                               PROSPECTUS SUMMARY


     This summary highlights selected information contained elsewhere in this
prospectus. This summary may not contain all of the information that you should
consider before investing in our common stock. You should carefully read the
entire prospectus, including "Risk Factors" and the financial statements, before
making an investment decision.


                                  OUR BUSINESS


     Broadbase develops and markets software that integrates and analyzes
customer information from Internet and traditional business channels, enabling
businesses to improve their customer acquisition, retention and profitability.
Broadbase EPM integrates and analyzes information from numerous points of
customer interaction, or touch points, to provide a comprehensive understanding
of the customer lifecycle from initial identification through acquisition and
retention. Our products then allow businesses to translate this analysis into
specific actions such as targeting profitable customers, personalizing customer
interactions and identifying opportunities to sell complementary or higher-end
products and services. By integrating, analyzing and acting on valuable customer
information, our products enable businesses to build long-lasting and profitable
customer relationships.



     The Internet is emerging as an important channel for businesses to interact
with their customers. As a result, traditional "bricks and mortar" companies are
adapting many of their business activities to the Internet. In addition, a new
class of Internet-only companies is rapidly emerging. Together, these companies
represent a new category of enterprise called the e-business. The rise of the
Internet as a new business channel has led to a dramatic increase in the number
of ways that businesses interact with their customers. Today, these include not
only traditional storefronts, catalogs and call centers, but also websites,
e-mail marketing campaigns and online customer service. The Internet has also
created a highly competitive environment for businesses, where customers can
easily switch among alternative product and service offerings. To maintain
customer loyalty in this environment, e-businesses need to develop a complete
understanding of individual customers to maximize the effectiveness of every
customer interaction.



     Broadbase EPM is a software solution that addresses this need. Broadbase
EPM consists of a suite of applications that are built on EPM/Foundation, our
software platform that provides comprehensive analytic capabilities. Broadbase
EPM integrates information that has traditionally been isolated in separate
systems designed to support specific types of customer interactions, such as
customer service and Internet-based sales. It provides decision-makers in sales,
marketing, customer service and e-commerce business functions with a more
comprehensive view of the customer. Each application provides these
decision-makers with analysis of customer information that is specifically
designed for their particular business function. Our solutions can generally be
deployed in less than 30 days, allowing our customers to quickly capture revenue
opportunities and achieve rapid return on investment. To date, over 80 customers
have licensed our products from us and our distributors and resellers, including
both traditional "bricks and mortar" companies such as Boeing, Hewlett-Packard
and United Airlines and Internet-only companies such as InsWeb and Mercata.



     We introduced EPM/Foundation in the fourth quarter of 1997, and began
offering our analytic applications in the third quarter of 1998. In May 1999, we
expanded our suite by introducing new applications designed for e-business. We
first recognized revenue from our products in 1998. Our revenues were $3.4
million in 1998 and $3.5 million in the six months ended June 30, 1999. We have
incurred net losses in each period since our inception and as of June 30, 1999
we had accumulated net losses of approximately $29.0 million.



     We incorporated in California in November 1995 under the name Broadbase
Information Systems, Inc., and plan to reincorporate in Delaware as Broadbase
Software, Inc. prior to this offering. Our address is 172 Constitution Drive,
Menlo Park, California 94025, and our telephone number is (650) 614-8300.

                                  RISK FACTORS


     Before you invest in our common stock, you should become aware of various
risks, including those described below. You should carefully consider these risk
factors, together with all of the other information included in this prospectus,
before you decide to purchase shares of our common stock. The risks and
uncertainties described below are not the only ones we face. Additional risks
and uncertainties not presently known to us or that we currently deem immaterial
may also impair our business operations.



                         RISKS RELATED TO OUR BUSINESS


OUR BUSINESS IS DIFFICULT TO EVALUATE BECAUSE OUR OPERATING HISTORY IS LIMITED


     We are still in the early stages of our development. Our revenue and income
potential is unproven and depends on emerging, rapidly changing markets and on
acceptance of products that we have only recently introduced. Because our
operating history is limited and our product offerings are evolving, it is
difficult to evaluate our business and our future prospects.



     We incorporated in November 1995, and from that date through December 1997
were in the development stage, conducting research and developing our initial
products. We have only recently begun licensing our products and deriving
revenue. In the fourth quarter of 1997, we introduced our first product,
EPM/Foundation, which was designed to enable organizations to build and manage
datamarts -- a system for storing, retrieving and managing data for a specific
business function or department -- to analyze their customer information. In the
third quarter of 1998, we began offering Broadbase EPM applications designed to
operate with EPM/ Foundation to provide analysis for customer relationship
management. In May 1999, we introduced Broadbase EPM applications designed for
Internet sales channels, Internet marketing and other customer-focused
e-business applications. We also released new versions of existing Broadbase EPM
applications in May 1999. Because we have only recently introduced our products,
it is difficult to predict whether our products will be accepted by the market
and the level of revenues we can expect to derive from sales of our products. As
a result, you should evaluate our chances of financial and operational success
in light of the risks, uncertainties, expenses, delays and difficulties
associated with starting a new business and having limited product sales, many
of which may be beyond our control.


OUR GROWTH DEPENDS ON MARKET ACCEPTANCE OF OUR RECENTLY INTRODUCED BROADBASE EPM
APPLICATIONS DESIGNED FOR INTERNET-BASED SYSTEMS


     We first introduced Broadbase EPM applications designed for Internet-based
systems in May 1999. We expect that our future growth will depend significantly
on revenue from licenses of these Broadbase EPM applications and related
services, which is subject to significant risks. These new applications are our
first products specifically designed for the emerging e-business market. To
date, two customers, InsWeb and Mercata, have licensed these e-business
applications. To date, revenue from licenses of our Broadbase EPM applications
have constituted only a minority of our revenues, and most of our license
revenue has been derived from licenses of EPM/Foundation. There are significant
risks inherent in the introduction of new products like our new e-business
applications. Market acceptance of these new applications will depend on the
growth of the market for e-business solutions. This growth may not occur. We
also cannot be certain that our new e-business applications will meet customer
performance expectations. If they do not meet customer expectations or the
market for these products fails to develop or develops more slowly than we
expect, our business would be harmed.



WE HAVE INCURRED LOSSES SINCE INCEPTION AND WE EXPECT TO INCUR LOSSES FOR THE
FORESEEABLE FUTURE



     We incurred net losses and losses from operations for each period from our
inception through the second quarter of 1999. As of June 30, 1999, we had
accumulated net losses of approximately $29.0 million (415% of our cumulative
revenue as of that date). We have not


                                        4
<PAGE>   8


achieved profitability and we expect to continue to incur substantial operating
losses for the foreseeable future. We expect to incur increasing sales and
marketing, research and development and general and administrative expenses. As
a result, we will need to significantly increase our revenue to achieve
profitability. While our revenue has grown significantly in 1999, our growth may
not continue at the current rate or at all.


WE EXPECT OUR QUARTERLY REVENUE AND OPERATING RESULTS TO FLUCTUATE


     Our revenue and operating results are likely to vary significantly from
quarter to quarter. The factors that affect our quarterly operating results
include:


     - the demand for our products, particularly our recently-introduced
       Broadbase EPM applications;


     - the size and timing of customer orders for our EPM/Foundation product,
       our Broadbase EPM applications and our professional services;



     - increased expenses for sales and marketing, product development and
       administration;



     - changes in the mix of sales between EPM/Foundation and the various
       Broadbase EPM applications we provide as well as the level of sales of
       professional services as compared to product licenses;



     - changes in the mix of our domestic and international sales; and



     - changes in general economic and market conditions.



Our quarterly revenue increased 208% from the first quarter of 1998 to the first
quarter of 1999 and increased 113% from the second quarter of 1998 to the second
quarter of 1999. We do not believe that these rates of growth are indicative of
the growth in revenues, if any, that we can expect in the future. Accordingly,
we believe that period-to-period comparisons of our operating results may not be
meaningful and you should not rely on these comparisons as an indication of our
future performance. Our operating results may fall below the expectations of
securities analysts and investors. In this event, the market price of our common
stock would likely fall.



OUR OPERATING EXPENSES ARE INCREASING AND WE WOULD NOT BE ABLE TO REDUCE THEM
QUICKLY, WHICH COULD RESULT IN LOWER THAN EXPECTED OPERATING RESULTS IF WE DO
NOT ACHIEVE EXPECTED REVENUE LEVELS



     We plan to significantly increase our operating expenses as we expand our
sales, marketing, research and development, professional services, customer
support and administrative groups. These expenses will be incurred before we
generate any revenues from this increased spending. If we do not significantly
increase revenues as a result of these efforts, we will not achieve
profitability. Our operating expenses are based on our expectations of future
revenues and are relatively fixed in the short term. As a result, we would not
be able to reduce spending quickly if our revenue is lower than we had
projected. Our ability to accurately forecast our quarterly revenue is limited
because of our limited operating history, the rapidly evolving nature of our
market and the sales cycle for our products, which can be long and
unpredictable. If our revenue falls below our expectations in any quarter, or if
we increase our spending ahead of our revenue growth, our operating results
would be lower than expected.


THE UNPREDICTABLE TIMING OF OUR SALES AND IMPLEMENTATION CYCLE MAKES IT
DIFFICULT TO FORECAST OUR OPERATING RESULTS


     Our products can have a long and unpredictable sales cycle. Consequently,
we face difficulty predicting the quarter in which sales to expected customers
will occur. This contributes to the uncertainty of our future operating results.
Potential customers often require


                                        5
<PAGE>   9


time to weigh the costs and benefits of our products compared to those of
in-house development and integration efforts. As a result, our sales cycle has
typically ranged from approximately two to four months, although it can take
longer.



     In a typical application license transaction, a portion of the
implementation of our products is performed by our professional services group,
which connects our products to the customer's systems and data sources. Upon
completion of that connection, no significant obligations remain with respect to
implementation, and we recognize the revenue related to that license. The actual
connection process can often be completed in approximately two to four weeks.
However, the timing of the commencement and completion of this connection
process is subject to factors that may be beyond our control, as this process
requires access to the customer's facilities and coordination with the
customer's personnel after delivery of the software. As a result, we typically
do not recognize the license revenue from an application license until one to
three months after our product is shipped to the customer. Uncertainty as to
when our product can be connected at the customer's facilities makes it more
difficult to forecast our operating results and can result in significant
variability in our period to period results.



WE NEED TO ATTRACT, TRAIN AND RETAIN ADDITIONAL QUALIFIED PERSONNEL IN A
COMPETITIVE EMPLOYMENT MARKET



     Our success depends on our ability to attract, train and retain qualified,
experienced employees. There is substantial competition for experienced
management, engineering, sales and marketing personnel, particularly in the
market segment in which we compete. If we are unable to retain our existing key
personnel, or to attract, train and retain additional qualified personnel, we
may experience inadequate levels of staffing to develop and sell our products
and perform services for our customers.



     We believe that our success will depend on the continued services of our
executive officers. Other than initial offer letters containing information
regarding compensation, the Company does not currently have employment
agreements with any of these individuals. As a result, these employees serve
"at-will" and may elect to pursue other opportunities at any time. The loss of
any of our executive officers could harm our business. Certain of our executive
officers joined us only recently and have had a limited time to work together.
We cannot assure you that they will be able to work effectively together to
manage our growth and continuing operations. Our Executive Vice President of
Applications and Engineering joined Broadbase in December 1998, our Executive
Vice President of Sales joined Broadbase in May 1999, and our Vice President of
Marketing joined Broadbase in July 1999. If we are unable to hire a qualified
Vice President of Marketing or expand our sales and marketing organizations in a
timely manner, our growth could be limited. See "Management" for more
information regarding our management personnel.



OUR BUSINESS WILL SUFFER IF WE DO NOT INCREASE MARKET AWARENESS OF OUR PRODUCTS
BY SIGNIFICANTLY EXPANDING OUR SALES CAPABILITIES



     We sell our products primarily through our direct sales force. We must
significantly expand our direct sales operations to increase market awareness of
our products and increase revenue. We cannot be certain that we will be
successful in these efforts. Our products and services require sophisticated
sales efforts. As a result, our ability to increase our direct sales operation
will depend on our ability to recruit, train and retain top sales people with
advanced sales skills and technical knowledge. There is a shortage of sales
personnel with these qualifications, and competition for qualified personnel is
intense in our industry.


     Prior to 1999, our sales force sold our EPM/Foundation product and
applications designed to provide analysis for customer relationship management.
The skills required to sell these products differ in many respects from the
skills required to sell applications designed for

                                        6
<PAGE>   10


Internet-based systems. Accordingly, the introduction of our new e-business
applications has required us to hire new sales personnel with these skills and
train existing personnel to sell these new applications. As a result, most of
our current direct sales force has been with us for a relatively short period.
During the first six months of 1999, we added nine direct sales representatives
to our direct sales force, which represents 45% of our total direct sales
representatives and 23% of our total sales personnel as of June 30, 1999. New
sales personnel require training and take time to achieve full productivity. If
we are unable to hire or retain qualified sales personnel, or if newly hired
personnel fail to develop the necessary skills or reach productivity more slowly
than anticipated, our business could be harmed.



WE ARE DEPENDENT ON STRATEGIC RELATIONSHIPS AND DISTRIBUTION RELATIONSHIPS THAT
MAY GENERALLY BE TERMINATED AT ANY TIME, AND IF OUR CURRENT AND FUTURE STRATEGIC
RELATIONSHIPS OR DISTRIBUTION RELATIONSHIPS ARE NOT SUCCESSFUL, OUR GROWTH MAY
BE LIMITED



     We rely on strategic relationships with a variety of companies which
generate leads for the sale of our products. These strategic relationships
include relationships with system integrators and consulting firms, vendors of
e-commerce and Internet software, vendors of software designed for customer
relationship management or for management of organizations' operational
information, technology and vendors of key technology platforms and demographic
data providers. If we cannot maintain successful strategic relationships or
cannot enter into additional strategic relationships, we may have difficulty
expanding the sales of our products and our growth may be limited. We believe
that many of our direct sales are the result of leads generated by vendors of
e-business and enterprise applications that work with our products. Our
strategic relationships are generally not documented in writing, or are governed
by agreements that can be terminated by either party with little or no prior
notice. Some of these agreements specify that payments are to be made by us to
these companies for providing us with qualifying customer leads. The generation
of leads to date by these companies has not generally satisfied the specified
criteria and therefore payments for leads have been immaterial in amount.



     In addition, we have relationships with distributors and resellers of our
products located in the United States, Japan and the Netherlands -- our indirect
sales channel. Sales through our indirect sales channel accounted for
approximately 28.7% of our total revenue for 1998 and 40.8% for the six months
ended June 30, 1999. Sales of our products to Indus, which integrates
EPM/Foundation into certain of its enterprise solutions for the energy and
utility industries, represented 18.4% of our total revenue in 1998 and 11% in
the first six months of 1999. Substantially all of our sales in Japan have been
made through distributors. If we cannot maintain successful relationships with
our indirect sales channel, we may have difficulty expanding the sales of our
products and our growth may be limited.



     Companies with which we have a strategic or distribution relationship may
promote products of several different companies, including, in some cases,
products that compete with our products. These companies may not devote adequate
resources to selling our products. We may not be able to maintain these
relationships and enter into additional relationships that will provide timely
and cost-effective customer support and service. See "Business -- Strategic
Relationships" and "Sales and Marketing" for a description of these
relationships.



CUSTOMER SATISFACTION AND DEMAND FOR OUR PRODUCTS WILL DEPEND ON OUR ABILITY TO
EXPAND OUR PROFESSIONAL SERVICES GROUP, WHICH ASSISTS OUR CUSTOMERS WITH THE
IMPLEMENTATION OF OUR PRODUCTS



     We believe that growth in our product sales depends on our ability to
provide our customers with professional services to assist with support,
training, consulting and initial implementation of our products and to educate
third-party systems integrators in the use of our products. As a result, we plan
to increase the number of professional services personnel to


                                        7
<PAGE>   11


meet these needs. New professional services personnel will require training and
take time to reach full productivity. We may not be able to attract or retain a
sufficient number of highly qualified professional services personnel.
Competition for qualified professional services personnel with the appropriate
knowledge is intense. We are in a new market and there is a limited number of
people who have the necessary skills. To meet our customers' needs for
professional services, we may also need to use more costly third-party
consultants to supplement our own professional services group. In addition, we
could experience delays in recognizing revenue if our professional services
group falls behind schedule in connecting our products to customers' systems and
data sources.


WE MAY BE UNABLE TO ATTRACT NEW CUSTOMERS IF WE DO NOT DEVELOP NEW PRODUCTS AND
ENHANCEMENTS

     If we do not continue to improve our products and develop new products that
keep pace with competitive product introductions and technological developments,
satisfy diverse and rapidly evolving customer requirements and achieve market
acceptance, we may be unable to attract new customers. For example, we are
developing new applications as well as new versions of a number of our existing
applications, which are scheduled for release in the second half of 1999. We may
not be successful in developing and marketing these applications and new
versions, or other product enhancements and new products that respond to
technological advances and market changes, on a timely or cost-effective basis.
In addition, even if these products are developed and released, they may not
achieve market acceptance. We have in the past experienced delays in releasing
new products and product enhancements and may experience similar delays in the
future. These delays or problems in the installation or implementation of our
new releases may cause customers to forego purchases of our products.


MARKET ACCEPTANCE OF OUR PRODUCTS MAY SUFFER IF WE ARE UNABLE TO KEEP PACE WITH
RAPID TECHNOLOGICAL CHANGES IN OUR INDUSTRY



     Rapidly changing technology and operating system standards may impede
market acceptance of our products. Our new Broadbase EPM applications have been
designed based upon currently prevailing Internet technology. If new Internet
technologies emerge that are incompatible with Broadbase EPM applications, our
key products may become obsolete and our existing and potential customers may
seek alternatives to our products. We may not be able to quickly adapt our
products to any new Internet technology.



     Additionally, we have designed our products to work with databases such as
Oracle and Microsoft SQL Server. Any changes to those databases, or increasing
popularity of other databases, could require us to modify our products, and
could cause us to delay releasing future products and enhancements. Furthermore,
software adapters are necessary to integrate our products with other systems and
data sources used by our customers. We must develop and update these adapters to
reflect changes to these systems and data sources in order to maintain the
functionality provided by our products. As a result, uncertainties related to
the timing and nature of new product announcements, introductions or
modifications by vendors of operating systems, databases, customer relationship
management software, web servers and other enterprise and Internet-based
applications could delay our product development, increase our product
development expense or cause customers to delay evaluation, purchase and
deployment of our products.



WE ARE DEPENDENT ON THE ACCEPTANCE AND USE OF THE WINDOWS NT OPERATING SYSTEM



     Our products currently run only on the Windows NT operating system. Any
change to this operating system could require us to modify our products and
could cause us to delay product releases. Any decline in the market acceptance
of the Windows NT operating system for any reason, including as a result of
errors or delayed introduction of enhancement or upgrades,


                                        8
<PAGE>   12


could seriously harm us. If potential customers do not want to use the Windows
NT operating system, we will need to develop products that run on other
operating systems such as UNIX.



     The development of new products in response to these risks would require us
to commit a substantial investment of resources, and we may not be able to
successfully develop or introduce such products on a timely or cost-effective
basis, or at all, which could lead potential customers to choose alternatives to
our products.


WE FACE INTENSE COMPETITION WHICH COULD MAKE IT DIFFICULT TO ACQUIRE AND RETAIN
CUSTOMERS


     Our market is intensely competitive, and we expect competition to intensify
in the future. Our failure to maintain and enhance our competitive position
could seriously harm our business. Our customers' requirements and the
technology available to satisfy those requirements are continually changing.
Therefore, we must be able to respond to these changes in order to remain
competitive. Our competitors vary in size and in the scope and breadth of
products and services offered.



     We have three primary sources of competition:



     - providers of consulting services-based analysis solutions, such as
       E.piphany;


     - vendors of point solutions that provide website analysis, such as Accrue,
       Andromedia and Net Perceptions; and

     - in-house development efforts by potential customers using traditional or
       generic decision support tools.


     In addition, we face potential competition from vendors of other enterprise
applications as they expand the functionality of their product offerings,
including companies that design software for decision support, management of
customer relationships or of organizations' operational information, as well as
vendors of database applications. Accordingly, it is possible that new
competitors may emerge and acquire our market share.



     Some of our current and potential competitors have longer operating
histories and significantly greater financial, technical, marketing and other
resources than we do, and thus may be able to respond more quickly to new or
changing opportunities, technologies and customer requirements. Also, many
current and potential competitors have wider name recognition and more extensive
customer bases that they could leverage, thereby gaining market share to our
detriment. They may be able to undertake more extensive promotional activities,
adopt more aggressive pricing strategies, and offer purchasers more attractive
terms than we can. Our competitors may develop products that are superior to
ours or that achieve greater market acceptance. In addition, current and
potential competitors may establish cooperative relationships among themselves
or with third parties to enhance their products to address customer needs.


     Competitive pressures may make it difficult for us to acquire and retain
customers and may require us to reduce the price of our products. We cannot be
certain that we will be able to compete successfully with existing or new
competitors. If we fail to compete successfully against current or future
competitors, our business would be seriously harmed.


WE DEPEND ON OUR INTELLECTUAL PROPERTY, AND LITIGATION REGARDING OUR
INTELLECTUAL PROPERTY COULD HARM OUR BUSINESS



     Our intellectual property is important to our business. Our intellectual
property includes our proprietary technology, our trade secrets, copyrights in
our software and our trademarks. We have no patents or pending patent
applications, although patents may become increasingly important in software and
e-business applications. Unauthorized use or misappropriation of our


                                        9
<PAGE>   13


intellectual property could seriously harm our business. Third parties may
infringe upon our intellectual property rights, and we may be unable to detect
this unauthorized use or effectively enforce our rights. In addition, any legal
action that we may bring to protect our intellectual property rights could be
expensive and distract management from day-to-day operations.



     Our business activities may infringe upon the proprietary rights of others,
and other parties may assert infringement claims against us. For example, on
July 21, 1999, Timeline, Inc. filed a complaint against us in the United States
District Court for the Western District of Washington, alleging infringement by
us of U.S. Patent No. 5,802,511 held by Timeline. Timeline alleges that we
directly and indirectly infringe its patent claims by making, using, selling and
offering to sell software products, both alone and in combination with third
party software products, and further alleges that we induce infringement of the
Timeline patent claims. Timeline has requested permanent injunctions prohibiting
us from directly or indirectly infringing the Timeline patent, and seeks
damages, exemplary damages, costs and attorneys' fees. Timeline has further
disclosed to us patent claims of a pending related patent application that
Timeline expects to be issued and to be added to the present case. Based on our
investigation of this matter to date, we believe that we do not infringe any
valid claims of the Timeline patent or of the pending patent application, and
that we have other meritorious defenses to all claims made by Timeline.
Accordingly, we intend to defend this suit vigorously. Nevertheless, it is
possible that we could be found liable for infringing the Timeline patent.



     In addition, in the future, we may receive communications from other
parties asserting that our intellectual property infringes their proprietary
rights. If we become liable to Timeline or any other third party for infringing
its intellectual property rights, we could be required to pay substantial damage
awards and to develop non-infringing technology, obtain licenses or cease
selling the applications that contain the infringing intellectual property. We
may be unable to develop non-infringing technology or obtain licenses on
commercially reasonable terms, if at all. In addition, our defense of the
Timeline litigation and any other litigation, regardless of the merits of the
complaint, will likely be time-consuming, costly and a distraction for our
management personnel.


FAILURE TO LICENSE NECESSARY THIRD PARTY SOFTWARE INCORPORATED IN OUR PRODUCTS
MAY CAUSE DELAYS OR REDUCTIONS IN OUR SALES


     We currently rely on software that we have licensed from a number of
suppliers. These licenses may not continue to be available to us on commercially
reasonable terms or at all. In the future, we expect to license other third
party technologies to enhance our products, to meet evolving customer needs or
to adapt to changing technology standards. Failure to license, or the loss of
any license of necessary technologies, could result in delays or reductions of
shipments of our products until equivalent software is identified, licensed and
integrated or developed by us. If customers require the features provided by a
technology when licenses for that technology are not available, customers may
delay or decline to purchase our products. In addition, we may fail to
successfully integrate licensed technology into our products, which could
similarly delay or harm product development and market acceptance.


SOFTWARE DEFECTS COULD LEAD TO LOSS OF REVENUE OR DELAY IN MARKET ACCEPTANCE FOR
OUR PRODUCTS


     Our software products are internally complex and may contain defects,
especially when they are first introduced or when new versions are released. In
the past we have discovered software errors in some of our products after their
introduction. If we are not able to detect and correct errors in products or
releases before commencing commercial shipments, we may experience loss of
revenue or delays in market acceptance for our products. We continue to evaluate
our products for errors following the commencement of commercial shipments and
receive information from customers regarding errors they detect, as well as
requests for future


                                       10
<PAGE>   14


enhancements to our products. Our license agreements with our customers
typically contain provisions designed to limit our exposure to potential product
liability claims. However, all domestic and international jurisdictions may not
enforce these limitations. We may encounter product liability claims in the
future. Product liability claims brought against us could divert the attention
of management and key personnel, could be expensive to defend and may result in
adverse settlements and judgments.



BARRIERS TO INTERNATIONAL EXPANSION COULD LIMIT OUR FUTURE GROWTH



     We intend to expand our international operations, but we may face
significant barriers to this expansion. Our failure to manage our international
operations effectively could limit the future growth of our business.
International sales represented approximately 5.1% of our total revenue for the
year ended December 31, 1998 and 23.6% of our total revenue in the first six
months of 1999, substantially all of which consisted of sales of EPM/Foundation
to customers in Japan. We conduct our international sales primarily through
direct sales offices in Germany, the Netherlands and the United Kingdom, and
through distributors in Japan. The expansion of our existing international
operations and entry into additional international markets will require
significant management attention and financial resources.



     Our international operations face numerous risks. Our products must be
localized -- customized to meet local user needs -- in order to be sold in
particular foreign countries. Developing local versions of our products for
foreign markets is difficult and can take longer than we anticipate. We
currently have limited experience in localizing products and in testing whether
these localized products will be accepted in the targeted countries. For
example, we are currently marketing localized products only in Japan, and we
have only recently begun to develop products for sale in Germany. We cannot
assure you that our localization efforts will be successful. In addition, we
have only a limited history of marketing, selling and supporting our products
and services internationally. As a result, we must hire and train experienced
personnel to staff and manage our foreign operations. However, we may experience
difficulties in recruiting and training an international staff. We must also be
able to enter into strategic relationships with companies in international
markets, particularly in Japan where all of our sales have been made through
distributors. If we are not able to maintain successful strategic relationships
internationally or recruit additional companies to enter into strategic
relationships, our future growth could be limited.


     We also face certain other risks inherent in conducting business
internationally, such as:

     - difficulties and costs of staffing and managing international operations;

     - language and cultural differences;

     - difficulties in collecting accounts receivable and longer collection
       periods;

     - seasonal business activity in certain parts of the world;

     - fluctuations in currency exchange rates;

     - legal and governmental regulatory requirements;

     - trade barriers; and

     - potentially adverse tax consequences.

Any of these factors could seriously harm our international operations and,
consequently, our business.

     To date, a majority of our international revenue and costs have been
denominated in foreign currencies. We have not engaged in any foreign exchange
hedging transactions, and we are therefore subject to foreign currency risk.

                                       11
<PAGE>   15


WE ARE GROWING RAPIDLY, AND THE FAILURE TO MANAGE OUR GROWTH, INCLUDING
EXPANSION OF OUR MANAGEMENT SYSTEMS, COULD ADVERSELY AFFECT OUR BUSINESS



     We have grown rapidly and will need to continue to grow in all areas of
operation in order to execute our business strategy. Our total number of
full-time employees grew from 41 at December 31, 1997 to 105 at June 30, 1999,
and we anticipate further significant increases in the number of our employees.
Our growth has placed significant demands on management as well as on our
administrative, operational and financial resources and controls. We expect our
future growth to cause similar, and perhaps increased, strain on our systems and
controls. In particular, we need to substantially upgrade our information
systems including accounting and order entry. We also will need to institute new
systems such as human resource management and time and billing systems. If we
cannot effectively establish and improve our processes, we may not be able to
manage our growth successfully or sustain and manage the growth rates we have
experienced in the past.



OUR PROSPECTS FOR OBTAINING ADDITIONAL FINANCING, IF REQUIRED, ARE UNCERTAIN AND
FAILURE TO OBTAIN NEEDED FINANCING COULD AFFECT OUR ABILITY TO PURSUE FUTURE
GROWTH



     We expect our net proceeds from this offering, cash on hand, cash
equivalents, credit facilities and proceeds from our recent preferred stock
financing to meet our working capital and capital expenditure needs for at least
the next 12 months. After that, we may need to raise additional funds to meet
our working capital needs, develop or enhance our products or services, to fund
expansion, to respond to competitive pressures or to acquire complementary
products, businesses or technologies. We cannot assure you that we would be able
to obtain additional financing on favorable terms, if at all. If we issue
additional equity securities, stockholders may experience additional dilution or
the new equity securities may have rights, preferences or privileges senior to
those of existing holders of common stock. If we cannot raise necessary
additional funds on acceptable terms, we may not be able to develop or enhance
our products, fund expansion, take advantage of future opportunities or respond
to competitive pressures or unanticipated requirements. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources" for a discussion of our future
capital requirements.



                         RISKS RELATED TO OUR INDUSTRY


POTENTIAL YEAR 2000 PROBLEMS MAY INVOLVE SIGNIFICANT TIME AND EXPENSE AND MAY
REDUCE OUR FUTURE SALES


     If our technology or technology developed by third parties which is
incorporated into our products or which interacts with our products, is not year
2000 compliant in a timely manner, our business could be seriously harmed. The
year 2000 problem exists because many currently installed computer systems and
software products electronically store dates using only the last two digits of
the calendar year. As a result, these systems may not be able to distinguish
whether "00" means 1900 or 2000, which may cause system failures or erroneous
results. Year 2000 problems could subject us to liability claims and disrupt our
operations and customers' purchasing patterns, any of which could harm our
business.



     Our products operate in complex network environments and directly or
indirectly interact with a number of other hardware and software systems that we
cannot adequately evaluate for year 2000 compliance. In addition, technology
developed by others and incorporated in our products could have year 2000
problems. We may face claims based on year 2000 problems in other companies'
products, or issues arising from the integration of multiple products within an
overall system. We may in the future be required to defend our products or
services in litigation or arbitration proceedings involving our products or
services related to year 2000 compliance


                                       12

issues, or to negotiate resolutions of claims based on year 2000 issues.
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 be expensive. In addition, we may
experience reduced sales of products as customers and potential customers put a
priority on correcting year 2000 problems and therefore defer purchases of our
products. Accordingly, demand for our products may be particularly volatile and
unpredictable for the remainder of 1999 and early 2000.



     We currently have no contingency plans in place to address the risks
associated with unremediated year 2000 problems, but we are currently developing
these plans and expect to have them in place in the third quarter of 1999. With
the exception of our accounting system and software on a few of the computers
used by our sales representatives to demonstrate our products, we believe that
virtually all of our internal information systems are currently year 2000
compliant. We are in the process of obtaining the necessary compliance upgrades
for the systems that are not already year 2000 compliant. If we do not complete
in a timely manner these compliance upgrades for our internal information
systems, our operations could be disrupted as a result of a temporary lack of
availability of our accounting systems and an inability of certain of our sales
representatives to engage in demonstrations of our products. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations -- Year
2000 Readiness" for more information about our potential year 2000 problems and
the measures that we have taken to address these problems.



WE DEPEND ON THE GROWTH IN THE USE OF THE INTERNET FOR OUR BUSINESS


     Our future success depends heavily on the increased acceptance and use of
the Internet for business. Although the Internet is experiencing rapid growth in
the number of users and traffic, this growth is a recent phenomenon and may not
continue. Furthermore, despite this growth in usage, the use of the Internet for
business transactions is relatively new. If use of the Internet for business
does not continue to increase or increases more slowly than expected, our
business would be seriously harmed. Consumers and businesses may reject the
Internet as a viable commercial medium, or be slow to adopt it, for a number of
reasons, including potentially inadequate network infrastructure, slow
development of enabling technologies, concerns about the security of
transactions and confidential information and insufficient commercial support.
The Internet infrastructure may not be able to support the demands placed on it
by increased Internet usage and bandwidth requirements. In addition, delays in
the development or adoption of new standards and protocols required to handle
increased levels of Internet activity, or increased governmental regulation,
could cause the Internet to lose its viability as a commercial medium. If these
or any other factors cause use of the Internet for business to slow or decline,
our business would be harmed. Even if the required infrastructure, standards,
protocols or complementary products, services or facilities are developed, we
may incur substantial expenses adapting our products to changing or emerging
technologies.

INCREASING GOVERNMENTAL REGULATION OF THE INTERNET COULD LIMIT THE MARKET FOR
OUR PRODUCTS


     A number of legislative and regulatory proposals under consideration by
federal, state, local and foreign governmental organizations may lead to laws or
regulations concerning various aspects of the Internet, such as user privacy,
taxation of goods and services provided over the Internet, pricing, content and
quality of products and services. Legislation could dampen the growth in
Internet usage and decrease or limit its acceptance as a communications and
commercial medium. If enacted, these laws and regulations could limit the market
for our products. In addition, existing laws could be applied to the Internet,
including consumer privacy laws. Legislation or application of existing laws
could expose companies involved in electronic commerce, or e-commerce, to
increased liability, which could limit the growth of e-commerce generally.


                                       13
<PAGE>   17

GOVERNMENT REGULATION OF THE COLLECTION AND USE OF PERSONAL DATA COULD REDUCE
DEMAND FOR OUR PRODUCTS


     Our products connect to and analyze data from various applications,
including Internet applications, that enable businesses to capture and use
information about their customers. Government regulation which limits our
customers' use of this information could reduce the demand for our products. A
number of jurisdictions have adopted, or are considering adopting, laws that
restrict the use of customer information from Internet applications. The
European Union has required that its member states adopt legislation that
imposes restrictions on the collection and use of personal data on the Internet,
and that limits the transfer of personally-identifiable data to countries that
do not impose equivalent restrictions. In the United States, the Children's
Online Privacy Protection Act was enacted in October 1998. This legislation
directs the Federal Trade Commission to regulate the collection of data from
children on commercial websites. In addition, the Federal Trade Commission has
begun investigations into the privacy practices of businesses that collect
information on the Internet. These and other privacy-related initiatives could
reduce demand for some of the Internet applications with which our products
operate, and could restrict the use of our products in some e-commerce
applications. This could reduce demand for our products.



                         RISKS RELATED TO THIS OFFERING


OUR STOCK PRICE MAY BE VOLATILE WHICH COULD LEAD TO LOSSES BY INVESTORS AND TO
SECURITIES LITIGATION

     Our common stock has never been sold in a public market. An active trading
market for our common stock may not develop or be sustained after completion of
this offering. We will negotiate and determine the initial public offering price
with the representatives of the underwriters based on several factors. See
"Underwriting." The initial public offering price may not be indicative of the
prices that will prevail in the public market after this offering, and the
market price of the common stock could fall below the initial public offering
price.

     The value of your investment in Broadbase could decline due to the impact
of any of the following factors upon the market price of our common stock:

     - variations in our actual and anticipated operating results;

     - changes in our earnings estimates by analysts;

     - our failure to meet analysts' performance expectations; and

     - lack of liquidity.


     In addition, stock markets, particularly the Nasdaq National Market, have
experienced extreme price and volume fluctuations, and the market prices of
securities of technology companies, particularly Internet-related companies,
have been highly volatile. These fluctuations have often been unrelated to the
operating performance of such companies. Fluctuations such as these may affect
the market price of our common stock. Substantial sales of our common stock
after this offering could also cause our stock price to decline. As a result,
investors may not be able to resell their shares at or above the initial public
offering price.


     In the past, securities class action litigation has often been instituted
against companies following periods of volatility in their stock price. This
type of litigation could result in substantial costs and could divert our
management's attention and resources.


OUR OFFICERS, DIRECTORS AND MAJOR STOCKHOLDERS WILL HAVE SIGNIFICANT CONTROL
OVER US WHICH COULD DELAY OR PREVENT A CHANGE OF CONTROL



     Our executive officers, directors and major stockholders will have
significant control over us following completion of this offering as they will
beneficially own an aggregate of approximately 66.8% of our outstanding common
stock at that time. This could limit the ability of our other stockholders to
influence matters requiring approval by our stockholders, including the election


                                       14
<PAGE>   18


of directors and the approval of mergers or similar transactions. See "Principal
Stockholders" for information regarding the shares beneficially owned by our
executive officers, directors and major stockholders.



WE HAVE ADOPTED ANTI-TAKEOVER DEFENSES THAT COULD DELAY OR PREVENT THE SALE OF
OUR COMPANY AND DIMINISH THE VOTING RIGHTS OF THE HOLDERS OF OUR COMMON STOCK



     Provisions of our certificate of incorporation, bylaws and Delaware law
could make it more difficult for a third party to acquire us, even if doing so
would be beneficial to our stockholders. For example, we have a classified board
of directors. In addition, our stockholders are unable to act by written consent
or to fill any vacancy on the board of directors. In addition, our stockholders
cannot call special meetings of stockholders for any purpose, including to
remove any director or the entire board of directors without cause. We will also
be subject to the provisions of Section 203 of the Delaware General Corporation
Law regulating corporate takeovers. These provisions could also limit the price
that investors might be willing to pay in the future for shares of our common
stock. See "Description of Capital Stock" for a description of these provisions.


WE HAVE BROAD DISCRETION TO USE THE PROCEEDS FROM THIS OFFERING, AND OUR
INVESTMENT OF THESE PROCEEDS MAY NOT YIELD A FAVORABLE RETURN


     Our management has broad discretion as to how to spend the proceeds from
this offering and may spend these proceeds in ways with which our stockholders
may not agree. Pending any such uses, we plan to invest the net proceeds of this
offering in short-term, investment-grade, interest-bearing securities. These
investments may not yield a favorable return.



FUTURE SALES OF SHARES OF OUR COMMON STOCK COULD CAUSE THE PRICE OF OUR SHARES
TO DECLINE



     If our stockholders sell substantial amounts of our common stock in the
public market following this offering, the market price of our common stock
could decline. These sales also might make it more difficult for us to sell
equity or equity-related securities in the future at a time and price that we
deem appropriate. Based upon the number of our shares outstanding as of June 30,
1999, upon completion of this offering, we will have outstanding 17,203,690
shares of common stock, assuming no exercise of outstanding options or warrants
after June 30, 1999. Of these shares, the 4,000,000 shares sold in this offering
will be freely tradable, 10,284,667 additional shares of common stock will be
available for sale in the public market 180 days after the date of this
prospectus following the expiration of lock-up agreements, and 2,919,023 more
shares will become available for sale in the public market on subsequent dates.
These stockholders may be released from their lock-up agreements at any time and
without notice, which would allow for the earlier sale of shares in the public
market.



     After this offering, the holders of approximately 9,991,146 million shares
of common stock, which represent 58% of our outstanding stock after completion
of this offering, will be entitled to certain rights to have the resale of their
shares registered under the Securities Act of 1933. If these holders cause a
large number of securities to be registered and sold in the public market, such
sales could result in a significant decline in the market price for our common
stock.



YOU WILL INCUR IMMEDIATE AND SUBSTANTIAL DILUTION IN THE BOOK VALUE OF YOUR
INVESTMENT



     The initial public offering price is substantially higher than the pro
forma net book value per share of the outstanding common stock. If you purchase
shares of our common stock, you will incur immediate and substantial dilution in
the amount of $8.16 per share. If the holders of outstanding options or warrants
exercise those options or warrants, you will experience further dilution.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
                               AND INDUSTRY DATA


     We make many statements in this prospectus under the captions "Prospectus
Summary," "Risk Factors," "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business" and elsewhere that are
forward-looking and are not based on historical facts. These statements relate
to our future plans, objectives, expectations and intentions. We may identify
these statements by the use of words such as "believe," "expect," "anticipate,"
"intend" and "plan" and similar expressions. These forward-looking statements
involve a number of risks and uncertainties. Our actual results could differ
materially from those anticipated in these forward-looking statements as a
result of various factors, including those we discuss in "Risk Factors" and
elsewhere in this prospectus. These forward-looking statements speak only as of
the date of this prospectus, and we caution you not to rely on these statements
without also considering the risks and uncertainties associated with these
statements and the Company's business that are addressed in this prospectus.



     This prospectus contains estimates of market growth related to the
Internet. These estimates have been included in studies published by Forrester
Research, a market research firm. These estimates assume that certain events,
trends and activities will occur. If Forrester Research is wrong about any of
their assumptions, then their market estimates may also be wrong.

                                USE OF PROCEEDS


     The net proceeds to us from the sale of the 4,000,000 shares of common
stock offered by us will be approximately $43.6 million, at an assumed initial
public offering price of $12.00 per share and after deducting estimated
underwriting discounts and commissions and offering expenses. If the
underwriters' over-allotment option is exercised in full, our net proceeds will
be approximately $50.3 million. We intend to use the net proceeds from this
offering primarily for general corporate purposes, including working capital. We
may also use a portion of the net proceeds from this offering to acquire or
invest in businesses, technologies or services that are complementary to our
business. We have no present plans or commitments and are not engaged in any
negotiations with respect to any transactions of this type.


     We have not identified any specific uses for the net proceeds from this
offering, and we will have discretion over their use and investment. Pending use
of the net proceeds, we intend to invest the net proceeds from this offering in
short-term, interest-bearing, investment-grade securities. See "Risk
Factors -- We have broad discretion to use the proceeds from this offering, and
our investment of these proceeds may not yield a favorable return."

                                DIVIDEND POLICY


     We have never declared or paid any cash dividends on shares of our capital
stock. We intend to retain any future earnings to finance future growth and do
not anticipate paying any cash dividends in the future. In addition, the terms
of our credit facility with Silicon Valley Bank restrict our ability to pay cash
dividends.

       result of our Delaware reincorporation; and



     - our pro forma capitalization as adjusted to reflect our receipt of the
       net proceeds from the sale of shares of common stock offered by us at an

                                    DILUTION


     Our pro forma net tangible book value as of June 30, 1999 was $22.5
million, or $1.70 per share of common stock. Pro forma net tangible book value
per share represents the amount of our total tangible assets less total
liabilities, divided by 13,203,690 shares of common stock outstanding as of June
30, 1999 after giving effect to the conversion of all outstanding shares of
preferred stock and convertible debentures into shares of common stock upon
completion of this offering. After giving effect to the receipt of the net
proceeds from the sale of 4,000,000 shares of our common stock at an assumed
initial public offering price of $12.00 per share and after deducting estimated
underwriting discounts and commissions and the estimated offering expenses, our
pro forma net tangible book value as of June 30, 1999 would have been
approximately $66.1 million, or $3.84 per share. This represents an immediate
increase in pro forma net tangible book value of $2.14 per share to existing
stockholders and an immediate dilution of $8.16 per share to new investors
purchasing shares at the initial public offering price. The following table
illustrates this per share dilution:

     The above discussion and tables assume no exercise of any stock options or

options and warrants outstanding to purchase a total of 2,050,013 shares of our
common stock with a weighted-average exercise price of $0.65 per share. If any
of these options or warrants are exercised, there will be further dilution to
new public investors. Please see Notes 5 and 9 of Notes to Financial Statements
for more information about these options and warrants.

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

     The following discussion and analysis of our financial condition and
results of operations should be read in conjunction with "Selected Consolidated
Financial Data" and our consolidated financial statements and related notes
appearing elsewhere in this prospectus. This discussion and analysis contains
forward-looking statements that involve risks, uncertainties and assumptions.
The actual results may differ materially from those anticipated in these
forward-looking statements as a result of certain factors, including but not
limited to those set forth under "Risk Factors" and elsewhere in this
prospectus.

OVERVIEW


     We incorporated in November 1995 and from that date through December 1997
were in the development stage, conducting research and developing our initial
products. In the fourth quarter of 1997, we introduced EPM/Foundation. This
software product was originally designed to enable organizations to build and
manage datamarts for their customer information. In the third quarter of 1998,
we began offering Broadbase/EPM applications, built on EPM/ Foundation, which
provide analysis for customer relationship management. In May 1999 we expanded
our Broadbase/EPM suite by introducing new applications designed for Internet
sales channels, Internet marketing and other customer-focused e-business
applications, as well as new versions of our existing applications. As a result,
most of our license revenue through the first six months of 1999 has been
derived from licenses of EPM/Foundation. Throughout these periods, we expanded
our organization by hiring personnel in key areas, particularly marketing, sales
and research and development. We have grown from a total of 41 full-time
employees at December 31, 1997 to 75 full-time employees at December 31, 1998
and 105 full-time employees at June 30, 1999, and we intend to continue to
increase our number of employees throughout 1999.



     Our revenue comes principally from licenses of our software products, with
the balance coming from maintenance and professional services. We adopted the
provisions of Statement of Position ("SOP") No. 97-2 Software Revenue
Recognition, as amended by SOP No. 98-4, Deferral of the Effective Date of
Certain Provisions of SOP No. 97-2. Under SOP No. 97-2 we recognize license
revenue when persuasive evidence of an agreement exists, delivery of the product
has occurred, no significant company obligations with regard to installation or
implementation of the software remain, the fee is fixed or determinable and
collectibility is probable. In a typical application license transaction, our
professional services group connects our product to the customer's systems and
data sources. Upon completion of that connection, no significant obligations
remain with respect to implementation, and we recognize the revenue related to
that license. The actual connection process can often be completed in two to
four weeks. However, the timing of the commencement and completion of this
process is subject to factors that may be beyond our control, as this process
requires access to the customer's facilities and coordination with the
customer's personnel following delivery of the software. As a result, we
typically do not recognize the license revenue from an application license until
one to three months after our product is shipped to the customer. License
revenue generated by distributors and other resellers is recognized upon receipt
of a reseller report of sale and our shipment of the licensed software.
Maintenance and support revenue associated with new product licenses and
maintenance revenue resulting from renewed maintenance contracts are deferred
and recognized ratably over the contract period. Professional services revenue
is recognized when services are performed.



     Currently, businesses that license our products generally license one or
more Broadbase EPM applications, together with EPM/Foundation and adapters to
interface with the customers' existing data sources. Customers generally receive
a nonexclusive, perpetual license to use our


                                       22
<PAGE>   26

products for a specified number of servers and named concurrent users. After the
initial license, they may purchase licenses for additional servers and users as
needed. In addition, customers often purchase professional services from us,
including training services, although they may use other consulting
organizations. Customers that license our products also usually purchase
maintenance contracts, which provide software upgrades and technical support
over a stated term, typically 12 months.


     We sell our products through our direct sales force and through indirect
sales channels. Direct sales are made by our direct sales force in North
America, Germany, the United Kingdom and the Netherlands. Our indirect sales
channels include software application vendors, resellers and distributors
located in the United States, Japan and the Netherlands. Sales through indirect
sales channels accounted for approximately 28.7% of our total net revenue for
1998 and 40.8% for the six months ended June 30, 1999. Although a significant
portion of our revenue to date has been generated by our indirect sales
channels, we intend to continue increasing the size of our direct sales force,
both in the United States and internationally.



     Revenue from customers outside North America represented 5.1% of our total
net revenue for 1998 and 23.6% for the six months ended June 30, 1999.
Substantially all of our international revenue has been derived from sales of
EPM/Foundation by our distributors in Japan. We intend to continue to expand our
international operations and commit significant management time and financial
resources to developing our direct and indirect international sales channels.
International revenue may not, however, increase as a percentage of total net
revenue.



     We have experienced substantial net losses since our inception due to the
significant costs incurred to develop our technology and products and to recruit
and train personnel for our engineering, sales, marketing, professional services
and administration departments. As of June 30, 1999, we had an accumulated
deficit of $29.0 million. We expect to continue to incur substantial operating
losses for the foreseeable future.


RESULTS OF OPERATIONS

  NET REVENUE


     License. We began licensing our products in the first quarter of 1998.
License revenue increased from nothing in the period from inception through 1996
and nothing in 1997 to $3.0 million in 1998. License revenue increased from $1.3
million in the first six months of 1998 to $2.7 million in the first six months
of 1999, representing an increase of 100.7%. These increases in license revenue
are attributable to increases in the number of licenses sold, reflecting the
results of the expansion of our direct sales force and our indirect sales
channels. We intend to continue to expand both these channels. In addition, we
expect the average size of our revenue per license transaction to increase as a
result of our licensing Broadbase EPM applications as well as EPM/Foundation.


     Our license revenue decreased from the third quarter of 1998 to the fourth
quarter of 1998, as we transitioned to a direct sales force with the specific
skills required to sell our new Broadbase EPM applications for customer
relationship management.


     During 1998, we invested in developing our direct and indirect sales
channels as well as our maintenance and professional services groups. The result
of these efforts is reflected in the 48.4% increase in license revenue between
the fourth quarter of 1998 and the first quarter of 1999 and the steadily
increasing revenue from maintenance and professional services from the second
quarter of 1998 through the second quarter of 1999.


                                       23
<PAGE>   27


     Maintenance and professional services. Maintenance revenue is recognized on
a straight-line basis over the period support is provided, usually one year. We
first began recognizing maintenance revenue in the second quarter of 1998 for
maintenance contracts sold at the end of the first quarter of 1998. Professional
services revenue is recognized as the services are performed. Professional
services revenue was first recognized in the second quarter of 1998. Maintenance
and professional services revenue increased from nothing in the period from
inception through 1996 and nothing in 1997, to $443,000 in 1998 and increased
from $98,000 in the first six months of 1998 to $846,000 in the first six months
of 1999. The growth in maintenance and professional services revenue in the
first six months of 1999 compared to the same period of 1998 reflects the
expansion of our installed base of customers and the Company's increasing
emphasis on providing its customers with post-implementation consulting and
support.


  COST OF REVENUE


     Cost of licenses. The cost of licenses consists primarily of royalties paid
to third parties and the cost of product manuals, media, packaging and shipping.
The cost of licenses increased from nothing in the period from inception through
1996 and nothing in 1997 to $713,000 in 1998 and from $366,000 in the first six
months of 1998 to $428,000 in the first six months of 1999, primarily as a
result of increased license revenue. Our cost of licenses has varied
significantly from quarter to quarter. These variations are due primarily to
changes in the mix of products sold, since our products require payment of
royalties to third parties at differing rates.



     Cost of maintenance and professional services. The cost of maintenance and
professional services consists primarily of personnel costs associated with
providing maintenance and support services, consulting services and training
services. We began incurring costs associated with maintenance and support in
the second quarter of 1998 when support periods for our customers began, which
resulted in an increase from nothing in the period from inception through 1996
and nothing in 1997 to $254,000 in 1998 and from $83,000 in the first six months
of 1998 to $932,000 in the first six months of 1999. The increase in cost of
maintenance and professional services between the first six months of 1998 and
the first six months of 1999 was due primarily to the hiring of a vice president
of professional services and eight additional professional services personnel.
We plan to continue expanding our professional services group and, accordingly,
expect the dollar amount of our cost of maintenance and professional services to
increase.



     Sales and marketing. Sales and marketing expenses consist primarily of
salaries, benefits, bonuses, commissions, travel and promotional expenses and
the facilities cost for the various domestic and international field sales
offices. Sales and marketing expenses increased from $130,000 for the period
from inception through 1996 to $2.9 million in 1997 and to $7.9 million in 1998
and from $3.6 million in the six months of 1998 to $6.5 million in the first six
months of 1999. These increases in sales and marketing expenses resulted
primarily from higher salary, recruiting, benefits, travel and facilities costs
associated with the hiring of additional sales and marketing personnel and the
expansion of our international sales organization. Full time sales and marketing
personnel grew from 23 at June 30, 1998 to 44 at June 30, 1999. We plan to
continue expanding our sales and marketing organization, and expect our sales
and marketing expense to increase.



     Research and development. Research and development expenses consist
primarily of salaries for development personnel and related costs associated
with the development of new products, the enhancement of existing products,
localization, quality assurance and testing. Research and development expenses
increased from $928,000 in the period from inception through 1996 to $2.0
million in 1997 and to $3.7 million in 1998 and from $1.7 million in the first
six months of 1998 to $2.8 million in the first six months of 1999. These
increases in


                                       24
<PAGE>   28


research and development expenses were due to the hiring of additional personnel
and to other expenses associated with the development and localization of new
products. Full time research and development personnel grew from 25 at June 30,
1998 to 33 at June 30, 1999. We plan to continue expanding our research and
development organization, and expect our research and development expense to
increase.



     General and administrative. General and administrative expenses consist
primarily of salaries of executive, financial, human resource and information
services personnel as well as outside professional fees. General and
administrative expenses increased from $215,000 in the period from inception
through 1996 to $744,000 in 1997 and to $1.2 million in 1998 and from $522,000
in the first six months of 1998 to $932,000 in the first six months of 1999.
These increases in general and administrative expenses were primarily due to
increased staffing required to support our expanded operations in the United
States and abroad and, to a lesser extent, increased costs of outside
professional services and costs to implement additional management information
systems. Our full time general and administrative personnel grew from 8 at June
30, 1998 to 13 at June 30, 1999.



     Deferred compensation. We recorded deferred compensation of approximately
$3.5 million in 1998, representing the difference between the exercise prices of
options granted to acquire approximately 632,000 shares of common stock during
1998 and the deemed fair value for financial reporting purposes of our common
stock on the grant dates. We amortized deferred compensation expense of
approximately $1.1 million during 1998. This compensation expense relates to
options awarded to individuals in all operating expense categories. Total
deferred compensation at December 31, 1998 of approximately $2.3 million is
being amortized using a graded vesting method over the vesting periods of the
options. In addition, we granted options to purchase common stock in the first
six months of 1999 for which we recorded additional deferred compensation of
approximately $11.0 million which will be amortized using a graded vesting
method over the vesting periods of the options. The amortization of deferred
compensation recorded through June 30, 1999 will be approximately $6.0 million
for 1999, $4.2 million for 2000, $2.1 million for 2001, $897,000 for 2002 and
142,000 for 2003.



     Interest income. Interest income consists of interest earned on our cash
and cash equivalents. Interest income for the period from inception through 1996
was $30,000 and for 1997 was $154,000, representing interest earned on the cash
proceeds of our Series A and Series B preferred stock financings. Interest
income increased to $335,000 in 1998, due primarily to the investment of the
proceeds of our Series C preferred stock financing. Interest income increased
from $158,000 in the first six months of 1998 to $194,000 in the first six
months of 1999 due to higher invested cash balances in 1999 as a result of the
investment of proceeds received from the sale of $8.3 million and $1.3 million
of Series D convertible debentures in December 1998 and April 1999,
respectively.



     Interest expense. Interest expense consists primarily of interest on our
notes payable, bank line of credit and convertible debentures. Interest expense
increased from $29,000 for the period from inception through 1996 to $66,000 in
1997 due to $300,000 in additional borrowings in 1997 under notes from a
financial institution, and to $226,000 in 1998 due to $1.0 million in additional
borrowing in 1998 under a bank line of credit. Interest expense increased from
$100,000 in the first six months of 1998 to $561,000 in the first six months of
1999 due primarily to interest payments on $8.3 million of convertible
debentures issued in December 1998 and $1.3 million of convertible debentures
issued in April 1999.


     Income taxes. There was no federal income tax provision in any period
presented due to our net operating losses. We had deferred tax assets of
approximately $2.9 million as of December 31, 1997 and $6.5 million as of
December 31, 1998. Realization of deferred tax assets is dependent on future
earnings, if any, the timing and amount of which are uncertain.

                                       25
<PAGE>   29

Accordingly, a valuation allowance, in an amount equal to the net deferred tax
assets as of December 31, 1997 and 1998, has been established to reflect these
uncertainties. Our deferred tax assets primarily relate to net operating loss
and tax credit carryforwards. As of December 31, 1998, we had federal net
operating loss carryforwards of approximately $15.4 million and state net
operating loss carryforwards of approximately $10.7 million. We also had federal
and state research and development tax credit carryforwards of approximately
$300,000 and $200,000, respectively. The net operating loss and tax credit
carryforwards will expire at various dates beginning in 2004, if not utilized.
Utilization of the net operating loss and tax credit carryforwards may be
subject to a substantial annual limitation due to the "change in ownership"
provisions of the Internal Revenue Code of 1986 and similar state provisions.
The annual limitation may result in the expiration of net operating loss and tax
credit carryforwards before utilization.

LIQUIDITY AND CAPITAL RESOURCES


     Historically, we have funded our operations primarily through the sale of
equity securities, with net proceeds of $38.6 million, sales of convertible
debentures, with net proceeds of $9.5 million, and bank borrowings.



     Net cash used in operating activities was $4.8 million in 1997 and $6.1
million in 1998. Net cash used in operating activities was $6.4 million in the
six months ended June 30, 1999. In each period, net cash used in operating
activities resulted from our net loss offset in part by increases in current
liabilities, especially deferred revenue in 1998 and accrued expenses in the
first six months of 1999. The increase in deferred revenue consisted primarily
of prepayments of licenses from Japanese distributors and prepayment of
maintenance.



     Our investing activities used cash of $661,000 in 1997, $1.4 million in
1998 and $637,000 in the first six months of 1999. Net cash used in investing
activities in these periods was primarily the result of capital expenditures for
computer and communications equipment, purchased software, office equipment,
furniture, fixtures and leasehold improvements.



     Our financing activities provided cash of $1.1 million in 1997, $20.4
million in 1998 and $21.0 million in the first six months of 1999. In 1997,
financing activities provided cash primarily from issuance of $1.0 million of
long-term debt. In 1998, financing activities provided cash of $11.9 million
from the issuance of preferred stock, $8.3 million from the issuance of
convertible debentures and $1.0 million from borrowings under our bank credit
facility. This was offset in part by long-term debt repayment of $380,000 and a
$400,000 loan to an officer and stockholder in exchange for a non-recourse
promissory note which is secured by common stock of Broadbase held by the
officer. For the first six months of 1999, our financing activities provided
cash primarily from the issuance of $20.0 million of preferred stock and the
issuance of $1.3 million of convertible debentures.



     In July 1998, we entered into a loan and security agreement with Silicon
Valley Bank, providing a line of credit of up to $2.0 million and an equipment
line of credit of up to $1.0 million. Any borrowings under the line of credit
bear interest at the bank's prime lending rate, and any borrowings under the
equipment line of credit would bear interest at the bank's prime lending rate
plus 0.5%. As of June 30, 1999, borrowings under the line of credit would have
accrued interest at a rate of 7.75% and the borrowings under the equipment line
of credit accrued interest at a rate of 8.25%. Borrowings under this agreement
are secured by certain assets of Broadbase. As of June 30, 1999, no borrowings
were outstanding and $2.0 million was available for borrowing under the line of
credit. In addition, as of that date, $833,500 was outstanding under the
equipment line of credit. Borrowings under the equipment line of credit are due
in 36 equal monthly installments of principal, plus accrued interest, beginning
in January 1999 and ending in December 2001. The agreement contains covenants
requiring that we


                                       26
<PAGE>   30


satisfy certain financial ratios and maintain a minimum tangible net worth. The
agreement also prohibits us from paying cash dividends. As of December 31, 1998
and June 30, 1999, we were in compliance with these covenants. In addition, as
of June 30, 1999, we had outstanding indebtedness under two separate notes
payable to a financial institution aggregating $684,000, at a weighted-average
interest rate of 14.5% per year.



     As of June 30, 1999, we had $28.0 million of cash and cash equivalents
which, together with the proceeds from this offering and the $2.0 million
available for borrowing under our bank line of credit, will be sufficient to
fund our operations, including working capital and capital equipment purchase
requirements, through at least December 31, 2000. After that time, we intend to
fund our working capital and capital expenditure requirements from any remaining
cash and cash equivalents, cash generated from operating activities existing and
future bank financing, and possibly from future sales of our capital stock. We
cannot be certain that we would be able to obtain additional financing on
favorable terms, if at all. If we cannot raise necessary additional funds on
acceptable terms, we may not be able to develop or enhance our products, take
advantage of future opportunities or respond to competitive pressures or
unanticipated requirements. At June 30, 1999, we had no material commitments for
capital expenditures and $2.1 million of minimum lease payments under
noncancellable operating and capital leases, net of future sublease income under
noncancellable subleases.


QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISKS


     Our exposure to market risk for changes in interest rates relates primarily
to our long-term debt obligations. We primarily use proceeds from these debt
obligations to support general corporate requirements including capital
expenditures and working capital needs. We have interest rate exposure on
borrowings under our revolving line of credit and equipment line of credit which
bear interest at variable rates based on the prime interest rate. We have no
interest rate exposure on our convertible debentures and notes payable to a
financial institution, as the interest rates on these obligations are fixed.



     The table below presents principal amounts by year of maturity and related
weighted-average interest rates for our debt obligations as of December 31,
1998.

     We have no derivative financial instruments in our cash and cash
equivalents. We invest our cash and cash equivalents in investment grade, highly
liquid investments, consisting of money market instruments and bank certificates
of deposit. We anticipate investing our net proceeds from this offering in
similar investment grade and highly liquid investments pending their use as
described in this prospectus.

                                       27

     We are exposed to market risk from fluctuations in foreign currency
exchange rates. We manage exposure to variability in foreign currency exchange
rates primarily through the use of natural hedges, as both liabilities and
assets are denominated in the local currency. However, different durations in
our funding obligations and assets may expose us to the risk of foreign exchange
rate fluctuations. We have not entered into any derivative instrument
transactions to manage this risk. Based on our overall foreign currency rate
exposure at March 31, 1999, we do not believe that a hypothetical 10% change in
foreign currency rates would materially adversely affect our financial position.

As a result, these systems may not be able to distinguish whether "00" means
1900 or 2000, which may cause system failures or erroneous results. This problem
is generally referred to as the "year 2000 issue."


     State of readiness.  We have completed our assessment of the potential
overall impact of the impending century change on our business. Based on our
current assessment, we believe current and prior versions of our software
products are year 2000 compliant. By year 2000 compliant, we mean that the use
or occurrence of dates on or after January 1, 2000 will not materially affect
the performance of our software products or the ability of our products to
correctly create, store, process and output data involving dates, provided that
all other products, such as hardware and software used with our products, are
also year 2000 compliant. However, our products are generally integrated into,
and process data extracted from, other 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 even if our products are otherwise
year 2000 compliant.



     Utilizing a combination of an external consulting firm and our information
systems department personnel, we have completed an assessment of our internal
management information systems and other computer systems' readiness for year
2000 issues. As part of this effort, we have communicated with the external
vendors that supply us with our software and information systems and with our
significant suppliers to determine their products' and organization's year 2000
compliance. We received a written response from a small percentage of the
external vendors and significant suppliers that were contacted indicating that
their systems are year 2000 compliant. Those who have not responded have
statements on their web sites indicating that their systems are year 2000
compliant.



     The results of these readiness assessment initiatives indicate that, with
the exception of our accounting system and software on a few of the computers
used by our sales representatives to demonstrate our products, virtually all of
our internal information technology systems and other internal operating systems
are currently year 2000 compliant. For those non-compliant internal information
systems, we are in the process of obtaining the necessary compliance upgrades.
We plan to implement the necessary upgrades to these systems by September 30,
1999.



     Costs.  To date, costs directly associated with our year 2000 compliance
efforts have not been material, amounting to less than $20,000. These costs
consist of fees paid to an external consulting firm assisting us with our year
2000 readiness assessment initiatives as well as costs incurred for consultants
to assist in our remediation efforts. In addition, we have incurred expenses in
amounts that are not material 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. However, during


                                       28
<PAGE>   32


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 seriously harm our business. We currently have no
contingency plans in place to address the risks associated with unremediated
year 2000 problems but we are currently developing these plans and expect to
have them in place in the third quarter of 1999.



     Risks.  We are not currently aware of any year 2000 compliance problems
relating to our products that would seriously harm our business. We may discover
year 2000 compliance problems in our products that will require substantial
revision and could subject us to liability claims. Our products operate in
complex network environments and directly or indirectly interact with a number
of other hardware and software systems that we cannot adequately evaluate for
year 2000 compliance. In addition, technology developed by others and
incorporated in our products could have year 2000 problems. 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 even if our
products are otherwise year 2000 compliant. Our failure to fix or replace our
internally developed proprietary software or third-party software, hardware or
services on a timely basis could result in lost revenue, increased operating
costs, the loss of customers and other business interruptions, any of which
could seriously harm our business. Moreover, our failure to adequately address
year 2000 compliance issues in our internally developed proprietary software
could result in claims of mismanagement, misrepresentation or breach of contract
and related litigation, which could be costly and time-consuming to defend. In
particular, if we fail to complete in a timely manner the compliance upgrades to
our accounting systems and certain of the computers used to demonstrate our
products, our operations would be disrupted as a result of a lack of
availability of our accounting systems and an inability of certain of our sales
representatives to engage in demonstration of our products.


     In addition, governmental agencies, utility companies, Internet access
companies, third-party service providers and others outside of our control may
not be year 2000 compliant. The failure of these entities to be year 2000
compliant could result in a systemic failure beyond our control, such as a
prolonged Internet, telecommunications or electrical failure, which could also
prevent us from delivering our services to our customers, decrease the use of
the Internet or prevent users from accessing websites.

     Although we have not been a party to any litigation or arbitration
proceeding involving our products related to year 2000 compliance issues, we may
in the future be required to defend our products or services in these
proceedings, or to negotiate resolutions of claims based on year 2000 issues.
Defending and resolving year 2000-related disputes, regardless of the merits of
these disputes, and any liability we have for year 2000-related damages,
including consequential damages, could be expensive and could seriously harm our
business.

     We may experience reduced sales of products as customers and potential
customers put a priority on correcting year 2000 problems and therefore defer
purchases of our products. Accordingly, demand for our products may be
particularly volatile and unpredictable for the remainder of 1999 and early
2000. To the extent year 2000 issues cause a significant delay in, or
cancellation of, decisions to purchase our products or services, our business
would be seriously harmed.


     Contingency plan.  As discussed above, we are engaged in an ongoing year
2000 assessment and have not yet implemented any contingency plans. However, we
are currently developing these plans and expect to have them in place in the
third quarter of 1999. The


                                       29
<PAGE>   33


results of our year 2000 simulation testing and the responses received from
third-party vendors and service providers are being taken into account in
determining the nature and extent of any contingency plans we adopt.


NEW ACCOUNTING PRONOUNCEMENTS


     In March 1998, the Accounting Standards Executive Committee issued
Statement of Position 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use" ("SOP 98-1"). SOP 98-1 requires
companies to capitalize certain qualifying computer software costs which are
incurred during the application development stage and amortize them over the
software's estimated useful life. Broadbase was required to adopt SOP 98-1
effective January 1, 1999. The adoption of SOP 98-1 did not have a material
impact on Broadbase's consolidated financial position or results of operations.



     In April 1998, the AICPA issued SOP 98-5, "Reporting the Costs of Start-Up
Activities" ("SOP 98-5"). SOP 98-5 was effective beginning on January 1, 1999
and requires that start-up costs capitalized prior to January 1, 1999, be
written off, and any future start-up costs be expensed as incurred. The adoption
of SOP 98-5 did not have a material impact on Broadbase's consolidated financial
position or results of operations.



     In June 1998, the Financial Accounting Standards Board issued Financial
Accounting Standards Statement No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("FAS 133"). FAS 133 establishes methods of accounting
for derivative financial instruments and hedging activities related to those
instruments as well as other hedging activities. Broadbase will be required to
adopt FAS 133 for its year ending December 31, 2001. However, because Broadbase
does not utilize derivative financial instruments, it does not believe the
impact of FAS 133 will be material to its consolidated financial position or
results of operations.

     This prospectus contains forward-looking statements that involve risks and
uncertainties. Actual results may differ materially from those indicated in such
forward-looking statements.


     Broadbase develops and markets software that integrates and analyzes
customer information from Internet and traditional business channels, enabling
businesses to improve their customer acquisition, retention and profitability.
Broadbase EPM integrates and analyzes information from numerous points of
customer interaction, or touch points, to provide a comprehensive understanding
of the customer lifecycle from initial identification through acquisition and
retention. Our products then allow businesses to translate this analysis into
specific actions such as targeting profitable customers, personalizing customer
interactions and identifying opportunities to sell complementary or higher-end
products and services. By integrating, analyzing and acting on valuable customer
information, our products enable businesses to build long-lasting and profitable
customer relationships.



     Broadbase EPM consists of a suite of applications that are built on
EPM/Foundation, our software platform that provides comprehensive analytic
capabilities. Broadbase EPM integrates information that has traditionally been
isolated in separate systems designed to support specific types of customer
interactions, such as customer service and Internet-based sales. It provides
decision-makers in sales, marketing, customer service and e-commerce business
functions with a more comprehensive view of the customer. Each application
provides these decision-makers with analysis of customer information that is
specifically designed for their particular business function. Our solutions can
generally be deployed in less than 30 days, allowing our customers to quickly
capture revenue opportunities and achieve rapid return on investment. To date,
over 80 customers have licensed our products from us and our distributors and
OEMs, including both traditional "bricks and mortar" companies such as Boeing,
Hewlett-Packard and United Airlines and Internet-only companies such as InsWeb
and Mercata.


INDUSTRY BACKGROUND


     The recent emergence and acceptance of the Internet as a medium for
commerce is fundamentally changing the way companies communicate, obtain
information, purchase goods and transact business with their customers. The
Internet offers a number of compelling benefits that are causing increasing
numbers of companies to transact business online, including opportunities to
increase revenue, reduce operating costs and improve customer retention. As a
result, the Internet has become an important new channel for both traditional
"bricks and mortar" and Internet-only businesses to interact with and market and
sell to customers. Both types of companies are adapting many of their business
activities for the Internet, defining a new category of enterprise called the
e-business. Forrester Research estimates that the number of U.S. companies with
5,000 or more employees using the Internet as a channel for e-commerce will
increase from 20% in 1998 to 92% in 2002. Across companies of all sizes,
Forrester Research estimates that online business-to-business and
business-to-consumer transactions will grow from $127 billion in 1999 to over
$1.4 trillion in 2003.


     This rise of the Internet as a primary business channel has created a
highly competitive environment with low barriers to entry for new competitors
and insignificant switching costs for customers. Because customers have a
growing number of easily accessible choices both on and off the Internet,
e-businesses face a constant battle for customer loyalty. For example,
travelers, once limited to traditional travel agents, can now also choose among
numerous online providers at the click of a mouse. In this rapid paced Internet
environment, existing enterprise applications that automate processes and reduce
costs are no longer sufficient to build long lasting and profitable customer
relationships. In order to create these relationships, e-businesses must

                                       31
<PAGE>   35

target, convert and retain customers by differentiating their products and
services to meet each customer's individual requirements.

  PROLIFERATION OF CUSTOMER TOUCH POINTS


     As a result of this competitive environment, enterprises need to develop
customer-focused business models founded on a comprehensive understanding of
individual customer relationships. Traditionally, businesses have managed these
relationships by functional departments, such as marketing, sales and customer
support, and customer information has been isolated within these departments. In
contrast, e-businesses must integrate customer information across functional
departments to maximize the value of the entire customer lifecycle, from initial
identification through acquisition and retention. E-businesses need to analyze
and act on customer information gathered from all sources, including direct
sales organizations, storefronts, catalogs and websites. By using real time and
historic customer intelligence to personalize business relationships, successful
e-businesses can maximize loyalty and profitability throughout the customer
lifecycle.



     With the emergence of the Internet as a primary business channel, the
number of points of customer interaction, or touch points, has increased
dramatically. Internet sales systems, online customer service solutions, website
logs and e-mail management systems have multiplied the massive amounts of
customer interaction data already generated by conventional front office systems
such as sales force automation systems, telesales and customer support call
centers, marketing automation systems, and customer and field service
applications. In addition, traditional back office systems such as billing,
manufacturing and human resource systems, capture large volumes of important
customer and operational data. This increase in data sources makes the challenge
of integrating and analyzing the information generated throughout the customer
lifecycle more difficult. The sheer volume and variety of customer data creates
a competitive opportunity for businesses that can effectively integrate, analyze
and act on this information.


  NEED FOR COMPREHENSIVE E-BUSINESS ANALYTIC SOLUTIONS


     Traditionally, businesses tried to analyze this valuable data by piecing
together generic technologies -- point tools -- that address narrow and discrete
analytical needs. These point tools include data extraction tools to access
data, online analytical processing tools to analyze and model data, data mining
technologies to identify patterns in data, and report generators to present the
information. Piecing together these point tools to create a patchwork system
typically requires significant custom programming and takes a long time to
complete. In addition, these patchwork systems are very difficult and costly to
maintain. Because patchwork systems are inflexible and costly to maintain, they
are poorly suited to the rapidly changing business and technology requirements
of e-businesses.



     Moreover, patchwork systems and point tools cannot provide e-businesses
with a comprehensive understanding of the entire customer lifecycle. Instead,
they generally offer limited analysis based on a single element of a customer's
interaction with a business, focusing on a single channel, customer touch point
or period of time. For example, today's website monitoring tools completely
ignore historical customer activity across other channels, such as call centers
or traditional storefronts. As a result, these tools would not indicate that a
customer used the Internet to gather information about a product, purchased the
product at a physical store and later contacted customer support.


     Finally, patchwork systems and point tools do not enable e-businesses to
act quickly on data generated by customer interactions. These tools were not
designed for specific functions such as e-commerce or customer service, or their
unique underlying business processes. Because the data and reports generated by
point tools cannot be quickly translated into

                                       32
<PAGE>   36

concrete actions, they cannot unleash one of the most powerful potentials of
e-business -- the ability to personalize customer interactions and differentiate
product offerings in real time.


     Both multi-channel "bricks and mortar" and Internet-only businesses require
solutions that integrate, analyze and act on information from all customer touch
points. These analytic solutions must create a comprehensive view of the
customer lifecycle by integrating information from e-commerce and Internet-based
systems, front office systems, back office applications and external information
sources. They also must provide business users in different functional areas
with packaged applications that analyze this information using industry
benchmarks, business logic and guided decision-making capabilities. Finally,
e-businesses require solutions that enable them to move quickly from analysis to
action, enhancing customer relationships both online and offline.


OUR SOLUTION


     Our Broadbase EPM -- E-Business Performance Management -- solution consists
of two components: the EPM/Foundation software platform and the Broadbase EPM
suite of analytic applications. EPM/Foundation is a robust and extensible
software platform that integrates and analyzes customer interactions and
operational data from multiple sources. Our Broadbase EPM applications provide
decision-makers within various business functions with analysis of this
information to improve customer targeting, acquisition, conversion and
retention. Broadbase EPM applications are designed for the specific and changing
analytic needs of decision makers in e-commerce, online publishing and
advertising, marketing, sales and customer service functions. Our solutions are
designed to enable businesses to target customer segments, personalize marketing
promotions and campaigns, differentiate product and service offerings and
leverage operational resources, resulting in more loyal and profitable
customers.


     We believe our solutions represent an innovative and comprehensive approach
to analyzing and optimizing e-business customer interactions by providing the
following benefits:

  UNDERSTAND THE ENTIRE CUSTOMER LIFECYCLE


     Our Broadbase EPM solution integrates information from multiple channels
and customer touch points to provide a comprehensive view of the entire customer
lifecycle, from initial identification through acquisition and retention.
EPM/Foundation transforms, cleanses, loads and integrates large volumes of
customer and operational data, such as previous purchases, responses to
promotions and service requests. The Broadbase EPM applications then use this
integrated information to deliver function-specific analysis.


  IMPROVE CUSTOMER ACQUISITION, CONVERSION AND RETENTION RATES


     E-businesses that deploy our solutions use analysis of the entire customer
lifecycle to target, personalize and differentiate all aspects of online and
offline customer interactions -- moving beyond the simple automation of customer
transactions. For instance, businesses use our solutions to increase customer
acquisition by targeting higher value customers, to improve conversion rates by
personalizing web content and advertising, and to enhance customer retention by
streamlining customer service bottlenecks. In doing so, our solutions enable
e-businesses to use both the Internet and traditional business channels to build
profitable, long-lasting customer relationships.


                                       33
<PAGE>   37

  IDENTIFY AND TARGET MOST PROFITABLE CUSTOMERS


     Our Broadbase EPM solution enables e-businesses to identify their most
profitable customers and to tailor promotions and marketing campaigns, sales
efforts, product offerings and customer service based on individual buying
habits and demographics. In doing so, it allows companies to maintain and
enhance the value of their most profitable customers as well as to increase the
profitability of other customer segments.


  RESPOND RAPIDLY TO OPPORTUNITIES AND RISKS


     Our Broadbase EPM solution allows business decision makers to respond
rapidly and effectively to new opportunities and risks by providing timely
information, measuring results against industry targets and suggesting actions.
These capabilities help close the loop between a customer interaction and the
business response --that is, they help the business react to information
generated from previous customer interactions. Examples of these capabilities
include utilizing prior customer behavior to personalize web content or
identifying opportunities to sell complementary products, or "cross-sell," and
to sell higher-end products, or "up-sell." In addition, our solutions
incorporate business logic to monitor performance, identify exceptions and alert
users to key events such as ineffective promotions or service backlogs.


  ACHIEVE FAST RETURN ON INVESTMENT THROUGH RAPID IMPLEMENTATION


     Because our Broadbase EPM solution can generally be deployed in less than
30 days, businesses can rapidly begin to realize the increased revenue resulting
from personalized customer interactions, without suffering the delays associated
with the creation of in-house patchwork systems and consulting services-based
approaches. In addition, our packaged adapters for integration with Internet and
enterprise systems, and our pre-built applications, support rapid implementation
with a lower investment than applications developed in-house.


  REDUCE TOTAL COST OF OWNERSHIP


     Our Broadbase EPM solution requires fewer resources than the development
and implementation of alternatives such as in-house patchwork systems and
consulting services-based approaches. In addition, our applications are
specifically designed to be easily used by business decision makers, minimizing
training and support costs. Finally, because we offer an open platform,
businesses can easily adapt and extend our open modular solutions to meet their
changing business and technical requirements with minimal additional investment.


CASE STUDIES


     The following case studies illustrate the use of our Broadbase EPM solution
by an Internet-only company as well as a traditional "bricks and mortar"
business.


  MERCATA


     Mercata is a web-based retailer that offers an online group buying system
through which groups of buyers can exercise volume purchasing power and drive
prices lower. As its e-commerce activity increases, Mercata must analyze and
optimize content, promotions and specific group purchases, as well as improve
customer targeting.



     Mercata has licensed our Broadbase EPM solution to analyze the traffic and
buying habits of its users by integrating our product with BroadVision, which is
Mercata's e-commerce system. By analyzing their users' habits, Mercata can
discover trends and patterns, such as how often


                                       34
<PAGE>   38


consumers make offers and how much they raise their offers. In addition,
Broadbase EPM will analyze the optimal product mix, price and length of each
group purchase. Mercata can then use this information to customize and
personalize its content to attract new users and retain current ones. In
addition, our Broadbase EPM solution will enable Mercata to understand and
determine the growing purchasing leverage of Mercata's e-consumer community.
Mercata also plans to use our Broadbase EPM solution to integrate and analyze
data from Mercata's customer service call center, its enterprise resource
planning system and its e-mail management system.


  PLYMOUTH ROCK


     The Plymouth Rock Company is a property, casualty and auto insurance
company headquartered in New England. Since the state of Massachusetts sets
automobile insurance rates and prohibits insurers from denying coverage to any
driver, Plymouth faces the challenge of providing coverage to high risk drivers
while minimizing costs and claims.



     Plymouth selected Broadbase EPM to help it reduce insurance claim expenses.
By generating an enterprise-wide, customer-focused view of Plymouth's lines of
business, and by analyzing data about customers' insurance claims, Plymouth can
target low risk customers. In addition, Plymouth is incorporating sales to low
risk customers as a compensation criterion for its agents, and will automate
this process by integrating Broadbase EPM and its payroll applications.
Broadbase EPM is currently used by more than 100 employees at Plymouth and over
150 of its external insurance agents.


OUR STRATEGY


     Our objective is to be the leading provider of customer-focused e-business
solutions. To achieve this objective, we have adopted the following strategies:


  EXTEND PRODUCT LEADERSHIP IN THE E-BUSINESS ANALYTIC SOLUTIONS MARKET


     Our underlying product architecture enables us to develop new products and
enhancements rapidly. We will continue to invest significantly in research and
development to maintain and extend our product and technology leadership. We
utilize a customer-driven development cycle, focused on identifying current and
future e-business requirements, through frequent customer meetings and customer
programs. We have strategic relationships with application, technology and
system integration companies, and we work closely with these companies to
identify other opportunities to extend our product leadership.


  TARGET MULTI-CHANNEL COMPANIES AND INTERNET-ONLY BUSINESSES

     We believe that both traditional multi-channel companies and emerging,
Internet-only businesses need our integrated e-business solutions. We also
believe that both categories of businesses will continue to invest heavily in
e-business solutions, such as those offered by Broadbase, in order to
differentiate their product and service offerings, leverage the Internet as a
primary business channel and develop lasting relationships with their customers.
Accordingly, we will continue to target both multi-channel companies and
Internet-only businesses.


  LEVERAGE STRATEGIC RELATIONSHIPS



     We believe that strategic relationships with a strong network of companies
will broaden our product adoption, increase our market presence and enhance our
ability to deliver complete solutions to our customers. Our strategic
relationships with these companies provide value to both parties. For example,
our strategic relationships with application vendors enhance the value


                                       35
<PAGE>   39


of their products by allowing their customers to access, analyze and act upon
the data within these products. We plan to continue to invest in jointly
integrating, marketing and selling our solutions and services with these
companies. We plan to form new relationships with additional e-commerce software
vendors whose customers require e-business analysis. We also intend to continue
to build relationships with major systems integrators and consulting service
providers.


  EXPAND PROFESSIONAL SERVICES CAPABILITIES


     We believe that our professional services group is important to ensure our
customers' success and to drive increased sales. Our professional services group
assists businesses in developing innovative ways to implement our solution,
leading to increased adoption of our products. We plan to continue to expand our
professional services group.


  EXTEND OUR GLOBAL PRESENCE


     We believe that there will continue to be significant international
opportunities for our solutions. We currently have offices in Germany, Japan,
the Netherlands and the United Kingdom, and distributors in Japan. We plan to
continue to invest in our sales infrastructure in order to support a growing
global sales force in both the United States and in international markets,
particularly Asia-Pacific and Europe.


BROADBASE PRODUCTS AND SERVICES

  OVERVIEW OF BROADBASE EPM


     Broadbase EPM is a suite of e-business software solutions designed to
provide business decision-makers in sales, marketing, customer service and
e-commerce with analysis of customer information that is specifically designed
for their business function. This suite is built on EPM/Foundation, our software
platform that provides comprehensive analytic capabilities. We introduced
EPM/Foundation in the fourth quarter of 1997, and began offering our analytic
applications designed for specific business functions in the third quarter of
1998. In May 1999, we expanded our suite by introducing new applications
designed for e-business, as well as new versions of our existing applications.
Our Broadbase EPM applications may be licensed individually or in any
combination. A license for any one or more of our Broadbase EPM applications
also includes a license for EPM/Foundation and adapters to interface with the
customers' existing data sources. While we have derived most of our license
revenue from our EPM/Foundation product to date, we anticipate that an
increasing portion of our license revenue will be derived from our Broadbase EPM
applications.



     Each Broadbase EPM application incorporates its own data model and business
logic. The data models organize the relevant data through EPM/Foundation into
consistent formats that can support dynamic and interactive analysis. The
business logic used in each application then analyzes this data using the rules
that typically govern the decision making process within each specific business
function. It can identify risks and opportunities and suggest actions for
specific processes. For example, our E-Personalize application organizes
profiles of website visitors, analyzes the content of the web site, links
information about visitors and content and suggests types of content or products
that should be presented to the customer. Organizations can customize the data
models and business logic to support their specific and changing needs.



     EPM/Foundation is the software platform upon which each of our applications
is built. It enables the applications to extract data from multiple sources,
transform this data into a consistent format and store this data in widely used
databases such as Microsoft SQL Server and Oracle. This data can include both
real time and historic data from Internet-based systems, such as websites,
e-mail and online service, front-office applications such as sales, marketing
and customer support


                                       36
<PAGE>   40


systems, back-office applications such as finance, manufacturing and human
resources and sources of demographic data. EPM/Foundation's analytic engine
provides the capabilities that allow the Broadbase EPM applications to perform
complex function-specific analysis.



     Broadbase EPM incorporates browser-based interface that enables business
users to take advantage of all of its capabilities with minimal training. This
intuitive interface guides business users through the analysis process, while
providing sophisticated users with more extensive functionality.



     The following graphic illustrates the architecture of Broadbase EPM:

     Our Customer Service, Sales and E-Marketing applications were first
released in July 1998, and the most recent versions of each were released in May
1999. Our E-Commerce and our E-Personalize applications were first released in
May 1999. We anticipate releasing our E-Procurement application and a new
version of our E-Personalize application in the fourth quarter of 1999. Actual
features and release dates for new applications and versions could differ
materially from those projected as a result of a variety of factors, some or all
of which may be beyond our control. See "Risk Factors -- We may be unable to
attract new customers if we do not develop new products and enhancements."

STRATEGIC RELATIONSHIPS


     We establish strategic relationships to assist in the marketing, selling
and implementation of our solutions, as well as to increase the interoperability
of our solutions with our partners' complementary products. We have five types
of strategic relationships:


  SYSTEM INTEGRATORS AND CONSULTING FIRMS


     To ensure the successful implementation of our solutions, we have
established relationships with a number of leading system integrators and
consulting firms. These firms implement our products, provide related business
consulting, and often assist us in our sales process. In the United States, we
have relationships with Andersen Consulting, Cambridge Technology Partners,
Condor/DST, Ernst & Young, Renaissance Worldwide, Technology Solutions Company
and US Web/CKS. In addition, we have relationships with Internet-focused
professional services firms and regional system integrators.


  E-COMMERCE AND INTERNET SOFTWARE VENDORS

     To enhance our software, and to identify potential customers, we have
formed relationships with leading vendors of e-commerce and Internet solutions,
such as BroadVision and Kana. We jointly integrate, market and sell our
complementary solutions with BroadVision. We have also

                                       41
<PAGE>   45

been featured at BroadVision's user group meetings, internal sales meetings and
on their website. We are engaged in joint marketing and integration of our
solutions with Kana's e-mail management solution.

  FRONT AND BACK OFFICE SOFTWARE VENDORS


     To enable our solutions to integrate data from as many customer touch
points as possible, and to target the installed customer base of these
applications, we have formed relationships with leading enterprise applications
vendors. We currently have strategic relationships with Clarify, Genesys, ONYX,
Rubric, Saratoga Systems and Vantive. These software vendors highlight
Broadbase's applications in their sales cycle, at their user group meetings or
on their websites. For each of these vendors, Broadbase provides adapters that
enable integration between our complementary systems.


  TECHNOLOGY AND PLATFORM VENDORS


     To ensure that our products are based on industry standards and to take
advantage of new and emerging technologies, we have formed relationships with
key technology and platform vendors. As part of our relationship with Microsoft,
we have joined the Microsoft Data Warehouse Alliance, whose members support the
Microsoft Data Warehouse Framework. In addition, we support Windows NT, Internet
Information Server and Office 2000.


  DEMOGRAPHIC DATA PROVIDERS


     To provide more effective customer and marketing analysis, our solutions
allow businesses to integrate external demographic data with their customer
data. We have entered into joint marketing agreements with Acxiom and Dunn and
Bradstreet and are integrating our products with their products to enable our
customers to access and analyze the demographic data of these companies.



     Our strategic relationships are generally not documented in writing, or are
governed by agreements that can be terminated by either party with little or no
notice. These agreements generally provide for the parties to cooperate to make
joint press releases, do joint marketing and where appropriate to integrate
their products or make them compatible with each other. These agreements may
also specify that payments are to be made by us to these companies for providing
us with qualifying customer leads. The generation of leads to date by these
companies has not generally satisfied the specified criteria and therefore
payments for leads have been immaterial in amount.


SALES AND MARKETING


     We sell our software through both our direct sales force and indirect sales
channels. As of June 30, 1999, our sales group consisted of 40 employees, in ten
locations -- six offices in the United States and four offices internationally,
which are located in Germany, Japan, the Netherlands and the United Kingdom. Our
direct sales force consists of sales representatives as well as sales personnel
who provide pre-sales technical support and other support personnel. We plan to
expand our direct sales force significantly. Our corporate sales organization is
responsible for collecting inbound leads, performing initial qualification and
introducing each prospective customer to a direct sales representative. We sell
to companies at the departmental level, targeting directors and executives in
e-commerce, sales, marketing, customer service and information technology.


                                       42
<PAGE>   46


     Our indirect sales channel includes companies such as Baan, Datamedica and
Indus, which sell our products as part of an integrated solution with their own
offerings. Indus selected EPM/Foundation as the platform on which to build its
Indus Knowledge Warehouse solution, which it licenses to its customers in the
utility and energy industries. Indus represented 18.4% of our revenue in 1998
and 11.0% of our revenue in the first six months of 1999. Baan selected
EPM/Foundation as the platform on which to build its Enterprise Decision Manager
decision support suite. We also have distributors in Japan, which include Beacon
Information Technology, Compaq Computer K.K., Oki Electric Industry, Sharp
System Products and Teijin Systems Technology.



     Our distribution relationships are generally governed by agreements that
can be terminated by either party with little or no prior notice. These
agreements generally grant nonexclusive licenses to distribute our products, are
not subject to minimum purchase requirements and provide for certain discounts
on the purchase prices of our products. We entered into our distribution
agreement with Indus, which contains similar provisions, on June 2, 1998. This
agreement is effective until June 30, 2001 and will automatically renew for
additional one year terms unless it is terminated earlier by either party with
30 days written notice prior to the date of the automatic renewal.



     We focus our marketing efforts on sales lead generation, sales support,
creating market awareness of our solutions and establishing strategic
relationships. Our marketing activities include direct mail and e-mail
campaigns, press relations and industry analyst briefings, speaking engagements,
attendance at partners' user group meetings and industry trade shows, and
participation in sales and marketing programs of companies with whom we have
strategic relationships.



INTERNATIONAL OPERATIONS



     International sales represented approximately 5.1% of our total net revenue
for 1998 and 23.6% of our total net revenue in the first six months of 1999, all
of which consisted of sales of EPM/Foundation to customers in Japan and Germany.
We currently conduct our international sales primarily through direct sales
offices in Germany, the Netherlands and the United Kingdom, and through
distributors in Japan. We believe that there will continue to be significant
international opportunities for our integrated e-business solutions. As a
result, we intend to expand our international operations and to continue to
invest in our sales infrastructure in order to support a growing global sales
force in international markets, particularly Asia-Pacific and Europe.



     The expansion of our existing international operations and entry into
additional international markets will require significant management attention
and financial resources. In particular, we must develop local versions of our
products for foreign markets and must recruit and train an international staff.
Currently, we have only limited experience in localizing our products and in
marketing, selling and supporting our products and services overseas.


RESEARCH AND DEVELOPMENT

     Our research and development organization is comprised of separate groups
responsible for core product development, application development and product
strategy and management. The core product development group is responsible for
ongoing development of EPM/Foundation. Our application development group is
responsible for developing new Broadbase EPM applications and enhancing existing
applications. Our product strategy and management group is responsible for
prioritizing customer requirements and defining the resources and timelines
necessary to deliver products. Our current research and development efforts are
focused on the

                                       43
<PAGE>   47

development of additional applications and other enhancements that extend the
e-business functionality of our solutions.


     Our research and development expenditures were $928,000 in the period from
November 28, 1995 (inception) to December 31, 1996, $2.0 million in 1997, $3.7
million in 1998 and $2.8 million in the six months ended June 30, 1999. We
expect that we will continue to commit significant resources to research and
development in the future. The market for our products and services is
characterized by rapid technological change, frequent new product introductions
and enhancements, evolving industry standards, and rapidly changing customer
requirements. Our future success will depend in part on our ability to
anticipate changes, enhance our current products, develop and introduce new
products that keep pace with technological advancements and address the
increasingly sophisticated needs of our customers. See "Risk Factors -- We may
be unable to attract new customers if we do not develop new products and
enhancements."


COMPETITION

     Our competitors vary in company size, and in the scope and breadth of their
products and services. We have three primary sources of competition:


     - providers of consulting services-based analysis solutions, such as
       E.piphany;



     - vendors of point technologies that provide website analysis such as
       Accrue, Andromedia and Net Perceptions; and



     - in-house development efforts by potential customers using traditional and
       generic decision support tools.



     In addition, we face potential competition from vendors of other enterprise
applications as they expand the functionality of their product offerings. These
vendors may include Oracle, SAP, Siebel, other vendors of software designed for
decision support or management of customer relationships or of organizations'
operational information. They also may include vendors of database applications.


     Principal competitive factors include:

     - quality, breadth and depth of application offerings;

     - product robustness and extensibility;

     - openness of technology architecture;

     - ease of deployment and maintenance;

     - quality of services and customer support; and

     - price.


     Although we believe that our solutions compete favorably with respect to
these factors, our market is new and rapidly evolving. We may not be able to
maintain our competitive position against current and potential competitors. See
"Risk Factors -- We face intense competition which could make it difficult to
acquire and retain customers."



     We face the same sources of competition both domestically and
internationally. However, it faces additional challenges in selling its products
and services internationally. See "-- International Operations."


                                       44
<PAGE>   48

INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS


     Our success and ability to compete are dependent on our ability to develop
and maintain the proprietary aspects of our technology. We rely on a combination
of trademark, trade secret and copyright law and contractual restrictions to
protect the proprietary aspects of our technology. We have no patents or pending
patent applications. We seek to protect our source code for our software,
documentation and other written materials under trade secret and copyright laws.
We license our software under signed license agreements, which impose
restrictions on the licensee's ability to utilize the software. Finally, we seek
to avoid disclosure of our intellectual property by requiring employees and
consultants with access to our proprietary information to execute
confidentiality agreements with us and by restricting access to our source code.
Despite our efforts to protect our proprietary rights, unauthorized parties may
attempt to copy aspects of our products or to obtain and use information that we
regard as proprietary. Our success and ability to compete are also dependent on
our ability to operate without infringing upon the proprietary rights of others.
See "Risk Factors -- We depend on our intellectual property, and litigation
regarding our intellectual property could harm our business."



     We currently rely on software that we have licensed from a number of
suppliers. These licenses may not continue to be available to us on commercially
reasonable terms or at all. If these licenses cease to be available, we believe
we could license equivalent software on commercially reasonable terms. In the
future, we expect to license other third party technologies to enhance our
products, meet evolving customer needs or adapt to changing technology
standards. Failure to license, or the loss of any license of necessary
technologies could result in delays or reductions of shipments of our products
until equivalent software is identified, licensed and integrated or developed by
us. See "Risk Factors -- Failure to license necessary third party software
incorporated in our products may cause delays or reductions in our sales."


EMPLOYEES


     As of June 30, 1999, we had 105 full-time employees, including 40 in sales
and four in marketing, 33 in research and development, 14 in administrative,
nine in professional services and five in customer support. Our future success
will depend in part on our ability to attract, train, retain, integrate and
motivate highly qualified sales, technical and management personnel, for whom
competition is intense. From time to time we also employ independent contractors
to support our services, product development, sales and marketing departments.
Our employees are not represented by any collective bargaining unit, and we have
never experienced a work stoppage. We believe our relations with our employees
are good.


FACILITIES

     Our principal office occupies approximately 21,000 square feet in Menlo
Park, California under a lease that expires on July 31, 2002. In addition, we
also lease sales and support offices in the United States in the metropolitan
areas of Atlanta, Chicago, Dallas, New York and Oakland, and internationally in
the metropolitan areas of Amsterdam, Frankfurt, London and Tokyo.


LEGAL PROCEEDINGS



     On July 21, 1999, Timeline, Inc. filed a complaint against us in the United
States District Court for the Western District of Washington, alleging
infringement by us of U.S. Patent No. 5,802,511 held by Timeline. Timeline
alleges that we directly and indirectly infringe its patent claims by making,
using, selling and offering to sell software products, both alone and in
combination with third party software products, and further alleges that we
induce infringement

                                       45
<PAGE>   49


of the Timeline patent claims. Timeline has requested permanent injunctions
prohibiting us from directly or indirectly infringing the Timeline patent, and
seeks damages, exemplary damages, costs and attorneys' fees. Timeline has
further disclosed to us patent claims of a pending related patent application
that Timeline expects to be issued and to be added to the present case. Based on
our investigation of this matter to date, we believe that we do not infringe any
valid claims of the Timeline patent or of the pending patent application, and
that we have other meritorious defenses to all claims made by Timeline.
Accordingly, we intend to defend this suit vigorously. Nevertheless, it is
possible that we could be found liable for infringing the Timeline patent. See
"Risk Factors -- We depend on our intellectual property, and litigation
regarding our intellectual property could harm our business."

     Our Board of Directors is currently comprised of four directors. Upon the
closing of the offering, any existing contractual rights of stockholders with
respect to Board representation will terminate and no stockholders will have any
special rights with respect to Board representation. Directors are elected by
the stockholders at each annual meeting of stockholders and serve for one year
or until their successors are duly elected and qualified. However, our
certificate of incorporation and bylaws provide, following the offering, that
our Board of Directors will be divided into three classes as nearly equal in
size as possible with staggered three-year terms. The term of office of our
Class I directors will expire at the annual meeting of stockholders to be held
in 2000; the term of office of our Class II directors will expire at the annual
meeting of stockholders to be held in 2001; and the term of office of our Class
III directors will expire at the annual meeting of stockholders to be held in
2002. At each annual meeting of stockholders, beginning with the 2000 annual
meeting, the successors to the directors whose terms will then expire will be
elected to serve from the time of their election and qualification until the
third annual meeting following their election or until their successors have
been duly elected and qualified, or until their earlier resignation or removal.
Mr. Harvey has been designated as a Class I director; Ms. Schoendorf has been
designated as a Class II director; and Mr. Kremer and Mr. Levy have been
designated as Class III directors. The classification of our Board of Directors
could have the effect of making it more difficult for a third party to acquire,
or of discouraging a third party from acquiring, control of Broadbase.


BOARD COMMITTEES

     Our Board of Directors has a compensation committee and an audit committee.

     Compensation committee. The current members of our compensation committee
are Mr. Harvey and Ms. Schoendorf. The compensation committee reviews and makes
recommen-

                                       48
<PAGE>   52


dations to our Board of Directors concerning salaries and incentive compensation
for our officers and employees. The compensation committee also administers our
1996 Equity Incentive Plan and will administer our 1999 Equity Incentive Plan
and 1999 Employee Stock Purchase Plan.



     Audit committee. The current members of our audit committee are Mr. Harvey
and Ms. Schoendorf. Our audit committee reviews and monitors our financial
statements and accounting practices, makes recommendations to our Board of
Directors regarding the selection of independent auditors and reviews the
results and scope of the audit and other services provided by our independent
auditors.


COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION


     None of the members of the compensation committee has at any time since our
formation been an officer or employee of Broadbase. No executive officer of
Broadbase currently serves, or in the past has served, as a member of the Board
of Directors or compensation committee of any entity that has one or more
executive officers serving on our Board of Directors or compensation committee.


DIRECTOR COMPENSATION

     Our directors do not receive cash compensation for their services as
directors but are reimbursed for their reasonable and necessary expenses in
attending board and committee meetings.


     Each non-employee director who is or becomes a member of our Board of
Directors on or after the date of this offering and who has not previously
received shares or options in Broadbase will be granted an option to purchase
10,000 shares of our common stock under the 1999 Equity Incentive Plan.
Immediately following each annual meeting of our stockholders, each non-employee
director will automatically be granted an additional option to purchase 10,000
shares under that plan if the director has served continuously as a member of
our Board of Directors since the date of the director's initial grant. Each
option will have an exercise price equal to the fair market value of our common
stock on the date of grant and will have a ten-year term. Each of these options
will be immediately exercisable and fully vested.



     In May 1999, we granted to Paul Levy, one of our directors, an option to
purchase 96,750 shares of common stock at an exercise price of $0.73 per share.
Mr. Levy exercised this option in full in May 1999. This option vests as to
12,094 shares in November 1999 and vests as to 1/48 of the original number of
shares subject to the option each month thereafter. Broadbase has the right to
repurchase the unvested shares of this option if Mr. Levy ceases to provide
services as a director of Broadbase.

     Brian Kelly was hired as Executive Vice President of Applications and
Engineering in December 1998 and is compensated at an annual rate of $150,000
with bonuses of up to $30,000. Thomas Doyle was hired as Executive Vice
President of Sales in May 1999 and is compensated at an annual rate of $225,000
with a targeted commission of $100,000. Mr. Doyle's commission is dependent upon
his level of performance. If Mr. Doyle achieves 100% of the annual sales target
established by Broadbase, he would earn $100,000 in commission income. If Mr.
Doyle exceeds the sales target, he would earn more than $100,000 in commission
income. If Mr. Doyle fails to meet the sales target, his commission income would
be reduced to the percentage of $100,000 that actual sales represent of the
sales target. By way of example, if Mr. Doyle achieves 80% of the sales target,
he would earn $80,000 in commission income. Anil Gupta was hired as Vice
President of Marketing in August 1999 and is compensated at an annual rate of
$150,000 with bonuses of up to $40,000 per year.


OPTION GRANTS IN 1998

     The following table shows information about each stock option grant during
1998 to the officers named in the Summary Compensation Table above.


     All options included in the following table are immediately exercisable and
are incentive stock options. We have a right to repurchase the shares issued on
exercise of these options upon termination of the optionee's employment. This
right lapses over a four-year period and will lapse as to 50% of the 173,000
shares upon a change of control of Broadbase. All options were granted at an
exercise price equal to the fair market value of our common stock, as determined
by our Board of Directors on the date of grant.

AGGREGATED OPTION EXERCISES IN 1998 AND YEAR-END OPTION VALUES

     The following table provides information concerning stock option exercises
by each of the executive officers named in the Summary Compensation Table above
that exercised options during the fiscal year ended December 31, 1998 and
information concerning unexercised options held by these officers at the end of

options upon termination of the optionee's employment. Our right to repurchase
the shares lapses over a four-year period from the date of grant. In the
following table, the heading "exercisable" refers to shares that were
exercisable although our right to repurchase unvested shares had not lapsed.

(1) We entered into a Separation Agreement, effective April 14, 1999, with our
    former Vice President of Sales, Bruce Armstrong. The Separation Agreement
    provides for termination of Mr. Armstrong's employment as of June 30, 1999,
    payment of salary and benefits by the Company to Mr. Armstrong through June
    30, 1999, the continuation of vesting of Mr. Armstrong's options through
    June 30, 1999 and the repurchase of all 119,581 unvested shares held by Mr.
    Armstrong as of June 30, 1999.


EMPLOYEE BENEFIT PLANS

  1996 EQUITY INCENTIVE PLAN


     We adopted our 1996 Equity Incentive Plan in April 1996. As of June 30,
1999, there were outstanding options to purchase a total of 2,013,249 shares of
common stock under this plan, and 572,443 shares remained available for future
grants of options under this plan. This plan will terminate immediately prior to
this offering, and no further options will be granted under this plan after this
offering. However, the termination of this plan will not affect any outstanding
options, which will remain outstanding until they are exercised or until they
terminate or expire.


  1999 EQUITY INCENTIVE PLAN

     We intend to adopt the 1999 Equity Incentive Plan and intend to reserve
3,500,000 shares of common stock for issuance under this plan. The number of
shares reserved for issuance under this plan will be increased to include any
shares reserved under our 1996 Equity Incentive Plan not issued or subject to
outstanding grants on the date of this prospectus and any shares issued under
our 1996 Equity Incentive Plan that are forfeited or repurchased by us at the
original purchase price or that are issuable upon exercise of options granted
under our 1996 Equity Incentive Plan that expire or become unexercisable for any
reason without having been exercised in full. Thereafter the number of shares
reserved under this plan will be increased

                                       51
<PAGE>   55


automatically on December 31, 1999 and each anniversary thereafter, by an amount
equal to 5% of the total outstanding shares as of the immediately preceding
December 31st. Our 1999 Equity Incentive Plan will become effective on the date
of this prospectus and will serve as the successor to our 1996 Equity Incentive
Plan. The following shares will be available for grant and issuance under our
1999 Equity Incentive Plan:


     - shares subject to issuance upon exercise of an option granted under our
       1999 Equity Incentive Plan that cease to be subject to that option for
       any reason other than exercise of the option;

     - shares issued pursuant to the exercise of an option granted under our
       1999 Equity Incentive Plan that are subsequently forfeited or repurchased
       by us at the original purchase price;

     - shares subject to awards granted pursuant to restricted stock purchase
       agreements under our 1999 Equity Incentive Plan that are subsequently
       forfeited or repurchased by us at the original issue price; and


     - shares subject to stock bonuses granted under our 1999 Equity Incentive
       Plan that terminate without shares being issued.


     Our 1999 Equity Incentive Plan will terminate in 2009, unless sooner
terminated in accordance with the terms of the plan.


     Our 1999 Equity Incentive Plan authorizes the award of options, restricted
stock awards and stock bonuses. Our non-employee directors are entitled to
receive automatic annual grants of fully vested options to purchase 10,000
shares of our common stock, as described under "Management -- Director
Compensation." Additionally, our non-employee directors are eligible to receive
discretionary awards under our 1999 Equity Incentive Plan. Our 1999 Equity
Incentive Plan is administered by the compensation committee of our Board of
Directors, which currently consists of Mr. Harvey and Ms. Schoendorf, both of
whom are "non-employee directors" under applicable federal securities laws and
"outside directors" as defined under applicable federal tax laws. The committee
has the authority to construe and interpret this plan and any agreement made
thereunder, grant awards and make all other determinations necessary or
advisable for the administration of this plan.



     Our 1999 Equity Incentive Plan provides for the grant of both incentive
stock options that qualify under Section 422 of the Internal Revenue Code and
nonqualified stock options. Incentive stock options may be granted only to
employees. Nonqualified stock options, and all other awards other than incentive
stock options, may be granted to employees, officers, directors, consultants,
independent contractors and advisors of Broadbase or any parent or subsidiary of
Broadbase. However, consultants, independent contractors and advisors are only
eligible to receive awards if they render bona fide services not in connection
with the offer and sale of securities in a capital-raising transaction. The
exercise price of incentive stock options must be at least equal to the fair
market value of our common stock on the date of grant. The exercise price of
incentive stock options granted to 10% stockholders must be at least equal to
110% of that value. The exercise price of nonqualified stock options must be at
least equal to 85% of the fair market value of the our common stock on the date
of grant.



     The maximum term of options granted under our 1999 Equity Incentive Plan is
ten years. Awards other than nonqualified stock options granted under this plan
may not be transferred in any manner other than by will or by the laws of
descent and distribution and may be exercised during the lifetime of the
optionee only by the optionee. The plan allows exceptions to this restriction
with respect to awards that are nonqualified stock options. Options granted
under our 1999 Equity Incentive Plan generally expire three months after the
termination of the


                                       52
<PAGE>   56

optionee's service to Broadbase or a parent or subsidiary of Broadbase. In the
event of a "change in control" transaction, outstanding awards may be assumed or
substituted by the successor corporation. The compensation committee may also
accelerate the vesting of awards upon a change of control transaction.

  1999 EMPLOYEE STOCK PURCHASE PLAN

     We intend to adopt the 1999 Employee Stock Purchase Plan prior to
completion of this offering, and to reserve a total of 500,000 shares of common
stock for issuance under this plan. On each January 1, the aggregate number of
shares reserved for issuance under our 1999 Employee Stock Purchase Plan will be
increased automatically by a number of shares equal to 1% of our outstanding
shares on the preceding December 31. Our compensation committee will administer
our 1999 Employee Stock Purchase Plan. The plan will become effective on the
first day on which price quotations are available for our common stock on the
Nasdaq National Market.


     Employees generally will be eligible to participate in our 1999 Employee
Stock Purchase Plan if they are employed 10 days before the beginning of the
applicable offering period and they are customarily employed by Broadbase or its
parent or any subsidiaries that Broadbase designates for more than 20 hours per
week and more than five months in a calendar year. Employees are not eligible to
participate in our 1999 Employee Stock Purchase Plan if they are 5%
stockholders, or would become 5% stockholders as a result of their participation
in this plan.



     Under our 1999 Employee Stock Purchase Plan, eligible employees will be
able to acquire shares of our common stock through payroll deductions. Eligible
employees may select a rate of payroll deduction between 2% and 10% of their
cash compensation and are subject to certain maximum purchase limitations.
Participation in this plan will end automatically upon termination of employment
for any reason.



     Each offering period under our 1999 Employee Stock Purchase Plan will be
for two years and will consist of four six-month purchase periods. The first
offering period is expected to begin on the first business day on which price
quotations for Broadbase's common stock are available on the Nasdaq National
Market. The first purchase period may be more or less than six months long.
Offering periods and purchase periods thereafter will begin on February 1 and
August 1.


     The purchase price for common stock purchased under our 1999 Employee Stock
Purchase Plan will be 85% of the lesser of the fair market value of our common
stock on the first day of the applicable offering period or the last day of each
purchase period. The compensation committee will have the power to change the
duration of offering periods. Our 1999 Employee Stock Purchase Plan is intended
to qualify as an "employee stock purchase plan" under Section 423 of the
Internal Revenue Code. The plan will terminate in 2009, unless it is terminated
earlier pursuant to its terms.

  401(K) PLAN

     We sponsor a defined contribution plan intended to qualify under Section
401(k) of the Internal Revenue Code. All employees are generally eligible to
participate and may enter the 401(k) plan as of the first day of each month.
Participants may make pre-tax contributions to the plan of up to 20% of their
eligible pay, subject to a statutorily prescribed annual limit. Participants are
fully vested in their contributions and the investment earnings. Individual
participants may direct the trustee to invest their accounts in authorized
investment alternatives.

EMPLOYMENT AGREEMENTS


     In August 1999, we executed an offer letter to Anil Gupta, our Vice
President of Marketing. This offer letter establishes Mr. Gupta's annual base
salary at $150,000. In addition, the offer letter provides for bonuses of up to
$40,000 per year. Under the offer letter, Mr. Gupta was granted an option to
purchase 170,000 shares of common stock at an exercise price of $4.56 per share.
This option vests as to 12.5% of the shares on February 4, 2000 and 2.083% of
the shares each month thereafter. In the event of a change in control of
Broadbase and termination of Mr. Gupta's position, 50% of the then unvested
shares issuable upon exercise of this option will immediately vest. Broadbase
will provide Mr. Gupta the health, holiday, vacation and other benefits
available to all its employees. Mr. Gupta's employment is considered an
"at-will" agreement. Mr. Gupta or Broadbase may terminate the employment
relationship at any time for any reason.



     In April 1999, we executed an offer letter to Thomas Doyle, our Executive
Vice President of Sales. This offer letter establishes Mr. Doyle's annual base
salary at $225,000 and a commission of $100,000, which can increase or decrease
if sales are above or below an established sales target. The letter also
provides for a sign-on bonus of $250,000 to be paid on his first day of
employment and an additional bonus of $250,000 payable on July 1, 1999. Each
bonus is subject to repayment if he voluntarily terminates his employment less
than 18 months after the payment of that bonus and describes his eligibility for
benefits. Under this offer letter, Mr. Doyle was granted options to purchase
240,000 shares of common stock at an exercise price of $0.73 per share, vesting
over a four year period. An option to purchase 60,000 of these shares will
become exercisable only if a specified sales target is achieved. In the event of
a change of control of Broadbase and Mr. Doyle's involuntary termination, 50% of
his unvested shares will immediately vest. Broadbase will provide Mr. Doyle the
health, holiday, vacation and other benefits available to all its employees. Mr.
Doyle's employment is considered an "at-will" agreement. Mr. Doyle or Broadbase
may terminate the employment relationship at any time for any reason.



     In November 1998, we executed an offer letter to Brian Kelly, our Executive
Vice President of Applications and Engineering. This offer letter establishes
Mr. Kelly's annual base salary at $150,000. In addition, the offer letter
provides for bonuses of up to $30,000 a year. Under this offer letter, Mr. Kelly
was granted an option to purchase 135,000 shares of common stock at an exercise
price of $0.73 per share. This option was immediately exercisable in full and
Broadbase has a right to repurchase the shares issued upon exercise of this
option upon termination of Mr. Kelly's employment. This repurchase right lapses
over a four-year period. In addition, the agreement provided for the grant of an
option to purchase an additional 20,000 shares to Mr. Kelly under certain
circumstances. On May 27, 1999, Mr. Kelly was granted options to purchase
115,000 shares of our common stock at an exercise price of $0.73 per share. Of
these options, 20,000 shares vest as to 12.5% of the shares on June 1, 1999 and
2.083% each month thereafter and 95,000 shares vest as to 12.5% of the shares on
June 1, 1999 and 4.16% each month thereafter. In the event of a change of
control, 50% of the shares issued upon exercise of the option to purchase 20,000
shares will immediately vest. Broadbase will provide Mr. Kelly the health,
holiday, vacation and other benefits available to all its employees. Mr. Kelly's
employment is considered an "at-will" agreement. Mr. Kelly or Broadbase may
terminate the employment relationship at any time for any reason.



     In January 1998, we executed an offer letter to Chuck Bay, our Chief
Financial Officer, General Counsel, Executive Vice President of Business
Development and Corporate Secretary. This offer letter establishes Mr. Bay's
annual base salary at $150,000. In addition, the offer letter provided for
bonuses of up to $40,000 a year. Under this offer letter, Mr. Bay was granted an
option to purchase 173,000 shares of common stock at an exercise price of $0.25
per share. This option was immediately exercisable in full, and Broadbase has a
right to


                                       54
<PAGE>   58


repurchase the shares issued upon exercise of this option upon termination of
Mr. Bay's employment. This repurchase right lapses over a four-year period. In
the event of a change of control, 50% of the shares issued upon exercise of this
option will immediately vest. Broadbase will provide Mr. Bay the health,
holiday, vacation, 401(k) and other benefits available to all its employees. Mr.
Bay's employment is considered an "at-will" agreement. Mr. Bay or Broadbase may
terminate the employment relationship at any time for any reason.


INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY

     Our certificate of incorporation limits the liability of our directors to
the maximum extent permitted by Delaware law. Delaware law provides that a
director of a corporation will not be personally liable for monetary damages for
breach of fiduciary duty as a director, except for liability:

     - for any breach of the director's duty of loyalty to Broadbase or our
       stockholders;

     - for acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;

     - under Delaware law regarding unlawful dividends and stock purchases; or

     - for any transaction from which the director derived an improper personal
       benefit.

     As permitted by Delaware law, our bylaws provide that:

     - we must indemnify our directors and executive officers to the fullest
       extent permitted by Delaware law, provided that each indemnified officer
       and director acted in good faith and in a manner that the officer or
       director reasonably believed to be in or not opposed to Broadbase's best
       interests;

     - we may indemnify our other employees and agents; and

     - we must advance expenses, as incurred, to our directors and executive
       officers in connection with a legal proceeding to the fullest extent
       permitted by Delaware law, subject to very limited exceptions.


     In addition to the indemnification required in our certificate of
incorporation and bylaws, we intend to enter into indemnification agreements
with each of our current directors and executive officers, prior to the
completion of this offering. We also intend to obtain directors' and officers'
insurance to cover our directors, officers and some of our employees for certain
liabilities. We believe that these indemnification provisions and agreements and
this insurance are necessary to attract and retain qualified directors and
officers.


     The limitation of liability and indemnification provisions in our
certificate of incorporation and bylaws may discourage stockholders from
bringing a lawsuit against directors for breach of their fiduciary duty. They
may also reduce the likelihood of derivative litigation against directors and
officers, even though an action, if successful, might benefit us and other
stockholders. Furthermore, a stockholder's investment may be adversely affected
to the extent we pay the costs of settlement and damage awards against directors
and officers as required by these indemnification provisions.

     Presently, there is no pending litigation or proceeding involving any of
our directors, officers or employees for which indemnification is sought, nor
are we aware of any threatened litigation that may result in claims for
indemnification.

                              CERTAIN TRANSACTIONS


     Other than the transactions described in "Management" and the transactions
described below, since the incorporation of Broadbase on November 28, 1995,
there has not been nor is there currently proposed any transaction or series of
similar transactions to which we were or will be a party:


     - in which the amount involved exceeded or will exceed $60,000; and

     - in which any director, executive officer, holder of more than 5% of our
       common stock or any member of his or her immediate family had or will
       have a direct or indirect material interest.


TRANSACTIONS WITH PROMOTER


     On November 30, 1995, in connection with the formation and initial
financing of Broadbase, Mark Kremer purchased 1,282,500 shares of our common
stock for an aggregate purchase price of $2,565. Mr. Kremer is our President,
Chief Executive Officer and Chairman of the Board of Directors, and may be
considered to be a promoter of Broadbase. Broadbase retained the right to
repurchase 1,154,250 of these shares, at his initial purchase price, if Mr.
Kremer ceased to be employed by Broadbase. This repurchase right lapses at a
rate of 24,046 shares per month.

DEBENTURE FINANCINGS IN WHICH 5% STOCKHOLDERS PARTICIPATED


     In December 1998 and April 1999, we sold debentures in the aggregate
principal amount of $9,525,000, which principal amount is convertible into a
total of 1,313,793 shares of Series D preferred stock at a conversion price of
$7.25 per share. Unless earlier converted by their terms into stock of
Broadbase, $8,250,000 in principal amount of the debentures must be repaid on
December 9, 2003, and $1,275,000 in principal amount must be repaid on April 15,
2004. Charter Growth Capital and certain of its affiliated funds purchased
$8,000,000 of the debentures. These funds would hold more than 5% of our
outstanding stock if these debentures were converted into stock. These
debentures are convertible into 1,103,448 shares of Series D preferred stock.
Upon the closing of this offering, the debentures will be converted into an
equal number of shares of common stock. None of our executive officers,
directors or other holders of more than 5% of our outstanding common stock
purchased any of the debentures.

                          DESCRIPTION OF CAPITAL STOCK


     Immediately following the closing of this offering, the authorized capital
stock of Broadbase will consist of 90,000,000 shares of common stock, $0.001 par
value per share, and 15,154,046 shares of preferred stock, $0.001 par value per
share, of which 5,000,000 shares will be available for future issuance. As of
June 30, 1999, and assuming the conversion of all outstanding preferred stock
and convertible debentures into common stock upon the closing of this offering,
there were outstanding 13,203,690 shares of common stock held of record by
approximately 150 stockholders, and options to purchase 2,013,249 shares of
common stock and warrants to purchase 36,764 shares of common stock.


     Before the closing of this offering, Broadbase will reincorporate in the
State of Delaware. Following the closing of this offering, we intend to amend
and restate our certificate of incorporation to reflect the conversion of our
preferred stock to common stock.

COMMON STOCK


     Dividend rights. Subject to preferences that may apply to shares of
preferred stock outstanding at the time, the holders of outstanding shares of
common stock are entitled to receive dividends out of assets legally available
at the times and in the amounts as our Board of Directors may from time to time
determine.


     Voting rights. Each common stockholder is entitled to one vote for each
share of common stock held on all matters submitted to a vote of stockholders.
Cumulative voting for the election of directors is not provided for in our
certificate of incorporation, which means that the holders of a majority of the
shares voted can elect all of the directors then standing for election.

     No preemptive or similar rights. The common stock is not entitled to
preemptive rights and is not subject to conversion or redemption.

     Right to receive liquidation distributions. Upon a liquidation, dissolution
or winding-up of Broadbase, the holders of common stock are entitled to share
ratably with holders of any participating preferred stock in all assets
remaining after payment of all liabilities and the liquidation preferences of
any outstanding preferred stock. Each outstanding share of common stock is, and
all shares of common stock to be outstanding upon completion of this offering
will be, fully paid and nonassessable.

PREFERRED STOCK


     Upon the closing of this offering, each outstanding share of preferred
stock will be converted into shares of common stock. See Note 5 of Notes to
Consolidated Financial Statements for a description of this preferred stock.



     Following the offering, Broadbase will be authorized, subject to the limits
imposed by Delaware law, to issue preferred stock in one or more series, to
establish from time to time the number of shares to be included in each series
and to fix the rights, preferences and privileges of the shares of each wholly
unissued series and any of its qualifications, limitations or restrictions. Our
Board of Directors can also increase or decrease the number of shares of any
series, but not below the number of shares of any series then outstanding,
without any further vote or action by the stockholders.



     Our Board of Directors may authorize the issuance of preferred stock with
voting or conversion rights that could adversely affect the voting power or
other rights of the holders of the common stock. The issuance of preferred
stock, while providing flexibility in connection with possible acquisitions and
other corporate purposes, could, among other things, have the effect of
delaying, deferring or preventing a change in control of Broadbase and may
adversely affect the market price of the common stock and the voting and other
rights of the holders of


                                       60
<PAGE>   64

common stock. We have no current plan to issue any shares of preferred stock
after the offering.

REGISTRATION RIGHTS


     The holders of approximately 9,961,882 shares of common stock have the
right to require us to register their shares with the Securities and Exchange
Commission so that those shares may be publicly resold or to include their
shares in any registration statement we file.


  DEMAND REGISTRATION RIGHTS


     At any time more than six months after the closing of this offering, the
holders of at least 30% of the shares having registration rights have the right
to demand that we file a registration statement so that they can publicly sell
their shares, so long as the value of the securities to be sold in that
registration exceeds $7,500,000. In addition, if we are eligible to file a
registration statement on Form S-3, the holders of at least 20% of the shares
having registration rights have the right to demand that we file a registration
statement on Form S-3, so long as the amount of securities to be sold in that
registration exceeds $500,000.


  PIGGYBACK REGISTRATION RIGHTS


     If we register any securities for public sale, these stockholders will have
the right to include their shares in the registration statement. The
underwriters of any underwritten offering will have the right to limit the
number of shares to be included in that registration statement.


  EXPENSES OF REGISTRATION

     We generally will pay all of the expenses relating to any demand or
piggyback registration.

  EXPIRATION OF REGISTRATION RIGHTS


     The registration rights described above will expire five years after this
closing of this offering. The registration rights will terminate earlier with
respect to a particular stockholder if that holder owns less than 1% of our
outstanding securities, that holder can resell all of its securities in a
three-month period under Rule 144 of the Securities Act and we are subject to
the reporting requirements of the Securities Exchange Act of 1934.


ANTI-TAKEOVER PROVISIONS


     Certain provisions of Delaware law, our certificate of incorporation and
bylaws described below may have the effect of delaying, deferring or
discouraging another person from acquiring control of our company.


  DELAWARE LAW

     We will be subject to the provisions of Section 203 of the Delaware General
Corporation Law regulating corporate takeovers. This section prevents certain
Delaware corporations from engaging, under limited circumstances, in a "business
combination," which includes a merger or

                                       61
<PAGE>   65


sale of more than 10% of the corporation's assets, with any "interested
stockholder," or a stockholder who owns 15% or more of the corporation's
outstanding voting stock, as well as affiliates and associates of such
stockholder, for three years following the date that stockholder becomes an
"interested stockholder" unless:


     - the transaction is approved by the board prior to the date the
       "interested stockholder" attained that status;

     - upon the closing of the transaction that resulted in the stockholder's
       becoming an "interested stockholder," the "interested stockholder" owned
       at least 85% of the voting stock of the corporation outstanding at the
       time the transaction commenced; or

     - on or subsequent to such date the "business combination" is approved by
       the board and authorized at an annual or special meeting of stockholders
       by at least two-thirds of the outstanding voting stock that is not owned
       by the "interested stockholder."

     This provision could prohibit or delay mergers or other takeover or
change-in-control attempts and, accordingly, may discourage attempts to acquire
us.

  CHARTER AND BYLAW PROVISIONS


     Our certificate of incorporation and bylaws provide for the division of our
Board of Directors into three classes as nearly equal in size as reasonably
possible with staggered three-year terms. Our stockholders are unable to fill
any vacancy on our Board of Directors. Any action required or permitted to be
taken by our stockholders at an annual meeting or a special meeting of the
stockholders may only be taken if it is properly brought before that meeting and
may not be taken by written consent. Our stockholders are limited in their
ability to remove any director or the entire Board of Directors without cause.
Our bylaws provide that special meetings of the stockholders may be called at
any time by the Board of Directors, and must be called upon the request of the
chairman of the Board of Directors, the chief executive officer, the president,
stockholders that are entitled to cast not less than a majority of the total
number of votes entitled to be cast by all stockholders at that special meeting,
or by a majority of the members of the Board of Directors. These provisions of
our certificate of incorporation and bylaws are intended to enhance the
likelihood of continuity and stability in the composition of the Board of
Directors and to discourage transactions that may involve an actual or
threatened change of control of Broadbase. These provisions are designed to
reduce the vulnerability of Broadbase to an unsolicited acquisition proposal
and, accordingly, could discourage potential acquisition proposals and could
delay or prevent a change in control of Broadbase. These provisions are also
intended to discourage tactics that may be used in proxy fights but could have
the effect of discouraging others from making tender offers for our shares and,
consequently, might also inhibit fluctuations in the market price of our shares
that could result from actual or rumored takeover attempts. These changes may
also have the effect of preventing changes in our management.


TRANSFER AGENT AND REGISTRAR


     The transfer agent and registrar for our common stock is U.S. Stock
Transfer Corporation. The address of our transfer agent and registrar is 1745
Gardena Avenue, Glendale, California 91204-2991, and its telephone number at
this location is (818) 502-1404.


LISTING

     We have applied to list our common stock on the Nasdaq National Market
under the trading symbol "BBSW."

                        SHARES ELIGIBLE FOR FUTURE SALE

     Before this offering, you could not buy or sell our common stock on a
public market. An active public market for our common stock may not develop or
be sustained after this offering. Future sales of substantial amounts of common
stock, including shares issued upon exercise of outstanding options or warrants,
in the public market after this offering could adversely affect the prevailing
market price of our common stock and could impair our ability to raise equity
capital in the future. In addition, since few shares will be available for sale
immediately after this offering due to the contractual and legal restrictions on
resale described below, sales of substantial amounts of our common stock in the
public market after the restrictions lapse could adversely affect the prevailing
market price and our ability to raise equity capital in the future.


     Upon completion of this offering, we will have outstanding 17,203,690
shares of common stock based on shares outstanding at June 30, 1999, assuming no
exercise of the underwriters' over-allotment option and no exercise of
outstanding options or warrants. Of this amount, the 4,000,000 shares sold in
this offering will be freely tradable in the public market without restriction
or further registration under the Securities Act, unless those shares are
purchased by any of our affiliates. An affiliate of Broadbase is a person that
directly, or indirectly through one or more intermediaries, controls, or is
controlled by, or is under common control with, Broadbase. Our current
affiliates include the individuals and entities that holds more than 10% of our
stock listed under "Principal Stockholders" as well as our other executive
officers and directors. The remaining 13,203,690 shares held by existing
stockholders are subject to various resale restrictions. Of these shares, all
shares are subject to lock-up agreements with the underwriters or directly with
the Company, under which all of our directors and officers and stockholders have
agreed not to transfer or dispose of, directly or indirectly, any shares of
common stock or any securities convertible into or exercisable or exchangeable
for shares of common stock, for a period of 180 days after the date of this
prospectus. Deutsche Bank Securities Inc., in some instances together with us,
may release the shares subject to the lock-up agreements in whole or in part at
any time with or without notice. After expiration or release of the lock-up
agreements, 10,284,667 of the shares held by our existing stockholders will be
eligible for sale in the public market under Rule 144 or Rule 701 beginning 180
days after the date of this prospectus, although 8,793,961 of these shares will
be subject to volume limitations. The remaining 2,919,023 shares held by our
existing stockholders will become eligible for public sale, subject in most
cases to volume limitations, on subsequent dates.


  RULE 144

     In general, under Rule 144, beginning 90 days after the date of this
prospectus, stockholders of Broadbase that have beneficially owned their shares
for at least one year, but less than two years, and affiliates of Broadbase that
have beneficially owned their shares for any period of more than one year, would
be entitled to sell within any three-month period a number of shares that does
not exceed the greater of:


     - 1% of the number of shares of common stock then outstanding, equal to
       approximately 172,036 shares immediately after this offering; or


     - the average weekly trading volume of the common stock on the Nasdaq
       National Market during the four calendar weeks preceding the filing of a
       notice of sale with the SEC.

     Sales under Rule 144 are also subject to manner of sale provisions and
notice requirements and to the availability of current public information about
us.

                                       63
<PAGE>   67

  RULE 144(K)


     Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner except one of our affiliates, is
entitled to sell those shares without complying with the volume limitation or
the manner of sale, public information or notice provisions of Rule 144.


  RULE 701

     In general, under Rule 701 of the Securities Act, any of our employees,
officers, directors, consultants or advisors who purchased shares from us in
connection with a compensatory stock or option plan or other written agreement
is eligible to resell those shares 90 days after the effective date of this
offering in reliance on Rule 144, but without compliance with certain
restrictions, including the holding period contained in Rule 144. However, all
shares issued pursuant to Rule 701 are subject to lock-up agreements and will
only become eligible for sale at the earlier of the expiration of the 180-day
lock-up agreements or obtaining the prior written consent of Deutsche Bank
Securities Inc.

REGISTRATION RIGHTS


     At any time more than six months after the closing of this offering, the
holders of 9,991,146 shares of our common stock and warrants to acquire common
stock, or their transferees, will be entitled to rights to register their shares
under the Securities Act. See "Description of Capital Stock--Registration
Rights." After registration, these shares could be sold without restriction
under the Securities Act.


STOCK OPTIONS


     Promptly following this offering, we will file a registration statement
under the Securities Act covering all shares of common stock subject to
outstanding options or reserved for issuance under our 1996 Equity Incentive
Plan, our 1999 Equity Incentive Plan and our 1999 Employee Stock Option Plan.
Based on the number of shares subject to options outstanding or reserved for
issuance under these plans, at June 30, 1999 this registration statement would
cover approximately 10,523,249 shares. The registration statement will
automatically become effective upon filing. Accordingly, shares registered under
the registration statement will, subject to Rule 144 volume limitations
applicable to our affiliates, be available for sale in the open market
immediately after the 180-day lock-up agreements expire.


WARRANTS


     As of June 30, 1999, we had outstanding warrants to purchase 36,764 shares
of common stock. When these warrants are exercised and the exercise price is
paid in cash the shares must be held for one year before they can be sold under
Rule 144. These warrants also contain "net exercise provisions." These
provisions allow a holder to exercise the warrant for a lesser number of shares
of common stock in lieu of paying cash. The shares of common stock issued in a
"net exercise" could be publicly sold under Rule 144 immediately after exercise,
subject to the 180-day lock-up period.

</TABLE>


     The underwriting agreement provides that the obligations of the several
underwriters to purchase the shares of common stock offered hereby are subject
to certain conditions precedent and that the underwriters will purchase all
shares of the common stock offered hereby, other than those covered by the
over-allotment option described below, if any of these shares are purchased.

     The underwriters propose to offer the shares of common stock to the public
at the public offering price set forth on the cover of this prospectus and to
dealers at a price that represents a concession not in excess of $     per share
under the public offering price. The underwriters may allow, and these dealers
may re-allow, a concession of not more than $     per share to other dealers.
After the initial public offering, representatives of the underwriters may
change the offering price and other selling terms.


     We have granted to the underwriters an option, exercisable not later than
30 days after the date of this prospectus, to purchase up to 600,000 additional
shares of common stock at the public offering price less the underwriting
discounts and commissions set forth on the cover page of this prospectus. The
underwriters may exercise this option only to cover over-allotments made in
connection with the sale of the common stock offered hereby. To the extent that
the underwriters exercise this option, each of the underwriters will become
obligated, subject to conditions, to purchase approximately the same percentage
of additional shares of common stock as the number of shares of common stock to
be purchased by it in the above table bears to the total number of shares of
common stock offered hereby. We will be obligated, pursuant to the option, to
sell these additional shares of common stock to the underwriters to the extent
the option is exercised. If any additional shares of common stock are purchased,
the underwriters will offer the additional shares on the same terms as those on
which the 4,000,000 shares are being offered.



     The underwriting fee is equal to the public offering price per share of
common stock less the amount paid by the underwriters to us per share of common
stock. The underwriting fee is currently expected to be approximately 7.0% of
the initial public offering price. We have agreed


                                       65
<PAGE>   69

to pay the underwriters the following fees, assuming either no exercise or full
exercise by the underwriters of the underwriters' over-allotment option:

     In addition, we estimate that our share of the total expenses of this
offering, excluding underwriting discounts and commissions, will be
approximately $1,055,000.



     We have agreed to indemnify the underwriters against some specified types
of liabilities, including liabilities under the Securities Act and to contribute
to payments the underwriters may be required to make in respect of any of these
liabilities.



     Each of our officers, directors, stockholders and holders of options and
warrants to purchase our stock, has agreed not to offer, sell, contract to sell
or otherwise dispose of, or enter into any transaction that is designed to, or
could be expected to, result in the disposition of any portion of our common
stock held by these persons prior to this offering or common stock issuable upon
exercise of options or warrants held by these persons for a period of 180 days
after the effective date of the registration statement of which this prospectus
is a part without the prior written consent of Deutsche Bank Securities Inc.
This consent may be given at any time without public notice. We have entered
into a similar agreement with the representatives of the underwriters.


     The representatives of the underwriters have advised us that the
underwriters do not intend to confirm sales to any account over which they
exercise discretionary authority.

     In order to facilitate the offering of our common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
market price of our common stock. Specifically, the underwriters may over-allot
shares of our common stock in connection with this offering, thus creating a
short position in our common stock for their own account. A short position
results when an underwriter sells more shares of common stock than that
underwriter is committed to purchase. Additionally, to cover these
over-allotments or to stabilize the market price of our common stock, the
underwriters may bid for, and purchase, shares of our common stock in the open
market. Finally, the representatives, on behalf of the underwriters, may also
reclaim selling concessions allowed to an underwriter or dealer if the
underwriting syndicate repurchases shares distributed by that underwriter or
dealer. Any of these activities may maintain the market price of our common
stock at a level above that which might otherwise prevail in the open market.
These transactions may be effected on the Nasdaq National Market or otherwise.
The underwriters are not required to engage in these activities and, if
commenced, may end any of these activities at any time.


     A prospectus in electronic format is being made available on Internet
websites maintained by E*OFFERING Corp. and E*TRADE Securities, Inc. Internet
purchases of the common stock offered by this prospectus will be available only
to registered customers of E*TRADE who possess sufficient net worth and
investment experience. All eligible accounts may submit a conditional offer to
E*TRADE to purchase shares. If demand exceeds availability, E*TRADE will
randomly allocate shares to applicants in 100 share lots in a round-robin
fashion, meaning that no applicant will receive a second lot until all
applicants have received one lot and so forth, until all shares available to
E*TRADE have been distributed. The common stock offered by this prospectus will
not be directed to any additional Internet customers other than the registered
customers of E*TRADE mentioned above.

     At our request, the underwriters have reserved for sale, at the initial
public offering price, up to (1) 200,000 shares for friends and family members

market, sell or otherwise promote our products and (2) up to 384,644 additional
shares for certain current stockholders under their pre-existing contractual
rights to purchase shares in this offering. None of these shares will be subject

shares are purchased. Any reserved shares that are not purchased by these
persons will be offered by the underwriters to the general public on the same
basis as the other shares in this offering.

preferred stock is convertible at the option of the holder into one share of our

our Series E preferred stock in the private placement. Pursuant to the rules of

Accordingly, these shares cannot be sold, transferred, assigned, pledged or
hypothecated by any person for a period of one year after the effective date of
this offering, except to officers or partners of the underwriters and members of
the selling group and their officers or partners.

PRICING OF THIS OFFERING


     Prior to this offering, there has been no public market for our common
stock. Consequently, the initial public offering price for our common stock will
be determined by negotiation among us and the representatives of the
underwriters. Among the primary factors to be considered in determining the
public offering price will be:


     - prevailing market conditions;

     - our results of operations in recent periods;

     - the present stage of our development;

     - the market capitalizations and stages of development of other companies
       that we and the representatives of the underwriters believe to be
       comparable to our business; and

     - estimates of our business potential.

The estimated initial public offering price range set forth on the cover of this
preliminary prospectus is subject to change as a result of market conditions and
other factors.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Shareholders
BroadBase Information Systems, Inc.

     We have audited the accompanying consolidated balance sheets of BroadBase
Information Systems, Inc. as of December 31, 1997 and 1998, and the related
consolidated statements of operations, cash flows, and shareholders' equity (net
capital deficiency) for the period from November 28, 1995 (inception) to
December 31, 1996 and for each of the two 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 BroadBase
Information Systems, Inc. at December 31, 1997 and 1998, and the results of its
operations and its cash flows for the period from November 28, 1995 (inception)
to December 31, 1996 and for the each of the two years in the period ended
December 31, 1998, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                    (INFORMATION AS OF JUNE 30, 1999 AND FOR


           THE SIX MONTHS ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)


1. SUMMARY OF THE COMPANY AND SIGNIFICANT ACCOUNTING POLICIES

  THE COMPANY


     BroadBase Information Systems, Inc. (the "Company") was incorporated on
November 28, 1995 and develops and markets software that integrates and analyzes
customer information from Internet and traditional business channels, enabling
businesses to improve their customer acquisition, retention, and profitability.
Through December 31, 1997, the Company was in the development stage. During
1998, the Company sold its first product and, accordingly, is no longer
classified as a development stage company. The Company has incurred operating
losses to date, including a net loss of $11,343,000 for the year ended December
31, 1998. The Company's activities have been financed primarily through private
placements of equity and debt securities. Management recognizes the need for
additional financing and will pursue various funding options including both
private and public equity and debt financings. In the longer term, the Company
plans to finance operations with revenues from product sales.


  BASIS OF PRESENTATION

     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiaries. The Company has export sales from the United
States and has operations in Japan and the United Kingdom. All significant
intercompany transactions and balances have been eliminated.

  INTERIM FINANCIAL INFORMATION


     The financial information as of June 30, 1999 and for the six months ended
June 30, 1998 and 1999 is unaudited but includes all adjustments, consisting of
only normal recurring adjustments, that in the opinion of management is
necessary for a fair presentation of the Company's financial position, operating
results, and cash flows for such periods. Operating results for the six month
period ended June 30, 1999 are not necessarily indicative of results to be
expected for the full fiscal year of 1999 or any future period.


  USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ materially from those estimates.

  REVENUE RECOGNITION


     The Company recognizes revenue in accordance with the American Institute of
Certified Public Accountants' Statement of Position 97-2, "Software Revenue
Recognition" ("SOP 97-2"), as amended by Statement of Position 98-4, "Deferral
of the Effective Date of a Provision of SOP 97-2" ("SOP 98-4"). The Company
derives revenue from the sale of software licenses, post-contract support
("maintenance"), and other professional services.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                    (INFORMATION AS OF JUNE 30, 1999 AND FOR


           THE SIX MONTHS ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)



Maintenance includes telephone technical support, bug fixes and rights to
upgrades and enhancements on a when-and-if available basis. Professional
services include training and basic post-implementation consulting to meet
specific customer needs.



     Revenue from license fees is recognized when persuasive evidence of an
agreement exists, delivery of the product has occurred, no significant company
obligations with regard to installation or implementation of the software
remain, the fee is fixed or determinable and collectibility is probable. Revenue
on arrangements with customers that are not the ultimate end users (primarily
resellers) is recognized upon receipt of a reseller report of the sale and the
Company's shipment of the licensed software. Advance payments are recorded as
deferred revenue until the products are shipped, services are delivered or
obligations are met. The Company's products do not require significant
customization.



     Revenue related to maintenance is recognized on a straight-line basis over
the period maintenance is provided and revenue allocable to professional
services is recognized as the services are performed.


     In December 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position 98-9, "Modification of SOP 97-2, Software
Revenue Recognition, With Respect to Certain Transactions" ("SOP 98-9"). SOP
98-9 requires use of the "residual method" for recognition of revenue when
vendor-specific objective evidence exists for undelivered elements but does not
exist for delivered elements of a software arrangement. The Company will be
required to comply with the provisions of SOP 98-9 for transactions entered into
beginning January 1, 2000. The Company has not yet determined the effect of the
adoption of SOP 98-9 on its financial position or operating results. However,
SOP 98-9 may require more revenue to be deferred for certain types of
transactions.

  CONCENTRATIONS OF CREDIT RISK AND CREDIT EVALUATIONS


     Financial instruments which subject the Company to concentrations of credit
risk primarily consist of cash, cash equivalents and accounts receivable. The
Company maintains its cash and cash equivalents principally in domestic
financial institutions of high credit standing. The Company's accounts
receivables are derived primarily from sales of software products and services.
The Company performs ongoing credit evaluations of its customers and generally
does not require collateral.



     A limited number of customers has accounted for a substantial portion of
the Company's revenues. The Company had no revenue for the year ended December
31, 1997. One customer accounted for 18% and 11%, of total revenue for the year
ended December 31, 1998 and the six months ended June 30, 1999, respectively.
Another customer accounted for 10% of total revenue for the year ended December
31, 1998. Sales of the Company's products will vary as a result of fluctuations
in market demand for such products and technology. Further, the markets in which
the Company competes are characterized by rapid technological change and intense
competition.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                    (INFORMATION AS OF JUNE 30, 1999 AND FOR


           THE SIX MONTHS ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)


  CASH AND CASH EQUIVALENTS


     Cash equivalents consist of money market funds. The Company considers all
highly liquid investments with an original maturity date of three months or less
to be cash equivalents. The fair value, based on quoted market prices, of the
cash equivalents is approximately equal to their carrying value at December 31,
1997 and 1998 and June 30, 1999.


  SOFTWARE DEVELOPMENT COSTS

     Statement of Financial Accounting Standards No. 86, "Accounting for the
Costs of Computer Software to Be Sold, Leased or Otherwise Marketed," requires
capitalization of certain software development costs subsequent to the
establishment of technological feasibility. Based upon the Company's product
development process, technological feasibility is established upon completion of
a working model. Costs incurred by the Company between the establishment of
technological feasibility and the point at which the product is ready for
general release have been insignificant. Accordingly, the Company has charged
all such costs to research and development expenses in the accompanying
statements of operations.

  INCOME TAXES

     The Company accounts for income taxes in accordance with Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("FAS
109"), which requires the use of the liability method in accounting for income
taxes. Under FAS 109, deferred tax assets and liabilities are measured based on
differences between the financial reporting and tax bases of assets and
liabilities using enacted tax rates and laws that are expected to be in effect
when the differences are expected to reverse.

  STOCK-BASED COMPENSATION

     The Company accounts for stock-based awards to employees under the
intrinsic value method in accordance with Accounting Principles Board Opinion
No. 25, "Accounting for Stock Issued to Employees" ("APB 25"), and has adopted
the disclosure-only alternative of Statement of Financial Accounting Standards
No. 123, "Accounting for Stock-Based Compensation" ("FAS 123").

  ADVERTISING EXPENSES


     The Company expenses advertising costs in the period in which they are
incurred. Advertising expenses for 1997, 1998, and the six months ended June 30,
1999 were approximately $0, $57,000 and $1,000, respectively.


  FOREIGN CURRENCY TRANSLATION

     Assets and liabilities of the Company's wholly-owned foreign subsidiaries
are translated from their functional currencies at exchange rates in effect at
the balance sheet date, and revenues and expenses are translated at average
exchange rates prevailing during the year. Resulting translation adjustments are
reflected as a separate component of shareholders' equity

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

                    (INFORMATION AS OF JUNE 30, 1999 AND FOR


           THE SIX MONTHS ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)


(net capital deficiency). Foreign currency transaction gains and losses, which
have not been material, are included in results of operations.

  NET LOSS PER SHARE

     Basic and diluted net loss per share are presented in conformity with
Statement of Financial Accounting Standards No. 128, "Earnings Per Share" ("FAS
128") for all periods presented. Pursuant to Securities and Exchange Commission
Staff Accounting Bulletin No. 98, common stock and convertible preferred stock
issued or granted for nominal consideration prior to the anticipated effective
date of the Company's initial public offering must be included in the
calculation of basic and diluted net loss per share as if they had been
outstanding for all periods presented. To date, the Company has not had any
issuances or grants for nominal consideration. In accordance with FAS 128, basic
and diluted net loss per share has been computed using the weighted-average
number of shares of common stock outstanding during the period, less shares
subject to repurchase.

  PRO FORMA NET LOSS PER SHARE AND PRO FORMA SHAREHOLDERS' EQUITY


     Pro forma net loss per share has been computed as described above and also
gives effect, under Securities and Exchange Commission guidance, to the
conversion of convertible preferred stock and convertible debentures not
included above that will automatically convert or which management intends to
convert upon the completion of the Company's initial public offering (using the
if-converted method) from the original date of issuance. If the offering
contemplated by this prospectus is consummated, all of the convertible preferred
stock and convertible debentures outstanding as of June 30, 1999 will be
converted into an aggregate of 8,663,089 and 1,313,793 shares, respectively, of
common stock. Pro forma shareholders' equity at June 30, 1999, as adjusted for
conversion of the convertible preferred stock and convertible debentures, is
disclosed on the accompanying balance sheet. Historical and pro forma basic and
diluted net loss per share are as follows:

     If the Company had reported net income, diluted net income per share would
have included the shares used in the computation of pro forma net loss per share
as well as approximately 661,914, 1,278,889 and 2,050,013 common equivalent
shares related to outstanding options and warrants to purchase common stock not
included above for the years ended December 31, 1997 and 1998 and for the six
months ended June 30, 1999, respectively. The common equivalent shares from
options and warrants would be determined on a weighted-average basis using the
treasury stock method.


  COMPREHENSIVE INCOME (LOSS)


     As of January 1, 1998, the Company adopted Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income" ("FAS 130"). FAS
130 establishes new rules for the reporting and display of comprehensive income
and its components, requiring foreign currency translation adjustments, which
currently are reported in shareholders' equity (net capital deficiency), to be
included in other comprehensive income along with net income (loss). For the
years ended December 31, 1997 and 1998 total other comprehensive loss was
approximately $0 and $37,000, respectively, and for the six months ended June
30, 1999 other comprehensive loss totaled $1,000. Other comprehensive income
(loss) consisted solely of foreign currency translation adjustments.


  SEGMENT INFORMATION

     In June 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 131, "Disclosures about Segments of an
Enterprise and Related Information" ("FAS 131"). FAS 131 changes the way
companies report selected segment information in annual financial statements and
requires companies to report selected segment information in interim financial
reports to shareholders. FAS 131 is effective beginning in the

           THE SIX MONTHS ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)


Company's year ended December 31, 1998. The Company operates solely in one
segment, the development and marketing of customer-centric analytic software
products, and therefore there is no impact to the Company's financial statements
of adopting FAS 131. The Company did not have revenue in the year ended December
31, 1997. For the year ended December 31, 1998, revenue from customers outside
of the United States was approximately $175,000. This revenue was from customers
in Japan.

  PROPERTY AND EQUIPMENT

     The Company records property and equipment at cost and calculates
depreciation using the straight-line method over the estimated useful lives of
the assets, generally three to five years. Equipment held under capital leases
is amortized on a straight-line basis over the shorter of the lease term or the
lives of the respective assets, generally three to five years.


     Property and equipment consist of the following:

     As of December 31, 1998, property and equipment include amounts held under

  RECENT ACCOUNTING PRONOUNCEMENTS


     In March 1998, the Accounting Standards Executive Committee issued
Statement of Position 98-1, "Accounting for the Costs of Computer Software
Developed or Obtained for Internal Use" ("SOP 98-1"). SOP 98-1 requires
companies to capitalize certain qualifying computer software costs that are
incurred during the application development stage and amortize them over the
software's estimated useful life. The Company adopted SOP 98-1 effective January
1, 1999. The adoption of SOP 98-1 did not have a material affect on the
Company's consolidated financial position, results of operations, or cash flows.



     In April 1998, the AICPA issued SOP 98-5, "Reporting the Costs of Start-Up
Activities" ("SOP 98-5"). SOP 98-5 is effective beginning on January 1, 1999,
and requires that start-up costs, capitalized prior to January 1, 1999, be
written off and any future start-up costs be expensed as incurred. The adoption
of SOP 98-5 did not have a material impact on the Company's financial position,
results of operations, or cash flows.


     In June 1998, the Financial Accounting Standards Board issued Financial
Accounting Standards Statement No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("FAS 133"). FAS 133 establishes methods of accounting
for derivative financial instruments and hedging activities related to those
instruments as well as other hedging activities. The

Company will be required to adopt FAS 133 for its year ending December 31, 2001.
However, because the Company does not utilize derivative financial instruments
the Company does not believe the impact of FAS 133 will be material to its
financial position, results of operations, or cash flows.

     Notes payable and line of credit borrowings consist of the following:

</TABLE>



     During 1996 and 1997, the Company secured financing under the terms of
$300,000 and $1,000,000 three-year notes payable, respectively. The notes bear
interest at a rate of 15% and 14%, respectively. Principal and interest
installments are payable monthly and the notes are secured by the tangible
assets of the Company. Of the $684,000 in principal amount of notes payable
outstanding at June 30, 1999, $242,000 is due in 1999 and $442,000 is due in
2000. The carrying value of these note obligations approximates their fair
value.



     In connection with the issuance of the notes, the Company issued warrants
to purchase 12,537 and 24,227 shares of Series A and Series B preferred stock at
prices of $1.67 and $2.68 per share, respectively. These warrants are
immediately exercisable and expire in November 2003 and July 2004, respectively.
At the date of grant, the value ascribed to these warrants was immaterial for
financial statement purposes.



     In July 1998, the Company entered into a loan and security agreement with a
financial institution. The agreement provides for a line of credit not to exceed
$2,000,000 and an equipment line of credit not to exceed $1,000,000. Borrowings
under the line of credit bear interest at the institution's prime lending rate
(7.75% at December 31, 1998), and any borrowings under the equipment line of
credit bear interest at the institution's prime lending rate plus 0.5% (8.25% at
December 31, 1998). All borrowings under this agreement are secured by certain
assets of the Company. As of December 31, 1998, no borrowings were outstanding
and $2,000,000 remained available under the line of credit, and $1,000,000, the
full amount available, has been borrowed under the equipment line of credit. The
equipment line of credit borrowings are due in 36 equal monthly installments of
principal, plus accrued interest, beginning in January 1999 and ending in
December 2001. The carrying value of borrowings under the equipment line of
credit approximates their fair value. The agreement also includes terms
requiring satisfaction of certain financial ratios, and a minimum tangible net
worth requirement, and restricts the Company from paying cash dividends. The
Company was in compliance with these financial covenants at December 31, 1998
and June 30, 1999.

3. CONVERTIBLE DEBENTURES


     In December 1998 and April 1999, the Company issued to investors an
aggregate of $8,250,000 and $1,275,000 respectively, principal amount of
unsecured convertible debentures bearing interest of 10.0% per annum. Interest
on the notes is payable quarterly commencing on January 4, 1999 and July 1,
1999, respectively. The debentures are due on December 9, 2003 and are
convertible, at the holders' option, into shares of the Series D preferred stock
anytime prior to the maturity date. As of December 31, 1998, the difference
between the carrying value and the fair value of the convertible debentures was
immaterial based upon the minimal change in interest rates from the date of
issuance to fiscal year end.



     In the event the Company completes a qualified underwritten public offering
of its common stock with aggregate proceeds of at least $10,000,000, the Company
may, at its option, convert the debentures into shares of Series D preferred
stock. Upon conversion, the investors are entitled to the number of shares of
Series D preferred stock determined by dividing the aggregate amount of each
debenture to be converted by a conversion price of $7.25, subject to certain
future adjustments. As of December 31, 1998 and June 30, 1999, no debentures
have been converted into Series D preferred stock.


4. COMMITMENTS

  LEASES

     The Company leases its principal office under a noncancelable operating
lease agreement that expires in July 2002.


     The gross rental payments under all operating leases were approximately
$114,000, $230,000 and $496,000 for the years ended December 31, 1997 and 1998,
and the six months ended June 30, 1999, respectively. Rental expense, net of
reimbursements from sublessees, was approximately $114,000, $73,000 and $316,000
in 1997 and 1998 and the six months ended June 30, 1999, respectively.


     As of December 31, 1998, minimum lease payments under all noncancelable
lease agreements were as follows:

     Each share of Series A, B, C, D and E preferred stock is convertible at any
time into common stock at the exchange rate in effect at the time of conversion,
currently one-for-one, and is subject to appropriate adjustment for common stock
splits, stock dividends, and similar transactions. Conversion is automatic upon
the closing of an initial public offering of common stock in which the aggregate
gross proceeds to the Company are at least $10,000,000 and the offering price is
at least $11.08 per share.



     Each holder of Series A, B, C and D preferred stock is entitled to the
number of votes equal to the number of shares of common stock into which such
preferred stock is convertible.



     Each holder of preferred stock is entitled to receive, when and as declared
by the Board of Directors, noncumulative dividends at the annual rate of $0.05,
$0.21, $0.44, $0.58 and $0.73 per share of Series A, B, C, D and E preferred
stock, respectively, payable in preference and priority to any payment of any
dividend on common stock.


     In the event of liquidation, the holders of preferred stock are entitled to
a liquidation preference equal to the original purchase price of their preferred
stock plus an amount equal to all accrued but unpaid dividends on such shares.

  COMMON STOCK


     In November 1995, 1,282,500 shares of common stock were issued to the
Company's founder at $0.002 per share in exchange for cash. These shares are
subject to certain transfer restrictions. These shares are also subject to
repurchase at the issuance price upon the occurrence of certain events,
including termination of employment. The Company's right of repurchase expires
over four years. At December 31, 1997 and 1998 and June 30, 1999, 553,078,
264,516 and 120,230 shares, respectively, remained subject to repurchase.

  STOCK OPTION PLAN


     During 1996, the Company adopted the 1996 Equity Incentive Plan (the
"Plan"). Under the Plan, up to 4,030,000 shares of the Company's common stock
may be granted to eligible participants. Under the Plan, options to purchase
common stock may be granted at no less than 85% of the fair value on the date of
the grant (110% of fair value in certain instances), as determined by the board
of directors. Options generally vest over a 48-month period and have a maximum
term of 10 years.


     As discussed in Note 1, the Company has elected to follow APB 25 and
related interpretations in accounting for its employee stock options because, as
discussed below, the alternative fair value accounting provided for under FAS
123 requires use of option valuation models that were not developed for use in
valuing employee stock options.

     Under APB 25, when the exercise price of the Company's employee stock
options equals the market price of the underlying stock on the date of grant, no
compensation expense is recognized.


     Pro forma information regarding net income is required by FAS 123, which
also requires that the information be determined as if the Company has accounted
for its employee stock options granted subsequent to December 31, 1994 under the
fair value method of that Statement. The fair value of these options was
estimated at the date of grant using the minimum value method option pricing
model with the following weighted-average assumptions for the period from
November 28, 1995 (inception) to December 31, 1996, the years ended December 31,
1997 and 1998 and the six months ended June 30, 1999: risk-free interest rate of
6%; a dividend yield of 0%; and a weighted-average expected life of the option
of four years.

of those options at their respective grant dates and the deemed fair value for
accounting purposes of the shares of common stock subject to such options. Such
amounts are included as a reduction of shareholders' equity and are being
amortized on a graded vesting method. The compensation expense of $1,133,000 and
$2,472,000 during 1998 and the six months ended June 30, 1999, respectively,
relate to options awarded to employees in all operating expense categories, as
well as employees in professional services. These amounts have not been
separately allocated between operating expense categories.

     Realization of deferred tax assets is dependent on future earnings, if any,
the timing and amount of which are uncertain. Accordingly, a valuation allowance
in an amount equal to the net deferred tax assets as of December 31, 1997 and
1998 has been established to reflect these uncertainties. The valuation
allowance increased by $2,400,000 and $3,600,000 during the years ended December
31, 1997 and 1998, respectively.


     As of December 31, 1998, the Company had federal and state net operating
loss carryforwards of approximately $15,400,000 and $10,700,000, respectively.
The Company also had federal and state research and development tax credit
carryforwards of approximately $300,000 and $200,000, respectively. The net
operating loss and tax credit carryforwards will expire at various dates
beginning in 2004, if not utilized.

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

8. RELATED PARTY TRANSACTION

     In April 1998, the Company provided a $400,000 loan to an officer, who is
also a shareholder, in exchange for a nonrecourse promissory note which is
secured by security interest in common stock. The loan is due in April 2000 and
bears interest at 5.51%.

9. EVENTS SUBSEQUENT TO DATE OF AUDITOR'S REPORT (UNAUDITED)


  INITIAL PUBLIC OFFERING



     In July 1999, the Company filed a registration statement with the
Securities and Exchange Commission that would permit the Company to sell shares
of the its common stock in connection with a proposed initial public offering
(IPO). If the offering is consummated under the terms presently anticipated, all
of the outstanding shares of the Company's convertible

           THE SIX MONTHS ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)


preferred stock, including those shares of convertible preferred stock into
which outstanding debentures are convertible, will convert into shares of common
stock on a one-for-one basis upon closing of the proposed IPO. The conversion of
the convertible preferred stock and debentures has been reflected in the
accompanying unaudited pro forma consolidated balance sheet.

  1999 EQUITY INCENTIVE PLAN


     On July 2, 1999, the Board of Directors approved the adoption of the
Company's 1999 Equity Incentive Plan (the "1999 Incentive Plan"), subject to
shareholder approval. A total of 3,500,000 shares of common stock has been
reserved for issuance under the 1999 Incentive Plan, plus, commencing on
December 31, 1999, annual increases equal to 5% of the outstanding shares. The
number of shares authorized for issuance under the 1999 Incentive Plan will be
increased to include any shares reserved under the 1996 Equity Incentive Plan
not issued or subject to outstanding grants on the date of the Company's initial
public offering and any shares issued under the 1996 Equity Incentive Plan that
are forfeited or repurchased by the Company at the original purchase price or
that expire or become unexercisable for any reason without having been exercised
in full. The types of awards that may be made under the 1999 Incentive Plan are
options to purchase shares of common stock, restricted stock and stock bonuses.
The exercise price for incentive stock options may not be less than 100% of the
fair market value of the Company's common stock on the date of grant (85% for
nonstatutory options). In the event of a change in control of the Company, an
option or award under the 1999 Incentive Plan may be assumed or substituted by
the successor corporation. The Company's compensation committee may also
accelerate the vesting of awards upon a change of control transaction.


  1999 EMPLOYEE STOCK PURCHASE PLAN


     On July 2, 1999, the Board of Directors approved the adoption of the
Company's 1999 Employee Stock Purchase Plan (the "1999 Purchase Plan"), subject
to shareholder approval. A total of 500,000 shares of common stock has been
reserved for issuance under the 1999 Purchase Plan, plus, commencing on January
1, 2000, annual increases equal to 1% of the Company's outstanding common shares
on the preceding December 31. The 1999 Purchase Plan permits eligible employees
to acquire shares of the Company's common stock through periodic payroll
deductions of up to 10% of their cash compensation, subject to certain maximum
purchase limitations. Each offering period will have a maximum duration of 24
months and will consist of four six-month purchase periods. The price at which
the common stock may be purchased is 85% of the lesser of the fair market value
of the Company's common stock on the first day of the applicable offering period
or the last day of each respective purchase period. This initial offering period
will begin on the first business day on which price quotations for the Company's
common stock are available on the Nasdaq National Market after the effectiveness
of the initial public offering.


  LEGAL PROCEEDINGS


     On July 21, 1999, Timeline Inc. filed a complaint against the Company in
the United States District Court for the Western Division of Washington,
alleging infringement by the Company of

           THE SIX MONTHS ENDED JUNE 30, 1998 AND 1999 IS UNAUDITED)



one of Timeline's patents. The complaint alleges that the Company directly and
indirectly infringes Timeline's patent claims by making, using, selling and
offering to sell software products, both alone and in combination with third
party software products, and further alleges that the Company induces
infringement of the Timeline patent claims. Timeline has requested permanent
injunctions prohibiting the Company from directly or indirectly infringing the
Timeline patent, and seeks damages, exemplary damages, costs and attorney's
fees. Timeline has further disclosed to the Company claims of a pending related
patent application that Timeline expects to be issued and to be added to the
present case. Based on the Company's investigation of this matter to date, the
Company does not believe its products infringe any valid claims of the Timeline
patent or of the pending patent application, and that it has meritorious
defenses to all claims made by Timeline. The Company intends to defend this suit
vigorously and does not believe the resolution of this matter will have a
material adverse impact on the Company's financial position, results of
operations, or cash flows.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

     Section 145 of the Delaware General Corporation Law authorizes a court to
award, or a corporation's Board of Directors to grant, indemnity to directors
and executive officers in terms sufficiently broad to permit such
indemnification under certain circumstances for liabilities (including
reimbursement for expenses incurred) arising under the Securities Act of 1933,
as amended (the "Securities Act").

     As permitted by the Delaware General Corporation Law, the Registrant's
certificate of incorporation includes a provision that eliminates the personal
liability of its directors for monetary damages for breach of fiduciary duty as
a director, except for liability:

     - for any breach of the director's duty of loyalty to the Registrant or its
       stockholders;

     - for acts or omissions not in good faith or that involve intentional
       misconduct or a knowing violation of law;

     - under Section 174 of the Delaware General Corporation Law (regarding
       unlawful dividends and stock purchases); or

     - for any transaction from which the director derived an improper personal
       benefit.

     As permitted by the Delaware General Corporation Law, the Registrant's
bylaws provide that:

     - the Registrant is required to indemnify its directors and executive
       officers to the fullest extent permitted by the Delaware General
       Corporation Law, subject to certain very limited exceptions;

     - the Registrant may indemnify its other employees and agents as set forth
       in the Delaware General Corporation Law;

     - the Registrant is required to advance expenses, as incurred, to its
       directors and officers in connection with a legal proceeding to the
       fullest extent permitted by the Delaware General Corporation Law, subject
       to certain very limited exceptions; and

     - the rights conferred in the bylaws are not exclusive.

                                      II-1
<PAGE>   98

     The Registrant intends to enter into indemnification agreements with each
of its current directors and executive officers to give such directors and
executive officers additional contractual assurances regarding the scope of the
indemnification set forth in the Registrant's certificate of incorporation and
to provide additional procedural protections. At present, there is no pending
litigation or proceeding involving a director, officer or employee of the
Registrant regarding which indemnification is sought, nor is the Registrant
aware of any threatened litigation that may result in claims for
indemnification.


     Reference is also made to the Underwriting Agreement, which provides for
the indemnification of officers, directors and controlling persons of the
Registrant against certain liabilities. The indemnification provision in the
Registrant's certificate of incorporation, bylaws and the indemnity agreements
to be entered into between the Registrant and each of its directors and
executive officers may be sufficiently broad to permit indemnification of the
Registrant's directors and executive officers for liabilities arising under the
Securities Act.



     The Registrant expects to obtain directors' and officers' liability
insurance that will include coverage for securities matters.


     See also the undertakings set out in response to Item 17.

     Reference is made to the following documents filed as exhibits to this
Registration Statement regarding relevant indemnification provisions described
above and elsewhere herein:

ITEM 17. UNDERTAKINGS.

     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.

     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 under Item 14 above, 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 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 that:

     (1) For purposes of determining any liability under the Securities Act, the
information omitted from the form of prospectus filed as part of this
Registration Statement in reliance upon Rule 430A and contained in a form of
prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h)
under the Securities Act shall be deemed to be part of this Registration
Statement as of the time it was declared effective.

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

        2. DIVIDEND RIGHTS.

               2.1 Preferred Stock. In each calendar year, the holders of the
then outstanding Preferred Stock shall be entitled to receive, when, as and if
declared by the Board, out of any funds and assets of the Corporation legally
available therefor, noncumulative dividends at the applicable annual Dividend
Rate for the Series A Preferred Stock, the Series B Preferred Stock, the Series
C Preferred Stock, the Series D Preferred Stock and the Series E Preferred
Stock, respectively, prior and in preference to the payment of any dividends on
the Common Stock in such calendar year (other than a Common Stock Dividend). No
dividends (other than a Common Stock Dividend) shall be paid with respect to the
Common Stock during any calendar year unless dividends in the total amount of
the annual Dividend Rate for the Series A Preferred Stock, the Series B
Preferred Stock, the Series C Preferred Stock, the Series D Preferred Stock and
the Series E Preferred Stock shall have first been paid or declared and set
apart for payment to the holders of the Series A Preferred Stock, the Series B
Preferred Stock, the Series C Preferred Stock, the Series D Preferred Stock and
the Series E Preferred Stock, respectively, during that calendar year. Dividends
on the Preferred Stock shall not be mandatory or cumulative, and no rights or
interest shall accrue to the holders of the Preferred Stock by reason of the
fact that the Corporation shall fail to declare or pay dividends on the
Preferred Stock in the amount of the applicable annual Dividend Rate or in any
other amount in any calendar year or any fiscal year of the Corporation, whether
or not the earnings of the Corporation in any calendar year or fiscal year were
sufficient to pay such dividends in whole or in part. Payments of any dividends
to the holders of Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock, the Series D Preferred Stock and the Series E Preferred Stock
shall be paid pro rata, on an equal priority, pari passu basis according to the
respective Dividend Rates as set forth herein.

               2.2 Participation Rights. If, after dividends in the full
preferential amount specified in this Section 2 for the Preferred Stock have
been paid or declared and set apart in any calendar year of the Corporation, the
Board shall declare additional dividends out of funds legally available therefor
in that calendar year, then such additional dividends shall be declared pro rata
on the Common Stock and the Preferred Stock on a pari passu basis according to
the number of shares of Common Stock held by such holders, where each holder of
shares of Preferred Stock is to be treated for this purpose as holding the
greatest whole number of shares of Common Stock then issuable upon conversion of
all shares of Preferred Stock held by such holder pursuant to Section 5.

               2.3 Non-Cash Dividends. Whenever a dividend provided for in this
Section 2 shall be payable in property other than cash, the value of such
dividend shall be deemed to be the fair market value of such property as
determined in good faith by the Board.

        3. LIQUIDATION RIGHTS. In the event of any liquidation, dissolution or
winding up of the Corporation, whether voluntary or involuntary, the funds and
assets of the Corporation that

                                                      Certificate of Designation

may be legally distributed to the Corporation's stockholders (the "Available
Funds and Assets") shall be distributed to stockholders in the following manner:

               3.1 Preferred Stock. The holders of each share of Preferred Stock
then outstanding shall be entitled to be paid, out of the Available Funds and
Assets, and prior and in preference to any payment or distribution (or any
setting apart of any payment or distribution) of any Available Funds and Assets
on any shares of Common Stock, an amount per share equal to the Original Issue
Price of the applicable series of Preferred Stock plus all declared but unpaid
dividends per share on that series of Preferred Stock. If upon any liquidation,
dissolution or winding up of the Corporation, the Available Funds and Assets
shall be insufficient to permit the payment to holders of the Series A Preferred
Stock, the Series B Preferred Stock, the Series C Preferred Stock, the Series D
Preferred Stock and the Series E Preferred Stock of their full preferential
amount described in this subsection, then all of the remaining Available Funds
and Assets shall be distributed among the holders of the then outstanding Series
A Preferred Stock, the holders of the then outstanding Series B Preferred Stock,
the holders of the then outstanding Series C Preferred Stock, the holders of the
then outstanding Series D Preferred Stock and the holders of the then
outstanding Series E Preferred Stock, pro rata according to the aggregate
preferential amount to which each holder is entitled.

               3.2 Remaining Assets. If there are any Available Funds and Assets
remaining after the payment or distribution (or the setting aside for payment or
distribution) to the holders of the Preferred Stock of their full preferential
amounts described above in this Section 3, then all such remaining Available
Funds and Assets shall be distributed among the holders of the then outstanding
Common Stock, pro rata according to the number of shares of Common Stock held by
each holder thereof.

               3.3 Merger or Sale of Assets. A (i) consolidation or merger of
the Corporation with or into any other corporation or corporations in which the
holders of the Corporation's outstanding shares immediately before such
consolidation or merger do not, immediately after such consolidation or merger,
retain stock representing a majority of the voting power of the surviving
corporation (or the parent corporation of such surviving corporation if the
surviving corporation is wholly-owned by the parent) of such consolidation or
merger; or (ii) sale of all or substantially all of the assets of the
Corporation, shall each be deemed to be a liquidation, dissolution or winding up
of the Corporation as those terms are used in this Section 3.

               3.4 Non-Cash Consideration. If any assets of the Corporation
distributed to stockholders in connection with any liquidation, dissolution or
winding up of the Corporation are other than cash, then the value of such assets
shall be their fair market value as determined by the Board, except that any
securities to be distributed to stockholders in a liquidation, dissolution or
winding up of the Corporation shall be valued as follows:

                      (a) The method of valuation of securities not subject to
investment letter or other similar restrictions on free marketability shall be
as follows:

                           (i) if the securities are then traded on a national
securities exchange or the Nasdaq National Market (or a similar national
quotation system), then the value shall be deemed to be the average of the
closing prices of the securities on such exchange or system over the 30-day
period ending three (3) days prior to the distribution; and

                           (ii) if actively traded over-the-counter, then the
value shall be deemed to be the average of the closing bid prices over the
30-day period ending three (3) days prior to the distribution; and

                           (iii) if there is no active public market, then the
value shall be the fair market value thereof, as determined in good faith by the
Board.

                      (b) The method of valuation of securities subject to
investment letter or other restrictions on free marketability shall be to make
an appropriate discount from the market value determined as above in
subparagraphs (a)(i), (ii) or (iii) of this subsection to reflect the
approximate fair market value thereof, as determined in good faith by the Board.

               3.5 Notice.

                      (a) The corporation shall give each holder of record of
Preferred Stock written notice of any liquidation, dissolution or winding up of
the Corporation or any other transaction described in Section 3.3 not later than
twenty (20) days prior to the stockholders' meeting called to approve such
transaction, or twenty (20) days prior to the closing of such transaction,
whichever is earlier, and shall also notify such holders in writing of the final
approval of such transaction. The first of such notices shall describe the
material terms and conditions of the impending transaction and the provisions of
this Section 3, and the corporation shall thereafter give such holders prompt
notice of any material changes. The transaction shall in no event take place
sooner than twenty (20) days after the corporation has given the first notice
provided for herein or sooner than ten (10) days after the corporation has given
notice of any material changes provided for herein; provided, however, that such
periods may be shortened to no less than two (2) days upon the written consent
of the holders of Preferred Stock that are entitled to such notice rights or
similar rights and that represent at least a majority of the voting power of all
then outstanding shares of such Preferred Stock.

                      (b) In the event the requirements of this Section 3 are
not complied with, this corporation shall forthwith either:

                           (i) cause such closing to be postponed until such
time as the requirements of this Section 3 have been complied with; or

                           (ii) cancel such transaction, in which event the
rights, preferences and privileges of the holders of the Preferred Stock shall
revert to and be the same as such rights, preferences and privileges existing
immediately prior to the date of the first notice referred to in this Section 3.

electing directors, the presence in person or by proxy of the holders of a

or Common Stock then outstanding, respectively, shall constitute a quorum of the
Series A Preferred Stock, Series B Preferred Stock or Common Stock, as the case

Stock and Common Stock shall constitute a quorum for the election of any
directors to be elected jointly by the holders of the Preferred Stock and the
Common Stock.

                           (ii) Required Vote. With respect to the election of
any director or directors by the holders of the outstanding shares of a
specified series of stock given the right to elect such director or directors
pursuant to subsection 4.4(a) above ("Specified Stock"), that candidate or those
candidates (as applicable) shall be elected who either: (i) in the case of any
such vote conducted at a meeting of the holders of such Specified Stock, receive
the highest number of affirmative votes of the outstanding shares of such
Specified Stock, up to the number of directors to be elected by such Specified
Stock; or (ii) in the case of any such vote taken by written consent without a
meeting, are elected by the written consent of the holders of a majority of the
outstanding shares of such Specified Stock.

                      (c) Vacancy. If there shall be any vacancy in the office
of a director elected by the holders of any Specified Stock pursuant to
subsection 4.4(a), then a successor to hold office for the unexpired term of
such director may be elected by either: (i) the remaining director or directors
(if any) in office that were so elected by the holders of such Specified Stock,
by the affirmative vote of a majority of such directors (or by the sole
remaining director elected by the holders of such Specified Stock if there be
but one), or (ii) the required vote of holders of the shares of such Specified
Stock specified in subsection 4.4(b)(ii) above that are entitled to elect such
director under subsection 4.4(a).

                      (d) Removal. Any director who shall have been elected to
the Board by the holders of any Specified Stock pursuant to subsection 4.4(a) or
by any director or directors elected by holders of any Specified Stock as
provided in subsection 4.4(c), may be removed during his or her term of office,
either with or without cause, by, and only by, the affirmative vote of shares
representing a majority of the voting power of all the outstanding shares of
such Specified Stock entitled to vote, given either at a meeting of such
stockholders duly called for that purpose or pursuant to a written consent of
stockholders without a meeting, and any vacancy created by such removal may be
filled only in the manner provided in subsection 4.4(c).

                      (e) Procedures. Any meeting of the holders of any
Specified Stock, and any action taken by the holders of any Specified Stock by
written consent without a meeting, in order to elect or remove a director under

Law and applicable law regarding stockholder meetings and stockholder actions by
written consent, as such are then in effect (including but not limited to
procedures and provisions for determining the record date for shares entitled to
vote).

                      (f) Termination. Notwithstanding anything in this
subsection 4.4 to the contrary, the provisions of this subsection 4.4 shall
cease to be of any further force or effect upon the first date that either there

stockholders of the Corporation in compliance with applicable law and the
Certificate of Incorporation and Bylaws of the Corporation; (ii) a sale of all
or substantially all of the Corporation's assets; or (iii) immediately prior to
the closing of an IPO (as defined in Section 5.2(a)). Further, to the extent
that (i) the number of outstanding shares of Series A Preferred Stock is reduced

dividends, splits or combinations), the provisions of Section 4.4(a)(i) shall
terminate and cease to be of any further force or effect; (ii) the number of
outstanding shares of Series B Preferred Stock is reduced to less than 500,000
shares (subject to appropriate adjustment to reflect stock dividends, splits or
combinations), the provisions of Section 4.4(a)(ii) shall terminate and cease to
be of any further force or effect; and (iii) the number of outstanding shares of
Common Stock is reduced to less than 500,000 shares (subject to appropriate
adjustment to reflect stock dividends, splits or combinations), the provisions

        5. CONVERSION RIGHTS. The outstanding shares of Preferred Stock shall be
convertible into Common Stock as follows:

               5.1 Optional Conversion.

                      (a) At the option of the holder thereof, each share of
Preferred Stock shall be convertible, at any time or from time to time prior to
the close of business on the business day before any date fixed for redemption
of such share, into fully paid and nonassessable shares of Common Stock as
provided herein.

                      (b) Each holder of Preferred Stock who elects to convert
the same into shares of Common Stock shall surrender the certificate or
certificates therefor, duly endorsed, at the office of the Corporation or any
transfer agent for the Preferred Stock or Common Stock, and shall give written
notice to the Corporation at such office that such holder elects to convert the
same and shall state therein the number of shares of Preferred Stock being
converted. Thereupon the Corporation shall promptly issue and deliver at such
office to such holder a certificate or certificates for the number of shares of
Common Stock to which such holder is entitled upon such conversion. Such
conversion shall be deemed to have been made immediately prior to the close of
business on the date of such surrender of the certificate or certificates
representing the shares of Preferred Stock to be converted, and the person
entitled to receive the shares of Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder of such shares of Common
Stock on such date.

               5.2 Automatic Conversion.

                      (a) (i) Each share of Preferred Stock shall automatically
be converted into fully paid and nonassessable shares of Common Stock, as
provided herein immediately prior to the closing of a firm commitment
underwritten public offering pursuant to an effective registration statement
filed under the Securities Act of 1933, as amended, covering the offer and sale
of Common Stock for the account of the Corporation in which the aggregate public
offering price (before deduction of underwriters' discounts and commissions)
equals or exceeds $10,000,000 and the public offering price per share of which
equals or exceeds $11.08 per share before deduction of underwriters' discounts
and commissions (such price per share of Common Stock to be appropriately
adjusted to reflect Common Stock Events (as defined in subsection 5.4)) (the
"IPO").

                           (ii) Each share of Preferred Stock (other than the
Series E Preferred Stock) shall automatically be converted into fully paid and
nonassessable shares of Common Stock, as provided herein upon the Corporation's
receipt of the written consent of the holders of not less than two-thirds (2/3)
of the then outstanding shares of Preferred Stock (other than the Series E
Preferred Stock) to the conversion of all then outstanding Preferred Stock
(other than the Series E Preferred Stock) under this Section 5.

                           (iii) Each share of Series E Preferred Stock shall
automatically be converted into fully paid and nonassessable shares of Common
Stock, as provided herein upon the Corporation's receipt of the written consent
of the holders of not less than a majority of the then outstanding shares of
Series E Preferred Stock to the conversion of all then outstanding Series E
Preferred Stock under this Section 5.

                      (b) Upon the occurrence of any event specified in
subparagraph 5.2(a)(i), (ii), or (iii) above, the outstanding shares of the
applicable series of Preferred Stock shall be converted into Common Stock
automatically without the need for any further action by the holders of such
shares and whether or not the certificates representing such shares are
surrendered to the Corporation or its transfer agent; provided, however, that
the Corporation shall not be obligated to issue certificates evidencing the
shares of Common Stock issuable upon such conversion unless the certificates
evidencing such shares of the applicable series of Preferred Stock are either
delivered to the Corporation or its transfer agent as provided below, or the
holder notifies the Corporation or its transfer agent that such certificates
have been lost, stolen or destroyed and executes an agreement satisfactory to
the Corporation to indemnify the Corporation from any loss incurred by it in
connection with such certificates. Upon the occurrence of such automatic
conversion of the applicable series of Preferred Stock, the holders of such
Preferred Stock shall surrender the certificates representing such shares at the
office of the Corporation or any transfer agent for the Preferred Stock or
Common Stock. Thereupon, there shall be issued and delivered to such holder
promptly at such office and in its name as shown on such surrendered certificate
or certificates, a certificate or certificates for the number of shares of
Common Stock into which the shares of the applicable series of Preferred Stock
surrendered were convertible on the date on which such automatic conversion
occurred.

                                                      Certificate of Designation

               5.3 Conversion Price. Each share of Preferred Stock shall be
convertible in accordance with subsection 5.1 or subsection 5.2 above into the
number of shares of Common Stock which results from dividing the Original Issue
Price for such series of Preferred Stock by the conversion price for such series
of Preferred Stock that is in effect at the time of conversion (the "Conversion
Price"). The initial Conversion Price for the Series A Preferred Stock shall be
the Original Issue Price for the Series A Preferred Stock. The initial
Conversion Price for the Series B Preferred Stock shall be the Original Issue
Price for the Series B Preferred Stock. The initial Conversion Price for the
Series C Preferred Stock shall be the Original Issue Price for the Series C
Preferred Stock. The initial Conversion Price for the Series D Preferred Stock
shall be the Original Issue Price for the Series D Preferred Stock. The initial
Conversion Price for the Series E Preferred Stock shall be the Original Issue
Price for the Series E Preferred Stock. The Conversion Price of each series of
Preferred Stock shall be subject to adjustment from time to time as provided
below.

               5.4 Adjustment Upon Common Stock Event. Upon the happening of a
Common Stock Event (as hereinafter defined) after the effective date of this
amendment, the Conversion Price of each series of Preferred Stock shall,
simultaneously with the happening of such Common Stock Event, be adjusted by
multiplying the Conversion Price of such series of Preferred Stock in effect
immediately prior to such Common Stock Event by a fraction, (i) the numerator of
which shall be the number of shares of Common Stock issued and outstanding
immediately prior to such Common Stock Event, and (ii) the denominator of which
shall be the number of shares of Common Stock issued and outstanding immediately
after such Common Stock Event, and the product so obtained shall thereafter be
the Conversion Price for such series of Preferred Stock. The Conversion Price
for each series of Preferred Stock shall be readjusted in the same manner upon
the happening of each subsequent Common Stock Event. As used herein, the term
"Common Stock Event" shall mean (i) the issue by the Corporation of additional
shares of Common Stock as a dividend or other distribution on outstanding Common
Stock, (ii) a subdivision of the outstanding shares of Common Stock into a
greater number of shares of Common Stock, or (iii) a combination of the
outstanding shares of Common Stock into a smaller number of shares of Common
Stock.

               5.5 Adjustments for Other Dividends and Distributions. If at any
time or from time to time after the Original Issue Date the Corporation pays a
dividend or makes another distribution to the holders of the Common Stock
payable in securities of the Corporation other than shares of Common Stock, then
in each such event provision shall be made so that the holders of each series of
Preferred Stock shall receive upon conversion thereof in addition to the number
of shares of Common Stock receivable upon conversion thereof, the amount of
securities of the Corporation which they would have received had their Preferred
Stock been converted into Common Stock on the date of such event (or such record
date, as applicable) and had they thereafter, during the period from the date of
such event (or such record date, as applicable) to and including the conversion
date, retained such securities receivable by them as aforesaid during such
period, subject to all other adjustments called for during such period under
this Section 5 with respect to the rights of the holders of the Preferred Stock
or with respect to such other securities by their terms.

               5.6 Adjustment for Reclassification, Exchange and Substitution.
If at any time or from time to time after the Original Issue Date the Common
Stock issuable upon the conversion of any series of Preferred Stock is changed
into the same or a different number of shares of any class or classes of stock,
whether by recapitalization, reclassification or otherwise (other than by a
Common Stock Event or a stock dividend provided for elsewhere in this Section
5), then in any such event each holder of such series of Preferred Stock shall
have the right thereafter to convert such Preferred Stock into the kind and
amount of stock and other securities and property receivable upon such
recapitalization, reclassification or other change by holders of the number of
shares of Common Stock into which such shares of Preferred Stock could have been
converted immediately prior to such recapitalization, reclassification or
change, all subject to further adjustment as provided herein or with respect to
such other securities or property by the terms thereof.

               5.7 Sale of Shares Below Conversion Price.

                      (a) Adjustment Formula. If at any time or from time to
time after the Original Issue Date the Corporation issues or sells, or is deemed
by the provisions of this subsection 5.7 to have issued or sold, Additional
Shares of Common Stock (as hereinafter defined), otherwise than in connection
with a Common Stock Event as provided in subsection 5.4, a dividend or
distribution as provided in subsection 5.5 or a recapitalization,
reclassification or other change as provided in subsection 5.6, for an Effective
Price (as hereinafter defined) that is less than the Conversion Price for a
series of Preferred Stock in effect immediately prior to such issue or sale,
then:

                           (x) in the event that such issuance or sale (a
"Triggering Issuance") occurs after the Corporation has in one or more
transactions issued or sold (together, the "Minimum Issuances"), following the
Series C Original Issue Date, a number of such Additional Shares of Common
Stock, for an Effective Price of less than the Conversion Price of the Series C
Preferred Stock in effect immediately prior to the applicable Minimum Issuance,
for an Aggregate Consideration Received (as hereinafter defined) for all such
Minimum Issuances in excess of an aggregate of $300,000, then (A) if the
Effective Price of such Triggering Issuance is greater than $3.47 per share
(subject to appropriate adjustment to reflect stock dividends, splits or
combinations), the Conversion Price of the Series C Preferred Stock shall be
reduced, as of the close of business on the date of such Triggering Issuance, to
the Effective Price of such Triggering Issuance or (B) if such Effective Price
is less than $3.47 per share (subject to appropriate adjustment to reflect stock
dividends, splits or combinations), the Conversion Price of the Series C
Preferred Stock shall be reduced, as of the close of business on the date of
such Triggering Issuance, to $3.47 and shall then be subject to adjustment
pursuant to subdivision 5.7(a)(z) hereof. After the Conversion Price of the
Series C Preferred Stock has been reduced pursuant to this Section 5.7(a)(x) to
$3.47 (subject to appropriate adjustment to reflect stock dividends, splits or
combinations), this Section 5.7(a)(x) shall no longer apply and Section
5.7(a)(z) shall instead apply. Notwithstanding the foregoing, this subdivision
5.7(a)(x) shall no longer apply, and thereafter subdivision 5.7(a)(z) shall
apply, in the event of the earlier of (A) three years after the Series C
Original Issue Date or (B) the date the Corporation receives proceeds from one
or more financings that are equal to or in excess of an aggregate of $8 million

and which value the Corporation immediately prior to each such financing at an
amount which is equal to or in excess of $80 million (calculated by multiplying
the price per share paid in such financing by the sum, immediately prior to such
financing, of the total number of Common Stock Equivalents and any shares of
Common Stock reserved for future issuance to employees, officers or directors
of, or contractors, consultants or advisers to, the Corporation or any
Subsidiary pursuant to options or rights not yet granted under stock purchase or
stock option plans, stock bonuses or awards, warrants, contracts or other
arrangements that are approved by the Board).

                           (y) in the event that such issuance or sale (a
"Series E Triggering Issuance") occurs after the Corporation has in one or more
transactions issued or sold (together, the "Series E Minimum Issuances"),
following the Original Issue Date, a number of such Additional Shares of Common
Stock, for an Effective Price of less than the Conversion Price of the Series E
Preferred Stock in effect immediately prior to the applicable Series E Minimum
Issuance, for an Aggregate Consideration Received (as hereinafter defined) for
all such Series E Minimum Issuances in excess of an aggregate of $300,000, then
(A) if the Effective Price of such Series E Triggering Issuance is greater than
$3.47 per share (subject to appropriate adjustment to reflect stock dividends,
splits or combinations), the Conversion Price of the Series E Preferred Stock
shall be reduced, as of the close of business on the date of such Series E
Triggering Issuance, to the Effective Price of such Series E Triggering Issuance
or (B) if such Effective Price is less than $3.47 per share (subject to
appropriate adjustment to reflect stock dividends, splits or combinations), the
Conversion Price of the Series E Preferred Stock shall be reduced, as of the
close of business on the date of such Triggering Issuance, to $3.47 and shall
then be subject to adjustment pursuant to subdivision 5.7(a)(z) hereof. After
the Conversion Price of the Series E Preferred Stock has been reduced pursuant
to this Section 5.7(a)(y) to $3.47 (subject to appropriate adjustment to reflect
stock dividends, splits or combinations), this Section 5.7(a)(y) shall no longer
apply and Section 5.7(a)(z) shall instead apply. Notwithstanding the foregoing,
this subdivision 5.7(a)(y) shall no longer apply, and thereafter subdivision
5.7(a)(z) shall apply, in the event of the earlier of (A) three years after the
Series C Original Issue Date, or (B) the date the Corporation receives proceeds
from one or more financings that are equal to or in excess of an aggregate of $8
million and which value the Corporation immediately prior to each such financing
at an amount which is equal to or in excess of $80 million (calculated by
multiplying the price per share paid in such financing by the sum, immediately
prior to such financing, of the total number of Common Stock Equivalents and any
shares of Common Stock reserved for future issuance to employees, officers or
directors of, or contractors, consultants or advisers to, the Corporation or any
Subsidiary pursuant to options or rights not yet granted under stock purchase or
stock option plans, stock bonuses or awards, warrants, contracts or other
arrangements that are approved by the Board), or (C) the date the Corporation
receives proceeds from the sale, in one or more financings (whether on the
Original Issue Date or thereafter) of at least 875,993 shares of Series E
Preferred Stock at a price per share equal to the Series E Preferred Stock
Original Issue Price.

                           (z) in each and every other case not covered by
subdivisions 5.7(a)(x) and (y), the Conversion Price for such series of
Preferred Stock shall be reduced, as of

the close of business on the date of such issue or sale, to the price obtained
by multiplying such Conversion Price by a fraction:

                (i)     The numerator of which shall be the sum of (A) the
                        number of Common Stock Equivalents Outstanding (as
                        hereinafter defined) immediately prior to such issue or
                        sale of Additional Shares of Common Stock plus (B) the
                        quotient obtained by dividing the Aggregate
                        Consideration Received (as hereinafter defined) by the
                        Corporation for the total number of Additional Shares of
                        Common Stock so issued or sold (or deemed so issued and
                        sold) by the Conversion Price for such series of
                        Preferred Stock in effect immediately prior to such
                        issue or sale; and

                (ii)    The denominator of which shall be the sum of (A) the
                        number of Common Stock Equivalents Outstanding
                        immediately prior to such issue or sale of Additional
                        Shares of Common Stock plus (B) the number of Additional
                        Shares of Common Stock so issued or sold (or deemed so
                        issued and sold).

                      (b) Certain Definitions. For the purpose of making any
adjustment required under this subsection 5.7:

                           (i) "Additional Shares of Common Stock" shall mean
all shares of Common Stock issued by the Corporation, whether or not
subsequently reacquired or retired by the Corporation, other than: (A) shares of
Common Stock issued or issuable upon conversion of Preferred Stock; and (B)
shares of Common Stock (or options, warrants or rights therefor) issued to
employees, officers or directors of, or contractors, consultants or advisers to,
the Corporation or any Subsidiary pursuant to stock purchase or stock option
plans, stock bonuses or awards, warrants, contracts or other arrangements that
are approved by the Board; and (C) up to 36,764 shares of Preferred Stock (or
warrants therefor) issued by the Corporation to lenders in connection with loan
financing transactions and any other shares of Preferred Stock or Common Stock
(or warrants therefor) that are unanimously approved by the Board for issuance
to lenders or equipment lessors;

                           (ii) The "Aggregate Consideration Received" by the
Corporation for any issue or sale (or deemed issue or sale) of securities shall
(A) to the extent it consists of cash, be computed at the gross amount of cash
received by the Corporation before deduction of any underwriting or similar
commissions, compensation or concessions paid or allowed by the Corporation in
connection with such issue or sale and without deduction of any expenses payable
by the Corporation; (B) to the extent it consists of property other than cash,
be computed at the fair value of that property as determined in good faith by
the Board; and (C) if Additional Shares of Common Stock, Convertible Securities
or Rights or Options to purchase either Additional Shares of Common Stock or
Convertible Securities are issued or sold together with other stock or
securities or other assets of the Corporation for a consideration which covers
both, be computed as the portion of the consideration so received that may be
reasonably determined in good faith by the Board to be allocable to such
Additional Shares of Common Stock, Convertible Securities or Rights or Options;

                           (iii) "Common Stock Equivalents Outstanding" shall
mean the number of shares of Common Stock that is equal to the sum of (A) all
shares of Common Stock of the Corporation that are outstanding at the time in
question, plus (B) all shares of Common Stock of the Corporation issuable upon
conversion of all shares of Preferred Stock or other Convertible Securities that
are outstanding at the time in question, plus (C) all shares of Common Stock of
the Corporation that are issuable upon the exercise of Rights or Options that
are outstanding at the time in question assuming the full conversion or exchange
into Common Stock of all such Rights or Options that are Rights or Options to
purchase or acquire Convertible Securities into or for Common Stock;

                           (iv) "Convertible Securities" shall mean stock or
other securities convertible into or exchangeable for shares of Common Stock or
for shares of Preferred Stock that are convertible into shares of Common Stock;

                           (v) The "Effective Price" of Additional Shares of
Common Stock shall mean the quotient determined by dividing the total number of
Additional Shares of Common Stock issued or sold, or deemed to have been issued
or sold, by the Corporation under this subsection 5.7, into the Aggregate
Consideration Received, or deemed to have been received, by the Corporation
under this subsection 5.7, for the issue of such Additional Shares of Common
Stock; and

                           (vi) "Rights or Options" shall mean warrants, options
or other rights to purchase or acquire shares of Common Stock or Convertible
Securities.

                      (c) Deemed Issuances. For the purpose of making any
adjustment to the Conversion Price of the Preferred Stock required under this
subsection 5.7, if the Corporation issues or sells any Rights or Options or
Convertible Securities and if the Effective Price of the shares of Common Stock
issuable upon exercise of such Rights or Options and/or the conversion or
exchange of Convertible Securities (computed without reference to any additional
or similar protective or antidilution clauses) is less than the Conversion Price
then in effect for a series of Preferred Stock, then the Corporation shall be
deemed to have issued, at the time of the issuance of such Rights, Options or
Convertible Securities, that number of Additional Shares of Common Stock that is
equal to the maximum number of shares of Common Stock issuable upon exercise or
conversion of such Rights, Options or Convertible Securities upon their issuance
and to have received, as the Aggregate Consideration Received for the issuance
of such shares, an amount equal to the total amount of the consideration, if
any, received by the Corporation for the issuance of such Rights or Options or
Convertible Securities, plus, in the case of such Rights or Options, the minimum
amounts of consideration, if any, payable to the Corporation upon the exercise
in full of such Rights or Options, plus, in the case of Convertible Securities,
the minimum amounts of consideration, if any, payable to the Corporation (other
than by cancellation of liabilities or obligations evidenced by such Convertible
Securities) upon the conversion or exchange thereof; provided that:

                           (i) if the minimum amounts of such consideration
cannot be ascertained, but are a function of antidilution or similar protective
clauses, then the Corporation

                                                      Certificate of Designation

shall be deemed to have received the minimum amounts of consideration without
reference to such clauses;

                           (ii) if the minimum amount of consideration payable
to the Corporation upon the exercise of Rights or Options or the conversion or
exchange of Convertible Securities is reduced over time or upon the occurrence
or non-occurrence of specified events other than by reason of antidilution or
similar protective adjustments, then the Effective Price shall be recalculated
using the figure to which such minimum amount of consideration is reduced; and

                           (iii) if the minimum amount of consideration payable
to the Corporation upon the exercise of such Rights or Options or the conversion
or exchange of Convertible Securities is subsequently increased, then the
Effective Price shall again be recalculated using the increased minimum amount
of consideration payable to the Corporation upon the exercise of such Rights or
Options or the conversion or exchange of such Convertible Securities.

No further adjustment of the Conversion Price, adjusted upon the issuance of
such Rights or Options or Convertible Securities, shall be made as a result of
the actual issuance of shares of Common Stock or Preferred Stock on the exercise
of any such Rights or Options or the conversion or exchange of any such
Convertible Securities. If any such Rights or Options or the conversion rights
represented by any such Convertible Securities shall expire without having been
fully exercised, then the Conversion Price as adjusted upon the issuance of such
Rights or Options or Convertible Securities shall be readjusted to the
Conversion Price which would have been in effect had an adjustment been made on
the basis that the only shares of Common Stock so issued were the shares of
Common Stock, if any, that were actually issued or sold on the exercise of such
Rights or Options or rights of conversion or exchange of such Convertible
Securities, and such shares of Common Stock, if any, were issued or sold for the
consideration actually received by the Corporation upon such exercise, plus the
consideration, if any, actually received by the Corporation for the granting of
all such Rights or Options, whether or not exercised, plus the consideration
received for issuing or selling all such Convertible Securities actually
converted or exchanged, plus the consideration, if any, actually received by the
Corporation (other than by cancellation of liabilities or obligations evidenced
by such Convertible Securities) on the conversion or exchange of such
Convertible Securities, provided that such readjustment shall not apply to prior
conversions of Preferred Stock.

        5.8 Certificate of Adjustment. In each case of an adjustment or
readjustment of the Conversion Price for a series of Preferred Stock, the
Corporation, at its expense, shall cause its Chief Financial Officer to compute
such adjustment or readjustment in accordance with the provisions hereof and
prepare a certificate showing such adjustment or readjustment, and shall mail
such certificate, by first class mail, postage prepaid, to each registered
holder of the Preferred Stock at the holder's address as shown in the
Corporation's books.

        5.9 Fractional Shares. No fractional shares of Common Stock shall be
issued upon any conversion of Preferred Stock. In lieu of any fractional share
to which the holder would otherwise be entitled, the Corporation shall pay the
holder cash equal to the product of

such fraction multiplied by the Common Stock's fair market value as determined
in good faith by the Board as of the date of conversion.

               5.10 Reservation of Stock Issuable Upon Conversion. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Preferred Stock, such number of its shares of
Common Stock as shall from time to time be sufficient to effect the conversion
of all outstanding shares of the Preferred Stock; and if at any time the number
of authorized but unissued shares of Common Stock shall not be sufficient to
effect the conversion of all then outstanding shares of the Preferred Stock, the
Corporation will take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purpose.

               5.11 Notices. Any notice required by the provisions of this
Section 5 to be given to the holders of shares of the Preferred Stock shall be
deemed given upon the earlier of actual receipt or deposit in the United States
mail, by certified or registered mail, return receipt requested, postage
prepaid, addressed to each holder of record at the address of such holder
appearing on the books of the Corporation.

               5.12 No Impairment. The Corporation shall not avoid or seek to
avoid the observance or performance of any of the terms to be observed or
performed hereunder by the Corporation, but shall at all times in good faith
assist in carrying out all such action as may be reasonably necessary or
appropriate in order to protect the conversion rights of the holders of the
Preferred Stock against impairment.

such Rights Holder's election to exercise its Right of First Offer (an
"Election") for a specified number of IPO Shares up to a maximum equal to the
Maximum IPO Shares Number (the "Requested IPO Shares Number"), which Requested
IPO Shares Number shall be subject to reduction in accordance with the terms and
conditions of this Agreement. Each Election shall be deemed to be made in
anticipation of (I) the Offering Price being in a range, the lower end of which

of the Offering Price Range by 150% (the "Final Offering Price Range") and (II)
the IPO Shares Number being in a range, the lower end of which is no lower than
the product that results from multiplying the Estimated IPO Shares Number by 80%
and the


                                       3

<PAGE>   4

upper end of which is no higher than the product that results from multiplying
the Estimated IPO Shares Number by 150% (the "Final IPO Shares Number Range").
In the Election, the Rights Holder shall also set forth the name, telephone
number, facsimile number and pager number for those person(s) authorized by it
to make a revocation decision in accordance with the terms of subsection (e),
below, and to make a confirmation decision in accordance with the terms of
subsection (f), below.

               (b)  Elections for Maximum IPO Shares Number or Less. If the sum
of all of the Requested IPO Shares Numbers of the Rights Holders is equal to or
less than the Maximum IPO Shares Number, then each Rights Holder will be deemed
have exercised its Right of First Offer for its respective Requested IPO Shares
Number.

               (c)  Elections for More than Maximum IPO Shares Number. If the
sum of all of the Requested IPO Shares Numbers of the Rights Holders is greater
than the Maximum IPO Shares Number, then each Rights Holder will be deemed to
have exercised its Right of First Offer for a number of IPO Shares that is
determined as follows:

                    (1)  Each Rights Holder shall be deemed to have exercised
its Right of First Offer for the lesser of (I) such Rights Holder's Requested
IPO Shares Number and (II) such Rights Holder's Pro Rata Share of the Maximum
IPO Shares Number.

                    (2)  If the foregoing deemed exercises of the Rights of
First Offer of all of the Rights Holders pursuant to clause (c)(1) are for an
aggregate number of IPO Shares that is less than the Maximum IPO Shares Number,
then the remaining number of IPO Shares shall be deemed subject to further
exercises of the Right of First Offer by each Rights Holder whose Requested IPO
Shares Number was equal to or greater than its Pro Rata Share of the Maximum IPO
Shares Number (each a "Continuing Rights Holder") for an additional number of
IPO Shares equal to the lesser of (I) a number of IPO Shares equal to the number
that results from subtracting (x) the aggregate number of IPO Shares as to which
such Continuing Rights Holder was deemed to have exercised its Right of First
Offer in accordance with the preceding provisions of this subsection (c) from
(y) such Rights Holder's Requested IPO Shares Number and (II) such Continuing
Rights Holder's "Subsequent Pro Rata Share" of such remaining number of IPO
Shares. For purposes of this subsection (c)(2), a Continuing Rights Holder's
"Subsequent Pro Rata Share" means the quotient that results from dividing (aa)
the total number of Series E Equivalent Shares that such Continuing Rights
Holder held on the Record Date by (bb) the total number of Series E Equivalent
Shares that all Continuing Rights Holders held on the Record Date.

                    (3)  If the deemed exercises of the Rights of First Offer of
all of the Rights Holders pursuant to each of the foregoing clauses of this
subsection (c) are, in the aggregate, for a total number of IPO Shares that is
less than the Maximum IPO Shares Number, then the number of IPO Shares that
still remains shall be deemed subject to yet further exercises of the Right of
First Offer by each Continuing Rights Holder who, as a result of its aggregate
deemed exercises in each of the foregoing clauses of this subsection (c), is not
yet deemed to have elected, in the aggregate, to be offered a number IPO Shares
equal to its Requested IPO Shares Number, for additional numbers of IPO Shares
determined in accordance with the same


                                       4

<PAGE>   5

provisions as are set forth in subsection (c)(2) above, except that a
"Continuing Rights Holder" shall instead mean and refer to a Rights Holder who
is deemed to have a continuing Right of First Offer under this subsection
(c)(3), the remaining number of IPO Shares shall instead mean and refer to the
number of IPO Shares remaining from the Maximum IPO Shares Number after taking
into account all of the preceding deemed exercises of the Rights of First Offer,
and the "Subsequent Pro Rata Share" shall instead be calculated with reference a
denominator including shares owned only by those Continuing Rights Holders who
are deemed to have a continuing Right of First Offer under this subsection
(c)(3). The provisions of this subsection (c)(3) shall continue to be applied in
successive rounds until the first to occur of (A) the aggregate number of IPO
Shares as to which deemed exercises of the Rights of First Offer under this
subsection (c) have been made equals the Maximum IPO Shares Number or (B) each
of the Rights Holders has, by virtue of the deemed exercises of its Right of
First Offer under this subsection (c), exercised its Right of First Offer for a
number of IPO Shares equal to its Requested IPO Shares Number.

               (d)  Final Notice and Offer in IPO. A Rights Holder's exercise of
the Right of First Offer in accordance with subsection (b) or (c) hereof, as
applicable, shall be deemed an expression of interest in receiving an offer by
the Company to purchase that number of IPO Shares. The Company's offer to sell
such IPO Shares to the Rights Holders shall be deemed to occur automatically
upon the completion of the latest to occur of (i) the earliest to occur of (A)
the conclusion of any live, person-to-person communication (whether in-person or
by telephone) between a representative of the Company or the managing
underwriter and a representative of the Rights Holder designated by the Rights
Holder in its Election in which the Company or the managing underwriter notifies
the Rights Holder of the Offering Price and the IPO Shares Number; or (B) four
(4) hours after notice is given by the Company or the managing underwriter to a
representative of the Rights Holder designated by the Rights Holder in its
Election (with a contemporaneous copy to the Rights Holder's designated counsel
identified in Section 4.1(a) below) by actual delivery or facsimile transmission
of the Offering Price and the IPO Shares Number (such notice under either of
clauses (i)(A) or (i)(B) hereafter referred to as a "Final Notice"); and (ii)
the effectiveness of the Registration Statement (the completion of the later to
occur of the foregoing hereof, the "Offer Time"). In the event that the
Registration Statement becomes effective prior to the Company or the managing
underwriter giving a Final Notice to the representative of a Rights Holder as
provided for in clause (ii) of the immediately preceding sentence, the Company
or the managing underwriting shall give such Final Notice as promptly as
reasonably practicable and such Rights Holder's Right of First Offer shall not
be deemed to be inapplicable to the IPO by virtue of any failure to give such
Final Notice.

               (e)  IPO Within Ranges. Upon the giving of Final Notice by the
Company or the managing underwriter to the Rights Holder (with a contemporaneous
copy to the Rights Holder's designated counsel identified in Section 4.1(a)
below in the case of actual delivery or delivery by facsimile transmission) in
accordance with the provisions of subsection (d), if both (i) the Offering Price
described in the Final Notice is within the Final Offering Price Range and (ii)
the IPO Shares Number described in the Final Notice is within the Final IPO
Shares Number Range, then each Rights Holder who delivered an Election shall
have an unconditional right to terminate its Right of First Offer and revoke its
exercise thereof (x) by delivering oral notice thereof in any communication
described in clause (i)(A) of subsection (d), or (y) by delivering written
notice thereof by facsimile transmission, or by actual receipt, in each


                                       5

<PAGE>   6

such case prior to or at the Offer Time. Once timely revoked by a Rights Holder,
the Right of First Offer as to such Rights Holder shall become null and void. A
Rights Holder's exercise of the Right of First Offer shall, unless so revoked by
such Rights Holder on or before the Offer Time, automatically be deemed,
immediately after the Offer Time, to be a binding commitment to purchase the
number of IPO Shares as to which such Rights Holder is deemed to have exercised
its Right of First Offer hereunder at the Offering Price for each such IPO
Share.

               (f)  IPO Outside of Ranges. Upon the giving of Final Notice by
the Company or the managing underwriter to the Rights Holder (with a
contemporaneous copy to the Rights Holder's designated counsel identified in
Section 4.1(a) below in the case of actual delivery or delivery by facsimile
transmission) in accordance with the provisions of subsection (d), if either (i)
the Offering Price described in the Final Notice is outside of the Final
Offering Price Range or (ii) the IPO Shares Number described in the Final Notice
is outside the Final IPO Shares Number Range, then each Rights Holder who
delivered an Election shall have until prior to or at the Offer Time to confirm
its Election hereunder (a "Confirmation") (notwithstanding the fact that the
Offering Price is not within the Final Offering Price Range or that the IPO
Shares Number is not within the Final IPO Shares Number Range) (x) by delivering
oral notice thereof in any communication described in clause (i)(A) of
subsection (d), or (y) by delivering written notice thereof by facsimile
transmission, or by actual receipt. Any Rights Holder who fails to so confirm
its Election in accordance with the foregoing shall be automatically deemed to
have revoked its Election and its Right of First Offer shall become null and
void. Each Rights Holder who delivered an Election shall have an unconditional
right to so revoke its Election and its Right of First Offer. A Rights Holder's
timely delivery of a Confirmation in accordance with the terms and conditions
hereof shall be a binding commitment to purchase the number of IPO Shares as to
which such Rights Holder is deemed to have exercised its Right of First Offer
hereunder at the Offering Price for each such IPO Share.

               (g)  Closing and Restrictions. The Rights Holders' purchases of
IPO Shares in accordance with this Section 1 shall occur simultaneously with the
Closing. The IPO Shares purchased by any Rights Holder pursuant to this Section
1 shall be subject to any restrictions on resale imposed by rules or regulations
of the SEC, the NASD, the Nasdaq Stock Market, Inc., or other regulatory body.

          1.4  Termination of Right of First Refusal. Each Rights Holder's Right
of First Offer terminates immediately after the Closing.

          1.5  This Agreement Not an Offer. This Agreement does not constitute
an offer to sell securities of the Company. Any offering of shares of the
Company's Common Stock in the IPO will only be made pursuant to a prospectus
filed with the SEC.

     2.   BOARD OBSERVER RIGHTS.

          2.1  Observer Rights. The Company will permit one (1) representative
of the Investors (as designated in a writing delivered to the Company from time
to time that is executed by those Investors then holding a majority of the
Series E Equivalent Shares) (the "Representative") to attend all meetings of the
Company's Board of Directors in a non-voting observer capacity. The Company will
also provide the Representative with copies of all notices,


                                       6

<PAGE>   7

minutes and other materials that it provides to its directors with respect to
such meetings ("Board Materials"). The initial Representative shall be Harvey
Allison.

          2.2  Restrictions.

               (a)  Prior to attending any meeting or receiving any written
materials pursuant to Section 2.1, the Representative shall execute and deliver
to the Company an agreement providing that, except to the extent otherwise
required by law, the Representative shall hold in strict confidence, and not
disclose to any party other than to another Investor who has executed this
Agreement, all information and materials the Representative received pursuant to
Section 2.1; provided, however, that the Representative may disclose such
information and materials on a confidential basis to the professional advisors
or employees of an Investor who are under a duty to hold such information and
materials in confidence to the extent reasonably necessary for such Investor to
monitor its investment in the Company.

               (b)  Except to the extent otherwise required by law, each
Investor shall hold in strict confidence, and not disclose to any party, all
information and materials received from the Representative that the
Representative received pursuant to Section 2.1; provided, however, that the
Investor may disclose such information and materials on a confidential basis to
its professional advisors or employees who are under a duty to hold such
information and materials in confidence to the extent reasonably necessary for
such Investor to monitor its investment in the Company.

               (c)  The Representative may be excluded from certain confidential
"closed sessions" of the Board at any portions of a Board meeting if (i) the
presence of the Representative would jeopardize the Company's attorney-client
privilege or (ii) if the Board otherwise reasonably so requires; provided,
however, that the Board may not so exclude the Representative pursuant to clause
(ii) of this sentence with respect to matters of corporate governance. In
addition, the Company may withhold from the Representative any portions of any
Board Materials (i) if the disclosure of such portions of Board Materials would
jeopardize the Company's attorney-client privilege or (ii) if the Board
otherwise reasonably so requires; provided, however, that the Board may not so
exclude the Representative pursuant to clause (ii) of this sentence with respect
to matters of corporate governance.

          2.3  Termination.

               The rights of the Investors under Section 2 of this Agreement
shall terminate upon the first to occur of: (a) the date on which the Investors
hold, in the aggregate, fewer than 245,000 shares of any combination of Series E
Equivalent Shares, (b) the closing of an IPO; (c) the sale of all or
substantially all the Company's assets; or (d) upon the closing of any merger or
other acquisition involving the Company in which the Company is not the
surviving corporation or in which the shareholders of the Company immediately
prior to such merger or acquisition own less than fifty percent (50%) of the
voting equity securities of the surviving corporation or entity immediately
after such merger or acquisition.

     3.   ASSIGNMENT AND AMENDMENT.

          3.1  Assignment. The rights an Investor under Sections 1 and 2 hereof
may be assigned in connection with any transfer of shares of Series E Stock or
shares of Conversion Stock in accordance with the applicable provisions of
Section 4.7 of the Series E Agreement (i) by an Investor that is a partnership,
corporation or limited liability company to (A) a partner of such partnership, a

Company's Articles of Incorporation), or (iv) by any Investor that is a
corporation, partnership or limited liability company to an affiliate.

party at the time of such assignment stating the name and address of the
assignee and identifying the securities of the Company as to which the rights in
question are being assigned and (ii) any such assignee agrees in a writing
delivered to the Company to receive such assigned rights subject to all the

                       BROADBASE INFORMATION SYSTEMS, INC.

                           1996 EQUITY INCENTIVE PLAN

               As adopted March 4, 1996 and amended June 28, 1999


         1. PURPOSE. The purpose of the Plan is to provide incentives to
attract, retain and motivate eligible persons whose present and potential
contributions are important to the success of the Company, its Parent,
Subsidiaries and Affiliates, by offering them an opportunity to participate in
the Company's future performance through awards of Options and Restricted Stock.
Capitalized terms not defined in the text are defined in Section 22. This Plan
is intended to be a written compensatory benefit plan within the meaning of Rule
701 promulgated under the Securities Act.

         2. SHARES SUBJECT TO THE PLAN.

            2.1 Number of Shares Available. Subject to Sections 2.2 and 17, the
total number of Shares reserved and available for grant and issuance pursuant to
the Plan shall be 4,530,000 Shares as permitted under Section 260.140.45 of
Title 10 of the California Code of Regulations.(1) Subject to Sections 2.2 and
17 hereto, Shares subject to Awards previously granted shall again be available
for grant and issuance in connection with future Awards under the Plan that: (a)
are subject to issuance upon exercise of an Option but cease to be subject to
such Option for any reason other than exercise of such Option, (b) are subject
to an Award granted hereunder but are forfeited or are repurchased by the
Company at the original issue price, or (c) are subject to an Award that
otherwise terminates without Shares being issued. At all times the Company will
reserve and keep available a sufficient number of Shares as will be required to
satisfy the requirements of all Awards granted and outstanding under the Plan.

            2.2 Adjustment of Shares. In the event that the number of
outstanding shares of the Company's Common Stock is changed by a stock dividend,
recapitalization, stock split, reverse stock split, subdivision, combination,
reclassification or similar change in the capital structure of the Company
without consideration, then (a) the number of Shares reserved for issuance under
the Plan, (b) the Exercise Prices of and number of Shares subject to outstanding
Options, and (c) the Purchase Price of and number of Shares subject to other
outstanding Awards shall be proportionately adjusted, subject to any required
action by the Board or the shareholders of the Company and compliance with
applicable securities laws; provided, however, that fractions of a Share shall
not be issued but shall either be paid in cash at Fair Market Value of such
fraction of a Share or shall be rounded up to the nearest whole Share, as
determined by the Committee.

         3. ELIGIBILITY. ISOs (as defined in Section 5 below) may be granted
only to employees (including officers and directors who are also employees) of
the Company or of a Parent or Subsidiary of the Company. All other Awards may be
granted to employees, officers,

directors, consultants and advisers of the Company or any Parent, Subsidiary or
Affiliate of the Company; provided such consultants and advisers render bona
fide services not in connection with the offer and sale of securities in a
capital-raising transaction. A person may be granted more than one Award under
the Plan.

         4. ADMINISTRATION.

            4.1 Committee Authority. The Plan shall be administered by the
Committee or the Board if no Committee has been created by the Board. Subject to
the general purposes, terms and conditions of the Plan, and to the direction of
the Board, the Committee shall have full power to implement and carry out the
Plan. Without limitation, the Committee shall have the authority to:

                (a) construe and interpret the Plan, any Award Agreement and any
                    other agreement or document executed pursuant to the Plan;

                (b) prescribe, amend and rescind rules and regulations relating
                    to the Plan;

                (c) select persons to receive Awards;

                (d) determine the form and terms of Awards;

                (e) determine the number of Shares or other consideration
                    subject to Awards;

                (f) determine whether Awards will be granted singly, in
                    combination with, in tandem with, in replacement of, or as
                    alternatives to, other Awards under the Plan or awards under
                    any other incentive or compensation plan of the Company or
                    any Parent, Subsidiary or Affiliate of the Company;

                (g) grant waivers of any conditions of this Plan or any Award
                    conditions;

                (h) determine the vesting, exercisability and payment of Awards;

                (i) correct any defect, supply any omission, or reconcile any
                    inconsistency in the Plan, any Award or any Award Agreement;

                (j) determine whether an Award has been earned; and

                (k) make all other determinations necessary or advisable for the
                    administration of the Plan.

            4.2 Committee Discretion. Any determination made by the Committee
with respect to any Award shall be made in its sole discretion either (i) at the
time of grant of the


                                      -2-
<PAGE>   3

Award or (ii) subject to Section 5.9 hereof, unless in contravention of any
express term of the Plan or Award, at any later time, and such determination
shall be final and binding on the Company and all persons having an interest in
any Award under the Plan. The Committee may delegate to one or more officers of
the Company the authority to grant an Award under the Plan, provided such
officer or officers are members of the Board.

         5. OPTIONS. The Committee may grant Options to eligible persons and
shall determine whether such Options shall be Incentive Stock Options within the
meaning of the Code ("ISOs") or Nonqualified Stock Options ("NQSOs"), the number
of Shares subject to the Option, the Exercise Price of the Option, the period
during which the Option may be exercised, and all other terms and conditions of
the Option, subject to the following:

            5.1 Form of Option Grant. Each Option granted under the Plan shall
be evidenced by an Award Agreement which shall expressly identify the Option as
an ISO or NQSO ("Stock Option Agreement"), and be in such form and contain such
provisions (which need not be the same for each Participant) as the Committee
shall from time to time approve, and which shall comply with and be subject to
the terms and conditions of the Plan.

            5.2 Date of Grant. The date of grant of an Option shall be the date
on which the Committee makes the determination to grant such Option, unless a
later date is otherwise specified by the Committee. The Stock Option Agreement
and a copy of the Plan will be delivered to the Participant within a reasonable
time after the granting of the Option.

            5.3 Exercise Period. Options may be exercisable immediately (subject
to repurchase pursuant to Section 11 of the Plan) or may be exercisable within
the times or upon the events determined by the Committee as set forth in the
Stock Option Agreement governing such Option; provided, however, that no Option
shall be exercisable after the expiration of ten (10) years from the date the
Option is granted, and provided further that no ISO granted to a person who
directly or by attribution owns more than ten percent (10%) of the total
combined voting power of all classes of stock of the Company or any Parent or
Subsidiary of the Company ("Ten Percent Shareholder") shall be exercisable after
the expiration of five (5) years from the date the ISO is granted. The Committee
also may provide for the exercise of Options to become exercisable at one time
or from time to time, periodically or otherwise, in such number of Shares or
percentage of Shares as the Committee determines. Subject to earlier termination
of the Option as provided herein, each Participant who is not an officer,
director or consultant of the Company or of a Parent or Subsidiary of the
Company shall have the right to exercise an Option granted hereunder at the rate
of no less than twenty percent (20%) per year over five (5) years from the date
such Option is granted.

            5.4 Exercise Price. The Exercise Price of an Option shall be
determined by the Committee when the Option is granted and may be not less than
85% of the Fair Market Value of the Shares on the date of grant; provided that
(i) the Exercise Price of an ISO shall be not less than 100% of the Fair Market
Value of the Shares on the date of grant and (ii) the Exercise Price of any
Option granted to a Ten Percent Shareholder shall not be less than 110% of the
Fair Market Value of the Shares on the date of grant. Payment for the Shares
purchased may be made in accordance with Section 7 of the Plan.


                                      -3-
<PAGE>   4

            5.5 Method of Exercise. Options may be exercised only by delivery to
the Company of a written stock option exercise agreement (the "Exercise
Agreement") in a form approved by the Committee (which need not be the same for
each Participant), stating the number of Shares being purchased, the
restrictions imposed on the Shares purchased under such Exercise Agreement, if
any, and such representations and agreements regarding Participant's investment
intent and access to information and other matters, if any, as may be required
or desirable by the Company, and any applicable taxes, to comply with applicable
securities laws, together with payment in full of the Exercise Price, and any
applicable taxes, for the number of Shares being purchased.

            5.6 Termination. Subject to earlier termination pursuant to Sections
16 or 17 and notwithstanding the exercise periods set forth in the Stock Option
Agreement, exercise of an Option shall always be subject to the following:

                (a) If the Participant is Terminated for any reason except
                    death, Disability, or for Cause, then Participant may
                    exercise such Participant's Options only to the extent that
                    such Options are exercisable upon the Termination Date. Such
                    Options must be exercised by the Participant, if at all, as
                    to all or some of the Vested Shares calculated as of the
                    Termination Date, within three (3) months after the
                    Termination Date (or within such shorter time period, not
                    less than thirty (30) days, or within such longer time
                    period, after the Termination Date as may be determined by
                    the Committee, with any exercise beyond three (3) months
                    after the Termination Date deemed to be an NQSO), but in any
                    event, no later than the expiration date of the Options.

                (b) If the Participant is Terminated because of Participant's
                    death or Disability (or the Participant dies within three
                    (3) months after a Termination other than for Cause), then
                    Participant's Options may be exercised only to the extent
                    that such Options are exercisable by Participant on the
                    Termination Date. Such Options must be exercised by
                    Participant (or Participant's legal representative or
                    authorized assignee) if at all, as to all or some of the
                    Vested Shares calculated as of the Termination Date, within
                    twelve (12) months after the Termination Date (or within
                    such shorter time period, not less than six (6) months, or
                    within such longer time period, after the Termination Date
                    as may be determined by the Committee, with any exercise
                    beyond (i) three (3) months after the Termination Date when
                    the Termination is for any reason other than the
                    Participant's death or disability, within the meaning of
                    Section 22(e)(3) of the Code, or (ii) twelve (12) months
                    after the Termination Date when the Termination is for
                    Participant's disability, within the meaning of Section
                    22(e)(3) of the Code, deemed to be an NQSO), but in any
                    event no later than the expiration date of the Options.


                                      -4-
<PAGE>   5

                (c) If the Participant is Terminated for Cause, then
                    Participant's Options shall expire on such Participant's
                    Termination Date, or at such later time and on such
                    conditions as determined by the Committee.

            5.7 Limitations on Exercise. The Committee may specify a reasonable
minimum number of Shares that may be purchased on any exercise of an Option,
provided that such minimum number will not prevent Participant from exercising
the Option for the full number of Shares for which it is then exercisable.

            5.8 Limitations on ISOs. The aggregate Fair Market Value (determined
as of the date of grant) of Shares with respect to which ISOs are exercisable
for the first time by a Participant during any calendar year (under the Plan or
under any other incentive stock option plan of the Company or any Affiliate,
Parent or Subsidiary of the Company) shall not exceed $100,000. If the Fair
Market Value of Shares on the date of grant with respect to which ISOs are
exercisable for the first time by a Participant during any calendar year exceeds
$100,000, the Options for the first $100,000 worth of Shares to become
exercisable in such calendar year shall be ISOs and the Options for the amount
in excess of $100,000 that become exercisable in that calendar year shall be
NQSOs. In the event that the Code or the regulations promulgated thereunder are
amended after the Effective Date of the Plan to provide for a different limit on
the Fair Market Value of Shares permitted to be subject to ISOs, such different
limit shall be automatically incorporated herein and shall apply to any Options
granted after the effective date of such amendment.

            5.9 Modification, Extension or Renewal. The Committee may modify,
extend or renew outstanding Options and authorize the grant of new Options in
substitution therefor, provided that any such action may not, without the
written consent of Participant, impair any of Participant's rights under any
Option previously granted. Any outstanding ISO that is modified, extended,
renewed or otherwise altered shall be treated in accordance with Section 424(h)
of the Code. Subject to Section 5.10 hereof, the Committee may reduce the
Exercise Price of outstanding Options without the consent of Participants
affected by a written notice to them; provided, however, that the Exercise Price
may not be reduced below the minimum Exercise Price that would be permitted
under Section 5.4 of the Plan for Options granted on the date the action is
taken to reduce the Exercise Price.

            5.10 No Disqualification. Notwithstanding any other provision in the
Plan, no term of the Plan relating to ISOs shall be interpreted, amended or
altered, nor shall any discretion or authority granted under the Plan be
exercised, so as to disqualify the Plan under Section 422 of the Code or,
without the consent of the Participant affected, to disqualify any ISO under
Section 422 of the Code.

         6. RESTRICTED STOCK. A Restricted Stock Award is an offer by the
Company to sell to an eligible person Shares that are subject to restrictions.
The Committee shall determine to whom an offer will be made, the number of
Shares the person may purchase, the Purchase Price, the restrictions to which
the Shares shall be subject, and all other terms and conditions of the
Restricted Stock Award, subject to the following:


                                      -5-
<PAGE>   6

            6.1 Form of Restricted Stock Award. All purchases under a Restricted
Stock Award made pursuant to the Plan shall be evidenced by an Award Agreement
("Restricted Stock Purchase Agreement") that shall be in such form (which need
not be the same for each Participant) as the Committee shall from time to time
approve, and shall comply with and be subject to the terms and conditions of the
Plan. The offer of Restricted Stock shall be accepted by the Participant's
execution and delivery of the Restricted Stock Purchase Agreement and full
payment for the Shares to the Company within thirty (30) days from the date the
Restricted Stock Purchase Agreement is delivered to the person. If such person
does not execute and deliver the Restricted Stock Purchase Agreement along with
full payment for the Shares to the Company within thirty (30) days, then the
offer shall terminate, unless otherwise determined by the Committee.

            6.2 Purchase Price. The Purchase Price of Shares sold pursuant to a
Restricted Stock Award shall be determined by the Committee and shall be at
least 85% of the Fair Market Value of the Shares on the date the Restricted
Stock Award is granted or at the time the purchase is consummated, except in the
case of a sale to a Ten Percent Shareholder, in which case the Purchase Price
shall be 100% of the Fair Market Value on the date the Restricted Stock Award is
granted or at the time the purchase is consummated. Payment of the Purchase
Price may be made in accordance with Section 7 of the Plan.

            6.3 Restrictions. Restricted Stock Awards may be subject to the
restrictions set forth in Section 11 hereof or such other restrictions not
inconsistent under Section 25102(o) of the California Corporations Code.

         7. PAYMENT FOR SHARE PURCHASES.

            7.1 Payment. Payment for Shares purchased pursuant to the Plan may
be made in cash (by check) or, where expressly approved for the Participant by
the Committee and where permitted by law:

                (a) by cancellation of indebtedness of the Company to the
                    Participant;

                (b) by surrender of shares of the Company's capital stock that
                    either: (1) have been owned by Participant for more than six
                    (6) months and have been paid for within the meaning of SEC
                    Rule 144 (and, if such shares were purchased from the
                    Company by use of a promissory note, such note has been
                    fully paid with respect to such shares); or (2) were
                    obtained by Participant in the public market;

                (c) by tender of a full recourse promissory note having such
                    terms as may be approved by the Committee and bearing
                    interest at a rate sufficient to avoid imputation of income
                    under Sections 483 and 1274 of the Code; provided, however,
                    that Participants who are not employees or directors of the
                    Company shall not be entitled to purchase Shares with a
                    promissory note unless the note is adequately secured by
                    collateral other than the Shares;


                                      -6-
<PAGE>   7

                (d) by waiver of compensation due or accrued to Participant for
                    services rendered;

                (e) with respect only to purchases upon exercise of an Option,
                    and provided that a public market for the Company's stock
                    exists:

                    (1) through a "same day sale" commitment from Participant
                        and a broker-dealer that is a member of the National
                        Association of Securities Dealers (an "NASD Dealer")
                        whereby the Participant irrevocably elects to exercise
                        the Option and to sell a portion of the Shares so
                        purchased to pay for the Exercise Price, and whereby the
                        NASD Dealer irrevocably commits upon receipt of such
                        Shares to forward the Exercise Price directly to the
                        Company; or

                    (2) through a "margin" commitment from Participant and an
                        NASD Dealer whereby Participant irrevocably elects to
                        exercise the Option and to pledge the Shares so
                        purchased to the NASD Dealer in a margin account as
                        security for a loan from the NASD Dealer in the amount
                        of the Exercise Price, and whereby the NASD Dealer
                        irrevocably commits upon receipt of such Shares to
                        forward the Exercise Price directly to the Company; or

                (f) by any combination of the foregoing.

            7.2 Loan Guarantees. The Committee may help the Participant pay for
Shares purchased under the Plan by authorizing a guarantee by the Company of a
third-party loan to the Participant.

         8. WITHHOLDING TAXES.

            8.1 Withholding Generally. Whenever Shares are to be issued in
satisfaction of Awards granted under the Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares. Whenever, under the Plan, payments
in satisfaction of Awards are to be made in cash by the Company, such payment
shall be net of an amount sufficient to satisfy federal, state, and local
withholding tax requirements.

            8.2 Stock Withholding. When, under applicable tax laws, a
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined (the "Tax Date"). All elections by a Participant to
have Shares withheld for this purpose shall be


                                      -7-
<PAGE>   8

made in writing in a form acceptable to the Committee and shall be subject to
the following restrictions:

                (a) the election must be made on or prior to the applicable Tax
                    Date;

                (b) once made, then except as provided below, the election shall
                    be irrevocable as to the particular Shares as to which the
                    election is made;

                (c) all elections shall be subject to the consent or disapproval
                    of the Committee; and

                (d) in the event that the Tax Date is deferred until six (6)
                    months after the delivery of Shares under Section 83(b) of
                    the Code, the Participant shall receive the full number of
                    Shares with respect to which the exercise occurs, but such
                    Participant shall be unconditionally obligated to tender
                    back to the Company the proper number of Shares on the Tax
                    Date.

         9. PRIVILEGES OF STOCK OWNERSHIP.

            9.1 Voting and Dividends. No Participant shall have any of the
rights of a shareholder with respect to any Shares until the Shares are issued
to the Participant. After Shares are issued to the Participant, the Participant
shall be a shareholder and have all the rights of a shareholder with respect to
such Shares, including the right to vote and receive all dividends or other
distributions made or paid with respect to such Shares; provided, that if such
Shares are Restricted Stock, then any new, additional or different securities
the Participant may become entitled to receive with respect to such Shares by
virtue of a stock dividend, stock split or any other change in the corporate or
capital structure of the Company shall be subject to the same restrictions as
the Restricted Stock; provided, further, that the Participant shall have no
right to retain such stock dividends or stock distributions with respect to
Unvested Shares that are repurchased pursuant to Section 11. The Company will
comply with Section 260.140.1 of Title 10 of the California Code of Regulations
with respect to the voting rights of Common Stock.

            9.2 Financial Statements. The Company shall provide financial
statements to each Participant annually during the period such Participant has
Awards outstanding or as otherwise required under Section 260.140.46 of Title 10
of the California Code of Regulations. Notwithstanding the foregoing, the
Company shall not be required to provide such financial statements to
Participants when issuance is limited to key employees whose services in
connection with the Company assure them access to equivalent information.

         10. TRANSFERABILITY. Awards granted under the Plan, and any interest
therein, shall not be transferable or assignable by Participant, other than by
will or by the laws of descent and distribution, and may not be made subject to
execution, attachment or similar process. During the lifetime of the Participant
an Award shall be exercisable only by the Participant, or Participant's legal
representative, and any elections with respect to an Award may be made only by
the Participant or Participant's legal representative.

         11. RESTRICTIONS ON SHARES.

             11.1 Right of First Refusal. At the discretion of the Committee,
the Company may reserve to itself and/or its assignee(s) in the Award Agreement
(a) a right of first refusal to purchase all Shares that a Participant (or a
subsequent transferee) may propose to transfer to a third party, unless
otherwise not permitted by Section 25102(o) of the California Corporations Code,
provided that such right of first refusal terminates upon the Company's initial
public offering of Common Stock pursuant to an effective registration statement
filed under the Securities Act.

             11.2 Right of Repurchase. At the discretion of the Committee, the
Company may reserve to itself and/or its assignee(s) in the Award Agreement a
right to repurchase a portion of or all Unvested Shares held by a Participant
following such Participant's Termination at any time within ninety (90) days
after the later of Participant's Termination Date and the date Participant
purchases Shares under the Plan, for cash or cancellation of purchase money
indebtedness, at: (A) with respect to Shares that are "Vested" (as defined in
the Award Agreement), the Fair Market Value of such Shares on Participant's
Termination Date, provided, that such right of repurchase (i) must be exercised
as to all such "Vested" Shares unless a Participant consents to the Company's
repurchase of only a portion of such "Vested" Shares and (ii) terminates when
the Company's securities become publicly traded; or (B) with respect to Shares
that are not "Vested" (as defined in the Award Agreement), at the Participant's
original Purchase Price or Exercise Price, as the case may be, or such higher
price as determined by the Committee, provided, that to the extent the
Participant is not an officer, director or consultant of the Company, or of a
Parent or Subsidiary of the Company, such right of repurchase in this Subsection
(B) lapses at the rate of at least 20% per year over 5 years from the date the
Shares were purchased (or from the date of grant of options in the case of
Shares obtained pursuant to a Stock Option Agreement and Stock Option Exercise
Agreement).

         12. CERTIFICATES. All certificates for Shares or other securities
delivered under the Plan shall be subject to such stock transfer orders, legends
and other restrictions as the Committee may deem necessary or advisable,
including restrictions under any applicable federal, state or foreign securities
law, or any rules, regulations and other requirements of the SEC or any stock
exchange or automated quotation system upon which the Shares may be listed.

         13. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a
Participant's Shares in Section 11 hereof, the Committee may require the
Participant to deposit all certificates representing Shares, together with stock
powers or other instruments of transfer approved by the Committee, appropriately
endorsed in blank, with the Company or an agent designated by the Company to
hold in escrow until such restrictions have lapsed or terminated, and the
Committee may cause a legend or legends referencing such restrictions to be
placed on the certificates. Any Participant who is permitted to execute a
promissory note as partial or full consideration for the purchase of Shares
under the Plan shall be required to pledge and deposit with the Company all or
part of the Shares so purchased as collateral to secure the payment of
Participant's obligation to the Company under the promissory note; provided,
however, that the Committee may require or accept other or additional forms of
collateral to secure the payment of such obligation and, in any event, the
Company shall have full recourse against the Participant


                                      -9-
<PAGE>   10

under the promissory note notwithstanding any pledge of the Participant's Shares
or other collateral. In connection with any pledge of the Shares, Participant
shall be required to execute and deliver a written pledge agreement in such form
as the Committee shall from time to time approve. The Shares purchased with the
promissory note may be released from the pledge on a prorata basis as the
promissory note is paid.

         14. EXCHANGE AND BUYOUT OF AWARDS. The Committee may, at any time or
from time to time, authorize the Company, with the consent of the respective
Participants, to issue new Awards in exchange for the surrender and cancellation
of any or all outstanding Awards. The Committee may at any time buy from a
Participant an Award previously granted with payment in cash, shares of Common
Stock of the Company (including Restricted Stock) or other consideration, based
on such terms and conditions as the Committee and the Participant shall agree.

         15. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. This Plan is
intended to comply with Section 25102(o) of the California Corporations Code.
Any provision of this Plan which is inconsistent with Section 25102(o) shall,
without further act or amendment by the Company or the Board, be reformed to
comply with the requirements of Section 25102(o). An Award shall not be
effective unless such Award is in compliance with all applicable federal and
state securities laws, rules and regulations of any governmental body, and the
requirements of any stock exchange or automated quotation system upon which the
Shares may then be listed or quoted, as they are in effect on the date of grant
of the Award and also on the date of exercise or other issuance. Notwithstanding
any other provision in the Plan, the Company shall have no obligation to issue
or deliver certificates for Shares under the Plan prior to (a) obtaining any
approvals from governmental agencies that the Company determines are necessary
or advisable, and/or (b) compliance with any exemption, completion of any
registration or other qualification of such Shares under any state or federal
law or ruling of any governmental body that the Company determines to be
necessary or advisable. The Company shall be under no obligation to register the
Shares with the SEC or to effect compliance with the exemption, registration,
qualification or listing requirements of any state securities laws, stock
exchange or automated quotation system, and the Company shall have no liability
for any inability or failure to do so.

         16. NO OBLIGATION TO EMPLOY. Nothing in the Plan or any Award granted
under the Plan shall 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 Parent, Subsidiary or Affiliate of the Company or limit in any
way the right of the Company or any Parent, Subsidiary or Affiliate of the
Company to terminate Participant's employment or other relationship at any time,
with or without Cause.

         17. CORPORATE TRANSACTIONS.

             17.1 Assumption or Replacement of Awards by Successor or Acquiring
Corporation. In the event of (a) a merger or consolidation in which the Company
is not the surviving corporation (other than a merger or consolidation with a
wholly-owned subsidiary, a reincorporation of the Company in a different
jurisdiction, or other transaction in which there is no substantial change in
the shareholders of the Company or their relative stock holdings and the


                                      -10-
<PAGE>   11

Awards granted under the Plan are assumed, converted or replaced by the
successor or acquiring corporation, which assumption, conversion or replacement
shall be binding on all Participants), (b) a dissolution or liquidation of the
Company, (c) the sale of substantially all of the assets of the Company, or (d)
a merger in which the Company is the surviving corporation but after which the
shareholders of the Company immediately prior to such merger (other than any
shareholder which merges with the Company in such merger, or which owns or
controls another corporation which merges with the Company in such merger) cease
to own their shares or other equity interests in the Company, any or all
outstanding Awards may be assumed, converted or replaced by the successor
corporation (if any), which assumption, conversion or replacement shall be
binding on all Participants. In the alternative, the successor or acquiring
corporation may substitute equivalent Awards or provide substantially similar
consideration to Participants as was provided to shareholders (after taking into
account the existing provisions of the Awards). The successor or acquiring
corporation may also issue, in place of outstanding Shares of the Company held
by the Participant, substantially similar shares or other property subject to
repurchase restrictions and other restrictions no less favorable to the
Participant than those which applied to such outstanding Shares immediately
prior to such transaction described in this Section 17.1.

             In the event such successor or acquiring corporation (if any)
refuses to assume or substitute Awards, as provided above, pursuant to a
transaction described in this Subsection 17.1, then notwithstanding any other
provision in this Plan to the contrary, such Awards shall expire on such
transaction at such time and on such conditions as the Board shall determine.

             17.2 Other Treatment of Awards. Subject to any greater rights
granted to Participants under the foregoing provisions of this Section 17, in
the event of the occurrence of any transaction described in Section 17.1, any
outstanding Awards shall be treated as provided in the applicable agreement or
plan of merger, consolidation, dissolution, liquidation, sale of assets or other
"corporate transaction."

             17.3 Assumption of Awards by the Company. The Company, from time to
time, also may substitute or assume outstanding awards granted by another
company, whether in connection with an acquisition of such other company or
otherwise, by either (a) granting an Award under the Plan in substitution of
such other company's award, or (b) assuming such award as if it had been granted
under the Plan if the terms of such assumed award could be applied to an Award
granted under the Plan. Such substitution or assumption shall be permissible if
the holder of the substituted or assumed award would have been eligible to be
granted an Award under the Plan if the other company had applied the rules of
the Plan to such grant. In the event the Company assumes an award granted by
another company, the terms and conditions of such award shall remain unchanged
(except that the exercise price and the number and nature of Shares issuable
upon exercise of any such option will be adjusted appropriately pursuant to
Section 424(a) of the Code). In the event the Company elects to grant a new
Option rather than assuming an existing option, such new Option may be granted
with a similarly adjusted Exercise Price.

         18. ADOPTION AND SHAREHOLDER APPROVAL. The Plan shall become effective
on the date that it is adopted by the Board (the "Effective Date"). The Plan
shall be approved by the shareholders of the Company (excluding Shares issued
pursuant to this Plan),


                                      -11-
<PAGE>   12

consistent with applicable laws, within twelve months before or after the
Effective Date. Upon the Effective Date, the Board may grant Awards pursuant to
the Plan; provided, however, that: (a) no Option may be exercised prior to
initial shareholder approval of the Plan; (b) no Option granted pursuant to an
increase in the number of Shares approved by the Board shall be exercised prior
to the time such increase has been approved by the shareholders of the Company;
(c) in the event that initial shareholder approval is not obtained within the
time period provided herein, all Awards granted hereunder shall be cancelled,
any Shares issued pursuant to any Award shall be cancelled and any purchase of
Shares hereunder shall be rescinded; and (d) Awards granted pursuant to an
increase in the number of Shares approved by the Board which increase is not
timely approved by shareholders shall be canceled, any Shares issued pursuant to
any such Awards shall be canceled, and any purchase of Shares subject to any
such Award shall be rescinded.

         19. TERM OF PLAN AND GOVERNING LAW. Unless earlier terminated as
provided herein, this Plan will terminate ten (10) years from the Effective Date
or, if earlier, the date of shareholder approval. This Plan and all agreements
hereunder shall be governed by and construed in accordance with the laws of the
State of California.

         20. AMENDMENT OR TERMINATION OF PLAN. Subject to Section 5.9 hereof,
the Board may at any time terminate or amend the Plan in any respect, including
without limitation amendment of any form of Award Agreement or instrument to be
executed pursuant to the Plan; provided, however, that the Board shall not,
without the approval of the shareholders of the Company, amend the Plan in any
manner that requires such shareholder approval pursuant to the Code or the
regulations promulgated thereunder as such provisions apply to ISO plans or
Section 25102(o) of the California Corporations Code.

         21. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of the Plan by the
Board, the submission of the Plan to the shareholders of the Company for
approval, nor any provision of the Plan shall be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the
granting of stock options otherwise than under the Plan, and such arrangements
may be either generally applicable or applicable only in specific cases.

               1. GRANT OF OPTION. The Company hereby grants to Participant an
option (this "OPTION") to purchase the total number of shares of Common Stock of
the Company set forth above as Total Option Shares (the "SHARES") at the
Exercise Price Per Share set forth above (the "EXERCISE PRICE"), subject to all

Incentive Stock Option above, the Option is intended to qualify as an "incentive
stock option" (the "ISO") within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the "CODE").

               2. EXERCISE PERIOD.

                      2.1 Exercise Period of Option. Provided Participant
continues to provide services to the Company or any Subsidiary or Parent of the
Company, the Option will become vested and exercisable with respect to 25% of
the Shares on _______, __ (the "FIRST VESTING DATE") and thereafter at the end
of each month from the First Vesting Date, the Option shall become exercisable
as to 2.083% of the Shares, provided that for participants other than officers,
directors and consultants, the Option will become fully exercisable within five
years

                                       1

<PAGE>   17

from the Date of Grant with at least 20% of the total shares first
becoming exercisable at the end of each of the five years. If application of the
vesting percentage causes a fractional share, such share shall be rounded down
to the nearest whole share for each month except for the last month in such
vesting period, at the end of which last month this Option shall become
exercisable for the full remainder of the Shares.

                      2.2 Vesting of Options. Shares that are vested pursuant to
the schedule set forth in Section 2.1 are "VESTED SHARES." Shares that are not
vested pursuant to the schedule set forth in Section 2.1 are "UNVESTED SHARES."

                      2.3 Expiration. The Option shall expire on the Expiration
Date set forth above or earlier as provided in Section 3 below or pursuant to
Section 5.6 of the Plan.

               3. TERMINATION.

                      3.1 Termination for Any Reason Except Death, Disability or
Cause. If Participant is Terminated for any reason, except death, Disability or
for Cause, the Option, to the extent (and only to the extent) that it would have
been exercisable by Participant on the Termination Date, may be exercised by
Participant no later than three (3) months after the Termination Date, but in
any event no later than the Expiration Date.

                      3.2 Termination Because of Death or Disability. If
Participant is Terminated because of death or Disability of Participant (or
Participant dies within three (3) months of Termination when Termination is for
any reason other than Participant's Disability or for Cause), the Option, to the
extent that it is exercisable by Participant on the Termination Date, may be
exercised by Participant (or Participant's legal representative) no later than
twelve (12) months after the Termination Date, but in any event no later than
the Expiration Date. Any exercise beyond (i) three (3) months after the
Termination Date when the Termination is for any reason other than the
Participant's death or disability, within the meaning of Section 22(e)(3) of the
Code; or (ii) twelve (12) months after the Termination Date when the termination
is for Participant's disability, within the meaning of Section 22(e)(3) of the
Code, is deemed to be an NQSO.

                      3.3 Termination for Cause. If Participant is Terminated
for Cause, the Option shall cease to be exercisable by Participant immediately
upon such Termination, unless the Committee, in its sole discretion,
affirmatively decides otherwise and so informs the Participant in writing.
Termination for "Cause" shall mean Termination because of (i) any willful
material violation by the Participant of any law or regulation applicable to the
business of the Company or any of its Subsidiaries, the Participant's conviction
for, or guilty plea to, a felony or a crime involving moral turpitude, any
willful perpetration by the Participant of a common law fraud or any unlawful
use by the Participant of drugs or other controlled substances, (ii) the
Participant's commission of an act of personal dishonesty which involves
personal profit in connection with the Company or any other entity having a
business relationship with the Company, (iii) any material breach by the
Participant of any provision of any agreement or understanding between the
Company and the Participant regarding the terms of the Participant's service as
an employee, director, consultant, independent contractor or adviser to the
Company or a Parent, Subsidiary or Affiliate of the Company, including without
limitation, the willful and continued failure or refusal of the Participant to
perform the material duties required of him as an employee, director,
consultant, independent contractor or adviser of the Company or a Parent,

Subsidiary or Affiliate of the Company, other than as a result of being
Disabled, or a breach of any applicable Invention Assignment and Confidentiality
Agreement or similar agreement between the Company and the Participant, (iv)
Participant's disregard of the policies of the Company so as to cause loss,

their respective Parents, Subsidiaries or Affiliates, or (v) any other
misconduct by the Participant which is materially injurious to the financial
condition or business reputation of, or is otherwise materially injurious to,
the Company or any of its Parents, Subsidiaries or Affiliates, then the Option
will expire on Participant's Termination Date, or at such later time and on such
conditions as are determined by the Committee.

                      3.4 No Obligation to Employ. Nothing in the Plan or this
Agreement shall confer on Participant any right to continue in the employ of, or
other relationship with, the Company or any Parent or Subsidiary of the Company,
or limit in any way the right of the Company or any Parent or Subsidiary of the
Company to terminate Participant's employment or other relationship at any time,
with or without Cause.

               4. MANNER OF EXERCISE.

                      4.1 Stock Option Exercise Agreement. To exercise this
Option, Participant (or in the case of exercise after Participant's death or
incapacity, Participant's executor, administrator, heir or legatee, as the case
may be) must deliver to the Company an executed stock option exercise agreement
in the form attached hereto as Exhibit A, or in such other form as may be
approved by the Committee from time to time (the "EXERCISE AGREEMENT"), which
shall set forth, inter alia, (i) Participant's election to exercise the Option,
(ii) the number of Shares being purchased, (iii) any restrictions imposed on the
Shares and (iv) any representations, warranties and agreements regarding
Participant's investment intent and access to information as may be required by
the Company to comply with applicable securities laws. If someone other than
Participant exercises the Option, then such person must submit documentation
reasonably acceptable to the Company verifying that such person has the legal
right to exercise the Option.

                      4.2 Limitations on Exercise. The Option may not be
exercised unless such exercise is in compliance with all applicable federal and
state securities laws, as they are in effect on the date of exercise. The Option
may not be exercised as to fewer than one hundred (100) Shares unless it is
exercised as to all Shares as to which the Option is then exercisable.

                      4.3 Payment. The Exercise Agreement shall be accompanied
by full payment of the Exercise Price for the shares being purchased in cash (by
check), or where permitted by law:

                (a)    by cancellation of indebtedness of the Company to the
                       Participant;

                (b)    by surrender of shares of the Company's Common Stock
                       that (i) either (A) have been owned by Participant for
                       more than six (6) months and have been paid for within
                       the meaning of SEC Rule 144 (and, if such shares were
                       purchased from the Company by use of a promissory note,
                       such note has been fully paid with respect to such
                       shares); or (B) were obtained by Participant in the open
                       public market; and (ii) are clear of all liens, claims,
                       encumbrances or security interests;

                                       3
<PAGE>   19

                (c)    by waiver of compensation due or accrued to Participant
                       for services rendered;

                (d)    provided that a public market for the Company's stock
                       exists: (i) through a "same day sale" commitment from
                       Participant and a broker-dealer that is a member of the
                       National Association of Securities Dealers (an "NASD
                       DEALER") whereby Participant irrevocably elects to
                       exercise the Option and to sell a portion of the Shares
                       so purchased sufficient to pay for the total Exercise
                       Price and whereby the NASD Dealer irrevocably commits
                       upon receipt of such Shares to forward the total
                       Exercise Price directly to the Company, or (ii) through
                       a "margin" commitment from Participant and an NASD
                       Dealer whereby Participant irrevocably elects to
                       exercise the Option and to pledge the Shares so
                       purchased to the NASD Dealer in a margin account as
                       security for a loan from the NASD Dealer in the amount
                       of the total Exercise Price, and whereby the NASD Dealer
                       irrevocably commits upon receipt of such Shares to
                       forward the total Exercise Price directly to the
                       Company; or

                (e)    by any combination of the foregoing.

                      4.4 Tax Withholding. Prior to the issuance of the Shares
upon exercise of the Option, Participant must pay or provide for any applicable
federal, state and local withholding obligations of the Company. If the
Committee permits, Participant may provide for payment of withholding taxes upon
exercise of the Option by requesting that the Company retain Shares with a Fair
Market Value equal to the minimum amount of taxes required to be withheld. In
such case, the Company shall issue the net number of Shares to the Participant
by deducting the Shares retained from the Shares issuable upon exercise.

                      4.5 Issuance of Shares. Provided that the Exercise
Agreement and payment are in form and substance satisfactory to counsel for the
Company, the Company shall issue the Shares registered in the name of
Participant, Participant's authorized assignee, or Participant's legal
representative, and shall deliver certificates representing the Shares with the
appropriate legends affixed thereto.

               5. NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES. If the
Option is an ISO, and if Participant sells or otherwise disposes of any of the
Shares acquired pursuant to the ISO on or before the later of (i) the date two
(2) years after the Date of Grant, and (ii) the date one (1) year after transfer
of such Shares to Participant upon exercise of the Option, Participant shall
immediately notify the Company in writing of such disposition. Participant
agrees that Participant may be subject to income tax withholding by the Company
on the compensation income recognized by Participant from the early disposition
by payment in cash or out of the current wages or other compensation payable to
Participant.

               6. COMPLIANCE WITH LAWS AND REGULATIONS. The Plan and this
Agreement are intended to comply with Section 25102(o) of the California
Corporations Code and any regulations relating thereto. Any provision of this
Agreement which is inconsistent with Section 25102(o) or any regulations
relating thereto shall, without further act or amendment by the Company or the
Board, be reformed to comply with the requirements of Section 25102(o) and any
regulations relating thereto. The exercise of the Option and the issuance and
transfer of



                                       4
<PAGE>   20

Shares shall be subject to compliance by the Company and Participant with all
applicable requirements of federal and state securities laws and with all
applicable requirements of any stock exchange on which the Company's Common
Stock may be listed at the time of such issuance or transfer. Participant
understands that the Company is under no obligation to register or qualify the
Shares with the SEC, any state securities commission or any stock exchange to
effect such compliance.

               7. NONTRANSFERABILITY OF OPTION. The Option may not be
transferred in any manner other than by will or by the laws of descent and
distribution and may be exercised during the lifetime of Participant only by
Participant or in the event of Participant's incapacity, by Participant's legal
representative. The terms of the Option shall be binding upon the executors,
administrators, successors and assigns of Participant.

               8. COMPANY'S REPURCHASE OPTION FOR UNVESTED SHARES. The Company,
or its assignee, shall have the option to repurchase Participant's Unvested
Shares (as defined in Section 2.2 of this Agreement) on the terms and conditions
set forth in the Exercise Agreement (the "REPURCHASE OPTION") if Participant is
Terminated (as defined in the Plan) for Cause (as defined in Section 3.3
hereof).

                      8.1 Termination and Termination Date. In case of any
dispute as to whether Participant is Terminated for Cause, the Committee shall
have discretion to determine whether Participant has been Terminated for Cause
and the effective date of such Termination (the "Cause Termination Date").

                      8.2 Exercise of Repurchase Option. At any time within
ninety (90) days after the later of the Cause Termination Date or the date
Participant purchased the Shares, the Company, or its assignee, may elect to
repurchase the Participant's Unvested Shares by giving Participant written
notice of exercise of the Repurchase Option for Unvested Shares.

                      8.3 Calculation of Repurchase Price for Vested Shares. The
Company or its assignee shall have the option to repurchase from Participant (or
from Participant's personal representative as the case may be) the Unvested
Shares at the Fair Market Value of such shares on the Participant's Cause
Termination Date or such higher price as determined by the Committee.

                      8.4 Payment of Repurchase Price. The repurchase price
shall be payable, at the option of the Company or its assignee, by check or by
cancellation of all or a portion of any outstanding indebtedness of Participant
to the Company or such assignee, or by any combination thereof. The repurchase
price shall be paid without interest within sixty (60) days after exercise of
the Repurchase Option for Unvested Shares.

                      8.5 Right of Termination Unaffected. Nothing in this
Agreement shall be construed to limit or otherwise affect in any manner
whatsoever the right or power of the Company (or any Parent or Subsidiary of the
Company) to terminate Participant's employment or other relationship with
Company (or the Parent or Subsidiary of the Company) at any time, for any reason
or no reason, with or without cause.

                      8.6 Termination of Repurchase Option. The Company's
Repurchase Options for Unvested Shares will terminate upon the closing of the
first sale of Common Stock



                                       5
<PAGE>   21

of the Company to the general public pursuant to a registration statement filed
with and declared effective by the SEC (other than a registration statement
solely covering an employee benefit plan or corporate reorganization).

               9. COMPANY'S RIGHT OF FIRST REFUSAL. Unvested Shares may not be
sold or otherwise transferred by Participant without the Company's prior written
consent. Before any Vested Shares held by Participant or any transferee of such
Vested Shares (either being sometimes referred to herein as the "Holder") may be
sold or otherwise transferred (including without limitation a transfer by gift
or operation of law), the Company and/or its assignee(s) shall have an
assignable right of first refusal to purchase the Vested Shares to be sold or
transferred (the "Offered Shares") on the terms and conditions set forth in this
Section (the "Right of First Refusal").

                      9.1 Notice of Proposed Transfer. The Holder of the Offered
Shares shall deliver to the Company a written notice (the "Notice") stating: (i)
the Holder's bona fide intention to sell or otherwise transfer the Offered
Shares; (ii) the name of each proposed bona fide purchaser or other transferee
("Proposed Transferee"); (iii) the number of Offered Shares to be transferred to
each Proposed Transferee; (iv) the bona fide cash price or other consideration
for which the Holder proposes to transfer the Offered Shares (the "Offered
Price"); and (v) that the Holder will offer to sell the Offered Shares to the
Company and/or its assignee(s) at the Offered Price as provided in this Section.

                      9.2 Exercise of Right of First Refusal. At any time within
thirty (30) days after the date of the Notice, the Company and/or its
assignee(s) may, by giving written notice to the Holder, elect to purchase all
(or, with the consent of the Holder, less than all) of the Offered Shares
proposed to be transferred to any one or more of the Proposed Transferees named
in the Notice, at the purchase price determined as specified below.

                      9.3 Purchase Price. The purchase price for the Offered
Shares purchased under this Section will be the Offered Price. If the Offered
Price includes consideration other than cash, then the cash equivalent value of
the non-cash consideration shall conclusively be deemed to be the value of such
non-cash consideration as determined in good faith by the Company's Board of
Directors.

                      9.4 Payment. Payment of the purchase price for Offered
Shares will be payable, at the option of the Company and/or its assignee(s) (as
applicable), by check or by cancellation of all or a portion of any outstanding
indebtedness of the Holder to the Company (or to such assignee, in the case of a
purchase of Offered Shares by such assignee) or by any combination thereof. The
purchase price will be paid without interest within sixty (60) days after the
Company's receipt of the Notice, or, at the option of the Company and/or its
assignee(s), in the manner and at the time(s) set forth in the Notice.

                      9.5 Holder's Right to Transfer. If all of the Offered
Shares proposed in the Notice to be transferred to a given Proposed Transferee
are not purchased by the Company and/or its assignee(s) as provided in this
Section, then the Holder may sell or otherwise transfer such Offered Shares to
that Proposed Transferee at the Offered Price or at a higher price, provided
that such sale or other transfer is consummated within 120 days after the date
of the Notice, and provided further, that (i) any such sale or other transfer is
effected in compliance with all applicable securities laws and (ii) the Proposed
Transferee agrees in writing that the



                                       6
<PAGE>   22

provisions of this Section will continue to apply to the Offered Shares in the
hands of such Proposed Transferee. If the Offered Shares described in the Notice
are not transferred to the Proposed Transferee within such 120 day period, then
a new Notice must be given to the Company, and the Company will again be offered
the Right of First Refusal before any Shares held by the Holder may be sold or
otherwise transferred.

                      9.6 Exempt Transfers. Notwithstanding anything to the
contrary in this Section, the following transfers of Vested Shares will be
exempt from the Right of First Refusal: (i) the transfer of any or all of the
Vested Shares during Participant's lifetime by gift or on Participant's death by
will or intestacy to Participant's "immediate family" (as defined below) or to a
trust for the benefit of Participant or Participant's immediate family, provided
that each transferee or other recipient agrees in a writing satisfactory to the
Company that the provisions of this Section will continue to apply to the
transferred Vested Shares in the hands of such transferee or other recipient;
(ii) any transfer of Vested Shares made pursuant to a statutory merger or
statutory consolidation of the Company with or into another corporation or
corporations (except that the Right of First Refusal and Repurchase Option will
continue to apply thereafter to such Vested Shares, in which case the surviving
corporation of such merger or consolidation shall succeed to the rights of the
Company under this Section unless the agreement of merger or consolidation
expressly otherwise provides); or (iii) any transfer of Vested Shares pursuant
to the winding up and dissolution of the Company. As used herein, the term
"immediate family" will mean Participant's spouse, the lineal descendant or
antecedent, father, mother, brother or sister, adopted child or grandchild of
the Participant or the Participant's spouse, or the spouse of any child, adopted
child, grandchild or adopted grandchild of Participant or the Participant's
spouse.

                      9.7 Termination of Right of First Refusal. The Company's
Right of First Refusal will terminate upon the closing of the first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the SEC (other than a
registration statement solely covering an employee benefit plan or corporate
reorganization).

               10. TAX CONSEQUENCES. Set forth below is a brief summary as of
the Effective Date of the Plan of some of the federal and California tax
consequences of exercise of the Option and disposition of the Shares. THIS
SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT
TO CHANGE. PARTICIPANT SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THE OPTION
OR DISPOSING OF THE SHARES.

                      10.1 Exercise of ISO. If the Option qualifies as an ISO,
there will be no regular federal or California income tax liability upon the
exercise of the Option, although the excess, if any, of the Fair Market Value of
the Shares on the date of exercise over the Exercise Price will be treated as a
tax preference item for federal alternative minimum tax purposes and may subject
the Participant to the alternative minimum tax in the year of exercise.

                      10.2 Exercise of Nonqualified Stock Option. If the Option
does not qualify as an ISO, there may be a regular federal and California income
tax liability upon the exercise of the Option. Participant will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess, if any, of the Fair Market Value of the Shares on the date of
exercise over the Exercise Price. If Participant is a current or former



                                       7
<PAGE>   23

employee of the Company, the Company may be required to withhold from
Participant's compensation or collect from Participant and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

                      10.3 Disposition of Shares. The following tax consequences
may apply upon disposition of the Shares.

                              (a) Incentive Stock Options. If the Shares are
held for more than twelve (12) months after the date of the transfer of the
Shares pursuant to the exercise of an ISO and are disposed of more than two (2)
years after the Date of Grant, any gain realized on disposition of the Shares
will be treated as long term capital gain for federal and California income tax
purposes. If Shares purchased under an ISO are disposed of within the applicable
one (1) year or two (2) year period, any gain realized on such disposition will
be treated as compensation income (taxable at ordinary income rates) to the
extent of the excess, if any, of the Fair Market Value of the Shares on the date
of exercise over the Exercise Price.

                              (b) Nonqualified Stock Options. If the Shares are
held for more than twelve (12) months after the date of the transfer of the
Shares pursuant to the exercise of an NQSO, any gain realized on disposition of
the Shares will be treated as long term capital gain.

                              (c) Withholding. The Company may be required to
withhold from the Participant's compensation or collect from the Participant and
pay to the applicable taxing authorities an amount equal to a percentage of this
compensation income.

                      10.4. Section 83(b) Election for Unvested Shares. With
respect to Unvested Shares, which are subject to the Repurchase Option, unless
an election is filed by the Participant with the Internal Revenue Service (and,
if necessary, the proper state taxing authorities), within 30 days of the
purchase of the Unvested Shares, electing pursuant to Section 83(b) of the Code
(and similar state tax provisions, if applicable) to be taxed currently on any
difference between the Exercise Price of the Unvested Shares and their Fair
Market Value on the date of purchase, there may be a recognition of taxable
income (including, where applicable, alternative minimum taxable income) to the
Participant, measured by the excess, if any, of the Fair Market Value of the
Unvested Shares at the time they cease to be Unvested Shares, over the Exercise
Price of the Unvested Shares.

               11. PRIVILEGES OF STOCK OWNERSHIP. Participant shall not have any
of the rights of a shareholder with respect to any Shares until the Shares are
issued to Participant.

               12. INTERPRETATION. Any dispute regarding the interpretation of
this Agreement shall be submitted by Participant or the Company to the Committee
for review. The resolution of such a dispute by the Committee shall be final and
binding on the Company and Participant.

               13. ENTIRE AGREEMENT. The Plan is incorporated herein by
reference. This Agreement and the Plan constitute the entire agreement of the
parties and supersede all prior undertakings and agreements with respect to the
subject matter hereof.

                                       8
<PAGE>   24

               14. NOTICES. Any notice required to be given or delivered to the
Company under the terms of this Agreement shall be in writing and addressed to
the Corporate Secretary of the Company at its principal corporate offices. Any
notice required to be given or delivered to Participant shall be in writing and
addressed to Participant at the address indicated above or to such other address
as such party may designate in writing from time to time to the Company. All
notices shall be deemed to have been given or delivered upon: (i) personal
delivery; (ii) three (3) days after deposit in the United States mail by
certified or registered mail (return receipt requested); (iii) one (1) business
day after deposit with any return receipt express courier (prepaid); or (iv) one
(1) business day after transmission by facsimile, rapifax or telecopier.

               15. SUCCESSORS AND ASSIGNS. The Company may assign any of its
rights under this Agreement. This Agreement shall be binding upon and inure to
the benefit of the successors and assigns of the Company. Subject to the
restrictions on transfer set forth herein, this Agreement shall be binding upon
Participant and Participant's heirs, executors, administrators, legal
representatives, successors and assigns.

               16. GOVERNING LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of California as such laws
are applied to agreements between California residents entered into and to be
performed entirely within California. If any provision of this Agreement is
determined by a court of law to be illegal or unenforceable, then such provision
will be enforced to the maximum extent possible and the other provisions will
remain fully effective and enforceable.

               17. ACCEPTANCE. Participant hereby acknowledges receipt of a copy
of the Plan and this Agreement. Participant has read and understands the terms
and provisions thereof, and accepts the Option subject to all the terms and
conditions of the Plan and this Agreement. Participant acknowledges that there
may be adverse tax consequences upon exercise of the Option or disposition of
the Shares and that Participant should consult a tax adviser prior to such
exercise or disposition.

               IN WITNESS WHEREOF, the Company has caused this Agreement to be
executed in triplicate by its duly authorized representative and Participant has
executed this Agreement in triplicate, effective as of the Date of Grant.

                                least six (6) months prior to the date hereof
                                which have been paid for within the meaning of
                                SEC Rule 144, (if purchased by use of a
                                promissory note, such note has been fully paid
                                with respect to such vested shares), or obtained

                       [ ]      by the waiver hereby of compensation due or
                                accrued for services rendered in the amount of
                                $_________.

        2. DELIVERY.

               2.1 Deliveries by Purchaser. Purchaser hereby delivers to the
Company (i) this Exercise Agreement, (ii) two (2) copies of a blank Stock Power
and Assignment Separate from Stock Certificate in the form of Exhibit 1 attached
hereto (the "STOCK POWERS"), both executed by Purchaser (and Purchaser's spouse,
if any), (iii) if Purchaser is married, a Consent of



                                       2
<PAGE>   29

Spouse in the form of Exhibit 2 attached hereto (the "SPOUSE CONSENT") executed
by Purchaser's spouse, and (iv) the Purchase Price.

               2.2 Deliveries by the Company. Upon its receipt of the Exercise
Price, payment or other provision for any applicable tax obligations and all the
documents to be executed and delivered by Purchaser to the Company under Section
2.1, the Company will issue a duly executed stock certificate evidencing the
Shares in the name of Purchaser to be placed in escrow as provided in Section 11
to secure payment of Purchaser's obligation to the Company under the promissory
note and until expiration or termination of the Company's Repurchase Option and
Right of First Refusal described in Sections 8, 9 and 10.

        3. REPRESENTATIONS AND WARRANTIES OF PURCHASER. Purchaser represents and
warrants to the Company that:

               3.1 Agrees to Terms of the Plan. Purchaser has received a copy of
the Plan and the Stock Option Agreement, has read and understands the terms of
the Plan, the Stock Option Agreement and this Exercise Agreement, and agrees to
be bound by their terms and conditions. Purchaser acknowledges that there may be
adverse tax consequences upon exercise of the Option or disposition of the
Shares, and that Purchaser should consult a tax adviser prior to such exercise
or disposition.

               3.2 Purchase for Own Account for Investment. Purchaser is
purchasing the Shares for Purchaser's own account for investment purposes only
and not with a view to, or for sale in connection with, a distribution of the
Shares within the meaning of the Securities Act of 1933, as amended (the
"SECURITIES ACT"). Purchaser has no present intention of selling or otherwise
disposing of all or any portion of the Shares and no one other than Purchaser
has any beneficial ownership of any of the Shares.

               3.3 Access to Information. Purchaser has had access to all
information regarding the Company and its present and prospective business,
assets, liabilities and financial condition that Purchaser reasonably considers
important in making the decision to purchase the Shares, and Purchaser has had
ample opportunity to ask questions of the Company's representatives concerning
such matters and this investment.

               3.4 Understanding of Risks. Purchaser is fully aware of: (i) the
highly speculative nature of the investment in the Shares; (ii) the financial
hazards involved; (iii) the lack of liquidity of the Shares and the restrictions
on transferability of the Shares (e.g., that Purchaser may not be able to sell
or dispose of the Shares or use them as collateral for loans); (iv) the
qualifications and backgrounds of the management of the Company; and (v) the tax
consequences of investment in the Shares. Purchaser is capable of evaluating the
merits and risks of this investment, has the ability to protect Purchaser's own
interests in this transaction and is financially capable of bearing a total loss
of this investment.

               3.5 No General Solicitation. At no time was Purchaser presented
with or solicited by any publicly issued or circulated newspaper, mail, radio,
television or other form of general advertising or solicitation in connection
with the offer, sale and purchase of the Shares.

        4. COMPLIANCE WITH SECURITIES LAWS.

                                       3
<PAGE>   30

               4.1 Compliance with U.S. Federal Securities Laws. Purchaser
understands and acknowledges that the Shares have not been registered with the
Securities and Exchange Commission ("SEC") under the Securities Act and that,
notwithstanding any other provision of the Stock Option Agreement to the
contrary, the exercise of any rights to purchase any Shares is expressly
conditioned upon compliance with the Securities Act and all applicable state
securities laws. Purchaser agrees to cooperate with the Company to ensure
compliance with such laws. The Shares are being issued under the Securities Act
pursuant to the exemption provided by SEC Rule 701.

               4.2 Compliance with California Securities Laws. THE PLAN, THE
STOCK OPTION AGREEMENT, AND THIS EXERCISE AGREEMENT ARE INTENDED TO COMPLY WITH
SECTION 25102(o) OF THE CALIFORNIA CORPORATIONS CODE AND ANY RULES (INCLUDING
COMMISSIONER RULES, IF APPLICABLE) OR REGULATIONS PROMULGATED THEREUNDER BY THE
CALIFORNIA DEPARTMENT OF CORPORATIONS (THE "REGULATIONS"). ANY PROVISION OF THIS
EXERCISE AGREEMENT WHICH IS INCONSISTENT WITH SECTION 25102(o) SHALL, WITHOUT
FURTHER ACT OR AMENDMENT BY THE COMPANY OR THE BOARD, BE REFORMED TO COMPLY WITH
THE REQUIREMENTS OF SECTION 25102(o). THE SALE OF THE SECURITIES THAT ARE THE
SUBJECT OF THIS EXERCISE AGREEMENT, IF NOT YET QUALIFIED WITH THE CALIFORNIA
COMMISSIONER OF CORPORATIONS AND NOT EXEMPT FROM SUCH QUALIFICATION, IS SUBJECT
TO SUCH QUALIFICATION, AND THE ISSUANCE OF SUCH SECURITIES, AND THE RECEIPT OF
ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO SUCH QUALIFICATION IS UNLAWFUL
UNLESS THE SALE IS EXEMPT. THE RIGHTS OF THE PARTIES TO THIS EXERCISE AGREEMENT
ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED OR AN EXEMPTION
BEING AVAILABLE.

        5. RESTRICTED SECURITIES.

               5.1 No Transfer Unless Registered or Exempt. Purchaser
understands that Purchaser may not transfer any Shares unless such Shares are
registered under the Securities Act or qualified under applicable state
securities laws or unless, in the opinion of counsel to the Company, exemptions
from such registration and qualification requirements are available. Purchaser
understands that only the Company may file a registration statement with the SEC
and that the Company is under no obligation to do so with respect to the Shares.
Purchaser has also been advised that exemptions from registration and
qualification may not be available or may not permit Purchaser to transfer all
or any of the Shares in the amounts or at the times proposed by Purchaser.

               5.2 SEC Rule 144. In addition, Purchaser has been advised that
SEC Rule 144 promulgated under the Securities Act, which permits certain limited
sales of unregistered securities, is not presently available with respect to the
Shares and, in any event, requires that the Shares be held for a minimum of one
(1) year, and in certain cases two (2) years, after they have been purchased and
paid for (within the meaning of Rule 144). Purchaser understands that Shares
paid for with a promissory note may not be deemed to be fully "paid for" within
the meaning of Rule



                                       4
<PAGE>   31

144 unless certain conditions are met and that, accordingly, the Rule 144
holding period of such Shares may not begin to run until such Shares are fully
paid for within the meaning of Rule 144. Purchaser understands that Rule 144 may
indefinitely restrict transfer of the Shares so long as Purchaser remains an
"affiliate" of the Company or if "current public information" about the Company
(as defined in Rule 144) is not publicly available.

               5.3 SEC Rule 701. The Shares are issued pursuant to SEC Rule 701
promulgated under the Securities Act and may become freely tradeable by
non-affiliates (under limited conditions regarding the method of sale) ninety
(90) days after the first sale of Common Stock of the Company to the general
public pursuant to a registration statement filed with and declared effective by
the SEC, subject to the lengthier market standoff agreement contained in Section
7 of this Exercise Agreement or any other agreement entered into by Purchaser.
Affiliates must comply with the provisions (other than the holding period
requirements) of Rule 144.

        6.     RESTRICTIONS ON TRANSFERS.

               6.1 Disposition of Shares. Purchaser hereby agrees that Purchaser
shall make no disposition of the Shares (other than as permitted by this
Exercise Agreement) unless and until:

                      (a) Purchaser shall have notified the Company of the
proposed disposition and provided a written summary of the terms and conditions
of the proposed disposition;

                      (b) Purchaser shall have complied with all requirements of
this Exercise Agreement applicable to the disposition of the Shares;

                      (c) Purchaser shall have provided the Company with written
assurances, in form and substance satisfactory to counsel for the Company, that
(i) the proposed disposition does not require registration of the Shares under
the Securities Act or (ii) all appropriate actions necessary for compliance with
the registration requirements of the Securities Act or of any exemption from
registration available under the Securities Act (including Rule 144) have been
taken; and

                      (d) Purchaser shall have provided the Company with written
assurances, in form and substance satisfactory to the Company, that the proposed
disposition will not result in the contravention of any transfer restrictions
applicable to the Shares pursuant to the provisions of the Regulations referred
to in Section 4.2 hereof.

               6.2 Restriction on Transfer. Purchaser shall not transfer,
assign, grant a lien or security interest in, pledge, hypothecate, encumber or
otherwise dispose of any of the Shares which are subject to the Company's
Repurchase Option or the Company's Right of First Refusal described below,
except as permitted by this Exercise Agreement.

               6.3 Transferee Obligations. Each person (other than the Company)
to whom the Shares are transferred by means of one of the permitted transfers
specified in this Exercise Agreement must, as a condition precedent to the
validity of such transfer, acknowledge in writing to the Company that such
person is bound by the provisions of this Exercise Agreement and that the
transferred Shares are subject to (i) both the Company's Repurchase Option and
the



                                       5
<PAGE>   32

Company's Right of First Refusal granted hereunder and (ii)] the market
stand-off provisions of Section 7 hereof, to the same extent such Shares would
be so subject if retained by the Purchaser.

        7. MARKET STANDOFF AGREEMENT. Purchaser agrees in connection with any
registration of the Company's securities that, upon the request of the Company
or the underwriters managing any public offering of the Company's securities,
Purchaser will not sell or otherwise dispose of any Shares without the prior
written consent of the Company or such underwriters, as the case may be, for
such period of time (not to exceed one hundred eighty (180) days) after the
effective date of such registration requested by such managing underwriters and
subject to all restrictions as the Company or the underwriters may specify.
Purchaser further agrees to enter into any agreement reasonably required by the
underwriters to implement the foregoing.

        8. COMPANY'S REPURCHASE OPTION FOR UNVESTED SHARES. The Company, or its
assignee, shall have the option to repurchase Purchaser's Unvested Shares (as
defined in Section 2.2 of the Stock Option Agreement) on the terms and
conditions set forth in this Section (the "REPURCHASE OPTION") if Purchaser is
Terminated (as defined in the Plan) for any reason, or no reason, including
without limitation Purchaser's death, Disability (as defined in the Plan),
voluntary resignation or termination by the Company with or without Cause.
Notwithstanding the foregoing, the Company shall retain the Repurchase Option
for Unvested Shares only as to that number of Unvested Shares (whether or not
exercised) that exceeds the number of shares which remain unexercised.

               8.1 Termination and Termination Date. In case of any dispute as
to whether Purchaser is Terminated, the Committee shall have discretion to
determine whether Purchaser has been Terminated and the effective date of such
Termination (the "TERMINATION DATE").

               8.2 Exercise of Repurchase Option. At any time within ninety (90)
days after the Purchaser's Termination Date (or, in the case of securities
issued upon exercise of an Option after the Purchaser's Termination Date, within
ninety (90) days after the date of such exercise), the Company, or its assignee,
may elect to repurchase the Purchaser's Unvested Shares by giving Purchaser
written notice of exercise of the Repurchase Option.

               8.3 Calculation of Repurchase Price for Unvested Shares. The
Company or its assignee shall have the option to repurchase from Purchaser (or
from Purchaser's personal representative as the case may be) the Unvested Shares
at the Purchaser's Exercise Price, proportionately adjusted for any stock split
or similar change in the capital structure of the Company as set forth in
Section 2.2 of the Plan (the "REPURCHASE PRICE").

               8.4 Payment of Repurchase Price. The Repurchase Price shall be
payable, at the option of the Company or its assignee, by check or by
cancellation of all or a portion of any outstanding indebtedness owed by
Purchaser to the Company or such assignee, or by any combination thereof. The
Repurchase Price shall be paid without interest within sixty (60) days after
exercise of the Repurchase Option.

               8.5 Right of Termination Unaffected. Nothing in this Exercise
Agreement shall be construed to limit or otherwise affect in any manner
whatsoever the right or power of the Company (or any Parent, Subsidiary or
Affiliate of the Company) to terminate Purchaser's



                                       6
<PAGE>   33

employment or other relationship with Company (or the Parent, Subsidiary or
Affiliate of the Company) at any time, for any reason or no reason, with or
without Cause.

The Repurchase Option for Unvested Shares shall terminate as to any Unvested
Shares upon the closing of the first sale of Common Stock of the Company to the
general public pursuant to a registration statement filed with and declared
effective by the SEC (other than a registration statement solely covering an
employee benefit plan or corporate reorganization).

        9. COMPANY'S RIGHT OF FIRST REFUSAL. Unvested Shares may not be sold or
otherwise transferred by Purchaser without the Company's prior written consent.
Before any Vested Shares held by Purchaser or any transferee of such Vested
Shares (either being sometimes referred to herein as the "HOLDER") may be sold
or otherwise transferred by gift (including without limitation any transfer by
(i) an assignment of any Shares for the benefit of creditors of the Holder, (ii)
a transfer by operation of law, (iii) an execution of judgment against the
Shares or the acquisition of record or beneficial ownership of Shares by a
lender or creditor, (iv) a transfer by will or under the laws of descent and
distribution, (v) a transfer pursuant to any decree of divorce, dissolution or
separate maintenance, any property settlement, any separation agreement or any
other agreement with a spouse (except for bona fide estate planning purposes)
under which any Shares are transferred or awarded to the spouse of the Holder or
are required to be sold, or (vi) a transfer resulting from the filing by the
Holder of a petition for relief or the filing of an involuntary petition against
Holder, under the bankruptcy laws of the United States or of any other nation
(each instance referred to hereafter as the "INVOLUNTARY TRANSFER")), the
Company and/or its assignee(s) shall have an assignable right of first refusal
to purchase the Vested Shares to be sold or transferred (the "OFFERED SHARES")
on the terms and conditions set forth in this Section (the "RIGHT OF FIRST
REFUSAL").

               9.1 Notice of Proposed Transfer. In the event the Holder proposes
to transfer any Vested Shares, other than by an Involuntary Transfer, the Holder
of the Offered Shares shall deliver to the Company a written notice (the
"VOLUNTARY TRANSFER NOTICE") stating: (i) the Holder's bona fide intention to
sell or otherwise transfer the Offered Shares; (ii) the name of each proposed
bona fide purchaser or other transferee (the "PROPOSED TRANSFEREE"); (iii) the
number of Offered Shares to be transferred to each Proposed Transferee; (iv) the
bona fide cash price or other consideration for which the Holder proposes to
transfer the Offered Shares (the "OFFERED PRICE"); and (v) that the Holder
acknowledges this Notice is an offer to sell the Offered Shares to the Company
and/or its assignee(s) pursuant to the Company's Right of First Refusal at the
Offered Price as provided for in this Exercise Agreement. In the event of any
Involuntary Transfer of any Vested Shares, the Holder shall deliver to the
Company a written notice (the "INVOLUNTARY TRANSFER NOTICE") stating: (i) the
number of Shares subject to the Involuntary Transfer, (ii) the manner,
circumstances and date of the Involuntary Transfer, and (iii) the name and
address of the Holder and transferee. If the Company subsequently requests
additional information concerning the Involuntary Transfer or transferee, Holder
agrees to promptly provide the requested information to the Company.

               9.2 Exercise of Right of First Refusal. At any time within thirty
(30) days after the date of the Voluntary Transfer Notice or the Involuntary
Transfer Notice (either being sometimes referred to herein as the "NOTICE"), the
Company and/or its assignee(s) may, by giving written notice to the Holder,
elect to purchase all (or, with the consent of the Holder, less than



                                       7
<PAGE>   34

all) the Offered Shares proposed to be transferred to any one or more of the
Proposed Transferees named in the Notice, at the purchase price, determined as
specified below.

               9.3 Purchase Price. The purchase price for the Offered Shares
purchased under this Section will be the Offered Price. If no price or other
legal consideration is to be paid for the Shares, the transfer will be referred
to as a "DONATIVE TRANSFER". If the Offered Price includes consideration other
than cash, then the cash equivalent value of the non-cash consideration shall
conclusively be deemed to be the present Fair Market Value of such non-cash
consideration as conclusively determined in good faith by the Board of Directors
of the Company. In the case of a Donative Transfer or an Involuntary Transfer,
the Offered Price to be paid to the Holder by the Company or its assignee will
be the Fair Market Value on the proposed transfer date, as conclusively
determined in good faith by the Board of Directors of the Company.

               9.4 Payment. Payment of the Offered Price will be payable, at the
option of the Company and/or its assignee(s) (as applicable), by check or by
cancellation of all or a portion of any outstanding indebtedness owed by the
Holder to the Company (or to such assignee, in the case of a purchase of Offered
Shares by such assignee) or by any combination thereof. The Offered Price will
be paid without interest within sixty (60) days after the Company's receipt of
the Notice, or, at the option of the Company and/or its assignee(s), in the
manner and at the time(s) set forth in the Notice.

               9.5 Holder's Right to Transfer. If all of the Offered Shares
proposed in the Notice to be transferred to a given Proposed Transferee are not
purchased by the Company and/or its assignee(s) as provided in this Section,
then the Holder may sell or otherwise transfer such Offered Shares to that
Proposed Transferee at the Offered Price or at a higher price, provided (i) that
such sale or other transfer is consummated within one hundred twenty (120) days
after the date of the Notice, (ii) any such sale or other transfer is effected
in compliance with all applicable securities laws, and (iii) the Proposed
Transferee agrees in writing that the provisions of this Section will continue
to apply to the Offered Shares in the hands of such Proposed Transferee. If the
Offered Shares described in the Notice are not transferred to the Proposed
Transferee within such one hundred twenty (120) day period, then a new Notice
must be given to the Company pursuant to which the Company will again be offered
the Right of First Refusal before any Shares held by the Holder may be sold or
otherwise transferred.

               9.6 Exempt Transfers. Notwithstanding anything to the contrary in
this Section, the following transfers of Vested Shares will be exempt from the
Right of First Refusal: (i) the transfer of any or all of the Vested Shares
during Purchaser's lifetime by gift or on Purchaser's death by will or intestacy
to Purchaser's "Immediate Family" (as defined below) or to a trust for the
benefit of Purchaser or Purchaser's Immediate Family, provided that each
transferee or other recipient agrees in a writing satisfactory to the Company
that the provisions of this Section will continue to apply to the transferred
Vested Shares in the hands of such transferee or other recipient; (ii) any
transfer of Vested Shares made pursuant to a statutory merger or statutory
consolidation of the Company with or into another corporation or corporations
(except that the Right of First Refusal will continue to apply thereafter to
such Vested Shares, in which case the surviving corporation of such merger or
consolidation shall succeed to the rights of the Company under this Section
unless the agreement of merger or consolidation expressly otherwise provides);
or (iii) any transfer of Vested Shares pursuant to the



                                       8
<PAGE>   35

winding up and dissolution of the Company. As used herein, the term "IMMEDIATE
FAMILY" will mean Purchaser's spouse, the lineal descendant or antecedent,
father, mother, brother or sister, child, adopted child, grandchild or adopted
grandchild of the Purchaser or the Purchaser's spouse, or the spouse of any
child, adopted child, grandchild or adopted grandchild of Purchaser or the
Purchaser's spouse.

               9.7 Termination of Right of First Refusal. The Company's Right of
First Refusal will terminate when the Company's securities become publicly
traded.

      10. RIGHTS AS A SHAREHOLDER. Subject to the terms and conditions of this
Exercise Agreement, Purchaser will have all of the rights of a shareholder of
the Company with respect to the Shares from and after the date that Shares are
issued to Purchaser until such time as Purchaser disposes of the Shares or the
Company and/or its assignee(s) exercise(s) the Repurchase Option or Right of
First Refusal. Upon an exercise of the Repurchase Option or the Right of First
Refusal, Purchaser will have no further rights as a holder of the Shares so
purchased upon such exercise, other than the right to receive payment for the
Shares so purchased in accordance with the provisions of this Exercise
Agreement, and Purchaser will promptly surrender the stock certificate(s)
evidencing the Shares so purchased to the Company for transfer or cancellation.

      11. ESCROW. As security for Purchaser's faithful performance of this
Exercise Agreement, Purchaser agrees, immediately upon receipt of the stock
certificate(s) evidencing the Shares, to deliver such certificate(s), together
with the Stock Powers executed by Purchaser and by Purchaser's spouse, if any
(with the date and number of Shares left blank), to the Secretary of the Company
or other designee of the Company (the "ESCROW HOLDER"), who is hereby appointed
to hold such certificate(s) and Stock Powers in escrow and to take all such
actions and to effectuate all such transfers and/or releases of such Shares as
are in accordance with the terms of this Exercise Agreement. Purchaser and the
Company agree that Escrow Holder will not be liable to any party to this
Exercise Agreement (or to any other party) for any actions or omissions unless
Escrow Holder is grossly negligent or intentionally fraudulent in carrying out
the duties of Escrow Holder under this Exercise Agreement. Escrow Holder may
rely upon any letter, notice or other document executed with any signature
purported to be genuine and may rely on the advice of counsel and obey any order
of any court with respect to the transactions contemplated by this Exercise
Agreement. The Shares will be released from escrow upon termination both the
Repurchase Option and the Right of First Refusal; provided, however, that the
Shares will remain in escrow so long as they are subject to the Pledge
Agreement.

        12. RESTRICTIVE LEGENDS AND STOP-TRANSFER ORDERS.

                      UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
                      "SECURITIES ACT"), OR UNDER THE SECURITIES LAWS OF CERTAIN

                        PERMITTED UNDER THE SECURITIES ACT AND APPLICABLE STATE
                        SECURITIES LAWS, PURSUANT TO REGISTRATION OR EXEMPTION
                        THEREFROM. INVESTORS SHOULD BE AWARE THAT THEY MAY BE
                        REQUIRED TO BEAR THE FINANCIAL RISKS OF THIS INVESTMENT
                        FOR AN INDEFINITE PERIOD OF TIME. THE ISSUER OF THESE
                        SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND
                        SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT
                        ANY PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH
                        THE SECURITIES ACT AND ANY APPLICABLE STATE SECURITIES
                        LAWS.

                        THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
                        TO CERTAIN RESTRICTIONS ON PUBLIC RESALE AND TRANSFER,
                        INCLUDING THE RIGHT OF REPURCHASE AND RIGHT OF FIRST
                        REFUSAL OPTIONS HELD BY THE ISSUER AND/OR ITS
                        ASSIGNEE(S) AS SET FORTH IN A STOCK OPTION EXERCISE
                        AGREEMENT BETWEEN THE ISSUER AND THE ORIGINAL HOLDER OF
                        THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE
                        PRINCIPAL OFFICE OF THE ISSUER. SUCH PUBLIC SALE AND
                        TRANSFER RESTRICTIONS INCLUDING THE RIGHT OF REPURCHASE
                        AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES OF
                        THESE SHARES.

               12.2 Stop-Transfer Instructions. Purchaser agrees that, to ensure
compliance with the restrictions imposed by this Exercise Agreement, the Company
may issue appropriate "stop-transfer" instructions to its transfer agent, if
any, and if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

               12.3 Refusal to Transfer. The Company will not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Exercise Agreement or (ii) to treat
as owner of such Shares, or to accord the right to vote or pay dividends to any
purchaser or other transferee to whom such Shares have been so transferred.

      13. TAX CONSEQUENCES. PURCHASER UNDERSTANDS THAT PURCHASER MAY SUFFER
ADVERSE TAX CONSEQUENCES AS A RESULT OF PURCHASER'S PURCHASE OR DISPOSITION OF
THE SHARES. PURCHASER REPRESENTS: (i) THAT PURCHASER HAS CONSULTED WITH ANY TAX
ADVISER THAT PURCHASER DEEMS ADVISABLE IN CONNECTION WITH THE PURCHASE OR
DISPOSITION OF THE SHARES AND (ii) THAT PURCHASER IS NOT RELYING ON THE COMPANY
FOR ANY TAX ADVICE. IN PARTICULAR, IF UNVESTED SHARES ARE SUBJECT TO REPURCHASE
BY THE COMPANY, PURCHASER REPRESENTS THAT PURCHASER HAS CONSULTED WITH
PURCHASER'S OWN TAX ADVISER CONCERNING THE ADVISABILITY OF FILING AN 83(b)
ELECTION WITH THE INTERNAL REVENUE SERVICE WHICH MUST BE FILED WITHIN THIRTY
(30) DAYS OF THE PURCHASE OF SHARES TO BE EFFECTIVE.] Set forth below is a brief
summary as of the date the Plan was adopted by the Board of some of the U.S.
Federal and California tax consequences of exercise of the Option and
disposition of the



                                       10
<PAGE>   37

Shares. THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS
ARE SUBJECT TO CHANGE. PURCHASER SHOULD CONSULT HIS OR HER OWN TAX ADVISER
BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

               13.1 Exercise of Incentive Stock Option. If the Option qualifies
as an ISO, there will be no regular U.S. Federal income tax liability or
California income tax liability upon the exercise of the Option, although the
excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price will be treated as a tax preference item for U.S.
Federal alternative minimum tax purposes and may subject Purchaser to the
alternative minimum tax in the year of exercise.

               13.2 Exercise of Nonqualified Stock Option. If the Option does
not qualify as an ISO, there may be a regular U.S. Federal income tax liability
and a California income tax liability upon the exercise of the Option. Purchaser
will be treated as having received compensation income (taxable at ordinary
income tax rates) equal to the excess, if any, of the Fair Market Value of the
Shares on the date of exercise over the Exercise Price. If Purchaser is or was
an employee of the Company, the Company may be required to withhold from
Purchaser's compensation or collect from Purchaser and pay to the applicable
taxing authorities an amount equal to a percentage of this compensation income
at the time of exercise.

               13.3 Disposition of Shares. The following tax consequences may
apply upon disposition of the Shares.

                        (a) Incentive Stock Options. If the Shares are held for
more than twelve (12) months after the date of the transfer of the Shares
pursuant to the exercise of an ISO and are disposed of more than two (2) years
after the Date of Grant, any gain realized on disposition of the Shares will be
treated as long term capital gain for federal and California income tax
purposes. If Shares purchased under an ISO are disposed of within the applicable
one (1) year or two (2) year period, any gain realized on such disposition will
be treated as compensation income (taxable at ordinary income rates) to the
extent of the excess, if any, of the Fair Market Value of the Shares on the date
of exercise over the Exercise Price.

                        (b) Nonqualified Stock Options. If the Shares are held
for more than twelve (12) months after the date of the transfer of the Shares
pursuant to the exercise of an NQSO, any gain realized on disposition of the
Shares will be treated as long term capital gain.

                        (c) Withholding. The Company may be required to withhold
from the Purchaser's compensation or collect from the Purchaser and pay to the
applicable taxing authorities an amount equal to a percentage of this
compensation income.

               13.4 Section 83(b) Election for Unvested Shares. With respect to
Unvested Shares, which are subject to the Repurchase Option, unless an election
is filed by the Purchaser with the Internal Revenue Service (and, if necessary,
the proper state taxing authorities), WITHIN 30 DAYS OF THE PURCHASE of the
Unvested Shares, electing pursuant to Section 83(b) of the Code (and similar
state tax provisions, if applicable) to be taxed currently on any difference
between the Exercise Price of the Unvested Shares and their Fair Market Value on
the date of purchase, there may be a recognition of taxable income (including,
where applicable, alternative minimum



                                       11
<PAGE>   38

taxable income) to the Purchaser, measured by the excess, if any, of the Fair
Market Value of the Unvested Shares at the time they cease to be Unvested
Shares, over the Exercise Price of the Unvested Shares. A form of Election under
Section 83(b) is attached hereto as Exhibit [5] for reference.

      14. COMPLIANCE WITH LAWS AND REGULATIONS. The issuance and transfer of the
Shares will be subject to and conditioned upon compliance by the Company and
Purchaser with all applicable state and U.S. Federal laws and regulations and
with all applicable requirements of any stock exchange or automated quotation
system on which the Company's Common Stock may be listed or quoted at the time
of such issuance or transfer.

      15. SUCCESSORS AND ASSIGNS. The Company may assign any of its rights under
this Exercise Agreement, including its rights to purchase Shares under the
Repurchase Option and the Right of First Refusal. This Exercise Agreement shall
be binding upon and inure to the benefit of the successors and assigns of the
Company. Subject to the restrictions on transfer herein set forth, this Exercise
Agreement will be binding upon Purchaser and Purchaser's heirs, executors,
administrators, legal representatives, successors and assigns.

      16. GOVERNING LAW; SEVERABILITY. This Exercise Agreement shall be governed
by and construed in accordance with the internal laws of the State of California
as such laws are applied to agreements between California residents entered into
and to be performed entirely within California. If any provision of this
Exercise Agreement is determined by a court of law to be illegal or
unenforceable, then such provision will be enforced to the maximum extent
possible and the other provisions will remain fully effective and enforceable.

      17. NOTICES. Any notice required to be given or delivered to the Company
shall be in writing and addressed to the Corporate Secretary of the Company at
its principal corporate offices. Any notice required to be given or delivered to
Purchaser shall be in writing and addressed to Purchaser at the address
indicated above or to such other address as Purchaser may designate in writing
from time to time to the Company. All notices shall be deemed effectively given
upon personal delivery, (i) three (3) days after deposit in the United States
mail by certified or registered mail (return receipt requested), (ii) one (1)
business day after its deposit with any return receipt express courier
(prepaid), or (iii) one (1) business day after transmission by rapifax or
telecopier.

      18. FURTHER INSTRUMENTS. The parties agree to execute such further
instruments and to take such further action as may be reasonably necessary to
carry out the purposes and intent of this Exercise Agreement.

      19. HEADINGS. The captions and headings of this Exercise Agreement are
included for ease of reference only and will be disregarded in interpreting or
construing this Exercise Agreement. All references herein to Sections will refer
to Sections of this Exercise Agreement.

      20. ENTIRE AGREEMENT. The Plan, the Stock Option Agreement and this
Exercise Agreement, together with all Exhibits thereto, constitute the entire
agreement and understanding of the parties with respect to the subject matter of
this Exercise Agreement, and supersede all prior understandings and agreements,
whether oral or written, between the parties hereto with respect to the specific
subject matter hereof.

                             STOCK PLEDGE AGREEMENT


               This Stock Pledge Agreement (the "PLEDGE AGREEMENT") is made and
entered into as of _______________, _____ [INSERT DATE] between
_____________________________ [ADD COMPANY'S NAME], a California [DELAWARE]
corporation (the "COMPANY"), and _________________________ (the "PLEDGOR").
Capitalized terms that are not defined herein shall have the meanings ascribed
to them in the Secured Full Recourse Promissory Note of even date herewith
delivered by Pledgor to the Company (the "NOTE").

                                 R E C I T A L S

               A. In exchange for delivery of the Note to the Company, the
Company has issued and sold to Pledgor __________ shares of its Common Stock [IF
A DELAWARE CORPORATION ADD: $__________ [ADD PAR VALUE] PAR VALUE PER SHARE,]
(the "SHARES") pursuant to the terms and conditions of that certain Purchase
Agreement.

               B. Pledgor has agreed that repayment of the Note will be secured
by the pledge of the Shares pursuant to this Pledge Agreement [ADD IF
APPROPRIATE: AND BY CERTAIN OTHER COLLATERAL PURSUANT TO
______________________________ [DESCRIBE WRITTEN INSTRUMENTS HERE]].

               NOW, THEREFORE, the parties agree as follows:

               1. CREATION OF SECURITY INTEREST. Pursuant to the provisions of
the California Commercial Code, Pledgor hereby grants to the Company, and the
Company hereby accepts, a first and present security interest in (i) the Shares,
(ii) all Dividends (as defined in Section 5 hereof), [AND] (iii) all Additional
Securities (as defined in Section 6 hereof) [ADD IF APPROPRIATE: AND (IV)
______________________________ [DESCRIBE ADDITIONAL PERSONAL PROPERTY COLLATERAL
EITHER BY CATEGORY UNDER ARTICLE 9 OF THE UCC, E.G. FIXTURES, DEPOSIT ACCOUNTS,
ETC., OR WITH SUFFICIENT SPECIFICITY TO IDENTIFY SUCH COLLATERAL. DO NOT USE
"ALL PERSONAL PROPERTY" BECAUSE IT IS NOT SUFFICIENTLY SPECIFIC TO GRANT
SECURITY INTERESTS (COLLECTIVELY, THE "ADDITIONAL SECURITY")], to secure payment
of the Note and performance of all Pledgor's obligations under this Pledge
Agreement. Pledgor herewith delivers to the Company Common Stock certificate(s)
No(s). __________, [COMPLETE] representing all the Shares, together with one or
more stock power(s) for each certificate so delivered in the form attached as an
Exhibit to the Purchase Agreement, duly executed (with the date and number of
shares left blank) by Pledgor and Pledgor's spouse, if any. For purposes of this
Pledge Agreement, the Shares, all Dividends [, AND] all Additional Securities
[ADD IF APPLICABLE: AND ALL ADDITIONAL COLLATERAL] will hereinafter be
collectively referred to as the "COLLATERAL." Pledgor agrees that the Collateral
[IF ADDITIONAL COLLATERAL EXISTS, CONSIDER IF IT REQUIRES POSSESSION TO PERFECT,
E.G. IF IT IS OTHER SHARES OF STOCK OR A CERTIFICATE OF DEPOSIT (AN
"INSTRUMENT") FROM A BANK, ADD AND MODIFY ACCORDINGLY: WITH THE EXCEPTION OF
ADDITIONAL COLLATERAL,] will be deposited with and held by the Escrow Holder (as
defined in the Purchase Agreement) and that, notwithstanding anything to the
contrary in the Purchase Agreement, for purposes of carrying out the provisions
of this Pledge Agreement, Escrow Holder will act solely for the Company as its
agent.

                                       1
<PAGE>   51

               [IF ADDITIONAL COLLATERAL EXISTS, BE SURE THAT YOU HAVE PERFECTED
THE SECURITY INTEREST PROPERLY BY FILING OR TAKING POSSESSION, AS REQUIRED UNDER
ARTICLE 9 OF THE UCC OR UNDER THE COPYRIGHT ACT].

               2. REPRESENTATIONS AND WARRANTIES AND COVENANTS REGARDING
COLLATERAL. Pledgor hereby represents and warrants to the Company that Pledgor
has good title (both record and beneficial) to the Collateral, free and clear of
all claims, pledges, security interests, liens or encumbrances of every nature
whatsoever, and that Pledgor has the right to pledge and grant the Company the
security interest in the Collateral granted under this Pledge Agreement. Pledgor
further agrees that, until all sums due under the Note have been paid in full,
and all of Purchaser's obligations under this Pledge Agreement have been
performed, Purchaser will not, without the Company's prior written consent, (i)
sell, assign or transfer, or attempt to sell, assign or transfer, any of the
Collateral, or (ii) grant or create, or attempt to grant or create, any security
interest, lien, pledge, claim or other encumbrance with respect to any of the
Collateral or (iii) suffer or permit to continue upon any of the Collateral
during the term of this Pledge Agreement, an attachment, levy, execution or
statutory lien. [IF THERE IS ADDITIONAL COLLATERAL, PLEDGOR SHOULD AGREE TO
ADDITIONAL COVENANTS CONCERNING THE MAINTENANCE AND CONDITION OF THAT
COLLATERAL, E.G. INSURING AN AUTOMOBILE AGAINST LOSS, ETC.]

               3. RIGHTS ON DEFAULT. Upon an occurrence of an Event of Default
under the Note, the Company will have full power to sell, assign and deliver or
otherwise dispose the whole or any part of the Collateral at any broker's
exchange or elsewhere, at public or private sale, at the option of the Company,
in order to satisfy any part of the obligations of Pledgor now existing or
hereinafter arising under the Note or under this Pledge Agreement. On any such
sale, the Company or its assigns may purchase all or any part of the Collateral.
In addition, at its sole option, the Company may elect to retain all the
Collateral in full satisfaction of Pledgor's obligation under the Note, in
accordance with the provisions and procedures set forth in the California
Uniform Commercial Code. Pledgor agrees at the Company's request, to cooperate
with the Company in connection with the disposition of any and all of the
Collateral and to execute and deliver any documents which the Company shall
reasonably request to permit disposition of the Collateral.

               4. ADDITIONAL REMEDIES. The rights and remedies granted to the
Company herein upon an Event of Default will be in addition to all the rights,
powers and remedies of the Company under the California Uniform Commercial Code
and applicable law and such rights, powers and remedies will be exercisable by
the Company with respect to all of the Collateral. Pledgor agrees that the
Company's reasonable expenses of holding the Collateral, preparing it for resale
or other disposition, and selling or otherwise disposing of the Collateral,
including attorneys' fees and other legal expenses, will be deducted from the
proceeds of any sale or other disposition and will be included in the amounts
Pledgor must tender to redeem the Collateral. All rights, powers and remedies of
the Company will be cumulative and not alternative. Any forbearance or failure
or delay by the Company in exercising any right, power or remedy hereunder will
not be deemed to be a waiver of any such right, power or remedy and any single
or partial exercise of any such right, power or remedy hereunder will not
preclude the further exercise thereof.

                                       2
<PAGE>   52

               5. DIVIDENDS; VOTING. All dividends hereinafter declared on or
payable with respect to any Collateral during the term of this Pledge Agreement
(excluding only ordinary cash dividends, which will be payable to Pledgor so
long as no Event of Default has occurred under the Note) (the "DIVIDENDS") will
be immediately delivered to the Company to be held in pledge under this Pledge
Agreement. Notwithstanding this Pledge Agreement, so long as Pledgor owns the
Shares and no Event of Default has occurred under the Note, Pledgor will be
entitled to vote any shares comprising the Collateral, subject to any proxies
granted by Pledgor.

               6. ADJUSTMENTS. In the event that during the term of this Pledge
Agreement, any stock dividend, reclassification, readjustment, stock split or
other change is declared or made with respect to the Collateral, or if warrants
or any other rights, options or securities are issued in respect of the
Collateral, (the "ADDITIONAL SECURITIES") then all new, substituted and/or
additional shares or other securities issued by reason of such change or by
reason of the exercise of such warrants, rights, options or securities, will be
(if delivered to Pledgor, immediately surrendered to the Company and) pledged to
the Company to be held under the terms of this Pledge Agreement as and in the
same manner as the Collateral is held hereunder.

               7. RIGHTS UNDER PURCHASE AGREEMENT; SETOFF. Pledgor understands
and agrees that the Company's rights to repurchase the Collateral under the
Purchase Agreement, if any, will continue for the periods and on the terms and
conditions specified in the Purchase Agreement, whether or not the Note has been
paid in full during such period of time, and that to the extent that the Note is
not paid in full during such period of time, the repurchase by the Company of
the Collateral may be made by way of cancellation of all or any part of
Pledgor's indebtedness under the Note.

               8. REDELIVERY OF COLLATERAL; NO RELEASE FOR PARTIAL PAYMENT.

                        (a) Until all obligations of Pledgor under the Note and
under this Pledge Agreement have been satisfied in full, all Collateral will
continue to be held in pledge under this Pledge Agreement. If Pledgor prepays
all or a portion of the principal amount of the Note, the portion of the Shares
for which such pre-payment would represent the purchase price under the Purchase
Agreement (the "PAID SHARES") will be treated as independent collateral for the
remaining balance of the Note for the purpose of commencing the holding period
under Rule 144(d) of the Securities and Exchange Commission with respect to
other Shares purchased with the Note.

                        (b) Upon performance of all Pledgor's obligations under
the Note and this Pledge Agreement, and subject to the terms and conditions of
the Purchase Agreement, the Company will immediately redeliver the Collateral to
Pledgor and this Pledge Agreement will terminate; provided, however, that all
rights of the Company to retain possession of the Shares pursuant to the
Purchase Agreement will survive termination of this Pledge Agreement.

               9. FURTHER ASSURANCES. Pledgor shall, at the Company's request,
execute and deliver such further documents and take such further actions as the
Company shall reasonably request to perfect and maintain the Company's security
interest in the Collateral, or in any part thereof.

                                       3

               10. SUCCESSORS AND ASSIGNS. This Pledge Agreement will inure to
the benefit of the respective heirs, personal representatives, successors and
assigns of the parties hereto.

               11. GOVERNING LAW; SEVERABILITY. This Pledge Agreement will be
governed by and construed in accordance with the internal laws of the State of
California, excluding that body of law relating to conflicts of law. Should one
or more of the provisions of this Pledge Agreement be determined by a court of
law to be illegal or unenforceable, the other provisions nevertheless will
remain effective and will be enforceable.

               12. MODIFICATION; ENTIRE AGREEMENT. This Pledge Agreement will
not be amended without the written consent of both parties hereto. This Pledge
Agreement, together with the Note [ADD IF APPLICABLE: THE TRUST DEED, AND THE
UCC-1 FINANCING STATEMENTS [AND _________________________ ADD ANY ADDITIONAL
DOCUMENTS FILED WITH GOVERNMENTAL AUTHORITIES TO PERFECT THE SECURITY INTEREST,
IF APPLICABLE]] constitute the entire agreement of the parties hereto with
respect to the subject matter hereof and supersedes all prior agreements and
understandings related to such subject matter.


               IN WITNESS WHEREOF, the parties hereto have executed this Pledge
Agreement as of the date and year first above written.

                            BROADBASE SOFTWARE, INC.

                           1999 EQUITY INCENTIVE PLAN

                             As Adopted July 2, 1999



        1. PURPOSE. The purpose of this Plan is to provide incentives to
attract, retain and motivate eligible persons whose present and potential
contributions are important to the success of the Company, its Parent and
Subsidiaries, by offering them an opportunity to participate in the Company's
future performance through awards of Options, Restricted Stock and Stock
Bonuses. Capitalized terms not defined in the text are defined in Section 23.

        2. SHARES SUBJECT TO THE PLAN.

                2.1 Number of Shares Available. Subject to Sections 2.2 and 18,
the total number of Shares reserved and available for grant and issuance
pursuant to this Plan will be 3,500,000 Shares plus Shares that are subject to:
(a) issuance upon exercise of an Option but cease to be subject to such Option
for any reason other than exercise of such Option; (b) an Award granted
hereunder but are forfeited or are repurchased by the Company at the original
issue price; and (c) an Award that otherwise terminates without Shares being
issued. In addition, any authorized shares not issued or subject to outstanding
grants under the Broadbase Information Systems, Inc. 1996 Equity Incentive Plan
(the "PRIOR PLAN") on the Effective Date (as defined below) and any shares
issued under the Prior Plan that are forfeited or repurchased by the Company or
that are issuable upon exercise of options granted pursuant to the Prior Plan
that expire or become unexercisable for any reason without having been exercised
in full, will no longer be available for grant and issuance under the Prior
Plan, but will be available for grant and issuance under this Plan. In addition,
on December 31, 1999 and each anniversary thereafter, the aggregate number of
Shares reserved and available for grant and issuance pursuant to this Plan will
be increased automatically by a number of Shares equal to 5% of the total
outstanding shares of the Company as of the immediately preceding December 31,
provided that no more than 20,000,000 shares shall qualify as ISOs (as defined
in Section 5 below). At all times the Company shall reserve and keep available a
sufficient number of Shares as shall be required to satisfy the requirements of
all outstanding Options granted under this Plan and all other outstanding but
unvested Awards granted under this Plan.

                2.2 Adjustment of Shares. In the event that the number of
outstanding shares is changed by a stock dividend, recapitalization, stock
split, reverse stock split, subdivision, combination, reclassification or
similar change in the capital structure of the Company without consideration,
then (a) the number of Shares reserved for issuance under this Plan, (b) the
Exercise Prices of and number of Shares subject to outstanding Options, and (c)
the number of Shares subject to other outstanding Awards will be proportionately
adjusted, subject to any required action by the Board or the stockholders of the
Company and compliance with applicable securities laws; provided, however, that
fractions of a Share will not be issued but will either be replaced by a cash
payment equal to the Fair Market Value of such fraction of a Share or will be
rounded up to the nearest whole Share, as determined by the Committee.

        3. ELIGIBILITY. ISOs (as defined in Section 5 below) may be granted only
to employees (including officers and directors who are also employees) of the
Company or of a Parent or Subsidiary of the Company. All other Awards may be
granted to employees, officers, directors, consultants, independent contractors
and advisors of the Company or any Parent or Subsidiary of the Company; provided
such consultants, contractors and advisors render bona fide services not in
connection with the offer and sale of securities in a capital-raising
transaction. No person will be eligible to receive more than 2,000,000 Shares in
any calendar year under this Plan pursuant to the grant of Awards hereunder,
other than new employees of the Company or of a Parent or Subsidiary of the
Company (including new employees who are also officers and directors of the
Company or any Parent or Subsidiary of the Company), who are eligible to receive
up to a maximum of 3,000,000 Shares in the calendar year in which they commence
their employment. A person may be granted more than one Award under this Plan.

                other agreement or document executed pursuant to this Plan;

                other Awards under this Plan or any other incentive or

Directors pursuant to Section 9 hereof, any determination made by the Committee
with respect to any Award will be made in its sole discretion at the time of
grant of the Award or, unless in contravention of any express term of this Plan

the Company and on all persons having an interest in any Award under this Plan.
The Committee may delegate to one or more officers of the Company the authority
to grant an Award under this Plan to Participants who are not Insiders of the
Company.

        5. OPTIONS. The Committee may grant Options to eligible persons and will
determine whether such Options will be Incentive Stock Options within the
meaning of the Code ("ISO") or Nonqualified Stock Options ("NQSOS"), the number
of Shares subject to the Option, the Exercise Price of the Option, the period
during which the Option may be exercised, and all other terms and conditions of
the Option, subject to the following:

                5.1 Form of Option Grant. Each Option granted under this Plan
will be evidenced by an Award Agreement which will expressly identify the Option
as an ISO or an NQSO ("STOCK OPTION AGREEMENT"), and, except as otherwise
required by the terms of Section 9 hereof, will be in such form and contain such
provisions (which need not be the same for each Participant) as the Committee
may from time to time approve, and which will comply with and be subject to the
terms and conditions of this Plan.

                                                      1999 Equity Incentive Plan

                5.2 Date of Grant. The date of grant of an Option will be the
date on which the Committee makes the determination to grant such Option, unless
otherwise specified by the Committee. The Stock Option Agreement and a copy of
this Plan will be delivered to the Participant within a reasonable time after
the granting of the Option.

                5.3 Exercise Period. Options may be exercisable within the times
or upon the events determined by the Committee as set forth in the Stock Option
Agreement governing such Option; provided, however, that no Option will be
exercisable after the expiration of ten (10) years from the date the Option is
granted; and provided further that no ISO granted to a person who directly or by
attribution owns more than ten percent (10%) of the total combined voting power
of all classes of stock of the Company or of any Parent or Subsidiary of the
Company ("TEN PERCENT STOCKHOLDER") will be exercisable after the expiration of
five (5) years from the date the ISO is granted. The Committee also may provide
for Options to become exercisable at one time or from time to time, periodically
or otherwise, in such number of Shares or percentage of Shares as the Committee
determines.

                5.4 Exercise Price. The Exercise Price of an Option will be
determined by the Committee when the Option is granted and may be not less than
85% of the Fair Market Value of the Shares on the date of grant; provided that:
(i) the Exercise Price of an ISO will be not less than 100% of the Fair Market
Value of the Shares on the date of grant; and (ii) the Exercise Price of any ISO
granted to a Ten Percent Stockholder will not be less than 110% of the Fair
Market Value of the Shares on the date of grant. Payment for the Shares
purchased may be made in accordance with Section 8 of this Plan.

                5.5 Method of Exercise. Options may be exercised only by
delivery to the Company of a written stock option exercise agreement (the
"EXERCISE AGREEMENT") in a form approved by the Committee (which need not be the
same for each Participant), stating the number of Shares being purchased, the
restrictions imposed on the Shares purchased under such Exercise Agreement, if
any, and such representations and agreements regarding Participant's investment
intent and access to information and other matters, if any, as may be required
or desirable by the Company to comply with applicable securities laws, together
with payment in full of the Exercise Price for the number of Shares being
purchased.

                5.6 Termination. Notwithstanding the exercise periods set forth
in the Stock Option Agreement, exercise of an Option will always be subject to
the following:

        (a)     If the Participant is Terminated for any reason except death or
                Disability, then the Participant may exercise such Participant's
                Options only to the extent that such Options would have been
                exercisable upon the Termination Date no later than three (3)
                months after the Termination Date (or such shorter or longer
                time period not exceeding five (5) years as may be determined by
                the Committee, with any exercise beyond three (3) months after
                the Termination Date deemed to be an NQSO), but in any event, no
                later than the expiration date of the Options.

        (b)     If the Participant is Terminated because of Participant's death
                or Disability (or the Participant dies within three (3) months
                after a Termination other than for Cause or because of
                Participant's Disability), then Participant's Options may be
                exercised only to the extent that such Options would have been
                exercisable by Participant on the Termination Date and must be
                exercised by Participant (or Participant's legal representative
                or authorized assignee) no later than twelve (12) months after
                the Termination Date (or such shorter or longer time period not
                exceeding five (5) years as may be determined by the Committee,
                with any such exercise beyond (a) three (3) months after the
                Termination Date when the Termination is for any reason other
                than the Participant's death or Disability, or (b) twelve (12)
                months after the Termination Date when the Termination is for
                Participant's death or

                Disability, deemed to be an NQSO), but in any event no later
                than the expiration date of the Options.

        (c)     Notwithstanding the provisions in paragraph 5.6(a) above, if a
                Participant is terminated for Cause, neither the Participant,
                the Participant's estate nor such other person who may then hold
                the Option shall be entitled to exercise any Option with respect
                to any Shares whatsoever, after termination of service, whether
                or not after termination of service the Participant may receive
                payment from the Company or Subsidiary for vacation pay, for
                services rendered prior to termination, for services rendered
                for the day on which termination occurs, for salary in lieu of
                notice, or for any other benefits. In making such determination,
                the Board shall give the Participant an opportunity to present
                to the Board evidence on his behalf. For the purpose of this
                paragraph, termination of service shall be deemed to occur on
                the date when the Company dispatches notice or advice to the
                Participant that his service is terminated.

                5.7 Limitations on Exercise. The Committee may specify a
reasonable minimum number of Shares that may be purchased on any exercise of an
Option, provided that such minimum number will not prevent Participant from
exercising the Option for the full number of Shares for which it is then
exercisable.

                5.8 Limitations on ISO. The aggregate Fair Market Value
(determined as of the date of grant) of Shares with respect to which ISO are
exercisable for the first time by a Participant during any calendar year (under
this Plan or under any other incentive stock option plan of the Company, Parent
or Subsidiary of the Company) will not exceed $100,000. If the Fair Market Value
of Shares on the date of grant with respect to which ISO are exercisable for the
first time by a Participant during any calendar year exceeds $100,000, then the
Options for the first $100,000 worth of Shares to become exercisable in such
calendar year will be ISO and the Options for the amount in excess of $100,000
that become exercisable in that calendar year will be NQSOs. In the event that
the Code or the regulations promulgated thereunder are amended after the
Effective Date of this Plan to provide for a different limit on the Fair Market
Value of Shares permitted to be subject to ISO, such different limit will be
automatically incorporated herein and will apply to any Options granted after
the effective date of such amendment.

                5.9 Modification, Extension or Renewal. The Committee may
modify, extend or renew outstanding Options and authorize the grant of new
Options in substitution therefor, provided that any such action may not, without
the written consent of a Participant, impair any of such Participant's rights
under any Option previously granted. Any outstanding ISO that is modified,
extended, renewed or otherwise altered will be treated in accordance with
Section 424(h) of the Code. The Committee may reduce the Exercise Price of
outstanding Options without the consent of Participants affected by a written
notice to them; provided, however, that the Exercise Price may not be reduced
below the minimum Exercise Price that would be permitted under Section 5.4 of
this Plan for Options granted on the date the action is taken to reduce the
Exercise Price.

                5.10 No Disqualification. Notwithstanding any other provision in
this Plan, no term of this Plan relating to ISO will be interpreted, amended or
altered, nor will any discretion or authority granted under this Plan be
exercised, so as to disqualify this Plan under Section 422 of the Code or,
without the consent of the Participant affected, to disqualify any ISO under
Section 422 of the Code.

        6. RESTRICTED STOCK. A Restricted Stock Award is an offer by the Company
to sell to an eligible person Shares that are subject to restrictions. The
Committee will determine to whom an offer will be made, the number of Shares the
person may purchase, the price to be paid (the "PURCHASE PRICE"), the
restrictions to which the Shares will be subject, and all other terms and
conditions of the Restricted Stock Award, subject to the following:

                6.1 Form of Restricted Stock Award. All purchases under a
Restricted Stock Award made pursuant to this Plan will be evidenced by an Award
Agreement ("RESTRICTED STOCK PURCHASE AGREEMENT") that will be in such form
(which need not be the same for each Participant) as the Committee will from
time to time



                                       4

                                                        Broadbase Software, Inc.
                                                      1999 Equity Incentive Plan

approve, and will comply with and be subject to the terms and conditions of this
Plan. The offer of Restricted Stock will be accepted by the Participant's
execution and delivery of the Restricted Stock Purchase Agreement and full
payment for the Shares to the Company within thirty (30) days from the date the
Restricted Stock Purchase Agreement is delivered to the person. If such person
does not execute and deliver the Restricted Stock Purchase Agreement along with
full payment for the Shares to the Company within thirty (30) days, then the
offer will terminate, unless otherwise determined by the Committee.

                6.2 Purchase Price. The Purchase Price of Shares sold pursuant
to a Restricted Stock Award will be determined by the Committee on the date the
Restricted Stock Award is granted, except in the case of a sale to a Ten Percent
Stockholder, in which case the Purchase Price will be 100% of the Fair Market
Value. Payment of the Purchase Price may be made in accordance with Section 8 of
this Plan.

                6.3 Terms of Restricted Stock Awards. Restricted Stock Awards
shall be subject to such restrictions as the Committee may impose. These
restrictions may be based upon completion of a specified number of years of
service with the Company or upon completion of the performance goals as set out
in advance in the Participant's individual Restricted Stock Purchase Agreement.
Restricted Stock Awards may vary from Participant to Participant and between
groups of Participants. Prior to the grant of a Restricted Stock Award, the
Committee shall: (a) determine the nature, length and starting date of any
Performance Period for the Restricted Stock Award; (b) select from among the
Performance Factors to be used to measure performance goals, if any; and (c)
determine the number of Shares that may be awarded to the Participant. Prior to
the payment of any Restricted Stock Award, the Committee shall determine the
extent to which such Restricted Stock Award has been earned. Performance Periods
may overlap and Participants may participate simultaneously with respect to
Restricted Stock Awards that are subject to different Performance Periods and
having different performance goals and other criteria.

                6.4 Termination During Performance Period. If a Participant is
Terminated during a Performance Period for any reason, then such Participant
will be entitled to payment (whether in Shares, cash or otherwise) with respect
to the Restricted Stock Award only to the extent earned as of the date of
Termination in accordance with the Restricted Stock Purchase Agreement, unless
the Committee will determine otherwise.

        7. STOCK BONUSES.

                7.1 Awards of Stock Bonuses. A Stock Bonus is an award of Shares
(which may consist of Restricted Stock) for services rendered to the Company or
any Parent or Subsidiary of the Company. A Stock Bonus may be awarded for past
services already rendered to the Company, or any Parent or Subsidiary of the
Company pursuant to an Award Agreement (the "STOCK BONUS AGREEMENT") that will
be in such form (which need not be the same for each Participant) as the
Committee will from time to time approve, and will comply with and be subject to
the terms and conditions of this Plan. A Stock Bonus may be awarded upon
satisfaction of such performance goals as are set out in advance in the
Participant's individual Award Agreement (the "PERFORMANCE STOCK BONUS
AGREEMENT") that will be in such form (which need not be the same for each
Participant) as the Committee will from time to time approve, and will comply
with and be subject to the terms and conditions of this Plan. Stock Bonuses may
vary from Participant to Participant and between groups of Participants, and may
be based upon the achievement of the Company, Parent or Subsidiary and/or
individual performance factors or upon such other criteria as the Committee may
determine.

                7.2 Terms of Stock Bonuses. The Committee will determine the
number of Shares to be awarded to the Participant. If the Stock Bonus is being
earned upon the satisfaction of performance goals pursuant to a Performance
Stock Bonus Agreement, then the Committee will: (a) determine the nature, length
and starting date of any Performance Period for each Stock Bonus; (b) select
from among the Performance Factors to be used to measure the performance, if
any; and (c) determine the number of Shares that may be awarded to the
Participant. Prior to the payment of any Stock Bonus, the Committee shall
determine the extent to which such Stock Bonuses have been earned. Performance
Periods may overlap and Participants may participate simultaneously with respect
to Stock Bonuses that are subject to different Performance Periods and different
performance goals and other criteria. The number of Shares may be fixed or may
vary in accordance with such performance goals and


                                       5
<PAGE>   6

                                                        Broadbase Software, Inc.
                                                      1999 Equity Incentive Plan

criteria as may be determined by the Committee. The Committee may adjust the
performance goals applicable to the Stock Bonuses to take into account changes
in law and accounting or tax rules and to make such adjustments as the Committee
deems necessary or appropriate to reflect the impact of extraordinary or unusual
items, events or circumstances to avoid windfalls or hardships.

                7.3 Form of Payment. The earned portion of a Stock Bonus may be
paid currently or on a deferred basis with such interest or dividend equivalent,
if any, as the Committee may determine. Payment may be made in the form of cash
or whole Shares or a combination thereof, either in a lump sum payment or in
installments, all as the Committee will determine.

        8. PAYMENT FOR SHARE PURCHASES.

                8.1 Payment. Payment for Shares purchased pursuant to this Plan
may be made in cash (by check) or, where expressly approved for the Participant
by the Committee and where permitted by law:

        (a)     by cancellation of indebtedness of the Company to the
                Participant;

        (b)     by surrender of shares that either: (1) have been owned by
                Participant for more than six (6) months and have been paid for
                within the meaning of SEC Rule 144 (and, if such shares were
                purchased from the Company by use of a promissory note, such
                note has been fully paid with respect to such shares); or (2)
                were obtained by Participant in the public market;

        (c)     by tender of a full recourse promissory note having such terms
                as may be approved by the Committee and bearing interest at a
                rate sufficient to avoid imputation of income under Sections 483
                and 1274 of the Code; provided, however, that Participants who
                are not employees or directors of the Company will not be
                entitled to purchase Shares with a promissory note unless the
                note is adequately secured by collateral other than the Shares;

        (d)     by waiver of compensation due or accrued to the Participant for
                services rendered;

        (e)     with respect only to purchases upon exercise of an Option, and
                provided that a public market for the Company's stock exists:

                (1)     through a "same day sale" commitment from the
                        Participant and a broker-dealer that is a member of the
                        National Association of Securities Dealers (an "NASD
                        DEALER") whereby the Participant irrevocably elects to
                        exercise the Option and to sell a portion of the Shares
                        so purchased to pay for the Exercise Price, and whereby
                        the NASD Dealer irrevocably commits upon receipt of such
                        Shares to forward the Exercise Price directly to the
                        Company; or

                (2)     through a "margin" commitment from the Participant and a
                        NASD Dealer whereby the Participant irrevocably elects
                        to exercise the Option and to pledge the Shares so
                        purchased to the NASD Dealer in a margin account as
                        security for a loan from the NASD Dealer in the amount
                        of the Exercise Price, and whereby the NASD Dealer
                        irrevocably commits upon receipt of such Shares to
                        forward the Exercise Price directly to the Company; or

        (f)     by any combination of the foregoing.

                8.2 Loan Guarantees. The Committee may help the Participant pay
for Shares purchased under this Plan by authorizing a guarantee by the Company
of a third-party loan to the Participant.

        9. AUTOMATIC GRANTS TO OUTSIDE DIRECTORS.

                9.1 Types of Options and Shares. Options granted under this Plan
and subject to this Section 9 shall be NQSOs.

                9.2 Eligibility. Options subject to this Section 9 shall be
granted only to Outside Directors.

                9.3 Annual Grants. Each Outside Director who was a member of the
Board before the Effective Date will automatically be granted an Option for
10,000 Shares on the Effective Date, unless such Outside Director received a
grant of Options before the Effective Date. Each Outside Director who first
becomes a member of the Board on or after the Effective Date will automatically
be granted an Option for 10,000 Shares on the date such Outside Director first
becomes a member of the Board. Immediately following each annual meeting of
stockholders, all Outside Directors will automatically be granted an Option for
10,000 Shares, provided the Outside Director is a member of the Board on such
date and has served continuously as a member of the Board for a period of at
least one year since the date when such Outside Director first became a member
of the Board (the "ANNUAL GRANT").

                9.4 Vesting. Each Annual Grant shall be 100% vested and
immediately exercisable as of the date of grant.

                9.5 Exercise Price. The exercise price of an Annual Grant shall
be the Fair Market Value of the Shares, at the time that the Option is granted.

        10. WITHHOLDING TAXES.

                10.1 Withholding Generally. Whenever Shares are to be issued in
satisfaction of Awards granted under this Plan, the Company may require the
Participant to remit to the Company an amount sufficient to satisfy federal,
state and local withholding tax requirements prior to the delivery of any
certificate or certificates for such Shares. Whenever, under this Plan, payments
in satisfaction of Awards are to be made in cash, such payment will be net of an
amount sufficient to satisfy federal, state, and local withholding tax
requirements.

                10.2 Stock Withholding. When, under applicable tax laws, a
Participant incurs tax liability in connection with the exercise or vesting of
any Award that is subject to tax withholding and the Participant is obligated to
pay the Company the amount required to be withheld, the Committee may in its
sole discretion allow the Participant to satisfy the minimum withholding tax
obligation by electing to have the Company withhold from the Shares to be issued
that number of Shares having a Fair Market Value equal to the minimum amount
required to be withheld, determined on the date that the amount of tax to be
withheld is to be determined. All elections by a Participant to have Shares
withheld for this purpose will be made in accordance with the requirements
established by the Committee and be in writing in a form acceptable to the
Committee

        11. TRANSFERABILITY.

                11.1 Except as otherwise provided in this Section 11, Awards
granted under this Plan, and any interest therein, will not be transferable or
assignable by Participant, and may not be made subject to execution, attachment
or similar process, otherwise than by will or by the laws of descent and
distribution or as determined by the Committee and set forth in the Award
Agreement with respect to Awards that are not ISOs.

                11.2 All Awards other than NQSO's. All Awards other than NQSO's
shall be exercisable: (i) during the Participant's lifetime, only by (A) the
Participant, or (B) the Participant's guardian or legal representative; and (ii)
after Participant's death, by the legal representative of the Participant's
heirs or legatees.



                                       7

                                                      1999 Equity Incentive Plan

                11.3 NQSOs. Unless otherwise restricted by the Committee, an
NQSO shall be exercisable: (i) during the Participant's lifetime only by (A) the
Participant, (B) the Participant's guardian or legal representative, (C) a
Family Member of the Participant who has acquired the NQSO by "permitted
transfer;" and (ii) after Participant's death, by the legal representative of
the Participant's heirs or legatees. "Permitted transfer" means, as authorized
by this Plan and the Committee in an NQSO, any transfer effected by the
Participant during the Participant's lifetime of an interest in such NQSO but
only such transfers which are by gift or domestic relations order. A permitted
transfer does not include any transfer for value and neither of the following
are transfers for value: (a) a transfer of under a domestic relations order in
settlement of marital property rights or (b) a transfer to an entity in which
more than fifty percent of the voting interests are owned by Family Members or
the Participant in exchange for an interest in that entity.

        12. PRIVILEGES OF STOCK OWNERSHIP; RESTRICTIONS ON SHARES..

                12.1 Voting and Dividends. No Participant will have any of the
rights of a stockholder with respect to any Shares until the Shares are issued
to the Participant. After Shares are issued to the Participant, the Participant
will be a stockholder and have all the rights of a stockholder with respect to
such Shares, including the right to vote and receive all dividends or other
distributions made or paid with respect to such Shares; provided, that if such
Shares are Restricted Stock, then any new, additional or different securities
the Participant may become entitled to receive with respect to such Shares by
virtue of a stock dividend, stock split or any other change in the corporate or
capital structure of the Company will be subject to the same restrictions as the
Restricted Stock; provided, further, that the Participant will have no right to
retain such stock dividends or stock distributions with respect to Shares that
are repurchased at the Participant's Purchase Price or Exercise Price pursuant
to Section 12.

                12.2 Financial Statements. The Company will provide financial
statements to each Participant prior to such Participant's purchase of Shares
under this Plan, and to each Participant annually during the period such
Participant has Awards outstanding; provided, however, the Company will not be
required to provide such financial statements to Participants whose services in
connection with the Company assure them access to equivalent information.

                12.3 Restrictions on Shares. At the discretion of the Committee,
the Company may reserve to itself and/or its assignee(s) in the Award Agreement
a right to repurchase a portion of or all Unvested Shares held by a Participant
following such Participant's Termination at any time within ninety (90) days
after the later of Participant's Termination Date and the date Participant
purchases Shares under this Plan, for cash and/or cancellation of purchase money
indebtedness, at the Participant's Exercise Price or Purchase Price, as the case
may be.

        13. CERTIFICATES. All certificates for Shares or other securities
delivered under this Plan will be subject to such stock transfer orders, legends
and other restrictions as the Committee may deem necessary or advisable,
including restrictions under any applicable federal, state or foreign securities
law, or any rules, regulations and other requirements of the SEC or any stock
exchange or automated quotation system upon which the Shares may be listed or
quoted.

        14. ESCROW; PLEDGE OF SHARES. To enforce any restrictions on a
Participant's Shares, the Committee may require the Participant to deposit all
certificates representing Shares, together with stock powers or other
instruments of transfer approved by the Committee, appropriately endorsed in
blank, with the Company or an agent designated by the Company to hold in escrow
until such restrictions have lapsed or terminated, and the Committee may cause a
legend or legends referencing such restrictions to be placed on the
certificates. Any Participant who is permitted to execute a promissory note as
partial or full consideration for the purchase of Shares under this Plan will be
required to pledge and deposit with the Company all or part of the Shares so
purchased as collateral to secure



                                       8
<PAGE>   9

                                                        Broadbase Software, Inc.
                                                      1999 Equity Incentive Plan

the payment of Participant's obligation to the Company under the promissory
note; provided, however, that the Committee may require or accept other or
additional forms of collateral to secure the payment of such obligation and, in
any event, the Company will have full recourse against the Participant under the
promissory note notwithstanding any pledge of the Participant's Shares or other
collateral. In connection with any pledge of the Shares, Participant will be
required to execute and deliver a written pledge agreement in such form as the
Committee will from time to time approve. The Shares purchased with the
promissory note may be released from the pledge on a pro rata basis as the
promissory note is paid. Notwithstanding the foregoing, only Shares that have
been pledged as provided above and/or that are Unvested Shares shall be held in
escrow.

        15. EXCHANGE AND BUYOUT OF AWARDS. The Committee may, at any time or
from time to time, authorize the Company, with the consent of the respective
Participants, to issue new Awards in exchange for the surrender and cancellation
of any or all outstanding Awards. The Committee may at any time buy from a
Participant an Award previously granted with payment in cash, Shares (including
Restricted Stock) or other consideration, based on such terms and conditions as
the Committee and the Participant may agree.

        16. SECURITIES LAW AND OTHER REGULATORY COMPLIANCE. An Award will not be
effective unless such Award is in compliance with all applicable federal and
state securities laws, rules and regulations of any governmental body, and the
requirements of any stock exchange or automated quotation system upon which the
Shares may then be listed or quoted, as they are in effect on the date of grant
of the Award and also on the date of exercise or other issuance. Notwithstanding
any other provision in this Plan, the Company will have no obligation to issue
or deliver certificates for Shares under this Plan prior to: (a) obtaining any
approvals from governmental agencies that the Company determines are necessary
or advisable; and/or (b) completion of any registration or other qualification
of such Shares under any state or federal law or ruling of any governmental body
that the Company determines to be necessary or advisable. The Company will be
under no obligation to register the Shares with the SEC or to effect compliance
with the registration, qualification or listing requirements of any state
securities laws, stock exchange or automated quotation system, and the Company
will have no liability for any inability or failure to do so.

        17. NO OBLIGATION TO EMPLOY. Nothing in this Plan or any Award granted
under this Plan will 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 Parent or Subsidiary of the Company or limit in any way the right
of the Company or any Parent or Subsidiary of the Company to terminate
Participant's employment or other relationship at any time, with or without
cause.

        18. CORPORATE TRANSACTIONS.

                18.1 Assumption or Replacement of Awards by Successor. In the
event of (a) a dissolution or liquidation of the Company, (b) a merger or
consolidation in which the Company is not the surviving corporation (other than
a merger or consolidation with a wholly-owned subsidiary, a reincorporation of
the Company in a different jurisdiction, or other transaction in which there is
no substantial change in the stockholders of the Company or their relative stock
holdings and the Awards granted under this Plan are assumed, converted or
replaced by the successor corporation, which assumption will be binding on all
Participants), (c) a merger in which the Company is the surviving corporation
but after which the stockholders of the Company immediately prior to such merger
(other than any stockholder that merges, or which owns or controls another
corporation that merges, with the Company in such merger) cease to own their
shares or other equity interest in the Company, (d) the sale of substantially
all of the assets of the Company, or (e) the acquisition, sale, or transfer of
more than 50% of the outstanding shares of the Company by tender offer or
similar transaction, any or all outstanding Awards may be assumed, converted or
replaced by the successor corporation (if any), which assumption, conversion or
replacement will be binding on all Participants. In the alternative, the
successor corporation may substitute equivalent Awards or provide substantially
similar consideration to Participants as was provided to stockholders (after
taking into account the existing provisions of the Awards). The successor
corporation may also issue, in place of outstanding Shares of the Company held
by the Participants, substantially similar shares or other property subject to
repurchase restrictions no less favorable to the Participant. In the event such
successor corporation (if any) refuses to assume or substitute Awards, as
provided above, pursuant to a transaction described in this Subsection 18.1,
such Awards will expire on such transaction at such time and on such conditions
as the Committee will determine. [Notwithstanding

                                                        Broadbase Software, Inc.
                                                      1999 Equity Incentive Plan

anything in this Plan to the contrary, the Committee may, in its sole discretion
and only on or after the date on which the registration statement filed by the
Company with the SEC under the Securities Act registering the initial public
offering of the Company's Common Stock is declared effective by the SEC, provide
that the vesting of any or all Awards granted pursuant to this Plan will
accelerate upon a transaction described in this Section 18. If the Committee
exercises such discretion with respect to Options, such Options will become
exercisable in full prior to the consummation of such event at such time and on
such conditions as the Committee determines, and if such Options are not
exercised prior to the consummation of the corporate transaction, they shall
terminate at such time as determined by the Committee.

                18.2 Other Treatment of Awards. Subject to any greater rights
granted to Participants under the foregoing provisions of this Section 18, in
the event of the occurrence of any transaction described in Section 18.1, any
outstanding Awards will be treated as provided in the applicable agreement or
plan of merger, consolidation, dissolution, liquidation, or sale of assets.

                18.3 Assumption of Awards by the Company. The Company, from time
to time, also may substitute or assume outstanding awards granted by another
company, whether in connection with an acquisition of such other company or
otherwise, by either; (a) granting an Award under this Plan in substitution of
such other company's award; or (b) assuming such award as if it had been granted
under this Plan if the terms of such assumed award could be applied to an Award
granted under this Plan. Such substitution or assumption will be permissible if
the holder of the substituted or assumed award would have been eligible to be
granted an Award under this Plan if the other company had applied the rules of
this Plan to such grant. In the event the Company assumes an award granted by
another company, the terms and conditions of such award will remain unchanged
(except that the exercise price and the number and nature of Shares issuable
upon exercise of any such option will be adjusted appropriately pursuant to
Section 424(a) of the Code). In the event the Company elects to grant a new
Option rather than assuming an existing option, such new Option may be granted
with a similarly adjusted Exercise Price.

        19. ADOPTION AND STOCKHOLDER APPROVAL. This Plan will become effective
on the date on which the registration statement filed by the Company with the
SEC under the Securities Act registering the initial public offering of the
Company's Common Stock is declared effective by the SEC (the "EFFECTIVE DATE").
This Plan shall be approved by the stockholders of the Company (excluding Shares
issued pursuant to this Plan), consistent with applicable laws, within twelve
(12) months before or after the date this Plan is adopted by the Board. Upon the
Effective Date, the Committee may grant Awards pursuant to this Plan; provided,
however, that: (a) no Option may be exercised prior to initial stockholder
approval of this Plan; (b) no Option granted pursuant to an increase in the
number of Shares subject to this Plan approved by the Board will be exercised
prior to the time such increase has been approved by the stockholders of the
Company; (c) in the event that initial stockholder approval is not obtained
within the time period provided herein, all Awards granted hereunder shall be
cancelled, any Shares issued pursuant to any Awards shall be cancelled and any
purchase of Shares issued hereunder shall be rescinded; and (d) in the event
that stockholder approval of such increase is not obtained within the time
period provided herein, all Awards granted pursuant to such increase will be
cancelled, any Shares issued pursuant to any Award granted pursuant to such
increase will be cancelled, and any purchase of Shares pursuant to such increase
will be rescinded.

        20. TERM OF PLAN/GOVERNING LAW. Unless earlier terminated as provided
herein, this Plan will terminate ten (10) years from the date this Plan is
adopted by the Board or, if earlier, the date of stockholder approval. This Plan
and all agreements thereunder shall be governed by and construed in accordance
with the laws of the State of California.

        21. AMENDMENT OR TERMINATION OF PLAN. The Board may at any time
terminate or amend this Plan in any respect, including without limitation
amendment of any form of Award Agreement or instrument to be executed pursuant
to this Plan; provided, however, that the Board will not, without the approval
of the stockholders of the Company, amend this Plan in any manner that requires
such stockholder approval.

        22. NONEXCLUSIVITY OF THE PLAN. Neither the adoption of this Plan by the
Board, the submission of this Plan to the stockholders of the Company for
approval, nor any provision of this Plan will be construed as creating any
limitations on the power of the Board to adopt such additional compensation
arrangements as it may deem desirable, including, without limitation, the
granting of stock options and bonuses otherwise than under this Plan, and such
arrangements may be either generally applicable or applicable only in specific
cases.

the Shares; and (c) thereafter this Option shall become exercisable as to an

Optionee shall in no event be entitled under this Option to purchase a number of
shares of the Company's Common Stock greater than the "Total Option Shares."

               2.2 Vesting of Options. Shares that are vested pursuant to the
schedule set forth in Section 2.1 hereof are "Vested Shares." Shares that are
not vested pursuant to the schedule set forth in Section 2.1 hereof are

               2.3 Expiration. This Option shall expire on the Expiration Date

Disability), then this Option, to the extent that it is vested in accordance
with the schedule set forth in Section 2.1 hereof on the Termination Date, may
be exercised by Optionee (or Optionee's legal representative or authorized
assignee) no later than twelve (12) months after the Termination Date, but in
any event no later than the Expiration Date. Any exercise after three months
after the Termination Date when the Termination is for any reason other than
Optionee's death or disability, within the meaning of Code Section 22(e)(3),
shall be deemed to be the exercise of a nonqualified stock option.

               3.3 Termination for Cause. If Optionee is Terminated for Cause,
this Option will expire on the Optionee's date of Termination.

               3.4 No Obligation to Employ. Nothing in the Plan or this
Agreement shall confer on Optionee any right to continue in the employ of, or
other relationship with, the Company or any Parent or Subsidiary of the Company,
or limit in any way the right of the Company or any Parent or Subsidiary of the
Company to terminate Optionee's employment or other relationship at any time,
with or without Cause.

hereto as Exhibit A, or in such other form as may be approved by the Company
from time to time (the "EXERCISE AGREEMENT"), which shall set forth, inter alia,
Optionee's election to exercise this Option, the number of shares being
purchased, any restrictions imposed on the Shares and any representations,
warranties and agreements regarding Optionee's investment intent and access to
information as may be required by the Company to comply with applicable
securities laws. If someone other than Optionee exercises this Option, then such
person must submit documentation reasonably acceptable to the Company that such
person has the right to exercise this Option.

               4.2 Limitations on Exercise. This Option may not be exercised
unless such exercise is in compliance with all applicable federal and state
securities laws, as they are in effect on the date of exercise. This Option may
not be exercised as to fewer than 100 Shares unless it is exercised as to all
Shares as to which this Option is then exercisable.

               4.3 Payment. The Exercise Agreement shall be accompanied by full
payment of the Exercise Price for the Shares being purchased in cash (by check),
or where permitted by law:

        (a)     by surrender of shares of the Company's Common Stock that
                either: (1) have been owned by Optionee for more than six (6)
                months and have been paid for within the meaning of SEC Rule 144
                (and, if such shares were purchased from the Company by use of a
                promissory note, such note has been fully paid with respect to
                such shares); or (2) were obtained by Optionee in the open
                public market; and (3) are clear of all liens, claims,
                encumbrances or security interests;

        (b)     provided that a public market for the Company's stock exists:
                (1) through a "same day sale" commitment from Optionee and a
                broker-dealer that is a member of the National Association of
                Securities Dealers (an "NASD DEALER") whereby Optionee
                irrevocably elects to exercise this Option and to sell a portion
                of the Shares so purchased to pay for the Exercise Price and
                whereby the NASD Dealer irrevocably commits upon receipt of such
                Shares to forward the exercise price directly to the Company; or
                (2) through a "margin" commitment from Optionee and an NASD
                Dealer whereby Optionee irrevocably elects to exercise this
                Option and to pledge the Shares so purchased to the NASD Dealer
                in a margin account as security for a loan from the NASD Dealer
                in the amount of the Exercise Price, and whereby the NASD Dealer
                irrevocably commits upon receipt of such Shares to forward the
                Exercise Price directly to the Company;

        (c)     by any combination of the foregoing.

                                                      1999 Equity Incentive Plan

               4.4 Tax Withholding. Prior to the issuance of the Shares upon
exercise of this Option, Optionee must pay or provide for any applicable federal
or state withholding obligations of the Company. If the Committee permits,
Optionee may provide for payment of withholding taxes upon exercise of this
Option by requesting that the Company retain Shares with a Fair Market Value
equal to the minimum amount of taxes required to be withheld. In such case, the
Company shall issue the net number of Shares to the Optionee by deducting the
Shares retained from the Shares issuable upon exercise.

               4.5 Issuance of Shares. Provided that the Exercise Agreement and
payment are in form and substance satisfactory to counsel for the Company, the
Company shall issue the Shares registered in the name of Optionee, Optionee's
authorized assignee, or Optionee's legal representative, and shall deliver
certificates representing the Shares with the appropriate legends affixed
thereto.

        5. NOTICE OF DISQUALIFYING DISPOSITION OF ISO SHARES. To the extent this
Option is an ISO, if Optionee sells or otherwise disposes of any of the Shares
acquired pursuant to the ISO on or before the later of (a) the date two (2)
years after the Date of Grant, and (b) the date one (1) year after transfer of
such Shares to Optionee upon exercise of this Option, then Optionee shall
immediately notify the Company in writing of such disposition.

        6. COMPLIANCE WITH LAWS AND REGULATIONS. The exercise of this Option and
the issuance and transfer of Shares shall be subject to compliance by the
Company and Optionee with all applicable requirements of federal and state
securities laws and with all applicable requirements of any stock exchange on
which the Company's Common Stock may be listed at the time of such issuance or
transfer. Optionee understands that the Company is under no obligation to
register or qualify the Shares with the SEC, any state securities commission or
any stock exchange to effect such compliance.

        7. NONTRANSFERABILITY OF OPTION. This Option may not be transferred in
any manner other than by will or by the laws of descent and distribution and may
be exercised during the lifetime of Optionee only by Optionee. The terms of this
Option shall be binding upon the executors, administrators, successors and
assigns of Optionee.

        8. TAX CONSEQUENCES. Set forth below is a brief summary as of the date
the Board adopted the Plan of some of the federal tax consequences of exercise
of this Option and disposition of the Shares. THIS SUMMARY IS NECESSARILY
INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE. OPTIONEE
SHOULD CONSULT A TAX ADVISOR BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE
SHARES.

               8.1 Exercise of Incentive Stock Option. To the extent this Option
qualifies as an ISO, there will be no regular federal income tax liability upon
the exercise of this Option, although the excess, if any, of the fair market
value of the Shares on the date of exercise


                                       4


<PAGE>   18
over the Exercise Price will be treated as a tax preference item for federal
income tax purposes and may subject the Optionee to the alternative minimum tax
in the year of exercise.

               8.2 Exercise of Nonqualified Stock Option. To the extent this
Option does not qualify as an ISO, there may be a regular federal income tax
liability upon the exercise of this Option. Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the fair market value of the Shares on the date of exercise
over the Exercise Price. The Company may be required to withhold from Optionee's
compensation or collect from Optionee and pay to the applicable taxing
authorities an amount equal to a percentage of this compensation income at the
time of exercise.

               8.3 Disposition of Shares. The following tax consequences may
apply upon disposition of the Shares.

                      a. Incentive Stock Options. If the Shares are held for
more than twelve (12) months after the date of the transfer of the Shares
pursuant to the exercise of an ISO and are disposed of more than two (2) years
after the Date of Grant, any gain realized on disposition of the Shares will be
treated as capital gain for federal income tax purposes. If Shares purchased
under an ISO are disposed of within the applicable one (1) year or two (2) year
period, any gain realized on such disposition will be treated as compensation
income (taxable at ordinary income rates) to the extent of the excess, if any,
of the fair market value of the Shares on the date of exercise over the Exercise
Price.

                      b. Nonqualified Stock Options. If the Shares are held for
more than twelve (12) months after the date of the transfer of the Shares
pursuant to the exercise of an NQSO, any gain realized on disposition of the
Shares will be treated as long-term capital gain.

                      c. Withholding. The Company may be required to withhold
from Participant's compensation or collect from the Participant and pay to the
applicable taxing authorities an amount equal to a percentage of this
compensation income.

        9. PRIVILEGES OF STOCK OWNERSHIP. Optionee shall not have any of the
rights of a stockholder with respect to any Shares until the Shares are issued
to Optionee.

        10. INTERPRETATION. Any dispute regarding the interpretation of this
Agreement shall be submitted by Optionee or the Company to the Committee for
review. The resolution of such a dispute by the Committee shall be final and
binding on the Company and Optionee.

        11. ENTIRE AGREEMENT. The Plan is incorporated herein by reference. This
Agreement and the Plan and the Exercise Agreement constitute the entire
agreement and understanding of the parties hereto with respect to the subject
matter hereof and supersede all prior understandings and agreements with respect
to such subject matter.

        12. NOTICES. Any notice required to be given or delivered to the Company
under the terms of this Agreement shall be in writing and addressed to the
Corporate Secretary of

        13. SUCCESSORS AND ASSIGNS. The Company may assign any of its rights
under this Agreement. This Agreement shall be binding upon and inure to the
benefit of the successors and assigns of the Company. Subject to the
restrictions on transfer set forth herein, this Agreement shall be binding upon
Optionee and Optionee's heirs, executors, administrators, legal representatives,
successors and assigns.

        14. GOVERNING LAW. This Agreement shall be governed by and construed in
accordance with the internal laws of the State of California, without regard to
that body of law pertaining to choice of law or conflict of law.

Plan and this Agreement. Optionee has read and understands the terms and
provisions thereof, and accepts this Option subject to all the terms and

Shares and that the Company has advised Optionee to consult a tax advisor prior

                            BROADBASE SOFTWARE, INC.
                        1999 EMPLOYEE STOCK PURCHASE PLAN

                             As Adopted July 2, 1999



        1. ESTABLISHMENT OF PLAN. Broadbase Software, Inc. (the "COMPANY")
proposes to grant options for purchase of the Company's Common Stock to eligible
employees of the Company and its Participating Subsidiaries (as hereinafter
defined) pursuant to this Employee Stock Purchase Plan (this "PLAN"). For
purposes of this Plan, "PARENT CORPORATION" and "SUBSIDIARY" shall have the same
meanings as "parent corporation" and "subsidiary corporation" in Sections 424(e)
and 424(f), respectively, of the Internal Revenue Code of 1986, as amended (the
"CODE"). "PARTICIPATING SUBSIDIARIES" are Parent Corporations or Subsidiaries
that the Board of Directors of the Company (the "BOARD") designates from time to
time as corporations that shall participate in this Plan. The Company intends
this Plan to qualify as an "employee stock purchase plan" under Section 423 of
the Code (including any amendments to or replacements of such Section), and this
Plan shall be so construed. Any term not expressly defined in this Plan but
defined for purposes of Section 423 of the Code shall have the same definition
herein. A total of 500,000 shares of the Company's Common Stock is reserved for
issuance under this Plan. In addition, on each January 1, the aggregate number
of shares of the Company's Common Stock reserved for issuance under the Plan
shall be increased automatically by a number of shares equal to 1% of the total
number of outstanding shares of the Company Common Stock on the immediately
preceding December 31; provided that the aggregate number of shares issued over
the term of this Plan shall not exceed 5,000,000 shares. Such number shall be
subject to adjustments effected in accordance with Section 14 of this Plan.

        2. PURPOSE. The purpose of this Plan is to provide eligible employees of
the Company and Participating Subsidiaries with a convenient means of acquiring
an equity interest in the Company through payroll deductions, to enhance such
employees' sense of participation in the affairs of the Company and
Participating Subsidiaries, and to provide an incentive for continued
employment.

        3. ADMINISTRATION. This Plan shall be administered by the Compensation
Committee of the Board (the "COMMITTEE"). Subject to the provisions of this Plan
and the limitations of Section 423 of the Code or any successor provision in the
Code, all questions of interpretation or application of this Plan shall be
determined by the Committee and its decisions shall be final and binding upon
all participants. Members of the Committee shall receive no compensation for
their services in connection with the administration of this Plan, other than
standard fees as established from time to time by the Board for services
rendered by Board members serving on Board committees. All expenses incurred in
connection with the administration of this Plan shall be paid by the Company.

        4. ELIGIBILITY. Any employee of the Company or the Participating
Subsidiaries is eligible to participate in an Offering Period (as hereinafter
defined) under this Plan except the following:

            (a) employees who are not employed by the Company or a Participating
Subsidiary (10) days before the beginning of such Offering Period, except that
employees who are employed on the Effective Date of the Registration Statement
filed by the Company with the Securities and Exchange Commission ("SEC") under
the Securities Act of 1933, as amended (the "SECURITIES ACT") registering the
initial public offering of the Company's Common Stock shall be eligible to
participate in the first Offering Period under the Plan;

            (b) employees who are customarily employed for twenty (20) hours or
less per week;

            (c) employees who are customarily employed for five (5) months or
less in a calendar year;

            (d) employees who, together with any other person whose stock would
be attributed to such employee pursuant to Section 424(d) of the Code, own stock
or hold options to purchase stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Company or
any of its Participating Subsidiaries or who, as a result of being granted an
option under this Plan with respect to such Offering Period, would own stock or
hold options to purchase stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of stock of the Company or any of
its Participating Subsidiaries; and

                                               1999 Employee Stock Purchase Plan


          (e) individuals who provide services to the Company or any of its
Participating Subsidiaries as independent contractors who are reclassified as
common law employees for any reason except for federal income and employment tax
purposes.

        5. OFFERING DATES. The offering periods of this Plan (each, an "OFFERING
PERIOD") shall be of twenty-four (24) months duration commencing on February 1
and August 1 of each year and ending on January 31 and July 31 of each year;
provided, however, that notwithstanding the foregoing, the first such Offering
Period shall commence on the first business day on which price quotations for
the Company's Common Stock are available on the Nasdaq National Market (the
"FIRST OFFERING DATE") and shall end on July 31, 2001. Except for the first
Offering Period, each Offering Period shall consist of four (4) six month
purchase periods (individually, a "PURCHASE PERIOD") during which payroll
deductions of the participants are accumulated under this Plan. The first
Offering Period shall consist of no more than five and no fewer than three
Purchase Periods, any of which may be greater or less than six months as
determined by the Committee. The first business day of each Offering Period is
referred to as the "OFFERING DATE". The last business day of each Purchase
Period is referred to as the "PURCHASE DATE". The Committee shall have the power
to change the duration of Offering Periods with respect to offerings without
stockholder approval if such change is announced at least fifteen (15) days
prior to the scheduled beginning of the first Offering Period to be affected.

        6. PARTICIPATION IN THIS PLAN. Eligible employees may become
participants in an Offering Period under this Plan on the first Offering Date
after satisfying the eligibility requirements by delivering a subscription
agreement to the Company's treasury department (the "TREASURY Department") not
later than five (5) days before such Offering Date. Notwithstanding the
foregoing, the Committee may set a later time for filing the subscription
agreement authorizing payroll deductions for all eligible employees with respect
to a given Offering Period. An eligible employee who does not deliver a
subscription agreement to the Treasury Department by such date after becoming
eligible to participate in such Offering Period shall not participate in that
Offering Period or any subsequent Offering Period unless such employee enrolls
in this Plan by filing a subscription agreement with the Treasury Department not
later than five (5) days preceding a subsequent Offering Date. Once an employee
becomes a participant in an Offering Period, such employee will automatically
participate in the Offering Period commencing immediately following the last day
of the prior Offering Period unless the employee withdraws or is deemed to
withdraw from this Plan or terminates further participation in the Offering
Period as set forth in Section 11 below. Such participant is not required to
file any additional subscription agreement in order to continue participation in
this Plan.

        7. GRANT OF OPTION ON ENROLLMENT. Enrollment by an eligible employee in
this Plan with respect to an Offering Period will constitute the grant (as of
the Offering Date) by the Company to such employee of an option to purchase on
the Purchase Date up to that number of shares of Common Stock of the Company
determined by dividing (a) the amount accumulated in such employee's payroll
deduction account during such Purchase Period by (b) the lower of (i)
eighty-five percent (85%) of the fair market value of a share of the Company's
Common Stock on the Offering Date (but in no event less than the par value of a
share of the Company's Common Stock), or (ii) eighty-five percent (85%) of the
fair market value of a share of the Company's Common Stock on the Purchase Date
(but in no event less than the par value of a share of the Company's Common
Stock), provided, however, that the number of shares of the Company's Common
Stock subject to any option granted pursuant to this Plan shall not exceed the
lesser of (x) the maximum number of shares set by the Committee pursuant to
Section 10(c) below with respect to the applicable Purchase Date, or (y) the
maximum number of shares which may be purchased pursuant to Section 10(b) below
with respect to the applicable Purchase Date. The fair market value of a share
of the Company's Common Stock shall be determined as provided in Section 8
below.

        8. PURCHASE PRICE. The purchase price per share at which a share of
Common Stock will be sold in any Offering Period shall be eighty-five percent
(85%) of the lesser of:

          (a)  The fair market value on the Offering Date; or

          (b) The fair market value on the Purchase Date.

          For purposes of this Plan, the term "FAIR MARKET VALUE" means, as of
any date, the value of a share of the Company's Common Stock determined as
follows:

             (a)     if such Common Stock is then quoted on the Nasdaq National
                     Market, its closing price on the Nasdaq National Market on
                     the date of determination as reported in The Wall Street
                     Journal;

             (b)     if such Common Stock is publicly traded and is then listed
                     on a national securities exchange, its closing price on the
                     date of determination on the principal national securities
                     exchange on which the Common Stock is listed or admitted to
                     trading as reported in The Wall Street Journal;

             (c)     if such Common Stock is publicly traded but is not quoted
                     on the Nasdaq National Market nor listed or admitted to
                     trading on a national securities exchange, the average of
                     the closing bid and asked prices on the date of
                     determination as reported in The Wall Street Journal; or

             (d)     if none of the foregoing is applicable, by the Board in
                     good faith, which in the case of the First Offering Date
                     will be the price per share at which shares of the
                     Company's Common Stock are initially offered for sale to
                     the public by the Company's underwriters in the initial
                     public offering of the Company's Common Stock pursuant to a
                     registration statement filed with the SEC under the
                     Securities Act.

        9. PAYMENT OF PURCHASE PRICE; CHANGES IN PAYROLL DEDUCTIONS; ISSUANCE OF
SHARES.

          (a) The purchase price of the shares is accumulated by regular payroll
deductions made during each Offering Period. The deductions are made as a
percentage of the participant's compensation in one percent (1%) increments not
less than two percent (2%), nor greater than ten percent (10%) or such lower
limit set by the Committee. Compensation shall mean all W-2 cash compensation,
including, but not limited to, base salary, wages, commissions, overtime, shift
premiums and bonuses, plus draws against commissions, provided, however, that
for purposes of determining a participant's compensation, any election by such
participant to reduce his or her regular cash remuneration under Sections 125 or
401(k) of the Code shall be treated as if the participant did not make such
election. Payroll deductions shall commence on the first payday of the Offering
Period and shall continue to the end of the Offering Period unless sooner
altered or terminated as provided in this Plan.

          (b) A participant may increase or decrease the rate of payroll
deductions during an Offering Period by filing with the Treasury Department a
new authorization for payroll deductions, in which case the new rate shall
become effective for the next payroll period commencing more than fifteen (15)
days after the Treasury Department's receipt of the authorization and shall
continue for the remainder of the Offering Period unless changed as described
below. Such change in the rate of payroll deductions may be made at any time
during an Offering Period, but not more than one (1) change may be made
effective during any Purchase Period. A participant may increase or decrease the
rate of payroll deductions for any subsequent Offering Period by filing with the
Treasury Department a new authorization for payroll deductions not later than
fifteen (15) days before the beginning of such Offering Period.

          (c) A participant may reduce his or her payroll deduction percentage
to zero during an Offering Period by filing with the Treasury Department a
request for cessation of payroll deductions. Such reduction shall be effective
beginning with the next payroll period commencing more than fifteen (15) days
after the Treasury Department's receipt of the request and no further payroll
deductions will be made for the duration of the Offering Period. Payroll
deductions credited to the participant's account prior to the effective date of
the request shall be used to purchase shares of Common Stock of the Company in
accordance with Section (e) below. A participant may not resume making payroll
deductions during the Offering Period in which he or she reduced his or her
payroll deductions to zero.

                                               1999 Employee Stock Purchase Plan


          (d) All payroll deductions made for a participant are credited to his
or her account under this Plan and are deposited with the general funds of the
Company. No interest accrues on the payroll deductions. All payroll deductions
received or held by the Company may be used by the Company for any corporate
purpose, and the Company shall not be obligated to segregate such payroll
deductions.

          (e) On each Purchase Date, so long as this Plan remains in effect and
provided that the participant has not submitted a signed and completed
withdrawal form before that date which notifies the Company that the participant
wishes to withdraw from that Offering Period under this Plan and have all
payroll deductions accumulated in the account maintained on behalf of the
participant as of that date returned to the participant, the Company shall apply
the funds then in the participant's account to the purchase of whole shares of
Common Stock reserved under the option granted to such participant with respect
to the Offering Period to the extent that such option is exercisable on the
Purchase Date. The purchase price per share shall be as specified in Section 8
of this Plan. Any cash remaining in a participant's account after such purchase
of shares shall be refunded to such participant in cash, without interest;
provided, however that any amount remaining in such participant's account on a
Purchase Date which is less than the amount necessary to purchase a full share
of Common Stock of the Company shall be carried forward, without interest, into
the next Purchase Period or Offering Period, as the case may be. In the event
that this Plan has been oversubscribed, all funds not used to purchase shares on
the Purchase Date shall be returned to the participant, without interest. No
Common Stock shall be purchased on a Purchase Date on behalf of any employee
whose participation in this Plan has terminated prior to such Purchase Date.

          (f) As promptly as practicable after the Purchase Date, the Company
shall issue shares for the participant's benefit representing the shares
purchased upon exercise of his or her option.

          (g) During a participant's lifetime, his or her option to purchase
shares hereunder is exercisable only by him or her. The participant will have no
interest or voting right in shares covered by his or her option until such
option has been exercised.

        10. LIMITATIONS ON SHARES TO BE PURCHASED.

           (a) No participant shall be entitled to purchase stock under this
Plan at a rate which, when aggregated with his or her rights to purchase stock
under all other employee stock purchase plans of the Company or any Subsidiary,
exceeds $25,000 in fair market value, determined as of the Offering Date (or
such other limit as may be imposed by the Code) for each calendar year in which
the employee participates in this Plan. The Company shall automatically suspend
the payroll deductions of any participant as necessary to enforce such limit
provided that when the Company automatically resumes such payroll deductions,
the Company must apply the rate in effect immediately prior to such suspension.

           (b) No more than two hundred percent (200%) of the number of shares
determined by using eighty-five percent (85%) of the fair market value of a
share of the Company's Common Stock on the Offering Date as the denominator may
be purchased by a participant on any single Purchase Date.

           (c) No participant shall be entitled to purchase more than the
Maximum Share Amount (as defined below) on any single Purchase Date. Not less
than thirty (30) days prior to the commencement of any Offering Period, the
Committee may, in its sole discretion, set a maximum number of shares which may
be purchased by any employee at any single Purchase Date (hereinafter the
"MAXIMUM SHARE AMOUNT"). Until otherwise determined by the Committee, there
shall be no Maximum Share Amount. In no event shall the Maximum Share Amount
exceed the amounts permitted under Section 10(b) above. If a new Maximum Share
Amount is set, then all participants must be notified of such Maximum Share
Amount prior to the commencement of the next Offering Period. The Maximum Share
Amount shall continue to apply with respect to all succeeding Purchase Dates and
Offering Periods unless revised by the Committee as set forth above.

           (d) If the number of shares to be purchased on a Purchase Date by all
employees participating in this Plan exceeds the number of shares then available
for issuance under this Plan, then the Company will make a pro rata allocation
of the remaining shares in as uniform a manner as shall be reasonably
practicable and as the Com-

                                               1999 Employee Stock Purchase Plan


mittee shall determine to be equitable. In such event, the Company shall give
written notice of such reduction of the number of shares to be purchased under a
participant's option to each participant affected.

           (e) Any payroll deductions accumulated in a participant's account
which are not used to purchase stock due to the limitations in this Section 10
shall be returned to the participant as soon as practicable after the end of the
applicable Purchase Period, without interest.

        11.  WITHDRAWAL.

           (a) Each participant may withdraw from an Offering Period under this
Plan by signing and delivering to the Treasury Department a written notice to
that effect on a form provided for such purpose. Such withdrawal may be elected
at any time at least fifteen (15) days prior to the end of an Offering Period.

           (b) Upon withdrawal from this Plan, the accumulated payroll
deductions shall be returned to the withdrawn participant, without interest, and
his or her interest in this Plan shall terminate. In the event a participant
voluntarily elects to withdraw from this Plan, he or she may not resume his or
her participation in this Plan during the same Offering Period, but he or she
may participate in any Offering Period under this Plan which commences on a date
subsequent to such withdrawal by filing a new authorization for payroll
deductions in the same manner as set forth in Section 6 above for initial
participation in this Plan.

           (c) If the Fair Market Value on the first day of the current Offering
Period in which a participant is enrolled is higher than the Fair Market Value
on the first day of any subsequent Offering Period, the Company will
automatically enroll such participant in the subsequent Offering Period. Any
funds accumulated in a participant's account prior to the first day of such
subsequent Offering Period will be applied to the purchase of shares on the
Purchase Date immediately prior to the first day of such subsequent Offering
Period, if any.

        12. TERMINATION OF EMPLOYMENT. Termination of a participant's employment
for any reason, including retirement, death or the failure of a participant to
remain an eligible employee of the Company or of a Participating Subsidiary,
immediately terminates his or her participation in this Plan. In such event, the
payroll deductions credited to the participant's account will be returned to him
or her or, in the case of his or her death, to his or her legal representative,
without interest. For purposes of this Section 12, an employee will not be
deemed to have terminated employment or failed to remain in the continuous
employ of the Company or of a Participating Subsidiary in the case of sick
leave, military leave, or any other leave of absence approved by the Board;
provided that such leave is for a period of not more than ninety (90) days or
reemployment upon the expiration of such leave is guaranteed by contract or
statute.

        13. RETURN OF PAYROLL DEDUCTIONS. In the event a participant's interest
in this Plan is terminated by withdrawal, termination of employment or
otherwise, or in the event this Plan is terminated by the Board, the Company
shall deliver to the participant all payroll deductions credited to such
participant's account. No interest shall accrue on the payroll deductions of a
participant in this Plan.

        14. CAPITAL CHANGES. Subject to any required action by the stockholders
of the Company, the number of shares of Common Stock covered by each option
under this Plan which has not yet been exercised and the number of shares of
Common Stock which have been authorized for issuance under this Plan but have
not yet been placed under option (collectively, the "RESERVES"), as well as the
price per share of Common Stock covered by each option under this Plan which has
not yet been exercised, shall be proportionately adjusted for any increase or
decrease in the number of issued and outstanding shares of Common Stock of the
Company resulting from a stock split or the payment of a stock dividend (but
only on the Common Stock) or any other increase or decrease in the number of
issued and outstanding shares of Common Stock effected without receipt of any
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration". Such adjustment shall be made by the
Committee, whose determination shall be final, binding and conclusive. Except as
expressly provided herein, no issue by the Company of shares of stock of any
class, or securities convertible into shares of stock of any class, shall
affect, and no adjustment by reason thereof shall be made with respect to, the
number or price of shares of Common Stock subject to an option.

                                               1999 Employee Stock Purchase Plan


      In the event of the proposed dissolution or liquidation of the Company,
the Offering Period will terminate immediately prior to the consummation of such
proposed action, unless otherwise provided by the Committee. The Committee may,
in the exercise of its sole discretion in such instances, declare that this Plan
shall terminate as of a date fixed by the Committee and give each participant
the right to purchase shares under this Plan prior to such termination. In the
event of (i) a merger or consolidation in which the Company is not the surviving
corporation (other than a merger or consolidation with a wholly-owned
subsidiary, a reincorporation of the Company in a different jurisdiction, or
other transaction in which there is no substantial change in the stockholders of
the Company or their relative stock holdings and the options under this Plan are
assumed, converted or replaced by the successor corporation, which assumption
will be binding on all participants), (ii) a merger in which the Company is the
surviving corporation but after which the stockholders of the Company
immediately prior to such merger (other than any stockholder that merges, or
which owns or controls another corporation that merges, with the Company in such
merger) cease to own their shares or other equity interest in the Company, (iii)
the sale of all or substantially all of the assets of the Company or (iv) the
acquisition, sale, or transfer of more than 50% of the outstanding shares of the
Company by tender offer or similar transaction, the Plan will continue with
regard to Offering Periods that commenced prior to the closing of the proposed
transaction and shares will be purchased based on the Fair Market Value of the
surviving corporation's stock on each Purchase Date, unless otherwise provided
by the Committee consistent with pooling of interests accounting treatment.

      The Committee may, if it so determines in the exercise of its sole
discretion, also make provision for adjusting the Reserves, as well as the price
per share of Common Stock covered by each outstanding option, in the event that
the Company effects one or more reorganizations, recapitalizations, rights
offerings or other increases or reductions of shares of its outstanding Common
Stock, or in the event of the Company being consolidated with or merged into any
other corporation.

        15. NONASSIGNABILITY. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under this Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 22 below) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be void and
without effect.

        16. REPORTS. Individual accounts will be maintained for each participant
in this Plan. Each participant shall receive promptly after the end of each
Purchase Period a report of his or her account setting forth the total payroll
deductions accumulated, the number of shares purchased, the per share price
thereof and the remaining cash balance, if any, carried forward to the next
Purchase Period or Offering Period, as the case may be.

        17. NOTICE OF DISPOSITION. Each participant shall notify the Company in
writing if the participant disposes of any of the shares purchased in any
Offering Period pursuant to this Plan if such disposition occurs within two (2)
years from the Offering Date or within one (1) year from the Purchase Date on
which such shares were purchased (the "NOTICE PERIOD"). The Company may, at any
time during the Notice Period, place a legend or legends on any certificate
representing shares acquired pursuant to this Plan requesting the Company's
transfer agent to notify the Company of any transfer of the shares. The
obligation of the participant to provide such notice shall continue
notwithstanding the placement of any such legend on the certificates.

        18. NO RIGHTS TO CONTINUED EMPLOYMENT. Neither this Plan nor the grant
of any option hereunder shall confer any right on any employee to remain in the
employ of the Company or any Participating Subsidiary, or restrict the right of
the Company or any Participating Subsidiary to terminate such employee's
employment.

        19. EQUAL RIGHTS AND PRIVILEGES. All eligible employees shall have equal
rights and privileges with respect to this Plan so that this Plan qualifies as
an "employee stock purchase plan" within the meaning of Section 423 or any
successor provision of the Code and the related regulations. Any provision of
this Plan which is inconsistent with Section 423 or any successor provision of
the Code shall, without further act or amendment by the Company, the Committee
or the Board, be reformed to comply with the requirements of Section 423. This
Section 19 shall take precedence over all other provisions in this Plan.

        20. NOTICES. All notices or other communications by a participant to the
Company under or in connection with this Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

        21. TERM; STOCKHOLDER APPROVAL. After this Plan is adopted by the Board,
this Plan will become effective on the First Offering Date (as defined above).
This Plan shall be approved by the stockholders of the Company, in any manner
permitted by applicable corporate law, within twelve (12) months before or after
the date this Plan is adopted by the Board. No purchase of shares pursuant to
this Plan shall occur prior to such stockholder approval. This Plan shall
continue until the earlier to occur of (a) termination of this Plan by the Board
(which termination may be effected by the Board at any time), (b) issuance of
all of the shares of Common Stock reserved for issuance under this Plan, or (c)
ten (10) years from the adoption of this Plan by the Board.

        22.  DESIGNATION OF BENEFICIARY.

             (a) A participant may file a written designation of a beneficiary
who is to receive any shares and cash, if any, from the participant's account
under this Plan in the event of such participant's death subsequent to the end
of an Purchase Period but prior to delivery to him of such shares and cash. In
addition, a participant may file a written designation of a beneficiary who is
to receive any cash from the participant's account under this Plan in the event
of such participant's death prior to a Purchase Date.

             (b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under this
Plan who is living at the time of such participant's death, the Company shall
deliver such shares or cash to the executor or administrator of the estate of
the participant, or if no such executor or administrator has been appointed (to
the knowledge of the Company), the Company, in its discretion, may deliver such
shares or cash to the spouse or to any one or more dependents or relatives of
the participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.

        23. CONDITIONS UPON ISSUANCE OF SHARES; LIMITATION ON SALE OF SHARES.
Shares shall not be issued with respect to an option unless the exercise of such
option and the issuance and delivery of such shares pursuant thereto shall
comply with all applicable provisions of law, domestic or foreign, including,
without limitation, the Securities Act, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange or automated quotation system upon which the shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance.

        24. APPLICABLE LAW. The Plan shall be governed by the substantive laws
(excluding the conflict of laws rules) of the State of California.

        25. AMENDMENT OR TERMINATION OF THIS PLAN. The Board may at any time
amend, terminate or extend the term of this Plan, except that any such
termination cannot affect options previously granted under this Plan, nor may
any amendment make any change in an option previously granted which would
adversely affect the right of any participant, nor may any amendment be made
without approval of the stockholders of the Company obtained in accordance with
Section 21 above within twelve (12) months of the adoption of such amendment (or
earlier if required by Section 21) if such amendment would:

        (a) increase the number of shares that may be issued under this Plan; or

        (b) change the designation of the employees (or class of employees)
eligible for participation in this Plan.

        Notwithstanding the foregoing, the Board may make such amendments to the
Plan as the Board determines to be advisable, if the continuation of the Plan or
any Offering Period would result in financial accounting treatment

AGREEMENT BETWEEN INDUS AND BROADBASE


Understanding that Indus and Broadbase are, and will continue to, make good
faith efforts toward the successful conclusion of an OEM relationship, both
parties agree to the following:

Broadbase agrees to take an active role in the development, testing and release
of the Indus Knowledge Warehouse (IKW).

In consideration for Broadbase's efforts Indus agrees to commit to a prepayment
of OEM royalties in the amount of $[*] on or before March 31, 1999.

This prepay balance can be used to offset royalty payments due from Indus to
Broadbase on sales of the IKW on or after the general availability release of
the product at a rate of [*]% of the amounts owed.

The amounts of the royalty payments owed will be calculated in accordance with
whatever OEM agreement is in effect at the time the amount owed is incurred.

The prepay balance may not be used to offset amounts owed for consulting,
training, maintenance, or technical support.

The $[*] prepayment of royalties will be due upon the General Availability
release of the IKW product (expected on July 1).

breach within thirty (30) days following written notice.

1.3.    Rights and Duties Upon Termination. Termination of a BPA will not limit

information and authority necessary to perform the above.

have been avoided by the use of a current release of the Software; (ii) the
combination, operation, or use of any Software furnished under any BPA with
programs or data not provided by Broadbase, if such infringement would have been
avoided by the use of the Software without such programs or data; or (iii)
modifications to the Software by any party other thanthan Broadbase, if such
infringement would have been avoided in the absence of such modifications.

        (c) In the event that the Software is held, or is believed by Broadbase,

expense, to: (i) modify the Software to be noninfringing, (ii) obtain for
Partner a license to continue its use of the Software; or (iii) terminate the

Terms and Conditions. It is expressly agreed that any terms and conditions of
Partner's purchase orders and/or other forms will be superseded by the relevant

computer system on which the Program is in use differs from the single computer
system for which license rights have been granted to the licensee, the licensee
shall be invoiced for the additional copies, users or computer systems at the
prices quoted in the then current price list of Broadbase (subject to any
applicable discounts to which ASP Partner may have agreed). The additional
license fees shall be payable within thirty (30) days of such invoice;

(9)     The licensee shall not release the results of any benchmark of the
Program to any third party without the prior written approval of ASP Partner's
licensor for each such release;

(10)    Licensee acknowledges its responsibility to (i) regularly back-up data
maintained on any computer system using the Program, and (ii) adequately test
prior to deployment each production version of the Program in a configuration
which reasonably simulates licensee's planned production environment.

        ANY BPA IN ACCORDANCE WITH ITS TERMS. BOTH PARTIES WAIVE ANY RIGHT THEY
        MAY HAVE TO RECEIVE ANY COMPENSATION OR REPARATIONS ON TERMINATION OF
        ANY BPA UNDER THE LAW OF THE TERRITORY DESIGNATED IN THE BPA OR
        OTHERWISE, OTHER THAN EXPRESSLY PROVIDED THEREIN. Neither party will be
        liable to the other party on account of termination of any BPA for
        reimbursement or damages for the loss of goodwill, prospective profits
        or anticipated income, or on account of any expenditures, investments,
        leases or commitments made by either party or for any other reason
        whatsoever based upon or growing out of such termination or expiration.
        Partner acknowledges that (i) Partner has no expectation and has
        received no assurances that any investment by Partner in the promotion

        vested, proprietary or other right in the promotion of Broadbase
        products or in "goodwill" created by its efforts thereunder. THE PARTIES
        ACKNOWLEDGE THAT THIS SECTION 1.4 HAS BEEN INCLUDED AS A MATERIAL
        INDUCEMENT FOR BROADBASE TO ENTER INTO ANY BPA AND THAT BROADBASE WOULD
        NOT HAVE ENTERED INTO ANY BPA BUT FOR THE LIMITATIONS OF LIABILITY SET
        FORTH HEREIN.

        party ("Confidential Information"), and will use best efforts to
        maintain the confidentiality of all Confidential Information in its
        possession or control, which will in no event be less than the measures

        importance. Confidential Information will not include information that:

        Conditions, any BPA or any other confidentiality agreement between the
        parties; (b) either party received from a third party without

                                   EXHIBIT F

This Exhibit F ("Exhibit F") dated June 30, 1999, entered into by Indus
International, Inc. ("Partner") and BROADBASE INFORMATION SYSTEMS (Broadbase)
supplements the terms of the Broadbase Partner Agreement dated June 2, 1998
between Partner and Broadbase (the "Agreement"). Capitalized terms not otherwise
defined in this Exhibit shall have the same meaning as in the Agreement.

TERM: Term of the Agreement shall be extended to 2 years from the date of this
Exhibit and will automatically renew for an additional [one (1) year] term per
the terms defined in section 11 in the Agreement. License and distribution
rights for the Brio products are excluded from this agreement unless mutually
agreed upon on a case-by-case basis.

TERMINATION: Upon termination or expiration of this Agreement, license and
distribution rights of the Broadbase products (excluding Brio) will survive
until all prepaid royalties are used up.

PREPAYMENT ROYALTY: Partner agrees to make a nonrefundable prepayment of future
royalties in the amount of $[*] on net 30 day terms from the execution
date of this Exhibit. (This prepayment brings the total prepay balance to
$[*]).

ROYALTY: Partner agrees to pay a royalty to Broadbase equaling a percentage of
the actual selling price of the Derivative Offering. (For the purposes of this
agreement "Derivative Offering" means both the Partner software which contains
Broadbase Products and any annual software maintenance and/or support fees.)

Cumulative revenue shall include all revenue from the sale of the Derivative
Offering from the execution of this Exhibit forward. Royalty amounts will be
calculated on the following graduated scale.

                                      [*]

ROYALTY REPORTING: Partner agrees to report royalty and/or royalty burn down on
an Exhibit D within 10 business days after the end of the same calendar quarter
that the royalty or royalty burn-down has occurred.

BURN-DOWN RATE: Prepaid royalties are decremented at 100% of royalty amounts
due.

MINIMUM ROYALTY: Notwithstanding the above, in no event shall the pricing per
End User be less than $[*].

MAXIMUM ROYALTY: Notwithstanding the above, in no event shall royalty be paid on
amounts in excess of $[*] of the actual selling price for each End User
transaction. The parties may mutually agree to exceptions to the Maximum and
Minimum Royalty.

USE LIMITATIONS: End User license rights exclude the use of the Broadbase
software independently of the Derivative Offering. License rights do include the
ability to access, extract, transform, or contain data from data sources other
than those owned or controlled by the Partner but only insofar as data from
these sources is added to the Derivative Offering. If an End User customer
wishes to use the Broadbase software as a general purpose tool (and to build
applications that are independent of the Derivative Offering), they will be
required to contract directly with Broadbase.
