                               PROSPECTUS SUMMARY

   You should read the following summary together with the more detailed
information regarding our company and the securities being sold in this
offering, together with the financial statements and related notes appearing
elsewhere in this prospectus.

                            Plumtree Software, Inc.

   We provide infrastructure software that brings together a wide range of
applications and information in a comprehensive Internet platform known as a
corporate portal. This platform, the Plumtree Corporate Portal, gives
employees, partners and customers a single, personalized destination for the
key information and services they need to do business with an organization. The
hallmark of this platform is its extensibility, which allows our customers and
alliance members to integrate in the portal electronic resources from other
corporate systems and the Internet. By combining these resources in a Web
experience that virtually everyone can understand, our platform enables
organizations to deliver new services to broad audiences quickly, create
greater returns on traditional applications and project a focused view of the
business for faster growth and better customer and partner support. We have
fortified our platform through alliances with over 80 technology vendors and
systems integrators. We have sold our software to more than 100 customers, with
licenses for 10,000 or more users at Andersen Consulting LLP, BP International
Limited, Ford Motor Company, Hy-Vee, Inc., Ketchum, Kmart Corporation,
Motorola, Inc. and The Procter & Gamble Company.

   The Internet has led to a proliferation of new online services, and opened
applications previously reserved for specialists to broader audiences. In
response to these changes in the business landscape, organizations are
investing substantial resources in Internet infrastructure software.
International Data Corporation, or IDC, estimates that the market for Internet
infrastructure software will grow at a compounded annual growth rate of 31%
from an estimated $9.4 billion in 1998 to $36.2 billion in 2003. To compete
effectively in this information-intensive environment, organizations are
seeking to give new classes of employees a complete view of the business, and
to provide customers and partners with a secure gateway to proprietary
information and services. Organizations' attempts to develop their own
solutions often fail to keep pace with the volume and variety of electronic
resources typically integrated in a corporate portal. Established software
vendors are Web-enabling their own applications, but are often limited by
architectures designed to process one type of data, and their applications
typically compete with other applications integrated in a portal. Emerging
software vendors may lack the product capabilities and partner support
necessary to offer a portal to a wide range of information and services.

   The Plumtree Corporate Portal is designed to bring together in a single
platform a broad range of electronic resources for the broadest possible
audience. The platform assembles information and services from disparate
systems in a personalized page, and organizes documents in an enterprise-wide
directory. We designed our platform to support enterprise-wide deployments to
hundreds of thousands of users, integrating thousands of different sources of
information and services. The platform is based on an open network architecture
for sharing the resources assembled by one portal with other businesses,
platforms and devices.

   Our objective is to lead the corporate portal market with the most
comprehensive, innovative portal technology, the broadest alliance network and
the most satisfied customers. To accomplish this, we intend to:

  . Establish our product as a platform for integrating all of an
    organization's existing resources on the Internet, and for delivering new
    services to that organization.

  . Build new alliances with technology vendors and systems integrators that
    can extend our platform to incorporate new types of information and
    services.

  . Increase our market share among industry-leading customers, increasing
    the number of users of our platform.

  . Capitalize on a network effect, selling our software to new customers
    that seek to exchange information and services with our existing
    customers.

   Our principal executive offices are located at 500 Sansome Street, San
Francisco, California 94111, and our telephone number is 415-263-8900. Our Web
site is www.plumtree.com. The information on our Web site does not constitute
part of this prospectus.

                                  RISK FACTORS

   You should carefully consider the risks described below and the other
information in this prospectus before deciding to invest in shares of our
common stock. If any of the following risks actually occur, our business could
be harmed, the trading price of our common stock could decline, and you may
lose all or part of your investment.

Risks Relating to Our Business

We have a short operating history, and, as a result, you may have difficulty
evaluating our business and operating results.

   We were founded in 1996 and began offering version 1.0 of our corporate
portal product in March 1998. We are now selling version 3.5 of the Plumtree
Corporate Portal. Version 4.0 of our product is scheduled for release in the
fourth quarter of 2000. We cannot predict whether this version of our product
will be successful. We have a short operating history, which makes the
evaluation of our business operations and our prospects difficult. We have
derived all of our revenue from licensing our Plumtree Corporate Portal product
and related services. Before buying our common stock, you should consider the
risks and difficulties frequently encountered by early stage companies in new
and rapidly evolving markets, particularly those companies whose businesses
depend on the Internet. These risks and difficulties, as they apply to us in
particular, include:

  . potential fluctuations in operating results and uncertain growth rates;

  . limited market acceptance of our products;

  . concentration of our revenue in a single product;

  . our need to expand our direct sales forces and indirect sales channels;

  . our need to manage rapidly expanding operations; and

  . our need to attract and train qualified personnel.

We have a history of losses, we expect future losses, and we may not be
profitable or maintain profitability in the future.

   We have incurred substantial net losses in each fiscal quarter since our
inception in July 1996 and do not expect to achieve profitability in the
foreseeable future. For the year ended December 31, 1999, we incurred net
losses of approximately $7.0 million, and for the six months ended June 30,
2000, we incurred net losses of approximately $6.3 million. As of June 30, 2000
we had an accumulated deficit of approximately $18.7 million. Given the level
of our planned operating and capital expenditures, we expect to incur losses
and negative cash flows for the foreseeable future.

   We may be unable to increase revenue or to achieve or maintain profitability
on a quarterly or annual basis, which may restrict our ability to pursue our
business strategy. Even if we ultimately do achieve profitability, we may not
be able to sustain or increase profitability on a quarterly or annual basis.
Our ability to increase revenue and achieve profitability also will be affected
by other risks and uncertainties described in this section and in "Management's
Discussion and Analysis of Financial Condition and Results of Operations." The
failure to attain profitability will have a harmful effect on our business and
the value of our common stock.

Our operating results in one or more future periods are likely to fluctuate
significantly, and if we fail to meet the expectations of securities analysts
or investors, our stock price could decline significantly.

   As a result of our limited operating history and the emerging nature of the
market in which we compete, we are unable to accurately forecast our revenue or
expenses. Our success is dependent upon our ability to enter into and maintain
strategic relationships with customers and to develop and maintain volume usage
of our

                                       6
<PAGE>

product by our customers. Our license revenue is comprised substantially of
one-time license fees. As a result, we will be required to regularly and
increasingly sign additional customers with substantial license fees on a
timely basis to realize comparable or increased license revenue.

   Our services and maintenance revenue historically has been comprised almost
entirely of installation, modification and consulting fees and support and
maintenance fees. Our services revenue has lower gross margin than our license
revenue. If the percentage of our services revenue increases compared to the
percentage of license revenue, our profitability would be impaired. Our
maintenance contracts are generally renewable for 12-month periods. If our
customers elect not to renew their maintenance contracts, our revenue could
decline.

   We expect to experience significant fluctuations in our future results of
operations due to a variety of factors, some of which are outside of our
control, including:

  . demand for and market acceptance of our products and services;

  . our expansion into international markets;

  . introduction of products and services and enhancements by us and our
    competitors;

  . competitive factors that affect our pricing;

  . changes in the mix of products and services we sell;

  . changes in the various sales channels through which our products and
    services are sold;

  . the timing and magnitude of our capital expenditures, including costs
    relating to the expansion of our operations;

  . the size and timing of customer orders, particularly large orders, some
    of which may represent more than 10% of total revenue during a particular
    quarter;

  . the size and timing of customer deployments;

  . the hiring and retention of key personnel; and

  . acquisitions that we complete or propose.

   As a result of these factors, we believe that quarter-to-quarter comparisons
of our revenue and operating results are not necessarily meaningful, and that
these comparisons may not be accurate indicators of future performance. Because
our staffing and operating expenses are based on anticipated revenue levels,
and because a high percentage of our costs are fixed, small variations in the
timing of the recognition of specific revenue could cause significant
variations in operating results from quarter to quarter. If we are unable to
adjust spending in a timely manner to compensate for any unexpected revenue
shortfall, any significant revenue shortfall would likely have an immediate
negative effect on our operating results. Moreover, our operating results in
one or more future quarters may fail to meet the expectations of securities
analysts or investors. If this occurs, we would expect to experience an
immediate and significant decline in the trading price of our stock.

Because our quarterly results often depend on a small number of large orders,
our quarterly operating results are difficult to forecast and may fluctuate.

   We derive a significant portion of our software license revenue in each
quarter from a small number of relatively large orders. For example, in each of
the last six quarters for the period ended June 30, 2000, we had at least one
customer that accounted for 10% or more of the total revenue for the quarter.
Our operating results could be harmed if we were unable to complete one or more
substantial license sales in any future period.

<PAGE>

Our business currently depends on revenue related to the Plumtree Corporate
Portal, and if the market does not increasingly accept this product and related
components, we may never become profitable.

   We generate our revenue from licenses and services related to the product
comprising the Plumtree Corporate Portal, including the Plumtree Portal
Gadgets, the building blocks from which users assemble a personalized page. We
expect that this product, and future upgraded versions of this product, will
continue to account for a large portion of our revenue in the foreseeable
future. Our future financial performance will depend on increasing acceptance
of our current product and on the successful development, introduction and
customer acceptance of new and enhanced versions of our product. If we fail to
deliver the enhancements to our product that customers want, demand for our
product and our revenue may decline.

Our sales and implementation cycles are long, unpredictable and subject to
seasonal fluctuations, making it difficult to accurately forecast our revenue.

   The typical sales cycle of our product can be long and unpredictable. A
successful sales cycle may last six months or longer, and typically includes
presentations to both business and technical decision makers. The
implementation of our product can be time-consuming and often involves a
significant commitment of resources by prospective customers. Accordingly, a
purchase decision for a potential customer typically requires the approval of
several senior decision makers, often requiring us to expend substantial
resources educating prospective customers about our software. Our sales cycle
is also affected by the business conditions of each prospective customer and
seasonal fluctuations as a result of customers' fiscal year budgeting and
purchasing cycles. This cycle is also subject to a number of significant delays
over which we have little or no control.

We depend on technology licensed from third-party software developers,
including Verity, Inc., and if we fail to maintain these license arrangements,
this could delay or impair our ability to develop and sell our product and
services.

   We incorporate into our product third-party software that enables the
functionality of our product. For example, we license our search engine, which
is integrated into the Plumtree Corporate Portal, from Verity. This third-party
software may not continue to be available on commercially reasonable terms or
with acceptable levels of support, or at all. Some of these third-party
software developers, including Verity, offer products that compete with the
Plumtree Corporate Portal. Our loss of or inability to maintain any of these
software licenses could delay or impair the sale of our product and services
until equivalent software, if available, is identified, licensed and
integrated, which could adversely affect our business and impair our future
growth.

We depend on our direct sales force to sell our product and if we fail to hire
and train new sales personnel, our future growth will be constrained.

   We primarily sell our product through our direct sales force and we expect
to continue to do so in the future. Our ability to achieve revenue growth in
the future will depend on our ability to recruit and train sufficient direct
sales personnel. We have in the past and may in the future experience
difficulty in recruiting qualified sales personnel. Our inability to rapidly
and effectively expand our direct sales force could impair our growth and cause
our stock price to fall.

If our alliances with systems integrators and resellers are discontinued, it
may be more difficult for us to maintain certain features of our product or
reach particular customers or markets.

   We have relationships with over 50 systems integrators and resellers to
provide our customers with rapid and comprehensive deployment of the Plumtree
Corporate Portal. Although our relationships are a key factor in our overall
business strategy, our alliance members may not view their relationships with
us as significant to their own businesses. A number of our competitors may have
stronger relationships with these systems integrators and, as a result, these
systems integrators may be more likely to recommend competitors' products and
services. Our arrangements generally rely on voluntary efforts of these systems
integrators and resellers. In addition, our agreements with these entities may
be terminated by either party with limited notice.

                                       8
<PAGE>

While we currently invest significant resources to develop these indirect sales
channels and plan to continue to do so, we may not succeed in establishing
channels that can market our product effectively and provide timely and cost-
effective customer support and services. If we are unable to maintain our
existing relationships or fail to enter into additional relationships, our
ability to increase our sales and reduce expenses will be harmed, and we could
also lose anticipated customer introductions and co-marketing benefits. Even if
we succeed in establishing these relationships, they may not result in
additional customers or revenues.

If our alliances with technology providers are discontinued, our future growth
will be impaired.

   We have relationships with technology providers to provide our customers
with robust support of many applications and services. Although these
relationships are a key factor in our overall business strategy, our alliance
members may not view their relationships with us as significant to their own
businesses. A number of our competitors may have stronger relationships with
these technology and content vendors, and, as a result, these alliance members
may be more likely to support our competitors' products and services. Our
arrangements generally do not establish minimum performance requirements but
instead rely on voluntary efforts. In addition, most of our agreements with
these entities may be terminated by either party with limited notice. We
currently invest significant resources to develop these alliances and plan to
continue to do so. If we are unable to maintain our existing relationships or
fail to enter into additional relationships, our ability to increase our sales
could be harmed, and we could also lose anticipated customer introductions and
co-marketing benefits. Even if we succeed in establishing these relationships,
they may not result in additional customers or revenue.

If our software contains errors, we may lose customers or experience reduced
market acceptance of our product.

   Our software product is inherently complex and may contain defects and
errors that are detected only when the product is in use. The latest version of
our product, version 4.0, has been introduced only very recently on a pilot-
basis, which increases the risk of undetected defects or errors. In addition,
third-party software that we incorporate into our product has contained, and
will in the future contain, defects or errors. Some of our Plumtree Corporate
Portal customers require, or may require, enhanced modifications of our
software for their specific needs. Modifications may increase the likelihood of
undetected defects or errors. Further, we often render implementation,
consulting and other technical services, the performance of which typically
involves working with sophisticated software, computing and networking systems.
As a result of product defects or failure to meet project milestones for
services, we may lose customers, customers may not implement our products more
broadly within their organization and we may experience product liability
claims and reduced market acceptance of our product.

If we are unable to develop products that are compatible and can be integrated
with a large variety of hardware, software, database and networking systems,
our ability to attract and retain customers will be harmed.

   The Plumtree Corporate Portal is designed to support a broad set of
enterprise applications and services through Plumtree Portal Gadgets. To gain
broad market acceptance, we believe that we must support an increased number of
applications and services in the future. If the underlying applications and
services are upgraded or changed, maintaining this support may be difficult or
impossible. If we are unable to support an increased number of applications and
services in the future or if we are unable to maintain compatibility with these
systems, our ability to attract and retain customers will be harmed.

                                       9

If we do not expand our customer base, we may never become profitable and our
stock price will likely decline.

   The market for corporate portal software is newly emerging and there can be
no assurance that additional customers will adopt our product. Accordingly, we
cannot accurately estimate the potential demand for our product and services.
We believe that market acceptance of our product and services depends
principally on our ability to:

  . effectively market the Plumtree Corporate Portal, related components and
    services;

  . hire, train and retain a sufficient number of qualified sales and
    marketing personnel;

  . provide high-quality and reliable customer support for our product;

  . distribute and price our product and services in a manner that is more
    appealing to customers than that of our competitors;

  . develop a favorable reputation among our customers, potential customers
    and participants in the software industry; and

  . withstand downturns in general economic conditions or conditions that
    slow corporate spending on software products.

   Some of these factors are beyond our control. If our customer base does not
expand, we may never become profitable.

Customers in a preliminary phase of implementing our product may not proceed on
a timely basis or at all.

   Some of our customers are currently in a pre-deployment or pre-launch stage
of implementing our product and may encounter delays or other problems in
introducing it. A customer's decision not to implement our product, or a delay
in implementation, could result in a delay or loss in related revenue or
otherwise harm our business and prospects. We cannot predict when any customer
that is currently in a pilot or preliminary phase will implement broader use of
our product.

Security breaches with our software may lead to unexpected capital expenditures
and cause a loss in revenue and reputation.

   Our product is also designed to facilitate the secure transmission of
sensitive business information to specified parties outside the business over
the Internet. This includes product information, competitive intelligence,
sales and inventory data, sales reports and corporate e-mail. As a result, the
reputation of our software product for providing security is vital to their
acceptance by customers. Our product may be vulnerable to theft or other
improper activity that could jeopardize the security of information for which
we are responsible. Problems caused by security breaches could result in loss
of or delay in revenue, loss of market share, failure to achieve market
acceptance, diversion of research and development resources, harm to our
reputation, customer claims against us, increased insurance costs or increased
service and warranty costs.

Capacity restrictions of our software could reduce the demand for and use of
our product, which may limit our ability to generate license revenue.

   Our product is designed to support enterprise-wide deployments with hundreds
of thousands of users. However, the amount of information and the number of
concurrent users that our product can support in any particular deployment is
uncertain. If the capacity boundaries are reached, our customers may be
dissatisfied with our product, and we may lose customers or fail to gain new
customers.

If we are unable to retain key personnel, our growth will be limited.

   We are highly dependent on certain members of our management staff,
including, without limitation, our Chief Executive Officer, John Kunze, our
Vice President of Product Development, John Hogan, and our Vice

                                       10
<PAGE>

President of Worldwide Field Operations, Jim Flatley. The loss of one or more
of these officers might impede the achievement of our business objectives.

If we are unable to hire and integrate new personnel, our operations will be
disrupted and our growth impaired.

   Recruiting and retaining qualified technical personnel is critical to our
success. If our business grows, we will also need to recruit a significant
number of management, technical and other personnel for our business.
Competition for employees in our industry is intense, particularly in the
Silicon Valley region of Northern California where our principal offices are
located. If we are not able to continue to attract and retain skilled and
experienced personnel on acceptable terms, our growth may be limited due to our
limited capacity to develop and market our product. We are currently recruiting
personnel for technical, marketing, sales and administrative functions. Once
hired, these people will need time to familiarize themselves with Plumtree and
our business practices. We expect to continue to hire additional employees in
order to grow our business. The integration of new personnel has resulted and
will continue to result in some disruption to our ongoing operations. Our
failure to complete this integration in an efficient manner could harm our
business and prospects.

Managing the growth of our operations will continue to strain managerial,
operational and financial resources.

   The planned expansion of our operations will place a significant strain on
our management, financial controls, operations systems, personnel and other
resources. Our ability to manage our future growth, should it occur, will
depend in large part upon a number of factors, including our ability to
rapidly:

  . build and train our sales and marketing staff to create an expanding
    presence in the evolving corporate portal market, and keep them fully
    informed over time regarding the technical features, issues and key
    selling points of our product;

  . develop our customer support capacity as sales of our product grow, so
    that we can provide customer support without diverting resources from
    product development efforts; and

  . expand our internal management and financial controls significantly, so
    that we can maintain control over our operations and provide support to
    other functional areas within Plumtree as the number of our personnel and
    size of our organization increases.

   Our inability to achieve any of these objectives could harm our business,
operating results and financial condition.

We may be unable to grow our international operations, which could impair our
overall growth.

   Our revenue from sales outside the United States constituted less than 3% of
our total revenue during 1999 and approximately 4.6% of our total revenue for
the six months ended June 30, 2000. We have expanded our international
operations, and we are seeking to increase the portion of our revenue that is
derived from sources outside the United States. If we are unable to grow our
international operations, we may not generate sufficient revenue to offset the
expenditures required to establish and maintain the international sales and
marketing operations, which could slow or undermine our overall growth.

   We also expect to commit additional resources to modify our product for
selected international markets, including Europe and Asia, and developing
international sales and support organizations. However, even if we successfully
expand our international operations and successfully modify our product, there
can be no assurance that we will be able to maintain or increase international
market demand for our product.

   Our international operations are subject to a number of risks, including:

  . costs of modifying our product for foreign countries;

                                       11
<PAGE>

  . compliance with multiple, conflicting and changing foreign governmental
    laws and regulations, including intellectual property, securities and
    employment laws;

  . longer sales cycles;

  . import and export restrictions and tariffs;

  . fluctuations in foreign currency exchange rates;

  . difficulties in staffing and managing international operations; and

  . greater difficulty or delay in accounts receivable collection.

Product liability claims could divert management's attention and be costly to
defend.

   Our license agreements with customers typically contain provisions designed
to limit our exposure to potential product liability claims. Not all domestic
and international jurisdictions may enforce these limitations. Although we have
not experienced any product liability claims to date, we may encounter this
type of claim in the future. Product liability claims brought against us,
whether or not successful, could divert the attention and resources of our
management and key personnel, could be costly to defend and could require us to
pay significant monetary damages.

If we are unable to effectively protect our proprietary rights, our competitors
may be able to copy important aspects of our product or product presentation,
which would undermine the relative appeal of our product to customers and
reduce our sales.

   We believe that proprietary rights are important to our business. We have
filed one provisional patent application with the U.S. Patent and Trademark
Office. However, our current or future patent applications may not be granted,
and it is possible that any patents issued to us may be circumvented by our
competitors or otherwise may not provide significant protection or commercial
advantage to us. Similarly, our trademark, service mark and copyright rights
may not provide significant protection or commercial advantage to us, and the
measures we take to maintain the confidentiality of our trade secrets may not
be effective.

   Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy or otherwise obtain and use our software product or
technology without authorization. Policing unauthorized use of our product is
difficult, and we cannot be certain that the steps we have taken will prevent
misappropriation of our technology, particularly in foreign countries where the
laws may not protect our proprietary rights as fully as those in the United
States.

   We generally enter into confidentiality or license agreements with our
employees, consultants and corporate partners, control access to our source
code and other proprietary technology and limit distribution of our software,
documentation and other proprietary information. These measures afford only
limited protection and may be inadequate. Others may develop noninfringing
technologies that are similar or superior to our own.

If our product employs technology that infringes the proprietary rights of
others, we may be forced to pay high prices to license technology or stop
selling our product.

   We expect that software products may be increasingly subject to third-party
infringement claims as the number of competitors in our industry segment grows
and the functionality of products in different industry segments expands and
overlaps. Third parties may claim our product infringes their intellectual
property rights. Regardless of whether these claims have any merit, they could:

  . be time-consuming to defend;

  . result in costly litigation;

  . divert our management's attention and resources;

                                       12
<PAGE>

  . require us to indemnify alliance members or customers;

  . cause product shipment delays; or

  . require us to enter into royalty or licensing agreements, which may not
    be available on terms acceptable to us, if at all.

   A successful claim of infringement against us or our failure or inability to
license the infringed or similar technology could damage our business because
we could be required to pay substantial monetary damages and would not be able
to sell our product without redeveloping them or otherwise incurring
significant additional expenses.

We may be subject to misappropriation claims by former employers of our
personnel, which could be costly and disruptive to our business.

   From time to time, we hire or retain employees or consultants who have
worked for independent software vendors or other companies developing products
similar to those offered by us. Those prior employers may claim that our
product is based on their products and that we have misappropriated their
intellectual property. Any claims of that variety, with or without merit, could
cause a significant diversion of management attention, result in costly and
protracted litigation, cause product shipment delays or require us to enter
into royalty or licensing agreements. Those royalty or licensing agreements, if
required, may not be available on terms acceptable to us or at all, which could
harm our business.

Acquisitions of companies or technologies may result in disruptions to our
business and management due to difficulties in assimilating personnel and
operations.

   We may make acquisitions or investments in other companies or technologies.
We may not realize the anticipated benefits of any acquisition or investment.
If we make any acquisitions, we will be required to assimilate the operations,
products and personnel of the acquired businesses and train, retain and
motivate key personnel from the acquired businesses. We may be unable to
maintain uniform standards, controls, procedures and policies if we fail in
these efforts. Similarly, acquisitions may cause disruptions in our operations
and divert management's attention from day-to-day operations, which could
impair our relationships with our current employees, customers and strategic
partners. In addition, our profitability may suffer because of acquisition-
related costs, amortization costs for acquired goodwill and other intangible
assets, or undisclosed liabilities of the acquired business.

We will need significant additional funds, which we may be unable to obtain on
terms acceptable to us or at all.

   The expansion and development of our business will require significant
capital to fund our operating expenses, working capital needs and capital
expenditures. During the next 18 months, we expect to meet our cash
requirements with existing cash and cash equivalents and short-term
investments, the net proceeds from this offering, cash flow from sales of our
product and services and proceeds from existing and future working capital
lines of credit and other borrowings. Our failure to generate sufficient cash
flows from sales of product and services or to raise sufficient funds may
require us to delay or abandon some or all of our development and expansion
plans or otherwise forego market opportunities.

   Future equity or debt financing may not be available to us on favorable
terms or at all. The terms of our existing loan agreement with Silicon Valley
Bank limits our ability to incur additional indebtedness. Future borrowing
instruments, such as credit facilities and lease agreements, are also likely to
contain restrictive covenants and will likely require us to pledge assets as
security for borrowings under those future arrangements. If we raise additional
funds through the issuance of equity securities, the issuance could result in
substantial dilution to existing stockholders. Our inability to obtain
additional capital on satisfactory terms may

                                       13
<PAGE>

result in a delay or failure to develop and enhance our products, acquire new
technologies or businesses, expand operations and hire and train employees.

Risks Relating to Our Industry

Intense competition and consolidation in our industry could limit our ability
to attract and retain customers.

   The market for our product is intensely competitive and highly fragmented,
characterized by rapid technological change, evolving industry standards and
changes in customer needs, and new product introductions and improvements. Our
current competitors include established software vendors that are Web-enabling
their applications or are building infrastructure software, emerging companies
offering competitive products and companies choosing to build their own
solutions. Many of our competitors have longer operating histories,
significantly greater financial, technical, marketing and other resources,
greater name recognition, a broader range of products and a larger installed
customer base, any of which could provide them with a significant competitive
advantage. In addition, new competitors, or alliances among existing and future
competitors, may emerge and rapidly gain significant market share. If we are
unable to compete successfully against current and future competitors, we may
be unable to attract and retain customers. Increased competition could also
result in price reductions for our product and lower profit margins and reduced
market share, any of which could harm our business, results of operations and
financial condition.

Difficulties in introducing new products and enhancements in a timely manner
will make market acceptance of our products less likely.

   New products, platforms and language support can require long development
and testing periods. Any delays in developing and releasing new products could
harm our business. New products or enhancements may not be released according
to schedule or may contain defects when released. For example, version 4.0 of
our product has been developed only very recently, which increases the risk of
undetected defects or errors. Either situation could result in adverse
publicity, loss of sales, delay in market acceptance of our products or
customer claims against us, any of which could harm our business. We may be
unable to successfully develop and market product enhancements or new products
that respond to these technological changes, shifting customer tastes or
evolving industry standards, and may experience difficulties that could delay
or prevent the successful development, introduction and marketing of these
products. If we are unable to develop and introduce new products or
enhancements of existing products in a timely manner or if we experience delays
in the commencement of commercial shipments of new products and enhancements,
our ability to attract and retain customers will be harmed.

If we fail to manage technological change, demand for our product and services
will drop and our revenue will decline.

   The market for corporate portals is still in an early stage of development
and is characterized by rapidly changing technology, evolving industry
standards, frequent new service and product introductions and changes in
customer demands. Our future success will depend to a substantial degree on our
ability to offer products and services that incorporate leading technologies
and respond to technological advances and emerging industry standards and
practices on a timely and cost-effective basis. You should be aware that:

  . our technology or systems may become obsolete upon the introduction of
    alternative technologies;

  . the technological life cycles of our product are difficult to estimate;

  . we may not have sufficient resources to develop or acquire new
    technologies or to introduce new services capable of competing with
    future technologies or service offerings; and

  . the price of the products and services we provide may decline as rapidly
    as, or more rapidly than, the price of any competitive alternatives.

                                       14
<PAGE>

   We may not be able to effectively respond to the technological requirements
of the changing market for corporate portals. To the extent we determine that
new technologies and equipment are required to remain competitive, the
development, acquisition and implementation of those technologies and equipment
are likely to continue to require significant capital investment by us. We may
not have sufficient capital for this purpose in the future, and even if
available, investments in new technologies may not result in commercially
viable technological processes and there may not be commercial applications for
those technologies. If we do not develop and introduce new products and
services, and achieve market acceptance in a timely manner, demand for our
products and services will drop and our revenue will decline.

If we fail to adequately respond to changes in customer needs, our ability to
attract and retain customers will suffer.

   We expect that our customers increasingly will demand additional information
and reports with respect to the services we provide. To meet these demands, we
must develop and implement expanded customer support services to enable future
sales growth. In addition, if we are successful in implementing our marketing
strategy, we expect the demands on our technical support resources to grow
rapidly, and we may experience difficulties in responding to customer demand
for our services and providing technical support in accordance with our
customers' expectations. We expect that these demands will require not only the
addition of new management personnel, but also the development of additional
expertise by existing management personnel and the establishment of long-term
relationships with third-party service vendors. If we are unable to address
these customer demands, our ability to attract and retain customers will
suffer.

Risk Relating to this Offering

Future sales of common stock could depress our stock price.

   We cannot predict if future sales of our common stock, or the availability
of our common stock for sale, will depress the market price for our common
stock or adversely affect our ability to raise capital by offering equity
securities. Sales of substantial amounts of common stock, or the perception
that these sales could occur, may depress prevailing market prices for the
common stock.

   After this offering, approximately      shares of common stock will be
outstanding. All of the shares sold in this offering will be freely tradeable
except for any shares purchased by affiliates of Plumtree. The remaining shares
of common stock outstanding after this offering will be restricted as a result
of securities laws or lock-up agreements. These remaining shares will be
available for sale in the public market as follows:

   Credit Suisse First Boston Corporation may release all or a portion of the
shares subject to lock-up agreements at any time without notice. See
"Underwriting" and "Shares Eligible for Future Sale."

Stock prices of infrastructure software companies are especially volatile, and
this volatility may depress our stock price.

   We cannot predict the extent to which investor interest in Plumtree will
lead to the development of a trading market or how liquid that market might
become. Before this offering, there has been no public market for our common
stock. We intend to list the common stock on the Nasdaq National Market. The
initial public offering price for the shares of our common stock will be
determined by negotiations between us and the representatives of the
underwriters and may not be indicative of prices that will prevail in the
trading market. The stock market has experienced significant price and volume
fluctuations and the market prices of securities

                                       15
<PAGE>

of infrastructure software companies have been highly volatile. You may not be
able to resell your shares at or above the initial public offering price or at
all. See "Underwriting."

   In the past, following periods of volatility in the market price of a
company's securities, securities class action litigation has often been
instituted against the company. The institution of this type of litigation
against us could result in substantial costs and a diversion of our
management's attention and resources, which could harm our business and
prospects.

Our stock ownership will continue to be concentrated in the hands of management
and existing stockholders, which could adversely affect our business and
depress our stock price.

   Upon completion of this offering, our present directors, executive officers
and principal stockholders as a group will beneficially own approximately     %
of the outstanding common stock (    % if the underwriters' over-allotment
option is exercised). Accordingly, if all or particular stockholders were to
act together, they would be able to exercise significant influence over or
control the election of our board of directors, the management and policies of
our company and the outcome of particular corporate transactions or other
matters submitted to our stockholders for approval, including mergers,
consolidations and the sale of all or substantially all of our assets.

Anti-takeover provisions in our certificate of incorporation and bylaws could
discourage or prevent an acquisition of our company, and could affect the price
of our common stock.

   Provisions of the certificate of incorporation and bylaws that we intend to
adopt before the closing of this offering may inhibit changes of control that
are not approved by our board of directors. These include provisions
classifying our board of directors, prohibiting stockholder action by written
consent and requiring advance notice for nomination of directors and
stockholders' proposals. In addition, as a Delaware corporation, we will be
subject to Section 203 of the Delaware General Corporation Law which, in
general, prevents an interested stockholder, defined generally as a person
owning 15% or more of the corporation's outstanding voting stock, from engaging
in a business combination, as defined, for three years following the date that
person became an interested stockholder unless specified conditions are
satisfied. Our certificate of incorporation and bylaw provisions and Delaware
law could diminish the opportunities for a stockholder to participate in tender
offers, including tender offers at prices above the then-current fair market
value of our common stock, that could result from takeover attempts. In
addition, our certificate of incorporation will allow our board of directors to
issue, without further stockholder approval, preferred stock that could have
the effect of delaying, deferring or preventing a change in control. The
issuance of preferred stock also could adversely affect the voting power of the
holders of our common stock, including the loss of voting control to others.
The provisions of our certificate of incorporation and bylaws, as well as
provisions of Delaware law, may have the effect of discouraging or preventing
an acquisition, or disposition of, our business. These provisions could limit
the price that investors might be willing to pay in the future for shares of
our common stock.

Our management has broad discretion over the use of proceeds from this
offering, and the failure of management to apply these funds effectively could
seriously harm our business and results of operations.

   We have not determined and cannot predict in which, if any, of our existing
or future opportunities we will ultimately invest. Therefore, we have broad
discretion as to how we spend the proceeds from this offering, and stockholders
may not agree with how we use the proceeds. We may not be successful in using
the proceeds from this offering in ways that will yield favorable results. See
"Use of Proceeds."

                 SPECIAL NOTE ABOUT FORWARD-LOOKING STATEMENTS

   Some of the matters discussed under the captions "Prospectus Summary," "Risk
Factors," "Management's Discussion and Analysis of Financial Condition and
Results of Operations," "Business" and elsewhere in this prospectus include
forward-looking statements. We have based these forward-looking statements on
our current expectations and projections about future events, including, among
other things:

  . implementing our business strategy;

  . attracting and retaining customers and employees;

  . obtaining and expanding market acceptance of the products and services we
    offer;

  . forecasts of Internet usage and the size and growth of relevant markets;

  . rapid technological changes in our industry and relevant markets; and

  . competition in our market.

   In some cases, you can identify forward-looking statements by terminology
such as "may," "will," "should," "could," "predicts," "potential," "continue,"
"expects," "anticipates," "future," "intends," "plans," "believes," "estimates"
and similar expressions. These statements are based on our current beliefs,
expectations and assumptions and are subject to a number of risks and
uncertainties. Actual results, levels of activity, performance, achievements
and events may vary significantly from those implied by the forward-looking
statements. A description of risks that could cause our results to vary appears
under the caption "Risk Factors" and elsewhere in this prospectus. These
forward-looking statements are made as of the date of this prospectus, and we
assume no obligation to update them or to explain the reasons why actual
results differ.

<PAGE>

                                USE OF PROCEEDS

   We estimate that we will receive net proceeds of approximately $
million from the sale of shares of our common stock in this offering. If the
underwriters exercise their over-allotment option in full, we estimate that we
will receive total net proceeds of approximately $      million. These net
proceeds amounts are based upon an assumed initial public offering price of
$      per share and after deducting estimated underwriting discounts and
commissions and estimated offering expenses. The principal purposes of this
offering are to obtain additional capital, to facilitate future access by us to
public equity markets and to provide increased visibility and credibility in
the marketplace.

   We expect to use the net proceeds from this offering for general corporate
purposes, including working capital. We may also use a portion of the net
proceeds to acquire complementary products, technologies or businesses;
however, we currently have no commitments or agreements relating to any such
transactions.

   We do not have more specific plans for the net proceeds from this offering.
The amounts and timing of any expenditures will vary depending on the amount of
cash generated by our operations, competitive and technological developments
and the rate of growth, if any, of our business. As a result, we will retain
broad discretion in the use of the net proceeds of this offering. Investors
will be relying on the judgment of our management regarding the application of
the proceeds of this offering. Pending use of the net proceeds as discussed
above, we intend to invest these funds in short-term, interest-bearing,
investment-grade obligations.

                                DIVIDEND POLICY

   We have never declared or paid dividends on our capital stock. We presently
anticipate that we will retain all of our future earnings to finance the
development and expansion of our business and provide working capital.
Therefore, we do not anticipate paying any cash dividends on our common stock
for the foreseeable future. The terms of our existing Silicon Valley Bank loan
and security agreement prohibit the payment of dividends, except in specified
circumstances.

                                    DILUTION

Pro forma net tangible book value

   The pro forma net tangible book value of our common stock was approximately
$20.5 million, or approximately $0.86 per share, on June 30, 2000. We
calculated pro forma net tangible book value assuming that warrants for 212,168
shares of preferred stock and 143,641 shares of common stock will be exercised
and all outstanding shares of preferred stock will convert into common stock
when the offering is completed. Pro forma 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 stock outstanding.

Dilution after this offering

   Dilution in net tangible book value per share represents the difference
between the amount per share paid by purchasers of our common stock in this
offering and the net tangible book value per share of our common stock
immediately after this offering.

   Assuming our sale of            shares of common stock offered by this
prospectus at an assumed initial public offering price of $      per share, and
after deducting estimated underwriting discounts and commissions and estimated
offering expenses, our pro forma net tangible book value at June 30, 2000 would
have been approximately $      million or $      per share. This represents an
immediate increase in net tangible book value of $      per share to the
existing stockholders and an immediate dilution of $      per share to new
investors purchasing common stock in this offering.

   The table below illustrates this per share dilution:

Differences between new and existing stockholders in number of shares and
amount paid

   The table below summarizes, on a pro forma basis, as of June 30, 2000, the
differences between the number of shares of common stock purchased from us, the
total consideration paid and the average price per share paid by existing
stockholders and by the new investors purchasing shares in this offering. We
used an assumed initial public offering price of $       per share, and we have
not deducted estimated underwriting discounts and commissions and estimated
offering expenses in our calculations.

</TABLE>

   If the underwriters exercise the over-allotment in full:

  . the number of shares of common stock hold by existing stockholders will
    decrease to approximately       % of the total number of shares of our
    outstanding common stock; and

  . the number of shares held by new investors will increase to           ,
    or approximately       % of the total number of shares of our common
    stock outstanding after completion of this offering.

   Except as indicated, the foregoing discussion and tables assume no exercise
of any stock options or warrants outstanding. As of August 31, 2000, there
were:

  . 4,948,630 shares of common stock issuable upon exercise of options
    outstanding as of August 31, 2000, at a weighted average exercise price
    of $1.51 per share;

  . 11,446,333 additional shares of common stock available for issuance under
    our stock option plans;

  . 1,000,000 shares of common stock available for issuance under our
    employee stock purchase plan; and

  . 355,809 shares of common stock issuable upon exercise of warrants
    outstanding, at a weighted average exercise price of $0.50 per share.

The exercise of options or warrants outstanding having an exercise price less
than the initial public offering price would increase dilution to new
investors.

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

   The following discussion should be read in conjunction with the Financial
Statements and related notes that appear elsewhere in this prospectus. The
following discussion contains forward-looking statements that reflect our
plans, estimates and beliefs. Our actual results could differ materially from
those discussed in the forward-looking statements. Factors that could cause or
contribute to these differences include, but are not limited to, those
discussed below and elsewhere in this prospectus, particularly in "Risk
Factors."

Overview

 General

   We provide infrastructure software that brings together a wide range of
applications and information in a comprehensive Internet platform known as a
corporate portal. From our inception in 1996 through the beginning of 1998, we
were engaged primarily in developing and marketing our corporate portal
product. In March 1998, we released version 1.0 of the Plumtree Corporate
Portal. As part of our strategy, we seek to continually enhance the
functionality of our software, and subsequently released version 2.0 in
November 1998, version 3.0 in June 1999 and version 3.5 in February 2000.
Version 4.0 of our portal is scheduled for release in the fourth quarter of
2000.

 Sources of Revenue

   We derive our revenue from software licenses, services and maintenance. To
date, substantially all of our revenue has been derived through direct sales.
We have recently focused on building our indirect sales channel. Our services
include installation, consulting and training. We plan to rely increasingly on
third-party consulting organizations to deliver these services. Maintenance
services include technical support and software updates. Maintenance contracts
are typically one year in duration and can be renewed annually.

 Revenue Recognition

   License revenue is recognized when a contract is executed, all shipment
obligations have been met, collection of the fee is fixed or determinable and
collectibility is probable. When licenses are sold together with services,
license fees are recognized upon shipment, provided that (1) the preceding
criteria have been met, (2) payment of the license fees is not dependent upon
the performance of the services and (3) the services do not include significant
modifications to the features and functionality of the software.

   For arrangements in which payment of license fees are dependent upon the
performance of services, both the license revenue and service revenue are
recognized in accordance with the provisions of Statement of Position ("SOP")
81-1, "Accounting for Performance of Construction Type and Certain Production
Type Contracts." Under this method, license and services revenue is recognized
as the services are performed.

   For arrangements which require delivery of unspecified future products over
a period, we recognize revenue ratably over the term of the arrangement.

   Services revenue is recognized as the services are performed and consists of
consulting, training and installation services that we provide to our
customers. If services are bundled with a license agreement, amounts related to
services are unbundled from the license fee based on vendor specific objective
evidence as established by transactions where such services have been sold
separately.

   Maintenance revenue relates to providing technical support and software
updates. Maintenance revenue is recognized ratably over the term of the related
contract, generally one year. Unrecognized maintenance fees are included in
deferred revenue. If maintenance is bundled with a license agreement, amounts
related to maintenance are unbundled from the license fee based on vendor
specific objective evidence as established by transactions where such
maintenance services have been sold separately.

                                       23

 Amortization of Stock-Based Compensation

   In connection with stock option grants to our employees and others, we have
recorded stock-based compensation totaling approximately $10.8 million as of
June 30, 2000. This amount represents the difference between the exercise price
and the deemed fair market value of our common stock for accounting purposes on
the date we granted these stock options. This amount is included as a component
of stockholders' equity and is being amortized on an accelerated basis by
charges to earnings from operations over the vesting period of the options,
generally four years. For 1999, we recorded $325,000 of stock-based
compensation amortization expense. For the six months ended June 30, 2000, we
recorded approximately $1.1 million of stock-based compensation amortization
expense. The amortization of the remaining stock-based compensation will result
in additional charges to earnings from operations in 2001 and thereafter.

   An important part of our strategy is to expand our operations and employee
base and build our sales, marketing, customer support and technical resources.
As of June 30, 2000 we had 152 full-time employees and we intend to hire a
significant number of employees in the future. Our planned expansion places
significant demands on our management and operational resources. To manage this
growth, we will continue to invest in and implement scalable operational
systems, procedures and controls. As of June 30, 2000, we had an accumulated
deficit of approximately $18.7 million. We expect to continue to incur
operating losses for the foreseeable future.

Results of Operations

   The following table sets forth the statements of operations data for each of
the periods indicated as a percentage of total revenue. Data for the period
from inception (July 18, 1996) to December 31, 1996 and for the year ended
December 31, 1997 is not presented because we had no material revenue during
those periods.

Six Months Ended June 30, 1999 and 2000

Revenue

   Revenue increased from $685,000 for the six months ended June 30, 1999 to
approximately $8.8 million for the six months ended June 30, 2000.

   Licenses. Licenses revenue increased from $635,000 for the six months ended
June 30, 1999 to approximately $5.9 million for the six months ended June 30,
2000. The increase in license revenue was primarily due to the addition of 52
new license customers.

   Services and Maintenance. Services and maintenance revenue increased from
$50,000 for the six months ended June 30, 1999 to approximately $2.9 million
for the six months ended June 30, 2000. This increase was the result of an
increase in services and maintenance provided in connection with license sales,
and the absence of paid services in some of our earlier contracts. This
increase included approximately $500,000 in additional maintenance revenue and
approximately $2.4 million in additional professional services, training and
other revenue.

Cost of Revenue

   Our cost of revenue includes licenses, services and maintenance costs. Cost
of revenue increased from $211,000 for the six months ended June 30, 1999 to
approximately $3.4 million for the six months ended June 30, 2000. Cost of
revenue as a percent of revenue increased from 32% of total revenue for the six
months ended June 30, 1999 to 39% for the six months ended June 30, 2000. This
change is primarily the result of increased cost of maintenance and
professional services, which were 95% of total cost of revenue for the six
months ended June 30, 2000.

   Licenses. Our cost of licenses consists of royalty expenses paid to a third-
party technology vendor. Costs of licenses increased from $16,000 for the six
months ended June 30, 1999 to $161,000 for the six months ended June 30, 2000.

   Services and Maintenance. Our cost of services and maintenance includes
salaries and related expenses for our professional service organization, third
party consultants and technical support organization. Cost of services and
maintenance increased from $195,000 for the six months ended June 30, 1999 to
approximately $3.3 million for the six months ended June 30, 2000. This
increase was primarily due to a substantial increase in the number of
professional services staff in conjunction with increased demand for our
product. Historically, cost of services and maintenance has exceeded services
and maintenance revenue, and we expect this trend to continue over the near
term.

Operating Expenses

   Research and Development. Research and development expenses consist of new
software development, the costs associated with our in-house development staff
and contract software developers. The costs associated with this in-house
development staff consist primarily of salaries, as well as other related
expenses. From time to time, this in-house development staff is supported by
outside developers on a contractual basis. The costs for the development of new
software products and substantial enhancements to existing software products
that are eligible for capitalization have not been significant to date and, as
such, are expensed as research and development costs in the period in which
they are incurred. Research and development expenses increased from $675,000
for the six months ended June 30, 1999 to approximately $1.9 million for the
six months ended June 30, 2000. This increase was primarily due to an increase
in the number of research and development staff. We expect our research and
development expenses to increase in future periods as we continue to improve
our software products.

   Sales and Marketing. Sales and marketing expenses consist of payroll
expense, including salaries and commissions and related costs for sales and
marketing personnel, and promotion expenditures, including public relations,
advertising and trade shows. Sales and marketing expenses increased from
approximately $2.0 million for the six months ended June 30, 1999 to
approximately $6.5 million for the six months ended June 30, 2000.

                                       26
<PAGE>

This increase was primarily due to an increase in the number of sales and
marketing personnel. We expect our sales and marketing expenses to increase as
we continue to increase our marketing efforts and expand our direct and
indirect sales forces.

   General and Administrative. General and administrative expenses consist
primarily of salaries for administrative, executive and finance personnel,
recruiting costs and information services costs. General and administrative
expenses increased from $600,000 for the six months ended June 30, 1999 to
approximately $2.3 million for the six months ended June 30, 2000. This
increase was primarily due to increases in facilities expense, the number of
personnel and professional services fees. We expect that our general and
administrative expenses will continue to increase as we expand our operations
and incur additional costs related to being a public company.

   Amortization of Stock-Based Compensation. In connection with options granted
to employees, directors and consultants during the six months ended June 30,
1999 and June 30, 2000 we recorded stock-based compensation representing the
difference between the exercise price of options granted and the deemed fair
market value of our common stock at the date of grant. Amortization of stock-
based compensation was $42,000 for the six months ended June 30, 1999 and
approximately $1.1 million for the six months ended June 30, 2000.

Other Income (Expense), Net

   Other income (expense), net, primarily includes interest income from our
cash and cash equivalents, and investments. Interest expense relates to our
financing obligations, including bank borrowings. Other income (expense), net,
was $94,000 of interest expense for the six months ended June 30, 1999 and
$60,000 of interest income for the six months ended June 30, 2000. This
increase was primarily due to a higher average cash balance as a result of the
proceeds from the issuance of shares of our preferred stock in August 1999 and
May 2000.

Years Ended December 31, 1997, 1998 and 1999

Revenue

   Revenue was $181,000 in 1998 and approximately $3.4 million in 1999. We did
not recognize any revenue in 1997.

   Licenses. Licenses revenue was $166,000 in 1998 and approximately $2.7
million in 1999. The increase was due primarily to increased market acceptance
of the Plumtree Corporate Portal.

   Services and Maintenance. Services and maintenance revenue was $15,000 in
1998 and $653,000 in 1999. The increase was attributable primarily to an
increase in services and support provided in connection with increased license
sales and growth of our customer base.

Cost of Revenue

   Cost of revenue was $19,000 in 1998 and approximately $1.2 million in 1999.
We did not recognize any cost of revenue in 1997 and only limited costs in
1998.

   Licenses. Cost of licenses revenue was $90,000 in 1999. We had no cost of
license revenue in 1997 or 1998 due to the limited revenue, if any, recognized
in these periods.

   Services and Maintenance. Cost of services and maintenance revenue was
$19,000 in 1998 and approximately $1.1 million in 1999. We had no cost of
services and maintenance revenue in 1997.

Operating Expenses

   Research and Development. Research and development expenses were $635,000 in
1997, approximately $1.1 million in 1998 and approximately $1.7 million in
1999. These increases were primarily due to the addition of personnel in our
research and development department over these periods.

                                       27
<PAGE>

   Sales and Marketing. Sales and marketing expenses were $575,000 in 1997,
approximately $2.4 million in 1998 and approximately $5.6 million in 1999.
These increases were attributable primarily to hiring additional sales and
marketing and customer support employees over these periods as well as
increased promotional costs.

   General and Administrative. General and administrative expenses were
$386,000 in 1997, $445,000 in 1998 and approximately $1.4 million in 1999.
These increases were due primarily to hiring administrative personnel,
professional expenses for legal and accounting support, depreciation expenses
for new office equipment and amortization of improvements to our San Francisco
offices.

   Amortization of Stock-Based Compensation. In connection with the granting
of options to purchase our common stock to certain employees, directors and
consultants during the year ended December 31, 1999, we recorded stock-based
compensation representing the difference between the exercise price of options
granted and the deemed fair market value of our common stock at the time of
grant. Amortization of stock-based compensation in the year ended December 31,
1999 was $325,000. For the years ended December 31, 1998 and 1997 we recorded
no stock-based compensation.

Other Income (Expense), Net

   Other income (expense), net, was $22,000 in 1997, $28,000 in 1998 and an
expense of $151,000 in 1999.

Provision for Income Taxes

   From inception through June 30, 2000, we incurred net losses for federal
and state tax purposes and have not recognized any tax provision or benefit.
Given our losses incurred through June 30, 2000, our losses projected for the
remainder of fiscal 2000 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 the deferred income tax asset. See Note 11 of Notes to our
Financial Statements for the components for the deferred income tax asset.

Quarterly Results of Operations

   The following tables set forth selected unaudited statements of operations
data for the six quarters ended June 30, 2000. This data has been derived from
the unaudited interim financial statements prepared on the same basis as the
audited financial statements prepared in accordance with generally accepted
accounting principles contained herein and, in the opinion of management,
include all adjustments consisting only of normal recurring adjustments that we
consider necessary for a fair presentation of such information when read in
conjunction with the financial statements and notes thereto appearing elsewhere
in this prospectus. The operating results for any quarter should not be
considered indicative of results of any future period.

</TABLE>

   Our quarterly revenue increased throughout the periods presented primarily
as a result of the introduction of new versions of the Plumtree Corporate
Portal and the substantial growth of our direct sales force. Cost of revenue
has increased in each quarter primarily as a result of hiring new professional
services employees. Total operating expense has 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,
and increased spending on research and development to support new product
introductions and an increase in general and administrative expenses to manage
our expanding operations.

   Quarterly research and development expenses substantially increased from the
quarter ended June 30, 1999 to the quarter ended September 30, 1999 as a result
of significant hiring to develop version 3.5 of our product. Research and
development expenses for the quarter ended December 31, 1999 did not increase
at the rate of the previous quarter primarily due to a slower rate of growth in
personnel. General and administrative expenses increased from the quarter ended
December 31, 1999 to the quarter ended March 31, 2000 due to increased
professional services fees, implementation of a new financial software system
and the addition of new employees.

                                       29
<PAGE>

   As a result of our limited operating history and the emerging nature of the
market in which we compete, we are unable to accurately forecast our revenue or
expenses. Our success is dependent upon our ability to enter into and maintain
strategic relationships with customers and to develop and maintain volume usage
of our products by our customers. Our license revenue is comprised
substantially of one-time license fees. As a result, we will be required to
regularly and increasingly sign additional customers with substantial license
fees on a timely basis to realize comparable or increased license revenue.

   Our services and maintenance revenue historically has been comprised almost
entirely of installation, modification and consulting fees and support and
maintenance fees. Our services revenue has lower gross margin than our license
revenue. If the percentage of our services revenue increases compared to the
percentage of license revenue, our profitability would be impaired. Our
maintenance contracts are generally renewable for 12-month periods. If our
customers elect not to renew their maintenance contracts, our revenue could
decline.

   We expect to experience significant fluctuations in our future results of
operations due to a variety of factors, some of which are outside of our
control, including:

  . demand for and market acceptance of our products and services;

  . our expansion into international markets;

  . introduction of products and services and enhancements by us and our
    competitors;

  . competitive factors that affect our pricing;

  . changes in the mix of products and services we sell;

  . changes in the various sales channels through which our products and
    services are sold;

  . the timing and magnitude of our capital expenditures, including costs
    relating to the expansion of our operations;

  . the size and timing of customer orders, particularly large orders, some
    of which may represent more than 10% of total revenue during a particular
    quarter;

  . the size and timing of customer deployments;

  . the hiring and retention of key personnel; and

  . acquisitions that we complete or propose.

   As a result of these factors, we believe that quarter-to-quarter comparisons
of our revenue and operating results are not necessarily meaningful, and that
these comparisons may not be accurate indicators of future performance. Because
our staffing and operating expenses are based on anticipated revenue levels,
and because a high percentage of our costs are fixed, small variations in the
timing of the recognition of specific revenue could cause significant
variations in operating results from quarter to quarter. If we are unable to
adjust spending in a timely manner to compensate for any unexpected revenue
shortfall, any significant revenue shortfall would likely have an immediate
negative effect on our operating results. Moreover, our operating results in
one or more future quarters may fail to meet the expectations of securities
analysts or investors. If this occurs, we would expect to experience an
immediate and significant decline in the trading price of our stock.

Liquidity and Capital Resources

   Since inception, we have primarily financed our operations and capital
expenditures through the private sales of convertible preferred stock, with net
proceeds of approximately $36.5 million, as well as through bank loans and
equipment leases. We had approximately $14.9 million of cash and cash
equivalents and approximately $17.4 million in working capital as of June 30,
2000.

                                       30
<PAGE>

   Our net cash used in operating activities was approximately $1.4 million in
1997, $3.8 million in 1998, $6.9 million in 1999 and $9.4 million for the six
months ended June 30, 2000. The increase in cash used in operating activities
was due primarily to our net loss excluding non-cash charges (consisting
principally of depreciation and amortization of stock-based compensation) and
our working capital investments. Our working capital investments consist
principally of accounts receivable and prepaid expenses. Our accounts
receivable fluctuations are principally due to the significant size of some
individual software licensing agreements and the applicable method of revenue
recognition. Prepaid expenses are primarily related to advance payments made to
technology vendors and deposits on future trade shows.

   Capital expenditures were $34,000 in 1997, $230,000 in 1998, $134,000 in
1999 and $416,000 for the six months ended June 30, 2000. Our capital
expenditures consisted of purchases of items to manage our operations,
including computer hardware and software, office furniture and equipment and
leasehold improvements. We expect that our capital expenditures will continue
to increase in the future.

   Our net cash provided by convertible preferred stock financing activities
was approximately $2.6 million in 1997, $4.0 million in 1998, $8.0 million in
1999 and $22.0 million for the six months ended June 30, 2000. Upon completion
of this offering, our outstanding convertible preferred stock will
automatically convert into common stock. For the six months ended June 30,
2000, we also generated $580,000 of cash from the exercise of stock options.

   In April 1998, we entered into a loan and security agreement with Silicon
Valley Bank, amended in July 1998, whereby Silicon Valley Bank will make us one
or more non-revolving loans in an aggregate principal amount of up to $750,000.
To secure these loans, we have granted Silicon Valley Bank a security interest
in all of our assets. The loans and other amounts due under this agreement
mature on July 31, 2001. Interest on the loans are payable monthly and accrue
at one percentage point above the prime rate as announced by Silicon Valley
Bank. As of June 30, 2000, we had $216,000 outstanding under the loan and
security agreement. We are prohibited from declaring and paying dividends and
incurring any non-permitted indebtedness under our loan agreements with Silicon
Valley Bank.

   In addition, we entered into a master equipment lease agreement with
Lighthouse Capital Partners II, L.P. whereby Lighthouse Capital will provide
funds to us under a lease line schedule in an aggregate principal amount of up
to $500,000. The lease line schedule is to be used only to finance or refinance
purchases of equipment.

   We expect to experience significant growth in our operating expenses,
particularly research and development and sales and marketing expenses, for the
foreseeable future in order to execute our business plan. As a result, we
anticipate that these operating expenses, as well as planned capital
expenditures, will constitute a material use of our cash resources. In
addition, we may utilize cash resources to fund acquisitions of complementary
businesses, technologies or product lines. We believe that our net proceeds
from this offering, expected proceeds of $702,000 from the exercise of warrants
just prior to the completion of this offering, together with cash and cash
equivalents on hand, will be sufficient to meet our cash requirements for at
least the next 18 months, including working capital requirements and planned
capital expenditures. We may require additional funds for other purposes, and
these additional financing sources may not be available or, if available, the
financing may not be attainable on terms favorable to us.

Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board 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 effective in achieving offsetting changes in fair value or cash flows.
In June 1999,

                                       31
<PAGE>

the FASB issued SFAS No. 137, "Accounting for Derivative Instruments and
Hedging Activities--Deferral of the Effective Date of FASB Statements 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 the Company). In
June 2000, the FASB issued Statement No. 138, "Accounting for Certain
Derivative Instruments and Certain Hedging Activities--an Amendment of FASB
Statement No. 133." SFAS 138 amends SFAS 133 to (a) exclude from the scope of
SFAS No. 133 nonfinancial assets that will be delivered in quantities expected
to be used or sold by a company over a reasonable period in the normal course
of business and for which physical delivery is probable, (b) permit hedging of
a benchmark interest rate, (c) allow hedging of foreign-currency-denominated
assets and liabilities and (d) allow for limited hedging of net foreign
currency exposures. We have no derivative financial and commodity instruments,
forward contracts or hedging arrangements in cash and cash equivalents. These
statements should not have a material impact on our financial condition or
results of operations.

   In December 1998, the AICPA issued 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 98-3 by extending the deferral of the application of
certain provisions of SOP 97-2 amended by SOP 98-3 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. These statements will not have a material impact on our financial
condition or results of operations.

   In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial
Statements." SAB 101 provides guidance on applying generally accepted
accounting principles to revenue recognition issues in financial statements. We
have adopted SAB 101 as required for the filing of this initial public
offering.

   In March 2000, the FASB issued FASB Interpretation No. 44, "Accounting for
Certain Transactions Involving Stock Compensation (an Interpretation of APB
Opinion No. 25)" ("FIN 44"). FIN 44 provides guidance on the application of APB
25, particularly as it relates to options. The effective date of FIN 44 is
July 1, 2000 and we have adopted FIN 44 as of that date.

Quantitative and Qualitative Disclosures About Market Risk

   As of June 30, 2000, we had cash and cash equivalents of approximately $14.9
million, which consist of cash and highly liquid short-term investments with
original maturities of three months or less at the date of purchase. These
investments may be subject to interest rate risk and will decrease in value if
market interest rates increase. A hypothetical increase or decrease in market
interest rates by 10% from the market interest rates at June 30, 2000 would
cause the fair value of these short-term investments to change by an immaterial
amount. Declines in interest rates over time will, however, reduce our interest
income.

                                    BUSINESS

Overview

   We provide infrastructure software that brings together a wide range of
applications and information in a comprehensive Internet platform known as a
corporate portal. This platform, the Plumtree Corporate Portal, gives
employees, partners and customers a single, personalized destination for the
key information and services they need to do business with an organization. The
hallmark of this platform is its extensibility, which allows our customers and
alliance members to integrate in the portal electronic resources from other
corporate systems and the Internet. By combining these resources in a Web
experience that virtually everyone can understand, the platform enables
organizations to deliver new services to broad audiences quickly, create
greater returns on traditional applications and project a focused view of the
business for faster growth and better customer and partner support. We have
fortified our platform through alliances with over 80 technology vendors and
systems integrators. We have sold our software to more than 100 customers, with
licenses for 10,000 or more users at Andersen Consulting LLP, BP International
Limited, Ford Motor Company, Hy-Vee, Inc., Ketchum, Kmart Corporation,
Motorola, Inc. and The Procter & Gamble Company.

Industry Background

   The Internet has transformed business, introducing broader audiences to
computing, opening enterprises to new relationships with customers and
partners, and creating connections between formerly isolated business systems.
The volume of information and the number of applications available via the
Internet have increased dramatically. Businesses are devoting substantial
investments to integrate and distribute information to and from the Internet.
International Data Corporation, or IDC, estimates that the market for Internet
infrastructure software will grow at a compounded annual growth rate of 31%
from an estimated $9.4 billion in 1998 to $36.2 billion in 2003.

   Many organizations are seeking to combine their most important information,
applications and Internet-based services into a single destination for everyone
who does business with the organization. The first challenge is to integrate
enterprise applications, such as sales databases and financial systems,
purchased at different times for different purposes, whose audience has been
limited to technical or functional specialists. The second challenge is to
create an enterprise-wide framework for organizing the enormous volume of
documents, e-mail messages, and Web pages now being created with desktop
publishing tools and personal computers. The third challenge is to combine
these resources with e-business applications, which are often initiated as
projects separate from an organization's technology infrastructure. These
challenges impair the ability of organizations to assemble a complete view of
their businesses on the Internet.

   Creating a focal point for an organization's most important information and
services has a new urgency because the Internet has so greatly expanded their
potential users. To build a competitive workforce, many companies are now using
the Internet to reach all of their employees worldwide. Similarly, customers
and partners who do not want to visit multiple sites to do business with one
organization need a single point of access for all the electronic information
and services available from that organization. These organizations often lack
the infrastructure for assembling information and services from different
systems into a simple, powerful experience that can be delivered to a factory
floor kiosk, a salesperson's mobile device or a business partner's desktop.

   There have been few solutions for integrating in one Web platform a wide
range of resources from other systems. Attempts to develop in-house solutions
often are costly, require significant resources and time, and provide limited
functionality. Emerging software vendors developing products focused on solving
these problems may lack the product capabilities and partner support necessary
to integrate many systems into a complete view of the business. Established
software vendors are Web-enabling their own applications, but often face
architectural limitations when attempting to integrate data and services from
other applications. In addition, many of these vendors are unlikely to support
access to data or services provided by an application from a competing vendor.

                                       33
<PAGE>

   As a result of these trends, there exists a significant market for
infrastructure software that can combine an organization's most important
information and online services in a single Internet platform known as a
corporate portal. A corporate portal is a Web portal to information,
applications and Internet-based services.

Our Solution

   We provide infrastructure software and services that enable a business to
deploy a corporate portal to information, applications and Internet-based
services. The Plumtree Corporate Portal is an open, scalable platform that
gives a broad audience of employees, partners and customers a single,
personalized destination for the key information and services they need to do
business with an organization.

   Our extensible platform, our proprietary Massively Parallel Portal Engine
and our network of customers and alliance members are the foundation of our
corporate portal solution. Our extensible platform enables customers and
alliance members to develop plug-in components known as Plumtree Portal Gadgets
to integrate a wide variety of applications and services into the portal.
Together with our customers and alliance members, we have developed hundreds of
gadgets for integrating resources from a broad range of applications. The
Massively Parallel Portal Engine processes user requests for these resources
from multiple computers in parallel, to support large-scale, enterprise-wide
deployments with hundreds of thousands of users. This open architecture allows
customers to share the information and services assembled by one portal
deployment with other portal deployments, and with other Internet platforms and
devices, connecting alliance members and customers in a network that we refer
to as the Plumtree Portal Network. As a result, new customers can draw upon an
extensive set of shared services, and distribute their own resources to a broad
range of businesses. The Massively Parallel Portal Engine is a feature
contained in version 4.0 of our product, which is scheduled to be released in
the fourth quarter of 2000.

   This solution offers the following benefits to our customers:

 Creates a Focused View of the Business

   Our product is designed to assemble a comprehensive and dynamic view of the
business. Rather than having to negotiate access to a wide range of
applications and services to be productive, users can see everything relevant
to their work in a personalized portal page. This experience is particularly
powerful at orienting new employees to the information and services available
from the organization. A new salesperson may, for example, begin each day with
a portal page that includes sales leads from a database, e-mail and calendar
from a communication system, competitive updates from a marketing department
and the Internet, and an electronic form for sending marketing materials to
prospects. This experience was designed to help employees be more effective at
driving revenue, and allow the organization to grow faster.

 Extends the Business Enterprise to Partners and Customers

   As a portal for business people outside a company, our product provides a
secure forum for drawing customers and partners into the enterprise. For
example, a company's sales partner could visit the company's portal to check
inventory, search for support articles, query market demographics or share
sales leads. In addition, version 4.0 of our product includes a community
experience that allows organizations and their customers or partners to
collaborate. As a result, the customer or partner can work more closely with
the organization, creating opportunities for increased sales and better
service.

 Accelerates Time-to-Benefit of New Applications and Services

   Our platform's extensible architecture allows new applications and services
to be integrated into the portal, which can accelerate their deployment and
increase their impact. We believe the portal can become the standard interface
for our customers' electronic data and services. In place of costly and time-
consuming rollouts of new systems, our customers can embed applications and
services from those systems in a portal that

                                       34
<PAGE>

a large number of users already visits daily, immediately creating a
constituency that increases the likelihood of a successful deployment and
accelerates the impact of the new applications and services on the business.

 Leverages Existing Technology Investments

   Our product opens applications to broader audiences without requiring
changes to those applications. Applications previously limited to technical
specialists deliver more value in a portal that everyone visits. Widespread use
throughout the extended enterprise increases the return on a broad legacy of
applications in a new, cohesive e-business setting.

Strategy

   Our objective is to lead the corporate portal industry with the most
innovative technology, broadest alliance network and most satisfied customers.
To achieve our goal, we are pursuing the following strategies:

 Establish the Plumtree Corporate Portal as a Platform

   We intend to establish the Plumtree Corporate Portal as the primary platform
for aggregating the information and services available to a company. To drive
this strategy, we seek to maximize the range of applications integrated into
our platform. Beyond traditional enterprise systems, we are integrating new
e-business services, including transactional systems from vendors such as
Ariba, business process software from vendors such as webMethods, collaboration
capabilities from vendors such as eRoom and Web content management capabilities
from vendors such as Vignette. We also seek to develop new distribution
capabilities based on our technology for syndicating gadget content to other
platforms and mobile devices. To accomplish this objective, we intend to
establish alliances with vendors of wireless services, voice portals and other
Web platforms. By delivering the resources assembled by the portal to users
almost anywhere, we believe this strategy can increase portal audiences and
enhance the value of the portal to our customers.

   Once our solution becomes an enterprise-wide Web platform, businesses can
use that platform as a delivery channel for new services, from conference room
scheduling to online procurement. By deploying hosted services through the
portal, customers accelerate time-to-benefit, increase the likelihood of a
successful deployment and take advantage of a typically large existing
audience. We believe the delivery of new services can generate additional
revenue opportunities with existing customers, and further differentiate our
offering with new customers.

 Build New Alliances with Technology Vendors and Systems Integrators

   We intend to continue to develop a broad base of systems integrator and
technology vendor alliances. Building these alliances allows our customers to
integrate a greater range of information and services and provides additional
support for portal deployments spanning a wide variety of technologies and
disciplines. Our alliances with systems integrators can create demand for our
product at integrators' clients around the world, and provide deployment
expertise that allows us to focus on generating software license revenue.

   Our alliances with technology vendors strengthen our brand and assure
prospective customers that our product can work with a wide range of best-of-
breed technologies. Many of these alliances have resulted in the development of
product extensions such as Plumtree Portal Gadgets, which can enhance our value
proposition to customers. As the number of customers grows, demand for gadgets
increases, providing alliance members with strong incentives to create
additional gadgets. This in turn generates more demand for our platform. We
have created a special business unit for recruiting alliance members and
customers to develop Plumtree Portal Gadgets that we can certify and distribute
to other customers.

 Increase Our Market Share Among Industry-Leading Customers

   We believe our leadership position as a provider of infrastructure software
for corporate portals can be attributed to our platform, which is designed to
integrate a wide range of applications and Internet-based services and to scale
to support hundreds of thousands of users. Large organizations, such as
Andersen Consulting LLC, Ford Motor Company, The Procter & Gamble Company and
Kmart Corporation, have chosen the Plumtree Corporate Portal. We intend to
leverage our reputation for working on large and complex assignments to assist
us in attracting new customers and alliance members and increasing our market
share.

 Capitalize on the Network Effect

   We believe our platform's open architecture, which allows customers and
alliance members to exchange information and services between portal
deployments, can be the basis for a network effect that can accelerate sales.
Each new deployment of our portal potentially contributes to the pool of
information and services on which prospective customers can draw. We intend to
target market-leading organizations in every industry and in government, as
hubs for sharing content and services with other organizations in that sector.
We believe this can drive additional sales to the customers and partners that
are receiving information and services from a hub account. To support this
strategy, we will continue to develop technologies for sharing information and
services between deployments, and will align our selling efforts to
systematically approach the organizations that work closely with our existing
customers.

Product

   Our solution consists of the Plumtree Corporate Portal and a wide range of
extensions to that product for integrating content and services from other
systems.

 Personalized Portal Page and Plumtree Portal Gadgets

   The personalized portal page is a Web page assembled by each portal user,
combining categories drawn from the portal's document directory with
information and services integrated from different systems as Plumtree Portal
Gadgets. Gadgets are plug-in components that communicate with an underlying
application or Internet service via a programming interface or the Web,
generating extensible mark-up language, or XML, or hypertext mark-up language,
or HTML. A user chooses the gadgets from which to build his or her page using
the Plumtree Corporate Portal. Our Massively Parallel Portal Engine, a feature
of version 4.0 of our portal, prepares the page, retrieving gadget data and
hosting interactive services from other systems.

   The gadgets now available with the Plumtree Corporate Portal are designed to
allow customers to deploy a portal that will provide access to their most
important systems rapidly, with little or no custom development. With a
separate Plumtree business unit dedicated to increasing the number of gadgets,
and a network of customers and partners developing gadgets that can be
certified and re-distributed, we believe the number of gadgets that will be
available to our customers will continue to grow.

 Plumtree Portal Communities

   Communities are similar to personalized portal pages, but are assembled by a
manager or project leader to communicate a group view of the business, and to
promote collaboration. Communities consist of gadgets and categories drawn from
the document directory, and also feature collaboration services for document
sharing, threaded conversation and assigning tasks to group members. A typical
portal deployment offers a wide variety of communities. Organizations can use
communities as business-to-employee resource centers, projecting a company-
wide, regional or departmental view of the business. Organizations can also use
communities as a business-to-business forum for collaborating with partners and
customers, or as an employee-to-employee working site for completing projects.
The portal enrolls new users in communities by supporting electronic mail
invitations that include a link for creating user accounts with pre-configured
profiles. The communities feature of our product is contained in version 4.0,
which is scheduled to be released in the fourth quarter of 2000.

 Plumtree Document Directory

   The document directory organizes links to a wide variety of documents from
different sources in a hierarchy of categories defined by each Plumtree
customer. This hierarchy is known as a taxonomy. Users search or browse this
taxonomy, and can also draw categories from the taxonomy to embed in a
personalized or community portal page, which highlights the most recent
documents available for that category.

   The directory indexes more than 15 types of documents, as well as Web pages,
database reports and electronic mail messages from Lotus Notes and Microsoft
Exchange. The portal stores only an index of the documents in the directory,
with links to their original location, avoiding content replication. To
identify new documents to index, our product automatically scans a wide variety
of document databases, file systems, Web sites and messaging databases. The
portal can be extended to scan new types of repositories using modular
components called Plumtree Crawlers, and to index documents in new formats
using modular components called Plumtree Accessors. These components operate on
a server separate from the Web server hosting the portal application, improving
reliability and performance.

   The document directory can be overseen by a large number of content experts
in different parts of an organization. These experts review the recommendations
of our categorization engine to determine if documents have been appropriately
indexed in the section of the taxonomy that they administer.

 Plumtree Portal Network Architecture

   The Plumtree Corporate Portal also offers a wide range of technologies for
distributing Plumtree Portal Gadgets assembled by the portal to other
businesses, platforms and devices. Because gadgets are hosted on separate
gadget servers and accessed via the open hyper-text transfer protocol, or HTTP,
multiple portal deployments can access a common gadget server, allowing
organizations to share interactive services with one another, or between
business units within a deployment.

   Using a technology known as gadget syndication, version 4.0 of our product
allows customers to distribute gadget content to other Web platforms from
vendors such as Interwoven or Vignette, and other devices such as standard
telephones or personal digital assistants. The same technology can also be used
to distribute information between businesses. For example, one company's portal
could distribute on a scheduled basis competitive news, an inventory report and
a calendar of events to a partner's intranet, freeing the partner from having
to visit that company's portal to stay up-to-date.

   The portal also features the ability to issue searches to other portals and
other systems, using the same technology that assembles gadget content from
multiple systems. This ability, known as networked search, allows a user of one
portal deployment to search another portal deployment in a different part of
one organization, or in a different organization that has agreed to share
information and services. Customers can plug-in new search components to
include search results from other systems, such as an Autonomy search index on
the corporate network, or a Google search index on the Internet. As a result, a
user of one portal deployment can, with a single search, retrieve results from
a wide range of systems.

Services

   In addition to offering infrastructure software, we offer customers and
alliance members a wide range of deployment and support services.

 Professional Services

   We offer professional services to deploy the Plumtree Corporate Portal at
customer sites, and to train alliance members, including technology vendors and
systems integrators. Our consultants are participating in joint deployments
with systems integrators, increasing our capacity to deploy at a large number
of customer sites.

 Customer Care Services

   We provide customer care through technical support and assigned account
managers. Technical support is offered for customers and alliance members
worldwide through our support centers in San Francisco and London. Standard
support is available via e-mail and telephone during normal business hours, and
premium support is available via telephone 24 hours per day, seven days per
week. Customers and alliance members may also receive technical support through
a portal community, which will be available with version 4.0 of our product. In
addition, local account managers provide customers with an advocate within
Plumtree to assist them in defining their business requirements and obtaining
the needed resources for a successful enterprise-wide deployment.

 Training Services

   We offer a series of training classes designed to provide our customers and
alliance members with the knowledge and tools necessary to deploy, administer
and expand the portal within the enterprise. Offered both at customer sites and
at training centers in various cities, these classes have, to date, enrolled
more than 350 individuals from customer and alliance member organizations.

Alliances

   We have developed relationships with a wide range of technology and systems
integrator alliance members. These relationships generate new sales
opportunities, increase our deployment capacity and fortify our platform with
new content and services.

 Technology Vendors

   Because a portal exists to integrate access to a wide range of technologies,
we seek to further establish our platform by cultivating extensive alliance
support. Several alliance members have participated in gadget development,
augmenting our ability to develop new portal extensions. We also market our
product through technology alliance members, participating in joint events and
engaging alliance member sales people to promote joint solutions. We have
relationships with over 25 technology alliance members:

Customer Profiles

   The selected customer examples below are intended to illustrate how our
customers are using, or planning to use, the Plumtree Corporate Portal to solve
their business needs.

 Ford Motor Company

   Ford Motor Company, the world's second largest automaker, has chosen our
product to power an enterprise-wide corporate portal for more than 200,000
employees worldwide. Ford is in the process of deploying the Plumtree Corporate
Portal as part of an initiative to modernize Ford's intranet, hub.ford.com, and
drive collaboration within business units. Ford will use our product to
consolidate the hundreds of intranet sites that comprise hub.ford.com to create
a manageable Web experience for the entire enterprise. Hub.ford.com will
integrate through the portal key capabilities of enterprise applications and
Internet services, and over one million documents stored worldwide, in a
single, searchable document directory. To assemble comprehensive views of their
business in personalized portal pages, Ford employees will be able to choose
from hub.ford.com's menu of Plumtree Portal Gadgets, which will include real-
time newsfeeds, stock reports, company directories, benefits information and
local weather. To facilitate project management and foster collaboration, Ford
is creating community pages that correspond to functional roles within the
company, such as purchasing, manufacturing and marketing. Our product's
architecture is designed to make it possible for hub.ford.com to generate
gadgets for employees under peak loads, which Ford estimates will be 10,000
hits per minute. The Plumtree Corporate Portal will synchronize with Ford's
existing directory of over 150,000 users, helping ensure that employees see the
content and services that correspond to their security profiles and specific
roles when they log in to hub.ford.com. We offer Ford a framework for
controlling an extensive network of intranets, and a platform for enterprise-
wide collaboration, with the scalability and security features it needs to
support its global employee base. In May 2000, Ford purchased 312,500 shares of
our Series E Preferred Stock.

 Procter & Gamble

   The Procter & Gamble Company, one of the world's largest consumer goods
marketers, is in the process of deploying the Plumtree Corporate Portal
throughout its global enterprise to give over 100,000 employees and partners a
single Web destination for the information, applications and services they need
to do their jobs. Procter & Gamble will use our product to enhance the
productivity of employees. In a searchable document directory, the Plumtree-
powered portal will aggregate content from more than one million Web pages and
thousands of Lotus Notes databases and file servers on Procter & Gamble's
global network. Procter & Gamble is integrating a range of enterprise
applications into the Plumtree Corporate Portal as Plumtree Portal Gadgets,
including services from the company's SAP R/3 enterprise resource planning
system, Oracle data warehousing and business intelligence applications and
E.piphany E4 analytic customer relationship management system. Procter & Gamble
employees will be able to choose from a menu of gadgets to assemble a
comprehensive view of their business in personalized portal pages. For example,
an employee might embed an Oracle gadget for analyzing sales histories and an
SAP gadget for approving purchase orders in a MyPage alongside an e-mail inbox
and market news and product notices from the document directory. Procter &
Gamble will use our product to offer employees a single, simple point of access
to the applications and services they need to assess revenue opportunities,
shorten lead times on sales and collaborate more effectively. In May 2000,
Procter & Gamble purchased 208,333 shares of our Series E Preferred Stock.
Procter & Gamble also holds a warrant to purchase 100,000 shares of our common
stock.

 webMethods

   webMethods, Inc., a provider of software solutions for business-to-business
integration, implemented the Plumtree Corporate Portal enterprise-wide to
provide each of its employees with a single portal to the information and
services they need to get their jobs done, whether in the office or in the
field. In addition, webMethods uses our product to help orient new employees to
the company quickly and keep them up to speed. Within a month of the decision
to deploy our product, webMethods rolled out the Plumtree-powered
mywebMethods.com, which brings together content dispersed throughout the
company intranet and a broad range of Internet services in a simple Web
experience for all webMethods' employees. Over 75 enterprise applications and
services have been integrated into mywebMethods.com as Plumtree Portal Gadgets,
including key capabilities of the company's Siebel customer relationship
management system, its Open Text Livelink document management system, calendar
and scheduling tools from CorporateTime and expense reporting services from
ExpensAble.com. From the portal, a webMethods sales representative can embed
Siebel gadgets for managing accounts, contacts, activities and sales
opportunities alongside an e-mail inbox gadget, a news-feed gadget and product
updates from the document directory. The portal preferences of new employees
are created according to their roles within the company to ensure that the
specific information and services they need to do their jobs begins to funnel
to their desktop the first time they log on. We are helping webMethods mobilize
the entire enterprise for growth with a gateway to the content and services
employees need to support customers, capitalize on sales opportunities and
cultivate new revenue channels.

 California Casualty Management Company

   California Casualty Management Company, a provider of group automobile and
home insurance for over 100 associations in 16 states, uses the Plumtree
Corporate Portal to give its policyholders personalized access to their
accounts online. When hundreds of the customers surveyed by California Casualty
requested the convenience of managing their accounts over the Web, the company
chose us to provide the infrastructure for MyAPlus.com, a secure self-service
portal for California Casualty's 165,000 policyholders. The integration of the
Plumtree Corporate Portal with the company's mainframe legacy insurance
applications allowed California Casualty to put billing and policy information
online within two months of deploying a corporate portal. California Casualty
customers can now assemble a complete, personalized view of their accounts on
the Web. A policyholder can embed Plumtree Portal Gadgets in his or her MyPage
to view billing or policy information, make a payment by credit card, request a
policy change or file a claim. The Plumtree-powered MyAPlus.com also features a
searchable directory of insurance concepts and terms. By December 31, 2000,
California

                                       40
<PAGE>

Casualty expects to be able to present a policyholder's actual policies in .pdf
format from newly structured electronic policy archives via the Plumtree
Corporate Portal, and it also expects to deliver insurance quotes in real time
to both prospects and customers from their MyAPlus.com pages. The use of our
product by California Casualty cuts phoning, faxing, e-mailing and mailing
costs, and has the potential to increase customer acquisition and retention for
California Casualty.

Sales and Marketing

   We pursue accounts using our direct sales force and through systems
integrators and independent software vendors. We focus our sales activities on
large businesses and government organizations, particularly market-leading
organizations in each industry, as hubs for distributing content and services
to other prospective accounts in that industry.

   As of June 30, 2000, our direct sales organization consisted of 77 managers,
account executives, product consultants and business development professionals,
divided into five regional teams. We have sales representatives throughout the
United States and Europe, located in major cities such as Boston, New York,
Washington D.C., Atlanta, Chicago, Cincinnati, Minneapolis, Denver, Los
Angeles, Seattle, London and San Francisco.

   Our marketing efforts are conducted by a marketing organization and product
management team, which, as of June 30, 2000, consisted of 25 professionals. The
marketing organization is generally responsible for product positioning,
product direction, communications, field events, sales tools, competitive
analysis and alliance marketing. The product management team drives product
direction, technical marketing and competitive analysis. We generate sales
leads from our communications programs that include our Web site, public
relations, on-line and local seminars, tradeshows and events. The alliance
marketing efforts are designed to support co-marketing programs with our
alliance members.

Technology

   The Plumtree Corporate Portal is based on three core technologies.

 Extensible Portal Server

   Our product integrates a wide range of information and services from other
systems. Our architecture is extensible, which empowers customers and partners
to develop plug-in components to integrate new types of content and new types
of services, maximizing the resources available to users through the portal.
The Plumtree Corporate Portal is extensible in five ways:

  . Content: Plug-in modules called Plumtree Portal Accessors integrate
    different types of content from different types of repositories in
    Plumtree's document directory.

  . Services: Plug-in modules called Plumtree Portal Gadgets integrate
    application and Internet services in the portal's personalized and
    community pages.

  . Security: Plug-in modules called Plumtree Authentication Providers
    synchronize users' security profiles from other systems, allowing the
    portal to negotiate access to the wide range of secure resources
    available to each user through different profiles.

  . Search: Plug-in modules called Plumtree Search Providers open different
    search indexes to the portal's search capability, empowering users to
    search simultaneously the repositories indexed in the Plumtree portal as
    well as other indexes maintained by other search engines on the Internet
    and the corporate network.

  . Media: Plug-in modules called Plumtree Transformers syndicate the content
    assembled in the portal for distribution to other platforms and other
    devices, including wireless devices and telephones.

                                       41
<PAGE>

 Massively Parallel Portal Engine

   To scale to meet the needs of a large number of users with many gadgets in a
personalized, secure way, we have developed the Massively Parallel Portal
Engine, which sends requests to multiple gadget servers in parallel through
HTTP. Our engine is designed to retrieve content and services from a large
number of Web servers, using separate threads to retrieve each service in
parallel, and optimizing the number of network sockets opened to communicate
with those servers. This approach is more scalable because it divides the
preparation of a potentially large number of services among a large number of
computers. If, for example, a portal page embeds a gadget for listing e-mail
messages that takes one second to prepare, an inventory report gadget that
takes one second to prepare and an industry news gadget that takes one second
to prepare, the Massively Parallel Portal Engine assembles the page in
approximately one second, instead of three. This approach is also designed to
be fault-tolerant, as gadgets operating on separate computers cannot interfere
with one another or with the portal's main Web server.

 Open Network

   Because HTTP does not support intricate, continuous communications between
application components, we have developed an approach for embedding complex
configuration commands within the prefix section of an HTTP communication,
known as HTTP headers. By operating within the parameters of the HTTP standard,
this technology opens our portal infrastructure to integrate a wide range of
components, and allows our infrastructure to harness the power of multiple
computers connected over the Internet.

   As a result, portal deployments can integrate services from any server
within an organization, or by connecting to a server on the Internet. Customers
that previously hosted gadgets within their own organization can now integrate
new services in the portal by connecting to gadget servers on the Internet,
hosted by partners, application solution providers and other customers. This
technology also allows portal deployments to connect to a common gadget server
via the Internet, sharing services between deployments.

Research and Development

   Since inception, we have devoted significant resources to develop our
product and technology. We believe our future success depends in large part on
continuing innovation and rapid development. Our engineering organization is
responsible for product architecture and technology, engineering and quality
assurance. As of June 30, 2000, our engineering organization consisted of 40
employees. The team is organized in groups focused on server architecture, user
interface design and implementation, extensibility architecture,
internationalization, UNIX development, gadget development and quality
assurance. For the year ended December 31, 1999, our research and development
expenses totaled approximately $1.7 million. For the six months ended June 30,
2000, research and development expenses totaled approximately $1.9 million. We
expect to continue to devote substantial resources to our research and
development activities.

Intellectual Property and Licensing

   Our success and ability to compete is dependent in part on our ability to
develop and maintain the proprietary aspects of our technology and operate
without infringing the proprietary rights of others. We rely primarily on a
combination of copyright, trade secret and trademark laws, confidentiality
procedures, contractual provisions and other similar measures to protect our
proprietary information. For example, we license rather than sell our software
to customers and require licensees to enter into license agreements that impose
certain restrictions on their ability to utilize the software. We have filed
one provisional patent application with the U.S. Patent and Trademark Office.
There can be no assurance that any of our intellectual property rights will not
be challenged or invalidated.

                                       42
<PAGE>

   We also enter into license agreements with respect to our technology,
documentation and other proprietary information. Those licenses are generally
non-transferable and typically have a perpetual term. Despite our efforts to
protect our proprietary rights, unauthorized parties may attempt to copy,
reverse engineer or otherwise obtain and use our products or technology that we
consider proprietary, and third parties may attempt to develop similar
technology independently. Policing unauthorized use of our products is
difficult, particularly because the global nature of the Internet makes it
difficult to control the ultimate destination and security of software and
other data transmitted.

   We integrate third-party software into our products. This third-party
software may not continue to be available on commercially reasonable terms. We
currently license our search engine, which is integrated into the Plumtree
Corporate Portal, from Verity, Inc. This technology provides users with the
ability to search and classify information. If we fail to maintain licenses to
this and other third-party software, shipments of our products could be delayed
until equivalent software could be developed or licensed and integrated into
our products, which could seriously harm our business, operating results and
financial condition.

   We do not believe that any of our products infringe the proprietary rights
of third parties. However, third parties may assert infringement claims against
us in the future with respect to current or future products. Further, we expect
that software product developers will increasingly be subject to infringement
claims as the number of products and competitors in our industry segment grows
and the functionality of products in different industry segments overlaps. Any
claims of that variety, with or without merit, could cause a significant
diversion of management attention, result in costly and protracted litigation,
cause product shipment delays or require us to enter into royalty or licensing
agreements. Those royalty or licensing agreements, if required, may not be
available on terms acceptable to us or at all, which could seriously harm our
business.

   Our policy is to require all of our employees to sign nondisclosure and
confidentiality agreements. From time to time, we hire or retain employees or
consultants who have worked for independent software vendors or other companies
developing products similar to those offered by us. Those prior employers may
claim that our products are based on their products and that we have
misappropriated their intellectual property. Any claims of that variety, with
or without merit, could cause a significant diversion of management attention,
result in costly and protracted litigation, cause product shipment delays or
require us to enter into royalty or licensing agreements. Those royalty or
licensing agreements, if required, may not be available on terms acceptable to
us or at all, which could harm our business.

Competition

   The market for our product is intensely competitive and highly fragmented,
characterized by rapid technological change, evolving industry standards and
changes in customer needs, and new product introductions and improvements. Our
current competitors include established software vendors that are Web-enabling
their applications or are building infrastructure software, emerging companies
offering competitive products and companies choosing to build their own
solutions.

   Some established software vendors are Web-enabling traditional client-server
applications, which in some cases are being labeled as portal applications.
Prospective customers who require only a Web view of their applications may not
need a corporate portal product and may be satisfied with this category of
products. Some established software vendors in the operating system business,
database business or application server business are offering portal-building
tools. These companies support a build-your-own alternative to our product.
Since many prospects already license other software from these vendors, a
customer-vendor relationship already exists between them. We face competition
from internal information technology departments of potential customers that
have developed or may develop in-house technologies that may substitute for
those offered by us. We expect these internal development initiatives will
continue to be a source of competition. We also face competition from emerging
software companies. These companies generally offer products that could
substitute for those offered by us.


                                       43
<PAGE>

   We expect to face increased competition in the future from our current
competitors. In addition, new competitors, or alliances among existing and
future competitors, may emerge and rapidly gain significant market share. Many
of our competitors have longer operating histories, significantly greater
financial, technical, marketing and other resources, greater name recognition,
a broader range of products to offer and a larger installed customer base, any
of which could provide them with a significant competitive advantage. We expect
that the rapid evolution of Internet-based software applications and standards
will require us to adapt our software products to remain competitive. If we are
unable to compete successfully, we may be unable to attract and retain
customers. Increased competition could also result in price reductions for our
products and lower profit margins, either of which could harm our business,
results of operations and financial condition.

   We compete principally on the basis of:

  . product features, quality and performance;

  . interoperability of the product with existing applications;

  . number, size and satisfaction of customers;

  . number and significance of alliances; and

  . strength of sales and services channels.

   We may be unable to successfully compete against current and future
competitors, and competitive pressures we face may harm our business,
prospects, operating results and financial condition.

Employees

   As of June 30, 2000 we had 152 full-time employees, of whom 151 were based
in North America and one was based in Europe. Of those employees, 57 were in
sales and marketing, 40 were in product development, 45 were in professional
services, technical support and training, and 10 were in finance, human
resources, information systems and administrative functions. Our employees are
not represented by any collective bargaining agreements and we have never
experienced a work stoppage.

Facilities

   Our principal headquarters facility is located in approximately 32,000
square feet of office space in San Francisco, California under a lease that
expires in 2006. We house additional headquarters employees in a separate San
Francisco facility with approximately 5,600 square feet of office space, under
a lease that expires in April 2001. We are seeking additional space in Northern
California to meet our expansion plans.

                       Option Grants In Last Fiscal Year

   The following table provides information concerning grants of options to
purchase our common stock made during the fiscal year ended December 31, 1999
to the Named Executive Officers.

   In the fiscal year ended December 31, 1999, we granted options to purchase
up to an aggregate of 1,894,566 shares to employees, directors and consultants.
All options were granted under our 1997 equity incentive plan at exercise
prices at 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. Generally, option shares 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 for the next 36 months.

   The potential realizable values are based on an assumption that the price of
our common stock will appreciate at the compounded annual rate shown from the
date of grant until the end of the option term. These values do not take into
account amounts required to be paid as income taxes under the Internal Revenue
Code and any applicable state laws or option provisions providing for
termination of an option following termination of employment, non-
transferability or vesting. These amounts are calculated based on the
requirements promulgated by the Securities and Exchange Commission and do not
reflect our estimate of future stock price growth of the shares of our common
stock.

exercise price, multiplied by the number of shares issued upon exercise of the
option. All options were granted under our 1997 Equity Incentive Plan.

1997 Equity Incentive Plan

   The 1997 equity incentive plan was adopted by our board of directors on June
30, 1997 and approved by our stockholders on the same date for the benefit of
our officers, directors and consultants. This plan has been amended, most
recently on July 19, 2000 to approve an additional 2,000,000 shares of common
stock for issuance under this plan, and this amendment was approved by our
stockholders. This plan provides for the grant of incentive stock options and
nonstatutory stock options. An aggregate of 11,970,000 shares of common stock
is reserved for issuance under this plan. As of August 31, 2000, an aggregate
of 4,948,630 shares of common stock were outstanding under this plan. We will
not be granting options under this plan following the offering.

   In the event of certain mergers or consolidations of Plumtree, outstanding
options will be assumed or similar options substituted. In the event
outstanding options are not assumed or substituted for, these options will
terminate if not exercised before the event. In the event of a dissolution or
liquidation of Plumtree, outstanding options will terminate if not exercised
before these events.

2000 Stock Incentive Plan

   On September 7, 2000, subject to the approval of the stockholders, our board
of directors adopted the Plumtree 2000 Stock Incentive Plan, or 2000 Plan, for
the benefit of officers, directors, key employees, advisors and consultants of
Plumtree and its subsidiaries (including directors who are employees) and
reserved for issuance thereunder 10 million shares of common stock initially,
with an annual increase in shares of common stock reserved for issuance equal
to the lesser of (i) 1 million shares or (ii) 1% of the number of outstanding
shares of common stock on the last trading day of the immediately preceding
fiscal year. The 2000 Plan is scheduled to take effect upon the consummation of
the initial public offering. The 2000 Plan provides for the issuance of stock-
based incentive awards, including stock options, restricted stock, restricted
stock units, dividend equivalents and other stock-based awards. An award may
consist of one arrangement or benefit or two or more of them in tandem or in
the alternative. Under the 2000 Plan, awards covering no more than      of the
shares reserved for issuance under the plan may be granted to any participant
in any one year.

   The 2000 Plan will be administered by our board of directors, or a
specifically designated committee of the board. The committee has the
discretionary authority to interpret the 2000 Plan and may prescribe, amend or
rescind rules and make all other determinations necessary or desirable for the
administration of the 2000 Plan. The 2000 Plan permits the committee to select
the officers, directors, key employees, advisors and consultants of Plumtree
and its subsidiaries (including directors) who are also employees who will
receive awards and generally to determine the terms and conditions of those
awards.

   In the event of a merger, consolidation, reorganization, recapitalization,
stock dividend or other change in corporate structure affecting the number of
issued shares of common stock, the committee may make an equitable substitution
or proportionate adjustment in the number and type of shares authorized by this
plan, the number and type of shares covered by, or with respect to which
payments are measured under, outstanding awards and the exercise prices.

   The terms of this plan provide that the committee may amend, suspend or
terminate the 2000 Plan at any time, provided, however, that some amendments
may require approval of the shareholders. Further, no action may be taken which
adversely affects any rights under outstanding awards without the holder's
consent.

   Under the 2000 Plan, upon election to the Board (or on the effective date of
the 2000 Plan if already a non-employee director), each non-employee director
will receive a grant of options to purchase 50,000 shares of common stock at an
exercise price per share equal to the fair market value of a share of common
stock on the date of grant. In addition, each non-employee director will
automatically receive an annual grant of options to purchase 20,000 shares of
common stock at a per share exercise price equal to the fair market value of a
share of common stock on the date of grant immediately following Plumtree's
annual meeting of shareholders

                                       49
<PAGE>

each year during the director's term. Each such option shall be fully vested
and exercisable upon the first anniversary of the date of grant and shall have
a five (5) year term.

   Plumtree may issue two types of stock options under the 2000 Plan: incentive
stock options, or ISOs, which are intended to qualify as such under the
Internal Revenue Code of 1986, as amended, and non-qualified stock options, or
NSOs. The committee will determine the exercise price, vesting period and
performance goals, if any, with respect to grants of stock options. The
exercise price of each ISO granted under this plan must be at least equal to
the fair market value of a share of common stock on the date the ISO is
granted.

   Awards of restricted stock and restricted stock units may be granted under
the 2000 Plan. The committee will determine the purchase price, performance
period and performance goals, if any, with respect to grants of restricted
stock or restricted stock units. If the performance goals and other
restrictions are not attained, the participant will forfeit his or her shares
of restricted stock or restricted stock units. Participants with restricted
stock generally have all of the rights of a stockholder.

   Dividend equivalents may also be issued under the 2000 Plan. Dividend
equivalents provide for the payment of stock, cash or other property equal in
value to dividends paid with respect to a specified number of shares.

   The committee, in its discretion, may also grant other equity-based awards.

2000 Employee Stock Purchase Plan

   The 2000 Employee Stock Purchase Plan, or Purchase Plan, is designed to
allow eligible employees to purchase Plumtree's common stock at a discount from
fair market value. On September 7, 2000, subject to the approval of the
stockholders, the board adopted the Purchase Plan and reserved for issuance
thereunder a total of 1,000,000 shares of common stock for each fiscal year
occurring during the term of the Purchase Plan. The Purchase Plan is scheduled
to take effect upon the consummation of the initial public offering.

   The Purchase Plan will be administered by the compensation committee of the
board of directors or a specifically designated committee of the board (the
committee being referred to as the "Plan Administrator"). The Purchase Plan
Administrator has the discretionary authority to interpret the Purchase Plan
and, subject to its provisions, may prescribe, amend and rescind rules and make
all other determinations necessary or desirable for the administration of the
Purchase Plan.

   The Purchase Plan contains offering periods that commence on the first
trading day on or after April 1 and October 1 of each year and end on the last
trading day before the commencement of the next offering period; provided,
however, that the first offering period under the plan will commence upon the
consummation of the initial public offering and end on the last trading day on
or before September 30, 2002. Subsequent offering periods shall be six months
in length beginning each April 1 and October 1 of each year. Stock purchases
are made at the end of each purchase period. Purchase periods are six months in
length beginning each April 1 and October 1 of each year; provided, however,
that the first purchase period under the plan will commence upon the
consummation of the initial public offering and end on the last trading day on
or before March 31, 2001.

   Employees are eligible to participate if they have been employed by Plumtree
or any participating subsidiary for at least one year and customarily work at
least 20 hours per week. However, an employee may not be granted the right to
purchase stock under the Purchase Plan if the employee (i) immediately after
the grant would own stock possessing 5% or more of the total combined voting
power or value of all classes of Plumtree's capital stock, or (ii) holds rights
to purchase stock under any of our employee stock purchase plans that together
accrue at a rate which exceeds $25,000 worth of stock for each calendar year.
The Purchase Plan permits each employee to purchase common stock through
payroll deductions of up to 15% of the employee's "compensation." Compensation
is defined as the employee's base salary, wages, commissions, overtime pay and
bonuses paid to an employee. The maximum number of shares an employee may
purchase during a single offering period is 500 shares.

                                       50
<PAGE>

   Amounts deducted and accumulated by the employee are used to purchase shares
of common stock at the end of each offering period. The price of the common
stock offered under this plan is an amount equal to 85% of the lower of fair
market value of the common stock at (i) the beginning of the offering period or
(ii) the end of the purchase period. Employees may end their participation in
the Purchase Plan at any time during an offering period, in which event, any
amounts withheld through payroll deductions and not otherwise used to purchase
shares will be returned to them. Participation ends automatically upon
termination of employment with Plumtree or any participating subsidiary.

   Rights granted under the Purchase Plan are not transferable by any employee
other than by will or the laws of descent and distribution. The Purchase Plan
provides that, in the event of a merger, consolidation, reorganization,
recapitalization, stock dividend or other change in corporate structure
affecting the number of issued shares of Plumtree's stock, the Plan
Administrator will conclusively determine the appropriate equitable
adjustments. The Purchase Plan will terminate ten years after it becomes
effective. Plumtree's board has authority to amend or terminate the Purchase
Plan, except that no amendment or termination may adversely affect any
outstanding rights under the Purchase Plan.

Employment Agreements

   We have offer letters with Mr. Kunze, Mr. Hogan, Mr. Flatley, and Mr.
Borrmann. Each of these officers may leave or be terminated at any time. Each
of these offer letters, with the exception of Mr. Hogan's letter, provides that
if the executive's employment is terminated by us without cause within the
first year of employment, the executive will receive 12 months of base salary
continuation, or, if so terminated following the first year of employment, six
months of base salary continuation. Generally, cause means a willful act or
omission involving material injury to Plumtree, gross misconduct or fraud,
willful disobedience of reasonable directives of the board of directors, or
conviction of a felony. In the event of an acquisition of Plumtree or the sale
of all or substantially all of the assets of Plumtree, 50% of the executive's
then unvested shares subject to stock options vest immediately, except that, in
the case of Mr. Hogan, all such unvested shares vest.

   Under the applicable offer letter, Mr. Kunze is entitled to an annual salary
of $200,000 and is eligible for a potential bonus of $100,000; Mr. Hogan is
entitled to an annual salary of $150,000; Mr. Flatley is entitled to an annual
salary of $200,000 and is eligible for a potential bonus of $200,000; and Mr.
Borrmann is entitled to an annual salary of $180,000 and is eligible for a
potential bonus of $40,000. Payment of bonuses is dependent on the attainment
of objectives established by our board of directors.

Loans to Executive Officers

   In August 2000, we loaned $520,000 to Eric Borrmann, our Chief Financial
Officer, in conjunction with the exercise of an option. The note evidencing
this indebtedness is a full recourse promissory note and is secured by a pledge
agreement. The note accrues interest at the rate of 6% per year and is payable
upon demand.

Limitation of Liability and Indemnification

   Upon the closing of this offering, our certificate of incorporation will
include a provision that eliminates the personal liability of our directors for
monetary damages for breach of fiduciary duty as a director, except for
liability:

  . for any breach of the director's duty of loyalty to us or our
    stockholders;

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

  . under Section 174 of the Delaware General Corporation Law; or

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

                                       51
<PAGE>

   Our certificate of incorporation and bylaws will further provide for the
indemnification of our directors and officers to the fullest extent permitted
by Section 145 of the Delaware General Corporation Law, including circumstances
in which indemnification is otherwise discretionary. Insofar as indemnification
for liabilities arising under the Securities Act may be permitted to directors,
officers and controlling persons of Plumtree under the foregoing provisions, or
otherwise, we have been advised that in the opinion of the Securities and
Exchange Commission this indemnification is against public policy as expressed
in the Securities Act and is, therefore, unenforceable.

   We intend to enter into agreements to indemnify our directors and executive
officers, in addition to indemnification provided for in our bylaws. These
agreements, among other things, will 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
the 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.

                             PRINCIPAL STOCKHOLDERS

   The following table indicates information as of August 31, 2000 regarding
the beneficial ownership of our common stock by:

  . each person known to the board of directors to own beneficially 5% or
    more of our common stock;

  . each of our directors;

  . the Named Executive Officers; and

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

   Information with respect to beneficial ownership has been furnished by each
director, officer or 5% or more stockholder, as the case may be. Except as
otherwise noted below, the address for each person listed on the table is c/o
Plumtree Software, Inc., 500 Sansome Street, San Francisco, California 94111.

   Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission which generally attribute beneficial
ownership of securities to persons who possess sole or shared voting power or
investment power with respect to those securities and includes shares of common
stock issuable pursuant to the exercise of stock options or warrants that are
immediately exercisable or exercisable within 60 days. Unless otherwise
indicated, the persons or entities identified in this table have sole voting
and investment power with respect to all shares shown as beneficially owned by
them, subject to applicable community property laws.

   Percentage ownership calculations are based on 23,840,538 shares of common
stock outstanding as of August 31, 2000, which number includes shares of common
stock that will be outstanding upon the conversion of outstanding shares of
preferred stock upon the closing of the offering. To the extent that any shares
are issued upon exercise of options, warrants or other rights to acquire our
capital stock that are presently outstanding or granted in the future or
reserved for future issuance under our stock plans, there will be further
dilution to new public investors.

                         DESCRIPTION OF CAPITAL STOCK

   Upon the closing of this offering, we will be authorized to issue
100,000,000 shares of common stock, $0.001 par value per share, and 10,000,000
shares of preferred stock, $0.001 par value per share. The following
description summarizes information regarding our capital stock and assumes our
reincorporation in Delaware before the closing of this offering. This
information does not purport to be complete and is subject in all respects to
the applicable provisions of the Delaware General Corporation Law, our
certificate of incorporation and our bylaws.

Common Stock

   Each share of common stock entitles the holder to one vote on all matters
submitted to a vote of stockholders, including the election of directors.
Holders of common stock are entitled to receive ratably the dividends, if any,
declared from time to time by the board of directors out of legally available
funds. See "Dividend Policy." Holders of common stock have no conversion,
redemption or preemptive rights to subscribe to any of Plumtree's securities.
In the event of any liquidation, dissolution or winding-up of our affairs,
holders of common stock will be entitled to share ratably in our assets
remaining after provision for payment of liabilities to creditors. The rights,
preferences and privileges of holders of common stock are subject to the
rights of the holders of any shares of preferred stock which we may issue in
the future.

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. We cannot predict the 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 the preferred stock. However, the effects could include one
or more of the following:

  . 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 us without further action
    by the stockholders.

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

Warrants

   As of August 31, 2000, we had the following warrants to purchase shares of
common stock outstanding:

  . Lighthouse Capital Partners III, L.P. holds a warrant to purchase 11,250
    shares at an exercise price of $2.00 per share;

  . Procter & Gamble holds a warrant to purchase 100,000 shares at an
    exercise price of $2.00 per share; and

  . WXI/SAN Realty, L.L.C. holds warrants to purchase an aggregate of 41,030
    shares at an exercise price of $9.60 per share.

   As of August 31, 2000, we had the following warrants to purchase shares of
preferred stock outstanding:

  . Lighthouse Capital Partners II, L.P. holds a warrant to purchase 36,206
    shares of Series A preferred stock at an exercise price of $0.39 per
    share;

                                      56
<PAGE>

  . Silicon Valley Bank holds a warrant to purchase 28,125 shares of Series C
    preferred stock at an exercise price of $0.87 per share;

  . Silicon Valley Bank holds a warrant to purchase 138,462 shares of Series
    D preferred stock at an exercise price of $0.87; and

  . Lighthouse Capital Partners III, L.P. holds a warrant to purchase 9,375
    shares of Series D preferred stock at an exercise price of $1.60.

  All of the warrants listed above are currently exercisable and contain
standard anti-dilution provisions.

Registration Rights

   Upon completion of this offering, the holders of an aggregate of
shares of common stock issuable upon conversion of preferred stock and upon the
exercise of warrants will be entitled to rights with respect to the
registration of these shares under the Securities Act of 1933, as amended, or
the Securities Act. Under the terms of the registration rights agreements, if
Plumtree proposes to register any of its securities under the Securities Act,
either for its own account or for the account of other security holders
exercising registration rights, these holders are entitled to notice of this
registration and are entitled to include shares of common stock in the
registration. The rights are subject to conditions and limitations, among them
the right of the underwriters of an offering subject to the registration to
limit the number of shares included in the registration. These registration
rights have been waived with respect to this offering. Holders of these rights
may also require Plumtree to file a registration statement under the Securities
Act of 1933, as amended, at its expense with respect to their shares of common
stock, and Plumtree is required to use its best efforts to effect this
registration, subject to conditions and limitations. Furthermore, stockholders
with registration rights may require Plumtree to file additional registration
statements on Form S-3, subject to conditions and limitations.

Delaware Anti-Takeover Law

   Upon the closing of this offering, we will be subject to Section 203 of the
Delaware General Corporation Law, an anti-takeover law. Generally, Section 203
of the Delaware General Corporation Law prohibits a publicly held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years after the date of the transaction in
which the person became an interested stockholder, unless (i) before the date
of the business combination, the transaction is approved by the board of
directors of the corporation, (ii) upon consummation of the transaction which
resulted in the stockholder becoming an interested stockholder, the interested
stockholder owns at least 85% of the outstanding stock, or (iii) on or after
the date the business combination is approved by the board and by the
affirmative vote of at least 66 2/3% of the outstanding voting stock which is
not owned by the interested stockholder. A "business combination" includes
mergers, asset sales and other transactions resulting in a financial benefit to
the stockholder. An "interested stockholder" is a person who, together with
affiliates and associates, owns (or within three years, did own) 15% or more of
the corporation's voting stock. The existence of this provision would be
expected to have an anti-takeover effect with respect to transactions not
approved in advance by our 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.

Transfer Agent and Registrar

              will serve as Transfer Agent and Registrar for our common stock.

Listing

   We have applied to have our common stock approved for listing on The Nasdaq
Stock Market's National Market under the symbol PLUM.

                        SHARES ELIGIBLE FOR FUTURE SALE

   We cannot predict if future sales of our common stock, or the availability
of our common stock for sale, will depress the market price for our common
stock or our ability to raise capital by offering equity securities. Sales of
substantial amounts of common stock, or the perception that these sales could
occur, may depress prevailing market prices for the common stock.

   After this offering, approximately          shares of common stock will be
outstanding. All of the shares sold in this offering will be freely tradable
except for any shares purchased by affiliates of Plumtree. The remaining shares
of common stock outstanding after this offering will be restricted as a result
of securities laws or lock-up agreements. These remaining shares will be
available for sale in the public market as follows:

"Underwriting" and "Shares Eligible for Future Sale."

   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 would be entitled to sell within any three-
month period a number of shares that does not exceed the greater of:

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

  . the average weekly trading volume of the common stock on the Nasdaq
    National Market during the four calendar weeks preceding the filing of a
    notice on Form 144 with respect to the sale.

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

   Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the 90 days preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an affiliate, 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, as currently in effect, permits resales of shares in reliance upon
Rule 144 but without compliance with certain restrictions, including the
holding period requirement, of Rule 144. Any of our employees, officers,
directors or consultants who purchased shares under a written compensatory plan
or contract may be entitled to rely on the resale provisions of Rule 701. Rule
701 permits affiliates to sell their Rule 701 shares under Rule 144 without
complying with the holding period requirements of Rule 144. Rule 701 further
provides that non-affiliates may sell their shares in reliance on Rule 144
without having to comply with the holding period, public information, volume
limitation or notice provisions of Rule 144. All holders of Rule 701 shares are
required to wait until 90 days after the date of this prospectus before selling
their shares. However, substantially all Rule 701 shares are subject to lock-up
agreements and will only become eligible for sale at the earlier of the
expiration of the 180-day lock-up agreements or no sooner than 90 days after
the offering upon obtaining the prior written consent of Credit Suisse First
Boston Corporation.

   We intend to file a Registration Statement on Form S-8 registering shares of
common stock subject to outstanding options or reserved for future issuance
under our stock plans. As of August 31, 2000, options to purchase a total
4,948,630 shares were outstanding under our stock plans. Common stock issued
upon exercise of outstanding vested options, other than common stock issued to
our affiliates, is available for immediate resale in the open market.

   Under the terms and subject to the conditions contained in an underwriting

Dain Rauscher 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 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 may be terminated.

   We have granted to the underwriters a 30-day option to purchase on a pro
rata basis up to          additional shares at the initial public offering
price less the underwriting discounts and commissions. The option may be
exercised only to cover any 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 selling 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 broker/dealers may be changed by
the representatives.

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

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

   We have agreed that we will not offer, sell, contract to sell, pledge or
otherwise dispose of, directly or indirectly, or file with the Securities and
Exchange Commission a registration statement under the Securities Act of 1933
relating to, any shares of our common stock or securities convertible into or
exchangeable or exercisable for any shares of our common stock, or publicly
disclose the intention to make any such offer, sale, pledge, disposition or
filing, without the prior written consent of Credit Suisse First Boston
Corporation for a period of 180 days after the date of this prospectus, except
issuances pursuant to the exercise of employee stock options outstanding on the
date hereof.

   Our officers, directors and substantially all of our existing stockholders
have agreed that they will not offer, sell, contract to sell, pledge or
otherwise dispose of, directly or indirectly, any shares of our common stock or
securities convertible into or exchangeable or exercisable for any shares of
our common stock, enter into a transaction which would have the same effect, or
enter into any swap, hedge or other arrangement that transfers, in whole or in
part, any of the economic consequences of ownership of our common stock,
whether

                                       59
<PAGE>

any of these transactions are to be settled by delivery of our common stock or
other securities, in cash or otherwise, or publicly disclose the intention to
make any offer, sale, pledge or disposition, or to enter into any transaction,
swap, hedge or other arrangement, without, in each case, 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 public offering
price, up to        shares of the common stock for employees, directors and
other persons associated with us who have expressed an interest in purchasing
common stock in the offering. The number of shares available for sale to the
general public in the offering will be reduced to the extent these persons
purchase the reserved shares. Any 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 contribute to payments which the underwriters may be
required to make in that respect.

   We have applied to list the shares of common stock on The Nasdaq Stock
Market's National Market under the symbol PLUM.

   Credit Suisse First Boston Corporation acted as placement agent in
connection with the sale of the Series E Preferred Stock for which it received
customary compensation. Credit Suisse First Boston Venture Fund I, L.P. and
Credit Suisse First Boston Venture Fund II, L.P. have purchased 87,500 and
37,500 shares of Series E Preferred Stock, respectively, at $9.60 per share.
Under the NASD's Rules of Fair Practice, the difference between the initial
public offering price of our common stock and the purchase price could be
deemed underwriting compensation.

   Prior to this offering, there has been no public market for our common
stock. The initial public offering price has been determined by negotiation
between us and the representatives. The principal factors considered in
determining the public offering price include the following:

  . The information included in this prospectus and otherwise available to
    the representatives;

  . The market conditions for initial public offerings;

  . The history and prospects for the industry in which we will compete;

  . The ability of our management;

  . The present state of our development and our current financial condition;

  . The general condition of the securities markets at the time of this
    offering; and

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

   In connection with the offering the underwriters may engage in stabilizing
transactions, over-allotment transactions, syndicate covering transactions and
penalty bids in accordance with Regulation M under the Securities Exchange Act
of 1934.

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

  . Over-allotment involves sales by the underwriters of shares in excess of
    the number of shares the underwriters are obligated to purchase, which
    creates a syndicate short position. The short position may be either a
    covered short position or a naked short position. In a covered short
    position, the number of shares over-allotted by the underwriters is not
    greater than the number of shares that they may purchase in the over-
    allotment option. In a naked short position, the number of shares
    involved is greater than the number of shares in the over-allotment
    option. The underwriters may close out any short position by either
    exercising their over-allotment option and/or purchasing shares in the
    open market.

  . 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. In determining the source of

                                       60
<PAGE>

    shares to close out the short position, the underwriters will consider,
    among other things, the price of shares available for purchase in the open
    market as compared to the price at which they may purchase shares through
    the over-allotment option. If the underwriters sell more shares than could
    be covered by the over-allotment option, a naked short position, the
    position can only be closed out by buying shares in the open market. A
    naked short position is more likely to be created if the underwriters are
    concerned that there could be downward pressure on the price of the shares
    in the open market after pricing that could adversely affect investors who
    purchase in the offering.

  . 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 stabilizing or syndicate covering
    transaction to cover syndicate short positions.

These stabilizing transactions, syndicate covering transactions and penalty
bids may have the effect of raising or maintaining the market price of our
common stock or preventing or retarding a decline in the market price of the
common stock. As a result the price of the common stock may be higher than the
price that might otherwise exist in the open market. These transactions may be
effected on The Nasdaq National Market or otherwise and, if commenced, may be
discontinued at any time.

   A prospectus in electronic format may be made available on the Web sites
maintained by one or more of the underwriters participating in this offering.
The representatives may agree to allocate a number of shares to underwriters
for sale to their online brokerage account holders. Internet distributions will
be allocated by the underwriters that will make Internet distributions on the
same basis as other allocations.

                          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 made. Any resale of the common stock in Canada must
be made under applicable securities laws which will vary depending on the
relevant jurisdiction, and which may require resales to be made under 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

   By purchasing common stock in Canada and accepting a purchase confirmation a
purchaser is representing to us and the dealer from whom the purchase
confirmation is received that:

  . the purchaser is entitled under applicable provincial securities laws to
    purchase the common stock without the benefit of a prospectus qualified
    under those securities laws,

  . where required by law, that the purchaser is purchasing as principal and
    not as agent, and

  . 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 or such persons. All or a substantial portion of the assets of
the issuer and such persons may be located outside of Canada and, as a result,
it may not be possible to satisfy a judgment against the issuer or such persons
in Canada or to enforce a judgment obtained in Canadian courts against such
issuer or 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 such purchaser is required to file with the British
Columbia Securities Commission a report within ten days of such sale of any
common stock acquired by the purchaser pursuant to this offering. The 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 for 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 about the eligibility of the common
stock for investment by the purchaser under relevant Canadian legislation.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholders of
Plumtree Software, Inc.:

   We have audited the accompanying balance sheets of Plumtree Software, Inc.
(a California corporation) as of December 31, 1998 and 1999, and the related
statements of operations, stockholders' equity and cash flows for the three
years in the period ended December 31, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

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

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

            (Information as of June 30, 1999 and 2000 is unaudited)

1. Organization of the Company

   Plumtree Software, Inc. (the "Company") is a California company incorporated
on July 18, 1996 to develop and market infrastructure software and services
that enable a business to deploy a corporate portal to information applications
and Internet-based services.

   The Company is subject to a number of risks associated with companies at a
similar stage of development including competition from larger, more
established companies, dependence on new product introductions, volatility of
the industry, ability to obtain adequate funding to support growth, dependence
on key individuals and the ability to attract and retain additional qualified
personnel to manage the anticipated growth of the Company.

2. Significant Accounting Policies

 Unaudited Interim Financial Statements

   The accompanying financial statements as of June 30, 2000, and for the six
months ended June 30, 1999 and 2000, are unaudited, but in the opinion of
management include all adjustments consisting of normal recurring adjustments
necessary for a fair presentation of results for the interim periods. Certain
information and footnote disclosures normally included in financial statements
prepared in accordance with generally accepted accounting principles have been
omitted, although the Company believes that the disclosures included are
adequate to make the information presented not misleading. Results for the six
months ended June 30, 2000, are not necessarily indicative of the results that
may be expected for the year ending December 31, 2000.

 Unaudited Pro Forma Stockholders' Equity

   The Company's Board of Directors authorized the filing of a registration
statement with the Securities and Exchange Commission to register shares of its
common stock in connection with a proposed initial public offering (the "IPO").
If the IPO is consummated under the terms presently anticipated, all of the
currently outstanding shares of convertible preferred stock will be converted
into 16,580,830 shares of common stock upon the closing of the IPO. The effect
of the convertible preferred stock conversion has been reflected as unaudited
pro forma stockholders' equity in the accompanying balance sheet as of June 30,
2000.

 Cash and Cash Equivalents

   For purposes of the statement of cash flows, the Company considers
investments with an original maturity of three months or less from the date of
purchase to be cash and cash equivalents.

 Concentration of Credit Risk

   Two customers accounted for 17% and 12%, respectively, of accounts
receivable at December 31, 1999. Four customers accounted for 46%, 26%, 13% and
13%, respectively, of accounts receivable at December 31, 1998. Three customers
accounted for 25%, 17% and 12%, respectively, of net sales for fiscal year
1998.

 Property and Equipment

   Property and equipment are stated at cost. Depreciation is provided using
the straight-line method over the estimated useful lives of three to four
years.

            (Information as of June 30, 1999 and 2000 is unaudited)


 Stock-Based Compensation

   The Financial Accounting Standards Board issued 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, "Accounting for Stock Issued
to Employees" ("APB 25") 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. The Company has elected to continue to account
for its stock-based compensation arrangements under the provisions of APB 25,
and, accordingly, it has included in Note 9 the pro forma disclosures required
under SFAS No. 123.

 Software Development Costs

   The Company accounts for internally generated software development costs in
accordance with Statement of Financial Accounting Standards ("SFAS") No. 86,
"Accounting for the Costs of Computer Software to be Sold, Leased or Otherwise
Marketed." Capitalization of software development costs begins upon the
establishment of technological feasibility of the product, which the Company
defines as the development of a working model and further defines as the
completion of beta testing of the software. The establishment of technological
feasibility and the ongoing assessment of the recoverability of these costs
requires considerable judgment by management with respect to certain external
factors, including, but not limited to, anticipated future gross product
revenue, estimated economic life and changes in technology. Such costs are
reported at the lower of unamortized cost or net realizable value. To date,
internal software development costs that were eligible for capitalization have
been insignificant and the Company has charged all software development costs
to research and development expense as incurred.

 Use of Estimates

   The preparation of financial statements in conformity with accounting
principles generally accepted in the United States 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 revenues and expenses
during the reporting period. Actual results could differ from those estimates.

 Revenue Recognition

   License revenue consists principally of revenue from the licensing of the
Company's software and is generally recognized when a contract is executed, all
shipment obligations have been met, collection of the fee is fixed or
determinable, and collectibility is probable. When licenses are sold together
with services, in accordance with the provisions the American Institute of
Certified Public Accountants' Statement of Position 97-2, "Software Revenue
Recognition," 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 services, and (3) the services do not include
significant modifications to the features and functionality of the software.

   For arrangements which require delivery of unspecified future products over
a period, the Company uses the subscription method and recognizes revenue
ratably over the period.

   For arrangements in which payment of license fees are dependent upon the
performance of services, both the license revenue and service revenues are
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.

   Service revenue consists of consulting, training and installation services
that the Company provides to its customers. Revenue from such services, when
not sold in conjunction with product licenses, is generally recognized as the
service is performed. If services are bundled with a license agreement, amounts
related to services are unbundled from the license fee based on vendor specific
objective evidence as established by transactions where such services have been
sold separately.

   Maintenance revenue relates to the Company providing technical support and
software updates to customers. Revenue on maintenance contracts is recognized
ratably over the term of the contract. If maintenance is bundled with a license
agreement, amounts related to maintenance are unbundled from the license fee
based on vendor specific objective evidence as established by transactions
where such services have been sold separately.

 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. In accordance
with SFAS No. 128, basic net loss per share is calculated by dividing net loss
by the weighted average common shares outstanding during the period, less
shares subject to repurchase. Diluted income per share is calculated by
dividing the net income by the weighted average common shares outstanding
adjusted for all potential common shares, which includes shares issuable upon
the exercise of outstanding common stock options, convertible preferred stock,
warrants, and other contingent issuances of common stock.

   The Company has excluded all convertible preferred stock, warrants for
convertible preferred stock, outstanding stock options, and shares subject to

all such securities are antidilutive for all periods presented.

   Common stock subject to repurchase includes founder's stock and common stock
issued pursuant to unvested options exercises (see Notes 9 and 10).

   Pursuant to the Securities and Exchange Commission Staff Accounting Bulletin
No. 98, convertible preferred stock and common 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 they had been outstanding for all periods
presented. To date, the Company has not had any issuances or grants for nominal
consideration.

 Pro Forma Net Loss Per Share (unaudited)

   The calculation of pro forma net loss per share assumes that all series of
convertible shares have been converted into common stock as of the original
issuance date.

 Stock Split

   In July 1999, the Company amended and restated the Articles of Incorporation
which included a three for two stock split of the Company's common and
preferred shares which became effective immediately. All share and per share
information in these financial statements have been retroactively adjusted to
reflect this stock split.

 Segment Reporting

   As of June 30, 2000, management has concluded that the Company only operates
in one segment and almost exclusively in the United States.

 Comprehensive Income (Loss)

   In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
"Reporting Comprehensive Income," which the Company 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

                                      F-10

                   NOTES TO FINANCIAL STATEMENTS--(Continued)
            (Information as of June 30, 1999 and 2000 is unaudited)

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 (loss) and all other non-owner changes in shareholders' equity.
The Company's only component of comprehensive income is net loss.

 Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board 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 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 the Company). In June 2000, the FASB issued Statement No. 138, "Accounting
for Certain Derivative Instruments and Certain Hedging Activities--an Amendment
of FASB Statement No. 133." SFAS 138 amends SFAS 133 to (a) exclude from the
scope of SFAS No. 133 nonfinancial assets that will be delivered in quantities
expected to be used or sold by a company over a reasonable period in the normal
course of business and for which physical delivery is probable, (b) permit
hedging of a benchmark interest rate, (c) allow hedging of foreign-currency-
denominated assets and liabilities and (d) allow for limited hedging of net
foreign currency exposures. The Company has no derivative financial and
commodity instruments, forward contracts or hedging arrangements in cash and
cash equivalents. These statements should not have a material impact on the
current financial condition or results of the Company's operations.

   In December 1998, the AICPA issued 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. This statement did not have a material impact on the financial
condition or results of the Company's operations.

   In December 1999, the Securities and Exchange Commission issued Staff
Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial
Statements." SAB 101 provides guidance on applying generally accepted
accounting principles to revenue recognition issues in financial statements.
The Company has adopted SAB 101 as required for companies filing initial public
offerings.

   In March 2000, the Financial Accounting Standards Board issued FASB
Interpretation No. 44, "Accounting for Certain Transactions Involving Stock
Compensation (an Interpretation of APB Opinion No. 25)" ("FIN 44"). FIN 44
provides guidance on the application of APB 25, particularly as it relates to
options. The effective date of FIN 44 is July 1, 2000 and the Company has
adopted FIN 44 as of that date.

for a period of five years or (ii) upon the closing of an initial public
offering, whichever is earlier. The estimated fair value of the warrant at the
date of issuance was approximately $61,000. This amount was recognized as
additional interest expense over the term of the arrangement with the bank.

   In April 2000, in connection with the extension of the lease line discussed
in Note 6, a warrant was issued to the leasing company to purchase 11,250
shares of common stock at $2.00 per share. The right to purchase the common
stock was immediately effective upon signing and exercisable for a period of
seven years. The estimated fair value of the warrant at the date of issuance
was approximately $45,000. This amount will be recognized as additional
interest expense over the term of the lease line which expires in 2003.

   In May 2000, in connection with the extension of an operating lease, a
warrant was issued to the leasing company to purchase 32,391 shares of common
stock at $9.60 per share. The right to purchase the common stock was
immediately effective upon signing and exercisable for a period of six years.
The estimated fair value of the warrant at the date of issuance was
approximately $155,000. This amount will be recognized as additional rent
expense over the term of the operating lease which expires in 2006.

   In May 2000, the Company entered into a research and development agreement
with a customer and stockholder. A warrant was issued to this customer to
purchase 100,000 shares of common stock at $2.00 per share. The right to
purchase the common stock vests 20,000 shares per month for 5 consecutive
months and is exercisable for a period of four months. The estimated fair value
of the warrants which were vested as of June 30, 2000 was approximately
$115,000 and was recognized as research and development expense in the
accompanying statement of operations for the six months ended June 30, 2000.
The unvested warrants will be recognized as research and development expense as
vesting occurs.

   The fair market value of warrants on the date of grant was computed using
the Black-Scholes pricing model with the following assumptions: risk-free
interest rates ranging from 5.6 percent to 6.8 percent, expected dividend yield
of 0 percent, contractual lives of 0.4 to 7 years, and expected volatility of
70 percent.

9. 1997 EQUITY INCENTIVE PLAN

   In June 1997, the Company adopted the 1997 Equity Incentive Plan (the
"Plan") and reserved 4,200,000 shares of common stock for issuance thereunder.
Under the Plan, the board of directors may grant incentive and nonqualified
stock options to purchase shares of the Company's common stock to employees,
directors and consultants of the Company. The exercise price per share for an
incentive stock option cannot be less than 100% of the fair market value as
determined by the board of directors on the date of grant. The exercise price
per share for nonqualified stock options cannot be less than 85% of the fair
market value, as determined by the board of directors, on the date of grant.
Options generally expire ten years after the date of grant and generally vest
over a four year period. In addition, the option holder is entitled to exercise
prior to the option's vesting as long as he or she is still an employee. Should
the employee subsequently leave, the Company has the right to repurchase
unvested shares at the exercise price as of the departure date. Option activity
under the Plan through June 30, 2000 was as follows:

   At June 30, 2000, 1,544,280 shares of common stock were subject to
repurchase by the Company. As a result of the early exercise provision, all
options outstanding were exercisable at June 30, 2000.

   The Company accounts for its stock option plans pursuant to 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 amounts):

</TABLE>

   In connection with the grant of certain stock options to employees during
the year ended December 31, 1999, the Company recorded stock-based compensation
of approximately $1.4 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 on an
accelerated basis over the vesting period of the applicable options, generally
four years. Approximately $325,000 was expensed during the year ended December
31, 1999. In connection with the grant of certain stock options to employees
during the six months ended June 30, 2000, the Company recorded stock-based
compensation of approximately $9.4 million. Approximately $1.1 million was
expensed during the six months ended June 30, 2000. 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 year ended December 31, 1999, the Company issued options to
acquire approximately 14,000 shares of common stock to non-employees. The
options were immediately exercisable on the date of grant. The fair value of
the options on the date of grant was computed using the Black-Scholes pricing
model with the following assumptions: risk-free interest rates ranging from 6.0
percent to 6.2 percent, expected dividend yield of 0 percent, contractual lives
of 4 years and expected volatility of 70 percent. The estimated fair value of
the options was immaterial.

   In April 2000, the Company issued 19,618 shares of common stock in exchange
for services. The common stock was issued without restrictions. The estimated
fair value of the stock was approximately $100,000 and was recognized as
general and administrative expense in the accompanying statement of operations
for the six-month period ended June 30, 2000.

10. COMMON STOCK

   As of June 30, 2000, the Company has issued an aggregate of 4,890,470 shares
of common stock to founders of the Company, all of which were subject to
repurchase rights in the event of termination of employment, at the option of
the Company, at $0.01 per share. Such repurchase rights expire at 50% on the
date of issuance and the remaining 50% expire ratably over a three-year period
commencing on the date of issuance. These rights of repurchase terminated in
January 2000.

   In February 1998, the Company repurchased 833,040 shares of common stock
from a founder at $0.01 per share.

   In 1997, the Company charged compensation expense of approximately $63,000
related to common stock issued to the Company's founders.

11. INCOME TAXES

   The Company accounts for income taxes pursuant to the provisions of SFAS No.
109, "Accounting for Income Taxes." SFAS 109 requires recognition of deferred
tax liabilities and assets for the expected future tax consequences of events
that have been included in the financial statements or tax returns. Under this
method, deferred tax liabilities and assets are determined using the current
applicable enacted tax rate and provisions of the enacted tax law. The
components of the net deferred tax asset are as follows (in thousands):

</TABLE>

   The Company has net operating loss carryforwards as of June 30, 2000 of
approximately $11.9 million and $7.1 million, respectively, to offset future
federal and state taxable income. The net operating loss carryforwards expire
at various dates through the year 2020. The state loss carryforward will expire
commencing in 2005. A valuation allowance has been recorded for the entire net
deferred tax asset as a result of management's uncertainties regarding
realization of the asset including limited operating history of the Company,
the lack of profitability and uncertainty over future operating profitability
and taxable income.

   The Tax Reform Act of 1986 contains provisions which may limit the net
operating loss and credit carryforwards to be used in any given year upon the
occurrence of certain events, including a significant change in ownership
interest.

Item 14. Indemnification of Directors and Officers.

   Section 102 of the Delaware General Corporation Law, or the DGCL, as
amended, allows a corporation to eliminate the personal liability of directors
of a corporation to the corporation or its stockholders for monetary damages
for a breach of fiduciary duty as a director, except where the director
breached his duty of loyalty, failed to act in good faith, engaged in
intentional misconduct or knowingly violated a law, authorized the payment of a
dividend or approved a stock repurchase in violation of Delaware corporate law
or obtained an improper personal benefit.

   Section 145 of the DGCL provides, among other things, that we may indemnify
any person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding (other than an
action by or in the right of Plumtree) by reason of the fact that the person is
or was a director, officer, agent or employee of Plumtree or is or was serving
at our request as a director, officer, agent, or employee of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses, including attorneys' fees, judgment, fines and amounts paid in
settlement actually and reasonably incurred by the person in connection with
the action, suit or proceeding. The power to indemnify applies (a) if the
person is successful on the merits or otherwise in defense of any action, suit
or proceeding, or (b) if the person acted in good faith and in a manner he
reasonably believed to be in the best interest, or not opposed to the best
interest, of Plumtree, and with respect to any criminal action or proceeding,
had no reasonable cause to believe his conduct was unlawful. The power to
indemnify applies to actions brought by or in the right of Plumtree as well,
but only to the extent of defense expenses (including attorneys' fees but
excluding amounts paid in settlement) actually and reasonably incurred and not
to any satisfaction of judgment or settlement of the claim itself, and with the
further limitation that in these actions no indemnification shall be made in
the event of any adjudication of negligence or misconduct in the performance of
his duties to Plumtree, unless the court believes that in light of all the
circumstances indemnification should apply.

   Section 174 of the DGCL provides, among other things, that a director who
willfully or negligently approves of an unlawful payment of dividends or an
unlawful stock purchase or redemption may be held liable for these actions. A
director who was either absent when the unlawful actions were approved or
dissented at the

                                      II-1
<PAGE>

time, may avoid liability by causing his or her dissent to these actions to be
entered in the books containing the minutes of the meetings of the board of
directors at the time the action occurred or immediately after the absent
director receives notice of the unlawful acts.

   Our Amended and Restated Certificate of Incorporation includes a provision
that eliminates the personal liability of our directors for monetary damages
for breach of fiduciary duty as a director, except for liability:

  . for any breach of the director's duty of loyalty to Plumtree or its
    stockholders;

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

  . under section 174 of the Delaware General Corporation Law regarding
    unlawful dividends and stock purchases; or

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

   These provisions are permitted under Delaware law.

   Our Amended and Restated Bylaws provide that:

  . we must indemnify our directors and officers to the fullest extent
    permitted by Delaware law;

  . we may indemnify our other employees and agents to the same extent that
    we indemnified our officers and directors, unless otherwise determined by
    our board of directors; and

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

   The indemnification provisions contained in our Amended and Restated
Certificate of Incorporation and Amended and Restated Bylaws are not exclusive
of any other rights to which a person may be entitled by law, agreement, vote
of stockholders or disinterested directors or otherwise. In addition, we
maintain insurance on behalf of our directors and executive officers insuring
them against any liability asserted against them in their capacities as
directors or officers or arising out of this status.

   We intend to enter into agreements to indemnify our directors and executive
officers, in addition to indemnification provided for in our bylaws. These
agreements, among other things, will 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
the 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.

Item 17. Undertakings.

   The undersigned Registrant hereby undertakes to provide to the Underwriters
at the closing certificates in the denominations and registered in the names as
required by the Underwriters to permit prompt delivery to each purchaser.

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, and controlling persons of the
registrant pursuant to the provisions described in Item 14, or otherwise, the
registrant has been informed that in the opinion of the Securities and Exchange
Commission

                                      II-5
<PAGE>

such indemnification is against public policy as expressed in the Securities
Act and is therefore unenforceable. In the event that a claim for
indemnification by the registrant against such liabilities (other than the
payment by the registrant of expenses incurred or paid by a director, officer,
or controlling person of the registrant in the successful defense of any
action, suit, or proceeding) is asserted by such director, officer, or
controlling person in connection with the securities being registered, the
registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against pubic 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 of
      1933, 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 under 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
      of 1933, 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.

Registration Statement and (ii) Registration Statements, and any and all
amendments thereto (including post-effective amendments), relating to the
offering contemplated pursuant to Rule 462(b) under the Securities Act of 1933,
and to file the same, with all exhibits thereto, and other documents in
connection therewith, with the Securities and Exchange Commission, and hereby
grants to such attorneys-in-fact and agents full power and authority to do and
perform each and every act and thing requisite and necessary to be done, as

hereby ratifying and confirming all that said attorneys-in-fact and agents or

hereof.
