USAGE OF TRADE;OR (C) CLAIM OF INFRINGEMENT.

4.5  Excused Performance; Force Majeure.  If the performance of this Agreement
     ----------------------------------                                       
is adversely restricted by reason of any circumstances beyond the reasonable
control and without the fault or negligence of the party affected, then the
party affected, upon giving prompt written notice to the other party, shall be
excused from such performance on a day-to-day basis to the extent of such
restriction (and the other party shall likewise be excused from performance of
its obligations on a day-to-day basis to the extent such party's obligations
relate to the performance so restricted); provided, however, that the party so
affected shall use all commercially reasonable efforts to avoid or remove such
causes of non-performance and both parties shall proceed whenever such causes
are removed or cease.

Section 5.  Miscellaneous.
- ----------  ------------- 

5.1  Limitation of Remedy.  IN NO EVENT SHALL EITHER PARTY BE LIABLE (WHETHER IN
     --------------------                                                       
TORT, NEGLIGENCE, CONTRACT, WARRANTY, PRODUCT LIABILITY OR OTHERWISE) FOR ANY
INDIRECT, INCIDENTAL, SPECIAL OR CONSEQUENTIAL DAMAGES OR LOSS OF PROFITS OR

     ------------------------                                               
4.3, neither party's liability (whether in tort, negligence, contract, warranty,
product liability or otherwise) with regard to this Agreement or any Software or
other items furnished under this Agreement shall exceed the license fees paid by
Licensee to Primus under this Agreement.

     -----------------                                                      
respective obligations with respect to the use and provision of the Software are
essential elements of the transactions contemplated in this Agreement; that, but
for the agreement of each of them to comply with such obligations, the other
would not have entered into this Agreement; and that damages will be an
inadequate remedy if the other violates the terms of this Agreement, or
otherwise fails to perform its obligations hereunder.  Accordingly, each of them
shall have the right, in addition to any other rights each of them may have, to

               may use the applicable Software program by accessing the
               Authorized Server(s). Licensee shall ensure that only one
               personal user ID is assigned to each individual Authorized User,
               and that no more than one individual Authorized User uses any one
               personal user ID and linked password. "Individual" Authorized
               User means an individual person, and not a corporation, company,
               partnership, association or other entity or organization.

                    Concurrent Users. Where a number of Authorized Users is
               specified in Exhibit A as a concurrent user, up to that number of
               individual Authorized Users may use the applicable Software
               program on a concurrent user basis by accessing the Authorized
               Server(s), without regard to the user ID of the individual.

               so forth) that are agreed in writing between Primus and Licensee.

Note 1:  Product Flexibility
- ----------------------------
Licensee has not yet determined the exact number of Authorized Workstations of
SolutionBuilder Software and Authorized Users (personal ID) of SolutionExplorer
Software that it requires, although Licensee has finally determined to make an
aggregate investment in such products in an amount of [*].  Therefore, Licensee 
wishes to have, and Primus is willing to provide Licensee with the flexibility
to substitute Authorized Workstations of SolutionBuilder Software for Authorized
Users (personal ID) of Primus' SolutionExplorer software, and vice-versa.
Accordingly, Licensee may substitute Authorized Workstations of SolutionBuilder
Software for Authorized Users (personal ID) of SolutionExplorer Software that
Primus has licensed to it under this Exhibit A-1 and this Agreement, on a one-
for-one basis, and vice-versa; provided always, however, that the aggregate
number of Authorized Workstations and Authorized Users (personal ID) of such
Software may not exceed [*].

Note 2: Fees for Authorized Servers.
- ----------------------------------- 

Notwithstanding the provisions of Section 3.1.2, Primus shall not charge
Licensee any fees for (i) Authorized Servers on which Licensee has, in good
faith, installed the Software prior to the date on which Primus executes this
Exhibit A-1, and (ii) Authorized Servers on which Licensee, in good faith,
installs the Software, the rights to which Licensee has acquired pursuant to
this Exhibit A-1.

The options granted above shall be exercised by delivery of an irrevocable
purchase order to Primus for the applicable number of workstations and users
(collectively, "Seats") at the applicable price, on or before the relevant
option expiration date.  Licensee shall pay the requisite license fees within
thirty (30) days of the date on which the purchase order is delivered to Primus.
Upon exercise of all or any part of the options, Licensee shall pay support and
maintenance fees upon the number of Seats acquired, at a rate of [*] percent
[*] of the per Seat price, multiplied by the number of Seats acquired.
Support and maintenance services will be subject to the provisions of the
Support and Maintenance Agreement.

Additional Obligations of Primus.
- -------------------------------- 

Primus will deliver the following two additional capabilities for the Software
to Licensee in a general release version on or before March 31, 1999. Primus
shall be solely responsible for determining whether the Software contains such
capabilities, but shall make such determination in good faith and on a
reasonable basis. The date on which Primus delivers such capabilities is
referred to in this Exhibit A-1 as the "Enhancement Delivery Date." On or before
the 30th day following the Enhancement Delivery Date, Licensee shall pay Primus
the License fee balance of [*] US Dollars (US $[*]), as specified in the Payment
Terms table above.

Extended Attributes:  The SolutionBuilder, SolutionExplorer, SolutionX(TM) and
SolutionReports applications will be extended to allow the site administrator to
define up to six additional solution attributes.  The site administrator will
have the ability to name the attribute as well as define a list of acceptable
values and a default for that attribute.  The application user will be presented
with the attributes identified by their given names as well as a default value
and a pull down list of acceptable values for each.  The attributes will also be
available for solution query, solution search constraint, SolutionX query and
solution reporting.  It will also be possible to set the value of an attribute
as a search constraint from call tracking or from the product selection
mechanism in the SolutionPublisher application.  In the SolutionPublisher and
SolutionExplorer applications an option will be available to hide any attribute
on the user interface.

Application Security:  Security will be added enabling any solution or statement
to be removed from the end user's view by setting a security attribute
controlling their visibility.  A single security attribute will be added to the
SolutionBuilder and SolutionExplorer applications for the purpose of controlling
access to solutions.  The site administrator will be able to create up to 64
user security groups via SolutionAdmin.  The security attribute will have a pull
down list of all of the user security groups (defined in SolutionAdmin).  When
the value of the attribute is set to a group, only users added to that group
will have access to that solution.  A users denied access to a secured solution
will be denied access in the following ways:  the solution will not be returned
in a solution search, the solution will not be returned in a query, the solution
will not be available if opened by ID,  no statements that exist exclusively in
solutions to which a user has no access will be returned in a statement matching
operation.

Technical Assistance.  Upon request by Licensee, Primus shall assist Licensee
- --------------------                                                         
with Licensee's utilization of any of the Software, including any upgrade, on a
time and materials basis, and on such written terms and conditions as may be
reasonably acceptable to each of Primus and Licensee.  Primus shall provide such
assistance at a per labor day rate of $[*] for the period ending August 31,
1999.  On September 1, 1999 and each anniversary thereof, Primus may increase
such rate by a percentage of the previous

labor day rate that is equal to the percentage increase in the All Cities
Average United States Consumer Price Index (all items, base period 1982-84=100)
for the nearest published one year period preceding that September 1, as
published by the US Department of Labor. Primus shall not mark up any materials
that it obtains for, or provides to Licensee, except with Licensee's prior
written consent.

Re:  Third Amendment to Software License Agreement and Second Amendment to
     Support and Maintenance Agreement, dated as of August 28, 1998
     (collectively, the "Amendment") Between 3Com Corporation ("3Com") and
     Primus Knowledge Solutions, Inc. ("Primus")  Delivery of Additional
     Capabilities by Primus

Dear Dave:

Introduction
This letter is to confirm our agreement that Primus has fulfilled certain of its
obligations under the Amendment (defined above).  Capitalized terms not
otherwise expressly defined in this letter shall have the meaning ascribed to
them in the Software License Agreement, dated as of June 27, 1997, between
Primus and 3Com, as amended (the "Software License Agreement").

Primus' Obligations To Deliver Certain Enhancements
Under the Amendment, Primus is obligated to deliver to 3Com on or before March
31, 1999 certain  enhancements to the Software, as specified in the two
paragraphs immediately below (collectively, the "Additional Obligations")

     "Extended Attributes:  The SolutionBuilder, SolutionExplorer, SolutionX(TM)
      -------------------                                                       
     and SolutionReports applications will be extended to allow the site
     administrator to define up to six additional solution attributes.  The site
     administrator will have the ability to name the attribute as well as define
     a list of acceptable values and a default for that attribute.  The
     application user will be presented with the attributes identified by their
     given names as well as a default value and a pull down list of acceptable
     values for each.  The attributes will also be available for solution query,
     solution search constraint, SolutionX query and solution reporting.  It
     will also be possible to set the value of an attribute as a search
     constraint from call tracking or from the product selection mechanism in
     the SolutionPublisher application.  In the SolutionPublisher and
     SolutionExplorer applications an option will be available to hide any
     attribute on the user interface.

     Application Security:  Security will be added enabling any solution or
     --------------------                                                  
     statement to be removed from the end user's view by setting a security
     attribute controlling their visibility.  A single security attribute will
     be added to the SolutionBuilder and SolutionExplorer applications for the
     purpose of controlling access to solutions.  The site administrator will be
     able to create up to 64 user security groups via SolutionAdmin.  The
     security attribute will have a pull down list of all of the user security
     groups (defined in

<PAGE>
 
3Com Corporation

Page 2 of 2

     SolutionAdmin). When the value of the attribute is set to a group, only
     users added to that group will have access to that solution. A users denied
     access to a secured solution will be denied access in the following ways:
     the solution will not be returned in a solution search, the solution will
     not be returned in a query, the solution will not be available if opened by
     ID, no statements that exist exclusively in solutions to which a user has
     no access will be returned in a statement matching operation."

Primus' Fulfillment Of Its Obligations
Based upon the enhancements to the Software that Primus has delivered to 3Com
(the "Enhancements"), and the results of tests performed by 3Com on the
Enhancements, Primus has determined that it has fulfilled the Additional
Obligations as of the date of this letter.  3Com agrees with Primus'
determination.

Confirmation Of Certain Rights Of 3Com With Respect To The Enhancements
Each of 3Com and Primus acknowledge that (i) the Enhancements constitute
Software under the Software License Agreement; (ii) the warranty provisions of
the Software License Agreement apply to the Enhancements; and (iii) Primus is
obligated to provide 3Com with technical support and upgrades relating to the
Enhancements pursuant to the Support and Maintenance Agreement, dated as of June
27, 1997, between Primus and 3Com, as amended.

Please indicate your agreement to the terms of this letter by executing the
enclosed duplicate in the space provided below.

Sincerely,

PRIMUS KNOWLEDGE SOLUTIONS, INC.

circumvent or mitigate the impact of an Error.  The Error still exists.  A
Workaround may be provided at Primus' discretion in lieu of a Fix for a specific
Error.

Section 2.  Scope of Support and Maintenance Services.
- ------------------------------------------------------

2.1  Services Provided.  During the term of this Agreement, Primus shall support
     -----------------                                                          
Licensed Program(s) by providing the services described in the following
paragraphs of this Section 2.  Primus has no obligation to correct or support

Licensed Program(s), or Customer's combining or merging Licensed Program(s) with
any hardware or software not identified as compatible by Primus.

2.2  Technical Support.  Primus will provide telephone technical support
     ------------------                                                 
regarding use of the Licensed Program(s) and resolution of Errors to Customer's
Support Contacts designated under Section 2.6.2.  Primus technical support
representatives will be available by telephone Monday through Friday from 5:00
a.m. to 5:30 p.m. PDT/PST.  In addition, on-call technical support staff will be

(30) minutes of receiving the page triggered by the Customer's voice message for
High Priority situations described below.

2.3  Support Response.  Primus will assign all Customer requests for Error
     ----------------                                                     
support one of three response priorities which will dictate the timing and
nature of the response as follows:

  High Priority.  A major feature/function of the Licensed Program(s) is not
  -------------                                                             
  working or the system integrity is at risk.

  Response Goal:  Endeavor to provide a Fix or Workaround within twenty-four
  (24) hours of Customer's report of the problem.  If the Fix or Workaround
  cannot be provided within the twenty-four (24) hours Primus will dedicate
  resources to the problem resolution and will inform Customer on a daily basis
  of the resolution status.

  Medium Priority.  Customer's work flow is inhibited or a non-major
  ---------------                                                   
  feature/function of the Licensed Programs is not working.

  Response Goal:  Endeavor to provide a Fix or Workaround within two (2)
  business days of the Customer's report of the problem.  If the problem cannot
  be resolved within the two (2) business days, Primus will inform Customer on a
  weekly basis of the resolution status.

  Low Priority.  Customer has a problem which is not seriously impacting
  ------------                                                          
  Customer's workflow.

  Response Goal:  Endeavor to provide a Fix or a Workaround within five (5)
  business days of Customer's report of the problem.  If the problem cannot be
  resolved within the five (5) business days, Primus will provide Customer with
  a status evaluation regarding the ultimate resolution.

2.4  Subsequent Release(s).  Primus will send Major Releases, New Versions,
     ---------------------                                                 
Maintenance Releases and Fixes and Workarounds (for the same platforms as
Customer's) to Customer when made generally commercially available by Primus to
its customers.  Maintenance Releases will be provided to Customer pursuant to
Section 2.3 when Customer is experiencing or in Primus' sole judgment may
experience an Error.  Each Major Release, Maintenance Release, New Version, Fix
and Workaround delivered by Primus under this Agreement is subject to the
provisions of the License Agreement between Primus and Customer and shall be
automatically deemed to be included under the definition of Software under the
License Agreement.

2.5  Limits of Support.
     ----------------- 

  2.5.1  Seattle Headquarters.  This Agreement covers the support that Primus is
         --------------------                                                   
able to provide for a Licensed Program(s) from its Seattle headquarters by
telephone, fax or electronic mail.  In the event that Customer desires or
requires on-site support for a Licensed Program(s), the parties will have to
negotiate that issue separately.

2.6  Customer Cooperation and Support Contacts.
     ----------------------------------------- 

  2.6.1  Customer Cooperation.  Customer acknowledges that Primus may not be
         --------------------                                               
able to resolve an Error if Customer does not use its commercially reasonable
best efforts to cooperate with and assist Primus in resolving the Error.

  2.6.2  Support Contacts.  Customer will designate two (2) authorized Support
         ----------------                                                     
Contacts and agrees that each Support Contact will be knowledgeable in all
aspects of the Customer's operating environment in which Licensed Programs are
being used.

  2.6.3  3Com Corporation and Subsidiaries. 3Com Corporation warrants and
         ---------------------------------                               
guarantees to Primus that 3Com Corporation and its wholly-owned subsidiaries

                          Change of Control Agreement

     This Change of Control Agreement (this "Agreement"), dated as of
              , 1999, is between PRIMUS KNOWLEDGE SOLUTIONS, INC., a Washington
- --------------
corporation (the "Company"), and                   (the "Employee").
                                 -----------------

                                    RECITAL

     The Board of Directors of the Company (the "Board") has determined that it
is in the best interests of the Company and its shareholders to ensure that the
Company will have the continued dedication of the Employee, notwithstanding the
possibility, threat or occurrence of a Change of Control (as defined in Section
1.1 hereof) of the Company.  The Board believes it is imperative to diminish the
inevitable distraction of the Employee arising from the personal uncertainties
and risks created by a pending or threatened Change of Control, to encourage the
Employee's full attention and dedication to the Company currently and in the
event of any threatened or pending Change of Control, and to provide the
Employee with reasonable compensation and benefit arrangements upon a Change of
Control.

                                   AGREEMENT

     In order to accomplish these objectives, the Board has caused the Company
to enter into this Agreement.

immediately prior to such merger, consolidation or share exchange own less than
a majority of the outstanding voting securities of the surviving corporation;

     (b) Consummation of any sale, lease, exchange or other transfer in one
transaction or a series of related transactions of all or substantially all of
the Company's assets other than a transfer of the Company's assets to a
majority-owned subsidiary of the Company; or
<PAGE>
 
     (c) Acquisition by a person, within the meaning of Section 3(a)(9) or of
Section 13(d)(3) of the Exchange Act of 1934, as amended (the "Exchange Act") of
a majority or more of the Company's outstanding voting securities (whether

     "Change of Control Date" shall mean the first date on which a Change of
Control occurs.

     1.3  Employment Period

     "Employment Period" shall mean the one-year period commencing on the Change

- --------                                                 --------
Company's common stock (the "               Options").
                             --------------
4.   ACCELERATION OF VESTING

     Immediately prior to closing of a Change of Control fifty percent (50%) of
the unvested portion of the                Options shall automatically become
                            --------------
fully vested and exercisable whether or not the vesting requirements set forth
in the applicable Option Agreement[s] have been satisfied.

5.   EMPLOYMENT

     5.1  Employment Period

     During the Employment Period, the Company hereby agrees to continue the
Employee in its employ or in the employ of its affiliated companies, and the
Employee hereby agrees to remain in the employ of the Company or its affiliated
companies, in accordance with the terms and provisions of this Agreement;
provided, 

                                       2
<PAGE>
 
however, that either the Company or the Employee may terminate the employment
relationship subject to the terms of this Agreement.

     5.2  Position and Duties

     During the Employment Period, the Employee's title, position, authority,
duties and responsibilities shall be at least commensurate in all material
respects with the most significant of those held, exercised and assigned at any
time during the 90-day period immediately preceding the Change of Control Date.

     5.4  Termination Prior to Change of Control

     If prior to the Change of Control Date, the Employee's employment with the
Company or its affiliated companies terminates for any reason, then the Employee
shall have no further rights under this Agreement; provided, however, that the
Company may not avoid liability for any termination payments which would have
been required during the Employment Period pursuant to Section 9 hereof by
terminating the Employee prior to the Employment Period where such termination
is carried out in anticipation of a Change of Control and the principal
motivating purpose is to avoid liability for such termination payments.

deliver lectures, fulfill speaking engagements or teach at educational
institutions, (c) manage personal investments, so long as such activities do not
significantly interfere with the performance of the Employee's responsibilities
in accordance with this Agreement and (d) other activities approved in advance
by the Company.  It is expressly understood and agreed that to the extent any
such activities have been conducted by the Employee prior to the Employment
Period, the continued 

                                       3
<PAGE>
 
conduct of such activities (or the conduct of activities similar in nature and

equal installments and at the same intervals as the salaries of other employees
of the Company are paid.  The Board or the Compensation Committee shall review
the Annual Base Salary at least annually and shall determine in good faith and
consistent with any generally applicable Company policy any increases for future
years.

     7.2  Bonus

     In addition to Annual Base Salary, the Employee shall be awarded an annual
bonus (the "Annual Bonus") in cash at least equal to the average annualized (for
any fiscal year consisting of less than 12 full months) bonus paid or payable,
including by reason of any deferral, to the Employee by the Company and its
affiliated companies in respect of the three fiscal years immediately preceding
the fiscal year in which the Change of Control Date occurs.  Each such Annual
Bonus shall be paid no later than 90 days after the end of the fiscal year for
which the Annual Bonus is awarded, unless the Employee shall elect to defer the
receipt of such Annual Bonus.

or committee appointed by the Board to determine fringe benefit programs and
other emoluments), including, without limitation, paid vacations; any stock
purchase, savings or retirement plan, practice, policy or program; and all
welfare benefit plans, practices, policies or programs

affiliated companies during the Employment Period.

8.   TERMINATION

     During the Employment Period, employment of the Employee may be terminated
as follows:

     8.1  By the Company or the Employee

     At any time during the Employment Period, the Company may terminate the
employment of the Employee with or without Cause (as defined below), and the
Employee may terminate his employment for Good Reason (as defined below) or for
any reason, upon giving Notice of Termination (as defined below).

     8.2  Automatic Termination

     This Agreement and the Employee's employment during the Employment Period
shall terminate automatically upon the death or Total Disability of the
Employee.  The term "Total Disability" as used herein shall mean the Employee's
inability (with such accommodation as may be required by law and which places no
undue burden on the Company), as determined by a physician selected by the
Company and acceptable to the Employee, to perform the duties set forth in
Section 5.2 hereof for a period or periods aggregating 120 calendar days in any
12-month period as a result of physical or mental illness, loss of legal
capacity or any other cause beyond the Employee's control, unless the Employee
is granted a leave of absence by the Board.  The Employee and the Company hereby
acknowledge that the duties specified in Section 5.2 hereof are essential to the
Employee's position and that Employee's ability to perform those duties is the
essence of this Agreement.

     8.3  Notice of Termination

     Any termination by the Company or by the Employee during the Employment
Period shall be communicated by Notice of Termination to the other party given
in accordance with Section 12 hereof.  The term "Notice of Termination" shall
mean a 

                                       5
<PAGE>
 
written notice which (a) indicates the specific termination provision in this
Agreement relied upon and (b) to the extent applicable, sets forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of
the Employee's employment under the provision so indicated. The failure by the
Employee or the Company to set forth in the Notice of Termination any fact or
circumstance which contributes to a showing of Good Reason or Cause shall not
waive any right of the Employee or the Company hereunder or preclude the
Employee or the Company from asserting such fact or circumstance in enforcing
the Employee's or the Company's rights hereunder.

     8.4  Date of Termination

     During the Employment Period, "Date of Termination" means (a) if the
Employee's employment is terminated by reason of death, at the end of the
calendar month in which the Employee's death occurs, (b) if the Employee's
employment is terminated by reason of Total Disability, immediately upon a
determination by the Company of the Employee's Total Disability, and (c) in all
other cases, five days after the effective date of notice pursuant to Section 12
hereof.  The Employee's employment and performance of services will continue
during such five-day period; provided, however, that the Company may, upon
notice to the Employee and without reducing the Employee's compensation during
such period, excuse the Employee from any or all of his duties during such
period.

9.   TERMINATION PAYMENTS

     In the event of termination of the Employee's employment during the
Employment Period, all compensation and benefits set forth in this Agreement
shall terminate, except as specifically provided in this Section 9.

<PAGE>
 
               (ii) any compensation previously deferred by the Employee
     (together with accrued interest or earnings thereon, if any) and any
     accrued vacation pay which would be payable under the Company's standard
     policy, in each case to the extent not theretofore paid;

          (b) an amount as severance pay equal to one-half of Employee's Annual
Base Salary for the fiscal year in which the Date of Termination occurs;
provided, that such payment shall be in full and final satisfaction of any claim
of the Employee against the Company arising out of the officer's employment by
the Company or the termination of such employment; and

          (c) immediate vesting and exercisability of all options to purchase
securities of the Company held by the Employee, including but not limited to the

the Company to the Employee, other than the Company's obligation to pay the
Employee the Accrued Obligations to the extent theretofore unpaid.

     9.3  Expiration of Term

     In the case of a termination of the Employee's employment as a result of
the expiration of the Term of this Agreement, this Agreement shall terminate

     If during the Employment Period the Employee's employment is terminated by

terminate automatically without further obligation on the part of the Company to
the Employee or his legal representatives under this Agreement, other than the
Company's obligation to pay the Employee the Accrued Obligations (which shall be
paid to the Employee's estate or beneficiary, as applicable in the case of the
Employee's death).

     9.5  Payment Schedule

     All payments of the Accrued Obligations and the Severance Obligation, or
any portion thereof payable pursuant to this Section 9, shall be made to the
Employee within thirty calendar days of the Date of Termination.

following events:

          (a) A clear refusal to carry out any material lawful duties of the
Employee or any directions of the Board, all reasonably consistent with the
duties described in Section 5.2 hereof, provided the Employee has been given

any incident materially compromising the Employee's reputation or ability to
represent the Company with investors, customers or the public.

     9.7  Good Reason

     For purposes of this Agreement, "Good Reason" means

          (a) The assignment to the Employee of any duties materially
inconsistent with the Employee's title, position, authority, duties or
responsibilities as contemplated by Section 5.2 hereof or any other action by
the Company which results in a material diminution in such title, position,
authority, duties or responsibilities;

          (b) Any failure by the Company to comply with any of the provisions of
Section 7 hereof;

          (c) The Company's requiring the Employee to be based at any office or

          (d) Any failure by the Company to comply with and satisfy Section 13

     9.8  Excess Parachute Limitation

     If either the Company or the Employee receives confirmation from the
Company's independent tax counsel or its certified public accounting firm, or
such other accounting firm retained as independent certified public accountants
for the Company (the "Tax Advisor"), that any payment by the Company to the
Employee under this Agreement or otherwise would be considered to be an "excess
parachute payment" within the meaning of Section 280G of the Internal Revenue
Code of 1986, as amended, or any successor statute then in effect (the "Code"),
then the aggregate payments by the Company pursuant to this Agreement shall be
reduced to the highest amount that may be paid to the Employee by the Company
under this Agreement without having any portion of any amount payable to the
Employee by the Company or a related entity under this Agreement or otherwise
treated as such an "excess parachute payment," and, if permitted by applicable
law and without adverse tax consequence, such reduction shall be made to the
last payment due hereunder.  Any payments made by the Company to the Employee
under this Agreement which are later confirmed by the Tax Advisor to be "excess
parachute payments" shall be considered by all parties to have been a loan by
the Company to the Employee, which loan shall be repaid by the Employee upon
demand, together with interest calculated at the lowest interest rate authorized
for such loans under the Code, without a requirement that further interest be
imputed.

10.  REPRESENTATIONS, WARRANTIES AND OTHER CONDITIONS

     In order to induce the Company to enter into this Agreement, the Employee
represents and warrants to the Company that neither the execution nor the
performance of this Agreement by the Employee will violate or conflict in any
way with any other agreement by which the Employee may be bound or with any
other duties imposed upon Employee by corporate or other statutory or common
law.

of this Agreement, other than pursuant to the definition of Cause set forth in
Section 9.6 hereof, before such action is taken, the party asserting the breach
of this Agreement shall give the other party at least ten days' prior written
notice of the existence and the nature of such breach before taking further
action hereunder and shall give the party purportedly in breach of this
Agreement the opportunity to correct such breach during the ten-day period.

1  GENERAL PROVISIONS

1.1  Purpose of the Plan

     The purpose of the Employee Stock Option and Restricted Stock Award Plan
     (the "Plan") is to provide incentives to selected employees of Primus

     the success of the business activities of the Company. The incentives will
     be in the form of options to purchase shares of the Company's common stock
     and/or restricted stock awards of the Company's common stock.

1.2  Definitions

     As used in this Plan, the following definitions will apply:

     (a)  "Employer" shall mean the Company or any parent or subsidiary of the
          Company that now exists or is hereafter organized or acquired by the

     (b)  "Employee" shall mean any person employed by or acting as an agent,
          contractor, or subcontractor for the Company or parent or subsidiary

          by the Company.

     (c)  "Shareholder-Employee" shall mean an Employee who owns stock
          representing more than ten percent (10%) of the total combined voting

     (d)  "Common Stock" shall mean the Company's common stock, par value
          $0.025.

     (e)  "Incentive Stock Options" shall mean incentive stock options within
          the meaning of Section 422 (a) of the Internal Revenue Code.

1.3  Shares Subject to the Plan

1.3.1  Total Shares Available.
       ---------------------- 

     (a)  The number of shares that may be issued and sold pursuant to Options
          granted under the Stock Option Provisions of this Plan and that may be
          issued pursuant to the Restricted Stock Award Provisions of this Plan
          will not, in the aggregate, exceed 6,700,000 shares of the Common
          Stock of the Company.

     (b)  Common Stock issued under this Plan may be either authorized and
          unissued shares or shares issued and thereafter acquired by the
          Company. If any Options granted under this Plan will, for any reason,
          expire without having been exercised in full, or if any Awards will,
          for any reason, be forfeited or canceled, the Common Stock not
          purchased under such options, or so forfeited, will be available again
          for the purposes of this Plan.

1.3.2  Adjustments to Shares Available.
       ------------------------------- 

     (a)  The number of shares of Common Stock covered by each outstanding
          Option and Award, the number of shares of Common Stock available for
          grant of additional Options and Awards, and the price per share of
          Common Stock specified in each outstanding Option, will be
          proportionately adjusted for any increase or decrease in the number of
          issued shares of Common Stock resulting from any stock split or other
          subdivision or consolidation of shares, the payment of any stock
          dividend (but only on the Common Stock), or any other increase or
          decrease in the number of such shares of Common Stock effected without
          receipt of consideration by the Company; provided, however, that
          conversion of any convertible securities of the Company will not be
          deemed to have been "effected without receipt of consideration." Such
          adjustment will be made by the Committee, whose determination in that
          respect will be final, binding, and conclusive.

     (b)  No Option will be adjusted by the Committee pursuant to Section 3 in a
          manner that causes the Option, if an Incentive Stock Option, to fail
          to continue to qualify as an Incentive Stock Option.

1.4  Administration of the Plan

1.4.1  The Committee.
       ------------- 

     (a)  This Plan will be administered by the Compensation Committee of the
          Board or such other Committee as will be appointed by the Board. The
          Committee will consist of not less than three (3) members of the
          Board; provided, however, that for as long as the Board consists of
          one Director, the Plan will be administered by that Director, who
          shall possess all powers of the Committee hereunder. Once appointed,
          the Committee will continue to serve until otherwise directed by the
          Board. From time to time, the Board may increase the size of the
          Committee and appoint additional members, remove members with or
          without cause, appoint new members in substitution for existing
          members, and fill vacancies. The Committee will select one of its
          members as chairman and will hold meetings at such times and places as
          the chairman or a majority of the Committee may determine.

     (b)  A majority of the members of the Committee, if it consists of more
          than one member, will consist of members of the Board who are not
          eligible to receive Options or Awards. Members of the Committee who
          are either eligible for Options or Awards or who have been granted
          Options or Awards will be counted for all purposes in determining the
          existence of a quorum at any meeting of the Committee and will be
          eligible to vote on all matters before the Committee, except only that
          such members will not vote or otherwise act on the grant or the
          modification of the terms of any Option or Award granted or to be
          granted to himself or herself. If the Committee consists of one
          member, that member may not grant an Option or Award to himself or
          herself.

                                       2

     (c)  The Committee will, if so requested, present a written report to the
          Board indicating the Employees to whom Options and Awards have been
          granted since the date of the last such report, and, in each case, the
          date or dates of Options and Awards granted, the number of shares
          optioned and awarded, and the Option price and Award value per share.

     (d)  The Board will have the power at any time to remove all members of the
          Committee and thereafter to directly administer this Plan as a
          Committee of the whole. In such an event, all references in the Plan
          to the "Committee" will refer to the Board.

          applicable written agreement pursuant to the Plan, the Committee will
          have the authority and discretion:

               Stock Options;

          (3)  to authorize any person or persons to execute and deliver Option
               and Award agreements or to take any other actions deemed by the

               of Options and Awards by the Committee;

          (4)  to make all other determinations and take all other actions that
               the Committee deems necessary or appropriate to administer the

          meeting of the Committee.

     (c)  All decisions, determinations, and interpretations of the Committee
          will be final and binding on all persons, including all Optionees,
          Grantees, and any other holders or persons interested in any Option or
          Award, unless otherwise expressly determined by a vote of the majority
          of the Board. No member of the Committee or of the Board will be
          liable for any action or determination made in good faith with respect
          to this Plan.

1.5  Term of the Plan

     adoption of this Plan by the Board; or (b) the date of shareholder approval
     of the Plan as set forth below. Unless sooner terminated as provided below,
     the Plan will terminate on the tenth anniversary of its effective date.
     Options may be granted at any time after the effective date and prior to
     the date of termination of the Plan.

1.5.2  Amendment or Early Termination.
       ------------------------------ 

     (a)  The Board may terminate this Plan at any time. The Board may amend
          this Plan at any time and from time to time in such respects as the
          Board may deem advisable, except that, without approval of the holders
          of a majority of the outstanding shares of the Common Stock, no such
          revision or amendment will:

          (1)  increase the number of shares of Common Stock subject to the Plan
               other than in connection with an adjustment under Section 3.2 of
               Part I; or

<PAGE>
 
     (b)  No amendment or termination of the Plan will affect Options or Awards
          granted prior to such amendment or termination, and all such Options
          and Awards will remain in full force and effect notwithstanding such

1.6  Shareholder Approval

     Continuance of the Plan will be subject to approval of the Plan by
     affirmative vote of the holders of a majority of the outstanding shares of
     Common Stock of the Company at a duly convened meeting of the shareholders
     of the Company, which approval must occur within twelve (12) months before
     or after the date of adoption of the Plan by the Board.

2  STOCK OPTION PROVISIONS

2.1  Nonqualified Stock Options and Incentive Stock Options

     Options in the form of Nonqualified Stock Options and Options that qualify
     as Incentive Stock Options may be granted under the Plan.

2.2   Eligibility for Options

     Options may be granted only to Employees whom the Committee, in its
     discretion, determines to be key Employees of the Company, a parent, or a
     subsidiary. The granting of Options will be entirely discretionary with the
     Committee, and the adoption of this Plan will not confer on any Employee
     any right to receive any Options unless and until such Options are granted
     by the Committee. Neither the adoption of this Plan nor the granting of any
     Options will confer on any Employee any right with respect to continuation
     of employment, nor will the same interfere in any way with his or her right
     (or with the right of the Employer) to terminate his or her employment at
     any time.

2.3   Terms and Conditions of Options

     All Options granted pursuant to this Plan must be authorized by the
     Committee, and must be documented in written agreements in such form as the
     Committee will from time to time approve, which agreements will comply with
     and be subject to all of the following terms and conditions:

     (a)  Number of Shares and Annual Limitation. Each Option agreement will
          --------------------------------------                            
          state the number of shares subject to the Option. Any number of
          Options may be granted to a single eligible Employee at any time and
          from time to time, except that, in the case of Incentive Stock
          Options, the aggregate fair market value (determined as of the time
          each Option is granted) of all shares of Common Stock with respect to
          which Options are exercisable for the first time by such Employee in
          any one calendar year (under all Incentive Stock Option plans of the
          Company, its parent, and all of its Subsidiaries taken together) will
          not exceed One Hundred Thousand Dollars ($100,000).

     (b)  Option Price and Consideration.
          ------------------------------ 

          (1)  The Option price for the shares of Common Stock to be issued
               pursuant to the Option will be such price as is determined by the
               Committee, but, in the case of Incentive Stock Options, will in
               no event be less than the fair market value of the Common Stock
               on the date of grant of the Incentive Stock Option.

          (2)  In the case of an Incentive Stock Option granted to an Employee
               who, immediately before the grant of such Incentive Stock Option,
               is a Shareholder-Employee, the Incentive Stock Option price will
               be at least one hundred ten percent (110%) of the fair market
               value of the Common Stock on the date of grant of the Incentive
               Stock Option. The fair market value will be determined by the
               Committee in its discretion; provided, however, that, if a public
               market exists for the Common Stock, the fair market value will be
               the mean of the bid and asked prices of the Common Stock as of
               the date of grant as reported

                                       4
<PAGE>
 
               on the National Association of Securities Dealers Automated
               Quotation System (NASDAQ), or if the Common Stock is listed on a
               stock exchange, the closing price on the exchange as of the date
               of grant of the Option.

          (3)  The Option price will be payable either (i) in United States
               dollars on exercise of the Option, or (ii) if so determined by
               the Committee and specified in the Option agreement, in other
               property, including, without limitation, Common Stock at its fair
               market value on the date of exercise.

     (c)  Term of Option. No Stock Option granted pursuant to this Plan will in
          --------------                                                       
          any event be exercisable after the expiration of ten (10) years from
          the date such Option is granted. Subject to the foregoing and other
          applicable provisions of this Plan, the term of each Option will be
          determined by the Committee in its discretion.

     (d)  Manner of Exercise: Rights as Shareholder. An Option will be deemed to
          -----------------------------------------                             
          be exercised when written notice of exercise has been given to the
          Company in accordance with the terms of the Option by the person
          entitled to exercise the Option, together with full payment for the
          shares of Common Stock subject to such notice.

     (e)  Death of Optionee. Unless otherwise provided in an Optionee's written
          -----------------                                                    
          agreement pursuant to this Plan, in the event of the death of an
          Optionee who at the time of his or her death was an Employee and who
          had been in Continuous Status as an Employee since the date of grant
          of the Option, the Option will (unless the Committee determines
          otherwise) terminate on the earlier of (i) one (1) year after the date
          of death of the Optionee, or (ii) the expiration date otherwise
          provided in the Option agreement, except that in no event will any
          Nonqualified Stock Option expire before the end of the ninety (90) day
          period immediately following the Optionee's death. The Option rights
          will be exercisable at any time prior to such termination by the
          Optionee's estate, or by such person or persons who have acquired the
          right to exercise the Option by bequest or by inheritance or by reason
          of the death of the Optionee.

     (f)  Disability of Optionee. Unless otherwise provided in an Optionee's
          ----------------------                                            
          written agreement pursuant to this Plan, if an Optionee's status as an
          Employee is terminated at any time during the Option period by reason
          of a disability (within the meaning of Section 22(e)(3) of the
          Internal Revenue Code or any shareholder agreement between Employer
          and Employee), and if such Optionee had been in Continuous Status as
          an Employee at all times between the date of grant of the Option and
          the termination of his or her status as an Employee, his or her Option
          will terminate on the earlier of (i) one (1) year after the date of
          termination of his or her status as an Employee, or (ii) the
          expiration date otherwise provided in his or her Option agreement. The
          Option will be exercisable by the Optionee at any time prior to such
          termination date.

     (g)  Termination of Status as an Employee.
          ------------------------------------ 

          (1)  Unless otherwise provided in an Optionee's written agreement
               pursuant to the Plan, if an Optionee's status as an Employee is
               terminated at any time after the grant of his or her Option for
               any reason other than death, disability, or termination by reason
               of fraud or willful misconduct, as provided in subparagraph
               3(g)(2) below, his or her Option will terminate on the earlier of
               (i) the same day of the third month after the date of termination
               of his or her status as an Employee, or (ii) the expiration date
               otherwise provided in his or her Option agreement. The Option
               will be exercisable by the Optionee at any time prior to such
               termination date, but only to the extent that it was exercisable
               by the Optionee on the date of termination of employment.

          (2)  Unless otherwise provided in an Optionee's written agreement
               pursuant to the Plan, if an Optionee's status as an Employee is
               terminated at any time after the grant of his or her Option by
               reason of fraud or willful misconduct, then his or her Option
               will terminate on the date of termination of his or her status as
               an Employee.

     (h)  Non-Transferability of Options. An Option may not be sold, pledged,
          ------------------------------                                     
          assigned, transferred, or disposed of in any manner other than by will
          or by the laws of descent or distribution, and may be exercised,
          during the lifetime of the Optionee, only by the Optionee.

     (i)  Date of Grant of Option. The date of grant of an Option will, for all
          -----------------------                                              
          purposes, be the date on which the Committee makes the determination
          granting such Option. Such date of grant will be specified in the
          Option agreement.

     (j)  Conditions On Issuance of Shares.
          -------------------------------- 

          (1)  Shares of Common Stock will not be issued with respect to an
               Option granted under this Plan unless the exercise of such Option
               and the issuance and delivery of such Shares pursuant thereto
               will comply with all relevant provisions of law, including,
               without limitation, the Securities Act of 1933, as amended, the
               Securities Exchange Act of 1934, as amended, or applicable state
               securities statutes or other jurisdictions, the rules and
               regulations promulgated under all such statutes, and the
               requirements of any stock exchange on which the Common Stock may
               then be listed, and will be further subject to the approval of
               counsel for the Company with respect to such compliance.

          (2)  As a condition to the exercise of an Option, the Company may
               require the person exercising such Option to represent and
               warrant at the time of exercise that the shares of Common Stock
               are being purchased only for investment and without any present
               intention to sell or distribute such Common Stock if, in the
               opinion of counsel for the Company, such a representation is
               required by any applicable law.

     (k)  Merger, Sale of Assets, etc. In the event of a proposed merger of the
          ---------------------------                                          
          Company with or into any other corporation, or in the event of a
          proposed sale of substantially all of the assets of the Company, or in
          the event of a proposed dissolution or liquidation of the Company, the
          Committee may, in the exercise of its sole discretion, terminate all
          outstanding Options as of a date fixed by the Committee. In such
          event, however, the Committee will notify each Optionee of such action
          in writing not less than ninety (90) days prior to the termination
          date fixed by the Committee, and each Optionee will have the right to
          exercise his or her Options prior to such termination date.

     (l)  Substitute Stock Options. In connection with the acquisition or
          ------------------------                                       
          proposed acquisition by the Company or any subsidiary, whether by
          merger, acquisition of stock or assets, or other reorganization
          transaction, of a business any employees of which have been granted
          stock options, the Committee is authorized to issue, in substitution
          of any such unexercised stock option, a new Option under this Plan
          that confers on the Optionee substantially the same benefits as the
          old option; provided, however, that the issuance of any new Incentive
          Stock Option for an old incentive stock option will satisfy the
          requirements of Section 425 (a) of the Internal Revenue Code.

     (m)  Tax Compliance. The Employer, in its sole discretion, may take any
          --------------                                                    
          actions reasonably believed by it to be required to comply with any
          local, state, or federal tax laws relating to the reporting or
          withholding of taxes attributable to the grant or exercise of any
          Option or the disposition of any shares of Common Stock issued on
          exercise of an Option, including, but not limited to (i) withholding
          from any Optionee exercising an Option a number of shares of Common
          Stock having a fair market value equal to the amount required to be
          withheld by the Employer under applicable tax laws, and (ii)
          withholding from any form of compensation or other amount due an
          Optionee or holder of shares of Common Stock issued on exercise of an
          Option any amount required to be withheld by the Employer under
          applicable tax laws. Withholding or reporting will be considered
          required for purposes of this subparagraph if any tax deduction or
          other favorable tax treatment available to Employer is conditioned on
          such reporting or withholding.

     (n)  Other Provisions. Option agreements executed pursuant to this Plan may
          ----------------                                                      
          contain such other provisions as the Committee will deem advisable;
          provided, in the case of Incentive Stock Options, that the provisions
          are not inconsistent with the provisions of Section 422 (a) of the
          Internal Revenue Code or with any of the other terms and conditions of
          this Plan.

3  RESTRICTED STOCK AWARD PROVISIONS

3.1   Restricted Stock Awards

     Common Stock of the Company may be awarded to an eligible Employee in the
     form of a Restricted Stock Award pursuant to the provisions and subject to
     the limitations of this Part III.

3.2   Eligibility for Awards

     Awards may be granted only to Employees whom the Committee, in its
     discretion, determines to be key Employees of the Company, a parent, or a
     subsidiary. The granting of Awards will be entirely discretionary with the
     Committee, and the adoption of this Plan will not confer on any Employee
     any right to receive any Awards unless and until such Awards are granted by
     the Committee. Neither the adoption of this Plan nor the granting of any
     Awards will confer on any Employee any right with respect to continuation
     of employment, nor will the same interfere in any way with his or her right
     (or with the right of the Employer) to terminate his or her employment at
     any time.

3.3  Terms and Conditions of Awards

     All Awards granted pursuant to this Plan must be authorized by the
     Committee, and must be documented in written agreements in such form as the
     Committee will from time to time approve, which agreements will comply with
     and be subject to all of the following terms and conditions:

     (a)  Shares Subject to Award. The shares of Common Stock subject to
          ------------------------                                      
          Restricted Stock Awards are as stated in Section 3 of Part I.

     (b)  Escrow. Stock certificates evidencing shares of Common Stock granted
          -------                                                             
          as a Restricted Stock Award will be issued in the name of the Grantee
          and deposited in escrow with an escrow service chosen by the Committee
          (the "Escrow Agent") to be held by the Escrow Agent subject to the
          terms hereof and subject to delivery to the Grantee or redelivery to
          the Escrow Agent in accordance with the terms and provisions of this
          Part III. By acceptance of an Award, the Grantee grants an irrevocable
          power of attorney to the Escrow Agent to transfer and deliver such
          Common Stock and stock certificates evidencing the same in accordance
          with the terms and provisions hereof and the directions of the
          Committee given pursuant to this Plan.

     (c)  Dividends and Voting Rights. During the period while the stock
          ----------------------------                                  
          certificates evidencing restricted stock are held in escrow as
          provided in this Plan, all dividends payable with respect to such
          stock will be paid by the Escrow Agent directly to the Grantee named
          therein and such Grantee will be entitled to exercise all voting
          rights with respect to such stock, all in the same manner and to the
          full extent as though such stock were held by the Grantee free of the
          escrow.

     (d)  Escrow Stock not Transferable. No transfer or other disposition of
          ------------------------------                                    
          Common Stock held in escrow under this Plan may be made by the Grantee
          as long as such stock is held under and remains subject to the escrow.

     (e)  Release of Stock from Escrow. Common Stock held in escrow pursuant to
          -----------------------------                                        
          the provisions of this Part III will be released from such escrow by
          the delivery of the stock certificate evidencing such shares to the
          Grantee (or, in the case of death or disability of the Grantee, to the
          Grantee's estate or legal guardian) at:

          (1)  The completion by the Grantee of such number of years or other
               periods of Continuous Status as an Employee measured from the
               date of the Award as the Committee will determine;

          (2)  The death of the Grantee;

                                       7
<PAGE>
 
          (3)  The determination by the Committee, acting in its sole
               discretion, to authorize the release of such stock to the Grantee
               on the occurrence of any event that the Committee determines to
               warrant such release; or

          (4)  The occurrence of a change in control of the Company. The term
               "control" will refer to the acquisition of twenty percent (20%)
               or more of the voting securities of the Company by any person or
               by persons acting as a group within the meaning of Section 13(d)
               of the Securities Exchange Act of 1934; provided, however, that,
               for the purposes of this subparagraph, no change in control will
               be deemed to have occurred if prior to the acquisition of, or
               offer to acquire, twenty percent (20%) or more of the voting
               securities of the Company, the full Board of Directors will have
               adopted by not less than a two-thirds vote a resolution
               specifically approving such acquisition or offer. For purposes of
               this subparagraph, the term "person" refers to an individual or a
               corporation, partnership, trust, association, joint venture,
               pool, syndicate, sole proprietorship, unincorporated
               organization, or any other form of entity not specifically listed
               herein.

     (f)  Termination of Employment. If Grantee ceases to be an Employee during
          -------------------------                                            
          the period that any Common Stock is held in escrow hereunder for the
          Grantee's account, other than by reason of death, normal retirement,
          or approved early retirement (and such Common Stock is not then
          subject to release under items (1), (2), or (4) of Section 3 (e)
          above), such stock will be forfeited to the Company and all rights of
          the Grantee with respect thereto terminated, unless, in the case of
          termination by act of the Company, the Committee, within thirty (30)
          days following such termination, authorizes the release of such Common
          Stock to such Grantee under the authority granted to it by item (3) of
          Section 3 above. On the expiration of such 30-day period without
          action by the Committee to release such Common Stock to the Grantee,
          the Common Stock will be deemed forfeited and the stock certificates
          evidencing the same will be redelivered to the Company, whereupon they
          will be canceled and retired.

                            SYMBOLOGIC CORPORATION
                    NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN


1     GENERAL PROVISIONS

1.1   Purpose of the Plan

      The purpose of the Symbologic Corporation Non-Employee Director Stock
      Option Plan (the "Plan") is to attract and retain the services of
      experienced and knowledgeable non-employee directors of Symbologic
      Corporation (the "Company") and to provide an incentive for such directors
      to increase their proprietary interest in the Company's long-term success.

1.2   Shares Subject to the Plan

1.2.1 Total Shares Available.
      -----------------------

      (a) The number of shares that may be issued and sold pursuant to options
          granted under this Plan will not, in the aggregate, exceed two
          hundred thousand (200,000) shares of the common stock of the Company
          (the "Shares").

      (b) Common stock issued under this Plan may be either authorized and
          unissued shares or shares issued and thereafter acquired by the
          Company. If any options granted under this Plan will, for any reason,
          expire without having been exercised in full, the common stock not
          purchased under such options, or so forfeited, will be available again
          for the purposes of this Plan.

1.2.2 Adjustments to Shares Available. The number of shares of common stock
      --------------------------------                                     
      covered by each outstanding option, the number of shares of common stock
      available for grant of additional options, and the price per share of
      common stock specified in each outstanding option, will be proportionately
      adjusted for any increase or decrease in the number of issued shares of
      common stock resulting from any stock split or other subdivision or
      consolidation of shares, the payment of any stock dividend (but only on
      the common stock), or any other increase or decrease in the number of such
      shares of common stock effected without receipt of consideration by the
      Company; provided, however, that conversion of any convertible securities
      of the Company will not be deemed to have been "effected without receipt
      of consideration." Such adjustment will be made by the Board of Directors,
      whose determination in that respect will be final, binding, and
      conclusive.

1.3   Administration of the Plan

      This Plan shall be administered by the Board of Directors of the Company
      (the "Board"), or, in the event the Board shall appoint and/or authorize a
      Compensation Committee to the administer this Plan, by such committee.
      Subject to the terms of this Plan, the Board shall have the power to
      construe the provisions of this Plan, to determine all questions arising
      thereunder and to adopt and amend such rules and regulations for the
      administration of this Plan as it may deem desirable.

      shareholder approval of this Plan as set forth below. Unless sooner
      terminated as provided below, this Plan will terminate on the tenth
      anniversary of its effective date. Options may be granted at any time
      after the effective date and prior to the date of termination of this
      Plan.

1.4.2 Amendment or Early Termination. The Board may amend, terminate or suspend
      ------------------------------                                           
      this Plan at any time, in its sole and absolute discretion; provided,
      however, that without the approval of the shareholders no amendment shall
      (1) increase the number of Shares subject to the option; (2) reduce the
      option price below 100% of the fair market value of the Shares subject to
      the option at the time the option was granted; (3) increase

                                       1

      beyond 5,000 the number of Shares for which options may be granted to each
      Director in a calendar year; or (4) change the timing with respect to
      which such options are granted.

      subsidiary ("Director") shall receive annually an option to acquire 5,000
      Shares under this Plan concurrent with the annual election of Directors by
      the shareholders of the Company. Each former Director of the Company
      during the period prior to the adoption of this Plan who was not an
      employee of the Company while serving on the Board shall receive an option
      to acquire 5,000 Shares under this Plan for each year of service as a

          ----------------

          behalf of the Company and by the Director to whom such option is
          granted (the "Optionee"). Each Agreement shall comply with and be
          subject to the terms and conditions of this Plan and shall
          conclusively evidence by the Optionee's signature thereon that it is
          the intent of the Optionee to continue to serve as a Director of the
          Company for the remainder of the year in which the option was granted,
          except in the case of an Optionee who is a former Director. The
          Agreement may contain such other terms, provisions and conditions not
          inconsistent with this Plan as may be determined by the Board.

     (b)  Option Exercise Price. The option exercise price for the option

          granted under this Plan shall be the fair market value of the Shares
          covered by the option at the time the option is granted. As described
          in Section 2.2, options granted under this Plan are considered granted
          on the date of the corresponding annual election of Directors by the
          shareholders of the Company, except for options granted to former
          Directors, which shall be considered granted on the date this Plan is
          adopted by the shareholders of the Company.

     (c)  Vesting of Options. Each option granted under this Plan shall become
          ------------------                                                  
          exercisable, but not for any fractional shares or for less than 100
          shares, one (1) year from the date of grant of the option. Each option
          granted under this Plan shall become fully exercisable upon the
          occurrence of the first of the following events:

          (1)  the Optionee is terminated as a Director by reason of death or
               disability; or

          (2)  a change in control occurs, as defined by one or more of the
               following events: (i) a person or entity acquires or otherwise

               Company's outstanding common stock; or (ii) the merger of the
               Company into any entity, fifty percent (50%) or more of the

               replacement of incumbent Directors or election of newly elected
               Directors constituting a majority of the Board of Directors of
               the Company where such replacement or election has not been
               unanimously supported by the Board of Directors of the Company;
               or (iv) the Securities and Exchange Commission declares effective
               a registration statement of the Company filed pursuant to the
               Securities Act of 1933, other than a registration on Form S-8
               respecting any employee or director stock plan.

      (d) Manner of Exercise of Option. No option granted under this Plan may be
          ----------------------------                                          
          exercised until a corresponding Agreement (as described in Section
          2.3(a)) has been executed by the Company and the Director to whom the
          option was granted. Any option may be exercised by giving written
          notice, signed by the Optionee, to the Company stating the number of
          Shares with respect to which the option is being exercised,
          accompanied by payment in full for such Shares, which payment may be
          in cash or in shares of common stock of the Company already owned by
          the person or persons exercising the option, valued at fair market
          value at the time of the exercise, or partly in cash and partly in
          such shares.

      (e) Term of Options. Each option shall expire not more than ten (10) years
          ---------------

          pursuant to Section 2.3(h).

      (f) Transferability. An option granted pursuant to this Plan may not be
          ---------------                                                    
          sold, pledged, assigned, hypothecated, transferred, or disposed of in
          any manner other than by will or by the laws of descent or
          distribution, and may be exercised, during the lifetime of the
          Optionee, only by the Optionee.

      (g) Participant's or Successor's Rights as Shareholders. Neither the
          ---------------------------------------------------             
          recipient of an option under this Plan nor his or her successor(s) in
          interest shall have any rights as a shareholder of the Company with
          respect to any Shares subject to an option granted to such person
          until such person becomes a holder of record of such Shares.

      (h) Termination of Status as a Director.
          ----------------------------------- 

          (1)  Unless otherwise provided in the Optionee's Agreement, if the
               Optionee's status as a Director is terminated at any time after
               the grant of the option for any reason other than death,
               disability, or termination by reason of fraud or willful
               misconduct, the option will terminate on the earlier of (i) one
               (1) year after the date the Optionee ceases to be a Director, or
               (ii) the expiration date otherwise provided in the Agreement. The
               option will be exercisable by the Optionee at any time prior to
               such termination date, but only to the extent that it was
               exercisable by the Optionee on the date of termination of as a
               Director.

          (2)  Unless otherwise provided in the Optionee's Agreement, in the

               the Optionee, or (ii) the expiration date otherwise provided in
               the Agreement, except that in no event will any option expire
               before the end of the ninety (90) day period immediately
               following the Optionee's death. The option rights will be
               exercisable at any time prior to such termination by the
               Optionee's estate, or by such person or persons who have acquired
               the right to exercise the option by bequest or by inheritance or
               by reason of the death of the Optionee.

          (3)  Unless otherwise provided in the Optionee's Agreement, if the
               Optionee's status as a Director is terminated at any time by
               reason of a disability (within the meaning of Section 22(e)(3) of
               the Internal Revenue Code), the option will terminate on the
               earlier of (i) one (1) year after the date of the termination of
               the Optionee's status as a Director, or (ii) the expiration date
               otherwise provided in the Agreement. The option will be
               exercisable by the Optionee at any time prior to such termination
               date.

          (4)  If the Optionee's status as a Director is terminated at any time
               after the grant of the option by reason of fraud or willful
               misconduct, then the option will terminate on the date of the
               termination of the Optionee's status as a Director.

      (i) Conditions On Issuance of Shares.
          -------------------------------- 

          (1)  Shares of common stock will not be issued with respect to an
               option granted under this Plan unless the exercise of such option
               and the issuance and delivery of such Shares pursuant thereto
               will comply with all relevant provisions of law, including,
               without limitation, the Securities Act of 1933, as amended, the
               Securities Exchange Act of 1934, as amended, or applicable state
               securities statutes or other jurisdictions, the rules and
               regulations promulgated under all such statutes, and the
               requirements of any stock exchange on which the common stock may
               then be listed, and will be further subject to the approval of
               counsel for the Company with respect to such compliance.

          (2)  As a condition to the exercise of an option, the Company may
               require the person exercising such option to represent and
               warrant at the time of exercise that the shares of common stock
               are being purchased only for investment and without any present
               intention to sell or distribute such common stock if, in the
               opinion of counsel for the Company, such a representation is
               required by any applicable law.

      (j) Tax Compliance. The Company, in its sole discretion, may take any
          --------------                                                   
          actions reasonably believed by it to be required to comply with any
          local, state, or federal tax laws relating to the reporting or
          withholding of taxes attributable to the grant or exercise of any
          option or the disposition of any shares of common stock issued on
          exercise of an option, including, but not limited to (i) withholding
          from any Optionee exercising an option a number of shares of common
          stock having a fair market value equal to the amount required to be
          withheld by the Company under applicable tax laws, and (ii)
          withholding from any form of compensation or other amount due the
          Optionee or holder of shares of common stock issued on exercise of an
          option any amount required to be withheld by the Company under
          applicable tax laws. Withholding or reporting will be considered
          required for purposes of this subparagraph if any tax deduction or
          other favorable tax treatment available to Company is conditioned on
          such reporting or withholding.

           After 1 year                                               25%   
           After 2 years                                              50%   
           After 3 years                                              75%

</TABLE>

     To the extent that the right to purchase shares has accrued thereunder, an
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>
 
may not be exercised as to less than 100 shares at any one time (or the lesser
number of remaining shares covered by the Option).

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, except that the Plan Administrator may, either at the time
the Option is granted or at any time before it is exercised and subject to such
limitations as the Plan Administrator may determine, authorize payment in cash
and/or one or more of the following alternative forms:  (i) 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; (ii) a promissory note authorized pursuant to
Section 11 of the Plan; (iii) if the Common Stock is publicly traded, delivery
of a properly executed exercise notice, together with irrevocable instructions,
to (a) 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 (b) 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; or (iv) 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:  (i) within three years if
the termination of the Holder's employment or services are coincident with
Disability, (ii) within three months if the termination of the Holder's
employment services is coincident with Retirement or Early Retirement at the
Company's request or (iii) 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 entitled thereto at any time or from time
to time within

                                      -8-
<PAGE>
 
one year after the date of death, but in no event later than the remaining term
of the Option. 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. Unless the Plan Administrator determines otherwise, a leave of
absence approved in accordance with Company procedures shall not be considered a
termination of employment or services, except that with respect to Incentive
Stock Options such leave of absence shall be subject to any requirements of
Section 422 of the Code.

                 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 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 Participant 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 a Participant owns 10% or more 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.

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 of the Plan, "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

     An Option designated as an Incentive Stock Option must be exercised within
three months after termination of employment for reasons other than death to
qualify for Incentive Stock Option tax treatment, except that in the case of
termination of employment due to Disability, such Option must be exercised
within one year after such termination.

8.6  Taxation of Incentive Stock Option

     In order to obtain certain tax benefits afforded to Incentive Stock Options
under Section 422 of the Code, the Participant must hold the shares issued upon
the exercise of an Incentive Stock Option for two years after the date of grant
of the Incentive Stock Option and one year from the date of exercise.  A
Participant may be subject to the alternative minimum tax at the time of
exercise of an Incentive Stock Option.  The Committee may require a Participant
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.

                     SECTION 9.  STOCK APPRECIATION RIGHTS

9.1  Grant of Stock Appreciation Rights

     The Plan Administrator may grant a Stock Appreciation Right separately or
in tandem with a related Option.

9.2  Tandem Stock Appreciation Rights

     A Stock Appreciation Right granted in tandem with a related Option will
give the Holder the right to surrender to the Company all or a portion of the
related Option and to receive an appreciation distribution (in shares of Common
Stock or cash or any combination of shares and cash, as the Plan Administrator
shall determine at any time) in an amount equal to the excess of the Fair Market
Value for the Window Period during which the Stock Appreciation Right is
exercised over the exercise price per share of the right, which shall be the
same as the exercise price of the related Option, except that if the right is
exercised during a Window Period, the amount will be equal to the excess of the
Window Period Fair Market Value for the Window Period during which the Stock
Appreciation Right is exercised over the exercise price per share of the right.
A tandem Stock Appreciation Right will have the same other terms and provisions
as the related Option.  Upon and to the extent a tandem Stock Appreciation Right
is exercised, the related Option will terminate.

9.3  Stand-Alone Stock Appreciation Rights

     A Stock Appreciation Right granted separately and not in tandem with an
Option will give the Holder the right to receive an appreciation distribution in
an amount equal to the excess of the Fair Market Value for the date the Stock
Appreciation Right is exercised over the exercise price per share of the right,
except that if the right is exercised during a Window

                                      -10-
<PAGE>
 
Period, the amount will be equal to the excess of the Window Period Fair Market
Value for the Window Period during which the right is exercised over the
exercise price per share of the right. A stand-alone Stock Appreciation Right
will have such terms as the Plan Administrator may determine, except that the
exercise price per share of the right must be at least equal to 85% of the Fair
Market Value on the Grant Date and the term of the right, if not otherwise
established by the Plan Administrator, shall be 10 years from the Grant Date.

9.4  Exercise of Stock Appreciation Rights

     Unless otherwise provided by the Plan Administrator in the instrument that
evidences the Stock Appreciation Right, the provisions of Section 7.6 of the
Plan relating to the termination of a Holder's employment or services shall
apply equally, to the extent applicable, to the Holder of a Stock Appreciation
Right.  Stock Appreciation Rights held by Participants who are subject to
Section 16 of the Exchange Act may be exercised solely in accordance with the
requirements for compliance with Rule 16b-3 under the Exchange Act.

                           SECTION 10.  STOCK AWARDS

10.1  Grant of Stock Awards

     The Plan Administrator is authorized to make Awards of Common Stock to
Participants on such terms and conditions and subject to such restrictions, if
any (whether based on performance standards, periods of service or otherwise),
as the Plan Administrator shall determine, 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.

10.2  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 deliver, 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, a stock certificate for the
appropriate number of shares of Common Stock.

10.3  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

                                      -11-
<PAGE>
 
any Restricted Stock under such circumstances and subject to such terms and
conditions as the Plan Administrator shall deem appropriate.

          SECTION 11.  LOANS, LOAN GUARANTEES AND INSTALLMENT PAYMENTS

     To assist a Holder (including a Holder who is an officer or director of the
Company) in acquiring shares of Common Stock pursuant to an Award granted under
the Plan, the Plan Administrator may authorize, either at the Grant Date or at
any time before the acquisition of Common Stock pursuant to the Award, (i) the
extension of a loan to the Holder by the Company, (ii) the payment by the Holder
of the purchase price, if any, of the Common Stock in installments, or (iii) the
guarantee by the Company of a loan obtained by the grantee from a third party.
The terms of any loans, installment payments or guarantees, including the
interest rate and terms of repayment, will be subject to the Plan
Administrator's discretion.  Loans, installment payments and 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 12.  ASSIGNABILITY

     No Option or Stock Appreciation Right granted under the Plan may be
assigned or transferred by the Holder other than by will or by the 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 Rule 16b-3 under the Exchange Act and 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.

                            SECTION 13.  ADJUSTMENTS

13.1  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 (i)
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 (ii) 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,
in its sole discretion, shall make such equitable adjustments as it shall deem
appropriate in the circumstances in (a) the maximum number of and class of
securities subject to the Plan as set forth in Section 4.1 of

                                      -12-
<PAGE>
 
the Plan and (b) the number and class 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.

13.2  Corporate Transaction

     Except as otherwise provided in the instrument that evidences the Award, in
the event of any Corporate Transaction, each Option, Stock Appreciation Right or
Stock 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, except that such acceleration
will not occur if in the opinion of the Company's accountants it would render
unavailable "pooling of interest" accounting for a Corporate Transaction that
would otherwise qualify for such accounting treatment or to the extent that the
Board determines not to allow for acceleration of vesting.  Notwithstanding the
foregoing, no Incentive Stock Option shall become exercisable pursuant to this
Section 13.2 without the Holder's consent, if the result would be to cause such
Option not to be treated as an Incentive Stock Option (whether by reason of the
annual limitation described in Section 8.1 of the Plan or otherwise).

13.3  Further Adjustment of Awards

     Without limiting the preceding Section 13.2 of the Plan, 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 Participants,
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, payment or settlement or lifting
restrictions, differing methods for calculating payments or settlements,
alternate forms and amounts of payments and settlements and other modifications,
and the Plan Administrator may take such actions with respect to all
Participants, to certain categories of Participants or only to individual
Participants.  The Plan Administrator may take such actions 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.

13.4  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.

                       SECTION 14.  WITHHOLDING OF TAXES

     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, exercise, payment or settlement of any Award.  In such instances, the
Plan Administrator may, in its discretion and subject to the Plan and applicable
law, 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.

                 SECTION 15.  AMENDMENT AND TERMINATION OF PLAN

15.1  Amendment of Plan

     The Plan may be amended by the shareholders of the Company.  The Board may
also amend the Plan in such respects as it shall deem advisable; however, to the
extent required for compliance with Rule 16b-3 under the Exchange Act, Section
422 of the Code or any applicable law or regulation, shareholder approval will
be required for any amendment that will (i) increase the total number of shares
as to which Options may be granted or which may be used in payment of Stock
Appreciation Rights under the Plan or that may be issued as Restricted Stock,
(ii) materially modify the class of persons eligible to receive Awards, (iii)
materially increase the benefits accruing to Participants under the Plan, or
(iv) otherwise require shareholder approval under any applicable law or
regulation.

15.2  Termination of Plan

     The Company's shareholders or the Board may suspend or terminate the Plan
at any time.  The Plan will have no fixed expiration date; provided, however,
that no Incentive Stock Options may be granted more than 10 years after the
Plan's effective date.

15.3  Consent of Holder

     The amendment or termination of the Plan shall not, without the consent of
the Holder of any Award under the Plan, alter or impair any rights or
obligations under any Award theretofore granted under the Plan.

16.2  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 17.  MARKET STAND-OFF

     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
Participant 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 this Plan without the
prior written consent of the Company or its underwriters.  Such limitations
shall be in effect for such period of time from and after the effective date of
the final prospectus for the offering as may be requested by the Company or such
underwriters; provided, however, that in no event shall such period exceed one
hundred eighty (180) days.  The limitations of this paragraph shall in all
events terminate two (2) years after the effective date of the Company's initial
public offering.

     Participant shall be subject to the market stand-off provisions of this
paragraph provided and only if the officers and directors of the Company are
also subject to similar arrangements with respect to shares of the Company held
by them (other than any shares to be involved in the offering).

     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 paragraph, to the same extent the purchased shares are at
such time covered by such provisions.

                                      -15-
<PAGE>
 
     In order to enforce the limitations of this Section, the Company may impose
stop-transfer instructions with respect to the purchased shares until the end of
the applicable stand-off period.

                              SECTION 18.  GENERAL

18.1  Notification

     The Plan Administrator shall promptly notify a Participant of an Award, and
a written grant shall promptly be executed and delivered by or on behalf of the
Company.

18.2  Continued Employment or Services; Rights in Awards

     Neither the Plan, participation in the Plan as a Participant nor any action
of the Plan Administrator taken under the Plan shall be construed as giving any
Participant or employee of the Company any right to be retained in the employ of
the Company or limit the Company's right to terminate the employment or services
of the Participant.

18.3  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 Common Stock, security or
interest in a security paid or issued under, or created by, the Plan.  The
Company may issue certificates for shares with such legends and subject to such
restrictions on 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.

18.4  No Rights as a Shareholder

     No Option, or Stock Appreciation Right shall entitle the Holder to any
dividend (except to the extent provided in an Award of Dividend Equivalent
Rights), 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 Awards, free
of all applicable restrictions.

18.5  Compliance With Laws and Regulations

     It is the Company's intention that, so long as any of the Company's equity
securities are registered pursuant to Section 12(b) or 12(g) of the Exchange
Act, the Plan shall comply in all respects with Rule 16b-3 under the Exchange
Act and, if any Plan provision is later found not to be in compliance with such
Rule, the provision shall be deemed null and void, and in all events the Plan
shall be construed in favor of its meeting the requirements of Rule 16b-3.
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 Participants who are officers or directors
subject to Section 16 of the Exchange

                                      -16-
<PAGE>
 
Act without so restricting, limiting or conditioning the Plan with respect to
other Participants. 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.

18.6  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 payable to any Participant, and no
Participant shall have any rights that are greater than those of a general
unsecured creditor of the Company.

18.7  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 19.  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 or, if earlier, and to the extent required for
compliance with Rule 16b-3 under the Exchange Act, at the next annual meeting of
the Company's shareholders after adoption of the Plan by the Board.

     Originally adopted by the Board on December 27, 1995, and approved by the
Company's shareholders on January 16, 1996; amended and restated by the Board on
March 12, 1996; amended by the Board on January 24, 1997; amended by the Board

          Stock issued or issuable pursuant to the exercise of an Option or
          Stock Appreciation Right granted under this Plan or pursuant to a
          Stock Award under the Plan, then those shares, including any shares of

          discretion, at the Fair Market Value of such shares on the date of

thereof as the Plan Administrator shall determine.  Any Award settlement,
including payment deferrals, may be subject to such conditions, restrictions and
contingencies as the Plan Administrator shall determine.  The Plan Administrator
may permit or require the deferral of any Award payment, subject to such rules
and procedures as it may establish, which may include provisions for the payment
or crediting of interest, or dividend equivalents, including converting such
credits into deferred stock equivalents.  The Plan Administrator may at any time
offer to buy out, for a payment in cash or Common Stock, an Award previously

     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 may be required for
compliance with Rule 16b-3 under the Exchange Act, and the persons holding such
awards shall be deemed to be Participants.

                         SECTION 7.  AWARDS OF OPTIONS

7.1  Grant of Options

     The Plan Administrator is authorized under the Plan, in its sole
discretion, to issue Options as Incentive Stock Options or as Nonqualified Stock
Options, which shall be appropriately designated.

                                       5
<PAGE>
 
7.2  Option Exercise Price

     The exercise price for shares purchased under an Option shall be as
determined by the Plan Administrator, but shall not be less than 100% of the
Fair Market Value of the Common Stock on the Grant Date with respect to
Incentive Stock Options and not less than 85% of the Fair Market Value of the
Common Stock on the Grant Date with respect to Nonqualified Stock Options. For
Incentive Stock Options granted to a more than 10% shareholder, the Option
exercise price shall be as specified in Section 8.2.

7.3  Term of Options

     The term of each Option (the "Option Term") shall be as established by the
Plan Administrator or, if not so established, shall be ten years from the Grant
Date.  For Incentive Stock Options, the maximum Option Term shall be as
specified in Sections 8.2 and 8.4.

7.4  Exercise of Options

     The Plan Administrator shall establish and set forth in each instrument
that evidences an Option the time at which, or the installments in which, the
Option shall vest and become exercisable, 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 shall vest and become exercisable
according to the following schedule, which may be waived or modified by the Plan
Administrator at any time:

<TABLE>
<CAPTION>

Employment or Service With the Company 
 or Its Related Corporations From the              Percent of Total Option

- -------------------------------------------------------------------------------

             After 1 year                                    25%

  Each additional one-month period of
continuous service completed thereafter               An additional 1/48
 
            After 4 years                                   100%
</TABLE>

     The Plan Administrator may adjust the vesting schedule of an Option held by
a Participant who works less than "full-time" as that term is defined by the
Plan Administrator.

     To the extent that an Option has vested and become exercisable, the Option
may be exercised from time to time by delivery to the Company of a written stock
option exercise agreement or notice, in a form and in accordance with procedures
established by the Plan Administrator, setting forth the number of shares with
respect to which the Option is being exercised, the restrictions imposed on the
shares purchased under such exercise agreement, if any, and such representations
and agreements as may be required by the Plan Administrator, accompanied by
payment in full as described in Section 7.5.  An Option may not be exercised as

                                       6
<PAGE>
 
to less than a reasonable number of shares at any one time, as determined by the
Plan Administrator.

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, in any combination of

     (a)  cash or check;

     (b)  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)
shares of Common Stock already owned by the Participant 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;

     (c)  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; or

     (d)  such other consideration as the Plan Administrator may permit.

     In addition, to assist a Participant (including a Participant 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, (i) the payment by a
Participant of a full-recourse promissory note, (ii) the payment by the
Participant of the purchase price, if any, of the Common Stock in installments,
or (iii) the guarantee by the Company of a loan obtained by the Participant from
a third party.  Subject to the foregoing, the Plan Administrator shall in its
sole discretion specify the terms of any loans, installment payments or loan
guarantees, including the interest rate and terms of and security for repayment.

7.6  Post-Termination Exercises

     The Plan Administrator shall establish and set forth in each instrument
that evidences an Option whether the Option shall continue to be exercisable,
and the terms and conditions of such exercise, if a Participant ceases to be
employed by, or to provide services to, the Company or its Related Corporations,
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
shall be 

                                       7
<PAGE>
 
exercisable according to the following terms and conditions, which may be waived
or modified by the Plan Administrator at any time:

     (a) Any portion of an Option that is not vested and exercisable on the date
of termination of the Participant's employment or service relationship (the
"Termination Date") shall expire on such date.

     (b) Any portion of an Option that is vested and exercisable on the
Termination Date shall expire upon the earliest to occur of

          (i)    the last day of the Option Term;

          (ii)   if the Participant's Termination Date occurs for reasons other
than Cause, death or Disability, the three-month anniversary of such Termination
Date; and

          (iii)  if the Participant's Termination Date occurs by reason of
Disability or death, the one-year anniversary of such Termination Date.

Notwithstanding the foregoing, if the Participant dies after the Termination
Date while the Option is otherwise exercisable, the portion of the Option that
is vested and exercisable on such Termination Date shall expire upon the earlier
to occur of (y) the last day of the Option Term and (z) the first anniversary of
the date of death, unless the Plan Administrator determines otherwise.

     Also notwithstanding the foregoing, in case of termination of the
Participant's employment or service relationship for Cause, the Option shall
automatically expire upon first notification to the Participant of such
termination, unless the Plan Administrator determines otherwise.  If a
Participant's employment or service relationship with the Company is suspended
pending an investigation of whether the Participant shall be terminated for
Cause, all the Participant's rights under any Option likewise shall be suspended
during the period of investigation.

     A Participant's transfer of employment or service relationship between or
among the Company and its Related Corporations, or a change in status from an
employee to a consultant, agent, advisor or independent contractor, shall not be
considered a termination of employment or service relationship for purposes of
this Section 7.  Employment or service relationship shall be deemed to continue
while the Participant is on a bona fide leave of absence, if such leave was
approved by the Company or a Related Corporation in writing and if continued
crediting of service for purposes of this Section 7 is expressly required by the
terms of such leave or by applicable law (as determined by the Company).  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
<PAGE>
 
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 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 Participant 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  More Than 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 more than 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

     Except as provided in Section 8.2, the Option Term shall not exceed 10
years.

8.5  Exercisability

     An Option designated as an Incentive Stock Option shall cease to qualify
for favorable tax treatment as an Incentive Stock Option to the extent it is
exercised (if permitted by the terms of the Option) (a) more than three months
after the Termination Date for reasons other than death or Disability, (b) more
than one year after the Termination Date by reason of Disability, or (c) after
the Participant has been on leave of absence for more than 90 days, unless the
Participant's reemployment rights are guaranteed by statute or contract.

     For purposes of this Section 8.5, Disability shall mean "disability" as
that term is defined for purposes of Section 422 of the Code.

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 Participant must hold the shares issued upon
the exercise of an Incentive Stock Option for two years after the Grant Date and
one year from the date of exercise.  A Participant may be subject to the
alternative minimum tax at the time of exercise of an Incentive 

                                       9
<PAGE>
 
Stock Option. The Participant shall 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 7.5 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 or
Awards denominated in units 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 the Stock Award
shall occur by reason of termination of the Participant's employment or service
relationship.

9.2  Issuance of Shares

     Upon the satisfaction of any terms, conditions and restrictions prescribed
in respect to a Stock Award, or upon the Participant'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
Participant or, in the case of the Participant's death, to the personal
representative of the Participant'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 Stock Award under such circumstances and
subject to such terms and conditions as the Plan Administrator shall deem
appropriate.

                           SECTION 10.  WITHHOLDING

     The Company may require the Participant 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 

                                       10
<PAGE>
 
sole discretion, permit the Participant to satisfy withholding obligations (up
to the minimum rate), 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
Participant an amount equal to such taxes. The Company may also deduct from any
Award any other amounts due from the Participant to the Company or a Related
Corporation.

                          SECTION 11.  ASSIGNABILITY

     Awards granted under the Plan and any interest therein may not be assigned,
pledged or transferred by the Participant and may not be made subject to
attachment or similar proceedings otherwise than by will or by the applicable
laws of descent and distribution, and, during the Participant's lifetime, such
Awards may be exercised only by the Participant.  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 Participant to designate a beneficiary who may exercise the
Award or receive compensation under the Award after the Participant'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 12.  ADJUSTMENTS

12.1  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.
Notwithstanding the foregoing, a dissolution or liquidation of the Company or a
Corporate Transaction shall not be governed by this Section 12.1 but shall be
governed by Sections 12.2 and 12.3, respectively.

12.2  Dissolution or Liquidation

     In the event of the proposed dissolution or liquidation of the Company, the
Plan Administrator shall notify each Participant as soon as practicable prior to
the effective date of such proposed transaction.  The Plan Administrator in its
discretion may permit a Participant to 

                                       11
<PAGE>
 
exercise an Option until ten days prior to such transaction with respect to all
vested and exercisable shares of Common Stock covered thereby and with respect
to such number of unvested shares as the Plan Administrator shall determine. In
addition, the Plan Administrator may provide that any forfeiture provision or
Company repurchase option applicable to any Award shall lapse as to such number
of shares as the Plan Administrator shall determine, contingent upon the
occurrence of the proposed dissolution or liquidation at the time and in the
manner contemplated. To the extent an Option has not been previously exercised,
the Option shall terminate automatically immediately prior to the consummation
of the proposed action. To the extent a forfeiture provision applicable to a
Stock Award has not been waived by the Plan Administrator, the Stock Award shall
be forfeited automatically immediately prior to the consummation of the proposed
action.

12.3  Corporate Transaction

     In the event of a Corporate Transaction, except as otherwise provided in
the instrument evidencing the Award, each outstanding Option shall be continued,
assumed or an equivalent option or right substituted by the surviving
corporation, the successor corporation or its parent corporation, as applicable
(the "Successor Corporation"). In the event that the Successor Corporation
refuses to continue, assume or substitute for the Option, the Participant shall
fully vest in and have the right to exercise the Option as to all of the shares
of Common Stock subject thereto, including shares as to which the Option would
not otherwise be vested or exercisable. If an Option becomes fully vested and
exercisable in lieu of assumption or substitution in the event of a Corporate
Transaction, the Plan Administrator shall notify the Participant in writing or
electronically that the Option shall be fully vested and exercisable for a
specified time period after the date of such notice, and the Option shall
terminate upon the expiration of such period, in each case conditioned on the
consummation of the Corporate Transaction. For the purposes of this Section
12.3, the Option shall be considered assumed if, following the Corporate
Transaction, the option or right confers the right to purchase or receive, for
each share of Common Stock subject to the Option, immediately prior to the
Corporate Transaction, the consideration (whether stock, cash, or other
securities or property) received in the merger or sale of assets by holders of
Common Stock for each share held on the effective date of the transaction (and
if holders were offered a choice of consideration, the type of consideration
chosen by the holders of a majority of the outstanding shares); provided,
however, that if such consideration received in the Corporate Transaction is not
solely common stock of the Successor Corporation, the Plan Administrator may,
with the consent of the Successor Corporation, provide for the consideration to
be received upon the exercise of the Option, for each share of Common Stock
subject thereto, to be solely common stock of the Successor Corporation equal in
fair market value to the per share consideration received by holders of Common
Stock in the Corporate Transaction. All Options shall terminate and cease to
remain outstanding immediately following the consummation of the Corporate
Transaction, except to the extent assumed by the Successor Corporation.

     In the event of a Corporate Transaction, the vesting of Shares subject to
Stock Awards shall accelerate, and the forfeiture provisions to which such
Shares are subject shall lapse, if and to the same extent that the vesting of
outstanding Options accelerates in connection with the Corporate Transaction.
If unvested Options are to be assumed, continued or substituted by a Successor
Corporation without acceleration upon the occurrence of a Corporate Transaction,
the 

                                       12
<PAGE>
 
forfeiture provisions to which such shares are subject will continue with
respect to shares of the Successor Corporation that may be issued in exchange
for such Shares.

12.4  Further Adjustment of Awards

     Subject to Sections 12.2 and 12.3, 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 the Participants, 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 Participants,
to certain categories of Participants or only to individual Participants.  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.

12.5  Limitations

     The grant of Awards 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 13.  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 of 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, any new, substituted or additional securities
distributed with respect to the purchased shares shall be immediately subject to
the provisions of this Section 13, to the same extent the purchased shares are
at such time covered by such provisions.

                                       13
<PAGE>
 
     In order to enforce the limitations of this Section 14, the Company may
impose stop-transfer instructions with respect to the purchased shares until the
end of the applicable standoff period.

                SECTION 14.  AMENDMENT AND TERMINATION OF PLAN

14.1  Amendment of Plan

     The Plan may be amended only by the Board in such respects as it shall deem
advisable; provided, however, that to the extent required for compliance with
Section 422 of the Code or any applicable law or regulation, shareholder
approval shall be required for any amendment that would (a) increase the total
number of shares available for issuance under the Plan, (b) modify the class of
persons eligible to receive Options, or (c) otherwise require shareholder
approval under any applicable law or regulation.  Any amendment made to the Plan
that would constitute a "modification" to Incentive Stock Options outstanding on
the date of such amendment shall not, without the consent of the Participant, be
applicable to such outstanding Incentive Stock Options but shall have
prospective effect only.

14.2  Termination of Plan

     The Board may suspend or terminate the Plan at any time.  Unless sooner
terminated as provided herein, the Plan shall terminate ten years after the
earlier of the Plan's adoption by the Board and approval by the shareholders.

14.3  Consent of Participant

     The amendment or termination of the Plan or the amendment of an outstanding
Award shall not, without the Participant's consent, impair or diminish any
rights or obligations under any Award theretofore granted to the Participant
under the Plan.  Any change or adjustment to an outstanding Incentive Stock
Option shall not, without the consent of the Participant, 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.  Notwithstanding
the foregoing, any adjustments made pursuant to Section 12 shall not be subject
to these restrictions.

                             SECTION 15.  GENERAL

15.1  Evidence of Awards

     Awards granted under the Plan shall be evidenced by a written instrument
that shall contain such terms, conditions, limitations and restrictions as the
Plan Administrator shall deem advisable and that are not inconsistent with the
Plan.

15.2  No Individual Rights

     Nothing in the Plan or any Award granted under the Plan shall be deemed to
constitute an employment contract or confer or be deemed to confer on any
Participant any right to continue in the employ of, or to continue any other
relationship with, the Company or any Related 

                                       14
<PAGE>
 
Corporation or limit in any way the right of the Company or any Related
Corporation to terminate a Participant's employment or other relationship at any
time, with or without Cause.

15.3  Registration

     Notwithstanding any other provision of the Plan, the Company shall have no
obligation to issue or deliver any shares of Common Stock under the Plan or make
any other distribution of benefits under the Plan unless such issuance, delivery
or distribution would comply with all applicable laws (including, without
limitation, the requirements of the Securities Act), and the applicable
requirements of any securities exchange or similar entity.

     The Company shall be under no obligation to any Participant 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 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.

     To the extent that the Plan or any instrument evidencing an Award provides
for issuance of stock certificates to reflect the issuance of shares of Common
Stock, the issuance may be effected on a noncertificated basis, to the extent
not prohibited by applicable law or the applicable rules of any stock exchange.

15.4  No Rights as a Shareholder

     No Option or Stock Award denominated in units shall entitle the Participant
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
Award.

15.5  Compliance With Laws and Regulations

     Notwithstanding anything in the Plan to the contrary, the Plan
Administrator, in its sole 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 or directors subject to Section 16 of the Exchange Act without so
restricting, limiting or conditioning the Plan with respect to other
Participants.  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.

15.6  Participants in Foreign Countries

     The Plan Administrator shall have the authority to adopt such
modifications, procedures and subplans as may be necessary or desirable to
comply with provisions of the laws of foreign countries in which the Company or
its Related Corporations may operate to assure the viability of the benefits

15.7  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 Participant, and no
Participant shall have any rights that are greater than those of a general
unsecured creditor of the Company.

15.8  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.

15.9  Choice of Law

     The Plan and all determinations made and actions taken pursuant hereto, to
the extent not otherwise governed by the laws of the United States, shall be
governed by the laws of the State of Washington without giving effect to
principles of conflicts of laws.

                          SECTION 16.  EFFECTIVE DATE

     The Effective Date is the date on which the Plan 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.

          3. RENT.  Lessee agrees to and shall pay to Lessor, the Monthly Rental

stated in Section 1(g) in advance on the first day of each calendar month during

such period.

          4. ACCEPTANCE OF PREMISES.  Except for those punchlist items scheduled
             ----------------------                                             
by Lessor and Lessee prior to the Lease Commencement Date, Lessee's occupancy of
the Premises shall be deemed to constitute acceptance of same and acknowledgment
by Lessee that Lessor has fully complied with its obligations hereunder to
construct and deliver to Lessee the Premises.  Lessor shall have the right to
enter the Premises to complete or repair any such unfinished items and entry by
Lessor, its agents, servants, employees, or contractors for such purpose shall

ready for occupancy at the commencement of the Lease Term, Lessor shall not be
liable for any damage caused thereby, nor shall this Lease become void or
voidable, but in such event, no Rental shall be payable by Lessee to Lessor for
any portion of the Lease Term until Lessor can deliver possession of Premises to
Lessee ready for occupancy by Lessee.  If the Commencement Date of the Lease
Term is delayed, the termination date will be extended by a like period of time.
If Lessee, with Lessor's permission, enters into possession of Premises prior to
commencement of the Lease Term, all of the terms and conditions of this Lease
shall apply during such prior period, including payment of Rent at the Monthly
Rate stated in Section 1(g).  The Premises shall be ready for occupancy on the
date the Lessor receives approval from the City of Seattle for occupancy of the
Premises.

          6. SECURITY DEPOSIT.  As security for the full and faithful
             ----------------                                        
performance of every covenant and condition of this Lease to be performed by
Lessee, Lessee has paid to Lessor the Security Deposit as specified in Section
1(h) hereof, receipt of which is hereby acknowledged. If Lessee shall default
with respect to any covenant or condition of this Lease, including but not
limited to the payment of Rent, Additional Rent, or any other payment due under
this Lease, Lessor may apply all or any part of the Security Deposit to the
payment of any sum in default or any other sum which Lessor may be required to
spend or incur by reason of Lessee's default or any other sum which Lessor may
in its reasonable discretion deem necessary to spend or incur by reason of
Lessee's default. In such event, Lessee shall, within five (5) days of written
demand therefore by Lessor, deposit with Lessor the amount so applied. If Lessee
shall have fully complied with all of the covenants and conditions of this
Lease, but not otherwise, the amount of the Security Deposit

                                       4
<PAGE>
 
then held by Lessor shall be repaid to Lessee (or, at Lessor's option, to the
last assignee of Lessee's interest hereunder) within thirty (30) days after the
expiration or sooner termination of this Lease.
          In the event of Lessee's default under this Lease, Lessor's right to
retain the Security Deposit shall be deemed to be in addition to any and all
other rights and remedies at law or in equity available to Lessor. Lessor shall
not be required to keep any Security Deposit separate from its general funds and
Lessee shall not be entitled to any interest thereon.

          7. USE.  Lessee shall use and occupy the Premises only for general
             ---                                                            
office purposes and for no other purposes without Lessor's prior written
consent. Lessee shall not do or permit anything to be done in or about the
Premises nor bring or keep anything therein which will in any way increase the
existing rate of or affect any fire or other insurance upon the Building or any
of its contents, or cause a cancellation of any insurance policy covering said
Building or any part thereof or any of its contents. Lessee shall not do or
permit anything to be done in or about the Premises which will in any way
obstruct or interfere with the rights of other tenants or occupants of the
Building or injure or annoy them or use or allow the Premises to be used for any
improper, immoral, unlawful, or objectionable purpose, nor shall Lessee cause,
maintain, or permit any nuisance in, on, or about the Premise. Lessee shall not
commit or suffer to be committed any waste in or upon the Premises.

          8. SERVICES AND UTILITIES.
             ---------------------- 

          (a) Standard Services. Lessor shall cause the Premises and the public
and Common Areas of the Building, such as lobbies, elevators, stairs, corridors,
and restrooms, to be maintained in reasonably good order and condition
consistent with the operation and maintenance of the Building as a first-class
office building in Seattle, except for damage occasioned by any act or omission
of Lessee or Lessee's officers, contractors, agents, invitees, licensees, or
employees, the repair of which damage shall be paid for by Lessee.

          From 7:00 a.m. to 6:00 p.m. on weekdays and from 7:00 a.m. to 1:00
p.m. on Saturday, excluding legal holidays ("Normal Business Hours"), Lessor
shall furnish the Premises with electricity for lighting and operation of
standard office machines, water, heat and air conditioning, and elevator
service.

          During all other hours, Lessor shall furnish such services, including
elevator service as reasonably required to provide access to the Premises,
except for heat and air conditioning. If requested by Lessee, Lessor shall
furnish heat and air conditioning at times other than Normal Business Hours and
the cost of such services as established by Lessor shall be paid by Lessee as
Additional Rent. Lessor shall also provide lamp replacement service for building
standard fluorescent light fixtures, toilet room supplies, window washing at
reasonable intervals, and customary building janitorial service. No janitorial
service shall be provided Saturdays, Sundays, or legal holidays. The costs of
any janitorial or other service provided or caused to be provided by Lessor to
Lessee which are in addition to the services ordinarily provided building
tenants shall be paid in the manner provided for payment of Rent in Section 3 of
this Lease.

          Lessor shall be obligated to provide the services and utilities as
outlined herein only so long as Lessee is not in default per Section 25 of this
Lease.

          (b) Interruption of Services.  Lessor shall not be liable for any
loss, injury, or damage to person or property caused by or resulting from any
variation, interruption, or failure of such services due to any cause
whatsoever, or from failure to make any repairs or perform any maintenance.  No
temporary interruption or failure of such services incident to the making of
repairs, alterations, or improvements, or due to accident, strike, or conditions
or events  beyond Lessor's reasonable control shall be deemed an eviction of
Lessee or relieve Lessee from any of Tenant's obligations hereunder.

          (c) Additional Services.  Lessee will not, without the written consent
of Lessor, use any apparatus or device in the Premises using current in excess
of 110 volts, except as may be provided in Exhibit A; nor connect with electric
current, except through existing electrical outlets in the Premises, or water
pipes, any apparatus or device, for the purposes of using electric current or
water.  If Lessee shall require water or electric current in excess of that
usually  furnished or supplied for use of the Premises as general office space,
Lessee shall first procure the consent of Lessor to the use thereof and Lessor
may cause a water meter or electric current meter to be installed in the
Premises, so as to measure the amount of water and electric current consumed for
any such other use.  The cost of any such meters and of installation,
maintenance, and repair thereof

                                       5
<PAGE>
 
shall be paid by the Lessee and Lessee agrees to pay to Lessor promptly upon
demand therefore by Lessor for all such water and electric current consumed as
shown by said meters, at the rates charged for such services by the City of
Seattle or the local public utility, as the case may be, furnishing the same,
plus any additional expense incurred in keeping account of the water and
electric current so consumed. Wherever heat generating machines or equipment are
used in the Premises which affect the temperature otherwise maintained by the
air conditioning systems, Lessor reserves the right to install supplementary air
conditioning units in the Premises and the cost thereof, including the cost of
installation, operation, and maintenance of any such supplementary equipment,
shall be paid by Lessee to Lessor upon demand by Lessor. Lessee shall obtain a
maintenance agreement at Lessee's sole cost and expense for routine and
preventative maintenance of said supplemental equipment.

             (10) "Pro Rata Share" shall be a proportion determined by using a
ratio, the numerator of which is the net rentable area of the Premises and the
denominator of which is the Net Rentable Area of the Building.

             (b) Base Amount.  For purposes of this Section, Operating Costs
                 -----------            
Base Amount shall be Lessee's Pro Rata Share of the Base Year Actual Operating
Costs adjusted per Section 9(g).

             (c) Additional Rent for Estimated Increases in Operating Costs.
                 ----------------------------------------------------------
Prior to the commencement of each Lease Year after the Base Year (1996), during
the Term hereof, Lessor shall furnish Lessee a written statement of the
Estimated Operating Costs Allocable to the Premises, for such Lease Year, and a
calculation of the Additional Rent as follows: One-twelfth (1/12) of the amount,
if any, by which such Estimated Operating Costs Allocable to the Premises
exceeds the Operating Costs Base Amount shall be Additional Rent payable by
Lessee as provided in Section 3 for each month during such Lease Year.

             (d) Actual Operating Costs. Approximately ninety (90) days after
                 ----------------------
the close of each Lease Year during the Term hereof for which an estimated
statement was delivered to Lessee pursuant to subsection (c), or as soon
thereafter as practicable, Lessor shall deliver to Lessee a written statement
setting forth the Actual Operating Costs Allocable to the Premises during the
preceding Lease Year. If such costs for any Lease Year exceed Estimated
Operating Costs Allocable to the Premises paid by Lessee to Lessor pursuant to
subsection (c), Lessee shall pay the amount of such excess to Lessor as added
Additional Rent within thirty (30) days after receipt of such statement by
Lessee. If such statement shows such costs to be less than the amount paid by
Lessee to Lessor pursuant to subsection (c), then the amount of such overpayment
by Lessee shall be credited by Lessor to the next immediate Rent payable by
Lessee.

             (e) Determinations. The determination of Actual Operating Costs and
                 --------------
Estimated Operating Costs Allocable to the Premises shall be made by Lessor.
Lessor or its agent shall keep records in reasonable detail showing all
expenditures made for the items enumerated above, which records shall be
available for inspection by Lessee at any reasonable time.

             (f) Beginning and End of Term.  If this Lease shall commence or
                 -------------------------                                  
terminate on a day other than the first or last day of a Lease Year, the amount
of any adjustment between Estimated and Actual Costs Allocable to the Premises
with respect to the Lease Year in which such commencement or termination occurs
shall be prorated on the basis which the number of days of such Lease Year bears
to 365; and any amount payable by Lessor to Lessee or Lessee to Lessor with
respect to such adjustment shall be payable within thirty (30) days after
delivery by Lessor to Lessee of the statement of Actual Costs Allocable to the
Premises with respect to such Lease Year.

             (g) Further Adjustment. In the event the average occupancy level of
                 ------------------ 
the Building for any Lease Year was or is not ninety percent (90%) of full
occupancy, then the Estimated Costs and Actual Costs for such year shall be
proportionately adjusted by Lessor to reflect those costs which would have
occurred had the Building been ninety percent (90%) occupied during such year.


             (h) Base Rent.  Notwithstanding anything to the contrary in this
                 ---------                                                   
Section 9, the Rent payable by Lessee shall in no event be less than the Rent
specified in Section 1(g) of this Lease.



             (i) Personal Property Taxes. Lessee shall pay, prior to
                 -----------------------
delinquency, all personal property taxes payable with respect to all Property of
Lessee located on the Premises or the Building and promptly, upon request of
Lessor, shall provide written proof of such payment. As 

                                       7
<PAGE>
 
used herein, "Property of Lessee" shall include all improvements which are paid
for by property taxes assessed against the Property of Lessee, whether assessed
as real or personal property.

          10.  COMPLIANCE WITH LAW.  Lessee shall not use the Premises or permit
               -------------------                                              
anything to be done in or about the Premises which will in any way conflict with
any law, statute, ordinance, or governmental rule or regulation now in force or
which may hereafter be enacted or promulgated.  Lessee shall at its sole cost
and expense promptly comply with all laws, statutes, ordinances, and
governmental rules, regulations, or requirements now in force or which may
hereafter be in force and with the requirements of any board of fire
underwriters or other similar body now or hereinafter constituted relating to or
affecting the condition, use, or occupancy of the Premises, excluding structural
changes not related to or affected by Lessee's improvements or acts.  The
judgment of any court of competent jurisdiction or the admission of Lessee in an
action against Lessee, whether Lessor be a party thereto or not, that Lessee has
violated any law, statute, ordinance, or governmental rule, regulation, or
requirement, shall be conclusive of that fact as between Lessor and Lessee.

          11.  ALTERATIONS BY LESSEE.
               --------------------- 

          11.1  Alterations.  Lessee shall in no event make or permit to be made
                -----------                                                     
any alteration, modification, substitution, or other change of any nature to the
mechanical, electrical, plumbing, HVAC, and sprinkler systems within or serving
the Premises.  After completion of Lessee's Improvements within the Premises,
Lessee shall not make or permit any other improvements, alterations, fixed
decorations, substitutions, or modifications, structural or otherwise, to the
Premises or the Building ("Alterations") without the prior written consent of
Lessor, any such consent to also include the conditions under which the
Alterations may be made (Lessor consent will not be unreasonably withheld).
Alterations shall include, but not be limited to, the installation or
modification of carpeting, walls, partitions, counters, doors, shelves, lighting
fixtures, hardware, locks, ceiling, and window and wall coverings; but shall not
include the initial Tenant Improvements placed within the Premises pursuant to
Exhibit A.  All such Alterations shall be made at Lessee's sole expense, by
contractors or subcontractors approved by Lessor, and only after (i) Lessee has
obtained any necessary permits from governmental authorities and  (ii) Lessee
has submitted complete plans and specifications to Lessor with respect to the
Alterations and Lessor has approved them.  Lessor, at its own expense, shall
have the right, but not the obligation, to supervise the making of any
Alterations by Lessee.  If any mechanic's lien is filed against the Premises or
the Building for work or materials furnished to Lessee, the lien shall be
discharged by Lessee within ten (10) days thereafter, solely at Lessee's
expense, by either paying off or bonding the lien.  Should Lessee fail to
discharge any lien within ten (10) days of its filing, Lessor shall have the
right, but not the obligation, to discharge said lien at Lessee's expense.
Lessee shall indemnify and hold Lessor harmless from any and all expenses
(including attorney fees), liens, claims, or damage to persons, property, or the
Building which may arise from the making of any Alterations.  Any Alterations
made without the prior consent of Lessor may be corrected or removed by Lessor,
and Lessee shall, on demand, pay the cost thereof as Additional Rent.  The work
relating to any Alterations shall not interfere with, or cause annoyance to, any
other tenants of the Building or disrupt any access to, or use of, the common
facilities.  Upon request, Lessee will deliver to Lessor a complete set of "as
built" plans showing the approved Alterations.

          11.2  Title.  Any Alterations or any equipment, machinery, furniture,
                -----                                                          
furnishings, and other property or improvements installed or located in the
Premises by or on behalf of Lessor or Lessee (i) shall, except for "Lessee's
Personal Property" as defined below, immediately become the property of Lessor
and (ii) shall remain upon and be surrendered to Lessor with the Premises as a
part thereof at the end of the Term; provided, however, that if Lessee is not in
Default under this Lease, Lessee shall have the right to remove, prior to the
end of the Term, Lessee's Personal Property.  Notwithstanding the foregoing,
Lessor may, upon notice to Lessee, elect that any Alterations be removed at the
end of the Term, and Lessee shall cause such Alterations to be removed at
Lessee's expense and shall restore the Premises to their condition prior to the
making of such Alterations, reasonable wear and tear excepted.  Upon Lessee's
failure to do so, Lessor may remove such Alterations and restore the Premises
and Lessee shall promptly reimburse Lessor for the cost of such work.

          11.3  Lessee's Personal Property.  "Lessee's Personal Property" shall
                --------------------------                                     
mean all equipment, machinery, furniture, furnishings, and/or other property now
or hereafter installed or placed in or on the Premises by and at the sole
expense of Lessee with respect to which Lessee has not been granted any credit
or allowance by Lessor and which (i) is not used, or was not procured for use,
in connection with the operation, maintenance or protection of the Premises or
the Building; (ii) is

                                       8
<PAGE>
 
removable without damage to the Premises or the Building, and (iii) is not a
replacement of any property of Lessor, whether such replacement is made at
Lessee's expense or otherwise. Notwithstanding any other provision of this
Lease, Lessee's Personal Property shall not include any Alterations or any
Improvements or other property installed or placed in or on the Premises as part
of Lessee's Improvements, whether or not any such Alterations, Improvements, or
other property were at Lessee's expense. Lessee shall promptly pay all personal
property taxes on Lessee's Personal Property, as applicable. Lessee shall remove
all Lessee's Personal Property from the Premises at the termination of this
Lease. Any property belonging to Lessee or any other person which is left in the
Premises after the date the Lease is terminated for any reason shall be deemed
to have been abandoned. In such event, Lessor shall have the right to declare
itself the owner of such property and to dispose of it in whatever manner Lessor
considers appropriate without waiving its right to claim from Lessee all
expenses and damages caused by Lessee's failure to remove such property, and
Lessee shall not have any right to compensation or claim against Lessor as a
result.

          12.  LOSS, DAMAGE, AND INJURY.  All the property of Lessee, its
               ------------------------                                  
agents, or invitees, or any other person, located in or on the Premises or the
Building, shall be and remain at the sole risk of Lessee or such agent, invitee,
or person.  Lessee hereby expressly agrees that Lessor and its agents, servants,
and employees shall not be liable or responsible for any damage or injury to the
person or property of Lessee, or its agents, servants, employees, licensees,
invitees, or contractors, directly or indirectly caused by, (i) dampness or
water in any part of the Premises or Buildings; (ii) bursting, leaking, or
overflow of water, sewer, steam, or sprinkler pipes and heating or plumbing
fixtures; (iii) air conditioning or heating failures; (iv) interruption or
variance in the quality of electrical service supplied to the Lessee; (v)
interference with light, air, or other incorporeal hereditaments; (vi)
operations in the construction of any public or quasi-public works; (vii) theft
or other crime, whether violent or non-violent in nature; (viii) fire, accident,
natural disaster, or other casualty; (ix) latent or apparent defect or change of
conditions in the Premises and/or the Building; and (x) any other source,
circumstance, or cause whatsoever, except to the extent such damage or injury is
caused by or directly attributable to the negligence or willful misconduct of
Lessor and/or its agents, servants, and employees, and then only to the extent
that Lessee, its agents, servants, employees, licensees, invitees, or
contractors are not compensated therefore by insurance (and, in any event,
subject to the provisions of Section 19 hereof).  No representation, guarantee,
assurance, or warranty is made or given by Lessor that the communications or
security systems, devices, or procedures used, if any, will be effective to
prevent injury to Lessee or any other person or damage to, or loss (by theft or
otherwise) of any of Lessee's property, or of the property of any other person,
and the Lessor reserves the right to discontinue or modify at any time such
communications or security systems, devices, or procedures without liability to
Lessee.

          13.  REPAIRS.  By entry hereunder, Lessee accepts the Premises as
               -------                                                     
being in good, sanitary order, condition, and repair.  Lessee shall, at Lessee's
sole cost and expense, keep the Premises and every part thereof in good
condition and repair, damage thereto by fire, earthquake, act of God, or the
elements excepted.  Lessee shall, upon the expiration or sooner termination of
the Term hereof, surrender the Premises to Lessor in the same condition as when
received, ordinary wear and tear and damage by fire, earthquake, act of God, or
the elements excepted.  It is specifically understood and agreed that Lessor has
no obligation and has made no promises to alter, remodel, improve, repair,
decorate, or paint the Premises or any part thereof and that no representations
respecting the condition of the Premises or the Building of which the Premises
are a part have been made by Lessor to Lessee except as specifically herein set
forth.  Lessor shall keep the Building and all machinery, equipment, fixtures,
and systems of every kind attached to, or used in connection with the operation
of the Building, including all electrical, heating, mechanical, sanitary,
sprinkler, utility, power, plumbing, cleaning, refrigeration, ventilating, air
conditioning, and elevator systems and equipment (excluding, however, lines,
improvements, systems, and machinery for water, gas, steam, and electricity
owned and maintained by any public utility company or governmental agency or
body or any supplemental equipment as provided in Section 8(c), Additional
Services) in good order and repair consistent with operation of the Building as
a first-class office building.  Lessor, at its cost and expense, shall make all
repairs and replacements necessary to comply with its obligations set forth in
the immediately preceding sentence except for repairs caused by the negligence
or willful misconduct of Lessee, its agents, employees, invitees, and guests,
which repairs shall be made by Lessor at the cost of Lessee, and for which
Lessee shall pay promptly upon receipt of an invoice setting forth the cost of
such repairs.  There shall be no abatement of rents due and payable hereunder
and no liability on the part of Lessor by reason of any inconvenience,
annoyance, or injury arising from Lessor's making reasonable repairs, additions,
or improvements to the Building in accordance with its obligations hereunder.

                                       9
<PAGE>
 
          14.  ABANDONMENT.  Lessee shall not vacate or abandon the Premises at
               -----------                                                     
any time during the Term, and if Lessee shall abandon, vacate, or surrender said
Premises, or be dispossessed by process of law, or otherwise, any personal
property belonging to Lessee and left on the Premises shall be deemed to be
abandoned.  Any expense incurred by Lessor in moving, storing, or disposing of
such property shall be paid by Lessee upon demand of Lessor.

          15.  LIENS.  Lessee shall keep the Premises and the property in which
               -----                                                           
the Premises are situated, free from any liens arising out of any work
performed, materials furnished, or obligations incurred by Lessee.

          16.  ASSIGNMENT AND SUBLETTING.  Lessee shall not assign, transfer,
               -------------------------                                     
mortgage, pledge, hypothecate, or encumber this Lease, or any interest therein,
and shall not sublet the said Premises or any part thereof, or any right or
privilege appurtenant thereto, or suffer any other person (the agents and
servants of Lessee excepted) to occupy or use the said Premises, or any portion
thereof, without the written consent of Lessor (Lessor consent will not be
unreasonably withheld).  A consent to one assignment, subletting, occupation, or
use by any other person shall not be deemed to be a consent to any subsequent
assignment, subletting, occupation, or use by another person.  Any such
assignment or subletting without such consent shall be void, and shall, at the
option of Lessor, terminate this Lease.   This Lease shall not, nor shall any
interest therein, be assignable as to the interest of Lessee by operation of
law, without the written consent of Lessor.  Any assignment of this Lease by
Lessee shall not relieve Lessee of its obligations hereunder, including its
obligation for payment of Rent.

          Without limiting the generality of the foregoing, Lessor may condition
its consent to any transfer upon satisfaction of all or any of the following
conditions:

          (a) the net assets of the assignee, licensee, sublessee, or other
transferee or permittee (collectively "transferee") immediately prior to the
transfer shall not be less than the greater of the net assets of Lessee
immediately prior to the transfer or the net assets of Lessee at the time of the
signing of this Lease;

          (b) such transfer shall not adversely affect the quality and type of
business operation which Lessee has conducted theretofore;

          (c) such transferee shall assume in writing, on a form acceptable to
Lessor, all of Lessee's obligations hereunder and Lessee shall provide Lessor
with a copy of such assumption/transfer document;

          (d) Lessee shall pay to Lessor a transfer fee of Five Hundred Dollars
($500.00) prior to the effective date of the transfer plus all out-of-pocket
expenses to reimburse Lessor for costs and expenses incurred with respect to the
transfer, including, without limitation, review of financial materials, meetings
with representatives of transferor and/or transferee, and preparation, review,
approval, and execution of the required transfer documentation;

          (e) Lessee to which the Premises were initially leased shall continue
to remain liable under this Lease for the performance of all terms, including,
but not limited to, payment of Rental due under this Lease;

          (f) each of Lessor's Mortgagees shall have consented in writing to
such transfer; and

          (g) such other conditions as Lessor may reasonably deem
appropriate.

          Without limiting Lessor's right to withhold its consent to any
transfer by Lessee, and regardless of whether Lessor shall have consented to any
such transfer, neither Lessee nor any other person having an interest in the
possession, use, occupancy, or utilization of the Premises or any part thereof
shall enter into any lease, sublease, license, concession, assignment, or other
transfer or agreement for use, occupancy, or utilization of all or any portion
of the Premises which provides for rental or other payment for such use,
occupancy, or utilization calculated, in whole or in part, on the basis of the
net income or profits derived by any person or entity from the space so leased,
used, occupied, or utilized, and any such purported lease, sublease, license,
concession, assignment, or other transfer or agreement shall be absolutely void
and ineffective as a conveyance

                                       10
<PAGE>
 
of any right or interest in the possession, use, occupancy, or utilization of
all or any part of the Premises. There shall be no deduction from the rental
payable under any sublease or other transfer nor from the amount thereof passed
on to any person or entity, for any expenses or costs related in any way to the
subleasing or transfer of such space.

          Regardless of whether Lessor shall have consented to a transfer
(including, without limitation, a sublease, concession agreement, or other
arrangement whereby all or any portion 1 of the Premises are used or occupied by
a party other than Lessee), any and all amounts received as a result of such
transfer, as sub-rent or otherwise, shall be the property of and payable to
Lessor to the extent that such amount (calculated on a square foot basis) is
greater than 1.15 times the Annual Basic Rental (on a per square foot basis)
payable under this Lease, but the same shall not be deemed to be a consent by
Lessor to any such transfer or a waiver of any right or remedy of Lessor
hereunder.  Nothing in this section shall prevent Lessee, on approved
assignments and sublets, from receiving sublease Rental payments which are less
than 1.15 times the Annual Basic Rental (on a square foot basis) payable under
this Lease so long as Lessee is not in default under this Lease, including
payment of the full Rental amount.

          17.  ACCIDENT - INDEMNITY.  Lessee shall defend and indemnify Lessor
               --------------------                                           
and save it harmless from and against any and all liability, damages, costs, or
expenses, including attorney fees, arising from any act, omission, or negligence
of Lessee, or the officers, contractors, licensees, agents, servants, employees,
guests, or invitees of Lessee in or about the Premises or the Building or
appurtenances thereto or arising from any accident, injury, or damage, howsoever
and by whomsoever caused, to any person or property, occurring in or about the
Premises or the Building or appurtenances thereto provided that the foregoing
provisions shall not be construed to make Lessee responsible for loss, damage
liability, or expense resulting from injuries to third parties caused by the
negligence of Lessor, or of any officer, contractor, licensee, agent, servant,
employee, guest, or invitee of Lessor.

          18.  INSURANCE.
               --------- 

          18.1.  Lessee's Insurance.  Lessee, at its expense, shall obtain and
maintain in effect as long as this Lease remains in effect and during such other
time as Lessee occupies the Premises or any part thereof insurance policies
providing at least the following coverage:

          a.      Comprehensive general liability insurance, including insurance
against assumed or contractual liability under this Lease, with respect to the
Premises, to afford protection with limits, per occurrence, of not less than One
Million Dollars ($1,000,000), combined single limit, with respect to personal
injury and death and property damage, such insurance to provide for no
deductible;

          b.      All-risk property and casualty insurance, including theft,
written at replacement cost value and with replacement cost endorsement,
covering all of Lessee's Personal Property in the Premises; and

          c.      If, and to the extent, required by law, worker's compensation
or similar insurance offering statutory coverage and containing statutory
limits.  Employer's liability coverage of not less than One Hundred Thousand
Dollars ($100,000).

          Such policies will be maintained in companies and in form reasonably
acceptable to Lessor and will be written as primary policy coverage and not
contributing with, or in excess of, any coverage which Lessor shall carry.
Lessee will deposit the policy or policies of such required insurance or
certificates thereof with Lessor prior to the Lease Commencement Date, which
policies shall name Lessor or its designee as additional named insured with
regard to Section 18.1a. and loss payee with regard to Section 18.1b. and shall
also contain a provision stating that such policy or policies shall not be
cancelled or materially altered except after thirty (30) days written notice to
Lessor.  All such policies of insurance shall be effective as of the date Lessee
occupies the Premises and shall be maintained in force at all times during the
Term of this Lease and all other times during which Lessee shall occupy the
Premises.  In addition to the foregoing insurance coverage, Lessee shall require
any contractor retained by it to perform work on the Premises to carry and
maintain, at no expense to Lessor, during such times as contractor is working in
the Premises, a non-deductive (i) comprehensive general liability insurance
policy, including, but not limited to, contractor's liability coverage,
contractual liability coverage, completed operations coverage, broad form
property damage endorsement, and contractor's protective liability coverage,

                                       11
<PAGE>
 
to afford protection with limits per occurrence, of not less than One Million
Dollars ($1,000,000), combined single limit, with respect to personal injury and
death and property damage, such insurance to provide for no deductible, and (ii)
worker's compensation insurance or similar insurance in form and amounts as
required by law. In the event of damage to or destruction of the Premises and
the termination of this Lease by Lessor, Lessee agrees that it will pay Lessor
all of its insurance proceeds relating to Tenant Improvements and Alterations
made in the Premises by or on behalf of Lessee.

          Lessor shall not be required to carry insurance of any kind on
Lessee's Improvements (other than those Improvements specified in Exhibit A by
Lessor), installed within the Premises by or on behalf of Lessee or any other
property of Lessee, and Lessor shall not be obligated to repair any damage
thereto or replace the same.  Lessor is not responsible for any loss or damage
falling under Lessee's deductible.

          18.2  Lessee's Failure to Insure.  If Lessee shall fail to obtain
                --------------------------                                 
insurance as required under this Section 18, Lessor may, but shall not be
obligated to, obtain such insurance, and in such event, Lessee agrees to pay, as
Additional Rent, the premium for such insurance upon demand by Lessor.

          18.3  Compliance with Policies.  Lessee will not do or suffer to be
                ------------------------                                     
done, or keep or suffer to be kept, anything in, upon or about the Premises
which will contravene Lessor's policies insuring against loss or damage by fire,
other casualty, or any other cause, including without limitation, public
liability, or which will prevent Lessor from procuring such policies in
companies acceptable to Lessor.  If any act or failure to act by Lessee in and
about the Building and the Premises shall cause the rates with respect to
insurance policies required to be maintained by Lessor under this Section 18 or
under the provisions of leases with respect to any other tenants in the
Building, to be increased beyond those rates that would normally be applicable
for such coverages, Lessee will pay, as Additional Rent, the amount of any such
increases upon demand by Lessor.

          19.  WAIVER OF SUBROGATION.  Lessor and Lessee do each herewith and
               ---------------------                                         
hereby release and relieve the other from responsibility for, and waive their
entire claim of recovery for (i) any loss or damage to the real or personal
property either located anywhere in the Premises or the Building and including
the Building itself, arising out of or incident to the occurrence of any of the
perils which may be covered by the fire and lightning insurance policy, with
all-risk endorsement, in common use in the Seattle locality, or (ii) loss
resulting from business interruption at the Premises or loss of Rental income
from the Building, arising out of or incident to the occurrence of any of the
perils which may be covered by the business interruption insurance policy and by
the loss of rental income insurance policy in common use in the Seattle locality
whether the loss or damage is due to the negligence of either said parties,
their agents or employees, or any other cause. Each party shall obtain any
special endorsements, if required by their insurer, to evidence compliance with
the aforementioned waiver to the extent such waivers are reasonably available.

          20.  PERSONAL PROPERTY TAX.  Lessee agrees to pay or cause to be paid,
               ---------------------                                            
before delinquency, any and all taxes levied or assessed upon all equipment,
furniture, fixtures, and other personal property located in the Premises except
that which may be owned by Lessor.

          21.  RULES AND REGULATIONS.  Lessee shall faithfully observe and
               ---------------------                                      
comply with the rules and regulations printed on or annexed to this Lease and
all reasonable modifications of and additions thereto from time to time put into
effect by Lessor notice of which shall be given to Lessee.  Lessor shall not be
responsible to Lessee for the nonperformance by any other tenant or occupant of
the Building of any of said rules and regulations.

          22.  HOLDING OVER.  Lessee agrees to vacate the Premises at the end of
               ------------                                                     
the Term.  If Lessee holds possession of the Premises after the Term of this
Lease, Lessee shall become a tenant from month to month upon the terms herein
specified but at a monthly rental equivalent to 125% of the then prevailing
Rental paid by Lessee at the expiration of the Term of this Lease pursuant to
all of the provisions of Sections 3 and 9  hereof, payable in advance on or
before the first day of each month, and Lessee shall continue in possession
until such tenancy shall be terminated by Lessor, or until Lessee shall have
given to Lessor a written notice of his intention to terminate at least one
month prior to the date of termination of such monthly tenancy.

          23.  ENTRY BY LESSOR.  Lessor reserves and shall at any and all
               ---------------                                           
reasonable times have the right to enter the Premises to inspect same, to supply
janitor service, and any other service to be provided by Lessor to Lessee
hereunder, to submit said Premises to prospective purchasers or

                                       12
<PAGE>
 
tenants, to post notices of nonresponsibility, and to alter, improve, or repair
the Premises and any portion of the Building of which the Premises are a part,
without abatement of Rent, and may for that purpose erect scaffolding and other
necessary structures where reasonably required by the character of the work to
be performed, always providing the entrance to the Premises shall not be blocked
thereby, and further providing that the business of Lessee shall not be
interfered with unreasonably. Lessee hereby waives any claim for damages for any
injury or inconvenience to or interference with Lessee's business, any loss of
occupancy or quiet enjoyment of the Premises, and any other loss occasioned
thereby. For each of the aforesaid purposes, Lessor shall at all times have and
retain a key with which to unlock all of the doors in, upon, and about the
Premises, excluding Lessee's vaults and safes, and Lessor shall have the right
to use any and all means which Lessor may deem proper to open said doors in an
emergency, in order to obtain entry to the Premises, and any entry to the
Premises obtained by Lessor by any of said means, or otherwise, shall not under
any circumstances be construed or deemed to be a forcible or unlawful entry
into, or a detainer of, the Premises, or an eviction of Lessee from the Premises
or any portion thereof.

          24.  INSOLVENCY OR BANKRUPTCY.  Either (a) the appointment of a
               ------------------------                                  
receiver to take possession of all or substantially all of the assets of Lessee;
or (b) an assignment by Lessee for the benefit of creditors; or (c) any action
taken or suffered by Lessee under any insolvency, bankruptcy, or reorganization
act, shall constitute a breach of this Lease by Lessee.  Upon the happening of
any such event, this Lease shall terminate five (5) days after written notice of
termination from Lessor to Lessee.  In no event shall this Lease be assigned or
assignable by operation of law or by voluntary or involuntary bankruptcy
proceedings or otherwise and in no event shall this Lease or any rights or
privileges hereunder be an asset of Lessee under any bankruptcy, insolvent, or
reorganization proceedings.

          If, despite the foregoing provisions of this Section 24, Lessee shall
voluntarily or involuntarily come under the jurisdiction of the Federal
Bankruptcy Code and thereafter Lessee or its trustee in bankruptcy, under the
authority of and pursuant to applicable provisions thereof, shall determine to
assign this Lease (and be so entitled to assign this Lease), Lessee agrees that
(i) Lessee or its trustee will provide to Lessor sufficient information enabling
it to independently determine whether Lessor will incur actual and substantial
detriment by reason of such assignment and (ii) "adequate assurance of future
performance" under this Lease, as that term is generally defined under the
Federal Bankruptcy Code, will be provided to Lessor by Lessee and its assignee
as a condition of said assignment.

          25.  DEFAULT.  The occurrence of any one or more of the following
               -------                                                     
events shall constitute a default and breach of this Lease by Lessee:  (a)  The
vacating or abandonment of the Premises by Lessee; (b)  The failure by Lessee to
make any payment of Rent or any other payment required to be made by Lessee
hereunder, as and when due, where such failure shall continue for a period of
three (3) days after written notice thereof by Lessor to Lessee; (c)  The
failure by Lessee to observe or perform any of the covenants, conditions, or
provisions of this Lease to be observed or performed by the Lessee, other than
described in (b) above, where such failure shall continue for a period of thirty
(30) days after written notice thereof by Lessor to Lessee;  provided, however,
that if the nature of Lessee's default is such that more than thirty (30) days
are reasonably required for its cure, then Lessee shall not be deemed to be in
default if Lessee commences such cure within said thirty (30) day period and
thereafter diligently prosecutes such cure to completion.

          26.  REMEDIES IN DEFAULT.  In the event of any Default or breach by
               -------------------                                           
Lessee, Lessor may at any time thereafter, with or without notice or demand and
without limiting Lessor in the exercise of a right or remedy which Lessor may
have by reason of such default or breach:

          (a) Terminate Lessee's right to possession of the Premises by any
lawful means, in which case Lessee shall immediately surrender possession of the
Premises to Lessor and Lessor may reenter and occupy the Premises.  Reentry and
taking of possession pursuant to this paragraph shall not be construed as an
election to terminate the Lease unless a written notice of intention to so
terminate is provided to Lessee by Lessor.  Upon such reentry, Lessor shall have
the right to relet all or any part of the Premises for any such term or terms
and conditions as Lessor in its sole discretion may deem advisable with the
right to complete construction of or make Alterations and repairs to the
Premises.  Lessee shall pay to Lessor in the event of such reletting, as soon as
ascertained, the costs and expenses incurred by Lessor in such reletting,
completion of construction, or in making such Alterations and repairs.  Rentals
received by Lessor from such reletting shall be applied:  first to the payment
of any indebtedness, other than Rent, due hereunder from Lessee to Lessor,
including costs of renovation and Alteration of the Premises, reasonable
attorney fees, and

                                       13
<PAGE>
 
real state commissions paid; second, to the payment of Rent due and payable
hereunder and to any other payments required to be made by Lessee hereunder; and
the residue, if any, shall be held by Lessor in payment of future Rent or
damages as the same may become due and payable hereunder; and the balance, if
any, at the end of the Term of this Lease shall be paid to Lessee. Should such
Rentals received from time to time from such reletting during any month be a
lesser Rental than herein agreed to by Lessee, Lessee shall pay such deficiency
to Lessor. Lessee shall pay such deficiency each month as the amount thereof is
ascertained by Lessor.

          (b) Lessor shall have the right, at Lessor's option, to suspend or
discontinue the services specified in Section 8 hereof, during the continuance
of any Default or breach and such suspension or discontinuance shall not be
deemed or construed to be an eviction or ejection of Lessee.

          (c) Lessor shall also have the right upon Lessee's Default to
terminate this Lease by giving Lessee written notice thereof; to accelerate all
Rent payments due hereunder for the remaining Term hereof, or if any extension
option has been exercised, for the remainder of such option term; and to recover
from Lessee all damages incurred by Lessor by reason of Lessee's Default
including, but not limited to, the cost of recovering possession of the
Premises, expenses of reletting, including renovation and Alteration of the
Premises, reasonable attorney fees, any real estate commissions paid, all past
due Rent, and the worth at the time of the award by the court having
jurisdiction thereof of the amount by which the unpaid Rent for the balance of
the term, or if an extension option has been exercised, for the remainder of
such option term, exceeds the amount of such Rental for the same period that
Lessee proves could be reasonably avoided.  Unpaid installments of Rent or other
sums shall bear interest from the date due at the rate of eighteen percent
(18%).  In the event Lessee shall have abandoned the Premises, Lessor shall have
the option of (a) taking possession of the Premises and recovering from Lessee
the amounts specified in subparagraph (a) or (c) of this paragraph, or (b)
proceeding under the provisions of the following subparagraph (d).

          (d) Maintain Lessee's right to possession, in which case this Lease
shall continue in effect whether or not Lessee shall have abandoned the
Premises.  In such event, Lessor shall be entitled to enforce all of Lessor's
rights and remedies under this Lease, including the right to recover Rent as it
becomes due hereunder.

          (e) Pursue any other remedy now or hereafter available to Lessor under
the laws or judicial decisions of the State of Washington in which state the
Premises are located.

          27.  LATE CHARGES.  Lessee hereby acknowledges that late payment by
               ------------                                                  
Lessee to Lessor of Rent or other sums due hereunder will cause Lessor to incur
costs not contemplated by this Lease, the exact amount of which will be
extremely difficult to ascertain.  Such costs include, but are not limited to,
processing and accounting charges, and late charges which may be imposed upon
Lessor by terms of any mortgage or trust deed covering the Premises.
Accordingly, if any installment of Rent or any sum due from Lessee shall not be
received by Lessor or Lessor's designee within three (3) days after the due
date, then Lessee shall pay to Lessor a late charge equal to the maximum amount
permitted by law (and in the absence of any governing law, five percent (5%) of
such overdue amount), plus any attorney fees incurred by Lessor by reason of
Lessee's failure to pay Rent and/or other charges when due hereunder.  The
parties hereby agree that such late charges represent a fair and reasonable
estimate of the cost that Lessor will incur by reason of the late payment by
Lessee.  Acceptance of such late charges by the Lessor shall in no event
constitute a waiver of Lessee's default with respect to such overdue amount, nor
prevent Lessor from exercising any of the other rights and remedies granted
hereunder.

          28.  RECONSTRUCTION.  In the event the Premises or the Building of
               --------------                                               
which the Premises are a part are destroyed or damaged by any casualty, Lessor
shall have the option to repair or replace the damaged or destroyed part or to
terminate this Lease by giving written notice of its election to terminate
within 30 days of such event.  If Lessor does not terminate this Lease, Lessor
shall have a period of at least 180 days to complete the repair or replacement
of the damaged or destroyed part from the later of the date of the casualty or
the date of the completion of the insurance adjustment made in connection with
such casualty, and provided insurance proceeds are made available and are
permitted to be used for such purpose by the holder of the most senior mortgage
or deed of trust applicable to the real property in which the Premises are
located.  If Lessor does not terminate, this Lease shall remain in full force
and effect, except that Lessee shall be entitled to a proportionate reduction of
Rent while such repairs are being made, such proportionate reduction to be based
upon the extent to which the Premises are rendered

                                       14
<PAGE>
 
untenantable and making of such repairs shall interfere with the business
carried on by Lessee in the Premises.

          Lessor shall not be required to repair any injury or damage by fire or
other cause, or to make any repairs or replacements of any panels, decoration,
office fixtures, ceiling, floor covering, partitions, or any other property
placed in the Premises by Lessee.  Lessor shall not be liable for any loss due
to interruption of Lessee's business.  Any proceeds which may become payable to
Lessor under any policies for fire or other casualty insurance applicable to the
Building in which the Premises are located may be applied by Lessor either to
repair any damage with respect to which such insurance proceeds become payable
or to reduce any outstanding indebtedness of Lessor which is secured by a
mortgage or deed of trust applicable to the real property in which the Premises
are located.

          29.  EMINENT DOMAIN.  If all or any part of the Premises shall be
               --------------                                              
taken or appropriated by any public or quasi-public authority under the power of
eminent domain, Lessor shall have the right, at its option, to terminate this
Lease, and Lessor shall be entitled to any and all income, rent, award, or any
interest therein whatsoever which may be paid or made in connection with such
public use or purpose, and Lessee shall have no claim against Lessor for the
value of any unexpired term of this Lease.  If a part of the Premises shall be
so taken or appropriated and Lessor shall not elect to terminate this Lease, the
rental thereafter to be paid shall be reduced proportionately based on the area
taken, and Lessor shall make, or cause to be made, such repairs and alterations
as may reasonably be necessary to restore any part of the Premises not taken to
useful condition, provided a sufficient portion of the condemnation award is
made available and permitted to be used for such purpose by the holder of the
most senior mortgage or deed of trust applicable to the real property in which
the Premises are located.  If any part of the Building other than the Premises
shall be so taken or appropriated, Lessor shall have the right, at its option,
to terminate this Lease and shall be entitled to the entire award, as above
provided.

          30.  SUBORDINATION.  This Lease is subject and subordinate to the
               -------------                                               
lien, operation, and effect of any sale/leaseback or lease/subleaseback
transaction, mortgage, or deed of trust to any bank, insurance company, or other
lending institution, now in force, and to any first mortgage or first deed of
trust hereafter in force, against the land and/or Building of which the Premises
are a part, and upon any buildings hereafter placed upon the land of which the
Premises are a part, and to all advances made or hereafter to be made upon the
security thereof.  This Lease shall also be subject and subordinate to any
ground lease now or hereinafter in force and applicable to the real property on
or in which the Premises are located.  If requested by Lessor, Lessee shall
promptly execute any certificate or other document confirming such
subordination.

          If any person or party shall succeed to all or part of Lessor's
interest in the Premises, whether by purchase, foreclosure, deed in lieu of
foreclosure, power of sale, cancellation, or termination of Lease (including,
without limitation, ground lease) or otherwise, whether voluntary, involuntary,
or by operation of law, and if so requested or required by such successor in
interest, Lessee shall attorn fully and completely to such successor in interest
and shall recognize such successor in interest as Lessor under this Lease for
the balance of the term of this Lease upon the same terms and conditions
provided herein, and Lessee shall execute such agreement in confirmation of such
attornment as such successor in interest shall reasonably request.

          Notwithstanding anything contained herein to the contrary, he holder
of any mortgage or deed of trust may at any time subordinate the lien of its
mortgage or deed of trust to the operation and effect of this Lease without
obtaining the Lessee's consent thereto, by giving the Lessee written notice
thereof, in which event this Lease shall be deemed to be senior to such mortgage
or deed of trust without regard to the respective dates of execution and/or
recordation of such mortgage or deed of trust and this Lease and thereafter such
holder of such mortgage or deed of trust shall have the same rights as to this
Lease as it would have had were this Lease executed and delivered before the
execution of such mortgage or deed of trust.

          The provisions of this Article to the contrary notwithstanding, and so
long as Lessee is not in default hereunder, this Lease shall remain in full
force and effect for the full Term hereof.

          31.  SALE BY LESSOR.  In the event of a sale or conveyance by Lessor
               --------------                                                 
of the Building containing the Premises, the same shall operate to release

*Nothwithstanding the schedule above, Lessee shall be responsible for rent on
any space occupied within the Premises which is occupied ahead of schedule. In
other words, Lessee shall be responsible for monthly rent payments on space
occupied within the Premises on the earlier of (i) the date shown in the
schedule above or (ii) the date space is occupied. Occupied space shall be the
net rentable area, including circulation space internal to the premises, that is
being utilized by Lessee's employees, agents, contractors, subtenants and the
like including the use of furniture, fixtures, files, storage, and other
beneficial uses of the Premises.

3.        Lease Renewal Options
          ---------------------

So long as Lessee is not in default under the terms of this lease and provided
that Lessee is occupying one full floor, Lessee shall have the option to extend
the lease for one (1) renewal period of five (5) years. Lessee shall exercise
its options by providing six (6) months written notice to Lessor prior to the
end of the preceding Lease Term. The rent during the renewal term shall be equal
to ninety-five percent (95%) of the market rent for similar space in comparable
buildings within the Seattle Central Business District ("CBD").

4.        Expansion Option/Right of First Offer
          -------------------------------------

For so long as Lessee is not in default of the Lease and subject to the pre-
existing rights of Lessor's existing tenants, Lessee shall have:

(a)  The option to lease all vacant space located upon the eighteenth (18th) and
     twentieth (20th) floors, as said space becomes available, upon terms and
     conditions identical to those applicable to Lessee's existing space
     (including provisions relating to tenant improvements and design
     reimbursement). With respect to expansion space taken under this provision
     (a), the following shall apply:

                                       1
<PAGE>
 
         (i)    Lessor shall notify Lessee as vacant space becomes available and
                Lessee shall have ten (10) days within which to exercise its
                option to Lease the space on the date it becomes available,
         
         (ii)   Lessor shall not be responsible to lease space to Lessee for any
                term less than two (2) years,

         (iii)  Lessor shall not be responsible for any tenant improvements for
                any term less than three (3) years, provided however, that
                should Lessee exercise its option to renew per Special Provision
                #3 above, the improvements that would have been provided by
                Lessor if the term of the expansion space was greater than three
                (3) years will be reimbursed by Lessor upon said renewal,
                
         (iv)   Any space taken after the 26th month of the initial term shall
                be at market rental rates as defined in above;
                
(b)  If option (a) above is not exercised, Lessee shall have the right of first
     offer to lease the space on the eighteenth (18th) or twentieth (20th)
     floors of the building. Lessor will provide Lessee with a schedule of
     existing lease terms (including option rights) for tenants currently
     occupying space on the floors subject to Lessee's option and right of first
     offer. In the event that Lessor desires to make a written offer (the
     "Offer") to a third party to lease the option space, Lessor shall first
     present the Offer to Lessee and give Lessee ten (10) business days within
     which to determine whether Lessee will accept the Offer. If Lessee gives
     Lessor written notice within such ten (10) day period that Lessee intends
     to accept the Offer, then Lessee shall be bound to enter into a written
     Lease Agreement in accordance with the terms of the Offer. If Lessee does
     not give Lessor such written notice within the ten (10) day period, then
     Lessor shall be free to close the transaction with another party on
     substantially the same terms as the Offer and Lessee's right of first
     offer, with respect to the expansion space delineated in such Offer, shall
     terminate and be of no further force or effect.

5.        Early Termination
          -----------------

Lessee shall have the option of terminating this Lease effective at any time
after the 36th month of the Lease Term. Lessee will provide Lessor at least 180
days written notice of its election to terminate. The written notice will
specify the reason for Lessee's termination. Upon vacating the Premises, lessee
shall pay Lessor a cash termination penalty equal to the uanmortized costs of
tenant improvements, leasing commissions, moving allowances, and architectural
fees (based on a 60-month straight-line amortization) plus:

          An amount equal to three (3) months' rent if the termination occurs
          between the 36th and the 42nd month of the Lease term;

          An amount equal to two (2) months' rent if the termination occurs
          between the 42nd and 48th month of the Lease term; and

          An amount equal to one (1) months' rent if the termination occurs
          after the commencement of the 48th month of the Lease term.

The intent of this early termination agreement is to allow Lessee flexibility if
it should have to downsize its operation as a result of a material loss in its
sales or should it need additional space as a result of increased sales.
Therefore, this early termination option may only be exercised for one or all of
the following reasons:

                                       2
<PAGE>
 
1.   Reduction in the size of the existing space is not approved.

     Prior to any termination, Lessor shall be given the option to reduce
     Lessee's space and keep Lessee as a tenant within a smaller premises.
     Within thirty (30) days after providing the termination notice described
     above, Lessor shall have the option to decide to reduce Lessee to the size
     so stated by Lessee. If Lessor elects to reduce the size of Lessee's space,
     then the termination payments due by Lessee to Lessor as outlined above
     shall be prorated on the amount of space reduced (i.e. if ten percent (10%)
     of the spaces is given up, the amount of the payment will be 10% of the
     total amount of the payment that would have been paid if the entire lease
     had been terminated). If Lessor does not exercise its option for the
     contraction of space, then Lessee may terminate as described above in this
     Section. Lessor will provide written notice of its election with the thirty
     (30) day time period.

2.   Cessation of business by Lessee.

3.   Expansion space is not available.

     If Lessee's termination notice specifies that Lessee requires at least a
     twenty-five percent (25%) increase in its space and Lessor cannot
     accommodate this growth in reasonable units of space in the building within
     six (6) months of said notice. Any space provided to Lessee by Lessor must
     be within the same elevator bank as the existing premises. Lessor will
     notify Lessee in writing within sixty (60) days after the receipt of
     Lessee's termination notice of Lessor's ability to fulfill Lessee's
     additional space requirements.

Both Lessor and Lessee agree that the early termination option is not to be used
to facilitate the move of Lessee from Westlake Center to another building in the
Seattle-Bellevue Metropolitan area prior to the end of the initial Lease Term as
stated above.

6.        Parking
          -------

Lessee shall have the option to enter into parking contracts for up to twelve
(12) automobiles in the building's underground parking facility based upon its
initial occupancy of 14,000 square feet. Additional parking may be taken with
the stepped absorption of space on the ration of one (1) space for each 1,200
square feet taken. Should Lessee not elect to enter into their allotted parking
contracts within thirty (30) days of occupancy or should Lessee cancel parking
contracts during the term of the Lease, then the contracts shall revert back to
Lessor for Lessor's use, and thereafter Lessee may have the right to pick the
spaces back up with sixty (60) days written notice.

7.        Relocation Costs
          ----------------

Lessor shall reimburse Lessee for the actual costs of relocation of furniture,
equipment, and files up to $1.00 per square foot of total committed space
(24,725 SF). Lessee will coordinate bids from responsible firms to select a bid
for relocation with review and approval by Lessor.

8.        Working/Construction Drawings
          -----------------------------

Lessor shall pay Marvin Stein & Associates for the actual costs of all working
drawings required for completion of quality tenant space.

                          Lessee's Plan Requirements

The Commencement Date for the Lease and the special provision for early
occupancy (Special Provision # 1) are based upon Lessee providing Lessor fully
approved working drawings and material selections on a timely basis in order to
allow issuance of said working drawings for commencement of construction of the
Premises on the 19th floor no later than August 7, 1995.  Working drawings for
the 18th floor shall be issued, approved for construction, on the earlier of (a)
April 15, 1996 or (b) seventy-five (75) days prior to the date Lessee seeks
occupancy on the 18th floor.

Included within the Lessee provided material selections and information are the
following:

 .  Selection of carpet and paint colors.
 .  Location of all data outlets.
 .  Location of new electrical and telephone outlets.
 .  Partition plan.
 .  Reflected ceiling plan.
 .  Other information necessary to obtain a building permit.

If, through no fault of Lessor, Lessee provides the working drawings and
material selections after the dates stated above and this delays the occupancy
of the Premises then, notwithstanding the provisions of Section 5 of the lease,
the Commencement Date of the lease shall not be extended and the payment of rent
shall commence on the Commencement Date.

  Whereas the parties hereto have heretofore entered into a Lease executed under

and 16,660 square feet on the Nineteenth Floor, for a combined total of 24,725

          Lots 1, 2, 3, 7, 8, 9, 10, 11 and 12, Block 1, ADDITION TO THE 
          TOWN OF SEATTLE as laid off by the Heirs of SARAH A. BELL, 
          deceased (commonly known as Heirs of SARAH A. BELL'S ADDITION 
          TO THE CITY OF SEATTLE) according to the plat recorded in Volume 
          1 of Plats, page 103, in King County, Washington;

          EXCEPT the Southwesterly 12 feet of said Lots 1, 2 and 3 condemned 
          by the City of Seattle in King County Superior Court Cause No. 
          52280, for the widening of Fourth Avenue, as provided by Ordinance 
          13776 of said City; and

          EXCEPT the Southeasterly 7 feet of said Lots 1 and 12 condemned by 
          the City of Seattle, in King County Superior Court Cause No. 57057 
          for the widening of Pine Street as provided by Ordinance 14500 of 
          said City;

          TOGETHER WITH all of the vacated alley lying within said Block 1.

          Pine Street on the south, Fourth Avenue on the west, and Olive 
          Way on the north.

  Whereas the parties desire to expand the Premises by 3,621 square feet of Net
Rentable Area on the 18th Floor of said Lease.   Now, therefore, for good and
valuable consideration, the receipt and adequacy of which is hereby
acknowledged, the parties agree to amend the Lease, effective February 1, 1999,
as follows:

      1.  Section 1(b), Premises, is amended to show that the square footage of
          the Premises has been revised from 24,725 S.F. to 28,346 S.F.
          Therefore, Section 1(b), Premises, is amended to read as follows:

          "Premises:  Consisting of 16,660 square feet of net rentable area on
          the 19th floor and 11,686 square feet of net rentable area on the 18th
          Floor for a combined total of 28,346 square feet of net rentable area
          of the building, as outlined on the floor plan attached hereto as
          Exhibit C-1, including tenant improvements, if any, as described in
          Exhibit A-1."

      2.  Section 1(c), Floor Areas, is amended to show that the agreed rentable
          area of the Premises has been revised from 24,725 square feet to
          28,346 square feet. Therefore, Section 1(c) is amended to read as
          follows:

          "The agreed net rentable area of the Premises is 28,346 square feet
          and of the building is 335,850 square feet."

      3.  Section 1(e), Commencement Date, is amended to show the term for the
          Lease expansion commences February 15, 1999.

      4.  Section 1(f), Expiration Date, for the 24,725 square feet is not
          amended.  The expiration date for the 3,621 square feet of expansion
          space shall be co-terminus with the 24,725 square feet.  Therefore,
          the expiration date for the 28,346 square feet shall be October 31,
          2000.

5.        Section 1(j), Exhibits, is amended to include the attached Exhibit A-

          Attachment II, Special Provision #2, of the Lease Agreement, shall be

Assumptions:
The above price schedule and description of work is based on the below
assumptions. 
1. Primus will provide the necessary technical environment for onsite work.
2. Primus will supervise and lead all onsite testing work conducted by EGS.
3. Primus will provide any art files needed for the documentation or DTP work.
4. That the English documentation given to EGS for Japanese translation will not

   such a change.

C. Delivery Schedule for Both Parties

EGS' ability to submit its deliverables to Primus on schedule is directly
dependent on Primus providing EGS with the needed deliverables by the dates
specified in the attached project schedule document. In order to prevent any
confusion the deliverables for both parties are stated in the project schedule
document.

D.  Third Party Components

Unless otherwise agreed to, EGS shall not be responsible for localizing any part
of Primus' products which is based on a third party tool or component. EGS shall

compensate EGS for any costs associated with extra work which reasonably result
from an unspecified third party tool or component, and which Primus has approved
in writing in advance of their being incurred. All third party tools need to be
specified and provided by Primus.

E.  Training Availability
