assumes that the over-allotment option granted to the underwriters is not

                           Inventa Technologies, Inc.

Our Business

   We are a leading Internet professional services firm helping businesses to
use the Internet to engage in electronic commerce activities with other
businesses in order to improve their productivity and expand their online
offerings. We principally create and support:

  .  Electronic markets that allow businesses to interact over the Internet
     with their trading partners, conduct commerce electronically and process
     business transactions in real time

  .  Electronic customer relationship management systems that enable
     businesses to use the Internet to manage their relationships with
     business customers and other trading partners

   Since 1995, we have focused exclusively on engagements that enable our
clients to utilize the Internet to conduct electronic commerce with other
businesses. We believe that our early focus on business-to-business electronic
commerce engagements, our experience with business processes and our
methodologies for approaching these engagements enable us to rapidly and
efficiently implement advanced Internet systems for our clients. In 1999, our
clients included Automatic Data Processing, Inc., Amkor Technology, Inc.,
Cadence Design Systems, Inc., Citigroup, Inc., Crane Co., ePolicy.com, Fujitsu
PC Corporation, GoTo.com, Inc., Pure Markets Corporation, Shaman
Botanicals.com, Siemens Corporation, SMART Modular Technologies, Inc., Sun
Microsystems, Inc. and Trade Pacific Investments Limited, or tradepac.com.

   Examples of some of our recent engagements include:

  .  GoTo.com -- we designed an electronic customer relationship management
     system that allows our client and its customers to track the progress of
     customer care. Among other features, the system allows users to access
     answers to frequently asked questions in real time

  .  Pure Markets -- we created an electronic market for commercial leasing
     transactions that provides for online bidding, execution of leasing
     transactions and automation of routine business processes

  .  tradepac.com -- we designed an electronic market for inventory
     liquidation that provides for online bidding and that matches buyers
     worldwide with sellers from the Asia-Pacific region

Our Solution

   We deliver our services through teams of talented professionals with
extensive experience in business process analysis, project management and
software engineering. Using our proprietary LightSpeed delivery model and i2K
architectural framework, our professionals are able to quickly design and
engineer Internet-based electronic commerce applications that are integrated
with our clients' existing internal systems. Our approach allows us to quickly
deliver, with predictable fees and project schedules, complex systems that are
capable of being rapidly expanded and extended to handle large numbers of
transactions and connections to trading partners' systems.

   We engineer our e-commerce systems to facilitate:

  .  integration of complex Internet and legacy technologies with multiple
     business processes within a company and with its trading partners'
     systems

                                       1
<PAGE>


  .  integration of multiple databases to allow the flow of information in
     multiple directions

  .  real-time access by trading partners from a variety of technology
     platforms

  .  flexibility in accommodating the variety of contractual relationships,
     processes and payment methods that exist between businesses

   Our experience and expertise have allowed us to offer two products in the
form of packaged service offerings, eCare and eSales. eCare is our Internet-
based customer support service offering developed to enable our clients to
provide high-quality customer service and improve their customer retention.
eSales is our packaged service offering developed to help clients generate
revenue through Internet-based channels. Each of our packaged service offerings
addresses predetermined business functions and is implemented using a
combination of commercially available software and the collective knowledge of
our professionals. We believe that our packaged service offerings allow us to
leverage our extensive experience, reduce our project risk and speed the time
in which our clients reach the market.

Our Market Opportunity

   Businesses are increasingly using electronic commerce to interact with other
businesses. This enhances their competitive positions by improving operating
efficiencies, strengthening their relationships with trading partners and
enabling them to identify and capitalize on business opportunities. Developing
and supporting business-to-business electronic commerce systems requires
substantial expertise with respect to, among other matters:

  .  design of new business processes and systems that integrate with
     existing operations

  .  selection of appropriate Internet technologies

  .  management of a fast-paced implementation process

   Many businesses lack this expertise. As a result, an increasing number of
businesses from start-up ventures to large corporations engage Internet
professional services firms like ours to help them design, implement and
integrate their electronic commerce systems. International Data Corporation
estimates that the market for Internet professional services will grow from
$7.8 billion in 1998 to $78.6 billion in 2003, representing a 59% compound
annual growth rate.

Our Strategy

   Our strategy is to enhance our position and reputation as a leading provider
of Internet professional services for businesses to interact electronically
with other businesses. The key elements of our growth strategy are to:

  .  maintain our exclusive focus on engagements that enable our business
     clients to utilize the Internet to engage in electronic commerce with
     other businesses

  .  maintain our technology leadership by pursuing highly complex
     engagements

  .  continue to offer packaged services such as eCare and eSales and
     introduce new packaged services that target other business processes

  .  hire, train and retain skilled professionals and maintain a culture that
     fosters innovation

  .  leverage our reputation for client satisfaction and innovation to
     attract new engagements from both new and existing clients

                      Summary Consolidated Financial Data

   The following table summarizes the consolidated statement of operations and
consolidated balance sheet data for our business. For a more detailed
explanation of this financial data, see "Selected Consolidated Financial Data,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and our consolidated financial statements located elsewhere in this
prospectus.

   The unaudited pro forma consolidated balance sheet data reflects the
following assumptions:

  . issuance of 1,350,000 shares of our common stock with a fair value of
    $14.9 million in connection with the acquisition of XTEND-Tech, Inc.,
    which had an effective date of January 1, 2000

  . acquisition of assets and liabilities of XTEND-Tech. See details in our
    consolidated financial statements located elsewhere in this prospectus.

  . receipt of approximately $22.2 million from the issuance of 3,000,000
    shares of series D mandatorily redeemable convertible preferred stock on
    January 19, 2000, at $7.41 per share

  . conversion of 1,000,000 shares of our series A convertible preferred
    stock and 13,615,511 shares of our series B, C and D mandatorily
    redeemable convertible preferred stock into 14,615,511 shares of our
    common stock upon the completion of this offering

   See Note 1 of the notes to our consolidated financial statements for a
description of the methods we used to compute our weighted average shares and
basic and diluted net loss per share and pro forma basic and diluted net loss
per share.

   The unaudited pro forma, as adjusted, consolidated balance sheet data gives
effect to the sale of the shares offered by us at an assumed initial public
offering price of $11.00 per share, the midpoint of the anticipated range, and
the application of the net proceeds as described in "Use of Proceeds," after
deducting the estimated underwriting discount and estimated offering expenses.
In addition, the unaudited pro forma, as adjusted, balance sheet data gives
effect to the sale of 293,255 shares of common stock to be issued to holders of
series D preferred stock in a private placement to be made contemporaneously
with this offering and the application of the net proceeds of $3.0 million.

                                  RISK FACTORS

   Investing in shares of our common stock involves risks. You should carefully
consider the risks described below and other information in this prospectus
before making an investment decision. If any of the following risks actually
occur, our business, financial condition, results of operations and reputation
could be harmed. As a result, the trading price of our common stock may
decline, and you may lose all or part of your investment.

                         Risks Related to Our Business

We may have difficulty managing our growth, which could damage our ability to
retain clients and become profitable

   Our growth has placed significant demands on our management and other
resources. Our revenues for the year ended December 31, 1999, increased
approximately 69% from the year ended December 31, 1998. Our staff increased
from 57 full-time employees at December 31, 1998, to 245 at February 29, 2000.
Our future success will depend on our ability to manage our growth, including:

  . continuing to train, motivate, manage and retain our existing employees
    and to attract and assimilate new employees

  . maintaining project quality

  . maintaining high rates of employee utilization

  . accurately estimating time and resources required to complete engagements

  . developing and improving our operational, financial, accounting and other
    internal systems and controls

  . improving our business development capabilities

   If we are unable to manage our growth, our ability to retain clients and
become profitable could be damaged.

We have a history of operating losses, and we may never achieve significant or
sustained profitability

   We reported an operating loss of $10.9 million and a net loss of $15.8
million for the year ended December 31, 1999. We anticipate incurring losses in
2000 and 2001 as well. As we strive to grow our business, we expect to spend
significant funds for general corporate purposes, including working capital,
marketing, recruiting and hiring additional personnel, upgrading our
infrastructure and expanding into new geographic markets. Although our revenues
have increased in recent periods, we may not sustain these growth rates. To the
extent that our revenues do not increase at a rate commensurate with these
costs and expenditures, our results of operations and our stock's performance
could be harmed. In particular, we expect that our plan for increases in
expenses and capital expenditures over the next year will result in higher
operating losses. If we achieve profitability in the future, it may or may not
be sustainable.

If we do not retain our key management personnel and professionals or if we
fail to recruit additional professionals, our ability to serve existing and new
clients would be impaired

   Our business is labor intensive, and our success depends on identifying,
hiring, training and retaining experienced, knowledgeable management and
professionals. This dependence is particularly important to our business
because we believe personal relationships are critical to obtaining and
maintaining a cohesive culture. In 1999, 8.7% of our professional staff and
14.5% of our non-professional staff, which includes management and support
staff, left us. If a significant number of our senior management personnel or
professionals leave, we may be unable to complete or retain existing
engagements or bid for new projects. In addition, if any of these key employees
joins a competitor or forms a competing company, some of our clients might
choose to use the services of that competitor or new company instead of our
own.

                                       5
<PAGE>

   Even if we retain our current employees, we must continually recruit and
train talented professionals in order for our business to grow. There is
currently a shortage of qualified professionals in the Internet professional
services field, and this shortage is likely to continue. Furthermore, there is
significant competition for employees with the skills required to perform the
services we offer. We may not be able to attract a sufficient number of
qualified employees in the future, and we may not be successful in motivating
and retaining the employees we do attract. If we cannot attract, motivate and
retain qualified management and professionals, our ability to provide our
services to new and existing clients will be impaired.

Our management team has limited experience working together, which could affect
their ability to function effectively as a team

   We have employed our president and chief executive officer only since
January 1999. Five of our other officers, including our chief financial
officer, have joined us within the past 12 months. Therefore, there has been
little or no opportunity to evaluate the effectiveness of our executive
management team. The failure of our executive management to function
effectively as a team may hurt our ability to manage our business and growth,
obtain and execute client engagements, maintain a cohesive culture and compete
effectively.

We depend heavily on a limited number of clients. The loss of a principal
client or a reduction in the work we perform for any particular client could
harm our reputation and reduce our revenues

   We derive a significant portion of our revenue from a limited number of
clients. In 1999, our five largest clients accounted for approximately 75% of
our revenues, with ADP and ePolicy.com each accounting for over 10% of our
revenues. Our clients retain us on an engagement-by-engagement basis, rather
than under long-term contracts. Our contracts typically provide that our
clients can terminate the contracts without penalty. There is a risk that once
we complete an engagement, these principal clients may not retain us for
additional work in the future. Any cancellation, deferral or reduction in work
performed for one of these principal clients or a number of smaller clients
could harm our reputation and reduce our revenues.

Our business may be harmed by cost overruns and penalties associated with
fixed-price, fixed-time contracts if we fail to accurately estimate the time
and resources necessary for the performance of our services

   For the year ended December 31, 1999, approximately 88% of our revenues was
derived from fixed-price, fixed-time contracts. We expect that most of our
future revenues will continue to be derived from fixed-price, fixed-time
contracts. Less than 10% of our contracts provide for financial penalties if we
do not meet specified deadlines. To date, we have not had to pay any of these
penalties. To mitigate losses from fixed-price, fixed-time contracts, we must,
among other things:

  . accurately estimate the resources required to perform these contracts

  . complete our clients' projects on a timely basis

  . effectively manage our clients' expectations

  . complete projects within budget and to our clients' satisfaction

   If we do not successfully manage these project risks, we could be exposed to
cost overruns and penalties. If this occurs in connection with a large project
or a sufficient number of projects, we may suffer lower gross margins and
delays in recognizing revenues, and our financial condition, results of
operations and reputation could be harmed.

Quarterly fluctuations in our revenues and earnings could affect the market
price of our common stock

   Our quarterly revenues and earnings have varied in the past and may vary
significantly. This fluctuation may cause our operating results to be below the
expectations of securities analysts and investors, and the price of our stock
may fall. Factors that could cause quarterly fluctuations include:

  . the number, size and scope of client engagements commenced or completed
    during a quarter

                                       6
<PAGE>

  . professional staff utilization rates

  . unanticipated project terminations, delays or deferrals

  . the accuracy of our estimates of resources required to complete ongoing
    projects

  . the contractual terms and degree of completion of projects in which we
    are engaged

   A large percentage of our expenses, particularly employee compensation and
rent, are fixed in advance of any particular quarter. In addition, we may incur
unanticipated expenses relating to increased utilization of subcontractors. Any
decline in revenues or earnings, unanticipated project termination or delay, or
greater than expected costs for any quarter could harm our results of
operations and result in a decline in the market price of our common stock,
even if not reflective of any long-term problems with our business.

Competition from larger, more established competitors with greater financial
resources and from new competitors could result in price reductions and reduced
revenues and loss of current and future clients

   The Internet professional services market is intensely competitive. We
expect competition to continue and intensify, which could result in price
reductions, reduced revenues and the loss of current and future clients. Our
competitors fall into six major categories:

  . Internet professional services firms

  . information technology consulting and systems integration firms

  . services divisions of computer hardware and software vendors

  . web design firms

  . information technology strategy consulting firms

  . in-house information technology departments of our current and potential
    clients

   Many of our competitors have longer operating histories and client
relationships, greater resources, larger client bases and greater brand or name
recognition than we have. Our competitors may be able to respond more quickly
to technological developments and changes in clients' needs. This ability of
our competitors may place us at a disadvantage in responding to our
competitors' pricing strategies, technological advances, advertising campaigns,
strategic partnerships and other initiatives.

   Further, there are low barriers to entry into our industry segment. We do
not own any technologies that preclude or inhibit potential competitors from
entering our industry. Since the potential market opportunity is large, while
costs to develop and provide Internet professional services are relatively low,
we expect to continue to face additional competition from new competitors.

If we do not keep pace with technological changes, industry standards and
client preferences, our reputation could be harmed, and we could lose clients,
which would reduce our revenues

   Our success will depend in part on our ability to develop information
technology solutions that keep pace with continuing changes in Internet
technology, evolving industry standards and changing client preferences. We may
not be successful in addressing these developments on a timely basis, or at
all. Our failure to respond quickly and cost-effectively to new developments
could harm our reputation and cause us to lose current and potential business
opportunities, resulting in reduced revenues.

   In particular, we have derived a significant portion of our revenues from
projects based primarily on:

  . open systems technologies

  . multi-tier software architectures

  . Internet-based architectures

                                       7
<PAGE>

   These areas are continuing to develop and are subject to rapid change. Any
factors impeding the acceptance of information technology systems using
Internet-based architectures could reduce our revenues and impair our results
of operations, especially if we are unable to develop skills and replacement
technologies for these types of information technology systems.

We may face intellectual property claims that could result in substantial costs
or limit our ability to use intellectual property in the future

   It is possible that other parties may assert infringement claims against us
in the future or claim that we have violated their intellectual property
rights. While we know of no basis for any claims of this type, authorship of
intellectual property rights can be difficult to verify. Competitors could
assert, for example, that former employees of theirs whom we have hired have
misappropriated their proprietary information for our benefit. A successful
infringement claim against us could damage us in the following ways:

  . we may be liable for damages and litigation costs, including attorneys'
    fees

  . we may be prohibited from further use of the intellectual property in
    dispute

  . we may have to license the intellectual property, incurring licensing
    fees

  . we may have to develop a non-infringing alternative, which could be
    costly and delay projects

  . we may have to indemnify clients with respect to losses incurred as a
    result of our infringement of the intellectual property

   Regardless of the outcome, an infringement claim could result in substantial
costs, diversion of resources and management attention, clients' termination of
project engagements and harm to our financial condition and reputation.

If we are not able to resell or reuse intellectual property developed for
specific clients, our ability to provide our services efficiently would be
impaired

   Our LightSpeed delivery model and i2K architectural model, as well as our
knowledge management system, known as Inside Inventa, depend heavily on using
information and techniques learned and developed during prior engagements.
Moreover, a portion of our business involves the development of software
applications for specific client engagements. Our clients generally retain
ownership of client-specific software, although we retain rights to some of the
applications, processes and other intellectual property developed in connection
with client engagements. Some clients have prohibited us from marketing the
applications developed for them, or similar applications, for specified periods
or to specified types of potential clients. Our clients may demand similar or
other restrictions in the future, and disputes may arise that affect our
ability to resell or reuse such applications, processes and other intellectual
property. These disputes could damage our relationships with our clients and
divert our management's attention. A successful suit that prevents us from
reusing information and techniques would also impair our ability to provide our
services efficiently.

If we are unable to maintain our reputation and expand our name recognition, we
may have difficulty in attracting new clients and retaining current clients and
professionals

   We believe that establishing and maintaining a good reputation and name
recognition are critical for attracting and retaining our clients and
professional staff. We also believe that the importance of reputation and name
recognition will increase due to the growing number of Internet professional
services firms. If our reputation is damaged or if potential clients are not
familiar with us or the services we provide, we may become less competitive or
lose our market position. Promotion and enhancement of our name will depend
largely on our success in continuing to provide effective Internet technology
solutions. If clients do not perceive our solutions to be effective or of high
quality, our brand name and reputation will suffer. In addition, if solutions
we provide have defects, critical business functions of our clients may fail,
and we could suffer adverse publicity as well as economic liability.

                                       8
<PAGE>

If we fail to secure written contracts, our ability to collect fees, protect
our intellectual property and protect ourselves from liability to others could
be impaired

   We attempt to protect ourselves by entering into written contracts with our
clients covering the terms and contingencies of a project engagement. In most
of our engagements, we begin work for clients on the basis of a limited
statement of work or a verbal agreement before a detailed written contract can
be finalized. To the extent that we fail to have detailed written contracts in
place, our ability to collect fees, recognize revenues, protect our
intellectual property and protect ourselves from liability to others may be
impaired.

We may need additional capital in the future, which may not be available to us.
The raising of any additional capital may dilute your ownership in us

   In the future, we may need to raise additional funds through public or
private debt or equity financings to take advantage of expansion or acquisition
opportunities, develop new solutions or compete effectively in the marketplace.

   Any additional capital raised through the sale of equity or equity-linked
debt securities would dilute your ownership percentage in us. Those securities
could also have rights, preferences or privileges senior to those of your
common stock. Furthermore, we may not be able to obtain additional financing
when needed or on terms favorable to us or our stockholders. If additional
financing is not available on favorable terms, or at all, this may limit our
ability to develop or enhance our services, take advantage of business
opportunities or respond to competitive pressures.

                         Risks Related to Our Industry

Our business may suffer if growth in the use of the Internet declines

   Because Internet technologies are central to many of our solutions, our
business depends upon continued growth in the use of the Internet by our
clients, prospective clients and their suppliers and other trading partners.
Capacity constraints caused by growth in Internet usage may, unless resolved,
impede further growth in Internet use. Factors that may affect Internet usage
or electronic commerce adoption include:

  . actual or perceived lack of security of information

  . congestion of Internet traffic or other usage delays

  . inconsistent quality of service

  . increases in costs of accessing the Internet

  . adverse government regulation

  . uncertainty regarding intellectual property ownership

  . reluctance of companies to adopt new business methods

  . costs associated with the obsolescence of existing infrastructure

  . lack of economic viability of the electronic commerce model

Our success will depend on market acceptance of our industry

   Widespread market acceptance of the outsourcing of the design, development
and maintenance of Internet-based applications to Internet professional
services firms like ours is uncertain. Many of our potential clients may
ultimately decide to perform these services in-house. In-house personnel may
have better access to both key client decision-makers and the information
required to prepare proposals for such solutions. If independent providers of
Internet professional services prove to be unreliable, ineffective or too
expensive, or if software

                                       9
<PAGE>

companies develop tools that are sufficiently user-friendly and cost-effective,
companies may instead choose to design, develop or maintain their Internet-
based applications internally. Our revenues will decline if the market for our
services does not continue to develop or develops more slowly than we expect,
or if the market does not accept our services.

Government regulation and legal uncertainties relating to the Internet could
decrease demand for our services, increase our operating costs or otherwise
harm our business

   Increased regulation of the Internet or taxation of electronic commerce
might slow the growth in use of the Internet, which could decrease demand for
our services, increase our cost of doing business or otherwise harm our
business. Congress, federal regulatory agencies and the states have recently
passed legislation or taken other actions regulating certain aspects of the
Internet, including:

  . online content                   . liability for third-party activities

  . interaction with children        . transmission of sexually explicit
                                       materials

  . copyright infringement           . defamation

  . user privacy                     . consumer protection

  . taxation                         . jurisdiction

  . access charges

   In addition, federal, state and local governmental organizations as well as
foreign governments are considering other legislative and regulatory proposals
that would regulate these and other aspects of the Internet. We do not know how
courts will interpret laws governing the Internet or the extent to which they
will apply existing laws to the Internet. Therefore, we are not certain how
existing or future laws governing the Internet or applied to the Internet will
affect our business.

                       Risks Related to our Common Stock

If the market price of our common stock fluctuates significantly, you may not
be able to sell our shares at or above the initial public offering price, and
therefore, you may suffer a loss on your investment

   The initial public offering price will be determined through negotiation
between us and representatives of the underwriters and may not be indicative of
the market price for our common stock after this offering.

   The market price of our common stock could fluctuate significantly as a
result of:

  . our susceptibility to quarterly variations in our operating results,
    which may cause us to fail to meet analysts' or investors' expectations

  . changes in financial estimates by the analysts following our stock

  . earnings and other announcements by, and changes in investors'
    evaluations of, Internet professional services firms

  . economic and stock market conditions specific to Internet professional
    services firms

  . changes in business or regulatory conditions affecting information
    technology services

  . announcements or implementation by us or our competitors of technological
    innovations or new products or services

  . trading volume of our common stock

   The securities of many companies have experienced significant price and
volume fluctuations in recent years, often unrelated to the companies'
operating performance. Specifically, market prices for securities of

                                       10
<PAGE>

Internet-related and technology companies have frequently reached elevated
levels, often following their initial public offerings. These levels, if
attained in the future, may not be sustainable and may not bear any
relationship to these companies' operating performances. If the market price of
our common stock reaches an elevated level following this offering, it may
significantly and rapidly decline. In the past, following periods of volatility
in the market price of a company's securities, stockholders have often
instituted securities class action litigation against the company. If we were
to become involved in securities litigation, it could cause a substantial loss
and divert resources and the attention of senior management from our business.

Because an active trading market for our common stock may not develop after
this offering, it may be difficult for you to sell your shares

   There is currently no trading market for our common stock. Accordingly, an
active public trading market may not develop or be sustained after this
offering. If an active and liquid trading market does not develop, you may have
difficulty selling your shares.

The sale or availability for sale of substantial amounts of our common stock
could cause our stock price to decline

   Sales of substantial amounts of our common stock in the public market after
the completion of this offering or the public perception that these sales could
occur could cause a decline in the market price of our common stock and could
impair our future ability to raise capital through offerings of our common
stock. There will be 25,196,929 shares of common stock outstanding immediately
after this offering including those shares issued upon conversion of the
convertible securities, shares issued in the contemporaneous private placement,
and those shares issuable at the close of this offering under an employment
agreement, or 25,721,929 shares if the underwriters exercise their over-
allotment option in full. The 3,500,000 shares sold in this offering will be
freely tradable without restriction or further registration under the
Securities Act, unless held by our "affiliates" as that term is defined in Rule
144 under the Securities Act. The remaining shares are "restricted securities,"
and will become eligible for sale in the public market at various times after
180 days after the date of this prospectus, subject to the limitations and
other conditions of Rule 144 under the Securities Act.

   In connection with this offering, we, our executive officers and directors
and 21 of our stockholders and their affiliates have agreed, except in limited
circumstances, not to sell the 20,533,342 shares of common stock owned by them
for 180 days after completion of this offering without the consent of Lehman
Brothers Inc. These shares, however, may be released from these restrictions by
Lehman Brothers Inc. at any time. We cannot predict what effect, if any, market
sales of shares held by principal stockholders or any other stockholder or the
availability of these shares for future sale will have on the market price of
our common stock.

   A number of our stockholders are parties to an agreement with us that
provides these stockholders with the right to require us to register the sale
of shares owned by them. These rights cover approximately 16,238,238 shares,
representing 64% of our common stock outstanding after this offering and will
also cover any shares obtained by these stockholders from time to time.
Registration of these shares of our common stock would permit the sale of these
shares without regard to the restrictions of Rule 144 and Rule 144(k).

Concentration of ownership of our common stock may limit your ability to
influence corporate matters

   Immediately following this offering, our executive officers and directors,
or entities controlled by them, will own approximately 77% of the outstanding
shares of our common stock.

   If our significant stockholders choose to act or vote together on corporate
matters, they will have the power to control the approval of any action
requiring the approval of our stockholders, including any mergers,
acquisitions, sales of all of our assets or amendments to our certificate of
incorporation. In addition, without the consent of these stockholders, we could
be prevented from entering into transactions that could be beneficial to us.
Also, third parties could be discouraged from making a tender offer or bid to
acquire our company at a price per share that is above the then-prevailing
market price.

                                       11
<PAGE>

The net proceeds of this offering may be allocated in ways with which you and
other stockholders may not agree

   Our management will have significant flexibility in applying the proceeds we
receive in this offering. Because the proceeds are not required to be allocated
to any specific purpose, investment or transaction, you cannot determine at
this time the value or propriety of our management's application of the
proceeds on our behalf and you and other stockholders may not agree with our
management's decisions.

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

   If you purchase common stock in this offering, you will pay more for your
shares than the amounts paid by existing stockholders for their shares. As a
result, you will experience immediate and substantial dilution of approximately
$8.58 per share, representing the difference between our book value per share
as of December 31, 1999, after giving effect to this offering and the initial
public offering price. In addition, you may experience further dilution to the
extent that shares of our common stock are issued upon the exercise of stock
options or under our employee stock purchase plan. All of the shares issuable
upon the exercise of currently outstanding stock options will be issued at a
purchase price less than the public offering price per share in this offering.

Antitakeover provisions of Delaware's General Corporation Law and our
certificate of incorporation could delay or deter a change in control

   Amendments to our certificate of incorporation and our bylaws, as well as
various provisions of the Delaware General Corporation Law, may make it more
difficult to effect a change in control of our company. The existence of these
provisions may adversely affect the price of our common stock, discourage third
parties from making a bid for us or reduce any premiums paid to our
stockholders for their common stock. For example, our certificate of
incorporation authorizes our board of directors to issue up to 14,779,511
shares of blank check preferred stock and to attach special rights and
preferences to this preferred stock. The issuance of this preferred stock may
make it more difficult for a third party to acquire control of us. Our
certificate of incorporation also provides for the division of our board of
directors into three classes as nearly equal in size as possible with staggered
three-year terms. This classification of the board of directors could have the
effect of making it more difficult for a third party to acquire our company or
of discouraging a third party from acquiring control of us.

                                USE OF PROCEEDS

   We estimate that the net proceeds to us from the offering will be
approximately $34.2 million at an assumed initial public offering price of
$11.00 per share, the mid-point of the anticipated range, and approximately
$39.6 million if the underwriters exercise the over-allotment option in full,
in each case, after deducting the estimated underwriting discount and estimated
offering expenses payable by us.

   We intend to use the net proceeds of the offering primarily for general
corporate purposes, including:

  . reducing outstanding debt of approximately $4.0 million, which is due
    November 30, 2000, and bears interest at the prime rate plus 2.00%
    (currently 10.75%). The proceeds of this loan were used to pay off our
    equipment lease line with a balance of $375,000. The remaining proceeds
    are being used to fund working capital and to purchase equipment.

  . increasing our recruiting capabilities

  . expanding our sales and marketing capabilities

  . increasing our brand awareness

  . investing in our internal systems and processes

  . opening new offices

   In addition, we may use the proceeds to make selected strategic investments
or acquisitions. We cannot specify with certainty all or particular allocations
of the use of proceeds from this offering.

                                DIVIDEND POLICY

   We have never declared or paid any cash dividends, and we do not anticipate
paying cash dividends in the foreseeable future. We currently intend to retain
future earnings, if any, to finance operations and the expansion of our
business. Any future determination to pay dividends will be at the sole
discretion of our board of directors and will depend upon our financial
condition, operating results, capital requirements and other factors our board
of directors deems relevant. In addition, our current lines of credit
facilities restrict our ability to declare and pay any dividends without the
prior consent of our lenders.

                                    DILUTION

   On a pro forma basis after giving effect to the conversion of 11,615,511
outstanding shares of series A, B, and C preferred stock, the issuance and
subsequent conversion of 3,000,000 shares of series D preferred stock at $7.41
per share, the issuance of 1,350,000 shares of common stock in connection with
the acquisition of XTEND-Tech, and the acquisition of the net tangible assets
of XTEND-Tech, our pro forma net tangible book value as of December 31, 1999,
was $22.2 million or $1.07 per share of common stock. Pro forma net tangible
book value per share represents the amount of our total tangible assets reduced
by the amount of our total liabilities and divided by the total number of
shares of common stock outstanding. After giving effect to the sale of
3,500,000 shares of common stock offered by this prospectus at an assumed
initial public offering price of $11.00 per share and receipt of the estimated
net proceeds from the sale, and the sale of 293,255 shares at $10.23 per share
in connection with our contemporaneous private placement and receipt of the
estimated net proceeds of $3.0 million from the sale, our pro forma net
tangible book value as of December 31, 1999, would have been approximately
$59.4 million or $2.42 per share. This represents an immediate increase in net
tangible book value of $1.35 per share to existing stockholders and an
immediate dilution of $8.58 per share to the new investors. If the initial
public offering price is higher or lower, the dilution to new investors will
be, respectively, greater or less. The following table illustrates this per
share dilution:

   The following table sets forth as of December 31, 1999, assuming the pro
forma effects described above, the difference between the number of shares of
common stock purchased from us, the total consideration and the average price
per share paid by the existing stockholders and by the new investors at an
assumed initial public offering price of $11.00 per share for shares purchased
in this offering, before deducting the estimated underwriting discounts and
estimated offering expenses and $10.23 for shares purchased in the
contemporaneous private placement:

</TABLE>

   This table assumes that the underwriters do not exercise their over-
allotment option. If the underwriters' over-allotment option is exercised in
full, the pro forma, as adjusted net tangible book value per share after giving
effect to this offering would be $2.60 per share. After deducting underwriting
discounts and commissions and estimated transaction expenses, the increase in
the net tangible book value per share to existing stockholders would be $2.59
and the dilution to new public investors would be $8.41 per share.

   This table also assumes that no options or warrants have been or are
exercised after December 31, 1999. As of December 31, 1999, there were
outstanding options to purchase an aggregate of 3,492,000 shares of common
stock at a weighted average exercise price of $0.42 per share, excluding
warrants to purchase 160,000 shares of series C preferred stock at $2.50 per
share. If all such options and warrants had been exercised on December 31,
1999, and the underwriters' over-allotment option is exercised in full, our net
tangible book value on that date would have been $66.7 million or $2.33 per
share, the increase in net tangible book value attributable to new investors
would have been $1.26 per share, and the dilution in net tangible book value to
new investors would have been $8.67 per share.

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

   You should read the following discussion together with "Selected
Consolidated Financial Data," our consolidated financial statements and the
related notes to those consolidated financial statements located elsewhere in
this prospectus. In addition to historical information, this discussion
contains forward-looking information that involves risks and uncertainties. Our
actual results could differ materially from those anticipated by such forward-
looking information due to competitive factors, risks associated with our
expansion plans and other factors discussed under "Risk Factors" and elsewhere
in this prospectus.

Overview

   Revenues. Our revenues are substantially derived from fixed-price, fixed-
time contracts. Revenues earned under fixed-price, fixed-time projects are
recognized on the percentage-of-completion method based on the ratio of actual
costs incurred to total estimated costs. We recognize revenues on our other
projects on a time and materials basis. Revenues exclude reimbursable expenses
charged to clients.

   Approximately 88% of our revenues for the year ended December 31, 1999, was
derived from fixed-price, fixed-time arrangements.

   Due to our use of fixed-price, fixed-time contracts, our operating results
may be harmed by inaccurate estimates of costs and time required to complete
projects. Therefore, we closely monitor project progress through a series of
processes designed to help estimate cost and time to completion, including a
detailed review at the end of each project stage to determine project
percentage of completion. We typically invoice for an advance payment from our
clients upon contract signing, with additional billings upon our attainment of
project milestones. This practice of invoicing in advance of revenue
recognition in combination with significant new projects in the fourth quarter
of 1999 have resulted in an increase in the current year's receivables, as a
percentage of revenues, as compared to prior years. Deferred revenues consist
primarily of payments received in advance of services rendered. We recognize
those payments as revenues upon performance of services.

   Cost Structure. Project personnel expenses consist primarily of payroll,
associated taxes, employee benefits, any third-party fees and net travel costs
incurred in the delivery of our services. Sales and marketing expenses consist
primarily of personnel costs and commissions as well as the costs associated
with the development and maintenance of our marketing materials and programs.
General and administrative expenses consist primarily of the costs associated
with operations management, finance, human resources, information systems,
facilities and other administrative support for project personnel.

   We regularly review the fees we charge for our services, our employee
compensation and our overhead costs in an effort to remain competitive within
our industry. In addition, we monitor the progress of our projects with our
clients' senior management. Monitoring the costs and progress associated with
each project is aided by our intranet-based project management systems. We
manage the activities of our service delivery personnel by closely monitoring
project schedules and staffing requirements for new projects. Most of our
client projects can, and may in the future, be terminated by our clients
without penalty. However, our contracts generally provide that we will be
compensated based on the percentage of work completed relative to the fixed
price of the engagement. Termination of a client project could require us to
maintain underutilized employees, resulting in a higher than expected number of
inactive professionals. We maintain a sufficient number of senior professionals
to oversee existing and anticipated client projects and participate in our
sales efforts to engage new client projects.

   Variability of Operating Results. Our operating results have fluctuated from
quarter to quarter and may continue to fluctuate in the future. These
fluctuations may be significant. We may not always forecast accurately the
frequency and duration of our projects. We incur expenses, which are mainly
fixed expenses, based on our expectations concerning the costs of our future
projects. We may not be able to reduce our

                                       18
<PAGE>

spending in a timely manner to compensate for any shortfall in our projected
revenues. In the event of such a shortfall, our expenses as a percentage of our
revenues would increase. Our quarterly operating results may not meet the
expectations of analysts or investors. This may cause a decline in the market
price of our common stock.

   Recent Net Losses.  Our net loss was $10.9 million for the year ended
December 31, 1999, compared to $1.7 million for the year ended December 31,
1998. We primarily attribute our increased net losses to higher project
personnel expenses, sales and marketing expenses and general and administrative
expenses. The overall increase in expenses was primarily attributable to costs
incurred to expand or increase the number of project personnel as well as
significant investment in office facilities and related infrastructure
management and administrative personnel and sales and marketing.

   Recent Events. In January 2000, we acquired the business of XTEND-Tech, a
30-employee information technology consulting organization serving Global 1000
companies. This acquisition will expand the breadth of our service offerings
and contribute to our future revenue growth. XTEND-Tech has a cost structure
that is similar to ours. We issued 1,350,000 shares of our common stock in
connection with this acquisition with an estimated fair value of approximately
$14.9 million. This consideration consisted of a combination of the purchase
price paid for the outstanding common stock of XTEND-Tech and consideration to
certain employee stockholders of XTEND-Tech for continued employment with us.
The acquisition was accounted for using the purchase method of accounting. The
total amount of the consideration treated as purchase price for this
acquisition was approximately $8.8 million and was allocated to the tangible
and intangible assets acquired and liabilities assumed based upon their
respective fair values at the acquisition date. The amortization of the
intangible assets will occur over the estimated periods to be benefited. In
connection with this acquisition we signed restricted stock agreements with
employee-stockholders of XTEND-Tech as consideration for continued employment.
The fair value of the unvested shares, which relate to these restricted stock
agreements, amounting to $6.1 million, has been recorded as deferred stock-
based compensation, which will be amortized over the three-year vesting period
of the restricted stock.

1999 Compared to 1998

   Revenues. Our revenues increased 69% to $13.5 million for the year ended
December 31, 1999, compared to $8.0 million for the year ended December 31,
1998. We attribute our revenue growth primarily to an increase in the volume of
services delivered to new clients. We will continue to focus our efforts on new
client capture and expect this trend to continue. In 1999, our five largest
clients accounted for approximately 75% of our revenues. In 1998, our five
largest clients accounted for approximately 85% of our revenues. Compared to
the fourth quarter of 1998, the decline in revenues in the first quarter of
1999 can be attributed to a delay by a major client in its transition from its
legacy business systems. The decline in the second quarter of 1999 can be
attributed to the loss of a major client.

   Project Personnel Expenses. Project personnel expenses increased $5.8
million, or 208%, to $8.6 million for the year ended December 31, 1999, from
$2.8 million for the year ended December 31, 1998. The increase was primarily
attributable to the hiring of additional project personnel to accommodate
current and anticipated increases in demand for our services. This increase in
project personnel resulted in a decline in utilization levels to approximately
60% in 1999, from an average of approximately 76% in 1998. Headcount for
project personnel as of December 31, 1999, was 112 compared to 36 as of
December 31, 1998. As a percentage of revenues, project personnel expenses were
63% for the year ended December 31, 1999, and 35% for the year ended December
31, 1998.

   Sales and Marketing Expenses. Sales and marketing expenses increased $2.4
million, or 130%, to $4.2 million for the year ended December 31, 1999, from
$1.8 million for the year ended December 31, 1998. The increase was due to our
investment in our sales and marketing programs. Headcount for sales and
marketing personnel increased to 15 at December 31, 1999, from 8 at December
31, 1998. As a percentage of revenues, sales and marketing expenses were 31%
for the year ended December 31, 1999, and 23% for the year ended December 31,
1998.

   General and Administrative Expenses. General and administrative expenses
increased $4.9 million, or 108%, to $9.4 million for the year ended December
31, 1999, from $4.5 million for the year ended December 31, 1998. Office rent
expenses increased to $828,000 for the year ended December 31, 1999, from
$214,000 for the year ended December 31, 1998. Headcount for managerial and
administrative personnel increased to 39 as of December 31, 1999, from 13 as of
December 31, 1998. The increases in office rent expenses accounted for 12% of
the overall increase. In addition, personnel expenses accounted for 68% of this
increase. As a percentage of revenues, general and administrative expenses were
70% for the year ended December 31, 1999, and 56% for the year ended December
31, 1998.

   Depreciation. Depreciation expense increased $311,000, or 124%, to $562,000
for the year ended December 31, 1999, from $251,000 for the year ended December
31, 1998. The increase was attributable to capital expenditures for new
equipment and leasehold improvements.

   Amortization of Deferred Stock-based Compensation. We recorded $1.6 million
in amortization of deferred stock-based compensation expense for the year ended
December 31, 1999. This expense represented the amortization of the difference
between the deemed fair value of the underlying options at the time of grant
and their exercise price.

   Other Income (Expense), Net. Other expense was $5,000 for the year ended
December 31, 1999, compared to income of $36,000 for the year ended December
31, 1998. The variance was primarily due to an increase in interest expense.
The average aggregate balance outstanding on our line of credit and term loan
was $1.2 million during the year ended December 31, 1999, as compared to
$172,000 during the year ended December 31, 1998. Interest expense under these
facilities was $106,000 for the year ended December 31, 1999, and $56,000 for
the year ended December 31, 1998.

   Income Tax Expense. We incurred income tax expense of $15,000 for the year
ended December 31, 1999, and $2,000 for the year ended December 31, 1998. As of
December 31, 1999, we had approximately $13.0 million of federal net operating
loss carryforwards and approximately $11.0 million of state net operating loss
carryforwards available to offset future taxable income. The federal net
operating loss carryforwards will expire between 2011 and 2019, and the state
net operating loss carryforwards will expire between 2004 and 2006, if not
utilized.


                                       20

   Under the Tax Reform Act of 1986, the amounts of and the benefit from net
operating losses that can be carried forward may be limited upon a cumulative
stock ownership change of more than 50% over a three-year period. Any unused
annual limitation may be carried forward to future years for the balance of the
net operating loss carryforward period.

1998 Compared to 1997

   Revenues. Our revenues increased 53% to $8.0 million for the year ended
December 31, 1998, compared to $5.2 million for the year ended December 31,
1997. We attribute approximately 35% of our revenue growth to an increase in
the volume of services delivered to new clients and approximately 65% to
additional projects for existing clients. In 1998, our five largest clients
accounted for approximately 85% of our revenues. In 1997, our five largest
clients accounted for approximately 55% of our revenues.

   Project Personnel Expenses. Project personnel expenses increased by
$122,000, or 5%, to $2.8 million for the year ended December 31, 1998, from
$2.7 million for the year ended December 31, 1997. The increase was
attributable to the hiring of additional project personnel during the second
half of 1998. As a percentage of revenues, project personnel expenses declined
to 35% for the year ended December 31, 1998, compared to 51% for the year ended
December 31, 1997. The decrease in project personnel expenses in 1998 as a
percentage of revenues was the result of our delay of hiring additional
personnel until the second half of 1998, which resulted in a higher utilization
rate and a slower growth of expenses relative to the growth in revenues.

   Sales and Marketing Expenses. Sales and marketing expenses increased by
$167,000, or 10%, to $1.8 million for the year ended December 31, 1998, from
$1.7 million for the year ended December 31, 1997. The increase in these
expenses was primarily attributable to the hiring of business development and
marketing personnel, increased public relations activities and the
implementation of new and continuation of our existing marketing programs.
Headcount for sales and marketing personnel increased to eight at December 31,
1998, from five at December 31, 1997. As a percentage of revenues, sales and
marketing expenses were 23% for the year ended December 31, 1998, and 32% for
the year ended December 31, 1997.

   General and Administrative Expenses. General and administrative expenses
increased $1.0 million, or 31%, to $4.5 million for the year ended December 31,
1998, from $3.5 million for the year ended December 31, 1997. The increase was
primarily attributable to expenses incurred to accommodate our current and
anticipated growth, including the expansion of our office facilities and the
increased cost of management and administrative personnel and other general
operating expenses in the areas of accounting, human resources and general
operations. Office rent expenses increased to $214,000 for the year ended
December 31, 1998, from $157,000 for the year ended December 31, 1997.
Headcount for management and administrative personnel increased to 12 at
December 31, 1998, from six at December 31, 1997. As a percentage of revenues,
general and administrative expenses were 56% for the year ended December 31,
1998, and 67% for the year ended December 31, 1997. Also, reflected in the
results for the quarter ended December 31, 1998, was a reduction in costs
associated with a decrease in hiring activity, an adjustment to the incentive
compensation accrual, based on a revision of management's estimate of the
required level, and savings associated with a reduction in professional
services expenses.

   Depreciation. Depreciation increased by $64,000 to $251,000 for the year
ended December 31, 1998, from $187,000 for the year ended December 31, 1997.
The increase was related to increased investments in furniture and equipment.

   Amortization of Deferred Stock-based Compensation. We recorded $50,000 in
amortization of deferred stock-based compensation expense for the year ended
December 31, 1998. This expense represented the amortization of the difference
between the deemed fair value of the underlying options at the date of grant
and their exercise price.

   Non-Recurring Expenses on Closing of Foreign Operations. In November 1998,
we announced our intention to close our operations in Malaysia. In conjunction
with this announcement, we recorded a reserve of

                                       21
<PAGE>

$250,000 for anticipated liquidation costs of our Malaysian subsidiary. This
amount consisted of $157,000 for the write-down from the liquidation of the
assets, $47,000 for remaining trade obligations and $46,000 for legal and other
professional services to be provided during the liquidation process. Operations
ceased during 1998, and all employee severance related costs were incurred
prior to December 31, 1998. During 1999, the liquidation of the assets and
settlement of the obligations was completed. As of December 31, 1999, $41,000
remains accrued to cover a pending claim from a former customer of the
Malaysian subsidiary. We anticipate that this claim will be settled during
2000.

   Other Income (Expense), Net. Other income increased by $115,000 to $36,000
for the year ended December 31, 1998, from an expense of $79,000 for the year
ended December 31, 1997. The increase was primarily attributable to increased
interest income and a decrease in interest expense related to borrowings under
our revolving line of credit and capital lease obligations. Interest expense
was $56,000 for the year ended December 31, 1998, and $83,000 for the year
ended December 31, 1997.

   Income Tax Expense. We incurred a $2,000 income tax expense for the year
ended December 31, 1998, as compared with $90,000 for the year ended December
31, 1997. As of December 31, 1998, we had approximately $3.0 million of federal
net operating loss carryforwards and $2.0 million of state net operating loss
carryforwards available to offset future taxable income.

Liquidity and Capital Resources

   Since 1997, we have financed our operations primarily from sales of
preferred stock and borrowings under a line of credit and a term loan from a
commercial bank. As of December 31, 1999, we have raised approximately $17.7
million, net of offering expenses, $13.7 million through the sale of our
preferred stock and $4.0 million from a term loan. At December 31, 1999, we had
approximately $3.2 million in cash and cash equivalents.

   Net cash used in operating activities was $2.2 million for the year ended
December 31, 1997, $340,000 for the year ended December 31, 1998, and $8.7
million for the year ended December 31, 1999. Cash used in operating activities
in each of these periods was primarily the result of net losses, adjusted for
non-cash items primarily related to depreciation, increases in accounts
receivable and fees and unbilled revenues resulting from increased sales
revenue in the fourth quarter, partially offset by increases in accounts
payable and accrued expenses resulting from increased operating expenses
associated with the sales revenue growth. The losses during 1999 resulted in
negative working capital of $1.9 million for the period ending December 31,
1999, versus positive working capital of $429,000 and $3.8 million,
respectively, for the periods ending December 31, 1997, and December 31, 1998.

   Net cash used in investing activities was $50,000 for the year ended
December 31, 1997, $460,000 for the year ended December 31, 1998, and $1.3
million for the year ended December 31, 1999. Cash used in investing activities
in each period consisted primarily of purchases of furniture and equipment.

   Net cash provided by financing activities was $2.9 million for the year
ended December 31, 1997, $4.9 million for the year ended December 31, 1998, and
$8.4 million for the year ended December 31, 1999. In 1997 and 1998, the cash
provided by our financing activities was primarily from the sale of our
preferred stock. For the year ended December 31, 1999, the cash provided from
our financing activities was primarily from the sale of our preferred stock and
borrowings under a term loan and equipment leases.

   As of December 31, 1999, our principal commitments consisted of obligations
under a term loan and under equipment leases, which funded our purchases of
furniture and equipment. Our equipment leasing arrangements consist primarily
of us paying rental fees to third-party leasing providers at interest rates
between 11.00% and 13.00%. Borrowings under the term loan bear interest at the
prime rate plus 2.00% (10.75% currently), with accrued interest paid monthly,
and are due at November 30, 2000. As of December 31, 1999, we borrowed $4.0
million, the entire amount available under the term loan. We have $2.0 million
available under a revolving line of credit. Borrowing under the line of credit
is limited to the lesser of 80% of the amount of eligible accounts receivable
or $2.0 million and bears interest at the prime rate plus 2.00% (10.75%
currently). We have never borrowed under the line of credit. Although we have
no material commitments for capital expenditures, we anticipate an increase in
our capital expenditures consistent with anticipated growth in our operations,
infrastructure and personnel.

   Subsequent to December 31, 1999, we issued 3,000,000 shares of series D
preferred stock in a private placement for gross proceeds of approximately
$22.2 million. The difference between the deemed fair value of the Series D
preferred stock of $11.00, the mid-point of the range of share prices
anticipated for this offering, and the price per share of $7.41 was considered
to be a beneficial conversion feature analogous to a dividend to the preferred
stockholders. The value of the beneficial conversion feature of $10.8 million
will be recognized in fiscal 2000 as a non-cash charge to net loss attributable
to common stockholders. In February 2000, we entered into two letters of credit
for approximately $2.8 million and $198,000 to secure lease deposits to expand
into two new office facilities. These letters of credit expire in February
2001, and are secured by certificates of deposit in the same amounts.

   We believe that the net proceeds from this offering, combined with the
proceeds of the series D private placement, the proceeds of the private
placement to be closed contemporaneously with this offering, current

                                       24
<PAGE>

cash balances and borrowing capacity under our credit facilities will be
sufficient to fund our requirements for working capital and capital
expenditures for at least the next twelve months. Thereafter, we may sell
additional equity or debt securities or seek additional credit facilities.
Sales of additional equity or convertible debt securities would result in
additional dilution to our stockholders. We may need to raise additional funds
sooner in order to support expansion, develop new or enhanced services, respond
to competitive pressures, acquire complementary businesses or technologies or
take advantage of unanticipated opportunities. Our future liquidity and capital
requirements will depend upon numerous factors, including the success of our
existing and new service offerings and competing technological and market
developments. Additional financing, if any, may not be available on
satisfactory terms.

Disclosure About Market Risk

   Our exposure to market risk for changes in interest rates relates primarily
to the increase or decrease in the amount of interest income we can earn on our
available funds for investment and on the increase or decrease in the amount of
interest expense we must pay with respect to our various outstanding debt
instruments. The risk associated with fluctuating interest expense is limited,
however, to the exposure related to those debt instruments and credit
facilities that are tied to variable market rates. We do not plan to use
derivative financial instruments in our investment portfolio. We plan to ensure
the safety and preservation of our invested principal funds by limiting default
risks, market risk and reinvestment risk. We plan to mitigate default risk by
investing in high-credit quality securities.

   All of our revenues are realized currently in U.S. dollars and are from
customers primarily in the United States. Therefore, we do not believe that we
currently have any significant direct foreign currency exchange rate risk.

                                    BUSINESS

Overview

   We are a leading Internet professional services firm providing strategy,
technology, implementation and support services solutions to large corporations
and emerging Internet businesses that engage in e-commerce with other
businesses. We focus on helping our clients conceive and implement e-markets
and electronic customer relationship management systems. E-markets are
electronic marketplaces that enable businesses to collaborate with trading
partners, conduct e-commerce, manage distribution relationships and enhance
business partnerships. Electronic customer relationship management is an
Internet-based approach to coordinating a company's customer relationships
across communications channels, business functions and trading partners.

   We believe our capabilities are well-suited to developing the extremely
complex, highly integrated systems required for effective business-to-business
e-commerce solutions. Our professionals create scalable, reliable and
integrated business systems using our proprietary LightSpeed delivery model and
i2K architectural framework. We provide our services through our staff of 168
professionals, who have an average of ten years experience in business process
analysis, technology architecture, project management and software engineering.

Industry Background

   The Internet enables millions of businesses and consumers to share
information and conduct commerce electronically. Businesses initially used
their Internet sites primarily for advertising and promotional purposes. As
Internet usage increased, businesses realized the Internet could also be used
as an effective medium for directly targeting consumers, improving
communications with customers and generating business-to-consumer e-commerce
transactions. Forrester Research, Inc. estimates that the total value of goods
exchanged in the United States business-to-consumer e-commerce market will
exceed $100 billion by 2003. Driven by the scale and scope of this rapidly
emerging business opportunity, businesses began to develop increasingly
complex, higher transaction volume consumer-oriented websites.

   While business-to-consumer e-commerce was evolving, companies also began to
use Internet technology to streamline their internal operations and
electronically integrate select internal processes with other businesses,
including their suppliers, distributors and key business customers. Today,
businesses are using Internet technologies to improve their competitive
positions by increasing operating efficiencies, strengthening their trading
partner relationships and identifying and capitalizing on emerging business
opportunities by developing various Internet-based business models. Forrester
Research, Inc. estimates that the total value of goods exchanged in the United
States business-to-business e-commerce market will increase from $43.1 billion
in 1998 to $2.7 trillion in 2004, representing a 99% six-year compound annual
growth rate.

   An important emerging Internet-based business model is the electronic
market. Electronic markets provide Internet-based trading hubs where multiple
buyers and sellers communicate and conduct electronic commerce. The creation of
these e-markets enables innovative methods for trading between business
partners, including auctions, reverse auctions, aggregation, inventory
liquidation and on-line negotiation. These electronic markets provide
unprecedented global opportunities for businesses to exchange information and
execute transactions with the efficiency, cost effectiveness and global reach
provided by Internet technologies, while supporting individual contractual
relationships between trading partners. Examples of these e-markets include
autoExchange.com, ePolicy.com, Pure Markets, tradepac.com and VerticalNet.

   Businesses are rapidly developing e-markets and other business-to-business
e-commerce systems in order to fully realize the market opportunity. Business-
to-business e-commerce systems are engineered to facilitate:

  . significant increases in the value and complexity of data and
    transactions processed

  . improved performance and response times to support real-time access by
    trading partners from a variety of technology platforms

                                       26
<PAGE>

  . improved reliability, accuracy and security for transactions

  . high degrees of integration between legacy applications, networks and
    technology platforms within a company as well as across diverse
    businesses

  . the execution of a broad variety of processes and payment methods that
    exist between trading partners

   These business-to-business systems are highly complex and often involve a
greater number of steps per transaction and more processes than business-to-
consumer systems, creating a longer, more intricate commerce chain and
resulting in a more complex delivery infrastructure. Some of the typical
differences between business-to-consumer and business-to-business e-commerce
are highlighted below:

</TABLE>


   Developing and supporting business-to-business e-commerce systems requires
substantial expertise in designing new business processes that integrate with
existing operations, selecting and implementing the appropriate Internet
technologies and managing the implementation process to meet the time-to-market
needs characteristic of today's competitive business environment. There is a
limited supply of high-quality, experienced Internet services professionals,
and demand for these professionals is increasing rapidly. This makes it
increasingly difficult for companies seeking to internally implement business-
to-business e-commerce solutions to hire, develop and retain these
professionals. As a result, an increasing number of businesses, from start-ups
to Fortune 1000 companies, engage third-party Internet professional services
firms to help them design and implement business-to-business e-commerce
systems.

   The demand for these and related Internet and e-commerce services is
projected to grow dramatically. International Data Corporation estimates that
this market will grow from approximately $7.8 billion in 1998 to $78.6 billion
in 2003, representing a 59% compound annual growth rate.

                                       27

   We believe there are only a few Internet professional services firms with an
exclusive focus on business-to-business e-commerce engagements. Additionally,
we believe that in order to be successful in this market, Internet professional
services firms must possess an integrated model of business-to-business-
oriented process analysis, substantial software engineering expertise, strong
technology architecture and integration skills, and effective client and
project management capabilities.

Our Solution

   We are a leading Internet professional services firm. We provide business-
to-business e-commerce systems solutions to large corporations and emerging
Internet businesses and focus on building and supporting complex e-markets and
electronic customer relationship management solutions.

   The key elements of our solution are:

   Early and Exclusive Business-to-Business e-Commerce Focus. We have delivered
business-to-business software applications for our clients since 1995. We
provide our services through teams of talented professionals with extensive
experience in business process analysis, project management and software
engineering. We believe our early vision and business-to-business experience
enables us to rapidly and efficiently architect and implement Internet
solutions.

   Proprietary LightSpeed Delivery Model. LightSpeed, our proprietary
collection of operating principles, methods and frameworks, is an Internet-
based model for governing the way we interact with our clients, including how
we define, price, staff and manage our projects. We believe the successful
application of LightSpeed in our engagements enables us to more accurately
forecast project schedules and costs. LightSpeed also allows us to better
manage project risk and to identify, capture and reuse valuable Internet
frameworks, designs, processes and techniques that we have developed while
working on prior engagements.

   Proprietary i2K Architectural Model. i2K is a collection of principles,
methods and frameworks we have created to guide development of complex
e-commerce systems. Using i2K we help our clients to develop e-markets and
electronic customer relationship management systems that leverage and integrate
information between their Internet-based and legacy systems and those of their
trading partners. We believe the successful design and implementation of
projects using our i2K model result in secure, reliable systems and a highly
extendable architectural platform.

   Packaging of Services. Based on our extensive experience in business-to-
business e-markets and electronic customer relationship management solutions,
we have developed modular solutions tailored for discrete business processes.
Our packaged service offerings are comprised of three major elements: pre-
defined business functions, proven business practices and pre-defined
technology architecture. We believe packaging our services in this manner
reduces our project risk, increases our operating margins, improves our sales
force's productivity, speeds time-to-market for our clients and differentiates
us from our competition.

   Integrated End-to-End Implementation Capabilities. We believe we provide the
complete range of capabilities required to deliver comprehensive business-to-
business e-commerce solutions to our clients. Our core competencies range from
business process analysis and technology architecture to Internet application
development and post-launch managed web services.

   We believe our breadth of capabilities enables us to engineer and deliver
complete electronic markets and electronic customer relationship management
solutions for a fixed price and within fixed timeframes.

   Knowledge Management and Transfer. We collect, store and organize
information we acquire from interaction with our clients in order to enhance
our existing base of technology and business process expertise. Inside Inventa,
our corporate intranet, is a secure integrated knowledge management repository
that facilitates

                                       28
<PAGE>


the dissemination of this intellectual capital across our organization. In
addition, eTrack, our internal Internet-based project management system,
enables us to capture, monitor and manage information for project scheduling;
project status review; document and deliverable distribution to our
professionals and our clients; and detailed information on the resources
required to achieve specific tasks on a project. We believe this expanding base
of readily accessible knowledge enables us to meet our clients' ever-increasing
expectations for our performance, improves our ability to forecast the
estimated time and resources required to complete our client engagements and
increases the reusability of our intellectual capital, thereby reducing risks
to us and our clients.

Our Strategy

   Our objective is to enhance our position and reputation as a leading
provider of Internet professional services in the context of business-to-
business e-commerce. The key elements of our growth strategy are to:

   Maintain Our Exclusive Business-to-Business e-Commerce Focus. We intend to
maintain our exclusive focus on business-to-business e-commerce. We believe
this segment of the market is the most strategic to our clients, is the fastest
growing segment of the e-commerce market and is best aligned with our core
competencies. Currently, we target two major business-to-business e-commerce
practice areas:

  . e-markets, where we engineer and support business-to-business electronic
    markets that facilitate the timely exchange of information and goods
    between trading partners

  . electronic customer relationship management, where we deliver solutions
    for a broad range of business-to-business customer interaction processes,
    including sales, marketing and customer support

   We also intend to expand our service offerings by developing additional
practices to cover the full range of business-to-business e-commerce processes
and relationships in which our clients and prospective clients are likely to
engage, including electronic partner relationship management and electronic
supply chain management.

   Maintain Our Technology Leadership. We believe that our clients choose to
work with us because of our reputation for technology leadership and for
successfully solving some of the most challenging business-to-business e-
commerce problems with leading-edge Internet technologies. We believe working
on complex assignments will make us more attractive to high-quality
professionals, who enlarge our technology skill set and knowledge base. We
intend to maintain our technology leadership by:

  . pursuing complex engagements that allow us to refine and advance our
    business-to-business e-commerce capabilities

  . researching emerging technologies for their relevance and applicability
    to our clients' business strategies

  . refining and enhancing our proprietary i2K architectural model to take
    advantage of advances in Internet technology

  . deepening our current partner relationships and establishing new
    partnerships to maintain our status as an early adopter of emerging
    technologies and skill sets

  . enhancing our knowledge management infrastructure to improve the breadth,
    depth and quality of access to technology-related information by our
    professionals

   Continue to Package Our Services. We intend to continue to package our
services. We believe packaging our services:

  . permits faster and more predictable project implementations resulting in
    higher operating margins

                                       29
<PAGE>

  . facilitates marketing our services and solutions to prospective clients

  . demonstrates our thought leadership and competencies

  . improves training for our professional staff and increases sales force
    productivity

  . differentiates us from our competitors

   We intend to expand our packaged service offerings beyond our current eSales
and eCare products by leveraging knowledge and experience from our engagements,
continuing to refine and enhance our LightSpeed delivery model and identifying
and establishing the partner relationships relevant to effective packaging of
our services.

   Recruit and Retain Highly-Skilled Professionals. We intend to continue to
hire, train and retain individuals who are highly skilled in the engineering of
complex Internet systems and business processes . To provide an environment
conducive to recruitment and retention, we have created a corporate culture
that emphasizes balance between one's professional and personal life,
challenging work assignments, broad equity ownership, promotion from within,
opportunities for advanced training and direct involvement in growing our
business.

   Further, we have designed our LightSpeed delivery model to be a key employee
recruiting and retention tool by:

  . encouraging direct client contact at all levels of our project teams

  . basing our teams at our facilities to reduce professionals' travel time

  . conducting our engagements using small, highly-specialized project teams

   We will continue to expand our in-house recruiting staff and to invest in
initiatives focused on direct and Internet-based recruitment, employee referral
programs and on-campus recruiting. In addition, we intend to expand the
geographic reach of our recruitment efforts and to advertise and promote our
brand to generate awareness of our company among potential employees in
relevant markets.

   Expand Existing and Establish New Client Relationships. We believe our track
record of successful engagements has resulted in strong relationships with our
clients. As a result, our clients often request that we expand the scope and
complexity of our engagements. This reinforces our growing reputation as an
innovative provider of business-to-business e-commerce solutions. We intend to
leverage our reputation for client satisfaction and innovation to attract new
engagements with our existing clients and to capture new clients through
referral-driven sales.

   In addition, we intend to engage new clients by continuing to:

  . expand our direct sales force in our current geographic markets

  . invest in promotional activities designed to improve brand awareness and
    provide sales leads

  . establish new strategic business and technology alliances

  . expand geographically, both within the United States and internationally

Our Services

   We have developed a broad range of capabilities in designing and
implementing business-to-business e-commerce systems and applications for our
clients, from integrating demand-side Internet applications with front- and
back-office systems to supply-side Internet applications for servicing trading
partners. Our capabilities include:

  . competitive assessment of our clients' Internet strategies and
    capabilities

                                       30

  . technology architecture design and engineering

  . custom Internet application development

  . e-commerce software implementation

  . systems integration

  . enterprise application integration (within and between businesses)

  . applications management and enhancement

  . service productization

   We leverage these skill sets and our substantial expertise in two major
business-to-business e-commerce practice areas, e-markets and electronic
customer relationship management, as described below:

   Electronic Markets. We engineer and support business-to-business
marketplaces that are highly scalable and extendable to accommodate the rapid
growth that well-designed and well-marketed business-to-business systems are
likely to experience.

   Electronic Customer Relationship Management. We design and engineer
Internet-based systems and applications for a broad range of business-to-
business customer interaction processes, including sales, marketing, customer
support, distribution and fulfillment.

   These service offerings are comprehensive, scalable, extendable and secure,
thereby helping our clients ensure the quality and integrity of their
relationships with their business customers and other trading partners.
Although each of our solutions is uniquely engineered and customized to meet
the expectations of each of our clients, we design them using standard Internet
technologies and commercially available software to accelerate project delivery
and ease system maintenance.

   We deliver our solutions using the following service models:

   LightSpeed Delivery Model. LightSpeed is our proprietary Internet-based
model for governing the way we deliver solutions to our clients. Using
LightSpeed, we usually complete entire projects for our clients in five to six
months.

                                       31
<PAGE>

   LightSpeed is composed of four distinct stages:

 Innovate          Our professionals work closely with our clients' senior
                   executives to conduct a strategic assessment of their
                   competitive positioning in the Internet marketplace and
                   create a business and technology roadmap for the development
                   of a business-to-business solution. We then arrive at a
                   shared vision of our clients' business-to-business
                   initiative and explore potential software applications,
                   identify architectural issues and highlight potential
                   obstacles to success. Finally, we deliver an agreed-upon
                   business-to-business e-commerce roadmap for the development
                   of a solution.

                   functionality and business processes for their projects.
                   Using intensive workshops, storyboarding and prototyping
                   techniques, we deliver functional requirements, an
                   application prototype, architecture and technology
                   recommendations and a detailed plan for the LightSpeed
                   Create and Launch stage.

- -------------------------------------------------------------------------------
 Create and Launch We develop a detailed engineering design and create a
                   comprehensive quality assurance plan. We then implement our
                   solution in a series of progressively more functional
                   releases. With this approach, we deliver a production-
                   quality release with meaningful, business-relevant
                   functionality usually within ten weeks. The entire Create
                   and Launch stage typically takes between 16 and 24 weeks and
                   may include two or three releases.

 Enhance           We help our clients evaluate an individual project's success
                   before embarking on the next project or major phase. We
                   refine our most recent implementation and enhance the
                   application in response to changes in user requirements. We
                   also offer our clients opportunities to expand their
                   implementations with application enhancement and database
                   consulting services.

   i2K Architectural Model. i2K is our proprietary collection of principles,
methods and frameworks for business-to-business e-commerce solutions. It
provides a schematic for developing electronic markets and electronic customer
relationship management systems that are scalable, adaptable, integrated with
our clients' Internet-based and legacy systems and extendable outside their
enterprises to their trading partners' systems. We believe each of our clients'
competitive advantage is directly related to how quickly and how well they
leverage and integrate information within their Internet-based and legacy
systems and with those of their trading partners. Accessing and combining this
information in meaningful ways is essential to leveraging the potential of the
Internet.

   Packaged Service Offerings. We have combined our LightSpeed delivery model,
our i2K architectural model, commercially available software and the collective
knowledge of our professionals into packaged service offerings for specific
business processes. We currently have targeted two critical business processes
with these Internet offerings, sales through our eSales offering and customer
care through our eCare offering. With eSales and eCare, we can quickly assess
and analyze our clients' businesses and recommend a portfolio of applications,
develop an implementation strategy, define system requirements, design the
technology architecture, and then prototype, engineer and enhance the
solutions. Using eSales and eCare, we can rapidly deliver what we have
determined to be the most common functionality for business-to-business
customer relationship management processes.

   Upon implementation of eSales or eCare, our clients' and their trading
partners' sales or customer service representatives have access to a broad
variety of capabilities to facilitate interaction with, and satisfy the needs
of, their business customers. Some of the more common functionalities include:

  . customer profiling

  . sales or customer service workflow or process management

                                       32
<PAGE>

  . sales or customer service case management

  . custom database-driven views of customers, products, suppliers and orders

  . e-mail messaging

  . sales and customer care management reporting

  . integration with call center operations

   eSales enables our clients to generate revenue through Internet-based sales
channels; satisfy and retain customers through online order and sales
management; and streamline the purchasing process for their business
customers.

   eCare enables our clients to ensure consistent, high-quality customer
interaction; retain customers through personalized and responsive service;
reduce overhead and call center volume; and capture customer data.

Case Studies

<TABLE>
  <C> <S>
                                     The Problem
  ADP ADP recognized an opportunity to enhance and extend its service offerings
      to small business customers after seeing an increasing number of small
      businesses obtaining Internet access. In addition, their market was
      changing as new competitors arrived with other offerings. In order for
      ADP to compete, sustain its leadership position and protect its brand, it
      needed to deliver a digital offering for its customers. ADP believed the
      new offering should provide its customers a payroll choice model, improve
      the level and quality of customer service, and increase customer
      convenience and control. ADP required that the system provide unlimited
      access to its customers for entering payroll data and reduce the number
      of errors entered into payroll databases. Bringing the service to market
      quickly was critical, as was seamless integration with legacy payroll
      systems, application of complex payroll and taxation issues and security.

- -------------------------------------------------------------------------------
           Our Solution: Electronic Customer Relationship Management System
      Our solution, EasyPayNet, is an easy to use, fully functional Web-based
      payroll system that accesses ADP's wide range of services, including
      federal, state and local tax filing, direct deposit and 401(k) services.
      Moreover, access is available 24 hours a day, seven days a week through a
      secure global network. In the Innovate stage, our business analysts
      identified and prioritized the functional requirements for providing
      payroll services over the Internet to ADP customers. We provided ADP with
      insights and options on how to leverage Internet technologies to provide
      functionality to their customers that it could not with its existing
      systems. We prioritized the resulting functionality for progressive
      releases of the solution and described the expected customer experience
      in each one of these releases. In the Blueprint stage, our architects
      defined the requirements for the first release, identified and selected
      the architectural and technology components and developed an application
      prototype. We selected Oracle's Relational DBMS as the database on NT
      servers, integrated with legacy data from an IBM AS/-400 using Oracle
      replication services. We created custom application services adapters for
      replication from the AS/-400 platform. We then selected Active Software's
      ActiveWeb technology on a Microsoft IIS WebServer for application
      services. We created a user experience base using a combination of custom
      HTML and Java Servelets. In the Create and Launch stage, we completed the
      technical design of the application and data models and identified legacy
      system integration requirements. We developed, tested and deployed the
      first release of the application and then delivered a production support
      environment that includes application support and maintenance services.
      Since the first release, we have implemented incremental enhancements,
      installing changes based on customer feedback. In addition, we have
      improved the level and quality of the infrastructure, optimized
      application performance and created a framework for enabling the
      integration of ADP's trading partners. The project was delivered in time
      to meet ADP's expectations for sustaining its competitive position and
      expanding its offerings via a digital channel.

- -------------------------------------------------------------------------------
                                     The Benefits
      The increased flexibility that EasyPayNet provides meets the unique needs
      of ADP's small business customers and increases ADP's competitiveness by
      streamlining operations on the Internet. In addition to satisfying its
      current customers, ADP is selling the service to a new market of
      customers it could not previously serve. As a by-product of the solution,
      ADP re-evaluated all its existing business processes and expects to
      derive infrastructure efficiencies.

                                            The Problem
  Cadence Design   Cadence Design Systems is the leading vendor of engineering
      Systems      design software. Its Customer Support organization realized
                   it lacked value-added support services for its clients, a
                   result of its inability to access an enterprise-wide profile
                   of important customer information. Cadence needed an
                   effective, seamless and transparent integration of key
                   supply chain databases. Cadence wanted a single system to
                   provide all the services it required. Cadence wanted to
                   leverage its nonintegrated legacy information sources,
                   rather than engineer a completely new solution.

- -------------------------------------------------------------------------------
                     Our Solution: Electronic Customer Relationship Management
                                              System
                   Our Innovate stage with Cadence enabled evaluation of the
                   strengths and weaknesses of its existing service model and
                   resulted in an initial architecture that met expectations
                   for integration of the heterogeneous legacy systems. In our
                   Blueprint Stage, our architects developed requirements for a
                   global customer entitlement system and the framework for
                   data mining, extracting and integrating from the legacy
                   customer service systems. Cadence was presented a discovery
                   document with implementation and architectural roadmaps and
                   a functionality prioritization matrix. In our Create and
                   Launch Stage, our engineers developed the global customer
                   entitlement system using NetDynamics Application Server as
                   the core, Oracle as the back-end database server, Sun
                   Solaris as the implementation platform, and completely
                   customized the integration solution in HTML and Java. The
                   application also used Oracle's Data Replication services.
                   Our engineers developed several adapters to integrate
                   Cadence's legacy systems, with order processing
                   applications, the Scopus Call Tracking System and their
                   online technical support system. The entire project was
                   completed in 16 weeks.

                   The system now presents a global and accurate view of
                   customer service entitlements by customer and product.
                   Customer Service representatives are making better decisions
                   and customers are experiencing less frustration. Cadence
                   expects to earn additional revenue, to reduce its case load
</TABLE>           and to experience cost savings of approximately $720,000
                   annually.

                                         The Problem
  ePolicy.com Cal-Surance, Inc., a leading insurance broker based in Southern
              California, wanted to find a more effective and efficient way to
              sell and service commercial insurance for small businesses and
              professionals.

- -------------------------------------------------------------------------------
                               Our Solution: Electronic Market
              In our Innovate Stage, our analysts developed an Internet
              strategy, competitive analysis and solution portfolio for Cal-
              Surance. Our business analysts identified that the opportunity
              space for real-time online quoting and purchasing of insurance
              was tightly connected to the concept of progressive disclosure of
              information and the simplification of the quoting process. In our
              Blueprint Stage, our architects prioritized the application
              portfolio into three distinct development phases: customer,
              partner and internal interaction. Our engineers also designed the
              application framework: Microsoft Commerce Server on NT for the
              core, Oracle for the back-end database server, Sun Solaris for
              the application platform, TideStone's NT spreadsheet/matrix
              quoting engine, Active Server Pages for the presentation layer,
              Microsoft COM for back-end integration, CyberSource for debit and
              credit card payments and custom engineered adapters for legacy
              claims systems. Our architects proceeded to complete the customer
              facing system blueprint phase in three weeks, producing a
              functional requirements document, concept prototype, detailed
              project plan and a fixed-price, fixed-time guaranteed proposal.
              In our Create and Launch Stage, our engineers were required to
              perform significant customization on the components in order to
              meet the specifications and requirements defined in the
              blueprint. Two releases covered the seven life cycle customer
              states: prospecting, buying, insured, renewing, maintaining,
              canceling and formerly insured. The site's functionality was
              defined in three weeks. In three months, the first release was
              uploaded for testing and review, and the second release followed
              six weeks later.

              through a new digital channel. The electronic market was
              eventually spun off into a new company, ePolicy.com, a business-
              to-business Internet company that is creating a new way for

                                            The Problem
   Pure Markets    The equipment leasing industry has multiple layers of
                   intermediaries and complex product offerings, creating an
                   inefficient market. This inefficiency results in lost
                   opportunities and higher costs. Pure Markets wanted to
                   create an electronic market to enable lessees and lessors to
                   conduct leasing transactions more efficiently and
                   effectively.

- -------------------------------------------------------------------------------
                                  Our Solution: Electronic Market
                   Their electronic market, Pure Markets.com, empowers lessees
                   to easily and quickly structure their lease finance request,
                   to solicit bids from a greater number of lessors and to
                   identify and select the optimal bid (on features and cost)
                   through PureMarket's intelligent bid comparator. Lessors
                   benefit by expanding the breadth of their market, being able
                   to target transactions attractive to them, reducing
                   origination costs, and increasing the share of leasing as a
                   finance option. In the Innovate stage, we defined the
                   technical capability needed to transform Pure Markets'
                   vision into a business reality. We helped Pure Markets
                   define its requirements and presented it with an
                   implementable technology architecture. In the Blueprint
                   Stage, we conducted extensive interviews with Pure Markets'
                   employees to define and document the variety of leasing
                   structures our solution would have to accommodate, and to
                   develop processes, user interface, application functionality
                   and data management services that comprised the leasing
                   electronic market. This stage required substantial
                   interaction between our project team and Pure Markets'
                   representatives due to the complexity of the user
                   interfaces. At the conclusion of the Blueprint Stage, we
                   delivered a comprehensive functional specification, a
                   functionality prioritization matrix and a schedule for
                   release delivery. In the Create and Launch stage, we used
                   Oracle as the database system on a Sun Solaris platform,
                   ColdFusion as the application server on an NT platform and
                   completed the presentation layer in a combination of HTML,
                   Java and ColdFusion applets. Our rapid and thorough
                   Blueprint Stage greatly facilitated Pure Markets'
                   development of this highly complex application.

                                           The Benefits
                   Pure Markets benefited by being able to achieve a rapid
                   time-to-market for an electronic market, a new channel that
                   brings together lessees and lessors on the Internet. Lessees
                   now have the opportunity to easily request bids from a
                   larger population of lessors and to compare bids using a
                   normalizing analytical tool, thereby enabling faster,
</TABLE>           simpler and more effective decisions. Lessors have access to
                   a much larger market, with greater targeting precision and
                   lower origination costs.


Employees

   As of February 29, 2000, we had 245 employees. Of these employees, 168 were
consulting and services delivery professionals, and 77 were personnel
performing marketing, sales, human resources, finance, accounting, legal,
internal information systems and administrative functions, including 11
executives and 20 sales and marketing personnel. None of our employees is
represented by a labor union, and we consider our employee relations to be
excellent.

Competition

   The market for Internet professional services is intensely competitive. We
believe the principal competitive factors in our industry are reputation and
client satisfaction, the experience and skill levels of professionals, advanced
technical architecture and project management expertise, ability to predict
project cost and manage resource scheduling and ability to recruit and retain
professionals.

                                       37
<PAGE>

While we primarily use the fixed-price, fixed-time pricing model, most of our
competitors use both fixed-price and time and materials pricing models for
their projects. We are not aware of a trend toward either pricing model.

   Our competition falls into the following categories:

  . Internet professional services firms (such as Lante, Proxicom, Sapient,
    Scient, US Interactive and Viant)

  . information technology consulting and systems integration firms (such as
    Andersen Consulting, Cambridge Technology Partners and EDS)

  . services divisions of computer hardware and software vendors (such as IBM
    and Oracle)

  . web design firms (such as Modem Media. Poppe Tyson and Razorfish)

  . information technology strategy consulting firms (such as @McKinsey,
    Diamond Technology Partners and Mainspring)

  . in-house information technology departments of our current and potential
    clients


   Future competitors may offer services that provide significant performance,
price, creative or other advantages over those offered by us. Therefore, we
expect to face additional competition from new competitors.

Alliances

   We leverage our marketing and sales efforts through alliances with a number
of vendors of Internet technology. Our partners include Active Software, Art
Technology Group, BroadVision, Exodus Communications, Extricity Software,
Hewlett-Packard, Microsoft, Moai Technologies, Selectica, Silknet Software,
webMethods and Vitria. These partners may recommend our services to their
clients, provide us sales leads, deliver training for our professionals and
enable us to obtain advance access to their technologies.

Sales and Marketing

   Our sales efforts are targeted at corporate clients who are investing
significant resources in their business-to-business e-commerce strategies. Our
sales force generates leads through a combination of direct mail, targeted
events with industry thought leaders and cooperative marketing with our
alliance partners. We have sales offices in the metropolitan areas of San
Francisco, New York, Chicago and Washington, D.C.

   To augment our sales effort we also have a separate marketing department
focused on two key objectives:

  . building brand recognition at a national level to drive business growth
    and support our recruiting efforts

  . developing and cultivating leads for our sales force

   To achieve these objectives, we engage in market research, public relations
and advertising, participate in trade shows and conduct seminars. In addition,
we employ a communication strategy based on standards for our logo, corporate
identity, website and marketing materials.

   Our most significant recent marketing initiative occurred in January 2000,
when we committed $300,000 to become the leading sponsor of the Inventa
Everest Environmental Expedition. This expedition involves the most
comprehensive clean-up of debris from the high camps of Mount Everest planned
to date.

Intellectual Property Rights

   Our proprietary knowledge base and the other intellectual property rights
that we develop for our clients are an integral part of our business. Our
clients generally retain ownership of custom work product and we

Development of Our Business

   We were incorporated in California in 1988 as Inventa Corporation. From 1988
to 1994, we were a client-server technology-based, system services firm. We
formed our Malaysian subsidiary in 1994 to serve the Asian markets. During
1995, we began to focus on Internet applications for business and in 1996 began
to focus exclusively on Internet business applications. We established our New
York area office in 1997. We decided to close our Malaysian subsidiary in 1998,
as a result of the Asian economic crisis, which prevented us from successfully
developing our business in that region. During 1999, we established offices in
the Chicago and Washington, D.C. areas. We reincorporated in Delaware in March
2000.

Facilities

   Our principal executive offices are located in approximately 45,000 square
feet of leased office space in Redwood Shores, California. The lease for this
office space is for a term of seven years and expires in May 2007. We also have
offices in the metropolitan areas of New York, New York, Washington, D.C. and
Chicago, Illinois. We lease all of our facilities and consider these facilities
to be adequate for our needs for the foreseeable future.

Legal Proceedings

   We are not a party to any material legal proceedings.

(1) All options were granted under our 1993 Plan. Options granted under the
    plan vest over a four-year period with 25% vesting at the first anniversary
    date of the grant date and the remaining shares vesting in equal monthly
    installments over the next 36 months. The board retains sole discretion to
    modify the terms, including the price, of outstanding options.

(2) Amounts represent hypothetical gains that could be achieved for the
    respective options if exercised at the end of the option term. These gains
    are based on assumed rates of stock price appreciation of 5% and 10%
    compounded annually from the date of offer to their expiration date based
    upon an initial public offering price of $10.00 per share. These
    assumptions are not intended to forecast future appreciation of our stock
    price. The potential realizable value computation does not take into
    account federal or state income tax consequences of option exercises or
    sales of appreciated stock.

(3) Excludes options to purchase 865,000 shares of common stock at an exercise
    price of $0.15 per share granted to Mr. Lavanty on December 31, 1998, and

    per share, and the other 40,000 options granted on August 1, 1999, have an

Employee Benefit Plans

   1993 Stock Option Plan. Our 1993 Stock Option Plan provides for the issuance
to employees, directors and consultants of incentive stock options and non-
qualified stock options to purchase up to a total of 5,355,000 shares of our
common stock. Our board of directors or a committee designated by our board of
directors may serve as administrator of the 1993 Plan. As of February 29, 2000,
options issued under the 1993 Plan to purchase a total of 3,993,653 shares of
common stock at a weighted average exercise price of $1.81 were outstanding, of
which options to purchase 203,603 shares at a weighted average exercise price
of $0.15 were fully vested. As of February 29, 2000, we had 713,184 shares of
common stock available for future grant under this plan.

   The terms of options granted under the 1993 Plan are as determined by the
administrator, subject to the following:

  . the option price per share for any incentive stock option or non-
    qualified stock option may not be less than the fair value and 85% of the
    fair value, respectively, of the common stock on the date of the grant

  . if an incentive stock option or non-qualified stock option is granted to
    a person who owns more than 10% of the total combined voting power of all
    our classes of stock, the exercise price shall be not less than 110% of
    the fair value of the common stock on the date of the grant

  . the term of each stock option may not exceed ten years, and in the case
    of a person who owns more than 10% of the total combined voting power of
    all our classes of stock, the term of each stock option may not exceed
    five years

  . payment for the exercise of an option may be in cash or in shares of
    common stock already owned by the option holder for more than six months
    and which have a fair value equal to the exercise price of the option, by
    delivery of a properly executed exercise notice together with irrevocable
    instructions to a broker to promptly deliver to us the amount required to
    pay the exercise price, or by delivery of an irrevocable subscription
    agreement that irrevocably obligates the option holder to pay the
    aggregate exercise price not more than 12 months after the date of
    delivery of the subscription agreement

   The administrator has the power to determine the terms of the options
granted, including the exercise price. The board of directors may amend,
suspend or discontinue the 1993 Plan at any time, provided that any board
action may not affect any rights with respect to options previously granted
under the 1993 Plan.

   Options granted under the 1993 Plan are not transferable other than by will
or by the laws of descent or distribution, and each option may be exercised
during the lifetime of the optionee only by the optionee. Options granted under
the 1993 Plan must generally be exercised within three months of the optionee's
separation of service from us, but in no event later than the expiration of the
term of the option.

   Our 1993 Plan provides that in the event of our merger with or into another
corporation or a sale of substantially all of our assets, each option or right
shall be assumed or an equivalent option or right substituted by the successor
corporation. If the outstanding options or rights are not assumed or
substituted, the option or stock purchase right will immediately fully vest and
become exercisable. The 1993 Plan also provides that in the event of our
proposed dissolution or liquidation, our board of directors will notify
optionees at least 15 days prior to the proposed action and that the options
will terminate immediately prior to the completion of the proposed action.

   2000 Stock Plan. Our 2000 Stock Plan was approved by our board of directors
in February 2000. As of March 1, 2000, we had reserved a total of 7,000,000
shares of our common stock for issuance under the 2000 Stock Plan of which
7,000,000 shares were available for issuance. The 2000 Stock Plan provides for
the granting to our employees of incentive stock options within the meaning of
Section 422 of the United States tax code, and for the granting to employees,
including officers and directors, non-employee directors and consultants, of
non-statutory stock options and stock purchase rights. Unless terminated
sooner, the 2000 Stock Plan will terminate automatically in 2010.

                                       47
<PAGE>

   Our 2000 Stock Plan is administered by our board of directors. Our board of
directors determines the terms of the options or stock purchase rights granted,
including the exercise price, the number of shares subject to each option or
stock purchase right, the vesting and the form of consideration payable upon
exercise. In addition, the board of directors has the authority to amend,
suspend or terminate the 2000 Stock Plan, provided that no board action may
affect any share of common stock previously issued and sold or any option
previously granted and then outstanding under the 2000 Stock Plan. Our board of
directors has the exclusive authority to interpret and apply the provisions of
the 2000 Stock Plan.

   Options and stock purchase rights granted under our 2000 Stock Plan are not
generally transferable by the optionee, and each option and stock purchase
right is exercisable during the lifetime of the optionee only by the optionee.
Options granted under the 2000 Stock Plan must generally be exercised within
three months of the end of the optionee's status as our employee or consultant
or within twelve months after his or her termination by death or disability,
but in no event later than the expiration of the option's ten year term. In the
case of stock purchase rights, unless the board of directors determines
otherwise, the agreement evidencing the grant shall provide that we have a
repurchase option exercisable upon the voluntary or involuntary termination of
his or her employment for any reason, including death or disability. In this
event, the purchase price per share will be equal to the original price and may
be paid by cancellation of his or her outstanding indebtedness to us, if any.
Our repurchase option shall lapse at a rate determined by the board of
directors. The exercise price of any incentive stock options granted under the
2000 Stock Plan and any non-statutory stock options intended to qualify as
"performance-based compensation" within the meaning of Section 162(m) of the
United States tax code must be at least equal to the fair value of our common
stock on the date of grant. With respect to any participant who owns stock
possessing more than 10% of the voting power of all classes of our outstanding
capital stock, the exercise price of any incentive stock option granted must
equal at least 110% of the fair value on the grant date, and the term of this
incentive stock option must not exceed five years. The term of all other
options granted under the 2000 Stock Plan may not exceed ten years.

   Our 2000 Stock Plan provides that in the event of our merger with or into
another corporation or a sale of substantially all of our assets, each option
or right shall be assumed or an equivalent option or right substituted by the
successor corporation. If the outstanding options or rights are not assumed or
substituted, the option or stock purchase right will immediately fully vest and
become exercisable.

   2000 Employee Stock Purchase Plan Our 2000 Employee Stock Purchase Plan was
adopted by our board of directors in March 2000. A total of 500,000 shares of
common stock have been reserved for issuance under our 2000 Employee Stock
Purchase Plan, plus annual increases equal to the lesser of 1,500,000 shares,
or 5.0% of the outstanding shares on the determination date set by our board of
directors, or a lesser amount determined by our board of directors.

   Our 2000 Employee Stock Purchase Plan, which is intended to qualify under
Section 423 of the United States tax code, contains consecutive six month
offering and purchase periods. The offering periods generally start on the
first trading day on or after May 1 and ends on November 1 of each year, except
for the first offering period, which commences on the first trading day on or
after the effective date of this offering and ends on the last trading day on
or before April 30, 2003.

   Employees are eligible to participate if they are employed by us or any
participating subsidiary for at least 20 hours per week and more than five
months in any calendar year. However, any employee who immediately after grant
owns 5% or more of the total combined voting power of all classes of our
capital stock, or whose rights to purchase stock under all of our employee
stock purchase plans accrues at a rate which exceeds $25,000 worth of stock for
each calendar year may not be granted an option to purchase stock under this
plan. The 2000 Employee Stock Purchase Plan permits participants to purchase
common stock through payroll deductions of up to 10% of the participant's
compensation. Compensation is defined as the participant's base straight time
gross earnings and commissions but is exclusive of payments for overtime, shift
premium

                                       48
<PAGE>

payments, incentive compensation, incentive payments, bonuses and other
compensation. The maximum number of shares a participant may purchase during a
single purchase period is 5,000 shares.

   Amounts deducted and accumulated by the participant are used to purchase
shares of common stock at the end of each purchase period. The price of stock
purchased under the 2000 Employee Stock Purchase Plan is generally 85% of the
lower of the fair value of the common stock at the beginning of the offering
period or at the end of the purchase period. Participants may end their
participation at any time during an offering period, and they will be paid
their payroll deductions to date. Participation ends automatically upon
termination of employment with us.

   Rights granted under the 2000 Employee Stock Purchase Plan are not
transferable by a participant other than by will, the laws of descent and
distribution, or as otherwise provided under the plan. The 2000 Employee Stock
Purchase Plan provides that, in the event of our merger with or into another
corporation or a sale of substantially all our assets, each outstanding option
may be assumed or substituted for by the successor corporation. If the
successor corporation refuses to assume or substitute for the outstanding
options, the offering period then in progress will be shortened and a new
exercise date will be set. The 2000 Employee Stock Purchase Plan will terminate
automatically in 2010, unless terminated earlier. Our board of directors has
the authority to amend or terminate the purchase plan, except that no board
action may adversely affect any outstanding rights to purchase stock under the
2000 Employee Stock Purchase Plan. Our board of directors has the exclusive
authority to interpret and apply the provisions of the 2000 Employee Stock
Purchase Plan.

   401(k) Plan. We have a 401(k) savings plan that provides a tax-qualified
employee savings plan for our eligible employees. An employee may elect to
reduce his or her current annual compensation on a pre-tax basis and to have
the amount of the reduction contributed to the 401(k) savings plan. Subject to
the restrictions imposed by the United States tax code on highly compensated
employees, an employee may generally defer up to 25% of his or her pre-tax
earnings or the statutorily prescribed limit, which was $10,000 in calendar
year 1999. Our 401(k) savings plan is intended to qualify under Section 401(k)
of the United States tax code so that contributions by our employees to our
401(k) savings plan and income earned on plan contributions are not taxable to
employees until withdrawn from the 401(k) savings plan. The 401(k) savings plan
permits, but does not require, additional matching contributions by us on
behalf of all participants in the 401(k) savings plan.

   Life Insurance Program. We maintain a $2 million key man life insurance
policy on Ashok Santhanam, our Chairman of the Board of Directors, payable to
us in the event of Mr. Santhanam's death. We also maintain a $1 million key man
life insurance policy on David A. Lavanty, our President and Chief Executive
Officer, payable to us in the event of Mr. Lavanty's death.

                          DESCRIPTION OF CAPITAL STOCK

General

   Our amended and restated certificate of incorporation authorizes the
issuance of up to 25,000,000 shares of common stock, par value $0.001 per
share, and 14,779,511 shares of preferred stock, par value $0.001 per share,
the rights and preferences of which may be established from time to time by our
board of directors. As of February 29, 2000, there were outstanding 6,498,163
shares of common stock, and 14,615,511 shares of preferred stock, which are
convertible into 14,615,511 shares of common stock upon the completion of this
offering, were issued and outstanding. As of February 29, 2000, we had 70
holders of record of our common stock and 30 holders of record of our preferred
stock.

Common Stock

   Each holder of our common stock is entitled to one vote for each share held
of record on all matters to be voted upon by the stockholders. There are no
cumulative voting rights. Subject to the preferences of preferred stock issued
after the sale of the common stock in this offering, holders of common stock
are entitled to receive ratably any dividends that may be declared from time to
time by the board of directors out of funds legally available for that purpose.
In the event of our liquidation, dissolution or winding up, holders of common
stock would be entitled to share in our assets remaining after the payment of
liabilities and the satisfaction of any liquidation preference granted to the
holders of any outstanding shares of preferred stock. Holders of common stock
have no preemptive or conversion rights or other subscription rights, and there
are no redemption or sinking fund provisions applicable to the common stock.
All outstanding shares of common stock, the shares of common stock to be issued
upon conversion of the outstanding preferred stock, the shares of common stock
to be issued in the contemporaneous private placement and the shares of common
stock offered by us in this offering, when issued and paid for, will be fully
paid and nonassessable. The rights, preferences and privileges of the holders
of common stock are subject to, and may be adversely affected by, the rights of
the holders of shares of any series of preferred stock that we may designate in
the future.

Preferred Stock

   Upon the completion of this offering, the board of directors will be
authorized, subject to any limitations prescribed by law, without stockholder
approval, from time to time to issue up to an aggregate of 14,779,511 million
shares of preferred stock, par value $0.001 per share, in one or more series,
with each series to have rights and preferences, including voting rights,
dividend rights, conversion rights, redemption privileges and liquidation
preferences, as shall be determined by the board of directors. The rights of
the holders of common stock will be subject to, and may be adversely affected
by, the rights of holders of any series of preferred stock that may be issued
in the future. Any issuance of preferred stock, while providing desirable
flexibility in connection with possible acquisitions and other corporate
purposes, could have the effect of making it more difficult for a third party
to acquire, or of discouraging a third party from attempting to acquire, a
majority of our outstanding voting stock. We currently have no plans to issue
any shares of preferred stock.

Warrants

   As of February 29, 2000, we had outstanding warrants to purchase 160,000
shares of series C preferred stock at an exercise price of $2.50 per share.
These warrants are exercisable for 160,000 shares of common stock upon the
completion of this offering. Each warrant has a net exercise provision under
which the holder may, in lieu of payment of the exercise price in cash,
surrender the warrant and receive a net amount of shares, based on the fair
value of our stock at the time of the exercise of the warrant, after deducting
the aggregate exercise price. The warrants for 160,000 shares of series C
preferred stock will expire on November 30, 2004.

Limitation of Liability and Indemnification Matters

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

  . breach of their duty of loyalty to the corporation or its stockholders

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

  . unlawful payments of dividends or unlawful stock repurchases or
    redemptions

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

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

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

   We have obtained directors and officers' insurance providing indemnification
for all of our directors and officers. Prior to the completion of this
offering, we will enter into agreements to indemnify our directors and
executive officers, in addition to the indemnification provided for in our
bylaws. These agreements, among other things, will indemnify our directors and
executive officers for certain expenses, including attorneys' fees, judgments,
fines and settlement amounts incurred by any such person in any action or
proceeding, out of such person's services as a director, officer, employee,
agent or fiduciary of ours, any subsidiary of ours or any other company or
enterprise to which the person provides services at our request. We believe
that these provisions and agreements are necessary to attract and retain
qualified persons as directors and executive officers.

   At present, there is no litigation or proceeding involving any of our
directors or officers in which indemnification is required or permitted, and we
are not aware of any threatened litigation or proceeding that may result in a
claim for indemnification.

Registration Rights

   The holders of 14,615,511 shares of preferred stock and 1,350,000 shares of
common stock issued in connection with the acquisition of XTEND-Tech have been
granted rights to require us to register their shares under the Securities Act
provided under the terms of an investors' registration rights agreement between
the holders of our securities and us. Beginning as soon as practicable after
January 1, 2000, holders of at least 50% of the covered securities may require
on up to two occasions that we register for public resale all or a lesser
amount of their securities. We need not register these shares if the requested
registration would occur after we have effected two registrations, or if the
requested registration would occur within 180 days following the effective date
of any Form S-1 registration statement we have filed. Also, we may defer the
registration of the shares for up to 90 days if, in the good faith judgment of
the board of directors, it would be seriously detrimental to our stockholders
and us for the registration statement to be filed.

   In addition, holders of our securities who are parties to the agreement may
require on up to four occasions, but only once in any 12-month period that we
register their shares for public resale on a Form S-3 registration statement;
provided that

  .  we are eligible to use Form S-3 and the value of the securities to be
     included is at least $500,000

                                       54
<PAGE>

  .  the request for Form S-3 registration does not occur within 180 days
     following the effective date of any registration statement registering
     shares of common stock

  .  the request for Form S-3 registration does not occur within 180 days
     following the effective date of a registration statement registering
     securities required to be registered by the holders of at least 50% of
     the outstanding securities

  We are not required to maintain the effectiveness of any Form S-3 for more
than 180 days from the effective date of the Form S-3. In view of market
conditions, we may reduce the number of securities to be registered on Form S-3
to not less than 50% of the shares the holders of registrable securities have
requested to be registered. Furthermore, in the event we elect to register any
of our shares of common stock for the purposes of effecting any public offering
other than our initial public offering, the holders of securities who are
parties to the agreement are entitled to include their shares of common stock
in the registration, but in view of market conditions, we may reduce the number
of shares proposed to be registered. All expenses in connection with any
registration will be borne by us.

Antitakeover Provisions

   The provisions of our amended and restated certificate of incorporation and
bylaws may have the effect of making it more difficult for a third party to
acquire, or of discouraging a third party from attempting to acquire, control
of us. Such provisions could limit the price that investors might be willing to
pay in the future for shares of our common stock. These provisions allow us to
issue preferred stock without any vote or further action by the stockholders,
eliminate the right of stockholders to act by written consent without a meeting
and eliminate cumulative voting in the election of directors. These provisions
may make it more difficult for stockholders to delay or prevent a change in
control of us.

   We are subject to Section 203 of the Delaware General Corporation Law, which
regulates corporate acquisitions. In general, Section 203 prohibits a publicly
held Delaware corporation from engaging in a business combination with an
interested stockholder for a period of three years following the date the
person became an interested stockholder, unless:

  . the board of directors approved the transaction in which such stockholder
    became an interested stockholder prior to the date the interested
    stockholder attained such status

  . upon consummation of the transaction that resulted in the stockholder's
    becoming an interested stockholder, he or she owned at least 85% of the
    voting stock of the corporation outstanding at the time the transaction
    commenced, excluding shares owned by persons who are directors and also
    officers

  . the business combination is approved by a majority of the board of
    directors and by the affirmative vote of at least two-thirds of the
    outstanding voting stock that is not owned by the interested stockholder

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

   Our amended and restated certificate of incorporation provides that, upon
the completion of this offering, the board of directors will be divided into
three classes of directors with each class serving a staggered three-year term.
The classification system of electing directors may tend to discourage a third
party from making a tender offer or otherwise attempting to obtain control of
us and may maintain the incumbency of the board of directors, as the
classification of the board of directors generally increases the difficulty of
replacing a majority of the directors. Our amended and restated certificate of
incorporation eliminates the right of stockholders to act by written consent
without a meeting, and our bylaws eliminate the right of stockholders to call
special meetings of stockholders. The authorization of undesignated preferred
stock makes it possible for the board of

                                       55
<PAGE>

directors to issue preferred stock with voting or other rights or preferences
that could impede the success of any attempt to change control of us. These
provisions may have the effect of deferring hostile takeovers or delaying
changes in control of our management. The amendment of any of these provisions
would require approval by holders of at least 66 2/3% of the outstanding common
stock.

Transfer Agent and Registrar

   The transfer agent and registrar for our common stock is First Union
National Bank.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Prior to this offering, there has been no market for our common stock.
Future sales of substantial amounts of common stock in the public market
following this offering could cause the prevailing market price of our common
stock to fall and impede our ability to raise equity capital at a time and on
terms favorable to us.

   Upon completion of this offering, we will have outstanding an aggregate of
25,196,929 shares of common stock, assuming no exercise of the underwriters'
over-allotment option and no exercise of outstanding options or outstanding
warrants after February 29, 2000. Of these outstanding shares, the 3,500,000
shares sold in this offering will be freely tradable without restriction or
further registration under the Securities Act, unless purchased by our
"affiliates" as that term is defined in Rule 144 under the Securities Act. The
remaining 21,696,929 shares of common stock outstanding upon completion of the
offering and held by existing stockholders will be "restricted securities" as
that term is defined in Rule 144 under the Securities Act. Restricted shares
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 promulgated under
the Securities Act, which rules are summarized below, or another exemption.
Sales of the restricted shares in the public market, or the availability of
such shares for sale, could adversely affect the market price of our common
stock. We, our executive officers and directors and stockholders who hold of
more than 100,000 shares of our common stock have entered into contractual
lock-up agreements, providing that they will not offer, sell, contract to sell
or grant any option to purchase or otherwise dispose of shares of common stock
owned by them or that could be purchased by them through the exercise of
options or warrants for a period of 180 days after the date of this prospectus
without the prior written consent of Lehman Brothers Inc. As a result of these
contractual restrictions, notwithstanding possible earlier eligibility for sale
under the provisions of Rules 144, 144(k) and 701, additional shares will be
eligible for sale beginning 181 days after the effective date of the offering,
subject in some cases to volume limitations.

     More Than 180 Days After Effective Date..................  3,178,936 Shares
</TABLE>

   In general, under Rule 144 as currently in effect, beginning 91 days after
the date of this prospectus, a person, or persons whose shares are aggregated,
who has beneficially owned restricted shares for at least one year, including
persons who may be deemed to be our affiliates, would be entitled to sell
within any three-month period a number of shares that does not exceed the
greater of:

 . 1% of the number of shares of common stock then outstanding, which will
   equal approximately 251,969 shares immediately after the offering

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

   Sales under Rule 144 are also subject to manner of sale provisions and
notice requirements and to the availability of current public information about
us. Under Rule 144(k), a person who is not deemed to have been our affiliate at
any time during the 90 days preceding a sale and who has beneficially owned for
at least two years the restricted shares proposed to be sold, including the
holding period of any prior owner except an affiliate, is entitled to sell such
shares without complying with the manner of sale, public information, volume
limitation or notice provisions of Rule 144.

   Subject to limitations on the aggregate offering price of a transaction and
other conditions, Rule 701 permits resales of shares issued prior to the date
the issuer becomes subject to the reporting requirements of the Securities
Exchange Act of 1934, pursuant to compensatory stock or option plans or
contracts commencing 90 days after the issuer becomes subject to the reporting
requirements of the Exchange Act, in reliance upon

                                       57
<PAGE>


Rule 144 but without compliance with the holding period requirements and other
restrictions. In addition, the Commission has indicated that Rule 701 will
apply to typical stock options granted by an issuer before it becomes subject
to the reporting requirements of the Exchange Act, along with the shares
acquired upon exercise of such options, including exercises after the date the
issuer becomes so subject. Securities issued in reliance on Rule 701 are
restricted securities and, subject to the contractual restrictions described
above, beginning 91 days after the date of this prospectus, may be sold by
persons other than affiliates subject only to the manner of sale provisions of
Rule 144 and by affiliates under Rule 144 without compliance with its one-year
minimum holding period requirements.

   We, our executive officers and directors and stockholders who hold more than
100,000 shares of our stock have agreed not to sell or otherwise dispose of any
shares of common stock or any securities convertible into or exercisable or
exchangeable for common stock, or enter into any swap or similar agreement that
transfers, in whole or in part, the economic risk of ownership of the common
stock, for a period of 180 days after the date of this prospectus, without the
prior written consent of Lehman Brothers Inc., subject to limited exceptions.

   We intend to file a registration statement under the Securities Act covering
the shares of common stock subject to outstanding options or reserved for
issuance under the 1993 Plan. This registration statement is expected to be
filed within 90 days of effectiveness of the registration statement covering
the shares of common stock in this offering and will automatically become
effective upon filing. Accordingly, shares registered under that registration
statement will, subject to Rule 144 volume limitations applicable to affiliates
and the expiration of a 180-day lock-up period, be available for sale in the
open market, except to the extent that the shares are subject to our vesting
restrictions or the contractual restrictions described above.

   The underwriting agreement provides that the underwriters' obligations to
purchase shares of common stock depend on the satisfaction of the conditions
contained in the underwriting agreement, and that if any of the shares of
common stock are purchased by the underwriters under the underwriting
agreement, then all of the shares of common stock that the underwriters have
agreed to purchase under the underwriting agreement must be purchased. The
conditions contained in the underwriting agreement include the requirement that
the representations and warranties made by us to the underwriters are true,
that there is no material change in the financial markets and that we deliver
to the underwriters customary closing documents.

   The following table shows the per share and total underwriting discounts and
commissions to be paid to the underwriters by us. These amounts are shown
assuming both no exercise and full exercise of the underwriters' option to
purchase 525,000 additional shares described below.

   The representatives have advised us that the underwriters propose to offer
the shares of common stock directly to the public at the initial public
offering price set forth on the cover page of this prospectus, and to dealers,
who may include the underwriters, at the initial public offering price less a
selling 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 brokers and dealers. After the offering, the underwriters may change
the offering price and other selling terms.

                                       59

   We have granted to the underwriters an option to purchase up to an aggregate
of 525,000 additional shares of common stock, exercisable solely to cover over-
allotments, if any, at the initial public offering price less the underwriting
discounts and commissions shown on the cover page of this prospectus. The
underwriters may exercise this option at any time until 30 days after the date
of the underwriting agreement. If this option is exercised, each underwriter
will be committed, so long as the conditions of the underwriting agreement are
satisfied, to purchase a number of additional shares of common stock
proportionate to the underwriter's initial commitment as indicated in the
preceding table, and we will be obligated under the over-allotment option to
sell the shares of common stock to the underwriters.

   We, our executive officers and directors and stockholders who hold more than
100,000 shares of our stock have agreed not to directly or indirectly do any of
the following, whether any transaction described in clause (1) or (2) below is
to be settled by delivery of common stock or other securities, in cash or
otherwise, in each case without the prior written consent of Lehman Brothers
Inc. on behalf of the underwriters, for a period of 180 days after the date of

      common stock or substantially similar securities, other than the grant
      of options under option plans existing on the date hereof

   Prior to the offering, there has been no public market for the shares of our
common stock. The initial public offering price will be negotiated between the
representatives and us. In determining the initial public offering price of the
common stock, the representatives will consider, among other things and in
addition to prevailing market conditions, our historical performance and
capital structure, estimates of our business potential and earnings prospects,
an overall assessment of our management and the consideration of the above
factors in relation to market valuation of companies in related businesses.

   We have applied for quotation of our common stock on the Nasdaq National
Market under the symbol "INVA."

   We have agreed to indemnify the underwriters against liabilities, including
liabilities under the Securities Act and liabilities arising from breaches of
the representations and warranties contained in the underwriting agreement, and
to contribute to payments that the underwriters may be required to make for
these liabilities.

   We estimate that the total expenses of the offering, excluding underwriting
discounts and commissions, will be approximately $1,560,000.

   Until the distribution of the common stock is completed, rules of the
Commission may limit the ability of the underwriters and selling group members
to bid for and purchase shares of common stock. As an exception to these rules,
the representatives are permitted to engage in transactions that stabilize the
price of the common stock. These transactions may consist of bids or purchases
for the purpose of pegging, fixing or maintaining the price of the common
stock.

   The underwriters may create a short position in the common stock in
connection with the offering, which means that they may sell more shares than
are set forth on the cover page of this prospectus. If the underwriters create
a short position, then the representatives may reduce that short position by
purchasing common stock in the open market. The representatives also may elect
to reduce any short position by exercising all or part of the over-allotment
option.

   The underwriters have informed us that they do not intend to confirm sales
to discretionary accounts that exceed five percent of the total number of
shares of common stock offered by them.

   The representatives also may impose a penalty bid on underwriters and
selling group members. This means that if the representatives purchase shares
of common stock in the open market to reduce the underwriters' short position
or to stabilize the price of the common stock, they may reclaim the amount of
the selling concession from the underwriters and selling group members who sold
those shares as part of the offering.

   In general, purchases of a security for the purpose of stabilization or to
reduce a syndicate short position could cause the price of the security to be
higher than it might otherwise be in the absence of those purchases. The
imposition of a penalty bid might have an effect on the price of a security to
the extent that it was to discourage resales of the security by purchasers in
an offering.

   Neither we nor any of the underwriters make any representation or prediction
as to the direction or magnitude of any effect that the transactions described
above may have on the price of the common stock. In addition, neither we nor
any of the underwriters make any representation that the representatives will
engage in these transactions or that these transactions, once commenced, will
not be discontinued without notice.

   Any offers in Canada will be made only under an exemption from the
requirements to file a prospectus in the relevant province of Canada where the
sale is made.

   At our request, the underwriters have reserved up to 12% of the shares of
the common stock offered by this prospectus for sale to our directors, prior
investors and other persons associated with Inventa at the initial public
offering price set forth on the cover page of this prospectus. These persons
must commit to purchase no later than the close of business on the day
following the date of this prospectus. The number of shares available for sale
to the general public will be reduced to the extent these persons purchase the
reserved shares.

Corporation, will be facilitating a portion of the electronic distribution of

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and

 Stockholders of Inventa Technologies, Inc.

   In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations and comprehensive losses, of
stockholders' equity (deficit) and of cash flows present fairly, in all
material respects, the financial position of Inventa Technologies, Inc. and its
subsidiary (the "Company") at December 31, 1997, 1998 and 1999, and the results
of its operations and its cash flows for the years ended December 31, 1997,
1998 and 1999, in conformity with accounting principles generally accepted in
the United States. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with auditing standards generally accepted in the
United States, which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

 The Company

   Inventa Corporation (the "Company") was incorporated in California on
October 26, 1988. The Company reincorporated in Delaware as Inventa
Technologies, Inc. on March 23, 2000 (unaudited). The Company provides Internet
professional services including business-to-business e-commerce solutions to
companies located primarily in the United States. The Company architects,
engineers, integrates and supports complex business to business electronic
markets and electronic customer relationship management systems. E-markets are
electronic marketplaces that enable businesses to collaborate with trading
partners, conduct e-commerce, manage distribution relationships and enhance
business partnerships. Electronic customer relationship management is an
Internet based approach to coordinating a company's customer relationships
across communications channels, business functions and trading partners.

 Basis of Presentation

   The accompanying consolidated financial statements include the financial
statements of the Company and its wholly owned foreign subsidiary, ICG Systems
SDN. BHD, located in Malaysia through December 31, 1998. All intercompany
accounts between the Company and its wholly owned subsidiary have been
eliminated in consolidation.

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

 Revenue Recognition

   The Company derives its revenues from professional services which are
generally provided to clients on either a fixed-price or a time and materials
basis. Revenue from fixed-price engagements is recognized using the percentage
of completion method (based on the ratio of costs incurred to the total
estimated project costs). Revenue from time and materials engagements is
recognized as services are rendered. Payments received in advance of services
rendered are recorded as deferred revenue. The Company reports revenue net of
reimbursable expenses which are billed to and collected from clients.

   Provisions for estimated losses on uncompleted contracts are made on a
contract by contract basis and are recognized in the period in which such
losses become probable and can be reasonably estimated. To date, such losses
have not been significant.

   Client billings are generated upon achievement of milestones defined in the
engagement contracts. At December 31, 1997, 1998 and 1999, the Company had
$33,000, $32,000 and $1,183,000 in unbilled accounts receivable relating to
revenue recognized but not billed due to timing of milestone achievement.
Unbilled accounts receivable is included in prepaid expenses and other current
assets on the consolidated balance sheet.

 Cash and Cash Equivalents

   The Company considers all highly liquid instruments with an original
maturity of three months or less to be cash equivalents. Cash equivalents
consist primarily of deposits in money market funds.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)


 Concentration of Credit Risks

   Financial instruments that potentially subject the Company to a
concentration credit risk consist primarily of cash and cash equivalents and
accounts receivable. The Company limits its exposure to credit loss by placing
its cash and cash equivalents with high quality financial institutions. The
Company's accounts receivable are derived from revenue earned from clients
located in the United States. The Company performs ongoing credit evaluations
of its clients and maintains an allowance for potential credit losses based
upon the expected collectability of accounts receivable.

   The following table summarizes the revenues from clients in excess of 10% of
total revenues:

   Company E...................................................  18%     5%   --
   Company F...................................................  15%    --    --
</TABLE>

   At December 31, 1997, Company E and F accounted for 15% and 17% of total
accounts receivable, respectively. At December 31, 1998, Company A and D
accounted for 38% and 27% of total accounts receivable, respectively. At
December 31, 1999, Company A and B accounted for 26% and 25% of total accounts
receivable, respectively.

 Fair Value of Financial Instruments

   The Company's financial instruments, including cash and cash equivalents,
accounts receivable, short-term borrowings and accounts payable are carried at
cost, which approximates their fair value because of the short-term maturity of
these instruments. The carrying value of the Company's capital leases
approximate fair value because the implicit rates for these leases approximates
prevailing market rates. The fair value of long-term borrowings are estimated
based on current interest rates available to the Company for debt instruments
with similar terms, degrees of risk, and remaining maturities. The carrying
values of these obligations approximate their fair values.

 Property and Equipment

   Property and equipment are stated at cost. Depreciation is calculated using
the straight-line method over the estimated useful lives of the assets,
generally ranging from three to five years. Equipment acquired under capital
leases is amortized on a straight-line basis over the term of the lease or
estimated useful lives, whichever is shorter. Leasehold improvements are
amortized over the shorter of the term of the lease or the life of the asset.

 Long-lived Assets

   The Company evaluates the recoverability of its long-lived assets in
accordance with Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to be disposed of" ("SFAS No. 121"). SFAS No. 121 requires recognition of
impairment of long-lived assets in the event the net book value of such assets
exceeds the future undiscounted cash flows attributable to such assets. In that
event, a loss is recognized based on the amount by which the carrying value

                                      F-8
<PAGE>


                        INVENTA TECHNOLOGIES, INC.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

exceeds the fair value of the long-lived asset. Fair value is determined
primarily using the anticipated cash flows discounted at a rate commensurate
with the risk involved. Losses on long-lived assets to be disposed of are
determined in a similar manner, except that fair values are reduced for the
cost of disposal. No losses from impairment have been recognized in the
financial statements.

 Advertising

   Advertising is expensed as incurred. Advertising and public relations
expenses for the years ended December 31, 1997, 1998 and 1999, totaled $91,000,
$230,000 and $386,000, respectively.

 Stock-based Compensation

   The Company accounts for stock-based compensation in accordance with the
provisions of Accounting Principles Board Opinion No. 25 "Accounting for Stock
Issued to Employees," ("APB No. 25") and complies with the disclosure
provisions of Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation" ("SFAS No. 123"). Under APB No. 25, compensation
expense is recognized based on the difference, if any, on the date of grant
between the fair value of the Company's stock and the amount an employee must
pay to acquire the stock. The compensation expense is recognized over the
periods the employee performs the related services, generally the vesting
period of four years, consistent with the multiple option method described in
FASB Interpretation No. 28 ("FIN 28"). Use of this method resulted in
amortization of the deferred compensation at a rate of approximately 60%, 25%,
12%, and 3% over the respective four year period.

   The Company accounts for equity instruments issued to non-employees in
accordance with the provisions of SFAS No. 123 and the Emerging Issues Task
Force in Issue No. 96-18, "Accounting for Equity Instruments That Are Issued to
Other Than Employees for Acquiring, or In Conjunction with Selling, Goods or
Services" which require that such equity instruments are recorded at their fair
value on the measurement date, which is typically the date of grant.

 Net Loss Per Share

   Net loss per share is calculated in accordance with Statement of Financial
Accounting Standards No. 128, "Earnings per Share" (SFAS "No. 128") and SEC
Staff Accounting Bulletin No. 98 ("SAB No. 98"). Under the provisions of SFAS
No. 128 and SAB No. 98, basic net loss per share is computed by dividing the
net loss available to common stockholders for the period by the weighted
average number of common shares outstanding during the period. Diluted net loss
per share is computed by dividing the net loss for the period by the weighted
average number of common and potential common shares outstanding during the
period, if their effect is dilutive. Potential common shares are comprised of
incremental shares of Common Stock issuable upon the exercise of stock options
and warrants and upon the conversion of Convertible Preferred Stock.

 Pro Forma Net Loss Per Share (Unaudited)

   Pro forma net loss per share for the year ended December 31, 1999 is
computed using the weighted average number of common shares outstanding,
including the conversion of the Company's Series A, Series B and Series C
Convertible Preferred Stock into shares of the Company's Common Stock effective
upon the closing of the Company's initial public offering, as if such
conversion occurred on January 1, 1999, or at the date of original issuance, if
later. The resulting pro forma adjustment includes (i) an increase in the
weighted average shares used to compute the basic net loss per share by
9,748,844 shares and (ii) a decrease in the net loss attributable to common
stockholders for the accretion of mandatorily redeemable convertible preferred
stock of $4,862,000. The calculation of diluted net loss per share excludes
potential shares of common stock as the effect of their inclusion would be
antidilutive. Pro forma potential common stock consists of incremental shares
of common stock issuable upon the exercise of stock options.

 Income Taxes

   Income taxes are accounted for using an asset and liability approach.
Deferred income tax assets and liabilities are determined based on the
differences between the financial reporting and tax bases of assets and
liabilities and are measured using the currently enacted tax rates and laws. In
addition, deferred tax assets are recorded for the future benefit of utilizing
net operating loss and research and development credit carryforwards. A
valuation allowance is provided against deferred tax assets unless it is more
likely than not that they will be realized, either through the generation of
future taxable income or through carryback potential.

 Comprehensive Income

   The Company follows the provisions of Statement of Financial Accounting
Standards No. 130, "Reporting Comprehensive Income" ("SFAS No. 130"). SFAS No.
130 establishes standards for reporting comprehensive income and its components
in financial statements. Comprehensive income, as defined, includes all changes
in equity (net assets) during a period from non-owner sources.

 Segment Information

   The Company follows the provisions of Statement of Financial Accounting
Standards No. 131, "Disclosures about Segments of an Enterprise and Related
Information" ("SFAS No. 131"). The Company identifies its operating segments
based on business activities, management responsibility and geographical
location. During the periods presented the Company operated in a single
business segment.

 New Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards No. 133, "Accounting for
Derivatives and Hedging Activities" ("SFAS No. 133"). This statement
establishes accounting and reporting standards of derivative instruments,
including certain derivative instruments embedded in other contracts, and for
hedging activities. SFAS No. 133 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 and will be effective as
of June 15, 2000. The adoption of SFAS No. 133 is not expected to have a
material effect on the Company's results of operations, financial condition or
cash flows.

</TABLE>

   The Company has incurred losses for the years ended December 31, 1997, 1998
and 1999. Management believes that, based on the history of such losses and
projected near-term future losses, the weight of available evidence indicates
that it is more likely than not that the Company will not be able to realize
its deferred tax assets and thus a full valuation reserve has been recorded at
December 31, 1997, 1998 and 1999.

   As of December 31, 1999, the Company had approximately $13.0 million of
federal net operating loss carryforwards and approximately $11.0 million of
state net operating loss carryforwards available to offset future taxable
income. The federal net operating loss carryforwards will expire between 2011
and 2019 and the state net operating loss carryforwards will expire between
2004 and 2006, if not utilized.

   Under the Tax Reform Act of 1986, the amounts of and the benefit from net
operating losses that can be carried forward may be limited in certain
circumstances including, but not limited to, a cumulative stock ownership
change of more than 50% over a three-year period, as defined. Any unused annual
limitation may be carried forward to future years for the balance of the net
operating loss carryforward period.

NOTE 5--BORROWINGS:

 Line of Credit

   During November 1999, the Company terminated a line of credit with Silicon
Valley Bank. The line of credit provided for borrowings of up to $1,000,000
which were secured by the Company's assets. The line of credit charged interest
at a rate of 9.00% per annum. Under the line of credit, the Company was
required to maintain certain financial ratios as stipulated in the agreement.

 Equipment Lease Line

   During November 1999, the Company paid in full the balance outstanding under
an equipment lease financing line with Silicon Valley Bank. The equipment lease
line provides for borrowings of up to $600,000 which are secured by the
Company's assets. The Company's ability to draw on the financing line expires
on June 22, 2000. The lease line bears interest at a rate of 9.75% per annum.
Under the line of credit, the Company is required to maintain certain financial
covenants.

 Loan Agreement

   On November 17, 1999, the Company entered into a loan agreement with a
financial institution. This agreement provides for borrowings of up to
$4,000,000 under a term loan and $2,000,000 under a revolving line of credit.
Borrowing under the term loan bears interest at prime rate plus 2.00% (10.75%
currently) with accrued interest paid monthly and is due at November 30, 2000.
Borrowing under the line of credit is limited to the lesser of 80% of the
amount of the eligible accounts receivable or $2,000,000, and bears interest at
prime rate plus 2.00% (10.75% currently). The Company borrowed the entire
$4,000,000 available under the term loan on the date of the agreement. Assets
of the Company, including cash and cash equivalents, accounts receivable and
property and equipment, are pledged as collateral for borrowings under this
agreement.

   In connection with such debt financing, the Company issued warrants to
purchase 160,000 shares of Series C Mandatorily Redeemable Preferred Stock at
$2.50 per share, which expire in November 2004. The value of the warrants was
determined using the Black-Scholes valuation model. The expense amounting to
$118,000 will be recognized as additional interest expense over the term of the
borrowing arrangement. The warrants became exercisable upon the closing of the
loan agreement.

NOTE 6--COMMITMENTS AND CONTINGENCIES:

   From time to time, the Company may have certain contingent liabilities that
arise in the ordinary course of its business activities. The company accrues
contingent liabilities when it is probable that future expenditures will be
made and such expenditures can be reasonably estimated. In the opinion of
management, there are no pending claims of which the outcome is expected to
result in a material adverse effect in the financial position or results of
operations of the company.

 Lease Commitments

   The Company leases office space, equipment and an automobile under
noncancelable operating and capital leases. Rent expense under the operating
leases was approximately $157,000, $214,000 and $828,000 for the years ended
December 31, 1997, 1998 and 1999, respectively.

   Future minimum lease payments under the capital and noncancelable operating
leases at December 31, 1999, are as follows:

   The holders of Convertible Preferred Stock have the following rights and
preferences:

 Voting

   Each share of Series A, Series B and Series C has voting rights equal to an
equivalent number of shares of Common Stock into which it is convertible and
votes together as one class with the Common Stock.

 Dividends

   Holders of Series A, Series B and Series C are entitled to receive
noncumulative dividends as declared by the Board of Directors at a rate of
$0.03, $0.075 and $0.10 per share, respectively, per annum prior to any
dividends being paid to holders of Common Stock. After payment of such
dividends, declared dividends shall be paid to the holders of Common Stock and
Convertible Preferred Stock in such amounts as they would be entitled to
receive if their shares had been converted into shares of Common Stock. No
dividends were declared by the Board from inception through December 31, 1999.

 Liquidation

   In the event of any liquidation, dissolution or winding up of the Company,
including merger or sale of substantially all assets, the Series A, Series B
and Series C shareholders are entitled to receive with each series of
Convertible Preferred Stock, on a pro rata basis, a distribution of $0.50,
$1.25 and $1.25 per share, respectively, plus any unpaid but declared dividends
prior to and in preference to any distribution to the holders of Common Stock.
After the payment has been made to the holders of Series A, Series B and Series
C, the holders of Common Stock are entitled to receive $0.40 per share. The
remaining assets, if any, shall be distributed ratably among the holders of the
Common Stock, Series A, Series B and Series C shareholders.

 Redemption

   The holders of Series C have the right to require the Company to redeem the
then outstanding shares beginning on or after March 31, 2004 in three equal
annual installments which is the fair value of the Series C at the time of
redemption plus unpaid dividends. The holders of Series B have the right to
require the Company to redeem the then outstanding shares any time after March
2004 in three annual installments for a redemption price, which is the fair
value of the Series B at the time of redemption plus unpaid dividends. Fair
values shall

be determined by the Board of Directors but if it is unacceptable to the
holders of the Series C or Series B, then it shall be determined by an
independent investment banking firm. The Series A has no redemption privileges.

   As the future redemption prices of the Series B and Series C shares are
variable in amount, the difference between the Series B and Series C carrying
values and their estimated future redemption value are being accreted ratably
as a charge to additional paid-in capital. The estimated future redemption
value of $11.00 as of December 31, 1999 is based on the mid-point of the range
of share prices anticipated for the proposed initial public offering of the
Company's stock.

   During the years ended December 31, 1997 and 1998, the carrying value of
both the Series B and Series C approximated their estimated future redemption
price and as such no accretion charges were recorded. During the year ended
December 31, 1999, the Company recorded accretion charges of $4.1 million.

 Conversion

   Each share of Series A, Series B and Series C is convertible at the option
of the holder into one share of Common Stock. The conversion ratio of Series B
into Common Stock is subject to certain adjustments to prevent dilution. Series
A, Series B and Series C automatically convert into Common Stock upon the
completion of an underwritten public offering with gross proceeds of at least
$5,000,000, $10,000,000 and $10,000,000 and a public offering price of not less
than $1.75, $4.00 and $4.00 per share, respectively.

 Warrants

   In connection with the issuance of Series A, each holder was granted a
warrant to purchase one share of preferred stock for every four shares of
Series A owned at an exercise price per share of $0.50. The warrants expire at
the earlier of December 31, 1999, the date of the Company's initial public
offering of securities, or the date of acquisition of the Company. The value of
the warrants at the time of their issuance was not material to the consolidated
financial statements.

   During December 1999, warrants for an aggregate of 200,000 shares of Series
A Convertible Preferred Stock were exercised. Gross proceeds from the exercise
were $100,000.

NOTE 9--STOCK OPTION PLAN:

   In 1993, the Board of Directors and shareholders adopted the 1993 Stock
Option Plan (the "1993 Plan") which provides for granting of incentive stock

Plan, the stated exercise price shall not be less than 100% and 85% of the
estimated fair market value of the Common Stock as determined by the Board of
Directors on the date of grant for ISO's and NSO's, respectively. Stock options
granted to a person owning more than 10% of the combined voting power of all
classes of stock of the Company must be issued at 110% of the fair market value
of the stock on the date of grant. The 1993 Plan provides that the options
shall be exercisable over a period not to exceed ten years and shall generally
vest 25% one year after the date of grant and thereafter vest in equal monthly
installments over the remaining 36 months.

   The Company calculated the fair value of each option on the date of grant
using the Black-Scholes pricing model with the following assumptions used for
grants during the applicable period: annual dividend yield of 0%, risk-free
annual interest rates of 4.47% to 6.31% for options granted during the period
from January 1, 1997 through December 31, 1999 and a weighted average expected
option term of five years.

NOTE 10--EMPLOYEE BENEFIT PLAN

   Effective January 1, 1996, and as amended on January 1, 1998, the Company
adopted the Inventa Corporation Retirement Savings Plan (the "Plan") which
qualifies as a thrift plan under Section 401(k) of the Internal Revenue Code.
All full-time employees who are at least 21 years old are eligible to

NOTE 11--MALAYSIAN OPERATIONS:

   In November 1998, the Company announced a formal plan to close its
operations in Malaysia and focus its effort in the United States. Accordingly,
in February 1999, the Company engaged the services of a third party to assist
in the orderly liquidation of the Malaysian subsidiary. In conjunction with
this announcement, the Company made a provision of $250,000 in the consolidated
financial statements for costs to be incurred in connection with the
liquidation of the Malaysian subsidiary. This amount consisted of $157,000 for
the write-down from the liquidation of the assets, $47,000 for remaining trade
obligations, and $46,000 for legal and other professional services to be
provided during the liquidation process. Operations ceased during 1998 and all
employee severance related costs were incurred prior to December 31, 1998.
During 1999, the liquidation of the assets and settlement of the obligations
was completed. As of December 31, 1999, $41,000 remains accrued to cover a
pending claim from a former customer of the Malaysian subsidiary. The Company
anticipates that this claim will be settled during 2000.

NOTE 12--SEGMENT AND GEOGRAPHIC INFORMATION:

   The Company operates in a single industry segment (as defined by SFAS No.

NOTE 13--SUBSEQUENT EVENTS:

 Series D Mandatorily Redeemable Preferred Stock

   On January 19, 2000, 3,000,000 shares of Series D Mandatorily Redeemable
Preferred Stock were issued at a price of $7.41 per share for gross proceeds of
approximately $22.2 million. The difference between the deemed fair value of
the series D preferred stock of $11.00 and the price per share of $7.41 was
considered to be a beneficial conversion feature analogous to a dividend to the
preferred stockholders as prescribed under the provisions of EITF 98-5,
Accounting for Convertible Securities with Beneficial Conversion Features or
Contingently Adjustable Conversion Ratios. Due to the conversion rights, the
deemed fair value of the Series D preferred stock was based on the mid-point of
the range of share prices anticipated for the proposed initial public offering
of the Company's common stock. The value of the beneficial conversion feature
of $10.8 million was recognized immediately as a charge to net loss
attributable to common stockholders at the date of issuance as the preferred
stockholders have the right to immediately convert their preferred shares at
their option.

 Acquisition

   Effective January 26, 2000, the Company acquired all the outstanding shares
of common stock of XTEND-Tech, Inc., a provider of information technology
consulting services. Total consideration paid in connection with this
acquisition was 1,350,000 shares of the Company's common stock with a value of
$14,850,000. The deemed fair value of the Company's common stock on the date
the merger agreement was

signed was $11.00 per share. The deemed fair value of the common stock was
based on the mid-point of the range of share prices anticipated for the
proposed initial public offering. The consideration consisted of a combination
of the purchase price paid for the outstanding common stock of XTEND-Tech and
consideration to certain employee stockholders of XTEND-Tech for continued
employment with the Company.

   The acquisition will be accounted for using the purchase method of
accounting. The amount of the consideration treated as purchase price for this
acquisition was approximately $8,779,000. The purchase price was allocated to
the tangible and intangible assets acquired and liabilities assumed based upon
their respective fair values at the acquisition date. The purchase price
consisted of 798,052 shares of the Company's common stock. The estimated
allocation of the purchase price is as follows:

</TABLE>

   The amortization of the intangible assets will occur over the estimated
periods to be benefited. The estimated weighted average period to be benefitted
from the intangible assets for the workforce, covenants not to compete and the
residual goodwill, created as a result of the acquisition of XTEND-Tech, Inc.
is approximately three years.

   Additionally, the Company signed restricted stock agreements with certain
employee stockholders of XTEND-Tech, Inc. as consideration for continued
employment. Under these agreements, the stockholders receive 849,150 shares of
the Company's common stock with a fair value of approximately $9,341,000 at the
effective date of the stock purchase agreement. Under the restricted stock
agreement, 297,202 shares vest immediately and therefore constitute part of the
purchase price of the tangible and intangible assets of XTEND-Tech, Inc. The
remaining 551,948 shares are subject to the Company's right to repurchase upon
termination of employment for $0.01 per share. Twenty three percent of these
restricted shares vest and are released from the Company's repurchase right on
the first anniversary of the effective date of the agreement. The remaining
shares vest and are released from the Company's repurchase right evenly over
the two years following the first anniversary. The fair value of the unvested
shares, amounting to $6,071,000 has been recorded as deferred stock-based
compensation which will be amortized over the three year vesting period of the
restricted stock as described above in accordance with FASB Interpretation No.
28.

 Letter of Credit

   In February 2000, the Company entered into two letters of credit for
approximately $2.8 million and $198,000 to secure lease deposits to expand into
two new office facilities. The letters of credit expire February 2001 and are
collateralized by certificates of deposit in the same amounts.

 Reincorporation (unaudited)

   On March 23, 2000, the Company reincorporated in Delaware as Inventa
Technologies, Inc.

               NOTES TO PRO FORMA COMBINED FINANCIAL INFORMATION
                                  (UNAUDITED)
                                  (Continued)

(1) Reflects the preliminary allocation of the purchase price to the intangible
    assets and goodwill acquired in the XTEND-Tech acquisition. The preliminary
    allocation has resulted in intangible assets, including assembled workforce
    estimated at approximately $5,100,000, covenants not to compete, estimated
    at approximately $1,000,000 and estimated goodwill of approximately
    $2,631,000, which are being amortized over their weighted average life of
    three years.

   The total estimated purchase price for the XTEND-Tech acquisition has been
   allocated on a preliminary basis to assets and liabilities based on
   management's best estimates of their fair value with the excess costs over
   the net assets acquired allocated to intangible assets and goodwill. This
   allocation is subject to change pending a final analysis of the value of the
   assets acquired and, liabilities assumed, upon closure of the acquisition.
   The impact of such changes could be material.

(2) Reflects the issuance of 1,350,000 shares of Inventa Common Stock with a
    fair value of $14,850,000 in connection with the XTEND-Tech acquisition.

(3) Reflects the unearned compensation recorded for restricted stock issued in
    connection with the purchase of XTEND-Tech. Of the 1,350,000 shares issued,
    798,052 shares with a fair value of $8,779,000 were immediately vested and
    as such represent the purchase price. The remaining 551,948 shares which
    were issued to XTEND-Tech employee stockholders are subject to the
    Company's right to repurchase the shares upon the termination of employment
    with Inventa. The fair value of these restricted shares in the amount of
    $6,071,000 has been recorded as unearned deferred compensation and will be
    amortized over the vesting period of the restricted shares.

(4) Reflects the amortization of the unearned deferred stock-based compensation
    referred to in Note 3 above.

(5) Reflects the amortization of the intangible assets and goodwill referred to
    in Note 1 above.

(6) Represents elimination of intercompany transactions with XTEND-Tech.

(7) Pro forma net loss reflects the impact of the adjustments above. Basic and
    diluted net loss per share (pro forma) is computed using the weighted-
    average number of shares of common stock outstanding after the issuance of
    Inventa common stock in connection with the XTEND-Tech acquisition,
    assuming such stock was issued on January 1, 1999 and excluding the 551,948
    shares subject to repurchase.

(8) Reflects elimination of XTEND-Tech stockholders' equity.

                         NOTES TO FINANCIAL STATEMENTS

NOTE 1--THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

 The Company

   XTEND-Tech, Inc. (the "Company") was incorporated in the state of New Jersey
on January 29, 1999. The Company is an information technology consulting
organization providing clients with technology expertise in all phases of
systems engineering and most software development methodologies for the major
industries in the United States.

   The Company operations have initially been focused on the New Jersey, New
York, Pennsylvania and Delaware areas, with two offices in New Jersey.

 Use of Estimates

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

 Financial Instruments

   The Company's financial instruments including cash and cash equivalents,
accounts receivable, and accounts payable are carried at cost, which
approximates their fair value because of the short-term maturity of these
instruments. The carrying value of the Company's capital leases and the long
term borrowings approximate fair value because the implicit rates approximate
prevailing market rates.

 Accounts Receivable

   Bad debts are provided on the allowance method based on management's
evaluation of outstanding accounts receivable. No provision for bad debts was
considered necessary by management at December 31, 1999.

 Property and Equipment

   Property and equipment, primarily computer hardware, are stated at cost less
accumulated depreciation. Depreciation is calculated using the straight-line
method over the useful lives of the assets. Computer hardware is depreciated
over four years. Maintenance and repairs are charged to expense when incurred,
and the cost of additions and improvements is capitalized.

 Revenue Recognition

   Revenues are derived from sales of the Company's consulting services to end-
users. Revenue is recognized on a time and material basis when services are
provided.

 Income Taxes

   The accrual basis of accounting is used for income tax reporting purposes. A
provision of $19,900 was recorded for federal and state income taxes as of
December 31, 1999. The Company, with the consent of its shareholders, has
elected to be taxed as a "C" Corporation for federal and state income tax
purposes.

   The Company utilizes the asset and liability method of accounting for income
taxes under which deferred tax assets and liabilities are recognized for the
tax consequences of temporary differences by applying enacted

                                      F-29
<PAGE>

                                XTEND-TECH, INC.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

statutory tax rates applicable to future years to differences between the
financial statement carrying amounts and the tax bases of existing assets and
liabilities. The effect on deferred tax assets and liabilities of a change in
tax rates is recognized in income in the period when the change in tax rates is
enacted.

 Concentration of Credit Risks

   Financial instruments that potentially subject the Company to concentrations
of credit risk consist principally of trade accounts receivable. Concentrations
of credit risk with respect to trade receivables are limited based on
management's evaluation of the relationship with the Company's clients. The
Company's four largest customers accounted for approximately 77% of revenues
for the period from inception (January 29, 1999) to December 31, 1999. IDCS,
Inc. (Note 2) accounted for 40% of revenues during the same period. At December
31, 1999, these four customers accounted for approximately 43% of accounts
receivable. These balances were subsequently collected.

NOTE 2--RELATED PARTY TRANSACTIONS:

   Since its incorporation in January 1999, the Company's activities have been
financed on a needs basis through a prepayment note, payable to Intermodal
Database Communication Systems, Inc. ("IDCS"), a related party that owns 14.25%
of the Company. Through this prepayment note, the Company agrees to pay IDCS
the remaining prepayment principal sum that may be due to IDCS at any time upon
IDCS's request. In the event the Company refuses to repay any amount due within
3 days notice of demand, these amounts would accrue interest at a prime rate
plus 5.00%. The total advances from IDCS during the period ended December 31,
1999 amounted to $1,105,000. As of December 31, 1999, the outstanding balance
on these advances amounted to $326,435.

   The Company has also entered into a capital lease agreement (Note 7) with
Selecto Flash, Inc., a related party which is represented on the Company's
Board of Directors.

NOTE 3--PROPERTY AND EQUIPMENT:

  Property and equipment consist of the following as of December 31, 1999:

</TABLE>

NOTE 4--EMPLOYEE BENEFIT PLAN:

   The Company participates in a self directed 401(k) Plan (the Plan), covering
all employees, which qualifies under Section 401(k) of the Internal Revenue
Code. The Plan allows eligible employees to make tax deferred contributions of
up to 15% of their compensation, subject to the legal maximum amount. The
Company does not match employees' contributions. Loans to participants are
permitted in an amount not to exceed the lesser of one-half of the
participant's non-forfeitable interest under the Plan or $50,000.

   The Company also provides its employees with health, long-term disability

Item 14. Indemnification of Officers and Directors.

   Section 145 of the Delaware General Corporation Law permits indemnification
of officers, directors and other corporate agents under certain circumstances
and subject to certain limitations. The Registrant's certificate of
incorporation and bylaws provide that the Registrant shall indemnify its
directors, officers, employees and agents to the full extent permitted by
Delaware General Corporation Law, including in circumstances in which
indemnification is otherwise discretionary under Delaware law. In addition, the
Registrant intends to enter into separate indemnification agreements with its
directors, officers and certain employees that would require the Registrant,
among other things, to indemnify them against certain liabilities that may
arise by reason of their status or service (other than liabilities arising from
willful misconduct of a culpable nature). The Registrant also intends to
maintain director and officer liability insurance, if available on reasonable
terms.

   These indemnification provisions and the indemnification agreements to be
entered into between the Registrant and its officers and directors may be
sufficiently broad to permit indemnification of the Registrant's officers and
directors for liabilities (including reimbursement of expenses incurred)
arising under the Securities Act.

   The Registrant intends to obtain in conjunction with the effectiveness of
the Registration Statement a policy of directors' and officers' liability
insurance that insures the Registrant's directors and officers against the cost
of defense, settlement or payment of a judgment under certain circumstances.

   The underwriting agreement filed as Exhibit 1.1 to this Registration
Statement provides for indemnification by the underwriters of the Registrant
and its officers and directors for certain liabilities arising under the
Securities Act, or otherwise.

Item 15. Recent Sales of Unregistered Securities.

   Except as otherwise noted, we have issued and sold the following securities
within the last three years and through February 29, 2000:

   On February 14, 1997, we sold an aggregate of 2,560,000 shares of our series
B preferred stock at a price of $1.25 per share to five investors and their
affiliates.

   On May 11, 1998, and May 28, 1999, we sold an aggregate of 8,055,511 shares
of our series C preferred stock at a price of $1.25 per share to seven
investors and their affiliates.

   On January 19, 2000, we sold an aggregate of 3,000,000 shares of our series
D preferred stock at a price of $7.41 per share to seven investors and their
affiliates.

   On January 26, 2000, we issued 1,350,000 shares of common stock to 11
individuals and one institutional investor in connection with our acquisition
of XTEND-Tech. These issuances were deemed to be exempt from registration under
the Securities Act in reliance upon Section 4(2) of the Securities Act, as
transactions by an issuer not involving any public offering.

   We issued 200,000 shares of our series A preferred stock, at an exercise
price per share of $0.50, pursuant to the exercise of warrants issued in
connection with our original issuance of our series A preferred stock.

   We issued a warrant to acquire 160,000 of series C preferred stock, at an
exercise price of $2.50 per share, in connection with our borrowing of
$4,000,000 under a term loan.

   We issued 2,271,000 shares of common stock and 400,000 shares of our series
A preferred stock pursuant to a two-for-one stock split declared on January 29,
1997.

   Since our inception, we have granted options to purchase 5,586,220 shares of
our common stock to employees, directors and consultants under our 1993 Plan at
exercise prices ranging from $0.05 to $6.50 per share. Of the 5,586,220 options
granted, 3,993,653 remain outstanding, 648,163 shares of common stock have been
purchased pursuant to exercises of stock options and options to acquire
944,404 shares have been cancelled and are available for grant under our 1993
Plan.

   The sales and issuances of securities in the transactions described above
were deemed to be exempt from registration under the Securities Act in reliance
upon Section 4(2) of the Securities Act, Regulation D promulgated thereunder or
Rule 701 promulgated under Section 3(b) of the Securities Act, as transactions
by an issuer not involving any public offering or transactions pursuant to
compensatory benefit plans and contracts relating to compensation as provided
under Rule 701. The recipients of securities in each transaction represented
their intentions to acquire the securities for investment purposes only and not
with a view to or for sale in connection with any distribution thereof and
appropriate legends were affixed to the securities issued in such transactions.
All recipients either received adequate information about us or had access,
through their employment or other relationships with us, to adequate
information about us.

   There were no underwriters employed in connection with any of the
transactions set forth in Item 15.

Item 17. Undertakings.

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

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

   The undersigned registrant hereby undertakes that:

survive the Closing hereunder (even if Inventa knew or had reason to know of any
misrepresentation or breach of warranty at the time of Closing) and continue in
full force and effect for a period of twenty-four (24) months thereafter, except
that those set forth in Section 3(k) ("Tax Matters") shall survive until the
expiration of the applicable Statute of Limitations.

     8.   General Indemnification.
          -----------------------

          (a)  Subject to Section 8(c) hereunder, the Shareholders hereby
jointly and severally indemnify and agree to hold harmless Inventa (at and after
the Closing Date) in respect of any claims, costs, demands, liabilities, losses
and expenses (including, without limitation, reasonable legal and other out-of-
pocket fees and expenses for investigating, defending or settling any actions or
threatened actions) (all of which are referred to herein individually as a
"Deficiency" and collectively as "Deficiencies") incurred or suffered by Inventa
in connection with any misrepresentation or breach of any representation,
warranty, covenant or agreement made by XTEND or any Shareholder in this
Agreement (including but not limited to representations made by the other
Shareholders pursuant to Section 2(a), or in any certificate, instrument,
schedule or document given by XTEND or any Shareholder pursuant to this
Agreement or the Escrow Agreement.

          (b)  Notwithstanding the foregoing, neither the Shareholders nor
Inventa shall have any obligation to indemnify and/or hold the other harmless in
respect of any claims, costs, demands, liabilities, losses, and expenses of any
kind (including, without limitation, reasonable legal and other out-of-pocket
fees and expenses for investigating, defending, or settling any actions or
threatened actions) made by Sybase, Inc. relating to violations by any
Shareholder or any employee of XTEND or Inventa of any non-competition, and/or
non-solicitation and/or any other hiring agreements entered into by such
Shareholder or employee with Sybase, Inc.

          (c)  Shareholders shall not be liable to Inventa under this Article 8
or otherwise under this Agreement for any claims, costs, demands, liabilities,
losses and expenses of any kind (including without limitation, reasonable legal
and other out-of-pocket fees and expenses for investigating, defending, or
settling any actions or threatened actions arising out of claims made by third
party(s) relating to Shareholders violation of any term(s) of this Agreement,
until the amount otherwise due Inventa for indemnification as provided herein
exceeds Seventy-Five Thousand Dollars ($75,000) in the aggregate, in which case,
Shareholders shall be liable to Inventa for all such amounts, including without
limitation, the first Seventy-Five Thousand Dollars ($75,000) thereof;

                                      -18-
<PAGE>

provided, however, that Shareholders indemnification obligations under Section
8(a), and otherwise, shall in no event exceed an aggregate of $2,500,000.

          (d)  Losses Net of Insurance and Tax Benefits.  In calculating any
               ----------------------------------------
Deficiency suffered by the Company, Inventa or any affiliate of any of them,
arising out of this Agreement, there shall be deducted any insurance recovery in
respect of such Deficiency. Further, any indemnity payment hereunder with
respect to any Deficiency shall be calculated on an "after-tax basis", meaning
that amount which is sufficient to compensate the indemnified party for the
event giving rise to such Deficiency determined after taking into account all
reduction in federal, state, local and foreign taxes (including estimated taxes)
payable by the indemnified party as a result of the event giving rise to such
Deficiency.

     9.   Establishment of Escrow.  In order to provide protection for Inventa
          -----------------------
from and after the Closing, an escrow account ("Escrow") shall be established on
behalf of Inventa, which Escrow shall, (i) be subject to the provisions of the
Escrow Agreement, attached hereto as Exhibit C, and (ii) provide the first funds
from which claims under the indemnification provisions set forth herein shall be
paid. The Escrow shall be funded, as of Closing, with 551,948 shares of Inventa
Common Stock otherwise issuable hereunder (the "Escrow Shares") to those
Shareholders who enter into the Shareholders Restricted Stock Agreements
referenced in Section 6(a)(iii) hereunder (the "Stock Agreements") to be
available for repurchase pursuant to the Inventa Repurchase Option provision
delineated in the Shareholders Restricted Stock Agreements, of which Escrow
Shares 337,500 shall also be held to provide a fund (to the extent that the
value of said 337,500 Escrow Shares satisfies the $2,500,000 Shareholders
Indemnification obligation set forth in Section 8(c)) for the Shareholders
indemnification of Inventa, hereunder. For purposes of this Section 9, the per
share value of said 337,500 Escrow Shares shall be, (i) if Inventa is then a
public company, the average of the Closing prices of Inventa common stock for
the thirty (30) trading days immediately preceding the Shareholders deemed
receipt of notice of a claim, delivered pursuant to Section 11 (g) or (ii) if
Inventa is then not a public Company, $7.41. If Inventa is a public company but
its shares are not then being traded, such per share value shall be determined
by an appraiser mutually acceptable to the Parties.

               -------------

deemed to extend to any prior or subsequent default, misrepresentation, or
breach of warranty or covenant hereunder or affect in any way any rights arising

          (j)  Severability.  Any term or provision of this Agreement that is
               ------------
invalid or unenforceable in any situation in any jurisdiction shall not affect

          (l)  Construction.  The Parties have participated jointly in the
               ------------

foreign statute or law shall be deemed also to refer to all rules and
regulations promulgated thereunder, unless the context requires otherwise. The
word "including" shall mean including without limitation. The Parties intend
that each representation, warranty, and covenant contained herein shall have
independent significance. If any Party has breached any representation,
warranty, or covenant contained herein in any respect, the fact that there
exists another representation, warranty, or covenant relating to the same
subject matter (regardless of the relative levels of specificity) that the Party
has not breached shall not detract from or mitigate the fact that the Party is
in breach of the first representation, warranty, or covenant.

          (m)  Incorporation of Exhibits and Schedules.  The Exhibits and
               ---------------------------------------
Schedules identified in this Agreement are incorporated herein by reference and

               --------------------

agrees that the other Parties may be entitled to an injunction or injunctions to
prevent breaches of the provisions of this Agreement and to enforce specifically
this Agreement and the terms and provisions hereof in any action instituted in
any court of the United States or any state thereof having jurisdiction over the
Parties and the matter in addition to any other remedy to which they may be
entitled, at law or in equity.

          (o)  Submission to Jurisdiction.  Each of the Parties submits to the
               --------------------------
jurisdiction of any state or federal court sitting in Santa Clara County,
California, in any action or proceeding arising out of or relating to this
Agreement and agrees that all claims in respect of the action or

                                      -22-
<PAGE>

proceeding may be heard and determined in any such court. Each Party also agrees
not to bring any action or proceeding arising out of or relating to this
Agreement in any other court. Each of the Parties waives any defense of
inconvenient forum to the maintenance of any action or proceeding so brought and
waives any bond, surety, or other security that might be required of any other
Party with respect thereto. Each Party agrees that a final judgment in any
action or proceeding so brought shall be conclusive and may be enforced by suit
on the judgment or in any other manner provided by law or at equity.

adjusted for any stock dividends, combinations, splits, recapitalizations and
the like with respect to such shares) or, if greater (as determined on a per
annum basis and on an as converted basis for the Preferred Stock), an amount
equal to that paid on the Common Stock. Such dividends shall be payable when,
as, and if declared by the Board of Directors, and shall not be cumulative, and
no right shall accrue to holders of Common Stock or Preferred Stock by reason of
the fact that dividends on said shares are not declared in any prior period.
After payment has been made to the holders of Preferred Stock of the full
amounts to which they shall be entitled as set forth in this Section 1, the
holders of Preferred Stock and Common Stock shall be entitled to receive ratably
on an as-converted basis any remaining funds declared as dividends.

      2. Liquidation Preference.

            (a) Preferred Preference. In the event of any liquidation,
dissolution, or winding up of the Corporation, either voluntary or involuntary,
the holders of the Series C Preferred and Series D Preferred shall be entitled
to receive on a pro rata basis, prior and in preference to any distribution of
any of the assets or surplus funds of the Corporation to the holders of the
Series A Preferred, Series B Preferred and Common Stock, by reason of their
ownership of such stock, an amount per share equal to the sum of $1.25 per share
of Series C Preferred and $7.41 per share of Series D Preferred (in each case as
adjusted for any stock dividends, combinations, splits, recapitalizations and
the like with respect to such shares) plus declared and unpaid dividends, for
each share of Series C Preferred or Series D Preferred then held by them. If
upon the occurrence of such event, the assets and funds thus distributed among
the holders of the Series C Preferred and Series D Preferred shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then the entire assets and funds of the Corporation
legally available for distribution shall be distributed among the holders of the
Series C Preferred and Series D Preferred in proportion to the aggregate
liquidation preference of the shares held by each such holder.

            (b) After payment has been made to the holders of the Series C
Preferred and Series D Preferred of the full amounts to which they shall be
entitled as set forth in paragraph 2(a) above, the holders of Series A Preferred
and Series B Preferred shall be entitled to receive, prior and in preference to
any distribution of any of the assets of this Corporation to the holders of
Common Stock by reason of their ownership thereof, an amount per share equal to
$0.50 for each outstanding share of Series A Preferred (as adjusted for any
stock dividends, combinations, splits, recapitalizations and the like with
respect to such shares), and $1.25 for each outstanding share of Series B
Preferred (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares), plus an amount
equal to any declared but unpaid dividends for each share of Series A Preferred
and Series B Preferred then held by them. If upon the occurrence of such event,
the assets and funds thus distributed among the holders of Series A Preferred
and Series B Preferred shall be insufficient to permit the payment to such
holders of the full aforesaid preferential amounts, then the entire assets and
funds of this Corporation legally available for distribution shall be
distributed ratably among the holders of the Series A Preferred and Series B
Preferred in proportion to the aggregate Series A Preferred liquidation
preference and the Series B Preferred liquidation preference.

            (c) After payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled to as set forth in
paragraphs 2(a) and 2(b) above, the holders of the Common Stock shall then be
entitled to receive the amount of $0.40 per share for each share of Common Stock
then held by them (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares), plus an amount
equal to all declared but unpaid dividends for each share of Common Stock then
held by them. If the assets and funds thus distributed among the holders of the
Common Stock shall be insufficient to permit the payment to such holders of the
full aforesaid amount, then the entire assets and funds of the Corporation
legally available for distribution, shall be distributed among the holders of
the Common Stock ratably on a per-share basis.

            (d) After payment has been made to the holders of the Preferred
Stock and the Common Stock of the full amount to which they shall be entitled as
set forth in paragraphs 2(a), 2(b) and 2(c) above, the holders of the Preferred
Stock and Common Stock shall be entitled to receive ratably on a per-share basis
all the remaining assets based upon the number of shares of Common Stock into
which each share of Preferred Stock is then convertible; provided, however, that
the holders of Preferred Stock shall not be entitled to receive pursuant to this
paragraph (d) (including amounts received pursuant to paragraphs 2 (a) and 2(b)
above) more than a total of $1.00 per share of Series A Preferred, $2.50 per
share of Series B Preferred, $2.50 per share of Series C Preferred and $14.82
per share of Series D Preferred then held by them (as adjusted for any stock
dividends, combinations, splits, recapitalizations and the like with respect to
such shares) plus declared and unpaid dividends.

            (e) After payment has been made to the holders of the Preferred
Stock and the Common Stock of the full amounts to which they shall be entitled
as set forth in paragraphs 2(a), 2(b), 2(c) and 2(d) above, the holders of the
Common Stock shall be entitled to receive ratably on a per-share basis all the
remaining assets.


                                      -3-

            (f) Mergers. Unless waived by the approval (by vote or written
consent, as provided by law) of the holders of 66 2/3% of the then outstanding
Series C Preferred and holders of 66 2/3% of the then outstanding Series D
Preferred, for purposes of this Section 2, a merger or consolidation of the
Corporation with or into any other corporation or corporations, or the merger of
any other corporation or corporations into the Corporation, in which the
shareholders of the Corporation receive distributions in cash or securities of
another corporation or corporations as a result of such consolidation or merger,
a reorganization, including a sale of the capital stock of the Corporation,
where the shareholders of the Corporation immediately prior to the transaction
possess less than 50% of the voting power of the surviving entity (or its
parent) immediately after the transaction, or a sale of all or substantially all
of the assets of the Corporation, shall be treated as a liquidation, dissolution
or winding up of the Corporation; provided that the holders of the Preferred
Stock and the Common Stock shall each be paid the liquidation preference in cash
or in the securities received or in a combination thereof (which combination
shall be in the same proportions as the consideration received in the
transaction). Any securities to be delivered to the holders of the Preferred
Stock and Common Stock upon merger, reorganization or sale of substantially all
the assets of the Corporation shall be valued as follows:

                  (i) if traded on a securities exchange, the value shall be
deemed to be the average of the closing prices of the securities on such
exchange over the 30-day period ending three (3) business days prior to the
closing;

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

                  (iii) if there is no active public market, the value shall be
the fair market value thereof as mutually determined by the Corporation and the
holders of not less than a majority of the outstanding shares of the Preferred
Stock, provided that if the Corporation and the holders of a majority of the
outstanding shares of the Preferred Stock are unable to reach agreement, then by
independent appraisal by an investment banker hired and paid by the Corporation,
but acceptable to the holders of a majority of the outstanding shares of
Preferred Stock.

      3. Conversion. The holders of Preferred Stock shall have conversion rights
as follows (the "Conversion Rights"):

            (a) Right to Convert. Each share of Preferred Stock shall be
convertible into share(s) of Common Stock without the payment of any additional
consideration by the holder thereof and, at the option of the holder thereof, at
any time after the date of issuance of such share, at the office of the
Corporation or any transfer agent for the Preferred Stock. Each share of
Preferred Stock shall be convertible into such number of fully paid and
nonassessable shares of Common Stock as is determined by dividing the applicable
Original Issue Price of such share of Preferred Stock by the Conversion Price
(the "Conversion Price") at the time in effect for a share of such series of
Preferred Stock. The Original Issue Price per share of Series A Preferred is
$0.50, and the Conversion Price per share of Series A Preferred initially shall
be $0.50. The Original Issue Price per share of


                                      -4-
<PAGE>

Series B Preferred is $1.25, and the Conversion Price per share of Series B
Preferred initially shall be $1.25. The Original Issue Price per share of Series
C Preferred is $1.25, and the Conversion Price per share of Series C Preferred
initially shall be $1.25. The Original Issue Price per share of Series D
Preferred is $7.41, and the Conversion Price per share of Series D Preferred
initially shall be $7.41. The Conversion Price of each series of Preferred Stock
shall be subject to adjustment from time to time as provided below. The number
of shares of Common Stock into which a share of Preferred Stock is convertible
is hereinafter referred to as the "Conversion Rate" of such series.

            (b) Automatic Conversion. Each share of Preferred Stock shall
automatically be converted into shares of Common Stock at the then effective
Conversion Rate immediately upon the closing of a firm commitment underwritten
public offering pursuant to an effective registration statement under the
Securities Act of 1933, as amended, covering the offer and sale of Common Stock
in which the aggregate proceeds raised equals or exceeds $20,000,000 (a
"Qualified Public Offering").

      Notwithstanding the foregoing, each share of Series A Preferred, Series B
Preferred and Series C Preferred shall automatically be converted into shares of
Common Stock at the applicable effective Conversion Rate upon the approval (by
vote or written consent, as provided by law) of (i) the holders of at least 2/3
of the then outstanding shares of Series A Preferred, Series B Preferred and
Series C Preferred (voting together as a separate class) and (ii) the holders of
at least 2/3 of the then outstanding shares of Series C Preferred.

      Notwithstanding the foregoing, each share of Series D Preferred shall
automatically be converted into shares of Common Stock at the applicable
effective Conversion Rate upon the approval (by vote or written consent, as
provided by law) of the holders of at least 2/3 of the then outstanding shares
of Series D Preferred.

            (c) Mechanics of Conversion. Before any holder of the Preferred
Stock shall be entitled to convert the same into shares of Common Stock, he
shall surrender the certificate or certificates therefor, duly endorsed, at the
office of the Corporation or of any transfer agent for the Preferred Stock and
shall give written notice to the Corporation at such office that he elects to
convert the same (except that no such written notice of election to convert
shall be necessary in the event of an automatic conversion pursuant to Section
3(b) hereof). The Corporation shall, as soon as practicable thereafter, issue
and deliver at such office to such holder of Preferred Stock a certificate or
certificates for the number of shares of Common Stock to which such holder shall
be entitled. Such conversion shall be deemed to have been made immediately prior
to the close of business on the date of such surrender of the shares of
Preferred Stock to be converted (except that in the case of an automatic
conversion pursuant to Section 3(b) hereof such conversion shall be deemed to
have been made immediately prior to the closing of the offering referred to in
Section 3(b)) and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock on such date.


                                      -5-
<PAGE>

            (d) Fractional Shares. In lieu of any fractional shares to which the
holder of Preferred Stock would otherwise be entitled, the Corporation shall pay
cash equal to such fraction multiplied by the fair market value of one share of
each such series of Preferred Stock as determined by the Board of Directors of
the Corporation. Whether or not fractional shares are issuable upon such
conversion shall be determined on the basis of the total number of shares of
Preferred Stock of each holder to be converted at such time into Common Stock
and the number of shares of Common Stock issuable upon such aggregate
conversion.

            (e) Adjustment of Conversion Price. The Conversion Price of each
series of Preferred Stock shall be subject to adjustment from time to time as
follows:

                  (i) If the Corporation shall issue any Common Stock other than
"Excluded Stock", as defined below, without consideration or for consideration
per share less than the applicable Conversion Price for such series in effect on
the date of and immediately prior to such issuance, then and in such event, the
Conversion Price in effect for such series shall be reduced, concurrently with
such issuance, to a price determined by multiplying such Conversion Price by a
fraction, the numerator of which shall be the total number of shares of Common
Stock outstanding (including any shares of Common Stock issuable upon conversion
of the Preferred Stock, or deemed to have been issued pursuant to subdivision
(3) of this clause (i) and to clause (ii) below) immediately prior to such
issuance plus the number of shares of Common Stock which the aggregate
consideration received by the Corporation for the total number of shares of
Common Stock so issued would purchase at such Conversion Price; and the
denominator of which shall be the total number of shares of Common Stock
outstanding (including any shares of Common Stock issuable upon conversion of
the Preferred Stock or deemed to have been issued pursuant to subdivision (3) of
this clause (i) and to clause (ii) below) immediately prior to such issuance
plus the additional shares of Common Stock issued in such issuance (but not
including any additional shares of Common Stock deemed to be issued as a result
of any adjustment in the Conversion Price resulting from such issuance).

            For purposes of any adjustment of the Conversion Price pursuant to
this clause (i), the following provisions shall be applicable:

                        (1) In the case of the issuance of Common Stock for
cash, the consideration shall be deemed to be the amount of cash paid therefor
after deducting any discounts or commissions paid or incurred by the Corporation
in connection with the issuance and sale thereof.

                        (2) In the case of the issuance of Common Stock for a
consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair market value thereof as determined by the
Board of Directors of the Corporation, in accordance with generally accepted
accounting treatment; provided, however, that if, at the time of such
determination, the Corporation's Common Stock is traded in the over-the-counter
market or on a national or regional securities exchange, such fair market value
as determined by the board of directors of the Corporation shall not exceed the
aggregate "Current Market Price" (as defined below) of the shares of Common
Stock being issued.

<PAGE>

                        (3) In the case of the issuance of (i) options to
purchase or rights to subscribe for Common Stock (other than Excluded Stock),
(ii) securities by their terms convertible into or exchangeable for Common Stock
(other than Excluded Stock), or (iii) options to purchase or rights to subscribe
for such convertible or exchangeable securities:

                              (A) the aggregate maximum number of shares of
Common Stock deliverable upon exercise of such options to purchase or rights to
subscribe for Common Stock shall be deemed to have been issued at the time such
options or rights were issued and for a consideration equal to the consideration
(determined in the manner provided in subdivisions (1) and (2) above), if any,
received by the Corporation upon the issuance of such options or rights plus the
minimum purchase price provided in such options or rights for the Common Stock
covered thereby;

                              (B) the aggregate maximum number of shares of
Common Stock deliverable upon conversion of or in exchange for any such
convertible or exchangeable securities or upon the exercise of options to
purchase or rights to subscribe for such convertible or exchangeable securities
and subsequent conversion or exchange thereof, shall be deemed to have been
issued at the time such securities were issued or such options or rights were
issued and for a consideration equal to the consideration received by the
Corporation for any such securities and related options or rights (excluding any
cash received on account of accrued interest or accrued dividends), plus the
minimum additional consideration, if any, to be received by the Corporation upon
the conversion or exchange of such securities or the exercise of any related
options or rights (the consideration in each case to be determined in the manner
provided in subdivisions (1) and (2) above);

                              (C) on any change in the number of shares of
Common Stock deliverable upon exercise of any such options or rights or
conversion of or exchange for such convertible or exchangeable securities, or on
any change in the minimum purchase price of such options, rights or securities,
other than a change resulting from the antidilution provisions of such options,
rights or securities, the Conversion Price shall forthwith be readjusted to such
Conversion Price as would have been obtained had the adjustment made upon (x)
the issuance of such options, rights or securities not exercised, converted or
exchanged prior to such change, as the case may be, been made upon the basis of
such change or (y) the options or rights related to such securities not
converted or exchanged prior to such change, as the case may be, been made upon
the basis of such change; and

                              (D) on the expiration of any such options or
rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price shall forthwith be readjusted to such
Conversion Price as would have been obtained had the adjustment made upon the
issuance of such options, rights, convertible or exchangeable securities or
options or rights related to such convertible or exchangeable securities, as the
case may be, been made upon the basis of the issuance of only the number of
shares of Common Stock actually issued upon the exercise of such options or
rights, upon the conversion or exchange of such convertible or exchangeable
securities or


                                      -7-
<PAGE>

upon the exercise of the options or rights related to such
convertible or exchangeable securities, as the case may be.

                        (ii) "Excluded Stock" shall mean:

                              (1) all shares of Common Stock issued and
outstanding on the date this document is filed with the California Secretary of
State and all shares issuable upon exercise of options or warrants outstanding
on the date this document is filed with the California Secretary of State;

                              (2) all shares of Series A Preferred, Series B
Preferred, Series C Preferred and Series D Preferred and the Common Stock into
which such shares are convertible;

                              (3) up to 1,562,808 shares of Common Stock,
warrants or options to purchase Common Stock or other securities issued to
officers, directors, consultants or employees of the Corporation pursuant to any
plan or arrangement approved by the Board of Directors of the Corporation; and

                              (4) shares of Common Stock, warrants or options to
purchase Common Stock or other securities issued to officers, directors,
consultants or employees of the Corporation pursuant to any plan or arrangement
approved by a 2/3 vote of the Board of Directors of the Corporation.

      All outstanding shares of Excluded Stock (including any shares issuable
upon conversion of the Preferred Stock) shall be deemed to be outstanding for
all purposes of the computations of Section 3(e)(i) above.

                        (iii) If the number of shares of Common Stock
outstanding at any time after the date hereof is increased by a stock dividend
payable in shares of Common Stock or by a subdivision or split-up of shares of
Common Stock, then, on the date such payment is made or such change is
effective, the respective Conversion Prices of Series A Preferred, Series B
Preferred, Series C Preferred and Series D Preferred shall be appropriately
decreased so that the number of shares of Common Stock issuable on conversion of
any shares of such series of Preferred Stock shall be increased in proportion to
such increase of outstanding shares of Common Stock.

                        (iv) If the number of shares of Common Stock outstanding
at any time after the date hereof is decreased by a combination of the
outstanding shares of Common Stock, then, on the effective date of such
combination, the respective Conversion Prices of Series A Preferred, Series B
Preferred, Series C Preferred and Series D Preferred shall be appropriately
increased so that the number of shares of Common Stock issuable on conversion of
any shares of a series of Preferred Stock shall be decreased in proportion to
such decrease in outstanding shares of Common Stock.

                        (v) In case the Corporation shall declare a cash
dividend upon its Common Stock payable otherwise than out of retained earnings
or shall distribute to holders of its Common


                                      -8-
<PAGE>

Stock shares of its capital stock (other than Common Stock), stock or other
securities of other persons, evidences of indebtedness issued by the Corporation
or other persons, assets (excluding cash dividends) or options or rights
(excluding options to purchase and rights to subscribe for Common Stock or other
securities of the Corporation convertible into or exchangeable for Common
Stock), then, in each such case, the holders of shares of Preferred Stock shall,
concurrent with the distribution to holders of Common Stock, receive a like
distribution based upon the number of shares of Common Stock into which such
shares of Preferred Stock are convertible.

                        (vi) In case, at any time after the date hereof, of any
capital reorganization, or any reclassification of the stock of the Corporation
(other than as a result of a stock dividend or subdivision, split-up or
combination of shares), or the consolidation or merger of the Corporation with
or into another person (other than a consolidation or merger in which the
Corporation is the continuing entity and which does not result in any change in
the Common Stock), or of the sale or other disposition of all or substantially
all the properties and assets of the Corporation, the shares of Preferred Stock
shall, after such reorganization, reclassification, consolidation, merger, sale
or other disposition, be convertible into the kind and number of shares of stock
or other securities or property of the Corporation or otherwise to which such
holder would have been entitled if immediately prior to such reorganization,
reclassification, consolidation, merger, sale or other disposition he had
converted his shares of Preferred Stock into Common Stock. The provisions of
this clause (vi) shall similarly apply to successive reorganizations,
reclassifications, consolidations, mergers, sales or other dispositions.

                        (vii) All calculations under this Section 3 shall be
made to the nearest cent or to the nearest one hundredth (1/100) of a share, as
the case may be.

                        (viii) For the purpose of any computation pursuant to
this Section 3(e), the "Current Market Price" at any date of one share of Common
Stock, shall be deemed to be the average of the highest reported bid and the
lowest reported offer prices on the preceding business day as furnished by the
National Quotation Bureau, Incorporated (or equivalent recognized source of
quotations); provided, however, that if the Common Stock is not traded in such
manner that the quotations referred to in this clause (viii) are available for
the period required hereunder, Current Market Price shall be determined in good
faith by the Board of Directors of the Corporation, but if challenged by the
holders of more than 50% of the outstanding Series A Preferred, Series B
Preferred, Series C Preferred and Series D Preferred, voting as separate
classes, then as determined by an independent appraiser selected by the Board of
Directors of the Corporation, the cost of such appraisal to be borne equally by
the Corporation and the challenging parties.

            (f) Minimal Adjustments. No adjustment in the Conversion Price need
be made if such adjustment would result in a change in the Conversion Price of
less than $0.01. Any adjustment of less than $0.01 which is not made shall be
carried forward and shall be made at the time of and together with any
subsequent adjustment which, on a cumulative basis, amounts to an adjustment of
$0.01 or more in the Conversion Price.


                                      -9-
<PAGE>

            (g) No Impairment. Without the consent of the majority of the
outstanding shares of Preferred Stock, the Corporation will not through any
reorganization, recapitalization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms to be observed
or performed hereunder by the Corporation, but will at all times in good faith
assist in the carrying out of all the provisions of this Section 3 and in the
taking of all such action as may be necessary or appropriate in order to protect
the Conversion Rights of the holders of Preferred Stock against impairment.

            (h) Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Conversion Rate pursuant to this Section 3,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Preferred Stock a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon written request at any time
of any holder of Preferred Stock, furnish or cause to be furnished to such
holder a like certificate setting forth (i) such adjustments and readjustments,
(ii) the Conversion Rate of such series at the time in effect, and (iii) the
number of shares of Common Stock and the amount, if any, of other property which
at the time would be received upon the conversions of such holder's shares of
Preferred Stock.

            (i) Notices of Record Date. In the event of any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property or to receive any other right, the Corporation
shall mail to each holder of Preferred Stock at least ten (10) days prior to
such record date, a notice specifying the date on which any such record is to be
taken for the purpose of such dividend or distribution or right, and the amount
and character of such dividend, distribution or right.

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

            (k) Notices. Any notice required by the provisions of this Section 3
to be given to the holder of shares of Preferred Stock shall be deemed given if
deposited in the United States mail, postage prepaid, and addressed to each
holder of record at his address appearing on the books of the Corporation.


                                      -10-
<PAGE>

            (l) Reissuance of Converted Shares. No shares of Preferred Stock
which have been converted into Common Stock after the original issuance thereof
shall ever again be reissued and all such shares so converted shall upon such
conversion cease to be a part of the authorized shares of the Corporation.

            (m) Special Adjustment of Conversion Price for Qualified Public
Offering. Notwithstanding Section 3(a) above, in the event the Series D
Preferred is automatically converted into Common Stock by reason of a Qualified
Public Offering as set forth in Section 3(b) hereof, and the initial public
offering price per share (the "IPO Price") is less than 125% of the Original
Issue Price of the Series D Preferred (adjusted for stock splits and the like),
then the Conversion Price per share of Series D Preferred shall be reduced to a
number equal to the quotient of (i) the Conversion Price of the Series D
Preferred in effect immediately prior to such offering divided by (ii) a
fraction, the numerator of which is the Original Issue Price of the Series D
Preferred multiplied by 1.25 and the denominator of which is the IPO Price.

      4. Voting Rights. The holder of each share of Preferred Stock shall be
entitled to the number of votes equal to the number of shares of Common Stock
into which each share of Preferred Stock could be converted on the record date
for the vote or consent of shareholders written consent and, except as otherwise
required by law or provided for herein, shall have voting rights and powers
equal to the voting rights and powers of the Common Stock. The holder of each
share of Preferred Stock shall be entitled to notice of any shareholders'

      7. Series B Preferred - Right of Redemption.

            (a) Subject to Section 8(e) herein, the Corporation shall be
obligated to redeem the Series B Preferred as follows:

                  (i) At any time after March 31, 2004, the holders of a
majority of the then outstanding shares of Series B Preferred (the "Series B
Initiating Holders") may require the Corporation to the extent it may lawfully
do so, to redeem all of the outstanding Series B Preferred in three (3) equal
annual installments with the first installment date being the date forty-five
(45) days after receipt by the Corporation of the Series B Exercise Notice (as
defined below), the second installment being the date one (1) year from the
first installment date and the last installment date being a date two (2) years
from such first installment date (each a "Series B Redemption Date"). The
Corporation shall effect such redemptions on the applicable Series B Redemption
Date by paying in cash in exchange for each share of Series B Preferred to be
redeemed on each applicable Series B Redemption Date a sum equal to the fair
market value per share of Series B Preferred as of the date of receipt by the
Corporation of the Series B Exercise Notice plus all accrued and unpaid
dividends thereon. The fair market value per share of Series B Preferred for the
purposes of this Section 8, shall be determined by the Board of Directors of the
Corporation. If such determination is unacceptable to the holders of a majority
of the Series B Preferred, then the fair market value per share of Series B
Preferred shall be determined by an investment banking firm mutually acceptable
to the Corporation and the holders of a majority of the Series B Preferred. The
Series B Initiating


                                      -13-
<PAGE>

Holders shall have the right to revoke a Series B Exercise Notice by giving
written notice to the Corporation within fifteen (15) days after their receipt
of the Series B Redemption Notice (as defined below). The total amount to be
paid for the Series B Preferred is hereinafter referred to as the "Series B
Redemption Price." The number of shares of Series B Preferred that the
Corporation shall be required to redeem on any one Series B Redemption Date
shall be equal to the amount determined by dividing (i) the aggregate number of
shares of Series B Preferred outstanding immediately prior to the Series B
Redemption Date by (ii) the number of remaining Series B Redemption Dates
(including the Series B Redemption Date to which such calculation applies).
Shares subject to redemption pursuant to this Section 8(a) shall be redeemed
from each holder of Series B Preferred on a pro rata basis.

                  (ii) At any time after March 31, 2004, the Series B Initiating
Holders can elect to exercise the right of first redemption pursuant to this
Section 8(a) by providing written notice (the "Series B Exercise Notice") to the
Corporation. Within fifteen (15) days after the receipt of the Series B Exercise
Notice, the Corporation shall (i) send a notice (a "Series B Redemption Notice")
to each holder of record of the Series B Preferred to be redeemed at the address
of such holder appearing on the books of the Corporation setting forth (a) the
Series B Redemption Price for the shares to be redeemed and (b) the place at
which such holders may obtain payment of the Series B Redemption Price upon
surrender of their share certificates, and (ii) send a notice to each holder of
record of the Series C Preferred at the address of such holder appearing on the
books of the Corporation notifying such holders of the election of the holders
of the Series B Preferred to exercise the right of redemption of the Series B
Preferred. If the Corporation does not have sufficient funds legally available
to redeem all shares to be redeemed at any Series B Redemption Date (including,
if applicable, those to be redeemed at the option of the Corporation), then it
shall redeem such shares pro rata (based on the portion of the aggregate Series
B Redemption Price payable to them) to the extent possible and shall redeem the
remaining shares to be redeemed as soon as sufficient funds are legally
available.

            (b) On each Series B Redemption Date, the Corporation shall deposit
the portion of the Series B Redemption Price sufficient to redeem the shares to
be redeemed upon such Series B Redemption Date with a bank or trust corporation
having aggregate capital and surplus in excess of $100,000,000, as a trust fund,
with irrevocable instructions and authority to the bank or trust corporation to
pay, on and after such Series B Redemption Date, the applicable portion of the
Series B Redemption Price to their respective holders upon the surrender of
their share certificates. Any monies deposited by the Corporation pursuant to
this Section 8(b) for the redemption of shares thereafter converted into shares
of Common Stock pursuant to Section 3 hereof no later than the fifth (5th) day
preceding the applicable Series B Redemption Date shall be returned to the
Corporation forthwith upon such conversion. The balance of any funds deposited
by the Corporation pursuant to this Section 8(b) remaining unclaimed at the
expiration of one (1) year following such Series B Redemption Date shall be
returned to the Corporation.

            (c) On or after such Series B Redemption Date, each holder of shares
of Series B Preferred to be redeemed shall surrender such holder's certificates
representing such shares to the Corporation in the manner and at the place
designated in the Redemption Notice, and thereupon the


                                      -14-
<PAGE>

applicable portion of the Series B Redemption Price of such shares shall be
payable to the order of the person whose name appears on such certificate or
certificates as the owner thereof and each surrendered certificate shall be
canceled. In the event less than all the shares represented by such certificates
are redeemed, a new certificate shall be issued representing the unredeemed
shares. From and after the date the Corporation deposits funds pursuant to
Section 8(b) hereof with respect to shares to be redeemed on such Series B
Redemption Date, unless there shall have been a default in payment of the
applicable portion of the Series B Redemption Price or the Corporation is unable
to pay the applicable portion of the Series B Redemption Price due to not having
sufficient legally available funds, all rights of the holders of such shares as
holders of Series B Preferred (except the right to receive the Series B
Redemption Price without interest upon surrender of their certificates), shall
cease and terminate with respect to such shares, provided that in the event that
shares of Series B Preferred are not redeemed due to a default in payment by the
Corporation or because the Corporation does not have sufficient legally
available funds, such shares of Series B Preferred shall remain outstanding and
shall be entitled to all of the rights and preferences provided herein.

            (d) In the event of a call for redemption of any shares of Series B
Preferred, the Conversion Rights (as defined in Section 3) for the shares of
Series B Preferred to be redeemed on a particular Series B Redemption Date shall
terminate at the close of business on the fifth (5th) day preceding such Series
B Redemption Date, unless default is made in payment of the Series B Redemption
Price.

            (e) In the event that the Series B Initiating Holders have elected
to exercise their right of redemption pursuant to this Section 8 and to the
extent that the Company receives the Series C Exercise Notice (as defined below)
from the Series C Initiating Holders (as defined below) or the Series D Exercise
Notice (as defined below) from the Series D Initiating Holders (as defined
below) prior to the deposit by the Company of funds pursuant to Section 8(b)
hereof with respect to any applicable Series B Redemption Date, the right of
redemption of the Series C Preferred and the Series D Preferred shall be
superior and in preference to the right of redemption of the Series B Preferred
and the holders of the Series C Preferred and Series D Preferred shall be
entitled to receive the full amount of the Series C Redemption Price and the
Series D Redemption Price out of legally available funds of the Corporation
prior to the payment of any portion of the Series B Redemption Price not
previously deposited by the Company pursuant to Section 8(b) or required to be
paid to the holders of the Series B Preferred pursuant to the last sentence of
Section 8(a)(ii) hereof. In such event, after the full amount of the Series C
Redemption Price and the Series D Redemption Price has been deposited pursuant
to Sections 9(b) and 10(b) below, the holders of the Series B Preferred shall be
entitled to receive the full amount of the Series B Redemption Price of the
Series B Preferred. If the funds of the Corporation legally available for
redemption of shares of the Series B Preferred, Series C Preferred or Series D
Preferred are insufficient to redeem the total number of shares of Series B
Preferred, Series C Preferred or Series D Preferred to be redeemed on a Series B
Redemption Date, Series C Redemption Date or Series D Redemption Date, those
funds which are legally available will be used to redeem the maximum possible
number of such shares from first the holders of the Series C Preferred and
Series D Preferred to the extent of the full amount of the Series C Redemption
Price and Series D Redemption Price pro rata based on the relative redemption
price of such series and next to the holders of the Series B Preferred to the
extent of the full amount


                                      -15-
<PAGE>

of the Series B Redemption Price. The shares of Series B Preferred, Series C
Preferred or Series D Preferred not redeemed, as the case may be, shall remain
outstanding and entitled to all the rights and preferences provided herein,
including the rights of conversion set forth in Section 3. At any time
thereafter when additional funds of the Corporation are legally available for
the redemption of shares of Series B Preferred, Series C Preferred or Series D
Preferred, as the case may be, such funds will immediately be used to redeem the
balance of the shares which the Corporation has become obliged to redeem on any
Redemption Date but which it has not redeemed.

      8. Series C Preferred - Right of Redemption.

            (a) Subject to Section 8(e) above, the Corporation shall be
obligated to redeem the Series C Preferred as follows:

                  (i) Beginning on or after March 31, 2004, the holders of 66
2/3% of the then outstanding shares of Series C Preferred (the "Series C
Initiating Holders") may require the Corporation to the extent it may lawfully
do so, to redeem all of the outstanding Series C Preferred. Such redemption
shall occur on the 45th day following the Corporation's receipt of the Series C
Exercise Notice (as defined below) (such date being herein referred to as the
"Initial Series C Redemption Date"), provided that the Series C Initiating
Holders shall have the right to revoke a Series C Exercise Notice by giving
written notice to the Corporation within fifteen (15) days after their receipt
of the Series C Redemption Notice, and provided further that in lieu of
redeeming all of the Series C Preferred on the Initial Series C Redemption Date
the Corporation shall have the right to redeem the Series C Preferred in three
(3) equal installments, with the first installment date being the Initial Series
C Redemption Date, the second installment being the first anniversary of the
Initial Series C Redemption Date and the last installment being the second
anniversary of the Initial Series C Redemption Date (the Initial Series C
Redemption Date and each of such other redemption dates being herein referred to
as a "Series C Redemption Date"). The Corporation shall effect such redemptions
on the applicable Series C Redemption Date by paying in cash in exchange for
each share of Series C Preferred to be redeemed on each applicable Series C
Redemption Date, a sum equal to the fair market value per share of Series C
Preferred as of the date of receipt by the Corporation of the Series C Exercise
Notice plus all accrued and unpaid dividends with respect to such shares thereon
plus interest at the rate of 10% per annum payable on the amount of the unpaid
Series C Redemption Price (as hereinafter defined) accruing from the Initial
Series C Redemption Date until paid. The fair market value per share of Series C
Preferred for the purposes of this Section 9, shall be determined by the Board
of Directors of the Corporation. If such determination is unacceptable to the
holders of a majority of the Series C Preferred, then the fair market value per
share of Series C Preferred shall be determined by an investment banking firm
mutually acceptable to the Corporation and the holders of a majority of the
Series C Preferred. The total amount to be paid for the Series C Preferred is
hereinafter referred to as the "Series C Redemption Price." The number of shares
of Series C Preferred that the Corporation shall be required to redeem on any
one Series C Redemption Date shall be equal to the amount determined by dividing
(i) the aggregate number of shares of Series C Preferred outstanding immediately
prior to the Series C Redemption Date by (ii) the number of remaining Series C
Redemption Dates (including the Series C


                                      -16-
<PAGE>

Redemption Date to which such calculation applies). Shares subject to redemption
pursuant to this Section 9(a) shall be redeemed from each holder of Series C
Preferred on a pro rata basis.

                  (ii) At any time after March 31, 2004, the Series C Initiating
Holders can elect to exercise the right of first redemption pursuant to this
Section 9(a) by providing written notice (the "Series C Exercise Notice") to the
Corporation. Within fifteen (15) days after the receipt of the Series C Exercise
Notice, the Corporation shall (i) send a notice (a Series C "Redemption Notice")
to each holder of record of the Series C Preferred to be redeemed at the address
of such holder appearing on the books of the Corporation setting forth (a) the
Series C Redemption Price for the shares to be redeemed and (b) the place at
which such holders may obtain payment of the Series C Redemption Price upon
surrender of their share certificates. If the Corporation does not have
sufficient funds legally available to redeem all shares to be redeemed at the
Series C Redemption Date (including, if applicable, those to be redeemed at the
option of the Corporation), then it shall redeem such shares pro rata (based on
the portion of the aggregate Series C Redemption Price payable to them) to the
extent possible and shall redeem the remaining shares to be redeemed as soon as
sufficient funds are legally available.

            (b) On or prior to the Series C Redemption Date, the Corporation
shall deposit the applicable portion of the Series C Redemption Price of the
shares to be redeemed on such Series C Redemption Date with a bank or trust
corporation having aggregate capital and surplus in excess of $100,000,000, as a
trust fund, with irrevocable instructions and authority to the bank or trust
corporation to pay, on and after such Series C Redemption Date, the applicable
portion of the Series C Redemption Price of the shares to their respective
holders upon the surrender of their share certificates. Any monies deposited by
the Corporation pursuant to this Section 9(b) for the redemption of shares
thereafter converted into shares of Common Stock pursuant to Section 3 hereof no
later than the fifth (5th) day preceding the Series C Redemption Date shall be
returned to the Corporation forthwith upon such conversion. The balance of any
funds deposited by the Corporation pursuant to this Section 9(b) remaining
unclaimed at the expiration of one (1) year following such Series C Redemption
Date shall be returned to the Corporation.

            (c) On or after such Series C Redemption Date, each holder of shares
of Series C Preferred to be redeemed shall surrender such holder's certificates
representing such shares to the Corporation in the manner and at the place
designated in the Series C Redemption Notice, and thereupon the applicable
portion of the Series C Redemption Price of such shares shall be payable to the
order of the person whose name appears on such certificate or certificates as
the owner thereof and each surrendered certificate shall be canceled. In the
event less than all the shares represented by such certificates are redeemed, a
new certificate shall be issued representing the unredeemed shares. >From and
after the date the Corporation deposits funds pursuant to Section 9(b) hereof
with respect to shares to be redeemed on such Series C Redemption Date, unless
there shall have been a default in payment of the applicable portion of the
Series C Redemption Price or the Corporation is unable to pay the applicable
portion of the Series C Redemption Price due to not having sufficient legally
available funds, all rights of the holders of such shares as holders of Series C
Preferred (except the right to receive the Series C Redemption Price without
interest upon surrender of their certificates), shall cease and terminate with
respect to such shares, provided that in the event that shares of


                                      -17-
<PAGE>

Series C Preferred are not redeemed due to a default in payment by the
Corporation or because the Corporation does not have sufficient legally
available funds, such shares of Series C Preferred shall remain outstanding and
shall be entitled to all of the rights and preferences provided herein.

            (d) In the event of a call for redemption of any shares of Series C
Preferred, the Conversion Rights (as defined in Section 3) for the shares of
Series C Preferred to be redeemed on a particular Series C Redemption Date shall
terminate at the close of business on the fifth (5th) day preceding such Series
C Redemption Date, unless default is made in payment of the Series C Redemption
Price.

      9. Series D Preferred - Right of Redemption.

            (a) Subject to Section 8(e) above, the Corporation shall be
obligated to redeem the Series D Preferred as follows:

                  (i) Beginning on or after March 31, 2004, the holders of 66
2/3% of the then outstanding shares of Series D Preferred (the "Series D
Initiating Holders") may require the Corporation to the extent it may lawfully
do so, to redeem all of the outstanding Series D Preferred. Such redemption
shall occur on the 45th day following the Corporation's receipt of the Series D
Exercise Notice (as defined below) (such date being herein referred to as the
"Initial Series D Redemption Date"), provided that the Series D Initiating
Holders shall have the right to revoke a Series D Exercise Notice by giving
written notice to the Corporation within fifteen (15) days after their receipt
of the Series D Redemption Notice, and provided further that in lieu of
redeeming all of the Series D Preferred on the Initial Series D Redemption Date
the Corporation shall have the right to redeem the Series D Preferred in three
(3) equal installments, with the first installment date being the Initial Series
D Redemption Date, the second installment being the first anniversary of the
Initial Series D Redemption Date and the last installment being the second
anniversary of the Initial Series D Redemption Date (the Initial Series D
Redemption Date and each of such other redemption dates being herein referred to
as a "Series D Redemption Date"). The Corporation shall effect such redemptions
on the applicable Series D Redemption Date by paying in cash in exchange for
each share of Series D Preferred to be redeemed on each applicable Series D
Redemption Date, a sum equal to the fair market value per share of Series D
Preferred as of the date of receipt by the Corporation of the Series D Exercise
Notice plus all accrued and unpaid dividends with respect to such shares thereon
plus interest at the rate of 10% per annum payable on the amount of the unpaid
Series D Redemption Price (as hereinafter defined) accruing from the Initial
Series D Redemption Date until paid. The fair market value per share of Series D
Preferred for the purposes of this Section 10, shall be determined by the Board

holders of a majority of the Series D Preferred, then the fair market value per
share of Series D Preferred shall be determined by an investment banking firm
mutually acceptable to the Corporation and the holders of a majority of the
Series D Preferred. The total amount to be paid for the Series D Preferred is
hereinafter referred to as the "Series D Redemption Price." The number of shares
of Series D Preferred that the Corporation shall be required to redeem on any
one Series D Redemption Date shall be equal to the amount determined by dividing
(i) the aggregate number of shares of Series D Preferred outstanding immediately
prior to the Series D Redemption


                                      -18-
<PAGE>

Date by (ii) the number of remaining Series D Redemption Dates (including the
Series D Redemption Date to which such calculation applies). Shares subject to
redemption pursuant to this Section 10(a) shall be redeemed from each holder of
Series D Preferred on a pro rata basis.

Section 10(a) by providing written notice (the "Series D Exercise Notice") to
the Corporation. Within fifteen (15) days after the receipt of the Series D
Exercise Notice, the Corporation shall (i) send a notice (a Series D "Redemption
Notice") to each holder of record of the Series D Preferred to be redeemed at
the address of such holder appearing on the books of the Corporation setting
forth (a) the Series D Redemption Price for the shares to be redeemed and (b)
the place at which such holders may obtain payment of the Series D Redemption
Price upon surrender of their share certificates. If the Corporation does not
have sufficient funds legally available to redeem all shares to be redeemed at
the Series D Redemption Date (including, if applicable, those to be redeemed at
the option of the Corporation), then it shall redeem such shares pro rata (based
on the portion of the aggregate Series D Redemption Price payable to them) to
the extent possible and shall redeem the remaining shares to be redeemed as soon
as sufficient funds are legally available.

            (b) On or prior to the Series D Redemption Date, the Corporation
shall deposit the applicable portion of the Series D Redemption Price of the
shares to be redeemed on such Series D Redemption Date with a bank or trust
corporation having aggregate capital and surplus in excess of $100,000,000, as a
trust fund, with irrevocable instructions and authority to the bank or trust
corporation to pay, on and after such Series D Redemption Date, the applicable
portion of the Series D Redemption Price of the shares to their respective
holders upon the surrender of their share certificates. Any monies deposited by
the Corporation pursuant to this Section 10(b) for the redemption of shares
thereafter converted into shares of Common Stock pursuant to Section 3 hereof no
later than the fifth (5th) day preceding the Series D Redemption Date shall be
returned to the Corporation forthwith upon such conversion. The balance of any
funds deposited by the Corporation pursuant to this Section 10(b) remaining
unclaimed at the expiration of one (1) year following such Series D Redemption
Date shall be returned to the Corporation.

            (c) On or after such Series D Redemption Date, each holder of shares
of Series D Preferred to be redeemed shall surrender such holder's certificates
representing such shares to the Corporation in the manner and at the place
designated in the Series D Redemption Notice, and thereupon the applicable
portion of the Series D Redemption Price of such shares shall be payable to the

the owner thereof and each surrendered certificate shall be canceled. In the
event less than all the shares represented by such certificates are redeemed, a
new certificate shall be issued representing the unredeemed shares. >From and
after the date the Corporation deposits funds pursuant to Section 10(b) hereof
with respect to shares to be redeemed on such Series D Redemption Date, unless
there shall have been a default in payment of the applicable portion of the
Series D Redemption Price or the Corporation is unable to pay the applicable
portion of the Series D Redemption Price due to not having sufficient legally
available funds, all rights of the holders of such shares as holders of Series D
Preferred (except the right to receive the Series D Redemption Price without
interest upon surrender of their certificates),


                                      -19-

event that shares of Series D Preferred are not redeemed due to a default in
payment by the Corporation or because the Corporation does not have sufficient
legally available funds, such shares of Series D Preferred shall remain
outstanding and shall be entitled to all of the rights and preferences provided
herein.

                  (d) In the event of a call for redemption of any shares of

                          INVENTA TECHNOLOGIES, INC.

     Inventa Technologies, Inc., a corporation organized and existing under the
laws of the State of Delaware, hereby certifies as follows:

     The Preferred Stock may be issued from time to time in one or more

or alter the rights, preferences, privileges and restrictions granted to or
imposed upon any wholly unissued series of Preferred Stock and to fix the number
of shares of any series of Preferred Stock and the designation of any such
series of Preferred Stock. The board of directors, within the limits and
restrictions stated in any resolution or resolutions of the board of directors
originally fixing the number of shares constituting any series, may increase or
decrease (but not below the number of shares of any such series then
outstanding) the number of shares of any series subsequent to the issue of
shares of that series.

     The authority of the board of directors with respect to each such class or
series shall include, without limitation of the foregoing, the right to
determine and fix:

          (a)  the distinctive designation of such class or series and the
number of shares to constitute such class or series;

          (b)  the rate at which dividends on the shares of such class or series
shall be declared and paid, or set aside for payment, whether dividends at the
rate so determined shall be cumulative or accruing, and whether the shares of
such class or series shall be entitled to any participating or other dividends
in addition to dividends at the rate so determined, and if so, on what terms;

          (c)  the right or obligation, if any, of the corporation to redeem
shares of the particular class or series of Preferred Stock and, if redeemable,
the price, terms and manner of such redemption;

          (d)  the special and relative rights and preferences, if any, and the
amount or amounts per share that the shares of such class or series of Preferred
Stock shall be entitled to receive upon any voluntary or involuntary
liquidation, dissolution or winding up of the corporation;

          (e)  the terms and conditions, if any, upon which shares of such class
or series shall be convertible into, or exchangeable for, shares of capital
stock of any other class or series, including the price or prices or the rate or
rates of conversion or exchange and the terms of adjustment, if any;

          (f)  the obligation, if any, of the corporation to retire, redeem or
purchase shares of such class or series pursuant to a sinking fund or fund of a
similar nature or otherwise, and the terms and conditions of such obligation;

                                      -2-

Stock;

          (h)  limitations, if any, on the issuance of additional shares of such
class or series or any shares of any other class or series of Preferred Stock;
and

          (i)  such other preferences, powers, qualifications, special or
relative rights and privileges thereof as the board of directors of the
corporation, acting in accordance with this Restated Certificate of
Incorporation, may deem advisable and are not inconsistent with law and the
provisions of this Restated Certificate of Incorporation.

such holder would be entitled to cast for the election of directors with respect
to his shares of stock multiplied by the number of directors to be elected by
him, and the holder may cast all of such votes for a single director or may

      The annual meeting of stockholders shall be held each year on a date and
at a time designated by the board of directors. In the absence of such

<PAGE>

      2.3 SPECIAL MEETING

      A special meeting of the stockholders may be called, at any time for any
purpose or purposes, by the board of directors.

      2.4 NOTICE OF STOCKHOLDERS' MEETINGS

      All notices of meetings with stockholders shall be in writing and shall be
sent or otherwise given in accordance with Section 2.5 of these bylaws not less
than ten (10) nor more than sixty (60) days before the date of the meeting to
each stockholder entitled to vote at such meeting. The notice shall specify the
place, date, and hour of the meeting, and, in the case of a special meeting, the
purpose or purposes for which the meeting is called.

      2.5 MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE

      Written notice of any meeting of stockholders, if mailed, is given when
deposited in the United States mail, postage prepaid, directed to the
stockholder at his address as it appears on the records of the corporation. An
affidavit of the secretary or an assistant secretary or of the transfer agent of
the corporation that the notice has been given shall, in the absence of fraud,
be prima facie evidence of the facts stated therein.

      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 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

might have been transacted at the original meeting. If the adjournment is for
more than thirty (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.

<PAGE>

      2.8 VOTING

      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).

      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.

      2.9 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 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.

      2.10 RECORD DATE FOR STOCKHOLDER NOTICE; VOTING; GIVING CONSENTS

      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 sixty (60) nor less than ten (10) days before the date of such

of or to vote at a meeting of stockholders shall be at the close of business on

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 entitled to express

      Each stockholder entitled to vote at a meeting of stockholders or to
express consent or dissent to corporate action may authorize another person or
persons to act for him 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 (3) 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(c) of the General Corporation Law of
Delaware.

alphabetical order, and showing the address of each stockholder and the number
of shares registered in the name of each stockholder. Such list shall be open to
the examination of any stockholder, for any purpose germane to the meeting,
during ordinary business hours, for a period of at least ten (10) days prior to
the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

      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 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.


                                      -4-
<PAGE>

      3.2 NUMBER OF DIRECTORS

      The board of directors shall consist of seven (7) members. The number of
directors may be changed by an amendment to this bylaw, duly adopted by the
board of directors or by the stockholders, or by a duly adopted amendment to the
certificate of incorporation. Upon the closing of the first sale of the
corporation's common stock pursuant to a firmly underwritten registered public
offering (the "IPO"), the directors shall be divided into three classes, with
the term of office of the first class, which class shall initially consist of
_____ directors, to expire at the first annual meeting of stockholders held
after the IPO; the term of office of the second class, which shall initially
consist of _____ directors, to expire at the second annual meeting of
stockholders held after the IPO; the term of office of the third class, which
class shall initially consist of ____ directors, to expire at the third annual
meeting of stockholders held after the IPO; and thereafter for each such term to
expire at each third succeeding annual meeting of stockholders held after such
election.

      No reduction of the authorized number of directors shall have the effect
of removing any director before that 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 successor is elected and qualified or
until his earlier resignation or removal.

      Elections of directors need not be by written ballot.

      3.4 RESIGNATION AND VACANCIES

      Any director may resign at any time upon written notice to 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.

      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.


                                      -5-
<PAGE>

            (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
(as constituted immediately prior to any such increase), then the Court of
Chancery may, upon application of any stockholder or stockholders holding at
least ten (10) percent 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 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 FIRST MEETINGS

      The first meeting of each newly elected board of directors shall be held
at such time and place as shall be fixed by the vote of the stockholders at the
annual meeting and no notice of such meeting shall be necessary to the newly
elected directors in order legally to constitute the meeting, provided a quorum
shall be present. In the event of the failure of the stockholders to fix the
time or place of such first meeting of the newly elected board of directors, or
in the event such meeting is not held at the time and place so fixed by the
stockholders, the meeting may be held at such time and


                                      -6-

      Special meetings of the board may be called by the president on three (3)
days' notice to each director, either personally or by mail, telegram, telex, or
telephone; special meetings shall be called by the president or secretary in
like manner and on like notice on the written request of two (2) directors
unless the board consists of only one (1) director, in which case special
meetings shall be called by the president or secretary in like manner and on
like notice on the written request of the sole director.

      3.9 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.

      3.10 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 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.

      3.11 ADJOURNED MEETING; NOTICE

      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

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 contained in this section shall be deemed to
deny, limit or restrict the powers of guaranty or warranty of the corporation at
common law or under any statute.

      3.15 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

of removing any director prior to the expiration of such director's term of
office.

whole board, designate one or more committees, with each committee to consist of
one or more of the directors of the corporation. The board may designate one or
more directors as alternate members of any committee, who may replace any absent

disqualification of a member of a committee, the member or members thereof
present at any

meeting and not disqualified from voting, whether or not he or they constitute a
quorum, may unanimously appoint another member of the board of directors to act

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 (i) 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
any of the preferences or rights of such shares relating to dividends,

a certificate of ownership and merger pursuant to Section 253 of the General
Corporation Law of Delaware.

officer of the corporation, (ii) who is or was serving at the request of the
corporation as a director or officer of another corporation, partnership, joint
venture, trust or other enterprise, or (iii) who was a director or officer of a

upon written demand under oath stating the purpose thereof, have the right
during the usual hours for business to inspect for any proper purpose the
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.

      The officer who has charge of the stock ledger of a corporation shall

the meeting, either at a place within the city where the meeting is to be held,
which place shall be specified in the notice of the meeting, or, if not so
specified, at the place where the meeting is to be held. The list shall also be
produced and kept at the time and place of the meeting during the whole time
thereof, and may be inspected by any stockholder who is present.

      7.2 INSPECTION BY DIRECTORS

      Any director shall have the right to examine the corporation's stock
ledger, a list of its stockholders, and its other books and records for a
purpose reasonably related to his 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.

      7.4 REPRESENTATION OF SHARES OF OTHER CORPORATIONS

      The chairman of the board, the president, any vice president, the
treasurer, the secretary or assistant secretary of this corporation, or any
other person authorized by the board of directors or the president or a vice
president, is authorized to vote, represent, and exercise on behalf of this
corporation all rights incident to any and all shares of any other corporation

                                 GENERAL MATTERS

      8.1 CHECKS

      From time to time, the board of directors shall determine by resolution
which person or persons may sign or endorse all checks, drafts, other orders for
payment of money, notes or other evidences of indebtedness that are issued in
the name of or payable to the corporation, and only the persons so authorized
shall sign or endorse those instruments.

      8.2 EXECUTION OF CORPORATE CONTRACTS AND INSTRUMENTS

      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.
Unless so authorized or ratified by the board of directors or within the agency
power of an officer, no officer, agent or employee shall have any power or
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 a 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


                                      -15-
<PAGE>

the board of directors, or the president or vice-president, and by the treasurer
or an assistant treasurer, or the secretary or an assistant secretary of such
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 were such officer, transfer agent or
registrar at the date of issue.

      The corporation may issue the whole or any part of its shares as 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 or
more than one series of any class, then 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 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.

      8.5 LOST CERTIFICATES

      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 cancelled at the same time. The corporation
may issue a new certificate of stock or uncertificated shares in the place of
any certificate theretofore 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 his legal representative, to give the corporation a
bond sufficient to 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.

      Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the Delaware General Corporation Law shall

the certificate of incorporation, may declare and pay dividends upon the shares
of its capital stock pursuant to the General Corporation Law of Delaware.
Dividends may be paid in cash, in property, or in shares of the corporation's
capital stock.

      The directors of the corporation may set apart out of any of the funds 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 be
limited to equalizing dividends, repairing or maintaining any property of the
corporation, and meeting contingencies.

corporation to issue a new certificate to the person entitled 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 agreement

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

<PAGE>

      The corporation shall be entitled to recognize the exclusive right of 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
share or shares on the part of another person, whether or not it shall have
express or other notice thereof, except as otherwise provided by the laws of
Delaware.

                                   ARTICLE IX

                                   AMENDMENTS

      The original or other bylaws of the corporation may be adopted, amended or
repealed by the stockholders entitled to vote; provided, however, that the
corporation may, in its certificate of incorporation, confer the power to adopt,
amend or repeal bylaws upon the directors. The fact that such power has been so
conferred upon the directors shall not divest the stockholders of the power, nor
limit their power to adopt, amend or repeal bylaws.

                                   ARTICLE X

                                   DISSOLUTION

      If it should be deemed advisable in the judgment of the board of directors
of the corporation that the corporation should be dissolved, the board, after
the adoption of a resolution to that effect by a majority of the whole board at
any meeting called for that purpose, shall cause notice to be mailed to each
stockholder entitled to vote thereon of the adoption of the resolution and of a
meeting of stockholders to take action upon the resolution.

      At the meeting a vote shall be taken for and against the proposed
dissolution. If a majority of the outstanding stock of the corporation entitled
to vote thereon votes for the proposed dissolution, then a certificate stating
that the dissolution has been authorized in accordance with the provisions of
Section 275 of the General Corporation Law of Delaware and setting forth the
names and residences of the directors and officers shall be executed,
acknowledged, and filed and shall become effective in accordance with Section
103 of the General Corporation Law of Delaware. Upon such certificate's becoming
effective in accordance with Section 103 of the General Corporation Law of
Delaware, the corporation shall be dissolved.

      Whenever all the stockholders entitled to vote on a dissolution consent in
writing, either in person or by duly authorized attorney, to a dissolution, no
meeting of directors or stockholders shall be necessary. The consent shall be
filed and shall become effective in accordance with Section 103 of the General
Corporation Law of Delaware. Upon such consent's becoming effective in
accordance with Section 103 of the General Corporation Law of Delaware, the
corporation shall be dissolved. If the consent is signed by an attorney, then
the original power of attorney or a photocopy thereof shall be attached to and
filed with the consent. The consent filed with the Secretary of State


                                      -18-
<PAGE>

shall have attached to it the affidavit of the secretary or some other officer
of the corporation stating that the consent has been signed by or on behalf of
all the stockholders entitled to vote on a dissolution; in addition, there shall
be attached to the consent a certification by the secretary or some other
officer of the corporation setting forth the names and residences of the
directors and officers of the corporation.

      11.1 APPOINTMENT OF A CUSTODIAN IN CERTAIN CASES

      The Court of Chancery, upon application of any stockholder, may appoint
one or more persons to be custodians and, if the corporation is insolvent, to be
receivers, of and for the corporation when:

            (a) at any meeting held for the election of directors the
stockholders are so divided that they have failed to elect successors to
directors whose terms have expired or would have expired upon qualification of
their successors; or

            (b) the business of the corporation is suffering or is threatened
with irreparable injury because the directors are so divided respecting the
management of the affairs of the corporation that the required vote for action
by the board of directors cannot be obtained and the stockholders are unable to
terminate this division; or

            (c) the corporation has abandoned its business and has failed within
a reasonable time to take steps to dissolve, liquidate or distribute its assets.

      11.2 DUTIES OF CUSTODIAN

      The custodian shall have all the powers and title of a receiver appointed
under Section 291 of the General Corporation Law of Delaware, but the authority
of the custodian shall be to continue the business of the corporation and not to
liquidate its affairs and distribute its assets, except when the Court of
Chancery otherwise orders and except in cases arising under Sections 226(a)(3)
or 352(a)(2) of the General Corporation Law of Delaware.

          THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
          INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933, AS AMENDED, (THE "ACT") OR ANY STATE SECURITIES LAWS.  SUCH
          SHARES MAY NOT BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF SUCH
          REGISTRATION OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND
          ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE ACT.
          COPIES OF THE AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND
          RESTRICTING THEIR TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN
          REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE
          SECRETARY OF THE CORPORATION AT THE PRINCIPAL EXECUTIVE OFFICE OF THE
          CORPORATION.

          Upon request of a holder of such a certificate, the Company shall
remove the foregoing legend from the certificate or issue to such holder a new
certificate therefor free of any transfer legend, if, with such request, the
Company shall have received either the opinion referred to in Section 4(i) or
the "no-action" letter referred to in Section 4(ii) to the effect that any
transfer by such holder of the securities evidenced by such certificate will not
violate the Securities Act and applicable state securities laws, unless any such
transfer legend may be removed pursuant to Rule 144(k), in which case no such
opinion or "no-action" letter shall be required, and provided that the Company
shall not be obligated to remove any such legends prior to the date of the
initial public offering of the Company's Common Stock under the Securities Act.

     4.   Notice of Proposed Transfers.  The holder of each certificate
          ----------------------------
representing Restricted Securities by acceptance thereof agrees to comply in all
respects with the provisions of this Section 4. Prior to any proposed transfer
of any Restricted Securities (other than under circumstances described in
Sections 5, 6 and 8 hereof), the holder thereof shall give written notice to the
Company of such holder's intention to effect such transfer.  Each such notice
shall describe the manner and circumstances of the proposed transfer in
sufficient detail, and shall be accompanied (except in transactions in
compliance with Rule 144 promulgated under the Securities Act or for a transfer
to a holder's spouse, ancestors, descendants or a trust for any of their
benefit, or in

                                       3
<PAGE>

transactions involving the distribution without consideration of Restricted
Securities by a holder that is a partnership to any of its partners or retired
partners or to the estate of any of its partners or retired partners, or by a
holder that is a trust to any successor trust or successor trustee) by either
(i) a written opinion of legal counsel to the holder who shall be reasonably
satisfactory to the Company, addressed to the Company and reasonably
satisfactory in form and substance to the Company's counsel, to the effect that
the proposed transfer of the Restricted Securities may be effected without
registration under the Securities Act or (ii) a "no-action" letter from the
Commission to the effect that the distribution of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such
Restricted Securities shall be entitled to transfer such Restricted Securities
in accordance with the terms of the notice delivered by such holder to the
Company. Each certificate evidencing the Restricted Securities transferred as
above provided shall bear the restrictive legend set forth in Section 3 above,
except that such certificate shall not bear such restrictive legend after the
date of the Company's initial public offering under the Securities Act if the
opinion of counsel or "no-action" letter referred to above expressly indicates
that such legend is not required in order to establish compliance with the
Securities Act or if such legend is no longer required pursuant to Rule 144(k).

     5.   Demand Registration.
          -------------------

          (a)  Request for Registration.  If the Company shall receive from
               ------------------------
Initiating Holders a written request that the Company effect any registration
with respect to the Registrable Securities, the Company will:

               (i)  promptly given written notice of the proposed registration
to all other Holders; and

               (ii) as soon as practicable, use its diligent best efforts to
effect such registration after January 1, 2000 (including, without limitation,
the execution of an undertaking to file post effective amendments, appropriate
qualification under applicable blue sky or other state securities laws and
appropriate compliance with applicable regulations issued under the Securities
Act) as may be so requested and as would permit or facilitate the sale and
distribution of all or such portion of such Registrable Securities as are
specified in such request, together with all or such portion of the Registrable
Securities of any Holder or Holders joining in such request as are specified in
a written request delivered to the Company within fifteen (15) days after
receipt of such written notice from the Company; provided that the Company shall
not be obligated to effect, or to take any action to effect, any such
registration pursuant to this Section 5:

                    (A)  In any particular jurisdiction in which the Company
would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance, unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act;

                    (B)  After the Company has effected two (2) such
registrations pursuant to this Section 5(a) and such registrations have been
declared or ordered effective, or withdrawn at the request of the majority of
the Initiating Holders, and the sales of such Registrable Securities have
closed; or

                                       4
<PAGE>

                    (C)  Within one hundred eighty (180) days of the effective
date of any other registration statement on Form S-1.

          Subject to the foregoing clauses (A), (B) and (C), the Company shall
file a registration statement covering the Registrable Securities so requested
to be registered as soon as practicable, after receipt of the request or
requests of the Initiating Holders; provided, however, that if the Company shall
furnish to such Holders a certificate signed by the President of the Company
stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its shareholders
for such registration statement to be filed on or before the time filing would
be required and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer such filing
(but not more than once during any twelve month period) for a period of not more
than ninety (90) days after receipt of the request of the Initiating Holders.

          The registration statement filed pursuant to the request of the
Initiating Holders, may, subject to the provisions of Section 5(b) below,
include other securities of the Company which are held by officers or directors
of the Company or which are held by persons who, by virtue of agreements with
the Company, are entitled to include their securities in any such registration,
but the Company shall have no right to include any of its securities in any such
registration except as provided in Section 5(b) below.

          (b)  Underwriting.  If the Initiating Holders intend to distribute the
               ------------
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
Section 5, and the Company shall include such information in the written notice
referred to in Section 5(a)(i) above. The right of any Holder to registration
pursuant to Section 5 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting (unless otherwise mutually agreed by a majority-in-interest of
the Initiating Holders and such Holder with respect to such participation and
inclusion) to the extent provided herein. A Holder may elect to include in such
underwriting all or a part of the Registrable Securities he holds.

          If officers or directors of the Company shall request inclusion of
securities of the Company other than Registrable Securities in any registration
pursuant to Section 5, or if holders of securities of the Company who are
entitled by contract with the Company to have securities included in such a
registration (such officers, directors, and other shareholders being
collectively referred to as the "Other Shareholders") request such inclusion,
the Initiating Holders shall, on behalf of all Holders, offer to include the
securities of such Other Shareholders in the underwriting and may condition such
offer on their acceptance of the further applicable provisions of this
Agreement. The Company shall (together with all Holders and Other Shareholders
proposing to distribute their securities through such underwriting) enter into
an underwriting agreement in customary form with the representative of the
underwriter or underwriters (the "Underwriter") selected for such underwriting
by more than fifty percent (50%) of the Initiating Holders and reasonably
acceptable to the Company. Notwithstanding any other provision of this Section
5, if the Underwriter determines that marketing factors require a limitation on
the number of shares to be underwritten, the Underwriter may (subject to the
allocation priority set forth below) limit the number of Registrable Securities
to be included in the registration and underwriting to not less than fifty
percent (50%) of

                                       5
<PAGE>

the securities which Holders have requested be included therein. The Company
shall so advise all holders of securities requesting registration, and the
number of shares of securities that are entitled to be included in the
registration and underwriting shall be allocated in the following priority:
first, among all Holders of Registrable Securities requesting inclusion (and pro
rata among such holders on the basis of all Registrable Securities then held by
such holders); and second, among all Other Shareholders in proportion, as nearly
as practicable, to the respective amounts of securities which they had requested
to be included in such registration at the time of filing the registration
statement. If any Holder or Other Shareholder disapproves of the terms of any
such underwriting, such holder may elect to withdraw therefrom by written notice
to the Company and the Underwriter. Any Registrable Securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration. If
the Underwriter has not limited the number of Registrable Securities or other
securities to be underwritten, the Company may include its securities for its
own account in such registration if the underwriter so agrees and if the number
of Registrable Securities and other securities which would otherwise have been
included in such registration and underwriting will not thereby be limited.

     6.   Company Registration.
          --------------------

          (a)  If the Company shall determine to register any of its securities
either for its own account or for the account of a security holder or holders
exercising their respective demand registration rights, other than a
registration relating solely to employee benefit plans or a registration
relating solely to a Commission Rule 145 transaction or a registration on any
registration form which does not permit secondary sales or does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of Registrable Securities, the Company
will:

               (i)  promptly give to each Holder written notice thereof (which,
to the extent then known, shall include a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under the applicable blue
sky or other state securities laws); and

               (ii) include in such registration (and any related qualification
under blue sky laws or other compliance), and in any underwriting involved
therein, all of the Registrable Securities specified in a written request or
requests made by any Holder within fifteen (15) days after receipt of the
written notice from the Company described in clause (i) above, except as set
forth in Section 6(b) below. Such written request may specify all or a part of a
Holder's Registrable Securities.

          (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 a part of the written notice given
pursuant to Section 6(a)(i). In such event the right of any Holder to
registration pursuant to Section 6 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of such Holder's
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 Shareholders distributing their
securities through such underwriting) enter into an underwriting agreement in
customary form with the Underwriter selected for underwriting by the Company.
Notwithstanding any other provision of

                                       6
<PAGE>

this Section 6, if the Underwriter determines that marketing factors require a
limitation on the number of shares to be underwritten, and (a) if such
registration is the first registered offering of the Company's securities to the
public, the Underwriter may (subject to the allocation priority set forth below)
exclude from such registration and underwriting some or all of the Registrable
Securities which would otherwise be underwritten pursuant hereto, and (b) if
such registration is other than the first registered offering of the sale of the
Company's securities to the public, the Underwriter may (subject to the
allocation priority set forth below) limit the number of Registrable Securities
to be included in the secondary portion of the registration and underwriting to
not less than fifty percent (50%) of the securities which Holders have requested
be included therein. The Company shall so advise all holders of securities
requesting registration, and the number of shares of securities that are
entitled to be included in the registration and underwriting by persons other
than the Company shall be allocated in the following priority: first, to Holders
of Registrable Securities (and pro rata among such holders on the basis of all
Registrable Securities then held by such holders); and second, among all Other
Shareholders in proportion, as nearly as practicable, to the respective amounts
of securities which they had requested to be included in such registration at
the time of filing the registration statement. If any Holder or Other
Shareholder disapproves of the terms of any such underwriting, he may elect to
withdraw therefrom by written notice to the Company and the Underwriter. Any
Registrable Securities or other securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration.

     7.   Expenses of Registration.  All Registration Expenses incurred in
          ------------------------
connection with any registration, qualification or compliance pursuant to this
Agreement shall be borne by the Company, and all Selling Expenses shall be borne
by the holders of the securities so registered pro rata on the basis of the
number of their shares so registered; provided, however, that the Company shall
not be required to pay any Registration Expenses if, as a result of the
withdrawal of a request for registration by Initiating Holders, the registration
statement does not become effective, unless such withdrawal is caused by a
material adverse change in the business or operations of the Company after such
request for registration, or unless the Initiating Holders agree to have such
registration considered a registration pursuant to Section 5(a)(ii)(B). If the
Company is not required to pay any Registration Expenses, then the Holders and
Other Shareholders requesting registration shall bear such Registration Expenses
pro rata on the basis of the number of their shares so included in the
registration request, and such registration shall not be considered a
registration for purposes of Section 5(a)(ii)(B).

     8.   Registration on Form S-3.  The Company shall use its best efforts to
          ------------------------
qualify for registration on Form S-3, and to that end, the Company shall comply
with the reporting requirements of the Exchange Act following the effective date
of the first registration of any securities of the Company for a registered
public offering. After the Company has qualified for the use of Form S-3,
Initiating Holders shall have the right to request four (4) registrations on
Form S-3 (such requests shall be in writing and shall state the number of shares
of Registrable Securities to be disposed of and the intended method of
disposition of such shares by each such holder), subject only to the following
limitations:

          (a)  The Company shall not be obligated to cause a registration on
Form S-3 to become effective prior to one hundred eighty (180) days following
the effective date of a Company-

                                       7
<PAGE>

initiated registration (other than a registration effected solely to qualify an
employee benefit plan or to effect a business combination pursuant to Rule 145),
provided that notice of such Company-initiated registration is given to Holders
prior to receipt of a request from a holder of Registrable Securities for
registration on Form S-3, and provided that the Company shall use its best
efforts to achieve such effectiveness promptly following such one hundred eighty
(180) day period;

          (b)  The Company shall not be obligated to cause a registration on
Form S-3 to become effective prior to expiration of one hundred eighty (180)
days following the effective date of the most recent registration pursuant to a
request by a holder of Registrable Securities under this Agreement or pursuant
to a request by a holder of registration rights under any other agreement of the
Company granting Form S-3 demand registration rights; provided, however, that
the Company shall use its best efforts to achieve such effectiveness promptly
following such one hundred eighty (180) day period;

          (c)  The Company shall not be required to effect a registration
pursuant to this Section 8 more than once in any twelve (12) month period;

          (d)  The Company shall not be required to maintain and keep any such
registration on Form S-3 effective for a period exceeding one hundred eighty
(180) days from the effective date thereof. The Company shall give notice to all
Holders and all holders of registration rights under any other agreement of the
Company granting Form S-3 or similar demand registration rights of the receipt
of a request for registration pursuant to this Section 8 and shall provide a
reasonable opportunity for all such other holders to participate in the
registration. Subject to the foregoing, the Company will use its best efforts to
effect promptly the registration of all shares of Registrable Securities on Form
S-3 to the extent requested by the Holder or Holders thereof for purposes of
disposition. In the event the Underwriter, in the case of an underwritten
offering, determines that market factors require a limitation on the number of
shares to be underwritten, then shares shall be excluded from such registration
and underwriting pursuant to the method described in Section 6(b); and

          (e)  The value of the aggregate shares of Registrable Securities to be
registered on Form S-3 for each such right of registration shall be at least
$500,000.

     9.   Registration Procedures.  In the case of each registration effected by
          -----------------------
the Company pursuant to this Agreement, the Company will keep each Holder
advised in writing as to the initiation of such registration and as to the
completion thereof. At its expense, the Company will:

          (a)  Keep such registration effective for a period of ninety (90) days
(except as set forth in Section 8(d)) or until the Holder or Holders have
completed the distribution described in the registration statement relating
thereto, whichever first occurs; and

          (b)  Furnish such number of prospectuses and other documents incident
thereto as a Holder from time to time may reasonably request; and

          (c)  In connection with any underwritten offering pursuant to a
registration statement filed pursuant to Section 5 or 8 hereof, the Company will
enter into any underwriting

                                       8
<PAGE>

agreement reasonably necessary to effect the offer and sale of Common Stock,
provided such underwriting agreement contains customary underwriting provisions,
and provided further that if the underwriter so requests the underwriting
agreement will contain customary indemnification and contribution provisions,
and provided further that the Underwriter is reasonably acceptable to the
Company.

     10.  Indemnification.
          ---------------

          (a)  The Company will indemnify each Holder, each of its officers,
directors and partners, and each person controlling such Holder, if Registrable
Securities held by such Holder are included in the securities with respect to
which registration, qualification or compliance has been effected pursuant to
this Agreement, and each underwriter, if any, and each person who controls any
underwriter, against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any prospectus, offering
circular or other document (including any related registration statement,
notification or the like) incident to any such registration, qualification or
compliance, or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading,
or any violation by the Company of the Securities Act including any rule or
regulation thereunder applicable to the Company relating to action or inaction
required of the Company in connection with any such registration, qualification
or compliance, and will reimburse each such Holder, each of its officers,
directors and partners, and each person controlling such Holder, each such
underwriter and each person who controls any such underwriter, for any legal and
any other expenses reasonably incurred in connection with investigating and
defending any such claim, loss, damage, liability or action, provided that the
Company will not be liable in any such case to the extent that any such claim,
loss, damage, liability or expense arises out of or is based on any untrue
statement (or alleged untrue statement) or omission (or alleged omission) based
upon written information furnished to the Company by such Holder or underwriter
and stated to be specifically for use therein.

          (b)  Each Holder will, if Registrable Securities or other securities
held by such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, indemnify the
Company, each of its directors, officers and agents and each underwriter, if
any, of the Company's securities covered by such a registration statement, each
person who controls the Company or such underwriter within the meaning of the
Securities Act and the rules and regulations thereunder, each other such Holder
and each of their officers, directors and partners, and each person controlling
such Holder, against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances in
which they were made, not misleading, and will reimburse the Company and such
Holders, directors, officers, agents, partners, persons, underwriters or control
persons for any legal or any other expenses reasonably incurred in connection
with investigating or defending any such claim, loss, damage, liability or
action, in each case to the extent, but only to the extent, that such

                                       9
<PAGE>

untrue statement (or alleged untrue statement) or omission (or alleged omission)
is made in such registration statement, prospectus, offering circular or other
document in reliance upon and in conformity with written information furnished
to the Company by such Holder and stated to be specifically for use therein;
provided, however, that the obligations of such Holders hereunder shall be
limited to an amount equal to the net proceeds to each such Holder of securities
sold as contemplated herein.

          (c)  Each party entitled to indemnification under this Section 10 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or any litigation resulting
therefrom, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Agreement. An indemnified party
shall have the right to retain its own 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. No Indemnifying
Party in the defense of any such claim or litigation shall, except with the
consent of each Indemnified Party, consent to entry of any judgment or enter
into any settlement which does not include as an unconditional term thereof the
giving by the claimant or plaintiff to such Indemnified Party of a release from
all liability in respect to such claim or litigation. Each Indemnified Party
shall furnish such information regarding itself or the claim in question as an
Indemnifying Party may reasonably request in writing and as shall be reasonably
required in connection with defense of such claim and litigation resulting
therefrom.

          (d)  If the indemnification provided for in this Section 10 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the extent permitted by applicable law contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability 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 any untrue or alleged untrue statement of a material fact or
the omission to state a material fact that resulted in such loss, claim, damage
or liability, as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by a court of law 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;
provided, that in no event shall any contribution by a Holder thereunder exceed
the proceeds from the offering received by such Holder.

                                       10
<PAGE>

          (e)  The obligations of the Company and Holders under this Section 10
shall survive completion of any offering of Registrable Securities in a
registration statement and the termination of this agreement.

     11.  Information by Holder.  Each Holder holding securities included in any
          ---------------------
registration shall furnish to the Company such information regarding such Holder
as the Company may reasonably request in writing and as shall be reasonably
required in connection with any registration, qualification or compliance
referred to in this Agreement.

     12.  Limitations on Registration of Issues of Securities.  From and
          ---------------------------------------------------
after the date of this Agreement, the Company shall not enter into any agreement
with any holder or prospective holder of any securities of the Company giving
such holder or prospective holder the right to require the Company to initiate
any registration of any securities of the Company, provided that this Section 12
shall not limit the right of the Company to enter any agreements with any holder
or prospective holder of any securities of the Company giving such holder or
prospective holder the right to require the Company, upon any registration of
any of its securities, to include, among the securities which the Company is
then registering, securities owned by such holder. Any right given by the
Company to any holder or prospective holder of the Company's securities in
connection with the registration of securities shall be conditioned such that it
shall be consistent with the provisions of this Agreement and with the rights of
the Holders provided in this Agreement.

     13.  Rule 144 Reporting.  With a view to making available the benefits of
          ------------------
certain rules and regulations of the Commission which may permit the sale of the
Restricted Securities to the public without registration, the Company agrees to:

          (a)  Make and keep public information available as those terms are
understood and defined in Rule 144 under the Securities Act, at all times from
and after ninety (90) days following the effective date of the first
registration under the Securities Act filed by the Company for an offering of
its securities to the general public;

          (b)  Use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act at any time after it has become subject to
such reporting requirements;

          (c)  So long as a Shareholder owns any Restricted Securities, furnish
to the Shareholder forthwith upon request a written statement by the Company as
to its compliance with the reporting requirements of Rule 144 (at any time from
and after ninety (90) days following the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents so filed as a Shareholder may reasonably request in availing itself of
any rule or regulation of the Commission allowing a Shareholder to sell any such
securities without registration.

     14.  No-Action Letter or Opinion of Counsel in Lieu of Registration.
          --------------------------------------------------------------
Notwithstanding anything in this Agreement to the contrary, if at any time after
the date of the Company's initial

                                       11
<PAGE>

public offering of its securities under the Securities Act the Company shall
have obtained from the Commission a "no-action" letter in which the Commission
has indicated that it will take no action if, without registration under the
Securities Act, any Holder disposes of Registrable Securities covered by any
request for registration made under this Agreement in the manner in which such
Holder proposes to dispose of the Registrable Securities included in such
request, or if in the opinion of counsel for the Company concurred in by counsel
for such Holder no registration under the Securities Act is required in
connection with such disposition, the Registrable Securities included in such
request shall not be eligible for registration under this Agreement; provided,
however, with respect to any Holder who may deemed to be an "affiliate," as that
term is defined under Rule 144, if, notwithstanding the opinion of such counsel,
the Holder is unable to dispose of all of the Registrable Securities included in
his request in the manner in which such Holder so proposes without registration,
the Registrable Securities included in such request shall be eligible for
registration under this Agreement.

     15.  Transfer or Assignment of Registration Rights.  The rights to cause
          ---------------------------------------------
the Company to register a Shareholder's securities granted to such Shareholder
by the Company under Sections 5, 6 and 8 hereof may be transferred or assigned
by the Shareholder to a transferee or assignee of at least 100,000 shares of the
Restricted Securities; provided, however, that a Shareholder may transfer or
assign such rights to a partner or shareholder of Shareholder or to a successor
trust or successor trustee without restriction as to minimum shareholding. The
Company shall be given written notice by Shareholder at the time of said
transfer or assignment, stating the name and address of said transferee or
assignee and identifying the securities with respect to which such registration
rights are being transferred or assigned, and provided further that the
transferee or assignee of such rights is not deemed by the Board of Directors of
the Company, in its reasonable judgment, to be a competitor of the Company; and
provided further that the transferee or assignee of such rights assumes the
obligations of a Shareholder under this Agreement.

     16.  "Market Stand-off" Agreement.  Each Shareholder agrees, if requested
          ----------------------------
by the Company and an underwriter of Common Stock (or other securities) of the
Company, not to sell or otherwise transfer or dispose of any Common Stock (or
other securities) of the Company held by Shareholder during a period of time
determined by the Company and its underwriters (not to exceed 180 days)
following the effective date of the Company's initial public offering of its
capital stock, provided that all officers, directors and employees of the
Company holding stock or stock options of at least one (1%) percent of the
Company's outstanding stock prior to the initial public offering of the Company
enter into similar agreements; provided, further, that with respect to the
Series C Holders and Series D Holders, the prohibition against the sale,
transfer or other dispostions of any Common Stock (or other securities) of the
Company held by them pursuant to this Section 16 shall not prohibit (i) the sale
of any shares of Common Stock purchased by such Series C Holder or Series D
Holder pursuant to a directed share program or otherwise in the Company's
initial public offering, or (ii) the sale, in the open market, of any shares of
Common Stock by such Series C Holder or Series D Holder provided that such
shares are purchased in the open market after the completion of the Company's
initial public offering.

                                       12
<PAGE>

          Such agreement shall be in writing in a form satisfactory to the
Company and such underwriter. The Company may impose stop-transfer instructions
with respect to the Shares (or securities) subject to the foregoing restriction
until the end of said period.

     17.  Governing Law.  This Agreement and the legal relations between the
          -------------
parties arising hereunder shall be governed by and interpreted in accordance
with the laws of the State of California. The parties hereto agree to submit to
the jurisdiction of the federal and state courts of the State of California with
respect to the breach or interpretation of this Agreement or the enforcement of
any and all rights, duties, liabilities, obligations, powers, and other
relations between the parties arising under this Agreement.

     18.  Entire Agreement.  This Agreement constitutes the full and entire
          ----------------
understanding and agreement between the parties regarding rights to
registration. Except as otherwise expressly provided herein, the provisions
hereof shall inure to the benefit of, and be binding upon, the successors,
assigns, heirs, executors and administrators of the parties hereto.

     19.  Notices, Etc. All notices and other communications required or
          -------------
permitted hereunder shall be in writing and shall be mailed by first-class mail,
postage prepaid, or otherwise delivered by hand or by messenger, addressed (a)
if to a Shareholder, at the address or addresses set forth on Exhibit A, Exhibit
                                                              ---------  -------
B, Exhibit C, Exhibit D or Exhibit E attached hereto, or at such other address

                  -------------------------------------------



     THIS SERIES A PREFERRED STOCK PURCHASE AGREEMENT ("Agreement") is made as
of the 8th day of July 1994 by and between Inventa Corporation, a California

of Investors attached hereto as Exhibit A (the "Investors").

     THE PARTIES HEREBY AGREE AS FOLLOWS:

     1.   Purchase and Sale of Series A Preferred Stock
          ---------------------------------------------

          1.1.   Sale and Issuance of Common Stock.
                 ---------------------------------

                 (a)   The Company shall adopt and file with the Secretary of
State of California on or before the Closing (as defined below) the Amended and
Restated Articles of Incorporation in the form attached hereto as Exhibit B.

                 (b)   Subject to the terms and conditions of this Agreement,
the Investors agree to purchase at the Closing and the Company agrees to sell
and issue to the Investors at the Closing that number of shares of the Company's
Series A Preferred Stock (the "Stock") for the aggregate purchase price set
forth opposite each Investor's name on Exhibit A attached hereto, at a purchase
price of $1.00 per share.

          1.2    Closing   Date; Delivery.  The purchase and sale of the Stock
                 ------------------------
shall take place at the offices of Wilson, Sonsini, Goodrich & Rosati, 650 Page
Mill Road, Palo Alto, California, at 9:00 a.m., on July 8, 1994, or at such
other time and place as the Company and the Investors mutually agree upon,
orally or in writing (which time and place are designated as the "Closing"). At
the Closing, the Company shall deliver to each Investor a certificate
representing the Stock which such Investor is purchasing against delivery to the
Company by such Investor of a check made payable to the Company or wire transfer
of the aggregate purchase price therefor.

          1.3.   Warrants.  At the Closing, the Company shall issue to each
                 --------
Investor a Warrant ("Warrant") in the form attached hereto as Exhibit D. Each
Warrant shall be exercisable at the Investor's option for that number of shares
of Series A Preferred Stock of the Company equal to one-fourth of the number of

of $1.00 per share. The Warrants shall expire at the earlier of (i) December 31,
1999, (ii) a registered public offering of the Company's securities, or (iii) a
merger, reorganization or sale of all or substantially all of the Company's
assets.

                 ---------------------------------------------
a corporation duly organized, validly existing and in good standing under the
laws of the State of California and has all requisite corporate power and
authority to carry on its business as now conducted and as proposed to be

standing in each jurisdiction in which the failure so to qualify would have a
material adverse effect on its business or properties.

          2.2    Capitalization.

                 (a)   The authorized capital of the Company will consist,

shares are issued and outstanding. The Company has reserved 675,000 shares of
its Common Stock for issuance pursuant to its 1993 Stock Option Plan. Except as
set forth in the Schedule of Exceptions attached as Exhibit C hereto, there are
no outstanding options, warrants, rights (including conversion or preemptive
rights) or agreements, orally or in writing, for the purchase or acquisition
from the Company of any shares of its capital stock.

          2.3    Subsidiaries.  The Company does not presently own or control,
                 ------------
directly or indirectly, any interest in any other corporation, association, or
other business entity.

          2.4    Authorization.  All corporate action on the part of the
                 -------------
Company, its officers, directors and shareholders 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 prior to the Closing, and

                 (a)   The Stock that is being issued to the Investors
hereunder, when issued, sold and delivered in accordance with the terms hereof
for the consideration expressed herein, will be duly and validly issued, fully
paid and nonassessable. Based in part upon the representations of the Investors
in this Agreement, the Stock will be issued in compliance with all applicable
federal and state securities laws.

                                      -2-

state securities laws.

                 (c)   The Warrants to be issued to the Investors in

                 ---------------------
authorization of, or registration, qualification, designation, declaration or
filing with, any federal, state or local governmental authority on the part of
the Company is required in connection with the consummation of the transactions
contemplated by this Agreement, except for (a) the filing pursuant to Section
25102(f) of the California Corporate Securities Law of 1968, as amended, and the
rules thereunder, which filing will be effected in accordance with such section,
and (b) compliance with the Blue Sky Laws of the various states in which the
Investors may reside, which compliance will be effected in accordance with such
laws. The Company currently holds all licenses, permits, franchises,
registrations and qualifications which may be required to conduct its business,
and all such licenses, permits, franchises, registrations and qualifications are
valid and in full force and effect.

          2.7    Litigation.  There is no action, suit, proceeding or
                 ----------
investigation pending or currently threatened against the Company that questions
the validity of this Agreement or the right of the Company to enter into it, or
to consummate the transactions contemplated hereby, or that might result, either
individually or in the aggregate, in any material adverse changes in the assets,
condition, affairs or prospects of the Company, financially or otherwise, or any
change in the current equity ownership of the Company, nor is the Company aware
that there is any basis for the foregoing. The foregoing includes, without
limitation, actions pending or threatened (or any basis therefor known to the
Company) involving the prior employment of any of the Company's employees, their
use in connection with the Company's business of any information or techniques
allegedly proprietary to any of their former employers, or their obligations
under any agreements with prior employers. The Company is not a party or subject
to the provisions of any order, writ, injunction, judgment or decree of any

nor any other statements or certificates made or delivered in connection

be subject to the terms hereof to the same extent as if they were the Investor
hereunder.

each Holder written notice thereof (which shall include a list of the
jurisdictions in which the Company intends to attempt to qualify such securities
under the applicable Blue Sky or other state securities laws) and (ii) include

Blue Sky laws or other compliance), and in any underwriting involved therein,

Company by any Holder within 30 days after delivery of such written notice from
the Company.

Company gives notice is for a Registered public offering involving an
underwriting, the Company shall so advise the Holders as a part of the written
notice given pursuant to Section 7.4(a) or 7.5. In such event, the right of any
Holder to Registration shall be conditioned upon such underwriting and the
inclusion of such Holder's Registrable Securities in such underwriting to the
extent provided in this Section 7.6. All Holders proposing to distribute their
securities through such underwriting shall (together with the Company and any
other holders distributing their securities through such underwriting) enter
into an underwriting agreement with the Underwriter's Representative for such
offering. The Holders shall have no right to participate in the selection of the
underwriters for an offering pursuant to this Section 7.6.

                 (b)   Marketing Limitation.  In the event the Underwriter's
                       --------------------
Representative advises the Holders seeking Registration of Registrable
Securities in writing that market factors (including, without limitation, the
aggregate number of shares of Common Stock requested to be Registered, the
general condition of the market, and the status of the persons proposing to sell
securities pursuant to the Registration) require a limitation of the number of
shares to be underwritten, the Underwriter's Representative may limit, but not
to less than 10% of the total number of shares proposed to be registered under
this Section 7.6 (unless such Registration is the Company's initial public
offering, in which case no limitation on reduction shall be imposed), the number
of shares of Registrable Securities to be included in such Registration and
underwriting; provided however, that any Registrable Securities so excluded
shall retain any and all Registration rights set forth in this Section.

                 (c)   Allocation of Shares.  In the event that the
                       --------------------
Underwriter's Representative limits the number of shares to be included in a
Registration pursuant to Section 7.4(b), the number

                                      -13-
<PAGE>

of shares to be included in such Registration shall be allocated in the
following manner:

                       (i)  in the case of a Registration pursuant to
Section 7.5, shares held by persons who are not legally entitled to include
shares in such Registration shall first be excluded from such Registration and
underwriting to the extent required by such limitation.  If a limitation of the
number of shares is still required after such exclusion, shares of Registrable
Securities shall next be excluded from such Registration and underwriting to the
extent required by such limitation, all prior to any limitation on the shares to
be Registered by the Company.

                       The number of shares that may be included in the
Registration and underwriting by selling shareholders shall be allocated among
all Holders thereof and other holders of securities other than Registrable
Securities requesting and legally entitled to include shares in such
Registration, in proportion, as nearly as practicable, to the respective amounts
of securities (including Registrable Securities) which such Holders and such
other holders would otherwise be entitled to include in such Registration. No
Registrable Securities or other securities excluded from the underwriting by
reason of this Section 7.6(c) shall be included in the Registration Statement.

                 (d)   Withdrawal.  If any Holder disapproves of the terms of
                       ----------
any such underwriting, he may elect to withdraw therefrom by written notice to
the Company and the underwriter delivered at least seven days prior to the
effective date of the Registration Statement. Any Registrable Securities or
other securities excluded or withdrawn from such underwriting shall be withdrawn
from such Registration.

          7.7    Blue Sky.  In the event of any Registration of Registrable
                 --------
Securities pursuant to Section 7.4 or 7.5, the Company will exercise its best
efforts to register and/or qualify the securities covered by the Registration
Statement under such other securities or Blue Sky laws of such jurisdictions
(not exceeding 20 unless otherwise agreed to by the Company) as shall be
reasonably appropriate for the distribution of such securities; provided,
however, that (i) the Company shall not be required to qualify to do business or
to file a general consent to service of process in any such states or
jurisdictions, and (ii) notwithstanding anything in this Agreement to the
contrary, in the event any jurisdiction in which the securities shall be
qualified imposes a non-waivable requirement that expenses incurred in
connection with the qualification of the securities be borne by selling
shareholders, such expenses shall be payable pro rata by selling shareholders.

          7.8    Expenses of Registration.  Registration expenses incurred  with
                 ------------------------
no more than two Registrations pursuant to Section 7.4, and all Registration
Expenses incurred in connection with Registrations pursuant to Section 7.5,
shall be borne by the Company, excluding underwriting discounts and commissions.
All Selling Expenses shall be borne by the holders of the securities Registered
pro rata on the basis of the number of shares registered.

          7.9    Registration Procedures.  The Company will keep each Holder
                 -----------------------
whose Registrable Securities are included in any Registration pursuant to this
Agreement advised as to the initiation and completion of such Registration. The
Company shall: (a) keep such Registration effective for a period of 120 days or
until the Holder or Holders have completed the distribution described in the
Registration Statement relating thereto, whichever first occurs; and (b) furnish
such number of prospectuses (including preliminary prospectuses) and other
documents as a Holder from time to time reasonably may request.

          7.10   Information Furnished by Holder.  It shall be a condition
                 -------------------------------
precedent of the Company's obligations under this Section that each Holder of
Registrable Securities included in any Registration furnish to the Company such
information regarding such Holder and the distribution proposed by such Holder
or Holders as the Company may reasonably request.

          7.11   Indemnification.
                 ---------------

                 (a)   Company's Indemnification of Holders.  To the extent
                       ------------------------------------
permitted by law, the Company shall indemnify each Holder, each of its officers,
directors and constituent partners, legal counsel for the Holders, and each
person controlling such Holder, with respect to which Registration,
qualification or compliance of Registrable Securities has been effected pursuant
to this Agreement against all claims, losses, damages or liabilities (or actions
in respect thereof) to the extent such claims, losses, damages or liabilities
arise out of or are based upon any untrue statement (or alleged untrue
statement) of a material fact contained in any prospectus or other document
(including any related Registration Statement) incident to any such
Registration, qualification or compliance, or are based on any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, or any violation by
the Company of any rule or regulation promulgated under the Securities Act
applicable to the Company and relating to action or inaction required of the
Company in connection with any such Registration, qualification or compliance;
and the Company will reimburse each such Holder, such directors, officers,
partners or law firm, each such underwriter and each person who controls any
such Holder or underwriter, for any legal and any other expenses

                                      -15-
<PAGE>

reasonably incurred in connection with investigating or defending any such
claim, loss, damage, liability or action; provided, however, that the indemnity
contained in this Section 7.11 shall not apply to amounts paid in settlement of
any such claim, loss, damage, liability or action if settlement is effected
without the consent of the Company (which consent shall not unreasonably be
withheld); and provided, further, that the Company will not be liable in any
such case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based upon any untrue statement or omission based upon
written information furnished to the Company by such Holder, officer, director,
partner, counsel or controlling person and stated to be specifically for use in
connection with the Registration and offering of securities of the Company.

          (b)    Holder's Indemnification of Company.  To the extent permitted
                 -----------------------------------
by law, each Holder shall, if Registrable Securities held by such Holder are
included in the securities as to which such Registration, qualification or
compliance is being effected pursuant to this Agreement, indemnify the Company,
each of its directors and officers, each legal counsel and independent
accountant of the Company, each underwriter, if any, of the Company's securities
covered by such a Registration Statement, each person who controls the Company
or such underwriter within the meaning of the Securities Act, and each other
such Holder, each of its officers, directors and constituent partners and each
person controlling such other Holder, against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based upon any
untrue statement (or alleged untrue statement) of a material fact contained in
any such Registration Statement, prospectus, offering circular or other
document, or any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or any violation by such Holder of any rule or regulation
promulgated under the Securities Act applicable to such Holder and relating to
action or inaction required of such Holder in connection with any such
Registration, qualification or compliance; and will reimburse the Company, such
Holders, such directors, officers, partners, persons, law and accounting firms,
underwriters and control persons for any legal and any other expenses reasonably
incurred in connection with investigating or defending any such claim, loss,
damage, liability or action, in each case to the extent, but only to the extent,
that such untrue statement (or alleged untrue statement) or omission (or alleged
omission) is made in such Registration Statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by such Holder, or an officer, director, constituent
partner, counsel or controlling persons of such Holder, and stated to be
specifically for use in connection with the Registration and offering of
securities of the Company.

                    (c)   Indemnification Procedure. Promptly after receipt by
                          -------------------------
an indemnified party under this Section 7.11 of notice of the commencement of
any action, such indemnified party will, if a claim in respect thereof is to be
made against an indemnifying party under this Section 7.11 notify the
indemnifying party in writing of the commencement thereof and generally
summarize such action. The indemnifying party shall have the right to
participate in and to assume the defense of such claim; provided, however, that
the indemnifying party shall be entitled to select counsel for the defense of
such claim with the approval of any parties entitled to indemnification, which
approval shall not be unreasonably withheld; provided further, however, that if
either party reasonably determines that there may be a conflict between the
position of the Company and the Holders in conducting the defense of such
action, suit or proceeding by reason of recognized claims for indemnity under
this Section 7.11 then counsel for such party shall be entitled to conduct the
defense to the extent reasonably determined by such counsel to be necessary to
protect the interest of such party. The failure to notify an indemnifying party
promptly of the commencement of any such action, if prejudicial to the ability
of the indemnifying party to defend such action, shall relieve such indemnifying
party, to the extent so prejudiced, of any liability to the indemnified party
under this Section 7.11 but the omission so to notify the indemnifying party
will not relieve such party of any liability that such party may have to any
indemnified party otherwise other than under this Section 7.11.

          7.12      Rule 144 Reporting. With a view to making available the
                    ------------------
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of the restricted securities to the public without
registration, after such time as a public market exists for the Common Stock of
the Company, the Company agrees to use its best efforts to:

                    (a)    Make and keep public information available, as those
terms are understood and defined in Rule 144 under the Securities Act, at all
times after the effective date that the Company becomes subject to the reporting
requirements of the Securities Act or the Securities Exchange Act of 1934, as
amended.

                    (b)    Use its best efforts to file with the Commission in a
timely manner all reports and other documents required of the Company under the
Securities Act and the Securities Exchange Act of 1934, as amended (at any time
after it has become subject to such reporting requirements);

                    (c)    So long as a Purchaser owns any restricted securities
to furnish to the Purchaser forthwith upon request a written statement by the
Company as to its compliance with the reporting requirements of said Rule 144
(at any time after 90 days after the effective date of the first registration
statement filed

                                      -17-
<PAGE>

by the Company for an offering of its securities to the general public), and of
the Securities Act and the Securities Exchange Act of 1934 (at any time after it
has become subject to such reporting requirements), a copy of the most recent
annual or quarterly report of the Company, and such other reports and documents
of the Company and other information in the possession of or reasonably
obtainable by the Company as a Purchaser may reasonably request in availing
itself of any rule or regulation of the Commission allowing a Purchaser to sell
any such securities without registration.

          7.13      Transfer of Registration Rights. The rights to cause the
                    -------------------------------
Company to register securities granted Holders under Sections 7.4 and 7.5 may be
assigned to a transferee or assignee reasonably acceptable to the Company in
connection with any transfer or assignment of Registrable Securities by a Holder
provided that (i) such transfer may otherwise be effected in accordance with
applicable securities laws, and (ii) such assignee or transferee acquires either
(A) at least 50,000 shares of Registrable Securities or (B) all Registrable
Securities held by such transferring or assigning Holder. Notwithstanding the
foregoing, the rights to cause the Company to register securities may be
assigned to any constituent partner of a Holder, without compliance with item
(ii) above, provided written notice thereof is promptly given to the Company.

     8.   Right of First Refusal.
          ----------------------

          8.1  Grant of Right.  Except as set forth in Section 8.5, the

Company hereby grants to each Investor who continues to hold Stock the right of
first refusal to purchase all or any part of such Investor's Pro Rata Share (as
hereinafter defined) of the New Securities (as defined in Section 8.2) which the
Company may, from time to time, propose to sell and issue.  The Investors may
purchase said New Securities on the same terms and at the same price at which
the Company proposes to sell the New Securities.  The "Pro Rata Share" of each
Investor, for purposes of this right of first refusal, is the ratio of the total
number of shares of Common Stock held by such Investor, including (i) any shares
of Common Stock into which shares of Preferred Stock held by such Investor are
convertible, and (ii) any shares deliverable upon the exercise of options of
other rights to purchase Common Stock held by such Investor, to the total number
of shares of Common Stock outstanding immediately prior to the issuance of the
New Securities (including (i) any shares of Common Stock into which outstanding
shares of Preferred Stock are convertible and (ii) any shares deliverable upon
the exercise of options of other rights to purchase Common Stock held by such
Investor).

          8.2  New Securities.   "New Securities" shall mean any capital
               --------------

warrants to purchase said capital stock, and

                                      -18-
<PAGE>

securities of any type whatsoever that are, or may become, convertible into said
capital stock; provided, however, that "New Securities" does not include (i) the
               --------  -------
shares of Stock purchased pursuant to this Agreement or other securities issued
or issuable upon conversion of the Stock ("Conversion Shares"), (ii) securities
offered pursuant to a registration statement filed under the Securities Act of
1933 ("Securities Act"), (iii) securities issued pursuant to the acquisition of
another corporation by the Company by merger, purchase of substantially all of
the assets or other reorganization, (iv) shares offered pursuant to lease
financing transactions or bank or lending institution financing transactions,

employees or consultants of the Company (for the primary purpose of soliciting
or retaining their employment or services) pursuant to any employee or
consultant stock offering, plan or arrangement approved by the Board of
Directors.

          8.3  Notice.  In the event the Company proposes to undertake
               ------
an issuance of New Securities, it shall give to the Investors written notice
(the "Notice") of its intention, describing the type of New Securities, number
of shares, the price, the terms upon which the Company proposes to issue the
same, and notice to the effect that each Investor must respond to such Notice
within thirty (30) days after the date thereof.  The Investors shall have thirty
(30) days from the date of such Notice to purchase any or all of the New
Securities for the price and upon the terms specified in the Notice by giving
written notice to the Company and stating therein the quantity of New Securities
to be purchased and forwarding payment for such New Securities to the Company if
immediate payment is required by such terms, or in any event no later than
forty-five (45) days after the date of the Notice.

          8.4  Sale after Notice.  In the event any Investor fails to
               -----------------
exercise in full the right of first refusal within said thirty (30) day period,
the Company shall have ninety (90) days thereafter to sell or enter into an
agreement (pursuant to which the sale of New Securities covered thereby shall be
closed, if at all, within thirty (30) days from the date of said agreement) to
sell the New Securities respecting which such Investor's rights were not
exercised, at a price and upon general terms no more favorable to the Investors
thereof than specified in the Notice.  In the event the Company has not sold the
New Securities within said ninety (90) day period (or sold and issued New
Securities in accordance with the foregoing within thirty (30) days from the
date of said agreement), the Company shall not thereafter issue or sell any New
Securities without first offering such securities to the Investors in the manner
provided above.

          8.5  Expiration.  The right of first refusal granted under this
               ----------
Section 8 shall expire upon the earlier of:

                       RESTATED ARTICLES OF INCORPORATION

                                       OF

                               INVENTA CORPORATION

                                       I.

      The name of this corporation is Inventa Corporation.

                                       II.

      The purpose of this corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of
California other than the banking business, the trust company business or the
practice of a profession permitted to be incorporated by the California
Corporations Code.

                                       III.

      This corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock." The total number
of shares which the corporation is authorized to issue is 10,500,000 shares, of
which 10,000,000 shares shall be Common Stock with a par value of $0.001 per
share and of which 500,000 shares shall be Preferred Stock, all of which are
designated Series A Preferred Stock with a par value of $0.001 per share.

                                       IV.

      The rights, preferences, privileges and restrictions granted to or imposed
upon the Common Stock and Preferred Stock are as follows:

      1. Dividend Provisions. The holders of shares of Series A Preferred Stock
shall be entitled to receive dividends, out of any assets legally available
therefor, prior and in preference to any declaration or payment of any dividend
(payable other than in Common Stock or other securities and rights convertible
into or entitling the holder thereof to receive, directly or indirectly,
additional shares of Common Stock of this corporation) on the Common Stock of
this corporation, at the rate of $0.06 per share


                                      -3-
<PAGE>

per annum or, if greater (as determined on a per annum basis and on an as
converted basis for the Series A Preferred Stock), an amount equal to that paid
on the Common Stock. Such dividends shall be payable when, as, and if declared
by the Board of Directors, and shall not be cumulative, and no right shall
accrue to holders of Common Stock or Preferred Stock by reason of the fact that
dividends on said shares are not declared in any prior period.

      2. Liquidation Preference.

            (a) Preferred Preference. In the event of any liquidation,
dissolution or winding up of this corporation, either voluntary or involuntary,
the holders of Series A Preferred Stock shall be entitled to receive, prior and
in preference to any distribution of any of the assets of this corporation to
the holders of Common Stock by reason of their ownership thereof, an amount per
share equal to $1.00 for each outstanding share of Series A Preferred Stock plus
an amount equal to any declared but unpaid dividends on such share up to the
date fixed for distribution. If upon the occurrence of such event, the assets
and funds thus distributed among the holders of the Series A Preferred Stock
shall be insufficient to permit the payment to such holders of the full
aforesaid preferential amounts, then the entire assets and funds of this
corporation legally available for distribution shall be distributed ratably
among the holders of the Series A Preferred Stock in proportion to the amount of
such Series A Preferred Stock owned by each such holder.

            (b) After payment has been made to the holders of the Series A
Preferred Stock of the full amount to which they shall be entitled as set forth
in paragraph 2(a) above, the holders of the Common Stock shall then be entitled
to receive the amount of $.15 per share for each share of Common Stock then held
by them, adjusted for any combinations, consolidations, subdivisions, or stock
dividends with respect to such shares and, in addition, an amount equal to all
declared but unpaid dividends on the Common Stock. If the assets and funds thus
distributed among the holders of the Common Stock shall be insufficient to
permit the payment to such holders of the full aforesaid amount, then the entire
assets and funds of the Corporation legally available for distribution, after
payment has been made to the holders of the Series A Preferred Stock of the full
amount to which they shall be entitled as set forth in paragraph 2(a) above,
shall be distributed among the holders of the Common Stock in proportion to the
full amount each such holder is otherwise entitled to receive.

            (c) After payment has been made to the holders of the Series A
Preferred Stock and the Common Stock of the full amount to which they shall be
entitled as set forth in paragraphs 2(a) and 2(b) above, the holders of the
Series A Preferred Stock and Common Stock shall be entitled to receive ratably
on a per-share basis all


                                      -4-
<PAGE>

the remaining assets based upon the number of shares of Common Stock into which
each share of Preferred is then convertible; provided, however, that the holders
of Series A Preferred Stock shall not be entitled to receive pursuant to this
paragraph (c) (including amounts received pursuant to paragraphs (a) and (b)
above) more than a total of $2.00 per share of Series A Preferred Stock then
held by them, adjusted for any combinations, consolidations, or stock splits
with respect to such shares. If the assets and funds thus distributed among the
holders of each series of Preferred and Common Stock shall be insufficient to
permit the payment of the full aforesaid preferential amounts as provided in
this paragraph (c), the remaining funds and assets of the Corporation available
for distribution shall be distributed among the holders of each series of
Preferred and Common Stock in proportion to the amount each such holder is
otherwise entitled to receive pursuant to this paragraph (c).

            (d) After payment has been made to the holders of the Series A
Preferred Stock and the Common Stock of the full amounts to which they shall be
entitled as set forth in paragraphs 2(a), 2(b) and 2(c) above, the holders of
the Common Stock shall be entitled to receive ratably on a per-share basis all
the remaining assets.

            (e) Mergers. For purposes of this Section 2, a merger or
consolidation of the Corporation with or into any other corporation or
corporations, the merger of any other corporation or corporations into the
Corporation, in which the shareholders of the Corporation receive distributions
in cash or securities of another corporation or corporations as a result of such
consolidation or merger, a reorganization where the shareholders of the Company
immediately prior to the transaction possess less than 50% of the voting power
of the surviving entity (or its parent) immediately after the transaction, or a
sale of all or substantially all of the assets of the corporation, shall be
treated as a liquidation, dissolution or winding up of the Corporation; provided
that the holders of Preferred Stock and Common Stock shall each be paid in cash
or in the securities received or in a combination thereof (which combination
shall be in the same proportions as the consideration received in the
transaction). Any securities to be delivered to the holders of the Series A
Preferred Stock and Common Stock upon merger, reorganization or sale of
substantially all the assets of the corporation shall be valued as follows:

                  (i) if actively traded over-the-counter, the value shall be
deemed to be the average of the closing bid prices over


                                      -5-
<PAGE>

the 30-day period ending three (3) business days prior to the closing; and

                  (ii) if there is no active public market, the value shall be
the fair market value thereof as mutually determined by the corporation and the
holders of not less than a majority of the outstanding shares of Series A
Preferred Stock, provided that if the corporation and the holders of a majority
of the outstanding shares of Series A Preferred Stock are unable to reach
agreement, then by independent appraisal by an investment banker hired and paid
by the corporation, but acceptable to the holders of a majority of the
outstanding shares of Series A Preferred Stock.

            (f) As authorized by Section 402.5(c) of the California Corporations
Code, the provisions of Sections 502 and 503 of the California Corporations Code
shall not apply with respect to repurchase by the Corporation of shares of
Common Stock issued to or held by employees or consultants of the Corporation or
its subsidiaries upon termination of their employment or services pursuant to
agreement providing for the right of said repurchase.

      3. Conversion. The holders of the Series A Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

            (a) Right to Convert. Each share of Series A Preferred Stock shall
be convertible into share(s) of Common Stock without the payment of any
additional consideration by the holder thereof and, at the option of the holder
thereof, at any time after the date of issuance of such share, at the office of
the corporation or any transfer agent for the Series A Preferred Stock. Each
share of Series A Preferred Stock shall be convertible into the number of fully
paid and nonassessable shares of Common Stock which results from dividing the
Conversion Price (as hereinafter defined) per share in effect for the Series A
Preferred Stock at the time of conversion into the per share Conversion Value
(as hereinafter defined) of such series. The initial Conversion Price per share
of Series A Preferred Stock shall be $1.00, and the Conversion Value per share
of the Series A Preferred Stock shall be $1.00. The initial Conversion Price of
Series A Preferred Stock shall be subject to adjustment from time to time as
provided below. The number of shares of Common Stock into which a share of
Series A Preferred Stock is convertible is hereinafter referred to as the
"Conversion Rate" of such series.

            (b) Automatic Conversion. Each share of Series A Preferred Stock
shall automatically be converted into shares of Common Stock at its then
effective Conversion Rate immediately upon the closing of a firm commitment
underwritten public offering pursuant to an effective registration statement
under the Securities Act of 1933, as amended, covering the offer and sale of
Common Stock in which (a) the public offering price equals or exceeds $3.00 per


                                      -6-
<PAGE>

share (adjusted to reflect subsequent stock dividends, stock splits or
recapitalization) and (b) the aggregate proceeds raised equals or exceeds
$5,000,000.

            (c) Mechanics of Conversion. Before any holder of Series A Preferred
Stock shall be entitled to convert the same into shares of Common Stock, he
shall surrender the certificate or certificates therefor, duly endorsed, at the
office of the corporation or of any transfer agent for the Series A Preferred
Stock and shall give written notice to the corporation at such office that he
elects to convert the same (except that no such written notice of election to
convert shall be necessary in the event of an automatic conversion pursuant to
Section 3(b) hereof). The corporation shall, as soon as practicable thereafter,
issue and deliver at such office to such holder of Series A Preferred Stock a
certificate or certificates for the number of shares of Common Stock to which
such holder shall be entitled as aforesaid. Such conversion shall be deemed to
have been made immediately prior to the close of business on the date of such
surrender of the shares of Series A Preferred Stock to be converted (except that
in the case of an automatic conversion pursuant to Section 3(b) hereof such
conversion shall be deemed to have been made immediately prior to the closing of
the offering referred to in Section 3(b)) and the person or persons entitled to
receive the shares of Common Stock issuable upon such conversion shall be
treated for all purposes as the record holder or holders of such shares of
Common Stock on such date.

            (d) Fractional Shares. In lieu of any fractional shares to which the
holder of Series A Preferred Stock would otherwise be entitled, the corporation
shall pay cash equal to such fraction multiplied by the fair market value of one
share of such series of Preferred Stock as determined by the board of directors
of the corporation. Whether or not fractional shares are issuable upon such
conversion shall be determined on the basis of the total number of shares of
Series A Preferred Stock of each holder to be converted at such time into Common
Stock and the number of shares of Common Stock issuable upon such aggregate
conversion.

            (e) Adjustment of Conversion Price. The Conversion Price of Series A
Preferred Stock shall be subject to adjustment from time to time as follows:

                  (i) If the corporation shall issue any Common Stock other than
"Excluded Stock", as defined below, for a consideration per share less than the
Conversion Price in effect immediately prior to the issuance of such Common
Stock (excluding Stock dividends, subdivisions, split-ups, combinations,
dividends or recapitalizations which are covered by Section 3(e)(iii), (iv), (v)
and (vi)), the Conversion Price in effect immediately after each such issuance
shall forthwith (except as provided in this Section 3(e)) be adjusted to a price
equal to the quotient obtained by dividing:


                                      -7-
<PAGE>

                        (1) an amount equal to the sum of

                              (x) the total number of shares of Common Stock
outstanding (including any shares of Common Stock issuable upon conversion of
the Series A Preferred Stock, or deemed to have been issued pursuant to
subdivision (3) of this clause (i) and to clause (ii) below) immediately prior
to such issuance multiplied by the Conversion Price in effect immediately prior
to such issuance, plus

                              (y) the consideration received by the corporation
upon such issuance, by

                        (2) the total number of shares of Common Stock
outstanding (including any shares of Common Stock issuable upon conversion of
the Series A Preferred Stock or deemed to have been issued pursuant to
subdivision (3) of this clause (i) and to clause (ii) below) immediately prior
to such issuance plus the additional shares of Common Stock issued in such
issuance (but not including any additional shares of Common Stock deemed to be
issued as a result of any adjustment in the Conversion Price resulting from such
issuance).

                        For purposes of any adjustment of the Conversion Price
pursuant to this clause (i), the following provisions shall be applicable:

                              (1) In the case of the issuance of Common Stock
for cash, the consideration shall be deemed to be the amount of cash paid
therefor after deducting any discounts or commissions paid or incurred by the
corporation in connection with the issuance and sale thereof.

                              (2) In the case of the issuance of Common Stock
for a consideration in whole or in part other than cash, the consideration other
than cash shall be deemed to be the fair market value thereof as determined by
the board of directors of the corporation, in accordance with generally accepted
accounting treatment; provided, however, that if, at the time of such
determination, the corporation's Common Stock is traded in the over-the-counter
market or on a national or regional securities exchange, such fair market value
as determined by the board of directors of the corporation shall not exceed the
aggregate "Current Market Price" (as defined below) of the shares of Common
Stock being issued.

                              (3) In the case of the issuance of (i) options to
purchase or rights to subscribe for Common Stock (other than Excluded Stock),
(ii) securities by their terms convertible into or exchangeable for Common Stock
(other than Excluded


                                      -8-
<PAGE>

Stock), or (iii) options to purchase or rights to subscribe for such convertible
or exchangeable securities:

                                    (A) the aggregate maximum number of shares
of Common Stock deliverable upon exercise of such options to purchase or rights
to subscribe for Common Stock shall be deemed to have been issued at the time
such options or rights were issued and for a consideration equal to the
consideration (determined in the manner provided in subdivisions (1) and (2)
above), if any, received by the corporation upon the issuance of such options or
rights plus the minimum purchase price provided in such options or rights for
the Common Stock covered thereby;

                                    (B) the aggregate maximum number of shares
of Common Stock deliverable upon conversion of or in exchange for any such
convertible or exchangeable securities or upon the exercise of options to
purchase or rights to subscribe for such convertible or exchangeable securities
and subsequent conversion or exchange thereof, shall be deemed to have been
issued at the time such securities were issued or such options or rights were
issued and for a consideration equal to the consideration received by the
corporation for any such securities and related options or rights (excluding any
cash received on account of accrued interest or accrued dividends), plus the
minimum additional consideration, if any, to be received by the corporation upon
the conversion or exchange of such securities or the exercise of any related
options or rights (the consideration in each case to be determined in the manner
provided in subdivisions (1) and (2) above);

                                    (C) on any change in the number of shares of
Common Stock deliverable upon exercise of any such options or rights or
conversion of or exchange for such convertible or exchangeable securities, or on
any change in the minimum purchase price of such options, rights or securities,
other than a change resulting from the antidilution provisions of such options,
rights or securities, the Conversion Price shall forthwith be readjusted to such
Conversion Price as would have obtained had the adjustment made upon (x) the
issuance of such options, rights or securities not exercised, converted or
exchanged prior to such change, as the case may be, been made upon the basis of
such change or (y) the options or rights related to such securities not
converted or exchanged prior to such change, as the case may be, been made upon
the basis of such change; and

                                    (D) on the expiration of any such options or
rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price shall forthwith be readjusted to such
Conversion Price as would have obtained had the adjustment made upon the
issuance of such options, rights, convertible or exchangeable securities or
options or rights


                                      -9-
<PAGE>

related to such convertible or exchangeable securities, as the case may be, been
made upon the basis of the issuance of only the number of shares of Common Stock
actually issued upon the exercise of such options or rights, upon the conversion
or exchange of such convertible or exchangeable securities or upon the exercise
of the options or rights related to such convertible or exchangeable securities,
as the case may be.

                  (ii) "Excluded Stock" shall mean:

                        (1) all shares of Common Stock issued and outstanding on
the date this document is filed with the California Secretary of State and all
shares issuable upon exercise of options or warrants outstanding on the date
this document is filed with the California Secretary of State;

                        (2) all shares of Series A Preferred Stock and the
Common Stock into which the shares of Series A Preferred Stock are convertible;
and

                        (3) all shares of Common Stock, warrants or options to
purchase Common Stock or other securities issued to officers, directors,
consultants or employees of the corporation pursuant to any plan or arrangement
approved by the board of directors of the corporation.

                        All outstanding shares of Excluded Stock (including any
shares issuable upon conversion of the Preferred Stock) shall be deemed to be
outstanding for all purposes of the computations of Section 3(e)(i) above.

                  (iii) If the number of shares of Common Stock outstanding at
any time after the date hereof is increased by a stock dividend payable in
shares of Common Stock or by a subdivision or split-up of shares of Common
Stock, then, on the date such payment is made or such change is effective, the
Conversion Price of Series A Preferred Stock shall be appropriately decreased so
that the number of shares of Common Stock issuable on conversion of any shares
of such series of Series A Preferred Stock shall be increased in proportion to
such increase of outstanding shares.

                  (iv) If the number of shares of Common Stock outstanding at
any time after the date hereof is decreased by a combination of the outstanding
shares of Common Stock, then, on the effective date of such combination, the
Conversion Price of Series A Preferred Stock shall be appropriately increased so
that the number of shares of Common Stock issuable on conversion of any shares
of a series of Series A Preferred Stock shall be decreased in proportion to such
decrease in outstanding shares.

<PAGE>

                  (v) In case the corporation shall declare a cash dividend upon
its Common Stock payable otherwise than out of retained earnings or shall
distribute to holders of its Common Stock shares of this capital stock (other
than Common Stock), stock or other securities of other persons, evidences of
indebtedness issued by the corporation or other persons, assets (excluding cash
dividends) or options or rights (excluding options to purchase and rights to
subscribe for Common Stock or other securities of the corporation convertible
into or exchangeable for Common Stock), then, in each such case, the holders of
shares of Series A Preferred Stock shall, concurrent with the distribution to
holders of Common Stock, receive a like distribution based upon the number of
shares of Common Stock into which Series A Preferred Stock is convertible.

            (vi) In case, at any time after the date hereof, of any capital
reorganization, or any reclassification of the stock of the corporation (other
than as a result of a stock dividend or subdivision, split-up or combination of
shares), or the consolidation or merger of the corporation with or into another
person (other than a consolidation or merger in which the corporation is the
continuing entity and which does not result in any change in the Common Stock),
or of the sale or other disposition of all or substantially all the properties
and assets of the corporation, the shares of Series A Preferred Stock shall,
after such reorganization, reclassification, consolidation, merger, sale or
other disposition, be convertible into the kind and number of shares of stock or
other securities or property of the corporation or otherwise to which such
holder would have been entitled if immediately prior to such reorganization,
reclassification, consolidation, merger, sale or other disposition he had
converted his shares of Series A Preferred Stock into Common Stock. The
provisions of this clause (vi) shall similarly apply to successive
reorganizations, reclassifications, consolidations, mergers, sales or other
dispositions.

                  (vii) All calculations under this Section 3 shall be made to
the nearest cent or to the nearest one hundredth (1/100) of a share, as the case
may be.

                  (viii) For the purpose of any computation pursuant to this
Section 3(e), the "Current Market Price" at any date of one share of Common
Stock, shall be deemed to be the average of the highest reported bid and the
lowest reported offer prices on the preceding business day as furnished by the
National Quotation Bureau, Incorporated (or equivalent recognized source of
quotations); provided, however, that if the Common Stock is not traded in such
manner that the quotations referred to in this clause (viii) are available for
the period required hereunder, Current Market Price shall be determined in good
faith by the board of directors of the corporation, but if challenged by the
holders of more than 50%


                                      -11-
<PAGE>

of the outstanding Series A Preferred Stock, then as determined by an
independent appraiser selected by the board of directors of the corporation, the
cost of such appraisal to be borne by the challenging parties.

            (f) Minimal Adjustments. No adjustment in the Conversion Price need
be made if such adjustment would result in a change in the Conversion Price of
less than $0.01. Any adjustment of less than $0.01 which is not made shall be
carried forward and shall be made at the time of and together with any
subsequent adjustment which, on a cumulative basis, amounts to an adjustment of
$0.01 or more in the Conversion Price.

            (g) No Impairment. With the consent of the majority of the
outstanding shares of Preferred Stock, the corporation will not through any
reorganization, recapitalization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms to be observed
or performed hereunder by the corporation, but will at all times in good faith
assist in the carrying out of all the provisions of this Section 3 and in the
taking of all such action as may be necessary or appropriate in order to protect
the Conversion Rights of the holders of Series A Preferred Stock against
impairment.

            (h) Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Conversion Rate pursuant to this Section 3,
the corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Preferred Stock a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The corporation shall, upon written request at any time
of any holder of Series A Preferred Stock, furnish or cause to be furnished to
such holder a like certificate setting forth (i) such adjustments and
readjustments, (ii) the Conversion Rate of such series at the time in effect,
and (iii) the number of shares of Common Stock and the amount, if any, of other
property which at the time would be received upon the conversions of such
holder's shares of Series A Preferred Stock.

            (i) Notices of Record Date. In the event of any taking by the
corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property or to receive any other right, the corporation
shall mail to each holder of Series A Preferred Stock at least ten (10) days
prior to such record date, a notice specifying the date on which any such record
is to be taken for the purpose of such


                                      -12-
<PAGE>

dividend or distribution or right, and the amount and character of such
dividend, distribution or right.

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

            (k) Notices. Any notice required by the provisions of this Section 3
to be given to the holder of shares of Series A Preferred Stock shall be deemed
given if deposited in the United States mail, postage prepaid, and addressed to
each holder of record at his address appearing on the books of the corporation.

            (l) Reissuance of Converted Shares. No shares of Series A Preferred
Stock which have been converted into Common Stock after the original issuance
thereof shall ever again be reissued and all such shares so converted shall upon
such conversion cease to be a part of the authorized shares of the corporation.

      4. Voting Rights. The holder of each share of Series A Preferred Stock
shall be entitled to the number of votes equal to the number of shares of Common
Stock into which each share of Series A Preferred Stock could be converted on
the record date for the vote or consent of shareholders written consent and,
except as otherwise required by law, shall have voting rights and powers equal
to the voting rights and powers of the Common Stock. The holder of each share of
Series A Preferred Stock shall be entitled to notice of any shareholders'
meeting in accordance with the bylaws of the corporation and shall vote with
holders of the Common Stock upon the election of directors and upon any other
matter submitted to a vote of shareholders, except those matters required by law
to be submitted to a class vote. Fractional votes shall not, however, be
permitted and any fractional voting rights resulting from the above formula
(after aggregating all shares of Common Stock into which shares of Series A
Preferred Stock held by each holder could be converted) shall be rounded to the
nearest whole number (with one-half rounded upward to one).

      5. Protective Provisions. In addition to any other class vote that may be
required by law, so long as any shares of


                                      -13-
<PAGE>

Preferred Stock are outstanding, this corporation shall not without first
obtaining the approval (by vote or written consent, as provided by law) of the
holders of at least a majority of the then outstanding shares of Preferred
Stock:

            (a) sell, convey or otherwise dispose of all or substantially all of
its property or business, or merge into or effect a reorganization with any
other corporation (other than a wholly owned subsidiary corporation) in which
the shareholders of this corporation immediately prior to the transaction
possess less than 50% of the voting power of the surviving entity (or its
parent) immediately after the transaction;

            (b) change the rights, preferences, privileges or restrictions of
the Preferred Stock;

            (c) increase or decrease the aggregate number of authorized shares
of Preferred Stock, other than as provided in either subdivision (b) of Section
405 or subdivision (c) of Section 902 of the California Corporations Code;

            (d) create a new class or series of shares having rights,
preferences or privileges or increase the number of authorized shares of any
class or shares having rights, preferences or privileges prior to any
outstanding class or series;

            (e) repurchase from any shareholder any of the corporation's Common
Stock other than repurchases at cost from employees, consultants, lessors or
suppliers upon termination of employment, consulting, lessor-lessee, or
supplier-purchaser relationship, respectively; or

            (f) increase the authorized number of directors of the corporation
above five (5).

      6. Repurchase of Shares. In connection with repurchases by this
corporation of its Common Stock, pursuant to its agreements with certain of the
holders thereof, Sections 502 and 503 of the California General Corporation Law
shall not apply in whole or in part with respect to such repurchases.

                                       V.

      1. Limitation of Directors' Liability. The liability of the directors of
this corporation for monetary damages shall be eliminated to the fullest extent
permissible under California law.

      2. Indemnification of Corporate Agents. This corporation is authorized to

purposes of this provision the


                                      -14-
<PAGE>

term "agent" has the meaning set forth in Section 317 of the California
Corporations Code.

      3. Repeal or Modification. Any repeal or modification of the foregoing
provisions of this Article V shall not adversely affect any right of

                             SCHEDULE OF EXCEPTIONS

      This Schedule of Exceptions, dated as of the Closing Date, is made and
given pursuant to Section 2 of the Inventa Corporation Series A Preferred Stock
Purchase Agreement dated July 8, 1994 (the "Agreement").

      The section numbers in this Schedule of Exceptions correspond to the
section numbers in the Agreement; however, any information disclosed herein
under any section number shall be deemed to be disclosed and incorporated into
any other section number under the Agreement where such disclosure would be
appropriate. Unless the context otherwise requires, all capitalized terms shall
have the same meanings assigned to them in the Agreement.

      2.1 Organization and Standing; Certificate and Bylaws.

      The Company is not qualified to do business in any state other than
California, its jurisdiction of incorporation.

      2.2 Capitalization.

      The Company has granted a warrant to purchase 7,502 shares of common stock
of the Company (after taking into account the Company's October 22, 1993
4.5-for-1 stock split). The warrant, with a post-split exercise price of $1.33
per share, is subject to antidilution adjustment.

      2.3 Subsidiaries.

      The Company has a wholly-owned subsidiary in Malaysia called ICG Systems
SDN.BHD. The Company also has a subsidiary in India called Inventa Software
India Pvt. Ltd. ("Inventa India"). Of the outstanding shares of capital stock of
Inventa India, the Company owns approximately 22%, the Company's President Ashok
Santhanam owns approximately 30.5%, and the balance is owned by Indian
investors. Subsequent to the Closing, the Company will purchase Mr. Santhanam's
interest in Inventa India at par value, equal to approximately $32,000.00.

      2.7 Litigation.

      The California Employment Development Department has entered a judgment of
approximately $15,000 against the Company for the period ending December 31,
1992 based on the Company's payment of certain expenses (the "Disputed
Payments") for work done for the Company in the United States by employees of
Inventa India. The Company has appealed the judgment. Should the Company's
appeal be unsuccessful, the Company expects that the judgment against the
Company for disputed payments through December 31, 1993 will not exceed $25,000.
<PAGE>

      The Internal Revenue Service is currently conducting an examination of the
Company with respect to federal tax returns filed by the Company for tax years
1990, 1991 and 1992 which included the Disputed Payments. No determination has
yet been made by the IRS.

      The Company is contemplating filing a claim in Malaysia for trademark
infringement with respect to the name "Inventa" and also is contemplating
seeking a name change for or the dissolution of the Malaysian company Inventa
Software (M) SDN.BHD.

      2.9 Compliance with Other Instruments.

      (a) See Section 2.7 above regarding a judgment by the California

                 WARRANT TO PURCHASE SERIES A PREFERRED STOCK OF
                               INVENTA CORPORATION

                                                                    July 8, 1994

      THIS CERTIFIES that, for value received, and subject to all of the
provisions and upon the terms and conditions hereinafter set forth, 1~ (the
"Holder"), is entitled to subscribe for and purchase 2~ shares of Series A
Preferred Stock (the "Shares") of Inventa Corporation, a California corporation,
with its principal office at 2620 Augustine Drive, Suite 225, Santa Clara,
California 95054 (the "Corporation"). This Warrant is being originally delivered
pursuant to that certain Series A Preferred Stock Purchase Agreement between the
Corporation and the Holder (the "Agreement").

      SECTION 1. Exercise of Warrant. The rights represented by this Warrant may
be exercised in whole or in part at any time during the period commencing at the
date of issuance of this Warrant (the "Issuance Date") and ending at the earlier
of (i) December 31, 1999, (ii) the date of the Corporation's initial public
offering of its securities at a price per share of at least $3.00 and for a
total offering price of at least $5,000,000, or (iii) the date of closing of the
sale of all or substantially all of the assets or the outstanding capital stock
of the Corporation, or the merger of the Corporation if the shareholders of the
Corporation shall own less than fifty percent of the outstanding voting
securities of the surviving corporation immediately following such merger (the
"Exercise Period"), by delivery of the following to the Corporation at its
address set forth above (or at such other address as it may designate by notice
in writing to the Holder):

            (a) An executed Notice of Exercise in the form attached hereto;

            (b) Payment of the exercise price of $1.00 per Share (the "Exercise
Price") in cash or by check; and

            (c) This Warrant.
<PAGE>

      In the event of exercise of the rights represented by this Warrant, a
certificate or certificates for the Shares issuable pursuant to such exercise
(the "Exercise Shares") registered in the name of the Holder or persons
affiliated with the Holder, if the Holder so designates, shall be issued and
delivered to the Holder within a reasonable time after such exercise but in any
event within thirty days.

      The person in whose name any certificate or certificates for Exercise
Shares are to be issued upon exercise of this Warrant shall be deemed to have
become the holder of record of such shares on the date on which this Warrant was
surrendered and payment of the Exercise Price was made, irrespective of the date
of delivery of such certificate or certificates, except that, if the date of
such surrender and payment is a date when the stock transfer books of the
Corporation are closed, such person shall be deemed to have become the holder of
such shares at the close of business on the next succeeding date on which the
stock transfer books are open.

      SECTION 2. Covenants of the Corporation.

            2.1 Covenants as to Exercise Shares. The Corporation agrees that all
Exercise Shares that may be issued upon the exercise of the rights represented
by this Warrant will, upon issuance, be validly issued and outstanding, fully
paid and nonassessable, and free from all taxes, liens and charges with respect
to the issuance thereof (other than taxes in respect of any transfer occurring
contemporaneously with such issue). The Corporation further agrees that the
Corporation will at all times beginning on the Issuance Date and thereafter
during the Exercise Period, have authorized and reserved, free from preemptive
rights, a sufficient number of shares of its stock to provide for the exercise
of the rights represented by this Warrant. If at any time during the Exercise
Period the number of authorized but unissued shares of stock shall not be
sufficient to permit exercise of this Warrant, the Corporation will take such
corporate action as may, in the opinion of its counsel, be necessary to increase
its authorized but unissued shares of stock to such number of shares as shall be
sufficient for such purposes.

            2.2 Notices of Record Date. In the event of any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend which is the same as cash dividends paid in
previous quarters) or other distribution, the Corporation shall mail to the
Holder, at least ten (10) days prior to the date specified herein, a notice
specifying the date on which any such record is to be taken for the purpose of
such dividend or distribution.

      SECTION 3. Adjustment Provisions.

            3.1 Adjustment of Number of Exercise Shares. The number of Exercise
Shares shall be subject to adjustment from time to time as follows:

                  (a) If, at any time during the Exercise Period, the number of
outstanding shares of stock of the Corporation of the class and series covered
by this Warrant is increased by a subdivision or split-up of such outstanding
shares, then, concurrently with the effectiveness of such subdivision or
split-up, the number of Exercise Shares shall be proportionately increased and
the Exercise Price proportionately decreased.

                  (b) If, at any time during the Exercise Period, the number of
outstanding shares of stock of the Corporation of the class and series covered
by this Warrant is decreased by a combination of such outstanding shares, then,
concurrently with the effectiveness of such combination, the number of Exercise
Shares shall be proportionately decreased and the Exercise Price proportionately
increased.

            3.2 Certificate as to Adjustments. Upon the occurrence of any
adjustment or readjustment of the number of securities issuable upon exercise of
this Warrant in accordance with paragraph 3.1, the Corporation shall compute
such adjustment or readjustment in accordance with the terms hereof and furnish
to the Holder a written statement setting forth each adjustment or readjustment
and the facts upon which such adjustment or readjustment is based. The form of
this Warrant need not be changed because of any adjustment in the number of
securities subject to this Warrant.

            3.3 Fractional Shares. No fractional shares shall be issued upon the
exercise of this Warrant as a consequence of any adjustment pursuant to
paragraph 3.1 or otherwise. All Exercise Shares (including fractions) issuable
upon exercise of this Warrant may be aggregated for purposes of determining
whether such exercise would otherwise result in the issuance of any fractional
share. If, after aggregation, such exercise would otherwise result in the
issuance of a fractional share, the Corporation shall, in lieu of such issuance
of any such fractional share, pay the Holder a sum in cash equal to the product
resulting from multiplying the then current fair market value of an Exercise
Share by such fraction.

      SECTION 4. No Shareholder Rights. This Warrant in and of itself shall not
entitle the Holder to any voting rights or other rights as a shareholder of the
Corporation.

      SECTION 5. Transfer of Warrant. Subject to applicable laws and to the
restriction on transfer set forth on the first page of this Warrant, this
Warrant and all rights hereunder are


                                      -3-
<PAGE>

transferable, by the Holder in person or by duly authorized attorney, upon
delivery of this Warrant and the form of assignment attached hereto to any
transferee designated by Holder, so long as such transferee executes an
investment letter in form and substance satisfactory to the Corporation. Upon
any such transfer, the transferee shall thereafter be deemed the Holder for
purposes of this Warrant.

      SECTION 6. Loss, Theft, Destruction or Mutilation of Warrant. Upon receipt
by the Corporation of evidence reasonably satisfactory to it of the loss, theft,
destruction or mutilation of this Warrant, and in case of loss, theft or
destruction, of indemnity or security reasonably satisfactory to it, and upon
reimbursement to the Corporation of all reasonable expenses incidental thereto,
and upon surrender and cancellation of this Warrant if mutilated, the
Corporation will make and deliver a new Warrant of like tenor and dated as of
such cancellation, in lieu of this Warrant.

      SECTION 7. Notices, etc. All notices and other communications required or
permitted hereunder shall be in writing and shall be sent by telex, telegram,
express mail or other form of rapid communications, if possible, and if not then
such notice or communication shall be mailed by first-class mail, postage
prepaid, addressed to the Holder and the Corporation at their addresses set
forth herein, or at such other address as one party may furnish to the other in
writing. Notice shall be deemed effective on the date dispatched if by personal
delivery, telex or telegram, two days after mailing if by express mail, or three
days after mailing if by first-class mail.

      SECTION 8. Acceptance. Receipt of this Warrant by the Holder shall
constitute acceptance of and agreement to all of the terms and conditions
contained herein.

      IN WITNESS WHEREOF, the Corporation has caused this Warrant to be executed
by its duly authorized officer as of the 8th day of July, 1994.

                               INVENTA CORPORATION
                    EMPLOYMENT, CONFIDENTIAL INFORMATION AND
                         INVENTION ASSIGNMENT AGREEMENT

      As a condition of my employment with Inventa Corporation, its
subsidiaries, affiliates, successors or assigns (the "Company"), and in
consideration of my employment with the Company and my receipt of the
compensation now and hereafter paid to me by the Company, I agree to the
following:

      1. At-Will Employment. I understand and acknowledge that my employment
with the Company is for an unspecified duration and constitutes "at-will"
employment. I acknowledge that this employment relationship may be terminated at
any time, with or without good cause or for any or no cause, at the option
either of the Company or myself, with or without notice.

      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 of the Company's 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 configuration information, marketing, finances
or other business information disclosed to me by the Company either directly or
indirectly in writing, orally or by drawings or observation of parts or
equipment. I further understand that Confidential Information does not include
any of the foregoing items which has become publicly known and 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.
<PAGE>

            (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) Inventions Retained and Licensed. I have attached hereto, as
Exhibit A, a list describing 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 the 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.

            (b) 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"), except as
provided in Section 3(f) below. 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.

            (c) 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


                                      -2-
<PAGE>

is required to be in the United States by a contract between the Company and the
United States or any of its agencies.

            (d) 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.

            (e) 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, 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.

            (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 which qualifies fully under the provisions of California Labor
Code Section 2870 (attached hereto as Exhibit B). I will advise the Company
promptly in writing of any inventions that I believe meet the criteria in
California Labor Code Section 2870 and not otherwise disclosed on Exhibit A.

      4. Conflicting Employment. I agree that, during the term of my employment
with the Company, I will not engage in any other


                                      -3-
<PAGE>

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.

      5. Returning the 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 Certification" attached hereto as Exhibit
C.

      6. 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 about my rights and obligations under this Agreement.

      7. Solicitation of Employees. I agree that for a period of twelve (12)
months immediately following the termination of my relationship with the Company
for any reason, whether with or without cause, I shall not either directly or
indirectly solicit, induce, recruit or encourage any of the Company's employees
to leave their employment, or take away such employees, or attempt to solicit,
induce, recruit, encourage or take away employees of the Company, either for
myself or for any other person or entity.

      8. Conflict of Interest Guidelines. I agree to diligently adhere to the
Conflict of Interest Guidelines attached as Exhibit D hereto.

      9. Representations. I agree to execute any proper oath or verify any
proper document required to carry out the terms of this Agreement. I represent
that my performance of all the terms of this Agreement will not breach any
agreement to keep in confidence proprietary 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.

      10. Arbitration and Equitable Relief.

            (a) Arbitration. Except as provided in Section 10(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


                                      -4-
<PAGE>

San Francisco 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 of such Sections, 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.

      11. General Provisions.

            (a) Governing Law; Consent to Personal Jurisdiction. This Agreement
will be governed by the laws of the State of California. I hereby expressly
consent to the personal jurisdiction of the state and federal courts located in
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 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.

            (c) 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.

            (d) 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.

      "(a) Any provision in an employment agreement which provides that an

                         CONFLICT OF INTEREST GUIDELINES

      It is the policy of 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 personnel actions affecting reward or
punishment of employees or applicants where there is a family relationship or is
or appears to be a personal or social involvement.

      5. Initiating or approving any form of personal or social harassment of
employees.

      6. 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.

      7. Borrowing from or lending to employees, customers or suppliers.

      8. Acquiring real estate of interest to the Company.

      9. Improperly using or disclosing to the Company any proprietary
information or trade secrets of any former or
<PAGE>

concurrent employer or other person or entity with whom obligations of
confidentiality exist.

      10. Unlawfully discussing prices, costs, customers, sales or markets with
competing companies or their employees.

      11. Making any unlawful agreement with distributors with respect to
prices.

      12. Improperly using or authorizing the use of any inventions which are
the subject of patent claims of any other person or entity.

      13. 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.

business by the employees of the Company, nor the conduct of the Company's

state statute, rule or regulation applicable to the Company. The execution,
delivery and performance of this Agreement and the consummation of the
transactions contemplated hereby will not result in any such violation or be in
conflict with or constitute, with or without the passage of time and giving of
notice, either a default under any such provision, instrument, judgment, order,
writ, decree, contract, rule, or statute, or of the Company's Restated Articles
of Incorporation or Bylaws, or an event which results in the creation of any
lien, charge or encumbrance upon any assets of the Company.

                 AMENDED AND RESTATED ARTICLES OF INCORPORATION

                                       OF

                               INVENTA CORPORATION

                                       I.

      The name of this corporation is Inventa Corporation (the "Corporation").

                                       I.

      The purpose of this Corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of
California other than the banking business, the trust company business or the
practice of a profession permitted to be incorporated by the California
Corporations Code.

                                       I.

      This Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock." The total number
of shares which the Corporation is authorized to issue is 23,560,000 shares, of
which 20,000,000 shares shall be Common Stock with a par value of $0.001 per
share and of which 3,560,000 shares shall be Preferred Stock, 1,000,000 of which
are designated Series A Preferred Stock with a par value of $0.001 per share and
2,560,000 of which are designated Series B Preferred Stock with a par value of
$0.001 per share.

      Upon the filing of these Amended and Restated Articles of Incorporation,
each outstanding share of Common Stock and and each outstanding share of
Preferred Stock shall be split up and reconstituted as two shares of Common
Stock and Preferred Stock, respectively. The numbers in these Amended and
Restated Articles of Incorporation have been adjusted to reflect the foregoing
stock split, and consequently no further adjustment, including any adjustment
with respect to the Conversion Prices of any series of Preferred Stock pursuant
to Section IV.3(e)(iii), shall be made with respect to the foregoing stock
split.
<PAGE>

                                       I.

      The rights, preferences, privileges and restrictions granted to or imposed
upon the Common Stock and Preferred Stock are as follows:

      A. Dividend Provisions. The holders of shares of Series A Preferred Stock
("Series A Preferred") and Series B Preferred Stock ("Series B Preferred") shall
be entitled to receive dividends, out of any assets legally available therefor,
prior and in preference to any declaration or payment of any dividend (payable
other than in Common Stock or other securities and rights convertible into or
entitling the holder thereof to receive, directly or indirectly, additional
shares of Common Stock of this Corporation) on the Common Stock of this
Corporation, at the rate of $0.03 per annum per share of Series A Preferred (as
adjusted for any stock dividends, combinations, splits, recapitalizations and
the like with respect to such shares) and $0.075 per annum per share of Series B
Preferred (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares) or, if greater (as
determined on a per annum basis and on an as converted basis for the Series A
Preferred and Series B Preferred), an amount equal to that paid on the Common
Stock. Such dividends shall be payable when, as, and if declared by the Board of
Directors, and shall not be cumulative, and no right shall accrue to holders of
Common Stock or Preferred Stock by reason of the fact that dividends on said
shares are not declared in any prior period.

      A. Liquidation Preference.

            1. Preferred Preference. In the event of any liquidation,
dissolution or winding up of this Corporation, either voluntary or involuntary,
the holders of Series A Preferred and Series B Preferred shall be entitled to
receive, prior and in preference to any distribution of any of the assets of
this Corporation to the holders of Common Stock by reason of their ownership
thereof, an amount per share equal to $.50 for each outstanding share of Series
A Preferred (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares) and $1.25 for each
outstanding share of Series B Preferred (as adjusted for any stock dividends,
combinations, splits, recapitalizations and the like with respect to such
shares), plus an amount equal to any declared but unpaid dividends on each such
share up to the date fixed for distribution. If upon the occurrence of such
event, the assets and funds thus distributed among the holders of Preferred
Stock shall be insufficient to permit the payment to such holders of the full
aforesaid preferential amounts, then the entire assets and funds of this
Corporation legally available for distribution shall be distributed, in
proportion to the preferential amount each such holder is otherwise entitled to
receive pursuant to this paragraph (a), among the holders of the Preferred Stock
in proportion to the amount of such Series A Preferred and Series B Preferred
owned by each such holder.

            1. After payment has been made to the holders of the Preferred Stock
of the full amount to which they shall be entitled as set forth in paragraph
2(a) above, the holders of the Common Stock shall then be entitled to receive
the amount of $0.20 per share for each share of Common Stock then held by them,
adjusted for any combinations, consolidations, subdivisions, or stock dividends
with respect to such shares and, in addition, an amount equal to all declared
but unpaid dividends on the Common Stock. If the assets and funds thus
distributed among the holders


                                      -2-
<PAGE>

of the Common Stock shall be insufficient to permit the payment to such holders
of the full aforesaid amount, then the entire assets and funds of the
Corporation legally available for distribution, after payment has been made to
the holders of the Preferred Stock of the full amount to which they shall be
entitled as set forth in paragraph 2(a) above, shall be distributed among the
holders of the Common Stock in proportion to the full amount each such holder is
otherwise entitled to receive.

            1. After payment has been made to the holders of the Preferred Stock
and the Common Stock of the full amount to which they shall be entitled as set
forth in paragraphs 2(a) and 2(b) above, the holders of the Preferred Stock and
Common Stock shall be entitled to receive ratably on a per-share basis all the
remaining assets based upon the number of shares of Common Stock into which each
share of Preferred is then convertible; provided, however, that the holders of
Preferred Stock shall not be entitled to receive pursuant to this paragraph (c)
(including amounts received pursuant to paragraph (a) above) more than a total
of $1.00 per share of Series A Preferred and $2.50 per share of Series B
Preferred then held by them, adjusted for any combinations, consolidations, or
stock splits with respect to such shares. If the assets and funds thus
distributed among the holders of each series of Preferred and Common Stock shall
be insufficient to permit the payment of the full aforesaid preferential amounts
as provided in this paragraph (c), the remaining funds and assets of the
Corporation available for distribution shall be distributed among the holders of
each series of Preferred and Common Stock in proportion to the amount each such
holder is otherwise entitled to receive pursuant to this paragraph (c).

            1. After payment has been made to the holders of the Preferred Stock
and the Common Stock of the full amounts to which they shall be entitled as set
forth in paragraphs 2(a), 2(b) and 2(c) above, the holders of the Common Stock
shall be entitled to receive ratably on a per-share basis all the remaining
assets.

            1. Mergers. For purposes of this Section 2, a merger or
consolidation of the Corporation with or into any other corporation or
corporations, the merger of any other corporation or corporations into the
Corporation, in which the shareholders of the Corporation receive distributions
in cash or securities of another corporation or corporations as a result of such
consolidation or merger, a reorganization where the shareholders of the
Corporation immediately prior to the transaction possess less than 50% of the
voting power of the surviving entity (or its parent) immediately after the
transaction, or a sale of all or substantially all of the assets of the
Corporation, shall be treated as a liquidation, dissolution or winding up of the
Corporation; provided that the holders of the Preferred Stock and the Common
Stock shall each be paid in cash or in the securities received or in a
combination thereof (which combination shall be in the same proportions as the
consideration received in the transaction). Any securities to be delivered to
the holders of the Preferred Stock and Common Stock upon merger, reorganization
or sale of substantially all the assets of the Corporation shall be valued as
follows:

                  a) if traded on a securities exchange, the value shall be
deemed to be the average of the closing prices of the securities on such
exchange over the 30-day period ending three (3) business days prior to the
closing;


                                      -3-
<PAGE>

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

                  a) if there is no active public market, the value shall be the
fair market value thereof as mutually determined by the Corporation and the
holders of not less than a majority of the outstanding shares of the Preferred
Stock, provided that if the Corporation and the holders of a majority of the
outstanding shares of the Preferred Stock are unable to reach agreement, then by
independent appraisal by an investment banker hired and paid by the Corporation,
but acceptable to the holders of a majority of the outstanding shares of
Preferred Stock.

            1. As authorized by Section 402.5(c) of the California Corporations
Code, the provisions of Sections 502 and 503 of the California Corporations Code
shall not apply with respect to repurchase by the Corporation of shares of
Common Stock issued to or held by employees or consultants of the Corporation or
its subsidiaries upon termination of their employment or services pursuant to
agreement providing for the right of said repurchase.

      A. Conversion. The holders of the Series A Preferred and Series B
Preferred shall have conversion rights as follows (the "Conversion Rights"):

            1. Right to Convert. Each share of Series A Preferred and Series B
Preferred shall be convertible into share(s) of Common Stock without the payment
of any additional consideration by the holder thereof and, at the option of the
holder thereof, at any time after the date of issuance of such share, at the
office of the Corporation or any transfer agent for the Series A Preferred and
Series B Preferred. Each share of Series A Preferred and Series B Preferred
shall be convertible into the number of fully paid and nonassessable shares of
Common Stock which results from dividing the Conversion Price (as hereinafter
defined) per share in effect for the Series A Preferred and Series B Preferred
at the time of conversion into the per share Conversion Value (as hereinafter
defined) of such series. The initial Conversion Price per share of Series A
Preferred shall be $.50, and the Conversion Value per share of the Series A
Preferred shall be $.50. The initial Conversion Price per share of the Series B
Preferred shall be $1.25, and the Conversion Value per share of the Series B
Preferred shall be $1.25. The initial Conversion Price of Series A Preferred and
Series B Preferred shall be subject to adjustment from time to time as provided
below. The number of shares of Common Stock into which a share of Series A
Preferred and Series B Preferred is convertible is hereinafter referred to as
the "Conversion Rate" of such series.

            1. Automatic Conversion. Each share of Series A Preferred and Series
B Preferred shall automatically be converted into shares of Common Stock at the
applicable effective Conversion Rate immediately upon the closing of a firm
commitment underwritten public offering pursuant to an effective registration
statement under the Securities Act of 1933, as amended, covering the offer and
sale of Common Stock in which (a) the public offering price equals or exceeds
$1.75 per share (adjusted to reflect subsequent stock dividends, stock splits or
recapitalization) for the Series A Preferred and $4.00 per share (adjusted to
reflect subsequent stock dividends, stock splits or recapitalization) for the
Series B Preferred and (b) the aggregate proceeds raised equals or exceeds
$5,000,000 for the Series A Preferred and $10,000,000 for the Series B
Preferred.


                                      -4-
<PAGE>

            1. Mechanics of Conversion. Before any holder of the Preferred Stock
shall be entitled to convert the same into shares of Common Stock, he shall
surrender the certificate or certificates therefor, duly endorsed, at the office
of the Corporation or of any transfer agent for the Preferred Stock and shall
give written notice to the Corporation at such office that he elects to convert
the same (except that no such written notice of election to convert shall be
necessary in the event of an automatic conversion pursuant to Section 3(b)
hereof). The Corporation shall, as soon as practicable thereafter, issue and
deliver at such office to such holder of Series A Preferred or Series B
Preferred a certificate or certificates for the number of shares of Common Stock
to which such holder shall be entitled as aforesaid. Such conversion shall be
deemed to have been made immediately prior to the close of business on the date
of such surrender of the shares of Series A Preferred or Series B Preferred to
be converted (except that in the case of an automatic conversion pursuant to
Section 3(b) hereof such conversion shall be deemed to have been made
immediately prior to the closing of the offering referred to in Section 3(b))
and the person or persons entitled to receive the shares of Common Stock
issuable upon such conversion shall be treated for all purposes as the record
holder or holders of such shares of Common Stock on such date.

            1. Fractional Shares. In lieu of any fractional shares to which the
holder of Series A Preferred or Series B Preferred would otherwise be entitled,
the Corporation shall pay cash equal to such fraction multiplied by the fair
market value of one share of each such series of Preferred Stock as determined
by the Board of Directors of the Corporation. Whether or not fractional shares
are issuable upon such conversion shall be determined on the basis of the total
number of shares of Series A Preferred or Series B Preferred of each holder to
be converted at such time into Common Stock and the number of shares of Common
Stock issuable upon such aggregate conversion.

            1. Adjustment of Conversion Price. The applicable Conversion Price
of the Series A Preferred and the Series B Preferred shall be subject to
adjustment from time to time as follows:

                  a) If the Corporation shall issue any Common Stock other than
"Excluded Stock", as defined below, for a consideration per share less than the
applicable Conversion Price for such series in effect immediately prior to the
issuance of such Common Stock (excluding stock dividends, subdivisions,
split-ups, combinations, dividends or recapitalizations which are covered by
Section 3(e)(iii), (iv), (v) and (vi)), the Conversion Price in effect for each
such series immediately after each such issuance shall forthwith (except as
provided in this Section 3(e)) be adjusted to a price equal to the quotient
obtained by dividing:

                        (1) an amount equal to the sum of

                              (x) the total number of shares of Common Stock
outstanding (including any shares of Common Stock issuable upon conversion of
the Series A Preferred and Series B Preferred, or deemed to have been issued
pursuant to subdivision (3) of this clause (i) and to clause (ii) below)
immediately prior to such issuance multiplied by the Conversion Price in effect
for each such series immediately prior to such issuance, plus


                                      -5-
<PAGE>

                              (y) the consideration received by the Corporation
upon such issuance, by

                        (1) the total number of shares of Common Stock
outstanding (including any shares of Common Stock issuable upon conversion of
the Series A Preferred and Series B Preferred or deemed to have been issued
pursuant to subdivision (3) of this clause (i) and to clause (ii) below)
immediately prior to such issuance plus the additional shares of Common Stock
issued in such issuance (but not including any additional shares of Common Stock
deemed to be issued as a result of any adjustment in the Conversion Price
resulting from such issuance).

                  For purposes of any adjustment of the Conversion Price
pursuant to this clause (i), the following provisions shall be applicable:

                        (1) In the case of the issuance of Common Stock for
cash, the consideration shall be deemed to be the amount of cash paid therefor
after deducting any discounts or commissions paid or incurred by the Corporation
in connection with the issuance and sale thereof.

                        (2) In the case of the issuance of Common Stock for a
consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair market value thereof as determined by the
board of directors of the Corporation, in accordance with generally accepted
accounting treatment; provided, however, that if, at the time of such
determination, the Corporation's Common Stock is traded in the over-the-counter
market or on a national or regional securities exchange, such fair market value
as determined by the board of directors of the Corporation shall not exceed the
aggregate "Current Market Price" (as defined below) of the shares of Common
Stock being issued.

                        (3) In the case of the issuance of (i) options to
purchase or rights to subscribe for Common Stock (other than Excluded Stock),
(ii) securities by their terms convertible into or exchangeable for Common Stock
(other than Excluded Stock), or (iii) options to purchase or rights to subscribe
for such convertible or exchangeable securities:

                              (A) the aggregate maximum number of shares of
Common Stock deliverable upon exercise of such options to purchase or rights to
subscribe for Common Stock shall be deemed to have been issued at the time such
options or rights were issued and for a consideration equal to the consideration
(determined in the manner provided in subdivisions (1) and (2) above), if any,
received by the Corporation upon the issuance of such options or rights plus the
minimum purchase price provided in such options or rights for the Common Stock
covered thereby;

                              (B) the aggregate maximum number of shares of
Common Stock deliverable upon conversion of or in exchange for any such
convertible or exchangeable securities or upon the exercise of options to
purchase or rights to subscribe for such convertible or exchangeable securities
and subsequent conversion or exchange thereof, shall be deemed to have been
issued at the time such securities were issued or such options or rights were
issued and for a consideration equal to the consideration received by the
Corporation for any such securities and


                                      -6-
<PAGE>

related options or rights (excluding any cash received on account of accrued
interest or accrued dividends), plus the minimum additional consideration, if
any, to be received by the Corporation upon the conversion or exchange of such
securities or the exercise of any related options or rights (the consideration
in each case to be determined in the manner provided in subdivisions (1) and (2)
above);

                              (C) on any change in the number of shares of
Common Stock deliverable upon exercise of any such options or rights or
conversion of or exchange for such convertible or exchangeable securities, or on
any change in the minimum purchase price of such options, rights or securities,
other than a change resulting from the antidilution provisions of such options,
rights or securities, the Conversion Price shall forthwith be readjusted to such
Conversion Price as would have been obtained had the adjustment made upon (x)
the issuance of such options, rights or securities not exercised, converted or
exchanged prior to such change, as the case may be, been made upon the basis of
such change or (y) the options or rights related to such securities not
converted or exchanged prior to such change, as the case may be, been made upon
the basis of such change; and

                              (D) on the expiration of any such options or
rights, the termination of any such rights to convert or exchange or the
expiration of any options or rights related to such convertible or exchangeable
securities, the Conversion Price shall forthwith be readjusted to such
Conversion Price as would have been obtained had the adjustment made upon the
issuance of such options, rights, convertible or exchangeable securities or
options or rights related to such convertible or exchangeable securities, as the
case may be, been made upon the basis of the issuance of only the number of
shares of Common Stock actually issued upon the exercise of such options or
rights, upon the conversion or exchange of such convertible or exchangeable
securities or upon the exercise of the options or rights related to such
convertible or exchangeable securities, as the case may be.

                  a) "Excluded Stock" shall mean:

                        (1) all shares of Common Stock issued and outstanding on
the date this document is filed with the California Secretary of State and all
shares issuable upon exercise of options or warrants outstanding on the date
this document is filed with the California Secretary of State;

                        (1) all shares of Series A Preferred and Series B
Preferred and the Common Stock into which the shares of Series A Preferred and
Series B Preferred are convertible; and

                        (1) all shares of Common Stock, warrants or options to
purchase Common Stock or other securities issued to officers, directors,
consultants or employees of the Corporation pursuant to any plan or arrangement
approved by the board of directors of the Corporation.


                                      -7-
<PAGE>

                        All outstanding shares of Excluded Stock (including any
shares issuable upon conversion of the Preferred Stock) shall be deemed to be
outstanding for all purposes of the computations of Section 3(e)(i) above.

                  a) If the number of shares of Common Stock outstanding at any
time after the date hereof is increased by a stock dividend payable in shares of
Common Stock or by a subdivision or split-up of shares of Common Stock, then, on
the date such payment is made or such change is effective, the respective
Conversion Prices of Series A Preferred and Series B Preferred shall be
appropriately decreased so that the number of shares of Common Stock issuable on
conversion of any shares of such series of Series A Preferred and Series B
Preferred shall be increased in proportion to such increase of outstanding
shares of Common Stock.

                  a) If the number of shares of Common Stock outstanding at any
time after the date hereof is decreased by a combination of the outstanding
shares of Common Stock, then, on the effective date of such combination, the
respective Conversion Prices of Series A Preferred and Series B Preferred shall
be appropriately increased so that the number of shares of Common Stock issuable
on conversion of any shares of a series of Series A Preferred and Series B
Preferred shall be decreased in proportion to such decrease in outstanding
shares of Common Stock.

                  a) In case the Corporation shall declare a cash dividend upon
its Common Stock payable otherwise than out of retained earnings or shall
distribute to holders of its Common Stock shares of this capital stock (other
than Common Stock), stock or other securities of other persons, evidences of
indebtedness issued by the Corporation or other persons, assets (excluding cash
dividends) or options or rights (excluding options to purchase and rights to
subscribe for Common Stock or other securities of the Corporation convertible
into or exchangeable for Common Stock), then, in each such case, the holders of
shares of Series A Preferred and Series B Preferred shall, concurrent with the
distribution to holders of Common Stock, receive a like distribution based upon
the number of shares of Common Stock into which Series A Preferred or Series B
Preferred is convertible.

                  a) In case, at any time after the date hereof, of any capital
reorganization, or any reclassification of the stock of the Corporation (other
than as a result of a stock dividend or subdivision, split-up or combination of
shares), or the consolidation or merger of the Corporation with or into another
person (other than a consolidation or merger in which the Corporation is the
continuing entity and which does not result in any change in the Common Stock),
or of the sale or other disposition of all or substantially all the properties
and assets of the Corporation, the shares of Series A Preferred and Series B
Preferred shall, after such reorganization, reclassification, consolidation,
merger, sale or other disposition, be convertible into the kind and number of
shares of stock or other securities or property of the Corporation or otherwise
to which such holder would have been entitled if immediately prior to such
reorganization, reclassification, consolidation, merger, sale or other
disposition he had converted his shares of Series A Preferred or Series B
Preferred into Common Stock. The provisions of this clause (vi) shall similarly
apply to successive reorganizations, reclassifications, consolidations, mergers,
sales or other dispositions.

                  a) All calculations under this Section 3 shall be made to the
nearest cent or to the nearest one hundredth (1/100) of a share, as the case may
be.

                  a) For the purpose of any computation pursuant to this Section
3(e), the "Current Market Price" at any date of one share of Common Stock, shall
be deemed to be the average of the highest reported bid and the lowest reported
offer prices on the preceding business day as furnished by the National
Quotation Bureau, Incorporated (or equivalent recognized source of quotations);
provided, however, that if the Common Stock is not traded in such manner that
the quotations referred to in this clause (viii) are available for the period
required hereunder, Current Market Price shall be determined in good faith by
the Board of Directors of the Corporation, but if challenged by the holders of
more than 50% of the outstanding Series A Preferred and Series B Preferred,
voting as separate classes, then as determined by an independent appraiser
selected by the Board of Directors of the Corporation, the cost of such
appraisal to be borne by the challenging parties.

            1. Minimal Adjustments. No adjustment in the Conversion Price need
be made if such adjustment would result in a change in the Conversion Price of
less than $0.01. Any adjustment of less than $0.01 which is not made shall be
carried forward and shall be made at the time of and together with any
subsequent adjustment which, on a cumulative basis, amounts to an adjustment of
$0.01 or more in the Conversion Price.

            1. No Impairment. Without the consent of the majority of the
outstanding shares of Preferred Stock, the Corporation will not through any
reorganization, recapitalization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms to be observed
or performed hereunder by the Corporation, but will at all times in good faith
assist in the carrying out of all the provisions of this Section 3 and in the
taking of all such action as may be necessary or appropriate in order to protect
the Conversion Rights of the holders of Series A Preferred and Series B
Preferred against impairment.

            1. Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Conversion Rate pursuant to this Section 3,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Preferred Stock a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon written request at any time
of any holder of Series A Preferred or Series B Preferred, furnish or cause to
be furnished to such holder a like certificate setting forth (i) such
adjustments and readjustments, (ii) the Conversion Rate of such series at the
time in effect, and (iii) the number of shares of Common Stock and the amount,
if any, of other property which at the time would be received upon the
conversions of such holder's shares of Series A Preferred or Series B Preferred.

            1. Notices of Record Date. In the event of any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property or to receive any other right, the Corporation
shall mail to each holder of Series A Preferred and Series B Preferred at least
ten (10) days prior to such record date, a notice specifying the date on which
any such record is to be taken for the purpose of such dividend or distribution
or right, and the amount and character of such dividend, distribution or right.

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

            1. Notices. Any notice required by the provisions of this Section 3
to be given to the holder of shares of Series A Preferred and Series B Preferred
shall be deemed given if deposited in the United States mail, postage prepaid,
and addressed to each holder of record at his address appearing on the books of
the Corporation.

            1. Reissuance of Converted Shares. No shares of Series A Preferred
and Series B Preferred which have been converted into Common Stock after the
original issuance thereof shall ever again be reissued and all such shares so
converted shall upon such conversion cease to be a part of the authorized shares
of the Corporation.

      A. Voting Rights. The holder of each share of Series A Preferred and
Series B Preferred shall be entitled to the number of votes equal to the number
of shares of Common Stock into which each share of Series A Preferred and Series
B Preferred could be converted on the record date for the vote or consent of
shareholders written consent and, except as otherwise required by law or
provided for herein, shall have voting rights and powers equal to the voting
rights and powers of the Common Stock. The holder of each share of Series A
Preferred and Series B Preferred shall be entitled to notice of any
shareholders' meeting in accordance with the bylaws of the Corporation and shall
vote with holders of the Common Stock upon the election of directors, except as
provided in Section 5 herein, and upon any other matter submitted to a vote of
shareholders, except those matters required by law to be submitted to a class
vote. Fractional votes shall not, however, be permitted and any fractional
voting rights resulting from the above formula (after aggregating all shares of
Common Stock into which shares of Series A Preferred and Series B Preferred held
by each holder could be converted) shall be rounded to the nearest whole number
(with one-half rounded upward to one).


                                      -10-

      5. Election of Directors. At each election of the Corporation's directors,

accordance with Section 708 of the California Corporations Code) to elect one
(1) member of the Board of Directors, (ii) the holders of the Corporation's
Series B Preferred shall have the right, voting as a separate class (with

voting as a single class.

required by law, so long as any shares of Preferred Stock are outstanding, this
Corporation shall not without first obtaining the approval (by vote or written
consent, as provided by law) of the holders of at least a majority of the then
outstanding shares of Preferred Stock:

            1. sell, convey or otherwise dispose of all or substantially all of
its property or business, or merge into or effect a reorganization with any

parent) immediately after the transaction;

            1. change the rights, preferences, privileges or restrictions of the
Preferred Stock;

            1. pay any dividend on or purchase, redeem or otherwise acquire any

                                      -11-
<PAGE>

      7. Repurchase of Shares. In connection with repurchases by this
Corporation of its Common Stock, pursuant to its agreements with certain of the
holders thereof, Sections 502 and 503 of the California General Corporation Law
shall not apply in whole or in part with respect to such repurchases.

      8. Series B Preferred - Right of Redemption.

            (a) The Corporation shall be obligated to redeem the Series B
Preferred as follows:

                  a) The holders of at least a majority of the then outstanding
shares of Series B Preferred may require the Corporation to the extent it may
lawfully do so, to redeem, the Series B Preferred in three (3) annual
installments beginning on the seventh anniversary of the first issuance of the
Series B Preferred, and ending on two (2) years from such first redemption date
(each a "Redemption Date"). The Corporation shall effect such redemptions on the
applicable Redemption Date by paying in cash in exchange for the shares of
Series B Preferred to be redeemed a sum equal to the fair market value per share
of Series B Preferred plus declared and unpaid dividends with respect to such
shares. The fair market value per share of Series B Preferred for the purposes
of this Section 8, shall be determined by the Board of Directors of the
Corporation. If such determination is unacceptable to the holders of a majority
of the Series B Preferred, then the fair market value per share of Series B
Preferred shall be determined by an investment banking firm mutually acceptable
to the Corporation and the holders of a majority of the Series B Preferred. The
total amount to be paid for the Series B Preferred is hereinafter referred to as
the "Redemption Price." The number of shares of Series B Preferred that the
Corporation shall be required to redeem on any one Redemption Date shall be
equal to the amount determined by dividing (i) the aggregate number of shares of
Series B Preferred outstanding immediately prior to the Redemption Date by (ii)
the number of remaining Redemption Dates (including the Redemption Date to which
such calculation applies). Shares subject to redemption pursuant to this Section
8(a) shall be redeemed from each holder of Series B Preferred on a pro rata
basis.

                  a) At least thirty (30) days but no more than sixty (60) days
prior to the first Redemption Date, the Corporation shall send a notice (a
"Redemption Notice") to all holders of Series B Preferred to be redeemed setting
forth (a) the Redemption Price for the shares to be redeemed, and (b) the place
at which such holders may obtain payment of the Redemption Price upon surrender
of their share certificates. If the Corporation does not have sufficient funds
legally available to redeem all shares to be redeemed at the Redemption Date
(including, if applicable, those to be redeemed at the option of the
Corporation), then it shall redeem such shares pro rata (based on the portion of
the aggregate Redemption Price payable to them) to the extent possible and shall
redeem the remaining shares to be redeemed as soon as sufficient funds are
legally available.

            (b) On or prior to the Redemption Date, the Corporation shall
deposit the Redemption Price of all shares to be redeemed with a bank or trust
corporation having aggregate capital and surplus in excess of $100,000,000, as a
trust fund, with irrevocable instructions and authority to the bank or trust
corporation to pay, on and after such Redemption Date, the


                                      -12-
<PAGE>

Redemption Price of the shares to their respective holders upon the surrender of
their share certificates. Any moneys deposited by the Corporation pursuant to
this paragraph 8(b) for the redemption of shares thereafter converted into
shares of Common Stock pursuant to Section 3 hereof no later than the fifth
(5th) day preceding the Redemption Date shall be returned to the Corporation
forthwith upon such conversion. The balance of any funds deposited by the
Corporation pursuant to this Section 8(b) remaining unclaimed at the expiration
of one (1) year following such Redemption Date shall be returned to the
Corporation promptly upon its written request.

            (c) On or after such Redemption Date, each holder of shares of
Series B Preferred to be redeemed shall surrender such holder's certificates
representing such shares to the Corporation in the manner and at the place
designated in the Redemption Notice, and thereupon the Redemption Price of such
shares shall be payable to the order of the person whose name appears on such
certificate or certificates as the owner thereof and each surrendered
certificate shall be canceled. In the event less than all the shares represented
by such certificates are redeemed, a new certificate shall be issued
representing the unredeemed shares. From and after such Redemption Date, unless
there shall have been a default in payment of the Redemption Price or the
Corporation is unable to pay the Redemption Price due to not having sufficient
legally available funds, all rights of the holders of such shares as holders of
Series B Preferred (except the right to receive the Redemption Price without
interest upon surrender of their certificates), shall cease and terminate with
respect to such shares, provided that in the event that shares of Series B
Preferred are not redeemed due to a default in payment by the Corporation or
because the Corporation does not have sufficient legally available funds, such
shares of Series B Preferred shall remain outstanding and shall be entitled to
all of the rights and preferences provided herein.

            (d) In the event of a call for redemption of any shares of Series B
Preferred, the Conversion Rights (as defined in Section 3) for such Series B
Preferred shall terminate as to the shares designated for redemption at the
close of business on the fifth (5th) day preceding the Redemption Date, unless
default is made in payment of the Redemption Price.

                                       V.

      I. Limitation of Directors' Liability. The liability of the directors of
this Corporation for monetary damages shall be eliminated to the fullest extent
permissible under California law.

      I. Indemnification of Corporate Agents. This Corporation is authorized to
indemnify its agents to the fullest extent permissible under California law. For
purposes of this provision the term "agent" has the meaning set forth in Section
317 of the California Corporations Code.

      I. Repeal or Modification. Any repeal or modification of the foregoing
provisions of this Article V shall not adversely affect any right of
indemnification or limitation of liability of an agent of this Corporation
relating to acts or omissions occurring prior to such repeal or modification.

Preferred Stock Purchase Agreement dated February 14, 1997 (the "Agreement").

      The section numbers in this Schedule of Exceptions correspond to the

      2.1 Organization and Standing; Certificate and Bylaws.

      The Company is not qualified to do business in any state other than

former Indian subsidiary called Inventa Software India Pvt. Ltd. (now called
Ventura Data Systems Pvt. Ltd. since the Company's divestiture of its ownership)

tax liability, including penalties will not exceed $150,000.

      The Company has entered into a settlement agreement (the "Settlement
Agreement") with Resource Support Associates. The Settlement Agreement prohibits

plan for key management employees (the "KMIP") which provides for bonus payments
to participants of the KMIP upon the attainment of specific performance
criteria.

      Subsequent to July 8, 1994, every United States employee and consultant
with access to confidential or proprietary information of the Company has

cancellation notice from a customer of the Company called Alltel Healthcare

revenue by $150,000 and $250,000 in the first quarter of 1997 and the fiscal
year 1997, respectively. The Company estimates that its cash flow will be

                              INVENTA CORPORATION

                             SHAREHOLDERS AGREEMENT

      THIS SHAREHOLDERS AGREEMENT is made this 14th day of February, 1997,
between Inventa Corporation, a California corporation (the "Company"), the
purchasers of the Company's Series B Preferred Stock (the "Purchasers") as
listed on Exhibit A attached hereto, Ashok K. Santhanam ("Founder"), the holders
of the Company's Series A Preferred Stock (the "Series A Holders") listed on
Exhibit B attached hereto, and certain holders of the Company's Common Stock
(the "Common Holders") as listed on Exhibit C attached hereto. The Series A
Holders and the Common Holders shall collectively be referred to as the
"Shareholders".

      WHEREAS, Founder is the owner of 4,500,000 shares of the Common Stock of
the Company.

      WHEREAS, the Series A Holders and the Company are parties to the Series A
Preferred Stock Purchase Agreement dated July 8, 1994 (the "Series A
Agreement").

      WHEREAS, the Series A Holders desire to amend and restate, in its
entirety, Section 8 of the Series A Agreement in accordance with the terms of
the Agreement herein.

      WHEREAS, the Common Holders are the owners of 42,696 shares of the Common
Stock of the Company.

      WHEREAS, the Purchasers have requested, as a condition to entering into
the Series B Convertible Preferred Stock Purchase Agreement of even date
herewith (the "Series B Agreement") that the Founder and the Shareholders enter
into this Agreement, and the Founder and the Shareholders, as an inducement to
the Purchasers to enter into the Series B Agreement of even date herewith, are
willing to enter into this Agreement.

      NOW, THEREFORE, in consideration of the premises, mutual covenants and
terms hereof, the receipt and sufficiency of which is hereby acknowledged, the
parties agree as follows:

                                   I. ARTICLE

                   Right of First Refusal on Founder Transfer

      A. Company RightCompany RightCompany Right. If at any time Founder desires
(or is required) to sell or transfer in any manner any Shares (as hereinafter
defined) pursuant to the terms of a bona fide offer received from a third party
(a "Buyer"), the Founder shall submit a written offer to sell such Shares (the
"Offered Shares") to the Company on terms and conditions, including price, not
less favorable to the Company than those on which the Founder proposes to sell
such Offered Shares to such third party (the "Offer"). The Offer shall disclose
the identity of the proposed purchaser or transferee, the number of Offered
Shares, the terms of the proposed sale or transfer and any other material facts
relating to the sale or transfer. Within fifteen
<PAGE>

(15) days after receipt of the Offer, the Company shall give notice to the
Founder of its intent to purchase all or some of the Offered Shares from the
Founder on the terms and conditions set forth in the Offer.

      A. Purchasers' Right. If, for any reason whatsoever, the Company shall not
exercise its right to purchase all of the Offered Shares as provided herein, the
Company shall promptly provide to the Purchasers, written notice (the "Notice")
of same (which shall include a copy of the written offer provided to the Company
pursuant to Section 1.1 hereof), and then the Purchasers shall have the right,
on a pro rata basis, to purchase, on the same terms and conditions set forth in
the Offer, that portion of the Offered Shares which the Company shall not have
agreed to purchase from the Founder (all such remaining Shares being referred to
as the "Remaining Offered Shares"). For purposes of this Section 1.2,
Purchaser's pro rata right shall be calculated by dividing the number of shares
of Series B Preferred Stock held by such Purchaser by the total number of shares
of Series B Preferred Stock held by all Purchasers.

      A. Aggregation. For the purposes of this Article I, the number of shares
of Preferred and/or Common Stock issued upon conversion of Preferred shall
include the holdings of subsidiaries or parents or shareholders of the
Purchasers (or any entities which have the same parent corporation as the
Purchasers) and such holdings shall be aggregated together and with the
Purchasers.

      A. Failure to Exercise Rights. In the event that the Company and the
Purchasers, taken together, do not purchase all of the Offered Shares pursuant
to and within the time periods set forth above, any remaining Offered Shares may
be sold or transferred by the Founder at any time within 90 days thereafter,
subject to compliance with Section 2. Any such sale or transfer shall be at not
less than the price nor upon other terms and conditions, if any, not more
favorable to the purchaser or transferee than those specified in the Offer. Any
Offered Shares not sold within such 90-day period shall thereafter again be
subject to the requirements of this Article I. In the event that Shares are sold
or transferred to the Purchasers pursuant to this subsection, said Offered
Shares shall no longer be subject to this Agreement.

      A. Price. With respect to any stock to be transferred pursuant to Section
1.1 hereof and as to which a price has not been set by the Founder under Section
1.1 hereof, the price per Share shall be a price set by the Board of Directors
of the Company which will reflect the current value of the Shares in terms of
present earnings and future prospects of the Company. The Company shall notify
the Founder or the Founder's transferee of the price so determined within
fifteen (15) days after receipt by it of written notice of the transfer or
proposed transfer of the Offered Shares. If the Founder or the Founder's
transferee disputes the price as set by the Board of Directors by giving notice
to the Company within ten (10) days after being informed of the price, the price
of the Shares shall be determined by an independent financial analyst selected
by the Board of Directors of the Company, with the cost of such determination to
be divided equally between the Company and the Founder. The Board of Directors
shall select such analyst within fifteen (15) days after receipt of notice that
the Founder is disputing the price set by the Board of Directors. If the Board
is not notified of any such dispute within such ten (10) day period, the
decision of the Board of Directors as to the purchase price shall be final. Any
time required to determine a purchase price or to resolve a dispute shall be
added to the fifteen (15) day period in which the Company may exercise its right
to purchase.

      A. Transfer of Rights. The right of the Purchasers to purchase Offered
Shares hereunder may not be assigned except to a transferee or assignee who
qualifies as a subsidiary of one of the Purchasers, or a parent of one of the
Purchasers, or any entity which has the same parent corporation as one of the
Purchasers.

      A. Prohibited Transfers. The Founder shall not sell, assign, transfer,
pledge, hypothecate, mortgage or dispose of, by gift or otherwise, or in any way
encumber, all or any part of the Shares owned by him during the term of this
Agreement other than in compliance with the terms of this Article I.

      A. Definition of "Shares". For purposes of this Article I, the term
"Shares" shall mean and include all shares of capital stock of the Company owned
by the Founder, whether presently held or hereafter acquired.

Article I shall not apply to: (a) any transfer of Shares by the Founder by gift
or bequest or through inheritance to, or for the benefit of, any family member;
(b) any transfer of Shares by the Founder to a trust for the benefit of any
family member; (c) any sale or transfer of Shares to the Company (or any
assignee of the Company) pursuant to the terms of a stock restriction or stock
repurchase agreement (which provides for such sale upon the Founder's
termination of employment); (d) any sale of Common Stock in a public offering
pursuant to a registration statement filed by the Company with the Securities
and Exchange Commission; (e) any pledge made pursuant to a bona fide loan
transaction that creates a mere security interest; or (f) any bona fide gift. In
the event of any transfer pursuant to (a) or (b), the transferee of the Shares
shall hold the Shares so acquired with all the rights conferred by, and subject
to all the restrictions imposed by, this Agreement.

Founder desires (or is required) to sell or transfer in any manner any Shares
(as hereinafter defined) pursuant to the terms of a bona fide offer received
from a Buyer, and the Company and the Purchasers do not exercise their right of
first refusal as to all of the Offered Shares as set forth in Article I hereof,
each Purchaser shall have the right (the "Right of Co-Sale") to require, as a
condition to such sale or transfer, that the Buyer purchase from each Purchaser
at the same price per share and on the same terms and conditions as involved in
such sale or disposition by the Founder that percentage of the Offered Shares
not purchased by the Company or the Purchasers pursuant to Article I above,
expressed by a fraction, the numerator of which is the number of shares of
Preferred (on an as-converted into Common Stock basis) and Common Stock held by
such Purchaser and the denominator of which is the aggregate number of shares of
Preferred (on an as-converted into Common Stock basis) and Common Stock held by
all Purchasers and the number of Shares held by the Founder. The Purchasers
shall act upon the Buyer's offer to buy as soon as practicable after receipt
from the Company of the Notice and in all events within fifteen (15) days after
receipt of the Notice. In the


                                      -3-
<PAGE>

event that the Purchasers shall elect to exercise their Right of Co-Sale, the
Purchasers shall communicate in writing such election to the Founder.

      A. Agreement not to Transfer. The Founder shall not sell, assign,
transfer, pledge, hypothecate, mortgage or dispose of, by gift or otherwise, or
in any way encumber, all or any part of the Shares (as hereinafter defined)
owned by him during the term of this Agreement other than in compliance with the
terms of this Article II.

member; (c) any sale or transfer of Shares to the Company pursuant to the terms
of a stock restriction or stock repurchase agreement (which provides for such
sale upon the Founder's termination of employment); (d) the Company or the
Purchasers pursuant to the provisions of Article I hereof; (e) any sale of
Common Stock in a public offering pursuant to a registration statement filed by
the Company with the Securities and Exchange Commission; (f) any pledge made
pursuant to a bona fide loan transaction that creates a mere securities
interest; or (g) any bona fide gift. In the event of any transfer pursuant to
(a) or (b) the transferee of the Shares shall hold the Shares so acquired with
all the rights conferred by, and subject to all the restrictions imposed by,
this Agreement.

      A. Prohibited Transfers.

            1. In the event that a Founder should sell any Shares in
contravention of the co-sale rights of each Purchaser under this Agreement (a
"Prohibited Transfer"), each Purchaser, in addition to such other remedies as
may be available at law, in equity or hereunder, shall have the put option
provided below, and such Founder shall be bound by the applicable provisions of
such option.

            1. In the event of a Prohibited Transfer, each Purchaser shall have
the right to sell to such Founder the type and number of shares of Common Stock
equal to the number of shares each Purchaser would have been entitled to
transfer to the purchaser under Section 2(c) hereof had the Prohibited Transfer
been effected pursuant to and in compliance with the terms hereof. Such sale
shall be made on the following terms and conditions:

                  (a) The price per share at which the shares are to be sold to
the Founder shall be equal to the price per share paid by the purchaser to such
Founder in such Prohibited Transfer. The Founder shall also reimburse each
Purchaser for any and all fees and expenses, including legal fees and expenses,
incurred pursuant to the exercise or the attempted exercise of the Purchaser's
rights under this Article II.

<PAGE>

                  (a) Within ninety (90) days after the date on which a
Purchaser received notice of the Prohibited Transfer or otherwise became aware
of the Prohibited Transfer, such Purchaser shall, if exercising the option
created hereby, deliver to the Founder the certificate or certificates
representing the shares to be sold, each certificate to be properly endorsed for
transfer.

                  (a) Such Founder shall, upon receipt of the certificate or
certificates for the shares to be sold by a Purchaser, pursuant to this Section
2.5(b), pay the aggregate purchase price therefor and the amount of reimbursable
fees and expenses, as specified in Section 2.5(b)(i), in cash or by other means
acceptable to the Purchaser.

                  (a) Notwithstanding the foregoing, any attempt by a Founder to
transfer Co-Sale Stock in violation of Article II hereof shall be voidable at
the option of a majority in interest of the Purchasers if the Purchasers do not
elect to exercise the put option set forth in this Section 2.5, and the Company
agrees it will not effect such a transfer nor will it treat any alleged
transferee as the holder of such shares without the written consent of a
majority in interest of the Purchasers.

                                   I. ARTICLE

                                 Tag Along Right

      A. In the event that shareholders owning at least fifty percent (50%) of
the total number of shares of capital stock of the Company held by all
shareholders (on a fully diluted basis) (the "Proposing Shareholders") shall
have approved in writing a transaction or series of related transactions with
any person or entity regarding a sale of shares held by such Proposing
Shareholders such that any one outside shareholder shall gain a majority of the
outstanding shares of the Company after the closing of such transaction, the
remaining shareholders of the Company ("Remaining Shareholders") shall be
entitled, at their option, to include, at most, the same percentage of their
respective shares in such transfer as the percentage of the respective shares
proposed to be sold by the Proposing Shareholders. The Proposing Shareholders
shall provide to each Remaining Shareholder a notice (the "Tag Along Notice"),
at least thirty (30) days prior to the consummation of the proposed transaction,
setting forth in reasonable detail the material terms and conditions of the
proposed transaction and the price per share at which the Remaining Shareholders
may sell their shares (which price shall be equal to the price at which such
Proposing Shareholders have agreed to sell their shares) (such entitlement shall
be referred to herein as the "Tag Along Rights"). Upon receipt of the Tag Along
Notice, each of the Remaining Shareholders who elects to participate in the
proposed transaction shall provide to the Proposing Shareholders a notice, at
least fifteen (15) days prior to the consummation of the proposed transaction,
of his or her intention to exercise the Tag Along Rights. If no such notice is
given to the Proposing Shareholders, the Tag Along Rights for the particular
Remaining Shareholder shall expire.

      1. At the closing of the proposed transaction (which date, place and time
shall be designated by the Proposing Shareholders and provided to each other
Remaining Shareholder in writing at least five (5) business days prior thereto),
each such other Remaining Shareholder shall deliver certificates evidencing all
its shares, duly endorsed, or accompanied by written instruments of transfer


                                      -5-
<PAGE>

in form satisfactory to the proposed purchaser, duly executed, by such Remaining
Shareholder, free and clear of any liens, against delivery of the purchase price
therefor.

            1. The Tag Along Rights shall not apply to a disposition by any
shareholder to (a) any other shareholder of the Company or (b) an affiliate of
the disposing shareholder (including any family member of a shareholder or trust
for the benefit of a shareholder or family members), provided the transferee
agrees in writing to be subject to the terms and conditions of this Agreement as
if it were an original party thereto.

                                   I. ARTICLE

                   Right of First Refusal on Company Issuances

      A. Grant of Right. Except as set forth in Article V, the Company hereby
grants to each Series A Holder and each Purchaser (for purposes of this Article
IV, the Series A Holders and the Purchasers shall collectively be referred to as
the "Preferred Holders") who continues to hold, respectively, shares of Series A
Preferred Stock purchased pursuant to the Series A Agreement and Series B
Preferred Stock purchased pursuant to the Series B Agreement (the "Preferred
Shares"), the right of first refusal to purchase all or any part of such
Preferred Holder's Pro Rata Share (as hereinafter defined) of the New Securities
(as defined in Section 4.2) which the Company may, from time to time, propose to
sell and issue. The Preferred Holders may purchase said New Securities on the
same terms and at the same price at which the Company proposes to sell the New
Securities. The "Pro Rata Share" of each Preferred Holder, for purposes of this
right of first refusal, is the ratio of the total number of shares of Common
Stock held by such Preferred Holder, including (i) any shares of Common Stock
into which shares of Preferred Stock held by such Preferred Holder are
convertible, and (ii) any shares deliverable upon the exercise of options of
other rights to purchase Common Stock held by such Preferred Holder, to the
total number of shares of Common Stock outstanding immediately prior to the
issuance of the New Securities (including (i) any shares of Common Stock into
which outstanding shares of Preferred Stock are convertible and (ii) any shares
deliverable upon the exercise of options or other rights to purchase Common
Stock).

      A. New Securities. "New Securities" shall mean any capital stock of the
Company, whether now authorized or not, and any rights, options or warrants to
purchase said capital stock, and securities of any type whatsoever that are, or
may become, convertible into said capital stock; provided, however, that "New
Securities" does not include (i) the Preferred Shares purchased pursuant to the
Series B Agreement or other securities issued or issuable upon conversion of the
Preferred Shares ("Conversion Shares"), (ii) securities offered pursuant to a
registration statement filed under the Securities Act of 1933, as amended (the
"Act"), (iii) securities issued pursuant to the acquisition of another
corporation by the Company by merger, purchase of substantially all of the
assets or other reorganization, (iv) shares offered pursuant to lease financing
transactions or bank or lending institution financing transactions that are
approved by the Board of Directors, (v) securities issued in connection with any
stock split, stock dividend or recapitalization of the Company, (vi) all
securities hereafter issued or issuable to officers, directors, employees or
consultants of the Company (for the primary purpose of soliciting or retaining


                                      -6-
<PAGE>

their employment or services) pursuant to any employee or consultant stock
offering, plan or arrangement approved by the Board of Directors, (vii) Series A
Preferred Stock issued upon conversion of the Series A Preferred warrant, and
(viii) Common Stock issued upon conversion of the Preferred Shares.

      A. Notice. In the event the Company proposes to undertake an issuance of
New Securities, it shall give to the Preferred Holders written notice (the
"Notice") of its intention, describing the type of New Securities, number of
shares, the price, the terms upon which the Company proposes to issue the same,
and notice to the effect that each Preferred Holder must respond to such Notice
within thirty (30) days after the date thereof. The Preferred Holders shall have
thirty (30) days from the date of such Notice to purchase any or all of the New
Securities for the price and upon the terms specified in the Notice by giving
written notice to the Company and stating therein the quantity of New Securities
to be purchased and forwarding payment for such New Securities to the Company if
immediate payment is required by such terms, or in any event no later than
forty-five (45) days after the date of the Notice.

      A. Sale after Notice. In the event any Preferred Holder fails to exercise
in full the right of first refusal within said thirty (30) day period, the
Company shall have ninety (90) days thereafter to sell or enter into an
agreement (pursuant to which the sale of New Securities covered thereby shall be
closed, if at all, within thirty (30) days from the date of said agreement) to
sell the New Securities respecting which such Preferred Holder's rights were not
exercised, at a price and upon general terms no more favorable to the Preferred
Holders thereof than specified in the Notice. In the event the Company has not
sold the New Securities within said ninety (90) day period (or sold and issued
New Securities in accordance with the foregoing within thirty (30) days from the
date of said agreement), the Company shall not thereafter issue or sell any New
Securities without first offering such securities to the Preferred Holders in
the manner provided above.

      A. Assignment. The right of first refusal granted under this Article IV is
assignable by the Preferred Holders to any transferee of a minimum of fifty
thousand (50,000) shares of Series A Preferred Stock (as adjusted for any stock
split, stock dividends, combinations, recapitalizations and the like with
respect to such shares) or fifty thousand (50,000) shares of Series B Preferred
Stock (as adjusted for any stock split, stock dividends, combinations,
recapitalizations and the like with respect to the shares), as applicable, or
the Common Stock into which they has been converted.

      The Right of First Refusal on Founder Transfer, Co-Sale Right, Tag Along
Right, and Right of First Refusal on Company Issuances created under Articles I,
II, III and IV of this Agreement, respectively, shall expire upon (i) the
closing of the first public offering of the Common Stock of the Company to the
general public which is effected pursuant to a registration statement filed
with, and declared effective by, the Securities and Exchange Commission under
the Securities Act of 1933, as amended; (ii) upon the closing of a transaction
or series of related transactions (including, without limitation, any
reorganization, merger or consolidation) which results in (a) the holders of the
outstanding voting equity


                                      -7-

securities of the Company immediately prior to such transaction or series of
related transactions holding securities representing less than 50% of the voting
power of the surviving entity immediately following such transaction or series
of related transactions or (b) the sale or disposition by the Company of all or
substantially all the Company's assets; or (iii) with respect to the Right of
First Refusal on Founder Transfer, the date on which less than 50% of the Series
B Preferred Stock of the Company initially issued remains outstanding (as
adjusted for any stock split, stock dividends, combinations, recapitalizations
and the like with respect to the shares).

                               Board of Directors

      The Purchasers, the Founder and the Shareholders each agree to hold all
shares of voting capital stock of the Company now owned or hereinafter acquired
by them (including but not limited to all shares of Common Stock issued upon
conversion of the Company's Series A and B Preferred Stock) registered in their
respective names or beneficially owned by them as of the date hereof (and any
and all other securities of the Company legally or beneficially acquired by each
of the Purchasers, the Founder and the Shareholders after the date hereof)
subject to, and to vote their shares of the Company's voting securities in
accordance with, the provisions of this Agreement.

      At each election of directors in which the holders of Common Stock and
holders of Preferred Stock, voting together as a single class, are entitled to
elect directors of the Company, the Purchasers, the Founder and the Shareholders
shall consult each other and shall vote their respective shares of the Company's
voting stock so that such directors will be nominees that are mutually
acceptable to a majority in interest of the holders of Common Stock and
Preferred Stock and reasonably acceptable to the holders of Series B Preferred
Stock.

accordingly, the parties shall, in addition to such other remedies as may be
available to any of them at law or in equity, have the right to enforce their
rights hereunder by actions for specific performance to the extent permitted by
law.

Agreement. Nothing in this Agreement should be

expressly provided otherwise herein.

      9.5 Invalidity of Provisions. In the case any one or more of the
provisions contained in this Agreement shall for any reason be held to be
invalid, illegal or unenforceable in any respect, such invalidity, illegality or
unenforceability shall not affect any other provision of this Agreement and such
invalid, illegal and unenforceable provision shall be reformed and construed so
that it will be valid, legal, and enforceable to the maximum extent permitted by
law.

      9.6 Notice. Any notice, demand or request required or permitted to be
given by either the Company or the Founder or the Purchasers or the Shareholders
pursuant to the terms of this Agreement shall be in writing and shall be deemed
given when delivered personally or deposited in the U.S. mail, First Class with
postage prepaid, and addressed to the parties at the addresses of the parties
set forth at the end of this Agreement or such other address as a party may
request by notifying the other in writing.

      9.7 No Waiver. Any party's failure to enforce any provision or provisions
of this Agreement shall not in any way be construed as a waiver of any such
provision or provisions, nor prevent that party thereafter from enforcing each
and every other provision of this Agreement. The rights granted to the parties
herein are cumulative and shall not constitute a waiver of any party's right to
assert all other legal remedies available to it under the circumstances.

      9.8 Cooperation. The parties agree upon request to execute any further
documents or instruments necessary or desirable to carry out the purposes or
intent of this Agreement.

      The undersigned hereby acknowledges receipt and review of the Shareholders
Agreement dated February 14, 1997 (the "Agreement"). By signing below, the
undersigned agrees to be bound by the terms of the Agreement as if the
undersigned was an original party thereto. The undersigned further agrees that

                                February 12, 1997

To:   Each Investor listed on
      the Schedule of Investors
      to the Inventa Corporation
      Series B Convertible Preferred
      Stock Purchase Agreement

Ladies and Gentlemen:

      Reference is made to the Series B Convertible Preferred Stock Purchase
Agreement dated as of February 14, 1997 (the "Agreement"), complete with all
listed exhibits thereto, by and among Inventa Corporation, Inc., a California
corporation, (the "Company") and each of you, providing for the issuance by the
Company to the Investors of shares of Series B Preferred Stock of the Company
(the "Shares"). This opinion is rendered to you in compliance with Section 5.6
of the Agreement, and all terms used herein have the meanings defined for them
in the Agreement unless otherwise defined herein.

      We have acted as counsel for the Company in connection with the
negotiation of the Agreement and the issuance of the Shares. As such counsel, we
have made such legal and factual examinations and inquiries as we have deemed
advisable or necessary for the purpose of rendering this opinion. In addition,
we have examined originals or copies of such corporate records of the Company,
certificates of public officials and such other documents which we consider
necessary or advisable for the purpose of rendering this opinion. In such
examination we have assumed the genuineness of all signatures on original
documents, the authenticity and completeness of all documents submitted to us as
originals, the conformity to original documents of all copies submitted to us
and the due execution and delivery of all documents (except as to due execution
and delivery by the Company) where due execution and delivery are a prerequisite
to the effectiveness thereof.

      As used in this opinion, the expression "to our knowledge," "known to us"
or similar language with reference to matters of fact means that, after an
examination of documents made available to us by the Company, and after
inquiries of officers of the Company, but without any further independent
factual investigation, we find no reason to believe that the opinions expressed
herein are factually incorrect. Further, the expression "to our knowledge,"
"known to us" or similar language with reference to matters of fact refers to
the current actual knowledge of the attorneys of this firm who have worked on
matters for the Company. Except to the extent expressly set forth herein or as
we otherwise believe to be necessary to our opinion, we have not undertaken any
independent investigation to determine the existence or absence of
<PAGE>

any fact, and no inference as to our knowledge of the existence or absence of
any fact should be drawn from our representation of the Company or the rendering
of the opinion set forth below.

      For purposes of this opinion, we are assuming that you have all requisite
power and authority, and have taken any and all necessary corporate or
partnership action, to execute and deliver the Agreement, and we are assuming
that the representations and warranties made by the Investors in the Agreement
and pursuant thereto are true and correct. We are also assuming that each
Investor has purchased the Shares for value, in good faith and without notice of
any adverse claims within the meaning of the California Uniform Commercial Code.

      The opinions hereinafter expressed are subject to the following
qualifications:

            (a) We express no opinion as to the effect of applicable bankruptcy,
insolvency, reorganization, moratorium or other similar federal or state laws
affecting the rights of creditors;

            (b) We express no opinion as to the effect of rules of law governing
specific performance, injunctive relief or other equitable remedies (regardless
of whether any such remedy is considered in a proceeding at law or in equity);

            (c) We express no opinion as to compliance with the anti-fraud
provisions of applicable securities laws;

            (d) We express no opinion as to the enforceability of the
indemnification provisions of the Registration Rights Agreement, to the extent
the provisions thereof may be subject to limitations of public policy and the
effect of applicable statutes and judicial decisions; and

            (e) We are members of the Bar of the State of California and, except
as set forth in paragraph 5 below with respect to the securities laws of other
states, we express no opinion as to any matter relating to the laws of any
jurisdiction other than the federal laws of the United States of America and the
laws of the State of California. To the extent this opinion addresses applicable
securities laws of states other than the State of California, we have not
retained nor relied on the opinion of counsel admitted to the bar of such
states, but rather have relied on compilations of the securities laws of such
states contained in reporting services presently available to us.

      Based upon and subject to the foregoing, and except as set forth in the
Schedule of Exceptions to the Agreement, we are of the opinion that:

      1. The Company is a corporation duly organized and validly existing under,
and by virtue of, the laws of the State of California and is in good standing
under such laws. The Company has requisite corporate power to own and operate
its properties and assets, and to carry on its business as presently conducted.
The Company is duly qualified to do business, and in good standing in all
foreign jurisdictions where its ownership or leasing of properties or the
conduct of its business requires such qualification, except where the failure to
be so qualified would not have a material adverse effect on the Company's
business as now conducted.


                                       2
<PAGE>

      2. The Company has all requisite legal and corporate power to execute and
deliver the Agreement, the Shareholder Agreement and the Registration Rights
Agreement, to sell and issue the Shares under the Agreement, to issue the Common
Stock issuable upon conversion of the Shares and to carry out and perform its
obligations under the terms of the Agreement, the Shareholder, and the
Registration Rights Agreement.

      3. The authorized capital of the Company consists of (i) 3,560,000 shares
of Preferred Stock, 1,000,000 shares of which are designated Series A Preferred
Stock and of which 800,000 are issued and outstanding, and 2,560,000 shares of
which are designated Series B Preferred and of which none are issued and
outstanding, and (ii) 20,000,000 shares of Common Stock, of which 4,542,396
shares are issued and outstanding. All issued and outstanding shares of the
Company's capital stock have been duly authorized and validly issued and are
fully paid and nonassessable. The Shares, when issued pursuant to the terms of
the Agreement (including Common Stock issued upon conversion of the Shares),
will be duly authorized, validly issued, fully paid and nonassessable. Except as
set forth in the Agreement, the Shareholders Agreement, and the Registration
Rights Agreement and all the exhibits thereto, there are no options, warrants or
other rights (including conversion or preemptive rights) or agreements
outstanding to purchase any of the Company's authorized and unissued capital
stock.

      4. All corporate action on the part of the Company, its directors and
shareholders necessary for the authorization, execution, delivery and
performance of the Agreement, the Shareholders Agreement and the Registration
Rights Agreement, the authorization, sale, issuance and delivery of the Shares
and the performance of the Company's obligations under the Agreement, the
Shareholders Agreement, and the Registration Rights Agreement has been taken.
The Agreement, the Shareholders Agreement, and the Registration Rights Agreement
have been duly and validly executed and delivered by the Company and constitute
valid and binding obligations of the Company, enforceable against the Company in
accordance with their terms. The Shares will have the rights, preferences and
privileges described in the Restated Articles. To our knowledge, the Shares and
the Common Stock issuable on conversion of the Shares will be free of any liens,
encumbrances or preemptive rights contained in the Company's Restated Articles
or Bylaws.

      5. The execution, delivery and performance of and compliance with the
terms of the Agreement, and the issuance of the Shares do not violate any
provision of the Restated Articles or Bylaws, or, to our knowledge, any
provisions of any applicable federal or state law, rule or regulation. To our
knowledge, the execution, delivery and performance of and compliance with the
Agreement, the Shareholders Agreement, and the Registration Rights Agreement and
the issuance of the Shares do not violate or constitute a default under, any
material contract, agreement, instrument, judgment or decree binding upon the
Company.

      6. To our knowledge, there are no actions, suits, proceedings or
investigations pending against the Company or its properties before any court or
governmental agency (nor, to our knowledge, has the Company received any written
threat thereof), which, either in any case or in the aggregate, are likely to
result in any material adverse change in the business or financial condition of
the Company or any of its properties, or in any material impairment of the right
or ability of the Company to carry on its business as now conducted, or which
questions the validity of the Agreement, the Shareholders


                                       3
<PAGE>

Agreement or the Registration Rights Agreement or any action taken or to be
taken by the Company in connection therewith.

      7. No consent, approval or authorization of or designation, declaration or
filing with any governmental authority on the part of the Company is required in
connection with the valid execution and delivery of the Agreement, the
Shareholders Agreement, and the Registration Rights Agreement or other offer,
sale or issuance of the Shares or the consummation of any other transaction
contemplated thereby, except (a) filing of the Restated Articles in the Office
of the Secretary of State of the State of California, and (b) qualification (or
taking such action as may be necessary to secure an exemption from
qualification, if available) under the California Corporate Securities Law and
other applicable blue sky laws (but excluding jurisdictions outside of the
United States) of the offer and sale of the Shares (and the Common Stock
issuable upon conversion thereof) and the modification of rights of shareholders
contemplated by the Agreement. The filing referred to in clause (a) above has
been accomplished and is effective, and to our knowledge there are no
proceedings or written threat thereof which question the validity of such
filing. Our opinion herein is otherwise subject to the timely and proper
completion of all filings and other actions contemplated by clause (b) above
where such filings and actions are to be undertaken on or after the date hereof.

      8. Subject to the accuracy of each Investor's representations in Section 3
of the Agreement we are of the opinion that the offer, sale and issuance of the
Shares in conformity with the terms of the Agreement constitute transactions
exempt from the registration requirements of Section 5 of the Securities Act of
1933, as amended.

      This opinion is furnished to the Investors solely for their benefit in
connection with the purchase of the Shares, and may not be relied upon by any
other person or for any other purpose without our prior written consent.

                                    Very truly yours,


                                    WILSON, SONSINI, GOODRICH & ROSATI

                                   ---------


                AMENDED AND RESTATED ARTICLES OF INCORPORATION
                                      OF
                              INVENTA CORPORATION

                                      I.

     The name of this corporation is Inventa Corporation (the "Corporation").


                                      II.

     The purpose of this Corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of
California other than the banking business, the trust company business or the
practice of a profession permitted to be incorporated by the California
Corporations Code.


                                     III.

     This Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock."  The total
number of shares which the Corporation is authorized to issue is 33,119,511
shares, of which 25,000,000 shares shall be Common Stock with a par value of
$0.001 per share and of which 8,119,511 shares shall be Preferred Stock,
1,000,000 of which are designated Series A Preferred Stock with a par value of
$0.001 per share, 2,560,000 of which are designated Series B Preferred Stock
with a par value of $0.001 per share and 4,059,511 of which are designated
Series C Preferred Stock with a par value of $0.001 per share.  The Board of
Directors is authorized to fix the number of shares of any series of Preferred
Stock and to determine or alter the rights, preferences, privileges, and
restrictions granted to or imposed upon any wholly unissued series of Preferred
Stock and, within the limits and restrictions stated in any resolution or
resolutions of the Board of Directors originally fixing the number of shares
constituting any series of Preferred Stock, to increase or decrease (but not
below the number of shares of any such series then outstanding) the number of
shares of any such series subsequent to the issue of shares of that series.
<PAGE>

                                      IV.

     The rights, preferences, privileges and restrictions granted to or imposed
upon the Common Stock and Preferred Stock are as follows:

     1.   Dividend Provisions.  The holders of shares of Series A Preferred
          -------------------
Stock ("Series A Preferred"), Series B Preferred Stock ("Series B Preferred")
and Series C Preferred Stock ("Series C Preferred") shall be entitled to receive
dividends, out of any assets legally available therefor, prior and in preference
to any declaration or payment of any dividend (payable other than in Common
Stock or other securities and rights convertible into or entitling the holder
thereof to receive, directly or indirectly, additional shares of Common Stock of
this Corporation) on the Common Stock of this Corporation, at the rate of $0.03
per annum per share of Series A Preferred (as adjusted for any stock dividends,
combinations, splits, recapitalizations and the like with respect to such
shares), $0.075 per annum per share of Series B Preferred  (as adjusted for any
stock dividends, combinations, splits, recapitalizations and the like with
respect to such shares) and $0.10 per annum per share of Series C Preferred (as
adjusted for any stock dividends, combinations, splits, recapitalizations and
the like with respect to such shares) or, if greater (as determined on a per
annum basis and on an as converted basis for the Series A Preferred, Series B
Preferred and Series C Preferred), an amount equal to that paid on the Common
Stock. Such dividends shall be payable when, as, and if declared by the Board of
Directors, and shall not be cumulative, and no right shall accrue to holders of
Common Stock or Preferred Stock by reason of the fact that dividends on said
shares are not declared in any prior period.  After payment has been made to the
holders of Preferred Stock of the full amounts to which they shall be entitled
as set forth in this Section 1, the holders of Preferred Stock and Common Stock
shall be entitled to receive ratably on a per-share basis any remaining funds
declared as dividends.

     2.   Liquidation Preference.
          ----------------------

          (a)  Preferred Preference.  In the event of any liquidation,
               --------------------
dissolution, or winding up of the Corporation, either voluntary or involuntary,
the holders of the Series C Preferred shall be entitled to receive on a pro rata
basis, prior and in preference to any distribution of any of the assets or
surplus funds of the Corporation to the holders of the Series A Preferred,
Series B Preferred and Common Stock, by reason of their ownership of such stock,
an amount per share equal to the sum of $1.25 per share of Series C Preferred
(as adjusted for any stock dividends, combinations, splits, recapitalizations
and the like with respect to such shares) plus declared and unpaid dividends,
for each share of Series C Preferred then held by them.  If upon the occurrence
of such event, the assets and funds thus distributed among the holders of the
Series C Preferred shall be insufficient to permit the payment to such holders
of the full aforesaid preferential amounts, then the entire assets and funds of
the Corporation legally available for distribution shall be distributed among
the holders of the Series C Preferred in proportion to the number of shares of
Series C Preferred held by each such holder.

          (b)  After payment has been made to the holders of the Series C
Preferred of the full amount to which they shall be entitled as set forth in
paragraph 2(a) above, the holders of

                                      -2-
<PAGE>

Series A Preferred and Series B Preferred shall be entitled to receive, prior
and in preference to any distribution of any of the assets of this Corporation
to the holders of Common Stock by reason of their ownership thereof, an amount
per share equal to $0.50 for each outstanding share of Series A Preferred (as
adjusted for any stock dividends, combinations, splits, recapitalizations and
the like with respect to such shares), and $1.25 for each outstanding share of
Series B Preferred (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares), plus an amount
equal to any declared but unpaid dividends for each share of Series A Preferred
and Series B Preferred then held by them. If upon the occurrence of such event,
the assets and funds thus distributed among the holders of Series A Preferred
and Series B Preferred shall be insufficient to permit the payment to such
holders of the full aforesaid preferential amounts, then the entire assets and
funds of this Corporation legally available for distribution shall be
distributed ratably among the holders of the Series A Preferred and Series B
Preferred in proportion to the aggregate Series A Preferred liquidation
preference and the Series B Preferred liquidation preference.

          (c)  After payment has been made to the holders of the Preferred
Stock of the full amounts to which they shall be entitled to as set forth in
paragraphs 2(a) and 2(b) above, the holders of the Common Stock shall then be
entitled to receive the amount of $0.40 per share for each share of Common Stock
then held by them (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares), plus an amount
equal to all declared but unpaid dividends for each share of Common Stock then
held by them.  If the assets and funds thus distributed among the holders of the
Common Stock shall be insufficient to permit the payment to such holders of the
full aforesaid amount, then the entire assets and funds of the Corporation
legally available for distribution, shall be distributed among the holders of
the Common Stock ratably on a per-share basis.

          (d)  After payment has been made to the holders of the Preferred
Stock and the Common Stock of the full amount to which they shall be entitled as
set forth in paragraphs 2(a), 2(b) and 2(c)  above, the holders of the Preferred
Stock and Common Stock shall be entitled to receive ratably on a per-share basis
all the remaining assets based upon the number of shares of Common Stock into
which each share of Preferred Stock is then convertible; provided, however, that
the holders of Preferred Stock shall not be entitled to receive pursuant to this
paragraph (d) (including amounts received pursuant to paragraphs 2 (a) and 2(b)
above) more than a total of $1.00 per share of Series A Preferred, $2.50 per
share of Series B Preferred and $2.50 per share of Series C Preferred then held
by them (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares) plus declared and
unpaid dividends.

          (e)  After payment has been made to the holders of the Preferred
Stock and the Common Stock of the full amounts to which they shall be entitled
as set forth in paragraphs 2(a), 2(b), 2(c) and 2(d) above, the holders of the
Common Stock shall be entitled to receive ratably on a per-share basis all the
remaining assets.

                                      -3-
<PAGE>

          (f)  Mergers.  Unless waived by the approval (by vote or written
               -------
consent, as provided by law) of the holders of 66 2/3% of the then outstanding
Series C Preferred, for purposes of this Section 2, a merger or consolidation of
the Corporation with or into any other corporation or corporations, the merger
of any other corporation or corporations into the Corporation, in which the
shareholders of the Corporation receive distributions in cash or securities of
another corporation or corporations as a result of such consolidation or merger,
a reorganization, including a sale of the capital stock of the Corporation,
where the shareholders of the Corporation immediately prior to the transaction
possess less than 50% of the voting power of the surviving entity (or its
parent) immediately after the transaction, or a sale of all or substantially all
of the assets of the Corporation, shall be treated as a liquidation, dissolution
or winding up of the Corporation; provided that the holders of the Preferred
Stock and the Common Stock shall each be paid in cash or in the securities
received or in a combination thereof (which combination shall be in the same
proportions as the consideration received in the transaction). Any securities to
be delivered to the holders of the Preferred Stock and Common Stock upon merger,
reorganization or sale of substantially all the assets of the Corporation shall
be valued as follows:

               (i)    if traded on a securities exchange, the value shall be
deemed to be the average of the closing prices of the securities on such
exchange over the 30-day period ending three (3) business days prior to the
closing;

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

               (iii)  if there is no active public market, the value shall be
the fair market value thereof as mutually determined by the Corporation and the
holders of not less than a majority of the outstanding shares of the Preferred
Stock, provided that if the Corporation and the holders of a majority of the
outstanding shares of the Preferred Stock are unable to reach agreement, then by
independent appraisal by an investment banker hired and paid by the Corporation,
but acceptable to the holders of a majority of the outstanding shares of
Preferred Stock.

          (g)  As authorized by Section 402.5(c) of the California Corporations
Code, the provisions of Sections 502 and 503 of the California Corporations Code
shall not apply with respect to repurchase by the Corporation of shares of
Common Stock issued to or held by employees or consultants of the Corporation or
its subsidiaries upon termination of their employment or services pursuant to
agreement providing for the right of said repurchase.

     3.   Conversion.  The holders of the Series A Preferred, Series B
          ----------
Preferred and Series C Preferred shall have conversion rights as follows (the
"Conversion Rights"):

          (a)  Right to Convert.  Each share of Series A Preferred, Series B
               ----------------
Preferred and Series C Preferred shall be convertible into share(s) of Common
Stock without the payment of any additional consideration by the holder thereof
and, at the option of the holder thereof, at any time after the date of issuance
of such share, at the office of the Corporation or any transfer agent for the

                                      -4-
<PAGE>

Series A Preferred, Series B Preferred and Series C Preferred.  Each share of
Series A Preferred, Series B Preferred and Series C Preferred shall be
convertible into the number of fully paid and nonassessable shares of Common
Stock which results from dividing the Conversion Price (as hereinafter defined)
per share in effect for the Series A Preferred, Series B Preferred and Series C
Preferred at the time of conversion into the per share Conversion Value (as
hereinafter defined) of such series.  The initial Conversion Price per share of
Series A Preferred shall be $.50, and the Conversion Value per share of the
Series A Preferred shall be $.50.  The initial Conversion Price per share of the
Series B Preferred shall be $1.25, and the Conversion Value per share of the
Series B Preferred shall be $1.25.  The initial Conversion Price per share of
the Series C Preferred shall be $1.25, and the Conversion Value per share of the
Series C Preferred shall be $1.25. The initial Conversion Price of Series A
Preferred, Series B Preferred and Series C Preferred shall be subject to
adjustment from time to time as provided below.  The number of shares of Common
Stock into which a share of Series A Preferred, Series B Preferred and Series C
Preferred is convertible is hereinafter referred to as the "Conversion Rate" of
such series.

          (b)  Automatic Conversion.  Each share of Series A Preferred shall
               --------------------
automatically be converted into shares of Common Stock at the applicable
effective Conversion Rate immediately upon the closing of a firm commitment
underwritten public offering pursuant to an effective registration statement
under the Securities Act of 1933, as amended, covering the offer and sale of
Common Stock in which (a) the public offering price equals or exceeds $1.75 per
share (adjusted to reflect subsequent stock dividends, stock splits or
recapitalization) and (b) the aggregate proceeds raised equals or exceeds
$5,000,000.

               Each share of Series B Preferred and Series C Preferred shall
automatically be converted into shares of Common Stock at the applicable
effective Conversion Rate immediately upon the closing of a firm commitment
underwritten public offering pursuant to an effective registration statement
under the Securities Act of 1933, as amended, covering the offer and sale of
Common Stock in which (a) the public offering price equals or exceeds $4.00 per
share (adjusted to reflect subsequent stock dividends, stock splits or
recapitalization) and (b) the aggregate proceeds raised equals or exceeds
$10,000,000.

               Notwithstanding the foregoing, each share of Series A Preferred,
Series B Preferred and Series C Preferred shall automatically be converted into
shares of Common Stock at the applicable effective Conversion Rate upon the
approval (by vote or written consent, as provided by law) of the holders of at
least 2/3 of the then outstanding shares of Preferred Stock including the
holders of at least 2/3 of the then outstanding shares of Series C Preferred.

          (c)  Mechanics of Conversion.  Before any holder of the Preferred
               -----------------------
Stock shall be entitled to convert the same into shares of Common Stock, he
shall surrender the certificate or certificates therefor, duly endorsed, at the
office of the Corporation or of any transfer agent for the Preferred Stock and
shall give written notice to the Corporation at such office that he elects to
convert the same (except that no such written notice of election to convert
shall be necessary in the event of an automatic conversion pursuant to Section
3(b) hereof).  The Corporation shall, as soon as practicable thereafter, issue
and deliver at such office to such holder of Series A Preferred, Series B
Preferred or Series C Preferred a certificate or certificates for the number of
shares of Common

                                      -5-
<PAGE>

Stock to which such holder shall be entitled as aforesaid. Such conversion shall
be deemed to have been made immediately prior to the close of business on the
date of such surrender of the shares of Series A Preferred, Series B Preferred
or Series C Preferred to be converted (except that in the case of an automatic
conversion pursuant to Section 3(b) hereof such conversion shall be deemed to
have been made immediately prior to the closing of the offering referred to in
Section 3(b)) and the person or persons entitled to receive the shares of Common
Stock issuable upon such conversion shall be treated for all purposes as the
record holder or holders of such shares of Common Stock on such date.

          (d)  Fractional Shares.  In lieu of any fractional shares to which the
               -----------------
holder of Series A Preferred, Series B Preferred or Series C Preferred would
otherwise be entitled, the Corporation shall pay cash equal to such fraction
multiplied by the fair market value of one share of each such series of
Preferred Stock as determined by the Board of Directors of the Corporation.
Whether or not fractional shares are issuable upon such conversion shall be
determined on the basis of the total number of shares of Series A Preferred,
Series B Preferred or Series C Preferred of each holder to be converted at such
time into Common Stock and the number of shares of Common Stock issuable upon
such aggregate conversion.

          (e)  Adjustment of Conversion Price.  The applicable Conversion Price
               ------------------------------
of the Series A Preferred, Series B Preferred and Series C Preferred shall be
subject to adjustment from time to time as follows:

               (i)    If the Corporation shall issue any Common Stock other than
"Excluded Stock", as defined below, for a consideration per share less than the
applicable Conversion Price for such series in effect immediately prior to the
issuance of such Common Stock (excluding stock dividends, subdivisions, split-
ups, combinations, dividends or recapitalizations which are covered by Section
3(e)(iii), (iv), (v) and (vi)), the Conversion Price in effect for each such
series immediately after each such issuance shall forthwith (except as provided
in this Section 3(e)) be adjusted to a price equal to the quotient obtained by
dividing:

                      (1)  an amount equal to the sum of

                           (x)  the total number of shares of Common Stock
outstanding (including any shares of Common Stock issuable upon conversion of
the Series A Preferred, Series B Preferred and Series C Preferred, or deemed to
have been issued pursuant to subdivision (3) of this clause (i) and to clause
(ii) below) immediately prior to such issuance multiplied by the Conversion
Price in effect for each such series immediately prior to such issuance, plus

                           (y)  the consideration received by the Corporation
upon such issuance, by

                      (2)  the total number of shares of Common Stock
outstanding (including any shares of Common Stock issuable upon conversion of
the Series A Preferred, Series B

                                      -6-
<PAGE>

Preferred and Series C Preferred or deemed to have been issued pursuant to
subdivision (3) of this clause (i) and to clause (ii) below) immediately prior
to such issuance plus the additional shares of Common Stock issued in such
issuance (but not including any additional shares of Common Stock deemed to be
issued as a result of any adjustment in the Conversion Price resulting from such
issuance).

               For purposes of any adjustment of the Conversion Price pursuant
to this clause (i), the following provisions shall be applicable:

                      (1)  In the case of the issuance of Common Stock for cash,
the consideration shall be deemed to be the amount of cash paid therefor after
deducting any discounts or commissions paid or incurred by the Corporation in
connection with the issuance and sale thereof.

                      (2)  In the case of the issuance of Common Stock for a
consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair market value thereof as determined by the
Board of Directors of the Corporation, in accordance with generally accepted
accounting treatment; provided, however, that if, at the time of such
                      --------  -------
determination, the Corporation's Common Stock is traded in the over-the-counter
market or on a national or regional securities exchange, such fair market value
as determined by the board of directors of the Corporation shall not exceed the
aggregate "Current Market Price" (as defined below) of the shares of Common
Stock being issued.

                      (3)  In the case of the issuance of (i) options to
purchase or rights to subscribe for Common Stock (other than Excluded Stock),
(ii) securities by their terms convertible into or exchangeable for Common Stock
(other than Excluded Stock), or (iii) options to purchase or rights to subscribe
for such convertible or exchangeable securities:

                           (A)  the aggregate maximum number of shares of Common
Stock deliverable upon exercise of such options to purchase or rights to
subscribe for Common Stock shall be deemed to have been issued at the time such
options or rights were issued and for a consideration equal to the consideration
(determined in the manner provided in subdivisions (1) and (2) above), if any,
received by the Corporation upon the issuance of such options or rights plus the
minimum purchase price provided in such options or rights for the Common Stock
covered thereby;

                           (B)  the aggregate maximum number of shares of Common
Stock deliverable upon conversion of or in exchange for any such convertible or
exchangeable securities or upon the exercise of options to purchase or rights to
subscribe for such convertible or exchangeable securities and subsequent
conversion or exchange thereof, shall be deemed to have been issued at the time
such securities were issued or such options or rights were issued and for a
consideration equal to the consideration received by the Corporation for any
such securities and related options or rights (excluding any cash received on
account of accrued interest or accrued dividends), plus the minimum additional
consideration, if any, to be received by the Corporation

                                      -7-
<PAGE>

upon the conversion or exchange of such securities or the exercise of any
related options or rights (the consideration in each case to be determined in
the manner provided in subdivisions (1) and (2) above);

                           (C)  on any change in the number of shares of Common
Stock deliverable upon exercise of any such options or rights or conversion of
or exchange for such convertible or exchangeable securities, or on any change in
the minimum purchase price of such options, rights or securities, other than a
change resulting from the antidilution provisions of such options, rights or
securities, the Conversion Price shall forthwith be readjusted to such
Conversion Price as would have been obtained had the adjustment made upon (x)
the issuance of such options, rights or securities not exercised, converted or
exchanged prior to such change, as the case may be, been made upon the basis of
such change or (y) the options or rights related to such securities not
converted or exchanged prior to such change, as the case may be, been made upon
the basis of such change; and

                           (D)  on the expiration of any such options or rights,
the termination of any such rights to convert or exchange or the expiration of
any options or rights related to such convertible or exchangeable securities,
the Conversion Price shall forthwith be readjusted to such Conversion Price as
would have been obtained had the adjustment made upon the issuance of such
options, rights, convertible or exchangeable securities or options or rights
related to such convertible or exchangeable securities, as the case may be, been
made upon the basis of the issuance of only the number of shares of Common Stock
actually issued upon the exercise of such options or rights, upon the conversion
or exchange of such convertible or exchangeable securities or upon the exercise
of the options or rights related to such convertible or exchangeable securities,
as the case may be.

               (iii)  "Excluded Stock" shall mean:

                      (1)  all shares of Common Stock issued and outstanding on
the date this document is filed with the California Secretary of State and all
shares issuable upon exercise of options or warrants outstanding on the date
this document is filed with the California Secretary of State;

                      (2)  all shares of Series A Preferred, Series B Preferred
and Series C Preferred and the Common Stock into which the shares of Series A
Preferred, Series B Preferred and Series C Preferred are convertible; and

                      (3)  up to 1,461,429 shares of Common Stock, warrants or
options to purchase Common Stock or other securities issued to officers,
directors, consultants or employees of the Corporation pursuant to any plan or
arrangement approved by the Board of Directors of the Corporation.

                                      -8-
<PAGE>

                      (4)  shares of Common Stock, warrants or options to
purchase Common Stock or other securities issued to officers, directors,
consultants or employees of the Corporation pursuant to any plan or arrangement
approved by a 2/3 vote of the Board of Directors of the Corporation.

                      All outstanding shares of Excluded Stock (including any
shares issuable upon conversion of the Preferred Stock) shall be deemed to be
outstanding for all purposes of the computations of Section 3(e)(i) above.

               (iii)  If the number of shares of Common Stock outstanding at
any time after the date hereof is increased by a stock dividend payable in
shares of Common Stock or by a subdivision or split-up of shares of Common
Stock, then, on the date such payment is made or such change is effective, the
respective Conversion Prices of Series A Preferred, Series B Preferred and
Series C Preferred shall be appropriately decreased so that the number of shares
of Common Stock issuable on conversion of any shares of such series of Series A
Preferred, Series B Preferred and Series C Preferred shall be increased in
proportion to such increase of outstanding shares of Common Stock.

               (iv)   If the number of shares of Common Stock outstanding at
any time after the date hereof is decreased by a combination of the outstanding
shares of Common Stock, then, on the effective date of such combination, the
respective Conversion Prices of Series A Preferred, Series B Preferred and
Series C Preferred shall be appropriately increased so that the number of shares
of Common Stock issuable on conversion of any shares of a series of Series A
Preferred, Series B Preferred and Series C Preferred shall be decreased in
proportion to such decrease in outstanding shares of Common Stock.

               (v)    In case the Corporation shall declare a cash dividend
upon its Common Stock payable otherwise than out of retained earnings or shall
distribute to holders of its Common Stock shares of its capital stock (other
than Common Stock), stock or other securities of other persons, evidences of
indebtedness issued by the Corporation or other persons, assets (excluding cash
dividends) or options or rights (excluding options to purchase and rights to
subscribe for Common Stock or other securities of the Corporation convertible
into or exchangeable for Common Stock), then, in each such case, the holders of
shares of Series A Preferred, Series B Preferred and Series C Preferred shall,
concurrent with the distribution to holders of Common Stock, receive a like
distribution based upon the number of shares of Common Stock into which Series A
Preferred, Series B Preferred or Series C Preferred is convertible.

               (vi)   In case, at any time after the date hereof, of any
capital reorganization, or any reclassification of the stock of the Corporation
(other than as a result of a stock dividend or subdivision, split-up or
combination of shares), or the consolidation or merger of the Corporation with
or into another person (other than a consolidation or merger in which the
Corporation is the continuing entity and which does not result in any change in
the Common Stock), or of the sale or other disposition of all or substantially
all the properties and assets of the Corporation, the shares of

                                      -9-
<PAGE>

Series A Preferred, Series B Preferred and Series C Preferred shall, after such
reorganization, reclassification, consolidation, merger, sale or other
disposition, be convertible into the kind and number of shares of stock or other
securities or property of the Corporation or otherwise to which such holder
would have been entitled if immediately prior to such reorganization,
reclassification, consolidation, merger, sale or other disposition he had
converted his shares of Series A Preferred, Series B Preferred or Series C
Preferred into Common Stock. The provisions of this clause (vi) shall similarly
apply to successive reorganizations, reclassifications, consolidations, mergers,
sales or other dispositions.

               (vii)  All calculations under this Section 3 shall be made to
the nearest cent or to the nearest one hundredth (1/100) of a share, as the case
may be.

               (viii) For the purpose of any computation pursuant to this
Section 3(e), the "Current Market Price" at any date of one share of Common
Stock, shall be deemed to be the average of the highest reported bid and the
lowest reported offer prices on the preceding business day as furnished by the
National Quotation Bureau, Incorporated (or equivalent recognized source of
quotations); provided, however, that if the Common Stock is not traded in such
             --------  -------
manner that the quotations referred to in this clause (viii) are available for
the period required hereunder, Current Market Price shall be determined in good
faith by the Board of Directors of the Corporation, but if challenged by the
holders of more than 50% of the outstanding Series A Preferred, Series B
Preferred and Series C Preferred, voting as separate classes, then as determined
by an independent appraiser selected by the Board of Directors of the
Corporation, the cost of such appraisal to be borne equally by the Corporation
and the challenging parties.

          (f)  Minimal Adjustments. No adjustment in the Conversion Price need
               -------------------
be made if such adjustment would result in a change in the Conversion Price of
less than $0.01. Any adjustment of less than $0.01 which is not made shall be
carried forward and shall be made at the time of and together with any
subsequent adjustment which, on a cumulative basis, amounts to an adjustment of
$0.01 or more in the Conversion Price.

          (g)  No Impairment.  Without the consent of the majority of the
               -------------
outstanding shares of Preferred Stock, the Corporation will not through any
reorganization, recapitalization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms to be observed
or performed hereunder by the Corporation, but will at all times in good faith
assist in the carrying out of all the provisions of this Section 3 and in the
taking of all such action as may be necessary or appropriate in order to protect
the Conversion Rights of the holders of Series A Preferred, Series B Preferred
and Series C Preferred against impairment.

          (h)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Conversion Rate pursuant to this Section 3,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Preferred Stock a certificate setting forth such adjustment or

                                     -10-
<PAGE>

readjustment and showing in detail the facts upon which such adjustment or
readjustment is based.  The Corporation shall, upon written request at any time
of any holder of Series A Preferred, Series B Preferred or Series C Preferred,
furnish or cause to be furnished to such holder a like certificate setting forth
(i) such adjustments and readjustments, (ii) the Conversion Rate of such series
at the time in effect, and (iii) the number of shares of Common Stock and the
amount, if any, of other property which at the time would be received upon the
conversions of such holder's shares of Series A Preferred, Series B Preferred or
Series C Preferred.

          (i)  Notices of Record Date.  In the event of any taking by the
               ----------------------
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property or to receive any other right, the Corporation
shall mail to each holder of Series A Preferred, Series B Preferred and Series C
Preferred at least ten (10) days prior to such record date, a notice specifying
the date on which any such record is to be taken for the purpose of such
dividend or distribution or right, and the amount and character of such
dividend, distribution or right.

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

          (k)  Notices.  Any notice required by the provisions of this Section
               -------
3 to be given to the holder of shares of Series A Preferred, Series B Preferred
and Series C Preferred shall be deemed given if deposited in the United States
mail, postage prepaid, and addressed to each holder of record at his address
appearing on the books of the Corporation.

          (l)  Reissuance of Converted Shares.  No shares of Series A Preferred,
               ------------------------------
Series B Preferred and Series C Preferred which have been converted into Common
Stock after the original issuance thereof shall ever again be reissued and all
such shares so converted shall upon such conversion cease to be a part of the
authorized shares of the Corporation.

     4.   Voting Rights.  The holder of each share of Series A Preferred, Series
          -------------
B Preferred and Series C Preferred shall be entitled to the number of votes
equal to the number of shares of Common Stock into which each share of Series A
Preferred, Series B Preferred and Series C Preferred could be converted on the
record date for the vote or consent of shareholders written

                                     -11-
<PAGE>

consent and, except as otherwise required by law or provided for herein, shall
have voting rights and powers equal to the voting rights and powers of the
Common Stock. The holder of each share of Series A Preferred, Series B Preferred
and Series C Preferred shall be entitled to notice of any shareholders' meeting
in accordance with the bylaws of the Corporation and shall vote with holders of
the Common Stock upon the election of directors, except as provided in Section 5
herein, and upon any other matter submitted to a vote of shareholders, except
those matters required by law to be submitted to a class vote. Fractional votes
shall not, however, be permitted and any fractional voting rights resulting from
the above formula (after aggregating all shares of Common Stock into which
shares of Series A Preferred, Series B Preferred and Series C Preferred held by
each holder could be converted) shall be rounded to the nearest whole number
(with one-half rounded upward to one).

     5.   Election of Directors.  At each election of the Corporation's
          ---------------------
directors, (i) the holders of the Corporation's Series A Preferred shall have
the right, voting as a separate class (with cumulative voting rights as among
themselves in accordance with Section 708 of the California Corporations Code)
to elect one (1) member of the Board of Directors, (ii) the holders of the
Corporation's Series B Preferred shall have the right, voting as a separate

Board of Directors, (iii) the holders of the Corporation's Series C Preferred
shall have the right, voting as a separate class (with cumulative voting rights

Corporations Code) to elect two (2) members of the Board of Directors, and (iv)
the holders of the Corporation's Common Stock shall have the right, voting as a
separate class (with cumulative voting rights as among themselves in accordance
with Section 708 of the California Corporations Code) to elect two (2) members
of the Board of Directors.  Any additional directors shall be elected by all of
the holders of Common Stock and Preferred Stock, voting as a single class.

     6.   Protective Provisions.

                                     -12-
<PAGE>

               (iii) increase or decrease the aggregate number of authorized

Code;

               (iv)  create a new class or series of shares having rights,
preferences or privileges or increase the number of authorized shares of any
class or shares having rights, preferences or privileges equal to or senior to
any outstanding class or series;

               (v)   pay any dividend on or purchase, redeem or otherwise

law) of the holders of at least a majority of the then outstanding shares of
Series C Preferred:

               (i)   materially adversely change the rights, preferences,

or effect a reorganization with any other corporation (other than a wholly owned
subsidiary corporation) in which the shareholders of this Corporation
immediately prior to the transaction possess less than 50% of the voting power
of the surviving entity (or its parent) immediately after the transaction if the
consideration received by the holders of the Series C Preferred as a result of
any such liquidation, dissolution, merger or sale of all or substantially all of
the assets of the Corporation is less than $2.50 per share (as adjusted for any
stock dividends, combinations, splits, recapitalizations and the like with
respect to such shares)

                                     -13-

          (d)  Unless otherwise required by California law or except as provided
herein, the holders of Common Stock will not have the right to vote as a
separate class on any matter.

     7.   Repurchase of Shares.  In connection with repurchases by this
          --------------------
Corporation of its Common Stock, pursuant to its agreements with certain of the
holders thereof, Sections 502 and 503 of the California General Corporation Law
shall not apply in whole or in part with respect to such repurchases.

     8.   Series B Preferred - Right of Redemption.
          ----------------------------------------

          (a)  Subject to Section 8(e) herein, the Corporation shall be
obligated to redeem the Series B Preferred as follows:

               (i)  At any time after March 31, 2004, the holders of a
majority of the then outstanding shares of Series B Preferred (the "Series B
Initiating Holders") may require the Corporation to the extent it may lawfully
do so, to redeem all of the outstanding Series B Preferred in three (3) equal
annual installments with the first installment date being the date forty-five
(45) days after receipt by the Corporation of the Series B Exercise Notice (as
defined below), the second installment being the date one (1) year from the
first installment date and the last installment date being a date two (2) years
from such first installment date (each a "Series B Redemption Date").  The
Corporation shall effect such redemptions on the applicable Series B Redemption
Date by paying in cash in exchange for each share of Series B Preferred to be
redeemed on each applicable Series B Redemption Date a sum equal to the fair
market value per share of Series B Preferred as of the date of receipt by the
Corporation of the Series B Exercise Notice plus all accrued and unpaid
dividends thereon.  The fair market value per share of Series B Preferred for
the purposes of this Section 8, shall be determined by the Board of Directors of
the Corporation.  If such determination is unacceptable to the holders of a
majority of the Series B Preferred, then the fair market value per share of
Series B Preferred shall be determined by an investment banking firm mutually
acceptable to the Corporation and the holders of a majority of the Series B
Preferred.  The Series B Initiating Holders shall have the right to revoke a
Series B Exercise Notice by giving written notice to the Corporation within
fifteen (15) days after their receipt of the Series B Redemption Notice (as
defined below).  The total amount to be paid for the Series B Preferred is
hereinafter referred to as the "Series B Redemption Price." The number of shares
of Series B Preferred that the Corporation shall be required to redeem on any
one Series B Redemption Date shall be equal to the amount determined by dividing
(i) the aggregate number of shares of Series B Preferred outstanding immediately
prior to the Series B Redemption Date by (ii) the number of remaining Series B
Redemption Dates (including the Series B Redemption Date to which such
calculation applies).  Shares subject to redemption pursuant to this Section
8(a) shall be redeemed from each holder of Series B Preferred on a pro rata
basis.

               (ii) At any time after March 31, 2004, the Series B Initiating
Holders can elect to exercise the right of first redemption pursuant to this
Section 8(a) by providing written notice (the "Series B Exercise Notice") to the
Corporation. Within fifteen (15) days after the receipt

                                     -14-
<PAGE>

of the Series B Exercise Notice, the Corporation shall (i) send a notice (a
"Series B Redemption Notice") to each holder of record of the Series B Preferred
to be redeemed at the address of such holder appearing on the books of the
Corporation setting forth (a) the Series B Redemption Price for the shares to be
redeemed and (b) the place at which such holders may obtain payment of the
Series B Redemption Price upon surrender of their share certificates, and (ii)
send a notice to each holder of record of the Series C Preferred at the address
of such holder appearing on the books of the Corporation notifying such holders
of the election of the holders of the Series B Preferred to exercise the right
of redemption of the Series B Preferred. If the Corporation does not have
sufficient funds legally available to redeem all shares to be redeemed at any
Series B Redemption Date (including, if applicable, those to be redeemed at the
option of the Corporation), then it shall redeem such shares pro rata (based on
the portion of the aggregate Series B Redemption Price payable to them) to the
extent possible and shall redeem the remaining shares to be redeemed as soon as
sufficient funds are legally available.

          (b) On each Series B Redemption Date, the Corporation shall deposit
the portion of the Series B Redemption Price sufficient to redeem the shares to
be redeemed upon such Series B Redemption Date with a bank or trust corporation
having aggregate capital and surplus in excess of $100,000,000, as a trust fund,
with irrevocable instructions and authority to the bank or trust corporation to
pay, on and after such Series B Redemption Date, the applicable portion of the
Series B Redemption Price to their respective holders upon the surrender of
their share certificates.  Any monies deposited by the Corporation pursuant to
this Section 8(b) for the redemption of shares thereafter converted into shares
of Common Stock pursuant to Section 3 hereof no later than the fifth (5th) day
preceding the applicable Series B Redemption Date shall be returned to the
Corporation forthwith upon such conversion.  The balance of any funds deposited
by the Corporation pursuant to this Section 8(b) remaining unclaimed at the
expiration of one (1) year following such Series B Redemption Date shall be
returned to the Corporation.

          (c) On or after such Series B Redemption Date, each holder of shares
of Series B Preferred to be redeemed shall surrender such holder's certificates
representing such shares to the Corporation in the manner and at the place
designated in the Redemption Notice, and thereupon the applicable portion of the
Series B Redemption Price of such shares shall be payable to the order of the
person whose name appears on such certificate or certificates as the owner
thereof and each surrendered certificate shall be canceled. In the event less
than all the shares represented by such certificates are redeemed, a new
certificate shall be issued representing the unredeemed shares.  From and after
the date the Corporation deposits funds pursuant to Section 8(b) hereof with
respect to shares to be redeemed on such Series B Redemption Date, unless there
shall have been a default in payment of the applicable portion of the Series B
Redemption Price or the Corporation is unable to pay the applicable portion of
the Series B Redemption Price due to not having sufficient legally available
funds, all rights of the holders of such shares as holders of Series B Preferred
(except the right to receive the Series B Redemption Price without interest upon
surrender of their certificates), shall cease and terminate with respect to such
shares, provided that in the event that shares of Series B Preferred are not
redeemed due to a default in payment by the Corporation or because the

                                     -15-
<PAGE>

Corporation does not have sufficient legally available funds, such shares of
Series B Preferred shall remain outstanding and shall be entitled to all of the
rights and preferences provided herein.

          (d) In the event of a call for redemption of any shares of Series B
Preferred, the Conversion Rights (as defined in Section 3) for the shares of
Series B Preferred to be redeemed on a particular Series B Redemption Date shall
terminate at the close of business on the fifth (5th) day preceding such Series
B Redemption Date, unless default is made in payment of the Series B Redemption
Price.

          (e) In the event that the Series B Initiating Holders have elected to
exercise their right of redemption pursuant to this Section 8 and to the extent
that the Company receives the Series C Exercise Notice (as defined below) from
the Series C Initiating Holders (as defined below) prior to the deposit by the
Company of funds pursuant to Section 8(b) hereof with respect to any applicable
Series B Redemption Date, the right of redemption of the Series C Preferred
shall be superior and in preference to the right of redemption of the Series B
Preferred and the holders of the Series C Preferred shall be entitled to receive
the full amount of the Series C Redemption Price out of legally available funds
of the Corporation prior to the payment of any portion of the Series B
Redemption Price not previously deposited by the Company pursuant to Section
8(b) or required to be paid to the holders of the Series B Preferred pursuant to
the last sentence of Section 8(a)(ii) hereof. In such event, after the full
amount of the Series C Redemption Price has been deposited pursuant to Section
9(b) below, the holders of the Series B Preferred shall be entitled to receive
the full amount of the Series B Redemption Price of the Series B Preferred. If
the funds of the Corporation legally available for redemption of shares of the
Series C Preferred or Series B Preferred are insufficient to redeem the total
number of shares of Series C Preferred or Series B Preferred to be redeemed on a
Series B Redemption Date or Series C Redemption Date those funds which are
legally available will be used to redeem the maximum possible number of such
shares from first the holders of the Series C Preferred to the extent of the
full amount of the Series C Redemption Price and next to the holders of the
Series B Preferred to the extent of the full amount of the Series B Redemption
Price. The shares of Series C Preferred or Series B Preferred not redeemed, as
the case may be, shall remain outstanding and entitled to all the rights and
preferences provided herein, including the rights of conversion set forth in
Section 3. At any time thereafter when additional funds of the Corporation are
legally available for the redemption of shares of Series C Preferred or Series B
Preferred, as the case may be, such funds will immediately be used to redeem the
balance of the shares which the Corporation has become obliged to redeem on any
Redemption Date but which it has not redeemed.

     9.   Series C Preferred - Right of Redemption.
          ----------------------------------------

          (a)  Subject to Section 8(e) above, the Corporation shall be obligated
to redeem the Series C Preferred as follows:

               (i) Beginning on or after March 31, 2004, the holders of 66 2/3%
of the then outstanding shares of Series C Preferred (the "Series C Initiating
Holders") may require the

                                     -16-
<PAGE>

Corporation to the extent it may lawfully do so, to redeem all of the
outstanding Series C Preferred. Such redemption shall occur on the 45th day
following the Corporation's receipt of the Series C Exercise Notice (as defined
below) (such date being herein referred to as the "Initial Series C Redemption
Date"), provided that the Series C Initiating Holders shall have the right to
        --------
revoke a Series C Exercise Notice by giving written notice to the Corporation
within fifteen (15) days after their receipt of the Series C Redemption Notice,
and provided further that in lieu of redeeming all of the Series C Preferred on
    -------- -------
the Initial Series C Redemption Date the Corporation shall have the right to
redeem the Series C Preferred in three (3) equal installments, with the first
installment date being the Initial Series C Redemption Date, the second
installment being the first anniversary of the Initial Series C Redemption Date
and the last installment being the second anniversary of the Initial Series C
Redemption Date (the Initial Series C Redemption Date and each of such other
redemption dates being herein referred to as a "Series C Redemption Date"). The
Corporation shall effect such redemptions on the applicable Series C Redemption
Date by paying in cash in exchange for each share of Series C Preferred to be
redeemed on each applicable Series C Redemption Date, a sum equal to the fair
market value per share of Series C Preferred as of the date of receipt by the
Corporation of the Series C Exercise Notice plus all accrued and unpaid
dividends with respect to such shares thereon plus interest at the rate of 10%
per annum payable on the amount of the unpaid Series C Redemption Price (as
hereinafter defined) accruing from the Initial Series C Redemption Date until
paid. The fair market value per share of Series C Preferred for the purposes of
this Section 9, shall be determined by the Board of Directors of the
Corporation. If such determination is unacceptable to the holders of a majority
of the Series C Preferred, then the fair market value per share of Series C
Preferred shall be determined by an investment banking firm mutually acceptable
to the Corporation and the holders of a majority of the Series C Preferred. The
total amount to be paid for the Series C Preferred is hereinafter referred to as
the "Series C Redemption Price." The number of shares of Series C Preferred that
the Corporation shall be required to redeem on any one Series C Redemption Date
shall be equal to the amount determined by dividing (i) the aggregate number of
shares of Series C Preferred outstanding immediately prior to the Series C
Redemption Date by (ii) the number of remaining Series C Redemption Dates
(including the Series C Redemption Date to which such calculation applies).
Shares subject to redemption pursuant to this Section 9(a) shall be redeemed
from each holder of Series C Preferred on a pro rata basis.

          (ii) At any time after March 31, 2004, the Series C Initiating Holders
can elect to exercise the right of first redemption pursuant to this Section

to each holder of record of the Series C Preferred to be redeemed at the address
of such holder appearing on the books of the Corporation setting forth (a) the
Series C Redemption Price for the shares to be redeemed and (b) the place at
which such holders may obtain payment of the Series C Redemption Price upon
surrender of their share certificates. If the Corporation does not have

the portion of the aggregate

Series C Redemption Price payable to them) to the extent possible and shall
redeem the remaining shares to be redeemed as soon as sufficient funds are
legally available.

          (b) On or prior to the Series C Redemption Date, the Corporation shall
deposit the applicable portion of the Series C Redemption Price of the shares to
be redeemed on such Series C Redemption Date with a bank or trust corporation
having aggregate capital and surplus in excess of $100,000,000, as a trust fund,
with irrevocable instructions and authority to the bank or trust corporation to
pay, on and after such Series C Redemption Date, the applicable portion of the
Series C Redemption Price of the shares to their respective holders upon the
surrender of their share certificates. Any monies deposited by the Corporation
pursuant to this Section 9(b) for the redemption of shares thereafter converted
into shares of Common Stock pursuant to Section 3 hereof no later than the fifth
(5th) day preceding the Series C Redemption Date shall be returned to the
Corporation forthwith upon such conversion. The balance of any funds deposited
by the Corporation pursuant to this Section 9(b) remaining unclaimed at the
expiration of one (1) year following such Series C Redemption Date shall be
returned to the Corporation.

          (c) On or after such Series C Redemption Date, each holder of shares
of Series C Preferred to be redeemed shall surrender such holder's certificates
representing such shares to the Corporation in the manner and at the place
designated in the Series C Redemption Notice, and thereupon the applicable
portion of the Series C Redemption Price of such shares shall be payable to the
order of the person whose name appears on such certificate or certificates as
the owner thereof and each surrendered certificate shall be canceled. In the
event less than all the shares represented by such certificates are redeemed, a
new certificate shall be issued representing the unredeemed shares. From and
after the date the Corporation deposits funds pursuant to Section 9(b) hereof
with respect to shares to be redeemed on such Series C Redemption Date, unless
there shall have been a default in payment of the applicable portion of the
Series C Redemption Price or the Corporation is unable to pay the applicable
portion of the Series C Redemption Price due to not having sufficient legally
available funds, all rights of the holders of such shares as holders of Series C
Preferred (except the right to receive the Series C Redemption Price without
interest upon surrender of their certificates), shall cease and terminate with
respect to such shares, provided that in the event that shares of Series C
Preferred are not redeemed due to a default in payment by the Corporation or
because the Corporation does not have sufficient legally available funds, such
shares of Series C Preferred shall remain outstanding and shall be entitled to
all of the rights and preferences provided herein.

          (d) In the event of a call for redemption of any shares of Series C
Preferred, the Conversion Rights (as defined in Section 3) for the shares of
Series C Preferred to be redeemed on a particular Series C Redemption Date shall
terminate at the close of business on the fifth (5th) day preceding such Series
C Redemption Date, unless default is made in payment of the Series C Redemption

paid to me by the Company, I agree to the following:

     1.   At-Will Employment. I understand and acknowledge that my employment
          ------------------
with the Company is for an unspecified duration and constitutes "at-will"
employment. I acknowledge that this employment relationship may be terminated at
any time, with or without good cause or for any or no cause, at the option
either of the Company or myself, with or without notice.

     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 of the Company's 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 configuration information, marketing, finances
or other business information disclosed to me by the Company either directly or
indirectly in writing, orally or by drawings or observation of parts or
equipment. I further understand that Confidential Information does not include
any of the foregoing items which has become publicly known and 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
<PAGE>

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) Inventions Retained and Licensed. I have attached hereto, as
              --------------------------------
Exhibit A, a list describing 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 the 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.

          (b) 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"), except
as provided in Section 3(f) below. 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.

          (c) 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.

          (d) 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.

                                      -2-
<PAGE>

          (e) 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, 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.

          (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 which qualifies fully under the provisions of California Labor Code
Section 2870 (attached hereto as Exhibit B). I will advise the Company promptly
                                 ---------
in writing of any inventions that I believe meet the criteria in California
Labor Code Section 2870 and not otherwise disclosed on Exhibit A.
                                                       ---------

     (4)  Conflicting Employment. 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.

     (5)  Returning the 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 Certification" attached hereto as Exhibit
                                                                       -------

<PAGE>

     (6)  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 about my rights and obligations under this Agreement.

     (7)  Solicitation of Employees. I agree that for a period of twelve (12)
          -------------------------
months immediately following the termination of my relationship with the Company
for any reason, whether with or without cause, I shall not either directly or
indirectly solicit, induce, recruit or encourage any of the Company's employees
to leave their employment, or take away such employees, or attempt to solicit,
induce, recruit, encourage or take away employees of the Company, either for
myself or for any other person or entity.

     (8)  Conflict of Interest Guidelines.  I agree to diligently adhere to the
          -------------------------------
Conflict of Interest Guidelines attached as Exhibit D hereto.
                                            ---------

     (9)  Representations. I agree to execute any proper oath or verify any
          ---------------
proper document required to carry out the terms of this Agreement. I represent
that my performance of all the terms of this Agreement will not breach any
agreement to keep in confidence proprietary 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.

     (10) Arbitration and Equitable Relief.
          --------------------------------

          (a) Arbitration. Except as provided in Section 10(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 Francisco 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 of such Sections, 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.

     11.  General Provisions.
          ------------------

                                      -4-
<PAGE>

          (a)  Governing Law; Consent to Personal Jurisdiction. This Agreement
               -----------------------------------------------

consent to the personal jurisdiction of the state and federal courts located in
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 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.

          (c)  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.

          (d)  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.

                  EMPLOYMENT AGREEMENTS; ASSIGNMENT OF RIGHTS

     "(a) 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:

          (1)  Relate at the time of conception or reduction to practice of the

research or development of the employer.

          (2)  Result from any work performed by the employee for the employer.

                              INVENTA CORPORATION

                        CONFLICT OF INTEREST GUIDELINES

     It is the policy of 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 personnel actions affecting reward or
punishment of employees or applicants where there is a family relationship or is
or appears to be a personal or social involvement.

     5.   Initiating or approving any form of personal or social harassment of
employees.

     6.   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.

     7.   Borrowing from or lending to employees, customers or suppliers.

     8.   Acquiring real estate of interest to the Company.

     9.   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.
<PAGE>

     10.  Unlawfully discussing prices, costs, customers, sales or markets with
competing companies or their employees.

     11.  Making any unlawful agreement with distributors with respect to
prices.

     12.  Improperly using or authorizing the use of any inventions which are
the subject of patent claims of any other person or entity.


     13.  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.

                        RESTATED SHAREHOLDERS AGREEMENT



     THIS RESTATED SHAREHOLDERS AGREEMENT is made this 11th day of May, 1998,
between Inventa Corporation, a California corporation (the "Company"), the

          ---------
of the Company's Series A Preferred Stock (the "Series A Holders") listed on
Exhibit B attached hereto, the holders of the Company's Series B Preferred Stock
- ---------
(the "Series B Holders") listed on Exhibit C attached hereto, and certain
                                   ---------
holders of the Company's Common Stock (the "Common Holders") as listed on
Exhibit D attached hereto.  The Purchasers, Series A Holders and the Series B
- ---------
Holders shall collectively be referred to as the "Preferred Holders".  The
Purchasers, the Founder, the Preferred Holders and the Common Holders shall
collectively be referred to as the "Shareholders".

     WHEREAS, Founder is the beneficial owner or may be deemed to be the
beneficial owner of 4,500,000 shares of the Common Stock of the Company.

     WHEREAS, the Series A Holders and the Company are parties to the Series A
Preferred Stock Purchase Agreement dated July 8, 1994 (the "Series A
Agreement").

     WHEREAS, the Series B Holders and the Company are parties to the Series B
Preferred Stock Purchase Agreement dated February 14, 1997 (the "Series B
Agreement").

     WHEREAS, the Common Holders are the owners of 42,696 shares of the Common
Stock of the Company.

     WHEREAS, the parties desire that this Agreement supersede the Shareholders
Rights Agreement dated February 14, 1997 in its entirety.

     WHEREAS, the Purchasers have requested, as a condition to entering into the

Agreement, and the Founder and the Shareholders, as an inducement to the
Purchasers to enter into the Series C Agreement of even date herewith, are
willing to enter into this Agreement.

     NOW, THEREFORE, in consideration of the premises, mutual covenants and
terms hereof, the receipt and sufficiency of which is hereby acknowledged, the
parties agree as follows:
<PAGE>

                                   ARTICLE I

                Right of First Refusal on Shareholder Transfer
                ----------------------------------------------

     1.1  Company Right.  If at any time a Shareholder desires (or is required)
          -------------
to sell or transfer in any manner any Shares (as hereinafter defined) pursuant
to the terms of a bona fide offer received from a third party (a "Buyer"), the
Shareholder shall submit a written offer to sell such Shares (the "Offered
Shares") to the Company on terms and conditions, including price, not less
favorable to the Company than those on which the Shareholder proposes to sell
such Offered Shares to Buyer (the "Offer"). The Offer shall disclose the
identity of the Buyer, the number of Offered Shares, the terms of the proposed
sale or transfer and any other material facts relating to the sale or transfer.
Within fifteen (15) days after receipt of the Offer, the Company shall give
notice to the Shareholder of its intent to purchase all or some of the Offered
Shares from the Shareholder on the terms and conditions set forth in the Offer.

     1.2  Preferred Holders' Right.  If, for any reason whatsoever, the Company
          ------------------------
shall not exercise its right to purchase all of the Offered Shares as provided
herein, the Company shall promptly provide to the Preferred Holders, written
notice (the "Notice") of same (which shall include a copy of the Offer provided
to the Company pursuant to Section 1.1 hereof), and then the Preferred Holders
shall have the right, for a period of fifteen (15) days from the date of the
Notice to purchase, on a pro rata basis, on the same terms and conditions as are
set forth in the Offer, that portion of the Offered Shares which the Company
shall not have agreed to purchase from the Shareholder (all such remaining
Shares being referred to as the "Remaining Offered Shares"). For purposes of
this Section 1.2, Preferred Holder's pro rata right shall be calculated by
dividing the number of shares of Common Stock issuable upon conversion of
Preferred Stock held by such Preferred Holder by the total number of shares of
Common Stock issuable upon conversion of Preferred Stock held by all Preferred
Holders.

     1.3  Failure to Exercise Rights.  In the event that the Company and the
          --------------------------
Preferred Holders, taken together, do not purchase all of the Offered Shares
pursuant to and within the time periods set forth above, any remaining Offered
Shares may be sold or transferred by the Shareholder at any time within 90 days
thereafter, subject to compliance with Article II.  Any such sale or transfer
shall be at not less than the price nor upon other terms and conditions, if any,
not more favorable to the Buyer than those specified in the Offer.  Any Offered
Shares not sold within such 90-day period shall thereafter again be subject to
the requirements of this Article I.  In the event that Shares are sold or
transferred to the Preferred Holders pursuant to this subsection, said Offered
Shares shall no longer be subject to this Agreement.

     1.4  Price.  With respect to any Shares to be transferred pursuant to
          -----
Section 1.1 hereof and as to which a price has not been set by the Shareholder
under Section 1.1 hereof, the price per Share shall be a price set by the Board
of Directors of the Company which will reflect the current value of the Shares
in terms of present earnings and future prospects of the Company.  The Company
shall notify the Shareholder of the price so determined within fifteen (15) days
after receipt by it of the Offer.  If the Shareholder disputes the price as set
by the Board of Directors by giving notice to the Company within ten (10) days
after being informed of the price, the price of the Shares shall be determined
by an

                                      -2-
<PAGE>

independent financial analyst selected by the Board of Directors of the Company,
with the cost of such determination to be divided equally between the Company
and the Shareholder. The Board of Directors shall select such analyst within
fifteen (15) days after receipt of notice that the Shareholder is disputing the
price set by the Board of Directors. If the Board is not notified of any such
dispute within such ten (10) day period, the decision of the Board of Directors
as to the purchase price shall be final. Any time required to determine a
purchase price or to resolve a dispute shall be added to the fifteen (15) day
period in which the Company may exercise its right to purchase the Offered
Shares.

     1.5  Transfer of Rights.  The right of the Preferred Holders to purchase
          ------------------
Offered Shares hereunder may not be assigned except to a transferee or assignee
who qualifies as a partner, subsidiary or affiliate of one of the Preferred
Holders, or a parent of one of the Preferred Holders, or any entity which has
the same parent corporation as one of the Preferred Holders.

     1.6  Prohibited Transfers.  The Shareholder shall not sell, assign,
          --------------------
transfer, pledge, hypothecate, mortgage or dispose of, by gift or otherwise, or
in any way encumber, all or any part of the Shares owned by him during the term
of this Agreement other than in compliance with the terms of this Article I.

     1.7  Definition of "Shares".  For purposes of this Article I, the term
          ----------------------
"Shares" shall mean and include all shares of capital stock of the Company owned
by the Shareholder, whether presently held or hereafter acquired.

     1.8  Permitted Transfers.  The right of first refusal contained in this
          -------------------
Article I shall not apply to: (a) any transfer of Shares by the Shareholder by
gift or bequest or through inheritance to, or for the benefit of, any family
member; (b) any transfer of Shares by the Shareholder to a trust for the benefit
of any family member; (c) any sale or transfer of Shares to the Company (or any
assignee of the Company) pursuant to the terms of a stock restriction or stock
repurchase agreement (which provides for such sale upon the Shareholder's
termination of employment); (d) any sale of Common Stock in a public offering
pursuant to a registration statement filed by the Company with the Securities
and Exchange Commission; (e) any pledge made pursuant to a bona fide loan
transaction that creates a mere security interest; or (f) any transfer of Shares
by the Shareholder that is a partnership to its partners. In the event of any
transfer pursuant to (a), (b) or (f), the transferee of the Shares shall hold
the Shares so acquired with all the rights conferred by, and subject to all the
restrictions imposed by, this Agreement.

                                  ARTICLE II

                    Right of Co-Sale on Shareholder Transfer
                    ----------------------------------------

     2.1  Right of Co-Sale.  In the event that the Shareholder desires (or is
          ----------------
required) to sell or transfer in any manner any Shares (as hereinafter defined)
pursuant to the terms of a bona fide offer received from a Buyer, and the
Company and the Preferred Holders do not exercise their right of first refusal
as to all of the Offered Shares as set forth in Article I hereof, each Preferred
Holder shall have the right (the "Right of Co-Sale") to require, as a condition
to such sale or transfer, that the Buyer purchase from each Preferred Holder at
the same price per share and on the same terms and conditions as involved in
such sale or disposition by the Shareholder that percentage of the Offered
Shares not

                                      -3-
<PAGE>

purchased by the Company or the Preferred Holders pursuant to Article I above,
expressed by a fraction, the numerator of which is the number of shares of
Preferred Stock (on an as-converted into Common Stock basis) and Common Stock
held by such Preferred Holder and the denominator of which is the aggregate
number of shares of Preferred Stock (on an as-converted into Common Stock basis)
and Common Stock held by all Preferred Holders and the number of Shares held by
the Shareholder. The Preferred Holders shall act upon the Buyer's offer to buy
as soon as practicable after receipt from the Company of the Notice and in all
events within fifteen (15) days after receipt of the Notice. In the event that
the Preferred Holders shall elect to exercise their Right of Co-Sale, the
Preferred Holders shall communicate in writing such election to the Shareholder.

     2.2  Agreement not to Transfer.  The Shareholder shall not sell, assign,
          -------------------------

owned by him during the term of this Agreement other than in compliance with the
terms of this Article II.

     2.3  Definition of Shares.  For purposes of this Article II, the term
          --------------------
"Shares" shall mean and include all shares of capital stock of the Company owned
by the Shareholder, whether presently held or hereafter acquired.

     2.4  Permitted Transfers.  The Right of Co-Sale contained in this Article
          -------------------
II shall not apply to: (a) any transfer of Shares by the Shareholder by gift or
bequest or through inheritance to, or for the benefit of, any family member; (b)
any transfer of Shares by the Shareholder to a trust for the benefit of any
family member; (c) any sale or transfer of Shares to the Company pursuant to the
terms of a stock restriction or stock repurchase agreement (which provides for
such sale upon the Shareholder's termination of employment with the Company, if
applicable); (d) any sale or transfer of Shares to the Company or the Preferred
Holders pursuant to the provisions of Article I hereof; (e) any sale of Common
Stock in a public offering pursuant to a registration statement filed by the
Company with the Securities and Exchange Commission; (f) any pledge made
pursuant to a bona fide loan transaction that creates a mere securities
interest; or (g) any transfer of Shares by the Shareholder that is a partnership
to its partners. In the event of any transfer pursuant to (a), (b) or (f) the
transferee of the Shares shall hold the Shares so acquired with all the rights
conferred by, and subject to all the restrictions imposed by, this Agreement.

     2.5  Prohibited Transfers.
          --------------------

          (a)  In the event that the Shareholder should sell any Shares in
contravention of the co-sale rights of each Preferred Holder under this
Agreement (a "Prohibited Transfer"), each Preferred Holder, in addition to such
other remedies as may be available at law, in equity or hereunder, shall have
the put option provided below, and such Shareholder shall be bound by the
applicable provisions of such option.

          (b)  In the event of a Prohibited Transfer, each Preferred Holder
shall have the right to sell to such Shareholder the type and number of shares
of Common Stock equal to the number of shares each Preferred Holder would have
been entitled to transfer to the Buyer under Section 2.1 hereof

                                      -4-
<PAGE>

had the Prohibited Transfer been effected pursuant to and in compliance with the
terms hereof. Such sale shall be made on the following terms and conditions:

               (i)    The price per share at which the shares are to be sold to
the Shareholder shall be equal to the price per share paid by the Buyer to such
Shareholder in such Prohibited Transfer. The Shareholder shall also reimburse
each Preferred Holder for any and all fees and expenses, including legal fees
and expenses, incurred pursuant to the exercise or the attempted exercise of the
Preferred Holder's rights under this Article II.

               (ii)   Within ninety (90) days after the date on which a
Preferred Holder received notice of the Prohibited Transfer or otherwise became
aware of the Prohibited Transfer, such Preferred Holder shall, if exercising the
option created hereby, deliver to the Shareholder the certificate or
certificates representing the shares to be sold, each certificate to be properly
endorsed for transfer.

               (iii)  Such Shareholder shall, upon receipt of the certificate or
certificates for the shares to be sold by a Preferred Holder, pursuant to this
Section 2.5(b), pay the aggregate purchase price therefor and the amount of
reimbursable fees and expenses, as specified in Section 2.5(b)(i), in cash or by
other means acceptable to the Preferred Holder.

               (iv)   Notwithstanding the foregoing, any attempt by the
Shareholder to transfer Shares in violation of Article II hereof shall be
voidable at the option of a majority in interest of the Preferred Holders if the
Preferred Holders do not elect to exercise the put option set forth in this
Section 2.5, and the Company agrees it will not effect such a transfer nor will
it treat any alleged transferee as the holder of such shares without the written
consent of a majority in interest of the Preferred Holders.

                                  ARTICLE III

                  Right of First Refusal on Company Issuances
                  -------------------------------------------

     3.1  Grant of Right to Purchasers.  Except as set forth in Article IV, the
          ----------------------------
Company hereby grants to each of the Purchasers who continue to hold shares of
Series C Preferred Stock purchased pursuant to the Series C Agreement, the right
of first refusal to purchase, on a pro rata basis based on the number of shares
of Common Stock issuable upon conversion of shares of Series C Preferred Stock
then held by them, in the aggregate, fifty (50) percent of the New Securities
(as defined in Section 3.3) which the Company may, from time to time propose to
sell and issue. The Purchasers may purchase said New Securities on the same
terms and at the same price at which the Company proposes to sell the New
Securities. The right of first refusal granted pursuant to this Section 3.1
shall terminate upon the closing of the first sale of the next series or several
series of Preferred Stock of the Company authorized by the shareholders of the
Company subsequent to the date hereof with aggregate proceeds to the Company
from the sale of the next series or several series of Preferred Stock of at
least $5,000,000.

     3.2  Grant of Right.  Except as set forth in Article IV, the Company hereby
          --------------
grants to each Preferred Holder who continues to hold, respectively, shares of
Series A Preferred Stock purchased

                                      -5-
<PAGE>

pursuant to the Series A Agreement, Series B Preferred Stock purchased pursuant
to the Series B Agreement and Series C Preferred Stock purchased pursuant to the
Series C Agreement (the "Preferred Shares"), the right of first refusal to
purchase all or any part of such Preferred Holder's Pro Rata Share (as
hereinafter defined) of the New Securities (as defined in Section 3.3) which the
Company may, from time to time, propose to sell and issue, with a right of over-
subscription (as provided in Section 3.4 below); provided, however, that with
respect to the Purchasers, the right of first refusal pursuant to this Section
3.2 shall only commence after the termination of the Purchasers' right of first
refusal pursuant to Section 3.1 above. The Preferred Holders may purchase said
New Securities on the same terms and at the same price at which the Company
proposes to sell the New Securities. The "Pro Rata Share" of each Preferred
Holder, for purposes of this right of first refusal, is the ratio of the total
number of shares of Common Stock held by such Preferred Holder, including (i)
any shares of Common Stock into which shares of Preferred Stock held by such
Preferred Holder are convertible, and (ii) any shares deliverable upon the
exercise of options of other rights to purchase Common Stock held by such
Preferred Holder, to the total number of shares of Common Stock outstanding
immediately prior to the issuance of the New Securities (including (i) any
shares of Common Stock into which outstanding shares of Preferred Stock are
convertible and (ii) any shares deliverable upon the exercise of options or
other rights to purchase Common Stock).

     3.3  New Securities.  "New Securities" shall mean any capital stock of the
          --------------
Company, whether now authorized or not, and any rights, options or warrants to
purchase said capital stock, and securities of any type whatsoever that are, or
may become, convertible into said capital stock; provided, however, that "New
                                                 --------  -------
Securities" does not include (i) the Preferred Shares or other securities issued
or issuable upon conversion of the Preferred Shares ("Conversion Shares"), (ii)
securities offered pursuant to a registration statement filed under the
Securities Act of 1933, as amended (the "Act"),  (iii) securities issued
pursuant to the acquisition of another corporation by the Company by merger,
purchase of substantially all of the assets or other reorganization, (iv) shares
offered pursuant to lease financing transactions or bank or lending institution
financing transactions that are approved by the Board of Directors, (v)
securities issued in connection with any stock split, stock dividend or
recapitalization of the Company, (vi) all securities hereafter issued or
issuable to officers, directors, employees or consultants of the Company (for
the primary purpose of soliciting or retaining their employment or services)
pursuant to any employee or consultant stock offering, plan or arrangement
approved by the Board of Directors, and (vii) securities issuable pursuant to
warrants outstanding as of May 11, 1998 (the "Warrant Shares") or securities
issued upon conversion of the Warrant Shares.

     3.3  Notice.  In the event the Company proposes to undertake an issuance
          ------
of New Securities, it shall give to the Preferred Holders written notice (the
"Company Notice") of its intention, describing the type of New Securities,
number of shares, the price, the terms upon which the Company proposes to issue
the same, and notice to the effect that each Preferred Holder must respond to
such Company Notice within twenty (20) days after the date thereof. The
Preferred Holders shall have twenty (20) days from the date of such Company
Notice to purchase any or all of the New Securities for the price and upon the
terms specified in the Company Notice by giving written notice to the Company
and stating therein the quantity of New Securities to be purchased and
forwarding payment for such New Securities to the Company if immediate payment
is required by such terms, or in any event no later than forty-five (45) days
after the date of the Company Notice. The Company shall promptly, in writing,
inform each

                                      -6-
<PAGE>

Preferred Holder which elects to purchase its Pro Rata Share of the New
Securities of any other Preferred Holder's failure to do so (the "Over-
subscription Notice"), in which case the Preferred Holders electing to purchase
their Pro Rata Share of the New Securities shall have the right to purchase
their Pro Rata Share of such shares (the "Over-subscription Right") and any
portion of the remainder of such shares which other Preferred Holders have
elected not to purchase pursuant to the exercise of their Over-subscription
Right, for the price and upon the terms specified in the Company Notice for a
period of thirty (30) days after the date of the Over-subscription Notice. If a
Preferred Holder elects not to exercise such right, then that portion of the
shares which is not purchased may be offered to third parties on terms no less
favorable to the Company for a period of one hundred twenty (120) days.

     3.5  Sale after Company Notice.  In the event any Preferred Holder fails to
          -------------------------
exercise in full the right of first refusal within said twenty (20) day period,
the Company shall have ninety (90) days thereafter to sell or enter into an
agreement (pursuant to which the sale of New Securities covered thereby shall be
closed, if at all, within thirty (30) days from the date of said agreement) to
sell the New Securities respecting which such Preferred Holder's rights were not
exercised, at a price and upon general terms no more favorable to the Preferred
Holders thereof than specified in the Company Notice. In the event the Company
has not sold the New Securities within said ninety (90) day period (or sold and
issued New Securities in accordance with the foregoing within thirty (30) days
from the date of said agreement), the Company shall not thereafter issue or sell
any New Securities without first offering such securities to the Preferred
Holders in the manner provided above.

     3.6  Assignment.  The right of first refusal granted under this Article III
          ----------
is assignable by the Preferred Holders to any transferee of a minimum of fifty
thousand (50,000) shares of Series A Preferred Stock (as adjusted for any stock
split, stock dividends, combinations, recapitalizations and the like with
respect to such shares) or fifty thousand (50,000) shares of Series B Preferred
Stock (as adjusted for any stock split, stock dividends, combinations,
recapitalizations and the like with respect to such shares), or fifty thousand
(50,000) shares of Series C Preferred Stock (as adjusted for any stock split,
stock dividends, combinations, recapitalizations and the like with respect to
such shares), as applicable, or the Common Stock into which each such series of
Preferred Stock has been converted. For the purposes of satisfying the 50,000
share threshold herein, the number of shares of the Common Stock issuable upon
conversion of applicable series of Preferred Stock owned by the Preferred
Holders shall include the holdings of partners, subsidiaries, parents,
shareholders or affiliates of the Preferred Holders (or any entities which have
the same parent corporation as the Preferred Holders) and such holdings shall be
aggregated together and with the holdings of the Preferred Holders with respect
to the applicable series of Preferred Stock.

provisions of the Securities Act or, in the case of Section 16 hereof, to assist
in an orderly distribution. Each Shareholder will cause any proposed transferee
of

                                       2
<PAGE>

Restricted Securities held by that Shareholder to agree to take and hold those
securities subject to the provisions and upon the conditions specified in this
Agreement.

     3.   Restrictive Legend.  Each certificate representing (i) the Shares,
          ------------------
and (ii) shares of the Company's Common Stock issued upon conversion of the
Shares, and (iii) any other securities issued in respect of the Shares, or the
Common Stock issued upon conversion of the Shares, upon any stock split, stock
dividend, recapitalization, merger, consolidation or similar event, shall
(unless otherwise permitted or unless the securities evidenced by such
certificate shall have been registered under the Securities Act) be stamped or
otherwise imprinted with a legend substantially in the following form (in
addition to any legend required under applicable state securities laws):

          THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
          INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933, AS AMENDED, (THE "ACT") OR ANY STATE SECURITIES LAWS.  SUCH
          SHARES MAY NOT BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF SUCH
          REGISTRATION OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND
          ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE ACT.
          COPIES OF THE AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND
          RESTRICTING THEIR TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN
          REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE
          SECRETARY OF THE CORPORATION AT THE PRINCIPAL EXECUTIVE OFFICE OF THE
          CORPORATION.

          Upon request of a holder of such a certificate, the Company shall
remove the foregoing legend from the certificate or issue to such holder a new
certificate therefor free of any transfer legend, if, with such request, the
Company shall have received either the opinion referred to in Section 4(i) or
the "no-action" letter referred to in Section 4(ii) to the effect that any
transfer by such holder of the securities evidenced by such certificate will not
violate the Securities Act and applicable state securities laws, unless any such
transfer legend may be removed pursuant to Rule 144(k), in which case no such
opinion or "no-action" letter shall be required, and provided that the Company
shall not be obligated to remove any such legends prior to the date of the
initial public offering of the Company's Common Stock under the Securities Act.

     4.   Notice of Proposed Transfers.  The holder of each certificate
          ----------------------------
representing Restricted Securities by acceptance thereof agrees to comply in all
respects with the provisions of this Section 4. Prior to any proposed transfer
of any Restricted Securities (other than under circumstances described in
Sections 5, 6 and 8 hereof), the holder thereof shall give written notice to the
Company of such holder's intention to effect such transfer.  Each such notice
shall describe the manner and circumstances of the proposed transfer in
sufficient detail, and shall be accompanied (except in transactions in
compliance with Rule 144 promulgated under the Securities Act or for a transfer
to a holder's spouse, ancestors, descendants or a trust for any of their
benefit, or in transactions involving the distribution without consideration of
Restricted Securities by a holder to any of its partners or

                                       3
<PAGE>

retired partners or to the estate of any of its partners or retired partners) by
either (i) a written opinion of legal counsel to the holder who shall be
reasonably satisfactory to the Company, addressed to the Company and reasonably
satisfactory in form and substance to the Company's counsel, to the effect that
the proposed transfer of the Restricted Securities may be effected without
registration under the Securities Act or (ii) a "no-action" letter from the
Commission to the effect that the distribution of such securities without
registration will not result in a recommendation by the staff of the Commission
that action be taken with respect thereto, whereupon the holder of such
Restricted Securities shall be entitled to transfer such Restricted Securities
in accordance with the terms of the notice delivered by such holder to the
Company. Each certificate evidencing the Restricted Securities transferred as
above provided shall bear the restrictive legend set forth in Section 3 above,
except that such certificate shall not bear such restrictive legend after the
date of the Company's initial public offering under the Securities Act if the
opinion of counsel or "no-action" letter referred to above expressly indicates
that such legend is not required in order to establish compliance with the
Securities Act or if such legend is no longer required pursuant to Rule 144(k).

     5.   Demand Registration.
          -------------------

          (a)  Request for Registration.  If the Company shall receive from
               ------------------------
Initiating Holders a written request that the Company effect any registration
with respect to the Registrable Securities, the Company will:

               (i)  promptly given written notice of the proposed registration
          to all other Holders; and

               (ii) as soon as practicable, use its diligent best efforts to
          effect such registration after January 1, 2000 (including, without
          limitation, the execution of an undertaking to file post effective
          amendments, appropriate qualification under applicable blue sky or
          other state securities laws and appropriate compliance with applicable
          regulations issued under the Securities Act) as may be so requested
          and as would permit or facilitate the sale and distribution of all or
          such portion of such Registrable Securities as are specified in such
          request, together with all or such portion of the Registrable
          Securities of any Holder or Holders joining in such request as are
          specified in a written request delivered to the Company within fifteen
          (15) days after receipt of such written notice from the Company;
          provided that the Company shall not be obligated to effect, or to take
          any action to effect, any such registration pursuant to this Section
          5:

                    (A)  In any particular jurisdiction in which the Company
          would be required to execute a general consent to service of process
          in effecting such registration, qualification or compliance, unless
          the Company is already subject to service in such jurisdiction and
          except as may be required by the Securities Act;

                    (B)  After the Company has effected two (2) such
          registrations pursuant to this Section 5(a) and such registrations
          have been declared or ordered effective, or

                                       4
<PAGE>

          withdrawn at the request of the majority of the Initiating Holders,
          and the sales of such Registrable Securities have closed; or

                    (C)  Within one hundred eighty (180) days of the effective
          date of any other registration statement on Form S-1.

          Subject to the foregoing clauses (A), (B) and (C), the Company shall
file a registration statement covering the Registrable Securities so requested
to be registered as soon as practicable, after receipt of the request or
requests of the Initiating Holders; provided, however, that if the Company shall
furnish to such Holders a certificate signed by the President of the Company
stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company and its shareholders
for such registration statement to be filed on or before the time filing would
be required and it is therefore essential to defer the filing of such
registration statement, the Company shall have the right to defer such filing
(but not more than once during any twelve month period) for a period of not more
than ninety (90) days after receipt of the request of the Initiating Holders.

          The registration statement filed pursuant to the request of the
Initiating Holders, may, subject to the provisions of Section 5(b) below,
include other securities of the Company which are held by officers or directors
of the Company or which are held by persons who, by virtue of agreements with
the Company, are entitled to include their securities in any such registration,
but the Company shall have no right to include any of its securities in any such
registration except as provided in Section 5(b) below.

          (b)  Underwriting.  If the Initiating Holders intend to distribute the
               ------------
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
Section 5, and the Company shall include such information in the written notice
referred to in Section 5(a)(i) above. The right of any Holder to registration
pursuant to Section 5 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting (unless otherwise mutually agreed by a majority-in-interest of
the Initiating Holders and such Holder with respect to such participation and
inclusion) to the extent provided herein. A Holder may elect to include in such
underwriting all or a part of the Registrable Securities he holds.

          If officers or directors of the Company shall request inclusion of
securities of the Company other than Registrable Securities in any registration
pursuant to Section 5, or if holders of securities of the Company who are
entitled by contract with the Company to have securities included in such a
registration (such officers, directors, and other shareholders being
collectively referred to as the "Other Shareholders") request such inclusion,
the Initiating Holders shall, on behalf of all Holders, offer to include the
securities of such Other Shareholders in the underwriting and may condition such
offer on their acceptance of the further applicable provisions of this
Agreement.  The Company shall (together with all Holders and Other Shareholders
proposing to distribute their securities through such underwriting) enter into
an underwriting agreement in customary form with

                                       5
<PAGE>

the representative of the underwriter or underwriters (the "Underwriter")
selected for such underwriting by more than fifty percent (50%) of the
Initiating Holders and reasonably acceptable to the Company. Notwithstanding any
other provision of this Section 5, if the Underwriter determines that marketing
factors require a limitation on the number of shares to be underwritten, the
Underwriter may (subject to the allocation priority set forth below) limit the
number of Registrable Securities to be included in the registration and
underwriting to not less than fifty percent (50%) of the securities which
Holders have requested be included therein. The Company shall so advise all
holders of securities requesting registration, and the number of shares of
securities that are entitled to be included in the registration and underwriting
shall be allocated in the following priority: first, among all Holders of
Registrable Securities requesting inclusion (and pro rata among such holders on
the basis of all Registrable Securities then held by such holders); and second,
among all Other Shareholders in proportion, as nearly as practicable, to the
respective amounts of securities which they had requested to be included in such
registration at the time of filing the registration statement. If any Holder or
Other Shareholder disapproves of the terms of any such underwriting, such holder
may elect to withdraw therefrom by written notice to the Company and the
Underwriter. Any Registrable Securities excluded or withdrawn from such
underwriting shall be withdrawn from such registration. If the Underwriter has
not limited the number of Registrable Securities or other securities to be
underwritten, the Company may include its securities for its own account in such
registration if the underwriter so agrees and if the number of Registrable
Securities and other securities which would otherwise have been included in such
registration and underwriting will not thereby be limited.

     6.   Company Registration.
          --------------------

          (a)  If the Company shall determine to register any of its securities
either for its own account or for the account of a security holder or holders
exercising their respective demand registration rights, other than a
registration relating solely to employee benefit plans or a registration
relating solely to a Commission Rule 145 transaction or a registration on any
registration form which does not permit secondary sales or does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of Registrable Securities, the Company
will:

               (i)  promptly give to each Holder written notice thereof (which,
          to the extent then known, shall include a list of the jurisdictions in
          which the Company intends to attempt to qualify such securities under
          the applicable blue sky or other state securities laws); and

               (ii) include in such registration (and any related qualification
          under blue sky laws or other compliance), and in any underwriting
          involved therein, all of the Registrable Securities specified in a
          written request or requests made by any Holder within fifteen (15)
          days after receipt of the written notice from the Company described in
          clause (i) above, except as set forth in Section 6(b) below. Such
          written request may specify all or a part of a Holder's Registrable
          Securities.

                                       6
<PAGE>

          (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 a part of the written notice given
pursuant to Section 6(a)(i). In such event the right of any Holder to
registration pursuant to Section 6 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of such Holder's
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 Shareholders distributing their
securities through such underwriting) enter into an underwriting agreement in
customary form with the Underwriter selected for underwriting by the Company.
Notwithstanding any other provision of this Section 6, if the Underwriter
determines that marketing factors require a limitation on the number of shares
to be underwritten, and (a) if such registration is the first registered
offering of the Company's securities to the public, the Underwriter may (subject
to the allocation priority set forth below) exclude from such registration and
underwriting some or all of the Registrable Securities which would otherwise be
underwritten pursuant hereto, and (b) if such registration is other than the
first registered offering of the sale of the Company's securities to the public,
the Underwriter may (subject to the allocation priority set forth below) limit
the number of Registrable Securities to be included in the secondary portion of
the registration and underwriting to not less than fifty percent (50%) of the
securities which Holders have requested be included therein. The Company shall
so advise all holders of securities requesting registration, and the number of
shares of securities that are entitled to be included in the registration and
underwriting by persons other than the Company shall be allocated in the
following priority: first, to Holders of Registrable Securities (and pro rata
among such holders on the basis of all Registrable Securities then held by such
holders); and second, among all Other Shareholders in proportion, as nearly as
practicable, to the respective amounts of securities which they had requested to
be included in such registration at the time of filing the registration
statement. If any Holder or Other Shareholder disapproves of the terms of any
such underwriting, he may elect to withdraw therefrom by written notice to the
Company and the Underwriter. Any Registrable Securities or other securities
excluded or withdrawn from such underwriting shall be withdrawn from such
registration.

     7.   Expenses of Registration.  All Registration Expenses incurred in
          ------------------------
connection with any registration, qualification or compliance pursuant to this
Agreement shall be borne by the Company, and all Selling Expenses shall be borne
by the holders of the securities so registered pro rata on the basis of the
number of their shares so registered; provided, however, that the Company shall
not be required to pay any Registration Expenses if, as a result of the
withdrawal of a request for registration by Initiating Holders, the registration
statement does not become effective, unless such withdrawal is caused by a
material adverse change in the business or operations of the Company after such
request for registration, or unless the Initiating Holders agree to have such
registration considered a registration pursuant to Section 5(a)(ii)(B).  If the
Company is not required to pay any Registration Expenses, then the Holders and
Other Shareholders requesting registration shall bear such Registration Expenses
pro rata on the basis of the number of their shares so included in the
registration request, and such registration shall not be considered a
registration for purposes of Section 5(a)(ii)(B).

                                       7
<PAGE>

     8.   Registration on Form S-3.  The Company shall use its best efforts to
          ------------------------
qualify for registration on Form S-3, and to that end, the Company shall comply
with the reporting requirements of the Exchange Act following the effective date
of the first registration of any securities of the Company for a registered
public offering. After the Company has qualified for the use of Form S-3,
Initiating Holders shall have the right to request four (4) registrations on
Form S-3 (such requests shall be in writing and shall state the number of shares
of Registrable Securities to be disposed of and the intended method of
disposition of such shares by each such holder), subject only to the following
limitations:

          (a)  The Company shall not be obligated to cause a registration on
Form S-3 to become effective prior to one hundred eighty (180) days following
the effective date of a Company-initiated registration (other than a
registration effected solely to qualify an employee benefit plan or to effect a
business combination pursuant to Rule 145), provided that notice of such
Company-initiated registration is given to Holders prior to receipt of a request
from a holder of Registrable Securities for registration on Form S-3, and
provided that the Company shall use its best efforts to achieve such
effectiveness promptly following such one hundred eighty (180) day period;

          (b)  The Company shall not be obligated to cause a registration on
Form S-3 to become effective prior to expiration of one hundred eighty (180)
days following the effective date of the most recent registration pursuant to a
request by a holder of Registrable Securities under this Agreement or pursuant
to a request by a holder of registration rights under any other agreement of the
Company granting Form S-3 demand registration rights; provided, however, that
the Company shall use its best efforts to achieve such effectiveness promptly
following such one hundred eighty (180) day period;

          (c)  The Company shall not be required to effect a registration
pursuant to this Section 8 more than once in any twelve (12) month period;

          (d)  The Company shall not be required to maintain and keep any such
registration on Form S-3 effective for a period exceeding one hundred eighty
(180) days from the effective date thereof.  The Company shall give notice to
all Holders and all holders of registration rights under any other agreement of
the Company granting Form S-3 or similar demand registration rights of the
receipt of a request for registration pursuant to this Section 8 and shall
provide a reasonable opportunity for all such other holders to participate in
the registration.  Subject to the foregoing, the Company will use its best
efforts to effect promptly the registration of all shares of Registrable
Securities on Form S-3 to the extent requested by the Holder or Holders thereof
for purposes of disposition.  In the event the Underwriter, in the case of an
underwritten offering, determines that market factors require a limitation on
the number of shares to be underwritten, then shares shall be excluded from such
registration and underwriting pursuant to the method described in Section 6(b);
and

          (e)  The value of the aggregate shares of Registrable Securities to be
registered on Form S-3 for each such right of registration shall be at least
$500,000.

                                       8
<PAGE>

     9.   Registration Procedures.  In the case of each registration effected by
          -----------------------
the Company pursuant to this Agreement, the Company will keep each Holder
advised in writing as to the initiation of such registration and as to the
completion thereof. At its expense, the Company will:

          (a)  Keep such registration effective for a period of ninety (90) days
or until the Holder or Holders have completed the distribution described in the
registration statement relating thereto, whichever first occurs; and

          (b)  Furnish such number of prospectuses and other documents incident
thereto as a Holder from time to time may reasonably request; and

          (c)  In connection with any underwritten offering pursuant to a
registration statement filed pursuant to Section 5 or 8 hereof, the Company will
enter into any underwriting agreement reasonably necessary to effect the offer
and sale of Common Stock, provided such underwriting agreement contains
customary underwriting provisions, and provided further that if the underwriter
so requests the underwriting agreement will contain customary indemnification
and contribution provisions, and provided further that the Underwriter is
reasonably acceptable to the Company.

     10.  Indemnification.
          ---------------

          (a)  The Company will indemnify each Holder, each of its officers,
directors and partners, and each person controlling such Holder, if Registrable
Securities held by such Holder are included in the securities with respect to
which registration, qualification or compliance has been effected pursuant to
this Agreement, and each underwriter, if any, and each person who controls any
underwriter, against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any prospectus, offering
circular or other document (including any related registration statement,
notification or the like) incident to any such registration, qualification or
compliance, or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading,
or any violation by the Company of the Securities Act including any rule or
regulation thereunder applicable to the Company relating to action or inaction
required of the Company in connection with any such registration, qualification
or compliance, and will reimburse each such Holder, each of its officers,
directors and partners, and each person controlling such Holder, each such
underwriter and each person who controls any such underwriter, for any legal and
any other expenses reasonably incurred in connection with investigating and
defending any such claim, loss, damage, liability or action, provided that the
Company will not be liable in any such case to the extent that any such claim,
loss, damage, liability or expense arises out of or is based on any untrue
statement (or alleged untrue statement) or omission (or alleged omission) based
upon written information furnished to the Company by such Holder or underwriter
and stated to be specifically for use therein.

                                       9
<PAGE>

          (b)  Each Holder will, if Registrable Securities or other securities
held by such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, indemnify the
Company, each of its directors, officers and agents and each underwriter, if
any, of the Company's securities covered by such a registration statement, each
person who controls the Company or such underwriter within the meaning of the
Securities Act and the rules and regulations thereunder, each other such Holder
and each of their officers, directors and partners, and each person controlling
such Holder, against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances in
which they were made, not misleading, and will reimburse the Company and such
Holders, directors, officers, agents, partners, persons, underwriters or control
persons for any legal or any other expenses reasonably incurred in connection
with investigating of defending any such claim, loss, damage, liability or
action, in each case to the extent, but only to the extent, that such untrue
statement (or alleged untrue statement) or omission (or alleged omission) is
made in such registration statement, prospectus, offering circular or other
document in reliance upon and in conformity with written information furnished
to the Company by such Holder and stated to be specifically for use therein;
provided, however, that the obligations of such Holders hereunder shall be
limited to an amount equal to the net proceeds to each such Holder of securities
sold as contemplated herein.

          (c)  Each party entitled to indemnification under this Section 10 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or any litigation resulting
therefrom, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Agreement.  An indemnified
party shall have the right to retain its own 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.  No
Indemnifying Party in the defense of any such claim or litigation shall, except
with the consent of each Indemnified Party, consent to entry of any judgment or
enter into any settlement which does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such Indemnified Party of a
release from all liability in respect to such claim or litigation.  Each
Indemnified Party shall furnish such information regarding itself or the claim
in question as an Indemnifying Party may reasonably request in writing and as
shall be reasonably required in connection with defense of such claim and
litigation resulting therefrom.

                                      10
<PAGE>

          (d)  If the indemnification provided for in this Section 10 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the extent permitted by applicable law contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability 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 any untrue or alleged untrue statement of a material fact or
the omission to state a material fact that resulted in such loss, claim, damage
or liability, as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by a court of law 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;
provided, that in no event shall any contribution by a Holder thereunder exceed
the proceeds from the offering received by such Holder.

          (e)  The obligations of the Company and Holders under this Section 10
shall survive completion of any offering of Registrable Securities in a
registration statement and the termination of this agreement.

     11.  Information by Holder.  Each Holder holding securities included in any
          ---------------------
registration shall furnish to the Company such information regarding such Holder
as the Company may reasonably request in writing and as shall be reasonably
required in connection with any registration, qualification or compliance
referred to in this Agreement.

     12.  Limitations on Registration of Issues of Securities.  From and after
          ---------------------------------------------------
the date of this Agreement, the Company shall not enter into any agreement with
any holder or prospective holder of any securities of the Company giving such
holder or prospective holder the right to require the Company to initiate any
registration of any securities of the Company, provided that this Section 12
shall not limit the right of the Company to enter any agreements with any holder
or prospective holder of any securities of the Company giving such holder or
prospective holder the right to require the Company, upon any registration of
any of its securities, to include, among the securities which the Company is
then registering, securities owned by such holder. Any right given by the
Company to any holder or prospective holder of the Company's securities in
connection with the registration of securities shall be conditioned such that it
shall be consistent with the provisions of this Agreement and with the rights of
the Holders provided in this Agreement.

     13.  Rule 144 Reporting.  With a view to making available the benefits of
          ------------------
certain rules and regulations of the Commission which may permit the sale of the
Restricted Securities to the public without registration, the Company agrees to:

          (a)  Make and keep public information available as those terms are
understood and defined in Rule 144 under the Securities Act, at all times from
and after ninety (90) days following

                                      11
<PAGE>

the effective date of the first registration under the Securities Act filed by
the Company for an offering of its securities to the general public;

          (b)  Use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act at any time after it has become subject to
such reporting requirements;

          (c)  So long as a Shareholder owns any Restricted Securities, furnish
to the Shareholder forthwith upon request a written statement by the Company as
to its compliance with the reporting requirements of Rule 144 (at any time from
and after ninety (90) days following the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents so filed as a Shareholder may reasonably request in availing itself of
any rule or regulation of the Commission allowing a Shareholder to sell any such
securities without registration.

     14.  No-Action Letter or Opinion of Counsel in Lieu of Registration.
          --------------------------------------------------------------
Notwithstanding anything in this Agreement to the contrary, if at any time after
the date of the Company's initial public offering of its securities under the
Securities Act the Company shall have obtained from the Commission a "no-action"
letter in which the Commission has indicated that it will take no action if,
without registration under the Securities Act, any Holder disposes of
Registrable Securities covered by any request for registration made under this
Agreement in the manner in which such Holder proposes to dispose of the
Registrable Securities included in such request, or if in the opinion of counsel
for the Company concurred in by counsel for such Holder no registration under
the Securities Act is required in connection with such disposition, the
Registrable Securities included in such request shall not be eligible for
registration under this Agreement; provided, however, with respect to any Holder
who may deemed to be an "affiliate," as that term is defined under Rule 144, if,
notwithstanding the opinion of such counsel, the Holder is unable to dispose of
all of the Registrable Securities included in his request in the manner in which
such Holder so proposes without registration, the Registrable Securities
included in such request shall be eligible for registration under this
Agreement.

     15.  Transfer or Assignment of Registration Rights.  The rights to cause
          ---------------------------------------------
the Company to register Shareholder's securities granted to Shareholder by the
Company under Sections 5, 6 and 8 hereof may be transferred or assigned by
Shareholder to a transferee or assignee of at least 100,000 shares of the
Restricted Securities; provided, however, that a Shareholder may transfer or
assign such rights to a partner or shareholder of Shareholder without
restriction as to minimum shareholding. The Company shall be given written
notice by Shareholder at the time of said transfer or assignment, stating the
name and address of said transferee or assignee and identifying the securities
with respect to which such registration rights are being transferred or
assigned, and provided further that the transferee or assignee of such rights is
not deemed by the Board of Directors of the Company, in its

                                      12
<PAGE>

reasonable judgment, to be a competitor of the Company; and provided further
that the transferee or assignee of such rights assumes the obligations of a
Shareholder under this Agreement.

     16.  "Market Stand-off" Agreement.  Each Shareholder agrees, if requested
          ----------------------------
by the Company and an underwriter of Common Stock (or other securities) of the
Company, not to sell or otherwise transfer or dispose of any Common Stock (or
other securities) of the Company held by Shareholder during a period of time
determined by the Company and its underwriters (not to exceed 180 days)
following the effective date of the Company's initial public offering of its
capital stock, provided that all officers, directors and employees of the
Company holding stock or stock options of at least one (1%) percent of the
Company's outstanding stock prior to the initial public offering of the Company
enter into similar agreements; provided, further, that with respect to the
Series C Holders, the prohibition against the sale, transfer or other
dispostions of any Common Stock (or other securities) of the Company held by
them pursuant to this Section 16 shall not prohibit (i) the sale of any shares
of Common Stock purchased by such Series C Holder pursuant to a directed share
program or otherwise in the Company's initial public offering, or (ii) the sale,
in the open market, of any shares of Common Stock by such Series C Holder
provided that such shares are purchased in the open market after the completion
of the Company's initial public offering.

          Such agreement shall be in writing in a form satisfactory to the
Company and such underwriter.  The Company may impose stop-transfer instructions
with respect to the Shares (or securities) subject to the foregoing restriction
until the end of said period.

     17.  Governing Law.  This Agreement and the legal relations between the
          -------------
parties arising hereunder shall be governed by and interpreted in accordance
with the laws of the State of California. The parties hereto agree to submit to
the jurisdiction of the federal and state courts of the State of California with
respect to the breach or interpretation of this Agreement or the enforcement of
any and all rights, duties, liabilities, obligations, powers, and other
relations between the parties arising under this Agreement.

     18.  Entire Agreement.  This Agreement constitutes the full and entire
          ----------------
understanding and agreement between the parties regarding rights to
registration.  Except as otherwise expressly provided herein, the provisions
hereof shall inure to the benefit of, and be binding upon, the successors,
assigns, heirs, executors and administrators of the parties hereto.

     19.  Notices, Etc.  All notices and other communications required or
          -------------
permitted hereunder shall be in writing and shall be mailed by first-class mail,
postage prepaid, or otherwise delivered by hand or by messenger, addressed (a)
if to a Shareholder, at the address or addresses set forth on Exhibit A,
                                                              ---------
Exhibit B or Exhibit C attached hereto, or at such other address or addresses as
- ---------    ---------
the Shareholder shall have furnished to the other parties hereto in writing, or
(b) if to any other holder of any securities, at such address as such holder
shall have furnished the other parties hereto in writing, or, until any such
holder so furnishes an address to the Company, then to and at the address of the
last holder of such Shares who has so furnished an address to the Company, or
(c) if to the Company,

                                      13
<PAGE>

at the address of its principal offices set forth on the signature page of this
Agreement, or at such other address as the Company shall have furnished to the
other parties hereto in writing.

     20.  Other Registration Rights.  This Agreement supersedes any previous
          -------------------------
agreement between the Company and any party with respect to the grant by the
Company of registration rights, including but not limited to Registration Rights
Agreement dated February 14, 1997.

     21.  Counterparts.  This Agreement may be executed in any number of
          ------------
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

     22.  Amendments.  Any provision of this Agreement may be amended, waived or
          ----------
modified upon the written consent of the Company, and the Shareholders (or their
assignees to whom Shareholders have expressly assigned their rights in
compliance with Section 15 hereof) who then hold more than fifty percent (50%)
of the Registrable Securities then held by persons entitled to registration
rights hereunder, provided further, any such amendment, waiver or modification
applies by its terms to each applicable Shareholder and each such assignee and,
provided further, that a Shareholder or such assignee hereunder may waive any of
such Holder's rights or the Company's obligations hereunder without obtaining
the consent of any other Shareholder or assignee.

               [LETTERHEAD OF WILSON SONSINI GOODRICH & ROSATI]



                                  May 11, 1998



To:  Each Investor listed on
     the Schedule of Investors
     to the Inventa Corporation
     Series C Convertible Preferred
     Stock Purchase Agreement

Ladies and Gentlemen:

     Reference is made to the Series C Convertible Preferred Stock Purchase
Agreement dated as of May 11, 1998 (the "Agreement"), complete with all listed
exhibits thereto, by and among Inventa Corporation, a California corporation,
(the "Company") and each of you, providing for the issuance by the Company to
the Investors of shares of Series C Preferred Stock of the Company (the
"Shares"). This opinion is rendered to you in compliance with Section 5.8 of the
Agreement, and all terms used herein have the meanings defined for them in the
Agreement unless otherwise defined herein.

     We have acted as counsel for the Company in connection with the negotiation
of the Agreement and the issuance of the Shares.  As such counsel, we have made
such legal and factual examinations and inquiries as we have deemed advisable or
necessary for the purpose of rendering this opinion.  In addition, we have
examined originals or copies of such corporate records of the Company,
certificates of public officials and such other documents which we consider
necessary or advisable for the purpose of rendering this opinion.  In such
examination we have assumed the genuineness of all signatures on original
documents, the authenticity and completeness of all documents submitted to us as
originals, the conformity to original documents of all copies submitted to us
and the due execution and delivery of all documents (except as to due execution
and delivery by the Company) where due execution and delivery are a prerequisite
to the effectiveness thereof.

     As used in this opinion, the expression "to our knowledge," "known to us"
or similar language with reference to matters of fact means that, after an
examination of documents made available to us by the Company, and after
inquiries of officers of the Company, but without any further independent
factual investigation, we find no reason to believe that the opinions expressed
herein are factually incorrect.  Further, the expression "to our knowledge,"
"known to us" or similar language with reference to matters of fact refers to
the current actual knowledge of the attorneys of this firm who have worked on
matters for the Company.  Except to the extent expressly set forth herein or as
we otherwise believe to be necessary to our opinion, we have not undertaken any
independent investigation to determine the existence or absence of any fact, and
no inference as to our knowledge
<PAGE>

of the existence or absence of any fact should be drawn from our representation
of the Company or the rendering of the opinion set forth below.

     For purposes of this opinion, we are assuming that you have all requisite
power and authority, and have taken any and all necessary corporate or
partnership action, to execute and deliver the Agreement, and we are assuming
that the representations and warranties made by the Investors in the Agreement
and pursuant thereto are true and correct.  We are also assuming that each
Investor has purchased the Shares for value, in good faith and without notice of
any adverse claims within the meaning of the California Uniform Commercial Code.

     The opinions hereinafter expressed are subject to the following
qualifications:

          (a) We express no opinion as to the effect of applicable bankruptcy,
insolvency, reorganization, moratorium or other similar federal or state laws
affecting the rights of creditors;

          (b) We express no opinion as to the effect of rules of law governing
specific performance, injunctive relief or other equitable remedies (regardless
of whether any such remedy is considered in a proceeding at law or in equity);

          (c) We express no opinion as to compliance with the anti-fraud
provisions of applicable securities laws;

          (d) We express no opinion as to the enforceability of the
indemnification provisions of the Registration Rights Agreement, to the extent
the provisions thereof may be subject to limitations of public policy and the
effect of applicable statutes and judicial decisions; and

          (e) We are members of the Bar of the State of California and we
express no opinion as to any matter relating to the laws of any jurisdiction
other than the federal laws of the United States of America and the laws of the
State of California.  To the extent this opinion addresses applicable securities
laws of states other than the State of California, we have not retained nor
relied on the opinion of counsel admitted to the bar of such states, but rather
have relied on compilations of the securities laws of such states contained in
reporting services presently available to us.

     Based upon and subject to the foregoing, and except as set forth in the
Schedule of Exceptions to the Agreement, we are of the opinion that:

     1.   The Company is a corporation duly organized and validly existing
under, and by virtue of, the laws of the State of California and is in good
standing under such laws.  The Company has requisite corporate power to own and
operate its properties and assets, and to carry on its business as presently
conducted.  The Company is duly qualified to do business, and in good standing
in all foreign jurisdictions where its ownership or leasing of properties or the
conduct of its business requires such qualification, except where the failure to
be so qualified would not have a material adverse effect on the Company's
business as now conducted.

                                       2
<PAGE>

     2.   The Company has all requisite legal and corporate power to execute and
deliver the Agreement, the Shareholder Agreement  and the Registration Rights
Agreement, to sell and issue the Shares under the Agreement, to issue the Common
Stock issuable upon conversion of the Shares and to carry out and perform its
obligations under the terms of the Agreement, the Shareholders Agreement, and
the Registration Rights Agreement.

     3.   The authorized capital of the Company consists of (i) 8,119,511 shares
of Preferred Stock, 1,000,000 shares of which are designated Series A Preferred
Stock and of which 800,000 are issued and outstanding, and 2,560,000 shares of
which are designated Series B Preferred and of which 2,560,000 are issued and
outstanding, and 4,059,511 shares of which are designated Series C Preferred
Stock and of which none are issued and outstanding, and (ii) 25,000,000 shares
of Common Stock, of which 4,642,344 shares are issued and outstanding.  All
issued and outstanding shares of the Company's capital stock have been duly
authorized and validly issued and are fully paid and nonassessable.  The Shares,
when issued pursuant to the terms of the Agreement (including Common Stock
issued upon conversion of the Shares), will be duly authorized, validly issued,
fully paid and nonassessable.  Except as set forth in the Agreement, the
Shareholders Agreement, and the Registration Rights Agreement and all the
exhibits thereto, to out knowledge, there are no options, warrants or other
rights (including conversion or preemptive rights) or agreements outstanding to
purchase any of the Company's authorized and unissued capital stock.

     4.   All corporate action on the part of the Company, its directors and
shareholders necessary for the authorization, execution, delivery and
performance of the Agreement, the Shareholders Agreement and the Registration
Rights Agreement, the authorization, sale, issuance and delivery of the Shares
and the performance of the Company's obligations under the Agreement, the
Shareholders Agreement, and the Registration Rights Agreement has been taken.
The Agreement, the Shareholders Agreement, and the Registration Rights Agreement
have been duly and validly executed and delivered by the Company and constitute
valid and binding obligations of the Company, enforceable against the Company in
accordance with their terms.  The Shares will have the rights, preferences and
privileges described in the Restated Articles.  To our knowledge, the Shares and
the Common Stock issuable on conversion of the Shares will be free of any liens,
encumbrances or preemptive rights contained in the Company's Restated Articles
or Bylaws.

     5.   The execution, delivery and performance of and compliance with the
terms of the Agreement, and the issuance of the Shares do not violate any
provision of the Restated Articles or Bylaws, or, to our knowledge, any
provisions of any applicable federal or state law, rule or regulation.  To our
knowledge, the execution, delivery and performance of and compliance with the
Agreement, the Shareholders Agreement, and the Registration Rights Agreement and
the issuance of the Shares do not violate or constitute a default under, any
material contract, agreement, instrument, judgment or decree binding upon the
Company.

     6.   To our knowledge, there are no actions, suits, proceedings or
investigations pending against the Company or its properties before any court or
governmental agency (nor, to our knowledge, has the Company received any written
threat thereof), which, either in any case or in the

                                       3
<PAGE>

aggregate, are likely to result in any material adverse change in the business
or financial condition of the Company, or in any material impairment of the
right or ability of the Company to carry on its business as now conducted, or
which questions the validity of the Agreement, the Shareholders Agreement or the
Registration Rights Agreement or any action taken or to be taken by the Company
in connection therewith.

     7.   No consent, approval or authorization of or designation, declaration
or filing with any governmental authority on the part of the Company is required
in connection with the valid execution and delivery of the Agreement, the
Shareholders Agreement, and the Registration Rights Agreement or other offer,
sale or issuance of the Shares or the consummation of any other transaction
contemplated thereby, except (a) filing of the Restated Articles in the Office
of the Secretary of State of the State of California, and (b) qualification (or
taking such action as may be necessary to secure an exemption from
qualification, if available) under the California Corporate Securities Law and
other applicable blue sky laws (but excluding jurisdictions outside of the
United States) of the offer and sale of the Shares (and the Common Stock
issuable upon conversion thereof) and the modification of rights of shareholders
contemplated by the Agreement.  The filing referred to in clause (a) above has
been accomplished and is effective, and to our knowledge there are no
proceedings or written threat thereof which question the validity of such
filing.  Our opinion herein is otherwise subject to the timely and proper
completion of all filings and other actions contemplated by clause (b) above
where such filings and actions are to be undertaken on or after the date hereof.

     8.   Subject to the accuracy of each Investor's representations in Section
3 of the Agreement we are of the opinion that the offer, sale and issuance of
the Shares in conformity with the terms of the Agreement constitute transactions
exempt from the registration requirements of Section 5 of the Securities Act of
1933, as amended.

     This opinion is furnished to the Investors solely for their benefit in
connection with the purchase of the Shares, and may not be relied upon by any
other person or for any other purpose without our prior written consent.


                              Very truly yours,

                              WILSON SONSINI GOODRICH & ROSATI

                          MANAGEMENT RIGHTS AGREEMENT

     This MANAGEMENT RIGHTS AGREEMENT ("Agreement") is entered into as of May
11, 1998 by and between Inventa Corporation, a California corporation (the
"Company") and TCV II (Q), L.P., a Delaware limited partnership ("Fund").


                                   RECITALS

     A.   Fund's organizational documents require that Fund have and maintain
the status of a "venture capital operating company" as defined in the Department
of Labor Regulations, Section 25101.3-101(d) (the "Regulations").

     B.   The Regulations require that a venture capital operating company
must have direct contractual rights to participate substantially in or
substantially influence the conduct of the management of its portfolio
companies.

     C.   In order to induce Fund to invest in the Company, the Company has
agreed to provide such rights to Fund.

     NOW THEREFORE, the parties hereto agree that upon Fund's purchase of shares
of Series C Preferred Stock of the Company, Fund will be entitled to the
following contractual management rights, in addition to rights to non-public
financial information, inspection rights, and other rights specifically provided
to all investors in connection with the current financing:

     (1)  Fund shall be entitled to consult with and advise management of the
Company on significant business issues, including management's proposed annual
and quarterly operating plans, and management will meet with Fund within thirty
days after the end of each fiscal quarter at the Company's facilities at
mutually agreeable times for such consultation and advice and to review progress
in achieving said plans;

     (2)  Fund may examine the books and records of the Company and inspect
its facilities and may request information at reasonable times and intervals
concerning the general status of the Company's financial condition and
operations, provided that access to highly confidential proprietary information
and facilities need not be provided except to the extent provided to all of the
Company's investors under the terms of the current financing;

     (3)  If Fund is not represented on the Company's Board of Directors by
an affiliate of the Fund, the Company shall invite a representative of Fund to
attend all meetings of its Board of Directors in a nonvoting observer capacity
(provided that such representative may be excluded from such portion of the
meetings of the Board of Directors as (i) is an executive session of the Board
of Directors limited solely to Board members, (ii) necessary to protect the
attorney-client privilege or (iii) would result in a conflict of interest with
Fund) and, in this respect, shall give such representative timely copies of all
notices, minutes, consents, and other material that it provides to its
directors. Such representative may participate in discussions of matters brought
to the Board.

     Fund agrees, and will cause any representative of Fund to agree, to hold in
confidence and trust and not use or disclose any confidential information
provided to or learned by it in connection with its rights under this Agreement.
<PAGE>

     The rights described herein shall terminate and be of no further force or
effect upon the consummation of the sale of the Company's securities pursuant to
a registration statement filed by the Company under the Securities Act of 1933,
as amended, in connection with the firm commitment underwritten offering of its
securities to the public. The confidentiality provisions hereof will survive any
such termination.

     IN WITNESS WHEREOF the parties hereto have hereby executed this Agreement
as of the date first above written.

         This MANAGEMENT RIGHTS AGREEMENT ("Agreement") is entered into as of
May 11, 1998 by and between Inventa Corporation, a California corporation (the
"Company") and Technology Crossover Ventures II, L.P., a Delaware limited

                                   RECITALS

         A.  Fund's organizational documents require that Fund have and maintain
the status of a "venture capital operating company" as defined in the Department
of Labor Regulations, Section 25101.3-101(d) (the "Regulations").

         B.  The Regulations require that a venture capital operating company
must have direct contractual rights to participate substantially in or
substantially influence the conduct of the management of its portfolio
companies.

         C.  In order to induce Fund to invest in the Company, the Company has
agreed to provide such rights to Fund.

         NOW THEREFORE, the parties hereto agree that upon Fund's purchase of
shares of Series C Preferred Stock of the Company, Fund will be entitled to the
following contractual management rights, in addition to rights to non-public
financial information, inspection rights, and other rights specifically provided
to all investors in connection with the current financing:

         (1) Fund shall be entitled to consult with and advise management of the
Company on significant business issues, including management's proposed annual
and quarterly operating plans, and management will meet with Fund within thirty
days after the end of each fiscal quarter at the Company's facilities at
mutually agreeable times for such consultation and advice and to review progress
in achieving said plans;

         (2) Fund may examine the books and records of the Company and inspect
its facilities and may request information at reasonable times and intervals
concerning the general status of the Company's financial condition and
operations, provided that access to highly confidential proprietary information
and facilities need not be provided except to the extent provided to all of the
Company's investors under the terms of the current financing;

         (3) If Fund is not represented on the Company's Board of Directors by
an affiliate of the Fund, the Company shall invite a representative of Fund to
attend all meetings of its Board of Directors in a nonvoting observer capacity
(provided that such representative may be excluded from such portion of the
meetings of the Board of Directors as (i) is an executive session of the Board
of Directors limited solely to Board members, (ii) necessary to protect the
attorney-client privilege or (iii) would result in a conflict of interest with
Fund) and, in this respect, shall give such representative timely copies of all
notices, minutes, consents, and other material that it provides to its
directors. Such representative may participate in discussions of matters brought
to the Board.

         Fund agrees, and will cause any representative of Fund to agree, to

          of Series A Preferred Stock, 2,560,000 shares of Series B Preferred
          Stock, 8,055,511 shares of Series C Preferred Stock and 4,755,194
          shares of Common Stock. The number of shares voting in favor of the

                                  ----------

                AMENDED AND RESTATED ARTICLES OF INCORPORATION

                                      OF

                              INVENTA CORPORATION

                                      I.

     The name of this corporation is Inventa Corporation (the "Corporation").

                                      II.

     The purpose of this Corporation is to engage in any lawful act or activity
for which a corporation may be organized under the General Corporation Law of
California other than the banking business, the trust company business or the
practice of a profession permitted to be incorporated by the California
Corporations Code.

                                     III.

     This Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock." The total number
of shares which the Corporation is authorized to issue is 39,779,511 shares, of
which 25,000,000 shares shall be Common Stock with a par value of $0.001 per
share and of which 14,779,511 shares shall be Preferred Stock, 1,000,000 of
which are designated Series A Preferred Stock with a par value of $0.001 per
share, 2,560,000 of which are designated Series B Preferred Stock with a par
value of $0.001 per share, 8,219,511 of which are designated Series C Preferred
Stock with a par value of $0.001 per share and 3,000,000 of which are designated
Series D Preferred Stock with a par value of $0.001 per share. The Board of
Directors is authorized to fix the number of shares of any series of Preferred
Stock and to determine or alter the rights, preferences, privileges, and
restrictions granted to or imposed upon any wholly unissued series of Preferred
Stock and, within the limits and restrictions stated in any resolution or
resolutions of the Board of Directors originally fixing the number of shares
constituting any series of Preferred Stock, to increase or decrease (but not
below the number of shares of any such series then outstanding) the number of
shares of any such series subsequent to the issue of shares of that series.
<PAGE>

                                      IV.

     The rights, preferences, privileges and restrictions granted to or imposed
upon the Common Stock and Preferred Stock are as follows:

     1.   Dividend Provisions.  The holders of shares of Series A Preferred
          -------------------
Stock ("Series A Preferred"), Series B Preferred Stock ("Series B Preferred"),
Series C Preferred Stock ("Series C Preferred") and Series D Preferred Stock
("Series D Preferred") shall be entitled to receive dividends, out of any assets
legally available therefor, prior and in preference to any declaration or
payment of any dividend (payable other than in Common Stock or other securities
and rights convertible into or entitling the holder thereof to receive, directly
or indirectly, additional shares of Common Stock of this Corporation) on the
Common Stock of this Corporation, at the rate of $0.03 per annum per share of
Series A Preferred (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares), $0.075 per annum
per share of Series B Preferred (as adjusted for any stock dividends,
combinations, splits, recapitalizations and the like with respect to such
shares), $0.10 per annum per share of Series C Preferred (as adjusted for any
stock dividends, combinations, splits, recapitalizations and the like with
respect to such shares) and $0.59 per annum per share of Series D Preferred (as
adjusted for any stock dividends, combinations, splits, recapitalizations and
the like with respect to such shares) or, if greater (as determined on a per
annum basis and on an as converted basis for the Preferred Stock), an amount
equal to that paid on the Common Stock. Such dividends shall be payable when,
as, and if declared by the Board of Directors, and shall not be cumulative, and
no right shall accrue to holders of Common Stock or Preferred Stock by reason of
the fact that dividends on said shares are not declared in any prior period.
After payment has been made to the holders of Preferred Stock of the full
amounts to which they shall be entitled as set forth in this Section 1, the
holders of Preferred Stock and Common Stock shall be entitled to receive ratably
on an as-converted basis any remaining funds declared as dividends.

     2.   Liquidation Preference.
          ----------------------

          (a) Preferred Preference.  In the event of any liquidation,
              --------------------
dissolution, or winding up of the Corporation, either voluntary or involuntary,
the holders of the Series C Preferred and Series D Preferred shall be entitled
to receive on a pro rata basis, prior and in preference to any distribution of
any of the assets or surplus funds of the Corporation to the holders of the
Series A Preferred, Series B Preferred and Common Stock, by reason of their
ownership of such stock, an amount per share equal to the sum of $1.25 per share
of Series C Preferred and $7.41 per share of Series D Preferred (in each case as
adjusted for any stock dividends, combinations, splits, recapitalizations and
the like with respect to such shares) plus declared and unpaid dividends, for
each share of Series C Preferred or Series D Preferred then held by them. If
upon the occurrence of such event, the assets and funds thus distributed among
the holders of the Series C Preferred and Series D Preferred shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then the entire assets and funds of the Corporation
legally available for distribution shall be distributed among the holders of the
Series C Preferred and Series D Preferred in proportion to the aggregate
liquidation preference of the shares held by each such holder.

                                      -2-
<PAGE>

          (b) After payment has been made to the holders of the Series C
Preferred and Series D Preferred of the full amounts to which they shall be
entitled as set forth in paragraph 2(a) above, the holders of Series A Preferred
and Series B Preferred shall be entitled to receive, prior and in preference to
any distribution of any of the assets of this Corporation to the holders of
Common Stock by reason of their ownership thereof, an amount per share equal to
$0.50 for each outstanding share of Series A Preferred (as adjusted for any
stock dividends, combinations, splits, recapitalizations and the like with
respect to such shares), and $1.25 for each outstanding share of Series B
Preferred (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares), plus an amount
equal to any declared but unpaid dividends for each share of Series A Preferred
and Series B Preferred then held by them. If upon the occurrence of such event,
the assets and funds thus distributed among the holders of Series A Preferred
and Series B Preferred shall be insufficient to permit the payment to such
holders of the full aforesaid preferential amounts, then the entire assets and
funds of this Corporation legally available for distribution shall be
distributed ratably among the holders of the Series A Preferred and Series B
Preferred in proportion to the aggregate Series A Preferred liquidation
preference and the Series B Preferred liquidation preference.

          (c) After payment has been made to the holders of the Preferred Stock
of the full amounts to which they shall be entitled to as set forth in
paragraphs 2(a) and 2(b) above, the holders of the Common Stock shall then be
entitled to receive the amount of $0.40 per share for each share of Common Stock
then held by them (as adjusted for any stock dividends, combinations, splits,
recapitalizations and the like with respect to such shares), plus an amount
equal to all declared but unpaid dividends for each share of Common Stock then
held by them.  If the assets and funds thus distributed among the holders of the
Common Stock shall be insufficient to permit the payment to such holders of the
full aforesaid amount, then the entire assets and funds of the Corporation
legally available for distribution, shall be distributed among the holders of
the Common Stock ratably on a per-share basis.

          (d) After payment has been made to the holders of the Preferred Stock
and the Common Stock of the full amount to which they shall be entitled as set
forth in paragraphs 2(a), 2(b) and 2(c) above, the holders of the Preferred
Stock and Common Stock shall be entitled to receive ratably on a per-share basis
all the remaining assets based upon the number of shares of Common Stock into
which each share of Preferred Stock is then convertible; provided, however, that
the holders of Preferred Stock shall not be entitled to receive pursuant to this
paragraph (d) (including amounts received pursuant to paragraphs 2 (a) and 2(b)
above) more than a total of $1.00 per share of Series A Preferred, $2.50 per
share of Series B Preferred, $2.50 per share of Series C Preferred and $14.82
per share of Series D Preferred then held by them (as adjusted for any stock
dividends, combinations, splits, recapitalizations and the like with respect to
such shares) plus declared and unpaid dividends.

          (e) After payment has been made to the holders of the Preferred Stock
and the Common Stock of the full amounts to which they shall be entitled as set
forth in paragraphs 2(a), 2(b), 2(c) and 2(d) above, the holders of the Common
Stock shall be entitled to receive ratably on a per-share basis all the
remaining assets.

                                      -3-
<PAGE>

          (f)  Mergers.  Unless waived by the approval (by vote or written
               -------
consent, as provided by law) of the holders of 66 2/3% of the then outstanding
Series C Preferred and holders of 66 2/3% of the then outstanding Series D
Preferred, for purposes of this Section 2, a merger or consolidation of the
Corporation with or into any other corporation or corporations, or the merger of
any other corporation or corporations into the Corporation, in which the
shareholders of the Corporation receive distributions in cash or securities of
another corporation or corporations as a result of such consolidation or merger,
a reorganization, including a sale of the capital stock of the Corporation,
where the shareholders of the Corporation immediately prior to the transaction
possess less than 50% of the voting power of the surviving entity (or its
parent) immediately after the transaction, or a sale of all or substantially all
of the assets of the Corporation, shall be treated as a liquidation, dissolution
or winding up of the Corporation; provided that the holders of the Preferred
Stock and the Common Stock shall each be paid the liquidation preference in cash
or in the securities received or in a combination thereof (which combination
shall be in the same proportions as the consideration received in the
transaction).  Any securities to be delivered to the holders of the Preferred
Stock and Common Stock upon merger, reorganization or sale of substantially all
the assets of the Corporation shall be valued as follows:

               (i)   if traded on a securities exchange, the value shall be
deemed to be the average of the closing prices of the securities on such
exchange over the 30-day period ending three (3) business days prior to the
closing;

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

               (iii) if there is no active public market, the value shall be the
fair market value thereof as mutually determined by the Corporation and the
holders of not less than a majority of the outstanding shares of the Preferred
Stock, provided that if the Corporation and the holders of a majority of the
outstanding shares of the Preferred Stock are unable to reach agreement, then by
independent appraisal by an investment banker hired and paid by the Corporation,
but acceptable to the holders of a majority of the outstanding shares of
Preferred Stock.

          (g)  As authorized by Section 402.5(c) of the California Corporations
Code, the provisions of Sections 502 and 503 of the California Corporations Code
shall not apply with respect to repurchase by the Corporation of shares of
Common Stock issued to or held by employees or consultants of the Corporation or
its subsidiaries upon termination of their employment or services pursuant to
agreement providing for the right of said repurchase.

     3.   Conversion.  The holders of Preferred Stock shall have conversion
          ----------
rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.  Each share of Preferred Stock shall be
               ----------------
convertible into share(s) of Common Stock without the payment of any additional
consideration by the holder thereof and, at the option of the holder thereof, at
any time after the date of issuance of such share, at the office of the
Corporation or any transfer agent for the Preferred Stock.  Each share of
Preferred Stock

                                      -4-
<PAGE>

shall be convertible into such number of fully paid and nonassessable shares of
Common Stock as is determined by dividing the applicable Original Issue Price of
such share of Preferred Stock by the Conversion Price (the "Conversion Price")
at the time in effect for a share of such series of Preferred Stock. The
Original Issue Price per share of Series A Preferred is $0.50, and the
Conversion Price per share of Series A Preferred initially shall be $0.50. The
Original Issue Price per share of Series B Preferred is $1.25, and the
Conversion Price per share of Series B Preferred initially shall be $1.25. The
Original Issue Price per share of Series C Preferred is $1.25, and the
Conversion Price per share of Series C Preferred initially shall be $1.25. The
Original Issue Price per share of Series D Preferred is $7.41, and the
Conversion Price per share of Series D Preferred initially shall be $7.41. The
Conversion Price of each series of Preferred Stock shall be subject to
adjustment from time to time as provided below. The number of shares of Common
Stock into which a share of Preferred Stock is convertible is hereinafter
referred to as the "Conversion Rate" of such series.

          (b) Automatic Conversion.  Each share of Preferred Stock shall
              --------------------
automatically be converted into shares of Common Stock at the then effective
Conversion Rate immediately upon the closing of a firm commitment underwritten
public offering pursuant to an effective registration statement under the
Securities Act of 1933, as amended, covering the offer and sale of Common Stock
in which the aggregate proceeds raised equals or exceeds $20,000,000 (a
"Qualified Public Offering").

              Notwithstanding the foregoing, each share of Series A Preferred,
Series B Preferred and Series C Preferred shall automatically be converted into
shares of Common Stock at the applicable effective Conversion Rate upon the
approval (by vote or written consent, as provided by law) of (i) the holders of
at least 2/3 of the then outstanding shares of Series A Preferred, Series B
Preferred and Series C Preferred (voting together as a separate class) and (ii)
the holders of at least 2/3 of the then outstanding shares of Series C
Preferred.

              Notwithstanding the foregoing, each share of Series D Preferred
shall automatically be converted into shares of Common Stock at the applicable
effective Conversion Rate upon the approval (by vote or written consent, as
provided by law) of the holders of at least 2/3 of the then outstanding shares
of Series D Preferred.

          (c) Mechanics of Conversion.  Before any holder of the Preferred Stock
              -----------------------
shall be entitled to convert the same into shares of Common Stock, he shall
surrender the certificate or certificates therefor, duly endorsed, at the office
of the Corporation or of any transfer agent for the Preferred Stock and shall
give written notice to the Corporation at such office that he elects to convert
the same (except that no such written notice of election to convert shall be
necessary in the event of an automatic conversion pursuant to Section 3(b)
hereof).  The Corporation shall, as soon as practicable thereafter, issue and
deliver at such office to such holder of Preferred Stock a certificate or
certificates for the number of shares of Common Stock to which such holder shall
be entitled.  Such conversion shall be deemed to have been made immediately
prior to the close of business on the date of such surrender of the shares of
Preferred Stock to be converted (except that in the case of an automatic
conversion pursuant to Section 3(b) hereof such conversion shall be deemed to
have been made immediately prior to the closing of the offering referred to in
Section 3(b)) and the person

                                      -5-
<PAGE>

or persons entitled to receive the shares of Common Stock issuable upon such
conversion shall be treated for all purposes as the record holder or holders of
such shares of Common Stock on such date.

          (d) Fractional Shares.  In lieu of any fractional shares to which the
              -----------------
holder of Preferred Stock would otherwise be entitled, the Corporation shall pay
cash equal to such fraction multiplied by the fair market value of one share of
each such series of Preferred Stock as determined by the Board of Directors of
the Corporation.  Whether or not fractional shares are issuable upon such
conversion shall be determined on the basis of the total number of shares of
Preferred Stock of each holder to be converted at such time into Common Stock
and the number of shares of Common Stock issuable upon such aggregate
conversion.

          (e) Adjustment of Conversion Price.  The Conversion Price of each
              ------------------------------
series of Preferred Stock shall be subject to adjustment from time to time as
follows:

              (i) If the Corporation shall issue any Common Stock other than
"Excluded Stock", as defined below, without consideration or for consideration
per share less than the applicable Conversion Price for such series in effect on
the date of and immediately prior to such issuance, then and in such event, the
Conversion Price in effect for such series shall be reduced, concurrently with
such issuance, to a price determined by multiplying such Conversion Price by a
fraction, the numerator of which shall be the total number of shares of Common
Stock outstanding (including any shares of Common Stock issuable upon conversion
of the Preferred Stock, or deemed to have been issued pursuant to subdivision
(3) of this clause (i) and to clause (ii) below) immediately prior to such
issuance plus the number of shares of Common Stock which the aggregate
consideration received by the Corporation for the total number of shares of
Common Stock so issued would purchase at such Conversion Price; and the
denominator of which shall be the total number of shares of Common Stock
outstanding (including any shares of Common Stock issuable upon conversion of
the Preferred Stock or deemed to have been issued pursuant to subdivision (3) of
this clause (i) and to clause (ii) below) immediately prior to such issuance
plus the additional shares of Common Stock issued in such issuance (but not
including any additional shares of Common Stock deemed to be issued as a result
of any adjustment in the Conversion Price resulting from such issuance).

              For purposes of any adjustment of the Conversion Price pursuant to
this clause (i), the following provisions shall be applicable:

                         (1) In the case of the issuance of Common Stock for
cash, the consideration shall be deemed to be the amount of cash paid therefor
after deducting any discounts or commissions paid or incurred by the Corporation
in connection with the issuance and sale thereof.

                         (2) In the case of the issuance of Common Stock for a
consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair market value thereof as determined by the
Board of Directors of the Corporation, in accordance with generally accepted
accounting treatment; provided, however, that if, at the time
                      --------  -------

                                      -6-
<PAGE>

of such determination, the Corporation's Common Stock is traded in the over-the-
counter market or on a national or regional securities exchange, such fair
market value as determined by the board of directors of the Corporation shall
not exceed the aggregate "Current Market Price" (as defined below) of the shares
of Common Stock being issued.

                         (3) In the case of the issuance of (i) options to
purchase or rights to subscribe for Common Stock (other than Excluded Stock),
(ii) securities by their terms convertible into or exchangeable for Common Stock
(other than Excluded Stock), or (iii) options to purchase or rights to subscribe
for such convertible or exchangeable securities:

                         (A) the aggregate maximum number of shares of Common
Stock deliverable upon exercise of such options to purchase or rights to
subscribe for Common Stock shall be deemed to have been issued at the time such
options or rights were issued and for a consideration equal to the consideration
(determined in the manner provided in subdivisions (1) and (2) above), if any,
received by the Corporation upon the issuance of such options or rights plus the
minimum purchase price provided in such options or rights for the Common Stock
covered thereby;

                         (B) the aggregate maximum number of shares of Common
Stock deliverable upon conversion of or in exchange for any such convertible or
exchangeable securities or upon the exercise of options to purchase or rights to
subscribe for such convertible or exchangeable securities and subsequent
conversion or exchange thereof, shall be deemed to have been issued at the time
such securities were issued or such options or rights were issued and for a
consideration equal to the consideration received by the Corporation for any
such securities and related options or rights (excluding any cash received on
account of accrued interest or accrued dividends), plus the minimum additional
consideration, if any, to be received by the Corporation upon the conversion or
exchange of such securities or the exercise of any related options or rights
(the consideration in each case to be determined in the manner provided in
subdivisions (1) and (2) above);

                         (C) on any change in the number of shares of Common
Stock deliverable upon exercise of any such options or rights or conversion of
or exchange for such convertible or exchangeable securities, or on any change in
the minimum purchase price of such options, rights or securities, other than a
change resulting from the antidilution provisions of such options, rights or
securities, the Conversion Price shall forthwith be readjusted to such
Conversion Price as would have been obtained had the adjustment made upon (x)
the issuance of such options, rights or securities not exercised, converted or
exchanged prior to such change, as the case may be, been made upon the basis of
such change or (y) the options or rights related to such securities not
converted or exchanged prior to such change, as the case may be, been made upon
the basis of such change; and

                         (D) on the expiration of any such options or rights,
the termination of any such rights to convert or exchange or the expiration of
any options or rights related to such convertible or exchangeable securities,
the Conversion Price shall forthwith be readjusted to such Conversion Price as
would have been obtained had the adjustment made upon the

                                      -7-
<PAGE>

issuance of such options, rights, convertible or exchangeable securities or
options or rights related to such convertible or exchangeable securities, as the
case may be, been made upon the basis of the issuance of only the number of
shares of Common Stock actually issued upon the exercise of such options or
rights, upon the conversion or exchange of such convertible or exchangeable
securities or upon the exercise of the options or rights related to such
convertible or exchangeable securities, as the case may be.

               (ii)  "Excluded Stock" shall mean:

                     (1) all shares of Common Stock issued and outstanding on
the date this document is filed with the California Secretary of State and all
shares issuable upon exercise of options or warrants outstanding on the date
this document is filed with the California Secretary of State;

                     (2) all shares of Series A Preferred, Series B Preferred,
Series C Preferred and Series D Preferred and the Common Stock into which such
shares are convertible;

                     (3) up to 1,562,808 shares of Common Stock, warrants or
options to purchase Common Stock or other securities issued to officers,
directors, consultants or employees of the Corporation pursuant to any plan or
arrangement approved by the Board of Directors of the Corporation; and

                     (4) shares of Common Stock, warrants or options to purchase
Common Stock or other securities issued to officers, directors, consultants or
employees of the Corporation pursuant to any plan or arrangement approved by a
2/3 vote of the Board of Directors of the Corporation.

                     All outstanding shares of Excluded Stock (including any
shares issuable upon conversion of the Preferred Stock) shall be deemed to be
outstanding for all purposes of the computations of Section 3(e)(i) above.

               (iii) If the number of shares of Common Stock outstanding at any
time after the date hereof is increased by a stock dividend payable in shares of
Common Stock or by a subdivision or split-up of shares of Common Stock, then, on
the date such payment is made or such change is effective, the respective
Conversion Prices of Series A Preferred, Series B Preferred, Series C Preferred
and Series D Preferred shall be appropriately decreased so that the number of
shares of Common Stock issuable on conversion of any shares of such series of
Preferred Stock shall be increased in proportion to such increase of outstanding
shares of Common Stock.

               (iv)  If the number of shares of Common Stock outstanding at any
time after the date hereof is decreased by a combination of the outstanding
shares of Common Stock, then, on the effective date of such combination, the
respective Conversion Prices of Series A Preferred, Series B Preferred, Series C
Preferred and Series D Preferred shall be appropriately increased so that the
number of shares of Common Stock issuable on conversion of any shares of a

                                      -8-
<PAGE>

series of Preferred Stock shall be decreased in proportion to such decrease in
outstanding shares of Common Stock.

               (v)    In case the Corporation shall declare a cash dividend upon
its Common Stock payable otherwise than out of retained earnings or shall
distribute to holders of its Common Stock shares of its capital stock (other
than Common Stock), stock or other securities of other persons, evidences of
indebtedness issued by the Corporation or other persons, assets (excluding cash
dividends) or options or rights (excluding options to purchase and rights to
subscribe for Common Stock or other securities of the Corporation convertible
into or exchangeable for Common Stock), then, in each such case, the holders of
shares of Preferred Stock shall, concurrent with the distribution to holders of
Common Stock, receive a like distribution based upon the number of shares of
Common Stock into which such shares of Preferred Stock are convertible.

               (vi)   In case, at any time after the date hereof, of any capital
reorganization, or any reclassification of the stock of the Corporation (other
than as a result of a stock dividend or subdivision, split-up or combination of
shares), or the consolidation or merger of the Corporation with or into another
person (other than a consolidation or merger in which the Corporation is the
continuing entity and which does not result in any change in the Common Stock),
or of the sale or other disposition of all or substantially all the properties
and assets of the Corporation, the shares of Preferred Stock shall, after such
reorganization, reclassification, consolidation, merger, sale or other
disposition, be convertible into the kind and number of shares of stock or other
securities or property of the Corporation or otherwise to which such holder
would have been entitled if immediately prior to such reorganization,
reclassification, consolidation, merger, sale or other disposition he had
converted his shares of Preferred Stock into Common Stock.  The provisions of
this clause (vi) shall similarly apply to successive reorganizations,
reclassifications, consolidations, mergers, sales or other dispositions.

               (vii)  All calculations under this Section 3 shall be made to the
nearest cent or to the nearest one hundredth (1/100) of a share, as the case may
be.

               (viii) For the purpose of any computation pursuant to this
Section 3(e), the "Current Market Price" at any date of one share of Common
Stock, shall be deemed to be the average of the highest reported bid and the
lowest reported offer prices on the preceding business day as furnished by the
National Quotation Bureau, Incorporated (or equivalent recognized source of
quotations); provided, however, that if the Common Stock is not traded in such
             --------  -------
manner that the quotations referred to in this clause (viii) are available for
the period required hereunder, Current Market Price shall be determined in good
faith by the Board of Directors of the Corporation, but if challenged by the
holders of more than 50% of the outstanding Series A Preferred, Series B
Preferred, Series C Preferred and Series D Preferred, voting as separate
classes, then as determined by an independent appraiser selected by the Board of
Directors of the Corporation, the cost of such appraisal to be borne equally by
the Corporation and the challenging parties.

          (f)  Minimal Adjustments.  No adjustment in the Conversion Price need
               -------------------
be made if such adjustment would result in a change in the Conversion Price of
less than $0.01.  Any

                                      -9-
<PAGE>

adjustment of less than $0.01 which is not made shall be carried forward and
shall be made at the time of and together with any subsequent adjustment which,
on a cumulative basis, amounts to an adjustment of $0.01 or more in the
Conversion Price.

          (g) No Impairment.  Without the consent of the majority of the
              -------------
outstanding shares of Preferred Stock, the Corporation will not through any
reorganization, recapitalization, transfer of assets, consolidation, merger,
dissolution, issue or sale of securities or any other voluntary action, avoid or
seek to avoid the observance or performance of any of the terms to be observed
or performed hereunder by the Corporation, but will at all times in good faith
assist in the carrying out of all the provisions of this Section 3 and in the
taking of all such action as may be necessary or appropriate in order to protect
the Conversion Rights of the holders of Preferred Stock against impairment.

          (h) Certificate as to Adjustments.  Upon the occurrence of each
              -----------------------------
adjustment or readjustment of the Conversion Rate pursuant to this Section 3,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Preferred Stock a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based.  The Corporation shall, upon written request at any time
of any holder of Preferred Stock, furnish or cause to be furnished to such
holder a like certificate setting forth (i) such adjustments and readjustments,
(ii) the Conversion Rate of such series at the time in effect, and (iii) the
number of shares of Common Stock and the amount, if any, of other property which
at the time would be received upon the conversions of such holder's shares of
Preferred Stock.

          (i) Notices of Record Date.  In the event of any taking by the
              ----------------------
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property or to receive any other right, the Corporation
shall mail to each holder of Preferred Stock at least ten (10) days prior to
such record date, a notice specifying the date on which any such record is to be
taken for the purpose of such dividend or distribution or right, and the amount
and character of such dividend, distribution or right.

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

                                     -10-
<PAGE>

          (k) Notices.  Any notice required by the provisions of this Section 3
              -------
to be given to the holder of shares of Preferred Stock shall be deemed given if
deposited in the United States mail, postage prepaid, and addressed to each
holder of record at his address appearing on the books of the Corporation.

          (l) Reissuance of Converted Shares.  No shares of Preferred Stock
              ------------------------------
which have been converted into Common Stock after the original issuance thereof
shall ever again be reissued and all such shares so converted shall upon such
conversion cease to be a part of the authorized shares of the Corporation.

          (m) Special Adjustment of Conversion Price for Qualified Public
              -----------------------------------------------------------
Offering.  Notwithstanding Section 3(a) above, in the event the Series D
- --------
Preferred is automatically converted into Common Stock by reason of a Qualified
Public Offering as set forth in Section 3(b) hereof, and the initial public
offering price per share (the "IPO Price") is less than 125% of the Original
Issue Price of the Series D Preferred (adjusted for stock splits and the like),
then the Conversion Price per share of Series D Preferred shall be reduced to a
number equal to the quotient of (i) the Conversion Price of the Series D
Preferred in effect immediately prior to such offering divided by (ii) a
fraction, the numerator of which is the Original Issue Price of the Series D
Preferred multiplied by 1.25 and the denominator of which is the IPO Price.

     4.   Voting Rights.  The holder of each share of Preferred Stock shall be
          -------------
entitled to the number of votes equal to the number of shares of Common Stock
into which each share of Preferred Stock could be converted on the record date
for the vote or consent of shareholders written consent and, except as otherwise
required by law or provided for herein, shall have voting rights and powers
equal to the voting rights and powers of the Common Stock.  The holder of each
share of Preferred Stock shall be entitled to notice of any shareholders'
meeting in accordance with the bylaws of the Corporation and shall vote with
holders of the Common Stock upon the election of directors, except as provided
in Section 5 herein, and upon any other matter submitted to a vote of
shareholders, except those matters required by law to be submitted to a class
vote.  Fractional votes shall not, however, be permitted and any fractional
voting rights resulting from the above formula (after aggregating all shares of
Common Stock into which shares of Preferred Stock held by each holder could be
converted) shall be rounded to the nearest whole number (with one-half rounded
upward to one).

     5.   Election of Directors.  At each election of the Corporation's
          ---------------------
directors, (i) the holders of the Corporation's Series A Preferred shall have
the right, voting as a separate class (with cumulative voting rights as among
themselves in accordance with Section 708 of the California Corporations Code)
to elect one (1) member of the Board of Directors, (ii) the holders of the
Corporation's Series B Preferred shall have the right, voting as a separate
class (with cumulative voting rights as among themselves in accordance with
Section 708 of the California Corporations Code) to elect one (1) member of the
Board of Directors, (iii) the holders of the Corporation's Series C Preferred
shall have the right, voting as a separate class (with cumulative voting rights
as among themselves in accordance with Section 708 of the California
Corporations Code) to elect two (2) members of the Board of Directors, and (iv)
the holders of the Corporation's Common Stock

                                     -11-
<PAGE>

shall have the right, voting as a separate class (with cumulative voting rights
as among themselves in accordance with Section 708 of the California
Corporations Code) to elect two (2) members of the Board of Directors. Any
additional directors shall be elected by all of the holders of Common Stock and
Preferred Stock, voting as a single class.

acquire any security junior to the Preferred Stock other than repurchases at
cost from employees, consultants, lessors or suppliers upon termination of
employment, consulting, lessor-lessee, or supplier-purchaser relationship,
respectively; or

               (vi)  voluntarily dissolve or liquidate the Corporation.

          (b)  Notwithstanding the foregoing Section 6(a), in addition to any

law) of the holders of at least a majority of the then outstanding shares of
Series C Preferred:

               (i)   materially adversely change the rights, preferences,

                                     -12-
<PAGE>

               (ii)  increase or decrease the aggregate number of authorized

any such liquidation, dissolution, merger or sale of all or substantially all of
the assets of the Corporation is less than $2.50 per share (as adjusted for any
stock dividends, combinations, splits, recapitalizations and the like with
respect to such shares).

Preferred, materially adversely change the rights, preferences, privileges or
restrictions of the Series D Preferred.

          (e)  Unless otherwise required by California law or except as provided
herein, the holders of Common Stock will not have the right to vote as a
separate class on any matter.

     7.   Repurchase of Shares.  In connection with repurchases by this
          --------------------
Corporation of its Common Stock, pursuant to its agreements with certain of the
holders thereof, Sections 502 and 503 of the California General Corporation Law
shall not apply in whole or in part with respect to such repurchases.

     8.   Series B Preferred - Right of Redemption.
          ----------------------------------------

          (a)  Subject to Section 8(e) herein, the Corporation shall be
obligated to redeem the Series B Preferred as follows:

               (i) At any time after March 31, 2004, the holders of a majority
of the then outstanding shares of Series B Preferred (the "Series B Initiating
Holders") may require the Corporation to the extent it may lawfully do so, to
redeem all of the outstanding Series B Preferred in three (3) equal annual
installments with the first installment date being the date forty-five (45) days
after receipt by the Corporation of the Series B Exercise Notice (as defined
below), the second

                                     -13-
<PAGE>

installment being the date one (1) year from the first installment date and the
last installment date being a date two (2) years from such first installment
date (each a "Series B Redemption Date"). The Corporation shall effect such
redemptions on the applicable Series B Redemption Date by paying in cash in
exchange for each share of Series B Preferred to be redeemed on each applicable
Series B Redemption Date a sum equal to the fair market value per share of
Series B Preferred as of the date of receipt by the Corporation of the Series B
Exercise Notice plus all accrued and unpaid dividends thereon. The fair market
value per share of Series B Preferred for the purposes of this Section 8, shall
be determined by the Board of Directors of the Corporation. If such
determination is unacceptable to the holders of a majority of the Series B
Preferred, then the fair market value per share of Series B Preferred shall be
determined by an investment banking firm mutually acceptable to the Corporation
and the holders of a majority of the Series B Preferred. The Series B Initiating
Holders shall have the right to revoke a Series B Exercise Notice by giving
written notice to the Corporation within fifteen (15) days after their receipt
of the Series B Redemption Notice (as defined below). The total amount to be
paid for the Series B Preferred is hereinafter referred to as the "Series B
Redemption Price." The number of shares of Series B Preferred that the
Corporation shall be required to redeem on any one Series B Redemption Date
shall be equal to the amount determined by dividing (i) the aggregate number of
shares of Series B Preferred outstanding immediately prior to the Series B
Redemption Date by (ii) the number of remaining Series B Redemption Dates
(including the Series B Redemption Date to which such calculation applies).
Shares subject to redemption pursuant to this Section 8(a) shall be redeemed
from each holder of Series B Preferred on a pro rata basis.

               (ii) At any time after March 31, 2004, the Series B Initiating
Holders can elect to exercise the right of first redemption pursuant to this
Section 8(a) by providing written notice (the "Series B Exercise Notice") to the
Corporation.  Within fifteen (15) days after the receipt of the Series B
Exercise Notice, the Corporation shall (i) send a notice (a "Series B Redemption
Notice") to each holder of record of the Series B Preferred to be redeemed at
the address of such holder appearing on the books of the Corporation setting
forth (a) the Series B Redemption Price for the shares to be redeemed and (b)
the place at which such holders may obtain payment of the Series B Redemption
Price upon surrender of their share certificates, and (ii) send a notice to each
holder of record of the Series C Preferred at the address of such holder
appearing on the books of the Corporation notifying such holders of the election
of the holders of the Series B Preferred to exercise the right of redemption of
the Series B Preferred.  If the Corporation does not have sufficient funds
legally available to redeem all shares to be redeemed at any Series B Redemption
Date (including, if applicable, those to be redeemed at the option of the
Corporation), then it shall redeem such shares pro rata (based on the portion of
the aggregate Series B Redemption Price payable to them) to the extent possible
and shall redeem the remaining shares to be redeemed as soon as sufficient funds
are legally available.

          (b)  On each Series B Redemption Date, the Corporation shall deposit
the portion of the Series B Redemption Price sufficient to redeem the shares to
be redeemed upon such Series B Redemption Date with a bank or trust corporation
having aggregate capital and surplus in excess of $100,000,000, as a trust fund,
with irrevocable instructions and authority to the bank or trust corporation to
pay, on and after such Series B Redemption Date, the applicable portion of the

                                     -14-
<PAGE>

Series B Redemption Price to their respective holders upon the surrender of
their share certificates.  Any monies deposited by the Corporation pursuant to
this Section 8(b) for the redemption of shares thereafter converted into shares
of Common Stock pursuant to Section 3 hereof no later than the fifth (5th) day
preceding the applicable Series B Redemption Date shall be returned to the
Corporation forthwith upon such conversion.  The balance of any funds deposited
by the Corporation pursuant to this Section 8(b) remaining unclaimed at the
expiration of one (1) year following such Series B Redemption Date shall be
returned to the Corporation.

          (c) On or after such Series B Redemption Date, each holder of shares
of Series B Preferred to be redeemed shall surrender such holder's certificates
representing such shares to the Corporation in the manner and at the place
designated in the Redemption Notice, and thereupon the applicable portion of the
Series B Redemption Price of such shares shall be payable to the order of the
person whose name appears on such certificate or certificates as the owner
thereof and each surrendered certificate shall be canceled. In the event less
than all the shares represented by such certificates are redeemed, a new
certificate shall be issued representing the unredeemed shares.  From and after
the date the Corporation deposits funds pursuant to Section 8(b) hereof with
respect to shares to be redeemed on such Series B Redemption Date, unless there
shall have been a default in payment of the applicable portion of the Series B
Redemption Price or the Corporation is unable to pay the applicable portion of
the Series B Redemption Price due to not having sufficient legally available
funds, all rights of the holders of such shares as holders of Series B Preferred
(except the right to receive the Series B Redemption Price without interest upon
surrender of their certificates), shall cease and terminate with respect to such
shares, provided that in the event that shares of Series B Preferred are not
redeemed due to a default in payment by the Corporation or because the
Corporation does not have sufficient legally available funds, such shares of
Series B Preferred shall remain outstanding and shall be entitled to all of the
rights and preferences provided herein.

          (d) In the event of a call for redemption of any shares of Series B
Preferred, the Conversion Rights (as defined in Section 3) for the shares of
Series B Preferred to be redeemed on a particular Series B Redemption Date shall
terminate at the close of business on the fifth (5th) day preceding such Series
B Redemption Date, unless default is made in payment of the Series B Redemption
Price.

          (e) In the event that the Series B Initiating Holders have elected to
exercise their right of redemption pursuant to this Section 8 and to the extent
that the Company receives the Series C Exercise Notice (as defined below) from
the Series C Initiating Holders (as defined below) or the Series D Exercise
Notice (as defined below) from the Series D Initiating Holders (as defined
below) prior to the deposit by the Company of funds pursuant to Section 8(b)
hereof with respect to any applicable Series B Redemption Date, the right of
redemption of the Series C Preferred and the Series D Preferred shall be
superior and in preference to the right of redemption of the Series B Preferred
and the holders of the Series C Preferred and Series D Preferred shall be
entitled to receive the full amount of the Series C Redemption Price and the
Series D Redemption Price out of legally available funds of the Corporation
prior to the payment of any portion of the Series B Redemption Price not
previously deposited by the Company pursuant to Section 8(b) or required to be
paid to the holders of the Series B Preferred pursuant to the last sentence of
Section 8(a)(ii) hereof.  In such

                                     -15-
<PAGE>

event, after the full amount of the Series C Redemption Price and the Series D
Redemption Price has been deposited pursuant to Sections 9(b) and 10(b) below,
the holders of the Series B Preferred shall be entitled to receive the full
amount of the Series B Redemption Price of the Series B Preferred. If the funds
of the Corporation legally available for redemption of shares of the Series B
Preferred, Series C Preferred or Series D Preferred are insufficient to redeem
the total number of shares of Series B Preferred, Series C Preferred or Series D
Preferred to be redeemed on a Series B Redemption Date, Series C Redemption Date
or Series D Redemption Date, those funds which are legally available will be
used to redeem the maximum possible number of such shares from first the holders
of the Series C Preferred and Series D Preferred to the extent of the full
amount of the Series C Redemption Price and Series D Redemption Price pro rata
based on the relative redemption price of such series and next to the holders of
the Series B Preferred to the extent of the full amount of the Series B
Redemption Price. The shares of Series B Preferred, Series C Preferred or Series
D Preferred not redeemed, as the case may be, shall remain outstanding and
entitled to all the rights and preferences provided herein, including the rights
of conversion set forth in Section 3. At any time thereafter when additional
funds of the Corporation are legally available for the redemption of shares of
Series B Preferred, Series C Preferred or Series D Preferred, as the case may
be, such funds will immediately be used to redeem the balance of the shares
which the Corporation has become obliged to redeem on any Redemption Date but
which it has not redeemed.

     9.   Series C Preferred - Right of Redemption.
          ----------------------------------------

          (a)  Subject to Section 8(e) above, the Corporation shall be obligated
to redeem the Series C Preferred as follows:

               (i)   Beginning on or after March 31, 2004, the holders of 66
2/3% of the then outstanding shares of Series C Preferred (the "Series C
Initiating Holders") may require the Corporation to the extent it may lawfully
do so, to redeem all of the outstanding Series C Preferred. Such redemption
shall occur on the 45th day following the Corporation's receipt of the Series C
Exercise Notice (as defined below) (such date being herein referred to as the
"Initial Series C Redemption Date"), provided that the Series C Initiating
                                     --------
Holders shall have the right to revoke a Series C Exercise Notice by giving
written notice to the Corporation within fifteen (15) days after their receipt
of the Series C Redemption Notice, and provided further that in lieu of
                                       -------- -------
redeeming all of the Series C Preferred on the Initial Series C Redemption Date
the Corporation shall have the right to redeem the Series C Preferred in three
(3) equal installments, with the first installment date being the Initial Series
C Redemption Date, the second installment being the first anniversary of the
Initial Series C Redemption Date and the last installment being the second
anniversary of the Initial Series C Redemption Date (the Initial Series C
Redemption Date and each of such other redemption dates being herein referred to
as a "Series C Redemption Date"). The Corporation shall effect such redemptions
on the applicable Series C Redemption Date by paying in cash in exchange for
each share of Series C Preferred to be redeemed on each applicable Series C
Redemption Date, a sum equal to the fair market value per share of Series C
Preferred as of the date of receipt by the Corporation of the Series C Exercise
Notice plus all accrued and unpaid dividends with respect to such shares thereon
plus interest at the rate of 10% per annum payable on the amount of the unpaid
Series C Redemption Price (as hereinafter defined) accruing from the Initial
Series C Redemption

                                     -16-
<PAGE>

Date until paid. The fair market value per share of Series C Preferred for the
purposes of this Section 9, shall be determined by the Board of Directors of the
Corporation. If such determination is unacceptable to the holders of a majority
of the Series C Preferred, then the fair market value per share of Series C
Preferred shall be determined by an investment banking firm mutually acceptable
to the Corporation and the holders of a majority of the Series C Preferred. The
total amount to be paid for the Series C Preferred is hereinafter referred to as
the "Series C Redemption Price." The number of shares of Series C Preferred that
the Corporation shall be required to redeem on any one Series C Redemption Date
shall be equal to the amount determined by dividing (i) the aggregate number of
shares of Series C Preferred outstanding immediately prior to the Series C
Redemption Date by (ii) the number of remaining Series C Redemption Dates
(including the Series C Redemption Date to which such calculation applies).
Shares subject to redemption pursuant to this Section 9(a) shall be redeemed
from each holder of Series C Preferred on a pro rata basis.

               (ii)  At any time after March 31, 2004, the Series C Initiating
Holders can elect to exercise the right of first redemption pursuant to this
Section 9(a) by providing written notice (the "Series C Exercise Notice") to the
Corporation. Within fifteen (15) days after the receipt of the Series C Exercise
Notice, the Corporation shall (i) send a notice (a Series C "Redemption Notice")
to each holder of record of the Series C Preferred to be redeemed at the address
of such holder appearing on the books of the Corporation setting forth (a) the
Series C Redemption Price for the shares to be redeemed and (b) the place at
which such holders may obtain payment of the Series C Redemption Price upon
surrender of their share certificates. If the Corporation does not have
sufficient funds legally available to redeem all shares to be redeemed at the
Series C Redemption Date (including, if applicable, those to be redeemed at the
option of the Corporation), then it shall redeem such shares pro rata (based on
the portion of the aggregate Series C Redemption Price payable to them) to the
extent possible and shall redeem the remaining shares to be redeemed as soon as
sufficient funds are legally available.

          (b)  On or prior to the Series C Redemption Date, the Corporation
shall deposit the applicable portion of the Series C Redemption Price of the
shares to be redeemed on such Series C Redemption Date with a bank or trust
corporation having aggregate capital and surplus in excess of $100,000,000, as a
trust fund, with irrevocable instructions and authority to the bank or trust
corporation to pay, on and after such Series C Redemption Date, the applicable
portion of the Series C Redemption Price of the shares to their respective
holders upon the surrender of their share certificates. Any monies deposited by
the Corporation pursuant to this Section 9(b) for the redemption of shares
thereafter converted into shares of Common Stock pursuant to Section 3 hereof no
later than the fifth (5th) day preceding the Series C Redemption Date shall be
returned to the Corporation forthwith upon such conversion. The balance of any
funds deposited by the Corporation pursuant to this Section 9(b) remaining
unclaimed at the expiration of one (1) year following such Series C Redemption
Date shall be returned to the Corporation.

          (c)  On or after such Series C Redemption Date, each holder of shares
of Series C Preferred to be redeemed shall surrender such holder's certificates
representing such shares to the Corporation in the manner and at the place

available funds, all rights of the holders of such shares as holders of Series C
Preferred (except the right to receive the Series C Redemption Price without
interest upon surrender of their certificates), shall cease and terminate with
respect to such shares, provided that in the event that shares of Series C
Preferred are not redeemed due to a default in payment by the Corporation or
because the Corporation does not have sufficient legally available funds, such
shares of Series C Preferred shall remain outstanding and shall be entitled to
all of the rights and preferences provided herein.

     10.  Series D Preferred - Right of Redemption.
          ----------------------------------------

          (a)  Subject to Section 8(e) above, the Corporation shall be obligated
to redeem the Series D Preferred as follows:

                 (i)   Beginning on or after March 31, 2004, the holders of 66
2/3% of the then outstanding shares of Series D Preferred (the "Series D
Initiating Holders") may require the Corporation to the extent it may lawfully
do so, to redeem all of the outstanding Series D Preferred. Such redemption
shall occur on the 45th day following the Corporation's receipt of the Series D
Exercise Notice (as defined below) (such date being herein referred to as the
"Initial Series D Redemption Date"), provided that the Series D Initiating
                                     --------
Holders shall have the right to revoke a Series D Exercise Notice by giving
written notice to the Corporation within fifteen (15) days after their receipt
of the Series D Redemption Notice, and provided further that in lieu of
                                       -------- -------
redeeming all of the Series D Preferred on the Initial Series D Redemption Date
the Corporation shall have the right to redeem the Series D Preferred in three
(3) equal installments, with the first installment date being the Initial Series
D Redemption Date, the second installment being the first anniversary of the
Initial Series D Redemption Date and the last installment being the second
anniversary of the Initial Series D Redemption Date (the Initial Series D
Redemption Date and each of such other redemption dates being herein referred to
as a "Series D Redemption Date"). The Corporation shall effect such redemptions
on the applicable Series D Redemption Date by paying in cash in exchange for
each share of Series D Preferred to be redeemed on each applicable Series D
Redemption Date, a sum equal to the fair market value per share of Series D
Preferred as of the date of receipt by the Corporation of the Series D Exercise
Notice plus all accrued and unpaid dividends with respect to such shares thereon
plus interest at the rate of 10% per annum payable on the amount of the unpaid

                                     -18-
<PAGE>

Series D Redemption Price (as hereinafter defined) accruing from the Initial
Series D Redemption Date until paid. The fair market value per share of Series D
Preferred for the purposes of this Section 10, shall be determined by the Board
of Directors of the Corporation. If such determination is unacceptable to the
holders of a majority of the Series D Preferred, then the fair market value per
share of Series D Preferred shall be determined by an investment banking firm
mutually acceptable to the Corporation and the holders of a majority of the
Series D Preferred. The total amount to be paid for the Series D Preferred is
hereinafter referred to as the "Series D Redemption Price." The number of shares
of Series D Preferred that the Corporation shall be required to redeem on any
one Series D Redemption Date shall be equal to the amount determined by dividing
(i) the aggregate number of shares of Series D Preferred outstanding immediately
prior to the Series D Redemption Date by (ii) the number of remaining Series D
Redemption Dates (including the Series D Redemption Date to which such
calculation applies). Shares subject to redemption pursuant to this Section
10(a) shall be redeemed from each holder of Series D Preferred on a pro rata
basis.

               (ii)  At any time after March 31, 2004, the Series D Initiating
Holders can elect to exercise the right of first redemption pursuant to this
Section 10(a) by providing written notice (the "Series D Exercise Notice") to
the Corporation. Within fifteen (15) days after the receipt of the Series D
Exercise Notice, the Corporation shall (i) send a notice (a Series D "Redemption
Notice") to each holder of record of the Series D Preferred to be redeemed at
the address of such holder appearing on the books of the Corporation setting
forth (a) the Series D Redemption Price for the shares to be redeemed and (b)
the place at which such holders may obtain payment of the Series D Redemption
Price upon surrender of their share certificates. If the Corporation does not
have sufficient funds legally available to redeem all shares to be redeemed at
the Series D Redemption Date (including, if applicable, those to be redeemed at
the option of the Corporation), then it shall redeem such shares pro rata (based
on the portion of the aggregate Series D Redemption Price payable to them) to
the extent possible and shall redeem the remaining shares to be redeemed as soon
as sufficient funds are legally available.

          (b)  On or prior to the Series D Redemption Date, the Corporation
shall deposit the applicable portion of the Series D Redemption Price of the
shares to be redeemed on such Series D Redemption Date with a bank or trust
corporation having aggregate capital and surplus in excess of $100,000,000, as a
trust fund, with irrevocable instructions and authority to the bank or trust
corporation to pay, on and after such Series D Redemption Date, the applicable
portion of the Series D Redemption Price of the shares to their respective
holders upon the surrender of their share certificates. Any monies deposited by
the Corporation pursuant to this Section 10(b) for the redemption of shares
thereafter converted into shares of Common Stock pursuant to Section 3 hereof no
later than the fifth (5th) day preceding the Series D Redemption Date shall be
returned to the Corporation forthwith upon such conversion. The balance of any
funds deposited by the Corporation pursuant to this Section 10(b) remaining
unclaimed at the expiration of one (1) year following such Series D Redemption
Date shall be returned to the Corporation.

          (c)  On or after such Series D Redemption Date, each holder of shares
of Series D Preferred to be redeemed shall surrender such holder's certificates
representing such shares to the Corporation in the manner and at the place
designated in the Series D Redemption Notice, and

                                     -19-
<PAGE>

thereupon the applicable portion of the Series D Redemption Price of such shares
shall be payable to the order of the person whose name appears on such
certificate or certificates as the owner thereof and each surrendered
certificate shall be canceled. In the event less than all the shares represented
by such certificates are redeemed, a new certificate shall be issued
representing the unredeemed shares. From and after the date the Corporation
deposits funds pursuant to Section 10(b) hereof with respect to shares to be
redeemed on such Series D Redemption Date, unless there shall have been a
default in payment of the applicable portion of the Series D Redemption Price or
the Corporation is unable to pay the applicable portion of the Series D
Redemption Price due to not having sufficient legally available funds, all
rights of the holders of such shares as holders of Series D Preferred (except
the right to receive the Series D Redemption Price without interest upon
surrender of their certificates), shall cease and terminate with respect to such
shares, provided that in the event that shares of Series D Preferred are not
redeemed due to a default in payment by the Corporation or because the
Corporation does not have sufficient legally available funds, such shares of
Series D Preferred shall remain outstanding and shall be entitled to all of the
rights and preferences provided herein.

          (d)  In the event of a call for redemption of any shares of Series D
Preferred, the Conversion Rights (as defined in Section 3) for the shares of
Series D Preferred to be redeemed on a particular Series D Redemption Date shall
terminate at the close of business on the fifth (5th) day preceding such Series
D Redemption Date, unless default is made in payment of the Series D Redemption
Price.

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"), except as provided in Section 3(f) below. 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.

                (iii) 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.

                (iv)  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.

               (v)   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, 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.

               (vi)  Exception to Assignments. I understand that the provisions
                     ------------------------
of this Agreement requiring assignment of Inventions to the Company do not apply
to any invention which qualifies fully under the provisions of California Labor
Code Section 2870 (attached hereto as Exhibit B). I will advise the Company
                                      ---------
promptly in writing of any inventions that I believe meet the criteria in
California Labor Code Section 2870 and not otherwise disclosed on Exhibit A.
                                                                  ---------

          (d)  Conflicting Employment.  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.

          (e)  Returning the 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 Certification" attached hereto as Exhibit
                                                                       -------

          (f)  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 about my rights and obligations under this Agreement.

                                      -3-
<PAGE>

          (g)  Solicitation of Employees.  I agree that for a period of twelve
               -------------------------
(12) months immediately following the termination of my relationship with the
Company for any reason, whether with or without cause, I shall not either
directly or indirectly solicit, induce, recruit or encourage any of the
Company's employees to leave their employment, or take away such employees, or
attempt to solicit, induce, recruit, encourage or take away employees of the
Company, either for myself or for any other person or entity.

          (h)  Conflict of Interest Guidelines.  I agree to diligently adhere to
               -------------------------------
the Conflict of Interest Guidelines attached as Exhibit D hereto.
                                                ---------

          (i)  Representations.  I agree to execute any proper oath or verify
               ---------------
any proper document required to carry out the terms of this Agreement. I
represent that my performance of all the terms of this Agreement will not breach
any agreement to keep in confidence proprietary 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.

          (j)  Arbitration and Equitable Relief.
               --------------------------------

                (i)  Arbitration.  Except as provided in Section 10(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 Francisco 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.

                (ii) 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 of such Sections, 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.

          (k)  General Provisions.
               ------------------

                (i)  Governing Law; Consent to Personal Jurisdiction.  This
                     -----------------------------------------------
Agreement will be governed by the laws of the State of California. I hereby
expressly consent to the personal jurisdiction of the state and federal courts
located in California for any lawsuit filed there against me by the Company
arising from or relating to this Agreement.

                                      -4-
<PAGE>

               (ii)  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 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.

               (iii) 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.

               (iv)  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.

                      CALIFORNIA LABOR CODE SECTION 2870

                  EMPLOYMENT AGREEMENTS; ASSIGNMENT OF RIGHTS

          (l)  "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.

               (ii) Result from any work performed by the employee for the
employer.

          (m)  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."

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

                              INVENTA CORPORATION

                        CONFLICT OF INTEREST GUIDELINES

     It is the policy of 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.

          (n)  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.)

          (o)  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.

          (p)  Participating in civic or professional organizations that might
involve divulging confidential information of the Company.

          (q)  Initiating or approving personnel actions affecting reward or
punishment of employees or applicants where there is a family relationship or is
or appears to be a personal or social involvement.

          (r)  Initiating or approving any form of personal or social harassment
of employees.

          (s)  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.

          (t)  Borrowing from or lending to employees, customers or suppliers.

          (u)  Acquiring real estate of interest to the Company.

          (v)  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-
<PAGE>

          (w)  Unlawfully discussing prices, costs, customers, sales or markets
with competing companies or their employees.

          (x)  Making any unlawful agreement with distributors with respect to
prices.

          (y)  Improperly using or authorizing the use of any inventions which
are the subject of patent claims of any other person or entity.

          (z)  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.

                                   ARTICLE I

                 Right of First Refusal on Shareholder Transfer
                 ----------------------------------------------

     1.1  Company Right. If at any time a Shareholder desires (or is required)
          -------------
to sell or transfer in any manner any Shares (as hereinafter defined) pursuant
to the terms of a bona fide offer received from a third party (a "Buyer"), the
Shareholder shall submit a written offer to sell such Shares (the "Offered
Shares") to the Company on terms and conditions, including price, not less
favorable to the Company than those on which the Shareholder proposes to sell
such Offered Shares to Buyer (the "Offer"). The Offer shall disclose the
identity of the Buyer, the number of Offered Shares, the terms of the proposed
sale or transfer and any other material facts relating to the sale or transfer.
Within fifteen (15) days after receipt of the Offer, the Company shall give
notice to the Shareholder of its intent to purchase all or some of the Offered
Shares from the Shareholder on the terms and conditions set forth in the Offer.

     1.2  Preferred Holders' Right. If, for any reason whatsoever, the Company
          ------------------------
shall not exercise its right to purchase all of the Offered Shares as provided
herein, the Company shall promptly provide to the Preferred Holders, written
notice (the "Notice") of same (which shall include a copy of the Offer provided
to the Company pursuant to Section 1.1 hereof), and then the Preferred Holders
shall have the right, for a period of fifteen (15) days from the date of the
Notice to purchase, on a pro rata basis, on the same terms and conditions as are
set forth in the Offer, that portion of the Offered Shares which the Company
shall not have agreed to purchase from the Shareholder (all such remaining
Shares being referred to as the "Remaining Offered Shares"). For purposes of
this Section 1.2, Preferred Holder's pro rata right shall be calculated by
dividing the number of shares of Common Stock issuable upon conversion of
Preferred Stock held by such Preferred Holder by the total number of shares of
Common Stock issuable upon conversion of Preferred Stock held by all Preferred
Holders.

     1.3  Failure to Exercise Rights. In the event that the Company and the
          --------------------------
Preferred Holders, taken together, do not purchase all of the Offered Shares
pursuant to and within the time periods set forth above, any remaining Offered
Shares may be sold or transferred by the Shareholder at any time within 90 days
thereafter, subject to compliance with Article II. Any such sale or transfer
shall be at not less than the price nor upon other terms and conditions, if any,
not more favorable to the Buyer than those specified in the Offer. Any Offered
Shares not sold within such 90-day period shall thereafter again be subject to
the requirements of this Article I. In the event that Shares are sold or
transferred to the Preferred Holders pursuant to this subsection, said Offered
Shares shall no longer be subject to this Agreement.

     1.4  Price. With respect to any Shares to be transferred pursuant to
          -----
Section 1.1 hereof and as to which a price has not been set by the Shareholder
under Section 1.1 hereof, the price per Share shall be a price set by the Board
of Directors of the Company which will reflect the current value of the Shares
in terms of present earnings and future prospects of the Company. The Company
shall notify the Shareholder of the price so determined within fifteen (15) days
after receipt by it of the Offer. If the Shareholder disputes the price as set
by the Board of Directors by giving notice to the

                                      -2-
<PAGE>

Company within ten (10) days after being informed of the price, the price of the
Shares shall be determined by an independent financial analyst selected by the
Board of Directors of the Company, with the cost of such determination to be
divided equally between the Company and the Shareholder. The Board of Directors
shall select such analyst within fifteen (15) days after receipt of notice that
the Shareholder is disputing the price set by the Board of Directors. If the
Board is not notified of any such dispute within such ten (10) day period, the
decision of the Board of Directors as to the purchase price shall be final. Any
time required to determine a purchase price or to resolve a dispute shall be
added to the fifteen (15) day period in which the Company may exercise its right
to purchase the Offered Shares.

     1.5  Transfer of Rights. The right of the Preferred Holders to purchase
          ------------------
Offered Shares hereunder may not be assigned except to a transferee or assignee
who qualifies as a partner, subsidiary or affiliate of one of the Preferred
Holders, or a parent of one of the Preferred Holders, or any entity which has
the same parent corporation as one of the Preferred Holders.

     1.6  Prohibited Transfers. The Shareholder shall not sell, assign,
          --------------------
transfer, pledge, hypothecate, mortgage or dispose of, by gift or otherwise, or
in any way encumber, all or any part of the Shares owned by him during the term
of this Agreement other than in compliance with the terms of this Article I.

     1.7  Definition of "Shares". For purposes of this Article I, the term
          ---------------------
"Shares" shall mean and include all shares of capital stock of the Company owned
by the Shareholder, whether presently held or hereafter acquired.

     1.8  Permitted Transfers. The right of first refusal contained in this
          -------------------
Article I shall not apply to: (a) any transfer of Shares by the Shareholder by
gift or bequest or through inheritance to, or for the benefit of, any family
member; (b) any transfer of Shares by the Shareholder to a trust for the benefit
of any family member; (c) any sale or transfer of Shares to the Company (or any
assignee of the Company) pursuant to the terms of a stock restriction or stock
repurchase agreement (which provides for such sale upon the Shareholder's
termination of employment); (d) any sale of Common Stock in a public offering
pursuant to a registration statement filed by the Company with the Securities
and Exchange Commission; (e) any pledge made pursuant to a bona fide loan
transaction that creates a mere security interest; (f) any transfer of Shares by
a Shareholder that is a partnership to its partners; or (g) any transfer of
Shares by a Shareholder that is a trust to a successor trust or successor
trustee. In the event of any transfer pursuant to (a), (b), (f) or (g), the
transferee of the Shares shall hold the Shares so acquired with all the rights
conferred by, and subject to all the restrictions imposed by, this Agreement.

Company and the Preferred Holders do not exercise their right of

                                      -3-
<PAGE>

first refusal as to all of the Offered Shares as set forth in Article I hereof,
each Preferred Holder shall have the right (the "Right of Co-Sale") to require,
as a condition to such sale or transfer, that the Buyer purchase from each
Preferred Holder at the same price per share and on the same terms and
conditions as involved in such sale or disposition by the Shareholder that
percentage of the Offered Shares not purchased by the Company or the Preferred
Holders pursuant to Article I above, expressed by a fraction, the numerator of
which is the number of shares of Preferred Stock (on an as-converted into Common
Stock basis) and Common Stock held by such Preferred Holder and the denominator
of which is the aggregate number of shares of Preferred Stock (on an as-
converted into Common Stock basis) and Common Stock held by all Preferred
Holders and the number of Shares held by the Shareholder. The Preferred Holders
shall act upon the Buyer's offer to buy as soon as practicable after receipt
from the Company of the Notice and in all events within fifteen (15) days after
receipt of the Notice. In the event that the Preferred Holders shall elect to
exercise their Right of Co-Sale, the Preferred Holders shall communicate in
writing such election to the Shareholder.

          -------------------
shall not apply to: (a) any transfer of Shares by the Shareholder by gift or
bequest or through inheritance to, or for the benefit of, any family member; (b)
any transfer of Shares by the Shareholder to a trust for the benefit of any
family member; (c) any sale or transfer of Shares to the Company pursuant to the

applicable); (d) any sale or transfer of Shares to the Company or the Preferred
Holders pursuant to the provisions of Article I hereof; (e) any sale of Common
Stock in a public offering pursuant to a registration statement filed by the
Company with the Securities and Exchange Commission; (f) any pledge made
pursuant to a bona fide loan transaction that creates a mere security interest;

imposed by, this Agreement.

     2.5. Prohibited Transfers.
          --------------------

          (a) In the event that the Shareholder should sell any Shares in
contravention of the co-sale rights of each Preferred Holder under this
Agreement (a "Prohibited Transfer"), each Preferred Holder, in addition to such
other remedies as may be available at law, in equity or hereunder, shall have
the put option provided below, and such Shareholder shall be bound by the
applicable provisions of such option.

                                      -4-
<PAGE>

     (b)  In the event of a Prohibited Transfer, each Preferred Holder shall
have the right to sell to such Shareholder the type and number of shares of
Common Stock equal to the number of shares each Preferred Holder would have been
entitled to transfer to the Buyer under Section 2.1 hereof had the Prohibited
Transfer been effected pursuant to and in compliance with the terms hereof. Such
sale shall be made on the following terms and conditions:

          (i)   The price per share at which the shares are to be sold to the
Shareholder shall be equal to the price per share paid by the Buyer to such
Shareholder in such Prohibited Transfer. The Shareholder shall also reimburse
each Preferred Holder for any and all fees and expenses, including legal fees
and expenses, incurred pursuant to the exercise or the attempted exercise of the
Preferred Holder's rights under this Article II.

          (ii)  Within ninety (90) days after the date on which a Preferred
Holder received notice of the Prohibited Transfer or otherwise became aware of
the Prohibited Transfer, such Preferred Holder shall, if exercising the option
created hereby, deliver to the Shareholder the certificate or certificates
representing the shares to be sold, each certificate to be properly endorsed for
transfer.

          (iii) Such Shareholder shall, upon receipt of the certificate or
certificates for the shares to be sold by a Preferred Holder, pursuant to this
Section 2.5(b), pay the aggregate purchase price therefor and the amount of
reimbursable fees and expenses, as specified in Section 2.5(b)(i), in cash or by
other means acceptable to the Preferred Holder.

          (iv)  Notwithstanding the foregoing, any attempt by the Shareholder to
transfer Shares in violation of Article II hereof shall be voidable at the
option of a majority in interest of the Preferred Holders if the Preferred
Holders do not elect to exercise the put option set forth in this Section 2.5,
and the Company agrees it will not effect such a transfer nor will it treat any
alleged transferee as the holder of such shares without the written consent of a
majority in interest of the Preferred Holders.

and stating therein the quantity of New Securities to be purchased and

Shareholders shall not be transferred except upon the conditions specified in
this Agreement, which conditions are intended to insure compliance with the
provisions of the Securities Act or, in the case of Section 16 hereof, to assist
in an orderly distribution. Each Shareholder will cause any proposed transferee
of Restricted Securities held by that Shareholder to agree to take and hold
those securities subject to the provisions and upon the conditions specified in
this Agreement.
<PAGE>

     3.   Restrictive Legend. Each certificate representing (i) the Shares, and
          ------------------
 (ii) shares of the Company's Common Stock issued upon conversion of the Shares,
 and (iii) any other securities issued in respect of the Shares, or the Common
 Stock issued upon conversion of the Shares, upon any stock split, stock
 dividend, recapitalization, merger, consolidation or similar event, shall
 (unless otherwise permitted or unless the securities evidenced by such
 certificate shall have been registered under the Securities Act) be stamped or
 otherwise imprinted with a legend substantially in the following form (in
 addition to any legend required under applicable state securities laws):

          THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
          INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
          1933, AS AMENDED, (THE "ACT") OR ANY STATE SECURITIES LAWS.  SUCH
          SHARES MAY NOT BE SOLD OR OFFERED FOR SALE IN THE ABSENCE OF SUCH
          REGISTRATION OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY AND
          ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED UNDER THE ACT.
          COPIES OF THE AGREEMENT COVERING THE PURCHASE OF THESE SHARES AND
          RESTRICTING THEIR TRANSFER MAY BE OBTAINED AT NO COST BY WRITTEN
          REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE
          SECRETARY OF THE CORPORATION AT THE PRINCIPAL EXECUTIVE OFFICE OF THE
          CORPORATION.

          Upon request of a holder of such a certificate, the Company shall
remove the foregoing legend from the certificate or issue to such holder a new
certificate therefor free of any transfer legend, if, with such request, the
Company shall have received either the opinion referred to in Section 4(i) or
the "no-action" letter referred to in Section 4(ii) to the effect that any
transfer by such holder of the securities evidenced by such certificate will not
violate the Securities Act and applicable state securities laws, unless any such
transfer legend may be removed pursuant to Rule 144(k), in which case no such
opinion or "no-action" letter shall be required, and provided that the Company
shall not be obligated to remove any such legends prior to the date of the
initial public offering of the Company's Common Stock under the Securities Act.

     4.   Notice of Proposed Transfers. The holder of each certificate
          ----------------------------
representing Restricted Securities by acceptance thereof agrees to comply in all
respects with the provisions of this Section 4. Prior to any proposed transfer
of any Restricted Securities (other than under circumstances described in
Sections 5, 6 and 8 hereof), the holder thereof shall give written notice to the
Company of such holder's intention to effect such transfer. Each such notice
shall describe the manner and circumstances of the proposed transfer in
sufficient detail, and shall be accompanied (except in transactions in
compliance with Rule 144 promulgated under the Securities Act or for a transfer
to a holder's spouse, ancestors, descendants or a trust for any of their
benefit, or in transactions involving the distribution without consideration of
Restricted Securities by a holder that is a partnership to any of its partners
or retired partners or to the estate of any of its partners or retired partners,
or by a holder that is a trust to any successor trust or successor trustee) by
either (i) a written opinion of legal counsel to the holder who shall be
reasonably satisfactory to the Company, addressed to the Company and reasonably
satisfactory in form and substance to the Company's counsel, to the effect that
the proposed transfer of the Restricted Securities may be effected without
registration under the Securities Act or (ii) a "no-action" letter from the
Commission to the effect
<PAGE>

that the distribution of such securities without registration will not result in
a recommendation by the staff of the Commission that action be taken with
respect thereto, whereupon the holder of such Restricted Securities shall be
entitled to transfer such Restricted Securities in accordance with the terms of
the notice delivered by such holder to the Company. Each certificate evidencing
the Restricted Securities transferred as above provided shall bear the
restrictive legend set forth in Section 3 above, except that such certificate
shall not bear such restrictive legend after the date of the Company's initial
public offering under the Securities Act if the opinion of counsel or "no-
action" letter referred to above expressly indicates that such legend is not
required in order to establish compliance with the Securities Act or if such
legend is no longer required pursuant to Rule 144(k).

     5.   Demand Registration.
          -------------------

          (a)  Request for Registration. If the Company shall receive from
               ------------------------
Initiating Holders a written request that the Company effect any registration
with respect to the Registrable Securities, the Company will:

               (i)  promptly given written notice of the proposed registration
to all other Holders; and

               (ii) as soon as practicable, use its diligent best efforts to
effect such registration after January 1, 2000 (including, without limitation,
the execution of an undertaking to file post effective amendments, appropriate
qualification under applicable blue sky or other state securities laws and
appropriate compliance with applicable regulations issued under the Securities
Act) as may be so requested and as would permit or facilitate the sale and
distribution of all or such portion of such Registrable Securities as are
specified in such request, together with all or such portion of the Registrable
Securities of any Holder or Holders joining in such request as are specified in
a written request delivered to the Company within fifteen (15) days after
receipt of such written notice from the Company; provided that the Company shall
not be obligated to effect, or to take any action to effect, any such
registration pursuant to this Section 5:

                    (A) In any particular jurisdiction in which the Company
would be required to execute a general consent to service of process in
effecting such registration, qualification or compliance, unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act;

                    (B) After the Company has effected two (2) such
registrations pursuant to this Section 5(a) and such registrations have been
declared or ordered effective, or withdrawn at the request of the majority of
the Initiating Holders, and the sales of such Registrable Securities have
closed; or

                    (C) Within one hundred eighty (180) days of the effective
date of any other registration statement on Form S-1.

          Subject to the foregoing clauses (A), (B) and (C), the Company shall
file a registration statement covering the Registrable Securities so requested
to be registered as soon as practicable, after receipt of the request or
requests of the Initiating Holders; provided, however, that
<PAGE>

if the Company shall furnish to such Holders a certificate signed by the
President of the Company stating that in the good faith judgment of the Board of
Directors of the Company, it would be seriously detrimental to the Company and
its shareholders for such registration statement to be filed on or before the
time filing would be required and it is therefore essential to defer the filing
of such registration statement, the Company shall have the right to defer such
filing (but not more than once during any twelve month period) for a period of
not more than ninety (90) days after receipt of the request of the Initiating
Holders.

          The registration statement filed pursuant to the request of the
Initiating Holders, may, subject to the provisions of Section 5(b) below,
include other securities of the Company which are held by officers or directors
of the Company or which are held by persons who, by virtue of agreements with
the Company, are entitled to include their securities in any such registration,
but the Company shall have no right to include any of its securities in any such
registration except as provided in Section 5(b) below.

          (b)  Underwriting.  If the Initiating Holders intend to distribute the
               ------------
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
Section 5, and the Company shall include such information in the written notice
referred to in Section 5(a)(i) above.  The right of any Holder to registration
pursuant to Section 5 shall be conditioned upon such Holder's participation in
such underwriting and the inclusion of such Holder's Registrable Securities in
the underwriting (unless otherwise mutually agreed by a majority-in-interest of
the Initiating Holders and such Holder with respect to such participation and
inclusion) to the extent provided herein.  A Holder may elect to include in such
underwriting all or a part of the Registrable Securities he holds.

          If officers or directors of the Company shall request inclusion of
securities of the Company other than Registrable Securities in any registration
pursuant to Section 5, or if holders of securities of the Company who are
entitled by contract with the Company to have securities included in such a
registration (such officers, directors, and other shareholders being
collectively referred to as the "Other Shareholders") request such inclusion,
the Initiating Holders shall, on behalf of all Holders, offer to include the
securities of such Other Shareholders in the underwriting and may condition such
offer on their acceptance of the further applicable provisions of this
Agreement. The Company shall (together with all Holders and Other Shareholders
proposing to distribute their securities through such underwriting) enter into
an underwriting agreement in customary form with the representative of the
underwriter or underwriters (the "Underwriter") selected for such underwriting
by more than fifty percent (50%) of the Initiating Holders and reasonably
acceptable to the Company. Notwithstanding any other provision of this Section
5, if the Underwriter determines that marketing factors require a limitation on
the number of shares to be underwritten, the Underwriter may (subject to the
allocation priority set forth below) limit the number of Registrable Securities
to be included in the registration and underwriting to not less than fifty
percent (50%) of the securities which Holders have requested be included
therein. The Company shall so advise all holders of securities requesting
registration, and the number of shares of securities that are entitled to be
included in the registration and underwriting shall be allocated in the
following priority: first, among all Holders of Registrable Securities
requesting inclusion (and pro rata among such holders on the basis of all
Registrable Securities then held by such holders); and second, among all Other
Shareholders in proportion, as nearly as practicable, to the respective amounts
of securities which
<PAGE>

they had requested to be included in such registration at the time of filing the
registration statement. If any Holder or Other Shareholder disapproves of the
terms of any such underwriting, such holder may elect to withdraw therefrom by
written notice to the Company and the Underwriter. Any Registrable Securities
excluded or withdrawn from such underwriting shall be withdrawn from such
registration. If the Underwriter has not limited the number of Registrable
Securities or other securities to be underwritten, the Company may include its
securities for its own account in such registration if the underwriter so agrees
and if the number of Registrable Securities and other securities which would
otherwise have been included in such registration and underwriting will not
thereby be limited.

     6.   Company Registration.
          --------------------

          (a)  If the Company shall determine to register any of its securities
either for its own account or for the account of a security holder or holders
exercising their respective demand registration rights, other than a
registration relating solely to employee benefit plans or a registration
relating solely to a Commission Rule 145 transaction or a registration on any
registration form which does not permit secondary sales or does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of Registrable Securities, the Company
will:

               (i)  promptly give to each Holder written notice thereof (which,
to the extent then known, shall include a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under the applicable blue
sky or other state securities laws); and

               (ii) include in such registration (and any related qualification
under blue sky laws or other compliance), and in any underwriting involved
therein, all of the Registrable Securities specified in a written request or
requests made by any Holder within fifteen (15) days after receipt of the
written notice from the Company described in clause (i) above, except as set
forth in Section 6(b) below. Such written request may specify all or a part of a
Holder's Registrable Securities.

          (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 a part of the written notice given
pursuant to Section 6(a)(i). In such event the right of any Holder to
registration pursuant to Section 6 shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of such Holder's
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 Shareholders distributing their
securities through such underwriting) enter into an underwriting agreement in
customary form with the Underwriter selected for underwriting by the Company.
Notwithstanding any other provision of this Section 6, if the Underwriter
determines that marketing factors require a limitation on the number of shares
to be underwritten, and (a) if such registration is the first registered
offering of the Company's securities to the public, the Underwriter may (subject
to the allocation priority set forth below) exclude from such registration and
underwriting some or all of the Registrable Securities which would otherwise be
underwritten pursuant hereto, and (b) if such registration is other than the
first registered offering of the sale of the Company's securities to the public,
the Underwriter may
<PAGE>

(subject to the allocation priority set forth below) limit the number of
Registrable Securities to be included in the secondary portion of the
registration and underwriting to not less than fifty percent (50%) of the
securities which Holders have requested be included therein. The Company shall
so advise all holders of securities requesting registration, and the number of
shares of securities that are entitled to be included in the registration and
underwriting by persons other than the Company shall be allocated in the
following priority: first, to Holders of Registrable Securities (and pro rata
among such holders on the basis of all Registrable Securities then held by such
holders); and second, among all Other Shareholders in proportion, as nearly as
practicable, to the respective amounts of securities which they had requested to
be included in such registration at the time of filing the registration
statement. If any Holder or Other Shareholder disapproves of the terms of any
such underwriting, he may elect to withdraw therefrom by written notice to the
Company and the Underwriter. Any Registrable Securities or other securities
excluded or withdrawn from such underwriting shall be withdrawn from such
registration.

     7.   Expenses of Registration.  All Registration Expenses incurred in
          ------------------------
connection with any registration, qualification or compliance pursuant to this
Agreement shall be borne by the Company, and all Selling Expenses shall be borne
by the holders of the securities so registered pro rata on the basis of the
number of their shares so registered; provided, however, that the Company shall
not be required to pay any Registration Expenses if, as a result of the
withdrawal of a request for registration by Initiating Holders, the registration
statement does not become effective, unless such withdrawal is caused by a
material adverse change in the business or operations of the Company after such
request for registration, or unless the Initiating Holders agree to have such
registration considered a registration pursuant to Section 5(a)(ii)(B). If the
Company is not required to pay any Registration Expenses, then the Holders and
Other Shareholders requesting registration shall bear such Registration Expenses
pro rata on the basis of the number of their shares so included in the
registration request, and such registration shall not be considered a
registration for purposes of Section 5(a)(ii)(B).

     8.   Registration on Form S-3.  The Company shall use its best efforts to
          ------------------------
qualify for registration on Form S-3, and to that end, the Company shall comply
with the reporting requirements of the Exchange Act following the effective date
of the first registration of any securities of the Company for a registered
public offering. After the Company has qualified for the use of Form S-3,
Initiating Holders shall have the right to request four (4) registrations on
Form S-3 (such requests shall be in writing and shall state the number of shares
of Registrable Securities to be disposed of and the intended method of
disposition of such shares by each such holder), subject only to the following
limitations:

          (a)  The Company shall not be obligated to cause a registration on
Form S-3 to become effective prior to one hundred eighty (180) days following
the effective date of a Company-initiated registration (other than a
registration effected solely to qualify an employee benefit plan or to effect a
business combination pursuant to Rule 145), provided that notice of such
Company-initiated registration is given to Holders prior to receipt of a request
from a holder of Registrable Securities for registration on Form S-3, and
provided that the Company shall use its best efforts to achieve such
effectiveness promptly following such one hundred eighty (180) day period;
<PAGE>

          (b)  The Company shall not be obligated to cause a registration on
Form S-3 to become effective prior to expiration of one hundred eighty (180)
days following the effective date of the most recent registration pursuant to a
request by a holder of Registrable Securities under this Agreement or pursuant
to a request by a holder of registration rights under any other agreement of the
Company granting Form S-3 demand registration rights; provided, however, that
the Company shall use its best efforts to achieve such effectiveness promptly
following such one hundred eighty (180) day period;

          (c)  The Company shall not be required to effect a registration
pursuant to this Section 8 more than once in any twelve (12) month period;

          (d)  The Company shall not be required to maintain and keep any such
registration on Form S-3 effective for a period exceeding one hundred eighty
(180) days from the effective date thereof. The Company shall give notice to all
Holders and all holders of registration rights under any other agreement of the
Company granting Form S-3 or similar demand registration rights of the receipt
of a request for registration pursuant to this Section 8 and shall provide a
reasonable opportunity for all such other holders to participate in the
registration. Subject to the foregoing, the Company will use its best efforts to
effect promptly the registration of all shares of Registrable Securities on Form
S-3 to the extent requested by the Holder or Holders thereof for purposes of
disposition. In the event the Underwriter, in the case of an underwritten
offering, determines that market factors require a limitation on the number of
shares to be underwritten, then shares shall be excluded from such registration
and underwriting pursuant to the method described in Section 6(b); and

          (e)  The value of the aggregate shares of Registrable Securities to be
registered on Form S-3 for each such right of registration shall be at least
$500,000.

     9.   Registration Procedures. In the case of each registration effected by
          -----------------------
the Company pursuant to this Agreement, the Company will keep each Holder
advised in writing as to the initiation of such registration and as to the
completion thereof. At its expense, the Company will:

          (a)  Keep such registration effective for a period of ninety (90) days
(except as set forth in Section 8(d)) or until the Holder or Holders have
completed the distribution described in the registration statement relating
thereto, whichever first occurs; and

          (b)  Furnish such number of prospectuses and other documents incident
thereto as a Holder from time to time may reasonably request; and

          (c)  In connection with any underwritten offering pursuant to a
registration statement filed pursuant to Section 5 or 8 hereof, the Company will
enter into any underwriting agreement reasonably necessary to effect the offer
and sale of Common Stock, provided such underwriting agreement contains
customary underwriting provisions, and provided further that if the underwriter
so requests the underwriting agreement will contain customary indemnification
and contribution provisions, and provided further that the Underwriter is
reasonably acceptable to the Company.
<PAGE>

      10. Indemnification.
          ---------------

          (a)  The Company will indemnify each Holder, each of its officers,
directors and partners, and each person controlling such Holder, if Registrable
Securities held by such Holder are included in the securities with respect to
which registration, qualification or compliance has been effected pursuant to
this Agreement, and each underwriter, if any, and each person who controls any
underwriter, against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any prospectus, offering
circular or other document (including any related registration statement,
notification or the like) incident to any such registration, qualification or
compliance, or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading,
or any violation by the Company of the Securities Act including any rule or
regulation thereunder applicable to the Company relating to action or inaction
required of the Company in connection with any such registration, qualification
or compliance, and will reimburse each such Holder, each of its officers,
directors and partners, and each person controlling such Holder, each such
underwriter and each person who controls any such underwriter, for any legal and
any other expenses reasonably incurred in connection with investigating and
defending any such claim, loss, damage, liability or action, provided that the
Company will not be liable in any such case to the extent that any such claim,
loss, damage, liability or expense arises out of or is based on any untrue
statement (or alleged untrue statement) or omission (or alleged omission) based
upon written information furnished to the Company by such Holder or underwriter
and stated to be specifically for use therein.

          (b)  Each Holder will, if Registrable Securities or other securities
held by such Holder are included in the securities as to which such
registration, qualification or compliance is being effected, indemnify the
Company, each of its directors, officers and agents and each underwriter, if
any, of the Company's securities covered by such a registration statement, each
person who controls the Company or such underwriter within the meaning of the
Securities Act and the rules and regulations thereunder, each other such Holder
and each of their officers, directors and partners, and each person controlling
such Holder, against all claims, losses, damages and liabilities (or actions in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any such registration
statement, prospectus, offering circular or other document, or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances in
which they were made, not misleading, and will reimburse the Company and such
Holders, directors, officers, agents, partners, persons, underwriters or control
persons for any legal or any other expenses reasonably incurred in connection
with investigating or defending any such claim, loss, damage, liability or
action, in each case to the extent, but only to the extent, that such untrue
statement (or alleged untrue statement) or omission (or alleged omission) is
made in such registration statement, prospectus, offering circular or other
document in reliance upon and in conformity with written information furnished
to the Company by such Holder and stated to be specifically for use therein;
provided, however, that the obligations of such Holders hereunder shall be
limited to an amount equal to the net proceeds to each such Holder of securities
sold as contemplated herein.
<PAGE>

          (c)  Each party entitled to indemnification under this Section 10 (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought and shall
permit the Indemnifying Party to assume the defense of any such claim or any
litigation resulting therefrom, provided that counsel for the Indemnifying
Party, who shall conduct the defense of such claim or any litigation resulting
therefrom, shall be approved by the Indemnified Party (whose approval shall not
unreasonably be withheld), and the Indemnified Party may participate in such
defense at such party's expense, and provided further that the failure of any
Indemnified Party to give notice as provided herein shall not relieve the
Indemnifying Party of its obligations under this Agreement. An indemnified
party shall have the right to retain its own 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.  No
Indemnifying Party in the defense of any such claim or litigation shall, except
with the consent of each Indemnified Party, consent to entry of any judgment or
enter into any settlement which does not include as an unconditional term
thereof the giving by the claimant or plaintiff to such Indemnified Party of a
release from all liability in respect to such claim or litigation.  Each
Indemnified Party shall furnish such information regarding itself or the claim
in question as an Indemnifying Party may reasonably request in writing and as
shall be reasonably required in connection with defense of such claim and
litigation resulting therefrom.

          (d)  If the indemnification provided for in this Section 10 is held by
a court of competent jurisdiction to be unavailable to an indemnified party with
respect to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the extent permitted by applicable law contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability 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 any untrue or alleged untrue statement of a material fact or
the omission to state a material fact that resulted in such loss, claim, damage
or liability, as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by a court of law 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;
provided, that in no event shall any contribution by a Holder thereunder exceed
the proceeds from the offering received by such Holder.

          (e)  The obligations of the Company and Holders under this Section 10
shall survive completion of any offering of Registrable Securities in a
registration statement and the termination of this agreement.

     11.  Information by Holder. Each Holder holding securities included in any
          ---------------------
registration shall furnish to the Company such information regarding such Holder
as the Company may reasonably request in writing and as shall be reasonably
required in connection with any registration, qualification or compliance
referred to in this Agreement.
<PAGE>

     12.  Limitations on Registration of Issues of Securities.  From and after
          ---------------------------------------------------
the date of this Agreement, the Company shall not enter into any agreement with
any holder or prospective holder of any securities of the Company giving such
holder or prospective holder the right to require the Company to initiate any
registration of any securities of the Company, provided that this Section 12
shall not limit the right of the Company to enter any agreements with any holder
or prospective holder of any securities of the Company giving such holder or
prospective holder the right to require the Company, upon any registration of
any of its securities, to include, among the securities which the Company is
then registering, securities owned by such holder. Any right given by the
Company to any holder or prospective holder of the Company's securities in
connection with the registration of securities shall be conditioned such that it
shall be consistent with the provisions of this Agreement and with the rights of
the Holders provided in this Agreement.

     13.  Rule 144 Reporting.  With a view to making available the benefits of
          ------------------
certain rules and regulations of the Commission which may permit the sale of the
Restricted Securities to the public without registration, the Company agrees to:

          (a)  Make and keep public information available as those terms are
understood and defined in Rule 144 under the Securities Act, at all times from
and after ninety (90) days following the effective date of the first
registration under the Securities Act filed by the Company for an offering of
its securities to the general public;

          (b)  Use its best efforts to file with the Commission in a timely
manner all reports and other documents required of the Company under the
Securities Act and the Exchange Act at any time after it has become subject to
such reporting requirements;

          (c)  So long as a Shareholder owns any Restricted Securities, furnish
to the Shareholder forthwith upon request a written statement by the Company as
to its compliance with the reporting requirements of Rule 144 (at any time from
and after ninety (90) days following the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents so filed as a Shareholder may reasonably request in availing itself of
any rule or regulation of the Commission allowing a Shareholder to sell any such
securities without registration.

     14.  No-Action Letter or Opinion of Counsel in Lieu of Registration.
          --------------------------------------------------------------
Notwithstanding anything in this Agreement to the contrary, if at any time after
the date of the Company's initial public offering of its securities under the
Securities Act the Company shall have obtained from the Commission a "no-action"
letter in which the Commission has indicated that it will take no action if,
without registration under the Securities Act, any Holder disposes of
Registrable Securities covered by any request for registration made under this
Agreement in the manner in which such Holder proposes to dispose of the
Registrable Securities included in such request, or if in the opinion of counsel
for the Company concurred in by counsel for such Holder no registration under
the Securities Act is required in connection with such disposition, the
Registrable Securities included in such request shall not be eligible for
registration under this Agreement; provided, however, with respect to any Holder
who may deemed to be an "affiliate," as that term is defined under Rule 144,
<PAGE>

if, notwithstanding the opinion of such counsel, the Holder is unable to dispose
of all of the Registrable Securities included in his request in the manner in
which such Holder so proposes without registration, the Registrable Securities
included in such request shall be eligible for registration under this
Agreement.

     15.  Transfer or Assignment of Registration Rights.  The rights to cause
          ---------------------------------------------
the Company to register a Shareholder's securities granted to such Shareholder
by the Company under Sections 5, 6 and 8 hereof may be transferred or assigned
by the Shareholder to a transferee or assignee of at least 100,000 shares of the
Restricted Securities; provided, however, that a Shareholder may transfer or
assign such rights to a partner or shareholder of Shareholder or to a successor
trust or successor trustee without restriction as to minimum shareholding. The
Company shall be given written notice by Shareholder at the time of said
transfer or assignment, stating the name and address of said transferee or
assignee and identifying the securities with respect to which such registration
rights are being transferred or assigned, and provided further that the
transferee or assignee of such rights is not deemed by the Board of Directors of
the Company, in its reasonable judgment, to be a competitor of the Company; and
provided further that the transferee or assignee of such rights assumes the
obligations of a Shareholder under this Agreement.

     16.  "Market Stand-off" Agreement. Each Shareholder agrees, if requested by
           ---------------------------
the Company and an underwriter of Common Stock (or other securities) of the
Company, not to sell or otherwise transfer or dispose of any Common Stock (or
other securities) of the Company held by Shareholder during a period of time
determined by the Company and its underwriters (not to exceed 180 days)
following the effective date of the Company's initial public offering of its
capital stock, provided that all officers, directors and employees of the
Company holding stock or stock options of at least one (1%) percent of the
Company's outstanding stock prior to the initial public offering of the Company
enter into similar agreements; provided, further, that with respect to the
Series C Holders and Series D Holders, the prohibition against the sale,
transfer or other dispostions of any Common Stock (or other securities) of the
Company held by them pursuant to this Section 16 shall not prohibit (i) the sale
of any shares of Common Stock purchased by such Series C Holder or Series D
Holder pursuant to a directed share program or otherwise in the Company's
initial public offering, or (ii) the sale, in the open market, of any shares of
Common Stock by such Series C Holder or Series D Holder provided that such
shares are purchased in the open market after the completion of the Company's
initial public offering.

          Such agreement shall be in writing in a form satisfactory to the
Company and such underwriter. The Company may impose stop-transfer instructions
with respect to the Shares (or securities) subject to the foregoing restriction
until the end of said period.

     17.  Governing Law.  This Agreement and the legal relations between the
          -------------
parties arising hereunder shall be governed by and interpreted in accordance the
laws of the State of California. The parties hereto agree to submit to the
jurisdiction of the federal and state courts of the State of California with
respect to the breach or interpretation of this Agreement or the enforcement of
any and all rights, duties, liabilities, obligations, powers, and other
relations between the parties arising under this Agreement.
<PAGE>

     18.  Entire Agreement.  This Agreement constitutes the full and entire
          ----------------
understanding and agreement between the parties regarding rights to
registration. Except as otherwise expressly provided herein, the provisions
hereof shall inure to the benefit of, and be binding upon, the successors,
assigns, heirs, executors and administrators of the parties hereto.

     19.  Notices, Etc. All notices and other communications required or
          -------------
permitted hereunder shall be in writing and shall be mailed by first-class mail,
postage prepaid, or otherwise delivered by hand or by messenger, addressed (a)
if to a Shareholder, at the address or addresses set forth on Exhibit A, Exhibit
                                                              ---------  -------
B, Exhibit C, Exhibit C attached hereto, or at such other address or addresses
- -  ---------  ---------
as the Shareholder shall have furnished to the other parties hereto in writing,
or (b) if to any other holder of any securities, at such address as such holder
shall have furnished the other parties hereto in writing, or, until any such
holder so furnishes an address to the Company, then to and at the address of the
last holder of such Shares who has so furnished an address to the Company, or
(c) if to the Company, at the address of its principal offices set forth on the
signature page of this Agreement, or at such other address as the Company shall
have furnished to the other parties hereto in writing.

     20.  Other Registration Rights.  This Agreement supersedes any previous
          -------------------------
  agreement between the Company and any party with respect to the grant by the
Company of registration rights, including but not limited to Registration Rights
                       Agreement dated February 14, 1997.

     21.  Counterparts.  This Agreement may be executed in any number of
          ------------
counterparts, each of which shall be an original, but all of which together
shall constitute one instrument.

     22.  Amendments.  Any provision of this Agreement may be amended, waived or
          ----------
modified upon the written consent of the Company, and the Shareholders (or their
assignees to whom Shareholders have expressly assigned their rights in
compliance with Section 15 hereof) who then hold more than fifty percent (50%)
of the Registrable Securities then held by persons entitled to registration
rights hereunder, provided further, any such amendment, waiver or modification
applies by its terms to each applicable Shareholder and each such assignee and,
provided further, that a Shareholder or such assignee hereunder may waive any of
such Holder's rights or the Company's obligations hereunder without obtaining
the consent of any other Shareholder or assignee.

               (Remainder of this page left intentionally blank)

            To:  Each Investor listed on
                 the Schedule of Investors
                 to the Inventa Corporation
                 Series D Convertible Preferred
                 Stock Purchase Agreement

[LOGO]

            Ladies and Gentlemen:

                 Reference is made to the Series D Convertible Preferred Stock
PALO ALTO   Purchase Agreement dated as of January 19, 2000 (the "Purchase
            Agreement"), complete with all listed exhibits thereto, by and among
            Inventa Corporation, a California corporation, (the "Company") and
            each of you, providing for the issuance by the Company to the
            Investors of shares of Series D Preferred Stock of the Company (the
            "Shares"). This opinion is rendered to you in compliance with
KIRKLAND    Section 5.6 of the Purchase Agreement, and all terms used herein
            have the meanings defined for them in the Purchase Agreement unless
            otherwise defined herein.

AUSTIN           We have acted as counsel for the Company in connection with the
            negotiation of the Purchase Agreement and the issuance of the
            Shares. As such counsel, we have made such legal and factual
            examinations and inquiries as we have deemed advisable or necessary
            for the purpose of rendering this opinion. In addition, we have
            examined originals or copies of such corporate records of the
            Company, certificates of public officials and such other documents
            which we consider necessary or advisable for the purpose of
            rendering this opinion. In such examination we have assumed the
            genuineness of all signatures on original documents, the
            authenticity and completeness of all documents submitted to us as
            originals, the conformity to original documents of all copies
            submitted to us and the due execution and delivery of all documents
            (except as to due execution and delivery by the Company) where due
            execution and delivery are a prerequisite to the effectiveness
            thereof.

                 As used in this opinion, the expression "to our knowledge,"
            "known to us" or similar language with reference to matters of fact
            means that, after an examination of documents made available to us
            by the Company, and after inquiries of officers of the Company, but
            without any further independent factual investigation, we find no
            reason to believe that the opinions expressed herein are factually
            incorrect. Further, the expression "to our knowledge," "known to us"
            or similar language with reference to matters of fact refers to the
            current actual knowledge of the attorneys of this firm who have
            worked on matters for the Company. Except to the extent expressly
            set forth herein or as we otherwise believe to be necessary to our
            opinion, we have not undertaken any independent investigation to
            determine the existence or absence of any fact, and no
<PAGE>

            inference as to our knowledge of the existence or absence of any
            fact should be drawn from our representation of the Company or the
            rendering of the opinion set forth below.

                 For purposes of this opinion, we are assuming that you have all
            requisite power and authority, and have taken any and all necessary
            corporate or partnership action, to execute and deliver the Purchase
            Agreement, and we are assuming that the representations and
            warranties made by the Investors in the Purchase Agreement and
            pursuant thereto are true and correct. We are also assuming that
            each Investor has purchased the Shares for value, in good faith and
            without notice of any adverse claims within the meaning of the
            California Uniform Commercial Code.

                 The opinions hereinafter expressed are subject to the following
            qualifications:

                    (a)  We express no opinion as to the effect of applicable
            bankruptcy, insolvency, reorganization, moratorium or other similar
            federal or state laws affecting the rights of creditors;

                    (b)  We express no opinion as to the effect of rules of law
            governing specific performance, injunctive relief or other equitable
            remedies (regardless of whether any such remedy is considered in a
            proceeding at law or in equity);

                    (c)  We express no opinion as to compliance with the anti-
            fraud provisions of applicable securities laws;

                    (d)  We express no opinion as to the enforceability of the
            indemnification provisions of the Registration Rights Agreement to
            the extent the provisions thereof may be subject to limitations of
            public policy and the effect of applicable statutes and judicial
            decisions; and

                    (e)  We are members of the Bar of the State of California
            and we express no opinion as to any matter relating to the laws of
            any jurisdiction other than the federal laws of the United States of
            America and the laws of the State of California. To the extent this
            opinion addresses applicable securities laws of states other than
            the State of California, we have not retained nor relied on the
            opinion of counsel admitted to the bar of such states, but rather
            have relied on compilations of the securities laws of such states
            contained in reporting services presently available to us.

                 Based upon and subject to the foregoing, and except as set
            forth in the Schedule of Exceptions to the Purchase Agreement, we
            are of the opinion that:

                 1. The Company is a corporation duly organized and validly
            existing under, and by virtue of, the laws of the State of
            California and is in good standing under such laws. The Company has
            requisite corporate power to own and operate its properties and
            assets, and to carry on its business as presently conducted. The
            Company is duly qualified to do business, and in good standing in
            all foreign jurisdictions where its ownership or leasing of
            properties or the conduct of its
<PAGE>

Page 3


            business requires such qualification, except where the failure to be
            so qualified would not have a material adverse effect on the
            Company's business as now conducted.

                 2. The Company has all requisite legal and corporate power to
            execute and deliver the Purchase Agreement, the Shareholders
            Agreement, the Registration Rights Agreement and the side letter
            agreement of even date herewith among the Company and the Investors
            listed on Schedule A thereto regarding a proposed private placement
            of common stock (collectively, the "Agreements"), to sell and issue
            the Shares under the Purchase Agreement, to issue the Common Stock
            issuable upon conversion of the Shares and to carry out and perform
            its obligations under the terms of the Agreements.

                 3. The authorized capital of the Company consists of (i)
            14,779,511 shares of Preferred Stock, 1,000,000 shares of which are
            designated Series A Preferred Stock and of which 800,000 are issued
            and outstanding, 2,560,000 shares of which are designated Series B
            Preferred Stock and of which 2,560,000 are issued and outstanding,
            8,219,511 shares of which are designated Series C Preferred Stock
            and of which 8,055,511 are issued and outstanding, and 3,000,000
            shares of which are designated Series D Preferred Stock, none of
            which are issued and outstanding, and (ii) 25,000,000 shares of
            Common Stock, of which 4,713,055 shares are issued and outstanding.
            All issued and outstanding shares of the Company's capital stock
            have been duly authorized and validly issued and are fully paid and
            nonassessable. The Shares, when issued pursuant to the terms of the
            Purchase Agreement (including Common Stock issued upon conversion of
            the Shares), will be duly authorized, validly issued, fully paid and
            nonassessable. Except as set forth in the Agreements and all the
            exhibits thereto, to our knowledge, there are no options, warrants
            or other rights (including conversion or preemptive rights) or
            agreements outstanding to purchase any of the Company's authorized
            and unissued capital stock.

                 4. All corporate action on the part of the Company, its
            directors and shareholders necessary for the authorization,
            execution, delivery and performance of the Agreements, the
            authorization, sale, issuance and delivery of the Shares and the
            performance of the Company's obligations under the Agreements has
            been taken. The Agreements have been duly and validly executed and
            delivered by the Company and constitute valid and binding
            obligations of the Company, enforceable against the Company in
            accordance with their terms. The Shares will have the rights,
            preferences and privileges described in the Restated Articles. To
            our knowledge, the Shares and the Common Stock issuable on
            conversion of the Shares will be free of any liens, encumbrances or
            preemptive rights contained in the Company's Restated Articles or
            Bylaws.

                 5. The execution, delivery and performance of and compliance
            with the terms of the Agreements, and the issuance of the Shares do
            not violate any provision of the Restated Articles or Bylaws, or, to
            our knowledge, any provisions of any applicable federal or state
            law, rule or regulation. To our knowledge, the execution, delivery
            and performance of and compliance with the Agreements and the
            issuance of the Shares do not violate or constitute a default under,
            any material contract, agreement, instrument, judgment or decree
            binding upon the Company.

                 6. To our knowledge, there are no actions, suits, proceedings
            or investigations pending against the Company or its properties
            before any court or governmental agency (nor, to our knowledge, has
            the Company received any written threat thereof), which, either in
            any case or in the aggregate, are likely to result in any material
            adverse change in the business or financial condition of the
            Company, or in any material impairment of the right or ability of
            the Company to carry on its business as now conducted, or which
            questions the validity of the Agreements or any action taken or to
            be taken by the Company in connection therewith.

                 7. No consent, approval or authorization of or designation,
            declaration or filing with any governmental authority on the part of
            the Company is required in connection with the valid execution and
            delivery of the Agreements or other offer, sale or issuance of the
            Shares or the consummation of any other transaction contemplated
            thereby, except (a) filing of the Restated Articles in the Office of
            the Secretary of State of the State of California, and (b)
            qualification (or taking such action as may be necessary to secure
            an exemption from qualification, if available) under the California
            Corporate Securities Law and other applicable blue sky laws (but
            excluding jurisdictions outside of the United States) of the offer
            and sale of the Shares (and the Common Stock issuable upon
            conversion thereof) and the modification of rights of shareholders
            contemplated by the Purchase Agreement. The filing referred to in
            clause (a) above has been accomplished and is effective, and to our
            knowledge there are no proceedings or written threat thereof which
            question the validity of such filing. Our opinion herein is
            otherwise subject to the timely and proper completion of all filings
            and other actions contemplated by clause (b) above where such
            filings and actions are to be undertaken on or after the date
            hereof.

                 8. Subject to the accuracy of each Investor's representations
            in Section 3 of the Purchase Agreement we are of the opinion that
            the offer, sale and issuance of the Shares in conformity with the
            terms of the Purchase Agreement constitute transactions exempt from
            the requirements of Section 5 of the Securities Act of 1933, as
            amended.

                 This opinion is furnished to the Investors solely for their
            benefit in connection with the purchase of the Shares, and may not
            be relied upon by any other person or for any other purpose without
            our prior written consent.


                                        Very truly yours,

                                        WILSON SONSINI GOODRICH & ROSATI
                                        Professional Corporation

             --------
the Plan shall not be returned to the Plan and shall not become available for
future distribution under the Plan, except that if Shares of restricted stock
are repurchased by the Company at their original purchase price, such Shares
shall become available for future grant under the Plan.

        4.  Administration of the Plan.
            --------------------------

            (a)  Procedure.
                 ---------

                        (i)  Multiple Administrative Bodies. Different
                             ------------------------------
Committees with respect to different groups of Service Providers may administer
the Plan.

                                      -3-
<PAGE>

                        (ii)  Section 162(m). To the extent that the
                              --------------
Administrator determines it to be desirable to qualify Options granted hereunder
as "performance-based compensation" within the meaning of Section 162(m) of the
Code, the Plan shall be administrated by a Committee of two or more "outside
directors" within the meaning of Sectiion 162(m) of the Code.

                        (iii)  Rule 16b-3. To the extent desirable to qualify
                               ----------
transactions hereunder as exempt under Rule 16b-3, the transactions contemplated
hereunder shall be structured to satisfy the requirements for exemption under
Rule 16b-3.

                        (iv)   Other Administration. Other than as provided
                               --------------------
above, the Plan shall be administered by (A) the Board or (B) a Committee, which
committee shall be constituted to satisfy Applicable Laws.

             (b)  Powers of the Administrator. Subject to the provisions of the
                  ---------------------------
Plan, and in the case of a Committee, subject to the specific duties delegated
by the Board to such Committee, the Administrator shall have the authority, in
its discretion:

                        (i)  to determine the Fair Market Value;

                       (ii)  to select the Service Providers to whom Options may
be granted hereunder;

                      (iii)  to determine the number of shares of Common Stock
to be covered by each Option granted hereunder;

                       (iv)  to approve forms of agreement for use under the
Plan;

                        (v)  to determine the terms and conditions, not
inconsistent with the terms of the Plan or any Option granted hereunder. Such
terms and conditions include, but are not limited to, the exercise price, the
time or times when Options may be exercised (which may be based on performance
criteria), any vesting acceleration or waiver of forfeiture restrictions, and
any restriction or limitation regarding any Option or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

                       (vi)  to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan;

                      (vii)  to prescribe, amend and rescind rules and
regulations relating to the Plan, including rules and regulations relating to
sub-plans established for the purpose of satisfying applicable foreign laws;

                     (viii)  to modify or amend each Option (subject to Section
14(c) of the Plan), including the discretionary authority to extend the post-
termination exercisability period of Options longer than is otherwise provided
for in the Plan;

                       (ix)  to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option that number of Shares having a Fair Market
Value equal to the amount required to be withheld. The Fair Market

                                      -4-
<PAGE>

Value of the Shares to be withheld shall be determined on the date that the
amount of tax to be withheld is to be determined. All elections by an Optionee
to have Shares withheld for this purpose shall be made in such form and under
such conditions as the Administrator may deem necessary or advisable;

                        (x)  to authorize any person to execute on behalf of the
Company any instrument required to effect the grant of an Option previously
granted by the Administrator;

                       (xi)  to make all other determinations deemed necessary
or advisable for administering the Plan.

            (c)  Effect of Administrator's Decision. The Administrator's
                 ----------------------------------
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options.

        5.  Eligibility.  Nonstatutory Stock Options may be granted to Service
            -----------
Providers.  Incentive Stock Options may be granted only to Employees.

        6.  Limitations.
            -----------

            (a)  Each Option shall be designated in the Option Agreement as
either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options. For purposes of this
Section 6(a), Incentive Stock Options shall be taken into account in the order
in which they were granted. The Fair Market Value of the Shares shall be
determined as of the time the Option with respect to such Shares is granted.

            (b)  Neither the Plan nor any Option shall confer upon an Optionee
any right with respect to continuing the Optionee's relationship as a Service
Provider with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

            (c)  The following limitations shall apply to grants of Options:

                        (i)  No Service Provider shall be granted, in any fiscal
year of the Company, Options to purchase more than [________] Shares.

                        (ii)  In connection with his or her initial service, a
Service Provider may be granted Options to purchase up to an additional
[________] Shares, which shall not count against the limit set forth in
subsection (i) above.

                        (iii)  The foregoing limitations shall be adjusted
proportionately in connection with any change in the Company's capitalization as
described in Section 12.

                        (iv)  If an Option is cancelled in the same fiscal year
of the Company in which it was granted (other than in connection with a
transaction described in Section 12), the

                                      -5-
<PAGE>

cancelled Option will be counted against the limits set forth in subsections (i)
and (ii) above. For this purpose, if the exercise price of an Option is reduced,
the transaction will be treated as a cancellation of the Option and the grant of
a new Option

        7.  Term of Plan. Subject to Section 18 of the Plan, the Plan shall
            ------------
become effective upon its adoption by the Board. It shall continue in effect for
a term of ten (10) years unless terminated earlier under Section 14 of the Plan.

        8.  Term of Option. The term of each Option shall be stated in the
            --------------
Option Agreement. In the case of an Incentive Stock Option, the term shall be
ten (10) years from the date of grant or such shorter term as may be provided in
the Option Agreement. Moreover, in the case of an Incentive Stock Option granted
to an Optionee who, at the time the Incentive Stock Option is granted, owns
stock representing more than ten percent (10%) of the total combined voting
power of all classes of stock of the Company or any Parent or Subsidiary, the
term of the Incentive Stock Option shall be five (5) years from the date of
grant or such shorter term as may be provided in the Option Agreement.

        9.  Option Exercise Price and Consideration.
            ---------------------------------------

            (a)  Exercise Price. The per share exercise price for the Shares to
                 --------------
be issued pursuant to exercise of an Option shall be determined by the
Administrator, subject to the following:

                        (i)  In the case of an Incentive Stock Option

                             (A)  granted to an Employee who, at the time the
Incentive Stock Option is granted, owns stock representing more than ten percent
(10%) of the voting power of all classes of stock of the Company or any Parent
or Subsidiary, the per Share exercise price shall be no less than 110% of the
Fair Market Value per Share on the date of grant.

                             (B)  granted to any Employee other than an Employee
described in paragraph (A) immediately above, the per Share exercise price shall
be no less than 100% of the Fair Market Value per Share on the date of grant.

                        (ii)  In the case of a Nonstatutory Stock Option, the
per Share exercise price shall be determined by the Administrator. In the case
of a Nonstatutory Stock Option intended to qualify as "performance-based
compensation" within the meaning of Section 162(m) of the Code, the per Share
exercise price shall be no less than 100% of the Fair Market Value per Share on
the date of grant.

                        (iii)  Notwithstanding the foregoing, Options may be
granted with a per Share exercise price of less than 100% of the Fair Market
Value per Share on the date of grant pursuant to a merger or other corporate
transaction.

            (b)  Waiting Period and Exercise Dates. At the time an Option is
                 ---------------------------------
granted the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions that must be satisfied before the
Option may be exercised.

                                      -6-
<PAGE>

            (c)  Form of Consideration. The Administrator shall determine the
                 ---------------------
acceptable form of consideration for exercising an Option, including the method
of payment. In the case of an Incentive Stock Option, the Administrator shall
determine the acceptable form of consideration at the time of grant. Such
consideration may consist entirely of:

                        (i)  cash;

                        (ii)  check;

                        (iii)  promissory note;

                        (iv)  other Shares, provided Shares acquired from the
Company (A) 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 aggregate exercise price of the Shares as to which said Option
shall be exercised;

                        (v)  consideration received by the Company under a
cashless exercise program implemented by the Company in connection with the
Plan;

                        (vi)  a reduction in the amount of any Company liability
to the Optionee, including any liability attributable to the Optionee's
participation in any Company-sponsored deferred compensation program or
arrangement;

                        (vii)  any combination of the foregoing methods of
payment; or

                        (viii)  such other consideration and method of payment
for the issuance of Shares to the extent permitted by Applicable Laws.

        10.  Exercise of Option.
             ------------------

             (a)  Procedure for Exercise; Rights as a Shareholder. Any Option
                  -----------------------------------------------
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. Unless the Administrator provides otherwise,
vesting of Options granted hereunder shall be tolled during any unpaid leave of
absence. An Option may not be exercised for a fraction of a Share.

                  An Option shall be deemed exercised when the Company receives:
(i) written or electronic notice of exercise (in accordance with the Option
Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are 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 shareholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a

                                      -7-
<PAGE>

dividend or other right for which the record date is prior to the date the
Shares are issued, except as provided in Section 12 of the Plan.

                Exercising an Option in any manner shall decrease the number of
Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

             (b)  Termination of Relationship as a Service Provider. If an
                  -------------------------------------------------
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option within such period of
time as is specified in the Option Agreement to the extent that the Option is
vested on the date of termination (but in no event later than the expiration of
the term of such Option as set forth in the Option Agreement). In the absence of
a specified time in the Option Agreement, the Option shall remain exercisable
for three (3) months following the Optionee's termination. If, on the date of
termination, the Optionee is not vested as to his or her entire Option, the
Shares covered by the unvested portion of the Option shall revert to the Plan.
If, after termination, the Optionee does not exercise his or her Option within
the time specified by the Administrator, the Option shall terminate, and the
Shares covered by such Option shall revert to the Plan.

             (c)  Disability of Optionee. If an Optionee ceases to be a
                  ----------------------
Service Provider as a result of the Optionee's Disability, the Optionee may
exercise his or her Option within such period of time as is specified in the
Option Agreement to the extent the Option is vested on the date of termination
(but in no event later than the expiration of the term of such Option as set
forth in the Option Agreement). In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee's termination. If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

             (d)  Death of Optionee. If an Optionee dies while a Service
                  -----------------
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant), by the Optionee's estate or
by a person who acquires the right to exercise the Option by bequest or
inheritance, but only to the extent that the Option is vested on the date of
death. In the absence of a specified time in the Option Agreement, the Option
shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall immediately revert to the Plan. The Option may be exercised by the
executor or administrator of the Optionee's estate or, if none, by the person(s)
entitled to exercise the Option under the Optionee's will or the laws of descent
or distribution. If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

        11.  Non-Transferability of Options.  Unless determined otherwise by the
             ------------------------------
Administrator, an Option 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.  If the Administrator makes an Option
transferable,

                                      -8-
<PAGE>

such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

        12.  Adjustments Upon Changes in Capitalization, Dissolution, Merger or
             ------------------------------------------------------------------
Asset Sale.
- ----------

             (a)  Changes in Capitalization. Subject to any required action by
                  -------------------------
the shareholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, the number of shares that may be added annually to the
shares reserved under the Plan (pursuant to Section 3(a)(i)), as well as the
price per share of Common Stock covered by each such outstanding Option, shall
be proportionately adjusted for any increase or decrease in the number of issued
shares of Common Stock resulting from a stock split, reverse stock split, stock
dividend, combination or reclassification of the Common Stock, or any other
increase or decrease in the number of issued shares of Common Stock effected
without receipt of consideration by the Company; provided, however, that
conversion of any convertible securities of the Company shall not be deemed to
have been "effected without receipt of consideration." Such adjustment shall be
made by the Board, whose determination in that respect shall be final, binding
and conclusive. Except as expressly provided herein, no issuance by the Company
of shares of stock of any class, or securities convertible into shares of stock
of any class, shall affect, and no adjustment by reason thereof shall be made
with respect to, the number or price of shares of Common Stock subject to an
Option.

             (b)  Dissolution or Liquidation. In the event of the proposed
                  --------------------------
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

             (c)  Merger or Asset Sale. In the event of a merger of the Company
                  --------------------
with or into another corporation, or the sale of substantially all of the assets
of the Company, each outstanding Option shall be assumed or an equivalent option
or right substituted by the successor corporation or a Parent or Subsidiary of
the successor corporation. In the event that the successor corporation refuses
to assume or substitute for the Option, the Optionee shall fully vest in and
have the right to exercise the Option as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable. If an Option
becomes fully vested and exercisable in lieu of assumption or substitution in
the event of a merger or sale of assets, the Administrator shall notify the
Optionee in writing or electronically that the Option shall be fully vested and
exercisable for a period of fifteen (15) days from the date of such notice, and
the Option shall terminate upon the expiration of such period. For the purposes
of this paragraph, the Option shall be considered assumed if, following the
merger or sale of assets, the option confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option immediately prior to the
merger or sale of

                                      -9-
<PAGE>

assets, the consideration (whether stock, cash, or other securities or property)
received in the merger or sale of assets by holders of Common Stock for each
Share held on the effective date of the transaction (and if holders were offered
a choice of consideration, the type of consideration chosen by the holders of a
majority of the outstanding Shares); provided, however, that if such
consideration received in the merger or sale of assets is not solely common
stock of the successor corporation or its Parent, the Administrator may, with
the consent of the successor corporation, provide for the consideration to be
received upon the exercise of the Option, for each Share of Optioned Stock
subject to the Option, to be solely common stock of the successor corporation or
its Parent equal in fair market value to the per share consideration received by
holders of Common Stock in the merger or sale of assets.

        13.  Date of Grant. The date of grant of an Option shall be, for all
             -------------
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.

        14.  Amendment and Termination of the Plan.
             -------------------------------------

             (a)  Amendment and Termination. The Board may at any time amend,
                  -------------------------
alter, suspend or terminate the Plan.

             (b)  Shareholder Approval. The Company shall obtain shareholder
                  --------------------
approval of any Plan amendment to the extent necessary and desirable to comply
with Applicable Laws.

             (c)  Effect of Amendment or Termination. No amendment, alteration,
                  ----------------------------------
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to Options granted under the
Plan prior to the date of such termination.

        15.  Conditions Upon Issuance of Shares.
             ----------------------------------

             (a)  Legal Compliance. Shares shall not be issued pursuant to the
                  ----------------
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

             (b)  Investment Representations. As a condition to the exercise of
                  --------------------------
an Option, the Company may require the person exercising such Option to
represent and warrant at the time of any such exercise that the Shares are being
purchased only for investment and without any present intention to sell or
distribute such Shares if, in the opinion of counsel for the Company, such a
representation is required.

        16.  Inability to Obtain Authority. The inability of the Company to
             -----------------------------
obtain authority from any regulatory body having jurisdiction, which authority
is deemed by the Company's counsel to be necessary to the lawful issuance and
sale of any Shares hereunder, shall relieve the Company of any

                                      -10-
<PAGE>

liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

        17.  Reservation of Shares. The Company, during the term of this Plan,
             ---------------------
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

        18.  Shareholder Approval. The Plan shall be subject to approval by the
             --------------------
shareholders of the Company within twelve (12) months after the date the Plan is
adopted. Such shareholder approval shall be obtained in the manner and to the
degree required under Applicable Laws.

II.  AGREEMENT
     ---------
     A.  Grant of Option.
         ---------------

          The Plan Administrator of the Company hereby grants to the Optionee

Plan and the terms and conditions of this Option Agreement, the terms and
conditions of the Plan shall prevail.

          If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option under
Section 422 of the Code.  However, if this Option is intended to be an Incentive
Stock Option, to the extent that it exceeds the $100,000 rule of Code Section
422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

     B.  Exercise of Option.
         -------------------

         (a)  Right to Exercise. This Option is exercisable during its term in

respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be completed

accompanied by payment of the aggregate Exercise Price as to all Exercised
Shares. This Option shall be deemed to be exercised upon receipt by the Company
of such fully executed Exercise Notice accompanied by such aggregate Exercise
Price.

              No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws.  Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

     D.  Non-Transferability of Option. This Option may not be transferred in
         -----------------------------
any manner otherwise than by will or by the laws of descent or distribution and

of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

         1.  Withholding Taxes. Optionee agrees to make appropriate arrangements
             -----------------

Employee shall be granted an option under the Plan (i) to the extent that,
immediately after the grant, such Employee (or any other person whose stock
would be attributed to such Employee pursuant to Section 424(d) of the Code)
would own capital stock of the Company and/or hold outstanding options to
purchase such stock possessing five percent (5%) or more of the total combined

                                      -3-
<PAGE>

     6.  Payroll Deductions.
         ------------------

         (a)  At the time a participant files his or her subscription agreement,
he or she shall elect to have payroll deductions made on each pay day during the
Offering Period in an amount not exceeding fifteen percent (15%) of the
Compensation which he or she receives on each pay day during the Offering
Period.

         (b)  All payroll deductions made for a participant shall be credited to
his or her account under the Plan and shall be withheld in whole percentages
only. A participant may not make any additional payments into such account.

         (c)  A participant may discontinue his or her participation in the Plan
as provided in Section 10 hereof, or may increase or decrease the rate of his or
her payroll deductions during the Offering Period by completing or filing with
the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

         (d)  Notwithstanding the foregoing, to the extent necessary to comply
with Section 423(b)(8) of the Code and Section 3(b) hereof, a participant's
payroll deductions may be decreased to zero percent (0%) at any time during a
Purchase Period. Payroll deductions shall recommence at the rate provided in
such participant's subscription agreement at the beginning of the first Purchase
Period which is scheduled to end in the following calendar year, unless
terminated by the participant as provided in Section 10 hereof.

         (e)  At the time the option is exercised, in whole or in part, or at
the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

     7.  Grant of Option.  On the Enrollment Date of each Offering Period, each
         ---------------
eligible Employee participating in such Offering Period shall be granted an
option to purchase on each Exercise Date during such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that in no event shall
an Employee be permitted to purchase during each Purchase Period more than
5,000 shares of the Company's Common Stock (subject to any adjustment
pursuant to Section 19), and provided further that such purchase shall be
subject to the limitations set forth in Sections 3(b) and 12 hereof.  The Board
may, for future Offering Periods, increase or decrease, in its absolute
discretion, the maximum number of shares of

                                      -4-
<PAGE>

the Company's Common Stock an Employee may purchase during each Purchase Period
of such Offering Period. Exercise of the option shall occur as provided in
Section 8 hereof, unless the participant has withdrawn pursuant to Section 10
hereof. The option shall expire on the last day of the Offering Period.

     8.  Exercise of Option.
         ------------------

         (a)  Unless a participant withdraws from the Plan as provided in
Section 10 hereof, his or her option for the purchase of shares shall be
exercised automatically on the Exercise Date, and the maximum number of full
shares subject to option shall be purchased for such participant at the
applicable Purchase Price with the accumulated payroll deductions in his or her
account. No fractional shares shall be purchased; any payroll deductions
accumulated in a participant's account which are not sufficient to purchase a
full share shall be retained in the participant's account for the subsequent
Purchase Period or Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

         (b)  If the Board determines that, on a given Exercise Date, the number
of shares with respect to which options are to be exercised may exceed (i) the
number of shares of Common Stock that were available for sale under the Plan on
the Enrollment Date of the applicable Offering Period, or (ii) the number of
shares available for sale under the Plan on such Exercise Date, the Board may in
its sole discretion (x) provide that the Company shall make a pro rata
allocation of the shares of Common Stock available for purchase on such
Enrollment Date or Exercise Date, as applicable, in as uniform a manner as shall
be practicable and as it shall determine in its sole discretion to be equitable
among all participants exercising options to purchase Common Stock on such
Exercise Date, and continue all Offering Periods then in effect, or (y) provide
that the Company shall make a pro rata allocation of the shares available for
purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform
a manner as shall be practicable and as it shall determine in its sole
discretion to be equitable among all participants exercising options to purchase
Common Stock on such Exercise Date, and terminate any or all Offering Periods
then in effect pursuant to Section 20 hereof. The Company may make pro rata
allocation of the shares available on the Enrollment Date of any applicable
Offering Period pursuant to the preceding sentence, notwithstanding any
authorization of additional shares for issuance under the Plan by the Company's
shareholders subsequent to such Enrollment Date.

     9.  Delivery.  As promptly as practicable after each Exercise Date on
         --------
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of a certificate representing the shares
purchased upon exercise of his or her option.

     10. Withdrawal.
         ----------

         (a)  A participant may withdraw all but not less than all the payroll
deductions credited to his or her account and not yet used to exercise his or
her option under the Plan at any time by giving written notice to the Company in
the form of Exhibit B to this Plan. All of the participant's payroll deductions
credited to his or her account shall be paid to such participant

                                      -5-
<PAGE>

promptly after receipt of notice of withdrawal and such participant's option for
the Offering Period shall be automatically terminated, and no further payroll
deductions for the purchase of shares shall be made for such Offering Period. If
a participant withdraws from an Offering Period, payroll deductions shall not
resume at the beginning of the succeeding Offering Period unless the participant
delivers to the Company a new subscription agreement.

         (b)  A participant's withdrawal from an Offering Period shall not have
any effect upon his or her eligibility to participate in any similar plan which
may hereafter be adopted by the Company or in succeeding Offering Periods which
commence after the termination of the Offering Period from which the participant
withdraws.

     11.  Termination of Employment.
          -------------------------

          Upon a participant's ceasing to be an Employee, for any reason, he or
she shall be deemed to have elected to withdraw from the Plan and the payroll
deductions credited to such participant's account during the Offering Period but
not yet used to exercise the option shall be returned to such participant or, in
the case of his or her death, to the person or persons entitled thereto under
Section 15 hereof, and such participant's option shall be automatically
terminated.  The preceding sentence notwithstanding, a participant who receives
payment in lieu of notice of termination of employment shall be treated as
continuing to be an Employee for the participant's customary number of hours per
week of employment during the period in which the participant is subject to such
payment in lieu of notice.

     12.  Interest.  No interest shall accrue on the payroll deductions of a
          --------
participant in the Plan.

     13.  Stock.
          -----

          (a)  Subject to adjustment upon changes in capitalization of the
Company as provided in Section 19 hereof, the maximum number of shares of the
Company's Common Stock which shall be made available for sale under the Plan
shall be 500,000 shares plus an annual increase to be added on the first day of
the Company's fiscal year beginning in 2001, equal to the lesser of (i) 600,000
shares, (ii) 2% of the outstanding shares on such date or (iii) a lesser amount
determined by the Board.

          (b)  The participant shall have no interest or voting right in shares
covered by his option until such option has been exercised.

          (c)  Shares to be delivered to a participant under the Plan shall be
registered in the name of the participant or in the name of the participant and
his or her spouse.

     14.  Administration.  The Plan shall be administered by the Board or a
          --------------
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

                                      -6-
<PAGE>

     15.  Designation of Beneficiary.
          --------------------------

          (a)  A participant may file a written designation of a beneficiary who
is to receive any shares and cash, if any, from the participant's account under
the Plan in the event of such participant's death subsequent to an Exercise Date
on which the option is exercised but prior to delivery to such participant of
such shares and cash. In addition, a participant may file a written designation
of a beneficiary who is to receive any cash from the participant's account under
the Plan in the event of such participant's death prior to exercise of the
option. If a participant is married and the designated beneficiary is not the
spouse, spousal consent shall be required for such designation to be effective.

          (b)  Such designation of beneficiary may be changed by the participant
at any time by written notice. In the event of the death of a participant and in
the absence of a beneficiary validly designated under the Plan who is living at
the time of such participant's death, the Company shall deliver such shares
and/or cash to the executor or administrator of the estate of the participant,
or if no such executor or administrator has been appointed (to the knowledge of
the Company), the Company, in its discretion, may deliver such shares and/or
cash to the spouse or to any one or more dependents or relatives of the
participant, or if no spouse, dependent or relative is known to the Company,
then to such other person as the Company may designate.

     16.  Transferability.  Neither payroll deductions credited to a
          ---------------
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.

     17.  Use of Funds.  All payroll deductions received or held by the
          ------------
Company under the Plan may be used by the Company for any corporate purpose, and
the Company shall not be obligated to segregate such payroll deductions.

     18.  Reports.  Individual accounts shall be maintained for each
          -------
participant in the Plan. Statements of account shall be given to participating
Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

     19.  Adjustments Upon Changes in Capitalization, Dissolution, Liquidation,
          ---------------------------------------------------------------------
Merger or Asset Sale.
- --------------------

     (a)  Changes in Capitalization.  Subject to any required action by the
          -------------------------
shareholders of the Company, the Reserves, the maximum number of shares each
participant may purchase each Purchase Period (pursuant to Section 7), the
number of shares that may be added annually to the shares reserved under the
Plan (pursuant to Section 13(a)(i)), as well as the price per share and the
number of shares of Common Stock covered by each option under the Plan which has
not yet been exercised shall be proportionately adjusted for any increase or
decrease in the number of issued shares of Common Stock resulting from a stock
split, reverse stock split, stock dividend, combination or reclassification of
the Common Stock, or any other increase or decrease in the

                                      -7-
<PAGE>

number of shares of Common Stock effected without receipt of consideration by
the Company; provided, however, that conversion of any convertible securities of
the Company shall not be deemed to have been "effected without receipt of
consideration." Such adjustment shall be made by the Board, whose determination
in that respect shall be final, binding and conclusive. Except as expressly
provided herein, no issuance by the Company of shares of stock of any class, or
securities convertible into shares of stock of any class, shall affect, and no
adjustment by reason thereof shall be made with respect to, the number or price
of shares of Common Stock subject to an option.

          (b)  Dissolution or Liquidation.  In the event of the proposed
               --------------------------
dissolution or liquidation of the Company, the Offering Period then in progress
shall be shortened by setting a new Exercise Date (the "New Exercise Date"), and
shall terminate immediately prior to the consummation of such proposed
dissolution or liquidation, unless provided otherwise by the Board. The New
Exercise Date shall be before the date of the Company's proposed dissolution or
liquidation. The Board shall notify each participant in writing, at least ten
(10) business days prior to the New Exercise Date, that the Exercise Date for
the participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

          (c)  Merger or Asset Sale.  In the event of a proposed sale of all or
               --------------------
substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, each outstanding option shall be assumed or an
equivalent option substituted by the successor corporation or a Parent or
Subsidiary of the successor corporation. In the event that the successor
corporation refuses to assume or substitute for the option, any Purchase Periods
then in progress shall be shortened by setting a new Exercise Date (the "New
Exercise Date") and any Offering Periods then in progress shall end on the New
Exercise Date. The New Exercise Date shall be before the date of the Company's
proposed sale or merger. The Board shall notify each participant in writing, at
least ten (10) business days prior to the New Exercise Date, that the Exercise
Date for the participant's option has been changed to the New Exercise Date and
that the participant's option shall be exercised automatically on the New
Exercise Date, unless prior to such date the participant has withdrawn from the
Offering Period as provided in Section 10 hereof.

     20.  Amendment or Termination.
          ------------------------

          (a)  The Board of Directors of the Company may at any time and for any
reason terminate or amend the Plan. Except as provided in Section 19 hereof, no
such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Offering Period or the Plan
is in the best interests of the Company and its shareholders. Except as provided
in Section 19 and this Section 20 hereof, no amendment may make any change in
any option theretofore granted which adversely affects the rights of any
participant. To the extent necessary to comply with Section 423 of the Code (or
any successor rule or provision or any other applicable law, regulation or stock
exchange rule), the Company shall obtain shareholder approval in such a manner
and to such a degree as required.

          (b)  Without shareholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be

                                      -8-
<PAGE>

entitled to change the Offering Periods, limit the frequency and/or number of
changes in the amount withheld during an Offering Period, establish the exchange
ratio applicable to amounts withheld in a currency other than U.S. dollars,
permit payroll withholding in excess of the amount designated by a participant
in order to adjust for delays or mistakes in the Company's processing of
properly completed withholding elections, establish reasonable waiting and
adjustment periods and/or accounting and crediting procedures to ensure that
amounts applied toward the purchase of Common Stock for each participant
properly correspond with amounts withheld from the participant's Compensation,
and establish such other limitations or procedures as the Board (or its
committee) determines in its sole discretion advisable which are consistent with
the Plan.

          (c)  In the event the Board determines that the ongoing operation of
the Plan may result in unfavorable financial accounting consequences, the Board
may, in its discretion and, to the extent necessary or desirable, modify or
amend the Plan to reduce or eliminate such accounting consequence including, but
not limited to:

               (i)   altering the Purchase Price for any Offering Period
including an Offering Period underway at the time of the change in Purchase
Price;

               (ii)  shortening any Offering Period so that Offering Period ends
on a new Exercise Date, including an Offering Period underway at the time of the
Board action; and

               (iii) allocating shares.

          Such modifications or amendments shall not require stockholder
approval or the consent of any Plan participants.

     21.  Notices.  All notices or other communications by a participant to the
          -------
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

     22.  Conditions Upon Issuance of Shares.  Shares shall not be issued with
          ----------------------------------
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

          As a condition to the exercise of an option, the Company may require
the person exercising such option to represent and warrant at the time of any
such exercise that the shares are being purchased only for investment and
without any present intention to sell or distribute such shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned applicable provisions of law.

     23.  Term of Plan.  The Plan shall become effective upon the earlier to
          ------------
occur of its adoption by the Board of Directors or its approval by the
shareholders of the Company. It shall continue in effect for a term of ten (10)
years unless sooner terminated under Section 20 hereof.

                                      -9-
<PAGE>

     24.  Automatic Transfer to Low Price Offering Period.  To the extent
          -----------------------------------------------
permitted by any applicable laws, regulations, or stock exchange rules if the
Fair Market Value of the Common Stock on any Exercise Date in an Offering Period
is lower than the Fair Market Value of the Common Stock on the Enrollment Date
of such Offering Period, then all participants in such Offering Period shall be
automatically withdrawn from such Offering Period immediately after the exercise
of their option on such Exercise Date and automatically re-enrolled in the
immediately following Offering Period as of the first day thereof.

                            SUBSCRIPTION AGREEMENT


_____ Original Application                           Enrollment Date:___________
_____ Change in Payroll Deduction Rate
_____ Change of Beneficiary(ies)

1.   ____________________ hereby elects to participate in the Inventa
     Technologies, Inc. Employee Stock Purchase Plan (the "Employee Stock
     Purchase Plan") and subscribes to purchase shares of the Company's Common
     Stock in accordance with this Subscription Agreement and the Employee Stock
     Purchase Plan.

2.   I hereby authorize payroll deductions from each paycheck in the amount of
     ____% of my Compensation on each payday (from 0 to _____%) during the
     Offering Period in accordance with the Employee Stock Purchase Plan.
     (Please note that no fractional percentages are permitted.)

3.   I understand that said payroll deductions shall be accumulated for the
     purchase of shares of Common Stock at the applicable Purchase Price
     determined in accordance with the Employee Stock Purchase Plan.  I
     understand that if I do not withdraw from an Offering Period, any
     accumulated payroll deductions will be used to automatically exercise my
     option.

4.   I have received a copy of the complete Employee Stock Purchase Plan.  I
     understand that my participation in the Employee Stock Purchase Plan is in
     all respects subject to the terms of the Plan.  I understand that my
     ability to exercise the option under this Subscription Agreement is subject
     to shareholder approval of the Employee Stock Purchase Plan.

5.   Shares purchased for me under the Employee Stock Purchase Plan should be
     issued in the name(s) of (Employee or Employee and Spouse only).

6.   I understand that if I dispose of any shares received by me pursuant to the
     Plan within 2 years after the Enrollment Date (the first day of the
     Offering Period during which I purchased such shares) or one year after the
     Exercise Date, I will be treated for federal income tax purposes as having
     received ordinary income at the time of such disposition in an amount equal
     to the excess of the fair market value of the shares at the time such
     shares were purchased by me over the price which I paid for the shares.  I
                                                                              -
     hereby agree to notify the Company in writing within 30 days after the date
     ---------------------------------------------------------------------------
     of any disposition of my shares and I will make adequate provision for
     ----------------------------------------------------------------------
     Federal, state or other tax withholding obligations, if any, which arise
     ------------------------------------------------------------------------
     upon the
     --------
<PAGE>

     disposition of the Common Stock.  The Company may, but will not be
     -------------------------------
     obligated to, withhold from my compensation the amount necessary to meet
     any applicable withholding obligation including any withholding necessary
     to make available to the Company any tax deductions or benefits
     attributable to sale or early disposition of Common Stock by me.  If I
     dispose of such shares at any time after the expiration of the 2-year and
     1-year holding periods, I understand that I will be treated for federal
     income tax purposes as having received income only at the time of such
     disposition, and that such income will be taxed as ordinary income only to
     the extent of an amount equal to the lesser of (1) the excess of the fair
     market value of the shares at the time of such disposition over the
     purchase price which I paid for the shares, or (2) 15% of the fair market
     value of the shares on the first day of the Offering Period.  The remainder
     of the gain, if any, recognized on such disposition will be taxed as
     capital gain.

7.   I hereby agree to be bound by the terms of the Employee Stock Purchase
     Plan.  The effectiveness of this Subscription Agreement is dependent upon
     my eligibility to participate in the Employee Stock Purchase Plan.

8.   In the event of my death, I hereby designate the following as my
     beneficiary(ies) to receive all payments and shares due me under the
     Employee Stock Purchase Plan:

TO THE SERIES C PREFERRED
STOCK INVESTORS

      Re:   Inventa Corporation / Directed Share Program

Dear Investor:

      This letter shall confirm our understanding with respect to the purchase
by the Investors named on Schedule A attached hereto (the "Investors") of shares
of common stock in the event of the initial registered public offering (the
"IPO") by Inventa Corporation (the "Company") of its common stock. In connection
with the IPO, the Company shall use its best efforts to ensure that the managing
underwriters (the "UW") of the IPO establish a directed share program (the
"Program") in connection with the IPO. The number of shares (the "Shares") in
the Program shall consist of the greater of (i) that number of shares determined
by dividing $2,500,000 by the IPO offering price or (ii) 15% of the shares to be
offered in the offering (excluding shares related to the exercise of any UW
over-allotment option); provided, however, that the Shares shall not exceed that
number of shares determined by dividing $4,000,000 by the IPO offering price.
The Investors shall have the option, but not the obligation, to purchase or
direct the purchase of all or any portion of the Shares at the IPO price. The
Investors shall cooperate with the Company and the UW in all respects in order
to enable the Company to comply with its obligations hereunder. Each Investor
shall have the right to purchase, on a pro rata basis based on its ownership of
common stock issuable upon conversion of the Series C Preferred Stock, its share
of the Shares and any portion of the remainder of the Shares which other
Investors have elected not to purchase.

TO THE SERIES D PREFERRED
STOCK INSTITUTIONAL INVESTORS

      Re:   Inventa Corporation / Private Placement

Dear Investor:

      This letter shall confirm our understanding with respect to the purchase
by the Investors named on Schedule A attached hereto (the "Investors") of
unregistered shares of common stock of Inventa Corporation (the "Company") in a
private placement (the "Private Placement") that the parties intend to close in
the event of, and immediately prior to or contemporaneously with, the initial
firm commitment underwritten public offering (the "IPO") by the Company of its
common stock.

      1. Right to Participate in the Private Placement.

            (a) The Company shall use its commercially reasonable efforts to
close the Private Placement immediately before or contemporaneously with the
IPO. The terms of the Private Placement will provide, subject to the provisions
hereof, that the Company will offer each Investor the right to participate in
the Private Placement.

            (b) Subject to the terms hereof, the Company agrees to offer to the
Investors pursuant to the Private Placement a number of shares (the "Private
Placement Shares") equal to the greater of (a) the quotient obtained by dividing
$2,500,000 by the price at which shares are sold to the public in the IPO, less
underwriting discount (the "IPO Price") or (b) 15% of the shares to be offered
in the IPO (excluding shares related to the exercise of any Underwriters'
over-allotment option); provided, however, that the number of Private Placement
Shares shall not exceed that number of shares determined by dividing $3,000,000
by the IPO Price. The Investors that purchase shares of common stock in the
Private Placement shall become parties to an Investor Rights Agreement that
provides registration rights for the shares of common stock purchased in the
Private Placement similar to those granted to the Investors in connection with
their purchase of the Company's Series D Preferred Stock.

            (c) The Company shall offer to each Investor the right to purchase
its pro rata Share of the Private Placement Shares at the IPO Price. Each
Investor's "pro rata share" shall equal the quotient obtained by dividing (i)
the number of shares of Common Stock issuable or issued upon conversion of
shares of Series D Preferred Stock then held by such Investor, by (ii) the
number of shares of Common Stock issuable or issued upon conversion of shares of
Series D Preferred Stock
<PAGE>

then held by all Investors. All Private Placement Shares as to which Investors
do not indicate an interest in purchasing shall be reallocated on a pro rata
basis among the Investors who indicate an interest in purchasing more than their
pro rata share.

            (d) The Private Placement and all offers to be made to the Investors
shall be conducted in compliance with all applicable federal and state
securities laws and regulations, including, without limitation, the Securities
Act of 1933, as amended (the "Securities Act"), and all applicable rules and
regulations promulgated by the National Association of Securities Dealers, Inc.
and other such self-regulating or quasi-public regulatory organizations. The
Investors participating in the Private Placement shall comply with all
reasonable requirements and procedures required by the Company of all Investors
participating in the Private Placement (provided such requirements and
procedures do not materially and adversely affect the participation rights
granted in this Section 1), if any.

      2. Alternative Transaction. Notwithstanding the foregoing, in the event
that (a) regulatory authorities continue to object to this arrangement after
full discussion and negotiation with the Company and its legal counsel (with the
participation of one legal counsel representing Investors, if desired by
Investors); (b) regulatory authorities allow the Company to fulfill its
obligations under this arrangement only on the condition that recission rights
or other specific liability will be assumed by the Company or the underwriters
or that special risks related to the Private Placement be included in the
prospectus filed in connection with the IPO; (c) the resolution with regulatory
authorities relating to this arrangement would delay the Company's offering
beyond delays caused by comments from regulatory authorities with respect to
other issues, provided that the Company has used its good faith efforts (with
the participation of one legal counsel representing Investors, if desired by
Investors) to timely resolve any regulatory issues that arise in connection with
this arrangement; or (d) regulatory authorities do not allow the Company to
issue securities of the Company to the holders of the Company's Series C
Preferred Stock (the "Series C Holders") at the time of the IPO, then the
Company and the Investors agree to negotiate in good faith to enter into an
alternative transaction that as closely as practicable approximates the economic
benefit of the Private Placement. Additionally, if the Company and the Series C
Holders agree to reduce the number of shares available to the Series C Holders
at the time of the IPO from the number set forth in that certain Letter
Agreement dated May 11, 1998, the number of shares available in the Private
Placement shall be reduced accordingly, but in no event shall the number of
shares available in the Private Placement be reduced to less than the number
determined by dividing $2,000,000 by the IPO Price, unless required as a result
of any of the reasons set forth in clauses (a) through (d) of this section 2.

                               INVENTA CORPORATION

                           PRIVATE PLACEMENT AGREEMENT

      This Agreement is made as of January 28, 2000, among Inventa Corporation
(the "Company") and the entities listed on Schedule A hereto (individually, a
"Purchaser" and, collectively, the "Purchasers").

      Reference is made to the letter agreement (the "Letter Agreement") dated
as of January 14, 2000, among the Company and the Purchasers. Capitalized terms
used herein but not defined herein shall have the meanings given to them in the
Letter Agreement.

      1. Sale of Shares. The Company shall issue and sell to each Purchaser
listed on Schedule A, and each Purchaser shall purchase, the number of shares of
the Company's unregistered common stock (the "Shares") having the aggregate
purchase price set forth opposite such Purchaser's name on Schedule A, which
number represents such Purchaser's "pro rata share" of the Private Placement as
defined in the Letter Agreement, or such other number as agreed to by the
Company and the Purchaser. The price per share shall be equal to the price (the
"IPO Price") at which the Company offers its common stock to the public in its
initial firm commitment underwritten public offering (the "IPO"), less the
underwriting discount.

      2. Registration Rights. Each Purchaser that has purchased Shares pursuant
to the terms of this Agreement shall become a party to the Investor Rights
Agreement between the Company and the holders of the Company's preferred stock
and shall be a "Holder" thereunder with respect to such Shares, all of which
shall be deemed "Registrable Securities" for all purposes thereunder. All
consents required to be obtained in connection with the granting of these rights
have been or will be obtained by the Company prior to the closing of the IPO.

      3. Binding Agreement. This agreement represents a binding commitment by
the Company and the Purchasers. The closing of the sale, and the issuance of the
Shares hereunder, are subject to no conditions other than (a) the closing of the
IPO; (b) each Purchaser's payment for the shares shall occur contemporaneously
with the closing of the IPO; (c) no objection by regulatory authorities to this
Private Placement after full discussion and negotiation with the Company and its
legal counsel (with the participation of one legal counsel representing
Investors, if desired by Investors); (d) that no law, regulation, or regulatory
order requires that recission rights or other specific liability be assumed by
the Company or the underwriters or that special risks related to the Private
Placement be included in the prospectus filed in connection with the IPO; or (e)
that no delay in the IPO process be caused by resolution of matters related to
this Private Placement beyond delays caused by comments from regulatory
authorities with respect to other issues, provided that the Company has used its
good faith efforts (with the participation of one legal counsel representing
Investors, if desired by Investors) to timely resolve any regulatory issues that
arise in connection with this arrangement
<PAGE>

      4. Counterparts. This agreement may be executed in counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.
<PAGE>

      IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed by their duly authorized officers as of the date and year first above
written.

Company received by the Shareholder in the Acquisition and all shares
subsequently received in respect thereof as a consequence of stock dividends,
stock splits, reverse stock splits, recapitalizations, mergers, reorganizations
or the like, and all new, substituted or additional securities or other

ownership of the Shares.

          (b) "Unvested Shares" shall mean any of the Shares which have not yet
               ---------------
been released pursuant to Section 2 below from the Company's Repurchase Option
described in Section 3.

          (c) "Repurchase Option" shall have the meaning set forth in Section 3.
               -----------------

     2.   Vesting. The Shares shall vest and be released from the Company's
Repurchase Option in accordance with the following provisions:

          (a) Thirty-five percent (35%) of the total number of Shares shall vest
and be released immediately upon the closing of the Acquisition;

          (b) Sixty-five percent (65%) of the Shares shall be subject to the
Company's Repurchase Option as of January ___, 2000 (the "Release Start Date").

<PAGE>

          (i)  Fifteen percent (15%) of the Shares shall vest and be released

and be released from the Repurchase Option beginning on the last day of the
month in which the first anniversary of the Effective Date of this Agreement

                                                                              -
months based upon Shareholder's continued employment with Company until all such
Shares are released, after a total elapsed period of three (3) years from the
Effective Date of this Agreement.

  3. Repurchase Option; Termination.
     ------------------------------

     (a) Repurchase.  Effective as of the date (the "Termination Date") which is
         ----------
the date of (i) receipt by the President or Controller of the Company of written
notice of Shareholder's voluntary termination of employment, or (ii) the
involuntary termination for cause of the Shareholder's employment with or
service to the Company, the Company or its assignee shall have an irrevocable,
exclusive option (the "Repurchase Option") for a period of fifteen (15) business
days from the Termination Date to repurchase at a price equal to $.01 per share
(the "Purchase Price") up to that number of shares which shall constitute
Unvested Shares as of the Termination Date. For the purposes of this Agreement
"cause" means, and is limited to, the following: the Shareholder's (1) gross
negligence in the performance of his agreed upon duties for the Company; (2)
willful refusal to follow directives of Company senior management after receipt
of written warning with respect thereto, which is not cured within five (5)
business days thereof; (3) commission of a felony; (4) inability to perform his
agreed upon duties for the Company by reason of alcoholism or drug dependency;
and (5) refusal to appear at his regular place of work for the Company. A
resignation by the Shareholder from his employment with or service to the
Company shall be for "Good Reason" if: (a) the regular place of Shareholder's
employment is relocated to a site more than thirty (30) miles from the
Shareholder's established regular site of employment at the time of Closing, or
(b) there is a reduction in the Shareholder's annual compensation from the
Company, unless at least seventy five percent (75%) of all other employees in
the same class are also subject to the same percentage reduction in their annual
compensation from the Company. Nothing in this Section 3(a) shall preclude the
Shareholder's right to claim that his termination was the result of a
constructive termination, and if Shareholder prevails on said constructive
termination claim, the termination shall then be deemed to have been with "Good
Reason".

     (b) Termination.  Anything to the contrary not withstanding, if the
         -----------
Shareholder's employment with or service to the Company shall be terminated (i)
by the Company without cause, or (ii) by the Shareholder for Good Reason, or
(iii) upon the Shareholder's death or permanent disability, then in any such
event, effective as of the date of such event (the "Expiration Date"), the
Repurchase Option with respect to such Unvested Shares shall automatically and
immediately be terminated and released, and such Unvested Shares shall vest in
accordance with Section 2(b)(i) and (ii) but without regard to the continued
employment requirement.

     (c) Mechanics of Repurchase.  In order to exercise the Repurchase Option,
         -----------------------
the Company shall deliver written notice of exercise to Shareholder within the
time period specified in

                                      -2-
<PAGE>

paragraph (a). The Company shall pay to Shareholder within the time period
specified in paragraph (a), the aggregate repurchase price by cash or check.
Upon delivery of such notice, (i) the Company or its assignee shall become the
legal and beneficial owner of the Shares being repurchased and all rights and
interests therein or relating thereto, (ii) the Company shall have the right to
retain and transfer to its own name or the name of its assignee the repurchased
Shares, and (iii) Shareholder shall retain solely the right to receive the
payment for the Shares so repurchased.

  4.   Restrictions on Transfer.  Except for the transfer of Unvested Shares to
       ------------------------
the Company or its assignee as contemplated by this Agreement, no Unvested
Shares or any beneficial interest therein shall be transferred, encumbered or
otherwise disposed of in any way until the release of such Shares from the
Repurchase Option in accordance with the provisions of this Agreement.

  5.   Legends.  The share certificate evidencing the Shares shall be endorsed
       -------
with the following restrictive legends (in addition to any legend required under
applicable state securities laws):

  THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT
  AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR DISTRIBUTION
  THEREOF, AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933. SUCH
  SHARES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR
  UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL REASONABLY ACCEPTABLE TO IT
  SAYING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND
  PROSPECTUS DELIVERY REQUIREMENTS OF SAID ACT.

  THE SHARES REPRESENTED HEREBY ARE SUBJECT TO CERTAIN RESTRICTIONS UPON
  TRANSFER AND RIGHTS OF REPURCHASE AS SET FORTH IN AN AGREEMENT BETWEEN THE
  COMPANY AND THE SHAREHOLDER, A COPY OF WHICH IS AVAILABLE UPON THE REQUEST OF
  THE REGISTERED HOLDER HEREOF TO THE SECRETARY OF THE COMPANY.

  6.   Adjustments for Stock Splits, etc.  All references to the number of
       ---------------------------------
Shares and the purchase price of the Shares in this Agreement shall be
appropriately adjusted to reflect any stock dividend, stock split,
recapitalization, merger, reorganization or other change in the Shares which may
be made by the Company after the date of this Agreement.

  7.   Escrow.  As security for the faithful performance of this Agreement,
       ------
Shareholder agrees, immediately, to deliver such certificate(s), together with
two stock powers in the form attached hereto as Exhibit B, executed by
Shareholder (with the date and number of Shares left blank), to the Secretary of
the Company ("Escrow Agent").  Escrow Agent shall hold such Shares pursuant to
an escrow agreement in the form attached hereto as Exhibit A, by which Escrow
Agent shall be authorized to take all such actions and to effectuate all such
transfers and/or releases of such

                                      -3-
<PAGE>

Shares as are in accordance with the terms of this Agreement. The Shares shall
be released from escrow upon termination of the Repurchase Option provided for
in Section 3.

  8.   Market Stand-Off Agreement.  Shareholder and each transferee of the
       --------------------------
Shares issued hereunder agrees by acceptance hereof or thereof not to sell, make
a short sale of, loan, grant any options for the purchase of, or otherwise
dispose of any shares of Common Stock of the Company held by Shareholder without
the prior written consent of the Company or the underwriters managing any
underwritten public offering of the Company's securities, for such period from
the effective date of the offering as the managing underwriters shall request
(but not to exceed one hundred eighty (180) days), and further agrees to execute
any agreement reflecting the above provision as may be requested by the
underwriters at the time of any such public offering.

agreements hereunder shall inure to the benefit of, and be enforceable by the

Agreement shall not in any way be construed as a waiver of any such provision or
provisions, nor prevent that party from thereafter enforcing each and every

Secretary

Inventa Corporation
255 Shoreline Drive, Suite 200
Redwood Shores, CA 94065

Dear Sir:

     As Escrow Agent for both Inventa Corporation, a California corporation (the
"Company"), and the undersigned holder of stock of the Company ("Shareholder"),
you are hereby authorized and directed to hold the documents delivered to you
pursuant to the terms of that certain Stock Restriction Agreement ("Agreement")
between the Company and the undersigned, to which a copy of these Joint Escrow
Instructions is attached as Exhibit A, in accordance with the following
                            ---------
instructions:

     1.   In the event the Company and/or any assignee of the Company (referred
to collectively for convenience herein as the "Company") exercises the
Repurchase Option set forth in the Agreement, the Company shall give to
Shareholder 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. Shareholder and the Company hereby irrevocably
authorize and direct you to close the transaction contemplated by such notice in
accordance with the terms of the notice, unless you receive objection from such
Shareholder within ten days of such notice, in which event you shall hold the
Shares subject to the notice, and all dividends related thereto, until the
dispute with respect to such Shares is resolved by the parties, or by
arbitration or a court of competent jurisdiction. Until resolved neither the
Company nor the Shareholder shall have the right to vote such Shares.

     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 the same, together with the certificate
evidencing the shares of stock to be transferred, to the Company or its
assignee, in accordance with the Agreement, against the simultaneous delivery to
you of the purchase price (by check) for the number of shares of stock being
purchased pursuant to the exercise of the Repurchase Option.

     3.   Shareholder irrevocably authorizes the Company to deposit with you any
certificates evidencing shares of stock to be held by you hereunder and any
additions and substitutions to the shares as defined in the Agreement.
Shareholder does hereby irrevocably constitute and appoint you as his attorney-
in-fact and agent for the term of this escrow to execute with respect to such
securities all documents necessary or appropriate to make such securities
negotiable and to complete any

                                       1

transaction herein contemplated. Subject to the provisions of this paragraph 3,
Shareholder shall exercise all rights and privileges of a stockholder of the
Company while the stock is held by you.

     4.   Upon written request of Shareholder, but no more than once each year,
unless the Repurchase Option has been exercised, you will deliver to Shareholder
a certificate or certificates representing so many shares of stock as have been
released from the Unvested Shares subject to the Repurchase Option in accordance
with the terms thereof. Fifteen days (15) after the Expiration Date, you will
deliver to Purchaser a certificate or certificates representing the aggregate
number of Shares not purchased by the Company or its assignees pursuant to

     5.   Your duties hereunder may be altered, amended, modified or revoked
only by a writing signed by all of the parties hereto.

genuine and to have been signed or presented by the proper party or parties.
You shall not be personally liable for any act you may do or omit to do
hereunder as Escrow Agent or as attorney-in-fact for Shareholder 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.

     7.   You are hereby expressly authorized to comply with and obey orders,
judgments or decrees of any duly approved arbitrator or court of competent
jurisdiction. In case you obey or comply with any such order, judgment or
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.

     8.   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.

     9.   You shall not be liable for the outlawing of any rights under any
applicable statute of limitations with respect to these Joint Escrow
Instructions or any documents deposited with you.

     10.  You shall be entitled to employ such legal counsel and other 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.

     11.  Your responsibilities as Escrow Agent hereunder shall terminate if you
shall cease to be an officer of the Company or if you shall resign by written
notice to each party. In the event of any such termination, the Company and the
Shareholder shall appoint a successor Escrow Agent satisfactory to both of them.

     12.  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.

     13.  It is understood and agreed that should any dispute arise with respect
to the delivery and/or ownership or right of possession of the securities held
by you hereunder, by written objection or other written notice of any party
hereto, or otherwise, you are authorized and directed to retain in your
possession without liability to anyone all or any part of said securities until
such disputes shall have been settled either by mutual written agreement of the
parties concerned or by a final order, decree or judgment of a duly appointed
arbitrator or court of competent jurisdiction after the time for appeal has
expired and no appeal has been perfected, but you shall be under no duty
whatsoever to institute or defend any such proceedings.

     14.  Any and all disputes or controversies arising from or respecting this
agreement shall be decided by binding arbitration under the rules of the
American Arbitration Association. The arbitrator shall consist of one arbitrator
mutually agreed upon by both parties. Arbitration shall take place in San Mateo
County, California or any other location mutually agreeable to the parties. At
the request of either party, arbitration proceedings will be conducted in the
utmost secrecy. The arbitrator shall be able to decree any and all relief of an
equitable nature and to award damages, with or without an accounting and costs.
The decree of judgment of an award rendered by the arbitrator may be entered in
any court of competent jurisdiction.

delivery: three (3) business days after the business day of deposit in the
United States Post Office, by registered or certified mail with postage and fees
prepaid; one (1) business day after the business day of facsimile transmission,

overnight carrier, freight prepaid; in any such case addressed to each of the
other parties thereunto entitled at the addresses indicated in the Company's
records, or at such other addresses as a party may designate by ten days'
advance written notice to each of the other parties hereto.

     16.  By signing these Joint Escrow Instructions, you become a party hereto
only for the purpose of said Joint Escrow Instructions; you do not become a
party to the Agreement.

                           NONCOMPETITION AGREEMENT
                           ------------------------

     This NONCOMPETITION AGREEMENT (the "Agreement"), dated the [_____] day of
[____________, 2000] (the "Effective Date") is made by and between Inventa
Corporation, a California corporation ("Inventa"), XTend-Tech, Inc., a Delaware
Corporation ("XTend") and ____________ (the "Employee").

                                  BACKGROUND
                                  ----------

     This Agreement is entered into in connection with and is a condition to the
Agreement dated as of January __, 2000 (the "Agreement") between Inventa
Corporation and XTend, pursuant to which Inventa has acquired all outstanding
shares of XTend including all shares held by Employee on the date hereof ("the
Acquisition").

     Employee is a stockholder and key employee of XTend and has been actively
involved in the development and/or marketing of XTend's products. Inventa
intends to continue the business of XTend after the Effective Date and integrate
such business into its ongoing business. To preserve and protect the assets of
XTend, including XTend's goodwill, customers and trade secrets of which Employee
has, and will, in his role as an employee of XTend or Inventa, have knowledge,
and to preserve and protect XTend's and Inventa's goodwill and business
interests going forward, and in consideration for Inventa's undertaking the
Acquisition, Employee has agreed to enter into this Agreement.

     Employee and Inventa believe the limitations as to time, geographical area
and scope of activity contained in this Agreement are reasonably necessary to,
and no greater than that required to, protect the goodwill and business
interests purchased by Inventa.

     1.  Noncompete.  During the Restricted Period, Employee shall not either
         ----------
for himself or on behalf of any other person, partnership, firm, association or
corporation in any territory in which Inventa is actively engaged in business
(a) undertake any business which is in competition with any business of XTend or
Inventa as operated by Inventa as of the date of termination, (b) act as an
employee, agent, advisor or consultant of any then existing competitor of XTend
or Inventa with respect to any business which had been operated by XTend
immediately prior to the date of termination, (c) accept employment or perform
services for any of Inventa's competitors with respect to any business operated
by XTend immediately prior to the date of termination, (d) take any action to or
do anything reasonably intended to divert business from Inventa or influence or
attempt to influence any existing customers of Inventa to cease doing business
with Inventa or to alter its then existing business relationship with Inventa,
in each case with respect to any business operated by XTend immediately prior to
the date of termination, (e) hire, or solicit for purposes of hiring any
employees of XTend or Inventa, or (f) take any action or do anything reasonably
intended to influence any existing suppliers of Inventa to cease doing business
with Inventa or to alter its then existing business relationship with Inventa,
in each case with respect to any business operated by XTend immediately prior to
the date of termination. As used herein, "Restricted Period" means (i) two (2)
years following the termination by the Company of Employee's employment or
service
<PAGE>

with Inventa for cause, (ii) one (1) year following the termination of
Employee's employment or service with Inventa by Inventa without cause, or by
Employee for "good reason", or (iii) the period ending two (2) years from the
date Employee voluntarily terminates his employment or service with Inventa
without good reason, whichever of (i) through (iii) is applicable.

     2.  Geographic Area.  The geographical areas in which the restrictions
         ---------------
provided for in this Agreement apply include all cities, counties and states of
the United States, and all other countries, in which XTend or Inventa or any of
its subsidiaries has engaged in licensing or sales or otherwise conducted
business or selling or licensing efforts at any time during the two years prior
to the Effective Date or during the term of this Agreement. The agreement not to
compete in each such geographic subdivision is a separate and severable
agreement from all such other agreements. Employee acknowledges that the scope
and period of restrictions and the geographical area to which the restrictions
imposed in this Section applies are fair and reasonable and are reasonably
required for the protection of Inventa and that this Agreement accurately
describes the business to which the restrictions are intended to apply.

     3.  Severability.  The parties intend that the covenants contained in this
         ------------
Agreement shall be construed as a series of separate covenants, one for each
county of each state of the United States of America, and each nation. Except
for geographic coverage, each such separate covenant shall be deemed identical
in terms of the covenants contained in this Agreement. If, in any judicial
proceeding, a court shall refuse to enforce any of the separate covenants (or
any part thereof) deemed included in this Agreement, then such unenforceable
covenant (or such part) shall be deemed eliminated from this Agreement for the
purpose of those proceedings to the extent necessary to permit the remaining
separate covenants (or portions thereof) to be enforced. In the event that the
provisions of this Agreement should ever be deemed to exceed the time or
geographic limitations, or the scope of these covenants, as permitted by
applicable law, then such provisions shall be reformed to the maximum time or
geographic limitations, as the case may be, permitted by applicable laws.

     4.  Injunctions.  Employee acknowledges that any breach of the covenants of
         -----------
this Agreement may result in immediate and irreparable injury to Inventa and,
accordingly, consents to the application of such injunctive relief and such
other equitable remedies for the benefit of Inventa as a court of competent
jurisdiction may deem appropriate in the event such a breach occurs or is
threatened. The foregoing remedies will be in addition to all other legal
remedies to which Inventa may be entitled hereunder, including, without
limitation, monetary damages.

     5.  Miscellaneous.
         -------------

         (a) Notices.  Any and all notices permitted or required to be given
under this Agreement must be in writing. Notices will be deemed given (i) when

by commercial overnight courier with written verification of receipt, or (iii)

prepaid, whichever occurs first, at the address set forth below or at any new
