                               PROSPECTUS SUMMARY

     This summary highlights information contained elsewhere in this prospectus.
You should read the entire prospectus carefully, including the risk factors
beginning on page 6.

                                E.PIPHANY, INC.


     We develop and market software that enables companies to establish,
maintain and continually improve customer relationships across both Internet and
traditional sales, marketing and distribution channels. Our E.piphany E.4 System
is an integrated family of software solutions that companies can deploy to
collect and analyze data from their existing software systems, and from third
party data providers, to profile their customers' characteristics and
preferences. Business users can then act on this information by using our
software to design and execute marketing campaigns as well as customize
products, services and related customer interactions. By using our software to
address the unique characteristics and preferences of each customer, we believe
companies are able to improve the longevity and profitability of their customer
relationships. We believe that E.piphany E.4 System is differentiated from other
software by its combination of the following characteristics:



     - Our software is designed to enable business users to establish, maintain
       and improve customer relationships. Our software solutions are designed
       to enable a continuous process that helps businesses identify and
       differentiate their customers and then customize products, services and
       related interactions based on customer characteristics and preferences.



     - Our software utilizes a Web-based design to promote ease of use and
       wide-scale deployment to business users. Our software is easy-to-use and
       is accessed by business users across a corporate network or the Internet
       using only a standard Web browser. This Web-based design does not require
       our software to be installed on each user's computer, but only in a
       single location, which reduces the costs of deploying and maintaining the
       software.



     - Our software is packaged for faster and less expensive
       implementation. Our software is a single integrated family of software
       solutions that includes technologies to extract, manage, analyze and act
       on customer data. This eliminates the need for a company to integrate
       multiple software tools from various vendors or develop custom software
       to solve specific business problems. Our software solutions can generally
       be implemented in 16 weeks or less.



     We generate revenue by licensing our software to large and medium sized
businesses and by providing related consulting, implementation and maintenance
services. We market our products through our direct sales force, and indirectly
through agreements with third parties to resell our software. As of June 30,
1999, we have licensed our products to Acxiom, Agilent Technologies, Autodesk,
California State Automobile Association, Capital Blue Cross, Charles Schwab,
DIRECTV, Envision, Fair, Isaac, FileNET, Hewlett-Packard, Hilton Hotels, KPMG,
Lucent Technologies, Macromedia, Microsoft, Nissan North America, Sallie Mae,
Visio and Wells Fargo, among others.



     Our revenue increased from $3.4 million in 1998 to $5.1 million in the
first six months of 1999. We have a limited operating history and have incurred
significant losses, including a loss of $9.3 million for the six months ended
June 30, 1999, and have an accumulated deficit of $22.8 million as of June 30,
1999. We expect to incur net losses in the foreseeable future, and these losses
may be substantial. The market in which we compete is highly competitive.



     We were incorporated in Delaware in November 1996 as Epiphany Marketing
Automation, Inc. In March 1997, we changed our name to Epiphany Marketing
Software, Inc., and in April 1999, we changed our name to E.piphany, Inc. Our
principal executive offices are located at 2300 Geng Road, Suite 200, Palo Alto,
California 94303, and our telephone number is (650) 496-2430. Our World Wide Web
site is located at http://www.epiphany.com. Information contained on our World
Wide Web site does not constitute part of this prospectus.

                                  RISK FACTORS

     An investment in our common stock is very risky. You should carefully
consider the risks described below, together with all of the other information
included in this prospectus, before buying shares in this offering.

WE HAVE A HISTORY OF LOSSES, WE EXPECT LOSSES IN THE FUTURE AND WE MAY NOT EVER
BECOME PROFITABLE


     We incurred net losses of $9.3 million in the six months ended June 30,
1999, $10.3 million in 1998 and $3.1 million in 1997. We had an accumulated
deficit of $22.8 million as of June 30, 1999. We expect to incur net losses in
the foreseeable future. These losses may be substantial, and we may not ever
become profitable. In addition, we expect to significantly increase our expenses
in the near term, especially research and development and sales and marketing
expenses. Therefore, our operating results will be harmed if our revenue does
not keep pace with our expected increase in expenses or is not sufficient for us
to achieve profitability. If we do achieve profitability in any period, we
cannot be certain that we will sustain or increase profitability on a quarterly
or annual basis.



OUR LIMITED OPERATING HISTORY MAKES FINANCIAL FORECASTING AND EVALUATION OF OUR
BUSINESS DIFFICULT



     We were founded in November 1996, and our limited operating history makes
it difficult to forecast our future operating results. Our revenue and income
potential is unproven. We received our first revenues from licensing our
software and performing related services in early 1998, and we began shipping
our most recent product in June 1999. Since we do not have a long history upon
which to base forecasts of future operating results, any predictions about our
future revenues and expenses may not be as accurate as they would be if we had a
longer business history.


VARIATIONS IN QUARTERLY OPERATING RESULTS DUE TO SUCH FACTORS AS CHANGES IN
DEMAND FOR OUR PRODUCTS AND CHANGES IN OUR MIX OF REVENUES MAY CAUSE OUR STOCK
PRICE TO DECLINE


     We expect our quarterly operating results to fluctuate. We therefore
believe that quarter-to-quarter comparisons of our operating results may not be
a good indication of our future performance, and you should not rely on them to
predict our future performance or the future performance of our stock price. Our
short-term expense levels are relatively fixed and are based on our expectations
of future revenues. As a result, a reduction in revenues in a quarter may harm
our operating results for that quarter. Although our operating results have
generally improved from quarter-to-quarter in the past, our quarterly revenues,
expenses and operating results could vary significantly from quarter-to-quarter
for several reasons. If our operating results in future quarters fall below the
expectations of market analysts and investors, the trading price of our common
stock will fall. Factors that may cause our operating results to fluctuate on a
quarterly basis are:


     - Varying size, timing and contractual terms of orders for our products

     - Our ability to timely complete our service obligations related to product
       sales

     - Changes in the mix of revenue attributable to higher-margin product
       license revenue as opposed to substantially lower-margin service revenue

     - Customers' decisions to defer orders or implementations, particularly
       large orders or implementations, from one quarter to the next, including
       decisions to defer related to year 2000 concerns


     - Changes in demand for our E.piphany E.4 System software or for enterprise
       software solutions generally



     - Increased competition and announcements or introduction of new products
       by our competitors.



     - Changes in our pricing policies, due to competitive pressures or
       increased costs


     - Varying budgeting cycles of our customers and potential customers

                                        6
<PAGE>   9


     - Potential downturns in our customers' or potential customers' businesses,
       particularly in the high technology, financial services and health care
       services industries



     - Our ability to develop and introduce new or enhanced versions of our
       products on schedule and quickly enough to anticipate or respond to
       competitors' offerings


     - Software defects and other product quality problems, and


     - Any increase in our need to supplement our professional services
       organization by subcontracting to more expensive third-party consultants
       to help provide implementation, support and training services when our
       own capacity is constrained.



IF WE FAIL TO EXPAND OUR PROFESSIONAL SERVICES ORGANIZATION, OUR REVENUES AND
PROFITABILITY WOULD BE HARMED



     Customers that license our software typically require significant
assistance with consulting, implementation, maintenance and training. When we
sell our software, we frequently enter into contracts for these services and
recognize revenue from the licensing of our software products as the
implementation services are performed. Our professional services organization
provides most of these services. If our professional services organization does
not effectively implement and support our products or if we are unable to expand
our professional services organization, our ability to sell software and
accordingly our revenues will be harmed. In addition, due to the method we use
to recognize revenue, delays in providing implementation services will delay our
recognition of revenue. If we are unable to expand our professional services
organization to keep pace with sales, we will be required to increase our use of
subcontractors to help meet our implementation and service obligations, which
will result in lower gross margins.



IF CUSTOMERS DO NOT CONTRACT DIRECTLY WITH THIRD PARTIES TO IMPLEMENT AND
SUPPORT OUR PRODUCTS, OUR REVENUES AND PROFITABILITY WILL BE HARMED



     In addition to providing services through our professional services
organization, we encourage our customers to purchase consulting, implementation,
maintenance and training services directly from third-party consulting
organizations. If these third-party consulting organizations are unwilling or
unable to provide these services or if customers are unwilling to use these
third-party consulting organizations, our revenues and profitability will be
harmed. We believe that using third-party integrators to provide support to our
customers is necessary for us to increase software sales and improve our
margins. As a result, if we are not able to effectively enter into, develop and
manage relationships with these third party consulting organizations, our
revenues and margins will be harmed. We need to identify third parties who can
effectively promote our products, negotiate favorable agreements with these
third parties and provide proper incentives for these third parties to promote
our products, including delivering quality products and providing adequate
support for our products.



OUR SERVICES REVENUES HAVE A SUBSTANTIALLY LOWER MARGIN THAN OUR PRODUCT
REVENUES, AND AN INCREASE IN SERVICE REVENUES RELATIVE TO LICENSE REVENUES COULD
HARM OUR PROFITABILITY



     Services revenues, which includes fees for implementation, consulting,
support and training, were 43% of our revenues for the six months ended June 30,
1999 and 34% of our revenues for the year ended December 31, 1998. Our services
revenues have a substantially lower gross margin than license revenues. Our cost
of services revenues for the six months ended June 30, 1999 was 113% of our
services revenues. An increase in the percentage of total revenues represented
by services revenues could adversely affect our overall gross margins and
operating results.


     Services revenues as a percentage of total revenues and cost of services
revenues as a percentage of total revenues have varied significantly from
quarter to quarter due to our relatively early stage of development. The
relative amount of services revenues as compared to license revenues has varied
based

                                        7
<PAGE>   10


on the volume of solution orders compared to the volume of additional user
orders. In addition, the amount and profitability of services can depend in
large part on:



     - the solution which has been licensed



     - the complexity of the customers' information technology environment



     - the resources directed by customers to their implementation projects



     - the number of users licensed, and



     - the extent to which our strategic third party integrators provide
       services directly to customers.



NEW PRODUCT INTRODUCTIONS AND PRICING STRATEGIES BY OUR COMPETITORS COULD
ADVERSELY AFFECT OUR ABILITY TO SELL OUR PRODUCTS AND COULD RESULT IN PRESSURE
TO PRICE OUR PRODUCTS IN A MANNER THAT REDUCES OUR MARGINS


     Competitive pressures could prevent us from growing, reduce our market
share or require us to reduce prices on our products and services, any of which
could harm our business.

     We compete principally with vendors of:


     - decision support and data warehousing software, such as Brio Technology,
       Business Objects, Cognos, Informatica and Sagent Technology



     - enterprise application software, such as i2 Technologies, Oracle,
       Peoplesoft, SAP and Siebel Systems, and



     - campaign management software, such as Exchange Applications and Prime
       Response.



     Many of these companies have significantly greater financial, technical,
marketing, service and other resources. Many of these companies also have a
larger installed base of users, have been in business longer or have greater
name recognition than we do. For example, in fiscal 1998 the annual revenue of
Oracle exceeded $7.1 billion, and the annual revenue of Siebel Systems exceeded
$350 million. Some large companies may attempt to build capabilities into their
products that are similar to the capabilities of our products. Some of our
competitors' products may be more effective than our products at performing
particular functions or be more customized for particular needs. Even if these
functions are more limited than those provided by our products, our competitors'
products could discourage potential customers from purchasing our products,
particularly if their products incorporate other capabilities, such as
transactional database systems. Further, our competitors may be able to respond
more quickly than we can to changes in customer requirements.



     In addition, our products must integrate with software solutions provided
by a number of our existing or potential competitors. These competitors could
alter their products so that our products no longer integrate well with them, or
they could deny or delay access by us to advance software releases that allow us
to timely adapt our products to integrate with their products.



     Our competitors have made and may also continue to make strategic
acquisitions or establish cooperative relationships among themselves or with
other software vendors, which may increase the ability of their products to
address the needs of our prospective customers, particularly the need for a
single comprehensive data integration and analytic application solution. Our
competitors may also establish or strengthen cooperative relationships with our
current or future distributors or strategic partners, thereby limiting our
ability to sell through these channels.


                                        8
<PAGE>   11


OUR REVENUES MIGHT BE HARMED BY RESISTANCE TO ADOPTION OF OUR SOFTWARE BY
INFORMATION TECHNOLOGY DEPARTMENTS



     Some businesses may have already made a substantial investment in other
third party or internally developed solutions designed to integrate data from
disparate sources and analyze this data or manage marketing campaigns. These
companies may be reluctant to abandon these investments in favor of our
software. In addition, information technology departments of potential customers
may resist purchasing our software solutions for a variety of other reasons,
particularly the potential displacement of their historical role in creating and
running software and concerns that packaged software products are not
sufficiently customizable for their enterprises. If the market for our products
does not grow for any of these reasons, our revenues may be harmed.



IF THE MARKET IN WHICH WE SELL OUR PRODUCTS AND SERVICES DOES NOT GROW AS WE
ANTICIPATE, OUR REVENUES WILL BE REDUCED



     If the market for software that enables companies to establish, maintain
and continually improve customer relationships does not grow as quickly or
become as large as we anticipate, our revenues will be reduced. Our market is
still emerging, and our success depends on its growth. Our potential customers
may:


     - not understand or see the benefits of using these products

     - not achieve favorable results using these products

     - experience technical difficulty in implementing or using these products,
       or


     - use alternative methods to solve the same business problems.



     In addition, because our products can be used in connection with Internet
commerce and we are currently developing additional Internet commerce solutions,
if the Internet commerce market does not grow as quickly as we anticipate, we
may experience sales which are lower than our expectations.



IF WE FAIL TO DEVELOP NEW PRODUCTS OR IMPROVE OUR EXISTING PRODUCTS TO MEET OR
ADAPT TO THE CHANGING NEEDS AND STANDARDS OF OUR INDUSTRY, SALES OF OUR PRODUCTS
MAY DECLINE



     Our future success depends on our ability to address the rapidly changing
needs of our customers. We must maintain and improve our E.piphany E.4 System
and develop new products that include new technological developments, keep pace
with products of our competitors and satisfy the changing requirements of our
customers. If we do not, we may not achieve market acceptance, we may lose
existing customers and we may be unable to attract new customers. To achieve
increased market acceptance of our products, we must, among other things,
continue to:



     - improve and introduce new software for reporting and analysis,
       distributed database marketing and e-commerce



     - improve the effectiveness of our software, particularly in
       implementations involving very large databases and large numbers of
       simultaneous users


     - enhance our software's ease of administration


     - improve our software's ability to extract data from existing software
       systems, and


     - adapt to rapidly changing computer operating system and database
       standards and Internet technology.


     We may not be successful in developing and marketing these or other new or
improved products. If we are not successful, we may lose sales to competitors.


                                        9
<PAGE>   12


     In addition, we have entered into customer contracts which contain specific
performance goals relating to new product releases or enhancements, and if we
are not able to meet these goals, we may be required to, among other things,
return fees, pay damages and offer discounts.



IF OUR PRODUCTS DO NOT STAY COMPATIBLE WITH POPULAR SOFTWARE PROGRAMS, WE MAY
LOSE SALES AND REVENUES



     Our E.piphany E.4 System must work with popular commercially available
software programs. If these software programs do not remain popular, or we do
not update our software to be compatible with newer versions of these programs,
we may lose customers.



     The E.piphany E.4 System software is designed to operate on computer
systems running the Microsoft Windows NT computer operating system and to be
accessible through standard Internet browsers such as Microsoft Internet
Explorer. Further, it is designed to be used with database software from
Microsoft and Oracle. If we fail to obtain access to developer versions of these
software products, we may be unable to build and enhance our products on
schedule.



     Our E.piphany E.4 System is also designed to access data stored in many
leading enterprise software systems, such as those from Oracle, PeopleSoft,
Siebel Systems and SAP, running on a variety of computer operating systems. If
we fail to enhance our software to be compatible with new versions of these
products, we may lose potential customers. If we lose customers, our revenues
and profitability may be harmed.



IF DATABASE ACCESS BECOMES STANDARDIZED, DEMAND FOR OUR PRODUCTS WILL BE REDUCED



     Our products are useful for integrating data from a variety of disparate
data sources. Adoption of uniform, industry-wide standards across various
database and analytic software programs could minimize the importance of the
data integration capabilities of our products. This, in turn, could adversely
affect the competitiveness and market acceptance of our products. Also, a single
competitor in the market for database and analytic software programs may become
dominant, even if there is no formal industry-wide standard. If large numbers of
our customers adopt a single standard, this would similarly reduce demand for
our product. If we lose customers because of the adoption of standards, we may
have lower revenues and profitability.


OUR PRODUCTS HAVE A LONG SALES CYCLE WHICH MAKES IT DIFFICULT TO PLAN OUR
EXPENSES AND FORECAST OUR RESULTS


     It takes us between three and six months to complete the majority of our
sales, but it can take us up to one year or longer. It is therefore difficult to
predict the quarter in which a particular sale will occur and to plan our
expenditures accordingly. The period between our initial contact with a
potential customer and their purchase of our products and services is relatively
long due to several factors, including:


     - the complex nature of our products

     - our need to educate potential customers about the uses and benefits of
       our products

     - the purchase of our products requires a significant investment of
       resources by a customer


     - our customers have budget cycles which affect the timing of purchases


     - many of our customers require competitive evaluation and internal
       approval before purchasing our products

     - potential customers may delay purchases due to announcements or planned
       introductions of new products by us or our competitors, and

     - many of our customers are large organizations which may require a long
       time to make decisions.


     The delay or failure to complete sales in a particular quarter could reduce
our revenues in that quarter, as well as subsequent quarters over which revenues
for the sale would likely be recognized. If our


                                       10
<PAGE>   13


sales cycle unexpectedly lengthens in general or for one or more large orders,
it would adversely affect the timing of our revenues. If we were to experience a
delay of several weeks on a large order, it could harm our ability to meet our
forecasts for a given quarter.



IF WE FAIL TO ESTABLISH, MAINTAIN OR EXPAND OUR RELATIONSHIPS WITH THIRD
PARTIES, OUR ABILITY TO GROW REVENUES COULD BE HARMED



     In order to grow our business, we must generate, retain and strengthen
relationships with third parties. To date, we have established relationships
with several companies, including system integrators and consultants that
implement our software such as Cambridge Technology Partners, Ernst & Young and
KPMG; resellers such as Acxiom and Harte Hanks; and Exactis.com, an application
service provider that provides access to our software to its customers over the
Internet. If the partners with which we have relationships do not provide
sufficient, high-quality service or integrate and support our software
correctly, our revenues may be harmed. In addition, the third parties with whom
we have relationships may offer products of other companies, including products
that compete with our products. We typically enter into contracts with third
parties that generally set out the nature of our relationships. However, our
contracts do not require these third parties to devote resources to promoting,
selling and supporting our products and therefore we have little control over
these third parties. We cannot assure you that we can generate and maintain
relationships that offset the significant time and effort that are necessary to
develop these relationships.



     We must also effectively take advantage of the resources and expertise of
third parties to help us develop additional E.piphany E.4 System software. Our
agreements with third parties do not require them to help us develop new
software. If we fail to effectively work with third parties, our ability to
increase revenues by broadening our solution offerings, particularly in
additional specific industries, will be limited.



IF WE FAIL TO EXPAND OUR DIRECT AND INDIRECT SALES CHANNELS, WE WILL NOT BE ABLE
TO INCREASE REVENUES



     In order to grow our business, we need to increase market awareness and
sales of our products and services. To achieve this goal, we need to increase
both our direct and indirect sales channels. If we fail to do so, this failure
could harm our ability to increase revenues. We currently receive substantially
all of our revenues from direct sales, but intend to increase sales through
indirect sales channels in the future. We need to expand our direct sales force
by hiring additional salespersons and sales management.



     We intend to derive our revenues from our indirect sales channel by selling
our software through value added resellers and application service providers. We
need to expand our indirect sales channel by entering into additional
relationships with these third parties.



     We have not derived a material amount of revenues from international sales
to date, but we expect as part of our strategy to increase international sales
principally through the use of indirect sales channels. We also plan to use
international direct sales personnel and therefore must hire additional sales
personnel outside the United States. We will be even more dependent on indirect
channels in the future due to our international strategy. Our ability to develop
and maintain these channels will significantly affect our ability to penetrate
international markets.


OUR REVENUES DEPEND ON A SMALL NUMBER OF LARGE ORDERS FROM OUR TOP CUSTOMERS AND
IF WE FAIL TO COMPLETE ONE OR MORE LARGE ORDERS, OUR REVENUES WILL BE REDUCED

     To date, we have received a significant portion of our revenues from a
small number of large orders. In the first half of 1999, orders from our top
four customers accounted for approximately 55% of our revenues. In 1998, orders
from our top five customers accounted for approximately 85% of our revenues. Our
operating results may be harmed if we are not able to complete one or more
substantial product sales in any future period or attract new customers.

                                       11
<PAGE>   14

IF CUSTOMERS DELAY INSTALLATIONS OR PURCHASES OF OUR PRODUCTS TO AVOID HAVING TO
PERFORM ADDITIONAL TESTS ON THEIR EXISTING SYSTEMS RELATED TO YEAR 2000
COMPLIANCE, OUR REVENUES WILL BE REDUCED IN THE NEAR TERM


     Many currently installed computer systems and software were written to
accept and process only two digits to represent the year when storing dates.
Beginning with the year 2000, these systems will need to accept four digit
entries to distinguish 21st century dates from 20th century dates. As a result,
computer systems and/or software products used by many companies may need to be
upgraded to solve this problem to avoid incorrect or lost data. In 1999, a
significant number of companies, including some of our current customers, may be
required to devote a substantial amount of their information technology
resources to testing systems for year 2000 compliance and fixing existing year
2000 problems. Some companies may delay installation of new systems during the
remainder of 1999 and possibly into early 2000 to avoid having to perform
additional tests on their existing systems. If these customers also defer
purchases of our products until their year 2000 problems have been resolved, it
will depress our sales in the near term.


WE HAVE GROWN VERY QUICKLY AND IF WE FAIL TO MANAGE OUR GROWTH, OUR ABILITY TO
GENERATE NEW REVENUES AND ACHIEVE PROFITABILITY WOULD BE HARMED

     We have grown significantly since our inception and need to grow quickly in
the future. Any failure to manage this growth could impede our ability to
increase revenues and achieve profitability. We have increased our number of
employees from 21 at December 31, 1997 to 115 at June 30, 1999. Future expansion
could be expensive and strain our management and other resources. In order to
manage growth effectively, we must:

     - hire, train and integrate new personnel

     - augment our financial and accounting systems

     - manage our sales operations, which are in several locations, and

     - expand our facilities.

THE LOSS OF KEY PERSONNEL OR ANY INABILITY TO ATTRACT AND RETAIN ADDITIONAL
PERSONNEL COULD AFFECT OUR ABILITY TO SUCCESSFULLY GROW OUR BUSINESS


     Our future success will depend in large part on our ability to hire and
retain a sufficient number of qualified personnel, particularly in sales,
marketing, research and development, service and support. If we are unable to do
so, this inability could affect our ability to grow our business. Competition
for qualified personnel in high technology is intense, particularly in the
Silicon Valley region of Northern California where our principal offices are
located. Our future success also depends upon the continued service of our
executive officers, and other key personnel, in particular our President and
Chief Executive Officer, Roger Siboni. The loss of the services of our executive
officers and other key personnel would harm our operations. None of our officers
or key personnel is bound by an employment agreement, and we do not maintain key
person insurance on any of our employees. We would also be harmed if one or more
of our officers or key employees decided to join a competitor or otherwise
compete with us.


IF OTHERS CLAIM THAT WE ARE INFRINGING THEIR INTELLECTUAL PROPERTY, WE COULD
INCUR SIGNIFICANT EXPENSES OR BE PREVENTED FROM SELLING OUR PRODUCTS


     We cannot assure you that others will not claim that we are infringing
their intellectual property rights or that we do not in fact infringe those
intellectual property rights. We have not conducted a search for existing
intellectual property registrations and we may be unaware of intellectual
property rights of others that may cover some of our technology.



     We have recently been contacted by a company who has asked us to evaluate
the need for a license of a patent it holds directed to data extraction
technology. This company has filed litigation alleging infringement of its
patent against three of our competitors. We cannot assure you that the holder of
the patent will not file litigation against us or that we would prevail in the
case of such litigation. In, addition,


                                       12
<PAGE>   15


the patent holder has informed us that it has applications pending in numerous
foreign countries. The patent holder may also have applications on file in the
United States covering related subject matter, which are confidential until the
patent is issued.



     Any litigation regarding this patent or other intellectual property could
be costly and time-consuming and divert the attention of our management and key
personnel from our business operations. The complexity of the technology
involved and the uncertainty of intellectual property litigation increase these
risks. Claims of intellectual property infringement might also require us to
enter into costly royalty or license agreements. However, we may not be able to
obtain royalty or licenses agreements on terms acceptable to us, or at all. We
also may be subject to significant damages or an injunction against use of our
products. A successful claim of patent or other intellectual property
infringement against us would have an immediate material adverse effect on our
business and financial condition.


IF WE ARE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY RIGHTS, THIS INABILITY
COULD WEAKEN OUR COMPETITIVE POSITION, REDUCE OUR REVENUES AND INCREASE OUR
COSTS

     Our success depends in large part on our proprietary technology. We rely on
a combination of patent, copyright, trademark and trade secrets, confidentiality
procedures and licensing arrangements to establish and protect our proprietary
rights. We may be required to spend significant resources to monitor and police
our intellectual property rights. If we fail to successfully enforce our
intellectual property rights, our competitive position may be harmed.

     Our pending patent and trademark registration applications may not be
allowed or competitors may successfully challenge the validity or scope of these
registrations. In addition, our patents may not provide us a significant
competitive advantage.


     Other software providers could copy or otherwise obtain and use our
products or technology without authorization. They also could develop similar
technology independently which may infringe our proprietary rights. We may not
be able to detect infringement and may lose a competitive position in the market
before we do so. In addition, competitors may design around our technology or
develop competing technologies. The laws of some foreign countries do not
protect proprietary rights to the same extent as do the laws of the United
States.



     In addition, one of the ways in which we charge for our software is based
on the number of users at a particular site that will be permitted to use our
software. Organizations that have a site license for a fixed number of users for
our products may allow unauthorized use of our software by unlicensed users.
Unauthorized use is difficult to detect and, to the extent that our software is
used without authorization, we may lose potential license fees.


POTENTIAL YEAR 2000 PROBLEMS WITH OUR INTERNAL SYSTEMS, OUR SOFTWARE PRODUCTS OR
THE PRODUCTS WITH WHICH OUR SOFTWARE INTEGRATES COULD ADVERSELY AFFECT OUR
BUSINESS

     We cannot assure you that we will not experience unanticipated negative
consequences relating to problems of computer systems in processing dates after
January 1, 2000. These negative consequences include costs associated with:

     - problems with our products

     - problems of the interaction of our products with other software, and

     - loss of data in our internal systems.


     We have tested our E.piphany E.4 System and our prior products and believe
that they are year 2000 compliant. We have also inquired of significant vendors
of our internal accounting, management and product development systems as to
their year 2000 readiness, and we have also tested our material internal
systems. We believe that, based on these tests and assurances of our vendors, we
will not incur material costs to resolve year 2000 issues for our products and
internal systems. If our tests and inquiries did not uncover all year 2000
problems, we could be exposed to damages resulting from year 2000 failures and

                                       13
<PAGE>   16

claims resulting from damages caused by any incorrect data produced by our
software, whether through a claim of breach of warranty, product defect or
otherwise.


     If our professional services organization does not adequately address
existing year 2000 issues of our customers, or there are preexisting errors in
our customer databases, the usefulness of our software may be impaired. Although
we cannot control the year 2000 compliance of our customers and their
third-party vendors, we may still be subject to claims and liability based on
the fact that our products provided incorrect data. These claims could divert
significant management, financial and other resources and we may not have
adequate commercial insurance to cover these claims.



     If it comes to our attention that there are any year 2000 problems with our
products or that some of our third-party hardware and software used in our
internal systems or our products is not year 2000 compliant, then we will
endeavor to make modifications to our products and internal systems, or purchase
new internal systems, before year 2000 problems arise. Although we do not
believe that the cost of these modifications and replacements, if any, will
materially affect our operating results, we have no other contingency plan to
address effects of year 2000 problems with our products and internal systems. We
may not be able to resolve problems that we discover before we suffer losses. We
cannot assure you that our products and systems will be year 2000 compliant or
that we will not incur material expenses or liability relating to the year 2000
problem.


OUR PRODUCTS ARE NEW, AND IF THEY CONTAIN DEFECTS OR OUR SERVICES ARE NOT
PERCEIVED AS HIGH QUALITY, WE COULD LOSE POTENTIAL CUSTOMERS OR BE SUBJECT TO
DAMAGES


     We recently began shipping our first products in early 1998, and in June
1999, we began shipping our E.piphany E.4 System software. These products are
complex and may contain errors, defects or failures, particularly since they are
new and recently released. In the past we have discovered software errors in
some of our products after introduction. We may not be able to detect and
correct errors before releasing our products commercially. If our commercial
products contain errors, we may be required to:



     - expend significant resources to locate and correct the error



     - delay introduction of new products or commercial shipment of products, or



     - experience reduced sales and harm to our reputation from dissatisfied
       customers.



Our customers also may encounter system configuration problems which require us
to spend additional consulting or support resources to resolve these problems.


     Because our software products are used for important decision-making
processes by our customers, product defects may also give rise to product
liability claims. Although our license agreements with customers typically
contain provisions designed to limit our exposure, some courts may not enforce
all or part of these limitations. Although we have not experienced any product
liability claims to date, we may encounter these claims in the future. Product
liability claims, whether or not successful, could:

     - divert the attention of our management and key personnel from our
       business

     - be expensive to defend, and

     - result in large damage awards.


Our product liability insurance may not be adequate to cover all of the expenses
resulting from a claim. In addition, if our customers do not find our services
to be of high quality, they may elect to use other training, consulting and
product integration firms rather than contract for our services. If customers
are dissatisfied with our services, we may lose revenues.


IF WE NEED ADDITIONAL FINANCING TO MAINTAIN AND EXPAND OUR BUSINESS, FINANCING
MAY NOT BE AVAILABLE ON FAVORABLE TERMS, IF AT ALL

     We expect to incur net losses for the foreseeable future. We may need
additional funds to expand or meet all of our operating needs. If we need
additional financing, we cannot be certain that it will be
                                       14
<PAGE>   17


available on favorable terms, if at all. Further, if we issue common stock after
this offering, stockholders will experience additional dilution. If we need
funds and cannot raise them on acceptable terms, we may not be able to:


     - develop or enhance our products

     - take advantage of future opportunities, or

     - respond to customers and competition.


WE INTEND TO EXPAND OUR INTERNATIONAL SALES EFFORTS BUT DO NOT HAVE SUBSTANTIAL
EXPERIENCE IN INTERNATIONAL MARKETS



     Although our international sales have been immaterial to date, we intend to
expand our international sales efforts in the future. We have very limited
experience in marketing, selling and supporting our products and services
abroad. We plan to expand our international operations in the near future, and
this will require a significant amount of attention from our management and
substantial financial resources. If we are unable to grow our international
operations successfully and in a timely manner, our business and operating
results could be seriously harmed. In addition, doing business internationally
involves greater expense and many additional risks, particularly:



     - unexpected changes in regulatory requirements, taxes, trade laws and
       tariffs



     - differing intellectual property rights



     - differing labor regulations



     - unexpected changes in regulatory requirements



     - changes in a specific country's or region's political or economic
       conditions



     - greater difficulty in staffing and managing foreign operations, and



     - fluctuating exchange rates.


IF WE ACQUIRE ANY COMPANIES OR TECHNOLOGIES IN THE FUTURE, THEY COULD PROVE
DIFFICULT TO INTEGRATE, DISRUPT OUR BUSINESS, DILUTE STOCKHOLDER VALUE AND
ADVERSELY AFFECT OUR OPERATING RESULTS


     We may acquire or make investments in complementary companies, services and
technologies in the future. We have not made any acquisitions or investments to
date, and therefore our ability as an organization to conduct acquisitions or
investments is unproven. If we fail to properly evaluate and execute
acquisitions and investments, they may seriously harm our business and
prospects. To successfully complete an acquisition, we must:



     - properly evaluate the technology



     - accurately forecast the financial impact of the transaction, including
       accounting charges and transactions expenses



     - integrate and retain personnel



     - combine potentially different corporate cultures, and



     - effectively integrate products and research and development, sales,
       marketing and support operations.


     If we fail to do any of these, we may suffer losses or our management may
be distracted from our day-to-day operations. In addition, if we conduct
acquisitions using debt or equity securities, existing stockholders may be
diluted which could affect the market price of our stock.


SEASONAL TRENDS IN SALES OF BUSINESS SOFTWARE MAY AFFECT OUR QUARTERLY REVENUES



     The market for business software has experienced seasonal fluctuations in
demand. The first and third quarters of the year have been typically
characterized by lower levels of revenue growth. We believe that


                                       15
<PAGE>   18

these fluctuations are caused in part by customer buying patterns, which are
influenced by year-end budgetary pressures and by sales force commission
structures. As our revenues grow, we may experience seasonal fluctuations in our
revenues.


BECAUSE SOME EXISTING STOCKHOLDERS WILL TOGETHER OWN 48.6% OF OUR STOCK, THE
VOTING POWER OF OTHER STOCKHOLDERS, INCLUDING PURCHASERS IN THIS OFFERING, MAY
BE LIMITED



     After this offering, it is anticipated that our officers, directors and
five percent or greater stockholders will beneficially own or control, directly
or indirectly, 12,776,300 shares of common stock, which in the aggregate will
represent approximately 48.6% of the outstanding shares of common stock. As a
result, if some of these 12 persons or entities act together, they will have the
ability to control all matters submitted to our stockholders for approval,
including the election and removal of directors and the approval of any business
combination. This may delay or prevent an acquisition or cause the market price
of our stock to decline. Some of these persons or entities may have interests
different than yours. For example, they may be more interested in selling
E.piphany to an acquiror than other investors or may want us to pursue
strategies that are different from the wishes of other investors.



FUTURE SALES OF OUR COMMON STOCK, INCLUDING THOSE PURCHASED IN THIS OFFERING,
MAY DEPRESS OUR STOCK PRICE


     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 fall. Shares issued upon the exercise of outstanding options may also be
sold in the public market. In addition, such sales could create the perception
to the public of difficulties or problems with our products and services. As a
result, 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.


     Upon completion of this offering, we will have outstanding 25,081,790
shares of common stock, assuming no exercise of the underwriters' over-allotment
option and no exercise of outstanding options after June 30, 1999. Of these
shares, the shares sold in this offering are freely tradable. The remaining
21,081,790 shares will become eligible for sale in the public market as follows:

     The above table includes the effect of lock-up arrangements with the
underwriters and us which prevent our directors, officers and other existing
stockholders from selling or otherwise disposing of their shares of common stock
prior to 181 days after this offering. The underwriters may remove these lock-up
restrictions prior to 181 days after this offering without prior notice. In
addition, as of June 30, 1999, we have 2,791,356 outstanding options with a
weighted average exercise price of $2.74. Of these options, 244,167 are vested
and exercisable as of June 30, 1999 and will be resellable 181 days after the
offering.



WE HAVE BROAD DISCRETION TO USE THE OFFERING PROCEEDS AND HOW WE INVEST THESE
PROCEEDS MAY NOT YIELD A FAVORABLE, OR ANY, RETURN FOR US AND YOU MAY LOSE THE
ENTIRE AMOUNT OF YOUR INVESTMENT



     The net proceeds of this offering are not allocated for specific uses other
than working capital and general corporate purposes. Thus, our management has
broad discretion over how these proceeds are used and could spend the proceeds
in ways with which you may not agree. We cannot assure you that the proceeds
will be invested in a way that yields a favorable, or any, return for us.


                                       16
<PAGE>   19


BECAUSE THIS IS OUR INITIAL PUBLIC OFFERING OUR SECURITIES HAVE NO PRIOR MARKET
AND WE CANNOT ASSURE YOU THAT OUR STOCK PRICE WILL NOT DECLINE AFTER THE
OFFERING



     Before this initial public offering of our stock, there has not been a
public market for our common stock and an active public market for our common
stock may not develop or be sustained after this offering. Further, the trading
market price of our common stock may decline below our initial public offering
price. The initial public offering price will be determined by negotiations
between the representatives of the underwriters and us. This price may not
directly relate to our book value, assets, past operating results, financial
condition or other established criteria of value.



WE DO NOT INTEND TO PAY DIVIDENDS, AND YOU WILL NOT RECEIVE FUNDS WITHOUT
SELLING SHARES AND YOU MAY LOSE THE ENTIRE AMOUNT OF YOUR INVESTMENT



     We have never declared or paid any cash dividends on our capital stock and
do not intend to pay dividends in the foreseeable future. We intend to invest
our future earnings, if any, to fund our growth. Therefore, you will not receive
any funds without selling your shares. We further cannot assure you that you
will receive a return on your investment when you sell your shares or that you
will not lose the entire amount of your investment.


AS A NEW INVESTOR YOU WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION


     If you purchase shares of our common stock in this offering, you will
experience immediate and substantial dilution of $8.05 per share in pro forma
net tangible book value. If the holders of outstanding vested options or
warrants exercise their options or warrants, you will experience further
dilution of $0.23 per share.


PROVISIONS IN OUR CHARTER DOCUMENTS AND DELAWARE LAW MAY DELAY OR PREVENT AN
ACQUISITION OF OUR COMPANY


     Our certificate of incorporation and bylaws contain provisions which could
make it harder for a third party to acquire us without the consent of our board
of directors. For example, if a potential acquiror were to make a hostile bid
for us, the acquiror would not be able to call a special meeting of stockholders
to remove our board of directors or act by written consent without a meeting. In
addition, our board of directors have staggered terms which makes it difficult
to remove them all at once. The acquiror would also be required to provide
advance notice of its proposal to remove directors at an annual meeting. The
acquiror also will not be able to cumulate votes at a meeting, which will
require the acquiror to hold more shares to gain representation on the board of
directors than if cumulative voting were permitted.



     Our board of directors also has the ability to issue preferred stock which
would significantly dilute the ownership of a hostile acquiror. In addition,
Section 203 of the Delaware General Corporation Law limits business combination
transactions with 15% stockholders that have not been approved by the board of
directors. These provisions and other similar provisions make it more difficult
for a third party to acquire us without negotiation. These provisions may apply
even if the offer may be considered beneficial by some stockholders.



     Our board of directors could choose not to negotiate with an acquiror that
it did not feel was in the strategic interests of E.piphany. If the acquiror was
discouraged from offering to acquire us or prevented from successfully
completing a hostile acquisition by the antitakeover measures, you could lose
the opportunity to sell your shares at a favorable price.

               YOU SHOULD NOT RELY ON FORWARD-LOOKING STATEMENTS


                     BECAUSE THEY ARE INHERENTLY UNCERTAIN



     You should not rely on forward-looking statements in this prospectus. This
prospectus contains forward-looking statements that involve risks and
uncertainties. We use words such as "anticipates," "believes," "plans,"
"expects," "future," "intends" and similar expressions to identify such
forward-looking statements. You should not place undue reliance on these
forward-looking statements, which apply only as of the date of this prospectus.
Our actual results could differ materially from those anticipated in these
forward-looking statements for many reasons, including the risks faced by us
described above and elsewhere in this prospectus.

                                USE OF PROCEEDS


     The net proceeds to us from the sale of the 4,000,000 shares of common
stock offered by us are estimated to be $36.3 million, after deducting the
underwriting discount, estimated offering expenses and assuming no exercise of
the underwriters' over-allotment option to purchase 600,000 shares from us.


     The principal purposes of this offering are to obtain additional working
capital, to create a public market for our common stock and to facilitate future
access by us to public markets. We expect to use the net proceeds of this
offering for working capital and general corporate purposes. In addition, we may
use a portion of the net proceeds to acquire complementary products,
technologies or businesses; however, we currently have no commitments or
agreements and are not involved in any negotiations to do so. Pending use of the
net proceeds of this offering, we intend to invest the net proceeds in
interest-bearing, investment-grade securities.

                                DIVIDEND POLICY

     We have never declared or paid any dividends on our capital stock. We
currently expect to retain future earnings, if any, for use in the operation and
expansion of our business and do not anticipate paying any cash dividends in the
foreseeable future. Our existing lines of credit prohibit the payment of cash
dividends.

       shares of common stock and the sale of 4,000,000 shares of common stock
       at an assumed initial public offering price of $10.00 per share in this
       offering, less underwriting discounts and commissions and estimated
       offering expenses payable by E.piphany.

                                    DILUTION


     The net tangible book value of our common stock (assuming conversion of all
outstanding shares of our convertible preferred stock on June 30, 1999) was
$12.6 million, or approximately $0.60 per share. Net tangible book value per
share represents the amount of our total tangible assets less total liabilities,
divided by the number of shares of common and convertible preferred stock
outstanding. Dilution in net tangible book value per share represents the
difference between the amount per share paid by purchasers of shares of our
common stock in this offering and the net tangible book value per share of our
common stock immediately afterwards. After giving effect to our sale of
4,000,000 shares of common stock offered by this prospectus at an assumed
initial public offering price of $10.00 per share and after deducting the
underwriting discount and estimated offering expenses payable by us, our net
tangible book value would have been approximately $48.9 million, or $1.95 per
share. This represents an immediate increase in net tangible book value of $1.35
per share to existing stockholders and an immediate dilution in net tangible
book value of $8.05 per share to new investors purchasing shares of common stock
in this offering. The following table illustrates this dilution.

     This table excludes all options and warrants that will remain outstanding

     The following table sets forth, as of June 30, 1999, on the pro forma basis
described above, the differences between the number of shares of common stock
purchased from us, the total price paid and average price per share paid by

initial public offering price, before deducting the underwriting discount and
estimated offering expenses payable by us, of $10.00 per share.

     - the number of shares held by new public investors will be increased to
       4,600,000 or approximately 17.9% of the total number of shares of our
       common stock outstanding after this offering.

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

     The following discussion of our financial condition and results of
operations should be read in conjunction with our financial statements and
related notes. This discussion contains forward-looking statements that involve
risks and uncertainties. Our actual results could differ materially from those
anticipated in these forward-looking statements as a result of certain factors,
including but not limited to, those discussed in "Risk Factors" starting on page
6 and elsewhere in this prospectus.

OVERVIEW


     Our E.piphany E.4 System is an integrated family of software solutions that
companies can deploy to collect and analyze data from their existing software
systems, and from third party data providers, to profile their customers'
characteristics and preferences. Business users use our software to design and
execute marketing campaigns as well as customize products, services and related
customer interactions.



     E.piphany was founded in November 1996. From our founding through the end
of 1997, we primarily engaged in research activities, developing our products
and building our business infrastructure. We began shipping our first software
product and first generated revenues from software license fees, implementation
and consulting fees, and maintenance fees in early 1998. During 1998, we
introduced several other software products, and in June 1999, we shipped our
E.piphany E.4 System software solutions. Although our revenues consistently
increased from quarter to quarter during 1998, we incurred significant costs to
develop our technology and products, to continue the recruitment of research and
development personnel, to build a direct sales force and a professional services
organization, and to expand our general and administrative infrastructure. Our
total headcount has increased from 21 at December 31, 1997 to 115 at June 30,
1999. Our revenues were $3.4 million in 1998 and $5.1 million in the six months
ended June 30, 1999. We had net losses of $3.1 million in 1997, $10.3 million in
1998 and $9.3 million in the six months ended June 30, 1999.


SOURCE OF REVENUES AND REVENUE RECOGNITION POLICY


     We generate revenues principally from licensing our software products
directly to customers and providing related professional services including
implementation, consulting, support and training. Through June 1999,
substantially all of our revenues have been derived from sales within the United
States through our direct sales force. Our license agreements generally provide
that customers pay a software license fee for one or more software solutions for
a specified number of users. The amount of the license fee varies based on which
software solution is purchased, the number of software solutions purchased and
the number of users licensed. Customers can subsequently pay additional license
fees to deploy purchased software solutions to additional users throughout their
organization through standard Internet browsers and to purchase additional
software solutions, which integrate with previously purchased software
solutions. Customers that purchase software solutions receive the software on
compact disc or via electronic methods of delivery.



     Customers generally require consulting and implementation services which
include evaluating their business needs, identifying the data sources necessary
to meet these needs and installing the software solution in a manner which
fulfills their needs. Customers have generally purchased these services directly
from us on either a fixed fee or a time and expense basis. We have historically
supplemented the capacity of our internal services organization by
subcontracting some of these services to third-party consulting organizations,
especially to those organizations with which we have relationships such as KPMG,
Cambridge Technology Partners and Ernst & Young. However, we intend to
increasingly encourage customers to purchase services directly from these third
party consulting organizations. We believe that this would increase the number
of consultants which can provide consulting and implementation services related
to our software products and that it would increase our overall gross margins by
increasing our percentage of license revenue, which has substantially higher
gross margins than services revenue, as a


                                       23
<PAGE>   26


percentage of total revenue. We also believe that it will encourage third party
consulting organizations to sell our software solutions into their customer
base.


     Customers also generally purchase maintenance contracts which provide
software upgrades and technical support over a stated term, generally twelve
months.

     We recognize product license revenues in accordance with the provisions of
American Institute of Certified Public Accounts (AICPA) Statement of Position
97-2, "Software Revenue Recognition." Pursuant to the requirements of Statement
of Position 97-2, we recognize product license revenues when all of the
following conditions are met:

     - we have signed a noncancellable license agreement with the customer

     - we have delivered the software product to the customer

     - the amount of fees to be paid by the customer is fixed or determinable,
       and

     - we believe that collection of these fees is probable.


     To date, when we manage the implementation process for our customers, the
implementation services have been considered essential to the functionality of
the software products. Accordingly, both the product license revenues and
services revenues are recognized in accordance with the provisions of AICPA
Statement of Position 81-1, "Accounting for Performance of Construction Type and
Certain Production Type Contracts." Prior to 1999, we recognized substantially
all of our revenues using the completed contract method as estimates of costs
and efforts necessary to complete the implementation were generally not reliable
given our lack of history with implementing our products. In 1999 and future
periods, we expect to recognize most of our revenues using the percentage of
completion method, and therefore both product license and services revenues are
recognized as work progresses. While our software solutions can generally be
implemented in less than 16 weeks, implementation can take longer depending on
the solution which has been licensed, the number of software solutions licensed,
the complexity of the customer's information technology environment and the
resources directed by customers to the implementation projects. To date, we have
managed the implementation of our solutions for the substantial majority of our
customers. When we subcontract services to third parties, we are responsible for
managing the implementation. To the extent that customers contract directly with
third parties to provide implementation services, we do not manage the
implementation, and license revenues are recognized when the relevant conditions
of Statement of Position 97-2 are met. Some of our contracts provide for the
delivery of unspecified future products over a period of time. Accordingly,
payments received from our customers upon the signing of these agreements are
deferred and the revenues are recognized ratably over the contract period.


     Revenue allocated to maintenance is recognized ratably over the contract
period and revenue allocated to training and other services is recognized as the
services are performed.

COST OF REVENUES AND OPERATING EXPENSES

     Our cost of license revenues primarily consists of license fees due to
third parties for integrated technology. Our cost of services revenues includes
salaries and related expenses for our implementation, consulting support and
training organizations, costs of subcontracting to third parties to provide
consulting services to customers and an allocation of facilities, communications
and depreciation expenses. Our operating expenses are classified into three
general categories: sales and marketing, research and development, and general
and administrative. We classify all charges to these operating expense
categories based on the nature of the expenditures. We allocate the costs for
overhead and facilities to each of the functional areas that use the overhead
and facilities services based on their headcount. These allocated charges
include facility rent for corporate offices, communication charges and
depreciation expenses for office furniture and equipment.


     Software development costs incurred prior to the establishment of
technological feasibility are included in research and development costs as
incurred. Since license revenues from our software solutions

                                       24
<PAGE>   27


are not recognized until after technological feasibility has been established,
software development costs are not generally expensed in the same period in
which license revenues for the developed products are recognized.



     We had 115 full-time employees as of June 30, 1999 and intend to hire a
significant number of employees in the future. This expansion places significant
demands on our management and operational resources. To manage rapid growth and
increased demand, we must continue to invest in and implement additional
operational systems, procedures and controls.


RESULTS OF OPERATIONS

     SIX MONTHS ENDED JUNE 30, 1999 AND 1998

REVENUES

     Total revenues increased to $5.1 million for the six months ended June 30,
1999, from $0.9 million for the six months ended June 30, 1998. This rapid
growth in revenues reflects our relatively early stage of development, and we do
not expect revenues to increase at the same rate in the future. For the six
months ended June 30, 1999, Sallie Mae, CSAA, KPMG and Fair, Isaac accounted for
20%, 13%, 11% and 11% of our total revenues, respectively. For the six months
ended June 30, 1998, Autodesk, Visio and Macromedia accounted for 57%, 21% and
16% of our total revenues, respectively.


     Product license revenues increased to $2.9 million, or 57% of total
revenues, for the six months ended June 30, 1999 from $0.5 million, or 62% of
total revenues, for the six months ended June 30, 1998. The increase in dollar
amount of product license revenues was due to both an increase in the number of
licenses sold and the average size of the licenses, and resulted primarily from
the growth of our direct sales force and the introduction and shipment of new
products. Product license revenues declined as a percentage of total revenues
primarily because of increased maintenance revenues due to the growth in our
customer base.


     Services revenues increased to $2.2 million, or 43% of total revenues, for
the six months ended June 30, 1999 from $0.3 million, or 38% of revenues, for
the six months ended June 30, 1998. The increase was primarily attributable to
increased implementation and consulting services performed in connection with
increased license sales and to maintenance contracts sold to E.piphany's new
customers. Because services revenues have substantially lower margins relative
to product license revenues, to the extent that services revenues become a
greater percentage of our total revenues, our overall gross profits will
decline.

COST OF REVENUES

     Total cost of revenues increased to $2.5 million for the six months ended
June 30, 1999 from $0.4 million for the six months ended June 30, 1998.

     Cost of product license revenues consists primarily of license fees paid to
third parties under technology license arrangements and have not been
significant to date.


     Cost of services revenues consists primarily of the costs of consulting and
customer service and support. Cost of services revenues increased to $2.5
million, or 113% of services revenues, for the six months ended June 30, 1999
from $0.4 million, or 112% of services revenues, for the six months ended June
30, 1998. The increase in cost of services revenues in absolute dollars resulted
primarily from the hiring of additional employees and subcontracting with
third-party integrators to support increased customer demand for consulting
services. Cost of services revenues has exceeded services revenues due to the
rapid growth of our services organization from 5 employees at June 30, 1998 to
28 employees at June 30, 1999 and our investment in experienced management in
anticipation of future revenue growth.


                                       25
<PAGE>   28

OPERATING EXPENSES

Research and Development


     Research and development expenses consist primarily of personnel and
related costs associated with our product development efforts. Research and
development expenses increased to $2.9 million for the six months ended June 30,
1999 from $1.6 million for the six months ended June 30, 1998. The increase in
absolute dollars was primarily due to an increase in the number of employees
engaged in research and development from 18 employees as of June 30, 1998 to 36
employees as of June 30, 1999. Research and development expenses as a percentage
of total revenues decreased from 190% to 56% due primarily to growth in our
revenues. We believe that investments in product development are essential to
our future success and expect that the absolute dollar amount of research and
development expenses will increase in future periods.


Sales and Marketing


     Sales and marketing expenses consist primarily of employee salaries,
benefits and commissions, and the costs of trade shows, seminars, promotional
materials and other sales and marketing programs. Sales and marketing expenses
increased to $6.4 million for the six months ended June 30, 1999 from $2.3
million for the six months ended June 30, 1998. Sales and marketing expenses as
a percentage of total revenues decreased from 262% to 124% due primarily to
growth in our revenues. The increase in absolute dollars was primarily
attributable to an increase in the number of direct sales, pre-sales support and
marketing employees from 16 employees as of June 30, 1998 to 38 employees as of
June 30, 1999. We expect that the absolute dollar amount of sales and marketing
expenses will continue to increase due to the planned growth of our sales force,
including the establishment of sales offices in additional domestic and
international locations including Europe and Asia, and due to expected
additional increases in advertising and marketing programs and other promotional
activities.


General and Administrative

     General and administrative expenses consist primarily of employee salaries
and related expenses for executive, finance and administrative personnel.
General and administrative expenses increased to $1.3 million for the six months
ended June 30, 1999 from $0.6 million for the six months ended June 30, 1998.
General and administrative expenses as a percentage of total revenues decreased
from 71% to 25% due primarily to growth in our revenues. The increase in
absolute dollars was primarily attributable to increased salary and related
expenses in the executive, finance and administrative functions to manage our
growth. We expect general and administrative expenses to increase in absolute
dollars in future periods.

Stock-Based Compensation

     Stock-based compensation consists of amortization of deferred compensation
in connection with stock option grants and sales of stock to employees at
exercise or sales prices below the deemed fair market value of our common stock
and compensation related to equity instruments issued to non-employees for
services rendered. In 1998 and the six months ended June 30, 1999, we recorded
aggregate deferred compensation of $5.9 million related to stock-based
compensation to employees. This amount is being amortized over the respective
vesting periods of these equity instruments in a manner consistent with
Financial Accounting Standards Board Interpretation No. 28. Of the total
deferred compensation, $1.3 million was amortized in the six months ended June
30, 1999. We expect amortization of approximately $1,182,000, $1,525,000,
$794,000, $315,000, and $26,000 in the second half of 1999, the years ended
December 31, 2000, 2001, 2002, and the first half of 2003, respectively. Total
stock-based compensation was $1.6 million for the six months ended June 30,
1999. See Note 6 to Notes to Financial Statements.

<PAGE>   29

INTEREST INCOME, NET

     The decrease in interest income, net of interest expense, for the six
months ended June 30, 1999 was not significant when compared to the same period
in the prior year.

     YEARS ENDED DECEMBER 31, 1998 AND 1997

REVENUES

     Our total revenues were $3.4 million in 1998 and were comprised of the
first commercial sales of software products and related services fees from
implementation, training and support. Product license revenues were $2.2 million
in 1998. Services revenues were $1.2 million in 1998. For 1998, product license
revenues and services revenues accounted for 66% and 34% of revenues,
respectively. We did not recognize any revenues in 1997.

     In 1998, Autodesk, Charles Schwab, Hewlett-Packard, KPMG and Macromedia,
accounted for 30%, 17%, 16%, 11% and 11% of total revenues, respectively.

     Cost of revenues was $1.4 million in 1998. Cost of services revenues as a
percentage of services revenues was 120%. The increase in cost of services
revenues in 1998 resulted primarily from the hiring of employees and, to a
lesser extent, the use of third-party integrators to support customer demand for
consulting and maintenance services. We did not have any revenues in 1997 and
thus had no cost of revenues in 1997.

OPERATING EXPENSES

Research and Development

     Research and development expenses increased to $3.8 million in 1998 from
$1.6 million in 1997. The increase in research and development expenses was
related primarily to an increase in the number of employees engaged in research
and development to support the development of new products.

Sales and Marketing

     Sales and marketing expenses increased to $6.5 million in 1998 from $1.2
million in 1997. The increase in sales and marketing expenses resulted primarily
from building a direct sales force and investing in sales and marketing
infrastructure which included significant personnel-related expenses, recruiting
fees, travel expenses, and related facility and equipment costs, as well as
increased marketing activities, including trade shows, public relations, direct
mail campaigns and other promotional expenses.

General and Administrative


     General and administrative expenses increased to $1.5 million in 1998 from
$0.4 million in 1997. The increase in dollar amount of general and
administrative expenses resulted primarily from the addition of executive,
finance and administrative personnel to support the growth of our business.


Stock-Based Compensation

     In 1998, stock-based compensation consisted of amortization of deferred
compensation in connection with certain stock option grants and sales of stock
to employees at exercise or sales prices below the deemed fair market value of
our common stock and compensation related to equity instruments issued to
non-employees. We recorded aggregate deferred compensation of $3.2 million in
1998 related to stock transactions with employees. Of the deferred compensation,
$0.7 million was amortized in 1998. Total stock-based compensation was $0.8
million in 1998. See Note 6 to Notes to Financial Statements.

<PAGE>   30

INTEREST INCOME, NET

     Interest income, net of interest expense, increased to $0.3 million from
$0.1 million as a result of higher interest income due to higher average cash
balances related to capital financing activities, partially offset by higher
interest expense due to bank borrowings.

PROVISION FOR INCOME TAXES

     From inception through December 31, 1998, we incurred net losses for
federal and state tax purposes and have not recognized any tax provision or
benefit. As of December 31, 1998, we had $11.7 million of federal and state net
operating loss carry forwards to offset future taxable income. The federal net
operating loss carry forwards begin to expire on varying dates beginning in 2012
through 2018 and the state operating loss carry forwards begin to expire in
2004. Given our limited operating history, our losses incurred to date and the
difficulty in accurately forecasting our future results, management does not
believe that the realization of the related deferred income tax asset meets the
criteria required by generally accepted accounting principles. Therefore, we
have recorded a 100% valuation allowance against these tax loss carryforwards.
See Note 7 of Notes to Financial Statements.

QUARTERLY RESULTS OF OPERATIONS

     The following table sets forth, for the periods presented, certain
unaudited quarterly financial results for the six quarters ended June 30, 1999.
The statement of operations data has been derived from our unaudited financial
statements. In management's opinion, these statements have been prepared on
substantially the same basis as the audited financial statements and include all
adjustments, consisting only of normal recurring adjustments, necessary for a
fair presentation of the financial information for the periods presented. This
information should be read in conjunction with the financial statements and
notes thereto included elsewhere in this prospectus. We have experienced and
expect to continue to experience fluctuations in operating results from quarter
to quarter. Historical operating results are not necessarily indicative of the
results that may be expected for any future period.

     Our quarterly revenues increased throughout 1998 and the first two quarters
of 1999 primarily as a result of the introduction of our first commercially
available software products and the growth of our direct sales force. Cost of
revenues has increased in each of these quarters as a result of the hiring of
employees and the cost of subcontracting with third-party integrators to support
customer demand for consulting and maintenance services. Total operating
expenses increased in each quarter primarily due to increased expenses
associated with building a sales and marketing infrastructure including the
development of a direct sales force, increased spending on research and
development to support new product introductions and an increase in general and
administrative expenses to manage our expanding operations.


     Services revenues as a percentage of total revenues has varied
significantly from quarter to quarter due to our relatively early stage of
development. The relative amount of services revenues as compared to license
revenues has varied based on the volume of license fees for software solutions
compared to the volume of license fees for additional users, which generally do
not require services. In addition, the amount of services we provide for a
software solution can depend in large part on the solution which has been
licensed, the complexity of the customers' information technology environment,
the resources directed by customers to their implementation projects, the number
of users licensed and the extent to which our third-party integrators provide
services directly to customers. Services revenues as a percentage of total
revenues has increased for each of the last two quarters primarily due to growth
of our new customer base which has resulted in a higher percentage of new
software solution license sales compared to additional user license sales.



     Cost of services revenues as a percentage of total revenues has increased
each of the last two quarters, primarily as a result of the increased services
revenues as a percentage of total revenues. Cost of services revenues can also
depend on the extent to which we subcontract to third party organizations to
provide services to our customers, which is generally more expensive than
performing such services with internal resources. Our operating expenses as a
percentage of total revenues have generally decreased from quarter to quarter
due to our relatively early stage of development and our historical rapid
revenue growth.


     Although we have a limited operating history, we believe that quarterly
operating results may experience seasonal fluctuations in the future. For
instance, quarterly results may fluctuate based on client calendar year
budgeting cycles, slow summer purchasing patterns in Europe and our compensation
policies that tend to compensate sales personnel, typically in the latter half
of the year, for achieving annual quotas.

LIQUIDITY AND CAPITAL RESOURCES

     We have funded our operations to date primarily through private placements
of equity securities and, to a lesser extent, debt financing and revenues.
Through June 30, 1999, we have raised $32.5 million through equity financing.


     Under a senior credit facility, we maintain a $1.0 million revolving line
of credit with Silicon Valley Bank that expires December 1, 1999 and bears
variable interest at the bank's prime rate, currently 8.0%. As of June 30, 1999,
we had not borrowed against this line of credit. We also have a $3.0 million
term loan under this senior credit facility that is repayable ratably over a 36
month period beginning March 1, 2000. The term loan bears variable interest at
the bank's prime rate plus 0.5%, currently 8.5%. As of June 30, 1999, we had
borrowed $3 million against this term loan. Both of these loans are secured by
essentially all of our assets.



     In addition, we have a subordinated convertible debt facility with Comdisco
under which we are entitled to borrow up to $10.0 million, of which $5.0 million
is currently outstanding, over 42 months beginning June 1999 at a fixed interest
rate of 10.0%. All borrowings under the subordinated facility are secured by
essentially all of our assets after the rights of senior creditors, and we
cannot maintain more than $5.0 million of senior debt without approval of the
lender. We also have a $2.0 million equipment lease line with Comdisco. Under
the equipment lease line, we are entitled to lease equipment with payment terms
extending over 42 months. The ability to lease new equipment expires on May 31,
2000


                                       30
<PAGE>   33


and borrowings bear interest at 8.5% for the first six months of the lease. We
did not have any obligations under this lease line as of June 30, 1999. See Note
3 of Notes to Financial Statements.


     Net cash used in operating activities totaled $2.9 million in 1997, $8.7
million in 1998 and $7.2 million during the six months ended June 30, 1999. Cash
used in operating activities for each period resulted primarily from net losses
in those periods.

     Net cash used in investing activities totaled $0.4 million in 1997, $1.1
million in 1998 and $0.8 million for the six months ended June 30, 1999. The
increases in each period resulted primarily from the purchase of furniture and
equipment, consisting largely of computer servers and workstations.

     Net cash provided by financing activities totaled $3.6 million in 1997,
$23.0 million in 1998 and $14.3 million for the six months ended June 30, 1999.
The increases in each period resulted primarily from the net proceeds from
issuances of convertible preferred stock, the issuance of subordinated
convertible debt, and bank borrowings.

     As of June 30, 1999, our principal sources of liquidity included $19.9
million of cash and cash-equivalents. We anticipate a substantial increase in
our capital expenditures and lease commitments consistent with anticipated
growth in operations, infrastructure and personnel. See Notes 3 and 4 of Notes
to Financial Statements.

     We believe that the net proceeds from this offering, combined with current
cash balances and short-term investments, will be sufficient to meet our
anticipated liquidity needs for working capital and capital expenditures for at
least 12 months from the date of this prospectus. Our forecast of the period of
time through which our financial resources will be adequate to support
operations is a forward-looking statement that involves risks and uncertainties,
and actual results could vary materially as a result of the factors described
above.


     After the next 12 months, we expect to continue to incur net losses for the
foreseeable future and we may need additional funds to expand or meet all of our
operating needs.



     If we require additional capital resources to grow our business internally
or to acquire complementary technologies and businesses at any time in the
future, we may seek to sell additional equity or debt securities or secure an
additional bank line of credit. The sale of additional equity or convertible
debt securities could result in additional dilution to our stockholders. We
cannot assure you that any financing arrangements will be available in amounts
or on terms acceptable to us.


YEAR 2000 ISSUES

     We are aware of the issues surrounding the year 2000 and problems relating
to computers and computer software incorrectly distinguishing between 21st and
20th century dates. Year 2000 issues could affect both our products and services
as well as our internal management control systems.

     With respect to our products, we have designed our E.piphany E.4 System and
other products to be year 2000 compliant. We have tested our E.piphany E.4
System and based on these tests, as well as input from our customers using the
pre-release test version of the software, believe our software is year 2000
compliant. We have tested our prior products only to a limited extent. Based on
these tests and input from our customers, we believe that the prior products are
also year 2000 compliant. We therefore do not expect to expend significant
resources to resolve year 2000 errors in our products. However, we cannot be
certain that our test procedures, particularly the limited tests performed on
our prior products, will uncover all possible year 2000 errors in our products.
In some cases, we have warranted to our customers that our products are year
2000 compliant. If our tests and design measures have failed to discover and
resolve all year 2000 problems in our products, we could be liable to customers
for breach of warranty, product defects or otherwise.


     In addition, many of the enterprise databases and web browsers with which
our software interacts may not be year 2000 compliant. If our customers'
databases are not year 2000 compliant, our internal professional services
organization may need to address these existing year 2000 issues. Also,
preexisting

                                       31
<PAGE>   34


data in our customers' databases accessed by our software may already contain
year 2000 errors. Our professional services organization may not be able to
adequately address existing year 2000 issues, or there may be preexisting errors
in our customers' databases. Although we cannot control the year 2000 compliance
of our customers and their third-party vendors, we may still be subject to
claims and liability based on the fact that our products provided incorrect
data. These claims could divert significant management, financial and other
resources and we may not have adequate commercial insurance to cover these
claims.


     With respect to our information technology and management functions, we
have inquired of the year 2000 compliance of our material hardware and software
vendors related to internal accounting, management and product development. We
have also tested our systems, but only to a very limited extent. Based on the
representations of our vendors and the internal tests we have conducted, we do
not believe we will incur material losses relating to upgrade and replacement of
our systems or from failure of our systems.


     We intend to implement a new accounting and management reporting system in
late 1999 for business reasons unrelated to year 2000. We have been assured that
our new system is also year 2000 compliant by the vendor. If any of our vendors'
representations regarding their products are not accurate, or if we encounter
unknown year 2000 problems relating to the interaction of our systems, we could
incur significant expenses to resolve these issues or damages resulting from a
failure of our systems to perform correctly. For example, if our accounting
system fails to properly record our transactions, we would need to devote staff
or hire a third-party to correct the problem, could lose important data and
would have difficulty planning and reporting without accurate financial
information.



     In the event we discover year 2000 problems in our products or internal
systems, we will endeavor to resolve these problems by making modifications to
our products or systems or purchasing new systems, on a timely basis. However,
we have no other contingency plan to address the effect of year 2000 problems
with our products and internal systems. In addition, the effect of year 2000 on
our customers generally, or on our banks, stock markets and other infrastructure
functions is unknown. We cannot assure you that our products and systems will be
year 2000 compliant or that we will not incur material expenses or liability
relating to the year 2000 problem. Our costs of year 2000 compliance to date
have not been material and we do not anticipate material year 2000 compliance
costs in the future.


MARKET RISK

     The following discusses our exposure to market risk related to changes in
interest rates, equity prices and foreign currency exchange rates. This
discussion contains forward-looking statements that are subject to risks and
uncertainties. Actual results could vary materially as a result of a number of
factors including those set forth in the risk factors section of this
prospectus.

Foreign Currency Exchange Rate Risk


     To date, all of our recognized revenues have been denominated in U.S.
dollars and primarily from customers in the United States, and our exposure to
foreign currency exchange rate changes has been immaterial. We expect, however,
that future product license and services revenues may also be derived from
international markets and may be denominated in the currency of the applicable
market. As a result, our operating results may become subject to significant
fluctuations based upon changes in the exchange rates of certain currencies in
relation to the U.S. dollar. Furthermore, to the extent that we engage in
international sales denominated in U.S. dollars, an increase in the value of the
U.S. dollar relative to foreign currencies could make our products less
competitive in international markets. Although we will continue to monitor our
exposure to currency fluctuations, and, when appropriate, may use financial
hedging techniques in the future to minimize the effect of these fluctuations,
we cannot assure you that exchange rate fluctuations will not adversely affect
our financial results in the future.

Interest Rate Risk


     As of June 30, 1999, we had cash and cash equivalents of $19.9 million
which consist of cash and highly liquid short-term investments. Our short-term
investments will decline in value by an immaterial amount if market interest
rates increase, and, therefore, our exposure to interest rate changes has been
immaterial. Declines of interest rates over time will, however, reduce our
interest income from our short-term investments.



     As of June 30, 1999, we had total short term and long term debt outstanding
of $432,000 and $2,979,000, respectively, which contain interest rates that are
tied to the prime rate. Therefore, we are subject to exposure to interest rate
risk for these borrowings based on fluctuations in the prime rate. Based upon
the outstanding indebtedness under these arrangements, an increase in the prime
rate of .5% would cause a corresponding increase in our annual interest expense
of approximately $170,000.


RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 133, "Accounting for
Derivative Instruments and Hedging Activities," which requires companies to
record derivative financial instruments on their balance sheets as assets or
liabilities, measured at fair value. Gains or losses resulting from changes in
the values of those derivatives would be accounted for depending on the use of
the derivative and whether it qualifies for hedge accounting. The key criterion
for hedge accounting is that the hedging relationship must be highly effective
in achieving offsetting changes in fair value or cash flows. In June 1999, the
FASB issued SFAS No. 137, "Accounting For Derivative Instruments and Hedging
Activities -- Deferral of the Effective Date of FASB Statement No. 133," which
amends SFAS No. 133 to be effective for all fiscal quarters or all fiscal years
beginning after June 15, 2000, or January 1, 2001 for us. This statement will
not have a material impact on the financial condition or results of our
operations.

     In December 1998, the AICPA issued Statement of Position (SOP) 98-9,
"Modification of SOP 97-2, Software Revenue Recognition, with Respect to Certain
Transactions." SOP 98-9 amends SOP 97-2 and SOP 98-4 by extending the deferral
of the application of some provisions of SOP 97-2 amended by SOP 98-4 through
fiscal years beginning on or before March 15, 1999. All other provisions of SOP
98-9 are effective for transactions entered into in fiscal years beginning after
March 15, 1999. We do not anticipate that this statement will have a material
adverse impact on our statement of operations.

                                    BUSINESS

E.PIPHANY OVERVIEW


     We develop and market software that enables companies to establish,
maintain and continually improve customer relationships across both Internet and
traditional sales, marketing and distribution channels. Our E.piphany E.4 System
is an integrated family of software solutions that companies can deploy to
collect and analyze data from their existing software systems, and from third
party data providers, to profile their customers' characteristics and
preferences. Business users can then act on this information by using our
software to design and execute marketing campaigns as well as customize
products, services and related customer interactions.


INDUSTRY BACKGROUND


     The rapid growth of the Internet is fundamentally changing the way
businesses interact with their customers and suppliers. Consumers can use the
Internet to more quickly evaluate products and prices from a wide range of
vendors without regard to geographical constraints. At the same time, companies
across a variety of industries are using the Internet to redefine the way that
goods and services are marketed, sold and distributed. International Data
Corporation estimates the number of worldwide Internet users grew from 21
million in 1995 to 159 million in 1998 and will reach 510 million in 2003.



     To remain competitive in this dynamic business environment, many companies
are seeking to increase the longevity and profitability of their customer
relationships. We believe companies that improve their understanding of their
customers can gain the loyalty of their most profitable customers by customizing
products, services and related interactions based on each of those customers'
characteristics and preferences. Furthermore, when companies understand
individual customers, they can market complementary products, known as
"cross-selling," or market higher-end products, known as "up-selling." These
companies can also use their knowledge of the correlation between customer
characteristics and preferences to better market to potential new customers.
Finally, companies can also use customer preference information to better
anticipate customer demand and optimize their processes for fulfilling customer
orders. For example, a company that identifies that many customers prefer a
particular product can increase inventories of that product to meet demand and
decrease inventories of other products that are not in demand.



     Over the past two decades, companies have invested in software applications
that reduce costs by automating business processes. AMR Research, an industry
and market analysis firm, estimates that, from 1995 through 1998, companies have
spent more than $56 billion on industrial enterprise applications software to
automate such transaction-oriented functions as sales, support, manufacturing,
distribution and finance. More recently, companies have begun investing in
Internet infrastructure software, including systems that enable commercial
transactions over the Web, as well as systems that monitor and track customers'
behavior on Web sites. Many companies also continue to operate older,
custom-built systems that automate critical business processes, such as order
processing and accounting. All of these applications have allowed companies to
collect and store enormous volumes of customer data, which is often augmented by
marketing data from third-party data providers.



     Despite the vast amounts of data generated, these applications remain
focused on automating business processes, rather than analyzing data to help
companies better understand their customers. Moreover, because this data resides
in disparate computer systems across each company or is delivered from third
parties, integrating and analyzing this data to provide a comprehensive view of
the customer is a significant challenge. For example, many companies' Internet
commerce systems operate independently of systems that automate their
traditional sales channels and fulfillment processes. To analyze and act on
disparate corporate data, many companies have attempted to integrate multiple
software tools designed to either extract data from various software systems,
store it in a central repository, analyze the data or manage marketing
campaigns. Many of these internally developed software systems require
substantial amounts of time to integrate, are expensive to deploy and maintain,
and are not designed to solve specific business


                                       34
<PAGE>   37


problems in areas such as sales, marketing, finance and Internet commerce.
Finally, these software systems often have complex user interfaces and may not
be accessible to all business users across the enterprise.



     To enable all employees or selected customers of a company to analyze and
act on meaningful customer information located throughout the organization,
companies need new software solutions. These software solutions should be:



     - Focused on establishing, maintaining and improving customer
       relationships. Software should allow companies to identify and
       differentiate their current and potential customers and act on that
       knowledge to provide products, services and related interactions
       customized to each customer's preferences.



     - Deployable to all business users and interactions with
       customers. Software should be designed to offer the ease of use and
       availability of the Web to enable all business users, not just
       information technology professionals and specialized analysts, to access,
       understand and act on customer information. Additionally, software should
       easily integrate with companies' Internet infrastructure software to help
       companies understand customer behavior on websites, market through
       websites or e-mail and enable customers to query corporate information
       sources via the Web.



     - Packaged to offer faster and less expensive implementation. Software
       should minimize the time and expense of software deployment and
       maintenance by including in a single integrated system all of the
       technologies required to extract, store, analyze and act on customer
       data. In addition, the software should be designed to solve specific
       business problems in areas such as sales, marketing, finance and Internet
       commerce.


THE E.PIPHANY SOLUTION


     Our software enables companies to establish, maintain and continually
improve customer relationships across both Internet and traditional sales,
marketing and distribution channels. Companies can use the E.piphany E.4 System
to profile customers' characteristics and preferences by collecting and
analyzing data from their existing software systems and third party data
providers. Business users can then act on this information by using our software
to design and execute marketing campaigns as well as customize products,
services and related customer interactions. Our professional services
organization implements our E.piphany E.4 System for our customers and also
provides related consulting and training. We believe that our software is
differentiated by its combination of the following characteristics:



     Software designed to establish, maintain and improve customer
relationships. Our software helps companies establish, maintain and improve
customer relationships by:



     - Identifying customers. Our software enables companies to better identify
       their customers by aggregating and analyzing data from existing software
       systems as well as from third-party data providers.



     - Differentiating customers. Our software allows companies to differentiate
       their customers by analyzing customer groups by demographics,
       profitability, length of sales cycle, cross-sell success rates and other
       company-defined criteria.



     - Interacting with customers more personally. Our software helps companies
       to extend customer information to all employees that interact with
       customers as well as integrate this information with Internet
       infrastructure software that generates Web pages and e-mail. Moreover,
       our software can be used to design and execute marketing campaigns that
       tailor marketing messages to each customer based on his or her specific
       characteristics and preferences.



     - Customizing products, services and fulfillment. Our software helps
       companies collect and analyze the data required to customize products,
       services and related interactions based on customer characteristics and
       preferences. In addition, companies can use our software to better
       anticipate customer demand and to better manage their processes for
       fulfilling orders in a more efficient manner.

                                       35
<PAGE>   38


     Web-based design to promote ease of use and wide-scale deployment to
business users. Our software is easy-to-use and is accessed by business users
across a corporate network or the Internet using only a Web browser, such as
Microsoft Internet Explorer. The software is installed by the customer in a
central location, either on the customer's own computer servers or on those of a
third-party hosting service. This Web-based design does not require our software
to be installed on each user's computer, which reduces the costs of deploying
and maintaining software.



     Packaged software for faster and less expensive implementation. Our
software is packaged to combine technologies required to collect and analyze
customer data or manage marketing campaigns and is designed to solve specific
business problems in areas such as sales, marketing, finance and Internet
commerce. This eliminates the need for a company to integrate multiple software
tools from various vendors or develop custom software to solve specific business
problems. Our software solutions can generally be implemented in 16 weeks or
less.


E.PIPHANY STRATEGY


     Our objective is to be the leading provider of software that enables
companies to establish, maintain and continually improve customer relationships
across both Internet and traditional sales, marketing and distribution channels.
Key elements of our strategy include:



     Extend the breadth and depth of our product offerings. We intend to
continue to invest in research and development to build new software to solve a
greater range of problems for our customers. In particular, we intend to expand
our software offerings for Internet commerce and to develop new software that
solves additional problems in fulfillment, logistics and operations. We believe
that maintaining and enhancing our products is important to our ability to
expand our market share, retain existing customers and acquire new customers.



     Develop industry-specific software products. In the future, we plan to
offer versions of our software designed specifically for industries such as
financial services, high technology, healthcare, telecommunications and
automobile manufacturing. We intend to use the industry expertise of our
professional services organization and our existing and future partners to help
us identify business problems specific to these industries and help us design
our software accordingly.



     Increase market penetration by expanding our sales and distribution
capabilities. In addition to growing our direct sales force, we have developed a
limited number of contractual relationships with consultants, systems
integrators and resellers that we believe will allow us to extend our sales
presence. We intend to use these relationships to support sales and help us
develop new E.piphany E.4 System software solutions. We also intend to build our
international presence through relationships with systems integrators that have
a strong international presence, such as KPMG, in addition to increasing the
size of our direct sales force.



     Offer our software through application service providers. In addition to
licensing our software directly to end-users, we intend to offer our software
through multiple Internet-based applications service providers that will host
our software on their own servers and allow customers to utilize that software
over the Internet for a fee. Through these relationships, the applications
service provider will pay us fees for the right to host our applications for its
customers. We currently have a contractual relationship with Exactis.com -- a
provider of e-mail application services -- under which Exactis.com hosts our
software solutions as a part of its service offering. In the future, we intend
to partner with additional application service providers. We believe that the
application service provider option will be particularly attractive to pure
Internet commerce companies, as well as mid-sized companies that typically have
limited internal information technology resources.

PROFESSIONAL SERVICES


     Our professional services organization plays an integral role in
implementing our software for our customers as well as supporting and training
our customers. We believe that providing a high level of customer service and
technical support is critical to the satisfaction of our customers and our own
success. As of June 30, 1999, our professional services staff consisted of 28
employees. Our professional services offerings include:



     Consulting and implementation services. We offer consulting and
implementation services focused on configuring and implementing our software
solutions to meet each of our customers' unique needs. These services are
delivered primarily by our internal consulting specialists, but also by
third-party consultants. When we work with third-party consultants we typically
subcontract these consultants or enter into contracts with these consultants to
collaborate on specific projects. We believe that our consulting services
enhance the quality of our software solutions, accelerate the implementation and
share best business practices with client project teams.



     Maintenance services. We provide our customers with extensive maintenance
services including telephone support, Web-based support and updates to our
products and documentation. We enter into maintenance contracts separate from
our product license agreements. Fees are typically 15 to 20% of the license fees
for the associated software products.



     Training services. We offer extensive training programs to our customers
and partners to accelerate the implementation and adoption of our solutions by
the users within a company. Fees for our training services are typically charged
separately from our software license fees and consulting fees.



     In addition to implementing our software and supporting our customers, our
professional services organization works closely with our internal research and
development organization to design new E.piphany E.4 System software solutions.
Experience gained by our consultants through repeated implementation of our
products is routinely conveyed to our research and development staff. Our
research and development staff then uses this experience to design new features
into new releases of our software. To promote this interaction, we have located
our professional services organization together with our research and
development organization, and we have created a staff exchange program between
the two parts of our firm.

E.PIPHANY E.4 SYSTEM TECHNOLOGY


GRAPHIC


     Our E.piphany E.4 System includes the E.piphany E.4 System software
platform. This software platform enables our software to extract, manage and
analyze data from existing systems for each of our software solutions. This
software platform allows our internal research and development organization and
partners to rapidly build and deploy new software as market opportunities arise,
without re-developing and configuring the underlying software platform. The
major elements of our E.piphany E.4 System software platform include:



     EpiCenter. EpiCenter is the software technology we developed for storing
and managing data. Our software solutions access EpiCenter to retrieve the data
that they require to perform their analysis. Key functional elements of
EpiCenter include:



     - Adaptive Schema Generator. The Adaptive Schema Generator is software
       technology that we have developed and market as a part of our E.piphany
       E.4 System. It automatically reconfigures EpiCenter, based on high-level
       specifications, each time a customer's software solutions are modified.
       This technology enables rapid customization of our products to meet the
       specific and dynamic business needs of our customers and allows system
       administrators to avoid having to manage complex data storage design
       tasks.



     - Metadata integration. All of the components of our E.piphany E.4 System
       are integrated through our metadata, which is a high-level,
       software-based description of a customer's E.piphany E.4 System and the
       data which resides in that system. As a result, when new data elements
       are added to any software component of a customer's E.piphany E.4 System,
       all other software components are able to recognize the change and adapt
       accordingly.



     - Accelerators. We have integrated into our E.piphany E.4 System
       mathematical formulas called accelerators that improve the performance of
       our software by pre-computing some information, creating special indices
       and providing "hints" to the system on how to optimize the processing of
       user queries.



     Data extraction and transformation. E.piphany's E.4 System offers a
powerful approach to extracting data from various sources and transforming that
data before loading it into EpiCenter. Central to this capability are our
Packaged Semantic Transformations, which are rules that change customer data
into a format well-suited for data analysis by business users.


                                       40

     Application server. Our application server is the software technology we
developed to manage the mathematical formulas that are used to analyze data in
response to user queries. In addition, the application server generates the user
interface that end-users interact with through their Web browsers.


RELATIONSHIPS AND ALLIANCES


     An important element of our strategy is to establish relationships and
alliances to assist us in marketing, selling and implementing our software
solutions. These relationships and alliances fall into the following four
categories:



     Consulting and implementation relationships. We have a contractual
relationship with Marketing 1:1 -- a marketing consulting firm -- under which
they co-market and promote our software. We have entered into subcontracting
engagement letters with Cambridge Technology Partners, Ernst & Young and KPMG
under which they provide installation services for our products to our
customers. In order to improve their opportunity to generate service fees from
our customers, each of these partners has committed resources to training their
consultants on our products, co-marketing our products with their services and
incorporating our products into their customer relationship management market
strategies. In addition, Cambridge Technology Partners, KPMG and Marketing 1:1
are investors in our company. We believe these relationships will help enable
the rapid adoption and deployment of our software and expand the capabilities of
our software to target specific industries.



     Platform relationships. To help ensure that our products are based on
industry standards and take advantage of current and emerging technologies, we
have formed relationships with vendors of software and hardware technology
platforms. We currently maintain platform relationships with Hewlett-Packard,
Microsoft, Oracle and Sun Microsystems. These companies voluntarily provide us
with early releases of new technology platforms, education related to those
platforms and limited access to these vendors' technical resources to facilitate
adoption of their technology. As a result, we are able to more easily integrate
our products with these vendors' platforms, and we can also anticipate required
changes to our products based on new versions of these vendors' platforms. We
believe that these relationships allow us to focus on our core competencies,
simplify the task of designing and developing software and reduce the time it
takes us to make our software compatible with their software.



     Technology relationships. We have formed relationships with vendors of
complementary software products. These relationships consist of non-exclusive
contractual agreements to co-market each other's products and share technical
resources in order to better integrate each other's products. We currently have
such agreements with BroadVision and Vignette, two Internet infrastructure
software providers.



     Reseller relationships. We have entered into contractual reseller
agreements with vendors under which we sell software solutions to them for
resale to their customers. We believe these relationships will extend our sales
presence in new and existing markets. We recently entered into reseller
agreements with Acxiom and Harte-Hanks -- two providers of customer data and
strategic marketing services -- and a reseller agreement with Pivotal
Software -- a vendor of sales force automation and customer support software.
Each of these partners has committed resources to training their employees,
co-marketing programs and have incorporated our products into their customer
relationship management market strategies. We provide sales materials and
training to these resellers on the implementation of our software solutions. We
have only recently entered into these reseller agreements and have not yet
generated any revenues from them.

Microsoft                     Microsoft is the worldwide leader in software for personal
                              computers. Microsoft was seeking a campaign management
                              solution to enhance its internal World Wide Marketing
                              Database. Microsoft selected E.piphany over other suppliers
                              of campaign management solutions because of our ability to
                              provide a full range of enterprise solutions focused on
                              personalizing customer relationships and our ability to make
                              our solutions broadly available to distributed knowledge
                              workers and managers in large corporations.

California State Automobile   CSAA is one of the largest of the American Automobile
Association (CSAA)            Association's nationwide affiliates, serving nearly four
                              million members. Because CSAA has separate computer systems
                              for its membership data and its travel services group
                              transaction records, it had difficulty integrating this data
                              to facilitate its efforts to cross-sell and up-sell
                              products. We offered CSAA a software solution that
                              integrates these disparate systems and allows employees to
                              profile customers and manage marketing campaigns.

                              software for enterprise-wide use. To support its Internet
                              commerce initiatives and evaluate their effect on its
                              traditional sales, marketing and distribution channels,
                              Visio required a software solution to integrate and analyze
                              customer data from multiple enterprise systems. Using our
                              software solution, Visio employees can discern how the
                              company's Internet commerce initiatives are affecting its
                              business as a whole. Visio is also using our software
                              solutions to incorporate customer preferences captured on
                              its Internet commerce site into its product development
                              processes.

SALES, MARKETING AND DISTRIBUTION


     To date, we have marketed our products primarily through our direct sales
force. However, we intend to expand our sales channels through additional
relationships with systems integrators and value-added resellers. In selling our
products, we typically approach both business users and information technology
professionals with an integrated team from our sales and professional services
organizations. Initial sales activities typically include a demonstration of our
product capabilities followed by one or more detailed technical reviews. We also
seek to establish alliances and partnerships with major industry vendors that
will add value to our products and expand distribution opportunities. As of June
30, 1999, our sales and marketing organization consisted of 38 employees.



     We use a variety of marketing programs to build market awareness of our
company, our brand name and our products, as well as to attract potential
customers. These programs include our own market research, product and strategy
updates with industry analysts, public relations activities, direct mail
programs, telemarketing and telesales, seminars, trade shows, reseller programs,
speaking engagements and Web site marketing. Our marketing organization also
produces marketing materials in support of sales to prospective customers that
include brochures, data sheets, white papers, presentations and demonstrations.


INTELLECTUAL PROPERTY AND OTHER PROPRIETARY RIGHTS

     Our future success depends in part on legal protection of our technology.
To protect our technology, we rely on a combination of the following methods,
among others:


     - patent laws



     - copyright laws



     - trademark laws



     - trade secret laws, or



     - employee and third-party nondisclosure agreements and confidentiality
       procedures.


     We have applied for seven patents on our technology in the United States;
we have also received several trademark registrations and applied for additional
trademarks. Our pending patent and trademark applications may not be allowed.
Even if they are allowed, these patents may not provide us a competitive
advantage. Competitors may successfully challenge the validity and scope of our
patents and trademarks.

     Our end-user licenses are designed to prohibit unauthorized use, copying
and disclosure of our software and technology. However, these provisions may be
unenforceable under the laws of some jurisdictions and foreign countries.
Unauthorized third parties may be able to copy some portions of our products or
reverse engineer or obtain and use information and technology that we regard as
proprietary. Third parties could also independently develop competing technology
or design around our technology. If we are unable to successfully detect
infringement and enforce our rights in our technology, we may lose competitive
position in the market. We cannot assure you that our means of protecting its
proprietary rights in the United States or abroad will be adequate or that
competing companies will not independently develop similar technology. In
addition, some of our licensed users may allow additional unauthorized users to
use our software, and if we do not detect such use we could lose potential
license fees.

     From time to time, we may encounter disputes over rights and obligations
concerning intellectual property. We believe that our products do not infringe
the intellectual property rights of third parties. However, we cannot assure you
that we will prevail in all intellectual property disputes. We have not
conducted a search for existing patents and other intellectual property
registrations, and we cannot assure you that our products do not infringe upon
issued patents. In addition, because patent applications in the United States
are not publicly disclosed until the patent is issued, applications may have
been filed which would relate to our products.

     We indemnify some of our customers against claims that our products
infringe upon the intellectual property rights of others. We could incur
substantial costs in defending ourselves and our customers

                                       44
<PAGE>   47

against infringement claims. In the event of a claim of infringement, we or our
customers may be required to obtain one or more licenses from third parties. We
cannot assure you that such licenses could be obtained from third parties at a
reasonable cost, or at all. Defense of any lawsuit or failure to obtain any such
required license would have a material adverse effect on our business.

COMPETITION


     The market for our products is intensely competitive, subject to rapid
change and significantly affected by new product introductions and other market
activities of industry participants. Our integrated software compete against
various vendors' software tools designed to accomplish specific elements of a
complete process, including extracting data, storing and managing data,
analyzing data, or managing marketing campaigns. Our competitors include
companies that sell:



     - data management and data analysis software tools such as Brio Technology,
       Business Objects, Cognos, Informatica and Sagent Technology


     - enterprise application software such as i2 Technologies and Siebel
       Systems, and


     - marketing campaigns management software tools such as Exchange
       Applications and Prime Response.



     In addition, enterprise application software vendors such as Oracle,
PeopleSoft and SAP are beginning to offer software for data analysis, although
they typically tend to support only the analysis of data from their own
operational systems. We may also face competition from vendors of software that
recommend products to customers based on simple logic rules, such as Net
Perceptions and Rightpoint Software, Inc.



     Many of our competitors have longer operating histories, significantly
greater financial, technical, marketing, or other resources, or greater name
recognition than we do. Our competitors may be able to respond more quickly to
new or emerging technologies and changes in customer requirements. Competition
could seriously harm our ability to sell additional software, maintenance
renewals, and services on terms favorable to us. Competitive pressures could
reduce our market share or require us to reduce the price of products and
services, any of which could materially and adversely affect our business,
financial condition and operating results.


     We compete on the basis of certain factors, including:

     - product performance

     - product features

     - user scalability

     - open architecture

     - ease of use

     - product reliability

     - analytic capabilities

     - time to market

     - customer support, and

     - product pricing.

       We believe that we presently compete favorably with respect to each of
       these factors. However, the market for our products is still rapidly
evolving, and we may not be able to compete successfully against current and
potential competitors.

EMPLOYEES

     As of June 30, 1999, we had 115 full-time employees. Of these employees, 36
were engaged in research and development, 38 were engaged in sales and
marketing, 28 were engaged in professional services and 13 were engaged in
finance and administration.

     None of our employees is represented by a labor union or a collective
bargaining agreement. We have not experienced any work stoppages and consider
our relations with our employees to be good.

FACILITIES

     We currently lease approximately 13,500 square feet of office space for our
headquarters in one building, located in Palo Alto, California. We have entered
into a lease of approximately 32,500 square feet of office space in one building
in San Mateo, California. We intend to move our headquarters to the San Mateo
office space beginning in September 1999. We also lease sales offices near
Atlanta, Detroit, Dallas, Los Angeles and Stamford, Connecticut. We believe our
new facilities are adequate for our current needs. We may need to locate
additional space to meet our needs in the future.

LEGAL PROCEEDINGS

     From time to time, we may become involved in litigation relating to claims
arising from our ordinary course of business. We believe that there are no
claims or actions pending or threatened against us, the ultimate disposition of
which would have a material adverse effect on us.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     Prior to establishing the compensation committee, the board of directors as
a whole performed the functions delegated to the compensation committee. No
member of the board of directors or the compensation committee serves as a
member of the board of directors or compensation committee of any entity that
has one or more executive officers serving as a member of our board of directors
or compensation committee.

DIRECTOR COMPENSATION


     Directors do not currently receive any cash compensation from us for their
service as members of the board of directors. Under our 1999 stock plan, outside
directors are granted an option to purchase 25,000 shares of our common stock
upon appointment to our board of directors. In addition, an option to purchase
up to 12,500 shares of common stock is granted to each outside director at the
start of each of the second and third years of his service at the then fair
market value of our common stock at that time. During 1999, the board of
directors granted options to purchase 25,000 shares to each of Robert L. Joss
and Paul M. Hazen at an exercise price of $6.00 per share under our 1997 stock
plan. Future grants will be made under our 1999 stock plan after this offering.
See the section entitled "-- Incentive Stock Plans."

OPTION GRANTS IN LAST FISCAL YEAR


     The following table sets forth information with respect to stock options
granted to each of the named executive officers in the fiscal year ended
December 31, 1998, including the potential realizable value over the ten-year
term of the options, based on assumed rates of stock appreciation of 0%, 5% and
10%, compounded annually. These assumed rates of appreciation comply with the
rules of the Securities and Exchange Commission and do not represent our
estimate of future stock price. Actual gains, if any, on stock option exercises
will be dependent on the future performance of our common stock.



     In the fiscal year ended December 31, 1998, we granted options to purchase
up to an aggregate of 2,620,163 shares to employees, directors and consultants.
All options were granted under our 1997 stock plan at exercise prices at or
above the fair market value of our common stock on the date of grant, as
determined in good faith by the board of directors. All options have a term of
ten years. Optionees may pay the exercise price by cash, check, cancellation of
any outstanding indebtedness of the option holder to us or delivery of
already-owned shares of our common stock. All options listed below are
immediately exercisable upon grant; however, any unvested shares are subject to
repurchase by us at their cost if the optionee's service with E.piphany
terminates. All option shares listed in the table below vest over four years,
with 25% of the option shares vesting one year after the option grant date, and
the remaining option shares vesting ratably each month thereafter.

AGGREGATE OPTION EXERCISES IN LAST FISCAL YEAR AND FISCAL YEAR-END OPTION VALUES

     The following table describes for the named executive officers their option
exercises for the fiscal year ended December 31, 1998, and exercisable and
unexercisable options held by them as of December 31, 1998.


     The "Value of Unexercised In-the-Money Options at December 31, 1998" is
based on a value of $3.92 per share, the deemed fair market value of our common
stock as of December 31, 1998, less the per share exercise price, multiplied by
the number of shares issued upon exercise of the option. All options were
granted under our 1997 stock plan. All options listed below are immediately
exercisable; however, as a condition of exercise, the optionee must enter into a
restricted stock purchase agreement granting us the right to repurchase any
unvested portion of the shares issuable by such exercise at their cost in the
event of the optionee's termination of employment. The shares vest over four
years, with 25% of the shares vesting one year after the grant date and the
remaining shares vesting ratably each month thereafter.

INCENTIVE STOCK PLANS

  1997 STOCK OPTION PLAN


     Our 1997 stock plan provides for the granting to employees of incentive
stock options within the meaning of Section 422 of the Internal Revenue Code of
1986, as amended, and for the granting to employees and consultants of
nonstatutory stock options and stock purchase rights. As of June 30, 1999,
options to purchase an aggregate of 2,791,356 shares of common stock were
outstanding under our 1997 stock plan. Our board of directors has determined
that no further options will be granted under the 1997 stock plan after this
offering. The 1997 stock plan provides that if we merge with or into another
corporation, or sell substantially all of our assets, each outstanding option
must be assumed or substituted for by the successor corporation. If the
successor corporation refuses to assume or substitute for the E.piphany options,
the E.piphany options will terminate as of the closing of the merger or sale of
assets.


  1999 STOCK PLAN


     Our 1999 stock plan was adopted by our board of directors in June 1999 and
approved by the stockholders in July 1999. As of the date of this prospectus, no
options or stock purchase rights have been granted under our 1999 stock plan.
Our 1999 stock plan provides for the grant of incentive stock options to
employees, including officers and employee directors, and for the grant of
nonstatutory stock options and stock purchase rights to employees, directors and
consultants.



     A total of 3,500,000 shares of our common stock has been reserved for
issuance under the 1999 stock plan. In addition, the plan will include:



     - the shares of common stock which have been reserved but not granted under
       our 1997 stock plan as of the effective date of the offering (as of June
       30, 1999, there were 680,621 shares reserved but not yet granted under
       our 1997 stock plan) and



     - any shares returned to our 1997 stock plan as a result of termination of
       options under the 1997 stock plan before the date of our initial public
       offering.


                                       52
<PAGE>   55


     In addition, commencing January 1, 2000, annual increases will be added to
the 1999 stock plan equal to the lesser of: (A) 2,500,000 shares, (B) 4% of all
outstanding shares of our common stock or (C) a lesser amount determined by our
board of directors.



     Unless terminated sooner, our 1999 stock plan will terminate automatically
ten years from the effective date of this offering.


     The administrator of our 1999 stock plan, which is currently our board of
directors, has the power to determine among other things:

     - the terms of the options or stock purchase rights granted, including the
       exercise price of each option or stock purchase right

     - the number of shares subject to each option or stock purchase right

     - the exercisability of each option or stock purchase right, and

     - the form of consideration payable upon the exercise of each option or
       stock purchase right.


     In addition, the administrator has the authority to amend, suspend or
terminate our 1999 stock plan, so long as the action does not affect any shares
of common stock previously issued and sold or any option previously granted
under our 1999 stock plan. During any fiscal year, each optionee may be granted
options to purchase a maximum of 750,000 shares. In addition, in connection with
an optionee's initial employment with us, such optionee may be granted an option
covering an additional 750,000 shares.



     Options and stock purchase rights granted under our 1999 stock plan are
generally not transferable by the optionee, and each option and stock purchase
right is exercisable during the lifetime of the optionee only by the optionee.
Options granted under our 1999 stock plan must generally be exercised within
three months after the end of the optionee's status as an employee, director or
consultant of E.piphany, or within twelve months after such optionee's
termination by death or disability, but not later than the expiration of the
option's term.


     In the case of stock purchase rights, unless the administrator determines
otherwise, the restricted stock purchase agreement grants E.piphany a repurchase
option, exercisable for any unvested stock purchase rights, upon the voluntary
or involuntary termination of the purchaser's employment or consulting
relationship with E.piphany for any reason, including death or disability. The
purchase price for shares repurchased pursuant to the restricted stock purchase
agreement shall be the original price paid by the purchaser and may be paid by
cancellation of any indebtedness of the purchaser to E.piphany. The repurchase
option lapses at a rate determined by the administrator.

     The exercise price of all incentive stock options granted under the 1999
stock plan must be at least equal to the fair market value of the common stock
on the date of grant. The exercise price of nonstatutory stock options and stock
purchase rights granted under the 1999 stock plan is determined by the
administrator, but with respect to nonstatutory stock options intended to
qualify as "performance-based compensation" within the meaning of Section 162(m)
of the Internal Revenue Code, the exercise price must be at least equal to the
fair market value of our common stock on the date of grant. With respect to any
participant who owns stock having more than 10% of the voting power of all
classes of our outstanding capital stock, the exercise price of any incentive
stock option granted must be at least equal to 110% of the fair market value on
the grant date and the term of such incentive stock option must not exceed five
years. The term of all other options granted under the 1999 stock plan may not
exceed ten years.

     The 1999 stock plan provides that if we merge with or into another
corporation, or sell substantially all of our assets, each option and stock
purchase right must be assumed or an equivalent option or stock purchase right
substituted for by the successor corporation. If the outstanding options and
stock purchase rights are not assumed or substituted for by the successor
corporation, the optionees shall become fully vested in and have the right to
exercise such options or stock purchase rights. If an option or stock purchase
right becomes fully vested and exercisable in the event of a merger or sale of
assets, the administrator must notify the optionee that the option or stock
purchase right is fully exercisable for a

                                       53
<PAGE>   56

period of 15 days from the date of the notice, and the option or stock purchase
right will terminate upon the expiration of the 15 day period.

  1999 EMPLOYEE STOCK PURCHASE PLAN


     Our 1999 employee stock purchase plan was adopted by our board of directors
in June 1999, and approved by the stockholders in July 1999. A total of
2,000,000 shares of our common stock has been reserved for issuance under the
1999 purchase plan, plus annual increases equal to the lesser of: (A) 2,000,000
shares, (B) 4% of the outstanding shares on such date or (C) a lesser amount
determined by our board of directors. As of the date of this prospectus, no
shares have been issued under the 1999 purchase plan.


     The 1999 purchase plan, which is intended to qualify under Section 423 of
the Internal Revenue Code, contains consecutive, overlapping, twenty-four month
offering periods. Each offering period includes four six-month purchase periods.
The offering periods generally start on the first trading day on or after May 1
and November 1 of each year, except for the first such offering period which
commences on the first trading day on or after the effective date of this
offering and ends on the last trading day on or before October 31, 2001.

     Employees are eligible to participate if they are customarily employed by
E.piphany or any participating subsidiary for at least 20 hours per week and for
more than five months in any calendar year. However, employees may not be
granted an option to purchase stock under the 1999 purchase plan if they either:

     - immediately after grant, own stock possessing 5% or more of the total
       combined voting power or value of all classes of our capital stock, or

     - hold rights to purchase stock under our employee stock purchase plans
       which accrue at a rate which exceeds $25,000 worth of stock for each
       calendar year.

     The 1999 purchase plan permits participants to purchase our common stock
through payroll deductions of up to 15% of the participant's "compensation."
Compensation is defined as the participant's base straight time gross earnings,
overtime, shift premium and bonuses, but excludes other compensation. The
maximum number of shares a participant may purchase during a single purchase
period is 20,000 shares.

     Amounts deducted and accumulated by the participant are used to purchase
shares of common stock at the end of each purchase period. The price of stock
purchased under the 1999 purchase plan is generally 85% of the lower of the fair
market value of the common stock either:

     - at the beginning of the offering period, or

     - at the end of the purchase period.

     In the event the fair market value at the end of a purchase period is less
than the fair market value at the beginning of the offering period, the
participants will be withdrawn from the current offering period following
exercise and automatically re-enrolled in a new offering period. The new
offering period will use the lower fair market value as of the first date of the
new offering period to determine the purchase price for future purchase periods.
Participants may end their participation at any time during an offering period,
and they will be paid their payroll deductions to date. Participation ends
automatically upon termination of employment with E.piphany.

     Rights granted under the 1999 purchase plan are not transferable by a
participant other than by will, the laws of descent and distribution, or as
otherwise provided under the 1999 purchase plan. The 1999 purchase plan provides
that, if a merge with or into another corporation or a sale of substantially all
of our assets, each outstanding option may be assumed or substituted for by the
successor corporation. If the successor corporation refuses to assume or
substitute for the outstanding options, the offering period then

                                       54
<PAGE>   57

in progress will be shortened and a new exercise date will be set. The new
exercise date will be set prior to the proposed date of the merger or sale of
assets.

     Our board of directors has the authority to amend or terminate the 1999
purchase plan, except that they may not adversely affect any outstanding rights
to purchase stock under the 1999 purchase plan. However, the board of directors
may terminate an offering period on any exercise date if the board determines
that the termination of the 1999 purchase plan is in our best interests and the
best interest of our stockholders. Notwithstanding anything to the contrary, the
board of directors may in its sole discretion amend the 1999 purchase plan to
the extent necessary and desirable to avoid unfavorable financial accounting
consequences by altering the purchase price for any offering period, shortening
any offering period or allocating remaining shares among the participants. The
1999 purchase plan will terminate automatically ten years from the effective
date of this offering unless terminated earlier by our board of directors.

401(K) PLAN


     In January 1999, we adopted a 401(k) plan to provide eligible employees
with a tax preferential savings and investment program. Employees become
eligible to participate in the 401(k) plan on the first day they perform an hour
of service for us. Eligible participants may elect to reduce their current
compensation up to the lesser of 15% of eligible compensation or the statutorily
prescribed annual limit, currently $10,000, and have such reduction contributed
to the 401(k) plan. The 401(k) plan permits, but does not require, us to make
additional matching contributions to the 401(k) plan on behalf of eligible
participants. We have not made any matching contributions to the 401(k) plan to
date. All contributions made by and on behalf of participants are subject to a
maximum contribution limitation currently equal to the lesser of 25% of their
compensation or $30,000 per year. At the direction of each participant, the
trustee of the 401(k) plan invests the assets of the 401(k) plan in selected
investment options. Contributions by participants or by us to the 401(k) plan,
and income earned on plan contributions, are generally not taxable to the
participants until withdrawn, and contributions by us, if any, are generally
deductible by us when made.


CHANGE IN CONTROL, SEVERANCE AND EMPLOYMENT ARRANGEMENTS


     In connection with our hiring of Roger S. Siboni as our President and Chief
Executive Officer in July 1998, we sold 1,600,000 shares of our common stock to
him at a purchase price of $0.40 per share in exchange for a promissory note and
cash. We have a right to repurchase these shares of stock at a price of $0.40
per share. Our right to repurchase Mr. Siboni's shares lapses as to 1/48 of his
total number of shares at the end of each month after May 1, 1998. However, our
right to repurchase Mr. Siboni's shares terminates as to all of his shares upon
a change in control of E.piphany in which Mr. Siboni is not given equivalent
compensation and title in the post change of control entity. See the sections
entitled "Certain Transactions -- Common Stock Sales" and " -- Employee Loans."


     In a merger or a sale of substantially all of our assets, if the options
under our 1997 stock plan are not assumed or substituted for, each outstanding
option will terminate as of the closing of the merger or sale of assets. In a
merger or a sale of substantially all of our assets, if the options outstanding
under our 1999 stock plan are not assumed or substituted, each outstanding
option will vest fully and become immediately exercisable.

LIMITATIONS ON DIRECTORS' LIABILITY AND INDEMNIFICATION

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

     - any breach of their duty of loyalty to the corporation or its
       stockholders

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

     - unlawful payments of dividends or unlawful stock repurchases or
       redemptions, or

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

     This limitation of liability does not apply to liabilities arising under
the federal securities laws and does not affect the availability of equitable
remedies such as injunctive relief or rescission.

     Our certificate of incorporation and bylaws provide that we shall indemnify
our directors and executive officers and may indemnify our other officers and
employees and other agents to the fullest extent permitted by law. We believe
that indemnification under our bylaws covers at least negligence and gross
negligence on the part of indemnified parties. Our bylaws also permit us to
secure insurance on behalf of any officer, director, employee or other agent for
any liability arising out of his or her actions in such capacity, regardless of
whether our bylaws would permit indemnification.

     We have entered into agreements to indemnify our directors and executive
officers, in addition to the indemnification provided for in our bylaws. These
agreements, among other things, provide for indemnification of our directors and
executive officers for expenses, judgments, fines and settlement amounts
incurred by any such person in any action or proceeding arising out of such
person's services as a director or executive officer or at our request. We
believe that these provisions and agreements are necessary to attract and retain
qualified persons as directors and executive officers.

an officer of E.piphany at the time of the purchase.



COMMON STOCK PURCHASES AND SALES



     At the time of E.piphany's foundation, E.piphany entered into stock
purchase agreements with Steven G. Blank and Eliot L. Wegbreit, founders of
E.piphany. On January 24, 1997, Mr. Blank and Dr. Wegbreit each purchased
2,100,000 shares of our common stock under their agreements at a purchase price
of $0.0005 per share for $1,050 each. Mr. Blank was an officer of E.piphany and
Dr. Wegbreit is chairman of our board of directors. We had the right to
repurchase Mr. Blank's and Dr. Wegbreit's shares at their original purchase
price of $0.0005 per share if E.piphany terminated their respective employment
for cause or upon their death or disability. Our repurchase right lapsed as to
1/48 of the total number of shares at the end of each month after November 1,
1996.



     In March 1999, Dr. Wegbreit resigned as Executive Vice President,
Engineering of E.piphany. In accordance with the terms of his stock purchase
agreement, Mr. Wegbreit's remaining shares of common stock are no longer subject
to our repurchase right.



     On August 6, 1999, Steve G. Blank, who was at the time our Executive Vice
President of Marketing, resigned from E.piphany to pursue other interests. In
connection with Mr. Blank's resignation, agreed to sell 125,000 shares of his
common stock will be repurchased for a total purchase price of $62.50. In


                                       57
<PAGE>   60


accordance with the terms of his stock purchase agreement, Mr. Blank's remaining
shares of common stock will no longer be subject to our repurchase right. Mr.
Blank has agreed to continue as a consultant to E.piphany for up to five days
per month, until February 6, 2000. E.piphany will not be required to pay any
consulting fees to Mr. Blank, however, after the earlier of February 6, 2000 or
the termination of the lock-up period which restricts Mr. Blank's sale of his
shares of E.piphany common stock for up to 180 days following this offering.



     In connection with our hiring of Roger S. Siboni, our President and Chief
Executive Officer, on July 7, 1998 we sold an aggregate of 1,600,000 shares of
common stock to Mr. Siboni at a purchase price of $0.40 per share. Mr. Siboni
paid for his shares with a promissory note in the amount of $639,680 and $320 in
cash. The principal amount of the note accrues simple interest at a rate of
5.88% per year.



     On January 16, 1998, in connection with our Series B financing, we sold an
aggregate of 250,000 shares of our common stock to entities affiliated with
Kleiner Perkins Caufield & Byers, a 5% stockholder of E.piphany, at a purchase
price of $0.25 per share.


EMPLOYEE LOANS


     In addition to the loan to purchase stock given to Mr. Siboni, in
connection with his offer of employment as our President and Chief Executive
Officer, Mr. Siboni received a loan of $175,000 for relocation expenses. The
entire amount of the loan was forgiven under the terms of the loan on March 31,
1999. We have also offered to loan to Mr. Siboni up to $250,000 per year for two
years, drawable monthly. Mr. Siboni is currently drawing down this loan at a
rate of $20,833 per month. As of June 30, 1999, the total outstanding principal
amount of this loan is $267,000. This loan bears interest at a rate per annum of
5.6% compounded monthly and is repayable upon Mr. Siboni's first sales of our
stock. Mr. Siboni is also eligible for an annual bonus of up to $125,000, which
is first applied to any outstanding loan balance that Mr. Siboni has with
E.piphany including the loan described above.


INDEMNIFICATION AGREEMENTS

     We have entered into agreements to indemnify our directors and executive
officers, in addition to indemnification provided for in our bylaws. These
agreements, among other things, provide for indemnification of our directors and
executive officers for expenses, judgments, fines and settlement amounts
incurred by any such person in any action or proceeding arising out of such
person's services as a director or executive officer or at our request. We
believe that these provisions and agreements are necessary to attract and retain
qualified persons as directors and executive officers.

     We believe that the shares sold in transactions described above were sold
at fair market value and the terms of the other arrangements described above
were no less favorable than we could have obtained from unaffiliated third
parties.

     In addition to the transactions described above, we have compensation
arrangements with directors and officers which are described under the section
entitled "Management."

                          DESCRIPTION OF CAPITAL STOCK

GENERAL


     Our preferred stock outstanding prior to this offering will automatically
be converted into common stock upon the closing of this offering according to
the terms of our certificate of incorporation. We will file an amended
certificate of incorporation to be effective upon the closing of this offering
that creates a new class of preferred stock. No shares of the new preferred
stock will be outstanding upon completion of this offering. Upon the completion
of this offering, we will be authorized to issue 100,000,000 shares of common
stock, $0.0001 par value, and 5,000,000 shares of undesignated preferred stock,
$0.0001 par value. The following description of our capital stock is subject to
and qualified in its entirety by our amended certificate of incorporation and
bylaws, which are included as exhibits to the registration statement of which
this prospectus forms a part, and by the provisions of applicable Delaware law.


COMMON STOCK


     As of June 30, 1999, there were 9,521,798 shares of common stock
outstanding which were held of record by approximately 76 stockholders and upon
conversion of all outstanding shares of convertible preferred stock, which will
automatically occur upon the closing of this offering according to the terms of
our certificate of incorporation, there will be an aggregate of 21,081,790
shares of common stock outstanding.


     The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding preferred stock, the holders of common stock are
entitled to receive ratably such dividends, if any, as may be declared from time
to time by the board of directors out of funds legally available for that
purpose. See "Dividend Policy." In the event of the liquidation, dissolution or
winding up of E.piphany, the holders of common stock are entitled to share
ratably in all assets remaining after payment of liabilities, subject to prior
distribution rights of preferred stock, if any, then outstanding. The holders of
common stock have no preemptive or conversion rights or other subscription
rights. There are no redemption or sinking fund provisions applicable to the
common stock. Wilson Sonsini Goodrich & Rosati, Professional Corporation,
counsel to E.piphany, is delivering a legal opinion that the shares of common
stock to be issued upon the closing of this offering, when issued and sold in
the manner described in this prospectus and in accordance with the resolutions
adopted by the board of directors, will be fully paid and nonassessable.

PREFERRED STOCK

     The board of directors has the authority, without action by the
stockholders, to designate and issue preferred stock in one or more series and
to designate the rights, preferences and privileges of each series, which may be
greater than the rights of the common stock. It is not possible to state the
actual effect of the issuance of any shares of preferred stock upon the rights
of holders of the common stock until the board of directors determines the
specific rights of the holders of such preferred stock. However, the effects
might include, among other things:

     - restricting dividends on the common stock

     - diluting the voting power of the common stock

     - impairing the liquidation rights of the common stock, or

     - delaying or preventing a change in control of E.piphany without further
       action by the stockholders.

     Upon the closing no shares of preferred stock will be outstanding, and we
have no present plans to issue any shares of preferred stock.

                                       61

WARRANTS


     At June 30, 1999, there were warrants outstanding to purchase 22,124 shares
of Series A preferred stock, up to 75,000 shares of Series B preferred stock,
and up to 31,250 shares of Series C preferred stock which are convertible in the
aggregate into 128,374 shares of common stock.


STOCK PURCHASE OPTION


     At June 30, 1999, there was a stock purchase option outstanding to purchase
up to 351,563 shares of our Series C' Preferred Stock convertible in the
aggregate into 351,563 shares of common stock. This stock purchase option was
granted in connection with our subordinated convertible debt facility. The
holder of this stock purchase option may pay for the shares in cash or by
converting outstanding debt. The stock purchase option will terminate upon
closing of this offering if not exercised prior to the closing.


REGISTRATION RIGHTS


     The holders of 18,747,972 shares of common stock and the holders of
warrants to purchase preferred stock convertible into 75,000 shares of common
stock are entitled to the following rights with respect to registration of such
shares under the Securities Act. These rights are provided under the terms of an
agreement between E.piphany and the holders of registrable securities. Beginning
180 days following the date of this prospectus but not before March 18, 2000, if
holders of at least 50% of the then outstanding registrable securities request
that at least 30% of the then outstanding registrable securities be registered,
we may be required, on up to two occasions, to register their shares for public
resale. We are obligated to register these shares only if the outstanding
registrable securities have an anticipated public offering price of at least
$6,000,000. Also, holders of registrable securities may require on two separate
occasions within any twelve month period that we register their shares for
public resale on Form S-3 or similar short-form registration if the value of the
securities to be registered is at least $2,000,000. Depending on market
conditions, however, we may defer such registration for up to 120 days.
Furthermore, in the event we elect to register any of our shares of common stock
for purposes of effecting any public offering, the holders of the registrable
securities described above and additional holders of warrants to purchase
preferred stock convertible into an additional 22,124 shares of common stock are
entitled to include their shares of common stock in the registration, but we may
reduce the number of shares proposed to be registered in view of market
conditions. We plan to obtain waivers of these registration rights with respect
to this offering. All expenses in connection with any registration, other than
underwriting discounts and commissions, will be borne by us. All registration
rights will terminate five years following the consummation of this offering,
or, with respect to each holder of registrable securities, at such time as the
holder is entitled to sell all of its shares in any three month period under
Rule 144 of the Securities Act.


ANTI-TAKEOVER EFFECTS OF OUR CERTIFICATE AND BYLAWS AND DELAWARE LAW

     Some provisions of Delaware law and our certificate of incorporation and
bylaws could make the following more difficult:

     - acquisition of E.piphany by means of a tender offer

     - acquisition of E.piphany by means of a proxy contest or otherwise, or

     - removal of our incumbent officers and directors.

     These provisions, summarized below, are expected to discourage coercive
takeover practices and inadequate takeover bids. These provisions are also
designed to encourage persons seeking to acquire control of us to first
negotiate with our board. We believe that the benefits of increased protection
of our potential ability to negotiate with the proponent of an unfriendly or
unsolicited proposal to acquire or restructure us outweigh the disadvantages of
discouraging such proposals because negotiation of such proposals could result
in an improvement of their terms.

                                       62
<PAGE>   65

     Election and Removal of Directors. Our board of directors is divided into
three classes. The directors in each class will serve for a three-year term, one
class being elected each year by our stockholders for more information on the
classified board, see the section entitled "Management -- Executive Officers and
Directors." This system of electing and removing directors may tend to
discourage a third party from making a tender offer or otherwise attempting to
obtain control of us because it generally makes it more difficult for
stockholders to replace a majority of the directors.

     Stockholder Meetings. Under our bylaws, only the board of directors, the
chairman of the board and the president may call special meetings of
stockholders.

     Requirements for Advance Notification of Stockholder Nominations and
Proposals. Our bylaws establish advance notice procedures with respect to
stockholder proposals and the nomination of candidates for election as
directors, other than nominations made by or at the direction of the board of
directors or a committee of the board of directors.

     Delaware Anti-Takover Law. We are subject to Section 203 of the Delaware
General Corporation Law, an anti-takeover law. In general, Section 203 prohibits
a publicly held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years following the date
the person became an interested stockholder, unless the "business combination"
or the transaction in which the person became an interested stockholder is
approved in a prescribed manner. Generally, a "business combination" includes a
merger, asset or stock sale, or other transaction resulting in a financial
benefit to the interested stockholder. Generally, an "interested stockholder" is
a person who, together with affiliates and associates, owns or within three
years prior to the determination of interested stockholder status, did own, 15%
or more of a corporation's voting stock. The existence of this provision may
have an anti-takeover effect with respect to transactions not approved in
advance by the board of directors, including discouraging attempts that might
result in a premium over the market price for the shares of common stock held by
stockholders.

     Elimination of Stockholder Action By Written Consent. Our certificate of
incorporation eliminates the right of stockholders to act by written consent
without a meeting.


     Elimination of Cumulative Voting. Our certificate of incorporation and
bylaws do not provide for cumulative voting in the election of directors.
Cumulative voting provides for a minority stockholder to vote a portion or all
of its shares for one or more candidates for seats on the board of directors.
Without cumulative voting, a minority stockholder in favor of a takeover opposed
by the current board of directors generally has a more difficult time getting
persons elected to the board of directors who could influence the board of
directors' decision regarding the takeover.


     Undesignated Preferred Stock. The authorization of undesignated preferred
stock makes it possible for the board of directors to issue preferred stock with
voting or other rights or preferences that could impede the success of any
attempt to change control of E.piphany. These and other provisions may have the
effect of deferring hostile takeovers or delaying changes in control or
management of E.piphany.

     Amendment of Charter Provisions. The amendment of any of the above
provisions would require approval by holders of at least 66 2/3% of the
outstanding common stock.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for the common stock is BankBoston, N.A.

NASDAQ NATIONAL MARKET LISTING


     We have applied for the listing of our shares on The Nasdaq Stock Market's
National Market under the symbol "EPNY."

                        SHARES ELIGIBLE FOR FUTURE SALE

     Sales of substantial amounts of our common stock in the public market after
the offering could adversely affect the market price of our common stock and our
ability to raise equity capital in the future on terms favorable to E.piphany.


     After the offering 25,081,790 shares of our common stock will be
outstanding, assuming that the underwriters do not exercise the over-allotment
option. Of these shares, all of the 4,000,000 shares sold in this offering will
be freely tradable without restriction or further registration under the
Securities Act, unless these shares are purchased by "affiliates" as that term
is defined in Rule 144 under the Securities Act. The remaining shares of common
stock held by existing shareholders are "restricted securities" as that term is
defined in Rule 144 under the Securities Act. Restricted securities may be sold
in the public market only if registered or if they qualify for an exemption from
registration under Rules 144 or 701 under the Securities Act, which are
summarized below.



     The following table shows approximately when the 21,081,790 shares of our
common stock that are not being sold in this offering but which will be
outstanding when this offering is complete will be eligible for sale in the
public market:

     Resale of 15,483,720 of the restricted shares that will become available
for sale in the public market starting 181 days after the effective date will be
limited by volume and other resale restrictions under Rule 144 because the
holders are affiliates of E.piphany.


RULE 144

     In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year is entitled to sell, within any three-month
period, a number of shares that is not more than the greater of:


     - 1% of the number of shares of common stock then outstanding which will
       equal approximately 250,817 shares immediately after this offering; or



     - the average weekly trading volume of our common stock on The Nasdaq Stock
       Market's National Market during the four calendar weeks before a notice
       of the sale on Form 144 is filed.


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

     Under Rule 144(k), a person who has not been one of our affiliates at any
time during the 90 days before a sale, and who has beneficially owned the
restricted shares for at least two years, is entitled to sell the shares without
complying with the manner of sale, public information, volume limitation or
notice provisions of Rule 144.

RULE 701

     In general, under Rule 701 of the Securities Act as currently in effect,
any of our employees, consultants or advisors who purchase shares from us under
a stock option plan or other written agreement can resell those shares 90 days
after the effective date of this offering in reliance on Rule 144, but without
complying with some of the restrictions, including the holding period, contained
in Rule 144. As of

                                       64
<PAGE>   67


June 30, 1999, 2,071,798 shares outstanding had been issued as a result of the
exercise of stock options. Of these shares, 2,004,316 shares will be vested and
exercisable and will be able to be resold after the 90 day period, subject to
the lock-up agreements described below.


LOCK-UP AGREEMENTS


     After this offering approximately 21,081,790 shares of our common stock
held by our directors, executive officers and our existing stockholders are
subject to "lock-up" agreements under which they agree not to sell, contract to
sell, pledge or otherwise dispose of, directly or indirectly, any shares of
common stock or any securities convertible into or exercisable or exchangeable
for shares of common stock or securities convertible into or exchangeable or
exercisable for any shares of common stock, or publicly disclose the intention
to make any such offer, sale, pledge or disposal without the prior consent of
Credit Suisse First Boston Corporation, for a period of 180 days after the date
of this prospectus. Transfers or dispositions can be made sooner with the prior
written consent of Credit Suisse First Boston Corporation.


REGISTRATION RIGHTS


     Upon completion of this offering, the holders of 18,747,972 shares of our
common stock and holders of 97,124 shares of our common stock issuable upon
conversion of warrants, assuming such warrants are converted, will be entitled
to rights to registration of their shares under the Securities Act. After
registration, these shares will become freely tradable without restrictions
under the Securities Act. Any sales of securities by these shareholders could
have a material adverse effect on the trading price of our common stock.


STOCK OPTIONS


     Immediately after this offering we intend to file a registration statement
under the Securities Act covering shares of common stock subject to outstanding
options or reserved for issuance under our stock option plans. Each year as the
number of shares reserved for issuance under our 1999 stock plan and 1999
employee stock purchase plan automatically increases, we will file an amendment
to the registration statement covering the additional shares. As of June 30,
1999, under our 1997 stock plan, options to purchase 2,791,356 shares of common
stock were issued and outstanding and 3,471,977 shares were reserved for future
issuance under our stock plans. When the lock-up agreements described above
expire, options to purchase 2,417,261 shares of common stock will become fully
vested and, when exercised, these shares will be freely tradable, based on the
number of options outstanding as of June 30, 1999. This registration statement
is expected to be filed and become effective as soon as practicable after the
effective date of this offering. Accordingly, shares registered under that
registration statement will, upon the optionee's exercise and subject to vesting
provisions and 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


     Upon consummation of the initial public offering, warrants to purchase up
to 128,374 shares of our common stock will remain outstanding of which warrants
for 75,000 and 22,124 shares will have the registration rights described in the
section entitled "Description of Capital Stock -- Registration Rights."

     Under the terms and subject to the conditions contained in an underwriting
agreement dated                1999, we have agreed to sell to the underwriters
named below, for whom Credit Suisse First Boston Corporation, Hambrecht & Quist
LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated are acting as
representatives, the following respective numbers of shares of common stock:

</TABLE>


     The underwriting agreement provides that the underwriters are obligated to
purchase all of the shares of common stock in the offering if any are purchased,
other than those shares covered by the over-allotment option described below.
The underwriting agreement also provides that if an underwriter defaults, the
purchase commitments of non-defaulting underwriters may be increased or the
offering of common stock may be terminated.


     We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to 600,000 additional shares of common stock at the initial public
offering price less the underwriting discounts and commissions. The option may
be exercised only to cover over-allotments of common stock.


     The underwriters propose to offer the shares of common stock initially at
the public offering price on the cover page of this prospectus and to selling
group members at that price less a concession of $     per share. The
underwriters and selling group members may allow a discount of $     per share
on sales to other broker/dealers. After the initial public offering, the public
offering price and concession and discount to dealers may be changed by the
representatives.

     The following table summarizes the compensation and estimated expenses that
we will pay:

</TABLE>


     The underwriters have informed us that they do not expect discretionary
sales to exceed 5% of the shares of common stock being offered.

     We, our executive officers, directors and our existing stockholders have
agreed not to offer, sell, contract to sell, announce their intention to sell,
pledge or otherwise dispose of, directly or indirectly, or file with the
Commission a registration statement under the Securities Act relating to, any
additional shares of our common stock or securities convertible into or
exchangeable or exercisable for any of our common stock without the prior
written consent of Credit Suisse First Boston Corporation for a period of 180
days after the date of this prospectus.


     The underwriters have reserved for sale, at the initial offering price up
to 280,000 shares of common stock for employees and other persons associated
with us who have expressed an interest in purchasing common stock in the
offering. The number of shares of common stock available for sale to the general
public in the offering will be reduced to the extent these persons purchase the
reserved shares. Any


                                       67
<PAGE>   70

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

     We have agreed to indemnify the underwriters against liabilities under the
Securities Act or to contribute to payments which the underwriters may be
required to make in that respect.

     We have applied to list the shares on The Nasdaq Stock Market's National
Market under the symbol "EPNY."

     Prior to the offering, there has been no public market for our common
stock. The initial public offering price for the common stock will be determined
by negotiation between the representatives and us and does not reflect the
market price of the common stock following the offering. Among the principal
factors considered in determining the initial public offering price will be:

          -  the information in this prospectus and otherwise available to the
             representatives

          -  market conditions for initial public offerings

          -  the history of and prospects for the industry in which we will
             compete

          -  the ability of our management

          -  our prospects for our future earnings

          -  the present state of our development and our current financial
             condition


          -  the recent market prices of, and the demand for, publicly traded
             common stock of generally comparable companies, and



          -  the general condition of the securities markets at the time of this
             offering.



     We can offer no assurances that the initial public offering price will
correspond to the price at which the common stock will trade in the public
market subsequent to the offering or that an active trading market for the
common stock will develop and continue after the offering.


     The representatives may engage in over-allotment, stabilizing transactions,
syndicate covering transactions and penalty bids in accordance with Regulation M
under the Securities Exchange Act:

          -  Over-allotment involves syndicate sales in excess of the offering
             size, which creates a syndicate short position.

          -  Stabilizing transactions permit bids to purchase the underlying
             security so long as the stabilizing bids do not exceed a specified
             maximum.

          -  Syndicate covering transactions involve purchases of the common
             stock in the open market after the distribution has been completed
             in order to cover syndicate short positions.


          -  Penalty bids permit the representatives to reclaim a selling
             concession from a syndicate member when the common stock originally
             sold by the syndicate member is purchased in a syndicate covering
             transaction to cover syndicate short positions. The representatives
             track these purchases through the initial public offering tracking
             system operated by the Depository Trust Company. The
             representatives may, at their discretion, reclaim a selling
             concession from any syndicate member that appears to have permitted
             its customers to purchase shares in the initial public offering and
             then promptly resell all or a portion of those shares to the
             syndicate member that sold them.


     These stabilizing transactions, syndicate covering transactions and penalty
bids may cause the price of the common stock to be higher than it would
otherwise be in the absence of such transactions. These transactions may be
effected on The Nasdaq Stock Market's National Market or otherwise and, if
commenced, may be discontinued at any time.

                          NOTICE TO CANADIAN RESIDENTS

RESALE RESTRICTIONS

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

REPRESENTATIONS OF PURCHASERS

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

RIGHTS OF ACTION (ONTARIO PURCHASERS)

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

ENFORCEMENT OF LEGAL RIGHTS

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

NOTICE TO BRITISH COLUMBIA RESIDENTS

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

TAXATION AND ELIGIBILITY FOR INVESTMENT

     Canadian purchasers of common stock should consult their own legal and tax
advisors with respect to the tax consequences of an investment in the common
stock in their particular circumstances and with respect to the eligibility of
the common stock for investment by the purchaser under relevant Canadian
legislation.

                                 LEGAL MATTERS


     The validity of the shares of common stock offered hereby will be passed
upon for us by Wilson Sonsini Goodrich & Rosati, Professional Corporation, Palo
Alto, California. Some legal matters will be passed upon for the underwriters by
Morrison & Foerster LLP, Palo Alto, California. As of the date of this
prospectus, WS Investments, an investment partnership composed of some current
and former members of and persons associated with Wilson Sonsini Goodrich &
Rosati, Professional Corporation, as well as several individual attorneys of
this firm, beneficially own a total of 78,462 shares of our common stock. Aaron
J. Alter, a member of Wilson Sonsini Goodrich & Rosati, is the Secretary of
E.piphany.


                                    EXPERTS

     The financial statements and schedules included in this prospectus and
elsewhere in the registration statement have been audited by Arthur Andersen
LLP, independent public accountants, as indicated in their reports with respect
thereto, and are included herein in reliance upon the authority of said firm as
experts in giving said reports.

                    CHANGE IN INDEPENDENT PUBLIC ACCOUNTANTS

     In July 1998, KPMG Peat Marwick LLP resigned as E.piphany's independent
public accountants, as KPMG Peat Marwick LLP became an integrator of E.piphany's
products and purchased E.piphany's preferred stock. The former independent
accountants' report on E.piphany's financial statements for the year ended
December 31, 1997 did not contain an adverse opinion, a disclaimer of opinion or
any qualifications or modifications related to uncertainty, limitation of audit
scope or application of accounting principles. The former independent public
accountants' report does not cover any of E.piphany's financial statements in
this registration statement. KPMG Peat Marwick LLP did not issue an audit
opinion on E.piphany's financial statements for any other period. There were no
disagreements with the former public accountants on any matter of accounting
principles or practices, financial statement disclosure or auditing scope or
procedure with respect to E.piphany's financial statements up through the time
of dismissal that, if not resolved to the former accountants' satisfaction,
would have caused them to make reference to the subject matter of the
disagreement in connection with their report. In September 1998, E.piphany
retained Arthur Andersen LLP as its independent public accountants. The decision
to retain Arthur Andersen LLP was approved by resolution of the board of
directors. Prior to retaining Arthur Andersen LLP, E.piphany had not consulted
with Arthur Andersen LLP regarding accounting principles.

San Jose, California


June 19, 1999


                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To E.piphany, Inc.:

     We have audited the accompanying balance sheets of E.piphany, Inc. (a
Delaware corporation) as of December 31, 1998 and 1997, and the related
statements of operations, stockholders' equity and comprehensive loss, and cash
flows for the years then ended. These financial statements are the
responsibility of E.piphany'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 financial position of E.piphany, Inc., as of
December 31, 1998 and 1997, and the results of its operations and its cash flows
for the years then ended in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS
            (INFORMATION AS OF JUNE 30, 1999 AND 1998 IS UNAUDITED)

 1. ORGANIZATION AND OPERATIONS


     E.piphany, Inc. ("E.piphany" or the "Company"), formerly Epiphany Marketing
Software, Inc., was incorporated in Delaware in November 1996, and provides
customer-centric analytic solutions that enable companies to understand the
unique needs of individual customers and personalize interactions, products, and
services. In 1997, E.piphany was in the development stage and was primarily
engaged in obtaining equity financing and performing research and development
activities. Although E.piphany began actively selling its products in 1998 and
no longer considers itself to be in the development stage, it has not operated
profitably to date and there are no assurances that it will operate profitably
in the future.


     E.piphany has incurred net operating losses since inception and, as of June
30, 1999, had an accumulated deficit of $22.8 million. E.piphany is subject to
various risks associated with companies in a comparable stage of development,
including having a limited operating history; competition from substitute
products and larger competitors; dependence on a limited number of customers;
dependence on key individuals; and the ability to obtain adequate financing to
support its growth.

 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

UNAUDITED INTERIM FINANCIAL DATA

     The unaudited interim financial statements as of June 30, 1999 and for the
six months ended June 30, 1999 and 1998 have been prepared on the same basis as
the audited financial statements and, in the opinion of management, reflect all
normal recurring adjustments necessary to present fairly the financial
information set forth therein, in accordance with generally accepted accounting
principles.

USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS

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

STATEMENTS OF CASH FLOWS

     For purposes of the statements of cash flows, E.piphany considers all
highly liquid investments purchased with original maturities of three months or
less to be cash equivalents. Cash equivalents consist of amounts on deposit at a
commercial bank and investments in commercial paper and other securities.

CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS

     E.piphany provides credit to its customers in the normal course of
business, performs ongoing credit evaluations of its customers and maintains
allowances for potential credit losses which, to date, have not been material.

SOFTWARE DEVELOPMENT COSTS

     Software development costs incurred prior to the establishment of
technological feasibility are included in research and development expenses.
E.piphany defines establishment of technological feasibility as the completion
of a working model. Software development costs incurred subsequent to the
establishment of technological feasibility through the period of general market
availability of the products are capitalized, if material, after consideration
of various factors, including net realizable value. To date, software
development costs that are eligible for capitalization have not been material
and have been expensed.

STOCK-BASED COMPENSATION

     The Financial Accounting Standards Board ("FASB") issued Statement of
Financial Accounting Standards ("SFAS") No. 123, "Accounting for Stock-Based
Compensation," in October 1995. This accounting standard permits the use of
either a fair value based method of accounting or the method defined in
Accounting Principles Board Opinion 25 ("APB 25"), "Accounting for Stock Issued
to Employees" to account for stock-based compensation arrangements. Companies
that elect to employ the method proscribed by APB 25 are required to disclose
the pro forma net income (loss) that would have resulted from the use of the
fair value based method. E.piphany has elected to continue to account for its
stock-based compensation arrangements under the provisions of APB 25, and
accordingly, has included in Note 6 the pro forma disclosures required under
SFAS No. 123.

REVENUE RECOGNITION

     E.piphany generates several types of revenue including the following:

     License Fees. E.piphany's standard end user license agreement for
E.piphany's products provides for an initial fee to use the product in
perpetuity up to a maximum number of users. E.piphany also enters into other
license agreement types, which allow for the use of E.piphany's products,
usually restricted by the number of employees, the number of users, or the
license term. Fees from licenses are recognized as revenue upon contract
execution, provided all shipment obligations have been met, fees are fixed or
determinable, and collection is probable. Fees from license agreements which
include the right to receive unspecified future products are recognized over the
term of the arrangement or, if not specified, the estimated economic life of the
product.


     When licenses are sold together with consulting and implementation
services, license fees are recognized upon shipment, provided that (1) the above
criteria have been met, (2) payment of the license fees is not dependent upon
the performance of the consulting services, and (3) the services do not include
significant alterations to the features and functionality of the software. To
date, services have been essential to the functionality of the software products
for substantially all license agreements entered into which included
implementation services. For these arrangements and other arrangements which
don't meet the above criteria, both the product license revenues and services
revenue is recognized in accordance with the provisions of Statement of Position
("SOP") 81-1, "Accounting for Performance of Construction Type and Certain
Production Type Contracts." When reliable estimates are available for the costs
and efforts necessary to complete the implementation services, the Company
accounts for the arrangements under the percentage completion contract method
pursuant to SOP 81-1. When such estimates are not available, the completed
contract method is utilized.

            (INFORMATION AS OF JUNE 30, 1999 AND 1998 IS UNAUDITED)

     E.piphany provides for sales returns based on historical rates of return
which, to date, have not been material.


     Maintenance Agreements. Maintenance agreements generally call for E.piphany
to provide technical support and software updates to customers. Revenue on
technical support and software update rights is recognized ratably over the term
of the maintenance agreement and is included in services revenue in the
accompanying statements of operations.



     Consulting, Implementation and Training Services. E.piphany provides
consulting, implementation and training services to its customers. Revenue from
such services, when not sold in conjunction with product licenses, is generally
recognized as the services are performed.


     As of June 30, 1999, $594,000 of accounts receivable was unbilled due to
services performed in advance of billings.


ADVERTISING COSTS



     The Company expenses all advertising costs as incurred. The Company does
not incur any direct-response advertising costs.


COMPREHENSIVE INCOME (LOSS)


     In June 1997, the FASB issued SFAS No. 130, "Reporting Comprehensive
Income," which E.piphany adopted beginning on January 1, 1998. SFAS No. 130
establishes standards for reporting and display of comprehensive income and its
components in a full set of general purpose financial statements. The objective
of SFAS No. 130 is to report a measure of all changes in equity of an enterprise
that results from transactions and other economic events of the period other
than transactions with shareholders ("comprehensive income"). Comprehensive
income is the total of net income and all other non-owner changes in equity. For
each of the two years ended December 31, 1998, and the six months ended June 30,
1999, E.piphany's comprehensive income was equal to net loss.


COMPUTATION OF BASIC AND DILUTED NET LOSS PER SHARE AND PRO FORMA BASIC AND
DILUTED NET LOSS PER SHARE

     Basic and diluted net loss per common share are presented in conformity
with SFAS No. 128, "Earnings Per Share," 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 initial public
offering must be included in the calculation of basic and diluted net loss per
common share as if such stock had been outstanding for all periods presented. To
date, E.piphany has not had any issuances or grants for nominal consideration.

     In accordance with SFAS No. 128, basic net loss per common share has been
computed using the weighted average number of shares of common stock outstanding
during the period, less shares subject to repurchase. Basic and diluted pro
forma net loss per common share, as presented in the statements of

</TABLE>



     E.piphany has excluded all convertible preferred stock, warrants for
convertible preferred stock, outstanding stock options, and shares subject to
repurchase from the calculation of diluted net loss per common share because all
such securities are antidilutive for all periods presented. The total number of
shares excluded from the calculations of diluted net loss per share were
approximately 8,124,000, 14,952,000, and 18,074,000 for the years ended December
31, 1997 and 1998, and the six months ended June 30, 1999, respectively. See
Notes 5 and 6 for further information on these securities.


SEGMENT REPORTING

     During 1998, E.piphany adopted SFAS No. 131, "Disclosures About Segments of
an Enterprise and Related Information." SFAS No. 131 requires a new basis of
determining reportable business segments (i.e., the management approach). This
approach requires that business segment information used by management to assess
performance and manage company resources be the source for information
disclosure. On this basis, E.piphany is organized and operates as one business
segment, the design, development, and marketing of software solutions.

     During the years ended December 31, 1997 and 1998, and the six months ended
June 30, 1998 and 1999, E.piphany did not generate significant revenues in
foreign countries.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the FASB issued SFAS No. 133, "Accounting for Derivative
Instruments and Hedging Activities," which requires companies to record
derivative financial instruments on the balance sheet as assets or liabilities,
measured at fair value. Gains or losses resulting from changes in the values of
those derivatives would be accounted for depending on the use of the derivative
and whether it qualifies for hedge accounting. The key criterion for hedge
accounting is that the hedging relationship must be highly

            (INFORMATION AS OF JUNE 30, 1999 AND 1998 IS UNAUDITED)

effective in achieving offsetting changes in fair value or cash flows. In June
1999, the FASB issued SFAS No. 137, "Accounting For Derivative Instruments and
Hedging Activities -- Deferral of the Effective Date of FASB Statement No. 133,"
which amends SFAS No. 133 to be effective for all fiscal quarters of all fiscal
years beginning after June 15, 2000 (or January 1, 2001 for E.piphany). This
Statement will not have a material impact on the financial condition or results
of the operations of E.piphany.

     In December 1998, the AICPA issued Statement of Position ("SOP") 98-9,
"Modification of SOP 97-2, Software Revenue Recognition, with Respect to Certain
Transactions." SOP 98-9 amends SOP 97-2 and SOP 98-4 by extending the deferral
of the application of certain provisions of SOP 97-2 amended by SOP 98-4 through
fiscal years beginning on or before March 15, 1999. All other provisions of SOP
98-9 are effective for transactions entered into in fiscal years beginning after
March 15, 1999. E.piphany does not anticipate that this statement will have a
material impact on its statement of operations.

of these arrangements including minimum deposits, liquidity ratios, and
quarterly profitability requirements.


     The subordinated convertible debt facility lender has the option to convert
forty-five percent of the outstanding borrowings under the facility as of June
30, 1999 to shares of E.piphany's Series C' preferred stock at a price of $6.40

the following assumptions: risk-free interest rate of 5.6%; expected life of
0.25 years; and expected volatility of 85%. This amount will be recognized as
additional interest expense over the term of this arrangement with the lender.

 5. PREFERRED STOCK

CONVERTIBLE PREFERRED STOCK

     The rights, preferences, and privileges of the holders of preferred stock
are as follows:


     - Dividends are noncumulative and payable only upon declaration by
       E.piphany's board of directors at a rate of $0.12, $0.24, $0.34, $0.34
       and $0.64 per share per annum for Series A, B, C, C', and D preferred
       stock, respectively.



     - The holders of Series A, B, C, C' and D preferred stock have voting
       rights equal to an equivalent number of shares of common stock into which
       it is convertible.

       any time into one share of common stock at the option of the holder,
       subject to adjustment to protect against dilution. E.piphany can be
       required to convert the preferred stock into common stock at the consent
       of not less than two-thirds of the outstanding Series A, B, C, C' and D
       preferred stockholders, voting together as a single class. Each share of
       preferred stock automatically converts upon the closing of

            (INFORMATION AS OF JUNE 30, 1999 AND 1998 IS UNAUDITED)


       the sale of E.piphany's common stock in a public offering in which the
       gross proceeds exceed $10,000,000 and the offering price equals or
       exceeds $10.00 per share or whenever less than 1,250,000 shares of
       preferred stock remain outstanding.



     - In the event of liquidation, dissolution or winding up of E.piphany, the
       holders of Series A, B, C, C' and D preferred stock are entitled to
       receive $1.13, $2.50, $3.38, $3.38 and $6.40 per share, respectively, as
       well as any declared but unpaid dividends on each share, prior to any
       distribution to the holders of common stock. Any remaining distributable
       assets of E.piphany would be distributed among the holders of Series A,
       B, C, C' and D preferred stock and common stock on a pro-rata basis, up
       to a total distribution of $3.40, $7.50, $10.14, $10.14 and $19.20 per
       Series A, B, C, C' and D preferred stock share, respectively, after which

       stock.



     In September 1998, 6,020 shares of Series C preferred stock were granted to
an outside firm for services rendered to E.piphany. The fair value of the Series

WARRANTS


     In May 1997, E.piphany issued a warrant to purchase 22,124 shares of Series
A preferred stock at $1.13 per share in connection with obtaining a line of
credit. The warrant is exercisable through May 2002. The fair value of the
warrant at the date of issuance was estimated using the Black-Scholes model with
the following assumptions: risk-free interest rate of 6.4%; expected life of 4
years; and expected volatility of 85%. The value was determined to be
immaterial.



     In January 1998, E.piphany issued a warrant to purchase shares of Series B
preferred stock at $2.50 per share in connection with obtaining a line of credit
with a bank. The number of shares is calculated based on $97,500 plus a
percentage of borrowings under the revolving line of credit divided by the share
price. At December 31, 1998, this warrant allowed for the purchase of 75,000
shares. The warrant is exercisable through the earlier of January 9, 2003, or
three years after the initial public offering of E.piphany. The fair value of
the warrant at the date of issuance was estimated using the Black-Scholes model
with the following assumptions: risk-free interest rate of 5.6%; expected life
of 3 years; and expected volatility of 85%. The value was determined to be
immaterial.



     In June 1999, E.piphany issued a warrant to purchase 31,250 shares of
Series C preferred stock at $3.38 per share in connection with obtaining an
equipment lease line. The warrant is exercisable immediately and expires in June
2009. The fair value of the warrant at the date of issuance was determined to be
$141,000 and was estimated using the Black-Scholes model with the following
assumptions: risk-free interest rate of 5.2%; expected life of 3 years; and
expected volatility of 85%. This amount will be recognized as additional
interest expense over the term of this arrangement with the lender.

     In January 1998, E.piphany sold 250,000 shares of common stock to a Series

STOCK-BASED COMPENSATION

     In connection with the grant of certain stock options to employees during
the year ended December 31, 1998, and the six months ended June 30, 1999, the
Company recorded deferred compensation of approximately $5.9 million,
representing the difference between the deemed value of the common stock for
accounting purposes and the option exercise price or stock sale price at the
date of the option grant or stock sale. Such amount is presented as a reduction
of stockholders' equity and amortized over the vesting period of the applicable
options in a manner consistent with Financial Accounting Standards Board
Interpretation No. 28. Approximately $0.7 million and $1.3 million was expensed
during the year ended December 31, 1998, and the six months ended June 30, 1999,
respectively. Compensation expense is decreased in the period of forfeiture for
any accrued but unvested compensation arising from the early termination of an
option holder's services.


     During the years ended December 31, 1997 and 1998, and the six months ended
June 30, 1998 and 1999, E.piphany recorded stock-based compensation of $1,000,
$58,000, $2,000, and $251,000, respectively, related to equity instruments
issued to non-employees. Stock-based compensation related to stock options to
purchase common stock which are issued to non-employees is determined based upon
the fair value at the date of issuance in accordance with the provisions of SFAS
No. 123.


STOCK OPTIONS

     In 1997, E.piphany adopted the 1997 Stock Plan (the "Plan") under which
incentive stock options and nonstatutory stock options may be granted to
employees and consultants of E.piphany. The exercise price for incentive stock
options is at least 100% of the fair market value on the date of grant for
employees owning less than 10% of the voting power of all classes of stock and
at least 110% of the fair market value on the date of grant for employees owning
more than 10% of the voting power of all classes of stock. For nonstatutory
stock options, the exercise price is at least 110% of the fair market value on
the date of grant for employees owning more than 10% of voting power of all
classes of stock and at least 85%

            (INFORMATION AS OF JUNE 30, 1999 AND 1998 IS UNAUDITED)

for employees owning less than 10% of the voting power of all classes of stock.
Options generally expire in 10 years. Options are immediately exercisable, but
shares so purchased vest over periods determined by the board of directors,
generally four years. Upon termination of employment, unvested shares may be
repurchased by E.piphany for the original purchase price.


     As of June 30, 1999, an aggregate of 680,621 shares were available for
future option grants under the Plan.


     E.piphany accounts for the Plan under APB 25 whereby the difference between
the exercise price and the fair value at the date of grant is recognized as
compensation expense. Had compensation expense for stock option plans been
determined consistent with SFAS No. 123, net losses would have increased to the
following pro forma amounts (in thousands, except per share data):

 7. INCOME TAXES

     E.piphany accounts for income taxes pursuant to SFAS No. 109, "Accounting
for Income Taxes." A valuation allowance has been recorded for the total
deferred tax assets of E.piphany as a result of uncertainties regarding the
realization of the assets based on the limited operating history of E.piphany,
the lack of profitability to date, and the uncertainty of future profitability.
The components of net deferred tax assets are as follows (in thousands):

     As of December 31, 1998, E.piphany had net operating loss carryforwards of
approximately $11.7 million for federal and state tax purposes. The federal net
operating loss and other credit carryforwards expire on various dates beginning
on 2012 through 2018. The state net operating loss carryforwards will expire in
2004.

     Under current tax law, net operating loss and credit carryforwards
available to offset future income in any given year may be limited upon the
occurrence of certain events, including significant changes in ownership
interests.

     The provision for income taxes differs from the expected tax benefit amount
computed by applying the statutory federal income rate of 34% to income (loss)
before taxes as follows:

            (INFORMATION AS OF JUNE 30, 1999 AND 1998 IS UNAUDITED)

 8. RELATED PARTY TRANSACTIONS


     In 1998, E.piphany loaned its chief executive officer $175,000 for
relocation expenses. In accordance with the loan agreement, the entire amount of
the loan was forgiven on March 31, 1999. The loan was charged to compensation
expense and is included in general and administrative expense in the
accompanying statement of operations for the year ended December 31, 1998. The
chief executive officer was also offered a loan of $250,000 per year for two
years, drawable monthly. This loan bears interest at 5.6% per annum compounded
monthly and is repayable by the officer's first stock sales. As of June 30,
1999, $267,000 was outstanding on this loan. As the repayment of this amount was
contingent on future stock sales, this amount has been expensed as paid.
Advances under the loan were charged to compensation expense in the period in
which the amounts were loaned to the officer and $104,000 and $163,000 are
included in general and administrative expense in the accompanying statements of
operations for the year ended December 31, 1998 and for the six months ended
June 30, 1999, respectively. This chief executive officer was also given a loan
to purchase 1,600,000 shares of common stock at $0.40 per share. This loan is
due on July 1, 2008 and accrues interest at 5.88% per annum.



 9. 401(K) PLAN



     In January 1999, the Company adopted a 401(k) plan (the "401(k)").
Participation in the 401(k) is available to all employees. Employees are
eligible to participate in the 401(k) at any time beginning with their first day
of employment. Each participant may elect to contribute an amount up to 15% of
his or her annual base salary plus commission and bonus, but not to exceed the
statutory limit as prescribed by the Internal Revenue Code. The Company may make
discretionary contributions to the 401(k). To date, no contributions have been
made by the Company.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents, and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

     Article VII of the Registrant's Restated Certificate of Incorporation
provides for the indemnification of directors to the fullest extent permissible
under Delaware law.

     Article VI of the Registrant's Bylaws provides for the indemnification of
officers, directors and third parties acting on behalf of the Registrant if such
person acted in good faith and in a manner reasonably believed to be in and not
opposed to the best interest of the Registrant, and, with respect to any
criminal action or proceeding, the indemnified party had no reason to believe
his or her conduct was unlawful.

     The Registrant has entered into indemnification agreements with its
directors and executive officers, in addition to indemnification provided for in
the Registrant's Bylaws, and intends to enter into indemnification agreements
with any new directors and executive officers in the future.

     The Underwriting Agreement (Exhibit 1.1 hereto) provides for
indemnification by the Underwriters of the registrant and its executive officers
and directors, and by the registrant of the underwriters for some liabilities,
including liabilities arising under the Securities Act, in connection with
matters specifically provided in writing by the Underwriters for inclusion in
the Registration Statement.

     to the 1997 stock plan option pool.


     Except as indicated above, none of the foregoing transactions involved any
underwriters, underwriting discounts or commissions, or any public offering, and
the Registrant believes that each transaction was exempt from the registration
requirements of the Securities Act by virtue of Section 4(2) thereof, Regulation
D promulgated thereunder or Rule 701 pursuant to compensatory benefit plans and
contracts relating to compensation as provided under such Rule 701. The
recipients in such transactions represented
                                      II-2
<PAGE>   96

their intention to acquire the securities for investment only and not with a
view to or for sale in connection with any distribution thereof, and appropriate
legends were affixed to the share certificates and instruments issued in such
transactions. All recipients had adequate access, through their relationships
with the Registrant, to information about the Registrant.

     Schedules not listed above have been omitted because the information
required to be set forth therein is not applicable or is shown in the financial
statements or notes thereto.

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 by the Registrant for liabilities arising under
the Securities Act may be permitted to directors, officers and controlling
persons of the Registrant pursuant to the provisions referenced in Item 14 of
this Registration Statement 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 a director,
officer or controlling person in connection with the securities being registered
hereunder, 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.

                                   SIGNATURES


     Pursuant to the requirements of the Securities Act of 1933, as amended, the
registrant has duly caused this Amendment No. 1 to the Registration Statement on

CREDIT SUISSE FIRST BOSTON CORPORATION
HAMBRECHT & QUIST LLC
MERRILL LYNCH, PIERCE, FENNER & SMITH INCORPORATED
  As Representatives of the Several Underwriters,
    Eleven Madison Avenue,
      New York, N.Y. 10010-3629



Dear Sirs:


         1.   Introductory. E.piphany, Inc., a Delaware corporation ("Company"),
proposes to issue and sell ________ shares ("Firm Securities") of its Common
Stock, $0.0001 par value, ("Securities") and also proposes to issue and sell to
the Underwriters, at the option of the Underwriters, an aggregate of not more
than ________ additional shares ("Optional Securities") of its Securities as set
forth below. The Firm Securities and the Optional Securities are herein
collectively called the "Offered Securities". As part of the offering
contemplated by this Agreement, Credit Suisse First Boston Corporation (the
"Designated Underwriter") has agreed to reserve out of the Firm Securities
purchased by it under this Agreement, up to ________ shares, for sale to the
Company's directors, officers, employees and other parties associated with the
Company (collectively, "Participants"), as set forth in the Prospectus (as
defined herein) under the heading "Underwriters" (the "Directed Share Program").
The Firm Securities to be sold by the Designated Underwriter pursuant to the
Directed Share Program (the "Directed Shares") will be sold by the Designated
Underwriter pursuant to this Agreement at the public offering price. Any
Directed Shares not orally confirmed for purchase by a Participant by the end of
the business day on which this Agreement is executed will be offered to the
public by the Underwriters as set forth in the Prospectus. The Company hereby
agrees with the several Underwriters named in Schedule A hereto ("Underwriters")
as follows:

         2.   Representations and Warranties of the Company. The Company
represents and warrants to, and agrees with, the several Underwriters that:

              (a) A registration statement (No. 333- ) relating to the Offered
         Securities, including a form of prospectus, has been filed with the
         Securities and Exchange Commission ("Commission") and either (i) has
         been declared effective under the Securities Act of 1933 ("Act") and is
         not






                                       1
<PAGE>   2


         proposed to be amended or (ii) is proposed to be amended by amendment
         or post-effective amendment. If such registration statement ("initial
         registration statement") has been declared effective, either (i) an
         additional registration statement ("additional registration statement")
         relating to the Offered Securities may have been filed with the
         Commission pursuant to Rule 462(b) ("Rule 462(b)") under the Act and,
         if so filed, has become effective upon filing pursuant to such Rule and
         the Offered Securities all have been duly registered under the Act
         pursuant to the initial registration statement and, if applicable, the
         additional registration statement or (ii) such an additional
         registration statement is proposed to be filed with the Commission
         pursuant to Rule 462(b) and will become effective upon filing pursuant
         to such Rule and upon such filing the Offered Securities will all have
         been duly registered under the Act pursuant to the initial registration
         statement and such additional registration statement. If the Company
         does not propose to amend the initial registration statement or if an
         additional registration statement has been filed and the Company does
         not propose to amend it, and if any post-effective amendment to either
         such registration statement has been filed with the Commission prior to
         the execution and delivery of this Agreement, the most recent amendment
         (if any) to each such registration statement has been declared
         effective by the Commission or has become effective upon filing
         pursuant to Rule 462(c) ("Rule 462(c)") under the Act or, in the case
         of the additional registration statement, Rule 462(b). For purposes of
         this Agreement, "Effective Time" with respect to the initial
         registration statement or, if filed prior to the execution and delivery
         of this Agreement, the additional registration statement means (i) if
         the Company has advised the Representatives that it does not propose to
         amend such registration statement, the date and time as of which such
         registration statement, or the most recent post-effective amendment
         thereto (if any) filed prior to the execution and delivery of this
         Agreement, was declared effective by the Commission or has become
         effective upon filing pursuant to Rule 462(c), or (ii) if the Company
         has advised the Representatives that it proposes to file an amendment
         or post-effective amendment to such registration statement, the date
         and time as of which such registration statement, as amended by such
         amendment or post-effective amendment, as the case may be, is declared
         effective by the Commission. If an additional registration statement
         has not been filed prior to the execution and delivery of this
         Agreement but the Company has advised the Representatives that it
         proposes to file one, "Effective Time" with respect to such additional
         registration statement means the date and time as of which such
         registration statement is filed and becomes effective pursuant to Rule
         462(b). "Effective Date" with respect to the initial registration
         statement or the additional registration statement (if any) means the
         date of the Effective Time thereof. The initial registration statement,
         as amended at its Effective Time, including all information contained
         in the additional registration statement (if any) and deemed to be a
         part of the initial registration statement as of the Effective Time of
         the additional registration statement pursuant to the General
         Instructions of the Form on which it is filed and including all
         information (if any) deemed to be a part of the initial registration
         statement as of its Effective Time pursuant to Rule 430A(b) ("Rule
         430A(b)") under the Act, is hereinafter referred to as the "Initial
         Registration Statement". The additional registration statement, as
         amended at its Effective Time, including the contents of the initial
         registration statement incorporated by reference therein and including
         all information (if any) deemed to be a part of the additional
         registration statement as of its Effective Time pursuant to Rule
         430A(b), is hereinafter referred to as the "Additional Registration
         Statement". The Initial Registration Statement and the Additional
         Registration Statement are herein referred to collectively as the
         "Registration Statements" and individually as a "Registration
         Statement". The form of prospectus relating to the Offered Securities,
         as first filed with the Commission pursuant to and in accordance with
         Rule 424(b) ("Rule 424(b)") under the Act or (if no such filing is
         required) as included in a Registration Statement, is hereinafter
         referred to as the "Prospectus". No document has been or will be
         prepared or distributed in reliance on Rule 434 under the Act.

              (b) If the Effective Time of the Initial Registration Statement is
         prior to the execution and delivery of this Agreement: (i) on the
         Effective Date of the Initial Registration Statement, the Initial
         Registration Statement conformed in all respects to the requirements of
         the Act and the rules and regulations of the Commission ("Rules and
         Regulations") and did not include any untrue statement of a material
         fact or omit to state any material fact required to be stated therein
         or necessary to make the statements therein not misleading, (ii) on the
         Effective Date of the Additional Registration Statement (if any), each
         Registration Statement conformed, or will conform, in all respects to
         the requirements of the Act and the Rules and Regulations and did not
         include, or will not include, any untrue statement of a material fact
         and did not omit, or will not omit, to state any material fact required
         to be stated therein or necessary to make the statements therein not
         misleading and (iii) on the date of this Agreement, the Initial
         Registration Statement and, if the Effective Time of the Additional
         Registration Statement is prior to the execution and delivery of this
         Agreement, the Additional Registration Statement each conforms, and at
         the time of filing of the Prospectus pursuant to Rule 424(b) or (if no
         such filing is required) at the Effective Date of the Additional
         Registration Statement in which the Prospectus is included, each
         Registration Statement and the Prospectus will conform, in all respects
         to the requirements of the Act and the Rules and Regulations, and
         neither of such documents includes, or will include, any untrue
         statement of a material fact or omits, or will omit, to state any
         material fact required to be stated therein or necessary to make the
         statements therein not misleading. If the Effective Time of the Initial
         Registration Statement is subsequent to the execution and delivery of
         this Agreement: on the Effective Date of the Initial Registration
         Statement, the Initial Registration Statement and the Prospectus will
         conform in all respects to the requirements of the Act and the Rules
         and Regulations, neither of such documents will include any untrue
         statement of a material fact or will omit to state any material fact
         required to be stated therein or necessary to make the statements
         therein not misleading, and no Additional Registration Statement has
         been or will be filed. The two preceding sentences do not apply to
         statements in or omissions from a Registration Statement or the
         Prospectus based upon written information furnished to the Company by
         any Underwriter through the Representatives specifically for use
         therein, it being understood and agreed that the only such information
         is that described as such in Section 7(b) hereof.

              (c) The Company has been duly incorporated and is an existing
         corporation in good standing under the laws of the State of Delaware,
         with power and authority (corporate and other) to own its properties
         and conduct its business as described in the Prospectus; and the
         Company is duly qualified to do business as a foreign corporation in

         qualification.

              (d) Each subsidiary of the Company has been duly incorporated and
         is an existing corporation in good standing under the laws of the
         jurisdiction of its incorporation, with power and authority (corporate
         and other) to own its properties and conduct its business as described
         in the Prospectus; and each subsidiary of the Company is duly qualified
         to do business as a foreign corporation in good standing in all other
         jurisdictions in which its ownership or lease of property or the
         conduct of its business requires such qualification; all of the issued
         and outstanding capital stock of each subsidiary of the Company has
         been duly authorized and validly issued and is fully paid and
         nonassessable; and the capital stock of each subsidiary owned by the
         Company, directly or through subsidiaries, is owned free from liens,
         encumbrances and defects.

              (e) The Offered Securities and all other outstanding shares of

         would give rise to a valid claim against the Company or any Underwriter
         for a brokerage commission, finder's fee or other like payment in
         connection with this offering.

              (g) There are no contracts, agreements or understandings between
         the Company and any person granting such person the right to require
         the Company to file a registration statement under the Act with respect
         to any securities of the Company owned or to be owned by such person or
         to require the Company to include such securities in the securities
         registered pursuant to a Registration Statement or in any securities
         being registered pursuant to any other registration statement filed by
         the Company under the Act.

              (h) The Offered Securities have been approved for listing on The

         connection with the issuance and sale of the Offered Securities by the
         Company, except such as have been obtained and made under the Act and
         such as may be required under state securities laws.

              (j) The execution, delivery and performance of this Agreement, and
         the issuance and sale of the Offered Securities will not result in a
         breach or violation of any of the terms and provisions of, or
         constitute a default under, any statute, any rule, regulation or order
         of any governmental agency or body or any court, domestic or foreign,
         having jurisdiction over the Company or any subsidiary of the Company
         or any of their properties, or any agreement or instrument to which the
         Company or any such subsidiary is a party or by which the Company or
         any such subsidiary is bound or to which any of the properties of the
         Company or any such subsidiary is subject, or the charter or by-laws of
         the Company or any such subsidiary, and the Company has full power and
         authority to authorize, issue and sell the Offered Securities as
         contemplated by this Agreement.

              (k) This Agreement has been duly authorized, executed and
         delivered by the Company.

              (l) Except as disclosed in the Prospectus, the Company and its
         subsidiaries have good and marketable title to all real properties and
         all other properties and assets owned by them, in each case free from
         liens, encumbrances and defects that would materially affect the value
         thereof or materially interfere with the use made or to be made thereof
         by them; and except as disclosed in the Prospectus, the Company and its
         subsidiaries hold any leased real or personal property under valid and
         enforceable leases with no exceptions that would materially interfere

              (m) The Company and its subsidiaries possess adequate
         certificates, authorities or permits issued by appropriate governmental

         revocation or







                                       4

         modification of any such certificate, authority or permit that, if
         determined adversely to the Company or any of its subsidiaries, would
         individually or in the aggregate have a material adverse effect on the
         condition (financial or other), business, properties or results of
         operations of the Company and its subsidiaries taken as a whole
         ("Material Adverse Effect").

              (n) No labor dispute with the employees of the Company or any
         subsidiary exists or, to the knowledge of the Company, is imminent that
         might have a Material Adverse Effect.

              (o) The Company and its subsidiaries own, possess or can acquire
         on reasonable terms, adequate trademarks, trade names and other rights
         to inventions, know-how, patents, copyrights, confidential information
         and other intellectual property (collectively, "intellectual property
         rights") necessary to conduct the business now operated by them, or
         presently employed by them, and have not received any notice of
         infringement of or conflict with asserted rights of others with respect
         to any intellectual property rights that, if determined adversely to
         the Company or any of its subsidiaries, would individually or in the
         aggregate have a Material Adverse Effect.

              (p) Except as disclosed in the Prospectus, neither the Company nor
         any of its subsidiaries is in violation of any statute, any rule,
         regulation, decision or order of any governmental agency or body or any
         court, domestic or foreign, relating to the use, disposal or release of

         environmental laws, is liable for any off-site disposal or
         contamination pursuant to any environmental laws, or is subject to any
         claim relating to any environmental laws, which violation,
         contamination, liability or claim would individually or in the

         of any pending investigation which might lead to such a claim.

              (q) Except as disclosed in the Prospectus, there are no pending
         actions, suits or proceedings against or affecting the Company, any of
         its subsidiaries or any of their respective properties that, if
         determined adversely to the Company or any of its subsidiaries, would
         individually or in the aggregate have a Material Adverse Effect, or
         would materially and adversely affect the ability of the Company to
         perform its obligations under this Agreement, or which are otherwise
         material in the context of the sale of the Offered Securities; and no
         such actions, suits or proceedings are threatened or, to the Company's
         knowledge, contemplated.

              (r) The financial statements included in each Registration
         Statement and the Prospectus present fairly the financial position of
         the Company and its consolidated subsidiaries as of the dates shown and
         their results of operations and cash flows for the periods shown, and
         such financial statements have been prepared in conformity with the
         generally accepted accounting principles in the United States applied
         on a consistent basis, and the schedules included in each Registration
         Statement present fairly the information required to be stated therein.

              (s) Except as disclosed in the Prospectus, since the date of the
         latest audited financial statements included in the Prospectus there
         has been no material adverse change, nor any development or event
         involving a prospective material adverse change, in the condition
         (financial or other), business, properties or results of operations of
         the Company and its subsidiaries taken as a whole, and, except as
         disclosed in or contemplated by the Prospectus, there has been no
         dividend or distribution of any kind declared, paid or made by the
         Company on any class of its capital stock.

              (t) The Company is not and, after giving effect to the offering
         and sale of the Offered Securities and the application of the proceeds
         thereof as described in the Prospectus, will not be an "investment
         company" as defined in the Investment Company Act of 1940.

              (u) The execution and delivery of the Agreement and Plan of Merger
         dated as of __________, 199__ (the "Merger Agreement") between
         E.piphany, Inc., a California corporation (the "California
         Corporation"), and the Company, effecting the reincorporation of the
         California Corporation under the laws of the State of Delaware, was
         duly authorized by all necessary corporate action on the part of each
         of the California Corporation and the Company. Each of the California
         Corporation and the Company had all corporate power and authority to
         execute and deliver the Merger Agreement, to file the Merger Agreement
         with the Secretary of State of California and the Secretary of the
         State of Delaware and to consummate the reincorporation contemplated by
         the Merger Agreement, and the Merger Agreement at the time of execution
         and filing constituted a valid and binding obligation to each of the
         California Corporation and the Company.

              (v) The Company has notified all holders of its securities,
         including any outstanding options, warrants or debt securities, that
         none of such securities and any Company shares underlying such
         securities may be sold or otherwise transferred or disposed of for a
         period of 180 days after the date of the initial public offering of the
         Offered Securities and has imposed a stop-transfer instruction with the
         Company's transfer agent in order to enforce the foregoing lock-up
         provision.

              (w) All outstanding Securities, and all securities convertible
         into or exercisable or exchangeable for Securities, are subject to
         valid and binding agreements (collectively, "Lock-up Agreements") that
         restrict the holders thereof from selling, making any short sale of,
         granting option for the purchase of, or otherwise transferring or
         disposing of, any of such Securities, or any such securities
         convertible into or exercisable or exchangeable for Securities, for a
         period of 180 days after the date of the Prospectus without the prior
         written consent of Credit Suisse First Boston Corporation ("CSFBC").

              (x) Neither the Company nor any of its affiliates does business
         with the government of Cuba or with any person or affiliate located in
         Cuba within the meaning of Section 517.075, Florida Statutes and the
         Company agrees to comply with such Section if prior to the completion
         of the distribution of the Offered Securities it commences doing such
         business.

              (y) Furthermore, the Company represents and warrants to the
         Underwriters that (i) the Registration Statement, the Prospectus and
         any preliminary prospectus comply, and any further amendments or
         supplements thereto will comply, with any applicable laws or
         regulations of foreign jurisdictions in which the Prospectus or any
         preliminary prospectus, as amended or supplemented, if applicable, are
         distributed in connection with the Directed Share Program, and that
         (ii) no authorization, approval, consent, license, order, registration
         or qualification of or with any government, governmental
         instrumentality or court, other than such as have been obtained, is
         necessary under the securities law and regulations of foreign
         jurisdictions in which the Directed Shares are offered outside the
         United States.

              (z) The Company has not offered, or caused the Underwriters to
         offer, any offered Securities to any person pursuant to the Directed
         Share Program with the specific intent to unlawfully influence (i) a
         customer or supplier of the Company to alter the customer's or
         supplier's level or







                                       6

         type of business with the Company or (ii) a trade journalist or
         publication to write or publish favorable information about the Company
         or its products.

         3.   Purchase, Sale and Delivery of Offered Securities. On the basis of
the representations, warranties and agreements herein contained, but subject to
the terms and conditions herein set forth, the Company agrees to sell to the
Underwriters, and the Underwriters agree, severally and not jointly, to purchase
from the Company, at a purchase price of $______ per share, the respective
numbers of shares of Firm Securities set forth opposite the names of the
Underwriters in Schedule A hereto.

         The Company will deliver the Firm Securities to the Representatives for
the accounts of the Underwriters, against payment of the purchase price in
Federal (same day) funds by official bank check or checks or wire transfer to an
account at a bank acceptable to CSFBC drawn to the order of the Company at the
office of Wilson, Sonsini, Goodrich & Rosati, Professional Corporation, at 10:00
A.M., New York time, on ______________, or at such other time not later than
seven full business days thereafter as CSFBC and the Company determine, such
time being herein referred to as the "First Closing Date". For purposes of Rule
15c6-1 under the Securities Exchange Act of 1934, the First Closing Date (if
later than the otherwise applicable settlement date) shall be the settlement
date for payment of funds and delivery of securities for all the Offered
Securities sold pursuant to the offering. The certificates for the Firm
Securities so to be delivered will be in definitive form, in such denominations
and registered in such names as CSFBC requests and will be made available for
checking and packaging at the office of Wilson, Sonsini, Goodrich & Rosati,
Professional Corporation at least 24 hours prior to the First Closing Date.

         In addition, upon written notice from CSFBC given to the Company from
time to time not more than 30 days subsequent to the date of the Prospectus, the
Underwriters may purchase all or less than all of the Optional Securities at the
purchase price per Security to be paid for the Firm Securities. The Company
agrees to sell to the Underwriters the number of shares of Optional Securities
specified in such notice and the Underwriters agree, severally and not jointly,
to purchase such Optional Securities. Such Optional Securities shall be
purchased for the account of each Underwriter in the same proportion as the
number of shares of Firm Securities set forth opposite such Underwriter's name
bears to the total number of shares of Firm Securities (subject to adjustment by
CSFBC to eliminate fractions) and may be purchased by the Underwriters only for
the purpose of covering over-allotments made in connection with the sale of the
Firm Securities. No Optional Securities shall be sold or delivered unless the
Firm Securities previously have been, or simultaneously are, sold and delivered.
The right to purchase the Optional Securities or any portion thereof may be
exercised from time to time and to the extent not previously exercised may be
surrendered and terminated at any time upon notice by CSFBC to the Company.

         Each time for the delivery of and payment for the Optional Securities,
being herein referred to as an "Optional Closing Date", which may be the First
Closing Date (the First Closing Date and each Optional Closing Date, if any,
being sometimes referred to as a "Closing Date"), shall be determined by CSFBC
but shall be not later than five full business days after written notice of
election to purchase Optional Securities is given. The Company will deliver the
Optional Securities being purchased on each Optional Closing Date to the
Representatives for the accounts of the several Underwriters, against payment of
the purchase price therefor in Federal (same day) funds by official bank check
or checks or wire transfer to an account at a bank acceptable to CSFBC drawn to
the order of the Company, at the office of Wilson, Sonsini, Goodrich & Rosati,
Professional Corporation. The certificates for the Optional Securities being
purchased on each Optional Closing Date will be in definitive form, in such
denominations and registered in such names as CSFBC requests upon reasonable
notice prior to such Optional Closing Date and will be made available for
checking and packaging at the office of Wilson, Sonsini, Goodrich & Rosati,
Professional Corporation at a reasonable time in advance of such Optional
Closing Date.

         4.   Offering by Underwriters. It is understood that the several
Underwriters propose to offer the Offered Securities for sale to the public as
set forth in the Prospectus.

         5.   Certain Agreements of the Company. The Company agrees with the
several Underwriters that:

              (a) If the Effective Time of the Initial Registration Statement is
         prior to the execution and delivery of this Agreement, the Company will
         file the Prospectus with the Commission pursuant to and in accordance
         with subparagraph (1) (or, if applicable and if consented to by CSFBC,
         subparagraph (4)) of Rule 424(b) not later than the earlier of (A) the
         second business day following the execution and delivery of this
         Agreement or (B) the fifteenth business day after the Effective Date of
         the Initial Registration Statement.

              The Company will advise CSFBC promptly of any such filing pursuant
         to Rule 424(b). If the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement and
         an additional registration statement is necessary to register a portion
         of the Offered Securities under the Act but the Effective Time thereof
         has not occurred as of such execution and delivery, the Company will
         file the additional registration statement or, if filed, will file a
         post-effective amendment thereto with the Commission pursuant to and in
         accordance with Rule 462(b) on or prior to 10:00 P.M., New York time,
         on the date of this Agreement or, if earlier, on or prior to the time
         the Prospectus is printed and distributed to any Underwriter, or will
         make such filing at such later date as shall have been consented to by
         CSFBC.

              (b) The Company will advise CSFBC promptly of any proposal to
         amend or supplement the initial or any additional registration
         statement as filed or the related prospectus or the Initial
         Registration Statement, the Additional Registration Statement (if any)
         or the Prospectus and will not effect such amendment or supplementation
         without CSFBC's consent; and the Company will also advise CSFBC
         promptly of the effectiveness of each Registration Statement (if its
         Effective Time is subsequent to the execution and delivery of this
         Agreement) and of any amendment or supplementation of a Registration
         Statement or the Prospectus and of the institution by the Commission of
         any stop order proceedings in respect of a Registration Statement and
         will use its best efforts to prevent the issuance of any such stop
         order and to obtain as soon as possible its lifting, if issued.

              (c) If, at any time when a prospectus relating to the Offered
         Securities is required to be delivered under the Act in connection with
         sales by any Underwriter or dealer, any event occurs as a result of
         which the Prospectus as then amended or supplemented would include an
         untrue statement of a material fact or omit to state any material fact
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, or if it is
         necessary at any time to amend the Prospectus to comply with the Act,
         the Company will promptly notify CSFBC of such event and will promptly
         prepare and file with the Commission, at its own expense, an amendment
         or supplement which will correct such statement or omission or an
         amendment which will effect such compliance. Neither CSFBC's consent
         to, nor the Underwriters' delivery of, any such amendment or supplement
         shall constitute a waiver of any of the conditions set forth in Section
         6.

              (d) As soon as practicable, but not later than the Availability
         Date (as defined below), the Company will make generally available to
         its securityholders an earnings statement covering a period of at least
         12 months beginning after the Effective Date of the Initial
         Registration







                                       8
<PAGE>   9

         Statement (or, if later, the Effective Date of the Additional
         Registration Statement) which will satisfy the provisions of Section
         11(a) of the Act. For the purpose of the preceding sentence,
         "Availability Date" means the 45th day after the end of the fourth
         fiscal quarter following the fiscal quarter that includes such
         Effective Date, except that, if such fourth fiscal quarter is the last
         quarter of the Company's fiscal year, "Availability Date" means the
         90th day after the end of such fourth fiscal quarter.

              (e) The Company will furnish to the Representatives copies of each
         Registration Statement (four of which will be signed and will include
         all exhibits), each related preliminary prospectus, and, so long as a
         prospectus relating to the Offered Securities is required to be
         delivered under the Act in connection with sales by any Underwriter or
         dealer, the Prospectus and all amendments and supplements to such
         documents, in each case in such quantities as CSFBC requests. The
         Prospectus shall be so furnished on or prior to 3:00 P.M., New York
         time, on the business day following the later of the execution and
         delivery of this Agreement or the Effective Time of the Initial
         Registration Statement. All other documents shall be so furnished as
         soon as available. The Company will pay the expenses of printing and
         distributing to the Underwriters all such documents.

              (f) The Company will arrange for the qualification of the Offered
         Securities for sale under the laws of such jurisdictions as CSFBC
         designates and will continue such qualifications in effect so long as
         required for the distribution.

              (g) During the period of five years hereafter, the Company will
         furnish to the Representatives and, upon request, to each of the other
         Underwriters, as soon as practicable after the end of each fiscal year,
         a copy of its annual report to stockholders for such year; and the
         Company will furnish to the Representatives (i) as soon as available, a
         copy of each report and any definitive proxy statement of the Company
         filed with the Commission under the Securities Exchange Act of 1934 or
         mailed to stockholders, and (ii) from time to time, such other
         information concerning the Company as CSFBC may reasonably request.

              (h) The Company will pay all expenses incident to the performance
         of its obligations under this Agreement, for any filing fees and other
         expenses (including fees and disbursements of counsel) incurred in
         connection with qualification of the Offered Securities for sale under
         the laws of such jurisdictions as CSFBC designates and the printing of
         memoranda relating thereto, for the filing fee incident to, and the
         reasonable fees and disbursements of counsel to the Underwriters in
         connection with, the review by the National Association of Securities
         Dealers, Inc. of the Offered Securities, for any travel expenses of the
         Company's officers and employees and any other expenses of the Company
         in connection with attending or hosting meetings with prospective
         purchasers of the Offered Securities and for expenses incurred in
         distributing preliminary prospectuses and the Prospectus (including any
         amendments and supplements thereto) to the Underwriters.

              (i) For a period of 180 days after the date of the initial public
         offering of the Offered Securities, the Company will not offer, sell,
         contract to sell, pledge or otherwise dispose of, directly or
         indirectly, or file with the Commission a registration statement under
         the Act relating to, any additional shares of its Securities or
         securities convertible into or exchangeable or exercisable for any
         shares of its Securities, or publicly disclose the intention to make
         any such offer, sale, pledge, disposition or filing, without the prior
         written consent of CSFBC, except issuances of Securities pursuant to
         the conversion or exchange of convertible or exchangeable







                                       9
<PAGE>   10

         securities or the exercise of warrants or options, in each case
         outstanding on the date hereof, grants of employee stock options or
         sales of shares pursuant to the terms of a stock option or employee
         stock purchase plan in effect on the date hereof, and issuances of
         Securities pursuant to the exercise of such options.

              (j) The Company will (i) enforce the terms of each Lock-up
         Agreement, and (ii) to the extent it has not already done so, issue
         stop-transfer instructions to the transfer agent for the Securities
         with respect to any transaction or contemplated transaction that would
         constitute a breach of or default under the applicable Lock-up
         Agreement. In addition, except with the prior written consent of CSFBC,
         the Company agrees (i) not to amend or terminate, or waive any right
         under, any Lock-up Agreement, or take any other action that would
         directly or indirectly have the same effect as an amendment or
         termination, or waiver of any right under any Lock-up Agreement, that
         would permit any holder of Securities, or any securities convertible
         into, or exercisable or exchangeable for Securities, to make any short
         sale of, grant any option for the purpose of, or otherwise transfer or
         dispose of, any such Securities or other securities, prior to the
         expiration of the 180 days after the date of the Prospectus and (ii)
         not to consent to any sale, short sale, grant of an option for the
         purchase of, or other disposition or transfer of shares of Securities
         or securities convertible into or exercisable or exchangeable for
         Securities, subject to a Lock-up Agreement.

              (k) In connection with the Directed Share Program, the Company
         will ensure that the Directed Shares will be restricted to the extent
         required by the National Association of Securities Dealers, Inc. (the
         "NASD") or the NASD rules from sale, transfer, assignment, pledge or
         hypothecation for a period of three months following the date of the
         effectiveness of the Registration Statement. The Designated Underwriter
         will notify the Company as to which Participants will need to be so
         restricted. The Company will direct the transfer agent to place stop
         transfer restrictions upon such securities for such period of time.

                  examined by them and included in the Registration Statements
                  comply as to form in all material respects with the applicable

                  attention that caused them to believe that:

                                    (A) the unaudited financial statements
                           included in the Registration Statements do not comply

                           unaudited financial statements for them to be in
                           conformity with generally accepted accounting
                           principles;

                                    (B) at the date of the latest available
                           balance sheet read by such accountants, or at a
                           subsequent specified date not more than three
                           business days prior to the date of such letter, there
                           was any change in the capital stock or any increase
                           in short-term indebtedness or long-term debt of the
                           Company and its consolidated subsidiaries or, at the
                           date of the latest available balance sheet read by
                           such accountants, there was any decrease in
                           consolidated net current assets or net assets or any
                           increase in stockholders' deficit, as compared with
                           amounts shown on the latest balance sheet included in

                                    (C) for the period from the closing date of
                           the latest income statement included in the
                           Prospectus to the closing date of the latest
                           available income statement read by such accountants
                           there were any decreases, as compared with the
                           corresponding period of the previous year and with
                           the period of corresponding length ended the date of

                           income, or in the total or per share amounts of
                           consolidated net loss.

                  except in all cases set forth in clauses (B) and (C) above for
                  changes, increases or decreases which the Prospectus discloses
                  have occurred or may occur or which are described in such
                  letter; and

                  (iv) they have compared specified dollar amounts (or

                  (in each case to the extent that such dollar amounts,
                  percentages and other financial information are derived from
                  the general accounting records of the Company and its
                  subsidiaries subject to the internal controls of the Company's
                  accounting system or are derived directly from such records by
                  analysis or computation) with the results obtained from
                  inquiries, a reading of such general accounting records and
                  other procedures specified in such letter and have found such
                  dollar amounts, percentages and other financial information to
                  be in agreement with such results, except as otherwise
                  specified in such letter.

         For purposes of this subsection, (i) if the Effective Time of the
         Initial Registration Statement is subsequent to the execution and
         delivery of this Agreement, "Registration Statements" shall mean the
         initial registration statement as proposed to be amended by the
         amendment or post-effective amendment to be filed shortly prior to its
         Effective Time, (ii) if the Effective Time of the Initial Registration
         Statement is prior to the execution and delivery of this Agreement but
         the Effective Time of the Additional Registration is subsequent to such
         execution and delivery, "Registration Statements" shall mean the
         Initial Registration Statement and the additional registration
         statement as proposed to be filed or as proposed to be amended by the
         post-effective amendment to be filed shortly prior to its Effective
         Time, and (iii) "Prospectus" shall mean the prospectus included in the
         Registration Statements.

         The Company shall have received from Arthur Andersen LLP (and furnished

         of Operations of the Company for the fiscal year ending December 31,

         Analysis of Financial Condition and Results of Operations of the
         Company for the six-month period ending June 30, 1999 and the

         Accountants, and such examination report shall be included in the
         Registration Statement.

                  (b) If the Effective Time of the Initial Registration
         Statement is not prior to the execution and delivery of this Agreement,
         such Effective Time shall have occurred not later than 10:00 P.M., New
         York time, on the date of this Agreement or such later date as shall
         have been consented to by CSFBC. If the Effective Time of the
         Additional Registration Statement (if any) is not prior to the
         execution and delivery of this Agreement, such Effective Time shall

         this Agreement or, if earlier, the time the Prospectus is printed and
         distributed to any Underwriter, or shall have occurred at such later
         date as shall have been consented to by CSFBC. If the Effective Time of
         the Initial Registration Statement is prior to the execution and
         delivery of this Agreement, the Prospectus shall have been filed with
         the Commission in accordance with the Rules and Regulations and Section
         5(a) of this Agreement. Prior to such Closing Date, no stop order
         suspending the effectiveness of a Registration Statement shall have
         been issued and no proceedings for that purpose shall have been
         instituted or, to the knowledge of the Company or the Representatives,
         shall be contemplated by the Commission.

                  (c) Subsequent to the execution and delivery of this
         Agreement, there shall not have occurred (i) any change, or any
         development or event involving a prospective change, in the condition
         (financial or other), business, properties or results of operations of
         the Company and its subsidiaries taken as one enterprise which, in the
         judgment of a majority in interest of the

         Underwriters including the Representatives, is material and adverse and
         makes it impractical or inadvisable to proceed with completion of the
         public offering or the sale of and payment for the Offered Securities;
         (ii) any downgrading in the rating of any debt securities of the
         Company by any "nationally recognized statistical rating organization"
         (as defined for purposes of Rule 436(g) under the Act), or any public
         announcement that any such organization has under surveillance or
         review its rating of any debt securities of the Company (other than an
         announcement with positive implications of a possible upgrading, and no
         implication of a possible downgrading, of such rating); (iii) any
         material suspension or material limitation of trading in securities
         generally on the New York Stock Exchange or any setting of minimum
         prices for trading on such exchange, or any suspension of trading of
         any securities of the Company on any exchange or in the
         over-the-counter market; (iv) any banking moratorium declared by U.S.
         Federal or New York authorities; or (v) any outbreak or escalation of
         major hostilities in which the United States is involved, any
         declaration of war by Congress or any other substantial national or
         international calamity or emergency if, in the judgment of a majority
         in interest of the Underwriters including the Representatives, the
         effect of any such outbreak, escalation, declaration, calamity or
         emergency makes it impractical or inadvisable to proceed with
         completion of the public offering or the sale of and payment for the
         Offered Securities.

                  (d) The Representatives shall have received an opinion, dated

                           (vii) The execution, delivery and performance of this
                  Agreement and the issuance and sale of the Offered Securities

                  and provisions of, or constitute a default under, any statute,
                  any rule, regulation or order of any governmental agency or
                  body or any court having jurisdiction over the Company or any

                  subsidiary is a party or by which the Company or any such
                  subsidiary is bound or to which any of the properties of the

                  specified in such opinion on the date specified therein or was
                  included in the Initial Registration Statement or the
                  Additional Registration Statement (as the case may be), and,
                  to the best of the knowledge of such counsel, no stop order
                  suspending the effectiveness of a Registration Statement or

                  purpose have been instituted or are pending or contemplated
                  under the Act, and each Registration Statement and the
                  Prospectus, and each amendment or supplement thereto, as of
                  their respective effective or issue dates, complied as to form
                  in all material respects with the requirements of the Act and
                  the Rules and Regulations; such counsel have no reason to
                  believe that any part of a Registration Statement or any
                  amendment thereto, as of its effective date or as of such
                  Closing Date, contained any untrue statement of a material
                  fact or omitted to state any material fact required to be
                  stated therein or necessary to make the statements therein not
                  misleading or that the Prospectus or any amendment or
                  supplement thereto, as of its issue date or as of such Closing
                  Date, contained any untrue statement of a material fact or
                  omitted to state any material fact necessary in order to make
                  the statements therein, in the light of the circumstances
                  under which they were made, not misleading; the descriptions
                  in the Registration Statements and Prospectus of statutes,
                  legal and governmental proceedings and contracts and other
                  documents are accurate and fairly

                  to be described in a Registration Statement or the Prospectus
                  which are not described as required or of any contracts or
                  documents of a character required to be described in a
                  Registration Statement or the Prospectus or to be filed as
                  exhibits to a Registration Statement which are not described
                  and filed as required; it being understood that such counsel
                  need express no opinion as to the financial statements or
                  other financial data contained in the Registration Statements
                  or the Prospectus;

                           (ix) This Agreement has been duly authorized,
                  executed and delivered by the Company;

                           (x) The statements set forth under the heading
                  "Description of Capital Stock" in the Prospectus, insofar as
                  such statements purport to summarize certain provisions of the
                  capital stock of the Company, provide a fair summary of such
                  provisions;

                           (xi) The statements set forth under the heading
                  "Business--Intellectual Property and Other Proprietary Rights"
                  insofar as such statements constitute a summary of legal
                  matters, documents or proceedings referred to therein, provide
                  a fair summary of such legal matters, documents and
                  proceedings.

                           (xii) The execution and delivery of the Merger
                  Agreement, effecting the reincorporation of the California
                  Corporation under the laws of the State of Delaware, was duly
                  authorized by all necessary corporate action on the part of
                  each of the California Corporation and the Company.

                  (e) The Representatives shall have received from Morrison &
         Foerster LLP, counsel for the Underwriters, such opinion or opinions,
         dated such Closing Date, with respect to the incorporation of the
         Company, the validity of the Offered Securities delivered on such
         Closing Date, the Registration Statements, the Prospectus and other
         related matters as the Representatives may require, and the Company
         shall have furnished to such counsel such documents as they request for
         the purpose of enabling them to pass upon such matters.

                  (f) The Representatives shall have received a certificate,
         dated such Closing Date, of the President or any Vice President and a
         principal financial or accounting officer of the Company in which such
         officers, to the best of their knowledge after reasonable
         investigation, shall state that: the representations and warranties of
         the Company in this Agreement are true and correct; the Company has
         complied with all agreements and satisfied all conditions on its part
         to be performed or satisfied hereunder at or prior to such Closing
         Date; no stop order suspending the effectiveness of any Registration
         Statement has been issued and no proceedings for that purpose have been
         instituted or are contemplated by the Commission; the Additional
         Registration Statement (if any) satisfying the requirements of
         subparagraphs (1) and (3) of Rule 462(b) was filed pursuant to Rule
         462(b), including payment of the applicable filing fee in accordance
         with Rule 111(a) or (b) under the Act, prior to the time the Prospectus
         was printed and distributed to any Underwriter; and, subsequent to the
         date of the most recent financial statements in the Prospectus, there
         has been no material adverse change, nor any development or event
         involving a prospective material adverse change, in the condition
         (financial or other), business, properties or results of operations of
         the Company and its subsidiaries taken as a whole except as set forth
         in or contemplated by the Prospectus or as described in such
         certificate.

              (g) The Representatives shall have received a letter, dated such
         Closing Date, of _____________________which meets the requirements of
         subsection (a) of this Section, except that the specified date referred
         to in such subsection will be a date not more than three days prior to
         such Closing Date for the purposes of this subsection.

The Company will furnish the Representatives with such conformed copies of such
opinions, certificates, letters and documents as the Representatives reasonably
request. CSFBC may in its sole discretion waive on behalf of the Underwriters
compliance with any conditions to the obligations of the Underwriters hereunder,
whether in respect of an Optional Closing Date or otherwise.

         7.   Indemnification and Contribution. (a) The Company will indemnify
and hold harmless each Underwriter, its partners, directors and officers and
each person, if any, who controls such Underwriter within the meaning of Section
15 of the Act, against any losses, claims, damages or liabilities, joint or
several, to which such Underwriter may become subject, under the Act or
otherwise, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in any Registration Statement,
the Prospectus, or any amendment or supplement thereto, or any related
preliminary prospectus, or arise out of or are based upon the omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse
each Underwriter for any legal or other expenses reasonably incurred by such
Underwriter in connection with investigating or defending any such loss, claim,
damage, liability or action as such expenses are incurred; provided, however,
that the Company will not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement in or omission or alleged omission from
any of such documents in reliance upon and in conformity with written
information furnished to the Company by any Underwriter through the
Representatives specifically for use therein, it being understood and agreed
that the only such information furnished by any Underwriter consists of the
information described as such in subsection (b) below.

          The Company agrees to indemnify and hold harmless the Designated
Underwriter and each person, if any, who controls the Designated Underwriter
within the meaning of either Section 15 of the Securities Act or Section 20 of
the Exchange Act (the "DESIGNATED ENTITIES"), from and against any and all
losses, claims, damages and liabilities (including, without limitation, any
legal or other expenses reasonably incurred in connection with defending or
investigating any such action or claim) (i) caused by any untrue statement or
alleged untrue statement of a material fact contained in any material prepared
by or with the consent of the Company for distribution to Participants in
connection with the Directed Share Program or caused by any omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading; (ii) caused by the
failure of any Participant to pay for and accept delivery of Directed Shares
that the Participant agreed to purchase; or (iii) related to, arising out of, or
in connection with the Directed Share Program, other than losses, claims,
damages or liabilities (or expenses relating thereto) that are finally
judicially determined to have resulted from the bad faith or gross negligence of
the Designated Entities.

         (b) Each Underwriter will severally and not jointly indemnify and hold
harmless the Company, its directors and officers and each person, if any, who
controls the Company within the meaning of Section 15 of the Act, against any
losses, claims, damages or liabilities to which the Company may become subject,
under the Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement or alleged untrue statement of any material fact contained in
any Registration Statement, the Prospectus, or any amendment or supplement
thereto, or any







                                       16
<PAGE>   17

related preliminary prospectus, or arise out of or are based upon the omission
or the alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein not misleading, in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was made in reliance upon and
in conformity with written information furnished to the Company by such
Underwriter through the Representatives specifically for use therein, and will
reimburse any legal or other expenses reasonably incurred by the Company in
connection with investigating or defending any such loss, claim, damage,
liability or action as such expenses are incurred, it being understood and
agreed that the only such information furnished by any Underwriter consists of
(i) the following information in the Prospectus furnished on behalf of each
Underwriter: the concession and reallowance figures appearing in the [fourth]
paragraph under the caption "Underwriting" and the information contained in the
[sixth and twelfth] paragraphs under the caption "Underwriting."

         (c) Promptly after receipt by an indemnified party under this Section
of notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against the indemnifying party under
subsection (a) or (b) above, notify the indemnifying party of the commencement
thereof; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under subsection (a) or (b) above. In case any such action is brought against
any indemnified party and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein and, to
the extent that it may wish, jointly with any other indemnifying party similarly
notified, to assume the defense thereof, with counsel satisfactory to such
indemnified party (who shall not, except with the consent of the indemnified
party, be counsel to the indemnifying party), and after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party will not be liable to such indemnified
party under this Section for any legal or other expenses subsequently incurred
by such indemnified party in connection with the defense thereof other than
reasonable costs of investigation. No indemnifying party shall, without the
prior written consent of the indemnified party, effect any settlement of any
pending or threatened action in respect of which any indemnified party is or
could have been a party and indemnity could have been sought hereunder by such
indemnified party unless such settlement (i) includes an unconditional release
of such indemnified party from all liability on any claims that are the subject
matter of such action and (ii) does not include a statement as to, or an
admission of, fault, culpability or a failure to act by or on behalf of an
indemnified party.

         (d) If the indemnification provided for in this Section is unavailable
or insufficient to hold harmless an indemnified party under subsection (a) or
(b) above, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in subsection (a) or (b) above (i) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and the Underwriters on the other from the offering of the Securities
or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as is appropriate to reflect not only the
relative benefits referred to in clause (i) above but also the relative fault of
the Company on the one hand and the Underwriters on the other in connection with
the statements or omissions which resulted in such losses, claims, damages or
liabilities as well as any other relevant equitable considerations. The relative
benefits received by the Company on the one hand and the Underwriters on the
other shall be deemed to be in the same proportion as the total net proceeds
from the offering (before deducting expenses) received by the Company bear to
the total underwriting discounts and commissions received by the Underwriters.
The relative fault shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Underwriters and the parties' relative intent,
knowledge, access to information and







                                       17
<PAGE>   18

opportunity to correct or prevent such untrue statement or omission. The amount
paid by an indemnified party as a result of the losses, claims, damages or
liabilities referred to in the first sentence of this subsection (d) shall be
deemed to include any legal or other expenses reasonably incurred by such
indemnified party in connection with investigating or defending any action or
claim which is the subject of this subsection (d). Notwithstanding the
provisions of this subsection (d), no Underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which
the Securities underwritten by it and distributed to the public were offered to
the public exceeds the amount of any damages which such Underwriter has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. No person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this subsection (d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

         (e) The obligations of the Company under this Section shall be in
addition to any liability which the Company may otherwise have and shall extend,
upon the same terms and conditions, to each person, if any, who controls any
Underwriter within the meaning of the Act; and the obligations of the
Underwriters under this Section shall be in addition to any liability which the
respective Underwriters may otherwise have and shall extend, upon the same terms
and conditions, to each director of the Company, to each officer of the Company
who has signed a Registration Statement and to each person, if any, who controls
the Company within the meaning of the Act.

         8.   Default of Underwriters. If any Underwriter or Underwriters
default in their obligations to purchase Offered Securities hereunder on either
the First or any Optional Closing Date and the aggregate--principal
amount--number of shares--of Offered Securities that such defaulting Underwriter
or Underwriters agreed but failed to purchase does not exceed 10% of the
total--principal amount--number of shares--of Offered Securities that the
Underwriters are obligated to purchase on such Closing Date, CSFBC may make
arrangements satisfactory to the Company for the purchase of such Offered
Securities by other persons, including any of the Underwriters, but if no such
arrangements are made by such Closing Date, the non-defaulting Underwriters
shall be obligated severally, in proportion to their respective commitments
hereunder, to purchase the Offered Securities that such defaulting Underwriters
agreed but failed to purchase on such Closing Date. If any Underwriter or
Underwriters so default and the aggregate--principal amount--number of
shares--of Offered Securities with respect to which such default or defaults
occur exceeds 10% of the total--principal amount--number of shares--of Offered
Securities that the Underwriters are obligated to purchase on such Closing Date
and arrangements satisfactory to CSFBC and the Company for the purchase of such
Offered Securities by other persons are not made within 36 hours after such
default, this Agreement will terminate without liability on the part of any
non-defaulting Underwriter or the Company, except as provided in Section 9
(provided that if such default occurs with respect to Optional Securities after
the First Closing Date, this Agreement will not terminate as to the Firm
Securities or any Optional Securities purchased prior to such termination). As
used in this Agreement, the term "Underwriter" includes any person substituted
for an Underwriter under this Section. Nothing herein will relieve a defaulting
Underwriter from liability for its default.

         9.   Survival of Certain Representations and Obligations. The
respective indemnities, agreements, representations, warranties and other
statements of the Company or its officers and of the several Underwriters set
forth in or made pursuant to this Agreement will remain in full force and
effect, regardless of any investigation, or statement as to the results thereof,
made by or on behalf of any Underwriter, the Company or any of their respective
representatives, officers or directors or any controlling person, and will
survive delivery of and payment for the Offered Securities. If this Agreement is
terminated pursuant to Section 8 or if for any reason the purchase of the
Offered Securities by the Underwriters is not







                                       18
<PAGE>   19

consummated, the Company shall remain responsible for the expenses to be paid or
reimbursed by it pursuant to Section 5 and the respective obligations of the
Company and the Underwriters pursuant to Section 7 shall remain in effect, and
if any Offered Securities have been purchased hereunder the representations and
warranties in Section 2 and all obligations under Section 5 shall also remain in
effect. If the purchase of the Offered Securities by the Underwriters is not
consummated for any reason other than solely because of the termination of this
Agreement pursuant to Section 8 or the occurrence of any event specified in
clause (iii), (iv) or (v) of Section 6(c), the Company will reimburse the
Underwriters for all out-of-pocket expenses (including fees and disbursements of
counsel) reasonably incurred by them in connection with the offering of the
Offered Securities.

         10.  Notices. All communications hereunder will be in writing and, if
sent to the Underwriters, will be mailed, delivered or telegraphed and confirmed
to the Representatives, c/o Credit Suisse First Boston Corporation, Eleven
Madison Avenue, New York, NY 10010-3629, Attention: Investment Banking
Department--Transactions Advisory Group, or, if sent to the Company, will be
mailed, delivered or telegraphed and confirmed to it at 2300 Geng Road, Suite
200, Palo Alto, CA 94303, Attention: Roger Siboni; provided, however, that any
notice to an Underwriter pursuant to Section 7 will be mailed, delivered or
telegraphed and confirmed to such Underwriter.

         11.  Successors. This Agreement will inure to the benefit of and be
binding upon the parties hereto and their respective successors and the officers
and directors and controlling persons referred to in Section 7, and no other
person will have any right or obligation hereunder.

         12.  Representation of Underwriters. The Representatives will act for
the several Underwriters in connection with this financing, and any action under
this Agreement taken by the Representatives jointly or by CSFBC will be binding
upon all the Underwriters.

         13.  Counterparts. This Agreement may be executed in any number of
counterparts, each of which shall be deemed to be an original, but all such
counterparts shall together constitute one and the same Agreement.

         14.  Applicable Law. This Agreement shall be governed by, and construed
in accordance with, the laws of the State of New York, without regard to
principles of conflicts of laws.

         The Company hereby submits to the non-exclusive jurisdiction of the
Federal and state courts in the Borough of Manhattan in The City of New York in
any suit or proceeding arising out of or relating to this Agreement or the
transactions contemplated hereby.

         If the foregoing is in accordance with the Representatives'
understanding of our agreement, kindly sign and return to the Company one of the
counterparts hereof, whereupon it will become a binding agreement between the
Company and the several Underwriters in accordance with its terms.



                                       Very truly yours,

                                            E.PIPHANY, INC.

   [LETTERHEAD OF WILSON SONSINI GOODRICH & ROSATI, PROFESSIONAL CORPORATION]

                                August 19, 1999

E.piphany, Inc.

   RE: REGISTRATION STATEMENT ON FORM S-1

Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-1 filed by you with
the Securities and Exchange Commission ("SEC") on July 14, 1999 (Registration
No. 333-82799), as amended by Amendment No. 1 thereto filed with the SEC on
August 19, 1999 (the "Registration Statement"), in connection with the
registration under the Securities Act of 1933, as amended, of up to 4,600,000
shares of your Common Stock (the "Shares"). The Shares include an over-allotment
option granted to the underwriters of the offering to purchase 600,000 shares.
We understand that the Shares are to be sold to the underwriters of the offering
for resale to the public as described in the Registration Statement. As your
legal counsel, we have examined the proceedings taken, and are familiar with the
proceedings proposed to be taken, by you in connection with the sale and
issuance of the Shares.

     It is our opinion that, upon completion of the proceedings being taken or
contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares, including the proceedings being taken in order to permit such
transaction to be carried out in accordance with applicable state securities
laws, the Shares, when issued and sold in the manner described in the
Registration Statement and in accordance with the resolutions adopted by the
Board of Directors of the Company, will be legally and validly issued, fully
paid and nonassessable.

     We consent to the use of this opinion as an exhibit to the Registration
Statement and further consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus constituting a part thereof,
and any amendments thereto.

                                        Very truly yours,

                                        WILSON SONSINI GOODRICH & ROSATI

                                                                    EXHIBIT 10.1

                                 E.PIPHANY, INC.

                            INDEMNIFICATION AGREEMENT

        This Indemnification Agreement ("AGREEMENT") is entered into as of
____________, ___ by and between E.piphany, Inc. a Delaware corporation (the
"COMPANY") and ____________________________________ ("INDEMNITEE").

                                    RECITALS

        A. The Company and Indemnitee recognize the continued difficulty in
obtaining liability insurance for its directors, officers, employees, agents and
fiduciaries, the significant increases in the cost of such insurance and the
general reductions in the coverage of such insurance.

        B. The Company and Indemnitee further recognize the substantial increase
in corporate litigation in general, subjecting directors, officers, employees,
agents and fiduciaries to expensive litigation risks at the same time as the
availability and coverage of liability insurance has been severely limited.

        C. Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other directors,
officers, employees, agents and fiduciaries of the Company may not be willing to
continue to serve in such capacities without additional protection.

        D. The Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve the Company and, in part, in
order to induce Indemnitee to continue to provide services to the Company,
wishes to provide for the indemnification and advancing of expenses to
Indemnitee to the maximum extent permitted by law.

        E. In view of the considerations set forth above, the Company desires
that Indemnitee be indemnified by the Company as set forth herein.

        NOW, THEREFORE, the Company and Indemnitee hereby agree as follows:

        1.     Indemnification.

               (a) Indemnification of Expenses. The Company shall indemnify
Indemnitee to the fullest extent permitted by law if Indemnitee was or is or
becomes a party to or witness or other participant in, or is threatened to be
made a party to or witness or other participant in, any threatened, pending or
completed action, suit, proceeding or alternative dispute resolution mechanism,
or any hearing, inquiry or investigation that Indemnitee in good faith believes
might lead to

<PAGE>   2

the institution of any such action, suit, proceeding or alternative dispute
resolution mechanism, whether civil, criminal, administrative, investigative or
other (hereinafter a "Claim") by reason of (or arising in part out of) any event
or occurrence related to the fact that Indemnitee is or was a director, officer,
employee, agent or fiduciary of the Company, or any subsidiary of the Company,
or is or was serving at the request of the Company as a director, officer,
employee, agent or fiduciary of another corporation, partnership, joint venture,
trust or other enterprise, or by reason of any action or inaction on the part of
Indemnitee while serving in such capacity (hereinafter an "INDEMNIFIABLE EVENT")
against any and all expenses (including attorneys' fees and all other costs,
expenses and obligations incurred in connection with investigating, defending,
being a witness in or participating in (including on appeal), or preparing to
defend, be a witness in or participate in, any such action, suit, proceeding,
alternative dispute resolution mechanism, hearing, inquiry or investigation),
judgments, fines, penalties and amounts paid in settlement (if such settlement
is approved in advance by the Company, which approval shall not be unreasonably
withheld) of such Claim and any federal, state, local or foreign taxes imposed
on Indemnitee as a result of the actual or deemed receipt of any payments under
this Agreement (collectively, hereinafter "EXPENSES"), including all interest,
assessments and other charges paid or payable in connection with or in respect
of such Expenses. Such payment of Expenses shall be made by the Company as soon
as practicable but in any event no later than five days after written demand by
Indemnitee therefor is presented to the Company.

               (b) Reviewing Party. Notwithstanding the foregoing, (i) the
obligations of the Company under Section 1(a) shall be subject to the condition
that the Reviewing Party (as described in Section 10(e) hereof) shall not have
determined (in a written opinion, in any case in which the Independent Legal
Counsel referred to in Section 1(c) hereof is involved) that Indemnitee would
not be permitted to be indemnified under applicable law, and (ii) the obligation
of the Company to make an advance payment of Expenses to Indemnitee pursuant to
Section 2(a) (an "EXPENSE ADVANCE") shall be subject to the condition that, if,
when and to the extent that the Reviewing Party determines that Indemnitee would
not be permitted to be so indemnified under applicable law, the Company shall be
entitled to be reimbursed by Indemnitee (who hereby agrees to reimburse the
Company) for all such amounts theretofore paid; provided, however, that if
Indemnitee has commenced or thereafter commences legal proceedings in a court of
competent jurisdiction to secure a determination that Indemnitee should be
indemnified under applicable law, any determination made by the Reviewing Party
that Indemnitee would not be permitted to be indemnified under applicable law
shall not be binding and Indemnitee shall not be required to reimburse the
Company for any Expense Advance until a final judicial determination is made
with respect thereto (as to which all rights of appeal therefrom have been
exhausted or lapsed). Indemnitees' obligation to reimburse the Company for any
Expense Advance shall be unsecured and no interest shall be charged thereon. If
there has not been a Change in Control (as defined in Section 10(c) hereof), the
Reviewing Party shall be selected by the Board of Directors, and if there has
been such a Change in Control (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control), the Reviewing Party shall be the
Independent Legal Counsel referred to in Section 1(c) hereof. If there has been
no determination by the Reviewing Party or if the


                                      -2-
<PAGE>   3

Reviewing Party determines that Indemnitee substantively would not be permitted
to be indemnified in whole or in part under applicable law, Indemnitee shall
have the right to commence litigation seeking an initial determination by the
court or challenging any such determination by the Reviewing Party or any aspect
thereof, including the legal or factual bases therefor, and the Company hereby
consents to service of process and to appear in any such proceeding. Any
determination by the Reviewing Party otherwise shall be conclusive and binding
on the Company and Indemnitee.

               (c) Change in Control. The Company agrees that if there is a
Change in Control of the Company (other than a Change in Control which has been
approved by a majority of the Company's Board of Directors who were directors
immediately prior to such Change in Control) then, with respect to all matters
thereafter arising concerning the rights of Indemnitees to payments of Expenses
and Expense Advances under this Agreement or any other agreement or under the
Company's Certificate of Incorporation or Bylaws as now or hereafter in effect,
Independent Legal Counsel (as defined in Section 10(d) hereof) shall be selected
by Indemnitee and approved by the Company (which approval shall not be
unreasonably withheld). Such counsel, among other things, shall render its
written opinion to the Company and Indemnitee as to whether and to what extent
Indemnitee would be permitted to be indemnified under applicable law and the
Company agrees to abide by such opinion. The Company agrees to pay the
reasonable fees of the Independent Legal Counsel referred to above and to fully
indemnify such counsel against any and all expenses (including attorneys' fees),
claims, liabilities and damages arising out of or relating to this Agreement or
its engagement pursuant hereto.

               (d) Mandatory Payment of Expenses. Notwithstanding any other
provision of this Agreement other than Section 9 hereof, to the extent that
Indemnitee has been successful on the merits or otherwise, including, without
limitation, the dismissal of an action without prejudice, in defense of any
action, suit, proceeding, inquiry or investigation referred to in Section (1)(a)
hereof or in the defense of any claim, issue or matter therein, Indemnitee shall
be indemnified against all Expenses incurred by Indemnitee in connection
therewith.

        2.     Expenses; Indemnification Procedure.

               (a) Advancement of Expenses. The Company shall advance all
Expenses incurred by Indemnitee. The advances to be made hereunder shall be paid
by the Company to Indemnitee as soon as practicable but in any event no later
than five days after written demand by Indemnitee therefor to the Company.

               (b) Notice/Cooperation by Indemnitee. Indemnitee shall, as a
condition precedent to Indemnitees' right to be indemnified under this
Agreement, give the Company notice in writing as soon as practicable of any
Claim made against Indemnitee for which indemnification will or could be sought
under this Agreement. Notice to the Company shall be directed to the Chief
Executive Officer of the Company at the address shown on the signature page of
this Agreement (or such other address as the Company shall designate in writing
to Indemnitee). In


                                      -3-
<PAGE>   4

addition, Indemnitee shall give the Company such information and cooperation as
it may reasonably require and as shall be within Indemnitees' power.

               (c) No Presumptions; Burden of Proof. For purposes of this
Agreement, the termination of any Claim by judgment, order, settlement (whether
with or without court approval) or conviction, or upon a plea of nolo
contendere, or its equivalent, shall not create a presumption that Indemnitee
did not meet any particular standard of conduct or have any particular belief or
that a court has determined that indemnification is not permitted by applicable
law. In addition, neither the failure of the Reviewing Party to have made a
determination as to whether Indemnitee has met any particular standard of
conduct or had any particular belief, nor an actual determination by the
Reviewing Party that Indemnitee has not met such standard of conduct or did not
have such belief, prior to the commencement of legal proceedings by Indemnitee
to secure a judicial determination that Indemnitee should be indemnified under
applicable law, shall be a defense to Indemnitee's claim or create a presumption
that Indemnitee has not met any particular standard of conduct or did not have
any particular belief. In connection with any determination by the Reviewing
Party or otherwise as to whether Indemnitee is entitled to be indemnified
hereunder, the burden of proof shall be on the Company to establish that
Indemnitee is not so entitled.

               (d) Notice to Insurers. If, at the time of the receipt by the
Company of a notice of a Claim pursuant to Section 2(b) hereof, the Company has
liability insurance in effect which may cover such Claim, the Company shall give
prompt notice of the commencement of such Claim to the insurers in accordance
with the procedures set forth in the respective policies. The Company shall
thereafter take all necessary or desirable action to cause such insurers to pay,
on behalf of Indemnitee, all amounts payable as a result of such action, suit,
proceeding, inquiry or investigation in accordance with the terms of such
policies.

               (e) Selection of Counsel. In the event the Company shall be
obligated hereunder to pay the Expenses of any Claim, the Company shall be
entitled to assume the defense of such Claim with counsel approved by
Indemnitee, which approval shall not be unreasonably withheld, upon the delivery
to Indemnitee of written notice of its election so to do. After delivery of such
notice, approval of such counsel by Indemnitee and the retention of such counsel
by the Company, the Company will not be liable to Indemnitee under this
Agreement for any fees of counsel subsequently incurred by Indemnitee with
respect to the same Claim; provided that, (i) Indemnitee shall have the right to
employ Indemnitees' counsel in any such Claim at Indemnitee expense and (ii) if
(A) the employment of counsel by Indemnitee has been previously authorized by
the Company, (B) Indemnitee shall have reasonably concluded that there is a
conflict of interest between the Company and Indemnitee in the conduct of any
such defense, or (C) the Company shall not continue to retain such counsel to
defend such Claim, then the fees and expenses of Indemnitee counsel shall be at
the expense of the Company. The Company shall have the right to conduct such
defense as it sees fit in its sole discretion, including the right to settle any
claim against Indemnitee without the consent of the Indemnitee.

        3.     Additional Indemnification Rights; Nonexclusivity.


                                      -4-
<PAGE>   5


               (a) Scope. The Company hereby agrees to indemnify Indemnitee to
the fullest extent permitted by law, notwithstanding that such indemnification
is not specifically authorized by the other provisions of this Agreement, the
Company's Certificate of Incorporation, the Company's Bylaws or by statute. In
the event of any change after the date of this Agreement in any applicable law,
statute or rule which expands the right of a Delaware corporation to indemnify a
member of its Board of Directors or an officer, employee, agent or fiduciary, it
is the intent of the parties hereto that Indemnitee shall enjoy by this
Agreement the greater benefits afforded by such change. In the event of any
change in any applicable law, statute or rule which narrows the right of a
Delaware corporation to indemnify a member of its Board of Directors or an
officer, employee, agent or fiduciary, such change, to the extent not otherwise
required by such law, statute or rule to be applied to this Agreement, shall
have no effect on this Agreement or the parties' rights and obligations
hereunder except as set forth in Section 8(a) hereof.

               (b) Nonexclusivity. The indemnification provided by this
Agreement shall be in addition to any rights to which Indemnitee may be entitled
under the Company's Certificate of Incorporation, its Bylaws, any agreement, any
vote of stockholders or disinterested directors, the General Corporation Law of
the State of Delaware, or otherwise. The indemnification provided under this
Agreement shall continue as to Indemnitee for any action Indemnitee took or did
not take while serving in an indemnified capacity even though Indemnitee may
have ceased to serve in such capacity.

        4. No Duplication of Payments. The Company shall not be liable under
this Agreement to make any payment in connection with any Claim made against
Indemnitee to the extent Indemnitee has otherwise actually received payment
(under any insurance policy, Certificate of Incorporation, Bylaw or otherwise)
of the amounts otherwise indemnifiable hereunder.

        5. Partial Indemnification. If Indemnitee is entitled under any
provision of this Agreement to indemnification by the Company for some or a
portion of Expenses incurred in connection with any Claim, but not, however, for
all of the total amount thereof, the Company shall nevertheless indemnify
Indemnitee for the portion of such Expenses to which Indemnitee are entitled.

        6. Mutual Acknowledgement. Both the Company and Indemnitee acknowledge
that in certain instances, Federal law or applicable public policy may prohibit
the Company from indemnifying its directors, officers, employees, agents or
fiduciaries under this Agreement or otherwise. Indemnitee understands and
acknowledges that the Company has undertaken or may be required in the future to
undertake with the Securities and Exchange Commission to submit the question of
indemnification to a court in certain circumstances for a determination of the
Company's right under public policy to indemnify Indemnitee.

        7. Liability Insurance. To the extent the Company maintains liability
insurance applicable to directors, officers, employees, agents or fiduciaries,
Indemnitee shall be covered by


                                      -5-
<PAGE>   6

such policies in such a manner as to provide Indemnitee the same rights and
benefits as are accorded to the most favorably insured of the Company's
directors, if Indemnitee is a director; or of the Company's officers, if
Indemnitee is not a director of the Company but is an officer; or of the
Company's key employees, agents or fiduciaries, if Indemnitee is not an officer
or director but is a key employee, agent or fiduciary.

        8. Exceptions. Any other provision herein to the contrary
notwithstanding, the Company shall not be obligated pursuant to the terms of
this Agreement:

               (a) Excluded Action or Omissions. To indemnify Indemnitee for
Indemnitee's acts, omissions or transactions from which Indemnitee or the
Indemnitee may not be relieved of liability under applicable law;

               (b) Claims Initiated by Indemnitee. To indemnify or advance
expenses to Indemnitee with respect to Claims initiated or brought voluntarily
by Indemnitee and not by way of defense, except (i) with respect to actions or
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other agreement or insurance policy or under the Company's
Certificate of Incorporation or Bylaws now or hereafter in effect relating to
Claims for Indemnifiable Events, (ii) in specific cases if the Board of
Directors has approved the initiation or bringing of such Claim, or (iii) as
otherwise required under Section 145 of the Delaware General Corporation Law,
regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification, advance expense payment or insurance recovery, as the case may
be;

               (c) Lack of Good Faith. To indemnify Indemnitee for any expenses
incurred by Indemnitee with respect to any proceeding instituted by Indemnitee
to enforce or interpret this Agreement, if a court of competent jurisdiction
determines that each of the material assertions made by Indemnitee in such
proceeding was not made in good faith or was frivolous; or

               (d) Claims Under Section 16(b). To indemnify Indemnitee for
expenses and the payment of profits arising from the purchase and sale by
Indemnitee of securities in violation of Section 16(b) of the Securities
Exchange Act of 1934, as amended, or any similar successor statute.

        9. Period of Limitations. No legal action shall be brought and no cause
of action shall be asserted by or in the right of the Company against
Indemnitee, Indemnitee's estate, spouse, heirs, executors or personal or legal
representatives after the expiration of two years from the date of accrual of
such cause of action, and any claim or cause of action of the Company shall be
extinguished and deemed released unless asserted by the timely filing of a legal
action within such two-year period; provided, however, that if any shorter
period of limitations is otherwise applicable to any such cause of action, such
shorter period shall govern.

        10.    Construction of Certain Phrases.

               (a) For purposes of this Agreement, references to the "Company"
shall include, in addition to the resulting corporation, any constituent
corporation (including any constituent of a constituent) absorbed in a
consolidation or merger which, if its separate existence had continued, would
have had power and authority to indemnify its directors, officers, employees,
agents or fiduciaries, so that if Indemnitee is or was a director, officer,
employee, agent or fiduciary of such constituent corporation, or is or was
serving at the request of such constituent corporation as a director, officer,
employee, agent or fiduciary of another corporation, partnership, joint venture,
employee benefit plan, trust or other enterprise, Indemnitee shall stand in the
same position under the provisions of this Agreement with respect to the
resulting or surviving corporation as Indemnitee would have with respect to such
constituent corporation if its separate existence had continued.

               (b) For purposes of this Agreement, references to "other
enterprises" shall include employee benefit plans; references to "fines" shall
include any excise taxes assessed on Indemnitee with respect to an employee
benefit plan; and references to "serving at the request of the Company" shall
include any service as a director, officer, employee, agent or fiduciary of the
Company which imposes duties on, or involves services by, such director,
officer, employee, agent or fiduciary with respect to an employee benefit plan,
its participants or its beneficiaries; and if Indemnitee acted in good faith and
in a manner Indemnitee reasonably believed to be in the interest of the
participants and beneficiaries of an employee benefit plan, Indemnitee shall be
deemed to have acted in a manner "not opposed to the best interests of the
Company" as referred to in this Agreement.

               (c) For purposes of this Agreement a "Change in Control" shall be
deemed to have occurred if (i) any "person" (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended), other than
a trustee or other fiduciary holding securities under an employee benefit plan
of the Company or a corporation owned directly or indirectly by the stockholders
of the Company in substantially the same proportions as their ownership of stock
of the Company, (A) who is or becomes the beneficial owner, directly or
indirectly, of securities of the Company representing 10% or more of the
combined voting power of the Company's then outstanding Voting Securities,
increases his beneficial ownership of such securities by 5% or more over the
percentage so owned by such person, or (B) becomes the "beneficial owner" (as
defined in Rule 13d-3 under said Act), directly or indirectly, of securities of
the Company representing more than 20% of the total voting power represented by
the Company's then outstanding Voting Securities, (ii) during any period of two
consecutive years, individuals who at the beginning of such period constitute
the Board of Directors of the Company and any new director whose election by the
Board of Directors or nomination for election by the Company's stockholders was
approved by a vote of at least two-thirds of the directors then still in office
who either were directors at the beginning of the period or whose election or
nomination for election was previously so approved, cease for any reason to
constitute a majority thereof, or (iii)


                                      -7-
<PAGE>   8

the stockholders of the Company approve a merger or consolidation of the Company
with any other corporation other than a merger or consolidation which would
result in the Voting Securities of the Company outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into Voting Securities of the surviving entity) at least 80% of the
total voting power represented by the Voting Securities of the Company or such
surviving entity outstanding immediately after such merger or consolidation, or
the stockholders of the Company approve a plan of complete liquidation of the
Company or an agreement for the sale or disposition by the Company of (in one
transaction or a series of transactions) all or substantially all of the
Company's assets.

               (d) For purposes of this Agreement, "Independent Legal Counsel"
shall mean an attorney or firm of attorneys, selected in accordance with the
provisions of Section 1(c) hereof, who shall not have otherwise performed
services for the Company or Indemnitee within the last three years (other than
with respect to matters concerning the rights of Indemnitee under this
Agreement, or of other indemnitees under similar indemnity agreements).

               (e) For purposes of this Agreement, a "Reviewing Party" shall
mean any appropriate person or body consisting of a member or members of the
Company's Board of Directors or any other person or body appointed by the Board
of Directors who is not a party to the particular Claim for which Indemnitee are
seeking indemnification, or Independent Legal Counsel.

               (f) For purposes of this Agreement, "Voting Securities" shall
mean any securities of the Company that vote generally in the election of
directors.

        11. Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall constitute an original.

        12. Binding Effect; Successors and Assigns. This Agreement shall be
binding upon and inure to the benefit of and be enforceable by the parties
hereto and their respective successors, assigns, including any direct or
indirect successor by purchase, merger, consolidation or otherwise to all or
substantially all of the business and/or assets of the Company, spouses, heirs,
and personal and legal representatives. The Company shall require and cause any
successor (whether direct or indirect by purchase, merger, consolidation or
otherwise) to all, substantially all, or a substantial part, of the business
and/or assets of the Company, by written agreement in form and substance
satisfactory to Indemnitee, expressly to assume and agree to perform this
Agreement in the same manner and to the same extent that the Company would be
required to perform if no such succession had taken place. This Agreement shall
continue in effect with respect to Claims relating to Indemnifiable Events
regardless of whether Indemnitee continues to serve as a director, officer,
employee, agent or fiduciary of the Company or of any other enterprise at the
Company's request.


                                      -8-
<PAGE>   9

        13. Attorneys' Fees. In the event that any action is instituted by
Indemnitee under this Agreement or under any liability insurance policies
maintained by the Company to enforce or interpret any of the terms hereof or
thereof, Indemnitee shall be entitled to be paid all Expenses incurred by
Indemnitee with respect to such action, regardless of whether Indemnitee is
ultimately successful in such action, and shall be entitled to the advancement
of Expenses with respect to such action, unless, as a part of such action, a
court of competent jurisdiction over such action determines that each of the
material assertions made by Indemnitee as a basis for such action was not made
in good faith or was frivolous. In the event of an action instituted by or in
the name of the Company under this Agreement to enforce or interpret any of the
terms of this Agreement, Indemnitee shall be entitled to be paid all Expenses
incurred by Indemnitee in defense of such action (including costs and expenses
incurred with respect to Indemnitee counterclaims and cross-claims made in such
action), and shall be entitled to the advancement of Expenses with respect to
such action, unless, as a part of such action, a court having jurisdiction over
such action determines that each of Indemnitee material defenses to such action
was made in bad faith or was frivolous.

        14. Notice. All notices and other communications required or permitted
hereunder shall be in writing, shall be effective when given, and shall in any
event be deemed to be given (a) five (5) days after deposit with the U.S. Postal
Service or other applicable postal service, if delivered by first class mail,
postage prepaid, (b) upon delivery, if delivered by hand, (c) one business day
after the business day of deposit with Federal Express or similar overnight

the Indemnitee address as set forth beneath Indemnitee signatures to this
Agreement and if to the Company at the address of its principal corporate
offices (attention: Secretary) or at such other address as such party may
designate by ten days' advance written notice to the other party hereto.

        15. Consent to Jurisdiction. The Company and Indemnitee each hereby
irrevocably consent to the jurisdiction of the courts of the State of Delaware
for all purposes in connection with any action or proceeding which arises out of
or relates to this Agreement and agree that any action instituted under this
Agreement shall be commenced, prosecuted and continued only in the Court of
Chancery of the State of Delaware in and for New Castle County, which shall be
the exclusive and only proper forum for adjudicating such a claim.

        16. Severability. The provisions of this Agreement shall be severable in
the event that any of the provisions hereof (including any provision within a
single section, paragraph or sentence) are held by a court of competent
jurisdiction to be invalid, void or otherwise unenforceable, and the remaining
provisions shall remain enforceable to the fullest extent permitted by law.
Furthermore, to the fullest extent possible, the provisions of this Agreement
(including, without limitations, each portion of this Agreement containing any
provision held to be invalid, void or otherwise unenforceable, that is not
itself invalid, void or unenforceable) shall be


                                      -9-
<PAGE>   10

construed so as to give effect to the intent manifested by the provision held
invalid, illegal or unenforceable.

        17. Choice of Law. This Agreement shall be governed by and its
provisions construed and enforced in accordance with the laws of the State of
Delaware, as applied to contracts between Delaware residents, entered into and
to be performed entirely within the State of Delaware, without regard to the
conflict of laws principles thereof.

        18. Subrogation. In the event of payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee who shall execute all documents required and shall do
all acts that may be necessary to secure such rights and to enable the Company
effectively to bring suit to enforce such rights.

        19. Amendment and Termination. No amendment, modification, termination
or cancellation of this Agreement shall be effective unless it is in writing
signed by both the parties hereto. No waiver of any of the provisions of this
Agreement shall be deemed or shall constitute a waiver of any other provisions
hereof (whether or not similar) nor shall such waiver constitute a continuing
waiver.

        20. Integration and Entire Agreement. Subject to Indemnitee's rights
under Section 3(b) hereof, this Agreement sets forth the entire understanding
between the parties hereto and supersedes and merges all previous written and
oral negotiations, commitments, understandings and agreements relating to the
subject matter hereof between the parties hereto.

        21. No Construction as Employment Agreement. Nothing contained in this
Agreement shall be construed as giving Indemnitee any right to be retained in
the employ of the Company or any of its subsidiaries.

               (a)  Subject to and upon the terms and conditions of this
                    Agreement, at any time from the date hereof through March 1,
                    2000 (the "Non-Revolving Availability Date"), Bank agrees to

                    an aggregate outstanding amount not to exceed the
                    Non-Revolving Committed Line.

               (b)  Interest shall accrue from the date of each Non-Revolving

                    be payable monthly on the Payment Date for each month
                    through the month in which the Non-Revolving Availability
                    Date falls. Any Non-Revolving Advances that are outstanding
                    on the Non-Revolving Availability Date will be payable in
                    thirty-six (36) equal monthly installments of principal,
                    plus all accrued interest, beginning on the Payment Date of
                    each month following the Non-Revolving Availability Date and
                    ending on the Non-Revolving Maturity Date. Non-Revolving
                    Advances, once repaid, may not be reborrowed.

               (c)  When Borrower desires to obtain a Non-Revolving Advance,
                    Borrower shall notify Bank (which notice shall be
                    irrevocable) by facsimile transmission to be received no

                    Exhibit B. The notice shall be signed by a Responsible
                    Officer or its designee.

               5.   Section 2.3.1 entitled "Overadvances" is hereby amended and
                    restated to read in its entirety as follows:

                    Subject to the terms set forth in Section 2.1, if at any
                    time or for any reason, the outstanding principal amount of
                    Revolving Advances owed by Borrower to Bank pursuant to
                    Section 2.1, is greater than the lesser of the Committed
                    Line or the Borrowing Base, Borrower shall immediately pay
                    to Bank, in cash, the amount of such excess.

               6.   The following paragraph is hereby incorporated into Section
                    2.4 entitled "Interest Rates, Payments, and Calculations":

                    2.4(a)(iii) Non-Revolving Advances. Except as set forth in
                    Section 2.4(b), all Non-Revolving Advances shall bear
                    interest, on the average Daily Balance thereof, at a rate
                    equal to one half of one (0.50) percentage point above the
                    Prime Rate.

               7.   Section 6.3 entitled "Financial Statements, Reports,
                    Certificates" is hereby amended in part to provide that
                    Borrower's audited fiscal year end financial statements
                    shall be provided to Bank no later than 120 days (rather
                    than 90 days) after the end of Borrower's fiscal year.

               8.   Section 6.7 and all references thereto are hereby deleted in
                    its entirety.

               9.   Section 6.8 is hereby deleted and replaced with the
                    following:

                    6.8 Minimum Deposits.

                    Borrower shall maintain on deposit with Bank the lesser of
                    $4,000,000 or 100% of cash in the form of certificate of
                    deposits, money market accounts and/or checking accounts.
                    For any period in which the minimum balance requirement is
                    not kept, Borrower will pay to Bank a fee calculated at a
                    rate of one percent (1%) per annum, based on the difference
                    between the minimum required balance and the actual average
                    daily balance during the period. The fee will be calculated
                    quarterly and shall be due within 15 days of each quarter
                    end.

               10.  Section 6.9 entitled "Liquidity Coverage" is hereby amended
                    and restated in its entirety to read:

                    Borrower shall maintain, as of the last day of each calendar
                    month, a ratio of (a)(i) unrestricted cash and cash
                    equivalents plus (ii) 80% of Eligible Accounts minus (iii)
                    outstanding Revolving Advances of not less than (b)(i) two
                    (2) times the aggregate outstanding amount of all Equipment
                    Advances and Non-Revolving Advances under Section 2.2 and
                    2.3 through the month ending June 30, 1999, then (ii) 1.5
                    times the aggregate outstanding amount of all Equipment
                    Advances and Non-Revolving Advances under Section 2.2. and
                    2.3 through the month ending December 31, 1999, then (iii)
                    two (2) times the aggregate outstanding amount of all
                    Equipment Advances and Non-Revolving Advances under Section
                    2.2. and 2.3, thereafter. Notwithstanding the foregoing, at
                    such time as Borrower achieves a Debt Service Coverage ratio
                    of 1.50 to 1.00 for two (2) consecutive quarters, the
                    Liquidity Coverage shall be replaced by a Debt Service
                    Coverage ratio of 1.50 to 1.00, measured on a quarterly
                    basis.

                    quarterly profits (adjusted for capitalized development
                    costs) of at least $1.00, provided, however, Borrower may
                    suffer quarterly losses not to exceed:

                    $3,200,000 for the quarter ending December 31, 1998;
                    $3,000,000 for the quarter ending March 31, 1999;

below) understands and agrees that in modifying the existing Indebtedness, Bank
is relying upon Borrower's representations, warranties, and agreements, as set
forth in the Existing Loan Documents. Except as expressly modified pursuant to
this Loan Modification Agreement, the terms of the Existing Loan Documents

                                 PROMISSORY NOTE

$500,000 Principal Amount                                  Palo Alto, California

                                                                 August 15, 1998

     Roger S. Siboni ("Debtor") hereby promises to pay to the order of Epiphany
Marketing Software, Inc., a Delaware corporation ("Lender"), its successors and
assigns, in lawful money of the United States of America, the lesser of the
principal sum of FIVE HUNDRED THOUSAND DOLLARS ($500,000.00) (the "Maximum
Amount") or the principal balance outstanding under this Promissory Note,
together with accrued and unpaid interest thereon, at the rate or rates set
forth below, on the dates and in the amounts set forth below. Any prepayment
hereunder shall be applied first to the interest accrued and unpaid hereon and
then to the unpaid principal amount hereof.

     The unpaid principal amount of this Promissory Note shall bear interest at
a rate per annum equal to 5.6% compounded monthly. If any interest is determined
to be in excess of the then legal maximum rate, then that portion of each
interest payment representing an amount in excess of the then legal maximum rate
shall be deemed a payment of principal and applied against the principal of the
obligations evidenced by this Note.

     Subject to the terms and conditions hereof, the Lender agrees to make a
loan to Debtor that is automatically drawable monthly (on a calendar month
basis) for 24 consecutive months (each a "Monthly Draw" and collectively the
"Monthly Draws") from August 1998 through July 2000 unless Debtor's ceases to be
employed by Lender for any reason on or prior to July 31, 2000. If Debtor ceases
to be employed by Lender on or prior to July 31, 2000, the final Monthly Draw
payable under this Promissory Note shall be the Monthly Draw for Debtor's last
full calendar month of employment by Lender and the number of Monthly Draws
payable hereunder shall be reduced accordingly. Each Monthly Draw shall be in an
aggregate amount not to exceed $20,833.33 (the "Maximum Monthly Draw"), and
unless Debtor requests in writing a lesser amount, each Monthly Draw shall be
$20,833.33. The sum of the Monthly Draws in the aggregate shall not exceed the
Maximum Amount. A Monthly Draw in an amount less than the Maximum Monthly Draw
or a reduction in the number of Monthly Draws shall reduce the Maximum Amount by
a corresponding amount.

     The principal amount and accrued and unpaid interest under this Promissory
Note shall be payable in consecutive payments upon the Company's payment of any
annual bonus to Debtor. Debtor agrees that any annual bonus due to Debtor shall
first be applied to any principal balance and accrued and unpaid interest
outstanding under this Promissory Note. The debtor understands that he may not
receive any of his annual bonuses for many years because the full amount of his
annual bonuses will first be applied to any amount owed under this Promissory
Note.

     The principal amount and accrued and unpaid interest outstanding under this
Promissory Note shall become payable in full upon the earlier of (i) the date of
the first sale of any shares of

<PAGE>   2


stock of Lender obtained by Debtor by purchase from Lender (but not including
shares purchased through the exercise of stock options) or (ii) August 1, 2008
(the "Maturity Date").

     In the event Debtor shall fail to pay when due (whether at maturity, by
reason of acceleration or otherwise) any principal of or interest on this
Promissory Note, then (i) if such payment of principal or interest is not made
within 10 business days of the due date, then Lender may declare all obligations
(including without limitation, outstanding principal and accrued and unpaid
interest thereon) under this Promissory Note to be immediately due and payable
without presentment, demand, protest or any other notice of any kind, all of
which are hereby expressly waived and (ii) such overdue amounts shall bear
interest at a rate per annum equal to the otherwise applicable rate pursuant to
paragraph 2 above plus four percent (4%) per annum.

     The Lender will hold Debtor personally liable with full recourse for
payment of the obligations evidenced by this Promissory Note or for any other
sums due as a result of any defaults under this Promissory Note.

     Debtor hereby waives presentment, demand, notice of dishonor, protest,
notice of protest and all other demands, protests and notices in connection with
the execution, delivery, performance, collection and enforcement of this
Promissory Note. The Debtor shall pay all costs of collection when incurred,
including reasonable attorneys' fees, costs and expenses.

     This Promissory Note is being delivered in, is intended to be performed in,
shall be construed and interpreted in accordance with, and be governed by the
internal laws of, the State of California, without regard to principles of
conflict of laws.

     This Promissory Note may only be amended, modified or terminated by an
agreement in writing signed by the party to be charged. This Promissory Note
shall be binding upon the heirs, executors, administrators, successors and
assigns of the Debtor and inure to the benefit of the Lender and its permitted
successors, endorsees and assigns. This Promissory Note shall not be transferred
without the express written consent of Lender, provided that if Lender consents
to any such transfer or if notwithstanding the foregoing such a transfer occurs,
then the provisions of this Promissory Note shall inure to the benefit of and be
binding upon any successor to Debtor and shall be extended to any holder
thereof.
