                               PROSPECTUS SUMMARY

  This summary highlights information contained elsewhere in this prospectus.
This summary does not contain all the information you should consider before
buying shares in the offering. You should read the entire prospectus carefully.
Unless otherwise indicated, this prospectus assumes that 1) the underwriters
have not exercised their option to purchase additional shares, 2) all shares of
preferred stock have been automatically converted into shares of common stock
and 3) the sale of 788,438 shares of common stock in a private placement will
close at the same time as this offering at an assumed public offering price of
$15.00.

  As used in this prospectus, references to we, our, us and CrossWorlds refer
to CrossWorlds Software, Inc., its predecessors and its consolidated
subsidiaries and not to the underwriters.

                           CrossWorlds Software, Inc.

 Who We Are

  We provide e-business infrastructure software that enables the integration
and automation of business processes within companies and among their customers
and suppliers using the Internet. Our products help traditional and new
businesses use the Internet to reduce information technology costs, increase
productivity, improve responsiveness to customer demands and enhance overall
competitiveness.

 Our Market

  We believe that the market for e-business infrastructure software is
comprised of the market for e-business software and the related market for
enterprise application integration software. We believe that many of the
software products offered by participants in these markets lack key elements of
a complete e-business infrastructure solution. Examples of these missing
elements include: 1) business process support, 2) architectural flexibility and
3) the ability to support e-business strategies.

 Our Products

  We provide pre-built connectivity solutions for common technology
environments and leading e-business and enterprise applications. We offer pre-
built business process modules to support many of the common integration
requirements of companies in our target markets. Our products are based on a
scalable architecture that meets the integration requirements of large
companies and trading networks. We also provide a set of tools that allow our
customers to customize their integration solution to address their unique e-
business requirements.

 Our Strategy

  Our product strategy is to expand our support for e-business applications and
technologies, build connectivity for additional enterprise applications and
expand our set of pre-built business process integration modules. Our sales
strategy is to sell our products to companies in selected industries, including
technology, industrial manufacturing, process manufacturing and
telecommunications. We intend to expand our partnerships with IBM, SAP AG and
global systems integrators through technology sharing and cooperative marketing
and sales to support our strategies. We expect our systems integrator partners
to provide an increasing portion of the implementation services for our
products.

 Our Customers

  Since late 1997, when we shipped our first product, we have licensed our
products to 48 customers, including Applied Materials, Inc., Delphi Automotive
Systems, E.I. DuPont de Nemours and Company, Ingersoll-Rand Company, Nortel
Networks Corporation, Siemens AG, Solar Turbines, Inc., a wholly owned
subsidiary of Caterpillar Inc., and U S WEST.

                                  RISK FACTORS

  You should carefully consider the risks and uncertainties described below
before making an investment decision. Any of the risks described below could
seriously harm our business, financial condition or operating results. This
could cause the trading price of our common stock to decline, and you may lose
all or part of your investment.

                  Risks Related to CrossWorlds' Business

Because of our limited operating history, it is difficult for us to predict and
plan for challenges. As a result, our future performance may be harmed.

  We were incorporated in March 1996 and shipped our first products in November
1997. Because our operating history is limited, our future operating results
and our future stock price are difficult to predict. We may not foresee trends
that may emerge and harm our business, and we cannot forecast operating
expenses based on our historical results. It is also difficult to plan to meet
the challenges we face in the future, specifically:

  . expanding our customer base;

  . competing effectively with: 1) internal information technology
    departments of potential customers, 2) systems integrators that develop
    customized solutions and 3) other software vendors that offer e-business
    infrastructure products; and

  . managing expanding operations--specifically our ability to install
    management information and control systems in an efficient and timely
    manner.

Also, there is little financial data that you can use to evaluate our business.


We have a history of losses, we expect future losses, and we may never achieve
profitability.

  We have experienced operating losses in each quarterly and annual period
since March 1996. Despite our history of losses, we believe it is vital to our
future success that we increase our research and development and sales and
marketing expenses. These additional expenses contribute to our losses and
require that we increase our revenue to achieve profitability. We incurred a
net loss of $15.5 million from March 1996 through December 31, 1997 against
revenue of $1.1 million. We incurred a net loss of $41.4 million for the year
ended December 31, 1998 against revenue of $7.7 million. We incurred a net loss
of $38.2 million for the year ended December 31, 1999 against revenue of $19.1
million. At December 31, 1999, we had an accumulated deficit of approximately
$95.1 million. We may not be able to increase our revenue in the future. As a
result, we expect to incur significant losses in the future, and we may never
achieve profitability.

Because our quarterly revenue fluctuates significantly due to the nature of our
sales cycles, we may disappoint investors' expectations or may not fulfill the
expectations of the financial markets or financial analysts, which could cause
our stock price to decline.

  Our sales cycle causes unpredictable fluctuations in our revenue which could
adversely affect the value of your investment. Our sales cycle varies typically
from two to nine months because:

  .  our e-business infrastructure solutions are expensive, with a median
     selling price of approximately $530,000 comprised of licensing fees and
     service fees;

  .  our products are complex and to generate sales we must spend a
     significant amount of time educating our potential customers about the
     uses and benefits of our products; and

  .  some of our prospective customers evaluate our products on a trial basis
     before entering a sales contract.


                                       7
<PAGE>


This lengthy sales cycle makes it difficult to predict the quarter in which
expected orders will occur. Delays in the execution of orders could cause some
or all of the licensing fee revenue from those orders to be shifted from the
expected quarter to a subsequent quarter or quarters.

Because our quarterly revenue fluctuates significantly due to the nature of our
product implementations, we may disappoint investors, which could cause our
stock price to decline.

  We generally recognize license revenue from orders on a percentage-of-
completion basis as the customer reaches milestones in their implementation of
our products. We also recognize services revenue as we perform implementation
services. As a consequence, the timing of our revenue depends on the continued
progress of our customers' implementation cycles. Each customer has unique
integration requirements and, because our products are complex, we must
integrate a variety of enterprise applications in each implementation. Our
product implementation schedules can take three to nine months or more and span
multiple quarterly periods. We may fail to achieve continued progress on
anticipated implementation schedules. Our customers may delay, suspend or
terminate their implementation efforts. If either of the above happens, we may
not recognize the expected revenue on these orders until subsequent quarters,
if at all.

Because a substantial majority of our revenue has been derived from a small
number of selected industries, a decline in demand for our software in these
industries could hurt our operations.

  We derive a large majority of our revenue to date from sales of our software
and related services to customers in the telecommunications industry and the
manufacturing industry. Any significant decline in the demand for, and market
acceptance of, our software in these industries could hurt the results of our
operations. As of March 31, 2000, we had 48 customers. 22 customers are in the
manufacturing industry and 15 customers are in the telecommunications industry.
Sales of products to customers in the manufacturing and telecommunications
industries accounted for approximately 72% of our revenue in 1997,
approximately 96% of our revenue in 1998 and approximately 90% of our revenue
in 1999. We expect that sales of our software and related services to customers
in these industries will account for a majority of our revenue over the next
twelve months.

We derive our revenue from a small number of customers, and our revenue could
decline if we lose a major customer.

  We have generated a substantial portion of our revenue from a limited number
of customers. We expect that a small number of customers will continue to
account for a substantial portion of our revenue. Many of our current customers
will continue to provide a substantial portion of our revenue through
additional license, implementation services and maintenance fees. In 1999, one
customer accounted for more than 21% of our revenue and six customers
collectively accounted for more than 50% of our revenue. The loss of even one
customer could have a material adverse effect on our revenue.

If we are unable to increase software license revenue as a proportion of our
overall revenue, our gross margins and profitability could be harmed.

  We believe that increasing our software license revenue as a proportion of
overall revenue is essential to achieve and maintain profitability. To achieve
this goal, we plan to further develop our relationships with systems
integrators to have them perform a majority of the consulting services for our
products. If we are unable to adequately train systems integrators to provide
services for our products, or if systems integrators do not devote resources to
providing services for our products, it will be significantly more difficult
for us to increase software license revenue as a portion of overall revenue,
thus limiting our ability to increase gross margins and profitability.

                                       8
<PAGE>



Our revenue will likely decline or slow if we do not develop and maintain
successful relationships with systems integrators.

  We engage in joint sales, marketing and implementation efforts with a number
of systems integrators including Deloitte Consulting, PricewaterhouseCoopers
and CSC Consulting. In many cases, these parties have extensive relationships
with our existing and potential customers and influence the decisions of these
customers. We rely upon these firms to: 1) recommend our products during the
evaluation stage of the purchasing process, 2) to refer prospective customers
to us and 3) to provide access to customers' executive-level decision makers.
If systems integrators are not appropriately trained to implement our products,
our reputation with existing and prospective customers could be harmed. Our
failure to establish or maintain these relationships could significantly harm
our ability to license and successfully implement our e-business infrastructure
software products. Our competitors may have stronger relationships with some
systems integrators and as a result, those systems integrators may be more
likely to recommend competitors' products.

If we are unable to compete in the market for business integration solutions,
we may lose sales and may be forced to lower our prices, which would cause a
decline in our revenue.

  The market for our products is intensely competitive. It is expected to
become increasingly competitive as current competitors enhance and expand their
product offerings and new competitors enter the market. Competition could
result in: 1) price reductions, 2) reduced gross margins and 3) loss of market
share; any one of which could significantly reduce our future revenues. Our
current competitors include a number of companies offering alternative e-
business infrastructure solutions.

  To date, we have faced competition from:

  .  internal information technology departments of potential customers;

  .  systems integrators and other information technology service providers;
     and

  .  software vendors targeting one or more segments of our market including
     Vitria Technology, Inc., Software Technologies Corporation and TIBCO
     Software, Inc.

  It is also possible that alliances among competitors or new competitors,
including Oracle Corporation, Microsoft or IBM, may emerge and rapidly acquire
significant market share.

We depend on technology licensed to us by third parties. If we lose our right
to use licensed technology, our revenue could be harmed and our costs could
increase.

  Our software products incorporate technology licensed to us by third parties,
currently BEA Systems, IBM and Inprise/Borland Corporation, which provides
important messaging and other functionality. We depend on these third parties
to deliver and support reliable products, and to enhance their products in
response to industry trends and other technological changes. Any interruption
in the supply of our licensed software or increases in the pricing of these
licenses could harm our business by disrupting our operations, increasing our
costs, delaying our sales and hindering our ability to support our existing
customers.

                              Industry Risks

The loss of, or inability to attract, senior management and other key personnel
could harm our business and decrease the value of your investment.

  Our future success depends on the skills, experience and performance of our
senior management team and other key personnel, and their ability to operate
effectively, both individually and as a group. The intense competition for
qualified personnel in our industry and geographic region could harm our
ability to replace any of the members of our senior management team if we were
to lose their services in the future. If we do not succeed in attracting new
management and key personnel, or retaining and motivating existing management
and key personnel, our business will be harmed. In particular, the services and
expertise of our senior management team could be difficult to replace.

                                       9
<PAGE>


Our success depends upon our sales, consulting, support and technical
personnel. If we fail to attract and retain these personnel, our business may
be unable to grow and revenues could decline.

  If we fail to retain and sufficiently expand our direct sales force, or our
consulting, customer support and technical staffs, we may not be able to
increase revenue or achieve increased market acceptance of our products. To
date, we have sold our products primarily through our direct sales force and
have supported our customers through our consulting and customer support staff.
Our technical personnel develop and maintain our new products and product
enhancements. We believe that attracting and retaining these personnel is
particularly difficult for us because: 1) the market for e-business
infrastructure software is still emerging, 2) market acceptance of our products
has not yet been achieved, 3) the sales cycles for our products are lengthy and
4) we must constantly produce new products and product enhancements to compete.
Also, the high demand for qualified technical personnel in the San Francisco
metropolitan area makes it difficult to attract and retain technical personnel.

Our recent growth has strained our existing resources. Any failure to manage
this growth may harm the value of your investment.

  Our recent growth has strained, and future growth may continue to strain, our
personnel, management systems and resources, which could harm our business. To
effectively manage and support our operations, we will be required to:

  . integrate, train, motivate and manage our work force;

  . continue to improve our operational, financial and management controls,
    reporting systems and procedures; and

  . maintain close coordination among our executive, engineering, accounting,
    finance, marketing, sales and operations organizations.

If we fail to manage and support our operations, our business would be harmed
and our operating losses could increase.

  We have grown from 111 employees as of December 31, 1997 to 202 employees as
of December 31, 1999. As of December 31, 1999, we have also opened 14 sales
offices and established five foreign subsidiaries. Three of our eight executive
officers, specifically: 1) our president and chief executive officer, 2) senior
vice president global services and 3) senior vice president worldwide sales,
joined us within the last 6 months. Thus, they have limited prior experience
working together, and may not be effective working together.

  If expenditures related to the expansion of our operations are not
accompanied or shortly followed by significantly increased revenue, our losses
could be even greater than expected until we are able to delay or reduce these
expenditures. For example, during 1998 we increased our operating expenses
significantly, particularly sales and marketing expenses, based on our
expectations of revenue growth that did not materialize as quickly as
anticipated. These increased expense levels harmed our operating results for
that period.

Our international operations are expensive and challenging. If our
international operations do not perform as projected, our operating losses may
increase.

  We have committed significant resources to the opening of international
offices and the expansion of international sales and support channels in
advance of revenue. We expect to incur expenses for localizing our software for
foreign markets. If our international expansion strategy does not generate
sufficient revenue to offset these expenditures, our operating losses may
increase. Revenues from international sales represented: 1) 20% of total 1997
revenue, 2) 28% of total 1998 revenue and 3) 22% of total 1999 revenue.

                                       10
<PAGE>


  We have limited experience in marketing, selling and distributing our
products and services internationally. In December 1998, we implemented
strategic decisions to cease our Asian and Australian operations because our
capital expenditures in those markets were not producing sufficient returns. As
we expand our international operations, we may allow payment in foreign
currencies and exposure to losses in foreign currency transactions would
increase as a result.

If we fail to adapt to the rapid technological change which characterizes our
market, we could lose market share or our products could become obsolete.

  The market for e-business infrastructure software is characterized by:

    . rapid technological change;

    . frequent new product introductions and enhancements;

    . uncertain product life cycles;

    . changing customer requirements; and

    . evolving industry standards including Extensible Markup Language, or
      XML, and Secure Sockets Layer, or SSL.

The introduction of products embodying new technologies and the emergence of
new industry standards could quickly make our existing products obsolete and
unmarketable, which could harm our revenue. Our future success depends upon our
ability to develop and introduce a variety of new products and product
enhancements to address the increasingly sophisticated needs of our customers.

If our products do not work with multiple hardware, software and networking
platforms, some customers will not buy our products, and our revenue will
decline.

  We currently serve a customer base with a wide variety of constantly changing
hardware, software and networking platforms. If we are unable to provide and
support our products on these multiple platforms, some customers will not buy
our products and our business would be hurt. We may have lost potential sales
due to our products' inability to support multiple hardware and software
platforms.

If we are unable to build and maintain relationships with application software
vendors, we could be unable to create and maintain our connectivity products
and our revenue could be harmed.

  We have relationships with a number of application software vendors including
SAP, Oracle Corporation, Siebel Systems, Clarify Inc., Portal Software, Inc.,
and MetaSolv Software, Inc. These vendors provide access to their software and
documentation which enables us to develop connectivity solutions that are
compatible with their products. If these relationships are terminated or
restricted, or we are unsuccessful in establishing relationships with other
vendors, our ability to develop connectivity solutions to integrate new and
existing versions of these vendors' packaged enterprise applications would be
harmed.


Defects in or slow performance of our software products could diminish demand
for our products and cause costly liability, which would adversely affect our
operating results.

  Our software products may contain undetected errors or defects, especially
when first introduced or when new versions are released. Any errors, defects or
slow performance that is discovered could result in:

    . loss of revenue;

    . delay in market acceptance;

    . diversion of development resources;

    . distraction of management;

                                       11
<PAGE>


    . damage to our customer relationships or reputation;

    . increased service and warranty cost; or

    . costly litigation defense.

We have previously discovered errors in our software after shipping the
software. These errors, when discovered by our customers, have impaired our
customer relationships. Any defects and errors found in our products could
cause customers to seek damages for loss of data, lost revenue, systems costs
or other harm they may suffer. These damages may be high because our software
products are critical to our customers' business operations. A successful
product liability claim brought against us could harm our business.

The cost and difficulties of implementing our products could significantly harm
our reputation, which may diminish our revenues.

  Our products are often implemented as part of complex, time consuming and
expensive projects. Some of our customers have experienced delays and
difficulties in implementing our products. Prolonged delays and difficulties
have impaired our customer relationships. In many cases, our customers must
interact with, modify or replace significant elements of their existing
computer systems. This complicates the implementation process. If our customers
are dissatisfied with the implementation process, our ability to license
further products to these customers could be harmed. Dissatisfied customers may
refuse to recommend our products to prospective customers.

Because our products could interfere with our customers' other software
applications and hardware, we may be subject to claims by these customers,
which may be costly and may not be adequately covered by insurance.

  Our e-business infrastructure products are integrated with our customers'
other software and their networks. Customers or others may bring product
liability or warranty claims based on damage to, or interference with, these
networks or applications. Any of these claims could result in costly litigation
or divert management's attention and resources. Our current insurance coverage
would likely be insufficient to protect us from all liability that may be
imposed under these types of claims.

Our failure to safeguard our intellectual property could reduce our revenues,
or cause us to incur costly litigation.

  The value of our software products arises from the intellectual property in
those products. We rely primarily on a combination of: 1) patents, 2)
copyrights, 3) trademarks, 4) trade secret laws and 5) contractual obligations
with employees and third parties to protect the proprietary aspects of our
technology. The legal protection is limited. Unauthorized parties may copy
aspects of our products and obtain and use information that we believe is
proprietary. Other parties may breach confidentiality agreements or other
protective contracts they have made with us. The laws of many foreign countries
do not protect our intellectual property rights to the same extent as the laws
of the United States. Litigation may be necessary to enforce our intellectual
property rights. Intellectual property litigation has an uncertain outcome and
could result in substantial costs and diversion of management's attention and
resources.

Because our market is new, competitive and dependent upon intellectual property
rights, we could face costly litigation brought by third parties for
infringement of their rights.

  We may be subject to legal proceedings and claims for alleged infringement of
third party proprietary rights, including patents, trademarks or copyrights.
Any litigation could result in substantial costs and diversion of management's
attention and resources. Parties making infringement claims against us may
obtain judgments against us, which could prevent us from selling our products
or require us to enter into royalty or license agreements which are not
advantageous to us.

                              Offering Risks

Our stock price may be volatile because of the stock price volatility of other
companies in our industry and because our stock has not been publicly traded
before, and, as a result, you may lose all or part of your investment.

  The market price of our common stock is likely to be highly volatile. This
volatility could be caused by fluctuation of market valuations of significant
companies in our industry. The volatility could also be caused by the market
struggling to arrive at a valuation for our newly marketed stock. Equity
markets, particularly the market for high-technology companies, have recently
experienced significant price and volume fluctuations that are unrelated to the
operating performance of individual companies. Volatility in our stock price
may cause you to lose all or part of your investment.

The cost of possible securities class action litigation could increase our
expenses and damage our reputation with prospective and existing customers.

  Securities class action litigation has often been instituted against
companies following periods of volatility in the market price of their
securities. Litigation could result in substantial costs and a diversion of
management's attention and resources.

Our executive officers and directors own a large percentage of our voting stock
and could delay or prevent a change in our corporate control or other matters
requiring stockholder approval, even if favored by our other stockholders.

  Immediately after this offering, our executive officers and directors, and
their affiliates, will continue to own approximately 46.51% of our outstanding
common stock. These stockholders may be able to exert significant influence
over matters requiring approval by our stockholders, including the election of
directors and the approval of mergers or other business combinations. This
concentration of voting power could have the effect of delaying or preventing a
change in control that other stockholders view as favorable.


Investors in this offering will experience immediate and substantial dilution
and will pay a higher price for our common stock than our existing stockholders
paid.

  Purchasers of the common stock in the offering and private placement will
suffer an immediate and substantial dilution of $12.35 per share in the net
tangible book value of our common stock from an assumed initial public offering
price of $15.00 per share. The exercise of options with further dilute your
investment.

Approximately twenty million four hundred eighty five thousand, or 84%, of our
total outstanding shares are restricted from immediate resale but may be sold
into the market in the near future. This could cause the market price of our
common stock to drop significantly, even if our business is doing well.

  After this offering, we will have outstanding 24,485,001 shares of common
stock. This includes the 4,000,000 we are selling in this offering, which may
be resold in the public market immediately. The remaining 84%, or 20,485,001
shares, of our total outstanding shares will become available for resale in the
public market as shown in the chart below.

  As restrictions on resale end, the market price could drop significantly if
the holders of these restricted shares sell them or are perceived by the market
as intending to sell them.

                     YOU SHOULD NOT RELY ON FORWARD-LOOKING
                STATEMENTS BECAUSE THEY ARE INHERENTLY UNCERTAIN

  This prospectus contains forward-looking statements that involve risks and
uncertainties. We use words such as anticipates, believes, plans, expects,
future, intends and similar expressions to identify forward-looking statements.
This prospectus also contains forward-looking statements attributed to third
parties relating to their estimates of the growth of various markets. You
should not place undue reliance on these forward-looking statements, which
apply only as of the date of this prospectus. Our actual results could differ
materially from those anticipated in these forward-looking statements for many
reasons, including the risks to our business described in this prospectus.

  We are under no duty to update any of the forward-looking statements after
the date of this prospectus to conform these statements to actual results.

                                USE OF PROCEEDS

  We estimate that the net proceeds from the sale of the 4,000,000 shares of
common stock that we are selling in this offering and from a private placement
of 788,438 shares of common stock that will close at the same time as this
offering will be approximately $65.6 million. We estimate net proceeds of $74.0
million if the underwriters' option to purchase additional shares is exercised
in full. These figures are based upon an offering price of $15.00 per share and
deduct the underwriting discount and estimated offering expenses.

  We currently expect to use the net proceeds primarily for:

  .  working capital,

  .  general corporate purposes,

  .  increased sales and marketing expenditures,

  .  increased research and development expenditures, and

  .  capital expenditures made in the ordinary course of business.

We intend, if the opportunity arises, to use an unspecified portion of the net
proceeds to acquire or invest in complementary businesses, products and
technologies.

  Before these uses, we intend to invest the net proceeds from this offering in
short-term, interest-bearing, investment-grade securities.

                                DIVIDEND POLICY

  We have never declared or paid cash dividends on our capital stock. We
currently intend to retain any future earnings to fund the development and
growth of our business and consequently do not anticipate paying any cash
dividends. Our credit facility with Silicon Valley Bank prohibits us from
paying dividends without the bank's prior approval.

 Additional Share Information

  The outstanding share information in the table above is as of December 31,
1999 and excludes:

  . 6,793,436 shares of common stock issuable upon the exercise of
    outstanding options at a weighted average exercise price of $5.78 per
    share;

  . 343,431 shares of common stock issuable upon the exercise of outstanding
    warrants at a weighted average exercise price of $6.32 per share; and

  . 423,612 shares reserved for future issuance under our 1997 stock option
    plan and 640,475 shares reserved for future issuance under our 1999
    executive stock plan.

 Share Reserves

  Our board of directors, after December 31, 1999, approved changes to our
stock option plan reserves. On the effective date of this offering, the shares
reserved for future issuance under our stock option plans will be:

  . 1997 stock plan: 3,000,000 shares.

  . 2000 employee stock purchase plan: 750,000 shares.

  . 2000 directors' stock option plan: 300,000 shares.

The share reserves replace any stock option reserves existing immediately
before the effective date of the offering. These reserves totalled 1,064,087
shares on December 31, 1999.

                                    DILUTION

  As of December 31, 1999, our pro forma net tangible book deficit was
approximately $(726,000) or $(0.04) per share of common stock after giving
effect for the conversion of all outstanding shares of convertible preferred
into 16,542,628 shares of common stock. Pro forma net tangible book deficit per
share is equal to the total amount of our tangible assets minus our total
liabilities divided by the number of shares of our common stock outstanding.
This formula can be represented by:

                   total tangible assets -- total liabilities
                       shares of common stock outstanding

  After giving effect to the receipt of the estimated net proceeds from the
sale of 788,438 shares of common stock in a private placement that will close
at the same time as this offering and the sale of 4,000,000 shares of common
stock in this offering at an assumed initial public offering price of $15.00
per share, our pro forma, as adjusted net tangible book value at December 31,
1999 would have been approximately $64.9 million or $2.65 per share of common
stock. This represents an immediate increase in net tangible book value of
$2.69 per share to existing stockholders and an immediate dilution of $12.35
per share to new investors. This table illustrates this per share dilution:

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

Overview

 Business

  We provide e-business infrastructure software that enables the integration
and automation of business processes within enterprises and among their
customers and suppliers using the Internet. Our products help businesses use
the Internet to reduce information technology costs, increase productivity,
improve responsiveness to customer demands and enhance overall competitiveness.

 Historical spending

  We were incorporated in March 1996 and released our first product in November
1997. Since March 1996, we have incurred substantial research and development
costs, invested heavily in our sales, marketing and professional services
organizations and have expanded our global operations and corporate
infrastructure to support our long-term growth strategy. We have also made
substantial investments in marketing and in building strategic partnerships.
Our full-time employees increased from 111 as of December 31, 1997 to 202 as of
December 31, 1999. Because our expenditures have been much higher than our
revenue, we have incurred net losses in each fiscal quarter since March 1996.
At December 31, 1999, we had an accumulated deficit of $95.1 million. We
anticipate that our operating expenses will continue to increase as we expand
our product lines and sales and marketing efforts. We expect to incur net
losses at least through the end of 2001.

 Revenues

  Revenues to date have been derived from the sale of our e-business
infrastructure software and from maintenance and support, consulting and
training services. Customers who license our software generally purchase
maintenance contracts, typically covering a twelve month period. Customers may
also purchase consulting services, which are customarily billed by us at a
fixed daily rate plus out-of-pocket expenses. We also offer training services
that are billed on a per student or per class session basis. The initial total
orders from end-user customers, including licenses and services, have ranged
from just under $100,000 to over $6.0 million.

 Revenue recognition policy

  Our software arrangements typically involve significant customization or
implementation services. As a result, software license revenue is generally
recognized using the percentage-of-completion method over the project
implementation cycles, which typically range from three to nine months. In
circumstances where we are unable to estimate the amount of effort required to
customize or implement the software, software license revenue is recognized
using the completed contract method. To date, we have not encountered any
circumstances where we have been unable to estimate the amount of effort
required to customize or implement our software.

  In the future, we may recognize revenues for projects implemented by our
systems integrator partners upon shipment when our services are not essential
to the functionality of the software. Consulting and service revenue is
recognized as the services are performed. Maintenance revenue from customer
support and product upgrades, including maintenance bundled with original
software licenses, are deferred and recognized ratably over the term of the
maintenance agreement. When we enter into software arrangements with resellers,
we do not recognize revenue until the reseller demonstrates it has an
arrangement with the end user that satisfies our revenue recognition criteria.
Our revenue recognition policy complies with the American Institute of
Certified Public Accountants', AICPA, Statement of Position (SOP) 97-2,
Software Revenue Recognition.

                                       20
<PAGE>


 Revenue mix

  As a result of our revenue recognition policy, which requires us to defer
recognition of services revenue and other revenue not received for software
licenses, the mix of license, service and other revenue for the current quarter
does not necessarily reflect the mix in sales activities for the current
quarter. For example, revenues recognized during the quarter ended December 31,
1999 generally resulted from sales made during the first two quarters of fiscal
1999. We expect the future revenue mix to be more reflective of our current
period sales mix, which has been weighted more heavily towards software
licenses than previous quarters. Because our sales mix for the current quarter
has been weighted more heavily towards software license revenue, as opposed to
service and other revenue, than in previous quarters, we expect that in the
future our revenue mix for a particular quarter will more closely reflect our
sales mix in that quarter.

 Sales efforts and strategic relationships

  Our sales to date have been primarily generated by our direct sales force,
with a small percentage derived from indirect channels. In an effort to
increase sales and provide additional skilled implementation resources to our
customers, we have established relationships with third-party systems
integrators including Cap Gemini, CSC, Deloitte Consulting, EDS, Ernst & Young
and PricewaterhouseCoopers. In June 1999, CrossWorlds and IBM announced a
strategic relationship focused on joint marketing and cooperative sales of a
combined product offering.

  We established an international presence in mid-1997 by opening a sales
office in Germany. We subsequently opened sales offices in the United Kingdom
and France in 1998. Revenues from international sales represented 20% of total
1997 revenue, 28% of total 1998 revenue and 22% of total 1999 revenue. The
percentage decrease during the year ended December 31, 1999 was due to
significant revenue contribution from five U.S.-based customers, collectively
accounting for greater than 48% of total revenue during the period.

 Accounts receivable days sales outstanding

  Because of our revenue recognition policy, we calculate accounts receivable
days sales outstanding, DSO, as the total amount of our accounts receivable at
the end of a quarter divided by our revenue for the quarter plus the net change
in our current deferred revenue at the end of a quarter, multiplied by 90. This
formula can be represented as:

                        quarter-end accounts receivable

                                                     X 90
     quarterly revenue + net change in quarter-end current deferred revenue

We believe this calculation is appropriate because license fees are typically
billable regardless of whether revenue has been recognized or deferred. Under
this method, DSO was 102 days as of December 31, 1999. Since the terms of some
of our sales agreements spread our billings over the applicable project
implementation cycle and our sales activity is concentrated at the end of each
quarter, we anticipate that our DSO will continue to be substantial in future
periods. Although our DSO calculation may not be comparable to other similarly
titled information from other companies, we believe that it is an additional
meaningful measure of liquidity.

 Deferred compensation

  In 1998 and 1999, we issued stock options to employees at exercise prices
that were subsequently judged to have been below fair value. We recognized the
difference between the exercise prices and the later judged fair values as
deferred stock-based compensation. We amortize deferred stock-based
compensation over the vesting period of the related award as a non-cash expense
in compliance with Financial Accounting Standards Board Interpretation No. 28.
As of December 31, 1999, $2.5 million in deferred stock-based compensation
remained on our balance sheet which will be amortized to the consolidated
statements of operations through the first quarter of 2002.

 Danger of period-to-period comparisons of results

  In view of the rapidly changing nature of our business and our limited
operating history, we believe that period-to-period comparisons of revenue and
operating results are not necessarily meaningful and should not be relied upon
as indications of future performance. Additionally, despite our revenue growth,
we do not believe that historical growth rates are necessarily sustainable or
indicative of future growth.

total revenue.

Years Ended December 31, 1997, 1998 and 1999

  Software license revenue. Our total revenue increased from $1.1 million to
$7.7 million to $19.1 million in 1997, 1998 and 1999, representing growth of
595% and 148%. Our software license revenue increased from $748,000 to $4.0
million to $8.2 million in 1997, 1998 and 1999, representing growth of 431% and
106%. The increases were due to increased acceptance of our expanded product
offering in the marketplace resulting from a greater number of licenses sold
and a larger average transaction size. Total licenses sold increased from six
in 1997 to 26 in 1998 to 41 in 1999. License revenue transactions increased
from an average of $125,000 in 1997 to $153,000 in 1998 to $200,000 in 1999.


  Service, maintenance and other revenue. Service, maintenance and other
revenue increased from $360,000 to $3.7 million to $10.9 million in 1997, 1998
and 1999, representing growth of 937% and 192%. These increases were due to an
increase in consulting, training and maintenance fees associated with the
increased number of licenses sold and the increased average transaction size
and a larger installed license base. The value of service, maintenance and
other transactions increased from an average of $60,000 in 1997 to $144,000 in
1998 to $266,000 in 1999.

                                       22

  Cost of software license revenue and royalties. Cost of software license
revenue and royalties revenue increased from $36,000 to $438,000 to
$1.6 million in 1997, 1998 and 1999, representing approximately 3%, 6% and 8%
of total revenue. The increase in absolute dollar amount was due to increases
in software license and royalties revenue which increased the related royalty
costs. The increase from 1997 to 1998 in cost of software license and royalties
revenue as a percentage of total revenue related to an increase in royalty fees
for technology licensed by CrossWorlds. The increase from 1998 to 1999 in cost
of software license and royalties revenue as a percentage of total revenue was
related to the amortization of guaranteed minimum royalty payments. We expect
this percentage to decrease in the future as a result of our replacing the
licensed technology with our own internally developed product during the fourth
quarter of 1999.

  Cost of service, maintenance and other revenue. Cost of service, maintenance
and other revenue increased from $1.9 million to $5.4 million to $10.1 million
in 1997, 1998 and 1999, representing 168%, 70% and 53% of total revenue. The
increase in cost of service, maintenance and other revenue in absolute dollars
across all periods was due to an increase in personnel costs. Cost of service,
maintenance and other revenue as a percentage of total revenue declined in 1998
and 1999 because of greater usage of our consulting staff to generate revenue.
We expect our cost of service, maintenance and other revenue to continue to
increase in absolute dollars in future periods.

  Research and development expenses. Research and development expenses
increased from $4.1 million to $11.7 million to $14.2 million in 1997, 1998 and
1999. The increase in each of these periods was due to an increase in personnel
dedicated to new product initiatives. Research and development expenses
represented 368%, 152% and 75% of total revenue in 1997, 1998 and 1999. The
decrease as a percentage of total revenue was the result of growth in our total
revenue. We expect our research and development expenses to continue to
increase in absolute dollars in future periods.

  Sales and marketing expenses. Sales and marketing expenses increased from
$7.0 million to $23.1 million from 1997 to 1998 and decreased to $21.8 million
in 1999. Sales and marketing personnel costs increased from $2.2 million in
1997 to $6.9 million in 1998, travel and entertainment costs increased from
$875,000 to $3.2 million, overhead costs increased from $1.0 million to $4.2
million and commissions and bonuses increased from $261,000 in 1997 to $3.3
million in 1998. In 1998, we also made significant expenditures on advertising
and marketing programs, which increased from $2.3 million in 1997 to
$4.3 million in 1998. We also invested in foreign operations in Australia and
Asia in 1998, resulting in $734,000 in expenses. The decrease from 1998 to 1999
reflects significant reductions in expenditures on advertising from $4.3
million to $2.3 million, and the closure of foreign operations in Australia and
Asia offset by increases in commissions and bonus expenses from $3.3 million in
1998 to $4.8 million in 1999. Sales and marketing expenses represented 628%,
300% and 114% of our total revenue in 1997, 1998 and 1999. The decrease as a
percentage of total revenue was the result of growth in total revenue during
both periods and reduced spending from 1998 to 1999. We expect our sales and
marketing expenses to continue to increase in absolute dollars in future
periods.

  General and administrative expenses. General and administrative expenses
increased from $2.3 million to $4.1 million to $6.1 million in 1997, 1998 and
1999, representing 207%, 53% and 32% of our total revenue in 1997, 1998 and
1999. Expenses increased in each period due to increased staffing necessary to
manage and support our growth. The decrease as a percentage of our total
revenue was due to the growth in our total revenue.

  Other income (expense). Other income increased from $166,000 in 1997 to
$479,000 in 1998, despite the lower year end cash balance in 1998. This
increase was due to our completion of a $23.0 million financing at the end of
1997, resulting in a higher average cash balance in 1998 than in 1997. In 1999,
other expense was $1.9 million. This expense in 1999 was due to the $1.0
million write-off of a prepaid royalty asset and approximately $1.0 million in
interest payments on outstanding debt.

                                       23

  Amortization of deferred stock-based compensation. During 1998 and 1999, we
recorded total deferred stock-based compensation of $8.6 million and $225,000
for stock option grants. We are amortizing these amounts over the vesting
periods of the applicable options, resulting in amortization expense of
$4.8 million and $1.5 million in 1998 and 1999.

  Provision for income taxes. We incurred net operating losses in 1997, 1998
and 1999 and consequently paid no federal, state and foreign income taxes in
those years.

  As of December 31, 1999, we had federal and state net operating loss
carryforwards of approximately $85.1 million and $70.2 million. We also had
federal and state research and development tax credit carryforwards of
approximately $1.2 million and $852,000. Our federal net operating loss
carryforwards will expire at various dates beginning 2011 through 2019 if not
utilized and our state net operating loss carryforward expires beginning in the
year 2004.

  As of December 31, 1998 and 1999, we had deferred tax assets of approximately
$23.0 million and $39.7 million. Our net deferred tax assets have been fully
offset by a valuation allowance. Our net valuation allowance increased by $16.2
million and $16.8 million during 1998 and 1999. Deferred tax assets relate
primarily to net operating loss carryforwards, and capitalized research and
development costs.

  Overall trends. The trends discussed previously in the annual comparisons of
operating results from 1997 through 1999, generally apply to the comparison of
results of operations for our eight most recent quarters ended December 31,
1999.

  Revenue mix. Our software license and service revenue mix fluctuated
significantly at various times during the last eight quarters because the
service components of our sales contracts fluctuated based on the customization
and installation needs of our customers.

  In the quarter ended September 30, 1998, software license revenue was lower
as a percentage of total revenue relative to the other seven quarters ended
December 31, 1999 because fewer sales were closed in the prior quarter and
three significant projects were completed in the prior quarter. We also started
and completed three limited implementation projects designed to allow customers
to evaluate our software, which resulted in a lower percentage of software
license revenue during the period. During the quarter ended June 30, 1998, 5
sales closed as compared to 8 sales closing in the immediately preceding
quarter ended March 31, 1998. Services, maintenance and other revenue increased
significantly from the quarter ended December 31, 1998 to the quarter ended
March 31, 1999 because of the implementation of two significant projects.

  Cost of software license and royalties revenue. During the quarter ended
December 31, 1998, cost of software license and royalties revenue increased as
a percentage of total revenue due to an increase in royalty fees paid by
CrossWorlds for third party technology licenses. The increase for the two
quarters ended December 31, 1999 in cost of software license and royalties
revenue as a percentage of total revenue related to the amortization of
$500,000 during each of the two quarters for guaranteed minimum royalty
payments for technology licensed by CrossWorlds. We expect this percentage to
decrease in the future as a result of our replacing the licensed technology
with our own internally developed product during the fourth quarter of 1999. In
anticipation of increased customer demand which did not materialize until later
periods, we expanded our professional services

                                       26
<PAGE>


organization during the quarter ended September 30, 1998, resulting in
increased services costs as a percentage of total revenue during that quarter.

  Research and development expenses. Research and development expenses
increased during the quarter ended June 30, 1998 due to increased staffing as
we accelerated our efforts to expand our product lines.

  Sales and marketing expenses.  Sales and marketing expenses increased during
the quarter ended June 30, 1998 as a result of 1) increased advertising, 2)
increased personnel costs and 3) expanded business development efforts as we
established our presence in the marketplace and built strategic partnerships.
Advertising costs during the quarter ended June 30, 1998 increased from
$690,000 during the quarter ended March 31, 1998 to $1.9 million, salary and
wage expense increased from $1.0 million to $1.9 million and expanded business
development efforts increased from $430,000 to $1.0 million.

  Sales and marketing expenses decreased during the quarter ended March 31,
1999 as the result of: 1) our reorganization, 2) the reduction in the size of
our marketing organization, 3) our election not to pursue advertising campaigns
similar to those we pursued in 1998, 4) a reduction in our travel expenses and
5) our strategic decisions in December 1998 to cease our Asian and Australian
operations. From the quarter ended December 31, 1998 to the quarter ended March
31, 1999, salary and wage related expenses decreased from $3.7 million to $2.4
million, advertising expenses decreased from $800,000 to $460,000, travel
expenses decreased from $1.2 million to $600,000 and Asian and Australia
related expenses decreased from $230,000 to $25,000.

  Sales and marketing expenses increased during the quarter ended December 31,
1999 due to increased commissions expense payable to sales and business
development personnel. Commission expense increases are generally not
comparable to revenue increases because we typically recognize revenues on a
percentage-of-completion basis while commissions are earned and expensed in the
quarter in which the sale is made.

  General and administrative expenses. General and administrative expenses
increased during the quarter ended December 31, 1999 as a result of expenses
related to our chief executive officer, and costs incurred employing him,
totalling $1.3 million.

  Total operating expenses. Total operating expenses increased during the
quarter ended June 30, 1999 from the prior quarter as we increased our
investment in research and development, expanded our direct sales force, and
built our finance infrastructure to support our growth. Total operating
expenses increased during the quarter ended December 31, 1999 from the prior
quarter as a result of the increase in sales commission expense and expenses
incurred employing our chief executive officer. Sales commission expense
increased from $970,000 during the quarter ended September 30, 1999 to $2.2
million during the quarter ended December 31, 1999 and expenses related to our
chief executive officer increased from $200,000 to $1.5 million during the same
period offset by a reduction in the amortization of deferred stock-based
compensation from $823,000 to ($283,000).

  Other expenses. Other expense increased during the quarter ended December 31,
1999 due to the write-off of a prepaid royalty asset. Our quarterly results
have varied widely in the past, and we expect that they may continue to
fluctuate in the future.

  Seasonality. We have experienced, and expect to continue to experience,
seasonality in software and service orders. In recent years, there has been a
relatively greater demand for our products in the fourth quarter than in each
of the first three quarters of the year, particularly the first quarter. As a
result, we have historically experienced relatively higher sales in the fourth
quarter than in other quarters. We believe that these fluctuations are caused,
in part, by customer buying patterns often influenced by year end budgetary
pressures and the efforts of our direct sales force to meet or exceed year-end
sales quotas. European sales may also tend to be lower during the summer months
than during other periods. We expect that seasonal trends will continue.

                                       27
<PAGE>


  Revenue recognition. We recognize software license revenue over the project
implementation cycle, which is typically from three to nine months. As a
result, we expect that software license revenue will only be partially affected
by seasonal trends.

                        Liquidity and Capital Resources

  Funding to date. We have funded our operations through December 31, 1999
through private sales of preferred equity securities, totaling $85.7 million
and commercial bank loans and equipment leases. As of December 31, 1999, we had
$12.5 million in cash and cash equivalents.

  Sources and uses of cash. Our operating activities resulted in net cash
outflows of $11.4 million, $32.0 million and $28.8 million in 1997, 1998 and
1999. The sources of cash were: 1) increases in accumulated liabilities, 2)
increases in accrued compensation and related expenses, and 3) increases in
deferred revenue in 1997, 1998 and 1999. Uses of cash in operating activities
were due to net operating losses and increases in accounts receivable for 1997,
1998 and 1999.

  Investing. Investing activities used cash of $1.8 million in 1997, $3.7
million in 1998 and $785,000 in 1999 because of purchases of capital equipment.
In April 1999, we began leasing equipment through a $1.5 million master lease
agreement with a lender.

  Financing. Financing activities provided:

  .  $36.7 million in 1997 through the issuance of preferred stock and
     proceeds from an equipment loan;

  .  $16.3 million in 1998, through the issuance of preferred stock, proceeds
     from an equipment loan and proceeds from the issuance of convertible
     subordinated notes and proceeds from a revolving line of credit; and

  .  $36.6 million in 1999, from the issuance of preferred stock and the
     issuance of a subordinated loan.

  Credit facilities. As of December 31, 1999, our principal commitments
consisted of:

  .  obligations to Silicon Valley Bank under:

    .  a revolving line of credit,

    .  equipment facility loans, and

    .  an irrevocable letter of credit, and

  .  obligations to Comdisco under:

    .  the master lease agreement and

    .  a subordinated loan and security agreement.

As of December 31, 1999, we had $6.5 million in outstanding borrowings which
are payable through 2002. Our revolving line of credit provides for borrowing
of up to $10.0 million based on 60% of eligible accounts receivable. Borrowings
under this line of credit accrue interest that is payable monthly at 0.10%
above prime rate. As of December 31, 1999, we had no borrowings against this
line of credit. Borrowings are secured by all of our assets. We have agreements
that require us to comply with financial covenants. These covenants are that we
maintain a 1.5 to 1.0 quick ratio, a $3.3 million tangible net worth and a 1.5
to 1.0 liquidity coverage ratio. As of December 31, 1999, we were in compliance
with each of these covenants.

  Deferred revenue. Deferred revenue consists of the unrecognized portion of
license and maintenance sales contracts. Our deferred revenue balance or
changes in that balance may not be indicative of our total backlog or changes
in the ordering patterns of our customers. Capital expenditures were for
computer workstations used for product development, product demonstrations and
customer support.

                                       28
<PAGE>


  Future funding requirements. We believe that the net proceeds from this
offering, together with our current cash balances and the cash flows generated
by operations and tax refunds, if any, will be sufficient to satisfy our
anticipated cash needs for working capital and capital expenditures for at
least the next twelve months. After that we may require additional funds to
support our working capital requirements, or for other purposes. We may also
seek to raise additional funds through public or private equity financings or
from other sources. We may not be able to obtain adequate or favorable
financing at that time. Any financing we obtain may dilute your ownership
interests.

  A portion of our cash may be used to acquire or invest in complementary
businesses or products, or to obtain the right to use complementary
technologies. We have no current plans, agreements or commitments of this
nature, and we are not currently engaged in any negotiations involving such a
transaction.

Qualitative and Quantitative Disclosures about Market Risk

  Because we market our products in the United States and in foreign countries,
our financial results could be affected by factors including changes in foreign
currency exchange rates or weak economic conditions in foreign markets. Our
interest income is sensitive to changes in the general level of U.S. interest
rates, particularly because the majority of our investments are in short-term
instruments. Due to the nature of our short-term investments, we believe that
there is no material interest rate risk exposure. Consequently, no quantitative
tabular disclosures are required.

Recent Accounting Pronouncements

  In December 1998, the governing body of the American Institute of Certified
Public Accountants, issued SOP 98-9, Software Revenue Recognition, with Respect
to Certain Arrangements. SOP 98-9 requires that revenue be recognized using the
residual method in a multiple-element arrangement when fair value does not
exist for one or more of the undelivered elements in the arrangement. Under the
residual method, the total fair value of the undelivered elements is deferred
and subsequently recognized in compliance with SOP 97-2. We adopted SOP 98-9 on
January 1, 2000, and do not expect this adoption to have a material effect on
our consolidated financial position or results of operations.

Industry Background

 The Need for Collaborative Business Strategies

  In recent years, many large companies have faced an increasingly competitive
business environment. This competitive environment has been further complicated
by changes in government regulation, mergers and acquisitions, and the
increasing adoption of e-business strategies. In response to this changing
environment, many companies are modifying their operations to increase
efficiency and become more responsive to customer and market demands.

  In pursuit of these goals, many companies are implementing collaborative
business strategies that improve coordination and communication among multiple
business functions, divisions and trading partners. Examples of these
strategies include:

  . using Internet-based marketplaces and trading exchanges;

  . collaborative supply and demand planning among trading partners;

  . outsourcing customer service and manufacturing activities to third
    parties; and

  . inventory management across multiple company divisions and distribution
    channels.

  Efforts to implement the above strategies, however, have been constrained by
various information technology and business issues, including:

  . companies have traditionally been managed on a functional basis with
    minimal coordination between functions including procurement,
    manufacturing, sales, logistics and administration;

  . companies have adopted disparate packaged and custom enterprise
    applications to automate each business function, including:

    (a) enterprise resource planning applications from vendors including SAP
        and Oracle,

    (b) customer relationship management applications from vendors including
        Siebel and Clarify,

    (c) supply chain management applications from vendors including i2
        Technologies, Manugistics Group, Inc. and Numetrix, a J.D. Edwards
        Company,

    (d) e-business applications from vendors including SAP, Ariba, Inc. and
        BroadVision, Inc., and

    (e) industry-specific applications from vendors including Portal and
        MetaSolv;

                                       30
<PAGE>

  . business processes typically span multiple functions and applications,
    requiring a significant level of integration within the enterprise;

  . extending internal and outsourced business processes outside the
    enterprise requires integration and coordination among customers' and
    suppliers' applications; and

  . technological incompatibilities and functional differences among
    disparate applications make it difficult for these systems to communicate
    in real time and to be integrated over the Internet.

  For example, a seemingly simple task such as receiving and fulfilling a
customer's order over the Internet may require interaction among the e-
business, order management, manufacturing, logistics and accounting systems
within one company, and the customer service, manufacturing and accounting
systems of multiple trading partners, each using its own enterprise
applications. The total dollar value of these business-to-business transactions
over the Internet is expected to grow to $1.3 trillion by 2003, according to
Forrester Research.

  As a result of this complexity, most large organizations face significant
integration challenges. To address these challenges, companies need a flexible
e-business infrastructure that automates internal and Internet-based business
processes while utilizing existing investments in enterprise applications. The
Yankee Group estimates that approximately 35% to 40% of total corporate
information technology spending is now consumed by systems integration costs.
This spending includes the cost of integration both within the enterprise and
among trading partners over the Internet.

 Current Business Integration Market

  Business integration solutions have traditionally been provided by numerous
parties, including:

  . systems integrators;

  . information technology departments within companies; and

  . software vendors.

According to International Data Corporation Research, the worldwide systems
integration services market is expected to grow from $41.0 billion in 1996 to
$90.0 billion by 2003.

  The market for e-business software, according to Forrester Research, is
expected to grow from $121.0 million in 1997 to $3.8 billion in 2002. The
related market for data integration tools and enterprise application
integration software, according to the Yankee Group, is expected to grow from
$1.6 billion in 1998 to $5.0 billion in 2001. The Yankee Group defines
enterprise application integration software as products that integrate business
applications both within an enterprise and among trading partners.

  To date, the business integration software market has been comprised of four
segments:

  . Messaging-Oriented Middleware is the underlying software that manages the
    movement of simple messages between applications. These products offer
    limited support for business logic that defines how, when and in what
    form data is transmitted between applications. Companies offering
    products in this segment include IBM, TIBCO and BEA.

  . Enterprise Application Integration Tools allow companies to build
    customized links between pairs of applications, known in the industry as
    point-to-point interfaces. These tools enable users to convert data from
    one application into a format that is able to be used by another
    application. Companies offering products in this segment include Active
    Software Inc., New Era of Networks Inc. and Mercator Software, formerly
    TSI Software International.

  . Electronic Data Interchange Software uses industry-specific data formats
    to enable point-to-point electronic links for the purpose of transmitting
    business documents. Companies offering products in this segment include
    Sterling Commerce and Harbinger.

                                       31
<PAGE>


  . XML Tools enable companies to build integration solutions based on the
    exchange of XML-formatted documents. These solutions typically do not
    address the integration requirements of applications within the
    enterprise. Companies offering products in this segment include
    OnDisplay, Inc. and webMethods, Inc.

 Shortcomings of Common Business Integration Approaches

  While the adoption of these products has driven substantial growth in the
business integration software market, we believe these products fail to provide
a complete business integration solution for a number of reasons:

  . Inability to Support e-Business. Many current business integration
    products lack support for standard Internet data formats and
    communication protocols. Furthermore, most solutions are not able to
    support complex, Internet-based processes between trading partners.

  . Lack of Business Process Support. Many tools-based or electronic data
    interchange solutions support the transmission of data or business
    documents rather than automating business processes between applications
    and enterprises. Many products do not provide pre-built support for the
    most common business process integration requirements.

  . Lack of Pre-built Application Connectivity. Many business integration
    solutions do not provide pre-built connectivity to the market's leading
    e-business and enterprise applications. Without this pre-built
    connectivity, companies may find it difficult to pursue e-business
    strategies using their existing information technology infrastructure.

  . Architectural Inflexibility. Most custom built interfaces cannot be
    easily applied to similar situations and require significant
    modifications or full-scale reprogramming when adding applications. Many
    business integration products are either based on out-dated technologies
    or do not provide an architecture that combines all required integration
    technologies into a unified product.

 New Approaches for Business Integration

  We believe that a large opportunity exists for software vendors to address
these limitations by delivering solutions that:

  . provide an e-business infrastructure for the integration and automation
    of business processes both within the enterprise and among customers and
    suppliers over the Internet;

  . provide an open platform that supports high volumes of business
    transactions and meets the system management requirements of large
    companies;

  . utilize the functionality of leading enterprise application packages;

  . reduce changes to existing information technology environments; and

  . operate in a variety of technical environments including those comprised
    of custom and packaged applications, various operating systems and the
    Internet.

  A comprehensive business integration solution with the above features would
improve operating efficiencies, enable organizations to adapt to changes in
business and information technology requirements and allow companies to realize
the benefits of e-business.

The CrossWorlds Solution

  Our e-business infrastructure software integrates and automates business
operations within companies and among their customers and suppliers over the
Internet. Our products are based on a modular architecture that meets the
requirements of large enterprises, and combines standard Internet technologies

                                       32
<PAGE>


with proprietary innovations. We offer a set of tools that customers can use to
build e-business integration solutions, and extend and customize our pre-built
components. Our pre-built components consist of connectivity solutions for
leading applications and business process modules for integrating common e-
business and enterprise processes.

  Our products are characterized by five elements:

 Flexible e-Business Infrastructure

  We believe our products provide a foundation for enabling e-business
transactions between companies and their trading partners. We support a number
of the leading packaged e-business applications and development environments.
Our architecture also supports multiple e-business and Internet data and
communication standards. When combined with our application integration and
business process automation products, customers can rapidly deploy e-business
solutions that take advantage of their existing information technology
infrastructure.

 Real-time Business Process Automation

  We believe our integration solutions allow customers to accelerate their
e-business initiatives by integrating disparate enterprise applications and
automating their underlying business processes. We believe our solution reduces
process redundancies and data inconsistencies between applications. We offer a
process modeling toolset for building custom business process integration
solutions and pre-built business process integration modules that utilize our
knowledge of industry specific business practices.

 Extensive Packaged Application Integration

  We offer pre-built connectivity products for many of the leading packaged e-
business and enterprise applications. These connectivity products use and
complement the standard interfaces provided by each application vendor. Where
required, we support multiple versions of applications to accommodate
functional and technological changes in their interfaces. This allows customers
to migrate between existing and new application releases with minimal changes
to their integration solution, reducing their long term cost of integration.

 Extensive Custom Application Integration

  We offer a suite of tools that enables customers to extend their integration
solutions to include custom applications. Our tools automate common integration
development tasks including transforming data among different formats and
establishing communications between applications and the CrossWorlds
environment. To accelerate development efforts, we also provide pre-built
connectivity to many common technology environments.

 Scalable Integration Architecture

  Our Java-based architecture supports relevant Internet and technology
standards and can be extended to support new standards as they emerge. This
architecture has been designed to allow customers to adapt to changes in
business and information technology environments, including the addition of new
applications or trading partners and the processing of increasingly large
volumes of information.

Strategy

  Our objective is to establish and maintain a leadership position in the e-
business infrastructure software market. To this end, our strategy includes
these elements:

 Provide Comprehensive e-Business Solutions

  As enterprises increasingly conduct business over the Internet, they will
face a growing number of integration challenges. Over the next twelve months,
we intend to enhance our current e-business product

                                       33
<PAGE>


offering by developing Internet-based business process integration modules and
pre-building connectivity solutions for additional e-business applications
including those used for Internet-based procurement and order management. We
also intend to enhance our architecture by providing support for additional
security and Internet standards as they emerge.

 Expand Business Process Automation and Application Integration Solutions

  We believe that the breadth and depth of our business process automation and
application integration solutions are a primary competitive differentiator in
our target markets. Within a single architecture, our solution addresses a
broad range of integration requirements faced by global enterprises. Over the
next two years we plan to build connectivity to additional packaged
applications and technology environments. We will expand our set of pre-built
business process integration modules to support additional customer
requirements.

 Maintain and Extend Technology Leadership

  Our Java-based, open architecture uses industry-leading messaging middleware
and proprietary innovations, providing an extensible, high-performance e-
business infrastructure. As new technologies evolve, we intend to continue to
improve this technology platform to ensure that our solutions meet the
demanding requirements of large enterprises. We have been granted a patent on
key elements of our technology and have additional patents pending on other
portions of our architecture.

  We believe that sales to global companies in selected industries including
technology, industrial manufacturing, process manufacturing and
telecommunications represent our greatest immediate revenue opportunities. Many
companies in these industries have made significant investments in packaged and
custom applications and are pursuing strategies that require the integration of
these applications both internally and with trading partners over the Internet.
Over the next two years we intend to expand our offerings in these markets and
to target additional industries in the future where our solution can provide
significant strategic benefit.

 Promote Broad Acceptance of the CrossWorlds Platform

  We are planning initiatives to promote broader acceptance of the CrossWorlds
platform. One element of this plan is the CrossWorlds Exchange, an online,
subscription-based resource containing a repository of integration components
based on our open architecture. The CrossWorlds Exchange will also provide
access to methodologies and templates to facilitate product development and
implementation by customers, systems integration and other third parties. The
CrossWorlds Exchange will be implemented in phases over the next six months.
Another element of this plan is to work with partners to expand distribution of
our products into additional industries.

 Expand Strategic Partnerships

  We intend to continue to develop and extend our strategic partnerships to
promote adoption of our e-business infrastructure solutions. We believe that
these strategic partnerships provide us with a competitive advantage. Our
partnerships with enterprise application and other technology vendors and
systems integrators provide sales and marketing support and access to required
technology and expertise. Currently, our most significant strategic partners
are IBM, SAP and a number of global systems integrators. Over the next twelve
to twenty-four months we expect our systems integrator partners will
increasingly provide the resources needed to implement our products.

Business Process Integration Products

  Our business process integration solution is comprised of pre-built modules
and development tools that enable business process integration within the
enterprise and among trading partners over the Internet. Our solution allows
customers to:

  . extend the functionality of individual applications, which enables
    additional e-business capabilities;

  . reconcile differences and redundancies in the information managed by
    disparate applications; and

  . provide access to information not usually available to the user of a
    single application.

  The foundation for our business process integration solution is our common
object model. All business processes within our system operate using a data
model that is designed to be independent of the way any specific application
represents its data. This common object model is a superset of the models
employed by the most widely deployed packaged enterprise applications. We
believe that the use of a common object model for business process integration
reduces the maintenance burden of the integration.

                                       35
<PAGE>

 Business Process Integration Toolset

  Business process integration modules are created and extended using the
CrossWorlds Designer suite of tools. The CrossWorlds Process Designer is a
standards-based tool for creating CrossWorlds common objects, designing
business process flows and automatically generating the underlying Java
programming code to operate on the CrossWorlds InterChange Server. To simplify
development and customization, process components are presented to the user
visually, and are defined and configured through the CrossWorlds Process
Designer's graphical user interface.

 Pre-Built Business Process Integration Modules

  In addition to creating their own business process integration modules with
our tools, our customers can use our pre-built integration modules to integrate
many of the common business processes required for e-business and other
enterprise business functions. These pre-built components utilize our common
object model, allowing multiple processes to be combined into solutions that
address complex requirements. Our pre-built process integration modules are
grouped into three product lines that are detailed in these three tables.

  CrossWorlds eBusiness. Our eBusiness product line includes business process
integration modules for integrating e-business applications and enabling
companies to collaborate with their trading partners over the Internet.
CrossWorlds eBusiness is designed to allow enterprises to implement e-business
solutions that take advantage of their existing information technology
investments.

Infrastructure Products

  Our process automation and application integration solutions are deployed on
the CrossWorlds InterChange Server, a Java-based, software product that scales
to meet the requirements of global organizations and trading networks with
large volumes of transactions.

  We believe that CrossWorlds' infrastructure products exhibit the key
characteristics of software solutions used by large global organizations:

  Technology Infrastructure. Our InterChange Server utilizes a combination of
proprietary technologies and industry-standard messaging middleware from IBM.
The CrossWorlds InterChange Server is Java-based and modular allowing us to
support the most widely-accepted operating systems and technology standards. We
have been granted a patent on key elements of our architecture.

  e-Business Foundation. Our open platform supports a variety of Internet
standards, including Extensible Markup Language, or XML, RosettaNet, Hypertext
Markup Language, or HTML, Hypertext Transfer Protocol, or HTTP, File Transfer
Protocol, or ftp, and Electronic Data Interchange, or EDI. The CrossWorlds
InterChange Server:

  .  provides interfaces for multiple data formats;

  .  supports communications over multiple protocols; and

  .  allows us to support new and emerging e-business standards. Integrated
     security ensures the integrity and confidentiality of exchanges between
     trading partners.

  Scalability. Our e-business infrastructure is designed to meet the growing
integration needs of organizations with multiple packaged and custom
applications. The CrossWorlds InterChange Server is capable of executing
multiple business processes simultaneously in a distributed environment. Our
modular architecture gives customers flexibility in deploying our solution, and
allows them to improve performance of individual components to enable the
overall solution to grow with their needs.

  Manageability. Our System Manager tool is used to manage the CrossWorlds
environment. The CrossWorlds System Manager is a visual tool and is tightly
integrated with the CrossWorlds InterChange Server, enabling users to monitor
and control the execution of our business process integration modules and
connectivity solutions from a single user interface.

  Adaptability. Our architecture allows business process modules and connectors
to be implemented independent of each other. This separation enables our
customers to mix and match business process modules and connectors, which makes
the integration solution more adaptable to changing business requirements.

Customer Case Studies

  These case studies are intended to show the uses of CrossWorlds products in
real world applications. These case studies are not intended to be an
endorsement of CrossWorlds or its products.

  Customer: Neoforma.com, healthcare e-business network provider

  Problem: Neoforma.com is building an online healthcare marketplace over the
  Internet that will serve as a global network to bring together healthcare
  providers and medical suppliers to exchange information and buy and sell
  medical products, supplies and equipment. To accomplish this, Neoforma.com
  is integrating mySAP.com Marketplace with its internal applications and
  plans to integrate its online marketplace with the exchange participants'
  order management and purchasing applications.

  Solution: Neoforma.com is implementing CrossWorlds as the core integration
  solution to provide healthcare providers and suppliers a conduit to connect
  with the mySAP.com Marketplace. CrossWorlds eBusiness will be used to
  automate the exchange by recording order information from healthcare
  providers and product information from medical suppliers and formatting it
  for the mySAP.com Marketplace. CrossWorlds will standardize and maintain
  the core business logic and master data definitions involved in the
  transactions including item, master customer, master vendor, master orders,
  account status and inventory level. The purpose of this standardization is
  to ensure consistent, accurate exchange of information and to facilitate
  the buying and selling of medical products, supplies and equipment.
  Neoforma.com will also use CrossWorlds to integrate mySAP.com and
  Neoforma.com's internal ERP system.

  Customer: Delphi Automotive, automotive technologies, systems and
  components

  Problem: Delphi needed a standardized integration solution that could tie
  together numerous packaged and custom applications to support the company's
  complex business processes. These applications operate within multiple
  business units, and Delphi wanted a solution that would improve the
  efficiency of data sharing across the company. Delphi currently has a large
  SAP ERP implementation along with a myriad of custom applications that
  manage production, purchasing and fulfillment.

  Solution: Delphi is implementing CrossWorlds to integrate the company's
  complex application environment across the enterprise. From CrossWorlds,
  Delphi purchased the CrossWorlds SAP Connector, multiple CrossWorlds
  Technical Connectors, the CrossWorlds InterChange Server, the CrossWorlds
  Connector Development Kit and multiple pre-built CrossWorlds Business
  Process Integration Modules to integrate key information and automate the
  processes across business units.

  Customer: U S WEST, telecommunications service provider

  Problem: U S WEST !NTERPRISE, U S WEST's data networking and new product
  development division, needed to integrate the common business processes for
  customer relationship management, order history and service contracts
  across three customer service and back-office applications.

  Solution: U S WEST implemented CrossWorlds Customer Interaction solution to
  enable a bi-directional flow of information between these applications,
  ensuring a consistent and accurate picture of its customers, products and
  contracts. As a part of U S WEST's new systems architecture, CrossWorlds'
  solution helped U S WEST achieve a five-fold increase in the number of
  quotes for contracts and renewals processed within the first month of
  implementation. U S WEST estimates they have achieved a 35% cost savings in
  this first phase of the CrossWorlds implementation, simply because of the
  ease of making changes to customer contracts.

  CrossWorlds provides connectivity solutions for products from other vendors
with whom we have no formal relationship including those provided by Kenan,

Sales

  We sell our software primarily through our direct sales organization. As of
December 31, 1999 our direct sales force consisted of 24 sales professionals
located in offices in North America and Europe. We have domestic offices
located in California, Illinois, Maryland, Massachusetts, Michigan, Minnesota,
New Jersey, New York, North Carolina and Texas. Our European headquarters is
based in Munich, Germany and we have also established subsidiaries and local
offices in France and the United Kingdom. Technical sales support is provided
by 15 pre-sales representatives located in the corporate and field offices. The
field sales force is complemented by four telebusiness staff based in our U. S.
headquarters and two telebusiness and marketing staff based in our Munich
office.

  We deploy sales teams consisting of both sales and technical sales support
professionals to create industry-specific proposals, presentations and
demonstrations that address the specific requirements of the customer. Our
typical customer is a Fortune 1000 company in the technology, industrial
manufacturing, process manufacturing or telecommunications industry. The
initial sale cycle varies significantly from customer to customer. To date, it
has ranged from two to nine months.

                                       44
<PAGE>

Marketing

  Our marketing efforts are directed at establishing a market leadership
position for our software in the e-business infrastructure software market. Our
marketing programs are focused on creating awareness and generating interest in
our solution to increase sales and are targeted at information technology
managers, chief information officers, chief financial officers and other senior
executives within global Fortune 1000 companies. Our marketing plan includes
these elements:

  Brand Awareness and Public Relations. We believe that our brand identity has
improved our sales effectiveness by providing access to executives at target
accounts and contributed to our ability to attract partners. To build brand
awareness, we engage in a range of public relations activities including
industry analyst relations, press releases, media relations and media tours.

  Lead Generation. We have developed lead-generation programs, including direct
mail campaigns, seminar series and audioseminars, targeted at specific
audiences and account profiles. We participate in selected trade shows and
partner user group events with the goal of identifying prospective customers.
These efforts are complemented by our own internal telebusiness organization,
which provides support for lead-generation activities.

  Joint Marketing. With our application, technology and systems integrators
partners, we have planned and executed a variety of marketing programs
including trade shows and user groups, joint speaking opportunities, seminar
tours, public relations and advertising campaigns. To date, we have executed
joint marketing activities with Clarify, Compaq, Deloitte Consulting, Ernst &
Young, IBM, MetaSolv, Oracle, PeopleSoft, Portal, PricewaterhouseCoopers, SAP
and Siebel.

Customer Support, Implementation and Training

 Customer Support

  We have implemented a customer support strategy to promote successful
implementation and customer satisfaction. This multi-tiered approach includes
on-line support through the Internet, toll-free telephone technical support and
on-site support from our client services team when required. Our Internet
service programs provide links to selected CrossWorlds systems, including
product documentation, technical notes and a frequently asked questions
database. Customers can directly check the status of their technical support
requests over the Internet. A toll-free phone number also provides customers
with access to technical service professionals on a 24-hour a day, 7-day a week
basis. Our staff also provides on-site support to resolve more complex issues,
typically on a fee-for-service basis.

  We measure the satisfaction level of each customer annually using a customer
satisfaction research firm to help us identify, analyze and solve customer
service problems.

 Client Services

  To install and configure our products, we maintain an internal client
services implementation team with expertise at installing and configuring our
products at client sites. While most customer implementations to date have been
performed by our internal staff, our long term implementation strategy is to
support the efforts of our third-party systems integrator partners with a small
number of CrossWorlds' client services resources on each client project. We
believe the presence of our client service staff has helped maintain the
consistency and quality of our product implementation.

 Training

  We offer a range of training courses in the installation, configuration,
customization and administration of our products. Typically, these courses are
attended by the relevant members of a customer's information

                                       45
<PAGE>


technology team. We also train third-party implementation personnel on the
installation, customization and configuration of our products. Training is
available at our training facility in Burlingame, California and at various
locations around the world through a third-party training provider. Customers
and implementation partners can arrange for dedicated classes to be provided at
their own facilities.

Research and Development

  We have made substantial investments in research and development. When we
think it makes sense, we license technology from leading third-party providers
and engage in cooperative development with systems integrator partners to
reduce our own research and development expenditures. Through December 31,
1999, we have invested approximately $30.8 million in research and development.

  We believe that high levels of research and development spending continue to
be vital to our success because of:

  . the complexity of developing a comprehensive integration solution for e-
    business and the enterprise;

  . the need to support an increasing number of packaged enterprise
    applications, particularly in the e-business and telecommunications
    markets;

  . the ongoing expansion of functionality in each of our product lines; and

  .  the increasing functional depth of our industry solutions for
     manufacturing and telecommunications.

  We focus our research and development efforts on the development of
collaboration modules and connectivity solutions, the supporting infrastructure
and tools, quality assurance and technical publications that support all facets
of product usage. We are also engaged in the development of advanced
technologies and the evaluation of emerging third-party products that can be
utilized in future releases of our products.

  On December 31, 1999, there were 75 employees in our research and development
organization. Approximately half of these employees are dedicated to developing
collaboration modules and connectivity solutions. The rest of these employees
are focused on infrastructure development, quality assurance, documentation and
technical support.

   We have a technical advisory board. The board is made up of senior
executives from Compaq, McKinsey & Company, Ernst & Young and SAP. The board
provides feedback on existing product plans and guidance for future research
and development activities.

Intellectual Property and Other Proprietary Rights and Limited Protection of
These Rights

 Legal Protections

  We rely on patent, copyright, trademark and trade secret laws and
restrictions on disclosure to protect our intellectual property rights. We have
been granted one patent relating to our architecture. We have four pending U.S.
patent applications relating to the architecture of our products. These
applications may not be approved. Patents we may be issued may not protect our
intellectual property and may be challenged by third parties. Other people may
independently develop similar or competing technology or design around any
patents that may be issued to us. We have three pending U.S. and international
trademark applications.

 Confidentiality and License Agreements

  We enter into confidentiality or license agreements with our employees,
consultants and corporate partners to protect our proprietary information. We
also control access to and distribution of our software, documentation and
other proprietary information. We provide our products to end-users primarily
under non-exclusive license agreements that impose restrictions on customers'
use of the software.

                                       46
<PAGE>


 Limited Protection of Our Rights

  Despite our efforts to protect our proprietary rights, existing laws afford
only limited protection. People may try to copy or reverse engineer aspects of
our products or to obtain and use information that we believe is proprietary.
We may not be able to protect our proprietary rights against unauthorized
copying or use. That kind of misuse of our proprietary rights could hurt our
business. It is hard to monitor unauthorized use of our products, and the steps
we have taken to prevent misappropriation of our technology may not work,
particularly in foreign countries where the laws may not protect our
proprietary rights as fully as in the United States.

 Claims

  The software industry is characterized by the existence of a large number of
patents and frequent litigation based on allegations of patent infringement and
the violation of other intellectual property rights. We attempt to avoid
infringing known proprietary rights of third parties in our product development
efforts. Nevertheless, we expect that we may be subject to legal proceedings
and claims for alleged infringement by us or our licensees of third party
proprietary rights, such as patents, trademarks or copyrights. Any claims
relating to the infringement of third party proprietary rights, even if not
meritorious, could:

  .  result in costly litigation,

  .  divert management's attention and resources, and

  .  require us to enter into royalty or license agreements which are not
     advantageous to us.

  Parties making these claims may be able to obtain an injunction, which could
prevent us from selling our products in the United States and abroad. Any of
these results could harm our business. We may increasingly be subject to
infringement claims as the number of products and competitors in our industry
grow and product functionalities overlap. Furthermore, former employers of our
current and future employees may assert that our employees have improperly
disclosed confidential or proprietary information to us.

Competition

  The market for our products is intensely competitive, and is expected to
become increasingly competitive as current competitors expand their product
offerings and new competitors enter the market. Our current competitors include
a number of companies offering one or more solutions to the application
integration problem, some of which are directly competitive with our products.

 Internal Information Technology Departments

  To date, the majority of the competition we have faced has been from the
internal information technology departments of potential customers that have
developed or may develop in-house integration solutions that may substitute for
those offered by us. We expect that these internal development initiatives will
continue to be a principal source of competition. The competitive factors in
this area require that we produce a product that conforms to the prospective
customer's information technology standards, scales to meet the needs of large
enterprises and costs less than their internal development efforts.

 Systems Integrators

  A second source of competition results from systems integrators and other
information technology service providers that customers engage to build
customized integration solutions across multiple customer applications. The
competitive factors in this area require that we demonstrate to our prospective
customers, systems integrators and other service providers the cost savings,
risk reduction and other advantages of an integration solution based on
commercially-supported software.

                                       47
<PAGE>


 Integration Software Providers

  Our competitors also include a large number of software vendors targeting one
or more segments of the business integration software market through various
technological solutions. Most of the competitors offer components of a complete
solution. Some competitors' solutions are centered on messaging and data
transport technologies, including BEA, Microsoft Corporation, and TIBCO. Other
competitors' solutions are focused on e-business and integration tools. These
competitors include Active Software, Extricity Software, Inc., Mercator
Software, New Era of Networks, OnDisplay, Software Technologies Corporation,
Vitria Technology Inc. and webMethods.

  Many of these 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 we do.
Many competitors have well-established relationships with current and potential
customers. As a result, these competitors may be able to respond more quickly
to new or emerging technologies and changes in customer requirements, or to
devote greater resources to the development, promotion and sale of their
products than we could.

  In addition, 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. It is
possible that new competitors or alliances among competitors may emerge and
rapidly acquire significant market share. Potential competition could emerge
from companies such as Hewlett-Packard, IBM, Microsoft and Oracle. Increased
competition is likely to result in price reductions, reduced gross margins and
loss of market share.

Employees

  As of December 31, 1999, we had a total of 202 employees, 178 were based in
North America, and 24 were based in Europe, principally in the United Kingdom
and Germany. Of the 202 employees, 65 were engaged in sales and marketing, 75
were in product development and customer support, 40 were in implementation
services and 22 were in finance, administration and operations. None of our
employees is represented by a labor union. We have not experienced any work
stoppages and consider our relations with our employees to be good.

Facilities

  Our headquarters are located in approximately 40,000 square feet in
Burlingame, California. The lease on this office space expires in April 2008.
We currently lease other domestic sales and support offices in California,
Colorado, Connecticut, Illinois, Maryland, Massachusetts, Michigan, New Jersey,
New York, North Carolina; and Texas. We also maintain international offices in
leased facilities located in the United Kingdom, France and Germany. The German
office also serves as our European headquarters.

Option Grants

  This table provides summary information on stock options granted to the
officers in the table below during the year ended December 31, 1999.

  The percentage of total options granted to employees is based on an aggregate
of 6,968,975 shares granted by CrossWorlds under the 1997 stock plan and the
1999 executive stock plan during the year ended December 31, 1999. Potential
realizable values are net of exercise price, but before taxes for exercise. The
5% and 10% assumed annual rates of compounded stock price appreciation are set
by the Securities and Exchange Commission. The actual stock price appreciation
over the 10-year term is almost certainly not going to be at the assumed 5% and
10% levels or at any other defined level. No value will be realized from the
option grants unless the market price of the common stock appreciates.

Stock Plans

 1997 Stock Plan.

  Adoption and Initial Reserve. Our board of directors originally adopted and
our stockholders originally approved our 1997 stock plan in January 1997. As of
December 31, 1999, we had reserved a total of 4,992,638 shares for issuance
under the 1997 plan. As of December 31, 1999, options to purchase 753,425
shares of common stock had been exercised, options to purchase a total of
3,845,091 shares at a weighted average exercise price of $5.26 per share were
outstanding and 423,612 shares remained available for future option grants. The
1997 plan will terminate in 2007 if not terminated earlier by our board of
directors.

  Reserved Shares Following this Offering. We amended the 1997 plan to provide
for a total of 3,000,000 shares to be available for grant at the effective time
of this offering, plus an automatic annual increase on the first day of each of
our fiscal years beginning in 2001 and ending in 2005 in an amount equal to the
lesser of:

  .  3,000,000 shares,

  .  5% of our outstanding common stock on the last day of the immediately
     preceding fiscal year, or

  .  a lesser number of shares as our board determines.

  We will submit this amendment to the 1997 plan to our stockholders for
approval before the completion of this offering.

  Purposes of the 1997 Plan. The purposes of the 1997 plan are to attract and
retain the best available personnel to CrossWorlds, to provide additional
incentives to CrossWorlds' employees and consultants, and to promote the
success of CrossWorlds' business.

  Eligible Persons and Types of Options. The 1997 plan provides for granting to
employees, including officers and directors, incentive stock options within the
meaning of Section 422 of the Internal Revenue Code of 1986. The 1997 plan also
provides for granting to employees and consultants, including nonemployee
directors, nonstatutory stock options and stock purchase rights. If an option
holder would have

                                       54
<PAGE>


the right in any calendar year to exercise one or more incentive stock options
for shares having a total fair market value in excess of $100,000, any of these
excess options shall be treated as nonstatutory stock options.

  Administration. The board of directors or a committee of the board, each
known as the administrator, may administer the 1997 plan. The compensation
committee currently administers the plan. The administrator determines the
terms of options and stock purchase rights granted under the 1997 plan,
including: 1) the number of shares subject to the award; 2) the exercise or
purchase price; 3) the term, vesting and exercisability of the award; 4) and
other conditions to which the award is subject. An individual employee may not
receive awards for more than 1,000,000 shares under the 1997 plan in any fiscal
year.

  Exercise Price. The exercise price of all incentive stock options granted
under the 1997 plan must be at least equal to the fair market value of our
common stock on the date of grant. The exercise price of any incentive stock
option granted to a person who owns stock representing more than 10% of the
total combined voting power of all classes of outstanding capital stock, or the
stock of any parent or subsidiary corporation of CrossWorlds, must equal at
least 110% of the fair market value of the common stock on the date of grant.

  Before this offering, the exercise price of all nonstatutory stock options
and stock purchase rights were required to have an exercise or purchase price
of at least 85% of the fair market value of the common stock on the date of
grant. After the date of this offering, the exercise price of nonstatutory
stock options and the purchase price of stock purchase rights will no longer be
subject to these limitations. However, nonstatutory stock options and stock
purchase rights granted to our chief executive officer and our four other most
highly compensated officers will be at least 100% of the fair market value of
the common stock on the date of grant if the award is intended to qualify as
performance based compensation under Section 162(m) of the Internal Revenue
Code. Payment of the exercise price may be made in cash or other consideration
as determined by the administrator.

  Other Option Terms. The administrator determines the term of options, which
may not exceed 10 years, or 5 years in the case of an incentive stock option
granted to an employee who owns stock representing more than 10% of the total
voting power of our stock or a parent or subsidiary's stock. Generally, an
option holder may not transfer an option other than by will or the laws of
descent or distribution and only the option holder may exercise the option
during the lifetime of the option holder. However, the administrator may in its
discretion provide for the limited transferability of nonstatutory stock
options granted under the 1997 plan under specified circumstances.

  The administrator determines when options become exercisable. Options granted
under the 1997 plan generally become exercisable at the rate of 1/8th of the
total number of shares subject to the options six months after the date of
grant, and 1/48th of the total number of shares subject to the options each
month from then on.

  Stock purchased under stock purchase rights granted under the 1997 plan is
generally subject to a repurchase right at the purchaser's original purchase
price. CrossWorlds may exercise this repurchase right upon termination of the
purchaser's employment or consulting relationship with us. This repurchase
right lapses according to the terms of the stock purchase right determined by
the administrator at the time of grant.

  Change of Control. If there is a sale of all or substantially all of the
assets of CrossWorlds, or a merger of CrossWorlds with another corporation,
then the successor corporation may assume each option and stock purchase right
or substitute an equivalent award. If the successor corporation refuses to
assume or substitute for an outstanding award, each award shall become fully
vested and exercisable before the effective date of the transaction.

  If the successor corporation assumes or substitutes outstanding awards, and
an option holder's employment with CrossWorlds is involuntarily terminated for
reasons other than cause, as defined below,

                                       55
<PAGE>


within one year following a merger or sale of assets, the option holder will
receive limited accelerated vesting. The accelerated vesting is limited as
described in the 1997 plan. The option holder's outstanding awards shall become
immediately vested and exercisable in an amount equal to 12 months of further
vesting of each award at the rate specified in the applicable stock option or
stock purchase agreement. Outstanding options will adjust if there is a stock
split, stock dividend or other similar change in capital structure.

  Cause shall mean:

  .  gross negligence or willful misconduct in the performance of an
     employee's duties to CrossWorlds;

  .  repeated unexplained or unjustified absence;

  .  a material and willful violation of any federal or state law;

  .  refusal or failure to act in accordance with any specific direction or
     order of, or contractual obligation with, CrossWorlds;

  .  commission of any act of fraud with respect to CrossWorlds; or

  .  conviction of or plea of no contest to a felony or a crime involving
     moral turpitude causing material harm to the standing and reputation of
     CrossWorlds.

  Amendment and Termination. The administrator has the authority to amend or
terminate the 1997 plan as long as this action does not adversely affect any
outstanding option and provided that stockholder approval shall be obtained as
required by applicable law.

 2000 Directors' Stock Option Plan.

  Adoption and Initial Reserve. The board of directors adopted the 2000
directors' stock option plan in January 2000 and we will submit the directors'
stock option plan to our stockholders for approval before completion of this
offering. We have reserved total of 300,000 shares of common stock for issuance
under the directors' plan. No shares have been issued under the directors'
plan. The directors' plan becomes effective on the date of this offering.

  Eligible Persons and Administration. The directors' plan provides for the
grant of nonstatutory stock options to nonemployee directors of CrossWorlds.
The directors' plan is designed to work automatically without administration.
However, the board of directors will administer the plan when necessary. When
conflicts of interest arise, it is expected that they will be addressed by
abstention of any interested director from both deliberations and voting on
matters in which that director has a personal interest.

  Option Terms. The directors' plan provides that each person who becomes a
nonemployee director of CrossWorlds after the effective date of this offering
will be granted a nonstatutory stock option to purchase 25,000 shares of common
stock on the date on which the person first becomes a nonemployee director of
CrossWorlds. On the date of CrossWorlds' annual stockholders meeting each year,
each nonemployee director of CrossWorlds will be granted an option to purchase
5,000 shares of common stock if, on the annual stockholders meeting date, the
director has served on CrossWorlds' board of directors for at least six months.

  The directors' plan sets neither a maximum nor a minimum number of shares for
which options may be granted to any one nonemployee director. The directors'
plan does specify the number of shares that may be included in any grant and
the method of making a grant.

  Non-Transferability of Options. No option granted under the directors' plan
is transferable by the option holder other than by will or the laws of descent
or distribution or under a qualified domestic relations order, and each option
is exercisable, during the lifetime of the option holder, only by that option
holder.

  Exercise Price and Other Option Terms. The directors' plan provides that each
option shall vest at the rate of 1/12 of the total number of shares subject to
the option per month. If a nonemployee director ceases

                                       56
<PAGE>


to serve as a director for reasons other than death or disability, the director
may, but only within 90 days after the date the director ceases to be a
director of CrossWorlds, exercise options granted under the directors' plan. If
the director does not exercise the option that the director was entitled to
exercise within the 90 day period, the option shall terminate.

  The exercise price of all stock options granted under the directors' plan
shall be equal to the fair market value of a share of CrossWorlds' common stock
on the date of grant of the option. Options granted under the directors' plan
have a term of ten years.

  Outstanding options will adjust if there is a stock split, stock dividend or
other similar change in capital structure.

  Change of Control. If we sell all or substantially all of our assets or merge
with another company or conduct another similar transaction, the successor
corporation will assume the options or substitute equivalent options. If the
acquiror does not assume or substitute the options, the options will terminate
upon completion of the acquisition if the options were not previously
exercised.

  Amendment and Termination. The board of directors may amend or terminate the
directors' plan. However, no action may adversely affect any outstanding option
and we must obtain stockholder approval for any amendment when required by
applicable law. If not terminated earlier, the directors' plan will have a term
of ten years.

  2000 Employee Stock Purchase Plan.

  Adoption and Reserved Shares. The board of directors adopted our 2000
employee stock purchase plan in January 2000 and we will submit the 2000
employee stock purchase plan to our stockholders for approval before completion
of this offering. We have reserved total of 750,000 shares of common stock for
issuance under the purchase plan, none of which has been issued as of the date
of this offering. The number of shares reserved for issuance under the purchase
plan will be subject to an automatic annual increase on the first day of each
of our fiscal years beginning in 2001 and ending in 2005 in an amount equal to
the lesser of:

  .  500,000 shares,

  .  2% of our outstanding common stock on the last day of the immediately
     preceding fiscal year, or

  .  a lesser number of shares as the board of directors determines.

  The purchase plan becomes effective on the date of this offering. Unless
terminated earlier by our board of directors, the purchase plan will terminate
in 2010.

  Offering Periods. The purchase plan, which is intended to qualify under
Section 423 of the Code, will be implemented in a series of overlapping
offering periods of approximately 24 months' duration. New offering periods,
other than the first offering period, will begin on May 1 and November 1 of
each year. Each offering period will consist of four consecutive purchase
periods of approximately six months' duration. The initial offering period is
expected to begin on the date of this offering and end on April 30, 2002. The
initial purchase period is expected to end on October 31, 2000.

  Administration. The board of directors or a committee appointed by the board
will administer the purchase plan. Employees of CrossWorlds, or of any
majority-owned subsidiary designated by the board, who work at least 20 hours a
week for a minimum of five months per year are eligible to participate in the
purchase plan.

  Plan Terms. The purchase plan permits eligible employees to purchase common
stock through payroll deductions, which may not exceed 15% of an employee's
compensation, at a price equal to the lower of 85%

                                       57
<PAGE>

of the fair market value of CrossWorlds' common stock at the beginning of each
offering period or at the end of each purchase period. Employees may end their
participation in the offering at any time during the offering period, and
participation ends automatically on termination of employment with CrossWorlds.

  An employee cannot be granted an option under the purchase plan if
immediately after the grant the employee would own stock or hold outstanding
options to purchase stock equaling 5% or more of the total voting power or
value of all classes of our stock or stock of our subsidiaries. An employee
cannot be granted an option under the purchase plan if the option would permit
an employee's rights to purchase stock under the purchase plan to grow at a
rate that exceeds $25,000 of the fair market value of the stock for each year
in which an option is outstanding. No employee may purchase more than 1,500
shares of common stock under the purchase plan in any one purchase period.

  In a merger of CrossWorlds with another corporation or a sale of
substantially all of CrossWorlds' assets, the purchase plan provides that the
successor corporation must assume or substitute an equivalent right for each
right to purchase stock under the purchase plan. However, our board of
directors will shorten any ongoing offering period so that employees' rights to
purchase stock under the purchase plan are able to be exercised before to the
transaction if the successor corporation refuses to assume each purchase right
or to substitute an equivalent right. Outstanding options will adjust if there
is a stock split, stock dividend or other similar change in capital structure.
The board of directors has the power to amend or terminate the purchase plan as
long as the action does not adversely affect any outstanding rights to purchase
stock under the plan. However, our board of directors may amend or terminate
the purchase plan or an offering period even if it would adversely affect
outstanding options to avoid our incurring adverse accounting charges.

1996 Stock Plan.

  Adoption and Initial Reserve. Our board of directors originally adopted and
our stockholders originally approved our 1996 stock plan in March 1996. The
1996 stock plan provides for the grant of incentive stock options to employees
and nonstatutory stock options to employees and consultants. As of December 31,
1999, 980,555 shares were reserved for issuance under the 1996 plan, but the
board of directors has determined that no future grants will be made under the
1996 plan.

  Option Terms. The terms of the options under the 1996 plan are generally the
same as those that may be issued under the 1997 plan, except for the following:

  .  only options may be granted out of the 1996 plan; and

  .  nonstatutory stock options granted under the 1996 plan are
     nontransferable in all cases and must generally be granted with an
     exercise price equal to at least 85% of the fair market value of our
     common stock on the date of grant.

  In a merger, reorganization or similar transaction involving CrossWorlds, the
successor corporation shall assume each outstanding option or shall substitute
an equivalent option, with appropriate adjustments made to both the price and
number of shares subject to each option. If the successor corporation does not
assume the options, then the outstanding options will be fully vested and
exercisable for a period of fifteen days following notice provided to the
option holder. Outstanding options will be adjusted for stock splits, stock
dividends or other similar changes in capital structure.

  The term of options granted under the 1996 plan is ten years from the date of
grant. Options granted under the 1996 plan must be exercised within three
months after the end of the option holder's status as an employee of
CrossWorlds, or within twelve months after the option holder's termination by
death or disability. Options granted under the 1996 plan will remain
outstanding in compliance with their terms.

1999 Executive Stock Plan.

  Adoption and Initial Reserve. Our board of directors adopted the 1999
executive stock plan and our stockholders approved the 1999 executive stock
plan in October 1999. We have reserved total of 3,500,000 shares

                                       58
<PAGE>


of common stock for issuance under the 1999 plan. As of December 31, 1999,
2,859,525 options were issued and outstanding or committed for issuance and
640,475 shares remained available for future option or stock purchase right
grants. We do not intend to grant any additional options or stock purchase
rights under the 1999 plan after the date of this offering. Unless terminated
earlier, the 1999 plan will terminate in October 2009.

  Other Terms. The terms of options and stock purchase rights under the 1999
plan are generally the same as those that may be issued under the 1997 plan,
except for the following:

  .  the 1999 plan does not impose a limitation on the number of shares
     subject to options and stock purchase rights that may be issued to any
     individual employee,

  .  nonstatutory stock options and stock purchase rights may not be granted
     to non-employee directors under the 1999 plan after the date of this
     offering, and

  .  nonstatutory stock options and stock purchase rights granted under the
     1999 plan are nontransferable in all cases and must generally be granted
     with an exercise price or purchase price equal to at least 85% of the
     fair market value of our common stock on the date of grant.

  If we sell all or substantially all of our assets or merge with or into
another corporation, then the successor corporation may assume each option and
stock purchase right or substitute an equivalent option or stock purchase
right. However, if the successor corporation does not agree to this assumption
or substitution, the option or stock purchase right shall become fully vested
and exercisable for a period of fifteen days from the date the option holder
received notice and will terminate following the fifteen day period. Upon the
closing of the transaction, outstanding repurchase rights will terminate unless
assigned to the successor corporation. The board of directors may amend, modify
or terminate the 1999 plan at any time as long as any amendment, modification
or termination does not impair vesting rights of plan participants and provided
that stockholder approval shall be required for an amendment to the extent
required by applicable law.

Limitation of Liability and Indemnification Matters

  As permitted by Delaware law, CrossWorlds has included in its certificate of
incorporation a provision to eliminate the personal liability of its officers
and directors for money damages for breach or alleged breach of their fiduciary
duties as officers or directors, subject to specified exceptions. CrossWorlds'
bylaws provide that CrossWorlds is required to indemnify its officers and
directors under circumstances in which indemnification would otherwise be
discretionary. CrossWorlds is required to advance expenses to its officers and
directors as they incur them in proceedings in which they may be indemnified.

  CrossWorlds has entered into indemnification agreements with its officers and
directors containing provisions that are broader than the specific
indemnification provisions provided by Delaware law. The indemnification
agreements require CrossWorlds to:

  .  indemnify its officers and directors against liabilities that may arise
     because of their status or service as officers and directors, other than
     liabilities arising from willful misconduct of a culpable nature;

  .  to advance their expenses incurred as a result of any proceeding against
     them for which they could be indemnified; and

  .  to obtain directors' and officers' insurance if available on reasonable
     terms.

  At present, CrossWorlds is not aware of any pending or threatened litigation
or proceeding involving a director, officer, employee or agent of CrossWorlds
in which indemnification would be required or permitted. CrossWorlds is not
aware of any threatened litigation or proceeding that might result in a claim
for indemnification. CrossWorlds believes that its charter provisions and
indemnification agreements are necessary to attract and retain qualified
persons as directors and officers.

 Change of Control Agreements

  On January 27, 2000, CrossWorlds' board of directors approved a change of
control agreement with CrossWorlds' executive officers. Under the terms of the
agreement, 25% of each officer's remaining unvested options or shares of
restricted stock shall vest upon a change of control of CrossWorlds.

                                       60
<PAGE>


  When options or restricted shares are assumed by a successor corporation,
officers will receive the following accelerated vesting and severance payments:

  .  if the officer is involuntarily terminated within one year of the change
     of control, vesting of her shares may occur, under the terms of the
     change of control agreement. The vesting is subject to the restrictions
     described in the change of control agreement or applicable stock option
     plan;

  .  outstanding awards under the 1996 and 1997 stock plans or the 1999
     executive stock plan shall become immediately vested and exercisable.
     The amount exercisable shall be equal to twelve months of further
     vesting of each award at the rate specified in the applicable stock
     option or stock purchase agreement;

  .  if involuntarily terminated under the terms of the change of control
     agreement within one year of the change of control, the officer may be
     entitled to six months of regular monthly salary plus target bonus, and
     six months of consolidated omnibus budget reconciliation act payments.

  Alfred J. Amoroso Employment Agreement -- Basic Compensation

  On October 5, 1999, CrossWorlds and Alfred J. Amoroso entered into an
employment agreement under which Mr. Amoroso became CrossWorlds' president and
chief executive officer. This employment agreement established:

  . Mr. Amoroso's base salary at $41,666.66 per month, and

  . provides for a sign-on bonus of $400,000 to be paid on or before March 1,

Mr. Amoroso became eligible for a pro rata target bonus of $250,000 based on
the number of weeks of actual employment in 1999 and a full annual target bonus
of $250,000 for the year 2000. Mr. Amoroso will be eligible to receive an

  CrossWorlds will also provide Mr. Amoroso with relocation expenses and
temporary living costs:

  . temporary living costs are currently anticipated to total $200,000 to

  . a moving assistance loan of $1,500,000.

The loan is a non-recourse secured promissory note. The principal and interest
will be forgiven in equal monthly installments over a period of 48 months,
beginning the date of his employment and continuing for the term of his
employment. CrossWorlds will also make periodic bonus payments to Mr. Amoroso.
These bonus payments, after taxes, are intended to pay for Mr. Amoroso's tax
payments and interest on the loan, relocation expenses and temporary living
costs. If Mr. Amoroso is terminated, or if he resigns under the conditions
listed below, CrossWorlds will forgive an additional 12 months of loan and
accumulated interest payments.

which vest monthly in equal installments over 48 months. Upon the effectiveness
of this offering, the vesting of these shares shall accelerate and CrossWorlds'
repurchase right will lapse.

  Alfred J. Amoroso Employment Agreement -- Severance Benefits

  If Mr. Amoroso's employment is terminated, or if he resigns under the
conditions listed below, in the first year of employment, then 50% of the
shares will vest on the date of termination.

  Following the first year of Mr. Amoroso's employment, if Mr. Amoroso's
employment is terminated without a determination by CrossWorlds' board of
directors that Mr. Amoroso has engaged in:

    materially reduces his duties or level of responsibility; or

    employment by more than 35 miles from his then current office;

then Mr. Amoroso shall vest in that number of shares that would have vested
over the next 12 months from the date of termination. If Mr. Amoroso's
employment with CrossWorlds is terminated, or if he resigns under the
conditions listed above, then CrossWorlds shall pay Mr. Amoroso a lump sum
severance equal to the sum of (a) twelve months of his base salary plus (b) his
annual target bonus, together with one year of medical insurance premium
payments for him and his eligible dependents. CrossWorlds will also forgive
Mr. Amoroso's repayment of the moving assistance loan for twelve months.

employment, then each of his outstanding options will become fully vested and
CrossWorlds' repurchase right will lapse.

Under this agreement we issued convertible

                                       63
<PAGE>

promissory notes bearing interest at 8% each year, the principal amount of
which was convertible into shares of series E preferred stock.

  Under the agreement, Ms. Garnett loaned to CrossWorlds $4,650,000; Mr.
Ludwick loaned to CrossWorlds $250,000; and Mr. Gluck loaned to CrossWorlds
$100,000. In January 1999, the interest due under the notes was paid in cash
and the principal amount of the notes was converted into shares of series E
preferred stock.

  Since March 1996, we have issued and sold shares of our common stock and
granted options to purchase common stock to our employees, directors and
consultants.

                             PRINCIPAL STOCKHOLDERS

  This table presents information about the beneficial ownership of our common
stock as of December 31, 1999. The table also contains information regarding
beneficial ownership, as adjusted to reflect the sale of common stock in this
offering and the conversion of all outstanding shares of preferred stock into
shares of common stock. Specifically, the table reflects beneficial ownership
information regarding:

  . each of our directors;

  . our chief executive officer;

  . the other most highly compensated executive officers and Kevin
    Fitzgerald;

  . all directors and executive officers of CrossWorlds as a group; and

  . each person who is known by us to own beneficially more than 5% of
    CrossWorlds' common stock.

  Except as otherwise noted, the executive officers, directors and stockholders
identified in the table can be reached at the principal offices of CrossWorlds.

  This table assumes no exercise of the underwriters' over-allotment option.
Except under applicable community property laws or as indicated in the
footnotes to this table, each stockholder in the table has sole voting and
investment power over all shares of common stock identified in the table as
beneficially owned by that stockholder.

  Beneficial ownership is determined under the rules of the Securities and
Exchange Commission, based on factors including voting and investment power
over shares. Shares of common stock subject to options that are currently
exercisable or exercisable within 60 days of December 31, 1999 are considered
to be outstanding and to be beneficially owned by the person holding those
options for the purpose of computing the percentage ownership of that person.
These shares are not treated as outstanding for the purpose of computing the
percentage ownership of any other person.

                             PRIVATE PLACEMENT

  CrossWorlds has entered into a stock purchase agreement with The Dow Chemical
Company in which CrossWorlds agreed to sell shares of common stock equal to
$2,000,000 divided by the initial public offering price less the underwriting
discount, for a per share price equal to the initial public offering price less
the underwriting discount. CrossWorlds also entered into a stock purchase
agreement with Delphi Automotive in which CrossWorlds agreed to sell shares of
common stock equal to $2,000,000 divided by the initial public offering price
less the underwriting discount, for a per share price equal to the initial
public offering price less the underwriting discount. In addition, CrossWorlds
entered into a stock purchase agreement with Electronic Data Systems
Corporation in which CrossWorlds agreed to sell shares of common stock equal to
the lower of:

 . two percent of the outstanding capital stock of CrossWorlds after this
   offering, or

 . the number of shares of common stock equal to $10,000,000 divided by the
   initial public offering minus the underwriting discount.

  At an assumed initial public offering price of $15.00, we will sell 143,369
shares of common stock to The Dow Chemical Company, 143,369 shares of common
stock to Delphi Automotive and 501,700 shares of common stock to Electronic
Data Systems Corporation at a per share price of 13.95. The private placement
of a total of 788,438 shares of our common stock to The Dow Chemical Company,
Delphi Automotive and Electronic Data Systems Corporation would occur at the
same time as this offering.

                          DESCRIPTION OF CAPITAL STOCK

  Upon the completion of this offering, CrossWorlds will be authorized to issue
150,000,000 shares of common stock. Upon the closing of the offering, all
outstanding shares of preferred stock except for series D preferred stock will
be converted into one share of common stock and automatically retired. Upon the
closing of the offering, each share of series D will be converted into
approximately 1.2 shares of common stock and automatically retired.

Common Stock

  As of December 31, 1999, there were 19,696,563 shares of common stock
outstanding, adjusted to reflect the conversion of all outstanding shares of
preferred stock. This calculation excludes the exercise of any outstanding
options or warrants into common stock, which are held of record by 332
stockholders.

  Options to purchase an aggregate of 6,793,436 shares of common stock were
also outstanding as of December 31, 1999. Assuming no exercise of the
underwriters' overallotment option and no exercise of outstanding options under
CrossWorlds' stock plans, there will be 24,485,001 shares of stock outstanding,
after giving effect to the sale of the shares offered under the prospectus and
the shares sold in a private placement that will close at the same time as this
offering.

  The holders of common stock are entitled to one vote for each share held of
record on all matters submitted to a vote of the stockholders. Subject to
preferences that may be applicable to any outstanding preferred stock, holders
of common stock are entitled to receive dividends in proportion to their
ownership as may be declared by the board of directors out of funds legally
available for that purpose. In a liquidation, dissolution or winding up of
CrossWorlds, the holders of common stock are entitled to share in proportion to
their ownership in all assets remaining after payment of liabilities, subject
to the prior distribution rights of any outstanding preferred stock. The common
stock has no preemptive or conversion rights or other subscription rights. The
outstanding shares of common stock are, and the shares of common stock to be
issued upon completion of this offering will be, fully paid and non-assessable.



Warrants

  As of December 31, 1999, there were warrants outstanding to purchase an
aggregate of 343,431 shares of common stock. Generally, each warrant contains
provisions for adjustment of the exercise price and of the aggregate number of
shares issuable upon the exercise of the warrant for stock dividends, stock
splits, reorganizations, reclassifications and consolidations.

  Additionally, after December 31, 1999, our board approved the issuance of
warrants to purchase 199,996 shares of common stock at a weighted average
exercise price of $11.00 per share. Generally, each warrant contains provisions
for the adjustment of the exercise price and of the aggregate number of shares
issuable upon the exercise of the warrant for stock dividends, stock splits,
reorganizations, reclassifications and consolidations.

Registration Rights

   Assuming the conversion of all outstanding preferred stock after this
offering, and including warrants to purchase 337,097 shares of common stock,
the holders of 18,220,000 shares of common stock are entitled to rights to
register their shares under the Securities Act. These rights are provided under
the terms of an agreement between CrossWorlds and the holders of the
registrable securities.

  Subject to the limitations in the agreement, the holders of at least 30% of
the registrable securities, or Quantum Industrial Partners LDC or SFM Domestic
Investments LLC may require, on two occasions, that CrossWorlds use its best
efforts to register the securities for public resale.

  If CrossWorlds registers any of its common stock, either for its own account
or for the account of other security holders, the holders of registrable
securities are entitled to include their shares of common stock in the
registration, subject to the ability of the underwriters to limit the number of
shares included in the

                                       67
<PAGE>


offering. The holders of registrable securities may also require, on no more
than two occasions in a twelve-month period, that CrossWorlds register their
shares for resale on Form S-3 so long as the value of the securities to be
registered is at least $1,000,000. CrossWorlds will be responsible for paying
all registration expenses, and the holders of registrable securities selling
their shares will be responsible for paying all selling expenses.

Delaware Anti-Takeover Law and Charter and Bylaw Provisions

  Provisions of Delaware law and CrossWorlds' charter documents could make the
acquisition of CrossWorlds and the removal of incumbent officers and directors
more difficult. These provisions are expected to discourage coercive takeover
practices and inadequate takeover bids and to encourage persons seeking to
acquire control of CrossWorlds to negotiate with us first. CrossWorlds believes
that the benefits of this increased protection outweigh the disadvantages
because negotiation of these proposals could result in an improvement of their
terms.

  CrossWorlds is subject to the provisions of Section 203 of the Delaware law.
In general, the statute prohibits a publicly-held Delaware corporation from
engaging in a business combination with an interested stockholder for a period
of three years after the date that the person became an interested stockholder.
This prohibition does not apply to a business combination or a transaction
which is approved in advance. Generally, a business combination with an
interested stockholder would include a merger, asset or stock sale, or other
transaction resulting in a financial benefit to the stockholder. Generally, an
interested stockholder is a person who, together with affiliates and
associates, owns, or within three years prior, did own, 15% or more of the
corporation's voting stock. These provisions may have the effect of delaying,
deferring or preventing a change in control of CrossWorlds without further
action by the stockholders.

  Our certificate of incorporation forces shareholders to take actions at
meetings rather than by written consent. The certificate of incorporation also
provides that directors are elected by the vote of the shareholders, and limits
minority stockholders' ability to elect their nominees to the board. Our bylaws
provide that special meetings of stockholders can be called only by the board
of directors, by the chairman of the board of directors or by the president.
Moreover, the business permitted to be conducted at any special meeting of
stockholders is limited by Delaware Law to the business described in the notice
of the meeting. Our bylaws also establish rules for stockholder submission of
candidates for election to the board of directors, and establish rules for
business to be raised at stockholder meetings. The rules include advance notice
procedures for director nominations. These provisions would make it difficult
for stockholders to call a special meeting to take corporate action, and may
have the effect of delaying, deferring or preventing a change in control of
CrossWorlds.

Transfer Agent and Registrar

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

                        SHARES ELIGIBLE FOR FUTURE SALE

Sales in the Public Market Could Hurt the Market Price of CrossWorlds' Stock

  Before this offering, there has been no market for CrossWorlds common stock.
Future sales of substantial amounts of common stock in the public market could
adversely affect prevailing market prices. Furthermore, only a limited number
of shares will be available for sale shortly after this offering because of
contractual and legal restrictions on resale, as described below. Consequently,
sales of substantial amounts of CrossWorlds common stock in the public market
after the restrictions lapse could adversely affect the prevailing market price
and CrossWorlds' ability to raise equity capital in the future.

What Shares are Outstanding and What Shares are Freely Tradeable

  Upon completion of the offering, we will have 24,485,001 shares of common
stock outstanding. This assumes no exercise of the underwriters' over allotment
option, and no exercise of outstanding options or warrants to purchase common
stock after December 31, 1999. The 4,000,000 shares sold in the offering, plus
any shares issued upon exercise of the underwriters' overallotment option, will
be freely tradable without restriction under the Securities Act, unless
purchased by affiliates of CrossWorlds as affiliates is defined in Rule 144
under the Securities Act.

What Shares are Restricted and Not Freely Tradeable

  The remaining 20,485,001 shares outstanding are restricted securities within
the meaning of Rule 144 under the Securities Act. Restricted securities may be
sold in the public market only if registered or if they qualify for an
exemption from registration under Rules 144, 144(k) or 701 of the Securities
Act, which are summarized below. Sales of the restricted securities in the
public market, or the availability of these shares for sale, could adversely
affect the market price of the common stock.

Effects of the 180-day Lockup Agreement on Sales of Stock

  Stockholders of CrossWorlds holding an aggregate of 20,485,001 shares of
common stock are subject to lock-up agreements. These agreements generally
provide that, without the prior written consent of Chase Securities Inc.,
stockholders will not transfer or dispose of, directly or indirectly, any
shares of our common stock or any securities convertible into our shares. This
restriction will be applicable for a period of 180 days after the effective
date of this registration statement. As a result of these contractual
restrictions, shares subject to lock-up agreements will not be saleable until
these agreements expire or are waived by the designated underwriters'
representative, despite possible earlier eligibility for sale under the
provisions of Rules 144, 144(k) and 701. Taking into account the lock-up
agreements, and assuming Chase Securities Inc. does not release stockholders
from these agreements, these shares will be eligible for sale in the public
market:

  .  beginning on the effective date of this prospectus, only the shares sold
     in the offering will be immediately available for sale in the public
     market;

  .  beginning 180 days after the effective date, approximately 19,696,563
     shares will be eligible for sale under federal securities laws, of which
     all but 10,111,168 shares are held by affiliates; and

  .  beginning one year after the effective date, approximately 788,438
     shares will be eligible for sale under federal securities laws.

Effects of Rule 144 on Sales of Restricted Shares

  Under Rule 144, a person who has beneficially owned restricted securities for
at least one year generally is entitled to sell, within any three-month period,
a number of shares that does not exceed the greater of:

  .  one percent of the number of shares of common stock then outstanding,
     which will equal approximately 244,850 shares immediately after the
     offering; or

                                       69
<PAGE>

  .  the average weekly trading volume of the common stock during the four
     calendar weeks preceding the sale.

  Sales under Rule 144 are also subject to manner of sale provisions and notice
requirements and to the availability of current public information about
CrossWorlds. Under Rule 144(k), a person who is not considered to have been an
affiliate of CrossWorlds at any time during the three months preceding a sale,
and who has beneficially owned the shares proposed to be sold for at least two
years, is entitled to sell these shares without complying with the manner of
sale, public information, volume limitation or notice provisions of Rule 144.

 Effects of Rule 701 on Rules of Restricted Shares

  CrossWorlds employees holding common stock or stock options may not sell
shares acquired upon exercise until 180 days after the effective date.
Beginning 180 days after the effective date, any employee, officer or director
of or consultant to CrossWorlds who purchased shares under a written
compensatory plan or contract may be entitled to rely on the resale provisions
of Rule 701. Rule 701 permits affiliates to sell their Rule 701 shares under
Rule 144 without complying with the holding period requirements of Rule 144.
Rule 701 further provides that non-affiliates may sell these shares in reliance
on Rule 144 without having to comply with the holding period, public
information, volume limitation or notice provisions of Rule 144.

 Registration of Shares Issued Under CrossWorlds' Employee Benefits Plans

  CrossWorlds intends to file registration statements under the Securities Act
as promptly as possible after the effective date to register shares to be
issued under CrossWorlds' employee benefit plans. As a result, any options
exercised under the 1997 stock plan or any other benefit plan after the
effectiveness of these registration statements will also be freely tradable in
the public market, except that shares held by affiliates will still be subject
to the volume limitation, manner of sale, notice and public information
requirements of Rule 144 unless otherwise resalable under Rule 701.

 Outstanding Options at December 31, 1999

  As of December 31, 1999, there were outstanding options for the purchase of
6,793,436 shares, of which 3,310,545 options were exercisable. No shares have
been issued to date under our purchase plan or directors plan.

Conditions to the Underwriters' Obligations

  The underwriting agreement provides that the obligations of the underwriters
are subject to conditions precedent, including the absence of any material
adverse change in our business and the receipt of certificates, opinions and
letters from us, our counsel and independent auditors. The underwriters are
committed to purchase all shares of common stock offered in this prospectus if
any shares are purchased.

Pricing of the Stock

  The underwriters propose to offer the shares of common stock directly to the
public at the public offering price on the cover page of this prospectus and to
dealers at that price less a concession not in excess of $      per share. The
underwriters may allow and the dealers may reallow a concession not in excess
of $      per share to other dealers. After the public offering of the shares,
the underwriters may change the offering price, concession and reallowance to
dealers.

The Underwriters' Option to Purchase More Shares

  We have granted to the underwriters an option, exercisable during the 30-day
period after the date of this prospectus, to purchase up to 600,000 additional
shares of common stock at the same price per share as we will receive for the
4,000,000 shares that the underwriters have agreed to purchase. If the
underwriters exercise this option, each underwriter will have a commitment to
purchase approximately the same percentage of additional shares that the number
of shares of common stock to be purchased by it shown in the above table
represents as a percentage of the 4,000,000 shares offered by this prospectus.
We will be obligated to sell shares to the underwriters to the extent the
option is exercised. The underwriters may exercise this option only to cover
over-allotments of common stock offered in this prospectus.

Factors in Pricing Our Stock in the Offering

  Before this offering, there has been no public market for our common stock.
The initial public offering price for the common stock will be determined
through negotiation between us and the representatives of the underwriters.
Factors to be considered in the negotiation include:

  .  prevailing market conditions,

  .  our financial information,

  .  market valuations of other companies that we and the representatives of
     the underwriters believe to be comparable to us,

  .  estimates of our business potential and

  .  the present state of our development.

Market Stabilization Activities

  Persons participating in this offering may over-allot or engage in
transactions which stabilize or maintain the market price of the common stock
at levels above those which might otherwise prevail in the open market. These
persons may enter stabilizing bids or engage in syndicate covering
transactions. A stabilizing bid is a bid for or the purchase of common stock
for the purpose of fixing or maintaining the price of the common stock. A
syndicate covering transaction is a bid for or the purchase of stock on behalf
of the underwriters to reduce a short position incurred by the underwriters in
connection with this offering; a short position results when an underwriter
sells more shares than it has committed to purchase. These transactions may
occur on the Nasdaq National Market, in the over-the-counter market. These
transactions, if commenced, may be discontinued at any time.

  Underwriters and selling group members, if any, who are qualified market
makers on the Nasdaq National Market may engage in passive market making
transactions in our common stock on the Nasdaq National Market in compliance
with Rule 103 of Regulation M under the Securities Exchange Act of 1934. During
the business day before the pricing of the offering before the beginning of
offers or sales of our

                                       72

common stock, passive market makers must comply with applicable volume and
price limitations and must be identified. In general, a passive market maker
must display its bid at a price not in excess of the highest independent bid of
that security; if all independent bids are lowered below the passive market
maker's bid, however, the bid must then be lowered when purchase limits are
exceeded.

Thomas Weisel Partners LLC

  Thomas Weisel Partners LLC, one of the representatives of the underwriters,
was organized and registered as a broker-dealer in December 1998. Since
December 1998, Thomas Weisel Partners has been named as a lead or co-manager on
110 filed public offerings of equity securities, of which 79 have been
completed, and has acted as a syndicate member in an additional 54 public
offerings of equity securities. Thomas Weisel Partners does not have any
material relationship with us or any of our officers, directors or other
controlling persons, with the exception of its contractual relationship with us
under the underwriting agreement entered into for this offering.

Offering Expenses

  We estimate that the total expenses of this offering, excluding underwriting
discounts and commissions, will be approximately $1,200,000.

Directed Shares Program and Rights to Purchase Shares in the Offering

  At our request, the underwriters have reserved for sale, at the initial
public offering price, up to (1) 200,000 shares for persons that are affiliated
with companies with whom we have a business relationship, such as executives of
companies that market, sell or promote our products and (2) up to approximately
135,000 additional shares for five current stockholders under their pre-
existing contractual rights to purchase shares in this offering. The shares
sold by exercise of the contractual rights will be subject to a 180-day lock-up
agreement. The sales of these shares will only be made under this prospectus.
The stockholders who hold these pre-existing contractual rights are ATGF II,
Litton Master Trust, James Stableford, Emeric McDonald and Anthony Ciulla. The
number of shares of our common stock available for sale to the public will be
reduced if these individuals and entities purchase these reserved shares. Any
reserved shares that are not purchased by these persons will be offered by the
underwriters to the public on the same basis as the other shares in this
offering.

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors
CrossWorlds Software, Inc.:

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

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

In our opinion, the consolidated financial statements referred to above present
fairly, in all material respects, the financial position of CrossWorlds
Software, Inc. and subsidiaries for each of the years in the three-year period
ended December 31, 1999, in conformity with generally accepted accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) Organization and Significant Accounting Policies

 (a) Description of Business

  CrossWorlds Software, Inc. (the Company) develops, produces, markets and
implements e-business infrastructure software. The Company is headquartered in
Burlingame, California and operates foreign subsidiaries in Germany, the United
Kingdom and France. The majority of the Company's revenues are derived from
domestic sales which were 80%, 77% and 86% for 1997, 1998 and 1999 of total
revenues, respectively. Substantially all of the Company's sales are made in
U.S. dollars.

 (b) Principles of Consolidation

  The accompanying consolidated financial statements include the accounts of
the Company and its wholly owned subsidiaries. All intercompany balances and
transactions have been eliminated in consolidation.

 (c) Foreign Currency

  The Company considers the functional currency of its foreign subsidiaries to
be the U.S. dollar. Accordingly, the foreign subsidiaries' financial statements
are remeasured into U.S. dollars using the historical exchange rate for
nonmonetary items and the current exchange rate for monetary items.
Remeasurement gains and losses, as well as transaction gains and losses, are
included in the determination of net loss and have been immaterial to date.

 (d) Cash and Cash Equivalents

  The Company considers all highly liquid instruments with a remaining maturity
on the date of purchase of three months or less to be cash equivalents, which
consist primarily of money market funds and overnight deposits.

 (e) Property and Equipment

  Property and equipment are carried at cost less accumulated depreciation.
Depreciation is calculated using the straight-line method over the estimated
useful lives of the respective assets, generally two to five years. Leasehold
improvements are amortized over the lesser of the asset's useful life or the
remaining lease term.

  The Company evaluates long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. If such assets are considered to be impaired, the impairment to
be recognized is measured as the difference between the carrying amount of the
property and equipment and its fair value. To date, the Company has made no
adjustments to the carrying values of its long-lived assets.

 (f) Software Development Costs

  Software development costs associated with new products and enhancements to
existing products are expensed as incurred until technological feasibility is
established upon completion of a working model. To date, the Company's software
development has been completed concurrent with the establishment of
technological feasibility, and, accordingly, no costs have been capitalized.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)
 (g) Concentrations of Credit Risk and Major Customers

  The Company's cash and cash equivalents are principally on deposit in a
short-term asset management account at a large bank. Accounts receivable
potentially subject the Company to concentrations of credit risk. The Company's
customer base is comprised primarily of large companies. The Company generally
does not require collateral for accounts receivable. When required, the Company
maintains allowances for credit losses, and to date such losses have been
within management's expectations. Information regarding sales to major
customers follows (items with an * indicate percentage was less than 10%):

</TABLE>

 (h) Fair Value of Financial Instruments

  The fair value of the Company's cash, accounts receivable, accounts payable,
and borrowings approximate their carrying values due to their short maturity or
variable-rate structure.

 (i) Use of Estimates

  The preparation of consolidated 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 liabilities at the date of the consolidated financial
statements and the reported amounts of revenue and expenses during the
reporting period. Actual results could differ from those estimates.

 (j) Revenue Recognition

  The Company's software arrangements typically involve significant production,
customization, or modification of the software, or services that are essential
to the functionality of the software and, as a result, software license revenue
for the entire arrangement is recognized using the percentage-of-completion
method. Progress toward completion is generally measured by achieving certain
standard and objectively verifiable milestones present in each project. These
milestones typically require customer acceptance of a deliverable. In certain
instances, the Company may recognize software license revenue upon delivery and
when persuasive evidence of an arrangement exists, provided the fee is fixed
and determinable, acceptance is certain, collection is probable, and the
arrangement does not involve significant production, customization, or
modification of the software or services that are essential to the
functionality of the software; however, software license revenue recognized in
this manner has been immaterial to date. In the event costs to complete a
contract are expected to exceed anticipated revenue, a loss is accrued. In
certain circumstances where the Company is unable to estimate the amount of
effort required to customize or implement the software license, revenue is
recognized using the completed contract method. To date, no amounts have

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

been recognized under the completed contract method. Other consulting and
service revenue is recognized as the services are performed. Maintenance
revenue from customer support and product upgrades, including maintenance
bundled with original software licenses, are deferred and recognized ratably
over the term of the maintenance agreement, typically 12 months. When the
Company enters into software arrangements with resellers, the Company does not
recognize revenue until the reseller demonstrates it has entered into an
arrangement with an end user that satisfies the Company's revenue recognition
criteria. When our services are essential to the implementation of the
reseller's software, the software license revenue for the arrangement is
recognized using the percentage-of-completion method. The Company recognizes
revenue in accordance with the American Institute of Certified Public
Accountants' (AICPA) Statement of Position (SOP) 97-2, Software Revenue
Recognition.

  In December 1998, the AcSEC issued SOP 98-9, Software Revenue Recognition,
with Respect to Certain Arrangements, which requires recognition of revenue
using the "residual method" in a multiple-element arrangement when fair value
does not exist for one or more of the undelivered elements in the arrangement.
Under the residual method, the total fair value of the undelivered elements is
deferred and subsequently recognized in accordance with SOP 97-2. The Company
adopted SOP 98-9 on January 1, 2000, and does not expect adoption to have a
material effect on its consolidated financial position or results of
operations.

 (k) Accounts receivable

  The Company bills for software licenses and maintenance fees at the inception
of the contract. These arrangements typically allow the Company to bill amounts
in excess of revenue recognized. Amounts billed in excess of revenue recognized
are recorded as deferred revenue. Consulting and service fees are billed
monthly based on time and expenses incurred. Service revenue recognized in
excess of amounts billed was $393,731 at December 31, 1999. The Company's
contracts typically do not contain retainage provisions and all amounts due
under the contracts are anticipated to be collected within 12 months. At
December 31, 1999, there are no accounts receivable that are subject to
contract claims or uncertainties.

 (l) Stock-Based Compensation

  The Company accounts for its stock-based compensation plans using the
intrinsic value method. Deferred stock-based compensation expense is recorded
if, on the date of grant, the current market value of the underlying stock
exceeds the exercise price. The Company amortizes deferred stock-based
compensation in accordance with Financial Accounting Standards Board (FASB)
Interpretation No. 28.

  The Company uses the fair value method to account for stock options and other
equity instruments issued to nonemployees.

 (m) Income Taxes

  The Company accounts for income taxes using the asset and liability method.
Deferred income taxes are recognized by applying enacted statutory tax rates
applicable to future years to differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax
bases and operating loss and tax credit carryforwards. The effect on deferred
tax assets and liabilities of a change in tax rates is recognized in income in
the period that includes the enactment date. The measurement of deferred tax
assets is reduced, if necessary, by a valuation allowance for any tax benefits
for which future realization is uncertain.

 (n) Comprehensive Loss

  The Company does not have any components of comprehensive income,
consequently comprehensive loss consists entirely of net loss for all periods
presented.

 (o) Net Loss Per Share

  Basic net loss per share is computed using the weighted-average number of
outstanding shares of common stock, excluding common stock subject to
repurchase. Diluted net loss per share is computed using the weighted-average
number of outstanding shares of common stock and, when dilutive, potential
common shares from options and warrants to purchase common stock and common
stock subject to repurchase using the treasury stock method, and from
convertible securities using the as-if converted basis. All potential common
shares have been excluded from the computation of diluted net loss per share
for all periods presented because the effect would have been antidilutive.


  Diluted net loss per share does not include the effect of the following
antidilutive common equivalent shares:

 (q) Accounting for Derivative Instruments and Hedging Activities

  In June 1998, the FASB issued SFAS No. 133, Accounting for Derivative
Instruments and Hedging Activities. SFAS No. 133 establishes accounting and
reporting standards for derivative instruments, including certain derivative
instruments embedded in other contracts, (collectively referred to as
derivatives) and for hedging activities. It requires that an entity recognize
all derivatives as either assets or liabilities in the statement of financial
position and measure those instruments at fair value. For a derivative not
designated as a hedging instrument, changes in the fair value of the derivative
are recognized in earnings in the period

of change. This statement will be effective for all annual and interim periods
beginning after January 1, 2001. Management does not believe the adoption of
SFAS No. 133 will have a material effect on the Company's consolidated
financial position or results of operations.

 (r) Advertising Costs

  The Company expenses advertising costs as incurred. Advertising expense was
approximately $394,000, $2,004,000 and $46,000 for the years ended December 31,
1997, 1998 and 1999, respectively.

 (s) Initial Public Offering, Private Placement, Unaudited Pro Forma Balance
Sheet and Net Loss Per Share

  The Board of Directors of the Company authorized the filing of a registration
statement with the Securities and Exchange Commission (SEC) that would permit
the Company to sell shares of the Company's common stock in connection with a
proposed initial public offering (IPO). The Company has also entered into
agreements to sell common shares in a private placement concurrent with the
IPO. If the IPO is consummated under the terms presently anticipated, all
outstanding shares of the Company's convertible preferred stock will
automatically convert on a one-for-one basis, subject to certain antidilution
provisions, upon the closing of the IPO. The pro forma balance sheet
information reflects the conversion of all of the convertible preferred stock
as if it had occurred on December 31, 1999.

  Pro forma net loss per share for the years ended December 31, 1997, 1998 and
1999, is computed using the weighted average number of common shares
outstanding, including the pro forma effects of the automatic conversion of the
Company's convertible preferred stock into shares of the Company's common stock
effective upon the closing of the Company's IPO as if the conversion occurred
on January 1, 1997, or at the date of issuance, if later. Pro forma common
equivalent shares, comprised of incremental common shares issuable upon the
exercise of stock options and warrants as well as shares subject to repurchase
agreements are not included in pro forma diluted net loss per share because
they would be anti-dilutive.

(2) Property and Equipment

  Property and equipment as of December 31, 1998 and 1999 consisted of the

  Equipment under the capital lease aggregated $1,132,726 as of December 31,
1999. Accumulated amortization on the assets under the capital lease aggregated
$179,565 as of December 31, 1999.

(3) Long Term Debt

  On December 23, 1998 the Company entered into a Convertible Subordinated
Promissory Note Agreement (the Promissory Note Agreement) with certain
stockholders of the Company in the amount of $5,000,000. In accordance with the
terms of the Promissory Note Agreement, the entire amount plus accrued
interest, was converted into shares of convertible preferred stock in the
Company's Series E round of financing in January 1999.

  Outstanding borrowings under the equipment facilities agreements are secured
by all of the Company's assets. The working capital facility agreement
contained affirmative and negative covenants requiring, among other things, the
Company to maintain minimum levels of liquid assets, limit the Company's
ability to incur additional debt, pay cash dividends, or to purchase certain
assets. These covenants require the Company to restrict certain acquisitions,
mergers, consolidations, or similar transactions. In 1999, the Company issued
warrants to purchase 6,334 shares of common stock to the bank in exchange for
waivers of noncompliance with these covenants. The fair value of the warrants
are not material to the Company's consolidated operating results. As of
December 31, 1999, all amounts drawn under the working capital facility were
repaid.

  In connection with the Subordinated Loan Agreement, the Company issued a
warrant to the lender to purchase up to 126,666 shares of Series E preferred
stock at an exercise price of $6.00 per share. The warrant is exercisable on
the earlier of seven years after the date of issuance or three years after the
Company's initial public offering. Accordingly, the Company has reserved
126,666 shares of Series E preferred stock for issuance

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

upon the exercise of the warrant. The warrant had a fair value of $500,000 on
the date of grant, computed using the Black-Scholes pricing model with the
following assumptions: 60% volatility, zero dividends, a risk-free rate of 6.1%
and a contractual life of 7 years. The fair value of the warrant has been
recorded in equity and as a reduction of the carrying amount of the related
debt and will be amortized into interest expense over the debt term. Total
amortization expense for the year ended December 31, 1999 was $166,667.

(4) Commitments

 (a) Lease Commitment

  The Company leases its primary facility under a noncancelable operating lease
expiring in 2008. The Company also leases various facilities which serve as
sales offices in the United States, and subsidiary offices in France, Germany,
and the United Kingdom under noncancelable operating leases with expiration
dates ranging from February 1999 to February 2000. In addition, the Company
leases equipment under noncancelable operating leases expiring in December
2001. In conjunction with the facility lease, the Company issued a warrant for
the purchase of 33,333 shares of Series C preferred stock at an exercise price
equal to $6.00 per share. The warrant shall expire and no longer be exercisable
at the earlier of: (a) December 31, 2002; or (b) the merger or consolidation of
the Company with a third party or the sale of all or substantially all of the
Company's assets to a third party; or (c) the closing of an underwritten public
offering of shares of common stock of the Company. The fair value of the
warrant was not material to the Company's 1998 consolidated operating results.

  Future minimum lease payments as of December 31, 1999, are as follows:

vendors for certain licensed technology. The agreements include minimum royalty
payments of approximately $2.8 million and $2.0 million, respectively due
through June 2001 and June 2000, respectively.

  The Company expects to earn out its remaining minimum royalty obligations
associated with the technology with minimum royalty payments of approximately
$2.8 million due by June 2001 and has recognized the associated cost of license
commensurate with usage.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


  During the fourth quarter of 1999, the Company developed and began shipping
products which replaced the technology provided under the agreement associated
with the minimum royalty payments of $2.0 million due by June 2000. As a
result, the Company discontinued use of this licensed technology and recorded a
one-time charge to other expense for the remaining $1 million of unamortized
minimum royalties.

 (c) Employment Agreements

  In October 1999, the Company entered into an employment agreement with its
President and Chief Executive Officer. The agreement provided for a sign-on
bonus of $400,000 to be paid by March 1, 2000. The sign-on bonus was accrued
and charged to general expense in the fourth quarter of 1999. In addition, the
individual is eligible for a pro rata target bonus of $250,000 based on the
number of weeks of actual employment in 1999 and a full annual target bonus of
$250,000 for the year 2000. In addition, the Company will provide the
individual a moving assistance loan of $1.5 million pursuant to a secured
nonrecourse promissory note, which will be forgiven in equal monthly
installments over a period of 48 months as long as the individual remains
employed by the Company. No amounts have been borrowed through December 31,
1999.

  In January 2000, the Company entered into an employment agreement with its
Senior Vice President of Worldwide Sales. The agreement provides for a sign-on
bonus of $300,000 to be paid by March 1, 2000.

(5) Stockholders' Equity

 (a) Reverse Stock Split

  On October 1, 1999, the Company's Board of Directors authorized a 1 for 3
reverse stock split. The accompanying consolidated financial statements and
related notes have been retroactively restated to give effect to the reverse
stock split.

 (b) Convertible Preferred Stock

  In 1999, the Company sold 2,883,326 shares of Series E convertible preferred
stock at $6.00 per share for gross proceeds of $17,300,000. Included in the

  The rights, preferences, and privileges of the holders of Series A, B, C, D,
E and F convertible preferred stock are as follows:

  . Dividends are noncumulative and payable only upon declaration by the
    Company's Board of Directors at a rate of $0.0075, $0.06, $0.30, $0.75,
    $0.30 and $0.34 per share for Series A, B, C, D, E and F preferred stock,
    respectively.

  . Holders of Series A, B, C, D, E and F preferred stock have a liquidation
    preference of $0.15, $1.20, $6.00, $15.00, $6.00 and $6.81 per share,
    respectively, plus any declared but unpaid dividends.

  . Each share of Series A, B, C, D, E and F preferred stock is convertible
    at any time into one share of common stock at the option of the holder,
    subject to certain antidilution provisions. Each share of preferred stock
    automatically converts upon the earlier of the public offering of the
    Company's common stock with gross proceeds in excess of $25,000,000 or
    affirmative election of the holders of at least 66 2/3% of the
    outstanding shares. The Company has fully reserved shares of common stock
    for issuance upon the conversion of Series A, B, C, D, E and F preferred
    stock.

  . Each holder of preferred stock has voting rights equal to the number of
    shares of common stock into which such shares could be converted. In
    addition, the holders of Series A, B, C, D, E and F preferred stock vote
    as a single class.

 (c) Common Stock

  The Company has issued 2,417,798 shares of common stock to founders and
employees under restricted stock purchase agreements. Pursuant to the
agreements, the Company has the right to repurchase the unvested common stock
at its original purchase price in the event of voluntary or involuntary
termination of the stockholder for any reason. The repurchase rights expire
through the year 2001. Shares subject to repurchase totaled approximately
1,321,104, 681,312 and 155,245 as of December 31, 1997, 1998 and 1999 ,
respectively.

 (d) Common Stock Reserved

  The Company has reserved 36,443,583 shares of common stock for issuance under
its stock option plan, for warrants, and upon the conversion of outstanding
convertible preferred stock.

 (e) Stock Option Plan

  The Company is authorized to issue up to 9,473,193 shares in connection with
its 1996, 1997 and 1999 stock option plans (the Plans) to directors, employees,
and consultants. The Plans provide for the issuance of stock purchase rights,
incentive stock options, or nonstatutory stock options.

  Stock purchase rights are subject to a restricted stock purchase agreement
whereby the Company has the right to repurchase the stock at the original issue
price upon the voluntary or involuntary termination of the purchaser's
employment with the Company. The repurchase rights will lapse at a rate
determined by the stock plan administrator, but at a minimum rate of 20% per
year.

  Under the 1997 plan, the exercise price for incentive stock options is at
least 100% of the stock's fair market value on the date of grant for employees
owning less than 10% of the voting power of all classes of stock, and at least
110% of the fair market value on the date of grant for employees owning more
than 10% of the voting power of all classes of stock. For nonstatutory stock
options, the exercise price is also at least

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

110% of the fair market value on the date of grant for service providers owning
more than 10% of the voting power of all classes of stock and no less than 85%
of the fair market value on the date of grant for service providers owning less
than 10% of the voting power of all classes of stock.

  Options generally expire in 10 years; however, they may be limited to 5 years
if the optionee owns stock representing more than 10% of the Company. Vesting
periods are determined by the stock plan administrator and generally provide
for shares to vest over a 4-year period, with 12.5% of the award vesting after
6 months from the date of grant and then ratably vesting each month thereafter.

  The Company uses the intrinsic value method to account for its fixed option
plans issued to employees. Deferred stock-based compensation cost has been
recognized for its stock option plan for grants to employees when the fair
value of the underlying common stock on the grant date exceeds the exercise
price for each stock option. Deferred stock-based compensation is amortized
using the accelerated method set forth in Financial Accounting Standards Board
Interpretation No. 28. Had compensation cost for the Company's stock-based
compensation plan been determined consistent with SFAS No. 123 for all of the
Company's stock-based compensation plans, net loss (in thousands) and basic and
diluted net loss per share would have been as follows:

 (f) Warrants

  In October 1999, the Company issued 177,098 warrants, at $6.60 a share, to an
executive search firm for the recruitment of its Chief Executive Officer. The
warrants are immediately exercisable up to seven years from the date of
issuance. The warrants had a fair value of $750,000 on the date of the grant
using the Black-Scholes pricing model with the following assumptions: 60%
volatility, zero dividends, a risk-free rate of 5.21% and a contractual life of
7 years. The amount was recorded as operating expense during 1999.

(6) Income Taxes

  The Company has incurred significant losses since inception and has not
incurred any income tax expense to date. The 1999 income tax differed from the
amounts computed by applying the U.S. federal income tax rate of 34% to pretax
income as a result of the following:

utilize its net operating loss and tax credit carryforwards may be subject to
restriction pursuant to these provisions.

required to be set forth in those schedules is not applicable or is shown in
the financial statements or notes to the financial statements.

Item 17. Undertakings

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

  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, or otherwise, the registrant
has been advised that in the opinion of the Securities and Exchange Commission
indemnification is against public policy as expressed in the Act, and is, as a
result, unenforceable. If a claim for indemnification against these
liabilities, other than the payment by the registrant of expenses incurred or
paid by a director, officer, or controlling person of the registrant in the
successful defense of any action, suit or proceeding, is asserted by a
director, officer or controlling person for the securities being registered,
the registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the act and will be governed by the final adjudication
of this issue.

  The undersigned registrant hereby undertakes that:

  (1) For purposes of determining any liability under the Securities Act of
1933, the information omitted from the form of prospectus filed as part of
this Registration Statement in reliance upon Rule 430A and contained in a form
of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or
497(h) under the Securities Act shall be considered to be part of this
registration statement as of the time it was declared effective.

  (2) For the purpose of determining any liability under the Securities Act of
1933, each post-effective amendment that contains a form of prospectus shall
be considered to be a new Registration Statement relating to the securities
offered therein, and the offering of such securities at that time shall be
considered to be the initial bona fide offering thereof.

The Company proposes to grant to the Underwriters (as hereinafter defined) an
option to purchase up to 600,000 additional shares of Common Stock (herein
called the Option Stock and with the Underwritten Stock herein collectively
called the Stock).  The Common Stock is more fully described in the Registration

     The Company hereby confirms the agreements made with respect to the
purchase of the Stock by the several underwriters, for whom you are acting,
named in Schedule I hereto (herein collectively called the Underwriters, which
term shall also include any underwriter purchasing Stock pursuant to Section
3(b) hereof).  You represent and warrant that you have been authorized by each
of the other Underwriters to enter into this Agreement on its behalf and to act
for it in the manner herein provided.

amendment thereto, if any, including the related preliminary prospectus (meeting
the requirements of Rule 430A of the rules and regulations of the Commission)
heretofore filed by the Company with the Commission have been delivered to you.

     The term Registration Statement as used in this agreement shall mean such
registration statement, including all exhibits and financial statements, all
information omitted therefrom in reliance upon Rule 430A and contained in the
Prospectus referred to below, in the form in which it became effective, and any
registration statement filed pursuant to Rule 462(b) of the rules and
regulations of the Commission with respect to the Stock (herein called a Rule
462(b) registration statement), and, in the event of any amendment thereto after
the effective date of such registration statement (herein called the Effective
Date), shall also mean (from and after the effectiveness of such amendment) such
registration statement as so amended (including any Rule 462(b) registration
statement).  The term Prospectus as used in this Agreement shall mean the
prospectus relating to the Stock first filed with the Commission pursuant to
Rule 424(b) and Rule 430A (or if no such filing is required, as included in the
Registration Statement) and, in the event of any supplement or amendment to such
prospectus after

Commission of such supplement or the effectiveness of such amendment) such
prospectus as so supplemented or amended. The term Preliminary Prospectus as
used in this Agreement shall mean each preliminary prospectus included in such
registration statement prior to the time it becomes effective.

     The Registration Statement has been declared effective under the Securities
Act, and no post-effective amendment to the Registration Statement has been
filed as of the date of this Agreement. The Company has caused to be delivered
to you copies of each Preliminary Prospectus and has consented to the use of
such copies for the purposes permitted by the Securities Act.

authority to own or lease its properties and conduct its business as described
in the Registration Statement and the Prospectus and as being conducted, and is
duly qualified as a foreign corporation and in good standing in all
jurisdictions in which the character of the property owned or leased or the
nature of the business transacted by it makes qualification necessary (except

the business, properties, financial condition or results of operations of the
Company and its subsidiaries, taken as a whole).

               (ii)       Since the respective dates as of which information is
given in the Registration Statement and the Prospectus, there has not been any
materially adverse change in the business, properties, financial condition or

whether or not arising from transactions in the ordinary course of business,
other than as set forth in the Registration Statement and the Prospectus, and
since such dates, except in the ordinary course of business, neither the Company
nor any of its subsidiaries has entered into any material transaction not
referred to in the Registration Statement and the Prospectus.

respects, with the provisions of the Securities Act and the Securities Exchange
Act of 1934, as amended (herein called the Exchange Act) and the rules and

believe, that either it or any of its subsidiaries is not conducting business in
compliance with all applicable laws, rules and regulations of the jurisdictions
in which it is conducting business, including, without limitation, all
applicable local, state and federal environmental laws and regulations; except
where failure to be so in compliance would not have a material adverse effect on
the business, properties, financial condition or results of operations of the
Company and its subsidiaries, taken as a whole.

               (xxx)     Subsequent to the respective dates as of which
information is given in the Prospectus: (i) there has been no material adverse
change, or any development that could reasonably be expected to result in a

1974, as amended, and the regulations and published interpretations thereunder
(collectively, "ERISA")) established or maintained by the Company, its
subsidiaries or their "ERISA Affiliates" (as defined below) are in compliance in
all material respects with ERISA. "ERISA Affiliate" means, with respect to the
Company or a subsidiary, any member of any group of organizations described in
Sections 414(b),(c),(m) or (o) of the Internal Revenue Code of 1986, as amended,
and the regulations and published interpretations thereunder (the "Code") of

its subsidiaries or any of their ERISA

                                      -6-
<PAGE>

Affiliates. No "employee benefit plan" established or maintained by the Company,
its subsidiaries or any of their ERISA Affiliates, if such "employee benefit
plan" were terminated, would have any "amount of unfounded benefit liabilities"
(as defined under ERISA). Neither the Company, its subsidiaries nor any of their
ERISA Affiliates has incurred or reasonably expects to incur any liability under
(i) Title IV of ERISA with respect to termination of, or withdrawal from, any
"employee benefit plan" or (ii) Sections 412, 4971, 4975 or 4980B of the Code.
Each "employee benefit plan" established or maintained by the Company, its
subsidiaries or any of their ERISA Affiliates that is intended to be qualified
under Section 401(a) of the Code is so qualified and nothing has occurred,
whether by action or failure to act, which would cause the loss of such
qualification.

 [May need additional representations and warranties based on due diligence.]

     3.   Purchase of the Stock by the Underwriters.

          (a)  On the basis of the representations and warranties and subject to
the terms and conditions herein set forth, the Company agrees to issue and sell
4,000,000 shares of the Underwritten Stock to the several Underwriters and each
of the Underwriters agrees to purchase from the Company the respective aggregate
number of shares of Underwritten Stock set forth opposite its name in Schedule
I. The price at which such shares of Underwritten Stock shall be sold by the
Company and purchased by the several Underwriters shall be $___ per share. In
making this Agreement, each Underwriter is contracting severally and not
jointly; except as provided in paragraphs (b) and (c) of this Section 3, the
agreement of each Underwriter is to purchase only the respective number of
shares of the Underwritten Stock specified in Schedule I.

          (b)  If for any reason one or more of the Underwriters shall fail or
refuse (otherwise than for a reason sufficient to justify the termination of
this Agreement under the provisions of Section 8 or 9 hereof) to purchase and
pay for the number of shares of the Stock agreed to be purchased by such
Underwriter or Underwriters, the Company shall immediately give notice thereof
to you, and the non-defaulting Underwriters shall have the right within 24 hours
after the receipt by you of such notice to purchase, or procure one or more
other Underwriters to purchase, in such proportions as may be agreed upon
between you and such purchasing Underwriter or Underwriters and upon the terms
herein set forth, all or any part of the shares of the Stock which such
defaulting Underwriter or Underwriters agreed to purchase. If the non-defaulting
Underwriters fail so to make such arrangements with respect to all such shares
and portion, the number of shares of the Stock which each non-defaulting
Underwriter is otherwise obligated to purchase under this Agreement shall be
automatically increased on a pro rata basis to absorb the remaining shares and
portion which the defaulting Underwriter or Underwriters agreed to purchase;
provided, however, that the non-defaulting Underwriters shall not be obligated
to purchase the shares and portion which the defaulting Underwriter or
Underwriters agreed to purchase if the aggregate number of such shares of the
Stock exceeds 10% of the total number of shares of the Stock which all
Underwriters agreed to purchase hereunder. If the total number of shares of the
Stock which the defaulting Underwriter or Underwriters agreed to purchase shall
not be purchased or absorbed in accordance with the two preceding sentences, the
Company shall have the right, within 24 hours next succeeding the 24-hour period
above referred to, to make arrangements with other underwriters or purchasers
satisfactory to you for purchase of such shares and portion on the terms herein
set forth. In any such case, either you or the Company shall have the right to
postpone the Closing Date determined as provided in Section 5 hereof for not
more than seven business days after the date originally fixed as the Closing
Date pursuant to said Section 5 in order that any necessary changes in the
Registration Statement, the Prospectus or any other documents or arrangements
may be made. If neither the non-defaulting Underwriters nor the Company shall
make arrangements within the 24-hour periods stated above for the purchase of
all the shares of the Stock which the defaulting Underwriter or Underwriters
agreed to purchase hereunder, this Agreement shall be terminated without further
act or deed and without any liability on the part of the Company to any non-
defaulting Underwriter and without any liability on the part of any non-
defaulting Underwriter to the Company. Nothing in this paragraph (b), and no
action taken hereunder, shall relieve any defaulting Underwriter from liability
in respect of any default of such Underwriter under this Agreement.

          (c)  On the basis of the representations, warranties and covenants
herein contained, and subject to the terms and conditions herein set forth, the
Company grants an option to the several Underwriters to purchase, severally and
not jointly, up to 600,000 shares in the aggregate of the Option Stock from the
Company at the same price per share as the Underwriters shall pay for the
Underwritten Stock. Said option may be exercised only to cover over-allotments
in the sale of the Underwritten Stock by the Underwriters and may be exercised
in whole or in part at any time (but not more than once) on or before the
thirtieth day after the date of this Agreement upon written or telegraphic
notice by you to the Company setting forth the aggregate number of shares of the
Option Stock as to which the several Underwriters are exercising the option.
Delivery of certificates for the shares of Option Stock, and payment therefor,
shall be made as provided in Section 5 hereof. The number of shares of the

                                      -7-
<PAGE>

Option Stock to be purchased by each Underwriter shall be the same percentage of
the total number of shares of the Option Stock to be purchased by the several
Underwriters as such Underwriter is purchasing of the Underwritten Stock, as
adjusted by you in such manner as you deem advisable to avoid fractional shares.

     4.   Offering by Underwriters.

          (a)  The terms of the initial public offering by the Underwriters of
the Stock to be purchased by them shall be as set forth in the Prospectus. The
Underwriters may from time to time change the public offering price after the
closing of the initial public offering and increase or decrease the concessions
and discounts to dealers as they may determine.

          (b)  The information set forth in the last paragraph on the front
cover page and under "Underwriting" in the Registration Statement, any
Preliminary Prospectus and the Prospectus relating to the Stock filed by the
Company (insofar as such information relates to the Underwriters) constitutes
the only information furnished by the Underwriters to the Company for inclusion
in the Registration Statement, any Preliminary Prospectus, and the Prospectus,
and you on behalf of the respective Underwriters represent and warrant to the
Company that the statements made therein are correct.

     5.   Delivery of and Payment for the Stock.

          (a)  Delivery of certificates for the shares of the Underwritten Stock
and the Option Stock (if the option granted by Section 3(c) hereof shall have
been exercised not later than 7:00 A.M., San Francisco time, on the date two
business days preceding the Closing Date), and payment therefor, shall be made
at the office of Venture Law Group, a Professional Corporation, at 7:00 a.m.,
San Francisco time, on the [fourth]/2/ business day after the date of this
Agreement, or at such time on such other day, not later than seven full business
days after such [fourth] business day, as shall be agreed upon in writing by the
Company and you. The date and hour of such delivery and payment (which may be
postponed as provided in Section 3(b) hereof) are herein called the Closing
Date.

          (b)  If the option granted by Section 3(c) hereof shall be exercised
after 7:00 a.m., San Francisco time, on the date two business days preceding the
Closing Date, delivery of certificates for the shares of Option Stock, and
payment therefor, shall be made at the office of Venture Law Group, a
Professional Corporation, at 7:00 a.m., San Francisco time, on the third
business day after the exercise of such option.

          (c)  Payment for the Stock purchased from the Company shall be made to
the Company or its order by one or more certified or official bank check or
checks in same day funds or, if you so elect, by wire transfer of immediately
available funds to an account specified in writing by the Company. Such payment
shall be made upon delivery of certificates for the Stock to you for the
respective accounts of the several Underwriters against receipt therefor signed
by you. Certificates for the Stock to be delivered to you shall be registered in
such name or names and shall be in such denominations as you may request at
least one business day before the Closing Date, in the case of Underwritten
Stock, and at least one business day prior to the purchase thereof, in the case
of the Option Stock. Such certificates will be made available to the
Underwriters for inspection, checking and packaging at the offices of Lewco
Securities Corporation, 2 Broadway, New York, New York 10004 on the business day
prior to the Closing Date or, in the case of the Option Stock, by 3:00 p.m., New
York time, on the business day preceding the date of purchase. If you so elect,
delivery of the Stock may be made through full fast transfer to the accounts at
The Depository Trust Company designated by you.

     It is understood that you, individually and not on behalf of the
Underwriters, may (but shall not be obligated to) make payment to the Company
for shares to be purchased by any Underwriter whose check shall not have been
received by you on the Closing Date or any later date on which Option Stock is
purchased for the account of such Underwriter.  Any such payment by you shall
not relieve such Underwriter from any of its obligations hereunder.

- ---------------------
/2/ This assumes that the transaction will be priced after the close of market
and that T+4 will apply to the transaction.  If the pricing took place before or
during market hours (which will generally not be the case), the closing would be
three business days after pricing.

     6.   Further Agreements of the Company. The Company covenants and agrees as
follows:

          (a)  The Company will (i) prepare and timely file with the Commission
under Rule 424(b) a Prospectus containing information previously omitted at the
time of effectiveness of the Registration Statement in reliance on Rule 430A and
(ii) not file any amendment to the Registration Statement or supplement to the
Prospectus of which you shall not previously have been advised and furnished
with a copy or to which you shall have reasonably objected in writing or which
is not in compliance with the Securities Act or the rules and regulations of the
Commission.

          (b)  The Company will promptly notify each Underwriter in the event of
(i) the request by the Commission for amendment of the Registration Statement or
for supplement to the Prospectus or for any additional information, (ii) the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration Statement, (iii) the institution or notice of intended institution
of any action or proceeding for that purpose, (iv) the receipt by the Company of
any notification with respect to the suspension of the qualification of the
Stock for sale in any jurisdiction, or (v) the receipt by it of notice of the
initiation or threatening of any proceeding for such purpose. The Company will
make every reasonable effort to prevent the issuance of such a stop order and,
if such an order shall at any time be issued, to obtain the withdrawal thereof
at the earliest possible moment.

          (c)  The Company will (i) on or before the Closing Date, deliver to
you a signed copy of the Registration Statement as originally filed and of each
amendment thereto filed prior to the time the Registration Statement becomes
effective and, promptly upon the filing thereof, a signed copy of each post-
effective amendment, if any, to the Registration Statement (together with, in
each case, all exhibits thereto unless previously furnished to you) and will
also deliver to you, for distribution to the Underwriters, a sufficient number
of additional conformed copies of each of the foregoing (but without exhibits)
so that one copy of each may be distributed to each Underwriter, (ii) as
promptly as possible deliver to you and send to the several Underwriters, at
such office or offices as you may designate, as many copies of the Prospectus as
you may reasonably request, and (iii) thereafter from time to time during the
period in which a prospectus is required by law to be delivered by an
Underwriter or dealer, likewise send to the Underwriters as many additional
copies of the Prospectus and as many copies of any supplement to the Prospectus
and of any amended prospectus, filed by the Company with the Commission, as you
may reasonably request for the purposes contemplated by the Securities Act.

          (d)  If at any time during the period in which a prospectus is
required by law to be delivered by an Underwriter or dealer any event relating
to or affecting the Company, or of which the Company shall be advised in writing
by you, shall occur as a result of which it is necessary, in the opinion of
counsel for the Company or of counsel for the Underwriters, to supplement or
amend the Prospectus in order to make the Prospectus not misleading in the light
of the circumstances existing at the time it is delivered to a purchaser of the
Stock, the Company will forthwith prepare and file with the Commission a
supplement to the Prospectus or an amended prospectus so that the Prospectus as
so supplemented or amended will not contain any untrue statement of a material
fact or omit to state any material fact necessary in order to make the
statements therein, in the light of the circumstances existing at the time such
Prospectus is delivered to such purchaser, not misleading. If, after the initial
public offering of the Stock by the Underwriters and during such period, the
Underwriters shall propose to vary the terms of offering thereof by reason of
changes in general market conditions or otherwise, you will advise the Company
in writing of the proposed variation, and, if in the opinion either of counsel
for the Company or of counsel for the Underwriters such proposed variation
requires that the Prospectus be supplemented or amended, the Company will
forthwith prepare and file with the Commission a supplement to the Prospectus or
an amended prospectus setting forth such variation. The Company authorizes the
Underwriters and all dealers to whom any of the Stock may be sold by the several
Underwriters to use the Prospectus, as from time to time amended or
supplemented, in connection with the sale of the Stock in accordance with the
applicable provisions of the Securities Act and the applicable rules and
regulations thereunder for such period.

          (e)  Prior to the filing thereof with the Commission, the Company will
submit to you, for your information, a copy of any post-effective amendment to
the Registration Statement and any supplement to the Prospectus or any amended
prospectus proposed to be filed.

          (f)  The Company will cooperate, when and as requested by you, in the
qualification of the Stock for offer and sale under the securities or blue sky
laws of such jurisdictions as you may designate and, during

                                      -9-
<PAGE>

the period in which a prospectus is required by law to be delivered by an
Underwriter or dealer, in keeping such qualifications in good standing under
said securities or blue sky laws; provided, however, that the Company shall not
be obligated to file any general consent to service of process or to qualify as
a foreign corporation in any jurisdiction in which it is not so qualified. 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 you may reasonably request for distribution of
the Stock.

          (g)  During a period of five years commencing with the date hereof,
the Company will furnish to you, and to each Underwriter who may so request in
writing, copies of all periodic and special reports furnished to stockholders of
the Company and of all information, documents and reports filed with the
Commission.

          (h)  Not later than the 45th day following the end of the fiscal
quarter first occurring after the first anniversary of the Effective Date, the
Company will make generally available to its security holders an earnings
statement in accordance with Section 11(a) of the Securities Act and Rule 158
thereunder.

          (i)  The Company agrees to pay all costs and expenses incident to the
performance of its obligations under this Agreement, including all costs and
expenses incident to (i) the preparation, printing and filing with the
Commission and the National Association of Securities Dealers, Inc. of the
Registration Statement, any Preliminary Prospectus and the Prospectus, (ii) the
furnishing to the Underwriters of copies of any Preliminary Prospectus and of
the several documents required by paragraph (c) of this Section 6 to be so
furnished, (iii) the printing of this Agreement and related documents delivered
to the Underwriters, (iv) the preparation, printing and filing of all
supplements and amendments to the Prospectus referred to in paragraph (d) of
this Section 6, (v) the furnishing to you and the Underwriters of the reports
and information referred to in paragraph (g) of this Section 6 and (vi) the
printing and issuance of stock certificates, including the transfer agent's
fees.

          (j)  The Company agrees to reimburse you, for the account of the
several Underwriters, for blue sky fees and related disbursements (including
counsel fees and disbursements and cost of printing memoranda for the
Underwriters) paid by or for the account of the Underwriters or their counsel in
qualifying the Stock under state securities or blue sky laws and in the review
of the offering by the NASD.

          (k)  The Company hereby agrees that, without the prior written consent
of Chase Securities Inc. on behalf of the Underwriters, the Company will not,
for a period of 180 days following the commencement of the public offering of
the Stock by the Underwriters, directly or indirectly, (i) sell, offer, contract
to sell, make any short sale, pledge, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase or otherwise transfer or dispose of any shares of Common Stock or any
securities convertible into or exchangeable or exercisable for or any rights to
purchase or acquire Common Stock or (ii) enter into any swap or other agreement
that transfers, in whole or in part, any of the economic consequences or
ownership of Common Stock, whether any such transaction described in clause (i)
or (ii) above is to be settled by delivery of Common Stock or such other
securities, in cash or otherwise. The foregoing sentence shall not apply to (A)
the Stock to be sold to the Underwriters pursuant to this Agreement, (B) shares
of Common Stock issued by the Company upon the exercise of 6,793,436 options
granted under the stock option plans of the Company (the "Option Plans") or upon
the exercise of 343,431 warrants which are outstanding as of the date hereof,
all as described in the Preliminary Prospectus, and (C) options to purchase
Common Stock granted under the Option Plans.

          (l)  If at any time during the [25]-day period after the Registration
Statement becomes effective any rumor, publication or event relating to or
affecting the Company shall occur as a result of which in your opinion the
market price for the Stock has been or is likely to be materially affected
(regardless of whether such rumor, publication or event necessitates a
supplement to or amendment of the Prospectus), the Company will, after written
notice from you advising the Company to the effect set forth above, forthwith
prepare, consult with you concerning the substance of, and disseminate a press
release or other public statement, reasonably satisfactory to you, responding to
or commenting on such rumor, publication or event.

          (m)  The Company is familiar with the Investment Company Act of 1940,
as amended, and has in the past conducted its affairs, and will in the future
conduct its affairs, in such a manner to ensure that the Company was not and
will not be an "investment company" or a company "controlled" by an "investment

                                      -10-
<PAGE>

company" within the meaning of the Investment Company Act of 1940, as amended,
and the rules and regulations thereunder.


     7.   Indemnification and Contribution.


          (a)  The Company agrees to indemnify and hold harmless each
Underwriter and each person (including each partner or officer thereof) who
controls any Underwriter within the meaning of Section 15 of the Securities Act
from and against any and all losses, claims, damages or liabilities, joint or
several, to which such indemnified parties or any of them may become subject
under the Securities Act, the Exchange Act, or the common law or otherwise, and
the Company agrees to reimburse each such Underwriter and controlling person for
any legal or other expenses (including, except as otherwise hereinafter
provided, reasonable fees and disbursements of counsel) incurred by the
respective indemnified parties in connection with defending against any such
losses, claims, damages or liabilities or in connection with any investigation
or inquiry of, or other proceeding which may be brought against, the respective
indemnified parties, in each case arising out of or based upon (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement (including the Prospectus as part thereof and any Rule
462(b) registration statement) or any post-effective amendment thereto
(including any Rule 462(b) registration statement), or 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 (ii) any untrue
statement or alleged untrue statement of a material fact contained in any
Preliminary Prospectus or the Prospectus (as amended or as supplemented if the
Company shall have filed with the Commission any amendment thereof or supplement
thereto) or the omission or alleged omission to state therein a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided, however,
that (1) the indemnity agreements of the Company contained in this paragraph (a)
shall not apply to any such losses, claims, damages, liabilities or expenses if
such statement or omission was made in reliance upon and in conformity with
information furnished as herein stated or otherwise furnished in writing to the
Company by or on behalf of any Underwriter for use in any Preliminary Prospectus
or the Registration Statement or the Prospectus or any such amendment thereof or
supplement thereto and (2) the indemnity agreement contained in this paragraph
(a) with respect to any Preliminary Prospectus shall not inure to the benefit of
any Underwriter from whom the person asserting any such losses, claims, damages,
liabilities or expenses purchased the Stock which is the subject thereof (or to
the benefit of any person controlling such Underwriter) if at or prior to the
written confirmation of the sale of such Stock a copy of the Prospectus (or the
Prospectus as amended or supplemented) was not sent or delivered to such person
and the untrue statement or omission of a material fact contained in such
Preliminary Prospectus was corrected in the Prospectus (or the Prospectus as
amended or supplemented) unless the failure is the result of noncompliance by
the Company with paragraph (c) of Section 6 hereof. The indemnity agreements of
the Company contained in this paragraph (a) and the representations and
warranties of the Company contained in Section 2 hereof shall remain operative
and in full force and effect regardless of any investigation made by or on
behalf of any indemnified party and shall survive the delivery of and payment
for the Stock.

          (b)  Each Underwriter severally agrees to indemnify and hold harmless
the Company, each of its officers who signs the Registration Statement on his
own behalf or pursuant to a power of attorney, each of its directors, each other
Underwriter and each person (including each partner or officer thereof) who
controls the Company or any such other Underwriter within the meaning of Section
15 of the Securities Act, from and against any and all losses, claims, damages
or liabilities, joint or several, to which such indemnified parties or any of
them may become subject under the Securities Act, the Exchange Act or the common
law or otherwise and to reimburse each of them for any legal or other expenses
(including, except as otherwise hereinafter provided, reasonable fees and
disbursements of counsel) incurred by the respective indemnified parties in
connection with defending against any such losses, claims, damages or
liabilities or in connection with any investigation or inquiry of, or other
proceeding which may be brought against, the respective indemnified parties, in
each case arising out of or based upon (i) any untrue statement or alleged
untrue statement of a material fact contained in the Registration Statement
(including the Prospectus as part thereof and any Rule 462(b) registration
statement) or any post-effective amendment thereto (including any Rule 462(b)
registration statement) or 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 (ii) any untrue statement or alleged untrue statement
of a material fact contained in the Prospectus (as amended or as supplemented if
the Company shall have filed with the Commission any amendment thereof or
supplement thereto) or the omission or alleged omission to state therein a
material fact necessary in order to make the statements therein, in the light of
the circumstances under which they were made, not misleading, if such statement
or omission was made in reliance upon and in conformity with information
furnished as herein stated or otherwise

                                      -11-
<PAGE>

furnished in writing to the Company by or on behalf of such indemnifying
Underwriter for use in the Registration Statement or the Prospectus or any such
amendment thereof or supplement thereto. The indemnity agreement of each
Underwriter contained in this paragraph (b) shall remain operative and in full
force and effect regardless of any investigation made by or on behalf of any
indemnified party and shall survive the delivery of and payment for the Stock.

          (c)  Each party indemnified under the provision of paragraphs (a) and
(b) of this Section 7 agrees that, upon the service of a summons or other
initial legal process upon it in any action or suit instituted against it or
upon its receipt of written notification of the commencement of any
investigation or inquiry of, or proceeding against, it in respect of which
indemnity may be sought on account of any indemnity agreement contained in such
paragraphs, it will promptly give written notice (herein called the Notice) of
such service or notification to the party or parties from whom indemnification
may be sought hereunder. No indemnification provided for in such paragraphs
shall be available to any party who shall fail so to give the Notice if the
party to whom such Notice was not given was unaware of the action, suit,
investigation, inquiry or proceeding to which the Notice would have related and
was prejudiced by the failure to give the Notice, but the omission so to notify
such indemnifying party or parties of any such service or notification shall not
relieve such 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 such indemnity agreement. Any indemnifying party shall be entitled at its own
expense to participate in the defense of any action, suit or proceeding against,
or investigation or inquiry of, an indemnified party. Any indemnifying party
shall be entitled, if it so elects within a reasonable time after receipt of the
Notice by giving written notice (herein called the Notice of Defense) to the
indemnified party, to assume (alone or in conjunction with any other
indemnifying party or parties) the entire defense of such action, suit,
investigation, inquiry or proceeding, in which event such defense shall be
conducted, at the expense of the indemnifying party or parties, by counsel
chosen by such indemnifying party or parties and reasonably satisfactory to the
indemnified party or parties; provided, however, that (i) if the indemnified
party or parties reasonably determine that there may be a conflict between the
positions of the indemnifying party or parties and of the indemnified party or
parties in conducting the defense of such action, suit, investigation, inquiry
or proceeding or that there may be legal defenses available to such indemnified
party or parties different from or in addition to those available to the
indemnifying party or parties, then counsel for the indemnified party or parties
shall be entitled to conduct the defense to the extent reasonably determined by
such counsel to be necessary to protect the interests of the indemnified party
or parties and (ii) in any event, the indemnified party or parties shall be
entitled to have counsel chosen by such indemnified party or parties participate
in, but not conduct, the defense. If, within a reasonable time after receipt of
the Notice, an indemnifying party gives a Notice of Defense and the counsel
chosen by the indemnifying party or parties is reasonably satisfactory to the
indemnified party or parties, the indemnifying party or parties will not be
liable under paragraphs (a) through (c) of this Section 7 for any legal or other
expenses subsequently incurred by the indemnified party or parties in connection
with the defense of the action, suit, investigation, inquiry or proceeding,
except that (A) the indemnifying party or parties shall bear the legal and other
expenses incurred in connection with the conduct of the defense as referred to
in clause (i) of the proviso to the preceding sentence and (B) the indemnifying
party or parties shall bear such other expenses as it or they have authorized to
be incurred by the indemnified party or parties. If, within a reasonable time
after receipt of the Notice, no Notice of Defense has been given, the
indemnifying party or parties shall be responsible for any legal or other
expenses incurred by the indemnified party or parties in connection with the
defense of the action, suit, investigation, inquiry or proceeding.

          (d)  If the indemnification provided for in this Section 7 is
unavailable or insufficient to hold harmless an indemnified party under
paragraph (a) or (b) of this Section 7, then each indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of the losses, claims, damages or
liabilities referred to in paragraph (a) or (b) of this Section 7 (i) in such
proportion as is appropriate to reflect the relative benefits received by each
indemnifying party from the offering of the Stock or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of each indemnifying party in
connection with the statements or omissions that resulted in such losses,
claims, damages or liabilities, or actions in respect thereof, as well as any
other relevant equitable considerations. The relative benefits received by the
Company and the Underwriters shall be deemed to be in the same respective
proportions as the total net proceeds from the offering of the Stock received by
the Company and the total underwriting discount received by the Underwriters, as
set forth in the table on the cover page of the Prospectus, bear to the
aggregate public offering price of the Stock. 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

                                      -12-
<PAGE>

to state a material fact relates to information supplied by each indemnifying
party and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such untrue statement or omission.

     The parties agree that it would not be just and equitable if contributions
pursuant to this paragraph (d) were to be 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 into account the equitable
considerations referred to in the first sentence of this paragraph (d).  The
amount paid by an indemnified party as a result of the losses, claims, damages
or liabilities, or actions in respect thereof, referred to in the first sentence
of this paragraph (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigation,
preparing to defend or defending against any action or claim which is the
subject of this paragraph (d). Notwithstanding the provisions of this paragraph
(d), no Underwriter shall be required to contribute any amount in excess of the
underwriting discount applicable to the Stock purchased by such Underwriter. No
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.  The Underwriters'
obligations in this paragraph (d) to contribute are several in proportion to
their respective underwriting obligations and not joint.

     Each party entitled to contribution agrees that upon the service of a
summons or other initial legal process upon it in any action instituted against
it in respect of which contribution may be sought, it will promptly give written
notice of such service to the party or parties from whom contribution may be
sought, but the omission so to notify such party or parties of any such service
shall not relieve the party from whom contribution may be sought from any
obligation it may have hereunder or otherwise (except as specifically provided
in paragraph (c) of this Section 7).

          (e)  The Company will not, without the prior written consent of each
Underwriter, settle or compromise or consent to the entry of any judgment in any
pending or threatened claim, action, suit or proceeding in respect of which
indemnification may be sought hereunder (whether or not such Underwriter or any
person who controls such Underwriter within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act is a party to such claim,
action, suit or proceeding) unless such settlement, compromise or consent
includes an unconditional release of such Underwriter and each such controlling
person from all liability arising out of such claim, action, suit or proceeding.

     8.   Termination.  This Agreement may be terminated by you at any time
prior to the Closing Date by giving written notice to the Company if after the
date of this Agreement trading in the Common Stock shall have been suspended, or
if there shall have occurred (i) the engagement in hostilities or an escalation
of major hostilities by the United States or the declaration of war or a
national emergency by the United States on or after the date hereof, (ii) any
outbreak of hostilities or other national or international calamity or crisis or
change in economic or political conditions if the effect of such outbreak,
calamity, crisis or change in economic or political conditions in the financial
markets of the United States would, in the Underwriters' reasonable judgment,
make the offering or delivery of the Stock impracticable, (iii) suspension of
trading in securities generally or a material adverse decline in value of
securities generally on the New York Stock Exchange, the American Stock
Exchange, The Nasdaq Stock Market, or limitations on prices (other than
limitations on hours or numbers of days of trading) for securities on either
such exchange or system, (iv) the enactment, publication, decree or other
promulgation of any federal or state statute, regulation, rule or order of, or
commencement of any proceeding or investigation by, any court, legislative body,
agency or other governmental authority which in the Underwriters' reasonable
opinion materially and adversely affects or will materially or adversely affect
the business or operations of the Company, (v) declaration of a banking
moratorium by either federal or New York State authorities or (vi) the taking of
any action by any federal, state or local government or agency in respect of its
monetary or fiscal affairs which in the Underwriters' reasonable opinion has a
material adverse effect on the securities markets in the United States. If this
Agreement shall be terminated pursuant to this Section 8, there shall be no
liability of the Company to the Underwriters and no liability of the
Underwriters to the Company; provided, however, that in the event of any such
termination the Company agrees to indemnify and hold harmless the Underwriters
from all costs or expenses incident to the performance of the obligations of the
Company under this Agreement, including all costs and expenses referred to in
paragraphs (i) and (j) of Section 6 hereof.

          9.   Conditions of Underwriters' Obligations.  The obligations of the
several Underwriters to purchase and pay for the Stock shall be subject to the
performance by the Company of all its obligations to be

                                      -13-
<PAGE>

performed hereunder at or prior to the Closing Date or any later date on which

further conditions:

          (a)  The Registration Statement shall have become effective; and no
stop order suspending the effectiveness thereof shall have been issued and no
proceedings therefor shall be pending or threatened by the Commission.

          (b)  The legality and sufficiency of the sale of the Stock hereunder
and the validity and form of the certificates representing the Stock, all
corporate proceedings and other legal matters incident to the foregoing, and the
form of the Registration Statement and of the Prospectus (except as to the
financial statements contained therein), shall have been approved at or prior to
the Closing Date by Wilson Sonsini Goodrich & Rosati, counsel for the
Underwriters.

          (c)  You shall have received from Venture Law Group, counsel for the
Company, and from __________, patent counsel for the Company, opinions,
addressed to the Underwriters and dated the Closing Date, covering the matters
set forth in Annex A and Annex B hereto, respectively, and if Option Stock is
purchased at any date after the Closing Date, additional opinions from each such
counsel, addressed to the Underwriters and dated such later date, confirming
that the statements expressed as of the Closing Date in such opinions remain
valid as of such later date.

          (d)  You shall be satisfied that (i) as of the Effective Date, the
statements made in the Registration Statement and the Prospectus were true and
correct and neither the Registration Statement nor the Prospectus omitted to
state any material fact required to be stated therein or necessary in order to
make the statements therein, respectively, not misleading, (ii) since the
Effective Date, no event has occurred which should have been set forth in a
supplement or amendment to the Prospectus which has not been set forth in such a
supplement or amendment, (iii) since the respective dates as of which
information is given in the Registration Statement in the form in which it
originally became effective and the Prospectus contained therein, there has not
been any material adverse change or any development involving a prospective
material adverse change in or affecting the business, properties, financial
condition or results of operations of the Company and its subsidiaries, taken as
a whole, whether or not arising from transactions in the ordinary course of
business, and, since such dates, except in the ordinary course of business,
neither the Company nor any of its subsidiaries has entered into any material
transaction not referred to in the Registration Statement in the form in which
it originally became effective and the Prospectus contained therein, (iv)
neither the Company nor any of its subsidiaries has any material contingent
obligations which are not disclosed in the Registration Statement and the
Prospectus, (v) there are not any pending or known threatened legal proceedings

there are not any franchises, contracts, leases or other documents which are
required to be filed as exhibits to the Registration Statement which have not

any later date on which Option Stock is to be purchased, as the case may be, and
(viii) there has not been any material change in the market for securities in
general or in political, financial or economic conditions from those reasonably
foreseeable as to render it impracticable in your reasonable judgment to make a
public offering of the Stock, or a material adverse change in market levels for
securities in general (or those of companies in particular) or financial or
economic conditions which render it inadvisable to proceed.

          (e)  You shall have received on the Closing Date and on any later date
on which Option Stock is purchased a certificate, dated the Closing Date or such
later date, as the case may be, and signed by the President and the Chief
Financial Officer of the Company, stating that the respective signers of said

which it originally became effective and the Prospectus contained therein and

clauses (i) through (vii) of paragraph (d) of this Section 9 are true and
correct.

          (f)  You shall have received from KPMG LLP a letter or letters,
addressed to the Underwriters and dated the Closing Date and any later date on
which Option Stock is purchased, confirming that they are independent public
accountants with respect to the Company within the meaning of the Securities Act
and the applicable published rules and regulations thereunder and based upon the
procedures described in their letter delivered to you concurrently with the
execution of this Agreement (herein called the Original Letter), but carried out

is purchased (i) confirming, to the extent true, that the statements and
conclusions set forth in the Original Letter are accurate as of the Closing Date
or such later date, as the case may be, and (ii) setting forth any revisions and
additions to the statements and conclusions set forth in the Original Letter
which are necessary to reflect any changes in the facts described in the
Original Letter since the date of the Original Letter or to reflect the
availability of more recent financial statements, data or information. The
letters shall not disclose any change, or any development involving a
prospective change, in or affecting the business or properties of the Company or
any of its subsidiaries which, in your sole judgment, makes it impractical or
inadvisable to proceed with the public offering of the Stock or the purchase of
the Option Stock as contemplated by the Prospectus.

          (g)  You shall have received from KPMG LLP a letter stating that their
review of the Company's system of internal accounting controls, to the extent
they deemed necessary in establishing the scope of their examination of the
Company's financial statements as at December 31, 1999, did not disclose any
weakness in internal controls that they considered to be material weaknesses.

          (h)  You shall have been furnished evidence in usual written or
telegraphic form from the appropriate authorities of the several jurisdictions,
or other evidence satisfactory to you, of the qualification referred to in
paragraph (f) of Section 6 hereof.

          (j)  On or prior to the Closing Date, you shall have received from all
directors, officers, and beneficial holders of the outstanding Common Stock
agreements, in form reasonably satisfactory to Chase Securities Inc., stating
that without the prior written consent of Chase Securities Inc. on behalf of the
Underwriters, such person or entity will not, for a period of 180 days following
the commencement of the public offering of the Stock by the Underwriters,
directly or indirectly, (i) sell, offer, contract to sell, make any short sale,
pledge, sell any option or contract to purchase, purchase any option or contract
to sell, grant any option, right or warrant to purchase or otherwise transfer or
dispose of any shares of Common Stock or any securities convertible into or
exchangeable or exercisable for or any rights to purchase or acquire Common
Stock or (ii) enter into any swap or other agreement that transfers, in whole or
in part, any of the economic consequences or ownership of Common Stock, whether
any such transaction described in clause (i) or (ii) above is to be settled by
delivery of Common Stock or such other securities, in cash or otherwise.


     All the agreements, opinions, certificates and letters mentioned above or
elsewhere in this Agreement shall be deemed to be in compliance with the
provisions hereof only if Wilson Sonsini Goodrich & Rosati, counsel for the
Underwriters, shall be satisfied that they comply in form and scope.

     In case any of the conditions specified in this Section 9 shall not be
fulfilled, this Agreement may be terminated by you by giving notice to the
Company.  Any such termination shall be without liability of the Company to the
Underwriters and without liability of the Underwriters to the Company; provided,
however, that (i) in the event of such termination, the Company agrees to
indemnify and hold harmless the Underwriters from all costs or expenses incident
to the performance of the obligations of the Company under this Agreement,
including all costs and expenses referred to in paragraphs (i) and (j) of
Section 6 hereof, and (ii) if this Agreement is terminated by you because of any
refusal, inability or failure on the part of the Company to perform any
agreement herein, to fulfill any of the conditions herein, or to comply with any
provision hereof other than by reason of a default by any of the Underwriters,
the Company will reimburse the Underwriters severally upon demand for all out-
of-pocket expenses (including reasonable fees and disbursements of counsel) that
shall have been incurred by them in connection with the transactions
contemplated hereby.

     10.  Conditions of the Obligation of the Company. The obligation of the
Company to deliver the Stock shall be subject to the conditions that (a) the
Registration Statement shall have become effective and (b) no stop order
suspending the effectiveness thereof shall be in effect and no proceedings
therefor shall be pending or threatened by the Commission.

     In case either of the conditions specified in this Section 10 shall not be
fulfilled, this Agreement may be terminated by the Company by giving notice to
you.  Any such termination shall be without liability of the Company to the
Underwriters and without liability of the Underwriters to the Company; provided,
however, that in the event of any such termination the Company agrees to
indemnify and hold harmless the Underwriters from all

                                      -15-
<PAGE>

costs or expenses incident to the performance of the obligations of the Company
under this Agreement, including all costs and expenses referred to in paragraphs
(i) and (j) of Section 6 hereof.

     11.  Reimbursement of Certain Expenses.  In addition to its other

other expenses incurred in connection with investigating or defending any claim,
action, investigation, inquiry or other proceeding arising out of or based upon
any statement or omission, or any alleged statement or omission, described in
paragraph (a) of Section 7 of this Agreement, notwithstanding the absence of a
judicial determination as to the propriety and enforceability of the obligations
under this Section 11 and the possibility that such payments might later be held
to be improper; provided, however, that (i) to the extent any such payment is
                --------  -------
ultimately held to be improper, the persons receiving such payments shall
promptly refund them and (ii) such persons shall provide to the Company, upon
request, reasonable assurances of their ability to effect any refund, when and
if due.

     12.  Persons Entitled to Benefit of Agreement.  This Agreement shall inure
to the benefit of the Company and the several Underwriters and, with respect to
the provisions of Section 7 hereof, the several parties (in addition to the
Company and the several Underwriters) indemnified under the provisions of said
Section 7, and their respective personal representatives, successors and
assigns. Nothing in this Agreement is intended or shall be construed to give to
any other person, firm or corporation any legal or equitable remedy or claim
under or in respect of this Agreement or any provision herein contained. The
term "successors and assigns" as herein used shall not include any purchaser, as
such purchaser, of any of the Stock from any of the several Underwriters.

     13.  Notices.  Except as otherwise provided herein, all communications
hereunder shall be in writing or by telegraph and, if to the Underwriters, shall
be mailed, telegraphed or delivered to Chase Securities Inc., One Bush Street,
San Francisco, California 94104; and if to the Company, shall be mailed,

     14.  Miscellaneous.  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 their respective directors or officers, and (c) delivery and
payment for the Stock under this Agreement; provided, however, that if this
                                            --------  -------
Agreement is terminated prior to the Closing Date, the provisions of paragraph
(k) of Section 6 hereof shall be of no further force or effect.

     This Agreement may be executed in two or more counterparts, each of which
shall be deemed an original, but all of which together shall constitute one and
the same instrument.

     This Agreement shall be governed by, and construed in accordance with, the
laws of the State of California.

     Please sign and return to the Company the enclosed duplicates of this
letter, whereupon this letter will become a binding agreement between the
Company and the several Underwriters in accordance with its terms.

                                    ANNEX A

           Matters to be Covered in the Opinion of Venture Law Group
                            Counsel for the Company

          (i)      each of the Company and its U.K. and Germany subsidiaries
(the "Subsidiaries") has been duly incorporated and is validly existing as a
corporation in good standing under the laws of the jurisdiction of its
incorporation, is duly qualified as a foreign corporation and in good standing
in each state of the United States of America in which its ownership or leasing
of property requires such qualification (except where the failure to be so
qualified would not have a material adverse effect on the business, properties,
financial condition or results of operations of the Company and its
subsidiaries, taken as a whole), and has full corporate power and authority to
own or lease its properties and conduct its business as described in the
Registration Statement; all the issued and outstanding capital stock of each of
the Subsidiaries of the Company has been duly authorized and validly issued and
is fully paid and nonassessable, and is owned by the Company free and clear of
all liens, encumbrances and security interests, and to the counsel's knowledge,
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 such Subsidiaries are outstanding;

          (ii)     the authorized capital stock of the Company consists of
                                                                           -----
shares of Preferred Stock and      shares of Common Stock, $     par value;
                             ------                         -----
proper corporate proceedings have been taken validly to authorize such
authorized capital stock; all of the shares of Stock, when issued and delivered
to and paid for by the Underwriters as provided in the Underwriting Agreement,
will have been duly and validly issued and be fully paid and nonassessable; and
no preemptive rights of, or rights of refusal in favor of, stockholders exist
with respect to the Stock, or the issue and sale thereof, pursuant to the
Certificate of Incorporation or Bylaws of the Company and, to the knowledge of
such counsel, there are no contractual preemptive rights that have not been
waived, rights of first refusal or rights of co-sale which exist with respect to
the issue and sale of the Stock;

                          CROSSWORLDS SOFTWARE, INC.
          The undersigned, Alfred J. Amoroso and Stacey Giamalis, hereby certify
that:

          1.  They are the duly elected and acting President and Secretary,
respectively, of CrossWorlds Software, Inc., a Delaware corporation.

          2.  The Certificate of Incorporation of this corporation was
originally filed with the Secretary of State of Delaware on March 8, 1996  under
the name of  CrossRoads Software, Inc.

          3.  The Certificate of Incorporation of this corporation shall be
amended and restated to read in full as follows:

                                  "ARTICLE I

          The name of this corporation is CrossWorlds Software, Inc. (the
"CORPORATION").

                                  ARTICLE II

          The address of the Corporation's registered office in the State of
Delaware is 1209 Orange Street, Wilmington, County of New Castle.  The name of
its registered agent at such address is The Corporation Trust Company.

                                  ARTICLE III

          The purpose of the Corporation is to engage in any lawful act or
activity for which corporations may be organized under the General Corporation
Law of Delaware.

                                  ARTICLE IV

          The Corporation is authorized to issue one class of stock to be
designated "Common Stock."  The total number of shares which the Corporation is
authorized to issue is One Hundred Fifty Million (150,000,000) shares, each with
a par value of $0.001 per share.

                                   ARTICLE V

          The number of directors of the Corporation shall be fixed from time to
time by a bylaw or amendment thereof duly adopted by the Board of Directors;
provided that the Corporation shall not increase the size of the Corporation's
Board of Directors to more than nine (9) without first obtaining the affirmative
vote of a majority of the voting power of all of the then-outstanding shares of
the voting stock of the Corporation entitled to vote.
<PAGE>

                                  ARTICLE VI

          All directors shall be elected at each annual meeting of stockholders
to hold office until the next annual meeting.  Each director shall serve until
his or her successor is duly elected and qualified or until his or her death,
resignation, or removal.  No decrease in the number of directors constituting
the Board of Directors shall shorten the term of any incumbent director.

          Any vacancies on the Board of Directors resulting from death,
resignation, disqualification, removal, or other causes shall be filled by
either (i) the affirmative vote of the holders of a majority of the voting power
of the then-outstanding shares of voting stock of the corporation entitled to
vote generally in the election of directors (the "Voting Stock") voting together
as a single class; or (ii) by the affirmative vote of a majority of the
remaining directors then in office, even though less than a quorum of the Board
of Directors.  Newly created directorships resulting from any increase in the
number of directors shall, unless the Board of Directors determines by
resolution that any such newly created directorship shall be filled by the
stockholders, be filled only by the affirmative vote of the directors then in
office, even though less than a quorum of the Board of Directors, or by a sole
remaining director.  Any director elected in accordance with the preceding
sentence shall hold office for the remainder of the full term of the class of
directors in which the new directorship was created or the vacancy occurred and
until such director's successor shall have been elected and qualified.  Any
director, or the entire Board of Directors, may be removed from office, with or
without cause, by the holders of a majority of the Voting Stock.

                                  ARTICLE VII

          In the election of directors, each holder of shares of any class or
series of capital stock of the Corporation shall be entitled to one vote for
each share held.  No stockholder will be permitted to cumulate votes at any
election of directors.

                                 ARTICLE VIII

          No action shall be taken by the stockholders of the Corporation other
than at an annual or special meeting of the stockholders, upon due notice and in
accordance with the provisions of the Bylaws of the Corporation (the "Bylaws"),
and no action shall be taken by the stockholders by written consent.

                                  ARTICLE IX

          The Corporation reserves the right to amend, alter, change or repeal
any provision contained in this Certificate of Incorporation, in the manner now
or hereafter prescribed by statute, and all rights conferred upon stockholders
herein are granted subject to this reservation.

                                   ARTICLE X

          (A) The Bylaws may be altered or amended or new Bylaws adopted by the
affirmative vote of a majority of the voting power of all of the then-
outstanding shares of the voting stock of the Corporation entitled to vote.  The
Board of Directors of the Corporation is expressly

                                      -2-
<PAGE>

authorized to adopt, amend or repeal Bylaws, other than Sections 2.3, 2.4, 2.5
of the Bylaws, and the Board of Directors of the Corporation is expressly
authorized to adopt, amend or repeal Section 3.2 of the Bylaws to the extent it
can do so in accordance with Article V hereof.

          (B) The directors of the Corporation need not be elected by written
ballot unless the Bylaws so provide.

          (C) Advance notice of stockholder nominations for the election of
directors or of business to be brought by the stockholders before any meeting of
the stockholders of the corporation shall be given in the manner provided in the
Bylaws.

                                  ARTICLE XI

          Meetings of stockholders may be held within or without the State of
Delaware, as the Bylaws may provide.  The books of the Corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the bylaws of the Corporation.

                                  ARTICLE XII

          The Corporation shall have perpetual existence.

                                 ARTICLE XIII

          (A) To the fullest extent permitted by the General Corporation Law of
Delaware, as the same may be amended from time to time, a director of the
Corporation shall not be personally liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director.
If the General Corporation Law of Delaware is hereafter amended to authorize,
with or without the approval of a corporation's stockholders, further reductions
in the liability of a corporation's directors for breach of fiduciary duty, then
a director of the Corporation shall not be liable for any such breach to the
fullest extent permitted by the General Corporation Law of Delaware, as so
amended.

          (B) Any repeal or modification of the foregoing provisions of this
Article XIII shall not adversely affect any right or protection of a director of
the Corporation with respect to any acts or omissions of such director occurring
prior to such repeal or modification.

                                  ARTICLE XIV

          (A) To the fullest extent permitted by applicable law, the Corporation
is also authorized to provide indemnification of (and advancement of expenses
to) such agents (and any other persons to which Delaware law permits the
Corporation to provide indemnification) through Bylaw provisions, agreements
with such agents or other persons, vote of stockholders or disinterested
directors or otherwise, in excess of the indemnification and advancement
otherwise permitted by Section 145 of the General Corporation Law of Delaware,
subject only to limits created by applicable Delaware law (statutory or non-
statutory), with respect to actions for breach of duty to a corporation, its
stockholders, and others.

                                      -3-
<PAGE>

          (B) Any repeal or modification of any of the foregoing provisions of
this Article XIV shall not adversely affect any right or protection of a
director, officer, agent or other person existing at the time of, or increase
the liability of any director of the Corporation with respect to any acts or
omissions of such director, officer or agent occurring prior to such repeal or
modification."

     2.5  ADVANCE NOTICE OF STOCKHOLDER NOMINEES AND OTHER STOCKHOLDER
          ------------------------------------------------------------
PROPOSALS.
- ---------

          Only persons who are nominated in accordance with the procedures set
forth in this Section 2.5 shall be eligible for election as directors.
Nominations of persons for election to the Board of Directors of the Corporation
may be made at a meeting of stockholders by or at the direction of the Board of
Directors or by any stockholder of the Corporation entitled to vote for the
election of directors at the meeting who complies with the notice procedures set
forth in this Section 2.5.  Such nominations, other than those made by or at the
direction of the Board of Directors, shall be made pursuant to timely notice in
writing to the secretary of the Corporation. Stockholders may bring other
business before the annual meeting, provided that timely notice is provided to
the secretary of the Corporation in accordance with this section, and provided
further than such business is a proper matter for stockholder action under the
General Corporation Law of Delaware.  To be timely, a stockholder's notice shall
be delivered to or mailed and received at the principal executive offices of the
Corporation not less than 90 days nor more than 120 days prior to the
anniversary date of the prior year's meeting; provided, however, that in the
event that (i) the date of the annual meeting is more than 30 days prior to or
more than 60 days after such anniversary date, and (ii) less than 60 days notice
or prior public disclosure of the date of the meeting is given or made to
stockholders, then notice by the stockholder to be timely must be so received
not  later than the close of business on the 10/th/ day following the day on
which such notice of the date of the meeting was mailed or such public
disclosure was made.

          Such stockholder's notice shall set forth (a) as to each person whom
the stockholder proposes to nominate for election or re-election as a director,
(i) the name, age, business address and residence address of such

                                      -2-
<PAGE>

person, (ii) the principal occupation or employment of such person, (iii) the
class and number of shares of the Corporation which are beneficially owned by
such person and (iv) any other information relating to such person that is
required to be disclosed in solicitations of proxies for election of directors,
or is otherwise required, in each case pursuant to Regulation 14A under the
Securities Exchange Act of 1934 (including, without limitation, such person's
written consent to being named in the proxy statement as a nominee and to
serving as a director if elected); (b) as to any other business that the
stockholder proposes to bring before the meeting, a brief description of such
business, the reasons for conducting such business at the meeting and any
material interest in such business of such stockholder and the beneficial owner,
if any, on whose behalf the proposal is made; and (c) as to the stockholder
giving the notice and the beneficial owner, if any, on whose behalf the proposal
is made (i) the name and address of the stockholder, as they appear on the
Corporation's books, and of such beneficial owner and (ii) the class and number
of shares of the Corporation which are owned of record by such stockholder and
beneficially by such beneficial owner.

          At the request of the Board of Directors any person nominated by the
Board of Directors for election as a director shall furnish to the secretary of
the Corporation that information required to be set forth in a stockholder's
notice of nomination which pertains to the nominee.  No person shall be eligible
for election as a director of the Corporation unless nominated in accordance
with the procedures set forth in this Section 2.5.  The chairman of the meeting
shall, if the facts warrant, determine and declare to the meeting that a
nomination was not made in accordance with the procedures prescribed by the
Bylaws, and if he or she should so determine, he or she shall so declare to the
meeting and the defective nomination shall be disregarded.

     2.6  QUORUM.
          ------

          The holders of a majority of the stock issued and outstanding and
entitled to vote thereat, present in person or represented by proxy, shall
constitute a quorum at all meetings of the stockholders for the transaction of
business except as otherwise provided by statute or by the Certificate of
Incorporation.  If, however, such quorum is not present or represented at any
meeting of the stockholders, then either (a) the chairman of the meeting or (b)
the stockholders entitled to vote thereat, present in person or represented by
proxy, shall have power to adjourn the meeting from time to time, without notice
other than announcement at the meeting, until a quorum is present or
represented.  At such adjourned meeting at which a quorum is present or
represented, any business may be transacted that might have been transacted at
the meeting as originally noticed.

     2.7  ADJOURNED MEETING; NOTICE.
          -------------------------

          When a meeting is adjourned to another time or place, unless these
Bylaws otherwise require, notice need not be given of the adjourned meeting if
the time and place thereof are announced at the meeting at which the adjournment
is taken.  At the adjourned meeting the Corporation may transact any business
that might have been transacted at the original meeting.  If the adjournment is
for more than 30 days, or if after the adjournment a new record date is fixed
for the adjourned meeting, a notice of the adjourned meeting shall be given to
each stockholder of record entitled to vote at the meeting.

     2.8  CONDUCT OF BUSINESS.
          -------------------

          The chairman of any meeting of stockholders shall determine the order
of business and the procedure at the meeting, including the manner of voting and
the conduct of business.

     2.9  VOTING.
          ------

          (a) The stockholders entitled to vote at any meeting of stockholders
shall be determined in accordance with the provisions of Section 2.11 of these
Bylaws, subject to the provisions of Sections 217 and 218 of the General
Corporation Law of Delaware (relating to voting rights of fiduciaries, pledgors
and joint owners of stock and to voting trusts and other voting agreements).

                                      -3-
<PAGE>

          (b) Except as may be otherwise provided in the Certificate of
Incorporation, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder.

     2.10 WAIVER OF NOTICE.
          ----------------

          Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the Certificate of Incorporation or
these Bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice.  Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened.  Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the Certificate of Incorporation or these Bylaws.

     2.11 RECORD DATE FOR STOCKHOLDER NOTICE; VOTING.
          ------------------------------------------

          In order that the Corporation may determine the stockholders entitled
to notice of or to vote at any meeting of stockholders or any adjournment
thereof or entitled to receive payment of any dividend or other distribution or
allotment of any rights, or entitled to exercise any rights in respect of any
change, conversion or exchange of stock or for the purpose of any other lawful
action, the Board of Directors may fix, in advance, a record date, which shall
not be more than 60 nor less than 10 days before the date of such meeting, nor
more than 60 days prior to any other action.  If the Board of Directors does not
so fix a record date:

          (a) The record date for determining stockholders entitled to notice of
or to vote at a meeting of stockholders shall be at the close of business on the
day next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next preceding the day on which the meeting is
held.

          (b) The record date for determining stockholders for any other purpose
shall be at the close of business on the day on which the Board of Directors
adopts the resolution relating thereto.

          A determination of stockholders of record entitled to notice of or to
vote at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

     2.12 PROXIES.
          -------

          Each stockholder entitled to vote at a meeting of stockholders may
authorize another person or persons to act for such stockholder by a written
proxy, signed by the stockholder and filed with the secretary of the
Corporation, but no such proxy shall be voted or acted upon after three years
from its date, unless the proxy provides for a longer period.  A proxy shall be
deemed signed if the stockholder's name is placed on the proxy (whether by
manual signature, typewriting, telegraphic transmission or otherwise) by the
stockholder or the stockholder's attorney-in-fact.  The revocability of a proxy
that states on its face that it is irrevocable shall be governed by the
provisions of Section 212(e) of the General Corporation Law of Delaware.

                                  ARTICLE III

                                   DIRECTORS
                                   ---------
     3.1  POWERS.
          ------

          Subject to the provisions of the General Corporation Law of Delaware
and any limitations in the Certificate of Incorporation or these Bylaws relating
to action required to be approved by the stockholders or by the outstanding

                                      -4-
<PAGE>

shares, the business and affairs of the Corporation shall be managed and all
corporate powers shall be exercised by or under the direction of the Board of
Directors.

     3.2  NUMBER OF DIRECTORS.
          -------------------

          The number of directors constituting the entire Board of Directors
shall be seven (7).  Thereafter, this number may be changed by a resolution of
the Board of Directors or of the stockholders, subject to Section 3.4 of these
Bylaws and the Certificate of Incorporation.  No reduction of the authorized
number of directors shall have the effect of removing any director before such
director's term of office expires.

     3.3  ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTORS.
          -------------------------------------------------------

          Except as provided in Section 3.4 of these Bylaws, directors shall be
elected at each annual meeting of stockholders to hold office until the next
annual meeting.  Directors need not be stockholders unless so required by the
Certificate of Incorporation or these Bylaws, wherein other qualifications for
directors may be prescribed.  Each director, including a director elected to
fill a vacancy, shall hold office until his or her successor is elected and
qualified or until his or her earlier resignation or removal.

     3.4  RESIGNATION AND VACANCIES.
          -------------------------

          Any director may resign at any time upon written notice to the
attention of the secretary of the Corporation.  When one or more directors so
resigns and the resignation is effective at a future date, a majority of the
directors then in office, including those who have so resigned, shall have power
to fill such vacancy or vacancies, the vote thereon to take effect when such
resignation or resignations shall become effective, and each director so chosen
shall hold office as provided in this section in the filling of other vacancies.
A vacancy created by the removal of a director by the vote of the stockholders
or by court order may be filled only by the affirmative vote of a majority of
the shares represented and voting at a duly held meeting at which a quorum is
present (which shares voting affirmatively also constitute a majority of the
quorum).  Each director so elected shall hold office until the next annual
meeting of the stockholders and until a successor has been elected and
qualified.

          Unless otherwise provided in the Certificate of Incorporation or
these Bylaws:

          (a) Vacancies and newly created directorships resulting from any
increase in the authorized number of directors elected by all of the
stockholders having the right to vote as a single class may be filled by a
majority of the directors then in office, although less than a quorum, or by a
sole remaining director.

          (b) Whenever the holders of any class or classes of stock or series
thereof are entitled to elect one or more directors by the provisions of the
Certificate of Incorporation, vacancies and newly created directorships of such
class or classes or series may be filled by a majority of the directors elected
by such class or classes or series thereof then in office, or by a sole
remaining director so elected.

          If at any time, by reason of death or resignation or other cause, the
Corporation should have no directors in office, then any officer or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary entrusted with like responsibility for the person or estate
of a stockholder, may call a special meeting of stockholders in accordance with
the provisions of the Certificate of Incorporation or these Bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the General Corporation Law of Delaware.

          If, at the time of filling any vacancy or any newly created
directorship, the directors then in office constitute less than a majority of
the whole Board of Directors (as constituted immediately prior to any such
increase), then the Court of Chancery may, upon application of any stockholder
or stockholders holding at least 10% of the total number of the shares at the
time outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by

                                      -5-
<PAGE>

the directors then in office as aforesaid, which election shall be governed by
the provisions of Section 211 of the General Corporation Law of Delaware as far
as applicable.

     3.5  PLACE OF MEETINGS; MEETINGS BY TELEPHONE.
          ----------------------------------------

          The Board of Directors of the Corporation may hold meetings, both
regular and special, either within or outside the State of Delaware.  Unless
otherwise restricted by the Certificate of Incorporation or these Bylaws,
members of the Board of Directors, or any committee designated by the Board of
Directors, may participate in a meeting of the Board of Directors, or any
committee, by means of conference telephone or similar communications equipment
by means of which all persons participating in the meeting can hear each other,
and such participation in a meeting shall constitute presence in person at the
meeting.

     3.6  REGULAR MEETINGS.
          ----------------

          Regular meetings of the Board of Directors may be held without notice
at such time and at such place as shall from time to time be determined by the
Board of Directors.

     3.7  SPECIAL MEETINGS; NOTICE.
          ------------------------

          Special meetings of the Board of Directors for any purpose or purposes
may be called at any time by the chairman of the board, the president, any vice
president, the secretary or any two directors.

          Notice of the time and place of special meetings shall be delivered
personally, by facsimile or by telephone to each director or sent by first-class
mail or telegram, charges prepaid, addressed to each director at that director's
address as it is shown on the records of the Corporation.  If the notice is
mailed, it shall be deposited in the United States mail at least four days
before the time of the holding of the meeting.  If the notice is delivered
personally, by facsimile or by telephone or telegram, it shall be delivered
personally, by facsimile or by telephone or to the telegraph company at least 48
hours before the time of the holding of the meeting.  Any oral notice given
personally, by facsimile or by telephone may be communicated either to the
director or to a person at the office of the director who the person giving the
notice has reason to believe will promptly communicate it to the director.  The
notice need not specify the purpose or the place of the meeting, if the meeting
is to be held at the principal executive office of the Corporation.  It shall
not be necessary that the same method of giving notice be employed in respect of
all directors.

     3.8  QUORUM.
          ------

          At all meetings of the Board of Directors, a majority of the
authorized number of directors shall constitute a quorum for the transaction of
business and the act of a majority of the directors present at any meeting at
which there is a quorum shall be the act of the Board of Directors, except as
may be otherwise specifically provided by statute or by the Certificate of
Incorporation.  If a quorum is not present at any meeting of the Board of
Directors, then the directors present thereat may adjourn the meeting from time
to time, without notice other than announcement at the meeting, until a quorum
is present.

          A meeting at which a quorum is initially present may continue to
transact business notwithstanding the withdrawal of directors, if any action
taken is approved by at least a majority of the required quorum for that
meeting.

     3.9  WAIVER OF NOTICE.
          ----------------

          Whenever notice is required to be given under any provision of the
General Corporation Law of Delaware or of the Certificate of Incorporation or
these Bylaws, a written waiver thereof, signed by the person entitled to notice,
whether before or after the time stated therein, shall be deemed equivalent to
notice.  Attendance of a person at a meeting shall constitute a waiver of notice
of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business

                                      -6-
<PAGE>

because the meeting is not lawfully called or convened. Neither the business to
be transacted at, nor the purpose of, any regular or special meeting of the
directors, or members of a committee of directors, need be specified in any
written waiver of notice unless so required by the Certificate of Incorporation
or these Bylaws.

     3.10 BOARD ACTION BY WRITTEN CONSENT WITHOUT A MEETING.
          -------------------------------------------------

          Unless otherwise restricted by the Certificate of Incorporation or
these Bylaws, any action required or permitted to be taken at any meeting of the
Board of Directors, or of any committee thereof, may be taken without a meeting
if all members of the Board of Directors or committee, as the case may be,
consent thereto in writing and the writing or writings are filed with the
minutes of proceedings of the Board of Directors or committee.  Written consents
representing actions taken by the board or committee may be executed by telex,
telecopy or other facsimile transmission, and such facsimile shall be valid and
binding to the same extent as if it were an original.

     3.11 FEES AND COMPENSATION OF DIRECTORS.
          ----------------------------------

          Unless otherwise restricted by the Certificate of Incorporation or
these Bylaws, the Board of Directors shall have the authority to fix the
compensation of directors.  No such compensation shall preclude any director
from serving the Corporation in any other capacity and receiving compensation
therefor.

     3.12 APPROVAL OF LOANS TO OFFICERS.
          -----------------------------

          The Corporation may lend money to, or guarantee any obligation of, or
otherwise assist any officer or other employee of the Corporation or of its
subsidiary, including any officer or employee who is a director of the
Corporation or its subsidiary, whenever, in the judgment of the directors, such
loan, guaranty or assistance may reasonably be expected to benefit the
Corporation.  The loan, guaranty or other assistance may be with or without
interest and may be unsecured, or secured in such manner as the Board of
Directors shall approve, including, without limitation, a pledge of shares of
stock of the Corporation.  Nothing in this Section 3.2 contained shall be deemed
to deny, limit or restrict the powers of guaranty or warranty of the Corporation
at common law or under any statute.

     3.13 REMOVAL OF DIRECTORS.
          --------------------

          Unless otherwise restricted by statute, by the Certificate of
Incorporation or by these Bylaws, any director or the entire Board of Directors
may be removed, with or without cause, by the holders of a majority of the
shares then entitled to vote at an election of directors; provided, however,
that if the stockholders of the Corporation are entitled to cumulative voting,
if less than the entire Board of Directors is to be removed, no director may be
removed without cause if the votes cast against his removal would be sufficient
to elect him if then cumulatively voted at an election of the entire Board of
Directors.

          No reduction of the authorized number of directors shall have the
effect of removing any director prior to the expiration of such director's term
of office.

                                  ARTICLE IV

                                  COMMITTEES

Directors may designate one or more directors as alternate members of any
committee, who may replace any absent or disqualified member at any meeting of
the committee.  In the absence or disqualification of a member of a committee,
the member or members thereof present at any meeting and not disqualified from

absent or disqualified member. Any such committee, to the extent provided in the
resolution of the Board of Directors or in the Bylaws of the Corporation, shall
have and may exercise all the powers and authority of the Board of Directors in
the management of the business and affairs of the Corporation, and may authorize
the seal of the Corporation to be affixed to all papers that may require it; but
no such committee shall have the power or authority to (a) amend the Certificate
of Incorporation (except that a committee may, to the extent authorized in the
resolution or resolutions providing for the issuance of shares of stock adopted
by the Board of Directors as provided in Section 151(a) of the General
Corporation Law of Delaware, fix the designations and any of the preferences or
rights of such shares relating to dividends, redemption, dissolution, any
distribution of assets of the Corporation or the conversion into, or the
exchange of such shares for, shares of any other class or classes or any other
series of the same or any other class or classes of stock of the Corporation or

resolution establishing the committee, the Bylaws or the Certificate of
Incorporation expressly so provide, no such committee shall have the power or
authority to declare a dividend, to authorize the issuance of stock, or to adopt
a certificate of ownership and merger pursuant to Section 253 of the General
Corporation Law of Delaware.

     4.2  COMMITTEE MINUTES.

          Expenses incurred in defending any action or proceeding for which
indemnification is required pursuant to Section 6.1 or for which indemnification
is permitted pursuant to Section 6.2 following authorization thereof by the
Board of Directors shall be paid by the Corporation in advance of the final
disposition of such action or proceeding upon receipt of an undertaking by or on
behalf of the indemnified party to repay such amount if it shall ultimately be
determined that the indemnified party is not entitled to be indemnified as
authorized in this Article VI.

     6.4  INDEMNITY NOT EXCLUSIVE.
          -----------------------

          The indemnification provided by this Article VI shall not be deemed
exclusive of any other rights to which those seeking indemnification may been
titled under any Bylaw, agreement, vote of shareholders or disinterested
directors or otherwise, both as to action in an official capacity and as to
action in another capacity while holding such office, to the extent that such
additional rights to indemnification are authorized in the Certificate of
Incorporation.

employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against him or her and incurred
by him or her in any such capacity, or arising out of his or her status as such,

against such liability under the provisions of the General Corporation Law of
Delaware.

     6.6  CONFLICTS.
          ---------

          No indemnification or advance shall be made under this Article VI,
except where such indemnification or advance is mandated by law or the order,
judgment or decree of any court of competent jurisdiction, in any circumstance
where it appears:

                                      -11-
<PAGE>

          (a) That it would be inconsistent with a provision of the Certificate
of Incorporation, these Bylaws, a resolution of the stockholders or an agreement
in effect at the time of the accrual of the alleged cause of the action asserted
in the proceeding in which the expenses were incurred or other amounts were
paid, which prohibits or otherwise limits indemnification; or

               (b) That it would be inconsistent with any condition expressly
imposed by a court in approving a settlement.

Corporation's stock ledger, a list of its stockholders, and its other books and
records and to make copies or extracts therefrom.  A proper purpose shall mean a
purpose reasonably related to such person's interest as a stockholder.  In every
instance where an attorney or other agent is the person who seeks the right to
inspection, the demand under oath shall be accompanied by a power of attorney or
such other writing that authorizes the attorney or other agent to so act on
behalf of the stockholder.  The demand under oath shall be directed to the
Corporation at its registered office in Delaware or at its principal place of
business.

     7.2  INSPECTION BY DIRECTORS.
          -----------------------

          Any director shall have the right to examine the Corporation's
stockledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his or her position as a director.  The Court of
Chancery is hereby vested with the exclusive jurisdiction to determine whether a
director is entitled to the inspection sought.  The Court may summarily order
the Corporation to permit the director to inspect any and all books and records,
the stock ledger, and the stock list and to make copies or extracts therefrom.
The Court may, in its discretion, prescribe any limitations or conditions with
reference to the inspection, or award such other and further relief as the Court
may deem just and proper.

          The Board of Directors, except as otherwise provided in these Bylaws,
may authorize any officer or officers, or agent or agents, to enter into any
contract or execute any instrument in the name of and on behalf of the
Corporation; such authority may be general or confined to specific instances.

authority to bind the Corporation by any contract or engagement or to pledge its
credit or to render it liable for any purpose or for any amount.

     8.3  STOCK CERTIFICATES; PARTLY PAID SHARES.
          --------------------------------------

          The shares of the Corporation shall be represented by certificates,
provided that the Board of Directors of the Corporation may provide by
resolution or resolutions that some or all of any or all classes or series of
its stock shall be uncertificated shares.  Any such resolution shall not apply
to shares represented by a certificate until such certificate is surrendered to
the Corporation.  Notwithstanding the adoption of such a resolution by the Board
of Directors, every holder of stock represented by certificates and upon request
every holder of uncertificated shares shall be entitled to have a certificate
signed by, or in the name of the Corporation by the chairman or vice-chairman of
the Board of Directors, or the chief executive officer or the president or vice-
president, and by the chief financial officer or an assistant treasurer, or the
secretary or an assistant secretary of the Corporation representing the number
of shares registered in certificate form.  Any or all of the signatures on the
certificate may be a facsimile.  In case any officer, transfer agent or
registrar who has signed or whose facsimile signature has been placed upon a
certificate has ceased to be such officer, transfer agent or registrar before
such certificate is issued, it may be issued by the Corporation with the same
effect as if he or she were such officer, transfer agent or registrar at the

partly paid and subject to call for the remainder of the consideration to be
paid therefor.  Upon the face or back of each stock certificate issued to
represent any such partly paid shares, upon the books and records of the
Corporation in the case of uncertificated partly paid shares, the total amount
of the consideration to be paid therefor and the amount paid thereon shall be
stated.  Upon the declaration of any dividend on fully paid shares, the
Corporation shall declare a dividend upon partly paid shares of the same class,
but only upon the basis of the percentage of the consideration actually paid
thereon.

     8.4  SPECIAL DESIGNATION ON CERTIFICATES.
          -----------------------------------

          If the Corporation is authorized to issue more than one class of stock

preferences, and the relative, participating, optional or other special rights
of each class of stock or series thereof and the qualifications, limitations or
restrictions of such preferences and/or rights shall be set forth in full or
summarized on the face or back of the certificate that the Corporation shall
issue to represent such class or series of stock; provided, however, that,
except as otherwise provided in Section 202 of the General Corporation Law of
Delaware, in lieu of the foregoing requirements there may be set forth on the
face or back of the certificate that the Corporation shall issue to represent
such class or series of stock a statement that the Corporation will furnish
without charge to each stockholder who so requests the powers, the designations,
the preferences, and the relative, participating, optional or other special
rights of each class of stock or series thereof and the qualifications,
limitations or restrictions of such preferences and/or rights.

          Except as provided in this Section 8.5, no new certificates for shares
shall be issued to replace a previously issued certificate unless the latter is
surrendered to the Corporation and canceled at the same time.  The Corporation
may issue a new certificate of stock or uncertificated shares in the place of
any certificate previously issued by it, alleged to have been lost, stolen or
destroyed, and the Corporation may require the owner of the lost, stolen or
destroyed certificate, or the owner's legal representative, to give the
Corporation a bond sufficient to

                                      -13-
<PAGE>

indemnify it against any claim that may be made against it on account of the
alleged loss, theft or destruction of any such certificate or the issuance of
such new certificate or uncertificated shares.

     8.6  CONSTRUCTION; DEFINITIONS.
          -------------------------

includes the singular, and the term "person" includes both a corporation and a
natural person.

of the Corporation available for dividends a reserve or reserves for any proper
purpose and may abolish any such reserve.  Such purposes shall include but not

thereto, cancel the old certificate, and record the transaction in its books.

     8.11 STOCK TRANSFER AGREEMENTS.
          -------------------------

          The Corporation shall have power to enter into and perform any

of any one or more classes owned by such stockholders in any manner not
prohibited by the General Corporation Law of Delaware.

     8.12 REGISTERED STOCKHOLDERS.

a person registered on its books as the owner of shares to receive dividends and
to vote as such owner, shall be entitled to hold liable for calls and
assessments the person registered on its books as the owner of shares, and shall
not be bound to recognize any equitable or other claim to or interest in such

          The Bylaws of the Corporation may be adopted, amended or repealed by a
majority of the stockholders entitled to vote; provided, however, that the
                                               -----------------
Corporation may, in its Certificate of Incorporation, confer the power to adopt,

repealed only by the affirmative vote of a majority of the voting power of all
of the then-outstanding shares of the voting stock of the Corporation entitled
to vote, and Section 3.2 herein may only be amended or repealed by the Board to
the extent allowed by the Certificate of Incorporation.  The fact that the power
to adopt, amend or repeal the bylaws has been so conferred upon the directors
shall not divest the stockholders of such power, nor limit their power to adopt,
amend or repeal Bylaws.

     Except as otherwise provided for herein, the term of this Warrant Agreement
and the right to purchase Preferred Stock as granted herein shall commence on
the Effective Date and shall be exercisable for a period of (i) seven (7) years
from the date hereof or (ii) three (3) years from the effective date of the
Company's initial public offering, whichever is shorter.

3.   EXERCISE OF THE PURCHASE RIGHTS.
     -------------------------------

     The purchase rights set forth in this Warrant Agreement are exercisable by
the Warrantholder, in whole or in part, at any time, or from time to time after
the issuance and sale of any Series E Preferred Stock by the Company and, prior
to the expiration of the term set forth in Section 2 above, by tendering to the
Company at its principal office a notice of exercise the form attached hereto as
Exhibit I (the "Notice of Exercise"), duly completed and executed.  Promptly
upon receipt of the Notice of Exercise and the payment of the purchase price in
accordance with

                                      -1-
<PAGE>

the terms set forth below, and in no event later than twenty-one (21) days
thereafter, the Company shall issue to the Warrantholder a certificate for the
number of shares of Preferred Stock purchased and shall execute the
acknowledgment of exercise in the form attached hereto as Exhibit II (the
"Acknowledgment of Exercise") indicating the number of shares which remain
subject to future purchases, if any.

     The Exercise Price may be paid at the Warrantholder's election either (i)
by cash or check, or (ii) by surrender of Warrants ("Net Issuance") as
determined below.  If the Warrantholder elects the Net Issuance method, the
Company will issue Preferred Stock in accordance with the following formula:

             X = Y(A-B)
                  -----
                    A

     Where:  X =  the number of shares of Preferred Stock to be issued to the
                  Warrantholder.

             Y =  the number of shares of Preferred Stock requested to be
                  exercised under this Warrant Agreement.

             A =  the fair market value of one (1) share of Preferred Stock.

             B =  the Exercise Price.

     For purposes of the above calculation, current fair market value of
Preferred Stock shall mean with respect to each share of Preferred Stock:

          (i) if the exercise is in connection  with an initial public offering
     of the Company's Common Stock, and if the Company's Registration Statement
     relating to such public offering has been declared effective by the SEC,
     then the fair market value per share shall be the product of (x) the
     initial "Price to Public" specified in the final prospectus with respect to
     the offering and (y) the number of shares of Common Stock into which each
     share of Preferred Stock is convertible at the time of such exercise;

          (ii) if this Warrant is exercised after, and not in connection with
     the Company's initial public offering, and:

               (a) if traded on a securities exchange, the fair market value
          shall be deemed to be the product of (x) the average of the closing
          prices over a twenty-one (21) day period ending three days before the
          day the current fair market value of the securities is being
          determined and (y) the number of shares of Common Stock into which
          each share of Preferred Stock is convertible at the time of such
          exercise; or

               (b) if actively traded over-the-counter, the fair market value
          shall be deemed to be the product of (x) the average of the closing
          bid and asked prices quoted on the NASDAQ system (or similar system)
          over the twenty-one (21) day period ending three days before the day
          the current fair market value of the securities is being determined
          and (y) the number of shares of Common Stock into which each share of
          Preferred Stock is convertible at the time of such exercise;

          (iii)  if at any time the Common Stock is not listed on any securities
     exchange or quoted in the NASDAQ System or the over-the-counter market, the
     current fair market value of Preferred Stock shall be the product of (x)
     the highest price per share which the Company could obtain from a willing
     buyer (not a current employee or director) for shares of Common Stock sold
     by the Company, from authorized but unissued shares, as determined in good
     faith by its Board of Directors and (y) the number of shares of Common
     Stock into which each share of Preferred Stock is convertible at the time
     of such exercise, unless the Company shall become subject to a merger,
     acquisition or other consolidation pursuant to which the

                                      -2-
<PAGE>

     Company is not the surviving party, in which case the fair market value of
     Preferred Stock shall be deemed to be the value received by the holders of
     the Company's Preferred Stock on a common equivalent basis pursuant to such
     merger or acquisition.

     Upon partial exercise by either cash or Net Issuance, the Company shall
promptly issue an amended Warrant Agreement representing the remaining number of
shares purchasable hereunder.  All other terms and conditions of such amended
Warrant Agreement shall be identical to those contained herein, including, but
not limited to the Effective Date hereof.

4.   RESERVATION OF SHARES.
     ---------------------

          (a) Authorization and Reservation of Shares.  During the term of this
              ---------------------------------------
Warrant Agreement, the Company will authorize and reserve a sufficient number of
shares of its Preferred Stock to provide for the exercise of the rights to
purchase Preferred Stock as provided for herein.

          (b) Registration or Listing.  If any shares of Preferred Stock
              -----------------------
required to be reserved hereunder require registration with or approval of any
governmental authority under any Federal or State law (other than any
registration under the Securities Act of 1933, as amended ("1933 Act"), as then
in effect, or any similar Federal statute then enforced, or any state securities
law, required by reason of any transfer involved in such conversion), or listing
on any domestic securities exchange, before such shares may be issued upon
conversion, the Company will, at its expense and as reasonably expeditiously as
possible, use its best efforts to cause such shares to be duly registered,
listed or approved for listing on such domestic securities exchange, as the case
may be.

5.   NO FRACTIONAL SHARES OR SCRIP.
     -----------------------------

     No fractional shares or scrip representing fractional shares shall be
issued upon the exercise of the Warrant, but in lieu of such fractional shares
the Company shall make a cash payment therefor upon the basis of the Exercise
Price then in effect.

6.   NO RIGHTS AS SHAREHOLDER.
     ------------------------

     This Warrant Agreement does not entitle the Warrantholder to any voting
rights or other rights as a shareholder of the Company prior to the exercise of
the Warrant.

7.   WARRANTHOLDER REGISTRY.
     ----------------------

     The Company shall maintain a registry showing the name and address of the
registered holder of this Warrant Agreement.

8.   ADJUSTMENT RIGHTS.
     -----------------

     The purchase price per share and the number of shares of Preferred Stock
purchasable hereunder are subject to adjustment, as follows:

     (a) Merger and Sale of Assets.  If at any time there shall be a capital
         -------------------------
reorganization of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation whether or not the Company is the surviving corporation, or the sale
of all or substantially all of the Company's properties and assets to any other
person (hereinafter referred to as a "Merger Event"), then, as a part of such
Merger Event, lawful provision shall be made so that the Warrantholder shall
thereafter be entitled to receive, upon exercise of the Warrant, the number of
shares of preferred stock or other securities of the successor corporation
resulting from such Merger Event, equivalent in value to that which would have
been issuable if Warrantholder had exercised this Warrant immediately prior to
the Merger Event.  In any such case, appropriate adjustment (as determined in
good faith by the

                                      -3-
<PAGE>

Company's Board of Directors) shall be made in the application of the provisions
of this Warrant Agreement with respect to the rights and interest of the
Warrantholder after the Merger Event to the end that the provisions of this
Warrant Agreement (including adjustments of the Exercise Price and number of
shares of Preferred Stock purchasable) shall be applicable to the greatest
extent possible.

     (b) Reclassification of Shares.  If the Company at any time shall, by
         --------------------------
combination, reclassification, exchange or subdivision of securities or
otherwise, change any of the securities as to which purchase rights under this
Warrant Agreement exist into the same or a different number of securities of any
other class or classes, this Warrant Agreement shall thereafter represent the
right to acquire such number and kind of securities as would have been issuable
as the result of such change with respect to the securities which were subject
to the purchase rights under this Warrant Agreement immediately prior to such
combination, reclassification, exchange, subdivision or other change.

     (c) Subdivision or Combination of Shares.  If the Company at any time shall
         ------------------------------------
combine or subdivide its Preferred Stock, the Exercise Price shall be
proportionately decreased in the case of a subdivision, or proportionately
increased in the case of a combination.

     (d) Stock Dividends.  If the Company at any time shall pay a dividend
         ---------------
payable in, or make any other distribution (except any distribution specifically
provided for in the foregoing subsections (a) or (b)) of the Company's stock,
then the Exercise Price shall be adjusted, from and after the record date of
such dividend or distribution, to that price determined by multiplying the
Exercise Price in effect immediately prior to such record date by a fraction (i)
the numerator of which shall be the total number of all shares of the Company's
stock outstanding immediately prior to such dividend or distribution, and (ii)
the denominator of which shall be the total number of all shares of the
Company's stock outstanding immediately after such dividend or distribution.
The Warrantholder shall thereafter be entitled to purchase, at the Exercise
Price resulting from such adjustment, the number of shares of Preferred Stock
(calculated to the nearest whole share) obtained by multiplying the Exercise
Price in effect immediately prior to such adjustment by the number of shares of
Preferred Stock issuable upon the exercise hereof immediately prior to such
adjustment and dividing the product thereof by the Exercise Price resulting from
such adjustment.

     (e) Right to Purchase Additional Stock.  If the Company has not paid any
         ----------------------------------
Subordinated Promissory Note(s) entered into pursuant to the Loan(s) in its
entirety by the Maturity Date (as defined in the applicable Subordinated
Promissory Note(s)), then for each additional month, or portion thereof,
thereafter that the outstanding principal is not paid, Warrantholder shall have
the right to purchase from the Company, at the Exercise Price (adjusted as set
forth herein), an additional number of shares of Preferred Stock which number
shall be determined by (i) multiplying the outstanding principal amount which
due but unpaid by 1% and (ii) dividing the product thereof by the Exercise
Price.

     (f) Antidilution Rights.  Additional antidilution rights applicable to the
         -------------------
Preferred Stock purchasable hereunder are as set forth in the Company's Amended
and Restated Certificate of incorporation, as amended through the Effective
Date, a true and complete copy of which is attached hereto as Exhibit IV (the
                                                                      --
"Charter").  The Company shall promptly provide the Warrantholder with any
restatement, amendment, modification or waiver of the Charter.  The Company
shall provide Warrantholder with prior written notice of any issuance of its
stock or other equity security that, pursuant to Article IV, Section 3 of the
Charter would require an adjustment to the conversion price of the Series E
Preferred Stock to occur after the Effective Date of this Warrant, which notice
shall include (a) the price at which such stock or security is to be sold, (b)
the number of shares to be issued, and (c) such other information as necessary
for Warrantholder to determine if a dilutive event has occurred.

     (g) Notice of Adjustments.  If:  (i) the Company shall declare any dividend
         ---------------------
or distribution upon its stock, whether in cash, property, stock or other
securities; (ii) the Company shall offer for subscription prorata to the holders
of any class of its Preferred or other convertible stock any additional shares
of stock of any class or other rights; (iii) there shall be any Merger Event;
(iv) there shall be an initial public offering; or (v) there shall be any
voluntary dissolution, liquidation or winding up of the Company; then, in
connection with each such event, the

                                      -4-
<PAGE>

Company shall send to the Warrantholder (A) at least ten (10) days' prior
written notice of the date on which the books of the Company shall close or a
record shall be taken for such dividend, distribution, subscription rights (and
specifying the date on which the holders of Preferred Stock shall be entitled
thereto) or for determining rights to vote in respect of such Merger Event,
dissolution, liquidation or winding up; (B) in the case of any such Merger
Event, dissolution, liquidation or winding up, at least ten (10) days' prior
written notice of the date when the same shall take place (and specifying the
date on which the holders of Preferred Stock shall be entitled to exchange their
Preferred Stock for securities or other property deliverable upon such Merger
Event, dissolution, liquidation or winding up); and (C) in the case of a public
offering, the Company shall give the Warrantholder at least ten (10) days
written notice prior to the effective date thereof.

     Each such written notice shall set forth, in reasonable detail, (i) the
event requiring the adjustment, (ii) the amount of the adjustment, (iii) the
method by which such adjustment was calculated, (v) the Exercise Price, and (v)
the number of shares subject to purchase hereunder after giving effect to such
adjustment, and shall be given by first class mail, postage prepaid, addressed
to the Warrantholder, at the address as shown on the books of the Company.

     (h) Timely Notice.  Failure to timely provide such notice required by
         -------------
subsection (g) above shall entitle Warrantholder to retain the benefit of the
applicable notice Period notwithstanding anything to the contrary contained in
any insufficient notice received by Warrantholder.  The notice period shall
begin on the date Warrantholder actually receives a written notice containing
all the information specified above.

upon the following representations and covenants of the Warrantholder.

                                      -6-
<PAGE>

     (a) Investment Purpose.  The right to acquire Preferred Stock or the
         ------------------
Preferred Stock issuable upon exercise of the Warrantholder's rights contained
herein will be acquired for investment and not with a view to the sale or
distribution of any part thereof, and the Warrantholder has no present intention
of selling or engaging in any public distribution of the same except pursuant to
a registration or exemption.

     (b) Private Issue.  The Warrantholder understands (i) that the Preferred
         -------------
Stock issuable upon exercise of this Warrant is not registered under the 1933
Act or qualified under applicable state securities laws on the ground that the
issuance contemplated by this Warrant Agreement will be exempt from the
registration and qualifications requirements thereof, and (ii) that the
Company's reliance on such exemption is predicated on the representations set
forth in this Section 10.

     (c) Disposition of Warrantholder's Rights.  In no event will the
         -------------------------------------
Warrantholder make a disposition of any of its rights to acquire Preferred Stock
or Preferred Stock issuable upon exercise of such rights unless and until it
shall have notified the Company of the proposed disposition, and (ii) if
requested by the Company, it shall have furnished the Company with an opinion of
counsel (which counsel may either be inside or outside counsel to the
Warrantholder) satisfactory to the Company and its counsel to the effect that
(A) appropriate action necessary for compliance with the 1933 Act has been
taken, or (B) an exemption from the registration requirements of the 1933 Act is
available.  Notwithstanding the foregoing, the restrictions imposed upon the
transferability of any of its rights to acquire Preferred Stock or Preferred
Stock issuable on the exercise of such rights do not apply to transfers from the
beneficial owner of any of the aforementioned securities to its nominee or from
such nominee to its beneficial owner, and shall terminate as to any particular
share of Preferred Stock when (1) such security shall have been effectively
registered under the 1933 Act and sold by the holder thereof in accordance with
such registration or (2) such security shall have been sold without registration
in compliance with Rule 144 under the 1933 Act, or (3) a letter shall have been
issued to the Warrantholder at its request by the staff of the Securities and
Exchange Commission or a ruling shall have been issued to the Warrantholder at
its request by such Commission stating that no action shall be recommended by
such staff or taken by such Commission, as the case may be, if such security is
transferred without registration under the 1933 Act in accordance with the
conditions set forth in such letter or ruling and such letter or ruling
specifies that no subsequent restrictions on transfer are required.  Whenever
the restrictions imposed hereunder shall terminate, as hereinabove provided, the
Warrantholder or holder of a share of Preferred Stock then outstanding as to
which such restrictions have terminated shall be entitled to receive from the
Company, without expense to such holder, one or more new certificates for the
Warrant or for such shares of Preferred Stock not bearing any restrictive
legend.

     (d) Financial Risk.  The Warrantholder has such knowledge and experience in
         --------------
financial and business matters as to be capable of evaluating the merits and
risks of its investment, and has the ability to bear the economic risks of its
investment.

     (e) Risk of No Registration.  The Warrantholder understands that if the
         -----------------------
Company does not register with the Securities and Exchange Commission pursuant
to Section 12 of the 1934 Act (the "1934 Act"), or file reports pursuant to
Section 15(d), of the 1934 Act, or if a registration statement covering the
securities under the 1933 Act is not in effect when it desires to sell (i) the
rights to purchase Preferred Stock pursuant to this Warrant Agreement, or (ii)
the Preferred Stock issuable upon exercise of the right to purchase, it may be
required to hold such securities for an indefinite period.  The Warrantholder
also understands that any sale of its rights of the Warrantholder to purchase
Preferred Stock or Preferred Stock which might be made by it in reliance upon
Rule 144 under the 1933 Act may be made only in accordance with the terms and
conditions of that Rule.

     (f) Accredited Investor.  Warrantholder is an "accredited investor" within
         -------------------
the meaning of the Securities and Exchange Rule 501 of Regulation D.  as
presently in effect.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT
AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
"1933 ACT") OR ANY STATE SECURITIES LAWS.  SUCH SECURITIES MAY NOT BE SOLD OR
TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER
THE 1933 ACT AND ANY APPLICABLE STATE SECURITIES LAWS.

                       WARRANT TO PURCHASE 177,098 SHARES
                             OF THE COMMON STOCK OF
                           CrossWorlds Software, Inc.
                          (Void after October 7, 2006)

     This certifies that Heidrick & Struggles, Inc. or its assigns (each
individually, the "Holder") for value received, shall be entitled to purchase
from CrossWorlds Software, Inc. a Delaware corporation (the "Company"), having
its principal place of business at 577 Airport Boulevard, Suite 800, Burlingame,
California 94010-2024, a maximum of 177,098 fully paid and nonassessable shares
of the Company's Common Stock ("Common Stock") for cash at a price equal to
$6.60 per share (the "Exercise Price") at any time, or from time to time, up to
and including 5:00 p.m. (local time) on the seventh anniversary from the date of
this Warrant (the "Expiration Date"), upon the surrender to the Company at its
principal place of business (or at such other location as the Company may advise
the Holder in writing) of this Warrant properly endorsed a Form of Subscription
in substantially the form attached hereto duly filled in and signed and, if
applicable, upon payment in cash or by check of the aggregate Exercise Price for
the number of shares for which this Warrant is being exercised determined in
accordance with the provisions hereof.  The Exercise Price and the number of
shares of Common Stock purchasable hereunder are subject to adjustment as
provided in Section 3 of this Warrant.

     This Warrant is subject to the following terms and conditions:

     1.  Exercise; Issuance of Certificates; Payment for Shares.

            1.1  General. This Warrant is exercisable at the option of the
holder of record hereof at any time or from time, to time, up to the
Expiration Date for all or any part of the shares of Common Stock (but not for
a fraction of a share) which may be purchased hereunder. The Company agrees
that the shares of Common Stock purchased under this Warrant shall be and are
deemed to be issued to the Holder hereof as the record owner of such shares as
of the close of business on the date on which this Warrant shall have been
surrendered, properly endorsed, the completed, executed Form of Subscription
delivered and payment made for such shares. Certificates for the shares of
Common Stock so purchased, together with any other securities or property to
which the Holder is entitled upon such exercise, shall be delivered to the
Holder by the Company at the Company's expense within a reasonable time after
the rights represented by this Warrant have been so exercised, and in any
event, within fifteen (15) days of such exercise. In case of a purchase of
less than all the shares which may be purchased under this Warrant, the
Company shall cancel this Warrant and execute and deliver a new Warrant or
Warrants of like tenor for the balance of the shares purchasable under the
Warrant surrendered upon such purchase to the Holder hereof within a
reasonable time. Each stock certificate so delivered shall
<PAGE>

be in such denominations of Common Stock as may be requested by the Holder
hereof and shall be registered in the name designated by such Holder.

            1.2  Net Issue Exercise. Notwithstanding any provisions herein to
the contrary, if the fair market value of one share of the Company's Common
Stock is greater than the Exercise Price (at the date of calculation as set
forth below), in lieu of exercising this Warrant for cash, the Holder may
elect to receive shares equal to the value (as determined below) of this
Warrant (or the portion thereof being canceled) by surrender of this Warrant
at the principal office of the Company together with the properly endorsed
Form of Subscription and notice of such election in which event the Company
shall issue to the Holder a number of shares of Common Stock computed using
the following formula:

                 X = Y (A-B)
                     -------
                        A

     Where X = the number of shares of Common Stock to be issued to the Holder

                                Y =  the number of shares of Common Stock
                                     purchasable under the Warrant or, if only
                                     a portion of the Warrant is being
                                     exercised, the portion of the Warrant
                                     being canceled (at the date of such
                                     calculation)

                                A =  the fair market value of one share of the
                                     Company's Common Stock (at the date of
                                     such calculation)

                                B =  Exercise Price (as adjusted to the date
                                     of such calculation).

For purposes of the above calculation, the fair market value of one share of
Common Stock shall be determined by the Company's Board of Directors in good
faith; provided, however, that where there is a public market for the Company's
Common Stock, the fair market value per share shall be the average of the
closing prices of the Company's Common Stock quoted on the Nasdaq National
Market (or similar system) or on any exchange on which the Common Stock is
listed, whichever is applicable, over the five (5) day period ending one (1) day
before the day the current fair market value is being determined.

        2.  Shares to be Fully Paid; Reservation of Shares. The Company
covenants and agrees that all shares of Common Stock which may be issued upon
the exercise of the rights represented by this Warrant will, upon issuance, be
duly authorized, validly issued, fully paid and nonassessable and free from
all preemptive rights of any shareholder and free of all taxes, liens and
charges with respect to the issue thereof. The Company further covenants and
agrees that, during the period within which the rights represented by this
Warrant may be exercised, the Company will at all times have authorized and
reserved, for the purpose of issue or transfer upon exercise of the
subscription rights evidenced by this Warrant, a sufficient number of shares
of authorized but unissued Common Stock, or other securities and property,
when and as required to provide for the exercise of the rights represented by
this Warrant. The Company will take all such action as may be necessary to
assure that such shares of Common Stock may be issued as

                                       2
<PAGE>

provided herein without violation of any applicable law or regulation, or of any
requirements of any domestic securities exchange upon which the Common Stock may
be listed; provided, however, that the Company shall not be required to effect a
registration under Federal or State securities laws with respect to such
exercise.  The Company will not take any action which would result in any
adjustment of the Exercise Price (as set forth in Section 3 hereof) if the total
number of shares of Common Stock issuable after such action upon exercise of all
outstanding warrants, together with all shares of Common Stock then outstanding
and all shares of Common Stock then issuable upon exercise of all options and
upon the conversion of all convertible securities then outstanding, would exceed
the total number of shares of Common Stock then authorized by the Company's
Certificate of Incorporation (the "Company Charter").

        3.  Adjustment of Exercise Price and Number of Shares. The Exercise
Price and the number of shares purchasable upon the exercise of this Warrant
shall be subject to adjustment from time to time upon the occurrence of
certain events described in this Section 3. Upon each adjustment of the
Exercise Price, the Holder of this Warrant shall thereafter be entitled to
purchase, at the Exercise Price resulting from such adjustment, the number of
shares obtained by multiplying the Exercise Price in effect immediately prior
to such adjustment by the number of shares purchasable pursuant hereto
immediately prior to such adjustment, and dividing the product thereof by the
Exercise Price resulting from such adjustment.

            3.1  Subdivision or Combination of Stock. In case the Company
shall at any time subdivide its outstanding shares of Common Stock into a
greater number of shares, the Exercise Price in effect immediately prior to
such subdivision shall be proportionately reduced, and conversely, in case the
outstanding shares of Common Stock of the Company shall be combined into a
smaller number of shares, the Exercise Price in effect immediately prior to
such combination shall be proportionately increased.

            3.2  Dividends in Common Stock, Other Stock, Property,
Reclassification. If at any time or from time to time the Holders of Common
Stock (or any shares of stock or other securities at the time receivable upon
the exercise of this Warrant) shall have received or become entitled to
receive, without payment therefor,

                  (a)  Common Stock or any shares of stock or other securities
which are at any time directly or indirectly convertible into or exchangeable
for Common Stock, or any rights or options to subscribe for, purchase or
otherwise acquire any of the foregoing by way of dividend or other
distribution,

                  (b)  any cash paid or payable otherwise than as a cash
dividend, or

                  (c)  Common Stock or additional stock or other securities or
property (including cash) by way of spinoff, split-up, reclassification,
combination of shares or similar corporate rearrangement, (other than shares
of Common Stock issued as a stock split or adjustments in respect of which
shall be covered by the terms of Section 3.1 above), then and in each such
case, the Holder hereof shall, upon the exercise of this Warrant, be entitled
to receive, in addition to the number of shares of Common Stock receivable
thereupon, and without payment of any additional consideration therefor, the
amount of stock and other securities and property (including cash in the cases
referred to in clause (b) above and this clause (c)) which

                                       3
<PAGE>

such Holder would hold on the date of such exercise had he been the holder of
record of such Common Stock as of the date on which holders of Common Stock
received or became entitled to receive such shares or all other
additional stock and other securities and property.

            3.3  Reorganization, Reclassification, Consolidation, Merger or
Sale. If any recapitalization, reclassification or reorganization of the
capital stock of the Company, or any consolidation or merger of the Company
with another corporation, or the sale of all or substantially all of its
assets or other transaction shall be effected in such a way that holders of
Common Stock shall be entitled to receive stock, securities, or other assets
or property (an "Organic Change"), then, as a condition of such Organic
Change, lawful and adequate provisions shall be made by the Company whereby
the Holder hereof shall thereafter have the right to purchase and receive (in
lieu of the shares of the Common Stock of the Company immediately theretofore
purchasable and receivable upon the exercise of the rights represented by this
Warrant) such shares of stock, securities or other assets or property as may
be issued or payable with respect to or in exchange for a number of
outstanding shares of such Common Stock equal to the number of shares of such
stock immediately theretofore purchasable and receivable upon the exercise of
the rights represented by this Warrant. In the event of any Organic Change,
appropriate provision shall be made by the Company with respect to the rights
and interests of the Holder of this Warrant to the end that the provisions
hereof (including, without limitation, provisions for adjustments of the
Exercise Price and of the number of shares purchasable and receivable upon the
exercise of this Warrant) shall thereafter be applicable, in relation to any
shares of stock, securities or assets thereafter deliverable upon the exercise
hereof. The Company will not effect any such consolidation, merger or sale
unless, prior to the consummation thereof, the successor corporation (if other
than the Company) resulting from such consolidation or the corporation
purchasing such assets shall assume by written instrument executed and mailed
or delivered to the registered Holder hereof at the last address of such
Holder appearing on the books of the Company, the obligation to deliver to
such Holder such shares of stock, securities or assets as, in accordance with
the foregoing provisions, such Holder may be entitled to purchase.

            3.4  Certain Events. If any change in the outstanding Common Stock
of the Company or any other event occurs as to which the other provisions of
this Section 3 are not strictly applicable or if strictly applicable would not
fairly protect the purchase rights of the Holder of the Warrant in accordance
with such provisions, then the Board of Directors of the Company shall make an
adjustment in the number and class of shares available under the Warrant, the
Exercise Price or the application of such provisions, so as to protect such
purchase rights as aforesaid. The adjustment shall be such as will give the
Holder of the Warrant upon exercise for the same aggregate Exercise Price the
total number, class and kind of shares as he would have owned had the Warrant
been exercised prior to the event and had he continued to hold such shares
until after the event requiring adjustment.

                                       4
<PAGE>

            3.5  Notices of Change.

                 (a)  Immediately upon any adjustment in the number or class
of shares subject to this Warrant and of the Exercise Price, the Company
shall give written notice thereof to the Holder, setting forth in
reasonable detail and certifying the calculation of such adjustment.

                 (b)  The Company shall give written notice to the Holder at
least 10 business days prior to the date on which the Company closes its books
or takes a record for determining rights to receive any dividends or
distributions.

                 (c)  The Company shall also give written notice to the Holder
at least 15 business days prior to the date on which an Organic Change shall
take place.

       4.  Issue Tax. The issuance of certificates for shares of Common Stock
upon the exercise of the Warrant shall be made without charge to the Holder of
the Warrant for any issue tax (other than any applicable income taxes) in
respect thereof; provided, however, that the Company shall not be required to
pay any tax which may be payable in respect of any transfer involved in the
issuance and delivery of any certificate in a name other than that of the then
Holder of the Warrant being exercised.

       5.  Closing of Books. The Company will at no time close its transfer
books against the transfer of any warrant or of any shares of Common Stock
issued or issuable upon the exercise of any warrant in any manner which
interferes with the timely exercise of this Warrant.

       6.  No Voting or Dividend Rights; Limitation of Liability. Nothing
contained in this Warrant shall be construed as conferring upon the Holder
hereof the right to vote or to consent or to receive notice as a shareholder
of the Company or any other matters or any rights whatsoever as a shareholder
of the Company. No dividends or interest shall be payable or accrued in
respect of this Warrant or the interest represented hereby or the shares
purchasable hereunder until, and only to the extent that, this Warrant shall
have been exercised. No provisions hereof, in the absence of affirmative
action by the holder to purchase shares of Common Stock, and no mere
enumeration herein of the rights or privileges of the holder hereof, shall
give rise to any liability of such Holder for the Exercise Price or as a
shareholder of the Company, whether such liability is asserted by the Company
or by its creditors.

       7.  Warrants Transferable. Subject to compliance with applicable
federal and state securities laws, and provided the Company receives prior
written notice, this Warrant and all rights hereunder are transferable, in
whole or in part, without charge to the holder hereof (except for transfer
taxes), upon surrender of this Warrant properly endorsed. Each taker and
holder of this Warrant, by taking or holding the same, consents and agrees
that this Warrant, when endorsed in blank, shall be deemed negotiable, and
that the holder hereof, when this Warrant shall have been so endorsed, may be
treated by the Company, at the Company's option, and all other persons dealing
with this Warrant as the absolute owner hereof for any purpose and as the
person entitled to exercise the rights represented by this Warrant, or to the
transfer hereof on the books of the Company any notice to the contrary
notwithstanding; but until such transfer on such books, the Company may treat
the registered owner hereof as the owner for all purposes. Notwithstanding the
foregoing, unless the Company is filing financial information with the SEC

                                       5
<PAGE>

pursuant to the Securities Exchange Act of 1934, the Company shall have the
right to refuse to transfer any portion of this Warrant to any person who
directly competes with the Company.

       8.  Rights and Obligations Survive Exercise of Warrant.  The rights and
obligations of the Company, of the holder of this Warrant and of the holder of
shares of Common Stock issued upon exercise of this Warrant, shall survive the
exercise of this Warrant.

       9.  Further Representations, Warranties and Covenants of the Company.

                 (a)  Articles and Bylaws. The Company has made available to
Holder true, complete and correct copies of the Company Charter and Bylaws, as
amended, through the date hereof.

                 (b)  Due Authority. The execution and delivery by the Company
of this Warrant and the performance of all obligations of the Company
hereunder, including the issuance to Holder of the right to acquire the shares
of Common Stock, have been duly authorized by all necessary corporate action
on the part of the Company, and the Warrant is not inconsistent with the
Company Charter or Bylaws and constitutes a legal, valid and binding agreement
of the Company, enforceable in accordance with its terms.

                 (c)  Consents and Approvals. No consent or approval of,
giving of notice to, registration with, or taking of any other action in
respect of any state, federal or other governmental authority or agency is
required with respect to the execution, delivery and performance by the
Company of its obligations under this Warrant, except for any filing required
by applicable federal and state securities laws, which filing will be
effective by the time required thereby.

                 (d)  Exempt Transaction. Subject to the accuracy of the
Holders representations in Section 10 hereof, the issuance of the Common Stock
upon exercise of this Warrant will constitute a transaction exempt from (i)
the registration requirements of Section 5 of the Securities Act of 1933, as
amended (the "1933 Act"), in reliance upon Section 4(2) thereof, and (ii) the
qualification requirements of the applicable state securities laws.

                 (e)  Compliance with Rule 144. At the written request of the
Holder, who proposes to sell Common Stock issuable upon the exercise of the
Warrant in compliance with Rule 144 promulgated by the Securities and Exchange
Commission, the Company shall furnish to the Holder, within thirty (30) days
after receipt of such request, a written statement confirming the Company's
compliance with the filing requirements of the Securities and Exchange
Commission as set forth in such Rule, as such Rule may be amended from time to
time.

       10.  Representations and Covenants of the Holder.

       This Warrant has been entered into by the Company in reliance upon the
following representations and covenants of the Holder:

                 (a)  Investment Purpose. The Warrant or the Common Stock
issuable upon exercise of the Warrant will be acquired for investment and not
with a view to the sale or distribution of any part thereof, and the Holder
has no present intention of selling or engaging in any public distribution of
the same except pursuant to a registration or exemption.

                 (b)  Private Issue. The Holder understands (i) that the
Warrant and the Common Stock issuable upon exercise of this Warrant is not
registered under the 1933 Act or qualified under applicable state securities
laws on the ground that the issuance contemplated by this Warrant will be
exempt from the registration and qualifications requirements thereof, and (ii)
that the Company's reliance on such exemption is predicated on the
representations set forth in this Section 10.

                 (c)  Disposition of Holders Rights. In no event will the
Holder make a disposition of the Warrant or the Common Stock issuable upon
exercise of the Warrant unless and until (i) it shall have notified the
Company of the proposed disposition, and (ii) if requested by the Company, it
shall have furnished the Company with an opinion of counsel (which counsel may
either be inside or outside counsel to the Holder) satisfactory to the Company
and its counsel to the effect that (A) appropriate action necessary for
compliance with the 1933 Act has been taken, or (B) an exemption from the
registration requirements of the 1933 Act is available. Notwithstanding the
foregoing, the restrictions imposed upon the transferability of any of its
rights to acquire Common Stock or Common Stock issuable on the exercise of
such rights do not apply to transfers from the beneficial owner of any of the
aforementioned securities to its nominee or from such nominee to its
beneficial owner, and shall terminate as to any particular share of Common
Stock when (1) such security shall have been effectively registered under the
1933 Act and sold by the holder thereof in accordance with such registration
or (2) such security shall have been sold without registration in compliance
with Rule 144 under the 1933 Act, or (3) a letter shall have been issued to
the Holder at its request by the staff of the Securities and Exchange
Commission or a ruling shall have been issued to the Holder at its request by
such Commission stating that no action shall be recommended by such staff or
taken by such Commission, as the case may be, if such security is transferred
without registration under the 1933 Act in accordance with the conditions set
forth in such letter or ruling and such letter or ruling specifies that no
subsequent restrictions on transfer are required. Whenever the restrictions
imposed hereunder shall terminate, as hereinabove provided, the Holder or
holder of a share of Common Stock then outstanding as to which such
restrictions have terminated shall be entitled to receive from the Company,
without expense to such holder, one or more new certificates for the Warrant
or for such shares of Common Stock not bearing any restrictive legend.

                 (d)  Financial Risk. The Holder has such knowledge and
experience in financial and business matters as to be capable of evaluating
the merits and risks of its investment, and has the ability to bear the
economic risks of its investment.

                                       7
<PAGE>

                 (e)  Risk of No Registration. The Holder understands that if
the Company does not register with the Securities and Exchange Commission
pursuant to Section 12 of the 1933 Act, or file reports pursuant to Section
15(d), of the Securities Exchange Act of 1934 (the "1934 Act"), or if a
registration statement covering the securities under the 1933 Act is not in
effect when it desires to sell (i) the Warrant, or (ii) the Common Stock
issuable upon exercise of the Warrant, it may be required to hold such
securities for an indefinite period. The Holder also understands that any sale
of the Warrant or the Common Stock issuable upon exercise of the Warrant which
might be made by it in reliance upon Rule 144 under the 1933 Act may be made
only in accordance with the terms and conditions of that Rule.

                 (f)  Accredited Investor. Holder is an "accredited investor"
within the meaning of Rule 501 of Regulation D under the 1933 Act, as
presently in effect.

       11.  Modification and Waiver. This Warrant and any provision hereof may
be changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

       12.  Notices. Any notice, request or other document required or
permitted to be given or delivered to the holder hereof or the Company shall
be delivered or shall be sent by certified mail, postage prepaid, to each such
holder at its address as shown on the books of the Company or to the Company
at the address indicated therefor in the first paragraph of this Warrant or
such other address as either may from time to time provide to the other.

       13.  Binding Effect on Successors. This Warrant shall be binding upon
any corporation succeeding the Company by merger, consolidation or acquisition
of all or substantially all of the Company's assets. All of the obligations of
the Company relating to the Common Stock issuable upon the exercise of this
Warrant shall survive the exercise and termination of this Warrant. All of the
covenants and agreements of the Company shall inure to the benefit of the
successors and assigns of the holder hereof.

       14.   Market Standoff Agreement. In connection with the initial public
offering of the Company's securities and upon request of the Company or the
underwriters managing such offering of the Company's securities, the Holder
agrees not to sell, make any short sale of, loan, grant any option for the
purchase of, or otherwise dispose of any securities of the Company (other than
those included in the registration) without the prior written consent of the
Company or such underwriters, as the case may be, for such period of time (not
to exceed 180 days) from the effective date of such registration as may be
requested by the Company or such managing underwriters and to execute an
agreement reflecting the foregoing as may be requested by the underwriters at
the time of the Company's initial public offering; provided that all then-
current officers and directors of the Company are similarly restricted. In
order to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the securities of the Holder. The Holder agrees
that prior to the Company's initial public offering it will not transfer
securities of the Company unless each transferee agrees in writing to be bound
by all of the provisions of this Section 14.

                                       8

       15.  Descriptive Headings and Governing Law. The description headings
of the several sections and paragraphs of this Warrant are inserted for
convenience only and do not constitute a part of this Warrant. This Warrant
shall be construed and enforced in accordance with, and the rights of the
parties shall be governed by, the laws of California.

       16.  Lost Warrants. The Company represents and warrants to the Holder
hereof that upon receipt of evidence reasonably satisfactory to the Company of
the loss, theft, destruction, or mutilation of this Warrant and, in the case
of any such loss, theft or destruction, upon receipt of an indemnity
reasonably satisfactory to the Company, or in the case of any such mutilation
upon surrender and cancellation of such Warrant, the Company, at its expense,
will make and deliver a new Warrant, of like tenor, in lieu of the lost,
stolen, destroyed or mutilated Warrant.

       17.  Fractional Shares. No fractional shares shall be issued upon
exercise of this Warrant. The Company shall, in lieu of issuing any fractional
share, pay the holder entitled to such fraction a sum in cash equal to such
fraction multiplied by the then effective Exercise Price.

                             EMPLOYMENT AGREEMENT



          This AGREEMENT is entered into as of October 5, 1999, by and between
Alfred J. Amoroso (the "Executive") and CrossWorlds Software, Inc., a Delaware
corporation (the "Company").

          1.  Duties and Scope of Employment.
              ------------------------------

                  (a)  Position. For the term of his employment under this
                       --------
Agreement ("Employment"), the Company agrees to employ the Executive in the
position of President and Chief Executive Officer. The Executive shall report to
the Company's Board of Directors. At the next meeting of the Board of Directors,
the Executive will be nominated to serve as a Director, and if so elected, the
Executive shall serve in such capacity without additional compensation.

                  (b)  Obligations to the Company. During the term of his
                       --------------------------
Employment, the Executive shall devote his full business efforts and time to the
Company; provided, however, that after the first year of Employment with the
Company this shall not preclude the Executive from serving as a member of the
board of directors of up to three other companies to the extent such other
companies do not compete with the Company and to the extent such service does
not materially impact the ability of the Executive to fulfill his obligations to
the Company. During the first year of Employment, the Executive may serve as a
member of the board of directors of other companies only with the written
consent of the Board of Directors of the Company. The Executive shall comply
with the Company's policies and rules, as they may be in effect from time to
time during the term of his Employment.

                  (c)  No Conflicting Obligations. The Executive represents and
                       --------------------------
warrants to the Company that he is under no obligations or commitments, whether
contractual or otherwise, that are inconsistent with his obligations under this
Agreement. The Executive represents and warrants that he will not use or
disclose, in connection with his employment by the Company, any trade secrets or
other proprietary information or intellectual property in which the Executive or
any other person has any right, title or interest and that his employment by the
Company as contemplated by this Agreement will not infringe or violate the
rights of any other person or entity. The Executive represents and warrants to
the Company that he has returned all property and confidential information
belonging to any prior employers.

                  (d)  Commencement Date.  The Executive shall commence full-
                       -----------------
time Employment on October __, 1999.

          2.  Cash and Incentive Compensation.
              -------------------------------

                  (a)  Salary.  The Company shall pay the Executive as
                       ------
compensation for his services a base salary at the rate of not less than
$41,666.66 per month, payable in accordance
<PAGE>

with the Company's standard payroll schedule. (The compensation specified in
this Subsection (a), together with any increases in such compensation that the
Company may grant from time to time, is referred to in this Agreement as "Base
Salary.")

                  (b)  Sign-on Bonus. The Executive shall be paid a sign-on
                       -------------
bonus of $400,000, less all applicable deductions, that will be earned when
Executive commences Employment. This bonus will be paid on or before March 1,
2000.

                  (c)  Target Bonus. The Executive will be paid a pro rata
                       ------------
target bonus for the period ending December 31, 1999 based on the number of
weeks of actual employment in 1999 and a full annual target bonus of $250,000;
this bonus will be paid on or before March 1, 2000. Executive will be paid a
bonus of $250,000 for calendar year 2000; this payment will be made on or before
February 15, 2001. Beginning with the year 2001 and for each year thereafter
during the Employment Period, the Executive will be eligible to earn an annual
bonus (the "Bonus") equal to at least fifty percent (50%) of his Base Salary
based on his achievement of objective or subjective criteria established by the
Company's Board after consultation with Executive. Unless otherwise provided in
this paragraph (c), any bonus payable hereunder shall be payable annually in
accordance with the Company's normal practices and policies.

                  (d)  Stock Options.
                       -------------

                         (i)  Option Grant. Subject to the approval of the
                              ------------
Company's Board of Directors, the Company shall grant the Executive a stock
option to purchase 1,328,245 shares of the Company's common stock, which after
including the stock option grant described in Subsection (ii) below, represents
8% of the Company's outstanding fully diluted common stock immediately following
such stock grant (including common shares and assumed conversion into common
stock of all series of preferred shares, warrants, options and shares available
for option grants and giving effect to the Company's Series F Preferred stock
financing and related one for three reverse stock split). Such option shall be
granted as soon as reasonably practicable after the date Executive's Employment
commences. The per share exercise price of the option will be equal to the per
share fair market value of the common stock on the date of grant, as determined
by the Board of Directors. The term of such option shall be 10 years, subject to
earlier expiration in the event of the termination of the Executive's
Employment. Such option shall be immediately exercisable, if Executive elects to
do so, but the purchased shares shall be subject to repurchase by the Company at
the exercise price in the event that the Executive's Employment terminates
before he vests in the shares. The Executive shall vest, and the Company's
repurchase right if applicable shall lapse in the option shares in equal monthly
installments over forty-eight (48) months from the date Executive's Employment
commences.

                         (ii) Option Grant. Subject to the approval of the
                              ------------
Company's Board of Directors, the Company shall grant the Executive a stock
option to purchase 796,947 shares of the Company's common stock, which after
including the stock option grant described in Subsection (i) above, represents
8% of the Company's outstanding fully diluted common stock immediately following
such stock grant (including common shares and assumed conversion into common
stock of all series of preferred shares, warrants, options and shares available
for option grants and giving effect to the Company's Series F Preferred stock
financing and related one for

                                       2
<PAGE>

three reverse stock split). Such option shall be granted as soon as reasonably
practicable after the date Executive's Employment commences. The per share
exercise price of the option will be equal to the per share fair market value of
the common stock on the date of grant, as determined by the Board of Directors.
The term of such option shall be 10 years, subject to earlier expiration in the
event of the termination of the Executive's Employment. Such option shall be
immediately exercisable, if Executive elects to do so, but the purchased shares
shall be subject to repurchase by the Company at the exercise price in the event
that the Executive's Employment terminates before he vests in the shares. The
Executive shall vest in the option shares, and the Company's repurchase right if
applicable shall lapse, in equal monthly installments over forty-eight (48)
months from the date Executive's Employment commences; however, the vesting
shall accelerate and the Company's repurchase right, if applicable, will lapse
immediately upon the effective date of an initial public offering of the
Company's stock.

                         (iii)  Exercise of Options. The option grants made
                                -------------------
pursuant to subsections (i) and (ii) above shall be subject to the Company's
standard form of stock option agreements, copies of each of which are attached
hereto as exhibits and must be executed as a condition of the grant and
exercise. Executive shall have the right to exercise his options while he
remains employed by the Company by delivering a full recourse promissory note
secured by a pledge of the shares purchased thereunder. If required under the
laws of the Company's state of incorporation, Executive shall pay cash for the
par value of the exercised option shares. Interest on the promissory note shall
accrue at the minimum applicable federal rate under the Internal Revenue Code to
avoid imputed income. The principal balance and interest shall be due in full on
the earlier of the fourth anniversary of Executive's hire date or 90 days after
the termination of Executive's Employment. The note shall be subject to such
other terms and conditions as may be agreed to by the Company and Executive. The
credit extended to Executive hereunder shall equal the aggregate option price
payable for the purchased shares.

                         (iv) Registration of Shares. The Company will take all
                              ----------------------
reasonable steps at its sole cost and expense to register Executive's stock
following an initial public offering so that Executive can sell any vested
shares of stock if he so chooses following the expiration of any applicable
lock-up period. Nothing herein will be interpreted as requiring the Company to
breach any rights regarding the registration of securities under the Securities
Act of 1933.

                         (v)  Effect of Termination of Employment. If during the
                              -----------------------------------
first year of Executive's Employment, the Company terminates Executive's
Employment "Without Cause" or Executive resigns for "Good Reason," then fifty
percent (50%) of the shares subject to Executive's outstanding options will
become vested and, if applicable, the Company's repurchase rights as to such
shares will lapse. Following the first year of Executive's Employment, if the
Company terminates Executive's Employment "Without Cause," or Executive resigns
for "Good Reason," then Executive shall receive additional vesting of all of his
outstanding options and, if applicable, the Company's repurchase rights as to
such shares will lapse, as if he had provided an additional twelve (12) months
of service from the date employment terminates.

                         (vi) Effect of Change of Control. In the event of a
                              ---------------------------
Change of Control during the period of Executive's employment, then each of
Executive's outstanding

                                       3
<PAGE>

options will become fully vested and, if applicable, the Company's repurchase
rights will lapse as to all shares subject to all options.

                         (vii)  Definitions.
                                -----------

                             (a)   "Change of Control." For all purposes under
                                    -------------------
this Agreement, "Change of Control" shall mean (i) a merger or consolidation in
which securities possessing at least fifty percent (50%) of the total combined
voting power of the Corporation's outstanding securities are transferred to a
person or persons different from the persons holding those securities
immediately prior to such transaction, or (ii) the sale, transfer or other
disposition of all or substantially all of the Corporation's assets in complete
liquidation or dissolution of the Corporation.

                             (b)   "Good Reason." For all purposes under this
                                   --------------
Agreement, "Good Reason" for Executive's resignation will exist if he resigns
within sixty days of any of the following: (i) any reduction in his base salary
or target bonus; (ii) any material reduction in his benefits; (iii) a change in
his position with the Company or a successor company which materially reduces
his duties or level of responsibility; or (iv) any requirement that he relocate
his place of employment by more than thirty-five (35) miles from his then
current office, provided such reduction, change or relocation is effected by the
Company without his written consent. A resignation by Executive under any other
circumstances or for any other reasons will be a resignation "Without Good
Reason."

                             (c)   Termination for "Cause." For all purposes
                                   ------------------------
under this Agreement, a termination for "Cause" shall mean a good faith
determination by the Company's Board of Directors that Executive's Employment be
terminated for any of the following reasons: (i) willful misconduct which
materially damages the Company; (ii) misappropriation of the assets of the
Company; or (iii) conviction of, or a plea of "guilty" or "no contest" to, a
felony under the laws of the United States or any state thereof. A termination
of Executive's Employment in any other circumstances or for any other reasons
will be a termination "Without Cause."

          3.  Vacation and Executive Benefits. During the term of his
              -------------------------------
Employment, the Executive shall be eligible for paid vacation in accordance with
the Company's standard policy for similarly situated employees, as it may be
amended from time to time. During the term of his Employment, the Executive
shall be eligible to participate in any employee benefit plans maintained by the
Company for similarly situated employees, subject in each case to the generally
applicable terms and conditions of the plan in question and to the
determinations of any person or committee administering such plan.

          4.  Business Expenses. During the term of his Employment, the
              -----------------
Executive shall be authorized to incur necessary and reasonable travel,
entertainment and other business expenses in connection with his duties
hereunder. The Company shall reimburse the Executive for such expenses upon
presentation of an itemized account and appropriate supporting documentation,
all in accordance with the Company's generally applicable policies.

                                       4
<PAGE>

          5.  Real Estate Assistance. The Company will provide the Executive
              ----------------------
with a moving assistance loan (the "Loan") of $1,500,000 to assist the Executive
in moving into a home similar to that in which he presently resides. This Loan
will be provided within a reasonable time after Executive commences employment.
In order to receive this Loan, Executive will be required to execute a non-
recourse promissory note (the "Note") secured by Executive's real estate or
other collateral acceptable to the Company. The Note will bear interest at the
minimum applicable federal rate under the Internal Revenue Code to avoid the
imputation of income. The principal amount of the Loan and accrued interest are
due and payable on the earlier of (i) nine months after the date Executive's
Employment terminates, or (ii) the date when Executive's home is sold. However,
the principal amount of the Loan and accrued interest will be forgiven in equal
monthly installments on the last day of each month from the date of employment
for a period of forty-eight (48) months, provided the Executive remains employed
through each such date. The Company will make periodic bonus payments to
Executive which, following the deduction of all applicable taxes, will allow
Executive to make all tax payments on the loan and forgiven interest. If prior
to the fourth anniversary of the date Executive commences Employment the Company
terminates Executive's Employment "Without Cause" or Executive resigns for "Good
Reason," then on the termination date the Company shall forgive Executive's
monthly installment payments of the loan and accrued interest for twelve (12)
additional months as if Executive had been employed by the Company for those
twelve additional months.

          6.  Relocation and Temporary Living Expenses.
              ----------------------------------------

                  (a)  Relocation Assistance. The Company will provide the
                       ---------------------
Executive with full relocation assistance including payment of all closing costs
on the sale of Executive's current home plus all acquisition costs on the
purchase of his new home in the Bay Area. The Company also will pay for the
packing and unpacking of his household goods, relocation of his household goods
and two house hunting trips including business class airfare from Tokyo, Japan
to the Bay Area for Executive, his spouse and dependent child. The Company
agrees to pay for the relocation of household goods from the Executive's
temporary residence in Tokyo to either Connecticut or California, as Executive
deems necessary, and from Executive's current home in Connecticut to a new home
in California. The Executive shall present appropriate supporting documentation
of such costs in accordance with the Company's generally applicable policies.

                  (b)  Temporary Living Expenses. The Company also will pay for
                       -------------------------
Executive's temporary living costs to make Executive whole until such time as
the Executive, his spouse and dependent children permanently relocate to the Bay
Area. The Executive shall present appropriate supporting documentation of such
costs in accordance with the Company's generally applicable policies. The
Company and Executive agree that such costs cannot be fully anticipated at this
time, but may total $200,000 to $300,000, and may include, but are not limited
to, the following: (a) a monthly housing allowance for rental of a furnished
apartment for Executive's family in Tokyo, Japan; (b) a monthly housing
allowance for Executive's rental of temporary housing in the Bay Area; (c)
tuition and related educational fees for Executive's dependent son; (d) monthly
support for Executive's spouse and dependent child in Tokyo, Japan through
Relocation Services; and (e) reimbursement for two roundtrip business class
airfares per month for either Executive to return to Tokyo, Japan or Executive's
spouse and dependent child to travel to the Bay Area. The Executive will book
such travel arrangements as far in advance as

                                       5
<PAGE>

practicable to minimize the expense of such airfare, and make all possible
efforts to consolidate business travel with trips to Tokyo. In the event there
are additional unanticipated temporary living expenses, the Company will
evaluate in good faith payment of such expenses with the intent to make the
Executive whole.

                  (c)  Gross-up. The Company will provide Executive a gross-up
                       --------
on payments for relocation and temporary living expenses that are not deductible
for tax purposes.

superseded by this Agreement. This Agreement shall constitute the full and
complete agreement between the Executive and the Company on the "at will" nature

reimbursements described in Sections 2, 3 and 4 for the period preceding the

Unless otherwise defined herein, the terms defined in the Plan shall have the

   b.  Exercise of Option.  This Option shall be exercisable during its term in
       ------------------
accordance with the Vesting Schedule set out in the Notice of Grant and with the
provisions of Section 9 of the Plan as follows:

      (i) Right to Exercise.  (a) This Option may be exercised in whole or in
          -----------------
part at any time after the Date of Grant, as to Shares which have not yet vested
under the vesting schedule indicated on the Notice of Stock Option Grant;

provided, however, that Optionee shall execute as a condition to such exercise
- --------  -------
of this Option, the Early Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit A (the "Early Exercise Agreement").  If
                             ---------       ------------------------
Optionee chooses to exercise this Option solely as to Shares which have vested
under the vesting schedule indicated on the Notice of Stock Option Grant,
Optionee shall complete and execute the form of Exercise Notice attached hereto
as Exhibit B (the "Exercise Agreement").  Notwithstanding the foregoing, the
   ---------       ------------------
Company may in its discretion prescribe or accept a different form of notice of
exercise and/or stock purchase agreement if such forms are otherwise consistent
with this Agreement, the Plan and then-applicable law.  (b) This Option may not
be exercised for a fraction of a Share. (c) In the event of Optionee's death,
Disability or other termination of the Optionee's Continuous Status as an
Employee, Consultant or Director, the exercisability of the Option is governed
by Sections g, h and i below, subject to the limitation contained in Section k.
below.  (d) In no event may this Option be exercised after the date of
expiration of the term of this Option as set forth in the Notice of Grant.

      (ii) Method of Exercise.  This Option shall be exercisable by execution
           ------------------
and delivery of the Early Exercise Agreement or the Exercise Agreement,
whichever is applicable, or of any other written notice approved for such
purpose by the Company which shall state the election to exercise the Option,
the number of Shares in respect of which the Option is being exercised, and such
other representations and agreements as to the holder's investment intent with
respect to such shares of Common Stock as may be required by the Company
pursuant to the provisions of the Plan.  Such written notice shall be signed by
the Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The written notice shall be accompanied by payment of
the Exercise Price.  This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

      No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of law and
the requirements of any stock exchange or national market system upon which the
Common Stock is then listed.  Assuming such compliance, for income tax purposes
the Shares shall be considered transferred to the Optionee on the date on which
the Option is exercised with respect to such Shares.

   c.  Optionee's Representations.  In the event the Shares purchasable pursuant
       --------------------------
to the exercise of this Option have not been registered under the Securities Act
of 1933, as amended, at the time this Option is exercised, Optionee shall, if
required by the Company, concurrently with the exercise of all or any portion of
this Option, deliver to the Company his or her Investment Representation
Statement in the form attached hereto as Exhibit C.

   d.  Lock-Up Period.  Optionee hereby agrees that if so requested by the
       --------------
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
longer period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act; provided, however, that such restriction shall apply only  to
the first registration statement of the Company to become effective under the
Securities Act that includes securities to be sold on behalf of the Company to
the public in an underwritten public offering under the Securities Act.  The
Company may impose stop-transfer instructions with respect to securities subject
to the foregoing restrictions until the end of such Market Standoff Period.

   e.  Method of Payment.  Payment of the Exercise Price shall be by any of the
       -----------------
following, or a combination thereof, at the election of the Optionee:

       (i)   cash; or

       (ii)  check; or

       (iii) surrender of other shares of Common Stock of the Company which (A)
in the case of Shares acquired pursuant to the exercise of a Company option,
have been owned by the Optionee for more than six (6) months on the date of
surrender, and (B) have a Fair Market Value on the date of surrender equal to
the Exercise Price of the Shares as to which the Option is being exercised; or

       (iv)  to the extent authorized by the Company, delivery of a properly
executed exercise notice together with such other documentation as the
Administrator and the broker, if applicable, share require to effect an exercise
of the Option and delivery to the Company of the sale or loan proceeds required
to pay the Exercise Price; or

       (v)   promissory note (in the form provided by the Company).

   f.  Restrictions on Exercise.  This Option may not be exercised if the
       ------------------------
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the
Federal Reserve Board.  As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

   g.  Termination of Relationship.  In the event an Optionee's Continuous
       ---------------------------
Status as an Employee, Consultant or Director terminates, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "Termination
Date"), exercise this Option during the Termination Period set out in the Notice
of Grant.  To the extent that Optionee was not entitled to exercise this Option
at the date of such termination, or if Optionee does not exercise this Option
within the time specified herein, the Option shall terminate.

   h.  Disability of Optionee.  Notwithstanding the provisions of Section g.
       ----------------------
above, in the event of termination of an Optionee's Continuous Status as an
Employee, Consultant or Director as a result of his or her Disability, Optionee
may, but only within twelve (12) months from the date of such termination (and
in no event later than the expiration date of the term of such Option as set
forth in the Notice of Grant) exercise the Option to the extent otherwise
entitled to exercise it at the date of such termination.  To the extent that
Optionee is not entitled to exercise the Option at the date of termination, or
if Optionee does not exercise such Option to the extent so entitled within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

   i.  Death of Optionee.  In the event of termination of Optionee's Continuous
       -----------------
Status as an Employee or Consultant as a result of the death of Optionee, the
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the date of expiration of the term of this
Option as set forth in Section k. below), by Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent the Optionee could exercise the Option at the date of death.

   j.  Non-Transferability of Option.  Options may not be sold, pledged,
       -----------------------------
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.  The terms of this Option shall
be binding upon the executors, administrators, heirs, successors and assigns of
the Optionee.

   k.  Term of Option.  This Option may be exercised only within the term set
       --------------
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.  The limitations set out
in Section 7 of the Plan regarding Options granted to more than ten percent
(10%) shareholders shall apply to this Option.

   l.  Tax Consequences.  Set forth below is a brief summary as of the date of
       ----------------
this Option of some of the federal tax consequences of exercise of this Option
and disposition of the Shares.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE
TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

      (i) Exercise of an NSO.  There may be a regular federal income tax
          ------------------
liability upon the exercise of an NSO.  The Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price.  In the case of the exercise of Option Shares which
have not vested as of the date of exercise, the Optionee will not realize
compensation income on the exercise until the date(s) on which shares vest
(i.e., have been released from the Company's repurchase option) unless the
Optionee files an election under Section 83(b) of the Code (an "83(b)
Election").  If an 83(b) election is filed, the amount of compensation income
will be determined on the date of exercise.  If Optionee is an Employee, the
Company will be required to withhold from Optionee's compensation or collect
from Optionee and pay to the applicable taxing authorities an amount equal to a
percentage of this compensation income at the time of exercise or vesting, as
applicable.

      (ii) Disposition of Shares.  If Shares are held for more than one year
           ---------------------
after the date of exercise (or the date of vesting, if later, in the case of the
exercise of unvested option shares and the Optionee had not filed an 83(b)
election at the time of such exercise, any gain realized on disposition of the
Shares will be treated as long-term capital gain for federal income tax
purposes.

               EARLY EXERCISE NOTICE AND STOCK PURCHASE AGREEMENT


CrossWorlds Software, Inc.
577 Airport Boulevard, Suite 800
Burlingame, CA  94010-2024
Attention: Stock Administrator

     1.  Exercise of Option.  Effective as of today, ___________, _____, the
         ------------------
undersigned ("Purchaser") __________________ hereby elects to exercise
Purchaser's option to purchase _________ shares of the Common Stock (the
"Shares") of CrossWorlds Software, Inc. (the "Company") under and pursuant to
the CrossWorlds Software , Inc., 1999 Executive Stock Plan, as amended (the
"Plan") and the Stock Option  Agreement dated _____________________________ (the
"Option Agreement").  Of these Shares, Purchaser has elected to purchase
_______________ of those Shares which have become vested as of the date hereof
under the Vesting Schedule set forth in the Notice of Stock Option Grant (the

"Vested Shares") and _____________ Shares which have not yet vested under such
- --------------
Vesting Schedule (the "Unvested Shares").  The purchase price for the Shares
                       ---------------
shall be $______ per Share for a total purchase price of $_______________.
The term "Shares" refers to the purchased Shares and all
          ------
securities received in replacement of the Shares or as stock dividends or
splits, all securities received in replacement of the Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of the Shares.

     2.  Representations of Purchaser.  Purchaser acknowledges that Purchaser
         ----------------------------
has received, read and understood the Plan and the Option Agreement and agrees
to abide by and be bound by their terms and conditions.

     3.  Rights as Stockholder.  Until the stock certificate evidencing such
         ---------------------
Shares is issued (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a stockholder shall exist with
respect to the Optioned Stock, notwithstanding the exercise of the Option.  The
Company shall issue (or cause to be issued) such stock certificate promptly
after the Option is exercised.  No adjustment will be made for a dividend or
other right for which the record date is prior to the date the stock certificate
is issued, except as provided in Section 12 of the Plan.

          Purchaser shall enjoy rights as a stockholder until such time as
Purchaser disposes of the Shares or the Company and/or its assignee(s) exercises
the Right of First Refusal hereunder.  Upon such exercise, Purchaser shall have
no further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser shall forthwith cause the certificate(s)
evidencing the Shares so purchased to be surrendered to the Company for transfer
or cancellation.

     4.  Limitations on Transfer.  In addition to any other limitation on
         -----------------------
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares while the Shares are subject
to the Company's Repurchase Option (as defined below).  After any Shares have
been released from such Repurchase Option, Purchaser shall not assign, encumber
or dispose of any interest in such Shares except in compliance with the
provisions below and applicable securities laws.

          (a)  Repurchase Option.
               -----------------

               (i) If Purchaser's Continuous Status as an Employee or Consultant
terminates for any reason (including for cause, death or disability), the
Company shall upon the date of such termination (the "Termination Date") have an
                                                      ----------------
irrevocable, exclusive option (the "Repurchase Option") for a period of 60 days
                                    -----------------
from such date to repurchase all or any portion of the Unvested Shares held by
Purchaser as of the Termination Date which have not yet been released from the
Company's Repurchase Option at the original purchase price per Share specified
in Section 1 (adjusted for any stock splits, stock dividends and the like).

               (ii) The Repurchase Option shall be exercised by the Company by
written notice to Purchaser or Purchaser's executor and, at the Company's
option, (A) by delivery to Purchaser or Purchaser's executor with such notice of
a check in the amount of the purchase price for the Shares being purchased, or
(B) in the event Purchaser is indebted to the Company, by cancellation by the
Company of an amount of such indebtedness equal to the purchase price for the
Shares being repurchased, or (C) by a combination of (A) and (B) so that the
combined payment and cancellation of indebtedness equals such purchase price.
Upon delivery of such notice and payment of the purchase price in any of the
ways described above, the Company shall become the legal and beneficial owner of
the Shares being repurchased and all rights and interest therein or related
thereto, and the Company shall have the right to transfer to its own name the
number of Shares being repurchased by the Company, without further action by
Purchaser.

               (iii)  One hundred percent (100%) of the Unvested Shares shall
initially be subject to the Repurchase Option.  The Unvested Shares shall be
released from the Repurchase Option in accordance with the Vesting Schedule set
forth in the Notice of Stock Option Grant
<PAGE>

until all Shares are released from the Repurchase Option. Fractional shares
shall be rounded to the nearest whole share.

          (b) Company's Right of First Refusal.  Before any Shares held by
              --------------------------------
Purchaser or any transferee (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section (the "Right of First Refusal").

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

               (ii)  Exercise of Right of First Refusal.  At any time within
                     ----------------------------------
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

               (iii) Purchase Price. The purchase price ("Purchase Price") for
                     --------------
the Shares purchased by the Company or its assignee(s) under this Section shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

               (iv)  Payment.  Payment of the Purchase Price shall be made, at
                     -------
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

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

               (vi) Exception for Certain Family Transfers.  Anything to the
                    --------------------------------------
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Purchaser's lifetime or on the Purchaser's death by
will or intestacy to the Purchaser's immediate family or a trust for the benefit
of the Purchaser's immediate family shall be exempt from the provisions of this
Section. "Immediate Family" as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister. In such case, the transferee
or other recipient shall receive and hold the Shares so transferred subject to
the provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

               (vii) Termination of Right of First Refusal.  The Right of First
                     -------------------------------------
Refusal shall terminate as to any Shares 90 days after the (i) first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the Securities and Exchange
Commission under the Securities Act of 1933, as amended, or (ii) a merger of the
Company with a corporation whose stock is publicly traded on a national
exchange.

     5.  Transfer of Shares; Escrow.
         --------------------------

         (a) Purchaser hereby authorizes and directs the Secretary of the
Company, or such other person designated by the Company, to transfer any
Unvested Shares as to which the Repurchase Option has been exercised from
Purchaser to the Company.

         (b) To ensure the availability for delivery of Purchaser's Unvested
Shares upon repurchase by the Company pursuant to the Repurchase Option under
Section 4(a), Purchaser hereby appoints Katrina A. Garnett of the Company, or
any other person designated by the Company, as escrow agent (the "Escrow Agent")
                                                                  ------------
and as Purchaser's attorney-in-fact to sell, assign and transfer unto the
Company such Unvested Shares, if any, as may be repurchased by the Company
pursuant to the Repurchase Option and shall, upon execution of this Agreement,
deliver and deposit with the Escrow Agent the share certificates representing
the Unvested Shares, together with two stock assignments duly endorsed in blank
and in the form attached hereto as Attachment A .  The Unvested Shares and stock
                                   ------------
assignment shall be held by the Escrow Agent in escrow pursuant to Joint Escrow
Instructions in the form attached hereto as Attachment B , until (i) the Company
                                            ------------
exercises its Repurchase Option as provided in Section 4(a), (ii) such Unvested
Shares become Vested Shares, or (iii) such time as this Agreement no longer is
in effect.  Upon vesting of the Unvested Shares, the Escrow Agent shall promptly
deliver to Purchaser the certificate or certificates representing such Shares in
the Escrow Agent's
<PAGE>

possession belonging to Purchaser, and the Escrow Agent shall be discharged of
all further obligations hereunder. Notwithstanding any of the foregoing,
however, the Escrow Agent shall nevertheless retain such certificate or
certificates as Escrow Agent if so required pursuant to other restriction
imposed pursuant to this Agreement.

          (c) The Escrow Agent shall not be liable for any act it may do or omit
to do with respect to holding the Shares in escrow and while acting in good
faith and in the exercise of its judgment.

          (d) Transfer or sale of the Shares is subject to restrictions on
transfer imposed by any applicable state and federal securities laws.  Any
transferee shall hold such Shares subject to all the provisions hereof and shall
acknowledge the same by signing a copy of this Agreement.

          (e) No Shares may be sold, pledged, hypothecated or otherwise
transferred by Purchaser until such Shares have become Vested Shares and are no
longer subject to any security agreement for the benefit of the Company.

     6.   Ownership, Voting Rights, Duties.  This Agreement shall not affect in
          --------------------------------
any way the ownership, voting rights or other rights or duties of Purchaser,
except as specifically provided herein.  Purchaser shall enjoy rights as a
stockholder until such time as Purchaser disposes of the Shares or the Company
and/or its assignee(s) exercises either the Repurchase Option or the Right of
First Refusal hereunder.  Upon any such exercise, Purchaser shall have no
further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser or the Escrow Agent, as the case may be, shall
forthwith cause the certificate(s) evidencing the Shares so purchased to be
surrendered to the Company for transfer or cancellation.

     7.   Tax Consultation.  Purchaser understands that Purchaser may suffer
          ----------------
adverse tax consequences as a result of Purchaser's purchase or disposition of
the Shares.  Purchaser represents that Purchaser has consulted with any tax
consultants Purchaser deems advisable in connection with the purchase or
disposition of the Shares and that Purchaser is not relying on the Company for
any tax advice.

     8.   Restrictive Legends; Stop-Transfer Orders; Market Standoff
          ----------------------------------------------------------

          (a) Legends.  Purchaser understands and agrees that the Company shall
              -------
cause the legends set forth below or legends substantially equivalent thereto,
to be placed upon any certificate(s) evidencing ownership of the Shares together
with any other legends that may be required by the Company or by state or
federal securities laws:

              THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
              THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
              SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
              UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY
              COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH
              OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
              THEREWITH.

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

          (b) Stop-Transfer Notices.  Purchaser agrees that, in order to ensure
              ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company  transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (c) Market Standoff.  Purchaser hereby agrees that if so requested by
              ---------------
the Company or any representative of the underwriters in connection with any
registration of the offering of any securities of the Company under the
Securities Act of 1933, as amended (the "Securities Act"), neither Purchaser nor
                                         --------------
Purchaser shall sell or otherwise transfer any Shares or other securities of the
Company during such period as the Company and the representatives of the
underwriters may request (not to exceed 180 days) following the effective date
of any registration statement of the Company filed under the Securities Act for
an underwritten public offering. The Company may impose stop-transfer
instructions with respect to Shares subject to the foregoing restrictions until
the end of such market standoff period.

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

     9.  Section 83(b) Election.  Purchaser understands that Section 83(a) of
         ----------------------
the Internal Revenue Code of 1986, as amended (the
<PAGE>

"Code"), taxes as ordinary income for a [Nonstatutory] [Incentive] Stock Option
the difference between the amount paid for the Shares and the Fair Market Value
of the Shares as of the date any restrictions on the Shares lapse. In this
context, "restriction" means the right of the Company to buy back the Shares
          -----------
pursuant to the Repurchase Option set forth in Section 4(a) of this Agreement.
Purchaser understands that Purchaser may elect to be taxed at the time the
Shares are purchased, rather than when and as the Repurchase Option expires, by
filing an election under Section 83(b) (an "83(b) Election") of the Code with
                                            --------------
the Internal Revenue Service within 30 days from the date of purchase. Even if
the Fair Market Value of the Shares at the time of the execution of this
Agreement equals the amount paid for the Shares, the election must be made to
avoid income tax treatment under Section 83(a) in the future. Purchaser
acknowledge that it is Purchaser's sole responsibility and not the Company's to
timely file the 83(b) Election, even if Purchaser requests the Company or its
representative to make this filing on Purchaser's behalf. Purchaser understands
that failure to file such an election in a timely manner may result in adverse
tax consequences for Purchaser. Purchaser further understands that an additional
copy of such election form should be filed with his or her federal income tax
return for the calendar year in which the date of this Agreement falls.
Purchaser acknowledges that the foregoing is only a summary of the effect of
United States federal income taxation with respect to purchase of the Shares
hereunder, and does not purport to be complete. Purchaser further acknowledges
that the Company has directed Purchaser to seek independent advice regarding the
applicable provisions of the Code, the income tax laws of any municipality,
state or foreign country in which Purchaser may reside, and the tax consequences
of Purchaser's death.

          Purchaser agrees that he or she will execute and deliver to the
Company with this executed Agreement a copy of the Acknowledgment and Statement
of Decision Regarding Section 83(b) Election (the "Acknowledgment") attached
                                                   --------------
hereto as Attachment C.  Purchaser further agrees that he or she will execute
          ------------
and submit with the Acknowledgment a copy of the 83(b) Election attached hereto
as Attachment D (for tax purposes in connection with the early exercise of an
   ------------
option) if Purchaser has indicated in the Acknowledgment his or her decision to
make such an election.

     10.  Notices.  All notices and other communications required or permitted
          -------
hereunder shall be in writing, shall be effective when given, and shall in any
event be deemed to be given (a) five (5) days after the deposit with the U.S.

Sand Hill Road, Menlo Park, California 94025, Attention:  Jon E. Gavenman, Esq.,

as the Escrow Agent shall have furnished to the parties.

     11.  Successors and Assigns.  The Company may assign any of its rights
          ----------------------
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company.  Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Purchaser and his or her heirs, executors, administrators, successors and
assigns.

     12.  Interpretation.  Any dispute regarding the interpretation of this
          --------------
Agreement shall be submitted by Purchaser or by the Company forthwith to the
Company's Board of Directors or the committee thereof that administers the Plan,
which shall review such dispute at its next regular meeting.  The resolution of
such a dispute by the Board or committee shall be final and binding on the
Company and on Purchaser.

     13.  Governing Law; Severability.  This Agreement shall be governed by and
          ---------------------------
construed in accordance with the laws of the State of California excluding that
body of law pertaining to conflicts of law.  Should any provision of this
Agreement be determined by a court of law to be illegal or unenforceable, the
other provisions shall nevertheless remain effective and shall remain
enforceable.

     14.  Notices.  Any notice required or permitted hereunder shall be given in
          -------
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States mail by certified mail, with postage and fees
prepaid, addressed to the other party at its address as shown below beneath its
signature, or to such other address as such party may designate in writing from
time to time to the other party.

     15.  Further Instruments.  The parties agree to execute such further
          -------------------
instruments and to take such further action as may be reasonably necessary to
carry out the purposes and intent of this Agreement.

     16.  Delivery of Payment.  Purchaser herewith delivers to the Company the
          -------------------
full Exercise Price for the Shares.
<PAGE>

     17.  Entire Agreement.  The Plan and Notice of Grant/Option Agreement are
          ----------------
incorporated herein by reference.  This Agreement, the Plan, the Option
Agreement and the Investment Representation Statement constitute the entire
agreement of the parties with respect to the subject matter hereof and supersede
in their entirety all prior undertakings and agreements of the Company and
Purchaser with respect to the subject matter hereof, and may not be modified
adversely to the Purchaser's interest except by means of a writing signed by the
Company and Purchaser.

Purchaser shall sell or otherwise transfer any Shares or other securities of the
Company during such period as the Company and the representatives of the
underwriters may request (not to exceed 180 days) following the effective date
of any registration statement of the Company filed under the Securities Act for
an underwritten public offering. The Company may impose stop-transfer
instructions with respect to Shares subject to the foregoing restrictions until
the end of such market standoff period.

             (d) Refusal to Transfer.  The Company shall not be required (i) to
                 -------------------
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser

other provisions shall nevertheless remain effective and shall remain
enforceable.

                      INVESTMENT REPRESENTATION STATEMENT


PURCHASER:   _____________________

COMPANY:     CROSSWORLDS SOFTWARE, INC.

SECURITY:    ___________ shares of Common Stock

AMOUNT:      __________________________________

DATE:        __________________________________


     In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

     (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities.  Purchaser is
acquiring these Securities for investment for Purchaser's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

     (b) Purchaser acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.  In this connection, Purchaser
understands that, in the view of the Securities and Exchange Commission, the
statutory basis for such exemption may be unavailable if Purchaser's
representation was predicated solely upon a present intention to hold these
Securities for the minimum capital gains period specified under tax statutes,
for a deferred sale, for or until an increase or decrease in the market price of
the Securities, or for a period of one year or any other fixed period in the
future.  Purchaser further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available.  Purchaser further
acknowledges and understands that the Company is under no obligation to register
the Securities.  Purchaser understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities unless they are registered or such registration is not required in
the opinion of counsel satisfactory to the Company and any other legend required
under applicable state securities laws.

     (c) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions.  Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Option to the Purchaser, the exercise will
be exempt from registration under the Securities Act.  In the event the Company
becomes subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer
period as any market stand-off agreement may require) the Securities exempt
under Rule 701 may be resold, subject to the satisfaction of certain of the
conditions specified by Rule 144, including:  (1) the resale being made through
a broker in an unsolicited "broker's transaction" or in transactions directly
with a market maker (as said term is defined under the Securities Exchange Act
of 1934); and, in the case of an affiliate, (2) the availability of certain
public information about the Company, (3) the amount of Securities being sold
during any three month period not exceeding the limitations specified in Rule
144(e), and (4) the timely filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than one year after the later of the date the Securities were
sold by the Company or the date the Securities were sold by an affiliate of the
Company, within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than two years, the satisfaction of the conditions set forth in
sections (1), (2), (3) and (4) of the paragraph immediately above.

     (d) Purchaser hereby agrees that if so requested by the Company or any
representative of the underwriters in connection with any registration of the
offering of any securities of the Company under the Securities Act, Purchaser
shall not sell or otherwise transfer any Shares or other securities of the
Company during the 180-day period following the effective date of a registration
statement of the Company filed under the Securities Act; provided, however, that
such restriction shall only apply to the first registration statement of the
Company to become effective under the Securities Act which include securities to
be sold on behalf of the Company to the public in an underwritten public
offering under the Securities Act.  The Company may impose stop-transfer
instructions with respect to securities subject to the foregoing restrictions
until the end of such 180-day period.
<PAGE>

     (e) Purchaser further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk.  Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

                                               Signature of Purchaser:

                                               ______________________________

1. TERMS AND CONDITIONS OF GRANT

   a.  Grant of Option.  CrossWorlds Software, Inc. (the "Company"), hereby
       ----------------
grants to the Optionee (the "Optionee") named in the Notice of Grant, a
[nonstatutory ][incentive] stock option (the "Option") to purchase the total
number of shares of Common Stock (the Shares") set forth in the Notice of Grant,
at the exercise price per share set forth in the Notice of Grant (the "Exercise
Price") subject to the terms, definitions and provisions of the 1999 Stock Plan
(the "Plan") adopted by the Company, which is incorporated herein by reference.
Unless otherwise defined herein, the terms defined in the Plan shall have the
same defined meanings in this Option Agreement.

   b.  Exercise of Option.  This Option shall be exercisable during its term in
       ------------------
accordance with the Vesting Schedule set out in the Notice of Grant and with the
provisions of Section 9 of the Plan as follows:

      (i) Right to Exercise.  (a) This Option may be exercised in whole or in
          -----------------
part at any time after the Date of Grant, as to Shares which have not yet vested
under the vesting schedule indicated on the Notice of Stock Option Grant;

provided, however, that Optionee shall execute as a condition to such exercise
- --------  -------
of this Option, the Early Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit A (the "Early Exercise Agreement").  If
                             ---------       ------------------------
Optionee chooses to exercise this Option solely as to Shares which have vested
under the vesting schedule indicated on the Notice of Stock Option Grant,
Optionee shall complete and execute the form of Exercise Notice attached hereto
as Exhibit B (the "Exercise Agreement").  Notwithstanding the foregoing, the
   ---------       ------------------
Company may in its discretion prescribe or accept a different form of notice of
exercise and/or stock purchase agreement if such forms are otherwise consistent
with this Agreement, the Plan and then-applicable law.  (b) This Option may not
be exercised for a fraction of a Share. (c) In the event of Optionee's death,
Disability or other termination of the Optionee's Continuous Status as an
Employee, Consultant or Director, the exercisability of the Option is governed
by Sections g, h and i below, subject to the limitation contained in Section k.
below.  (d) In no event may this Option be exercised after the date of
expiration of the term of this Option as set forth in the Notice of Grant.

      (ii) Method of Exercise.  This Option shall be exercisable by execution
           ------------------
and delivery of the Early Exercise Agreement or the Exercise Agreement,
whichever is applicable, or of any other written notice approved for such
purpose by the Company which shall state the election to exercise the Option,
the number of Shares in respect of which the Option is being exercised, and such
other representations and agreements as to the holder's investment intent with
respect to such shares of Common Stock as may be required by the Company
pursuant to the provisions of the Plan.  Such written notice shall be signed by
the Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The written notice shall be accompanied by payment of
the Exercise Price.  This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

      No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of law and
the requirements of any stock exchange or national market system upon which the
Common Stock is then listed.  Assuming such compliance, for income tax purposes
the Shares shall be considered transferred to the Optionee on the date on which
the Option is exercised with respect to such Shares.

   c.  Optionee's Representations.  In the event the Shares purchasable pursuant
       --------------------------
to the exercise of this Option have not been registered under the Securities Act
of 1933, as amended, at the time this Option is exercised, Optionee shall, if
required by the Company, concurrently with the exercise of all or any portion of
this Option, deliver to the Company his or her Investment Representation
Statement in the form attached hereto as Exhibit C.

   d.  Lock-Up Period.  Optionee hereby agrees that if so requested by the
       --------------
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
longer period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act; provided, however, that such restriction shall apply only  to
the first registration statement of the Company to become effective under the
Securities Act that includes securities to be sold on behalf of the Company to
the public in an underwritten public offering under the Securities Act.  The
Company may impose stop-transfer instructions with respect to securities subject
to the foregoing restrictions until the end of such Market Standoff Period.

   e.  Method of Payment.  Payment of the Exercise Price shall be by any of the
       -----------------
following, or a combination thereof, at the election of the Optionee:

       (i)   cash; or

       (ii)  check; or

       (iii) surrender of other shares of Common Stock of the Company which (A)
in the case of Shares acquired pursuant to the exercise of a Company option,
have been owned by the Optionee for more than six (6) months on the date of
surrender, and (B) have a Fair Market Value on the date of surrender equal to
the Exercise Price of the Shares as to which the Option is being exercised; or

       (iv)  to the extent authorized by the Company, delivery of a properly
executed exercise notice together with such other documentation as the
Administrator and the broker, if applicable, share require to effect an exercise
of the Option and delivery to the Company of the sale or loan proceeds required
to pay the Exercise Price; or

       (v)   promissory note (in the form provided by the Company).

   f.  Restrictions on Exercise.  This Option may not be exercised if the
       ------------------------
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the
Federal Reserve Board.  As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

   g.  Termination of Relationship.  In the event an Optionee's Continuous
       ---------------------------
Status as an Employee, Consultant or Director terminates, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "Termination
Date"), exercise this Option during the Termination Period set out in the Notice
of Grant.  To the extent that Optionee was not entitled to exercise this Option
at the date of such termination, or if Optionee does not exercise this Option
within the time specified herein, the Option shall terminate.

   h.  Disability of Optionee.  Notwithstanding the provisions of Section g.
       ----------------------
above, in the event of termination of an Optionee's Continuous Status as an
Employee, Consultant or Director as a result of his or her Disability, Optionee
may, but only within twelve (12) months from the date of such termination (and
in no event later than the expiration date of the term of such Option as set
forth in the Notice of Grant) exercise the Option to the extent otherwise
entitled to exercise it at the date of such termination.  To the extent that
Optionee is not entitled to exercise the Option at the date of termination, or
if Optionee does not exercise such Option to the extent so entitled within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

   i.  Death of Optionee.  In the event of termination of Optionee's Continuous
       -----------------
Status as an Employee or Consultant as a result of the death of Optionee, the
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the date of expiration of the term of this
Option as set forth in Section k. below), by Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent the Optionee could exercise the Option at the date of death.

   j.  Non-Transferability of Option.  Options may not be sold, pledged,
       -----------------------------
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.  The terms of this Option shall
be binding upon the executors, administrators, heirs, successors and assigns of
the Optionee.

   k.  Term of Option.  This Option may be exercised only within the term set
       --------------
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.  The limitations set out
in Section 7 of the Plan regarding Options granted to more than ten percent
(10%) shareholders shall apply to this Option.

   l.  Tax Consequences.  Set forth below is a brief summary as of the date of
       ----------------
this Option of some of the federal tax consequences of exercise of this Option
and disposition of the Shares.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE
TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

      (i) Exercise of an NSO.  There may be a regular federal income tax
          ------------------
liability upon the exercise of an NSO.  The Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price.  In the case of the exercise of Option Shares which
have not vested as of the date of exercise, the Optionee will not realize
compensation income on the exercise until the date(s) on which shares vest
(i.e., have been released from the Company's repurchase option) unless the
Optionee files an election under Section 83(b) of the Code (an "83(b)
Election").  If an 83(b) election is filed, the amount of compensation income
will be determined on the date of exercise.  If Optionee is an Employee, the
Company will be required to withhold from Optionee's compensation or collect
from Optionee and pay to the applicable taxing authorities an amount equal to a
percentage of this compensation income at the time of exercise or vesting, as
applicable.

      (ii) Disposition of Shares.  If Shares are held for more than one year
           ---------------------
after the date of exercise (or the date of vesting, if later, in the case of the
exercise of unvested option shares and the Optionee had not filed an 83(b)
election at the time of such exercise, any gain realized on disposition of the
Shares will be treated as long-term capital gain for federal income tax
purposes.

                       ---------------
shall be $______ per Share for a total purchase price of $_______________.
The term "Shares" refers to the purchased Shares and all
          ------
securities received in replacement of the Shares or as stock dividends or
splits, all securities received in replacement of the Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of the Shares.

     2.  Representations of Purchaser.  Purchaser acknowledges that Purchaser
         ----------------------------
has received, read and understood the Plan and the Option Agreement and agrees
to abide by and be bound by their terms and conditions.

     3.  Rights as Stockholder.  Until the stock certificate evidencing such
         ---------------------
Shares is issued (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a stockholder shall exist with
respect to the Optioned Stock, notwithstanding the exercise of the Option.  The
Company shall issue (or cause to be issued) such stock certificate promptly
after the Option is exercised.  No adjustment will be made for a dividend or
other right for which the record date is prior to the date the stock certificate
is issued, except as provided in Section 12 of the Plan.

          Purchaser shall enjoy rights as a stockholder until such time as
Purchaser disposes of the Shares or the Company and/or its assignee(s) exercises
the Right of First Refusal hereunder.  Upon such exercise, Purchaser shall have
no further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser shall forthwith cause the certificate(s)
evidencing the Shares so purchased to be surrendered to the Company for transfer
or cancellation.

     4.  Limitations on Transfer.  In addition to any other limitation on
         -----------------------
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares while the Shares are subject
to the Company's Repurchase Option (as defined below).  After any Shares have
been released from such Repurchase Option, Purchaser shall not assign, encumber
or dispose of any interest in such Shares except in compliance with the
provisions below and applicable securities laws.

          (a)  Repurchase Option.
               -----------------

               (i) If Purchaser's Continuous Status as an Employee or Consultant
terminates for any reason (including for cause, death or disability), the
Company shall upon the date of such termination (the "Termination Date") have an
                                                      ----------------
irrevocable, exclusive option (the "Repurchase Option") for a period of 60 days
                                    -----------------
from such date to repurchase all or any portion of the Unvested Shares held by
Purchaser as of the Termination Date which have not yet been released from the
Company's Repurchase Option at the original purchase price per Share specified
in Section 1 (adjusted for any stock splits, stock dividends and the like).

               (ii) The Repurchase Option shall be exercised by the Company by
written notice to Purchaser or Purchaser's executor and, at the Company's
option, (A) by delivery to Purchaser or Purchaser's executor with such notice of
a check in the amount of the purchase price for the Shares being purchased, or
(B) in the event Purchaser is indebted to the Company, by cancellation by the
Company of an amount of such indebtedness equal to the purchase price for the
Shares being repurchased, or (C) by a combination of (A) and (B) so that the
combined payment and cancellation of indebtedness equals such purchase price.
Upon delivery of such notice and payment of the purchase price in any of the
ways described above, the Company shall become the legal and beneficial owner of
the Shares being repurchased and all rights and interest therein or related
thereto, and the Company shall have the right to transfer to its own name the
number of Shares being repurchased by the Company, without further action by
Purchaser.

               (iii)  One hundred percent (100%) of the Unvested Shares shall
initially be subject to the Repurchase Option.  The Unvested Shares shall be
released from the Repurchase Option in accordance with the Vesting Schedule set
forth in the Notice of Stock Option Grant
<PAGE>

until all Shares are released from the Repurchase Option. Fractional shares
shall be rounded to the nearest whole share.

          (b) Company's Right of First Refusal.  Before any Shares held by
              --------------------------------
Purchaser or any transferee (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section (the "Right of First Refusal").

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

               (ii)  Exercise of Right of First Refusal.  At any time within
                     ----------------------------------
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

               (iii) Purchase Price. The purchase price ("Purchase Price") for
                     --------------
the Shares purchased by the Company or its assignee(s) under this Section shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

               (iv)  Payment.  Payment of the Purchase Price shall be made, at
                     -------
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

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

               (vi) Exception for Certain Family Transfers.  Anything to the
                    --------------------------------------
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Purchaser's lifetime or on the Purchaser's death by
will or intestacy to the Purchaser's immediate family or a trust for the benefit
of the Purchaser's immediate family shall be exempt from the provisions of this
Section. "Immediate Family" as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister. In such case, the transferee
or other recipient shall receive and hold the Shares so transferred subject to
the provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

               (vii) Termination of Right of First Refusal.  The Right of First
                     -------------------------------------
Refusal shall terminate as to any Shares 90 days after the (i) first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the Securities and Exchange
Commission under the Securities Act of 1933, as amended, or (ii) a merger of the
Company with a corporation whose stock is publicly traded on a national
exchange.

     5.  Transfer of Shares; Escrow.
         --------------------------

         (a) Purchaser hereby authorizes and directs the Secretary of the
Company, or such other person designated by the Company, to transfer any
Unvested Shares as to which the Repurchase Option has been exercised from
Purchaser to the Company.

         (b) To ensure the availability for delivery of Purchaser's Unvested
Shares upon repurchase by the Company pursuant to the Repurchase Option under
Section 4(a), Purchaser hereby appoints Katrina A. Garnett of the Company, or
any other person designated by the Company, as escrow agent (the "Escrow Agent")
                                                                  ------------
and as Purchaser's attorney-in-fact to sell, assign and transfer unto the
Company such Unvested Shares, if any, as may be repurchased by the Company
pursuant to the Repurchase Option and shall, upon execution of this Agreement,
deliver and deposit with the Escrow Agent the share certificates representing
the Unvested Shares, together with two stock assignments duly endorsed in blank
and in the form attached hereto as Attachment A .  The Unvested Shares and stock
                                   ------------
assignment shall be held by the Escrow Agent in escrow pursuant to Joint Escrow
Instructions in the form attached hereto as Attachment B , until (i) the Company
                                            ------------
exercises its Repurchase Option as provided in Section 4(a), (ii) such Unvested
Shares become Vested Shares, or (iii) such time as this Agreement no longer is
in effect.  Upon vesting of the Unvested Shares, the Escrow Agent shall promptly
deliver to Purchaser the certificate or certificates representing such Shares in
the Escrow Agent's
<PAGE>

possession belonging to Purchaser, and the Escrow Agent shall be discharged of
all further obligations hereunder. Notwithstanding any of the foregoing,
however, the Escrow Agent shall nevertheless retain such certificate or
certificates as Escrow Agent if so required pursuant to other restriction
imposed pursuant to this Agreement.

          (c) The Escrow Agent shall not be liable for any act it may do or omit
to do with respect to holding the Shares in escrow and while acting in good
faith and in the exercise of its judgment.

          (d) Transfer or sale of the Shares is subject to restrictions on
transfer imposed by any applicable state and federal securities laws.  Any
transferee shall hold such Shares subject to all the provisions hereof and shall
acknowledge the same by signing a copy of this Agreement.

          (e) No Shares may be sold, pledged, hypothecated or otherwise
transferred by Purchaser until such Shares have become Vested Shares and are no
longer subject to any security agreement for the benefit of the Company.

     6.   Ownership, Voting Rights, Duties.  This Agreement shall not affect in
          --------------------------------
any way the ownership, voting rights or other rights or duties of Purchaser,
except as specifically provided herein.  Purchaser shall enjoy rights as a
stockholder until such time as Purchaser disposes of the Shares or the Company
and/or its assignee(s) exercises either the Repurchase Option or the Right of
First Refusal hereunder.  Upon any such exercise, Purchaser shall have no
further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser or the Escrow Agent, as the case may be, shall
forthwith cause the certificate(s) evidencing the Shares so purchased to be
surrendered to the Company for transfer or cancellation.

     7.   Tax Consultation.  Purchaser understands that Purchaser may suffer
          ----------------
adverse tax consequences as a result of Purchaser's purchase or disposition of
the Shares.  Purchaser represents that Purchaser has consulted with any tax
consultants Purchaser deems advisable in connection with the purchase or
disposition of the Shares and that Purchaser is not relying on the Company for
any tax advice.

     8.   Restrictive Legends; Stop-Transfer Orders; Market Standoff
          ----------------------------------------------------------

          (a) Legends.  Purchaser understands and agrees that the Company shall
              -------
cause the legends set forth below or legends substantially equivalent thereto,
to be placed upon any certificate(s) evidencing ownership of the Shares together
with any other legends that may be required by the Company or by state or
federal securities laws:

              THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
              THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
              SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
              UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY
              COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH
              OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
              THEREWITH.

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

          (b) Stop-Transfer Notices.  Purchaser agrees that, in order to ensure
              ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company  transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (c) Market Standoff.  Purchaser hereby agrees that if so requested by
              ---------------
the Company or any representative of the underwriters in connection with any
registration of the offering of any securities of the Company under the
Securities Act of 1933, as amended (the "Securities Act"), neither Purchaser nor
                                         --------------
Purchaser shall sell or otherwise transfer any Shares or other securities of the
Company during such period as the Company and the representatives of the
underwriters may request (not to exceed 180 days) following the effective date
of any registration statement of the Company filed under the Securities Act for
an underwritten public offering. The Company may impose stop-transfer
instructions with respect to Shares subject to the foregoing restrictions until
the end of such market standoff period.

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

     9.  Section 83(b) Election.  Purchaser understands that Section 83(a) of
         ----------------------
the Internal Revenue Code of 1986, as amended (the
<PAGE>

"Code"), taxes as ordinary income for a [Nonstatutory] [Incentive] Stock Option
the difference between the amount paid for the Shares and the Fair Market Value
of the Shares as of the date any restrictions on the Shares lapse. In this
context, "restriction" means the right of the Company to buy back the Shares
          -----------
pursuant to the Repurchase Option set forth in Section 4(a) of this Agreement.
Purchaser understands that Purchaser may elect to be taxed at the time the
Shares are purchased, rather than when and as the Repurchase Option expires, by
filing an election under Section 83(b) (an "83(b) Election") of the Code with
                                            --------------
the Internal Revenue Service within 30 days from the date of purchase. Even if
the Fair Market Value of the Shares at the time of the execution of this
Agreement equals the amount paid for the Shares, the election must be made to
avoid income tax treatment under Section 83(a) in the future. Purchaser
acknowledge that it is Purchaser's sole responsibility and not the Company's to
timely file the 83(b) Election, even if Purchaser requests the Company or its
representative to make this filing on Purchaser's behalf. Purchaser understands
that failure to file such an election in a timely manner may result in adverse
tax consequences for Purchaser. Purchaser further understands that an additional
copy of such election form should be filed with his or her federal income tax
return for the calendar year in which the date of this Agreement falls.
Purchaser acknowledges that the foregoing is only a summary of the effect of
United States federal income taxation with respect to purchase of the Shares
hereunder, and does not purport to be complete. Purchaser further acknowledges
that the Company has directed Purchaser to seek independent advice regarding the
applicable provisions of the Code, the income tax laws of any municipality,
state or foreign country in which Purchaser may reside, and the tax consequences
of Purchaser's death.

          Purchaser agrees that he or she will execute and deliver to the
Company with this executed Agreement a copy of the Acknowledgment and Statement
of Decision Regarding Section 83(b) Election (the "Acknowledgment") attached
                                                   --------------
hereto as Attachment C.  Purchaser further agrees that he or she will execute
          ------------
and submit with the Acknowledgment a copy of the 83(b) Election attached hereto
as Attachment D (for tax purposes in connection with the early exercise of an
   ------------
option) if Purchaser has indicated in the Acknowledgment his or her decision to
make such an election.

     10.  Notices.  All notices and other communications required or permitted
          -------
hereunder shall be in writing, shall be effective when given, and shall in any
event be deemed to be given (a) five (5) days after the deposit with the U.S.
Postal Service, if delivered by first class mail, postage prepaid (b) upon
delivery, if delivered by hand, or (c) one business day after the business day
of deposit with Federal Express or similar overnight courier, freight prepaid,
and shall be addressed (i) if to Purchaser, at Purchaser's address as set forth
beneath Purchaser's signature to this Agreement, or at such other address as
Purchaser shall have furnished to the Company in writing, (ii) if to the
Company, to CrossWorlds Software, Inc., with copy to Venture Law Group, 2775
Sand Hill Road, Menlo Park, California 94025, Attention:  Jon E. Gavenman, Esq.,
or Katrina A. Garnett, at CrossWorlds Software, Inc., or at such other address
as the Escrow Agent shall have furnished to the parties.

     11.  Successors and Assigns.  The Company may assign any of its rights
          ----------------------
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company.  Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Purchaser and his or her heirs, executors, administrators, successors and
assigns.

     12.  Interpretation.  Any dispute regarding the interpretation of this
          --------------
Agreement shall be submitted by Purchaser or by the Company forthwith to the
Company's Board of Directors or the committee thereof that administers the Plan,
which shall review such dispute at its next regular meeting.  The resolution of
such a dispute by the Board or committee shall be final and binding on the
Company and on Purchaser.

     13.  Governing Law; Severability.  This Agreement shall be governed by and
          ---------------------------
construed in accordance with the laws of the State of California excluding that
body of law pertaining to conflicts of law.  Should any provision of this
Agreement be determined by a court of law to be illegal or unenforceable, the
other provisions shall nevertheless remain effective and shall remain
enforceable.

     14.  Notices.  Any notice required or permitted hereunder shall be given in
          -------
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States mail by certified mail, with postage and fees
prepaid, addressed to the other party at its address as shown below beneath its
signature, or to such other address as such party may designate in writing from
time to time to the other party.

     15.  Further Instruments.  The parties agree to execute such further
          -------------------
instruments and to take such further action as may be reasonably necessary to
carry out the purposes and intent of this Agreement.

     16.  Delivery of Payment.  Purchaser herewith delivers to the Company the
          -------------------
full Exercise Price for the Shares.
<PAGE>

     17.  Entire Agreement.  The Plan and Notice of Grant/Option Agreement are
          ----------------
incorporated herein by reference.  This Agreement, the Plan, the Option
Agreement and the Investment Representation Statement constitute the entire
agreement of the parties with respect to the subject matter hereof and supersede
in their entirety all prior undertakings and agreements of the Company and
Purchaser with respect to the subject matter hereof, and may not be modified
adversely to the Purchaser's interest except by means of a writing signed by the
Company and Purchaser.

                      INVESTMENT REPRESENTATION STATEMENT

COMPANY:     CROSSWORLDS SOFTWARE, INC.

SECURITY:    ___________ shares of Common Stock

AMOUNT:      __________________________________

DATE:        __________________________________


     In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

     (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities.  Purchaser is
acquiring these Securities for investment for Purchaser's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

     (b) Purchaser acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.  In this connection, Purchaser
understands that, in the view of the Securities and Exchange Commission, the
statutory basis for such exemption may be unavailable if Purchaser's
representation was predicated solely upon a present intention to hold these
Securities for the minimum capital gains period specified under tax statutes,
for a deferred sale, for or until an increase or decrease in the market price of
the Securities, or for a period of one year or any other fixed period in the
future.  Purchaser further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available.  Purchaser further
acknowledges and understands that the Company is under no obligation to register
the Securities.  Purchaser understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities unless they are registered or such registration is not required in
the opinion of counsel satisfactory to the Company and any other legend required
under applicable state securities laws.

     (c) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions.  Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Option to the Purchaser, the exercise will
be exempt from registration under the Securities Act.  In the event the Company
becomes subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer
period as any market stand-off agreement may require) the Securities exempt
under Rule 701 may be resold, subject to the satisfaction of certain of the
conditions specified by Rule 144, including:  (1) the resale being made through
a broker in an unsolicited "broker's transaction" or in transactions directly
with a market maker (as said term is defined under the Securities Exchange Act
of 1934); and, in the case of an affiliate, (2) the availability of certain
public information about the Company, (3) the amount of Securities being sold
during any three month period not exceeding the limitations specified in Rule
144(e), and (4) the timely filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than one year after the later of the date the Securities were
sold by the Company or the date the Securities were sold by an affiliate of the
Company, within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than two years, the satisfaction of the conditions set forth in
sections (1), (2), (3) and (4) of the paragraph immediately above.

     (d) Purchaser hereby agrees that if so requested by the Company or any
representative of the underwriters in connection with any registration of the
offering of any securities of the Company under the Securities Act, Purchaser
shall not sell or otherwise transfer any Shares or other securities of the
Company during the 180-day period following the effective date of a registration
statement of the Company filed under the Securities Act; provided, however, that
such restriction shall only apply to the first registration statement of the
Company to become effective under the Securities Act which include securities to
be sold on behalf of the Company to the public in an underwritten public
offering under the Securities Act.  The Company may impose stop-transfer
instructions with respect to securities subject to the foregoing restrictions
until the end of such 180-day period.
<PAGE>

     (e) Purchaser further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk.  Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

                                               Signature of Purchaser:

                                               ______________________________

1. TERMS AND CONDITIONS OF GRANT

   a.  Grant of Option.  CrossWorlds Software, Inc. (the "Company"), hereby
       ----------------
grants to the Optionee (the "Optionee") named in the Notice of Grant, a
[nonstatutory ][incentive] stock option (the "Option") to purchase the total
number of shares of Common Stock (the Shares") set forth in the Notice of Grant,
at the exercise price per share set forth in the Notice of Grant (the "Exercise
Price") subject to the terms, definitions and provisions of the 1999 Stock Plan
(the "Plan") adopted by the Company, which is incorporated herein by reference.
Unless otherwise defined herein, the terms defined in the Plan shall have the
same defined meanings in this Option Agreement.

   b.  Exercise of Option.  This Option shall be exercisable during its term in
       ------------------
accordance with the Vesting Schedule set out in the Notice of Grant and with the
provisions of Section 9 of the Plan as follows:

      (i) Right to Exercise.  (a) This Option may be exercised in whole or in
          -----------------
part at any time after the Date of Grant, as to Shares which have not yet vested
under the vesting schedule indicated on the Notice of Stock Option Grant;

provided, however, that Optionee shall execute as a condition to such exercise
- --------  -------
of this Option, the Early Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit A (the "Early Exercise Agreement").  If
                             ---------       ------------------------
Optionee chooses to exercise this Option solely as to Shares which have vested
under the vesting schedule indicated on the Notice of Stock Option Grant,
Optionee shall complete and execute the form of Exercise Notice attached hereto
as Exhibit B (the "Exercise Agreement").  Notwithstanding the foregoing, the
   ---------       ------------------
Company may in its discretion prescribe or accept a different form of notice of
exercise and/or stock purchase agreement if such forms are otherwise consistent
with this Agreement, the Plan and then-applicable law.  (b) This Option may not
be exercised for a fraction of a Share. (c) In the event of Optionee's death,
Disability or other termination of the Optionee's Continuous Status as an
Employee, Consultant or Director, the exercisability of the Option is governed
by Sections g, h and i below, subject to the limitation contained in Section k.
below.  (d) In no event may this Option be exercised after the date of
expiration of the term of this Option as set forth in the Notice of Grant.

      (ii) Method of Exercise.  This Option shall be exercisable by execution
           ------------------
and delivery of the Early Exercise Agreement or the Exercise Agreement,
whichever is applicable, or of any other written notice approved for such
purpose by the Company which shall state the election to exercise the Option,
the number of Shares in respect of which the Option is being exercised, and such
other representations and agreements as to the holder's investment intent with
respect to such shares of Common Stock as may be required by the Company
pursuant to the provisions of the Plan.  Such written notice shall be signed by
the Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The written notice shall be accompanied by payment of
the Exercise Price.  This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

      No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of law and
the requirements of any stock exchange or national market system upon which the
Common Stock is then listed.  Assuming such compliance, for income tax purposes
the Shares shall be considered transferred to the Optionee on the date on which
the Option is exercised with respect to such Shares.

   c.  Optionee's Representations.  In the event the Shares purchasable pursuant
       --------------------------
to the exercise of this Option have not been registered under the Securities Act
of 1933, as amended, at the time this Option is exercised, Optionee shall, if
required by the Company, concurrently with the exercise of all or any portion of
this Option, deliver to the Company his or her Investment Representation
Statement in the form attached hereto as Exhibit C.

   d.  Lock-Up Period.  Optionee hereby agrees that if so requested by the
       --------------
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
longer period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act; provided, however, that such restriction shall apply only  to
the first registration statement of the Company to become effective under the
Securities Act that includes securities to be sold on behalf of the Company to
the public in an underwritten public offering under the Securities Act.  The
Company may impose stop-transfer instructions with respect to securities subject
to the foregoing restrictions until the end of such Market Standoff Period.

   e.  Method of Payment.  Payment of the Exercise Price shall be by any of the
       -----------------
following, or a combination thereof, at the election of the Optionee:

       (i)   cash; or

       (ii)  check; or

       (iii) surrender of other shares of Common Stock of the Company which (A)
in the case of Shares acquired pursuant to the exercise of a Company option,
have been owned by the Optionee for more than six (6) months on the date of
surrender, and (B) have a Fair Market Value on the date of surrender equal to
the Exercise Price of the Shares as to which the Option is being exercised; or

       (iv)  to the extent authorized by the Company, delivery of a properly
executed exercise notice together with such other documentation as the
Administrator and the broker, if applicable, share require to effect an exercise
of the Option and delivery to the Company of the sale or loan proceeds required
to pay the Exercise Price; or

       (v)   promissory note (in the form provided by the Company).

   f.  Restrictions on Exercise.  This Option may not be exercised if the
       ------------------------
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the
Federal Reserve Board.  As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

   g.  Termination of Relationship.  In the event an Optionee's Continuous
       ---------------------------
Status as an Employee, Consultant or Director terminates, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "Termination
Date"), exercise this Option during the Termination Period set out in the Notice
of Grant.  To the extent that Optionee was not entitled to exercise this Option
at the date of such termination, or if Optionee does not exercise this Option
within the time specified herein, the Option shall terminate.

   h.  Disability of Optionee.  Notwithstanding the provisions of Section g.
       ----------------------
above, in the event of termination of an Optionee's Continuous Status as an
Employee, Consultant or Director as a result of his or her Disability, Optionee
may, but only within twelve (12) months from the date of such termination (and
in no event later than the expiration date of the term of such Option as set
forth in the Notice of Grant) exercise the Option to the extent otherwise
entitled to exercise it at the date of such termination.  To the extent that
Optionee is not entitled to exercise the Option at the date of termination, or
if Optionee does not exercise such Option to the extent so entitled within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

   i.  Death of Optionee.  In the event of termination of Optionee's Continuous
       -----------------
Status as an Employee or Consultant as a result of the death of Optionee, the
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the date of expiration of the term of this
Option as set forth in Section k. below), by Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent the Optionee could exercise the Option at the date of death.

   j.  Non-Transferability of Option.  Options may not be sold, pledged,
       -----------------------------
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.  The terms of this Option shall
be binding upon the executors, administrators, heirs, successors and assigns of
the Optionee.

   k.  Term of Option.  This Option may be exercised only within the term set
       --------------
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.  The limitations set out
in Section 7 of the Plan regarding Options granted to more than ten percent
(10%) shareholders shall apply to this Option.

   l.  Tax Consequences.  Set forth below is a brief summary as of the date of
       ----------------
this Option of some of the federal tax consequences of exercise of this Option
and disposition of the Shares.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE
TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

      (i) Exercise of an NSO.  There may be a regular federal income tax
          ------------------
liability upon the exercise of an NSO.  The Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price.  In the case of the exercise of Option Shares which
have not vested as of the date of exercise, the Optionee will not realize
compensation income on the exercise until the date(s) on which shares vest
(i.e., have been released from the Company's repurchase option) unless the
Optionee files an election under Section 83(b) of the Code (an "83(b)
Election").  If an 83(b) election is filed, the amount of compensation income
will be determined on the date of exercise.  If Optionee is an Employee, the
Company will be required to withhold from Optionee's compensation or collect
from Optionee and pay to the applicable taxing authorities an amount equal to a
percentage of this compensation income at the time of exercise or vesting, as
applicable.

      (ii) Disposition of Shares.  If Shares are held for more than one year
           ---------------------
after the date of exercise (or the date of vesting, if later, in the case of the
exercise of unvested option shares and the Optionee had not filed an 83(b)
election at the time of such exercise, any gain realized on disposition of the
Shares will be treated as long-term capital gain for federal income tax
purposes.

or cancellation.

     4.  Limitations on Transfer.  In addition to any other limitation on
         -----------------------
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares while the Shares are subject
to the Company's Repurchase Option (as defined below).  After any Shares have
been released from such Repurchase Option, Purchaser shall not assign, encumber
or dispose of any interest in such Shares except in compliance with the
provisions below and applicable securities laws.

          (a)  Repurchase Option.
               -----------------

               (i) If Purchaser's Continuous Status as an Employee or Consultant
terminates for any reason (including for cause, death or disability), the
Company shall upon the date of such termination (the "Termination Date") have an
                                                      ----------------
irrevocable, exclusive option (the "Repurchase Option") for a period of 60 days
                                    -----------------
from such date to repurchase all or any portion of the Unvested Shares held by
Purchaser as of the Termination Date which have not yet been released from the
Company's Repurchase Option at the original purchase price per Share specified
in Section 1 (adjusted for any stock splits, stock dividends and the like).

               (ii) The Repurchase Option shall be exercised by the Company by
written notice to Purchaser or Purchaser's executor and, at the Company's
option, (A) by delivery to Purchaser or Purchaser's executor with such notice of
a check in the amount of the purchase price for the Shares being purchased, or
(B) in the event Purchaser is indebted to the Company, by cancellation by the
Company of an amount of such indebtedness equal to the purchase price for the
Shares being repurchased, or (C) by a combination of (A) and (B) so that the
combined payment and cancellation of indebtedness equals such purchase price.
Upon delivery of such notice and payment of the purchase price in any of the
ways described above, the Company shall become the legal and beneficial owner of
the Shares being repurchased and all rights and interest therein or related
thereto, and the Company shall have the right to transfer to its own name the
number of Shares being repurchased by the Company, without further action by
Purchaser.

               (iii)  One hundred percent (100%) of the Unvested Shares shall
initially be subject to the Repurchase Option.  The Unvested Shares shall be
released from the Repurchase Option in accordance with the Vesting Schedule set
forth in the Notice of Stock Option Grant
<PAGE>

until all Shares are released from the Repurchase Option. Fractional shares
shall be rounded to the nearest whole share.

          (b) Company's Right of First Refusal.  Before any Shares held by
              --------------------------------
Purchaser or any transferee (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section (the "Right of First Refusal").

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

               (ii)  Exercise of Right of First Refusal.  At any time within
                     ----------------------------------
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

               (iii) Purchase Price. The purchase price ("Purchase Price") for
                     --------------
the Shares purchased by the Company or its assignee(s) under this Section shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

               (iv)  Payment.  Payment of the Purchase Price shall be made, at
                     -------
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

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

               (vi) Exception for Certain Family Transfers.  Anything to the
                    --------------------------------------
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Purchaser's lifetime or on the Purchaser's death by
will or intestacy to the Purchaser's immediate family or a trust for the benefit
of the Purchaser's immediate family shall be exempt from the provisions of this
Section. "Immediate Family" as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister. In such case, the transferee
or other recipient shall receive and hold the Shares so transferred subject to
the provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

               (vii) Termination of Right of First Refusal.  The Right of First
                     -------------------------------------
Refusal shall terminate as to any Shares 90 days after the (i) first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the Securities and Exchange
Commission under the Securities Act of 1933, as amended, or (ii) a merger of the
Company with a corporation whose stock is publicly traded on a national
exchange.

     5.  Transfer of Shares; Escrow.
         --------------------------

         (a) Purchaser hereby authorizes and directs the Secretary of the
Company, or such other person designated by the Company, to transfer any
Unvested Shares as to which the Repurchase Option has been exercised from
Purchaser to the Company.

         (b) To ensure the availability for delivery of Purchaser's Unvested
Shares upon repurchase by the Company pursuant to the Repurchase Option under
Section 4(a), Purchaser hereby appoints Katrina A. Garnett of the Company, or
any other person designated by the Company, as escrow agent (the "Escrow Agent")
                                                                  ------------
and as Purchaser's attorney-in-fact to sell, assign and transfer unto the
Company such Unvested Shares, if any, as may be repurchased by the Company
pursuant to the Repurchase Option and shall, upon execution of this Agreement,
deliver and deposit with the Escrow Agent the share certificates representing
the Unvested Shares, together with two stock assignments duly endorsed in blank
and in the form attached hereto as Attachment A .  The Unvested Shares and stock
                                   ------------
assignment shall be held by the Escrow Agent in escrow pursuant to Joint Escrow
Instructions in the form attached hereto as Attachment B , until (i) the Company
                                            ------------
exercises its Repurchase Option as provided in Section 4(a), (ii) such Unvested
Shares become Vested Shares, or (iii) such time as this Agreement no longer is
in effect.  Upon vesting of the Unvested Shares, the Escrow Agent shall promptly
deliver to Purchaser the certificate or certificates representing such Shares in
the Escrow Agent's
<PAGE>

possession belonging to Purchaser, and the Escrow Agent shall be discharged of
all further obligations hereunder. Notwithstanding any of the foregoing,
however, the Escrow Agent shall nevertheless retain such certificate or
certificates as Escrow Agent if so required pursuant to other restriction
imposed pursuant to this Agreement.

          (c) The Escrow Agent shall not be liable for any act it may do or omit
to do with respect to holding the Shares in escrow and while acting in good
faith and in the exercise of its judgment.

          (d) Transfer or sale of the Shares is subject to restrictions on
transfer imposed by any applicable state and federal securities laws.  Any
transferee shall hold such Shares subject to all the provisions hereof and shall
acknowledge the same by signing a copy of this Agreement.

          (e) No Shares may be sold, pledged, hypothecated or otherwise
transferred by Purchaser until such Shares have become Vested Shares and are no
longer subject to any security agreement for the benefit of the Company.

     6.   Ownership, Voting Rights, Duties.  This Agreement shall not affect in
          --------------------------------
any way the ownership, voting rights or other rights or duties of Purchaser,
except as specifically provided herein.  Purchaser shall enjoy rights as a
stockholder until such time as Purchaser disposes of the Shares or the Company
and/or its assignee(s) exercises either the Repurchase Option or the Right of
First Refusal hereunder.  Upon any such exercise, Purchaser shall have no
further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser or the Escrow Agent, as the case may be, shall
forthwith cause the certificate(s) evidencing the Shares so purchased to be
surrendered to the Company for transfer or cancellation.

     7.   Tax Consultation.  Purchaser understands that Purchaser may suffer
          ----------------
adverse tax consequences as a result of Purchaser's purchase or disposition of
the Shares.  Purchaser represents that Purchaser has consulted with any tax
consultants Purchaser deems advisable in connection with the purchase or
disposition of the Shares and that Purchaser is not relying on the Company for
any tax advice.

     8.   Restrictive Legends; Stop-Transfer Orders; Market Standoff
          ----------------------------------------------------------

          (a) Legends.  Purchaser understands and agrees that the Company shall
              -------
cause the legends set forth below or legends substantially equivalent thereto,
to be placed upon any certificate(s) evidencing ownership of the Shares together
with any other legends that may be required by the Company or by state or
federal securities laws:

              THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
              THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
              SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
              UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY
              COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH
              OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
              THEREWITH.

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

          (b) Stop-Transfer Notices.  Purchaser agrees that, in order to ensure
              ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company  transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (c) Market Standoff.  Purchaser hereby agrees that if so requested by
              ---------------
the Company or any representative of the underwriters in connection with any
registration of the offering of any securities of the Company under the
Securities Act of 1933, as amended (the "Securities Act"), neither Purchaser nor
                                         --------------
Purchaser shall sell or otherwise transfer any Shares or other securities of the
Company during such period as the Company and the representatives of the
underwriters may request (not to exceed 180 days) following the effective date
of any registration statement of the Company filed under the Securities Act for
an underwritten public offering. The Company may impose stop-transfer
instructions with respect to Shares subject to the foregoing restrictions until
the end of such market standoff period.

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

     9.  Section 83(b) Election.  Purchaser understands that Section 83(a) of
         ----------------------
the Internal Revenue Code of 1986, as amended (the
<PAGE>

"Code"), taxes as ordinary income for a [Nonstatutory] [Incentive] Stock Option
the difference between the amount paid for the Shares and the Fair Market Value
of the Shares as of the date any restrictions on the Shares lapse. In this
context, "restriction" means the right of the Company to buy back the Shares
          -----------
pursuant to the Repurchase Option set forth in Section 4(a) of this Agreement.
Purchaser understands that Purchaser may elect to be taxed at the time the
Shares are purchased, rather than when and as the Repurchase Option expires, by
filing an election under Section 83(b) (an "83(b) Election") of the Code with
                                            --------------
the Internal Revenue Service within 30 days from the date of purchase. Even if
the Fair Market Value of the Shares at the time of the execution of this
Agreement equals the amount paid for the Shares, the election must be made to
avoid income tax treatment under Section 83(a) in the future. Purchaser
acknowledge that it is Purchaser's sole responsibility and not the Company's to
timely file the 83(b) Election, even if Purchaser requests the Company or its
representative to make this filing on Purchaser's behalf. Purchaser understands
that failure to file such an election in a timely manner may result in adverse
tax consequences for Purchaser. Purchaser further understands that an additional
copy of such election form should be filed with his or her federal income tax
return for the calendar year in which the date of this Agreement falls.
Purchaser acknowledges that the foregoing is only a summary of the effect of
United States federal income taxation with respect to purchase of the Shares
hereunder, and does not purport to be complete. Purchaser further acknowledges
that the Company has directed Purchaser to seek independent advice regarding the
applicable provisions of the Code, the income tax laws of any municipality,
state or foreign country in which Purchaser may reside, and the tax consequences
of Purchaser's death.

          Purchaser agrees that he or she will execute and deliver to the
Company with this executed Agreement a copy of the Acknowledgment and Statement
of Decision Regarding Section 83(b) Election (the "Acknowledgment") attached
                                                   --------------
hereto as Attachment C.  Purchaser further agrees that he or she will execute
          ------------
and submit with the Acknowledgment a copy of the 83(b) Election attached hereto
as Attachment D (for tax purposes in connection with the early exercise of an
   ------------
option) if Purchaser has indicated in the Acknowledgment his or her decision to
make such an election.

     10.  Notices.  All notices and other communications required or permitted
          -------
hereunder shall be in writing, shall be effective when given, and shall in any
event be deemed to be given (a) five (5) days after the deposit with the U.S.
Postal Service, if delivered by first class mail, postage prepaid (b) upon
delivery, if delivered by hand, or (c) one business day after the business day
of deposit with Federal Express or similar overnight courier, freight prepaid,
and shall be addressed (i) if to Purchaser, at Purchaser's address as set forth
beneath Purchaser's signature to this Agreement, or at such other address as
Purchaser shall have furnished to the Company in writing, (ii) if to the
Company, to CrossWorlds Software, Inc., with copy to Venture Law Group, 2775
Sand Hill Road, Menlo Park, California 94025, Attention:  Jon E. Gavenman, Esq.,
or Katrina A. Garnett, at CrossWorlds Software, Inc., or at such other address
as the Escrow Agent shall have furnished to the parties.

     11.  Successors and Assigns.  The Company may assign any of its rights
          ----------------------
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company.  Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Purchaser and his or her heirs, executors, administrators, successors and
assigns.

     12.  Interpretation.  Any dispute regarding the interpretation of this
          --------------
Agreement shall be submitted by Purchaser or by the Company forthwith to the
Company's Board of Directors or the committee thereof that administers the Plan,
which shall review such dispute at its next regular meeting.  The resolution of
such a dispute by the Board or committee shall be final and binding on the
Company and on Purchaser.

     13.  Governing Law; Severability.  This Agreement shall be governed by and
          ---------------------------
construed in accordance with the laws of the State of California excluding that
body of law pertaining to conflicts of law.  Should any provision of this
Agreement be determined by a court of law to be illegal or unenforceable, the
other provisions shall nevertheless remain effective and shall remain
enforceable.

     14.  Notices.  Any notice required or permitted hereunder shall be given in
          -------
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States mail by certified mail, with postage and fees
prepaid, addressed to the other party at its address as shown below beneath its
signature, or to such other address as such party may designate in writing from
time to time to the other party.

     15.  Further Instruments.  The parties agree to execute such further
          -------------------
instruments and to take such further action as may be reasonably necessary to
carry out the purposes and intent of this Agreement.

     16.  Delivery of Payment.  Purchaser herewith delivers to the Company the
          -------------------
full Exercise Price for the Shares.
<PAGE>

     17.  Entire Agreement.  The Plan and Notice of Grant/Option Agreement are
          ----------------
incorporated herein by reference.  This Agreement, the Plan, the Option
Agreement and the Investment Representation Statement constitute the entire
agreement of the parties with respect to the subject matter hereof and supersede
in their entirety all prior undertakings and agreements of the Company and
Purchaser with respect to the subject matter hereof, and may not be modified
adversely to the Purchaser's interest except by means of a writing signed by the
Company and Purchaser.

                  -------
Company ("Purchaser"), you are hereby authorized and directed to hold the

__________ __, 19__, between the Company and the undersigned, in accordance with
the following instructions:

          1.  In the event that the Company and/or any assignee of the Company
(referred to collectively for convenience herein as the ("Company") exercises
                                                          -------
the Company's repurchase option set forth in the Agreement, the Company shall
give to Purchaser and you a written notice specifying the number of shares of
stock to be purchased, the purchase price, and the time for a closing hereunder
at the principal office of the Company.  Purchaser and the Company hereby
irrevocably authorize and direct you to close the transaction contemplated by

          2.  At the closing, you are directed (a) to date the stock assignments
necessary for the transfer in question, (b) to fill in the number of shares
being transferred, and (c) to deliver same, together with the certificate

          3.  Purchaser irrevocably authorizes the Company to deposit with you
any certificates evidencing shares of stock to be held by you hereunder and any

option.

are specifically set forth herein and may rely and shall be protected in relying
or refraining from acting on any instrument reasonably believed by you to be
genuine and to have been signed or presented by the proper party or parties.

hereunder as Escrow Agent or as attorney-in-fact for Purchaser while acting in
good faith, and any act done or omitted by you pursuant to the advice of your
own attorneys shall be conclusive evidence of such good faith.

warnings given by any of the parties hereto or by any other person or
corporation, excepting only orders or process of courts of law and are hereby
expressly authorized to comply with and obey orders, judgments or decrees of any
court.  In case you obey or comply with any such order, judgment or
<PAGE>

decree, you shall not be liable to any of the parties hereto or to any other
person, firm or corporation by reason of such compliance, notwithstanding any
such order, judgment or decree being subsequently reversed, modified, annulled,
set aside, vacated or found to have been entered without jurisdiction.

          9.   You shall not be liable in any respect on account of the
identity, authorities or rights of the parties executing or delivering or
purporting to execute or deliver the Agreement or any documents or papers
deposited or called for hereunder .

Statute of Limitations with respect to these Joint Escrow Instructions or any
documents deposited with you.

experts as you may deem necessary properly to advise you in connection with your
obligations hereunder, may rely upon the advice of such counsel, and may pay
such counsel reasonable compensation therefor.

          12.  Your responsibilities as Escrow Agent hereunder shall terminate
if you shall cease to be an officer or agent of the Company or if you shall
resign by written notice to each party.  In the event of any such termination,
the Company shall appoint a successor Escrow Agent.

          13.  If you reasonably require other or further instruments in
connection with these Joint Escrow Instructions or obligations in respect
hereto, the necessary parties hereto shall join in furnishing such instruments.

             -------

combination thereof within 30 days after receipt of the Notice or in the manner

Company and/or its assignee(s) as provided in this Section, then the Holder may
sell or otherwise transfer such Shares to that Proposed Transferee at the

that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that

COMPANY:     CROSSWORLDS SOFTWARE, INC.

SECURITY:    ___________ shares of Common Stock

AMOUNT:      __________________________________

DATE:        __________________________________


     In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

     (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities.  Purchaser is
acquiring these Securities for investment for Purchaser's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

     (b) Purchaser acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.  In this connection, Purchaser
understands that, in the view of the Securities and Exchange Commission, the
statutory basis for such exemption may be unavailable if Purchaser's
representation was predicated solely upon a present intention to hold these
Securities for the minimum capital gains period specified under tax statutes,
for a deferred sale, for or until an increase or decrease in the market price of
the Securities, or for a period of one year or any other fixed period in the
future.  Purchaser further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available.  Purchaser further
acknowledges and understands that the Company is under no obligation to register
the Securities.  Purchaser understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities unless they are registered or such registration is not required in
the opinion of counsel satisfactory to the Company and any other legend required
under applicable state securities laws.

     (c) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions.  Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Option to the Purchaser, the exercise will
be exempt from registration under the Securities Act.  In the event the Company
becomes subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer
period as any market stand-off agreement may require) the Securities exempt
under Rule 701 may be resold, subject to the satisfaction of certain of the
conditions specified by Rule 144, including:  (1) the resale being made through
a broker in an unsolicited "broker's transaction" or in transactions directly
with a market maker (as said term is defined under the Securities Exchange Act
of 1934); and, in the case of an affiliate, (2) the availability of certain
public information about the Company, (3) the amount of Securities being sold
during any three month period not exceeding the limitations specified in Rule
144(e), and (4) the timely filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than one year after the later of the date the Securities were
sold by the Company or the date the Securities were sold by an affiliate of the
Company, within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than two years, the satisfaction of the conditions set forth in
sections (1), (2), (3) and (4) of the paragraph immediately above.

     (d) Purchaser hereby agrees that if so requested by the Company or any
representative of the underwriters in connection with any registration of the
offering of any securities of the Company under the Securities Act, Purchaser
shall not sell or otherwise transfer any Shares or other securities of the
Company during the 180-day period following the effective date of a registration
statement of the Company filed under the Securities Act; provided, however, that
such restriction shall only apply to the first registration statement of the
Company to become effective under the Securities Act which include securities to
be sold on behalf of the Company to the public in an underwritten public
offering under the Securities Act.  The Company may impose stop-transfer
instructions with respect to securities subject to the foregoing restrictions
until the end of such 180-day period.
<PAGE>

     (e) Purchaser further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk.  Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

                                               Signature of Purchaser:

                                               ______________________________

                             Employee Agreement

                         CROSSWORLDS SOFTWARE, INC.

information or trade secrets of any former or concurrent employer or other
person or entity and that I will not bring onto the premises of the Company any
unpublished document or proprietary information belonging to any such employer,

          (c) Third Party Information.  I recognize that the Company has

confidentiality of such information and to use it only for certain limited
purposes.  I agree to hold all such confidential or proprietary information in
the strictest confidence and not to disclose it to any person, firm or
corporation or to use it except as necessary in carrying out my work for the
Company consistent with the Company's agreement with such third party.

      3.  Inventions.
          -------------

          (a) Assignment of Inventions.  I agree that I will promptly make full
              ------------------------
written disclosure to the Company, will hold in trust for the sole right and
benefit of the Company, and hereby assign to the Company, or its designee, all
my right, title, and interest in and to any and all inventions, original works
of authorship, developments, concepts, improvements or trade secrets, whether or
not patentable or registrable under copyright or similar laws, which I may
solely or jointly conceive or develop or reduce to practice, or cause to be
conceived or developed or reduced to practice, during the period of time I am in
the employ of the Company (collectively referred to as "Inventions") and which
                                                        ----------

Information of the Company, (ii) result from or are suggested by work performed

or Washington only, which directly relate) to the business, or to the actual or
demonstrably anticipated research or development of the Company will be the sole
and exclusive property of the Company, and I will and hereby do assign all my
right, title and interest in such Inventions to the Company, except as provided
in Section 3(f).  I further acknowledge that all original works of authorship
which are made by me (solely or jointly with others) within the scope of and
during the period of my employment with the Company and which are protectible by
copyright are `works made for hire,' as that term is defined in the United
States Copyright Act.

          (b) Patent and Copyright Registrations.  I agree to assist the
              ----------------------------------
Company, or its designee, at the Company's expense, in every proper way to
secure the Company's rights in the Inventions and any copyrights, patents, mask
work rights or other intellectual property rights relating thereto in any and
all countries, including the disclosure to the Company of all pertinent
information and data with respect thereto, the execution of all applications,
specifications, oaths, assignments and all other instruments which the Company
shall deem necessary in order to apply for and obtain such rights and in order
to assign and convey to the Company, its successors,

                                     -2-
<PAGE>

assigns, and nominees the sole and exclusive rights, title and interest in and
to such Inventions, and any copyrights, patents, mask work rights or other
intellectual property rights relating thereto. I further agree that my
obligation to execute or cause to be executed, when it is in my power to do
so, any such instrument or papers shall continue after the termination of this
Agreement. If the Company is unable because of my mental or physical
incapacity or for any other reason to secure my signature to apply for or to
pursue any application for any United States or foreign patents or copyright
registrations covering Inventions or original works of authorship assigned to
the Company as above, then I hereby irrevocably designate and appoint the
Company and its duly authorized officers and agents as my agent and attorney
in fact, to act for and in my behalf and stead to execute and file any such
applications and to do all other lawfully permitted acts to further the
prosecution and issuance of letters patent or copyright registrations thereon
with the same legal force and effect as if executed by me.

          (c) Maintenance of Records.  I agree to keep and maintain adequate and
              ----------------------
current written records of all Inventions made by me (solely or jointly with
others) during the term of my employment with the Company.  The records will be
in the form of notes, sketches, drawings, and any other format that may be
specified by the Company.  The records will be available to and remain the sole
property of the Company at all times.

          (d) Inventions Assigned to the United States.  I agree to assign to
              ----------------------------------------
the United States government all my right, title, and interest in and to any and
all Inventions whenever such full title is required to be in the United States
by a contract between the Company and the United States or any of its agencies.

          (e) Inventions Retained and Licensed.  I provide below a list of all
              --------------------------------
inventions, original works of authorship, developments, improvements, and trade
secrets which were made by me prior to my employment with the Company
(collectively referred to as "Prior Inventions"), which belong to me, which
                              ----------------
relate to the Company's proposed business, products or research and development,
and which are not assigned to the Company hereunder; or, if no such list is
attached, I represent that there are no such Prior Inventions.  If in the course
of my employment with the Company, I incorporate into a Company product, process
or machine a Prior Invention owned by me or in which I have an interest, the
Company is hereby granted and shall have a nonexclusive, royalty-free,
irrevocable, perpetual, worldwide license to make, have made, modify, use and
sell such Prior Invention as part of or in connection with such product, process
or machine.

<PAGE>

          (f) Exception to Assignments.  I understand that the provisions of
              ------------------------
this Agreement requiring assignment of Inventions to the Company do not apply to
any invention that (i) I develop entirely on my own time; and (ii) I develop
without using Company equipment, supplies, facilities, or trade secret
information; and (iii) do not result from any work performed by me for the
Company; and (iv) do not relate (or, for employees in Kansas, Minnesota or
Washington only, do not directly relate) at the time of conception or reduction
                        --------
to practice to the Company's business, or to its actual or demonstrably
anticipated research or development.  Any such invention will be owned entirely
by me, even if developed by me during the time period in which I am employed by
the Company./1/  I will advise the Company promptly in writing of any inventions
that I believe meet the criteria for exclusion set forth herein and are not
otherwise disclosed pursuant to Section 3(e) above.

          (g) Return of Company Documents.  I agree that, at the time of leaving
              ---------------------------
the employ of the Company, I will deliver to the Company (and will not keep in
my possession, recreate or deliver to anyone else) any and all devices, records,
data, notes, reports, proposals, lists, correspondence, specifications, drawings
blueprints, sketches, materials, equipment, other documents or property, or
reproductions of any aforementioned items developed by me pursuant to my
employment with the Company or otherwise belonging to the Company, its
successors or assigns.  In the event of the termination of my employment, I
agree to sign and deliver the `Termination Certificate' attached hereto as
                             -------------------------
Exhibit B.
- ---------

     4.  Notification of New Employer. In the event that I leave the employ of
         ----------------------------
the Company, I hereby grant consent to notification by the Company to my new
employer or consulting client about my rights and obligations under this
Agreement.

     5.  No Solicitation of Employees.  In consideration for my employment by
         ----------------------------
the Company and other valuable consideration, receipt of which is hereby
acknowledged, I agree that during the period of my association with the
Company as an employee, officer and/or director and a period of twelve (12)
months thereafter, I shall not solicit the employment of any person

- -----------------
/1/ For employees in California only, the Company acknowledges the applicability
of Section 2870 of the California Labor Code, which provides:  "Any provision in
an employment agreement which provides that an employee shall assign, or offer
to assign, any of his or her rights in an invention to his or her employer shall
not apply to an invention that the employee developed entirely on his or her own
time without using the employer's equipment, supplies,  facilities, or trade
secret information except for those inventions that either:  (i) relate at the
time of conception or reduction to practice of the invention to the employer's
business, or actual or demonstrably anticipated research or development of the
employer and (ii) result from any work performed by the employee for the
employer.  To the extent a provision in an employment agreement purports to
require an employee to assign an invention otherwise excluded from being
required to be assigned under subdivision (a), the provision is against the
public policy of this state and is unenforceable."

                                     -4-
<PAGE>

who shall then be employed by the Company (as an employee or consultant) or
who shall have been employed by the Company (as an employee or consultant)
within the prior twelve (12) month period, on behalf of myself or any other
person, firm, corporation, association or other entity, directly or
indirectly.

      6.  Representations. I represent that my performance of all the terms of
          ---------------
this Agreement will not breach any agreement to keep in confidence propriety
information acquired by me in confidence or in trust prior to my employment by
the Company. I have not entered into, and I agree I will not enter into, any
oral or written agreement in conflict herewith. I agree to execute any proper
oath or verify any proper document required to carry out the terms of this
Agreement.

      7.  Arbitration and Equitable Relief.
          --------------------------------

          (a) Arbitration.  Except as provided in Section 7(b) below, I agree
              -----------
that any dispute or controversy arising out of or relating to any
interpretation, construction, performance or breach of this Agreement, shall be
settled by arbitration to be held in San Mateo County, California, in accordance
with the rules then in effect of the American Arbitration Association.  The
arbitrator may grant injunctions or other relief in such dispute or controversy.
The decision of the arbitrator shall be final, conclusive and binding on the
parties to the arbitration.  Judgment may be entered on the arbitrator's
decision in any court having jurisdiction.  The Company and I shall each pay
one-half of the costs and expenses of such arbitration, and each of us shall
separately pay our counsel fees and expenses.

          (b) Equitable Remedies.  I agree that it would be impossible or
              ------------------
inadequate to measure and calculate the Company's damages from any breach of the
covenants set forth in Sections 2, 3 and 5 herein.  Accordingly, I agree that if
I breach any such Section, the Company will have available, in addition to any
other right or remedy available, the right to obtain an injunction from a court
of competent jurisdiction restraining such breach or threatened breach and to
specific performance of any such provision of this Agreement.  I further agree
that no bond or other security shall be required in obtaining such equitable
relief and I hereby consent to the issuance of such injunction and to the
ordering of specific performance.

      8.  General Provisions.
          ------------------

          (a) Governing Law; Consent to Personal Jurisdiction.  This Agreement
              -----------------------------------------------
will be governed by the laws of the State of California as they apply to
contracts entered into and wholly to be performed within such State.  I hereby
expressly consent to the nonexclusive personal jurisdiction and venue of the
state and federal courts located in the federal Northern District of California
for any lawsuit filed there against me by the Company arising from or relating
to this Agreement.

          (b) Entire Agreement.  This Agreement sets forth the entire agreement
              ----------------
and understanding between the Company and me relating to the subject matter
herein and merges all prior discussions between us.  No modification of or
amendment to this Agreement, nor any

                                     -5-
<PAGE>

waiver of any rights under this Agreement, will be effective unless in writing
signed by the party to be charged. Any subsequent change or changes in my
duties, salary or compensation will not affect the validity or scope of this
Agreement.

          (b) Severability.  If one or more of the provisions in this Agreement
              ------------
are deemed void by law, then the remaining provisions will continue in full
force and effect.

                                     -6-
<PAGE>

          (c) Successors and Assigns.  This Agreement will be binding upon my

heirs, executors, administrators and other legal representatives and will be for
the benefit of the Company, its successors, and its assigns.

                         CROSSWORLDS SOFTWARE, INC.

                       Conflict of Interest Guidelines

     It is the policy of CrossWorlds Software, Inc. and its subsidiaries and
affiliates (together, the "Company") to conduct its affairs in strict compliance
                           -------
with the letter and spirit of the law and to adhere to the highest principles of
business ethics.  Accordingly, all officers, employees and independent
contractors must avoid activities which are in conflict, or give the appearance
of being in conflict, with these principles and with the interests of the
Company.  The following are potentially compromising situations which must be
avoided.  Any exceptions must be reported to the President and written approval
for continuation must be obtained.

     1.  Revealing confidential information to outsiders or misusing
confidential information.  Unauthorized divulging of information is a violation
of this policy whether or not for personal gain and whether or not harm to the
Company is intended.  (The Employment, Confidential Information and Invention
Assignment Agreement elaborates on this principle and is a binding agreement.)

     2.  Accepting or offering substantial gifts, excessive entertainment,
favors or payments which may be deemed to constitute undue influence or
otherwise be improper or embarrassing to the Company.

     3.  Participating in civic or professional organizations that might involve
divulging confidential information of the Company.

     4.  Initiating or approving any form of personal or social harassment of
employees.

     5.  Investing or holding outside directorship in suppliers, customers, or
competing companies, including financial speculations, where such investment or
directorship might influence in any manner a decision or course of action of the
Company.

     6.  Borrowing from or lending to employees, customers or suppliers.

     7.  Acquiring real estate of interest to the Company.

     8.  Improperly using or disclosing to the Company any proprietary
information or trade secrets of any former or concurrent employer or other
person or entity with whom obligations of confidentiality exist.

     9.  Unlawfully discussing prices, costs, customers, sales or markets with
competing companies or their employees.

     10.  Making any unlawful agreement with distributors with respect to
prices.
<PAGE>

     11.  Improperly using or authorizing the use of any inventions which are
the subject of patent claims of any other person or entity.

     12.  Engaging in any conduct which is not in the best interest of the
Company.

     Each officer, employee and independent contractor must take every necessary
action to ensure compliance with these guidelines and to bring problem areas to
the attention of higher management for review.  Violations of this conflict of
interest policy may result in discharge without warning.

equipment, other documents or property, or reproductions of any aforementioned

original works of authorship (as defined therein) conceived or made by me
(solely or jointly with others) covered by the Employee Agreement.

     I further agree that, in compliance with the Employment Agreement, I will
preserve as confidential all trade secrets, confidential knowledge, data or
other proprietary information relating to products, processes, know-how,
designs, formulas, developmental or experimental work, computer programs, data
bases, other original works of authorship, customer lists, business plans,
financial information or other subject matter pertaining to any business of the
Company or any of its employees, clients, consultants or licensees.

     I further agree that for twelve (12) months from this date, I shall not
solicit the employment of any person who shall then be employed by the Company
(as an employee or consultant) or who shall have been employed by the Company

warrants to the Company that he is under no obligations or commitments, whether

Agreement. The Executive represents and warrants that he will not use or
disclose, in connection with his employment by the Company, any trade secrets or
other proprietary information or intellectual property in which the Executive or

Company as contemplated by this Agreement will not infringe or violate the
rights of any other person or entity. The Executive represents and warrants to
the Company that he has returned all property and confidential information
belonging to any prior employers.

               (d)  Commencement Date.  The Executive shall commence full-time
                    -----------------
Employment on January 1, 2000.

               (e)  Office Location.  The Executive's office will be located in
                    ---------------
Westport, Connecticut.

          2.  Cash and Incentive Compensation.
              -------------------------------

               (a)  Salary.  The Company shall pay the Executive as compensation
                    ------
for his services a base salary at the rate of not less than $20,833.33 per
month, payable in accordance with the Company's standard payroll schedule. (The
compensation specified in this Subsection (a), together with any increases in
such compensation that the Company may grant from time to time, is referred to
in this Agreement as "Base Salary.")

               (b)  Sign-On Bonus.  The Executive shall be paid a sign-on bonus
                    -------------
of $300,000, less all applicable deductions, that will be earned when Executive

               (c)  Target Bonus.  The Executive will be eligible to earn an
                    ------------

<PAGE>

established by the Company's Chief Executive Officer. Any bonus payable
hereunder shall be payable annually in accordance with the Company's normal
practices and policies.

               (d)  Stock Options.
                    -------------

                  (i)  Option Grant.  Subject to the approval of the Company's
                       ------------
Board of Directors, the Company shall grant the Executive a stock option to
purchase 400,000 shares of the Company's common stock. This option will be
granted as soon as reasonably practicable after the date Executive's Employment
commences. The per share exercise price of the option will be equal to the per
share fair market value of the common stock on the date of grant, as determined
by the Board of Directors. The term of such option shall be 10 years, subject to
earlier expiration in the event of the termination of the Executive's
Employment. Such option shall be immediately exercisable, if Executive elects to
do so, but the purchased shares shall be subject to repurchase by the Company at
the exercise price in the event that the Executive's Employment terminates
before he vests in the shares, except that 50,000 shares of the option shall
vest immediately upon commencement of employment and will not be subject to the
Company's right of repurchase. As to the remaining 350,000 shares of the option,
the Executive shall vest in the option shares, and the Company's repurchase
right if applicable shall lapse, in equal monthly installments over forty-eight
(48) months from the date Executive's Employment commences.

                  (ii) Exercise of Options.  The option grant made pursuant to
                       -------------------
subsection (i) above shall be subject to the Company's standard form of stock
option agreement, a copy of which is attached hereto as an exhibit and must be
executed as a condition of the grant and exercise. Executive shall have the
right to exercise his option shares while he remains employed by the Company by
delivering a full recourse promissory note secured by a pledge of the shares
purchased thereunder. If required under the laws of the Company's state of
incorporation, Executive shall pay cash for the par value of the exercised
option shares. Interest on the promissory note shall accrue at the minimum
applicable federal rate under the Internal Revenue Code to avoid imputed income.
The principal balance and interest shall be due in full on the earlier of the
fourth anniversary of Executive's hire date or 90 days after the termination of
Executive's Employment. The note shall be subject to such other terms and
conditions as may be agreed to by the Company and Executive. The credit extended
to Executive hereunder shall equal the aggregate option price payable for the
purchased shares.

                  (iii)  Registration of Shares.  The Company will take all
                         ----------------------
reasonable steps at its sole cost and expense to register Executive's stock
following an initial public offering so that Executive can sell any vested
shares of stock if he so chooses following the expiration of any applicable
lock-up period. Nothing herein will be interpreted as requiring the Company to
breach any rights regarding the registration of securities under the Securities
Act of 1933.

                  (iv)   Effect of Termination of Employment.  If the Company
                         -----------------------------------
terminates Executive's Employment "Without Cause," or Executive resigns for
"Good Reason," then Executive shall receive additional vesting of all of his
outstanding options and, if applicable, the Company's repurchase rights as to
such shares will lapse, as if he had provided an additional twelve (12) months
of service from the date employment terminates.

<PAGE>

                  (v)  Effect of Change of Control.  In the event of a Change of
                       ---------------------------
Control during the period of Executive's employment, then each of Executive's
outstanding options will become fully vested and, if applicable, the Company's
repurchase rights will lapse as to all shares subject to all options.

                  (vi)  Definitions.
                        -----------

                        (a)  "Change of Control."  For all purposes under this
                             --------------------
Agreement, "Change of Control" shall mean (i) a merger or consolidation in which
securities possessing at least fifty percent (50%) of the total combined voting
power of the Corporation's outstanding securities are transferred to a person or
persons different from the persons holding those securities immediately prior to
such transaction, or (ii) the sale, transfer or other disposition of all or
substantially all of the Corporation's assets in complete liquidation or
dissolution of the Corporation.

                        (b)  "Good Reason."  For all purposes under this
                             --------------
Agreement, "Good Reason" for Executive's resignation will exist if he resigns
within sixty days of any of the following: (i) any reduction in his base salary
or target bonus; (ii) any material reduction in his benefits; (iii) a change in
his position with the Company or a successor company which materially reduces
his duties or level of responsibility; or (iv) any requirement that he relocate
his place of employment by more than thirty-five (35) miles from his then
current office, provided such reduction, change or reduction is effected by the
Company without his written consent. A resignation by Executive under any other
circumstances or for any other reasons will be a resignation "Without Good
Reason."

                        (c)  Termination for "Cause."  For all purposes under
                             ------------------------
this Agreement, a termination for "Cause" shall mean a good faith determination
by the Company's Board of Directors that Executive's Employment be terminated
for any of the following reasons: (i) willful misconduct which materially
damages the Company; (ii) misappropriation of the assets of the Company; or
(iii) conviction of, or a plea of "guilty" or "no contest" to, a felony under
the laws of the United States or any state thereof. A termination of Executive's
Employment in any other circumstances or for any other reasons will be a
termination "Without Cause."

          3.  Vacation and Executive Benefits.  During the term of his
              -------------------------------
Employment, the Executive shall be eligible for paid vacation in accordance with
the Company's standard policy for similarly situated employees, as it may be
amended from time to time. During the term of his Employment, the Executive
shall be eligible to participate in any employee benefit plans maintained by the
Company for similarly situated employees, subject in each case to the generally
applicable terms and conditions of the plan in question and to the
determinations of any person or committee administering such plan.

          4.  Business Expenses.  During the term of his Employment, the
              -----------------
Executive shall be authorized to incur necessary and reasonable travel,
entertainment and other business expenses in connection with his duties
hereunder. The Company shall reimburse the Executive for such expenses upon
presentation of an itemized account and appropriate supporting documentation,
all in accordance with the Company's generally applicable policies.

1. TERMS AND CONDITIONS OF GRANT

   a.  Grant of Option.  CrossWorlds Software, Inc. (the "Company"), hereby
       ----------------
grants to the Optionee (the "Optionee") named in the Notice of Grant, a
[nonstatutory ][incentive] stock option (the "Option") to purchase the total
number of shares of Common Stock (the Shares") set forth in the Notice of Grant,
at the exercise price per share set forth in the Notice of Grant (the "Exercise
Price") subject to the terms, definitions and provisions of the 1999 Stock Plan
(the "Plan") adopted by the Company, which is incorporated herein by reference.
Unless otherwise defined herein, the terms defined in the Plan shall have the
same defined meanings in this Option Agreement.

   b.  Exercise of Option.  This Option shall be exercisable during its term in
       ------------------
accordance with the Vesting Schedule set out in the Notice of Grant and with the
provisions of Section 9 of the Plan as follows:

      (i) Right to Exercise.  (a) This Option may be exercised in whole or in
          -----------------
part at any time after the Date of Grant, as to Shares which have not yet vested
under the vesting schedule indicated on the Notice of Stock Option Grant;

provided, however, that Optionee shall execute as a condition to such exercise
- --------  -------
of this Option, the Early Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit A (the "Early Exercise Agreement").  If
                             ---------       ------------------------
Optionee chooses to exercise this Option solely as to Shares which have vested
under the vesting schedule indicated on the Notice of Stock Option Grant,
Optionee shall complete and execute the form of Exercise Notice attached hereto
as Exhibit B (the "Exercise Agreement").  Notwithstanding the foregoing, the
   ---------       ------------------
Company may in its discretion prescribe or accept a different form of notice of
exercise and/or stock purchase agreement if such forms are otherwise consistent
with this Agreement, the Plan and then-applicable law.  (b) This Option may not
be exercised for a fraction of a Share. (c) In the event of Optionee's death,
Disability or other termination of the Optionee's Continuous Status as an
Employee, Consultant or Director, the exercisability of the Option is governed
by Sections g, h and i below, subject to the limitation contained in Section k.
below.  (d) In no event may this Option be exercised after the date of
expiration of the term of this Option as set forth in the Notice of Grant.

      (ii) Method of Exercise.  This Option shall be exercisable by execution
           ------------------
and delivery of the Early Exercise Agreement or the Exercise Agreement,
whichever is applicable, or of any other written notice approved for such
purpose by the Company which shall state the election to exercise the Option,
the number of Shares in respect of which the Option is being exercised, and such
other representations and agreements as to the holder's investment intent with
respect to such shares of Common Stock as may be required by the Company
pursuant to the provisions of the Plan.  Such written notice shall be signed by
the Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The written notice shall be accompanied by payment of
the Exercise Price.  This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

      No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of law and
the requirements of any stock exchange or national market system upon which the
Common Stock is then listed.  Assuming such compliance, for income tax purposes
the Shares shall be considered transferred to the Optionee on the date on which
the Option is exercised with respect to such Shares.

   c.  Optionee's Representations.  In the event the Shares purchasable pursuant
       --------------------------
to the exercise of this Option have not been registered under the Securities Act
of 1933, as amended, at the time this Option is exercised, Optionee shall, if
required by the Company, concurrently with the exercise of all or any portion of
this Option, deliver to the Company his or her Investment Representation
Statement in the form attached hereto as Exhibit C.

   d.  Lock-Up Period.  Optionee hereby agrees that if so requested by the
       --------------
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
longer period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act; provided, however, that such restriction shall apply only  to
the first registration statement of the Company to become effective under the
Securities Act that includes securities to be sold on behalf of the Company to
the public in an underwritten public offering under the Securities Act.  The
Company may impose stop-transfer instructions with respect to securities subject
to the foregoing restrictions until the end of such Market Standoff Period.

   e.  Method of Payment.  Payment of the Exercise Price shall be by any of the
       -----------------
following, or a combination thereof, at the election of the Optionee:

       (i)   cash; or

       (ii)  check; or

       (iii) surrender of other shares of Common Stock of the Company which (A)
in the case of Shares acquired pursuant to the exercise of a Company option,
have been owned by the Optionee for more than six (6) months on the date of
surrender, and (B) have a Fair Market Value on the date of surrender equal to
the Exercise Price of the Shares as to which the Option is being exercised; or

       (iv)  to the extent authorized by the Company, delivery of a properly
executed exercise notice together with such other documentation as the
Administrator and the broker, if applicable, share require to effect an exercise
of the Option and delivery to the Company of the sale or loan proceeds required
to pay the Exercise Price; or

       (v)   promissory note (in the form provided by the Company).

   f.  Restrictions on Exercise.  This Option may not be exercised if the
       ------------------------
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the
Federal Reserve Board.  As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

   g.  Termination of Relationship.  In the event an Optionee's Continuous
       ---------------------------
Status as an Employee, Consultant or Director terminates, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "Termination
Date"), exercise this Option during the Termination Period set out in the Notice
of Grant.  To the extent that Optionee was not entitled to exercise this Option
at the date of such termination, or if Optionee does not exercise this Option
within the time specified herein, the Option shall terminate.

   h.  Disability of Optionee.  Notwithstanding the provisions of Section g.
       ----------------------
above, in the event of termination of an Optionee's Continuous Status as an
Employee, Consultant or Director as a result of his or her Disability, Optionee
may, but only within twelve (12) months from the date of such termination (and
in no event later than the expiration date of the term of such Option as set
forth in the Notice of Grant) exercise the Option to the extent otherwise
entitled to exercise it at the date of such termination.  To the extent that
Optionee is not entitled to exercise the Option at the date of termination, or
if Optionee does not exercise such Option to the extent so entitled within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

   i.  Death of Optionee.  In the event of termination of Optionee's Continuous
       -----------------
Status as an Employee or Consultant as a result of the death of Optionee, the
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the date of expiration of the term of this
Option as set forth in Section k. below), by Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent the Optionee could exercise the Option at the date of death.

   j.  Non-Transferability of Option.  Options may not be sold, pledged,
       -----------------------------
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.  The terms of this Option shall
be binding upon the executors, administrators, heirs, successors and assigns of
the Optionee.

   k.  Term of Option.  This Option may be exercised only within the term set
       --------------
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.  The limitations set out
in Section 7 of the Plan regarding Options granted to more than ten percent
(10%) shareholders shall apply to this Option.

   l.  Tax Consequences.  Set forth below is a brief summary as of the date of
       ----------------
this Option of some of the federal tax consequences of exercise of this Option
and disposition of the Shares.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE
TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

      (i) Exercise of an NSO.  There may be a regular federal income tax
          ------------------
liability upon the exercise of an NSO.  The Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price.  In the case of the exercise of Option Shares which
have not vested as of the date of exercise, the Optionee will not realize
compensation income on the exercise until the date(s) on which shares vest
(i.e., have been released from the Company's repurchase option) unless the
Optionee files an election under Section 83(b) of the Code (an "83(b)
Election").  If an 83(b) election is filed, the amount of compensation income
will be determined on the date of exercise.  If Optionee is an Employee, the
Company will be required to withhold from Optionee's compensation or collect
from Optionee and pay to the applicable taxing authorities an amount equal to a
percentage of this compensation income at the time of exercise or vesting, as
applicable.

      (ii) Disposition of Shares.  If Shares are held for more than one year
           ---------------------
after the date of exercise (or the date of vesting, if later, in the case of the
exercise of unvested option shares and the Optionee had not filed an 83(b)
election at the time of such exercise, any gain realized on disposition of the
Shares will be treated as long-term capital gain for federal income tax
purposes.

"Vested Shares") and _____________ Shares which have not yet vested under such
- --------------
Vesting Schedule (the "Unvested Shares").  The purchase price for the Shares
                       ---------------

     2.  Representations of Purchaser.  Purchaser acknowledges that Purchaser
         ----------------------------
has received, read and understood the Plan and the Option Agreement and agrees
to abide by and be bound by their terms and conditions.

     3.  Rights as Stockholder.  Until the stock certificate evidencing such

Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a stockholder shall exist with
respect to the Optioned Stock, notwithstanding the exercise of the Option.  The
Company shall issue (or cause to be issued) such stock certificate promptly
after the Option is exercised.  No adjustment will be made for a dividend or
other right for which the record date is prior to the date the stock certificate
is issued, except as provided in Section 12 of the Plan.

          Purchaser shall enjoy rights as a stockholder until such time as

the Right of First Refusal hereunder.  Upon such exercise, Purchaser shall have
no further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser shall forthwith cause the certificate(s)
evidencing the Shares so purchased to be surrendered to the Company for transfer
or cancellation.

     4.  Limitations on Transfer.  In addition to any other limitation on
         -----------------------
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares while the Shares are subject
to the Company's Repurchase Option (as defined below).  After any Shares have
been released from such Repurchase Option, Purchaser shall not assign, encumber
or dispose of any interest in such Shares except in compliance with the
provisions below and applicable securities laws.

          (a)  Repurchase Option.
               -----------------

               (i) If Purchaser's Continuous Status as an Employee or Consultant
terminates for any reason (including for cause, death or disability), the
Company shall upon the date of such termination (the "Termination Date") have an
                                                      ----------------
irrevocable, exclusive option (the "Repurchase Option") for a period of 60 days
                                    -----------------
from such date to repurchase all or any portion of the Unvested Shares held by
Purchaser as of the Termination Date which have not yet been released from the
Company's Repurchase Option at the original purchase price per Share specified
in Section 1 (adjusted for any stock splits, stock dividends and the like).

               (ii) The Repurchase Option shall be exercised by the Company by
written notice to Purchaser or Purchaser's executor and, at the Company's
option, (A) by delivery to Purchaser or Purchaser's executor with such notice of
a check in the amount of the purchase price for the Shares being purchased, or
(B) in the event Purchaser is indebted to the Company, by cancellation by the
Company of an amount of such indebtedness equal to the purchase price for the
Shares being repurchased, or (C) by a combination of (A) and (B) so that the
combined payment and cancellation of indebtedness equals such purchase price.
Upon delivery of such notice and payment of the purchase price in any of the
ways described above, the Company shall become the legal and beneficial owner of
the Shares being repurchased and all rights and interest therein or related
thereto, and the Company shall have the right to transfer to its own name the
number of Shares being repurchased by the Company, without further action by
Purchaser.

               (iii)  One hundred percent (100%) of the Unvested Shares shall
initially be subject to the Repurchase Option.  The Unvested Shares shall be
released from the Repurchase Option in accordance with the Vesting Schedule set
forth in the Notice of Stock Option Grant
<PAGE>

until all Shares are released from the Repurchase Option. Fractional shares
shall be rounded to the nearest whole share.

          (b) Company's Right of First Refusal.  Before any Shares held by
              --------------------------------
Purchaser or any transferee (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section (the "Right of First Refusal").

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

               (ii)  Exercise of Right of First Refusal.  At any time within
                     ----------------------------------
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

               (iii) Purchase Price. The purchase price ("Purchase Price") for
                     --------------
the Shares purchased by the Company or its assignee(s) under this Section shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

               (iv)  Payment.  Payment of the Purchase Price shall be made, at
                     -------
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

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

               (vi) Exception for Certain Family Transfers.  Anything to the
                    --------------------------------------
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Purchaser's lifetime or on the Purchaser's death by
will or intestacy to the Purchaser's immediate family or a trust for the benefit
of the Purchaser's immediate family shall be exempt from the provisions of this
Section. "Immediate Family" as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister. In such case, the transferee
or other recipient shall receive and hold the Shares so transferred subject to
the provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

               (vii) Termination of Right of First Refusal.  The Right of First
                     -------------------------------------
Refusal shall terminate as to any Shares 90 days after the (i) first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the Securities and Exchange
Commission under the Securities Act of 1933, as amended, or (ii) a merger of the
Company with a corporation whose stock is publicly traded on a national
exchange.

     5.  Transfer of Shares; Escrow.
         --------------------------

         (a) Purchaser hereby authorizes and directs the Secretary of the
Company, or such other person designated by the Company, to transfer any
Unvested Shares as to which the Repurchase Option has been exercised from
Purchaser to the Company.

         (b) To ensure the availability for delivery of Purchaser's Unvested
Shares upon repurchase by the Company pursuant to the Repurchase Option under
Section 4(a), Purchaser hereby appoints Katrina A. Garnett of the Company, or
any other person designated by the Company, as escrow agent (the "Escrow Agent")
                                                                  ------------
and as Purchaser's attorney-in-fact to sell, assign and transfer unto the
Company such Unvested Shares, if any, as may be repurchased by the Company
pursuant to the Repurchase Option and shall, upon execution of this Agreement,
deliver and deposit with the Escrow Agent the share certificates representing
the Unvested Shares, together with two stock assignments duly endorsed in blank
and in the form attached hereto as Attachment A .  The Unvested Shares and stock
                                   ------------
assignment shall be held by the Escrow Agent in escrow pursuant to Joint Escrow
Instructions in the form attached hereto as Attachment B , until (i) the Company
                                            ------------
exercises its Repurchase Option as provided in Section 4(a), (ii) such Unvested
Shares become Vested Shares, or (iii) such time as this Agreement no longer is
in effect.  Upon vesting of the Unvested Shares, the Escrow Agent shall promptly
deliver to Purchaser the certificate or certificates representing such Shares in
the Escrow Agent's
<PAGE>

possession belonging to Purchaser, and the Escrow Agent shall be discharged of
all further obligations hereunder. Notwithstanding any of the foregoing,
however, the Escrow Agent shall nevertheless retain such certificate or
certificates as Escrow Agent if so required pursuant to other restriction
imposed pursuant to this Agreement.

          (c) The Escrow Agent shall not be liable for any act it may do or omit
to do with respect to holding the Shares in escrow and while acting in good
faith and in the exercise of its judgment.

          (d) Transfer or sale of the Shares is subject to restrictions on
transfer imposed by any applicable state and federal securities laws.  Any
transferee shall hold such Shares subject to all the provisions hereof and shall
acknowledge the same by signing a copy of this Agreement.

          (e) No Shares may be sold, pledged, hypothecated or otherwise
transferred by Purchaser until such Shares have become Vested Shares and are no
longer subject to any security agreement for the benefit of the Company.

     6.   Ownership, Voting Rights, Duties.  This Agreement shall not affect in
          --------------------------------
any way the ownership, voting rights or other rights or duties of Purchaser,
except as specifically provided herein.  Purchaser shall enjoy rights as a
stockholder until such time as Purchaser disposes of the Shares or the Company
and/or its assignee(s) exercises either the Repurchase Option or the Right of
First Refusal hereunder.  Upon any such exercise, Purchaser shall have no
further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser or the Escrow Agent, as the case may be, shall
forthwith cause the certificate(s) evidencing the Shares so purchased to be
surrendered to the Company for transfer or cancellation.

     7.   Tax Consultation.  Purchaser understands that Purchaser may suffer
          ----------------
adverse tax consequences as a result of Purchaser's purchase or disposition of
the Shares.  Purchaser represents that Purchaser has consulted with any tax
consultants Purchaser deems advisable in connection with the purchase or
disposition of the Shares and that Purchaser is not relying on the Company for
any tax advice.

     8.   Restrictive Legends; Stop-Transfer Orders; Market Standoff
          ----------------------------------------------------------

          (a) Legends.  Purchaser understands and agrees that the Company shall
              -------
cause the legends set forth below or legends substantially equivalent thereto,
to be placed upon any certificate(s) evidencing ownership of the Shares together
with any other legends that may be required by the Company or by state or
federal securities laws:

              THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
              THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
              SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
              UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY
              COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH
              OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
              THEREWITH.

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

          (b) Stop-Transfer Notices.  Purchaser agrees that, in order to ensure
              ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company  transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (c) Market Standoff.  Purchaser hereby agrees that if so requested by
              ---------------
the Company or any representative of the underwriters in connection with any
registration of the offering of any securities of the Company under the
Securities Act of 1933, as amended (the "Securities Act"), neither Purchaser nor
                                         --------------
Purchaser shall sell or otherwise transfer any Shares or other securities of the
Company during such period as the Company and the representatives of the
underwriters may request (not to exceed 180 days) following the effective date
of any registration statement of the Company filed under the Securities Act for
an underwritten public offering. The Company may impose stop-transfer
instructions with respect to Shares subject to the foregoing restrictions until
the end of such market standoff period.

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

     9.  Section 83(b) Election.  Purchaser understands that Section 83(a) of
         ----------------------
the Internal Revenue Code of 1986, as amended (the
<PAGE>

"Code"), taxes as ordinary income for a [Nonstatutory] [Incentive] Stock Option
the difference between the amount paid for the Shares and the Fair Market Value
of the Shares as of the date any restrictions on the Shares lapse. In this
context, "restriction" means the right of the Company to buy back the Shares
          -----------
pursuant to the Repurchase Option set forth in Section 4(a) of this Agreement.
Purchaser understands that Purchaser may elect to be taxed at the time the
Shares are purchased, rather than when and as the Repurchase Option expires, by
filing an election under Section 83(b) (an "83(b) Election") of the Code with
                                            --------------
the Internal Revenue Service within 30 days from the date of purchase. Even if
the Fair Market Value of the Shares at the time of the execution of this
Agreement equals the amount paid for the Shares, the election must be made to
avoid income tax treatment under Section 83(a) in the future. Purchaser
acknowledge that it is Purchaser's sole responsibility and not the Company's to
timely file the 83(b) Election, even if Purchaser requests the Company or its
representative to make this filing on Purchaser's behalf. Purchaser understands
that failure to file such an election in a timely manner may result in adverse
tax consequences for Purchaser. Purchaser further understands that an additional
copy of such election form should be filed with his or her federal income tax
return for the calendar year in which the date of this Agreement falls.
Purchaser acknowledges that the foregoing is only a summary of the effect of
United States federal income taxation with respect to purchase of the Shares
hereunder, and does not purport to be complete. Purchaser further acknowledges
that the Company has directed Purchaser to seek independent advice regarding the
applicable provisions of the Code, the income tax laws of any municipality,
state or foreign country in which Purchaser may reside, and the tax consequences
of Purchaser's death.

          Purchaser agrees that he or she will execute and deliver to the
Company with this executed Agreement a copy of the Acknowledgment and Statement
of Decision Regarding Section 83(b) Election (the "Acknowledgment") attached
                                                   --------------
hereto as Attachment C.  Purchaser further agrees that he or she will execute
          ------------
and submit with the Acknowledgment a copy of the 83(b) Election attached hereto
as Attachment D (for tax purposes in connection with the early exercise of an
   ------------
option) if Purchaser has indicated in the Acknowledgment his or her decision to
make such an election.

     10.  Notices.  All notices and other communications required or permitted
          -------
hereunder shall be in writing, shall be effective when given, and shall in any
event be deemed to be given (a) five (5) days after the deposit with the U.S.

          ----------------------
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company.  Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Purchaser and his or her heirs, executors, administrators, successors and
assigns.

     12.  Interpretation.  Any dispute regarding the interpretation of this
          --------------
Agreement shall be submitted by Purchaser or by the Company forthwith to the
Company's Board of Directors or the committee thereof that administers the Plan,
which shall review such dispute at its next regular meeting.  The resolution of
such a dispute by the Board or committee shall be final and binding on the
Company and on Purchaser.

     13.  Governing Law; Severability.  This Agreement shall be governed by and
          ---------------------------
construed in accordance with the laws of the State of California excluding that
body of law pertaining to conflicts of law.  Should any provision of this
Agreement be determined by a court of law to be illegal or unenforceable, the
other provisions shall nevertheless remain effective and shall remain
enforceable.

     14.  Notices.  Any notice required or permitted hereunder shall be given in
          -------

in their entirety all prior undertakings and agreements of the Company and
Purchaser with respect to the subject matter hereof, and may not be modified
adversely to the Purchaser's interest except by means of a writing signed by the
Company and Purchaser.

         ----------------------------
has received, read and understood the Plan and the Option Agreement and agrees

Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a stockholder shall exist with
respect to the Optioned Stock, notwithstanding the exercise of the Option.  The
Company shall issue (or cause to be issued) such stock certificate promptly
after the Option is exercised.  No adjustment will be made for a dividend or
other right for which the record date is prior to the date the stock certificate

         Purchaser shall enjoy rights as a stockholder until such time as
Purchaser disposes of the Shares or the Company and/or its assignee(s) exercises
the Right of First Refusal hereunder.  Upon such exercise, Purchaser shall have
no further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser shall forthwith cause the certificate(s)
evidencing the Shares so purchased to be surrendered to the Company for transfer
or cancellation.

     4.  Company's Right of First Refusal.  Before any Shares held by Purchaser
         --------------------------------
or any transferee (either being sometimes referred to herein as the "Holder")
may be sold or otherwise transferred (including transfer by gift or operation of
law), the Company or its assignee(s) shall have a right of first refusal to
purchase the Shares on the terms and conditions set forth in this Section (the
"Right of First Refusal").

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

         (b) Exercise of Right of First Refusal.  At any time within thirty
             ----------------------------------
(30) days after receipt of the Notice, the Company and/or its assignee(s) may,
by giving written notice to the Holder, elect to purchase all, but not less than
all, of the Shares proposed to be transferred to any one or more of the Proposed
Transferees, at the purchase price determined in accordance with subsection (c)
below.

         (c) Purchase Price.  The purchase price ("Purchase Price") for the
             --------------
Shares purchased by the Company or its assignee(s) under this Section shall be
the Offered Price.  If the Offered Price includes consideration other than cash,
the cash equivalent value of the non-cash consideration shall be determined by
the Board of Directors of the Company in good faith.

         (d) Payment.  Payment of the Purchase Price shall be made, at the
             -------
option of the Company or its assignee(s), in cash (by check), by cancellation of
all or a portion of any outstanding indebtedness of the Holder to the Company
(or, in the case of repurchase by an assignee, to the assignee), or by any
combination thereof within 30 days after receipt of the Notice or in the manner
and at the times set forth in the Notice.

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

         (f) Exception for Certain Family Transfers.  Anything to the contrary
             --------------------------------------
contained in this Section notwithstanding, the transfer of any or all of the
Shares during the Purchaser's lifetime or on the Purchaser's death by will or
intestacy to the Purchaser's immediate family or a trust for the benefit of the
Purchaser's immediate family shall be exempt from the provisions of this
Section.  "Immediate Family" as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister.  In such case, the transferee
or other recipient shall receive and hold the Shares so transferred subject to
the provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

         (g) Termination of Right of First Refusal.  The Right of First Refusal

filed with and declared effective by the Securities and Exchange Commission
under the Securities Act of 1933, as amended, or (ii) a merger of the Company
with a corporation whose stock is publicly traded on a national exchange.

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

disposition of the Shares and that Purchaser is not relying on the Company for
any tax advice.

     6.  Restrictive Legends; Stop-Transfer Orders; Market Standoff.
         ----------------------------------------------------------

         (a) Legends. Purchaser understands and agrees that the Company shall
             -------
cause the legends set forth below or legends substantially equivalent thereto,
to be placed upon any certificate(s) evidencing ownership of the Shares together
with any other legends that may be required by the Company or by state or

             SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR
             TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

             ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN AN AGREEMENT BETWEEN THE
             ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY
             BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER
             RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES
             OF THESE SHARES.

             (b) Stop-Transfer Notices. Purchaser agrees that, in order to

issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate

             (c) Market Standoff.  Purchaser hereby agrees that if so requested
                 ---------------
by the Company or any representative of the underwriters in connection with any
registration of the offering of any securities of the Company under the
Securities Act of 1933, as amended (the "Securities Act"), neither Purchaser nor
                                         --------------
Purchaser shall sell or otherwise transfer any Shares or other securities of the
Company during such period as the Company and the representatives of the
underwriters may request (not to exceed 180 days) following the effective date
of any registration statement of the Company filed under the Securities Act for
an underwritten public offering. The Company may impose stop-transfer
instructions with respect to Shares subject to the foregoing restrictions until
the end of such market standoff period.

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

     7.  Successors and Assigns.  The Company may assign any of its rights under
         ----------------------

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

such a dispute by the Board or committee shall be final and binding on the
Company and on Purchaser.

     9.  Governing Law; Severability.  This Agreement shall be governed by and
         ---------------------------
construed in accordance with the laws of the State of California excluding that
body of law pertaining to conflicts of law.  Should any provision of this
Agreement be determined by a court of law to be illegal or unenforceable, the
other provisions shall nevertheless remain effective and shall remain
enforceable.

     10.  Notices.  Any notice required or permitted hereunder shall be given in
          -------
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States mail by certified mail, with postage and fees
prepaid, addressed to the other party at its address as shown below beneath its

SECURITY:    ___________ shares of Common Stock

AMOUNT:      __________________________________

DATE:        __________________________________


     In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

     (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities.  Purchaser is
acquiring these Securities for investment for Purchaser's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

     (b) Purchaser acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.  In this connection, Purchaser
understands that, in the view of the Securities and Exchange Commission, the
statutory basis for such exemption may be unavailable if Purchaser's
representation was predicated solely upon a present intention to hold these
Securities for the minimum capital gains period specified under tax statutes,
for a deferred sale, for or until an increase or decrease in the market price of
the Securities, or for a period of one year or any other fixed period in the
future.  Purchaser further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available.  Purchaser further
acknowledges and understands that the Company is under no obligation to register
the Securities.  Purchaser understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities unless they are registered or such registration is not required in
the opinion of counsel satisfactory to the Company and any other legend required
under applicable state securities laws.

     (c) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions.  Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Option to the Purchaser, the exercise will
be exempt from registration under the Securities Act.  In the event the Company
becomes subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer
period as any market stand-off agreement may require) the Securities exempt
under Rule 701 may be resold, subject to the satisfaction of certain of the
conditions specified by Rule 144, including:  (1) the resale being made through
a broker in an unsolicited "broker's transaction" or in transactions directly
with a market maker (as said term is defined under the Securities Exchange Act
of 1934); and, in the case of an affiliate, (2) the availability of certain
public information about the Company, (3) the amount of Securities being sold
during any three month period not exceeding the limitations specified in Rule
144(e), and (4) the timely filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than one year after the later of the date the Securities were
sold by the Company or the date the Securities were sold by an affiliate of the
Company, within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than two years, the satisfaction of the conditions set forth in
sections (1), (2), (3) and (4) of the paragraph immediately above.

     (d) Purchaser hereby agrees that if so requested by the Company or any
representative of the underwriters in connection with any registration of the
offering of any securities of the Company under the Securities Act, Purchaser
shall not sell or otherwise transfer any Shares or other securities of the
Company during the 180-day period following the effective date of a registration
statement of the Company filed under the Securities Act; provided, however, that
such restriction shall only apply to the first registration statement of the
Company to become effective under the Securities Act which include securities to
be sold on behalf of the Company to the public in an underwritten public
offering under the Securities Act.  The Company may impose stop-transfer
instructions with respect to securities subject to the foregoing restrictions
until the end of such 180-day period.
<PAGE>

     (e) Purchaser further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk.  Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

                                               Signature of Purchaser:

                                               ______________________________

   b.  Exercise of Option.  This Option shall be exercisable during its term in
       ------------------
accordance with the Vesting Schedule set out in the Notice of Grant and with the
provisions of Section 9 of the Plan as follows:

      (i) Right to Exercise.  (a) This Option may be exercised in whole or in
          -----------------
part at any time after the Date of Grant, as to Shares which have not yet vested

provided, however, that Optionee shall execute as a condition to such exercise
- --------  -------
of this Option, the Early Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit A (the "Early Exercise Agreement").  If
                             ---------       ------------------------
Optionee chooses to exercise this Option solely as to Shares which have vested
under the vesting schedule indicated on the Notice of Stock Option Grant,
Optionee shall complete and execute the form of Exercise Notice attached hereto
as Exhibit B (the "Exercise Agreement").  Notwithstanding the foregoing, the
   ---------       ------------------
Company may in its discretion prescribe or accept a different form of notice of
exercise and/or stock purchase agreement if such forms are otherwise consistent
with this Agreement, the Plan and then-applicable law.  (b) This Option may not
be exercised for a fraction of a Share. (c) In the event of Optionee's death,
Disability or other termination of the Optionee's Continuous Status as an

      (ii) Method of Exercise.  This Option shall be exercisable by execution
           ------------------
and delivery of the Early Exercise Agreement or the Exercise Agreement,
whichever is applicable, or of any other written notice approved for such
purpose by the Company which shall state the election to exercise the Option,
the number of Shares in respect of which the Option is being exercised, and such
other representations and agreements as to the holder's investment intent with
respect to such shares of Common Stock as may be required by the Company
pursuant to the provisions of the Plan.  Such written notice shall be signed by
the Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The written notice shall be accompanied by payment of
the Exercise Price.  This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

      No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of law and
the requirements of any stock exchange or national market system upon which the
Common Stock is then listed.  Assuming such compliance, for income tax purposes
the Shares shall be considered transferred to the Optionee on the date on which
the Option is exercised with respect to such Shares.

   c.  Optionee's Representations.  In the event the Shares purchasable pursuant
       --------------------------
to the exercise of this Option have not been registered under the Securities Act
of 1933, as amended, at the time this Option is exercised, Optionee shall, if
required by the Company, concurrently with the exercise of all or any portion of
this Option, deliver to the Company his or her Investment Representation
Statement in the form attached hereto as Exhibit C.

   d.  Lock-Up Period.  Optionee hereby agrees that if so requested by the
       --------------
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
longer period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act; provided, however, that such restriction shall apply only  to
the first registration statement of the Company to become effective under the
Securities Act that includes securities to be sold on behalf of the Company to
the public in an underwritten public offering under the Securities Act.  The
Company may impose stop-transfer instructions with respect to securities subject
to the foregoing restrictions until the end of such Market Standoff Period.

   e.  Method of Payment.  Payment of the Exercise Price shall be by any of the
       -----------------
following, or a combination thereof, at the election of the Optionee:

       (i)   cash; or

       (ii)  check; or

       (iii) surrender of other shares of Common Stock of the Company which (A)
in the case of Shares acquired pursuant to the exercise of a Company option,
have been owned by the Optionee for more than six (6) months on the date of
surrender, and (B) have a Fair Market Value on the date of surrender equal to
the Exercise Price of the Shares as to which the Option is being exercised; or

       (iv)  to the extent authorized by the Company, delivery of a properly
executed exercise notice together with such other documentation as the
Administrator and the broker, if applicable, share require to effect an exercise
of the Option and delivery to the Company of the sale or loan proceeds required
to pay the Exercise Price; or

       (v)   promissory note (in the form provided by the Company).

   f.  Restrictions on Exercise.  This Option may not be exercised if the
       ------------------------
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the
Federal Reserve Board.  As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

   g.  Termination of Relationship.  In the event an Optionee's Continuous
       ---------------------------
Status as an Employee, Consultant or Director terminates, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "Termination
Date"), exercise this Option during the Termination Period set out in the Notice
of Grant.  To the extent that Optionee was not entitled to exercise this Option
at the date of such termination, or if Optionee does not exercise this Option
within the time specified herein, the Option shall terminate.

   h.  Disability of Optionee.  Notwithstanding the provisions of Section g.
       ----------------------
above, in the event of termination of an Optionee's Continuous Status as an
Employee, Consultant or Director as a result of his or her Disability, Optionee
may, but only within twelve (12) months from the date of such termination (and
in no event later than the expiration date of the term of such Option as set
forth in the Notice of Grant) exercise the Option to the extent otherwise
entitled to exercise it at the date of such termination.  To the extent that
Optionee is not entitled to exercise the Option at the date of termination, or
if Optionee does not exercise such Option to the extent so entitled within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

   i.  Death of Optionee.  In the event of termination of Optionee's Continuous
       -----------------
Status as an Employee or Consultant as a result of the death of Optionee, the
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the date of expiration of the term of this
Option as set forth in Section k. below), by Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent the Optionee could exercise the Option at the date of death.

   j.  Non-Transferability of Option.  Options may not be sold, pledged,
       -----------------------------
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.  The terms of this Option shall
be binding upon the executors, administrators, heirs, successors and assigns of
the Optionee.

   k.  Term of Option.  This Option may be exercised only within the term set
       --------------
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.  The limitations set out
in Section 7 of the Plan regarding Options granted to more than ten percent
(10%) shareholders shall apply to this Option.

   l.  Tax Consequences.  Set forth below is a brief summary as of the date of
       ----------------
this Option of some of the federal tax consequences of exercise of this Option
and disposition of the Shares.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE
TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

      (i) Exercise of an NSO.  There may be a regular federal income tax
          ------------------
liability upon the exercise of an NSO.  The Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price.  In the case of the exercise of Option Shares which
have not vested as of the date of exercise, the Optionee will not realize
compensation income on the exercise until the date(s) on which shares vest
(i.e., have been released from the Company's repurchase option) unless the
Optionee files an election under Section 83(b) of the Code (an "83(b)
Election").  If an 83(b) election is filed, the amount of compensation income
will be determined on the date of exercise.  If Optionee is an Employee, the
Company will be required to withhold from Optionee's compensation or collect
from Optionee and pay to the applicable taxing authorities an amount equal to a
percentage of this compensation income at the time of exercise or vesting, as
applicable.

      (ii) Disposition of Shares.  If Shares are held for more than one year
           ---------------------
after the date of exercise (or the date of vesting, if later, in the case of the
exercise of unvested option shares and the Optionee had not filed an 83(b)
election at the time of such exercise, any gain realized on disposition of the
Shares will be treated as long-term capital gain for federal income tax
purposes.

CrossWorlds Software, Inc.
577 Airport Boulevard, Suite 800
Burlingame, CA  94010-2024
Attention: Stock Administrator

     1.  Exercise of Option.  Effective as of today, ___________, _____, the
         ------------------
undersigned ("Purchaser") __________________ hereby elects to exercise
Purchaser's option to purchase _________ shares of the Common Stock (the
"Shares") of CrossWorlds Software, Inc. (the "Company") under and pursuant to
the CrossWorlds Software , Inc., 1999 Executive Stock Plan, as amended (the
"Plan") and the Stock Option  Agreement dated _____________________________ (the
"Option Agreement").  Of these Shares, Purchaser has elected to purchase
_______________ of those Shares which have become vested as of the date hereof
under the Vesting Schedule set forth in the Notice of Stock Option Grant (the

"Vested Shares") and _____________ Shares which have not yet vested under such
- --------------
Vesting Schedule (the "Unvested Shares").  The purchase price for the Shares
                       ---------------
shall be $______ per Share for a total purchase price of $_______________.
The term "Shares" refers to the purchased Shares and all
          ------
securities received in replacement of the Shares or as stock dividends or
splits, all securities received in replacement of the Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of the Shares.

     2.  Representations of Purchaser.  Purchaser acknowledges that Purchaser
         ----------------------------
has received, read and understood the Plan and the Option Agreement and agrees
to abide by and be bound by their terms and conditions.

     3.  Rights as Stockholder.  Until the stock certificate evidencing such
         ---------------------
Shares is issued (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a stockholder shall exist with
respect to the Optioned Stock, notwithstanding the exercise of the Option.  The
Company shall issue (or cause to be issued) such stock certificate promptly
after the Option is exercised.  No adjustment will be made for a dividend or
other right for which the record date is prior to the date the stock certificate
is issued, except as provided in Section 12 of the Plan.

          Purchaser shall enjoy rights as a stockholder until such time as
Purchaser disposes of the Shares or the Company and/or its assignee(s) exercises
the Right of First Refusal hereunder.  Upon such exercise, Purchaser shall have
no further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser shall forthwith cause the certificate(s)
evidencing the Shares so purchased to be surrendered to the Company for transfer
or cancellation.

     4.  Limitations on Transfer.  In addition to any other limitation on
         -----------------------
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares while the Shares are subject
to the Company's Repurchase Option (as defined below).  After any Shares have
been released from such Repurchase Option, Purchaser shall not assign, encumber
or dispose of any interest in such Shares except in compliance with the
provisions below and applicable securities laws.

          (a)  Repurchase Option.
               -----------------

               (i) If Purchaser's Continuous Status as an Employee or Consultant
terminates for any reason (including for cause, death or disability), the
Company shall upon the date of such termination (the "Termination Date") have an
                                                      ----------------
irrevocable, exclusive option (the "Repurchase Option") for a period of 60 days
                                    -----------------
from such date to repurchase all or any portion of the Unvested Shares held by
Purchaser as of the Termination Date which have not yet been released from the
Company's Repurchase Option at the original purchase price per Share specified
in Section 1 (adjusted for any stock splits, stock dividends and the like).

               (ii) The Repurchase Option shall be exercised by the Company by
written notice to Purchaser or Purchaser's executor and, at the Company's
option, (A) by delivery to Purchaser or Purchaser's executor with such notice of
a check in the amount of the purchase price for the Shares being purchased, or
(B) in the event Purchaser is indebted to the Company, by cancellation by the
Company of an amount of such indebtedness equal to the purchase price for the
Shares being repurchased, or (C) by a combination of (A) and (B) so that the
combined payment and cancellation of indebtedness equals such purchase price.
Upon delivery of such notice and payment of the purchase price in any of the
ways described above, the Company shall become the legal and beneficial owner of
the Shares being repurchased and all rights and interest therein or related
thereto, and the Company shall have the right to transfer to its own name the
number of Shares being repurchased by the Company, without further action by
Purchaser.

               (iii)  One hundred percent (100%) of the Unvested Shares shall
initially be subject to the Repurchase Option.  The Unvested Shares shall be
released from the Repurchase Option in accordance with the Vesting Schedule set
forth in the Notice of Stock Option Grant
<PAGE>

until all Shares are released from the Repurchase Option. Fractional shares
shall be rounded to the nearest whole share.

          (b) Company's Right of First Refusal.  Before any Shares held by
              --------------------------------
Purchaser or any transferee (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section (the "Right of First Refusal").

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

               (ii)  Exercise of Right of First Refusal.  At any time within
                     ----------------------------------
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

               (iii) Purchase Price. The purchase price ("Purchase Price") for
                     --------------
the Shares purchased by the Company or its assignee(s) under this Section shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

               (iv)  Payment.  Payment of the Purchase Price shall be made, at
                     -------
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

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

               (vi) Exception for Certain Family Transfers.  Anything to the
                    --------------------------------------
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Purchaser's lifetime or on the Purchaser's death by
will or intestacy to the Purchaser's immediate family or a trust for the benefit
of the Purchaser's immediate family shall be exempt from the provisions of this
Section. "Immediate Family" as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister. In such case, the transferee
or other recipient shall receive and hold the Shares so transferred subject to
the provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

               (vii) Termination of Right of First Refusal.  The Right of First
                     -------------------------------------
Refusal shall terminate as to any Shares 90 days after the (i) first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the Securities and Exchange
Commission under the Securities Act of 1933, as amended, or (ii) a merger of the
Company with a corporation whose stock is publicly traded on a national
exchange.

     5.  Transfer of Shares; Escrow.
         --------------------------

         (a) Purchaser hereby authorizes and directs the Secretary of the
Company, or such other person designated by the Company, to transfer any
Unvested Shares as to which the Repurchase Option has been exercised from
Purchaser to the Company.

         (b) To ensure the availability for delivery of Purchaser's Unvested
Shares upon repurchase by the Company pursuant to the Repurchase Option under
Section 4(a), Purchaser hereby appoints Katrina A. Garnett of the Company, or
any other person designated by the Company, as escrow agent (the "Escrow Agent")
                                                                  ------------
and as Purchaser's attorney-in-fact to sell, assign and transfer unto the
Company such Unvested Shares, if any, as may be repurchased by the Company
pursuant to the Repurchase Option and shall, upon execution of this Agreement,
deliver and deposit with the Escrow Agent the share certificates representing
the Unvested Shares, together with two stock assignments duly endorsed in blank
and in the form attached hereto as Attachment A .  The Unvested Shares and stock
                                   ------------
assignment shall be held by the Escrow Agent in escrow pursuant to Joint Escrow
Instructions in the form attached hereto as Attachment B , until (i) the Company
                                            ------------
exercises its Repurchase Option as provided in Section 4(a), (ii) such Unvested
Shares become Vested Shares, or (iii) such time as this Agreement no longer is
in effect.  Upon vesting of the Unvested Shares, the Escrow Agent shall promptly
deliver to Purchaser the certificate or certificates representing such Shares in
the Escrow Agent's
<PAGE>

possession belonging to Purchaser, and the Escrow Agent shall be discharged of
all further obligations hereunder. Notwithstanding any of the foregoing,
however, the Escrow Agent shall nevertheless retain such certificate or
certificates as Escrow Agent if so required pursuant to other restriction
imposed pursuant to this Agreement.

          (c) The Escrow Agent shall not be liable for any act it may do or omit
to do with respect to holding the Shares in escrow and while acting in good
faith and in the exercise of its judgment.

          (d) Transfer or sale of the Shares is subject to restrictions on
transfer imposed by any applicable state and federal securities laws.  Any
transferee shall hold such Shares subject to all the provisions hereof and shall
acknowledge the same by signing a copy of this Agreement.

          (e) No Shares may be sold, pledged, hypothecated or otherwise
transferred by Purchaser until such Shares have become Vested Shares and are no
longer subject to any security agreement for the benefit of the Company.

     6.   Ownership, Voting Rights, Duties.  This Agreement shall not affect in
          --------------------------------
any way the ownership, voting rights or other rights or duties of Purchaser,
except as specifically provided herein.  Purchaser shall enjoy rights as a
stockholder until such time as Purchaser disposes of the Shares or the Company
and/or its assignee(s) exercises either the Repurchase Option or the Right of
First Refusal hereunder.  Upon any such exercise, Purchaser shall have no
further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser or the Escrow Agent, as the case may be, shall
forthwith cause the certificate(s) evidencing the Shares so purchased to be
surrendered to the Company for transfer or cancellation.

     7.   Tax Consultation.  Purchaser understands that Purchaser may suffer
          ----------------
adverse tax consequences as a result of Purchaser's purchase or disposition of
the Shares.  Purchaser represents that Purchaser has consulted with any tax
consultants Purchaser deems advisable in connection with the purchase or
disposition of the Shares and that Purchaser is not relying on the Company for
any tax advice.

     8.   Restrictive Legends; Stop-Transfer Orders; Market Standoff
          ----------------------------------------------------------

          (a) Legends.  Purchaser understands and agrees that the Company shall
              -------
cause the legends set forth below or legends substantially equivalent thereto,
to be placed upon any certificate(s) evidencing ownership of the Shares together
with any other legends that may be required by the Company or by state or
federal securities laws:

              THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
              THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
              SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
              UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY
              COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH
              OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
              THEREWITH.

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

          (b) Stop-Transfer Notices.  Purchaser agrees that, in order to ensure
              ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company  transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (c) Market Standoff.  Purchaser hereby agrees that if so requested by
              ---------------
the Company or any representative of the underwriters in connection with any
registration of the offering of any securities of the Company under the
Securities Act of 1933, as amended (the "Securities Act"), neither Purchaser nor
                                         --------------
Purchaser shall sell or otherwise transfer any Shares or other securities of the
Company during such period as the Company and the representatives of the
underwriters may request (not to exceed 180 days) following the effective date
of any registration statement of the Company filed under the Securities Act for
an underwritten public offering. The Company may impose stop-transfer
instructions with respect to Shares subject to the foregoing restrictions until
the end of such market standoff period.

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

     9.  Section 83(b) Election.  Purchaser understands that Section 83(a) of
         ----------------------
the Internal Revenue Code of 1986, as amended (the
<PAGE>

"Code"), taxes as ordinary income for a [Nonstatutory] [Incentive] Stock Option
the difference between the amount paid for the Shares and the Fair Market Value
of the Shares as of the date any restrictions on the Shares lapse. In this
context, "restriction" means the right of the Company to buy back the Shares
          -----------
pursuant to the Repurchase Option set forth in Section 4(a) of this Agreement.
Purchaser understands that Purchaser may elect to be taxed at the time the
Shares are purchased, rather than when and as the Repurchase Option expires, by
filing an election under Section 83(b) (an "83(b) Election") of the Code with
                                            --------------
the Internal Revenue Service within 30 days from the date of purchase. Even if
the Fair Market Value of the Shares at the time of the execution of this
Agreement equals the amount paid for the Shares, the election must be made to
avoid income tax treatment under Section 83(a) in the future. Purchaser
acknowledge that it is Purchaser's sole responsibility and not the Company's to
timely file the 83(b) Election, even if Purchaser requests the Company or its
representative to make this filing on Purchaser's behalf. Purchaser understands
that failure to file such an election in a timely manner may result in adverse
tax consequences for Purchaser. Purchaser further understands that an additional
copy of such election form should be filed with his or her federal income tax
return for the calendar year in which the date of this Agreement falls.
Purchaser acknowledges that the foregoing is only a summary of the effect of
United States federal income taxation with respect to purchase of the Shares
hereunder, and does not purport to be complete. Purchaser further acknowledges
that the Company has directed Purchaser to seek independent advice regarding the
applicable provisions of the Code, the income tax laws of any municipality,
state or foreign country in which Purchaser may reside, and the tax consequences
of Purchaser's death.

          Purchaser agrees that he or she will execute and deliver to the
Company with this executed Agreement a copy of the Acknowledgment and Statement
of Decision Regarding Section 83(b) Election (the "Acknowledgment") attached
                                                   --------------
hereto as Attachment C.  Purchaser further agrees that he or she will execute
          ------------
and submit with the Acknowledgment a copy of the 83(b) Election attached hereto
as Attachment D (for tax purposes in connection with the early exercise of an
   ------------
option) if Purchaser has indicated in the Acknowledgment his or her decision to
make such an election.

     10.  Notices.  All notices and other communications required or permitted
          -------
hereunder shall be in writing, shall be effective when given, and shall in any
event be deemed to be given (a) five (5) days after the deposit with the U.S.
Postal Service, if delivered by first class mail, postage prepaid (b) upon
delivery, if delivered by hand, or (c) one business day after the business day
of deposit with Federal Express or similar overnight courier, freight prepaid,
and shall be addressed (i) if to Purchaser, at Purchaser's address as set forth
beneath Purchaser's signature to this Agreement, or at such other address as
Purchaser shall have furnished to the Company in writing, (ii) if to the
Company, to CrossWorlds Software, Inc., with copy to Venture Law Group, 2775
Sand Hill Road, Menlo Park, California 94025, Attention:  Jon E. Gavenman, Esq.,
or Katrina A. Garnett, at CrossWorlds Software, Inc., or at such other address
as the Escrow Agent shall have furnished to the parties.

     11.  Successors and Assigns.  The Company may assign any of its rights
          ----------------------
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company.  Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Purchaser and his or her heirs, executors, administrators, successors and
assigns.

     12.  Interpretation.  Any dispute regarding the interpretation of this

Offered Price or at a higher price, provided that such sale or other transfer is
consummated within 120 days after the date of the Notice and provided further
that any such sale or other transfer is effected in accordance with any
applicable securities laws and the Proposed Transferee agrees in writing that
the provisions of this Section shall continue to apply to the Shares in the
hands of such Proposed Transferee.  If the Shares described in the Notice are
not transferred to the Proposed Transferee within such period, a new Notice
shall be given to the Company, and the Company and/or its assignees shall again
be offered the Right of First Refusal before any Shares held by the Holder may
be sold or otherwise transferred.

         (f) Exception for Certain Family Transfers.  Anything to the contrary
             --------------------------------------

Shares during the Purchaser's lifetime or on the Purchaser's death by will or
intestacy to the Purchaser's immediate family or a trust for the benefit of the
Purchaser's immediate family shall be exempt from the provisions of this
Section.  "Immediate Family" as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister.  In such case, the transferee
or other recipient shall receive and hold the Shares so transferred subject to
the provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

         (g) Termination of Right of First Refusal.  The Right of First Refusal
             -------------------------------------

Stock of the Company to the general public pursuant to a registration statement
filed with and declared effective by the Securities and Exchange Commission
under the Securities Act of 1933, as amended, or (ii) a merger of the Company
with a corporation whose stock is publicly traded on a national exchange.

         ----------------
adverse tax consequences as a result of Purchaser's purchase or disposition of

any tax advice.

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

         (a) Legends. Purchaser understands and agrees that the Company shall
             -------
cause the legends set forth below or legends substantially equivalent thereto,
to be placed upon any certificate(s) evidencing ownership of the Shares together
with any other legends that may be required by the Company or by state or

             SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH OFFER, SALE OR
             TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE THEREWITH.

             RESTRICTIONS ON TRANSFER AND A RIGHT OF FIRST REFUSAL HELD BY THE
             ISSUER OR ITS ASSIGNEE(S) AS SET FORTH IN AN AGREEMENT BETWEEN THE
             ISSUER AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY
             BE OBTAINED AT THE PRINCIPAL OFFICE OF THE ISSUER. SUCH TRANSFER
             RESTRICTIONS AND RIGHT OF FIRST REFUSAL ARE BINDING ON TRANSFEREES
             OF THESE SHARES.

             (b) Stop-Transfer Notices. Purchaser agrees that, in order to

issue appropriate "stop transfer" instructions to its transfer agent, if any,
and that, if the Company transfers its own securities, it may make appropriate

             (c) Market Standoff.  Purchaser hereby agrees that if so requested
                 ---------------
by the Company or any representative of the underwriters in connection with any
registration of the offering of any securities of the Company under the
Securities Act of 1933, as amended (the "Securities Act"), neither Purchaser nor
                                         --------------
Purchaser shall sell or otherwise transfer any Shares or other securities of the
Company during such period as the Company and the representatives of the
underwriters may request (not to exceed 180 days) following the effective date
of any registration statement of the Company filed under the Securities Act for
an underwritten public offering. The Company may impose stop-transfer
instructions with respect to Shares subject to the foregoing restrictions until
the end of such market standoff period.

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

     7.  Successors and Assigns.  The Company may assign any of its rights under
         ----------------------
this Agreement to single or multiple assignees, and this Agreement shall inure
to the benefit of the successors and assigns of the Company.  Subject to the
restrictions on transfer herein set forth, this Agreement shall be binding upon
Purchaser and his or her heirs, executors, administrators, successors and
assigns.

     8.  Interpretation.  Any dispute regarding the interpretation of this
         --------------
Agreement shall be submitted by Purchaser or by the Company forthwith to the
Company's Board of Directors or the committee thereof that administers the Plan,
which shall review such dispute at its next regular meeting.  The resolution of
such a dispute by the Board or committee shall be final and binding on the
Company and on Purchaser.

     9.  Governing Law; Severability.  This Agreement shall be governed by and
         ---------------------------
construed in accordance with the laws of the State of California excluding that
body of law pertaining to conflicts of law.  Should any provision of this
Agreement be determined by a court of law to be illegal or unenforceable, the
other provisions shall nevertheless remain effective and shall remain
enforceable.

     10.  Notices.  Any notice required or permitted hereunder shall be given in
          -------
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States mail by certified mail, with postage and fees
prepaid, addressed to the other party at its address as shown below beneath its

                      INVESTMENT REPRESENTATION STATEMENT


PURCHASER:   _____________________

COMPANY:     CROSSWORLDS SOFTWARE, INC.

SECURITY:    ___________ shares of Common Stock

AMOUNT:      __________________________________

DATE:        __________________________________


     In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

     (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities.  Purchaser is
acquiring these Securities for investment for Purchaser's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

     (b) Purchaser acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.  In this connection, Purchaser
understands that, in the view of the Securities and Exchange Commission, the
statutory basis for such exemption may be unavailable if Purchaser's
representation was predicated solely upon a present intention to hold these
Securities for the minimum capital gains period specified under tax statutes,
for a deferred sale, for or until an increase or decrease in the market price of
the Securities, or for a period of one year or any other fixed period in the
future.  Purchaser further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available.  Purchaser further
acknowledges and understands that the Company is under no obligation to register
the Securities.  Purchaser understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities unless they are registered or such registration is not required in
the opinion of counsel satisfactory to the Company and any other legend required
under applicable state securities laws.

     (c) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions.  Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Option to the Purchaser, the exercise will
be exempt from registration under the Securities Act.  In the event the Company
becomes subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer
period as any market stand-off agreement may require) the Securities exempt
under Rule 701 may be resold, subject to the satisfaction of certain of the
conditions specified by Rule 144, including:  (1) the resale being made through
a broker in an unsolicited "broker's transaction" or in transactions directly
with a market maker (as said term is defined under the Securities Exchange Act
of 1934); and, in the case of an affiliate, (2) the availability of certain
public information about the Company, (3) the amount of Securities being sold
during any three month period not exceeding the limitations specified in Rule
144(e), and (4) the timely filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than one year after the later of the date the Securities were
sold by the Company or the date the Securities were sold by an affiliate of the
Company, within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than two years, the satisfaction of the conditions set forth in
sections (1), (2), (3) and (4) of the paragraph immediately above.

     (d) Purchaser hereby agrees that if so requested by the Company or any
representative of the underwriters in connection with any registration of the
offering of any securities of the Company under the Securities Act, Purchaser
shall not sell or otherwise transfer any Shares or other securities of the
Company during the 180-day period following the effective date of a registration
statement of the Company filed under the Securities Act; provided, however, that
such restriction shall only apply to the first registration statement of the
Company to become effective under the Securities Act which include securities to
be sold on behalf of the Company to the public in an underwritten public
offering under the Securities Act.  The Company may impose stop-transfer
instructions with respect to securities subject to the foregoing restrictions
until the end of such 180-day period.
<PAGE>

     (e) Purchaser further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk.  Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

                                               Signature of Purchaser:

1. TERMS AND CONDITIONS OF GRANT

   a.  Grant of Option.  CrossWorlds Software, Inc. (the "Company"), hereby
       ----------------
grants to the Optionee (the "Optionee") named in the Notice of Grant, a

at the exercise price per share set forth in the Notice of Grant (the "Exercise

Unless otherwise defined herein, the terms defined in the Plan shall have the
same defined meanings in this Option Agreement.

   b.  Exercise of Option.  This Option shall be exercisable during its term in
       ------------------
accordance with the Vesting Schedule set out in the Notice of Grant and with the
provisions of Section 9 of the Plan as follows:

      (i) Right to Exercise.  (a) This Option may be exercised in whole or in
          -----------------
part at any time after the Date of Grant, as to Shares which have not yet vested
under the vesting schedule indicated on the Notice of Stock Option Grant;

provided, however, that Optionee shall execute as a condition to such exercise
- --------  -------
of this Option, the Early Exercise Notice and Restricted Stock Purchase
Agreement attached hereto as Exhibit A (the "Early Exercise Agreement").  If
                             ---------       ------------------------
Optionee chooses to exercise this Option solely as to Shares which have vested
under the vesting schedule indicated on the Notice of Stock Option Grant,
Optionee shall complete and execute the form of Exercise Notice attached hereto
as Exhibit B (the "Exercise Agreement").  Notwithstanding the foregoing, the
   ---------       ------------------
Company may in its discretion prescribe or accept a different form of notice of
exercise and/or stock purchase agreement if such forms are otherwise consistent
with this Agreement, the Plan and then-applicable law.  (b) This Option may not
be exercised for a fraction of a Share. (c) In the event of Optionee's death,
Disability or other termination of the Optionee's Continuous Status as an
Employee, Consultant or Director, the exercisability of the Option is governed

below.  (d) In no event may this Option be exercised after the date of
expiration of the term of this Option as set forth in the Notice of Grant.

      (ii) Method of Exercise.  This Option shall be exercisable by execution
           ------------------
and delivery of the Early Exercise Agreement or the Exercise Agreement,
whichever is applicable, or of any other written notice approved for such
purpose by the Company which shall state the election to exercise the Option,
the number of Shares in respect of which the Option is being exercised, and such
other representations and agreements as to the holder's investment intent with
respect to such shares of Common Stock as may be required by the Company
pursuant to the provisions of the Plan.  Such written notice shall be signed by
the Optionee and shall be delivered in person or by certified mail to the
Secretary of the Company.  The written notice shall be accompanied by payment of
the Exercise Price.  This Option shall be deemed to be exercised upon receipt by
the Company of such written notice accompanied by the Exercise Price.

      No Shares will be issued pursuant to the exercise of an Option unless such
issuance and such exercise shall comply with all relevant provisions of law and
the requirements of any stock exchange or national market system upon which the
Common Stock is then listed.  Assuming such compliance, for income tax purposes
the Shares shall be considered transferred to the Optionee on the date on which
the Option is exercised with respect to such Shares.

   c.  Optionee's Representations.  In the event the Shares purchasable pursuant
       --------------------------
to the exercise of this Option have not been registered under the Securities Act
of 1933, as amended, at the time this Option is exercised, Optionee shall, if
required by the Company, concurrently with the exercise of all or any portion of
this Option, deliver to the Company his or her Investment Representation
Statement in the form attached hereto as Exhibit C.

   d.  Lock-Up Period.  Optionee hereby agrees that if so requested by the
       --------------
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
longer period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act; provided, however, that such restriction shall apply only  to
the first registration statement of the Company to become effective under the
Securities Act that includes securities to be sold on behalf of the Company to
the public in an underwritten public offering under the Securities Act.  The
Company may impose stop-transfer instructions with respect to securities subject
to the foregoing restrictions until the end of such Market Standoff Period.

   e.  Method of Payment.  Payment of the Exercise Price shall be by any of the
       -----------------
following, or a combination thereof, at the election of the Optionee:

       (i)   cash; or

       (ii)  check; or

       (iii) surrender of other shares of Common Stock of the Company which (A)
in the case of Shares acquired pursuant to the exercise of a Company option,
have been owned by the Optionee for more than six (6) months on the date of
surrender, and (B) have a Fair Market Value on the date of surrender equal to
the Exercise Price of the Shares as to which the Option is being exercised; or

       (iv)  to the extent authorized by the Company, delivery of a properly
executed exercise notice together with such other documentation as the
Administrator and the broker, if applicable, share require to effect an exercise
of the Option and delivery to the Company of the sale or loan proceeds required
to pay the Exercise Price; or

       (v)   promissory note (in the form provided by the Company).

   f.  Restrictions on Exercise.  This Option may not be exercised if the
       ------------------------
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the
Federal Reserve Board.  As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

   g.  Termination of Relationship.  In the event an Optionee's Continuous
       ---------------------------
Status as an Employee, Consultant or Director terminates, Optionee may, to the
extent otherwise so entitled at the date of such termination (the "Termination
Date"), exercise this Option during the Termination Period set out in the Notice
of Grant.  To the extent that Optionee was not entitled to exercise this Option
at the date of such termination, or if Optionee does not exercise this Option
within the time specified herein, the Option shall terminate.

   h.  Disability of Optionee.  Notwithstanding the provisions of Section g.
       ----------------------
above, in the event of termination of an Optionee's Continuous Status as an
Employee, Consultant or Director as a result of his or her Disability, Optionee
may, but only within twelve (12) months from the date of such termination (and
in no event later than the expiration date of the term of such Option as set
forth in the Notice of Grant) exercise the Option to the extent otherwise
entitled to exercise it at the date of such termination.  To the extent that
Optionee is not entitled to exercise the Option at the date of termination, or
if Optionee does not exercise such Option to the extent so entitled within the
time specified herein, the Option shall terminate, and the Shares covered by
such Option shall revert to the Plan.

   i.  Death of Optionee.  In the event of termination of Optionee's Continuous
       -----------------
Status as an Employee or Consultant as a result of the death of Optionee, the
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the date of expiration of the term of this
Option as set forth in Section k. below), by Optionee's estate or by a person
who acquired the right to exercise the Option by bequest or inheritance, but
only to the extent the Optionee could exercise the Option at the date of death.

   j.  Non-Transferability of Option.  Options may not be sold, pledged,
       -----------------------------
assigned, hypothecated, transferred, or disposed of in any manner other than by
will or by the laws of descent or distribution and may be exercised, during the
lifetime of the Optionee, only by the Optionee.  The terms of this Option shall
be binding upon the executors, administrators, heirs, successors and assigns of
the Optionee.

   k.  Term of Option.  This Option may be exercised only within the term set
       --------------
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option.  The limitations set out
in Section 7 of the Plan regarding Options granted to more than ten percent
(10%) shareholders shall apply to this Option.

   l.  Tax Consequences.  Set forth below is a brief summary as of the date of
       ----------------
this Option of some of the federal tax consequences of exercise of this Option
and disposition of the Shares.  THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE
TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.  OPTIONEE SHOULD CONSULT A TAX
ADVISER BEFORE EXERCISING THIS OPTION OR DISPOSING OF THE SHARES.

      (i) Exercise of an NSO.  There may be a regular federal income tax
          ------------------
liability upon the exercise of an NSO.  The Optionee will be treated as having
received compensation income (taxable at ordinary income tax rates) equal to the
excess, if any, of the Fair Market Value of the Shares on the date of exercise
over the Exercise Price.  In the case of the exercise of Option Shares which
have not vested as of the date of exercise, the Optionee will not realize
compensation income on the exercise until the date(s) on which shares vest
(i.e., have been released from the Company's repurchase option) unless the
Optionee files an election under Section 83(b) of the Code (an "83(b)
Election").  If an 83(b) election is filed, the amount of compensation income
will be determined on the date of exercise.  If Optionee is an Employee, the
Company will be required to withhold from Optionee's compensation or collect
from Optionee and pay to the applicable taxing authorities an amount equal to a
percentage of this compensation income at the time of exercise or vesting, as
applicable.

      (ii) Disposition of Shares.  If Shares are held for more than one year
           ---------------------
after the date of exercise (or the date of vesting, if later, in the case of the
exercise of unvested option shares and the Optionee had not filed an 83(b)
election at the time of such exercise, any gain realized on disposition of the
Shares will be treated as long-term capital gain for federal income tax
purposes.

Attention: Stock Administrator

     1.  Exercise of Option.  Effective as of today, ___________, _____, the
         ------------------
undersigned ("Purchaser") __________________ hereby elects to exercise
Purchaser's option to purchase _________ shares of the Common Stock (the
"Shares") of CrossWorlds Software, Inc. (the "Company") under and pursuant to
the CrossWorlds Software , Inc., 1999 Executive Stock Plan, as amended (the
"Plan") and the Stock Option  Agreement dated _____________________________ (the
"Option Agreement").  Of these Shares, Purchaser has elected to purchase
_______________ of those Shares which have become vested as of the date hereof
under the Vesting Schedule set forth in the Notice of Stock Option Grant (the

"Vested Shares") and _____________ Shares which have not yet vested under such
- --------------
Vesting Schedule (the "Unvested Shares").  The purchase price for the Shares
                       ---------------
shall be $______ per Share for a total purchase price of $_______________.
The term "Shares" refers to the purchased Shares and all
          ------
securities received in replacement of the Shares or as stock dividends or
splits, all securities received in replacement of the Shares in a
recapitalization, merger, reorganization, exchange or the like, and all new,
substituted or additional securities or other properties to which Purchaser is
entitled by reason of Purchaser's ownership of the Shares.

     2.  Representations of Purchaser.  Purchaser acknowledges that Purchaser
         ----------------------------
has received, read and understood the Plan and the Option Agreement and agrees
to abide by and be bound by their terms and conditions.

     3.  Rights as Stockholder.  Until the stock certificate evidencing such
         ---------------------
Shares is issued (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a stockholder shall exist with
respect to the Optioned Stock, notwithstanding the exercise of the Option.  The
Company shall issue (or cause to be issued) such stock certificate promptly
after the Option is exercised.  No adjustment will be made for a dividend or
other right for which the record date is prior to the date the stock certificate
is issued, except as provided in Section 12 of the Plan.

          Purchaser shall enjoy rights as a stockholder until such time as
Purchaser disposes of the Shares or the Company and/or its assignee(s) exercises
the Right of First Refusal hereunder.  Upon such exercise, Purchaser shall have
no further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser shall forthwith cause the certificate(s)
evidencing the Shares so purchased to be surrendered to the Company for transfer
or cancellation.

     4.  Limitations on Transfer.  In addition to any other limitation on
         -----------------------
transfer created by applicable securities laws, Purchaser shall not assign,
encumber or dispose of any interest in the Shares while the Shares are subject
to the Company's Repurchase Option (as defined below).  After any Shares have
been released from such Repurchase Option, Purchaser shall not assign, encumber
or dispose of any interest in such Shares except in compliance with the
provisions below and applicable securities laws.

          (a)  Repurchase Option.
               -----------------

               (i) If Purchaser's Continuous Status as an Employee or Consultant
terminates for any reason (including for cause, death or disability), the
Company shall upon the date of such termination (the "Termination Date") have an
                                                      ----------------
irrevocable, exclusive option (the "Repurchase Option") for a period of 60 days
                                    -----------------
from such date to repurchase all or any portion of the Unvested Shares held by
Purchaser as of the Termination Date which have not yet been released from the
Company's Repurchase Option at the original purchase price per Share specified
in Section 1 (adjusted for any stock splits, stock dividends and the like).

               (ii) The Repurchase Option shall be exercised by the Company by
written notice to Purchaser or Purchaser's executor and, at the Company's
option, (A) by delivery to Purchaser or Purchaser's executor with such notice of
a check in the amount of the purchase price for the Shares being purchased, or
(B) in the event Purchaser is indebted to the Company, by cancellation by the
Company of an amount of such indebtedness equal to the purchase price for the
Shares being repurchased, or (C) by a combination of (A) and (B) so that the
combined payment and cancellation of indebtedness equals such purchase price.
Upon delivery of such notice and payment of the purchase price in any of the
ways described above, the Company shall become the legal and beneficial owner of
the Shares being repurchased and all rights and interest therein or related
thereto, and the Company shall have the right to transfer to its own name the
number of Shares being repurchased by the Company, without further action by
Purchaser.

               (iii)  One hundred percent (100%) of the Unvested Shares shall
initially be subject to the Repurchase Option.  The Unvested Shares shall be
released from the Repurchase Option in accordance with the Vesting Schedule set
forth in the Notice of Stock Option Grant
<PAGE>

until all Shares are released from the Repurchase Option. Fractional shares
shall be rounded to the nearest whole share.

          (b) Company's Right of First Refusal.  Before any Shares held by
              --------------------------------
Purchaser or any transferee (either being sometimes referred to herein as the
"Holder") may be sold or otherwise transferred (including transfer by gift or
operation of law), the Company or its assignee(s) shall have a right of first
refusal to purchase the Shares on the terms and conditions set forth in this
Section (the "Right of First Refusal").

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

               (ii)  Exercise of Right of First Refusal.  At any time within
                     ----------------------------------
thirty (30) days after receipt of the Notice, the Company and/or its assignee(s)
may, by giving written notice to the Holder, elect to purchase all, but not less
than all, of the Shares proposed to be transferred to any one or more of the
Proposed Transferees, at the purchase price determined in accordance with
subsection (c) below.

               (iii) Purchase Price. The purchase price ("Purchase Price") for
                     --------------
the Shares purchased by the Company or its assignee(s) under this Section shall
be the Offered Price. If the Offered Price includes consideration other than
cash, the cash equivalent value of the non-cash consideration shall be
determined by the Board of Directors of the Company in good faith.

               (iv)  Payment.  Payment of the Purchase Price shall be made, at
                     -------
the option of the Company or its assignee(s), in cash (by check), by
cancellation of all or a portion of any outstanding indebtedness of the Holder
to the Company (or, in the case of repurchase by an assignee, to the assignee),
or by any combination thereof within 30 days after receipt of the Notice or in
the manner and at the times set forth in the Notice.

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

               (vi) Exception for Certain Family Transfers.  Anything to the
                    --------------------------------------
contrary contained in this Section notwithstanding, the transfer of any or all
of the Shares during the Purchaser's lifetime or on the Purchaser's death by
will or intestacy to the Purchaser's immediate family or a trust for the benefit
of the Purchaser's immediate family shall be exempt from the provisions of this
Section. "Immediate Family" as used herein shall mean spouse, lineal descendant
or antecedent, father, mother, brother or sister. In such case, the transferee
or other recipient shall receive and hold the Shares so transferred subject to
the provisions of this Section, and there shall be no further transfer of such
Shares except in accordance with the terms of this Section.

               (vii) Termination of Right of First Refusal.  The Right of First
                     -------------------------------------
Refusal shall terminate as to any Shares 90 days after the (i) first sale of
Common Stock of the Company to the general public pursuant to a registration
statement filed with and declared effective by the Securities and Exchange
Commission under the Securities Act of 1933, as amended, or (ii) a merger of the
Company with a corporation whose stock is publicly traded on a national
exchange.

     5.  Transfer of Shares; Escrow.
         --------------------------

         (a) Purchaser hereby authorizes and directs the Secretary of the
Company, or such other person designated by the Company, to transfer any
Unvested Shares as to which the Repurchase Option has been exercised from
Purchaser to the Company.

         (b) To ensure the availability for delivery of Purchaser's Unvested
Shares upon repurchase by the Company pursuant to the Repurchase Option under
Section 4(a), Purchaser hereby appoints Katrina A. Garnett of the Company, or
any other person designated by the Company, as escrow agent (the "Escrow Agent")
                                                                  ------------
and as Purchaser's attorney-in-fact to sell, assign and transfer unto the
Company such Unvested Shares, if any, as may be repurchased by the Company
pursuant to the Repurchase Option and shall, upon execution of this Agreement,
deliver and deposit with the Escrow Agent the share certificates representing
the Unvested Shares, together with two stock assignments duly endorsed in blank
and in the form attached hereto as Attachment A .  The Unvested Shares and stock
                                   ------------
assignment shall be held by the Escrow Agent in escrow pursuant to Joint Escrow
Instructions in the form attached hereto as Attachment B , until (i) the Company
                                            ------------
exercises its Repurchase Option as provided in Section 4(a), (ii) such Unvested
Shares become Vested Shares, or (iii) such time as this Agreement no longer is
in effect.  Upon vesting of the Unvested Shares, the Escrow Agent shall promptly
deliver to Purchaser the certificate or certificates representing such Shares in
the Escrow Agent's
<PAGE>

possession belonging to Purchaser, and the Escrow Agent shall be discharged of
all further obligations hereunder. Notwithstanding any of the foregoing,
however, the Escrow Agent shall nevertheless retain such certificate or
certificates as Escrow Agent if so required pursuant to other restriction
imposed pursuant to this Agreement.

          (c) The Escrow Agent shall not be liable for any act it may do or omit
to do with respect to holding the Shares in escrow and while acting in good
faith and in the exercise of its judgment.

          (d) Transfer or sale of the Shares is subject to restrictions on
transfer imposed by any applicable state and federal securities laws.  Any
transferee shall hold such Shares subject to all the provisions hereof and shall
acknowledge the same by signing a copy of this Agreement.

          (e) No Shares may be sold, pledged, hypothecated or otherwise
transferred by Purchaser until such Shares have become Vested Shares and are no
longer subject to any security agreement for the benefit of the Company.

     6.   Ownership, Voting Rights, Duties.  This Agreement shall not affect in
          --------------------------------
any way the ownership, voting rights or other rights or duties of Purchaser,
except as specifically provided herein.  Purchaser shall enjoy rights as a
stockholder until such time as Purchaser disposes of the Shares or the Company
and/or its assignee(s) exercises either the Repurchase Option or the Right of
First Refusal hereunder.  Upon any such exercise, Purchaser shall have no
further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Purchaser or the Escrow Agent, as the case may be, shall
forthwith cause the certificate(s) evidencing the Shares so purchased to be
surrendered to the Company for transfer or cancellation.

     7.   Tax Consultation.  Purchaser understands that Purchaser may suffer
          ----------------
adverse tax consequences as a result of Purchaser's purchase or disposition of
the Shares.  Purchaser represents that Purchaser has consulted with any tax
consultants Purchaser deems advisable in connection with the purchase or
disposition of the Shares and that Purchaser is not relying on the Company for
any tax advice.

     8.   Restrictive Legends; Stop-Transfer Orders; Market Standoff
          ----------------------------------------------------------

          (a) Legends.  Purchaser understands and agrees that the Company shall
              -------
cause the legends set forth below or legends substantially equivalent thereto,
to be placed upon any certificate(s) evidencing ownership of the Shares together
with any other legends that may be required by the Company or by state or
federal securities laws:

              THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
              THE SECURITIES ACT OF 1933 (THE "ACT") AND MAY NOT BE OFFERED,
              SOLD OR OTHERWISE TRANSFERRED, PLEDGED OR HYPOTHECATED UNLESS AND
              UNTIL REGISTERED UNDER THE ACT OR, IN THE OPINION OF COMPANY
              COUNSEL SATISFACTORY TO THE ISSUER OF THESE SECURITIES, SUCH
              OFFER, SALE OR TRANSFER, PLEDGE OR HYPOTHECATION IS IN COMPLIANCE
              THEREWITH.

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

          (b) Stop-Transfer Notices.  Purchaser agrees that, in order to ensure
              ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company  transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (c) Market Standoff.  Purchaser hereby agrees that if so requested by
              ---------------
the Company or any representative of the underwriters in connection with any
registration of the offering of any securities of the Company under the
Securities Act of 1933, as amended (the "Securities Act"), neither Purchaser nor
                                         --------------
Purchaser shall sell or otherwise transfer any Shares or other securities of the
Company during such period as the Company and the representatives of the
underwriters may request (not to exceed 180 days) following the effective date
of any registration statement of the Company filed under the Securities Act for
an underwritten public offering. The Company may impose stop-transfer
instructions with respect to Shares subject to the foregoing restrictions until
the end of such market standoff period.

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

     9.  Section 83(b) Election.  Purchaser understands that Section 83(a) of
         ----------------------
the Internal Revenue Code of 1986, as amended (the
<PAGE>

"Code"), taxes as ordinary income for a [Nonstatutory] [Incentive] Stock Option
the difference between the amount paid for the Shares and the Fair Market Value
of the Shares as of the date any restrictions on the Shares lapse. In this
context, "restriction" means the right of the Company to buy back the Shares
          -----------
pursuant to the Repurchase Option set forth in Section 4(a) of this Agreement.
Purchaser understands that Purchaser may elect to be taxed at the time the
Shares are purchased, rather than when and as the Repurchase Option expires, by
filing an election under Section 83(b) (an "83(b) Election") of the Code with
                                            --------------
the Internal Revenue Service within 30 days from the date of purchase. Even if
the Fair Market Value of the Shares at the time of the execution of this
Agreement equals the amount paid for the Shares, the election must be made to
avoid income tax treatment under Section 83(a) in the future. Purchaser
acknowledge that it is Purchaser's sole responsibility and not the Company's to
timely file the 83(b) Election, even if Purchaser requests the Company or its
representative to make this filing on Purchaser's behalf. Purchaser understands
that failure to file such an election in a timely manner may result in adverse
tax consequences for Purchaser. Purchaser further understands that an additional
copy of such election form should be filed with his or her federal income tax
return for the calendar year in which the date of this Agreement falls.
Purchaser acknowledges that the foregoing is only a summary of the effect of
United States federal income taxation with respect to purchase of the Shares
hereunder, and does not purport to be complete. Purchaser further acknowledges
that the Company has directed Purchaser to seek independent advice regarding the
applicable provisions of the Code, the income tax laws of any municipality,
state or foreign country in which Purchaser may reside, and the tax consequences
of Purchaser's death.

          Purchaser agrees that he or she will execute and deliver to the
Company with this executed Agreement a copy of the Acknowledgment and Statement
of Decision Regarding Section 83(b) Election (the "Acknowledgment") attached
                                                   --------------
hereto as Attachment C.  Purchaser further agrees that he or she will execute
          ------------
and submit with the Acknowledgment a copy of the 83(b) Election attached hereto
as Attachment D (for tax purposes in connection with the early exercise of an
   ------------
option) if Purchaser has indicated in the Acknowledgment his or her decision to
make such an election.

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

Sand Hill Road, Menlo Park, California 94025, Attention:  Jon E. Gavenman, Esq.,

as the Escrow Agent shall have furnished to the parties.

     11.  Successors and Assigns.  The Company may assign any of its rights
          ----------------------
under this Agreement to single or multiple assignees, and this Agreement shall
inure to the benefit of the successors and assigns of the Company.  Subject to
the restrictions on transfer herein set forth, this Agreement shall be binding
upon Purchaser and his or her heirs, executors, administrators, successors and
assigns.

     12.  Interpretation.  Any dispute regarding the interpretation of this
          --------------
Agreement shall be submitted by Purchaser or by the Company forthwith to the
Company's Board of Directors or the committee thereof that administers the Plan,
which shall review such dispute at its next regular meeting.  The resolution of
such a dispute by the Board or committee shall be final and binding on the
Company and on Purchaser.

     13.  Governing Law; Severability.  This Agreement shall be governed by and
          ---------------------------
construed in accordance with the laws of the State of California excluding that
body of law pertaining to conflicts of law.  Should any provision of this
Agreement be determined by a court of law to be illegal or unenforceable, the
other provisions shall nevertheless remain effective and shall remain
enforceable.

     14.  Notices.  Any notice required or permitted hereunder shall be given in
          -------
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States mail by certified mail, with postage and fees
prepaid, addressed to the other party at its address as shown below beneath its
signature, or to such other address as such party may designate in writing from
time to time to the other party.

     15.  Further Instruments.  The parties agree to execute such further
          -------------------
instruments and to take such further action as may be reasonably necessary to
carry out the purposes and intent of this Agreement.

     16.  Delivery of Payment.  Purchaser herewith delivers to the Company the
          -------------------
full Exercise Price for the Shares.
<PAGE>

     17.  Entire Agreement.  The Plan and Notice of Grant/Option Agreement are
          ----------------
incorporated herein by reference.  This Agreement, the Plan, the Option
Agreement and the Investment Representation Statement constitute the entire
agreement of the parties with respect to the subject matter hereof and supersede
in their entirety all prior undertakings and agreements of the Company and
Purchaser with respect to the subject matter hereof, and may not be modified
adversely to the Purchaser's interest except by means of a writing signed by the
Company and Purchaser.

instructions with respect to Shares subject to the foregoing restrictions until
the end of such market standoff period.

             (d) Refusal to Transfer.  The Company shall not be required (i) to
                 -------------------

construed in accordance with the laws of the State of California excluding that
body of law pertaining to conflicts of law.  Should any provision of this

COMPANY:     CROSSWORLDS SOFTWARE, INC.

SECURITY:    ___________ shares of Common Stock

AMOUNT:      __________________________________

DATE:        __________________________________


     In connection with the purchase of the above-listed Securities, the
undersigned Purchaser represents to the Company the following:

     (a) Purchaser is aware of the Company's business affairs and financial
condition and has acquired sufficient information about the Company to reach an
informed and knowledgeable decision to acquire the Securities.  Purchaser is
acquiring these Securities for investment for Purchaser's own account only and
not with a view to, or for resale in connection with, any "distribution" thereof
within the meaning of the Securities Act of 1933, as amended (the "Securities
Act").

     (b) Purchaser acknowledges and understands that the Securities constitute
"restricted securities" under the Securities Act and have not been registered
under the Securities Act in reliance upon a specific exemption therefrom, which
exemption depends upon, among other things, the bona fide nature of Purchaser's
investment intent as expressed herein.  In this connection, Purchaser
understands that, in the view of the Securities and Exchange Commission, the
statutory basis for such exemption may be unavailable if Purchaser's
representation was predicated solely upon a present intention to hold these
Securities for the minimum capital gains period specified under tax statutes,
for a deferred sale, for or until an increase or decrease in the market price of
the Securities, or for a period of one year or any other fixed period in the
future.  Purchaser further understands that the Securities must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available.  Purchaser further
acknowledges and understands that the Company is under no obligation to register
the Securities.  Purchaser understands that the certificate evidencing the
Securities will be imprinted with a legend which prohibits the transfer of the
Securities unless they are registered or such registration is not required in
the opinion of counsel satisfactory to the Company and any other legend required
under applicable state securities laws.

     (c) Purchaser is familiar with the provisions of Rule 701 and Rule 144,
each promulgated under the Securities Act, which, in substance, permit limited
public resale of "restricted securities" acquired, directly or indirectly from
the issuer thereof, in a non-public offering subject to the satisfaction of
certain conditions.  Rule 701 provides that if the issuer qualifies under Rule
701 at the time of the grant of the Option to the Purchaser, the exercise will
be exempt from registration under the Securities Act.  In the event the Company
becomes subject to the reporting requirements of Section 13 or 15(d) of the
Securities Exchange Act of 1934, ninety (90) days thereafter (or such longer
period as any market stand-off agreement may require) the Securities exempt
under Rule 701 may be resold, subject to the satisfaction of certain of the
conditions specified by Rule 144, including:  (1) the resale being made through
a broker in an unsolicited "broker's transaction" or in transactions directly
with a market maker (as said term is defined under the Securities Exchange Act
of 1934); and, in the case of an affiliate, (2) the availability of certain
public information about the Company, (3) the amount of Securities being sold
during any three month period not exceeding the limitations specified in Rule
144(e), and (4) the timely filing of a Form 144, if applicable.

     In the event that the Company does not qualify under Rule 701 at the time
of grant of the Option, then the Securities may be resold in certain limited
circumstances subject to the provisions of Rule 144, which requires the resale
to occur not less than one year after the later of the date the Securities were
sold by the Company or the date the Securities were sold by an affiliate of the
Company, within the meaning of Rule 144; and, in the case of acquisition of the
Securities by an affiliate, or by a non-affiliate who subsequently holds the
Securities less than two years, the satisfaction of the conditions set forth in
sections (1), (2), (3) and (4) of the paragraph immediately above.

     (d) Purchaser hereby agrees that if so requested by the Company or any
representative of the underwriters in connection with any registration of the
offering of any securities of the Company under the Securities Act, Purchaser
shall not sell or otherwise transfer any Shares or other securities of the
Company during the 180-day period following the effective date of a registration
statement of the Company filed under the Securities Act; provided, however, that
such restriction shall only apply to the first registration statement of the
Company to become effective under the Securities Act which include securities to
be sold on behalf of the Company to the public in an underwritten public
offering under the Securities Act.  The Company may impose stop-transfer
instructions with respect to securities subject to the foregoing restrictions
until the end of such 180-day period.
<PAGE>

     (e) Purchaser further understands that in the event all of the applicable
requirements of Rule 701 or 144 are not satisfied, registration under the
Securities Act, compliance with Regulation A, or some other registration
exemption will be required; and that, notwithstanding the fact that Rules 144
and 701 are not exclusive, the Staff of the Securities and Exchange Commission
has expressed its opinion that persons proposing to sell private placement
securities other than in a registered offering and otherwise than pursuant to
Rules 144 or 701 will have a substantial burden of proof in establishing that an
exemption from registration is available for such offers or sales, and that such
persons and their respective brokers who participate in such transactions do so
at their own risk.  Purchaser understands that no assurances can be given that
any such other registration exemption will be available in such event.

                                               Signature of Purchaser:

                         CROSSWORLDS SOFTWARE, INC.

   Employment, Confidential Information and Invention Assignment Agreement

      As a condition of my employment with CrossWorlds Software, Inc., its
subsidiaries, affiliates, successors or assigns (together the "Company"), and in

with or without good cause or for any or no cause, at the option either of the
Company or myself, with or without notice.

          (b) I agree that, during the term of my employment with the Company, I
will not engage in any other employment, occupation, consulting or other
business activity directly related to the business in which the Company is now
involved or becomes involved during the term of my employment, nor will I engage
in any other activities that conflict with my obligations to the Company.

          (c) I agree to adhere to the Company's Conflict of Interest Guidelines
attached as Exhibit A hereto.
            ---------

      2.  Confidential Information.

          (a) Company Information.  I agree at all times during the term of my
              -------------------
employment and thereafter to hold in strictest confidence, and not to use except
for the benefit of the Company or to disclose to any person, firm or corporation
without written authorization of the Board of Directors of the Company, any
Confidential Information of the Company.  I understand that "Confidential
                                                             ------------
Information" means any Company proprietary information, technical data, trade
- -----------
secrets or know-how, including, but not limited to, research, product plans,
products, services, customer lists and customers (including, but not limited to,
customers of the Company on whom I called or with whom I became acquainted
during the term of my employment), markets, software, developments, inventions,
processes, formulas, technology, designs, drawings, engineering, hardware

become publicly known and

<PAGE>

made generally available through no wrongful act of mine or of others who were
under confidentiality obligations as to the item or items involved.

          (b) Former Employer Information.  I agree that I will not, during my
              ---------------------------
employment with the Company, improperly use or disclose any proprietary
information or trade secrets of any former or concurrent employer or other
person or entity and that I will not bring onto the premises of the Company any
unpublished document or proprietary information belonging to any such employer,
person or entity unless consented to in writing by such employer, person or
entity.

          (c) Third Party Information.  I recognize that the Company has
              -----------------------
received and in the future will receive from third parties their confidential or
proprietary information subject to a duty on the Company's part to maintain the
confidentiality of such information and to use it only for certain limited
purposes.  I agree to hold all such confidential or proprietary information in
the strictest confidence and not to disclose it to any person, firm or
corporation or to use it except as necessary in carrying out my work for the
Company consistent with the Company's agreement with such third party.

      3.  Inventions.
          -------------

          (a) Assignment of Inventions.  I agree that I will promptly make full
              ------------------------
written disclosure to the Company, will hold in trust for the sole right and
benefit of the Company, and hereby assign to the Company, or its designee, all
my right, title, and interest in and to any and all inventions, original works
of authorship, developments, concepts, improvements or trade secrets, whether or
not patentable or registrable under copyright or similar laws, which I may
solely or jointly conceive or develop or reduce to practice, or cause to be
conceived or developed or reduced to practice, during the period of time I am in
the employ of the Company (collectively referred to as "Inventions") and which
                                                        ----------
(i) are developed using the equipment, supplies, facilities or Confidential
Information of the Company, (ii) result from or are suggested by work performed
by me for the Company, or (iii) relate (or, for employees in Kansas, Minnesota
or Washington only, which directly relate) to the business, or to the actual or
demonstrably anticipated research or development of the Company will be the sole
and exclusive property of the Company, and I will and hereby do assign all my
right, title and interest in such Inventions to the Company, except as provided
in Section 3(f).  I further acknowledge that all original works of authorship
which are made by me (solely or jointly with others) within the scope of and
during the period of my employment with the Company and which are protectible by
copyright are `works made for hire,' as that term is defined in the United
States Copyright Act.

          (b) Patent and Copyright Registrations.  I agree to assist the
              ----------------------------------
Company, or its designee, at the Company's expense, in every proper way to
secure the Company's rights in the Inventions and any copyrights, patents, mask
work rights or other intellectual property rights relating thereto in any and
all countries, including the disclosure to the Company of all pertinent
information and data with respect thereto, the execution of all applications,
specifications, oaths, assignments and all other instruments which the Company
shall deem necessary in order to apply for and obtain such rights and in order
to assign and convey to the Company, its successors,

                                     -2-

<PAGE>

assigns, and nominees the sole and exclusive rights, title and interest in and
to such Inventions, and any copyrights, patents, mask work rights or other
intellectual property rights relating thereto. I further agree that my
obligation to execute or cause to be executed, when it is in my power to do
so, any such instrument or papers shall continue after the termination of this
Agreement. If the Company is unable because of my mental or physical
incapacity or for any other reason to secure my signature to apply for or to
pursue any application for any United States or foreign patents or copyright
registrations covering Inventions or original works of authorship assigned to
the Company as above, then I hereby irrevocably designate and appoint the
Company and its duly authorized officers and agents as my agent and attorney
in fact, to act for and in my behalf and stead to execute and file any such
applications and to do all other lawfully permitted acts to further the
prosecution and issuance of letters patent or copyright registrations thereon
with the same legal force and effect as if executed by me.

          (c) Maintenance of Records.  I agree to keep and maintain adequate and
              ----------------------
current written records of all Inventions made by me (solely or jointly with
others) during the term of my employment with the Company.  The records will be
in the form of notes, sketches, drawings, and any other format that may be
specified by the Company.  The records will be available to and remain the sole
property of the Company at all times.

          (d) Inventions Assigned to the United States.  I agree to assign to
              ----------------------------------------
the United States government all my right, title, and interest in and to any and
all Inventions whenever such full title is required to be in the United States
by a contract between the Company and the United States or any of its agencies.

          (e) Inventions Retained and Licensed.  I provide below a list of all
              --------------------------------
inventions, original works of authorship, developments, improvements, and trade
secrets which were made by me prior to my employment with the Company
(collectively referred to as "Prior Inventions"), which belong to me, which
                              ----------------
relate to the Company's proposed business, products or research and development,
and which are not assigned to the Company hereunder; or, if no such list is
attached, I represent that there are no such Prior Inventions.  If in the course
of my employment with the Company, I incorporate into a Company product, process
or machine a Prior Invention owned by me or in which I have an interest, the
Company is hereby granted and shall have a nonexclusive, royalty-free,
irrevocable, perpetual, worldwide license to make, have made, modify, use and
sell such Prior Invention as part of or in connection with such product, process
or machine.

Prior Inventions:

<PAGE>

          (f) Exception to Assignments.  I understand that the provisions of
              ------------------------
this Agreement requiring assignment of Inventions to the Company do not apply to
any invention that (i) I develop entirely on my own time; and (ii) I develop
without using Company equipment, supplies, facilities, or trade secret
information; and (iii) do not result from any work performed by me for the
Company; and (iv) do not relate (or, for employees in Kansas, Minnesota or
Washington only, do not directly relate) at the time of conception or reduction
                        --------
to practice to the Company's business, or to its actual or demonstrably
anticipated research or development.  Any such invention will be owned entirely
by me, even if developed by me during the time period in which I am employed by
the Company./1/  I will advise the Company promptly in writing of any inventions
that I believe meet the criteria for exclusion set forth herein and are not
otherwise disclosed pursuant to Section 3(e) above.

          (g) Return of Company Documents.  I agree that, at the time of leaving
              ---------------------------
the employ of the Company, I will deliver to the Company (and will not keep in
my possession, recreate or deliver to anyone else) any and all devices, records,
data, notes, reports, proposals, lists, correspondence, specifications, drawings
blueprints, sketches, materials, equipment, other documents or property, or
reproductions of any aforementioned items developed by me pursuant to my
employment with the Company or otherwise belonging to the Company, its
successors or assigns.  In the event of the termination of my employment, I
agree to sign and deliver the `Termination Certificate' attached hereto as
                             -------------------------
Exhibit B.
- ---------

     4.  Notification of New Employer. In the event that I leave the employ of
         ----------------------------
the Company, I hereby grant consent to notification by the Company to my new
employer or consulting client about my rights and obligations under this
Agreement.

     5.  No Solicitation of Employees.  In consideration for my employment by
         ----------------------------
the Company and other valuable consideration, receipt of which is hereby
acknowledged, I agree that during the period of my association with the
Company as an employee, officer and/or director and a period of twelve (12)
months thereafter, I shall not solicit the employment of any person

- -----------------
/1/ For employees in California only, the Company acknowledges the applicability
of Section 2870 of the California Labor Code, which provides:  "Any provision in
an employment agreement which provides that an employee shall assign, or offer
to assign, any of his or her rights in an invention to his or her employer shall
not apply to an invention that the employee developed entirely on his or her own
time without using the employer's equipment, supplies,  facilities, or trade
secret information except for those inventions that either:  (i) relate at the
time of conception or reduction to practice of the invention to the employer's
business, or actual or demonstrably anticipated research or development of the
employer and (ii) result from any work performed by the employee for the
employer.  To the extent a provision in an employment agreement purports to
require an employee to assign an invention otherwise excluded from being
required to be assigned under subdivision (a), the provision is against the
public policy of this state and is unenforceable."

                                     -4-

<PAGE>

who shall then be employed by the Company (as an employee or consultant) or
who shall have been employed by the Company (as an employee or consultant)
within the prior twelve (12) month period, on behalf of myself or any other
person, firm, corporation, association or other entity, directly or
indirectly.

      6.  Representations. I represent that my performance of all the terms of
          ---------------
this Agreement will not breach any agreement to keep in confidence propriety
information acquired by me in confidence or in trust prior to my employment by
the Company. I have not entered into, and I agree I will not enter into, any
oral or written agreement in conflict herewith. I agree to execute any proper
oath or verify any proper document required to carry out the terms of this
Agreement.

      7.  Arbitration and Equitable Relief.
          --------------------------------

          (a) Arbitration.  Except as provided in Section 7(b) below, I agree
              -----------
that any dispute or controversy arising out of or relating to any
interpretation, construction, performance or breach of this Agreement, shall be
settled by arbitration to be held in San Mateo County, California, in accordance
with the rules then in effect of the American Arbitration Association.  The
arbitrator may grant injunctions or other relief in such dispute or controversy.
The decision of the arbitrator shall be final, conclusive and binding on the
parties to the arbitration.  Judgment may be entered on the arbitrator's
decision in any court having jurisdiction.  The Company and I shall each pay
one-half of the costs and expenses of such arbitration, and each of us shall
separately pay our counsel fees and expenses.

          (b) Equitable Remedies.  I agree that it would be impossible or
              ------------------
inadequate to measure and calculate the Company's damages from any breach of the
covenants set forth in Sections 2, 3 and 5 herein.  Accordingly, I agree that if
I breach any such Section, the Company will have available, in addition to any
other right or remedy available, the right to obtain an injunction from a court
of competent jurisdiction restraining such breach or threatened breach and to
specific performance of any such provision of this Agreement.  I further agree
that no bond or other security shall be required in obtaining such equitable
relief and I hereby consent to the issuance of such injunction and to the
ordering of specific performance.

      8.  General Provisions.
          ------------------

          (a) Governing Law; Consent to Personal Jurisdiction.  This Agreement
              -----------------------------------------------
will be governed by the laws of the State of California as they apply to
contracts entered into and wholly to be performed within such State.  I hereby
expressly consent to the nonexclusive personal jurisdiction and venue of the
state and federal courts located in the federal Northern District of California
for any lawsuit filed there against me by the Company arising from or relating
to this Agreement.

          (b) Entire Agreement.  This Agreement sets forth the entire agreement
              ----------------
and understanding between the Company and me relating to the subject matter
herein and merges all prior discussions between us.  No modification of or
amendment to this Agreement, nor any

                                     -5-

<PAGE>

waiver of any rights under this Agreement, will be effective unless in writing
signed by the party to be charged. Any subsequent change or changes in my
duties, salary or compensation will not affect the validity or scope of this
Agreement.

          (b) Severability.  If one or more of the provisions in this Agreement
              ------------
are deemed void by law, then the remaining provisions will continue in full
force and effect.

                                     -6-

<PAGE>

          (c) Successors and Assigns.  This Agreement will be binding upon my
              ----------------------
heirs, executors, administrators and other legal representatives and will be for
the benefit of the Company, its successors, and its assigns.

                       Conflict of Interest Guidelines

     It is the policy of CrossWorlds Software, Inc. and its subsidiaries and
affiliates (together, the "Company") to conduct its affairs in strict compliance
                           -------
with the letter and spirit of the law and to adhere to the highest principles of
business ethics.  Accordingly, all officers, employees and independent
contractors must avoid activities which are in conflict, or give the appearance
of being in conflict, with these principles and with the interests of the
Company.  The following are potentially compromising situations which must be
avoided.  Any exceptions must be reported to the President and written approval
for continuation must be obtained.

     1.  Revealing confidential information to outsiders or misusing
confidential information.  Unauthorized divulging of information is a violation
of this policy whether or not for personal gain and whether or not harm to the
Company is intended.  (The Employment, Confidential Information and Invention
Assignment Agreement elaborates on this principle and is a binding agreement.)

     2.  Accepting or offering substantial gifts, excessive entertainment,
favors or payments which may be deemed to constitute undue influence or
otherwise be improper or embarrassing to the Company.

     3.  Participating in civic or professional organizations that might involve
divulging confidential information of the Company.

     4.  Initiating or approving any form of personal or social harassment of
employees.

     5.  Investing or holding outside directorship in suppliers, customers, or
competing companies, including financial speculations, where such investment or
directorship might influence in any manner a decision or course of action of the
Company.

     6.  Borrowing from or lending to employees, customers or suppliers.

     7.  Acquiring real estate of interest to the Company.

     8.  Improperly using or disclosing to the Company any proprietary
information or trade secrets of any former or concurrent employer or other
person or entity with whom obligations of confidentiality exist.

     9.  Unlawfully discussing prices, costs, customers, sales or markets with
competing companies or their employees.

     10.  Making any unlawful agreement with distributors with respect to
prices.

<PAGE>

     11.  Improperly using or authorizing the use of any inventions which are
the subject of patent claims of any other person or entity.

     12.  Engaging in any conduct which is not in the best interest of the
Company.

     Each officer, employee and independent contractor must take every necessary
action to ensure compliance with these guidelines and to bring problem areas to
the attention of higher management for review.  Violations of this conflict of
interest policy may result in discharge without warning.

provision shall be excluded from this Agreement, (ii) the balance of the
Agreement shall be interpreted as if such provision were so excluded and (iii)

     1.   Deed of Trust.
          -------------

          (a) In consideration of the Loan to Borrowers under the Loan
Agreement, and to secure the Borrowed Amount, Borrowers are delivering herewith
the Third Deed of Trust in form and substance approved by the Company and duly
executed by Borrowers and properly notarized.  The Company may, if the Company
so elects, but without obligation to do so, at any time record the Third Deed of
Trust against Borrowers' principal residence, located at 829 Crescent Avenue,
San Mateo, CA 94401 (the "Principal Residence"), in the official records of the
                          -------------------
county in which the Principal Residence is located.  Within five (5) days after
written demand, Borrowers shall furnish written evidence reasonably satisfactory
to the Company that (i) Borrowers hold good and marketable title to the
Principal Residence; (ii) there is no loan, deed of trust, mortgage or
encumbrance against the Principal Residence other than the first and second
deeds of trust held by Chase Manhattan Bank in the principal amounts of $620,000
and $75,000, respectively, (the "First and Second Deeds of Trust"); and (iii)
Borrowers are not in default under such First and Second Deeds of Trust or
related loan documents.  Upon the sale, conveyance, assignment, alienation,
encumbrance or any other form of transfer of the Principal Residence, the Note
shall be immediately due and payable in full.

                                      -7-
<PAGE>

     2.   Borrowers' Representations, Warranties and Covenants.  To induce the
          ----------------------------------------------------
Company to enter into this Agreement, Borrowers represent, warrant and covenant
to the Company, its successors and assigns, as follows:

          (a) Borrowers will jointly and severally pay the principal sum of the
Note secured hereby, together with interest thereon, and perform all other
obligations required of the Borrowers under the Loan Agreement at the time and
in the manner provided therein.

          (b) Borrowers have good and marketable title to the Principal
Residence free and clear of all security interests, liens, encumbrances and
rights of others other than the First and Second Deeds of Trust constituting
first and second liens against the Principal Residence and the Third Deed of
Trust.  When duly executed, delivered and recorded in the official land records
of the county in which the Principal Residence is located, the Third Deed of
Trust will constitute a valid, perfected security interest in the Principal
Residence, prior to all monetary liens or encumbrances other than the First and
Second Deeds of Trust.

          (c) The consent of no other party or entity is required to grant the
security interest in the Principal Residence (the "Existing Property") as
                                                   -----------------
provided for in this Agreement.  The creation of the security interest
referenced herein, and performance of the obligations of Borrowers hereunder,
will not violate or cause a conflict with any other agreement to which Borrowers
are parties, or to which the Principal Residence is subject.  Borrowers will
perform all obligations of Borrowers in connection with the First and Second
Deeds of Trust (and related documents), and a default thereunder will constitute
a default hereunder.

          (d) Other than the First and Second Deeds of Trust and the Third Deed
of Trust, there are no security interests or liens on the Existing Property that
could be perfected or obtained by filing a financing statement or notice with
any state filing office.

          (e) There are no actions, proceedings, claims or disputes pending or,
to Borrowers' knowledge, threatened against or affecting Borrowers or the
Existing Property except as disclosed to the Company in writing prior to the
date of this Agreement.

          (f) Borrowers shall not sell, convey, assign, alienate, further
encumber or otherwise transfer the Principal Residence, or enter into any
contract or other agreement to sell, convey, assign, alienate, encumber or
otherwise transfer the Principal Residence or any interest therein without the
prior written consent of the Company.

     3.   Default.  Borrowers shall be deemed to be in default of the Note and
          -------
of this Agreement in the event:

          (a) Payment of principal or interest on the Note shall be delinquent
for a period of 10 days or more; or

          (b) Borrowers fail to perform any of the covenants contained in the
Loan Agreement (including exhibits thereto) for a period of 10 days after
written notice thereof from the Company; or

                                      -8-
<PAGE>

          (c) Borrowers' representations and warranties to the Company contained
in this Agreement or the Third Deed of Trust were untrue or incorrect as of the
date of funding of the Loan Agreement; or

          (d) Any default under the First and Second Deeds of Trust.

     4.   Remedies in the Event of Default.  In the case of an event of
          --------------------------------
default, as set forth above, the Company shall have the right to accelerate
payment of the Note upon notice to Borrowers, and shall thereafter be entitled
to pursue any or all of its remedies under applicable law, including, without
limitation, (a) offsetting from Borrowers' salary, bonuses, vacation pay or
other amounts due to Borrowers from the Company, any amount due and payable by
Borrowers under the Note, and/or (b) proceeding against the Principal Residence
under the Third Deed of Trust.

     5.   Insolvency.  Borrowers agree that if a bankruptcy or insolvency
          ----------
proceeding is instituted by or against either Borrower, or if a receiver is
appointed for the property of either Borrower, or if either Borrower makes an
assignment for the benefit of creditors, the entire amount unpaid on the Note
shall become immediately due and payable, and the Company may proceed as
provided in the case of default.

     6.   Miscellaneous.
          -------------

          (a) Successors and Assigns.  The terms and conditions of this
              ----------------------
Agreement shall inure to the benefit of and be binding upon the respective
successors and assigns of the parties.  Nothing in this Agreement, express or
implied, is intended to confer upon any party other than the parties hereto or
their respective successors and assigns any rights, remedies, obligations, or
liabilities under or by reason of this Agreement, except as expressly provided
in this Agreement.

          (b) Governing Law.  This Agreement and all acts and transactions
              -------------
pursuant hereto and the rights and obligations of the parties hereto shall be
governed, construed and interpreted in accordance with the laws of the State of
California, without giving effect to principles of conflicts of law.

          (c) Notices.  Any notice required or permitted by this Agreement shall
              -------
be in writing and shall be deemed sufficient upon receipt, when delivered
personally or by a nationally-recognized delivery service (such as Federal
Express or UPS) or confirmed facsimile, or forty-eight (48) hours after being
deposited in the U.S. mail as certified or registered mail with postage prepaid,
if such notice is addressed to the party to be notified at such party's address
or facsimile number as set forth below, or as subsequently modified by written
notice.

          (d) Severability.  If one or more provisions of this Agreement are
              ------------
held to be unenforceable under applicable law, the parties agree to renegotiate
such provision in good faith.  In the event that the parties cannot reach a
mutually agreeable and enforceable replacement for such provision, then (i) such
provision shall be excluded from this Agreement, (ii) the balance of

                                      -9-
<PAGE>

the Agreement shall be interpreted as if such provision were so excluded and
(iii) the balance of the Agreement shall be enforceable in accordance with its
terms.

          (e) Advice of Legal Counsel.  Each party acknowledges and represents
              -----------------------
that, in executing this Agreement, it has had the opportunity to seek advice as
to its legal rights from legal counsel and that the person signing on its behalf
has read and understood all of the terms and provisions of this Agreement.  This
Agreement shall not be construed against any party by reason of the drafting or
preparation thereof.

                      ADDENDUM TO SECURED PROMISSORY NOTE

     The following shall constitute an Addendum to the Secured Promissory Note
executed by Barton S. Foster and Katherine A. Foster (collectively, "Borrowers")
on November 15, 1999.

                                    RECITALS

     A.  On November 15, 1999, Borrowers executed a Secured Promissory Note in
the amount of $150,000.00 payable to the order of CrossWorlds Software, Inc.
(the "Company"), a copy of which is attached as Exhibit A to this Addendum (the
                                                ---------
"Note").

     B.  On January 27, 2000, the Board of the Directors of the Company approved
the amendment of certain terms of the Note pertaining to forgiveness of
principal and accrued over the course of Barton Foster's continued employment
with the Company.  In connection with this amendment and in accordance with
applicable tax law, the interest rate on the Note shall increase to 5.88%,
compounded annually.  All other provisions of the Note that are not modified by
this Addendum remain in full force and effect.

     NOW, THEREFORE, pursuant to the terms of the Note, and in consideration of
the mutual promises, covenants and conditions hereinafter set forth, the parties
hereto mutually agree as follows:

     1.  Subsection 1 of the Note is hereby amended such that Section 1 now
provides in its entirety as follows:

     "Payment.  Borrowers jointly and severally promise to repay the principal
      -------
and interest balance of this Note within ten days following the earliest to
occur of (A) the sale, conveyance, assignment, alienation or any other form of
transfer of the Borrowers' principal residence located at 829 Crescent Avenue,
San Mateo, CA 94401, (B) the sale, conveyance, assignment, alienation or any
other form of transfer of any shares of the Company's Common Stock purchased by
Borrower pursuant to the exercise of stock options issued by the Company
(excluding transfers to family members or trusts that agree to be bound by the
term of this note and the Loan Agreement), provided however that Borrowers'
repayment obligation under this subsection (B) is limited to the proceeds or
value realized by Borrowers on the sale, conveyance, assignment, alienation or
other form of transfer of the Common Stock, (C) termination of Mr. Foster's
employment with the Company, or (D) November 15, 2001.  So long as Mr. Foster
remains an employee of the Company, the Company shall forgive the principal and
accrued interest of this Note over the course of two (2) years, according to the
following schedule: 1/24 of the principal and accrued interest on the first day
of each month, commencing February 1, 2000.  In the event of a Change of Control
of the Company (as defined below) prior to February 1, 2002, the Company shall
accelerate the forgiveness of the then remaining unpaid balance owing on this
Note so that this Note is forgiven in full as of the effective date of the
transaction.  For purposes of this Note, a Change of Control shall mean a sale
of all or substantially all of the Company's assets, or a merger, consolidation
or other capital reorganization of the Company with or into another corporation,
or any other transaction or series of related transactions in which the

                                       1
<PAGE>

Company's stockholders immediately prior thereto own less than 50% of the voting
stock of the Company (or its successor or parent) immediately thereafter.

     Any payment to be made on a date that is not a business day may be made on
the next business day thereafter.  The records of the Company shall be
conclusive evidence of the unpaid principal balance hereof, and of all payments
made in respect thereof, absent manifest error."

     2.  Entire Agreement.  Section 1 of the Note is modified by the provisions
         ----------------
of this Addendum and the interest rate accruing on the Note is increased to
5.88%, compounded annually.  Except as so modified, the Note shall remain in
full force and effect.  In the event of any conflict between this Addendum and
the Note, this Addendum shall govern.  This Addendum and the Note (together with
the Secured Loan Agreement and Security Agreement executed by Borrowers in
connection with the Note, both of which are part of Exhibit A attached hereto)
                                                    ---------
constitute the entire agreement between Borrowers and the Company regarding the
subject matter hereof.

     IN WITNESS WHEREOF, the parties hereto have caused this Addendum to be duly
executed as of the day and year written below.

     THIS LEASE is made as of the Lease Date set forth in the Basic Lease
Information, by and between the Landlord identified in the Basic Lease
Information ("Landlord"), and the Tenant identified in the Basic Lease
Information ("Tenant"). Landlord and Tenant hereby agree as follows:

1.   PREMISES. Landlord hereby leases to Tenant, and Tenant hereby leases from
Landlord, upon the terms and subject to the conditions of this Lease, the office
space identified in the Basic Lease Information (the "Premises"), in the
Building identified in the Basic Lease Information (the "Building"). The
approximate configuration and location of the Premises is shown on Exhibit A.
                                                                   ---------
Landlord and Tenant agree that the rentable area of the Premises for all
purposes under this Lease shall be the Rentable Area specified in the Basic
Lease Information. The Project identified in the Basic Lease Information (the
"Project") includes the Building, the parking facilities serving the Building
(the "Parking Facility"), and the parcel(s) of Land on which the Building and
the Parking Facility are situated (the "Land"). The Building, the Parking
Facility and the Land are sometimes collectively referred to in this Lease as
the Property.

2.   TERM; POSSESSION. The term of this Lease (the "Term") shall commence on the
Commencement Date as described below and, unless sooner terminated, shall expire
on the Expiration Date set forth in the Basic Lease Information (the "Expiration
Date"). The "Commencement Date" shall be the earlier of (a) February 1, 1997 or
(b) any earlier date upon which Tenant, with Landlord's written permission,
actually occupies and conducts business in any portion of the Premises. The
parties anticipate that the Commencement Date will occur on or about the
Scheduled Commencement Date set forth in the Basic Lease Information (the
"Scheduled Commencement Date"). When the Commencement Date has been established,
Landlord and Tenant shall confirm the Commencement Date and Expiration Date in
writing. As used in this Lease, the first "Lease Year" shall be the period from
(and including) the Commencement Date through (and including) the last day of
the calendar month in which the first anniversary of the Commencement Date
falls, and each period of twelve full consecutive calendar months thereafter
shall be a subsequent Lease Year.

3.   RENT.

     3.1 Base Rent. Tenant agrees to pay to Landlord the Base Rent set forth in
         ---------
the Basic Lease Information, without prior notice or demand, on the first day of
each and every calendar month during the Term, except that Base Rent for the
first full calendar month in which Base Rent is payable shall be paid upon
execution of this Lease and Base Rent for any partial month at the beginning of
the Term shall be paid on the Commencement Date. Base Rent for any partial month
at the beginning or end of the Term shall be prorated based on the actual number
of days in the month.

     3.2 Additional Rent: Increases in Operating Costs and Taxes.
         --------------------------------------------------------

         (a) Definitions.
             ------------

             (1) "Base Operating Costs" means Operating Costs for the calendar
year specified as the Base Year in the Basic Lease Information (excluding
therefrom, however, any Operating Costs of a nature that would not ordinarily be
incurred on an annual, recurring basis).

             (2) "Base Taxes" means Taxes for the calendar year specified as the
Base Year in the Basic Lease Information.

             (3) "Operating Costs" means all costs of managing, operating,
maintaining and repairing the Property, including all costs, expenditures, fees
and charges for: (A) operation, maintenance and repair of the Property
(including maintenance, repair and replacement of glass, the roof coveting or
membrane, and landscaping); (B) utilities and services (including
telecommunications facilities and equipment, recycling programs and trash
removal), and associated supplies and materials; (C) compensation (including
employment taxes and fringe benefits) for persons (below the level of building
manager) who perform duties in connection with the operation, maintenance and
repair of the Building, such compensation to be appropriately allocated for
persons who also perform duties unrelated to the Building; (D) property
(including coverage for earthquake and flood if carded by Landlord), liability,
rental income and other insurance relating to the Property, and expenditures for
deductible amounts paid under such insurance, which shall be charged in the
manner set forth in clause (G) below if the cost incurred is one which would
normally be capitalized; (E) licenses, permits and inspections; (F) complying
with the requirements of any law, statute, ordinance or governmental rule or
regulation or any orders pursuant thereto (collectively "Laws") which shall be
charged in the manner set forth in clause (G) below if the cost incurred is one
which would normally be capitalized; (G) amortization of capital improvements or
repairs which would normally be capitalized under generally accepted accounting
practices required to comply with Laws, or which are intended to reduce
Operating Costs or improve the utility, efficiency or capacity of any Building
System, with interest on the unamortized balance at the rate paid by Landlord on
funds borrowed to finance such capital improvements (or, if Landlord finances
such improvements out of Landlord's funds without borrowing, the rate that
Landlord would have paid to borrow such funds, as reasonably determined by
Landlord), over such useful life as Landlord shall reasonably determine; (H) an
office in the Project for the management of the Property, including expenses of
furnishing and equipping such office and the rental value of any space occupied
for such purposes; (I) property management fees which shall not exceed those
commercially reasonable fees which would be charged by a reputable third party
property manager; (J) accounting, legal and other professional services incurred
in connection with the operation of the Property which benefit the Premises
and/or the common areas and the calculation of Operating Costs and Taxes; (K) a
reasonable allowance for depreciation on machinery and equipment used to
maintain the Property and on other personal property owned by Landlord in the
Property (including window coverings and carpeting in common areas), provided
that such machinery, equipment and/or personal property benefit the Premises
and/or the common areas; (L) contesting the validity or applicability of any
Laws that may affect the Premises and/or the common areas; (M) the Building's
share of any shared or common area maintenance fees and expenses; and (N) any
other expense or charge, whether or not hereinbefore described, which in
accordance with generally

                                       5
<PAGE>

accepted property management practices would be considered an expense of
managing, operating, maintaining and repairing the Property. Operating Costs for
any year (including, without limitation the Base Year) during which average
occupancy of the Building is less than one hundred percent (100%) shall be
calculated based upon the Operating Costs that would have been incurred if the
Building had an average occupancy of one hundred percent (100%) during the
entire calendar year.

     Operating Costs shall not include (i) capital improvements (except as
otherwise provided above); (ii) costs of special services rendered to individual
tenants (including Tenant) for which a special charge is made; (iii) interest
and principal payments on loans or indebtedness secured by the Building; (iv)
costs of improvements for Tenant or other tenants of the Building; (v) costs of
services or other benefits of a type which are not available to Tenant but which
are available to other tenants or occupants, and costs for which Landlord is
reimbursed by other tenants of the Building other than through payment of
tenants' shares of increases in Operating Costs and Taxes; (vi) leasing
commissions, attorneys' fees and other expenses incurred in connection with
leasing space in the Building or enforcing such leases; (vii) depreciation or
amortization, other than as specifically enumerated in the definition of
Operating Costs above; (viii) costs, fines or penalties incurred due to
Landlord's violation of any Law; and (ix) any costs or expenses incurred with
respect to Hazardous Materials, except to the extent the presence of such
Hazardous Materials in, on, under or about the Premises or Property was caused
by Tenant or Tenant's employees, agents, contractors or invitees.

             (4) "Taxes" means: all real property taxes and general, special or
district assessments or other governmental impositions, of whatever kind, nature
or origin, imposed on or by reason of the ownership or use of the Property;
governmental charges, fees or assessments for transit or traffic mitigation
(including area-wide traffic improvement assessments and transportation system
management fees), housing, police, fire or other governmental service or
purported benefits to the Property; personal property taxes assessed on the
personal property of Landlord used in the operation of the Property; service
payments in lieu of taxes and taxes and assessments of every kind and nature
whatsoever levied or assessed in addition to, in lieu of or in substitution for
existing or additional real or personal property taxes on the Property or the
personal property described above; any increases in the foregoing caused by
changes in assessed valuation, tax rate or other factors or circumstances; and
the reasonable cost of contesting by appropriate proceedings the amount or
validity of any taxes, assessments or charges described above. To the extent
paid by Tenant or other tenants as "Tenant's Taxes" (as defined in Section 8 -
Tenant's Taxes), "Tenant's Taxes" shall be excluded from Taxes. The term "Taxes"
shall not include any inheritance taxes or federal or state income taxes of
Landlord.

             (5) "Tenant's Share" means the Rentable Area of the Premises
divided by the total Rentable Area of the Building, as set forth in the Basic
Lease Information. If the Rentable Area of the Building is changed or the
Rentable Area of the Premises is changed by Tenant's leasing of additional space
hereunder or for any other reason, Tenant's Share shall be adjusted accordingly.

                                       6
<PAGE>

         (b) Additional Rent.
             ---------------

             (1) Tenant shall pay Landlord as "Additional Rent" for each
calendar year or portion thereof during the Term Tenant's Share of the sum of
(x) the amount (if any) by which Operating Costs for the period exceed Base
Operating Costs, and (y) the amount (if any) by which Taxes for such period
exceed Base Taxes.

             (2) Prior to the end of the Base Year and each calendar year
thereafter, Landlord shall notify Tenant of Landlord's estimate of Operating
Costs, Taxes and Tenant's Additional Rent for the following calendar year.
Commencing on the first day of January of each calendar year and continuing on
the first day of every month thereafter in such year, Tenant shall pay to
Landlord one-twelfth (1/12th) of the estimated Additional Rent. If Landlord
thereafter estimates that Operating Costs or Taxes for such year will vary from
Landlord's prior estimate, Landlord may, by notice to Tenant, revise the
estimate for such year (and Additional Rent shall thereafter be payable based on
the revised estimate).

             (3) As soon as reasonably practicable after the end of the Base
Year and each calendar year thereafter, Landlord shall furnish Tenant a
statement with respect to such year, showing Operating Costs, Taxes and
Additional Rent for the year, and the total payments made by Tenant with respect
thereto. Unless Tenant raises any objections to Landlord's statement within
ninety (90) days after receipt of the same, such statement shall conclusively be
deemed correct and Tenant shall have no right thereafter to dispute such
statement or any item therein or the computation of Additional Rent based
thereon. If Tenant does object to such statement, Landlord shall provide Tenant
with reasonable verification of the figures shown on the statement and the
parties shall negotiate in good faith to resolve any disputes. Any objection of
Tenant to Landlord's statement and resolution of any dispute shall not postpone
the time for payment of any amounts due Tenant or Landlord based on Landlord's
statement, nor shall any failure of Landlord to deliver Landlord's statement in
a timely manner relieve Tenant of Tenant's obligation to pay any amounts due
Landlord based on Landlord's statement.

             (4) If Tenant's Additional Rent as finally determined for the year
exceeds the total payments made by Tenant on account thereof, Tenant shall pay
Landlord the deficiency within ten (10) days of Tenant's receipt of Landlord's
statement. If the total payments made by Tenant on account thereof exceed
Tenant's Additional Rent as finally determined for the year, Tenant's excess
payment shall be credited toward the rent next due from Tenant under this Lease.
For any partial calendar year at the beginning or end of the Term, Additional
Rent shall be prorated on the basis of a 365-day year by computing Tenant's
Share of the increases in Operating-Costs and Taxes for the entire year and then
prorating such amount for the number of days during such year included in the
Tenn. Notwithstanding the termination of this Lease, Landlord shall pay to
Tenant or Tenant shall pay to Landlord, as the case may be, within ten (10) days
after Tenant's receipt of Landlord's final statement for the calendar year in
which this Lease terminates, the difference between Tenant's Additional Rent for
that year, as finally determined by Landlord, and the total amount previously
paid by Tenant on account thereof.

     If for any reason Base Taxes or Taxes for any year during the Term are
reduced, refunded or otherwise changed, Tenant's Additional Rent shall be
adjusted accordingly. If Taxes are

                                       7
<PAGE>

temporarily reduced as a result of space in the Building being leased to a
tenant that is entitled to an exemption from property taxes or other taxes, then
for purposes of determining Additional Rent for each year in which Taxes are
reduced by any such exemption, Taxes for such year shall be calculated on the
basis of the amount the Taxes for the year would have been in the absence of the
exemption. The obligations of Landlord to refund any overpayment of Additional
Rent and of Tenant to pay any Additional Rent not previously paid shall survive
the expiration of the Term. Notwithstanding anything to the contrary in this
Lease, if there is at any time a decrease in Taxes below the amount of the Taxes
for the Base Year, then for purposes of calculating Additional Rent for the year
in which such decrease occurs and all subsequent periods, Base Taxes shall be
reduced to equal the Taxes for the year in which the decrease occurs.

     3.3 Payment of Rent. All amounts payable or reimbursable by Tenant under
         ---------------
this Lease, including late charges and interest, shall constitute rent and shall
be payable and recoverable as rent in the manner provided in this Lease. All
sums payable to Landlord on demand under the terms of this Lease shall be
payable within ten (10) days after notice from Landlord of the amounts due. All
rent shall be paid without offset, recoupment or deduction in lawful money of
the United States of America to Landlord at Landlord's Address for Payment of
Rent as set forth in the Basic Lease Information, or to such other person or at
such other place as Landlord may from time to time designate.

4.   SECURITY DEPOSIT. On execution of this Lease, Tenant shall deposit with
Landlord the sum set forth in the Basic Lease Information, in cash, as security
for the performance of Tenant's obligations under this Lease. Landlord may (but
shall have no obligation to) use the security deposit or any portion thereof to
cure any Event of Default under this Lease or to compensate Landlord for any
damage Landlord incurs as a result of Tenant's failure to perform any of
Tenant's obligations hereunder. In such event Tenant shall immediately pay to
Landlord an amount sufficient to replenish the security deposit to the sum
initially deposited with Landlord. At the expiration or termination of this
Lease, Landlord shall return to Tenant such portion of the security deposit or
the balance thereof then held by Landlord and not applied as provided above.
Landlord may commingle the security deposit with Landlord's general and other
funds, and Landlord shall not be required to pay interest on the security
deposit to Tenant. The immediately preceding sentence shall not apply to any
amounts drawn down under the Letter of Credit (defined in Paragraph 2 of the

             (b) Tenant's Covenants. No Hazardous Materials shall be Handled by
                 ------------------
Tenant at or about the Premises or Property without Landlord's prior written

             (c) Compliance. Tenant shall at Tenant's expense promptly take all
                 ----------

connection with or as a result of the Handling by Tenant of Hazardous Materials,
and Tenant does not cause the same to be released, by payment, bonding or
otherwise, within ten (10) days after the attachment thereof, Landlord shall
have the right but not the obligation to cause the same to be released and any
sums expended by Landlord in connection therewith shall be payable by Tenant on
demand.

confirm Tenant's compliance with the provisions of this Section, and (ii) to
perform Tenant's obligations under this Section if Tenant has failed to do so
after reasonable notice to Tenant. Landlord shall also have the right to engage
qualified Hazardous Materials consultants to inspect the Premises and review the
Handling by Tenant of Hazardous Materials, including review of all permits,
reports, plans, and other documents regarding same. Tenant shall pay to Landlord
on demand the costs of Landlord's consultants' fees and all costs incurred by
Landlord in performing Tenant's obligations under this Section. Landlord shall
use

                                       10
<PAGE>

reasonable efforts to minimize any interference with Tenant's business caused by
Landlord's entry into the Premises, but Landlord shall not be responsible for
any interference caused thereby.

             (e) Tenant's Indemnification. Tenant agrees to indemnify, defend
                 ------------------------
and hold harmless Landlord and its partners or members and its or their
partners, members, directors, officers, shareholders, employees and agents from
all Environmental Losses and all other claims, actions, losses, damages,
liabilities, costs and expenses of every kind, including reasonable attorneys',
experts' and consultants' fees and costs, incurred at any time and arising from
or in connection with the Handling by Tenant of Hazardous Materials at or about
the Property or Tenant's failure to comply in full with all Environmental
Requirements with respect to the Premises.

6.   ALTERATIONS.

     6.1 Tenant shall not make any alterations, improvements or changes to the
Premises (including installation of any security system or telephone or data
communication wiring), other than the Tenant Improvements ("Alterations"),
without Landlord's prior Written consent (provided, however, that Tenant shall
not be required to obtain Landlord's prior approval for minor, non-structural
Alterations that do not affect any of the Building Systems, are not visible from
the exterior of the Premises, and cost less than Ten Thousand Dollars
($10,000.00), so long as Tenant gives Landlord notice of the proposed
Alterations at least ten (10) days prior to commencement of the Alterations and
complies with all of the following provisions, except that Tenant shall not e
required to obtain Landlord's approval of any plans or specifications therefor).
Any such Alterations shall be completed by Tenant at Tenant's sole cost and
expense: (i) with due diligence, in a good and workmanlike manner, using new
materials; (ii) in compliance with plans and specifications approved (which
approval shall not be unreasonably withheld or delayed) by Landlord; (iii) in
compliance with the construction roles and regulations promulgated by Landlord
from time to time; (iv) in accordance with all applicable Laws (including all
work, whether structural or non-structural, inside or outside the Premises,
required to comply fully with all applicable Laws and necessitated by Tenant's
work); and (v) subject to all conditions which Landlord may in Landlord's
discretion impose. Such conditions may include requirements for Tenant to: (i)
provide payment or performance bonds or additional insurance (from Tenant or
Tenant's contractors, subcontractors or design professionals); (ii) use
contractors or subcontractors designated by Landlord; and (iii) remove all or
part of the Alterations prior to or upon expiration or termination of the Term,
as designated by Landlord. If any work outside the Premises, or any work on or
adjustment to any of the Building Systems, is required in connection with or as
a result of Tenant's work, such work shall be performed at Tenant's expense by
contractors designated by Landlord. Landlord's right to review and approve (or
withhold approval of) Tenant's plans, drawings, specifications, contractor(s)
and other aspects of construction work proposed by Tenant is intended solely to
protect Landlord, the Property and Landlord's interests. No approval or consent
by Landlord shall be deemed or construed to be a representation or warranty by
Landlord as to the adequacy, sufficiency, fitness or suitability thereof or
compliance thereof with applicable Laws or other requirements. Except as
otherwise provided in Landlord's consent, all Alterations shall upon
installation become part of the realty and be the property of Landlord.

                                       11
<PAGE>

     6.2 Before making any Alterations, Tenant shall submit to Landlord for
Landlord's prior approval reasonably detailed final plans and specifications
prepared by a licensed architect or engineer, a copy of the construction
contract, including the name of the contractor and all subcontractors proposed
by Tenant to make the Alterations and a copy of the contractor's license. Tenant
shall reimburse Landlord upon demand for any expenses incurred by Landlord in
connection with any Alterations made by Tenant, including reasonable fees
charged by Landlord's contractors or consultants to review plans and
specifications prepared by Tenant and to update the existing as-built plans and
specifications of the Building to reflect the Alterations. Tenant shall obtain
all applicable permits, authorizations and governmental approvals and deliver
copies of the same to Landlord before commencement of any Alterations.

     6.3 Tenant shall keep the Premises and the Property free and clear of all
liens arising out of any work performed, materials furnished or obligations
incurred by Tenant. If any such lien attaches to the Premises or the Property,
and Tenant does not cause the same to be released by payment, bonding or
otherwise within ten (10) days after the attachment thereof, Landlord shall have
the right but not the obligation to cause the same to be released, and any sums
expended by Landlord in connection therewith shall be payable by Tenant on
demand with interest thereon from the date of expenditure by Landlord at the
Interest Rate (as defined in Section 15.2 - Interest). Tenant shall give
Landlord at least ten (10) days' notice prior to the commencement of any
Alterations and cooperate with Landlord in posting and maintaining notices of
non-responsibility in connection therewith.

     6.4 Subject to the provisions of Section 5 - Use and Compliance with Laws
and the foregoing provisions of this Section, Tenant may install and maintain
furnishings, equipment, movable partitions, business equipment and other trade
fixtures ("Trade Fixtures") in the Premises, provided that the Trade Fixtures do
not become an integral part of the Premises or the Building. Tenant shall
promptly repair any damage to the Premises or the Building caused by any
installation or removal of such Trade Fixtures.

7.   MAINTENANCE AND REPAIRS.

     7.1 By taking possession of the Premises Tenant agrees that the Premises
are then in a good and tenantable condition. During the Term, Tenant at Tenant's
expense but under the direction of Landlord, shall repair and maintain the
Premises, including the interior walls, floor coverings, ceiling (ceiling tiles
and grid), Tenant Improvements, Alterations, fire extinguishers, outlets and
fixtures, and any appliances (including dishwashers, hot water heaters and
garbage disposers) in the Premises, in reasonably good order, and keep the
Premises in a clean, safe and orderly condition.

     7.2 Landlord shall maintain or cause to be maintained in reasonably good
order, condition and repair, the structural portions of the roof, foundations,
floors and exterior walls of the Building, the Building Systems, all structural
parts of the Building and the public and common areas of the Property, such as
elevators, stairs, corridors and restrooms; provided, however, that Tenant shall
pay the cost of repairs for damage occasioned by Tenant's use of the Premises or
the Property or any act or omission of Tenant or Tenant's Representatives or
Visitors. Landlord shall be under no obligation to inspect the Premises. Tenant
shall promptly report in writing to Landlord

                                       12
<PAGE>

any defective condition known to Tenant which Landlord is required to repair. As
a material part of the consideration for this Lease, Tenant hereby waives any
benefits of any applicable existing or future Law, including the provisions of
California Civil Code Sections 1932(1), 1941 and 1942, that allows a tenant to
make repairs at its landlord's expense.

     7.3  Provided that Tenant's rights and benefits are not materially,
adversely affected thereby, Landlord hereby reserves the right, at any time and
from time to time, without liability to Tenant, and without constituting an
eviction, constructive or otherwise, or entitling Tenant to any abatement of
rent or to terminate this Lease or otherwise releasing Tenant from any of
Tenant's obligations under this Lease:

          (a) To make alterations, additions, repairs, improvements to or in or
to decrease the size of area of, all or any part of the Building, the fixtures
and equipment therein, and the Building Systems (provided, however, that
Landlord shall not decrease the size of area of the Premises except to the
extent required to comply with applicable legal requirements or regulations, and
then only to the minimum extent necessary);

          (b) To change the Building's name or street address;

          (c) To install and maintain any and all signs on the exterior and
interior of the Building;

          (d) To reduce, increase, enclose or otherwise change at any time and
from time to time the size, number, location, lay-out and nature of the common
areas and other tenancies and premises in the Property and to create additional
rentable areas through use or enclosure of common areas; and

          (e) If any governmental authority promulgates or revises any Law or
imposes mandatory or voluntary controls or guidelines on Landlord or the
Property relating to the use or conservation of energy or utilities or the
reduction of automobile or other emissions or reduction or management of traffic
or parking on the Property (collectively "Controls"), to comply with such
Controls, whether mandatory or voluntary, or make any alterations to the
Property related thereto.

8.   TENANT'S TAXES. "Tenant's Taxes" shall mean (a) all taxes, assessments,
license fees and other governmental charges or impositions levied or assessed
against or with respect to Tenant's personal property or Trade Fixtures in the
Premises, whether any such imposition is levied directly against Tenant or
levied against Landlord or the Property, (b) all rental, excise, sales or
transaction privilege taxes arising out of this Lease (excluding, however, state
and federal personal or corporate income taxes measured by the income of
Landlord from all sources and excluding inheritance taxes) imposed by any taxing
authority upon Landlord or upon Landlord's receipt of any rent payable by Tenant
pursuant to the terms of this Lease ("Rental Tax"), and (c) any increase in
Taxes attributable to inclusion of a value placed on Tenant's personal property,
Trade Fixtures or Alterations. Tenant shall pay any Rental Tax to Landlord in
addition to and at the same time as Base Rent is payable under this Lease, and
shall pay all other Tenant's Taxes before delinquency (and, at Landlord's
request, shall finish Landlord satisfactory evidence thereof). If Landlord pays
Tenant's Taxes or any portion thereof, Tenant shall reimburse Landlord upon
demand for the

                                       13
<PAGE>

amount of such payment, together with interest at the Interest Rate from the
date of Landlord's payment to the date of Tenant's reimbursement.

9.   UTILITIES AND SERVICES.

     9.1 Description of Services. Landlord shall furnish to the Premises
         -----------------------
reasonable amounts of electricity, water, heat and air-conditioning, and
janitorial service for the uses contemplated hereunder. Landlord shall also
furnish normal fluorescent tube replacement, window washing, elevator service,
and common area toilet room supplies. Landlord shall furnish heat, ventilation
and air-conditioning during the Business Hours specified in the Basic Lease
Information ("Business Hours") on weekdays except public holidays ("Business
Days"). Any additional utilities or services that Landlord may agree to provide
(including lamp or tube replacement for other than Building Standard lighting
fixtures) shall be at Tenant's sole expense.

     9.2 Payment for Additional Utilities and Services.
         ---------------------------------------------

         (a) Upon request by Tenant in accordance with the procedures
established by Landlord from time to time for furnishing HVAC service at times
other than Business Hours on Business Days, Landlord shall furnish such service
to Tenant and Tenant shall pay for such services on an hourly basis at the then
prevailing rate established for the Building by Landlord.

         (b) If the temperature otherwise maintained in any portion of the
Premises by the HVAC systems of the Building is affected as a result of (i) any
lights, machines or equipment used by Tenant in the Premises, or (ii) the
occupancy of the Premises by more than one person per 150 square feet of
rentable area, then Landlord shall, following reasonable notice to Tenant and
thirty (30) days for Tenant to correct the situation, have the right to install
any machinery or equipment reasonably necessary to restore the temperature,
including modifications to the standard air-conditioning equipment. The cost of
any such equipment and modifications, including the cost of installation and any
additional cost of operation and maintenance of the same, shall be paid by
Tenant to Landlord upon demand.

         (c) If Tenant's usage of electricity exceeds the Building's Standard
Electrical Usage as set forth in the Basic Lease Information, Landlord may
determine the amount of such excess use by any reasonable means (including the
installation, following reasonable notice to Tenant and thirty (30) days for
Tenant to correct the situation, at Landlord's request but at Tenant's expense
of a separate meter or other measuring device) and charge Tenant for the cost of
such excess usage. In addition, Landlord may impose a reasonable charge for the
use of any additional or unusual janitorial services required by Tenant because
of any unusual Tenant Improvements or Alterations, the carelessness of Tenant or
the nature of Tenant's business (including hours of operation).

     9.3 Interruption of Services. In the event of an interruption in or failure
         ------------------------
or inability to provide any services or utilities to the Premises or Building
for any reason (a "Service Failure"), such Service Failure shall not, regardless
of its duration, impose upon Landlord any liability whatsoever, constitute an
eviction of Tenant, constructive or otherwise, entitle Tenant to an abatement of
rent or to terminate this Lease or otherwise release Tenant from any of Tenant's

                                       14
<PAGE>

obligations under this Lease. Tenant hereby waives any benefits of any
applicable existing or future Law, including the provisions of California Civil
Code Section 1932(1), permitting the termination of this Lease due to such
interruption, failure or inability.

10.  EXCULPATION AND INDEMNIFICATION.

     10.1 Except to the extent caused by the negligence or breach of this Lease
by Landlord or its employees, agents, contractors or invitees, Landlord shall
not be liable to Tenant for any loss, injury or other damage to any person or
property (including Tenant or Tenant's property) in or about the Premises or the
Property from any cause (including defects in the Property or in any equipment
in the Property; fire, explosion or other casualty; bursting, rapture, leakage
or overflow of any plumbing or other pipes or lines, sprinklers, tanks, drains,
drinking fountains or washstands in, above, or about the Premises or the
Property; or acts of other tenants in the Property). Tenant hereby waives all
claims against Landlord for such damage and the cost and expense of defending
against claims relating to such damage, except that Landlord shall indemnify,
defend and hold Tenant harmless from and against any claims, actions,
liabilities, damages, costs or expenses, including reasonable attorneys' fees
and costs incurred in defending against the same ("Claims") for such damages, to
the extent the same are caused by the willful or negligent acts or omissions of
Landlord or its employees, agents, contractors, invitees or authorized
representatives. In no event, however, shall Landlord be liable to Tenant for
any punitive or consequential damages or damages for loss of business by Tenant.

     10.2 Tenant shall indemnify, defend and hold Landlord harmless from and
against Claims arising from (a) the acts or omissions of Tenant or Tenant's
Representatives or Visitors in or about the Property, or (b) any construction or
other work undertaken by Tenant on the Premises (including any design defects),
or (c) any breach or default under this Lease by Tenant, or (d) any accident,
injury or damage, howsoever and by whomsoever caused, to any person or property,
occurring in or about the Premises during the Term; excepting only such Claims
for any accident, injury or damage to the extent they are caused by the
negligent or willful acts or omissions of Landlord or its employees, agents,
contractors, invitees or authorized representatives.

     10.3 The obligations of the parties under this Section 10 shall survive the
expiration or termination of this Lease.

11.  INSURANCE.

     11.1 Tenant's Insurance.
          ------------------

          (a) Tenant shall maintain in full force throughout the Term,
commercial general liability insurance providing coverage on an occurrence form
basis with limits of not less than Two Million Dollars ($2,000,000.00) each
occurrence for bodily injury and property damage combined, Two Million Dollars
($2,000,000.00) annual general aggregate, and Two Million Dollars
($2,000,000.00) products and completed operations annual aggregate. Tenant's
liability insurance policy or policies shall: (i) include premises and
operations liability coverage, products and completed operations liability
coverage, broad form property damage coverage including completed operations,
blanket contractual liability coverage including, to the maximum extent

                                       15
<PAGE>

possible, coverage for the indemnification obligations of Tenant under this
Lease, and personal and advertising injury coverage; (ii) provide that the
insurance company has the duty to defend all insureds under the policy; (iii)
provide that defense costs are paid in addition to and do not deplete any of the
policy limits; (iv) cover liabilities arising out of or incurred in connection
with Tenant's use or occupancy of the Premises or the Property; and (v) emend
coverage to cover liability for the actions of Tenant's Representatives and
Visitors.

     (b) Tenant shall at all times maintain in effect with respect to any
Alterations and Tenant's Trade Fixtures and personal property, commercial
property insurance providing coverage, at a minimum, for "broad form" perils, to
the extent of 80% of the full replacement cost of covered property. Tenant may
carry such insurance under a blanket policy, provided that such policy provides
equivalent coverage to a separate policy. During the Term, the proceeds from any
such policies of insurance shall be used for the repair or replacement of the
Alterations, Trade Fixtures and personal property so insured. Landlord shall be
provided coverage under such insurance to the extent of its insurable interest
and, if requested by Landlord, both Landlord and Tenant shall sign all documents
reasonably necessary or proper in connection with the settlement of any claim or
loss under such insurance. Landlord will have no obligation to carry insurance
on any Alterations or on Tenant's Trade Fixtures or personal property.

     (c) Each policy of insurance required under this Section shall: (i) be in a
form, and written by an insurer, reasonably acceptable to Landlord, (ii) be
maintained at Tenant's sole cost and expense, and (iii) require at least thirty
(30) days' written notice to Landlord prior to any cancellation, nonrenewal or
modification of insurance coverage. Insurance companies issuing such policies
shall have rating classifications of "A" or better and financial size category
ratings of "VII" or better according to the latest edition of the A.M. Best Key
Rating Guide. All insurance companies issuing such policies shall be licensed to
do business in the state where the Property is located. Any deductible amount
under such insurance shall not exceed $5,000. Tenant shall provide to Landlord,
upon request, evidence that the insurance required to be carried by Tenant
pursuant to this Section, including any endorsement effecting the additional
insured status, is in full force and effect and that premiums therefor have been
paid.

     (d) Tenant shall increase the mounts of insurance as required by any
Mortgagee, and, not more frequently than once every three (3) years, as
recommended by Landlord's insurance broker, if, in the reasonable opinion of
either of them, the amount of insurance then required under this Lease is not
adequate. Any limits set forth in this Lease on the amount or type of coverage
required by Tenant's insurance shall not limit the liability of Tenant under
this Lease.

     (e) Each policy of liability insurance required by this Section shall: (i)
contain a cross liability endorsement or separation of insureds clause; (ii)
provide that any waiver of subrogation rights or release prior to a loss does
not void coverage; (iii) provide that it is primary to and not contributing
with, any policy of insurance carried by Landlord covering the same loss; (iv)
provide that any failure to comply with the reporting provisions shall not
affect coverage provided to Landlord, its partners, property managers and
Mortgagees; and (v) name Landlord, its partners, the Property Manager identified
in the Basic Lease Information (the "Property Manager"), and such other parties
in interest as Landlord may from time to time reasonably designate to Tenant in

                                       16
<PAGE>

writing, as additional insureds. Such additional insureds shall be provided the
same extent of coverage as provided to Tenant under such policies. All
endorsements effecting such additional insured status shall be acceptable to
Landlord and shall be at least as broad as additional insured endorsement form
number CG 20 11 11 85 promulgated by the Insurance Services Office.

          (f) Prior to occupancy of the Premises by Tenant, and not less than
thirty (30) days prior to expiration of any policy thereafter, Tenant shall
furnish to Landlord a certificate of insurance reflecting that the insurance
required by this Section is in force, accompanied by an endorsement showing the
required additional insureds satisfactory to Owner in substance and form.
Notwithstanding the requirements of this paragraph, Tenant shall at Landlord's
request provide to Landlord a certified copy of each insurance policy required
to be in force at any time pursuant to the requirements of this Lease or its
Exhibits.

     11.2 Landlord's Insurance. During the Term, Landlord shall maintain in
          --------------------
effect insurance on the Building against "broad form" perils (to the extent such
coverages are available), with responsible insurers, insuring the Building and
the Tenant Improvements in an amount equal to at least eighty percent (80%) of
the replacement cost thereof, excluding land, foundations, footings and
underground installations. Landlord may, but shall not be obligated to, carry
insurance against additional perils and/or in greater amounts.

     11.3 Waiver of Subrogation. Notwithstanding any provisions to the contrary
          ---------------------
in this Lease, Landlord and Tenant each hereby waive any right of recovery
against the other and the partners, members, shareholders, officers, directors
and authorized representatives of the other for any loss or damage that is
covered by any policy of property insurance maintained by either party (or would
normally be covered by any policy of insurance required by this Lease to be
maintained) with respect to the Premises or the Property or any operation
therein. If any such policy of insurance relating to this Lease or to the
Premises or the Property does not permit the foregoing waiver or if the coverage
under any such policy would be invalidated as a result of such waiver, the party
maintaining such policy shall obtain from the insurer under such policy a waiver
of all right of recovery by way of subrogation against either party in
connection with any claim, loss or damage covered by such policy.

12.  DAMAGE OR DESTRUCTION.

     12.1 Landlord's Duty to Repair.
          -------------------------

          (a) If all or a substantial part of the Premises are rendered
untenantable or inaccessible by damage to all or any part of the Property from
fire or other casualty then, unless either party is entitled to and elects to
terminate this Lease pursuant to Sections 12.2 - Landlord's Right to Terminate
and 12.3 - Tenant's Right to Terminate, Landlord shall, at its expense, use
reasonable efforts to repair and restore the Premises and/or the Property, as
the case may be, to substantially their former condition to the extent permitted
by then applicable Laws; provided, however, that in no event shall Landlord have
any obligation for repair or restoration beyond the extent of insurance proceeds
received by Landlord for such repair or restoration (plus any deductible
amount), or for any of Tenant's personal property, Trade Fixtures or
Alterations.

                                       17
<PAGE>

          (b) If Landlord is required or elects to repair damage to the Premises
and/or the Property, this Lease shall continue in effect. Tenant's Base Rent and
Additional Rent from the date of the casualty through the date of substantial
completion of the repair (or termination of this Lease pursuant to this Article
12) shall be abated with regard to any portion of the Premises that Tenant is
prevented from using by reason of such damage or its repair. In no event shall
Landlord be liable to Tenant by reason of any injury to or interference with
Tenant's business or property arising from fire or other casualty or by reason
of any repairs to any part of the Property necessitated by such casualty.

     12.2 Landlord's Right to Terminate. Landlord may elect to terminate this
          -----------------------------
Lease following damage by fire or other casualty under the following
circumstances:

          (a) If, in the reasonable judgement of Landlord, the Premises and the
Property cannot be substantially repaired and restored under applicable Laws
within one (1) year from the date of the casualty;

          (b) If, in the reasonable judgment of Landlord, adequate proceeds
(with the addition of any deductible amount) are not, for any reason, made
available to Landlord from Landlord's insurance policies (and/or from Landlord's
funds made available for such purpose, at Landlord's sole option) to make the
required repairs;

          (c) If the Building is damaged or destroyed to the extent that, in the
reasonable judgment of Landlord, the cost to repair and restore the Building
would exceed twenty-five percent (25%) of the full replacement cost of the
Building, whether or not the Premises are at all damaged or destroyed; or

          (d) If the fire or other casualty occurs during the last year of the
Term.

If any of the circumstances described in subparagraphs (a), (b), (c) or (d) of
this Section 12.2 occur or arise, Landlord shall notify Tenant in writing of
that fact as soon as reasonably practicable, but in all events within one
hundred and twenty (120) days after the date of the casualty and in such notice
Landlord shall also advise Tenant whether Landlord has elected to terminate this
Lease as provided above.

     12.3 Tenant's Right to Terminate. If all or a substantial part of the
          ---------------------------
Premises are rendered untenantable or inaccessible by damage to all or any part

12, and Tenant may elect to terminate this Lease under the following
circumstances:

ten (10) days after such one hundred and twenty (120)-day period.

                                       18
<PAGE>

          (b) In the circumstance described in Subsection 12.2(a) above; in
which event Tenant may elect to terminate this Lease by giving Landlord notice
of such election to terminate within thirty (30) days after Landlord's notice to
Tenant pursuant to Section 12.2 - Landlord's Right to Terminate.

     12.4 Waiver. Landlord and Tenant each hereby waive the provisions of
          ------
California Civil Code Sections 1932(2), 1933(4) and any other applicable
existing or future Law permitting the termination of a lease agreement in the
event of damage or destruction under any circumstances other than as provided in
Sections 12.2 - Landlord's Right to Terminate and 12.3 - Tenant's Right to
Terminate.

13.  CONDEMNATION.

     13.1 Definitions.
          -----------

          (a) "Award" shall mean all compensation, sums, or anything of value
awarded, paid or received on a total or partial Condemnation.

          (b) "Condemnation" shall mean (i) a permanent taking (or a temporary
taking for a period extending beyond the end of the Term) pursuant to the
exercise of the power of condemnation or eminent domain by any public or
quasi-public authority, private corporation or individual having such power
("Condemnor"), whether by legal proceedings or otherwise, or (ii) a voluntary
sale or transfer by Landlord to any such authority, either under threat of
condemnation or while legal proceedings for condemnation are pending.

          (c) "Date of Condemnation" shall mean the earlier of the date that
title to the property taken is vested in the Condemnor or the date the Condemnor
has the right to possession of the property being condemned.

     13.2 Effect on Lease.
          ---------------

          (a) If the Premises are totally taken by Condemnation, this Lease
shall terminate as of the Date of Condemnation. If a portion but not all of the
Premises is taken by Condemnation, this Lease shall remain in effect; provided,
however, that if the portion of the Premises remaining after the Condemnation
will be unsuitable for Tenant's continued use, then upon notice to Landlord
within thirty (30) days after Landlord notifies Tenant of the Condemnation,
Tenant may terminate this Lease effective as of the Date of Condemnation.

          (b) If twenty-five percent (25%) or more of the Land or of the Parking
Facility or of the floor area in the Building is taken by Condemnation, or if as
a result of any Condemnation the Building is no longer reasonably suitable for
use as an office building, whether or not any portion of the Premises is taken,
Landlord may elect to terminate this Lease, effective as of the Date of
Condemnation, by notice to Tenant within thirty (30) days after the Date of
Condemnation.

Condemnor for a period not extending beyond the end of the Term, this Lease
shall remain in full force and effect.

                                       19
<PAGE>

     13.3 Restoration. If this Lease is not terminated as provided in Section
          -----------
13.2 - Effect on Lease, Landlord, at its expense, shall diligently proceed to
repair and restore the Premises to substantially its former condition (to the
extent permitted by then applicable Laws) and/or repair and restore the Building
to an architecturally complete office building; provided, however, that
Landlord's obligations to so repair and restore shall be limited to the amount
of any Award received by Landlord and not required to be paid to any Mortgagee
(as defined in Section 20.2 below). In no event shall Landlord have any
obligation to repair or replace any improvements in the Premises beyond the
amount of any Award received by Landlord for such repair or to repair or replace
any of Tenant's personal property, Trade Fixtures, or Alterations.

     13.4 Abatement and Reduction of Rent. If any portion of the Premises is
          -------------------------------
taken in a Condemnation or is rendered permanently untenantable by repairs
necessitated by the Condemnation, and this Lease is not terminated, the Base
Rent and Additional Rent payable under this Lease shall be proportionally
reduced as of the Date of Condemnation based upon the percentage of rentable
square feet in the Premises so taken or rendered permanently untenantable. In
addition, if this Lease remains in effect following a Condemnation and Landlord
proceeds to repair and restore the Premises, the Base Rent and Additional Rent
payable under this Lease shall be abated during the period of such repair or
restoration to the extent such repairs prevent Tenant's use of the Premises.

     13.5 Awards. Any Award made shall be paid to Landlord, and Tenant hereby
          ------
assigns to Landlord, and waives all interest in or claim to, any such Award,
including any claim for the value of the unexpired Term; provided, however, that
Tenant shall be entitled to receive, or to prosecute a separate claim for, an
Award for a temporary taking of the Premises or a portion thereof by a Condemnor
where this Lease is not terminated (to the extent such Award relates to the
unexpired Term), or an Award or portion thereof separately designated for
relocation expenses or the interruption of or damage to Tenant's business or as
compensation for Tenant's personal property, Trade Fixtures or Alterations.

     13.6 Waiver. Landlord and Tenant each hereby waive the provisions of
          ------
California Code of Civil Procedure Section 1265.130 and any other applicable
existing or future Law allowing either party to petition for a termination of
this Lease upon a partial taking of the Premises and/or the Property.

14.  ASSIGNMENT AND SUBLETTING.

     14.1 Landlord's Consent Required. Tenant shall not assign, mortgage,
          ---------------------------
pledge, hypothecate or encumber this Lease or any interest therein, or sublet or
license or permit the use or occupancy of the Premises or any part thereof by or
for the benefit of anyone other than Tenant, or in any other manner transfer all
or any part of Tenant's interests under this Lease (each and all a "Transfer"),
without the prior written consent of Landlord (except as provided in Section
14.9 below), which (subject to the other provisions of this Section 14) shall
not be unreasonably withheld. If Tenant is a business entity, any direct or
indirect transfer of fifty percent (50%) or more of the ownership interest of
the entity (whether in a single transaction or in the aggregate through more
than one transaction) shall be deemed a Transfer. Notwithstanding any provision
in

                                       20
<PAGE>

this Lease to the contrary, Tenant shall not mortgage, pledge, hypothecate or
otherwise encumber all or any portion of Tenant's interest under this Lease.

     14.2 Reasonable Consent.
          ------------------

          (a) If Tenant complies with the following conditions, Landlord shall
not unreasonably withhold or delay its consent to the subletting of the Premises
or any portion thereof or the assignment of this Lease. Prior to any proposed
Transfer, Tenant shall submit in writing to Landlord (i) the name and legal
composition of the proposed assignee, subtenant, user or other transferee (each
a "Transferee"); (ii) the nature of the business proposed to be carried on in
the Premises; (iii) a current balance sheet, income statements for the last two
years and such other reasonable financial and other information concerning the
proposed Transferee as Landlord may request; and (iv) a copy of the proposed
assignment, sublease or other agreement governing the proposed Transfer. Within
fifteen (15) Business Days after Landlord receives all such information it shall
notify Tenant whether it approves or disapproves such Transfer or if it elects
to proceed under Section 14.7 - Landlord's Right to Space.

          (b) The parties hereto agree and acknowledge that, among other
circumstances for which Landlord could reasonably withhold consent to a proposed
Transfer, it shall be reasonable for Landlord to withhold consent where (i) the
proposed Transferee does not intend itself to occupy the entire portion of the
Premises assigned or sublet, (ii) Landlord reasonably disapproves of the
Transferee's business operating ability or history, reputation or
creditworthiness or the character of the business to be conducted by the
Transferee at the Premises, (iii) the Transferee is a governmental agency or
unit or an existing tenant in the Project, (iv) the proposed Transfer would
violate any "exclusive" rights of any tenants in the Project, (v) the rental and
other consideration payable by the Transferee is less than that currently being
paid by tenants under new leases of comparable space in the Building, or (vi)
Landlord otherwise determines that the proposed Transfer would have the effect
of decreasing the value of the Building or increasing the expenses associated
with operating, maintaining and repairing the Property. In no event may Tenant
publicly offer or advertise all or any portion of the Premises for assignment or
sublease at a rental less than that then sought by Landlord for a direct lease
(non-sublease) of comparable space in the Project.

     14.3 Excess Consideration. If Landlord consents to the Transfer, Tenant
          --------------------
shall pay to Landlord as additional rent, within ten (10) days after receipt by
Tenant, seventy-five percent (75%) of any consideration paid by the Transferee
for the Transfer, including, in the case of a sublease, the excess of the rent
and other consideration paid the subtenant over the amount of Base Rent and
Additional Rent payable hereunder applicable to the subleased space.

     14.4 No Release Of Tenant. No consent by Landlord to any Transfer shall
          --------------------
relieve Tenant of any obligation to be performed by Tenant under this Lease,
whether occurring before or after such consent, assignment, subletting or other
Transfer. Each Transferee shall be jointly and severally liable with Tenant (and
Tenant shall be jointly and severally liable with each Transferee) for the
payment of rent (or, in the case of a sublease, rent in the amount set forth in
the sublease) and for the performance of all other terms and provisions of this
Lease. The consent by Landlord to any Transfer shall not relieve Tenant or any
such Transferee from the obligation to obtain Landlord's express prior written
consent to any subsequent Transfer by Tenant or any Transferee.

                                       21
<PAGE>

The acceptance of rent by Landlord from any other person shall not be deemed to
be a waiver by Landlord of any provision of this Lease or to be a consent to any
Transfer.

     14.5 Expenses and Attorneys' Fees. Tenant shall pay to Landlord on demand
          ----------------------------
all costs and expenses (including reasonable attorneys' fees) incurred by
Landlord in connection with reviewing or consenting to any proposed Transfer
(including any request for consent to, or any waiver of Landlord's rights in
connection with, any security interest in any of Tenant's property at the
Premises).

     14.6 Effectiveness of Transfer. Prior to the date on which any permitted
          -------------------------
Transfer (whether or not requiting Landlord's consent) becomes effective, Tenant
shall deliver to Landlord a counterpart of the fully executed Transfer document
and Landlord's standard form of Consent to Assignment or Consent to Sublease
executed by Tenant and the Transferee in which each of Tenant and the Transferee
confirms its obligations pursuant to this Lease. Failure or refusal of a
Transferee to execute any such instrument shall not release or discharge the
Transferee from liability as provided herein. The voluntary, involuntary or
other surrender of this Lease by Tenant, or a mutual cancellation by Landlord
and Tenant, shall not work a merger, and any such surrender or cancellation
shall, at the option of Landlord, either terminate all or any existing subleases
or operate as an assignment to Landlord of any or all of such subleases.

     14.7 Landlord's Right to Space. Notwithstanding any of the above provisions
          -------------------------
of this Section to the contrary, if Tenant notifies Landlord that it desires to
enter into a Transfer, Landlord, in lieu of consenting to such Transfer, may
elect (x) in the case of an assignment or a sublease of the entire Premises, to
terminate this Lease in its entirety, or (y) in the case of a sublease of less
than the entire Premises for a term substantially equal to the remaining Term of
this Lease, to terminate this Lease as it relates to the space proposed to be
subleased by Tenant. In such event, this Lease will terminate (or the space
proposed to be subleased will be removed from the Premises subject to this Lease
and the Base Rent and Tenant's Share under this Lease shall be proportionately
reduced) on the date the Transfer was proposed to be effective, and Landlord may
lease such space to any party, including the prospective Transferee identified
by Tenant.

     14.8 Assignment of Sublease Rents. Tenant hereby absolutely and irrevocably
          ----------------------------
assigns to Landlord any and all rights to receive rent and other consideration
from any sublease and agrees that Landlord, as assignee or as attorney-in-fact
for Tenant for purposes hereof, or a receiver for Tenant appointed on Landlord's
application may (but shall not be obligated to) collect such rents and other
consideration and apply the same toward Tenant's obligations to Landlord under
this Lease; provided, however, that Landlord grants to Tenant at all times prior
to occurrence of any breach or default by Tenant a revocable license to collect
such rents (which license shall automatically and without notice be and be
deemed to have been revoked and terminated immediately upon any Event of
Default).

     14.9 Transfer to Affiliate. Tenant may assign this Lease or sublet the
          ---------------------
Premises or any portion thereof, without Landlord's consent, to any corporation
or other entity that controls, is controlled by, or is under common control with
Tenant, or to any corporation or other entity resulting from a merger or
consolidation with Tenant, or to any person or entity that acquires

                                       22
<PAGE>

substantially all the assets of Tenant as a going concern (collectively, an
"Affiliate"), provided that the Affiliate assumes in writing all of Tenant's
obligations under this Lease.

15.  DEFAULT AND REMEDIES.

     15.1 Events of Default. The occurrence of any of the following shall
          -----------------
constitute an "Event of Default" by Tenant:

          (a) Tenant fails to make any payment of rent when due, or any amount
required to replenish the security deposit as provided in Section 4 above, if
payment in full is not received by Landlord within three (3) business days after
written notice that it is due.

          (b) Tenant abandons the Premises and fails to pay rent.

          (c) Tenant fails to deliver any estoppel certificate requested by
Landlord within the period described in subsection 21.1 below.

          (d) Tenant violates the restrictions on Transfer set forth in Section
14 -Assignment and Subletting.

          (e) Tenant ceases doing business as a going concern; makes an
assignment for the benefit of creditors; is adjudicated an insolvent, files a
petition (or files an answer admitting the material allegations of a petition)
seeking relief under any under any state or federal bankruptcy or other statute,
law or regulation affecting creditors' rights; all or substantially all of
Tenant's assets are subject to judicial seizure or attachment and are not
released within 30 days, or Tenant consents to or acquiesces in the appointment
of a trustee, receiver or liquidator for Tenant or for all or any substantial
part of Tenant's assets.

          (f) Tenant fails, within ninety (90) days after the commencement of
any proceedings against Tenant seeking relief under any state or federal
bankruptcy or other statute, law or regulation affecting creditors' rights, to
have such proceedings dismissed, or Tenant fails, within ninety (90) days after
an appointment, without Tenant's consent or acquiescence, of any trustee,
receiver or liquidator for Tenant or for all or any substantial part of Tenant's
assets, to have such appointment vacated.

          (g) Tenant fails to perform or comply with any provision of this Lease
other than those described in (a) through (f) above, and does not fully cure
such failure within fifteen (15) days after notice to Tenant or, if such failure
cannot be cured within such fifteen (15)-day period, Tenant fails within such
fifteen (15)-day period to commence, and thereafter diligently proceed with, all
actions necessary to cure such failure as soon as reasonably possible but in all
events within ninety (90) days after such notice; provided, however, that if
Landlord in Landlord's reasonable judgment determines that such failure cannot
or will not be cured by Tenant within such ninety (90) days, then such failure
shall constitute an Event of Default immediately upon such notice to Tenant.

                                       23
<PAGE>

     15.2 Remedies. Upon the occurrence of an Event of Default, Landlord shall
          --------
have the following remedies, which shall not be exclusive but shall be
cumulative and shall be in addition to any other remedies now or hereafter
allowed by law:

          (a) Landlord may terminate Tenant's right to possession of the
Premises at any time by written notice to Tenant, and such termination of
Tenant's right to possession shall terminate the Lease. Tenant expressly
acknowledges that in the absence of such written notice from Landlord, no other
act of Landlord, including re-entry into the Premises, efforts to relet the
Premises, reletting of the Premises for Tenant's account, storage of Tenant's
personal property and Trade Fixtures, acceptance of keys to the Premises from
Tenant or exercise of any other rights and remedies under this Section, shall
constitute an acceptance of Tenant's surrender of the Premises or constitute a
termination of this Lease or of Tenant's right to possession of the Premises.
Upon such termination in writing of Tenant's right to possession of the
Premises, as herein provided, this Lease shall terminate and Landlord shall be
entitled to recover damages from Tenant as provided in California Civil Code
Section 1951.2 and any other applicable existing or future Law providing for
recovery of damages for such breach, including the worth at the time of award of
the amount by which the rent which would be payable by Tenant hereunder for the
remainder of the Term after the date of the award of damages, including
Additional Rent as reasonably estimated by Landlord, exceeds the amount of such
rental loss as Tenant proves could have been reasonably avoided, discounted at
the discount rate published by the Federal Reserve Bank of San Francisco for
member banks at the time of the award plus one percent (1%).

          (b) Landlord shall have the remedy described in California Civil Code
Section 1951.4 so long as Landlord does not terminate Tenant's right to
possession.. (Landlord may continue this Lease in effect after Tenant's breach
and abandonment and recover rent as it becomes due, if Tenant has the right to
sublet or assign, subject only to reasonable limitations).

          (c) Landlord may cure the Event of Default at Tenant's expense. If
Landlord pays any sum or incurs any expense in curing the Event of Default,
Tenant shall reimburse Landlord upon demand for the amount of such payment or
expense with interest at the Interest Rate from the date the sum is paid or the
expense is incurred until Landlord is reimbursed by Tenant.

          (d) Landlord may remove all Tenant's property from the Premises, and
such property may be stored by Landlord in a public warehouse or elsewhere at
the sole cost and for the account of Tenant. If Landlord does not elect to store
any or all of Tenant's property left in the Premises, Landlord may consider such
property to be abandoned by Tenant, and Landlord may thereupon dispose of such
property in any manner deemed appropriate by Landlord. Any proceeds realized by
Landlord on the disposal of any such property shall be applied first to offset
all expenses of storage and sale, then credited against Tenant's outstanding
obligations to Landlord under this Lease, and any balance remaining after
satisfaction of all obligations of Tenant under this Lease shall be delivered to
Tenant.

16.  LATE CHARGE AND INTEREST.

     16.1 Late Charge. If any payment of rent is not received by Landlord when
          -----------
due, Tenant shall pay to Landlord on demand as a late charge an additional
amount equal to four percent (4%)

                                       24
<PAGE>

of the overdue payment. A late charge shall not be imposed more than once on any
particular installment not paid when due, but imposition of a late charge on any
payment not made when due does not eliminate or supersede late charges imposed
on other (prior) payments not made when due or preclude imposition of a late
charge on other installments or payments not made when due.

     16.2 Interest. In addition to the late charges referred to above, which are
          --------
intended to defray Landlord's costs resulting from late payments, any payment
from Tenant to Landlord not paid when due shall at Landlord's option bear
interest from the date due until paid to Landlord by Tenant at the rate of
fifteen percent (15%) per annum or the maximum lawful rate that Landlord may
charge to Tenant under applicable laws, whichever is less (the "Interest Rate").
Acceptance of any late charge and/or interest shall not constitute a waiver of
Tenant's default with respect to the overdue sum or prevent Landlord from
exercising any of its other rights and remedies under this Lease.

17.  WAIVER. No provisions of this Lease shall be deemed waived by either party
unless such waiver is in a writing signed by the waiving party. The waiver by
either party of any breach of any provision of this Lease shall not be deemed a
waiver of such provision or of any subsequent breach of the same or any other
provision of this Lease. No delay or omission in the exercise of any right or
remedy of one party upon any default by the other party shall impair such right
or remedy or be construed as a waiver. Landlord's acceptance of any payments of
rent due under this Lease shall not be deemed a waiver of any default by Tenant
under this Lease (including Tenant's recurrent failure to timely pay rent) other
than Tenant's nonpayment of the accepted sums, and no endorsement or statement
on any check or accompanying any check or payment shall be deemed an accord and
satisfaction. The consent to or approval of any act requiring consent or
approval of the other party shall not be deemed to waive or render unnecessary
consent to or approval of any subsequent act requiting consent.

18.  ENTRY, INSPECTION AND CLOSURE. Upon reasonable oral or written notice to
Tenant (and without notice in emergencies), Landlord and its authorized
representatives may enter the Premises at all reasonable times to determine
whether the Premises are in good condition, to determine whether Tenant is
complying with its obligations under this Lease, to perform any maintenance or
repair of the Premises or the Building that Landlord has the right or obligation
to perform, to install or repair improvements for other tenants where access to
the Premises is required for such installation or repair, to serve, post or keep
posted any notices required or allowed under the provisions of this Lease, to
show the Premises to prospective brokers, agents, buyers, transferees,
Mortgagees or tenants, or to do any other act or thing necessary for the safety
or preservation of the Premises or the Building. When reasonably necessary
Landlord may temporarily close entrances, doors, corridors, elevators or other
facilities in the Building without liability to Tenant by reason of such
closure. Landlord shall conduct its activities under this Section in a manner
that will minimize inconvenience to Tenant without incurring additional expense
to Landlord. In no event shall Tenant be entitled to an abatement of rent on
account of any entry by Landlord, and Landlord shall not be liable in any manner
for any inconvenience, loss of business or other damage to Tenant or other
persons arising out of Landlord's entry on the Premises in accordance with this
Section. No action by Landlord pursuant to this paragraph shall constitute an
eviction of Tenant, constructive or otherwise, entitle Tenant to an abatement of
rent or to terminate this Lease or otherwise release Tenant from any of Tenant's
obligations under this Lease.

                                       25
<PAGE>

19.  SURRENDER AND HOLDING OVER.

     19.1 Surrender. Upon the expiration or termination of this Lease, Tenant
          ---------
shall surrender the Premises and all Tenant Improvements and Alterations to
Landlord broom-clean and in their original condition, except for reasonable wear
and tear, damage from casualty or condemnation and any changes resulting from
approved Alterations; provided, however, that prior to the expiration or
termination of this Lease Tenant shall remove all telephone and other cabling
installed in the Building by Tenant and remove from the Premises all Tenant's
personal property, Trade Fixtures and Alterations that Tenant has the right or
is required by Landlord to remove under the provisions of this Lease, and repair
any damage caused by such removal. If such removal is not completed before the
expiration or termination of the Term, Landlord shall have the right (but no
obligation) to remove the same, and Tenant shall pay Landlord on demand for all
costs of removal and storage thereof and for the rental value of the Premises
for the period from the end of the Term through the end of the time reasonably
required for such removal. Landlord shall also have the right to retain or
dispose of all or any portion of such property if Tenant does not pay all such
costs and retrieve the property within ten (10) days after receipt of notice
from Landlord (in which event title to all such property described in Landlord's
notice shall be transferred to and vest in Landlord). Tenant waives all Claims
against Landlord for any damage or loss to Tenant resulting from Landlord's
removal, storage, retention, or disposition of any such property. Upon
expiration or termination of this Lease or of Tenant's possession, whichever is
earliest, Tenant shall surrender all keys to the Premises or any other part of
the Building and shall deliver to Landlord all keys for or make known to
Landlord the combination of locks on all safes, cabinets and vaults that may be
located in the Premises. Tenant's obligations under this Section shall survive
the expiration or termination of this Lease.

     19.2 Holding Over. If Tenant (directly or through any Transferee or other
          ------------
successor-in-interest of Tenant) remains in possession of the Premises after the
expiration or termination of this Lease, Tenant's continued possession shall be
on the basis of a tenancy at the sufferance of Landlord. In such event, Tenant
shall continue to comply with or perform all the terms and obligations of Tenant
under this Lease, except that the monthly Base Rent during Tenant's holding over
shall be twice the Base Rent payable in the last full month prior to the
termination hereof. Acceptance by Landlord of rent after such termination shall
not constitute a renewal of this Lease; and nothing contained in this provision
shall be deemed to waive Landlord's right of re-entry or any other right
hereunder or at law. Tenant shall indemnify, defend and hold Landlord harmless
from and against all Claims arising or resulting directly or indirectly from
Tenant's failure to timely surrender the Premises, including (i) any rent
payable by or any loss, cost, or damages claimed by any prospective tenant of
the Premises, and (ii) Landlord's damages as a result of such prospective-tenant
rescinding or refusing to enter into the prospective lease of the Premises by
reason of such failure to timely surrender the Premises.

20.  ENCUMBRANCES.

     20.1 Subordination. This Lease is expressly made subject and subordinate to
          -------------
any mortgage, deed of trust, ground lease, underlying lease or like encumbrance
affecting any part of the Property or any interest of Landlord therein which is
now existing or hereafter executed or recorded ("Encumbrance"); provided,
however, that such subordination shall only be effective, as

                                       26
<PAGE>

to future Encumbrances, if the holder of the Encumbrance agrees that this Lease
shall survive the termination of the Encumbrance by lapse of time, foreclosure
or otherwise so long as Tenant is not in default under this Lease. Provided the
conditions of the preceding sentence are satisfied, Tenant shall execute and
deliver to Landlord, within ten (10) days after written request therefor by
Landlord and in a form reasonably requested by Landlord, any additional
documents evidencing the subordination of this Lease with respect to any such
Encumbrance and the nondisturbance agreement of the holder of any such
Encumbrance. If the interest of Landlord in the Property is transferred pursuant
to or in lieu of proceedings for enforcement of any Encumbrance, Tenant shall
immediately and automatically attorn to the new owner, and this Lease shall
continue in full force and effect as a direct lease between the Purchaser and
Tenant on the terms and conditions set forth in this Lease. Landlord agrees to
use reasonable efforts to obtain, at Tenant's sole cost and expense, a
non-disturbance agreement from the holder of any existing Encumbrance under
which the holder of the Encumbrance shall agree that this lease shall survive
the termination of the "Encumbrance by lapse of time, foreclosure, or otherwise
so long as Tenant is not in default under this lease beyond any applicable cure
period.

     20.2 Mortgagee Protection. Tenant agrees to give any holder of any
          --------------------
Encumbrance covering any part of the Property ("Mortgagee"), by registered mail,
a copy of any notice of default served upon Landlord, provided that prior to
such notice Tenant has been notified in writing (by way of notice of assignment
of rents and leases, or otherwise) of the address of such Mortgagee. If Landlord
shall have failed to cure such default within thirty (30) days from the
effective date of such notice of default, then the Mortgagee shall have an
additional thirty (30) days within which to cure such default or if such default
cannot be cured within that time, then such additional time as may be necessary
to cure such default (including the time necessary to foreclose or otherwise
terminate its Encumbrance, if necessary to effect such cure), and this Lease
shall not be terminated so long as such remedies are being diligently pursued.

21.  ESTOPPEL CERTIFICATES AND FINANCIAL STATEMENTS.

     21.1 Estoppel Certificates. Within twenty (20) days after written request
          ---------------------
therefor, Tenant shall execute and deliver to Landlord, in a form provided by or
reasonably satisfactory to Landlord, a certificate stating, to the extent tree,
that this Lease is in full force and effect, describing any amendments or
modifications hereto, acknowledging that this Lease is subordinate or prior, as
the case may be, to any Encumbrance and stating any other information Landlord
may reasonably request, including the Term, the monthly Base Rent, the date to
which Rent has been paid, the amount of any security deposit or prepaid rent,
whether either party hereto is in default under the terms of the Lease, and
whether Landlord has completed its construction obligations hereunder (if-any).
Any person or entity purchasing, acquiring an interest in or extending financing
with respect to the Property shall be entitled to rely upon any such
certificate. If Tenant fails to deliver such certificate within twenty (20) days
after Landlord's second written request therefor, Tenant shall be liable to
Landlord for any damages incurred by Landlord including any profits or other
benefits from any financing of the Property or any interest therein which are
lost or made unavailable as a result, directly or indirectly, of Tenant's
failure or refusal to timely execute or deliver such estoppel certificate.

                                       27
<PAGE>

     21.2 Financial Statements. Upon request by Landlord, not more than once a
          --------------------
year, Tenant shall deliver to Landlord a copy of Tenant's financial statements
(including at least a year end balance sheet and a statement of profit and loss)
for each of the three most recently completed years, prepared in accordance with
generally accepted accounting principles (and, if such is Tenant's normal
practice, audited by an independent certified public accountant), all then
available subsequent interim statements, and such other financial information as
may reasonably be requested by Landlord or required by any Mortgagee.

22.  NOTICES. Any notice, demand, request, consent or approval that either party
desires or is required to give to the other party under this Lease shall be in
writing and shall be served personally, delivered by messenger or courier
service, or sent by U.S. certified mail, return receipt requested, postage
prepaid, addressed to the other party at the party's address for notices set
forth in the Basic Lease Information. Notices delivered personally will be
effective immediately upon receipt (or refusal of delivery or receipt); notices
sent by independent messenger or courier service will be effective one (1) day
after acceptance by the independent service for delivery; notices sent by mail
in accordance with this Section will be effective upon the date certified by the
U.S. Post Office for delivery or refusal to accept delivery. Either party may
change its address for notices hereunder by a notice to the other party
complying with this Section. If Tenant sublets the Premises, notices from
Landlord shall be effective on the subtenant when given to Tenant pursuant to
this Section.

23.  ATTORNEYS' FEES.

     23.1 Disputes between Landlord and Tenant. In the event of any litigation
          ------------------------------------
or arbitration regarding any rights and obligations under this Lease, the
prevailing party shall be entitled to recover reasonable attorneys' fees and
court costs in addition to any other relief which may be granted. The
"prevailing party" shall mean the party receiving substantially the relief
desired, whether by settlement, dismissal, summary judgment, judgment, or
otherwise.

     23.2 Other Litigation. If Landlord, without fault on Landlord's part, is
          ----------------
made a party to any litigation instituted by Tenant or by any third party
against Tenant, or by or against any Transferee or other occupant of the
Premises or otherwise arising out of or resulting from any act or transaction of
Tenant or of any such Transferee or occupant, Tenant shall hold Landlord
harmless from any judgment rendered against Landlord or the Premises or any part
thereof, and reimburse Landlord upon demand for all costs and expenses,
including reasonable attorneys' fees, incurred by Landlord in or in connection
with such litigation.

24.  QUIET POSSESSION. Subject to Tenant's full and timely performance of all of
Tenant's obligations under this Lease and subject to the terms of this Lease,
including Section 20 -Encumbrances, Tenant shall have the quiet possession of
the Premises throughout the Term as against any persons or entities lawfully
claiming by, through or under Landlord.

25.  SECURITY MEASURES. Landlord may, but shall be under no obligation to,
implement security measures for the Property, such as the registration or search
of all persons entering or leaving the Building, requiting identification for
access to the Building, evacuation of the Building for cause, suspected cause,
or for drill purposes, the issuance of magnetic pass cards or keys for

                                       28
<PAGE>

Building or elevator access and other actions that Landlord deems necessary or
appropriate to prevent any threat of property loss or damage, bodily injury or
business interruption; provided, however, that such measures shall be
implemented in a way as not to inconvenience tenants of the Building
unreasonably. Landlord shall at all times have the right to change, alter or
reduce any such security services or measures. Tenant shall cooperate and comply
with, and cause Tenant's Representatives and Visitors to cooperate and comply
with, such security measures. Landlord, its agents and employees shall have no
liability to Tenant or its Representatives or Visitors for the implementation or
exercise of, or the failure to implement or exercise, any such security measures
or for any resulting disturbance of Tenant's use or enjoyment of the Premises.

26.  FORCE MAJEURE. If Landlord is delayed, interrupted or prevented from
performing any of its obligations under this Lease, including its obligations
under the Construction Rider (if any), and such delay, interruption or
prevention is due to fire, act of God, governmental act or failure to act, labor
dispute, unavailability of materials or any cause outside the reasonable control
of Landlord, then the time for performance of the affected obligations of
Landlord shall be extended for a period equivalent to the period of such delay,
interruption or prevention.

27.  RULES AND REGULATIONS. Tenant shall be bound by and shall comply with the
roles and regulations attached to and made a part of this Lease as Exhibit C to
                                                                   ---------
the extent those roles and regulations are not in conflict with the terms of
this Lease, as well as any reasonable roles and regulations hereafter adopted by
Landlord for all tenants of the Building, upon notice to Tenant thereof
(collectively, the "Building Rules"). Landlord shall not be responsible to
Tenant or to any other person for any violation of, or failure to observe, the
Building Rules by any other tenant or other person.

28.  LANDLORD'S LIABILITY. The term "Landlord," as used in this Lease, shall
mean only the owner or owners of the Building at the time in question. In the
event of any conveyance of title to the Building, then from and after the date
of such conveyance, the transferor Landlord shall be relieved of all liability
with respect to Landlord's obligations to be performed under this Lease after
the date of such conveyance, except that the transferor Landlord will not be
relieved of its obligation under this Lease to return any security deposit to
Tenant unless and until the transferor Landlord shall have transferred any such
security deposit to the successor Landlord. Notwithstanding any other term or
provision of this Lease, the liability of Landlord for its obligations under
this Lease is limited solely to Landlord's interest in the Building, including
insurance proceeds, as the same may from time to time be encumbered, and no
personal liability shall at any time be asserted or enforceable against any
other assets of Landlord or against Landlord's partners or members or its or
their respective partners, shareholders, members, directors, officers or
managers on account of any of Landlord's obligations or actions under this
Lease.

29.  CONSENTS AND APPROVALS.

     29.1 Determination in Good Faith. Wherever the consent, approval, judgment
          ---------------------------
or determination of Landlord is required or permitted under this Lease, Landlord
may exercise its good faith business judgment in granting or withholding such
consent or approval or in making such judgment or determination without
reference to any extrinsic standard of reasonableness, unless the provision
providing for such consent, approval, judgment or determination specifies that

                                       29
<PAGE>

Landlord's consent or approval is not to be unreasonably withheld, or that such
judgment or determination is to be reasonable, or otherwise specifies the
standards under which Landlord may withhold its consent. If it is determined
that Landlord failed to give its consent where it was required to do so under
this Lease, Tenant shall be entitled to injunctive relief but shall not to be
entitled to monetary damages or to terminate this Lease for such failure.

     29.2 No Liability Imposed on Landlord. The review and/or approval by
          --------------------------------
Landlord of any item or matter to be reviewed or approved by Landlord under the
terms of this Lease or any Exhibits or Addenda hereto shall not impose upon
Landlord any liability for the accuracy or sufficiency of any such item or
matter or the quality or suitability of such item for its intended use. Any such
review or approval is for the sole purpose of protecting Landlord's interest in
the Property, and no third parties, including Tenant or the Representatives and
Visitors of Tenant or any person or entity claiming by, through or under Tenant,
shall have any rights as a consequence thereof.

30.  BROKERS. Landlord shall pay the fee or commission of the broker or brokers
identified in the Basic Lease Information (the "Broker") in accordance with
Landlord's separate written agreement with the Broker, if any. Each party
warrants and represents to Landlord the other that in the negotiating or making
of this Lease neither party nor anyone acting on the behalf of the other party
has dealt with any broker or finder who might be entitled to a fee or commission
for this Lease other than the Broker. Each party shall indemnify and hold the
other harmless from any claim or claims, including costs, expenses and
attorney's fees incurred by the other party asserted by any other broker or
finder for a fee or commission based on any dealings with or statements made by
the indemnifying party.

32.  ENTIRE AGREEMENT. This Lease, including the Exhibits and any Addenda
attached hereto, and the documents referred to herein, if any, constitute the
entire agreement between

                                       30
<PAGE>

Landlord and Tenant with respect to the leasing of space by Tenant in the
Building, and supersede all prior or contemporaneous agreements, understandings,
proposals and other representations by or between Landlord and Tenant, whether
written or oral. Neither Landlord nor Landlord's agents have made any
representations or warranties with respect to the Premises, the Building, the
Project or this Lease except as expressly set forth herein, and no rights,
easements or licenses shall be acquired by Tenant by implication or otherwise
unless expressly set forth herein. The submission of this Lease for examination
does not constitute an option for the Premises and this Lease shall become
effective as a binding agreement only upon execution and delivery thereof by
Landlord to Tenant.

33. MISCELLANEOUS. This Lease may not be amended or modified except by a writing
signed by Landlord and Tenant. Subject to Section 14 - Assignment and Subletting
and Section 28 - Landlord's Liability, this Lease shall be binding on and shall
inure to the benefit of the parties and their respective successors, assigns and
legal representatives. The determination that any provisions hereof may be void,
invalid, illegal or unenforceable shall not impair any other provisions hereof
and all such other provisions of this Lease shall remain in full force and
effect. The unenforceability, invalidity or illegality of any provision of this
Lease under particular circumstances shall not render unenforceable, invalid or
illegal other provisions of this Lease, or the same provisions under other
circumstances. This Lease shall be construed and interpreted in accordance with
the laws (excluding conflict of laws principles) of the State in which the
Building is located. The provisions of this Lease shall be construed in
accordance with the fair meaning of the language used and shall not be strictly
construed against either party. When required by the context of this Lease, the
singular includes the plural. Wherever the term "including" is used in this
Lease, it shall be interpreted as meaning "including, but not limited to" the
matter or matters thereafter enumerated. The captions contained in this Lease
are for purposes of convenience only and are not to be used to interpret or
construe this Lease. If more than one person or entity is identified as Tenant
hereunder, the obligations of each and all of them under this Lease shall be
joint and several. Time is of the essence with respect to this Lease, except as
to the conditions relating to the delivery of possession of the Premises to
Tenant. Neither Landlord nor Tenant shall record this Lease.

34. AUTHORITY. If Tenant is a corporation, partnership, limited liability
company or other form of business entity, each of the persons executing this
Lease on behalf of Tenant warrants and represents that Tenant is a duly
organized and validly existing entity, that Tenant has full right and authority
to enter into this Lease and that the persons signing on behalf of Tenant are
authorized to do so and have the power to bind Tenant to this Lease. Tenant
shall provide Landlord upon request with evidence reasonably satisfactory to
Landlord confirming the foregoing representations.

35. CONDITION. The provisions of this Lease are subject to, conditioned upon and
shall not be effective unless and until Landlord and Easton Sports execute a
lease termination agreement by December 31, 1996. In the event the Easton Sports
termination has not been executed on or before December 31, 1996, then this
Lease shall be void and of no further force and effect. If the Easton Sports
termination is duly executed by December 31, 1996, Landlord shall confirm the
same in writing to Tenant.

Tenant's Plans, Landlord shall notify Tenant thereof and of any revisions that
Landlord reasonably requires in order to obtain Landlord's approval.

     Tenant shall contract directly with Landlord's contractor for the
construction and installation of the Tenant Improvements.

Lease to which they are attached. The capitalized terms used herein have the
same meanings as these terms are given in the Lease.

     1.    Use of Common Areas. Tenant will not obstruct the sidewalks, halls,
passages, exits, entrances, elevators or stairways of the Building ("Common
Areas"), and Tenant will not use the Common Areas for any purpose other than
ingress and egress to and from the Premises. The Common Areas, except for the
sidewalks, are not open to the general public and Landlord reserves the right to
control and prevent access to the Common Areas of any person whose presence, in
Landlord's opinion, would be prejudicial to the safety, reputation and interests
of the Building and its tenants.

     2.    No Access to Roof. Tenant has no right of access to the roof of the
Building and will not install, repair or replace any antenna, aerial, aerial
wires, fan, air-conditioner or other device on the roof of the Building, without
the prior written consent of Landlord. Any such device installed without such
written consent is subject to removal at Tenant's expense without notice at any
time. In any event Tenant will be liable for any damages or repairs incurred or
required as a result of its installation, use, repair, maintenance or removal of
such devices on the roof and agrees to indemnify and hold harmless Landlord from
any liability, loss, damage, cost or expense, including reasonable attorneys'
fees, arising from any activities of Tenant or of Tenant's Representatives on
the roof of the Building.

     3.    Signage. No sign, placard, picture, name, advertisement or notice
visible from the exterior of the Premises will be inscribed, painted, affixed or
otherwise displayed by Tenant on or in any part of the Building without the
prior written consent of Landlord. Landlord reserves the right to adopt and
furnish Tenant with general guidelines relating to signs in or on the Building.
All approved signage will be inscribed, painted or affixed at Tenant's expense
by a person approved by Landlord, which approval will not be unreasonably
withheld.

federal, state and city laws, codes, ordinances, roles and regulations. Tenant
may also use microwave ovens.

     5.    Janitorial Services. Tenant will not employ any person for the
purpose of cleaning the Premises or permit any person to enter the Building for
such purpose other than Landlord's janitorial service, except with Landlord's

cost of, any undue amount of janitorial labor by reason of Tenant's carelessness
in or indifference to the preservation of good order and cleanliness in the

elevator or stairs except during such hours and along such routes and by such
persons as may be designated by Landlord. Landlord reserves the right to require
that heavy objects will stand on wood strips of such length and thickness as is
necessary to properly distribute the weight. Landlord will not be responsible
for loss of or damage to any such property from any cause, and Tenant will be
liable for all damage or injuries caused by moving or maintaining such property.

     8.    Nuisances and Dangerous Substances. Tenant will not conduct itself or

Tenant will not use the name of the Building in connection with or in promoting
or advertising Tenant's business except as Tenant's address.

     10.   Building Directory. A directory for the Building will be provided for

tile, carpet or any other floor covering to the floor of the Premises in any

utilities are shut off before Tenant or its employees leave the Premises, so as
to prevent waste or damage. Tenant will be liable for all damage or injuries
sustained by other tenants or occupants of the Building or Landlord resulting
from Tenant's carelessness in this regard or violation of this role. Tenant will
keep the doors to the Building corridors closed at all times except for ingress
and egress.

<PAGE>

     16.   Use of Hand Trucks. Tenant will not use or permit to be used in the
Premises or in the Common Areas any hand trucks, carts or dollies except those
equipped with rubber tires and side guards or such other equipment as Landlord
may approve.

     17.   Refuse. Tenant shall store all Tenant's trash and garbage within the
Premises or in other facilities designated By Landlord for such purpose. Tenant
shall not place in any trash box or receptacle any material which cannot be
disposed of in the ordinary and customary manner of removing and disposing of
trash and garbage in the city in which the Building is located without being in
violation of any law or ordinance governing such disposal. All trash and garbage
removal shall be made in accordance with directions issued from time to time by
Landlord, only through such Common Areas provided for such purposes and at such
times as Landlord may designate. Tenant shall comply with the requirements of
any recycling program adopted by Landlord for the Building.

Tenant will cooperate to prevent the same.

     19.   Parking. Tenant will use, and cause Tenant's Representatives and
Visitors to use, the parking spaces to which Tenant is entitled under the Lease
in a manner consistent with Landlord's directional signs and markings in the
Parking Facility. Specifically, but without limitation, Tenant will not park, or
permit Tenant's Representatives or Visitors to park, in a manner that impedes
access to and from the Building or the Parking Facility or that violates space
reservations for handicapped drivers registered as such with the California
Department of Motor Vehicles. Landlord may use such reasonable means as may be
necessary to enforce the directional signs and markings in the Parking Facility,
including but not limited to towing services, and Landlord will not be liable
for any damage to vehicles towed as a result of noncompliance with such parking
regulations.

keeping doors locked and other means of entry to the Premises closed.

     22.   Sales and Auctions. Tenant will not conduct or permit to be conducted
any sale by auction in, upon or from the Premises or elsewhere in the Property,
whether said auction be voluntary, involuntary, pursuant to any assignment for
the payment of creditors or pursuant to any bankruptcy or other insolvency
proceeding.

     23.   Waiver of Rules. Landlord may waive any one or more of these Building
Rules for the benefit of any particular tenant or tenants, but no such waiver by
Landlord will be construed as a waiver of such Building Rules in favor of any
other tenant or tenants nor prevent

                                       4
<PAGE>

Landlord from thereafter enforcing these Building Rules against any or all of
the tenants of the Building.

     24.   Effect on Lease. These Building Rules are in addition to, and shall
not be construed to in any way modify or amend, in whole or in part, the terms,
covenants, agreements and conditions of the Lease. Violation of these Building
Rules constitutes a failure to fully perform the provisions of the Lease, as
referred to in Section 15.1 - "Events of Default".

     25.   Non-Discriminatory Enforcement. Subject to the provisions of the
Lease (and the provisions of other leases with respect to other tenants),
Landlord shall use reasonable efforts to enforce these Building Rules in a non-
discriminatory manner, but in no event shall Landlord have any liability for any
failure or refusal to do so (and Tenant's sole and exclusive remedy for any such
failure or refusal shall be injunctive relief preventing Landlord from enforcing
any of the Building Rules against Tenant in a manner that discriminates against
Tenant.

     26.   Additional and Amended Rules. Landlord reserves the right to rescind
or amend these Building Rules and/or adopt any other and reasonable rules and
regulations as in its judgment may from time to time be needed for the safety,
care and cleanliness of the Building and for the preservation of good order
therein.

                                                                Tenant KG

                       ATTACHED TO AND FORMING A PART OF
                                LEASE AGREEMENT
                         DATED AS OF DECEMBER 6, 1996
                                    BETWEEN
                 BAY PARK PLAZA ASSOCIATES, L.P., AS LANDLORD,
                                      AND
                 CROSSROADS SOFTWARE INC., AS TENANT ("LEASE")


                          ADDITIONAL PROVISIONS RIDER
                         ----------------------------

1.  Parking.
    -------

          (a) Landlord shall provide Tenant, on an unassigned, non-exclusive and
     unlabelled basis, sixty (60) parking spaces in the Parking Facility during
     the initial Term; provided, however, that ten percent (10%) of such spaces
     may be designated by Landlord as Building visitors' parking. If Tenant
     leases additional office space pursuant to this Lease, Landlord shall
     provide Tenant, also on an unassigned, non-exclusive and unlabelled basis,
     one (1) additional parking space in the Parking Facility for each three
     hundred (300) rentable square feet of additional office space leased to
     Tenant. Up to ten percent (10%) of such additional parking spaces may also
     be designated by Landlord as Building visitors' parking.

          (b) The parking spaces to be made available to Tenant hereunder may
     contain a reasonable mix of spaces for compact cars. Landlord shall take
     reasonable actions to ensure the availability of the parking spaces leased
     by Tenant, but Landlord does not guarantee the availability of those spaces
     at all times against the actions of other tenants of the Building and users
     of the Parking Facility. Access to the Parking Facility may, at Landlord's
     option, be regulated by card, pass, bumper sticker, decal or other
     appropriate identification issued by Landlord.

          (c) Assignment and Subletting. Notwithstanding the provisions of
              -------------------------
     Section 14 - "Assignment and Subletting" hereof, Tenant shall not assign
     its rights to the parking spaces or any interest therein, or sublease or
     otherwise allow the use of all or any part of the parking spaces to or by
     any other person, except with Landlord's prior-written consent, which may
     be granted or withheld by Landlord in its sole discretion or in connection
     with an assignment or subletting permitted under Section 14 of the Lease.
     In the event of any separate assignment or sublease of parking space rights
     that is approved by Landlord, Landlord shall be entitled to receive, as
     Additional Rent hereunder, one hundred percent (100%) of any profit
     received by Tenant in connection with such assignment or sublease.

          (d) Condemnation, Damage or Destruction. In the event the Parking
              -----------------------------------
     Facility is the subject of a Condemnation, or is damaged or destroyed, and
     this Lease is
<PAGE>

     not terminated, and if in such event the available number of parking spaces
     in the Parking Facility is permanently reduced, then Tenant's rights to use
     parking spaces hereunder may, at the election of Landlord, thereafter be
     reduced in proportion to the reduction of the total number of parking
     spaces in the Parking Facility. In such event, Landlord reserves the right
     to reduce the number of parking spaces to which Tenant is entitled or to
     relocate some or all of the parking spaces to which Tenant is entitled to
     other areas in the Parking Facility.

2.   Letter of Credit.
     ----------------

     Upon execution of this Lease, Tenant shall deliver to Landlord an
irrevocable standby letter of credit (the "Letter of Credit") in form, and
issued by a financial institution ("Issuer"), reasonably satisfactory to
Landlord. The Letter of Credit shall be in the amount of Three Hundred and
Thirty Two Thousand Dollars ($332,000.00), name Landlord as the beneficiary
thereunder, permit partial draws, and provide that draws thereunder will be
honored upon receipt by Issuer of a written statement signed by Landlord
specifying the amount to be paid by Issuer to Landlord and certifying that (i)
there exists an Event of Default as that term is defined in the Lease, (ii)
Landlord is entitled under the terms and conditions of the Lease to the payment
by Tenant of the amount specified, (iii) Landlord has applied the Security
Deposit held by Landlord identified in the Basic Lease Information in accordance
with Section 4 of the Lease and Tenant has not paid to Landlord the amount
required to replenish the Security Deposit as required by Section 4 of the
Lease. Landlord shall be entitled to draw the entire amount under the Letter of
Credit if Tenant does not deliver to Landlord an extension or replacement for
the Letter of Credit in substantially the form of the initial Letter of Credit
and in the amount then required under this Lease no later than one month before
the expiration date of the then existing Letter of Credit. Upon delivery of any
such replacement letter of credit, Landlord shall return to Tenant the original
Letter of Credit. Landlord shall be entitled to draw amounts under the Letter of
Credit required from time to time to cure any Event of Default under this Lease
or to compensate Landlord for any damage Landlord incurs as a result of Tenant's
failure to perform any of Tenant's obligations hereunder. If Landlord draws down
the entire amount of the Letter of Credit as set forth immediately above, then
Landlord shall hold such amount in a separate interest bearing account, as a
security deposit, subject to the provisions of Section 4 of this Lease (other
than the last sentence of Section 4) concerning the use and return of funds held
as a Security Deposit. All interest earned on such funds shall be maintained in
such interest bearing account and shall be paid to Tenant at the expiration or
sooner termination of this Lease. At Tenant's option, Tenant may instruct
Landlord to invest such funds in a conservative manner selected by Tenant which
will allow Landlord reasonable access to such funds, but will provide a higher
rate of return than an interest bearing account. All of the provisions herein
concerning relief from the obligation to maintain the Letter of Credit and to
reduce the amount of the Letter of Credit shall apply to such funds held by
Landlord. If the requirement of the Letter of Credit would be waived, Landlord
shall return such funds and all interest earned thereon to Tenant. If the
requirement for the amount of the Letter of Credit would be reduced, Landlord
shall return that portion of the funds to Tenant which is equal to the amount of
such reduction each time such reduction would occur.

     Landlord shall release the Letter of Credit at the end of the sixtieth
(60th) month of the Term if, as of such date, no Event of Default on the part of
Tenant then exists and no event or

                                       2
<PAGE>

condition then exists which, with notice or the passage of time, would become an
Event of Default on the part of Tenant. Promptly following Tenant's cure of any
such Event of Default or default of which Landlord has given Tenant written
notice, Landlord shall release the Letter of Credit. The amount of the Letter of
Credit shall be reduced on the second (2nd) anniversary of the Commencement Date
by the amount of Sixty-Six Thousand Four Hundred Dollars ($66,400), provided
that on the anniversary date in question there exists neither an Event of
Default or an event or condition which, with notice or the passage of time,
would become an Event of Default on the part of Tenant.

3.   Warrants. As additional consideration for Landlord's execution of this
     --------
Lease, Tenant has agreed to issue to Landlord, promptly following the execution
of this Lease, warrants to purchase shares of Tenant's common stock, exercisable
by Landlord at any time during the Term of this Lease. This Lease shall not be
effective as a binding agreement between Landlord and Tenant unless and until a
Stock Purchase Warrant satisfactory to Landlord, in Landlord's sole and absolute
discretion, shall have been properly authorized and issued by Tenant to Landlord
and accepted by Landlord. If no such Stock Purchase Warrant shall have been so
issued and accepted by 5:00 p.m. on December 13, 1996, this Lease shall
automatically be null and void.

4.   Extension Option
     ----------------

     Provided that Tenant has not assigned this Lease or sublet any or all of
the Premises (it being intended that all rights pursuant to this provision are
and shall be personal to the original Tenant under this Lease and shall not be
transferable or exercisable for the benefit of any Transferee), and provided
Tenant is not in default under this Lease at the time of exercise or at any
other time thereafter until the beginning of any such extension of the Term,
Tenant shall have the option (the "Extension Option") to extend the Term for one
additional consecutive period of five (5) years ("Extension Period"), by giving
written notice to Landlord of the exercise of any such Extension Option at least
twelve (12) months prior to the expiration of the initial Term. The exercise of
any Extension Option by Tenant shall be irrevocable and shall cover the entire
Premises then leased by Tenant pursuant to this Lease. Upon such exercise,
Landlord shall have the right to review and approve, in Landlord's sole
discretion, Tenant's financial condition and creditworthiness at such time. If
Landlord approves Tenant's financial condition and creditworthiness, Landlord
shall so notify Tenant, and the Term of the Lease shall be extended for the
applicable Extension Period without the execution of any further instrument by
the parties; provided that Landlord and Tenant shall, if requested by either
party, execute and acknowledge and instrument confirming the exercise of the
Extension Option. Any Extension Option shall terminate if not exercised
precisely in the manner provided herein. Any extension of the Term shall be upon
all the terms and conditions set forth in this Lease and all Exhibits thereto,
except that:(i) Tenant shall have no further option to extend the Term of the
Lease, other than as specifically set forth herein; (ii) Landlord shall not be
obligated to contribute funds toward the cost of any remodeling, renovation,
alteration or improvement work in the Premises; and (iii) Base Rent for any such
Extension Period shall be 100% of the then "Fair Market Base Rental" (as defined
below) for the Premises for the space and term involved, which shall be
determined as set forth below.

                                       3
<PAGE>

     (a) "Fair Market Base Rental" shall mean the "fair market" Base Rent at the
time or times in question for the applicable space, based on the prevailing
rentals then being charged to new tenants in the Building and new tenants in
other office buildings in the general vicinity of the Building of comparable
size, location, quality and age as the Building for leases with terms equal to
the Extension Period, taking into account the then-condition of the Premises,
the amount of any leasing commission payable with respect to the Option Period,
the creditworthiness and financial strength of the tenant, the financial
guaranties provided the tenant (if any), the value of market concessions
(including the value of construction, renovations, moving and other allowances
or rent credits), the desirability, location in the building, size and quality
of the space, tenant finish and/or improvement allowance and/or tenant
improvements, included services, operating expenses, and tax and expense stops
or other escalation clauses, for the space in the Building for which Fair Market
Base Rental is being determined and for comparable space in the buildings which
are being used for comparison. Fair Market Base Rental shall also reflect the
then prevailing rental structure of comparable office buildings in the general
vicinity of the Property, so that if, for example, at the time Fair Market Base
Rental is being determined the prevailing rental structure of comparable space
and for comparable lease terms includes periodic rental adjustments or
escalations, Fair Market Base Rental shall reflect such rental structure.

     (b) Landlord and Tenant shall endeavor to agree upon the Fair Market Base
Rental. If they are unable to so agree within thirty (30) days after receipt by
Landlord of Tenant's notice of exercise of the Extension Option, Landlord and
Tenant shall mutually select a licensed real estate broker who is active in the
leasing of office space in the general vicinity of the Property. Landlord shall
submit Landlord's determination of Fair Market Base Rental and Tenant shall
submit Tenant's determination of Fair Market Base Rental to such broker, at such
time or times and in such manner as Landlord and Tenant shall agree (or as
directed by the broker if Landlord and Tenant do not promptly agree). The broker
shall select either Landlord's or Tenant's determination as the Fair Market Base
Rental, and such determination shall be binding on Landlord and Tenant. If
Tenant's determination is selected as the Fair Market Base Rental, then Landlord
shall bear all of the broker's cost and fees. If Landlord's determination is
selected as the Fair Market Base Rental, then Tenant shall bear all of the
broker's cost and fees.

     (c) In the event the Fair Market Base Rental for any Extension Period has
not been determined at such time as Tenant is obligated to pay Base Rent for
such Extension Period, Tenant shall pay as Base Rent pending such determination,
the Base Rent in effect for such space immediately prior to the Extension
Period; provided, that upon the determination of the applicable Fair Market Base
Rental, any shortage of Base Rent paid, together with interest at the rate
specified in the Lease, shall be paid to Landlord by Tenant.

                                       4
<PAGE>

     (d) In no event shall the Base Rent during any Extension Period be less
than the Base Rent in effect immediately prior to such Extension Period.

     (e) The term of this Lease, whether consisting of the Initial Term alone or
the Initial Term as extended by any Extension Period (if any Extension Option is
exercised), is referred to in this Lease as the "Term".

                                                                 Tenant KG

                                                                 Landlord JH

building known as Bay Park Plaza I (the "Building") located at 577 Airport
Boulevard, Burlingame, California 94010.

     B. Landlord and Tenant desire that Tenant lease from Landlord two (2)
different spaces (in addition to the Existing Premises) in the Building pursuant
to the provisions of the Lease, as amended by this Agreement, such spaces being
identified as (i) Suite 500 (the "First Expansion Premises") containing
approximately 17,783 square feet of Rentable Area, and (ii) Suite 600 (the
"Second. Expansion Premises") containing approximately 4,814 square feet of
Rentable Area. Together, the First Expansion Premises and the Second Expansion
Premises are sometimes herein referred to the "Expansion Premises." The
approximate size and location of the First Expansion Premises is shown on
Exhibit A (a) and the approximate size and location of the Second Expansion
Premises is shown on Exhibit A (b) attached hereto.

     D. Tenant acknowledges that it has been informed by Landlord that the First
Expansion Premises is currently leased by a tenant pursuant to a lease which
expires April 23, 1998; and that the Second Expansion Premises is currently
leased by a tenant pursuant to a lease which expires June 30, 1998 and that the
tenant leasing the Second Expansion Premises has vacated the Second Expansion
Premises.

     E. The Term of the Lease is scheduled to expire January 31, 2002, and in
connection with Tenant leasing the Expansion Premises pursuant to the provisions
of this Agreement, Landlord and Tenant desire to extend the Term of the Lease,
and to make certain other changes, all as more specifically contained
hereinbelow.

     NOW THEREFORE, in consideration of the above recitals, the mutual promises
contained herein, and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto agree as

1)   All capitalized terms not defined herein shall have the meaning set forth
     in the Lease.

                                       1
<PAGE>

2)   Landlord agrees to use its good faith efforts to enter into early lease
     termination agreements with the tenant leasing the First Expansion Premises
     and the tenant leasing the Second Expansion Premises, to terminate such
     leases prior to their existing expiration dates; provided, however, nothing
     contained herein shall obligate Landlord to pay any sum to either of such
     existing tenants to terminate their leases prior to the existing expiration
     dates. If, despite Landlord's good faith efforts, Landlord is not able to
     enter into early lease termination agreements with the tenants leasing the
     First Expansion Premises and the Second Expansion Premises to terminate
     such leases prior to their respective existing expiration dates, Landlord
     shall not be liable to Tenant for any such failure to terminate such leases
     prior to their existing expiration dates.

3)   Landlord hereby leases to Tenant, and Tenant leases from Landlord,
     commencing upon the First Expansion Premises Commencement Date (as
     hereinafter defined) and continuing through the Term (as hereinafter
     extended) the First Expansion Premises. Landlord hereby leases to Tenant,
     and Tenant leases from Landlord, commencing upon the Second Expansion
     Premises Commencement Date (as hereinafter defined) and continuing through
     the Term (as hereinafter extended) the Second Expansion Premises. Landlord
     agrees to give Tenant possession of the First Expansion Premises when the
     First Expansion Premises has been vacated after the earlier to occur of (a)
     the expiration of the lease with the tenant currently leasing the First
     Expansion Premises, or (b) the complete execution of any early termination
     agreement terminating the lease with such tenant currently leasing the
     First Expansion Premises. Landlord agrees to give Tenant possession of the
     Second Expansion Premises after the earlier to occur of (a) the expiration
     of the lease with the tenant currently leasing the Second Expansion
     Premises, or (b) the complete execution of any early termination agreement
     terminating the lease with such tenant currently leasing the Second
     Expansion Premises.

4)   Tenant has inspected the First Expansion Premises and the Second Expansion
     Premises and shall take both Expansion Premises in their existing "AS IS"
     condition, without any obligation by Landlord to construct any Tenant
     Improvements in the Expansion Premises or for Landlord to contribute to the
     costs of Tenant Improvements in the Expansion Premises, except for the
     payment of an Allowance in connection with Tenant constructing Tenant
     Improvements in the First Expansion Premises, as specifically contained in
     the next succeeding paragraph.

5)   Tenant shall be responsible for designing, constructing and installing all
     Tenant Improvements in the Expansion Premises in accordance with the
     provisions of Paragraph 2 of Exhibit B to the Lease and Section 6 of the
     Lease. Tenant shall contract directly with Commercial Interior Contractors
     ("CIC") for construction of Tenant Improvements in the Expansion Premises.
     Tenant acknowledges that CIC is an affiliate of Landlord. Landlord shall
     contribute up to $5.00 per square foot of Rentable Area in the First
     Expansion Premises (the "Allowance") toward the cost of the design
     (including preparation of space plans and Construction Documents),
     construction and

                                       2
<PAGE>

     installation of the Tenant Improvements in the First Expansion Premises,
     such Allowance to be paid upon Tenant completing the Tenant Improvements in
     the First Expansion Premises. The balance, if any, of the cost of the
     Tenant Improvements, including, but not limited to, usual markups for
     overhead, supervision and profit, shall be paid by Tenant to CIC pursuant
     to Tenant's contract with CIC.

6)   The First Expansion Premises Commencement Date shall be the earlier of (a)
     sixty (60) days after the date Landlord delivers possession of the First
     Expansion Premises to Tenant (which date may be prior to the date of the
     Second Expansion Premises Commencement Date) after the tenant currently
     occupying the First Expansion Premises has vacated the First Expansion
     Premises pursuant to the provisions of Paragraph 2 above, or (b) any
     earlier date upon which Tenant, with Landlord's written permission,
     actually occupies and conducts business in any portion of the First
     Expansion Premises.

7)   The Second Expansion Premises Commencement Date shall be the date Landlord
     delivers possession of the Second Expansion Premises to Tenant (which date
     may be prior to the date of the First Expansion Premises Date) after the
     tenant currently occupying the Second Expansion Premises has vacated the
     Second Expansion Premises pursuant to the provisions of Paragraph 2 above.

8)   The Term of the Lease shall be extended to be one hundred twenty (120) full
     calendar months (plus any partial month of the Term) following the First
     Expansion Premises Commencement Date; and the Term shall expire on the last
     day of the one hundred twentieth (120th) full calendar month following the
     First Expansion Premises Commencement Date.

9)   Base Rent for the Expansion Premises. Reference is hereby made to Article 3
     ------------------------------------
     of the Lease. In addition to the Base Rent payable by Tenant for the
     Existing Premises pursuant to the provisions of the Lease in effect prior
     to the date of this Agreement, from and after the First Expansion Premises
     Commencement Date (with respect to the First Expansion Premises), and the
     Second Expansion Premises Commencement Date (with respect to the Second
     Expansion Premises) and continuing through the remainder of the Term
     (subject to annual increases in accordance with the provisions of Paragraph
     10 below), Tenant shall pay to Landlord, in accordance with the provisions
     of Section 3.1 of the Lease, $2.75 per month per square foot of Rentable
     Area in the Expansion Premises as Base Rent for the Expansion Premises.

     Base Rent for any partial month following the respective Expansion Premises
     Commencement Date shall be prorated based on the actual number of days in
     the month.

10)  The following new provision is hereby added to the Lease:

                                       3
<PAGE>

     COST OF LIVING ADJUSTMENTS.

          (a) Subject to the restriction on increases in Base Rent for the
     Existing Premises prior to January 31, 2002 contained in Paragraph 11
     below, the Base Rent per month per square foot of Rentable Area shall be
     increased effective on each anniversary of the First Expansion Premises
     Commencement Date (each anniversary being an "Adjustment Date"), to reflect
     increases in the cost of living. The adjustment shall be calculated by
     multiplying the average Base Rent per month per square foot of Rentable
     Area for the twelve (12) month period immediately preceding the Adjustment
     Date (the "Prior Period") by the percentage increase in the Consumer Price
     Index, measured from (i) the last calendar month for which the Consumer
     Price Index was published at least one hundred twenty (120) days
     immediately before the commencement of the Prior Period to (ii) the same
     calendar month immediately prior to the end of the Prior Period; provided,
     however, that on each Adjustment Date the Base Rent per month per square
     foot of Rentable Area shall be increased by a minimum of three percent (3%)
     per annum, cumulative, from the First Expansion Premises Commencement Date
     or the prior Adjustment Date, as applicable, and by a maximum of six
     percent (6%) per annum, cumulative, from the First Expansion Premises
     Commencement Date or the prior Adjustment Date, as applicable. The Base
     Rent per month per square foot of Rentable Area for each twelve (12) month
     period after the first Adjustment Date shall be the Base Rent per month per
     square foot of Rentable Area for the Prior Period plus the increase
     calculated in accordance with the preceding sentence. In no event shall the
     Base Rent per month per square foot of Rentable Area following any such
     adjustment be less than the Base Rent per month per square foot of Rentable
     Area in effect immediately prior to such adjustment.

          (b) The term "Consumer Price Index" means the United States Department
     of Labor's Bureau of Labor Statistics' Consumer Price Index, All Urban
     Consumers, All Items, San Francisco-Oakland-San Jose, California
     (1982-84=100), or the successor of such index.

          (c) If the Consumer Price Index is not published by the Bureau of
     Labor Statistics or another governmental agency for any month for which an
     adjustment in the Consumer Price Index is to be measured, then the
     foregoing calculations shall be made using the most closely comparable
     statistics on the purchasing power of the consumer dollar as published by a
     responsible financial authority selected by Landlord.

          (d) If the adjustment provided for in this Section has not been made
     by any Adjustment Date, Tenant shall continue to pay monthly Base Rent at
     the rate applicable to the Prior Period. Within fifteen (15) days after
     Tenant receives Landlord's written notice of the adjusted Base Rent for the
     then-current Adjustment Date, Tenant shall pay to Landlord the shortfall
     between the old Base Rent, as paid by Tenant to date for the then-current
     Lease period, and the new Base Rent payable from the beginning of

                                       4
<PAGE>

     the then-current Lease period through the date of Landlord's notice.
     Thereafter during such Lease period, Tenant shall pay the Base Rent per
     month per square foot of Rentable Area at the new rate set forth in
     Landlord's notice.

11)  Base Rent for the Existing Premises. Continuing through January 31, 2002
     -----------------------------------
     Tenant shall continue to pay Base Rent for the Existing Premises in
     accordance with the provisions of the Lease in effect prior to the date of
     this Agreement (without any increase pursuant to the provisions of
     Paragraph 10 above prior to January 31, 2002). Commencing February 1, 2002,
     Tenant shall pay to Landlord for the Existing Premises the same Base Rent
     per month per square foot of Rentable Area contained in the Existing
     Premises as Tenant is required to pay per month per square foot of Rentable
     Area in the Expansion Premises effective February 1, 2002 pursuant to the
     provisions of Paragraph 9 above, as increased pursuant to the provisions of
     Paragraph 10 above. Thereafter, Base Rent for the Existing Premises shall
     increase on the same date, and in the same manner, as Base Rent for the
     Expansion Premises increases pursuant to the provisions of Paragraph 10
     above.

12)  Reference is hereby made to Section 4.01 of the Lease. The Base Year for
     the entire Premises, including the Existing Premises, shall be calendar
     year 1998.

13)  If the First Expansion Premises Commencement Date occurs prior to the
     Second Expansion Premises Commencement Date, then upon the First Expansion
     Premises Commencement Date, Tenant's Share shall be 25.53%. If the Second
     Expansion Premises Commencement Date occurs prior to the First Expansion
     Premises Commencement Date, then upon the Second Expansion Premises
     Commencement Date, Tenant's Share shall be 16.26%. Tenant's Share shall be
     28.97% upon such date both the First Expansion Premises Commencement Date
     and the First Expansion Premises Commencement Date has occurred, whichever
     is later.

14)  Letter of Credit. Within fifteen (15) days after Tenant executes this
     ----------------
     Agreement Tenant shall deliver to Landlord, subject to the provisions of
     Paragraph 2 of the Additional Provisions Rider to the Lease, either (a) an
     amendment to the existing Letter of Credit increasing the amount of the
     existing Letter of Credit by Ninety Thousand and 00/100 Dollars
     ($90,000.00), or (b) in addition to the existing Letter of Credit, a new
     Letter of Credit in the amount of Ninety Thousand and 00/100 Dollars
     ($90,000.00).

15)  Tenant warrants and represents to Landlord that in the negotiating or
     making of this Agreement neither Tenant nor anyone acting on Tenant's
     behalf has dealt with any broker or finder who might be entitled to a fee
     or commission for this Agreement. Tenant shall indemnify and hold Landlord
     harmless from any claim or claims, including costs, expenses and attorney's
     fees incurred by Landlord asserted by any other broker or finder for a fee
     or commission based upon any dealings with or statements made by Tenant or
     Tenant's Representatives.

                                       5

     Except as herein amended, the Lease remains unchanged and is in full force
and effect in accordance with the terms and provisions contained therein.

     This First Amendment is hereby executed and delivered in multiple
counterparts, each of which shall have the force and effect of an original.

                 CONDITIONAL PARTIAL LEASE TERMINATION AGREEMENT
                 -----------------------------------------------

         THIS CONDITIONAL PARTIAL LEASE TERMINATION AGREEMENT ("Agreement") is
made as of March 29, 1999 by and between BAY PARK PLAZA ASSOCIATES, LLC, a
California limited liability company ("Landlord"), and CROSSWORLDS SOFTWARE,
INC., a Delaware corporation ("Tenant").

                                    RECITALS

     A. Landlord and Tenant entered into a Lease Agreement dated December 6,
1996 (as amended by a First Amendment of Lease dated November 13, 1997 and a
Second Amendment of Lease dated March 16, 1998, as so amended, the "Lease"),
under the terms of which Lease Landlord leased to Tenant and Tenant leased from
Landlord certain premises (the "Premises") consisting of approximately 47,857
rentable square feet of office space on the 2nd, 5th, 6th and 8th floors of the
building commonly known as Bay Park Plaza (the "Building"), located at 577
Airport Boulevard, Burlingame, CA 94010.

     B. The term of the Lease is scheduled to expire on April 30, 2008.

     C. Subject to, and conditioned upon (i) Landlord entering into leases with
one or more replacement tenants for all portions of the Termination Space (as
hereinafter defined), and (ii) Tenant paying to Landlord the Early Termination
Fee (as hereinafter defined) within the time and in accordance with the
provisions contained herein, Landlord and Tenant desire mutually to partially
terminate the Lease only with respect to the Termination Space, such partial
termination being effective, if at all, as of April 1, 1999 (the "Early
Termination Date"), upon and subject to the terms and conditions of this
Agreement.

     D. The Termination Space shall consist of Suite 620 containing
approximately 3,365 rentable square feet in the Building. The approximate
location and configuration of the Termination Space is shown on Exhibit A
attached hereto and made a part hereof.

     NOW, THEREFORE, in consideration of the foregoing Recitals and the mutual
covenants contained herein, and subject to the condition set forth in Paragraph
3 herein, Landlord and Tenant hereby agree as follows:

     1. CONDITIONAL PARTIAL TERMINATION OF LEASE. Provided that (i) Landlord has
entered into leases with one or more replacement tenants for the entire
Termination Space on or before April 15, 1999 and (ii) Tenant has paid to
Landlord the Early Termination Fee on or before the date contained in Paragraph
3 below, the Lease shall terminate only with respect to the Termination Space on
the Early Termination Date. Notwithstanding any partial termination of the Lease
with respect to the Termination Space in accordance with the provisions of this
Agreement, the Lease shall remain in full force and effect in accordance with
its terms for the remaining portion of the Premises not terminated in accordance
with the terms of this Agreement. Upon any such partial termination of the Lease
Tenant shall vacate and surrender the Termination Space no later than the Early
Termination Date in accordance with the terms of the Lease and warrant that

                                       1
<PAGE>

any and all subtenants or co-occupants of the Termination Space shall vacate and
surrender the Termination Space no later than the Early Termination Date in
accordance with the terms of the Lease. Notwithstanding any partial termination
of the Lease in accordance with this Agreement, Tenant shall remain liable for
all obligations of Tenant accruing under the Lease through the later of (x) the
Early Termination Date, or (y) the date Tenant, and all subtenants actually
vacate the Termination Space.

     2. REMEDIES. Upon Landlord notifying Tenant that Landlord has entered into
one or more leases with replacement tenants for the entire Termination Space on
or before April 15, 1999, if Tenant, and all subtenants of the Termination
Space, fail to vacate and surrender the Termination Space by the Early
Termination Date:(i) Landlord shall have all of the rights and remedies provided
in the Lease for failure to vacate and surrender the Premises upon expiration or
termination of the Lease, and Tenant shall be liable to and shall indemnify
Landlord as provided in the Lease; or (ii) Landlord, at Landlord's sole option,
by written notice to Tenant, may rescind the Conditional Partial Termination of
the Lease, whereupon the Lease with respect to the Termination Space shall be
reinstated and Tenant shall remain responsible for all of Tenant's obligations
thereunder, including those obligations that would have accrued during the
period from the Early Termination Date to the date of the reinstatement of the
Lease with respect to the Termination Space. In addition, if Tenant (directly or
through any Transferee or other successor-in-interest of Tenant) remains in
possession of the Termination Space after the Early Termination Date, Tenant's
continued possession shall be on the basis of a tenancy at the sufferance of
Landlord. No act or omission by Landlord, other than its specific written
consent, shall constitute permission for Tenant to continue in possession of the
Termination Space, and if such consent is given or declared to have been given
by a court judgment, Landlord may terminate Tenant's holdover tenancy in the
Termination Space at any time upon seven (7) days written notice. In such event,
Tenant shall continue to comply with or perform all the terms and obligations of
Tenant under the Lease, except that the monthly Base Rent during Tenant's
holding over in the Termination Space shall be twice the Base Rent payable in
the last full month prior to the partial termination of the Lease with respect
to the Termination Space. Acceptance by Landlord of rent after such termination
shall not constitute a renewal or extension of the Lease with respect to the
Termination Space; and nothing contained in this provision shall be deemed to
waive Landlord's right of re-entry or any other right hereunder or at law.
Tenant shall indemnify, defend and hold Landlord harmless from and against all
claims arising or resulting directly or indirectly from the failure of Tenant
and the sublessees to timely surrender the Termination Space, including (i) any
rent payable by or any loss, cost, or damages claimed by any prospective tenant
of the Termination Space, and (ii) Landlord's damages as a result of such
prospective tenant rescinding or refusing to enter into the prospective lease of
the Termination Space by reason of such failure to timely surrender the
Termination Space.

     3. ADDITIONAL CONDITION TO PARTIAL LEASE TERMINATION. Within ten (10) days
after the date Landlord has notified Tenant that Landlord has entered into one
or more leases with replacement tenants for the entire Termination Space Tenant
shall pay to Landlord the sum of Thirty-three Thousand Six Hundred Fifty and
00/100 Dollars ($33,650.00) as an "Early Termination Fee" for the partial
termination of the Lease with

                                       2
<PAGE>

respect to the Termination Space. The provisions of Paragraph 1 (Termination)
are subject to, conditioned upon and shall not be effective unless and until
Tenant has paid to Landlord the Early Termination Fee.

     4. SUBLEASE/ASSIGNMENT. Except for Tenant's subleasing of the Termination
Space which Tenant has disclosed in writing to Landlord prior to the date of
this Agreement, each party represents to the other that it has not made any
assignment, sublease, transfer, conveyance, or other disposition of the Lease or
any interest in the Lease or the Termination Space.

     5. GENERAL PROVISIONS. This Agreement shall be governed by the laws of the
State of California, without regard to conflict of laws principles. In the event
a dispute arises concerning the enforcement or interpretation of this Agreement,
the prevailing party in such dispute will be entitled to recover from the
opposing party all costs and expenses incurred by the prevailing party,
including court or arbitration costs and reasonable attorney's fees. The
"prevailing party" will be the party that the court or arbitrator hearing the
dispute determines to have prevailed, based upon assessing which party's major
arguments could fairly be said to have prevailed over the other party's major
arguments on major disputed issues. This Agreement will be binding upon and
inure to the benefit of the heirs, representatives, successors in interest and
assigns of the respective parties to this Agreement. Each party agrees to
cooperate with each other and to execute and deliver all such further written
instruments and documents and do all such further acts and things that such
party may be reasonably requested to do from time to time by the other party in
order to carry out the provisions and objectives of this Agreement.

     6. ENTIRE AGREEMENT. This Agreement contains the entire agreement between
Landlord and Tenant relating to the partial termination of the Lease with
respect to the Termination Space, and may be modified only by a writing signed
by Landlord and Tenant.

     IN WITNESS WHEREOF, Landlord and Tenant have entered in this Agreement as
of the date first above written.

performance of the Loan Documents are within Borrower's powers, have been duly
authorized, and are not in conflict with nor constitute a breach of any
provision contained in Borrower's Articles of Incorporation or Bylaws, nor will
they constitute an event of default under any material agreement to which
Borrower is a party or by which Borrower is bound. Borrower is not in default
under any agreement to which it is a party or by which it is bound, which
default would reasonably be expected to have a Material Adverse Effect.

          5.3. No Prior Encumbrances. Borrower has good and indefeasible title

Borrower does not have knowledge of any such pending or threatened actions or
proceedings.

Effect. Borrower is not an "investment company" or a company "controlled" by an
"investment company" within the meaning of the Investment Company Act of 1940.
Borrower is not engaged principally, or as one of the important activities, in
the business of extending credit for the purpose of purchasing or carrying

results may differ from such projections or forecasts.

<PAGE>

and local, state, and federal income taxes, and will, upon request, furnish Bank
with proof satisfactory to Bank indicating that Borrower or a Subsidiary, has
made such payments or deposits; provided that Borrower or a Subsidiary need not
make any payment if the amount or validity of such payment is contested in good
faith by appropriate proceedings and is reserved against (to the extant required
by GAAP) by Borrower.

          6.6.  Insurance.
                ---------

within a reasonable time, then Borrower shall have an additional reasonable
period (which shall not in any case exceed thirty (30) days) to attempt to cure

which are authorized by Borrower:

               (a) Declare all Obligations, whether evidenced by this Agreement,
by any of the other Loan Documents, or otherwise, immediately due and payable
(provided that upon the occurrence of an Event of Default described in Section
8.5 all Obligations shall become immediately due and payable without any action
by Bank);

               (b) Cease advancing money or extending credit to or for the
benefit of Borrower under this Agreement or under any other agreement between
Borrower and Bank;

               (c) Settle or adjust disputes and claims directly with account
debtors for amounts, upon terms and in whatever order that Bank reasonably
considers advisable;

               (d) Without notice to or demand upon Borrower, make such payments
and do such acts as Bank considers necessary or reasonable to protect its
security interest in the Collateral. Borrower agrees to assemble the Collateral
if Bank so requires, and to make the Collateral available to Bank as Bank may
designate. Borrower authorizes Bank to enter the premises where the Collateral
is located, to take and maintain possession of the Collateral, or any part of
it, and to pay, purchase, contest, or compromise any encumbrance, charge, or
lien which in Bank's determination appears to be prior or superior to its
security interest and to pay all expenses incurred in connection therewith. With
respect to any of Borrower's owned premises, Borrower hereby grants Bank a
license to enter into possession of such premises and to occupy the same,
without charge, for up to one
<PAGE>

hundred twenty (120) days in order to exercise any of Bank's rights or remedies
provided hereto, at law, in equity, or otherwise;

               (e) Without notice to Borrower set off and apply to the
Obligations any and all (i) balances and deposits of Borrower held by Bank, or

Borrower held by Bank;

               (f) Ship, reclaim, recover, store, finish, maintain, repair,
prepare for sale, advertise for sale, and sell (in the manner provided for
herein) the Collateral. Bank is hereby granted a license or other right, solely
pursuant to the provisions of this Section 9.1, to use, without charge,
Borrower's labels, patents, copyright, rights of use of any name, trade secrets,
trade names, trademarks, service marks, and advertising matter, or any property
of a similar nature, as it pertains to the Collateral, in completing production
of, advertising for sale, and selling any Collateral and, in connection with
Bank's exercise of its rights under this Section 9.1, Borrower's rights under
all licenses and all franchise agreements shall inure to Bank's benefit;

               (g) Sell the Collateral at either a public or private sale, or
both, by way of one or more contracts or transactions, for cash or on terms, in
such manner and at such places (including Borrower's premises) as Bank
determines is commercially reasonable, and apply any proceeds to the Obligations
in whatever manner or order Bank deems appropriate;

               (h) Bank may credit bid and purchase at any public sale; and

               (i) Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.

          9.2. Power of Attorney. Effective only upon the occurrence and during
               -----------------
the continuance of an Event of Default, Borrower hereby irrevocably appoints
Bank (and any of Bank's designated officers, or employees) as Borrower's true
and lawful attorney to: (a) send requests for verification of Accounts or notify
account debtors of Bank's security interest in the Accounts; (b) endorse
Borrower's name on any checks or other forms of payment or security that may
come into Bank's possession; (c) sign Borrower's name on any invoice or bill of
lading relating to any Account, drafts against account debtors, schedules and
assignments of Accounts, verifications of Accounts, and notices to account
debtors; (d) make, settle, and adjust all claims under and decisions with
respect to Borrower's policies of insurance; and (e) settle and adjust disputes
and claims respecting the accounts directly with account debtors, for amounts
and upon terms which Bank determines to be reasonable; provided Bank may
exercise such power of attorney to sign the name of Borrower on any of the
documents described in Section 4.2 regardless of whether an Event of Default has
occurred. The appointment of Bank as Borrower's attorney in fact, and each and
every one of Bank's rights and powers, being coupled with an interest, is
irrevocable until all of the Obligations have been fully repaid and performed
and Bank's obligation to provide advances hereunder is terminated.

          9.3. Accounts Collection. Upon the occurrence and during the
               ------------------
continuance of an Event of Default, Bank may notify any Person owing funds to
Borrower of Bank's security interest in such funds and verify the amount of such
Account. Borrower shall collect all amounts owing to Borrower for Bank, receive
in trust all payments as Bank's trustee, and immediately deliver such payments
to Bank in their original form as received from the account debtor, with proper
endorsements for deposit.

          9.4. Bank Expenses. If Borrower fails to pay any amounts or furnish
               -------------
any required proof of payment due to third persons or entities, as required
under the terms of this Agreement, then Bank may do any or all of the following
(a) make payment of the same or any part thereof; (b) set up such reserves under
the Revolving Facility as Bank deems necessary to protect Bank from the exposure
created by such failure; or (c) obtain and maintain insurance policies of the
type discussed in
<PAGE>

Section 6.6 of this Agreement, and take any action with respect to such policies
as Bank deems prudent. Any amounts so paid or deposited by Bank shall constitute
Bank Expenses, shall be immediately due and payable, and shall bear interest at
the then applicable rate hereinabove provided, and shall be secured by the
Collateral. Any payments made by Bank shall not constitute an agreement by Bank
to make similar payments in the future or a waiver by Bank of any Event of
Default under this Agreement.

          9.5. Bank's Liability for Collateral. So long as Bank complies with
               -------------------------------
Section 9207 of the Code, Bank shall not in any way or manner be liable or
responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage
thereto occurring or arising in any manner or fashion from any cause; (c) any
diminution in the value thereof: or (d) any act or default of any carrier,
warehouseman, bailee, forwarding agency, or other person whomsoever. Subject to
the foregoing, all risk of loss, damage or destruction of the Collateral shall
be borne by Borrower.

          9.6. Remedies Cumulative. Bank's rights and remedies under this
               -------------------
Agreement, the Loan Documents, and all other agreements shall be cumulative.
Bank shall have all other rights and remedies not inconsistent herewith as
provided under the Code, by law, or in equity. No exercise by Bank of one right
or remedy shall be deemed an election, and no waiver by Bank of any Event of
Default on Borrower's part shall be deemed a continuing waiver. No delay by Bank
shall constitute a waiver, election, or acquiescence by it. No waiver by Bank
shall be effective unless made in a written document signed on behalf of Bank
and then shall be effective only in the specific instance and for the specific
purpose for which it was given.

          9.7. Demand: Protest. Borrower waives demand, protest, notice of
               ---------------
protest, notice of dishonor, notice of payment and nonpayment, notice of any
default, nonpayment at maturity, release, compromise, settlement, extension, or-
renewal of accounts, documents, instruments, chattel paper, and guarantees at
any time held by Bank on which Borrower may in any way be liable.

                 ---------------------
is the sole owner of the Intellectual Property Collateral, and, except for non-
exclusive licenses granted by Borrower in the ordinary course of business,
Borrower has not granted any liens, encumbrances, or other security interests in
the Intellectual Property Collateral. To the best of Borrower's knowledge, each
of the Patents is valid and enforceable. No part of the Intellectual Property
Collateral has been judged invalid or unenforceable, in whole or in part, and no
claim has been made that any part of the Intellectual Property Collateral
violates the rights of any third party."

     8.   The following new Section 6.3(a)(vi) is hereby added as follows:

          "(vi) within fifteen (15) days after the end of each fiscal quarter,

limited to, any subsequent ownership right of the Borrower in or to any Patents
relating to material patentable inventions, Trademarks and Copyrights relating
to major software releases not specified in any intellectual property security
agreement between Borrower and Bank or knowledge of an event that directly and
materially adversely effects the value of the Intellectual Property Collateral."

     9.   Section 6.3(c) is hereby amended and replaced in its entirety, as
follows:

Business Day prior to such 15th date if the 15th date falls on a holiday,
Saturday or Sunday, and, if the aggregate outstanding amount of Revolving
Advances exceeds Five Million Dollars ($5,000,000), then also on the last day of
each calendar month that is a Business Day, Borrower shall deliver to Bank a
Borrowing Base Certificate signed by a Responsible Officer in substantially the

fiscal quarter during the term of this Agreement. a ratio of Quick Assets to
Current Liabilities (excluding deferred revenue) of at least 1.50 to 1.00."

          "6.10 Tangible Net Worth. Borrower shall maintain, as of the last day
                ------------------

of not less than Three Million Three Hundred Thousand Dollars ($3,300,000)."

     11.  The following new Section 6.12 is hereby added as follows:

          "6.12 Registration of Intellectual Property Rights. Borrower shall
                --------------------------------------------
register or cause to be registered (to the extent not already registered) with
the United States Patent and Trademark Office or the United States Copyright
Office, as applicable, those intellectual property rights listed on Exhibits A,
B and C to the Intellectual Property Security Agreement delivered to Bank by
Borrower in connection with this Agreement within thirty (30) days of the date
of this Agreement. Borrower shall register or cause to be registered with the
United States Patent and Trademark Office or the United States Copyright Office,
as applicable, those additional material patentable inventions, Trademarks, and
Copyrights relating to major software releases, and material additions,
revisions, enhancements, or improvements to existing Copyrights, developed or
acquired by Borrower from time to time in connection with any product prior to
the sale or licensing of such product to any third party, including without
limitation revisions or additions to the intellectual property rights listed on
such Exhibits A, B and C.

          (a) Borrower shall execute and deliver such additional instruments and
documents from time to time as Bank shall reasonably request to perfect Bank's
security interest in the Intellectual Property Collateral.

          (b) Borrower shall (i) protect, defend and maintain the validity and
enforceability of the Trademarks, Patents and Copyrights, (ii) use its best
efforts to detect infringements of the Trademarks, Patents and Copyrights and
promptly advise Bank in writing of material infringements detected and (iii) not
allow any Trademarks, Patents or Copyrights to be abandoned, forfeited or
dedicated to the public without the written consent of Bank, which shall not be
unreasonably withheld, unless Bank determines that reasonable business practices
suggest that abandonment is appropriate.

          (c) Bank shall have the right, but not the obligation, to take, at
Borrower's sole expense, any actions that Borrower is required under this
Section 6.8 to take but which Borrower fails to take, after thirty (30) days'
notice to Borrower. Borrower shall reimburse and indemnify Bank for all
reasonable costs and reasonable expenses incurred in the reasonable exercise of
its rights under this Section 6.12."

                                       5
<PAGE>

     12.  A new Section 7.12 is hereby added as follows:

          "7.12  Intellectual Property Agreements. Borrower shall not permit
                 --------------------------------
the inclusion in any material contract to which it becomes a party of any
provisions that would in any way prevent the creation of a security interest in
Borrower's rights and interests in any property included within the definition
of the Intellectual Property Collateral acquired under such contracts."

     13.  Section 8.2 is hereby amended and restated in its entirety as follows:

          "8.2   Covenant Default. If Borrower fails to perform any obligation
                 ----------------
under Section 6.7, 6.8, 6.9, 6.10 or 6.12 or violates any of the covenants
contained in Article 7 of this Agreement, or fails or neglects to perform, keep,
or observe any other material term, provision, condition, covenant, or agreement
contained in this Agreement, in any of the Loan Documents, or in any other
present or future agreement between Borrower and Bank and as to any default
under such other term, provision, condition, covenant or agreement that can be
cured, has failed to cure such default within thirty (30) days after Borrower
receives notice thereof or any officer of Borrower becomes aware thereof;
provided, however, that if the default cannot by its nature be cured within the
thirty (30) day period or cannot after diligent attempts by Borrower be cured
within such thirty (30) day period, and such default is likely to be cured
within a reasonable time, then Borrower shall have an additional reasonable
period (which shall not in any case exceed thirty (30) days) to attempt to cure
such default, and within such reasonable time period the failure to have cured
such default shall not be deemed an Event of Default (provided that no Advance
will be required to be made during such cure period);"

     14.  The following new Sections 9.2(f), 9.2(g) and 9.2(h) are hereby added
as follows:

          "(f) to modify, in its sole discretion, any intellectual property
security agreement entered into between Borrower and Bank without first
obtaining Borrower's approval of or signature to such modification by amending
Exhibit A, Exhibit B and Exhibit C, thereof, as appropriate, to include
reference to any right, title or interest in any Copyrights, Patents or
Trademarks acquired by Borrower after the execution hereof or to delete any
reference to any right, title or interest in any Copyrights, Patents or
Trademarks in which Borrower no longer has or claims any right, title or
interest; (g) to file, in its sole discretion, one or more financing or
continuation statements and amendments thereto, relative to any of the
Collateral without the signature of Borrower where permitted by law; and (h) to
transfer the Intellectual Property Collateral into the name of Bank or a third
party to the extent permitted under the California Uniform Commercial Code
provided Bank may exercise such power of attorney to sign the name of Borrower
on any of the documents described in Section 4.2 regardless of whether an Event
of Default has occurred;"

     15.  The following sentence is added at the end of Section 9.4 as follows:

          "Bank shall have a non-exclusive, royalty-free license to use the
Intellectual Property Collateral to the extent reasonably necessary to permit
Bank to exercise its rights and remedies upon the occurrence of an Event of
Default."

     16.  Exhibits C and E are hereby replaced in their entirety, with the
attached Exhibits C and E.

                                       6
<PAGE>

     17.  As a condition to the effectiveness of this Amendment, Borrower shall
pay all Bank Expenses (including reasonable attorneys' fees not to exceed
$2,500) incurred through the date of this Amendment, which fees and expenses
become nonrefundable and fully earned on the date hereof.

     18.  The obligation of Bank to make any further Advance pursuant to the
terms of the Agreement, as amended hereby, is subject to the condition precedent
that Bank shall have received, in form and substance satisfactory to Bank, the
following:

          a.   this Amendment, duly executed by the Borrower;

          b.   a certificate of secretary of the Borrower with respect to
incumbency and resolutions authorizing the execution and delivery of this
Amendment;

          c.   payment of the Bank Expenses then due as specified in Section 18
hereof;

          d.   an intellectual property security agreement with Exhibits A, B
and C in the form attached hereto as Exhibit F;

          e.   an audit of Borrower's Accounts;

          f.   a UCC-2 financing statement; and

          g.   such other documents, and completion of such other matters as
Bank may reasonably deem necessary or appropriate.

     19.  Unless otherwise defined, all capitalized terms in this Amendment
shall be as defined in the Agreement. Except as amended, the Agreement remains
in full force and effect.

     20.  Borrower represents and warrants that the Representations and
Warranties contained in the Agreement are true and correct as of the date of
this Amendment, and that no Event of Default has occurred and is continuing.

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

first date above written.

28, 1998, by and between SILICON VALLEY BANK ("Bank") and CROSSWORLDS SOFTWARE,
INC. ("Grantor").

                                   RECITALS
                                   --------

     A.   Bank has agreed to make certain advances of money and to extend
certain financial accommodation to Grantor (the "Loans") in the amounts and
manner set forth in that certain Loan and Security Agreement dated as of
December 10, 1996, as amended from time to time, including, without limitation,
the First Amendment to Loan and Security Agreement, dated as of September 29,
1997, and the Second Amendment to Loan and Security Agreement, dated as of
October 28, 1998 (as the same may be amended, modified or supplemented from time
to time, the "Loan Agreement"; capitalized terms used herein are used as defined
in the Loan Agreement). Bank is willing to make the Loans to Grantor, but only
upon the condition, among others, that Grantor shall grant to Bank a security
interest in certain Copyrights, Trademarks and Patents to secure the obligations
of Grantor under the Loan Agreement.

     B.   Pursuant to the terms of the Loan Agreement, Grantor has granted to
Bank a security interest in all of Grantor's right, title and interest, whether
presently existing or hereafter acquired, in, to and under all of the
Collateral.

     NOW, THEREFORE, for good and valuable consideration, receipt of which is
hereby acknowledged, and intending to be legally bound, as collateral security
for the prompt and complete payment when due of its obligations under the Loan
Agreement, Grantor hereby represents, warrants, covenants and agrees as follows:

                                   AGREEMENT
                                   ---------

     To secure its obligations under the Loan Agreement, Grantor grants and
pledges to Bank a security interest in all of Grantor's right, title and
interest in, to and under its Intellectual Property Collateral (including
without limitation those Copyrights, Patents and Trademarks listed on Schedules
A, B and C hereto), and including without limitation all proceeds thereof (such
as, by way of example but not by way of limitation, license royalties and
proceeds of infringement suits), the right to sue for past, present and future
infringements, all rights corresponding thereto throughout the world and all re-
issues, divisions continuations, renewals, extensions and continuations-in-part
thereof.

     This security interest is granted in conjunction with the security interest
granted to Bank under the Loan Agreement. The rights and remedies of Bank with
respect to the security interest granted hereby are in addition to those set
forth in the Loan Agreement and the other Loan Documents, and those which are
now or hereafter available to Bank as a matter of law or equity. Each right,
power and remedy of Bank provided for herein or in the Loan Agreement or any of
the Loan Documents, or now or hereafter existing at law or in equity shall be
cumulative and concurrent and shall be in addition to every right, power or
remedy provided for herein and the exercise by Bank of any one or more of the
rights, powers or remedies provided for in this Intellectual Property Security
Agreement, the Loan Agreement or any of the other Loan Documents, or now or
hereafter existing at law or in equity, shall not preclude the simultaneous or
later exercise by any person, including Bank, of any or all other rights, powers
or remedies.

     Notwithstanding the foregoing, the filing on the Patents, Copyrights and
Trademarks described on Schedules A, B and C hereto, is solely for the purpose
of perfecting a security interest in the accounts receivable with respect to
such Intellectual Property Collateral.

     Notwithstanding the foregoing, the term "Intellectual Property Collateral"
shall not include any general intangibles or contracts of Borrower (whether
owned or held as licensee or lessee, or otherwise) to the extent that (i) such
general intangibles are not assignable or capable of being encumbered as a
matter of law or under the terms of the license, lease or other agreement
applicable thereto (but solely to the extent that such restriction shall be
enforceable under applicable law) without the consent of the licensor or

                                       1
<PAGE>

lessor thereof or other applicable party thereto and (ii) such consent has not
been obtained; provided, however, that the foregoing grant of security interest
               --------  -------
shall extend to, and the term "Intellectual Property Collateral" shall include,
(A) any general intangible which is an Account or a proceed of, or otherwise
related to the enforcement or collection of, any Account or goods which are the
subject of any Account, and (B) any and all proceeds of any general intangibles
which are otherwise excluded to the extent that the assignment or encumbrance of
such proceeds is not so restricted, and (C) upon obtaining the consent of any
such licensor, lessor or other applicable party with respect to any such
otherwise excluded general intangibles, such general intangibles as well as any
and all proceeds thereof that might theretofore have been excluded from such
grant of a security interest and the term "Intellectual Property Collateral".

     IN WITNESS WHEREOF, the parties have cause this Intellectual Property
Security Agreement to be duly executed by its officers thereunto duly authorized
as of the first date written above.

     Notwithstanding any provision of that certain Fourth Restated Investors
Rights Agreement (the "Investor Rights Agreement"), dated as of January 7, 1999
and as amended as of the date hereof, among CrossWorlds Software, Inc. (the
"Company") and the other parties thereto, if the Company intends to effect its
initial public offering ("IPO"), each of you ("Investor") shall have a right of
first refusal to purchase in the IPO (excluding any over-allotment option) an
amount of securities which the Company proposes to sell in the IPO equal to 100%
of the amount sufficient to maintain such Investor's proportionate beneficial
ownership interest in the Company (determined without reference to any over-
allotment option) attributable only to the Series E Preferred Stock of the
Company (or Common Stock issued upon conversion of the Series E Preferred Stock,
or a combination thereof) held by such Investor ("Investor Series E Preferred
Stock"), in accordance with  the provisions of this letter, or such other
procedure as the Company shall agree upon in writing with the holders of a
majority of all outstanding shares of Investor Series E Preferred Stock (or
Common Stock issuable upon conversion of the Investor Series E Preferred, or a
combination thereof).

     The Company shall provide (or cause the underwriters to provide) each of
the Investors with a copy of the preliminary prospectus included in the
registration statement for such IPO at least 10 days prior to the anticipated
effective date of such IPO, and shall at such time provide (or cause the
underwriters to provide) each Investor with reasonable instructions for
contacting the underwriters of the IPO to arrange for the purchase by each such
Investor in the IPO of the securities which such Investor is entitled to
purchase pursuant to this letter.  For purposes of determining the pro rata
interest of each Investor, each security holder of the Company shall be treated
as owning that number of shares of Common Stock into which any outstanding
convertible securities may be converted and for which any outstanding options
may be exercised.  Any Investor desiring to participate in the IPO pursuant to
this letter shall follow such reasonable instructions and shall inform the
underwriters of its intention to exercise its rights hereunder within 5 days
after receiving such preliminary prospectus.

     To the extent that the Investors have not so offered to purchase all of the
shares available to them for purchase pursuant to this letter within 5 days of
the anticipated effective date of the registration statement for the IPO, the
Company or the underwriters shall inform those Investors who have so offered to
participate in the IPO pursuant to this letter of such number of available
shares not so offered to be purchased (the "Excess Shares"), and each of the
Investors who has offered to participate in the IPO  shall have the right to
purchase the Excess Shares on a pro rata basis (based upon the number of shares
each such Investor was originally entitled to purchase pursuant to this );
provided, however, that the maximum number of Excess Shares which any Investor
shall be entitled to purchase shall be an amount which results in such Investor
participating in the IPO on a pro rata basis to the extent necessary to
<PAGE>

maintain 100% of such Investor's proportionate beneficial interest in the
Company as a Series E Preferred Stock holder (determined as provided above).

     The foregoing right may be transferred to any transferee of at least 50,000
shares of Series E Preferred Stock or to any person who is an Amerindo
Affiliate, as such term is defined below.  The foregoing right  shall be subject
to applicable SEC and NASD rules and regulations and shall be subject to cut
back to the extent deemed necessary by the managing underwriter in the IPO as
being necessary to the success of the offering for reasons which it shall set
forth in writing.

     In addition, each Investor agrees that during the one hundred eighty (180)
day period following the effective date of the IPO, it shall not sell, offer to
sell, or otherwise transfer or dispose of the shares of the Company acquired
though exercise of the rights granted to such Investor pursuant to this letter.
To enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the shares held by each Investor (and the shares of
every other person subject to the foregoing restriction) until the end of such
period.  Each Investor agrees to execute the form of such market stand-off
agreement as may be reasonably requested by the underwriters.

     It is hereby further agreed that Amerindo Investment Advisors Inc. and each
of its affiliated companies under common control with it, as well as each of its
and their respective employees and each of its and their clients with assets
under management by any of them shall be deemed to be "affiliates" of each other
and "affiliated" with each other for all purposes of this letter agreement.
Each such person is herein referred to as an "Amerindo Affiliate."

     Finally, it is also understood and agreed that notwithstanding anything
contained in the Stock Purchase Agreement among the Investors, the Company and
the other parties thereto, or Investor Rights Agreements to the contrary or in
any future amendment thereto to which all Amerindo Affiliates then holding
Series E Preferred Stock (including shares of Common Stock issued on conversion
thereof) have not expressly consented in writing),  the market stand-off
agreement provided for in Section 1.11 of such Investor Rights Agreement shall
not be deemed to extend to, and no Amerindo Affiliate shall be required to enter
into any such arrangement purporting to extend to, any securities of the Company
acquired by any Amerindo Affiliate in the open market following the IPO, or to
any securities of the Company acquired by any Amerindo  Affiliate in the IPO,
other than shares acquired by an Amerindo Affiliate pursuant to the IPO right
provided for in this letter.

                           STOCK PURCHASE AGREEMENT

     THIS STOCK PURCHASE AGREEMENT is made as of the ____ day of ________ 2000,
by and between CrossWorlds Software, Inc., a Delaware corporation (the
"Company") and Electronic Data Systems Corporation (the "Investor").

     WHEREAS, the Investor has indicated a desire to purchase shares of Common
Stock, $0.001 par value (the "Common Stock") from the Company at the price per
share set forth in Section 1.2 below.

     WHEREAS, the Company has indicated a desire to sell shares of Common Stock
to the Investor at the price per share set forth in Section 1.2 below.

     WHEREAS, the Company and the Investor have agreed that this Agreement shall
constitute the entire understanding and agreement between the parties with
regard to the subject matter hereof.

     NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

     1.  Purchase and Sale of Stock.
         --------------------------

          1.1  Sale and Issuance of Stock.  Subject to the terms and conditions
               --------------------------
     of this Agreement, the Company agrees to sell to the Investor and the
     Investor agrees to purchase from the Company at the price per share set
     forth in Section 1.2 below such number of shares of the Company's Common
     Stock (the "Stock") as is equal to the lesser of:  (I) the difference
     obtained by subtracting (A) the quotient obtained by dividing (x) the
     number of shares of issued and outstanding Common Stock of the Company
     immediately prior to the closing of the IPO (as defined below), giving
     effect to the conversion into Common Stock of outstanding shares of
     preferred stock and giving effect to the issuance of all shares to be
     issued in the IPO (including any over-allotment option shares) and giving
     effect to the issuance of any other shares of the Company's capital stock
     to be issued in private placements that are closed concurrently with the
     closing of the IPO (as defined below) (with the number in this subpart (x)
     referred to as the "Numerator Shares"), by (y) 0.98, minus (B) the
     Numerator Shares; or (II) $10,000,000 million of shares of Common Stock at
     the price per share set forth in Section 1.2 below.

          1.2  The Closing.  The purchase and sale of the Stock shall be held at
               -----------
     the Company's offices concurrently with the closing of the Company's
     initial public offering (the "IPO") assuming that each of the conditions
     set forth in Sections 4 and 5 have been satisfied or waived (the
     "Closing").  At the Closing, the Company will deliver the Stock to the
     Investor against payment of the purchase price therefor by check payable to
     the order of the Company or by wire transfer.  The per share purchase price
     for the Stock shall be equal to the per share price paid by the public for
     the Company's Common Stock in the IPO, less any underwriter discounts and
     commissions, as reflected on the cover

                                      -1-

     page of the final prospectus for such offering (as corrected for
     typographical errors, if necessary, thereafter).

represents and warrants to the Investor that, except as disclosed to the

     carry on its business as now conducted.

          2.2  Authorization.  All corporate action on the part of the Company,
               -------------

     Agreement will be a valid and binding obligation of the Company,
     enforceable against the Company in accordance with its terms, subject to
     laws of general application relating to bankruptcy, insolvency and the
     relief of debtors and by general principles of equity.

          2.3  Valid Issuance of Stock.  The Stock, when issued, sold and
               -----------------------
     delivered in accordance with the terms hereof for the consideration
     expressed, will be duly and validly issued, fully paid and nonassessable,
     free and clear of any claims, liens, encumbrances, security interests,
     options, charges or restrictions whatsoever, and, based in part upon the
     representations of the Investor in this Agreement, will be issued in
     compliance with all applicable federal and state securities laws.

          2.4  Litigation.  Except as set forth in the Company's registration
               ----------
     statement prepared in connection with the IPO, as filed with the Securities
     and Exchange Commission ("SEC") and amended from time to time (the
     "Registration Statement"), there are no actions, proceedings or
     investigations pending or, to the best of Company's knowledge, any basis
     therefor or threat thereof, against or affecting the Company, that, either
     in any case or in the aggregate, would result in any material adverse
     change in the business, financial condition, or results of operations of
     the Company.

          2.5  Properties.  To the Company's knowledge (but without having
               ----------
     conducted any special investigation), the Company has (i) good and
     marketable title to its properties and assets and has good title to all its
     leasehold interests, and (ii) sufficient title, license and/or ownership of
     all patents, trademarks, service marks, trade names, copyrights, trade
     secrets, information, proprietary rights and processes necessary for its
     business as now conducted on the date hereof.

          2.6  Compliance with Other Documents.  The execution and delivery of
               -------------------------------
     this Agreement, consummation of the transactions contemplated hereby, and
     compliance with

                                      -2-
<PAGE>

     the terms and provisions hereof will not conflict with or result in a
     breach of the terms and conditions of, or constitute a default under the
     Restated Certificate or Bylaws of the Company or of any contract or
     agreement to which the Company is now a party, except where such conflict,
     breach or default of any such contract or agreement, either individually or
     in the aggregate, would not have a material adverse effect either on the
     Company's business, financial condition or results of operations or on the
     transactions contemplated by this Agreement.

          2.7  Financial Statements.  The Company's audited balance sheet at
               --------------------
     December 31, 1999, and the related statements of operations and statements
     of cash flows for the period then ended (collectively, the "Financial
     Statements"): (I) are in accordance with the books and records of the
     Company, (II) present fairly the financial condition of the Company at such
     date and the results of its operations for the period therein specified,
     and (III) have been prepared in accordance with generally accepted
     accounting principles applied on a consistent basis.  The Company has no
     material liabilities or obligations which are not shown or provided for in
     the Financial Statements, except liabilities or obligations after December
     31, 1999 in the ordinary course of business which, individually or in the
     aggregate, would not be reasonably likely to have a material adverse effect
     upon the business, operations or financial condition of the Company.

     3.  Representations and Warranties of the Investor.  The Investor hereby
         ----------------------------------------------
represents and warrants that:

          3.1  Authorization.  This Agreement constitutes the valid and legally
               -------------
     binding obligation of the Investor, enforceable in accordance with its
     terms, subject to laws of general application relating to bankruptcy,
     insolvency and the relief of debtors and by general principles of equity.

          3.2  Investigation.  The Investor acknowledges that it has had an
               -------------
     opportunity to discuss the business, affairs and current prospects of the
     Company with the Company's president.  The Investor further acknowledges
     having had access to information about the Company that it has requested or
     considers necessary for purposes of purchasing the Stock.

          3.3  Accredited Investor.  The Investor is an "accredited investor" as
               -------------------
     such term is defined in Regulation D adopted by the SEC.

               ---------------------------------
     the Investor in reliance upon the Investor's representation to the Company,
     which by the Investor's execution of this Agreement the Investor hereby
     confirms, that the Stock will be acquired for investment for the Investor's
     own account, not as a nominee or agent, and not with a view to the resale
     or distribution of any part thereof, and that the Investor has no present
     intention of selling, granting any participation in, or otherwise
     distributing the same.

                                      -3-

     4.  Conditions to the Investor's Obligation at Closing.  The obligation of

the Investor to purchase the Stock at the Closing is subject to the fulfillment
to the Investor's satisfaction on or prior to the Closing of the following
conditions:

     Act") and qualification requirements of all applicable state securities
     laws.

          4.3  Authorizations.  All authorizations, approvals or permits, if

     any, of any governmental authority or regulatory body or other persons that
     are required for the Company to obtain on its own behalf in connection with

               (a) Prior to the first anniversary of the Closing, the Investor
          shall not, directly or indirectly, Transfer or offer to Transfer any
          shares of the Stock other than to affiliates who agree to be bound by
          the terms of this Agreement, unless the Company consents to such
          Transfer and the transferee agrees to be bound by this Agreement.  Any
          such Transfer must comply with all applicable laws, and the Company
          may require an opinion of counsel reasonably satisfactory to it as to
          such compliance.  The restrictions set forth above are referred to as
          the "Transfer Restrictions."

                                      -5-
<PAGE>

               (b) In order to enforce the Transfer Restrictions, the Company
          may impose stop-transfer instructions with respect to the Stock until
          the end of the restricted period.

               (c) As used in this Agreement, the term "Transfer" shall mean any
          sale, transfer, assignment, hypothecation, encumbrance or other
          disposition, whether voluntary or involuntary, of shares of the Stock.
          In the case of a hypothecation, the Transfer shall be deemed to occur
          both at the time of the initial pledge and at any pledgee's sale or a
          sale by any secured creditor or a retention by the secured creditor of
          the pledged shares of the Stock in complete or partial satisfaction of
          the indebtedness for which the shares of the Stock are security.

               (d) After the first anniversary of the Closing, the Investor may
          Transfer shares of the Stock without the transferee agreeing to be
          bound by this Agreement and without the consent of the Company,
          provided such Transfer complies with applicable federal and state
          securities laws.

          6.2  Market Stand-Off.  In addition to the Transfer Restrictions
               ----------------
     (which shall in no way be limited by the following), in connection with any
     underwritten public offering by the Company of its equity securities
     pursuant to an effective registration statement filed under the Securities
     Act, the Investor shall not Transfer or offer to Transfer any shares of the
     Stock without the prior written consent of the Company and its
     underwriters.  Such restriction (the "Market Stand-Off") shall be in effect
     for such period of time from and after the effective date of the final
     prospectus for the offering as may be requested by the Company or such
     underwriters; provided, however, that (i) such Market Stand-Off shall not
     exceed one hundred eighty (180) days, and (ii) the Investor shall be
     subject to the Market Stand-Off only if the officers and directors of the
     Company are also subject to similar restrictions.  In order to enforce the
     Market Stand-Off, the Company may impose stop-transfer instructions with
     respect to the Stock until the end of the applicable stand-off period.

          6.3  Voting Agreements.  The following provision will be applicable at
               -----------------
     any time the Investor owns or controls in excess of 9.5% of the Voting
     Securities (as defined below) during the first five (5) years after the
     Closing: In the event that the Board of Directors of the Company approves a
     sale of substantially all of the assets or capital stock of the Company or
     a merger in which the Company would not be the surviving corporation, the
     Investor agrees to vote all shares of Voting Securities owned by it with
     respect to such sale of substantially all of the assets or capital stock or
     merger in the same proportion as the votes cast by all other stockholders
     of the Company entitled to vote on such matter (other than the Investor) at
     such time as such matter is presented for a vote of the stockholders of the
     Company.  The Investor, as a holder of Voting Securities, shall be present,
     in person or by proxy, at all meetings of stockholders of the Company so
     that all shares of Voting Securities beneficially owned by it may be
     counted for the purpose of determining the presence of a quorum at such
     meetings.  For purposes of this Agreement, (i) the term "Voting Securities"
     shall refer to all securities of the Company entitled to vote

                                      -6-
<PAGE>

     generally for the election of directors, and (ii) the term "beneficial
     ownership" shall have the meaning set forth in Rule 13d-3 under the
     Securities Exchange Act of 1934, as amended (the "Exchange Act").

<PAGE>

          (g) The term "Registrable Securities" means Common Stock issued to the
                        ----------------------

          1.2   Piggyback Registration Rights.
                -----------------------------

                (a) Registration Rights. At any time after January 31, 2001, if
                    -------------------
the Company proposes to register any of its stock or other securities under the
Act in connection with the public offering of such securities solely for cash
(other than a registration relating solely to the sale of securities to
participants in a Company stock plan, a registration effected pursuant to Rule
145 under the Act, or a registration on any form which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of the Registrable Securities) the
Company shall, at such time, promptly give each Holder written notice of such
registration. Upon the written request of each Holder given within fifteen (15)
days after mailing of such notice by the Company in accordance with Section 7 of
the Purchase Agreement, the Company shall, subject to the provisions of
paragraph (b) below, cause to be registered under the Act all of the Registrable
Securities that each such Holder has requested to be registered.

                (b) Underwriting. If the registration of which the Company gives
                    ------------
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as part of the written notice given pursuant
to Section 1.2(a). In such event, the right of any Holder to registration
pursuant to this Section 1.2 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company and the other holders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by the Company.
Notwithstanding any other provision of this Section 1.2, if the Company and the
managing underwriter determine that marketing factors require a limitation of
the number of shares to be underwritten, the managing underwriter may limit or
exclude entirely the Registrable Securities to be included in such registration.
The Company shall so advise all Holders distributing their securities through
such underwriting, and the number of shares of Registrable Securities and other
securities that may be

                                      -2-
<PAGE>

included in the registration and underwriting on behalf of persons other than
the Company shall be allocated among all Holders and such other holders in
proportion, as nearly as practicable, to the respective amounts of Registrable
Securities and other securities entitled to registration rights held by such
Holders and other holders at the time of filing the registration statement. To
facilitate the allocation of shares in accordance with the above provisions, the
Company may round the number of shares allocated to any Holder or other holder
to the nearest 100 shares.

          1.3  Furnish Information.  It shall be a condition precedent to the
               -------------------
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

          1.4  Expenses of Registration.  The Company shall bear and pay all
               ------------------------
expenses incurred in connection with any registration, filing (including keeping
such filings effective) or qualification of Registrable Securities with respect
to the registrations pursuant to this Agreement, including (without limitation)
all registration, filing, and qualification fees, printers and accounting fees
relating or apportionable thereto and the fees and disbursements of counsel for
the Company and no more than one counsel for all the selling Holders, but
excluding underwriting discounts and commissions relating to Registrable
Securities.

          1.5  No Delay of Registration.  No Holder shall have any right to
               ------------------------
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 1.

          1.6  Indemnification.  In the event any Registrable Securities are
               ---------------
included in a registration statement under this Section 1:

               (a) To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Act or the 1934 Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the Act,
the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "Violation"): (i) any untrue statement or alleged untrue
                 ---------
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any state securities law or
any rule or regulation promulgated under the Act, the 1934 Act or any state
securities law; and the Company will pay to each such Holder, underwriter or
controlling person any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability, or action, as such expenses are incurred; provided, however, that

                                      -3-
<PAGE>

the indemnity agreement contained in this subsection 1.6(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability, or action
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable to any
indemnitee for any such loss, claim, damage, liability, or action to the extent
that it arises out of or is based upon a Violation which occurs in reliance upon
and in conformity with written information furnished by such indemnitee.

          (b) To the extent permitted by law, each Holder will indemnify and
hold harmless the Company, each of its directors, each of its officers who has
signed the registration statement, each person, if any, who controls the Company
within the meaning of the Act, any underwriter, any other Holder selling
securities in such registration statement and any controlling person of any such
underwriter or other Holder, severally but not jointly, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereto) arise out of or are based upon any Violation, in each case
to the extent (and only to the extent) that such Violation occurs in reliance
upon and in conformity with written information furnished by such Holder; and
each such Holder will pay any legal or other expenses reasonably incurred by any
person intended to be indemnified pursuant to this subsection 1.6(b), in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 1.6(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be unreasonably
withheld; provided that in no event shall any indemnity by any Holder under this
subsection 1.6(b) exceed the gross proceeds from the offering received by such
Holder.

          (c) Promptly after receipt by an indemnified party under this Section
1.6 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 1.6, deliver to the
indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with one counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding.  The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action shall not relieve such indemnifying party of any liability to the
indemnified party under this Section 1.6 unless the failure to deliver notice is
materially prejudicial to its ability to defend such action.  Any omission to so
deliver written notice to the indemnifying party will not relieve it of any
liability that it may have to any indemnified party otherwise than under this
Section 1.6.

                                      -4-
<PAGE>

          (d) If the indemnification provided for in this Section 1.6 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, liability, claim, damage, or expense referred to therein,
then the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amount paid or payable by such indemnified
party as a result of such loss, liability, claim, damage, or expense in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that resulted in such loss, liability, claim,
damage, or expense as well as any other relevant equitable considerations;
provided that in no event shall any Holder be required to contribute under this
subsection 1.6(d) an aggregate amount in excess of the gross proceeds from the
offering received by such Holder less any amounts paid by the Holder pursuant to
subsection 1.6(b).  The relative fault of the indemnifying party and of the
indemnified party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

          (e) Notwithstanding the foregoing, to the extent that the provisions
on indemnification and contribution contained in the underwriting agreement
entered into in connection with the underwritten public offering are in conflict
with the foregoing provisions, the provisions in the underwriting agreement
shall control.

          (f) The obligations of the Company and Holders under this Section 1.6
shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1, and otherwise.

          1.7  Reports under Securities Exchange Act of 1934.  With a view to
               ---------------------------------------------
making available to the Holders the benefits of Rule 144 promulgated under the
Act and any other rule or regulation of the SEC that may at any time permit a
Holder to sell securities of the Company to the public without registration, the
Company agrees to:

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

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

          (c) furnish to any Holder, so long as the Holder owns any Registrable
Securities, forthwith upon request (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144 (at any time
after ninety (90) days after the effective date of the first registration
statement filed by the Company), the Act and the 1934 Act (at any time after it
has become subject to such reporting requirements), (ii) a copy of the most
recent annual or quarterly report of the Company and such other reports and
documents so filed by the Company, and (iii) such other information as may be
reasonably requested in availing any

                                      -5-
<PAGE>

Holder of any rule or regulation of the SEC which permits the selling of any
such securities without registration.

          1.8  Assignment of Registration Rights.  The rights to cause the
               ---------------------------------
Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities who, after such assignment or transfer, holds at
least one hundred thousand (100,000) shares of Registrable Securities (subject
to appropriate adjustment for stock splits, dividends, combinations and other
recapitalizations), provided:  (a) the Company is, within a reasonable time
before such transfer, furnished with written notice of the name and address of
such transferee or assignee and the securities with respect to which such
registration rights are being assigned; (b) such transferee or assignee agrees
in writing to be bound by and subject to the terms and conditions of this
Agreement, including without limitation the provisions of Section 1.9 below; and
(c) such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Act.  For the purposes of determining the
number of shares of Registrable Securities held by a transferee or assignee of a
holder of Registrable Securities, Affiliated Persons shall be aggregated
together, provided that all assignees and transferees who would not qualify
individually for assignment of registration rights shall designate in writing to
the Company from time to time a single attorney-in-fact on behalf of the entire
group of Affiliated Persons for the purpose of exercising any rights, receiving
notices or taking any action under this Section 1.

          1.9  "Market Stand-Off" Agreement.  The Investor shall be bound by the
               ----------------------------
transfer restrictions and market standoff provisions set forth in the Purchase
Agreement to the extent, but only to the extent, set forth in the Purchase
Agreement.  In addition:

               (a) Each Holder other than the Investor hereby agrees that,
during the period of duration specified by the Company and an underwriter of
common stock or other securities of the Company, following the effective date of
a registration statement of the Company filed under the Act, it shall not, to
the extent requested by the Company and such underwriter, directly or indirectly
sell, offer to sell, contract to sell (including, without limitation, any short
sale), grant any option to purchase or otherwise transfer or dispose of (other
than to donees who agree to be similarly bound) any securities of the Company
held by it as of the effective date except common stock included in such
registration; provided, however, that:

                   (i) all officers and directors of the Company enter into
similar agreements; and

                   (ii) such market stand-off time period shall not exceed one
hundred eighty (180) days without the consent of the affected Holder; and

               (b) Each Holder other than the Investor agrees to provide to the
other Underwriters of any public offering such further agreement as such
Underwriter may require in connection with this market stand-off agreement. In
order to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each

                                      -6-
<PAGE>

Holder (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such period.

          1.10  Termination of Registration Rights.  The right of any Holder
                ----------------------------------
to inclusion in any registration pursuant to Section 1.2 shall terminate upon
such date as, in the opinion of counsel to the Company,  a public trading market
shall exist for the Company's Common Stock and all shares of Registrable
Securities beneficially owned or subject to Rule 144 aggregation by such Holder
may immediately be sold under Rule 144 (without regard to Rule 144(k)) during
any 90-day period and such Holder holds less than one percent (1%) of the
outstanding capital stock of the Company.

     2.  Securities Law Compliance.
         -------------------------

          2.1  Restrictions on Transferability.  The Registrable Securities
               -------------------------------
and any other securities issued with respect of the Registrable Securities upon
any stock split, stock dividend, recapitalization, merger, consolidation, or
similar event, shall not be sold, assigned, transferred or pledged except upon
the conditions specified in the Purchase Agreement and this Agreement, which
conditions are intended to ensure compliance with the provisions of the Act, or
otherwise in compliance with the Act.  In any sale, transfer, assignment or
pledge of any such shares prior to the first anniversary of the Closing (as
defined in the Purchase Agreement) other than in a public offering, the Investor
will cause any proposed purchaser, assignee, transferee, or pledgee of such
shares held by the Investor to agree to take and hold such securities subject to
the provisions and upon the conditions specified in the Purchase Agreement and
this Agreement, unless otherwise consented to by the Company.

          2.2  Further Limitations on Disposition.  Without in any way
               ----------------------------------
limiting the above, the Investor further agrees not to make any disposition of
all or any portion of the Registrable Securities unless and until the transferee
has agreed in writing for the benefit of the Company to be bound by Sections 1.9
of this Agreement and (to the extent required by applicable securities law, in
the opinion of counsel to the Company) has agreed to be bound by these Sections
2.1 and 2.2; provided, however, that the foregoing shall not apply if:

               (a) There is then in effect a Registration Statement under the
Act covering such proposed disposition and such disposition is made in
accordance with such Registration Statement; or

               (b) (i) The Investor shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii)
until such time as the proposed disposition may be made under Rule 144(k) under
the 1934 Act, if reasonably requested by the Company, the Investor shall have
furnished the Company with an opinion of counsel, reasonably satisfactory to the
Company, that such disposition will not require registration of such shares
under the Act; or

               (c) The proposed disposition is made under Rule 144(k).

                                      -7-
<PAGE>

          2.3  Notwithstanding anything to the contrary contained herein, the
shares of stock acquired by the Investor from the Company pursuant to the
Purchase Agreement (and any other securities issued with respect to such
securities upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event) may be sold, assigned, transferred or pledged by
Investor to any person and such person shall not be required to take and hold
such securities subject to the Purchase Agreement, this Agreement or any of the
provisions hereof or thereof, so long as the transaction is at least one year
after the Closing (as defined in the Purchase Agreement), complies with
applicable federal and state securities laws, and Investor is not transferring
to such person the registration rights set forth in Section 1 hereof.

     3.  Miscellaneous.  Section 7 of the Purchase Agreement is hereby
         -------------
incorporated by reference as though restated in full herein and applied to this
Agreement.

                           STOCK PURCHASE AGREEMENT

     THIS STOCK PURCHASE AGREEMENT is made as of the ____ day of ________ 2000,
by and between CrossWorlds Software, Inc., a Delaware corporation (the
"Company") and  The Dow Chemical Company (the "Investor").

     WHEREAS, the Investor has indicated a desire to purchase shares of Common
Stock, $0.001 par value (the "Common Stock") from the Company at the price per
share set forth in Section 1.2 below.

     WHEREAS, the Company has indicated a desire to sell shares of Common Stock
to the Investor at the price per share set forth in Section 1.2 below.

     WHEREAS, the Company and the Investor have agreed that this Agreement shall
constitute the entire understanding and agreement between the parties with
regard to the subject matter hereof.

     NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

     1.  Purchase and Sale of Stock.
         --------------------------

         1.1  Sale and Issuance of Stock.  Subject to the terms and conditions
              --------------------------
     of this Agreement, the Company agrees to sell to the Investor and the
     Investor agrees to purchase from the Company at the price per share set
     forth in Section 1.2 below such number of shares of the Company's Common
     Stock (the "Stock") as is equal to $2 million of shares of Common Stock at
     the price per share set forth in Section 1.2 below.

         1.2  The Closing.  The purchase and sale of the Stock shall be held at
              -----------
     the Company's offices concurrently with the closing of the Company's
     initial public offering (the "IPO") assuming that each of the conditions
     set forth in Sections 4 and 5 have been satisfied or waived (the
     "Closing").  At the Closing, the Company will deliver the Stock to the
     Investor against payment of the purchase price therefor by check payable to
     the order of the Company or by wire transfer.  The per share purchase price
     for the Stock shall be equal to the per share price paid by the public for
     the Company's Common Stock in the IPO, less any underwriter discounts and
     commissions, as reflected on the cover page of the final prospectus for
     such offering (as corrected for typographical errors, if necessary,
     thereafter).

     2.  Representations and Warranties of the Company.  The Company hereby
         ---------------------------------------------
represents and warrants to the Investor that, except as disclosed to the
Investor in a separate letter dated as of the date of this Agreement:

          2.1  Organization and Good Standing.  The Company is a corporation
               ------------------------------
     duly organized, validly existing and in good standing under the laws of the
     State of Delaware and has all requisite corporate power and authority to
     carry on its business as now conducted.

          2.2  Authorization.  All corporate action on the part of the Company,
               -------------
     its officers, directors and stockholders necessary for the authorization,
     execution and delivery of this Agreement, the performance of all
     obligations of the Company hereunder, and the authorization, issuance and
     delivery of the Stock has been taken or will be taken at the Company's next
     Board meeting prior to the Closing.  Upon such authorization, this
     Agreement will be a valid and binding obligation of the Company,
     enforceable against the Company in accordance with its terms, subject to
     laws of general application relating to bankruptcy, insolvency and the
     relief of debtors and by general principles of equity.

          2.3  Valid Issuance of Stock.  The Stock, when issued, sold and
               -----------------------
     delivered in accordance with the terms hereof for the consideration
     expressed, will be duly and validly issued, fully paid and nonassessable,
     free and clear of any claims, liens, encumbrances, security interests,
     options, charges or restrictions whatsoever, and, based in part upon the
     representations of the Investor in this Agreement, will be issued in
     compliance with all applicable federal and state securities laws.
<PAGE>

          2.4  Litigation.  Except as set forth in the Company's registration
               ----------
     statement prepared in connection with the IPO, as filed with the Securities
     and Exchange Commission ("SEC") and amended from time to time (the
     "Registration Statement"), there are no actions, proceedings or
     investigations pending or, to the best of Company's knowledge, any basis
     therefor or threat thereof, against or affecting the Company, that, either
     in any case or in the aggregate, would result in any material adverse
     change in the business, financial condition, or results of operations of
     the Company.

          2.5  Properties.  To the Company's knowledge (but without having
               ----------
     conducted any special investigation), the Company has (i) good and
     marketable title to its properties and assets and has good title to all its
     leasehold interests, and (ii) sufficient title, license and/or ownership of
     all patents, trademarks, service marks, trade names, copyrights, trade
     secrets, information, proprietary rights and processes necessary for its
     business as now conducted on the date hereof.

          2.6  Compliance with Other Documents.  The execution and delivery of
               -------------------------------
     this Agreement, consummation of the transactions contemplated hereby, and
     compliance with the terms and provisions hereof will not conflict with or
     result in a breach of the terms and conditions of, or constitute a default
     under the Restated Certificate or Bylaws of the Company or of any contract
     or agreement to which the Company is now a party, except where such
     conflict, breach or default of any such contract or agreement, either
     individually or in the aggregate, would not have a material adverse effect
     either on the Company's business, financial condition or results of
     operations or on the transactions contemplated by this Agreement.

          2.7  Financial Statements.  The Company's audited balance sheet at
               --------------------
     December 31, 1999, and the related statements of operations and statements
     of cash flows for the period then ended (collectively, the "Financial
     Statements"): (I) are in accordance with the books and records of the
     Company, (II) present fairly the financial condition of the Company at such
     date and the results of its operations for the period therein specified,
     and (III) have been prepared in accordance with generally accepted
     accounting principles applied on a consistent basis.  The Company has no
     material liabilities or obligations which are not shown or provided for in
     the Financial Statements, except liabilities or obligations after December
     31, 1999 in the ordinary course of business which, individually or in the
     aggregate, would not be reasonably likely to have a material adverse effect
     upon the business, operations or financial condition of the Company.

     3.  Representations and Warranties of the Investor.  The Investor hereby
         ----------------------------------------------
represents and warrants that:

          3.1  Authorization.  This Agreement constitutes the valid and legally
               -------------

     terms, subject to laws of general application relating to bankruptcy,
     insolvency and the relief of debtors and by general principles of equity.

     considers necessary for purposes of purchasing the Stock.

          3.3  Accredited Investor.  The Investor is an "accredited investor" as
               -------------------
     such term is defined in Regulation D adopted by the SEC.

          3.4  Purchase Entirely for Own Account.  This Agreement is made with
               ---------------------------------
     the Investor in reliance upon the Investor's representation to the Company,
     which by the Investor's execution of this Agreement the Investor hereby
     confirms, that the Stock will be acquired for investment for the Investor's
     own account, not as a nominee or agent, and not with a view to the resale
     or distribution of any part thereof, and that the Investor has no present
     intention of selling, granting any participation in, or otherwise
     distributing the same.

     4.  Conditions to the Investor's Obligation at Closing.  The obligation of
         --------------------------------------------------
the Investor to purchase the Stock at the Closing is subject to the fulfillment
to the Investor's satisfaction on or prior to the Closing of the following

              ------------------------------
     warranties made by the Company in Section 2 hereof shall be true and
     correct when made, and shall be true and correct as of the Closing with the
     same force and effect as if they had been made on and as of such date,

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

         6.1  Agreement Not to Transfer.
              -------------------------

              (a)     Prior to the first anniversary of the Closing, the
         Investor shall not, directly or indirectly, Transfer or offer to
         Transfer any shares of the Stock other than to affiliates who agree to
         be bound by the terms of this Agreement, unless the Company consents to
         such Transfer and the transferee agrees to be bound by this Agreement.
         Any such Transfer must comply with all applicable laws, and the Company
         may require an opinion of counsel reasonably satisfactory to it as to
         such compliance. The restrictions set forth above are referred to as
         the "Transfer Restrictions."

              (b)     In order to enforce the Transfer Restrictions, the Company
         may impose stop-transfer instructions with respect to the Stock until
         the end of the restricted period.

              (c)     As used in this Agreement, the term "Transfer" shall mean
         any sale, transfer, assignment, hypothecation, encumbrance or other
         disposition, whether voluntary or involuntary, of shares of the Stock.
         In the case of a hypothecation, the Transfer shall be deemed to occur
         both at the time of the initial pledge and at any pledgee's sale or a
         sale by any secured creditor or a retention by the secured creditor of
         the pledged shares of the Stock in complete or partial satisfaction of
         the indebtedness for which the shares of the Stock are security.

              (d)     After the first anniversary of the Closing, the Investor
         may Transfer shares of the Stock without the transferee agreeing to be
         bound by this Agreement and without the consent of the Company,
         provided such Transfer complies with applicable federal and state
         securities laws.

          6.2  Market Stand-Off.  In addition to the Transfer Restrictions
               ----------------
(which shall in no way be limited by the following), in connection with any
underwritten public offering by the Company of its equity securities pursuant to
an effective registration statement filed under the Securities Act, the Investor
shall not Transfer or offer to Transfer any shares of the Stock without the
prior written consent of the Company and its underwriters. Such restriction (the
"Market Stand-Off") shall be in effect for such period of time from and after
the effective date of the final prospectus for the offering as may be requested
by the Company or such underwriters; provided, however, that (i) such Market
Stand-Off shall not exceed one hundred eighty (180) days, and (ii) the Investor
shall be subject to the Market Stand-Off only if the officers and directors of
the Company are also subject to similar restrictions. In order to enforce the
Market Stand-Off, the Company may impose stop-transfer instructions with respect
to the Stock until the end of the applicable stand-off period.

          6.3  Voting Agreements.  The following provision will be applicable at
               -----------------
any time the Investor owns or controls in excess of 9.5% of the Voting
Securities (as defined below) during the first five (5) years after the Closing:
In the event that the Board of Directors of the Company approves a sale of
substantially all of the assets or capital stock of the Company or a merger in
which the Company would not be the surviving corporation, the Investor agrees to
vote all shares of Voting Securities owned by it with respect to such sale of
substantially all of the assets or capital stock or merger in the same
proportion as the votes cast

                                      -4-
<PAGE>

by all other stockholders of the Company entitled to vote on such matter (other
than the Investor) at such time as such matter is presented for a vote of the
stockholders of the Company. The Investor, as a holder of Voting Securities,
shall be present, in person or by proxy, at all meetings of stockholders of the
Company so that all shares of Voting Securities beneficially owned by it may be
counted for the purpose of determining the presence of a quorum at such
meetings. For purposes of this Agreement, (i) the term "Voting Securities" shall
refer to all securities of the Company entitled to vote generally for the
election of directors, and (ii) the term "beneficial ownership" shall have the
meaning set forth in Rule 13d-3 under the Securities Exchange Act of 1934, as
amended (the "Exchange Act").

          6.4  Investor Rights Agreement.  Concurrently with the execution of

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

              (a)     Registration Rights. At any time after January 31, 2001,
                      -------------------
if the Company proposes to register any of its stock or other securities under
the Act in connection with the public offering of such securities solely for
cash (other than a registration relating solely to the sale of securities to
participants in a Company stock plan, a registration effected pursuant to Rule
145 under the Act, or a registration on any form which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of the Registrable Securities) the
Company shall, at such time, promptly give each Holder written notice of such
registration. Upon the written request of each Holder given within fifteen (15)
days after mailing of such notice by the Company in accordance with Section 7,
the Company shall, subject to the provisions of paragraph (b) below, cause to be
registered under the Act of the Purchase Agreement all of the Registrable
Securities that each such Holder has requested to be registered.

         (b)   Underwriting. If the registration of which the Company gives
               ------------
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as part of the written notice given pursuant
to Section 1.2(a). In such event, the right of any Holder to registration
pursuant to this Section 1.2 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein. All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company and the other holders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by the Company.
Notwithstanding any other provision of this Section 1.2, if the Company and the
managing underwriter determine that marketing factors require a limitation of
the number of shares to be underwritten, the managing underwriter may limit or
exclude entirely the Registrable Securities to be included in such registration.
The Company shall so advise all Holders distributing their securities through
such underwriting, and the number of shares of Registrable Securities and other
securities that may be included in the registration and underwriting on behalf
of persons other than the Company shall be allocated among all Holders and such
other holders in proportion, as nearly as practicable, to the respective amounts
of Registrable Securities and other securities entitled to registration rights
held by such Holders and other holders at the time of filing the registration
statement. To facilitate the allocation of shares in accordance with the above
provisions, the Company may round the number of shares allocated to any Holder
or other holder to the nearest 100 shares.

         1.3  Furnish Information.  It shall be a condition precedent to the
              -------------------
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

         1.4  Expenses of Registration.  The Company shall bear and pay all
              ------------------------
expenses incurred in connection with any registration, filing (including keeping
such filings effective) or qualification of Registrable Securities with respect
to the registrations pursuant to this Agreement, including (without limitation)
all registration, filing, and qualification fees, printers and accounting fees
relating or apportionable thereto and the fees and disbursements of counsel for
the Company and no more than one counsel for all the selling Holders, but
excluding underwriting discounts and commissions relating to Registrable
Securities.

         1.5  No Delay of Registration.  No Holder shall have any right to
              ------------------------
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 1.

         1.6  Indemnification.  In the event any Registrable Securities are
              ---------------
included in a registration statement under this Section 1:


                                      -2-
<PAGE>

              (a)     To the extent permitted by law, the Company will indemnify
and hold harmless each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Act or the 1934 Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the Act,
the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "Violation"): (i) any untrue statement or alleged untrue
                 ---------
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any state securities law or
any rule or regulation promulgated under the Act, the 1934 Act or any state
securities law; and the Company will pay to each such Holder, underwriter or
controlling person any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability, or action, as such expenses are incurred; provided, however, that the
indemnity agreement contained in this subsection 1.6(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability, or action
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable to any
indemnitee for any such loss, claim, damage, liability, or action to the extent
that it arises out of or is based upon a Violation which occurs in reliance upon
and in conformity with written information furnished by such indemnitee.

              (b)     To the extent permitted by law, each Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
has signed the registration statement, each person, if any, who controls the
Company within the meaning of the Act, any underwriter, any other Holder selling
securities in such registration statement and any controlling person of any such
underwriter or other Holder, severally but not jointly, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereto) arise out of or are based upon any Violation, in each case
to the extent (and only to the extent) that such Violation occurs in reliance
upon and in conformity with written information furnished by such Holder; and
each such Holder will pay any legal or other expenses reasonably incurred by any
person intended to be indemnified pursuant to this subsection 1.6(b), in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 1.6(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be unreasonably
withheld; provided that in no event shall any indemnity by any Holder under this
subsection 1.6(b) exceed the gross proceeds from the offering received by such
Holder.

              (c)     Promptly after receipt by an indemnified party under this
Section 1.6 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.6, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with one counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action shall not relieve such indemnifying party of any liability to the
indemnified party under this Section 1.6 unless the failure to deliver notice is
materially prejudicial to its ability to defend such action. Any omission to so
deliver written notice to the indemnifying party will not relieve it of any
liability that it may have to any indemnified party otherwise than under this
Section 1.6.

              (d)     If the indemnification provided for in this Section 1.6 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder,
<PAGE>

shall contribute to the amount paid or payable by such indemnified party as a
result of such loss, liability, claim, damage, or expense in such proportion as
is appropriate to reflect the relative fault of the indemnifying party on the
one hand and of the indemnified party on the other in connection with the
statements or omissions that resulted in such loss, liability, claim, damage, or
expense as well as any other relevant equitable considerations; provided that in
no event shall any Holder be required to contribute under this subsection 1.6(d)
an aggregate amount in excess of the gross proceeds from the offering received
by such Holder less any amounts paid by the Holder pursuant to subsection
1.6(b). The relative fault of the indemnifying party and of the indemnified
party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the indemnifying party or by
the indemnified party and the parties' relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement or omission.

              (e)     Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

              (f)     The obligations of the Company and Holders under this
Section 1.6 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 1, and otherwise.

         1.7  Reports under Securities Exchange Act of 1934.  With a view to
              ---------------------------------------------
making available to the Holders the benefits of Rule 144 promulgated under the
Act and any other rule or regulation of the SEC that may at any time permit a
Holder to sell securities of the Company to the public without registration, the
Company agrees to:

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

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

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

         1.8  Assignment of Registration Rights.  The rights to cause the
              ---------------------------------
Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities who, after such assignment or transfer, holds at
least one hundred thousand (100,000) shares of Registrable Securities (subject
to appropriate adjustment for stock splits, dividends, combinations and other
recapitalizations), provided:  (a) the Company is, within a reasonable time
before such transfer, furnished with written notice of the name and address of
such transferee or assignee and the securities with respect to which such
registration rights are being assigned; (b) such transferee or assignee agrees
in writing to be bound by and subject to the terms and conditions of this
Agreement, including without limitation the provisions of Section 1.9 below; and
(c) such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Act.  For the purposes of determining the
number of shares of Registrable Securities held by a transferee or assignee of a
holder of Registrable Securities, Affiliated Persons shall be aggregated
together, provided that all assignees and transferees who would not qualify
individually for assignment of registration rights shall designate in writing to
the Company from time to time


                                      -4-
<PAGE>

a single attorney-in-fact on behalf of the entire group of Affiliated Persons
for the purpose of exercising any rights, receiving notices or taking any action
under this Section 1.

         1.9  "Market Stand-Off" Agreement. The Investor shall be bound by
              ----------------------------
the transfer restrictions and market standoff provisions set forth in the
Purchase Agreement to the extent, but only to the extent, set forth in the
Purchase Agreement.  In addition:

              (a)     Each Holder other than the Investor hereby agrees that,
during the period of duration specified by the Company and an underwriter of
common stock or other securities of the Company, following the effective date of
a registration statement of the Company filed under the Act, it shall not, to
the extent requested by the Company and such underwriter, directly or indirectly
sell, offer to sell, contract to sell (including, without limitation, any short
sale), grant any option to purchase or otherwise transfer or dispose of (other
than to donees who agree to be similarly bound) any securities of the Company
held by it as of the effective date except common stock included in such
registration; provided, however, that:

                      (i)    all officers and directors of the Company enter
into similar agreements; and

                      (ii)   such market stand-off time period shall not exceed
one hundred eighty (180) days without the consent of the affected Holder; and

              (b)     Each Holder other than the Investor agrees to provide to
the other Underwriters of any public offering such further agreement as such
Underwriter may require in connection with this market stand-off agreement. In
order to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

         1.10  Termination of Registration Rights.  The right of any Holder
               ----------------------------------
to inclusion in any registration pursuant to Section 1.2 shall terminate upon
such date as, in the opinion of counsel to the Company,  a public trading market
shall exist for the Company's Common Stock and all shares of Registrable
Securities beneficially owned or subject to Rule 144 aggregation by such Holder
may immediately be sold under Rule 144 (without regard to Rule 144(k)) during
any 90-day period and such Holder holds less than one percent (1%) of the
outstanding capital stock of the Company.

     2.  Securities Law Compliance.
         -------------------------

         2.1   Restrictions on Transferability. The Registrable Securities and
               -------------------------------
any other securities issued with respect of the Registrable Securities upon any
stock split, stock dividend, recapitalization, merger, consolidation, or similar
event, shall not be sold, assigned, transferred or pledged except upon the
conditions specified in the Purchase Agreement and this Agreement, which
conditions are intended to ensure compliance with the provisions of the Act, or
otherwise in compliance with the Act.  In any sale, transfer, assignment or
pledge of any such shares prior to the first anniversary of the Closing (as
defined in the Purchase Agreement) other than in a public offering, the Investor
will cause any proposed purchaser, assignee, transferee, or pledgee of such
shares held by the Investor to agree to take and hold such securities subject to
the provisions and upon the conditions specified in the Purchase Agreement and
this Agreement, unless otherwise consented to by the Company.

         2.2   Further Limitations on Disposition.  Without in any way
               ----------------------------------
limiting the above, the Investor further agrees not to make any disposition of
all or any portion of the Registrable Securities unless and until the transferee
has agreed in writing for the benefit of the Company to be bound by Sections 1.9
of this Agreement and (to the extent required by applicable securities law, in
the opinion of counsel to the Company) has agreed to be bound by these Sections
2.1 and 2.2; provided, however, that the foregoing shall not apply if:

               (a)  There is then in effect a Registration Statement under the
Act covering such proposed disposition and such disposition is made in
accordance with such Registration Statement; or

                                      -5-
<PAGE>

              (b)     (i) The Investor shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii)
until such time as the proposed disposition may be made under Rule 144(k) under
the 1934 Act, if reasonably requested by the Company, the Investor shall have
furnished the Company with an opinion of counsel, reasonably satisfactory to the
Company, that such disposition will not require registration of such shares
under the Act; or

              (c)     The proposed disposition is made under Rule 144(k).

         2.3  Notwithstanding anything to the contrary contained herein, the
shares of stock acquired by the Investor from the Company pursuant to the
Purchase Agreement (and any other securities issued with respect to such
securities upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event) may be sold, assigned, transferred or pledged by
Investor to any person and such person shall not be required to take and hold
such securities subject to the Purchase Agreement, this Agreement or any of the
provisions hereof or thereof, so long as the transaction is at least one year
after the Closing (as defined in the Purchase Agreement), complies with
applicable federal and state securities laws, and Investor is not transferring
to such person the registration rights set forth in Section 1 hereof.

     3.  Miscellaneous.  Section 7 of the Purchase Agreement is hereby
         -------------
incorporated by reference as though restated in full herein and applied to this
Agreement.

                            STOCK PURCHASE AGREEMENT

     THIS STOCK PURCHASE AGREEMENT is made as of the ____ day of ________ 2000,
by and between CrossWorlds Software, Inc., a Delaware corporation (the
"Company") and  Delphi Automotive (the "Investor").

     WHEREAS, the Investor has indicated a desire to purchase shares of Common
Stock, $0.001 par value (the "Common Stock") from the Company at the price per
share set forth in Section 1.2 below.

     WHEREAS, the Company has indicated a desire to sell shares of Common Stock
to the Investor at the price per share set forth in Section 1.2 below.

     WHEREAS, the Company and the Investor have agreed that this Agreement shall
constitute the entire understanding and agreement between the parties with
regard to the subject matter hereof.

     NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

     1.  Purchase and Sale of Stock.
         --------------------------

         1.1  Sale and Issuance of Stock.  Subject to the terms and conditions
              --------------------------
     of this Agreement, the Company agrees to sell to the Investor and the
     Investor agrees to purchase from the Company at the price per share set
     forth in Section 1.2 below such number of shares of the Company's Common
     Stock (the "Stock") as is equal to $2 million of shares of Common Stock at
     the price per share set forth in Section 1.2 below.

         1.2  The Closing.  The purchase and sale of the Stock shall be held at
              -----------
     the Company's offices concurrently with the closing of the Company's
     initial public offering (the "IPO") assuming that each of the conditions
     set forth in Sections 4 and 5 have been satisfied or waived (the
     "Closing").  At the Closing, the Company will deliver the Stock to the
     Investor against payment of the purchase price therefor by check payable to
     the order of the Company or by wire transfer.  The per share purchase price
     for the Stock shall be equal to the per share price paid by the public for
     the Company's Common Stock in the IPO, less any underwriter discounts and
     commissions, as reflected on the cover page of the final prospectus for
     such offering (as corrected for typographical errors, if necessary,
     thereafter).

     2.  Representations and Warranties of the Company.  The Company hereby
         ---------------------------------------------
represents and warrants to the Investor that, except as disclosed to the
Investor in a separate letter dated as of the date of this Agreement:

         2.1  Organization and Good Standing.  The Company is a corporation
              ------------------------------
     duly organized, validly existing and in good standing under the laws of the
     State of Delaware and has all requisite corporate power and authority to
     carry on its business as now conducted.

         2.2  Authorization.  All corporate action on the part of the Company,
              -------------
     its officers, directors and stockholders necessary for the authorization,
     execution and delivery of this Agreement, the performance of all
     obligations of the Company hereunder, and the authorization, issuance and
     delivery of the Stock has been taken or will be taken at the Company's next
     Board meeting prior to the Closing.  Upon such authorization, this
     Agreement will be a valid and binding obligation of the Company,
     enforceable against the Company in accordance with its terms, subject to
     laws of general application relating to bankruptcy, insolvency and the
     relief of debtors and by general principles of equity.

         2.3  Valid Issuance of Stock.  The Stock, when issued, sold and
              -----------------------
     delivered in accordance with the terms hereof for the consideration
     expressed, will be duly and validly issued, fully paid and nonassessable,
     free and clear of any claims, liens, encumbrances, security interests,
     options, charges or restrictions whatsoever, and, based in part upon the
     representations of the Investor in this Agreement, will be issued in
     compliance with all applicable federal and state securities laws.
<PAGE>

         2.4  Litigation.  Except as set forth in the Company's registration
              ----------
     statement prepared in connection with the IPO, as filed with the Securities
     and Exchange Commission ("SEC") and amended from time to time (the
     "Registration Statement"), there are no actions, proceedings or
     investigations pending or, to the best of Company's knowledge, any basis
     therefor or threat thereof, against or affecting the Company, that, either
     in any case or in the aggregate, would result in any material adverse
     change in the business, financial condition, or results of operations of
     the Company.

         2.5  Properties.  To the Company's knowledge (but without having
              ----------
     conducted any special investigation), the Company has (i) good and
     marketable title to its properties and assets and has good title to all its
     leasehold interests, and (ii) sufficient title, license and/or ownership of
     all patents, trademarks, service marks, trade names, copyrights, trade
     secrets, information, proprietary rights and processes necessary for its
     business as now conducted on the date hereof.

         2.6  Compliance with Other Documents.  The execution and delivery of
              -------------------------------
     this Agreement, consummation of the transactions contemplated hereby, and
     compliance with the terms and provisions hereof will not conflict with or
     result in a breach of the terms and conditions of, or constitute a default
     under the Restated Certificate or Bylaws of the Company or of any contract
     or agreement to which the Company is now a party, except where such
     conflict, breach or default of any such contract or agreement, either
     individually or in the aggregate, would not have a material adverse effect
     either on the Company's business, financial condition or results of
     operations or on the transactions contemplated by this Agreement.

         2.7  Financial Statements.  The Company's audited balance sheet at
              --------------------
     December 31, 1999, and the related statements of operations and statements
     of cash flows for the period then ended (collectively, the "Financial
     Statements"): (I) are in accordance with the books and records of the
     Company, (II) present fairly the financial condition of the Company at such
     date and the results of its operations for the period therein specified,
     and (III) have been prepared in accordance with generally accepted
     accounting principles applied on a consistent basis.  The Company has no
     material liabilities or obligations which are not shown or provided for in
     the Financial Statements, except liabilities or obligations after December
     31, 1999 in the ordinary course of business which, individually or in the
     aggregate, would not be reasonably likely to have a material adverse effect
     upon the business, operations or financial condition of the Company.

     3.  Representations and Warranties of the Investor.  The Investor hereby
         ----------------------------------------------
represents and warrants that:

         3.1  Authorization.  This Agreement constitutes the valid and legally
              -------------

     which by the Investor's execution of this Agreement the Investor hereby
     confirms, that the Stock will be acquired for investment for the Investor's
     own account, not as a nominee or agent, and not with a view to the resale
     or distribution of any part thereof, and that the Investor has no present
     intention of selling, granting any participation in, or otherwise
     distributing the same.

     6.  Covenants of the Company and the Investor.
         -----------------------------------------

         6.1  Agreement Not to Transfer.
              -------------------------

              (a) Prior to the first anniversary of the Closing, the Investor
         shall not, directly or indirectly, Transfer or offer to Transfer any
         shares of the Stock other than to affiliates who agree to be bound by
         the terms of this Agreement, unless the Company consents to such
         Transfer and the transferee agrees to be bound by this Agreement. Any
         such Transfer must comply with all applicable laws, and the Company may
         require an opinion of counsel reasonably satisfactory to it as to such
         compliance. The restrictions set forth above are referred to as the
         "Transfer Restrictions."

              (b) In order to enforce the Transfer Restrictions, the Company
         may impose stop-transfer instructions with respect to the Stock until
         the end of the restricted period.

              (c) As used in this Agreement, the term "Transfer" shall mean any
         sale, transfer, assignment, hypothecation, encumbrance or other
         disposition, whether voluntary or involuntary, of shares of the Stock.
         In the case of a hypothecation, the Transfer shall be deemed to occur
         both at the time of the initial pledge and at any pledgee's sale or a
         sale by any secured creditor or a retention by the secured creditor of
         the pledged shares of the Stock in complete or partial satisfaction of
         the indebtedness for which the shares of the Stock are security.

              (d) After the first anniversary of the Closing, the Investor may
         Transfer shares of the Stock without the transferee agreeing to be
         bound by this Agreement and without the consent of the Company,
         provided such Transfer complies with applicable federal and state
         securities laws.

         6.2  Market Stand-Off.  In addition to the Transfer Restrictions
              ----------------
     (which shall in no way be limited by the following), in connection with any
     underwritten public offering by the Company of its equity securities
     pursuant to an effective registration statement filed under the Securities
     Act, the Investor shall not Transfer or offer to Transfer any shares of the
     Stock without the prior written consent of the Company and its
     underwriters.  Such restriction (the "Market Stand-Off") shall be in effect
     for such period of time from and after the effective date of the final
     prospectus for the offering as may be requested by the Company or such
     underwriters; provided, however, that (i) such Market Stand-Off shall not
     exceed one hundred eighty (180) days, and (ii) the Investor shall be
     subject to the Market Stand-Off only if the officers and directors of the
     Company are also subject to similar restrictions.  In order to enforce the
     Market Stand-Off, the Company may impose stop-transfer instructions with
     respect to the Stock until the end of the applicable stand-off period.

         6.3  Voting Agreements.  The following provision will be applicable at
              -----------------
     any time the Investor owns or controls in excess of 9.5% of the Voting
     Securities (as defined below) during the first five (5) years after the
     Closing: In the event that the Board of Directors of the Company approves a
     sale of substantially all of the assets or capital stock of the Company or
     a merger in which the Company would not be the surviving corporation, the
     Investor agrees to vote all shares of Voting Securities owned by it with
     respect to such sale of substantially all of the assets or capital stock or
     merger in the same proportion as the votes cast

                                      -4-
<PAGE>

     by all other stockholders of the Company entitled to vote on such matter
     (other than the Investor) at such time as such matter is presented for a
     vote of the stockholders of the Company. The Investor, as a holder of
     Voting Securities, shall be present, in person or by proxy, at all meetings
     of stockholders of the Company so that all shares of Voting Securities
     beneficially owned by it may be counted for the purpose of determining the
     presence of a quorum at such meetings. For purposes of this Agreement, (i)
     the term "Voting Securities" shall refer to all securities of the Company
     entitled to vote generally for the election of directors, and (ii) the term
     "beneficial ownership" shall have the meaning set forth in Rule 13d-3 under
     the Securities Exchange Act of 1934, as amended (the "Exchange Act").

         6.4  Investor Rights Agreement.  Concurrently with the execution of
              -------------------------
     this Agreement, the parties shall enter into the Investor Rights Agreement
     attached hereto as Exhibit A.

     agreements set forth in Section 6 to the same extent the Stock is at such

         7.7  Legal Fees.  In the event of any action at law, suit in equity or
              ----------
     arbitration proceeding in relation to this Agreement or the Stock or any

     reasonable sum for the attorneys' fees and expenses incurred by such
     prevailing party.

         7.8  Expenses; No Liability.  Irrespective of whether the Closing is
              ----------------------
     effected, the Company and the Investor shall each pay their own costs and
     expenses incurred with respect to the negotiation, execution, delivery and
     performance of this Agreement.  The parties agree that if the Closing does
     not occur due to reasons including the failure of the conditions set forth
     in Section 4.2 or Section 5.2, this Agreement shall terminate without
     liability on the part of any party to the other for any resulting damages,
     claims or other liabilities.

         7.9  Titles and Subtitles.  The titles of the paragraphs and
              --------------------

         7.10 Counterparts.  This Agreement may be executed in counterparts,

     constitute one instrument.

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

         7.12 Confidentiality.  The parties hereto agree that, except with the
              ---------------
     prior written permission of the other party, each shall at all times keep

     confidential information, knowledge, or data concerning or relating to the
     business or financial affairs of such other party to which said party has
     been or shall become privy by reason of (i) this Agreement, (ii)
     discussions or negotiations relating to this Agreement, or (iii) the
     performance of obligations hereunder.  The parties agree that for the
     purposes of this Section 7.12 confidential information shall not include

                                    RECITALS

pursuant to the Purchase Agreement, the Company desires to grant certain
registration rights to the Investor as set forth herein.

     NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

     1.  Registration Rights.  The Company covenants and agrees as follows:
         -------------------

partnership, trust, incorporated or unincorporated association, joint venture,

political subdivision thereof) or other entity of any kind, and shall include
any successor (by merger or otherwise) of such entity.

              (f) The terms "register", "registered" and "registration" refer
                             --------    ----------       ------------
to a registration effected by preparing and filing a registration statement or
similar document in compliance with the Act, and the declaration or ordering of
effectiveness of such registration statement or document.

              (g) The term "Registrable Securities" means Common Stock issued
                            ----------------------
to the Investor pursuant to the Purchase Agreement, and any Common Stock of the
Company issued as (or issuable upon the conversion or exercise of any warrant,
right or other security which is issued as) a dividend or other distribution

         1.2  Piggyback Registration Rights.
              -----------------------------

              (a) Registration Rights.  At any time after January 31, 2001, if
                  -------------------
the Company proposes to register any of its stock or other securities under the
Act in connection with the public offering of such securities solely for cash
(other than a registration relating solely to the sale of securities to
participants in a Company stock plan, a registration effected pursuant to Rule
145 under the Act, or a registration on any form which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of the Registrable Securities) the
Company shall, at such time, promptly give each Holder written notice of such
registration. Upon the written request of each Holder given within fifteen (15)
days after mailing of such notice by the Company in accordance with Section 7 of
the Purchase Agreement, the Company shall, subject to the provisions of
paragraph (b) below, cause to be registered under the Act all of the Registrable
Securities that each such Holder has requested to be registered.

              (b) Underwriting.  If the registration of which the Company gives
                  ------------
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as part of the written notice given pursuant
to Section 1.2(a).  In such event, the right of any Holder to registration
pursuant to this Section 1.2 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of Registrable Securities
in the underwriting to the extent provided herein.  All Holders proposing to
distribute their securities through such underwriting shall (together with the
Company and the other holders distributing their securities through such
underwriting) enter into an underwriting agreement in customary form with the
managing underwriter selected for such underwriting by the Company.
Notwithstanding any other provision of this Section 1.2, if the Company and the
managing underwriter determine that marketing factors require a limitation of
the number of shares to be underwritten, the managing underwriter may limit or
exclude entirely the Registrable Securities to be included in such registration.
The Company shall so advise all Holders distributing their securities through
such underwriting, and the number of shares of Registrable Securities and other
securities that may be included in the registration and underwriting on behalf
of persons other than the Company shall be allocated among all Holders and such
other holders in proportion, as nearly as practicable, to the respective amounts
of Registrable Securities and other securities entitled to registration rights
held by such Holders and other holders at the time of filing the registration
statement.  To facilitate the allocation of shares in accordance with the above
provisions, the Company may round the number of shares allocated to any Holder
or other holder to the nearest 100 shares.

         1.3  Furnish Information.  It shall be a condition precedent to the
              -------------------
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

         1.4  Expenses of Registration.  The Company shall bear and pay all
              ------------------------
expenses incurred in connection with any registration, filing (including keeping
such filings effective) or qualification of Registrable Securities with respect
to the registrations pursuant to this Agreement, including (without limitation)
all registration, filing, and qualification fees, printers and accounting fees
relating or apportionable thereto and the fees and disbursements of counsel for
the Company and no more than one counsel for all the selling Holders, but
excluding underwriting discounts and commissions relating to Registrable
Securities.

         1.5  No Delay of Registration.  No Holder shall have any right to
              ------------------------
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect to
the interpretation or implementation of this Section 1.

         1.6  Indemnification.  In the event any Registrable Securities are
               --------------
included in a registration statement under this Section 1:

                                      -2-
<PAGE>

              (a) To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Act or the 1934 Act, against any losses, claims, damages, or
liabilities (joint or several) to which they may become subject under the Act,
the 1934 Act or other federal or state law, insofar as such losses, claims,
damages, or liabilities (or actions in respect thereof) arise out of or are
based upon any of the following statements, omissions or violations
(collectively a "Violation"):  (i) any untrue statement or alleged untrue
                 ---------
statement of a material fact contained in such registration statement, including
any preliminary prospectus or final prospectus contained therein or any
amendments or supplements thereto, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any state securities law or
any rule or regulation promulgated under the Act, the 1934 Act or any state
securities law; and the Company will pay to each such Holder, underwriter or
controlling person any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such loss, claim, damage,
liability, or action, as such expenses are incurred; provided, however, that the
indemnity agreement contained in this subsection 1.6(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability, or action
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable to any
indemnitee for any such loss, claim, damage, liability, or action to the extent
that it arises out of or is based upon a Violation which occurs in reliance upon
and in conformity with written information furnished by such indemnitee.

              (b) To the extent permitted by law, each Holder will indemnify and
hold harmless the Company, each of its directors, each of its officers who has
signed the registration statement, each person, if any, who controls the Company
within the meaning of the Act, any underwriter, any other Holder selling
securities in such registration statement and any controlling person of any such
underwriter or other Holder, severally but not jointly, against any losses,
claims, damages, or liabilities (joint or several) to which any of the foregoing
persons may become subject, under the Act, the 1934 Act or other federal or
state law, insofar as such losses, claims, damages, or liabilities (or actions
in respect thereto) arise out of or are based upon any Violation, in each case
to the extent (and only to the extent) that such Violation occurs in reliance
upon and in conformity with written information furnished by such Holder; and
each such Holder will pay any legal or other expenses reasonably incurred by any
person intended to be indemnified pursuant to this subsection 1.6(b), in
connection with investigating or defending any such loss, claim, damage,
liability, or action; provided, however, that the indemnity agreement contained
in this subsection 1.6(b) shall not apply to amounts paid in settlement of any
such loss, claim, damage, liability or action if such settlement is effected
without the consent of the Holder, which consent shall not be unreasonably
withheld; provided that in no event shall any indemnity by any Holder under this
subsection 1.6(b) exceed the gross proceeds from the offering received by such
Holder.

              (c) Promptly after receipt by an indemnified party under this
Section 1.6 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.6, deliver to
the indemnifying party a written notice of the commencement thereof and the
indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with one counsel mutually
satisfactory to the parties; provided, however, that an indemnified party
(together with all other indemnified parties which may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action shall not relieve such indemnifying party of any liability to the
indemnified party under this Section 1.6 unless the failure to deliver notice is
materially prejudicial to its ability to defend such action. Any omission to so
deliver written notice to the indemnifying party will not relieve it of any
liability that it may have to any indemnified party otherwise than under this
Section 1.6.

              (d) If the indemnification provided for in this Section 1.6 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage, or expense referred to
therein, then the indemnifying party, in lieu of indemnifying such indemnified
party hereunder,

                                      -3-
<PAGE>

shall contribute to the amount paid or payable by such indemnified party as a
result of such loss, liability, claim, damage, or expense in such proportion as
is appropriate to reflect the relative fault of the indemnifying party on the
one hand and of the indemnified party on the other in connection with the
statements or omissions that resulted in such loss, liability, claim, damage, or
expense as well as any other relevant equitable considerations; provided that in
no event shall any Holder be required to contribute under this subsection 1.6(d)
an aggregate amount in excess of the gross proceeds from the offering received
by such Holder less any amounts paid by the Holder pursuant to subsection
1.6(b). The relative fault of the indemnifying party and of the indemnified
party shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the indemnifying party or by
the indemnified party and the parties' relative intent, knowledge, access to
information, and opportunity to correct or prevent such statement or omission.

              (e) Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering are
in conflict with the foregoing provisions, the provisions in the underwriting
agreement shall control.

              (f) The obligations of the Company and Holders under this Section
1.6 shall survive the completion of any offering of Registrable Securities in a
registration statement under this Section 1, and otherwise.

         1.7  Reports under Securities Exchange Act of 1934.  With a view to
              ---------------------------------------------
making available to the Holders the benefits of Rule 144 promulgated under the
Act and any other rule or regulation of the SEC that may at any time permit a
Holder to sell securities of the Company to the public without registration, the
Company agrees to:

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

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

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

         1.8  Assignment of Registration Rights.  The rights to cause the
              ---------------------------------
Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by a Holder to a transferee or
assignee of such securities who, after such assignment or transfer, holds at
least one hundred thousand (100,000) shares of Registrable Securities (subject
to appropriate adjustment for stock splits, dividends, combinations and other
recapitalizations), provided:  (a) the Company is, within a reasonable time
before such transfer, furnished with written notice of the name and address of
such transferee or assignee and the securities with respect to which such
registration rights are being assigned; (b) such transferee or assignee agrees
in writing to be bound by and subject to the terms and conditions of this
Agreement, including without limitation the provisions of Section 1.9 below; and
(c) such assignment shall be effective only if immediately following such
transfer the further disposition of such securities by the transferee or
assignee is restricted under the Act.  For the purposes of determining the
number of shares of Registrable Securities held by a transferee or assignee of a
holder of Registrable Securities, Affiliated Persons shall be aggregated
together, provided that all assignees and transferees who would not qualify
individually for assignment of registration rights shall designate in writing to
the Company from time to time

                                      -4-
<PAGE>

a single attorney-in-fact on behalf of the entire group of Affiliated Persons
for the purpose of exercising any rights, receiving notices or taking any action
under this Section 1.

         1.9  "Market Stand-Off" Agreement. The Investor shall be bound by
              ----------------------------
the transfer restrictions and market standoff provisions set forth in the
Purchase Agreement to the extent, but only to the extent, set forth in the
Purchase Agreement.  In addition:

              (a) Each Holder other than the Investor hereby agrees that, during
the period of duration specified by the Company and an underwriter of common
stock or other securities of the Company, following the effective date of a
registration statement of the Company filed under the Act, it shall not, to the
extent requested by the Company and such underwriter, directly or indirectly
sell, offer to sell, contract to sell (including, without limitation, any short
sale), grant any option to purchase or otherwise transfer or dispose of (other
than to donees who agree to be similarly bound) any securities of the Company
held by it as of the effective date except common stock included in such
registration; provided, however, that:

                  (i) all officers and directors of the Company enter into
similar agreements; and

                  (ii) such market stand-off time period shall not exceed one
hundred eighty (180) days without the consent of the affected Holder; and

              (b) Each Holder other than the Investor agrees to provide to the
other Underwriters of any public offering such further agreement as such
Underwriter may require in connection with this market stand-off agreement. In
order to enforce the foregoing covenant, the Company may impose stop-transfer
instructions with respect to the Registrable Securities of each Holder (and the
shares or securities of every other person subject to the foregoing restriction)
until the end of such period.

         1.10 Termination of Registration Rights.  The right of any Holder
              ----------------------------------
to inclusion in any registration pursuant to Section 1.2 shall terminate upon
such date as, in the opinion of counsel to the Company,  a public trading market
shall exist for the Company's Common Stock and all shares of Registrable
Securities beneficially owned or subject to Rule 144 aggregation by such Holder
may immediately be sold under Rule 144 (without regard to Rule 144(k)) during
any 90-day period and such Holder holds less than one percent (1%) of the
outstanding capital stock of the Company.

     2.  Securities Law Compliance.
         -------------------------

         2.1  Restrictions on Transferability. The Registrable Securities and
              -------------------------------
any other securities issued with respect of the Registrable Securities upon any
stock split, stock dividend, recapitalization, merger, consolidation, or similar
event, shall not be sold, assigned, transferred or pledged except upon the
conditions specified in the Purchase Agreement and this Agreement, which
conditions are intended to ensure compliance with the provisions of the Act, or
otherwise in compliance with the Act.  In any sale, transfer, assignment or
pledge of any such shares prior to the first anniversary of the Closing (as
defined in the Purchase Agreement) other than in a public offering, the Investor
will cause any proposed purchaser, assignee, transferee, or pledgee of such
shares held by the Investor to agree to take and hold such securities subject to
the provisions and upon the conditions specified in the Purchase Agreement and
this Agreement, unless otherwise consented to by the Company.

         2.2  Further Limitations on Disposition.  Without in any way
              ----------------------------------
limiting the above, the Investor further agrees not to make any disposition of
all or any portion of the Registrable Securities unless and until the transferee
has agreed in writing for the benefit of the Company to be bound by Sections 1.9
of this Agreement and (to the extent required by applicable securities law, in
the opinion of counsel to the Company) has agreed to be bound by these Sections
2.1 and 2.2; provided, however, that the foregoing shall not apply if:

              (a) There is then in effect a Registration Statement under the Act
covering such proposed disposition and such disposition is made in accordance
with such Registration Statement; or

                                      -5-
<PAGE>

              (b) (i) The Investor shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii)
until such time as the proposed disposition may be made under Rule 144(k) under
the 1934 Act, if reasonably requested by the Company, the Investor shall have
furnished the Company with an opinion of counsel, reasonably satisfactory to the
Company, that such disposition will not require registration of such shares
under the Act; or

              (c) The proposed disposition is made under Rule 144(k).

         2.3  Notwithstanding anything to the contrary contained herein, the
shares of stock acquired by the Investor from the Company pursuant to the
Purchase Agreement (and any other securities issued with respect to such
securities upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event) may be sold, assigned, transferred or pledged by
Investor to any person and such person shall not be required to take and hold
such securities subject to the Purchase Agreement, this Agreement or any of the
provisions hereof or thereof, so long as the transaction is at least one year
after the Closing (as defined in the Purchase Agreement), complies with
applicable federal and state securities laws, and Investor is not transferring
to such person the registration rights set forth in Section 1 hereof.

     3.  Miscellaneous.  Section 7 of the Purchase Agreement is hereby
         -------------
incorporated by reference as though restated in full herein and applied to this
Agreement.

                                      -6-

     IN WITNESS WHEREOF, the parties have executed this Investor Rights
Agreement as of the date first above written.

Gentlemen:

     This letter confirms certain disclosures by CrossWorlds Software, Inc. (the
"Company") to you under Section 2 of the Stock Purchase Agreement dated as of
the above date.  In particular, the Company's representations in Section 2 are
true and correct as of today's date, except as follows:

     2.5.  Comdisco and Silicon Valley Bank have liens on the Company's assets.

     Additionally, the Company agrees with you that, except for the maximum
number of shares being purchased under the Stock Purchase Agreement and except
as otherwise provided further below, the material terms of the Stock Purchase
Agreement and Investor Rights Agreement attached thereto will be no less
favorable to you than the terms applicable under agreements with other investors
(including investors that may enter into such agreements after the date hereof,
if any) that are purchasing shares of the Company's capital stock in private
placements that are intended to close concurrently with the closing of the IPO.
The Company will not enter into any amendment or supplement to the terms of any
of such other agreements without first providing the Investor with reasonable
notice thereof and the opportunity, if Investor so elects, to so amend or
supplement the Stock Purchase Agreement and Investor Rights Agreement attached
thereto.

     In addition to the foregoing, however, you acknowledge that if the SEC
takes the position that one or more of the Company's stock purchase agreements
with investors (including you) cannot be closed as a private placement of
securities concurrently with the closing of the IPO, the Company may terminate
any or all of such agreements as the Company sees fit in the Company's sole
discretion, without regard to the provisions of the above paragraph or any other
factor.  Any such termination will be without liability on the part of any party
to the other, consistent with the provisions of Section 7.8 of the Stock
Purchase Agreement.

     If the foregoing correctly states your understanding, please so indicate by
signing where indicated below.
