                               PROSPECTUS SUMMARY

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

                                  OUR BUSINESS

     Extensity provides Internet-based software applications designed to improve
the productivity of employees across an enterprise and to enhance enterprise
operating efficiency. We sell an integrated application suite that automates
expense reporting, travel management, procurement and billable time management.
These applications streamline traditionally inefficient and largely paper-based
processes, and capture cost savings by automatically enforcing spending policies
and tracking information valuable to management.

     In the intensely competitive global business environment, businesses have
increasingly adopted the Internet to streamline their business processes and
make their employees more productive. According to preliminary estimates by
International Data Corporation, the worldwide market for workforce management
applications will grow from $766 million in 1998 to $4.0 billion in 2003, and
the Internet commerce procurement applications market will grow from $147
million in 1998 to $5.3 billion in 2003.

     Our objective is to become the leading Internet-based point of
interactivity between a company's workforce and third-party content, commerce
and service providers. We have designed our applications to be readily
integrated with Internet-based third-party content, commerce and services. This
will enable us and our partners to deliver relevant and timely content and
business-to-business services targeted at the specific needs of employees. For
example, a consultant planning an engagement can obtain internal travel expense
approval, book airline tickets and hotel reservations through a travel service
partner, plan business entertainment through a content partner, track billable
time and record additional expenses for rapid approval and reimbursement - all
through our integrated application suite accessible at the office or on the
road. The growing network of organizations and employees using our applications
will constitute a valuable target market for our Internet-based content,
commerce and service partners.

     Our applications can be readily integrated with enterprise resource
planning and other information technology software applications commonly used in
organizations, including older, legacy systems. Our applications are universally
accessible through a variety of devices including networked and mobile PCs and
handheld computing devices, such as a PalmPilot or Visor. The architecture of
our products typically enables us to fully install our applications for use by
our customers in less than 90 days. Since the introduction of our first
application in 1998, we have licensed our products to 70 customers, the largest
of which, based on contract value, include AT Kearney, Cisco Systems, Gelco
Information Network, Sara Lee and TransCanada PipeLines.

                                  RISK FACTORS

     Any investment in our common stock involves a high degree of risk. You
should consider carefully the following information about these risks, together
with the other information contained in this prospectus, before you decide
whether to buy our common stock. If any of the following risks actually occur,
our business, results of operations and financial condition could suffer
significantly. In any such case, the market price of our common stock could
decline, and you may lose all or part of the money you paid to buy our common
stock.

                         RISKS RELATED TO OUR BUSINESS

OUR EXTREMELY LIMITED OPERATING HISTORY AND THE FACT THAT WE OPERATE IN A NEW
INDUSTRY MAKES OUR BUSINESS PROSPECTS DIFFICULT TO EVALUATE.

     We were incorporated in 1995 and commenced licensing of our software
applications in March 1998. Accordingly, we have an extremely limited operating
history. An investor in our common stock must consider the risks, uncertainties,
expenses and difficulties frequently encountered by companies in their early
stages of development, particularly companies in new and rapidly evolving
markets such as the market for Internet-based software applications. Risks and
difficulties include our ability to:

     - expand our base of customers with fully installed and deployed systems
       that can serve as reference accounts for our ongoing sales efforts;

     - expand our pipeline of sales prospects in order to promote greater
       predictability in our period-to-period sales levels;

     - continue to offer new products that complement our existing product line,
       in order to make our suite of applications more attractive to customers;

     - continue to develop and upgrade our technology to add additional features
       and functionality;

     - continue to attract and retain qualified personnel;

     - expand sales channels through geographic expansion and the development of
       indirect channels such as relationships with OEM customers and
       application service providers;

     - increase awareness of our brand; and

     - maintain our current, and develop new, third-party relationships.

     We cannot assure you that our business strategy will be successful or that
we will successfully address these risks or difficulties. If we fail to address
these risks or difficulties adequately, our business will likely suffer.

WE HAVE A HISTORY OF LOSSES AND NEGATIVE CASH FLOW AND EXPECT THIS TO CONTINUE
FOR THE FORESEEABLE FUTURE.

     Our business is new; we have offered products for a relatively short period
of time; and our base of customers and prospective customers is still relatively
small. We have spent significant funds to date to develop our current products
and to develop our sales and market resources. We have incurred significant
operating losses and have not achieved profitability. As of December 31, 1999,
we had an accumulated deficit of $40.0 million. We expect to continue to invest
in research and development to enhance current products and develop future
products.

                                        4
<PAGE>   12

We also plan to continue to grow our sales force and to spend significant funds
in marketing to promote our company and our products. We expect to continue to
hire additional people in all other areas of our company in order to support our
growing business. As a result, we will need to increase our revenues
significantly to achieve profitability. In addition, because we expect to
continue to invest in our business ahead of anticipated future revenues, we
expect that we will continue to incur operating losses for the foreseeable
future.

OUR BUSINESS IS CHANGING RAPIDLY, WHICH COULD CAUSE OUR QUARTERLY OPERATING
RESULTS TO VARY AND OUR STOCK PRICE TO FLUCTUATE.

     Our revenues and operating results may vary significantly from quarter to
quarter due to a number of factors, many of which are beyond our control. We
expect to continue to expend significant sums in all areas of our business,
particularly in our sales and marketing operations, in order to promote future
growth. Because the expenses associated with these activities are relatively
fixed in the short-term, we may be unable to adjust spending quickly enough to
offset any unexpected shortfall in revenue growth or any decrease in revenue
levels. As a result, we expect our quarterly operating results to fluctuate.
Moreover, because we use the percentage-of-completion method of contract
accounting with respect to recognition of license and implementation fees, if
our professional service organization is unable to implement our applications
for use by customers within our anticipated time frames, our recognition of
revenue for that customer could be deferred, which could cause our quarterly
revenue to fluctuate. Our financial results may as a consequence of quarterly
revenue fluctuations fall short of the expectations of public market analysts or
investors. If this occurs, the price of our common stock may drop.

     We also seek to develop and maintain a significant pipeline of potential
sales prospects, but it is difficult to predict when individual customer orders
will be closed. Our base of customers and the number of additional customer
licenses we enter into each quarter are still relatively small. Accordingly, the
loss or deferral of a small number of anticipated large customer orders in any
quarter could result in a significant shortfall in revenues for that quarter and
future quarters, which could result in a drop in the price of our stock.

     Other important factors which could cause our quarterly results and stock
price to fluctuate materially include:

     - our ability to grow our customer base and our base of referencing
       customers, in light of our relatively limited number of customers to
       date;

     - our ability to successfully develop alternative sales channels for our
       products (such as OEM sales through application service providers and
       application vendors) in light of our limited sales to date other than
       direct sales;

     - our ability to expand our implementation and consulting resources through
       third-party relationships, in light of the fact that we have no
       third-party implementation or consulting relationships currently in
       place; and

     - technical difficulties or "bugs" affecting the operation of our software.

     Due to our limited operating history, the early stage of our market and the
factors discussed above, you should not rely on quarter-to-quarter comparisons
of our results of operations as indicators of our future performance.

                                        5
<PAGE>   13

OUR BUSINESS WILL SUFFER IF WE DO NOT SIGNIFICANTLY EXPAND OUR SALES
CAPABILITIES.

     We sell our workforce optimization applications primarily through our
direct sales force. We must significantly expand our direct sales operations to
increase our revenues. We cannot be certain that we will be successful in these
efforts. Our products and services require sophisticated sales efforts and our
ability to increase our direct sales operation will depend on our ability to
recruit, train and retain top sales people with effective sales skills and
advanced technical knowledge. Competition for qualified personnel is intense in
our industry. Moreover, new sales personnel require training and take time to
achieve full productivity. If we are unable to hire or retain qualified sales
personnel, if newly hired personnel fail to develop the necessary skills, or if
they reach productivity more slowly than anticipated, we may be unable to grow
our revenues as rapidly as planned, if at all, and our business could be harmed.

WE FACE INTENSE COMPETITION, WHICH COULD AFFECT OUR ABILITY TO INCREASE REVENUE,
MAINTAIN OUR MARGINS AND INCREASE OUR MARKET SHARE.

     The market for our Internet-based workforce optimization applications is
intensely competitive and we expect competition to increase in the future.
Competitors vary in size and in the scope and breadth of the products and
services they offer. Companies offering one or more products directly
competitive with our products include Ariba, Captura Software, Concur
Technologies and IBM. We also expect to encounter competition in the near future
from major enterprise software vendors such as Oracle, PeopleSoft and SAP, to
the extent they enhance their existing product offerings with competitive
workforce optimization applications. As a result of the large market opportunity
for workforce optimization applications, we also expect competition from other
established and emerging companies. For example, as the emergence of the
application service provider (ASP) market enables hosted solutions from our
competitors to become broadly available, our future success may also depend upon
our ability to establish successful relationships with leading ASPs.

     Many of our current and potential competitors have longer operating
histories, significantly greater financial, technical, marketing and other
resources, significantly greater name recognition and a larger installed base of
customers than us. In addition, many of our competitors have well-established
relationships with our current and potential customers and have extensive
knowledge of our industry. Current and potential competitors have established or
may establish cooperative relationships among themselves or with third parties
to increase the ability of their products to address customer needs.
Accordingly, it is possible that new competitors or alliances among competitors
may emerge and rapidly acquire significant market share. We also expect that
competition will increase as a result of industry consolidation. Increased
competition may result in price reductions, reduced margins and loss of market
share, any one of which could seriously harm our business.

IF WE DO NOT PROVIDE SOFTWARE APPLICATIONS AND RELATED SERVICES THAT MEET THE
CHANGING DEMANDS OF OUR CUSTOMERS, THE MARKET FOR OUR PRODUCTS WILL NOT GROW OR
MAY DECLINE, AND OUR PRODUCT SALES WILL SUFFER.

     To successfully implement our business strategy, we have to provide
software applications and related services that meet the demands of our
customers and prospective customers as the market and customer requirements
evolve. We expect that competitive factors will create a continuing need for us
to improve and add to our suite of software applications. Not only will we have
to expend significant funds and other resources to continue to improve our
existing suite of applications, but we must also properly anticipate, address
and respond to consumer preferences and demands. As organizations' needs change
with respect to their enterprise applications, our existing suite of software
applications may become obsolete or inefficient relative to our

                                        6
<PAGE>   14

competitors' offerings and may require modifications or improvements. The
addition of new products and services will also require that we continue to
improve the technology underlying our applications. These requirements could be
significant, and we may fail to fulfill them quickly and efficiently. If we fail
to expand the breadth of our applications quickly in response to customer needs,
or if these offerings fail to achieve market acceptance, the market for our
products will not grow or may decline, and our business may suffer
significantly.

     Our workforce optimization software products and related services have
accounted for all of our revenues to date. We anticipate that revenues from
these products and related services will continue to constitute substantially
all of our revenues for the foreseeable future. Consequently, our future
financial performance will depend, in significant part, upon the successful
development, introduction and customer acceptance of enhanced versions of our
workforce optimization applications and any new products or services that we may
develop or acquire. We cannot assure you that we will be successful in
enhancing, upgrading or continuing to effectively market our workforce
optimization applications, or that any new products or services that we may
develop or acquire will achieve market acceptance.

OUR REVENUES HAVE BEEN DERIVED FROM A RELATIVELY SMALL NUMBER OF CUSTOMERS, AND
THE LOSS OF A SMALL NUMBER OF MAJOR CUSTOMERS OR POTENTIAL CUSTOMERS COULD
ADVERSELY IMPACT OUR REVENUES OR OPERATING RESULTS.

     We licensed our first workforce optimization application in March 1998 and
have fully implemented our applications for only a limited number of customers
to date. As of December 31, 1999 we had licensed our applications to a total of
70 customers and had implemented the solutions for a total of 30 of these
customers. Moreover, as of December 31, 1999, we had not completed an
implementation of our Extensity Purchase Reqs or Extensity Timesheets
applications for any customers. We expect that we will continue to derive a
significant portion of our revenues from a relatively small number of customers
in the future. Accordingly, the loss of a small number of major customers could
materially and adversely affect our business, and the deferral or loss of
anticipated orders from a small number of prospective customers could materially
and adversely impact our revenues and operating results in any period.

IF WE FAIL TO ACHIEVE POSITIVE MARGINS ON SERVICE REVENUES IN THE FORESEEABLE
FUTURE, OUR RESULTS OF OPERATIONS COULD SUFFER.

     Our margins on service revenues to date have been negative and are expected
to continue to be negative for the foreseeable future. We cannot assure you that
we will achieve positive margins on our service revenues. Failure to achieve
positive margins on service revenues could cause our business to suffer. For
more information related to our costs associated with our service revenues, see
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Results of Operations."

WE HAVE LIMITED EXPERIENCE WITH LARGE-SCALE IMPLEMENTATIONS, WHICH ARE IMPORTANT
TO OUR FUTURE SUCCESS.

     We have limited experience in implementing our applications on a large
scale. As of December 31, 1999, our largest implementation included
approximately 3,000 employee users. We believe that the ability of large
customers to roll-out our products across large numbers of users is critical to
our future success. If our customers cannot successfully deploy our applications
on a large scale, or if they determine for any reason that our products cannot
accommodate large-scale deployment, our business could be harmed.

                                        7
<PAGE>   15

WE HAVE ONLY RECENTLY UNDERTAKEN TO CREATE A CONTENT AND COMMERCE GATEWAY
BETWEEN OUR CUSTOMERS' EMPLOYEES AND THIRD-PARTY PROVIDERS, AND OUR FUTURE
OPERATING RESULTS WILL DEPEND ON OUR ABILITY TO SUCCEED IN THIS STRATEGY.

     A key component of our business strategy includes establishing an
integrated point of access, or gateway, between the network of customer
employees that utilize our workforce optimization solution and third-party
content, commerce and service providers who consider this employee base to be
potentially valuable business customers. We have only begun to establish this
gateway and, to date, we have only established relationships with two content
providers (from which we have not yet derived revenues). We cannot assure you
that we will be successful in developing this gateway. Moreover, we cannot
assure you that our customers will consider a content and commerce gateway to be
a valuable feature of our workforce optimization applications, or that
third-party providers will choose to access our network of customer employees to
generate e-commerce. If a market for such a gateway develops and we are unable
to establish a compelling product offering within this market, or if we build a
gateway and the market for such an offering fails to mature, our business could
be seriously harmed.

     We expect to depend increasingly on a number of third parties to expand our
content and commerce gateway and thereby generate revenues. We cannot assure you
that third parties will regard our relationship with them as important to their
own respective businesses and operations. They may choose not to partner with us
or, after having established a partnership with us, they may reassess their
commitment to us at any time in the future and may develop their own competitive
services or products. Also, we cannot assure you that the content, products or
services of those companies that provide access or links to our network will
achieve market acceptance or commercial success. Accordingly, we cannot assure
you that our existing or prospective relationships will result in sustained
business partnerships, successful product or service offerings or the generation
of significant revenues for us.

IF WE FAIL TO EXPAND OUR RELATIONSHIPS WITH THIRD PARTIES THAT CAN PROVIDE
IMPLEMENTATION AND CONSULTING SERVICES TO OUR CUSTOMERS, WE MAY BE UNABLE TO
GROW OUR REVENUES AND OUR BUSINESS COULD BE HARMED.

     In order for us to focus more effectively on our core business of
developing and licensing software solutions, we need to establish relationships
with third parties that can provide implementation and consulting services to
our customers. Third-party implementation and consulting firms can also be
influential in the choice of workforce optimization applications by new
customers. If we are unable to establish and maintain effective, long-term
relationships with implementation and consulting providers, or if these
providers do not meet the needs or expectations of our customers, we may be
unable to grow our revenues and our business could be seriously harmed. As a
result of the limited resources and capacities of many third-party
implementation providers, we may be unable to attain sufficient focus and
resources from the third-party providers to meet all of our customers' needs,
even if we establish relationships with these third parties. If sufficient
resources are unavailable, we will be required to provide these services
internally, which could limit our ability to expand our base of customers. A
number of our competitors have significantly more established relationships with
these third parties and, as a result, these third parties may be more likely to
recommend competitors' products and services rather than our own. Even if we are
successful in developing relationships with third-party implementation and
consulting providers, we will be subject to significant risk, as we cannot
control the level and quality of service provided by third-party implementation
and consulting partners.

                                        8
<PAGE>   16

CUSTOMER SATISFACTION AND DEMAND FOR OUR PRODUCTS WILL DEPEND ON OUR ABILITY TO
EXPAND OUR PROFESSIONAL SERVICES ORGANIZATION.

     We believe that growth in our product sales depends on our ability to
provide our customers with professional services to assist with support,
training, consulting and initial implementation and deployment of our products
and to educate third-party systems integrators in the use of our products. As a
result, we plan to increase the number of professional services personnel to
meet these needs. New professional services personnel will require training and
take time to reach full productivity. We may not be able to attract or retain a
sufficient number of highly qualified professional services personnel.
Competition for qualified professional services personnel is intense due to the
limited number of people who have the requisite knowledge and skills. To meet
our customers' needs for professional services, we may also need to use more
costly third-party consultants to supplement our own professional services
group. In addition, we could experience delays in recognizing revenue if our
professional services group fails to complete implementations in a timely
manner.

OUR EXPECTATIONS OF FUTURE GROWTH DEPEND ON OUR ABILITY TO EXPAND
INTERNATIONALLY, AND FACTORS SPECIFIC TO OUR INTERNATIONAL EXPANSION MAY PREVENT
US FROM ACHIEVING OUR ANTICIPATED GROWTH.

     We intend to expand our international operations to achieve our anticipated
growth, but we may face significant challenges to our international expansion.
The expansion of our existing international operations and entry into additional
international markets will require significant management attention and
financial resources. To achieve broad acceptance in international markets, our
products must be internationalized to handle a variety of factors specific to
each international market, such as tax laws and local regulations. The
incorporation of these factors into our products is a complex process and often
requires assistance from third parties. We have limited experience in
internationalizing our products and we may not adequately address all of the
factors necessary to achieve broad acceptance in our target international
markets. Further, to achieve broad usage by employees across international
organizations, our products must be localized to handle native languages and
cultures in each international market. Localizing our products is also a complex
process and we intend to work with third parties to develop localized products.
To date, we have not localized our products for any international market and we
cannot assure you that our localization efforts will be successful.

     We have only a limited history of marketing, selling and supporting our
products and services internationally. In the second quarter of 1999, we opened
a sales office in the United Kingdom and established a relationship with an
international reseller. As of December 31, 1999, we had eight employees in the
United Kingdom office. To date, we have not derived any revenues from our
international operations. To expand internationally we must hire and train
experienced international personnel as well as export qualified domestic
personnel to staff and manage our international operations. However, we may
experience difficulties in recruiting and training an international staff. We
must also be able to enter into strategic relationships with companies in
international markets. If we are not able to maintain successful strategic
relationships internationally or recruit additional companies to enter into
strategic relationships, our future growth could be limited.

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

     - difficulties in collecting accounts receivable and longer collection
       periods;

     - seasonal business activity in certain parts of the world;

     - fluctuations in currency exchange rates; and

     - trade barriers.

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

WE ARE GROWING RAPIDLY, AND OUR FAILURE TO MANAGE THIS GROWTH COULD HARM OUR
BUSINESS.

     We have experienced and are currently experiencing a period of significant
growth. Our full-time employees increased from 35 at December 31, 1997 to 83 at
December 31, 1998 to 175 at December 31, 1999. This growth has placed a
significant strain on our resources. We expect that any future growth would
cause similar or increased strains on our resources. As part of this growth, we
will have to implement new operational and financial systems and procedures and
controls; expand, train and manage our employee base; and maintain close
coordination among our technical, accounting, finance, marketing and sales
staffs. If we are unable to manage our growth effectively, our business, results
of operations and financial condition could be adversely affected.

     Several members of our senior management joined us in 1999, including David
Yarnold, our Vice President of Business Development and Mark Oney, our Vice
President of Engineering. Although we believe that these individuals are
currently integrated with the other members of our management team, we cannot
assure you that our management team will be able to continue to work together
effectively or to manage our growth successfully. We believe that the successful
integration of our management team is critical to our ability to manage our
operations effectively and support our anticipated future growth.

WE MAY BE UNABLE TO ATTRACT OR RETAIN HIGHLY SKILLED EMPLOYEES THAT ARE
NECESSARY FOR THE SUCCESS OF OUR GROWTH PLAN.

     In addition to our dependence on our sales and professional services
personnel as previously discussed, our ability to execute our growth plan and be
successful also depends on our continuing ability to attract and retain highly
skilled employees. We depend on the continued services of senior management and
other personnel, particularly Robert A. Spinner, our Chief Executive Officer. As
we continue to grow, we will need to hire additional personnel in all
operational areas. Competition for personnel in our industry is intense. We have
in the past experienced, and we expect to continue to experience in the future,
difficulty in hiring and retaining highly skilled employees with appropriate
qualifications. If we do not succeed in attracting or retaining personnel, our
business could be adversely affected.

OUR SALES CYCLES ARE LONG AND UNPREDICTABLE, WHICH MAKES PERIOD-TO-PERIOD
REVENUES DIFFICULT TO PREDICT.

     Because the market for our workforce optimization software products and
related services is new, we experience long and unpredictable sales cycles. The
sales cycle for our workforce optimization applications typically ranges from
two to six months. In the early stages of this market, our customers have
frequently viewed the purchase of our products as part of a long-term strategic
decision regarding the management of their workforce-related operations and
expenditures. This decision process has sometimes resulted in customers taking a
long period of time to assess alternative solutions by our competitors or
deferring a purchase decision until the market evolves. Sales cycles continue to
be long and the timing of purchase decisions by individual customers remains at
times uncertain. We must continue to educate potential customers on the use and
benefits of our products and services, as well as the integration of our
products and services with additional software applications utilized by the
individual customers. Because the sales cycle is long and the time of individual
orders is uncertain, our period-to-period revenues are difficult to predict.

                                       10

EVOLVING TECHNOLOGICAL DEVELOPMENTS AND EMERGING INDUSTRY STANDARDS WILL REQUIRE
US TO ENHANCE THE FUNCTIONALITY OF OUR WORKFORCE OPTIMIZATION APPLICATIONS, AND
ANY INABILITY TO ENHANCE FUNCTIONALITY COULD CAUSE OUR SALES TO DECLINE.

     Because the market for our products is emerging and subject to rapid
technological change and evolving industry standards, the life cycles of our
products are difficult to predict. Competitors may introduce new products or
enhancements to existing products employing new technologies, which could render
our existing products and services obsolete and unmarketable. For example, our
currently available software applications are written entirely in the Java
computer language. While we believe that this provides our solution with
significant advantages in terms of functionality and flexibility, the market for
Java-based software is still relatively new and it is not clear whether
Java-based systems will continue to maintain commercial acceptance.

     To be successful, our products and services must keep pace with
technological developments and emerging industry standards, address the
ever-changing and increasingly sophisticated needs of our customers and achieve
market acceptance. Our results of operations would be seriously harmed if we are
unable to develop, release and market new software product enhancements on a
timely and cost-effective basis, or if new products or enhancements do not
achieve market acceptance or fail to respond to evolving industry or technology
standards.

     In developing new products and services, we may also fail to develop and
market products that respond to technological changes or evolving industry
standards in a timely or cost-effective manner, or experience difficulties that
could delay or prevent the successful development, introduction and marketing of
these new products and services.

SOFTWARE DEFECTS COULD LEAD TO LOSS OF REVENUE OR DELAY THE MARKET ACCEPTANCE OF
OUR APPLICATIONS.

     Our enterprise applications software is complex and, accordingly, may
contain undetected errors or failures when first introduced or as new versions
are released. This may result in loss of, or delay in, market acceptance of our
products. We have in the past discovered software errors in our new releases and
new products after their introduction. In the event that we experience
significant software errors in future releases, we could experience delays in
release, customer dissatisfaction and potentially lost revenues during the
period required to correct these errors. We may in the future discover errors,
including Year 2000 errors and additional scalability limitations, in new
releases or new products after the commencement of commercial shipments. Any of
these errors or defects could cause our business to be materially harmed.

WE MAY BECOME INCREASINGLY DEPENDENT ON THIRD-PARTY SOFTWARE INCORPORATED IN OUR
PRODUCTS AND, IF SO, IMPAIRED RELATIONS WITH THESE THIRD PARTIES, ERRORS IN
THIRD PARTY SOFTWARE OR INABILITY TO ENHANCE THE SOFTWARE OVER TIME COULD HARM
OUR BUSINESS.

     We incorporate third-party software into our products. Currently, the
third-party software we use includes application server software that we license
from BEA Systems. We expect to incorporate additional third-party software into
our products as we expand our product line and broaden the content and services
accessible through our gateway. The operation of our products would be impaired
if errors occur in the third-party software that we license. It may be more
difficult for us to correct any errors in third-party software because the
software is not within our control. Accordingly, our business would be adversely
affected in the event of any errors in this software. Furthermore, it may be
difficult for us to replace any third-party software if a vendor seeks to
terminate our license to the software.

                                       11
<PAGE>   19

OUR SUCCESS DEPENDS IN PART UPON OUR ABILITY TO PROTECT OUR INTELLECTUAL
PROPERTY, BUT WE MAY NOT BE ABLE TO DO SO ADEQUATELY.

     Our success depends in large part upon our proprietary technology. We rely
on a combination of copyright, trademark and trade secret protection,
confidentiality and nondisclosure agreements and licensing arrangements to
establish and protect our intellectual property rights. We license rather than
sell our solutions and require our customers to enter into license agreements,
which impose restrictions on their ability to utilize the software. In addition,
we seek to avoid disclosure of our trade secrets through a number of means,
including requiring those persons with access to our proprietary information to
execute nondisclosure agreements with us and restricting access to our source
code. We seek to protect our software, documentation and other written materials
under trade secret and copyright laws, which afford only limited protection.

     We currently have no patents, although we have filed eight provisional
patent applications with the U.S. Patent and Trademark Office relating to
various features and processes embodied in our applications. A provisional
patent application is a type of application under which a patent will not issue,
but which provides a priority date for a regular patent application that is
filed within a one year period following the filing of the provisional patent
application. We cannot assure you that any regular patents will be filed based
on our provisional applications, or that any patents will issue on our pending
provisional applications from any such regular patent applications. Further, we
cannot provide any assurance that any patents, if issued, will prevent the
development of competitive products or that our patents will not be successfully
challenged by others or invalidated through administrative process or
litigation.

     Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy aspects of our products or to obtain and use information
that we regard as proprietary. Policing unauthorized use of our products is
difficult, and while we are unable to determine the extent to which piracy of
our software products exists, software piracy can be expected to be a persistent
problem. In addition, the laws of some foreign countries do not protect our
proprietary rights to as great an extent as do the laws of the United States.
Our means of protecting our proprietary rights may not be adequate and our
competitors may independently develop similar technology, duplicate our
products, or design around our proprietary intellectual property.

WE MAY FACE COSTLY DAMAGES OR LITIGATION COSTS IF A THIRD PARTY CLAIMS THAT WE
INFRINGE ITS INTELLECTUAL PROPERTY.

     There has been a substantial amount of litigation in the software industry
and the Internet industry regarding intellectual property rights. It is possible
that in the future, third parties may claim that we or our current or potential
future products infringe upon their intellectual property. We expect that
software product developers and providers of Internet-based software
applications 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, with or without
merit, could be time consuming, result in costly litigation, cause product
shipment delays or require us to enter into royalty or licensing agreements.
Royalty or licensing agreements, if required, may not be available on terms
acceptable to us or at all, which could seriously harm our business.

UNDETECTED YEAR 2000 ISSUES COULD INVOLVE SIGNIFICANT TIME AND EXPENSE AND MAY
AFFECT OUR OPERATIONS.

     The risks posed by Year 2000 issues could adversely affect our business in
a number of significant ways. We believe after examining and testing our
products that our internally
                                       12
<PAGE>   20

developed technology, as well as the third-party technology incorporated into
our products, is Year 2000 compliant. Moreover, to date we have not detected any
disruptions in our software applications or in the applications of our vendors
arising from the roll-over to the Year 2000. Nonetheless, our products could
experience unexpected Year 2000 issues that we have failed to uncover to date
which could cause our products to be impaired. We also use third-party financial
and other systems in our internal business operations. Although we have received
assurances from most of our vendors that these systems are Year 2000 compliant,
and to our knowledge these products have not experienced Year 2000 disruptions
following the roll-over to the Year 2000, these systems could in the coming
weeks or months suffer from unexpected Year 2000 issues. Any such Year 2000
issues could materially adversely affect our business. Moreover, we may in the
future be required to defend our products or services in litigation or
arbitration proceedings involving our products or services related to Year 2000
compliance issues, or to negotiate resolutions of claims based on Year 2000
issues. Defending or resolving Year 2000-related disputes, regardless of the
merits of such disputes, and any liability we have for Year 2000-related
damages, including consequential damages, could be expensive.

     Moreover, we will experience fewer sales if potential customers, who might
otherwise purchase our software solutions, delay the purchase and implementation
of our solutions in the event their information technology budgets have been
diverted to address Year 2000 issues. If our potential customers delay
purchasing or implementing solutions as a result of the Year 2000 issue, our
business would be seriously harmed.

     We cannot guarantee that any of our participating partners or other
Internet vendors are Year 2000 compliant. We also cannot guarantee that our
customers will be able to utilize our software solutions without disruptions
arising from the Year 2000 issue. Moreover, the costs related to Year 2000
compliance, which thus far have not been material, could ultimately be
significant. In the event that we experience disruptions as a result of the Year
2000 issue, our business could be harmed. For more information regarding the
state of our Year 2000 readiness, see "Management's Discussion and Analysis of
Financial Condition and Results of Operations."

ANY FUTURE ACQUISITIONS OF COMPANIES OR TECHNOLOGIES MAY RESULT IN DISTRACTION
OF OUR MANAGEMENT AND DISRUPTIONS TO OUR BUSINESS.

     We may acquire or make investments in complementary businesses,
technologies, services or products if appropriate opportunities arise. From time
to time we may engage in discussions and negotiations with companies regarding
our acquiring or investing in such companies' businesses, products, services or
technologies. We cannot make assurances that we will be able to identify future
suitable acquisition or investment candidates, or if we do identify suitable
candidates, that we will be able to make such acquisitions or investments on
commercially acceptable terms or at all. If we acquire or invest in another
company, we could have difficulty assimilating that company's personnel,
operations, technology or products and service offerings. In addition, the key
personnel of the acquired company may decide not to work for us. These
difficulties could disrupt our ongoing business, distract our management and
employees, increase our expenses and adversely affect our results of operations.
Furthermore, we may incur indebtedness or issue equity securities to pay for any
future acquisitions. The issuance of equity securities could be dilutive to our
existing stockholders. As of the date of this prospectus, we have no agreement
to enter into any material investment or acquisition transaction.

                                       13
<PAGE>   21

WE HAVE ANTI-TAKEOVER PROVISIONS IN OUR CHARTER AND IN OUR CONTRACTS THAT COULD
DELAY OR PREVENT AN ACQUISITION OF OUR COMPANY, EVEN IF SUCH AN ACQUISITION
WOULD BE BENEFICIAL TO OUR STOCKHOLDERS.

     Provisions of our certificate of incorporation, our bylaws, Delaware law
and the employment agreements of some of our key officers could make it more
difficult for a third party to acquire us, even if doing so might be beneficial
to our stockholders. Please see "Description of Capital Stock" and "Compensation
Committee Interlocks and Insider Participation."

OUR BUSINESS MAY FACE ADDITIONAL RISKS AND UNCERTAINTIES NOT PRESENTLY KNOWN TO
US WHICH COULD CAUSE OUR BUSINESS TO SUFFER.

     In addition to the risks specifically identified in this Risk Factors
section or elsewhere in this prospectus, we may face additional risks and
uncertainties not presently known to us or that we currently deem immaterial
which ultimately may impair our business, results of operations and financial
condition.

                         RISKS RELATED TO OUR INDUSTRY

OUR SUCCESS WILL DEPEND UPON THE GROWTH AND ACCEPTANCE OF THE MARKET WE ADDRESS
AND OUR ABILITY TO MEET THE NEEDS OF THE EMERGING MARKET FOR OUR SOLUTIONS.

     The market for our workforce optimization applications and services is at
an early stage of development. Our success will depend upon the continued
development of this market and the increasing acceptance by customers of the
benefits to be provided by workforce optimization applications and services. In
addition, as the market evolves, it is unclear whether the market will accept
our suite of applications as a preferred solution for workforce optimization
needs. Accordingly, our products and services may not achieve significant market
acceptance or realize significant revenue growth. Unless a critical mass of
organizations and their suppliers use our solutions and recommend them to new
customers, our solutions may not achieve widespread market acceptance, which may
cause our business to suffer.

CUSTOMERS MAY NOT ACCEPT THE INTERNET AS A MEANS TO ACCESS ENTERPRISE
APPLICATIONS, AND THIS WOULD LIKELY CAUSE OUR BUSINESS MODEL TO BE UNSUCCESSFUL.

     To date, enterprises have generally managed operational functions through
internal computer systems rather than over the Internet. Our business model
assumes that enterprises and their employees will increasingly adopt the
Internet or corporate intranets as a means of managing important business
functions. This business model is not yet proven, and if we are unable to
successfully implement our business model, our business will be materially
adversely affected.

SECURITY RISKS AND CONCERNS MAY DETER THE USE OF THE INTERNET FOR CONDUCTING
ELECTRONIC COMMERCE.

     A significant barrier to electronic commerce and communications is the
secure transmission of confidential information over public networks. Advances
in computer capabilities, new discoveries in the field of cryptography or other
events or developments could result in compromises or breaches of our security
systems or those of other websites to protect proprietary information. If any
well-publicized compromises of security were to occur, it could have the effect
of substantially reducing the use of the Internet for commerce and
communications. Anyone who circumvents our security measures could
misappropriate

                                       14
<PAGE>   22

proprietary information or cause interruptions in our services or operations.
The Internet is a public network, and data is sent over this network from many
sources. In the past, computer viruses and software programs that disable or
impair computers have been distributed and have rapidly spread over the
Internet. Computer viruses could be introduced into our systems or those of our
customers or suppliers, which could disrupt our software solutions or make them
inaccessible to customers or suppliers. We may be required to expend significant
capital and other resources to protect against the threat of security breaches
or to alleviate problems caused by breaches. To the extent that our activities
may involve the storage and transmission of proprietary information, such as
credit card numbers, security breaches could expose us to a risk of loss or
litigation and possible liability. Our security measures may be inadequate to
prevent security breaches, and our business would be harmed if we do not prevent
them.

INCREASING GOVERNMENT REGULATION COULD LIMIT THE MARKET FOR, OR IMPOSE SALES AND
OTHER TAXES ON THE SALE OF, OUR PRODUCTS AND SERVICES.

     As Internet commerce evolves, we expect that federal, state or foreign
agencies will adopt regulations covering issues such as user privacy, pricing,
taxation of goods and services provided over the Internet, and content and
quality of products and services. It is possible that legislation could expose
companies involved in electronic commerce to liability, which could limit the
growth of electronic commerce generally. Legislation could dampen the growth in
Internet usage and decrease its acceptance as a communications and commercial
medium. If enacted, these laws, rules or regulations could limit the market for
our products and services.

                         RISKS RELATED TO THIS OFFERING

INVESTORS WILL BE RELYING ON OUR MANAGEMENT'S JUDGMENT REGARDING THE USE OF
PROCEEDS FROM THIS OFFERING.


     We do not have a definitive quantified plan with respect to the use of the
net proceeds of this offering and have not committed the substantial majority of
these proceeds to any particular purpose apart from the repayment of
approximately $3.1 million of outstanding debt and the allocation of up to
approximately $58.4 million for general working capital and business expenses,
as more fully described in "Use of Proceeds." Accordingly, our management will
have broad discretion with respect to the use of the net proceeds from this
offering, and investors will be relying on the judgment of our management
regarding the application of these proceeds. Some of the uses we currently
anticipate include expansion of our sales and marketing operations, increased
spending in the areas of research and development and customer support,
broadening our operational and administrative infrastructure, the leasing of
additional facilities and for working capital and other general corporate
purposes. We may also use a portion of the proceeds for strategic alliances and
acquisitions. These investments may not yield a favorable return. We have only
made preliminary determinations of the amount of net proceeds to be used
specifically for each of the foregoing purposes based upon our current
expectations regarding our financial performance and business needs over the
foreseeable future. These expectations may prove to be inaccurate, as our
financial performance may differ from our current expectations or our business
needs may change as our business and the industry we address evolve. As a
result, the proceeds we receive in this offering may be used in a manner
significantly different from our current allocation plans.


THE LIQUIDITY OF OUR COMMON STOCK IS UNCERTAIN SINCE IT HAS NOT BEEN PUBLICLY
TRADED.

     There has not been a public market for our common stock. We cannot predict
the extent to which investor interest in our company will lead to the
development of an active, liquid trading
                                       15
<PAGE>   23

market. Active trading markets generally result in lower price volatility and
more efficient execution of buy and sell orders for investors. The initial
public offering price for the shares 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.

OUR NEED FOR ADDITIONAL FINANCING IS UNCERTAIN AS IS OUR ABILITY TO RAISE
FURTHER FINANCING IF REQUIRED.

     We currently anticipate that our available cash resources, combined with
the net proceeds from this offering, will be sufficient to meet our anticipated
working capital and capital expenditure requirements for at least 12 months
after the date of this prospectus. We may need to raise additional funds,
however, to respond to business contingencies which may include the need to:

     - fund more rapid expansion;

     - fund additional marketing expenditures;

     - develop new or enhance existing products and services;

     - enhance our operating infrastructure;

     - hire additional personnel;

     - respond to competitive pressures; or

     - acquire complementary businesses or necessary technologies.

     If additional funds are raised through the issuance of equity or
convertible debt securities, the percentage ownership of our stockholders will
be reduced, and these newly-issued securities may have rights, preferences or
privileges senior to those of existing stockholders, including those acquiring
shares in this offering. We cannot assure you that additional financing will be
available on terms favorable to us, or at all. If adequate funds are not
available or are not available on acceptable terms, our ability to fund our
operations, take advantage of unanticipated opportunities, develop or enhance
our products and services or otherwise respond to competitive pressures would be
significantly limited.

MARKET PRICES OF INTERNET AND TECHNOLOGY COMPANIES HAVE BEEN HIGHLY VOLATILE,
AND THE MARKET FOR OUR STOCK MAY EXHIBIT VOLATILITY AS WELL.

     The stock market has experienced significant price and trading volume
fluctuations, and the market prices of technology companies generally, and
Internet-related companies particularly, have been extremely volatile. Recent
initial public offerings by technology companies have been accompanied by
exceptional share price and trading volume changes in the first days and weeks
after the securities were released for public trading. Investors may not be able
to resell their shares at or above the initial public offering price. In the
past, following periods of volatility in the market price of a public company's
securities, securities class action litigation has often been instituted against
that company. Such litigation could result in substantial costs and a diversion
of management's attention and resources.

NEW INVESTORS WILL SUFFER IMMEDIATE AND SUBSTANTIAL DILUTION IN THE TANGIBLE NET
BOOK VALUE OF THEIR SHARES.

     We expect the initial public offering price to be substantially higher than
the net tangible book value per share of the common stock. The net tangible book
value of a share of common

                                       16
<PAGE>   24


stock purchased at an assumed initial public offering price of $17.00 per share
will be only $3.34. Additional dilution may be incurred if holders of stock
options, whether currently outstanding or subsequently granted, exercise their
options or if warrantholders exercise their warrants to purchase common stock.


THE LARGE NUMBER OF SHARES ELIGIBLE FOR PUBLIC SALE AFTER THIS OFFERING COULD
CAUSE OUR STOCK PRICE TO DECLINE.

     The market price of our common stock could decline as a result of sales by
our existing stockholders of a large number of shares of our common stock in the
market after this offering or the perception that such sales could occur. These
sales also might make it more difficult for us to sell equity securities in the
future at a time and at a price that we deem appropriate. Please see "Shares
Eligible for Future Sale" for a description of sales that may occur in the
future.

MANY CORPORATE ACTIONS WILL BE CONTROLLED BY OFFICERS, DIRECTORS AND AFFILIATED
ENTITIES REGARDLESS OF THE OPPOSITION OF OTHER INVESTORS OR THE DESIRE OF OTHER
INVESTORS TO PURSUE AN ALTERNATIVE CAUSE OF ACTION.

     Our executive officers, directors and entities affiliated with them will,
in the aggregate, beneficially own approximately 43.8% of our common stock
following this offering. If they were to act together, these stockholders would
be able to exercise control over most matters requiring approval by our
stockholders, including the election of directors and approval of significant
corporate transactions. This concentration of ownership may also have the effect
of delaying or preventing a change in control of our company, which could have a
material adverse effect on our stock price. These actions may be taken even if
they are opposed by the other investors, including those who purchase shares in
this offering.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
                               AND INDUSTRY DATA

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

     This prospectus contains estimates of market growth related to the Internet
and e-commerce, as well as cost savings expected to be realized through
e-commerce. These estimates have been included in studies published by the
market research and other firms including American Express, Forrester Research,
International Data Corporation and Killen & Associates. These estimates have
been produced by industry analysts based on trends to date, their knowledge of
technologies and markets, and customer research, but these are forecasts only
and are subject to inherent uncertainty.

<PAGE>   25

                                USE OF PROCEEDS


     The net proceeds to us from the sale of the 4,000,000 shares being offered
by us at an assumed initial public offering price of $17.00 per share, after
deducting estimated underwriting discounts and commissions and estimated
offering expenses, are estimated to be approximately $61.5 million, or
approximately $71.0 million if the underwriters' over-allotment option is
exercised in full.


     We do not have specific uses committed for the preponderance of the net
proceeds of this offering. The size of the offering has been determined
primarily based upon our desire to raise a sufficient amount of capital to
afford to us significant business flexibility in the future.

     The principal purposes of this offering are:

     - to obtain additional working capital;

     - to create a public market for our common stock;

     - to facilitate future access by Extensity to public equity markets; and

     - to enhance our ability to use our stock to make future acquisitions due
       to the fact that our shares will be publicly traded.

     We intend to use a portion of the net proceeds of this offering to repay in
full outstanding indebtedness to Comdisco Ventures of approximately $1.8 million
under a loan and security agreement and approximately $1.3 million under various
capital leases. Indebtedness under the loan and security agreement has been
accruing interest at fixed rates ranging from 11.32% to 11.5% and matures
through March 25, 2001, and indebtedness under the capital leases accrue
interest at fixed rates ranging from 7.03% to 7.42% and mature at various dates
from March 2002 to July 2003.

     We expect to use the remainder of the net proceeds for working capital and
general corporate purposes, including increased spending on sales and marketing,
customer support, research and development, expansion of our operational and
administrative infrastructure, and the leasing of additional facilities. In
addition, we may use a portion of the net proceeds to acquire or invest in
complementary businesses, technologies, product lines or products. However, we
have no current plans, agreements or commitments with respect to any such
acquisition, and we are not currently engaged in any negotiations with respect
to any such transaction.


     Based on our current business model, we expect that we will spend
approximately $27.4 million of the net proceeds of this offering on sales and
marketing, $12.9 million on research and development, $12.9 million on service
and maintenance, and $5.2 million on general and administrative costs. These
figures are subject to change, however, depending upon our rate of revenue
growth, overall financial performance and evolving business needs. These
expectations may prove to be inaccurate, as our financial performance may differ
from our current expectations or our business needs may change as our business
model and the industry we address evolve. As a result, the proceeds we receive
from this offering may be used in a manner significantly different from our
current allocation plans. Pending use, we intend to invest the net proceeds in
short-term, interest-bearing, investment grade securities, certificates of
deposit or direct or guaranteed obligations of the U.S. government.


     The amounts we actually spend for these purposes may vary significantly and
will depend on a number of factors, including our future revenue and cash
generated by operations and the other factors described in "Risk Factors."
Therefore, we will have broad discretion in the way we use the net proceeds.

                                       18
<PAGE>   26

                                DIVIDEND POLICY

     The payment of dividends is within the discretion of our board of
directors. Our ability to pay any future dividends will depend on our earnings,
operating and financial condition, projected capital requirements, and
restrictions under our credit facilities. In this regard, our credit facility
with Comdisco Ventures restricts our ability to declare cash dividends without
the consent of Comdisco Ventures. Notwithstanding the foregoing, we have never
declared or paid any cash dividends on shares of our capital stock and do not
intend to do so at any time in the foreseeable future.

                                 CAPITALIZATION

     The following table sets forth the following information:

                                    DILUTION


     Our pro forma net tangible book value as of December 31, 1999, after giving
effect to the automatic conversion of our preferred stock upon the closing of
this offering, was $14.6 million, or $0.78 per share of common stock. Net
tangible book value per share is determined by dividing our tangible book value
(total tangible assets less total liabilities) by the number of outstanding
shares of common stock at that date. After giving effect to the sale of the
4,000,000 shares of our common stock offered hereby at an assumed initial public
offering price of $17.00 per share and after deducting estimated underwriting
discounts and commissions and estimated offering expenses, our net tangible book
value at December 31, 1999 would have been $76.1 million, or $3.34 per share.
This represents an immediate increase in net tangible book value to existing
stockholders of $2.56 per share and an immediate dilution to new investors of
$13.66 per share. The following table illustrates the per share dilution:

     The above discussion and tables assume no exercise of stock options or
warrants outstanding as of December 31, 1999 and gives effect to the conversion
of all shares of our preferred stock outstanding as of that date into common
stock upon completion of this offering. As of December 31, 1999, there were
options outstanding to purchase a total of 2,942,582 shares of common stock at a
weighted average exercise price of $2.02 per share under our 1996 Stock Plan,
1,649,215 additional shares were reserved for grant of future options under such
plan, and an aggregate of 500,000 shares of our common stock will be reserved
for issuance under our Employee Stock Purchase Plan 2000 upon completion of the
offering. To the extent that any of these options or warrants are exercised,
there will be further dilution to the new public investors. See
"Capitalization," "Management -- Compensation Plans" and Note 9 of Notes to
Consolidated Financial Statements.

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

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

OVERVIEW

     Extensity was formed in November 1995 and introduced its first commercial
product for general availability in March 1998. During this period, our
operating activities consisted of the design and development of our product
architecture and our first application, the building of our corporate
infrastructure, and the development of our professional services and customer
support organizations. Our first application, Extensity Expense Reports, was
released for general availability in March 1998. We released Extensity Travel
Plans in December 1998, and Extensity Timesheets and Extensity Purchase Reqs in
July 1999.

     We generate revenue principally from licensing our applications and
providing related services, including product installation, maintenance and
support, consulting and training. We license our applications individually or as
an integrated suite of products. The pricing of our software and services
fluctuates on a per transaction basis depending on various factors, such as the
number of seats covered by a contract and the frequency of users (i.e., the
number of times a customer's employees are likely to access our applications).
The dollar amounts of our contracts depends on number of users and applications
being used. License revenues comprised 64% and 55% of our total revenues in the
years ended December 31, 1998 and 1999, respectively, while services and other
revenues comprised 36% and 45% of our total revenues for the same periods.

     Our software products typically require significant customization,
installation and other services. Prior to the release in July 1999 of Version
4.0 of our application suite, it was difficult to generate dependable estimates
of the costs necessary to complete product implementations. Therefore, we
accounted for our software licenses and implementation revenues using the
completed contract method of contract accounting as required under the
provisions of SOP 97-2 and SOP 81-1, Accounting for Performance of
Construction-Type and Certain Production-Type Contracts.

     Following the release of Version 4.0 in July 1999, we were able to generate
dependable estimates of the costs necessary to complete Version 4.0 product
implementations. Consequently, we are accounting for our Version 4.0 software
licenses and implementation revenues using the percentage-of-completion method
of contract accounting.

     In cases where a sale of a license does not include implementation services
(i.e., a sale of additional seats), revenue is recorded upon delivery with an
appropriate deferral for maintenance services, if applicable.

     We defer amounts billed for maintenance and recognize such amounts ratably
over the maintenance period.

     We have entered into two distribution arrangements under which the
distributors would receive unspecified future products over the life of the
arrangements (two or three years) in consideration for agreed-upon,
non-refundable fees. We recognize such fees ratably, on a subscription basis,
over the life of these related agreements.

     Payments received in advance of revenue recognition are recorded as
deferred revenues. Our deferred revenues balances were $2.5 million and $10.1
million at December 31, 1998 and December 31, 1999. At December 31, 1999, this
deferred revenues balance included $1.4 million of amounts to be recognized
under the completed contract method, which we expect to recognize through the
period ending June 30, 2000, $2.9 million to be recognized under the percentage
of completion method, $1.8 million to be recognized upon delivery of specified
future products, $3.4 million to be recognized under subscription arrangements
and $645,000 to be recognized as maintenance. For the year ended December 31,
1999, we recognized $3.5 million related to contracts accounted for using the
completed contract method, $2.0 million related to contracts accounted for using
the percentage-of-completion method, $330,000 related to sales of additional
business and subscription arrangements and $551,000 recognized as maintenance
revenue. All of our customers enter into one-year maintenance and support
contracts when they purchase their initial Extensity applications and have the
option to purchase additional contracts after completion of the initial contract
period. Although we do not grant any rights to our customers to return products,
we do provide a 90-day warranty that our products will function according to
written documentation.


     We promote and sell our software products through our direct sales force
and through indirect channels, including third-party outsourcers of expense
management services. We also have co-marketing arrangements with a number of
companies including Cisco Systems, First USA, GetThere.com and Netscape.

     In the second quarter of 1999, we expanded our presence in international
markets by opening a sales office in the United Kingdom and by establishing a
relationship with a provider of enterprise financial applications. We hired our
Vice President and General Manager of European Operations in July 1999. We have
continued to hire staff in our United Kingdom office and expect to continue to
do so in advance of anticipated revenues. Hence, we expect our costs for
establishing international sales to exceed related revenues as we invest in
international operations. We have derived no revenues from international sales
to date.

     We have incurred substantial research and development costs since inception
and have more recently invested in our sales and marketing and professional
services organizations in order to support our long-term growth strategy. Our
full-time employees increased from 35 at December 31, 1997 to 83 at December 31,
1998 to 175 at December 31, 1999. As a result of these investments, we have
incurred net losses in each fiscal quarter since inception and, as of December
31, 1999, we had an accumulated deficit of $40.0 million. We anticipate that our
operating expenses will continue to increase as we continue to expand our
product development and sales and marketing efforts. Accordingly, we expect to
continue to incur quarterly net losses for the foreseeable future.

</TABLE>

FISCAL YEARS ENDED DECEMBER 31, 1999, 1998, AND 1997

     Revenues

     Total revenues increased to $6.8 million for the year ended December 31,
1999 from $1.1 million for the year ended December 31, 1998. The 1998 revenues
resulted from licenses and related services for our first product, Extensity
Expense Reports, which was released in March 1998. We did not recognize any
revenues in 1997, as we had not yet released any of our products for commercial
availability. For the year ended December 31, 1998 sales to Scopus Technology,
Baltimore Gas & Electric, Gelco Information Network and Franklin Resources
accounted for 20%, 19%, 14% and 13% of total revenues. For the year ended
December 31, 1999, sales to Sara Lee accounted for 11% of our total revenues.

     LICENSE REVENUES. Our license revenues increased to $3.8 million for the
year ended December 31, 1999 from $718,000 for the year ended December 31, 1998,
an increase of 422%. The increase was attributable to an increase of
approximately 180% in new customers from 1998 to 1999 and to the recognition of
approximately $1.5 million in revenue that was deferred as of December 31, 1998.
The majority of our 1998 customers signed contracts with us in the period from
September to December 1998 and had amounts that were deferred as of December 31,
1998. Approximately 25% of our license revenues in 1999 were attributable to the
recognition of revenues that were deferred as of December 31, 1998.

     SERVICE AND MAINTENANCE REVENUES. Our service and maintenance revenues
increased to $3.1 million for the year ended December 31, 1999 from $409,000 for
the year ended December 31, 1998, an increase of 649%. The increase was
primarily attributable to an

                                       26
<PAGE>   34

increase in the number of new customers in 1999 as compared to 1998, to the
recognition of service revenues deferred as of December 31, 1998, and to a
lesser extent, to increased maintenance and support fees associated with our
increased customer base. As previously mentioned, the majority of our 1998
customers signed contracts with us in the period from September to December 1998
and had amounts that were deferred as of December 31, 1998. Approximately 35% of
our service and maintenance revenues were attributable to revenues that were
deferred as of December 31, 1998. Approximately 20% of the increase in service
and maintenance revenues was attributable to higher maintenance revenues
associated with an increased customer base.

     Cost of Revenues

     Total cost of revenues increased to $5.0 million for the year ended
December 31, 1999 from $1.6 million for the year ended December 31, 1998, an
increase of 201%.

     COST OF LICENSE REVENUES. Cost of license revenues consists primarily of
third-party license and support fees and, to a lesser extent, costs of
duplicating media and documentation. This cost increased to $195,000 for the
year ended December 31, 1999 from $90,000 for the year ended December 31, 1998.
As a percentage of license revenues, cost of license revenues decreased to 5.2%
for 1999 from 12.5% for 1998.

     COST OF SERVICE AND MAINTENANCE REVENUES. Cost of service and maintenance
revenues consists of compensation and related overhead costs for personnel
engaged in consulting, training, maintenance and support services for our
customers as well as costs for third parties contracted to provide such services
to our customers. This cost, net of non-cash stock based compensation of
$344,000 in 1999, increased to $4.8 million for the year ended December 31, 1999
from $1.6 million for the year ended December 31, 1998, an increase of 206%. As
a percentage of service revenues, cost of service revenues decreased from 380%
for 1998 to 155% for 1999. Approximately 60% of the increase in the cost of
service revenues was due to an increase in personnel and approximately 30% was
to due to an increase in costs for third party consultants. These additional
costs were necessary to support our expanding customer base. Total costs have
exceeded our service and maintenance revenues as we have built our consulting
and customer support groups in advance of growing contract volume. Although cost
of service revenues declined as a percentage of service revenues over time, this
cost has continued to exceed the amount of related service revenues. We are
seeking to reduce our cost of service revenues and are also seeking to engage
third parties to provide a substantial portion of services related to our
applications. We expect, however, that cost of service revenues will continue to
exceed service revenues for the foreseeable future. In addition, we have not yet
established significant relationships with any third-party service provider, and
we may not be successful in doing so in the future.

     Operating Expenses

     SALES AND MARKETING. Sales and marketing expenses consist primarily of
compensation and related costs for sales and marketing personnel, including
commissions and marketing program costs. Sales and marketing expenses, net of
non-cash stock based compensation of $989,000 in 1999, increased to $11.2
million for the year ended December 31, 1999 from $4.7 million for the year
ended December 31, 1998, an increase of 138%. Sales and marketing expenses as a
percentage of total revenues were 417% and 164% for the years ended December 31,
1998 and 1999, respectively. Approximately 60% of the increase in sales and
marketing expenses was attributable to increased compensation, commissions and
other related costs associated with hiring additional sales representatives,
management and marketing personnel. Approximately 15% of the increase was due to
increased spending on marketing programs. We expect that the absolute dollar
amount of sales and marketing expenses will

                                       27
<PAGE>   35

continue to increase as we expand our domestic and international sales force and
marketing efforts to capitalize on the growth of our market.

     RESEARCH AND DEVELOPMENT. Research and development expenses consist
primarily of compensation and related personnel costs and fees associated with
contractors. Research and development expenses, net of non-cash stock based
compensation of $1,045,000 in 1999, increased to $7.1 million for the year ended
December 31, 1999 from $4.4 million for the year ended December 31, 1998, an
increase of 60%. Research and development expenses as a percentage of total
revenues were 391% and 103% for the years ended December 31, 1998 and 1999,
respectively. Approximately 65% of the increase was attributable to the addition
of personnel and approximately 25% was due to an increase in consulting
services. These increases resulted as we continued to add enhancements to our
existing software applications and to develop software applications that
incorporate new functionality into an integrated suite. We expect that the
absolute dollar amount of research and development expenses will continue to
increase as we make additional investments in our technology and products.

     GENERAL AND ADMINISTRATIVE. General and administrative expenses consist
primarily of compensation and related costs for our executive, finance and
administrative personnel and other related expenses. General and administrative
expenses, net of non-cash stock based compensation of $1,974,000 in 1999,
increased to $2.8 million for the year ended December 31, 1999 from $1.4 million
for the year ended December 31, 1998, an increase of 102%. Approximately 55% of
the increase was attributable to hiring additional executive and financial
personnel. General and administrative expenses as a percentage of total revenues
were 124% and 41% for the years ended December 31, 1998 and 1999, respectively.
We expect that the absolute dollar amount of general and administrative expenses
will continue to increase as we expand our operations and incur the typical
incremental costs of being a public company.

     Amortization of Non-Cash Stock Based Compensation

     We granted certain stock options to our officers and employees at prices
deemed to be below the fair value of the underlying stock. The cumulative
difference between the fair value of the underlying stock at the date the
options were granted and the exercise price of the granted options was $10.2
million at December 31, 1999. This amount is being amortized, using the multiple
option method, over the four-year vesting period of the granted options.
Accordingly, our results from operations will include deferred compensation
expense at least through 2003. We recognized $4.4 million of this expense during
the year ended December 31, 1999.


     Subsequent to December 31, 1999, we granted options to purchase 461,104 and
157,350 shares of our common stock at exercise prices of $9.00 and $12.00,
respectively. Such grants will result in an additional $1.9 million deferred
compensation charge to be recorded in the first quarter of fiscal 2000.


     Interest and Other Income, Net

     Net interest and other income was $166,000 for the year ended December 31,
1999, and $28,000 for the year ended December 31, 1998. The nominal income for
the year ended December 31, 1998 resulted primarily from the interest generated
from funds raised in the May 1998 private placement of our preferred stock,
partially offset by interest expense from our subordinated debt facility and
capital equipment loans and leases. Interest income for the year ended December
31, 1999 primarily resulted from interest earned on the proceeds from both the
May 1998, July 1999 and December 1999 private placements of our preferred stock,
partially offset by interest expense from these same debt facilities.

INCOME TAXES

     Since inception, we have incurred net losses for federal and state tax
purposes and have not recognized any material tax provision or benefit. As of
December 31, 1999, we had net operating loss carryforwards of approximately
$33.0 million and $18.0 million for federal and state income tax purposes,
respectively. The federal and state net operating loss carryforwards, if not
utilized, expire through 2019 and 2004, respectively. We also have research and
development credit carryforwards of approximately $720,000 and $450,000 for
federal and state tax purposes. Federal and state tax laws impose significant
restrictions on the utilization of net operating loss carryforwards in the event
of a shift in our ownership that constitutes an ownership change, as defined in
Section 382 of the Internal Revenue Code. See Note 4 of Notes to Consolidated
Financial Statements for additional information regarding these carryforwards.

     We have placed a valuation allowance against our net deferred tax assets
due to the uncertainty of the realization of these assets. The allowance totaled
$13.8 million at December 31, 1999, resulting in no net deferred asset. We
evaluate on a quarterly basis the recoverability of net deferred tax assets and
the level of the valuation allowance. When we have determined that it is more
likely than not that the net deferred tax assets are realizable, we will reduce
the valuation allowance.

SEVEN QUARTERS ENDED DECEMBER 31, 1999

  Revenues

     LICENSE REVENUES. Our license revenues have increased in every quarter
following the introduction of our first product in March 1998. These increases
are attributable to the increasing market awareness of the benefits of workforce
optimization software and increasing market acceptance of our solutions. License
revenues in the third and fourth quarters of 1999 increased significantly as we
had established a more visible market presence and expanded our sales and
marketing resources.

     SERVICE AND MAINTENANCE REVENUES. Our service and maintenance revenues have
increased in each quarter in the periods presented, except for the first quarter
of 1999. The generally increasing trend resulted from increases in the number of
installations being completed for our growing customer base, and to a lesser
extent, a growing base of maintenance revenues. The increase in service revenues
on an absolute dollar basis and as a percentage of revenues from the quarter
ended September 30, 1998 to the quarter ended December 31, 1998 resulted from a
higher mix of service revenues for contracts completed in the quarter ended
December 31, 1998 as compared to other quarters. The decrease in service
revenues as a percentage of revenues in the quarter ended September 30, 1999 as
compared to the preceding quarter was due to a lower mix of service revenues for
contracts completed in the quarter ended September 30, 1999 as compared to
previous quarters.

  Cost of Revenues

     COST OF LICENSE REVENUES. Cost of license revenues has fluctuated within a
small absolute dollar range of $9,000 to $77,000 for the seven quarters ended
December 31, 1999. With a more substantial level of license revenues during the
third and fourth quarters of 1999, our cost of license revenues as a percentage
of license revenues was less than 7%.

     COST OF SERVICE AND MAINTENANCE REVENUES. Cost of service and maintenance
revenues, net of non-cash stock based compensation of $0 in 1998 and $27,000,
$50,000, $111,000 and $155,000 for the first, second, third and fourth quarters
of 1999, has increased each quarter in the seven quarters ended December 31,
1999. The increase in cost of service revenues as a percentage of revenues in
the quarter ended March 31, 1999 was attributable to the expansion of our
professional services organization in advance of recognized revenues from
implementations during that period.

  Operating Expenses

     SALES AND MARKETING. Sales and marketing expenses, net of non-cash stock
based compensation of $0 in 1998 and $63,000, $116,000, $256,000 and $554,000
for the first, second, third and fourth quarters of 1999, have increased
steadily since the commercial introduction of our products in March 1998 as we
have continued to build our sales and marketing resources. The primary reasons
for these increases are increased personnel and associated sales commissions,
expanded marketing programs, expansion of regional sales offices and the
addition of an international sales office. Our sales and marketing expenses
decreased slightly to $1.3 million in the first quarter of 1999 from $1.4
million in the last quarter of 1998 due primarily to larger commissions and
bonuses in the fourth quarter of 1998. We expect our sales and marketing
expenses to increase in absolute dollars for the foreseeable future.

     RESEARCH AND DEVELOPMENT. Research and development expenses, net of
non-cash stock based compensation of $0 in 1998 and $99,000, $181,000, $400,000
and $365,000 in the first, second, third and fourth quarters of 1999, continued
to grow during the seven quarters

                                       31
<PAGE>   39

ended December 31, 1999 as we continued to build on our underlying technology
platform, develop new applications and enhance existing applications.

     GENERAL AND ADMINISTRATIVE. General and administrative expenses, net of
non-cash stock based compensation of $0 in 1998 and $126,000, $231,000, $1.2
million and $370,000 in the first, second, third and fourth quarters of 1999
have generally grown consistently during the seven quarters ended December 31,
1999. We have continued to increase the number of general and administrative
personnel to support our growing organization and transaction volume. We expect
general and administrative costs to increase in absolute dollars as we continue
to build the infrastructure necessary to support the growth of our business and
to operate as a public company.

     You should not rely on quarter-to-quarter comparisons of our results of
operations as indicators of future performance due to our limited operating
history, the early stage of our market and the factors discussed in the section
entitled "Risk Factors" above. In particular, because our base of customers and
the number of additional customer licenses we enter into each quarter are still
relatively small, the loss or deferral of a small number of anticipated large
customer orders in any quarter could result in a significant shortfall in
revenues for that quarter. If in some future periods our operating results are
below the expectations of public market analysts and investors, the price of our
common stock may underperform or fall.

LIQUIDITY AND CAPITAL RESOURCES

     Since inception, we have financed our operations and funded our capital
expenditures through the private sale of equity securities, supplemented by loan
facilities and equipment leases. Aggregate net proceeds to date from private
equity financings total $42.3 million. As of December 31, 1999, we had $24.3
million in cash, cash equivalents and short term investments and $13.3 million
in working capital.

     Net cash used in operating activities was $2.5 million in 1997, $8.6
million in 1998 and $11.3 million in 1999. For such periods, net cash used in
operating activities was primarily used to fund ongoing operations including
increases in deferred revenues.

     Net cash used in investing activities was $917,000 in 1997, $6.1 million in
1998 and $9.5 million in 1999. Investing activities consisted primarily of
purchases of short term investments and capital expenditures.

     Net cash provided by financing activities was $6.0 million in 1997, $17.4
million in 1998 and $26.1 million in 1999, and consisted primarily of proceeds
from the issuance of preferred stock and proceeds from loans as offset by
repayments on loans and capital leases. In December 1999, we raised $4.5 million
in proceeds through the private sale of our Series F Preferred Stock. During
1998, we entered into a loan and security agreement with Comdisco Ventures for
$3.5 million and borrowed the total amount. These borrowings bear an average
annual interest rate of approximately 11.4% and are payable in equal monthly
installments through 2001. We have also entered into capital lease agreements
with Comdisco to finance up to $1,850,000 of capital expenditures. Interest
accrues under the terms of these agreements at an average of approximately 7.4%
per annum based on the outstanding utilized capital lease line. Each borrowing
under the capital lease line shall have a term of up to four years, with
interest and principal payable monthly. As of December 31, 1999, we had drawn
approximately $1,748,000 of these lines. We plan to repay all amounts
outstanding under these loans and capital leases with part of the proceeds of
this offering. In connection with these financings, we issued to Comdisco
warrants to purchase a total of 160,303 shares of our Series D Preferred Stock,
each at an exercise price of $3.30 per share, subject to adjustments.

                                       32
<PAGE>   40

     As we execute our strategy, we expect significant increases in our
operating expenses, especially in sales, marketing and engineering. Presently,
we anticipate that our existing capital resources and the proceeds from this
offering will meet our operating and investing needs for at least the next 12
months. After that time, we cannot be certain that additional funding will be
available on acceptable terms or at all. If we require additional capital
resources to grow our business, execute our operating plans, or acquire
complimentary technologies or businesses at any time in the future, we may seek
to sell additional equity or debt securities or secure additional lines of
credit, which may result in additional dilution to our stockholders.

YEAR 2000 COMPLIANCE

     Many currently installed computer systems and software products are coded
to accept only two-digit entries in the date code field and cannot reliably
distinguish dates beginning on January 1, 2000 from dates prior to 2000. Many
companies' software and computer systems have been required to be upgraded or
replaced in order to correctly process dates beginning in 2000.

     ASSESSMENT. We define Year 2000 compliance to mean that systems or products
can accurately process date data from, into and between the years 1999 and 2000,
including leap years, provided that all other products with which they are used,
such as hardware, software, operating systems and firmware, properly exchange
date data with the systems or products.

     We designed all of our products from inception for Year 2000 compliance and
have tested our applications for Year 2000 compliance. We have tested software
obtained from third parties that is incorporated into our applications and
obtained assurances from our vendors that licensed software is Year 2000
compliant. We have received assurances from our vendors of financial systems,
databases, development tools, groupware and hardware systems regarding Year 2000
compliance. We were unable to obtain assurances from the vendor of our customer
support and defect tracking system regarding Year 2000 compliance, but have
performed internal testing and detected no material errors. We have completed
our Year 2000 compliance initiatives and have not become aware of any material
errors in our applications, the third-party software incorporated into our
products or our internal management systems. Moreover, to date we have not
detected any disruptions in our software applications or the software
applications of our software vendors arising from the roll-over to the Year
2000. However, despite our testing and assurances from our vendors, and the lack
of any Year 2000 issues arising from the Year 2000 roll-over to date, we cannot
be certain that our applications or the products we use to run our business do
not contain undetected errors associated with processing date-sensitive data.

     COSTS. We have not incurred any material costs directly associated with
Year 2000 compliance efforts, except for compensation costs for certain
employees who have dedicated time to our assessment of Year 2000 compliance and
associated remedies. We do not expect to incur additional material costs
associated with Year 2000 compliance; however, in the event that we have not
identified and corrected any significant Year 2000 compliance issues, these
unresolved issues could harm our business.

     RISKS. Numerous risks associated with Year 2000 issues could negatively
impact our business. These risks include, but are not limited to:

     - reduced contract sales during first quarter of 2000 as potential or
       existing customers may have been or continue to be focused on remedying
       Year 2000 issues;

     - inability of our products to process date-sensitive information, despite
       our efforts to ensure Year 2000 compliance of our products and despite
       the lack of any Year 2000 issues to date;

                                       33
<PAGE>   41

     - claims from our customers asserting our liability, with potential legal
       costs or settlements, regardless of whether our applications have Year
       2000 compliance issues;

     - diversion of information system, engineering or management resources to
       remedy unanticipated problems that we may detect in the future;

     - undetected management information system failures; infrastructure
       failures, including our phone system; or external system failures,
       including utilities and transportation, that would hinder our operations;
       or

     - damage to our reputation resulting from any of the above.

     The most significant potential adverse situation would include the
inability of our customers to use our products, material legal fees or
settlements, or system failures that disrupt our business.

     CONTINGENCY PLANS. We have not developed contingency plans for the Year
2000 compliance risks previously discussed, either because our assessments have
not detected material issues or because we have not determined cost effective
solutions in light of our assessment of the risks. In the event that we
encounter significant Year 2000 compliance issues for which we have not
developed contingency plans, our business and financial condition could be
materially harmed.

MARKET RISK

     We develop products in the United States and market our products in North
America and, to a lesser extent, in Europe and the rest of the world. As a
result, our financial results could be affected by factors such as changes in
foreign currency rates or weak economic conditions in foreign markets. Because
all of our revenues are currently denominated in U.S. dollars, a strengthening
of the dollar could make our products less competitive in foreign markets.

INTEREST RATE RISK

     We have an investment portfolio of money market funds and fixed income
certificates of deposit. The fixed income certificates of deposit, like all
fixed income securities, are subject to interest rate risk and will fall in
value if market interest rates increase. We attempt to limit this exposure by
investing primarily in short-term securities. In view of the nature and mix of
our total portfolio, a 10% movement in market interest rates would not have a
significant impact on the total value of our portfolio as of December 31, 1999.

     Our interest expense is not sensitive to changes in the general level of
U.S. interest rates because all of our debt arrangements are based on fixed
rates of interest.

                                    BUSINESS

OVERVIEW

     Extensity provides a suite of Internet-based software applications that
automates expense reporting, travel management, procurement and billable time
management for the enterprise employee. These workforce optimization
applications increase employee productivity by streamlining these traditionally
paper-based processes, and enhance operational efficiency by enforcing spending
policies and tracking information that is valuable to management. We have
designed our software from inception to leverage the ease-of-use, accessibility
and open architecture of the Internet. By taking advantage of the Internet as an
application platform, we enable employees to use our applications in their
environment, whether at the office through a networked PC, at home or on the
road through a laptop or with a handheld device, such as a PalmPilot or Visor.
Further, our software design allows our application to be readily integrated
with enterprise resource planning and other information technology systems.

     Since the introduction of our first application in 1998, we have licensed
our applications to 70 customers, the largest of which, based on contract value,
include AirTouch, AT Kearney, BEA Systems, Brigham Young University, Cendant
Business Services, Cisco Systems, Clarify, Documentum, Gelco Information
Network, Genesys Telecommunications, Home Box Office, Sara Lee, Sybase,
TransCanada PipeLines and the University of California. Our customers' employees
constitute a growing network of targeted business users who could benefit from
access to relevant content, commerce and services in completing their daily
tasks associated with expense reporting, travel planning, procurement and time
sheet management. Our objective is to become a leading provider of applications
that optimize an enterprise's workplace and that facilitate exchange between our
customers' employees and third-party content, commerce and service providers. We
refer to this point of exchange as a content and commerce gateway.

INDUSTRY BACKGROUND

     Growth of the Internet as a Platform for Efficient Business-to-Business
E-Commerce

     The Internet has emerged as a universal communications medium and has
become a catalyst for fundamental business change for companies of all sizes.
The efficient, pervasive and interactive nature of the Internet make it a
necessary platform for relevant content exchange and e-commerce transactions
from business to business. Forrester Research estimates that
business-to-business e-commerce will generate $1.3 trillion in revenues by 2003.
In the intensely competitive global business environment, businesses have
increasingly adopted the Internet to streamline their business processes and
make their employees more productive. According to preliminary estimates by
International Data Corporation, the worldwide market for workforce management
applications will grow from $766 million in 1998 to $4.0 billion in 2003, and
the Internet commerce procurement applications market will grow from $147
million in 1998 to $5.3 billion in 2003.

     Traditional Areas of Business Process Automation

     Businesses have traditionally made significant investments in ERP and other
enterprise software applications to automate processes in functions such as
manufacturing, sales, human resources and finance. These systems typically have
been focused on specific individual functional areas and only address the
business processes unique to each functional area. Also, they offer limited
integration of information across functional areas. These systems have been
significantly limited in their ability to integrate information external to the
enterprise. ERP and other enterprise software systems have also traditionally
required lengthy and expensive customization and implementation and are
expensive to maintain because their client-server

                                       35
<PAGE>   43

architecture requires installation and continued maintenance on each desktop.
While these systems are in place in many companies, they have not focused
historically on certain pervasive business processes, such as expense reporting,
travel management, procurement and billable time management, which touch large
numbers of employees in any organization.

     These employee-centric business processes have been left largely
unautomated to date, resulting in processes that are time-consuming, inefficient
and costly. Most organizations today conduct travel expense, procurement and
billable time management through paper-based processes that require actions by
many individuals both inside and outside the enterprise. These processes involve
re-keying of data, manual tracking of forms, limited data capture and reporting,
and limitations on the ability to track and enforce corporate spending policies.
Without business process automation, expense reporting, procurement and time
management transactions can have significant processing costs. For example,
American Express has estimated that the average company spends $36 to process an
expense report using traditional paper-based methods. In addition, traditional
processes do not generally feature automated spending and procurement controls
and, as a result, may fail to direct spending to preferred vendors and may
permit spending on unapproved goods and services. The inefficiencies associated
with traditional processes can involve significant total cost, as operating
resource expenditures typically represent 33% of a company's total costs,
according to Killen & Associates.

     Opportunity for Workforce Optimization Applications

     A significant market opportunity exists for workforce optimization
applications that streamline processes within the organization and across the
extended enterprise and provide integrated access to third-party content,
commerce and services. At the same time, the rapid adoption of the Internet by
businesses has radically changed the business environment. The growth of the
Internet in conjunction with increasing business globalization and technological
advancements has increased competitive pressures for all businesses by lowering
barriers to market entry, rewarding innovative business models and providing an
easily accessible commerce channel over the Internet. Accordingly, the rapid
growth of the Internet has both enabled the introduction of Internet-based
workforce optimization solutions and made their adoption a strategic imperative.

     A comprehensive workforce optimization solution must provide benefits
inside and outside a business organization, to employee users, business managers
and third-party content, commerce and service providers. Such a solution must:

     - give companies a highly scalable, easily implemented and widely
       accessible set of applications that streamlines workforce processes by
       linking employees, approvers and administrative personnel;

     - reduce the time employees spend on general workforce management tasks,
       freeing them to focus on their core responsibilities;

     - provide data to business managers for contract negotiation and for
       enforcing discounts with preferred vendors;

     - provide business managers with information on individual employee and
       overall workforce utilization, in order to better manage employee
       productivity and profitability;

     - enable business administrators to enforce policies actively and
       efficiently; and

     - provide an end-to-end solution by connecting the employee to third-party
       content, commerce and service providers over the Internet.

                                       36
<PAGE>   44

     A comprehensive workforce optimization solution should benefit both
employees and third-party providers by directing information, services and
focused commerce opportunities to employees while delivering valuable business
customers and business spending to participating providers. We refer to this
integrated point of exchange between employees and third-party providers as a
content and commerce gateway.

THE EXTENSITY SOLUTION

     We provide an integrated suite of Internet-based, workforce optimization
software applications designed to improve the productivity of employees across
the enterprise and to enhance enterprise operating efficiency. Our Extensity
Application Suite currently includes applications for expense reporting,
business travel, procurement and billable time management. In addition, our
solution can leverage the Internet to serve as a gateway between employees and
third-party content, commerce and service providers through buying exchanges,
online marketplaces, specialized portals and supplier sites. We believe our
solution makes our customers' employees more productive and companies more
efficient, while providing better information to management.

     The Extensity Application Suite

     Our application suite is currently comprised of the Extensity Expense
Reports, Extensity Travel Plans, Extensity Timesheets and Extensity Purchase
Reqs applications and the Extensity System Administration Tool. The application
suite is fully integrated so that each application works with and shares
information with all the other applications. In addition, our applications
aggregate and integrate information for management reporting and analysis. Our
applications are easy to learn for the user, as users can access all

     Our workforce optimization solution provides direct and indirect cost
savings by:

     - streamlining and automating traditional paper-based processes, thereby
       reducing the time and personnel requirements associated with processing
       expense reports, travel plans, purchase requisitions and timesheets;

     - increasing accuracy through automation of error-checking, data import and
       business rule compliance;

     - providing greater control of expenditure policy administration and
       enforcement;

     - supporting analysis of business purchasing and utilization patterns to
       enhance decision-making capabilities and to increase leverage in
       negotiating vendor and service provider contracts; and

     - promoting and enforcing the use of preferred vendors.

                                       37

     Our workforce optimization solution also increases productivity throughout
the enterprise by:

     - reducing employee time spent on tasks outside of their core
       responsibilities;

     - providing a consistent, intuitive, browser-based user interface to all
       applications;

     - supporting remote access via Palm Pilot and other mobile computing
       devices; and

     - enabling exception-based management that allows business managers to
       review only those expenditures which fall outside of a company's
       policies.

     The Extensity Partner Network

     We have recently begun to develop our Extensity Partner Network to
establish an Internet gateway between a company's workforce and third-party
content, commerce and service providers. We believe this network will benefit
both our customers' employees and third-party providers by directing relevant
information, services and focused commerce opportunities to our customers'
employees while delivering valuable business customers and spending to
participating providers.

     We will continue to develop this gateway to provide benefits to employees
and third-party providers by:

     - providing users with seamless, integrated access to relevant content,
       services and e-commerce capabilities;

     - delivering to our partners access to a network of employees that are
       likely to engage in specific commercial transactions;

     - reducing transaction costs to both our customers' employees and content,
       commerce and service providers by utilizing the Internet to enhance
       information flow; and

     - enabling open access to multiple online markets to minimize reliance on a
       single marketplace.

     As more companies implement our solution, the Extensity network of our
customers' employees continues to grow. We believe that this network of
employees will become a valuable aggregated base of potential customers for
additional third-party content, commerce and service providers. As these
providers offer additional products and services through our network, customers
are encouraged to join, establishing a cycle that increases the value of the
Extensity solution to both our customers and third-party providers.

EXTENSITY STRATEGY

     Our objectives are to gain broad market acceptance of our workforce
optimization applications and to build the largest Internet-based network of
organizations and employees. By building this network, we plan to become the
leading content and commerce gateway for the enterprise workforce. This will
allow our partners and us to deliver valuable content and business-to-business
services to our growing network.

     Key elements of our growth strategy include:

          EXPANDING OUR WORKFORCE OPTIMIZATION SOLUTIONS. We intend to continue
     to enhance the Internet-based architecture of our technology platform in
     order to provide a comprehensive, functionally-rich solution for
     employee-centric business processes. We also intend to continue to enhance
     the functionality of our existing application suite and, by leveraging the
     existing platform, to introduce additional integrated workforce
     optimization applications.

          AGGRESSIVELY PENETRATING THE LARGE AND UNTAPPED WORKFORCE OPTIMIZATION
     MARKET. We believe that the market for automated workforce optimization
     solutions is large and underpenetrated for enterprises of all sizes. In
     order to address this market opportunity, we intend to aggressively expand
     our direct and indirect sales channels. We plan to focus our direct sales
     efforts on large multinational organizations across a variety of
     industries. In addition, we plan to address small and mid-size
     organizations through a combination of telesales and relationships with
     application service providers, OEMs and other resellers.

          STRENGTHENING INTERNATIONAL PRESENCE THROUGH STRATEGIC PARTNERSHIPS
     AND DIRECT DISTRIBUTION. We plan to capitalize on international market
     opportunities by establishing additional international sales offices,
     expanding our international direct sales force and building strategic
     overseas partnerships. We will continue to staff our international
     organization with senior local management and experienced domestic
     management with specific product and market expertise. Our application
     suite is internationalized and we plan to localize it for certain European
     languages during 2000.

          INCREASING MARKET ADOPTION THROUGH STRATEGIC PARTNERSHIPS WITH
     APPLICATION SERVICE PROVIDERS. Because customers are increasingly utilizing
     application service providers to host or outsource their applications, we
     intend to partner with application service providers as an additional
     indirect sales channel. We believe that our readily-implemented,
     Internet-based architecture and easy-to-learn end-user solution is
     attractive to application service providers. We currently have two
     application service provider partners, Gelco Information Network and
     Cendant Business Services, and intend to develop strategic relationships
     with others.

          OFFERING A SINGLE GATEWAY FOR THE MOST COMPREHENSIVE NETWORK OF
     EXTERNAL CONTENT, COMMERCE AND SERVICE PROVIDERS. Our applications are
     designed to provide a single, Internet standards-based point of access, or
     gateway, for online providers of indirect goods and services, including
     travel and entertainment, office equipment and supplies, professional
     services, information and technology equipment, and other repeat purchase
     items. This gateway will give our customers flexibility in the suppliers
     with which they choose to integrate, without requiring point-to-point
     integration or a commitment to a proprietary single solution. We believe
     our gateway will provide to our customers a superior e-commerce solution as
     online transactions gain market acceptance and as online vertical
     marketplaces emerge.

          EXTENSITY EXPENSE REPORTS. Extensity Expense Reports is a
     full-featured application providing automation of the entire expense
     reporting process. Extensity Expense Reports brings accuracy, efficiency
     and control to this process. Using Extensity Expense Reports, employees,
     whether operating as a remote, off-line or local user, can quickly and
     easily create an expense report. This process is expedited and made more
     accurate through the use of online credit card data for automatic data
     entry. Compliance to business policy is checked as the expense report is
     created. Compliant reports can be automatically approved, and only
     noncompliant reports are routed to managers for approval. In reviewing
     noncompliant reports, managers need only focus on highlighted exceptions.
     Re-keying data and auditing of expense reports are reduced or eliminated so
     the accounting team can spend time analyzing the centralized travel and
     entertainment expense data and leveraging that knowledge into cost savings.
     Employees can receive reimbursement rapidly through seamless integration
     with the organization's financial, payroll and human resources systems.

     Customer case studies

          BESTFOODS. International food giant Bestfoods, with revenue of $8.4
     billion, uses our applications to streamline its travel expense reporting
     and automatically enforce corporate travel expense policies. In North
     America, Bestfood's 3,000 regular travelers generate over 68,000 expense
     reports each year. In 1998, Bestfoods began to evaluate several Internet-
     based software applications to implement on its worldwide corporate
     intranet, including expense report applications. After evaluating several
     expense reporting applications, Bestfoods selected Extensity because of its
     web-based solution and high ratings from its user panel. Bestfoods chose
     Extensity Expense Reports in November 1998, re-engineered its expense
     reporting procedures and began to deploy our application to its U.S. users
     in May 1999.

          By using Extensity Expense Reports, Bestfoods can now reimburse
     employees within three days of travel and enforces Bestfood's travel and
     expense policies in a less intrusive way. Bestfoods integrates Extensity
     Expense Reports with American Express, allowing traveling employees to
     automatically download their receipts from American Express on a daily
     basis, fill out their reports and submit them without waiting for monthly
     credit card statements to arrive by mail. Using Extensity business rules,
     the application is set up to authorize expenses within certain parameters.
     If the report falls within those guidelines it is automatically approved by
     the system and managers only need to review expense reporting exceptions.
     Because employees are reimbursed within two to three days, Bestfoods is
     able to eliminate most travel advances and a significant amount of
     accounting overhead. Bestfoods also uses the reporting capabilities to
     minimize re-keying of data and auditing of

                                       44
<PAGE>   52

     expense reports, so it can spend time analyzing travel and entertainment
     data and leverage that knowledge into cost savings.

          EXCITE@HOME. Excite@Home is a leading provider of broadband Internet
     services over the cable television infrastructure. One of Excite@Home's key
     operational goals is to implement best practices and eliminate paper-based
     processes across its organization. In March 1998, Excite@Home selected
     Extensity Expense Reports to manage travel, entertainment and other
     corporate expenses. Prior to the merger with Excite, @Home had its employee
     base on the Extensity applications. As the two companies continue to
     integrate their systems, all Excite@Home employees will become users of the
     Extensity application. Excite@Home currently has 500 employees on the
     Extensity system. By using our application, Excite@Home has been able to
     process more than twice the volume of expense reports in half the time
     without increasing its accounting staff. Excite@Home is integrating its
     accounting system with Extensity for seamless information flow and plans to
     implement direct deposit capabilities to further remove paper from its
     workforce processes. Due to our database approach, finance personnel can
     query their centralized database using their standard tools and can gather
     valuable information for consolidation and budgeting. This analysis has
     proven to be extremely valuable in negotiations with airline and lodging
     vendors.

TECHNOLOGY

     Our applications are fully standards-based, designed for the Internet and
built upon an underlying architecture that is written entirely in Java. Our
applications run on standard Web browsers and servers and support leading
relational database management systems (RDBMS), including Oracle, Sybase and
Microsoft SQL Server. The multi-tier architecture connects browser-based
applications to application servers and the RDBMS through a corporate local area
network (LAN), wide area network (WAN), intranet or a secure Internet
connection. Our technology performs messaging between clients and the
application engine in real time over TCP/IP, and makes database connections via
standard Java database drivers. Our applications are inherently scalable, due to
our multi-tier architecture employing thin clients, multi-threaded application
servers and relational databases. In addition, our Java-based architecture
enables the Extensity Application Suite to operate across multiple platforms
within any organization, including Windows 95, 98 or NT, Macintosh, Solaris and
Palm Pilot operating systems.

     The Extensity Architecture

     Building on a standards-based foundation, we have designed a
component-based application infrastructure composed of readily-configurable
business rules, a workflow system and advanced data management capabilities.
Each of these core elements plays a crucial role in deploying enterprise-wide
solutions that can model a company's unique policies and processes and manage
key business functions.

     The following diagram illustrates the multi-tiered architecture of our
software applications, the use of the Internet for deployment and the
relationship of the application server to our other application components.

                                [EXTENSITY LOGO]

          BUSINESS RULES SYSTEM. Our business rules system allows each Extensity
     application to be configured so that companies can effectively monitor
     their processes and policies. This system is also flexible and can be
     edited and modified as a company's processes and policies evolve. Employees
     are presented with appropriate warnings, explanations and message prompts
     to guide data entry and encourage conformance with corporate policies. The
     business rules dramatically reduce reworking of procedures, track and
     resolve policy exceptions online and eliminate re-keying of data into
     back-end systems. The business rules system permits management by
     exception, in which items requiring managerial attention are automatically
     highlighted so that managers need not review items that are clearly in
     compliance with established business rules.

          WORKFLOW SYSTEM. Our workflow system ensures that information flows
     through the organization in a timely, secure and efficient manner. Robust
     enterprise applications require database-driven workflow, rather than
     e-mail-based messaging, to provide increased

                                       46
<PAGE>   54

     security and reliability, data and transaction integrity, real-time
     availability, optimization for high performance and usage reporting.
     Workflow processes can be configured to reflect the unique process flow of
     documents and business processes in any organization. Our applications also
     permit e-mail notification to users of the status of a procedure or of
     events requiring attention, alteration and action, such as notifying the
     creator of an expense report of its location in the process cycle or
     notifying a manager of a document requiring attention.

          ADVANCED DATA MANAGEMENT. Data management ensures that all Extensity
     applications can be customized and extended to add, delete or modify
     buttons, type-in fields or other controls on an application's user
     interface, in each case as required by a customer's unique business
     objectives. New functionality can also be assigned to existing controls, or
     new controls, with little application modification and minimal programming.
     The Extensity Application Suite can integrate with enterprise systems such
     as ERP systems and other financial, human resources (for user information
     and organizational structure) and project accounting systems and corporate
     credit card systems. These interfaces allow for the automatic exchange of
     data between the Extensity system and other enterprise systems and for the
     downloading of data managed by these enterprise systems into the Extensity
     application suite. These integration processes are scheduled according to
     the needs of our customer's information services and finance departments.

STRATEGIC RELATIONSHIPS

     To rapidly deliver a comprehensive, robust solution to our customers, we
have established strategic relationships with companies in three general
categories: e-business providers; content, commerce and service providers; and
marketing and distribution partners.

     E-BUSINESS PROVIDERS. We have established relationships with key solutions
providers to deliver integrated workforce optimization solutions to our
customers. Cisco Systems has selected Extensity as one of four solutions
providers to support its workforce optimization effort. We have an agreement
with Cisco that establishes Extensity as Cisco's strategic Internet business
solutions software partner and Cisco as Extensity's strategic networking
partner. This relationship includes a mutual agreement to integrate each party's
sales and marketing plans and obligates each party to review the other party's
respective architectures for possible product integration. In this initiative,
Cisco has taken an active role in communicating to its customers the benefits of
Extensity Expense Reports. Cisco also supports Extensity through sales
assistance, customer referrals and co-marketing activities. In the procurement
card market, we work with American Express to integrate the Extensity
Application Suite with the American Express Procurement card. We have agreed to
a product integration workplan with American Express, which enhances the quality
of integration for our customers. We are also a strategic partner with IBM, a
leader in defining e-business in the marketplace. We have a marketing agreement
with IBM that is designed to ensure compatibility of our complementary
solutions. This agreement obligates Extensity to support IBM's DB2 database, and
obligates IBM to pay a marketing fee to Extensity for agreed upon marketing
activities.

     CONTENT, COMMERCE AND SERVICE PROVIDERS. We have formed strategic
relationships with several content, commerce and service providers to allow our
network of customer employees to conduct commerce efficiently over the Internet.

Online, Sabre BTS and Rosenbluth International and a joint marketing arrangement
in place with Visa International.

MARKETING AND SALES

     We focus our marketing efforts on achieving brand recognition, market
awareness and lead generation. The market for our Extensity Application Suite
includes enterprises of all sizes in many industries. We typically market to the
senior financial officer in an organization, such as the Chief Financial Officer
or Vice President of Finance. We also conduct public relations campaigns to keep
the market aware of our product developments and major initiatives. Programs we
use to attract customers include advertising in business and financial
publications, trade shows, seminars, and direct mail. We also participate in
various co-marketing initiatives with strategic partners. We maintain close
relationships with industry analysts and frequently participate in industry
conferences and events. Our website serves as another sales tool for prospective
customers.

                                       48
<PAGE>   56

     We sell our Extensity Application Suite primarily through our direct sales
organization. Our U.S. sales force is organized under three regional directors
and a Vice President of Sales. We have sales offices in Boston, Chicago,
Emeryville, CA, London, Los Angeles and Mahwah, NJ. Our U.S. sales organization
included 21 direct sales representatives as of December 31, 1999. Our direct
sales representatives are supported by field-based sales engineers and sales
development staff. Our European sales organization includes a general manager,
two sales professionals and a marketing manager.

PRODUCT DEVELOPMENT

     We have been developing and enhancing the Java-based architecture of our
applications for the Internet since 1996. We released our first Extensity
application, Extensity Expense Reports, in March 1998. Extensity Expense Reports
was one of the first workforce optimization applications to be architected
specifically for the Internet. We introduced Extensity Travel Plans in December
1998 and Extensity Timesheets and Extensity Purchase Reqs in July 1999. These
four applications, together with the Extensity System Administration Tool,
comprise our Extensity Application Suite, Version 4.0.

     As of December 31, 1999, our engineering organization consisted of 53
employees and is grouped according to the following areas of focus: product
development, core technology, release engineering, mobile engineering,
architecture, tools development, quality assurance and technical documentation.
Each group within Extensity's engineering organization regularly shares
resources and collaborates with other groups on code development, quality
assurance and documentation. Our engineering organization includes a number of
key individuals that have developed Internet applications and services and have
extensive experience with Java-based application development. We believe that a
technically skilled and experienced engineering organization is a key factor in
the market acceptance of our applications and, accordingly, we plan to continue
to make significant investments in our engineering organization and efforts to
promote the success of our products. If we are unsuccessful in hiring and
training a sufficient number of personnel to staff our engineering organization,
our business could suffer.

     To date, we have made significant investments in our technology
architecture and applications, and we believe they provide us with a significant
competitive advantage. Our research and development expenses totaled $7.1
million in 1999, $4.4 million in 1998 and $1.7 million in 1997. We intend to
maintain our competitive advantage by continuing to focus on and refine our
development efforts. Our engineering organization employs a defined product
development methodology to each application, which includes technology and
architectural roadmaps, product planning, requirement specifications,
prototyping, design specifications, code review, identified program review
points and beta testing.

     To successfully implement our business strategy, we have to provide
software applications and related services that meet the demands of our
customers and prospective customers. We expect that competitive factors will
create a continuing need for us to improve and add to our suite of software
solutions. We will have to, among other things, expend significant funds and
engineering and other resources to continue to improve our suite of
applications, and properly anticipate and respond to consumer preferences and
demands. As organizations' needs change with respect to their enterprise
applications, our existing suite of software applications may require
modifications or improvements. The addition of new products and services will
also require that we continue to improve the technology underlying our
applications. These requirements are significant, and we may fail to execute on
them quickly and efficiently. If we fail to expand the breadth of our
applications quickly in response to customer needs, or these offerings fail to
achieve market acceptance, our business will suffer significantly.

COMPETITION

     The markets for Internet-based workforce optimization applications are
intensely competitive, and we expect the intensity of competition to increase in
the future. Increased competition may result in price reductions, reduced
margins and loss of market share, any one of which could seriously harm our
business. Competitors vary in size and in the scope and breadth of the products
and services offered. Companies offering one or more products directly
competitive with our products include Ariba, Captura Software, Concur
Technologies and IBM. We also expect to encounter competition in the near future
from major enterprise software vendors such as Oracle Corporation, PeopleSoft
Corporation and SAP Corporation, to the extent they enhance their existing
product offerings with competitive workforce optimization applications. As a
result of the large market opportunity, we also expect competition from other
established and emerging companies. For example, as the emergence of the ASP
market enables hosted solutions from our competitors to become broadly
available, our future success may also depend upon our ability to establish
successful relationships with leading ASPs.

     We believe that the key competitive factors affecting our market include a
significant base of reference customers, breadth and depth of products and
product features, product quality and performance, core technology underlying
our applications, customer service and ability to rapidly implement our
solutions. We believe that our workforce optimization applications currently
compete favorably with respect to these factors. However, because the market for
our solutions is at an early stage of development and evolving rapidly, we
cannot assure you that we will be able to maintain our competitive position
against our current and potential competitors, particularly those with greater
financial, marketing, technical service and other resources.

     Many of our current and potential competitors have longer operating
histories, significantly greater financial, technical, marketing and other
resources, significantly greater name recognition and a larger installed base of
customers than us. In addition, many of our competitors have well-established
relationships with our current and potential customers and have extensive
knowledge of our industry. Moreover, current and potential competitors have
established or may establish cooperative relationships among themselves or with
third parties to increase the ability of their products to address customer
needs. Accordingly, it is possible that new competitors or alliances among
competitors may emerge and rapidly acquire significant market share. We also
expect that competition will increase as a result of industry consolidations. We
may fail to successfully compete against our current and future competitors.

INTELLECTUAL PROPERTY RIGHTS

     Our success depends in large part upon our proprietary technology. We rely
on a combination of copyright, trademark and trade secret protection,
confidentiality and nondisclosure agreements and licensing arrangements to
establish and protect our intellectual property rights. We license rather than
sell our solutions and require our customers to enter into license agreements,
which impose restrictions on their ability to utilize the software. In addition,
we seek to avoid disclosure of our trade secrets through a number of means,
including requiring those persons with access to our proprietary information to
execute nondisclosure agreements with us and restricting access to our source
code. We seek to protect our software, documentation and other written materials
under trade secret and copyright laws, which afford only limited protection.

     We currently have no patents, although we have filed eight provisional
patent applications with the U.S. Patent and Trademark Office relating to
various features and processes embodied in our applications. A provisional
patent application is a type of application under which a patent will not issue,
but which provides a priority date for a regular patent application that is
filed within a one year period following the filing of the provisional patent
application. We cannot assure you that any regular patents will be filed based
on our provisional applications, or that

                                       50
<PAGE>   58

any patents will issue on our pending provisional applications from any such
regular applications. Further, we cannot provide any assurance that any patents,
if issued, will prevent the development of competitive products or that our
patents will not be successfully challenged by others or invalidated through
administrative process or litigation.

     Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy aspects of our products or to obtain and use information
that we regard as proprietary. Policing unauthorized use of our products is
difficult, and while we are unable to determine the extent to which piracy of
our software products exists, software piracy can be expected to be a persistent
problem. In addition, the laws of some foreign countries do not protect our
proprietary rights to as great an extent as do the laws of the United States.
Our means of protecting our proprietary rights may not be adequate and our
competitors may independently develop similar technology, duplicate our products
or design around our proprietary intellectual property.

     There has been a substantial amount of litigation in the software industry
and the Internet industry regarding intellectual property rights. It is possible
that in the future, third parties may claim that we or our current or potential
future products infringe upon their intellectual property. We expect that
software product developers and providers of Internet-based software
applications 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, with or without
merit, could be time consuming, result in costly litigation, cause product
shipment delays or require us to enter into royalty or licensing agreements.
Royalty or licensing agreements, if required, may not be available on terms
acceptable to us or at all, which could seriously harm our business.

EMPLOYEES

     As of December 31, 1999, we had a total of 175 employees, including 53 in
research and development, 64 in sales and marketing and business development, 37
in professional services and 21 in finance and administration. None of our
employees are subject to a collective bargaining agreement and we believe our
relations with our employees are good.

FACILITIES

     Our primary administrative, sales, marketing, research and development
facility is located in Emeryville, California and consists of approximately
24,000 square feet of office space held under a lease that expires in June 2003.
As of December 31, 1999, we also leased sales offices in Boston, Chicago,
London, Los Angeles and Mahwah, NJ. We believe our existing facilities meet our
current needs and that we will be able to obtain additional commercial space as
needed.

LEGAL PROCEEDINGS

     Although we are not currently a party to any litigation, we may from time
to time become involved in litigation relating to claims arising from our
ordinary course of business. These claims, even if not meritorious, could result
in the expenditure of significant financial and managerial resources.

BOARD OF DIRECTORS


     Our board of directors is currently comprised of seven directors. In
October 1999, the board of directors designated a Compensation Committee and an
Audit Committee. Prior thereto, there were no such committees of the board of
directors, and decisions regarding the compensation of executive officers were
made by the board of directors as a whole. The Compensation Committee, which
consists of Messrs. Hummer, Kertzman and Schlein, makes recommendations to the
Board concerning the compensation of our officers and directors and the
administration of our 1996 Stock Option Plan and Employee Stock Purchase Plan
2000. The Audit Committee, which consists of Messrs. Hummer, Kertzman and
Schlein, reviews our financial controls, evaluates the scope of the annual
audit, reviews audit results, consults with management and our independent
auditors prior to the presentation of financial statements to stockholders and,
as appropriate, initiates inquiries into aspects of our internal accounting
controls and financial affairs.


DIRECTOR COMPENSATION


     Directors currently do not receive any cash compensation from Extensity for
their services as members of the board of directors, although members are
reimbursed for expenses in connection with attendance at board of directors and
committee meetings. Directors are eligible to participate in Extensity's stock
plans. On August 20, 1998, Mr. Kertzman was granted an option to purchase
100,000 shares of common stock at an exercise price of $0.33 per share, pursuant
to the 1996 Stock Option Plan. On November 18, 1999, Maynard Webb was granted an
option to purchase 50,000 shares of common stock at an exercise price of $6.00
per share, pursuant to the 1996 Stock Option Plan. On January 17, 2000, each of
Messrs. Brennan, Hummer and Schlein was granted an option to purchase 50,000
shares of common stock at an exercise price of $9.00 per share. Option grants to
directors are at the discretion of Extensity, and we have no specific plans
regarding amounts to be granted to our directors in the future.


COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The Compensation Committee currently consists of Messrs. Hummer, Kertzman
and Schlein. Prior to the formation of the Compensation Committee, the board of
directors performed the functions typically assigned to a compensation
committee. Each of Mr. Sasson and Mr. Spinner participated in the board's
deliberations concerning compensation of officers other than themselves. No
member of the Compensation Committee and none of our executive officers has a
relationship that would constitute an interlocking relationship with executive
officers and directors of another entity.

     Hummer Winblad Venture Partners and its affiliated funds collectively have
purchased an aggregate of 3,931,891 shares of our series A through E preferred
stock for an aggregate of $9,214,617. One of our directors, John R. Hummer, is a
managing member of Hummer Winblad Venture Partners.

     Kleiner Perkins Caufield & Byers and its affiliated funds have collectively
purchased an aggregate of 2,909,040 shares of our series B through E preferred
stock for an aggregate of $6,249,982. One of our directors, Ted E. Schlein, is a
general partner of Kleiner Perkins Caufield & Byers.

                                       55
<PAGE>   63

     Upon the closing of this offering, each outstanding share of series A, B,
C, D and E preferred stock will convert into one share of common stock.

     We have entered into indemnification agreements with our officers and
directors, including Messrs. Hummer, Kertzman, Schlein, Sasson and Spinner.
These indemnification agreements contain provisions that may require us, among
other things, to indemnify our officers and directors against certain
liabilities that may arise by reason of their status or service as officers or
directors.

     We entered into an offer letter with Robert Spinner, our President and
Chief Executive Officer on February 16, 1999. Pursuant to his offer letter Mr.
Spinner is entitled to an initial annual base salary of $300,000 and up to
$100,000 in performance bonuses based upon satisfaction of agreed upon
milestones. However, Mr. Spinner elected to reduce his initial annual base
salary to $275,000 effective June 16, 1999 and declined an initial $50,000 bonus
to which he was otherwise entitled payable in November 1999. Pursuant to the
offer letter, Mr. Spinner was granted (1) an option to purchase 1,188,764 shares
of common stock, subject to vesting over a four year period, and (2) a special
option to purchase an additional 77,306 shares of common stock vesting on March
1, 2006 or sooner if milestones set by the board relating to his performance are
achieved. Each option has an exercise price of $0.33 per share. In the event
that Extensity terminates Mr. Spinner's employment other than for cause or Mr.
Spinner's employment is constructively terminated, then Mr. Spinner is entitled
to receive severance payment equal to six months' continuation of salary. In
addition, in the event that Extensity involuntarily terminates Mr. Spinner's
employment within one year following a change of control of Extensity, Mr.
Spinner is entitled to accelerated vesting of one half of the portion of the
option to purchase 1,188,764 shares of common stock that is otherwise unvested
on the date of termination.

     We entered into a loan agreement with Mr. Spinner on March 12, 1999.
Pursuant to this agreement, Mr. Spinner was loaned an aggregate of $100,000 in
order to early exercise 303,030 shares of common stock which were granted to him
under his offer letter. In connection with this loan, Mr. Spinner executed a
promissory note in favor of Extensity. The promissory note bore interest at a
rate of 4.77%, compounded semi-annually, was to mature on February 28, 2004 and
was secured by a pledge of the common stock purchased by Mr. Spinner for cash,
under the terms of a security agreement between Mr. Spinner and Extensity. Mr.
Spinner repaid this loan in full, including interest of $3,081, on November 9,
1999. Mr. Spinner also early exercised at such time 454,576 shares for an
aggregate of $150,000 in cash.

</TABLE>

     The 0%, 5% and 10% assumed annual rates of compounded stock appreciation
are mandated by the rules of the Securities and Exchange Commission based on the
deemed value of the common stock used by us for accounting purposes and do not
represent our estimate or projection of our future stock prices. Actual gains,
if any, on stock option exercises will be dependent on the future performance of
our common stock. The amount shown in the "0%" column reflects the difference
between the exercise price and the deemed fair market value as of the date of
option grant. All options were granted at an exercise price which our board of
directors believed to be equal to the fair market value of our common stock on
the date of grant. Based upon a subsequent review, we determined that the fair
value of the common stock as of the date of grant would be deemed for financial
accounting purposes to be the number indicated in the "Deemed Fair Market Value
on Date of Grant" column. In such subsequent determination of the deemed fair
market value, we considered, among other things, valuations at which we have
issued our preferred stock, the relative rights and preferences of our preferred
stock as compared to our common stock, estimated discounts from our preferred
stock valuations, the stability and tenure of our management team, the
development and size of the market for our products, and the offering price to
the public in this offering.

     Except for options granted to Mr. Spinner, all options indicated in the
table above have a ten year term, vest as to 25% of the shares one year from the
vesting commencement date and vest at the rate of 1/48 of the shares at the end
of each month thereafter, subject to continued service as an employee or
consultant. Our board of directors has permitted Robert Spinner, Elizabeth
Ireland, Allen Nordgren and Eric Ruud to exercise these options prior to vesting
in exchange for shares of restricted common stock. We have a right to repurchase
all unvested shares of restricted stock if executive officers are terminated for
any reason. The repurchase right must be exercised by us within ninety days of
termination of the executive officer. Our repurchase right lapses on the same
terms as the option vesting period discussed above.

     In February 1999, Extensity granted to Mr. Spinner an option to purchase
1,188,764 shares of common stock, which vested as to 12.5% on September 1, 1999
and vest as to 1/48 of these shares on each month thereafter, so that all of
these shares are fully vested and exercisable on the fourth anniversary of the
vesting commencement date. Extensity also granted Mr. Spinner at such time an
option to purchase an additional 77,306 shares of common stock.

                                       58
<PAGE>   66

These shares vest in full on March 1, 2006, provided that if the board of
directors determines that Mr. Spinner has achieved performance milestones
specified for his first year as Chief Executive Officer of Extensity, then these
shares shall vest in accordance with the same schedule as Mr. Spinner's option
to purchase 1,188,764 shares of common stock. For additional details on Mr.
Spinner's employment agreement, see "Compensation Committee Interlocks and
Insider Participation."

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

     The following table sets forth information concerning option exercises and
unexercised options for the fiscal year ended December 31, 1999 with respect to
each of the named executive officers.

     The value realized represents the difference between the deemed value of
the common stock on the date of exercise used by us for accounting purposes and
the exercise price of the option.


     The value of unexercised in-the-money options was calculated by determining
the difference between $17.00 (the assumed initial public offering price) and
the exercise price of the option.

COMPENSATION PLANS

  1996 STOCK OPTION PLAN

     Extensity's 1996 Stock Option Plan provides for the granting to employees
of incentive stock options within the meaning of Section 422 of the Internal
Revenue Code of 1986, as amended (the Code), and for the granting to employees,
directors and consultants of nonstatutory stock options and stock purchase
rights (SPRs). The 1996 Option Plan was approved by the board of directors in
February 1996 and by the stockholders in February 1996. Unless terminated
sooner, the 1996 Option Plan will terminate automatically in 2006. A total of
6,100,000 shares of our common stock is currently reserved for issuance pursuant
to the 1996 Option Plan. In October 1999, our board of directors approved an
amendment, subject to stockholder approval, to amend the 1996 Stock Option Plan
to increase the maximum number of shares issuable under the plan to 7,000,000.
This amendment will be effective at the completion of this offering. The
following discussion reflects additional changes to the Plan made by such
amendment. In addition, the 1996 Option Plan provides for automatic annual
increases in the number of shares reserved for issuance under the plan, in an
amount each year equal to the lesser of (1) 4% of the outstanding shares on such
date, (2) 1,300,000 shares and (3) such lesser amount as may be determined by
the board.

     The 1996 Option Plan may be administered by the board of directors or a
committee of the Board (as applicable, the Administrator), which shall, in the
case of options intended to qualify as "performance-based compensation" within
the meaning of Section 162(m) of the Code, consist of two or more "outside
directors" within the meaning of Section 162(m) of the Code.

                                       59
<PAGE>   67

The Administrator has the power to determine the terms of the options or SPRs
granted, including the exercise price, the number of shares subject to each
option or SPR, the exercisability thereof, and the form of consideration payable
upon such exercise. In addition, the Administrator has the authority to amend,
suspend or terminate the 1996 Option Plan, provided that no such action may
affect any share of common stock previously issued and sold or any option
previously granted under the 1996 Option Plan.

     Options and SPRs granted under the 1996 Option Plan are not generally
transferable by the optionee, and each option and SPR is exercisable during the
lifetime of the optionee only by the optionee. Options granted under the 1996
Option Plan must generally be exercised within three months of the end of
optionee's status as an employee or consultant of Extensity, or within twelve
months after an optionee's termination by death or disability, but in no event
later than the expiration of the option's ten year term. In the case of SPRs,
unless the Administrator determines otherwise, the restricted stock purchase
agreement shall grant Extensity a repurchase option exercisable upon the
voluntary or involuntary termination of the purchaser's employment with us for
any reason (including death or disability). The purchase price for shares
repurchased under the restricted stock purchase agreement shall be the original
price paid by the purchaser and may be paid by cancellation of any indebtedness
of the purchaser to us. The repurchase option shall lapse at a rate determined
by the Administrator. The exercise price of all incentive stock options granted
under the 1996 Option Plan must be at least equal to the fair market value of
the common stock on the date of grant. The exercise price of nonstatutory stock
options and SPRs granted under the 1996 Option Plan is determined by the
Administrator, but with respect to nonstatutory stock options intended to
qualify as "performance-based compensation" within the meaning of Section 162(m)
of the Code, the exercise price must at least be equal to the fair market value
of the common stock on the date of grant. With respect to any participant who
owns stock possessing more than 10% of the voting power of all classes of our
outstanding capital stock, the exercise price of any incentive stock option
granted must equal at least 110% of the fair market value on the grant date and
the term of such incentive stock option must not exceed five years. The term of
all other options granted under the 1996 Option Plan may not exceed ten years.

     The 1996 Option Plan provides that in the event of a merger of Extensity
with or into another corporation, a sale of substantially all of our assets,
each option or right shall be assumed or an equivalent option or right
substituted by the successor corporation. If the outstanding options or rights
are not assumed or substituted, the Administrator shall provide for the Optionee
to have the right to exercise the option or SPR as to all of the optioned stock,
including shares as to which it would not otherwise be exercisable for a period
of at least 15 days from the date of such notice, and the option or SPR will
terminate upon the expiration of such period.

  EMPLOYEE STOCK PURCHASE PLAN 2000

     Extensity's Employee Stock Purchase Plan 2000 was adopted by the board of
directors and stockholders of Extensity in November 1999 and will become
effective upon the closing of this offering. A total of 500,000 shares of common
stock have been reserved for issuance under the Purchase Plan. The Purchase Plan
provides for automatic annual increases in the number of shares reserved for
issuance under the plan, in an amount each year equal to the lesser of (1) 1.5%
of the outstanding shares on such date, (2) 500,000 shares or (3) such lesser
amount as may be determined by the board.

     The Purchase Plan, which is intended to qualify under Section 423 of the
Code, contains consecutive, overlapping, twenty-four month offering periods.
Each offering period generally includes four six-month purchase periods. The
offering periods generally start on the first trading day after April 15 and
October 15 of each year, except for the first such offering period.
                                       60
<PAGE>   68

The first offering period commences on the first trading day on or after the
effective date of this offering and ends on the last trading day on or before
April 15, 2002. The first purchase period ends on the last trading day on or
before October 15, 2000.

     Employees are eligible to participate in the Purchase Plan if they are
customarily employed by Extensity or any participating subsidiary for at least
20 hours per week and more than five months in any calendar year. However, any
employee who (1) immediately after grant owns stock possessing 5% or more of the
total combined voting power or value of all classes of our capital stock, or (2)
whose rights to purchase stock under all of our employee stock purchase plans
accrues at a rate which exceeds $25,000 worth of stock for each calendar year
may be not be granted an option to purchase stock under the Purchase Plan. The
Purchase Plan permits participants to purchase common stock through payroll
deductions of up to 15% of the participant's "compensation." Compensation is
defined as the participant's total compensation including base straight time
gross earnings, bonuses and commissions, overtime, shift premium payments,
incentive compensation, incentive payments and other compensation. The maximum
aggregate number of shares that may be issued to employees during the first
purchase period is 1.5% of the then outstanding shares of capital stock;
thereafter, the maximum number of shares that may be issued to employees during
a single purchase period is 1%.

     Amounts deducted and accumulated by the participant are used to purchase
shares of common stock at the end of each purchase period. The price of stock
purchased under the Purchase Plan is generally 85% of the lower of the fair
market value of the common stock (1) at the beginning of the offering period or
(2) at the end of the purchase period. In the event the fair market value at the
end of a purchase period is less than the fair market value at the beginning of
the offering period, the participants will be withdrawn from the current
offering period following exercise and automatically re-enrolled in a new
offering period. The new offering period will use the lower fair market value as
of the first date of the new offering period to determine the purchase price for
future purchase periods. Participants may end their participation at any time
during an offering period, and they will be paid their payroll deductions to
date. Participation ends automatically upon termination of employment with us.

     Rights granted under the Purchase Plan are not transferable by a
participant other than by will, the laws of descent and distribution, or as
otherwise provided under the Purchase Plan. The Purchase Plan provides that, in
the event of a merger of Extensity with or into another corporation or a sale of
substantially all of our assets, each outstanding option may be assumed or
substituted for by the successor corporation. If the successor corporation
refuses to assume or substitute for the outstanding options, the offering period
then in progress will be shortened and a new exercise date will be set. The
Purchase Plan will terminate in 2009. The board of directors has the authority
to amend or terminate the Purchase Plan, except that no such action may
adversely affect any outstanding rights to purchase stock under the Purchase
Plan.

LIMITATION ON LIABILITY AND INDEMNIFICATION MATTERS

     Our certificate of incorporation limits the liability of directors to the
maximum extent permitted by Delaware law. Delaware law provides that directors
of a corporation will not be personally liable for monetary damages for breach
of their fiduciary duties as directors, except for any liability arising with
respect to (1) any breach of their duty of loyalty to the corporation or its
stockholders, (2) acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law or (3) any transaction from
which the director derived an improper personal benefit.

     Our certificate of incorporation further provides that we are authorized to
indemnify our directors and executive officers and may indemnify our other
officers and employees and agents to the fullest extent permitted by Delaware
law. We believe that indemnification under our

                                       61
<PAGE>   69

certificate of incorporation covers negligence and gross negligence on the part
of indemnified parties.

     We have entered into agreements to indemnify our directors and officers, in
addition to indemnification provided for in our certificate of incorporation.
These agreements, among other things, require us to indemnify these directors
and officers for certain expenses (including attorneys' fees), judgments, fines
and settlement amounts incurred by any such person in any action or proceeding,
including any action by or in the right of Extensity, arising out of that
person's services as a director or officer of Extensity, any subsidiary of
Extensity or any other company or enterprise to which the person provides
services at the request of Extensity.

     At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent of Extensity where indemnification would be
required or permitted. We are not aware of any pending or threatened litigation
or proceeding that might result in a claim for such indemnification. We believe
that these provisions and agreements are necessary to attract and retain
qualified directors and officers.

sold shares of our Series B Preferred Stock convertible into an aggregate of

converted to Series C Preferred Stock at the time of our Series D financing and
are convertible into an aggregate of 937,500 shares of common stock. The holders
of our Series B Preferred Stock and Series C Preferred Stock, voting together,
were allotted one seat on our board of directors, currently filled by Ted

Series D Preferred Stock convertible into an aggregate of 3,674,229 shares of
common stock at a price of $3.30 per share, to raise capital to finance our

                          DESCRIPTION OF CAPITAL STOCK

AUTHORIZED AND OUTSTANDING CAPITAL STOCK

     Our authorized capital stock as of December 31, 1999 consisted of
30,000,000 shares of common stock, and 15,082,970 shares of preferred stock. As
of December 31, 1999, there were outstanding 4,205,906 shares of common stock
and 14,594,549 shares of preferred stock. Such shares were held of record by a
total of 228 stockholders.

     Upon the closing of this offering:

     - our certificate of incorporation will be amended and restated to provide
       for total authorized capital consisting of 75,000,000 shares of common
       stock and 5,000,000 shares of preferred stock; and

     - all shares of preferred stock will convert into common stock, and a total
       of 22,800,455 shares of common stock and no shares of preferred stock
       will be outstanding, based on the number of shares outstanding as of
       December 31, 1999 and assuming no exercise of the underwriters'
       over-allotment option, after giving effect to the sale of common stock we
       are offering.

     Common Stock

     The holders of our common stock are entitled to receive dividends as may be
declared by our board of directors and paid out of legally available funds.
Holders of shares of common stock are entitled to one vote per share upon all
matters upon which stockholders have the right to vote. Cumulative voting of
shares is not permitted. In the event of a voluntary or involuntary liquidation,
dissolution or winding up of Extensity, the holders of our common stock are
entitled to receive and share ratably in all assets remaining available for
distribution to stockholders after payment of any preferential amounts to which
the holders of preferred stock may be entitled. Our common stock has no
preemptive rights and is not redeemable, assessable or entitled to the benefits
of any sinking fund. Shares of our common stock held by all other persons are
not convertible. All outstanding shares of our common stock are, and the common
stock to be issued in this offering will be, validly issued, fully paid and
nonassessable.

     Preferred Stock

     As of the closing date of this offering, each outstanding share of
preferred stock will automatically convert into one share of common stock.
Pursuant to an amended and restated certificate of incorporation to be filed
upon the closing date, a total of 5,000,000 shares of preferred stock will be
authorized for issuance, none of which has been designated in any series. Our
board of directors is authorized, without further stockholder action, to
authorize and issue any of the 5,000,000 undesignated shares of preferred stock
in one or more series and to fix the voting rights, liquidation preferences,
dividend rights, repurchase rights, conversion rights, preemption rights,
redemption rights and terms, including sinking fund provisions and certain other
rights and preferences of such shares of our preferred stock. The issuance of
any class or series of preferred stock could adversely affect the rights of the
holders of common stock by restricting dividends on, diluting the power of,
impairing the liquidation rights of common stock, or delaying, deferring or
preventing a change in control of Extensity. We have no present plans to issue
any preferred stock.

WARRANTS

     In connection with certain credit arrangements, we issued to Comdisco
warrants to purchase a total of 160,303 shares of Series D Preferred Stock at an
exercise price, subject to certain adjustments, of $3.30 per share. Following
the closing of the offering, the warrants automatically will become exercisable
for a similar number of shares of common stock at the same exercise price per
share. Comdisco may exercise such warrants by means of (1) a cash payment in an
amount equal to the exercise price or (2) in the event the common stock is
publicly traded, a net issue exercise whereby Comdisco would receive shares
equal to the value of the warrant, as calculated pursuant to the terms set forth
therein. The warrants expire upon the earlier to occur of (A) various dates
ranging from March 25, 2008 to December 25, 2008, (B) 5 years after the
effective date of our initial public offering, or (C) a change in control of
Extensity.

     In connection with certain credit arrangements, we issued to Silicon Valley
Bank a warrant to purchase 23,585 shares of Series B Preferred Stock at an
exercise price, subject to certain adjustments, of $1.59 per share. Following
the closing of this offering, the warrant automatically will become exercisable
for a similar number of shares of Common Stock at the same exercise price per
share. Silicon Valley Bank may exercise the warrant by means of (1) a cash
payment in an amount equal to the exercise price or (2) in the event our common
stock is publicly traded, a net issue exercise whereby Silicon Valley Bank would
receive shares equal to the value of the warrant, as calculated pursuant to the
terms set forth therein. The warrant expires on January 28, 2002.

REGISTRATION RIGHTS

     The holders of approximately 14,594,549 shares of outstanding common stock
held by investors who purchased shares of Series A, Series B, Series C, Series
D, Series E and Series F Preferred Stock, and the holders of warrants to
purchase preferred stock convertible into 183,888 shares of our common stock
will be entitled to certain rights with respect to the registration of such
shares of common stock under the Securities Act. Under the terms of the Amended
and Restated Investor Rights Agreement dated December 16, 1999, if we propose to
register any of our common stock under the Securities Act, the holders of the
registrable securities are entitled to notice of the registration and have the
right to include their registrable securities in the registration. However, the
underwriters have certain rights to limit the number of shares included in any
registration. Beginning 180 days after the closing of the offering, the holders
of at least 40% of the registrable securities (other than Comdisco or Silicon
Valley Bank), have the right to require us on no more than two occasions, to
file a registration statement under the Securities Act in order to register all
or any part of their registrable securities, subject to certain conditions and
limitations. Comdisco and Silicon Valley Bank may include their shares acquired
pursuant to warrant agreements where we have been required to file a
registration statement. We may in certain circumstances defer such
registrations, and the underwriters have the right (subject to certain
limitations) to limit, and in the case of our initial public offering, to
exclude entirely, the number of shares included in such registrations. Further,
the holders of registrable securities may require us to register all or any
portion of their registrable securities on Form S-3, when such form becomes

ANTITAKEOVER EFFECTS OF PROVISIONS OF THE CERTIFICATE OF INCORPORATION, AND
BYLAWS AND OF DELAWARE LAW

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

     Certificate of Incorporation and Bylaws

     Certain provisions of our certificate of incorporation and Bylaws are
designed to enhance the likelihood of continuity and stability of our board of
directors and in the policies formulated thereby. Accordingly, such provisions
may have the effect of preventing, discouraging or delaying any potential
acquisition proposals or changes in the control of our company and of preventing
changes in our management.

     Effect of Delaware Anti-Takeover Statute

     We are subject to Section 203 of the Delaware General Corporation Law
which, subject to certain exceptions, prohibits a Delaware corporation from
engaging in any business combination with any interested stockholder for a
period of three years following the date that the stockholder became an
interested stockholder, unless:

     - the transaction is approved by the board of directors prior to the date
       the interested stockholder attained such status;

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

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

     Generally, a "business combination" includes a merger, asset or stock sale,
or other transaction resulting in a financial benefit to the interested
stockholder. Generally, an "interested stockholder" is a person who, together
with affiliates and associates, owns or within three years prior to the
determination of interested stockholder status, did own, 15% or more of a
corporation's voting stock.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for our common stock is Equiserve.

LISTING

     We have applied to list our common stock on the Nasdaq National Market

</TABLE>

RULE 144

     In general, under Rule 144 a person (or persons whose shares are
aggregated) who has beneficially owned shares for at least one year is entitled
to sell within any three-month period commencing 90 days after the date of this
prospectus a number of shares that does not exceed the greater of

     - 1% of the then outstanding shares of our common stock (approximately
       228,004 shares immediately after this offering) or

     - the average weekly trading volume during the four calendar weeks
       preceding such sale, subject to the filing of a Form 144 with respect to
       the sale.

     A person (or persons whose shares are aggregated) who is not deemed to have
been our affiliate at any time during the 90 days immediately preceding the sale
who has beneficially owned his or her shares for at least two years is entitled
to sell these shares pursuant to Rule 144(k) without regard to the limitations
described above. Affiliates must always sell pursuant to Rule 144, even after
the applicable holding periods have been satisfied.

     We cannot estimate the number of shares that will be sold under Rule 144,
as this will depend on the market price for our common stock, the personal
circumstances of the sellers and other factors. Prior to this offering, there
has been no public market for our common stock, and there can be no assurance
that a significant public market for our common stock will develop or be
sustained after this offering. Any future sale of substantial amounts of our
common stock in the open market may adversely affect the market price of our
common stock.

LOCK-UP AGREEMENTS

     We and our directors, executive officers, substantially all of our
stockholders, and holders of options and warrants to purchase our capital stock
have agreed pursuant to the underwriting

                                       71

public market without restriction under the Securities Act.

RULE 701

     Any of our employees or consultants who purchased his or her shares

underwriters named below, through their representatives Deutsche Bank Securities
Inc., Bear, Stearns & Co. Inc. and Hambrecht & Quist LLC, have severally agreed

stock at a public offering price less the underwriting discounts and commissions
set forth on the cover page of this prospectus:

</TABLE>

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

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

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

     The underwriting fee is equal to the public offering price per share of
common stock less the amount paid by the underwriters to us per share of common
stock. The underwriting fee is currently expected to be approximately 7% of the
initial public offering price. We have agreed to pay the underwriters the
following fees, assuming either no exercise or full exercise by the underwriters
of the underwriters' over-allotment option:

     In addition, we estimate that our share of the total expenses of this
offering, excluding underwriting discounts and commissions, will be
approximately $1,700,000.

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

     Each of our officers and directors, and substantially all of our
stockholders and holders of options and warrants to purchase our stock, have
agreed not to offer, sell, contract to sell or otherwise dispose of, or enter
into any transaction that is designed to, or could be expected to, result in the
disposition of any shares of our common stock or other securities convertible
into or exchangeable or exercisable for shares of our common stock or
derivatives of our common stock owned by these persons prior to this offering or
common stock issuable upon exercise of options or warrants held by these persons
for a period of 180 days after the effective date of the registration statement
of which this prospectus is a part without the prior written consent of Deutsche
Bank Securities Inc. This consent may be given at any time without public
notice. We have entered into a similar agreement with the representatives of the
underwriters, except that we may grant options and sell shares pursuant to our
1996 Stock Option Plan and our Employee Stock Purchase Plan 2000 without such
consent. There are no agreements between the representatives and any of our
stockholders or affiliates releasing them from these lock-up agreements prior to
the expiration of the 180-day period.

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

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

     At our request, the underwriters have reserved for sale, at the initial
public offering price, up to 360,000 shares for our vendors, employees, family
members of employees, customers and other third parties. The number of shares of
our common stock available for sale to the general public will be reduced to the
extent these reserved shares are purchased. Any reserved shares that are not
purchased by these persons will be offered by the underwriters to the general
public on the same basis as the other shares in this offering.


     In July 1999, we sold shares of our Series E Preferred Stock in a private
placement at a price of $6.00 per share. Each of the shares of Series E
Preferred Stock is convertible at the option of the holder into one share of our
common stock. In this private placement, BT Investment Partners, Inc., an
affiliate of Deutsche Bank Securities Inc., purchased 166,666 shares of Series E
Preferred Stock for an aggregate purchase price of $999,996. BT Investment
Partners, Inc. purchased the Series E Preferred Stock on the same terms as the
other investors in the private placement. Upon conversion of these shares into
common stock, based upon an assumed public offering price of $17.00, the value
of these shares is $2,833,322. The difference between the amount that BT
Investment Partners, Inc. originally paid for the Series E preferred stock and
the value of the Series E Preferred Stock based upon the assumed initial


                                       74
<PAGE>   82


public offering price equals $1,833,326. Pursuant to the rules and regulations
of the National Association of Securities Dealers, Inc. these shares of Series E
Preferred Stock, and the common stock issued upon conversion thereof, may not be
sold, transferred, assigned, pledged or hypothecated by any person for a period
of one year after the effective date of this offering, except to officers or
partners of the underwriters and members of the selling group and their officers
or partners.


PRICING OF THIS OFFERING

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

     - prevailing market conditions;

     - our results of operations in recent periods;

     - the present stage of our development;

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

     - estimates of our business potential.

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

                                 LEGAL MATTERS

     The validity of the common stock offered hereby will be passed upon for us
by Wilson Sonsini Goodrich & Rosati, Professional Corporation, Palo Alto,
California. Certain legal matters in connection with this offering will be
passed upon for the underwriters by Morrison & Foerster LLP, Irvine, California.
At the close of this offering, WS Investments, an investment partnership
composed of some current and former members of and persons associated with
Wilson Sonsini Goodrich & Rosati, a Professional Corporation, as well as an
individual attorney at this firm, will beneficially own a total of 47,603 shares
of our common stock.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders of
Extensity, Inc.

     In our opinion, the accompanying consolidated balance sheets and the
related consolidated statements of operations, of stockholders' deficit and of
cash flows present fairly, in all material respects, the financial position of
Extensity, Inc. as of December 31, 1998 and 1999, and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1999, in conformity with generally accepted accounting principles.
These financial statements are the responsibility of the Company's management;
our responsibility is to express an opinion on these financial statements based
on our audits. We conducted our audits in accordance with generally accepted
auditing standards which 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, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. ORGANIZATION AND BASIS OF PRESENTATION

     Extensity, Inc. (the Company) provides Internet-based workforce
optimization software applications designed to improve the productivity of
employees across the enterprise and to enhance enterprise operating efficiency.
The Company was incorporated as Celerity, Inc. in Delaware in November 1995,
changed its name from Celerity, Inc. to At Large Software, Inc. effective April
12, 1996, and changed its name from At Large Software, Inc. to Extensity, Inc.,
effective August 19, 1997.

     In October 1999, the Company's Board of Directors authorized the Company to
file a registration statement with the Securities and Exchange Commission for
the purpose of an initial public offering of the Company's common stock. Upon
the completion of this offering, the Company's preferred stock will be converted
into shares of common stock, and all outstanding shares of preferred stock will
be cancelled and retired. The pro forma effect of the conversion has been
presented as a separate column in the Company's balance sheet, assuming the
conversion had occurred as of December 31, 1999.

     The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiary, Extensity Europe Limited, which commenced
operations in September 1999. All significant intercompany balances and
transactions have been eliminated in consolidation.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the 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.

CASH AND CASH EQUIVALENTS

     The Company considers all investments with an original maturity of three
months or less to be cash equivalents. The Company periodically maintains cash
balances at banks in excess of the Federal Deposit Insurance Corporation
insurance limit of $100,000.

SHORT TERM INVESTMENTS

     The Company accounts for its investments in quality corporate debt
securities under the provisions of Statement of Financial Accounting Standards
No. 115 (SFAS 115), Accounting for Certain Investments in Debt and Equity
Securities. The Company has classified all marketable debt securities as
held-to-maturity and has accounted for these investments at amortized cost. As
of December 31, 1999, the Company's carrying value of its short term investments
approximated their amortized cost basis.

RESTRICTED SHORT TERM INVESTMENT

     The restricted short term investment consists of several one year
certificates of deposit required as collateral for the Company's letters of
credit (Note 5).

                                EXTENSITY, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

CONCENTRATION OF CREDIT RISK AND CERTAIN RISKS

     Financial instruments that potentially subject the Company to a
concentration of credit risk consist of cash and cash equivalents, short term
investments and accounts receivable. The Company's accounts receivable are
derived from revenue earned from customers located primarily in the United
States. The Company performs credit evaluations of its customers' financial
condition and, generally, requires no collateral from its customers. The Company
maintains an allowance for doubtful accounts receivable based upon the expected
collectibility of accounts receivable.

     At December 31, 1998, two customers accounted for 60% of total accounts
receivable. At December 31, 1999, one customer accounted for 10% of total
accounts receivable.

     Four customers accounted for 66% of total revenue during fiscal 1998. One
customer accounted for 11% of total revenues during fiscal 1999.

     All of the Company's revenues were derived from U.S. customers.

     The market in which the Company competes is characterized by changing
customer needs, frequent new software product introductions and rapidly evolving
industry standards. Significant technological change could adversely affect the
Company's operating results.

     The Company operates in one single reportable business segment and,
therefore, no disclosures under SFAS 131, Disclosures about Segments of an
Enterprise and Related Information, are necessary.

SOFTWARE DEVELOPMENT COSTS

     The Company capitalizes internally generated software development costs
under the provision of Statement of Financial Accounting Standards No. 86 (SFAS
86), Accounting for Costs of Computer Software to be Sold, Leased or Otherwise
Marketed. Capitalization of computer software development costs begins upon the
establishment of technological feasibility, which the Company has defined as
completion of a working model. Internally generated capitalizable software
development costs have not been material for years ended December 31, 1999, 1998
and 1997. The Company has not capitalized any software development costs to
date, and has charged software development costs as incurred to research and
development expense in the accompanying consolidated statements of operations.

ADVERTISING COSTS

     Amounts received under co-marketing agreements with strategic partners are
recorded as a reduction of advertising expenses incurred in connection with such
agreements. Immaterial amounts have been received during the three-year period
ended December 31, 1999.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost. Depreciation and amortization
are calculated using the straight-line method over estimated useful lives of
three years, or over the lease term if it is shorter for leasehold improvements.

                                       F-8
<PAGE>   92
                                EXTENSITY, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     When assets are sold or retired, the cost and related accumulated
depreciation and amortization are removed from the accounts and any resulting
gain or loss is included in operations. Maintenance and repairs are charged to
operations as incurred.

INCOME TAXES

     Income taxes are accounted for in accordance with Statement of Financial
Accounting Standards No. 109, Accounting for Income Taxes(SFAS No. 109). Under
SFAS No. 109, deferred income tax liabilities and assets are determined based on
the difference between the financial reporting amounts and tax bases of assets
and liabilities that will result in taxable or deductible amounts in the future
based on enacted tax laws and rates in effect for the years in which the
differences are expected to affect taxable income. Valuation allowances are
established when necessary to reduce deferred tax assets to the amounts expected
to be realized. Income tax expense is the tax payable for the period and the
change during the period in deferred tax assets and liabilities.

REVENUE RECOGNITION

     In October 1997, the American Institute of Certified Public Accountants
issued Statement of Position 97-2, Software Revenue Recognition (SOP 97-2).The
Company adopted SOP 97-2 beginning in fiscal 1998. SOP 97-2 has been modified by
SOP 98-4 and SOP 98-9 as it relates to certain transactions. These standards
generally require revenues earned on software arrangements involving multiple
elements such as software products, upgrades, enhancements, postcontract
customer support, installation and training to be allocated to each element
based on the relative fair values of the elements. The fair value of an element
must be based on evidence that is specific to the vendor. Evidence of the fair
value of each element is based on the price charged when the element is sold
separately or, if the element is not being sold separately, the price for each
element established by management having relevant authority; substantive renewal
terms for maintenance services included in contracts also serves as evidence of
fair value for such services.

     The Company's software products require installation services that
primarily consist of configuring the software to incorporate a customer's
business policies, workflow approvals and interfaces to information systems used
by its customers. Prior to the release in July 1999 of Version 4.0, it was
difficult to develop dependable estimates of the costs necessary to complete
product implementations. Therefore, the Company accounted for its software
licenses and implementation revenues using the completed contract method of
contract accounting as required under the provisions of SOP 97-2 and SOP 81-1,
Accounting for Performance of Construction-Type and Certain Production-Type
Contracts. Following the release of Version 4.0 in July 1999, the Company was
able to develop dependable estimates of the costs necessary to complete
implementation of the substantially enhanced Version 4.0 product. Consequently,
the Company is accounting for its Version 4.0 software licenses and
implementation revenues using the percentage-of-completion method of contract
accounting. The percentage-of-completion method is applied based upon man-days
incurred as a percentage of total estimated man-days. In cases where a sale of a
license does not include implementation services (i.e., a sale of additional
seats), such revenue is recorded upon delivery with an appropriate deferral for
maintenance services, if applicable.

     Amounts billed for maintenance are deferred and recognized ratably over the
maintenance period.

                                       F-9
<PAGE>   93
                                EXTENSITY, INC.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     The Company has entered into two agreements under which certain
distributors would receive unspecified future products over the life of the
arrangements (two or three years) in consideration for agreed-upon
non-refundable fees. Consistent with SOP 97-2, the Company recognizes such fees
ratably, on a subscription basis, over the term of the related agreements.

     Revenue for contracts containing specified upgrades for which no vendor
specific objective evidence (VSOE) of fair value exists is deferred until such
specified upgrades are delivered or VSOE is established.

STOCK-BASED COMPENSATION

     The Company accounts for stock-based employee compensation arrangements in
accordance with the provisions of Accounting Principles Board Opinion No. 25,
Accounting for Stock Issued to Employees (APB No. 25) and complies with the
disclosure provisions of Statement of Financial Accounting Standards No. 123,
Accounting for Stock-Based Compensation(SFAS No. 123). Under APB No. 25,
compensation expense is based on the difference, if any, between the fair value
of the Company's stock and the exercise price of the option on the measurement
date, which is typically the date of grant (see Note 9).

     The Company accounts for options granted to non-employees under SFAS No.
123. Under SFAS No. 123, options are recorded at their fair value on the
measurement date, which is typically the date of grant.

HISTORICAL AND PRO FORMA NET LOSS PER SHARE

     Historical basic and diluted net loss per share are computed using the
weighted average number of common shares outstanding. Options, warrants and
preferred stock were not included in the computation of diluted net loss per
share because the effect would be antidilutive.

     Pro forma net loss per share has been computed assuming the conversion of
all outstanding shares of convertible preferred stock into shares of common
stock.

     Due to the uncertainty of realization, a valuation allowance has been
provided to offset net deferred tax assets at December 31, 1998 and 1999. The
increase in the valuation allowance was $4,040,000 and $8,005,000 during the
years ended December 31, 1998 and 1999, respectively.

     As of December 31, 1999, the Company had net operating loss carryforwards
of approximately $33.0 million and 18.0 million for federal and state income tax
purposes, respectively. Such carryforwards expire through 2019 and 2004 for
federal and state income tax purposes, respectively. At December 31, 1999, the
Company also had research and experimentation tax credit carryforwards of
$720,000 and $450,000 for federal and state purposes, respectively, which expire
in varying amounts through 2014.

     Under the Tax Reform Act of 1986, the benefits from net operating loss and
tax credit carryforwards may be impaired or limited in certain circumstances
including as a result of a cumulative ownership change of more than 50%, as
defined, over a three-year period. The issuance of the Company's convertible
preferred securities may have resulted in a limitation on utilization of such
net operating loss carryforwards.

5. COMMITMENTS

     During 1998, the Company entered into various lease agreements for computer
and office equipment. The Company leases office space under a noncancelable
operating lease expiring in June 2003. Total rent expense for 1998 and 1997
aggregated $383,000 and $88,000,

     In connection with certain capital lease transactions, the Company granted
to the lessor warrants to purchase 22,425 shares of Series D preferred stock at
an exercise price of $3.30 per share. Such warrants were valued at approximately
$44,000 using the Black-Scholes valuation model with the following assumptions:
expected volatility of 40%, risk-free interest rate of 6% and expected life of
10 years. The value of these warrants was recorded as a long-term asset, which
is being amortized over the capital lease term of 4 years. Such amortization
amounted to $5,000 and $19,000 during the years ended December 31, 1998 and
1999, respectively.

     The Company has established a $45,000 letter of credit with a bank for the
benefit of the Company's office space lessor. The letter of credit accrues
interest at the bank's prime rate and is collateralized by a $33,000 certificate
of deposit. As of December 31, 1999, no amounts were outstanding under the
letter of credit.

6. DEBT

     In March 1998, the Company entered into a loan and security agreement with
a lender for $3,500,000. Borrowings under this loan accrue interest at an
average rate of 11.4% per annum and mature through March 25, 2001. The agreement
provides the lender with the right to exercise warrants to purchase 137,878
shares of Series D preferred stock at an exercise price of $3.30 per share. The
Company recorded the loan at a discount of approximately $265,000, which was
allocated to the warrants. The debt discount was calculated in accordance with
the provisions of APB No. 14, Accounting for Convertible Debt and Debt Issued
with Stock Purchase Warrant. The fair value of the warrants was estimated on the
date of grant using the Black-Scholes model with expected volatility of 40%,
risk-free interest of 6% and expected life of 10 years. Amortization of the debt
discount was recorded as interest expense and amounted to $58,000 and $88,000
during the year ended December 31, 1998 and December 31, 1999, respectively.

     During 1999, the Company's Board of Directors approved an amendment to the
Company's Certificate of Incorporation to increase the number of its authorized
shares of common stock and preferred stock to 30,000,000 and 15,082,970,
respectively.

     On December 16, 1999, the Company sold 500,000 shares of its Series F
Preferred Stock at a price of $9.00 per share for gross proceeds of $4.5 million
in cash to an investor. The Company also entered into a commercial relationship
with this investor. The difference between the deemed fair value of the series F
preferred stock of $12.00 and the price per share of $9.00 was deemed to be a
beneficial conversion feature analogous to a dividend to the preferred
stockholders as prescribed under the provisions of EITF 98-5, Accounting for
Convertible Securities with Beneficial Conversion Features or Contingently
Adjustable Conversion Ratios. The value of the beneficial conversion feature of
$1.5 million was recognized immediately at the date of issuance as the preferred
stockholders have the right to convert their preferred shares at their option.

     Each share of Series A, B, C, D, E and F preferred stock is convertible
into common stock at the option of the stockholder on a one-for-one basis,
subject to certain adjustments. Each share of Series A, B, C, D, E and F
preferred stock will automatically convert to common stock upon the earlier of
the closing date of an underwritten public offering of the Company's common
stock with an offering price of not less than $8.00 per share and aggregate
proceeds in excess of $15,000,000 or the date of mutual consent of the holders
of 60% of the then outstanding preferred stock voting as a class.

     Holders of preferred stock are entitled to one vote for each share of
common stock into which such shares may be converted. Each share of Series A, B,
C, D, E and F preferred stock entitles the stockholder to receive annual
noncumulative dividends of $0.045, $0.144, $0.18, $0.30, $0.54 and $0.81
respectively, in preference to holders of shares of common stock, if and when
declared by the Board of Directors. No dividends have been declared to date.

     In the event of any liquidation, dissolution or winding up of the Company,
holders of Series A, B, C, D, E and F preferred stock are entitled to receive
$0.50, $1.60, $2.00, $3.30, $6.00 and $9.00 per share, respectively, and all
declared but unpaid dividends prior and in preference to any distribution to
holders of common stock. After payment has been made to the holders of preferred
stock, any remaining assets will be distributed ratably among the holders of
preferred and common stock in proportion to the number of shares of common stock
held by each, assuming conversion of all Series A, B, C, D, E and F preferred
stock until certain limits are reached. If the Company's assets are insufficient
to provide for the full preference amount for the preferred stock outstanding,
then such assets will be distributed ratably among the holders of the preferred
stock in proportion to the amount of such stock owned by each stockholder.

     At any time after May 31, 2004, the holders of at least 75% of the then
outstanding shares of Series A, B, C, D, E and F preferred stock may require the
Company to redeem all or any part of the then outstanding shares of Series A, B,
C, D, E and F preferred stock at a price equal to $0.50, $1.60, $2.00, $3.30,
$6.00 and $9.00 per share, respectively, plus all declared but unpaid dividends
on such shares.

PREFERRED STOCK WARRANTS ISSUED IN CONNECTION WITH FINANCINGS

     On January 29, 1997, the Company entered into a loan and security agreement
with a bank. During fiscal 1997, $250,000 was drawn on the loan and was repaid
in the same year. This loan expired on June 15, 1997. In conjunction with this
loan agreement, the Company issued to the lender a warrant to purchase 23,585
shares of Series B preferred stock at an exercise price per share of $1.59. The
Company recorded the loan at a discount of $24,000 which discount was allocated
to the warrant and amortized as interest expense during 1997. The fair value of
the warrant was estimated on the date of grant using the Black-Scholes model
with expected volatility of 60%, risk-free interest of 5.50% and expected life
of 5 years. The warrant expires on January 28, 2002 and was not exercised as of
December 31, 1999.

     During 1998, the Company entered into financing agreements with a financial
institution (see Note 6). In conjunction with these transactions, the Company
issued to the financial institution warrants to purchase shares of Series D
preferred stock at an exercise price of $3.30 per share. These warrants expire
through December 2008 and none were exercised as of December 31, 1999.

8. COMMON STOCK

     During 1998, the Company issued a total of 47,703 shares of its common
stock at fair value to several service providers. The Company recorded the fair
values of the common stock which amounted to $7,300 as compensation expense.

     During the year ended December 31, 1999, the Company loaned to three
officers an aggregate of $230,000 to exercise options to purchase 933,439 shares
of the Company's common stock. The officers paid $193,750 in cash in conjunction
with this exercise. The promissory note to one of the officers bears interest at
4.77%, is due on February 28, 2004 and is collateralized by the common stock
purchased for cash. The cash portion of the exercise of $150,000 exceeded the
face value of the note by $50,000. The officer repaid the note in full,
including $3,000 in interest, in November 1999. The notes of the other two
officers bear interest at 5.87%, are due on July 16, 2004 and are collateralized
by their personal assets.

9. STOCK OPTIONS

     In 1996, the Company adopted the 1996 Stock Option Plan (the Plan) under
which eligible employees, directors, and consultants can receive options to
purchase shares of the Company's common stock at a price generally not less than
100% of the fair value of the common stock on the date of the grant for
incentive stock options and nonstatutory stock options. The Plan, as amended
through December 31, 1999, allows for the issuance of a maximum of 6,100,000
shares of the Company's common stock. This number of shares of common stock has
been reserved for issuance under the Plan. The options granted under the Plan
vest according to varying schedules determined by the Plan Administrator,
currently the Board of Directors. Options generally vest over four years and
expire ten years from the date of grant.

     A summary of the activity under the Plan since inception is set forth

</TABLE>

     The Plan allows certain option holders to exercise their options prior to
vesting. However, such exercises are subject to repurchase by the Company if not
vested. The Company's repurchase right lapses over a four year period. As of
December 31, 1999, 1,310,527 shares of common stock acquired by option holders
are subject to repurchase by the Company.

     The Company accounts for employee and board of director stock options in
accordance with the provisions of APB No. 25 and complies with the disclosure
provisions of SFAS No. 123.

     Under APB No. 25, compensation expense is recognized based on the amount by
which the fair value of the underlying common stock exceeds the exercise price
of the stock options at the measurement date, which in the case of employee
stock options is typically the date of grant. For financial reporting purposes,
the Company has determined that the deemed fair market value on the date of
grant of certain employee stock options was in excess of the exercise price of
the options. This amount is recorded as deferred compensation and is classified
as a reduction of stockholders' equity and is amortized as a charge to
operations over the vesting period of the applicable options. The vesting period
is generally four years. The fair value per share used to calculate deferred
compensation was derived by reference to the preferred stock values and the
Company's initial public offering price range. Consequently, the Company
recorded deferred stock compensation of $0 and $10,205,000 during the year ended
December 31, 1998 and 1999, respectively. Amortization recognized for the year
ended December 31, 1998 and 1999 totaled $0 and $4,352,000, respectively.

     The weighted average fair values of the options granted in fiscal 1997,
1998, and 1999 were $0.06, $0.81, and $2.98, respectively.

     Had compensation cost for option grants to employees been determined
consistent with SFAS No. 123, the Company's net loss would have been as follows
(in thousands, except per share data):

     The above pro forma disclosures are not necessarily representative of the
effects on reported income or loss for future years as additional grants are
made each year and options vest over several years.

     The fair value of each option grant was estimated on the date of grant
using the minimum value options pricing model with the following weighted
average assumptions by period:

     Because the Company does not have actively traded equity securities,
volatility is not considered in determining the value of options granted to
employees.

     In October 1999, the Board of Directors authorized, subject to
stockholders' approval, (i) establishment of the Employee Stock Purchase Plan
2000 (ESPP) with 500,000 shares reserved for issuance and (ii) the amendment of
the Company's 1996 Stock Option Plan to provide for, among other things, an
increase to 7,000,000 of the number of shares of common stock reserved for
issuance thereunder, and an annual replenishment of the shares of common stock
authorized for issuance thereunder equal to the lesser of (a) 1,300,000 shares,
(b) 4% of the outstanding shares on such date or (c) a lesser amount to be
determined by the Board. The ESPP and the amendment to the Company's 1996 Stock
Option Plan will become effective upon the closing of the initial public
offering.


     Subsequent to December 31, 1999, the Company granted options to purchase
461,104 and 157,350 shares of the Company's common stock at exercise prices of
$9.00 and $12.00, respectively. Such grants will result in an additional $1.9
million deferred compensation charge to be recorded in the first quarter of
fiscal 2000.


10. 401(k) PLAN

     In January 1998, the Company adopted a 401(k) plan for employees. All
employees who meet certain service requirements are eligible to participate.
Matching contributions are at the discretion of the Company. The Company made no
matching or discretionary contributions during 1998 and 1999.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS

     As permitted by Section 145 of the Delaware General Corporation Law, the
Registrant's certificate of incorporation includes a provision that eliminates
the personal liability of its directors for monetary damages for breach or
alleged breach of their duty of care to the Company or its stockholders. In
addition, as permitted by Section 145 of the Delaware General Corporation Law,
the certificate of incorporation of the Registrant provides, inter alia, that
each person who is made a party or is threatened to be made a party to or
otherwise involved in any action, suit or proceeding, whether civil, criminal,
administrative or investigative (hereinafter a "proceeding"), by reason of the
fact that he or she is or was a director or officer of the Company or, while a
director or officer of the Company, is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation or of a
partnership, joint venture, trust or other enterprise, including service with
respect to an employee benefit plan (hereinafter an "indemnitee"), whether the
basis of such proceeding is alleged action in an official capacity as a director
or officer or in any other capacity while serving as a director or officer, is
authorized to be indemnified and held harmless by the Company to the fullest
extent authorized by the Delaware General Corporation Law, as the same exists or
may hereafter be amended, against all expense, liability and loss (including
attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts
paid in settlement) reasonably incurred or suffered by such indemnitee in
connection therewith and such indemnification shall continue as to an
indemnitee's heirs, executors and administrators; provided, however, that,
except with respect to the proceedings brought by an indemnitee to enforce
rights to indemnification (subject to certain restrictions and as more fully
described in the Registrant's certificate of incorporation), the Company shall
indemnify any such indemnitee in connection with a proceeding (or part thereof)
initiated by such indemnitee only if such proceeding (or part thereof) was
authorized by the Board of Directors of the Company. The right to
indemnification conferred in the Registrant's certificate of incorporation
includes the right to be paid by the Company the expenses incurred in connection
with any such proceeding in advance of its final

                                      II-1
<PAGE>   104

disposition; provided, however, that, if and to the extent that the Delaware
General Corporation Law requires, such an advancement of expenses incurred by an
indemnitee in his or her capacity in which service was or is rendered by such
indemnitee, including, without limitation, service with respect to an employee
benefit plan, shall be made only upon delivery to the Company of an undertaking
by or on behalf of such indemnitee, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal that such indemnitee is not entitled to be indemnified
for such expenses under the Company's certificate of incorporation or otherwise.

     The Registrant's policy is to enter into indemnification agreements with
each of its directors and executive officers that provide the maximum indemnity
allowed to directors and executive officers by Section 145 of the Delaware
General Corporation Law and the Bylaws, as well as certain additional procedural
protections. The indemnity agreements provide that directors and executive
officers will be indemnified to the fullest possible extent not prohibited by
law against all expenses (including attorney's fees) and settlement amounts paid
or incurred by them in any action or proceeding, including any derivative action
by or in the right of the Registrant, on account of their services as directors
or executive officers of the Registrant or as directors or officers of any other
company or enterprise when they are serving in such capacities at the request of
the Registrant. Pursuant to the indemnity agreements, the Company will not be
obligated to indemnify or advance expenses to an indemnified party with respect
to proceedings or claims initiated by the indemnified party and not by way of
defense, except with respect to proceedings specifically authorized by the Board
of Directors or brought to enforce a right to indemnification under such
indemnity agreement, the Company's certificate of incorporation, Bylaws or any
statute or law, or as otherwise required under Section 145 of the Delaware
General Corporation Law. Also under the indemnity agreements, the Company is not
obligated to indemnify the indemnified party for (i) any expenses incurred by
the indemnified party with respect to any proceeding instituted by the
indemnified party to enforce or interpret the agreement, if a court of competent
jurisdiction determines that each of the material assertions made by the
indemnified party in such proceeding was not made in good faith or was
frivolous, (ii) acts, omissions or transactions on the part of the indemnified
party from which such party may not be relieved of liability under applicable
law or (iii) expenses and the payment of profits arising from the purchase and
sale by the indemnified party of securities in violation of Section 16(b) of the
Exchange Act, or any similar or successor statute.

     The indemnification provisions in the certificate of incorporation and the
indemnification agreements entered into between the Registrant and its directors
and executive officers, may be sufficiently broad to permit indemnification of
the Registrant's officers and directors for liabilities arising under the 1933
Act.

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

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES

     The following sets forth information regarding all securities sold by us
since January 1997:

      1. In January 1997, we issued and sold a warrant to purchase 23,585 shares
         of Series B Preferred Stock at an exercise price of $1.59 per share to
         Silicon Valley Bank. The foregoing purchase and sale was exempt from
         registration under the Securities Act pursuant to Section 4(2) thereof
         on the basis that the transaction did not involve a public offering.

      2. In May 1997, we issued and sold an aggregate of 3,750,000 shares of
         Series B Preferred Stock to a total of nine investors for $1.59 per
         share, or an aggregate of $5,962,500. In May 1997 we also issued and
         sold warrants to purchase up to 937,500 shares of Series C Preferred
         Stock at an exercise price of $2.00 per share to the same nine
         investors, all of whom exercised their warrants in June 1998. We
         believe that because the offering was made to sophisticated persons
         without the means of a general solicitation, the offering was exempt
         from registration under Section 4(2) of the Securities Act, and
         Regulation D promulgated thereunder.

      3. From August 1997 through December 1997 we issued and sold an aggregate
         of 27,758 shares of common stock at a purchase price of $0.16 per share
         to five consultants. The foregoing purchases and sales were exempt from
         registration under the Securities Act pursuant to Section 4(2) thereof
         on the basis that the transaction did not involve a public offering.

      4. In March 1998, we issued and sold an aggregate of 2,500 shares of
         common stock at a purchase price of $0.16 per share to a consultant.
         The foregoing purchases and sales were exempt from registration under
         the Securities Act pursuant to Section 4(2) thereof on the basis that
         the transaction did not involve a public offering.

      5. On June 2, 1998, we issued and sold an aggregate of 1,445 shares of
         common stock at a purchase price of $0.16 per share to a consultant.
         The foregoing purchase and sale was exempt from registration under the
         Securities Act pursuant to Section 4(2) thereof on the basis that the
         transaction did not involve a public offering.

      6. On June 26, 1998, September 15, 1998 and September 30, 1998, we issued
         and sold an aggregate of 3,674,229 shares of Series D Preferred Stock
         to a total of 14 investors for $3.30 per share, or an aggregate of
         $12,124,957.

      7. In June 1998 and December 1998, we issued and sold warrants to purchase
         160,303 shares of Series D Preferred Stock to Comdisco, Inc. at an
         exercise price of $3.30 per share for an aggregate purchase price of
         $529,003. The foregoing purchases and sales were exempt from
         registration under the Securities Act pursuant to Section 4(2) thereof
         on the basis that the transaction did not involve a public offering.

      8. On July 6, 1998, we issued and sold an aggregate of 10,000 shares of
         common stock at a purchase price of $0.33 per share to two consultants.
         The foregoing purchases and sales were exempt from registration under
         the Securities Act pursuant to Section 4(2) thereof on the basis that
         the transaction did not involve a public offering.

      9. In June 1999, we issued and sold an aggregate of 6,000 shares of common
         stock at a purchase price of $0.70 per share to three investors for an
         aggregate purchase price of $4,200. The foregoing purchases and sales
         were exempt from registration under the Securities Act pursuant to
         Section 4(2) thereof on the basis that the transaction did not involve
         a public offering.

                                      II-3
<PAGE>   106

     10. On July 27, 1999 and August 20, 1999, we issued and sold an aggregate
         of 3,732,820 shares of Series E Preferred Stock to a total of 47
         investors for $6.00 per share, or an aggregate of $22,396,920. We
         believe that the offering was exempt from registration under Section
         4(2) of the Securities Act, and Regulation D promulgated thereunder.

     11. On December 16, 1999, we issued and sold an aggregate of 500,000 shares
         of Series F Preferred Stock to one investor for $9.00 per share, or an
         aggregate of $4,500,000. We believe that because the offering was made
         without the means of a general solicitation, the offering was exempt
         from registration under Section 4(2) of the Securities Act, and
         Regulation D promulgated thereunder.

     12. Since January 1997, we have granted stock options under our 1996 Stock
         Option Plan, covering an aggregate of 4,876,389 shares of common stock
         (net of expirations and cancellations) at exercise prices ranging from
         $0.10 to $6.00.

     13. Since January 1997, options to purchase an aggregate of 2,050,265
         shares of common stock under our 1996 Stock Option Plan were exercised
         with a weighted average exercise price of approximately $0.62 per
         share.

     None of the foregoing transactions involved any underwriters, underwriting
discounts or commissions, or any public offering, and we believe that each
transaction was exempt from the registration requirements of the Securities Act
by virtue of Section 4(2) thereof, Regulation D promulgated thereunder or Rule
701 pursuant to compensatory benefit plans and contracts relating to
compensation as provided under such Rule 701. The recipients in such
transactions represented their intention to acquire the securities for
investment only and not with a view to or for sale in connection with any
distribution thereof, and appropriate legends were affixed to the share
certificates and instruments issued in such transactions. All recipients had
adequate access to information about the Company.

     In particular, the securities described in the Preferred Stock financings
and warrant issuances pursuant to numbers 1, 2 (except for the warrant issued to
Silicon Valley Bank), 6, 7, 10 and 11 are owned in their entirety by individuals
or large institutional investors who (A) represented to us that they were
"accredited investors" within the definition of Rule 501 of Regulation D,
familiar with investing in private companies, (B) represented to us that they
understood that the securities they were purchasing were restricted and the risk
of possible loss associated with their investment, (C) represented to us that
they were familiar with our history and business, (D) received our recent
financial information and (E) were afforded the opportunity to ask questions of
our management. Each of the investors had expressed previous interest to our
officers and directors in making an investment in us when an opportunity was
available, and such investors were contacted only on a one-on-one basis without
any general solicitation or advertising of the investment opportunity.
Accordingly, we believe that the each of the foregoing

                                      II-4
<PAGE>   107

transactions was exempt from the registration requirements of the Securities Act
by virtue of Section 4(2) thereof.

ITEM 17. UNDERTAKINGS

     The undersigned hereby undertakes to provide to the underwriters at the
closing specified in the underwriting agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

     Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions referenced in Item 14 of this Registration
Statement or otherwise, the Registrant has been advised that in the opinion of
the Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act, and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer,
or controlling person of the Registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered hereunder, the Registrant
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as
expressed in the 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 Act, the
     information omitted from the form of Prospectus filed as part of this
     Registration Statement in reliance upon Rule 430A and contained in a form
     of Prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
     497(h) under the 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 Act, each
     post-effective amendment that contains a form of Prospectus shall be deemed
     to be a new Registration Statement relating to the securities offered
     therein, and the offering of such securities at that time shall be deemed
     to be the initial bona fide offering thereof.

Deutsche Bank Securities Inc.
Bear, Stearns & Co. Inc.
Hambrecht & Quist LLC
As Representatives of the
     Several Underwriters
c/o Deutsche Bank Securities Inc.
One South Street
Baltimore, Maryland 21202

Ladies and Gentlemen:

      Extensity, Inc., a Delaware corporation (the "Company"), proposes to sell
to the several underwriters (the "Underwriters") named in Schedule I hereto for
whom you are acting as representatives (the "Representatives") an aggregate of
4,000,000 shares of the Company's Common Stock, $.001 par value (the "Firm
Shares"). The respective amounts of the Firm Shares to be so purchased by the
several Underwriters are set forth opposite their names in Schedule I hereto.
The Company also proposes to sell at the Underwriters' option an aggregate of up
to 600,000 additional shares of the Company's Common Stock (the "Option Shares")
as set forth below.

      As the Representatives, you have advised the Company (a) that you are
authorized to enter into this Agreement on behalf of the several Underwriters,
and (b) that the several Underwriters are willing, acting severally and not
jointly, to purchase the numbers of Firm Shares set forth opposite their
respective names in Schedule I, plus their pro rata portion of the Option Shares
if you elect to exercise the over-allotment option in whole or in part for the
accounts of the several Underwriters. The Firm Shares and the Option Shares (to
the extent the aforementioned option is exercised) are herein collectively
called the "Shares."



                                       1
<PAGE>   2

      Deutsche Bank Securities Inc. ("Deutsche Bank") has agreed to reserve a
portion of the Shares to be purchased by it under this Agreement for sale to the
Company's directors, officers, employees and business associates and other
parties related to the Company (collectively, "Participants"), as set forth in
the Prospectus under the heading "Underwriters" (the "Directed Share Program").
The Shares to be sold by Deutsche Bank pursuant to the Directed Share Program
are hereinafter referred to as the "Directed Shares." Any Directed Shares not
orally confirmed for purchase by any Participants by the end of the business day
on which this Agreement is executed will be offered to the public by the
Underwriters as set forth in the Prospectus.

      In consideration of the mutual agreements contained herein and of the
interests of the parties in the transactions contemplated hereby, the parties
hereto agree as follows:

      1.    REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

            The Company represents and warrants to each of the Underwriters as
follows:

            (a)   A registration statement on Form S-1 (File No. 333-90979) with
respect to the Shares has been prepared by the Company in conformity with the
requirements of the Securities Act of 1933, as amended (the "Act"), and the
Rules and Regulations (the "Rules and Regulations") of the Securities and
Exchange Commission (the "Commission") thereunder and has been filed with the
Commission. Copies of such registration statement, including any amendments
thereto, the preliminary prospectuses (meeting the requirements of the Rules and
Regulations) contained therein and the exhibits, financial statements and
schedules, as finally amended and revised, have heretofore been delivered by the
Company to you. Such registration statement, together with any registration
statement filed by the Company pursuant to Rule 462(b) of the Act, herein
referred to as the "Registration Statement," which shall be deemed to include
all information omitted therefrom in reliance upon Rule 430A and contained in
the Prospectus referred to below, has become effective under the Act and no
post-effective amendment to the Registration Statement has been filed as of the
date of this Agreement. "Prospectus" means the form of prospectus first filed
with the Commission pursuant to Rule 424(b). Each preliminary prospectus
included in the Registration Statement prior to the time it becomes effective is
herein referred to as a "Preliminary Prospectus." Any reference herein to any
Prospectus shall be deemed to include any supplements or amendments thereto,
filed with the Commission after the date of the filing of the Prospectus under
Rules 424(b) or 430A, and prior to the termination of the offering of the Shares
by the Underwriters.

            (b)   The Company has been duly organized and is validly existing as
a corporation in good standing under the laws of the State of Delaware, with
corporate power and authority to own or lease its properties and conduct its
business as described in the Registration Statement. Extensity Europe Limited
(the "Subsidiary") has been duly organized and is validly existing as a
corporation in good standing under the laws of the jurisdiction of its
incorporation, with corporate power and authority to own or lease its properties
and conduct its business as described in the Registration Statement. The
Subsidiary is the only subsidiary, direct or indirect,



                                       2
<PAGE>   3

of the Company. Each of the Company and the Subsidiary are duly qualified to
transact business in all jurisdictions in which the conduct of their business
requires such qualification and the failure to be so qualified would have a
material adverse effect on the Company. The outstanding shares of capital stock
of the Subsidiary have been duly authorized and validly issued, are fully paid
and non-assessable and are owned by the Company free and clear of all liens,
encumbrances and equities and claims; and no options, warrants or other rights
to purchase, agreements or other obligations to issue or other rights to convert
any obligations into shares of capital stock or ownership interests in the
Subsidiary are outstanding.

            (c)   The outstanding shares of the Company's Common Stock and
Preferred Stock have been duly authorized and validly issued and are fully paid
and non-assessable; the shares of Common Stock to be issued upon conversion of
the Preferred Stock immediately prior to the closing of the offering of the
Shares have been duly authorized and when issued will be validly issued, fully
paid and non-assessable; the Shares have been duly authorized and when issued
will be validly issued, fully paid and non-assessable; and no preemptive or
similar rights granted by the Company to any person pursuant to the charter
documents of the Company or any contract or agreement with the Company exist
with respect to any of the Shares or the issue and sale thereof. Neither the
filing of the Registration Statement nor the offering or sale of the Shares as
contemplated by this Agreement gives rise to any rights, other than those which
have been waived or satisfied, for or relating to the registration of any shares
of Common Stock.

            (d)   The information set forth under the caption "Capitalization"
in the Prospectus is true and correct. All of the Shares conform to the
description thereof contained in the Registration Statement. The form of
certificates for the Shares conforms to the corporate law of the jurisdiction of
the Company's incorporation.

            (e)   The Commission has not issued an order preventing or
suspending the use of any Prospectus relating to the proposed offering of the
Shares nor instituted proceedings for that purpose. The Registration Statement
contains, and the Prospectus and any amendments or supplements thereto will
contain, all statements which are required to be stated therein by, and will
conform to, the requirements of the Act and the Rules and Regulations. The
Registration Statement and any amendment thereto do not contain, and will not
contain, any untrue statement of a material fact and do not omit, and will not
omit, to state any material fact required to be stated therein or necessary to
make the statements therein not misleading. The Prospectus and any amendments
and supplements thereto do not contain, and will not contain, any untrue
statement of material fact; and do not omit, and will not omit, to state any
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; provided, however, that the Company makes no representations or
warranties as to information contained in or omitted from the Registration
Statement or the Prospectus, or any such amendment or supplement, in reliance
upon, and in conformity with, written information furnished to the Company by or
on behalf of any Underwriter through the Representatives, specifically for use
in the preparation thereof.

            (f)   The consolidated financial statements of the Company and the
Subsidiary, together with related notes and schedules as set forth in the
Registration Statement, present fairly



                                       3
<PAGE>   4

the financial position and the results of operations and cash flows of the
Company and the consolidated Subsidiary, at the indicated dates and for the
indicated periods. Such financial statements and related schedules have been
prepared in accordance with generally accepted principles of accounting,
consistently applied throughout the periods involved, except as disclosed
therein, and all adjustments necessary for a fair presentation of results for
such periods have been made. The summary financial and statistical data included
in the Registration Statement presents fairly the information shown therein and
such data has been compiled on a basis consistent with the financial statements
presented therein and the books and records of the Company.

            (g)   PricewaterhouseCoopers LLP, who have certified certain of the
financial statements filed with the Commission as part of the Registration
Statement, are independent public accountants as required by the Act and the
Rules and Regulations.

            (h)   There is no action, suit, claim or proceeding pending or, to
the knowledge of the Company, threatened against the Company or the Subsidiary
before any court or administrative agency or otherwise which if determined
adversely to the Company or the Subsidiary might result in any material adverse
change in the earnings, business, management, properties, assets, rights,
operations, condition (financial or otherwise) of the Company and of the
Subsidiary taken as a whole or to prevent the consummation of the transactions
contemplated hereby, except as set forth in the Registration Statement.

            (i)   The Company and the Subsidiary have good and marketable title
to all of the properties and assets reflected in the financial statements (or as
described in the Registration Statement) hereinabove described, subject to no
lien, mortgage, pledge, charge or encumbrance of any kind except those reflected
in such financial statements (or as described in the Registration Statement) or
which are not material in amount relative to the assets of the Company and the
Subsidiary taken as a whole. The Company and the Subsidiary occupy their leased
properties under valid and binding leases conforming in all material respects to
the description thereof set forth in the Registration Statement. The Company's
assets are adequate for the conduct of the Company's business as described in
the Registration Statement.

            (j)   Each of the Company and the Subsidiary has filed all Federal,
State, local and foreign tax returns which have been required to be filed and
have paid all taxes indicated by said returns and all assessments received by
them or either of them to the extent that such taxes have become due and are not
being contested in good faith and for which an adequate reserve for accrual has
been established in accordance with generally accepted accounting principles.
All tax liabilities have been adequately provided for in the financial
statements of the Company, and the Company does not know of any actual or
proposed additional material tax assessments.

            (k)   Since the respective dates as of which information is given in
the Registration Statement, as it may be amended or supplemented, there has not
been any material adverse change or any development involving a prospective
material adverse change in or affecting the earnings, business, management,
properties, assets, rights, operations, condition (financial or otherwise), of
the Company and the Subsidiary taken as a whole, whether or not



                                       4
<PAGE>   5

occurring in the ordinary course of business, and there has not been any
material transaction entered into by the Company or the Subsidiary, other than
transactions in the ordinary course of business and changes and transactions
described in the Registration Statement, as it may be amended or supplemented.
Neither the Company nor the Subsidiary has any material contingent obligations
which are not disclosed in the Registration Statement.

            (l)   Neither the Company nor the Subsidiary is or with the giving
of notice or lapse of time or both, will be, in violation of or in default under
its Charter or Bylaws or under any agreement, lease, contract, indenture or
other instrument or obligation to which it is a party or by which it, or any of
its respective properties, is bound and which default is of material
significance in respect of the business or financial condition of the Company
and the Subsidiary taken as a whole. The execution, delivery and performance of
this Agreement and the consummation of the transactions herein contemplated and
the fulfillment of the terms hereof do not and will not conflict with or result
in a breach of any of the terms or provisions of, or constitute a default under,
any indenture, mortgage, deed of trust or other agreement or instrument to which
the Company or the Subsidiary is a party, or of the Charter or Bylaws of the
Company or any order, rule or regulation applicable to the Company or the
Subsidiary of any court or of any regulatory body or administrative agency or
other governmental body having jurisdiction over the Company or the Subsidiary,
except where such conflict, breach, violation or default would not have a
material adverse effect on the business or financial condition of the Company
and the Subsidiary taken as a whole.

            (m)   Each approval, consent, order, authorization, designation,
declaration or filing by or with any regulatory, administrative or other
governmental body necessary in connection with the execution and delivery by the
Company of this Agreement and the consummation of the transactions herein
contemplated (except such additional steps as may be required by the Commission,
the National Association of Securities Dealers, Inc. (the "NASD") or such
additional steps as may be necessary to qualify the Shares for public offering
by the Underwriters under state securities or Blue Sky laws) has been obtained
or made and is in full force and effect.

            (n)   The Company and the Subsidiary hold all licenses, certificates
and permits from governmental authorities which are necessary to the conduct of
their businesses, except where the failure to have such licenses, certificates
or permits, either singly or in the aggregate, would not have a material adverse
effect on the business or financial condition of the Company; to the knowledge
of the Company, the Company and the Subsidiary each own or possess the right to
use all patents, patent rights, trademarks, trade names, service marks, service
names, copyrights, license rights, know-how (including trade secrets and other
unpatented and unpatentable proprietary or confidential information, systems or
procedures) and other intellectual property rights ("Intellectual Property")
necessary to carry on the business of the Company and the Subsidiary in all
material respects; except as specifically disclosed in the Prospectus neither
the Company nor the Subsidiary has infringed, or received notice of conflict
with, any Intellectual Property of any other person or entity. The Company has
taken all reasonable steps necessary to secure interests in such Intellectual
Property from its contractors. There are no outstanding options, licenses or
agreements of any kind relating to the Intellectual



                                       5
<PAGE>   6

Property of the Company that are required to be described in the Prospectus and
are not described in all material respects. The Company is not a party to or
bound by any options, licenses or agreements with respect to the Intellectual
Property of any other person or entity that are required to be set forth in the
Prospectus and are not described in all material respects. None of the
technology employed by the Company has been obtained or is being used by the
Company in violation of any contractual obligation binding on the Company or, to
the Company's knowledge, any of its officers, directors or employees or
otherwise in violation of the rights of any persons; the Company has not
received any written or oral communications alleging that the Company has
violated, infringed or conflicted with, or, by conducting its business as set
forth in the Prospectus, would violate, infringe or conflict with, any of the
Intellectual Property of any other person or entity. Except as specifically
disclosed in the Prospectus, the Company knows of no infringement by others of
Intellectual Property owned by or licensed to the Company.

            (o)   Neither the Company, nor to the Company's knowledge, any of
its affiliates, has taken or may take, directly or indirectly, any action
designed to cause or result in, or which has constituted or which might
reasonably be expected to constitute, the stabilization or manipulation of the
price of the shares of Common Stock to facilitate the sale or resale of the
Shares. The Company acknowledges that the Underwriters may engage in passive
market making transactions in the Shares on the Nasdaq Stock Market in
accordance with Regulation M under the Exchange Act.

            (p)   Neither the Company nor the Subsidiary is an "investment
company" within the meaning of such term under the Investment Company Act of
1940, as amended (the "1940 Act") and the rules and regulations of the
Commission thereunder.

            (q)   The Company maintains a system of internal accounting controls
sufficient to provide reasonable assurances that (i) transactions are executed
in accordance with management's general or specific authorization; (ii)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with generally accepted accounting principles and to
maintain accountability for assets; (iii) access to assets is permitted only in
accordance with management's general or specific authorization; and (iv) the
recorded accountability for assets is compared with existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences.

            (r)   Each of the Company and the Subsidiary carries, or is covered
by, insurance in such amounts and covering such risks as is adequate for the
conduct of its respective business and the value of its respective properties
and as is customary for companies engaged in similar industries.

            (s)   The Company is in compliance in all material respects with all
presently applicable provisions of the Employee Retirement Income Security Act
of 1974, as amended, including the regulations and published interpretations
thereunder ("ERISA"); no "reportable event" (as defined in ERISA) has occurred
with respect to any "pension plan" (as defined in ERISA) for which the Company
would have any liability; the Company has not incurred and does not expect to
incur liability under (i) Title IV of ERISA with respect to termination of, or



                                       6
<PAGE>   7

withdrawal from, any "pension plan" or (ii) Sections 412 or 4971 of the Internal
Revenue Code of 1986, as amended, including the regulations and published
interpretations thereunder (the "Code"); and each "pension plan" for which the
Company would have any liability that is intended to be qualified under Section
401(a) of the Code is so qualified in all material respects and nothing has
occurred, whether by action or by failure to act, which would cause the loss of
such qualification.

            (t)   To the Company's knowledge, there are no affiliations or
associations between any member of the NASD and any of the Company's officers,
directors or 5% or greater securityholders, except as set forth in the
Registration Statement.

            (u)   No material labor dispute with employees of the Company exists
or to the knowledge of the Company is threatened and the Company is not aware of
any existing, threatened or imminent labor disturbance by the employees of any

Company or the business, management, properties, assets, rights, operations of
the Company.

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

            (w)   No relationship, direct or indirect, exists between or among
the Company or the Subsidiary, on the one hand, and the directors, officers,
stockholders, customers or suppliers of the Company or the Subsidiary, on the
other hand, which is required to be described in the Registration Statement or
the Prospectus that is not so described.

            (x)   There are no outstanding loans, advances (except normal
advances for business expenses in the ordinary course of business) or guarantees
of indebtedness by the Company to or for the benefit of any of the officers or
directors of the Company or any of the members of any of them, except as
disclosed in the Registration Statement and the Prospectus.

            (y)   Neither the Company nor the Subsidiary, nor, to the Company's
knowledge, any director, officer, agent, employee or other person associated
with or acting on behalf of the Company or the Subsidiary, has (i) used any
corporate funds for any unlawful contribution, gift, entertainment or other
unlawful expense relating to political activity; (ii) made any direct or
indirect unlawful payment to any foreign or domestic government official or
employee from corporate funds; (iii) violated or is in violation of any
provisions of the Foreign Corrupt Practices Act of 1972; or (iv) made any bribe,

            (z)   The Company has not been advised, and has no reason to
believe, that it and each of its Subsidiaries are or the Subsidiary is not
conducting business in compliance with all applicable laws, rules and
regulations of the jurisdictions in which it is conducting business, except
where failure to be so in compliance would not materially adversely affect the
earnings, business, management, properties, assets, rights, operations or
prospects of the Company and the



                                       7
<PAGE>   8

Subsidiaries Subsidiary, taken as a whole.

            (aa)  To the Company's knowledge, the business, operations and
facilities of the Company and the Subsidiary have been and are being conducted
in compliance in all material respects with all applicable laws, ordinances,
rules, regulations, licenses, permits, approvals, plans, authorizations or
requirements relating to occupational safety and health, pollution, protection
of health or the environment (including, without limitation, those relating to
emissions, discharges, releases or threatened releases of pollutants,
contaminants or hazardous or toxic substances, materials or wastes into ambient
air, surface water, groundwater or land, or relating to the manufacture,
processing, distribution, use, treatment, storage, disposal, transport or
handling of chemical substances, pollutants, contaminants or hazardous or toxic
substances, materials or wastes, whether solid, gaseous or liquid in nature) or
otherwise relating to remediating real property in which the Company or the
Subsidiary has or had any interest, whether owned or leased, of any governmental
department, commission, board, bureau, agency or instrumentality of the United
States, any state or political subdivision thereof and all applicable judicial
or administrative agency or regulatory decrees, awards, judgments and orders
relating thereto, except for such failures to so comply as would not,
individually or in the aggregate, have a material adverse affect on the
Company's and the Subsidiary's earnings, business, management, properties,
assets, rights, operations, taken as a whole; and neither the Company nor the
Subsidiary has received any notice from a governmental instrumentality or any
third party alleging any violation thereof or liability thereunder (including,
without limitation, liability for costs of investigating or remediating sites
containing hazardous substances or damage to natural resources), except for such
violations or liabilities which would not, individually or in the aggregate,
have a material adverse affect on the Company's and the Subsidiary's earnings,
business, management, properties, assets, rights, operations, taken as a whole.

            (bb)  The Company has reviewed its operations and that of the
Subsidiary to evaluate the extent to which the business or operations of the
Company or the Subsidiary will be affected by the Year 2000 Problem. As a result
of such review, the Company has no reason to believe, and does not believe, that
the Year 2000 problem will have a material adverse effect on the financial
position, stockholders' equity or results of operations of the Company and the
Subsidiary or result in any material loss or interference with the Company's
business or operations. The "Year 2000 Problem" as used herein means any
significant risk that computer hardware or software used in the receipt,
transmission, processing, manipulation, storage, retrieval, retransmission or
other utilization of data or in the operation of mechanical or electrical
systems of any kind will not, in the case of dates or time periods occurring
after December 31, 1999, function at least as effectively as in the case of
dates or time periods occurring prior to January 1, 2000.

National Market, subject to official notice of issuance.

            (dd)  The Company has not distributed and will not distribute prior
to the later of (i) the Closing Date, or any date on which Option Shares are to
be purchased, as the case may



                                       8
<PAGE>   9

be, and (ii) completion of the distribution of the Shares, any offering material
in connection with the offering and sale of the Shares other than any
preliminary prospectuses, the Prospectus, the Registration Statement and other
materials, if any, permitted by the Act.

            (ee)  There are no contracts, agreements or understandings between
the Company and any person granting such person (i) the right to require the
Company to file a registration statement under the Act with respect to any
securities of the Company, except as disclosed in the Prospectus or (ii) to
require the Company to include such securities with the Shares registered
pursuant to the Registration Statement.

            (ff)  All agreements granting an option or right to purchase or
otherwise acquire Common Stock of the Company, including warrants and any other
security convertible into or exchangeable for Common Stock, and all agreements
pursuant to which any current stockholder has agreed to purchase Common Stock of
the Company, contain provisions prohibiting the sale, pledge, grant, transfer or
other disposition of such security for a period of 180 days after the effective
date of the Registration Statement.


      2.    PURCHASE, SALE AND DELIVERY OF THE FIRM SHARES.

            (a)   On the basis of the representations, warranties and covenants
herein contained, and subject to the conditions herein set forth, the Company
agrees to sell to the Underwriters and each Underwriter agrees, severally and
not jointly, to purchase, at a price of $_____ per share, the number of Firm
Shares set forth opposite the name of each Underwriter in Schedule I hereof,
subject to adjustments in accordance with Section 9 hereof.

            (b)   Payment for the Firm Shares to be sold hereunder is to be made
in New York Clearing House funds by Federal (same day) against delivery of
certificates therefor to the Representatives for the several accounts of the
Underwriters. Such payment and delivery are to be made through the facilities of
the Depository Trust Company, New York, New York at 10:00 a.m., New York time,
on the third business day after the date of this Agreement or at such other time
and date not later than five business days thereafter as you and the Company
shall agree upon, such time and date being herein referred to as the "Closing
Date." (As used herein, "business day" means a day on which the New York Stock
Exchange is open for trading and on which banks in New York are open for
business and are not permitted by law or executive order to be closed.)

            (c)   In addition, on the basis of the representations and
warranties herein contained and subject to the terms and conditions herein set
forth, the Company hereby grants an option to the several Underwriters to
purchase the Option Shares at the price per share as set forth in the first
paragraph of this Section 2. The option granted hereby may be exercised in whole
or in part by giving written notice (i) at any time before the Closing Date and
(ii) only once thereafter within 30 days after the date of this Agreement, by
you, as Representatives of the several Underwriters, to the Company setting
forth the number of Option Shares as to which the several Underwriters are
exercising the option, the names and denominations in which the Option Shares



                                       9
<PAGE>   10

are to be registered and the time and date at which such certificates are to be
delivered. The time and date at which certificates for Option Shares are to be
delivered shall be determined by the Representatives but shall not be earlier
than three nor later than 10 full business days after the exercise of such
option, nor in any event prior to the Closing Date (such time and date being
herein referred to as the "Option Closing Date"). If the date of exercise of the
option is three or more days before the Closing Date, the notice of exercise
shall set the Closing Date as the Option Closing Date. The number of Option
Shares to be purchased by each Underwriter shall be in the same proportion to
the total number of Option Shares being purchased as the number of Firm Shares
being purchased by such Underwriter bears to 4,00,000, adjusted by you in such
manner as to avoid fractional shares. The option with respect to the Option
Shares granted hereunder may be exercised only to cover over-allotments in the
sale of the Firm Shares by the Underwriters. You, as Representatives of the
several Underwriters, may cancel such option at any time prior to its expiration
by giving written notice of such cancellation to the Company. To the extent, if
any, that the option is exercised, payment for the Option Shares shall be made
on the Option Closing Date in Federal (same day funds) through the facilities of
the Depository Trust Company in New York, New York drawn to the order of the
Company.

      3.    OFFERING BY THE UNDERWRITERS.

            It is understood that the several Underwriters are to make a public
offering of the Firm Shares as soon as the Representatives deem it advisable to
do so. The Firm Shares are to be initially offered to the public at the initial
public offering price set forth in the Prospectus. The Representatives may from
time to time thereafter change the public offering price and other selling
terms. To the extent, if at all, that any Option Shares are purchased pursuant
to Section 2 hereof, the Underwriters will offer them to the public on the
foregoing terms.

            It is further understood that you will act as the Representatives
for the Underwriters in the offering and sale of the Shares in accordance with a
Master Agreement Among Underwriters entered into by you and the several other
Underwriters.

      4.    COVENANTS OF THE COMPANY.

            The Company covenants and agrees with the several Underwriters that:

            (a)   The Company will (i) use its best efforts to cause the
Registration Statement to become effective or, if the procedure in Rule 430A of
the Rules and Regulations is followed, to prepare and timely file with the
Commission under Rule 424(b) of the Rules and Regulations a Prospectus in a form
approved by the Representatives containing information previously omitted at the
time of effectiveness of the Registration Statement in reliance on Rule 430A of
the Rules and Regulations and (ii) not file any amendment to the Registration
Statement or supplement to the Prospectus of which the Representatives shall not
previously have been advised and furnished with a copy or to which the
Representatives shall have reasonably objected in writing or which is not in
compliance with the Rules and Regulations.

            (b)   The Company will advise the Representatives promptly (i) when
the



                                       10
<PAGE>   11

Registration Statement or any post-effective amendment thereto shall have become
effective, (ii) of receipt of any comments from the Commission, (iii) of any
request of the Commission for amendment of the Registration Statement or for
supplement to the Prospectus or for any additional information, and (iv) of the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement or the use of the Prospectus or of the institution of any
proceedings for that purpose. The Company will use its best efforts to prevent
the issuance of any such stop order preventing or suspending the use of the
Prospectus and to obtain as soon as possible the lifting thereof, if issued.

            (c)   The Company will cooperate with the Representatives in
endeavoring to qualify the Shares for sale under the securities laws of such
jurisdictions as the Representatives may reasonably have designated in writing
and will make such applications, file such documents, and furnish such
information as may be reasonably required for that purpose, provided the Company
shall not be required to qualify as a foreign corporation or to file a general
consent to service of process in any jurisdiction where it is not now so
qualified or required to file such a consent. The Company will, from time to
time, prepare and file such statements, reports, and other documents, as are or
may be required to continue such qualifications in effect for so long a period
as the Representatives may reasonably request for distribution of the Shares.

            (d)   The Company will deliver to, or upon the order of, the
Representatives, from time to time, as many copies of any Preliminary Prospectus
as the Representatives may reasonably request. The Company will deliver to, or
upon the order of, the Representatives during the period when delivery of a
Prospectus is required under the Act, as many copies of the Prospectus in final
form, or as thereafter amended or supplemented, as the Representatives may
reasonably request. The Company will deliver to the Representatives at or before
the Closing Date, four signed copies of the Registration Statement and all
amendments thereto including all exhibits filed therewith, and will deliver to
the Representatives such number of copies of the Registration Statement
(including such number of copies of the exhibits filed therewith that may
reasonably be requested), and of all amendments thereto, as the Representatives
may reasonably request.

            (e)   The Company will comply with the Act and the Rules and
Regulations, and the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), and the rules and regulations of the Commission thereunder, so as to
permit the completion of the distribution of the Shares as contemplated in this
Agreement and the Prospectus. If during the period in which a prospectus is
required by law to be delivered by an Underwriter or dealer, any event shall
occur as a result of which, in the judgment of the Company or in the reasonable
opinion of the Underwriters, it becomes necessary to amend or supplement the
Prospectus in order to make the statements therein, in the light of the
circumstances existing at the time the Prospectus is delivered to a purchaser,
not misleading, or, if it is necessary at any time to amend or supplement the
Prospectus to comply with any law, the Company promptly will prepare and file
with the Commission an appropriate amendment to the Registration Statement or
supplement to the Prospectus so that the Prospectus as so amended or
supplemented will not, in the light of the circumstances when it is so
delivered, be misleading, or so that the Prospectus will comply with the law.



                                       11
<PAGE>   12

            (f)   The Company will make generally available to its security
holders, as soon as it is practicable to do so, but in any event not later than
15 months after the effective date of the Registration Statement, an earning
statement (which need not be audited) in reasonable detail, covering a period of
at least 12 consecutive months beginning after the effective date of the
Registration Statement, which earning statement shall satisfy the requirements
of Section 11(a) of the Act and Rule 158 of the Rules and Regulations and will
advise you in writing when such statement has been so made available.

            (g)   Prior to the Closing Date, the Company will furnish to the
Underwriters, as soon as they have been prepared by or are available to the
Company, a copy of any unaudited interim financial statements of the Company for
any period subsequent to the period covered by the most recent financial
statements appearing in the Registration Statement and the Prospectus.

            (h)   No offering, sale, short sale or other disposition of any
shares of Common Stock of the Company or other securities convertible into or
exchangeable or exercisable for shares of Common Stock or derivative of Common
Stock (or agreement for such) will be made for a period of 180 days after the
date of this Agreement, directly or indirectly, by the Company otherwise than
hereunder or with the prior written consent of Deutsche Bank Securities Inc.,
except (i) the Company's issuance of Common Stock upon the exercise of warrants
and stock options that are presently outstanding and described as such in the
Prospectus, or any other issuance of options of Common Stock hereafter under the
option or equity incentive plans described in the Prospectus, provided that no
such issuance of Common Stock results from any acceleration of vesting of any
such security, and (ii) the Company's issuance of Common Stock under the
employee stock purchase plan described in the Prospectus.

            (i)   The Company will use its best efforts to list, subject to
notice of issuance, the Shares on the Nasdaq National Market.

            (j)   The Company has caused each officer and director of the
Company and each beneficial owner of the issued and outstanding shares of
capital stock of the Company (including shares of Common Stock which may be
deemed to be owned on the date hereof in accordance with the rules and
regulations of the Commission, shares of Common Stock of the Company which may
be issued upon exercise of a stock option or warrant, and any other security
convertible into or exchangeable for Common Stock) to furnish to you, on or
prior to the date of this agreement, a letter or letters, in form and substance
satisfactory to the Underwriters, pursuant to which each such person shall agree
not to offer, sell, sell short or otherwise dispose of any shares of Common
Stock of the Company or other capital stock of the Company, or any other

            (k)   The Company shall enforce the provisions referenced in Section

                                       12
<PAGE>   13

hereof prohibiting the sale, pledge, grant, transfer or other disposition of the
Company's securities for a period of 180 days after the effective date of the
Registration Statement, unless Deutsche Bank Securities Inc. has given prior
written consent authorizing such sale, pledge, grant, transfer or other
disposition of the Company's securities.

            (l)   The Company shall apply the net proceeds of its sale of the
Shares substantially as set forth in the Prospectus and shall file such reports
with the Commission with respect to the sale of the Shares and the application
of the proceeds therefrom as may be required in accordance with Rule 463 under
the Act.

            (l)   The Company shall not invest, or otherwise use the proceeds
received by the Company from its sale of the Shares in such a manner as would
require the Company or any of its subsidiaries to register as an investment
company under the 1940 Act.

            (m)   The Company will maintain a transfer agent and, if necessary
under the jurisdiction of incorporation of the Company, a registrar for the
Common Stock.

            (n)   The Company will not take, directly or indirectly, any action
designed to cause or result in, or that has constituted or might reasonably be
expected to constitute, the stabilization or manipulation of the price of any
securities of the Company.

      5.    COSTS AND EXPENSES.

            The Company will pay all costs, expenses and fees incident to the
performance of the obligations of the Company under this Agreement, including,
without limiting the generality of the foregoing, the following: accounting fees
of the Company; the fees and disbursements of counsel for the Company; the cost
(exclusive of fees and expenses of counsel to the Underwriters except as
provided below) of printing and delivering to, or as requested by, the
Underwriters copies of the Registration Statement, Preliminary Prospectuses, the
Prospectus, this Agreement, the Underwriters' Selling Memorandum, the
Underwriters' Invitation Letter, the Listing Application, the Blue Sky Survey
and any supplements or amendments thereto; the filing fees of the Commission;
the filing fees and expenses (including legal fees and disbursements) incident

disbursements of counsel for the Underwriters incurred in connection with the
qualification of the Shares under State securities or Blue Sky laws. The Company
agrees to pay all costs and expenses of the Underwriters, including the fees and
disbursements of counsel for the Underwriters, incident to the offer and sale of
the Directed Shares other than the fees and expenses of counsel to the
Underwriters and Underwriters' discounts, concessions and commissions associated
therewith. The Company shall not, however, be required to pay for any of the
Underwriters expenses (other than those related to qualification under NASD
regulation and State securities or Blue Sky laws) except that, if this Agreement
shall not be consummated because the conditions in Section 6 hereof are not
satisfied, or because this Agreement is terminated by the Representatives
pursuant to Section 11 hereof, or by reason of any failure, refusal or inability
on the part of the Company to perform any undertaking or



                                       13
<PAGE>   14

satisfy any condition of this Agreement or to comply with any of the terms
hereof on its part to be performed, unless such failure to satisfy said
condition or to comply with said terms be due to the default or omission of any
Underwriter, then the Company shall reimburse the several Underwriters for
reasonable out-of-pocket expenses, including fees and disbursements of counsel,
reasonably incurred in connection with investigating, marketing and proposing to
market the Shares or in contemplation of performing their obligations hereunder;
but the Company shall not in any event be liable to any of the several
Underwriters for damages on account of loss of anticipated profits from the sale
by them of the Shares.

      6.    CONDITIONS OF OBLIGATIONS OF THE UNDERWRITERS.

            The several obligations of the Underwriters to purchase the Firm
Shares on the Closing Date and the Option Shares, if any, on the Option Closing
Date are subject to the accuracy, as of the Closing Date or the Option Closing
Date, as the case may be, of the representations and warranties of the Company
contained herein, and to the performance by the Company of its covenants and
obligations hereunder and to the following additional conditions:

            (a)   The Registration Statement and all post-effective amendments
thereto shall have become effective and any and all filings required by Rule 424
and Rule 430A of the Rules and Regulations shall have been made, and any request
of the Commission for additional information (to be included in the Registration
Statement or otherwise) shall have been disclosed to the Representatives and
complied with to their reasonable satisfaction. No stop order suspending the
effectiveness of the Registration Statement, as amended from time to time, shall
have been issued and no proceedings for that purpose shall have been taken or,
to the knowledge of the Company, shall be contemplated by the Commission and no
injunction, restraining order, or order of any nature by a Federal or state
court of competent jurisdiction shall have been issued as of the Closing Date
which would prevent the issuance of the Shares.

            (b)   The Representatives shall have received on the Closing Date or
the Option Closing Date, as the case may be, the opinion of Wilson Sonsini
Goodrich & Rosati, counsel for the Company, dated the Closing Date or the Option
Closing Date, as the case may be, addressed to the Underwriters (and stating
that it may be relied upon by counsel to the Underwriters) to the effect that:

                  (i)    The Company has been duly organized and is validly
existing as a corporation in good standing under the laws of the State of
Delaware, with corporate power and authority to own or lease its properties and
conduct its business as described in the Registration Statement; the Subsidiary
has been duly organized and is validly existing as a corporation in good
standing under the laws of the jurisdiction of its incorporation, with corporate
power and authority to own or lease its properties and conduct its business as
described in the Registration Statement; each of the Company and the Subsidiary
is duly qualified to transact business in all jurisdictions in which the conduct
of its business requires such qualification, or in which the failure to qualify
would have a materially adverse effect upon the business of the Company and the
Subsidiary taken as a whole; the outstanding shares of capital stock of the
Subsidiary have been duly authorized and validly issued and are fully paid and
non-assessable and are owned by



                                       14
<PAGE>   15

the Company and no options, warrants or other rights to purchase, agreements or
other obligations to issue or other rights to convert any obligations into any
shares of capital stock or of ownership interests in the Subsidiary are
outstanding.

                  (ii)   The Company has authorized and outstanding capital
stock as set forth under the caption "Capitalization" in the Prospectus; the
authorized shares of the Company's Common Stock have been duly authorized; the
outstanding shares of the Company's Common Stock have been duly authorized and
validly issued and are fully paid and non-assessable; the shares of Common Stock
to be issued upon conversion of the Preferred Stock immediately prior to the
closing of the offering of the Shares have been duly authorized and when issued
will be validly issued, fully paid and non-assessable; the authorized capital
stock of the Company and all of the Shares conform to the description thereof
contained in the Prospectus; the certificates for the Shares, assuming they are
in the form filed with the Commission, are in due and proper form; the shares of
Common Stock, including the Option Shares, if any, to be sold by the Company
pursuant to this Agreement have been duly authorized and will be validly issued,
fully paid and non-assessable upon the closing of the offering of the Shares and
payment for such Shares as contemplated by this Agreement; none of such Shares
will be issued in violation of any preemptive right contained in the Company's
Charter of Bylaws or, to such counsel's knowledge any contractual right of first
refusal; and, to such counsel's knowledge, the Shares will not be subject to any
such preemptive rights or rights of first refusal.

                  (iii)  Except as described in or contemplated by the
Prospectus, to the knowledge of such counsel, there are no outstanding
securities of the Company convertible or exchangeable into or evidencing the
right to purchase or subscribe for any shares of capital stock of the Company
and there are no outstanding or authorized options, warrants or rights of any
character obligating the Company to issue any shares of its capital stock or any
securities convertible or exchangeable into or evidencing the right to purchase
or subscribe for any shares of such stock; and except as described in the
Prospectus, to the knowledge of such counsel, no holder of any securities of the
Company or any other person has the right, contractual or otherwise, which has
not been satisfied or effectively waived, to cause the Company to sell or
otherwise issue to them, or to permit them to underwrite the sale of, any of the
Shares or the right to have any shares of Common Stock or other securities of
the Company included in the Registration Statement or the right, as a result of
the filing of the Registration Statement, to require registration under the Act
of any shares of Common Stock or other securities of the Company.

                  (iv)   Based solely upon the oral advice of the staff of the
Commission, the Registration Statement has become effective under the Act and,
to the best of the knowledge of such counsel, no stop order proceedings with
respect thereto have been instituted or are pending or threatened under the Act.

                  (v)    The Registration Statement, the Prospectus and each
amendment or supplement thereto comply as to form in all material respects with
the requirements of the Act, and the applicable rules and regulations thereunder
(except that such counsel need express no



                                       15
<PAGE>   16

opinion as to the financial statements and related notes and schedules and other
financial and statistical data included therein).

                  (vi)   The statements under the captions "Management,"
"Certain Transactions," "Description of Capital Stock," and "Shares Eligible for
Future Sale" in the Prospectus and Items 14 and 15 of the Registration
Statement, insofar as such statements constitute a summary of legal documents
referred to therein or of matters of law, fairly summarize in all material
respects the information called for with respect to such documents and matters.

                  (vii)  Such counsel does not know of any contracts or
documents required to be filed as exhibits to the Registration Statement or
described in the Registration Statement or the Prospectus which are no so filed
or described as required, and such contracts and documents as are summarized in
the Registration Statement or the Prospectus are fairly summarized in all
material respects.

                  (viii) Such counsel knows of no material legal or governmental
proceedings pending or threatened against the Company or any the Subsidiary
except as set forth in the Prospectus.

                  (ix)   The execution, delivery and performance of this
Agreement and the consummation of the transactions herein contemplated do not
and will not conflict with or result in a breach of any of the terms or
provisions of, or constitute a default under, the Charter or Bylaws of the
Company, or any agreement or instrument known to such counsel to which the
Company or the Subsidiary is a party or by which the Company or the Subsidiary
may be bound.

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

                  (xi)   No approval, consent, order, authorization,
designation, declaration or filing by or with any regulatory, administrative or
other governmental body is necessary in connection with the execution and
delivery of this Agreement and the consummation of the transactions herein
contemplated (other than as may be required by the NASD or as required by State
securities and Blue Sky laws as to which such counsel need express no opinion)
except such as have been obtained or made, specifying the same.

                  (xii)  The Company is not, and will not become, as a result of
the consummation of the transactions contemplated by this Agreement, and
application of the net proceeds therefrom as described in the Prospectus,
required to register as an investment company under the 1940 Act.

      The opinions expressed by Wilson Sonsini Goodrich & Rosati may be limited
in all respects to existing laws of the State of California, the General
Corporation Law of the State of Delaware (based solely on such counsel's review
of standard compilations of such law and without reference to its conflict of
law rules) and applicable federal laws. With respect to the



                                       16
<PAGE>   17

matters above relating to the Subsidiary, such counsel shall be entitled to rely
on the opinions expressed by foreign counsel to the Subsidiary.

      In addition, to the matters set forth above, such counsel shall also
include statements to the effect that such counsel has participated in the
preparation of the Registration Statement and the Prospectus, involving, among
other things, review and discussion of the contents thereof, discussion and
inquiries concerning various legal matters and the review of certain records,
documents and proceedings, and participation in conferences with certain
officers and other representatives of the Company, including its independent
accountants, and with the Underwriters and Underwriters' counsel at which the
contents of the Registration Statement and the Prospectus were discussed, but
without independent check or verification of the accuracy or completeness of
such information, except as specified in such opinion, and that on the basis of
such consideration, review and discussion, but without independent check or
verification, nothing has come to such counsel's attention which leads such
counsel to believe (i) that, as of its effective date, the Registration
Statement or any further amendment thereto made by the Company prior to the date
hereof (other than the financial statements and related schedules and financial
and statistical data therein, as to which such counsel need not express any
belief) contained an untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading (ii) that as of its date, the Prospectus or any further
amendment or supplement thereto made by the Company prior to the date hereof
(other than the financial statements and related schedules and financial and
statistical data therein, as to which such counsel need not express any belief)
contained an untrue statement of a material fact or omitted to state a material
fact necessary to make the statements therein, in light of the circumstances in
which they were made, not misleading or (iii) that, as of the date of such
opinion, either the Registration Statement or the Prospectus or any further
amendment or supplement thereto made by the Company prior to the date of such
opinion (other than the financial statements, and related schedules and
financial and statistical data therein, as to which such counsel need not
express any belief) contains an untrue statement of a material fact or omits to
state a material fact necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading.

            (c)   The Representatives shall have received from Morrison &
Foerster LLP, counsel for the Underwriters, an opinion dated the Closing Date or
the Option Closing Date, as the case may be, substantially to the effect
specified in subparagraphs (iv) and (v) of Paragraph (b) of this Section 6, the
due organization and valid existence of the Company under the laws of the State
of Delaware and the validity of the Shares, and the Company shall have furnished
to such counsel such documents as such counsel may reasonably request for the
purpose of passing upon such matters. In rendering such opinion Morrison &
Foerster LLP may rely as to all matters governed other than by the laws of the
State of Delaware, California or Federal laws on the opinion of counsel referred
to in Paragraph (b) of this Section 6. In addition to the matters set forth
above, such opinion shall also include a statement to the effect that nothing
has come to the attention of such counsel which leads them to believe that (i)
the Registration Statement, or any amendment thereto, as of the time it became
effective under the Act (but after giving effect to any modifications
incorporated therein pursuant to Rule 430A under the Act) and as of the Closing
Date or the Option Closing Date, as the case may be, contained an untrue
statement of a



                                       17
<PAGE>   18

material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein not misleading, and (ii) the
Prospectus, or any supplement thereto, on the date it was filed pursuant to the
Rules and Regulations and as of the Closing Date or the Option Closing Date, as
the case may be, contained an untrue statement of a material fact or omitted to
state a material fact, necessary to make the statements therein, in the light of
the circumstances under which they were made, not misleading (except that such
counsel need express no view as to financial statements, related notes and
schedules and other financial and statistical information therein). With respect
to such statement, Morrison & Foerster LLP may state that their belief is based
upon the procedures set forth therein, but is without independent check and
verification.

            (d)   The Representatives shall have received at or prior to the
Closing Date from Morrison & Foerster LLP a memorandum or summary, in form and
substance satisfactory to the Representatives, with respect to the qualification
for offering and sale by the Underwriters of the Shares under the State
securities or Blue Sky laws of such jurisdictions as the Representatives may
reasonably have designated to the Company.

            (e)   You shall have received, on each of the dates hereof, the
Closing Date and the Option Closing Date, as the case may be, a letter dated the
date hereof, the Closing Date or the Option Closing Date, as the case may be, in
form and substance satisfactory to you, of PricewaterhouseCoopers LLP confirming
that they are independent public accountants within the meaning of the Act and
the applicable published Rules and Regulations thereunder and stating that in
their opinion the financial statements and schedules examined by them and
included in the Registration Statement comply in form in all material respects
with the applicable accounting requirements of the Act and the related published
Rules and Regulations; and containing such other statements and information as
is ordinarily included in accountants' "comfort letters" to Underwriters with
respect to the financial statements and certain financial and statistical
information contained in the Registration Statement and Prospectus.

            (f)   The Representatives shall have received on the Closing Date or
the Option Closing Date, as the case may be, a certificate or certificates of
the Chief Executive Officer and the Chief Financial Officer of the Company to
the effect that, as of the Closing Date or the Option Closing Date, as the case
may be, each of them severally represents as follows:

                  (i)    The Registration Statement has become effective under
the Act and no stop order suspending the effectiveness of the Registration
Statement has been issued, and no proceedings for such purpose have been taken
or are, to his knowledge, contemplated by the Commission;

                  (ii)   The representations and warranties of the Company
contained in Section 1 hereof are true and correct as of the Closing Date or the
Option Closing Date, as the case may be;

                  (iii)  All filings required to have been made pursuant to
Rules 424 or 430A under the Act have been made;



                                       18
<PAGE>   19

                  (iv)   He has carefully examined the Registration Statement
and the Prospectus and, in his opinion, as of the effective date of the
Registration Statement, the statements contained in the Registration Statement
were true and correct, and such Registration Statement and Prospectus did not
omit to state a material fact required to be stated therein or necessary in
order to make the statements therein not misleading, and since the effective
date of the Registration Statement, no event has occurred which should have been
set forth in a supplement to or an amendment of the Prospectus which has not
been so set forth in such supplement or amendment; and

                  (v)    Since the respective dates as of which information is
given in the Registration Statement and Prospectus, there has not been any
material adverse change or any development involving a prospective material
adverse change in or affecting the condition, financial or otherwise, of the
Company and the Subsidiary taken as a whole or the earnings, business,
management, properties, assets, rights, operations, condition (financial or
otherwise) of the Company and the Subsidiary taken as a whole, whether or not
arising in the ordinary course of business.

            (g)   The Company shall have furnished to the Representatives such
further certificates and documents confirming the representations and
warranties, covenants and conditions contained herein and related matters as the
Representatives may reasonably have requested.

            (h)   The Firm Shares and Option Shares, if any, have been approved
for designation upon notice of issuance on the Nasdaq National Market.

            (i)   The Lockup Agreements described in Section 4(j) are in full
force and effect.

            The opinions and certificates mentioned in this Agreement shall be
deemed to be in compliance with the provisions hereof only if they are in all
material respects satisfactory to the Representatives and to Morrison & Foerster
LLP, counsel for the Underwriters.

            If any of the conditions hereinabove provided for in this Section 6
shall not have been fulfilled when and as required by this Agreement to be
fulfilled, the obligations of the Underwriters hereunder may be terminated by
the Representatives by notifying the Company of such termination in writing or
by telegram at or prior to the Closing Date or the Option Closing Date, as the
case may be.

            In such event, the Company and the Underwriters shall not be under
any obligation to each other (except to the extent provided in Sections 5 and 8
hereof).

      7.    CONDITIONS OF THE OBLIGATIONS OF THE COMPANY.

            The obligations of the Company to sell and deliver the portion of
the Shares required to be delivered as and when specified in this Agreement are
subject to the conditions that at the



                                       19
<PAGE>   20

Closing Date or the Option Closing Date, as the case may be, no stop order
suspending the effectiveness of the Registration Statement shall have been
issued and in effect or proceedings therefor initiated or threatened.

      8.    INDEMNIFICATION.

            (a)   The Company agrees:

                  (1)   To indemnify and hold harmless each Underwriter and each
person, if any, who controls any Underwriter within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act, against any losses, claims, damages
or liabilities to which such Underwriter or any such controlling person may
become subject under the Act, the Exchange Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) arise out of or are based upon (i) any untrue statement or alleged
untrue statement of any material fact contained in the Registration Statement,
any Preliminary Prospectus, the Prospectus or any amendment or supplement
thereto, (ii) the omission or alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or (iii) any alleged act or failure to act by any Underwriter in
connection with, or relating in any manner to, the Shares or the offering
contemplated hereby, and which is included as part of or referred to in any
loss, claim, damage, liability or action arising out of or based upon matters
covered by clause (i) or (ii) above (provided, that the Company shall not be
liable under this clause (iii) to the extent that it is determined in a final
judgment by a court of competent jurisdiction that such loss, claim, damage,
liability or action resulted directly from any such acts or failures to act
undertaken or omitted to be taken by such Underwriter through its gross
negligence or willful misconduct); provided, however, that the Company will not
be liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement, or omission or alleged omission made in the Registration Statement,
any Preliminary Prospectus, the Prospectus or such amendment or supplement, in
reliance upon and in conformity with written information furnished to the
Company by or through the Representatives specifically for use in the
preparation thereof or resulting from the failure by the Underwriters to provide
an amended Registration Statement, Preliminary Prospectus or Prospectus to
prospective investors in the Company's Common Stock.

                  (2)   To reimburse each Underwriter and each such controlling
person upon demand for any legal or other out-of-pocket expenses reasonably
incurred by such Underwriter or such controlling person in connection with
investigating or defending any such loss, claim, damage or liability, action or
proceeding or in responding to a subpoena or governmental inquiry related to the
offering of the Shares, whether or not such Underwriter or controlling person is
a party to any action or proceeding. In the event that it is finally judicially
determined that the Underwriters were not entitled to receive payments for legal
and other expenses pursuant to this subparagraph, the Underwriters will promptly
return all sums that had been advanced pursuant hereto.

                  (3)   To indemnify and hold harmless Deutsche Bank and each
person,



                                       20
<PAGE>   21

if any, who controls, or is controlled by, Deutsche Bank within the meaning of
Section 15 of the Act and Section 20 of the Exchange Act (the "Deutsche Bank
Entities"), against any losses, claims, damages or liabilities to which such
Underwriter or any such controlling person may become subject under the Act or
the Exchange Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of or are
based upon (i) any untrue statement or alleged untrue statement of any material
fact contained in any material prepared by or with the consent of the Company
for distribution to Participants in connection with the Directed Share Program,
(ii) the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading
(iii) caused by the failure of any Participant to pay for and accept delivery of
Directed Shares that the Participant agreed to purchase or (iv) any alleged act
or failure to act by any Deutsche Bank Entity in connection with, or relating in
any manner to, the Directed Share Program, other than any loss, claim, damage,
liability or action that are finally judicially determined to have resulted from
the bad faith, gross negligence or material misstatement or omission of any
material fact on the part any Deutsche Bank Entity; provided, however, that the
Company will not be liable in any such case to the extent that any such loss,
claim, damage or liability arises out of or is based upon an untrue statement or
alleged untrue statement, or omission or alleged omission made in the
Registration Statement, any Preliminary Prospectus, the Prospectus, or such
amendment or supplement, in reliance upon and in conformity with written
information furnished to the Company by or through the Representatives
specifically for use in the preparation thereof.

                  (4)   To reimburse each Deutsche Bank Entity upon demand for
any legal or other out-of-pocket expenses reasonably incurred by such Deutsche
Bank in connection with investigating or defending any such loss, claim, damage
or liability, action or proceeding or in responding to a subpoena or
governmental inquiry related to the offering of the Directed Shares, whether or
not such Deutsche Bank Entity is a party to any action or proceeding. In the
event that it is finally judicially determined that the Deutsche Bank Entities
were not entitled to receive payments for legal and other expenses pursuant to
this subparagraph, the Deutsche Bank Entities will promptly return all sums that
had been advanced pursuant hereto.

            (b)   Each Underwriter severally and not jointly will indemnify and
hold harmless the Company, each of its directors, each of its officers who have
signed the Registration Statement, and each person, if any, who controls the
Company within the meaning of the Act, against any losses, claims, damages or
liabilities to which the Company or any such director, officer or controlling
person may become subject under the Act or otherwise, insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
arise out of or are based upon (i) any untrue statement or alleged untrue
statement of any material fact contained in the Registration Statement, any
Preliminary Prospectus, the Prospectus or any amendment or supplement thereto,
or (ii) the omission or the alleged omission to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading in the light of the circumstances under which they were made; and
will reimburse any legal or other expenses reasonably incurred by the Company or
any such director, officer, or controlling person in connection with
investigating or defending any such loss, claim, damage, liability, action or
proceeding; provided, however, that each Underwriter will be liable in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or



                                       21
<PAGE>   22

alleged omission has been made in the Registration Statement, any Preliminary
Prospectus, the Prospectus or such amendment or supplement, in reliance upon and
in conformity with written information furnished to the Company by or through
the Representatives specifically for use in the preparation thereof. This
indemnity agreement will be in addition to any liability which such Underwriter
may otherwise have.

            (c)   In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to this Section 8, such person (the
"indemnified party") shall promptly notify the person against whom such
indemnity may be sought (the "indemnifying party") in writing. No
indemnification provided for in Section 8(a) or (b) shall be available to any
party who shall fail to give notice as provided in this Section 8(c) if the
party to whom notice was not given was unaware of the proceeding to which such
notice would have related and was materially prejudiced by the failure to give
such notice, but the failure to give such notice shall not relieve the
indemnifying party or parties from any liability which it or they may have to
the indemnified party for contribution or otherwise than on account of the
provisions of Section 8(a) or (b). In case any such proceeding shall be brought
against any indemnified party and it shall notify the indemnifying party of the
commencement thereof, the indemnifying party shall be entitled to participate
therein and, to the extent that it shall wish, jointly with any other
indemnifying party similarly notified, to assume the defense thereof, with
counsel satisfactory to such indemnified party and shall pay as incurred the
fees and disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own counsel
at its own expense. Notwithstanding the foregoing, the indemnifying party shall
pay as incurred (or within 30 days of presentation) the reasonable fees and
expenses of the counsel retained by the indemnified party in the event (i) the
indemnifying party and the indemnified party shall have mutually agreed to the
retention of such counsel, (ii) the named parties to any such proceeding
(including any impleaded parties) include both the indemnifying party and the
indemnified party and representation of both parties by the same counsel would
be inappropriate due to actual or potential differing interests between them or
(iii) the indemnifying party shall have failed to assume the defense and employ
counsel acceptable to the indemnified party within a reasonable period of time
after notice of commencement of the action. It is understood that the
indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the reasonable fees and
expenses of more than one separate firm for all such indemnified parties. Such
firm shall be designated in writing by you in the case of parties indemnified
pursuant to Section 8(a) and by the Company in the case of parties indemnified
pursuant to Section 8(b). The indemnifying party shall not be liable for any
settlement of any proceeding effected without its written consent but if settled
with such consent or if there be a final judgment for the plaintiff, the
indemnifying party agrees to indemnify the indemnified party from and against
any loss or liability by reason of such settlement or judgment. In addition, the
indemnifying party will not, without the prior written consent of the
indemnified party, settle or compromise or consent to the entry of any judgment
in any pending or threatened claim, action or proceeding of which
indemnification may be sought hereunder (whether or not any indemnified party is
an actual or potential party to such claim, action or proceeding) unless such
settlement, compromise or consent includes an unconditional release of each
indemnified party from all liability arising out of such claim, action or
proceeding.

            (d)   If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless an indemnified party under
Section 8(a)(1), (a)(2) or (b) above in respect of any losses, claims, damages
or liabilities (or actions or proceedings in respect thereof) referred to
therein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) in such proportion as
is appropriate to reflect the relative benefits received by the Company on the
one hand and the Underwriters on the other from the offering of the Shares. If,
however, the allocation provided by the immediately preceding sentence is not
permitted by applicable law then each indemnifying party shall contribute to
such amount paid or payable by such indemnified party in such proportion as is
appropriate to reflect not only such relative benefits but also the relative
fault of the Company on the one hand and the Underwriters on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages or liabilities, (or actions or proceedings in respect thereof),
as well as any other relevant equitable considerations. The relative benefits
received by the Company on the one hand and the Underwriters on the other shall
be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover page of the Prospectus. The relative
fault shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
on the one hand or the Underwriters on the other and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

            The Company and the Underwriters agree that it would not be just and
equitable if contributions pursuant to this Section 8(d) were determined by pro
rata allocation (even if the Underwriters were treated as one entity for such
purpose) or by any other method of allocation which does not take account of the
equitable considerations referred to above in this Section 8(d). The amount paid
or payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to above in
this Section 8(d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (d), (i) no Underwriter shall be required to contribute any amount in
excess of the underwriting discounts and commissions applicable to the Shares
purchased by such Underwriter, and (ii) no person guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation. The Underwriters' obligations in this Section 8(d) to
contribute are several in proportion to their respective underwriting
obligations and not joint.

            (e)   If the indemnification provided for in this Section 8 is
unavailable to or insufficient to hold harmless a Deutsche Bank Entity under
Section 8(a)(3) or(a)(4) above in respect of any losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) referred to therein,
then the Company shall contribute to the amount paid or payable by such Deutsche
Bank Entity as a result of such losses, claims, damages or liabilities (or
actions or



                                       23
<PAGE>   24

proceedings in respect thereof) in such proportion as is appropriate to reflect
the relative benefits received by the Company on the one hand and the Deutsche
Bank Entity on the other from the offering of the Directed Shares. If, however,
the allocation provided by the immediately preceding sentence is not permitted
by applicable law then the Company shall contribute to such amount in such
proportion as is appropriate to reflect not only such relative benefits but also
the relative fault of the Company on the one hand and the Deutsche Bank Entity
on the other in connection with the statements or omissions which resulted in
such losses, claims, damages or liabilities, (or actions or proceedings in
respect thereof),as well as any other relevant equitable considerations. The
relative benefits received by the Company on the one hand and the Deutsche Bank
Entities on the other shall be deemed to be in the same proportion as the total
net proceeds from the offering of the Directed Shares (before deducting
expenses) received by the Company bear to the total underwriting discounts and
commissions received by the Deutsche Bank Entity in connection therewith. The
relative fault shall be determined by reference to, among other things, whether
the untrue or alleged untrue statement of a material fact or the omission or
alleged omission to state a material fact relates to information supplied by the
Company on the one hand or the Deutsche Bank Entity on the other and the
parties' relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission.

            The Company and the Deutsche Bank Entities agree that it would not
be just and equitable if contributions pursuant to this Section 8(e) were
determined by pro rata allocation (even if the Deutsche Bank Entities were
treated as one entity for such purpose) or by any other method of allocation
which does not take account of the equitable considerations referred to above in
this Section 8(e). The amount paid or payable by a Deutsche Bank Entity as a
result of the losses, claims, damages or liabilities (or actions or proceedings
in respect thereof) referred to above in this Section 8(e) shall be deemed to
include any legal or other expenses reasonably incurred by such Deutsche Bank
Entity in connection with investigating or defending any such action or claim.
Notwithstanding the provisions of this subsection (e), (i) no Deutsche Bank
Entity shall be required to contribute any amount in excess of the underwriting
discounts and commissions applicable to the Directed Shares purchased by such
Deutsche Bank Entity, and (ii) no Deutsche Bank Entity guilty of fraudulent
misrepresentation (within the meaning of Section 11(f) of the Act) shall be
entitled to contribution from any person who was not guilty of such fraudulent
misrepresentation.

            (f)   In any proceeding relating to the Registration Statement, any
Preliminary Prospectus, the Prospectus or any supplement or amendment thereto,
each party against whom contribution may be sought under this Section 8 hereby
consents to the jurisdiction of any court having jurisdiction over any other
contributing party, agrees that process issuing from such court may be served
upon him or it by any other contributing party and consents to the service of
such process and agrees that any other contributing party may join him or it as
an additional defendant in any such proceeding in which such other contributing
party is a party.

            (g)   Any losses, claims, damages, liabilities or expenses for which
an indemnified party is entitled to indemnification or contribution under this
Section 8 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 8



                                       24
<PAGE>   25

and the representations and warranties of the Company set forth in this
Agreement shall remain operative and in full force and effect, regardless of (i)
any investigation made by or on behalf of any Underwriter or any person
controlling any Underwriter, the Company, its directors or officers or any
persons controlling the Company, (ii) acceptance of any Shares and payment
therefor hereunder, and (iii) any termination of this Agreement. A successor to
any Underwriter, or to the Company, its directors or officers, or any person
controlling the Company, shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 8.

      9.    DEFAULT BY UNDERWRITERS.

            If on the Closing Date or the Option Closing Date, as the case may
be, any Underwriter shall fail to purchase and pay for the portion of the Shares
which such Underwriter has agreed to purchase and pay for on such date
(otherwise than by reason of any default on the part of the Company), you, as
Representatives of the Underwriters, shall use your reasonable efforts to
procure within 36 hours thereafter one or more of the other Underwriters, or any
others, to purchase from the Company such amounts as may be agreed upon and upon
the terms set forth herein, the Firm Shares or Option Shares, as the case may
be, which the defaulting Underwriter or Underwriters failed to purchase. If
during such 36 hours you, as such Representatives, shall not have procured such
other Underwriters, or any others, to purchase the Firm Shares or Option Shares,
as the case may be, agreed to be purchased by the defaulting Underwriter or
Underwriters, then (a) if the aggregate number of shares with respect to which
such default shall occur does not exceed 10% of the Firm Shares or Option
Shares, as the case may be, covered hereby, the other Underwriters shall be
obligated, severally, in proportion to the respective numbers of Firm Shares or
Option Shares, as the case may be, which they are obligated to purchase
hereunder, to purchase the Firm Shares or Option Shares, as the case may be,
which such defaulting Underwriter or Underwriters failed to purchase, or (b) if
the aggregate number of shares of Firm Shares or Option Shares, as the case may
be, with respect to which such default shall occur exceeds 10% of the Firm
Shares or Option Shares, as the case may be, covered hereby, the Company or you
as the Representatives of the Underwriters will have the right, by written
notice given within the next 36-hour period to the parties to this Agreement, to
terminate this Agreement without liability on the part of the non-defaulting
Underwriters or of the Company except to the extent provided in Section 8
hereof. In the event of a default by any Underwriter or Underwriters, as set
forth in this Section 9, the Closing Date or Option Closing Date, as the case
may be, may be postponed for such period, not exceeding seven days, as you, as
Representatives, may determine in order that the required changes in the
Registration Statement or in the Prospectus or in any other documents or
arrangements may be effected. The term "Underwriter" includes any person
substituted for a defaulting Underwriter. Any action taken under this Section 9
shall not relieve any defaulting Underwriter from liability in respect of any
default of such Underwriter under this Agreement.

      10.   NOTICES.

            All communications hereunder shall be in writing and, except as
otherwise provided herein, will be mailed, delivered, telecopied or telegraphed

      11.   TERMINATION.

            (a)   This Agreement may be terminated by you by notice to the
Company at any time prior to the Closing Date if any of the following has
occurred: (i) since the respective dates as of which information is given in the
Registration Statement and the Prospectus, any material adverse change or any
development which is reasonably expected to have material adverse change in or
affecting the condition, financial or otherwise, of the Company and the
Subsidiary taken as a whole or the earnings, business, management, properties,
assets, rights, operations, condition (financial or otherwise) of the Company
and the Subsidiary taken as a whole, whether or not arising in the ordinary
course of business, (ii) any outbreak or escalation of hostilities or
declaration of war or national emergency or other national or international
calamity or crisis or change in economic or political conditions if the effect
of such outbreak, escalation, declaration, emergency, calamity, crisis or change
on the financial markets of the United States would, in your reasonable
judgment, make it impracticable or inadvisable to market the Shares or to
enforce contracts for the sale of the Shares, or (iii) suspension of trading in
securities generally on the New York Stock Exchange or the American Stock
Exchange or limitation on prices (other than limitations on hours or numbers of
days of trading) for securities on either such Exchange, (iv) the enactment,
publication, decree or other promulgation of any statute, regulation, rule or
order of any court or other governmental authority which in your opinion
materially and adversely affects or may materially and adversely affect the
business or operations of the Company, (v) declaration of a banking moratorium
by United States or New York State authorities, (vi) the suspension of trading
of the Company's common stock by the Nasdaq Stock Market, the Commission, or any
other governmental authority or (vii) the taking of any action by any
governmental body or agency in respect of its monetary or fiscal affairs which
in your reasonable opinion has a material adverse effect on the securities
markets in the United States; or

            (b)   as provided in Sections 6 and 9 of this Agreement.

      12.   SUCCESSORS.

            This Agreement has been and is made solely for the benefit of the
Underwriters and the Company and their respective successors, executors,
administrators, heirs and assigns, and the officers, directors and controlling
persons referred to herein, and no other person will have any right or
obligation hereunder. No purchaser of any of the Shares from any Underwriter
shall be deemed a successor or assign merely because of such purchase.

            The reimbursement, indemnification and contribution agreements
contained in this Agreement and the representations, warranties and covenants in
this Agreement shall remain in full force and effect regardless of (a) any
termination of this Agreement, (b) any investigation made by or on behalf of any
Underwriter or controlling person thereof, or by or on behalf of the Company or
its directors or officers and (c) delivery of and payment for the Shares under
this Agreement.

            This Agreement may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
