                               PROSPECTUS SUMMARY

   You should read the following summary together with the more detailed
information regarding our company and the common stock being sold in this
offering and our historical financial statements and notes to those statements
included elsewhere in this prospectus. You should carefully read the entire
prospectus, including "Risk Factors" and the financial statements, before
making an investment decision.

                                  Our Business

   We provide comprehensive Internet-based solutions to create many-to-many
communication, commerce and collaboration eHubs for businesses. An eHub is an
Internet-based workspace where customers, partners, suppliers and employees can
simultaneously interact, access real-time business information, integrate
business processes and conduct eCommerce transactions. We believe our solutions
represent a new paradigm for eBusiness, and are designed to deliver secure,
real-time content and eCommerce capabilities from virtually any source to any
user, at any time.

   Our solutions represent a new category of business-to-business platforms
designed to deliver dial-tone-like reliability and functionality, which we
refer to as Web-tone. We believe our Web-tone business model is better aligned
with our customers' needs because it is based on recurring fees for solutions,
services and transaction capabilities, instead of a large one-time capital
investment usually associated with software license purchases. Our business
model provides our customers the flexibility to adjust the type of services
they receive from us in response to their changing business needs, and provides
us with the incentive to innovate and serve them since we share in their long-
term success.

   The impact of the Internet on traditional commerce models extends far beyond
the dollar value of commerce activity conducted over the Internet and has led
to the emergence of entirely new business models. To remain competitive,
companies are beginning to leverage the Internet as a primary business platform
to collaborate, interact, and conduct business. Gartner Group estimates that
business-to-business eCommerce using the Internet will grow from $145 billion
in 1999 to $7.3 trillion in 2004. Moreover, Forrester Research also estimates
that business-to-business eCommerce will account for more than 93% of U.S.
eCommerce transactions by 2004.

   Our objective is to become the leading provider of comprehensive Internet-
based solutions to create many-to-many communication, commerce and
collaboration eHubs for businesses. Key elements of this strategy include
leveraging our Web-tone business model, establishing 2Bridge as a leading
global brand enabling eHub solutions, broadening adoption of 2Share throughout
our existing customer base, targeting strategic markets, and building strategic
alliances to strengthen our market position and offering.

   2Share is designed to empower our customers, who are highly dependent on
real-time information exchange, to rapidly and seamlessly develop customized
eHubs. We believe our solutions create value by enabling firms to strengthen
business and employee relationships, improve time to market, increase revenue
and new market opportunities, and improve return on investment of existing
corporate assets. Since the introduction of 2Share in 1998, we have delivered
our solutions to customers in a number of strategic industries, including J.P.
Morgan & Co. Incorporated, The McGraw-Hill Companies, SAP AG, Schroders &
Company, and Visa USA.

  . assumes that the underwriters do not exercise their over-allotment option

after deducting the underwriting discounts and commissions and estimated
offering expenses.

                                  RISK FACTORS

   You should carefully consider the following risk factors and the other
information in this prospectus, including our consolidated financial statements
and the related notes, before investing in our common stock. Our business,
operating results or financial condition could be seriously harmed by any of
the following risks. The trading price of our common stock could decline due to
any of these risks, and you may lose all or part of your investment.

                         Risks Related To Our Business

We are an early stage company, so we have only a limited operating history with
which you can evaluate our business and prospects.

   We commenced our current operations in January 1997 and began selling our
2Share solution in the fourth quarter of 1998. Accordingly, we have only a
limited operating history with which you can evaluate our business and our
prospects. In addition, our prospects must be considered in light of the risks
encountered by companies in the early stages of development in new and rapidly
evolving markets, especially the business-to-business eCommerce markets. Some
of the risks we face include our ability to:

  . attract and retain customers;

  . hire aggressively to expand our services, sales and marketing efforts;

  . predict the acceptance and adoption of our recurring fee-based business
    model;

  . expand our 2Share solution and develop new solutions and services;

  . negotiate and maintain favorable strategic relationships; and

  . plan and manage our growth effectively.

   If we fail to manage these risks successfully, our business could be harmed.

We expect to incur losses in the future.

   Our current operations have never been profitable. We have incurred net
losses in every fiscal period since we began our current operations. For the
year ended December 31, 1999, our net loss was $17.3 million. As of December
31, 1999 our accumulated deficit was $27.9 million. We expect to substantially
increase our sales personnel, marketing expenses, and services and operations
expenses. As a result, we will need to generate significant additional revenues
to achieve and maintain profitability in the future. We are not certain when we
will become profitable, if ever. Even if we do achieve profitability, we may
not sustain or increase profitability on a quarterly or annual basis. Failure
to achieve or maintain profitability will materially and adversely affect the
market price of our common stock.

We have not been able to fund our operations from cash generated by our
business, and we may not be able to do so in the future.

   We have principally financed our operations to date through the private
placement of shares of our preferred stock and bank borrowings. If we do not
generate sufficient cash resources from our business to fund operations, our
growth could be limited unless we are able to obtain additional capital through
equity or debt financings. Our inability to grow as planned may reduce our
chances of achieving profitability, which, in turn, could have a material
adverse effect on the market price of our common stock.

                                       6

Our quarterly financial results fluctuate and are difficult to predict and, if
our future results are below the expectations of the public market analysts and
investors, the price of our common stock may decline.

   Our quarterly revenues and results of operations are difficult to predict.
We have experienced, and expect to continue to experience, fluctuations in
revenues and operating results from quarter to quarter. As a result, we believe
that quarter-to-quarter comparisons of our revenues and operating results are
not necessarily meaningful, and that such comparisons may not be accurate
indicators of future performance. The reasons for these fluctuations include,
but are not limited to:

  . the amount and timing of operating costs relating to the expansion of our
    business, operations and infrastructure;

  . the number and timing of new hires, particularly with respect to services
    and operations personnel;

  . the timing of our sales cycles;

  . our ability to meet scheduled eHub implementations; and

  . our utilization rate for our services and operations personnel.

   We plan to significantly increase our technology, services and operating
expenses to expand our sales personnel, establish our brand and meet customer
needs. Our operating expenses, which include sales and marketing, research and
development and general and administrative expenses, are based on our
expectations of future revenues and are relatively fixed in the short term. If
revenues fall below our expectations during a quarter and we are not able to
quickly reduce our spending in response, our operating results for that quarter
could be harmed. It is likely that in some future quarter our operating results
may be below the expectations of public market analysts and investors and, as a
result, the price of our common stock may fall.

If our recurring fee-based business model is not accepted by our customers, our
revenues and business will be adversely affected.

   We plan to receive substantially all of our future revenues from the sale of
our 2Share solution on a recurring fee basis from our customers. This model is
different from that of most enterprise software providers who generally offer
perpetual licenses and receive a single payment at the time of the license
grant. We began selling our products and services on a recurring fee basis in
the fourth quarter of 1999 and therefore do not have a lengthy operating
history to determine the acceptance of our model. If our recurring fee-based
business model were to ultimately prove unattractive to potential customers who
are accustomed to licensing software on a single payment basis, we would likely
have to adopt an alternate business model and accordingly we might lose
recurring revenue streams on which our business model is based. In addition,
our recurring fee-based contracts with our customers generally come up for
renewal annually and are terminable upon prior notice. If a significant portion
of our customers were to elect not to renew their contracts in the future, our
revenues may decline which would harm our business, operating results and
financial condition.

We expect to depend on 2Share for a significant portion of our revenues for the
foreseeable future and if it does not achieve broad market acceptance, our
revenues could decline.

   We currently derive all of our revenues from selling our 2Share solution and
providing related services and support. We expect that we will continue to
derive a substantial amount of our revenues from sales of 2Share for the
foreseeable future. Consequently, a decline in the price of, or demand for,
2Share, or its failure to achieve broad market acceptance, could seriously harm
our business and results of operations.

                                       7
<PAGE>

Our customer base is concentrated and loss of a major customer could cause our
revenues to decline.

   During the year ended December 31, 1999, four customers accounted for
approximately 83% of our total revenues. We may continue to derive a
significant portion of our revenues from a relatively small number of customers
in the future. If a major customer decided not to renew its contract with us,
our revenues could decline and our operating results and financial condition
could be harmed.

Variations in our sales cycle could impact the timing of our revenues, causing
our quarterly operating results to fluctuate.

   The period between our initial contact with a potential customer and the
purchase of our solution ranges from approximately 30 to 180 days and may vary
depending on the nature of the services requested by the customer and the size
of the customer. A lengthy sales cycle may have an impact on the timing of our
revenues, which in turn could cause our quarterly operating results to
fluctuate. A customer's decision to purchase our solution is discretionary, and
is influenced by many factors beyond our control, such as customer budgetary
cycles. To successfully sell our 2Share solution, we generally must educate our
potential customers regarding its use and benefits, which can require
significant time and resources.

We may not be able to increase market awareness and sales of our 2Share
solution if we do not expand our sales and distribution capabilities.

   We need to substantially expand our sales and distribution efforts in order
to increase market awareness and sales of our 2Share solution and the related
services we offer. We have recently expanded our direct sales force and plan to
hire additional sales personnel. We must have a sales force with an industry-
and technology-focused background which can be targeted at multiple departments
within an organization. Competition for qualified sales and marketing personnel
is intense, and we might not be able to hire and retain adequate numbers of
these personnel to maintain our growth. New hires will require training and
take time to achieve full productivity. Our competitors have attempted to hire
our employees away from us and we expect that they will continue such attempts
in the future. We also plan to expand our relationships with existing customers
both inside the customer organization and with their customers, partners and
suppliers and to grow these relationships into additional sales opportunities
for our solution. If we are unable to successfully grow our sales capabilities,
we may be unable to expand our relationships in this way, or at all, and our
revenues may decline.

Our operating results may decline and our customers may become dissatisfied if
we do not expand our services and operations organization or if we are unable
to provide continuing service.

   We cannot be certain that we can attract or retain a sufficient number of
highly qualified services and operations personnel. Customers that purchase our
solution typically engage our services and operations staff to assist with
support, design, consulting and implementation. We believe that growth in our
sales depends on our ability to provide our customers with these services,
either directly or through partners. As a result, we plan to increase the
number of our services and operations personnel to meet these needs. New
services and operations personnel will require training and education and take
time to reach full productivity. To meet our customers' implementation needs,
we may be required to use costly third-party consultants to supplement our
internal resource capabilities. Competition for qualified personnel is intense,
particularly because we are in a new market and only a limited number of
individuals have developed the skills required to provide the services our
customers require. Our business may be harmed if we are unable to hire and
retain new services and operations personnel.

                                       8

Delays in implementation of our solution could cause our operating results to
suffer.

   The implementation of our solution requires internal quality assurance
testing and customer testing which may reveal performance issues that could
lead to delays in setting up our solution for customers. In addition, the
reallocation of resources associated with any postponement could cause delays
in the implementation of our solution at other customer sites and may adversely
affect or delay our ability to develop and release future enhancements to our
existing solution as well as new solutions. Any such delays could harm our
operating results.

Our industry is highly competitive and we may not be able to compete
effectively.

   The market for business-to-business communication, commerce and
collaboration solutions is changing rapidly and intensely competitive. We
expect competition to intensify as the number of entrants and new technologies
increases. We may not be able to compete successfully against current or future
competitors. The competitive pressures facing us may harm our business,
operating results and financial condition.

   Our current and potential competitors include, among others, both private
and public companies which are perceived as providing solutions similar to
ours, or which actually provide components of the solutions we provide, such as
companies which construct ePortals. In addition, our customers and companies
with whom we currently have strategic relationships may become competitors in
the future. Many of our competitors and potential competitors possess larger
technical staffs, larger customer bases, more established distribution
channels, greater brand recognition and greater financial, marketing and other
resources than we do. Our competitors may be able to develop products and
services that are superior to our solution, have significantly improved
functionality as compared to our existing and future solutions and achieve
greater customer acceptance. In addition, negotiating and maintaining favorable
customer and strategic relationships is critical to our business. Our
competitors may be able to negotiate strategic relationships on more favorable
terms than we are able to negotiate. Many of our competitors may also have
well-established relationships with our existing and prospective customers.
Increased competition may result in reduced margins, loss of sales or decreased
market share that in turn could harm our business, operating results and
financial condition.

We have experienced significant growth in our business in recent periods and we
may not be able to manage our future growth successfully.

   Our ability to successfully deploy our solution and implement our business
plan in a rapidly evolving market requires an effective planning and management
process. We have increased, and plan to continue to increase, the scope of our
operations at a rapid rate. The number of people we employ has grown and we
expect it to continue to grow substantially. We expanded from 43 employees as
of December 31, 1998 to 124 employees as of March 10, 2000. Future expansion
efforts could be expensive and may strain our managerial and other resources.
To manage future growth effectively, we must maintain and enhance our financial
and accounting systems and controls, integrate new personnel and manage
expanded operations. If we do not manage growth properly, it could harm our
business, operating results and financial condition.

If the software components of our solution are unreliable, we could lose
customers and revenues.

   Software included in solutions such as ours may contain known and undetected
errors or performance problems. Many serious defects are frequently found
during the period immediately following introduction of new software or to
enhancements to existing software. Although we attempt to resolve all errors we
believe our customers would consider serious, our technology is not

                                       9
<PAGE>

error-free. Undetected errors or performance problems may be discovered in the
future and our customers may consider known errors to be more serious than we
do. This could result in lost revenues or delays in customer acceptance and
could be detrimental to our reputation, which could harm our business,
operating results and financial condition.

We rely on third-party technologies and a termination of any of our
relationships with third-party vendors could adversely affect our revenues and
business.

   We use third-party technologies in our 2Share solution. If our third-party
technology vendors terminate their agreements to license their technologies to
us and we are not able to find replacement technologies, our ability to deploy
our 2Share solution may suffer, our revenues could decline and our operating
results and financial condition could be harmed.

Our executive officers and certain key personnel are critical to our business
and these officers and key personnel may not remain with us in the future.

   Our future success depends upon the continued service of our executive
officers and other key personnel. We do not require any of our officers or key
employees to work for us for any specific amount of time nor are they under any
employment agreements. If we lose the services of one or more of our executive
officers or key employees, or if one or more of them decide to join a
competitor or otherwise compete directly or indirectly with us, our business,
operating results and financial condition could be harmed. In particular,
Mansoor Zakaria, our Chairman of the Board and Chief Executive Officer, would
be particularly difficult to replace.

If we cannot meet our future capital requirements, we may not be able to
develop or enhance our solution, take advantage of business opportunities and
respond to competitive pressures.

   We currently anticipate that the net proceeds from this offering, together
with our existing working capital immediately prior to this offering, will be
sufficient to meet our anticipated working capital and capital expenditure
requirements for at least the next 12 months. The time period for which we
believe our capital is sufficient is an estimate. The actual time period may
differ materially as a result of a number of factors, risks and uncertainties.
We may need to raise additional funds in the future through public or private
debt or equity financings in order to:

  . take advantage of opportunities, including more rapid international
    expansion or acquisitions of complementary businesses or technologies;

  . develop new solutions;

  . build our brand; or

  . respond to competitive pressures.

   Any additional financing we may need in the future may not be available on
terms favorable to us, if at all. If adequate funds are not available or are
not available on acceptable terms, we may not be able to take advantage of
opportunities, develop new solutions or otherwise respond to unanticipated
competitive pressures. In such case, our business, operating results and
financial condition could be harmed.

We intend to expand our international sales efforts but do not have substantial
experience in international markets.

   We intend to expand our international sales efforts in the future. We have
very limited experience in marketing, selling and supporting our solutions
abroad. Expansion of our international

                                       10
<PAGE>

operations will require a significant amount of attention from our management
and substantial financial resources. If we are unable to grow our international
operations successfully and in a timely manner, our business and operating
results could be harmed. In addition, doing business internationally involves
additional risks, particularly:

  . unexpected changes in regulatory requirements, taxes, trade laws and
    tariffs;

  . acceptance of the Internet and supporting technology standards;

  . restrictions on repatriation of earnings;

  . differing intellectual property rights;

  . differing labor regulations;

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

  . greater difficulty in staffing and managing foreign operations; and

  . fluctuating currency exchange rates.

If we are unable to protect our intellectual property, we may lose a valuable
asset, experience reduced market share, or incur costly litigation to protect
our rights.

   Our success depends, in part, upon our intellectual property rights. To
date, we have relied primarily on a combination of trade secret and trademark
laws, and nondisclosure and other contractual restrictions on copying and
distribution to protect our proprietary technology. Litigation to enforce our
intellectual property rights or protect our trade secrets could result in
substantial costs and may not be successful. Any inability to protect our
intellectual property rights could seriously harm our business, operating
results and financial condition. In addition, the laws of certain foreign
countries may not protect our intellectual property rights to the same extent
as do the laws of the United States. Our means of protecting our intellectual
property rights in the United States or abroad may not be adequate to fully
protect our intellectual property rights.

Third-party claims that we infringe upon their intellectual property rights
could be costly to defend or settle.

   Litigation regarding intellectual property rights is common in Internet-
related industries. We expect that Internet technologies and services may be
increasingly subject to third-party infringement claims as the number of
competitors in our industry segment grows and the functionality of products and
services in different industry segments overlaps. We may from time to time
encounter disputes over rights and obligations concerning intellectual
property. Although we believe that our intellectual property rights are
sufficient to allow us to market our solution without incurring third-party
liability, third parties may bring claims of infringement against us. These
claims may or may not have merit. Any litigation to defend against claims of
infringement or invalidity could result in substantial costs and diversion of
resources. Furthermore, a party making a claim could secure a judgment that
requires us to pay substantial damages. A judgment could also include an
injunction or other court order that could prevent us from selling our
solutions. Our business, operating results and financial condition could be
harmed if any of these events occurred.

   In addition, we have agreed, and may agree in the future, to indemnify
certain of our customers against claims that our solution infringes upon the
intellectual property rights of others. We could incur substantial costs in
defending ourselves and our customers against infringement claims. In the event
of a claim of infringement, we and our customers may be required to obtain one
or more licenses from third parties. We, or our customers, may be unable to
obtain necessary licenses from third parties at a reasonable cost, or at all.
Defense of any lawsuit or failure to obtain any potentially required licenses
could harm our business, operating results and financial condition.

                                       11
<PAGE>

We are in current litigation defending claims of improper use of our name and,
if not settled, could be time-consuming, costly to defend and result in
substantial liability.

   We are a defendant in a lawsuit pending in the U.S. District Court for the
Eastern District of Missouri brought by Bridge Information Systems, or Bridge.
Bridge alleges trademark infringement and related causes of action arising from
our use of 2Bridge. We have responded to the complaint with counterclaims
seeking a declaration of non-liability. Neither party has commenced discovery.
The court has scheduled a trial date for this matter during year 2001. Bridge
recently approached us to discuss an amicable resolution of the dispute. We
have indicated to Bridge that any settlement must allow us to use the name and
mark 2Bridge without any field of use restrictions. Although we are continuing
our discussions, it is too early to determine whether we will reach a
negotiated settlement. We intend to defend the case vigorously and believe that
it has a meritorious defense. However, there can be no assurance that we will
be free to continue using our name in its current form or will be free from
damages or liability arising from the use of our name.

If we become subject to service-related liability claims, they could be time-
consuming and costly to defend.

   Since our customers use our solution for mission-critical applications such
as communication, Internet commerce and collaboration, errors, defects or other
performance problems could result in financial or other damages to our
customers. They could seek damages for losses from us, which, if successful,
could have a material adverse effect on our business, operating results or
financial condition. Although our agreements with our customers typically
contain provisions designed to limit our exposure to service-related liability
claims, existing or future laws or unfavorable judicial decisions could negate
these limitation of liability provisions. We have not experienced any product
liability claims to date. However, a service-related liability claim brought
against us, even if unsuccessful, could be time-consuming and costly to defend
and could harm our reputation.

                         Risks Relating To Our Industry

Our market is subject to rapid technological change and our future success will
depend on our ability to meet the changing needs of our industry.

   Our market is characterized by rapidly changing technology, evolving
industry standards and frequent new product and service announcements. To be
successful, we must adapt to our rapidly changing market by continually
improving the performance, features and reliability of our solution. We could
incur substantial costs to modify our solution or infrastructure in order to
adapt to these changes. Our business could be harmed if we incur significant
costs without adequate results, or if we are unable to adapt rapidly to these
changes.

Continued adoption of the Internet as a method of conducting business is
necessary for our future growth.

   The market for Internet-based, business-to-business communication, commerce
and collaboration is relatively new and is evolving rapidly. Our future
revenues and any future profits depend upon the widespread acceptance and use
of the Internet as an effective medium for business-to-business communication,
commerce and collaboration. The failure of the Internet to continue to develop
as a commercial or business medium could harm our business, operating results
and financial condition. The acceptance and use of the Internet for business-
to-business communication, commerce and collaboration could be limited by a
number of factors, such as the growth and use of the Internet in general, the
relative ease of communication, commerce and collaboration on the Internet, the
efficiencies and improvements that the Internet provides, concerns about
transaction security and taxation of transactions on the Internet.

                                       12
<PAGE>

We depend on the speed and reliability of the Internet and our customers'
internal networks.

   The recent growth in Internet traffic has caused frequent periods of
decreased performance. If Internet usage continues to grow rapidly, its
infrastructure may not be able to support these demands and its performance and
reliability may decline. If outages or delays on the Internet occur frequently
or increase in frequency, business-to-business communication, commerce and
collaboration markets could grow more slowly or decline, which may reduce the
demand for our solution. The ability of 2Share to satisfy our customers' needs
is ultimately limited by and depends upon the speed and reliability of both the
Internet and our customers' internal networks. Consequently, the emergence and
growth of the market for our managed services depends upon improvements being
made to the entire Internet as well as to our individual customers' networking
infrastructures to alleviate overloading and congestion. If these improvements
are not made, the ability of our customers to utilize our solution will be
hindered, and our business, operating results and financial condition may
suffer.

Increased security risks of online commerce may deter future use of our
services.

   A fundamental requirement to conduct Internet-based, business-to-business
communication, commerce and collaboration is the secure transmission of
confidential information over public networks. Advances in computer
capabilities, new discoveries in the field of cryptography, or other
developments may result in a compromise or breach of the security features
contained in our services or the algorithms used by our customers and their
business partners to protect content and transactions on Internet eCommerce
marketplaces or proprietary information in our customers' and their business
partners' databases. Anyone who is able to circumvent security measures could
misappropriate proprietary, confidential customer information or cause
interruptions in our customers' and their business partners' operations. Our
customers and their business partners may be required to incur significant
costs to protect against security breaches or to alleviate problems caused by
breaches, reducing their demand for our solution. Further, a well-publicized
compromise of security could deter businesses from using the Internet to
conduct transactions that involve transmitting confidential information. The
failure of the security features of our services to prevent security breaches,
or well publicized security breaches affecting the Internet in general, could
significantly harm our business, operating results and financial condition.

Internet-related laws could limit the market for our services.

   Regulation of the Internet is largely unsettled. The adoption of laws or
regulations that increase the costs or administrative burdens of doing business
using the Internet could cause companies to seek an alternative means of doing
business. If the adoption of new Internet laws or regulations causes companies
to seek alternative methods for conducting business, the demand for our
solution could decrease and our business could be adversely affected.

                        Risks Relating To This Offering

Because certain existing stockholders own a large percentage of our voting
stock, other stockholders' voting power may be limited.

   Following the completion of this offering, it is anticipated that our
executive officers, directors and their affiliates will beneficially own or
control approximately   % of our common stock. In combination with entities
owning 5% or more of our outstanding shares of common stock, this group
currently beneficially owns 19,297,251 shares of common stock, or approximately
80.0% of the outstanding shares of our stock. As a result, if those
stockholders act together, they will have the ability to control all matters
submitted to our stockholders for approval, including the election and removal
of directors and the approval of any merger, consolidation or sale of all or
substantially all of

                                       13
<PAGE>

our assets. These stockholders may make decisions that are adverse to your
interests. See our discussion under the caption "Principal Stockholders" for
more information about ownership of our outstanding shares.

Future sales of our common stock may depress our stock price.

       shares of our common stock can be sold in the public market 180 days
after the offering. If substantial amounts of our common stock were to be sold
in the public market following this offering, the market price of our common
stock could fall. In addition, these sales could create the perception to the
public of difficulties or problems with our solution. As a result, these sales
also might make it more difficult for us to sell equity or equity-related
securities in the future at a time and price that we consider appropriate. For
a more detailed discussion of shares eligible for sale after the offering, see
"Shares Eligible for Future Sale".

We have broad discretion to use the offering proceeds, and the investment of
these proceeds may not yield a favorable return.

   The net proceeds of this offering are not allocated for specific purposes.
Thus, our management has broad discretion over how to use these proceeds, and
could spend most of them in ways with which our stockholders may not agree. The
proceeds may be invested in ways that do not yield favorable returns. See "Use
of Proceeds" for more information about how we plan to use our proceeds from
this offering.

Our securities have no prior market, and our stock price may decline after the
offering.

   Before this offering, there has not been a public market for our common
stock. An active public market for our common stock may not develop or be
sustained after this offering. The initial public offering price has been
determined by negotiations between representatives of the underwriters and
ourselves. The trading prices of many technology companies' stocks are at or
near historical highs and reflect price to earnings ratios substantially above
historic levels. We cannot be certain that these trading prices or price to
earnings ratios will be sustained. The trading market price of our common stock
may decline below our initial public offering price.

Internet-related stock prices are especially volatile and this volatility may
depress our stock price.

   The stock market, and specifically the stock prices of Internet-related
companies, has been very volatile. This volatility is often not related to the
operating performance of the companies. This broad market and industry
volatility may reduce the price of our common stock, regardless to our
operating performance. Due to this volatility, the market price of our common
stock could significantly decrease.

   Fluctuations in our common stock's price may affect our visibility and
credibility in the business-to-business eCommerce solutions market. In the
event of broad fluctuations in the market price of our common stock, you may be
unable to resell your shares at or above the offering price.

   Securities class action litigation has often been brought against companies
that experience volatility in the market price of their securities. Litigation
brought against us could result in substantial costs to us in defending against
a lawsuit and management's attention could be diverted from our business.

                                       14
<PAGE>

As a new investor, you will experience immediate and substantial dilution in
the value of the common stock.

   If you purchase shares of our common stock in this offering, you will incur
immediate and substantial dilution in pro forma net tangible book value. If the
holders of outstanding options and warrants exercise those options and
warrants, you will incur further dilution. See "Dilution" for a calculation of
the amount of dilution you will incur.

We have implemented certain anti-takeover provisions that could make it more
difficult for a third party to acquire us.

   Provisions of our certificate of incorporation and our bylaws, as well as
Delaware law, could make it more difficult for a third party to acquire us,
even if doing so would be beneficial to our stockholders. See "Description of
Capital Stock--Delaware Anti-Takeover Law and Certain Charter and Bylaws
Provisions" for a description of these provisions.

                                USE OF PROCEEDS

   Our net proceeds from the sale of     shares of common stock in this
offering at an assumed initial public offering price of $    per share, after
deducting estimated underwriting discounts and commissions and estimated
offering expenses, will be $   . If the underwriters' over-allotment option is
exercised in full, we estimate that our net proceeds will be approximately
$   million.

   Our principal reasons for engaging in this offering are to increase our
equity capital, create a public market for our common stock, facilitate future
access to the public equity markets and provide increased visibility in our
marketplace. We anticipate using the proceeds from this offering for working
capital and other general corporate purposes, including expansion of services
and operations personnel, technology research and development, and sales and
marketing personnel. The amounts that we actually expend on these matters will
vary significantly, depending on a number of factors, including future revenue
growth, if any, and the amount of cash we generate from operations. As a
result, we will retain broad discretion in the allocation of the net proceeds
of this offering. We may also consider acquisitions to enhance our solutions,
technologies or business. We currently have no commitments or agreements and
are not involved in any negotiations with respect to any acquisitions of
complementary products, technologies or businesses. Pending use of the net
proceeds of this offering, we intend to invest the net proceeds in interest
bearing, investment-grade securities.

                                DIVIDEND POLICY

   We have never declared or paid any cash dividends on our common stock or
other securities. We currently anticipate that we will retain all of our future
earnings for use in the expansion and operation of our business and do not
anticipate paying any cash dividends for the foreseeable future. In addition,
the terms of our line of credit arrangement restrict our ability to pay cash
dividends.

                                    DILUTION

   Our pro forma net tangible book value as of December 31, 1999, after giving
effect to the conversion of our outstanding preferred stock into common stock
upon completion of this offering and the sale of 743,200 shares of Series D
preferred stock for $7.2 million on March 10, 2000 and the sale of 300,000
shares of common stock for $1.6 million on March 8, 2000, was $16.6 million or
$0.70 per share of common stock. Pro forma net tangible book value per share
represents total tangible assets less total liabilities, divided by the number
of outstanding shares of common stock.

   Dilution in net tangible book value per share represents the difference
between the amount per share paid by purchasers of our common stock in this
offering and the net tangible book value per share of our common stock
immediately afterwards. After giving effect to our sale of the     shares of
common stock offered by this prospectus and after deducting estimated
underwriting discounts and commissions and estimated offering expenses payable
by us, our net tangible book value at December 31, 1999 would have been $
or $    per share. This represents an immediate increase in net tangible book
value to existing stockholders of $    per share and an immediate dilution to
new public investors of $    per share. The following table illustrates the per
share dilution:

   The above discussion and tables assume no exercise of stock options or
warrants outstanding as of December 31, 1999. As of December 31, 1999, there
were options and warrants outstanding to purchase a total of 1,698,907 shares
and 620,925 shares of our common stock with a weighted-average exercise price
of $1.13 and $2.96 per share. If any of these options or warrants are
exercised, there will be further dilution to new public investors. Please see

                            SELECTED FINANCIAL DATA
                     (in thousands, except per share data)

   The statements of operations data for the years ended December 31, 1997,
1998 and 1999 and the balance sheet data at December 31, 1998 and 1999, are
derived from our financial statements and related notes which have been audited
by Ernst & Young LLP, independent auditors, and are included elsewhere in this
prospectus. The balance sheet data at December 31, 1997 are derived from
audited financial statements not included in this prospectus. Historical
results are not necessarily indicative of future results. When you read this
selected financial data, it is important that you also read the financial
statements and the related notes included in this prospectus, as well as the
section of this prospectus titled Management's Discussion and Analysis of
Financial Condition and Results of Operations.

   In September 1992, Mr. Mansoor Zakaria, our Chief Executive Officer, founded
a California corporation which provided publishing and strategic consulting
services from its incorporation through December 31, 1996. These operations
were unrelated to 2Bridge's current operations. Revenues from these operations
were $693,000 for the year ended December 31, 1995 and $1.8 million for the
year ended December 31, 1996. The corporation had a net loss of $226,000 for
the year ended December 31, 1995 and had net income of $251,000 for the year
ended December 31, 1996. These financial results are derived from unaudited
financial statements not included in this prospectus. When we were funded in
January 1997 to develop our 2Bridge solution, this corporate entity was
retained. Accordingly, the results of operations for the corporation for the
years ended December 31, 1995 and 1996 are not meaningful for comparison
purposes with the results of operations for the three years ended December 31,
1999.

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

   The following Management's Discussion and Analysis of Financial Condition
and Results of Operations contains forward-looking statements based upon
current expectations that involve risks and uncertainties. The following
discussion should be read in conjunction with the financial statements and
notes included elsewhere in this prospectus. Our actual results and the timing
of certain events could differ materially from those anticipated in these
forward-looking statements as a result of certain factors, including those set
forth under "Risk Factors" and elsewhere in this prospectus.

   We provide comprehensive Internet-based solutions to create many-to-many
communication, commerce and collaboration eHubs for businesses. An eHub is an
Internet-based workspace where customers, partners, suppliers and employees can
simultaneously interact, access real-time business information, integrate
business processes and conduct eCommerce transactions. We believe our solutions
represent a new paradigm for eBusiness, and are designed to deliver secure,
real-time content and eCommerce capabilities from virtually any source to any
user, at any time.

   We received funding in January 1997 to develop our 2Share solution and were
a development stage company from that date through September 30 ,1998. During
this period we did not have significant revenues and our operating activities
were related primarily to designing, developing and testing our solution,
expanding our sales, marketing and services organizations, building our
corporate infrastructure, testing our technology in client environments,
establishing relationships with partners, customers and suppliers, and raising
capital. Since January 1997, we have incurred substantial research and
development costs and invested heavily in the expansion of our sales, marketing
and services organizations to support our long-term growth strategy. Our
headcount increased from 43 persons as of December 31, 1998 to 124 as of March
10, 2000. As a result of these expenses, we have incurred net losses in each
quarter since the quarter ended March 31, 1997 and as of December 31, 1999 had
an accumulated deficit of $27.9 million. We intend to continue expanding our
sales and marketing organizations and implementing significant marketing
programs to solidify our market position, gain name recognition, establish an
international presence and introduce new products and services. We also intend
to increase our research and development, sales and marketing, and general and
administrative organizations so that we can continue to enhance our solution
and deliver services that are beneficial to our customers. As a result of these
anticipated expenditures, we expect to incur net losses for the foreseeable
future.

   We focused our initial development efforts on an Internet software
application designed to allow our customers to construct customized eHubs. We
sold our solutions as stand-alone products and derived revenues from the
licenses, maintenance and support of the software application. We recognized
revenues from license agreements upon delivery and acceptance of our solution.
Services revenues were recognized as these services were performed. Maintenance
revenues were recognized ratably over the term of the support contract,
typically one year. In mid-1999 we recognized the opportunity to build upon our
initial software development efforts to deliver an eHub solution over an IP
network that we believe represents a new category of Internet-based solutions.
In August 1999, to better align our business model with our customers' needs,
we discontinued our license model and began selling our solution for recurring
fees. Our last license revenues were recognized for the three months ending
September 30, 1999.

   Our revenues will primarily consist of recurring fees, which are based upon
the complexity of the eHub determined by the number of different application
services, information sources and other related add-on services. Customers
contract for periodic recurring fees which cover all services related to our
2Share-enabled eHubs.


                                       20
<PAGE>

   Revenues during the implementation period are recognized ratably as services
are performed. Recurring fees are recognized over the term of the agreement and
add-on services are recognized as services are performed. Under our recurring
fee-based model, we do not expect to generate significant deferred revenues,
but payments made in advance of delivering our solution will be recorded as
deferred revenues.

   We offer our 2Share solution and related services primarily through a direct
field force of business advisors based in the United States. We also have
business specialists who are internal sales personnel that assist our advisors
with lead generation and customer qualification. In addition, we have recently
entered into marketing arrangements to enhance our indirect sales channels.

   We believe that period-to-period comparisons of our operating results should
not be relied upon as indicative of future performance. Our prospects must be
considered in light of the risks, expenses and difficulties frequently
encountered by companies in early stages of development, particularly companies
in new and rapidly evolving markets. There can be no assurance we will be
successful in addressing such risks and difficulties. Although we have
experienced revenue growth recently, this growth may not continue. In addition,
we may not achieve or maintain profitability in the future.

Results of Operations

   We did not recognize any revenues in 1997 since our solution was not yet
commercially available. We incurred operating expenses in 1997 primarily
related to increases in headcount in research and development, sales and
marketing and general administrative organizations.

   Revenues

   Prior to September 30, 1999, our revenues were derived from the sale of
software licenses, maintenance and consulting services. After that date, we
began offering our solutions and services through a recurring fee-based model.
Our revenues were $717,000 for the year ended December 31, 1998 and $3.6
million for the year ended December 31, 1999. The increase resulted from the
increase in the number of customers as well as in the penetration of our
existing customers. J.P. Morgan & Co. Incorporated, The McGraw-Hill Companies
Inc. and SAP AG each accounted for over ten percent of our revenues in 1998.
J.P. Morgan & Co. Incorporated, The McGraw-Hill Companies Inc. and Schroders &
Company Inc. each accounted for over ten percent of our revenues in 1999.

   Cost of Revenues

   Our cost of revenues includes costs related to network hardware,
compensation and related overhead costs for personnel engaged in providing our
2Share solution, as well as costs for third parties contracted to provide
services to our customers. A portion of our indirect compensation and related
overhead costs is allocated to cost of revenues. We expect the allocation of
indirect costs to increase in absolute dollars based on increased revenues
derived from our 2Share solution. Cost of revenues increased from $184,000 for
the year ended December 31, 1998 to $1.3 million for the year ended December
31, 1999. This increase resulted from cost incurred to support our increasing
revenues received from our growing customer base.

   Operating Expenses

   Sales and Marketing. Our sales and marketing expenses consist primarily of
salaries and related costs for sales and marketing personnel, sales commissions
and other marketing activities. Sales and marketing expenses increased from
$3.3 million for the year ended December 31, 1998 to $9.4 million for the year
ended December 31, 1999. This increase was due to an increase of $1.7 million
in compensation expenses and increased spending of $4.4 million on advertising
and marketing programs.

   Research and Development. Our research and development expenses consist
primarily of personnel and related costs. Research and development expenses
increased from $3.0 million in the year ended December 31, 1998 to $3.5 million
for the year ended December 31, 1999. This increase was primarily due to an
increase in headcount and related personnel costs. Technological feasibility of
the software component of our solution is generally not established until
substantially all product development is complete. Historically, software
development costs eligible for capitalization have been insignificant, and all
costs related to research and development have been expensed as incurred.


   General and Administrative. Our general and administrative expenses consist
primarily of compensation and related costs for our executive, finance and
administrative personnel and other related expenses. General and administrative
expenses increased from $1.5 million for the year ended December 31, 1998 to
$5.0 million for the year ended December 31, 1999. This increase was primarily
due to increased compensation and related benefits associated with additional
personnel costs of $841,000 and increased costs associated with expanded
facilities, depreciation and overhead expenses of $2.5 million.

   Amortization of Deferred Stock-Based Compensation. Amortization of deferred
stock-based compensation represents the amount of amortization related to the
difference between the exercise price of options granted and the deemed fair
market value of the underlying common stock on the date of the grant. During
the years ended December 31, 1998 and 1999, we recorded deferred compensation
of $16,000 and $8.5 million, in connection with stock option grants to
employees. We are amortizing this amount over the vesting periods of the
applicable options, resulting in amortization expense of $54,000 for the year
ended December 31, 1998 and $1.3 million for the year ended December 31, 1999.


   Interest and Other Income

   Interest and other income was $211,000 for the year ended December 31, 1998
and $298,000 for the year ended December 31, 1999. Interest income during each
year primarily resulted from interest earned on the proceeds from private
placements of our preferred stock.

   Interest Expense

   Our interest expense was $182,000 for the year ended December 31, 1998 and
$674,000 for the year ended December 31, 1999. The increased interest expense
resulted from additional borrowings and higher capital lease obligations during
the year ended December 31, 1999.

Income Taxes

   There was no provision for federal or state income taxes for any period
since inception due to our operating losses. At December 31, 1999, we had net
operating loss carryforwards for federal income tax purposes of approximately
$25.0 million, which will expire in years 2010 through 2019 if not utilized.
Utilization of our net operating loss carryforwards may be subject to
substantial annual limitation due to ownership change provisions provided by
the Internal Revenue Code and similar state provisions. Such an annual
limitation could result in the expiration of the net operating loss
carryforwards before utilization. A valuation allowance has been established
and, accordingly, no benefit has been recognized for our net operating losses
and other deferred tax assets. The net valuation allowance increased by
approximately $3.0 million and $5.8 million during the years ended December 31,
1998 and 1999.

Quarterly Results of Operations

   The following table sets forth unaudited statement of operations data for
the five quarters following the general availability of our solution in
September 1998. This data has been derived from our unaudited financial
statements that have been prepared on the same basis as the audited financial
statements and, in the opinion of our management, include all adjustments,
consisting of normal recurring adjustments, necessary for a fair presentation
of the information when read in conjunction with our financial statements and
related notes. Our quarterly results have been in the past and may in the
future be susceptible to significant fluctuations. As a result, we believe that
results of operations for interim periods should not be relied upon as any
indication of the results to be expected in any future period.

</TABLE>

   Our revenues have increased in every quarter since the introduction of our
2Share platform in September 1998. These increases are attributable to the
increased market awareness and acceptance of the 2Share solution and the
penetration of our existing customer base. In the fourth quarter of 1999, we
began offering our 2Share solution exclusively on a recurring fee-based
business model which resulted in the allocation of significantly higher
compensation and related overhead costs to cost of revenues.

   Operating expenses have generally increased each quarter because of
increased staffing in our sales and marketing, research and development and
general and administrative organizations. Research and development costs
decreased during the three months ended March 31, 1999 relative to the three
months ended December 31, 1998 in which we expensed purchased development costs
of $250,000. In addition, sales and marketing expenses increased significantly
for the three months ended September 30, 1999 due to increases in marketing
expenses related to national brand awareness and lead generation.

   Our quarterly operating results have fluctuated significantly in the past,
and will continue to fluctuate in the future, as a result of a number of
factors, many of which are outside our control. These factors include:

  . the amount and timing of operating costs relating to the expansion of our
    business, operations and infrastructure;

                                       23
<PAGE>

  . the number and timing of new hires, particularly with respect to services
    and operations personnel;

  . the timing of our sales cycles;

  . our ability to meet scheduled eHub implementations; and

  . our utilization rate for our services and operations personnel.

Liquidity and Capital Resources

   Through December 31, 1999, we have funded our operations primarily through
sales of equity securities with net proceeds of $33.3 million, and, to a lesser
extent, the use of long-term debt and equipment leases. We have also raised
funds from short-term debt. Our short-term debt, including the current portion
of our capital lease obligations, was $5.4 million at December 31, 1999. Our
sources of liquidity, as of December 31, 1999 consisted principally of cash and
cash equivalents of $8.8 million.

   Net cash used in operating activities was $7.0 million for 1998 and $16.9
million for 1999. For these periods, net cash used by operating activities was
primarily for the funding of ongoing operations.

   Net cash used in investing activities was $936,000 for 1998 and $1.5 million
for 1999. Our investing activities have consisted of purchases of property and
equipment. We finance the acquisition of property and equipment, which consists
mainly of furniture and fixtures and computer hardware and software for our
increasing employee base as well as for our management information systems,
primarily through capital leases. We expect to experience an increase in our
capital expenditures and lease commitments consistent with our anticipated
growth in operations, infrastructure and personnel.

   Net cash provided by financing activities was $11.8 million in 1998 and
$22.3 million for 1999. For 1998, proceeds from financing activities were
primarily received from the private sale of preferred stock of $10.1 million
and $2.5 million from the sale and lease back of property and equipment. In
1999, proceeds provided by financing activities were primarily from the sale of
preferred stock of $20.0 million and $5.1 million from short-term borrowings,
offset in part by principal payments on capital lease obligations and long-term
debt of $2.7 million.

   We expect to experience significant growth in our operating expenses in the
future, particularly in sales and marketing and research and development in
order to execute our business plan. As a result, we anticipate that these
operating expenses, as well as planned capital expenditures, will constitute a
material use of our cash resources. In addition, we may utilize cash resources
to fund acquisitions or investments in complementary businesses, technologies
or product lines. We believe that the net proceeds from the sale of common
stock in this offering will be sufficient to meet our operational and capital
expenditure requirements for at least the next 12 months. Thereafter, we may
find it necessary to obtain additional equity or debt financing. In the event
additional financing is required, we may not be able to raise it on acceptable
terms or at all.

Year 2000 Issues

   We did not experience any significant problems associated with Year 2000
issues, and we are not aware that any of our suppliers or vendors experienced
any such problems.

Interest Rate 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
investment portfolio and on the

                                       24
<PAGE>

increase or decrease in the amount of interest expense we must pay with respect
to our outstanding debt instruments.

   The risk associated with fluctuating interest expense is limited to the
exposure related to those debt instruments which are tied to market rates. We
do not use derivative financial instruments in our investment portfolio. We
ensure the safety and preservation of our invested principal funds by limiting
default risks, market risk and reinvestment risk.

   We mitigate default risk by investing in safe and high-credit quality
securities. A hypothetical increase or decrease in market interest rates by 10%
from the market rates in effect at December 31, 1999 would not cause the fair
value of our cash and cash equivalents or the expense paid with respect to our
outstanding debt instruments to change by a material amount. Declines in
interest rates over time will, however, reduce our interest income while
increases in interest rates over time will increase our interest expense.

Overview

   We provide comprehensive Internet-based solutions to create many-to-many
communication, commerce and collaboration eHubs for businesses. An eHub is an
Internet-based workspace where customers, partners, suppliers and employees can
simultaneously interact, access real-time business information, integrate
business processes and conduct eCommerce transactions. We believe our solutions
represent a new paradigm for eBusiness, and are designed to deliver secure,
real-time content and eCommerce capabilities from virtually any source to any
user, at any time.

   Our solutions represent a new category of business-to-business platforms
designed to deliver dial-tone-like reliability and functionality, which we
refer to as Web-tone. We believe our Web-tone business model is better aligned
with our customers' needs because it is based on recurring fees for solutions,
services and transaction capabilities instead of a large one-time capital
investment usually associated with software license purchases. Our business
model provides our customers with the flexibility to adjust the type of
services they receive from us in response to their changing business needs and
provides us with the incentive to innovate and serve them since we share in
their long-term success.

   Our eHub platform, 2Share, can be rapidly adopted by our customers to
construct customized eHubs that require no client application other than a
browser to create a primary business network. 2Share is an open standard
platform based on Java and XML (eXtensible Markup Language), and is provided
with comprehensive managed services which are deployed by customers in a
service-like fashion. With 2Share, a company can bridge multiple constituents
inside and outside the organization and empower each user to share, manage,
target and personalize valuable information from disparate corporate databases,
email exchanges, isolated desktops, and internal and external Web sites and
networks. Our solutions enable not only the collaborative exchange and
management of information, but also eCommerce transactions that result from
this collaboration.

   2Share empowers our customers, who are highly dependent on real-time
information exchange, to rapidly and seamlessly develop customized eHubs. We
believe our solutions create value by enabling firms to strengthen business and
employee relationships, improve time to market, increase revenue and new market
opportunities, and improve return on investment of existing corporate assets.
Since the introduction of 2Share in 1998, we have delivered our solutions to
customers in a number of strategic industries, including J.P. Morgan & Co.
Incorporated, The McGraw-Hill Companies, SAP AG, Schroders & Company, and Visa
USA.

Industry Background

  Evolution of the Internet as a Communication, Commerce and Collaboration
 Platform

   The Internet has become the fastest growing universal communications and
commerce medium in history. It is changing the way businesses interact and
transact with customers, partners, suppliers and employees. The communications
and information exchange capabilities of the Internet make it a natural
platform for collaboration and commerce for both businesses and consumers. Over
the past few years, the Internet has been used as a platform to publish massive
amounts of content. International Data Corporation estimates that the number of
Web content pages or URLs will grow from 2.2 billion in 1999 to over 16.5
billion in 2003. Over the same period of time, the Internet has been
increasingly leveraged as a primary sales and distribution channel by
businesses. Gartner Group estimates that business-to-business eCommerce over
the Internet will grow from $145 billion in 1999 to $7.3 trillion in 2004.
Moreover, Forrester Research also estimates that business-to-business eCommerce
will account for more than 93% of U.S. eCommerce transactions by 2004.

  Emergence of the Internet as a Platform for a Primary Business Network

   The impact of the Internet on traditional commerce models extends far beyond
the dollar value of commerce activity conducted over the Internet and has led
to the emergence of entirely new business models. The Internet has enabled
companies to create new revenue opportunities, provide more useful information,
streamline complex business processes, lower costs and increase productivity in
the form of business-to-business solutions. To remain competitive, companies
are beginning to leverage the Internet as a primary network platform for
interaction that can span organizational boundaries and represent new, more
open organizational structures. Business users worldwide are beginning to rely
on the Internet to collaborate, interact and conduct business. In particular,
businesses recognize the strategic importance of using the Internet to
strengthen relationships with customers, partners, suppliers and employees.

  Traditional Methods of Business-to-Business Communication, Commerce and
 Collaboration

   Traditionally, business-to-business communication, commerce and
collaboration has been conducted by means of phone, paper, fax and face-to-face
meetings. Increasing challenges in addressing the need for real-time
communications and transactions have led companies to adopt information
technology products and services such as databases, client/server applications,
video conferencing and e-mail. More recently, some companies have tried to
address their need for real-time communications, commerce and collaboration by
using software tools and in-house developers or consultants. However, the
realizable benefits of these custom systems tend to be uncertain due to the
challenges of integration with existing technology infrastructure and
adaptability for use with future technologies.

   In addition, traditional information technology products and services
generally limit communications to a one-to-one basis between two parties, and
cannot support a real-time network-based or many-to-many form of interaction
that can span organizational boundaries. Traditional products and services
generally cannot scale either in terms of users, transaction volumes or
geography and have typically been deployed under a software license model,
which involves significant one-time capital outlays and often limits ongoing
relationships.

   The limited communication capabilities of traditional technology products
and services have inhibited the migration of complex, commerce processes to the
Internet. While businesses have adopted the Internet as an effective channel
for transaction execution, the information-centric communication and
collaboration processes that both precede and follow a transaction have been
difficult for businesses to move to the Internet.

  Challenges Facing Business-to-Business Communication, Commerce and
 Collaboration

   Traditional solutions for addressing the communication, commerce and
collaboration needs of today's fast paced Internet economy offer only a partial
solution and have significant drawbacks. These drawbacks include:

  . Management and Information Control. Traditional solutions do not allow
    users to effectively access, organize, control, integrate, customize and
    share information from disparate sources inside and outside an
    organization such as corporate databases, e-mail exchanges, desktops,
    networks and internal and external Web sites;

  . Scope of Communication. Traditional technologies have been unable to
    scale and extend beyond one-to-one interactions to many-to-many
    communication, commerce and collaboration among customers, partners,
    suppliers and employees through an easily accessible primary business
    network;

  . Time to Market. Current products and services typically involve long
    development and implementation cycles, a dedicated technical staff and
    integration risk;

                                       27
<PAGE>

  . License Business Model. Traditional software solutions require
    significant one-time capital investments due to vendors' software license
    models; and

  . Proprietary Technology. Traditional software products and services have
    generally been unable to adapt to next-generation Internet architecture,
    are often incompatible with existing technology infrastructure and are
    dependent on proprietary technologies which are difficult to customize,
    and require skilled and hard-to-find technology resources.

  Opportunities for Business-to-Business Communication, Commerce and
 Collaboration

   The ubiquity and extensive adoption of the Internet enables it to serve as a
foundation for widespread business-to-business interactions which can bridge
companies and their customers, partners, suppliers and employees. These
interactions, which include business-to-business communication, commerce and
collaboration, often require integrating massive amounts of disparate
information and joining together hundreds or thousands of business users,
inside and outside the enterprise. Companies require an Internet-based solution
that can access, integrate, customize and share any type of information for any
user at any time, while enabling collaboration and eCommerce transactions.

   As the Internet has evolved, solutions have emerged which have accelerated
the use of the Internet as a primary business network. Early solutions have
included eBusiness portals, or Web sites for employees or customers that serve
as gateways for externally published content, services and basic eCommerce
transactions. More recent solutions include vertical eMarketplaces, or dynamic
trading hubs, that bring together multiple buyers and sellers and are operated
by neutral third parties with deep industry domain expertise. We believe that
the next stage of the Internet's evolution will be marked by the widespread
deployment of solutions to create many-to-many communication, commerce and
collaboration eHubs for businesses. An eHub is an Internet-based workspace
where customers, partners, suppliers and employees can interact, access real-
time business information, integrate business processes and conduct eCommerce
transactions.

   eHubs facilitate collaboration across disparate parties by integrating
shared business information and processes into one common interface and
permitting eCommerce transactions. Any industry that requires real-time
information exchange and collaboration among many disparate parties may benefit
from eHubs, including financial services, media and publishing, high-technology
and information services. As eHubs are adopted by companies, we believe they
will proliferate organically as one company's eHub extends through its
customers, partners and suppliers to form other eHubs. These compounding
benefits are based upon the principle of network effects in which the value of
a network becomes greater to each individual user as another user joins the
network. This network effect will drive the formation of a new communication
paradigm as one-to-one interactions over traditional networks, such as
telephone or email systems, are transformed into many-to-many interactions
across networks of eHubs.

   eHubs provide several potential benefits including enhanced operating
efficiency and employee productivity, opportunities for increased revenue and
improved profits and strengthened relationships with customers, partners,
suppliers and employees. A comprehensive communication, commerce and
collaboration eHub should, irrespective of existing technology infrastructure:

  .  enable many-to-many interactions;

  .  support real-time exchange of decentralized and personalized
     information;

  .  allow reliable and secure transactions between all parties using the
     eHub; and

                                       28
<PAGE>

  .   integrate cross-organizational processes and workflow.

   An eHub solution should be aligned with a company's operating and financial
needs by charging a recurring fee for solutions and services instead of a
significant one-time capital outlay usually associated with software license
purchases. To gain a competitive advantage in today's Internet economy,
companies and their customers, partners, suppliers and employees are in need of
eHub solutions.

The 2Bridge Solution

   We provide a comprehensive Internet-based eHub solutions that create many-
to-many communication, commerce and collaboration eHubs for businesses. Our
solutions provide business users inside and outside the enterprise the ability
to access real-time, mission-critical business information, integrate shared

  2Share Features

   Our 2Share solution is designed to extend a company's existing information
and communication processes to an Internet-based primary business network and
facilitate eCommerce transactions by:

  . providing information and transaction access, from any source and in any
    format, while being easy enough for any Internet-based business user to
    have control over production, management and distribution of mission-
    critical information and transactions to any other Internet-based user,
    at any time;

  . permitting extensive customization and personalization by individual
    users and allowing them to filter, create, capture, update, share and
    view vital information;

  . supporting permission-based management of information and transaction
    flows to any selected subset of users, or allowing a group of business
    partners to interact in an environment specifically designed to fit their
    needs;

  . allowing round-the-clock access and management of mission-critical
    information and business processes from a variety of devices;

  . maintaining open standards and architecture and supporting multiple
    operating system platforms such as Microsoft NT and Sun Solaris, while
    allowing easy integration and providing extended functionality with other
    existing technologies and services, such as enterprise software
    applications, news feeds, calendaring and real-time Web conferencing; and

  . enabling rapid deployment and ease of use, usually with minimal training.

   We believe our 2Share solution represents a new category of Internet
solutions designed to deliver dial-tone-like reliability and functionality,
which we refer to as Web-tone. We offer our Web-tone service for recurring fees
instead of significant one-time capital investments usually associated with
software license purchases. For additional fees, our customers can also receive
add-on services, such as specialized modules, including eCommerce capabilities,
management and premium service arrangements, and custom design and development
services. Unlike other solutions which involve a substantial one-time license
fee, our fee structure does not require a significant initial capital outlay
and provides our customers the flexibility to adjust the type of services they
subscribe

                                       29
<PAGE>

to in response to their changing business needs. In addition, our solution is
designed to deliver dial-tone-like reliability and functionality. Our solution
is an open standard platform based on Java and XML, provided with comprehensive
managed services which are deployed by customers in a service-like fashion. Our
eHub platform enables real-time, interactive communication, commerce and
collaboration among customers, partners, suppliers and employees, regardless of
their existing technology infrastructure.

   We believe our solution offers our customers the following benefits:

     Strengthened Business Relationships. Our solution allows our customers
  to more effectively bridge and strengthen their customer, partner, supplier
  and employee relationships by improving the speed and efficiency of
  communication, commerce and collaboration without changing existing work
  processes.

     Improved Time to Market. Our customers' eHubs typically can be
  implemented in just days to weeks versus the months it may take for
  internally developed or third-party solutions.

     Increased Revenue and New Market Opportunities. By improving the overall
  experience for customers through a dynamic business partnership, our
  solution provides our customers with cross-selling opportunities to their
  customers, partners and suppliers and enhances market competitiveness.

     Customizable and Scalable eHubs. Our solution is a scalable platform
  which can evolve with changing business or infrastructure needs over time,
  permitting the rapid addition of users, new features and services. In
  addition, our solution is designed to be easily adaptable regardless of the
  existing technology infrastructure or business processes.

     Improved Return on Investment (ROI) of Existing Systems. Our solution
  leverages a company's existing systems, which may previously have been
  isolated or difficult to access, and increases employee productivity. It is
  also designed to allow users to gain real-time access to mission-critical
  business information needed from any external source at any time.

Our Strategy

   We believe our solution represents a new paradigm for many-to-many
interactions, business-to-business information exchange and eCommerce
transactions. Our objective is to be the leading provider of comprehensive
Internet-based solutions that create many-to-many communication, commerce and
collaboration eHubs. To implement our strategy, we intend to:

     Leverage our Web-tone Delivery Model. Rather than charging large one-
  time license fees that require costly third-party consulting services and
  substantial IT department involvement, we deliver our solutions based on a
  one-time implementation fee followed by recurring fees. For additional
  fees, our customers can receive add-on services and specialized
  applications. This cost structure allows our customers to purchase our eHub
  services and scale them as needed. We believe our business model creates a
  partnership with our customers and is better aligned with their long-term
  business and financial objectives. Moreover, we believe our Web-tone
  delivery model will support the organic growth of eHub networks as it
  permits the rapid addition of new users and facilitates the proliferation
  of eHubs beyond our existing customers.

     Establish 2Bridge as a Leading Global Brand Enabling eHub Solutions. We
  plan to establish 2Bridge as the industry-standard platform on which to
  build eHubs. We intend to promote our brand to create strong penetration
  among strategic vertical markets. We believe that strong brand awareness,
  combined with our existing customer base, will give us a competitive
  advantage in our market. We also anticipate that the growth of the Internet
  internationally will present significant opportunities to extend the global
  reach of our solutions.

                                       30
<PAGE>

  We intend to expand globally by pursuing strategic partnerships and sales
  efforts in Asia and in Europe.

     Broaden Adoption of 2Share Throughout Our Existing Customer Base. We
  plan to expand the footprint of our solution throughout our existing
  customer base. We have designed our solution to enable our customers to
  deploy and scale their eHubs rapidly. Our solution is designed for
  virtually all business users throughout an organization and requires little
  or no training. Our customers are able to quickly realize its benefits and
  are motivated to adopt our solution broadly throughout the entire
  organization. As a result, we believe our current customers alone represent
  a significant growth opportunity.

     Target Strategic Markets. We plan to grow by targeting strategic markets
  where information and collaboration are critical, including financial and
  information services. We believe participants in these markets require the
  integration of complex information and processes in order to make effective
  business decisions. As our customers use our solutions across their network
  of customers, suppliers, partners and employees, other participants become
  aware of and may begin using our solutions. This experience can create a
  powerful multiplier effect across our target markets.

     Build Strategic Alliances to Strengthen Our Market Position and
  Offering. We intend to continue to develop strategic alliances with leaders
  in the content, technology and Internet business landscape. Through these
  third-party relationships we plan to offer additional value-added features
  such as enterprise software integration, news feeds, calendaring and real-
  time Web conferencing. We will also continue to pursue specific
  relationships with other Internet technology providers, Internet hosting
  companies and Internet service providers. We believe these relationships
  will accelerate the adoption of our solutions, increase our brand
  recognition and improve penetration of our target markets.

Our Solutions and Services

   Our 2Share solution enables our customers to deploy eHubs and bridge
customers, partners, suppliers and employees, irrespective of their existing
technology infrastructure and business processes. In addition, our 2Share
solution provides a flexible eHub platform which addresses our customer's
changing business needs and the ever-expanding potential of the Internet.

   Our solutions and services include the following features:

 Collaboration

     WorkCenter. At the heart of 2Share is the WorkCenter. WorkCenter is a
  browser-based module that allows business users to create a powerful
  network of eHubs that deliver meaningful and compelling information and
  transactions to selected audiences without the need for extensive technical
  training.

     InfoCenter. The InfoCenter is a browser-based module where content and
  workflow created in the WorkCenter is viewed. 2Share separates the delivery
  of content to an eHub from its construction to facilitate customized
  information delivery. A single item of content or transaction can be
  delivered to multiple audiences with a different look, feel and context
  setting for each user group.

 Customized Information Delivery

     Targeted Home Sites. Home Sites are customized points of entry into an
  eHub targeted at specific users' needs. Using 2Share, users can create
  thousands of targeted Home Sites that meet the needs of specific user
  groups, both inside and outside an organization. This feature is

                                       31
<PAGE>

  particularly valuable for the creation of business-to-business customer
  service eHubs which enable our customers to better serve and retain their
  customers.

     Personalization. 2Share supports personalized pages with content
  organized and presented according to user preferences. 2Share's
  personalization component, called MyView, serves as a single access point
  for data existing on the 2Share system and for external data including
  legacy systems and Internet links.

     Conversion to HTML. 2Share converts over 200 file formats to standard,
  browser-accessible formats such as HTML thereby making Internet site
  creation accessible to business users with no specialized training.

     Security. 2Share provides a secure repository for user information.
  Access to information is controlled through support for industry standard
  authentication and encryption protocols. Additionally, each user's login
  determines the specific information available to be viewed and modified.

     Search. 2Share helps customers sort and find information. 2Share content
  is tagged with user-defined metadata including, keyword, site name, site
  description, and author name. 2Share's search component enables the easy
  location and retrieval of all 2Share content.

     Workflow. 2Share supports information supply chain workflow. Role
  assignment can be used to guarantee that content is routed through
  customer-designated approval processes before becoming a viewable 2Share
  site.

     Threaded Discussion Groups. 2Share supports dynamic interaction through
  threaded discussion groups, which can be embedded in user-defined locations
  within 2Share sites. Threaded discussion groups encourage impromptu
  communication among site visitors.

 Extensibility

     Connection to External Systems. 2Share provides connectivity to
  customers' existing applications and databases, including legacy systems,
  to enable the display of information from those systems and the integration
  of business processes within customers' eHubs.

     Third-Party Product Integration. 2Share enables the integration of
  third-party product offerings to provide customers with complete solutions
  for their communication, commerce and collaboration needs.

 Value-Added Services

   We form relationships with our customers to ensure that they are using the
latest Internet technologies to meet their needs. As part of our complete eHub
solution, we offer several complementary business services to our customers
such as:

  . Client Technology Services which deliver customized business solutions,
    including site design and information architecture development, utilizing
    the technical expertise and business knowledge of our professionals;

  . Creative Services which provide creative strategy and direction based
    upon client business goals and their business model; and

  . Solutions and Development Services which may include individual teams
    assigned to customer projects to manage the eHub from inception to
    implementation.

   We currently have services personnel located in San Francisco, New York and
New Jersey, and we plan to add personnel in London, England and Bombay, India
during the second quarter of 2000.

 Customer Care

   We believe that offering a superior level of customer service is essential
for our long-term relationship with our customers and our success. Customer
service is a standard feature in our offerings and available to all of our
customers. We offer our customers a choice of several levels of support, which
is included in the recurring fee. Our support provides dependable and timely
resolution of customers' technical inquiries. Our customers can also access our
online customer care portal.

Customer Case Studies

 J.P. Morgan & Co. Incorporated

   J.P. Morgan & Co. Incorporated is a leading financial services firm. Certain
of its subsidiaries use 2Share to keep their professionals in multiple
locations in the U.S. and Europe abreast of real-time portfolio management
information and to provide superior and consistent advice to its clients.

   To provide this level of advice, J.P. Morgan's professionals needed real-
time access to vast amounts of information that existed in a variety of
disparate data sources.

   Our initial eHub solution was implemented in just 26 days, and with 2Share,
J.P. Morgan's professionals now have real-time access, via a standard Web-
browser, to consolidated, consistent and up-to-the-minute information. User
acceptance was high and the solution was rolled out quickly with on-going
training.

 The McGraw-Hill Companies, Inc.

   The McGraw-Hill Companies, a global publishing, financial, information and
media services company, wanted to create an industry-specific portal for the
aviation industry. McGraw-Hill needed to consolidate seven existing Web sites
serving the aerospace industry into a single eHub where content no longer had
to be manually updated using HTML programmers.

   McGraw-Hill selected 2Share to create its eHub, AviationNow, to collaborate
and publish articles and news stories in a more timely manner via a real-time
editorial process without the need for technical programming support.

   The AviationNow eHub provides twice-hourly updates on all late-breaking news
to the aerospace industry. Using 2Share, authors and editors log in and upload
and/or publish their stories from around the world. Some authors email their
copy directly to AviationNow where it is edited and published by business users
of the system. In addition to providing timely news stories, this eHub also
provides several reference and community functions such as the World Aviation
Directory, aircraft and spacecraft specifications, eCommerce capabilities, and
a forum to discuss aerospace-related topics. AviationNow currently enjoys over
12,000 visitors per day and over 1.4 million page views.

 SAP AG

   Based in Walldorf, Germany, SAP AG is the market leader of inter-enterprise
software solutions. As a means of communicating with its geographically
dispersed workforce, SAP frequently produces and distributes newsletters
worldwide containing critical marketing and customer information. Prior to
implementing 2Share, SAP used a manual process to deliver these newsletters.

   Today, SAP is able to deliver timely marketing information with their 2Share
system. Implementing 2Share enabled a small group of SAP employees to quickly
and efficiently create and distribute their newsletters in real-time to an
audience of over 300 users worldwide.

Sales and Marketing

   We sell 2Share and related services primarily through a direct field force
of business advisors based in the United States. We also have business
specialists who are inside sales personnel that assist our advisors with lead
generation and customer qualification. In addition, we have recently entered
into marketing arrangements to enhance our indirect sales channels. As of
February 29, 2000 our sales and marketing group consisted of 30 professionals
located in our headquarters in San Francisco, California and our regional
offices in New York, New York; Chicago, Illinois; Washington, D.C.; Princeton,
New Jersey; and Houston, Texas. We plan to expand our sales and marketing group
through aggressive recruiting efforts.

   Our marketing programs have been set up to establish our 2Share solution as
the industry-standard platform that enables eHubs and to generate significant
sales leads for our sales force to pursue. We use a broad mix of programs to
accomplish these goals including television and print advertising, press and
analyst briefings, e-mail campaigns, Web banners, Web sponsorships, outbound
telemarketing, industry trade shows and educational seminars. Additionally, to
support sales, we intend to produce high quality materials for prospective
customers including product overview brochures, technical briefs, white papers,
presentations and 2Share demonstrations.

Technology

   2Share incorporates a Java and XML-based open standard platform which
enables real-time interactions among customers, partners, suppliers and
employees regardless of existing technology infrastructure. Key aspects of our
architecture include the following:

  . Java-based architecture, which provides a solid foundation upon which to
    build our flexible component-based solution.

  . platform independence, which permits 2Share to support different
    operating systems like Windows NT or Sun Solaris, Web applications
    servers and databases.

  . browser-based access, which requires no user, or client-based software
    and relies exclusively on HTML and Java Script to enable all user
    interactions.

                                       34
<PAGE>

   In addition, the 2Share platform provides a powerful pluglet architecture.
2Share pluglets are server-side Java applications that provide access to
information residing both inside and outside of the 2Share system. Some common
pluglets pull data from relational databases, email systems and file systems,
while other pluglets provide discussion group functionality and site navigation
capabilities. Pluglets provide three major capabilities:

  . connections to data sources and metadata;

  . content conversion to multipurpose information types (typically HTML);

  . business user-focused interface that allows users to easily manage
    information and business processes.

   Pluglets deliver an extensible framework that allows new information sources
and workflow to be added to 2Share in a seamless manner. Below is a partial
list of 2Share pluglets:

Research and Development

   We have invested significantly in research and development to enhance our
current solution and develop new solutions. Our research and development
expenses were $3.0 million and $3.5 million for the year ended December 31,
1998 and 1999. As of March 10, 2000 our research and development organization
consisted of 24 employees who are also responsible for development, quality and
assurance testing, documentation, release and maintenance, and overall
execution of our development strategy. We intend to continue to expand and
enhance the capabilities of our 2Share platform, as well as develop and extend
our eHub solution offerings, in order to provide our customers with
comprehensive, secure and flexible eHubs.

Competition

   The market for many-to-many communication, commerce and collaboration
solutions is a new market, rapidly changing, intensely competitive and is
likely to become more competitive as the number of entrants and new
technologies increases. While we are not aware that any of our

                                       35
<PAGE>

competitors or potential competitors currently produces a solution that is
substantially similar to ours, we are subject to current or potential
competition from the following:

  . custom development efforts from in-house information technology
    resources, and from third-party systems integration and technology
    services companies.

  . suppliers of groupware, knowledge management and document management
    solutions such as IBM;

  . software companies that address narrower areas of Web site creation, such
    as the aggregation of data sources into a central location;

  . content personalization software and traditional and eBusiness consulting
    companies such as Broadvision and Vignette;

   We believe that the principal competitive factors affecting our market
include breadth and depth of a solution, compatibility with existing
applications and operating systems, a substantial customer base and strategic
alliances, core technology, product quality and performance, customer service,
and speed and ease of deployment. We believe our solution currently competes
favorably with respect to these factors. However, our market is relatively new
and evolving rapidly. We may not be able to maintain our competitive position
against current and potential competitors, especially those with significantly
greater financial, marketing, service, support, technical and other resources.

   Some large potential competitors have longer operating histories, larger
customer bases, greater brand recognition, and significantly greater financial,
marketing and other resources than we do and may enter strategic or commercial
relationships with larger, more established and well-financed companies. Some
of our competitors may be able to secure alliances with customers and
affiliates on more favorable terms, devote greater resources to marketing and
promotional campaigns and devote substantially more resources to systems
development than we do. In addition, new technologies and the expansion of
existing technologies may increase competitive pressures on us. We may not be
able to compete successfully against current and future competitors, and
competitive pressures faced by us could harm our business, operating results
and financial condition.

Intellectual Property

   Our success depends in part upon our proprietary technology. We rely on a
combination of trademark and trade secret protection and confidentiality and
nondisclosure agreements to establish and protect our intellectual property
rights. In addition, we seek to avoid disclosure of our trade secrets through a
number of means, including requiring those persons with access to our
proprietary information to execute nondisclosure agreements with us and
restricting access to our source code. We seek to protect our software,
documentation and other written materials under trade secret and copyright
laws, which afford only limited protection. We currently have no patents.

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

   There has been a substantial amount of litigation in the software industry
and the Internet industry regarding intellectual property rights. It is
possible that in the future, third parties may claim that we or our current or
potential future products infringe upon their intellectual property. We

                                       36
<PAGE>

expect that software product developers and providers of Internet-based
software applications will increasingly be subject to infringement claims as
the number of products and competitors in our industry segment grows and the
functionality of products in different industry segments overlaps. Any claims,
with or without merit, could be time consuming, result in costly litigation,
cause product shipment delays or require us to enter into royalty or licensing
agreements. Royalty or licensing agreements, if required, may not be available
on terms acceptable to us or at all, which could seriously harm our business.

   We are a defendant in a lawsuit pending in the U.S. District Court for the
Eastern District of Missouri brought by Bridge Information Systems, or Bridge.
Bridge alleges trademark infringement and related causes of action arising from
our use of 2Bridge. We have responded to the complaint with counterclaims
seeking a declaration of non-liability. Neither party has commenced discovery.
The Court has scheduled a trial date for this matter during 2001. Bridge
recently approached us to discuss an amicable resolution of the dispute. We
have indicated to Bridge that any settlement must allow us to use the name and
mark 2Bridge without any restrictions of field of use. Although we are
continuing our discussions, it is too early to determine whether we will reach
a negotiated settlement. Should we not reach a settlement and if litigation is
decided unfavorably against us, we might be required to pay substantial damages
to Bridge and could be enjoined from using the name and mark 2Bridge unless we
are able to negotiate a license from Bridge.

Employees

   As of March 10, 2000, we employed 124 individuals in the United States. None
of our employees is represented by a labor union or is subject to a collective
bargaining agreement. We believe our relations with our employees are good.

Facilities

   Our executive offices and principal operations are currently located in San
Francisco, California. We curently lease approximately 32,800 square feet of
office space in San Francisco, California under two leases that expire in 2002
and 2005, respectively. We also lease office space in Princeton, New Jersey
under a lease that expires in 2003 and office space in New York, New York under
a lease that expires in 2001. We believe that our existing facilities are
adequate for our current operations.

Classified Board

   Immediately following the offering, our board of directors will consist of
seven directors divided into three classes with each class serving for a term
of three years. At each annual meeting of stockholders, directors will be
elected by the holders of common stock to succeed those directors whose terms
are expiring. In addition, our bylaws provide that the authorized number of
directors may be changed only by resolution of the board of directors. Any
additional directorships resulting from an increase in the number of directors
will be distributed among the three classes so that, as nearly as possible,
each class will consist of one-third of the total number of directors. This
classification of the board of directors may have the effect of delaying or
preventing changes in control of our company.

Board Committees

   The board of directors has a compensation committee and an audit committee.
The compensation committee, currently comprised of Mr. Berlinski and Mr. Perry,
administers our 1997

                                       40
<PAGE>

Stock Option Plan, our 2000 Stock Plan, our 2000 Employee Stock Purchase Plan
and all matters concerning executive compensation and employee agreements. The
audit committee, currently comprised of Mr. Brown, Mr. Perry and Mr. Jabbar,
performs the following functions:

  . monitors our system of internal controls;

  . oversees corporate financial reporting and internal and external audits;

  . outlines to the board of directors the improvements made or to be made in
    internal accounting controls;

  . Nominates our independent auditors; and

  . Provides the board of directors with other information and materials
    necessary to make the board of directors aware of significant financial
    matters.

   Each of the audit committee and compensation committee was established in
March 2000.

Director Compensation

   We do not currently pay cash compensation to directors for serving in that
capacity, nor do we reimburse directors for expenses incurred in attending
board meetings, except for travel expenses of up to $2,000 per board meeting.
We have granted stock options to directors for their services as such under our
1997 Stock Option Plan. In addition, non-employee directors will be entitled to
receive automatic grants of stock options under our 2000 Director Option Plan.
See "Employee Benefits--2000 Director Option Plan."

Compensation Committee Interlocks and Insider Participation

   The compensation committee is currently comprised of Mr. Berlinski and Mr.
Perry. Neither of these committee members has at any time been an officer or
employee of our company and none of our past or present officers or employees
has served as a member of our compensation committee. No interlocking
relationship exists between our board of directors or compensation committee
and the board of directors or compensation committee of any other company, nor
has any such interlocking relationship existed in the past.

Limitation on Liability and Indemnification Matters

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

  . any breach of the director's duty of loyalty to us or our 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, redemptions
    or other distributions; or

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

   Our bylaws require that we indemnify our directors and officers to the
extent permitted by Delaware law. We may, in our discretion, indemnify other
employees and agents to the 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

                                       41
<PAGE>

secure insurance on behalf of any of our officers, directors, employees or
other agents for any liability incurred in that capacity or arising out of that
status. We have obtained directors' and officers' insurance providing
indemnification for some of our directors, officers and employees for certain
liabilities.

   We have also entered into agreements to indemnify our directors and
officers. These agreements indemnify our directors and officers for some
expenses, including attorneys' fees, judgments, fines and settlement amounts
incurred by them in any action or proceeding, including any action by or in the
right of our company, arising out of their services as one of our directors or
officers, any of our subsidiaries or any other company or enterprise to which
the person provides services at our request. We believe that these provisions,
agreements and the insurance we have obtained are necessary to attract and
retain qualified directors and officers.

   The limited liability and indemnification provisions in our certificate of
incorporation and bylaws may discourage stockholders from bringing a lawsuit
against our directors for breach of their fiduciary duty and may reduce the
likelihood of derivative litigation against our directors and officers, even
though a derivative action, if successful, might otherwise benefit us and our
stockholders. Moreover, a stockholder's investment in us may be adversely
affected to the extent we pay the costs of settlement or damage awards against
our directors and officers under these indemnification provisions.

   At present, there is no pending litigation or proceeding involving any of
our directors, officers, employees or agents where indemnification will be
required or permitted. We are not aware of any threatened litigation or
proceeding that might result in a claim for such indemnification.

Executive Compensation

   The following table sets forth information concerning the compensation that
we paid during the fiscal year ended December 31, 1999 to our Chief Executive
Officer and our Chief Financial Officer. The option grant indicated was under

Option Grants in Last Fiscal Year

   The following table sets forth information with respect to stock options
granted to the officers set forth in the Summary Compensation Table during the
year ended December 31, 1999. We have never granted any stock appreciation
rights. All option grants were made under our 1997 Stock Option Plan. The
exercise price per share was equal to the fair market value of the common stock
on the date of grant as determined by the board of directors. The percentage of
total options as set forth in the table below is based on an aggregate of
2,144,902 shares of common stock granted under the 1997 Employee Stock Option
Plan in the year ended December 31, 1999. The potential realizable value is
calculated based on the term of the ten-year option and assumed rates of stock
appreciation of 5% and 10%, compounded annually as set forth in the table
below. These assumed rates comply with the rules of the Securities and Exchange
Commission and do not represent our estimate of future stock price. Actual
gains, if any, on stock option exercises will be dependent on the future
performance of our common stock.

   The following table sets forth information concerning option values for
stock options held by the officers set forth in the Summary Compensation Table.
None of these officers exercised any options in the year ended December 31,

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

Employment Agreements

   We require each of our employees to enter into confidentiality agreements
prohibiting the employee from disclosing any of our confidential or proprietary
information. In addition, the agreements generally provide that upon
termination, the employee will not solicit our employees for a period of 12
months following the end of their employment with our company. At the time of
commencement of employment, our employees also generally sign offer letters
specifying certain basic terms and conditions of employment. Other than as
described above, in general, our employees are not subject to written
employment agreements.

Employee Benefit Plans

 2000 Stock Plan

   Our 2000 Stock Plan was adopted by our board of directors in March 2000, and
we expect our stockholders to approve the plan in April 2000. This stock plan
provides for the grant of incentive stock options to our employees, within the
meaning of Section 422 of the United States tax code, and nonstatutory stock
options and stock purchase rights to our employees, directors and consultants.
As of March 10, 2000, no shares of our common stock have been issued pursuant
to the exercise of options granted under our stock plan and we have no
outstanding options to purchase shares of common stock.

   Our stock plan will automatically terminate in 2010, unless terminated
sooner. In addition, our board of directors has the authority to suspend,
terminate or amend, with shareholder approval to the extent necessary to comply
with applicable laws, the stock plan provided it does not adversely affect any
option previously granted under the plan.

   As of March 10, 2000, a total of 3,000,000 shares of our common stock have
been reserved for issuance pursuant to our 2000 Stock Plan. The plan provides
for an annual increase in authorized shares beginning in 2001 equal to the
lesser of:

  . 5% of the outstanding shares of our common stock on the first day of our
    fiscal year;

  . 2,500,000 shares; or

  . such lesser amount as our board of directors may determine.

In addition, any shares which were reserved but unissued under our 1997 Stock
Option Plan, and any shares that are returned to the 1997 Stock Option Plan as
a result of termination or repurchase of shares, will be available for issuance
under our 2000 Stock Plan.

   Our board of directors or a committee of our board administers the 2000
Stock Plan. The 2000 Stock Plan may be administered by different committees
with respect to different groups of service providers. The administrator has
the power to determine 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 exercisability of the options and the form
of consideration payable upon exercise.

   The administrator determines the exercise price and term of options granted
under our stock plan. With respect to incentive stock options, however, the
exercise price must at least be equal to the fair market value of our common
stock on the date of grant and its term may not exceed ten years.

   No employee, director or consultant may be granted an option to purchase
more than 1,500,000 shares in any fiscal year. In connection with his or her
initial service, an employee, director or consultant may be granted an
additional option to purchase up to 1,500,000 shares of our common stock.

   After termination of one of our employees, directors or consultants, he or
she may exercise his or her option for the period of time stated in the option
agreement. If termination is due to death, the option will generally remain
exercisable for 12 months following such termination. If termination is due to
disability, the option will generally remain exercisable for 12 months
following such termination. In all other cases, the option will generally
remain exercisable for three months. However, an option may never be exercised
later than the expiration of its term. 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 will revert to the plan.

                                       44
<PAGE>

   Unless the administrator determines otherwise, any restricted stock purchase
agreement providing for early exercise of unvested stock options will grant us
a repurchase option that we may exercise upon the voluntary or involuntary
termination of the purchaser's service with us for any reason. The purchase
price for shares we repurchase will generally be the original price paid by the
purchaser. The administrator determines the rate at which our repurchase option
will lapse.

   Our stock plan generally does not allow for the transfer of options or stock
purchase rights and only the optionee may exercise an option or stock purchase
right during his or her lifetime.

   Our stock plan provides that in the event of our merger with or into another
corporation or a sale of substantially all of our assets, the successor
corporation will assume or substitute an equivalent option or right for each
outstanding option or stock purchase right. If the outstanding options or stock
purchase rights are not assumed or substituted, all outstanding options and
stock purchase rights will vest and become exercisable.

 1997 Stock Option Plan

   Our 1997 Stock Option Plan provides for the granting to employees of
incentive stock options within the meaning of Section 422 of the Internal
Revenue Code and for the granting to employees and consultants of nonstatutory
stock options. The terms of the 1997 stock option plan are substantially
similar to those of our 2000 Stock Plan. As of March 10, 2000, 3,156,666 shares
were authorized under the plan, 2,073,876 shares were subject to outstanding
options and 497,476 shares remain available for future grant. Upon the
completion of this offering, the 1997 Stock Option Plan will terminate, no
further option grants will be made under the 1997 Stock Option Plan, and any
shares reserved but not yet issued under the 1997 Stock Option Plan will be
available for future grant under the 2000 Stock Plan.

 2000 Employee Stock Purchase Plan

   Our board of directors adopted the 2000 Employee Stock Purchase Plan in
March 2000 and our stockholders are expected to approve the plan in April 2000.
A total of 750,000 shares of common stock have been reserved for issuance under
our 2000 Employee Stock Purchase Plan. The plan provides for annual increases
on the first day of each fiscal year beginning 2001 equal to the lesser of:

  . 750,000 shares;

  . 2% of our outstanding shares as of such date; or

  . another amount determined by the board of directors.

   The 2000 Employee Stock Purchase Plan, which is intended to qualify under
Section 423 of the Internal Revenue Code, contains 24-month offering periods.
The offering periods generally start on the first trading day on or after May 1
and November 1 of each year, except for the first such offering period, which
will commence 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, 2002. Each
offering period will have four purchase periods of approximately six-months
duration.

   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, the following employees may not be
granted options to purchase stock under the purchase plan:

  . any employee who immediately after the grant would own stock possessing
    5% or more of the total combined voting power or value of all classes of
    our capital stock; or

  . any employee 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.

                                       45
<PAGE>

   Participants may purchase common stock through payroll deductions of up to
15% of the participant's compensation. The maximum number of shares a
participant may purchase during a six month offering 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 purchase plan is 85% of the lower of the fair market value
of the common stock at the beginning of the offering period and the fair market
value of the common stock at end of the purchase period.

   Our purchase plan provides that in the event we merge with or into another
company, or we sell substantially all of our assets, each outstanding option
may be assumed or substituted by the successor company. If the successor
company refuses to assume or substitute the options, the offering period then
in progress will be shortened and a new exercise date will be set, which will
occur before the proposed merger or sale.

   The 2000 Employee Stock Purchase Plan will become effective on the effective
date of this offering and will terminate ten years thereafter, unless sooner
terminated by the board of directors. The board has the authority to amend or
terminate the purchase plan, except that no such action may adversely affect
any outstanding rights to purchase stock.

 2000 Director Option Plan

   Our board of directors adopted the 2000 Director Option Plan in March 2000
and we expect our stockholders to approve it in April 2000. The director plan
provides for the periodic grant of nonstatutory stock options to our non-
employee directors.

   As of March 10, 2000, a total of 400,000 shares were reserved for issuance
under our director option plan.

   All grants of options to our non-employee directors under the director
option plan are automatic and non-discretionary. We will grant an option to
purchase 25,000 shares to each non-employee director who joins the board after
our initial public offering when such person first becomes a non-employee
director (except for those directors who became non-employee directors by
ceasing to be employee directors). All non-employee directors who have been
directors for at least 6 months receive an option to purchase 10,000 shares
each year on the date of our annual stockholders meeting.

   All options granted under our director option plan have a term of ten years
and an exercise price equal to fair market value on the date of grant. The
option granted initially to non-employee directors becomes exercisable over two
years with 1/24th of the total shares exercisable per month. The option granted
to non-employee directors on the date of our annual stockholders meeting
becomes exercisable as to 100% of the shares subject to the option on the date
of grant.

   After termination as a non-employee director, an optionee must exercise an
option at the time set forth in his or her option agreement. If termination is
due to disability, the option will generally remain exercisable for six months.
If termination is due to death, the estate will be able to exercise the option
for 12 months. In all other cases, the option will remain exercisable for a
period of three months.

   A non-employee director may not transfer options granted under our 2000
Director Option Plan other than by will or the laws of descent and
distribution. Only the non-employee director may exercise the option during his
or her lifetime.

                                       46
<PAGE>

   In the event of our merger with or into another corporation or a sale of
substantially all of our assets, the successor corporation will assume or
substitute an equivalent option for each outstanding option. If such assumption
or substitution occurs, the options will continue to be exercisable according
to the same terms as before the merger or sale of assets. Following such
assumption or substitution, if a non-employee director is terminated other than
by voluntary resignation, the option will become fully exercisable. If the
outstanding options are not assumed or substituted for, our board of directors
will notify each non-employee director that he or she has the right to exercise
the option as to all shares subject to the option for a period of 30 days
following the date of the notice. The option will terminate upon the expiration
of the 30-day period.

   Unless terminated sooner, our director option plan will automatically
terminate in 2010. Our board of directors has the authority to amend, alter,
suspend, or discontinue the director option plan, but no such action may
adversely affect any grant made under the director option plan.

 401(k) Savings Plan

   We sponsor a 401(k) savings in which eligible employees may participate. The
401(k) savings plan is intended to qualify under Sections 401(a) and 401(k) of
the Internal Revenue Code of 1986, as amended. Contributions to the 401(k)
savings plan and income earned on such contributions are not taxable to
employees until withdrawn from the 401(k) savings plan. Subject to restrictions
imposed by the Internal Revenue Code on highly compensated employees, employees
may generally defer up to 15% of their pre-tax earnings up to the statutorily
prescribed annual limit, which is $10,500 for the 2000 calendar year, and to
have the amount of such reduction contributed to the 401(k) savings plan. The
401(k) savings plan permits, but does not require, additional matching
contributions to the 401(k) savings plan. To date, we have not made any
matching contributions to the 401(k) savings plan. The 401(k) savings plan may
be amended or terminated by us at anytime, and in our sole discretion.

Founder Stock Purchase Agreement; Restricted Stock Purchase Agreement

   Mr. Mansoor Zakaria, our Chief Executive Officer, was issued 8,000,000
shares pursuant to a Founder Stock Purchase Agreement. Under this agreement, we
have a right of first refusal with respect to his shares, which will expire
upon our initial public offering. In January 1997, we also issued to Ronald
Lachman, a former director of our company, 500,000 shares of our common stock.
Pursuant to a Restricted Stock Purchase Agreement, we have a right of first
refusal with respect to his shares, which will expire upon our initial public
offering.

Other Transactions

   On June 1, 1998, we authorized a full recourse loan to Mansoor Zakaria for a
principal amount not to exceed $1.2 million. All principal and interest under
the loan is payable upon the earlier of July 1, 2003 or the termination of Mr.
Zakaria's full-time employment with us. As of December 31, 1999, approximately
$400,000 of principal and accrued interest was outstanding.

   On March 8, 2000, we authorized the sale of 266,666 shares of common stock
to Milton Berlinski, a director of our company, at a purchase price of $5.25
per share and 33,333 shares of common stock to David Braunschvig, a director of
our company, at a purchase price of $5.25 per share. Mr. Berlinski and Mr.
Braunschvig were granted piggy-back registration rights with respect to such
common stock.

   We have entered into indemnification agreements with each of our executive
officers and directors.

   We have granted options to certain of our executive officers and directors.
Please see "Option Grants in Last Fiscal Year," and "Founder Stock Purchase
Agreement; Restricted Stock Purchase Agreement."

   Holders of preferred stock are entitled to certain registration rights with
respect to the common stock issued or issuable upon conversion of the preferred
stock. Please see "Description of Capital Stock--Registration Rights."

   We believe that all related-party transactions described above were on terms
no less favorable than could have been otherwise obtained from unrelated third
parties.

                             PRINCIPAL STOCKHOLDERS

   The following table sets forth certain information with respect to
beneficial ownership of our common stock, as of March 10, 2000, and as adjusted
to reflect the sale of common stock offered by us in this offering, for:

  . each person who we know beneficially owns more than 5% of the common
    stock;

  . each of our directors;

  . each executive officer named in the Summary Compensation Table; and

  . all of our directors and officers as a group.

   Unless otherwise indicated, the principal address of each of the
stockholders below is c/o 2Bridge, Inc., 221 Main St., Suite 800, San
Francisco, California 94105. Beneficial ownership is determined in accordance
with the rules of the Securities and Exchange Commission and includes voting or
investment power with respect to the securities. Except as indicated by
footnote, and subject to applicable community property laws, each person
identified in the table possesses sole voting and investment power with respect
to all shares of common stock shown held by them.

   Shares underlying options that are deemed beneficially owned and exercisable
within 60 days of March 10, 2000 are listed in this table separately in the
column labeled "Shares Subject to Options." These shares are included in the
number of shares listed in the column labeled "Total Number." The numbers shown
in the table assume no exercise by the underwriters of their over-allotment
option.

   The number of shares of common stock outstanding used in calculating the
percentage for each listed person includes shares of common stock underlying
options or warrants held by such person that are exercisable within 60 days of
March 10, 2000, but excludes shares of common stock underlying options or
warrants held by any other person. Percentage of beneficial ownership is based
on shares of common stock outstanding as of March 10, 2000, after giving effect
to the conversion of all outstanding shares of preferred stock upon the closing
of this offering.

                          DESCRIPTION OF CAPITAL STOCK

   Upon the completion of this offering, our authorized capital stock will
consist of 100,000,000 shares of common stock, $0.0001 par value, and 5,000,000
shares of preferred stock, $0.0001 par value.

   The following summary of the rights of the common stock and preferred stock
does not purport to be complete and is subject to, and qualified in its
entirety by, the provisions of our amended and restated certificate of
incorporation and bylaws which are included as exhibits to the registration
statement of which this prospectus is a part and by the provisions of Delaware
law.

Common Stock

   After giving effect to the two-for-three reverse stock split of all
outstanding common stock and preferred stock and the conversion of all
previously outstanding preferred stock into shares of common stock, as of March
10, 2000, there were 23,751,496 shares of common stock outstanding held of
record by approximately 126 stockholders. There will be     shares of common
stock outstanding, assuming no exercise of the underwriters' over-allotment
option and no exercise of certain outstanding options or warrants, after giving
effect to the sale of common stock in the offering.

   Subject to preferences that may be applicable to any preferred stock
outstanding at the time, the holders of outstanding shares of common stock are
entitled to the following rights:

  . to receive dividends out of assets legally available therefor at such
    times and in such amounts as the board of directors from time to time may
    determine;

  . one vote for each share held on all matters submitted to a vote of
    stockholders; and

  . upon our liquidation, dissolution or winding-up, to share ratably in all
    assets remaining after payment of liabilities and the liquidation of any
    preferred stock.

   Cumulative voting for the election of directors is not authorized by our
certificate of incorporation, which means that the holders of a majority of the
shares voted can elect all of the directors then standing for election. The
common stock is not entitled to preemptive rights, conversion rights or other
subscription rights. There are no redemption or sinking fund provisions
applicable to the common stock. Each outstanding share of common stock is, and
all shares of common stock to be outstanding upon completion of this offering
will be, upon payment therefor, duly and validly issued, fully paid and
nonassessible. 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 any shares of any series of preferred stock which we may designate
in the future.

Preferred Stock

   Upon completion of this offering, our board of directors has the authority,
without further action by the stockholders, to issue up to 5,000,000 shares of
preferred stock in one or more series and to fix the designations, powers,
preferences, privileges, which may be greater than the rights of the common
stock. The board, without stockholder approval, can issue preferred stock with
voting, conversion or other rights that could adversely affect the voting power
and other rights of the holders of common stock. Preferred stock could thus be
issued quickly with terms calculated to delay or prevent a change in control of
our company or make removal of management more difficult. Additionally, the
issuance of preferred stock may have the effect of decreasing the market price
of the common stock. At present, there are no shares of preferred stock
outstanding, and we have no plans to issue any of the preferred stock.

                                       52
<PAGE>

Registration Rights

   Upon completion of the offering and assuming the exercise of all of our
currently outstanding warrants, the holders of an aggregate of approximately
24,372,421 shares of common stock will be entitled to certain rights with
respect to the registration of such shares under the Securities Act of 1933.
Under the terms of the amended and restated investors' rights agreement, if we
propose to register any of its securities under the Securities Act of 1933,
either for our own account or for the account of other security holders, these
holders are entitled to notice of such registration and are entitled to include
shares of common stock in the registration. The rights are subject to
conditions and limitations, among them the right of the underwriters of an
offering subject to the registration to limit the number of shares included in
such registration. A limited number of the holders of these rights may also
require us to file a registration statement under the Securities Act of 1933
with respect to their shares of common stock and we are required to use our
best efforts to effect such registration, subject to conditions and
limitations. Furthermore, stockholders with registration rights may require us
to file additional registration statements on Form S-3, subject to conditions
and limitations.

Delaware Anti-Takeover Law and Certain Charter and Bylaws Provisions

   Delaware Anti-Takeover Statute. We are subject to Section 203 of the
Delaware General Corporation Law. In general, these provisions prohibit a
Delaware corporation from engaging in any business combination with any
interested stockholder for a period of three years following the date that the
stockholder became an interested stockholder, unless the transaction in which
the person became an interested stockholder is approved in a manner presented
in Section 203 of the Delaware General Corporation Law.

   Generally, a "business combination" is defined to include mergers, asset or
stock sales and other transactions resulting in financial benefit to a
stockholder. In general, an "interested stockholder" is a person who, together
with affiliates and associates, owns, or within three years, did own, 15% or
more of a corporation's outstanding voting stock.

   Certificate of Incorporation and Bylaws. Our certificate of incorporation
and bylaws include provisions that:

  . allow the board of directors to issue, without further action by the
    stockholders, up to 5,000,000 shares of undesignated preferred stock;

  . require that any action to be taken by our stockholders be effected at a
    duly called annual or special meeting and not by written consent;

  . divide the board of directors into three classes, with each class serving
    for a term of three years;

  . prohibit cumulative voting in the election of directors;

  . require that special meetings of our stockholders be called only by the
    board of directors, the chairman of the board, the chief executive
    officer and the president;

  . establish an advance notice procedure for stockholder proposals to be
    brought before an annual meeting of our stockholders, including proposed
    nominations of persons for election to the board of directors; and

  . require that certain amendments to the certificate of incorporation and
    the bylaws require the approval of the holders of at least 66 2/3% of the
    voting power of all outstanding stock.

   These provisions are intended to enhance the likelihood of continuity and
stability in the composition of the board and in the policies formulated by the
board and to discourage certain types

                                       53
<PAGE>

of transactions that may involve an actual or threatened change of control of
our company. These provisions are designed to reduce our vulnerability to an
unsolicited proposal for a takeover that does not contemplate the acquisition
of all of our outstanding shares or an unsolicited proposal for the
restructuring or sale of all or part of our company. These provisions,
however, could discourage potential acquisition proposals and could
complicate, delay or prevent a change in control of our company. They may also
have the effect of preventing changes in our management. We believe that the
benefits of increased protection of our potential ability to negotiate with
the proponent of an unfriendly or unsolicited proposal to acquire or
restructure us outweighs the disadvantages of discouraging these proposals,
including proposals that are priced above the then current market value of our
common stock, because, among other things, negotiation of these proposals
could result in an improvement of their terms.

Transfer Agent and Registrar

   The transfer agent and registrar for common stock is ChaseMellon
Shareholder Services, L.L.C.

                                      54
<PAGE>

                        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 the 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 the offering, we will have outstanding an aggregate of
    shares of common stock, assuming no exercise of the underwriters' over-
allotment option and no exercise of outstanding options or outstanding
warrants. Of these outstanding shares,      shares sold in the offering will be
freely tradable without restriction or further registration under the
Securities Act of 1933, unless purchased by our "affiliates" as that term is
defined in Rule 144 under the Securities Act of 1933. The remaining 23,751,496
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 of 1933. 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 of 1933, 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 the common stock.

   All officers, directors and certain other holders of 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 Deutsche Bank
Securities 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 available beginning 181 days after the
effective date of the offering, subject in some cases to certain volume
limitations.

   Of the remaining restricted shares:

  . no shares are subject to our repurchase option in the event of
    termination of employment; and

  . 1,029,200 shares will not be eligible for sale pursuant to Rule 144 until
    at least March 10, 2001 with respect to 743,200 shares and until at least
    March 8, 2001 with respect to the remaining 286,000 shares.

   On November  , 2000, approximately 431,090 shares subject to vested options
will be available for sale subject to compliance with Rule 701 and upon the
expiration of agreements not to sell such shares entered into between the
underwriters and such stockholders. Any shares subject to lock-up agreements
may be released at any time without notice by the underwriters.

   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     shares immediately after the offering; or

  . 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.

                                       55
<PAGE>

   Sales under Rule 144 are also subject to certain 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 certain 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 certain compensatory benefit
plans and contracts commencing 90 days after the issuer becomes subject to the
reporting requirements of the Securities Exchange Act of 1934, in reliance upon
Rule 144 but without compliance with certain restrictions, including the
holding period requirements. In addition, the Securities and Exchange
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 Securities Exchange Act of 1934, 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 have agreed not to sell or otherwise dispose of any shares of common
stock or any securities convertible into or exercisable or exchangeable for

   SG Cowen Securities Corporation....................................
   Thomas Weisel Partners LLC.........................................
                                                                          ---
     Total Underwriters...............................................
                                                                          ===
</TABLE>

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

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

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

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

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

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

   Each of our officers and directors and substantially all of our stockholders
and holders of options and warrants to purchase our stock, has agreed not to
offer, sell, contract to sell or otherwise dispose of, or enter into any
transaction that is designed to, or could be expected to, result in the
disposition of any portion of our common stock held by these persons prior to
this offering or common stock issuable upon exercise of options or warrants
held by these persons for a period of 180 days after the effective date of the
registration statement of which this prospectus is a part without the prior
written consent of Deutsche Bank Securities Inc. This consent may be given at
any time without public notice. We have entered into a similar agreement with
the representatives of the underwriters.

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

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

   At our request, the underwriters have reserved for sale, at the initial
public offering price, up to     shares for friends and family members of our
executive officers and other persons that are affiliated with companies with
whom we have a business relationship, such as executives of companies that
market, sell or otherwise promote our products. None of these shares will be
subject to lock-up agreements.

   The number of shares of our common stock available for sale to the general
public will be reduced to the extent these reserved shares are purchased. Any
reserved shares that are not purchased by these persons will be offered by the
underwriters to the general public on the same basis as the other shares in
this offering.

   Thomas Weisel Partners LLC, one of the representatives of the underwriters,
was organized and registered as a broker-dealer in December 1998. Since
December 1998, Thomas Weisel Partners has been named as a lead or co-manager on
138 filed public offerings of equity securities, of which 102 have been
completed, and has acted as a syndicate member in an additional 75 public
offerings of equity securities. Thomas Weisel Partners does not have any
material relationship with us or any of our officers, directors or other
controlling persons, except with respect to its contractual relationship with
us pursuant to the underwriting agreement entered into in connection with this
offering and the share ownership of individuals associated with Thomas Weisel
Partners stated below.

   In March 2000, we sold 743,200 shares of our Series D preferred stock in a
private placement at a price of $9.65 per share. Each of the shares of Series D
preferred stock is convertible at the option of the holder into one shares of
our common stock. In this private placement, individuals associated with
Deutsche Bank Securities Inc. purchased 40,402 shares of Series D preferred
stock for an aggregate purchase price of approximately $315,000 and individuals
associated with Thomas Weisel Partners LLC purchased 11,654 shares of Series D
preferred stock on the same terms as the other investors in the private
placement. The aggregate number of shares of Series D preferred Stock purchased
by Deutsche Bank Securities Inc. and Thomas Weisel Partners LLC was 52,056
shares. Upon conversion of these shares into common stock, based on an assumed
initial public offering price of $   , the value of these shares is $   . The
difference between the amount that     and     originally paid for the Series D
preferred stock and the value of the Series D preferred stock based on the
assumed initial public offering price of $    equals $   .

Pricing of this Offering

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

  . prevailing market conditions;

  . our results of operations in recent periods;

  . the present stage of our development;

  . the market capitalizations and stages of development of other companies
    that we and the representatives of the underwriters believe to be
    comparable to our business; and

  . estimates of our business potential.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Stockholders
2Bridge, Inc.

   We have audited the accompanying balance sheets of 2Bridge, Inc. as of
December 31, 1998 and 1999, and the related statements of operations,
redeemable convertible preferred stock and stockholders' equity (deficit), and
cash flows for each of the three years in the period ended December 31, 1999.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.

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

   In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of 2Bridge, Inc. at December
31, 1998 and 1999, and the results of its operations and its cash flows for
each of the three years in the period ended December 31, 1999, in conformity
with accounting principles generally accepted in the United States.

                         NOTES TO FINANCIAL STATEMENTS
                     Years Ended December 31, 1998 and 1999

1. The Company and Summary of Significant Accounting Policies

The Company

   2Bridge (the "Company") provides comprehensive Internet-based solutions to
create many-to-many communication, commerce and collaboration eHubs for
businesses. An eHub is an Internet-based workspace where customers, partners,
suppliers and employees can simultaneously interact, access real-time business
information, integrate business processes and conduct eCommerce transactions.
The Company's solutions were released during the fourth quarter of 1998. The
Company conducts business primarily in the United States and operates in one
business segment which is the development of Internet-based eHub solutions for
businesses. One customer accounted for 41% and 55% of total revenues during the
years ended December 31, 1998 and 1999, respectively. Another customer
accounted for 30% and 13% of total revenues during the years ended December 31,
1998 and 1999, respectively. One customer accounted for 22% of total revenues
during the year ended December 31, 1998 and one customer accounted for 10% of
total revenues during the year ended December 31, 1999.

Use of Estimates

   The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results may differ from those
estimates.

Cash and Cash Equivalents

   Cash and cash equivalents consist of highly liquid investments with minimal
interest rate risks that have maturities of three months or less at date of
purchase and are stated at cost, which approximates fair value. The Company
maintains its cash in depository accounts with two domestic financial
institutions.

Concentrations of Credit Risk and Credit Evaluations

   Financial instruments, which subject the Company to concentrations of credit
risk, consist primarily of trade accounts receivable.

   A limited number of customers historically have accounted for a substantial
portion of the Company's revenues. The Company performs ongoing credit
evaluations of its customers and generally does not require collateral. Sales
of the Company's products and services will vary as a result of fluctuations in
market demand for such products and technology. Further, the markets in which
the Company competes are characterized by rapid technological change and
increased competition.

                                 2BRIDGE, INC.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   One customer accounted for $144,000 of the total accounts receivable balance
as of December 31, 1998 and $1,700,000 of the total accounts receivable balance
as of December 31, 1999.

Property and Equipment

   Property and equipment are stated at cost and are depreciated using the
straight-line method over the estimated useful lives of the related assets,
generally three to five years. Assets under capital leases are included in
depreciable assets and amortized using the straight-line method over the
shorter of the estimated useful life or lease term, which is generally three
years. Leasehold improvements are amortized using the straight-line method over
the shorter of the estimated useful life or the life of the lease.

Revenue Recognition

   Effective January 1, 1998, the Company adopted Statement of Position 97-2,
"Software Revenue Recognition" ("SOP 97-2"), as amended by Statement of
Position 98-4 ("SOP 98-4") which was issued by the American Institute of
Certified Public Accountants ("AICPA"). The Company believes its current
revenue recognition policies and practices are consistent with SOP 97-2 and SOP
98-4. Additionally, the AICPA issued SOP 98-9 in December 1998, which provides
certain amendments to SOP 97-2, and is effective for transactions, entered into
beginning January 1, 2000. Full implementation guidelines for this standard
have not yet been issued. Once available, such implementation guidelines could
lead to unanticipated changes in the Company's current revenue recognition
policies, which changes could affect the timing of the Company's future
revenues and results of operations.

   Prior to the fourth quarter of 1999, the Company sold its software as stand-
alone products and derived revenues from the licenses, maintenance and support
from the software application. The Company recognized revenues from these
agreements upon delivery and acceptance of the software if there was persuasive
evidence of an arrangement, collection was probable, the fee was fixed or
determinable, and there was sufficient vendor-specific objective evidence to
support allocating the total fee to all elements of multiple-element
arrangements. Software maintenance revenues are recognized ratably over the
term of the support contract, which is generally one year. Other service
revenue is recognized as services are performed. Payments received prior to
delivering services are recorded as deferred revenue. Through December 31,
1999, deferred revenue has not been significant.

   During the fourth quarter of 1999, the Company began offering its 2Share
solution, although software-based, as a managed solution, which may include
custom design and related services that are designed to deliver dial-tone-like
access, reliability and functionality. As a result, the Company discontinued
using a license sales model and began selling its solutions through recurring
fee agreements. Recurring fees are recognized over the term of the agreement.

Software Development Costs

   The Company accounts for software development costs in accordance with
Statement of Financial Accounting Standards No. 86, "Accounting for the Cost of
Computer Software to be Sold, Leased, or Otherwise Marketed," under which
certain software development costs incurred subsequent to the establishment of
technological feasibility are capitalized and amortized over the estimated
useful lives of the related products. Technological feasibility is established
upon completion of a working model. As of December 31, 1999, such capitalizable
software development

                                      F-8

                  NOTES TO FINANCIAL STATEMENTS--(Continued)

costs have been insignificant and all software development costs have been
charged to product development expenses in the accompanying statements of
operations.

Income Taxes

   Income taxes are accounted for in accordance with Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes," which requires
the use of the liability method in accounting for income taxes. Under this
method, deferred tax assets and liabilities are measured using enacted tax
rates and laws that will be in effect when the differences are expected to
reverse.

Advertising Costs

   The Company expenses the costs of advertising as incurred. Advertising
expense was $3,647,000 for the year ending December 31, 1999. No advertising
expenses were incurred during the years ended December 31, 1997 and 1998.

Accounting For Stock-Based Compensation

   The Company accounts for employee stock options in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB 25"), and has adopted the "disclosure only" alternative
described in Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation" ("SFAS 123").

Reclassifications

   Certain prior years amounts have been reclassified to conform to the
current year presentation.

2. Net Loss Per Share

   Basic and diluted net loss per share information for all periods is
presented under the requirement of SFAS No. 128, "Earnings per Share" ("SFAS
128"). Basic earnings per share has been computed using the weighted-average
number of common shares outstanding during the period and excludes any
dilutive effects of stock options, warrants, and convertible securities.
Potentially dilutive securities also have been excluded from the computation
of diluted net loss per share, as their inclusion would be antidilutive.

4. Financings

Line of Credit

   As of December 31, 1999, the Company has a $5,050,000 line of credit with a
financing company, which was used to finance equipment purchases and operating
activities during the year ending December 31, 1999. Borrowings under the line
of credit bear interest at prime rate plus 3% (11.5% at December 31, 1999) and
are secured by substantially all of the Company's assets. At December 31, 1999,
the Company had outstanding borrowings totaling $5,050,000 and $73,000 in
accrued interest, which are due on July 31, 2000. Warrants were issued in
connection with this financing. See Note 7.

Leases

   As of December 31, 1999, the Company had obtained credit lines from a number
of lease finance companies for the purpose of acquiring computer and office
equipment and leasehold improvements. In aggregate, the Company has entered
into lease finance agreements which allow for borrowings of up to $1,100,000,
bear interest between 6% and 11.5% per annum, and have terms ranging from 24 to
36 months. As of December 31, 1998 and 1999, the Company had outstanding
borrowings of $436,000 and $852,000, respectively, under the equipment lease
arrangements. Amounts outstanding under the lease arrangements are classified
as capital lease obligations in the balance sheet and are secured by the
related equipment. Warrants were issued in connection with this financing. See
Note 7.

Notes Payable

   In September 1998, the Company restructured certain loan and security
agreements. Under the restructured agreement, the Company borrowed $2,500,000,
which was repaid in full with accrued interest in November 1999.

5. Income Taxes

   Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
purposes and the amounts used for income tax purposes. Significant components
of the Company's deferred tax assets are as follows (in thousands):

</TABLE>

   Realization of deferred tax assets is dependent upon future earnings, if
any, the timing and amount of which are uncertain. Accordingly, the net
deferred tax assets have been fully offset by a valuation allowance. The
valuation allowance increased by $2,970,000 and $5,812,000 during 1998 and
1999, respectively.

   As of December 31, 1999, the Company had net operating loss carryforwards
for federal income tax purposes of approximately $25,000,000, which expire in
the years 2010 through 2019. The Company also had net operating loss
carryforwards for state income tax purposes of approximately $15,000,000

   Utilization of the Company's net operating loss carryforwards may be subject
to substantial annual limitation due to the ownership change limitations
provided by the Internal Revenue Code and similar state provisions. Such an
annual limitation could result in the expiration of the net operating loss
carryforwards before utilization.

</TABLE>

 Dividends

   The holders of shares of the Series A, Series B, and Series C preferred
stock (collectively, "preferred stock") are entitled to receive non-cumulative
dividends, when and as declared by the Board of Directors, but only out of
funds that are legally available, at the rate of 5% of the original purchase
price per annum on each outstanding share of Preferred Stock (as adjusted for
any stock dividends, combinations or splits with respect to such shares). While
preferred stock remains outstanding, no dividend will be paid or declared, nor
will any other distribution be made on any common stock until all dividends on
the preferred stock have been paid.

 Conversion

   Each share of preferred stock, at the option of the holder, is convertible
into the number of fully paid and nonassessable shares of common stock at the
conversion rate. The conversion rate per share of preferred stock is 1:1. The
conversion rate is subject to adjustment as defined in the Series A, Series B,
and Series C preferred stock agreements. The number of shares of common stock
into which a share of a series of preferred stock is convertible is referred to
as the conversion rate of such series.

   Each share of preferred stock will automatically be converted into shares of
common stock, based on the then-effective conversion rate, at any time upon the
affirmative vote of a majority of the outstanding shares of the preferred
series, or immediately upon the closing of a firmly 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 for the
account of the Company in which (i) the per share price is at least $7.50 (as
adjusted for stock splits, recapitalizations and the like), and (ii) the gross
cash proceeds to the Company (before underwriting discounts, commissions and
fees) are at least $20,000,000.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)

 Redemption

   Upon a request, the holders of not less than two-thirds of the outstanding
shares of Series A, Series B, or Series C preferred stock, as applicable, may
require the Company to redeem for cash up to all of the Series A, Series B, or
Series C preferred stock outstanding on or after May 18, 2006 (the "Redemption
Date"). Upon the event of this election, the Company will redeem 33.3% of the
number of shares of preferred stock outstanding 60 days after the Redemption
Date, 50% of the number of shares of preferred stock outstanding as of the
first anniversary of the Redemption Date, and the balance of preferred stock
outstanding as of the second anniversary of the Redemption Date. The Company
will effect such redemptions on the applicable Redemption Date by paying in
cash in exchange for the shares of preferred stock to be redeemed a sum equal
to the original purchase price for each share of preferred stock (as adjusted
for any stock dividends, combinations or splits), plus all declared but unpaid
dividends on such shares.

   If the Company 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 Company), then the Company will
redeem such shares pro rata to the extent possible and will redeem the
remaining shares to be redeemed as soon as sufficient funds are legally
available.

 Liquidation

   In the event of any liquidation, dissolution or winding up of the Company,
whether voluntary or involuntary, the holders of preferred stock are entitled
to receive, prior and in preference to any distribution of any of the assets of
the Company to the holders of common stock by reason of their ownership, an
amount per share equal to the sum of the original purchase price for each share
of preferred stock plus any declared but unpaid dividends with respect to such
shares. After payment of the full liquidation preference of the preferred
shareholders, any remaining assets of the Company legally available are to be
distributed ratably to the holders of the common stock and preferred stock on
an as-if-converted to common stock basis until such time as the holders of
preferred stock have received a total liquidation amount of one and one-half
times the original purchase price. The remaining assets of the Company legally
available for distribution, if any, are to be distributed ratably to the
holders of common stock. The holders of Series C preferred stock are entitled
to receive any distribution of any of the assets or surplus funds in preference
to holders of Series A and B preferred stock and common stock.

   If, upon the occurrence of a liquidation event, the assets and funds
distributed among the holders of the preferred stock are insufficient to permit
the payment to such holders of the full preferential amount, then the entire
assets and funds of the Company legally available for distribution are to be
distributed among the holders of the preferred stock, in proportion to the
preferential amount each such holder is otherwise entitled to receive.

 Voting

   The holder of each share of preferred stock is 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, and has voting rights and powers equal to
the voting rights and powers of the common stock.

7. Stockholders' Equity

Common Stock

   In January 1997, the Company issued 500,000 shares of common stock to a
consultant in satisfaction of all obligations and liabilities owed to the
consultant by the Company. The obligation and liabilities related to services
provided by the consultant prior to January 1, 1997. The Company recognized
$65,000 of expense based on the estimated fair value of the shares.

Warrants

   In January 1997, in connection with obtaining the issuance of Series A
redeemable preferred stock, the Company issued warrants to investors to
purchase up to 333,333 shares of common stock at an exercise price of $1.88 per
share. These warrants are outstanding as of December 31, 1999 and are
exercisable through January 17, 2002. In November 1997, in connection with an
equipment lease arrangement, the Company issued a warrant to the lessor to
purchase up to 19,117 shares of common stock at an exercise price of $1.31 per
share. The warrants are outstanding at December 31, 1999 and are exercisable
through November 2004. The Company deemed the fair value of the warrants to be
immaterial using the Black Scholes method.

   In connection with obtaining financing in March 1998, the Company issued
warrants to a lease finance company to purchase up to 68,058 shares of the
Company's Series B preferred stock at an exercise price of $2.11 per share.
These warrants are outstanding as of December 31, 1999 and are exercisable
through March 11, 2008. The Company deemed the fair value of the warrants to be
$115,000 and has amortized $101,000 to interest expense as of December 31,
1999. These warrants were valued under the Black Scholes method with the
following assumptions: volatility - .7, dividend yield - 0%, expected life - 7
years, risk-free interest rate - 6.2%.

   In July 1999, in connection with obtaining financing, the Company issued two
warrants to financing institutions to purchase up to 39,072 and 37,509 shares,
respectively, of the Company's Series C preferred stock at an exercise price of
$3.20 per share. These warrants are outstanding as of December 31, 1999 and are
exercisable through July 2009 and May 2006, respectively. The Company
determined the fair value of the warrants to be $101,000 and $86,000, and has
amortized $63,000 and $86,000, respectively, to interest expense as of December
31, 1999. These warrants were valued under the Black Scholes method with the
following assumptions: volatility - .7, dividend yield - 0%, expected life - 7
and 10 years, risk-free interest rate - 5.4%.

   In July and October 1999, in connection with an equipment shares lease
arrangement, the Company issued warrants to the lessor to purchase up to 3,907
and 7,815, respectively, of the Company's Series C preferred stock at an
exercise price of $3.20 per share. These warrants are outstanding as of
December 31, 1999 and are exercisable through July 2002 and October 2009,
respectively. The Company deemed the fair value of the warrants to be
immaterial using the Black Scholes method.

   In connection with the line of credit (Note 4), the Company issued warrants
to purchase shares in the Company's next round of preferred stock financing
(the "Next Round") at 70% of the estimated sales price per share. The number of
shares subject to the warrant will be derived by dividing $757,500 by the
exercise price. If the next round of financing does not occur by July 31, 2000,
the warrants will be exercisable into 236,718 shares of the Company's Series C
preferred stock at an exercise price of $3.20 per share. See Note 13. These
warrants are outstanding as of December 31,

1999 and are exercisable through March 11, 2008. The warrants will
automatically expire upon an initial public offering of the Company's common
stock if not exercised. The Company determined the fair value of the warrants
to be $540,000 which was recorded in stockholders' equity, of which $95,000 has
been amortized to interest expense as of December 31, 1999. These warrants were
valued under the Black Scholes method with the following assumptions:
volatility -.7, dividend yield -0%, expected life -5.4%.

Stock Options

   Under the Company's 1997 Stock Option Plan (the "Plan"), 3,156,666 shares of
common stock are reserved for the issuance of incentive stock options (ISO's)
and non-qualified stock options (NSO's) to certain directors, employees and
consultants of the Company. The ISO's may be granted at a price per share not
less than the fair market value at the date of grant. The NSO's may be granted
at a price per share not less than 85% of the fair market value at the date of
grant. If at any time the Company grants an option and the optionee directly or
by attribution owns stock possessing more than 10% of the total combined voting
power of all classes of stock of the Company, the option price shall be at
least 110% of the fair value at that date. The options generally vest over four
years and expire ten years after the date of grant.

Deferred Compensation

   The Company recorded deferred stock compensation of $115,000, $16,000, and
$8,533,000 during the years ended December 31, 1997, 1998, and 1999,
respectively, representing the difference between the exercise price and the
deemed fair value of the Company's common stock on the grant date for certain
of the Company's stock options granted to employees. In the absence of a public
market for the Company's common stock, the deemed fair value was based on the
price per share of recent preferred stock financings, less a discount to give
effect to the superior rights of the preferred stock. These amounts are being
amortized by charges to operations over the vesting periods of the individual
stock options using a graded vesting method. Such amortization amounted to
approximately $40,000, $54,000, and $1,282,000 for the years ended December 31,
1997, 1998, and 1999, respectively.

Pro Forma Disclosures on the Effect of Stock-Based Compensation

   Pro forma information regarding results of operations and net loss per share
is required by SFAS 123, which also requires that the information be determined
as if the Company had accounted for its employee stock options under the fair
value method of SFAS 123. The fair value for these options was estimated at the
date of grant using the minimum value method with the following weighted
average assumptions:

   Had compensation cost for the Company's stock-based compensation plans been
determined using the fair value at the grant dates for awards under those plans
calculated using the minimum value method of SFAS 123, the Company's basic and
diluted net loss and pro forma basic and diluted net loss per share would have
been impacted as follows (in thousands):

9. Commitments and Contingencies

   The Company leases office space and certain equipment under non-cancelable
operating leases. Capital lease obligations represent the present value of
future rental payments under capital lease agreements for equipment. Future
minimum lease payments under capital and operating leases, having initial terms
in excess of one year, are as follows at December 31, 1999 (in thousands):

   For the years ended December 31, 1997, 1998 and 1999, rent expense totaled
$248,000, $474,000 and $960,000, respectively.

   The Company also entered into a sublease agreement through September 1999
for a total amount of $440,000. The appropriate amount has been offset against
the operating lease commitment for 2000, as shown above.

   The Company is a defendant in a lawsuit regarding an alleged trademark
infringement by the Company. Management believes the resolution of these
matters does not expect to have a material adverse effect on the financial
position of the Company. However, depending on the amount and

10. Note Receivable from Officer

   In June 1998, the Company entered into a loan agreement with an executive
officer of the Company. The loan agreement allows for borrowings by the officer
of up to $1,200,000 through June 2003. The note is full recourse and bears
interest at the minimum rate allowable by the Internal Revenue Service
(December 31, 1999: 5.69%). Principal and interest are due on the earlier of
five years from the date in which funds are borrowed or upon the officer's
receipt of proceeds from the sale of the Company's common stock owned by the
executive officer; 50% of such proceeds are due to the Company. As of December
31, 1999, principal and interest amounts due under this agreement were $376,000
and $23,000, respectively.

11. Related Party Transactions

   In February 2000, the Company entered into a memorandum of understanding
with four unrelated parties, under which the parties agreed to form a new
business, the purpose of which is to bring to market eCommerce ideas and
provide technical, strategic and financial assistance to start-up companies in
the financial service sector. For a period of six months after the formation of
this entity, the Company is committed to providing solution services to the new
entity for monthly service fees and ownership units in the new entity. In
return for these services, the Company is receiving cash and units in the
entity. The Company has recognized revenues only to the extent it receives
cash. The monthly service fees are to be billed at rates that approximate the
Company's billing rates for unrelated entities. Subsequent to the six month
period, any party can terminate this arrangement without penalties. In December
1999, prior to the formation of the memorandum of understanding, one of the
parties to the agreement, a United Kingdom company, engaged the Company to
provide certain consulting services on behalf of the new business. During the
year ending December 31, 1999, the Company recognized $373,000 in revenues
associated with this arrangement.

12. Retirement Plan

   The Company has a retirement plan under section 401(k) of the Internal
Revenue Code (the "Plan") covering substantially all of its full-time employees
who are age 21 or older. Employees may make voluntary contributions to the
Plan, which are subject to certain statutory limitations. Employees may
contribute up to an annual maximum of the lesser of 15% of eligible
compensation or $10,000 for the year ended December 31, 1999. The Company made
no contributions to the Plan during the years ended December 31, 1997, 1998 or
1999.

13. Subsequent Events

Proposed Public Offering of Common Stock

   In March 2000, the Company's board of directors authorized the Company to
file a registration statement with the Securities and Exchange Commission for
the purpose of an initial public offering of its common stock. Upon completion
of the Company's initial public offering as currently

anticipated, all of the outstanding preferred stock will be converted into
shares of common stock. The unaudited pro forma stockholders' equity at
December 31, 1999 gives effect to the conversion of all outstanding shares of
redeemable convertible preferred stock at that date into 13,622,932 shares of
common stock upon the completion of the offering.

Reincorporation

   In connection with the Company's reincorporation in the State of Delaware,
the Board of Directors authorized an increase in the number of authorized
shares of common stock to 100,000,000 shares and a decrease in the numbers of
authorized preferred stock to 5,000,000 shares.

Stock Split

   On March 8, 2000, the Board of Directors approved a two-for-three reverse
stock split of issued and outstanding common and preferred stock to be
effective prior to the completion of the initial public offering of its common
stock. All shares and related amounts in the accompanying financial statements
have been retroactively adjusted to reflect the stock split.

2000 Stock Plan

   In March 2000, the Board of Directors adopted, subject to stockholder
approval, the 2000 Stock Plan and reserved an aggregate 3,000,000 shares of
common stock for grants of stock options under such Plan. Upon the completion
of the Company's initial public offering as currently anticipated, the
Company's current Plan will terminate and no further options will be granted
under that Plan.

2000 Director Option Plan

   In March 2000, the Board of Directors adopted, subject to stockholder
approval, the 2000 Director Option Plan and reserved an aggregate 400,000
shares of common stock for grants of stock options under such Plan.

2000 Employee Stock Purchase Plan

   In March 2000, the Board of Directors adopted, subject to stockholder
approval, the 2000 Employee Stock Purchase Plan, to be effective upon the
completion of the Company's initial public offering of its common stock. The
Company has reserved a total of 750,000 shares of common stock for issuance
under the plan. Eligible employees may purchase common stock at 85% of the
lesser of the fair market value of the Company's common stock on the first or
last day of the applicable six-month purchase period.

Series D Preferred Stock

   In March 2000, the Company issued 743,200 shares of Series D preferred stock
to new and current investors for $9.65 per share. The rights of the Series D
preferred stockholders are similar to those of the Series A, B and C preferred
stockholders. In the event of liquidation, the holders of Series D preferred
stock, along with the holders of Series C preferred stock, in preference to the
holders of common stock and Series A and B preferred stock, will receive their
original purchase price plus any declared but unpaid dividends. The holders of
not less than two-thirds of the shares of Series A, B, C and D preferred stock
may elect to have the company redeem the preferred stock at the original issue
price beginning March 2008.

                   NOTES TO FINANCIAL STATEMENTS--(Continued)


   The $9.65 per share price of Series D preferred stock does not necessarily
represent the fair value of the preferred stock issued. In March 2000, the
Company will record an increase to the net loss available to common
stockholders of approximately $260,120, which represents the difference between
the $9.65 per share purchase price and deemed fair value of $10.00 per share.

   As a result of this transaction, the warrants issued in connection with the
line of credit (Note 7), became exercisable into 112,114 shares of Series D
preferred stock at $6.76 per share.

Sale of Common Stock

   In March 2000, the Company sold 300,000 shares of its common stock for $5.25
per share to two directors for proceeds of $1,575,000.

Item 14. Indemnification of Directors and Officers

   As permitted by Section 145 of the Delaware General Corporation Law, the
registrant's amended and restated certificate of incorporation includes a
provision that eliminates the personal liability of its directors for monetary
damages for breach or alleged breach of their duty of care. In addition, as
permitted by Section 145 of the Delaware General Corporation Law, the bylaws of
the registrant provide that: (1) the registrant is required to indemnify its
directors and executive officers and persons serving in such capacities in
other business enterprises at the registrant's request, to the fullest extent
permitted by Delaware law, including in those circumstances in which
indemnification would otherwise be discretionary; (2) the registrant may, in
its discretion, indemnify employees and agents in those circumstances where
indemnification is not required by law; (3) the registrant is required to
advance expenses, as incurred, to its directors and executive officers in
connection with defending a proceeding, except that it is not required to
advance expenses to a person against whom the registrant brings a claim for
breach of the duty of loyalty, failure to act in good faith, intentional
misconduct, knowing violation of law or deriving an improper personal benefit;
(4) the rights conferred in the bylaws are not exclusive, and the registrant is
authorized to enter into indemnification agreements with its directors,
executive officers and employees; and (5) the registrant may not retroactively
amend the bylaw provisions in a way that is adverse to such directors,
executive officers and employees in these matters. The registrant's policy is
to enter into indemnification agreements with each of its directors and
executive officers that provide the maximum indemnity allowed to directors and
executive officers by Section 145 of the Delaware General Corporation Law and
the bylaws, as well as certain additional procedural protections. In addition,
such indemnification agreements provide that the registrant's directors and
executive officers will be indemnified to the fullest possible extent not
prohibited by law against all expenses, including attorney's fees, and
settlement amounts paid or incurred by them in any action or proceeding,
including any derivative action by or in the right of the registrant, on
account of their services as directors or executive officers of the registrant
or as directors or officers of any other

                                      II-1
<PAGE>

company or enterprise when they are serving in such capacities at the request
of the registrant. The registrant will not be obligated pursuant to the
indemnification agreements to indemnify or advance expenses to an indemnified
party with respect to proceedings or claims initiated by the indemnified party
and not by way of defense, except with respect to proceedings specifically
authorized by the registrant's board of directors or brought to enforce a right
to indemnification under the indemnification agreement, the registrant's bylaws
or any statute or law. Under the agreements, the registrant is not obligated to
indemnify the indemnified party (1) for any expenses incurred by the
indemnified party with respect to any proceeding instituted by the indemnified
party to enforce or interpret the agreement, if a court of competent
jurisdiction determines that each of the material assertions made by the
indemnified party in such proceeding was not made in good faith or was
frivolous; (2) for any amounts paid in settlement of a proceeding unless the
registrant consents to such settlement; (3) with respect to any proceeding
brought by the registrant against the indemnified party for willful misconduct,
unless a court determines that each of such claims was not made in good faith
or was frivolous; (4) on account of any suit in which judgment is rendered
against the indemnified party for an accounting of profits made from the
purchase or sale by the indemnified party of securities of the registrant
pursuant to the provisions of (S)16(b) of the Securities Exchange Act of 1934,
and related laws; (5) on account of the indemnified party's conduct which is
finally adjudged to have been knowingly fraudulent or deliberately dishonest,
or to constitute willful misconduct or a knowing violation of the law; (6) an
account of any conduct from which the indemnified party derived an improper
personal benefit; (7) on account of conduct the indemnified party believed to
be contrary to the best interests of the registrant or its stockholders; (8) on
account of conduct that constituted a breach of the indemnified party's duty of
loyalty to the registrant or its stockholders; or (9) if a final decision by a
court having jurisdiction in the matter shall determine that such
indemnification is not lawful.

   The indemnification provision in the bylaws and the indemnification
agreements entered into between the registrant and its directors and executive
officers may be sufficiently broad to permit indemnification of the
registrant's officers and directors for liabilities arising under the
Securities Act of 1933.

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

Item 17. Undertakings

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

                                      II-5

   Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions referenced in Item 14 of this
registration statement or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933, 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 Securities Act of 1933 and will be
governed by the final adjudication of such issue.

   The undersigned registrant hereby undertakes that:

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

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

                         CERTIFICATE OF INCORPORATION

                                      OF

                                 2BRIDGE, INC.

                                      I.

     The name of this corporation is 2Bridge, Inc. (the "Corporation").

                                      II.

     The address of the Corporation's registered office in the State of Delaware
is 1209 Orange Street, City of Wilmington, County of New Castle, Delaware 19801.
The name of its registered agent at such address is The Corporation Trust
Company.

                                     III.

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

                                      IV.

     The Corporation is authorized to issue two classes of shares to be
designated respectively Common Stock, par value $0.0001 per share (the "Common
Stock"), and Preferred Stock, par value $0.0001 per share (the "Preferred
Stock"). The total number of shares of Common Stock the Corporation shall have
authority to issue is 47,000,000. The total number of shares of Preferred Stock
the Corporation shall have authority to issue is 23,868,514: 3,871,300 of which
shares shall be designated Series A Preferred Stock ("Series A Preferred"),
7,797,214 of which shares shall be designated Series B Preferred Stock ("Series
B Preferred"), 9,700,000 of which shares shall be designated Series C Preferred
Stock ("Series C Preferred") and 2,500,000 of which shares shall be designated
Series D Preferred Stock ("Series D Preferred").

     Upon the automatic conversion of all outstanding shares of Preferred Stock
in accordance with the provisions of Article IV, Section 4(a)(2) of this
Certificate of Incorporation (the "Automatic Conversion Event"), the Company
shall immediately thereafter be authorized to issue two classes of stock to be
designated, respectively, Common Stock, par value $0.0001 per share, and
Preferred Stock, par value $0.0001 per share. After the Automatic Conversion
Event, the total number of shares of Common Stock the Corporation shall have
authority to issue shall be 100,000,000, and the total number of shares of
Preferred Stock the Company shall have the authority to issue shall be
5,000,000. After the Automatic Conversion Event, the Preferred Stock may be
issued from time to time in one or more series pursuant to a resolution or
resolutions providing for such issue duly adopted by the Board of Directors
(authority to do so being hereby expressly vested
<PAGE>

in the Board of Directors). With respect to such series, the Board of Directors
is authorized (i) to determine the number of shares of any such series and the
designation thereof, (ii) to determine or alter the rights, preferences,
privileges and restrictions granted to or imposed upon any wholly unissued
series of Preferred Stock and (iii) 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, to increase (but not above the total
number of authorized shares of the class) or decrease (but not below the number
of shares of such series then outstanding) the number of shares of any such
series subsequent to the issue of shares of that series.

     Immediately following any Automatic Conversion Event, the Board of
Directors is authorized, without the further consent or approval of the
stockholders of the Company, to amend and restate this Certificate of
Incorporation to show the authorized classes of capital stock as set forth in
the preceding paragraph and to eliminate all references in this Certificate of
Incorporation to the rights, preferences, privileges and restrictions of the
series of Preferred Stock converted to Common Stock (and, in connection with any
such amendment and restatement, to renumber the remaining provisions of the
Certificate of Incorporation).

     The Corporation shall from time to time in accordance with the laws of the
State of Delaware increase the authorized amount of its Common Stock if at any
time the number of shares of Common Stock remaining unissued and available for
issuance shall not be sufficient to permit conversion of the Preferred Stock.

     The relative rights, preferences, privileges and restrictions granted to or
imposed on the respective classes of the shares of capital stock or the holders
thereof are as follows:

          1.   Voting Rights.
               -------------

               (a)  Except as otherwise provided in this Certificate of
Incorporation or as required by law, the holders of the Preferred Stock will be
entitled to notice of any meeting of stockholders of the Corporation and to vote
upon any matter submitted to stockholders or a class of stockholders that
includes the Preferred Stock on the following basis: each share of Preferred
Stock will be treated as the number of shares of Common Stock into which such
share could be converted on the record date fixed for the vote or consent of
stockholders.

               (b)  So long as at least 2,000,000 shares of Series C Preferred
are outstanding, the holders of outstanding shares of Series C Preferred will be
entitled, voting as a separate class, to elect one (1) director. So long as at
least 2,000,000 shares of Series B Preferred are outstanding, the holders of
outstanding shares of Series B Preferred will be entitled, voting as a separate
class, to elect one (1) director. So long as at least 1,250,000 shares of Series
A Preferred are outstanding, the holders of outstanding shares of Series A
Preferred will be entitled, voting as a separate class, to elect two (2)
directors. So long as either the holders of Series A Preferred, Series B
Preferred, or Series C Preferred have the right to elect a director, the holders
of outstanding shares of Common Stock, voting as a separate class, will be
entitled to elect one (1) director, and the holders of Common Stock and Series D
Preferred, voting together as a class, will be entitled to elect one (1)
director. Any remaining members of the Board of Directors of the Corporation
shall be elected by

                                      -2-
<PAGE>

holders of outstanding shares of Common Stock and Preferred Stock, voting
together as a single class. Any director elected solely by the holders of a
particular class or series of stock, may be removed, either with or without
cause, by, and only by, the affirmative vote of the holders of a majority of the
shares of that class or series of stock, either at a special meeting of such
stockholders duly called for that purpose or pursuant to a written consent of
stockholders, and any vacancy thereby created or otherwise resulting may be
filled by, and only by, the holders of the class or series of stock whose right
to such Board of Directors position are affected by such vacancy.

               (c)  Except as otherwise required by law or provided by in the
Corporation's Articles of Incorporation, a majority of the shares entitled to
vote, represented in person or by proxy, will constitute a quorum at a meeting
of stockholders; provided that for action upon any matter as to which holders of
shares are entitled to vote as a class, a majority of the shares of such class,
represented in person or by proxy, will constitute a quorum.

          2.   Dividends. The holders of the Preferred Stock will be entitled to
               ---------
receive, when, as and if declared by the Board of Directors out of any assets at
the time legally available therefor, noncumulative cash dividends at the rate of
five percent (5%) of the Original Purchase Price (as defined in Section 3(a)
below) per annum per share of Preferred Stock (as appropriately adjusted for
stock splits or combinations of the Preferred Stock). No dividend shall be
declared or paid or other distributions made (other than those payable solely in
shares of Common Stock) with respect to the Common Stock during any fiscal year
of the Corporation until any declared dividends in the aforesaid amounts on the
outstanding shares of Preferred Stock shall have been paid in such fiscal year.
The holders of the Preferred Stock will also be entitled to participate pro rata
in any dividends paid on the Common Stock on an as-if-converted into Common
Stock basis.

          3.   Liquidation Preference.
               ----------------------

               (a)  For purposes hereof, the "Original Purchase Price" of the
Series A Preferred is $0.8718 per share, and the "Original Issue Date" is the
effective date of the initial sale of Series A Preferred. The "Original Purchase
Price" of the Series B Preferred is $1.4081 per share, and the "Original Issue
Date" is the effective date of the initial sale of Series B Preferred. The
"Original Purchase Price" of the Series C Preferred is $2.1328 and the "Original
Issue Date" is the effective date of the initial sale of Series C Preferred. The
"Original Purchase Price" of the Series D Preferred is $6.4347 per share, and
the "Original Issue Date" is the effective date of the initial sale of the
Series D Preferred.

               (b)  In the event of the liquidation, dissolution or winding up
of the Corporation, either voluntary or involuntary, the following shall apply:

                    (1)  For each share of the Series C Preferred or Series D
Preferred then held, the holders of the Series C Preferred and Series D
Preferred shall be entitled to receive, prior and in preference to any
distribution of any of the assets or surplus funds of the Corporation to any
other holders of the Preferred Stock or Common Stock by reason of their
ownership thereof, an amount equal to the Original Purchase Price of the Series
C Preferred or Series D Preferred, as the case may be (as appropriately adjusted
for stock splits, stock dividends, recapitalizations,

                                      -3-
<PAGE>

combinations and the like (collectively "Recapitalizations")) plus all declared
and unpaid dividends with respect thereto (the "Series C and Series D
Liquidation Preference"). If, upon occurrence of such event the assets and funds
thus distributed among the holders of the Series C Preferred and the Series D
Preferred shall be insufficient to permit the payment to the holders of the
Series C Preferred and the Series D Preferred of the full Series C and D
Liquidation Preference, then the entire assets and funds of the Corporation
legally available for distribution shall be distributed ratably, on an equal
priority, pari passu basis among the holders of Series C Preferred and Series D
Preferred based on their relative preferential amounts;

                    (2)  After the payment of the Series C and D Liquidation
Preference for each share of the Series A Preferred or Series B Preferred then
held, the holders of the Series A Preferred and Series B Preferred shall be
entitled to receive, prior and in preference to any distribution of any assets
or surplus funds of the Corporation to any holders of the Common Stock by reason
of their ownership thereof, an amount equal to the Original Purchase Price of
the Series A Preferred or Series B Preferred (as appropriately adjusted for any
Recapitalizations) plus all declared and unpaid dividends with respect thereto
(the "Series A and B Liquidation Preference"). If, upon occurrence of such event
the assets and funds thus distributed among the holders of the Series A
Preferred and the Series B Preferred shall be insufficient to permit payment to
the holders of the Series A Preferred and the Series B Preferred of the full
Series A and B Liquidation Preference, then, after the payments required by
Section 3(b)(1) above shall have been made, the entire assets and funds of the
Corporation legally available for distribution shall be distributed ratably, on
an equal priority, pari passu basis among the holders of Series A Preferred and
Series B Preferred based on their relative preferential amounts;

                    (3)  After the payment of the Series C and D Liquidation
Preference and Series A and B Liquidation Preference to the holders of the
Series A Preferred, Series B Preferred, Series C Preferred and Series D
Preferred, the holders of the Preferred Stock and the holders of the Common
Stock will then be entitled to receive their pro rata share (on an as-converted
basis) of the remaining assets and funds of the Corporation until the holders of
the Series A Preferred have received, in the aggregate, $1.3077 per share, the
Series B Preferred holders have received, in the aggregate, $2.1122 per share,
the Series C Preferred holders have received, in the aggregate, $2.666 per
share, and the Series D Preferred holders have received, in the aggregate,
$8.0375 per share (including the Series A and B Liquidation Preference and the
Series C and D Liquidation Preference, as applicable).

                    (4)  then, after payment has been made to the holders of the
Preferred Stock of the full amounts to which they are entitled as set forth in
clauses (1), (2), and (3) of this Section 3(b), all remaining assets and funds
of the Corporation will be distributed ratably among the holders of the
Corporation's Common Stock.

               (c)  A liquidation, dissolution or winding up for the purposes of
this Section 3 includes (i) a sale, lease or disposition of all or substantially
all of the assets of the Corporation, (ii) a merger or consolidation of the
Corporation with or into any other corporation or corporations or other entity,
or any other corporate reorganization, where the stockholders of the

                                      -4-
<PAGE>

Corporation immediately prior to such event do not obtain or retain in excess of
fifty percent (50%) interest in the outstanding equity of the successor entity,
and (iii) the sale by the stockholders to any other corporation or corporations
or other entity or entities, or person or persons,of in excess of fifty percent
(50%) of the then outstanding shares (on an as-converted into Common Stock
basis) of the Corporation's stock.

          4.   Conversion Rights.
               -----------------

               (a)  Right to Convert.
                    ----------------

                    (1)  Optional Conversion. Each share of Preferred Stock will
                         -------------------
be convertible, at the option of the holder thereof, at the office of the
Corporation or any transfer agent for the Preferred Stock, into Common Stock.
The number of shares of Common Stock into which each share of Preferred Stock
will be converted will be equal to the Original Purchase Price of Series A
Preferred, Series B Preferred, Series C Preferred or Series D Preferred as
applicable, divided by the Conversion Price (as hereafter defined) for such
Series A Preferred, Series B Preferred, Series C Preferred or Series D
Preferred, such conversion ratio being referred to as the "Conversion Rate." The
initial Conversion Price for Series A Preferred will be the Original Purchase
Price of Series A Preferred, the initial Conversion Price for the Series B
Preferred will be the Original Purchase Price of Series B Preferred, the initial
Conversion Price for Series C Preferred will be the Original Purchase Price of
Series C Preferred and the initial Conversion Price for the Series D Preferred
will be the Original Purchase Price of Series D Preferred. Upon any decrease or
increase of the Conversion Price or the Conversion Rate for Series A Preferred,
Series B Preferred, Series C Preferred or Series D Preferred, as described in
this Section 4, the Conversion Rate or Conversion Price, as the case may be, for
Series A Preferred, Series B Preferred, Series C Preferred or Series D
Preferred, will be increased or decreased appropriately.

                    (2)  Automatic Conversion of Preferred Stock. Each share of
                         ---------------------------------------
Preferred Stock automatically will be converted into shares of Common Stock at
the then effective Conversion Rate at the earlier of:

                         (i)  in the case of the Series A Preferred, the
voluntary conversion or consent to conversion of at least a majority of the
outstanding shares of Series A Preferred; in the case of the Series B Preferred,
the voluntary conversion or consent to conversion of at least a majority of the
outstanding shares of Series B Preferred; in the case of the Series C Preferred,
the voluntary conversion or consent to conversion of at least a majority of the
outstanding shares of Series C Preferred; and in the case of the Series D
Preferred, the voluntary conversion or consent to conversion of at least a
majority of the outstanding shares of Series D Preferred; or

                         (ii) immediately upon the closing of the sale of stock
pursuant to a registration statement under the Securities Act of 1933, as
amended, for a firm commitment underwritten public offering (other than a
registration on Form S-8, Form S-4 or comparable forms) covering the
Corporation's Common Stock which results in aggregate cash proceeds (prior to
underwriters' commissions and expenses) to the Corporation of at least twenty
million dollars ($20,000,000), after deduction of underwriting discounts and
commission and

                                      -5-
<PAGE>

offering expenses and which has a public offering price of not less than five
dollars ($5.00) per share (as appropriately adjusted for any Recapitalizations).

Upon such automatic conversion, any declared and unpaid dividends shall be paid
in accordance with the provisions of Section 4(b)of this Article IV.

                    (3)  Fractional Shares Upon Conversion. No fractional shares
                         ---------------------------------
of Common Stock will be issued upon conversion of Preferred Stock and any
fractional share which otherwise would result from conversion by a holder of all
of the holder's shares of Preferred Stock (taken together as a group) will be
redeemed by payment in an amount equal to such fraction of the then effective
Conversion Price as promptly as funds legally are available therefor.

               (b)  Mechanics of Conversion. Upon conversion, the holder of
                    -----------------------
Preferred Stock will surrender the certificate or certificates therefor, duly
endorsed, at the office of the Corporation or of any transfer agent for the
Preferred Stock, and will give written notice to the Corporation stating the
name or names in which the holder wishes the certificate or certificates for
shares of Common Stock to be issued; provided, however, that in the event of an
automatic conversion pursuant to this paragraph (b), the outstanding shares of
Preferred Stock shall be converted automatically without any further action by
the holders of such shares and whether or not the certificates representing such
shares are surrendered to the Corporation or its transfer agent; provided,
further, that the Corporation shall not be obligated to issue certificates
evidencing the shares of Common Stock issuable upon such automatic conversion
unless either the certificates evidencing such shares of Preferred Stock are
delivered to the Corporation or its transfer agent as provided above, or the
Preferred Stockholder notifies the Corporation or its transfer agent that such
certificates have been lost, stolen or destroyed and executes an agreement
satisfactory to the Corporation to indemnify the Corporation from any loss
incurred by it in connection with such certificates. The Corporation, as soon as
practicable thereafter, will issue and deliver at such office to such holder of
Preferred Stock or to such holder's nominee or nominees, a certificate or
certificates for the number of shares of Common Stock to which the holder will
be entitled as aforesaid, and the Corporation shall promptly pay in cash, or to
the extent sufficient funds are not legally available therefor, in Common Stock
(at the Common Stock's fair market value determined by the Board of Directors as
of the date of such conversion), any declared and unpaid dividends on the shares
of Preferred Stock being converted. Any conversion will be deemed to have been
made immediately prior to the close of business on the date of the event of
conversion, in the event of automatic conversion hereunder, or, in the event of
voluntary conversion, immediately prior to the close of business on the date
when the Corporation receives a holder's certificate or certificates for the
Preferred Stock and any other documents or instruments required hereunder or by
applicable law, and the person or persons entitled to receive the shares of
Common Stock issuable upon conversion will be treated for all purposes as the
record holder or holders of such shares of Common Stock on such date. If the
conversion is in connection with an underwritten offering of securities
registered pursuant to the Securities Act the conversion may, at the option of
any holder tendering such Preferred Stock for conversion, be conditioned upon
the closing with the underwriters of the sale of securities pursuant to such
offering, in which event the person(s) entitled to receive Common Stock

                                      -6-
<PAGE>

upon conversion of such Preferred Stock shall not be deemed to have converted
such Preferred Stock until immediately prior to the closing of such sale of
securities.

               (c)  Adjustment for Subdivisions or Combinations of Common Stock.
                    -----------------------------------------------------------
In the event the Corporation at any time or from time to time after the Original
Issue Date effects a subdivision or combination of its outstanding Common Stock
into a greater or lesser number of shares without a proportionate and
corresponding subdivision or combination of its outstanding Preferred Stock,
then the existing Conversion Price for the Series A Preferred, the Series B
Preferred, the Series C Preferred and Series D Preferred, respectively, will be
decreased or increased proportionately.

               (d)  Adjustment for Dividends, Distributions and Common Stock
                    --------------------------------------------------------
Equivalents. In the event the Corporation at any time or from time to time
- -----------
after the Original Issue Date makes or issues, or fixes a record date for the
determination of holders of Common Stock (but not holders of the Preferred
Stock) entitled to receive a dividend or other distribution payable in
additional shares of Common Stock or other securities or rights (hereinafter
referred to as "Common Stock Equivalents") convertible into or entitling the
holder thereof to receive additional shares of Common Stock without payment of
any consideration by such holder for such Common Stock Equivalents or the
additional shares of Common Stock, then and in each such event the maximum
number of shares (as set forth in the instrument relating thereto without regard
to any provisions contained therein for a subsequent adjustment of such number)
of Common Stock issuable in payment of such dividend or distribution or upon
conversion or exercise of such Common Stock Equivalents will be deemed to be
issued and outstanding as of the time of such issuance or, in the event such a
record date has been fixed, as of the close of business on such record date. In
each such event, the then existing Conversion Rate for each series of Preferred
Stock will be increased as of the time of such issuance or, in the event such a
record date has been fixed, as of the close of business on such record date, by
multiplying the Conversion Rate for the Series A Preferred, Series B Preferred,
Series C Preferred or Series D Preferred as applicable, by a fraction:

                         (i)  the numerator of which will be the total number of
shares of Common Stock issued and outstanding (or so deemed) immediately prior
to the time of such issuance or the close of business on such record date plus
the number of shares of Common Stock issuable in payment of such dividend; and

                         (ii) the denominator of which will be the total number
of shares of Common Stock issued and outstanding (or so deemed) immediately
prior to the time of such issuance or the close of business on such record date;
provided that if such record date has been fixed and such dividend is not fully
paid or if such distribution is not fully made on the date fixed therefor, the
Conversion Rate for the Preferred Stock will be recomputed accordingly as of the
close of business on such record date and thereafter the Conversion Rate for
each series of Preferred Stock will be adjusted pursuant to this Section 4(d) as
of the time of actual payment of such dividends or distribution.

               (e)  Adjustment for Sale of Shares. If at any time after the
                    -----------------------------
Original Issue Date, the Corporation issues or sells any shares of its Common
Stock (other than shares of Common

                                      -7-
<PAGE>

Stock (i) issued on conversion of Preferred Stock; (ii) issued either directly
or upon exercise of options or warrants or issuance of shares of Common Stock to
employees, officers, directors and independent contractors of the Corporation
and its subsidiaries pursuant to stock purchase or stock option plans,
agreements or other similar arrangements that are approved unanimously by the
Board of Directors (the "Compensatory Shares"); or (iii) issued either directly
or upon exercise of options or warrants issued in connection with equipment
lease financing or other similar financing arrangements approved unanimously by
the Board of Directors (the "Lease Financing Shares")) for a consideration per
share less than the then effective Conversion Price, then and in each such case,
the Conversion Price for the Series A Preferred, the Series B Preferred, the
Series C Preferred and the Series D Preferred, respectively, will be reduced to
a price (calculated to the nearest cent) determined by multiplying such
applicable Conversion Price by a fraction (a) the numerator of which will be the
number of shares of Common Stock outstanding (or issuable upon conversion of the
Preferred Stock) immediately prior to such issuance or sale plus the number of
shares of Common Stock which the aggregate consideration received by the
Corporation for such issuance or sale would purchase at such applicable
Conversion Price, and (b) the denominator of which will be the number of shares
of Common Stock outstanding (or issuable upon conversion of the Preferred Stock)
immediately after the Common Stock proposed to be issued or sold is issued or
sold; provided that such fraction will in no event be greater than one (1). For
purposes of this Section 4(e), the shares of Common Stock issuable upon
conversion of the Preferred Stock (without regard to adjustments in this Section
4(e)), the Compensatory Shares (to the extent issued or subject to outstanding
options), and the Lease Financing Shares (to the extent issued or subject to
outstanding options) will be deemed to be outstanding on the Original Issue
Date.

     For the purpose of making any adjustment in the Conversion Price as
provided above, the consideration received by the Corporation for any issuance
or sale of Common Stock will be computed:

                    (1)  to the extent it consists of cash, as the amount of
cash received by the Corporation before deduction of any offering expenses
payable by the Corporation and any underwriting or similar commissions,
compensation, or concessions paid or allowed by the Corporation in connection
with such issuance or sale;

                    (2)  to the extent it consists of property other than cash,
at the fair market value of that property as determined in good faith by the
Corporation's Board of Directors; and

                    (3)  if Common Stock is issued or sold together with other
stock or securities or other assets of the Corporation for a consideration which
covers both, as the portion of the consideration so received that may be
reasonably determined in good faith by the Board of Directors to be allocable to
such Common Stock.

     If the Corporation (a) grants any rights or options (other than rights or
options issued in connection with the Compensatory Shares and Lease Financing
Shares as described above) to subscribe for, purchase, or otherwise acquire
shares of Common Stock, or (b) issues or sells any security convertible into
shares of Common Stock, then, in each case, the price per share of

                                      -8-
<PAGE>

Common Stock issuable on the exercise of the rights or options or the conversion
of the securities will be determined by dividing the total amount, if any,
received or receivable by the Corporation as consideration for the granting of
the rights or options or the issuance or sale of the convertible securities,
plus the minimum aggregate amount of additional consideration payable to the
Corporation on exercise or conversion of the securities, by the maximum number
of shares of Common Stock issuable on such exercise or conversion. Such granting
or issuance or sale will be considered to be an issuance or sale for cash of the
maximum number of shares of Common Stock issuable on exercise or conversion at
the price per share determined under this subsection, and the Conversion Price
for the Series A Preferred, Series B Preferred, Series C Preferred or Series D
Preferred, as applicable, will be adjusted as above provided to reflect (on the
basis of that determination) the issuance or sale. No further adjustment of the
Conversion Price for the Series A Preferred, Series B Preferred, Series C
Preferred or Series D Preferred will be made as a result of the actual issuance
of shares of Common Stock on the exercise of any such rights or options or the
conversion of any such convertible securities, except as set forth below.

     Upon the redemption or repurchase of any such securities or the expiration
or termination of the right to convert into, exchange for, or exercise with
respect to, Common Stock, the Conversion Price for the Series A Preferred,
Series B Preferred, Series C Preferred or Series D Preferred will be readjusted
to such price as would have been obtained had the adjustment made upon their
issuance been made upon the basis of the issuance of only the number of such
securities as were actually converted into, exchanged for, or exercised with
respect to, Common Stock. If the purchase price or conversion or exchange rate
provided for in any such security changes at any time, then, upon such change
becoming effective, the Conversion Price for the Series A Preferred, Series B
Preferred, Series C Preferred or Series D Preferred then in effect will be
readjusted forthwith to such price as would have been obtained had the
adjustment made upon the issuance of such securities been made upon the basis of
(a) the issuance of only the number of shares of Common Stock theretofore
actually delivered upon the conversion, exchange or exercise of such securities,
and the total consideration received therefor, and (b) the granting or issuance,
at the time of such change, of any such securities then still outstanding for
the consideration, if any, received by the Corporation therefor and to be
received on the basis of such changed price or rate.

               (f)  Recapitalizations. If at any time or from time to time there
                    -----------------
shall be a Recapitalization of the Common Stock, Series A Preferred, Series B
Preferred, Series C Preferred or Series D Preferred (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 4), provision shall be made so that the holders of the Preferred
Stock will thereafter be entitled to receive upon conversion of the Preferred
Stock the number of shares of stock or other securities or property of the
Corporation or otherwise, to which a holder of Common Stock would have been
entitled on such recapitalization. In any such case, appropriate adjustment
shall be made in the application of the provisions of this Section 4 with
respect to the rights of the holders of the Preferred Stock after the
recapitalization to the end that the provisions of this Section 4 (including
adjustment of the Conversion Price then in effect and the number of shares
issuable upon conversion of the Series A Preferred, Series B Preferred, Series C
Preferred and Series D Preferred) shall be applicable after that event in as
nearly an equivalent manner as may be practicable.

                                      -9-
<PAGE>

               (g)  No Impairment. Without the consent of the holders of the
                    -------------
Preferred Stock, as set forth in Section 6 below, the Corporation, whether by
amendment of its Certificate of Incorporation or through any reorganization,
transfer of assets, merger, dissolution, issue or sale of securities or any
other voluntary action, will not avoid or seek to avoid the observance or
performance of any of the terms to be observed or performed hereunder by the
Corporation, but at all times in good faith will assist in the carrying out of
all of such action as may be necessary or appropriate in order to protect the
conversion rights pursuant to this Section 4 of the holders of the Preferred
Stock against dilution or other impairment.

               (h)  Certificate as to Adjustments. Upon the occurrence of each
                    -----------------------------
adjustment or readjustment of the Conversion Rate pursuant to this Section 4,
the Corporation at its expense promptly will 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, upon the written request at any time of
any holder of Preferred Stock, will furnish or cause to be furnished to such
holder a like certificate setting forth (i) such adjustments and readjustments,
(ii) the Conversion Rate for the Series A Preferred, Series B Preferred, Series
C Preferred or Series D Preferred, as applicable, 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 conversion of the
Preferred Stock held by such holder.

               (i)  Notices of Record Date. In the event that the Corporation
                    ----------------------
shall propose at any time:

                    (1)  to declare any dividend or distribution upon its Common
Stock, whether in cash, property, stock or other securities, whether or not a
regular cash dividend and whether or not out of earnings or earned surplus;

                    (2)  to offer for subscription pro rata to the holders of
any class or series of its stock any additional shares of stock of any class or
series or any other similar rights;

                    (3)  to effect any reclassification or recapitalization of
its Common Stock outstanding which results in a change in the Common Stock; or

                    (4)  a liquidation, dissolution or winding up as described
in Section 3(c) of this Article IV;

     Then, in connection with each such event, the Corporation shall send a
written notice, pursuant to Section 4(k) below, to the holders of the Preferred
Stock as follows:

                    (1)  at least 20 days prior to the date on which a record
shall be taken for such dividend, distribution or subscription offer (and
specifying the date on which the holders of Common Stock shall be entitled
thereto) or for determining rights to vote on the matters referred to in clauses
(3) and (4) above; and

                                      -10-
<PAGE>

                    (2)  in the case of the matters referred to in clauses (3)
and (4) above, at least 20 days prior to the date when the same shall take place
and specifying the date on which the holders of Common Stock shall be entitled
to exchange their Common Stock for securities or other property deliverable upon
the occurrence of such event or the record date for the determination of such
holders if such record date is earlier.

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

               (k)  Notices. Any notices required by the provisions of this
                    -------
Section 4 to be given to the holders of the Preferred Stock must be in writing
and will be deemed given upon personal delivery, one day after deposit with a
reputable overnight courier service for overnight delivery or after transmission
by facsimile telecopier with confirmation of successful transmission, or five
days after deposit in the United States mail, by registered or certified mail
postage prepaid, or upon actual receipt if given by any other method, addressed
to each holder of such record at the holder's address appearing on the books of
the Corporation.

          5.   Redemption.
               ----------

               (a)  Redemption Election. The holders of not less than two-thirds
                    -------------------
of the outstanding shares of the Series A Preferred, Series B Preferred, Series
C Preferred or Series D Preferred, as applicable, may elect, on or after the
date eight years from the Original Issue Date of the Series B Preferred, by
written notice to the Corporation (the date of such written notice referred to
herein as the "Redemption Notice Date") to have the outstanding shares of the
Series A Preferred, Series B Preferred, Series C Preferred or Series D Preferred
redeemed by the Corporation pursuant to this Section 5.

               (b)  Redemption Schedule. In the event of the election referred
                    -------------------
to in Section 5(a) of this Article IV, the Corporation will redeem the Series A
Preferred, Series B Preferred, Series C Preferred or Series D Preferred,
according to the following schedule: (a) one-third of each holder's shares of
Series A Preferred, Series B Preferred, Series C Preferred or Series D
Preferred, as applicable, outstanding sixty days after the Redemption Notice
Date (the "Redemption Date") will be redeemed by the Corporation on the
Redemption Date (or if such date is not a business day, then the next business
day); (b) one-third of each holder's shares of Series A Preferred, Series B
Preferred, Series C Preferred or Series D Preferred, as applicable, outstanding
as of the first anniversary of the Redemption Date will be redeemed by the
Corporation on such first anniversary (or if such date is not a business day,
then the next business day); and (c) the balance of each holder's

                                      -11-
<PAGE>

shares of Series A Preferred, Series B Preferred, Series C Preferred or Series D
Preferred outstanding as of the second anniversary of the Redemption Date will
be redeemed by the Corporation on such second anniversary (or if such date is
not a business day, then the next business day). The Corporation shall effect
such redemptions on a pro rata basis on the applicable dates by paying in cash
in exchange for each share of Series A Preferred, Series B Preferred, Series C
Preferred or Series D Preferred to be redeemed a sum equal to the Redemption
Price (as defined below).

               (c)  Redemption Price. The amount per share payable upon such
                    ----------------
redemption of Preferred Stock will be the Original Purchase Price of the Series
A Preferred, Series B Preferred, Series C Preferred or Series D Preferred, as
applicable (as appropriately adjusted for any Recapitalizations), plus any
declared but unpaid dividends on such shares (the "Redemption Price").

               (d)  Redemption Notice. At least fourteen (14) days prior to the
                    -----------------
initial Redemption Date, written notice (the "Redemption Notice") will be
mailed, postage prepaid, to each holder of record of the Series A Preferred,
Series B Preferred, Series C Preferred or Series D Preferred at the holder's
address last shown on the records of the Corporation, specifying the Redemption
Price of the shares to be redeemed and the Redemption Date, and calling upon
such holder to surrender to the Corporation for redemption, in the manner and at
the place designated in the Redemption Notice, the holder's certificate or
certificates representing the shares of Preferred Stock being redeemed, and
thereupon the Redemption Price of such shares will be payable without interest
to the order of the person whose name appears on such certificate or
certificates as the owner thereof and each surrendered certificate will be
canceled to the extent redeemed.

               (e)  Insufficient Funds. If no funds or insufficient funds are
                    ------------------
legally available to redeem all of the shares of Preferred Stock then due to be
redeemed on a Redemption Date, then (i) the maximum possible number of shares of
Series A Preferred, Series B Preferred, Series C Preferred or Series D Preferred
permitted to be redeemed shall be so redeemed pro rata (based on aggregate
Redemption Price to be redeemed) among the holders of the Series A Preferred,
Series B Preferred, Series C Preferred or Series D Preferred, as applicable, and
(ii) any of such shares which are not redeemed shall be carried forward and
shall be redeemed (together with other shares of Preferred Stock which are then
due to be redeemed) at the next such redemption date scheduled under Section
5(b) of this Article IV to the full extent of legally available funds of the
Corporation at such time. Shares of Preferred Stock which are subject to
redemption, but which have not been redeemed due to insufficient legally
available funds, shall continue to be outstanding and entitled to all dividend,
liquidation, conversion and other rights, preferences, privileges and
restrictions of the Preferred Stock, until such shares have been converted or
redeemed and the Redemption Price has been paid or set aside with respect to
such shares. Any failure by the Corporation to comply with the redemption
procedures set forth in Section 5(b) of this Article IV shall not relieve the
Corporation of its obligations to redeem the shares of Preferred Stock under
this Section 5. Notwithstanding any election to be redeemed, any holder of any
Preferred Stock may convert such shares in accordance with Section 4 of this
Article IV at any time prior to the close of business on the business day next
preceding the applicable redemption date for such shares.

          6.   Covenants.
               ---------

               (a)  In addition to any other rights provided by law, so long as
any shares of Preferred Stock shall be outstanding, the Corporation, without
first obtaining the affirmative vote or written consent of the holders of not
less than a majority of such outstanding shares of Preferred Stock (with the
Series A Preferred, Series B Preferred, Series C Preferred and Series D
Preferred voting together as a single class), will not:

                    (1)  increase or decrease the authorized number of shares of
the Preferred Stock or the Common Stock;

                    (2)  apply any of its assets to the redemption, repurchase,
acquisition, payment of dividends or other distributions directly or indirectly,
through subsidiaries or otherwise, of any shares of any class or series of
equity securities (except for (i) redemption of any series of Preferred Stock
pursuant to Section 5 of this Article IV, or (ii) acquisitions of Common Stock
by the Corporation pursuant to agreements which permit the Corporation to
repurchase such shares upon termination of services to the Corporation or in
exercise of the Corporation's right of first refusal on a proposed transfer);

                    (3)  sell, lease or dispose of all or substantially all of
the assets of the Corporation, or effect a merger or consolidation of the
Corporation with or into any other corporation or corporations or other entity,
or any other corporate reorganization where the stockholders of the Corporation
immediately prior to such event do not obtain or retain a majority of the
outstanding equity in the successor entity; or

                    (4)  amend the Certificate of Incorporation or bylaws to
change the authorized number of directors of the Corporation's board of
directors.

               (b)  In addition to any other rights provided by law, so long as
any shares of Series A Preferred, Series B Preferred, Series C Preferred or
Series D Preferred, as applicable, shall be outstanding, the Corporation,
without first obtaining the affirmative vote or written consent of the holders
of not less than a majority of such outstanding shares of Series A Preferred,
Series B Preferred, Series C Preferred or Series D Preferred, (each voting as a
separate class), as applicable, will not:

                    (1)  amend or repeal any provision of, or add any provision
to, the Corporation's Certificate of Incorporation or bylaws if such action
would alter, change or waive any of the preferences, rights, privileges or
powers of, or the restrictions provided for the benefit of, the Series A
Preferred, Series B Preferred, Series C Preferred or Series D Preferred; or

                    (2)  create, whether by reclassification or otherwise, any
shares of any class or series of stock ranking senior to or on parity with the
Series A Preferred, Series B Preferred, Series C Preferred or Series D
Preferred, as to dividends, voting, liquidation preference, conversion or
redemption rights.

                                      V.

     To the fullest extent permitted by the General Corporation Law of the State
of Delaware as the same exists or may hereafter be amended, no director of the
Corporation shall be personally liable to the Corporation or its stockholders
for monetary damages for breach of fiduciary duty as a director.

     Neither any amendment, modification nor repeal of this Article, nor the
adoption of any provision of this Certificate of Incorporation inconsistent with
this Article, shall eliminate, reduce or adversely affect, any right or
protection of a director of the Corporation existing hereunder with respect to
any act or omission occurring prior to such amendment, modification, repeal or
adoption of an inconsistent provision.

                                      VI.

     Effective upon the closing of a firm commitment underwritten public
offering of Common Stock of the Corporation, no action that is required or
permitted to be taken by the stockholders of the Corporation at any annual or
special meeting of stockholders may be effected by written consent of
stockholders in lieu of a meeting of stockholders.

                                     VII.

     Effective upon the closing of a firm commitment underwritten public
offering of Common Stock of the Corporation, no stockholder will be permitted to
cumulate votes at any election of directors.

                                     VIII.

     Notwithstanding the foregoing, effective upon the closing of a firm
commitment underwritten public offering of Common Stock of the Corporation, the
Board of Directors shall be divided into three classes, the members of each
class to serve for a term of three years; provided that the directors shall be
elected as follows: at the first annual meeting of the stockholders held
following the closing of a firm commitment underwritten public offering of
Common Stock of the Corporation, the directors in the first class shall be
elected for a term of three years, at the second annual meeting following such
date, the directors in the second class shall be elected for a term of three
years, and at the third annual meeting following such date, the directors in the
third class shall be elected for a term of three years. The Board of Directors
by resolution shall nominate the directors to be elected for each class. At
subsequent annual meetings of stockholders, a number of directors shall be
elected equal to the number of directors with terms expiring at that annual
meeting. Directors elected at each such subsequent annual meeting shall be

     All notices of meetings of stockholders 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. The notice shall specify the
place, date and hour of the meeting and (i) in the case of a special meeting,
the purpose or purposes for which the meeting is called (no business other than
that specified in the notice may be transacted) or (ii) in the case of the
annual meeting, those matters which the Board of Directors, at the time of
giving the notice, intends to present for action by the stockholders (but any
proper matter may be presented at the meeting for such action). The notice of
any meeting at which directors are to be elected shall include the name of any
nominee or nominees who, at the time of the notice, the board intends to present
for election.

     2.5  ADVANCE NOTICE OF STOCKHOLDER NOMINEES AND STOCKHOLDER BUSINESS
          ---------------------------------------------------------------

     Nominations of persons for election to the Board of Directors of the
corporation may be made at a meeting of stockholders by or at the direction of
the Board of Directors, by any nominating committee or person appointed by the
Board of Directors or by any stockholder of the corporation entitled to vote in
the election of directors at the meeting who complies with the notice procedures
set forth in this Section and who was a stockholder of record at the time of the
giving of such notice. Such nominations, other than those made by or at the
direction of the Board of Directors or by any nominating committee or person
appointed by the Board of Directors, shall be made pursuant to timely notice in
writing to the Secretary of the corporation. To be timely, a stockholder's
notice shall be delivered to or mailed and received at the principal executive
offices of the corporation not less than sixty (60) days nor more than one
hundred twenty (120) days prior to the scheduled meeting regardless of any
postponements, deferrals or adjournments of that meeting to a later date;
provided, however, that in the event less than seventy (70) days notice or prior
public disclosure of the date of the meeting is given or made to stockholders,
notice by the stockholder to be timely must be so received not later than the
close of business on the tenth day following the day on which such notice of the
date of the meeting was mailed or such public disclosure was made. For purposes
of this Section 2.5 "public disclosure" shall mean disclosure in a press release
reported by the Dow Jones News Service, Associated Press or a comparable
national news service or in a document publicly filed by the corporation with
the Securities and Exchange Commission. Such stockholder's notice shall set
forth (a) as to each person, if any, whom the stockholder proposes to nominate
for election or re-election as a director: (i) the name, age, business address
and residence address of such person, (ii) the principal occupation or
employment of such person, (iii) the class and number of shares of the
corporation which are beneficially owned by such person, (iv) any other
information relating to such person that is required by law to be disclosed in
solicitations of proxies for election of directors pursuant to applicable rules
and regulations of the Securities and Exchange Commission promulgated under the
Securities Exchange Act of 1934, as amended, and (v) such person's written
consent to being named as a nominee and to serving as a director if elected; and
(b) as to the stockholder giving the notice: (i) the name and address, as they
appear on the corporation's books, of such stockholder, (ii) the class and
number of shares of the corporation

                                      -2-
<PAGE>

which are beneficially owned by such stockholder on the date of such stockholder
notice, and (iii) a description of all arrangements or understandings between
such stockholder and each nominee and any other person or persons (naming such
person or persons) relating to the nomination. At the request of the Board of
Directors any person nominated by the Board of Directors for election as a
director shall furnish to the Secretary of the corporation that information
required to be set forth in the stockholder's notice of nomination which
pertains to the nominee or required by the corporation to determine the
eligibility of such proposed nominee to serve as director of the corporation. No
person shall be eligible for election as a director of the corporation unless
nominated in accordance with the procedures set forth in this Section. The
chairman of the meeting shall, if the facts warrant, determine and declare at
the meeting that a nomination was not made in accordance with the procedures
prescribed by these Bylaws, and if the chairman should so determine, the
chairman shall so declare at the meeting and the defective nomination shall be
disregarded.

     At an annual meeting of the stockholders, only such business shall be
conducted as shall have been properly brought before the meeting. To be properly
brought before an annual meeting, business must be: (a) as specified in the
notice of meeting (or any supplement thereto) given by or at the direction of
the Board of Directors, (b) otherwise properly brought before the meeting by or
at the direction of the Board of Directors, or (c) otherwise properly brought
before the meeting by a stockholder that was a stockholder of record at the time
of the giving of the relevant notice as provided below. Business to be brought
before an annual meeting by a stockholder shall not be considered properly
brought if the stockholder has not given timely notice thereof in writing to the
Secretary of the corporation or if such business is not a proper matter for
stockholder action under the General Corporation Law of the State of Delaware.
To be timely, a stockholder's notice must be delivered to or mailed and received
at the principal executive offices of the corporation not less than sixty (60)
nor more than one hundred twenty (120) days prior to the scheduled meeting
regardless of any postponements, deferrals or adjournments of that meeting to a
later date; provided, however, that in the event that less than seventy (70)
days notice or prior public disclosure of the date of the meeting is given or
made to stockholders, notice by the stockholder to be timely must be so received
not later than the close of business on the tenth day following the day on which
such notice of the date of the annual meeting was mailed or such public
disclosure was made. A stockholder's notice to the Secretary shall set forth as
to each matter the stockholder proposes to bring before the annual meeting: (i)
a brief description of the business desired to be brought before the annual
meeting and the reasons for conducting such business at the annual meeting, (ii)
the name and address, as they appear on the corporation's books, of the
stockholder proposing such business and any other stockholders known by such
stockholder to be supporting such proposal, (iii) the class and number of shares
of the corporation which are beneficially owned by the stockholder and by any
other stockholders known by such stockholder to be supporting such proposal on
the date of such stockholder notice, (iv) any material interest of the
stockholder in such business, and (v) any other information that is required by
law to be provided by the stockholder in his capacity as a proponent of a
stockholder proposal. Notwithstanding the foregoing, in order to include
information with respect to a stockholder proposal in the proxy statement and
form of proxy for a stockholders' meeting, stockholders must provide notice as
required by the regulations promulgated under the

                                      -3-
<PAGE>

Securities Exchange Act of 1934, as amended. Notwithstanding anything in these
bylaws to the contrary, no business shall be conducted at any annual meeting
except in accordance with the procedures set forth in this Section. The chairman
of the annual meeting shall, if the facts warrant, determine and declare at the
meeting that business was not properly brought before the meeting and in
accordance with the provisions of this Section, and, if the chairman should so
determine, the chairman shall so declare at the meeting that any such business
not properly brought before the meeting shall not be transacted.

     2.6  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE
          --------------------------------------------

     Written notice of any meeting of stockholders shall be given either
personally or by first-class mail or by telegraphic or other written
communication. Notices not personally delivered shall be sent charges prepaid
and shall be addressed to the stockholder at the address of that stockholder
appearing on the books of the corporation or given by the stockholder to the
corporation for the purpose of notice. Notice shall be deemed to have been given
at the time when delivered personally or deposited in the mail or sent by
telegram or other means of written communication.

     An affidavit of the mailing or other means of giving any notice of any
stockholders' meeting, executed by the secretary, assistant secretary or any
transfer agent of the corporation giving the notice, shall be prima facie
evidence of the giving of such notice.

     2.7  QUORUM
          ------

     The holders of a majority in voting power of the stock issued and
outstanding and entitled to vote thereat, present in person or represented by
proxy, shall constitute a quorum at all meetings of the stockholders for the
transaction of business except as otherwise provided by statute or by the
certificate of incorporation. If, however, such quorum is not present or
represented at any meeting of the stockholders, then either (i) the chairman of
the meeting or (ii) the stockholders entitled to vote thereat, present in person
or represented by proxy, shall have power to adjourn the meeting in accordance
with Section 2.7 of these bylaws.

     When a quorum is present at any meeting, the vote of the holders of a
majority of the stock having voting power present in person or represented by
proxy shall decide any question brought before such meeting, unless the question
is one upon which, by express provision of the laws of the State of Delaware or
of the certificate of incorporation or these bylaws, a different vote is
required, in which case such express provision shall govern and control the
decision of the question.

     If a quorum be initially present, the stockholders may continue to transact
business until adjournment, notwithstanding the withdrawal of enough
stockholders to leave less than a quorum, if any action taken is approved by a
majority of the stockholders initially constituting the quorum.

                                      -4-
<PAGE>

     2.8  ADJOURNED MEETING; NOTICE
          -------------------------

     When a meeting is adjourned to another time and place, unless these bylaws
otherwise require, notice need not be given of the adjourned meeting if the time
and place thereof are announced at the meeting at which the adjournment is
taken. At the adjourned meeting the corporation may transact any business that
might have been transacted at the original meeting. If the adjournment is for
more than 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.

     2.9  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 the State of Delaware (relating to voting rights of fiduciaries, pledgors and
joint owners, and to voting trusts and other voting agreements).

     Except as may be otherwise provided in the certificate of incorporation or
these bylaws, each stockholder shall be entitled to one vote for each share of
capital stock held by such stockholder.

     At a stockholders' meeting at which directors are to be elected, a
stockholder shall be entitled to cumulate votes (i.e., cast for any candidate a
number of votes greater than the number of votes which such stockholder normally
is entitled to cast) if the candidates' names have been placed in nomination
prior to commencement of the voting and the stockholder has given notice prior
to commencement of the voting of the stockholders' intention to cumulate votes.
If any stockholder has given such a notice, then every stockholder entitled to
vote may cumulate votes for candidates in nomination either (i) by giving one
candidate a number of votes equal to the number of directors to be elected
multiplied by the number of votes to which that stockholder's shares are
normally entitled or (ii) by distributing the stockholder's votes on the same
principle among any or all of the candidates, as the stockholder thinks fit. The

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

     Whenever notice is required to be given under any provision of the General
Corporation Law of the State 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

                                      -5-
<PAGE>

notice of such meeting, except when the person attends a meeting for the express
purpose of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice unless so
required by the certificate of incorporation or these bylaws.

     2.11  STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING
           -------------------------------------------------------

     Unless otherwise provided in the certificate of incorporation, any action
required by this chapter to be taken at any annual or special meeting of
stockholders of a corporation, or any action that may be taken at any annual or
special meeting of such stockholders, may be taken without a meeting, without
prior notice, and without a vote if a consent in writing, setting forth the
action so taken, is signed by the holders of outstanding stock having not less
than the minimum number of votes that would be necessary to authorize or take
such action at a meeting at which all shares entitled to vote thereon were
present and voted.

     Prompt notice of the taking of the corporate action without a meeting by
less than unanimous written consent shall be given to those stockholders who
have not consented in writing and, who, if the action had been taken at a
meeting, would have been entitled to notice of the meeting if the record date
for such meeting had been the date that written consents signed by a sufficient
number of holders to take the action were delivered to the corporation as
provided in Section 228(c) of the General Corporation Law of the State of
Delaware. If the action which is consented to is such as would have required the
filing of a certificate under any section of the General Corporation Law of the
State of Delaware if such action had been voted on by stockholders at a meeting
thereof, then the certificate filed under such section shall state, in lieu of
any statement required by such section concerning any vote of stockholders, that
written notice and written consent have been given as provided in Section 228 of
the General Corporation Law of the State of Delaware.

     Notwithstanding the foregoing, effective upon the closing of a firm
commitment underwritten public offering of Common Stock of the corporation, no
action that is required or permitted to be taken by the stockholders at any
annual or special meeting of stockholders may be effected by written consent of
stockholders in lieu of a meeting of stockholders.

     2.12  RECORD DATE FOR STOCKHOLDER NOTICE; VOTING
           ------------------------------------------

     For purposes of determining the stockholders entitled to notice of any
meeting or to vote thereat, the Board of Directors may fix, in advance, a record
date, which shall not precede the date upon which the resolution fixing the
record date is adopted by the Board of Directors and which shall not be more
than sixty (60) days nor less than ten (10) days before the date of any such
meeting, and in such event only stockholders of record on the date so fixed are
entitled to notice and to vote, notwithstanding any transfer of any shares on
the books of the corporation after the record date.

                                      -6-
<PAGE>

     If the Board of Directors does not so fix a record date, the record date
for determining stockholders entitled to notice of or to vote at a meeting of
stockholders shall be at the close of business on the business day next
preceding the day on which notice is given, or, if notice is waived, at the
close of business on the business day next preceding the day on which the
meeting is held.

     A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting
unless the Board of Directors fixes a new record date for the adjourned meeting,
but the Board of Directors shall fix a new record date if the meeting is
adjourned for more than thirty (30) days from the date set for the original
meeting.

     The record date for any other purpose shall be as provided in Section 8.1
of these bylaws.

     Every person entitled to vote for directors, or on any other matter, shall

a written proxy signed by the person 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, telefacsimile or
otherwise) by the stockholder or the stockholder's attorney-in-fact. The
revocability of a proxy that states on its face that it is irrevocable shall be
governed by the provisions of Section 212(e) of the General Corporation Law of
the State of Delaware.

     2.14  LIST OF STOCKHOLDERS ENTITLED TO VOTE
           -------------------------------------

     The officer who has charge of the stock ledger of the corporation shall
prepare and make, at least ten (10) days before every meeting of stockholders, a
complete list of the stockholders entitled to vote at the meeting, arranged in
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.

in which such person was or is a party or is threatened to be made a party by
reason of the fact that such person is or was an employee or agent of the
corporation. For purposes of this Section 6.2, an "employee" or "agent" of the
corporation (other than a director or officer) shall mean any person (i) who is
or was an employee or agent of the corporation, (ii) who is or was serving at
the request of the corporation as an employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, or (iii) who was an
employee or agent of a corporation which was a predecessor corporation of the
corporation or of another enterprise at the request of such predecessor
corporation.

     6.3  INSURANCE
          ---------

     The corporation may purchase and maintain insurance on behalf of any person
who is or was a director, officer, employee or agent of the corporation, or is
or was serving at the request of the corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise against any liability asserted against such person and incurred
by such person in any such capacity, or arising out of such person's status as
such, whether or not the corporation would have the power to indemnify such
person against such liability under the provisions of the General Corporation
Law of the State of Delaware.

                                  ARTICLE VII

                              RECORDS AND REPORTS
                              -------------------

     7.1  MAINTENANCE AND INSPECTION OF RECORDS
          -------------------------------------

     The corporation shall, either at its principal executive office or at such
place or places as designated by the Board of Directors, keep a record of its
stockholders listing their names and addresses and the number and class of
shares held by each stockholder, a copy of these bylaws as amended to date,
accounting books and other records of its business and properties.

     Any stockholder of record, in person or by attorney or other agent, shall,
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

                                      -16-
<PAGE>

to so act on behalf of the stockholder. The demand under oath shall be directed
to the corporation at its registered office in the State of Delaware or at its
principal place of business.

     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 or her position as a director.

     7.3  ANNUAL STATEMENT TO STOCKHOLDERS
          --------------------------------

     The Board of Directors shall present at each annual meeting, and at any
special meeting of the stockholders when called for by vote of the stockholders,
a full and clear statement of the business and condition of the corporation.

     7.4  REPRESENTATION OF SHARES OF OTHER CORPORATIONS
          ----------------------------------------------

     The chairman of the board, if any, the president, any vice president, the
chief financial officer, the secretary or any 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 the
stock of any other corporation or corporations standing in the name of this
corporation. The authority herein granted may be exercised either by such person
directly or by any other person authorized to do so by proxy or power of
attorney duly executed by such person having the authority.

     7.5  CERTIFICATION AND INSPECTION OF BYLAWS
          --------------------------------------

     The original or a copy of these bylaws, as amended or otherwise altered to
date, certified by the secretary, shall be kept at the corporation's principal
executive office and shall be open to inspection by the stockholders of the
corporation, at all reasonable times during office hours.

                                 ARTICLE VIII

                                GENERAL MATTERS
                                ---------------

     8.1  RECORD DATE FOR PURPOSES OTHER THAN NOTICE AND VOTING
          -----------------------------------------------------

     For purposes of determining the stockholders entitled to receive payment of
any dividend or other distribution or allotment of any rights or the
stockholders entitled to exercise any rights in respect of any other lawful
action, the Board of Directors may fix, in advance, a record date, which record
date shall not precede the date upon which the resolution fixing the record date
is adopted and which shall not be more than sixty (60) days before any such
action. In that case, only stockholders of record at the close of business on
the date so fixed are entitled to receive the dividend, distribution or
allotment of rights, or to exercise such rights, as the case may be,
notwithstanding any transfer of

                                      -17-
<PAGE>

any shares on the books of the corporation after the record date so fixed,
except as otherwise provided in the General Corporation Law of the State of
Delaware. If no record date is fixed, the record date for determining
stockholders for any such purpose shall be at the close of business on the day
on which the Board of Directors adopts the resolution relating thereto.

     If the Board of Directors does not so fix a record date, then the record
date for determining stockholders for any such purpose shall be at the close of
business on the day on which the Board of Directors adopts the applicable
resolution.

     8.2  CHECKS; DRAFTS; EVIDENCES OF INDEBTEDNESS
          -----------------------------------------

     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.

     8.3  CORPORATE CONTRACTS AND INSTRUMENTS:  HOW EXECUTED
          --------------------------------------------------

     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.

     8.4  STOCK CERTIFICATES; TRANSFER; PARTLY PAID SHARES
          ------------------------------------------------

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

                                      -18-
<PAGE>

     Upon surrender to the secretary or transfer agent of the corporation of a
certificate for shares duly endorsed or accompanied by proper evidence of
succession, assignment or authority to transfer, it shall be the duty of the
corporation to issue a new certificate to the person entitled thereto, cancel
the old certificate and record the transaction upon its books.

     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, or 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.

     8.5  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
the State 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.

     8.6  LOST CERTIFICATES
          -----------------

     Except as provided in this Section 8.6, 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 Board of
Directors may, in case any share certificate or certificate for any other
security is lost, stolen or destroyed, authorize the issuance of replacement
certificates or uncertificated shares on such terms and conditions as the board
may require; the board may require indemnification of the corporation secured by
a bond or other adequate security sufficient to protect the corporation against
any claim that may be made against it, including any expense or liability, on
account of the alleged loss, theft or destruction of the certificate or the
issuance of the replacement certificate or uncertificated shares.

     8.7  CONSTRUCTION; DEFINITIONS
          -------------------------

     Unless the context requires otherwise, the general provisions, rules of
construction, and definitions in the General Corporation Law of the State of
Delaware shall govern the construction of these bylaws. Without limiting the
generality of this provision, the singular number includes the plural, the
plural number includes the singular, and the term "person" includes both a
corporation and a natural person.

                                  ARTICLE IX

                                  ----------

     9.1  AMENDMENTS BY STOCKHOLDERS AND DIRECTORS
          ----------------------------------------

     The original or other bylaws of the corporation may be adopted, amended or
repealed by the stockholders entitled to vote or by the Board of Directors of
the corporation. 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.

     Whenever an amendment or new bylaw is adopted, it shall be copied in the
book of bylaws with the original bylaws, in the appropriate place. If any bylaw
is repealed, the fact of repeal with the date of the meeting at which the repeal
was enacted or the filing of the operative written consent(s) shall be stated in
said book.

    1.2  Requested Registration.
         ----------------------

         (a)  Request for Registration.  In case the Company shall receive from
              ------------------------
Initiating Holders a written request that the Company file a registration
statement under the 1933 Act with respect to shares of Registrable Securities
whose expected aggregate offering price is not less than: (i) $10,000,000 if
such request is made prior to the Company's Initial Public Offering, or (ii)
$7,500,000 of such request is made after the Company's Initial Public Offering,
the Company will:

             (i)  promptly, and in no event later than 30 days from receipt of
such written request, give written notice of such request to all other Holders;
and

             (ii) subject to the limitations of Section 1.2(b) below, as soon as
practicable, use its best efforts to effect such registration under the 1933 Act
(including, without limitation, appropriate qualification under applicable blue
sky or other state securities laws and appropriate compliance with applicable
regulations issued under the 1933 Act and any other governmental requirements or
regulations) 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 received by the Company within 20 days after receipt of such
written notice from the Company; provided that the Company shall not be
obligated to take any action to effect any such registration, qualification or
compliance pursuant to this Section 1.2:

                 (A)  Prior to the third anniversary of the closing date of the
initial purchase and sale of the Series D Preferred;

                 (B)  During the period starting with the date of filing of any
registration statement in connection with the Initial Public Offering, provided
that the Company is actively employing in good faith all reasonable efforts to
cause such registration statement to become effective, and ending on the date
which is 180 days after the date on which such registration statement is
declared effective;

                 (C)  If the Company has previously effected two (2)
registrations under this Section 1.2;

                                      -3-
<PAGE>

                 (D)  If the Company delivers notices to the Holders not more
than 30 days after receipt of any registration request of the Initiating Holders
that it intends to file a registration statement for its Initial Public Offering
within 90 days of the receipt of such registration request; or

                 (E)  If the Company shall furnish to the Holders requesting a
registration statement pursuant to this Section 1.2 a certificate, signed by the
Chairman of the Board 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 or
effected at such time, in which event the Company shall have the right to defer
such filing for a period of not more than 90 days after receipt of the
registration request of the Initiating Holders; provided that such right to
delay a request shall be exercised by the Company not more than once in any 12
month period.

         Subject to the foregoing clauses (A) through (E) inclusive, 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 and in any event within 120 days
after receipt of such request.

         (b)  Underwriting. In the event that a registration pursuant to this
              ------------
Section 1.2 is for a registered Public Offering by means of an underwriting, the
Company shall so advise the Holders as part of the notice given pursuant to
Section 1.2(a)(i) above. In such event, the right of any Holder to registration
pursuant to this Section 1.2 shall be conditioned upon such Holder's
participation in the underwriting arrangements required by this Section 1.2(b),
and the inclusion of such Holder's Registrable Securities in the underwriting to
the extent requested shall be limited to the extent provided herein.

         The Company shall (together with all Holders proposing to distribute
their securities through such underwriting) enter into an underwriting agreement
in customary form with a managing underwriter or underwriters selected for such
underwriting by a majority in interest of the Initiating Holders (which
underwriter or underwriters shall be reasonably acceptable to the Company).
Notwithstanding any other provision of this Section 1.2, if the managing
underwriter advises the Initiating Holders in writing that marketing factors
require a limitation of the number of shares to be underwritten, then the
Company shall so advise all Holders of Registrable Securities which would
otherwise be underwritten pursuant hereto, and the number of shares of
Registrable Securities that may be included in the registration and underwriting
shall be allocated among all Holders thereof in proportion, as nearly as
practicable, to the respective amounts of Registrable Securities held by such
Holders at the time of filing the registration statement, provided, however,
that the number of shares of Registrable Securities to be included in such
underwriting and registration shall not be reduced unless all other securities
of the Company are first entirely excluded from the underwriting and
registration.  No Registrable Securities excluded from the underwriting by
reason of the underwriter's marketing limitation shall be included in such
registration.  To facilitate the allocation of shares in accordance with the
above provisions, the Company or the underwriters may round the number of shares
allocated to any Holder to the nearest 100 shares.

                                      -4-
<PAGE>

         If any Holder of Registrable Securities disapproves of the terms of
the underwriting, such person may elect to withdraw therefrom by written notice
to the Company, the managing underwriter and the Initiating Holders.  The
Registrable Securities and/or other securities held by such Holder affected
shall be withdrawn from registration.  If the registration does not become
effective due to the withdrawal of Registrable Securities, then either: (a) the
Holders requesting registration shall reimburse the Company for expenses
incurred in complying with the request, or (b) the aborted registration shall be
treated as effected for purposes of Section 1.2(a)(ii)(C); provided, however,
that if at the time of such withdrawal, the Holder or Holders have learned of a
material adverse change in the condition, business, or prospects of the Company
from that known to the Holders at the time of their request and have withdrawn
the request with reasonable promptness following disclosure by the Company of
such material adverse change, then the Holders shall not be required to pay any
of such expenses, and the aborted registration shall not be treated as effected
for purposes of Section 1.2(a)(ii)(C).

    1.3  Piggy-back Registration Rights.
         ------------------------------

         (a)  Piggy-back Rights. Except with respect to the Company's Initial
              -----------------
Public Offering, if (but without any obligation to do so) the Company proposes
to register (including for this purpose a registration effected by the Company
for shareholders other than the Holders) any of its securities in connection
with a Public Offering, other than (i) a registration relating solely to
employee benefit plans, or (ii) a registration relating solely to a Commission
Rule 145 transaction, the Company shall promptly give each Holder written notice
of such registration, together with a list of the jurisdictions in which the
Company intends to attempt to qualify such securities under applicable state
securities laws. Upon the written request of each Holder given within 15 days
after delivery of such written notice by the Company in accordance with Section
5.3 below, the Company shall, subject to the provisions of Section 1.3(b) below,
use its best efforts to cause to be registered under the 1933 Act all of the
Registrable Securities that each such Holder has requested to be registered. If
a Holder decides not to include all of its Registrable Securities in any
registration statement thereafter filed by the Company, such Holder shall
nevertheless continue to have the right to include any of its Registrable
Securities in any subsequent registration statement or statements as may be
filed by the Company with respect to offerings of its securities, all upon the
terms and conditions set forth herein.

         (b)  Underwriting Requirements in Piggy-back Registration. If the
registration statement under which the Company gives notice under this Section
1.3 is for an underwritten offering, the Company shall so advise the Holders of
Registrable Securities. The right of any Holder to registration pursuant to
Section 1.3(a) above 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 (each, a "Participating
Holder") shall (together with the Company and any other holders of Company
securities distributing their securities through such underwriting) enter into
an underwriting agreement in customary form with the underwriter or underwriters
selected for underwriting by the Company. Notwithstanding any other provision of
this Section 1.3, if the underwriter determines that marketing factors require a
limitation of the number of shares to be

                                      -5-
<PAGE>

underwritten, the underwriter may (subject to the allocation priority set forth
below) exclude some or all Registrable Securities from such registration and
underwriting. Further, notwithstanding anything to the contrary herein, no
reduction shall be made with respect to securities offered by the Company for
its own account under this Section 1.3. The Company shall so advise all persons
requesting registration, and the number of shares of securities that may be
included in the registration and underwriting shall be allocated in the
following manner. The number of shares that may be included in the registration
and underwriting shall be allocated (i) first to the Company; (ii) second to the
Participating Holders, in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities held by such Holders; and (iii)
third, to any other shareholders of the Company (other than Participating
Holders) on a pro rata basis. In no event shall the amount of securities of the
selling Holders included in the registration be reduced below twenty-five
percent (25%) of the total amount of securities included in such registration,
unless such offering is the Initial Public Offering and such registration does
not include shares of any other selling shareholders, in which event any or all
of the Registrable Securities of the Holders may be excluded in accordance with
the immediately preceding sentence. In no event will shares of any other
participating shareholder be included in such registration which would reduce
the number of shares which may be included by Participating Holders without the
written consent of Participating Holders of not less than a majority of the
Registrable Securities proposed to be sold in the offering. If any Holder
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. In no event will the Company have any
obligation under this Section 1.3 with respect to its Initial Public Offering.

    1.4  Form S-3 Registration.  In case the Company shall receive from any
         ---------------------
Holder or Holders a written request or requests that the Company effect a
registration on Form S-3 and any related qualification or compliance with
respect to all or a part of the Registrable Securities owned by such Holder or
Holders, the Company will:

         (a)  promptly give written notice of the proposed registration, and any
related qualification or compliance, to all other Holders; and

         (b)  as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of such Holder's or
Holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any other Holder or Holders
joining in such request as are specified in a written request given within 15
days after receipt of such written notice from the Company; provided that the
Company shall not be obligated to effect any such registration, qualification or
compliance, pursuant to this Section 1.4: (i) if the Company is not qualified as
a registrant entitled to use Form S-3; (ii) if the Holders, together with the
holders of any other securities of the Company entitled to inclusion in such
registration, propose to sell Registrable Securities and such other securities
(if any) at an aggregate price to the public of less than $500,000; (iii) if the
Company shall furnish to the 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

                                      -6-
<PAGE>

seriously detrimental to the Company and its shareholders for such Form S-3
registration to be effected at such time, in which event the Company shall have
the right to defer the filing of the Form S-3 registration statement for a
period of not more than 120 days after receipt of the request of the Holder or
Holders under this Section 1.4; provided that the Company shall not utilize this
right more than once in the prior twelve (12) month period; or (iv) if the
Company has already effected one (1) registration on Form S-3 for the Holders
pursuant to this Section 1.4 in the prior twelve (12) month period.

    1.5  Obligations of the Company.  Whenever required under this Section 1 to
         --------------------------
effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

         (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the Holders
of a majority of the Registrable Securities registered thereunder, keep such
registration statement effective for up to 120 days.

         (b)  Prepare and file with the SEC such amendments and supplements to
such registration statement and the prospectus used in connection with such
registration statement as may be necessary to comply with the provisions of the
1933 Act with respect to the disposition of all securities covered by such
registration statement.

         (c)  Furnish to the Holders such numbers of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
1933 Act, and such other documents as they may reasonably request in order to
facilitate the disposition of Registrable Securities owned by them.

         (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under the securities laws of such
jurisdictions as shall be reasonably appropriate for the distribution of the
securities covered by the registration statement, provided that the Company
shall not be required in connection therewith or as a condition thereto to
qualify to do business or to file a general consent to service of process in any
such jurisdiction, and provided further that (anything in this Agreement to the
contrary notwithstanding with respect to the bearing of expenses) if any
jurisdiction in which the securities shall be qualified shall require that
expenses incurred in connection with the qualification of the securities in that
jurisdiction be borne by selling shareholders, then such expenses shall be
payable by the selling Holders pro rata, to the extent required by such
jurisdiction if such Holders do not elect to withdraw from the registration
after notice of such requirement.

         (e)  In the event of any underwritten Public Offering, enter into and
perform its obligations under an underwriting agreement with terms generally
satisfactory to the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

                                      -7-
<PAGE>

         (f)  Notify each Holder of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the 1933 Act of the happening of any event as a
result of which the prospectus included in such registration statement, as then
in effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing.

         (g)  Furnish, at the request of a majority of the Holders participating
in the registration, on the date that such Registrable Securities are delivered
to the underwriters for sale, if such securities are being sold through
underwriters, or, if such securities are not being sold through underwriters, on
the date that the registration statement with respect to such securities becomes
effective, (i) an opinion, dated as of such date, of the counsel representing
the Company for the purposes of such registration, in form and substance as is
customarily given to underwriters in an underwritten public offering and
reasonably satisfactory to a majority in interest of the Holders requesting
registration, addressed to the underwriters, if any, and to the Holders
requesting registration of Registrable Securities and (ii) a letter dated as of
such date, from the independent certified public accountants of the Company, in
form and substance as is customarily given by independent certified public
accountants to underwriters in an underwritten public offering and reasonably
satisfactory to a majority in interest of the Holders requesting registration,
addressed to the underwriters, if any, and if permitted by applicable accounting
standards, to the Holders requesting registration of Registrable Securities.

    1.6  Furnish Information.  In connection with any action pursuant to this
         -------------------
Section 1, the selling Holders shall furnish to the Company such information
regarding themselves, the Registrable Securities held by them, and the intended
method of disposition of such securities as shall be required to effect the
registration of their Registrable Securities. In that connection, each selling
Holder shall be required to represent to the Company that all such information
which is given is both complete and accurate in all material respects when made.

    1.7  Expenses of Registration.  All Registration Expenses shall be borne by
         ------------------------
the Company. All Selling Expenses shall be borne by the Holders of the
securities so registered, (i) in an underwritten transaction, pro rata, on the
basis of the number of shares so registered or (ii) otherwise, by the Holder or
Holders who incurred such expenses.

    1.8  Delay of Registration.  No Holder shall have any right to obtain or
         ---------------------
seek an injunction restraining or otherwise delaying any registration as the
result of any controversy that might arise with respect to the interpretation or
implementation of this Section 1.

    1.9  Indemnification.  In the event any Registrable Securities are included
         ---------------
in a registration statement under this Section 1:

         (a)  To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, the officers, directors, partners, and members (if
Holder is an LLC) of each Holder, any underwriter (as defined in the 1933 Act)
for such Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the 1933 Act or the 1934 Act, against any

                                      -8-
<PAGE>

losses, claims, damages, or liabilities (joint or several) to which they may
become subject under the 1933 Act, the 1934 Act or other federal or state law,
insofar as such losses, claims, damages, or liabilities (or actions in respect
thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation"): (i) any untrue statement
or alleged untrue statement of a material fact contained in such registration
statement, including any preliminary prospectus or final prospectus contained
therein or any amendments or supplements thereto; (ii) the omission or alleged
omission to state therein a material fact required to be stated therein, or
necessary to make the statements therein not misleading; or (iii) any violation
or alleged violation by the Company of the 1933 Act, the 1934 Act, any state
securities law or any rule or regulation promulgated under the 1933 Act, the
1934 Act or any state securities law; and the Company will reimburse each such
Holder, officer, director or partner, underwriter or controlling person for any
legal or other expenses reasonably incurred by them in connection with
investigating or defending any such loss, claim, damage, liability, or action.
The Company's indemnity contained in this Section 1.9(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable to any
Holder in any such case for any such loss, claim, damage, liability, or action
to the extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished in writing
and expressly stated for use in connection with such registration by any such
Holder. The Company shall not be required to indemnify any person against any
liability arising from any untrue or misleading statement or omission contained
in any preliminary prospectus if such deficiency is corrected in the final
prospectus or any amendments or supplements thereto (collectively, the "Final
Prospectus"), and after the Company has furnished such Holder with a copy of the
Final Prospectus, such Holder fails to deliver a copy of such Final Prospectus.
The indemnity provided for in this Section 1.9(a) shall remain in full force and
effect regardless of any investigation made by or on behalf of such seller,
underwriter, participating person or controlling person and shall survive
transfer of such securities by such seller.

         (b)  To the extent permitted by law, each selling Holder will indemnify
and hold harmless the Company, each of its directors, each of its officers who
have signed the registration statement, each person, if any, who controls the
Company within the meaning of the 1933 Act, any underwriter (within the meaning
of the 1933 Act) for the Company, any person who controls such underwriter, and
any other Holder selling securities in such registration statement or any of its
partners, directors or officers or any person who controls such Holder, against
any losses, claims, damages or liabilities (joint or several) to which any of
the foregoing persons may become subject, under the 1933 Act, the 1934 Act or
other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereto) arise out of or are based upon any
Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder and expressly stated in a writing for use in connection
with such registration; and each such Holder will reimburse any legal or other
expenses, as reasonably incurred, by any person intended to be indemnified
pursuant to this Section 1.9(b), in connection with investigating or defending
any such loss, claim, damage, liability, or action. The indemnity agreement
contained in this Section 1.9(b) shall not apply to amounts paid in settlement
of any such loss, claim, damage, liability or action if such settlement is
effected

                                      -9-
<PAGE>

without the consent of the Holder, which consent shall not be unreasonably
withheld, provided, that in no event shall any indemnity under this Section
1.9(b) exceed the net proceeds from the offering received by such Holder, except
in the case of willful fraud by such Holder.

         (c)  Promptly after receipt by an indemnified party under this Section
1.9 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 1.9, notify the
indemnifying party in writing of the commencement thereof and the indemnifying
party shall have the right to participate in, and, to the extent the
indemnifying party so desires, jointly with any other indemnifying party
similarly noticed, to assume the defense thereof with counsel mutually
satisfactory to the parties; provided that an indemnified party shall have the
                             -------------
right to retain its own counsel, with the reasonable fees and expenses to be
paid by the indemnifying party if the indemnified party reasonably determines
that representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to notify an indemnifying party within a
reasonable time of the commencement of any such action, to the extent
prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.9, but the omission so to notify the indemnifying party will not relieve it of
any liability that it may have to any indemnified party otherwise than under
this Section 1.9.

         (d)  Notwithstanding the foregoing, to the extent that the provisions
on indemnification and contribution contained in the underwriting agreement
entered into in connection with the underwritten public offering are in conflict
with the foregoing provisions, the provisions in the underwriting agreement
shall control, provided, however, that the failure of the underwriting agreement
to address an issue shall not be deemed to be a conflict between the
underwriting agreement and this Agreement.

         (e) The obligations of the Company and Holders under this Section 1.9
shall survive the completion of any offering of the Registrable Securities in a
registration statement under this Section 1.

    1.10 Reports Under Securities Exchange Act of 1934.  With a view of making
         ---------------------------------------------
available to the Holders the benefits of Rule 144 promulgated under the 1933 Act
and any other rule or regulation of the SEC that may at any time permit a Holder
to sell securities of the Company to the public without registration, the
Company agrees to:

         (a)  use its best efforts to make and keep public information
available, as those terms are understood and defined in SEC Rule 144, at all
times after 90 days after the effective date of the registration statement filed
by the Company in connection with its Initial Public Offering;

         (b)  take such action, including the voluntary registration of its
Common Stock under Section 12 of the 1934 Act, as is necessary to enable the
Holders to utilize Form S-3 for the sale of their Registrable Securities, such
action to be taken as soon as practicable after the end of the fiscal year in
which the registration of the Company's Initial Public Offering is declared
effective;

                                      -10-
<PAGE>

         (c)  use its best efforts to file with the SEC in a timely manner all
reports and other documents required of the Company under the 1933 Act and the
1934 Act; and

         (d)  furnish to any Holder, so long as the Holder owns any Registrable
Securities, upon reasonable request: (i) a written statement by the Company that
it has complied with the reporting requirements of SEC Rule 144 (at any time
after 90 days after the effective date of the registration statement filed by
the Company in connection with its Initial Public Offering), the 1933 Act and
the 1934 Act (at any time after it has become subject to such reporting
requirements), or that it qualifies as a registrant whose securities may be
resold pursuant to Form S-3 (at any time after it so qualifies); (ii) a copy of
the most recent annual or quarterly report of the Company and such other reports
and documents so filed by the Company; and (iii) such other information as may
be reasonably requested in availing any Holder of any rule or regulation of the
SEC or any state securities authorities which permits the selling of any such
securities without registration or pursuant to such form S-3.

    1.11 Assignment of Registration Rights.  The rights to cause the Company to
         ---------------------------------
register Registrable Securities pursuant to this Section 1 may be assigned by a
Holder to (A) a transferee or assignee of Registrable Securities who acquires
not less than 50,000 shares of the Registrable Securities (as adjusted for
recapitalizations, stock splits and combinations and the like), (B) a
subsidiary, parent, general partner, limited partner, retired partner,
affiliate, member (if Holder is an LLC) of a Holder, or investment fund or
entity controlled by a Holder, or (C) a Holder's family member or trust for the
benefit of an individual Holder or any family member; provided that (i) the
Company is, within a reasonable time after such transfer, furnished with written
notice of the name and address of such transferee or assignee and the securities
with respect to which such registration rights are being assigned, and (ii) such
assignment shall be effective only if immediately following such transfer the
transferee is bound by the terms and conditions of this Agreement and such
transfer of any Registrable Securities is lawful under all applicable securities
laws.

    1.12 Limitations on Subsequent Registration Rights.  From and after the date
         ---------------------------------------------
of this Agreement, the Company shall not, without the prior written consent of
the Holders of at least a majority of the Registrable Securities then
outstanding, enter into any agreement with any holder or prospective holder of
any securities of the Company which would: (i) permit such holder or prospective
holder to include such securities in any registration filed pursuant to Section
1.2, 1.3, or 1.4 above if such inclusion would adversely affect the rights of
any Holder of Registrable Securities hereunder (provided that the pro rata
participation of those additional shares in a registration or cutback shall not
be deemed an adverse affect if such pro rata participation is approved
unanimously by the Board of Directors); (ii) permit such holder or prospective
holder to require the Company to initiate any registration of any securities of
the Company; or (iii) grant such holder registration rights senior to those
granted to the Holders hereunder.

    1.13 Market Stand-off Agreement.  Each Holder agrees, in connection with the
         --------------------------
Company's Initial Public Offering, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any securities of the Company (other than those included in

                                      -11-
<PAGE>

the registration) without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time (not to exceed 180
days) from the effective date of such registration as may be requested by the
underwriters.

     In order to enforce the foregoing covenant, the Company may impose stop-
transfer instructions with respect to the Registrable Securities of each Holder
(and the shares or securities of every other person subject to the foregoing
restriction) until the end of such period.

    1.14 Termination of Registration Rights.  The registration rights granted
         ----------------------------------
pursuant to this Agreement shall terminate (i) as to all Holders on the date
which is the fifth year anniversary following the consummation of the Initial
Public Offering of the Company, or (ii) as to any Holder, at such time as such
Holder is able to sell all Registrable Securities held by it pursuant to Rule
144 promulgated under the 1933 Act in a three (3) month period.

2.  Rights of First Refusal.  The Company hereby grants to each Investor, as
    -----------------------
long as the Investor holds at least 1,500,000 shares of Registrable Securities
(as adjusted for recapitalizations, stock splits and combinations and the like),
the right of first refusal to purchase, pro rata, a portion of any New
Securities (as defined in Section 2.1 below) that the Company, from time to
time, may propose to sell and issue. Each Investor's pro rata share of the New
Securities will be the ratio of (i) the number of shares of Common Stock issued
and held, and issuable upon the conversion of the shares of Preferred Stock and
upon the exercise of the Warrants then held, by such Investor as of the date of
the Rights Notice (as defined below) to (ii) the total number of shares of
Common Stock issued and held, and issuable upon the conversion of the shares of
Preferred Stock and upon the exercise of the Warrants or any other options,
warrants or convertible securities then held, by all persons, or reserved for
issuance under stock option and stock purchase plans of the Company as of such
date. This right of first refusal will be subject to the following provisions:

    2.1  "New Securities" will mean any shares of Common Stock or Preferred
Stock of any kind of the Company, whether now or hereafter authorized, and
rights, options, or warrants to purchase said Common Stock or Preferred Stock,
and securities of any type whatsoever that are, or may become, convertible into
said Common Stock or Preferred Stock; provided that "New Securities" will not
include: (i) securities issuable upon the conversion of or with respect to the
Series A Preferred, Series B Preferred, Series C Preferred or Series D
Preferred; (ii) securities issuable, upon the exercise of or with respect to the
Warrants to purchase shares of Series B Preferred issued and outstanding on
March 11, 1998; (iii) securities issuable, upon the exercise of or with respect
to the Warrants to purchase shares of Series C Preferred issued and outstanding
as of the date of the close of the Company's Series C Preferred issuance; (iv)
securities issuable, upon the exercise of or with respect to the Warrants to
purchase shares of Series D Preferred issued and outstanding as of the date of
the close of the Company's Series D Preferred issuance; (v) securities issued in
connection with the acquisition of another corporation by the Company by merger,
consolidation, purchase of substantially all of the assets, or other
reorganization as a result of which the Company owns more than fifty percent
(50%) of the voting power of such corporation; (vi) up to 4,735,000 shares of
the Company's Common Stock or related options (or such greater number of shares
as may be approved by a unanimous vote of the Board of Directors) issued
pursuant to any

                                      -12-

which the holders of a majority in interest of the Registrable Securities then
outstanding waive their rights of first refusal under this Section 2; (ix)

similar purchase financing arrangement approved by a unanimous vote of the
Company's Board of Directors.

    2.2  If the Company proposes to issue New Securities, it will give each
Investor that holds at least 1,500,000 shares of Registrable Securities (as
adjusted for recapitalizations, stock splits and combinations and the like)
written notice (the "Rights Notice") of the Company's intention to do so,
describing the New Securities, the price, and the general terms upon which the
Company proposes to issue them. Each such Investor will have 15 days from the
date of delivery of the Rights Notice to agree to purchase up to its pro rata
share of such New Securities (as determined above) for the price and upon the
general terms specified in the Rights Notice by giving written notice to the
Company setting forth the quantity of New Securities to be purchased.

    2.3  If not all of the Investors elect to purchase their pro rata share of
New Securities, then the Company shall promptly notify in writing the Investors
who do so elect and shall offer such Investors the right to acquire such
unsubscribed shares. Such Investors shall have 5 days after receipt of such
notice to notify the Company of its election to purchase all or a portion
thereof of the unsubscribed shares.

         -----------------
refusal hereunder, the closing of the purchase of the New Securities with
respect to which such right has been exercised shall take place within ninety
(90) calendar days after each Investor gives notice of such exercise, which
period of time shall be extended if necessary to comply with applicable laws and
regulations. Upon exercise of such right of first refusal, the Company and such
Investor shall be legally obligated to consummate the purchase contemplated
thereby and shall use their best efforts to secure any approvals required in
connection therewith.

    2.5  Lapse and Reinstatement of Right.  In the event an Investor fails to
         --------------------------------
exercise the right of first refusal provided in this Section 2.1 within said
fifteen (15) 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 sixty (60) days from the date
of said agreement) to sell the New Securities not elected to be purchased by
such Investor at the price and upon the terms no more favorable to the
purchasers of such securities than specified in the notice. In the event the
Company has not sold the New Securities described in the notice or entered into
an agreement to sell the New Securities within said ninety (90) day period (or
sold the New Securities in accordance with the foregoing within sixty (60) days
from the date of said agreement), the Company shall not thereafter issue or sell
any New Securities without first offering such securities to each Investor in
the manner provided above.

qualification or legend.

    4.3  Any legend endorsed on an instrument pursuant to applicable state
securities laws and the stop-transfer instructions with respect to such
securities shall be removed upon receipt by the Company of an order of the

                                 2BRIDGE, INC.

                           INDEMNIFICATION AGREEMENT



     This Indemnification Agreement ("Agreement") is made as of ______________
by and between 2Bridge, Inc., a Delaware corporation (which, together with the
California corporation which was its predecessor, is known herein as the
"Company"), and _______________ ("Indemnitee").

     WHEREAS, the Company and Indemnitee recognize the increasing difficulty in
obtaining directors' and officers' liability insurance, the significant
increases in the cost of such insurance and the general reductions in the
coverage of such insurance;

     WHEREAS, the Company and Indemnitee further recognize the substantial
increase in corporate litigation in general, subjecting officers and directors
to expensive litigation risks at the same time as the coverage of liability
insurance has been limited;

     WHEREAS, Indemnitee does not regard the current protection available as
adequate under the present circumstances, and Indemnitee and other officers and
directors of the Company may not be willing to continue to serve as officers and
directors without additional protection; and

     WHEREAS, the Company desires to attract and retain the services of highly
qualified individuals, such as Indemnitee, to serve as officers and directors of
the Company and to indemnify its officers and directors so as to provide them
with the maximum protection permitted by law.

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

     1.  Indemnification.
         ---------------

         (a) Third Party Proceedings.  The Company shall indemnify Indemnitee
              -----------------------
if Indemnitee is or was a party or is threatened to be made a party to any
threatened, pending or completed action or proceeding, whether civil, criminal,
administrative or investigative (other than an action by or in the right of the
Company) by reason of the fact that Indemnitee is or was a director, officer,
employee or agent of the Company, or any subsidiary of the Company, by reason of
any action or inaction on the part of Indemnitee while an officer or director or
by reason of the fact that Indemnitee is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other  enterprise, against expenses
(including attorneys' fees), judgments, fines and amounts paid in settlement (if
such settlement is approved in advance by the Company, which approval shall not
be unreasonably withheld) actually and reasonably incurred by Indemnitee in
connection with such action or proceeding if Indemnitee acted in good faith and
in a manner Indemnitee reasonably believed to be in or not opposed to the
<PAGE>

best interests of the Company, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe Indemnitee's conduct was
unlawful. The termination of any action, suit or proceeding by judgment, order,
settlement, conviction, or upon a plea of nolo contendere or its equivalent,
                                          ---- ----------
shall not, of itself, create a presumption that (i) Indemnitee did not act in
good faith, (ii) Indemnitee did not act in a manner which Indemnitee reasonably
believed to be in or not opposed to the best interests of the Company, or (iii)
with respect to any criminal action or proceeding, Indemnitee had no reasonable
cause to believe that Indemnitee's conduct was unlawful.

         (b) Proceedings By or in the Right of the Company.  The Company shall
             ---------------------------------------------
indemnify Indemnitee if Indemnitee was or is a party or is threatened to be made
a party to any threatened, pending or completed action or suit by or in the
right of the Company or any subsidiary of the Company to procure a judgment in
its favor by reason of the fact that Indemnitee is or was a director, officer,
employee or agent of the Company, or any subsidiary of the Company, by reason of
any action or inaction on the part of Indemnitee while an officer or director or
by reason of the fact that Indemnitee is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise, against expenses
(including attorneys' fees) and, to the fullest extent permitted by law, amounts
paid in settlement, in each case to the extent actually and reasonably incurred
by Indemnitee in connection with the defense or settlement of such action or
proceeding if Indemnitee acted in good faith and in a manner Indemnitee
reasonably believed to be in or not opposed to the best interests of the Company
and its stockholders, except that no indemnification shall be made in respect of
any claim, issue or matter as to which Indemnitee shall have been adjudged to be
liable to the Company in the performance of Indemnitee's duty to the Company and
its stockholders unless and only to the extent that the court in which such
action or suit is or was pending shall determine upon application that, in view
of all the circumstances of the case, Indemnitee is fairly and reasonably
entitled to indemnity for such expenses and then only to the extent that the
court shall determine.

     2.  Agreement to Serve.  In consideration of the protection afforded by
         ------------------
this Agreement, if Indemnitee is a director of the Company, he agrees to serve
at least for the balance of the current term as a director and not to resign
voluntarily during such period without the written consent of a  majority of the
Board of Directors.  If Indemnitee is an officer  of the Company not serving
under an employment contract, he agrees to serve in such capacity at least for
the balance of the current fiscal year of the Company and not to resign
voluntarily during such period without the written consent of a majority of the
Board of Directors.  Following the applicable period set forth above, Indemnitee
agrees to continue to serve in such capacity at the will of the Company (or
under separate agreement, if such agreement exists) so long as he is duly
appointed or elected and qualified in accordance with the applicable provisions
of the Bylaws of the Company or any subsidiary of the Company or until such time
as he tenders his resignation in writing.  Nothing contained in this Agreement
is intended to or shall create in Indemnitee any right to continued employment.

     3.  Expenses; Indemnification Procedure.
         -----------------------------------

         (a) Advancement of Expenses.  The Company shall advance all expenses
             -----------------------
incurred by Indemnitee in connection with the investigation, defense, settlement
or appeal of any civil or criminal action or proceeding referenced in Section
1(a) or (b) hereof (but not amounts actually paid in settlement of any such
action or proceeding).  Indemnitee hereby undertakes to repay such expenses
advanced only if, and to the extent that, it shall ultimately be determined that
Indemnitee is not entitled to be indemnified by the Company as authorized
hereby.  The advances to be made hereunder shall be paid by the Company to
Indemnitee within twenty (20) days following delivery of a written request
therefor by Indemnitee to the Company.

         (b) Notice/Cooperation by Indemnitee.  Indemnitee shall, as a
             --------------------------------
condition precedent to his right to be indemnified under this Agreement, give
the Company notice in writing as soon as practicable of any claim made against
Indemnitee for which indemnification will or could be sought under this
Agreement. Notice to the Company shall be directed to the Chief Executive
Officer of the Company at the address shown on the signature page of this
Agreement (or such other address as the Company shall designate in writing to
Indemnitee).  Notice shall be deemed received three business days after the date
postmarked if sent by domestic certified or registered mail, properly addressed;
otherwise notice shall be deemed received when such notice shall actually be
received by the Company.  In addition, Indemnitee shall give the Company such
information and cooperation as it may reasonably require and as shall be within
Indemnitee's power.

         (c) Procedure.  Any indemnification provided for in Section 1 shall be
             ---------
made no later than forty-five (45) days after receipt of the written request of
Indemnitee.  If a claim under this Agreement, under any statute, or under any
provision of the Company's Certificate of Incorporation or Bylaws providing for
indemnification, is not paid in full by the Company within forty-five (45) days
after a written request for payment thereof has first been received by the
Company, Indemnitee may, but need not, at any time thereafter submit his claim
to arbitration as described in Section 14 to  recover the unpaid amount of the
claim and, subject to Section 15 of this Agreement, Indemnitee shall also be
entitled to be paid for the expenses (including attorneys' fees) of bringing
such claim.  It shall be a defense to any such action (other than a claim
brought for expenses incurred in connection with any action or proceeding in
advance of its final disposition) that Indemnitee has not met the standards of
conduct which make it permissible under applicable law for the Company to
indemnify Indemnitee for the amount claimed, but the burden of proving such
defense shall be on the Company, and Indemnitee shall be entitled to receive
interim payments of expenses pursuant to Subsection 3(a) unless and until such
defense may be finally adjudicated by court order or judgment from which no
further right of appeal exists or an arbitration panel as described in Section
14.  It is the parties' intention that if the Company contests Indemnitee's
right to indemnification, the question of Indemnitee's right to indemnification
shall be for the court or arbitration panel to decide, and neither the failure
of the Company (including its Board of Directors, any committee or subgroup of
the Board of Directors, independent legal counsel, or its stockholders) to have
made a determination that indemnification of Indemnitee is proper in the
circumstances because Indemnitee has met

                                      -3-
<PAGE>

the applicable standard of conduct required by applicable law, nor an actual
determination by the Company (including its Board of Directors, any committee or
subgroup of the Board of Directors, independent legal counsel, or its
stockholders) that Indemnitee has not met such applicable standard of conduct,
shall create a presumption that Indemnitee has or has not met the applicable
standard of conduct.

         (d) Notice to Insurers.  If, at the time of the receipt of a notice of
             ------------------
a claim pursuant to Section 3(b) hereof, the Company has director and officer
liability insurance in effect, the Company shall give prompt notice of the
commencement of such proceeding to the insurers in accordance with the
procedures set forth in the respective policies.  The Company shall thereafter
take all necessary or desirable action to cause such insurers to pay, on behalf
of the Indemnitee, all amounts payable as a result of such proceeding in
accordance with the terms of such policies.

         (e) Selection of Counsel.  In the event the Company shall be obligated
             --------------------
under Section 3(a) hereof to pay the expenses of any proceeding against
Indemnitee, the Company, if appropriate, shall be entitled to assume the defense
of such proceeding, with counsel approved by Indemnitee, which approval shall
not be unreasonably withheld, upon the delivery to Indemnitee of written notice
of its election so to do.  After delivery of such notice, approval of such
counsel by Indemnitee and the retention of such counsel by the Company, the
Company will not be liable to Indemnitee under this Agreement for any fees of
counsel subsequently incurred by Indemnitee with respect to the same proceeding,
provided that (i) Indemnitee shall have the right to  employ his own counsel in
any such proceeding at Indemnitee's  expense; and (ii) if (A) the employment of
counsel by Indemnitee has been previously authorized by the Company, (B)
Indemnitee shall have reasonably concluded that there may be a conflict of
interest between the Company and Indemnitee in the conduct of any such defense
or (C) the Company shall not, in fact, have employed counsel to assume the
defense of such proceeding, then the fees and expenses of Indemnitee's counsel
shall be at the expense of the Company.

     4.  Additional Indemnification Rights; Nonexclusivity.
         -------------------------------------------------

         (a) Scope.  Notwithstanding any other provision of this Agreement, the
             -----
Company hereby agrees to indemnify the Indemnitee to the fullest extent
permitted by law, notwithstanding that such indemnification is not specifically
authorized by the other provisions of this Agreement, the Company's Certificate
of Incorporation, the Company's Bylaws or by statute.  In the event of any
change, after the date of this Agreement, in any applicable law, statute or rule
which expands the right of a Delaware corporation to indemnify a member of its
Board of Directors or an officer, such changes shall be, ipso facto, within the
                                                         ---- -----
purview of Indemnitee's rights and Company's obligations under this Agreement.
In the event of any change in any applicable law, statute or rule which narrows
the right of a Delaware corporation to indemnify a member of its Board of
Directors or an officer, such changes, to the extent not otherwise required by
such law, statute or rule to be applied to this Agreement shall have no effect
on this Agreement or the parties' rights and obligations hereunder.

                                      -4-
<PAGE>

         (b) Nonexclusivity.  The indemnification provided by this Agreement
             --------------
shall not be deemed exclusive of any rights to which Indemnitee may be entitled
under the Company's Certificate of Incorporation, its Bylaws, any agreement, any
vote of stockholders or disinterested directors, the General Corporation Law of
the State of Delaware, or otherwise, both as to action in Indemnitee's official
capacity and as to action in another capacity while holding such office.  The
indemnification provided under this Agreement shall continue as to Indemnitee
for any action taken or not taken while serving in an indemnified capacity even
though he may have ceased to serve in such capacity at the time of any action or
other covered proceeding.

     5.  Partial Indemnification.  If Indemnitee is entitled under any provision
         -----------------------
of this Agreement to indemnification by the Company for some or a portion of the
expenses, judgments, fines, penalties or amounts paid in settlement actually or
reasonably incurred by him in the investigation, defense, appeal or settlement
of any civil or criminal action or proceeding, but not, however, for the total
amount thereof, the Company shall nevertheless indemnify  Indemnitee for the
portion of such expenses, judgments, fines or penalties to which Indemnitee is
entitled.

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

     7.  Directors' and Officers' Liability Insurance.  The Company shall, from
         --------------------------------------------
time to time, make a good faith determination whether or not it is practicable
for the Company to obtain and maintain a policy or policies of insurance with
reputable insurance companies providing the officers and directors of the
Company with coverage for losses from wrongful acts, or to ensure the Company's
performance of its indemnification obligations under this Agreement.  Among
other considerations, the Company will weigh the costs of obtaining such
insurance coverage against the protection afforded by such coverage.  In all
policies of directors' and officers' liability insurance, Indemnitee shall be
named as an insured in such a manner as to provide Indemnitee the same rights
and benefits as are accorded to the most favorably insured of the Company's
directors, if Indemnitee is a director; or of the Company's officers, if
Indemnitee is not a director of the Company but is an officer; or of the
Company's key employees, if Indemnitee is not an officer or director but is a
key employee. Notwithstanding the foregoing, the Company shall have no
obligation to obtain or maintain such insurance if the Company determines in
good faith that such insurance is not reasonably available, if the premium costs
for such insurance are disproportionate to the amount of coverage provided, if
the coverage provided by such insurance is limited by exclusions so as to
provide an insufficient benefit, or if Indemnitee is covered by similar
insurance maintained by a subsidiary or parent of the Company.

                                      -5-
<PAGE>

     8.  Severability.  Nothing in this Agreement is intended to require or
         ------------
shall be construed as requiring the Company to do or fail to do any act in
violation of applicable law.  The Company's inability, pursuant to court order,
to perform its obligations under this Agreement shall not constitute a breach of
this Agreement.  The provisions of this Agreement shall be severable as provided
in this Section 8.  If this Agreement or any portion hereof shall be invalidated
on any ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify Indemnitee to the full extent permitted by any applicable
portion of this Agreement that shall not have been invalidated, and the balance
of this Agreement not so invalidated shall be enforceable in accordance with its
terms.

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

         (a)  Excluded Acts.  To indemnify Indemnitee for any acts or omissions
              -------------
or transactions from which a director may not be indemnified under the Delaware
General Corporation Law; or

         (b) Claims Initiated by Indemnitee.  To indemnify or advance expenses
             ------------------------------
to Indemnitee with respect to proceedings or claims initiated or brought
voluntarily by Indemnitee and not by way of defense, except with respect to
proceedings brought to establish or enforce a right to indemnification under
this Agreement or any other statute or law or otherwise as required under
Section 145 of the Delaware General Corporation Law, but such indemnification or
advancement of expenses may be provided by the Company in specific cases if the
Board of Directors has approved the initiation or bringing of such claim; or

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

         (d) Insured Claims.  To indemnify Indemnitee for  expenses or
             --------------
liabilities of any type whatsoever (including, but not limited to, judgments,
fines, ERISA excise taxes or penalties, and amounts paid in settlement) which
have been paid directly to Indemnitee by an insurance carrier under a policy of
directors' and officers' liability insurance maintained by the Company; or

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

                                      -6-
<PAGE>

    10.  Effectiveness of Agreement.  To the extent that the indemnification
         --------------------------
permitted under the terms of certain provisions of this Agreement exceeds the
scope of the indemnification provided for in the Delaware General Corporation
Law, such provisions shall not be effective unless and until the Company's
Certificate of Incorporation authorizes such additional rights of
indemnification. In all other respects, the balance of this Agreement shall be
effective as of the date set forth on the first page and may apply to acts or
omissions of Indemnitee which occurred prior to such date if Indemnitee was an
officer, director, employee or other agent of the Company, or was serving at the
request of the Company as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, at the time
such act or omission occurred.

    11.  Construction of Certain Phrases.
         -------------------------------

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

         (b) For purposes of this Agreement, references to "other enterprises"
shall include employee benefit plans; references to "fines" shall include any
excise taxes assessed on Indemnitee with respect to an employee benefit plan;
and references to "serving at the request of the Company" shall include any
service as a director, officer, employee or agent of the Company which imposes
duties on, or involves services by, such director, officer, employee or agent
with respect to an employee benefit plan, its participants, or beneficiaries.

         ------------
counterparts, each of which shall constitute an original.

    13.  Successors and Assigns.  This Agreement shall be binding upon the
         ----------------------
Company and its successors and assigns, and shall inure to the benefit of
Indemnitee and Indemnitee's estate, heirs, legal representatives and assigns.

    14.  Arbitration.  It is understood and agreed that the Company and
         -----------
Indemnitee shall carry out this Agreement in the spirit of mutual cooperation
and good faith and that any differences, disputes or controversies shall be
resolved and settled amicably among the parties hereto.  In the event that the
dispute, controversy or difference is not so settled in the above manner within
forty-five (45) days, then the matter shall be exclusively submitted to
arbitration in Santa Clara

                                      -7-
<PAGE>

accordance with the Commercial Arbitration Rules of the American Arbitration
Association and under the laws of Delaware, without reference to conflict of
laws principles. Subject to Sections 1(b) and 6, arbitration shall be the
exclusive forum and the decision and award by the arbitrator(s) shall be final
and binding upon the parties concerned and may be entered in any state court of
California having jurisdiction.

    15.  Attorneys' Fees.  In the event that any action is instituted or claim
         ---------------
is submitted to arbitration by Indemnitee under this Agreement to enforce or
interpret any of the terms  hereof, Indemnitee shall be entitled to be paid all
court costs and expenses, including reasonable attorneys' fees, incurred by
Indemnitee with respect to such action or arbitration, unless as a part of such
action, a court of competent jurisdiction or the arbitrator(s) determines that
each of the material assertions made by Indemnitee as a basis for such claim
were not made in good faith or were frivolous.  In the event of an action
instituted or a claim submitted to arbitration by or in the name of the Company
under this Agreement or to enforce or interpret any of the terms of this
Agreement, Indemnitee shall be entitled to be paid all court costs and expenses,
including attorneys' fees, incurred by Indemnitee in defense of such action or
claim (including with respect to Indemnitee's counterclaims and cross-claims
made in such action or arbitration), unless as a part of such action the court
or the arbitrator(s) determines that each of Indemnitee's material defenses to
such action or claim were made in bad faith or were frivolous.

    16.  Notice.  All notices, requests, demands and other communications under
         -------
this Agreement shall be in writing and shall be deemed duly given (i) if
delivered by hand and receipted for by the party addressee, on the date of such

prepaid, on the third business day after the date postmarked.  Addresses for

irrevocably consent to the jurisdiction of the courts of the State of California
for all purposes in connection with any proceeding which arises out of or
relates to this Agreement and agree that any action instituted under this
Agreement shall be brought only in the state courts of the State of California
in Santa Clara County and that any arbitration proceeding which arises out of or
relates to this Agreement shall be held in Santa Clara County, California.

    18.  Choice of Law.  This Agreement shall be governed by and its provisions
         -------------
construed in accordance with the laws of the State of Delaware as applied to
contracts between Delaware residents entered into and performed entirely within
Delaware.

    19.  Subrogation.  In the event of payment under this Agreement, the
         -----------
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of Indemnitee, who shall

                                      -8-
<PAGE>

execute all documents required and shall do all acts that may be necessary to
secure such rights and to enable the corporation effectively to bring suit to
enforce such rights.

    20.  Continuation of Indemnification.  All agreements and obligations of
         -------------------------------
the Company contained herein shall continue during the period that Indemnitee is
a director, officer or agent of the Company and shall continue thereafter so
long as Indemnitee shall be subject to any possible claim or threatened,
pending or completed action, suit or proceeding, whether civil,  criminal,
arbitrational, administrative or investigative, by reason of the fact that
Indemnitee was serving in the capacity referred to herein.

    21.  Amendment and Termination.  Subject to Section 20, no amendment,
         -------------------------
modification, termination or cancellation of this Agreement shall be effective
unless in writing signed by both parties hereto.

     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.

              (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 administered by a Committee of two or more "outside
directors" within the meaning of Section 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 and Stock
Purchase Rights may be granted hereunder;

              (iii) to determine the number of shares of Common Stock to be
covered by each Option and Stock Purchase Right 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, of any Option or Stock Purchase Right granted hereunder.
Such terms and conditions include, but are not limited to, the exercise price,
the time or times when Options or Stock Purchase Rights 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 Stock Purchase Right or the shares of Common Stock relating thereto, based in
each case on such factors as the Administrator, in its sole discretion, shall
determine;

                                      -4-
<PAGE>

              (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 or Stock Purchase Right
(subject to Section 15(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 or Stock Purchase Right that number of Shares having a Fair Market
Value equal to the amount required to be withheld. The Fair Market 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 or Stock Purchase Right
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 or Stock Purchase Rights.

     5. Eligibility. Nonstatutory Stock Options and Stock Purchase Rights 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 or Stock Purchase Right 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.

                                      -5-
<PAGE>

         (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 1,500,000 Shares.

             (ii) In connection with his or her initial service, a Service
Provider may be granted Options to purchase up to an additional 1,500,000
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 13.

             (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 13), the 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 19 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 15 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.

                                      -6-
<PAGE>

             (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.

         (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

                                      -7-
<PAGE>

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 dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 13 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

                                      -8-
<PAGE>

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.

         (e) Buyout Provisions. The Administrator may at any time offer to buy
             -----------------
out for a payment in cash or Shares an Option previously granted based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.

     11. Stock Purchase Rights.
         ---------------------

         (a) Rights to Purchase. Stock Purchase Rights may be issued either
             ------------------
alone, in addition to, or in tandem with other awards granted under the Plan
and/or cash awards made outside of the Plan. After the Administrator determines
that it will offer Stock Purchase Rights under the Plan, it shall advise the
offeree in writing or electronically, by means of a Notice of Grant, of the
terms, conditions and restrictions related to the offer, including the number of
Shares that the offeree shall be entitled to purchase, the price to be paid, and
the time within which the offeree must accept such offer. The offer shall be
accepted by execution of a Restricted Stock Purchase Agreement in the form
determined by the Administrator.

         (b) Repurchase Option. Unless the Administrator determines otherwise,
             -----------------
the Restricted Stock Purchase Agreement shall grant the Company a repurchase
option exercisable upon the voluntary or involuntary termination of the
purchaser's service with the Company for any reason (including death or
Disability). The purchase price for Shares repurchased pursuant to the
Restricted Stock Purchase Agreement shall be the original price paid by the
purchaser and may be paid by cancellation of any indebtedness of the purchaser
to the Company. The repurchase option shall lapse at a rate determined by the
Administrator.

         (c) Other Provisions. The Restricted Stock Purchase Agreement shall
             ----------------
contain such other terms, provisions and conditions not inconsistent with the
Plan as may be determined by the Administrator in its sole discretion.

         (d) Rights as a Shareholder. Once the Stock Purchase Right is
             -----------------------
exercised, the purchaser shall have the rights equivalent to those of a
shareholder, and shall be a shareholder when his or her purchase is entered upon
the records of the duly authorized transfer agent of the Company. No adjustment
will be made for a dividend or other right for which the record date is prior to
the date the Stock Purchase Right is exercised, except as provided in Section 13
of the Plan.

     12.  Non-Transferability of Options and Stock Purchase Rights.  Unless
          --------------------------------------------------------
determined otherwise by the Administrator, an Option or Stock Purchase Right 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

                                      -9-
<PAGE>

Optionee. If the Administrator makes an Option or Stock Purchase Right
transferable, such Option or Stock Purchase Right shall contain such additional
terms and conditions as the Administrator deems appropriate.

     13. 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 Stock Purchase Right, and the number of shares of
Common Stock which have been authorized for issuance under the Plan but as to
which no Options or Stock Purchase Rights have yet been granted or which have
been returned to the Plan upon cancellation or expiration of an Option or Stock
Purchase Right, 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 or Stock Purchase
Right, 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 or Stock Purchase Right.

         (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 or Stock Purchase Right 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 or Stock Purchase Right 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 and Stock Purchase Right 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 or Stock
Purchase Right, the Optionee shall fully vest in and have the right to exercise
the Option or Stock Purchase Right as to all of the Optioned Stock, including
Shares as to which it would not otherwise be vested or exercisable. If an Option
or Stock Purchase Right 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 or Stock Purchase Right shall be fully

                                      -10-
<PAGE>

vested and exercisable for a period of fifteen (15) days from the date of such
notice, and the Option or Stock Purchase Right shall terminate upon the
expiration of such period. For the purposes of this paragraph, the Option or
Stock Purchase Right shall be considered assumed if, following the merger or
sale of assets, the option or right confers the right to purchase or receive,
for each Share of Optioned Stock subject to the Option or Stock Purchase Right
immediately prior to the merger or sale of 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 or Stock
Purchase Right, for each Share of Optioned Stock subject to the Option or Stock
Purchase Right, 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.

     14.  Date of Grant.  The date of grant of an Option or Stock Purchase Right
          -------------
shall be, for all purposes, the date on which the Administrator makes the
determination granting such Option or Stock Purchase Right, 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.

     15.  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.

     16.  Conditions Upon Issuance of Shares.
          ----------------------------------

          (a) Legal Compliance. Shares shall not be issued pursuant to the
              ----------------
exercise of an Option or Stock Purchase Right unless the exercise of such Option
or Stock Purchase Right 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 or Stock Purchase Right, the Company may require the person exercising
such Option or Stock Purchase Right to represent and warrant at the time of any
such exercise that the Shares are being

                                      -11-
<PAGE>

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.

     17. 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 liability in respect
of the failure to issue or sell such Shares as to which such requisite authority
shall not have been obtained.

     18. 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.

     19.  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.

option (the "Option") to purchase the number of Shares, as set forth in the
Notice of Grant, at the exercise price per share set forth in the Notice of

which is incorporated herein by reference.  Subject to Section 15(c) of the

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

accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

         (b)  Method of Exercise.  This Option is exercisable by delivery of an
              ------------------
exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares 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.

         2.  check;

         3.  consideration received by the Company under a cashless exercise
program implemented by the Company in connection with the Plan; or

         4.  surrender of other Shares, provided Shares acquired from the
Company, have been owned by the Optionee for more than six (6) months on the
date of surrender, and (ii) have a Fair Market Value on the date of surrender
equal to the aggregate Exercise Price of the 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 may be exercised during the
lifetime of Optionee only by the Optionee. The terms of the Plan and this Option
Agreement shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

    E.   Term of Option.
         ---------------

         This Option may be exercised only within the term set out in the Notice
of Grant, and may be exercised during such term only in accordance with the Plan
and the terms of this Option Agreement.

    F.   Tax Obligations.
         ----------------

         1.  Withholding Taxes.  Optionee agrees to make appropriate
             -----------------
arrangements with the Company (or the Parent or Subsidiary employing or
retaining Optionee) for the satisfaction of all Federal, state, and local income
and employment tax withholding requirements applicable to the Option exercise.
Optionee acknowledges and agrees that the Company may refuse to honor the
exercise and refuse to deliver Shares if such withholding amounts are not
delivered at the time of exercise.

         2.  Notice of Disqualifying Disposition of ISO Shares.  If the Option

later of (1) the date two years after the Date of Grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition. Optionee agrees that Optionee may be

                               2BRIDGE SOFTWARE
                            1997 STOCK OPTION PLAN

1.  Adoption and Purpose of the Plan.  This stock option plan, to be known as
    --------------------------------
the "2Bridge Software 1997 Stock Option Plan" (but referred to herein as the
"Plan") has been adopted by the board of directors (the "Board") of 2Bridge
Software, a California corporation (the "Company"), and is subject to the
approval of its shareholders pursuant to section 8 below.  The purpose of this
Plan is to advance the interests of the Company and its shareholders by enabling
the Company to attract and retain qualified directors, officers, employees,
independent contractors, consultants and advisers by providing them with an
opportunity for investment in the Company.  The options that may be granted
hereunder ("Options") represent the right by the grantee thereof (each,
including any permitted transferee pursuant to section 7.3 below, an "Optionee")
to acquire shares of the Company's common stock ("Shares" which if acquired
pursuant to the exercise of an Option will be referred to as "Option Stock")
subject to the terms and conditions of this Plan and a written agreement between
the Company and the Optionee to evidence each such Option (an "Option
Agreement").

2.  Certain Definitions.  The defined terms set forth in Exhibit A attached
    -------------------                                  ---------
hereto and incorporated herein (together with other capitalized terms defined
elsewhere in this Plan) will govern the interpretation of this Plan.

3.  Eligibility.  The Company may grant Options under this Plan only to (i)
    -----------
persons who, at the time of such grant, are directors, officers and/or employees
of the Company and/or any of its Subsidiaries, and (ii) persons who, and
entities which, at the time of such grant, are independent contractors,
consultants or advisers of the Company and/or any of its Subsidiaries ("Eligible
Participants"); provided that no Option may be granted to any person after he or
she ceases, or to any entity after it ceases, for any reason, to be an Eligible
Participant (a "Loss of Eligibility Status").  Subject to the provisions of
section 4 of this Plan, there is no limitation on the number of Options that may
be granted to an Eligible Participant.

4.  Option Pool: Shares Reserved for Option.  In no event will the Company
    ---------------------------------------
issue, in the aggregate, more than three million four hundred eighty-five
thousand (3,485,000) Shares (the "Option Pool") pursuant to the exercise of all
Options granted under this Plan, exclusive of those Shares of Option Stock that
may be reacquired by the Company by repurchase or otherwise; provided that in
order to comply with the requirements of Section 260.140.45 of Title 10 of the
California Code of Regulations (the "30% Rule"), at no time will the total
number of Shares that either (x) may be acquired pursuant to the exercise of all
outstanding Options granted hereunder or under any other outstanding options or
warrants issued by the Company (exclusive of certain excluded rights and
warrants described in the 30% Rule), or (y) are provided for under any stock
bonus or similar plan of the Company, in the aggregate exceed 30% of the total
number of then issued and outstanding Shares of the Company (including shares of
convertible preferred stock or convertible senior common stock on an as
converted basis).  At all times while Options granted under this Plan are
outstanding, the Company will reserve for issuance for the purposes hereof a
<PAGE>

sufficient number of authorized and unissued Shares to fully satisfy the
Company's obligations under all such outstanding Options.

5.  Administration. This Plan will be administered and interpreted by the Board,
    --------------
or by a committee consisting of two or more members of the Board, appointed by
the Board for such purpose (the Board, or such committee, referred to herein as
the "Administrator").  Subject to the express terms and conditions hereof, the
Administrator is authorized to prescribe, amend and rescind rules and
regulations relating to this Plan, and to make all other determinations
necessary or advisable for its administration and interpretation.  Specifically,
the Administrator will have full and final authority in its discretion, subject
to the specific limitations on that discretion as are set forth herein and in
the Articles of Incorporation and Bylaws of the Company, at any time:

   (a)  to select and approve the Eligible Participants to whom Options will be
granted from time to time hereunder;

   (b)  to determine the Fair Market Value of the Shares as of the Grant Date
for any Option that is granted hereunder;

   (c)  with respect to each Option it decides to grant, to determine the terms
and conditions of that Option, to be set forth in the Option Agreement
evidencing that Option (the form of which also being subject to approval
by the Administrator), including at a minimum the following:

        (i) the total number of Shares of Option Stock that may be acquired by
the Optionee pursuant to that Option;

        (ii) whether that Option will be designated an "incentive stock option"
as defined in Section 422 of the Code (an "ISO"), in which case the Option will
be subject to all of the special provisions set forth in section 6 below;

        (iii) the per share purchase price to be paid to the Company by the
Optionee to acquire the Option Stock issuable upon exercise of the Option (the
"Option Price"); provided that the Option Price will not be less than eighty-
five percent (85%) of the Fair Market Value of the Shares as of the Grant Date,
unless the Optionee is a 10% shareholder, in which case the Option Price will
not be less than one hundred ten percent (110%) of such Fair Market Value;

        (iv) the maximum period or term during which that Option will be
exercisable (the "Option Term") and/or the last date on which that Option may be
exercised (the "Expiration Date"), provided that in no event may the Expiration
Date be later than, or the Option Term be longer than, ten (10) years from the
Grant Date.

        (v) the maximum period following any Loss of Eligibility Status with
respect to the Original Holder, whether resulting from his or her death,
disability or any other reason, during which period (the "Grace Period") the
Option will be exercisable, subject to the earlier end of the Option Term or the
Expiration Date, provided that if the Administrator fails to

                                      -2-
<PAGE>

specify such Grace Periods, but subject to the provisions of section 6(e) below
with respect to ISOs, the following Grace Periods will apply (and in no event
may the Administrator select Grace Periods that are shorter than the following):
(A) sixty (60) days after such Loss of Eligibility Status, other than by reason
of a Just Cause Termination or the Original Holder's death or disability, (B)
one hundred eighty (180) days after such Loss of Eligibility Status by reason of
the Original Holder's death or disability, and (C) thirty (30) days after such
Loss of Eligibility Status by reason of a Just Cause Termination of the Original
Holder;

        (vi) the form or forms of legal consideration in addition to cash
(including without limitation Shares and unexercised Vested Options, and, for an
Optionee who is an employee and/or director only, unsecured promissory notes)
that the Company will accept as payment of all or a portion of the Option Price
and/or Tax Withholding Liability to be paid by the Optionee upon the exercise of
an Option granted hereunder, and the fair market value of such non-cash
consideration;

        (vii) the conditions (e.g., the passage of time or the occurrence of
events), if any, that must be satisfied prior to the vesting of the right to
exercise all, or specified portions of an Option (such portions being described
as a percentage of the total number of Shares of Option Stock that may be
acquired by the Optionee pursuant to that Option; the vested portion being
referred to as a "Vested Option" and the unvested portion being referred to as
an "Unvested Option"); provided that no such conditions (except the Loss of
Eligibility Status of the Original Holder, after which no Unvested Option will
become a Vested Option) may be imposed which prevents an Optionee from
purchasing at least twenty percent (20%) of the Shares of Option Stock initially
subject to the Option as of the first anniversary of the Grant Date, and as of
each anniversary thereafter, such that by the fifth anniversary of the Grant
Date (assuming no such Loss of Eligibility Status) the entire Option would be
deemed a Vested Option; provided further that if the Option Agreement does not
otherwise specify, the Option will initially be deemed an entirely Unvested
Option but portions of the Option will become a Vested Option on the following
schedule: (A) twenty-five percent (25.0%) will become a Vested Option as of the
first anniversary of the Grant Date; and (B) two and one-twelfth percent
(2.083%) will become a Vested Option as of the first day of each month
thereafter, such that the Option will be a fully Vested Option as of the fourth
anniversary of the Grant Date, subject to the condition that the Original Holder
does not suffer a Loss of Eligibility Status prior to each such vesting date;
and

        (viii) in addition, or as an alternative, to imposing vesting conditions
on the right to exercise an Option as provided in section 5(c)(vii) above,
whether any portion of the Shares of Option Stock acquired by an Optionee upon
exercise of an Option will be subject to repurchase by the Company or its
assigns pursuant to section 7.4(c) below at the Option Price paid for such
Shares or at some other price that may be less than the Fair Market Value of
such Shares (such Shares, if subject to repurchase at less than Fair Market
Value, being referred to as "Unvested Shares") following a Loss of Eligibility
Status or other designated event, and the conditions (e.g., the passage of time
or the occurrence of events), if any, that must be satisfied for such Shares to
be no longer subject to such rights of repurchase at less than Fair Market Value
(such Shares being referred to as "Vested Shares"); provided that no such
conditions (except the Loss of Eligibility Status of the Original Holder, after
which no Unvested Shares will become

                                      -3-
<PAGE>

Vested Shares) may be imposed which prevent Unvested Shares from becoming Vested
Shares at the rate of at least twenty percent (20%) per year following the Grant
Date, such that by the fifth anniversary of the Grant Date (assuming no such
Loss of Eligibility Status) all of the Shares would be deemed Vested Shares;
provided further that no Shares acquired upon the exercise of an Option will be
deemed Unvested Shares unless specified in the Option Agreement; and

         (d) to delegate all or a portion of the Administrator's authority under
sections 5(a), (b) and (c) above to one or more members of the Board who also

6.  Special Provisions Relating to ISOs.  Notwithstanding anything else in this
    -----------------------------------
Plan to the contrary, the following provisions will apply to each Option granted
hereunder that is designated as an ISO pursuant to section 5(c)(ii) above and
that is intended to qualify for the treatment available pursuant to Section 422
of the Code:

         (a) such ISO may be granted only to Eligible Participants who, as of
the Grant Date, are employees of the Company and/or its Subsidiaries (as
determined by Section 3401(c) of the Code);

         (b) to the extent that the Fair Market Value of Option Stock
(determined as of the Grant Date) with respect to which all ISOs are exercisable
for the first time by any individual during any calendar year (pursuant to this
Plan and all other plans of the Company and/or its Subsidiaries) exceeds
$100,000, the Option will not be treated as an ISO;

         (c) the Option Price of an ISO will not be less than one hundred
percent (100%) of the Fair Market Value of the Shares as of the Grant Date,
except as set forth in section 6(d) below;

         (d) in the case of an ISO granted to an Optionee who is a 10%

Optionee who exercises any ISO more than (i) three (3) months following the
Original Holder's Loss of Eligibility Status other than by reason of his or her
death or permanent and total disability within the meaning of Section 22(e)(3)
of the Code, or (ii) twelve (12) months following such Original Holder's Loss of
Eligibility Status by reason or his or her permanent and total disability,
whichever case may be applicable.

7.  Additional Terms and Conditions of Stock Option Agreements.  No Option will
    ----------------------------------------------------------
be deemed granted hereunder merely upon the authorization thereof by the
Administrator, but will be deemed granted hereunder only upon the execution of
an Option Agreement evidencing the same by both the Optionee and a duly
authorized officer of the Company.  In addition to the terms and

                                      -4-
<PAGE>

conditions thereof to be determined by the Administrator pursuant to section
5(c) above, unless otherwise stated therein, each Option Agreement will be
deemed to include the following terms and conditions unless expressly waived by
the Company in the Option Agreement:

    7.1 Exercise of the Option; Issuance of Share Certificate. That portion of
        -----------------------------------------------------
the Option that is a Vested Option may be exercised by giving written notice
thereof to the Company, on such form as may be specified by the Administrator,
but in any event stating: the Optionee's intention to exercise the Option; the
date of exercise; the number of full Shares of Option Stock to be purchased
(which number will be no less than one hundred (100) Shares, without regard to
adjustments to the number of Shares subject to the Option pursuant to section 9
below, or, if less, all of the remaining Shares subject to the Option); the
amount and form of payment of the Option Price; and will contain such assurances
of the Optionee's investment intent as the Company may require to ensure that
the transaction complies in all respects with the requirements of the 1933 Act
and other applicable securities laws. The notice of exercise will be signed by
the person or persons exercising the Option. In the event that the Option is
being exercised by the representative of Optionee, the notice will be
accompanied by proof satisfactory to the Company of the representative's right
to exercise the Option. The notice of exercise will be accompanied by full
payment of the Option Price for the number of Shares of Option Stock to be
purchased, in United States dollars, in cash, by check made payable to the
Company, or in the form of such other legal consideration for the purchase of
Shares as may be approved by the Administrator, in its discretion pursuant to
section 5(c)(vi) above. In addition, to the extent required by applicable
federal, state, local or foreign law, and as a condition to the Company's
obligation to issue any Shares upon the exercise of the Option in full or in
part, Optionee will make arrangements satisfactory to the Company for the
payment of any applicable Tax Withholding Liability that may arise by reason of
or in connection with such exercise. Such arrangements may include, in the
Company's sole discretion, that the Optionee tender to the Company the amount of
such Tax Withholding Liability, in cash, by check made payable to the Company,
or in the form of such other payment as may be approved by the Administrator, in
its discretion pursuant to section 5(c)(vi) above. After receiving a proper
notice of exercise and payment of the applicable Option Price and withholding
taxes, the Company will cause to be issued a certificate or certificates for the
Shares of Option Stock as to which the Option has been exercised, registered in
the name of the person rightfully exercising the Option and, subject to sections
7.4(e) and 7.7 below, the Company will cause such certificate or certificates to
be delivered to such person.

     7.2 Compliance with Law. Notwithstanding any other provision of this Plan,
         -------------------
Options may be granted pursuant to this Plan, and Option Stock may be issued
pursuant to the exercise thereof by an Optionee, only after and on the condition
that there has been compliance with all applicable federal and state securities
laws. The Company will not be required to list, register or qualify any Shares
of Option Stock upon any securities exchange, under any state or federal law, or
with the Securities and Exchange Commission or any State agency, or secure the
consent or approval of any governmental regulatory authority, except that if at
any time the Board determines, in its discretion, that such listing,
registration or qualification of the Shares of Option Stock, or any such consent
or approval, is necessary or desirable as a condition of or in connection with
the exercise of an Option and the purchase of Shares of Option Stock thereunder,
that Option may not be exercised, in whole or in part, unless and until such
listing, registration, qualification,

                                      -5-
<PAGE>

consent or approval is effected or obtained free of any conditions that are not
acceptable to the Board, in its discretion. However, the Company will seek to
register or qualify with, or as may be provided by applicable local law, file
for and secure an exemption from such registration or qualification requirements
from, the applicable securities administrator and other officials of each
jurisdiction in which an Eligible Participant would be granted an Option
hereunder prior to such grant.

     7.3  Restrictions on Transfer.
          ------------------------

          (a) Options Nontransferable. No Option will be transferable by the
              -----------------------
Original Holder otherwise than by will or the laws of descent and distribution.
During the lifetime of the Original Holder, the Option will be exercisable only
by the Original Holder.

          (b) Prohibited Transfers. In addition to any other limitation on
              --------------------
Transfer created by applicable securities laws, prior to the Initial Public
Offering, no Holder of any Shares of Option Stock, may Transfer such Shares, or
any interest therein, except pursuant to a Permitted Transfer or as otherwise
expressly provided in this section 7, and in any event only after compliance
with the specific limitations and conditions set forth in this section 7 and
with all applicable securities laws. All transfers of Option Stock not complying
with the specific limitations and conditions set forth in this section 7 are
expressly prohibited. Any prohibited Transfer is void and of no effect, and no
purported transferee in connection therewith will be recognized as a Holder of
Option Stock for any purpose whatsoever. Should such a Transfer purport to
occur, the Company may refuse to carry out the Transfer on its books, attempt to
set aside the Transfer, enforce any undertakings or rights under this section 7,
or exercise any other legal or equitable remedy. For purposes of this section 7,
the term "Option Stock" includes all Shares issued by the Company to a Holder
(or his, her or its predecessor) by reason of such holdings, including any
securities which may be acquired as a result of a stock split, stock dividend,
and other distributions of Shares in the Company made upon, or in exchange for,
other securities of the Company.

          (c) Permitted Transfers. The Company's rights of first refusal and
              -------------------
repurchase set forth in section 7.4(a) and section 7.4(b) below will not apply
in the case of a Permitted Transfer. For such purposes, a "Permitted Transfer"
means any of the following: (i) a Transfer by will or under the laws of descent
and distribution; or (ii) a Transfer by a Holder of Option Stock to his or her
ancestors, descendants or spouse (other than pursuant to a decree of divorce,
dissolution or separate maintenance, a property settlement, or a separation
agreement or any similar agreement or arrangement with a spouse, except for bona
fide estate planning purposes), or to a trust, partnership, limited liability
company, custodianship or other fiduciary account for the benefit of the Holder
and/or such ancestors, descendants or spouse, including any Transfer in the form
of a distribution from any such trust, partnership, limited liability company,
custodianship or other fiduciary account to any of the foregoing permitted
beneficial owners or beneficiaries thereof.

                                      -6-
<PAGE>

         (d) Conditions to Transfer. It will be a condition to any Transfer of
             ----------------------
any Shares of Option Stock, in the case of either a Permitted Transfer or the
Company's failure or refusal to exercise its rights of first refusal under
section 7.4 below, that:

             (i) the transferee of the Shares will execute such documents as the
Company may reasonably require to ensure that the Company's rights under this
Plan, and any applicable Option Agreement, are adequately protected with respect
to such Shares, including, without limitation, the transferee's agreement to be
bound by all of the terms and conditions of this Plan and such Agreement, as if
he or she were the original Holder of such Shares; and

             (ii) the Company is satisfied that such Transfer complies in all
respects with the requirements imposed by applicable state and federal
securities laws and regulations.

         (e) Market Standoff. If in connection with any public offering of
             ---------------
securities of the Company (or any Successor Entity), the underwriter or
underwriters managing such offering so requests, then each Optionee and each
Holder of Shares of Option Stock will agree to not sell or otherwise Transfer
any such Shares (other than Shares included in such underwriting) without the
prior written consent of such underwriter, for such period of time as may be
requested by the underwriter (not to exceed 210 days) commencing on the
effective date of the registration statement filed with the Securities and
Exchange Commission in connection with such offering.

     7.4  Company Rights of Repurchase and First Refusal. The Company win have
          ----------------------------------------------
the following rights of repurchase and first refusal with respect to Shares of
Option Stock:

          (a) Company's Right of First Refusal. If any Holder proposes to
              --------------------------------
Transfer any Shares of Option Stock to any transferee, other than in the case of
an Involuntary Transfer subject to section 7.4(b) below, the Company will have
an assignable right (but not an obligation), prior to an Initial Public
Offering, to purchase such Shares on the terms and conditions set out in this
section 7.4(a). Such right of first refusal will be exercisable only on an all-
or-nothing basis as to any particular Transfer of Shares, in the following
manner:

              (i) The Holder proposing to Transfer such Shares will provide to
the Company a notice, of proposed Transfer (a "Proposed Transfer Notice")
stating: the number of Shares that the Holder proposes to Transfer and the
Holder's bona fide intention to Transfer such Shares; the names and addresses of
the Holder, the proposed transferee; the manner and date of such proposed
Transfer; and the bona fide cash price and/or other consideration (and the fair
market value thereof) per share, if any, that such Transferee has offered to pay
Holder for such Shares (the "Offered Price") as well as such other terms,
including payment terms, and conditions, if any, as were included in such offer
(the "Offered Terms"). If the Company subsequently requests additional
information concerning the proposed transferee, or the Offered Terms, the Holder
will attempt promptly to provide the requested information to the Company.

              (ii) The Company (or its assignee) may exercise its right of first
refusal under this section 7.4(a) by delivering to the Holder of such Shares a
notice of such

                                      -7-
<PAGE>

election, within thirty (30) days after the Company has received the Proposed
Transfer Notice, specifying a closing date that is no more than sixty (60) days
after receipt of the Proposed Transfer Notice (or such later date as the
transferee may have offered or on which the Transfer is otherwise scheduled to
occur).

              (iii) At such closing, to be held at the Company's principal
executive offices, the Company (or its assignee) will pay the Holder of the
Shares, in cash, the purchase price equal to the Offered Price (or, in the case
of a Donative Transfer of Shares of Option Stock, the Fair Market Value
thereof), subject to an appropriate adjustment to take into account any deferred
payment terms that were included in the Offered Terms; provided that if the
Offered Price includes any non-cash consideration, the value thereof for
purposes of this section 7.4(a) will be determined in good faith by the Board,
subject to section 7.4(d) below.

              (iv) If the Company (including its assignees) fails or refuses to
exercise its rights under this section 7.4(a) with respect to any Shares that
are the subject of any Proposed Transfer Notice, then the Holder will have the
right to Transfer such Shares to the transferee named in such Notice at the
Offered Price and upon such Offered Terms as were set forth in such Notice;
provided that such Transfer must be completed within ninety (90) days after the
Company has received the Proposed Transfer Notice with respect to such Shares.

          (b) Following an Involuntary Transfer. Following any Involuntary
Transfer of Shares of Option Stock (the "Transferred Shares"), the Company will
have the assignable right (but not the obligation), prior to an Initial Public
Offering, to purchase from the transferee of the Transferred Shares
("Transferee") all or a portion of such Shares for a purchase price that is
equal to the Fair Market Value of those Shares as of the date of such
Involuntary Transfer. Such right will be exercisable in the following manner:

              (i) The Transferee promptly after such Involuntary Transfer will
provide to the Company a notice of Transfer (an "Involuntary Transfer Notice")
stating: the number of Transferred Shares; the names and addresses of the
transferor and the Transferee; and the manner, circumstances and date of such
Involuntary Transfer. If the Company subsequently requests additional
information concerning the proposed transferee, or the Involuntary Transfer, the
Transferee will attempt promptly to provide the requested information to the
Company.

              (ii) The Company (or its assignee) may exercise its purchase
rights under this section 7.4(b) at any time not more than ninety (90) days
after the Company has received the Involuntary Transfer Notice with respect to
the Transferred Shares. If the Company (or its assignee) elects to exercise such
purchase rights it will do so by delivering to the Transferee a notice of such
election, specifying the number of Transferred Shares to be purchased and a
closing date that is no more than sixty (60) days after the giving of such
notice.

              (iii) At such closing, to be held at the Company's principal
executive offices, the Company (or its assignee) will pay the Transferee the
purchase price specified in this section 7.4(b). Following a Loss of Eligibility

<PAGE>

         (c) Following a Loss of Eligibility Status. Following any Loss of
             --------------------------------------
Eligibility Status by the Original Holder of an Option, the Company will have
the assignable right (but not the obligation) to purchase from the Holder of
Shares acquired pursuant to the exercise of the Option, all or a portion of such
Shares for a purchase price that (1) in the case of Unvested Shares pursuant to
section 5(c)(viii) above, is equal to the Option Price paid for such Shares, and
(2) in the case of Vested Shares, or Shares of Option Stock that were never
subject to Vesting pursuant to section 5(c)(viii) above, is equal to the greater
of (A) the Option Price per share paid upon the exercise of the Option pursuant
to which those Shares were issued, or (B) the Fair Market Value of those Shares
as of the date of such Loss of Eligibility Status. Such right will be
exercisable in the following manner:

             (i) The Company (or its assignee) may exercise its right of
repurchase under this section 7.4(c) at any time not more than ninety (90) days
after the effective date of the Loss of Eligibility Status of the Original
Holder of the Option (or if such Loss of Eligibility Status results from the
Original Holder's death or disability, a period of ninety (90) days after the
expiration of the Grace Period determined by the Administrator pursuant to
section 5(c)(v) above during which the Optionee would be able to exercise any
Vested Option), but in any event in the case of Vested Shares, prior to an
Initial Public Offering. If the Company (or its assignee) elects to exercise
such purchase rights it will do so by delivering to the Holder of such Shares a
notice of such election, specifying the number of Shares to be purchased and a
closing date that is within such ninety (90) day period.

             (ii) At such closing, to be held at the Company's principal
executive offices, the Company (or its assignee) will pay the Holder of the
Shares, the purchase price, as specified in this section 7.4(c), in cash, or by
cancellation of indebtedness to the Company, if any, incurred by the original
purchaser of the Option Stock to purchase the same, or both, at a closing to be
held at the Company's principal executive offices on the date specified in such
notice.

             (iii) Any assignment by the Company of its rights to purchase
Unvested Shares under this section 7.4(c) will be subject to the requirements of
Section 260.140.41(k) of Title 10 of the California Code of Regulations.

         (d) Resolution of Disputes. If there is a dispute concerning the fair
             ----------------------
market value of the consideration offered or accepted for the Shares of Option
Stock or the Fair Market Value of the Option Stock, in connection with the
exercise by the Company of its rights under this section 7.4, the dispute will
be resolved by the independent certified public accounting firm that audited or
prepared without audit the Company's last regular annual financial statement and
the determination of that firm will be binding on the parties in the absence of
fraud.

         (e) Escrow. For purposes of facilitating the enforcement of the
             ------
restrictions on Transfer set forth in this Plan or in any Option Agreement, the
Administrator may, at its discretion, require the Holder of Shares of Option
Stock to deliver the certificate(s) for such Shares with a stock power executed
by him or her and by his or her spouse (if required for Transfer), in blank, to
the Secretary of the Company or his or her designee, to hold said

                                      -9-
<PAGE>

certificate(s) and stock power(s) in escrow and to take all such actions and to
effectuate all such Transfers and/or releases as are in accordance with the
terms of this Plan. The certificates may be held in escrow so long as the Shares
of Option Stock whose ownership they evidence are subject to any right of
repurchase or of first refusal under this Plan or under an Option Agreement.
Each Optionee, by exercising an Option, thereby acknowledges that the Secretary
of the Company (or his or her designee) is so appointed as the escrow holder
with the foregoing authorities as a material inducement to the grant of an
Option under this Plan, that the appointment is coupled with an interest, and
that it accordingly will be irrevocable. The escrow holder will not be liable to
any party to an Option Agreement (or to any other party) for any actions or
omissions unless the escrow holder is grossly negligent relative thereto. The
escrow holder may rely upon any letter, notice or other document executed by any
signature purported to be genuine.

     7.5 Change of Control Transactions. Notwithstanding any other provision of
         ------------------------------
this Plan, in the event of a Change of Control Transaction (as defined herein):

         (a) with respect to all Options that have been granted hereunder and
that are outstanding as of the consummation of such Change of Control
Transaction, the Board, in its sole discretion, may determine that it is in the
best interests of the Company, and if so may take all appropriate action either
to:

             (i) cancel all such Options effective as of the consummation of the
Change of Control Transaction and, in connection with each Option, any portion
of which is a Vested Option, notify the Optionee of the proposed Change of
Control Transaction reasonably prior to its consummation so that the Optionee
will have an opportunity to exercise the Vested Option immediately prior to such
consummation; or

             (ii) require the Successor Entity in such Change of Control
Transaction to assume the outstanding Options or substitute therefor comparable
options of such Successor Entity (or of its parent or its Subsidiary); and

         (b) with respect to all Shares of Option Stock that have been issued
and that are outstanding as of the consummation of such Change of Control
Transaction, the Company will have the right (but not the obligation) to
repurchase all (but not less than all) of the Shares by paying the Holder
thereof cash, or cancelling any indebtedness of such Holder to the Company, or
both, at a closing to be held contemporaneously with the consummation of the
Change of Control Transaction, provided that the repurchase price for such
Shares (other than Unvested Shares pursuant to section 5(c)(viii) above)] will
be an amount per share that is equal to the Fair Market Value of the Shares
based on the Board's good faith estimate of the valuation of the Company implied
by the estimated fair market value of the total consideration to be paid in
connection with the Change of Control Transaction.

             (i) For purposes of this section 7.5: the term "Change of Control
Transaction" means a Business Combination in which less than sixty-six and two-
thirds percent (66.67%) of the outstanding voting securities of the Successor
Entity immediately following the consummation of the Business Combination
transaction are beneficially held by those persons and entities in the same
proportion as such persons and entities beneficially held the voting securities

                                      -10-
<PAGE>

of the Company immediately prior to such transaction; the term "Business
Combination" means a transaction or series of transactions consummated within
any period of ninety (90) days resulting in (A) the sale of all or substantially
all of the assets of the Company, (B) a merger or consolidation or other
reorganization in which the Company is not the surviving entity or becomes owned
entirely by another entity, or (C) the sale or other change of beneficial
ownership of at least thirty-three and one-third percent (33.33%) of the
outstanding voting securities of the Company.

     7.6 Additional Restrictions on Transfer; Investment Intent. By accepting an
         ------------------------------------------------------
Option and/or Shares of Option Stock under this Plan, the Optionee will be
deemed to represent, warrant and agree that, unless a registration statement is
in effect with respect to the offer and sale of Shares of Option Stock: (i)
neither the Option nor any such Shares will be freely tradeable and must be held
indefinitely unless such Option and such Shares are either registered under the
1933 Act or an exemption from such registration is available; (ii) the Company
is under no obligation to register the Option or any such Shares; (iii) upon
exercise of the Option, the Optionee win purchase the Shares of Option Stock for

beneficial interest in the Option Stock; (v) the Optionee has no present
intention of disposing of the Option Stock at any particular time; and (vi)

     7.7 Stock Certificates; Legends. Certificates representing Shares of Option
         ---------------------------
Stock will bear all legends required by law and necessary or appropriate in the
Administrator's discretion to effectuate the provisions of this Plan and of the
applicable Option Agreement. The Company may place a "stop transfer" order
against Shares of Option Stock until full compliance with all restrictions and
conditions set forth in this Plan, in any applicable Option Agreement and in the
legends referred to in this section 7.7.

     7.8 Notices. Any notice to be given to the Company under the terms of an
         -------
Option Agreement will be addressed to the Company at its principal executive
office, Attention: Corporate Secretary, or at such other address as the Company
may designate in writing. Any notice to be given to an Optionee will be
addressed to him or her at the address provided to the Company by the Optionee.
Any such notice win be deemed to have been duly given if and when enclosed in a
properly sealed envelope, addressed as aforesaid, deposited, postage prepaid, in
a post office or branch post office regularly maintained by the United States
Postal Service.

     7.9  Other Provisions.  Each Option Agreement may contain such other terms,
          ----------------
provisions and conditions, including restrictions on the Transfer of Shares of
Option Stock, and rights of the Company to repurchase such Shares, not
inconsistent with this Plan, as may be determined by the Administrator in its
sole discretion.

     7.10  Specific Performance.  Under those circumstances in which the Company
           --------------------
chooses to timely exercise its rights to repurchase Shares of Option Stock as
provided herein, the Company will be entitled to receive such Shares in specie
in order to have the same available for

                                      -11-
<PAGE>

future issuance without dilution of the holdings of other shareholders of the
Company. By accepting Shares of Option Stock, the Holder thereof therefore
acknowledges and agrees that money damages will be inadequate to compensate the
Company and its shareholders if such a repurchase is not completed as
contemplated hereunder and that the Company will, in such case, be entitled to a
decree of specific performance of the terms hereof or to an injunction
restraining such holder (or such Holder's personal representative) from
violating this Plan or Option Agreement, in addition to any other remedies that
may be available to the Company at law or in equity.

     7.11 No Shareholder Rights. No rights or privileges of a shareholder in the
          ---------------------
Company are conferred by reason of the granting of the Option. No Optionee will
become a shareholder in the Company with respect to any Shares of Option Stock
unless and until the Option has been properly exercised and the Option Price
fully paid as to the portion of the Option exercised.

8.  Term of the Plan.  This Plan will become effective on the date of its
    ----------------
adoption by the Board, provided this Plan is approved by the shareholders of the
Company (excluding Shares of Option Stock issued by the Company pursuant to the
exercise of Options granted under this Plan) within twelve (12) months before or
after that date.  If this Plan is not so approved by the shareholders of the
Company within that twelve (12) month period of time, any Options granted under
this Plan will be rescinded and will be void.  This Plan will remain in effect
until the tenth (10th) anniversary of the date of its adoption by the Board or
its approval by the shareholders of the Company, whichever is earlier, unless it
is terminated earlier pursuant to section 11 of this Plan.

9.  Adjustments Upon Changes in Stock.  In the event of any change in the
    ---------------------------------
outstanding Shares of the Company as a result of a stock split, reverse stock
split, stock dividend or distribution, recapitalization, combination or
reclassification, appropriate proportionate adjustments will be made in: (i) the
aggregate number of Shares that are reserved for issuance in the Option Pool
pursuant to section 4 above, under outstanding Options or future Options granted
hereunder; (ii) the Option Price and the number of Shares of Option Stock that
may be acquired under each outstanding Option granted hereunder; and (iii) other
rights and matters determined on a per share basis under this Plan or any Option
Agreement evidencing an outstanding Option granted hereunder.  Any such
adjustments will be made only by the Board, and when so made will be effective,
conclusive and binding for all purposes with respect to this Plan and all
Options then outstanding.  No such adjustments will be required by reason of the
issuance or sale by the Company for cash or other consideration of additional
Shares or securities convertible into or exchangeable for Shares.

10.  Modification, Extension and Renewal of Options; Governing Law.  Subject to
     -------------------------------------------------------------
the terms and conditions and within the limitations of this Plan, the
Administrator may modify, extend or renew outstanding Options granted under this
Plan, or accept the surrender of outstanding Options (to the extent not

any rights or obligations under any outstanding Option. This Plan will be

11.  Amendment and Discontinuance. The Board May amend, suspend or discontinue
     ----------------------------
this Plan at any time or from time to time; provided that no action of the Board
will cause ISOs granted under this Plan not to comply with Section 422 of the
Code unless the Board specifically declares such action to be made for that
purpose and provided further that no such action may, without the approval of
the shareholders of the Company, materially increase (other than by reason of an
adjustment pursuant to section 9 hereof) the maximum aggregate number of Shares
of Option Stock in the Option Pool, materially increase the benefits accruing to
Eligible Participants, or materially modify the category of, or eligibility
requirements for persons who are Eligible Participants.  However, no such action
may alter or impair any Option previously granted under this Plan without the
consent of the Optionee, nor may the number of Shares of Option Stock in the
Option Pool be reduced to a number that is less than the aggregate number of
Shares of Option Stock (i) that may be issued pursuant to the exercise of all
outstanding and unexpired Options granted hereunder, and (ii) that have been
issued and are outstanding pursuant to the exercise of Options granted hereunder
(net of any such Shares that have been reacquired by the Company by repurchase
or otherwise).

12.  Information Provided by Company.  Prior to an Initial Public Offering, the
     -------------------------------
Company annually will make available to each Optionee the Company's financial
statements (which statements need not be audited), and each Optionee will, by
virtue of entering into an Option Agreement, be deemed to have agreed (and to
cause any investment advisers to whom the Optionee proposes to make such
information available to agree) to keep such information confidential and not to
use such information for any purpose whatsoever other than determining whether
to exercise an Option.

13.  Copies of Plan.  A copy of this Plan will be delivered to each Optionee at
     --------------
or before the time he or she executes an Option Agreement.

<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 15% of the Compensation which he or
she receives on each pay day during the Offering Period; provided, however, that
should a pay day occur on an Exercise Date, a participant shall have the payroll
deductions made on such day applied to his or her account under the new Offering
Period or Purchase Period, as the case may be.

         (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 nature and/or 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

                                      -4-
<PAGE>

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 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

                                      -5-
<PAGE>

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 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 750,000 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)
750,000 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

                                      -6-
<PAGE>

determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

     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

                                      -7-
<PAGE>

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 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.

                                      -8-
<PAGE>

          (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 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.

                                      -9-
<PAGE>

     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.

     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.

                       2000 EMPLOYEE STOCK PURCHASE PLAN

                            SUBSCRIPTION AGREEMENT


_____ Original Application                          Enrollment Date:___________
_____ Change in Payroll Deduction Rate
_____ Change of Beneficiary(ies)

1.   ____________________ hereby elects to participate in the 2Bridge, 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 15%) 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:

     NAME:  (Please print)_____________________________________________________

             (vii) In the event that any Option granted under the Plan would
cause the number of Shares subject to outstanding Options plus the number of
Shares previously purchased under Options to exceed the Pool, then the remaining
Shares available for Option grant shall be granted under Options to the Outside
Directors on a pro rata basis. No further grants shall be made until such time,
if any, as additional Shares become available for grant under the Plan through
action of the Board or the shareholders to increase the number of Shares which
may be issued under the Plan or through cancellation or expiration of Options
previously granted hereunder.

     5. Eligibility. Options may be granted only to Outside Directors. All
        -----------
Options shall be automatically granted in accordance with the terms set forth in
Section 4 hereof.

        The Plan shall not confer upon any Optionee any right with respect to
continuation of service as a Director or nomination to serve as a Director, nor
shall it interfere in any way with any rights which the Director or the Company
may have to terminate the Director's relationship with the Company at any time.

     6. Term of Plan. The Plan shall become effective upon the earlier to occur
        ------------
of its adoption by the Board or its approval by the shareholders of the Company
as described in Section 16 of the Plan. It shall continue in effect for a term
of ten (10) years unless sooner terminated under Section 11 of the Plan.

     7. Form of Consideration. The consideration to be paid for the Shares to be
        ---------------------
issued upon exercise of an Option, including the method of payment, shall
consist of (i) cash, (ii) check, (iii) other Shares, provided Shares acquired
directly from the Company, (x) have been owned by the Optionee for more than six
(6) months on the date of surrender, and (y) 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, (iv) consideration received by the Company
under a cashless exercise program implemented by the Company in connection with
the Plan, or (v) any combination of the foregoing methods of payment.

     8.  Exercise of Option.
         ------------------

         (a) Procedure for Exercise; Rights as a Shareholder. Any Option granted
             -----------------------------------------------
hereunder shall be exercisable at such times as are set forth in Section 4
hereof; provided, however, that no Options shall be exercisable until
shareholder approval of the Plan in accordance with Section 16 hereof has been
obtained. An Option may not be exercised for a fraction of a Share.

         An Option shall be deemed to be exercised when written notice of such
exercise has been given to the Company in accordance with the terms of the
Option by the person entitled to exercise the Option and full payment for the
Shares with respect to which the Option is exercised has been received by the
Company.  Full payment may consist of any consideration and method of payment
allowable under Section 7 of the Plan.  Until the issuance (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company) of the stock certificate evidencing such Shares, no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Optioned Stock, notwithstanding the

                                      -4-
<PAGE>

exercise of the Option. A share certificate for the number of Shares so acquired
shall be issued to the Optionee as soon as practicable after exercise of the
Option. No adjustment shall be made for a dividend or other right for which the
record date is prior to the date the stock certificate is issued, except as
provided in Section 10 of the Plan.

          Exercise of an Option in any manner shall result in a decrease in the
number of Shares which thereafter may be 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 Continuous Status as a Director. Subject to Section
             ----------------------------------------------
10 hereof, in the event an Optionee's status as a Director terminates (other
than upon the Optionee's death or Disability), the Optionee may exercise his or
her Option, but only within three (3) months following the date of such
termination, and only to the extent that the Optionee was entitled to exercise
it on the date of such termination (but in no event later than the expiration of
its ten (10) year term). To the extent that the Optionee was not entitled to
exercise an Option on the date of such termination, and to the extent that the
Optionee does not exercise such Option (to the extent otherwise so entitled)
within the time specified herein, the Option shall terminate.

         (c) Disability of Optionee. In the event Optionee's status as a
             ----------------------
Director terminates as a result of Disability, the Optionee may exercise his or
her Option, but only within six (6) months following the date of such
termination, and only to the extent that the Optionee was entitled to exercise
it on the date of such termination (but in no event later than the expiration of
its ten (10) year term). To the extent that the Optionee was not entitled to
exercise an Option on the date of termination, or if he or she does not exercise
such Option (to the extent otherwise so entitled) within the time specified
herein, the Option shall terminate.

         (d) Death of Optionee. In the event of an Optionee's death, the
             -----------------
Optionee's estate or a person who acquired the right to exercise the Option by
bequest or inheritance may exercise the Option, but only within twelve (12)
months following the date of death, and only to the extent that the Optionee was
entitled to exercise it on the date of death (but in no event later than the
expiration of its ten (10) year term). To the extent that the Optionee was not
entitled to exercise an Option on the date of death, and to the extent that the
Optionee's estate or a person who acquired the right to exercise such Option
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.

     9.  Non-Transferability of Options.  The 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.

     10. 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 covered by each outstanding
Option, the number of Shares 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, as well

                                      -5-
<PAGE>

as the price per Share covered by each such outstanding Option, and the number
of Shares issuable pursuant to the automatic grant provisions of Section 4
hereof shall be proportionately adjusted for any increase or decrease in the
number of issued Shares 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 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." 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
subject to an Option.

         (b) Dissolution or Liquidation. In the event of the proposed
             --------------------------
dissolution or liquidation of the Company, to the extent that an Option has not
been previously exercised, it shall 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, outstanding Options may be assumed or equivalent options may be
substituted by the successor corporation or a Parent or Subsidiary thereof (the
"Successor Corporation"). If an Option is assumed or substituted for, the Option
or equivalent option shall continue to be exercisable as provided in Section 4
hereof for so long as the Optionee serves as a Director or a director of the
Successor Corporation. Following such assumption or substitution, if the
Optionee's status as a Director or director of the Successor Corporation, as
applicable, is terminated other than upon a voluntary resignation by the
Optionee, the Option or option shall become fully exercisable, including as to
Shares for which it would not otherwise be exercisable. Thereafter, the Option
or option shall remain exercisable in accordance with Sections 8(b) through (d)
above.

     If the Successor Corporation does not assume an outstanding Option or
substitute for it an equivalent option, the Option shall become fully vested and
exercisable, including as to Shares for which it would not otherwise be
exercisable.  In such event the Board shall notify the Optionee that the Option
shall be fully exercisable for a period of thirty (30) days from the date of
such notice, and upon the expiration of such period the Option shall terminate.

     For the purposes of this Section 10(c), an 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 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).
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

                                      -6-
<PAGE>

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.

     11.  Amendment and Termination of the Plan.
          -------------------------------------

          (a) Amendment and Termination. The Board may at any time amend, alter,
              -------------------------
suspend, or discontinue the Plan, but no amendment, alteration, suspension, or
discontinuation shall be made which would impair the rights of any Optionee
under any grant theretofore made, without his or her consent. In addition, to
the extent necessary and desirable to comply with any applicable law, regulation
or stock exchange rule, the Company shall obtain shareholder approval of any
Plan amendment in such a manner and to such a degree as required.

          (b) Effect of Amendment or Termination. Any such amendment or
              ----------------------------------
termination of the Plan shall not affect Options already granted and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated.

     12. Time of Granting Options. The date of grant of an Option shall, for all
         ------------------------
purposes, be the date determined in accordance with Section 4 hereof.

     13. Conditions Upon Issuance of Shares. 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 pursuant thereto shall comply with all relevant
provisions of law, including, without limitation, the Securities Act of 1933, as
amended, the Exchange Act, the rules and regulations promulgated thereunder,
state securities laws, 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 relevant provisions of law.

         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 liability in respect of the failure to issue or sell such
Shares as to which such requisite authority shall not have been obtained.

     14.  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.

     15.  Option Agreement. Options shall be evidenced by written option
          ----------------
agreements in such form as the Board shall approve.

                                      -7-
<PAGE>

     16.  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 degree and manner
required under applicable state and federal law and any stock exchange rules.

Common Stock (the "Optioned Stock"), at the price determined as provided herein,
and in all respects subject to the terms, definitions and provisions of the
Company's 2000 Director Option Plan (the "Plan") adopted by the Company which is
incorporated herein by reference.  The terms defined in the Plan shall have the
same defined meanings herein.

    1.  Nature of the Option.  This Option is a nonstatutory option and is not
         --------------------

    2.  Exercise Price.  The exercise price is $_______ for each share of Common
        --------------
Stock.

    3.  Exercise of Option.  This Option shall be exercisable during its term in
        ------------------
accordance with the provisions of Section 8 of the Plan as follows:

         (i)  Right to Exercise.
              -----------------
              (a) This Option shall become exercisable in installments
cumulatively with respect to [____] of the Optioned Stock on each anniversary of
its date of grant, so that one hundred percent (100%) of the Optioned Stock
shall be exercisable [_______] years after the date of grant; provided, however,
that in no event shall any Option be exercisable prior to the date the
stockholders of the Company approve the Plan.

              (b)  This Option may not be exercised for a fraction of a share.

              (c)  In the event of Optionee's death, disability or other
termination of service as a Director, the exercisability of the Option is
governed by Section 8 of the Plan.

         (ii) Method of Exercise.  This Option shall be exercisable by written
              ------------------
notice which shall state the election to exercise the Option and the number of
Shares in respect of which the Option is being exercised. Such written notice,
in the form attached hereto as Exhibit A, shall be signed by the Optionee and
shall be delivered in person or by certified mail to the Secretary of the
Company. The written notice shall be accompanied by payment of the exercise
price.

    4.  Method of Payment.  Payment of the exercise price shall be by any of the
        -----------------
following, or a combination thereof, at the election of the Optionee:

        (i)  cash;

       (ii)  check; or

<PAGE>

    (iii)  surrender of other Shares, provided Shares acquired from the Company,
(x) have been owned by the Optionee for more than six (6) months on the date of
surrender, and (y) 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; or

    (iv) delivery of a properly executed exercise notice together with such
other documentation as the Company and the broker, if applicable, shall require
to effect an exercise of the Option and delivery to the Company of the sale or
loan proceeds required to pay the exercise price.

    5.  Restrictions on Exercise.  This Option may not be exercised if the
        ------------------------
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulations, or if such issuance
would not comply with the requirements of any stock exchange upon which the
Shares may then be listed. As a condition to the exercise of this Option, the
Company may require Optionee to make any representation and warranty to the
Company as may be required by any applicable law or regulation.

    6.  Non-Transferability of Option.  This Option may not be transferred in

        --------------------------------
exercise of this Option, he or she will recognize income for tax purposes in an
amount equal to the excess of the then Fair Market Value of the Shares purchased
over the exercise price paid for such Shares. Since the Optionee is subject to
Section 16(b) of the Securities Exchange Act of 1934, as amended, under certain
limited circumstances the measurement and timing of such income (and the
commencement of any capital gain holding period) may be deferred, and the
Optionee is advised to contact a tax advisor concerning the application of
Section 83 in general and the availability a Section 83(b) election in
particular in connection with the exercise of the Option. Upon a resale of such
Shares by the Optionee, any difference between the sale price and the Fair
Market Value of the Shares on the

                                      -2-
<PAGE>

date of exercise of the Option, to the extent not included in income as
described above, will be treated as capital gain or loss.

     6. 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 may
be exercised during the lifetime of Optionee only by the Optionee. The terms of
this Option shall be binding upon the executors, administrators, heirs,
successors and assigns of the Optionee.

     7. Term of Option. This Option may not be exercised more than ten (10)
        --------------
years from the date of grant of this Option, and may be exercised during such
period only in accordance with the Plan and the terms of this Option.

     8. Taxation Upon Exercise of Option. Optionee understands that, upon
        --------------------------------
exercise of this Option, he or she will recognize income for tax purposes in an
amount equal to the excess of the then Fair Market Value of the Shares purchased
over the exercise price paid for such Shares. Since the Optionee is subject to
Section 16(b) of the Securities Exchange Act of 1934, as amended, under certain
limited circumstances the measurement and timing of such income (and the
commencement of any capital gain holding period) may be deferred, and the
Optionee is advised to contact a tax advisor concerning the application of
Section 83 in general and the availability a Section 83(b) election in
particular in connection with the exercise of the Option. Upon a resale of such
Shares by the Optionee, any difference between the sale price and the Fair
Market Value of the Shares on the

                                      -2-
<PAGE>

date of exercise of the Option, to the extent not included in income as
described above, will be treated as capital gain or loss.

the actual cost savings realized, or (B) are required under any governmental law
or regulation that was not applicable to the Building at the time this Lease was

reasonable period as Landlord shall determine together with interest on the
unamortized balance at the rate of 10 percent per year or such higher rate as
may have been paid by Landlord on funds borrowed for the purpose of constructing
such capital improvements; provided, however, that Operating Expenses shall not
                           --------  -------
include Property Taxes, depreciation on the Building other than depreciation on
personal property, costs of tenants' improvements, interest, capital items other

<PAGE>

interest). Actual Operating Expenses for both the Base Year and each subsequent
year of the term of this Lease shall be adjusted to equal Landlord's reasonable
estimate of Operating Expenses had the total rentable area of the Building been
occupied for both years. The determination of the costs of management,
operation, and maintenance of the Building and the costs of the capital
improvements referred to in clause (ii) above shall be in accordance with
generally accepted accounting principles consistently applied.

          (c)  Additional Rent on Account of Increases in Property Taxes. In

addition to Base Rent, Tenant, subject to Section 3(d), shall pay to Landlord as

the Building (or this Lease, the occupancy of Tenant, the sums payable by Tenant
hereunder, or in any manner relative to the subject matter hereof), excluding
only taxes covered by Section 6 hereof and federal and California income and
death taxes imposed with respect to Landlord. For purposes hereof, "taxes" is

impost, levy or the like levied by any governmental jurisdiction; and without
limiting the generality of the foregoing, "taxes" shall include any tax, fee,
excise, levy or other impost imposed by the United States, the State of
California or any political subdivision of the State (including any

                                       4.
<PAGE>

county, city, city and county, public corporation, district or any other
political entity or public corporation thereof), however described (including
any so-called value-added tax) as a direct substitution in whole or in part for,
or in addition to, real property taxes and assessments.

          (d)  Procedure. The additional rent provided under Sections 3(b) and
               ---------
3(c) above shall be paid in accordance with the following procedures:

               (i)  As soon as is practicable following the first anniversary of
this Lease and the end of each calendar year thereafter occurring during the
term of this Lease, Landlord shall give Tenant written notice of its estimate of
any increased amounts payable under Section 3(b) and/or 3(c). On or before the
first day of the calendar month next following such notice, Tenant shall pay to
Landlord that portion of the estimated amounts that already shall have accrued
and thereafter on or before the first day of each succeeding calendar month
shall pay a ratable portion of the balance remaining over the relevant period
covered. If for any reason such notice is not given as provided above, Tenant
shall continue to pay on the basis of the then applicable rental until the month
after such notice is given. If at any time or times Landlord determines that the
increased amounts payable under Sections 3(b) and/or 3(c) above will vary from
its estimate by more than 10 percent, Landlord shall, by notice to Tenant,
revise its estimate for such year, and subsequent payments by Tenant for such
year shall be based upon such revised estimate.

               (ii) Within 90 days after the close of each respective calendar
year during the term of this Lease subsequent to the Base Year (or as soon after
such 90-day period as practicable), Landlord shall deliver to Tenant a statement
of the adjustments to be made pursuant to Sections 3(b) and/or 3(c) above for
such calendar year which statement shall be audited and

                                       5.
<PAGE>

shall be prepared in accordance with generally accepted accounting principles,
and such statement shall be final and binding upon Landlord and Tenant. If on
the basis of such statement Tenant owes an amount that is less than the
estimated payments for such year previously made by Tenant, Landlord shall
refund such excess to Tenant within 30 days of the delivery of such statement.
If on the basis of the statement Tenant owes an amount that is more than the
estimated payments for such year previously made by Tenant, Tenant shall pay the
deficiency to Landlord within 30 days after delivery of the statement.

               (iii) If the date of the first anniversary of this Lease is a day
other than the first day of a calendar year, the amount of adjustment to be made
pursuant to Sections 3(b) and/or 3(c) above that is applicable to the calendar
year in which such first anniversary occurs shall be prorated on the basis that
the number of days from the first anniversary date to and including the last day
of such calendar year bears to 365.

               (iv)  If this Lease shall terminate on a day other than the last
day of a calendar year, the amount of adjustment to be made pursuant to Sections
3(b) and/or 3(c) above that is applicable to the calendar year in which such
termination occurs shall be prorated on the basis that the number of days from
the commencement of such year to and including the termination date bears to
365. The termination of this Lease shall not affect the obligations of Landlord
and Tenant pursuant to subparagraph (ii) of this Section 3(d) to be performed
after such termination.

          (e)  Rental Commencement. Base Rent shall be paid to Landlord (i) upon
               -------------------
the execution of this Lease for the first full month of the term of this Lease
for which rent is payable as set forth in the Basic Lease Information (as the
same may be deferred pursuant to Section 2(a)

                                       6.
<PAGE>

hereof), and (ii) with respect to the second full month and each successive
calendar month thereafter for which rent is payable, on or before the first day
of each such month. If this Lease commences on other than the first day of a
calendar month or ends on other than the last day of a calendar month, the
second and last installments of rent shall be pro-rated for the partial months
involved.

          (f)  No Deduction or Offset: Interest. All rental and all other sums
               --------------------------------
due and payable by Tenant to Landlord under any of the provisions of this Lease
shall be paid to Landlord, without abatement, deduction, offset, prior notice or
demand, in lawful money of the United States at Landlord's address for notices
or to such other person or at such other place as Landlord, from time to time,
may designate in writing. Tenant acknowledges that late payment by Tenant to
Landlord of rental or such sums will cause Landlord to incur costs not
contemplated by this Lease, the exact amount of such costs being extremely
difficult and impracticable to fix. Such costs include, without limitation,
processing and accounting charges, and late charges that may be imposed on
Landlord by the terms of any encumbrance and note secured by any encumbrance
covering the Building and/or the Premises. Therefore, if any installment of
rental or any other sum due and payable by Tenant to Landlord is not paid to and
received by Landlord within 10 days of the due date thereof (or, if Landlord has
notified Tenant in writing on two occasions during the 12 months preceding the
due date that Tenant has failed to pay rent or any other sum on the due date
thereof, then if Tenant fails to pay rent or other sum on the due date thereof):

               (i)  Tenant shall pay to Landlord an additional sum of five
percent (5%) of the overdue amount as a late charge. The parties agree that this
late charge represents a fair

                                       7.
<PAGE>

and reasonable estimate of the costs that Landlord will incur by reason of late
payment by Tenant; and

               (ii) the sums due and payable shall bear interest from date due
until paid at the highest rate legally permitted by applicable law. Acceptance
of any late charge or interest shall not constitute a waiver of Tenant's default
on the overdue amount, or prevent Landlord from exercising any of the other
rights and remedies available to Landlord.

     4.   Use. The Premises shall be used for general office purposes and no
          ---
others. Tenant shall neither do nor permit to be done in or about the Premises,
nor bring or permit to be brought or kept therein, anything which is prohibited
by or will in any way conflict with any law, statute, ordinance or governmental
rule or regulation now in force or which may hereafter be enacted or
promulgated, or which now or hereafter is prohibited by any insurance policy
carried by Landlord, or will in any way increase the existing rate of or affect
any fire or any other insurance upon the Building or any of its contents, or
cause a cancellation of any insurance policy covering the Building or any part
thereof or any of its contents. Tenant, in its own respect and in respect of its
agents, servants and invitees, shall neither do nor permit anything to be done
in or about the Premises or the Building or any part thereof which will in any
way obstruct or interfere with the rights of other tenants of the Building
(including any noise audible or any odor or vibrations observable from outside
the Premises), or injure or annoy them, or use or allow the Premises or the
Building or any part thereof to be used for any improper, unlawful or
objectionable purpose, nor shall Tenant cause, maintain or permit any nuisance
in, on or about the Premises or the Building or any portion thereof, or commit
or suffer to be committed any waste

                                       8.
<PAGE>

or damage in or about any of the same. Tenant shall not permit any materials to
be placed or stored in the common areas of the Building and shall not permit
debris to be placed therein, except in appropriate receptacles provided
therefor. Tenant, its agents, servants and invitees shall have the right on a 24
hour per day - seven day per week basis during the term hereof, subject to
compliance with Landlord's security procedures, to the (a) non-exclusive use of
the entrance lobby of the Building, its passenger and freight elevators, and the
common area of the floor of the Building in which the Premises are located, for
purposes of ingress to and egress from the Premises, and (b) the restrooms
located on the floor of the Building in which the Premises are located, and (c)
the exclusive use of the Premises. The provisions of Sections 11 and 12 of this
Lease shall apply to all such areas. Tenant shall not use any portion of the
Building (including, without limitation, the Building roof or portions of the
Building leased to other tenants) other than the Premises, excepting only as set
forth in the preceding sentence and such other portions of the Building as are
necessary for fire and other emergency ingress and egress purposes in accordance
with applicable law. Tenant shall not place any equipment in or otherwise
utilize the Premises in a manner that would exceed the floor load limits
specified by Landlord.

     5.   Services.
          --------

          (a)  Services - General. Landlord (subject to the further provisions
               ------------------
of this Section 5) shall furnish the Premises:

               (i)  during the period from 7 a.m. to 6 p.m., Monday through
Friday (except holidays), or such shorter period as may be prescribed by any
applicable policies or regulations adopted by any utility or governmental
agency, with heat and air conditioning in such amounts

                                       9.
<PAGE>

and at such temperatures as Landlord reasonably determines are required for
purposes of human comfort;

               (ii)  a reasonable amount of water;

               (iii) electricity for lighting and the operation of office
machines and any equipment installed pursuant to Exhibit B hereof, for which
purposes Landlord will provide Tenant with an electric allowance of 21,593
kilowatt-hours per month. Tenant shall pay to Landlord upon demand for all
electric power Landlord determines is consumed by Tenant in excess of such
allowance. The determination of the amount of Tenant's electric power
consumption shall be made by Landlord in good faith and shall be final, binding
and conclusive, provided that, if Tenant so elects, Landlord shall install at
Tenant's expense a separate electric meter to measure the electrical power
actually consumed by Tenant;

               (iv)  non-attended, or attended, at Landlord's election, elevator
service, and

               (v)   daily (one shift) janitor service Monday through Friday
(except holidays) which shall be provided by Landlord in the manner that such
service is customarily furnished in comparable office buildings in the area.

     Tenant shall notify Landlord within five (5) days following request thereby
of the nature and quantity of all Tenant's equipment and other items using
electricity in the Premises.

          (b)  Telecommunication Services. Landlord shall provide Tenant access
               --------------------------
to such quantity of pairs in the Building INC as is determined to be available
by Landlord in its sole discretion, taking into account the capacity of such
system and the present and anticipated needs of all building tenants. Tenant's
access to the INC shall be solely by arrangements made by the Tenant directly
with Pacific Bell or Landlord (or such vendor as Landlord may designate) as

                                      10.
<PAGE>

Tenant may elect, and Tenant shall pay all charges as may be imposed in
connection therewith. Tenant shall not itself (i) connect with or effect access
to the Building INC, or (ii) repair, modify, disturb or otherwise make any
access to or connection with the Building INC or its related equipment. Landlord
makes no warranty as to the quality, continuity or availability of the
telecommunications services in the Building, and Tenant hereby waives any claim
against Landlord for any actual or consequential damages (including damages for
loss of business) in the event Tenant's telecommunications services in any way
are interrupted, damaged or rendered less effective, except to the extent caused
by the grossly negligent or willful act or omission by Landlord, its agents or
employees. Tenant acknowledges that Landlord meets its duty of care to Tenant
with respect to the Building INC by contracting with a reliable third party
vendor to assume responsibility for the maintenance and repair thereof (which
contract contains provisions requiring such vendor to inspect the INC
periodically (the frequency of such inspections to be determined by such vendor
based on its experience and professional judgment), and requiring such vendor to
meet local and federal requirements for telecommunications material and
workmanship).

          (c)  Non-Liability. Landlord shall not be in default hereunder or be
               -------------
liable for any damage directly or indirectly resulting from, nor shall the
rental herein reserved be abated by reason of, (i) failure to furnish or delay
in furnishing any services as provided in this Section 5 when such failure or
delay is caused by accident or any condition beyond the control of Landlord or
by the making of repairs or improvements to the Premises or the Building
(including Building systems), or (ii) the limitation, curtailment, rationing or
restrictions on use of or the failure of the supply by the relevant utility to
Tenant of, water, electricity, gas, or any other form of utility

                                      11.
<PAGE>

services serving the Premises or the Building. Tenant expressly acknowledges
that all utility services are provided by the relevant utility involved, and
Landlord is to have no responsibility for the amount or quality of utility
services provided, including without limitation, the improper operation of
Tenant's equipment utilizing the same.

          (d)  Excess Electricity. Tenant, without the prior written consent of
               ------------------
Landlord, shall not use any apparatus or device in the Premises which alone or
collectively uses electricity in excess of the capacity of the electrical
circuits to the Premises installed pursuant to Exhibit B hereof, nor connect
with electric current, except through existing electrical outlets in the
Premises, any apparatus or device, for the purposes of using electric current.
If Tenant shall require electric current in excess of the capacity of the
electrical circuits to the Premises installed pursuant to Exhibit B hereof,
Tenant shall first obtain Landlord's consent to the installation of such
increased electrical capacity in accordance with the provisions of Section 7
hereof. Tenant agrees to pay Landlord for such excess electric current consumed
in excess of the allowance provided in Section 5(a) above.

          (e)  Excess Water. Tenant shall not use water in excess of that
furnished by Landlord for use of the Premises as general office space or connect
any apparatus or device for the purpose of using water. If Tenant shall require
water in excess of that usually furnished or supplied for use of the Premises as
general office space, Tenant shall first procure the written consent of Landlord
to the use thereof. Landlord, as a condition of Landlord's consent, may cause a
water meter to be installed, so as to measure the amount of excess water used.
The cost of any such meter and of installation, maintenance and repair thereof
shall be paid by Tenant, and Tenant agrees to pay to Landlord promptly upon
demand thereof by Landlord for all such excess

                                      12.
<PAGE>

water so used. Unless and until Landlord installs such separate meter, Tenant
shall pay to Landlord promptly upon demand Landlord's good faith estimate of the
cost of the excess of the amount of water used by Tenant over that usually
furnished or supplied by Landlord for use of the Premises as general office
space, and Landlord's estimate of such excess amounts, based upon the
independent judgment of Landlord's engineer, the manufacturer of the equipment
involved, or the utility providing the service, shall be final, binding, and
conclusive upon Tenant.

          (f)  Excess Air-Conditioning. Tenant (except as otherwise provided in
               -----------------------
Exhibit B) shall not use any apparatus or device in the Premises that will
increase the amount of air conditioning furnished by Landlord for general office
space.

     6.   Taxes Payable by Tenant. In addition to the monthly rental and other
          -----------------------
charges that are payable by Tenant hereunder, Tenant shall reimburse Landlord
upon demand for any and all taxes payable by Landlord whether or not now
customary or within the contemplation of the parties hereto which are upon,
measured by, or reasonably attributable to the cost or value of Tenant's
equipment, furniture, fixtures, and other personal property located in the
Premises or by the cost or value of any leasehold improvements made in or to the
Premises by or for Tenant, other than tenant improvements made and paid for by
Landlord hereunder, regardless of whether title to such improvements shall be in
Tenant or Landlord.

     7.   Alterations, Additions or Improvements. Except for the initial
          --------------------------------------
improvement of the Premises pursuant to Exhibit B, which shall be governed by
the provisions of Exhibit B, Tenant shall not make or suffer to be made any
alterations, additions, or improvements to or of the Premises or any part
thereof, or attach any fixtures or equipment thereto, without Landlord's prior
written consent. All such alterations, additions or improvements shall become
Landlord's

                                      13.
<PAGE>

property immediately and, at the end of the term hereof, shall remain on the
Premises without compensation to Tenant unless Landlord elects by notice to
Tenant given at the time of Landlord's consent to have Tenant remove the same,
in which event Tenant shall promptly remove such alternations, additions or
improvements, repair any damage to the Premises, and restore the Premises to
their condition prior to the installation of such alterations, additions or
improvements.

         Tenant at its expense shall obtain any and all permits and consents of
applicable governmental authorities in respect of such alterations, additions,
and improvements and shall comply with the requirements of all governmental
authorities in connection therewith, including all building codes; and Tenant
shall be liable to Landlord and shall reimburse Landlord for the costs of any
improvements to the Building (whether or not within the Premises) which may be
required by governmental authority as a consequence of Tenant's alterations,
additions and improvements.

         All alterations made by Tenant with the prior written consent of
Landlord shall be effected through the use of contractors approved by Landlord
who shall furnish to Landlord upon demand such completion bonds and labor and
material bonds as Landlord may require so as to assure completion of such
alterations, additions or improvements on a lien-free basis (and the furnishing
of the same shall not relieve Tenant of its obligation under Section 8 hereof).

         8.    Liens. Tenant shall keep the Premises and the Building free and
               -----
clear of and from any and all mechanics', materialmen's and other liens for work
or labor done, services performed and for materials used or furnished in or
about the Premises by or on behalf of Tenant. Tenant at all times shall pay and
discharge, promptly and fully, any and all claims upon which any such lien

                                      14.
<PAGE>

may or could be based, provided that Tenant in good faith may contest any such
lien if Tenant obtains and records a statutory lien release bond the effect of
which is that the lien is expunged from Landlord's title as a matter of law.
Tenant shall save, defend, indemnify and hold Landlord, the Premises and the
Building free and harmless of and from any and all such liens or claims of liens
or suits or other proceedings pertaining thereto.

     9.   Repairs. By entry hereunder, Tenant accepts the Premises as being in
          -------
the condition in which Landlord is obligated to deliver the Premises, subject
only to Landlord's Work. Tenant, at all times during the term hereof and at
Tenant's sole cost and expense, shall keep the Premises and every part thereof
in good condition and repair, excepting (a) ordinary wear and tear, and (b)
damage due to casualty with respect to which the provisions of Section 10 and 12
shall apply. Tenant hereby waives all right to make repairs at the expense of
Landlord or in lieu thereof to vacate the Premises as provided by California
Civil Code Section 1941 and 1942 or any other law, statute or ordinance now or
hereafter in effect. Landlord has no obligation and has made no promise to
alter, remodel, improve, repair, decorate, or paint the Premises or any part
thereof except as specifically herein set forth in Exhibit B. The maintenance of
the Building structure, Building systems, and common areas of the Building are
the sole responsibility of Landlord. Except as specifically set forth herein,
Landlord has not made any representations respecting the condition of the
Premises to Tenant.

     10.  Destruction or Damage.
          ---------------------

          (a)  Damage. If the Premises and/or other portion of the Building are
               ------
damaged by fire, earthquake, act of God, the elements, or other casualty,
Landlord shall forthwith repair the same, subject to the provisions of this
Section hereinafter set forth, if Landlord receives sufficient

                                      15.
<PAGE>

insurance proceeds to cover the cost thereof, and if such repairs, in Landlord's
opinion, can be made within 90 days following the issuance of any building
permit required by relevant governmental authority (the "Rebuilding Period").
This Lease shall remain in full force and effect except that, if such damage is
not the result of the negligence or willful misconduct of Tenant or Tenant's
employees or invitees, a proportional abatement of rental (based upon square
footage) shall be allowed Tenant for such part of the Premises as shall be
rendered unusable by Tenant in the conduct of its business during the time such
part is so unusable. Landlord's determination that such repair may be made
within the Rebuilding Period shall not obligate Landlord to complete the same
within such period. For purposes of this Section 10, "repairs" shall include all
repair and restorative work Landlord in Landlord's good faith but nevertheless
sole discretion deems advisable, including without limitation, all work and
improvements Landlord deems advisable to improve the condition and quality of
the Building, whether in the form of government mandated building code upgrades
or otherwise.

          (b)  Repair. If Landlord does not receive sufficient insurance
               ------
proceeds to cover the cost of such repairs, or if such repairs, in Landlord's
opinion, cannot be made within the Rebuilding Period, Landlord shall elect, by
notice to Tenant within 30 days after the date of such fire or other casualty:
(i) to repair or restore such damage, in which event this Lease shall continue
in full force and effect (except that the rent shall be partially abated as
hereinabove provided) and Landlord shall repair and restore such damage with
reasonable diligence, or (ii) to terminate this Lease, in which event this Lease
shall terminate as of the date of such fire or other casualty.

                                      16.
<PAGE>

          (c)  Waiver. Tenant waives California Civil Code Sections 1932(2) and
               ------
1933(4) providing for termination of hiring upon destruction of the thing hired.

          (d)  Costs of Repair. If the Premises are to be repaired under this
               ---------------
Section, Landlord (subject to the provisions of Section 12(b) hereof) shall
repair at its cost any injury or damage to the Building itself and the tenant
improvements in the Premises paid for by Landlord hereunder. Tenant shall repair
and pay the cost of repairing Tenant's alterations, Tenant's improvements,
Tenant's trade fixtures, Tenant's personal property and any other tenant
improvements in the Premises and shall be responsible for carrying such casualty
insurance as it deems appropriate with respect to such other tenant
improvements.

          (e)  Tenant's Right to Terminate Lease. If the Premises are not
               ---------------------------------
restored within one hundred eighty (180) days after the date of damage or
destruction, Tenant shall have the right to terminate this Lease.

     11.  Insurance; Waiver of Subrogation.
          --------------------------------

          (a)  Insurance. Tenant, at Tenant's expense, shall maintain in full
               ---------
force during the term hereof a policy or policies of comprehensive broad form
general public liability insurance insuring against claims and liability for
personal injury, death and property damage arising in or about the Premises, the
Building and adjoining areas or ways, with a carrier or carriers acceptable to
Landlord, and which carrier or carriers in any event shall have a rating of not
less than A Plus XIII by Best's Insurance Guide. The liability under such
insurance shall not be less than $2,000,000 combined single limit bodily injury
and property damage. Such policy or policies of insurance shall (a) name
Landlord and Landlord's lender as additional insureds, (b) be nonassessable,
primary and noncontributory with any policies carried by Landlord, and (c)
provide

                                      17.
<PAGE>

that the same may not be cancelled or materially amended except upon 30 days
prior written notice to Landlord. Tenant at all times shall maintain with
Landlord a current certificate or certificates of said policy or policies. The
amount of insurance coverage provided for in this Section shall be increased
from time to time during the term hereof upon demand of Landlord to the extent
reasonably required by circumstances then existing (including, but not limited
to increases in the cost of living as reflected in the Consumer Price Index
published by the U.S. Department of Labor and increases in personal injury and
wrongful death judgments or awards in the City and County of San Francisco).

          (b)  Subrogation. To the extent available without material incremental
               -----------
premium, each party shall obtain from its insurers under all policies of
property insurance maintained by such party at any time during the term hereof
insuring or covering the Premises, the Building or any portion thereof or
operations therein, a waiver of all rights of subrogation which the insurer
might have against the other party, and each party shall indemnify the other
party against any loss or expense, including reasonable attorneys' fees,
resulting from the failure to obtain such waiver to the extent the same is so
available.

     12.  Waiver; Indemnity.
          -----------------

          (a)  Tenant covenants and agrees that Landlord shall not at any time
after the date hereof or to any extent whatsoever be liable, responsible or in
anywise accountable for, and Tenant waives and releases any claim (including any
claim for contractual or implied indemnity) against Landlord, for Losses
(hereinafter defined) which at any time after the date hereof may be suffered or
sustained by:

               (i)  Tenant; or

                                      18.
<PAGE>

               (ii) Any person whosoever may at any time be using or occupying
          or visiting the Premises or be in, on or about the same, or in or
          about the common areas of the Building or the sidewalks adjacent
          thereto, and which Losses are caused in whole or in part by any act or
          omission (whether negligent, non-negligent or otherwise) of Tenant,
          its agents, servants and invitees;

and whether in case of either clause (i) and/or (ii) such Losses shall be caused
- -----------
in part by any act, omission or negligence of Landlord, its agents or servants,
except to the extent caused by the grossly negligent or willful act or omission
of Landlord, its agents or employees.

          (b)  In addition to, and not in limitation of (a) above, Tenant shall
forever indemnify, defend, hold and save Landlord and Landlord's Lender free and
harmless of, from and against any and all Losses caused in whole or in part by
any act or omission (whether negligent, non-negligent, or otherwise) of Tenant,
its agents servants and invitees and suffered or sustained by:

          (i)  Landlord; and/or

          (ii) any third person who asserts a claim against Landlord on account
thereof; and whether in case of either clause (i) and/or (ii) such Losses shall
         -----------
be caused in part by any act, omission or negligence of Landlord, its agents or
servants, except to the extent caused by the grossly negligent or willful act or
omission of Landlord, its agents or employees. The foregoing indemnity
obligation of Tenant shall include reasonable attorneys' fees, investigation
costs, and all other reasonable costs and expenses incurred by Landlord from the
first notice that any claim or demand is to be made or may be made.

                                      19.
<PAGE>

          (c)  For purposes hereof "Losses" shall mean any and all losses,
damages, costs and expenses, direct and indirect, actual and consequential, on
account of injury to or death of persons, or loss of or damage to property, of
any kind or nature, including without limitation, loss, injury, death, or damage
due to criminal act by third persons.

          (d)  The provisions of this Section 12 shall survive the termination
of this Lease with respect to any Losses occurring prior to such termination.
The insurance policy or policies required pursuant to the provisions of Section
11(a) by their terms shall cover the indemnity obligations of Tenant under
Section 12(b), except to the extent that any such obligation arises from
allegations of the willful misconduct of Tenant, its servants, or its agents.

     13.  Compliance with Legal Requirements.
          ----------------------------------

          (a)  General. During the term of this Lease, Tenant, with respect to

any court of competent jurisdiction or the admission by Tenant (excluding from
the term "admission" any settlement or consent decree which by its terms does
not admit Tenant's liability) in any action or proceeding against Tenant
(whether Landlord be a party thereto or not) that

                                      20.

governmental and regulatory approvals required under any Environmental
Requirements for any Environmental Activity by Tenant, including, without
limitation, the discharge of (appropriately treated) materials or wastes into or

                     (B) any claim relating to any Environmental Activity by
Tenant in, on or about the Premises, or that arises out of or in connection with
any Hazardous Materials in, on, under or about the Premises or removed from the
Premises; or

                     (C) any actual or threatened material release on, under or
about the Premises or any adjacent property of any Hazardous Material, except
any Hazardous Material whose discharge or emission is expressly authorized by
and in compliance with a permit issued by a federal, state, regional or local

and shall survive the expiration or earlier termination of the term of this
Lease.

               (vi) The provisions of this Section 13(b) shall survive the
termination of this lease.

     14.  Assignment and Subletting.
          -------------------------

          (a)  Assignment and Subletting. Except as expressly permitted pursuant
               -------------------------
to this Section, Tenant shall not, without the prior written consent of
Landlord, assign this Lease, or any interest herein, or sublet the Premises, or
any part thereof, or permit the use or occupancy of the Premises (or any right
or privilege appurtenant thereto) by any party other than Tenant. For purposes
hereof, "assignment" shall include any proposed disposition or transfer,
voluntary or involuntary, or hypothecation; and where Tenant is a (i)
partnership, "assignment" shall include a transfer of 25% or more of the equity
interest therein (other than to an existing equity holder) or (ii) a corporation
"assignment" shall include any (A) merger, consolidation or other reorganization
(involving the equity securities of Tenant) of Tenant, (B) liquidation,
dissolution or disposition of all or substantially all of the assets of Tenant
or (C) change in ownership of 40% or more of the

                                      23.
<PAGE>

equity interest therein except a transfer to an existing equity holder and
except with respect to a corporation whose stock is publicly traded). Any of the
foregoing acts without such consent of Landlord shall be void and shall, at the
option of Landlord, terminate this Lease. This Lease shall not, nor shall any
interest herein, be transferable or assignable as to the interest of Tenant by
operation of law without the written consent of Landlord. Notwithstanding the
foregoing, for purposes hereof, "assignment" shall not include any assignment by
Tenant to any corporation resulting from a merger or consolidation with Tenant,
or to any person or entity which acquires all the assets of Tenant as a going
concern in the business that is being conducted on the Premises, provided in
each instance that Tenant, or in the case of a sale of Tenant's assets, Tenant's
assignee, continues as an existing entity with substantially the same net worth
as the net worth of Tenant immediately prior to such transfer, assignment or
subletting, and before such assignment shall be effective, (i) the assignee
shall assume, in full, the obligations of Tenant under this Lease, and (ii)
Landlord shall be given written notice of such assignment and assumption. Any
such assignment shall not, in any way, affect or limit the liability of Tenant
under the terms of this Lease.

         Landlord's consent to any assignment or subletting of all or any part
of the Premises shall not be unreasonably withheld or delayed. Without limiting
the other instances in which it may be reasonable for Landlord to withhold its
consent to an assignment or subletting, Landlord and Tenant acknowledge that it
shall be reasonable for Landlord to withhold its consent from a proposed
assignment or subletting in the following instances:

                                      24.
<PAGE>

               (i)   If Landlord determines in its good faith but nevertheless
sole discretion that the use of the Premises by the proposed assignee or
sublessee would be in violation of Section 4 of this Lease;

               (ii)  If Landlord determines in its good faith but nevertheless
sole discretion that the financial worth of the proposed assignee or sublessee
does not meet the credit standards applied by Landlord for other tenants under
leases with comparable terms;

               (iii) If Landlord determines in its good faith but nevertheless
sole discretion that the proposed assignee or sublessee does not have a
favorable reputation as a tenant of property;

               (iv)  If Landlord has received from any prior lessor to the
proposed assignee or subtenant a negative report concerning such prior lessor's
experience with the proposed assignee or subtenant;

               (v)   If Landlord has experienced previous defaults by or is in
litigation with the proposed assignee or subtenant;

               (vi)  If the use of the Premises by the proposed assignee or
subtenant will violate any applicable law, ordinance or regulation, or any use
permit issued for the use and occupancy of the Premises.

          (b)  Information; Landlord's Options. If at any time, or from time to
               -------------------------------
time, during the term of this Lease, Tenant desires to assign, sublet or permit
the occupancy or use by another of all or any part of the Premises, Tenant shall
give notice to Landlord setting forth the following: (i) the name, address, and
legal composition of the proposed sublessee, occupier or user; (ii) the nature
of the business proposed to be carried on in the Premises (including proposed

                                      25.
<PAGE>

number of employees to be located in the Premises, the proposed equipment to be
used therein, proposed floor loads and proposed electrical loads); (iii) a copy
of the proposed assignment or sublease agreement; and (iv) any other
documentation or information requested by Landlord, including financial
information covering the proposed assignee, sublessee, occupier or user with
respect to such proposed subletting. All such information may be considered by
Landlord in making Landlord's permitted determinations hereunder, including the
granting or withholding of consent in respect of a proposed assignment or
subletting. Such notice, once so given, shall not be withdrawn or rescinded by
Tenant. Landlord shall have the options, exercisable by notice given to Tenant
within 10 days after Tenant's notice is given, to do the following:

               (i)  In the case of a proposed subletting, Landlord may sublet
from Tenant such space at the rental and other terms set forth in this Lease,
prorated where appropriate to reflect obligations allocable to that portion of
the Premises to be sublet, unless the rental to be paid by the proposed
sublessee is lower than the rental, as so prorated, payable under the Lease, in
which event such lower rental shall be payable by Landlord to Tenant, or

               (ii) In the case of either a proposed assignment or subletting,
Landlord may terminate this Lease as to that part or all of the Premises
proposed to be assigned or sublet, and in the case of termination as to a
portion of the Premises, Tenant's obligations under the Lease as to the balance
of the Premises remaining shall be proportionately reduced.

         If Landlord sublets such space or terminates the Lease as to such
space, in each instance leaving a portion of the Premises occupied by Tenant,
Tenant shall provide Landlord without charge reasonable and appropriate access
to such space and reasonable use of any common areas and facilities appurtenant
thereto. For purposes hereof, "common area" shall mean the total area

                                      26.
<PAGE>

on a floor consisting of rest rooms, janitor, telephone and electrical closets,
mechanical areas, and public corridors providing access to tenant space on such
floor, but excluding public stairs, elevator shafts and pipeshafts, together
with the enclosing walls thereof.

          (c)  Assignment or Subletting Conditions. Subject to (i) the other
               ------------------------ ----------
provisions of this Section 14 and (ii) Landlord's consent, which shall not be
unreasonably withheld or delayed, Tenant may assign or sublet such space to any
third party on the following conditions:

               (i)   In the case of a sublease, the same shall be subject and
subordinate to all of the provisions, terms and conditions of this Lease,

               (ii)  No assignment or sublease shall be valid and no assignee or
sublessee shall take possession of the Premises assigned or subleased until an
executed counterpart of such assignment or sublease, in form and substance
satisfactory to Landlord, shall have been delivered to Landlord, and Landlord
shall have expressly consented thereto in writing,

               (iii) No assignee or sublessee shall have a further right to
assign or sublet,

               (iv)  An amount equal to 50% of all sums or other economic
consideration received by Tenant as a result of such assignment or subletting,
however denominated (whether as consideration for the assignment, rentals under
a sublease, or otherwise), which exceed in aggregate the total sums which Tenant
(or Tenant's assignee in case of an assignment) is obligated to pay Landlord
under this Lease (after deducting (a) bona fide charges for services provided by
the Tenant to subtenants at rates that are comparable to and not in excess of
rates charged for similar services in the area, and (b) Tenant's actual out-of-
pocket costs of such assignment or subletting, not to exceed $15 per net
rentable square foot multiplied by the number of net rentable square feet
involved, which deduction shall be amortized in the case

                                      27.
<PAGE>

of a subletting in equal monthly installments over the term of the sublease),
prorated to reflect obligations allocable to that portion of the Premises
subject to such assignment or sublease, shall be payable to Landlord as
additional rental under this Lease without affecting or reducing any other
obligations of Tenant hereunder, provided that (A) in no event shall Tenant be
obligated to pay Landlord less than the rental specified in this Lease, and (B)
there are excluded from this clause (iv) any sublease or subleases totaling less
than 30% of the rentable area of the Premises, which exclusion is based on the
condition that at no time during the term of this lease shall there be any
assignment or subletting of 30% or more of the rentable area of the Premises,
(and in the event of the failure of such condition at any time this clause (iv)
shall apply to any consideration thereafter received on account of any
assignment or subletting, including the subletting of less than 30% of the
rentable area of the Premises to which the exclusion otherwise would apply). The
parties hereto acknowledge and agree that it is not their intention that
Tenant's leasehold interest in the Premises have any bonus value or marketable
value to Tenant even though the rentals provided for herein may from time to
time be less than the fair market rental value of the Premises.

               (v)  Tenant shall immediately and irrevocably assign to Landlord,
as security for Tenant's obligations under this Lease, all rental from any
subletting of all or a part of the Premises as permitted by this Lease, and
Landlord, as assignee and as attorney-in-fact for Tenant, or a receiver for
Tenant appointed on Landlord's application, may collect such rental and apply it
towards Tenant's obligations under this Lease; except that, until the occurrence
of an Event of Default by Tenant as defined in Section 17, Tenant shall have the
right to collect such rental.

                                      28.
<PAGE>

          (d)  Primary Liability. Regardless of Landlord's consent, no
               -----------------
subletting or assignment shall release Tenant of Tenant's obligation or alter
the primary liability of Tenant to pay the rental and to perform all other
obligations to be performed by Tenant hereunder. The acceptance of rental by
Landlord from any other person shall not be deemed to be a waiver by Landlord of
any provision hereof. Consent to one assignment or subletting shall not be
deemed consent to any subsequent assignment or subletting. In the event of
default by any assignees of Tenant or any successor of Tenant in the performance
of any of the terms hereof, Landlord may proceed directly against Tenant without
the necessity of exhausting remedies against such assignee or successor.
Landlord may consent to subsequent assignments or subletting of this Lease or
amendments or modifications to this Lease with assignees of Tenant, without
notifying Tenant, or any successor of Tenant, and without obtaining its or their
consent thereto, and such action shall not relieve Tenant of liability under
this Lease, provided that any such amendments or modifications shall not
increase Tenant's liability hereunder.

          (e)  Attorneys' Fees. If Tenant shall assign or sublet the Premises or
               ---------------
request the consent of Landlord to any assignment or subletting, or if Tenant
shall request the consent of Landlord for any act that Tenant proposes to do,
then Tenant shall pay Landlord's reasonable attorneys' fees incurred in
connection therewith.

          (f)  Conflicting Provisions. The provisions of this Section shall
               ----------------------
prevail and govern over any conflicting provision in any assignment or
subletting to which Landlord gives written consent. Any modification of the
terms of this Lease as between Tenant and Sublessee shall be void and will not
be binding on the Landlord.

                                      29.
<PAGE>

          (g)  Brokerage. Tenant shall forever save, indemnify and hold Landlord
               ---------
harmless from any and all claims for real estate brokerage of persons claiming
by or through Tenant arising from any assignment or subletting.

     15.  Rules. Tenant shall faithfully observe and comply with the rules and
          -----
regulations annexed to this Lease and, after notice thereof, all reasonable
modifications thereof and additions thereto from time to time promulgated in
writing by Landlord. Landlord shall not be responsible to Tenant for the
nonperformance by any other tenant or occupant of the Building of any of said
rules and regulations.

     16.  Entry by Landlord. Landlord may enter the Premises at reasonable hours
          -----------------
to (a) inspect the same, (b) exhibit the same to prospective purchasers,
lenders, or tenants, (c) determine whether Tenant is complying with all its
obligations hereunder, (d) supply janitor service and any other service to be
provided by Landlord to Tenant hereunder, (e) post notices of nonresponsibility
and (f) make repairs in the Premises or repairs to any adjoining space or
utility services or make repairs, alterations or improvements to any other
portion of the Building (provided, however, that all such work shall be done as
promptly as reasonably possible and so as to cause as little interference to
Tenant as reasonably possible). Without limiting the foregoing, Landlord may, at
any time or from time to time during the term of this Lease, perform substantial
renovation work in and to the Building or the systems serving the Building
(which work may include, but need not be limited to, the repair or replacement
of the Building's exterior facade, exterior window glass, elevators, electrical
systems, air conditioning and ventilating systems, plumbing system,
telecommunications system, common hallways, or lobby), any of which work may
require access to the same from within the Premises. Tenant agrees that (a)
Landlord shall

have access to the Premises at all reasonable times, upon reasonable notice, for
the purpose of performing such work, and (b) Landlord shall incur no liability
to Tenant, nor shall Tenant be entitled to any abatement of rent on account of
any noise, vibration, or other disturbance to Tenant's business at the Premises
(provided that Tenant is not denied access to said Premises and Tenant's ability
to conduct its business on the Premises is not substantially impaired thereby)
which shall arise out of said access by Landlord or by the performance by
Landlord of the aforesaid renovations at the Building. Landlord shall use
reasonable efforts (which shall not include any obligation to employ labor at
overtime rates) to avoid disruption of Tenant's business during any entry upon
the Premises by Landlord permitted by this Section 16.

         Tenant hereby waives any claim for damages for any injury or
inconvenience to or interference with Tenant's business, any loss of occupancy
or quiet enjoyment of the Premises or any other loss occasioned by any such
entry or entries made by Landlord pursuant to any of the foregoing. Landlord
shall at all times have and retain keys with which to unlock all of the doors
in, on or about the Premises (excluding Tenant's vaults, safes and similar areas
designated in writing by Tenant and approved by Landlord in advance); and
Landlord shall have the right to use any and all means which Landlord may deem
proper to open such doors in an emergency in order to obtain entry to the
Premises, and any entry to the Premises obtained by Landlord by any of said
means, or otherwise, shall not under any circumstances be construed or deemed to
be a forcible or unlawful entry into or a detainer of the Premises or an
eviction, actual or constructive, of Tenant from the Premises, or any portion
thereof.

         17.   Events of Default. The occurrence of any one or more of the
               -----------------
following events (an "Event of Default") shall constitute a breach of this Lease
by Tenant: (a) if Tenant shall fail to

                                      31.
<PAGE>

pay rent or any other sum when and as the same becomes due and payable and such
failure shall continue for more than 10 days (except that if Landlord has
notified Tenant in writing on two occasions during the 12 months preceding the
due date that Tenant has failed to pay rent or any other sum on the due date,
then the failure to pay such rent or other sum on the due date shall constitute
an Event of Default); or (b) if Tenant shall default in the performance or
observance of any other term hereof or of the rules and regulations described in
Section 15 to be performed or observed by Tenant, and within 30 days following
written notice from Landlord to Tenant, Tenant shall have failed to completely
cure such default, or if the nature of such default is such that it cannot
reasonably be cured within such 30 day period, Tenant shall not within such 30
day period have commenced with prompt diligence the curing of such default, or,
having so commenced, shall thereafter have failed to prosecute with prompt
diligence the complete curing of such default; or (c) if Tenant shall make a
general assignment for the benefit of creditors, or shall admit in writing its
inability to pay its debts as they become due, or shall file a petition in
bankruptcy, or shall be adjudicated a bankrupt or as insolvent, or shall file a
petition in any proceeding seeking any reorganization, arrangement, composition,
readjustment, liquidation, dissolution, or similar relief under any present or
future statute, law, or regulation, or shall file an answer admitting, or fail
to protest timely the material allegations of a petition filed against it in any
such proceeding, or shall seek or consent to or acquiesce in the appointment of
any trustee, receiver, or liquidator of Tenant or any material part of its
properties; or (d) if within 45 days after the commencement of any proceeding
against Tenant seeking any reorganization, arrangement, composition,
readjustment, liquidation, dissolution, or similar relief under any present or
future statute, law, or regulation, such proceeding shall not have been
dismissed, or if, within 30 days after the

                                      32.
<PAGE>

appointment without the consent or acquiescence of Tenant, of any trustee,
receiver, or liquidator of Tenant or of any material part of its properties,
such appointment shall not have been vacated; or (e) if this Lease or any estate
of Tenant hereunder shall be levied upon under any attachment or execution and
such attachment or execution is not vacated within 30 days; or (f) if Tenant
shall abandon or surrender the Premises, or be dispossessed by process of law or
otherwise, or shall vacate or fail to take possession of the Premises.

         18.   Landlord's Right to Terminate. If an Event of Default shall
               -----------------------------
occur, Landlord at any time thereafter may give a written termination notice to
Tenant, and on the date specified in such notice (which shall be not less than
three days after the giving of such notice) Tenant's right to possession shall
terminate, unless on or before such date all delinquent rent and all other sums
payable by Tenant under this Lease and all costs and expenses incurred by or on
behalf of Landlord hereunder shall have been paid by Tenant and all other
breaches of this Lease by Tenant at the time existing shall have been fully
remedied to the satisfaction of Landlord. Landlord may remove all persons and
property located therein and hold, administer and dispose of any or all of such
properties in accordance with applicable California law, including California
Civil Code Section 1980 et seq. and California Code of Civil Procedure Section
                        -- ---
1174. Landlord may do all things Landlord deems necessary in order to relet the
Premises, including, without limitation any alterations, repair and/or
restoration of the Premises. Upon such termination, Landlord may recover from
Tenant: (a) the worth at the time of award of the unpaid rental which had been
earned at the time of termination; (b) the worth at the time of award of the
amount by which the unpaid rental which would have been earned after termination
until the time of award exceeds the amount of such rental loss that Tenant
proves could have been reasonably avoided; (c) the worth

                                      33.
<PAGE>

at the time of award of the amount by which the unpaid rental for the balance of
the term of this Lease after the time of award exceeds the amount of such rental
loss that Tenant proves could be reasonably avoided; and (d) any other amount
necessary to compensate Landlord for all the detriment proximately caused by
Tenant's failure to perform its obligations under this Lease or which in the
ordinary course of things would be likely to result therefrom. The "worth at the
time of award" of the amounts referred to in clauses (a) and (b) above is
computed by allowing interest at the highest rate legally permitted under
applicable law. The "worth at the time of award" of the amount referred to in
clause (c) above is computed by discounting such amount at the discount rate of
the Federal Reserve Bank of San Francisco at the time of award plus 1% (one
percent). Notwithstanding any other provisions hereof, any efforts by Landlord
to mitigate damages caused by Tenant's breach of this Lease shall not constitute
a waiver of Landlord's right to recover damages hereunder and shall not affect
the right of Landlord to indemnification pursuant to the provisions of Section
12 hereof.

         19.  Continuation Notwithstanding Default. Even though Tenant has
              ------------------------------------
breached this Lease and abandoned the Premises, this Lease shall continue in
effect for so long as Landlord does not terminate Tenant's right to possession,
and Landlord may enforce all its rights and remedies under this Lease, including
the right to recover the rental as it becomes due under this Lease. Acts of
maintenance or preservation or efforts to relet the Premises or the appointment
of a receiver upon the initiative of Landlord to protect Landlord's interest
under this Lease shall not constitute a termination of Tenant's right to
possession.

         20.  Additional Remedies. The remedies provided for in this Lease are
              -------------------
in addition to any other remedies available to Landlord at law or in equity by
statute or otherwise.

                                      34.
<PAGE>

     21.  Landlord's Right to Cure Defaults. All agreements and provisions to be
          ---------------------------------
performed by Tenant under any of the terms of this Lease shall be at its sole
cost and expense and without any abatement of rental. If Tenant shall fail to
pay any sum of money, other than rental, required to be paid by it hereunder, or
shall fail to perform any other act on its part to be performed hereunder and
such failure shall continue for 10 days after notice thereof by Landlord,
Landlord may, but shall not be obligated to do so, and without waiving or
releasing Tenant from any obligations of Tenant, make any such payment or
perform any such other act on Tenant's part to be made or performed as in this
Lease provided. All sums so paid by Landlord and all necessary incidental costs
shall be deemed additional rent hereunder and shall be payable to Landlord on
demand, and Landlord shall have (in addition to any other right or remedy of
Landlord) the same rights and remedies in the event of the nonpayment thereof by
Tenant as in the case of default by Tenant in the payment of rental.

     22.  Attorneys' Fees. If as a result of any breach or default in the
          ---------------
performance of any of the provisions of this Lease, Landlord uses the services
of an attorney in order to secure compliance with such provisions or recover
damages therefor, or to terminate this Lease or evict Tenant, Tenant shall
reimburse Landlord upon demand for any and all attorneys' fees and expenses so
incurred by Landlord, provided that if Tenant shall be the prevailing party in
any legal action brought by Landlord against Tenant, Tenant shall be entitled to
recover for the fees of its attorneys in such amount as the court may adjudge
reasonable.

     23.  Eminent Domain. If any part of the Premises shall be taken as a result
          --------------
of the exercise of the power of eminent domain, this Lease shall terminate as to
the part of the Premises so taken as of the date of taking, and either Landlord
or Tenant shall have the right to terminate

                                      35.
<PAGE>

this Lease as to the balance of the Premises remaining after a partial taking by
written notice to the other within 30 days after such date, provided, however,
that a condition to the exercise by Tenant of such right to terminate shall be
that such partial taking shall be to such extent and nature as to substantially
and permanently handicap, impede, or impair the conduct of Tenant's business
therein. If all of the Premises are taken as a result of the exercise of the
power of eminent domain, this Lease shall terminate upon the date of taking. If
any part of the Building (other than the Premises) shall be taken as a result of
the exercise of the power of eminent domain, Landlord shall have the right to
terminate this Lease by written notice to Tenant within 30 days from the date of
such taking; in the event that Landlord does not so elect, this Lease shall
continue in full force and effect, provided that Tenant is afforded continuous
access to the Premises.

         Landlord shall be entitled to any and all compensation, damages,
income, rent, awards, or any interest therein whatsoever which may be paid or
made in connection with any exercise of the power of eminent domain, and Tenant
shall have no claim against Landlord for the value of any unexpired term of this
Lease or otherwise, except that Tenant shall be entitled to any specific award
made in favor of Tenant covering Tenant's trade fixtures and relocation
expenses. In the event of a partial taking of the Premises which does not result
in a termination of this Lease, the monthly rental thereafter to be paid shall
abate in proportion to that portion of the Premises that is rendered unusable by
Tenant in the conduct of its business.

         It is understood and agreed that the foregoing provisions of this
Section are intended to and do fully define and set forth the respective rights
and obligations of the parties in the event of a taking of the Premises or a
part thereof, including without limitation the circumstances under

                                      36.
<PAGE>

which this Lease shall or may be terminated, and the disposition of any
insurance or award, and Landlord and Tenant each expressly waives the benefit
and effect of any rights and/or obligations whether purporting to arise by law,
by governmental order, under any insurance contract, or otherwise (including the
provisions of the California Code of Civil Procedure section1265.130), which are
inconsistent with the rights and obligations set forth herein.

         For purposes hereof the "date of taking" shall be deemed to be the date
that physical possession of the property taken is delivered to the condemning
authority.

         24.  Subordination. This Lease shall be subject and subordinate at all
              -------------
times to (a) all ground or underlying leases which may hereafter be executed
affecting the Building and (b) the liens of all mortgages and deeds of trust now
or hereafter placed on or against the Building or on or against Landlord's
interest or estate therein or on or against all such ground or underlying
leases, all without the necessity of having further instruments executed on the
part of Tenant to effect such subordination; provided that if and for as long as
Tenant is not in default in the payment of rental or other sums or be otherwise
in default under the terms of this Lease, and Tenant attorns to the Landlord of
any such ground or underlying lease or to the purchaser upon foreclosure of the
lien of any mortgage or deed of trust, or, if requested, enters into a new lease
for the balance of the original or extended term hereof then remaining upon the
same terms and provisions as are in this Lease contained (which attornment or
entry into a new lease Tenant hereby agrees to do), the rights and possession of
Tenant under this Lease shall not be disturbed. Tenant agrees to execute and
deliver upon demand such further instruments evidencing such subordination of
this Lease to such ground or underlying leases, and to the liens of any such
mortgages or deeds of trust, as may be requested by Landlord and/or in such form
as is required

                                      37.
<PAGE>

by Landlord's lender (including provisions waiving as against lender claims of,
and giving to lender notice of and the right to cure, Landlord defaults under
the Lease).

     25.  No Merger. The voluntary or other surrender of this Lease by Tenant,
          ---------
or a mutual cancellation thereof, shall not work a merger, and, at the option of
Landlord, either shall operate (a) to terminate all or any existing subleases or
subtenancies under the Lease or (b) as an assignment to Landlord of any or all
such subleases and subtenancies.

     26.  Sale. If the original Landlord hereunder, or any successor owner of
          ----
the Building, shall sell or convey the Building, all liabilities and obligations
on the part of the original Landlord, or such successor owner, under this Lease
accruing thereafter shall terminate, and thereupon all such liabilities and
obligations shall be binding upon the new owner. Tenant agrees to attorn to such
new owner.

     27.  Estoppel Certificate. Tenant shall execute, acknowledge and deliver to
          --------------------
Landlord, within ten (10) days following request by Landlord a certificate
certifying (a) that this Lease is unmodified and in full force and effect (or if
there have been modifications, that this Lease is in full force and effect as
modified and stating the date and nature of each modification), (b) the date, if
any, to which rental and other sums payable hereunder have been paid, (c) that
no notice has been received by Tenant of any default which has not been cured,
except as to defaults specified in said certificate and (d) such other matters
as may be requested by Landlord or Landlord's lender. Any such certificate may
be relied upon by any prospective purchaser, mortgagee, or beneficiary under any
deed of trust on the Building or any part thereof.

                                      38.
<PAGE>

     28.  No Light, Air, or View Easement. Any diminution or shutting off of
          -------------------------------
light, air, or view by any structure which may be erected on lands adjacent to
the Building shall in no way affect this Lease or impose any liability on
Landlord.

     29.  Holding Over. If, without objection by Landlord, Tenant holds
          ------------
possession of the Premises after expiration of the term of this Lease, Tenant
shall become a tenant from month to month upon the terms, conditions and
provisions herein specified but at a monthly rental equivalent to 150 percent of
the then prevailing fair market rental as determined in good faith by the
Landlord but in no event less than the rental being paid by Tenant in the last
month of the term of this Lease, payable in advance on or before the first day
of each month. Each party shall give the other notice at least one month prior
to the date of termination of such monthly tenancy of its intention to terminate
such tenancy.

     30.  Abandonment. Tenant shall not vacate or abandon any part or all of the
          -----------
Premises. If Tenant shall vacate, abandon, or surrender the Premises, or be
dispossessed by process of law or otherwise, any personal property belonging to
Tenant and left on the Premises shall be deemed to be abandoned, at the option
of the Landlord, except such property as may be mortgaged to Landlord.

     31.  Surrender. Tenant shall at the end of the term hereof surrender to
          ---------
Landlord the Premises and all alterations, additions and improvements thereto in
the same condition as when received, ordinary wear and tear and damage by fire,
earthquake, act of God, or the elements excepted. Subject to Landlord's right to
require removal pursuant to Section 7 hereto, all improvements installed in the
Premises by Tenant, shall, without compensation to Tenant, then become
Landlord's property free and clear of all claims to or against them by Tenant or
any third

                                      39.
<PAGE>

person, and Tenant shall defend and indemnify Landlord against all liability and
loss arising from such claims or from Landlord's exercise of the rights
conferred by this Section.

     32.  Waiver. The waiver by either party of any term, agreement, condition,
          ------
or provision herein contained shall not be deemed to be a waiver of any
subsequent breach of the same or any other term, agreement, condition, or
provision herein contained, nor shall any custom or practice which may grow
between the parties in the administration of the terms hereof be construed to
waive or to lessen the right of such party to insist upon the performance by the
other party in strict accordance with said terms. The subsequent acceptance of
rental hereunder by Landlord shall not be deemed to be a waiver of any preceding
breach by Tenant of any term, agreement, condition, or provision of this Lease,
other than the failure of Tenant to pay particular rental so accepted,
regardless of Landlord's knowledge of such preceding breach at the time of
acceptance of such rental.

     33.  Notice. All notices, demands or other writings provided in this Lease
          ------
to be given or made or sent, or which may be given or made or sent by one party
to another party, shall be deemed to have been fully given or made or sent when
made in writing and upon personal delivery (whether by such party or its agent,
or by courier, or by electronic transmissions such as FAX or telex) or after 72
hours following deposit in the United States mail, registered or certified,
postage prepaid, and addressed to such party at the address specified in the
Basic Lease Information, or to such other place as such party may from time to
time designate in a notice to the other party or parties. Tenant hereby appoints
as its agent to receive the service of all dispossessory or distraint
proceedings and notices thereunder the person in charge of or occupying the
Premises at the time,

                                      40.
<PAGE>

and, if no person shall be in charge of or occupying the same, then such service
may be made by attaching the same on the main entrance of the Premises.

     34.  Complete Agreement. There are no oral agreements between Landlord and
          ------------------
Tenant affecting this Lease, and this Lease supersedes and cancels any and all
previous negotiations, arrangements, brochures, agreements, and understandings,
if any, between Landlord and Tenant or displayed by Landlord to Tenant with
respect to the subject matter of this Lease. There are no representations
between Landlord and Tenant other than those contained in this Lease, and all
reliance with respect to any representations is solely upon such
representations.

     35.  Corporate Authority. If Tenant signs as a corporation, each of the
          -------------------
persons executing this Lease on behalf of Tenant does hereby covenant and
warrant that Tenant is a duly authorized and existing corporation, that Tenant
has and is qualified to do business in California, that the corporation has full
right and authority to enter into this Lease, and that the person(s) signing on
behalf of the corporation were authorized to do so.

     36.  Miscellaneous Provisions.
          ------------------------

          (a)  The words "Landlord" and "Tenant" as used herein shall include
the plural as well as the singular.

          (b)  If there be more than one Tenant, the obligations hereunder
imposed upon Tenant shall be joint and several.

          (c)  Time is of the essence of this Lease and each and all of its
provisions.

          (d)  Submission of this instrument for examination or signature by
Tenant does not constitute a reservation of or option for lease, and it is not
effective as a lease or otherwise until execution and delivery by both Landlord
and Tenant.

                                      41.
<PAGE>

          (e)  The agreements, conditions and provisions herein contained shall,
subject to the provisions as to assignment, apply to and bind the heirs,
executors, administrators, successors and assigns of the parties hereto.

          (f)  If any provision of this Lease shall be determined to be illegal
or unenforceable, such determination shall not affect any other provision of
this Lease and all such other provisions shall remain in full force and effect.

          (g)  This Lease shall be governed by and construed pursuant to the
laws of the State of California.

          (h)  All remedies hereinbefore and hereafter conferred upon Landlord
shall be deemed cumulative and no one shall be exclusive of the other, or shall
in any way limit the availability to Landlord of any other remedy conferred by
law, whether or not specifically conferred by the provisions of this Lease.

          (i)  All indemnities of Tenant contained in this Lease shall survive
the expiration or other termination hereof with respect to any act, condition or
event which is the subject matter of such indemnity and which occurs prior to
such expiration or other termination.

          (j)  The parties acknowledge and agree that each party has reviewed
and revised, and has been provided the opportunity of its respective counsel to
review and revise, this Lease, and no rule of construction to the effect that
any ambiguities are to be resolved against the drafting party shall be employed
in the interpretation or construction of this Lease, or any amendments or
exhibits thereto, or any other document executed and delivered by either party
in connection therewith.

                                      42.
<PAGE>

     37.  Exhibits. The exhibit(s) and addendum, if any, specified in any of the
          --------
Sections of this Lease are attached to this Lease and by this reference made a
part hereof.

     38.  Security Deposit. Tenant has deposited with Landlord the sum specified
          ----------------
in the Basic Lease Information ("Deposit"). The Deposit shall be held by
Landlord as security for the faithful performance by Tenant of all of the
provisions of this Lease to be performed or observed by Tenant. If Tenant fails
to pay rent or other charges due hereunder, or otherwise defaults with respect
to any provision of this Lease, Landlord may use, apply or retain all or any
portion of the Deposit for the payment of any rent or other charge in default or
for the payment of any other sum to which Landlord may become obligated by
reason of Tenant's default or to compensate Landlord for any loss or damage
which Landlord may suffer thereby. If Landlord so uses or applies all or any
portion of the Deposit, Tenant, within 10 days after demand therefor, shall
deposit cash with Landlord in an amount sufficient to restore the Deposit to the
full amount thereof, and Tenant's failure to do so shall be a material breach of
this Lease. Landlord shall not be required to keep the Deposit separate from its
general accounts. If Tenant performs all of Tenant's obligations hereunder, the
Deposit, or so much thereof as has not theretofore been applied by Landlord,
shall be returned, without payment of interest or other increment for its use,
to Tenant (or, at Landlord's option, to the last assignee, if any, of Tenant's
interest hereunder) at the expiration of the term hereof, and after Tenant has
vacated the Premises. No trust relationship is created herein between Landlord
and Tenant with respect to the Deposit.

     39.  Brokerage. Each party warrants and represents to the other that such
          ---------
party has not retained the services of any real estate broker, finder or any
other person whose services would form the basis for any claim for any
commission or fee in connection with this Lease or the

                                      43.
<PAGE>

transactions contemplated hereby except for (a) real estate brokerage services
rendered to Land-lord by Grubb & Ellis Company, the commissions earned with
respect to which Landlord shall pay to such broker pursuant to separate
agreement between Landlord and such broker, and (b) such real estate brokerage
services as may have been rendered to Tenant for which Landlord is to have no
liability. Each party agrees to save, defend, indemnify and hold the other party
free and harmless from any breach of its warranty and representation as set
forth in the preceding sentence, including the other party's attorneys fees.

     40.  Limitation of Liability. With the exception of actions arising from
          -----------------------
Landlord's fraud, bad faith or willful misconduct, any liability of Landlord
under this Lease shall be limited to Landlord's interest in the Building and the
parcel of real property on which the Building is located, and any appurtenant
rights thereto.

     41.  Parking Spaces. Landlord shall provide to Tenant two (2) parking
           --------------
spaces in the garage of the Building for the term of the Lease. Tenant shall use
such parking spaces at its sole risk and liability, and no bailment shall be
created.

                                      44.

         IN WITNESS WHEREOF, the parties have executed this Lease as of the date
set forth in the Basic Lease Information.

     1.   General. Landlord shall install tenant improvements in the Premises,

as provided in paragraphs 2 through 5, inclusive, below. Such improvements shall
include distribution of the heating, ventilating and air conditioning system,

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

     THIS LEASE, dated effective as of the date set forth in the Basic Lease

the terms, covenants, agreements and conditions hereinafter set forth, to each
and all of which Landlord and Tenant hereby mutually agree.

     2.   Term; Improvements.
          ------------------

          (a)  Term. The term of this Lease shall commence and, unless sooner
               ----
terminated as hereinafter provided, shall end on the dates specified in the
Basic Lease Information. If Landlord, for any reason whatsoever, cannot deliver
possession of the Premises to Tenant at the commencement of the term, this Lease
shall not be void or voidable, the term of this Lease shall not be extended by
such delay, and the Landlord shall not be liable to Tenant for any loss or
damage resulting therefrom, but in that event, subject to any contrary
provisions in Exhibit B attached hereto, (i) commencement of the term shall be
deferred and the

                                       1.
<PAGE>

date on which rental commences shall be deferred for the period of such delay
and (ii) the term of the Lease shall be reduced by the number of days of such
delay.

          (b)  Improvements. The Premises are leased to Tenant in their present
               ------------
"as-is" condition, except that Landlord shall construct or install in the
Premises the improvements to be constructed or installed by Landlord pursuant to
the provisions of Exhibit B, and the costs for such improvements shall be borne
as provided in Exhibit B. Landlord's architect and Tenant shall conduct a joint
inspection of the Premises following substantial completion of such improvements
and shall prepare a joint punchlist of items to be completed. Landlord shall
complete such joint punchlist items within 30 days following preparation
thereof.

     3.   Rental. Tenant shall pay to Landlord throughout the term of this Lease
          ------
the following sums as rental for the Premises:

          (a)  Base Rent. The monthly Base Rent payable during the term of the
               ---------
Lease shall be the sum specified in the Basic Lease Information as the Base Rent
subject to the further provisions hereof.

          (b)  Additional Rent on Account of Increases in Operating Expenses. In
               -------------------------------------------------------------
addition to Base Rent, Tenant, subject to Section 3(d), shall pay to Landlord as
additional rent with respect to each calendar year of the term of this Lease or
portion thereof occurring subsequent to October 1, 1993 Tenant's percentage
share (as specified in the Basic Lease Information) of

                                       2.
<PAGE>

the total dollar increase, if any, in Operating Expenses paid or incurred by
Landlord in such subsequent calendar year or portion thereof over the Base Year
Operating Expenses. For purposes hereof, "Operating Expenses" shall mean (i) all
direct and indirect costs of management, operation and maintenance of the
Building (including rentable areas occupied by Landlord) and including, without
limiting the foregoing: wages, salaries, employee benefits, and payroll burden
of personnel engaged in management, operation and maintenance of the Building,
Building office rent or rental value, power, heat, light, steam, air
conditioning, gas, water, garbage, sewage and waste disposal and other
utilities, equipment, tools, materials and supplies, maintenance and repairs,
insurance, license, permit and inspection fees, janitorial services, maintenance
contracts and general services, and depreciation on personal property, costs of
compliance with environmental laws (including costs of monitoring and tests),
and (ii) the cost of any capital improvements made to the Building by Landlord
after the Base Year for Operating Expenses Increases that (A) reduce Operating
Expenses or that reduce or conserve the amount of utilities consumed (e.g.,
electricity, gas or other fuels) such cost of such capital improvements to be
included to the extent of the amount of the actual cost savings realized, or (B)
are required under any governmental law or regulation that was not applicable to
the Building at the time this Lease was entered into, such cost or allocable
portion thereof to be amortized over such reasonable

                                       3.
<PAGE>

period as Landlord shall determine together with interest on the unamortized
balance at the rate of 10 percent per year or such higher rate as may have been
paid by Landlord on funds borrowed for the purpose of constructing such capital
improvements; provided, however that Operating Expenses shall not include
              --------  -------
Property Taxes, depreciation on the Building other than depreciation on personal
property, costs of tenants' improvements, interest, capital items other than
those referred to in clause (ii) above, and payments on debt (principal or
interest). Actual Operating Expenses for both the Base Year and each subsequent
year of the term of this Lease shall be adjusted to equal Landlord's reasonable
estimate of Operating Expenses had the total rentable area of the Building been
occupied for both years. The determination of the costs of management,
operation, and maintenance of the Building and the costs of the capital
improvements referred to in clause (ii) above shall be in accordance with
generally accepted accounting principles consistently applied.

          (c)  Additional Rent on Account of Increases in Property Taxes. In
               ---------------------------------------------------------
addition to Base Rent, Tenant, subject to Section 3(d), shall pay to Landlord as
additional rent with respect to each calendar year of the term of this Lease or
portion thereof occurring subsequent to October 1, 1993 Tenant's percentage
share (as specified in the Basic Lease Information) of the total dollar
increase, if any, in Property Taxes paid or incurred by Landlord in such
subsequent calendar year or portion

                                       4.
<PAGE>

thereof over the Base Year Property Taxes. For purposes hereof, "Property Taxes"
shall mean all real property taxes, assessments (general or special), property
tax reassessments caused by a change in ownership of the Building or the
Premises and all other taxes (including any tax levied wholly or partly in lieu
thereof) levied against the Building (or this Lease, the occupancy of Tenant,
the sums payable by Tenant hereunder, or in any manner relative to the subject
matter hereof), excluding only taxes covered by Section 6 hereof and federal and
California income and death taxes imposed with respect to Landlord. For purposes
hereof, "taxes" is meant to be interpreted in its most comprehensive sense and
to include any impost, levy or the like levied by any governmental jurisdiction;
and without limiting the generality of the foregoing, "taxes" shall include any
tax, fee, excise, levy or other impost imposed by the United States, the State
of California or any political subdivision of the State (including any county,
city, city and county, public corporation, district or any other political
entity or public corporation thereof), however described (including any so-
called value-added tax) as a direct substitution in whole or in part for, or in
addition to, real property taxes and assessments.

          (d)  Procedure. The additional rent provided under Sections 3(b) and
               ---------
3(c) above shall be paid in accordance with the following procedures:

               (i)  As soon as is practicable following the first anniversary of
this Lease and the end of each calendar year

                                       5.
<PAGE>

thereafter occurring during the term of this Lease, Landlord shall give Tenant
written notice of its estimate of any increased amounts payable under Section
3(b) and/or 3(c). On or before the first day of the calendar month next
following such notice, Tenant shall pay to Landlord that portion of the
estimated amounts that already shall have accrued and thereafter on or before
the first day of each succeeding calendar month shall pay a ratable portion of
the balance remaining over the relevant period covered. If for any reason such
notice is not given as provided above, Tenant shall continue to pay on the basis
of the then applicable rental until the month after such notice is given. If at
any time or times Landlord determines that the increased amounts payable under
Sections 3(b) and/or 3(c) above will vary from its estimate by more than 10
percent, Landlord shall, by notice to Tenant, revise its estimate for such year,
and subsequent payments by Tenant for such year shall be based upon such revised
estimate.

               (ii) Within 90 days after the close of each respective calendar
year during the term of this Lease subsequent to the Base Year (or as soon after
such 90-day period as practicable), Landlord shall deliver to Tenant a statement
of the adjustments to be made pursuant to Sections 3(b) and/or 3(c) above for
such calendar year which statement shall be audited and shall be prepared in
accordance with generally accepted accounting principles, and such statement
shall be final and binding upon Landlord and Tenant. If on the basis of such

                                       6.
<PAGE>

statement Tenant owes an amount that is less than the estimated payments for
such year previously made by Tenant, Landlord shall refund such excess to Tenant
within 30 days of the delivery of such statement. If on the basis of the
statement Tenant owes an amount that is more than the estimated payments for
such year previously made by Tenant, Tenant shall pay the deficiency to Landlord
within 30 days after delivery of the statement.

               (iii) If the date of the first anniversary of this Lease is a day
other than the first day of a calendar year, the amount of adjustment to be made
pursuant to Sections 3(b) and/or 3(c) above that is applicable to the calendar
year in which such first anniversary occurs shall be prorated on the basis that
the number of days from the first anniversary date to and including the last day
of such calendar year bears to 365.

               (iv)  If this Lease shall terminate on a day other than the last
day of a calendar year, the amount of adjustment to be made pursuant to Sections
3(b) and/or 3(c) above that is applicable to the calendar year in which such
termination occurs shall be prorated on the basis that the number of days from
the commencement of such year to and including the termination date bears to
365. The termination of this Lease shall not affect the obligations of Landlord
and Tenant pursuant to subparagraph (ii) of this Section 3(d) to be performed
after such termination.

          (e)  Rental Commencement. Base Rent shall be paid to Landlord (i) upon
               -------------------
the execution of this Lease for the first full month of the term of this Lease
for which rent is payable as set

                                       7.
<PAGE>

forth in the Basic Lease Information (as the same may be deferred pursuant to
Section 2(a) hereof), and (ii) with respect to the second full month and each
successive calendar month thereafter for which rent is payable, on or before the
first day of each such month. If this Lease commences on other than the first
day of a calendar month or ends on other than the last day of a calendar month,
the second and last installments of rent shall be pro-rated for the partial
months involved.

          (f)  No Deduction or Offset; Interest. All rental and all other sums
               --------------------------------
due and payable by Tenant to Landlord under any of the provisions of this Lease
shall be paid to Landlord, without abatement, deduction, offset, prior notice or
demand, in lawful money of the United States at Landlord's address for notices
or to such other person or at such other place as Landlord, from time to time,
may designate in writing. Tenant acknowledges that late payment by Tenant to
Landlord of rental or such sums will cause Landlord to incur costs not
contemplated by this Lease, the exact amount of such costs being extremely
difficult and impracticable to fix. Such costs include, without limitation,
processing and accounting charges, and late charges that may be imposed on
Landlord by the terms of any encumbrance and note secured by any encumbrance
covering the Building and/or the Premises. Therefore, if any installment of
rental or any other sum due and payable by Tenant to Landlord is not paid to and
received by Landlord within 10 days of the due date thereof (or, if Landlord has
notified Tenant in writing on two occasions

                                       8.
<PAGE>

during the 12 months preceding the due date that Tenant has failed to pay rent
or any other sum on the due date thereof, then if Tenant fails to pay rent or
other sum on the due date thereof):

               (i)  Tenant shall pay to Landlord an additional sum of five
percent (5%) of the overdue amount as a late charge. The parties agree that this
late charge represents a fair and reasonable estimate of the costs that Landlord
will incur by reason of late payment by Tenant; and

               (ii) the sums due and payable shall bear interest from date due
until paid at the highest rate legally permitted by applicable law.

     Acceptance of any late charge or interest shall not constitute a waiver of
Tenant's default on the overdue amount, or prevent Landlord from exercising any
of the other rights and remedies available to Landlord.

     4.   Use. The Premises shall be used for general office purposes and no
          ---
others. Tenant shall neither do nor permit to be done in or about the Premises,
nor bring or permit to be brought or kept therein, anything which is prohibited
by or will in any way conflict with any law, statute, ordinance or governmental
rule or regulation now in force or which may hereafter be enacted or
promulgated, or which now or hereafter is prohibited by any insurance policy
carried by Landlord, or will in any way increase the existing rate of or affect
any fire or any other insurance upon the Building or any of its contents, or
cause a cancellation

                                       9.
<PAGE>

of any insurance policy covering the Building or any part thereof or any of its
contents. Tenant, in its own respect and in respect of its agents, servants and
invitees, shall neither do nor permit anything to be done in or about the
Premises or the Building or any part thereof which will in any way obstruct or
interfere with the rights of other tenants of the Building (including any noise
audible or any odor or vibrations observable from outside the Premises), or
injure or annoy them, or use or allow the Premises or the Building or any part
thereof to be used for any improper, unlawful or objectionable purpose, nor
shall Tenant cause, maintain or permit any nuisance in, on or about the Premises
or the Building or any portion thereof, or commit or suffer to be committed any
waste or damage in or about the Premises or the Building or any portion thereof.
Tenant shall not permit any materials to be placed or stored in the common areas
of the Building and shall not permit debris to be placed therein, except in
appropriate receptacles provided therefor. Tenant, its agents, servants and
invitees shall have the right on a 24 hour per day - seven day per week basis
during the term hereof, subject to compliance with Landlord's security
procedures, to the (a) non-exclusive use of the entrance lobby of the Building,
its passenger and freight elevators, and the common area of the floor of the
Building in which the Premises are located, for purposes of ingress to and
egress from the Premises, and (b) the restrooms located on the floor of the
Building in which the Premises are located, and (c) the exclusive use of the

                                      10.
<PAGE>

Premises. The provisions of Sections 11 and 12 of this Lease shall apply to all
such areas. Tenant shall not use any portion of the Building (including, without
limitation, the Building roof or portions of the Building leased to other
tenants) other than the Premises, excepting only as set forth in the preceding
sentence and such other portions of the Building as are necessary for fire and
other emergency ingress and egress purposes in accordance with applicable law.
Tenant shall not place any equipment in or otherwise utilize the Premises in a
manner that would exceed the floor load limits specified by Landlord.

     5.   Services.
          ---------

          (a)  Reasonable Services. Landlord (subject to the further provisions
               -------------------
of this Section 5) shall furnish the Premises:

               (i)   during the period from 7 a.m. to 6 p.m., Monday through
Friday (except holidays), or such shorter period as may be prescribed by any
applicable policies or regulations adopted by any utility or governmental
agency, with heat and air conditioning in such amounts and at such temperatures
as Landlord reasonably determines are required for purposes of human comfort;

               (ii)  a reasonable amount of water;

               (iii) electricity for lighting and the operation of office
machines and any equipment installed pursuant to Exhibit B hereof, for which
purposes Landlord will provide Tenant with an electric allowance of 11,208
kilowatt-hours per month. Tenant shall pay to Landlord upon demand for all
electric power Landlord determines is consumed by Tenant in excess of such

                                      11.
<PAGE>

allowance. The determination of the amount of Tenant's electric power
consumption shall be made by Landlord in good faith and shall be final, binding
and conclusive, provided that, if Tenant so elects, Landlord shall install at
Tenant's expense a separate electric meter to measure the electrical power
actually consumed by Tenant;

               (iv)  non-attended, or attended, at Landlord's election, elevator
service, and

               (v)   daily (one shift) janitor service Monday through Friday
(except holidays) which shall be provided by Landlord in the manner that such
service is customarily furnished in comparable office buildings in the area.

     Tenant shall notify Landlord within five (5) days following request thereby
of the nature and quantity of all Tenant's equipment and other items using
electricity in the Premises.

     Landlord shall not be in default hereunder or be liable for any damage
directly or indirectly resulting from, nor shall the rental herein reserved be
abated by reason of, (i) failure to furnish or delay in furnishing any such
services when such failure or delay is caused by accident or any condition
beyond the control of Landlord or by the making of repairs or improvements to
the Premises or to the Building (including the Building systems), or (ii) the
limitation, curtailment, rationing or restrictions on use of or the failure of
the supply by the relevant utility to Tenant of, water, electricity, gas, or any
other form of utility services serving the Premises or the

                                      12.
<PAGE>

Building. Tenant expressly acknowledges that all utility services are provided
by the relevant utility involved, and Landlord is to have no responsibility for
the amount or quality of utility services provided, including without
limitation, the improper operation of Tenant's equipment utilizing the same.

          (b)  Excess Electricity. Tenant, without the prior written consent of
               ------------------
Landlord, shall not use any apparatus or device in the Premises which alone or
collectively uses electricity in excess of the capacity of the electrical
circuits to the Premises installed pursuant to Exhibit B hereof, nor connect
with electric current, except through existing electrical outlets in the
Premises, any apparatus or device, for the purposes of using electric current.
If Tenant shall require electric current in excess of the capacity of the
electrical circuits to the Premises installed pursuant to Exhibit B hereof,
Tenant shall first obtain Landlord's consent to the installation of such
increased electrical capacity in accordance with the provisions of Section 7
hereof. Tenant agrees to pay Landlord for such excess electric current consumed
in excess of the allowance provided in Section 5(a) above.

          (c)  Excess Water. Tenant shall not use water in excess of that
               ------------
furnished by Landlord for use of the Premises as general office space or connect
any apparatus or device for the purpose of using water. If Tenant shall require
water in excess of that usually furnished or supplied for use of the Premises as
general office space, Tenant shall first procure the written

                                      13.
<PAGE>

consent of Landlord to the use thereof. Landlord, as a condition of Landlord's
consent, may cause a water meter to be installed, so as to measure the amount of
excess water used. The cost of any such meter and of installation, maintenance
and repair thereof shall be paid by Tenant, and Tenant agrees to pay to Landlord
promptly upon demand thereof by Landlord for all such excess water so used.
Unless and until Landlord installs such separate meter, Tenant shall pay to
Landlord promptly upon demand Landlord's good faith estimate of the cost of the
excess of the amount of water used by Tenant over that usually furnished or
supplied by Landlord for use of the Premises as general office space, and
Landlord's estimate of such excess amounts, based upon the independent judgment
of Landlord's engineer, the manufacturer of the equipment involved, or the
utility providing the service, shall be final, binding, and conclusive upon
Tenant.

          (d)  Excess Air-Conditioning. Tenant (except as otherwise provided in
               -----------------------
Exhibit B) shall not use any apparatus or device in the Premises that will
increase the amount of air conditioning furnished by Landlord for general office
space.

     6.   Taxes Payable by Tenant. In addition to the monthly rental and other
          -----------------------
charges that are payable by Tenant hereunder, Tenant shall reimburse Landlord
upon demand for any and all taxes payable by Landlord whether or not now
customary or within the contemplation of the parties hereto which are upon,
measured by, or reasonably attributable to the cost or value of Tenant's
equipment, furniture, fixtures, and other personal property

                                      14.
<PAGE>

located in the Premises or by the cost or value of any leasehold improvements
made in or to the Premises by or for Tenant, other than tenant improvements made
and paid for by Landlord hereunder, regardless of whether title to such
improvements shall be in Tenant or Landlord.

     7.  Alterations, Additions or Improvements. Except for the initial
         --------------------------------------
improvement of the Premises pursuant to Exhibit B, which shall be governed by
the provisions of Exhibit B, Tenant shall not make or suffer to be made any
alterations, additions, or improvements to or of the Premises or any part
thereof, or attach any fixtures or equipment thereto, without Landlord's prior
written consent. All such alterations, additions or improvements shall become
Landlord's property immediately and, at the end of the term hereof, shall remain
on the Premises without compensation to Tenant unless Landlord elects by notice
to Tenant given at the time of Landlord's consent to have Tenant remove the
same, in which event Tenant shall promptly remove such alterations, additions or
improvements, repair any damage to the Premises, and restore the Premises to
their condition prior to the installation of such alterations, additions or
improvements.

     Tenant at its expense shall obtain any and all permits and consents of
applicable governmental authorities in respect of such alterations, additions,
and improvements and shall comply with the requirements of all governmental
authorities in connection therewith, including all building codes; and Tenant
shall be liable to Landlord and shall reimburse Landlord for the

                                      15.
<PAGE>

costs of any improvements to the Building (whether or not within the Premises)
which may be required by governmental authority as a consequence of Tenant's
alterations, additions and improvements.

     All alterations made by Tenant with the prior written consent of Landlord
shall be effected through the use of contractors approved by Landlord who shall
furnish to Landlord upon demand such completion bonds and labor and material
bonds as Landlord may require so as to assure completion of such alterations,
additions or improvements on a lien-free basis (and the furnishing of the same
shall not relieve Tenant of its obligation under Section 8 hereof).

     8.   Liens. Tenant shall keep the Premises and the Building free and clear
          -----
of and from any and all mechanics', materialmen's and other liens for work or
labor done, services performed and for materials used or furnished in or about
the Premises by or on behalf of Tenant. Tenant at all times shall pay and
discharge, promptly and fully, any and all claims upon which any such lien may
or could be based, provided that Tenant in good faith may contest any such lien
if Tenant obtains and records a statutory lien release bond the effect of which
is that the lien is expunged from Landlord's title as a matter of law. Tenant
shall save, defend, indemnify and hold Landlord, the Premises and the Building
free and harmless of and from any and all such liens or claims of liens or suits
or other proceedings pertaining thereto.

                                      16.

     9.   Repairs. By entry hereunder, Tenant accepts the Premises as being in
          -------
the condition in which Landlord is obligated to deliver the Premises, subject
only to the work to be performed by Landlord pursuant to Section 2(b) and
Exhibit B. Tenant, at all times during the term hereof and at Tenant's sole cost
and expense, shall keep the Premises and every part thereof in good condition
and repair, excepting (a) ordinary wear and tear, and (b) damage due to casualty
with respect to which the provisions of Section 10 and 12 shall apply. Tenant
hereby waives all right to make repairs at the expense of Landlord or in lieu
thereof to vacate the Premises as provided by California Civil Code Section 1941
and 1942 or any other law, statute or ordinance now or hereafter in effect.
Landlord has no obligation and has made no promise to alter, remodel, improve,
repair, decorate, or paint the Premises or any part thereof except as
specifically herein set forth in Exhibit B. The maintenance of the Building
structure, Building systems, and common areas of the Building are the sole
responsibility of the Landlord. Except as specifically set forth herein,
Landlord has not made any representations respecting the condition of the
Premises to Tenant.

     10.  Destruction or Damage.
          ---------------------

          (a)  Damage. If the Premises and/or the portion of the Building
               ------
necessary for Tenant's occupancy are damaged by fire, earthquake, act of God,
the elements, or other casualty, Landlord shall forthwith repair the same,
subject to the provisions of this Section hereinafter set forth, if such
repairs, in

                                      17.
<PAGE>

Landlord's opinion, can be made within 90 days following the issuance of any
building permit required by relevant governmental authority (the "Rebuilding
Period"). This Lease shall remain in full force and effect except that, if such
damage is not the result of the negligence or willful misconduct of Tenant or
Tenant's employees or invitees, a proportional abatement of rental (based upon
square footage) shall be allowed Tenant for such part of the Premises as shall
be rendered unusable by Tenant in the conduct of its business during the time
such part is so unusable. Landlord's determination that such repair may be made
within the Rebuilding Period shall not obligate Landlord to complete the same
within such period. For purposes of this Section 10, "repairs" shall include all
repair and restorative work Landlord in Landlord's good faith but nevertheless
sole discretion deems advisable, including without limitation, all work and
improvements Landlord deems advisable to improve the condition and quality of
the Building, whether in the form of government mandated building code upgrades
or otherwise.

          (b)  Repair. If such repairs, in Landlord's opinion, cannot be made
               ------
within the Rebuilding Period, Landlord shall elect, by notice to Tenant within
30 days after the date of such fire or other casualty: (i) to repair or restore
such damage, in which event this Lease shall continue in full force and effect
(except that the rent shall be partially abated as hereinabove provided) and
Landlord shall repair and restore such damage with reasonable diligence, or (ii)
to terminate this Lease, in which

                                      18.
<PAGE>

event this Lease shall terminate as of the date of such fire or other casualty.

          (c)  Waiver. Tenant waives California Civil Code Sections 1932(2) and
               ------
1933(4) providing for termination of hiring upon destruction of the thing hired.

          (d)  Costs of Repair. If the Premises are to be repaired under this
               ---------------
Section, Landlord (subject to the provisions of Section 12(b) hereof) shall
repair at its cost any injury or damage to the Building itself and the tenant
improvements in the Premises paid for by Landlord hereunder. Tenant shall repair
and pay the cost of repairing Tenant's alterations, Tenant's improvements,
Tenant's trade fixtures, Tenant's personal property and any other tenant
improvements in the Premises and shall be responsible for carrying such casualty
insurance as it deems appropriate with respect to such other tenant
improvements.

          (e)  Tenant's Right to Terminate Lease. If the Premises are not
               ---------------------------------
restored within one hundred eighty (180) days after the date of damage or
destruction, Tenant shall have the right to terminate this Lease.

     11.  Insurance; Waiver of Subrogation.
          --------------------------------

          (a)  Insurance. Tenant, at Tenant's expense, shall maintain in full
               ---------
force during the term hereof a policy or policies of comprehensive broad form
general public liability insurance insuring against claims and liability for
personal injury, death and property damage arising in or about the Premises, the
Building and adjoining areas or ways, with a

                                      19.
<PAGE>

carrier or carriers acceptable to Landlord, and which carrier or carriers in any
event shall have a rating of not less than A Plus XIII by Best's Insurance
Guide. The liability under such insurance shall not be less than $1,000,000
combined single limit bodily injury and property damage. Such policy or policies
of insurance shall (a) name Landlord and Landlord's lender as additional
insureds, (b) be nonassessable, primary and noncontributory with any policies
carried by Landlord, and (c) provide that the same may not be cancelled or
materially amended except upon 30 days prior written notice to Landlord. Tenant
at all times shall maintain with Landlord a current certificate or certificates
of said policy or policies. The amount of insurance coverage provided for in
this Section shall be increased from time to time during the term hereof upon
demand of Landlord to the extent reasonably required by circumstances then
existing (including, but not limited to increases in the cost of living as
reflected in the Consumer Price Index published by the U.S. Department of Labor
and increases in personal injury and wrongful death judgments or awards in the
City and County of San Francisco).

          (b)  Subrogation. To the extent available without material incremental
               -----------
premium, each party shall obtain from its insurers under all policies of
property insurance maintained by such party at any time during the term hereof
insuring or covering the Premises, the Building or any portion thereof or
operations therein, a waiver of all rights of subrogation which

                                      20.
<PAGE>

the insurer might have against the other party, and each party shall indemnify
the other party against any loss or expense, including reasonable attorneys'
fees, resulting from the failure to obtain such waiver to the extent the same is
so available.

     12.  Waiver; Indemnity.
          -----------------

          (a)  Tenant covenants and agrees that Landlord shall not at any time
after the date hereof or to any extent whatsoever be liable, responsible or in
anywise accountable for, and Tenant waives and releases any claim (including any
claim for contractual or implied indemnity) against Landlord, for Losses
(hereinafter defined) which at any time after the date hereof may be suffered or
sustained by:

          thereto, and which Losses are caused in whole or in part by any act or
          omission (whether negligent, non-negligent or otherwise) of Tenant,
          its agents, servants and invitees;

and whether in case of either clause (i) and/or (ii) such Losses shall be caused
- ----------
in part by any act, omission or negligence of Landlord, its agents or servants,
except to the extent caused by the grossly negligent or willful act or omission
of Landlord, its agents or employees.

                                      21.
<PAGE>

          (b)  In addition to, and not in limitation of (a) above, Tenant shall
forever indemnify, defend, hold and save Landlord and Landlord's Lender free and
harmless of, from and against any and all Losses caused in whole or in part by
any act or omission (whether negligent, non-negligent, or otherwise) of Tenant,
its agents servants and invitees and suffered or sustained by:

               (i)  Landlord; and/or

               (ii) any third person who asserts a claim against Landlord on
          account thereof;

and whether in case of either clause (i) and/or (ii) such Losses shall be caused
- -----------
in part by any act, omission or negligence of Landlord, its agents or servants,
except to the extent caused by the grossly negligent or willful act or omission
of Landlord, its agents or employees. The foregoing indemnity obligation of
Tenant shall include reasonable attorneys' fees, investigation costs, and all
other reasonable costs and expenses incurred by Landlord from the first notice
that any claim or demand is to be made or may be made.

          (c)  For purposes hereof "Losses" shall mean any and all losses,
damages, costs and expenses, direct and indirect, actual and consequential, on
account of injury to or death of persons, or loss of or damage to property, of
any kind or nature, including without limitation, loss, injury, death or damage
due to criminal act by third persons.

                                      22.
<PAGE>

          (d)  The provisions of this Section 12 shall survive the termination
of this Lease with respect to any Losses occurring prior to such termination.
The insurance policy or policies required pursuant to the provisions of Section
11(a) by their terms shall cover the indemnity obligations of Tenant under
Section 12(b), except to the extent that any such obligation arises from
allegations of the willful misconduct of Tenant, its servants or its agents.

any court of competent jurisdiction or the admission by Tenant (excluding from
the term "admission" any settlement or consent decree which by its terms does
not admit Tenant's liability) in any action or

                                      23.

     14.  Assignment and Subletting.
          -------------------------

          (a)  Assignment and Subletting. Except as expressly permitted pursuant
               -------------------------
to this Section, Tenant shall not, without the prior written consent of
Landlord, assign this Lease, or any interest herein, or sublet the Premises, or
any part thereof, or permit the use or occupancy of the Premises (or any right
or privilege appurtenant thereto) by any party other than Tenant. For purposes
hereof, "assignment" shall include any proposed disposition or transfer,
voluntary or involuntary, or hypothecation; and where Tenant is a (i)
partnership, "assignment" shall include a transfer of 25% or more of the equity
interest therein (other than to an existing equity holder) or (ii) a corporation
"assignment" shall include (except with respect to a corporation whose stock is
publicly traded) any (A) merger, consolidation or other reorganization
(involving the equity securities of Tenant) of Tenant, (B) liquidation,
dissolution or disposition of all or substantially all of the assets of Tenant
or (C) change in ownership of 40% or more of the equity interest therein (other

such consent of Landlord shall be void and shall, at the option of Landlord,
terminate this Lease. This Lease shall not, nor shall any interest herein, be
transferable or assignable as to the interest of Tenant by operation of law
without the written consent of Landlord.

     Landlord's consent to any assignment or subletting of all or any part of
the Premises shall not be unreasonably withheld or

                                      27.
<PAGE>

delayed. Without limiting the other instances in which it may be reasonable for
Landlord to withhold its consent to an assignment or subletting, Landlord and
Tenant acknowledge that it shall be reasonable for Landlord to withhold its
consent from a proposed assignment or subletting in the following instances:

               (i)   If Landlord determines in its good faith but nevertheless
sole discretion that the use of the Premises by the proposed assignee or
sublessee would be in violation of Section 4 of this Lease;

               (ii)  If Landlord determines in its good faith but nevertheless
sole discretion that the financial worth of the proposed assignee or sublessee
does not meet the credit standards applied by Landlord for other tenants under
leases with comparable terms;

               (iii) If Landlord determines in its good faith but nevertheless
sole discretion that the proposed assignee or sublessee does not have a
favorable reputation as a tenant of property;

               (iv)  If Landlord has received from any prior lessor to the
proposed assignee or subtenant a negative report concerning such prior lessor's
experience with the proposed assignee or subtenant;

               (v)   If Landlord has experienced previous defaults by or is in
litigation with the proposed assignee or subtenant;

               (vi)  If the use of the Premises by the proposed assignee or
subtenant will violate any applicable law, ordinance

                                      28.
<PAGE>

or regulation, or any use permit issued for the use and occupancy of the
Premises.

          (b)  Information; Landlord's Options. If at any time, or from time to
               -------------------------------
time, during the term of this Lease, Tenant desires to assign, sublet or permit
the occupancy or use by another of all or any part of the Premises, Tenant shall
give notice to Landlord setting forth the following: (i) the name, address, and
legal composition of the proposed sublessee, occupier or user; (ii) the nature
of the business proposed to be carried on in the Premises (including proposed
number of employees to be located in the Premises, the proposed equipment to be
used therein, proposed floor loads and proposed electrical loads); (iii) a copy
of the proposed assignment or sublease agreement; and (iv) any other
documentation or information reasonably requested by Landlord, including
financial information covering the proposed assignee, sublessee, occupier or
user with respect to such proposed subletting. All such information may be
considered by Landlord in making Landlord's permitted determinations hereunder,
including the granting or withholding of consent in respect of a proposed
assignment or subletting. Such notice, once so given, shall not be withdrawn or
rescinded by Tenant. Landlord shall have the options, exercisable by notice
given to Tenant within 10 days after Tenant's notice is given, to do the
following:

               (i)  In the case of a proposed subletting, Landlord may sublet
from Tenant such space at the rental and

                                      29.
<PAGE>

other terms set forth in this Lease, prorated where appropriate to reflect
obligations allocable to that portion of the Premises to be sublet, unless the
rental to be paid by the proposed sublessee is lower than the rental, as so
prorated, payable under the Lease, in which event such lower rental shall be
payable by Landlord to Tenant, or

               (ii) In the case of either a proposed assignment or subletting,
Landlord may terminate this Lease as to that part or all of the Premises
proposed to be assigned or sublet, and in the case of termination as to a
portion of the Premises, Tenant's obligations under the Lease as to the balance
of the Premises remaining shall be proportionately reduced.

     If Landlord sublets such space or terminates the Lease as to such space, in
each instance leaving a portion of the Premises occupied by Tenant, Tenant shall
provide Landlord without charge reasonable and appropriate access to such space
and reasonable use of any common areas and facilities appurtenant thereto. For
purposes hereof, "common area" shall mean the total area on a floor consisting
of rest rooms, janitor, telephone and electrical closets, mechanical areas, and
public corridors providing access to tenant space on such floor, but excluding
public stairs, elevator shafts and pipeshafts, together with the enclosing walls
thereof.

          (c)  Assignment or Subletting Conditions. Subject to (i) the other
               ------------------------ ----------
provisions of this Section 14 and (ii) Landlord's consent, which shall not be
unreasonably withheld or delayed,

                                      30.
<PAGE>

Tenant may assign or sublet such space to any third party on the following
conditions:

               (i)   In the case of a sublease, the same shall be subject and
subordinate to all of the provisions, terms and conditions of this Lease,

               (ii)  No assignment or sublease shall be valid and no assignee or
sublessee shall take possession of the Premises assigned or subleased until an
executed counterpart of such assignment or sublease, in form and substance
satisfactory to Landlord, shall have been delivered to Landlord, and Landlord
shall have expressly consented thereto in writing,

               (iii) No assignee or sublessee shall have a further right to
assign or sublet,

               (iv)  An amount equal to 50% of all sums or other economic
consideration received by Tenant as a result of such assignment or subletting,
however denominated (whether as consideration for the assignment, rentals under
a sublease, or otherwise), which exceed in aggregate the total sums which Tenant
(or Tenant's assignee in case of an assignment) is obligated to pay Landlord
under this Lease (after deducting (a) bona fide charges for services provided by
the Tenant to subtenants at rates that are comparable to and not in excess of
rates charged for similar services in the area, and (b) Tenant's actual out-of-
pocket costs of such assignment or subletting, not to exceed $15 per net
rentable square foot multiplied by the number of net rentable square feet
involved, which deduction shall be amortized

                                      31.
<PAGE>

in the case of a subletting in equal monthly installments over the term of the
sublease), prorated to reflect obligations allocable to that portion of the
Premises subject to such assignment or sublease, shall be payable to Landlord as
additional rental under this Lease without affecting or reducing any other
obligations of Tenant hereunder, provided that (A) in no event shall Tenant be
obligated to pay Landlord less than the rental specified in this Lease, and (B)
there are excluded from this clause (iv) any sublease or subleases totalling
less than 30% of the rentable area of the Premises, which exclusion is based on
the condition that at no time during the term of this lease shall there be any
assignment or subletting of 30% or more of the rentable area of the Premises,
(and in the event of the failure of such condition at any time this clause (iv)
shall apply to any consideration thereafter received on account of any
assignment or subletting, including the subletting of less than 30% of the
rentable area of the Premises to which the exclusion otherwise would apply). The
parties hereto acknowledge and agree that it is not their intention that
Tenant's leasehold interest in the Premises have any bonus value or marketable
value to Tenant even though the rentals provided for herein may from time to
time be less than the fair market rental value of the Premises.

               (v)  Tenant shall immediately and irrevocably assign to Landlord,
as security for Tenant's obligations under this Lease, all rental from any
subletting of all or a part of the Premises as permitted by this Lease, and
Landlord, as

                                      32.
<PAGE>

assignee and as attorney-in-fact for Tenant, or a receiver for Tenant appointed
on Landlord's application, may collect such rental and apply it towards Tenant's
obligations under this Lease; except that, until the occurrence of an Event of
Default by Tenant as defined in Section 17, Tenant shall have the right to
collect such rental.

          (d)  Primary Liability. Regardless of Landlord's consent, no
               -----------------
subletting or assignment shall release Tenant of Tenant's obligation or alter
the primary liability of Tenant to pay the rental and to perform all other
obligations to be performed by Tenant hereunder. The acceptance of rental by
Landlord from any other person shall not be deemed to be a waiver by Landlord of
any provision hereof. Consent to one assignment or subletting shall not be
deemed consent to any subsequent assignment or subletting. In the event of
default by any assignees of Tenant or any successor of Tenant in the performance
of any of the terms hereof, Landlord may proceed directly against Tenant without
the necessity of exhausting remedies against such assignee or successor.
Landlord may consent to subsequent assignments or subletting of this Lease or
amendments or modifications to this Lease with assignees of Tenant, without
notifying Tenant, or any successor of Tenant, and without obtaining its or their
consent thereto, and such action shall not relieve Tenant of liability under
this Lease, provided that any such amendments or modifications shall not
increase Tenant's liability hereunder.

                                      33.
<PAGE>

               (e)  Attorneys' Fees. If Tenant shall assign or sublet the
                    ---------------
Premises or request the consent of Landlord to any assignment or subletting, or
if Tenant shall request the consent of Landlord for any act that Tenant proposes
to do, then Tenant shall pay Landlord's reasonable attorneys' fees incurred in
connection therewith.

               (f)  Conflicting Provisions. The provisions of this Section shall
                    ----------------------
prevail and govern over any conflicting provision in any assignment or
subletting to which Landlord gives written consent. Any modification of the
terms of this Lease as between Tenant and Sublessee shall be void and will not
be binding on the Landlord.

               (g)  Brokerage. Tenant shall forever save, indemnify and hold
                    ---------
Landlord harmless from any and all claims for real estate brokerage of persons
claiming by or through Tenant arising from any assignment or subletting.

     15.  Rules. Tenant shall faithfully observe and comply with the rules and
          -----
regulations annexed to this Lease and, after notice thereof, all reasonable
modifications thereof and additions thereto from time to time promulgated in
writing by Landlord. Landlord shall not be responsible to Tenant for the
nonperformance by any other tenant or occupant of the Building of any of said
rules and regulations.

     16.  Entry by Landlord. Landlord may enter the Premises at reasonable hours
          -----------------
to (a) inspect the same, (b) exhibit the same to prospective purchasers,
lenders, or tenants, (c) determine

                                      34.
<PAGE>

whether Tenant is complying with all its obligations hereunder, (d) supply
janitor service and any other service to be provided by Landlord to Tenant
hereunder, (e) post notices of nonresponsibility and (f) make repairs in the
Premises or repairs to any adjoining space or utility services or make repairs,
alterations or improvements to any other portion of the Building (provided,
however, that all such work shall be done as promptly as reasonably possible and
so as to cause as little interference to Tenant as reasonably possible). Without
limiting the foregoing, Landlord may, at any time or from time to time during
the term of this Lease, perform substantial renovation work in and to the
Building or the systems serving the Building (which work may include, but need
not be limited to, the repair or replacement of the Building's exterior facade,
exterior window glass, elevators, electrical systems, air conditioning and
ventilating systems, plumbing system, common hallways, or lobby), any of which
work may require access to the same from within the Premises. Tenant agrees that
(a) Landlord shall have access to the Premises at all reasonable times, upon
reasonable notice, for the purpose of performing such work, and (b) Landlord
shall incur no liability to Tenant, nor shall Tenant be entitled to any
abatement of rent on account of any noise, vibration, or other disturbance to
Tenant's business at the Premises (provided that Tenant is not denied access to
said Premises and Tenant's ability to conduct its business on the Premises is
not substantially impaired thereby) which shall arise out of said access by
Landlord or by

                                      35.
<PAGE>

the performance by Landlord of the aforesaid renovations at the Building.
Landlord shall use reasonable efforts (which shall not include any obligation to
employ labor at overtime rates) to avoid disruption of Tenant's business during
any entry upon the Premises by Landlord permitted by this Section 16.

     Tenant hereby waives any claim for damages for any injury or inconvenience
to or interference with Tenant's business, any loss of occupancy or quiet
enjoyment of the Premises or any other loss occasioned by any such entry or
entries made by Landlord pursuant to any of the foregoing. Landlord shall at all
times have and retain keys with which to unlock all of the doors in, on or about
the Premises (excluding Tenant's vaults, safes and similar areas designated in
writing by Tenant and approved by Landlord in advance); and Landlord shall have
the right to use any and all means which Landlord may deem proper to open such
doors in an emergency in order to obtain entry to the Premises, and any entry to
the Premises obtained by Landlord by any of said means, or otherwise, shall not
under any circumstances be construed or deemed to be a forcible or unlawful
entry into or a detainer of the Premises or an eviction, actual or constructive,
of Tenant from the Premises, or any portion thereof.

     17.  Events of Default. The occurrence of any one or more of the following
          -----------------
events (an "Event of Default") shall constitute a breach of this Lease by
Tenant: (a) if Tenant shall fail to pay rent or any other sum when and as the
same becomes due and payable and such failure shall continue for more than 10
days

                                      36.
<PAGE>

(except that if Landlord has notified Tenant in writing on two occasions during
the 12 months preceding the due date that Tenant has failed to pay rent or any
other sum on the due date, then the failure to pay such rent or other sum on the
due date shall constitute an Event of Default); or (b) if Tenant shall default
in the performance or observance of any other term hereof or of the rules and
regulations described in Section 15 to be performed or observed by Tenant, and
within 30 days following written notice from Landlord to Tenant, Tenant shall
have failed to completely cure such default, or if the nature of such default is
such that it cannot reasonably be cured within such 30 day period, Tenant shall
not within such 30 day period have commenced with prompt diligence the curing of
such default, or, having so commenced, shall thereafter have failed to prosecute
with prompt diligence the complete curing of such default; or (c) if Tenant
shall make a general assignment for the benefit of creditors, or shall admit in
writing its inability to pay its debts as they become due, or shall file a
petition in bankruptcy, or shall be adjudicated a bankrupt or as insolvent, or
shall file a petition in any proceeding seeking any reorganization, arrangement,
composition, readjustment, liquidation, dissolution, or similar relief under any
present or future statute, law, or regulation, or shall file an answer
admitting, or fail to protest timely the material allegations of a petition
filed against it in any such proceeding, or shall seek or consent to or
acquiesce in the appointment of any trustee, receiver, or liquidator of Tenant
or

                                      37.
<PAGE>

any material part of its properties; or (d) if within 45 days after the
commencement of any proceeding against Tenant seeking any reorganization,
arrangement, composition, readjustment, liquidation, dissolution, or similar
relief under any present or future statute, law, or regulation, such proceeding
shall not have been dismissed, or if, within 30 days after the appointment
without the consent or acquiescence of Tenant, of any trustee, receiver, or
liquidator of Tenant or of any material part of its properties, such appointment
shall not have been vacated; or (e) if this Lease or any estate of Tenant
hereunder shall be levied upon under any attachment or execution and such
attachment or execution is not vacated within 30 days; or (f) if Tenant shall
abandon or surrender the Premises, or be dispossessed by process of law or
otherwise, or shall vacate or fail to take possession of the Premises.

     18.  Landlord's Right to Terminate. If an Event of Default shall occur,
          -----------------------------
Landlord at any time thereafter may give a written termination notice to Tenant,
and on the date specified in such notice (which shall be not less than three
days after the giving of such notice) Tenant's right to possession shall
terminate, unless on or before such date all delinquent rent and all other sums
payable by Tenant under this Lease and all costs and expenses incurred by or on
behalf of Landlord hereunder shall have been paid by Tenant and all other
breaches of this Lease by Tenant at the time existing shall have been fully
remedied to the satisfaction of Landlord. Landlord may remove all persons and

                                      38.
<PAGE>

property located therein and hold, administer and dispose of any or all of such
properties in accordance with applicable California law, including California
Civil Code Section 1980 et seq. and California Code of Civil Procedure Section
                        -- ---
1174. Landlord may do all things Landlord deems necessary in order to relet the
Premises, including, without limitation any alterations, repair and/or
restoration of the Premises. Upon such termination, Landlord may recover from
Tenant: (a) the worth at the time of award of the unpaid rental which had been
earned at the time of termination; (b) the worth at the time of award of the
amount by which the unpaid rental which would have been earned after termination
until the time of award exceeds the amount of such rental loss that Tenant
proves could have been reasonably avoided; (c) the worth at the time of award of
the amount by which the unpaid rental for the balance of the term of this Lease
after the time of award exceeds the amount of such rental loss that Tenant
proves could be reasonably avoided; and (d) any other amount necessary to
compensate Landlord for all the detriment proximately caused by Tenant's failure
to perform its obligations under this Lease or which in the ordinary course of
things would be likely to result therefrom. The "worth at the time of award" of
the amounts referred to in clauses (a) and (b) above is computed by allowing
interest at the highest rate legally permitted under applicable law. The "worth
at the time of award" of the amount referred to in clause (c) above is computed
by discounting such amount at the discount rate of the

                                      39.
<PAGE>

Federal Reserve Bank of San Francisco at the time of award plus 1% (one
percent). Notwithstanding any other provisions hereof, any efforts by Landlord
to mitigate damages caused by Tenant's breach of this Lease shall not constitute
a waiver of Landlord's right to recover damages hereunder and shall not affect
the right of Landlord to indemnification pursuant to the provisions of Section
12 hereof.

     19.  Continuation Notwithstanding Default. Even though Tenant has breached
          ------------------------------------
this Lease and abandoned the Premises, this Lease shall continue in effect for
so long as Landlord does not terminate Tenant's right to possession, and
Landlord may enforce all its rights and remedies under this Lease, including the
right to recover the rental as it becomes due under this Lease. Acts of
maintenance or preservation or efforts to relet the Premises or the appointment
of a receiver upon the initiative of Landlord to protect Landlord's interest
under this Lease shall not constitute a termination of Tenant's right to
possession.

     20.  Additional Remedies. The remedies provided for in this Lease are in
          -------------------
addition to any other remedies available to Landlord at law or in equity by
statute or otherwise.

     21.  Landlord's Right to Cure Defaults. All agreements and provisions to be
          ---------------------------------
performed by Tenant under any of the terms of this Lease shall be at its sole
cost and expense and without any abatement of rental. If Tenant shall fail to
pay any sum of money, other than rental, required to be paid by it hereunder, or
shall fail to perform any other act on its part to be performed

                                      40.
<PAGE>

hereunder and such failure shall continue for 10 days after notice thereof by
Landlord, Landlord may, but shall not be obligated to do so, and without waiving
or releasing Tenant from any obligations of Tenant, make any such payment or
perform any such other act on Tenant's part to be made or performed as in this
Lease provided. All sums so paid by Landlord and all necessary incidental costs
shall be deemed additional rent hereunder and shall be payable to Landlord on
demand, and Landlord shall have (in addition to any other right or remedy of
Landlord) the same rights and remedies in the event of the nonpayment thereof by
Tenant as in the case of default by Tenant in the payment of rental.

     22.  Attorneys' Fees. If as a result of any breach or default in the
          ---------------
performance of any of the provisions of this Lease, Landlord uses the services
of an attorney in order to secure compliance with such provisions or recover
damages therefor, or to terminate this Lease or evict Tenant, Tenant shall
reimburse Landlord upon demand for any and all attorneys' fees and expenses so
incurred by Landlord, provided that if Tenant shall be the prevailing party in
any legal action brought by Landlord against Tenant, Tenant shall be entitled to
recover for the fees of its attorneys in such amount as the court may adjudge
reasonable.

     23.  Eminent Domain. If any part of the Premises shall be taken as a result
          --------------
of the exercise of the power of eminent domain, this Lease shall terminate as to
the part of the Premises so

                                      41.
<PAGE>

taken as of the date of taking, and either Landlord or Tenant shall have the
right to terminate this Lease as to the balance of the Premises remaining after
a partial taking by written notice to the other within 30 days after such date,
provided, however, that a condition to the exercise by Tenant of such right to
terminate shall be that such partial taking shall be to such extent and nature
as to substantially and permanently handicap, impede, or impair the conduct of
Tenant's business therein. If all of the Premises are taken as a result of the
exercise of the power of eminent domain, this Lease shall terminate upon the
date of taking. If any part of the Building (other than the Premises) shall be
taken as a result of the exercise of the power of eminent domain, Landlord shall
have the right to terminate this Lease by written notice to Tenant within 30
days from the date of such taking; in the event that Landlord does not so elect,
this Lease shall continue in full force and effect, provided that Tenant is
afforded continuous access to the Premises.

     Landlord shall be entitled to any and all compensation, damages, income,
rent, awards, or any interest therein whatsoever which may be paid or made in
connection with any exercise of the power of eminent domain, and Tenant shall
have no claim against Landlord for the value of any unexpired term of this Lease
or otherwise, except that Tenant shall be entitled to any specific award made in
favor of Tenant covering Tenant's trade fixtures and relocation expenses. In the
event of a partial taking of the Premises which does not result in a termination
of this Lease,

                                      42.
<PAGE>

the monthly rental thereafter to be paid shall abate in proportion to that
portion of the Premises that is rendered unusable by Tenant in the conduct of
its business.

     It is understood and agreed that the foregoing provisions of this Section
are intended to and do fully define and set forth the respective rights and
obligations of the parties in the event of a taking of the Premises or a part
thereof, including without limitation the circumstances under which this Lease
shall or may be terminated, and the disposition of any proceeds of any insurance
or award, and Landlord and Tenant each expressly waives the benefit and effect
of any rights and/or obligations whether purporting to arise by law, by
governmental order, under any insurance contract, or otherwise (including the
provisions of the California Code of Civil Procedure section1265.130), which are
inconsistent with the rights and obligations set forth herein.

     For purposes hereof the "date of taking" shall be deemed to be the date
that physical possession of the property taken is delivered to the condemning
authority.

     24.  Subordination. This Lease shall be subject and subordinate at all
          -------------
times to (a) all ground or underlying leases which may hereafter be executed
affecting the Building and (b) the liens of all mortgages and deeds of trust now
or hereafter placed on or against the Building or on or against Landlord's
interest or estate therein or on or against all such ground or underlying
leases, all without the necessity of having further instruments executed on the
part of Tenant to effect such

                                      43.
<PAGE>

subordination; provided that if and for as long as Tenant is not in default in
the payment of rental or other sums or be otherwise in default under the terms
of this Lease, and Tenant attorns to the Landlord of any such ground or
underlying lease or to the purchaser upon foreclosure of the lien of any
mortgage or deed of trust, or, if requested, enters into a new lease for the
balance of the original or extended term hereof then remaining upon the same
terms and provisions as are in this Lease contained (which attornment or entry
into a new lease Tenant hereby agrees to do), the rights and possession of
Tenant under this Lease shall not be disturbed. Tenant agrees to execute and
deliver upon demand such further instruments evidencing such subordination of
this Lease to such ground or underlying leases, and to the liens of any such
mortgages or deeds of trust, as may be requested by Landlord and/or in such form
as is required by Landlord's lender (including provisions waiving as against
lender claims of, and giving to lender notice of and the right to cure, Landlord
defaults under the Lease).

     25.  No Merger. The voluntary or other surrender of this Lease by Tenant,
          ---------
or a mutual cancellation thereof, shall not work a merger, and, at the option of
Landlord, either shall operate (a) to terminate all or any existing subleases or
subtenancies under the Lease or (b) as an assignment to Landlord of any or all
such subleases and subtenancies.

     26.  Sale. If the original Landlord hereunder, or any successor owner of
          ----
the Building, shall sell or convey the

                                      44.
<PAGE>

Building, all liabilities and obligations on the part of the original Landlord,
or such successor owner, under this Lease accruing thereafter shall terminate,
and thereupon all such liabilities and obligations shall be binding upon the new
owner. Tenant agrees to attorn to such new owner.

     27.  Estoppel Certificate. Tenant shall execute, acknowledge and deliver to
          --------------------
Landlord, within ten (10) days following request by Landlord a certificate
certifying (a) that this Lease is unmodified and in full force and effect (or if
there have been modifications, that this Lease is in full force and effect as
modified and stating the date and nature of each modification), (b) the date, if
any, to which rental and other sums payable hereunder have been paid, (c) that
no notice has been received by Tenant of any default which has not been cured,
except as to defaults specified in said certificate and (d) such other matters
as may be requested by Landlord or Landlord's lender. Any such certificate may
be relied upon by any prospective purchaser, mortgagee, or beneficiary under any
deed of trust on the Building or any part thereof.

     28.  No Light, Air, or View Easement. Any diminution or shutting off of
          -------------------------------
light, air, or view by any structure which may be erected on lands adjacent to
the Building shall in no way affect this Lease or impose any liability on
Landlord.

     29.  Holding Over. If, without objection by Landlord, Tenant holds
          -----------
possession of the Premises after expiration of the term of this Lease, Tenant
shall become a tenant from month to

                                      45.
<PAGE>

month upon the terms, conditions and provisions herein specified but at a
monthly rental equivalent to 150 percent of the then prevailing fair market
rental as determined in good faith by the Landlord but in no event less than the
rental being paid by Tenant in the last month of the term of this Lease, payable
in advance on or before the first day of each month. Each party shall give the
other notice at least one month prior to the date of termination of such monthly
tenancy of its intention to terminate such tenancy.

     30.  Abandonment. Tenant shall not vacate or abandon any part or all of the
          -----------
Premises. If Tenant shall vacate, abandon, or surrender the Premises, or be
dispossessed by process of law or otherwise, any personal property belonging to
Tenant and left on the Premises shall be deemed to be abandoned, at the option
of the Landlord, except such property as may be mortgaged to Landlord.

     31.  Surrender. Tenant shall at the end of the term hereof surrender to
          ---------
Landlord the Premises and all alterations, additions and improvements thereto in
the same condition as when received, ordinary wear and tear and damage by fire,
earthquake, act of God, or the elements excepted. Subject to Landlord's right to
require removal pursuant to Section 7 hereto, all improvements installed in the
Premises by Tenant, shall, without compensation to Tenant, then become
Landlord's property free and clear of all claims to or against them by Tenant or
any third person, and Tenant shall defend and indemnify Landlord against all
liability

                                      46.
<PAGE>

and loss arising from such claims or from Landlord's exercise of the rights
conferred by this Section.

     32.  Waiver. The waiver by either party of any term, agreement, condition,
          ------
or provision herein contained shall not be deemed to be a waiver of any
subsequent breach of the same or any other term, agreement, condition, or
provision herein contained, nor shall any custom or practice which may grow
between the parties in the administration of the terms hereof be construed to
waive or to lessen the right of such party to insist upon the performance by the
other party in strict accordance with said terms. The subsequent acceptance of
rental hereunder by Landlord shall not be deemed to be a waiver of any preceding
breach by Tenant of any term, agreement, condition, or provision of this Lease,
other than the failure of Tenant to pay particular rental so accepted,
regardless of Landlord's knowledge of such preceding breach at the time of
acceptance of such rental.

     33.  Notice. All notices, demands or other writings provided in this Lease
          ------
to be given or made or sent, or which may be given or made or sent by one party
to another party, shall be deemed to have been fully given or made or sent when
made in writing and upon personal delivery (whether by such party or its agent,
or by courier, or by electronic transmissions such as FAX or telex) or after 72
hours following deposit in the United States mail, registered or certified,
postage prepaid, and addressed to such party at the address specified in the
Basic Lease Information, or to such other place as such party may from

                                      47.
<PAGE>

time to time designate in a notice to the other party or parties. Tenant hereby
appoints as its agent to receive the service of all dispossessory or distraint
proceedings and notices thereunder the person in charge of or occupying the
Premises at the time, and, if no person shall be in charge of or occupying the
same, then such service may be made by attaching the same on the main entrance
of the Premises.

     34.  Complete Agreement. There are no oral agreements between Landlord and
          ------------------
Tenant affecting this Lease, and this Lease supersedes and cancels any and all
previous negotiations, arrangements, brochures, agreements, and understandings,
if any, between Landlord and Tenant or displayed by Landlord to Tenant with
respect to the subject matter of this Lease. There are no representations
between Landlord and Tenant other than those contained in this Lease, and all
reliance with respect to any representations is solely upon such
representations.

     35.  Corporate Authority. If Tenant signs as a corporation, each of the
          -------------------
persons executing this Lease on behalf of Tenant does hereby covenant and
warrant that Tenant is a duly authorized and existing corporation, that Tenant
has and is qualified to do business in California, that the corporation has full
right and authority to enter into this Lease, and that the person(s) signing on
behalf of the corporation were authorized to do so.

     36.  Miscellaneous Provisions.
          ------------------------

          (a)  The words "Landlord" and "Tenant" as used herein shall include
the plural as well as the singular.

                                      48.
<PAGE>

          (b)  If there be more than one Tenant, the obligations hereunder
imposed upon Tenant shall be joint and several.

          (c)  Time is of the essence of this Lease and each and all of its
provisions.

          (d)  Submission of this instrument for examination or signature by
Tenant does not constitute a reservation of or option for lease, and it is not
effective as a lease or otherwise until execution and delivery by both Landlord
and Tenant.

          (e)  The agreements, conditions and provisions herein contained shall,
subject to the provisions as to assignment, apply to and bind the heirs,
executors, administrators, successors and assigns of the parties hereto.

          (f)  If any provision of this Lease shall be determined to be illegal
or unenforceable, such determination shall not affect any other provision of
this Lease and all such other provisions shall remain in full force and effect.

          (g)  This Lease shall be governed by and construed pursuant to the
laws of the State of California.

          (h)  All remedies hereinbefore and hereafter conferred upon Landlord
shall be deemed cumulative and no one shall be exclusive of the other, or shall
in any way limit the availability to Landlord of any other remedy conferred by
law, whether or not specifically conferred by the provisions of this Lease.

          (i)  All indemnities of Tenant contained in this Lease shall survive
the expiration or other termination hereof with respect to any act, condition or
event which is the subject

                                      49.
<PAGE>

matter of such indemnity and which occurs prior to such expiration or other
termination.

          (j)  The parties acknowledge and agree that each party has reviewed
and revised, and has been provided the opportunity of its respective counsel to
review and revise, this Lease, and no rule of construction to the effect that
any ambiguities are to be resolved against the drafting party shall be employed
in the interpretation or construction of this Lease, or any amendments or
exhibits thereto, or any other document executed and delivered by either party
in connection therewith.

     37.  Exhibits. The exhibit(s) and addendum, if any, specified in any of the
          --------
Sections of this Lease are attached to this Lease and by this reference made a
part hereof.

     38.  Security Deposit. Tenant shall deposit with Landlord the sum specified
          ----------------
in the Basic Lease Information ("Deposit") prior to January 15, 1993.
Notwithstanding anything in this Lease to the contrary, receipt of the Deposit
shall be a condition precedent to Landlord's obligation to install improvements
to the Premises as provided in Section 2(b) and Exhibit B. The Deposit shall be
held by Landlord as security for the faithful performance by Tenant of all of
the provisions of this Lease to be performed or observed by Tenant. If Tenant
fails to pay rent or other charges due hereunder, or otherwise defaults with
respect to any provision of this Lease, Landlord may use, apply or retain all or
any portion of the Deposit for the payment of any rent or other charge in
default or for the

                                      50.
<PAGE>

payment of any other sum to which Landlord may become obligated by reason of
Tenant's default or to compensate Landlord for any loss or damage which Landlord
may suffer thereby. If Landlord so uses or applies all or any portion of the
Deposit, Tenant, within 10 days after demand therefor, shall deposit cash with
Landlord in an amount sufficient to restore the Deposit to the full amount
thereof, and Tenant's failure to do so shall be a material breach of this Lease.
Landlord shall not be required to keep the Deposit separate from its general
accounts. If Tenant performs all of Tenant's obligations hereunder, the Deposit,
or so much thereof as has not theretofore been applied by Landlord, shall be
returned, without payment of interest or other increment for its use, to Tenant
(or, at Landlord's option, to the last assignee, if any, of Tenant's interest
hereunder) at the expiration of the term hereof, and after Tenant has vacated
the Premises. No trust relationship is created herein between Landlord and
Tenant with respect to the Deposit.

     39.  Brokerage. Each party warrants and represents to the other that such
          ---------
party has not retained the services of any real estate broker, finder or any
other person whose services would form the basis for any claim for any
commission or fee in connection with this Lease or the transactions contemplated
hereby except for (a) real estate brokerage services rendered to Landlord by
Stubbs, Collenette and Associates, the commissions earned with respect to which
Landlord shall pay to such broker pursuant to separate agreement between
Landlord and such broker, and

                                      51.
<PAGE>

<PAGE>

thereof, Landlord shall promptly notify Tenant thereof and of the revisions that
Landlord reasonably requires in order to obtain Landlord's approval. As promptly
as reasonably possible thereafter, Tenant shall submit to Landlord plans and

withheld. This procedure shall be repeated until Tenant's Final Plans are
finally approved by Landlord and written approval has been received by Tenant.
Tenant shall pay Landlord for the review of plans and specifications at the
hourly rate of Landlord's architect, not to exceed a total of $1,500. The final
plans and specifications approved by Landlord, including any changes, additions
or alterations thereto approved by Landlord as provided in Paragraph 2(i) below,
shall be referred to as the "Approved Plans."

     (c)  Tenant shall obtain all building and other permits, licenses and other
approvals necessary to construct the Improvement Work in compliance with all
applicable laws (collectively, "Permits") prior to the commencement of such
work. Tenant's Work shall (i) be constructed in compliance with the Approved
Plans, with all of the terms and conditions of the Lease and with all applicable
laws, (ii) not involve changes to structural components of the Building nor
involve any floor penetrations unless approved by Landlord, in its sole and

contractors and subcontractors shall be acceptable to and approved in writing by
Landlord, which approval shall not be unreasonably withheld, and shall be
subject to administrative supervision by Landlord in

                                      2.
<PAGE>

their use of the Building, provided, however, that any such administrative
supervision shall not impose any liability or obligation whatsoever on Landlord.
Tenant shall furnish to Landlord a copy of the executed contract between Tenant
and Contractor covering all of Tenant's obligations under this Exhibit B.
Tenant's contractors shall conduct their work and employ labor in such manner as
to maintain harmonious labor relations and as not to interfere with any of

with union labor in accordance with the Northern California Master Labor
Agreement and shall comply with all laws, codes and ordinances of the City of
San Francisco, the State Fire Marshall's Office and any authority having
jurisdiction over the project.

     (f)  Tenant shall hire its own general contractor ("Contractor") to
complete Tenant's Work, which Contractor shall be subject to Landlord's prior
written approval, which approval shall not be unreasonably withheld.

     (g)  Contractor shall obtain a "course of construction" policy of insurance

prior written notice to Landlord.

     (h)  Tenant shall cause Contractor to use ACCO and CBF, Inc., for its HVAC
and electrical work, respectively.

     (i)  If Tenant shall request any change, addition or alteration in Tenant's
Work from the Approved Plans approved by Landlord, Tenant's Architect (as
hereinafter defined) shall prepare plans and specifications with respect to such
change, addition or alteration, which plans and specifications shall be
submitted to Landlord and shall be subject to Landlord's prior written approval,
which approval may be withheld in Landlord's sole discretion. Only new and
first-class materials shall be used in the construction of the Improvement Work,
except with the written consent of Landlord.

     (j)  Trash removal will be done continually at Tenant's cost and expense.
No trash, or other debris, or other waste may be deposited at any time outside
the Premises. If so, Landlord

                                      3.

may remove it at Tenant's expense, which expense shall equal the cost of removal

     (k)  Storage of Tenant's contractors' construction materials, tools and
equipment shall be confined within the Premises.

     (l)  Landlord shall have the right to post in a conspicuous location on
Tenant's Premises, as well as record with the City and County of San Francisco,

complete sets of plans (one in electronic format compatible with AutoCAD Release
14 or earlier) and specifications covering all of the Improvement Work,
including architectural, electrical, and plumbing, as built.

     3.   Tenant Improvement Allowance.
          ----------------------------

     (a)  Landlord shall provide Tenant with a cash tenant improvement allowance
(the "Tenant Improvement Allowance") of up to $431,860. The Tenant Improvement
Allowance shall be applied to hard costs of construction and for Tenant's
architectural and engineering expenses in connection with the Improvement Work.
Tenant shall bear and pay the cost of the Improvement Work in excess of the
Tenant Improvement Allowance payable to Tenant. Based upon applications for
payment prepared, certified and submitted by Tenant, Landlord shall make a
progress payments from the Tenant Improvement Allowance in accordance with the
provisions of this Paragraph 3.

     (b)  As a condition to the first disbursement of the Tenant Improvement
Allowance, all of the following conditions must be satisfied:

          (i)  Tenant shall have delivered to Landlord duly executed originals
of each of (A) the agreement between Tenant and the licensed architect
("Tenant's Architect") engaged by Tenant and approved by Landlord, in its
reasonable discretion, for the design and oversight of the Improvement Work (the
"Architect Agreement") and (B) the guaranteed maximum cost contract with
Contractor for the construction of the Improvement Work (the "Tenant Improvement
Contract").

          (ii) Landlord shall have approved the budget for the Improvement Work.

                                      4.
<PAGE>

The Approved Plans shall have been completed and approved.

          (iii) Tenant shall have obtained and be in compliance with all
Permits.

     (c)  Not later than the 25th day of each month Tenant shall submit
applications for payment to Landlord in a form satisfactory to Landlord,
certified as correct by an officer of Tenant and by Tenant's Architect, for
payment of that portion of the cost of the Improvement Work allocable to
expenses reimburseable from the Tenant Improvement Allowance incurred during the
period from the first day of the same month projected through the last day of
the month. Each application for payment shall set forth such information and
shall be accompanied by such supporting documentation as shall be requested by
Landlord, including the following:

          (i)   Fully executed conditional lien releases in the form prescribed
by law from the Contractor and all subcontractors and suppliers furnishing labor
or materials during such period and fully executed unconditional lien releases
from all such entities covering the prior payment period.

          (ii)  Contractor's worksheets showing percentages of completion,
detailing the portion of the work completed and the portion not completed, and
the ten percent (10%) retainage to be held by Tenant pursuant to the Tenant
Improvement Contract until substantial completion of the Improvement Work.

          (iii) Contractor's certification as follows:

                "There are no known mechanics' or materialmen's liens
outstanding at the date of this application for payment, all due and payable
bills with respect to the Building have been paid to date or shall be paid from
the proceeds of this application for payment, and there is no known basis for
the filing of any mechanics' or materialmen's liens against the Building, and,
to the best of our knowledge, waivers from all subcontractors are valid and
constitute an effective waiver of lien under applicable law to the extent of
payments that have been made or shall be made concurrently herewith."

          (iv)  All documents necessary to effect and perfect the transfer of
title to the materials or equipment for which application for payment is made.

          (v)   Invoices for labor rendered and materials delivered to the
Premises.

     (d)  On or before the 25th day of the month following submission of the
application for payment, Landlord shall make payment to Tenant of an amount
equal to the Tenant Improvement

                                      5.
<PAGE>

defined), provided that, (A) no default exists under the Lease, (B) no default
exists under either of the Tenant Improvement Contract or the Architect
Agreement, (C) no lien has been filed with respect to the Improvement Work that
has not been released, (D) Tenant is in compliance with all Permits, (E) all
insurance required hereunder and under the Lease is in full force and effect and

any work with the Approved Plans or due to any substandard work, or for any
other reason. Landlord has no obligation to make any payments to Contractor's
material suppliers or subcontractors or to determine whether amounts due them
from Contractor in connection with the Improvement Work have, in fact, been
paid. As used herein, the "Tenant Improvement Portion" shall be equal to the
amount requested by Tenant in the application for payment multiplied by a
fraction, the numerator of which is the amount of the Tenant Improvement
Allowance and the denominator of which is the total cost of the Improvement Work
as set forth in the Tenant Improvement Contract. Tenant agrees that Landlord
shall have the right, at all times prior to Tenant's satisfaction of all
conditions precedent to Landlord's final disbursement of the Tenant Improvement
Allowance, to withhold from each payment to Tenant of the Tenant Improvement
Portion an amount equal to ten percent (10%) of each such Tenant Improvement
Portion (the "Retained Amount"), which Retained Amount shall not be paid to
Tenant until all of the conditions set forth in Paragraph 3(e) below are
completed to Landlord's satisfaction.

     (e)  In addition to the requirements set forth above, as a condition to the
final disbursement of the Tenant Improvement Allowance, all of the following
conditions must be satisfied:

          (i)   The Improvement Work shall have been completed to the reasonable
satisfaction of Landlord.

          (ii)  Tenant shall have obtained and be in compliance with all
Permits, and have provided Landlord with a copy of each Permit fully and finally

          (iii) Tenant shall submit an application for payment to Landlord,
certified as correct by Tenant, setting forth such information and accompanied
by such supporting documentation as shall be reasonably requested by Landlord.

                                      6.
<PAGE>

          (iv)  Tenant shall have provided, to Landlord's satisfaction, all
items required in Paragraph 4 below.

     (f)  On or before the 30th day following submission of the application for
payment in full satisfaction of all conditions set forth in clause (e)
immediately above, Landlord shall make payment to Tenant of the final amount due
Tenant, including the Retained Amount.

     (g)  Notwithstanding anything contained herein, in no event shall Landlord
be obligated to make payments in excess of the Tenant Improvement Allowance.

     (h)  Landlord's payment of any amounts of the Tenant Improvement Allowance
shall in no event be deemed to be Landlord's approval or acceptance of the work
furnished or materials supplied as set forth in Tenant's payment request.

     4.   Evidence of Completion of Improvement Work. Upon the completion of the
          ------------------------------------------
Improvement Work, Tenant shall:

     (a)  Submit to Landlord a detailed breakdown of Tenant's final and total
construction costs, together with receipted evidence showing payment thereof,

Schedule "A" - Site Plan
<PAGE>

     THIS AGREEMENT, made the day of 199 , by and between FIRST INDUSTRIAL,
L.P., a Delaware limited partnership, having an office at 354 Eisenhower
Parkway, Livingston, New Jersey 07039 (having a mailing address at P.O. Box
1639, Livingston, New Jersey 07039), hereinafter called the "Landlord"; and
2BRIDGE SOFTWARE, INC., a California corporation, about to have an office at 11
Princess Road, Lawrenceville, New Jersey 08532, hereinafter called the "Tenant".

                                  WITNESSETH:
                                  -----------

     WHEREAS, the Landlord intends to lease to the Tenant Suite C, in the
building commonly known as 11 Princess Road, Lawrenceville, New Jersey,
hereinafter referred to as the "Building", which Suite contains approximately
5,000 square feet, outside outside dimensions to center line of common wall,
identified on the plot plan attached hereto and made a part hereof as Schedule
"A", hereinafter referred to as the "Leased Premises"; and

     WHEREAS, the parties hereto wish to mutually define their rights, duties
and obligations in connection with the said lease,

     NOW, THEREFORE, KNOW ALL MEN BY THESE PRESENTS, that for the rents
reserved, the mutual considerations herein and the parties mutually intending to
be legally bound hereby, the Landlord does demise, lease and let unto the Tenant
and the Tenant does rent and take from the Landlord the Leased Premises as
described in Article 1, and the Landlord and Tenant do hereby mutually covenant
and agree as follows:

     1.   LEASED PREMISES
          ---------------

          1.1  The Leased Premises shall consist of Suite C located in the
Building, which Suite contains approximately 5,000 square feet outside
dimensions to center line of common wall, identified on the plot plan attached
hereto and made a part hereof as Schedule "A", together with all easements,
improvements, tenements, appurtenances, hereditament, fixtures and rights and
privileges appurtenant thereto, and any and all fixtures and equipment which
have been installed in said Building by the
<PAGE>

Landlord for the use of the Tenant in its occupancy of the Leased Premises.

          1.2  The Building is a part of the complex (the "Complex") upon which
Landlord has constructed three (3) additional buildings in addition to the
Building. The Complex comprises one designated lot and block (hereinafter
referred to as the "Property") as reflected on the Official Tax Map of the
Township of Lawrenceville. To the extent that Tenant shall be responsible under
this lease for Tenant's percentage of costs attributable to the Building only,
the same shall hereinafter be referred to as the "Building Percentage". To the
extent that Tenant's percentage of costs shall be applicable to the Property
(including the common areas thereof), exclusive of the Building and the other
buildings which have been constructed by Landlord, such Tenant's percentage
shall hereinafter be referred to as the "Common Area Percentage". For the
purposes of this lease the total gross rentable area of the Building is 55,000
square feet, and the total gross rentable area of all of the buildings on the
Complex is 118,750 square feet. The Building Percentage has been established at
9.1% and the current Common Area Percentage has been established at 4.2%. In the
event of any change in the size of the Leased Premises, Building or the Complex,
the Landlord shall certify to Tenant the resulting gross rentable area of the
Building, the Leased Premises and the Complex. If the certification indicates
applicable gross rentable area of the Leased Premises, Building and/or Complex
at variance with the square footage used to initially establish the Common Area
Percentage and the Building Percentage, Landlord and Tenant shall enter into a
lease amendment to reflect any required revisions and adjustment of such
applicable percentages, or any other applicable lease terms.

     2.   TERM OF LEASE
          -------------

          The Landlord leases unto the Tenant and the Tenant hires the Leased
Premises for the term of three (3) years, to commence on or about December 1,
1999, and to end on November 30, 2002, the

                                       2
<PAGE>

obligation of the Tenant hereunder being subject to the following proviso:

          2.1  That on or about December 1, 1999, the Landlord shall have
delivered to the Tenant a Certificate of Occupancy issued by the authorized
issuing officer of the governmental instrumentality having jurisdiction thereof.
Upon the delivery by the Landlord to the Tenant of the Leased Premises, and the
Certificate of Occupancy hereinabove mentioned, the lease term shall commence
and the Tenant's obligation to pay rent shall begin (subject to the provisions
of Article 2.2 hereof).

          2.2  Subject to the terms and conditions of this lease, in the event
the Leased Premises are delivered to the Tenant in the manner provided in
Article 2.1 above, prior to or after December 1, 1999, the lease term of three
(3) years shall commence on the first day of the next succeeding month following
delivery of possession to the Tenant (hereinafter called the "Commencement
Date") and shall continue for a term of three (3) years thereafter. The Tenant
shall, however, pay to the Landlord a sum equal to the pro rata share of one (1)
month's rent for that portion of the month prior to the Commencement Date.
During said period of partial monthly occupancy, if any, all other terms and
conditions of this lease shall be applicable to the occupancy of the Leased
Premises by the Tenant.

          2.3  In the event the Landlord has not delivered the Leased Premises
to Tenant within sixty (60) days of the later of (a) full execution of this
lease and (b) delivery by Tenant to Landlord of any executed application and/or
any other documentation required in order to obtain a certificate of occupancy.
Tenant acknowledges that the ability of the Landlord to deliver the Leased
Premises to the Tenant shall not be delayed due to the unavailability of the
carpet or paint selected by the Tenant. In such event, Tenant shall timely make
alternate choices of building standard carpet and paint in lieu of the
selections originally made.

                                       3
<PAGE>

     3.   RENT
          ----

          3.1  The Tenant covenants and agrees to pay, in good and useable
funds, the annual rent ("Base Rent") as follows:

          (a)  During the first (1st) and second (2nd) years of the lease term,
Tenant shall pay Base Rent in the amount of SIXTY THOUSAND AND 00/100
($60,000.00) DOLLARS per annum, in equal installments in the sum of FIVE
THOUSAND AND 00/100 ($5,000.00) DOLLARS per month.

          (b)  During the third (3rd) year of the lease term, Tenant shall pay
Base Rent in the amount of SIXTY ONE THOUSAND TWO HUNDRED FIFTY AND 00/100
($61,250.00) DOLLARS per annum, in equal monthly installments in the sum of FIVE
THOUSAND ONE HUNDRED FOUR AND 17/100 ($5,104.17) DOLLARS.

          All of the foregoing monthly payments shall be made promptly in
advance on the first day of each and every month during the term of the lease
without demand and without off-set or deduction, together with such additional
rent and other charges ("Additional Rent") required to be paid by Tenant as are
herein-after set forth.

          3.2  Simultaneously with the execution hereof, the Tenant has
delivered to the Landlord the first monthly installment of Base Rent payable
hereunder, together with the security deposit referred to herein.

          3.3  Any installment of Base Rent or Additional Rent accruing
hereunder (collectively "rent"), and any other sum payable hereunder by Tenant
to Landlord which is not paid prior to the fifth (5th) day of any lease month,
shall bear a late charge of eight (8%) per cent of such Base Rent or Additional
Rent, to be paid therewith, and the failure to pay such charge shall be a
default. Such late charge shall be deemed to be Additional Rent hereunder. It is
expressly understood and agreed that the foregoing late charge is not a penalty,
but agreed upon compensation to the Landlord for administrative costs incurred
by Landlord in connection with any such late payment. In addition,

                                       4
<PAGE>

any payment of Base Rent or Additional Rent, which is not paid within thirty
(30) days of the date upon which it is due shall require the payment of interest
at the rate of fifteen (15%) percent per annum, calculated from the date that
such payment was due through the date that any such payment is actually made.

     4.   PARKING AND USE OF EXTERIOR AREA
          --------------------------------

          4.1  The Tenant shall have the right, at no additional cost, to use
the parking spaces on a non-exclusive basis in common with other tenants of the
Complex and to use the access driveways and allocated parking spaces for its
business purposes and for those of its agents, servants, employees or invitees.
The Landlord reserves the right to allocate designated parking spaces if
Landlord chooses. The Landlord and Tenant mutually agree that they will not
block, hinder or otherwise obstruct the access driveways and parking areas so as
to impede the free flow of vehicular traffic in and out of the Complex. In
connection with the use of the loading platforms, if any, both Landlord and
Tenant agree that they will not use the same in connection with the conduct of
their business so as to unreasonably interfere with the use of the access
driveways and parking areas.

          4.2  The Tenant may not utilize any portion of the land outside of the
Leased Premises for outside storage of raw materials or finished products.

     5.   USE
          ---

          The Tenant covenants and agrees to use and occupy the Leased Premises
for office and warehouse purposes only, which use by Tenant, however, is and
shall be expressly subject to all applicable zoning ordinances, rules and
regulations of any governmental instrumentalities, boards or bureaus having
jurisdiction thereof.

     6.   CONDITION OF LEASED PREMISES
          ----------------------------

          6.1  Anything herein contained to the contrary notwithstanding, it is
expressly understood and agreed that the Tenant shall take the Leased Premises
and improvements as of the

                                       5
<PAGE>

Commencement Date of the within lease in an "as is" condition, except that
Landlord shall, prior to the delivery of the Leased Premises, recarpet the
existing office area, and also repaint the same, using building standard
materials

          6.2  In the event that any changes or additions are required to the
Leased Premises by any governmental or quasi governmental entity having
jurisdiction over the Tenant, or its use and occupancy of the Leased Premises,
including any required modification to the fire suppression system serving the
same, any such changes or additions shall be performed by the Landlord at the
Landlord's sole cost and expense unless the same is required due to Tenant's
particular use of the Leased Premises. In addition, in the event that the
performance of any such changes or additions required due to Tenant's particular
use of the Leased Premises shall delay the Commencement Date hereunder, the
Commencement Date shall be established as of the date that the Leased Premises
would otherwise have been delivered by the Landlord to Tenant, but for such
additional requirements which are applicable to the Tenant.

     7.   REPAIRS AND MAINTENANCE
          -----------------------

          7.1  The Tenant shall take good care of the Leased Premises and, at
its cost and expense, keep and maintain in good repair the interior of the
Leased Premises, including all repairs to the floor, the air-conditioning and
heating plant, the plumbing, pipes, sewer lines and conduits, and fixtures
belonging thereto; and shall replace all air-conditioning, electrical, heating
and plumbing plants, fixtures and systems, including mechanical and working
parts as may be required; and shall replace all ballasts and fluorescent
fixtures; and shall maintain interior water and sewer pipes and connections, and

shall, at the end or the expiration of the term, deliver up the Leased Premises
in good order and condition, damages by fire or casualty, the elements and
ordinary wear and tear excepted. The Tenant expressly agrees that it shall enter
into a periodic maintenance agreement with a

                                       6
<PAGE>

reputable heating, ventilating and air-conditioning contractor, which contract
shall provide for a minimum of two (2) inspections per year. A copy of said
contract shall be forwarded to the Landlord prior to the Commencement Date and
thereafter on an annual basis, and copies of inspection reports shall be
delivered to the Landlord within ten (10) days of receipt thereof by Tenant. The
Tenant covenants and agrees that it shall not cause or permit any waste (other
than reasonable wear and tear), damage or disfigurement to the Leased Premises,
or any overloading of the floors of the Building, constituting part of the
Leased Premises. Tenant shall reimburse Landlord in connection with exterior
maintenance and repairs as hereinafter provided in Article 7.2.

          7.2  The Tenant shall pay to the Landlord monthly, as Additional Rent,
a sum equal to Tenant's Common Area Percentage of costs incurred by the Landlord
for the management, maintenance, repair and replacement of the following: (i)
parking lot and roadways, driveways, sidewalks, walkways, exterior lighting;
(ii) exterior sewer and utility lines; (iii) lawns and shrubbery; (iv) snow
removal; (v) signs serving the Complex; and (vi) detention ponds. In addition
the Tenant shall pay the Landlord monthly, as Additional Rent, Tenant's Building
Percentage of costs incurred by the Landlord for the maintenance, repair and
replacement of the following: roof, gutters, leaders, flashings, metal gravel
stops and roof drains. Landlord shall be responsible at its sole cost for the
maintenance, repair and replacement of the exterior walls, load bearing interior
walls and the foundation of the Leased Premises unless arising from the
negligence or willful misconduct of Tenant, its agents, employees or
contractors. Landlord shall be solely responsible for the cost of repairing
original construction defects and the costs of repairs and replacements incurred
by reason of fire or other casualty. Notwithstanding the above, the cost of any
replacement of the roof of the Building, exterior sewer and utility lines,
repaving of the parking lot or replacement of the heating, ventilating and air
conditioning system shall be each

                                       7
<PAGE>

amortized on a straight line basis over its useful life which is deemed to be
ten (10) years in each instance and Tenant shall be responsible to reimburse the
Landlord for that portion of such amortized costs as is applicable to the then
remaining term of this lease based on Tenant's Common Area Percentage. In the
event of any subsequent renewal or extension of this lease, Tenant shall be
responsible to reimburse the Landlord for that portion of such amortized costs
which is applicable to the renewal or extension term based on Tenant's Common
Area Percentage.

          7.3  During the first year of the lease term, the Landlord shall
estimate the cost of all of the management, maintenance, repair and replacement
services required pursuant to Article 7.2 above, inclusive of management fees.
Landlord shall furnish such estimate to the Tenant, and Tenant shall pay to
Landlord one-twelfth (1/12th) of its Common Area Percentage or Building
Percentage thereof, as applicable, during each month of the lease year as
Additional Rent. At the expiration of the first twelve (12) months of the lease
term, the Landlord shall furnish to Tenant a breakdown, certified by the
Landlord, as to the total cost of management, maintenance, repair and
replacement for the prior twelve (12) months. Upon Landlord's receipt of a
written request from Tenant within sixty (60) days after Tenant's receipt of the
annual certified statement, the Landlord shall forward copies of all relevant
invoices, contracts and other documentation in support of the Landlord's
certified statement for Tenant's review. In the event Tenant's pro rata share
shall be more than the aggregate paid by the Tenant during the preceding twelve
(12) month period, Tenant shall pay to the Landlord, in one lump sum, any
difference in such obligation, said sum to be paid within fifteen (15) days
after demand. In the event Tenant shall have overpaid its pro rata share, any
such overage shall be applied to the monthly management, maintenance, repair and
replacement charges prospectively due under the lease. This procedure shall be
followed during each year of the lease term, and at the expiration of the lease,
any overage or

                                       8
<PAGE>

underage shall be credited or paid after computation by the Landlord, which
obligation of Landlord and Tenant shall survive the expiration of the lease
term.

          7.4  The Tenant expressly covenants and agrees to replace any broken
glass in the windows or other apertures of the Leased Premises which become
damaged or destroyed, at Tenant's sole cost and expense.

     8.   UTILITIES
          ---------

          8.1  The Tenant shall, at its own cost and expense, pay all utility
meter and service charges applicable to the Leased Premises, including gas,
sewer, electric, water, janitorial and garbage disposal services and Tenant's
Building Percentage of standby sprinkler charges, if any. It is understood and
agreed that if the Leased Premises are not separately metered for any utility
service, the Tenant shall pay its pro rata share of the charges indicated by the
applicable utility meter serving the Leased Premises, based upon the
relationship between the gross rentable area of the Leased Premises and the
gross rentable area of all of the premises served by said utility meter.

          8.2  The Landlord is hereby granted the privilege of entering the
Leased Premises for the purpose of repairing any utility lines which serve the
Leased Premises. Any entry shall be upon reasonable prior oral notice except in
the event of emergency.

     9.   TAXES
          -----

          9.1  The Tenant, in addition to the rent reserved, shall, during the
term of the lease, promptly pay to the Landlord, monthly, in advance, its
proportionate part of all real estate and personal property taxes assessed
against the Complex for land, buildings and improvements. Said obligation shall
be prorated as of the commencement and expiration of the lease term. In addition
to the obligation to pay real estate taxes as hereinabove set forth, the Tenant
shall, during the term of this lease, pay to the Landlord monthly, in advance,
its proportionate part of any levy for the installation of local improvements
affecting the Complex as

                                       9
<PAGE>

may be assessed by any governmental body having jurisdiction thereof. The real
estate tax obligation of the Tenant shall include any tax or imposition for
parking lot usage which may be levied by any governmental body having
jurisdiction thereof. For the purpose of this Lease Tenant's obligation to pay
taxes assessed against the land shall be based on the Common Area Percentage
applied to the assessed valuation of the land, and resultant taxes produced, and
if the Building is assessed separately Tenant's obligation for such portion of
the real estate taxes shall be based on the Building Percentage of such tax. If
however, all of the buildings in the Complex are not separately assessed the
Tenant's obligations shall be equal to the Common Area Percentage of the real
estate tax attributable thereto.

          9.2  The Landlord may contest any assessment or levy of taxes on the
Complex. A contest conducted by the Landlord may include the Complex and other
land and buildings owned by the Landlord. The Tenant shall have no right to
prosecute a tax appeal affecting the Complex.

          9.3  If at any time during the term of this lease the method or scope
of taxation prevailing at the commencement of the lease term shall be altered,
modified or enlarged so as to cause the method of taxation to be changed, in
whole or in part, so that in substitution for the real estate taxes now assessed
there may be, in whole or in part, a capital levy or other imposition based on
the value of the Complex, or the rents received therefrom, or some other form of
assessment based in whole or in part on some other valuation of the Complex,
then and in such event, such substituted tax or imposition shall be payable and
discharged by the Tenant in the manner required pursuant to such law promulgated
which shall authorize such change in the scope of taxation, and as required by
the terms and conditions of the within lease.

          9.4  Nothing in this lease contained shall require the Tenant to pay
any franchise, estate, inheritance, succession, capital levy or transfer tax of
the Landlord, or Federal Income

                                       10
<PAGE>

Tax, State Income Tax, or excess profits or revenue tax, unless such taxes are
in substitution for real property taxes.

          9.5  The Tenant shall pay to Landlord monthly, as Additional Rent,
one-twelfth (1/12th) of Tenant's proportionate share of annual real estate taxes
and assessments to be paid by Tenant, as provided in Article 9.1 above. Landlord
shall adjust Tenant's rent payment from time to time based on annual tax
requirements, and Landlord shall furnish to Tenant, if requested, a computation
and breakdown of Tenant's tax obligation.

     10.  INSURANCE
          ---------

          10.1 The Tenant agrees to pay monthly, in advance, as Additional Rent,
Tenant's Building Percentage of the annual insurance premium or premiums charged
to the Landlord for insurance coverage which insures the Building. The insurance

Landlord or Tenant as the same may be applicable, which right to the extent not

force and effect during the period of Landlord's restoration, except that Base
Rent and Additional Rent shall abate, upon the happening of fire or

                                       15

or other damage to the Leased Premises.

          14.4 Notwithstanding anything contained in Article 14.1 or 14.2 above,
if such repairs are for any reason not completed within two hundred ten (210)
days, then the Tenant shall have the right to terminate this lease upon written
notice to the Landlord of such election, and in such event of termination

occupancy of the Leased Premises, it will, during the lease term, promptly, at
Tenant's cost and expense, execute and comply with all statutes, ordinances,
rules, orders, regulations and requirements of the Federal, State and Municipal
governments and of any and all their instrumentalities, departments and

                                       16
<PAGE>

bureaus, applicable to the Leased Premises, as the same may require correction,
prevention and abatement of nuisances, violations or other grievances, in, upon
or connected with the Leased Premises, and/or arising from the operations of the
Tenant therein.

               (ii)  The Tenant covenants and agrees, at its own cost and
expense, to comply with such regulations or requests as may be required by the
fire or liability insurance carriers providing insurance for the Leased
Premises, and will further comply with such other requirements that may be
promulgated by the Board of Fire Underwriters, in connection with the use and
occupancy by the Tenant of the Leased Premises in the conduct of its business.

               (iii) The Tenant covenants and agrees that it will not commit any
nuisance, nor permit the emission of any objectionable sound, noise or odors
which would be violative of any applicable governmental rule or regulation or
would per se create a nuisance. The Tenant further covenants and agrees that it
will handle and dispose of all rubbish, garbage and waste in connection with the
Tenant's operations in the Leased Premises in accordance with reasonable
regulations established by the Landlord from time to time in order to keep the
premises in an orderly condition and in order to avoid unreasonable emission of
dirt, fumes, odors or debris which may constitute a nuisance or induce pests or
vermin.

               (iv)  Notwithstanding anything to the contrary contained in this
Article 15.1, Tenant shall have no obligation to alter or improve the Leased
Premises or any portion thereof to comply with any legal or insurance
requirement unless such requirement is triggered by the particular specific
manner in which Tenant uses the Leased Premises.

          15.2 In case the Tenant shall fail or neglect to comply with the
aforesaid statutes, ordinances, rules, orders, regulations and requirements or
any of them, or in case the Tenant shall neglect or fail to make any necessary
repairs, then the Landlord or the Landlord's agents may after ten (10) days'
notice (except for

                                       17
<PAGE>

emergency repairs, which may be made immediately) enter the Leased Premises and
make said repairs and comply with any and all of the said statutes, ordinances,
rules, orders, regulations or requirements, at the cost and expense of the
Tenant and in case of the Tenant's failure to pay therefor, the said cost and
expense shall be added to the next month's rent and be due and payable as such,
or the Landlord may deduct the same from the balance of any sum remaining in the
Landlord's hands. This provision is in addition to the right of the Landlord to
terminate this lease by reason of any default (beyond any applicable notice and
cure periods) on the part of the Tenant, subject to the rights of the Tenant as
herein-above mentioned in the manner as in this lease otherwise provided.

          15.3 Without limiting anything hereinabove contained in this Article
15, Tenant expressly covenants and agrees to fully comply with the provisions of
the New Jersey Industrial Site Recovery Act (N.J.S.A. 13:1K-6, et seq.)
hereinafter referred to as "ISRA", and all regulations promulgated thereto (or
under its predecessor statute, the New Jersey Environmental Cleanup
Responsibility Act) prior to the expiration or earlier termination of the within
lease or at any time that any action of the Tenant triggers the applicability of
ISRA. In particular, the Tenant agrees that it shall comply with the provisions
of ISRA in the event of any "closing, terminating or transferring" of Tenant's
operations, as defined by and in accordance with the regulations which have been
promulgated pursuant to ISRA. In the event evidence of such compliance is not
delivered to the Landlord prior to surrender of the Leased Premises by the
Tenant to the Landlord, it is understood and agreed that the Tenant shall be
liable to pay to the Landlord an amount equal to two times the annual Base Rent
then in effect, prorated on a monthly basis, together with all applicable
additional rent from the date of such surrender until such time as evidence of
compliance with ISRA has been delivered to the Landlord, and together with any
costs and expenses incurred by Landlord in enforcing Tenant's obligations under
this Article 15.3.

                                       18
<PAGE>

Evidence of compliance, as used herein, shall mean a "letter of non-
applicability" issued by the New Jersey Department of Environmental Protection,
hereinafter referred to as "NJDEP", or an approved "no further action letter" or
a "remediation action workplan" which has been fully implemented and approved by
NJDEP. Evidence of compliance shall be delivered to the Landlord, together with
copies of all submissions made to, and received from, the NJDEP, including all
environmental reports, test results and other supporting documentation. In
addition to the above, Tenant hereby agrees that it shall cooperate with
Landlord in the event of the termination or expiration of any other lease
affecting the Property, or a transfer of any portion of the property indicated
on Schedule "A", or any interest therein, which triggers the provisions of ISRA.
In such case, Tenant agrees that it shall fully cooperate with Landlord in
connection with any information or documentation which may be requested by the
NJDEP. In the event that any remediation of the Property is required in
connection with the conduct by Tenant of its business in the Leased Premises,
Tenant expressly covenants and agrees that it shall be responsible for that
portion of said remediation which is attributable to the Tenant's use and
occupancy thereof. Tenant hereby represents and warrants that its Standard
Industrial Classification No. is          , and that Tenant shall not generate,
manufacture, refine, transport, treat, store, handle or dispose of "hazardous
substances" as the same are defined under ISRA and the regulations promulgated
pursuant thereto. Tenant hereby agrees that it shall promptly inform Landlord of
any change in its SIC number or the nature of the business to be conducted in
the Leased Premises. Landlord hereby represents to the best of its knowledge
without making any independent inquiry that Landlord is not aware of any
environmental condition affecting the Property including the Leased Premises.
The Landlord hereby agrees that it shall indemnify, defend and save harmless the
Tenant from and against all claims or liabilities incurred in connection with
the environmental condition

                                       19
<PAGE>

of the Leased Premises existing prior to the Commencement Date hereunder. In no
event shall Tenant be liable for hazardous substances migrating onto or under
the Leased Premises except if such migration is caused by Tenant, its agents,
employees or contractors. The within covenants shall survive the expiration or
earlier termination of the lease term.

     16.  INSPECTION BY LANDLORD
          ----------------------

          The Tenant agrees that the Landlord's agents, and other
representatives, shall have the right, during normal business hours, to enter
into and upon the Leased Premises, or any part thereof, with reasonable prior
oral notice at all reasonable hours for the purpose of examining the same, or
for exhibiting the same to prospective tenants [within the last eight (8) months
of the term of this lease or at any time during which the Tenant is in default
under the terms and conditions of this lease] and purchasers (at all times) in
the presence of a representative of Tenant (except in the event of emergency) or
making such repairs or alterations therein as may be necessary for the safety
and preservation thereof, without unduly or unreasonably disturbing the
operations of the Tenant (except in the event of emergency).

     17.  DEFAULT BY TENANT
          -----------------

          17.1 Each of the following shall be deemed a default by Tenant and a
breach of this lease:

               (1)  (i)   filing of a petition by the Tenant for adjudication as
     a bankrupt, or for reorganization, or for an arrangement under any federal
     or state statute, except in a Chapter 11 Bankruptcy where the Base Rent and
     Additional Rent stipulated herein is being paid and the terms of the lease
     are being complied with;

                    (ii)  dissolution or liquidation of the Tenant;

                    (iii) appointment of a permanent receiver or a permanent
     trustee of all or substantially all of the property of the Tenant, if such
     appointment shall not be vacated within sixty (60) days, provided the Base
     Rent and Additional Rent stipulated herein is being paid and the terms of
     the lease are being complied with, during said one hundred twenty (120) day
     period;

                    (iv)  taking possession of the property of the Tenant by a
     governmental officer or agency pursuant to statutory authority for
     dissolution, rehabilitation, reorganization or liquidation of the Tenant if
     such taking of possession shall not be vacated within sixty (60) days,
     provided the Base Rent and Additional Rent stipulated herein is being paid
     and the terms of the lease are being complied with, during said one hundred
     twenty (120) day period;

                                       20
<PAGE>

                    (v) making by the Tenant of an assignment for the benefit of
creditors;

                    (vi) abandonment of the Leased Premises by the Tenant.

          If any event mentioned in this subdivision (1) shall occur, Landlord
may thereupon or at any time thereafter elect to cancel this lease by ten (10)
days' notice to the Tenant and this lease shall terminate on the day in such
notice specified with the same force and effect as if that date were the date
herein fixed for the expiration of the term of the lease.

               (2)  (i)  Default in the payment of the Base Rent or Additional
     Rent herein reserved or any part thereof for a period of seven (7) days
     after the same is due and payable as in this lease required.

     condition of this lease on the part of the Tenant to be performed for a
     period of thirty (30) days after notice. For purposes of this subdivision
     (2) (ii) hereof, no default on the part of Tenant in performance of work
     required to be performed or acts to be done or conditions to be modified
     shall be deemed to exist if steps shall have been commenced by Tenant
     diligently after notice to rectify the same and shall be prosecuted to
     completion with reasonable diligence, and if the Landlord is indemnified
     against loss or liability arising from the default.

          17.2  In case of any such default under Article 17.1 (2), at any time
following the expiration of the respective grace periods above mentioned,
Landlord may serve a notice upon the Tenant electing to terminate this lease
upon a specified date not less than seven (7) days after the date of serving
such notice and this Lease shall then expire on the date so specified as if that
date had been originally fixed as the expiration date of the term herein
granted; however, a default under Article 17.1 (2) hereof shall be deemed waived
if such default is made good before the date specified for termination in the
notice of termination served on the Tenant.
          17.3  In case this Lease shall be terminated as hereinbefore provided,
or by summary proceedings or otherwise, Landlord or its agents may, immediately
or any time thereafter, re-enter and resume possession of the Leased Premises or
such part thereof, and remove all persons and property therefrom, either by

                                       21
<PAGE>

summary proceedings or by a suitable action or proceeding at law, without being
liable for any damages therefor. No re-entry by landlord shall be deemed an
acceptance of a surrender of this lease.
          17.4  In case this lease shall be terminated as hereinafter provided,
or by summary proceedings or otherwise, Landlord may, in its own name and in its
own behalf, relet the whole or any portion of the Leased Premises, for any
period equal to or greater or less than the remainder of the then current term,
for any sum which it may deem reasonable, to any tenant which it may deem
suitable and satisfactory, and for any use and purpose which it may deem
appropriate, and in connection with any such lease Landlord may make such
changes in the character of the improvements on the Leased Premises as Landlord
may determine to be appropriate or helpful in effecting such lease, and Landlord
may grant concessions or free rent. Landlord agrees that it will take reasonable
steps to mitigate Tenant's damages. It is specifically understood and agreed
that Landlord, by listing the Leased Premises for lease with a recognized real
estate broker doing business in the Lawrenceville, New Jersey area, shall be
conclusively deemed to have utilized reasonable efforts to mitigate Tenant's
damages. Landlord shall not in any event be required to pay Tenant any surplus
of any sums received by Landlord on a reletting of the Leased Premises in excess
of the rent reserved in this Lease.
          17.5  (1) In case this lease be terminated by summary proceedings or
otherwise, as provided in this Article 17, and whether or not the Leased
Premises be relet, Landlord shall be entitled to recover from the Tenant, the
following:

                    (i)  a sum equal to all expenses, if any, including
     reasonable counsel fees, incurred by Landlord in recovering possession of
     the Leased Premises, and all reasonable costs and charges for the care of
     the Leased Premises while vacant, which damages shall be due and payable by
     Tenant to Landlord at such time or times as such expenses shall have been
     incurred by Landlord; and

                    (ii) a sum equal to all damages set forth in this Article 17
     and in Article 18.

                                       22
<PAGE>

          (2) Without any previous notice or demand, separate actions may be
maintained by Landlord against Tenant from time to time to recover any damages
which, at the commencement of any such action, have then or theretofore become
due and payable to the Landlord under this Article 17 and subsections hereof
without waiting until the end of the then current term.

          (3) All sums which Tenant has agreed to pay by way of adjustments to
rent or equitable adjustments in utility charges shall be deemed rent reserved
in this lease within the meaning of this Article 17 and subsections hereof.

          (4) Notwithstanding anything in this lease to the contrary, all
amounts payable by Tenant to or on behalf of Landlord under this lease, whether
or not expressly denominated as rent, shall constitute rent for the purposes of
section 502(b)(6) of the Bankruptcy Code, 11 U.S.C. Section 502(b)(6), or any
successor statute.

     18.  LIABILITY OF TENANT FOR DEFICIENCY
          ----------------------------------
          In the event that the relation of the Landlord and Tenant may cease or
terminate by reason of the default (beyond any applicable notice and cure
periods) by the Tenant and the re-entry of the Landlord as permitted by the
terms and conditions contained in this lease or by the ejectment of the Tenant
by summary proceedings or other judicial proceedings, or after the abandonment
of the Leased Premises by the Tenant, it is hereby agreed that the Tenant shall
remain liable to pay in monthly payments the rent which shall accrue subsequent
to the re-entry by the Landlord, and the Tenant expressly agrees to pay as
damages for the breach of the covenants herein contained the difference between
the rent reserved and the rent collected and received, if any, by the Landlord,
during the remainder of the unexpired term, as the amount of such difference or
deficiency shall from time to time be ascertained.

     19.  NOTICES
          -------

          The failure of either party to insist upon strict performance of any
of the covenants or conditions of this lease, or to exercise any option of the
Landlord or Tenant, as the case may be herein conferred in any one or more
instances, shall not be construed as a waiver by either party of any of their
respective rights or remedies in this Lease, and shall not be construed as a
waiver, relinquishment or failure of any such covenants, conditions, or options,
but the same shall be and remain in full force and effect.

     21.  RIGHT TO TENANT TO MAKE ALTERATIONS AND IMPROVEMENTS
          ----------------------------------------------------
          21.1  The Tenant may make alterations, additions or improvements to
the Leased Premises only with the prior written consent of the Landlord, which
consent shall not be unreasonably withheld, provided such alterations,
additions or improvements do not require structural changes in the Leased
Premises, or do not lessen the value of the Leased Premises. Any consent which
Landlord may give shall be conditioned upon Tenant furnishing to Landlord,
detailed plans and specifications with respect to any such changes, to be
approved by Landlord in writing. At the time of such consent, Landlord shall
notify Tenant if Tenant shall be required to remove, at Tenant's sole cost and
expense, any such alterations or additions by no later than the expiration of
the lease term. If Landlord does not require such removal, any such alterations
or additions shall be deemed to be part of the realty upon installation and
Tenant shall not be required to remove same. Landlord and Tenant hereby agree
that they shall conduct a walk

                                       24

Expiration Date of this lease, at which time Landlord shall confirm which
alterations and improvements, as aforesaid, will need to be removed by the
Tenant at Tenant's sole cost and expense, and which shall remain. All such
alterations, additions or improvements shall be only in conformity with

<PAGE>

     26.  FORCE MAJEURE
          -------------
          Except for the obligation of the Tenant to pay rent and other charges
as in this lease provided, the period of time during which the Landlord or

modifications, that the same is in full force and effect as modified and stating
the modifications) that it is not in default (or if claimed to be in default,
stating the amount and nature of the default) and specifying the dates to which
the basic rent and other charges have been paid in advance, if any; it being
intended that any such statement delivered pursuant to this Article may be
relied upon as to the facts contained therein.

     28.  CONDEMNATION
          ------------
          28.1  If due to the condemnation or taking or seizure by any authority
having the right of eminent domain, (i) more than fifteen (15%) percent of the
Leased Premises is taken or rendered untenantable, or (ii) in the event that
more than twenty-five (25%) percent of the ground allocated to the Building is
taken (including the parking areas, but exclusive of front, side and rear set
back areas), or (iii) if access to the Leased Premises be denied, which taking
in the manner hereinabove referred to and in excess of the

                                       27
<PAGE>

foregoing percentage amounts shall unreasonably or unduly interfere with the use
of the Building, ground area, parking area, or deny access to the Leased
Premises, then and in either of such events as hereinabove provided, the lease
term created shall, at the option of the Tenant, terminate, cease and become
null and void from the date when the authority exercising the power of eminent
domain takes or interferes with the use of the Building or the Leased Premises,
its use of the ground area, parking area, or area of access to the Leased
Premises. The Tenant shall only be responsible for the payment of rent until the
time of surrender. In any event, no part of the Landlord's condemnation award
shall belong to or be claimed by the Tenant. Without diminishing Landlord's
award, the Tenant shall have the right to make a claim against the condemning
authority for such independent claim which it may have and as may be allowed by
law, for costs and damages due to relocating, moving and other similar costs and
charges directly incurred by the Tenant and resulting from such condemnation.
          28.2  In the event of any partial taking which would not be cause for
termination of the within lease or in the event of any partial taking in excess
of the percentages provided in Article 28.1, and in which event the Tenant shall
elect to retain the balance of the Leased Premises remaining after such taking,
then and in either event, the rent shall abate in an amount mutually to be
agreed upon between the Landlord and Tenant based on the relationship that the
character of the property prior to the taking bears to the property which shall
remain after such condemnation. In any event, no part of the Landlord's
condemnation award shall belong to or be claimed by the Tenant. However, the
Landlord shall, to the extent permitted by applicable law and as the same may be
practicable on the site of the Leased Premises, at the Landlord's sole cost and
expense, promptly make such repairs and alterations in order to restore the
Building and/or improvements to usable condition to the extent of the
condemnation award.

     29.  LANDLORD'S REMEDIES
          -------------------
          29.1  The rights and remedies given to the Landlord in this lease are
distinct, separate and cumulative remedies, and no one of them, whether or not
exercised by the Landlord, shall be deemed to be in exclusion of any of the
others.

by or on the part of the Tenant or by any undertenant or by anyone holding or
claiming under the Tenant or any one of them, of the restrictions, agreements or

or custodian or debtors in possession shall reinstate, continue or extend the
term of this lease or affect any notice theretofore given to the Tenant, or to
any such receiver, trustee, custodian or debtor in possession, or operate as a
waiver or estoppel of the right of the Landlord to recover possession of the
Leased Premises for any of the causes therein enumerated by any lawful remedy;
and the failure of the Landlord to enforce any covenant or condition by reason
of its breach by the Tenant shall not be deemed to void or affect the right of
the Landlord to enforce the same covenant or condition on the occasion of any
subsequent default or breach.
          29.4  Tenant agrees that it shall reimburse Landlord for Landlord's
reasonable attorney's fees incurred in enforcing the terms and conditions of
this lease on the part of the Tenant to be performed. Tenant further agrees to
reimburse Landlord for Landlord's attorney's fees incurred in connection with

Leased Premises to the Landlord peaceably, together with all alterations,
additions and improvements in, to or on the Leased Premises made by Tenant as
permitted under the lease. The Landlord reserves the right, however, to require
the Tenant at its cost and expense to remove any alterations or improvements
installed by the Tenant, which covenant shall survive the surrender and the
delivery of the Leased Premises as provided hereunder. Prior to the expiration
of the lease term the Tenant shall remove all of its property, fixtures,
equipment and trade fixtures from the Leased Premises. All property not removed
by Tenant shall be deemed abandoned by Tenant, and Landlord reserves the right
to charge the reasonable cost of such removal to the Tenant, which obligation
shall survive the lease termination and surrender hereinabove provided. If the
Leased Premises be not surrendered at the end of the lease term, Tenant shall
indemnify Landlord against loss or liability resulting from delay by Tenant in
surrendering the Leased Premises, including, without limitation any claims made
by any succeeding tenant founded on the delay.

     32.  INDEMNITY
          ---------
          Anything in this Lease to the contrary notwithstanding, and without
limiting the Tenant's obligation to provide insurance pursuant to Article 10
hereunder but subject to the provisions of Article 10.3, the Tenant covenants

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

lease as a condition to such financing, Tenant will not unreasonably withhold,
delay or refuse its consent thereto, provided that such modifications do not in

hereby created or Tenant's use and enjoyment of the Leased Premises.

     38.  COVENANT AGAINST LIENS

encumbrance, and Tenant shall have no authority to mortgage or hypothecate this
lease in any way whatsoever. Any violation of this Article shall be considered a
breach of this lease.

     39.  SUBORDINATION
          -------------

          This lease shall be subject and subordinate at all times to the lien
of any mortgages or ground leases or other encumbrances now or hereafter placed
on the land Complex without the necessity of any further instrument or act on
the part of Tenant to effectuate such subordination, but Tenant covenants and
agrees to execute and deliver upon demand such further instrument or instruments
evidencing such subordination of the lease to the lien of any such mortgage or
ground lease or other encumbrances as shall be desired by a mortgagee or
proposed mortgagee or by any person. Tenant appoints Landlord the attorney-in-
fact of the Tenant irrevocably, to execute and deliver any such instrument or
instruments for and in the name of Tenant. Notwithstanding the foregoing,

obligations expressed herein may be enforced only against Landlord's interest in
the Complex, and the rents, issues and profits thereof, and the Tenant agrees
that no deficiency judgment or other judgment for money damages shall in any
event be entered by it against the Landlord or its principals personally in any
action; provided, however, that the provisions of this paragraph shall in no way
affect Tenant's other remedies for the payment of any indebtedness or for the
enforcement of Landlord's covenants under this lease.

portion of the Leased Premises without Landlord's prior consent, which consent
shall not be unreasonably withheld, subject to Landlord's rights hereinafter
provided in Article 43.4. Landlord may withhold such consent if, in the
reasonable exercise of its judgment, it determines that any of the following
enumerated conditions are applicable:

                (a) the proposed assignee's or subtenant's financial condition
is not sufficient to meet its obligations undertaken in such assignment or
sublease;

                (b) the proposed use of the Leased Premises is not appropriate
for the Complex and in keeping with the character of its existing tenancies;

                                       34
<PAGE>

          (c)  such assignee's or subtenant's occupancy will cause an excessive
density of traffic or make excessive demands on the Building's services,
maintenance or facilities;

          (d)  such assignee or subtenant is a tenant of and is vacating
premises in the Building, the Complex or any other building owned by or through
the persons constituting Landlord hereunder, including any corporation in which
Landlord's principals are majority stockholders, and any affiliates,
subsidiaries or parent of such corporation;

          (e)  the rental obligation of such assignee or subtenant would be less
than Tenant's rental obligations hereunder; or

          (g)  Landlord wishes to accept the offer as provided in Article 43.4.

          43.2 Any request by Tenant for Landlord's consent to an assignment of
the lease shall state the proposed assignee's address and be accompanied by a
profit and loss and balance statements of the proposed assignee for the prior
three (3) years, as well as duplicate original of the instrument of assignment
(wherein the assignee assumes, jointly and severally with Tenant, the
performance of Tenant's obligations hereunder).

          43.3 Any request by Tenant for Landlord's consent to a sublease shall
state the proposed subtenant's address and be accompanied by profit and loss and
balance statements of the proposed subtenant for the prior three (3) years, as
well as a duplicate original of the instrument of sublease (wherein Tenant and
the proposed subtenant agree that such sublease is subject to the lease and such
subtenant agrees that, if the lease is terminated because of Tenant's default,
such subtenant shall, at Landlord's option, attorn to Landlord).

          43.4 Any request by Tenant for Landlord's consent to an assignment of
the lease or a sublease of all or substantially all of the Leased Premises shall
clearly set forth the proposed terms of such proposed assignment or sublease and
shall constitute

                                       35
<PAGE>

Tenant's offer to cancel the lease. Landlord may accept such offer by notice to
Tenant within ninety (90) days after Landlord's receipt thereof, in which event,
the lease shall terminate as of the end of the month following the month in
which such notice is sent (with the same effect as if such date were the date
fixed herein for the natural expiration of the term), Base Rent and Additional
Rent shall be apportioned to such date, Tenant shall surrender the Leased
Premises on such date as herein provided, and subject to payment of required
lease adjustments, the parties shall thereafter have no further liability one to
the other. If Landlord fails to send such notice, Tenant, within twenty (20)
days after the expiration of such ninety (90) day period, may assign the lease
or sublet all or substantially all of the Leased Premises to the proposed
assignee or subtenant and upon the terms specified in such request, subject,
however, to Landlord's rights under Article 43.1(a) through (f).

          43.5  In the event of a permitted assignment, Landlord may collect
Base Rent and Additional Rent directly from the assignee. In the event of a
permitted sublease, Landlord may, if Tenant defaults hereunder, collect Base
Rent and Additional Rent directly from the subtenant. In either such event,
Landlord may apply any amounts so collected to the Base Rent and Additional Rent
hereunder without thereby waiving any provisions hereof or releasing Tenant from
liability for the performance of its obligations hereunder. In any event, Tenant
shall pay to Landlord, as Additional Rent, amounts received by Tenant from any
assignee or subtenant, in excess of the pro rata (per square foot) Base Rent and
Additional Rent payable by Tenant hereunder. All reasonable expenses incurred by
Tenant in connection with the sublease or assignment (including, without
limitation, reasonable attorney's fees and brokerage commissions) shall be
deducted from the amounts received by Tenant from the assignee or subtenant in
determining the extent by which such amounts exceed the Base Rent.

<PAGE>

               43.6  Landlord's consent to any assignment or sublease hereunder
shall not be deemed a consent to any further proposed assignment or sublease by
Tenant or any one claiming under or through the Tenant, except in accordance
with this Article 43.

               43.7  It is expressly understood and agreed that Tenant's Option
to Renew, as hereinafter set forth in Article 44, shall be personal to Tenant
only, and may not be exercised by any permitted assignee or subtenant hereunder
except in the event of an assignment or sublet permitted pursuant to Article
44.8 hereof.. It is understood and agreed that Tenant's Option to Renew shall be
null and void in the event that fifty (50%) percent or more of the Leased
Premises have been sublet by the Tenant prior to the date set for the exercise
by Tenant of the Option to Renew hereinafter set forth.

               43.8  Landlord's consent shall not be required and the terms and
conditions of Article 43.1 shall not apply as to Landlord's right of first
refusal to recapture if the Tenant assigns this lease or subleases the Leased
Premises to a parent, subsidiary, affiliate or company into which Tenant is
merged, upon which Tenant is consolidated or to the purchaser of all or
substantially all of the assets of Tenant.

     48.  EXECUTION AND DELIVERY
          ----------------------

          The submission of the within lease by Landlord to Tenant for review
and approval shall not be deemed an option to lease, an offer to lease, or a
reservation of the Leased Premises in favor of Tenant, it being intended that no

     AGREEMENT OF LEASE made as of this 4th day of December, 1997, between
FIRST PAC LIMITED, a Delaware corporation having an address c/o The Bank of Nova
Scotia, One Liberty Plaza, New York, New York 10006 Attention: Tenant Services
(hereinafter referred to as "Landlord") and AGORA DIGITAL CORPORATION, a
California corporation having an address at 221 Main Street, San Francisco,
California 94105 (hereinafter referred to as "Tenant").

                                  WITNESSETH:

     The parties hereby covenant and agree as follows:

                                   ARTICLE 1

                                      RENT

     1.01.     (a)  Landlord hereby leases and Tenant hereby rents from Landlord
a portion of the twenty-second (22nd) floor, approximately as shown hatched on
the plan annexed hereto as Schedule A (hereinafter referred to as the "demised
premises") in the building (hereinafter referred to as the "Building") located
on the land (hereinafter referred to as the "Land") described in Schedule B
annexed hereto (the Land and the Building being hereinafter referred to as the
"Property"), for a term (hereinafter referred to as the "Term") of approximately
three (3) years commencing on the "Commencement Date" and ending on the
"Expiration Date" (as said terms are defined in Article 2 hereof) unless the
Term shall sooner cease and terminate as hereinafter provided. It is expressly
understood and agreed that the Building has no floor which is denominated as the
13th floor.

               (b) Tenant agrees to pay to Landlord a fixed annual rent
(hereinafter referred to as the "fixed annual rent") at the annual rate of ONE
HUNDRED FOUR THOUSAND ONE HUNDRED FIFTEEN AND 00/100 ($104,115.00) DOLLARS per
annum, in equal monthly installments of Eight Thousand Six Hundred Seventy-Six
and 25/100 ($8,676.25) Dollars, each in advance on the first day of each
calendar month during the Term, at the office of Landlord or such other place as
Landlord may designate, without any setoff or deduction whatsoever, except such
deductions as are specifically referred to in Articles 10 and 14 hereof. The
first full month's installment of fixed annual rent and the Security Deposit
(described in Article 40 hereof) shall be paid by Tenant to Landlord upon the
execution of this Lease. Should the Commencement Date fall on any day other than
the first day of a month, then the fixed annual rent for such month shall be
prorated on a per diem basis, and Tenant agrees to pay the amount thereof for
such partial month on the Commencement Date.

     1.02.     Tenant shall pay the fixed annual rent and all additional rent
payable hereunder in lawful money of the United States by check (subject to
collection) drawn to the order of First Pac Limited, or such other party as
Landlord may from time to time designate, on a
<PAGE>

bank which is a member of The New York Clearinghouse Association or a successor
thereto. All sums, other than fixed annual rent, payable by Tenant hereunder
shall be deemed additional rent and shall be payable on demand unless other
payment dates are hereinafter provided. Landlord shall have the same rights and
remedies (including, without limitation, the right to commence a summary
proceeding) for a default in the payment of additional rent as for a default in
the payment of fixed annual rent notwithstanding the fact that Tenant may not
then also be in default in the payment of fixed annual rent.

     1.03.     (a)  If Tenant shall fail to pay when due (i) any installment of
fixed annual rent or (ii) any additional rent and any such failure shall
continue for five (5) days, then Tenant shall pay Landlord, as additional rent,
a late charge equal to two (2%) percent of such installment or payment as an
agreed liquidated amount as compensation for Landlord's additional
administrative expenses relating to such late payment. The provisions of this
subsection 1.03(a) shall not apply to the first failure by Tenant to pay any
such overdue rental item during any 12-month period occurring during the term of
this Lease provided Tenant shall cure such failure within five (5) Business Days
after notice thereof from Landlord.

               (b)  If Tenant shall fail to pay when due (i) any installment of
fixed annual rent or (ii) any additional rent when due and such failure shall
continue beyond the five (5) day period specified in paragraph (a) above, Tenant
shall pay in addition to the late charge provided in paragraph (a) above,
interest on such amounts at the Interest Rate (as such term is defined in
Article 22 hereof), from the last day of such five-day period to the date the
same is paid to Landlord, and such interest shall be deemed additional rent.

               (c)  The provisions of this Section 1.03 are in addition to other
remedies available to Landlord for non-payment of fixed annual rent or
additional rent.

     1.04.     If any of the fixed annual rent or additional rent payable under
this Lease shall be or become uncollectible, reduced or required to be refunded
because of any Legal Requirement (as such term is defined in Article 22 hereof),
Tenant shall enter into such agreement(s) and take such other legally
permissible steps as Landlord may reasonably request to permit Landlord to
collect the maximum rents which from time to time during the continuance of such
Legal Requirement may be legally permissible and not in excess of the amounts
reserved therefor under this Lease. Upon the termination of such Legal
Requirement, (a) the rents hereunder shall be payable in the amounts reserved
herein for the periods following such termination and (b) Tenant shall pay to
Landlord, to the maximum extent legally permissible, an amount equal to (i) the
rents which would have been paid pursuant to this Lease but for such Legal
Requirement less (ii) the rents, if any, paid by Tenant during the period such
Legal Requirement was in effect.

     1.05.     Provided that Tenant is not then in default of any of the terms,
provisions or conditions of this Lease, the fixed annual rent payable by Tenant
pursuant to Section 1.01(b) hereof shall be abated during the thirty (30) day
period commencing on the Commencement Date and ending on the date which shall be
the twenty-ninth (29th) day immediately following

                                       2
<PAGE>

the Commencement Date, both dates inclusive. The day which immediately follows
the expiration of the foregoing abatement period shall hereinafter be referred
to as the "Rent Commencement Date".

                                   ARTICLE 2

                             COMMENCEMENT OF TERM

     2.01.     (a)  The "Commencement Date" of the Term shall be the earlier of
(i) the date on which Landlord's Work is or is deemed to be substantially
completed (as hereinafter provided), or (ii) the date Tenant or anyone claiming
under or through Tenant first occupies the demised premises for the conduct of
its business.

               (b)  The "Expiration Date" of the Term shall be the last day of
the month in which occurs the third (3rd) anniversary of the Commencement Date.

     2.02.     (a)  Tenant has examined the demised premises and agrees to
accept same on the Commencement Date in the condition in which it exists on the
date hereof, subject to the performance of Landlord's Work (as such term is
hereinafter defined), and understands and agrees that no work is to be performed
or materials to be supplied by Landlord in connection with preparing the demised
premises for Tenant's occupancy, except that Landlord shall, through contractors
engaged by Landlord at a cost to Landlord which shall not exceed $31,550.00
(hereinafter called the "Work Credit"), make and complete "Landlord's Work" (as
such term is hereinafter defined) in accordance with the final architectural,
mechanical, electrical and engineering drawings (collectively, the "Final
Plans") to be prepared by an architect selected by Landlord based on the
preliminary plans annexed hereto as Schedule G, so that the Final Plans will
encompass working construction drawings which reflect the scope and quantity of
work set forth in such preliminary plans. Tenant agrees to cooperate with
Landlord in the preparation of the Final Plans and shall promptly meet with
Landlord, if so requested by Landlord, and to timely respond to Landlord's
request for information necessary in order to prepare such Final Plans. In
connection with the performance of Landlord's Work, Landlord shall deliver to
Tenant a copy of an ACP-5 Certificate with respect to the demised premises.

     To the extent that the cost of Landlord's Work (including, without
limitation, the cost of preparing and filing the Final Plans and obtaining all
necessary governmental permits and approvals in connection therewith) shall
exceed the amount of the Work Credit, Tenant shall be entirely responsible for
such excess (the "Excess Amount"). As a condition to the performance of, and
prior to the commencement of, Landlord's Work, Tenant shall pay to Landlord, as
additional rent hereunder, within three (3) Business Days after demand therefor,
the Excess Amount (subject to adjustment as hereinafter provided). To the extent
that any item of Landlord's cost cannot be precisely ascertained prior to the
commencement of Landlord's Work, Landlord shall be permitted to reasonably
estimate the same and at such times during or after the performance of
Landlord's Work as such costs may be determined precisely, the Excess Amount
shall be adjusted accordingly. If, after the actual costs of Landlord's Work
have been

                                       3
<PAGE>

ascertained, there has been an underpayment by Tenant of the Excess Amount,
Tenant shall pay the amount of such underpayment to Landlord within three (3)
Business Days after demand therefor, and if there has been an overpayment
thereof, Landlord agrees to refund such amount to Tenant promptly after such
costs have been ascertained. If Tenant fails to timely pay any such underpayment
to Landlord within the foregoing time period, any delays in the performance of
Landlord's Work ensuing thereafter shall be attributable to Tenant as provided
in subsection 2.07(b). Landlord agrees that the following costs associated with
Landlord's Work shall be borne solely by Landlord: (i) costs incurred to remove
any asbestos or asbestos-containing materials from the demised premises or the
surrounding area; (ii) restoration costs in excess of insurance proceeds as a
consequence of casualties; (iii) off-site management or other general overhead
costs incurred by Landlord; and (iv) construction management, profit and
overhead charges in excess of five (5%) percent of the total cost of Landlord's
Work.

     To the extent that the Final Plans do not specify any construction items,
materials or finishes in connection with the performance of Landlord's Work,
Landlord shall use such items, materials and finishes previously adopted by
Landlord in its sole discretion as standard for the Building.

     (b) The Final Plans shall be submitted by Landlord's Construction Manager
to Tenant for Tenant's approval, which approval shall not be unreasonably
withheld or delayed. In the event that Tenant shall fail to approve the Final
Plans (or shall fail to respond to Landlord's request for approval of same)
within five (5) Business Days after the date of the submission thereof, the
Final Plans shall be deemed disapproved and all delays thereafter ensuing until
Tenant shall approve said Final Plans shall be attributable to Tenant as
hereinafter provided in Section 2.07(b) hereof. If Tenant shall respond to
Landlord's request for approval of the Final Plans within the foregoing 5-
Business Day period but shall request changes thereto, any delays ensuing from
such request for changes until the Final Plans shall be approved by Tenant shall
be attributable to Tenant as set forth in Section 2.07(b) hereof.

     It is understood and agreed that Landlord may refuse to make any revisions
to the Final Plans requested by Tenant to the extent that the same would require
(i) materials, designs, capacities, finishes and colors other than of the
standard adopted by Landlord for the Building or commonly utilized by Landlord
for tenant installations in the Building (all of the foregoing are hereinafter
referred to as "Building Standard"), (ii) work or materials which do not comply
with all laws, rules and regulations of all public authorities having
jurisdiction in the Building with respect to Landlord's Work, (iii) the
performance of "Special Work" (as hereinafter defined), or (iv) work or
materials which shall adversely affect the ability of the building systems to
function properly. In the event that Landlord refuse requested changes to the
Final Plans solely for the reason set forth in clause (i) or (iii) of this
Section 2.02(b), Tenant shall have the right to override such action by Landlord
provided that Tenant shall assume, by written notice to Landlord, responsibility
for all delays of Landlord's Work resulting therefrom, and any such delays shall
be deemed to have resulted from an act of Tenant within the meaning of Section
2.07(b) of this Lease.

                                       4
<PAGE>

     It is further agreed that if Landlord shall be delayed in substantially
completing Landlord's Work as a result of: (i) Tenant's changes in the Final
Plans, (ii) any request by Tenant that Landlord delay the completion of any
Landlord's Work, (iii) any negligent or wrongful act of Tenant or its officers,
agents, servants or contractors, (iv) the inclusion in the Final Plans of
"Special Work" (as such term is hereinafter defined), or (v) any other act or
omission of Tenant, then any such delay shall be deemed to have resulted from
the act or omission of Tenant within the meaning of Section 2.07(b) of this
Lease.

     (c) After Tenant has approved the Final Plans in accordance with subsection
2.02(b) above, Landlord or Landlord's Construction Manager shall promptly seek
at least three (3) bids for Landlord's Work for such trades where three (3) such
contractors are practicably available for bidding, from such contractors as
Landlord's Contractor shall select, except that Landlord shall not be obligated
to obtain bids for the following subtrades: life safety, sprinklering, and fire
detection systems and any work in a subtrade for which the aggregate cost is
less than $5,000. Landlord shall have no liability if any of the contractors
shall fail to timely submit a bid. Landlord's Contractor may select such bidder
that it believes will do the best job in the most timely manner. After Landlord
shall have completed the foregoing bidding process, Landlord shall submit to
Tenant for Tenant's review a statement of Landlord's Construction Manager
setting forth the projected cost of Landlord's Work for Tenant's approval, not
to be unreasonably withheld (herein called the "Construction Bid"). If Tenant
shall fail to approve the Construction Bid within five (5) Business Days after
submission thereof, the same shall be deemed disapproved by Tenant and all
delays thereafter ensuing until Tenant shall approve any such costs shall be
attributable to Tenant as hereinafter provided in subsection 2.07(b) hereof.

     In the event of disapproval, Landlord shall not be restricted from
continuing the approved portion of Landlord's Work to the extent such approved
portions are, under good construction practices, capable of being installed
prior to the installation of such disapproved portions of Landlord's Work; and
if such approved portions of Landlord's Work are thereafter removed and
replaced, the cost of such removal and replacement shall be deemed part of
Landlord's Work and paid for by Tenant to Landlord as provided in subsection
2.04 hereof.

     2.03.     Landlord shall make and complete in and to the demised premises
the work and installations (herein called "Landlord's Work") specified in the
Final Plans using contractors therefor selected by Landlord in its discretion.
Landlord shall permit a representative of Tenant to inspect the progress of the
performance of Landlord's Work at intervals appropriate to the state of
construction, to familiarize Tenant with the progress of Landlord's Work.
Landlord or Landlord's contractor shall prepare and file all required
architectural, mechanical and electrical drawings and obtain all necessary
permits.

     2.04.     [Intentionally omitted]

     2.05.     As used in this Article 2, the term "Special Work" shall mean (i)
work that is unusually complex, or (ii) work which requires the performance of
work, labor or services or the application of skills not generally utilized in
the performance of tenant improvement work

                                       5
<PAGE>

for normal office occupancy in comparable office buildings in New York City, or
(iii) work which requires labor or materials which are not readily available in
the New York City metropolitan area or (iv) work which takes longer to perform
or complete than Building Standard work.

     2.06.     Landlord shall, in accordance with the provisions of this Article
2, fix the Commencement Date and shall notify Tenant of the date so fixed. When
the Commencement Date has so been determined, the parties shall, within ten (10)
days thereafter, at either party's request therefor, execute a written agreement
confirming such date as the Commencement Date. Any failure of the parties to
execute such written agreement shall not affect the validity of the Commencement
Date as fixed and determined as aforesaid.

     2.07.     (a)  Landlord's Work shall be deemed substantially completed
notwithstanding the fact that minor or insubstantial details of construction,
mechanical adjustment, or decoration remain to be performed, the non-completion
of which do not materially interfere with Tenant's use of the demised premises.

     (b)  If the substantial completion of Landlord's Work shall be delayed due
to any act or omission of Tenant or any of its employees, agents or contractors,
Landlord's Work shall be deemed substantially completed on the date when it
would have so been but for such delay. If a delay in the substantial completion
of Landlord's Work or any substantial portion of such delay is the result of a
strike or other labor trouble, fire or other casualty, governmental preemption
or priorities or other controls in connection with a national or other public
emergency or shortages of fuel, supplies or labor resulting therefrom, or any
other cause beyond Landlord's reasonable control, and such delay would not have
occurred but for a delay described in the preceding provisions of this Section
2.07(b), such delay shall be deemed added to the delay described in this Section
2.07(b).

     2.08.     Subject to the terms and provisions of Section 2.07 hereof, if
and when Tenant shall take actual possession of the demised premises, it shall
be conclusively presumed that the same were in satisfactory condition as of the
date of such taking of possession, unless within ten (10) Business Days after
such date Tenant shall give Landlord notice (hereinafter called the "punchlist")
specifying the respects in which the same was not so performed or completed.
With respect to latent defects not visually discoverable by Tenant in such walk-
through inspection of the demised premises, Tenant shall give Landlord notice
thereof within forty-five (45) days after the Commencement Date specifying the
items which were not in satisfactory condition, which items would not be
disclosed in such walk-through inspection of the demised premises. Landlord
agrees to diligently complete all items set forth in the punchlist as soon as
reasonably practicable, at Landlord's sole cost and expense, provided that in no
event shall Landlord be required to perform the same on an overtime or premium-
pay basis.

     2.09.     In the event that Landlord has not substantially completed the
performance of Landlord's Work by the date (the "Outside Date") occurring one
hundred twenty (120)

                                       6
<PAGE>

days from the date that (i) Tenant shall have approved the Final Plans and the
cost of Landlord's Work and (ii) Landlord shall have obtained a building permit
from the New York City Building's Department and any required governmental
permits and approvals associated therewith (which Outside Date shall be extended
on a day-for day basis for each day that Landlord is delayed in substantially
completing Landlord's Work by reason of strikes, labor disputes, acts of God or
other circumstances constituting Force Majeure Causes, or by any act or omission
of Tenant, its employees, agents or contractors as defined in Section 2.07(b)
hereof), then Landlord shall have no liability to Tenant and provided and on
condition that as of the Outside Date Tenant shall not have taken occupancy of
any part of the demised premises, Tenant, as its sole remedy, shall have the
right to terminate this Lease by written notice given to Landlord within ten
(10) Business Days after the Outside Date (as such date may be extended as
hereinbefore provided) and such termination shall be effective on the date
occurring thirty (30) days from the date of the giving of Tenant's termination
notice unless the Commencement Date occurs within such thirty (30) day period.
If Tenant exercises such option to terminate this Lease, then upon such
termination, neither Landlord nor Tenant shall have any further obligations to
the other hereunder except that Landlord shall promptly thereafter return to
Tenant all sums theretofore paid by Tenant to Landlord hereunder.

                                   ARTICLE 3

                              ADJUSTMENTS OF RENT

     3.01 A.   For purposes hereof, the following definitions shall apply:

               (a) The term "Base Tax" shall mean the "Taxes" (as hereinafter
defined) for the Tax Year commencing July 1, 1997, as finally determined.

               (b) The term "Tax Year" shall mean each period of twelve months
which includes any part of the Term which now or hereafter is or may be duly
adopted as the fiscal year for real estate tax purposes of the City of New York.

               (c) The term "Taxes" shall means all real estate taxes,
assessments, governmental levies, municipal taxes, county taxes or any other
governmental charge, general or special, ordinary or extraordinary, unforeseen
as well as foreseen, of any kind or nature whatsoever, which are or may be
assessed, levied or imposed upon all or any part of the Property and the
sidewalks, plazas or streets adjacent thereto, including any tax, excise or fee
measured by or payable with respect to any rent (other than any occupancy or
rent tax payable by Tenant pursuant to Section 3.03), and levied against
Landlord and/or the Property under the laws of the United States, the City or
State of New York, or any political subdivision thereof. There shall be excluded
from the definition of the term "Taxes" any tax or assessement or any increase
therein (i) in excess of the amount which would be payable if such tax or
assessment were paid out over the longest possible term; (ii) imposed on land
and improvements other than the Property, except as otherwise expressly set
forth in this subsection 3.01.A(c), and (iii)

                                       7
<PAGE>

attributable to Landlord's franchise, income, transit, or profit taxes;
provided, however, if due to a future change in the method of taxation or in the
taxing authority, a new or additional real estate tax, or a franchise, income,
transit, profit or other tax or governmental imposition, however designated,
shall be levied against Landlord, and/or the Property, in addition to, or in
substitution in whole or in part for any tax which would constitute "Taxes", or
in lieu of additional Taxes, such tax or imposition shall be deemed for the
purposes hereof to be included within the term "Taxes."

               (d) The term "Tenant's Tax Share" shall mean 0 799%.

               (e) The term "Escalation Statement" shall mean a statement
setting forth the amount payable by Tenant for a specified Tax Year or Operating
Year (as defined in Section 3.02 hereof), as the case may be, or for some
portion thereof pursuant to this Article 3.

          B.   Tenant shall pay to Landlord as additional rent for each Tax
Year a sum equal to Tenant's Tax Share of the amount by which the Taxes for such
Tax Year exceed the Base Tax (hereinafter referred to as "Tenant's Tax
Payment"). Landlord shall furnish to Tenant an annual Escalation Statement
(subject to revision as hereinafter provided) for each Tax Year setting forth
Tenant's Tax Payment for such Tax Year. Tenant's Tax Payment shall be due and
payable in two (2) equal installments, in advance, on the first day of each June
and December of each Tax Year based upon the Escalation Statement furnished with
respect to such Tax Year, until such time as a new Escalation Statement for a
subsequent Tax Year shall become effective. If an annual Escalation Statement is
furnished to the Tenant after the commencement of the Tax Year to which it
relates, then Tenant shall, within 20 days after such annual Escalation
Statement is furnished to Tenant, pay to Landlord an amount equal to any
underpayment of Tenant's Tax Payment theretofore paid by Tenant for such Tax
Year and, in the event of an overpayment by Tenant, Landlord shall permit Tenant
to credit against subsequent rental payments under this Lease the amount of such
overpayment. If there shall be any increase in Taxes for any Tax Year, whether
during or after such Tax Year, Landlord shall furnish a revised Escalation
Statement for such Tax Year to Tenant, and Tenant's Tax Payment for such Tax
Year shall be adjusted and paid or credited, as appropriate, in the same manner
as provided in the preceding sentence. If during the Term, Taxes are required to
be paid (either to the appropriate taxing authorities or as tax escrow payments
to the holder of a Superior Instrument (as defined in Section 25.01 hereof) in
full or in monthly, quarterly, or other installments, on any other date or dates
than as presently required, then at Landlord's option, Tenant's Tax Payments
shall be correspondingly accelerated or revised so that said Tenant's Tax
Payments are due at least 30 days prior to the date payments are due to the
taxing authorities or the superior mortgagee or ground lessor. The benefit of
any discount for any early payment or prepayment of Taxes shall accrue solely to
the benefit of Landlord and such discount shall not be subtracted from Taxes.

          C.   If Landlord shall receive a refund a taxes for any Tax Year,
Landlord shall permit Tenant to credit against subsequent rental payments under
this Lease,


                                       8
<PAGE>

Tenant's Tax Share of the refund, but not in excess of, Tenant's Tax Payment
paid for such Tax Year.

          D.   If the Taxes comprising the Base Tax are reduced as a result of
an appropriate proceeding or otherwise, the Taxes as so reduced shall, for all
purposes be deemed to be the Taxes for the Base Tax and Landlord shall give
notice to Tenant of the amount by which the Tax Payments previously made were
less than the Tax Payments required to be made under this Article 3, and Tenant
shall pay the amount of the deficiency within ten (10) days after demand
therefor.

          E.   Tenant shall pay as additional rent hereunder within ten (10)
days after delivery of a statement therefor for each Tax Year Tenant's Tax Share
of any expenses incurred by Landlord, including payments to attorneys,
accountants and appraisers, in contesting any items of Taxes or the assessed
valuations of all or any part of the Property.

    3.02. A.   For purposes hereof the following definitions shall apply:

               (a) The term "Expense Base Factor" shall mean the Expenses for
the Operating Year commencing January 1, 1997.

               (b) The term "Operating Year" shall mean each calendar year which
includes any part of the Term.

               (c) The term "Tenant's Expense Share" shall mean 0.799%.

               (d) The term "Expenses" shall mean the total of all the costs and
expenses (and taxes thereon, if any) incurred by Landlord with respect to the
operation and maintenance of the Property and the services provided to the
tenants of the Building computed on an accrual basis including, without
limitation, the costs and expenses with respect to: steam, gas and any other
fuel or utilities; water rates and sewer rents, vault charges; air conditioning;

such improvements shall not include improvements expanding the size of the
Building); and management fees for the management of the Building, or if no
managing agent is employed by Landlord, a sum in lieu thereof which is not in
excess of the then prevailing rates for management fees in the Borough of
Manhattan for first-class office buildings similar to the Building. If under
general accounting principles consistently applied, any of the costs included
within Expenses are required to be capitalized, then such capitalized costs
together with interest thereon at the Interest Rate then in effect as of
December 31 of the year in which such expenditure is made, shall be amortized or
depreciated, as the case may be, over a period of time which shall be the
shorter of: (A) the useful life of the item in question, as reasonably
determined by Landlord, or (B) ten (10) years.

     The following costs and expenses shall be excluded or deducted, as
appropriate, from Expenses:

or other casualty or condemnation to the extent to which Landlord is compensated
therefor through proceeds of insurance or condemnation award;

<PAGE>

               (vi)   advertising and promotional expenditures other than for
prospective employees of the Landlord (which expenditures shall be included
within the definition of Expenses);

               (vii)  Taxes;

               (viii) costs for performing Landlord's Work for any individual

improvements made in or to the Building or the demised premises to cure
conditions which constitute currently existing violations of Legal Requirements
(as defined in Article 22 hereof) to the extent that same are in effect as of

financings, refinancings, or sales or in connection with enforcing the
provisions of any tenant's lease, other than a tenant who is disturbing other
tenants in the Building;

               (xiii) interest, charges and fees incurred on debt, except to
the extent expressly otherwise set forth herein; and

               (xiv) any other expenditure which would otherwise be an Expense
to the extent Landlord is reimbursed therefor by condemnation award or insurance
proceeds or by tenant refund (other than reimbursement by reason of escalation
type clauses in tenants' leases comparable to this Article 3).

     If during all or part of any Operating Year including Operating Year 1997,
Landlord shall not furnish any particular item(s) of work or service (which
would constitute an Expense hereunder) to portions of the Building, due to the
fact that construction of the Building is not completed, or such portions are
not occupied or leased, or because such item of work or service is not required
or desired by the tenant of such portion, or such tenant is itself obtaining and
providing such item of work or service, or for other reasons, then, for the
purpose of computing the additional rent payable hereunder, the amount otherwise
includible in Expenses


                                       11
<PAGE>

for such item for such period shall be increased by an amount equal to the
additional operating and maintenance expenses which would reasonably have been
incurred during such period by Landlord if it had at its own expense furnished
such item of work or services to such portion of the Building.

          B.   If the Expenses for any Operating Year exceed the Expense Base
Factor, Tenant shall pay to Landlord as additional rent for such Operating Year
an amount equal to Tenant's Expense Share of the excess of the Expenses for such
Operating Year over the Expense Base Factor (hereinafter referred to as
"Tenant's Expense Payment").

          C.   Landlord shall furnish to Tenant for each Operating Year an
Escalation Statement (subject to revision as hereinafter provided) setting forth
Landlord's estimate of Tenant's Expense Payment for such Operating Year. Tenant
shall pay to Landlord on the first day of each month during such Operating Year
an amount equal to one-twelfth (1/12) of Landlord's estimate of Tenant's Expense
Payment for such Operating Year. If Landlord shall furnish such estimate for an
Operating Year after the commencement thereof, then (a) until the first day of
the month following the month in which such estimate is furnished to Tenant,
Tenant shall pay to Landlord on the first day of each month an amount equal to
the monthly sum payable by Tenant to Landlord under this Paragraph C for the
last month of the preceding Operating Year; (b) Landlord shall notify Tenant in
the Escalation Statement containing such estimate whether the installments of
Tenant's Expense Payment previously paid for such Operating Year were more or
less than the installments which should have been paid for such Operating Year
pursuant to such estimate and (i) if there shall be an underpayment, Tenant
shall pay the amount thereof within twenty days after being furnished with such
Escalation Statement or (ii) if there shall be an overpayment, Tenant shall be
entitled to a credit in the amount thereof against subsequent rental payments
under this Lease; and (c) on the first day of the month following the month in
which such estimate is furnished to Tenant and monthly thereafter for the
balance of such Operating Year, Tenant shall pay to Landlord an amount equal to
one-twelfth (1/12) of Tenant's Expense Payment as shown on such estimate.
Landlord may at any time and from time to time (but not more often than three
times in any Operating Year) furnish to Tenant an Escalation Statement setting
forth Landlord's revised estimate of Tenant's Expense Payment for a particular
Operating Year and Tenant's Expense Payment for such Operating Year shall be
adjusted and paid or credited, as applicable, in the same manner as provided in
the preceding sentence.

          D.   After the end of each Operating Year Landlord shall submit to
Tenant an annual Escalation Statement prepared by Landlord setting forth the
Expenses for the preceding Operating Year and the balance of Tenant's Expense
Payment, if any, due to Landlord from Tenant for such Operating Year. If such
annual Escalation Statement shall show that the sums paid by Tenant under
subparagraph 3.02(C) above exceeded Tenant's Expense Payment for such Operating
Year, Tenant shall be entitled to a credit in the amount of such excess against
subsequent rental payments under this Lease. If such annual Escalation Statement
shall show that the sums so paid by Tenant were less than Tenant's Expense
Payment for such Operating

                                       12
<PAGE>

Year, Tenant shall pay the amount of such deficiency to the Landlord within ten
days after being furnished with such annual Escalation Statement.

            E.   The annual Escalation Statements with respect to Expenses to be
furnished by Landlord as provided above shall be in reasonable detail but need
not be audited or certified. Landlord may use operating cost allocations and
estimates if such allocations or estimates are required for this Section 3.02.

     3.03.  Tenant shall pay to Landlord upon demand, as additional rent, any
occupancy tax or rent tax hereafter enacted, which Landlord is hereafter
required to pay with respect to the demised premises or this Lease.

     3.04.  If the Commencement Date shall be other than the first day of a Tax
Year or an Operating Year or if the date of the expiration or other termination
of this Lease shall be a day other than the last day of a Tax Year or an
Operating Year, then Tenant's Tax Payment and/or Tenant's Expense Payment for
such partial year shall be equitably adjusted taking into consideration the
portion of such Tax Year or Operating Year falling within the Term. Landlord
shall, as soon as reasonably practicable, cause an Escalation Statement with
respect to Taxes for the Tax Year and/or Expenses for the Operating Year in
which the Term expires to be prepared and furnished to Tenant. Such Escalation
Statement shall be prepared as of the expiration date of the Term if such date
is December 31, and if not, as of the first to occur of June 30 or December 31
after the expiration date of the Term. Landlord and Tenant shall thereupon make
appropriate adjustments of amounts then owing.

     3.05.  In no event shall the fixed annual rent ever be reduced by operation
of this Article 3. The rights and obligations of Landlord and Tenant under the
provisions of this Article 3 shall survive the termination of this Lease, and
payments shall be made pursuant to this Article 3 notwithstanding the fact that
an Escalation Statement is furnished to Tenant after the expiration or other
termination of the Term.

     3.06.   Landlord's failure to render an Escalation Statement with respect
to any Tax Year or Operating Year shall not prejudice Landlord's right to
thereafter render an Escalation Statement with respect thereto or with respect
to any subsequent Tax Year or Operating Year.

     3.07.  Each Escalation Statement shall be conclusive and binding upon
Tenant unless within 30 days after receipt of such Escalation Statement Tenant
shall notify Landlord that it disputes the correctness of such Escalation
Statement, specifying the particular respects in which such Escalation Statement
is claimed to be incorrect. Any dispute relating to any Escalation Statement,
not resolved within 30 days after the giving of such notice by Tenant, may be
submitted to arbitration by either party pursuant to Article 37 hereof. Pending
the determination of such dispute, Tenant shall pay additional rent in
accordance with the Escalation Statement that Tenant is disputing, without
prejudice to Tenant's position.

                                   ARTICLE 4

                                  ELECTRICITY

     4.01.     Landlord agrees that prior to the Commencement Date risers,
feeders and wiring will be installed in the Building by Landlord to furnish
electrical service to the demised premises in accordance with the provisions of
this Article 4. After the Commencement Date any additional risers, feeders or
other equipment or service proper or necessary to supply Tenant's electrical
requirements, upon written request of Tenant, will be installed by Landlord at
the sole cost and expense of Tenant, if in Landlord's reasonable judgment the
same are necessary and will not cause permanent damage or injury to the Building
or the demised premises or cause or create a dangerous or hazardous condition or
entail excessive or unreasonable alterations, repairs or expense or interfere
with or disturb other tenants or occupants.

     4.02.     For the period commencing on the Commencement Date, Tenant
covenants and agrees to contract directly with and to pay directly to the
utility company supplying electric current for the demised premises the amounts
due for such electric current consumed as indicated by meters measuring Tenant's
consumption thereof.

     4.03.     (a)  For the period commencing on the Commencement Date, if one
meter measures the consumption of electric current by Tenant and another lessee
of space in the Building (i.e., more than two tenants on a floor), or if there
is no meter measuring Tenant's consumption of electric current for any purpose,
including without limitation, air conditioning, ventilating and heating (e.g.,
more than one tenant on a floor with respect to air conditioning and
ventilating), Tenant agrees to pay to Landlord or Landlord's designated agent
charges for electric current consumed by Tenant as determined by Landlord's
electric consultant in accordance with Section 4.08 hereof. Bills therefor, at
the rate charged to Landlord for such electric current, plus the amount of sales
tax imposed thereon by any Governmental Authority, plus 5% of the total amount
thereof for administration and processing, shall be rendered at such times as
Landlord may elect based upon estimates of Landlord's electric consultant which
may be made from time to time as Landlord deems necessary. Until such time as
Landlord's electrical consultant first makes its estimate as aforesaid, Tenant
shall pay as its electricity charge hereunder (exclusive of HVAC Electricity (as
hereinafter defined) the sum of $3.00 per square foot per annum multiplied by
the rentable square footage of the demised premises (the "Base Charge") which
shall be payable in equal monthly installments together with the Tenant's
payments of fixed annual rent hereunder on the first day of each calendar month.
In the event Landlord's consultant shall determine that Tenant's electricity
charge should exceed the Base Charge, Tenant's Base Charge shall be adjusted
retroactively at such time as Landlord's electrical consultant's determination
is made. Any deficiency for such prior period shall be payable upon demand. In
no event shall the Base Charge be reduced pursuant to the terms hereof. Tenant
shall permit Landlord's electrical consultant to make surveys in the demised
premises from time to time during normal business hours regarding the electrical
equipment and fixtures and the use of electric current therein.


                                       14
<PAGE>

          (b) In the event the Tenant occupies a portion of a floor, with
respect to the electric current used (i) to run the air conditioning system on
Tenant's floor, including without limitation, for purposes of "early morning
warm-up" and (ii) for the lighting of the common areas on Tenant's floor,
Landlord shall charge Tenant its proportionate share of such charge plus sales
tax and the administrative fees referred to above based upon the proportion
which the rentable area of the demised premises bears to the rentable area of
that portion of the floor which is subject to leases whose terms have commenced.

          (c) If Tenant pays for electric current consumed pursuant to
subsection (a) above, Landlord reserves the right to discontinue furnishing
electric energy to Tenant at any time that electric service may be obtained by
Tenant directly from the public utility company servicing the Building upon
thirty (30) days' prior written notice to Tenant, and from and after the
effective date of such termination, Landlord shall no longer be obligated to
furnish Tenant with electric energy, provided, however that such termination
date shall be extended for such time as is reasonably necessary for Tenant to
make arrangements to obtain electric service directly from the public utility
company servicing the Building. If Landlord exercises such right of termination,
this Lease shall remain unaffected thereby and shall continue in full force and
effect; and thereafter Tenant shall diligently arrange to obtain electric
service directly from the public utility company servicing the Building.

     4.04.     Tenant's use of electric current in the demised premises shall
not at any time exceed the capacity of any of the electrical conductors and
equipment in or otherwise serving the demised premises.

     4.05.     To the extent permitted by applicable law, Landlord shall not be
liable in any way to Tenant for any failure or defect in the supply or character
of electric energy furnished to the demised premises by reason of any
requirement, act or omission of the public utility providing the Building with
electricity or for any other reason whatsoever.

     4.06.     At Landlord's option, Tenant shall purchase from Landlord or
Landlord's agent all lighting tubes, lamps, bulbs and ballasts used in the
demised premises and Tenant shall pay Landlord's reasonable charges for
providing and installing same on demand as additional rent.

     4.07.     Intentionally Omitted.

     4.08.     Any determinations with respect to charges for electricity on
floors occupied by more than one tenant or otherwise which must be made pursuant
to the terms of this Lease shall be made by a reputable, independent electrical
consultant selected by Landlord ("Landlord's electrical consultant"). Any
determination made by Landlord's electrical consultant pursuant to or in
connection with this Lease shall be binding and conclusive on Landlord and on
Tenant unless Tenant disputes such determination as hereinafter provided. Tenant
shall have the right to give a notice (the "Dispute Notice") to Landlord within
30 days after the date it is notified of any determination by Landlord's
electrical consultant that (i) Tenant has engaged its

                                       15
<PAGE>

own electrical consultant ("Tenant's electrical consultant") to verify the
determination of Landlord's electrical consultant. If Tenant's electrical
consultant and Landlord's electrical consultant cannot agree within ten (10)
days after the Dispute Notice, if any, is given on what an appropriate
resolution of their dispute should be, then either party, upon notice to the
other, may submit the issue to arbitration in accordance with the provisions of
Article 37 of this Lease, the reasonable cost of any such arbitration (but not
the fees and expenses of Landlord's attorneys) to be borne solely by Tenant in
the event such dispute relates to a determination with respect to electricity
provided to a portion of the Building other than the demised premises. While
such dispute is being resolved, Tenant shall pay such charges and payments as
would be due hereunder if Landlord's electrical consultant's determination were
correct without prejudice to Tenant's position. In the event it is finally
determined that there has been an overpayment by Tenant, such overpayment shall
be credited against future rent payments due from Tenant under the Lease and in
the event of an underpayment, the amount of such underpayment by Tenant shall be
paid by Tenant to Landlord within 20 days after such determination is made.

                                   ARTICLE 5

                                      USE

     5.01.     The demised premises shall be used solely as and for executive
and general offices, and, as ancillary uses to office use, provided same do not
violate the Certificate of Occupancy, for software sales (but not retail sales
on an off-the-street basis), marketing, customer service, technical support,
research and development, and consulting services, and for no other purpose.

     5.02.     Tenant shall not use or permit the use of the demised premises or
any part thereof in any way which would violate any of the terms and conditions
of this Lease or for any unlawful purposes or in any unlawful manner or in
violation of the Certificate of Occupancy for the demised premises or the
Building, and Tenant shall not permit the demised premises or any part thereof
to be used in any manner or anything to be done, brought into or kept therein
which, in Landlord's judgment shall impair or interfere with (i) the character,
reputation or appearance of the Building as a high quality office building, (ii)
any of the Building services or the proper and economic heating, cleaning, air
conditioning or other servicing of the Building or the demised premises, or
(iii) the use of any of the other areas of the Building by, or occasion
discomfort, inconvenience or annoyance to, any of the other tenants or occupants
of the Building.

                                   ARTICLE 6

                         ALTERATIONS AND INSTALLATIONS

     6.01.     Tenant shall make no alterations, installations, additions or
improvements (other than purely decorative items such as painting and carpeting)
in or to the demised premises without Landlord's prior written consent and then
only by contractors or mechanics first recommended and approved by Landlord,
such approval as to contractors and mechanics not to be unreasonably withheld or
delayed. All such work, alterations, installations, additions and improvements
shall be done at Tenant's sole expense and at such times and in such manner as
Landlord may from time to time designate in its reasonable judgment.

     All work in the demised premises shall be done solely in accordance with
plans and specifications first approved in writing by Landlord. Tenant shall
reimburse Landlord promptly upon demand for any costs and expenses incurred by
Landlord in connection with Landlord's review of such Tenant's plans and
specifications. Landlord will not unreasonably withhold or delay its consent to
requests for nonstructural alterations, additions and improvements (provided
they will not interfere with the operation of the Building nor affect the
outside of the Building nor adversely affect its structure, or its electrical,
HVAC, plumbing or mechanical systems).

     Any such approved alterations and improvements shall be performed in
accordance with the foregoing and the following provisions of this Article 6:

          1.   All work shall be done in a good and workmanlike manner.

          2.   (a)  Any contractor employed by Tenant to perform any work
     permitted by this Lease, and all of its subcontractors, shall agree to
     employ only such labor as will not result in jurisdictional disputes or
     strikes or cause disharmony with other workers employed at the Building.
     Tenant will inform Landlord in writing of the names of any contractor or
     subcontractors Tenant proposes to use in the demised premises at least ten
     (10) days prior to the beginning of work by such contractor or
     subcontractors.

               (b) Tenant covenants and agrees to pay to the contractor, as the
     work progresses, the entire cost of supplying the materials and performing
     the work shown on Tenant's approved plans and specifications; subject only
     to customary retentions.

          3.   All such alterations shall be performed in compliance with all
     Legal Requirements (as defined in Article 22 hereof).

          4.   Tenant shall keep the Building and the demised premises free and
     clear of all liens for any work or material claimed to have been furnished
     to

                                       17
<PAGE>

     Tenant or to the demised premises on Tenant's behalf, and all work to be
     performed by Tenant shall be done in a manner which will not unreasonably
     interfere with or disturb other tenants or occupants of the Building.

          5.   During the progress of the work to be done by Tenant, said work
     shall be subject to inspection by representatives of Landlord who shall be
     permitted access and the opportunity to inspect, at all reasonable times,
     but this provision shall not in any way whatsoever create any obligation on
     Landlord to conduct such an inspection or constitute approval by Landlord
     of such work or subject Landlord to liability for the manner of
     performance.

          6.   Tenant agrees to pay to Landlord's managing agent, as additional
     rent, promptly upon being billed therefor, a sum equal to Landlord's
     actual, out-of-pocket costs incurred on account of Landlord's indirect
     costs, field inspection and coordination in connection with such work.

          7.   Prior to commencement of any work, Tenant shall furnish to
     Landlord certificates evidencing the existence of:

                    (a) Worker's compensation insurance covering all persons
          employed for such work with statutorily required limits; and

                    (b) Employer's liability coverage including bodily injury
          caused by disease with limits of not less than $100,000 per employee;

                    (c) Comprehensive general liability insurance including but
          not limited to completed operations coverage, products liability
          coverage, contractual coverage, broad form property damage,
          independent contractor's coverage and personal injury coverage naming
          (i) Landlord as well as such representatives and consultants of
          Landlord as Landlord shall reasonably specify (collectively
          "Landlord's Consultants"), including, but not limited to, as of the
          date hereof Insignia/Edward S. Gordon Company, Inc. and The
          Shorenstein Company, as well as Tenant, as additional insureds, with
          coverage of not less than $3,000,000 combined single limit coverage
          (or such higher limits as Landlord may from time to time impose in its
          reasonable judgment);

                    (d) Tenant shall require all contractors engaged or employed
          by the Tenant to indemnify and hold Tenant, Landlord, and Landlord's
          Consultants, including but not limited to, as of the date hereof

          modifications therein as may be required from time to time by reason
          of a change in the parties constituting Landlord's Consultants):

<PAGE>

               "The contractor hereby agrees to the fullest extent permitted by
               law to assume the entire responsibility and liability for and
               defense of and to pay and indemnify the Landlord, Tenant, and
               Landlord's Consultants against any loss, cost, expense, liability
               or damage and will hold each of them harmless from and pay any
               loss, cost, expense, liability or damage (including, without
               limitation, judgments, attorney's fees, court costs, and the cost
               of appellate proceedings), which the Landlord and/or Tenant
               and/or Landlord's Consultants incurs because of injury to or
               death of any person or on account of damage to property,
               including loss of use thereof, or any other claim arising out of,

               Landlord's Consultants, its or their employees or agents or any
               other person."

               The contractor's insurance shall specifically insure the
               foregoing hold harmless provision verbatim.

                    (e) Such insurance shall be placed with solvent and
          responsible companies reasonably satisfactory to the Landlord and
          licensed or authorized to do business in the State of New York, and
          the policies shall provide that they may not be cancelled without 30
          days' prior notice in writing to the Landlord.

     6.02      Notice is hereby given that Landlord shall not be liable for any
labor or materials furnished or to be furnished to Tenant upon credit, and that
no mechanic's or other lien for any such labor or materials shall attach to or
affect the reversion or other estate or interest of Landlord in and to the
demised premises. Any mechanic's lien, filed against the demised premises or the
Building for work claimed to have been done for or materials claimed to have
been furnished to Tenant shall be discharged by Tenant at its expense within
thirty (30) days after such filing, by payment, filing of the bond required by
law or otherwise. Failure to comply with the provisions of this Section 6.02
shall constitute a material default by Tenant under this Lease entitling
Landlord to exercise any or all of the remedies provided in this Lease in the
event of Tenant's default.

     6.03.     All alterations, installations, additions and improvements made
and installed by Landlord, at its expense, shall be the property of Landlord and
shall remain upon and be surrendered with the demised premises as a part thereof
at the end of the Term.

     6.04.     All alterations, installations, additions and improvements made
and installed by Tenant, or at Tenant's expense, upon or in the demised premises
which are of a permanent nature and which cannot be removed without damage to
the demised premises or Building including, without limitation, any so-called
"raised flooring" or supplementary air conditioning units, shall become the
property of Landlord, and shall remain upon and be surrendered with the demised
premises as a part thereof at the end of the Term (and shall not be removed
prior thereto without Landlord's written consent), except that Landlord shall
have the right at any time up to six months prior to the expiration of the Term
to serve notice upon Tenant that any of such alterations, installations,
additions and improvements, except for Landlord's Work, which are of a non-
Building Standard office nature such as vaults, auditoriums, kitchens and the
like, shall be removed and, in the event of service of such notice, Tenant will,
at Tenant's own cost and expense, remove the same in accordance with such
request, and repair any damage to the demised premises caused by such removal.

     6.05.     Where furnished by or at the expense of Tenant all furniture,
furnishings and trade fixtures (exclusive of raised flooring), but including
without limitation, murals, business machines and equipment, counters, screens,
grille work, cages, partitions, metal railings, closets, free standing lighting
fixtures and equipment, drinking fountains, and any other moveable property not
connected to the demised premises or the Building's systems shall remain the
property of Tenant which may at its option remove all or any part thereof at any
time prior to the expiration of the Term. In case Tenant shall decide not to
remove any part of such property, Tenant shall notify Landlord in writing not
less than three (3) months prior to the expiration of the Term, specifying the
items of property which it has decided not to remove. If, within thirty (30)
days after the service of such notice, Landlord shall request Tenant to remove
any of the said property, Tenant shall at its expense remove the same. As to
such property which Landlord does not request Tenant to remove, the same shall
be, if left by Tenant, deemed abandoned by Tenant and thereupon the same shall
become the property of Landlord.

     6.06      If any alterations, installations, additions, improvements or
other property which Tenant shall have the right to remove or be requested by
Landlord to remove as provided in Sections 6.04 and 6.05 hereof (herein in this
Section 6.06 called the "property") are not removed on or prior to the
expiration of the Term, Landlord shall have the right to remove the property and
to dispose of the same without accountability to Tenant and at the sole cost and
expense of Tenant. In case of any damage to the demised premises or the Building
resulting from the removal of the property Tenant shall repair such damage or,
in default thereof, shall reimburse Landlord for Landlord's cost in repairing
such damage. This obligation shall survive any termination of this Lease.

     6.07.     Tenant shall keep records of Tenant's alterations, installations,
additions and improvements costing in excess of $10,000, and of the cost
thereof. Tenant shall, within 15 days after demand by Landlord, furnish to
Landlord copies of such records if Landlord shall require same in connection
with any proceeding to reduce the assessed valuation of the Building, or in
connection with any proceeding instituted pursuant to Article 14 hereof.

                                    REPAIRS

     7.01.     Tenant shall, at its sole cost and expense, make such repairs to
the demised premises and the fixtures and appurtenances therein as are
necessitated by the act, omission, occupancy or negligence of Tenant or by the
use of the demised premises in a manner contrary to the purposes for which same
are leased to Tenant, as and when needed to preserve them in good working order
and condition. Except as otherwise provided in Section 9.05 hereof, all damage
or injury to the demised premises and to its fixtures, appurtenances and
equipment caused by Tenant moving property in or out of the Building or by
installation or removal of furniture, fixtures or other property, shall be
repaired, restored or replaced promptly by Tenant at its sole cost and expense,
which repairs, restorations and replacements shall be in quality and class equal
to the original work or installations. If Tenant fails to make such repairs,
restoration or replacements, same may be made by Landlord at the expense of
Tenant and such expense shall be collectible as additional rent and shall be
paid by Tenant within 10 days after rendition of a bill therefor.

     The exterior walls of the Building, the portions of any window sills
outside the windows and the windows are not part of the premises demised by this
Lease and Landlord reserves all rights to such parts of the Building.

     7.02      Tenant shall not place a load upon any floor of the demised
premises exceeding the floor load per square foot of area which such floor was
designed to carry. Such floor is designed for the following superimposed
loading:

Total Tenant Load                                     82 pounds per square foot


     7.03.     Business machines and mechanical equipment used by Tenant which
cause vibration, noise, cold or heat that may be transmitted to the Building
structure or to any leased space to such a degree as to be objectionable to
Landlord or to any other tenant in the Building shall be placed and maintained
by Tenant at its expense in settings of cork, rubber or spring type vibration
eliminators sufficient to absorb and prevent such vibration or noise, or prevent
transmission of such cold or heat. The parties hereto recognize that the
operation of elevators, air conditioning and heating equipment will cause some
vibration, noise, heat or cold which may be transmitted to other parts of the
Building and demised premises. Landlord shall be under no obligation to endeavor
to reduce such vibration, noise, heat or cold beyond what is customary in
current good building practice for buildings of the same type as the Building.

     7.04.     Except as otherwise specifically provided in this Lease, there
shall be no allowance to Tenant for a diminution of rental value and no
liability on the part of Landlord by reason of inconvenience, annoyance or
injury to business arising from the making of any repairs, alterations,
additions or improvements in or to any portion of the Building or the demised
premises or in or to fixtures, appurtenances or equipment thereof. Landlord
shall exercise reasonable diligence so as to minimize any interference with
Tenant's business operations, but shall not be required to perform the same on
an overtime or premium pay basis.

     7.05.     Except as otherwise provided in this Lease, Landlord shall,
throughout the Term, keep and maintain in good order and condition the following
items, but only to the extent that such items affect the use and enjoyment of
the demised premises for the conduct of Tenant's business: (a) the lobbies,
common corridors, sidewalks and other common elements of the Building; (b) the
roof, exterior, load-bearing columns, and foundation of the Building, and (c)
the systems of the Building including elevators, HVAC, plumbing, electrical and
other Building systems and equipment servicing the demised premises to the point
of entry into the demised premises, provided however that Landlord shall not be
liable for any defects or deficiencies thereof which shall be caused by Tenant's
equipment, alterations or installations, or which shall result from any act or

                              REQUIREMENTS OF LAW

     8.01  Tenant shall comply with all Legal Requirements (including, without
limitation, the Disabilities Act, as defined in Section 22.04 hereof) which
shall impose any violation, order or duty upon Landlord or Tenant with respect
to the demised premises, or the use or occupation thereof; provided, however,
that Tenant shall not be required to make structural alterations in order to
effect such compliance unless the need therefor shall result from, or arise in
connection with (i) a negligent or wrongful act or omission of Tenant, its
agents, representatives, contractors or invitees, or (ii) a default under this
Lease by Tenant, or (iii) Tenant's particular manner of use of the demised
premises, or (iv) any alterations performed by, or on behalf of, Tenant in the
demised premises (excluding Landlord's Work). Tenant shall pay all the costs,
expenses, fines, penalties and damages which may be imposed upon Landlord by
reason of or arising out of Tenant's failure to fully and promptly comply with
and observe the provisions of this Section.

     8.02  Notwithstanding the provisions of Section 8.01 hereof, Tenant, at its
own cost and expense, in its name and/or (whenever necessary) Landlord's name,
may contest, in any manner permitted by law (including appeals to a court, or
governmental department or authority having jurisdiction in the matter), the
validity or the enforcement of any Legal Requirements with which Tenant is
required to comply pursuant to this Lease, and may defer compliance therewith
provided that:

           (a)  such non-compliance shall not subject Landlord to criminal
prosecution or subject the Property to lien or sale (without limiting the
application of the above, Landlord shall be deemed subject to prosecution for a
crime if Landlord, or its managing agent, or any officer, director, partner,
shareholder or employee of Landlord or its managing agent as an individual, is
charged with a crime of any kind or degree whatever, whether by summons or
otherwise);

           (b)  such non-compliance shall not be in violation of any mortgage,
or of any ground or underlying lease or any mortgage thereon;

           (c)  Tenant shall first deliver to Landlord a surety bond issued by a
surety company of recognized responsibility, or other security satisfactory to
Landlord, indemnifying and protecting Landlord against any loss or injury by
reason of such non-compliance; and

           (d)  Tenant shall promptly, diligently and continuously prosecute
such contest.

     Without limiting the applications of the above, Landlord shall be deemed
subject to prosecution for a crime, if Landlord, or its managing agent, or any
officer, director, partner,

                                      23
<PAGE>

shareholder or employee of Landlord or its managing agent, as an individual, is
charged with a crime of any kind or degree whatever, whether by summons or
otherwise.

     Landlord, without expense or liability to it, shall cooperate with Tenant
and execute any documents or pleadings required for such purpose, provided that
Landlord shall reasonably be satisfied that the facts set forth in any such
documents or pleadings are accurate.

                                  ARTICLE 9.

                   INSURANCE, LOSS, REIMBURSEMENT, LIABILITY

     9.01.  Tenant shall not do or permit to be done any act or thing upon or
about the demised premises which will (i) result in the assertion of any defense
by the insurer to any claim under, (ii) invalidate or (iii) be in conflict with
the policies covering the Building, and fixtures and property therein, or which
would increase the rate of fire insurance applicable to the Building to an
amount higher than it otherwise would be; and Tenant shall neither do nor permit
to be done any act or thing upon or about the demised premises or the Building
which shall or might subject Landlord to any liability or responsibility for
injury to any person or persons or to property; but nothing in this Section 9.01
shall prevent Tenant's use of the demised premises for the purposes stated in
Article 5 hereof.

     9.02.  If, as a result of any act or omission by or on the part of Tenant
or violation of this Lease, whether or not Landlord has consented to the same,
the rate of "all risk" or other type of insurance maintained by Landlord on the
Building and fixtures and property therein, shall be increased to an amount
higher than it otherwise would be, Tenant shall reimburse Landlord for all
increases of such insurance premiums so caused; such reimbursement to be
additional rent payable within 20 days after demand therefor by Landlord. In any
action or proceeding wherein Landlord and Tenant are parties, a schedule or
"make-up" of rates for the Building or demised premises issued by the body
making fire insurance rates or established by insurance carrier providing
coverage for the Building or demised premises, shall be conclusive evidence of
the facts stated therein including the items and charges taken into
consideration in fixing the "all risk" insurance rate then applicable to the
Building or demised premises.

     9.03.  Landlord, Landlord's Consultants, or their agents, servants or
employees shall not be liable for any injury or damage to persons or property
resulting from fire, explosion, falling plaster, steam, gas, electricity, water,
rain or snow or leaks from any part of the Building, or from the pipes,
appliances or plumbing works or from the roof, street or subsurface or from any
other place or resulting from dampness or resulting from any other cause of
whatsoever nature, unless (but only to the extent) any of the foregoing shall be
caused by or due to the negligence of Landlord, its agents, servants or
employees. Notwithstanding the preceding provisions of this Section 9.03, Tenant
covenants, and agrees that (i) any rights of Tenant to make a claim against
Landlord, Landlord's Consultants, or their agents, servants or employees as
contemplated herein shall be subject to the waiver of subrogation provisions set
forth in

                                      24
<PAGE>

Article 9.08 of this Lease, and (ii) in no event shall Tenant be entitled to
make a claim for consequential, indirect or special damages pursuant to this
Section 9.03.

     9.04.  Landlord, Landlord's Consultants, or their agents shall not be
liable for any damage which Tenant may sustain, if at any time any window of the
demised premises is broken, or temporarily or permanently closed, darkened or
bricked upon for any reason whatsoever, except only Landlord's arbitrary acts if
the result is permanent, and Tenant shall not be entitled to any compensation
therefor or abatement of rent or to any release from any of Tenant's obligations
under this Lease, nor shall the same constitute an eviction or constructive
eviction.

     9.05.  Tenant shall reimburse Landlord and Landlord's Consultants, for all
expenses, damages or fines incurred or suffered by Landlord or Landlord's
Consultants, by reason of any breach, violation or non-performance by Tenant, or
its agents, servants or employees, of any covenant or provision of this Lease,
or by reason of damage to persons or property caused by moving property of or
for Tenant in or out of the Building, or by the installation or removal of
furniture or other property of or for Tenant, or by reason of or arising out of
the carelessness, negligence or improper conduct of Tenant, or its agents,
servants or employees, in the use or occupancy of the demised premises. Tenant
shall have the right, at Tenant's own cost and expense, to participate in the
defense of any action or proceeding brought against Landlord or Landlord's
Consultants and in negotiations for settlement thereof if, pursuant to this
Section 9.05, Tenant would be obligated to reimburse Landlord or Landlord's
Consultants for expenses, damages or fines incurred or suffered by Landlord or
Landlord's Consultants.

     9.06.  Tenant shall give Landlord notice in case of fire or accidents in
the demised premises promptly after Tenant is aware of such event.

     9.07.  (a)  No recourse shall be had on any of Landlord's obligations
hereunder or for any claim based thereon or otherwise in respect thereof against
any incorporator, subscriber to the capital stock, shareholder, officer or
director, past, present or future, of any corporation or any partner or joint
venturer which shall be Landlord hereunder or included in the term "Landlord" or
of any successor of any such corporation, or against any principal, disclosed or
undisclosed, or any affiliate of any party which shall be Landlord or included
in the term "Landlord," whether directly or through Landlord or through any
receiver, assignee, trustee in bankruptcy or through any other person, firm or
corporation, whether by virtue of any constitution, statute or rule of law or by
enforcement of any assessment or penalty or otherwise, all such liability being
expressly waived and released by Tenant.

            (b)  Tenant shall look solely to Landlord's estate and interest in
the Building for the satisfaction of any right of Tenant for the collection of a
judgment or other judicial process or arbitration award requiring the payment of
money by Landlord, and no other property or assets of Landlord, Landlord's
agents, incorporators, shareholders, officers, directors, partners, principals
(disclosed or undisclosed) or affiliates shall be subject to levy, lien,
execution, attachment, or other enforcement procedure for the satisfaction of
Tenant's rights and

                                      25
<PAGE>

remedies under or with respect to this Lease, the relationship of Landlord and
Tenant hereunder, or under law, or Tenant's use and occupancy of the demised
premises, or any other liability of Landlord to Tenant.

     9.08. (a)  Notwithstanding anything to the contrary contained in this
Lease, Tenant agrees that it will, at its sole cost and expense, include in its
property insurance policies appropriate clauses pursuant to which the insurance
companies (i) waive all right of suborgation against Landlord, Landlord's
Consultants, and any tenant of space in the Building with respect to losses
payable under such policies and (ii) agree that such policies shall not be
invalidated should the insured waive in writing prior to a loss any or all right
of recovery against any party for losses covered by such policies. Tenant shall
furnish Landlord upon demand evidence satisfactory to Landlord evidencing the
inclusion of said clauses in Tenant's property insurance policies.

           (b)  Provided that Landlord's right of full recovery under its
property insurance policies is not adversely affected or prejudiced thereby, and
so long as the waivers provided for in Section 9.08(a) remain in full force and
effect, Landlord hereby waives any and all right of recovery which it might
otherwise have against Tenant, its servants, agents and employees, for loss or
damage occurring to the Building and the fixtures, appurtenances and equipment
therein, to the extent the same would be covered by Landlord's insurance, as
required under Section 9.10 of this Lease whether or not such insurance is
maintained, notwithstanding that such loss or damage may result from the
negligence or fault of Tenant, its servants, agents or employees. Tenant hereby
waives any and all right of recovery which it might otherwise have against
Landlord, its servants, and employees, and against every other tenant in the
Building who shall have executed a similar waiver as set forth in this Section
9.08(b) for loss or damage to, Tenant's furniture, furnishings, fixtures and
other property removable by Tenant under the provisions hereof to the extent
that same would be covered by Tenant's insurance as required under this Lease
whether or not such insurance is maintained, notwithstanding that such loss or
damage may result from the negligence or fault of Landlord, its servants, agents
or employees, or such other tenant or the servants, agents or employees thereof.

     9.09. Tenant covenants and agrees to provide at its expense on or before
the Commencement Date and to keep in force during the Term naming Landlord, its
Agent, Landlord's Consultants and Tenant as insured parties (x) a comprehensive
general liability insurance policy or such successor comparable form of coverage
in the broadest form then available (hereinafter referred to as a "Liability
Policy") written on "an occurrence basis", including, without limitation,
blanket contractual liability coverage, broad form property damage, independent
contractor's coverage and personal injury coverage protecting Landlord,
Landlord's Consultants and Tenant against any liability whatsoever, occasioned
by any occurrence on or about the demised premises or any appurtenances thereto
and (y) a fire and other casualty policy (a "Fire Policy") insuring the full
replacement value of all Tenant's improvements and betterments installed by or
on behalf of Tenant after the Commencement Date and all of the furniture, trade
fixtures and other personal property of Tenant located in the demised premises
against loss or damage by fire, theft and such other risks or hazards as are

                                      26
<PAGE>

insurable under present and future forms of "All Risk" insurance policies, and
(z) policy of insurance against loss or damage to the major components of the
air conditioning and/or heating system, flywheels, steam pipes, steam turbines,
steam engines, steam boilers, other pressure vessels, high pressure piping and
machinery, if any, such as are installed by or on behalf of Tenant in the
demised premises. Such policies shall also insure against physical damage to the
demised premises arising out of an accident covered thereunder, such policies
are to be written by good and solvent insurance companies licensed to do
business in the State of New York satisfactory to Landlord, and shall be in such
limits and with such maximum deductibles as Landlord may reasonably require. As
of the date of this Lease, Landlord reasonably requires limits of liability
under (x) the Liability Policy of not less than $5,000,000 combined single limit
per occurrence for bodily or personal injury (including death) and property
damage combined; (y) under the Fire Policy equal to the value of all Tenant's
improvements and betterments and furniture, trade fixtures and other personal
property with a deductible of no more than $1,000,00; and (z) under machinery
insurance for full replacement cost of equipment with a deductible of no more
than $1,000.00. Tenant will furnish Landlord with such information as Landlord
may reasonably request from time to time as to the value of the items specified
in clause (y) above within ten (10) days after request therefor. Such insurance
may be carried under a blanket policy covering the demised premises and other
locations of Tenant, if any, provided that each such policy shall in all
respects comply with this Article and shall specify (i) that the portion of the
total coverage of such policy that is allocated to the demised premises is in
the amounts required pursuant to this Section 9.09 and (ii) any sublimits in
such blanket policy and such policy shall specify, or Tenant shall furnish
Landlord a written statement from the insurer under such policy that the
protection afforded Tenant under any such blanket policy shall be no less than
that which would have been afforded under a separate policy relating only to the
demised premises. Prior to the time such insurance is first required to be
carried by Tenant and thereafter, at least 15 days prior to the expiration date
of any such policy, Tenant agrees to deliver to Landlord a certificate
evidencing such insurance Said certificate shall contain an endorsement that
such insurance may not be cancelled or materially changed except upon 30 days'
prior written notice to Landlord. If, due to abandonment of, or failure to
occupy the demised premises by Tenant, any such insurance required to be carried
by Tenant shall be cancelled by the insurance carrier, then Tenant hereby
indemnifies Landlord against liability which would have been covered by such
insurance. Tenant's failure to provide and keep in force the aforementioned
insurance shall be regarded as a material default hereunder entitling Landlord
to exercise any or all of the remedies provided in this Lease in the event of
Tenant's default. Notwithstanding anything to the contrary contained in this
Lease, the carrying of insurance by Tenant in compliance with this Section shall
not modify, reduce, limit or impair Tenant's obligations and liability under
Article 38 hereof.

     9.10  Landlord covenants and agrees to provide at its expense from and
after the date on which this Lease is executed and delivered and thereafter so
long as this Lease remains in full force and effect a fire and casualty
insurance policy, with such limits and deductibles as shall be required by the
holder of the institutional first mortgage which is then a lien on the Building,
or if there shall be no such mortgage, the limits and deductibles that would
then generally be required by the holder of an institutional first mortgage on
the Building.

                                  ARTICLE 10

                         DAMAGE BY FIRE OR OTHER CAUSE

     10.01. If the Building or the demised premises shall be partially or
totally damaged or destroyed by fire or other cause (and if this Lease shall not
have been terminated as in this Article 10 hereinafter provided), (a) Landlord
shall, with reasonable dispatch after notice to it of the damage or destruction
and the collection of the insurance proceeds attributable to such damage, repair
the damage and restore and rebuild the Building and/or the demised premises,
such restoration of the demised premises to include Tenant's improvements and
betterments (but excluding Tenant's personal property) and (b) Tenant shall
repair the damage to and restore and repair Tenant's furniture, fixtures and
other personal property as set forth in clause (y) of Section 9.09 hereof with
reasonable dispatch after such damage or destruction. Such work by Tenant shall
be subject to all the provisions of this lease. The proceeds of policies
providing coverage for Tenant's improvements and betterments (which Tenant is
required to maintain pursuant to Section 9.09 hereof) shall be paid to Landlord,
and concurrently with the collection of any insurance proceeds attributable to
the damage of Tenant's improvements and betterments, Tenant shall pay to
Landlord (i) the amount of any deductible under the policy insuring Tenant's
improvements and betterments and (ii) the amount, if any, by which the cost of
repairing and restoring Tenant's improvements and betterments as estimated by a
reputable contractor designated by Landlord exceeds the available insurance
proceeds therefor. The amounts due in accordance with clauses (i) and (ii) of
the preceding sentence shall be additional rent under this lease and payable by
Tenant to Landlord upon demand.

     10.02. If the Building or the demised premises shall be damaged or
destroyed by fire or other cause, then the rents payable hereunder shall be
abated to the extent that the demised premises shall have been rendered
untenantable for the period from the date of such damage or destruction to the
date the damage shall be substantially repaired or restored; provided, however,
that should Tenant reoccupy a portion of the demised premises during the period
the restoration work is taking place and prior to the date that the whole of
said demised premises are made tenantable, fixed annual rent and additional
rents allocable to such portion shall be payable by Tenant from the date of such
occupancy.

     10.03. If the Building shall be so damaged or destroyed by fire or other
cause (whether or not the demised premises are damaged or destroyed) as to
require a reasonably estimated expenditure made by Landlord or a reputable
contractor designated by Landlord of more than 30% of the full insurable value
of the Building immediately prior to the casualty, then Landlord may terminate
this Lease by giving Tenant notice to such effect within 90 days after the date
of the casualty. In case of any damage or destruction to the demised premises
mentioned in this Article 10 which Landlord is required to repair and restore,
Tenant may terminate this Lease by notice to Landlord if Landlord has not
substantially completed the making of such required repairs and restorations
within (a) nine (9) months after the date of such damage or destruction if the
damage or destruction takes place on or before the first (1st) anniversary of
the Commencement Date, or within such period after the date nine (9) months

                                      28
<PAGE>

after the date of such damage or destruction (not exceeding 6 months) as shall
equal the aggregate period Landlord may have been delayed in doing so by Force
Majeure Causes (as defined in Article 34 hereof); (b) four (4) months after the
date of such damage or destruction if the damage or destruction takes place
after the first (1st) anniversary of the Commencement Date, or within such
period after the date four (4) months after the date of such damage or
destruction (not exceeding 6 months) as shall equal the aggregate period
Landlord may have been delayed in doing so by Force Majeure Causes; or (c) two
(2) months after the date of such damage or destruction if the damage or
destruction took place after the second (2nd) anniversary of the Commencement
Date, or within such period after the date two (2) months after the date of such
damage or destruction (not exceeding 6 months) as shall equal the aggregate
period Landlord may have been delayed in doing so by Force Majeure Causes.

     10.04. No damages, compensation or claim shall be payable by Landlord for
inconvenience, loss of business or annoyance arising from any repair or
restoration of any portion of the demised premises or of the Building pursuant
to this Article 10.

     10.05. Landlord will not carry separate insurance of any kind on Tenant's
property (including, without limitation, any property of the Tenant which shall
become the property of Landlord as provided in Article 6 hereof), and, except as
provided by law, Landlord shall not be obligated to repair any damage thereto or
replace or clean the same, or any other decorations, installations, equipment or
fixtures installed by or for Tenant at Tenant's expense. Tenant shall maintain
such fire and casualty insurance as it deems advisable, but not less than the
limits provided in clause (y) of Section 9.09 hereof. If Tenant shall fail to
maintain such insurance, Landlord shall have the right (but in no way shall
Landlord be obligated or in any way be adversely affected if Landlord fails or
elects not to do so) to obtain insurance on Tenant's property and the cost
thereof shall be additional rent under this Lease and payable by Tenant to
Landlord on demand.

     10.06. The provisions of this Article 10 shall be considered an express
agreement governing any case of damage or destruction of the demised premises by
fire or other casualty, and Section 227 of the Real Property Law of the State of
New York, providing for such a contingency in the absence of an express
agreement, and any other law of like import, now or hereafter in force, shall
have no application in such case.

                                  ARTICLE 11

                   ASSIGNMENT, MORTGAGING, SUBLETTING, ETC.

     11.01. Except as otherwise expressly provided in this Article 11, Tenant
shall not without, in each instance, obtaining the prior consent of Landlord,
(a) assign or otherwise transfer this Lease or the term and estate hereby
granted, (b) sublet all or part of the demised premises or allow the same to be
used or occupied by others or in violation of Article 5, (c) mortgage, pledge or
encumber this Lease or all or part of the demised premises in any

                                      29
<PAGE>

manner by reason of any act or omission on the part of Tenant, or (d) advertise,
or authorize a broker to advertise, for a subtenant for all or part of the
demised premises or for an assignee of this Lease. For purposes of this Article
11, (i) the transfer of a majority of the issued and outstanding capital stock
of any corporate tenant or subtenant, or the transfer of a majority of the total
interest in any other entity (partnership or otherwise) which is a tenant or
subtenant, however accomplished, whether in a single transaction or in a series
of related or unrelated transactions, shall not be deemed an assignment of this
Lease, or of such sublease, as the case may be, provided that such transfer was
not primarily for the purpose of transferring Tenant's leasehold interest
hereunder, (ii) any person or legal representative of Tenant, to whom Tenant's
interest under this Lease passes by operation of law, or otherwise, shall be
bound by the provisions of this Article 11, and (iii) a modification, amendment
or extension without Landlord's prior written consent of a sublease previously
consented to by Landlord shall be deemed a new sublease. Tenant agrees to
furnish to Landlord upon demand at any time and from time to time such
information and assurances as Landlord may reasonably request that neither
Tenant, nor any subtenant, shall have violated the provisions of this Section
11.01.

     11.02. The provisions of clauses (a) and (b) of Section 11.01 hereof shall
not apply to transactions entered into by Tenant with a corporation into or with
which Tenant is merged or consolidated or with an entity to which substantially
all of Tenant's assets are transferred, provided (a) such merger, consolidation
or transfer of assets is for a good business purpose and not principally for the
purpose of transferring the leasehold estate created hereby, and (b) the
assignee or successor entity has a net worth at least equal to or in excess of
the net worth of Tenant either (i) immediately prior to such merger,
consolidation or transfer or (ii) as of the date hereof, whichever is greater.

     11.03. Any assignment or transfer, whether made with Landlord's consent as
required by Section 11.01 or without Landlord's consent pursuant to Section
11.02, shall not be effective unless and until (a) the assignee shall execute,
acknowledge and deliver to Landlord a recordable agreement, in form and
substance reasonably satisfactory to Landlord, whereby the assignee shall (i)
assume the obligations and performance of this Lease and agree to be personally
bound by all of the covenants, agreements, terms, provisions and conditions
hereof on the part of Tenant to be performed or observed on and after the
effective date of any such assignment and (ii) agree that the provisions of this
Article 11 shall, notwithstanding such assignment or transfer, continue to be
binding upon it in the future, and (b) in the case of an assignment or transfer
pursuant to Section 11.02 Tenant or its successor shall have delivered to
Landlord financial statements certified by a reputable firm of certified public
accountants evidencing satisfaction of the net worth requirements referred to in
Section 11.02. Tenant covenants that, notwithstanding any assignment or
transfer, whether or not in violation of the provisions of this Lease, and
notwithstanding the acceptance of fixed annual rent by Landlord from an assignee
or transferee or any other party, Tenant shall remain fully and primarily and
jointly and severally liable for the payment of the fixed annual rent and all
additional rent due and to become due under this Lease and for the performance
and observance of all of the covenants, agreements, terms, provisions and
conditions of this Lease on the part of Tenant to be performed or observed.

                                      30
<PAGE>

     11.04. The liability of Tenant, and the due performance by Tenant of the
obligations on its part to be performed under this Lease, shall not be
discharged, released or impaired in any respect by an agreement or stipulation
made by Landlord or any grantee or assignee of Landlord, by way of mortgage, or
otherwise, extending the time of, or modifying any of the obligations contained
in this Lease, or by any waiver or failure of Landlord to enforce any of the
obligations on Tenant's part to be performed under this Lease, and Tenant shall
continue liable hereunder. If any such agreement or modification operates to
increase the obligations of a tenant under this Lease, the liability under this
Section 11.04 of the tenant named in the Lease or any of its successors in
interest (unless such party shall have expressly consented in writing to such
agreement or modification) shall continue to be no greater than if such
agreement or modification had not been made.

     11.05. Provided that Tenant is not in default of any of Tenant's
obligations under this Lease beyond the expiration of any applicable notice and
cure periods, Landlord shall not unreasonably withhold or delay its consent to
an assignment of this Lease or a subletting of the whole or a part of the
demised premises for substantially the remainder of the term of this Lease,
provided:

               (a)  Tenant shall furnish Landlord with the name and business
address of the proposed subtenant or assignee, information with respect to the

Landlord, and an executed counterpart of the sublease or assignment agreement;

               (b)  The proposed subtenant or assignee is a reputable party
whose financial net worth, credit and financial responsibility is, considering
the responsibilities involved, reasonably satisfactory to Landlord;

               (c)  The nature and character of the proposed subtenant or
assignee, its business or activities and intended use of the demised premises
are, in Landlord's reasonable judgment, in keeping with the standards of the
Building and the floor or floors on which the demised premises are located;

               (d)  Neither (i) the proposed subtenant or assignee nor (ii) any
person which, directly or indirectly, controls, is controlled by, or is under
common control with, the proposed assignee or subtenant, is then an occupant of
any part of the Building or a party who dealt with Landlord or Landlord's agent
(directly or through a broker) with respect to space in the Building during the
12 months immediately preceding Tenant's request for Landlord's consent;

               (e)  All costs incurred with respect to providing reasonably
appropriate means of ingress and egress from the sublet space or to separate the
sublet space

                                      31
<PAGE>

from the remainder of the demised premises shall, subject to the provisions of
Article 6 with respect to alterations, installations, additions or improvements,
be borne by Tenant;

               (f)  Each assignment or sublease shall specifically state that
(i) it is subject to all of the terms, covenants, agreements, provisions, and
conditions of this Lease, (ii) the subtenant or assignee, as the case may be,
will not have the right to further assign or sublet all or part of the demised
premises or to allow same to be used by others, without the consent of Landlord
in each instance, (iii) a consent by Landlord thereto shall not be deemed or
construed to modify, amend or affect the terms and provisions of this Lease, or
Tenant's obligations hereunder, which shall continue to apply to the premises
involved, and the occupants thereof, as if the sublease or assignment had not
been made, (iv) if Tenant defaults in the payment of any rent, Landlord is
authorized to collect any rents due or accruing from any assignee, subtenant or
other occupant of the demised premises and to apply the net amounts collected to

                 (1)  the aggregate of the fixed annual rent and the additional
            rent payable hereunder which would have been payable by Tenant
            (conclusively presuming the additional rent to be the same as was
            payable for the year immediately preceding such termination) for the
            period commencing with such earlier termination of this Lease or the
            date of any such re-entry, as the case may be, and ending with the
            Expiration Date, had this Lease not so terminated or had Landlord
            not so re-entered the demised premises, over

                 (2)  the aggregate rental value of the demised premises for the
            same period, or

            (b)  sums equal to the fixed annual rent and the additional rent
payable hereunder which would have been payable by Tenant had this Lease not so
terminated, or had Landlord not so re-entered the demised premises, payable upon
the due dates therefor specified herein following such termination or such re-
entry and until the Expiration Date, provided, however, that if Landlord shall
re-let the demised premises during said period, Landlord shall credit Tenant
with the net rents received by Landlord from such re-letting, such net rents to
be determined by first deducting from the gross rents as and when received by
Landlord from such re-letting, the expenses incurred or paid by Landlord in
terminating this Lease or in re-entering the demised premises and in securing
possession thereof, as well as the expenses of re-letting, including altering
and preparing the demised premises for new tenants, brokers' commissions, legal
fees, and all other expenses properly chargeable against the demised premises
and the rental thereof; it being understood that any such re-letting may be for
a period shorter or longer than the remaining term of this Lease. In no event
shall Tenant be entitled to receive any excess of such net rents over the sums
payable by Tenant to Landlord hereunder for the period of such re-letting, or
shall Tenant be entitled in any suit for the collection of damages pursuant to
this subsection to a credit in respect of any net rents from a re-letting,
except to the extent that such net rents are actually received by Landlord. If
the demised premises or any part thereof should be re-let in combination with
other space, then proper apportionment on a square foot basis shall

                                      42
<PAGE>

be made of the rent received from such re-letting and of the expenses of re-
letting. If the demised premises or any part thereof be re-let by Landlord for
the unexpired portion of the term of this Lease, or any part thereof, before
presentation of proof of such damages to any court, commission or tribunal, the
amount of rent payable pursuant to such re-letting shall, prima facie, be the
fair and reasonable rental value for the demised premises, or part thereof, so
re-let during the term of the re-letting.

     18.02.  Suit or suits for the recovery of such damages, or any installments
thereof, may be brought by Landlord from time to time at its election, and
nothing contained herein shall be deemed to require Landlord to postpone suit
until the date when the Term would have expired if it had not been so terminated
under the provisions of Article 16, or under any provision of law, or had
Landlord not re-entered the demised premises. Nothing herein contained shall be
construed to limit or preclude recovery by Landlord against Tenant of any sums
or damages to which, in addition to the damages particularly provided above,
Landlord may lawfully be entitled by reason of any default hereunder on the part
of Tenant. Nothing herein contained shall be construed to limit or prejudice the
right of Landlord to prove for and obtain as liquidated damages by reason of the
termination of this Lease or re-entry of the demised premises for the default of
Tenant under this Lease, an amount equal to the maximum allowed by any statute
or rule of law in effect at the time when, and governing the proceedings in
which, such damages are to be proved whether or not such amount be greater,
equal to, or less than any of the sums referred to in Section 18.01.

                                  ARTICLE 19

                LANDLORD'S RIGHT TO PERFORM TENANTS OBLIGATIONS

     19.01.  If Tenant shall default in the observance or performance of any
term or covenant on Tenant's part to be observed or performed under any of the
terms or provisions of this Lease, (a) Landlord may remedy such default for the
account of Tenant, immediately and without notice in case of emergency, or in
any other case if Tenant shall fail to remedy such default with all reasonable
dispatch after Landlord shall have notified Tenant in writing of such default
and the applicable grace period for curing such default shall have expired; and
(b) if Landlord makes any expenditures or incurs any obligations for the payment
of money in connection with such default including, but not limited to,
reasonable attorneys' fees in instituting, prosecuting or defending any action
or proceeding, such sums paid or obligations incurred, with interest at the
Interest Rate, shall be deemed to be additional rent hereunder and shall be paid
by Tenant to Landlord upon rendition of a bill to Tenant therefor. The
provisions of this Article 19 shall survive the expiration or other termination
of this Lease.

                                  ARTICLE 20

                                QUIET ENJOYMENT

     20.01. Landlord covenants and agrees that subject to the terms and
provisions of this Lease, if, and so long as, Tenant keeps and performs each and
every covenant, agreement, term, provision and condition herein contained on the
part or on behalf of Tenant to be kept or performed, then Tenant may quietly
enjoy the demised premises during the Term without hindrance by Landlord or any
person claiming through or under Landlord subject however, to (i) the
obligations of this Lease, and (ii) the provisions of Article 25 hereof with
respect to Superior Instruments which affect this Lease.

                                  ARTICLE 21

                            SERVICES AND EQUIPMENT

     21.01. So long as Tenant is not in default under any of the covenants of
this Lease beyond the expiration of any applicable grace period, Landlord shall:

            (a)  Provide necessary elevator facilities on business days from
8:00 a.m. to 6:00 p.m. and shall have at least one elevator subject to call at
all other times. At Landlord's option, the elevators shall be operated by
automatic control or by manual control, or by a combination of both of such
methods.

            (b)  Maintain in good repair the air conditioning, heating and
ventilating systems installed by Landlord as part of the base Building systems.
The base Building air conditioning, heating and ventilation systems will
function when seasonably required on business days from 8:00 a.m. to 6:00 p.m.
as more fully described in Schedule C annexed hereto and made a part hereof. The
air conditioning system (as it relates to the demised premises) shall have
separate controls in the demised premises and may be operated by Tenant as
required if the demised premises constitute an entire floor; with respect to
partial floors said controls shall be located in an area on Tenant's floor of
the Building accessible to Tenant. Landlord has informed Tenant that the windows
of the demised premises and the Building are sealed, and that the demised
premises may become uninhabitable and the air therein may become unbreathable
during the hours or days when Landlord is not required pursuant to this
paragraph to furnish heat or ventilation or when Tenant does not operate the
air-conditioning system. Any use or occupancy of the demised premises during
such hours shall be at the sole risk, responsibility and hazard of Tenant, and
Landlord shall have no responsibility or liability therefor. Such condition of
the demised premises shall not constitute nor be deemed to be a breach or a
violation of this Lease or of any provision thereof, nor shall it be deemed an
actual or constructive eviction nor shall Tenant claim or be entitled to claim
any abatement of rent nor make any claim for any damages or compensation by
reason of such condition of the demised premises. Tenant shall cause and keep
entirely unobstructed all the vents, intakes, outlets and

                                       44
<PAGE>

grilles, at all times and shall comply with and observe all regulations and
requirements prescribed by Landlord for the proper functioning of the heating,
ventilating and air-conditioning systems. Nothing contained herein shall be
deemed to require Landlord to furnish at Landlord's expense such electric energy
as is required to operate the air conditioning system serving the demised
premises. Subject to the provisions of Article 4 hereof all such electric energy
shall be furnished to Tenant at Tenant's cost and expense. In the event that
Tenant shall require heating, air conditioning or ventilation after hours,
Tenant shall pay Landlord's customary charges therefor as additional rent. All
tenants requesting after hours heating shall give Landlord reasonable advance
notice of such requirement. All tenants who require after hours air-conditioning
or ventilating shall have the responsibility of operating the air-conditioning
and ventilation systems by use of a separate key which Landlord shall provide.

            (c)  Provide the cleaning and janitorial services described on
Schedule F annexed hereto on business days.

            (d)  Furnish water for lavatory and drinking and office cleaning
purposes. If Tenant requires, uses or consumes water for any other purposes,
Tenant agrees that Landlord may install a meter or meters or other means to
measure Tenant's water consumption, and Tenant further agrees to reimburse
Landlord for the cost of the meter or meters and the installation thereof, and
to pay for the maintenance of said meter equipment and/or to pay Landlord's cost
of other means of measuring such water consumption by Tenant. Tenant shall
reimburse Landlord for the cost of all water consumed, as measured by said meter
or meters or as otherwise measured, including sewer rents.

            (e)  Landlord will at Tenant's request supply condenser water to any
supplementary air conditioning units installed by Tenant in the demised premises
in accordance with the provisions of this Lease and Tenant agrees to pay
Landlord its customary charges for so providing such condenser water to the
demised premises. In the event Tenant installs supplementary air conditioning
units serving the demised premises, Tenant covenants and agrees, at its sole
cost and expense, to maintain in full force and effect for so long as such air
conditioning unit remains in the Building, a maintenance agreement for the
periodic maintenance of such unit on customary terms with a contractor
reasonably acceptable to Landlord and to furnish a copy of said contract and all
extensions thereof to Landlord within five (5) days after demand.

     21.02. Landlord reserves the right without any liability whatsoever, or
abatement of fixed annual rent, or additional rent, to stop the heating, air
conditioning, elevator, plumbing, electric and other systems when necessary by
reason of accident or emergency or for repairs, alterations, replacements or
improvements, provided that except in case of emergency, Landlord will notify
Tenant in advance, if possible, of any such stoppage and, if ascertainable, its
estimated duration, and will proceed diligently with the work necessary to
resume such service as promptly as possible and in a manner so as to minimize
interference with the Tenant's use and enjoyment of the demised premises, but
Landlord shall not be obligated to employ overtime or premium labor therefor.

                                       45
<PAGE>

     21.03. Tenant shall reimburse Landlord for the cost to Landlord of removal
from the demised premises and the Building of so much of any refuse and rubbish
of Tenant as shall exceed that ordinarily accumulated daily in the routine of
general business office occupancy.

     21.04. Tenant agrees to employ such office maintenance contractor as
Landlord may from time to time designate, for all waxing, polishing, lamp
replacement, cleaning (other than those cleaning services Landlord is obligated
to furnish) and maintenance work in the demised premises, provided that the
quality thereof and the charges therefor are reasonably comparable to that of
other contractors. Tenant shall not employ any other contractor without
Landlord's prior written consent.

     21.05. Landlord will not be required to furnish any other services, except
as otherwise provided in this Lease.

                                  ARTICLE 22

owner of a lease of the Building or of the Land and Building), so that in the
event of any transfer of title to said Land and Building or said lease, or in
the event of a lease of the Building, or of the Land and Building, upon
notification to Tenant of such transfer or lease the said transferor landlord
shall be and hereby is entirely freed and relieved of all future covenants,
obligations and liabilities of Landlord hereunder, and it shall be deemed and
construed as a covenant running with the land without further agreement between
the parties or their successors in interest, or between the parties and the
transferee of title to said Land and Building or said lease, or the said lessee
of the Building or of the Land and Building, that the transferee or the lessee,
as applicable, has assumed and agreed to carry out any and all such covenants,
obligations and liabilities of Landlord hereunder.

     22.02. The term "Business Days" or "business days" as used in this Lease

     22.03. "Interest Rate" shall mean a rate per annum equal to the lesser of
(a) 2% above the so-called "prime rate" of Republic National Bank, as publicly
announced from time to time or if Republic National Bank shall cease to exist or
cease to announce such rate, any similar rate designated by Landlord which is
publicly announced from time to time by any other bank in the City of New York
having combined capital and surplus in excess of $100,000,000 or (b) the maximum
rate of interest, if any, which Tenant may legally contract to pay.

and other subdivisions thereof, or of any official thereof, or of any other
governmental, public or quasi-public authority, whether now or hereafter in

                          INVALIDITY OF ANY PROVISION

     23.01. If any term, covenant, condition or provision of this Lease or the
application thereof to any circumstance or to any person, firm or corporation
shall be invalid or unenforceable to any extent, the remaining terms, covenants,
conditions and provisions of this Lease shall not be affected thereby and each
remaining term, covenant, condition and provision of this Lease shall be valid
and shall be enforceable to the fullest extent permitted by law.

                                  ARTICLE 24

                                   BROKERAGE

     24.01. Tenant covenants, represents and warrants that Tenant has had no
dealings or negotiations with any broker or agent other than Insignia/Edward S.
Gordon Company, Inc. (which is representing Landlord) and Newmark & Company Real
Estate, Inc. (which is representing Tenant), in connection with the consummation
of this Lease, and Tenant covenants and agrees to pay, hold harmless and
indemnify Landlord from and against any and all cost, expense (including
reasonable attorneys' fees and court costs), loss and liability for any
compensation, commissions or charges claimed by any broker or agent, other than
the brokers specifically set forth in this Section 24.01, with respect to this
Lease or the negotiation thereof.

                                  ARTICLE 25

                                 SUBORDINATION

     25.01. This Lease is and shall be subject and subordinate to all ground or
underlying leases which may now or hereafter affect the Land or the Building and
to all

                                      47
<PAGE>

mortgages which may now or hereafter affect such leases, the Land or the
Building, and to all renewals, refinancings, modifications, replacements and
extensions thereof (hereinafter called "Superior Instruments"). The provisions
of this Section 25.01 shall be self-operative and no further instrument of
subordination shall be required. In confirmation of such subordination, Tenant
shall promptly execute and deliver at its own cost and expense any instrument,
in recordable form if required, that Landlord, the holder of any Superior
Instrument or any of their respective successors in interest may request to
evidence such subordination, and Tenant hereby constitutes and appoints Landlord
or its successors in interest to be Tenant's attorney-in-fact, irrevocably and
coupled with an interest, to execute and deliver any such instrument for and on
behalf of Tenant.

     25.02. In the event of a termination of any ground or underlying lease, or
if the interests of Landlord under this Lease are transferred by reason of, or
assigned in lieu of, foreclosure or other proceedings for enforcement of any
mortgage, or if the holder of any mortgage acquires a lease in substitution
therefor, then Tenant under this Lease will, at the option to be exercised in
writing by the holder of any such Superior Instrument or any purchaser, assignee
or lessee, as the case may be, either (i) attorn to it and will perform for its
benefit all the terms, covenants and conditions of this Lease on Tenant's part
to be performed with the same force and effect as if it were the landlord
originally named in this Lease, or (ii) enter into a new lease with it for the
remaining term of this Lease and otherwise on the same terms and conditions and
with the same options, if any, then remaining. The foregoing provisions of
clause (i) of this Section 25.02 shall enure to the benefit of such holder of a
Superior Instrument, purchaser, assignee or lessee, shall be self-operative upon
the exercise of such option, and no further instrument shall be required to give
effect to such option, and no further instrument shall be required to give
effect to said provisions. Tenant, however, upon demand of any such holder of a
Superior Instrument, purchaser, assignee or lessee agrees to execute, from time
to time, instruments in confirmation of the foregoing provisions of this Section
25.02, satisfactory to any such holder of a Superior Instrument, purchaser,
assignee or lessee, acknowledging such attornment and setting forth the terms
and conditions of its tenancy. Tenant hereby constitutes and appoints Landlord
or its successors in interest to be the Tenant's attorney-in-fact, irrevocably
and coupled with an interest, to execute and deliver such instrument of
attornment, or such new lease, if the Tenant refuses or fails to do so promptly
upon request.

     25.03. Anything herein contained to the contrary notwithstanding, under no
circumstances shall any such holder of a Superior Instrument, purchaser,
assignee or lessee, as the case may be, whether or not it shall have succeeded
to the interests of the landlord under this Lease, be

            (a)  liable for any act, omission or default of any prior landlord;
or

            (b)  subject to any offsets, claims or defenses which the Tenant
might have against any prior landlord; or

                                      48
<PAGE>

          (c)  bound by any rent or additional rent which Tenant might have paid
to any prior landlord for more than one month in advance or for more than three
months in advance where such rent payments are payable at intervals of more than
one month; or

          (d)  bound by any modification, amendment or abridgment of the Lease,
or any cancellation or surrender of the same, made without its prior written
approval;

          (e)  obligated to do or complete any work in the demised premises
pursuant to Article 2 hereof or otherwise be obligated to prepare the demised
premises for occupancy in accordance with the provisions of this Lease.

     25.04. If, in connection with the financing of the Building, the holder of
any mortgage shall request reasonable modifications in this Lease as a condition
of approval thereof, Tenant will not unreasonably withhold, delay or defer
making such modifications provided the same do not (i) increase the fixed annual
rent or additional rents payable by Tenant, (ii) reduce the term hereof or (iii)
extend the term hereof.

                             CERTIFICATE OF TENANT

     26.01. Tenant shall, without charge, at any time and from time to time,
within ten (10) days after request by Landlord or the holder of a Superior
Instrument, as the case may be, execute, acknowledge and deliver to Landlord,
the holder of a Superior Instrument or any other person, firm or corporation
specified by Landlord, a written instrument (an "Estoppel Certificate") in the
form attached hereto as Schedule D or such other form as may be required by the
holder of any Superior Instrument. Prior to taking occupancy of the demised
premises, and as a condition precedent thereto, Tenant shall execute,
acknowledge and deliver such an estoppel certificate to Landlord

     26.02. Tenant agrees that, except for the first month's rent hereunder, it
will pay no rent under this Lease more than thirty (30) days in advance of its
due date, if so restricted by any existing or future Superior Instrument or by
an assignment of this Lease to the holder of such Superior Instrument, and, in
the event of any act or omission by Landlord which would give Tenant the right
to terminate this Lease, Tenant will not exercise such right until Tenant shall
have first given written notice of such act or omission to the holder of any
Superior Instrument who shall have furnished such holder's last address to
Tenant, and until a reasonable period for remedying such act or omission shall
have elapsed following the giving of such notices (which reasonable period shall
in no event be less than the period to which Landlord would be entitled under
this Lease or otherwise, after similar notice, to effect such remedy), during
which time such holder shall have the right, but shall not be obligated, to
remedy or cause to be remedied such act or omission. Tenant further agrees not
to exercise any such right if the holder of any

                                      49
<PAGE>

such Superior Instrument commences to cure such act or omission within a
reasonable time after having received notice thereof and diligently prosecutes
such cure thereafter.

                                  ARTICLE 27

                    LEGAL PROCEEDINGS, WAIVER OF JURY TRIAL

     27.01. Landlord and Tenant hereby waive trial by jury in any action,
proceeding or counterclaim brought by either of the parties hereto against the
other on any matters whatsoever arising out of or in any way in connection with
this Lease, the relationship of Landlord and Tenant, Tenant's use or occupancy
of the demised premises, and/or any other claims (except claims for personal
injury or property damage), and any emergency statutory or any other statutory
remedy. It is further mutually agreed that in the event Landlord commences any
summary proceeding for non-payment of rent, Tenant will not interpose and does
hereby waive the right to interpose any counterclaim of whatever nature or
description in any such proceeding except mandatory counter claims. Tenant shall
reimburse Landlord upon demand for all costs and expenses (including attorneys'
fees and disbursements and court costs) incurred by Landlord in connection with
enforcing Tenant's obligations hereunder or in protecting Landlord's rights
hereunder whether incurred in connection with an action or proceeding commenced
by Landlord, by Tenant, by a third party or otherwise. All such amounts shall be
deemed to be additional rent and shall be collectible in the same manner as
provided in Section 1.02 hereof.

                                  ARTICLE 28

                             SURRENDER OF PREMISES

     28.01. Upon the expiration or other termination of the Term, Tenant shall
quit and surrender to Landlord the demised premises, broom clean, in good order
and condition, ordinary wear and tear and damage by fire, the elements or other
casualty excepted, and Tenant shall remove all of its property as herein
provided. Tenant's obligation to observe or perform this covenant shall survive
the expiration or other termination of the Term.

     28.02. If Tenant shall, without the written consent of Landlord, hold over
after the expiration of the Term, and if Landlord shall then not proceed to
remove Tenant from the demised premises in the manner permitted by law, such
tenancy shall be deemed a month-to-month tenancy, which tenancy may be
terminated as provided by applicable law. During such tenancy, Tenant agrees to
(a) pay to Landlord, each month, the greater of the fair market rental value for
the demised premises or the sum of (i) one hundred fifty (150%) percent of the
fixed annual rent and (ii) one hundred (100%) percent of the additional rent
payable by Tenant for the last month of the Term and (b) be bound by all of the
terms, covenants and conditions herein specified.

                             RULES AND REGULATIONS

     29.01. Tenant and Tenant's servants, employees and agents shall observe
faithfully and comply strictly with the Rules and Regulations set forth in
Schedule E attached hereto and made part hereof entitled "Rules and Regulations"
and such other and further reasonable Rules and Regulations as Landlord or
Landlord's agents may from time to time adopt provided, however, that in case of
any conflict or inconsistency between the provisions of this Lease and of any of
the Rules and Regulations as originally or as hereafter adopted, the provisions
of this Lease shall control. Reasonable written notice of any additional Rules
and Regulations shall be given to Tenant.

     Nothing in this Lease contained shall be construed to impose upon Landlord
any duty or obligation to enforce the Rules and Regulations or the terms,
covenants or conditions in any other lease, against any other tenant of the
Building, and Landlord shall not be liable to Tenant for violation of the same
by any other tenant, its servants, employees, agents, visitors or licensees.

                                  ARTICLE 30

                            CONSENTS AND APPROVALS

     30.01. Wherever in this Lease Landlord's consent or approval is required,
if Landlord shall delay or refuse such consent or approval, Tenant in no event
shall be entitled to make, nor shall Tenant make, any claim, and Tenant hereby
waives any claim, for money damages (nor shall Tenant claim any money damages by
way of set-off, counterclaim or defense) based upon any claim or assertion by
Tenant that Landlord unreasonably withheld or unreasonably delayed its consent
or approval. Tenant's sole remedy shall be an action or proceeding to enforce
any such provision, for specific performance, injunction or declaratory
judgment, and such remedy shall be available only in those cases where Landlord
has expressly agreed in writing not to unreasonably withhold its consent or
where as a matter of law Landlord may not unreasonably withhold its consent.

                                  ARTICLE 31

                                    NOTICES

     31.01. Any notice or demand, consent, approval or disapproval, or
statement (collectively called "Notices") required or permitted to be given by
the terms and provisions of this Lease, or by any law or governmental
regulation, either by Landlord to Tenant or by Tenant to Landlord, shall be in
writing and unless otherwise required by such law or regulation, shall be

                                      51
<PAGE>

sent by either (i) United States mail postage prepaid as registered or certified
mail, return receipt requested, or (ii) nationally recognized overnight courier
(e.g., Federal Express). Any Notice shall be addressed to Landlord or Tenant, as
applicable, at its address set forth on page 1 of this Lease as said address may
be changed from time to time as hereinafter provided. After Tenant shall occupy
the demised premises, the address of Tenant for Notices shall be the Building.
By giving the other party at least ten days prior written notice, either party
may, by Notice given as above provided, designate a different address or
addresses for Notices.

     31.02. Any Notice shall be deemed given (i) three (3) business days after
being deposited in the U.S. mail, as hereinbefore set forth, or (ii) one (1)
business day after being sent by nationally recognized overnight courier.

     31.03. In addition to the foregoing, either Landlord or Tenant may, from

                                   NO WAIVER

     32.01. No agreement to accept a surrender of this Lease shall be valid
unless in writing signed by Landlord. No employee of Landlord or of Landlord's
agents shall have any power to accept the keys of the demised premises prior to
the termination of this Lease. The delivery of keys to any employee of Landlord
or of Landlord's agent shall not operate as a termination of this Lease or a
surrender of the demised premises. In the event of Tenant at any time desiring
to have Landlord sublet the premises for Tenant's account, Landlord or
Landlord's agents are authorized to receive said keys for such purpose without
releasing Tenant from any of the obligations under this Lease. The failure of
Landlord to seek redress for violation of, or to insist upon the strict
performance of, any covenant or condition of this Lease or any of the Rules and
Regulations set forth herein, or hereafter adopted by Landlord, shall not
prevent a subsequent act, which would have originally constituted a violation,
from having all the force and effect of an original violation. The receipt by
Landlord of rent with knowledge of the breach of any covenant of this Lease
shall not be deemed a waiver of such breach. The failure of Landlord to enforce
any of the Rules and Regulations set forth herein, or hereafter adopted, against
Tenant and/or any other tenant in the Building shall not be deemed a waiver of
any such Rules and Regulations. No provision of this Lease shall be deemed to
have been waived by Landlord, unless such waiver be in writing signed by
Landlord. No payment by Tenant or receipt by Landlord of a lesser amount than
the monthly rent herein stipulated shall be deemed to be other than on the
account of the earliest stipulated rent, nor shall any endorsement or statement
on any check or any letter accompanying any check or payment of rent be deemed
an accord and satisfaction, and Landlord may accept such check or payment
without prejudice to Landlord's right to recover the balance of such rent or
pursue any other remedy in this Lease provided.

enforcement of the change, modification, discharge or abandonment is sought.

and counterpart copies thereof shall be delivered to each of the parties. In
rendering such decision and awards, the arbitrators shall not add to, subtract
from or otherwise modify the provisions of this Lease. Judgment may be had on
the decision and award of the arbitrators so rendered in any court of competent
jurisdiction.

                                   INDEMNITY

     38.01 Subject to the terms of Article 9 hereof relating to waivers of
subrogation Tenant shall indemnify and defend Landlord (including Landlord's

including attorneys' fees, arising from (i) any act, omission, or negligence of
Tenant or its officers, contractors, licensees, agents, employees, guests,

officers, contractors, licensees, agents, employees, or invitees, and nothing

                             APPROVAL OF MORTGAGEE

this Lease by the holder of the first mortgage on the Land and Building.

                                  ARTICLE 40

                               SECURITY DEPOSIT

     40.01. Tenant has deposited with Landlord the sum of $55,680.00 as security
for the full and punctual performance by Tenant of all of the terms of this
Lease. Landlord shall hold such security deposit in an interest-bearing account,
to be selected by Landlord, and the interest earned thereon (less an
administrative fee of one (1%) percent per annum of the principal) shall be
returned to Tenant upon Tenant's written request but not more frequently than
annually. In the event Tenant defaults in the performance of any of the terms of
this Lease, Landlord may apply the whole or any part of the security so
deposited to the extent required for the payment of (i) any rent or (ii) any sum
which Landlord may expend or may be required to expend by reason of Tenant's
default including, without limitation, any damages or deficiency in the re-
letting of the demised premises, whether accruing before or after summary
proceedings or other re-entry by Landlord. Upon each such application, Tenant
shall, on demand, pay to Landlord the sum so applied which shall be added to the
security deposit so that the same shall be restored to the amount first set
forth above. The amount of the security deposit, with interest, shall be
returned to Tenant after the termination of this Lease and delivery of exclusive
possession of the demised premises to Landlord. In the event of a sale or lease
of the Building, Landlord shall have the right to transfer the security to the
vendee or lessee and Landlord shall ipso facto be released by Tenant from all
liability for the return of such security; and Tenant agrees to look solely to
the new landlord for the return of said security and it is agreed that the
provisions hereof shall apply to every transfer or assignment made of the
security to a new landlord. Tenant shall not assign or encumber or attempt to
assign or encumber the monies deposited herein as security and neither Landlord
nor its successors or assigns shall be bound by any such assignment,
encumbrance, or attempted assignment or encumbrance.

     40.02. In lieu of the cash security deposit provided for in Section 40.01
hereof, Tenant may at any time during the term hereof deliver to Landlord and
shall thereafter, except as otherwise provided herein, maintain in effect at all
times during the term hereof, an irrevocable letter of credit, in form and
substance reasonably satisfactory to Landlord in the amount of the security
required pursuant to this Article 40 issued by a banking corporation
satisfactory to Landlord and having its principal place of business or its duly
licensed branch or agency in the State of New York. Such letter of credit shall
have an expiration date no earlier than the first anniversary of the date of
issuance thereof and shall be automatically renewed from year to year unless
terminated by the issuer thereof by notice to Landlord given not less than
forty-five (45) days prior to the expiration thereof. Except as otherwise
provided in this Article 40, Tenant shall,

                                      55
<PAGE>

throughout the term of this lease deliver to Landlord, in the event of the
termination of any such letter of credit, replacement letters of credit in lieu
thereof (each such letter of credit and such extensions or replacements thereof,
as the case may be, is hereinafter referred to as a "Security Letter") no later
than forty-five (45) days prior to the expiration date of the preceding Security
Letter. The term of each such Security Letter shall be not less than one (1)
year and shall be automatically renewable from year to year as aforesaid. If
Tenant shall fail to obtain any replacements of a Security Letter within the
time limits set forth in this Section 40.02, Landlord may draw down the full
amount of the existing Security Letter and retain the same as security
hereunder.

     40.03. In the event Tenant defaults in respect of any of the terms,
provisions, covenants and conditions of this lease, beyond any applicable grace
period, including, but not limited to, the payment of fixed annual rent and
additional rent, Landlord may use, apply or retain the whole or any part of the
security so deposited to the extent required for the payment of any fixed annual
rent and additional rent or any other sum as to which Tenant is in default or
for any sum which Landlord may expend or may be required to expend by reason of
Tenant's default in respect of any of the terms, provisions, covenants, and
conditions of this lease, including but not limited to, any damages or
deficiency accrued before or after summary proceedings or other re-entry by
Landlord. To insure that Landlord may utilize the security represented by the
Security Letter in the manner, for the purposes, and to the extent provided in
this Article 40, each Security Letter shall provide that the full amount thereof
may be drawn down by Landlord upon the presentation to the issuing bank of
Landlord's sight draft drawn on the issuing bank.

     40.04. In the event that Tenant defaults in respect of any of the terms,
provisions, covenants and conditions of the lease and Landlord utilizes all or
any part of the security represented by the Security Letter but does not
terminate this Lease as provided in Article 16 hereof, Landlord may, in addition
to exercising its rights as provided in Section 40.03 hereof, retain the
unapplied and unused balance of the principal amount of the Security Letter as
security for the faithful performance and observance by Tenant thereafter of the
terms, provisions, and conditions of this lease, and may use, apply, or retain
the whole or any part of said balance to the extent required for payment of
fixed annual rent, additional rent, or any other sums as to which Tenant is in
default or for any sum which Landlord may expend or be required to expend by
reason of Tenant's default in respect of any of the terms, covenants, and
conditions of this lease. In the event Landlord applies or retains any portion
or all of the security delivered hereunder, Tenant shall forthwith restore the
amount so applied or retained so that at all times the amount deposited shall be
not less than the security required by this Article 40.

     40.05. The security or any balance thereof to which Tenant is entitled
shall be returned or paid over to Tenant reasonably promptly after the date
fixed as the end of this lease and after delivery to Landlord of entire
possession of the Premises. In the event of any sale, transfer or leasing of
Landlord's interest in the Building whether or not in connection with a sale,
transfer or leasing of the Land to a vendee, transferee or lessee, Landlord
shall transfer the unapplied part of the security and the interest thereof, if
any, to which Tenant is entitled, or any interest it may have in the Security
Letter, as the case may be, to the vendee, transferee or lessee

                                       56
<PAGE>

and Landlord shall thereupon be released by Tenant from all liability for the
return or payment thereof, and Tenant shall look solely to the new Landlord for
the return or payment of the same. The provisions of the preceding sentence
shall apply to every subsequent sale, transfer or leasing of the Building, and
any successor of Landlord shall, upon a sale, transfer, leasing or other
cessation of the interest of such successors in the Building whether in whole or
in part, pay over any unapplied part of said security or any interest it may
have in the Security Letter, as the case may be, to any vendee, transferee or
lessee of the Building, and shall thereupon be relieved of any liability with
respect thereto. In the event of a sale of the Building, Landlord shall have the
right to require Tenant to deliver a replacement Security Letter naming the new
Landlord as beneficiary and, if Tenant shall fail to timely deliver the same, to
draw down the existing Security Letter and retain the proceeds as security
hereunder until a replacement Security Letter is delivered. Except in connection
with a permitted assignment of this lease, Tenant shall not assign or encumber
or attempt to assign or encumber the monies deposited herein as security or any
interest thereon to which Tenant is entitled, and neither Landlord nor its
successors or assigns shall be bound by any such assignment, encumbrance,
attempted assignment or attempted encumbrance. In any event, in the absence of
evidence satisfactory to Landlord of an assignment of the right to receive the
security, or the remaining balance thereof, Landlord may return the security to
the original Tenant regardless of one or more assignments of this lease.

     40.06. Provided and on condition that Tenant shall not then be in default
under any of the terms and conditions of this Lease after notice and the
expiration of any applicable grace period, and further provided that Tenant
shall not, more than once within any 12-month period during the Term hereof,
have paid any payments of fixed annual rent or additional rent more than seven
(7) days after their due date, then in such event, the amount of the security
requirement set forth in Section 40.01 shall be reduced as follows: (x) to
$37,120 as of the first (1st) anniversary of the Rent Commencement Date, and (y)
to $18,560 as of the second (2nd) anniversary of the Rent Commencement Date. If
the security shall be in the form of a Security Letter, then such Security
Letter then in effect may be replaced by Tenant with a Security Letter in the
amount of $37,120 as of the first (1st) anniversary of the Rent Commencement
Date, and $18,560.00 as of the second (2nd) anniversary of the Rent Commencement
Date, in the same form and manner as described heretofore in this Article 40.

                                  ARTICLE 41

                                 MISCELLANEOUS

other rule requiring construction against the party causing this Lease to be

     41.03.  Except as otherwise expressly provided in this Lease, each

gender in which they are used, shall be deemed to include any other number and

     41.07.  If the demised premises or any additional space to be included
within the demised premises shall not be available for occupancy by Tenant on
the date hereinbefore designated for the commencement of the term of this Lease
or for the inclusion of such space for any reason whatsoever, then this Lease
shall not be affected thereby but, in such case, said specific date shall be
deemed to be postponed until the date when the demised premises or such
additional space shall be available for occupancy by Tenant, and Tenant shall
not be entitled to possession of the demised premises or such additional space
until the same are available for occupancy by Tenant; provided, however, Tenant
shall have no claim against Landlord, and Landlord shall have no liability to
Tenant by reason of any such postponement of said specific date, and the parties
hereto further agree that any failure to have the demised premises or such
additional space available for occupancy by Tenant on said specific date or on
the Commencement Date shall in no way affect the obligations of Tenant hereunder
nor shall the same be construed in any way to extend the Term. This Section
41.07 shall be deemed to be an express provision to the contrary of Section 223-
a of the Real Property Law of the State of New York and any other law of like
import now or hereafter in force.

     41.08.  In the event that Tenant is in arrears in payment of fixed annual
rent or additional rent hereunder, Tenant waives Tenant's right, if any, to
designate the items against which any payments made by Tenant are to be
credited, and Tenant agrees that Landlord may apply any payments made by Tenant
to any items it sees fit, irrespective of and notwithstanding any designation or
request by Tenant as to the items against which any such payments shall be
credited.

     41.09.  All Schedules referred to in this Lease are hereby incorporated in
this Lease by reference.

     41.10.  The covenants, conditions and agreements contained in this Lease
shall bind and inure to the benefit of Landlord and Tenant and their respective
heirs, distributees, executors, administrators, successors, and except as
otherwise provided in this Lease, their assigns.

Landlord in any way whatsoever until (i) Tenant has duly executed and delivered
duplicate originals to Landlord, and (ii) Landlord has executed and delivered

pursuant to the terms and conditions of this Agreement. Subject to the terms and
conditions of this Agreement, amounts borrowed pursuant to Section 1(a) may be
repaid and reborrowed at any time during the term of this Agreement.

Maturity or until prepaid in accordance with this Agreement at a floating rate
equal to the Prime Rate, as published in the Western Edition of The Wall Street

shall bear interest at a rate equal to the greater of 18% or 5% above the rate

extension, late fees and default interest shall not be construed as Sand Hill's

claim and is given sole control of the defense of such claim and of all related
settlement negotiations relating thereto. At its option, 2Bridge may terminate
this Agreement upon written notice to Subscriber and release the Subscriber of

title, copyright and other proprietary rights in and to the Software and that
Subscriber will obtain only such rights to use the Software as are expressly
provided herein.

3.  Administration of License.

       3.1  License Administrator.  Subscriber will appoint and identify to
            ---------------------
2Bridge an individual who will administer Subscriber's obligations hereunder and
respond to all inquiries by 2Bridge in connection with Subscriber's performance
hereunder ("License Administrator"). The License Administrator shall be
responsible for maintaining a current and updated list of all User names and
locations, as well as all installed server copies of the Software, and shall
provide a copy of that list to 2Bridge upon request.

       3.2  Scope of "Authorized User".  Copies of the Software may only be used
            --------------------------
by Subscriber and its branches, subsidiaries, and companies under common control
in existence as of the date of this Agreement. Upon request by Subscriber and
written approval by 2Bridge, Subscriber may add or remove branches,
subsidiaries, or companies under common control to the list of Authorized User
entities. 2Bridge may cause to be excluded from the scope of such user entities
any entity or location for which 2Bridge reasonably determines that Subscriber
has failed to adequately administer the terms of this Agreement.

       3.3  Audit and Inspection Rights.  In order to enable 2Bridge to confirm
            ---------------------------
the accuracy of information and protect its intellectual property rights
hereunder, Subscriber agrees: (i) to run the standard usage reports generated by
the Software, the 2Share Server Reports, upon 2Bridge's request; and (ii) to
allow 2Bridge's certified public accountants to audit and analyze the records of
Software use and location or other records of Subscriber to confirm the number
of copies of the Software used and installed at any Authorized User entity's
location. Any such audit shall be permitted by such user entity upon receipt of
reasonable notice, during normal business hours, at a time mutually agreed by
2Bridge and such user entity. The cost of such an audit will be borne by
2Bridge. Audits shall be made no more frequently than semi-annually and will not

                                      -2-
<PAGE>

interfere unreasonably with the Authorized User entity's business activities.

4.  Subscriber Support.

       4.1  Subscriber Support.  Subscriber shall be entitled to support
            ------------------
services ("Support Services"). Such Support Services include efforts to: (i)
answer Subscriber's questions communicated to 2Bridge through a designated
Subscriber technical liaison regarding the proper utilization of the Software,
(ii) identify defective source code, (iii) update the Software with versions to
correct any material program errors or to provide minor functional enhancements
that are made available by 2Bridge to subscribers at no additional charge
("Updates").

       4.2  Support Policies.  2Bridge shall have no obligation to provide
            ----------------
Support Services until it has received the monthly fees due for the then-
existing Term. Subscriber acknowledges that all reported errors may not be
corrected, and 2Bridge shall have no obligation to correct any errors which
2Bridge is unable to reproduce or which are caused by: (i) Subscriber's hardware
or network equipment, (ii) use of the Software for other than the specific
purpose for which the Software is designed, (iii) accident, transportation,
neglect, misuse, modification or enhancement of the Software, or (iv) any
alterations of or additions to the Software performed by parties other than
2Bridge. All restrictions and limitations relating to the Software apply to
Updates. 2Bridge reserves the right to impose additional fees for any releases
which 2Bridge designates as new products.

5.  Warranty and Indemnity.

       5.1  Limited Warranty.  2Bridge warrants for Subscriber's sole benefit
            ----------------
for a period of 90 days from the date of delivery of the Software to Subscriber
(the "Warranty Period"): (a) that the media on which the Software was delivered,
if provided by 2Bridge, will be free from defects in material and workmanship;
(b) that the Software will function substantially in accordance with the
specifications in the applicable Documentation in effect when the Software is
delivered; (c) that the Software Documentation shall be accurate in all material
respects; and (d) the Software shall be free of any willfully introduced
computer virus or any other similarly harmful, malicious or hidden program or
data including without limitation, any hardware or software device or code which
shall prevent any Authorized User from accessing or using the Software or any
portion thereof.

       5.2  Limited Remedy.  In the event of a material breach of the foregoing
            --------------
warranty, 2Bridge shall use reasonable commercial efforts pursuant to its
provision of Support Services to promptly provide an Update to the 2Bridge
Software to render it compliant with the foregoing warranty, or refund the
monthly fee allocable to the non-conforming Software for the month(s) in which
such Software was non-conforming following notification by Subscriber. THE
FOREGOING CONSTITUTES SUBSCRIBER'S SOLE AND EXCLUSIVE REMEDY FOR BREACH BY
2BRIDGE OF WARRANTY UNDER THIS AGREEMENT.

       5.3  Infringement Indemnity. 2Bridge shall defend Subscriber against any
            ----------------------
third-party claim based upon an allegation that the Software infringes a United
States copyright, trademark, or trade secret, but only if 2Bridge is notified
promptly in writing of such claim and is given sole control of the defense of
such claim and of all related settlement negotiations relating thereto. At its
option, 2Bridge may terminate this Agreement upon written notice to Subscriber
and release the Subscriber of its remaining contract obligations.
NOTWITHSTANDING THE FOREGOING, 2BRIDGE SHALL NOT BE LIABLE FOR ANY CLAIM ARISING
FROM OR BASED UPON ANY ALTERATION OR MODIFICATION OF THE SOFTWARE. THE FOREGOING
STATES 2BRIDGE'S ENTIRE LIABILITY AND SUBSCRIBER'S SOLE REMEDY IN CONNECTION
WITH ANY INTELLECTUAL PROPERTY INFRINGEMENT CLAIMS ARISING OUT OF OR RELATED TO
THE 2BRIDGE SERVICE.

       5.4  Disclaimer. EXCEPT AS EXPRESSLY SET FORTH ABOVE, 2BRIDGE EXPRESSLY
            ----------
DISCLAIMS ALL OTHER WARRANTIES AND CONDITIONS, EXPRESS, IMPLIED, OR STATUTORY,
INCLUDING THE IMPLIED WARRANTIES OR CONDITIONS OF MERCHANTABILITY, FITNESS FOR A
PARTICULAR PURPOSE, SATISFACTORY QUALITY, AND NONINFRINGEMENT, AND THEIR
EQUIVALENTS UNDER THE LAWS OF ANY JURISDICTION. IF APPLICABLE LAW IMPLIES ANY
WARRANTIES OR CONDITIONS WITH RESPECT TO THE SOFTWARE, ALL SUCH WARRANTIES OR
CONDITIONS ARE LIMITED IN DURATION TO THIRTY (30) DAYS FROM THE DATE OF USER'S
FIRST INSTALLATION OF THE SOFTWARE.  WITHOUT LIMITING THE FOREGOING, 2BRIDGE
DOES NOT WARRANT THAT THE FUNCTIONS CONTAINED IN THE SOFTWARE WILL MEET
SUBSCRIBER'S

                                      -3-
<PAGE>

REQUIREMENTS, OR THAT THE OPERATION OF THE SOFTWARE WILL BE UNINTERRUPTED OR
ERROR-FREE, OR THAT DEFECTS IN THE SOFTWARE WILL BE CORRECTED.

6.  Limitation of Liability. UNDER NO CIRCUMSTANCES AND UNDER NO LEGAL THEORY,
TORT (INCLUDING NEGLIGENCE), CONTRACT, OR OTHERWISE, SHALL 2BRIDGE BE LIABLE FOR
ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY CHARACTER,
INCLUDING WITHOUT LIMITATION, DAMAGES FOR LOST PROFITS OR LOST DATA, BUSINESS
INTERRUPTION, COMPUTER FAILURE OR MALFUNCTION, OR ANY AND ALL OTHER COMMERCIAL
DAMAGES OR LOSSES OCCASIONED BY THE USE OF THE SOFTWARE.  NOTWITHSTANDING
ANYTHING TO THE CONTRARY HEREIN, IN NO EVENT WILL 2BRIDGE'S AGGREGATE LIABILITY
ARISING OUT OF OR RELATING TO THIS AGREEMENT EXCEED THE TOTAL PAYMENTS MADE BY
SUBSCRIBER HEREUNDER, EVEN IF 2BRIDGE SHALL HAVE BEEN ADVISED OF THE POSSIBILITY
OF SUCH DAMAGES.

7.  Fees and Payment Terms.

       7.1  Invoicing and Payment.  Invoices for payment of all subscription and
            ---------------------
other fees shall be payable as detailed on Schedule A or the applicable 2Bridge
Order Form. All fees shall be deemed overdue if they remain unpaid 30 days after
they become payable. All subscription fees and other fees payable hereunder are
non-refundable. All overdue amounts shall bear interest at the rate of one and
one-half percent (1-1/2%) per month or the maximum legal rate, if less, however,
nothing herein shall limit 2Bridge's right to terminate this Agreement under
Section 8.2 below. Subscriber shall reimburse 2Bridge for all reasonable costs
incurred (including reasonable attorneys' fees) in collecting past due amounts.

       7.2  Taxes. The fees listed in this Agreement do not include taxes.  The
            -----
Subscriber shall pay or reimburse 2Bridge for all sales, use, excise, personal
property, value-added, or other federal, state or local taxes, duties, or any
similar assessments based on the rights granted or the services provided under
this Agreement or on the Subscriber's use of the Software; however, the
Subscriber shall have no responsibility for 2Bridge's income or franchise taxes.

       7.3  Shipment. All shipments of Software shall be F.O.B. 2Bridge's
            --------
facility or an authorized reseller's facility and uninsured, unless Subscriber
requests in writing that 2Bridge obtains insurance on Subscriber's behalf and
agrees to pay the additional charge for such insurance. 2Bridge will use
reasonable efforts to ship on or before estimated shipping dates. Shipping dates
are approximate.

8.  Term and Termination.

       8.1  Term. The "Term" of this Agreement and the license granted hereunder
            ----
shall be one (1) year for an annual subscription or as described in Schedule A
or the applicable 2Bridge Order Form, and shall commence on the Effective Date.
Unless terminated as set forth in Section 8.2, the Term shall automatically
renew for one or more successive terms of one (1) year on a annual subscription
or for such periods as are described in Schedule A, each upon the expiration of
the then-current Term.

       8.2  Termination.  Either party may terminate this Agreement in the event
            -----------
of a material breach by the other party that is not cured within thirty (30)
days of the nonbreaching party giving written notice of the breach and its
intent to terminate if uncured; provided that the cure period for payment
obligations shall be ten (10) days. Additionally, Subscriber may terminate this
Agreement upon the expiration of the then-current Term, upon sixty (60) days
advance written notice to 2Bridge.

       8.3  Effect of Termination.  Upon termination, Subscriber must, within
            ---------------------
thirty (30) days of such termination, erase the Software, and all portions
thereof, from all computer memories and storage devices within Subscriber's
possession or control, and represent in writing to 2Bridge that it has done so.
Termination of this Agreement or any license shall not limit either party from
pursuing any other remedies available to it, including injunctive relief, nor
shall such termination relieve the Subscriber's obligation to pay all fees that
accrued prior to such termination. Sections 2.4, 3.3, 5.4, 6, 8.3, 9, and 10
shall survive any expiration or termination of this Agreement.

9.  Nondisclosure Obligations.

       9.1  Confidential Information.  By virtue of this Agreement, each party
            ------------------------
may have access to information that is confidential to the other party

<PAGE>

information related thereto, all information clearly marked as confidential, and
other terms as agreed by the parties in writing.

       9.2  Exceptions. A party's Confidential Information shall not include
            ----------
information which:  (i) is or becomes a part of the public domain through no act
or omission of the receiving party; or (ii) was in the other party's lawful
possession prior to the disclosure and had not been obtained by the receiving
party either directly or indirectly from the disclosing party; (iii) is lawfully
disclosed to the receiving party by a third party without restriction on

prior written consent which may be withheld in 2Bridge's sole discretion.

       9.3  Nondisclosure.  The parties agree, both during the term of this
            -------------
Agreement and for a period of five (5) years after termination hereof, to hold
each other's Confidential Information in confidence. The parties agree not to
make each other's Confidential Information available in any form to any third
party or to use each other's Confidential Information for any purpose other than
the implementation of this Agreement without the other party's prior written
consent. Each party agrees to take all reasonable steps to ensure that
Confidential Information is not disclosed or distributed by its employees or
agents in violation of the provisions of this Agreement.

10.  Miscellaneous.

       10.1  Export Controls.  User may not export or re-export the Software or

limitation, all United States Department of Commerce and export laws. Subscriber

benefit of 2Bridge's and Subscriber's successors and assigns. However, neither
this Agreement, nor any part of the Software may be assigned, sublicensed, sold,

of law or otherwise, without the prior written consent of 2Bridge. Any attempted
assignment in violation of this Section 10.3 shall be null and void.

             ----------------
of the parties on the subject matter and supersedes all prior agreements and

     The "Term" of this agreement shall be one (1) year, as described in
Schedule A, and shall commence on the Effective Date. Unless terminated as set

     All of the terms and conditions contained in the Subscription Agreement
referred to in this Order Form shall apply to the Software or Services ordered
hereunder.  All programs, documentation, reports, techniques, designs and other

set forth in this 2Bridge Order Form for Software and Services, as more fully
set forth in the attached description(s), do not include out-of-pocket expenses
(such as transportation, lodging, meal per diem, and other expenses) incurred by

reasons Subscriber shall pay 2Bridge's then prevailing daily charge, plus
reimbursement of all such out-of-pocket expenses, for each additional day for
each person assigned by 2Bridge to provide the Services.  Subscriber shall

has been deemed unacceptable.  Upon any such notice, 2Bridge shall modify its
performance of the Services so as to make them reasonably acceptable to
Subscriber.  The passage of the ten (10) days following completion of all or a
part of the Services without written notice of non-acceptance, or the use by
Subscriber of any Software employing of all or of a part of the Services in any
productive mode, shall constitute acceptance by Subscriber of such Services.

"confidential information" in any other agreement between Customer and 2Bridge,
whether executed prior to or after the date of this Agreement, or any

be obligated to perform any additional or different Services until it gives
Customer written acceptance of the Change Order.

       2.3.   Software. The Services will generally consist of enhancements or
              --------
customizations to a current release of the Software, in accordance with the
Specifications.  2Bridge will not be responsible for the migration or re-
implementation of the Services or the Application for future releases of the
Software unless Customer separately contracts for such migration or re-
implementation.

3.   Customer's Duties and Responsibilities
     --------------------------------------

       3.1. Data and Information. Customer shall make available in a timely
            --------------------
manner at no charge to 2Bridge all computer facilities, data, programs, files,
documentation, artwork, graphics, or other information and resources required by
2Bridge for the performance of the Services. Customer will be responsible for,
and assumes the risk of any problems resulting from, the content, accuracy,
completeness and consistency of all such data, materials and information
supplied by Customer.

       3.2. Equipment. Customer shall provide, at no charge to 2Bridge,
            ---------
services, and equipment (such as copies, fax machines, and modems) as 2Bridge
reasonably requires to perform the Services.

       3.3. Notification.  Customer shall promptly respond to all deliverables
            ------------
or reports requiring Customer acceptance, as well as all requests for
information or Customer materials submitted by 2Bridge. All materials submitted
by 2Bridge requiring such prompt response shall be prominently marked by 2Bridge
as a "Deliverable" and shall specify the time required for response by Customer.
Customer understands and agrees that time is of the essence in the performance
of this Agreement, and failure to cooperate or provide such approvals or
responses in the time required may result in delays or increased cost to
Customer for the Services.

4.   Relationship of Parties
     -----------------------

       4.1. Independent Contractors.  Each party will be and act as an
            -----------------------
independent contractor and not as an agent or partner of, or joint venturer
with, the other party for any purpose related to this Agreement or the
transactions contemplated by this Agreement, and neither party by virtue of this
Agreement will have any right, power or authority to act or create any
obligation, expressed or implied, on behalf of the other party. Each party will
be responsible for the supervision, direction and control of its own personnel
and, except as otherwise set forth herein, shall bear its own costs and expenses
in connection with the Services.

       4.2. Contact Person.  Each party will appoint in writing an employee or
            --------------
agent of such party to act as the "Contact Person" for all communication between
the parties related to the Services. The Contact Person will be responsible for
monitoring the status of the Services and will schedule regular meetings with
both technical and management personnel of each party to review the status of
the Services. The initial Contact Person for each Party is set forth in Exhibit
A hereto, and either party may change its Contact Person upon written notice to
the other.

       4.3. Nonsolicitation. Customer acknowledges and agrees that the employees
            ---------------
and consultants of 2Bridge who perform the Services are valuable assets to
2Bridge and are difficult to replace. Accordingly, Customer agrees that, for a
period of six (6) months after the completion of the Services, it will not offer
employment as an employee,

                                      -2-
<PAGE>

independent contractor, or consultant to any 2Bridge employee or consultant who
performs any of the Services.

       4.4. Services for Others. Customer understands and acknowledges that
            -------------------
2Bridge performs and shall continue to perform services substantially similar to
the Services to other licensees of the Software, and nothing herein shall be
interpreted as restricting 2Bridge or any of its employees from performing such
services for third parties.

5.   Fees and Payments
     -----------------

       5.1. Fees. Customer shall pay 2Bridge the fees set forth on Exhibit A
            ----
attached hereto and incorporated herein by reference. 2Bridge will invoice
Customer upon acceptance by Customer of each milestone set forth on Exhibit C
hereto. All payments for fees and expenses must be made within thirty (30) days
of the date of invoice, or shall then be considered overdue and subject to
interest as provided in Section 5.4 below. If the Customer's procedures require
that an invoice be submitted against a purchase order before payment can be
made, the Customer will be responsible for issuing such purchase order 30 days
before the payment due date.

       5.2. Expenses. Customer shall reimburse all reasonable travel and other
            --------
related expenses incurred by 2Bridge in performance of the Services.

       5.3. Taxes. Customer shall pay or reimburse any and all federal, state,
            -----
dominion, provincial or local sales, use, personal property, excise, or other
taxes, fees or duties arising from or related to this Agreement (other than
taxes based on 2Bridge's net income).

       5.4. Interest. Customer shall pay 2Bridge a late fee of one and one-half
            --------
percent (1.5%) per month, or the highest rate permitted by law, whichever is
less, on the outstanding balance of any fees or expenses not paid within thirty
(30) days of the date of invoice. However, nothing herein shall limit 2Bridge's
right to terminate this Agreement under Section 11.3. Customer shall reimburse
2Bridge for all reasonable costs incurred (including reasonable attorney's fees)
in collecting past due amounts.

       5.5. Conflicting Terms.  No terms, provisions or conditions of any
            -----------------
purchase order or other business form or written authorization used by Customer
will have any effect on the rights, duties or obligations of the parties under,
or otherwise modify, this Agreement, regardless of any failure of 2Bridge to
object to such terms, provisions, or conditions.

       5.6. No Offset.  Fees and expenses due from Customer under this Agreement
            ---------
may not be withheld or offset by Customer for any reason.

6.   Ownership of Work Product
     -------------------------

     6.1.  Application.
           -----------

           (a)  The Application has been specifically ordered and commissioned
                by Customer. 2Bridge agrees that the Application, in its
                entirety, is a "work made for hire" for copyright purposes, with
                all copyrights in the complete Application owned by Customer.

           (b)  To the extent that the Application does not qualify as a work
                for hire under applicable law, and to the extent that the
                Application includes material subject to copyright, patent,
                trade secret, or other proprietary right protection, 2Bridge
                hereby assigns Customer, its successors and assigns, all rights,
                title and interest in and to the Application including without
                limitation all copyrights and equivalent rights in the
                Application throughout the world, and in all renewals and
                extensions of such rights that may be secured under the laws now
                or hereafter in force and effect in the United States of America
                or in any other country or countries.

                                      -3-
<PAGE>

           (c)  At Customer's expense, 2Bridge shall execute and deliver such
                instruments and take such other action as may be requested by
                Customer to perfect or protect Customer's rights in the
                Application and to carry out the assignments contemplated in
                subparagraph (b) of this section. In this regard, 2Bridge agrees
                to cooperate with Customer in the filing and prosecution of any
                copyright or patent applications that Customer may elect to file
                on the Application. Customer acknowledges that 2Bridge has taken
                no action to assist in the registration of the copyrights or the
                Application and will do so only and when requested by Customer.

       6.2. 2Bridge Tools.
            -------------

           (a)  Notwithstanding the foregoing, 2Bridge shall own and retain all
                right, title and interest in the Software, 2Bridge Tools, and
                any technology developed by 2Bridge hereunder which is not
                specifically part of the Application, including without
                limitation all intellectual property rights therein. Customer
                acknowledges and agrees that the Application will be based upon
                the Software and that licenses from 2Bridge to use the Software
                will be required for the operation of the Application. Such
                licenses shall be on 2Bridge's standard terms and conditions for
                such licenses and will be granted separately.

           (b)  License Grant. Subject to Customer's separate license of the
                -------------
                Software, 2Bridge hereby grants to Customer a nontransferable,
                nonexclusive license to use the 2Bridge Tools solely in
                connection with its authorized use of the Software and the
                Application.

7.   Maintenance and Support.  Maintenance and support of the Application is the
     -----------------------
sole responsibility of Customer.  Maintenance and support of the Software may be
contracted for separately by Customer at 2Bridge's then current rates and terms.

8.   Limited Warranty and Limitation of Liability
     --------------------------------------------

       8.1. Limited Warranty. 2Bridge warrants that for a period of ninety (90)
            ----------------
days from 2Bridge's completion of the Application (the "Warranty Period"), the
Application will conform to the Specifications. If the Application is
demonstrated not to conform to the Specifications during the Warranty Period,
2Bridge will, at 2Bridge's option, undertake to correct the Application so it
conforms with such Specifications, or, if in 2Bridge's sole discretion, the
foregoing is not commercially practicable, terminate this Agreement and refund
the fees paid pursuant to Section 5 above.

       8.2. Exclusive Remedies. The foregoing are Customer's sole and exclusive
            ------------------
remedies for breach of warranty. The warranty set forth above is made to and for
the benefit of Customer only.  The warranty will apply only if: (i) the Software
and the Application have been properly installed and used at all times and in
accordance with the instructions for use; (ii) no modification, alteration or
addition has been made to the Application by persons other than 2Bridge; (iii)
the breach of Warranty is not caused, in whole or in part, by code, designs, or
other materials supplied by Customer for inclusion in the Application; and (iii)
the underlying operating system, browser, web server, or web server software has
not been updated, replaced, or otherwise modified.

       8.3. Disclaimer.  EXCEPT AS EXPRESSLY SET FORTH ABOVE, 2BRIDGE MAKES NO
            ----------
WARRANTIES, WHETHER EXPRESS, IMPLIED, OR STATUTORY, REGARDING OR RELATING TO THE
APPLICATION, SOFTWARE, 2BRIDGE TOOLS, DOCUMENTATION, OR ANY MATERIALS OR
SERVICES FURNISHED OR PROVIDED TO CUSTOMER UNDER THIS AGREEMENT, INCLUDING
WITHOUT LIMITATION ANY MAINTENANCE AND SUPPORT. WITHOUT

                                      -4-
<PAGE>

LIMITATION OF THE FOREGOING, 2BRIDGE SPECIFICALLY DISCLAIMS ALL IMPLIED
WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NONINTERRUPTION
OF USE, AND FREEDOM FROM PROGRAM ERRORS WITH RESPECT TO THE APPLICATION,
SOFTWARE, 2BRIDGE TOOLS, DOCUMENTATION, AND OTHER MATERIALS AND SERVICES
DESCRIBED HEREIN. ANY BETA VERSIONS OF THE APPLICATION OR SOFTWARE PROVIDED TO
CUSTOMER ARE DELIVERED "AS IS," WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES.

       8.4. Limitation of Liability.  NOTWITHSTANDING ANYTHING ELSE IN THIS
            -----------------------
AGREEMENT OR OTHERWISE, 2BRIDGE SHALL NOT BE LIABLE OR OBLIGATED WITH RESPECT TO
THE SUBJECT MATTER OF THIS AGREEMENT OR UNDER ANY CONTRACT, NEGLIGENCE, STRICT
LIABILITY OR OTHER LEGAL OR EQUITABLE THEORY FOR ANY AMOUNTS IN EXCESS IN THE
AGGREGATE OF THE FEES PAID TO IT HEREUNDER. IN NO EVENT SHALL 2BRIDGE BE LIABLE
TO ANY CUSTOMER OR ANY THIRD PARTY FOR ANY LOST PROFITS OR COSTS OF PROCUREMENT
OF SUBSTITUTE GOODS OR SERVICES, OR FOR ANY INDIRECT, SPECIAL OR CONSEQUENTIAL
DAMAGES RESULTING FROM THE USE OF THE APPLICATION, SOFTWARE, OR 2BRIDGE TOOLS OR
THE FAILURE OF ANY SUCH ITEMS TO PERFORM, OR FOR ANY OTHER REASON OR ON ANY
THEORY OF LIABILITY, EVEN IF 2BRIDGE HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
DAMAGES.

       8.5. Additional. THE PROVISIONS OF THIS SECTION 8 ALLOCATE RISKS UNDER
            ----------
THIS AGREEMENT BETWEEN CUSTOMER AND 2BRIDGE AND ARE A FUNDAMENTAL PART OF THE
BASIS OF 2BRIDGE'S BARGAIN HEREUNDER. 2BRIDGE WOULD NOT ENTER INTO THIS
AGREEMENT ABSENT SUCH LIMITATION. No action arising out of any breach or claimed
breach of this Agreement or transactions contemplated by this Agreement may be
brought by either party more than one (1) year after the cause of action has
accrued. For purposes of this Agreement, a cause of action will be deemed to
have accrued when a party knew or reasonably should have known of the breach or
claimed breach. No employee, agent, representative or affiliate of 2Bridge has
authority to bind 2Bridge to any oral representations or warranty concerning the
Application or the Software. Any written representation or warranty not
expressly contained in this Agreement will not be enforceable.

9.   Indemnification for Infringement
     --------------------------------

       9.1. Indemnification. 2Bridge shall hold Customer harmless from
            ---------------
liability to third parties resulting from infringement by the Application of any
U.S. copyright or from misappropriation of any trade secret, provided 2Bridge is
promptly notified of any and all threats, claims and proceedings related thereto
and given reasonable assistance and the opportunity to assume sole control over
defense and settlement. 2Bridge will not be responsible for any settlement it
does not approve in writing. The foregoing obligations do not apply with respect
to the Application or portions or components thereof that are: (i) made in whole
or in part in accordance to Customer specifications or supplied to 2Bridge by
Customer for inclusion in the Application, (ii) modified after delivery by
2Bridge, (iii) combined with other products, processes or materials where the
alleged infringement relates to such combination, (iv) where Customer continues
allegedly infringing activity after being notified thereof or after being
informed of modifications that would have avoided the alleged infringement, or
(v) where Customer's use of Application is not strictly in accordance with this
Agreement. Customer will indemnify Company from all damages, settlements,
attorneys' fees and expenses related to any claim of infringement or
misappropriation excluded from Company's indemnity obligation by the preceding
sentence. In the event that Application is held or is believed by 2Bridge to
infringe, 2Bridge shall have the option, at its expense, to (i) modify the
Application to be non-infringing, (ii) obtain for Customer a license to continue
using the Application, or (iii) terminate this Agreement and refund to Customer
the amortized fees paid under

                                      -5-
<PAGE>

this Agreement for the development of the Application, depreciated on a
straight-line basis over a five (5) year period. THE FOREGOING STATES THE ENTIRE
LIABILITY OF 2BRIDGE AND CUSTOMER'S EXCLUSIVE REMEDIES WITH RESPECT TO
INFRINGEMENT OF ANY INTELLECTUAL PROPERTY RIGHTS.

10.  Confidential Information.
     ------------------------

       10.1.  Treatment of Confidential Information. Each party hereto agrees
              -------------------------------------
that it shall use Confidential Information solely in accordance with the
provisions of this Agreement. Neither party shall disclose the Confidential
Information of the other, or permit it to be disclosed, directly or indirectly,
to any third party both during the term of this Agreement and for a period of
five (5) years after termination hereof, without the other party's prior written
consent. Each party agrees to exercise due care in protecting the other's
Confidential Information from unauthorized use and disclosure.

       10.2.  Equitable Relief. In the event of actual or threatened breach of
              ----------------
the provisions of Section 10.1, the parties agree that the non-breaching party
will have no adequate remedy at law and will be entitled to immediate injunctive
and other equitable relief, without bond and without the necessity of showing
actual money damages.

11.  Term and Termination
     --------------------

       11.1.  Term. This Agreement will take effect on the Effective Date and
              ----

              -----------------------
Customer upon thirty (30) days' prior written notice to 2Bridge, with or without
cause, provided that no such termination will entitle Customer to a refund of
any portion of the fees paid by Customer to 2Bridge pursuant to Section 5 above.
In such event, Customer shall immediately pay 2Bridge all amounts due as of the
date of such termination for all work in progress.

       11.3.  Termination by 2Bridge. 2Bridge may, by written notice to

                days after 2Bridge sends an invoice to Customer for such
                payment; or

           (b)  Customer is in material breach of any nonmonetary term,
                condition or provision of this Agreement, which breach, if
                capable of being cured, is not cured within thirty (30) days
                after 2Bridge gives Customer written notice of such breach; or

           (c)  Customer (i) terminates or suspends its business, (ii) becomes
                insolvent, admits in writing its inability to pay its debts as
                they mature, makes an assignment for the benefit of creditors,
                or becomes subject to direct control of a trustee, receiver or
                similar authority, or (iii) becomes subject to any bankruptcy or
                insolvency proceeding under federal or state statutes.

     If any Termination Event occurs, termination will become effective
immediately or on the date set forth in the written notice of termination, and
Customer shall immediately pay to 2Bridge all amounts due as of the date of such
termination for all work in progress.

       11.4.  Survival.  Any termination of this Agreement will not affect
              --------
Sections 4.3, 6.1, 8, 9, 10, 11.4, 11.5, and 14, which shall survive the
termination or expiration of this Agreement. Section 6.2 shall survive the
expiration or termination of this Agreement for any reason other than a
Termination Event.

       11.5.  Return of Materials. Within thirty (30) days after the date of
              -------------------
termination or discontinuance of this Agreement for any reason whatsoever, (i)

and all copies of the foregoing, in whole or in part, all Documentation relating
thereto, and any other Confidential Information in its possession that is in
tangible form, and (ii) 2Bridge shall return all Confidential Information and
other proprietary materials of Customer in its possession. Notwithstanding the
foregoing, 2Bridge may retain a reasonable number of copies of the Application
solely for its archives and internal use.

12.  Nonassignment/Binding Agreement.  Neither this Agreement nor any rights
     -------------------------------
under this Agreement may be assigned or otherwise transferred by Customer, in
whole or in part, whether voluntary or by operation of law, including by way of
sale of assets, merger or consolidation, without the prior written consent of
2Bridge, which consent will not be unreasonably withheld.  2Bridge may
subcontract or assign portions of its obligations and rights under this
Agreement.  Any such subcontract or assignment by 2Bridge is subject to
Customer's consent, which consent shall not be unreasonably withheld or delayed.
Subject to the foregoing, this Agreement will be binding upon and will inure to
the benefit of the parties and their permitted successors and assigns.

     -------
Agreement or required by law must be in writing and must be (a) delivered in

       14.1.  Force Majeure. Neither party will incur any liability to the other
              -------------
party on account of any loss or damage resulting from any delay or failure to
perform all or any part of this Agreement if such delay or failure is caused, in
whole or in part, by events, occurrences, or causes beyond the control and
without negligence of the parties. Such events, occurrences, or causes will
include, without limitation, acts of God, strikes, lockouts, riots, acts of war,
earthquake, fire and explosions, but the inability to meet financial obligations
is expressly excluded.

       14.2.  Waivers; Enforcement. Any waiver of the provisions of this
              --------------------
Agreement or of a party's rights or remedies under this Agreement must be in
writing to be effective. Failure, neglect, or delay by a party to enforce the
provisions of this Agreement or its rights or remedies at any time will not be
construed and will not be deemed to be a waiver of such party's rights under
this Agreement and will not in any way affect the validity of the whole or any
part of this Agreement or prejudice such party's right to take subsequent
action. No exercise or enforcement by either party of any right or remedy under
this Agreement will preclude the enforcement by such party of any other right or
remedy under this Agreement or that such party is entitled by law to enforce.

       14.3.  Severability. If any term, condition, or provision in this
              ------------
Agreement is found to be invalid, unlawful or unenforceable to any extent, the
parties shall endeavor in good faith to agree to such amendments that will
preserve, as far as possible, the intentions expressed in this Agreement. If the
parties fail to agree on such an amendment, such invalid term, condition or
provision will be severed from the remaining terms, conditions and provisions,
which will continue to be valid and enforceable to the fullest extent permitted
by law.

       14.4.  Entire Agreement. This Agreement (including the Exhibits,
              ----------------
Specifications, and any addenda hereto signed by both parties) contains the
entire agreement of the parties with respect to the subject matter of this
Agreement and supersedes all previous communications, representations,

              -----------------
purchase order, acknowledgment or other business form that Customer may use in
connection with the acquisition or licensing of the Software will have any
effect on the rights, duties or obligations of the parties under, or otherwise
modify, this Agreement, regardless of any failure of 2Bridge to object to such
terms, provisions or conditions.

       14.6.  Amendment. This Agreement may not be amended, except by a writing
              ---------
signed by both parties.

not be unreasonably withheld or delayed.

owned and leased) makes such qualification necessary, except for those
jurisdictions in which failure to do so would not have a material adverse effect
on the Company or its business.

          3.2  Capitalization. The Company's capitalization is as follows:
               --------------

Company issuable upon the conversion of the Series B Preferred has been taken.

               ----------------------------------
performance of this Agreement and the Investment Agreements will not result in
any event that results in the creation of any lien, charge or encumbrance upon
any assets of the Company or the suspension, revocation, impairment, forfeiture
or nonrenewal of any material permit, license, authorization or approval
applicable to the Company, its business or operation of any of its assets or

               -------

its Proprietary Rights.  There are no outstanding options, licenses, or

Agreement, nor the carrying on of the Company's business by the employees of the
Company, nor the conduct of the Company's business as proposed, will, to the
Company's knowledge, conflict with or result in a breach of the terms,
conditions or provisions of, or constitute a default under, any contract,

Exceptions attached hereto as Exhibit C is a listing of all patents and
trademarks of the Company.

          3.12 Taxes. All federal, state, local and foreign tax returns
               -----

the Company has been granted extensions of the filing dates, which extensions
have not expired.  All taxes, assessments, fees and other governmental charges
upon the Company, or upon any of its properties, income or franchises, have been
paid or adequate reserves therefor have been set up and have been disclosed in
the Financial Statements (as described in Section 3.18 below) if any of such
taxes are being contested in good faith.  If any of such tax returns have not
been filed or if any such taxes have not been paid or so reserved for, the
failure so to file or to pay would not result in a material adverse effect on
the business, properties, prospects or financial condition of the Company.  The
Company knows of no proposed additional tax assessment that is not provided for
in the Financial Statements.  The Company has no pending or, to the knowledge of
the Company, threatened tax audit.

               ---------------------------                          ---------
as specifically contemplated in this Agreement, the Company is not party to or

employees are satisfactory.  The Company is not bound by or subject to any
written or oral, express or implied, contract, commitment or arrangement with
any labor union and the Company's employees are not represented by any labor
unions nor, to the Company's knowledge, is any union organization campaign in
progress.  There is no strike or other labor dispute involving the Company
pending or, to the knowledge of the Company, threatened, which could have a

contract, proprietary information agreement or any other agreement relating to
the right of any such individual to be employed by, or to contract with, the
Company because of the nature of the business to be conducted by the Company;
and to the Company's knowledge the continued employment by the Company of its
present employees, and the performance of the Company's contracts with its
independent contractors, will not result in any such violation.  The Company has
not received any notice alleging that any such violation has occurred.  No
employee of the Company has been granted the right to continued employment by
the Company or to any material compensation following termination of employment
with the Company.  The Company is not aware that any officer or key employee, or

Company nor does the Company have a present intention to terminate the
employment of any of the foregoing.  The employment of each officer and employee
of the Company is terminable at the will of the Company.  The Company has
complied in all material respects with all applicable state and federal equal
employment opportunity laws and with other laws related to employment.

assuming execution and delivery by the Company, this Agreement will constitute a

          4.2  Brokers and Finders. No agent, broker, investment banker or other
               -------------------
firm or person acting on behalf or under the authority of the Investor is or

     5.   Securities Laws.
          ---------------

          5.1  California Securities Law. THE SALE OF THE SECURITIES WHICH ARE
               -------------------------
THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF
CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR
THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO SUCH
QUALIFICATION IS UNLAWFUL UNLESS AN EXEMPTION FROM SUCH QUALIFICATION IS
AVAILABLE.  THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY
CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED, OR SUCH EXEMPTION BEING
AVAILABLE.

          5.2  Securities Law Representations and Covenants of Investors.
               ---------------------------------------------------------

               (a)  The Company is entering into this Agreement with each
Investor in reliance upon the Investor's representation to the Company, which
the Investor's execution of this Agreement hereby confirms, that the Series B
Preferred to be received by the Investor and the shares of Common Stock issuable
upon the conversion of any Series B Preferred will be acquired

                                      -10-
<PAGE>

for investment for the Investor's own account, not as a nominee or agent, and
not with a view to the sale or distribution of any part thereof in violation of
applicable securities laws. By executing this Agreement, each Investor further
represents that the Investor does not have any contract, undertaking, agreement
or arrangement with any person to sell, transfer, or grant participations to
such person or to any third person, with respect to any of the Series B
Preferred or the shares of Common Stock issuable upon conversion of any of the
Series B Preferred.

               (b) Each Investor understands and acknowledges that the offering
of the Series B Preferred pursuant to this Agreement will not be registered
under the Securities Act on the grounds that the offering and sale of securities
contemplated by this Agreement are exempt from registration pursuant to Section
3(b) or Section 4(2) of the Securities Act or Regulation D promulgated
thereunder, and that the Company's reliance upon such exemption is predicated
upon the Investor's representations set forth in this Agreement.

               (c) Each Investor acknowledges and agrees that the Series B
Preferred and, if issued, the shares of Common Stock issued upon conversion of
the Series B Preferred must be held indefinitely unless they are subsequently
registered under the Securities Act or an exemption from such registration is
available. Each Investor has been advised or is aware of the provisions of Rule
144 promulgated under the Securities Act, which permits limited resale of
securities purchased in a private placement subject to the satisfaction of
certain conditions, including, among other things: the availability of certain
current public information about the Company, the resale occurring not less than
one year after a party has purchased and paid for the security to be sold, the
sale being through an unsolicited 'broker's transaction or in transactions
directly with a market maker (as said term is defined under the Securities
Exchange Act of 1934, as amended) and the number of shares being sold during any
three-month period not exceeding specified limitations.

               (d) Each Investor represents that: (i) the Investor (or his or
her purchaser representative, if any) is an "accredited investor" under the
Securities Act and has such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of the Investor's
prospective investment in the Company, (ii) the Investor has the ability to bear
the economic risks of the Investor's prospective investment; (iii) the Investor
is able, without materially impairing its financial condition, to hold the
Series B Preferred for an indefinite period of time and to suffer complete loss
on its investment; (iv) the Investor is a resident of, or has its principal
office in the state indicated for the Investor as set forth on the Investor
Suitability Questionnaire supplied by the Investor to the Company on or before
the Closing; (v) the Investor understands and has fully considered for purposes
of this investment the risks of this investment and understands that (1) this
investment is suitable only for an investor who is able to bear the economic
consequences of losing its entire investment, (2) the Company has a limited
financial and operating history, (3) the Series B Preferred represent an
extremely speculative investment which involves a high degree of risk of loss,
and (4) there are substantial restrictions on the transferability of, and there
will be no public market for, the Series B Preferred or the Common Stock
issuable upon the conversion of any of the Series B Preferred; accordingly, it
may not be

                                      -11-
<PAGE>

possible for the Investor to liquidate its investment in the Series B Preferred;
(vi) there have been no representations as to the possible future value, if any,
of the Series B Preferred; and (vii) the Investor has received all the
information it has requested from the Company and considers necessary or
appropriate for deciding whether to purchase the Series B Preferred.

do business and is in good standing as a foreign corporation in all
jurisdictions in which the nature of its activities and of its properties (both

jurisdictions in which failure to do so would not have a material adverse effect
on the Company or its business.

          3.2  Capitalization.  The Company's capitalization is as follows:
               --------------

               (a)  upon the filing of the Articles in the form attached hereto
as Exhibit B in the Office of the Secretary of State of California prior to the

of first refusal) proxy or shareholder agreements, or agreements of any kind,
oral or in writing, for the issuance, purchase or acquisition by the Company of
any shares of capital stock of the Company.

Preferred Stock, Series B Preferred Stock, and Common Stock (i) have been duly
authorized and validly issued, (ii) are fully paid and nonassessable, and (iii)
were issued in compliance with all applicable state and federal laws concerning
the issuance of securities. No stock plan, stock purchase, stock option or other
agreement or understanding between the Company and any holder of any equity
securities or rights to purchase equity securities provides for acceleration in
the vesting provisions of such agreement or understanding as the result of any
merger, consolidated sale of stock or assets, change in control or any other
transaction(s) by the Company.

          3.3  No Subsidiaries. The Company does not own, nor does it control,
               ---------------

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

conversion of the Series C Preferred has been taken. This Agreement and the
Investment Agreements, when executed and delivered, each constitutes legally
valid and binding obligations of the Company enforceable against the Company in
accordance with its terms, except to the extent that such enforcement may be
subject to applicable federal or state bankruptcy, insolvency, reorganization,
arrangement, moratorium, fraudulent conveyance or other laws or court decisions
relating to or affecting the rights of creditors generally, and such enforcement
may be limited by equitable principles of general applicability.

          3.5  Validity of Shares. The Series C Preferred are duly authorized
               ------------------
and, when issued, sold and delivered in accordance with the terms of and for the

of all preemptive rights, rights of first refusal, liens, charges, restrictions,
claims and encumbrances imposed by or through the Company, except as
specifically set forth in the Articles, this Agreement or the Investment
Agreements. The Common Stock issuable upon the conversion of the Series C
Preferred has been duly and validly reserved for issuance and, when so issued,
will be duly authorized, validly issued (including, without limitation, issued
in compliance with applicable federal and state securities laws), fully paid and
nonassessable and will be free and clear of all preemptive rights, rights of
first refusal, liens, charges, restrictions on transfer, claims and encumbrances
imposed by or through the Company, except as specifically set forth in the
Articles, this Agreement, or the Investment Agreements.

          3.6  No Conflict with other Instruments. The execution, delivery and
               ----------------------------------
performance of this Agreement and the Investment Agreements will not result in
any event that results in the

creation of any lien, charge or encumbrance upon any assets of the Company or

provision of the Articles or the Company's Bylaws; (b) any provision of any
judgment, decree or order to which the Company is a party or by which it is
bound; (c) any mortgage, indenture, license, contract, obligation or commitment
to which the Company is a party or by which it is bound; or (d) any statute,
rule or governmental regulation applicable to the Company.

               ----------
pending or, to the knowledge of the Company, threatened, or any basis therefor
known to the Company, that questions the validity of this Agreement, or the
Investment Agreements or the right of the Company to enter into any such
agreements, or to consummate the transactions contemplated hereby or thereby, or
which might result, either individually or in the aggregate, in any material
adverse change in the assets, condition, affairs or prospects of the Company,
financially or otherwise, or any change in the current equity ownership of the
Company. The Company is not a party to any such lawsuit or similar action or
proceeding, nor does the Company intend to initiate any such litigation.

          3.8  Title to Properties; Liens and Encumbrances. The Company has good
               -------------------------------------------

Company, and (ii) maintaining the confidentiality of proprietary information of
the Company with no exceptions noted on such agreement. The Company, after
reasonable investigation, is not aware that any of its employees or consultants
is in violation thereof, and the Company will use commercially reasonable
efforts to prevent any such violation.

          3.10 Permits. The Company has all franchises, permits, licenses and
               -------
other similar authority (collectively, "Permits") necessary for the conduct of

of the Company, and believes that it can obtain, without undue burden or
expense, any Permits for the conduct of its business as planned to be conducted.
The Company is not in default in any material respect under any such Permits.

                                      -4-
<PAGE>

conducted and as proposed to be conducted, without any known infringement of the
rights of others. The Company has not received any communication alleging that
the Company has violated or, by conducting its business as proposed, would
violate any of the Proprietary Rights of any other person or entity. The Company
is not aware of any third party which is infringing or violating any of its
Proprietary Rights. There are no outstanding options, licenses, or agreements of
any kind relating to the Proprietary Rights of the Company other than those
incurred in the ordinary course of business, nor is the Company bound by or a
party to any options, licenses or agreements of any kind with respect to the
Proprietary Rights of any other person or entity other than those incurred in
the ordinary course of business. The Company is not aware that any of its
employees is obligated under any contract (including licenses, covenants or
commitments of any nature) or other agreement, or subject to any judgment,
decree or order of any court or administrative agency, that would interfere with
their duties to the Company or that would conflict with the Company's business
as proposed to be conducted. Neither the execution nor delivery of this
Agreement, nor the carrying on of the Company's business by the employees of the
Company, nor the conduct of the Company's business as proposed, will, to the
Company's knowledge, conflict with or result in a breach of the terms,
conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any employee is now obligated. The Company
does not believe it is or will be necessary to utilize any inventions, trade
secrets or proprietary information of any of its employees made prior to their
employment by the Company, except for inventions, trade secrets or proprietary
information that have been assigned to the Company. Set forth in the Schedule of
Exceptions attached hereto as Exhibit C is a listing of all patents and
trademarks of the Company.

          3.12 Taxes. All federal, state, local and foreign tax returns required
               -----
to be filed by the Company have been timely filed, or if not yet filed the
Company has been granted extensions of the filing dates, which extensions have
not expired. All taxes, assessments, fees and other governmental charges upon
the Company, or upon any of its properties, income or franchises, have been paid
or adequate reserves therefor have been set up and have been disclosed in the
Financial Statements (as described in Section 3.18 below) if any of such taxes
are being contested in good faith. If any of such tax returns have not been
filed or if any such taxes have not been paid or so reserved for, the failure so
to file or to pay would not result in a material adverse effect on the business,
properties, prospects or financial condition of the Company. The Company knows
of no proposed additional tax assessment that is not provided for in the
Financial Statements. The Company has no pending or, to the knowledge of the
Company, threatened tax audit.

<PAGE>

knowledge by which it is bound which may involve (i) obligations (contingent or

outstanding under any stock option plan approved by the Board of Directors of
the Company), or (iv) general obligations that a corporation has to its
shareholders under California General Corporation Law, the Articles and the
Bylaws of the Company. The Company is not a guarantor or indemnitor of any
indebtedness of any other person, firm or corporation.

Articles, Bylaws, or of any instrument, judgment, order, writ, decree, license,
permit or contract to which it is a party or by which it is bound or of any
provision of federal or state statute, rule or regulation applicable to the
Company, which violation or violations, either individually or in the aggregate,
would materially and adversely affect the business, assets, liabilities,
financial condition, operations or prospects of the Company. The Company has
avoided every condition, and has not performed any act, the occurrence of which

distribution or other agreement, which is necessary for the conduct of its
business as now being conducted by it, the lack

                                      -6-
<PAGE>

of which could materially and adversely affect the business, properties,
prospects, or financial condition of the Company.

               ----------------
anyone acting on its behalf will offer any of the Series C Preferred or any
similar securities for issuance or sale to, or solicit any offer to acquire any
of the same from, anyone in such a way as to make the issuance and sale of the
Series C Preferred subject to the registration requirements of Section 5 of the
Securities Act of 1933, as amended (the "Securities Act").

accepted accounting principles to be reflected in the Financial Statements,
which, individually or in the aggregate, are not material to the financial
condition of the Company.

               ------------------------------
Statements, the Company has not (i) made any loans or advances to any person,
other than ordinary advances for travel and other ordinary employee related
expenses; (ii) sold, exchanged or otherwise disposed of any of its assets or
rights necessary for the conduct of its business as now being conducted by it,
the lack of which could materially and adversely affect the business,
properties, prospects, or financial condition of the Company; nor has there been
(iii) any material and adverse change in the business assets, liabilities,
financial condition, prospects or operations of the Company; (iv) any
resignation or termination of any key officers of the Company, and the Company,

          5.2  Securities Law Representations and Covenants of Investors.
               ---------------------------------------------------------

               (a)  The Company is entering into this Agreement with each
Investor in reliance upon the Investor's representation to the Company, which
the Investor's execution of this Agreement hereby confirms, that the Series C
Preferred to be received by the Investor and the shares of Common Stock issuable
upon the conversion of any Series C Preferred will be acquired for investment
for the Investor's own account, not as a nominee or agent, and not with a view
to the sale or distribution of any part thereof in violation of applicable
securities laws. By executing this Agreement, each Investor further represents
that the Investor does not have any contract, undertaking, agreement or
arrangement with any person to sell, transfer, or grant participations to such
person or to any third person, with respect to any of the Series C Preferred or
the shares of Common Stock issuable upon conversion of any of the Series C
Preferred.

               (b)  Each Investor understands and acknowledges that the offering
of the Series C Preferred pursuant to this Agreement will not be registered
under the Securities Act on the grounds that the offering and sale of securities
contemplated by this Agreement are exempt from registration pursuant to Section
3(b) or Section 4(2) of the Securities Act or Regulation D promulgated
thereunder, and that the Company's reliance upon such exemption is predicated
upon the Investor's representations set forth in this Agreement.

               (c)  Each Investor acknowledges and agrees that the Series C
Preferred and, if issued, the shares of Common Stock issued upon conversion of
the Series C Preferred must be held indefinitely unless they are subsequently
registered under the Securities Act or an exemption from such registration is
available. Each Investor has been advised or is aware of the provisions of Rule
144 promulgated under the Securities Act, which permits limited resale of
securities purchased in a private placement subject to the satisfaction of
certain conditions, including, among other things: the availability of certain
current public information about the Company, the resale occurring not less than
one year after a party has purchased and paid for the security to be sold, the
sale being through an unsolicited 'broker's transaction or in transactions
directly with a market maker (as said term is defined under the Securities
Exchange Act of 1934, as amended) and the number of shares being sold during any
three-month period not exceeding specified limitations.

               (d)  Each Investor represents that: (i) the Investor (or his or
her purchaser representative, if any) is an "accredited investor" under the
Securities Act and has such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of the Investor's
prospective investment in the Company, (ii) the Investor has the ability to bear
the economic risks of the Investor's prospective investment; (iii) the Investor
is able, without materially impairing its financial condition, to hold the
Series C Preferred for an indefinite period of time and to suffer complete loss
on its investment; (iv) the Investor is a resident of, or has its principal
office in the state indicated for the Investor as set forth on the Investor
Suitability Questionnaire supplied

                                      -11-
<PAGE>

by the Investor to the Company on or before the Closing; (v) the Investor
understands and has fully considered for purposes of this investment the risks
of this investment and understands that (1) this investment is suitable only for
an investor who is able to bear the economic consequences of losing its entire
investment, (2) the Company has a limited financial and operating history, (3)
the Series C Preferred represent an extremely speculative investment which
involves a high degree of risk of loss, and (4) there are substantial
restrictions on the transferability of, and there will be no public market for,
the Series C Preferred or the Common Stock issuable upon the conversion of any
of the Series C Preferred; accordingly, it may not be possible for the Investor
to liquidate its investment in the Series C Preferred; (vi) there have been no
representations as to the possible future value, if any, of the Series C
Preferred; and (vii) the Investor has received all the information it has
requested from the Company and considers necessary or appropriate for deciding
whether to purchase the Series C Preferred.

such qualification necessary, except for those jurisdictions in which failure to
do so would not have a material adverse effect on the Company or its business.

          3.2  Capitalization.  The Company's capitalization is as follows:
               --------------

issuance, purchase or acquisition by the Company of any shares of capital stock
of the Company; and

               (c)  all issued and outstanding shares of the Company's Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock and Common
Stock (i) have been duly authorized and validly issued, (ii) are fully paid and
nonassessable, and (iii) were issued in compliance with all applicable state and
federal laws concerning the issuance of securities. No stock plan, stock
purchase, stock option or other agreement or understanding between the Company
and any holder of any equity securities or rights to purchase equity securities
provides for acceleration in the vesting provisions of such agreement or
understanding as the result of any merger, consolidated sale of stock or assets,
change in control or any other transaction(s) by the Company.

          3.3  No Subsidiaries. The Company does not own, nor does it control,

accordance with its terms, except to the extent that such enforcement may be
subject to applicable federal or state bankruptcy, insolvency, reorganization,
arrangement, moratorium, fraudulent conveyance or other laws or court decisions
relating to or affecting the rights of creditors generally, and such enforcement
may be limited by equitable principles of general applicability.

          3.5  Validity of Shares. The Series D Preferred are duly authorized
               ------------------

state securities laws), fully-paid and non-assessable and will be free and clear
of all preemptive rights, rights of first refusal, liens, charges, restrictions,
claims and encumbrances imposed by or through the Company, except as
specifically set forth in the Articles, this Agreement or the Investment
Agreements. The Common Stock issuable upon the conversion of the Series D
Preferred has been duly and validly reserved for issuance and, when so issued,

               ----------------------------------
performance of this Agreement and the Investment Agreements will not result in
any event that results in the creation of any lien, charge or encumbrance upon

applicable to the Company, its business or operation of any of its assets or
properties or result in any violation of, be in conflict with, or constitute a
default under: (a) any provision of the Articles or the Company's Bylaws; (b)
any provision of any judgment, decree or order to which the Company is a party
or by which it is bound; (c) any mortgage, indenture, license, contract,
obligation or commitment to which the Company is a party or by which it is
bound; or (d) any statute, rule or governmental regulation applicable to the
Company.

          3.7  Litigation. There is no action, proceeding or investigation
               ----------
pending or, to the knowledge of the Company, threatened, or any basis therefor
known to the Company, that questions the validity of this Agreement or the
Investment Agreements or the right of the Company to enter into any such
agreements, or to consummate the transactions contemplated hereby or thereby, or
which might result, either individually or in the aggregate, in any material
adverse change in the assets, condition, affairs or prospects of the Company,
financially or otherwise, or any change in the current equity ownership of the
Company. The Company is not a party to any such lawsuit or similar action or
proceeding, nor does the Company intend to initiate any such litigation.

          3.8  Title to Properties; Liens and Encumbrances. The Company has good
               -------------------------------------------
and marketable title to all of its properties and assets, both real and

him or her during the period of his or her employment with or performance of
services for the Company, and (ii) maintaining the confidentiality of
proprietary information of the Company with no exceptions noted on such
agreement. The Company, after reasonable investigation, is not aware that any of
its employees or consultants is in violation thereof, and the Company will use
commercially reasonable efforts to prevent any such violation.

          3.10 Permits. The Company has all franchises, permits, licenses and
               -------
other similar authority (collectively, "Permits") necessary for the conduct of
its business as now being conducted by it, the lack of which could materially
and adversely affect the business, properties, prospects, or financial condition
of the Company, and believes that it can obtain, without undue burden or
expense, any Permits for the conduct of its business as planned to be conducted.
The Company is not in default in any material respect under any such Permits.

          3.11 Patents, Copyrights and Trademarks. For purposes of this Section
               ----------------------------------
3.11, the term "Proprietary Rights" means patents, trademarks, service marks,
trade names, copyrights,

                                      -4-
<PAGE>

trade secrets or other proprietary rights and processes. To the Company's best
knowledge, the Company owns or possesses sufficient legal rights to all
Proprietary Rights necessary for its business as now conducted and as proposed
to be conducted, without any known infringement of the rights of others. The
Company has not received any communication alleging that the Company has
violated or, by conducting its business as proposed, would violate any of the
Proprietary Rights of any other person or entity. The Company is not aware of
any third party which is infringing or violating any of its Proprietary Rights.
There are no outstanding options, licenses, or agreements of any kind relating
to the Proprietary Rights of the Company other than those incurred in the
ordinary course of business, nor is the Company bound by or a party to any
options, licenses or agreements of any kind with respect to the Proprietary
Rights of any other person or entity other than those incurred in the ordinary
course of business. The Company is not aware that any of its employees is
obligated under any contract (including licenses, covenants or commitments of
any nature) or other agreement, or subject to any judgment, decree or order of
any court or administrative agency, that would interfere with their duties to
the Company or that would conflict with the Company's business as proposed to be
conducted. Neither the execution nor delivery of this Agreement, nor the
carrying on of the Company's business by the employees of the Company, nor the
conduct of the Company's business as proposed, will, to the Company's knowledge,
conflict with or result in a breach of the terms, conditions or provisions of,
or constitute a default under, any contract, covenant or instrument under which
any employee is now obligated. The Company does not believe it is or will be
necessary to utilize any inventions, trade secrets or proprietary information of
any of its employees made prior to their employment by the Company, except for
inventions, trade secrets or proprietary information that have been assigned to
the Company. Set forth in the Schedule of Exceptions is a listing of all patents
and trademarks of the Company.

          3.12 Taxes. All federal, state, local and foreign tax returns required
               -----
to be filed by the Company have been timely filed, or if not yet filed the
Company has been granted extensions of the filing dates, which extensions have
not expired. All taxes, assessments, fees and other governmental charges upon
the Company, or upon any of its properties, income or franchises, have been paid
or adequate reserves therefor have been set up and have been disclosed in the
Financial Statements (as described in Section 3.18 below) if any of such taxes
are being contested in good faith. If any of such tax returns have not been
filed or if any such taxes have not been paid or so reserved for, the failure so
to file or to pay would not result in a material adverse effect on the business,
properties, prospects or financial condition of the Company. The Company knows
of no proposed additional tax assessment that is not provided for in the
Financial Statements. The Company has no pending or, to the knowledge of the
Company, threatened tax audit.

                                      -5-
<PAGE>

               (b)  There are no agreements understandings, instruments,
contracts, proposed transactions, judgments, orders, writs or decrees to which

involve (i) obligations (contingent or otherwise) of, or payments to, the
Company in excess of $50,000, (ii) provisions restricting or affecting in any
material, adverse way the development, manufacture or distribution of the
Company's products or services, or (iii) indemnification by the Company with
respect to infringements of Proprietary Rights (other than indemnification
obligations arising from purchase or sale agreements entered into in the

               (c)  The Company has not (i) declared or paid any dividends, or
authorized or made any distribution upon or with respect to any class or series
of its capital stock, (ii) incurred any indebtedness for money borrowed or any
other liabilities (other than with respect to dividend obligations,

course of business or as disclosed in the Financial Statements described in

$100,000 in the aggregate, (iii) made any loans or advances to any person, other
than ordinary advances for travel expenses, or (iv) sold, exchanged or otherwise
disposed of any of its assets or rights, other than the sale of its inventory in
the ordinary course of business. For the purposes of this subsection (c), all
indebtedness, liabilities, agreements, understandings, instruments, contracts
and proposed transactions involving the same person or entity (including persons
or entities the Company has reason to believe are affiliated therewith) shall be
aggregated for the purpose of meeting any minimum dollar amount.

               (d)  Except for the agreements explicitly contemplated hereby,
and the Company's Articles and Bylaws, the Company is not a party to, and is not
bound by any contract, agreement or instrument which materially affects its
business as now conducted or as proposed to be conducted, its properties or its
financial condition.

               (e)  There are no obligations of the Company to officers,
directors, shareholders, or employees of the Company other than (i) for payment
of salary for services rendered, (ii) reimbursement for reasonable expenses
incurred on behalf of the Company, (iii) for other standard employee benefits
made generally available to all employees (including stock option agreements
outstanding under any stock option plan approved by the Board of Directors of
the Company), or (iv) general obligations that a corporation has to its
shareholders under California General Corporation Law, the Articles and the
Bylaws of the Company. The Company is not a guarantor or indemnitor of any
indebtedness of any other person, firm or corporation.

          3.14 No Defaults, Violations or Conflicts. The Company is not in
               ------------------------------------
violation or default in any material respect of any term or provision of its
Articles, Bylaws, or of any instrument, judgment, order, writ, decree, license,
permit or contract to which it is a party or by which it is bound or of any
provision of any federal or state statute, rule or regulation applicable to the
Company, which violation or violations, either individually or in the aggregate,
would materially and adversely affect the business, assets, liabilities,
financial condition, operations or prospects of the Company. The Company has
avoided every condition, and has not performed any act, the occurrence of which

                                      -6-
<PAGE>

would result in the Company's loss of any right granted under any license,
distribution or other agreement, which is necessary for the conduct of its
business as now being conducted by it, the lack of which could materially and
adversely affect the business, properties, prospects, or financial condition of
the Company.

          3.15 Insurance. The Company has obtained insurance as specified in the
               ---------
Company's Schedule of Exceptions. The Company is not aware of any pending or
threatened claims against the Company for personal injuries or property damages
which materially and adversely affect the business, assets, liabilities,
financial condition, operations or prospects of the Company.

          3.16 Private Offering. The Company agrees that neither the Company nor
               ----------------
anyone acting on its behalf will offer any of the Series D Preferred or any
similar securities for issuance or sale to, or solicit any offer to acquire any
of the same from, anyone in such a way as to make the issuance and sale of the
Series D Preferred subject to the registration requirements of Section 5 of the
Securities Act of 1933, as amended (the "Securities Act").

          3.17 Prior Registration Rights. Except as provided in the Rights
               -------------------------
Agreement, the Company is not under any contractual obligation, and has not
granted any rights, to register under the Securities Act any of its securities
that are presently outstanding or may subsequently be issued under such
obligation. To the Company's knowledge, except as contemplated in the Second
Amended and Restated Voting Agreement, dated as of July 23, 1999, among the

ended and its unaudited financial statements (including balance sheet, income
statement and statement of cash flows) as of March 31, 1999 and for the three

complete and correct in all material respects, have been prepared in accordance
with generally accepted accounting principles applied on a consistent basis
throughout the period indicated, except as disclosed therein, and present fairly
the financial condition and results of operations of the Company as of the dates
and for the periods presented. Except as set forth in the Financial Statements,
the Company has no liabilities, contingent or otherwise, other than liabilities
incurred in the ordinary course of business and not required under generally
accepted accounting principles to be reflected in the Financial Statements,
which, individually or in the aggregate, are not material to the financial
condition of the Company.

          3.19 Changes in Financial Condition. Since the date of the Financial
               ------------------------------
Statements, the Company has not (i) made any loans or advances to any person,
other than ordinary advances for travel and other ordinary employee related
expenses; (ii) sold, exchanged or otherwise disposed of any of its assets or

present employees, and the performance of the Company's contracts with its
independent contractors, will not result in any such violation. The Company has
not received any notice alleging that any such violation has occurred. No
employee of the Company has been granted the right to continued employment by
the Company or to any material compensation following termination of employment
with the Company. The Company is not aware that any officer or key employee, or

          4.1  Authorization. When executed and delivered by the Investor, and
               -------------
assuming execution and delivery by the Company, this Agreement will constitute a
valid obligation of the Investor, enforceable in accordance with its terms,
except to the extent that such enforcement may be subject to applicable federal
or state bankruptcy, insolvency, reorganization, arrangement, moratorium,
fraudulent conveyance or other laws or court decisions relating to or affecting

firm or person acting on behalf or under the authority of the Investor is or

THE SUBJECT OF THIS AGREEMENT HAS NOT BEEN QUALIFIED WITH THE COMMISSIONER OF
CORPORATIONS OF THE STATE OF CALIFORNIA AND THE ISSUANCE OF SUCH SECURITIES OR
THE PAYMENT OR RECEIPT OF ANY PART OF THE CONSIDERATION THEREFOR PRIOR TO SUCH
QUALIFICATION IS UNLAWFUL UNLESS AN EXEMPTION FROM SUCH QUALIFICATION IS
AVAILABLE. THE RIGHTS OF ALL PARTIES TO THIS AGREEMENT ARE EXPRESSLY CONDITIONED
UPON SUCH QUALIFICATION BEING OBTAINED, OR SUCH EXEMPTION BEING AVAILABLE.

          5.2  Securities Law Representations and Covenants of Investors.
               ---------------------------------------------------------

               (a)  The Company is entering into this Agreement with each
Investor in reliance upon the Investor's representation to the Company, which
the Investor's execution of this Agreement hereby confirms, that the Series D
Preferred to be received by the Investor and the shares of Common Stock issuable
upon the conversion of any Series D Preferred will be acquired for investment
for the Investor's own account, not as a nominee or agent, and not with a view
to the sale or distribution of any part thereof in violation of applicable
securities laws. By executing this Agreement, each Investor further represents
that the Investor does not have any contract, undertaking, agreement or
arrangement with any person to sell, transfer, or grant participations to such
person or to any third person, with respect to any of the Series D Preferred or
the shares of Common Stock issuable upon conversion of any of the Series D
Preferred.

                                      -10-
<PAGE>

               (b)  Each Investor understands and acknowledges that the offering
of the Series D Preferred pursuant to this Agreement will not be registered
under the Securities Act on the grounds that the offering and sale of securities
contemplated by this Agreement are exempt from registration pursuant to Section
4(2) of the Securities Act or Regulation D promulgated thereunder, and that the
Company's reliance upon such exemption is predicated upon the Investor's
representations set forth in this Agreement.

               (c)  Each Investor acknowledges and agrees that the Series D
Preferred and, if issued, the shares of Common Stock issued upon conversion of
the Series D Preferred must be held indefinitely unless they are subsequently
registered under the Securities Act or an exemption from such registration is
available. Each Investor has been advised or is aware of the provisions of Rule
144 promulgated under the Securities Act, which permits limited resale of
securities purchased in a private placement subject to the satisfaction of
certain conditions, including, among other things: the availability of certain
current public information about the Company, the resale occurring not less than
one year after a party has purchased and paid for the security to be sold, the
sale being through an unsolicited broker's transaction or in transactions
directly with a market maker (as said term is defined under the Securities
Exchange Act of 1934, as amended) and the number of shares being sold during any
three-month period not exceeding specified limitations.

               (d)  Each Investor represents that: (i) the Investor (or his or
her purchaser representative, if any) is an "accredited investor" under the
Securities Act and has such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of the Investor's
prospective investment in the Company, (ii) the Investor has the ability to bear
the economic risks of the Investor's prospective investment; (iii) the Investor
is able, without materially impairing its financial condition, to hold the
Series D Preferred for an indefinite period of time and to suffer complete loss
on its investment; (iv) the Investor is a resident of, or has its principal
office in the state indicated for the Investor as set forth on the Investor
Suitability Questionnaire supplied by the Investor to the Company on or before
the Closing; (v) the Investor understands and has fully considered for purposes
of this investment the risks of this investment and understands that (1) this
investment is suitable only for an investor who is able to bear the economic
consequences of losing its entire investment, (2) the Company has a limited
financial and operating history, (3) the Series D Preferred represent an
extremely speculative investment which involves a high degree of risk of loss,
and (4) there are substantial restrictions on the transferability of, and there
will be no public market for, the Series D Preferred or the Common Stock
issuable upon the conversion of any of the Series D Preferred; accordingly, it
may not be possible for the Investor to liquidate its investment in the Series D
Preferred; (vi) there have been no representations as to the possible future
value, if any, of the Series D Preferred; and (vii) the Investor has received
all the information it has requested from the Company and considers necessary or
appropriate for deciding whether to purchase the Series D Preferred.

shall be treated for all purposes as the record holder(s) of, the Shares
represented thereby (and such Shares
<PAGE>

shall be deemed to have been issued) immediately prior to the close of business
on the date or dates upon which this Warrant is exercised.

          (b)  Net Issue Exercise.  In lieu of exercising this warrant pursuant
               ------------------
to Section 1(a) hereof, the Holder may elect to receive a number of Shares equal
to the value (as determined below) of this Warrant (or the portion thereof being
canceled) by surrender of this Warrant at the principal office of the Company
together with Notice of Exercise in which alternative No. 1 is initiated by the
Holder.  In such event, the Company shall issue to the Holder a number of Shares
computed using the following formula:


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

Where X   =    the number of Shares to be issued to the Holder.

      Y   =    the number of Shares subject to this warrant.

      A   =    the fair market value of one share of the Company's Common Stock.

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

          (c)  Fair market Value.  For purposes of this Section 1, the fair
               -----------------
market value of the Company's Common Stock shall mean:

               (i)   The average of the closing bid and asked prices of the
Company's Common Stock quoted in the Over-The-Counter Market Summary or the
closing price quoted on any exchange on which the Common Stock is listed,
whichever is applicable, as published in the Western Edition of The Wall Street
                                                                ---------------
Journal for the ten trading days prior to the date of determination of fair
- -------
market value;

               (ii)  If the Company's Common Stock is not traded Over-The-
Counter or on an exchange, fair market value of the Common Stock per share shall
be the price per share as determined by the Company's Board of Directors.
Receipt and acknowledgment of this warrant by the Holder shall be definitely
deemed to be an acknowledgment and acceptance of any such fair market value
determination by the Company's Board of Directors as the final and binding
determination of such value for purposes of this Agreement.

          (d)  Stock Certificates.  In the event of any exercise of the rights
               ------------------
represented by this Warrant, certificates for the shares of Common Stock so
purchased shall be delivered to the Holder within a reasonable time and, unless
this Warrant has been fully exercised or has expired, a new Warrant representing
the shares with respect to which this Warrant shall not have been exercised
shall also be issued to the Holder within such time.

                                       2
<PAGE>

          (e)  Condition of Exercise  Unless exercised pursuant to an effective
               ---------------------
registration statement under the Act which includes the Shares so exercised, it
shall be a condition to any exercise of this Warrant that the Company shall have
received, at the time of such exercise, a representation in writing from the
Holder in the form attached hereto as Exhibit A-1, that the Shares being issued
                                      -----------
upon exercise are being acquired for investment and not with a view to any sale
or distribution thereof.

     2.   Stock Fully Paid; Reservation of Shares.  All of the Shares issuable
          ---------------------------------------
upon the exercise of the rights represented by this Warrant will, upon issuance
and receipt of the Exercise Price therefor, be fully paid and nonassessable, and
free from all preemptive rights, rights of first refusal or first offer, taxes,
liens and charges with respect to the issuance thereof.  During the period
within which the rights represented by this Warrant may be exercised, the
Company shall at all times have authorized and reserved for issuance sufficient
shares of its Common Stock to provide for the exercise of the rights represented
by this Warrant.

     3.   Adjustment of Exercise Price and Number of Shares.  Subject to the
          -------------------------------------------------
provisions of Section 13 hereof, the number and kind of Shares purchasable upon
the exercise of this Warrant and the Exercise Price therefor shall be subject to
adjustment from time to time upon the occurrence of certain events, as follows:

          (a)  Stock Splits, Dividends and Combinations.  In the event that the
               ----------------------------------------
Company shall at any time subdivide the outstanding shares of Common Stock, or
shall issue a stock dividend on its outstanding shares of Common Stock, the
number of Shares issuable upon exercise of this Warrant immediately prior to
such subdivision or to the issuance of such stock dividend shall be
proportionately increased, and the Exercise Price shall be proportionately
decreased, and in the event that the Company shall at any time combine the
outstanding shares of Common Stock, the number of Shares issuable upon exercise
of this Warrant immediately prior to such combination shall be proportionately
decreased, and the Exercise Price shall be proportionately increased, effective
at the close of business on the date of such subdivision, stock dividend or
combination, as the case may be.

          (b)  Adjustments.  If at any time the Company issues or sells any
               -----------
shares of its Common Stock (other than shares of Common Stock issued on
conversion of Series A Preferred Stock or issued either directly or upon
exercise of options or warrants to employees, officers, directors and
independent contractors of the Company and its subsidiaries pursuant to stock
purchase or stock option plans, agreements or other similar arrangements that
are approved by the Board of Directors (the "Compensatory Shares") or issued
either directly or upon exercise of options or warrants issued in connection
with equipment lease financing or other similar financing arrangements approved
by the Board of Directors (the "Lease Financing Shares") for a consideration per
share less than the then effective Exercise Price, then and in each such case,
the Exercise Price for the Shares will be reduced to a price (calculated to the
nearest cent) determined by multiplying such applicable Exercise Price by a
fraction (a) the numerator of which will be the number of shares of Common Stock
outstanding (or so deemed) immediately prior to such issuance or sale plus the
number of shares of Common Stock which the aggregate consideration received by
the Company for such issuance or sale would purchase at such applicable Exercise
Price, and (b) the denominator of which will be the number of shares of Common
Stock outstanding (or so deemed) immediately after the

                                       3
<PAGE>

Common Stock proposed to be issued or sold is issued or sold; provided that such
fraction will in no event be greater than one (1). For purposes of this Section
3(b), the Shares, the shares of Common Stock issuable upon conversion of the
Series A Preferred Stock, the Compensatory Shares, and the Lease Financing
Shares (to the extent issued or subject to outstanding options) will be deemed
to be outstanding on the date hereof.

          For the purpose of making any adjustment in the Exercise Price as
provided above, the consideration received by the Company for any issuance or
sale of Common Stock will be computed:

                    (A)  to the extent it consists of cash, as the amount of
cash received by the Company before deduction of any offering expenses payable
by the Company and any underwriting or similar commissions, compensation, or
concessions paid or allowed by the Company in connection with such issuance or
sale;

                    (B)  to the extent it consists of property other than cash,
at the fair market value of that property as determined in good faith by the
Company's Board of Directors; and

                    (C)  if Common Stock is issued or sold together with other
stock or securities or other assets of the Company for a consideration which
covers both, as the portion of the consideration so received that may be
reasonably determined in good faith by the Board of Directors to be allocable to
such Common Stock.

          If the Company (a) grants any rights or options (other than rights or
options issued in connection with the Compensatory Shares and the Lease
Financing Shares) to subscribe for, purchase, or otherwise acquire shares of
Common Stock, or (b) issues or sells any security convertible into shares of
Common Stock, then, in each case, the price per share of Common Stock issuable
on the exercise of the rights or options or the conversion of the securities
will be determined by dividing the total amount, if any, received or receivable
by the Company as consideration for the granting of the rights or options or the
issuance or sale of the convertible securities, plus the minimum aggregate
amount of additional consideration payable to the Company on exercise or
conversion of the securities, by the maximum number of shares of Common Stock
issuable on the exercise of conversion.  Such granting or issuance or sale will
be considered to be an issuance or sale for cash of the maximum number of shares
of Common Stock issuable on exercise or conversion at the price per share
determined under this subsection, and the Exercise Price for the Shares will be
adjusted as above provided to reflect (on the basis of that determination) the
issuance or sale.  No further adjustment of the Exercise Price for the Shares
will be made as a result of the actual issuance of shares of Common Stock on the
exercise of any such rights or options or the conversion of any such convertible
securities, except as set forth below.

          Upon the redemption or repurchase of any such securities or the
expiration or termination of the right to convert into, exchange for, or
exercise with respect to, Common Stock, the Exercise Price for the Shares will
be readjusted to such price as would have been obtained had the adjustment made
upon their issuance been made upon the basis of the issuance of only the number
of such securities as were actually converted into, exchanged for, or exercised
with respect to, Common

                                       4
<PAGE>

Stock. If the purchase price or conversion or exchange rate provided for in any
such security changes at any time, then, upon such change becoming effective,
the Exercise Price then in effect will be readjusted forthwith to such price as
would have been obtained had the adjustment made upon the issuance of such
securities been made upon the basis of (a) the issuance of only the number of
shares of Common Stock theretofore actually delivered upon the conversion,
exchange or exercise of such securities, and the total consideration received
therefor, and (b) the granting or issuance, at the time of such change, of any
such securities then still outstanding for the consideration, if any, received
by the Company therefor and to be received on the basis of such changed price or
rate.

          (c)  Recapitalizations.  If at any time or from time to time there
               -----------------
shall be a recapitalization of the Common Stock, or Series A Preferred Stock
(other than a subdivision, combination or merger or sale of assets transaction
provided for elsewhere in this Section D), provision shall be made so that the
Holder of this Warrant will thereafter be entitled to receive upon exercise of
this Warrant the number of shares of stock or other securities or property of
the Company or otherwise, to which a Holder of Common Stock would have been
entitled on such recapitalization.  In any such case, appropriate adjustment
shall be made in the application of the provisions of this Section 3 with
respect to the rights of the Holder of this Warrant after the recapitalization
to the end that the provisions of this Section 3 (including adjustment of the
Exercise Price then in effect and the number of shares issuable upon exercise of
this Warrant) shall be applicable after that event in as nearly an equivalent
manner as may be practicable.

          (d)  Certificate as to Adjustments.  Upon the occurrence of each
               -----------------------------
adjustment or readjustment of the Exercise Price pursuant to this Section 3, the
Company at its expense promptly will compute such adjustment or readjustment in
accordance with the terms hereof and prepare and furnish to the Holder a
certificate setting forth such adjustment or readjustment and showing in detail
the facts upon which such adjustment or readjustment is based.  The Company,
upon the written request at any time of the Holder, will furnish or cause to be
furnished to Holder a like certificate setting forth (i) such adjustments and
readjustments, (ii) the Exercise Price for the Shares at the time in effect, and
(iii) the number of shares of Common Stock which at the time would be received
upon the exercise of this Warrant by the Holder.

          (e)  Reservation of Stock Issuable Upon Exercise.  The Company at all
               -------------------------------------------
times will reserve and keep available out of its authorized but unissued shares
of Common Stock solely for the purpose of effecting the exercise of this Warrant
such number of its shares of Common Stock as from time to time will be
sufficient to effect the exercise of all then exercisable Shares; and if at any
time the number of authorized but unissued shares of Common Stock is not
sufficient to effect the exercise of all then unexercised Shares, in addition to
such other remedies as may be available to Holder for such failure, the Company
will take such corporate action as, in the opinion of its counsel, may be
necessary to increase its authorized but unissued shares of Common Stock to such
number of shares as will be sufficient for such purpose.

          (f)  Notices.  Upon any adjustment of the Exercise Price and any
               -------
increase or decrease in the number of Shares purchasable upon the exercise of
this Warrant in accordance with

                                       5
<PAGE>

Section 3 hereof, then, and in each such case, the Company, within thirty (30)
days thereafter, shall give written notice thereof to the Holder at the address
of such Holder as shown on the books of the Company which notice shall state the
Exercise Price as adjusted and, if applicable, the increased or decreased number
of Shares purchasable upon the exercise of this Warrant, setting forth in
reasonable detail the method of calculation of each. Any written notice by the
Company required or permitted hereunder shall be given by hand delivery or first
class mail, postage prepaid, addressed to the Holder at the address shown on the
books of the Company for the Holder.

     4.   Registration Rights.  The Company hereby covenants and agrees as
          -------------------
follows:

          (a)  Definitions. As used in this Section 4, the following terms shall
               -----------
have the following respective meanings:

               (i)    "Public Offering" means any registered offering of the
Company's securities solely for cash, other than a registration (i) on Form S-8
or any form which does not include substantially the same information as would
be required to be included in a registration statement covering the sale of the
Registrable Securities, or (ii) with respect to an employee benefit plan, or
(iii) solely in connection with a Rule 145 transaction under the 1933 Act.
"Initial Public Offering" means the Company's first Public Offering.

               (ii)   The terms "register," "registered" and "registration"
refer to a registration effected by preparing and filing a registration
statement or similar document in compliance with the 1933 Act, and the
declaration or ordering of the effectiveness of such registration statement or
document by the SEC.

               (iii)  The term "Registrable Securities" means: (i) the Shares,
(ii) the Common Stock issued or issuable upon conversion of the Series A
Preferred Stock or the Common Stock Warrants dated as of January 17, 1997; and
(iii) any Common Stock of the Company issued (or issuable upon the conversion or
exercise of any warrant, right or other security which is issued) by way of a
stock split, stock dividend, recapitalization, merger or other distribution with
respect to, or in exchange for, or in replacement of, such Preferred Stock or
Common Stock, excluding in all cases, however, any Registrable Securities sold
by a person in a transaction in which its registration rights are not assigned.

          (b)  Piggy-back Registration Rights.
               ------------------------------

               (i)    Piggy-back Rights.  If (but without any obligation to do
                      -----------------
so) the Company proposes to register (including for this purpose a registration
effected by the Company for shareholders other than Holder) any of its
securities in connection with a Public Offering, the Company shall promptly give
Holder written notice of such registration, at least 30 days prior to the filing
of any registration statement under the Securities Act of 1933, as amended
(hereinafter, the "1933 Act"), together with a list of the jurisdictions in
which the Company intends to attempt to qualify such securities under applicable
state securities laws. Upon the written request of Holder given within 20 days
after delivery of such written notice by the Company, the Company shall, subject

                                       6
<PAGE>

to the provisions of Section 4(b)(ii) below, use its best efforts to cause to be
registered under the 1933 Act all of the Shares that Holder has requested to be
registered.  If Holder decides not to include all of its Shares in any
registration statement thereafter filed by the Company, Holder shall
nevertheless continue to have the right to include any of its Shares in any
subsequent registration statement or statements as may be filed by the Company
with respect to offerings of its securities, all upon the terms and conditions
set forth herein.

               (ii)   Underwriting Requirements in Piggy-back Registration.  If
                      ----------------------------------------------------
the registration statement under which the Company gives notice under this
Section 4(b) is for an underwritten offering, the Company shall so advise
Holder. The right of Holder to registration pursuant to Section 4(b)(i) above
shall be conditioned upon Holder's participation in such underwriting and the
inclusion of Holder's Shares in the underwriting to the extent provided herein.
Holders of Registrable Securities proposing to distribute their securities
through such underwriting (each, a "Participating Holder") shall (together with
the Company and any other holders of Company securities distributing their
securities through such underwriting) enter into an underwriting agreement in
customary form with the underwriter or underwriters selected for underwriting by
the Company. Notwithstanding any other provision of this Section 4(b), if the
underwriter determines that marketing factors require a limitation of the number
of shares to be underwritten, the underwriter may (subject to the allocation
priority set forth below) exclude some or all Shares from such registration and
underwriting. Further, notwithstanding anything to the contrary herein, no
reduction shall be made with respect to securities offered by the Company for
its own account under this Section 4(b). The Company shall so advise all persons
requesting registration, and the number of shares of securities that may be
included in the registration and underwriting shall be allocated in the
following manner. The number of shares that may be included in the registration
and underwriting shall be allocated (i) first to the Company; (ii) second to the
Participating Holders, in proportion, as nearly as practicable, to the
respective amounts of Registrable Securities held by such Participating Holders;
and (iii) third, to any other shareholders of the Company (other than
Participating Holders) on a pro rata basis. In no event shall the amount of
securities of the selling Participating Holders included in the registration be
reduced below twenty-five percent (25%) of the total amount of securities
included in such registration, unless such offering is the Initial Public
Offering and such registration does not include shares of any other selling
shareholders, in which event any or all of the Registrable Securities of the
Holders may be excluded in accordance with the immediately preceding sentence.
In no event will shares of any other selling shareholder be included in such
registration which would reduce the number of shares which may be included by
Holders without the written consent of Holders of not less than a majority of
the Registrable Securities proposed to be sold in the offering. If any Holder
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.

     5.   Reports Under Securities Exchange Act of 1934 as amended (hereinafter
          ---------------------------------------------------------------------
"1934 Act"). With a view of making available to Holder the benefits of Rule 144
- -----------
promulgated under the 1933 Act and any other rule or regulation of the SEC that
may at any time permit a Holder to sell securities of the Company to the public
without registration, the Company agrees to:

                                       7
<PAGE>

          (a)  use its best efforts to make and keep public information
available, as those terms are understood and defined in SEC Rule 144, at all
times after 90 days following the effective date of the registration statement
filed by the Company in connection with its Initial Public Offering;

          (b)  take such action, including the voluntary registration of its
Common Stock under Section 12 of the 1934 Act, as is necessary to enable Holder
to utilize Form S-3 for the sale of the Shares, such action to be taken as soon
as practicable after the end of the fiscal year in which the registration of the
Company's Initial Public Offering is declared effective;

          (c)  use its best efforts to file with the SEC in a timely manner all
reports and other documents required of the Company under the 1933 Act and the
1934 Act; and

          (d)  furnish to Holder, so long as Holder owns any Shares, forthwith
upon request:  (i) a written statement by the Company that it has complied with
the reporting requirements of SEC Rule 144 (at any time after 90 days after the
effective date of the registration statement filed by the Company in connection
with its Initial Public Offering), the 1933 Act and the 1934 Act (at any time
after it has become subject to such reporting requirements), or that it
qualifies as a registrant whose securities may be resold pursuant to Form S-3
(at any time after it so qualifies); (ii) a copy of the most recent annual or
quarterly report of the Company and such other reports and documents so filed by
the Company; and (iii) such other information as may be reasonably requested in
availing any Holder of any rule or regulation of the SEC or any state securities
authorities which permits the selling of any such securities without
registration or pursuant to such form.

     6.   Information Rights.
          ------------------

          (a)  As long as Holder holds the Shares, the Company will deliver it
the following information and reports:

               (i)    As soon as practicable after the end of each fiscal year
of the Company, and in any event within 90 days thereafter, an audited balance
sheet of the Company as of the end of such year and audited statements of
income, shareholders' equity and changes in statement of cash flow for such
year, which year end financial reports will be in reasonable detail and will be
accompanied by a report and opinion thereon of independent public accountants of
nationally recognized standing selected by the Company.

               (ii)   As soon as practicable after the end of each fiscal
quarter, and in any event within 45 days thereafter, balance sheets of the
Company and its subsidiaries, if any, as of the end of such quarter, and
statements of income and cash flow for each quarter and for the current fiscal
year to date, including comparisons to that fiscal year's Annual Plan of results
for the quarter, and year-to-date and to the prior year comparable period,
prepared in accordance with generally accepted accounting principles, with the
exception that no notes need be attached to such statements and year-end audit
adjustments need not be made.

                                       8
<PAGE>

          (b)  Holder agrees to, and to use its best efforts to insure that its
authorized representatives, keep confidential the information provided to it
pursuant to Section 6(a) above and any other information furnished to it which
the Company identifies as being confidential or proprietary (so long as such
information is not in the public domain), except that such Holder may disclose
such proprietary or confidential information to any partner, subsidiary or
parent of such Holder for the purpose of evaluating its investing in the Company
as long as such partner, subsidiary or parent is advised of the confidentiality
provisions of this Section 6.

     7.   Restrictions on Transfer.
          ------------------------

          (a)  Holder agrees not to make any disposition of all or any portion
of the Shares or the Warrant unless and until:

               (i)    There is then in effect a registration statement under the
1933 Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

               (ii)   Holder shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition, and the transferee has
agreed in writing to be bound by this Section 7. If reasonably requested by the
Company, Holder shall furnish the Company with an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will not require registration
of such shares under the 1933 Act. Notwithstanding the foregoing, the
restrictions imposed upon the transferability of any of the Shares or rights to
acquire Shares do not apply to transfers from the beneficial owner of any of the
aforementioned securities to its nominee or from such nominee to its beneficial
owners, and shall terminate as to any particular Shares when a letter shall have
been issued to Holder at its request by the staff of the Securities and Exchange
Commission or a ruling shall have been issued to the Holder at its request by
such Commission stating that no action shall be recommended by such staff or
taken by such Commission, as the case may be, if such security is transferred
without registration under the 1933 Act in accordance with the conditions set
forth in such letter or ruling and such letter or ruling specifies that no
subsequent restrictions on transfer are required. It is agreed that the Company
will not require opinions of counsel for transactions made pursuant to Rule 144
except in unusual circumstances.

     8.   Market Standoff Agreement.  Holder agrees, in connection with the
          -------------------------
Company's Initial Public Offering that, upon request of the Company or the
underwriters managing any underwritten offering of the Company's securities, not
to sell, make any short sale of, loan, grant any option for the purchase of, or
otherwise dispose of any Common Stock of the Company (other than those Common
Stock shares included in the registration) without the prior written consent of
the Company or such underwriters, as the case may be, for such period of time
(not to exceed 180 days) from the effective date of such registration as may be
requested by the underwriters; provided that such covenants shall apply only if
each officer and director of the Company who owns at least 1% of the Common
Stock of the Company (on a fully diluted basis) also agrees to such
restrictions.  In order to enforce the foregoing covenant, the Company may
impose stop-transfer instructions with respect to the

                                       9
<PAGE>

Registrable Securities of each Holder (and the shares or securities of every
other person subject to the foregoing restriction) until the end of such period.

     9.   Legends.
          -------

          (a)  All certificates evidencing the Shares upon exercise of this
Warrant, will bear the following legends:

          THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
          REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND
          HAVE BEEN TAKEN BY THE ISSUEE FOR INVESTMENT PURPOSES. SAID
          SHARES MAY NOT BE SOLD OR TRANSFERRED UNLESS (A) THEY HAVE BEEN
          REGISTERED UNDER SAID ACT, (B) THE TRANSFER AGENT (OR THE
          COMPANY IF THEN ACTING AS ITS OWN TRANSFER AGENT) IS PRESENTED
          WITH EITHER A WRITTEN OPINION SATISFACTORY TO COUNSEL FOR THE
          COMPANY OR A "NO-ACTION" OR INTERPRETIVE LETTER FROM THE
          SECURITIES AND EXCHANGE COMMISSION TO THE EFFECT THAT SUCH
          REGISTRATION IS NOT REQUIRED UNDER THE CIRCUMSTANCES OF SUCH
          SALE OR TRANSFER, (C) THEY ARE SOLD IN COMPLIANCE WITH RULE 144
          OR RULE 144A UNDER THE ACT, OR (D) OTHER EVIDENCE REASONABLY
          SATISFACTORY TO THE COMPANY IS PRESENTED TO THE COMPANY TO THE
          EFFECT THAT SUCH REGISTRATION IS NOT REQUIRED.

          THE SHARES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
          TRANSFER RESTRICTIONS AS SET FORTH IN WARRANT NO. ______ DATED
          NOVEMBER ___, 1997, A COPY OF WHICH IS ON FILE WITH THE
          SECRETARY OF THE COMPANY.

          (b)  The certificates evidencing the Shares will also bear any legend
required by the Commissioner of Corporations of the State of California or
required pursuant to any state, local or foreign law governing such securities.

          (c)  The Company shall be obligated to reissue promptly unlegended
certificates at the request of Holder thereof if Holder shall have obtained an
opinion of counsel (which counsel may be counsel to the Company) reasonably
acceptable to the Company to the effect that the securities proposed to be
disposed of may lawfully be so disposed of without registration, qualification
or legend.  Any legend endorsed on an instrument pursuant to applicable state
securities laws and the stop-transfer instructions with respect to such
securities shall be removed upon receipt by the Company of an order of the
appropriate blue sky authority authorizing such removal.

          (d)  Subject to this Section 9, the Company may instruct its transfer
agent not to register the transfer of all or a part of this Warrant, or any of
the Shares, unless one of the conditions specified in the above legend is
satisfied.

     10.  Fractional Shares.  No fractional shares of Common Stock will be
          -----------------
issued in connection with any exercise hereunder, but in lieu of such fractional
shares the Company shall make a cash payment therefor upon the basis of the
Exercise Price then in effect.

     11.  Representations and Warranties by the Company.
          ---------------------------------------------

          (a)  Due Authority.  The execution and delivery by the Company of this
               -------------
Warrant and the performance of all obligations of the Company hereunder,
including the issuance to Holder of the right to acquire Shares, have been duly
authorized by all necessary corporate action on the part of the Company.  This
Warrant is not inconsistent with the Company's Amended and Restated Articles of
Incorporation, and does not contravene any law or governmental rule, regulation
or order applicable to it, and does not and will not contravene any provision
of, or constitute a default under, any indenture, mortgage, contract or other
instrument to which it is a party or by which it is bound.  This Warrant
constitutes a legal, valid and binding agreement of the Company, enforceable in
accordance with its respective terms.

          (b)  Consents and Approvals.  No consent or approval of, giving of
               ----------------------
notice to, registration with, or taking of any other action in respect of any
state, Federal or other governmental authority or agency is required with
respect to the execution, delivery and performance by the Company of its
obligations under this Warrant, except for the filing of notices pursuant to
Regulation D under the 1933 Act and any filing required by applicable state
securities law, which filings shall be made by the time required thereby.

          (c)  Issued Securities.  All issued and outstanding shares of Common
               -----------------
Stock, Preferred Stock or any other securities of the Company have been duly
authorized and validly issued and are fully paid and nonassessable.  All
outstanding shares of Common Stock, Preferred Stock and any other securities
were issued in full compliance with all Federal and state securities laws.

          (d)  Other Commitments to Register Securities.  Except as set forth
               ----------------------------------------
herein and in the Investor Rights Agreement dated as of January 17, 1997, the
Company is not, pursuant to the terms of any other agreement currently in
existence, under any obligation to register under the Securities Act any of its
presently outstanding securities or any of its securities which may hereafter be
issued.

          (e)  Exempt Transaction.  Subject to the accuracy of the Holder's
               ------------------
representations in this Section 11 and any filing necessary to obtain a state
securities law exemption, the issuance of Shares upon exercise of this Warrant
will constitute a transaction exempt from (i) the registration requirements of
Section 5 of the Securities Act, in reliance upon Section 4(2) thereof, and (ii)
the qualification requirements of the applicable state securities laws.

                                       11
<PAGE>

          (f)  Compliance with Rule 144.  At the written request of Holder, who
               ------------------------
proposes to sell Warrant Shares issuable upon the exercise of this Warrant in
compliance with Rule 144 promulgated by the Securities and Exchange Commission,
the Company shall furnish to Holder, within ten (10) days after receipt of such
request, a written statement confirming the Company's compliance with the filing
requirements of the Securities and Exchange Commission as set forth in such
Rule, as such Rule may be amended from time to time.

     12.  Representations and Warranties by the Holder.  Holder represents and
          --------------------------------------------
warrants to the Company as follows:

          (a)  This Warrant is being acquired for its own account, for
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Act and the
Holder has no present intention of selling or engaging in any public
distribution thereof pursuant to a registration or exemption.

          (b)  Holder understands that the Warrant and the Shares have not been
registered under the Act by reason of their issuance in a transaction exempt
from the registration and prospectus delivery requirements of the Act pursuant
to Section 4(2) thereof, and that they must be held by Holder indefinitely, and
that Holder must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Act or is exempted from such registration.  The Holder further understands that
the Shares have not been qualified under the California Securities Law of 1968
(the "California Law") by reason of their issuance in a transaction exempt from
the qualification requirements of the California Law pursuant to Section
25102(f) thereof, which exemption depends upon, among other things, the bona
fide nature of the Holder's investment intent expressed above.

          (c)  The Holder has such knowledge and experience in financial and
business matters that it is capable of evaluating the merits and risks of the
purchase of this Warrant and the Shares purchasable pursuant to the terms of
this Warrant and of protecting its interests in connection therewith.

          (d)  The Holder is able to bear the economic risk of the purchase of
the Shares pursuant to the terms of this Warrant.

     13.  Rights of Stockholders.  Nothing contained herein be construed to
          ----------------------
confer upon Holder any of the rights of a stockholder of the Company or any
right to vote for the election of directors or upon any matter submitted to
stockholders at any meeting thereof, or to give or withhold consent to any
corporate action (whether upon any recapitalization, issuance of stock,
reclassification of stock, change of par value, consolidation, merger,
conveyance, or otherwise) or to receive notice of meetings, or to receive
dividends or subscription rights or otherwise until the Warrant shall have been
exercised and the Shares purchasable upon the exercise hereof shall have become
deliverable, as provided herein.

                                       12
<PAGE>

     14.  Expiration of Warrant.
          ---------------------

          (a)  This Warrant shall expire and shall no longer be exercisable as
of (i) 5:00 p.m., California local time, on November ___, 2004; (ii) three (3)
years after the Company's Initial Public Offering; or (iii) a consolidation or
merger of the Company with or into another corporation (other than a
consolidation or merger with another corporation in which the Company's
stockholders immediately preceding such consolidation or merger own at least 50%
of the voting securities of the successor entity following such consolidation or
merger and which does not result in any reclassification of the Shares issuable
upon exercise of this Warrant); or (iv) a sale of all or substantially all of
the assets of the Company; provided, however, that Section 4-9 shall survive the
expiration of this Warrant and shall terminate as set forth in subsection (b)
below.

          (b)  Termination of the Company's Obligations.
               ----------------------------------------

               (i)    Notwithstanding any contrary provision of Section 4, the
Company shall not be required to effect any registrations under the 1933 Act or
under any state securities laws on behalf of Holder if the Company's Common
Stock is publicly traded on a national exchange (including NASDAQ) and in the
opinion of counsel for the Company, the offering or transfer by Holder in the
manner proposed (including, without limitation, the number of shares proposed to
be offered or transferred, the time of sale, and the method of offering or
transfer) is exempt from the registration requirements of the 1933 Act and the
securities laws of applicable states and the Company consents to such transfer,
if required. Sections 5 and 7 shall also terminate upon the date that the Shares
are publicly traded as set forth above.

               (ii)   The Company's obligations to deliver reports and other
information under Section 6 will terminate upon the closing of a sale of shares
of the Company's capital stock pursuant to the Company's Initial Public
Offering.

               (iii)  Section 8 shall terminate 180 days after the Company's
Initial Public Offering.

     15.  Miscellaneous.
          -------------

          (a)  This Warrant is being delivered in the State of California and
shall be construed and enforced in accordance with and governed by the laws of
such State.  The parties expressly stipulate that any litigation under this
Warrant shall be brought in the State courts of the Counties of Santa Clara or
San Francisco, California and in the United States District Court for the
Northern District of California.  The parties agree to submit to the
jurisdiction and venue of those courts.

          (b)  The headings in this Warrant are for purposes of reference only,
and shall not limit or otherwise affect any of the terms hereof.

          (c)  The terms of this Warrant shall be binding upon and shall inure
to the benefit of any successors in interest of the Company or the Holder. This
Warrant and all rights hereunder are

                                       13
<PAGE>

not assignable or transferable by Company or Holder, except for such permitted
transfers to successors in interest and in accordance with Section 7 herein, and
any attempt to assign or transfer the rights hereunder shall be void and of no
further effect. Upon a sale or transfer of the Shares pursuant to Section 7
herein, the rights granted to Holder in Sections 4, 5, and 6 herein shall
immediately terminate with respect to the transferred Shares unless Holder
obtains the written consent of Company to transfer those rights, which consent
shall not be unreasonably withheld.

          (d)  This Warrant and the other documents delivered pursuant hereto
constitute the full and entire understanding and agreement between the parties
with regard to the subjects hereof and thereof.

          (e)  The Company shall not, by amendment of its Amended and Restated
Articles of Incorporation, or through any other means, directly or indirectly,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant and shall at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the holder of this Warrant against
impairment.

          (f)  Upon receipt of evidence reasonably satisfactory to the Company
of the loss, theft, destruction or mutilation of this Warrant and, in the case
of any such loss, theft or destruction, upon delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of any
such mutilation, upon surrender and cancellation of such Warrant, the Company at
its expense will execute and deliver to the holder of record, in lieu thereof, a
new Warrant of like date and tenor.

          (g)  This Warrant and any provision hereof may be amended, waived or
terminated only by an instrument in writing signed by the Company and Holder.

                                       14

     IN WITNESS WHEREOF, the Company has caused this Warrant to be signed by its
duly authorized officer.

     Issued this _______ day of November, 1997.

                      INVESTMENT REPRESENTATION STATEMENT

PURCHASER   :  COMDISCO, INC.

COMPANY     :  AGORA DIGITAL CORPORATION

SECURITY    :  COMMON STOCK ISSUED UPON EXERCISE OF THE COMMON STOCK PURCHASE
               WARRANT ISSUED ON NOVEMBER _____, 1997

AMOUNT      :  _______________ SHARES

DATE        :  ___________________, ______

In connection with the purchase of the above-listed Securities, I, the
Purchaser, represent to the Company the following:

     (a)  I am aware of the Company's business affairs and financial condition,
and have acquired sufficient information about the Company to reach an informed
and knowledgeable decision to acquire the Securities.  I am purchasing these
Securities for my own account for investment purposes only and not with a view
to, or for the resale in connection with, any "distribution" thereof for
purposes of the Securities Act of 1933, as amended (the "Securities Act") except
pursuant to a registration of exemption.

     (b)  I understand that the Securities have not been registered under the
Securities Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of my investment intent
as expressed herein.  In this connection, I understand that, in the view of the
Securities and Exchange Commission (the "SEC"), the statutory basis for such
exemption may be unavailable if my representation was predicated solely upon a
present intention to hold these Securities for the minimum capital gains period
specified under tax statutes, for a deferred sale, for or until an increase or
decrease in the market price of the Securities, or for a period of one year or
any other fixed period in the future.

     (c)  I further understand that the Securities must be held indefinitely
unless subsequently registered under the Securities Act or unless an exemption
from registration is otherwise available.  Moreover, I understand that the
Company is under no obligation to register the Securities.  In addition, I
understand that the certificate evidencing the Securities will be imprinted with
a legend which prohibits the transfer of the Securities unless they are
registered or such registration is not required in the opinion of counsel for
the Company.

     (d)  I am familiar with the provisions of Rule 144, promulgated under the
Securities Act, which, in substance, permits limited public resale of
"restricted securities" acquired, directly or
<PAGE>

indirectly, from the issuer thereof, in a non-public offering subject to the
satisfaction of certain conditions.

     The Securities may be resold in certain limited circumstances subject to
the provisions of Rule 144, which requires among other things: (1) the
availability of certain public information about the Company, (2) the resale
occurring not less than one year, and in some circumstances two years, after the
party has held, within the meaning of Rule 144, the securities to be sold; and,
in the case of an affiliate, or of a non-affiliate who has held the securities
less than two years, and in some circumstances three years, (3) the sale being
made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker (as said term is defined under the
Securities Exchange Act of 1934) and the amount of securities being sold during
any three month period not exceeding the specified limitations stated therein,
if applicable.

     (e)  I agree, in connection with the Company's initial underwritten public
offering of the Company's securities, (1) not to sell, make 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 me (other than those shares included in the
registration) without the prior written consent of the Company or the
underwriters managing such initial underwritten public offering of the Company's
securities for one hundred eighty (180) days from the effective date of such
registration, and (2) I further agree to execute any agreement reflecting (1)
above as may be requested by the underwriters at the time of the public
offering; provided however that the officers and directors of the Company who
          -------- -------
own the stock of the Company also agree to such restrictions.

     (f)  I further understand that in the event all of the applicable
requirements of Rule 144 are not satisfied, registration under the Securities
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive, the
Staff of the SEC has expressed its opinion that persons proposing to sell
private placement securities other than in a registered offering and otherwise
than pursuant to Rule 144 will have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or
sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk.

                   SERIES B PREFERRED STOCK PURCHASE WARRANT

THIS WARRANT HAS BEEN, AND THE SHARES OF SERIES B PREFERRED STOCK WHICH MAY BE
PURCHASED PURSUANT TO THE EXERCISE OF THIS WARRANT (THE "SHARES"), WILL BE
ACQUIRED SOLELY FOR INVESTMENT AND NOT WITH A VIEW TO, OR FOR RESALE IN
CONNECTION WITH, ANY DISTRIBUTION THEREOF. NEITHER THIS WARRANT NOR THE SHARES
OF SERIES B PREFERRED STOCK ISSUABLE HEREUNDER OR ANY SHARES INTO WHICH SUCH
SHARES ARE CONVERTIBLE, (TOGETHER, THE "SECURITIES") HAVE BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR ANY STATE SECURITIES
LAWS. SUCH SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED

COMPANY AND ITS COUNSEL THAT SUCH DISPOSITION IS EXEMPT FROM THE REGISTRATION
AND PROSPECTUS DELIVERY REQUIREMENTS OF THE ACT AND OF ANY APPLICABLE STATE
SECURITIES LAWS.

                                                       Void after March 11, 2008

                               2BRIDGE SOFTWARE

            WARRANT TO PURCHASE SHARES OF SERIES B PREFERRED STOCK

                                 ____________

     THIS CERTIFIES THAT, for value received, Comdisco, Inc. (the "Holder") is
entitled to subscribe for and purchase from 2Bridge Software, a California
corporation (the "Company"), shares of the Company's fully paid and
nonassessable Series B Preferred Stock (the "Shares"), in the amounts and at the
price per share set forth in Section 1 below (as adjusted pursuant to Section 4
hereof), subject to the provisions and upon the terms and conditions hereinafter
set forth.

     This Warrant is subject to the following terms and conditions:

     1.   Number and Price of Shares.
          --------------------------

          (a)  The Holder shall have the right to purchase a number of Shares
equal to eighty-one thousand two hundred fifty dollars ($81,250), or 6.5% of the
$1,250,000 principal amount of the Note by and between the Company and the
Holder, divided by the Exercise Price, as defined in Section 1(b) below.

          (b)  The exercise price per Share ("Exercise Price") shall be equal
to: (i) the price at which the Company sells the Shares in an equity financing
completed on or before July 11, 1998, or (ii) if such a financing is not
completed by July 11, 1998, the average of the price at which the Company sells
the Shares and the original issue price of the Series A Preferred Stock of
$.8718.
<PAGE>

          (c)  An example of this formula is as follows: if the Company
completes a Series B Preferred Stock financing at $1.75 per share, the number
and Exercise Price of the Shares would be:

               (i)    $81,250/ $1.75 = 46,428 Shares, exercisable at $1.75 per
share, if the financing is completed within 120 days of the date of this
Warrant; or

               (ii)   $81,250/ ((1.75+ .8718)/2) = 81,250/ $1.3109 = 61,980
Shares, exercisable at $1.3109 per share, if the financing is completed more
than 120 days after the date of this Warrant.

          (d)  In the event the Company does not complete a round of Preferred
Stock financing within 180 days of the date of this Warrant, this Warrant shall
be exercisable for shares of the Company's Series A Preferred Stock, and all
references to the Shares and the Series B Preferred Stock herein shall mean the
Series A Preferred Stock of the Company. The Exercise Price shall be $.8718 for
any Series A Preferred Stock issued hereunder.

     2.   Method of Exercise; Payment.
          ---------------------------

          (a)  Cash Exercise.  The purchase rights represented by this Warrant
               -------------
may be exercised by the Holder, in whole or in part, from time to time by: (i)
the surrender of this Warrant (with the notice of exercise form (the "Notice of
Exercise") attached hereto as Exhibit A duly executed) at the principal office
                              ---------
of the Company; (ii) the execution of a Series B Preferred Stock Purchase
Agreement and all exhibits thereto, including without limitation an Amended and
Restated Investor Rights Agreement, Voting Agreement, and Co-Sale Agreement
(collectively, the "Series B Transaction Documents"); and (iii) by the payment
to the Company of an amount equal to the Exercise Price multiplied by the number
of the Shares being purchased, which amount may be paid, at the election of the
Holder, by wire transfer or certified check payable to the order of the Company.
The person or persons in whose name(s) any certificate(s) representing Shares
shall be issuable upon exercise of this Warrant shall be deemed to have become
the holder(s) of record of, and shall be treated for all purposes as the record
holder(s) of, the Shares represented thereby (and such Shares shall be deemed to
have been issued) immediately prior to the close of business on the date or
dates upon which this Warrant is exercised.

          (b)  Net Issue Exercise.  In lieu of exercising this Warrant pursuant
               ------------------
to Section 2(a) hereof, the Holder may elect to receive a number of Shares equal
to the value (as determined below) of this Warrant (or the portion thereof being
canceled) by surrender of this Warrant and the fully executed Series B
Transaction Documents at the principal office of the Company, together with the
Notice of Exercise in which alternative No. 1 is initiated by the Holder. In
such event, the Company shall issue to the Holder a number of Shares computed
using the following formula:

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

                                       2
<PAGE>

Where X   =    the number of Shares to be issued to the Holder.

      Y   =    the number of Shares subject to this warrant.

      A   =    the fair market value of one share of the Company's Series B
               Preferred Stock.

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

          (c)  Fair Market Value.  For purposes of this Section 2, the fair
               -----------------
market value of the Company's Series B Preferred Stock shall mean:

               (i)    The average of the closing bid and asked prices of the
Company's Common Stock quoted in the Over-The-Counter Market Summary or the
closing price quoted on any exchange on which the Common Stock is listed,
whichever is applicable, as published in the Western Edition of The Wall Street
                                                                ---------------
Journal for the ten trading days prior to the date of determination of fair
- -------
market value multiplied by the number of shares of Common Stock into which each
share of Series B Preferred Stock is convertible;

               (ii)   If the Company's Common Stock is not traded Over-The-
Counter or on an exchange, the fair market value of the Series B Preferred Stock
per share shall be the price per share which the Company could obtain from a
willing buyer for shares sold by the Company from authorized but unissued shares
of Series B Preferred Stock as such price shall be agreed by the parties hereto,
or if agreement cannot be reached within five (5) business days of delivery of
the notice pursuant to Section 2(b) hereof, as shall be determined by a panel of
appraisers. One appraiser shall be selected by the Holder, one appraiser shall
be chosen by the Company and the third appraiser shall be chosen by the first
two appraisers. If the appraisers cannot reach agreement as to the fair market
value on the foregoing basis on or before the thirtieth (30th) day following the
Holder's notice of election pursuant to Section 2(b), then each appraiser shall
deliver its appraisal and the appraisal which is neither the highest nor the
lowest shall be the fair market value of a share of Series B Preferred Stock. In
the event that the Holder fails to choose an appraiser or the three appraisers
fail to deliver an appraisal on or before the thirtieth (30th) day after such
notice, the appraisal of the appraiser selected by the Company shall control and
shall be fair market value for the purposes of this Warrant. The cost of the
appraiser selected by each party shall be borne by that party and the cost of
the third appraiser shall be borne one-half (1/2) by each party. Appraisers
selected under this Section 2(c) must be unaffiliated with the Holder and the
Company and must have reasonable professional qualifications for the appraisal.

          (d)  Stock Certificates.  In the event of any exercise of the rights
               ------------------
represented by this Warrant, certificates for the Shares so purchased shall be
delivered to the Holder within a reasonable time and, unless this Warrant has
been fully exercised or has expired, a new Warrant representing the Shares with
respect to which this Warrant shall not have been exercised shall also be issued
to the Holder within such time.

                                       3
<PAGE>

          (e)  Condition of Exercise  Unless exercised pursuant to an effective
               ---------------------
registration statement under the Act which includes the Shares so exercised, it
shall be a condition to any exercise of this Warrant that the Company shall have
received, at the time of such exercise, a representation in writing from the
Holder in the form attached hereto as Exhibit A-1, that the Shares being issued
                                      -----------
upon exercise are being acquired for investment and not with a view to any sale
or distribution thereof.

     3.   Stock Fully Paid; Reservation of Shares.  All of the Shares issuable
          ---------------------------------------
upon the exercise of the rights represented by this Warrant will, upon issuance
and receipt of the Exercise Price therefor, be fully paid and nonassessable, and
free from all preemptive rights, rights of first refusal or first offer, taxes,
liens and charges with respect to the issuance thereof. During the period within
which the rights represented by this Warrant may be exercised, the Company shall
at all times have authorized and reserved for issuance sufficient shares of its
Series B Preferred Stock and Common Stock to provide for the exercise of the
rights represented by this Warrant.

     4.   Adjustment of Exercise Price and Number of Shares.  The number and
          -------------------------------------------------
kind of Shares purchasable upon the exercise of this Warrant and the Exercise
Price therefor shall be subject to adjustment from time to time upon the
occurrence of certain events, as follows:

          (a)  Stock Splits, Dividends and Combinations.  In the event that the
               ----------------------------------------
Company shall at any time subdivide the outstanding shares of Series B Preferred
Stock, or shall issue a stock dividend on its outstanding shares of Series B
Preferred Stock, the number of Shares issuable upon exercise of this Warrant
immediately prior to such subdivision or to the issuance of such stock dividend
shall be proportionately increased, and the Exercise Price shall be
proportionately decreased, and in the event that the Company shall at any time
combine the outstanding shares of Series B Preferred Stock, the number of Shares
issuable upon exercise of this Warrant immediately prior to such combination
shall be proportionately decreased, and the Exercise Price shall be
proportionately increased, effective at the close of business on the date of
such subdivision, stock dividend or combination, as the case may be.

          (b)  Price Adjustments.  If at any time the Company issues or sells
               -----------------
any shares of its Preferred Stock for a consideration per share less than the
then effective Exercise Price, then and in each such case, the Exercise Price
for the Shares will be reduced to a price (calculated to the nearest cent)
determined by multiplying such applicable Exercise Price by a fraction (a) the
numerator of which will be the number of shares of Preferred Stock outstanding
(or so deemed) immediately prior to such issuance or sale plus the number of
shares of Series B Preferred Stock which the aggregate consideration received by
the Company for such issuance or sale would purchase at such applicable Exercise
Price, and (b) the denominator of which will be the number of shares of
Preferred Stock outstanding (or so deemed) immediately after the Preferred Stock
proposed to be issued or sold is issued or sold; provided that such fraction
will in no event be greater than one (1). For purposes of this Section 4(b), the
Shares will be deemed to be outstanding on the date hereof.

                                       4
<PAGE>

          For the purpose of making any adjustment in the Exercise Price as
provided above, the consideration received by the Company for any issuance or
sale of Preferred Stock will be computed:

                    (A)  to the extent it consists of cash, as the amount of
cash received by the Company before deduction of any offering expenses payable
by the Company and any underwriting or similar commissions, compensation, or
concessions paid or allowed by the Company in connection with such issuance or
sale;

                    (B)  to the extent it consists of property other than cash,
at the fair market value of that property as determined in good faith by the
Company's Board of Directors; and

                    (C)  if Preferred Stock is issued or sold together with
other stock or securities or other assets of the Company for a consideration
which covers both, as the portion of the consideration so received that may be
reasonably determined in good faith by the Board of Directors to be allocable to
such Preferred Stock.

          No adjustment to the Exercise Price pursuant to this Section 4(b)
shall affect the number of Warrants to be issued pursuant to Section 1(a)
herein.

          (c)  Recapitalizations.  If at any time or from time to time there
               -----------------
shall be a recapitalization of the Series B Preferred Stock (other than a
subdivision, combination or merger or sale of assets transaction provided for
elsewhere in this Section 4), provision shall be made so that the Holder of this
Warrant will thereafter be entitled to receive upon exercise of this Warrant the
number of shares of stock or other securities or property of the Company to
which a Holder of Series B Preferred Stock would have been entitled on such
recapitalization. In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 4 with respect to the rights of
the Holder of this Warrant after the recapitalization to the end that the
provisions of this Section 4 (including adjustment of the Exercise Price then in
effect and the number of shares issuable upon exercise of this Warrant) shall be
applicable after that event in as nearly an equivalent manner as may be
practicable.

          (d)  Merger.  If at any time there shall be a capital reorganization
               ------
of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation, whether or not the Company is the surviving corporation, other than
as provided for in Section 10(a) herein (a "Merger Event"), then as a part of
such Merger Event, lawful provision shall be made so that the Holder shall
thereafter be entitled to receive, upon exercise of the Warrant, the number of
shares of stock or other securities of the successor corporation resulting from
such Merger Event, equivalent in value to that which would have been issuable if
Holder had exercised this Warrant immediately prior to the Merger Event. In any
such case, appropriate adjustment (as determined in good faith by the Company's
Board of Directors) shall be made in the application of the provisions of this
Warrant with respect to the rights and interest of the Holder after the Merger

                                       5
<PAGE>

Event to the end that the provisions of this Warrant (including adjustments of
the Exercise Price and number of Shares purchasable) shall be applicable to the
greatest extent possible.

          (e)  Notices.  Upon any adjustment of the Exercise Price and any
               -------
increase or decrease in the number of Shares purchasable upon the exercise of
this Warrant in accordance with Section 3 hereof, then, and in each such case,
the Company, within thirty (30) days thereafter, shall give written notice
thereof to the Holder at the address of such Holder as shown on the books of the
Company which notice shall state the Exercise Price as adjusted and, if
applicable, the increased or decreased number of Shares purchasable upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation of each. Any written notice by the Company required or permitted
hereunder shall be given by hand delivery or first class mail, postage prepaid,
addressed to the Holder at the address shown on the books of the Company for the
Holder.

     5.   Restrictions on Transfer.
          ------------------------

          (a)  Holder agrees not to make any disposition of all or any portion
of the Shares or the Warrant unless and until:

               (i)    There is then in effect a registration statement under the
1933 Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

               (ii)   Holder shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition, and the transferee has
agreed in writing to be bound by this Section 5. If reasonably requested by the
Company, Holder shall furnish the Company with an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will not require registration
of such shares under the 1933 Act. Notwithstanding the foregoing, the
restrictions imposed upon the transferability of any of the Shares or rights to
acquire Shares do not apply to transfers from the beneficial owner of any of the
aforementioned securities to its nominee or from such nominee to its beneficial
owners, and shall terminate as to any particular Shares when a letter shall have
been issued to Holder at its request by the staff of the Securities and Exchange
Commission or a ruling shall have been issued to the Holder at its request by
such Commission stating that no action shall be recommended by such staff or
taken by such Commission, as the case may be, if such security is transferred
without registration under the 1933 Act in accordance with the conditions set
forth in such letter or ruling and such letter or ruling specifies that no
subsequent restrictions on transfer are required. It is agreed that the Company
will not require opinions of counsel for transactions made pursuant to Rule 144
except in unusual circumstances.

          (b)  Notwithstanding the above, the Shares shall also be subject to
all restrictions on transfer set forth in the Series B Transaction Documents,
including without limitation a 180 day market standoff period upon the Company's
initial public offering.

                                       6
<PAGE>

     6.   Fractional Shares.  No fractional shares of Common Stock will be
          -----------------
issued in connection with any exercise hereunder, but in lieu of such fractional
shares the Company shall make a cash payment therefor upon the basis of the
Exercise Price then in effect.

     7.   Representations and Warranties by the Company.
          ---------------------------------------------

          (a)  Due Authority.  The execution and delivery by the Company of this
               -------------
Warrant and the performance of all obligations of the Company hereunder,
including the issuance to Holder of the right to acquire Shares, have been duly
authorized by all necessary corporate action on the part of the Company. This
Warrant is consistent with the Company's Amended and Restated Articles of
Incorporation, and does not contravene any law or governmental rule, regulation
or order applicable to it, and does not and will not contravene any provision
of, or constitute a default under, any indenture, mortgage, contract or other
instrument to which it is a party or by which it is bound. This Warrant
constitutes a legal, valid and binding agreement of the Company, enforceable in
accordance with its respective terms.

          (b)  Consents and Approvals.  No consent or approval of, giving of
               ----------------------
notice to, registration with, or taking of any other action in respect of any
state, Federal or other governmental authority or agency is required with
respect to the execution, delivery and performance by the Company of its
obligations under this Warrant, except for the filing of notices pursuant to
Regulation D under the 1933 Act and any filing required by applicable state
securities law, which filings shall be made by the time required thereby.

          (c)  Holder's Additional Rights.  The Series B Preferred Stock shall
               --------------------------
have anti-dilution rights, registration rights, and information rights
substantially similar to those rights given to holders of the Company's Series A
Preferred Stock, which rights shall be set forth in the Series B Transaction
Documents.

          (d)  Other Commitments to Register Securities.  Except as set forth
               ----------------------------------------
herein and in the Investor Rights Agreement dated as of January 17, 1997 and the
Warrants issued to Holder as of November __, 1997 and the date hereof, the
Company is not, pursuant to the terms of any other agreement currently in
existence, under any obligation to register under the Securities Act any of its
presently outstanding securities or any of its securities which may hereafter be
issued.

          (e)  Exempt Transaction.  Subject to the accuracy of the Holder's
               ------------------
representations in this Section 11 and any filing necessary to obtain a state
securities law exemption, the issuance of Shares upon exercise of this Warrant
will constitute a transaction exempt from (i) the registration requirements of
Section 5 of the Securities Act, and (ii) the qualification requirements of the
applicable state securities laws.

          (f)  Compliance with Rule 144.  At the written request of Holder, who
               ------------------------
proposes to sell Warrant Shares issuable upon the exercise of this Warrant in
compliance with Rule 144 promulgated by the Securities and Exchange Commission,
the Company shall furnish to Holder, within ten (10) days after receipt of such
request, a written statement confirming the Company's

                                       7
<PAGE>

compliance with the filing requirements of the Securities and Exchange
Commission as set forth in such Rule, as such Rule may be amended from time to
time.

          (g)  The Company agrees to take all actions necessary to issue the
Series A Preferred Stock described in Section 1(d) herein if the Company has not
completed a Preferred Stock financing within 180 days of the date of this
Warrant, including without limitation obtaining all shareholder and director
consents, amending the Company's Articles of Incorporation, and amending any
Series A Preferred Stock transaction documents required to effect such issuance
to Holder.

     8.   Representations and Warranties by the Holder.  Holder represents and
          --------------------------------------------
warrants to the Company as follows:

          (a)  Holder understands that no Series B Preferred Stock has been
authorized or issued as of the date hereof, and the Company can make no
assurances that such security will ever exist.

          (b)  This Warrant is being acquired for Holder's own account, for
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Act, and the
Holder has no present intention of selling or engaging in any public
distribution thereof pursuant to a registration or exemption.

          (c)  Holder understands that the Warrant and the Shares have not been
registered under the Act by reason of their issuance in a transaction exempt
from the registration and prospectus delivery requirements of the Act pursuant
to Section 4(2) thereof, and that they must be held by Holder indefinitely, and
that Holder must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Act or is exempted from such registration. The Holder further understands that
the Shares have not been qualified under the California Securities Law of 1968
(the "California Law") by reason of their issuance in a transaction exempt from
the qualification requirements of the California Law pursuant to Section
25102(f) thereof, which exemption depends upon, among other things, the bona
fide nature of the Holder's investment intent expressed above.

          (d)  The Holder has such knowledge and experience in financial and
business matters that it is capable of evaluating the merits and risks of the
purchase of this Warrant and the Shares purchasable pursuant to the terms of
this Warrant and of protecting its interests in connection therewith.

          (e)  The Holder is able to bear the economic risk of the purchase of
the Shares pursuant to the terms of this Warrant.

     9.   Rights of Stockholders.  Nothing contained herein shall confer upon
          ----------------------
Holder any of the rights of a stockholder of the Company or any right to vote
for the election of directors or upon any matter submitted to stockholders at
any meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of
stock,

                                       8
<PAGE>

change of par value, consolidation, merger, conveyance, or otherwise) or to
receive notice of meetings, or to receive dividends or subscription rights or
otherwise until the Warrant shall have been exercised and the Shares purchasable
upon the exercise hereof shall have become deliverable, as provided herein.

     10.  Expiration of Warrant.
          ---------------------

          (a)  This Warrant shall expire and shall no longer be exercisable as
of the earlier of:

                (i)   5:00 p.m., California local time, on March 11, 2008;

                (ii)  five (5) years after the Company's initial public offering
under the Securities Act of 1933, as amended;

                (iii) the automatic conversion of the Series B Preferred Stock
of the Company into Common Stock of the Company, according to the terms of the
Series B Transaction Documents, provided that Company provides Holder with at
least thirty (30) days notice of such automatic conversion and that it gives
Holder an option in Holder's sole discretion to either exercise the Warrant or
cause Company to replace the Warrant with a Warrant to Purchase Common Stock on
substantially the same terms as those set forth herein;

                (iv)  a consolidation or merger of the Company with or into
another corporation (other than a consolidation or merger with another
corporation in which the Company's stockholders immediately preceding such
consolidation or merger own at least 50% of the voting securities of the
successor entity following such consolidation or merger and which does not
result in any reclassification of the Shares issuable upon exercise of this
Warrant); or

                (v)   a sale of all or substantially all of the assets of the
Company.

     11.  Miscellaneous.
          -------------

          (a)  This Warrant is being delivered in the State of California and
shall be construed and enforced in accordance with and governed by the laws of
such State. The parties expressly stipulate that any litigation under this
Warrant shall be brought in the State courts of the Counties of Santa Clara or
San Francisco, California and in the United States District Court for the
Northern District of California. The parties agree to submit to the jurisdiction
and venue of those courts. Notwithstanding the foregoing, any claim or dispute
involving questions of usury law as it applies to the Warrant shall be governed
by the laws of Illinois.

          (b)  The headings in this Warrant are for purposes of reference only,
and shall not limit or otherwise affect any of the terms hereof.

                                       9
<PAGE>

          (c)  The terms of this Warrant shall be binding upon and shall inure
to the benefit of any successors in interest of the Company or the Holder. This
Warrant and all rights hereunder are not assignable or transferable by Company
or Holder, except for such permitted transfers to successors in interest and in
accordance with Section 5 herein, and any attempt to assign or transfer the
rights hereunder shall be void and of no further effect.

          (d)  This Warrant and the other documents delivered pursuant hereto,
including without limitation the Series B Transaction Documents, constitute the
full and entire understanding and agreement between the parties with regard to
the subjects hereof and thereof.

          (e)  The Company shall not, by amendment of its Amended and Restated
Articles of Incorporation, or through any other means, directly or indirectly,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant and shall at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the holder of this Warrant against
impairment.

          (f)  Upon receipt of evidence reasonably satisfactory to the Company
of the loss, theft, destruction or mutilation of this Warrant and, in the case
of any such loss, theft or destruction, upon delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of any
such mutilation, upon surrender and cancellation of such Warrant, the Company at
its expense will execute and deliver to the holder of record, in lieu thereof, a
new Warrant of like date and tenor.

          (g)  This Warrant and any provision hereof may be amended, waived or
terminated only by an instrument in writing signed by the Company and Holder.

     IN WITNESS WHEREOF, the Company has caused this Warrant to be signed by its
duly authorized officer.

     Issued this 11th day of March, 1998.

In connection with the purchase of the above-listed Securities, I, the
Purchaser, represent to the Company the following:

     (a)  I am aware of the Company's business affairs and financial condition,
and have acquired sufficient information about the Company to reach an informed
and knowledgeable decision to acquire the Securities. I am purchasing these
Securities for my own account for investment purposes only and not with a view
to, or for the resale in connection with, any "distribution" thereof for
purposes of the Securities Act of 1933, as amended (the "Securities Act") except
pursuant to a registration of exemption.

     (b)  I understand that the Securities have not been registered under the
Securities Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of my investment intent
as expressed herein. In this connection, I understand that, in the view of the
Securities and Exchange Commission (the "SEC"), the statutory basis for such
exemption may be unavailable if my representation was predicated solely upon a
present intention to hold these Securities for the minimum capital gains period
specified under tax statutes, for a deferred sale, for or until an increase or
decrease in the market price of the Securities, or for a period of one year or
any other fixed period in the future.

     (c)  I further understand that the Securities must be held indefinitely
unless subsequently registered under the Securities Act or unless an exemption
from registration is otherwise available. Moreover, I understand that the
Company is under no obligation to register the Securities. In addition, I
understand that the certificate evidencing the Securities will be imprinted with
a legend which prohibits the transfer of the Securities unless they are
registered or such registration is not required in the opinion of counsel for
the Company.

     (d)  I am familiar with the provisions of Rule 144, promulgated under the
Securities Act, which, in substance, permits limited public resale of
"restricted securities" acquired, directly or
<PAGE>

indirectly, from the issuer thereof, in a non-public offering subject to the
satisfaction of certain conditions.

     The Securities may be resold in certain limited circumstances subject to
the provisions of Rule 144, which requires among other things: (1) the
availability of certain public information about the Company, (2) the resale
occurring not less than one year, and in some circumstances two years, after the
party has held, within the meaning of Rule 144, the securities to be sold; and,
in the case of an affiliate, or of a non-affiliate who has held the securities
less than two years, and in some circumstances three years, (3) the sale being
made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker (as said term is defined under the
Securities Exchange Act of 1934) and the amount of securities being sold during
any three month period not exceeding the specified limitations stated therein,
if applicable.

     (e)  I agree, in connection with the Company's initial underwritten public
offering of the Company's securities, (1) not to sell, make 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 me (other than those shares included in the
registration) without the prior written consent of the Company or the
underwriters managing such initial underwritten public offering of the Company's
securities for one hundred eighty (180) days from the effective date of such
registration, and (2) I further agree to execute any agreement reflecting (1)
above as may be requested by the underwriters at the time of the public
offering; provided however that the officers and directors of the Company who
          -------- -------
own the stock of the Company also agree to such restrictions.

     (f)  I further understand that in the event all of the applicable
requirements of Rule 144 are not satisfied, registration under the Securities
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive, the
Staff of the SEC has expressed its opinion that persons proposing to sell
private placement securities other than in a registered offering and otherwise
than pursuant to Rule 144 will have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or
sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk.

ACQUIRED SOLELY FOR INVESTMENT AND NOT WITH A VIEW TO, OR FOR RESALE IN
CONNECTION WITH, ANY DISTRIBUTION THEREOF.  NEITHER THIS WARRANT NOR THE SHARES

No. 6
                                                       Void after March 11, 2008

                               2BRIDGE SOFTWARE

            WARRANT TO PURCHASE SHARES OF SERIES B PREFERRED STOCK
                                 _____________

     THIS CERTIFIES THAT, for value received, Comdisco, Inc. (the "Holder") is
entitled to subscribe for and purchase from 2Bridge Software, a California
corporation (the "Company"), shares of the Company's fully paid and
nonassessable Series B Preferred Stock (the "Shares"), in the amounts and at the
price per share set forth in Section 1 below (as adjusted pursuant to Section 4
hereof), subject to the provisions and upon the terms and conditions hereinafter
set forth.

     This Warrant is subject to the following terms and conditions:

     1.   Number and Price of Shares.
          --------------------------

          (a)  The Holder shall have the right to purchase a number of Shares
equal to sixty-two thousand five hundred dollars ($62,500), or 5% of the
$1,250,000 principal amount of the Note by and between the Company and the
Holder, divided by the Exercise Price, as defined in Section 1(b) below.

          (b)  The exercise price per Share ("Exercise Price") shall be equal
to: (i) the price at which the Company sells the Shares in an equity financing
completed on or before July 11, 1998, or (ii) if such a financing is not
completed by July 11, 1998, the average of the price at which the Company sells
the Shares and the original issue price of the Series A Preferred Stock of
$.8718.
<PAGE>

          (c)  An example of this formula is as follows:  if the Company
completes a Series B Preferred Stock financing at $1.75 per share, the number
and Exercise Price of the Shares would be:

               (i)   $62,500/ $1.75 = 35,714 Shares, exercisable at $1.75 per
share, if the financing is completed within 120 days of the date of this
Warrant; or

               (ii)  $62,500/ ((1.75+ .8718)/2) = 62,500/ $1.3109 = 47,677
Shares, exercisable at $1.3109 per share, if the financing is completed more
than 120 days after the date of this Warrant.

          (d)  In the event the Company does not complete a round of Preferred
Stock financing within 180 days of the date of this Warrant, this Warrant shall
be exercisable for shares of the Company's Series A Preferred Stock, and all
references to the Shares and the Series B Preferred Stock herein shall mean the
Series A Preferred Stock of the Company.  The Exercise Price shall be $.8718 for
any Series A Preferred Stock issued hereunder.

     2.   Method of Exercise; Payment.
          ---------------------------

          (a)  Cash Exercise.  The purchase rights represented by this Warrant
               -------------
may be exercised by the Holder, in whole or in part, from time to time by: (i)
the surrender of this Warrant (with the notice of exercise form (the "Notice of
Exercise") attached hereto as Exhibit A duly executed) at the principal office
                              ---------
of the Company; (ii) the execution of a Series B Preferred Stock Purchase
Agreement and all exhibits thereto, including without limitation an Amended and
Restated Investor Rights Agreement, Voting Agreement, and Co-Sale Agreement
(collectively, the "Series B Transaction Documents"); and (iii)  by the payment
to the Company of an amount equal to the Exercise Price multiplied by the number
of the Shares being purchased, which amount may be paid, at the election of the
Holder, by wire transfer or certified check payable to the order of the Company.
The person or persons in whose name(s) any certificate(s) representing Shares
shall be issuable upon exercise of this Warrant shall be deemed to have become
the holder(s) of record of, and shall be treated for all purposes as the record
holder(s) of, the Shares represented thereby (and such Shares shall be deemed to
have been issued) immediately prior to the close of business on the date or
dates upon which this Warrant is exercised.

          (b)  Net Issue Exercise.  In lieu of exercising this Warrant pursuant
               ------------------
to Section 2(a) hereof, the Holder may elect to receive a number of Shares equal
to the value (as determined below) of this Warrant (or the portion thereof being
canceled) by surrender of this Warrant and the fully executed Series B
Transaction Documents at the principal office of the Company, together with the
Notice of Exercise in which alternative No. 1 is initiated by the Holder.  In
such event, the Company shall issue to the Holder a number of Shares computed
using the following formula:


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

                                       2
<PAGE>

Where X   =    the number of Shares to be issued to the Holder.

      Y   =    the number of Shares subject to this warrant.

      A   =    the fair market value of one share of the Company's Series B
               Preferred Stock.

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

          (c)  Fair Market Value.  For purposes of this Section 2, the fair
               -----------------
market value of the Company's Series B Preferred Stock shall mean:

               (i)   The average of the closing bid and asked prices of the
Company's Common Stock quoted in the Over-The-Counter Market Summary or the
closing price quoted on any exchange on which the Common Stock is listed,
whichever is applicable, as published in the Western Edition of The Wall Street
                                                                ---------------
Journal for the ten trading days prior to the date of determination of fair
- -------
market value multiplied by the number of shares of Common Stock into which each
share of Series B Preferred Stock is convertible;

               (ii)  If the Company's Common Stock is not traded Over-The-
Counter or on an exchange, the fair market value of the Series B Preferred Stock
per share shall be the price per share which the Company could obtain from a
willing buyer for shares sold by the Company from authorized but unissued shares
of Series B Preferred Stock as such price shall be agreed by the parties hereto,
or if agreement cannot be reached within five (5) business days of delivery of
the notice pursuant to Section 2(b) hereof, as shall be determined by a panel of
appraisers. One appraiser shall be selected by the Holder, one appraiser shall
be chosen by the Company and the third appraiser shall be chosen by the first
two appraisers. If the appraisers cannot reach agreement as to the fair market
value on the foregoing basis on or before the thirtieth (30th) day following the
Holder's notice of election pursuant to Section 2(b), then each appraiser shall
deliver its appraisal and the appraisal which is neither the highest nor the
lowest shall be the fair market value of a share of Series B Preferred Stock. In
the event that the Holder fails to choose an appraiser or the three appraisers
fail to deliver an appraisal on or before the thirtieth (30th) day after such
notice, the appraisal of the appraiser selected by the Company shall control and
shall be fair market value for the purposes of this Warrant. The cost of the
appraiser selected by each party shall be borne by that party and the cost of
the third appraiser shall be borne one-half (1/2) by each party. Appraisers
selected under this Section 2(c) must be unaffiliated with the Holder and the
Company and must have reasonable professional qualifications for the appraisal.

          (d)  Stock Certificates.  In the event of any exercise of the rights
               ------------------
represented by this Warrant, certificates for the Shares so purchased shall be
delivered to the Holder within a reasonable time and, unless this Warrant has
been fully exercised or has expired, a new Warrant representing the Shares with
respect to which this Warrant shall not have been exercised shall also be issued
to the Holder within such time.

                                       3
<PAGE>

          (e)  Condition of Exercise  Unless exercised pursuant to an effective
               ---------------------
registration statement under the Act which includes the Shares so exercised, it
shall be a condition to any exercise of this Warrant that the Company shall have
received, at the time of such exercise, a representation in writing from the
Holder in the form attached hereto as Exhibit A-1, that the Shares being issued
                                      -----------
upon exercise are being acquired for investment and not with a view to any sale
or distribution thereof.

     3.   Stock Fully Paid; Reservation of Shares.  All of the Shares issuable
          ---------------------------------------
upon the exercise of the rights represented by this Warrant will, upon issuance
and receipt of the Exercise Price therefor, be fully paid and nonassessable, and
free from all preemptive rights, rights of first refusal or first offer, taxes,
liens and charges with respect to the issuance thereof.  During the period
within which the rights represented by this Warrant may be exercised, the
Company shall at all times have authorized and reserved for issuance sufficient
shares of its Series B Preferred Stock and Common Stock to provide for the
exercise of the rights represented by this Warrant.

     4.   Adjustment of Exercise Price and Number of Shares.  The number and
          -------------------------------------------------
kind of Shares purchasable upon the exercise of this Warrant and the Exercise
Price therefor shall be subject to adjustment from time to time upon the
occurrence of certain events, as follows:

          (a)  Stock Splits, Dividends and Combinations.  In the event that the
               ----------------------------------------
Company shall at any time subdivide the outstanding shares of Series B Preferred
Stock, or shall issue a stock dividend on its outstanding shares of Series B
Preferred Stock, the number of Shares issuable upon exercise of this Warrant
immediately prior to such subdivision or to the issuance of such stock dividend
shall be proportionately increased, and the Exercise Price shall be
proportionately decreased, and in the event that the Company shall at any time
combine the outstanding shares of Series B Preferred Stock, the number of Shares
issuable upon exercise of this Warrant immediately prior to such combination
shall be proportionately decreased, and the Exercise Price shall be
proportionately increased, effective at the close of business on the date of
such subdivision, stock dividend or combination, as the case may be.

          (b)  Price Adjustments. If at any time the Company issues or sells any
               -----------------
shares of its Preferred Stock for a consideration per share less than the then
effective Exercise Price, then and in each such case, the Exercise Price for the
Shares will be reduced to a price (calculated to the nearest cent) determined by
multiplying such applicable Exercise Price by a fraction (a) the numerator of
which will be the number of shares of Preferred Stock outstanding (or so deemed)
immediately prior to such issuance or sale plus the number of shares of Series B
Preferred Stock which the aggregate consideration received by the Company for
such issuance or sale would purchase at such applicable Exercise Price, and (b)
the denominator of which will be the number of shares of Preferred Stock
outstanding (or so deemed) immediately after the Preferred Stock proposed to be
issued or sold is issued or sold; provided that such fraction will in no event
be greater than one (1).  For purposes of this Section 4(b), the Shares will be
deemed to be outstanding on the date hereof.

                                       4
<PAGE>

          For the purpose of making any adjustment in the Exercise Price as
provided above, the consideration received by the Company for any issuance or
sale of Preferred Stock will be computed:

                    (A)  to the extent it consists of cash, as the amount of
cash received by the Company before deduction of any offering expenses payable
by the Company and any underwriting or similar commissions, compensation, or
concessions paid or allowed by the Company in connection with such issuance or
sale;

                    (B)  to the extent it consists of property other than cash,
at the fair market value of that property as determined in good faith by the
Company's Board of Directors; and

                    (C)  if Preferred Stock is issued or sold together with
other stock or securities or other assets of the Company for a consideration
which covers both, as the portion of the consideration so received that may be
reasonably determined in good faith by the Board of Directors to be allocable to
such Preferred Stock.

          No adjustment to the Exercise Price pursuant to this Section 4(b)
shall affect the number of Warrants to be issued pursuant to Section 1(a)
herein.

          (c)  Recapitalizations.  If at any time or from time to time there
               -----------------
shall be a recapitalization of the Series B Preferred Stock (other than a
subdivision, combination or merger or sale of assets transaction provided for
elsewhere in this Section 4), provision shall be made so that the Holder of this
Warrant will thereafter be entitled to receive upon exercise of this Warrant the
number of shares of stock or other securities or property of the Company to
which a Holder of Series B Preferred Stock would have been entitled on such
recapitalization.  In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 4 with respect to the rights of
the Holder of this Warrant after the recapitalization to the end that the
provisions of this Section 4 (including adjustment of the Exercise Price then in
effect and the number of shares issuable upon exercise of this Warrant) shall be
applicable after that event in as nearly an equivalent manner as may be
practicable.

          (d)  Merger. If at any time there shall be a capital reorganization of
               ------
the shares of the Company's stock (other than a combination, reclassification,
exchange or subdivision of shares otherwise provided for herein), or a merger or
consolidation of the Company with or into another corporation, whether or not
the Company is the surviving corporation, other than as provided for in Section
10(a) herein (a "Merger Event"), then as a part of such Merger Event, lawful
provision shall be made so that the Holder shall thereafter be entitled to
receive, upon exercise of the Warrant, the number of shares of stock or other
securities of the successor corporation resulting from such Merger Event,
equivalent in value to that which would have been issuable if Holder had
exercised this Warrant immediately prior to the Merger Event.  In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interest of the Holder after the Merger

                                       5
<PAGE>

Event to the end that the provisions of this Warrant (including adjustments of
the Exercise Price and number of Shares purchasable) shall be applicable to the
greatest extent possible.

          (e)  Notices.  Upon any adjustment of the Exercise Price and any
               -------
increase or decrease in the number of Shares purchasable upon the exercise of
this Warrant in accordance with Section 3 hereof, then, and in each such case,
the Company, within thirty (30) days thereafter, shall give written notice
thereof to the Holder at the address of such Holder as shown on the books of the
Company which notice shall state the Exercise Price as adjusted and, if
applicable, the increased or decreased number of Shares purchasable upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation of each.   Any written notice by the Company required or permitted
hereunder shall be given by hand delivery or first class mail, postage prepaid,
addressed to the Holder at the address shown on the books of the Company for the
Holder.

     5.   Restrictions on Transfer.
          ------------------------

          (a)  Holder agrees not to make any disposition of all or any portion
of the Shares or the Warrant unless and until:

               (i)   There is then in effect a registration statement under the
1933 Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

               (ii)  Holder shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition, and the transferee has
agreed in writing to be bound by this Section 5. If reasonably requested by the
Company, Holder shall furnish the Company with an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will not require registration
of such shares under the 1933 Act. Notwithstanding the foregoing, the
restrictions imposed upon the transferability of any of the Shares or rights to
acquire Shares do not apply to transfers from the beneficial owner of any of the
aforementioned securities to its nominee or from such nominee to its beneficial
owners, and shall terminate as to any particular Shares when a letter shall have
been issued to Holder at its request by the staff of the Securities and Exchange
Commission or a ruling shall have been issued to the Holder at its request by
such Commission stating that no action shall be recommended by such staff or
taken by such Commission, as the case may be, if such security is transferred
without registration under the 1933 Act in accordance with the conditions set
forth in such letter or ruling and such letter or ruling specifies that no
subsequent restrictions on transfer are required. It is agreed that the Company
will not require opinions of counsel for transactions made pursuant to Rule 144
except in unusual circumstances.

          (b)  Notwithstanding the above, the Shares shall also be subject to
all restrictions on transfer set forth in the Series B Transaction Documents,
including without limitation a 180 day market standoff period upon the Company's
initial public offering.

                                       6
<PAGE>

     6.   Fractional Shares.  No fractional shares of Common Stock will be
          -----------------
issued in connection with any exercise hereunder, but in lieu of such fractional
shares the Company shall make a cash payment therefor upon the basis of the
Exercise Price then in effect.

     7.   Representations and Warranties by the Company.
          ---------------------------------------------

          (a)  Due Authority.  The execution and delivery by the Company of this
               -------------
Warrant and the performance of all obligations of the Company hereunder,
including the issuance to Holder of the right to acquire Shares, have been duly
authorized by all necessary corporate action on the part of the Company.  This
Warrant is consistent with the Company's Amended and Restated Articles of
Incorporation, and does not contravene any law or governmental rule, regulation
or order applicable to it, and does not and will not contravene any provision
of, or constitute a default under, any indenture, mortgage, contract or other
instrument to which it is a party or by which it is bound.  This Warrant
constitutes a legal, valid and binding agreement of the Company, enforceable in
accordance with its respective terms.

          (b)  Consents and Approvals.  No consent or approval of, giving of
               ----------------------
notice to, registration with, or taking of any other action in respect of any
state, Federal or other governmental authority or agency is required with
respect to the execution, delivery and performance by the Company of its
obligations under this Warrant, except for the filing of notices pursuant to
Regulation D under the 1933 Act and any filing required by applicable state
securities law, which filings shall be made by the time required thereby.

          (c)  Holder's Additional Rights.  The Series B Preferred Stock shall
               --------------------------
have anti-dilution rights, registration rights, and information rights
substantially similar to those rights given to holders of the Company's Series A
Preferred Stock, which rights shall be set forth in the Series B Transaction
Documents.

          (d)  Other Commitments to Register Securities.  Except as set forth
               ----------------------------------------
herein and in the Investor Rights Agreement dated as of January 17, 1997 and the
Warrants issued to Holder as of November __, 1997 and the date hereof, the
Company is not, pursuant to the terms of any other agreement currently in
existence, under any obligation to register under the Securities Act any of its
presently outstanding securities or any of its securities which may hereafter be
issued.

          (e)  Exempt Transaction.  Subject to the accuracy of the Holder's
               ------------------
representations in this Section 11 and any filing necessary to obtain a state
securities law exemption, the issuance of Shares upon exercise of this Warrant
will constitute a transaction exempt from (i) the registration requirements of
Section 5 of the Securities Act, and (ii) the qualification requirements of the
applicable state securities laws.

          (f)  Compliance with Rule 144.  At the written request of Holder, who
               ------------------------
proposes to sell Warrant Shares issuable upon the exercise of this Warrant in
compliance with Rule 144 promulgated by the Securities and Exchange Commission,
the Company shall furnish to Holder, within ten (10) days after receipt of such
request, a written statement confirming the Company's

                                       7
<PAGE>

compliance with the filing requirements of the Securities and Exchange
Commission as set forth in such Rule, as such Rule may be amended from time to
time.

          (g)  The Company agrees to take all actions necessary to issue the
Series A Preferred Stock described in Section 1(d) herein if the Company has not
completed a Preferred Stock financing within 180 days of the date of this
Warrant, including without limitation obtaining all shareholder and director
consents, amending the Company's Articles of Incorporation, and amending any
Series A Preferred Stock transaction documents required to effect such issuance
to Holder.

     8.   Representations and Warranties by the Holder.  Holder represents and
          --------------------------------------------
warrants to the Company as follows:

          (a)  Holder understands that no Series B Preferred Stock has been
authorized or issued as of the date hereof, and the Company can make no
assurances that such security will ever exist.

          (b)  This Warrant is being acquired for Holder's own account, for
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Act, and the
Holder has no present intention of selling or engaging in any public
distribution thereof pursuant to a registration or exemption.

          (c)  Holder understands that the Warrant and the Shares have not been
registered under the Act by reason of their issuance in a transaction exempt
from the registration and prospectus delivery requirements of the Act pursuant
to Section 4(2) thereof, and that they must be held by Holder indefinitely, and
that Holder must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Act or is exempted from such registration.  The Holder further understands that
the Shares have not been qualified under the California Securities Law of 1968
(the "California Law") by reason of their issuance in a transaction exempt from
the qualification requirements of the California Law pursuant to Section
25102(f) thereof, which exemption depends upon, among other things, the bona
fide nature of the Holder's investment intent expressed above.

          (d)  The Holder has such knowledge and experience in financial and
business matters that it is capable of evaluating the merits and risks of the
purchase of this Warrant and the Shares purchasable pursuant to the terms of
this Warrant and of protecting its interests in connection therewith.

          (e)  The Holder is able to bear the economic risk of the purchase of
the Shares pursuant to the terms of this Warrant.

     9.   Rights of Stockholders.  Nothing contained herein shall confer upon
          ----------------------
Holder any of the rights of a stockholder of the Company or any right to vote
for the election of directors or upon any matter submitted to stockholders at
any meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of
stock,

                                       8
<PAGE>

change of par value, consolidation, merger, conveyance, or otherwise) or to
receive notice of meetings, or to receive dividends or subscription rights or
otherwise until the Warrant shall have been exercised and the Shares purchasable
upon the exercise hereof shall have become deliverable, as provided herein.

     10.  Expiration of Warrant.
          ---------------------

          (a)  This Warrant shall expire and shall no longer be exercisable as
of the earlier of:

               (i)    5:00 p.m., California local time, on March 11, 2008;

               (ii)   five (5) years after the Company's initial public offering
under the Securities Act of 1933, as amended;

               (iii)  the automatic conversion of the Series B Preferred Stock
of the Company into Common Stock of the Company, according to the terms of the
Series B Transaction Documents, provided that Company provides Holder with at
least thirty (30) days notice of such automatic conversion and that it gives
Holder an option in Holder's sole discretion to either exercise the Warrant or
cause Company to replace the Warrant with a Warrant to Purchase Common Stock on
substantially the same terms as those set forth herein;

               (iv)   a consolidation or merger of the Company with or into
another corporation (other than a consolidation or merger with another
corporation in which the Company's stockholders immediately preceding such
consolidation or merger own at least 50% of the voting securities of the
successor entity following such consolidation or merger and which does not
result in any reclassification of the Shares issuable upon exercise of this
Warrant); or

               (v)    a sale of all or substantially all of the assets of the
Company.

     11.  Miscellaneous.
          -------------

          (a)  This Warrant is being delivered in the State of California and
shall be construed and enforced in accordance with and governed by the laws of
such State.  The parties expressly stipulate that any litigation under this
Warrant shall be brought in the State courts of the Counties of Santa Clara or
San Francisco, California and in the United States District Court for the
Northern District of California.  The parties agree to submit to the
jurisdiction and venue of those courts.  Notwithstanding the foregoing, any
claim or dispute involving questions of usury law as it applies to the Warrant
shall be governed by the laws of Illinois.

          (b)  The headings in this Warrant are for purposes of reference only,
and shall not limit or otherwise affect any of the terms hereof.

                                       9
<PAGE>

          (c)  The terms of this Warrant shall be binding upon and shall inure
to the benefit of any successors in interest of the Company or the Holder. This
Warrant and all rights hereunder are not assignable or transferable by Company
or Holder, except for such permitted transfers to successors in interest and in
accordance with Section 5 herein, and any attempt to assign or transfer the
rights hereunder shall be void and of no further effect.

          (d)  This Warrant and the other documents delivered pursuant hereto,
including without limitation the Series B Transaction Documents, constitute the
full and entire understanding and agreement between the parties with regard to
the subjects hereof and thereof.

          (e)  The Company shall not, by amendment of its Amended and Restated
Articles of Incorporation, or through any other means, directly or indirectly,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant and shall at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the holder of this Warrant against
impairment.

          (f)  Upon receipt of evidence reasonably satisfactory to the Company
of the loss, theft, destruction or mutilation of this Warrant and, in the case
of any such loss, theft or destruction, upon delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of any
such mutilation, upon surrender and cancellation of such Warrant, the Company at
its expense will execute and deliver to the holder of record, in lieu thereof, a
new Warrant of like date and tenor.

          (g)  This Warrant and any provision hereof may be amended, waived or
terminated only by an instrument in writing signed by the Company and Holder.

     IN WITNESS WHEREOF, the Company has caused this Warrant to be signed by its
duly authorized officer.

     Issued this 11th day of March, 1998.

                      INVESTMENT REPRESENTATION STATEMENT

PURCHASER      :    COMDISCO, INC.

COMPANY        :    2BRIDGE SOFTWARE

SECURITY       :    SERIES B PREFERRED STOCK ISSUED UPON EXERCISE OF THE SERIES
                    B PREFERRED STOCK PURCHASE WARRANT ISSUED ON MARCH _____,
                    1998

AMOUNT         :    _______________ SHARES

DATE           :    ___________________, ______

In connection with the purchase of the above-listed Securities, I, the
Purchaser, represent to the Company the following:

     (a)  I am aware of the Company's business affairs and financial condition,
and have acquired sufficient information about the Company to reach an informed
and knowledgeable decision to acquire the Securities.  I am purchasing these
Securities for my own account for investment purposes only and not with a view
to, or for the resale in connection with, any "distribution" thereof for
purposes of the Securities Act of 1933, as amended (the "Securities Act") except
pursuant to a registration of exemption.

     (b)  I understand that the Securities have not been registered under the
Securities Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of my investment intent
as expressed herein.  In this connection, I understand that, in the view of the
Securities and Exchange Commission (the "SEC"), the statutory basis for such
exemption may be unavailable if my representation was predicated solely upon a
present intention to hold these Securities for the minimum capital gains period
specified under tax statutes, for a deferred sale, for or until an increase or
decrease in the market price of the Securities, or for a period of one year or
any other fixed period in the future.

     (c)  I further understand that the Securities must be held indefinitely
unless subsequently registered under the Securities Act or unless an exemption
from registration is otherwise available. Moreover, I understand that the
Company is under no obligation to register the Securities.  In addition, I
understand that the certificate evidencing the Securities will be imprinted with
a legend which prohibits the transfer of the Securities unless they are
registered or such registration is not required in the opinion of counsel for
the Company.

     (d)  I am familiar with the provisions of Rule 144, promulgated under the
Securities Act, which, in substance, permits limited public resale of
"restricted securities" acquired, directly or
<PAGE>

indirectly, from the issuer thereof, in a non-public offering subject to the
satisfaction of certain conditions.

     The Securities may be resold in certain limited circumstances subject to
the provisions of Rule 144, which requires among other things: (1) the
availability of certain public information about the Company, (2) the resale
occurring not less than one year, and in some circumstances two years, after the
party has held, within the meaning of Rule 144, the securities to be sold; and,
in the case of an affiliate, or of a non-affiliate who has held the securities
less than two years, and in some circumstances three years, (3) the sale being
made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker (as said term is defined under the
Securities Exchange Act of 1934) and the amount of securities being sold during
any three month period not exceeding the specified limitations stated therein,
if applicable.

     (e)  I agree, in connection with the Company's initial underwritten public
offering of the Company's securities, (1) not to sell, make 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 me (other than those shares included in the
registration) without the prior written consent of the Company or the
underwriters managing such initial underwritten public offering of the Company's
securities for one hundred eighty (180) days from the effective date of such
registration, and (2) I further agree to execute any agreement reflecting (1)
above as may be requested by the underwriters at the time of the public
offering; provided however that the officers and directors of the Company who
          -------- -------
own the stock of the Company also agree to such restrictions.

     (f)  I further understand that in the event all of the applicable
requirements of Rule 144 are not satisfied, registration under the Securities
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive, the
Staff of the SEC has expressed its opinion that persons proposing to sell
private placement securities other than in a registered offering and otherwise
than pursuant to Rule 144 will have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or
sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk.

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

                           WARRANT TO PURCHASE STOCK

Corporation:             2Bridge Software, A California Corporation
Number of Shares:        85,221 (subject to Section 1.7)
Class of Stock:          Series B Preferred (subject to Section 1.7)
Initial Exercise Price:  $1.4081 per share (subject to Section 1.7)
Issue Date:              May 1, 1999
Expiration Date:         May 1, 2006 (Subject to Article 4.1)

     THIS WARRANT CERTIFIES THAT, in consideration of the payment of $1.00 and
for other good and valuable consideration, IMPERIAL BANCORP or its registered
assignee (together with its successors and assigns "Holder") is entitled to
purchase the number of fully paid and nonassessable shares of the class of
securities (the "Shares") of the corporation (together with its successors and
assigns, the "Company") at the initial exercise price per Share (the "Warrant
Price") all as set forth above and as adjusted pursuant to Article 2 of this
Warrant, subject to the provisions and upon the terms and conditions set forth
of this Warrant.

ARTICLE 1. EXERCISE
           --------

     1.1  Method of Exercise. Holder may exercise this Warrant by delivering
          ------------------
this Warrant and a duly executed Notice of Exercise in substantially the form
attached as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

     1.2  Conversion Right. In lieu of exercising this Warrant as specified in
          ----------------
Section 1.1, Holder may from time to time convert this Warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.5.
<PAGE>

     1.3  Fair Market Value. If the Shares are traded regularly in a public
          -----------------
market, the fair market value of the Shares shall be the closing price of the
Shares (or the closing price of the Company's stock into which the Shares are
convertible) reported for the business day immediately before Holder delivers
its Notice of Exercise to the Company. If the Shares are not regularly traded in
a public market, the Board of Directors of the Company shall determine the fair
market value in its reasonable good faith judgment. The foregoing
notwithstanding, if Holder advises the Board of Directors in writing that Holder
disagrees with such determination, then the Company and Holder shall promptly
agree upon a reputable investment banking firm to undertake such valuation, if
the valuation of such investment banking firm is greater than five (5%) percent
or more than that determined by the Board of Directors, then all fees and
expenses of such investment banking firm shall be paid by the Company. In all
other circumstances, such fees and expenses shall be paid by Holder.

     1.4  Delivery of Certificate and New Warrant. Promptly after Holder
          ---------------------------------------
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.5  Replacement of Warrants. On receipt of evidence reasonably
          -----------------------
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

     1.6  Repurchase on Sale, Merger, or Consolidation of the Company.
          -----------------------------------------------------------

          1.6.1.  "Acquisition". For the purpose of this Warrant, "Acquisition"
                   -----------
means any sale, license, or other disposition of all or substantially all of the
assets (including intellectual property) of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

          1.6.2.  Assumption of Warrant. If upon the closing of any Acquisition
                  ---------------------
the successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the Unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing. The Warrant Price shall be adjusted
accordingly. The Company shall use reasonable efforts to cause the surviving
corporation to assume the obligations of this Warrant.

          1.6.3.  Nonassumption. If upon the closing of any Acquisition the
                  -------------
successor entity does not assume the obligations of this Warrant and Holder has
not otherwise exercised this Warrant in full, then the unexercised portion of
this Warrant shall be deemed to have been automatically converted pursuant to
Section 1.2 and thereafter Holder shall participate in the Acquisition on the
same terms as other holders of the same class of securities of the Company.

                                       2
<PAGE>

     1.7  Adjustment in Underlying Preferred Stock Price and Exercise Price. If
          -----------------------------------------------------------------
on or before July 31, 1999, the Company sells and issues to any investors,
preferred stock with aggregate gross proceeds to the Company of at least
$6,000,000 (six million dollars), this Warrant shall concurrent with the
issuance of such shares of preferred stock automatically be adjusted to instead
be exercisable for shares of the same series and class and bearing the same
rights, preferences, and privileges, of such shares of stock, with the Warrant
Price hereunder adjusted to equal the per share purchase price of such stock,
and the number of such shares subject to this Warrant adjusted to equal (i) one
hundred twenty thousand dollars ($120,000)*, divided by (ii) such modified per
share Warrant Price.


ARTICLE 2. ADJUSTMENTS TO THE SHARES.
           -------------------------

     2.1  Stock Dividends, Splits, Etc. If the Company declares or pays a
          ----------------------------
dividend on its common stock payable in common stock, or other securities,
subdivides the outstanding common stock into a greater amount of common stock,
then upon exercise of this Warrant, for each Share acquired, Holder shall
receive, without cost to Holder, the total number and kind of securities to
which Holder would have been entitled had Holder owned the Shares of record as
of the date the dividend or subdivision occurred.

     2.2  Reclassification, Exchange or Substitution. Upon any reclassification,
          ------------------------------------------
exchange, substitution, or other event that results in a change of the number
and/or class: of the securities issuable upon exercise or conversion of this
Warrant, Holder shall be entitled to receive, upon exercise or conversion of
this Warrant, the number and kind of securities and property that Holder would
have received for the Shares if this Warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. Such an
event shall include any automatic conversion of the outstanding or issuable
securities of the Company of the same class or series as the Shares to common
stock pursuant to the terms of the Company's Articles of Incorporation upon the
closing of a registered public offering of the Company's common stock. The
Company or its successor shall promptly issue to Holder a new Warrant for such
new securities or other property. The new Warrant shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article 2 including, without limitation, adjustments to the
Warrant Price and to the number of securities or property issuable upon exercise
of the new Warrant. The provisions of this Section 2.2 shall similarly apply to
successive reclassifications, exchanges, substitutions, or other events.

     2.3  Adjustments for Combinations, Etc. If the outstanding shares are
          ---------------------------------
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased.

     2.4  Adjustments for Diluting Issuances. The number of shares of common
          ----------------------------------
stock issuable upon conversion of the Shares issuable upon exercise of this
Warrant shall be subject to adjustment, from time to time, in the manner set
forth on Exhibit A, if attached, in the event of Diluting Issuances (as defined
on Exhibit A).

                                       3
<PAGE>

     2.5  No Impairment. The Company shall not, by amendment of its Articles of
          -------------
Incorporation or through a reorganization, 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 under this Warrant by the Company, but shall at all times
in good faith assist in carrying out all the provisions of this Article 2 and in
taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares or its common stock other than as described above that
adversely affects Holder's rights under this Warrant, the Warrant Price shall be
adjusted downward and the number of Shares issuable upon exercise of this
Warrant shall be adjusted upward in such a manner that the aggregate Warrant
Price of this Warrant is unchanged.

     2.6  Certificate as to Adjustments. Upon each adjustment of the Warrant
          -----------------------------
Price, the Company at its expense shall promptly compute such adjustment, and
furnish Holder with a certificate of its Chief Financial Officer setting forth
such adjustment and the facts upon which such adjustment is based. The Company
shall, upon written request, furnish Holder a certificate setting forth the
Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.
           --------------------------------------------

     3.1  Representations and Warranties. The Company hereby represents and
          ------------------------------
warrants to the Holder as follows:

          (a) The initial Warrant Price referenced on the first page of this
Warrant is not greater than the fair market value of the Shares as of the date
of this Warrant.

          (b) All Shares which may be issued upon the exercise of the purchase
right represented by this Warrant, and all securities, if any, issuable upon
conversion of the Shares, shall, upon issuance, be duly authorized, validly
issued, fully paid and nonassessable, and free of any liens and encumbrances
except for restrictions on transfer provided for herein or under applicable
federal and state securities laws.

     3.2  Notice of Certain Events. If the Company proposes at any time (a) to
          ------------------------
declare any dividend or distribution upon its common stock, whether in cash,
property, stock, or other securities and whether or not a regular cash dividend;
(b) to effect any reclassification or recapitalization of common stock; (c) to
merge or consolidate with or into any other corporation, or sell, lease,
license, or convey all or substantially all of its assets, or to liquidate,
dissolve or wind up; or (d) to offer holders of registration rights the
opportunity to participate in an underwritten public offering of the company's
securities for cash, then, in connection with each such event, the Company shall
give Holder (1) at least 20 days prior written notice of the date on which a
record will be taken for such dividend, distribution, or subscription rights
(and specifying the date on which the holders of common stock will be entitled

                               2BRIDGE SOFTWARE


        WARRANT TO PURCHASE 58, 608 SHARES OF SERIES C PREFERRED STOCK

                                 ____________

     THIS CERTIFIES THAT, for value received, Comdisco, Inc. (the "Holder") is
entitled to subscribe for and purchase from 2Bridge Software, a California
corporation (the "Company"), shares of the Company's fully paid and
nonassessable Series C Preferred Stock (the "Shares"), in the amounts and at the
price per share set forth in Section 1 below (as adjusted pursuant to Section 4
hereof), subject to the provisions and upon the terms and conditions hereinafter
set forth.

     This Warrant is subject to the following terms and conditions:

     1.   Number and Price of Shares.
          --------------------------

          (a)  The Holder shall have the right to purchase 58,608 Shares, which
is equal to one hundred twenty-five thousand dollars ($125,000) divided by the
Exercise Price, as defined in Section 1(b) below.

          (b)  The exercise price per Share ("Exercise Price") shall be equal to
$2.1328 per Share.
<PAGE>

     2.   Method of Exercise; Payment.
          ---------------------------

          (a)  Cash Exercise.  The purchase rights represented by this Warrant
               -------------
may be exercised by the Holder, in whole or in part, from time to time by: (i)
the surrender of this Warrant (with the notice of exercise form (the "Notice of
Exercise") attached hereto as Exhibit A duly executed) at the principal office
                              ---------
of the Company; (ii) the execution of a Series C Preferred Stock Purchase
Agreement and all exhibits thereto, including without limitation an Amended and
Restated Investor Rights Agreement, Voting Agreement, and Co-Sale Agreement
(collectively, the "Series C Transaction Documents"); and (iii)  by the
payment to the Company of an amount equal to the Exercise Price multiplied by
the number of the Shares being purchased, which amount may be paid, at the
election of the Holder, by wire transfer or certified check payable to the order
of the Company.  The person or persons in whose name(s) any certificate(s)
representing Shares shall be issuable upon exercise of this Warrant shall be
deemed to have become the holder(s) of record of, and shall be treated for all
purposes as the record holder(s) of, the Shares represented thereby (and such
Shares shall be deemed to have been issued) immediately prior to the close of
business on the date or dates upon which this Warrant is exercised.

          (b)  Net Issue Exercise.  In lieu of exercising this Warrant pursuant
               ------------------
to Section 2(a) hereof, the Holder may elect to receive a number of Shares equal
to the value (as determined below) of this Warrant (or the portion thereof being
canceled) by surrender of this Warrant and the fully executed Series C
Transaction Documents at the principal office of the Company, together with the
Notice of Exercise in which alternative No. 1 is initiated by the Holder.  In
such event, the Company shall issue to the Holder a number of Shares computed
using the following formula:

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

Where X   =    the number of Shares to be issued to the Holder.

      Y   =    the number of Shares subject to this warrant.

      A   =    the fair market value of one share of the Company's Series C
Preferred Stock.

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

          (c)  Fair Market Value.  For purposes of this Section 2, the fair
               -----------------
market value of the Company's Series C Preferred Stock shall mean:

               (i)  The average of the closing bid and asked prices of the
Company's Common Stock quoted in the Over-The-Counter Market Summary or the
closing price quoted on any exchange on which the Common Stock is listed,
whichever is applicable, as published in the Western

                                       2
<PAGE>

Edition of The Wall Street Journal for the ten trading days prior to the date of
           -----------------------
determination of fair market value multiplied by the number of shares of Common
Stock into which each share of Series B Preferred Stock is convertible;

               (ii) If the Company's Common Stock is not traded Over-The-Counter
or on an exchange, the fair market value of the Series C Preferred Stock per
share shall be the price per share which the Company could obtain from a willing
buyer for shares sold by the Company from authorized but unissued shares of
Series C Preferred Stock as such price shall be agreed by the parties hereto, or
if agreement cannot be reached within five (5) business days of delivery of the
notice pursuant to Section 2(b) hereof, as shall be determined by a panel of
appraisers. One appraiser shall be selected by the Holder, one appraiser shall
be chosen by the Company and the third appraiser shall be chosen by the first
two appraisers. If the appraisers cannot reach agreement as to the fair market
value on the foregoing basis on or before the thirtieth (30th) day following the
Holder's notice of election pursuant to Section 2(b), then each appraiser shall
deliver its appraisal and the appraisal which is neither the highest nor the
lowest shall be the fair market value of a share of Series C Preferred Stock. In
the event that the Holder fails to choose an appraiser or the three appraisers
fail to deliver an appraisal on or before the thirtieth (30th) day after such
notice, the appraisal of the appraiser selected by the Company shall control and
shall be fair market value for the purposes of this Warrant. The cost of the
appraiser selected by each party shall be borne by that party and the cost of
the third appraiser shall be borne one-half (1/2) by each party. Appraisers
selected under this Section 2(c) must be unaffiliated with the Holder and the
Company and must have reasonable professional qualifications for the appraisal.

          (d)  Stock Certificates.  In the event of any exercise of the rights
               ------------------
represented by this Warrant, certificates for the Shares so purchased shall be
delivered to the Holder within a reasonable time and, unless this Warrant has
been fully exercised or has expired, a new Warrant representing the Shares with
respect to which this Warrant shall not have been exercised shall also be issued
to the Holder within such time.

          (e)  Condition of Exercise  Unless exercised pursuant to an effective
               ---------------------
registration statement under the Act which includes the Shares so exercised, it
shall be a condition to any exercise of this Warrant that the Company shall have
received, at the time of such exercise, a representation in writing from the
Holder in the form attached hereto as Exhibit A-1, that the Shares being issued
                                      -----------
upon exercise are being acquired for investment and not with a view to any sale
or distribution thereof.

     3.   Stock Fully Paid; Reservation of Shares.  All of the Shares
          ---------------------------------------
issuable upon the exercise of the rights represented by this Warrant will, upon
issuance and receipt of the Exercise Price therefor, be fully paid and
nonassessable, and free from all preemptive rights, rights of first refusal or
first offer, taxes, liens and charges with respect to the issuance thereof.
During the period within which the rights represented by this Warrant may be
exercised, the Company shall at all times have authorized and reserved for
issuance sufficient shares of its Series C Preferred Stock and Common Stock to
provide for the exercise of the rights represented by this Warrant.

                                       3
<PAGE>

     4.   Adjustment of Exercise Price and Number of Shares.  The number and
          -------------------------------------------------
kind of Shares purchasable upon the exercise of this Warrant and the Exercise
Price therefor shall be subject to adjustment from time to time upon the
occurrence of certain events, as follows:

          (a)  Stock Splits, Dividends and Combinations.  In the event that the
               ----------------------------------------
Company shall at any time subdivide the outstanding shares of Series C Preferred
Stock, or shall issue a stock dividend on its outstanding shares of Series C
Preferred Stock, the number of Shares issuable upon exercise of this Warrant
immediately prior to such subdivision or to the issuance of such stock dividend
shall be proportionately increased, and the Exercise Price shall be
proportionately decreased, and in the event that the Company shall at any time
combine the outstanding shares of Series C Preferred Stock, the number of Shares
issuable upon exercise of this Warrant immediately prior to such combination
shall be proportionately decreased, and the Exercise Price shall be
proportionately increased, effective at the close of business on the date of
such subdivision, stock dividend or combination, as the case may be.

          (b)  Price Adjustments. If at any time the Company issues or sells any
               -----------------
shares of its Preferred Stock for a consideration per share less than the then
effective Exercise Price, then and in each such case, the Exercise Price for the
Shares will be reduced to a price (calculated to the nearest cent) determined by
multiplying such applicable Exercise Price by a fraction (a) the numerator of
which will be the number of shares of Preferred Stock outstanding (or so deemed)
immediately prior to such issuance or sale plus the number of shares of Series C
Preferred Stock which the aggregate consideration received by the Company for
such issuance or sale would purchase at such applicable Exercise Price, and (b)
the denominator of which will be the number of shares of Preferred Stock
outstanding (or so deemed) immediately after the Preferred Stock proposed to be
issued or sold is issued or sold; provided that such fraction will in no event
be greater than one (1). For purposes of this Section 4(b), the Shares will be
deemed to be outstanding on the date hereof.

          For the purpose of making any adjustment in the Exercise Price as
provided above, the consideration received by the Company for any issuance or
sale of Preferred Stock will be computed:

                    (A)  to the extent it consists of cash, as the amount of
cash received by the Company before deduction of any offering expenses payable
by the Company and any underwriting or similar commissions, compensation, or
concessions paid or allowed by the Company in connection with such issuance or
sale;

                    (B)  to the extent it consists of property other than cash,
at the fair market value of that property as determined in good faith by the
Company's Board of Directors; and

                    (C)  if Preferred Stock is issued or sold together with
other stock or securities or other assets of the Company for a consideration
which covers both, as the portion of the consideration so received that may be
reasonably determined in good faith by the Board of Directors to be allocable to
such Preferred Stock.

                                       4
<PAGE>

          No adjustment to the Exercise Price pursuant to this Section 4(b)
shall affect the number of Warrants to be issued pursuant to Section 1(a)
herein.

          (c)  Recapitalizations.  If at any time or from time to time there
               -----------------
shall be a recapitalization of the Series C Preferred Stock (other than a
subdivision, combination or merger or sale of assets transaction provided for
elsewhere in this Section 4), provision shall be made so that the Holder of this
Warrant will thereafter be entitled to receive upon exercise of this Warrant the
number of shares of stock or other securities or property of the Company to
which a Holder of Series B Preferred Stock would have been entitled on such
recapitalization.  In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 4 with respect to the rights of
the Holder of this Warrant after the recapitalization to the end that the
provisions of this Section 4 (including adjustment of the Exercise Price then in
effect and the number of shares issuable upon exercise of this Warrant) shall be
applicable after that event in as nearly an equivalent manner as may be
practicable.

          (d)  Merger. If at any time there shall be a capital reorganization of
               ------
the shares of the Company's stock (other than a combination, reclassification,
exchange or subdivision of shares otherwise provided for herein), or a merger or
consolidation of the Company with or into another corporation, whether or not
the Company is the surviving corporation, other than as provided for in Section
10(a) herein (a "Merger Event"), then as a part of such Merger Event, lawful
provision shall be made so that the Holder shall thereafter be entitled to
receive, upon exercise of the Warrant, the number of shares of stock or other
securities of the successor corporation resulting from such Merger Event,
equivalent in value to that which would have been issuable if Holder had
exercised this Warrant immediately prior to the Merger Event. In any such case,
appropriate adjustment (as determined in good faith by the Company's Board of
Directors) shall be made in the application of the provisions of this Warrant
with respect to the rights and interest of the Holder after the Merger Event to
the end that the provisions of this Warrant (including adjustments of the
Exercise Price and number of Shares purchasable) shall be applicable to the
greatest extent possible.

          (e)  Notices.  Upon any adjustment of the Exercise Price and any
               -------
increase or decrease in the number of Shares purchasable upon the exercise of
this Warrant in accordance with Section 3 hereof, then, and in each such case,
the Company, within thirty (30) days thereafter, shall give written notice
thereof to the Holder at the address of such Holder as shown on the books of the
Company which notice shall state the Exercise Price as adjusted and, if
applicable, the increased or decreased number of Shares purchasable upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation of each.   Any written notice by the Company required or permitted
hereunder shall be given by hand delivery or first class mail, postage prepaid,
addressed to the Holder at the address shown on the books of the Company for the
Holder.

     5.   Restrictions on Transfer.
          ------------------------

          (a)  Holder agrees not to make any disposition of all or any portion
of the Shares or the Warrant unless and until:

               (i)  There is then in effect a registration statement under the
1933 Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

               (ii) Holder shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition, and the transferee has
agreed in writing to be bound by this Section 5. If reasonably requested by the
Company, Holder shall furnish the Company with an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will not require registration
of such shares under the 1933 Act. Notwithstanding the foregoing, the
restrictions imposed upon the transferability of any of the Shares or rights to
acquire Shares do not apply to transfers from the beneficial owner of any of the
aforementioned securities to its nominee or from such nominee to its beneficial
owners, and shall terminate as to any particular Shares when a letter shall have
been issued to Holder at its request by the staff of the Securities and Exchange
Commission or a ruling shall have been issued to the Holder at its request by
such Commission stating that no action shall be recommended by such staff or
taken by such Commission, as the case may be, if such security is transferred
without registration under the 1933 Act in accordance with the conditions set
forth in such letter or ruling and such letter or ruling specifies that no
subsequent restrictions on transfer are required. It is agreed that the Company
will not require opinions of counsel for transactions made pursuant to Rule 144
except in unusual circumstances.

          (b)  Notwithstanding the above, the Shares shall also be subject to
all restrictions on transfer set forth in the Series C Transaction Documents,
including without limitation a 180 day market standoff period upon the Company's
initial public offering.

     6.   Fractional Shares. No fractional shares of Common Stock will be issued
          -----------------
in connection with any exercise hereunder, but in lieu of such fractional shares
the Company shall make a cash payment therefor upon the basis of the Exercise
Price then in effect.

     7.   Representations and Warranties by the Company.
          ---------------------------------------------

          (a)  Due Authority.  The execution and delivery by the Company of this
               -------------
Warrant and the performance of all obligations of the Company hereunder,
including the issuance to Holder of the right to acquire Shares, have been duly
authorized by all necessary corporate action on the part of the Company.  This
Warrant is consistent with the Company's Amended and Restated Articles of
Incorporation, and does not contravene any law or governmental rule, regulation
or order applicable to it, and does not and will not contravene any provision
of, or constitute a default under, any indenture, mortgage, contract or other
instrument to which it is a party or by which it is bound.  This

                                       6
<PAGE>

Warrant constitutes a legal, valid and binding agreement of the Company,
enforceable in accordance with its respective terms.

          (b)  Consents and Approvals.  No consent or approval of, giving of
               ----------------------
notice to, registration with, or taking of any other action in respect of any
state, Federal or other governmental authority or agency is required with
respect to the execution, delivery and performance by the Company of its
obligations under this Warrant, except for the filing of notices pursuant to
Regulation D under the 1933 Act and any filing required by applicable state
securities law, which filings shall be made by the time required thereby.

          (c)  Holder's Additional Rights.  The Series C Preferred Stock shall
               --------------------------
have anti-dilution rights, registration rights, and information rights
substantially similar to those rights given to holders of the Company's Series C
Preferred Stock, which rights shall be set forth in the Series C Transaction
Documents.

          (d)  Other Commitments to Register Securities.  Except as set forth
               ----------------------------------------
(i) herein, (ii) in the Investor Rights Agreement dated as of January 17, 1997,
(iii) the Warrants issued to Holder as of November 20, 1997, March 11, 1998,
July 23, 1999,  and the date hereof, and (iv) the warrant issued to Imperial
Bank on May 1, 1999, the Company is not, pursuant to the terms of any other
agreement currently in existence, under any obligation to register under the
Securities Act any of its presently outstanding securities or any of its
securities which may hereafter be issued.

          (e)  Exempt Transaction.  Subject to the accuracy of the Holder's
               ------------------
representations in this Section 11 and any filing necessary to obtain a state
securities law exemption, the issuance of Shares upon exercise of this Warrant
will constitute a transaction exempt from (i) the registration requirements of
Section 5 of the Securities Act, and (ii) the qualification requirements of the
applicable state securities laws.

          (f)  Compliance with Rule 144.  At the written request of Holder, who
               ------------------------
proposes to sell Warrant Shares issuable upon the exercise of this Warrant in
compliance with Rule 144 promulgated by the Securities and Exchange Commission,
the Company shall furnish to Holder, within ten (10) days after receipt of such
request, a written statement confirming the Company's compliance with the filing
requirements of the Securities and Exchange Commission as set forth in such
Rule, as such Rule may be amended from time to time.

     8.   Representations and Warranties by the Holder. Holder represents and
          --------------------------------------------
warrants to the Company as follows:

          (a)  This Warrant is being acquired for Holder's own account, for
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Act, and the
Holder has no present intention of selling or engaging in any public
distribution thereof pursuant to a registration or exemption.

                                       7
<PAGE>

          (b)  Holder understands that the Warrant and the Shares have not been
registered under the Act by reason of their issuance in a transaction exempt
from the registration and prospectus delivery requirements of the Act pursuant
to Section 4(2) thereof, and that they must be held by Holder indefinitely, and
that Holder must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Act or is exempted from such registration.  The Holder further understands that
the Shares have not been qualified under the California Securities Law of 1968
(the "California Law") by reason of their issuance in a transaction exempt from
the qualification requirements of the California Law pursuant to Section
25102(f) thereof, which exemption depends upon, among other things, the bona
fide nature of the Holder's investment intent expressed above.

          (c)  The Holder has such knowledge and experience in financial and
business matters that it is capable of evaluating the merits and risks of the
purchase of this Warrant and the Shares purchasable pursuant to the terms of
this Warrant and of protecting its interests in connection therewith.

          (d)  The Holder is able to bear the economic risk of the purchase of
the Shares pursuant to the terms of this Warrant.

     9.   Rights of Stockholders. Nothing contained herein shall confer upon
          ----------------------
Holder any of the rights of a stockholder of the Company or any right to vote
for the election of directors or upon any matter submitted to stockholders at
any meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of
stock, change of par value, consolidation, merger, conveyance, or otherwise) or
to receive notice of meetings, or to receive dividends or subscription rights or
otherwise until the Warrant shall have been exercised and the Shares purchasable
upon the exercise hereof shall have become deliverable, as provided herein.

     10.  Expiration of Warrant.
          ---------------------

          (a)  This Warrant shall expire and shall no longer be exercisable as
of the earlier of:

               (i)   5:00 p.m., California local time, on July 23, 2009;

               (ii)  five (5) years after the Company's initial public offering
under the Securities Act of 1933, as amended;

               (iii) the automatic conversion of the Series C Preferred Stock of
the Company into Common Stock of the Company, according to the terms of the
Series C Transaction Documents, provided that Company provides Holder with at
least thirty (30) days notice of such automatic conversion and that it gives
Holder an option in Holder's sole discretion to either exercise the Warrant or
cause Company to replace the Warrant with a Warrant to Purchase Common Stock on
substantially the same terms as those set forth herein;

                                       8
<PAGE>

               (iv) a consolidation or merger of the Company with or into
another corporation (other than a consolidation or merger with another
corporation in which the Company's stockholders immediately preceding such
consolidation or merger own at least 50% of the voting securities of the
successor entity following such consolidation or merger and which does not
result in any reclassification of the Shares issuable upon exercise of this
Warrant); or

               (v)  a sale of all or substantially all of the assets of the
Company.

     11.  Miscellaneous.
          -------------

          (a)  This Warrant is being delivered in the State of California and
shall be construed and enforced in accordance with and governed by the laws of
such State.  The parties expressly stipulate that any litigation under this
Warrant shall be brought in the State courts of the Counties of Santa Clara or
San Francisco, California and in the United States District Court for the

claim or dispute involving questions of usury law as it applies to the Warrant
shall be governed by the laws of Illinois.

and shall not limit or otherwise affect any of the terms hereof.

          (c)  The terms of this Warrant shall be binding upon and shall inure
to the benefit of any successors in interest of the Company or the Holder. This
Warrant and all rights hereunder are not assignable or transferable by Company
or Holder, except for such permitted transfers to successors in interest and in
accordance with Section 5 herein, and any attempt to assign or transfer the
rights hereunder shall be void and of no further effect.

          (d)  This Warrant and the other documents delivered pursuant hereto,
including without limitation the Series C Transaction Documents, constitute the
full and entire understanding and agreement between the parties with regard to
the subjects hereof and thereof.

          (e)  The Company shall not, by amendment of its Amended and Restated
Articles of Incorporation, or through any other means, directly or indirectly,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant and shall at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the holder of this Warrant against
impairment.

          (f)  Upon receipt of evidence reasonably satisfactory to the Company
of the loss, theft, destruction or mutilation of this Warrant and, in the case
of any such loss, theft or destruction, upon delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of any
such mutilation, upon surrender and cancellation of such Warrant, the Company at
its expense will execute and deliver to the holder of record, in lieu thereof, a
new Warrant of like date and tenor.

                      INVESTMENT REPRESENTATION STATEMENT

PURCHASER :    COMDISCO, INC.

COMPANY   :    2BRIDGE SOFTWARE

SECURITY  :    SERIES C PREFERRED STOCK ISSUED UPON EXERCISE OF THE SERIES C
               PREFERRED STOCK PURCHASE WARRANT ISSUED ON JULY 23, 1999

AMOUNT    :    _______________ SHARES

DATE      :    ___________________, ______

In connection with the purchase of the above-listed Securities, I, the
Purchaser, represent to the Company the following:

     (a)  I am aware of the Company's business affairs and financial condition,
and have acquired sufficient information about the Company to reach an informed
and knowledgeable decision to acquire the Securities. I am purchasing these
Securities for my own account for investment purposes only and not with a view
to, or for the resale in connection with, any "distribution" thereof for
purposes of the Securities Act of 1933, as amended (the "Securities Act") except
pursuant to a registration of exemption.

     (b)  I understand that the Securities have not been registered under the
Securities Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of my investment intent
as expressed herein.  In this connection, I understand that, in the view of the
Securities and Exchange Commission (the "SEC"), the statutory basis for such
exemption may be unavailable if my representation was predicated solely upon a
present intention to hold these Securities for the minimum capital gains period
specified under tax statutes, for a deferred sale, for or until an increase or
decrease in the market price of the Securities, or for a period of one year or
any other fixed period in the future.

     (c)  I further understand that the Securities must be held indefinitely
unless subsequently registered under the Securities Act or unless an exemption
from registration is otherwise available. Moreover, I understand that the
Company is under no obligation to register the Securities. In addition, I
understand that the certificate evidencing the Securities will be imprinted with
a legend which prohibits the transfer of the Securities unless they are
registered or such registration is not required in the opinion of counsel for
the Company.

     (d)  I am familiar with the provisions of Rule 144, promulgated under
the Securities Act, which, in substance, permits limited public resale of
"restricted securities" acquired, directly or
<PAGE>

indirectly, from the issuer thereof, in a non-public offering subject to the
satisfaction of certain conditions.

     The Securities may be resold in certain limited circumstances subject to
the provisions of Rule 144, which requires among other things: (1) the
availability of certain public information about the Company, (2) the resale
occurring not less than one year, and in some circumstances two years, after the
party has held, within the meaning of Rule 144, the securities to be sold; and,
in the case of an affiliate, or of a non-affiliate who has held the securities
less than two years, and in some circumstances three years, (3) the sale being
made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker (as said term is defined under the
Securities Exchange Act of 1934) and the amount of securities being sold during
any three month period not exceeding the specified limitations stated therein,
if applicable.

     (e)  I agree, in connection with the Company's initial underwritten public
offering of the Company's securities, (1) not to sell, make 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 me (other than those shares included in the
registration) without the prior written consent of the Company or the
underwriters managing such initial underwritten public offering of the Company's
securities for one hundred eighty (180) days from the effective date of such
registration, and (2) I further agree to execute any agreement reflecting (1)
above as may be requested by the underwriters at the time of the public
offering; provided however that the officers and directors of the Company who
          -------- -------
own the stock of the Company also agree to such restrictions.

     (f)  I further understand that in the event all of the applicable
requirements of Rule 144 are not satisfied, registration under the Securities
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive, the
Staff of the SEC has expressed its opinion that persons proposing to sell
private placement securities other than in a registered offering and otherwise
than pursuant to Rule 144 will have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or
sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk.

OF SERIES C PREFERRED STOCK ISSUABLE HEREUNDER OR ANY SHARES INTO WHICH SUCH
SHARES ARE CONVERTIBLE, (TOGETHER, THE "SECURITIES") HAVE BEEN REGISTERED UNDER

LAWS.  SUCH SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
HYPOTHECATED IN THE ABSENCE OF SUCH REGISTRATION OR AN OPINION OF COUNSEL
SATISFACTORY TO THE COMPANY AND ITS COUNSEL THAT SUCH DISPOSITION IS EXEMPT FROM
THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF THE ACT AND OF ANY
APPLICABLE STATE SECURITIES LAWS.

                               2BRIDGE SOFTWARE

         WARRANT TO PURCHASE 5,861 SHARES OF SERIES C PREFERRED STOCK

                                 ____________

     THIS CERTIFIES THAT, for value received, Comdisco, Inc. (the "Holder") is
entitled to subscribe for and purchase from 2Bridge Software, a California
corporation (the "Company"), shares of the Company's fully paid and
nonassessable Series C Preferred Stock (the "Shares"), in the amounts and at the
price per share set forth in Section 1 below (as adjusted pursuant to Section 4
hereof), subject to the provisions and upon the terms and conditions hereinafter
set forth.

     This Warrant is subject to the following terms and conditions:

     1.   Number and Price of Shares.
          --------------------------

          (a)  The Holder shall have the right to purchase five thousand eight
hundred sixty-one (5,861) Shares, which is equal to twelve thousand five hundred
dollars ($12,500) divided by the Exercise Price, as defined in Section 1(b)
below.

          (b)  The exercise price per Share ("Exercise Price") shall be equal to
$2.1328 per Share.

<PAGE>

     2.   Method of Exercise; Payment.
          ---------------------------

          (a)  Cash Exercise.  The purchase rights represented by this Warrant
               -------------
may be exercised by the Holder, in whole or in part, from time to time by: (i)
the surrender of this Warrant (with the notice of exercise form (the "Notice of
Exercise") attached hereto as Exhibit A duly executed) at the principal office
                              ---------
of the Company; (ii) the execution of a Series C Preferred Stock Purchase
Agreement and all exhibits thereto, including without limitation an Amended and
Restated Investor Rights Agreement, Voting Agreement, and Co-Sale Agreement
(collectively, the "Series C Transaction Documents"); and (iii)  by the payment
to the Company of an amount equal to the Exercise Price multiplied by the number
of the Shares being purchased, which amount may be paid, at the election of the
Holder, by wire transfer or certified check payable to the order of the Company.
The person or persons in whose name(s) any certificate(s) representing Shares
shall be issuable upon exercise of this Warrant shall be deemed to have become
the holder(s) of record of, and shall be treated for all purposes as the record
holder(s) of, the Shares represented thereby (and such Shares shall be deemed to
have been issued) immediately prior to the close of business on the date or
dates upon which this Warrant is exercised.

          (b)  Net Issue Exercise.  In lieu of exercising this Warrant pursuant
               ------------------
to Section 2(a) hereof, the Holder may elect to receive a number of Shares equal
to the value (as determined below) of this Warrant (or the portion thereof being
canceled) by surrender of this Warrant and the fully executed Series C
Transaction Documents at the principal office of the Company, together with the
Notice of Exercise in which alternative No. 1 is initiated by the Holder.  In
such event, the Company shall issue to the Holder a number of Shares computed
using the following formula:


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


Where X   =   the number of Shares to be issued to the Holder.

      Y   =   the number of Shares subject to this warrant.

      A   =   the fair market value of one share of the Company's Series C
              Preferred Stock.

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

          (c) Fair Market Value.  For purposes of this Section 2, the fair
              -----------------
market value of the Company's Series C Preferred Stock shall mean:

              (i)  The average of the closing bid and asked prices of the
Company's Common Stock quoted in the Over-The-Counter Market Summary or the
closing price quoted on any exchange on which the Common Stock is listed,
whichever is applicable, as published in the Western Edition of The Wall Street
                                                                ---------------
Journal for the ten trading days prior to the date of determination of fair
- -------

                                       2
<PAGE>

market value multiplied by the number of shares of Common Stock into which each
share of Series B Preferred Stock is convertible;

               (ii)  If the Company's Common Stock is not traded Over-The-
Counter or on an exchange, the fair market value of the Series C Preferred Stock
per share shall be the price per share which the Company could obtain from a
willing buyer for shares sold by the Company from authorized but unissued shares
of Series C Preferred Stock as such price shall be agreed by the parties hereto,
or if agreement cannot be reached within five (5) business days of delivery of
the notice pursuant to Section 2(b) hereof, as shall be determined by a panel of
appraisers. One appraiser shall be selected by the Holder, one appraiser shall
be chosen by the Company and the third appraiser shall be chosen by the first
two appraisers. If the appraisers cannot reach agreement as to the fair market
value on the foregoing basis on or before the thirtieth (30th) day following the
Holder's notice of election pursuant to Section 2(b), then each appraiser shall
deliver its appraisal and the appraisal which is neither the highest nor the
lowest shall be the fair market value of a share of Series C Preferred Stock. In
the event that the Holder fails to choose an appraiser or the three appraisers
fail to deliver an appraisal on or before the thirtieth (30th) day after such
notice, the appraisal of the appraiser selected by the Company shall control and
shall be fair market value for the purposes of this Warrant. The cost of the
appraiser selected by each party shall be borne by that party and the cost of
the third appraiser shall be borne one-half (1/2) by each party. Appraisers
selected under this Section 2(c) must be unaffiliated with the Holder and the
Company and must have reasonable professional qualifications for the appraisal.

          (d)  Stock Certificates.  In the event of any exercise of the rights
               ------------------
represented by this Warrant, certificates for the Shares so purchased shall be
delivered to the Holder within a reasonable time and, unless this Warrant has
been fully exercised or has expired, a new Warrant representing the Shares with
respect to which this Warrant shall not have been exercised shall also be issued
to the Holder within such time.

          (e)  Condition of Exercise  Unless exercised pursuant to an effective
               ---------------------
registration statement under the Act which includes the Shares so exercised, it
shall be a condition to any exercise of this Warrant that the Company shall have
received, at the time of such exercise, a representation in writing from the
Holder in the form attached hereto as Exhibit A-1, that the Shares being issued
                                      -----------
upon exercise are being acquired for investment and not with a view to any sale
or distribution thereof.

     3.   Stock Fully Paid; Reservation of Shares.  All of the Shares issuable
          ---------------------------------------
upon the exercise of the rights represented by this Warrant will, upon issuance
and receipt of the Exercise Price therefor, be fully paid and nonassessable, and
free from all preemptive rights, rights of first refusal or first offer, taxes,
liens and charges with respect to the issuance thereof.  During the period
within which the rights represented by this Warrant may be exercised, the
Company shall at all times have authorized and reserved for issuance sufficient
shares of its Series C Preferred Stock and Common Stock to provide for the
exercise of the rights represented by this Warrant.

                                       3
<PAGE>

     4.   Adjustment of Exercise Price and Number of Shares.  The number and
          -------------------------------------------------
kind of Shares purchasable upon the exercise of this Warrant and the Exercise
Price therefor shall be subject to adjustment from time to time upon the
occurrence of certain events, as follows:

          (a)  Stock Splits, Dividends and Combinations.  In the event that the
               ----------------------------------------
Company shall at any time subdivide the outstanding shares of Series C Preferred
Stock, or shall issue a stock dividend on its outstanding shares of Series C
Preferred Stock, the number of Shares issuable upon exercise of this Warrant
immediately prior to such subdivision or to the issuance of such stock dividend
shall be proportionately increased, and the Exercise Price shall be
proportionately decreased, and in the event that the Company shall at any time
combine the outstanding shares of Series C Preferred Stock, the number of Shares
issuable upon exercise of this Warrant immediately prior to such combination
shall be proportionately decreased, and the Exercise Price shall be
proportionately increased, effective at the close of business on the date of
such subdivision, stock dividend or combination, as the case may be.

          (b)  Price Adjustments. If at any time the Company issues or sells any
               -----------------
shares of its Preferred Stock for a consideration per share less than the then
effective Exercise Price, then and in each such case, the Exercise Price for the
Shares will be reduced to a price (calculated to the nearest cent) determined by
multiplying such applicable Exercise Price by a fraction (a) the numerator of
which will be the number of shares of Preferred Stock outstanding (or so deemed)
immediately prior to such issuance or sale plus the number of shares of Series C
Preferred Stock which the aggregate consideration received by the Company for
such issuance or sale would purchase at such applicable Exercise Price, and (b)
the denominator of which will be the number of shares of Preferred Stock
outstanding (or so deemed) immediately after the Preferred Stock proposed to be
issued or sold is issued or sold; provided that such fraction will in no event
be greater than one (1). For purposes of this Section 4(b), the Shares will be
deemed to be outstanding on the date hereof.

          For the purpose of making any adjustment in the Exercise Price as
provided above, the consideration received by the Company for any issuance or
sale of Preferred Stock will be computed:

                    (A)  to the extent it consists of cash, as the amount of
cash received by the Company before deduction of any offering expenses payable
by the Company and any underwriting or similar commissions, compensation, or
concessions paid or allowed by the Company in connection with such issuance or
sale;

                    (B)  to the extent it consists of property other than cash,
at the fair market value of that property as determined in good faith by the
Company's Board of Directors; and

                    (C)  if Preferred Stock is issued or sold together with
other stock or securities or other assets of the Company for a consideration
which covers both, as the portion of the consideration so received that may be
reasonably determined in good faith by the Board of Directors to be allocable to
such Preferred Stock.

                                       4
<PAGE>

          No adjustment to the Exercise Price pursuant to this Section 4(b)
shall affect the number of Warrants to be issued pursuant to Section 1(a)
herein.

          (c)  Recapitalizations.  If at any time or from time to time there
               -----------------
shall be a recapitalization of the Series C Preferred Stock (other than a
subdivision, combination or merger or sale of assets transaction provided for
elsewhere in this Section 4), provision shall be made so that the Holder of this
Warrant will thereafter be entitled to receive upon exercise of this Warrant the
number of shares of stock or other securities or property of the Company to
which a Holder of Series B Preferred Stock would have been entitled on such
recapitalization.  In any such case, appropriate adjustment shall be made in the
application of the provisions of this Section 4 with respect to the rights of
the Holder of this Warrant after the recapitalization to the end that the
provisions of this Section 4 (including adjustment of the Exercise Price then in
effect and the number of shares issuable upon exercise of this Warrant) shall be
applicable after that event in as nearly an equivalent manner as may be
practicable.

          (d)  Merger.  If at any time there shall be a capital reorganization
               ------
of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation, whether or not the Company is the surviving corporation, other than
as provided for in Section 10(a) herein (a "Merger Event"), then as a part of
such Merger Event, lawful provision shall be made so that the Holder shall
thereafter be entitled to receive, upon exercise of the Warrant, the number of
shares of stock or other securities of the successor corporation resulting from
such Merger Event, equivalent in value to that which would have been issuable if
Holder had exercised this Warrant immediately prior to the Merger Event. In any
such case, appropriate adjustment (as determined in good faith by the Company's
Board of Directors) shall be made in the application of the provisions of this
Warrant with respect to the rights and interest of the Holder after the Merger
Event to the end that the provisions of this Warrant (including adjustments of
the Exercise Price and number of Shares purchasable) shall be applicable to the
greatest extent possible.

          (e)  Notices.  Upon any adjustment of the Exercise Price and any
               -------
increase or decrease in the number of Shares purchasable upon the exercise of
this Warrant in accordance with Section 3 hereof, then, and in each such case,
the Company, within thirty (30) days thereafter, shall give written notice
thereof to the Holder at the address of such Holder as shown on the books of the
Company which notice shall state the Exercise Price as adjusted and, if
applicable, the increased or decreased number of Shares purchasable upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation of each.  Any written notice by the Company required or permitted
hereunder shall be given by hand delivery or first class mail, postage prepaid,
addressed to the Holder at the address shown on the books of the Company for the
Holder.

     5.   Restrictions on Transfer.
          ------------------------

          (a) Holder agrees not to make any disposition of all or any portion of
the Shares or the Warrant unless and until:

              (i)   There is then in effect a registration statement under the
1933 Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

              (ii)  Holder shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition, and the transferee has
agreed in writing to be bound by this Section 5.  If reasonably requested by the
Company, Holder shall furnish the Company with an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will not require registration
of such shares under the 1933 Act.  Notwithstanding the foregoing, the
restrictions imposed upon the transferability of any of the Shares or rights to
acquire Shares do not apply to transfers from the beneficial owner of any of the
aforementioned securities to its nominee or from such nominee to its beneficial
owners, and shall terminate as to any particular Shares when a letter shall have
been issued to Holder at its request by the staff of the Securities and Exchange
Commission or a ruling shall have been issued to the Holder at its request by
such Commission stating that no action shall be recommended by such staff or
taken by such Commission, as the case may be, if such security is transferred
without registration under the 1933 Act in accordance with the conditions set
forth in such letter or ruling and such letter or ruling specifies that no
subsequent restrictions on transfer are required.  It is agreed that the Company
will not require opinions of counsel for transactions made pursuant to Rule 144
except in unusual circumstances.

          (b) Notwithstanding the above, the Shares shall also be subject to all
restrictions on transfer set forth in the Series C Transaction Documents,
including without limitation a 180 day market standoff period upon the Company's
initial public offering.

     6.   Fractional Shares.  No fractional shares of Common Stock will be
          -----------------
issued in connection with any exercise hereunder, but in lieu of such fractional
shares the Company shall make a cash payment therefor upon the basis of the
Exercise Price then in effect.

     7.   Representations and Warranties by the Company.
          ---------------------------------------------

          (a) Due Authority.  The execution and delivery by the Company of this
              -------------
Warrant and the performance of all obligations of the Company hereunder,
including the issuance to Holder of the right to acquire Shares, have been duly
authorized by all necessary corporate action on the part of the Company.  This
Warrant is consistent with the Company's Amended and Restated Articles of
Incorporation, and does not contravene any law or governmental rule, regulation
or order applicable to it, and does not and will not contravene any provision
of, or constitute a default under, any indenture, mortgage, contract or other
instrument to which it is a party or by which it is bound.  This

                                       6
<PAGE>

Warrant constitutes a legal, valid and binding agreement of the Company,
enforceable in accordance with its respective terms.

          (b) Consents and Approvals.  No consent or approval of, giving of
              ----------------------
notice to, registration with, or taking of any other action in respect of any
state, Federal or other governmental authority or agency is required with
respect to the execution, delivery and performance by the Company of its
obligations under this Warrant, except for the filing of notices pursuant to
Regulation D under the 1933 Act and any filing required by applicable state
securities law, which filings shall be made by the time required thereby.

          (c) Holder's Additional Rights.  The Series C Preferred Stock shall
              --------------------------
have anti-dilution rights, registration rights, and information rights
substantially similar to those rights given to holders of the Company's Series C
Preferred Stock, which rights shall be set forth in the Series C Transaction
Documents.

          (d) Other Commitments to Register Securities.  Except as set forth (i)
              ----------------------------------------
herein, (ii) in the Investor Rights Agreement dated as of January 17, 1997,
(iii) the Warrants issued to Holder as of November 20, 1997, March 11, 1998,
April 30, 1999,  and the date hereof, and (iv) the warrants issued to Imperial
Bank on May 1, 1999, the Company is not, pursuant to the terms of any other
agreement currently in existence, under any obligation to register under the
Securities Act any of its presently outstanding securities or any of its
securities which may hereafter be issued.

          (e) Exempt Transaction.  Subject to the accuracy of the Holder's
              ------------------
representations in this Section 11 and any filing necessary to obtain a state
securities law exemption, the issuance of Shares upon exercise of this Warrant
will constitute a transaction exempt from (i) the registration requirements of
Section 5 of the Securities Act, and (ii) the qualification requirements of the
applicable state securities laws.

          (f) Compliance with Rule 144.  At the written request of Holder, who
              ------------------------
proposes to sell Warrant Shares issuable upon the exercise of this Warrant in
compliance with Rule 144 promulgated by the Securities and Exchange Commission,
the Company shall furnish to Holder, within ten (10) days after receipt of such
request, a written statement confirming the Company's compliance with the filing
requirements of the Securities and Exchange Commission as set forth in such
Rule, as such Rule may be amended from time to time.

     8.   Representations and Warranties by the Holder.  Holder represents and
          --------------------------------------------
warrants to the Company as follows:

          (a) This Warrant is being acquired for Holder's own account, for
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Act, and the
Holder has no present intention of selling or engaging in any public
distribution thereof pursuant to a registration or exemption.

                                       7
<PAGE>

          (b) Holder understands that the Warrant and the Shares have not been
registered under the Act by reason of their issuance in a transaction exempt
from the registration and prospectus delivery requirements of the Act pursuant
to Section 4(2) thereof, and that they must be held by Holder indefinitely, and
that Holder must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Act or is exempted from such registration.  The Holder further understands that
the Shares have not been qualified under the California Securities Law of 1968
(the "California Law") by reason of their issuance in a transaction exempt from
the qualification requirements of the California Law pursuant to Section
25102(f) thereof, which exemption depends upon, among other things, the bona
fide nature of the Holder's investment intent expressed above.

          (c) The Holder has such knowledge and experience in financial and
business matters that it is capable of evaluating the merits and risks of the
purchase of this Warrant and the Shares purchasable pursuant to the terms of
this Warrant and of protecting its interests in connection therewith.

          (d) The Holder is able to bear the economic risk of the purchase of
the Shares pursuant to the terms of this Warrant.

     9.   Rights of Stockholders.  Nothing contained herein shall confer upon
          ----------------------
Holder any of the rights of a stockholder of the Company or any right to vote
for the election of directors or upon any matter submitted to stockholders at
any meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of
stock, change of par value, consolidation, merger, conveyance, or otherwise) or
to receive notice of meetings, or to receive dividends or subscription rights or
otherwise until the Warrant shall have been exercised and the Shares purchasable
upon the exercise hereof shall have become deliverable, as provided herein.

     10.  Expiration of Warrant.
          ---------------------

          (a) This Warrant shall expire and shall no longer be exercisable as of
the earlier of:

              (i)   5:00 p.m., California local time, on July 23, 2002;

              (ii)  five (5) years after the Company's initial public offering
under the Securities Act of 1933, as amended;

              (iii) the automatic conversion of the Series C Preferred Stock of
the Company into Common Stock of the Company, according to the terms of the
Series C Transaction Documents, provided that Company provides Holder with at
least thirty (30) days notice of such automatic conversion and that it gives
Holder an option in Holder's sole discretion to either exercise the Warrant or
cause Company to replace the Warrant with a Warrant to Purchase Common Stock on
substantially the same terms as those set forth herein;

                                       8
<PAGE>

              (iv)  a consolidation or merger of the Company with or into
another corporation (other than a consolidation or merger with another
corporation in which the Company's stockholders immediately preceding such
consolidation or merger own at least 50% of the voting securities of the
successor entity following such consolidation or merger and which does not
result in any reclassification of the Shares issuable upon exercise of this
Warrant); or

              (v)   a sale of all or substantially all of the assets of the
Company.

     11.  Miscellaneous.
          -------------

          (a) This Warrant is being delivered in the State of California and
shall be construed and enforced in accordance with and governed by the laws of
such State.  The parties expressly stipulate that any litigation under this
Warrant shall be brought in the State courts of the Counties of Santa Clara or
San Francisco, California and in the United States District Court for the
Northern District of California.  The parties agree to submit to the
jurisdiction and venue of those courts.  Notwithstanding the foregoing, any
claim or dispute involving questions of usury law as it applies to the Warrant
shall be governed by the laws of California.

          (b) The headings in this Warrant are for purposes of reference only,
and shall not limit or otherwise affect any of the terms hereof.

          (c) The terms of this Warrant shall be binding upon and shall inure to
the benefit of any successors in interest of the Company or the Holder.  This
Warrant and all rights hereunder are not assignable or transferable by Company
or Holder, except for such permitted transfers to successors in interest and in
accordance with Section 5 herein, and any attempt to assign or transfer the
rights hereunder shall be void and of no further effect.

          (d) This Warrant and the other documents delivered pursuant hereto,
including without limitation the Series C Transaction Documents, constitute the
full and entire understanding and agreement between the parties with regard to
the subjects hereof and thereof.

          (e) The Company shall not, by amendment of its Amended and Restated
Articles of Incorporation, or through any other means, directly or indirectly,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant and shall at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the holder of this Warrant against
impairment.

          (f) Upon receipt of evidence reasonably satisfactory to the Company of
the loss, theft, destruction or mutilation of this Warrant and, in the case of
any such loss, theft or destruction, upon delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of any
such mutilation, upon surrender and cancellation of such Warrant, the Company at
its expense will execute and deliver to the holder of record, in lieu thereof, a
new Warrant of like date and tenor.

                                       9

                      INVESTMENT REPRESENTATION STATEMENT


PURCHASER    :  COMDISCO, INC.

COMPANY      :  2BRIDGE SOFTWARE

SECURITY     :  SERIES C PREFERRED STOCK ISSUED UPON EXERCISE OF THE SERIES C
                PREFERRED STOCK PURCHASE WARRANT ISSUED ON July 29, 1999

AMOUNT       :  _______________ SHARES

DATE         :  ___________________, ______

In connection with the purchase of the above-listed Securities, I, the
Purchaser, represent to the Company the following:

     (a) I am aware of the Company's business affairs and financial condition,
and have acquired sufficient information about the Company to reach an informed
and knowledgeable decision to acquire the Securities.  I am purchasing these
Securities for my own account for investment purposes only and not with a view
to, or for the resale in connection with, any "distribution" thereof for
purposes of the Securities Act of 1933, as amended (the "Securities Act") except
pursuant to a registration of exemption.

     (b) I understand that the Securities have not been registered under the
Securities Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of my investment intent
as expressed herein.  In this connection, I understand that, in the view of the
Securities and Exchange Commission (the "SEC"), the statutory basis for such
exemption may be unavailable if my representation was predicated solely upon a
present intention to hold these Securities for the minimum capital gains period
specified under tax statutes, for a deferred sale, for or until an increase or
decrease in the market price of the Securities, or for a period of one year or
any other fixed period in the future.

     (c) I further understand that the Securities must be held indefinitely
unless subsequently registered under the Securities Act or unless an exemption
from registration is otherwise available. Moreover, I understand that the
Company is under no obligation to register the Securities.  In addition, I
understand that the certificate evidencing the Securities will be imprinted with
a legend which prohibits the transfer of the Securities unless they are
registered or such registration is not required in the opinion of counsel for
the Company.

     (d) I am familiar with the provisions of Rule 144, promulgated under the
Securities Act, which, in substance, permits limited public resale of
"restricted securities" acquired, directly or
<PAGE>

indirectly, from the issuer thereof, in a non-public offering subject to the
satisfaction of certain conditions.

     The Securities may be resold in certain limited circumstances subject to
the provisions of Rule 144, which requires among other things: (1) the
availability of certain public information about the Company, (2) the resale
occurring not less than one year, and in some circumstances two years, after the
party has held, within the meaning of Rule 144, the securities to be sold; and,
in the case of an affiliate, or of a non-affiliate who has held the securities
less than two years, and in some circumstances three years, (3) the sale being
made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker (as said term is defined under the
Securities Exchange Act of 1934) and the amount of securities being sold during
any three month period not exceeding the specified limitations stated therein,
if applicable.

     (e) I agree, in connection with the Company's initial underwritten public
offering of the Company's securities, (1) not to sell, make 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 me (other than those shares included in the
registration) without the prior written consent of the Company or the
underwriters managing such initial underwritten public offering of the Company's
securities for one hundred eighty (180) days from the effective date of such
registration, and (2) I further agree to execute any agreement reflecting (1)
above as may be requested by the underwriters at the time of the public
offering; provided however that the officers and directors of the Company who
          -------- -------
own the stock of the Company also agree to such restrictions.

     (f) I further understand that in the event all of the applicable
requirements of Rule 144 are not satisfied, registration under the Securities
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive, the
Staff of the SEC has expressed its opinion that persons proposing to sell
private placement securities other than in a registered offering and otherwise
than pursuant to Rule 144 will have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or
sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk.

                               2BRIDGE SOFTWARE

         WARRANT TO PURCHASE 11,722 SHARES OF SERIES C PREFERRED STOCK

                                 ____________

     THIS CERTIFIES THAT, for value received, Comdisco, Inc. (the "Holder") is
entitled to subscribe for and purchase from 2Bridge Software, a California
corporation (the "Company"), shares of the Company's fully paid and
nonassessable Series C Preferred Stock (the "Shares"), in the amounts and at the
price per share set forth in Section 1 below (as adjusted pursuant to Section 4
hereof), subject to the provisions and upon the terms and conditions hereinafter
set forth.

     This Warrant is subject to the following terms and conditions:

     1.   Number and Price of Shares.
          --------------------------

          (a)  The Holder shall have the right to purchase 11,722 Shares, which
is equal to one hundred twenty-five thousand dollars ($25,000) divided by the
Exercise Price, as defined in Section 1(b) below.

          (b)  The exercise price per Share ("Exercise Price") shall be equal to
$2.1328 per Share.
<PAGE>

     2.   Method of Exercise; Payment.
          ---------------------------

          (a)  Cash Exercise.  The purchase rights represented by this Warrant
               -------------
may be exercised by the Holder, in whole or in part, from time to time by: (i)
the surrender of this Warrant (with the notice of exercise form (the "Notice of
Exercise") attached hereto as Exhibit A duly executed) at the principal office
                              ---------
of the Company; (ii) the execution of a Series C Preferred Stock Purchase
Agreement and all exhibits thereto, including without limitation an Amended and
Restated Investor Rights Agreement, Voting Agreement, and Co-Sale Agreement
(collectively, the "Series C Transaction Documents"); and (iii) by the payment
to the Company of an amount equal to the Exercise Price multiplied by the number
of the Shares being purchased, which amount may be paid, at the election of the
Holder, by wire transfer or certified check payable to the order of the Company.
The person or persons in whose name(s) any certificate(s) representing Shares
shall be issuable upon exercise of this Warrant shall be deemed to have become
the holder(s) of record of, and shall be treated for all purposes as the record
holder(s) of, the Shares represented thereby (and such Shares shall be deemed to
have been issued) immediately prior to the close of business on the date or
dates upon which this Warrant is exercised.

          (b)  Net Issue Exercise.  In lieu of exercising this Warrant
               ------------------
pursuant to Section 2(a) hereof, the Holder may elect to receive a number of
Shares equal to the value (as determined below) of this Warrant (or the portion
thereof being canceled) by surrender of this Warrant and the fully executed
Series C Transaction Documents at the principal office of the Company, together
with the Notice of Exercise in which alternative No. 1 is initiated by the
Holder. In such event, the Company shall issue to the Holder a number of Shares
computed using the following formula:

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

     Where  X = the number of Shares to be issued to the Holder.

            Y = the number of Shares subject to this warrant.

            A = the fair market value of one share of the Company's Series C
                Preferred Stock.

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

          (c)  Fair Market Value.  For purposes of this Section 2, the fair
               -----------------
market value of the Company's Series C Preferred Stock shall mean:

               (i)    The average of the closing bid and asked prices of the
Company's Common Stock quoted in the Over-The-Counter Market Summary or the
closing price quoted on any exchange on which the Common Stock is listed,
whichever is applicable, as published in the Western Edition of The Wall Street
                                                                ---------------
Journal for the ten trading days prior to the date of determination of fair
- -------
market value multiplied by the number of shares of Common Stock into which each
share of Series B Preferred Stock is convertible;

                                      -2-
<PAGE>

               (ii)   If the Company's Common Stock is not traded Over-The-
Counter or on an exchange, the fair market value of the Series C Preferred Stock
per share shall be the price per share which the Company could obtain from a
willing buyer for shares sold by the Company from authorized but unissued shares
of Series C Preferred Stock as such price shall be agreed by the parties hereto,
or if agreement cannot be reached within five (5) business days of delivery of
the notice pursuant to Section 2(b) hereof, as shall be determined by a panel of
appraisers. One appraiser shall be selected by the Holder, one appraiser shall
be chosen by the Company and the third appraiser shall be chosen by the first
two appraisers. If the appraisers cannot reach agreement as to the fair market
value on the foregoing basis on or before the thirtieth (30th) day following the
Holder's notice of election pursuant to Section 2(b), then each appraiser shall
deliver its appraisal and the appraisal which is neither the highest nor the
lowest shall be the fair market value of a share of Series C Preferred Stock. In
the event that the Holder fails to choose an appraiser or the three appraisers
fail to deliver an appraisal on or before the thirtieth (30th) day after such
notice, the appraisal of the appraiser selected by the Company shall control and
shall be fair market value for the purposes of this Warrant. The cost of the
appraiser selected by each party shall be borne by that party and the cost of
the third appraiser shall be borne one-half (1/2) by each party. Appraisers
selected under this Section 2(c) must be unaffiliated with the Holder and the
Company and must have reasonable professional qualifications for the appraisal.

          (d)  Stock Certificates.  In the event of any exercise of the rights
               ------------------
represented by this Warrant, certificates for the Shares so purchased shall be
delivered to the Holder within a reasonable time and, unless this Warrant has
been fully exercised or has expired, a new Warrant representing the Shares with
respect to which this Warrant shall not have been exercised shall also be issued
to the Holder within such time.

          (e)  Condition of Exercise  Unless exercised pursuant to an effective
               ---------------------
registration statement under the Act which includes the Shares so exercised, it
shall be a condition to any exercise of this Warrant that the Company shall have
received, at the time of such exercise, a representation in writing from the
Holder in the form attached hereto as Exhibit A-1, that the Shares being issued
                                      -----------
upon exercise are being acquired for investment and not with a view to any sale
or distribution thereof.

     3.   Stock Fully Paid; Reservation of Shares.  All of the Shares issuable
          ---------------------------------------
upon the exercise of the rights represented by this Warrant will, upon issuance
and receipt of the Exercise Price therefor, be fully paid and nonassessable, and
free from all preemptive rights, rights of first refusal or first offer, taxes,
liens and charges with respect to the issuance thereof. During the period within
which the rights represented by this Warrant may be exercised, the Company shall
at all times have authorized and reserved for issuance sufficient shares of its
Series C Preferred Stock and Common Stock to provide for the exercise of the
rights represented by this Warrant.

     4.   Adjustment of Exercise Price and Number of Shares.  The number and
          -------------------------------------------------
kind of Shares purchasable upon the exercise of this Warrant and the Exercise
Price therefor shall be subject to adjustment from time to time upon the
occurrence of certain events, as follows:

          (a)  Stock Splits, Dividends and Combinations.  In the event that the
               ----------------------------------------
Company shall at any time subdivide the outstanding shares of Series C Preferred
Stock, or shall issue a stock

                                      -3-
<PAGE>

dividend on its outstanding shares of Series C Preferred Stock, the number of
Shares issuable upon exercise of this Warrant immediately prior to such
subdivision or to the issuance of such stock dividend shall be proportionately
increased, and the Exercise Price shall be proportionately decreased, and in the
event that the Company shall at any time combine the outstanding shares of
Series C Preferred Stock, the number of Shares issuable upon exercise of this
Warrant immediately prior to such combination shall be proportionately
decreased, and the Exercise Price shall be proportionately increased, effective
at the close of business on the date of such subdivision, stock dividend or
combination, as the case may be.

          (b)  Price Adjustments.  If at any time the Company issues or sells
               -----------------
any shares of its Preferred Stock for a consideration per share less than the
then effective Exercise Price, then and in each such case, the Exercise Price
for the Shares will be reduced to a price (calculated to the nearest cent)
determined by multiplying such applicable Exercise Price by a fraction (a) the
numerator of which will be the number of shares of Preferred Stock outstanding
(or so deemed) immediately prior to such issuance or sale plus the number of
shares of Series C Preferred Stock which the aggregate consideration received by
the Company for such issuance or sale would purchase at such applicable Exercise
Price, and (b) the denominator of which will be the number of shares of
Preferred Stock outstanding (or so deemed) immediately after the Preferred Stock
proposed to be issued or sold is issued or sold; provided that such fraction
will in no event be greater than one (1). For purposes of this Section 4(b), the
Shares will be deemed to be outstanding on the date hereof.

     For the purpose of making any adjustment in the Exercise Price as provided
above, the consideration received by the Company for any issuance or sale of
Preferred Stock will be computed:

               (A)  to the extent it consists of cash, as the amount of cash
received by the Company before deduction of any offering expenses payable by the
Company and any underwriting or similar commissions, compensation, or
concessions paid or allowed by the Company in connection with such issuance or
sale;

               (B)  to the extent it consists of property other than cash, at
the fair market value of that property as determined in good faith by the
Company's Board of Directors; and

               (C)  if Preferred Stock is issued or sold together with other
stock or securities or other assets of the Company for a consideration which
covers both, as the portion of the consideration so received that may be
reasonably determined in good faith by the Board of Directors to be allocable to
such Preferred Stock.

     No adjustment to the Exercise Price pursuant to this Section 4(b) shall
affect the number of Warrants to be issued pursuant to Section 1(a) herein.

          (c)  Recapitalizations.  If at any time or from time to time there
               -----------------
shall be a recapitalization of the Series C Preferred Stock (other than a
subdivision, combination or merger or sale of assets transaction provided for
elsewhere in this Section 4), provision shall be made so that the Holder of this
Warrant will thereafter be entitled to receive upon exercise of this Warrant the
number of shares of stock or other securities or property of the Company to
which a Holder of Series B

                                      -4-
<PAGE>

Preferred Stock would have been entitled on such recapitalization. In any such
case, appropriate adjustment shall be made in the application of the provisions
of this Section 4 with respect to the rights of the Holder of this Warrant after
the recapitalization to the end that the provisions of this Section 4 (including
adjustment of the Exercise Price then in effect and the number of shares
issuable upon exercise of this Warrant) shall be applicable after that event in
as nearly an equivalent manner as may be practicable.

          (d)  Merger.  If at any time there shall be a capital reorganization
               ------
of the shares of the Company's stock (other than a combination,
reclassification, exchange or subdivision of shares otherwise provided for
herein), or a merger or consolidation of the Company with or into another
corporation, whether or not the Company is the surviving corporation, other than
as provided for in Section 10(a) herein (a "Merger Event"), then as a part of
such Merger Event, lawful provision shall be made so that the Holder shall
thereafter be entitled to receive, upon exercise of the Warrant, the number of
shares of stock or other securities of the successor corporation resulting from
such Merger Event, equivalent in value to that which would have been issuable if
Holder had exercised this Warrant immediately prior to the Merger Event. In any
such case, appropriate adjustment (as determined in good faith by the Company's
Board of Directors) shall be made in the application of the provisions of this
Warrant with respect to the rights and interest of the Holder after the Merger
Event to the end that the provisions of this Warrant (including adjustments of
the Exercise Price and number of Shares purchasable) shall be applicable to the
greatest extent possible.

          (e)  Notices.  Upon any adjustment of the Exercise Price and any
               -------
increase or decrease in the number of Shares purchasable upon the exercise of
this Warrant in accordance with Section 3 hereof, then, and in each such case,
the Company, within thirty (30) days thereafter, shall give written notice
thereof to the Holder at the address of such Holder as shown on the books of the
Company which notice shall state the Exercise Price as adjusted and, if
applicable, the increased or decreased number of Shares purchasable upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation of each. Any written notice by the Company required or permitted
hereunder shall be given by hand delivery or first class mail, postage prepaid,
addressed to the Holder at the address shown on the books of the Company for the
Holder.

     5.   Restrictions on Transfer.
          ------------------------

          (a)  Holder agrees not to make any disposition of all or any portion
of the Shares or the Warrant unless and until:

                (i)   There is then in effect a registration statement under the
1933 Act covering such proposed disposition and such disposition is made in
accordance with such registration statement; or

                (ii)  Holder shall have notified the Company of the proposed
disposition and shall have furnished the Company with a detailed statement of
the circumstances surrounding the proposed disposition, and the transferee has
agreed in writing to be bound by this Section 5. If reasonably requested by the
Company, Holder shall furnish the Company with an opinion of counsel, reasonably
satisfactory to the Company, that such disposition will not require registration
of such

                                      -5-
<PAGE>

shares under the 1933 Act. Notwithstanding the foregoing, the restrictions
imposed upon the transferability of any of the Shares or rights to acquire
Shares do not apply to transfers from the beneficial owner of any of the
aforementioned securities to its nominee or from such nominee to its beneficial
owners, and shall terminate as to any particular Shares when a letter shall have
been issued to Holder at its request by the staff of the Securities and Exchange
Commission or a ruling shall have been issued to the Holder at its request by
such Commission stating that no action shall be recommended by such staff or
taken by such Commission, as the case may be, if such security is transferred
without registration under the 1933 Act in accordance with the conditions set
forth in such letter or ruling and such letter or ruling specifies that no
subsequent restrictions on transfer are required. It is agreed that the Company
will not require opinions of counsel for transactions made pursuant to Rule 144
except in unusual circumstances.

          (b)  Notwithstanding the above, the Shares shall also be subject to
all restrictions on transfer set forth in the Series C Transaction Documents,
including without limitation a 180 day market standoff period upon the Company's
initial public offering.

     6.   Fractional Shares.  No fractional shares of Common Stock will be
          -----------------
issued in connection with any exercise hereunder, but in lieu of such fractional
shares the Company shall make a cash payment therefor upon the basis of the
Exercise Price then in effect.

     7.   Representations and Warranties by the Company.
          ---------------------------------------------

          (a)  Due Authority.  The execution and delivery by the Company of this
               -------------
Warrant and the performance of all obligations of the Company hereunder,
including the issuance to Holder of the right to acquire Shares, have been duly
authorized by all necessary corporate action on the part of the Company. This
Warrant is consistent with the Company's Amended and Restated Articles of
Incorporation, and does not contravene any law or governmental rule, regulation
or order applicable to it, and does not and will not contravene any provision
of, or constitute a default under, any indenture, mortgage, contract or other
instrument to which it is a party or by which it is bound. This Warrant
constitutes a legal, valid and binding agreement of the Company, enforceable in
accordance with its respective terms.

          (b)  Consents and Approvals.  No consent or approval of, giving of
               ----------------------
notice to, registration with, or taking of any other action in respect of any
state, Federal or other governmental authority or agency is required with
respect to the execution, delivery and performance by the Company of its
obligations under this Warrant, except for the filing of notices pursuant to
Regulation D under the 1933 Act and any filing required by applicable state
securities law, which filings shall be made by the time required thereby.

          (c)  Holder's Additional Rights.  The Series C Preferred Stock shall
               --------------------------
have anti-dilution rights, registration rights, and information rights
substantially similar to those rights given to holders of the Company's Series C
Preferred Stock, which rights shall be set forth in the Series C Transaction
Documents.

                                      -6-
<PAGE>

          (d)  Other Commitments to Register Securities.  Except as set forth
               ----------------------------------------
(i) herein, (ii) in the Investor Rights Agreement dated as of January 17, 1997,
(iii) the Warrants issued to Holder as of November 20, 1997, March 11, 1998,
July 23, 1999, and the date hereof, and (iv) the warrant issued to Imperial Bank
on May 1, 1999, the Company is not, pursuant to the terms of any other agreement
currently in existence, under any obligation to register under the Securities
Act any of its presently outstanding securities or any of its securities which
may hereafter be issued.

          (e)  Exempt Transaction.  Subject to the accuracy of the Holder's
               ------------------
representations in this Section 11 and any filing necessary to obtain a state
securities law exemption, the issuance of Shares upon exercise of this Warrant
will constitute a transaction exempt from (i) the registration requirements of
Section 5 of the Securities Act, and (ii) the qualification requirements of the
applicable state securities laws.

          (f)  Compliance with Rule 144.  At the written request of Holder, who
               ------------------------
proposes to sell Warrant Shares issuable upon the exercise of this Warrant in
compliance with Rule 144 promulgated by the Securities and Exchange Commission,
the Company shall furnish to Holder, within ten (10) days after receipt of such
request, a written statement confirming the Company's compliance with the filing
requirements of the Securities and Exchange Commission as set forth in such
Rule, as such Rule may be amended from time to time.

     8.   Representations and Warranties by the Holder.  Holder represents and
          --------------------------------------------
warrants to the Company as follows:

          (a)  This Warrant is being acquired for Holder's own account, for
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Act, and the
Holder has no present intention of selling or engaging in any public
distribution thereof pursuant to a registration or exemption.

          (b)  Holder understands that the Warrant and the Shares have not been
registered under the Act by reason of their issuance in a transaction exempt
from the registration and prospectus delivery requirements of the Act pursuant
to Section 4(2) thereof, and that they must be held by Holder indefinitely, and
that Holder must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Act or is exempted from such registration. The Holder further understands that
the Shares have not been qualified under the California Securities Law of 1968
(the "California Law") by reason of their issuance in a transaction exempt from
the qualification requirements of the California Law pursuant to Section
25102(f) thereof, which exemption depends upon, among other things, the bona
fide nature of the Holder's investment intent expressed above.

          (c)  The Holder has such knowledge and experience in financial and
business matters that it is capable of evaluating the merits and risks of the
purchase of this Warrant and the Shares purchasable pursuant to the terms of
this Warrant and of protecting its interests in connection therewith.

                                      -7-
<PAGE>

          (d)  The Holder is able to bear the economic risk of the purchase of
the Shares pursuant to the terms of this Warrant.

     9.   Rights of Stockholders.  Nothing contained herein shall confer upon
          ----------------------
Holder any of the rights of a stockholder of the Company or any right to vote
for the election of directors or upon any matter submitted to stockholders at
any meeting thereof, or to give or withhold consent to any corporate action
(whether upon any recapitalization, issuance of stock, reclassification of
stock, change of par value, consolidation, merger, conveyance, or otherwise) or
to receive notice of meetings, or to receive dividends or subscription rights or
otherwise until the Warrant shall have been exercised and the Shares purchasable
upon the exercise hereof shall have become deliverable, as provided herein.

     10.  Expiration of Warrant.
          ---------------------

          (a)  This Warrant shall expire and shall no longer be exercisable as
of the earlier of:

                (i)   5:00 p.m., California local time, on October 21, 2009;

                (ii)  five (5) years after the Company's initial public offering
under the Securities Act of 1933, as amended;

                (iii) the automatic conversion of the Series C Preferred Stock
of the Company into Common Stock of the Company, according to the terms of the
Series C Transaction Documents, provided that Company provides Holder with at
least thirty (30) days notice of such automatic conversion and that it gives
Holder an option in Holder's sole discretion to either exercise the Warrant or
cause Company to replace the Warrant with a Warrant to Purchase Common Stock on
substantially the same terms as those set forth herein;

                (iv)  a consolidation or merger of the Company with or into
another corporation (other than a consolidation or merger with another
corporation in which the Company's stockholders immediately preceding such
consolidation or merger own at least 50% of the voting securities of the
successor entity following such consolidation or merger and which does not
result in any reclassification of the Shares issuable upon exercise of this
Warrant); or

                (v)   a sale of all or substantially all of the assets of the
Company.

     11.  Miscellaneous.
          -------------

          (a)  This Warrant is being delivered in the State of California and
shall be construed and enforced in accordance with and governed by the laws of
such State. The parties expressly stipulate that any litigation under this
Warrant shall be brought in the State courts of the Counties of Santa Clara or
San Francisco, California and in the United States District Court for the
Northern District of California. The parties agree to submit to the jurisdiction
and venue of those courts. Notwithstanding the foregoing, any claim or dispute
involving questions of usury law as it applies to the Warrant shall be governed
by the laws of Illinois.

                                      -8-

          (b)  The headings in this Warrant are for purposes of reference only,
and shall not limit or otherwise affect any of the terms hereof.

          (c)  The terms of this Warrant shall be binding upon and shall inure
to the benefit of any successors in interest of the Company or the Holder. This
Warrant and all rights hereunder are not assignable or transferable by Company

accordance with Section 5 herein, and any attempt to assign or transfer the
rights hereunder shall be void and of no further effect.

          (d)  This Warrant and the other documents delivered pursuant hereto,
including without limitation the Series C Transaction Documents, constitute the
full and entire understanding and agreement between the parties with regard to
the subjects hereof and thereof.

          (e)  The Company shall not, by amendment of its Amended and Restated
Articles of Incorporation, or through any other means, directly or indirectly,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant and shall at all times in good faith assist in the carrying out of all
such terms and in the taking of all such action as may be necessary or
appropriate in order to protect the rights of the holder of this Warrant against
impairment.

          (f)  Upon receipt of evidence reasonably satisfactory to the Company
of the loss, theft, destruction or mutilation of this Warrant and, in the case
of any such loss, theft or destruction, upon delivery of an indemnity agreement
reasonably satisfactory in form and amount to the Company or, in the case of any
such mutilation, upon surrender and cancellation of such Warrant, the Company at
its expense will execute and deliver to the holder of record, in lieu thereof, a
new Warrant of like date and tenor.

               INVESTMENT REPRESENTATION STATEMENT

PURCHASER:     COMDISCO, INC.

COMPANY:       2BRIDGE SOFTWARE

SECURITY:      SERIES C PREFERRED STOCK ISSUED UPON EXERCISE OF THE SERIES C
               PREFERRED STOCK PURCHASE WARRANT ISSUED ON OCTOBER 21, 1999

AMOUNT:        _______________ SHARES

DATE:          ___________________, ______

     In connection with the purchase of the above-listed Securities, I, the
Purchaser, represent to the Company the following:

     (a)  I am aware of the Company's business affairs and financial condition,
and have acquired sufficient information about the Company to reach an informed
and knowledgeable decision to acquire the Securities. I am purchasing these
Securities for my own account for investment purposes only and not with a view
to, or for the resale in connection with, any "distribution" thereof for
purposes of the Securities Act of 1933, as amended (the "Securities Act") except
pursuant to a registration of exemption.

     (b)  I understand that the Securities have not been registered under the
Securities Act in reliance upon a specific exemption therefrom, which exemption
depends upon, among other things, the bona fide nature of my investment intent
as expressed herein. In this connection, I understand that, in the view of the
Securities and Exchange Commission (the "SEC"), the statutory basis for such
exemption may be unavailable if my representation was predicated solely upon a
present intention to hold these Securities for the minimum capital gains period
specified under tax statutes, for a deferred sale, for or until an increase or
decrease in the market price of the Securities, or for a period of one year or
any other fixed period in the future.

     (c)  I further understand that the Securities must be held indefinitely
unless subsequently registered under the Securities Act or unless an exemption
from registration is otherwise available. Moreover, I understand that the
Company is under no obligation to register the Securities. In addition, I
understand that the certificate evidencing the Securities will be imprinted with
a legend which prohibits the transfer of the Securities unless they are
registered or such registration is not required in the opinion of counsel for
the Company.

     (d)  I am familiar with the provisions of Rule 144, promulgated under the
Securities Act, which, in substance, permits limited public resale of
"restricted securities" acquired, directly or indirectly, from the issuer
thereof, in a non-public offering subject to the satisfaction of certain
conditions.

                                     -12-
<PAGE>

     The Securities may be resold in certain limited circumstances subject to
the provisions of Rule 144, which requires among other things: (1) the
availability of certain public information about the Company, (2) the resale
occurring not less than one year, and in some circumstances two years, after the
party has held, within the meaning of Rule 144, the securities to be sold; and,
in the case of an affiliate, or of a non-affiliate who has held the securities
less than two years, and in some circumstances three years, (3) the sale being
made through a broker in an unsolicited "broker's transaction" or in
transactions directly with a market maker (as said term is defined under the
Securities Exchange Act of 1934) and the amount of securities being sold during
any three month period not exceeding the specified limitations stated therein,
if applicable.

     (e)  I agree, in connection with the Company's initial underwritten public
offering of the Company's securities, (1) not to sell, make 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 me (other than those shares included in the
registration) without the prior written consent of the Company or the
underwriters managing such initial underwritten public offering of the Company's
securities for one hundred eighty (180) days from the effective date of such
registration, and (2) I further agree to execute any agreement reflecting (1)
above as may be requested by the underwriters at the time of the public
offering; provided however that the officers and directors of the Company who
          -------- -------
own the stock of the Company also agree to such restrictions.

     (f)  I further understand that in the event all of the applicable
requirements of Rule 144 are not satisfied, registration under the Securities
Act, compliance with Regulation A, or some other registration exemption will be
required; and that, notwithstanding the fact that Rule 144 is not exclusive, the
Staff of the SEC has expressed its opinion that persons proposing to sell
private placement securities other than in a registered offering and otherwise
than pursuant to Rule 144 will have a substantial burden of proof in
establishing that an exemption from registration is available for such offers or
sales, and that such persons and their respective brokers who participate in
such transactions do so at their own risk.

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.

                           WARRANT TO PURCHASE STOCK

Corporation:             2Bridge, a California corporation
Number of Shares:        10% Warrant coverage
Class of Stock:          Series D Preferred
Initial Exercise Price:  See Below.
Issue Date:              November 15, 1999
Expiration Date:         November 15, 2006, unless earlier terminated

     THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00, Silicon
Valley Bank ("Holder") is entitled to purchase the number of fully paid and
nonassessable shares of the class of securities (the "Shares") of the
corporation (the "Company") at the initial exercise price per Share (the
"Warrant Price") all as set forth above and as adjusted pursuant to Article 2 of
this Warrant, subject to the provisions and upon the terms and conditions set
forth in this Warrant. The Warrant Price shall be equal to seventy percent (70%)
of the price per share at which the Company after the Issue Date first sells its
shares of capital stock in an offering in which the Company receives not less
than $1,000,000 (the "Next Round") and the Shares subject to this Warrant shall
be the class of securities sold in the Next Round. If the Next Round does not
occur on or before July 31, 2000, then, after such date, at the option of
Holder, the Shares shall be Series C Preferred Stock and the Warrant Price shall
be $2.1328. The number of Shares subject to the Warrant shall be the quotient
derived by dividing $100,000 by the Warrant Price.

     If any amount is outstanding under the Loan Agreement between the Company
and Holder dated as of the Issue Date (the "Loan Agreement") after the Maturity
Date, as defined in the Loan Agreement, Holder may purchase additional Shares
equal to the number of Shares equal to the quotient derived by dividing $39,000
by the Warrant Price, hereunder on the day after the Maturity Date, and
additional Shares equal to the number of Shares equal to the quotient derived by
dividing $39,000 by the Warrant Price, for each 45-day period (or portion
thereof) from and including the day immediately after the Maturity Date that any
amount remains outstanding under the Loan Agreement.

ARTICLE 1. EXERCISE.
           ---------

     1.1  Method of Exercise. Holder may exercise this Warrant by delivering a
          ------------------
duly executed Notice of Exercise in substantially the form attached as Appendix
I to the principal office of the Company. Unless Holder is exercising the
conversion right set forth in Section 1.2, Holder shall also deliver to the
Company a check for the aggregate Warrant Price for the Shares being purchased.

     1.2  Conversion Right. In lieu of exercising this Warrant as specified in
          ----------------
Section 1.1, Holder may from time to time convert this Warrant at any time the
fair market value of a Share exceeds the Warrant Price, in whole or in part,
into a number of Shares determined by dividing (a) the aggregate fair market
value of the Shares or other securities otherwise issuable upon exercise of this
Warrant minus the aggregate Warrant Price of such Shares by (b) the fair market
value of one Share. The fair market value of the Shares shall be determined
pursuant Section 1.4.

                                       1
<PAGE>

     1.3  No Rights as Shareholder. This Warrant does not entitle Holder to any
          ------------------------
voting rights as a shareholder of the Company prior to the exercise hereof.

     1.4  Fair Market Value. If the Shares are traded in a public market, the
          -----------------
fair market value of the Shares shall be the closing price of the Shares (or the
closing price of the Company's stock into which the Shares are convertible)
reported for the business day immediately before Holder delivers its Notice of
Exercise to the Company. If the Shares are not traded in a public market, the
Board of Directors of the Company shall determine fair market value in its
reasonable good faith judgment. The foregoing notwithstanding, if Holder advises
the Board of Directors in writing that Holder disagrees with such determination,
then the Company and Holder shall promptly agree upon a reputable investment
banking or public accounting firm to undertake such valuation. If the valuation
of such investment banking or public accounting firm is greater than that
determined by the Board of Directors, then all fees and expenses of such
investment banking or accounting firm shall be paid by the Company. In all other
circumstances, such fees and expenses shall be paid by Holder.

     1.5  Delivery of Certificate and New Warrant. Promptly after Holder
          ---------------------------------------
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.6  Replacement of Warrants. On receipt of evidence reasonably
          -----------------------
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

     1.7  Repurchase on Sale, Merger, or Consolidation of the Company.
          -----------------------------------------------------------

          1.7.1  "Acquisition". For the purpose of this Warrant, "Acquisition"
                  -----------
means any sale, license, or other disposition of all or substantially all of the
assets of the Company, or any reorganization, consolidation, or merger of the
Company where the holders of the Company's securities before the transaction
beneficially own less than 50% of the outstanding voting securities of the
surviving entity after the transaction.

          1.7.2  Assumption of Warrant. Upon the closing of any Acquisition the
                 ---------------------
successor entity may elect to assume the obligations of this Warrant, in which
case this Warrant shall be exercisable for the same securities, cash, and
property as would be payable for the Shares issuable upon exercise of the
unexercised portion of this Warrant as if such Shares were outstanding on the
record date for the Acquisition any subsequent closing. The Warrant Price shall
be adjusted accordingly. If this Warrant is not assumed, and the fair market
value of one Share is greater than the Warrant Price, it shall be deemed to have
been converted into Shares pursuant to Section 1.2 hereof immediately prior to
the consummation of the Acquisition. If this Warrant is not assumed and is not
convertible pursuant to Section 1.2, it shall terminate immediately upon
consummation of the Acquisition if Holder fails to exercise the Warrant prior to
the Acquisition.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.
           -------------------------

     2.1  Stock Dividends, Splits, Etc. If the Company declares or pays a
          ----------------------------
dividend On the Shares payable in common stock, or other securities or
subdivides the Shares in a transaction that increases the amount of common stock
into which the Shares are convertible, then upon exercise of this Warrant, for
each Share acquired, Holder shall receive, without cost to Holder, the total
number and kind of securities to which Holder would have been entitled had
Holder owned the Shares of record as of the date the dividend or subdivision
occurred.

     2.2  Reclassification, Exchange or Substitution. Subject to Section 1.7,
          ------------------------------------------
upon any reclassification, exchange, substitution, or other event that results
in a change of the number and/or class of the securities issuable upon exercise
or conversion of this Warrant, Holder shall be entitled to receive, upon
exercise or conversion of this Warrant, the number and kind of securities and
property that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event.

                                       2
<PAGE>

Subject to Section 4.1, such an event shall include any automatic conversion of
the outstanding or issuable securities of the Company of the same class or
series as the Shares to common stock pursuant to the terms of the Company's
Articles of Incorporation upon the closing of a registered public offering of
the Company's common stock. The Company or its successor shall promptly issue to
Holder a new Warrant for such new securities or other property. The new Warrant
shall provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 2 including, without
limitation, adjustments to the Warrant Price and to the number of securities or
property issuable upon exercise of the new Warrant. The provisions of this
Section 2.2 shall similarly apply to successive reclassifications, exchanges,
substitutions, or other events.

     2.3  Adjustments for Combinations Etc. If the outstanding Shares are
          --------------------------------
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased and the number
of Shares proportionately decreased.

     2.4  No Impairment. The Company shall not, by amendment of its Articles of
          -------------
Incorporation or through a reorganization, 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 under this Warrant by the Company, but shall at all times
in good faith assist in carrying out of all the provisions of this Article 2 and
in taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares other than as described above that adversely affects
Holder's rights under this Warrant, the Warrant Price shall be adjusted downward
and the number of Shares issuable upon exercise of this Warrant shall be
adjusted upward in such a manner that the aggregate Warrant Price of this
Warrant is unchanged.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.
           --------------------------------------------

     3.1  Representations and Warranties. The Company hereby represents and
          ------------------------------
warrants to the Holder that all Shares which may be issued upon the exercise of
the purchase right represented by this Warrant, and all securities, if any,

authorized, validly issued, fully paid and nonassessable, and free of any liens
and encumbrances except for restrictions on transfer provided for herein or
under applicable federal and state securities laws.

     3.2  Notice of Certain Events. If the Company proposes at any time (a) to

its stock any additional shares of stock of any class or series or other rights;

license, or convey all or substantially all of its assets, or to liquidate,
dissolve or wind up; or (e) offer holders of registration rights the opportunity
to participate in an underwritten public offering of the company's securities
for cash, then, in connection with each such event, the Company shall give
Holder (1) at least 20 days prior written notice of the date on which a record
will be taken for such dividend, distribution, or subscription rights (and
specifying the date on which the holders of common stock will be entitled
thereto) or for determining rights to vote, if any, in respect of the matters
referred to in (c) and (d) above; (2) in the case of the matters referred to in
(c) arid (d) above at least 20 days prior written notice of the date when the

property deliverable upon the occurrence of such event); and (3) in the case of
the matter referred to in (e) above, the same notice as is given to the holders
of such registration rights.

any other holders of the Company's Series C Preferred Stock

                                       3

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT REQUIRED.

                           WARRANT TO PURCHASE STOCK

Corporation:             2Bridge, a California corporation
Number of Shares:        16.3% Warrant coverage
Class of Stock:          Series D Preferred
Initial Exercise Price:  See Below.
Issue Date:              November 15, 1999
Expiration Date:         November 15, 2006, unless earlier terminated

     THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00, SAND HILL
CAPITAL II, LP ("Holder") is entitled to purchase the number Of fully paid and
nonassessable shares of the class of securities (the "Shares") of the
corporation (the "Company") at the initial exercise price per Share (the
"Warrant Price") all as set forth above and as adjusted pursuant to Article 2 of
this Warrant, subject to the provisions and upon the terms and conditions set
forth in this Warrant. The Warrant Price shall be equal to seventy percent (70%)
of the price per share at which the Company after the Issue Date first sells its
shares of capital stock in an offering in which the Company receives not less
than $1,000,000 (the "Next Round") and the Shares subject to this Warrant shall
be the class of securities sold in the Next Round. If the Next Round does not
occur on or before July 31, 2000, then, after such date, at the option of
Holder, the Shares shall be Series C Preferred Stock and the Warrant Price shall
be $2.1328. The number of Shares subject to the Warrant shall be the quotient
derived by dividing $330,260 by the Warrant Price.

     If any amount is outstanding under the Loan Agreement between the Company
and Holder dated as of the Issue Date (the "Loan Agreement") after the Maturity
Date, as defined in the Loan Agreement, Holder may purchase additional Shares
equal to the number of Shares equal to the quotient derived by dividing $108,500
by the Warrant Price, hereunder on the day after the Maturity Date, and
additional Shares equal to the number of Shares equal to the quotient derived by
dividing $108,500 by the Warrant Price, for each 45-day period (or portion
thereof) from and including the day immediately after the Maturity Date that any
amount remains outstanding under the Loan Agreement.

ARTICLE 1. EXERCISE.
           --------

     1.1  Method of Exercise. Holder may exercise this Warrant by delivering a
          ------------------
duty executed Notice of Exercise in substantially the form attached as Appendix
1 to the principal office of the Company. Unless Holder is exercising the
conversion right set forth in Section 1.2, Holder shall also deliver to the
Company a check for the aggregate Warrant Price for the Shares being purchased.

     1.2  Conversion Right. In lieu of exercising this Warrant as specified in
          ----------------
Section 1.1, Holder may from time to time convert this Warrant at any time the
fair market value of a Share exceeds the Warrant Price, in whole or in part,
into a number of Shares determined by dividing (a) the aggregate fair market
value of the Shares or other securities otherwise issuable upon exercise of this
Warrant minus the aggregate Warrant Price of such Shares by (b) the fair market
value of one Share. The fair market value of the Shares shall be determined
pursuant Section 1.4.

                                       1
<PAGE>

     1.3  No Rights as Shareholder. This Warrant does not entitle Holder to any
          ------------------------
voting rights as a shareholder of the Company prior to the exercise hereof.

     1.4  Fair Market Value. If the Shares are traded in a public market, the
          -----------------
fair market value of the Shares shall be the closing price of the Shares (or the
closing price of the Company's stock into which the Shares are convertible)
reported for the business day immediately before Holder delivers its Notice of
Exercise to the Company. If the Shares are not traded in a public market, the
Board of Directors of the Company shall determine fair market value in its
reasonable good faith judgment. The foregoing notwithstanding, if Holder advises
the Board of Directors in writing that Holder disagrees with such determination,
then the Company and Holder shall promptly agree upon a reputable investment
banking or public accounting firm to undertake such valuation. If the valuation
of such investment banking or public accounting firm is greater than that
determined by the Board of Directors, then all fees and expenses of such
investment banking or accounting firm shall be paid by the Company. In all other
circumstances, such fees and expenses shall be paid by Holder.

     1.5  Delivery of Certificate and New Warrant. Promptly after Holder
          ---------------------------------------
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.6  Replacement of Warrants. On receipt of evidence reasonably
          -----------------------
satisfactory 1o the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery Of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

     1.7  Repurchase on Sale, Merger, or Consolidation of the Company.
          -----------------------------------------------------------

          1.7.1  "Acquisition". For the purpose of this Warrant, "Acquisition"
                 -------------
means any sale, license, or other disposition of all or substantially all of the
assets of the Company, or any reorganization, consolidation, or merger of the
Company where the holders of the Company's securities before the transaction
beneficially own less than 50% of the outstanding voting securities of the
surviving entity after the transaction.

          1.7.2  Assumption of Warrant. Upon the closing of any Acquisition the
                 ---------------------
successor entity may elect to assume the obligations of this Warrant, in which
case this Warrant shall be exercisable for the same securities, cash, and
property as would be payable for the Shares issuable upon exercise of the
unexercised portion of this Warrant as if such Shares were outstanding on the
record date for the Acquisition and subsequent closing. The Warrant Price shall
be adjusted accordingly. If this Warrant is not assumed, and the fair market
value of one Share is greater than the Warrant Price, it shall be deemed to have
been converted into Shares pursuant to Section 1.2 hereof immediately prior to
the consummation of the Acquisition. If this Warrant is not assumed and is not
convertible pursuant to Section 1.2, it shall terminate immediately upon
consummation of the Acquisition if Holder fails to exercise the Warrant prior to
the Acquisition.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.
           -------------------------

     2.1  Stock Dividends, Splits, Etc. If the Company declares or pays a
          ----------------------------
dividend on the Shares payable in common stock, or other securities or
subdivides the Shares in a transaction that increases the amount of common stock
into which the Shares are convertible, then upon exercise of this Warrant, for
each Share acquired, Holder shall receive, without cost to Holder, the total
number and kind of securities to which Holder would have been entitled had
Holder owned the Shares of record as of the date the dividend or subdivision
occurred.

     2.2  Reclassification, Exchange or Substitution. Subject to Section 1.7,
          ------------------------------------------
upon any reclassification, exchange, substitution, or other event that results
in a change of the number and/or class of the securities issuable upon exercise
or conversion of this Warrant, Holder shall be entitled to receive, upon
exercise or conversion of this Warrant, the number and kind of securities and
property that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event.

                                       2
<PAGE>

Subject to Section 4.1, such an event shall include any automatic conversion of
the outstanding or issuable securities of the Company of the same class or
series as the Shares to common stock pursuant to the terms of the Company's
Articles of Incorporation upon the closing of a registered public offering of
the Company's common stock. The Company or its successor shall promptly issue to
Holder a new Warrant for such new securities or other property. The new Warrant
shall provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 2 including, without
limitation, adjustments to the Warrant Price and to the number of securities or
property issuable upon exercise of the new Warrant. The provisions of this
Section 2.2 shall similarly apply to successive reclassifications, exchanges,
substitutions, or other events.

     2.3  Adjustments for Combinations, Etc. If the outstanding Shares are
          ---------------------------------
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased and the number
of Shares proportionately decreased.

     2.4  No Impairment. The Company shall not, by amendment of its Articles of
          -------------
Incorporation or through a reorganization, 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 under this Warrant by the Company, but shall at all times
in good faith assist in carrying out of all the provisions of this Article 2 and
in taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares other than as described above that adversely affects
Holder's rights under this Warrant, the Warrant Price shall be adjusted downward
and the number of Shares issuable upon exercise of this Warrant shall be
adjusted upward in such a manner that the aggregate Warrant Price of this
Warrant is unchanged.

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

     3.1  Representations and Warranties. The Company hereby represents and

additional Shares equal to the number of Shares equal to the quotient derived by
dividing $105,000 by the Warrant Price, for each 45-day period (or portion
thereof) from and including the day immediately after the Maturity Date that any
amount remains outstanding under the Loan Agreement.

ARTICLE 1. EXERCISE.
           --------

     1.1  Method of Exercise. Holder may exercise this Warrant by delivering a
          ------------------
duly executed Notice of Exercise in substantially the form attached as Appendix
1 to the principal office of the Company. Unless Holder is exercising the
conversion right set forth in Section 1.2, Holder shall also deliver to the
Company a check for the aggregate Warrant Price for the Shares being purchased.

     1.2  Conversion Right. In lieu of exercising this Warrant as specified in
          ----------------
Section 1.1, Holder may from time to time convert this Warrant at any time the
fair market value of a Share exceeds the Warrant Price, in whole or in part,
into a number of Shares determined by dividing (a) the aggregate fair market
value of the Shares or other securities otherwise issuable upon exercise of this
Warrant minus the aggregate Warrant Price of such Shares by (b) the fair market
value of one Share. The fair market value of the Shares shall be determined
pursuant Section 1.4.

                                       1
<PAGE>

     1.3  No Rights as Shareholder. This Warrant does not entitle Holder to any
          ------------------------
voting rights as a shareholder of the Company prior to the exercise hereof.

     1.4  Fair Market Value. If the Shares are traded in a public market, the
          -----------------
fair market value of the Shares shall be the closing price of the Shares (or the
closing price of the Company's stock into which the Shares are convertible)
reported for the business day immediately before Holder delivers its Notice of
Exercise to the Company. If the Shares are not traded in a public market, the
Board of Directors of the Company shall determine fair market value in its
reasonable good faith judgment. The foregoing notwithstanding, if Holder advises
the Board of Directors in writing that Holder disagrees with such determination,
then the Company and Holder shall promptly agree upon a reputable investment
banking or public accounting firm to undertake such valuation. If the valuation
of such investment banking or public accounting firm is greater than that
determined by the Board of Directors, then all fees and expenses of such
investment banking or accounting firm shall be paid by the Company. In all other
circumstances, such fees and expenses shall be paid by Holder.

     1.5  Delivery of Certificate and New Warrant. Promptly after Holder
          ---------------------------------------
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.6  Replacement of Warrants. On receipt of evidence reasonably
          -----------------------
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

     1.7  Repurchase on Sale, Merger, or Consolidation of the Company.
          -----------------------------------------------------------

          1.7.1  "Acquisition". For the purpose of this Warrant, "Acquisition"
                  -----------
means any sale, license, or other disposition of all or substantially all of the
assets of the Company, or any reorganization, consolidation, or merger of the
Company where the holders of the Company's securities before the transaction
beneficially own less than 50% of the outstanding voting securities of the
surviving entity after the transaction.

          1.7.2  Assumption of Warrant. Upon the closing of any Acquisition the
                 ---------------------
successor entity may elect to assume the obligations of this Warrant, in which
case this Warrant shall be exercisable for the same securities, cash, and
property as would be payable for the Shares issuable upon exercise of the
unexercised portion of this Warrant as if such Shares were outstanding on the
record date for the Acquisition any subsequent closing. The Warrant Price shall
be adjusted accordingly. If this Warrant is not assumed, and the fair market
value of one Share is greater than the Warrant Price, it shall be deemed to have
been converted into Shares pursuant to Section 1.2 hereof immediately prior to
the consummation of the Acquisition. If this Warrant is not assumed and is not
convertible pursuant to Section 1.2, it shall terminate immediately upon
consummation of the Acquisition if Holder fails to exercise the Warrant prior to
the Acquisition.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.
           -------------------------

     2.1  Stock Dividends, Splits, Etc. If the Company declares or pays a
          ----------------------------
dividend on the Shares payable in common stock, or other securities or
subdivides the Shares in a transaction that increases the amount of common stock
into which the Shares are convertible, then upon exercise of this Warrant, for
each Share acquired, Holder shall receive, without cost to Holder, the total
number and kind of securities to which Holder would have been entitled had
Holder owned the Shares of record as of the date the dividend or subdivision
occurred.

     2.2  Reclassification, Exchange or Substitution. Subject to Section 1.7,
          ------------------------------------------
upon any reclassification, exchange, substitution, or other event that results
in a change of the number and/or class of the securities issuable upon exercise
or conversion of this Warrant, Holder shall be entitled to receive, upon
exercise or conversion of this Warrant, the number and kind of securities and
property that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event.

                                       2
<PAGE>

Subject to Section 4.1, such an event shall include any automatic conversion of
the outstanding or issuable securities of the Company of the same class or
series as the Shares to common stock pursuant to the terms of the Company's
Articles of Incorporation upon the closing of a registered public offering of
the Company's common stock. The Company or its successor shall promptly issue to
Holder a new Warrant for such new securities or other property. The new Warrant
shall provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 2 including, without
limitation, adjustments to the Warrant Price and to the number of securities or
property issuable upon exercise of the new Warrant. The provisions of this
Section 2.2 shall similarly apply to successive reclassifications, exchanges,
substitutions, or other events.

     2.3  Adjustments for Combinations Etc. If the outstanding Shares are
          --------------------------------
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased and the number
of Shares proportionately decreased.

     2.4  No Impairment. The Company shall not, by amendment of its Articles of
          -------------
Incorporation or through a reorganization, 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 under this Warrant by the Company, but shall at all times
in good faith assist in carrying out of all the provisions of this Article 2 and
in taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any action
affecting the Shares other than as described above that adversely affects
Holder's rights under this Warrant, the Warrant Price shall be adjusted downward
and the number of Shares issuable upon exercise of this Warrant shall be
adjusted upward in such a manner that the aggregate Warrant Price of this
Warrant is unchanged.

ARTICLE 3. REPRESENTATIONS AND COVENANTS OF THE COMPANY.
           --------------------------------------------

     3.1  Representations and Warranties. The Company hereby represents and
          ------------------------------

                                    2BRIDGE

                      RESTRICTED STOCK PURCHASE AGREEMENT

     THIS AGREEMENT is made as of, March 8, 2000, between 2Bridge, a
California corporation (the "Company") and Milton Berlinksi (the "Purchaser").

     WHEREAS the Purchaser is a director of the Company and the Purchaser's
participation is considered by the Company to be important for the Company's
growth; and

     WHEREAS in order to give the Purchaser an opportunity to acquire an
equity interest in the Company as an incentive for the Purchaser to participate
in the affairs of the Company, the Company is willing to sell to the Purchaser
and the Purchaser desires to purchase shares of Common Stock of the Company
according to the terms and conditions contained herein.

     THEREFORE, the parties agree as follows:

     1.   Sale of Stock.  The Company hereby agrees to sell to the Purchaser and
          -------------
the Purchaser hereby agrees to purchase an aggregate of 400,000 shares of the
Company's Common Stock (the "Shares"), at the price of $3.50 per share for an
aggregate purchase price of $1,400,000.

     2.   Closing.  The purchase and sale of the Shares shall be made in one or
          -------
more closings, the first of which will take place at 10:00 a.m. on March 8,
2000, at the offices of Wilson Sonsini Goodrich & Rosati, 650 Page Mill Road,
Palo Alto, California, or such other place and/or other date or dates as the
Company and the Purchaser mutually agree (which time and place are designated
the "Closing").  At the Closing, the Company will deliver to the Purchaser a
certificate representing the Shares which the Purchaser is purchasing against
delivery to the Company by the Purchaser of the applicable purchase price set
forth in Section 1 herein.

     3.   Stop-Transfer Notices.  (a) Purchaser agrees that, in order to ensure
          ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

               (b)  The Company shall not be required (i) to transfer on its
books any Shares that have been sold or otherwise transferred in violation of
any of the provisions of this Agreement or (ii) to treat as owner of such Shares
or to accord the right to vote or pay dividends to any purchaser or other
transferee to whom such Shares shall have been so transferred.

     4.   Purchaser Representations.  In connection with the purchase of the
          -------------------------
Shares, the Purchaser represents to the Company the following:

               (a) Investment Intent; Capacity to Protect Interests.
                   ------------------------------------------------
<PAGE>

          (i)   The Purchaser is acquiring the Shares solely for his own account
for investment and not with a view to or for sale in connection with any
distribution of the Shares or any portion thereof and not with any present
intention of selling, offering to sell or otherwise disposing of or distributing
the Shares or any portion thereof in any transaction other than a transaction
exempt from registration under the Securities Act of 1933, as amended (the
"Act").  The Purchaser also represents that the entire legal and beneficial
interest of the Shares is being acquired by, and will be held for, the
Purchaser's account only, and neither in whole or in part for any other person.

          (ii)  The Purchaser either has a pre-existing business or personal
relationship with the Company or any of its officers, directors or controlling
persons or by reason of the Purchaser's business or financial experience, or the
business or financial experience of the Purchaser's professional advisors who
are unaffiliated with and who are not compensated by the Company or any
affiliate or selling agent of the Company, directly or indirectly, could be
reasonably assumed to have the capacity to evaluate the merits and risks of an
investment in the Company and to protect the Purchaser's own interests in
connection with this transaction.

          (iii) The Purchaser represents that he is an "accredited investor"
under the Act and has such knowledge and experience in financial and business
matters as to be capable of evaluating the merits and risks of the Purchaser's
prospective investment in the Company.

     (b) Economic Risk.  The Purchaser realizes that the acquisition of the
         -------------
Shares will be a highly speculative investment and involves a high degree of
risk, and the Purchaser is able, without significantly impairing his financial
condition, to hold the Shares for an indefinite period of time and to suffer a
complete loss of the Purchaser's investment.

     (c) Restricted Securities.  The Purchaser understands and acknowledges
         ---------------------
that:

          (i)   the Shares have not been registered under the Act, and the
Shares must be held indefinitely unless subsequently registered under the Act or
an exemption from such registration is available (such as Rule 144);

          (ii)  the share certificate representing the Shares will be stamped
with the legends specified in paragraph 6 hereof; and

          (iii) the Company will make a notation in its records of the
aforementioned restrictions on transfer and legends.

     (d) Disposition under the Act. The Purchaser understands that the Shares
         -------------------------
are restricted securities within the meaning of Rule 144 promulgated under the
Act; that the exemption from registration under Rule 144 will not be available
in any event for at least one year after the later of the date the Shares were
sold by the Company or the date the Shares were sold by an affiliate of the
Company, within the meaning of Rule 144, and even then will not be available
unless adequate information concerning the Company is then available to the
public and other terms and conditions of Rule 144 are complied with; and that
any sale of the Shares may be made only in limited amounts

                                      -2-
<PAGE>

in accordance with such terms and conditions. There can be no assurance that the
requirements of Rule 144 will be met, or that the Shares will ever be saleable.

          (e) Further Limitations on Disposition.  Without in any way limiting
              ----------------------------------
his representations set forth above, the Purchaser further agrees that the
Purchaser shall in no event make any disposition of all or any portion of the
Shares unless and until (i) there is then in effect a Registration Statement
under the Act covering such proposed disposition and such disposition is made in
accordance with said Registration Statement, (ii) the resale provisions of Rule
144(k) are available in the opinion of counsel to the Company or (iii) (A) the
Purchaser shall have notified the Company of the proposed disposition and shall
have furnished the Company with a detailed statement of the circumstances
surrounding the proposed disposition, (B) the Purchaser shall have furnished the
Company with an opinion of the Purchaser's counsel to the effect that such
disposition will not require registration of such stock under the Act and (C)
such opinion of the Purchaser's counsel shall have been concurred in by counsel
for the Company, and the Company shall have advised the Purchaser of such
concurrence.

     5.   Company Representations.  In connection with its sale of the Shares,
          -----------------------
the Company hereby represents and warrants to the Purchaser the following:

          (a) Corporate Organization and Authority.  The Company: (i) is a
              ------------------------------------
corporation duly organized, validly existing, authorized to exercise all its
corporate powers, rights and privileges, and in good standing in the State of
California, and (ii) has the corporate power and authority to (A) own and
operate its properties, (B) carry on its business as now conducted and as
proposed to be conducted, (C) execute and deliver this Agreement, (D) issue and
sell the Shares hereunder, (E) carry out the provisions of this Agreement.

          (b) Authorization.  All action on the part of the Company, its
              -------------
officers, directors and shareholders necessary for the authorization, execution,
delivery and performance of all obligations under this Agreement and for the
authorization, sale, issuance and delivery of the Shares has been taken. When
executed and delivered, this Agreement will constitute a legally valid and
binding obligation of the Company enforceable against the Company in accordance
with its terms, except to the extent that such enforcement may be subject to
applicable federal or state bankruptcy, insolvency, reorganization, arrangement,
moratorium, fraudulent conveyance or other laws or court decisions relating to

                                    2BRIDGE
                      RESTRICTED STOCK PURCHASE AGREEMENT

     THIS AGREEMENT is made as of, March 8, 2000, between 2Bridge, a
California corporation (the "Company") and David Braunschvig (the "Purchaser").

     WHEREAS the Purchaser is a director of the Company and the Purchaser's
participation is considered by the Company to be important for the Company's
growth; and

     WHEREAS in order to give the Purchaser an opportunity to acquire an
equity interest in the Company as an incentive for the Purchaser to participate
in the affairs of the Company, the Company is willing to sell to the Purchaser
and the Purchaser desires to purchase shares of Common Stock of the Company
according to the terms and conditions contained herein.

     THEREFORE, the parties agree as follows:

     1.   Sale of Stock.  The Company hereby agrees to sell to the Purchaser and
          -------------
the Purchaser hereby agrees to purchase an aggregate of 50,000 shares of the
Company's Common Stock (the "Shares"), at the price of $3.50 per share for an
aggregate purchase price of $175,000.

     2.   Closing.  The purchase and sale of the Shares shall be made in one or
          -------
more closings, the first of which will take place at 10:00 a.m. on March 8,
2000, at the offices of Wilson Sonsini Goodrich & Rosati, 650 Page Mill Road,
Palo Alto, California, or such other place and/or other date or dates as the
Company and the Purchaser mutually agree (which time and place are designated
the "Closing").  At the Closing, the Company will deliver to the Purchaser a
certificate representing the Shares which the Purchaser is purchasing against
delivery to the Company by the Purchaser of the applicable purchase price set
forth in Section 1 herein.

     3.   Stop-Transfer Notices.  (a) Purchaser agrees that, in order to ensure
          ---------------------
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (b) The Company shall not be required (i) to transfer on its books any
Shares that have been sold or otherwise transferred in violation of any of the
provisions of this Agreement or (ii) to treat as owner of such Shares or to
accord the right to vote or pay dividends to any purchaser or other transferee
to whom such Shares shall have been so transferred.

     4.   Purchaser Representations.  In connection with the purchase of the
          -------------------------
Shares, the Purchaser represents to the Company the following:

          (a) Investment Intent; Capacity to Protect Interests.
              ------------------------------------------------
<PAGE>

               (i)    The Purchaser is acquiring the Shares solely for his own
account for investment and not with a view to or for sale in connection with any
distribution of the Shares or any portion thereof and not with any present
intention of selling, offering to sell or otherwise disposing of or distributing
the Shares or any portion thereof in any transaction other than a transaction
exempt from registration under the Securities Act of 1933, as amended (the
"Act"). The Purchaser also represents that the entire legal and beneficial
interest of the Shares is being acquired by, and will be held for, the
Purchaser's account only, and neither in whole or in part for any other person.

               (ii)   The Purchaser either has a pre-existing business or
personal relationship with the Company or any of its officers, directors or
controlling persons or by reason of the Purchaser's business or financial
experience, or the business or financial experience of the Purchaser's
professional advisors who are unaffiliated with and who are not compensated by
the Company or any affiliate or selling agent of the Company, directly or
indirectly, could be reasonably assumed to have the capacity to evaluate the
merits and risks of an investment in the Company and to protect the Purchaser's
own interests in connection with this transaction.

               (iii)  The Purchaser represents that he is an "accredited
investor" under the Act and has such knowledge and experience in financial and
business matters as to be capable of evaluating the merits and risks of the
Purchaser's prospective investment in the Company.

          (b)  Economic Risk. The Purchaser realizes that the acquisition of the
               -------------
Shares will be a highly speculative investment and involves a high degree of
risk, and the Purchaser is able, without significantly impairing his financial
condition, to hold the Shares for an indefinite period of time and to suffer a
complete loss of the Purchaser's investment.

          (c)  Restricted Securities. The Purchaser understands and acknowledges
               ---------------------
that:

               (i)    the Shares have not been registered under the Act, and the
Shares must be held indefinitely unless subsequently registered under the Act or
an exemption from such registration is available (such as Rule 144);

               (ii)   the share certificate representing the Shares will be
stamped with the legends specified in paragraph 6 hereof; and

               (iii)  the Company will make a notation in its records of the
aforementioned restrictions on transfer and legends.

          (d)  Disposition under the Act. The Purchaser understands that the
               -------------------------
Shares are restricted securities within the meaning of Rule 144 promulgated
under the Act; that the exemption from registration under Rule 144 will not be
available in any event for at least one year after the later of the date the
Shares were sold by the Company or the date the Shares were sold by an affiliate
of the Company, within the meaning of Rule 144, and even then will not be
available unless adequate information concerning the Company is then available
to the public and other terms and conditions

                                      -2-
<PAGE>

of Rule 144 are complied with; and that any sale of the Shares may be made only
in limited amounts in accordance with such terms and conditions. There can be no
assurance that the requirements of Rule 144 will be met, or that the Shares will
ever be saleable.

          (e)  Further Limitations on Disposition. Without in any way limiting
               ----------------------------------
his representations set forth above, the Purchaser further agrees that the
Purchaser shall in no event make any disposition of all or any portion of the
Shares unless and until (i) there is then in effect a Registration Statement
under the Act covering such proposed disposition and such disposition is made in
accordance with said Registration Statement, (ii) the resale provisions of Rule
144(k) are available in the opinion of counsel to the Company or (iii) (A) the
Purchaser shall have notified the Company of the proposed disposition and shall
have furnished the Company with a detailed statement of the circumstances
surrounding the proposed disposition, (B) the Purchaser shall have furnished the
Company with an opinion of the Purchaser's counsel to the effect that such
disposition will not require registration of such stock under the Act and (C)
such opinion of the Purchaser's counsel shall have been concurred in by counsel
for the Company, and the Company shall have advised the Purchaser of such
concurrence.
