ENTIRETY BY, THE MORE DETAILED INFORMATION AND FINANCIAL STATEMENTS AND THE
NOTES TO THOSE STATEMENTS APPEARING ELSEWHERE IN THIS PROSPECTUS. EXCEPT AS
OTHERWISE NOTED, ALL INFORMATION IN THIS PROSPECTUS: (1) REFLECTS THE AUTOMATIC
CONVERSION OF OUR OUTSTANDING SERIES A, SERIES B, SERIES C AND SERIES D

                                 NETZERO, INC.

    NetZero is pioneering a new Internet service model that provides consumers
with free and easy access to the Internet while offering online advertisers a
highly effective way to target those users. We offer users a simple and
compelling proposition--free and unlimited Internet access as well as free
e-mail and navigational tools to enhance their online experience. For
advertisers, our service offers a powerful online direct marketing tool with
features and functionality that have distinct advantages over traditional forms
of online advertising. The value of NetZero's proposition is evidenced by our
growth; between our October 1998 launch and June 30, 1999, approximately 1.17
million users registered for our service. During June 1999, approximately
613,000 of these users accessed our service and were delivered over 830 million
advertising impressions. Our services are offered in over 1,100 cities
nationwide.

    An important feature of our service is The ZeroPort, a small window
displayed on our users' computer screens while they are online that is always
visible regardless of where they navigate. Users can move The ZeroPort to any
location on their screen but cannot close it or reduce its size. The ZeroPort
displays advertisements and advertiser-sponsored buttons and icons, all of which
can link directly to sites and services such as news, financial information,
sports and shopping. We generate revenues by selling advertisements and
sponsorships on The ZeroPort and by referring our users to sponsors' Web-sites.
We plan to receive fees from advertisers when our users subscribe for services
or purchase products or when other performance criteria are satisfied.

    While the Internet has emerged as an attractive new advertising medium,
advertisers are seeking solutions to enhance its effectiveness for targeting
users and delivering messages. Most online advertisers have difficulties
successfully targeting their audiences, largely due to a lack of precise data on
user demographics and online behavior. Online advertisers also face challenges
capturing the attention of users and delivering messages for a sustained period
of time as they can with television and radio. We obtain demographic information
from our users and track their online activity, enabling us to offer advertisers
the ability to target users, measure advertising effectiveness and potentially
improve the return on their advertising dollars. Moreover, in contrast to
traditional online advertisements which can generally be scrolled off of a
viewer's screen, The ZeroPort is always visible during a user's online session,
enabling our advertisers to display messages for a sustained period of time. We
believe NetZero offers solutions that enhance the effectiveness of online
advertising and can redefine the way products and services are marketed online.

    We were incorporated in California in July 1997 and plan to reincorporate in
Delaware prior to completion of the offering. Our executive offices are located
at 2555 Townsgate Road, Westlake Village, California 91361, and our telephone
number is (805) 418-2000. Information contained on our Web-site or The ZeroPort
does not constitute part of this prospectus. NetZero-TM-, The ZeroPort-TM-,
zCast-TM- and SPEEDY Assistant-TM- are our trademarks. This prospectus also
includes trademarks of entities other than NetZero.

ONLY ONES WE FACE. ADDITIONAL RISKS AND UNCERTAINTIES NOT PRESENTLY KNOWN TO US
OR THAT WE CURRENTLY DEEM IMMATERIAL MAY ALSO IMPAIR OUR BUSINESS OPERATIONS.

    IF ANY OF THE FOLLOWING RISKS ACTUALLY OCCUR, OUR BUSINESS, RESULTS OF
OPERATIONS AND FINANCIAL CONDITION COULD BE MATERIALLY AND ADVERSELY AFFECTED,
THE VALUE OF OUR STOCK COULD DECLINE, AND YOU MAY LOSE ALL OR PART OF YOUR
INVESTMENT.

                  WE FACE RISKS ASSOCIATED WITH OUR OPERATIONS

WE CANNOT PREDICT OUR SUCCESS BECAUSE OUR BUSINESS MODEL IS UNPROVEN AND WE HAVE
OPERATED OUR BUSINESS FOR ONLY A SHORT PERIOD OF TIME.

    Our business model is unproven and a number of other businesses offering
free Internet access have failed. Furthermore, since we only began offering
Internet access in October 1998, we have a limited operating history, which will
make it difficult for you to evaluate our performance. You should carefully
consider the risks and difficulties we may encounter in the new and rapidly
evolving Internet market. These risks include our ability to:

       - retain and increase our user base;

       - generate sufficient revenues to cover our costs;

       - manage our telecommunications costs;

       - develop brand recognition with users and advertisers;

       - provide adequate levels of user support;

       - upgrade and scale our communications network and internal server
         capacity;

       - respond to technological developments in the industry; and

       - comply with evolving standards relating to the use of information
         obtained from, and privacy of, Internet users.

    If we are not able to successfully address these risks, our business,
results of operations and financial condition could be materially and adversely
affected. Please see "Management's Discussion and Analysis of Financial
Condition and Results of Operations" for detailed information on our limited
operating history.

OUR BUSINESS WILL BE SERIOUSLY HARMED IF WE FAIL TO RETAIN AND GROW OUR USER
BASE OR DEMONSTRATE THAT OUR REGISTERED USERS ARE ACTUALLY USING OUR SERVICE.

    The success of our business will depend on our ability to retain our
existing user base, add new users and demonstrate to advertisers that our users
are using our service on a regular basis. To date, we have relied extensively on
"viral" or "word-of-mouth" marketing to attract the vast majority of our users
and will continue to do so for the foreseeable future. Such marketing is outside
of our control and there can be no assurance that it will generate rates of
growth in our user base comparable to what we have experienced to date. In
addition, we intend to generate new users through other distribution channels.
If such distribution channels prove more costly than anticipated, it could
adversely impact our ability to grow. If we are unable to grow our user base,
our ability to generate revenues, decrease per-user telecommunications costs and
implement our strategy will be materially and adversely affected.

                                       5
<PAGE>
    There are a variety of reasons why users would discontinue using our
service. Many users may dislike The ZeroPort--which is always present--or may
not wish to have their online activities tracked and prefer to pay for Internet
access without advertising or tracking. In addition, releases of our software
have had, and may have in the future, reliability and other issues which may
result in user dissatisfaction. To date, we have provided minimal user support
compared to the support offered by other Internet service providers. While we
intend to focus our resources and efforts on enhancing our users' online
experience, there can be no assurance that existing users will accept The
ZeroPort or be satisfied with our user support efforts, or that our service will
match or exceed the quality, speed and reliability of competitive Internet
access services. If our users believe that the level of support they receive is
inadequate, our user turnover rate will likely increase.

    A number of our registered users may not actively use our service for
periods of time. While approximately 1.17 million users had registered for our
service as of June 30, 1999, approximately 613,000 had used our service in the
previous 30 days. If we are not able to demonstrate to our advertisers that we
have an active and growing user base, advertisers may choose not to advertise
with us and our business, results of operations and financial condition could be
materially and adversely affected.

    We also believe that intense competition from our Internet access
competitors, some of which offer many free hours of service, rebates on computer
purchases, or other promotions for new users, will cause some of our existing or
potential users to switch to our competitors' services. It is relatively easy
for Internet users to switch to competing providers and we cannot be certain
that any steps we take will maintain or improve user retention. We also believe
that a number of our users also have Internet access accounts with our
competitors and that such users do not use NetZero as their primary Internet
service provider. In addition, some new users use the Internet only as a novelty
and do not become consistent users of Internet services and, therefore, may be
more likely to discontinue their service. These factors adversely affect our
user turnover rates. We cannot assure you that our user turnover rate will not
increase in the future. Any increase in user turnover rates could have a
material adverse effect on our business, results of operations and financial
condition.

OUR FAILURE TO GENERATE ADVERTISING REVENUES IN QUANTITIES AND AT RATES THAT ARE
SATISFACTORY TO US COULD HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS, RESULTS
OF OPERATIONS AND FINANCIAL CONDITION.

    We do not charge our users any fees for our Internet access and e-mail
services. The success of our business depends primarily on our ability to
generate advertising revenues. We cannot be sure that advertisers will continue
to purchase advertising space on the Internet or that our particular business
model will be attractive to advertisers. A significant portion of our revenues
may be dependent on our ability to fulfill various performance criteria, such as
having our users subscribe to specific services or purchase specific products of
advertisers. Whether such criteria are fulfilled will depend on our ability to
effectively target users through identifying relevant demographic criteria and
developing targeting data. We are in the early stages of that process and may
encounter technical limitations on our ability to target users based on their
demographic information. The quality of our demographic information also depends
on the accuracy of the information provided by our users, which we do not
corroborate. Therefore, we cannot assure you that we will be able to effectively
target users and achieve performance-based revenues. If we fail to do so, our
business, results of operations and financial condition could be materially and
adversely affected.

    In addition, competition for Internet-based advertising revenues is intense
and the amount of available standard banner advertising space on the Internet is
increasing at a significant rate. These

                                       6
<PAGE>
factors are causing Internet advertising rates to decline and we expect that
these rates may continue to decline in the future. Therefore, we cannot assure
you that we will be able to attract advertising revenues in quantities and at
rates that are sufficient to support our business model. Our failure to do so
would likely have a material adverse effect on our business, results of
operations and financial condition.

WE RELY ON A SMALL NUMBER OF TELECOMMUNICATIONS CARRIERS AND MAY BE UNABLE TO
FIND ADEQUATE REPLACEMENTS IF THEIR RATES INCREASE, SERVICE QUALITY DECLINES, OR
IF THEY DISCONTINUE DOING BUSINESS WITH US.

    Our business substantially depends on the capacity, affordability,
reliability and security of our telecommunications networks. To use our
services, users must initiate telephone connections between their personal
computers and computer hardware in local or regional facilities known as points
of presence (POPs) provided by third-party telecommunications carriers. These
telecommunications providers also provide connections between their POPs and our
central computers. Only a small number of telecommunications companies can
provide the network services we require. There has been significant
consolidation in the telecommunications industry, and there is a significant
risk that further consolidation could make us reliant on an even smaller number
of providers. Most of our telecommunications services are provided pursuant to
short-term agreements that the telecommunications service providers can
terminate or elect not to renew. As a result, there is a significant risk that
any or all of our current telecommunications service providers could decide not
to provide us with service at rates acceptable to us, or at all.

    RISK OF CONFLICTS OF INTEREST.  Many telecommunications companies offer, or
have announced that they will begin to offer, Internet access services, making
them direct competitors of ours. In addition, each of our telecommunications
providers supplies network access to some of our competitors, and could choose
to grant those competitors preferential network access, potentially limiting our
users' ability to access the Internet. If our telecommunications service
providers were to decrease the levels of service or access provided to us, or if
they were to terminate their relationships with us for competitive or other
reasons, and we were not able to develop alternate sources of supply, our
business, results of operations and financial condition would be materially and
adversely affected.

    RISK OF UNACCEPTABLE SERVICE QUALITY.  Our reliance on third-party
telecommunications service providers also exposes us to the risks that such
providers will fail to provide service or that their service quality will not be
acceptable. In either event, we would likely lose users who are dissatisfied
with our service, which could materially and adversely affect our business,
results of operations and financial condition. Since we do not have direct
control over our telecommunications carriers' network reliability and the
quality of their service, we cannot assure you that we will be able to provide
consistently reliable Internet access for our users.

    RISK OF PRICE SENSITIVITY.  Our financial results are highly sensitive to
variations in prices for the telecommunications services we purchase. We cannot
assure you that telecommunications prices will decline, or that such prices will
not increase. Some of our telecommunications providers impose minimum connection
charges. Our business could be harmed if minimum connection charges increase or
become more prevalent. In addition, the availability and pricing of POPs varies
geographically, and we may not be able to obtain new or substitute POPs in
certain geographic areas within the required lead times or on commercially
reasonable terms, if at all. We cannot assure you that our telecommunications
providers will continue to provide us access to their POPs on commercially
acceptable price terms, or that alternative services will be available on such
terms.

                                       7
<PAGE>
WE DEPEND ON NETGRAVITY SOFTWARE TO EFFECTIVELY SERVE ADVERTISEMENTS TO THE
ZEROPORT.

    All of our advertisements are served using software licensed from
NetGravity. While there is other software available, it would substantially
disrupt our business in the near term to switch to another provider. As such, we
are reliant on NetGravity and its software. Our agreement with NetGravity
expires in 2001. If NetGravity's software fails to perform as expected, or if we
are not able to renew such agreement or license or internally develop similar
software in the future, we may not be able to effectively display advertisements
to our users. In such event, our business, results of operations and financial
condition would be materially and adversely affected. On July 13, 1999,
DoubleClick, an Internet advertising provider, and NetGravity announced that
they had entered into a merger agreement pursuant to which DoubleClick will
acquire NetGravity in a stock-for-stock transaction.

WE ANTICIPATE FUTURE LOSSES AND NEGATIVE CASH FLOW.

    As of March 31, 1999, we had an accumulated deficit of approximately $7.1
million. We expect that our losses and negative cash flow will increase for the
foreseeable future as we continue to expand our operations and incur expenses in
connection with:

       - purchasing telecommunications service capabilities in anticipation of a
         growing user base;

       - obtaining additional equipment and software for our network
         infrastructure to enable us to expand and improve the quality of our
         services;

       - adding personnel;

       - continuing to develop our direct and indirect sales and marketing
         efforts;

       - increasing our product development efforts; and

       - expanding our user support services.

    Our ability to achieve profitability and positive cash flow depends upon a
number of factors, including our ability to increase revenue or reduce per-user
costs. Although our revenues have grown in recent quarters, we cannot be certain
that we will be able to sustain these growth rates or that we will obtain
sufficient revenues to achieve profitability or positive cash flow. If we do
achieve profitability, we cannot be certain that we can sustain or increase
profitability on a quarterly or annual basis in the future. If we fail to do so,
the market price for our common stock could suffer.

OUR MARKETS ARE VERY COMPETITIVE AND WE MAY NOT BE ABLE TO COMPETE EFFECTIVELY,
ESPECIALLY AGAINST ESTABLISHED INDUSTRY COMPETITORS.

    We compete for users and advertising customers.

    COMPETITION FOR USERS

    We currently compete or expect to compete for users with the following types
of companies that provide access services:

       - established online service and content providers, such as America
         Online and The Microsoft Network;

       - independent national Internet service providers, such as EarthLink,
         MindSpring and Prodigy;

       - national long-distance carriers, such as AT&T, GTE and MCI WorldCom;

                                       8
<PAGE>
       - local telephone companies and regional Bell operating companies, such
         as Pacific Bell;

       - numerous regional and local commercial Internet service providers;

       - computer hardware and software and other technology companies, such as
         IBM and Microsoft;

       - cable operators and online cable services, such as Excite@Home;

       - other free Internet service providers; and

       - nonprofit or educational Internet service providers.

    We face competition for users and expect that competition in this market
will continue to intensify for the foreseeable future. Existing competitors may
take steps such as reducing their subscriber fees, offering promotions for
access services or bundling free access services with other product offerings.
In addition, we believe that new competitors for Internet users, including major
computer manufacturers such as Dell, software companies such as Microsoft, media
and telecommunications companies, will continue to enter the Internet access
market. New entrants or existing competitors could adopt Internet access models
similar to ours, thereby limiting the value of our consumer proposition. As
awareness of the Internet grows, existing competitors are likely to further
increase their emphasis on their Internet access services, resulting in even
greater competition for us. In addition, telecommunications companies with far
greater resources, distribution channels and brand awareness may offer their own
Internet access services to users. These companies have their own
telecommunications network infrastructure and therefore have lower
communications costs in connection with the Internet access services they
provide. These advantages reduce the overall cost of Internet access for such
companies and may significantly increase competitive pressures on us. The
ability of our competitors to acquire other Internet service providers, to enter
into strategic alliances or joint ventures or to bundle other services and
products with Internet access services could also put us at a significant
competitive disadvantage.

    We cannot predict whether we will be able to compete successfully against
current or future competitors. As a result, we cannot assure you that
competitive pressures faced by us will not materially and adversely affect our
business, results of operations or financial condition. Increased competition
could cause us to increase our sales and marketing expenses and related user-
acquisition costs and could also result in increased user turnover and decreased
advertising revenues. Since we do not charge our users membership fees, we may
not be able to offset the effects of these increased costs and we may not have
the resources to continue to compete successfully. These developments would
materially and adversely affect our business, results of operations and
financial condition.

    We also face competition from companies that provide broadband connections
to users' homes, including local and long-distance telephone companies, cable
television companies, electric utility companies, wireless communications
companies and other Internet service providers. These companies may use
broadband technologies to include Internet access or business services such as
Web hosting in their basic bundle of services or may offer Internet access or
business services for little or no additional charge. Most of our service is
offered via dial-up modems which are limited to access speeds of up to 56 kbps.
Broadband technologies enable users to transmit and receive print, video, voice
and data in digital form at significantly faster access speeds. While the market
for such broadband technologies is still emerging, we believe it will continue
to grow and pose an increasingly significant source of competition. We may have
to develop new technologies or add broadband access services to remain
competitive. Our pursuit of these technological advances may require substantial
time and expense. We cannot be certain that we will succeed in adapting our
Internet access service business to compete effectively with these technologies.

                                       9
<PAGE>
    Furthermore, to the extent that we need to provide broadband access
services, we face the risk that the companies that own broadband networks may
prevent us from delivering Internet access through the wire and cable
connections that they own. The availability and terms of Internet service
providers' access to broadband local telephone company networks are under
regulatory and judicial review. Our ability to compete with telephone and cable
television companies that are able to support broadband transmission, and to
provide better Internet services and products, may depend on future regulation
to guarantee open access to the broadband networks. However, in January 1999,
the Federal Communications Commission declined to take any action to mandate or
otherwise regulate access by Internet service providers to broadband cable
facilities at this time. It is unclear whether and to what extent local and
state regulatory agencies will take any initiatives to implement this type of
regulation, and whether they will be successful in establishing their authority
to do so. Similarly, the FCC is considering proposals that could limit the right
of Internet service providers to connect with their users over broadband local
telephone lines. In addition to competing directly in the Internet access
market, both cable and telephone facilities operators are also aligning
themselves with certain Internet service providers who would receive
preferential or exclusive use of broadband local connections to end users. If
high-speed, broadband facilities increasingly become the preferred mode by which
users access the Internet and we are unable to gain access to these facilities
on reasonable terms, our business, results of operations and financial condition
could be materially and adversely affected. In addition, we do not currently
compete internationally. If the ability to provide Internet access
internationally becomes a competitive advantage in the Internet access industry,
we may be at a competitive disadvantage relative to our competitors who offer
such services.

    We cannot predict what effect technological developments will have on our
competitive position. The rapid development of new competing technologies and
standards increases the risk that current or new competitors could develop
products and services that reduce the competitiveness of our products and
services. If our products and services become obsolete or less competitive with
other available products and services, our business, results of operations and
financial condition could be materially and adversely affected.

    COMPETITION FOR ADVERTISING CUSTOMERS

    We compete for Internet advertising and sponsorship revenues with Web search
engine and portal companies such as Yahoo!, Lycos, Excite@Home and Infoseek,
with large Web publishers such as CNN.com and CNET and with other online content
providers such as America Online and Microsoft. Further, we compete with
Internet advertising providers, such as DoubleClick, Adsmart, 24/7 Media and
ValueClick. We also encounter competition from a number of other sources,
including content aggregation companies, advertising sales networks, advertising
agencies, and other companies which facilitate Internet advertising.

    We may not be able to compete successfully against current or future
competitors for advertising revenues, many of whom have longer operating
histories, greater name recognition, larger user bases, significantly greater
financial, technical and marketing resources and more established relationships
with advertisers than we do. These advantages may allow such competitors to
respond more quickly than we can to new or emerging technologies and changes in
advertiser requirements. They may also be able to devote greater resources than
we can to the development, promotion and sale of their products and services.
Such competitors may also engage in more extensive research and development,
undertake more far-reaching marketing campaigns, adopt more aggressive pricing
policies and make more attractive offers to existing and potential employees,
strategic partners, advertisers and Web publishers. In addition, current and
potential competitors have established or may establish cooperative
relationships among themselves or with third parties to increase the ability of
their products or services to address the

                                       10
<PAGE>
needs of our prospective customers. As a result, it is possible that new
competitors may emerge and rapidly acquire significant market share. Increased
competition is likely to result in price reductions, reduced gross margins and
loss of market share. It is possible that we will not be able to compete
successfully or that competitive pressures will materially and adversely affect
our business, results of operations or financial condition.

    Companies doing business on the Internet, including us, must also compete
with television, radio, cable and print media for a share of advertisers' total
advertising budgets. Advertisers may be reluctant to devote a significant
portion of their advertising budget to Internet advertising if they perceive the
Internet to be a limited or ineffective advertising medium.

OUR BUSINESS WILL BE ADVERSELY AFFECTED IF USER DEMAND FOR OUR SERVICE EXCEEDS
OUR TELECOMMUNICATIONS AND SERVER CAPACITY.

    We may from time to time experience dramatic increases in our user base
resulting in sign-ups and usage which exceed our telecommunications capacity and
the capacity of our internal servers. As a result, users may be unable to
register or log on to our service, may experience a general slow-down in their
Internet access or may be disconnected from their sessions. Excessive user
demand could also result in system failures of our internal server networks.
Inaccessability, interruptions or other limitations on the ability to access our
service due to excessive user demand or any failure of our servers to handle
user traffic, would have a material adverse effect on our business, results of
operations and financial condition.

WE MUST ENHANCE OUR INTERNAL NETWORK INFRASTRUCTURE TO MEET ADDITIONAL DEMAND OR
CHANGING USER REQUIREMENTS.

    Our internal network infrastructure is composed of a complex system of
application, database, ad and e-mail servers. Service interruptions originating
within our internal network have occurred in the past and may occur in the
future, especially when usage exceeds capacity. We will need substantial
financial, operational, and management resources to enhance our systems,
particularly our database servers and storage capabilities, to handle a large
number of users. We cannot be certain that we will be able to accomplish this on
a timely basis and at a commercially reasonable cost, or at all. If we fail to
do so, our business, results of operations and financial condition could be
materially and adversely affected.

WE MAY NOT BE SUCCESSFUL IN MANAGING OUR GROWTH.

    Our rapid growth has placed, and is expected to continue to place, a
significant strain on our managerial, operational and financial resources. For
us to effectively manage our rapidly growing operations, we must continue to
assimilate our new personnel and implement and improve our
operational, financial, and management information systems. We will also have to
anticipate our future telecommunications capacity needs within lead-time
requirements. If we fail to procure sufficient quantities of telecommunications
products and services, we may be unable to provide our current and future users
with acceptable service levels. We also run the risk of purchasing excessive
amounts of telecommunications products and services based on incorrect
assumptions and projections regarding increased usage. In such event, we would
be required to bear the costs of excess telecommunications capacity without
commensurate increases in revenues. We cannot assure you that we will be able to
effectively manage these and other aspects of our business. Our failure to do so
would likely have a material adverse effect on our business, results of
operations and financial condition.

                                       11
<PAGE>
IF WE ARE UNSUCCESSFUL IN ESTABLISHING AND MAINTAINING THE NETZERO BRAND, OR IF
WE INCUR EXCESSIVE EXPENSES IN PROMOTING AND MAINTAINING OUR BRAND, OUR
BUSINESS, RESULTS OF OPERATIONS AND FINANCIAL CONDITION WOULD BE MATERIALLY AND
ADVERSELY AFFECTED.

    We believe that establishing and maintaining the NetZero brand is critical
to retain and expand our user base. Promotion of the NetZero brand will depend
on our success in providing high-quality Internet products and services.
However, such success will depend, in part, on the services, products and
efforts of third parties, over which we have little or no control. For instance,
if our third party telecommunication service providers fail to provide quality
service, our users' ability to access the Internet may be interrupted, which may
adversely affect the NetZero brand. If our users and advertisers do not perceive
our existing products and services as high quality, or if we introduce new
products or services or enter into new business ventures that are not favorably
received by our users and advertisers, then we will be unsuccessful in building
brand recognition and brand loyalty in the marketplace. We may also need to
devote substantial resources to create and maintain a distinct brand loyalty
among our users and to promote and maintain the NetZero brand in a very
competitive market. If we are unsuccessful in establishing or maintaining the
NetZero brand or if we incur excessive expenses in promoting and maintaining our
brand, our business, results of operation and financial condition could be
materially and adversely affected.

OUR SUCCESS DEPENDS UPON THE SUCCESSFUL DEVELOPMENT OF NEW PRODUCTS AND SERVICES
IN THE FACE OF RAPIDLY EVOLVING TECHNOLOGY.

    The market for Internet access is characterized by rapidly changing
technology, evolving industry standards, changes in user needs, and frequent new
service and product introductions. Our future success will depend, in part, on
our ability to use leading technologies effectively, to continue to develop our
technical expertise, and to enhance our existing services and develop or obtain
new services to meet changing user needs on a timely and cost-effective basis.
We may not be successful in achieving these goals.

    RELIANCE ON THIRD PARTIES.  We rely upon third parties to help us develop
technologies that enhance our current product and service offerings. If our
relationships with such third parties are impaired or terminated, then we would
have to find other developers on a timely basis or develop technology completely
on our own. We cannot predict whether we will be able to obtain the third-party
technology necessary for continued development and introduction of new and
enhanced products and services. In addition, we cannot predict whether we will
be able to obtain third-party technology on commercially reasonable terms or
replace third-party technology in the event such technology becomes unavailable,
obsolete or incompatible with future versions of our products or services. The
absence of, or any significant delay in, the replacement of third-party
technology could have a material adverse effect on our business, results of
operations and financial condition.

    RISK RELATED TO CHANGING STANDARDS.  We believe that our ability to compete
successfully will also depend upon the continued compatibility and
interoperability of our services with products and architectures offered by
various vendors. Although we intend to support emerging standards in the market
for Internet access, industry standards may not be established or, if they are
established, we may not be able to conform to these new standards in a timely
fashion and maintain a competitive position in the market. For instance, we have
been notified that Sun Microsystems is upgrading its JAVA language and that the
new version will require more memory to implement. Our software uses the JAVA
language extensively and we will have to modify our resources accordingly to
accommodate the new version. We cannot assure you that we will be able to make
such modifications, or any other modifications which may be required to adapt to
new or changing standards, in a cost-effective and timely manner, or at all. In
addition, others may develop services or technologies that will render our
services or technology noncompetitive or obsolete. Our business and prospects
could be seriously harmed if we are not able to adapt to changes in

                                       12
<PAGE>
technology and industry standards, and to develop and introduce new and enhanced
products and service offerings.

    RISK OF NEW TECHNOLOGY.  We can provide no assurances that future advances
in technology will be beneficial to, or compatible with, our business.
Furthermore, we may not successfully use new technologies effectively or adapt
our proprietary technology to user requirements or emerging industry standards
on a timely basis. Our ability to remain technologically competitive may require
substantial expenditures and lead time. If we are unable to adapt in a timely
manner to changing market conditions or user requirements, our business, results
of operations and financial condition could be materially and adversely
affected.

WE MAY NOT BE SUCCESSFUL IN PROTECTING OUR PROPRIETARY RIGHTS OR AVOIDING CLAIMS
THAT WE INFRINGE UPON THE PROPRIETARY RIGHTS OF OTHERS.

    Our success depends in part upon our software and related documentation. We
principally rely upon copyright, trade secret, and contract laws to protect our
proprietary technology. We cannot be certain that we have taken adequate steps
to prevent misappropriation of our technology or that our competitors will not
independently develop technologies that are substantially equivalent or superior
to our technology. Our ability to prevent others from using our software could
materially and adversely affect our business, results of operation and financial
condition.

    In addition, since we provide our Internet access software for free, we are
extremely susceptible to various forms of unauthorized use of our software. For
instance, we have experienced, and expect to continue to experience, numerous
instances of third parties selling unauthorized copies of our software. Others
have attempted to charge fees for installing our software without our
permission. Such actions could adversely affect NetZero's brand name.

    We have permission and, in some cases, licenses from each developer of the
software that we bundle in NetZero's front-end software product for users.
Although we do not believe that the software or the trademarks we use or any of
the other elements of our business infringe on the proprietary rights of any
third parties, third parties may assert claims against us for infringement of
their proprietary rights and these claims may be successful. In addition, a
number of third-party owners of patents have claimed to hold patents that cover
various forms of online transactions or online technology. As with other online
service providers, patent claims could be asserted against us based upon our
services or technologies.

    We could incur substantial costs and diversion of management resources in
the defense of any claims relating to proprietary rights, which could materially
and adversely affect our business, results of operations and financial
condition. Parties making these claims could secure a judgment awarding
substantial damages as well as injunctive or other equitable relief that could
effectively block our ability to license our products in the United States or
abroad. Such a judgment against us could prevent us from operating our business
or have other material adverse effects on our business, results of operations
and financial condition. If a third party asserts a claim relating to
proprietary technology or information against us, we may seek licenses to the
intellectual property from the third party. We cannot be certain, however, that
third parties will extend licenses to us on commercially reasonable terms, or at
all. If we fail to obtain the necessary licenses or other rights, it could
materially and adversely affect our business, results of operations and
financial condition.

WE MAY BE UNABLE TO OBTAIN THE ADDITIONAL CAPITAL REQUIRED TO GROW OUR BUSINESS.

    Our ability to grow depends significantly on our ability to expand our
operations by contracting for additional POPs and expanding our internal network
infrastructure. These expansion efforts will require significant advance capital
equipment expenditures and commitments for telecommunications capacity. If the
proceeds from this offering, cash on hand, cash generated from

                                       13
<PAGE>
operations and the amounts available under lease lines, are not sufficient to
meet our cash requirements, we will need to seek additional capital from public
or private equity or debt sources to fund our growth and operating plans and
respond to other contingencies. We may not be able to raise needed cash on terms
acceptable to us or at all. Financings may be on terms that are dilutive or
potentially dilutive to our stockholders. If sources of financing are required,
but are insufficient or unavailable, we will be required to modify our growth
and operating plans to the extent of available funding, which would have a
material adverse effect on our business, results of operations and financial
condition.

OUR NETWORK AND BUSINESS IS VULNERABLE TO SECURITY BREACHES, VIRUSES AND
INAPPROPRIATE USE BY INTERNET USERS, WHICH COULD DISRUPT OUR SERVICE.

    The future success of our business will depend on the security of our
network and, in part, on the security of the network infrastructures of our
third-party telecommunications service providers, over which we have no control.
Computer viruses or problems caused by our users or other third parties, such as
the sending of excessive volumes of unsolicited bulk e-mail or "spam", could
lead to interruptions, delays, or cessation in service to our users. In
addition, the sending of "spam" through our network could result in third
parties asserting claims against us. We cannot assure you that we would prevail
in such claims and our failure to do so could result in large judgments which
would have a material and adverse effect on our business, results of operation
and financial condition. Users or other third parties could also potentially
jeopardize the security of confidential information stored in our computer
systems or our users' computer systems by their inappropriate use of the
Internet, including "hacking" or "cracking", which could cause losses to us or
our users or deter persons from using our services. Users or third parties may
also potentially expose us to liability by "identity theft", or posing as
another NetZero user. Unauthorized access by current and former employees or
others could also potentially jeopardize the security of confidential
information stored in our computer systems and those of our users.

    We expect that our users will increasingly use the Internet for commercial
transactions in the future. Any network malfunction or security breach could
cause these transactions to be delayed, not completed at all, or completed with
compromised security. Users or others may assert claims of liability against us
as a result of any failure by us to prevent these network malfunctions and
security breaches, and may deter others from using our services, which could
cause our business prospects to suffer. Although we intend to continue using
industry-standard security measures, such measures have been circumvented in the
past, and we cannot assure you that these measures will not be circumvented in
the future. We also cannot assure you that the security measures of our
third-party network providers will be adequate. In addition, to alleviate
problems caused by computer viruses or other inappropriate uses or security
breaches, we may have to interrupt, delay, or cease service to our users, which
could have a material adverse effect on our business, results of operations and
financial condition.

    In addition, various software programs have been developed that specifically
target The ZeroPort to disable our ability to deliver advertisements to a user.
While we believe we have been able to limit the effectiveness of such attempts,
we cannot assure you that we will be able to continue to do so in the future.
Widespread adoption of this type of software would materially and adversely
affect our ability to operate our business.

WE WILL DEPEND ON A SMALL NUMBER OF KEY CUSTOMERS FOR A SIGNIFICANT PORTION OF
OUR REVENUES.

    We anticipate that a small number of customers may account for a significant
portion of our revenues. For example, we anticipate deriving a substantial
portion of our revenues from an agreement with LookSmart for the quarter ended
June 30, 1999, and expect that this agreement will continue to account for a
substantial percentage of our revenues through April 2000 when the

                                       14
<PAGE>
agreement expires. Additionally, two other customers accounted for 20% and 24%
of our revenues for the nine-month period ended March 31, 1999. Our business,
results of operations and financial condition will be materially and adversely
affected if we are unable either to renew our material agreements or to replace
such agreements with similar agreements with new customers.

WE ARE DEPENDENT ON THIRD-PARTY HARDWARE SUPPLIERS.

    The expansion of our network infrastructure and the expansion of Internet
services in general is placing, and will continue to place, a significant demand
on our suppliers, some of which have limited resources and production capacity.
From time to time, we have experienced delayed delivery from suppliers of
modems, servers, and other equipment. In particular, our servers are a critical
part of our infrastructure and we will need to add additional servers to expand
our operations. We currently purchase, and expect to continue to purchase, all
of our servers from Sun Microsystems. Since we do not have an agreement with Sun
Microsystems regarding future server purchases, we have no assurance that Sun
Microsystems will continue to supply servers to us. We may be unable to
implement our planned expansion and our users may be unable to connect to our
network if:

       - we are not able to obtain additional modems, servers and other
         equipment in a timely manner;

       - such equipment is not available on commercially acceptable terms; or

       - we are unable to develop alternative sources of supply, if required.

WE HAVE LIMITED EXPERIENCE WITH THE THIRD-PARTY SOFTWARE WE USE TO RUN OUR
OPERATIONS.

    Virtually every aspect of our operations, including finance, billing,
accounting, storage and retrieval of user data, and advertisement tracking, uses
or interfaces with a centralized software system provided by Oracle. We have
only limited experience with the operation of this system. Difficulty with the
operation of, or errors, defects or malfunctions in the operation of this
system, could result in loss of data, erroneous overcharges or undercharges to
advertising customers or disruption of operations, any one of which could
materially and adversely affect our business, results of operations and
financial condition.

FAILURE TO ACHIEVE YEAR 2000 COMPLIANCE MAY HAVE MATERIAL ADVERSE EFFECTS ON OUR
BUSINESS.

    A significant portion of the world's computer hardware and software has
historically used only two digits to identify the year in a date, often meaning
that the computer will fail to distinguish dates in the 21st century from dates
in the 20th century. As a result, various problems may arise from the improper
processing of dates and date-sensitive calculations by computers and other
machinery as the Year 2000 is approached and reached. These problems include
system failures or miscalculations causing disruptions of operations, including,
among other things, a temporary inability to process transactions, send invoices
or engage in similar business activities.

    Our failure, or the failure of third parties on which we rely, to adequately
address Year 2000 readiness issues could result in an interruption, or a
failure, of our normal business activities or operations. Presently, we believe
that the primary risks that we face with regard to the Year 2000 are those
arising from third-party services or products. In particular, we depend heavily
on third party vendors to provide both network services and equipment. A
significant Year 2000-related disruption of these network services or equipment
could cause our users and advertisers to consider seeking alternate providers or
advertising space, or cause an unmanageable burden on user service and technical
support. This, in turn, could materially and adversely affect our business,
results of operations and financial condition.

                                       15
<PAGE>
    In addition, the failure of our internal computer systems or of third-party
equipment or software to operate without Year 2000 complications could require
us to incur significant unanticipated expenses to remedy any problems and could
expose us to claims for losses incurred by our users due to such Year 2000
complications. The defense of any such claims, with or without merit, could
require us to incur substantial costs and would divert management's time and
attention, which could have a material adverse effect on our business, results
of operations and financial condition.

    Furthermore, our business depends on the continued operation of, and
widespread access to, the Internet. To the extent that the normal operation of
the Internet is disrupted by the Year 2000 issue, or if a large portion of our
users and advertisers are unable to access the Internet due to Year 2000-related
issues in connection with their own systems, our business, results of operations
and financial condition could be materially and adversely affected.

WE RELY ON A RELATIVELY NEW MANAGEMENT TEAM AND NEED ADDITIONAL PERSONNEL TO
GROW OUR BUSINESS.

    Most of our senior management team has only recently joined us. For example,
Mark Goldston, our Chief Executive Officer, joined us in March 1999, Charles
Hilliard, our Chief Financial Officer, joined us in April 1999, and Perri
Procida, our Senior Vice President, Sales, joined us in May 1999. There can be
no assurance that we will successfully assimilate our recently hired officers or
that we can successfully locate, hire, assimilate and retain qualified key
management personnel. Our business is largely dependent on the personal efforts
and abilities of our senior management and certain other key personnel. Any of
our officers or employees can terminate his or her employment relationship at
any time. The loss of these certain key employees or our inability to attract or
retain other qualified employees could seriously harm our business and
prospects. We do not carry key man life insurance on any of our key employees.

    Our future success also depends on our ability to attract, retain and
motivate highly skilled technical, managerial, editorial, merchandising,
marketing and user service personnel. We plan to dramatically hire additional
personnel in all areas of our business. Competition for such personnel is
intense, particularly in the Internet and high technology industry. As a result,
we may be unable to successfully attract, assimilate or retain qualified
personnel. We may also be unable to retain the employees we currently employ or
attract additional technical personnel. The failure to retain and attract the
necessary personnel could have a material adverse effect on our business,
results of operations and financial condition.

OUR OPERATIONS AND SERVICES ARE VULNERABLE TO NATURAL DISASTERS.

    Our operations and services depend on the extent to which our computer
equipment and the telecommunications infrastructure of our third-party network
providers is protected against damage from fire, earthquakes, power loss,
telecommunications failures, and similar events. A significant portion of our
computer equipment, including critical equipment dedicated to our Internet
access services, is located at our headquarters and at a co-location facility in
Los Angeles, California. Despite precautions taken by us and our third-party
network providers, over which we have no control, a natural disaster or other
unanticipated problems at our headquarters, network hub, or a third-party
network provider POP could cause interruptions in the services that we provide.
If disruptions occur, we may have no means of replacing these network elements
on a timely basis or at all. We do not currently maintain fully redundant or
back-up Internet services, backbone facilities or other fully redundant
computing and telecommunications facilities. Extensive or multiple interruptions
in providing users with Internet access are a primary reason for user decisions
to stop using access services. Accordingly, any disruption of our services due
to system failure could have a material and adverse effect on our business,
results of operations and financial condition. Furthermore, we do not currently
have any business disruption insurance.

                                       16
<PAGE>
IF WE ARE UNABLE TO SUCCESSFULLY INTEGRATE FUTURE ACQUISITIONS INTO OUR
OPERATIONS, THEN OUR RESULTS AND FINANCIAL CONDITION MAY BE ADVERSELY AFFECTED.

    We evaluate acquisition opportunities on an ongoing basis and at any given
time may be engaged in discussions with respect to possible acquisitions or
other business combinations. We may seek strategic acquisitions that can
complement our current or planned business activities. Such acquisitions may not
be available at the times or on terms acceptable to us, or at all. In addition,
acquiring a business involves many risks, including:

       - potential disruption of our ongoing business and diversion of resources
         and management time;

       - unforeseen obligations or liabilities;

       - possible inability of management to maintain uniform standards,
         controls, procedures and policies;

       - difficulty assimilating the acquired operations and personnel;

       - risks of entering markets in which we have little or no direct prior
         experience;

       - potential impairment of relationships with employees or users as a
         result of changes in management; and

       - potential dilutive issuances of equity, large and immediate write-offs,
         the incurrence of debt, and amortization of goodwill or other
         intangible assets, any of which could materially or adversely affect
         our results of operations and financial condition.

    We cannot assure you that we will make any acquisitions or that we will be
able to obtain additional financing for such acquisitions, if necessary. If any
acquisitions are made, we cannot assure that we will be able to successfully
integrate the acquired business into our operations or that the acquired
business will perform as expected.

OUR QUARTERLY OPERATING RESULTS MAY FLUCTUATE IN FUTURE PERIODS AND WE MAY FAIL
TO MEET EXPECTATIONS.

    Our revenues and operating results may vary significantly from quarter to
quarter due to a number of factors, including those set forth in this "Risk
Factors" section. In future quarters, our operating results may be below the
expectations of public market analysts and investors and the price of our common
stock may fall. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations".

                 WE FACE RISKS RELATED TO THE INTERNET INDUSTRY

WE FACE RISKS RELATING TO UNCERTAIN LEGAL LIABILITY AND GOVERNMENT REGULATION
ASSOCIATED WITH THE INTERNET.

    The law relating to the liability of Internet service providers for
information carried on, stored on, or disseminated through their networks is
continuing to evolve and remains unsettled. While no one has ever filed a claim
against us relating to information carried on, stored on, or disseminated
through our network, someone may file a claim of that type in the future. If
that happens, we may have to spend significant amounts of money to defend
ourselves against these claims and, if we are not successful in our defense, the
amount of damages that we may have to pay could be significant. Our liability
insurance may not cover potential claims relating to the Internet services we
provide or may not be adequate to indemnify us for all liabilities that may be
imposed on us. Any costs that we incur as a result of defending these claims or
the amount of liability that we may

                                       17
<PAGE>
suffer if our defense is not successful could materially and adversely affect
our business, results of operations and financial condition.

    Additionally, a number of legislative and regulatory proposals under
consideration by federal, state, local and foreign governmental organizations
may lead to laws or regulations concerning online content, user privacy,
taxation, parental consent for access by their minor children, access charges,
liability for third-party activities, bulk e-mail or "spam", encryption
standards, e-commerce, domain name registration and use, copyright infringement,
and other intellectual property issues. It is also uncertain as to how existing
laws will be applied by the judiciary to the Internet. The adoption of new laws
or the application of existing laws may decrease the growth in the use of the
Internet, which could in turn decrease the demand for our services, increase our
cost of doing business or otherwise have a material adverse effect on our
business, results of operations and financial condition.

    We cannot predict the impact, if any, that any future regulatory changes or
developments may have on our business, results of operations and financial
condition. Changes in the regulatory environment relating to the Internet access
industry, including regulatory changes that directly or indirectly affect
telecommunication costs or increase the likelihood or scope of competition from
regional telephone companies or others, could have a material adverse effect on
our business, results of operations and financial condition.

    REGULATION OF CONTENT AND ACCESS--LAWS PROTECTING MINORS.  Prohibition and
restriction of Internet content and access could dampen the growth of Internet
use, decrease the acceptance of the Internet as a communications and commercial
medium, expose us to liability and thereby have a material adverse effect on our
business, results of operations and financial condition. A variety of
restrictions on content and access, primarily as they relate to children, have
been enacted or proposed. The Child Online Protection Act of 1998 prohibits and
imposes criminal penalties and civil liability on anyone engaged in the business
of selling or transferring, by means of the World Wide Web, material that is
harmful to minors without restricting access to such material by persons under
seventeen years of age. In addition, the Federal Telecommunications Act of 1996
imposes fines on any entity that knowingly permits any telecommunications
facility under such entity's control to be used to make obscene or indecent
material available to minors via an interactive computer service. Numerous
states have adopted or are currently considering similar types of legislation.
We cannot predict whether any claim under such federal statutes, similar state
statutes or common law will be asserted against us, or if asserted, whether it
will be successful. In addition, laws have been proposed which would require
Internet service providers to supply, at cost, filtering technologies to limit
or block the access of minors to unsuitable materials on the Internet. The
imposition of content restrictions and potential liability for materials carried
on or disseminated through our systems could require us to implement measures to
reduce our exposure to such liability. Such measures may require the expenditure
of substantial resources or the discontinuation of certain product or service
offerings. Further, the costs of defending against any such claims and potential
adverse outcomes of such claims could have a material adverse effect on our
business, results of operations and financial condition.

    LIABILITY FOR DEFAMATION, NEGLIGENCE AND INFRINGEMENT.  Because users
download and redistribute materials that are cached or replicated by us in
connection with our Internet services, claims could be made against us under
both U.S. and foreign law for defamation, negligence, copyright or trademark
infringement, or other theories based on the nature and content of such
materials. While we have attempted to obtain safe harbor protection against
claims of copyright infringement under the Digital Millenium Copyright Act of
1998, there can be no guarantee that we will prevail in any such claims. We also
could be exposed to liability with respect to the offering of third-party
content that may be accessible through our services, including links to
Web-sites maintained by our users or other third parties, or posted directly to
our Web-site, and subsequently

                                       18
<PAGE>
retrieved by a third party through our services. It is also possible that if any
third-party content provided through our services contains errors, third parties
who access such material could make claims against us for losses incurred in
reliance on such information. You should know that these types of claims have
been successfully brought against online service providers. In particular,
copyright and trademark laws are evolving both domestically and internationally,
and it is uncertain how broadly the rights provided under these laws will be
applied to online environments. It is impossible for us to determine who the
potential rights holders may be with respect to all materials available through
our services.

    PRIVACY CONCERNS.  We provide users with free Internet access and other free
services in exchange for demographic information when they register with us. In
addition, we can track and use information relating to our users' online
behavior when they are connected to the Internet through our service. Internet
user privacy has become an issue both in the United States and abroad and some
commentators, privacy advocates and government bodies have recommended or taken
actions to limit the use of personal profiles or other personal information by
those collecting such information, particularly as it relates to children. For
example, the Children's Online Protection Act authorizes the Federal Trade
Commission to develop regulations for the collection of data from children by
commercial Web-site operators. However, we cannot predict the exact form of the
regulations that the FTC may adopt. There can be no assurance that the United
States or foreign nations will not adopt additional legislation to protect such
privacy. Any such action could affect the way in which we are allowed to conduct
our business, especially those aspects that involve the collection or use of
personal information, and could have a material adverse effect on our business,
results of operations and financial condition.

    TAX TREATMENT OF INTERNET AND E-COMMERCE.  The tax treatment of the Internet
and e-commerce is currently unsettled. A number of proposals have been made at
the federal, state and local levels and by certain foreign governments that
could impose taxes on the online sale of goods and services and certain other
Internet activities. Recently, the Internet Tax Information Act was signed into
law, placing a three-year moratorium on new state and local taxes on Internet
commerce. However, there can be no assurance that future laws imposing taxes or
other regulations on commerce over the Internet would not substantially impair
the growth of e-commerce and as a result have a material adverse effect on our
business, results of operations and financial condition.

    TELECOMMUNICATIONS REGULATION.  As an Internet service provider, we are not
currently directly regulated by the Federal Communications Commission or any
other agency, other than regulations applicable to businesses generally. In a
report to Congress adopted on April 10, 1998, the FCC reaffirmed that Internet
service providers should be classified as unregulated "information service
providers", rather than regulated "telecommunications providers" under the terms
of the Telecommunications Act of 1996. This finding is important because it
means that regulations that apply to telephone companies and similar carriers do
not apply to us. We also are not required to contribute a percentage of our
gross revenues to support "universal service" subsidies for local telephone
services and other public policy objectives, such as enhanced communications
systems for schools, libraries, and some health care providers. The FCC action
is also likely to discourage states from regulating Internet service providers
as telecommunications carriers or imposing similar subsidy obligations.

    Nevertheless, Internet-related regulatory policies are continuing to
develop, and it is possible that we could be exposed to regulation in the
future. For example, in the same report to Congress, the FCC stated its
intention to consider whether to regulate voice and fax telephony services
provided over the Internet as "telecommunications" even though Internet access
itself would not be

                                       19
<PAGE>
regulated. We cannot predict whether the FCC will modify its current policies
against regulation of Internet service providers.

    We could also be affected by any change in the ability of our users to reach
our network through a dial-up telephone call without any additional charges. The
FCC has ruled that connections linking end users to their Internet service
providers are jurisdictionally interstate rather than local, but the FCC did not
subject such calling to the access charges that apply to traditional
telecommunications companies. Local telephone companies assess access charges to
long distance companies for the use of the local telephone network to originate
and terminate long distance calls, generally on a per-minute basis. We could be
adversely affected by any regulatory change that would result in application of
access charges to Internet service providers because this would substantially
increase the cost of using the Internet. Since the largest component of our
operating costs is comprised of telecommunications costs, any increase in such
costs would have a material adverse effect on our business, results of
operations and financial condition.

    State public utility commissions generally have declined to regulate
enhanced or information services. Some states, however, have continued to
regulate particular aspects of enhanced services in limited circumstances, such
as where they are provided by incumbent local exchange carriers that operate
telecommunications networks. Moreover, the public service commissions of some
states continue to review potential regulation of such services. We cannot
assure you that state regulatory authorities will not seek to regulate aspects
of these activities as telecommunications services.

    WORKFORCE INVESTMENT ACT OF 1998.  Section 508 of the Workforce Investment
Act of 1998 requires that all Web-sites operated by a federal agency, as well as
those operated by anyone doing business with the federal government, modify
their Web-sites to make them accessible to those who are handicapped. There are
proposals to extend this Act to all Web-sites, which could increase our costs
and make our service less attractive to the non-handicapped.

SEASONAL TRENDS IN INTERNET USAGE AND ADVERTISING SALES MAY NEGATIVELY AFFECT
OUR BUSINESS.

    Seasonal trends could affect the advertising revenues we generate from
operating our Internet services. To the extent that our advertising revenues
depend on the amount of usage by our users, any seasonal fluctuations in
Internet usage could affect our advertising revenues during such periods of
fluctuation. In addition, the rate at which new users sign up for our services
may be lower during certain seasons and holiday periods. Because our operating
history is so limited, it is difficult for us to accurately predict these trends
and plan accordingly. Since our operating expenses are based on our expectations
of future revenues, it is possible that seasonal fluctuations could materially
and adversely affect our business, results of operations and financial
condition.

IF INTERNET USAGE DOES NOT CONTINUE TO GROW, WE MAY NOT BE ABLE TO EXECUTE OUR
BUSINESS PLAN.

    If the use of the Internet does not continue to grow or evolves in a way
that we cannot address, our business, financial condition and operating results
could be materially and adversely affected. Substantially all of our revenues
are dependent on the continued use and expansion of the Internet. Use of the
Internet has grown dramatically, but no assurance can be given of the continued
use and expansion of the Internet. A decrease in the demand for Internet
services or a reduction in the currently anticipated growth for such services
could have a material adverse effect on our business, results of operations and
financial condition. We have based our business model on certain assumptions
regarding the continued growth of use of the Internet. If these assumptions turn
out to be incorrect, our projections may be materially different than actual
results or circumstances, which could have a material adverse effect on our
business, results of operations and financial condition.

                                       20
<PAGE>
PROTECTION OF OUR DOMAIN NAMES IS UNCERTAIN.

    We currently hold the Web domain name relating to our brand, NetZero.com, as
well as numerous other related Web domain names. The acquisition and maintenance
of domain names generally is regulated by governmental agencies and their
designees. The regulation of domain names in the United States and in foreign
countries is subject to change in the near future. Such changes in the United
States are expected to include a transition from the current system to a system
which is controlled by a non-profit corporation and the creation of additional
top-level domains. Governing bodies may establish additional top-level domains,
appoint additional domain name registrars, or modify the requirement for holding
domain names. As a result, we may be unable to acquire or maintain relevant
domain names in the countries in which we conduct, or plan to conduct, business.
Furthermore, the relationship between regulations governing domain names and
laws protecting trademarks and similar proprietary rights is unclear. Therefore,
we may be unable to prevent third parties from acquiring domain names that are
similar to, infringe upon, dilute or otherwise decrease the value of our
trademarks and other proprietary rights.

                WE ARE SUBJECT TO RISKS RELATED TO THE OFFERING

NO PUBLIC MARKET EXISTS FOR OUR COMMON STOCK.

    Prior to this offering, there has been no public market for our common stock
and we cannot be sure that an active trading market for our common stock will
develop or continue as a result of this offering. We will determine the initial
public offering price of the shares of our common stock through negotiations
with the underwriters. Please see "Underwriting" for more information.

THE CONCENTRATED CONTROL OF OUR COMPANY COULD ADVERSELY AFFECT STOCKHOLDERS.

    After this offering, our executive officers, directors and 5% stockholders,
in the aggregate, will control   % of our voting stock. As a result, these
stockholders will have significant influence and ability to control most matters
requiring board and stockholder approval, including a significant corporate
transaction like the sale of our company, a change in control or the terms of
future equity financings. Such stockholders may have interests adverse to those
of other stockholders in general, and they may use their influence to approve or
take actions which are adverse to your interests.

PURCHASERS IN THIS OFFERING WILL EXPERIENCE IMMEDIATE AND SUBSTANTIAL DILUTION.

    If you purchase common stock in this offering, you will incur immediate and
substantial dilution in the net tangible book value of the shares purchased. We
estimate this dilution to be approximately $           per share, or
approximately   % (based on an assumed initial public offering price of
$           ). Additional dilution may occur upon the exercise of outstanding
stock options.

OUR STOCK PRICE COULD FLUCTUATE SIGNIFICANTLY.

    The trading price of our common stock is likely to be volatile and could
fluctuate widely in response to factors such as the following, some of which are
beyond our control:

       -  general economic factors;

       -  changes in expectations of our future financial performance, including
           financial estimates by securities analysts and investors;

       -  changes in operating and stock price performance of other Internet and
           online companies similar to us; or

       -  future sales of our common stock.

                                       21
<PAGE>
    Domestic and international stock markets often experience significant price
and volume fluctuations. These fluctuations, as well as general economic and
political conditions unrelated to our performance, may adversely affect the
price of our common stock. In particular, following initial public offerings,
the market prices for stocks of Internet and technology-related companies often
reach levels that bear no relationship to the operating performance of these
companies. These market prices are generally not sustainable and could vary
widely. If our common stock trades to such high levels following this offering,
it could eventually experience a significant decline. Therefore, you may not be
able to resell shares of our stock at or for more than the price you paid.

SHARES ELIGIBLE FOR PUBLIC SALE AFTER THIS OFFERING COULD ADVERSELY AFFECT OUR
STOCK PRICE.

    The market price of our common stock could decline as a result of sales by
our existing stockholders of shares of common stock in the market after this
offering, or the perception that these sales could occur. These sales also might
make it difficult for us to sell securities in the future at a time and at a
price that we deem appropriate. You should read "Shares Eligible For Future
Sale" for a more detailed discussion of when and how many additional shares of
our stock may be sold after this offering.

OUR MANAGEMENT HAS BROAD DISCRETION OVER THE USE OF THE PROCEEDS FROM THIS
OFFERING.

    The net proceeds of this offering are estimated to be approximately
$      million (approximately $               million if the underwriters'
over-allotment option is exercised in full) at an assumed initial public
offering price of $           per share and after deducting the estimated
underwriting discount and estimated offering expenses. Our management will
retain broad discretion as to the allocation of the proceeds of this offering
and may use such proceeds in a manner in which you may not agree.

CERTAIN PROVISIONS IN OUR CHARTER DOCUMENTS COULD DETER TAKEOVER EFFORTS.

    Provisions of our Amended and Restated Certificate of Incorporation, Bylaws
and Delaware law could make it more difficult for a third party to acquire us,
even if doing so would be beneficial to our stockholders. In addition, we are
subject to the provisions of Section 203 of the Delaware General Corporation
Law, as amended from time to time. This statute could prohibit or delay the
accomplishment of mergers or other takeover or change in control in attempts
with respect to us and, accordingly, may discourage attempts to acquire us.

                                USE OF PROCEEDS

    Our net proceeds from the sale of the   shares of common stock offered
hereby are estimated to be approximately $      ($      million if the
underwriters exercise their over-allotment option in full) based upon an assumed
offering price of $      per share and after deducting estimated underwriting
discounts and commissions and estimated offering expenses payable by us.

    We intend to use the net proceeds of the offering:

       - for use in expansion of our business, including additions and
         enhancements to our server and network infrastructure and the
         functionality of The ZeroPort;

       - as additional working capital; and

       - for general corporate purposes.

    As of the date of this prospectus, we cannot specify with certainty the
particular uses for the net proceeds to be received upon completion of the
offering. Pending such uses, the net proceeds of the offering will generally be
invested in short-term, interest-bearing investment-grade instruments. We intend
to maintain flexibility in our use of the proceeds of this offering. The amounts
actually expended for each of the purposes listed above are at our discretion
and may vary significantly depending upon a number of factors, including the
growth of our user base, capital spending requirements and developments in the
Internet access market. Accordingly, we reserve the right to reallocate the
proceeds of this offering as we deem appropriate.

    From time to time, in the ordinary course of business, we evaluate possible
acquisitions of, or investments in, businesses, products and technologies that
are complementary to our business. A portion of the net proceeds may be used to
fund acquisitions or investments. We currently have no arrangements, agreements
or understandings, and are not engaged in active negotiations with respect to
such acquisitions or investments.

                                DIVIDEND POLICY

    We have never declared nor paid cash dividends on our capital stock. We
currently intend to retain all available funds for use in the operation and
expansion of our business and do not anticipate paying any cash dividends in the
foreseeable future. Any future determination to pay dividends will be at the
discretion of our Board of Directors and will depend on our results of
operations, financial conditions, contractual and legal restrictions and other
factors it deems relevant. We expect that any lease financing or credit
agreements we enter into will prohibit the payment of dividends without the
lender's consent.

                                    DILUTION

    Our pro forma net tangible book value as of March 31, 1999 was approximately
$40.1 million, or $0.45 per share. Pro forma net tangible book value per share
represents the amount of total tangible assets less total liabilities divided by
the number of shares of common stock outstanding as of March 31, 1999 after
giving pro forma effect to the automatic conversion of all outstanding shares of
preferred stock and our May 1999 convertible preferred stock offering. After
giving effect to our sale of       shares of common stock offered by this
prospectus at an assumed initial public offering price of $               per
share and after deducting estimated underwriting discounts and commissions and
estimated offering expenses, the pro forma net tangible book value of as of
March 31, 1999 would have been $      million, or $      per share. This
represents an immediate increase in pro forma net tangible book value of
$               per share to existing stockholders and an immediate dilution in
pro forma net tangible book value of $               per share to investors
purchasing common stock in this offering.

    The following table illustrates this per share dilution:

</TABLE>

    The foregoing table gives pro forma effect to the automatic conversion of
all outstanding shares of preferred stock and our May 1999 convertible preferred
stock offering, each as if they had occurred at March 31, 1999, and assumes no
exercise of the underwriters' over-allotment option or shares underlying
outstanding options. As of March 31, 1999, options to purchase 3,455,000 shares
of common stock were outstanding at a weighted average exercise price of $0.06
per share. To the extent that these options are exercised, new investors will
experience further dilution. See "Description of Capital Stock" and note 6 of
the notes to our financial statements.

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

    THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. ACTUAL EVENTS OR RESULTS MAY DIFFER MATERIALLY FROM THOSE
INDICATED IN SUCH FORWARD-LOOKING STATEMENTS. SEE "INFORMATION REGARDING
FORWARD-LOOKING STATEMENTS". THE FOLLOWING DISCUSSION OF OUR FINANCIAL CONDITION
AND RESULTS OF OPERATIONS ALSO SHOULD BE READ IN CONJUNCTION WITH THE FINANCIAL
STATEMENTS AND NOTES TO THOSE STATEMENTS INCLUDED ELSEWHERE IN THIS PROSPECTUS.

OVERVIEW

    NetZero is pioneering a new Internet service model that provides consumers
with free and unlimited Internet access while offering online advertisers a
highly effective way to reach those users through precise targeting technology.

    We were incorporated in July 1997 and launched our service in October 1998.
For the period from inception until October 1998, we had no revenues and our
operating activities related primarily to the development of our proprietary
zCast software. Since launching our service, we have continued these operating
activities and have also focused on developing changes to The ZeroPort to
enhance its features and functionality; implementing the zCast Server network
cell infrastructure; hiring personnel; contracting with third-party
communications providers; selling advertising; marketing our service to
potential sponsors of placements on The ZeroPort and pursuing distribution
arrangements such as those with Compaq and Xerox. We have spent, and will
continue to spend, significant resources on these activities.

    REVENUES.  We intend to generate revenues through banner advertisements,
referrals of our users to other Web-sites, sponsorships on The ZeroPort,
performance-based agreements and distribution arrangements. Historically, The
ZeroPort has been limited in its capabilities and our revenue has been generated
primarily from non-targeted banner advertising. We anticipate that a significant
portion of our banner inventory will be sold in a similar manner in the future.
We have recently begun generating revenues from selling targeted banner
advertisements and by automatically referring our users to specified Web-sites
when they log on. We expect to release a substantially upgraded version of The
ZeroPort in the near future that will expand The ZeroPort features and offer a
number of additional ways to generate revenues, including selling exclusive and
non-exclusive sponsorships of various buttons and a marquee space on The
ZeroPort as well as sponsorships of a customizable ticker tape and browse window
on The ZeroPort. Our advertising revenues could be derived from a variety of fee
arrangements, including fixed fees or fees based on the number of users referred
to the advertiser's Web-site, the number of ads delivered, other performance
criteria, or any combination of the foregoing.

    We anticipate that we will receive higher advertising rates for targeted
advertisements and sponsorships than for non-targeted banner advertisements.
However, we have limited experience in selling and managing these types of
arrangements and there can be no assurance that we will successfully sell all of
the various advertising services we intend to offer or that such arrangements
will generate significant revenues or higher advertising rates. Our success with
performance-based fee arrangements may depend on our ability to effectively
target users. We are in the early stages of that process and may encounter
technical and other limitations on our ability to successfully target users
based on their demographic information, including limitations associated with
privacy concerns. We cannot assure you that we will be able to achieve
anticipated revenues. In addition, while we believe that the growth of our user
base will enhance the value of our services to our advertising customers, there
can be no assurance that we will adequately perform under these arrangements or
that we will be able to replace such arrangements on comparable terms, if at
all. The failure to generate significant sponsorships on The ZeroPort or the
failure to replace significant contracts when they expire could adversely affect
our revenues and results of operations.

                                       28
<PAGE>
    Banner advertising, sponsorship and performance-based revenues are
recognized ratably in the periods in which the advertisement or sponsorship
placement is displayed or in which the performance criteria are achieved,
provided that no significant NetZero obligations remain and collection of the
resulting receivable is probable. To the extent banner delivery commitments or
performance criteria are not met, NetZero either loses the right to such
revenues or defers the corresponding revenues until the remaining ads are
delivered or performance criteria are achieved.

    Our advertising revenues are subject to the effects of seasonality.
Advertisers typically purchase impressions on a forward basis. If purchasing
patterns or timing of purchasing by advertisers were to change, our operations
could be materially affected.

    Our revenues will be significantly affected by our ability to grow our user
base. If we are unable to grow our user base and maintain a favorable
demographic profile of users, we may be unable to attract significant
commitments from advertisers or satisfy our agreements with our advertisers
relating to performance criteria.

    The Company does not currently anticipate that inflation will have a
material impact on its results of operations.

    COST OF REVENUES.  Cost of revenues consists of telecommunications costs,
allocated depreciation of our network equipment, allocated occupancy costs and
personnel and related expenses of our network. We intend to expend significant
amounts of capital and to make significant commitments to future
telecommunications capabilities with the expectation of a rapidly increasing
subscriber base and anticipated usage patterns. Our failure to accurately
forecast our users' needs could result in significant overcapacity which would
adversely impact our result of operations. Conversely, underforecasting usage
could adversely impact the ability of our users to receive adequate service and
adversely impact our reputation and our ability to maintain or increase our
subscriber base. We have a limited history in forecasting our users'
requirements and there can be no assurance that we will be able to accurately
forecast such requirements in the future.

    SALES AND MARKETING.  Sales and marketing expenses include salaries, sales
commissions, benefits, travel and related expenses for our direct sales force,
fees paid to third-party advertising sales agents, marketing, and sales support
functions. In an effort to increase our revenues, user base and brand awareness,
we expect to increase significantly the amount of spending on sales and
marketing over the next year. Marketing costs associated with increasing our
user base, which to date have been minimal, are expensed in the period incurred.

    PRODUCT DEVELOPMENT.  Product development costs include expenses for the
development of new or improved technologies designed to enhance the performance
of our service, including the salaries and related expenses for our software
engineering department, as well as costs for contracted services, content,
facilities and equipment. We believe that a significant level of product
development activity is necessary for our business and intend to increase
significantly the amount of spending to fund this activity.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses include
salaries, benefits and expenses for our executive, finance, legal and human
resources personnel. In addition, general and administrative expenses include
fees for professional services, occupancy costs. We expect general and
administrative expenses to increase in absolute dollars as we continue to expand
our administrative infrastructure to support the anticipated growth of our
business, including costs associated with being a public company.

    STOCK-BASED CHARGES.  In connection with the grant of stock options to
employees and the imposition of restrictions on shares of stock held by certain
founders during the nine months ended March 31, 1999, we recorded aggregate
deferred compensation of approximately $5.0 million. This

                                       29
<PAGE>
deferred compensation represented the difference between the deemed fair value
of our common stock for accounting purposes and the exercise price of these
options or shares at the date of grant. Deferred compensation is presented as a
reduction of stockholders' equity and amortized over the vesting period of
applicable options, generally four years.

</TABLE>

    REVENUES.  Revenues for the quarter ended March 31, 1999 were $781,000,
which represented an increase of $659,000, or 540%, from $122,000 for the
quarter ended December 31, 1998. The increase was primarily attributable to
increased sales of banner advertisements.

    COST OF REVENUES.  Cost of revenues for the quarter ended March 31, 1999 was
$4.0 million, which represented an increase of $2.9 million, or 274%, from $1.1
million for the quarter ended December 31, 1998. The increase was primarily
attributable to increased telecommunications expense related to the growth in
our user base.

    SALES AND MARKETING.  Sales and marketing expenses for the quarter ended
March 31, 1999 were $290,000, which represented an increase of $152,000, or
110%, from $138,000 for the quarter ended December 31, 1998. The increase was
due to the hiring of four new salespeople into our direct sales force.

    PRODUCT DEVELOPMENT.  Product development expenses for the quarter ended
March 31, 1999 were $292,000, which represented an increase of $82,000, or 39%,
from $210,000 for the quarter ended December 31, 1998. The increase was due to
the hiring of seven new software engineers.

                                       30
<PAGE>
    GENERAL AND ADMINISTRATIVE.  General and administrative expenses for the
quarter ended March 31, 1999 were $1.1 million, which represented an increase of
$685,000, or 160%, from $429,000 for the quarter ended December 31, 1998. The
increase was due to the hiring of several key employees, including Mark
Goldston, our Chief Executive Officer.

    STOCK-BASED CHARGES.  In the nine months ended March 31, 1999, we recorded
total deferred compensation of $5.0 million in connection with stock option
grants and restricted founders' shares. We are amortizing this amount over the
vesting periods of the applicable options or shares, resulting in expense of
$277,000 for the nine months ended March 31, 1999. Stock-based charges in the
nine months ended March 31, 1999 also include a charge for $67,000 related to
the issuance of options on the Series A and B redeemable convertible preferred
stock.

    DEPRECIATION AND AMORTIZATION.  Depreciation and amortization for the
quarter ended March 31, 1999 was $43,000, which represented an increase of
$19,000 or 79%, from $24,000 for the quarter ended December 31, 1998. The
increase was due primarily to the purchase of fixed assets to be used in the
business.

    INTEREST AND OTHER INCOME (EXPENSE), NET.  Interest income consists of
earnings on our cash and cash equivalents. Interest expense consists primarily
of interest expense on capital equipment leases. Interest income, net, for the
quarter ended March 31, 1999 was $30,000, which represented an increase of
$36,000 from net interest expense of $6,000 in the quarter ended December 31,
1998. The increase was primarily attributable to the signing of our Series C
equity investment agreement, which provided our company with $11.4 million in
cash.

    INCOME TAXES.  As a result of operating losses and our inability to
recognize a benefit from our deferred tax assets, we have not recorded a
provision for income tax for the nine months ended March 31, 1999. We have
provided a full valuation allowance on our deferred tax assets, consisting
primarily of net operating loss carry-forwards, because of uncertainty regarding
their realizability.

    Our operating results may fluctuate substantially in the future as a result
of a variety of factors, many of which are outside of our control, including
those discussed elsewhere in this prospectus. We plan to significantly increase
our operating expenses and capital expenditures to expand our sales and
marketing efforts, promote the NetZero brand, continue to enhance the features
and functionality of The ZeroPort, upgrade our internal network infrastructure,
pursue new distribution channels and hire new personnel across all levels of our
organization. We determine our operating expenses largely on the basis of
anticipated growth in our revenues and certain of our expenses are fixed in the
short term. There are risks associated with the timing and achievement of
revenue targets due to a variety of factors, and there can be no assurance that
revenues will increase commensurately with expenses. As a result of these and
other factors, our operating results may vary substantially from quarter to
quarter. See "Risk Factors" for a discussion of some of the factors which could
lead to substantial operating losses.

    In addition, seasonal trends could affect the revenues we generate. To the
extent that our revenues depend on the amount of usage by our users, any
seasonal fluctuations in Internet usage could affect our revenues during such
periods of fluctuation. Moreover, the rate at which new users sign up for our
services may be lower during certain seasons and holiday periods. Because our
operating history is so limited, it is difficult for us to accurately predict
these trends and plan accordingly. Since our operating expenses are based on our
expectations of future revenues, it is possible that seasonal fluctuations could
materially and adversely affect our business, results of operations and
financial condition.

    Due to the foregoing factors, we believe that quarter-to-quarter comparisons
of operating results are not necessarily a good indication of future
performance.

LIQUIDITY AND CAPITAL RESOURCES

    Since our inception, we have financed our operations primarily through the
private placement of equity securities, raising $13.7 million through March 1999
and an additional $33.3 million in May of 1999. At May 31, 1999 we had $36.6
million in cash and cash equivalents.

    Net cash used for our operating activities was $5.9 million for the nine
months ended March 31, 1999. Net cash used for operating activities consisted
primarily of net operating losses and increases in accounts receivable and
restricted cash balances, which were partially offset by increases in accounts
payable.

    Net cash used for our investing activities was $951,000 for the nine months
ended March 31, 1999. Net cash used for investing activities consisted primarily
of capital expenditures for computer equipment, purchased software and office
equipment. As our operations expand, we anticipate that our planned purchases of
capital equipment will require significant additional expenditures over the next
12 months.

    Net cash provided by our financing activities was $13.6 million for the nine
months ended March 31, 1999. Net cash provided by financing activities was
principally attributable to the private sale of convertible preferred stock.

    As of March 31, 1999, our principal commitments consisted of office and
equipment leases. Future minimum cash payments under these non-cancelable
commitments are $13.7 million through the year 2009.

    As of March 31, 1999, we had $6.7 million in cash and cash equivalents. We
currently anticipate that our existing cash and cash equivalents, the net
proceeds from our May 1999 Series D preferred stock financing and this offering,
proceeds from equipment leases and any cash generated from operations will be
sufficient to fund our operating activities, capital expenditures and other
obligations through at least the next 12 months. However, we may need to raise
additional funds in order to fund more rapid expansion, to expand our marketing
activities, to develop new or enhance existing services or products, to respond
to competitive pressures or to acquire complementary services, businesses or
technologies. If we are not successful in generating sufficient cash flow from
operations, we may need to raise additional capital through public or private
financings, strategic relationships or other arrangements. This additional
funding, if needed, might not be available on terms acceptable to us, or at all.
Our failure to raise sufficient capital when needed could have a material
adverse effect on our business, results of operations and financial condition.
If additional funds were raised through the issuance of equity securities, the
percentage of stock owned by our then-current stockholders would be reduced.
Furthermore, such equity securities might have rights, preferences or privileges
senior to those of our common stock.

YEAR 2000

    Many existing computer systems and software are coded to accept only two
digit entries in the date code field and cannot distinguish 21st century dates
from 20th century dates. If not corrected, there could be system failures or
miscalculations causing disruptions of operations, including, among other
things, an inability to process transactions or engage in normal business
activities. As a result, many companies' software and computer systems may need
to be upgraded or replaced to comply with these "Year 2000" requirements.

    OUR STATE OF READINESS

    We have not assessed the impact that the Year 2000 problem may have on our
operations. We plan to implement the following process to assess and remedy any
Year 2000 problems with our operations:

                                       32
<PAGE>
    Phase I: Assessment Operations (estimated completion in August 1999);

    Phase II: Prepare Formal Test Plan (estimated completion in September 1999);

    Phase III: Implement Test (estimated completion in October 1999); and

    Phase IV: Remediation of Year 2000 issues (estimated completion in November
1999).

    While we have not formally assessed the impact that the Year 2000 problem
may have on our operations, we believe the following four distinct areas of our
operations may be affected by the Year 2000 problem:

    INTERNALLY DEVELOPED SOFTWARE.  We have internally developed a substantial
portion of the systems and software that we use to operate and monitor our
online operations. While we have not assessed the Year 2000 readiness of our
internally-developed systems and software, we believe that they are Year 2000
compliant because we attempted to construct them to avoid the Year 2000 problem.

    THIRD-PARTY HARDWARE AND SOFTWARE SUPPLIERS.  We use third-party equipment
and software that may or may not be Year 2000 compliant. As a result, our
ability to address Year 2000 issues is to a large extent dependent upon the Year
2000 readiness of these third parties' hardware and software products. These
products include servers manufactured by Sun Microsystems, Network equipment
manufactured by Cisco, database management, financial application and other
software licensed from Oracle, our advertisement server software from
NetGravity, and JAVA, a programming language licensed from Sun Microsystems that
we use to implement most of our internally developed software. We are contacting
the third parties from whom we have purchased any hardware and software products
to validate that such products are Year 2000 compliant. We intend to complete
our assessment of these parties' products by the end of August 1999. However,
since we purchased the most current product versions available from these third
parties, we believe these applications are Year 2000 compliant.

    TELECOMMUNICATIONS CARRIERS.  We are entirely dependent on our
telecommunications carriers to provide access between their POPs and our
network. We are initiating discussions with all of our telecommunications
carriers to determine the extent to which we are vulnerable to those third
parties' Year 2000 issues. We intend to obtain Year 2000 readiness disclosure
statements from each of these partners by the end of August 1999 to confirm that
their systems are Year 2000 compliant. In addition, we believe that several of
our telecommunications carriers have conducted Year 2000 compliance checks as a
part of their standard disaster recovery simulations. We expect to resolve any
significant Year 2000 issues with our telecommunications carriers; however, in
the event they do not achieve Year 2000 compliance, we may have to seek
alternative suppliers of telecommunications services.

    NON-IT SYSTEMS.  Our non-information technology systems, such as heating and
air conditioning, security systems and other embedded technology may be subject
to Year 2000 risks. If our air conditioning unit were to fail, our servers and
other electrical equipment could overheat and be seriously damaged or lost. If
our security systems were to fail, we would be exposed to a significant risk of
property loss and damage and personal injury.

    THE COSTS OF ADDRESSING OUR YEAR 2000 ISSUES

    To date, we have not incurred any material expense in connection with
identifying, evaluating and remediating Year 2000 compliance issues. We believe
that substantially all of the expense that we will incur in the future relating
to the Year 2000 problem will be costs associated with time spent by our
employees in the evaluation process and Year 2000 compliance in general. We do
not expect the total costs of our Year 2000 compliance efforts to be material.
However, if these costs

                                       33
<PAGE>
are substantially higher than we anticipate, they could have a material adverse
effect on our business.

    THE RISKS ASSOCIATED WITH OUR YEAR 2000 ISSUES

    If Year 2000 issues prevent our users from accessing the Internet, our
business and operations will suffer. Any failure of our systems and our
communications infrastructure with respect to the Year 2000 problem could result
in:

       - increased user turnover and corresponding loss of advertising revenues
         resulting from decreased impressions; or

       - increased allocation of our resources to address Year 2000 problems
         without additional revenues commensurate with such dedication of
         resources.

    OUR CONTINGENCY PLANS

    We have not developed a contingency plan with respect to Year 2000 risks.
However, we believe our worst case scenario is the interruption of our business
resulting from Year 2000 failure of our third party systems which provide access
between their POPs and our internal network. We plan on developing a contingency
plan in the future, but have not determined the scope of such plan, or the
timetable by which such a plan would be developed.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

    In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") No. 98-1, "Software for Internal
Use", which provides guidance on accounting for the cost of computer software
developed or obtained for internal use. We expect that the adoption of SOP 98-1
will not have a material impact on our financial position, results of operations
or cash flows. We will be required to implement SOP No. 98-1 in the first
quarter of fiscal 2000.

    In April 1998, the AICPA issued SOP No. 98-5, "Reporting on the Costs of
Start-Up Activities". SOP No. 98-5 requires that all start-up costs related to
new operations must be expensed as incurred. In addition, start-up costs that
were capitalized in the past must be written off when SOP No. 98-5 is adopted.
We expect that the adoption of SOP No. 98-5 will not have a material impact on
our financial position, results of operations or cash flows. We will be required
to implement SOP No. 98-1 in the first quarter of fiscal 2000.

    In June 1998, The Financial Accounting Standards Board issued SFAS No. 133
"Accounting for Derivative Instruments and Hedging Activities". The statement
requires the recognition of all derivatives as either assets or liabilities in
the balance sheet and the measurement of those instruments at fair value. The
accounting for changes in the fair value of a derivative depends on the planned
use of the derivative and the resulting designation. Because we do not currently
hold any derivative instruments or engage in hedging activities, the impact of
the adoption of SFAS No. 133 is not currently expected to have a material impact
on our business, results of operations or financial condition. We will be
required to implement SFAS No. 133 in the first quarter of fiscal 2001.

NETZERO

    NetZero is pioneering a new Internet service model that provides consumers
with free and easy access to the Internet while offering online advertisers a
highly effective way to reach those users through our proprietary targeting
technology. We offer users a simple and compelling proposition--free and
unlimited Internet access, as well as free e-mail and navigational tools to
enhance their online experience. The value of NetZero's proposition is evidenced
by our growth; between our October 1998 launch and June 30, 1999, approximately
1.17 million users registered for our service. During June 1999, approximately
613,000 of these users accessed our service and were delivered over 830 million
advertising impressions. Our services are offered in over 1,100 cities
nationwide.

    When users access the Internet through our service, we display a small
window on their computer screen called The ZeroPort which is always visible
while they are online, regardless of where they navigate. Users can move The
ZeroPort to different locations on their screens but cannot close it or reduce
its size. The ZeroPort displays advertisements, advertiser-sponsored buttons,
icons and drop-down menus. By clicking on The ZeroPort, users can navigate
directly to sites and services such as news, sports, finance and shopping. We
generate revenues by selling advertisements and sponsorships on The ZeroPort. We
plan to expand our revenue sources to include fees from advertisers and
merchants when our users subscribe for services, purchase products or satisfy
other performance criteria.

    Our service is based on two key principles. First, we provide users free
Internet access and other free services. We obtain demographic information when
users register for our services which we supplement with our ability to track
their online activity. Second, we offer advertisers access to a large audience
and enable them to target messages, based on user demographics and online
behavior, for extended periods of time. Our model combines certain of the
characteristics of network television--where a mass audience has free access to
an advertising-supported medium-- with the targeting advantages of direct
marketing. We believe NetZero is positioned to redefine the Internet access
model and the way products and services are marketed online.

INDUSTRY BACKGROUND

    GROWTH OF THE INTERNET

    The emergence and wide acceptance of the Internet has fundamentally changed
how millions of people worldwide share information, communicate and conduct
business. International Data Corporation (IDC) estimates that the number of
Internet users in the United States will increase from approximately 63 million
in 1998 to approximately 177 million by the end of 2003. The growth in Internet
usage is being driven by a number of factors, including:

       - a large and growing installed base of personal computers;

       - easier, faster, and more reliable access to the Internet;

       - improvements in network security, infrastructure and bandwidth;

       - the rapidly expanding availability of online content and commerce
         sites; and

       - an increasing amount of offline advertising promoting the Internet.

    TRADITIONAL INTERNET ACCESS

    There are more than 6,000 ISPs in the United States today, varying widely in
geographic coverage, user focus and the nature and quality of services provided
to users. With the exception of

                                       35
<PAGE>
a few large providers, the vast majority of ISPs do not offer branded nationwide
coverage. A number of ISPs are beginning to supplement their basic access with
services such as e-commerce and telecommunications.

    ISPs generally charge users monthly access fees and fees for additional
services, such as Web hosting. IDC estimates that users spend an average of
approximately $250 per year for Internet access. Telecommunications costs
associated with providing dial-up Internet access have declined in recent years
with the emergence of wholesale providers that resell capacity to ISPs. These
providers have built and continue to build networks on a large scale and are
able to spread the cost of their networks over multiple ISPs. Though access fees
charged to users have declined over time, they have not fallen as quickly as the
costs of personal computers or telecommunications. We believe that while users
are generally focused on speed and reliability as they evaluate Internet access
services, they are also increasingly focusing on cost, particularly as their
other computing costs decline and since the rest of their online experience is
generally free.

    GROWTH OF INTERNET ADVERTISING

    Traditional television, radio and print advertising has focused on building
awareness-- repeating a branded message with high frequency to a large
audience--rather than targeting individual users based on demographics or
behavior. The Internet has emerged as an attractive new medium for advertising
because it offers features that are unavailable in traditional media. For
example, the Internet enables advertisers to target specific types of users,
receive direct feedback on their advertisements, and capture valuable data on
user preferences while reaching a broad, global audience.

    The Internet also represents an attractive medium for direct marketing,
which has traditionally been conducted through direct mail and telemarketing.
The interactive nature of the Internet enables direct marketers to deliver
targeted promotions to users. The success of any direct marketing campaign is
generally measured by the response rate of users. The Internet has the potential
to enable direct marketers to increase user response rates and decrease costs
per transaction by targeting campaigns to particular users based on their
demographic profile, interests and online behavior. Jupiter Communications
estimates that the amount spent on consumer Internet advertising in the United
States will grow from $1.9 billion in 1998 to $7.7 billion in 2002.

    LIMITATIONS OF CURRENT INTERNET ADVERTISING

    While the Internet offers advertisers and direct marketers a number of
advantages over traditional media, there remain significant challenges to
realizing the full potential of online advertising. To date, online advertising
has generally consisted of banner advertisements and sponsorships on heavily
trafficked portals and other Web content sites. We believe that users who visit
those sites tend not to spend a great deal of time on any one page and can
generally scroll traditional banner advertisements off of their screens, leading
advertisers to increasingly question the effectiveness of these advertisements.
In addition, most online advertisers are unable to successfully target their
audiences, largely due to a lack of precise demographic and navigation data on
users. As advertisers and direct marketers continue to increase their online
spending, they are seeking solutions and technologies which will enable them to
deliver highly-targeted messages, receive real-time feedback and capitalize on
other potential advantages of online advertising.

THE NETZERO SOLUTION

    We have created a business model that provides free, unlimited Internet
access to users and a powerful direct marketing tool for advertisers and
sponsors.

                                       36
<PAGE>
    OUR VALUE PROPOSITION TO USERS

    FREE, UNLIMITED INTERNET ACCESS AND E-MAIL.  We offer users free unlimited
access to the Internet and navigational tools to enhance their online
experience. We also provide each of our users with a free e-mail account. Users
can access our services with a computer running Windows 95, Windows 98 or
Windows NT 4.x and with at least 16 MB of RAM, a 14.4 kbps or faster dial-up
modem and any standard Internet browser.

    THE ZEROPORT.  We combine navigational tools with our other service to
enhance our users' online experience. The ZeroPort contains buttons conveniently
displayed in a dashboard-like setting around the advertising window. These
buttons enable users to go directly to specific Web-sites across a variety of
categories. For example, The ZeroPort has a button that allows users to search
the Internet through LookSmart, an Internet services directory that currently
appears as the start page for our service. We plan to add significant
functionality to The ZeroPort, including advertiser-sponsored buttons that can
link directly to various popular Internet services and sites, as well as a
customizable ticker which can display the latest news headlines, sports scores
and stock market quotes, among other new features. Our user data enables us to
deliver information and advertising intended to be tailored to our users'
interests.

    The following schematic illustrates the ZeroPort, including the features and
functions that we expect to add to the next release:

[Graphic depiction of The Zero Port, including an advertising window,
sponsorship buttons and information ticker appears here]

    OUR VALUE PROPOSITION TO ADVERTISERS AND DIRECT MARKETERS

    PROMINENT AND SUSTAINED ADVERTISING MEDIUM.  In contrast to most portal and
content sites which display advertising, NetZero remains with users the entire
time they are online. Once users are logged on through NetZero, The ZeroPort
remains in full view throughout the session, including when they are waiting for
pages to download, navigating the Internet and even engaging in non-browsing
activities such as sending or receiving e-mail. The constant visibility of The
ZeroPort allows advertisements to be displayed for a specified period of time,
typically from 20 to 30 seconds.

    DYNAMIC TARGETING AND INFORMATION GATHERING.  Our users provide demographic
information when they register for our service. Utilizing our proprietary zCast
technology, we can track our users' behavior the entire time they are online
through our service. As a result, we are able to deliver targeted advertisements
and measure their effectiveness. For example, our users can receive ads from a
brokerage firm when they are viewing sites containing stock quotes or financial
news, or receive promotions from a bookseller when browsing sites containing
book reviews. We also offer advertisers the ability to display ads in The
ZeroPort while users are viewing a competitor's Web-site or when viewing the
advertisers' own Web-site, thereby complementing their site and precluding
competitive ads from being displayed at that time.

    PERFORMANCE-BASED ADVERTISING.  While the Internet has emerged as an
important mass advertising medium, advertisers are increasingly seeking
solutions to ensure that they maximize

                                       37
<PAGE>
their return on investment. To meet the demands of advertisers who value
specific results from their online marketing campaigns, we intend to offer
pricing alternatives where we are paid only if our users link to an advertiser's
site and subscribe for services, purchase products or satisfy some other
performance criteria.

THE NETZERO STRATEGY

    Our objective is to redefine the Internet access model and the way products
and services are marketed online. The key elements of our strategy are:

    BUILD A PREMIER BRAND.  We believe that establishing brand awareness is
critical to attracting and retaining users and advertisers and intend to make
brand building prominent in our marketing efforts. Our strategy is to promote
the perception of the NetZero brand among users as a premier provider of
Internet services and among advertisers as the most effective means of targeting
potential customers. To achieve this objective, we plan to advertise the NetZero
brand extensively online, as well as through traditional media, including
television, radio and print advertising. We plan to support the quality brand
image conveyed through our marketing campaign by establishing sponsorship
relationships with leading online and offline consumer brands as advertisers.

    INCREASE USER BASE.  We intend to continue to rapidly increase our user
base. Aggregating a large audience will provide economies of scale, increase our
attractiveness to advertisers and enhance our ability to enter into strategic
marketing arrangements. To date, our user base has grown almost exclusively
through word-of-mouth referrals by existing users. We plan to expand our
audience through more aggressive user-acquisition programs, including
co-branding, distribution of CDs to install our service, bundling and retail
distribution relationships, and television, radio and print advertising.

    IMPROVE USER EXPERIENCE.  We will continue efforts to improve the experience
of users and maximize their retention by enhancing the technical capabilities
and ease of use of our service, making our users' online experience more
relevant and personal, providing additional user support options and adding new
services.

    PURSUE DIVERSE REVENUE SOURCES.  Our service enables us to pursue revenues
from diverse sources, including banner advertising, sponsorships and e-commerce.
To date, advertisers and merchants have paid us for placements of ads and
sponsorships on The ZeroPort and for referrals to their Web-sites. We also plan
to offer advertisers enhanced advertising and tracking tools and to generate
fees through referrals and other arrangements when our users open accounts with,
or purchase products or services from, our advertisers.

    MAXIMIZE SALES AND MARKETING EFFICIENCY.  We intend to continue to pursue a
two-pronged strategy to sell and market advertising and sponsorship on The
ZeroPort. First, our internal sales and marketing organization will focus on
developing innovative sponsor relationships with leading brand marketers in
addition to selling banner advertisements on The ZeroPort. We believe sponsoring
arrangements will tend to have longer terms, elements of exclusivity and higher
rates than typical banner advertising. Second, we will leverage the resources of
outside sales organizations to enhance our ability to sell large quantities of
ad inventory within a short period of time. We have entered into agreements with
Adsmart, 24/7 Media and ValueClick to augment our efforts to sell traditional
banner advertising as we continue to expand our internal sales organization.

    MINIMIZE NETWORK COSTS.  Network costs associated with providing our service
are a major component of our cost structure. Our strategy of purchasing
telecommunications capacity from third-party wholesale providers, rather than
building and managing our own network, has enabled

                                       38
<PAGE>
us to rapidly expand the geographic scope of our service and accommodate user
growth while reducing capital expenditures. Although we may at some point
consider investing in various forms of networking infrastructure, particularly
in cases where a given type of access would otherwise be difficult or
prohibitively costly to obtain, we currently intend to continue using wholesale
providers and to negotiate volume discounts as our purchasing power increases.
We believe this will enable us to reduce costs, continue to rapidly expand our
service coverage and to ensure reliable service through multiple wholesale
providers.

    We also believe that our strategy of using wholesale providers will enable
us to remain network-independent and to switch providers or technologies as cost
or performance improvements become available. As a result, we believe we can be
flexible in responding to user demand for higher-speed access and other types of
improved service such as DSL, cable modems, high-speed wireless access and other
broadband technologies.

SOURCES OF REVENUE

    We generate, or plan to generate, revenues from the following services. An
agreement with a significant customer typically involves a number of the
services offered to maximize the effectiveness of the customer's advertising or
sponsorship campaigns.

    BANNER ADVERTISING. Our advertisers can currently purchase standard banner
advertising on The ZeroPort at rates comparable to those generally available for
banner advertising. Advertisers can also purchase targeted advertising on The
ZeroPort so that their advertisements are displayed only to users satisfying
certain criteria specified by our advertisers, such as gender, interests,
language preferences and geographic location. We also offer advertisers the
opportunity to target specific Web-sites so that their ads are displayed on The
ZeroPort when users are viewing such Web-sites, including those of competitors
of the advertisers. They can also purchase advertising space on TheZeroPort when
users are viewing the advertisers' own Web-sites, thereby complementing the site
and precluding competitors from displaying their advertisements on The ZeroPort
at that time. We charge our advertisers premium rates for targeted advertising
services. Direct advertisers that have placed banner advertisements on The
ZeroPort include Bell South, eBay, Microsoft, Netscape and theglobe.com.

    SPONSORSHIP. The ZeroPort contains a number of buttons and, in the future,
will contain additional buttons, drop-down menus, a marquee space and a
customizable ticker tape and browse window which are or will be available for
sponsorship by advertisers. The buttons and drop-down menus will be organized
into categories such as news, sports, finance and shopping. This allows
advertisers to purchase exclusive or non-exclusive sponsorships for a specific
category, and helps direct interested users to their sites. The ticker tape will
display sports, news and stock market quotes.

    WEB-REFERRALS AND E-COMMERCE. We enter into arrangements with e-commerce
merchants and service providers where we receive fees based on the number of
users who are referred to their Web-site, subscribe for their services, purchase
their products, or satisfy other performance criteria. These arrangements can be
based on our ability to direct users to specific Web-sites, on advertisements
and sponsorships on The ZeroPort, as well as on targeted e-mail messages sent
directly by advertisers to users who elect to receive such messages via their
free e-mail accounts.

    OTHER. We have also received revenues from co-branding and distribution
arrangements and intend to pursue other diverse revenue opportunities.

    Our revenues from any of the above sources could include a variety of fee
arrangements, including fixed fees or fees based on the number of users referred
to the advertiser, the number of ads delivered, other performance criteria, or
any combination of the foregoing.

                                       39

SALES AND MARKETING

    ADVERTISING SALES

    We sell and market advertising and sponsorship on The ZeroPort through our
direct sales force, which comprised 12 people as of June 30, 1999. Our sales
force is structured as a multi-region organization with regional managers, key
account managers and a national planning group. Our sales personnel operate out
of our headquarters in Westlake Village, California and our offices in New York
and San Francisco. We also have agreements with Adsmart, 24/7 Media and
ValueClick to sell traditional banner advertising as we continue to expand our
internal sales organization.

    We recently started selling sponsorships for placements on, and links from,
The ZeroPort. For example, we granted eBay the sponsorship for person-to-person
auctions, linking eBay to the "Auction" button or a drop-down menu on The
ZeroPort. We expect our sponsorship arrangements could involve some level of
exclusivity and will command higher prices than traditional online advertising.
Sponsorship advertising involves a greater degree of integration and
consultation between NetZero and the marketer. We intend to focus our sales and
marketing organization on building and sustaining these relationships, including
working to select the appropriate media strategy based on the sponsor's
requirements for timing, number of impressions and desired response rate.

    USER ACQUISITION

    To date, we have relied extensively on word-of-mouth marketing to attract
the vast majority of our users. We plan to increase our user marketing efforts,
including television, radio and print media advertising, direct marketing
campaigns such as widespread direct mailing and distribution of CDs to install
our software, and bundling, co-branding, and retail distribution arrangements.
For instance, we have entered into the following distribution arrangements to
build our brand, acquire users and generate revenues:

    COMPAQ. In April 1999, we entered into a twelve-month agreement with Compaq
under which Compaq will bundle and distribute our NetZero software with its
Presario products. Compaq will pay for substantially all of the marketing,
distribution and advertising costs of the bundled product in exchange for up to
10% of The ZeroPort's banner advertising inventory on NetZero sessions initiated
from the bundled Presario products. In addition, all users who sign up for
NetZero's service through software installed on the bundled product will be
directed to AltaVista's start page each time they log-on to NetZero's service
for the term of the agreement. With certain exceptions, through February 2000,
Compaq will not offer any other free Internet access services on its Presario
products and we will not bundle our service with the personal computers of any
other manufacturer or enter into any agreements with Compaq's retailers for the
distribution of our services.

    XEROX. In July 1999, we entered into a non-exclusive arrangement with Xerox
under which Xerox agreed to bundle and distribute CDs for installing our
software with its computer peripheral products. Xerox has agreed to pay us a fee
per CD and purchase advertising from us through December 1999.

USER SUPPORT

    Our user service strategy is to build programs designed to increase user
satisfaction and retention, while controlling costs and accommodating our rapid
growth. To date, our user service has been handled in-house, but we plan to
engage in selective outsourcing of certain aspects of our user service to
vendors to provide us with greater efficiency and scalability for future growth.

                                       40
<PAGE>
    We provide online and offline "self-help" services that provide a variety of
support options to our users, including our SPEEDY Assistant offline software
which is loaded onto the user's computer when the service is initially installed
from the CD and can also be downloaded from our Web-site. This offline tool
assists users in loading and operating our software, provides answers to common
questions and helps users set up their e-mail account through step-by-step
instructions. We also provide comprehensive help, tutorials, advisories, answers
to frequently asked questions and tips via our Web-site, fax back support and
e-mail. We intend to provide the same support via real-time chat and message
boards. We also provide telephone support between 8:00 a.m. and 9:00 p.m.
(Pacific time), Monday through Saturday. We have entered into an agreement with
a third party to develop and outsource a "pay for what you need" program which
will provide our users with toll-free telephone access, 24 hours per day, 7 days
per week, to a support representative for a per-incident basis charge.

    Our user service organization continually monitors quantitative metrics such
as average wait time, first call resolution rate and abandon rate. We plan to
implement a problem tracking system that will allow recurring problems to be
identified and communicated to the appropriate user service function for
resolution. We are also in the process of enhancing our in-house support system
through the addition of an e-mail distribution system and a dynamic Web-based
database. The database will be accessible by our outsourcing partners, in-house
user service representatives and our customers on a real-time basis to provide
answers to frequently asked questions and to ensure delivery of user service in
a consistent manner.

TECHNOLOGY

    We have developed and continue to expand a proprietary software system
called zCast that enables us to track our users' navigational activities and to
deliver highly-targeted advertising. zCast has two major components:

    THE ZCAST CLIENT SOFTWARE

    The zCast Client application is the software product that includes The
ZeroPort which is installed on all of our users' personal computers. The
ZeroPort is visible and appears on top of other windows while a connection to
NetZero's service is maintained. The zCast Client performs multiple tasks,
including:

       - establishing a connection to the NetZero service;

       - capturing demographic information;

       - authenticating a user via a user ID and password;

       - tracking URLs visited;

       - managing the display of advertising banners;

       - targeting advertising based on URL visited and on keyword search;

       - logging the number of times an ad was shown and the number of times an
         ad was clicked on;

       - monitoring the quality of the online session (including dial-up and
         network errors); and

       - providing a mechanism for customer feedback.

    We intend to continue to extend the functionality of The ZeroPort to enhance
our users' experience. Features under development include:

       - short-cut buttons to content sites;

                                       41
<PAGE>
       - an information ticker for stocks, weather, sports and news;

       - a new message indicator; and

       - rich media support.

    The zCast Client is a JAVA application that runs on a user's personal
computer. Using JAVA affords us the ability to run on multiple operating systems
with minimal code changes. In addition to JAVA, native Microsoft Windows
applications and system files are used to extend the functionality of the zCast
Client. The zCast Client currently operates on the Windows 95, Windows 98 and
Windows NT 4.x operating systems. We also plan to operate on the Apple Macintosh
operating system in the future.

    THE ZCAST SERVER NETWORK

    The zCast Server network is a group of back-end software applications
running on multiple servers that manage and collect important data relating to
each user's online session. The servers consist of the following components:

    APPLICATION SERVER. The application server software interacts with The
ZeroPort to send and receive information such as authentication, playlists of
advertisements and impression and click counts. This proprietary software is
written in JAVA, which helps make interaction between The ZeroPort and the
server seamless and robust. The application server also takes advantage of
software and hardware load balancing, both of which enhance the scalability of
the system.

    DATABASE SERVER. The database server stores session information, user
information and ad display and click counts. This server is based on Oracle
database technology and is designed by NetZero to handle very large volumes of
data.

    AD SERVER. The ad server manages the ad inventory and determines which ads
users will view during their online session. This server is based on NetGravity
technology and has been customized by NetZero to create a playlist of
advertising banners for each online session. The implementation of the
NetGravity ad server has been further customized to significantly improve its
performance and scalability.

    All of the above components run on Sun Microsystems' servers and are
connected to disk arrays. These provide NetZero with the ability to quickly
scale and improve overall system performance.

    We are in the process of implementing a multiple "cell" architecture to
enhance the scalability of the zCast Server network. Each cell, which will
operate independently of other cells, will consist of application servers,
database servers and ad servers and is being designed to handle two to three
million users, based on current average usage. Once implemented, we intend to
balance traffic across different cells based on capacity, providing us with a
fault-tolerant infrastructure.

    As part of our free Internet service, we provide industry standard POP3
e-mail accounts for our registered users. POP3 e-mail can be accessed by most
popular e-mail client software applications such as Microsoft Outlook Express.
Our e-mail servers run Qmail software in a Sun Sparc Solaris environment. We
have modified and continue to modify the Qmail server software to provide the
capacity to service millions of users. We have placed rigorous anti-spamming
mechanisms in place on our e-mail servers to limit abuses of our free e-mail
service.

COMMUNICATIONS NETWORK

    To use our services, users initiate telephone connections between their
personal computers and computer hardware in local or regional telecommunications
facilities known as POPs. We contract for the use of POPs around the country
from various wholesale providers, including GTE

                                       42
<PAGE>
Internetworking, Level 3 Communications, NaviNet and Apex Global Information
Systems. These providers also carry our data between their POPs and our central
computers in Los Angeles, California. Through our network providers, we are able
to offer local dial-up phone numbers in over 1,100 cities across the United
States. Thus, our users typically bear no expenses for communication beyond the
cost, if any, of an ordinary local or regional phone call. Our service provides
full Point-to-Point Protocol (PPP) access to the Internet, and supports the v.90
standard for 56 kbps connections and ISDN in certain areas. We continuously
monitor network service levels around the country and work with our partners to
help maintain high levels of network availability and throughput for our users.

    Our zCast and e-mail servers reside at a co-location facility provided by
Level 3 Communications in Los Angeles, California. We are in the process of
building our own data center at our offices in Westlake Village, California,
which will be equipped with battery and generator power backup systems to
prevent outages from interruption of utility power to the building. When the
data center is complete, we will also install zCast and e-mail servers at that
facility.

COMPETITION

    We compete for users and advertising customers.

    COMPETITION FOR USERS

    We believe that the primary competitive factors determining success in the
market for Internet users include a reputation for reliability of service,
effective customer support, pricing, easy-to-use software, geographic coverage
and scope of services. Other important factors include the timing and
introduction of new products and services and industry as well as general
economic trends. While we believe that we compete favorably with respect to
these factors, numerous of our competitors may have an advantage over us with
respect to specific factors. We currently compete with established online
service and content providers, such as America Online and The Microsoft Network,
independent national ISPs such as EarthLink, MindSpring and Prodigy, and
numerous regional and local commercial ISPs. Certain of these providers offer
significantly greater customer support and scope of services than we currently
offer. We also compete against other companies that offer free Internet access
services or free products, such as PCs, bundled with, or as promotions for,
access services, and expect that more companies will begin to offer such
services or products in the future. We also compete with, and expect increased
competition from, telecommunications service providers, such as AT&T, GTE and
MCI WorldCom. These companies generally have far greater resources, distribution
channels and brand awareness as well as lower costs because they control the
telecommunications services we are required to purchase. This cost advantage,
which could result in significant discounts to the user, could significantly
increase competitive pressures on us. We also believe that new competitors,
including large computer hardware and software, media and telecommunications
companies, will continue to enter the Internet access market and that our
competition will increase as large diversified telecommunications and media
companies acquire ISPs and as ISPs consolidate into larger, more competitive
companies. Diversified competitors may also bundle other services and products
with Internet connectivity services, potentially placing us at a significant
competitive disadvantage.

    We also face competition from companies that provide broadband connections
to users' homes, including local and long-distance telephone companies, cable
television companies, electric utility companies, and wireless communications
companies. These companies may use broadband technologies to include Internet
access or business services such as Web hosting in their basic bundle of
services or may offer Internet access or business services for little or no
additional charge. Broadband technologies enable users to access the Internet at
much faster speeds than the dial-up service we currently offer. While the market
for such broadband technologies is still

                                       43
<PAGE>
emerging, we believe it will continue to grow and pose an increasingly
significant source of competition.

    COMPETITION FOR ADVERTISING CUSTOMERS

    We believe that the primary competitive factors determining success in the
market for advertising customers include the size and demographic profile of a
user base, the ability to target users based on specific demographic criteria,
pricing and geographic coverage. While we believe that we compete favorably with
respect to these factors, numerous of our competitors may have an advantage over
us with respect to specific factors. We compete for Internet advertising and
sponsorship revenues with certain major ISPs, content providers, large Web
publishers, Web search engine and portal companies, Internet advertising
providers, content aggregation companies, and various other companies which
facilitate Internet advertising. Many of these companies have longer operating
histories, greater name recognition, larger user bases and significantly greater
financial, technical and marketing resources than we do. This may allow them to
respond more quickly than we can to new or emerging technologies and changes in
advertiser requirements. It may also allow them to devote greater resources than
we can to the development, promotion and sale of their products and services.
Such competitors may also engage in more extensive research and development,
undertake more far-reaching marketing campaigns, adopt more aggressive pricing
policies and make more attractive offers to existing and potential employees,
strategic partners, advertisers and Web publishers. In addition, current and
potential competitors have established or may establish cooperative
relationships among themselves or with third parties to increase the ability of
their products or services to address the needs of our prospective advertising
and sponsorship customers. Increased competition is likely to result in price
reductions, reduced gross margins and loss of market share. We also compete with
television, radio, cable and print media for a share of advertisers' total
advertising budgets.

INTELLECTUAL PROPERTY

    Our success and ability to compete are substantially dependent on our
internally developed technologies and trademarks, which we protect through a
combination of patent, copyright, trade secret and trademark law. We have filed
four patent applications relating to NetZero's techniques for delivering
advertisements on computer desktops.

    We generally enter into confidentiality or license agreements with our
employees, consultants and corporate partners, and generally control access to
and distribution of our technologies, documentation and other proprietary
information. Despite our efforts to protect our proprietary rights from
unauthorized use or disclosure, parties may attempt to disclose, obtain or use
NetZero's solutions or technologies. We cannot be certain that the steps we have
taken will prevent misappropriation of our solutions or technologies,
particularly in foreign countries where the laws or law enforcement may not
protect our proprietary rights as fully as in the United States. We have
licensed, and may license in the future, elements of our trademarks, trade dress
and similar proprietary right to third parties. While we attempt to ensure that
the quality of our brand is maintained by such business partners, such partners
may take actions that could materially and adversely affect the value of our
proprietary rights or reputation.

    Our zCast technology collects and utilizes data derived from our user
activity. This data is used for ad targeting and measuring ad performance.
Although we believe that we have the right to use such data, there can be no
assurance that third parties will not assert claims against us for using such
information. In addition, others may claim rights to such information. We may
also be required, upon request, to delete "identifying information" of users
under the age of 18.

    We cannot be certain that any of our proprietary rights will be viable or of
value in the future since the validity, enforceability and scope of protection
of certain proprietary rights in Internet-

                                       44
<PAGE>
related industries is uncertain and still evolving. In particular, there can be
no assurance that any of our patent, copyright or trademark applications, now
pending or to be filed in the future, will be approved. Even if they are
approved, such patents, trademarks or copyrights may be successfully challenged
by others or invalidated. If our trademark registrations are not approved
because third parties own such trademarks, our use of the trademarks will be
restricted unless we enter into arrangements with such third parties. These
arrangements may not be available on commercially reasonable terms.

    Furthermore, third parties may assert infringement claims against us. From
time to time we may be subject to claims in the ordinary course of our business,
including claims of alleged infringement of the trademarks, patents and other
intellectual property rights of third parties by us or our users. Any such
claims, or any resultant litigation, should it occur, could subject us to
significant liability for damages and could result in the invalidation of our
proprietary rights. In addition, even if we were to win any such litigation,
such litigation could be time-consuming and expensive to defend, and could
result in the diversion of our time and attention, any of which could materially
and adversely affect our business, results of operations and financial
condition. Any claims or litigation may also result in limitations on our
ability to use such trademarks, patents and other intellectual property unless
we enter into arrangement with such third parties, which may be unavailable on
commercially reasonable terms.

PRIVACY POLICY

    We believe that issues relating to the privacy of Internet users and the use
of personal information about these users are critically important as the
Internet and its commercial use grow. We have adopted and disclosed to our users
a detailed policy outlining the permissible uses of information about users and
the extent to which such information may be shared with others. Our users must
acknowledge and agree to this policy when registering to use our service. We do
not sell or license to third parties any personally identifiable information
about users unless they specifically authorize us to do so. However, we do use
information about users to improve the effectiveness of advertising by our
advertising customers. We are a member of the TRUSTe program, an independent
non-profit organization that audits the privacy statements of Web-sites and
their adherence to those privacy statements.

EMPLOYEES

    As of June 30, 1999, we employed 116 persons, including 22 in sales and
marketing, 20 in customer care, 33 in product development, 15 in information
systems and 26 in finance, accounting and administration. None of our employees
are subject to any collective bargaining agreement.

FACILITIES

    Our principal executive offices are located in a 48,000 square feet facility
in Westlake Village, California under a lease expiring in March 2009. We also
have leased space for our sales and marketing efforts in San Francisco and New
York. We are continually evaluating our facilities requirements.

LEGAL PROCEEDINGS

    We are not a party to any material legal proceedings.

BOARD OF DIRECTORS

    Our board of directors currently comprises seven directors. Directors are
elected by the stockholders at each annual meeting of stockholders and serve for
one year or until their successors are duly elected and qualified. However, our
certificate of incorporation provides that, following the offering, our board of
directors will be divided into three classes as nearly equal in size as possible
with staggered, three-year terms. The term of office of our Class I directors
will expire at the annual meeting of stockholders to be held in 2000; the term
of office of our Class II directors will expire at the annual meeting of
stockholders to be held in 2001; and the term of office of our Class III
directors will expire at the annual meeting of the stockholders to be held in
2002. At each annual meeting of the stockholders, beginning with the 2000 annual
meeting, the successors to the directors whose terms will then expire will be
elected to serve from the time of their election and qualification until the
third annual meeting following their election or until their successors have
been duly elected and qualified, or until their earlier resignation or removal,
if any. Messrs. Bohnett and Koontz have been designated as Class I directors;
Mr. Burr and Ms. Fonstad have been designated as Class II directors; and Messrs.
Armstrong, Goldston and Gross have been designated as Class III directors. The
classification of our board of directors could have the effect of making it more
difficult for a third party to acquire, or of discouraging a third party from
acquiring, control of NetZero.

BOARD COMMITTEES

    The board has established an audit committee to meet with and consider
suggestions from members of management and our internal accounting personnel, as
well as our independent accountants, concerning our financial operations. The
audit committee also has the responsibility to review our audited financial
statements and consider and recommend the employment of, and approve the fee
arrangements with, independent accountants for both audit functions and for
advisory and other consulting services. The audit committee is currently
comprised of Messrs. Armstrong and Bohnett and Ms. Fonstad. The board has also
established a compensation committee to review and make recommendations to the
board regarding the compensation and benefits for our key executive officers,
administer our stock purchase, equity incentive and stock option plans. The
compensation committee is currently comprised of Messrs. Armstrong, Gross and
Koontz.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

    None of the members of the compensation committee is or has been an employee
of ours at any time since our formation. None of our executive officers serves
as a member of the board of directors or compensation committee of any entity
that has one or more executive officers serving as a member of our board of
directors or compensation committee.

DIRECTOR COMPENSATION AND OTHER ARRANGEMENTS

    Our directors receive no cash remuneration for serving on the board of
directors or any board committee; however, directors are reimbursed for all
reasonable expenses incurred by them in attending board and committee meetings.
In December 1998, David C. Bohnett was granted an option to purchase 225,000
shares of Series C preferred stock at an exercise price of $0.4297. The

                                       50
<PAGE>
options vest ratably over a four year period. Mr. Bohnett also purchased 101,260
shares of NetZero's Series B preferred stock in January 1999 for an aggregate
purchase price of $15,000.

    Certain non-employee directors may also receive option grants and other
equity incentives under our new 1999 Stock Incentive Plan, including the
director fee option grant programs in effect under that plan. See "--1999 Stock
Incentive Plan" below.

    Employee directors are also eligible to receive stock option grants and
direct issuances of common stock under our 1999 Stock Incentive Plan. See
"--1999 Stock Incentive Plan".

EXECUTIVE COMPENSATION

    The following summary compensation table sets forth information concerning
cash and non-cash compensation earned during the fiscal year ended June 30, 1999
by our current Chief Executive Officer, and one other executive officer who
acted as our chief executive officer during the fiscal year ended June 30, 1999

    In addition to the above named executive officers for the fiscal year ended
June 30, 1999, NetZero currently employs certain other executive officers who it

President, Sales (annual salary of $135,000) and Frederic A. Randall, Jr.,

                 STOCK OPTIONS GRANTED DURING FISCAL YEAR 1999

    The following table sets forth certain information regarding options to
purchase common stock granted to named executive officers during the fiscal year
ended June 30, 1999 including the potential realizable value over the ten-year
term of the options, based on assumed, annually compounded rates of stock value
appreciation. These assumed rates of appreciation 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. No stock appreciation rights were
granted to such individuals during such year.

(1) All options were granted at an exercise price which our board of directors
    believed to be equal to the fair market value of our common stock on the
    date of grant. Based upon a subsequent review, we determined the deemed fair
    value of the common stock for financial accounting purposes to be as
    reflected in the "Market Value at Date of Grant" column. The amount shown in
    the "0%" column reflects the difference between the exercise price and the
    deemed fair market value as of the date of option grant, as determined in
    our subsequent review.

EMPLOYMENT AGREEMENTS AND CHANGE IN CONTROL ARRANGEMENTS

    Mark R. Goldston entered into a four-year employment agreement, effective as
of March 20, 1999, pursuant to which Mr. Goldston serves as our Chief Executive
Officer and Chairman. Pursuant to this agreement, Mr. Goldston receives a base
salary of $200,000 per year and during the first two years of the agreement, Mr.
Goldston receives a guaranteed bonus of $200,000 per year, payable in four
quarterly installments. Mr. Goldston is also entitled to receive a signing bonus
of $300,000 payable on January 1, 2000 so long as he is employed by us on such
date. In addition, we gave Mr. Goldston benefits that we make available to our
employees in comparable positions, and we granted Mr. Goldston an immediately
exercisable option to purchase 6,286,383 shares of our common stock. Mr.
Goldston exercised his option to purchase common stock in full, however, the
option shares are subject to repurchase by us at the price paid for such shares.
Our repurchase right lapses pursuant to a forty-eight equal monthly vesting
schedule. If Mr. Goldston's employment is terminated by us without cause, or if
following a change in control of NetZero, Mr. Goldston resigns for certain
specified reasons, he will be entitled to receive a $1,000,000 lump sum
severance payment. In addition, if Mr. Goldston's employment is terminated by us
without cause within the first year of his employment, an additional 25% of his
option shares of common stock will

                                       52
<PAGE>
vest, and if his employment is terminated by us without cause following the
first year of his employment, all of his shares will vest. Mr. Goldston will
also be credited with an additional twenty-four months of vesting on his option
shares in the event his employment is terminated by reason of death or permanent
disability. Further, Mr. Goldston's option shares automatically vest upon a
change in control of NetZero.

    Charles S. Hilliard entered into a four-year employment agreement, effective
as of April 17, 1999, pursuant to which Mr. Hilliard serves as Senior Vice
President, Finance and Chief Financial Officer. Pursuant to this agreement, Mr.
Hilliard receives a base salary of $140,000 plus a performance-based bonus of up
to 50% of his base salary. In addition, we gave Mr. Hilliard benefits that we
make available to our employees in comparable positions, and we granted Mr.
Hilliard an immediately exercisable option to purchase 1,200,000 shares of our
common stock at a price per share of $0.33. Mr. Hilliard exercised his option to
purchase common stock in full, however, such option shares are subject to
repurchase by us at the price paid for such shares. Our repurchase right lapses
with respect to 25% of the option shares upon the one-year anniversary of Mr.
Hilliard's employment and with respect to the remaining 75% of the option shares
over 36 equal monthly installments thereafter. We also agreed to sell 225,000
shares of our Series D preferred stock to Mr. Hilliard at a price per share of
$1.84. Mr. Hilliard's employment is subject to termination at any time by him or
by us. If Mr. Hilliard's employment is terminated without cause, he will be
entitled to receive a lump sum payment of $280,000 and shall be credited with an
additional twelve months of vesting on his option shares. Mr. Hilliard will also
be credited with an additional twelve months of vesting on his option shares in
the event his employment is terminated by reason of death or permanent
disability. If, following a change in control, Mr. Hilliard's employment is
terminated without cause or is constructively terminated, all of the option
shares shall vest immediately; provided, if such change in control occurs on or
prior to January 17, 2000, only 75% of the option shares shall vest.

    Frederic A. Randall, Jr. entered into a four-year employment agreement,
effective as of March 20, 1999, pursuant to which Mr. Randall serves as a Senior
Vice President and our General Counsel. Pursuant to this Agreement, Mr. Randall
receives a base salary of $135,000 plus a performance-based bonus of up to 50%
of his base salary. In addition, we gave Mr. Randall benefits that we make
available to our employees in comparable positions, and we granted Mr. Randall
an immediately exercisable option to purchase 1,050,000 shares of our common
stock at a price per share of $0.10. Mr. Randall exercised his option to
purchase common stock in full, however, the option shares are subject to
repurchase by us at the price paid for such shares. Our repurchase right lapses
with respect to 25% of the option shares upon the one-year anniversary of Mr.
Randall's employment and with respect to the remaining 75% of the option shares
over 36 equal monthly installments thereafter. Mr. Randall's employment is
subject to termination at any time by him or by us. If Mr. Randall's employment
is terminated without cause, he will be entitled to receive a lump sum payment
of $270,000 and shall be credited with an additional twelve months of vesting on
his option shares. Mr. Randall will also be credited with an additional twelve
months of vesting on his option shares in the event his employment is terminated
by reason of death or permanent disability. If, following a change in control,
Mr. Randall's employment is terminated without cause or is constructively
terminated, all of the option shares shall vest immediately; provided, if such
change in control occurs on or prior to December 19, 1999, only 75% of the
option shares shall vest.

    Our 1999 Stock Incentive Plan includes change in control provisions which
may result in the accelerated vesting of outstanding option grants and stock
issuances. See "--1999 Stock Incentive Plan--Change in Control".

                                       53

1999 STOCK INCENTIVE PLAN

    The 1999 Stock Incentive Plan is the successor program to our existing stock
option/stock issuance plans. The new 1999 Stock Incentive Plan was adopted by
the board in July 1999 and we expect that it will be submitted to the
stockholders for their approval prior to the closing of this offering. If
approved by the stockholders, the 1999 Stock Incentive Plan will become
effective upon the closing of this offering. At that time, all outstanding
options under our existing stock option/ stock issuance plan will be transferred
to the 1999 Stock Incentive Plan, and no further option grants will be made
under that plan. The transferred options will continue to be governed by their
existing terms, unless our compensation committee decides to extend one or more
features of the 1999 Stock Incentive Plan to those options. Except as otherwise
noted below, the transferred options have substantially the same terms as will
be in effect for grants made under the discretionary option grant program or our
1999 Stock Incentive Plan.

    SHARE RESERVE.  Under the 1999 Stock Incentive Plan, 21.9 million shares of
our common stock have been authorized for issuance. This share reserve consists
of the shares that will be carried over from our existing stock option/stock
issuance plans, including the shares subject to outstanding options under these
plans, plus an additional increase of approximately 2.4 million shares. The
share reserve under our 1999 Stock Incentive Plan will automatically increase on
the first trading day in January of each year, beginning with calendar year
2000, by an amount equal to 3% of the total number of shares of our common stock
outstanding on the last trading day in December in the prior year. In addition,
no participant in the 1999 Stock Incentive Plan may be granted stock options or
direct stock issuances for more than 2 million shares of common stock in total
in any calendar year.

    PROGRAMS.  Our 1999 Stock Incentive Plan has four separate programs:

       - the discretionary option grant program, under which eligible
         individuals in our employ may be granted options to purchase shares of
         our common stock at an exercise price not less than the fair market
         value of those shares on the grant date;

       - the stock issuance program, under which eligible individuals may be
         issued shares of common stock directly, upon the attainment of
         performance milestones or the completion of a specified service period
         or as a bonus for past services;

       - the salary investment option grant program, under which our executive
         officers and other highly compensated employees may be given the
         opportunity to apply a portion of their base salary each year to the
         acquisition of special below market stock option grants; and

       - the director fee option grant program, under which our non-employee
         board members may be given the opportunity to apply a portion of any
         retainer fee otherwise payable to them in cash for the year to the
         acquisition of special below-market option grants.

    ELIGIBILITY.  The individuals eligible to participate in our 1999 Stock
Incentive Plan include our officers and other employees, our board members and
any consultants we hire.

    ADMINISTRATION.  The discretionary option grant and stock issuance programs
will be administered by our compensation committee. This committee will
determine which eligible individuals are to receive option grants or stock
issuances under those programs, the time or times when the grants or issuances
are to be made, the number of shares subject to each grant or issuance, the
status of any granted option as either an incentive stock option or a
nonstatutory stock option under the federal tax laws, the vesting schedule to be
in effect for the option grant or stock issuance and the maximum term for which
any granted option is to remain outstanding. The compensation committee will
also have the authority to select the executive officers and other

                                       54
<PAGE>
highly compensated employees who may participate in the salary investment option
grant program in the event that program is put into effect for one or more
calendar years.

    PLAN FEATURES.  Our 1999 Stock Incentive Plan will include the following
features:

       - The exercise price for any options granted pursuant to the plan may be
         paid in cash or in shares of our common stock valued at fair market
         value on the exercise date. The option may also be exercised through a
         same-day sale program without any cash outlay by the optionee.

       - The compensation committee will have the authority to cancel
         outstanding options under the discretionary option grant program,
         including any transferred options from our existing stock option/stock
         issuance plan, in return for the grant of new options for the same or
         different number of option shares with an exercise price per share
         based upon the fair market value of our common stock on the new grant
         date.

       - Stock appreciation rights may be issued under the discretionary option
         grant program. These rights will provide the holders with the election
         to surrender their outstanding options for a payment from us equal to
         the fair market value of the shares subject to the surrendered options
         less the exercise price payable for those shares. We may make the
         payment in cash or in shares of our common stock. None of the
         outstanding options under our existing stock option/stock issuance plan
         have any stock appreciation rights.

    CHANGE IN CONTROL.  The 1999 Stock Incentive Plan will include the following
change in control provisions which may result in the accelerated vesting of
outstanding option grants and stock issuances:

       - In the event that we are acquired by merger or asset sale, each
         outstanding option under the discretionary option grant program which
         is not to be assumed by the successor corporation will immediately
         become exercisable for all the option shares, and all outstanding
         unvested shares will immediately vest, except to the extent our
         repurchase rights with respect to those shares are to be assigned to
         the successor corporation.

       - The compensation committee will have complete discretion to grant one
         or more options which will become exercisable for all the option shares
         in the event those options are assumed in the acquisition but the
         optionee's service with us or the acquiring entity is subsequently
         terminated. The vesting of any outstanding shares under our 1999 Stock
         Incentive Plan may be accelerated upon similar terms and conditions.

       - The compensation committee may grant options and structure repurchase
         rights so that the shares subject to those options or repurchase rights
         will immediately vest in connection with a successful tender offer for
         more than fifty percent of our outstanding voting stock or a change in
         the majority of our board through one or more contested elections. Such
         accelerated vesting may occur either at the time of such transaction or
         upon the subsequent termination of the individual's service.

       - The options outstanding under our existing stock option/stock issuance
         plan will immediately vest in the event we are acquired and the
         acquiring company does not assume those options. In addition, any
         options which are so assumed will vest in whole or in part on an
         accelerated basis upon an involuntary termination of the optionee's
         employment within 12 months after the acquisition. In general, the
         terminated optionees shall vest in the greater of (a) 25% of their
         option grant or (b) the

                                       55
<PAGE>
         number of option shares which they would have vested in had their
         employment been for twice their actual period of service prior to the
         time of such involuntary termination.

    SALARY INVESTMENT OPTION GRANT PROGRAM.  In the event the compensation
committee decides to put this program into effect for one or more calendar
years, each of our executive officers and other highly compensated employees may
elect to reduce his or her base salary for the calendar year by an amount not
less than $10,000 nor more than $50,000. Each selected individual who makes such
an election will automatically be granted, on the first trading day in January
of the calendar year for which his or her salary reduction is to be in effect,
an option to purchase that number of shares of common stock determined by
dividing the salary reduction amount by two-thirds of the fair market value per
share of our common stock on the grant date. The option will have an exercise
price per share equal to one-third of the fair market value of the option shares
on the grant date. As a result, the option will be structured so that the fair
market value of the option shares on the grant date less the exercise price
payable for those shares will be equal to the amount of the salary reduction.
The option will become exercisable in a series of twelve equal monthly
installments over the calendar year for which the salary reduction is to be in
effect.

    DIRECTOR FEE OPTION GRANT PROGRAM.  If this program is put into effect in
the future, then each non-employee board member may elect to apply all or a
portion of any cash retainer fee for the year to the acquisition of a
below-market option grant. The option grant will automatically be made on the
first trading day in January in the year for which the non-employee board member
would otherwise be paid the cash retainer fee in the absence of his or her
election. The option will have an exercise price per share equal to one-third of
the fair market value of the option shares on the grant date, and the number of
shares subject to the option will be determined by dividing the amount of the
retainer fee applied to the program by two-thirds of the fair market value per
share of our common stock on the grant date. As a result, the option will be
structured so that the fair market value of the option shares on the grant date
less the exercise price payable for those shares will be equal to the portion of
the retainer fee applied to that option. The option will become exercisable in a
series of twelve equal monthly installments over the calendar year for which the
election is in effect. However, the option will become immediately exercisable
for all the option shares upon the death or disability of the optionee while
serving as a board member.

    ADDITIONAL PROGRAM FEATURES.  Our 1999 Stock Incentive Plan will also have
the following features:

       - Outstanding options under the salary investment option grant and
         director fee option grant programs will immediately vest if we are
         acquired by a merger or asset sale or if there is a successful tender
         offer for more than 50% of our outstanding voting stock or a change in
         the majority of our board through one or more contested elections.

       - Limited stock appreciation rights will automatically be included as
         part of each grant made under the salary investment option grant and
         the director fee option grant programs, and these rights may also be
         granted to one or more officers as part of their option grants under
         the discretionary option grant program. Options with this feature may
         be surrendered to us upon the successful completion of a hostile tender
         offer for more than 50% of our outstanding voting stock. In return for
         the surrendered option, the optionee will be entitled to a cash
         distribution from us in an amount per surrendered option share based
         upon the highest price per share of our common stock paid in that
         tender offer.

       - The board may amend or modify the 1999 Stock Incentive Plan at any
         time, subject to any required stockholder approval. The 1999 Stock
         Incentive Plan will terminate no later than July 12, 2009.

1999 EMPLOYEE STOCK PURCHASE PLAN.

    Our 1999 Employee Stock Purchase Plan was adopted by the board in July 1999
and submitted to the stockholders for their approval in July, 1999. We expect
the plan to become effective immediately upon the signing of the underwriting
agreement for this offering. The plan is designed to allow our eligible
employees and the eligible employees of our participating subsidiaries to
purchase shares of common stock, at semi-annual intervals, with their
accumulated payroll deductions.

    SHARE RESERVE.  500,000 shares of our common stock will initially be
reserved for issuance. The reserve will automatically increase on the first
trading day in January each year, beginning in calendar year 2000, by an amount
equal to the lower of (a) one and one half percent (1.5%) of the total number of
outstanding shares of our common stock on the last trading day in December in
the prior year and (b) the number of shares approved by the board for each
calendar year.

    OFFERING PERIODS.  The plan will have a series of successive offering
periods, each with a maximum duration of 24 months. The initial offering period
will start on the date the underwriting agreement for the offering is signed and
will end on the last business day in October 2001. The next offering period will
start on the first business day in November 2001, and subsequent offering
periods will be set by our compensation committee.

    ELIGIBLE EMPLOYEES.  Individuals scheduled to work more than 20 hours per
week for more than 5 calendar months per year may join an offering period on the
start date or any semi-annual entry date within that period. Semi-annual entry
dates will occur on the first business day of May and November each year.
Individuals who become eligible employees after the start date of an offering
period may join the plan on any subsequent semi-annual entry date within that
offering period.

    PAYROLL DEDUCTIONS.  A participant may contribute up to 15% of his or her
cash earnings through payroll deductions, and the accumulated deductions will be
applied to the purchase of shares on each semi-annual purchase date. The
purchase price per share will be equal to 85% of the fair market value per share
on the participant's entry date into the offering period or, if lower, 85% of
the fair market value per share on the semi-annual purchase date. Semi-annual
purchase dates will occur on the last business day of April and October each
year. In no event, however, may any participant purchase more than 5,000 shares
on any purchase date, and not more than 250,000 shares may be purchased in total
by all participants on any purchase date. Our compensation committee may
increase or decrease these limits prior to the start of any new offering period
under the plan.

    RESET FEATURE.  If the fair market value per share of our common stock on
any purchase date is less than the fair market value per share on the start date
of the two-year offering period, then that offering period will automatically
terminate, and a new two-year offering period will begin on the next business
day. All participants in the terminated offering will be transferred to the new
offering period.

    CHANGE IN CONTROL.  Should we be acquired by merger or sale of substantially
all of our assets or more than fifty percent of our voting securities, then all
outstanding purchase rights will automatically be exercised immediately prior to
the effective date of the acquisition. The purchase price will be equal to 85%
of the market value per share on the participant's entry date into the offering
period in which an acquisition occurs or, if lower, 85% of the fair market value
per share immediately prior to the acquisition.

    PLAN PROVISIONS.  The following provisions will also be in effect under the
plan:

       - The plan will terminate no later than the last business day of October
         2009.

                                       57
<PAGE>
       - The board may at any time amend, suspend or discontinue the plan.
         However, certain amendments may require stockholder approval.

LIMITATION ON LIABILITY AND INDEMNIFICATION MATTERS

    The certificate of incorporation that we will adopt immediately prior to the
closing of this offering provides that, except to the extent prohibited by the
Delaware General Corporation Law, our directors will not be personally liable to
us or our stockholders for monetary damages for any breach of fiduciary duty as
directors. Under the Delaware General Corporation Law, the directors have a
fiduciary duty to NetZero which is not eliminated by this provision of the
certificate of incorporation and, in appropriate circumstances, equitable
remedies such as injunctive or other forms of nonmonetary relief will remain
available. In addition, each director will continue to be subject to liability
under the Delaware law for breach of the director's duty of loyalty, for acts or
omissions which are found by a court of competent jurisdiction to be not in good
faith or which involve intentional misconduct, or knowing violations of law, for
actions leading to improper personal benefit to the director, and for payment of
dividends or approval of stock repurchases or redemptions that are prohibited by
Delaware law. This provision also does not affect the director's
responsibilities under any other laws, such as the federal securities laws or
state or federal environmental laws. We have obtained liability insurance for
our officers and directors.

    Section 145 of the Delaware law empowers a corporation to indemnify its
directors and officers and to purchase insurance with respect to liability
arising out of their capacity or status as directors and officers, provided that
this provision shall not eliminate or limit the liability of a director: (a) for
any breach of the director's duty of loyalty to the corporation or its
stockholders, (b) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (c) arising under Section
174 of the Delaware law, or (d) for any transaction from which the director
derived an improper personal benefit. The Delaware law provides further that the
indemnification permitted thereunder shall not be deemed exclusive of any other
rights to which the directors and officers may be entitled under the
corporation's bylaws, any agreement, a vote of stockholders or otherwise. The
certificate of incorporation provides that we shall, to the fullest extent
permitted by the Delaware law, indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding (whether civil, criminal, administrative or investigative) by
reason of the fact that such person is or was a director or officer, or is or
was serving at our request as a director or officer of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise,
against expenses (including attorneys' fees), judgements, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding.

    We have entered into indemnification agreements with our directors and
certain of our officers containing provisions that may require us, among other
things, to indemnify such directors and officers against certain liabilities
that may arise by reason of their status or service as directors or officers
(other than liabilities arising from willful misconduct of a culpable nature),
to advance their expenses incurred as a result of any proceeding against them as
to which they could be indemnified, and to obtain directors' and officers'
liability insurance if maintained for other directors or officers.

    At present, there is no pending litigation or proceeding involving any
director, officer, employee or agent as to which indemnification will be
required or permitted. We are not aware of any threatened litigation or
proceeding which may result in a claim for such indemnification.

                             PRINCIPAL STOCKHOLDERS

    The following table sets forth information with respect to the beneficial
ownership of our common stock as of June 30, 1999:

       - each stockholder whom we know to beneficially own 5% or more of the
         outstanding shares of common stock;

       - each of our directors and named executive officers; and

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

The information set forth in the table below gives effect to the conversion of
all issued and outstanding convertible preferred stock. Unless otherwise
indicated, the address of each beneficial owner listed below is c/o NetZero,
Inc., 2555 Townsgate Road, Westlake Village, California.

    Beneficial ownership is determined in accordance with the rules of the
Securities and Exchange Commission and generally includes voting or investment
power with respect to securities. Except as indicated by the footnotes below, we
believe, based on information furnished to us, that the persons and entities
named in the table below have sole voting and investment power with respect to
all shares of common stock shown as beneficially owned by them. Percentage of
beneficial ownership is based on 93,036,410 shares of common stock outstanding
as of June 30, 1999, and       shares of common stock outstanding after the
completion of this offering. In computing the number of shares of common stock
subject to options held by that person that are exercisable within 60 days of
June 30, 1999, these shares are deemed outstanding for the purpose of
determining the percentage ownership of the optionee. These shares, however, are
not deemed outstanding for the purpose of computing the percentage ownership of
any other stockholder.

outstanding and held of record by 163 stockholders (assuming conversion of all
shares of preferred stock into common stock). Based on the number of shares
outstanding as of that date and giving effect to the issuance of the
shares of common stock offered by us hereby, there will be              shares
of common stock outstanding (assuming no exercise of the underwriters'
over-allotment option) upon the closing of the offering.

    Holders of the common stock are entitled to one vote for each share held on
all matters submitted to a vote of the stockholders. Holders of common stock are
entitled to receive ratably any dividends that may be declared by the Board of
Directors out of legally available funds, subject to any preferential dividend
rights of any outstanding preferred stock. Upon our liquidation, dissolution or
winding up, the holders of common stock are entitled to receive ratably our net
assets available after the payment of all debts and other liabilities and
subject to the prior rights of any outstanding preferred stock. Holders of
common stock have no preemptive, subscription, redemption or conversion rights.
The outstanding shares of common stock are, and the shares offered by us in this
offering will be upon receipt of payment for such shares, fully paid and
nonassessable. The rights, preferences and privileges of holders of common stock
are subject to, and may be adversely affected by, the rights of holders of
shares of any series of preferred stock which we may designate and issue in the
future without further stockholder approval. Upon the closing of the offering,
there will be no shares of preferred stock outstanding.

PREFERRED STOCK

    Upon the closing of this offering, all outstanding shares of our Series A,
Series B, Series C and Series D preferred stock will convert into shares of
common stock. Thereafter, the board of directors will be authorized without
further stockholder approval to issue from time to time up to an aggregate of
10,000,000 shares of preferred stock in one or more series and to fix or alter
the designations, preferences, rights, qualifications, limitations or
restrictions of the shares of each such series, including the dividend rights,
dividend rates, conversion rights, voting rights, term of redemption (including
sinking fund provisions), redemption price or prices, liquidation preferences
and the number of shares constituting any series or designations of such series
without further vote or action by the stockholders. The issuance of preferred
stock may have the effect of delaying, deferring or preventing a change in
control of our management without further action by the stockholders and may
adversely affect the voting and other rights of the holders of common stock. The
issuance of preferred stock with voting and conversion rights may adversely
affect the voting power of the holders of common stock, including the loss of
voting control to others. We have no present plans to issue any shares of
preferred stock.

ANTI-TAKEOVER EFFECTS OF PROVISIONS OF DELAWARE LAW AND OUR CERTIFICATE OF
INCORPORATION AND BYLAWS

    Certain provisions of our certificate of incorporation and bylaws, which
will become effective upon the closing of this offering, may make it more
difficult to acquire control of NetZero by various means. These provisions could
deprive the stockholders of opportunities to realize a premium on the shares of
common stock owned by them. In addition, these provisions may adversely affect
the prevailing market price of the stock. These provisions are intended to (a)
enhance the likelihood of continuity and stability in the composition of the
board and in the policies formulated by the board, (b) discourage certain types
of transactions which may involve an actual or threatened change in control of
NetZero, (c) discourage certain tactics that may be used in proxy fights, (d)
encourage persons seeking to acquire control of NetZero to consult first with
the board of directors to negotiate the terms of any proposed business
combination or offer, and (e) reduce our vulnerability to an unsolicited
proposal for a takeover that does not contemplate the acquisition of all
outstanding shares of NetZero or that is otherwise unfair to our stockholders.

    CLASSIFIED BOARD OF DIRECTORS; REMOVAL; FILLING VACANCIES AND
AMENDMENT.  The certificate and bylaws provide that upon the closing of this
offering the board shall be divided into three classes of directors serving
staggered, three-year terms. The classification of the board has the effect of
requiring at least two annual stockholder meetings, instead of one, to replace a
majority of members of the board. Subject to the rights of the holders of any
outstanding series of preferred stock, the certificate authorizes only the board
to fill vacancies, including newly created directorships. Accordingly, this
provision could prevent a stockholder from obtaining majority representation on
the board by enlarging the board of directors and filling the new directorships
with its own nominees. The certificate also provides that directors may be
removed by stockholders only for cause and only by the affirmative vote of
holders of two-thirds of the outstanding shares of voting stock.

    STOCKHOLDER ACTION; SPECIAL MEETING OF STOCKHOLDERS.  The certificate
provides that stockholders may not take action by written consent, but may only
take action at duly called annual or special meetings of stockholders. The
certificate further provides that special meetings of our stockholders may be
called only by the chairman of the board of directors or a majority of the board
of directors. A special meeting may not be held absent such a written request.
The request shall state the purpose or purposes of the proposed meeting. This
limitation on the right of stockholders to call a special meeting could make it
more difficult for stockholders to initiate actions that are opposed by the
board of directors. These actions could include the removal of an incumbent
director or the election of a stockholder nominee as a director. They could also
include the implementation of a rule requiring stockholder ratification of
specific defensive strategies that have been adopted by the board of directors
with respect to unsolicited takeover bids. In addition, the limited ability of
the stockholders to call a special meeting of stockholders may make it more
difficult to change the existing board and management.

    ADVANCE NOTICE REQUIREMENTS FOR STOCKHOLDER PROPOSALS AND DIRECTOR
NOMINATIONS.  The bylaws provide that stockholders seeking to bring business
before an annual meeting of stockholders, or to nominate candidates for election
as directors at an annual meeting of stockholders, must provide timely notice
thereof in writing. To be timely, a stockholder's notice must be delivered to or
mailed and received at our principal executive offices not less than 120 days
prior to the date of our annual meeting. The bylaws also specify certain
requirements as to the form and content of a stockholder's notice. These
provisions may preclude stockholders from bringing matters before an annual
meeting of stockholders or from making nominations for directors at an annual
meeting of stockholders.

                                       65
<PAGE>
    AUTHORIZED BUT UNISSUED SHARES.  The authorized but unissued shares of
common stock and preferred stock are available for future issuance without
stockholder approval. These additional shares may be utilized for a variety of
corporate purposes, including future public offerings to raise additional
capital, corporate acquisitions and employee benefit plans. The existence of
authorized but unissued shares of common stock and preferred stock could render
more difficult or discourage an attempt to obtain control of us by means of a
proxy contest, tender offer, merger or otherwise.

    SUPERMAJORITY VOTE TO AMEND CHARTER AND BYLAWS.  The Delaware General
Corporation Law provides generally that the affirmative vote of a majority of
the shares entitled to vote on any matter is required to amend a corporation's
certificate of incorporation or bylaws, unless a corporation's certificate of
incorporation or bylaws, as the case may be, requires a greater percentage. Our
amended and restated certificate of incorporation imposes supermajority vote
requirements in connection with business combination transactions and the
amendment of certain provisions of our certificate of incorporation and bylaws,
including those provisions relating to the classified board of directors, action
by written consent, the ability of stockholders to call special meetings and the
ability of stockholders to bring business before an annual meeting or to
nominate directors. Following the completion of this offering, our present
directors and executive officers and their respective affiliates will
beneficially own approximately       % of our common stock. This gives them veto
power with respect to any stockholder action or approval requiring either a
two-thirds vote or a simple majority.

    SECTION 203 OF THE DELAWARE GENERAL CORPORATION LAW.  We are subject to the
provisions of Section 203 of the Delaware General Corporation Law, as amended
from time to time. Subject to certain exceptions, Section 203 prohibits a
publicly-held Delaware corporation from engaging in a "business combination"
with an "interested stockholder" for a period of three years from the date of
the transaction in which the person became an interested stockholder, unless the
interested stockholder attained such status with the approval of the board of
directors or unless the business combination is approved in a prescribed manner.
A "business combination" includes mergers, asset sales and other transactions
resulting in a financial benefit to the interested stockholder. Subject to
certain exceptions, an "interested stockholder" is a person who, together with
affiliates and associates, owns, or within three years did own, fifteen percent
(15%) or more of the corporation's voting stock. This statute could prohibit or
delay the accomplishment of mergers or other takeover or change in control in
attempts with respect to us and, accordingly, may discourage attempts to acquire
us.

REGISTRATION RIGHTS

    Under the Amended and Restated Investor Rights Agreement dated as of May 10,
1999, among NetZero and certain holders of its securities, the holders of
approximately 85,698,000 shares of common stock, or Registrable Securities,
after this offering will be entitled to certain rights with respect to the
registration of the Registrable Securities under the Securities Act. Under the
Investors Rights Agreement, if NetZero proposes to register any of its
securities under the Securities Act, either for its own account or the account
of other stockholders, the holders of Registrable Securities are entitled to
notice of such registration and are entitled to include their Registrable
Securities in the registration. Of the approximately 85,698,000 shares of
Registrable Securities, approximately 21,286,000 shares are only entitled to
these "piggy back" registration rights.

    In addition, if at any time after August 15, 2000, NetZero receives a
request from certain holders of at least 20% of the Registrable Securities,
NetZero is obligated to cause these shares to be registered under the Securities
Act, provided that the offering size would exceed $5,000,000. Certain holders of
Registrable Securities have the right to cause two demand registrations.
Further, holders of Registrable Securities may require NetZero to register all
or a portion of their Registrable

                                       66
<PAGE>
Securities on Form S-2 or Form S-3 under the Securities Act, provided that the
offering size would exceed $1,000,000, when these forms become available for use
by NetZero, and subject to certain other conditions and limitations. The
holders' rights with respect to all these registrations are subject to certain
conditions, including the right of the underwriters of any of these offerings to
limit the number of shares included in any of these registrations. NetZero has
agreed to pay all expenses related to certain of these registrations, except for
underwriting discounts and commissions, to effect the registration and sale of
the Registrable Securities. Upon registration, such shares are freely tradeable
in the public market without restriction.

TRANSFER AGENT AND REGISTRAR

    The Transfer Agent and Registrar for our common stock will be U.S. Stock
Transfer Corporation.

LISTING

    Application has been made for listing the common stock on The Nasdaq

other limitations of Rule 144.

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

(1) If the underwriters waive the 180-day lock-up agreements within the first 90
    days after the date of this prospectus, an additional              shares
    will be available for sale in the public market 90 days following the date
    of this prospectus, subject in some cases to compliance with the volume and
    other limitations of Rule 144.

    In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned shares for at least one
year is entitled to sell within any three-month period commencing 90 days after
the date of this prospectus a number of shares that does not exceed the greater
of (a) 1% of the then outstanding shares of common stock (approximately
shares immediately after the offering) or (b) the average weekly trading volume
during the four calendar weeks preceding such sale, subject to the filing of a
Form 144 with respect to such sale. A person (or persons whose shares are
aggregated) who is not deemed to have been an affiliate of NetZero at any time
during the 90 days immediately preceding the sale and who has beneficially owned
his or her shares for at least two years is entitled to sell such shares
pursuant to Rule 144(k) without regard to the limitations described above.
Persons deemed to be affiliates must always sell pursuant to Rule 144, even
after the applicable holding periods have been satisfied.

    We are unable to estimate the number of shares that will be sold under Rule
144, since this will depend on the market price for our common stock, the
personal circumstances of the sellers and other factors. Prior to the offering,
there has been no public market for the common stock, and there can be no
assurance that a significant public market for the common stock will develop or
be

                                       68
<PAGE>
sustained after the offering. Any future sale of substantial amounts of the
common stock in the open market may adversely affect the market price of the
common stock offered hereby.

    Our directors, executive officers, stockholders with registration rights and
certain other stockholder and optionholders have agreed pursuant to the
underwriting agreement and other agreements that they will not sell any common
stock without the prior written consent of Goldman, Sachs & Co. for a period of
180 days from the date of this prospectus. We have also agreed not to issue any
shares during the lock-up period without the consent of Goldman, Sachs & Co.,
except that we may, without such consent, grant options and sell shares pursuant
to our stock incentive and purchase plans.

    Any of our employees or consultants who purchased his or her shares pursuant
to a written compensatory plan or contract is entitled to rely on the resale
provisions of Rule 701, which permits nonaffiliates to sell their Rule 701
shares without having to comply with the public information, holding period,
volume limitation or notice provisions of Rule 144 and permits affiliates to
sell their Rule 701 shares without having to comply with the Rule 144 holding
period restrictions, in each case commencing 90 days after the date of this
prospectus. As of              , the holders of options to purchase
approximately              shares of common stock will be eligible to sell their
shares upon the expiration of the lock-up period, subject in certain cases to
vesting of such options.

    We intend to file a registration statement on Form S-8 under the Securities
Act within       days after the completion of the offering to register
shares of common stock subject to outstanding stock options reserved for
issuance under our 1999 Stock Incentive Plan, thus permitting the resale of such
shares by nonaffiliates in the public market without restriction under the
Securities Act.

    In addition, certain stockholders have registration rights with respect to
85,698,444 shares of common stock and common stock equivalents. Registration of
the registrable securities under the Securities Act would result in such shares
becoming freely tradeable without restriction under the Securities Act.

                                 LEGAL MATTERS

    The validity of the common stock offered hereby will be passed upon for us
by Brobeck, Phleger & Harrison LLP, Irvine, California. As of June 30, 1999,
Brobeck, Phleger & Harrison LLP and certain entities and individuals affiliated
with Brobeck, Phleger & Harrison LLP beneficially owned an aggregate of 46,540
shares of our Series C preferred stock and an aggregate of 40,761 shares of our
Series D preferred stock, all of which will convert to common stock in the
offering. Certain legal matters relating to the sale of common stock in this
offering will be passed upon for the underwriters by Wilson, Sonsini, Goodrich &
Rosati, Professional Corporation, Palo Alto, California.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Stockholders
NetZero, Inc.

    In our opinion, the accompanying balance sheet and the related statements of
operations, stockholders' equity (deficit) and cash flows present fairly, in all
material respects, the financial position of NetZero, Inc. (the "Company") as of
June 30, 1998 and the results of its operations and its cash flows for the
period from July 21, 1997 (Inception) through June 30, 1998 in conformity with
generally accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these statements in accordance with generally accepted auditing standards
which require that we plan and perform the audit to obtain reasonable assurance
about whether the financial statements are free of material misstatement. An
audit includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for the opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS

         (ALL INFORMATION WITH RESPECT TO MARCH 31, 1999 IS UNAUDITED)

1.  BUSINESS:

    NetZero, Inc. ("NetZero" or the "Company") was incorporated in July 1997 and
launched its service in October 1998. NetZero provides consumers with free
access to the Internet while offering online advertisers a highly effective way
to reach those consumers. The Company offers its users free and unlimited
Internet access as well as free e-mail and navigational tools to enhance the
users online experience. For advertisers, the Company offers an online direct
marketing tool with features and functionality that have distinct advantages
over traditional forms of online advertising.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

UNAUDITED INTERIM FINANCIAL INFORMATION

    The interim financial statements of the Company as of March 31, 1999 and for
the periods from July 21, 1997 (inception) through March 31, 1998 and for the
nine months ended March 31, 1999, are unaudited. The unaudited interim financial
statements have been prepared on the same basis as the annual financial
statements and, in the opinion of management, reflect all adjustments,
consisting only of normal recurring adjustments, necessary to present fairly the
financial position, results of operations and cash flows at March 31, 1999 and
for the period from July 21, 1997 (Inception) through March 31, 1998 and for the
nine months ended March 31, 1999, respectively.

USE OF ESTIMATES

    The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent liabilities and the reported amounts of revenues and
expenses. Actual results could differ from those estimates.

CASH EQUIVALENTS

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

CONCENTRATION OF RISK

    Financial instruments that potentially subject the Company to a
concentration of credit risk consist of cash and cash equivalents and accounts
receivable. Cash and cash equivalents are deposited with major financial
institutions; at times, such balances with any one financial institution may be
in excess of FDIC insurance limits. The Company's accounts receivable are
derived primarily from revenue earned from customers located in the United
States. The Company extends credit based upon an evaluation of the customer's
financial condition and generally collateral is not required. The Company
maintains an allowance for doubtful accounts based upon the expected
collectibility of accounts receivable; to date such losses, if any, have been
within management's expectations.

    Two customers comprised 34% and 11% of the accounts receivable balance at
March 31, 1999, and for the nine months ended March 31, 1999, two customers
comprised 20% and 24% of revenues.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

         (ALL INFORMATION WITH RESPECT TO MARCH 31, 1999 IS UNAUDITED)

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
SOURCES OF SUPPLIES

    The Company relies on third-party networks, local telephone companies and
other companies to provide data communications capacity. Although management
believes that alternate telecommunications facilities could be found in a timely
manner, any disruption of these services could have an adverse effect on the
Company's financial position and results of operations.

FAIR VALUE OF FINANCIAL INSTRUMENTS

    The Company's financial instruments, including cash and cash equivalents,
accounts receivable, accounts payable, and lease obligations are carried at
historical cost, which approximates their fair value because of the short-term
maturity of these instruments and the relatively stable interest rate
environment.

PROPERTY AND EQUIPMENT

    Property and equipment are stated at historical cost. Depreciation and
amortization is computed using the straight-line method over the estimated
useful lives of the assets, generally three to five years, or the shorter of the
lease term or the estimated useful lives of the assets, if applicable.

LONG-LIVED ASSETS

    The Company identifies and records impairment losses on long-lived assets
when events and circumstances indicate that such assets might be impaired. In
the event the expected undiscounted future cash flows attributable to the asset
is less than the carrying amount of the asset, an impairment loss equal to the
excess of the asset's carrying value over its fair value is recorded. To date,
no such impairment has been recorded.

REVENUE RECOGNITION

    The Company's revenues are derived principally from the sale of banner
advertisements, sponsorships, referrals of our users to other web-sites,
performance based agreements, and distribution arrangements. To date most of the
Company's revenues have been generated from banner advertisements. Advertising
rates are dependent on whether the advertisement impressions are displayed on
the Company's banner window on a general rotation or targeted to specific
audiences. The Company's obligations typically include the guarantee of a
minimum number of impressions or the satisfaction of other performance criteria.
Advertising revenue is recognized as the impressions are displayed or as
click-throughs occur, depending on the contract terms, provided that no
significant company obligations remain and collection of the related receivable
is probable. To date, the duration of the Company's advertising commitments have
generally averaged from one to two months. To the extent minimum guaranteed
impressions or other performance criteria are not met, the Company defers
recognition of the corresponding revenues until the remaining guaranteed
impressions or other performance criteria are met.

         (ALL INFORMATION WITH RESPECT TO MARCH 31, 1999 IS UNAUDITED)

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
PRODUCT DEVELOPMENT COSTS

    Product development costs incurred by the Company to develop, enhance,
manage, monitor and operate the Company's Web-sites and related technologies are
expensed as incurred.

ADVERTISING EXPENSE

    Advertising costs are expensed as incurred and totalled $0 and $78,000 for
the period from July 21, 1997 (Inception) through June 30, 1998 and for the nine
months ended March 31, 1999, respectively.

STOCK-BASED COMPENSATION

    The Company accounts for stock-based employee compensation arrangements in
accordance with the provisions of Accounting Principles Board Opinion ("APB")
No. 25, "Accounting for Stock Issued to Employees," and complies with the
disclosure provisions of Statement of Financial Accounting Standards ("SFAS")
No. 123, "Accounting for Stock-Based Compensation." Under APB 25, compensation
expense is recognized over the vesting period based on the difference, if any,
on the date of grant between the deemed fair value of the Company's stock for
accounting purposes and the exercise price. The Company accounts for stock
issued to non-employees in accordance with the provisions of SFAS No. 123 and
Emerging Issues Task Force 96-18.

INCOME TAXES

    The Company utilizes the liability method of accounting for income taxes.
Under this method, deferred tax liabilities and assets are determined based on
the difference between the financial statement and the tax bases of assets and
liabilities using enacted tax rates in effect for the period in which the
differences are expected to reverse. Valuation allowances are established, when
necessary, to reduce deferred tax assets to the amount expected to be realized.

NET LOSS PER SHARE

    Basic and diluted net loss per share is computed by dividing the net loss
for the period by the weighted average number of common shares outstanding
during the period. Shares associated with stock options, warrants and
convertible preferred stock are not included to the extent they are
antidilutive.

UNAUDITED PRO FORMA NET LOSS PER SHARE

    Unaudited pro forma net loss per share is computed by dividing the net loss
for the period by the weighted average number of common shares outstanding,
including the pro forma effects of the automatic conversion of the Company's
convertible preferred stock into shares of the Company's common stock effective
upon the closing of the Company's initial public offering as if such conversion
occurred on July 1, 1998 or at the date of original issuance, if later. The
resulting pro forma adjustment includes an increase in weighted average shares
used to compute basic and diluted net loss per share of 14,501,000 for the nine
months ended March 31, 1999.

         (ALL INFORMATION WITH RESPECT TO MARCH 31, 1999 IS UNAUDITED)

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
COMPREHENSIVE INCOME

    Effective July 1, 1998, the Company adopted the provisions of SFAS No. 130,
"Reporting Comprehensive Income." SFAS No. 130 establishes standards for
reporting comprehensive income and its components in financial statements.
Comprehensive income, as defined, includes all changes in equity (net assets)
during a period from non-owner sources. To date, the Company has not had any
transactions that are required to be reported in comprehensive income.

SEGMENTS

    Effective July 1, 1998, the Company adopted the provisions of SFAS No. 131,
"Disclosures about Segments of an Enterprise and Related Information." SFAS No.
131 establishes standards for the way companies report information about
operating segments in annual financial statements. It also establishes standards
for related disclosures about products and services, geographic areas and major
customers. The Company has determined that it does not have any separately
reportable business segments as of June 30, 1998 and March 31, 1999.

RECENT ACCOUNTING PRONOUNCEMENTS

    In March 1998, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position ("SOP") No. 98-1, "Software for Internal
Use," which provides guidance on accounting for the cost of computer software
developed or obtained for internal use. The Company expects that the adoption of
SOP 98-1 will not have a material impact on its financial position, results of
operations or cash flows. The Company will be required to implement SOP No. 98-1
in the first quarter of fiscal 2000.

    In April 1998, the AICPA issued SOP No. 98-5, "Reporting on the Costs of
Start-Up Activities." SOP No. 98-5 requires that all start-up costs related to
new operations must be expensed as incurred. In addition, start-up costs that
were capitalized in the past must be written off when SOP No. 98-5 is adopted.
The Company expects that the adoption of SOP No. 98-5 will not have a material
impact on its financial position, results of operations or cash flows. The
Company will be required to implement SOP No. 98-1 in the first quarter of
fiscal 2000.

    In June 1998, The Financial Accounting Standards Board issued SFAS No. 133
"Accounting for Derivative Instruments and Hedging Activities." The statement
requires the recognition of all derivatives as either assets or liabilities in
the balance sheet and the measurement of those instruments at fair value. The
accounting for changes in the fair value of a derivative depends on the planned
use of the derivative and the resulting designation. Because the Company does
not currently hold any derivative instruments and does not engage in hedging
activities, the impact of the adoption of SFAS No. 133 is not currently expected
to have a material impact on financial position, results of operations or cash
flows. The Company will be required to implement SFAS No. 133 in the first
quarter of fiscal 2001.

5.  RELATED-PARTY TRANSACTIONS:

    In September 1998, the Company purchased certain software technology for
$80,000 in cash from a related party.

    At March 31, 1999, the Company held a note receivable from an employee for
$629,000 for the exercise of stock options. The note bears interest at 4.83% per
annum and is due on March 20, 2004 unless paid earlier. The note, which is
classified as a component of stockholders' equity, has recourse provisions and
is collateralized by the shares of common stock issued upon exercise.

6.  STOCK OPTIONS:

    The Company's 1998 and 1999 Stock Option and Stock Issuance Plans (the
"Plans") provide for the issuance of stock and stock options at prices not less
than 85% (110% if the award is issued to a 10% stockholder) of the fair market
value at the date of issue. An aggregate of 15,000,000 shares were reserved
under the Plans, of which 1,541,000 shares were available for future grant at
March 31, 1999 and 3,455,000 options were outstanding at March 31, 1999.

         (ALL INFORMATION WITH RESPECT TO MARCH 31, 1999 IS UNAUDITED)

6.  STOCK OPTIONS: (CONTINUED)
    The Plans provide for the grant of nonstatutory and incentive stock options
to employees, officers, directors and consultants of the Company. Options
granted are generally immediately exercisable for unvested shares of common
stock, with the unvested portion of the shares remaining subject to repurchase
by the Company at the exercise price until the vesting period is complete. The
Company had 8,407,000 unvested shares of common stock outstanding at March 31,
1999 (Note 7).

    The Stock Issuance Equity Program provides for the issuance of common stock
directly to participants and may vest immediately or in one or more installments
over the service period but at not less than 20% per year vesting. Unvested
shares of common stock remain subject to repurchase by the Company at the
original issuance price. There were no shares issued under the Stock Issuance
program as of March 31, 1999.

    The following table summarizes activity under the Plan for the period from
July 21, 1997 (Inception) through June 30, 1998 and for the nine months ended

    The outstanding Series A and Series B redeemable convertible preferred
shares ("Series A" and "Series B") above exclude 704,000 and 422,000 shares,
respectively, which the Company is obligated to issue at $.0889 and $.1481 per
share, respectively, as part of the Series A and Series B financing in 1998.
These shares were issued on June 30, 1999 in exchange for cash.

    VOTING.  Each share of preferred stock has a number of votes equal to the
number of shares of common stock then issuable upon its conversion. The
preferred stock generally votes together with the common stock and not as a
separate class.

    DIVIDENDS.  The holders of each series of preferred stock are entitled to
receive noncumulative dividends when, as and if declared by the Board of
Directors at a rate of 8% of the respective issuance price per share per annum.
No dividends have been declared or paid from inception.

    LIQUIDATION.  In the event of any liquidation or winding up of the Company,
the holders of each series of preferred stock will be entitled to receive, in
preference to the holders of common stock, any distribution of assets of the
Company equal to the sum of the respective issuance price of such shares plus
any accrued and unpaid dividends.

    After the full liquidation preference on all outstanding shares of preferred
stock has been paid, any remaining funds and assets of the Company will be
distributed pro rata among the holders of the preferred stock and common stock,
assuming conversion of each series of the preferred shares until the holders of
the Series A, Series B and Series C shares have received an aggregate of five

times the then-existing conversion price which would result in maximum per share
distribution amounts of $0.44, $0.74 and $2.15, respectively. The conversion
price is considered the original issuance price adjusted for certain dilutive
issuances, stock splits and combinations, if any.

    REDEMPTION.  If a liquidation or initial public offering has not occurred by
September 9, 2003, the holders of Series A and B redeemable convertible
preferred stock are entitled to a redemption out of the assets of the Company
equal to the issue price per share and any declared but unpaid dividends at the
date of redemption.

    CONVERSION.  Each share of preferred stock is convertible at the holder's
option at any time into common stock, according to a ratio which is one-for-one,
subject to adjustment for dilution. Each share of preferred stock automatically
converts into common stock at the then applicable conversion rate upon (i) the
closing of an underwritten public offering pursuant to which the post-closing
enterprise value is at least $50,000,000 and the Company receives proceeds of
not less than $10,000,000, or (ii) the consent of a majority of the then
outstanding preferred stockholders. As of March 31, 1999, the Company was
required to keep available, out of its authorized but unissued shares of common
stock, 45,206,000 shares for conversion of preferred stock.

COMMON STOCK

    As a condition to the issuance of Series A redeemable convertible preferred
stock in September 1998, the employee founding stockholders of all of the then
15 million outstanding common shares entered into stock restriction agreements
with the Company pursuant to which 7.5 million of the outstanding common shares
were restricted and were made subject to monthly vesting over a four-year period
based on the founders continued employment with the Company. Under the terms of
the restricted stock agreements, the Company has the right to repurchase the
unvested shares at the original issue price in the event a founder ceases to be
an employee or service provider to the Company. The repurchase right shall
automatically lapse with respect to the unvested shares in the event the founder
is terminated without cause following a corporate transaction, defined as a (i)
merger or consolidation with more than a 50% change of control or (ii) sale,
transfer or disposition of substantially all the Company's assets in a
dissolution. The Company recorded deferred stock compensation amounting to
$333,000 for the shares covered under the restricted stock agreements. The
deferred amount will be recognized as compensation expense over the vesting
period. During the nine months ended March 31, 1999, such compensation expense
included in stock-based charges in the statement of operations amounted to
$130,000.

    At March 31, 1999, 14,970,000 shares of common stock were subject to
repurchase, of which 6,563,000 shares related to unvested shares under the
restricted stock agreements and 8,407,000 shares related to unvested stock
options exercised.

WARRANTS

    Under the terms of a loan outstanding during the third quarter of 1999, the
Company issued fully vested and exercisable warrants to purchase 23,000 shares
of its Series C convertible

    The diluted per share computations exclude convertible preferred stock and
options which were antidilutive. The number of shares excluded from the diluted
net loss per share computation were 4,316,000 and 63,132,000 for the period from
July 21, 1997 (Inception) through June 30, 1998 and for the nine months ended
March 31, 1999, respectively. The number of such shares excluded from the pro

ended March 31, 1999.

9.  EMPLOYEE BENEFIT PLAN:

    The Company has a 401(k) Profit Sharing Plan ("the Plan") available to all
employees who meet the Plan's eligibility requirements. Under the Plan,
participating employees may defer a percentage (not to exceed 15%) of their
eligible pretax earnings up to the Internal Revenue Service's annual
contribution limit. Company matching and profit sharing contributions are
discretionary. To date, the Company has not made any contributions to the Plan
as of March 31, 1999.

</TABLE>

    Due to the uncertainty surrounding the realization of the benefits in future
tax returns, the Company has placed a valuation allowance against its deferred
tax assets.

    At June 30, 1998, the Company had net operating losses for federal and state
income tax purposes of approximately $25,000 which begin to expire in 2018 for
federal income tax purposes. The net operating losses can be carried forward to
offset future taxable income. Utilization of the above carryforwards may be
subject to utilization limitations, which may inhibit the Company's ability to
use carryforwards in the future.

OPERATING LEASE

    The Company leases its facilities under a noncancelable operating lease
expiring in 2009. The lease contains a provision that payments may be adjusted
for increases in the lessor's direct costs as well as a five-year renewal
option. The Company must maintain a letter of credit with a financial
institution as a security deposit in accordance with the facility lease
agreement. The letter of credit, which remains in effect until March 2000, is
collateralized by a certificate of deposit account which is classified as
restricted cash at March 31, 1999.

12.  SUBSEQUENT EVENTS:

SALE OF SERIES D CONVERTIBLE PREFERRED STOCK

    In May 1999, the Company issued 18,082,000 shares of Series D convertible
preferred stock ("Series D Preferred") for $33,271,000. All holders of Series D
preferred have voting, dividend and liquidation preferences substantially the
same as holders of Series A, B and C convertible preferred stock. There are no
redemption rights associated with the series D preferred stock offering.

INITIAL PUBLIC OFFERING AND UNAUDITED PRO FORMA STOCKHOLDERS' EQUITY:

    In July 1999, the Board of Directors authorized the filing of a registration
statement with the Securities and Exchange Commission ("SEC") that would permit
the Company to sell shares of the Company's common stock in connection with a
proposed initial public offering ("IPO"). If the IPO is consummated under the
terms presently anticipated, upon the closing of the proposed IPO, all of the
then outstanding shares of the Company's convertible preferred stock and
redeemable convertible preferred stock will automatically convert into shares of
common stock on a one-for-one basis, subject to antidilution provisions.

    In July 1999, the Board of Directors approved the reincorporation of the
Company in the State of Delaware, the change in the par value of the Company's
common stock and the increase in the number of authorized shares which will be
effected prior to the closing of the IPO.

STOCK SPLIT

    In July 1999, the Company authorized and implemented a three-for-two forward
stock split. The share information in the accompanying financial statements has
been retroactively restated to reflect the effect of the stock split.

    If the underwriters sell more shares than the total number set forth in the
table above, the underwriters have an option to buy up to an additional
      shares from NetZero to cover such sales. They may exercise that option for
30 days. If any shares are purchased pursuant to this option, the underwriters
will severally purchase shares in approximately the same proportion as set forth
in the table above.

    The following table shows the per share and total underwriting discounts and
commissions to be paid to the underwriters by NetZero. Such amounts are shown
assuming both no exercise and full exercise of the underwriters' option to
purchase       additional shares.

    Shares sold by the underwriters to the public will initially be offered at
the initial public offering price set forth on the cover of this prospectus. Any
shares sold by the underwriters to securities dealers may be sold at a discount
of up to $      per share from the initial public offering price. Any such
securities dealers may resell any shares purchased from the underwriters to
certain other brokers or dealers at a discount of up to $      per share from
the initial public offering price. If all the shares are not sold at the initial
offering price, the representatives may change the offering price and the other
selling terms.

    NetZero has agreed with the underwriters not to dispose of or hedge any of
its common stock or securities convertible into or exchangeable for shares of
common stock during the period from the date of this Prospectus continuing
through the date 180 days after the date of this prospectus, except with the
prior written consent of Goldman, Sachs & Co. This agreement does not apply to
any existing employee benefit plans. See "Shares Eligible for Future Sale" for a
discussion of certain transfer restrictions.

    At the request of NetZero, the underwriters have reserved for sale, at the
initial public offering price, up to       % of the common stock offered hereby
for sale to certain directors, employees and associates of NetZero. There can be
no assurance that any of the reserved shares will be purchased. The number of
shares available for sale to the general public in this offering will be

                                      U-1
<PAGE>
reduced by the number of reserved shares sold. Any reserved shares not so
purchased will be offered to the general public on the same basis as the other
shares offered hereby.

    Prior to the offering, there has been no public market for the shares. The
initial public offering price will be negotiated among NetZero and the
representatives. Among the factors to be considered in determining the initial
public offering price of the shares, in addition to prevailing market
conditions, will be NetZero's historical performance, estimates of the business
potential and earnings prospects of NetZero, an assessment of NetZero's
management and the consideration of the above factors in relation to market
valuation of companies in related businesses.

    Application has been made for quotation of the Common Stock on The Nasdaq
National Market under the symbol "NZRO".

    In connection with the offering, the underwriters may purchase and sell
shares of common stock in the open market. These transactions may include short
sales, stabilizing transactions and purchases to cover positions created by
short sales. Short sales involve the sale by the underwriters of a greater
number of shares than they are required to purchase in the offering. Stabilizing
transactions consist of certain bids or purchases made for the purpose of
preventing or retarding a decline in the market price of the common stock while
the offerings are in progress.

    The underwriters also may impose a penalty bid. This occurs when a
particular underwriter repays to the underwriters a portion of the underwriting
discount received by it because the representatives have repurchased shares sold
by or for the account of such underwriter in stabilizing or short covering
transactions.

    These activities by the underwriters may stabilize, maintain or otherwise
affect the market price of the common stock. As a result, the price of the
common stock may be higher than the price that otherwise might exist in the open
market. If these activities are commenced, they may be discontinued by the
underwriters at any time. These transactions may be effected on The Nasdaq
National Market, in the over-the-counter market or otherwise.

    The underwriters do not expect sales to discretionary accounts to exceed
five percent of the total number of shares offered.

    NetZero estimates that the total expenses of the offering, excluding
underwriting discounts and commissions, will be approximately $      . NetZero
will pay all such expenses.

    NetZero has agreed to indemnify the several underwriters against certain
liabilities, including liabilities under the Securities Act of 1933.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    The Company's Certificate of Incorporation (the "Certificate") provides
that, except to the extent prohibited by the Delaware General Corporation Law
(the "DGCL"), the Company's directors shall not be personally liable to the
Company or its stockholders for monetary damages for any breach of fiduciary
duty as directors of the Company. Under the DGCL, the directors have a fiduciary
duty to the Company which is not eliminated by this provision of the Certificate
and, in appropriate circumstances, equitable remedies such as injunctive or
other forms of nonmonetary relief will remain available. In addition, each
director will continue to be subject to liability under the DGCL for breach of
the director's duty of loyalty to the Company, for acts or omissions which are
found by a court of competent jurisdiction to be not in good faith or involving
intentional misconduct, for knowing violations of law, for actions leading to
improper personal benefit to the director, and for payment of dividends or
approval of stock repurchases or redemptions that are prohibited by DGCL. This
provision also does not affect the directors' responsibilities under any other
laws, such as the federal securities laws or state or federal environmental
laws. The Company has obtained or will obtain liability insurance for its
officers and directors.

    Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers, provided that this provision
shall not eliminate or limit the liability of a director: (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) arising under Section 174 of the DGCL, or (iv)
for any transaction from which the director derived an improper personal
benefit. The DGCL provides further that the indemnification permitted thereunder
shall not be deemed exclusive of any other rights to which the directors and
officers may be entitled under the corporation's bylaws, any agreement, a vote
of stockholders or otherwise. The Certificate eliminates the personal liability
of directors to the fullest extent permitted by Section 102(b)(7) of the DGCL
and provides that the Company shall fully indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed

                                      II-1
<PAGE>
action, suit or proceeding (whether civil, criminal, administrative or
investigative) by reason of the
fact that such person is or was a director or officer of the Company, or is or
was serving at the request of the Company as a director or officer of another
corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise, against expenses (including attorney's fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by such person in
connection with such action, suit or proceeding.

    The Company, with the approval of the Board of Directors, intends to obtain
directors' and officers' liability insurance prior to the effectiveness of this
offering. In addition, the Company intends to enter into indemnification
agreements with each of its directors, a form of which is filed as Exhibit 10.27
hereto.

    There is no pending litigation or proceeding involving any director,
officer, employee or agent of the Company in which indemnification will be
required or permitted. Moreover, the Company is not aware of any threatened
litigation or proceeding that might result in a claim for such indemnification.
The Company believes that the foregoing indemnification provisions and
agreements are necessary to attract and retain qualified persons as directors
and executive officers.

    The Underwriting Agreement (the form of which is filed as Exhibit 1.1
hereto) provides for indemnification by the underwriters of NetZero and its
officers and directors, and by NetZero of the underwriters, for certain
liabilities arising under the Securities Act or otherwise.

ITEM 15. RECENT SALES OF UNREGISTERED SECURITIES.

    The following is a summary of transactions by the Company since the
Company's inception in July 1997 involving sales of the Company's securities

<PAGE>

aggregate of 17,128,182 shares of common stock to our directors, executive
officers, employees and consultants at a weighted exercise price of $0.218. As
of June 30, 1999, options to purchase 5,673,699 shares at an exercise price of
$0.033 per share, options to purchase 8,132,208 shares at an exercise price of
$0.10 per share, options to purchase 1,200,000 shares at an exercise price of
$.0333 and options to purchase 1,919,925 shares at an exercise price of $0.867,
and options to purchase 202,350 shares at an exercise price of $3.333 had been
issued.

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

ITEM 17. UNDERTAKINGS.

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

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, or otherwise, the Company 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 and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Company of expenses
incurred or paid by a director, officer or controlling person of the Company in
the successful defense of any action, suit, or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the Company 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 and will be governed by the final
adjudication of such issue.

    The undersigned Company hereby undertakes that:

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

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

"Assignment."

                  1.2 Each Assignor hereby represents, warrants and agrees that
immediately following the Initial Series A Closing such Assignor will not have,
and to the best knowledge of each such Assignor, no other Assignor will have,
any right, title or interest in or to the Technology or the Proprietary Rights
or any salary or other compensation or payment of any kind whatsoever from the
Company.


<PAGE>

                  1.3 Each Assignor hereby further represents, warrants and
agrees that (i) to the extent such Assignor has any rights, title, claim or
interest in or to any of the Technology or Proprietary Rights on or prior to the
date hereof, such Assignor has not assigned, transferred, licensed, pledged or
otherwise encumbered any Technology or Proprietary Right or agreed to do so,

                  1.4 Each Assignor agrees to assist the Company in every proper
way to evidence and perfect the Assignment and to apply for and obtain and from
time to time enforce, maintain, and defend the Proprietary Rights in any and all
countries the Company may designate from time to time. Each Assignor will
execute all documents the Company may request for such purposes.

                  1.5 In the event that the Company is unable for any reason
whatsoever to secure Assignor's signature to any document Assignor is required
to execute pursuant to the foregoing, Assignor hereby irrevocably designates and
appoints the Company and its duly authorized officers and agents, as his agents
and attorneys-in-fact to act for and on his behalf and instead of Assignor, to
execute and file any such document and to do all other lawfully permitted acts
to further the purposes of the foregoing with the same legal force and effect as
if executed by the Assignor.

         2.       REPAYMENT OF INDEBTEDNESS. Impact hereby acknowledges and
agrees that upon delivery of the funds to Impact as contemplated by Section 4 of
this Agreement, all of the Company's indebtedness to Impact as of the date

executors, administrators, assigns and successors, fully and forever releases
and discharges the Company and each of its currently, former and future parents,
subsidiaries, related entities, predecessors, successors, officers, directors,
shareholders, agents, employees and assigns (collectively, "Releasees") with
respect to any and all claims, liabilities and causes of action, of every
nature, kind and description, in law, equity or otherwise, which have arisen,
occurred or existed at any time prior to the signing of this Agreement,
including, without limitation, any and all claims, liabilities and causes of
action arising out of or relating to the Technology and the Proprietary Rights.
Each Assignor understands and agrees that he/she/it is waiving any rights
he/she/it may have had, now has, or in the future may have to pursue any and all
remedies available to him/her/it under any cause of action. In addition, and in
further consideration of the foregoing, each Assignor expressly waives any and
all rights and benefits conferred upon him/her/it by the provisions of Section
1542 of the Civil Code of the State of California, which states as follows:

                  A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR
                  DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF
                  EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM, MUST HAVE
                  MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.

                           STOCK RESTRICTION AGREEMENT

              THIS AGREEMENT is made this 11th day of September, 1998, by and
between NetZero, Inc., a California corporation (the "Company") and ________
("Shareholder"). Capitalized terms used but not otherwise defined in this
Stock Restriction Agreement shall have the meaning given such terms in the
Stock Purchase Agreement (as defined below).

              WHEREAS, the Shareholder is the owner of ________ shares of
the Company's Common Stock (the "Shares");

              WHEREAS, as an inducement to and in consideration of the
consummation by certain investors of the transactions contemplated by that
certain Preferred Stock Purchase Agreement dated on or about the date hereof
(the "Stock Purchase Agreement"), Shareholder has agreed to subject fifty
percent (50%) of the Shares (the "Unvested Stock") to a repurchase right at
cost in favor of the Company on the terms set forth below.

              NOW THEREFORE, IT IS HEREBY AGREED:

              1.  TRANSFER RESTRICTIONS.

                 (a) RESTRICTION ON TRANSFER. Shareholder shall not transfer,
assign, encumber or otherwise dispose of any of the Unvested Stock which are
subject to the Company's Repurchase Right under Section 2. Such restrictions
on transfer, however, shall not be applicable to (i) a gratuitous transfer of
Unvested Stock made to the Shareholder's spouse or issue, including adopted
children, or to a trust for the exclusive benefit of the Shareholder or the
Shareholder's spouse or issue, or (ii) a transfer of title to the Unvested
Stock effected pursuant to the Shareholder's will or the laws of intestate
succession.

                 (b) TRANSFEREE OBLIGATIONS. Each person to whom shares of
the Unvested Stock are transferred by means of one of the permitted transfers
specified in Section 1(a) must, as a condition precedent to the validity of
such transfer, acknowledge in writing to the Company that such person is
bound by the provisions of this Agreement and that the transferred shares are
subject to the Company's Repurchase Right granted hereunder, to the same
extent such shares would be so subject if retained by the Shareholder.

                 (c) DEFINITION OF OWNER. For purposes of Section 2 of this
Agreement, the term "Owner" shall include the Shareholder and all subsequent
holders of the Unvested Stock who derive their chain of ownership through a
permitted transfer from the Shareholder in accordance with Section 1(a).

              2. REPURCHASE RIGHT.

                 (a) GRANT. The Company is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the sixty (60) day period
following the date the Shareholder ceases for any reason to be a Service
Provider (as defined herein) to the Company, to repurchase, at a price per
share of $.0002 per share (the "Repurchase Price"), up to all or a

<PAGE>

portion of the Unvested Stock as set forth in Section 2(c). For purposes of
this Agreement, the Shareholder shall be deemed to be a "Service Provider" to
the Company so long as he renders services to the Company or one or more of
its parent or subsidiary corporations, whether as an employee or an
independent non-employee consultant.

                 (b) EXERCISE OF THE REPURCHASE RIGHT. The Repurchase Right
shall be exercisable by written notice delivered to the Owner of the shares
to be repurchased prior to the expiration of the applicable sixty (60) day
period specified in Section 2(a). The notice shall indicate the number of
shares of Unvested Stock to be repurchased and the date on which the
repurchase is to be effected, such date to be not more than thirty (30) days
after the date of notice. If the shares to be repurchased are held in escrow,
the Company may effect the repurchase by delivering to the Owner cash or cash
equivalents in an amount equal to the Repurchase Price multiplied by the
number of shares of Unvested Stock which are to be repurchased either (i)
concurrently with the notice referenced above or (ii) on the date specified
in the notice, and, upon delivery of such payment, the repurchase of such
Unvested Stock shall be deemed completed. If the Owner is in possession of
the certificate evidencing the shares to be repurchased, the Owner shall,
prior to the close of business on the date specified for the repurchase,
deliver to the Secretary of the Company the certificates representing the
Unvested Stock to be repurchased, each certificate to be properly endorsed
for transfer. The Company shall, promptly following receipt of such stock
certificates, pay to the Owner an amount equal to the Repurchase Price to be
paid for the shares which are to be repurchased.

                 (c) TERMINATION OF THE REPURCHASE RIGHT. The Repurchase
Right shall apply to all shares of the Unvested Stock and shall lapse with
respect to, and Shareholder shall accordingly acquire a vested interest in,
the Unvested Stock in a series of forty-eight (48) successive monthly
installments upon Shareholder's completion of each additional month as a
Service Provider to the Company over the forty-eight (48) month period
measured from September 11, 1998.

                 (d) ADDITIONAL SHARES OR SUBSTITUTED SECURITIES. In the
event of any stock dividend, stock split, recapitalization or other change
affecting the company's outstanding Common Stock as a class without receipt
of consideration, then any new, substituted or additional securities or other
property (including money paid other than as a regular cash dividend), which
is by reason of any such transaction distributed to the Shareholder with
respect to the Unvested Stock, shall be immediately subject to the Repurchase
Right. Appropriate adjustments to reflect the distribution of such securities
or property shall be made to the number of shares of Unvested Stock for all
purposes relating to the Repurchase Right, and the Company (or its
successors) may require the establishment of an escrow account for any
property or money (other than regular cash dividends) distributed with
respect to the shares covered by the Repurchase Right in order to facilitate
the exercise of such right. Appropriate adjustments shall also be made to the
price per share to be paid upon the exercise of the Repurchase Right in order
to reflect the effect of any such transaction upon the Company's capital
structure; provided, however, that the aggregate purchase price shall remain
the same.

              3. LEGENDS. All certificates representing shares of stock of
the Company subject to the provisions of this Agreement shall have endorsed
thereon the following legend:

                                       2

                 "THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT
          TO THE TERMS AND CONDITIONS OF A CERTAIN STOCK RESTRICTION AGREEMENT
          WHICH INCLUDES A REPURCHASE RIGHT. COPIES OF THE AGREEMENT MAY BE
          OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF NETZERO, INC."

              4. ESCROW OF SHARES.

                 (a) ESCROW HOLDER. The Unvested Stock shall be held in
escrow by the Secretary of the Company, as escrow holder ("Escrow Holder"),
along with an Assignment Separate from Certificate executed by Shareholder in
blank in the form attached hereto as Schedule B, until expiration of the
Company's Repurchase Right.

                 (b) INSTRUCTIONS TO ESCROW HOLDER. The Escrow Holder is
hereby directed to permit the transfer or repurchase of the Unvested Stock
only in accordance with this Agreement or instructions signed by the
Shareholder and an officer of the Company other than the Shareholder. If the
Company's Repurchase Right is exercised, the Escrow Holder is hereby
authorized to take all necessary and appropriate action, including, without
limitation, the completion and delivery to the Company of Schedule A hereto,
to effect the purposes of this Agreement. In the event that further
instructions are desired by the Escrow Holder, he or she shall be entitled to
rely upon directions executed by an officer of the Company other than the
Shareholder. The Escrow Holder shall have no liability for any act or
omission hereunder while acting in good faith in the exercise of his or her
own judgment. Upon lapse of the Repurchase right, the Escrow Agent shall
deliver to the Shareholder all documents, securities or other property
belonging to Shareholder, and shall be discharged of all further obligations
hereunder.

                 (c) RIGHTS OF SHAREHOLDER. Subject to the terms hereof, the
Shareholder shall have all the rights of a shareholder with respect to
Unvested Stock while such shares are held in escrow, including without
limitation the right to vote the Unvested Stock and receive any cash
dividends declared thereon.

              5. MISCELLANEOUS.

                 (a) EFFECTIVENESS. This Stock Restriction Agreement shall be
effective only upon the closing of the transactions contemplated by the Stock
Purchase Agreement.

                 (b) FURTHER INSTRUMENTS AND ACTIONS. The parties agree to
execute such further instruments and to take such further action as may
reasonably be necessary to carry out the intent of this Agreement.

                 (c) NOTICES. Any notice required or permitted hereunder
shall be given in writing and shall be deemed effectively given upon personal
delivery or upon deposit in the United States Post Office, by registered or
certified mail with postage and fees prepaid, addressed to the other party
hereto at his or her address hereinafter shown below his or her signature or
at such other address as such party may designate by ten (10) days' advance
written notice to the other party hereto.

                                       3

<PAGE>

                 (d) GOVERNING LAW. The Agreement is governed by the internal
law of California and shall inure to the benefit of the successors and
assigns of the Company and, subject to the restriction on transfer herein set
forth, be binding upon the Shareholder, his or her heirs, executors,
administrators, guardians, successors and assigns.

                 (e) AMENDMENTS AND WAIVERS. This Agreement represents the
entire understanding of the parties with respect to the subject matter hereof
and supersedes all previous understandings, written or oral. This Agreement
may only be amended with the written consent of the parties hereto, and no
oral waiver or amendment shall be effective under any circumstances
whatsoever.

                 (f) NO WAIVER. The failure of the Company in any instance to
exercise the Repurchase Rights granted hereunder shall not constitute a
waiver of any other repurchase rights that may subsequently arise under the
provisions of this agreement or any other agreement between the Company and
Shareholder. No waiver of any breach or condition of this Agreement shall be
deemed to be a waiver of any other or subsequent breach or condition, whether
of like or different nature.

                 (g) ASSIGNMENT. The Company's Repurchase Right may only be
assigned if the company is legally or contractually prohibited from
exercising the Repurchase Right. In the event the Company does assign the
Repurchase Right, the Company shall use its best efforts to ensure that the
benefits of the Repurchase Right inure generally to the Company or are shared
ratably by all of the Company's shareholders. This provision is intended for
the benefit of the Company's shareholders generally and not for Shareholder
individually, and may be amended or waived without Shareholder's consent.

shares of the Company's Series B Preferred Stock (as defined below) set forth

         1.5 SERIES B CLOSINGS. The initial purchase and sale of the Series B
Preferred Stock (the "INITIAL SERIES B CLOSING") shall take place at the
offices of BPH at 10:00 a.m., on the eleventh (11th) business day following
the Investors' verification of the Company's satisfaction of each of the
criteria specified on SCHEDULE 1.5, or at such other earlier time and place
as the Investors acquiring in the aggregate more than half the shares of
Series B Preferred Stock sold pursuant hereto shall determine, whether or not
the criteria specified on SCHEDULE 1.5 have been satisfied, with a written
notice of the new closing date to be delivered by the Investors to the
Company not less than three (3) business days prior to such date (the
"INITIAL SERIES B CLOSING DATE"). Investors shall reasonably determine
whether such criteria have been satisfied, if at all, within two (2) business
days following receipt by the Investors of a written notice of completion
signed by the Company's Chief Financial Officer. If the Investors reasonably
determine that such criteria have not been satisfied, the matter shall be
referred to arbitration in accordance with Section 8.10 hereof and the
Initial Series B Closing shall occur, if at all, on the second (2nd) business
day following the arbitrator's finding that the criteria specified on
SCHEDULE 1.5 have been satisfied. The second purchase and sale of the Series
B Preferred Stock (the "SECOND SERIES B CLOSING") shall take place at the
offices of BPH at 10:00 a.m. on the date which is thirty (30) days after the
Initial Series B Closing Date (or, if such date is not a business day, the

third purchase and sale of Series B Preferred Stock (the "THIRD SERIES B
CLOSING") shall take place at the offices of BPH at 10:00 a.m., on the date
which is sixty (60) days after the Initial Series B Closing Date (or, if such

SERIES B CLOSING DATE"). The fourth purchase and sale of the Series B
Preferred Stock (the "FOURTH SERIES B CLOSING") shall take place at the
offices of BPH at 10:00 a.m. on the later to occur of (i) the first
anniversary of the Initial Series A Closing (or, if such date is not a
business day, the first business day thereafter) or the Third Series B
Closing Date (the "FOURTH SERIES B CLOSING DATE"). At each Series B Closing
the Company shall deliver to each purchasing Investor a certificate
representing the Series B



                                       2
<PAGE>

Preferred Stock that such Investor is purchasing against payment of the
purchase price therefor by check or wire transfer; provided, however, that
the consideration to be delivered by Idealab at the Fourth Series B Closing
shall be services as set forth in Section 1.6 below.

         1.6 IDEALAB SERVICES. From the date hereof until the first
anniversary of this Agreement, Idealab hereby agrees to render and the
Company hereby agrees to purchase and accept $125,000 of services from
Idealab. The parties hereby agree that the cancellation of the accounts
payable for past services rendered by Idealab to the Company during such
period shall constitute consideration on a dollar-for-dollar basis (e.g. for
each dollar of services rendered, a dollar of stock is earned) for the shares
of Series A Preferred Stock and Series B Preferred Stock issued by the
Company to Idealab; provided, however, that the Company shall only be
obligated to issue to Idealab $62,500 of Series A Preferred Stock at the
Fourth Series A Closing and $62,500 of Series B Preferred Stock at the Fourth
Series B Closing. The initial $62,500 of services shall be consideration for
the Series A Preferred Stock and the next $62,500 of services shall be
consideration for the Series B Preferred Stock. Idealab shall provide to the
Company a monthly invoice for such services. The services shall be billed to
the Company at a rate which is identical to the rate Idealab charges its own
portfolio companies at the time the services are rendered. Idealab shall
remit to the Company at the Fourth Series A Closing and the Fourth Series B
Closing, as the case may be, an executed instrument of cancellation in form
and substance acceptable to the Company reflecting the cancellation of the
Company's indebtedness to Idealab for the applicable services rendered.

         1.7 IDEALAB OPTION. The Company hereby grants to Idealab an option
to purchase 468,867 shares of Series A Preferred Stock (the "SERIES A
OPTION") at an exercise price of $0.1333 per share and an option to purchase
281,278 shares of Series B Preferred Stock (the "SERIES B OPTION") at an
exercise price of $0.2222 per share. Each such option shall be a
non-statutory stock option. The Series A Option shall have a maximum term of
six (6) months measured from the date of this Agreement (the "INITIAL TERM").
The Series A Option and the Series B Options shall be exercisable for all of
the option shares (or not at all) as follows: (i) if the Third Series B
Closing occurs at any time within the Initial Term, the Series A Option and
the Series B Option may be exercised at any time after the Third Series B
Closing until the expiration of the Initial Term and shall both be exercised
in full and on the same date (or not at all) during such period and (ii) if
the Third Series B Closing occurs at any time after the Initial Term, the
Series A Option shall be exercisable during the Initial Term so long as, upon
exercise, Idealab executes a written agreement obligating Idealab to exercise
the Series B Option at the Third Series B Closing. In order to exercise each
such option, Idealab shall deliver to the Company a notice of exercise and a
check for $62,500 to the Company on or before the applicable expiration date.
Each such option must be exercised in full; partial exercises are not
permitted. Within ten (10) days following exercise, Idealab shall receive a
stock certificate for that number of shares of Series A Preferred Stock or
Series B Preferred Stock, as the case may be, for which the option was
validly exercised.

         1.8 SALE AND ISSUANCE OF ADDITIONAL CAPITAL STOCK. The Company hereby
agrees that it will not issue or agree to issue any Common Stock or Preferred
Stock to any individual or entity other than the Investors until the earlier to
occur of (i) eight (8) months following the Initial Series A Closing or (ii)
satisfaction of the criteria specified on SCHEDULE 1.5 and SCHEDULE 1.8;
PROVIDED, HOWEVER, that the foregoing restriction shall not apply to those



                                       3
<PAGE>

issuances by the Company to which the right of first offer does not apply
under Section 1.4 of the Right of First Refusal and Co-Sale Agreement dated
of even date herewith (the "RIGHT OF FIRST REFUSAL AND CO-SALE AGREEMENT") by
and among the Company, the Investors and certain additional shareholders of
the Company. In addition, upon the Company's satisfaction of each criterion
specified on SCHEDULE 1.5 and SCHEDULE 1.8 (or the Investors' written waiver
of the Company's obligation to satisfy any or all of such criteria), the
Company shall notify the Investors of such completion. Investors shall
reasonably determine whether such criteria have been satisfied, if at all,
within two (2) business days following receipt by the Investors of a written
notice of completion signed by the Company's Chief Financial Officer. If the
Investors reasonably determine that such criteria have not been satisfied,
the matter may be referred to arbitration in accordance with Section 8.10
hereof. If the Investors reasonably determine that such criteria have been
satisfied, the Investors shall, at the Company's sole option, use their best
efforts to secure within ninety (90) days from the completion date an
additional $3 million of financing from third party investors to purchase
shares of a yet undesignated preferred stock of the Company on substantially
the same terms and conditions as those pertaining to the purchase and sale of
Series B Preferred Stock as set forth herein and in the agreements
contemplated hereby, with the exception that the price per share shall be
determined based on at least a $10 million pre-money valuation and the
provisions pertaining to liquidation preference and anti-dilution shall
reflect such price (the "FUTURE EQUITY FINANCING"), and the Company may, at
its sole option, offer for purchase and sale such shares to such third
parties. Notwithstanding the foregoing, the Investors shall have no
obligation to invest in any Future Equity Financing. In addition, in
connection with the first Future Equity Financing the Company shall offer for
purchase and sale fifty percent (50%) of the total number of shares offered
in such Future Equity Financing to the Investors pursuant to the Right of
First Refusal and Co-Sale Agreement.

         2.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby

aware that any of its employees, officers or consultants are in violation
thereof, and the Company will use its best efforts to prevent any such
violation.

         2.10 PATENTS AND TRADEMARKS. To its knowledge (but without having
conducted any special investigation or patent search), the Company has
sufficient title and ownership of all patents, trademarks, service marks,
trade names, copyrights, trade secrets, information, proprietary rights and
processes necessary for its business as now conducted and as proposed to be
conducted without any conflict with or infringement of the rights of others.
SCHEDULE 2.10 contains a complete list of patents and pending patent
applications of the Company. There are no outstanding options, licenses, or
agreements of any kind relating to the foregoing, nor is the Company bound by

secrets, licenses, information, proprietary rights and processes of any other
person or entity. The Company has not received any communications alleging
that the Company has violated or, by conducting its business as proposed,
would violate any of the patents, trademarks, service marks, trade names,
copyrights or trade secrets or other proprietary rights of any other person
or entity. The Company is not aware that any of its employees is obligated
under any contract (including licenses, covenants or commitments of any

conflict with the Company's business as proposed to be conducted. Neither the
execution nor delivery of this Agreement, the Investors' Rights Agreement,
the Right of First Refusal and Co-Sale Agreement, the Technology Assignment
Agreement or the Voting 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 of such
employees is now obligated. The Company does not believe it is or will be
necessary to utilize any inventions of any of its employees (or people it
currently intends to hire) made prior to their employment by the Company.

         2.11 COMPLIANCE WITH OTHER INSTRUMENTS. The Company is not in
violation or default in any material respect of any provision of its Restated
Articles or Bylaws, or in any material respect of any instrument, judgment,
order, writ, decree or contract to which it is a party or by which it is
bound, or, to its knowledge, of any provision of any federal or state
statute, rule or regulation applicable to the Company. The execution,
delivery and performance of this Agreement, the Investors' Rights Agreement,
the Right of First Refusal and Co-Sale Agreement, the Technology Assignment
Agreement and the Voting Agreement, and the consummation of the transactions
contemplated hereby and thereby will not result in any such violation or be
in conflict with or constitute, with or without the passage of time and
giving of notice, either a default under any such provision, instrument,
judgment, order, writ, decree or contract or an 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

(iii) regarding any other form of acquisition, liquidation, dissolution or
winding up of the Company.

         2.13 RELATED-PARTY TRANSACTIONS. No employee, officer, or director
of the Company or member of his or her immediate family is indebted to the
Company, nor is the

<PAGE>

Company indebted (or committed to make loans or extend or guarantee credit)
to any of them. To the Company's knowledge, none of such persons has any
direct or indirect ownership interest in any firm or corporation with which
the Company is affiliated or with which the Company has a business
relationship, or any firm or corporation that competes with the Company,
except that employees, officers, or directors of the Company and members of
their immediate families may own stock in publicly traded companies that may

director of the Company is directly or indirectly interested in any material
contract with the Company.

         2.14 PERMITS. The Company has all franchises, permits, licenses, and
any similar authority 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

         2.16 DISCLOSURE. The Company has fully provided each Investor with
all the information that such Investor has requested for deciding whether to
purchase the Series A Preferred Stock and Series B Preferred Stock. To its
knowledge, neither this Agreement, the Investors' Rights Agreement, the

material fact or omits to state a material fact necessary to make the
statements herein or therein not misleading.

         2.17 BUSINESS PLAN. The Business Plan dated June, 1998, previously
delivered to each Investor has been prepared in good faith by the Company and
does not contain any untrue statement of a material fact nor does it omit to

faith and that the Company reasonably believes there is a reasonable basis
for such projections.

compliance with such leases and, to its knowledge, holds a valid leasehold
interest free of any liens, claims or encumbrances.

         2.21 LIABILITIES. The Company has delivered to each Investor its

                                      11
<PAGE>

         3.1  AUTHORIZATION. Such Investor has full power and authority to
enter into this Agreement, the Investors' Rights Agreement and the Voting
Agreement, and each such Agreement constitutes its valid and legally binding
obligation, enforceable in accordance with its terms.

         3.2  PURCHASE ENTIRELY FOR OWN ACCOUNT. This Agreement is made with
such Investor in reliance upon such Investor's representation to the Company,
which by such Investor's execution of this Agreement such Investor hereby
confirms, that the Series A Preferred Stock and Series B Preferred Stock to
be received by such Investor and the Common Stock issuable upon conversion
thereof (collectively, the "SECURITIES") will be acquired for investment for
such Investor's own account, not as a nominee or agent, and not with a view
to the resale or distribution of any part thereof, and that such Investor has
no present intention of selling, granting any participation in, or otherwise
distributing the same. By executing this Agreement, such Investor further
represents that such 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 Securities.

         3.3  DISCLOSURE OF INFORMATION. Such Investor represents that it has
had an opportunity to ask questions and receive answers from the Company
regarding the terms and conditions of the offering of the Series A Preferred
Stock and Series B Preferred Stock and the business, properties, prospects
and financial condition of the Company. The foregoing, however, does not
limit or modify the representations and warranties of the Company in Section
2 of this Agreement or the right of the Investors to rely thereon.

         3.4  INVESTMENT EXPERIENCE. Such Investor is an investor in
securities of companies in the development stage and acknowledges that it is
able to fend for itself, can bear the economic risk of its investment, and
has such knowledge and experience in financial or business matters that it is
capable of evaluating the merits and risks of the investment in the Series A
Preferred Stock and Series B Preferred Stock. If other than an individual,
Investor also represents it has not been organized for the purpose of
acquiring the Series A Preferred Stock and Series B Preferred Stock.

         3.5  ACCREDITED INVESTOR. Such Investor is an "accredited investor"
within the meaning of Securities and Exchange Commission ("SEC") Rule 501 of
Regulation D, as presently in effect.

         3.6  RESTRICTED SECURITIES. Such Investor understands that the
Securities it is purchasing are characterized as "restricted securities"
under the federal securities laws inasmuch as they are being acquired from
the Company in a transaction not involving a public offering and that under
such laws and applicable regulations such securities may be resold without
registration under the Act, only in certain limited circumstances. In this
connection, such Investor represents that it is familiar with SEC Rule 144,
as presently in effect, and understands the resale limitations imposed
thereby and by the Act.

         3.7  FURTHER LIMITATIONS ON DISPOSITION. Without in any way limiting
the representations set forth above, such Investor further agrees not to make
any disposition of all or any portion of the Securities unless and until the
transferee has agreed in writing for the



                                       12

benefit of the Company to be bound by this Section 3, the Investors' Rights
Agreement and the Voting Agreement provided and to the extent this Section
and such agreement are then applicable, and:

         (a) There is then in effect a Registration Statement under the Act
covering such proposed disposition and such disposition is made in accordance
with such Registration Statement; or

         (b) (i) Such Investor shall have notified the Company of the
proposed disposition and shall have furnished the Company with a detailed
statement of the circumstances surrounding the proposed disposition, and (ii)
if reasonably requested by the Company, such Investor shall have furnished
the Company with an opinion of counsel, reasonably satisfactory to the
Company that such disposition will not require registration of such shares
under the Act. It is agreed that the Company will not require opinions of
counsel for transactions made pursuant to Rule 144 except in unusual
circumstances.

         (c) Notwithstanding the provisions of paragraphs (a) and (b) above,
no such registration statement or opinion of counsel shall be necessary for
(i) a transfer by an Investor that is a partnership to a partner of such
partnership or a retired partner of such partnership who retires after the
date hereof, or to the estate of any such partner or retired partner, the
transfer by gift, will or intestate succession of any partner to his or her
spouse or to the siblings, lineal descendants or ancestors of such partner or
his or her spouse or (ii) a transfer to an Affiliate (as such term is defined
in Rule 12(b)(2) promulgated under the Securities Exchange Act of 1934, as
amended, if the transferee agrees in writing to be subject to the terms
hereof to the same extent as if he or she were an original Investor hereunder.

         3.8 LEGENDS. It is understood that the certificates evidencing the
Securities may bear one or all of the following legends:

         (a) "These securities have not been registered under the Securities
Act of 1933, as amended. They may not be sold, offered for sale, pledged or
hypothecated in the absence of a registration statement in effect with
respect to the securities under such Act or an opinion of counsel
satisfactory to the Company that such registration is not required or unless
sold pursuant to Rule 144 of such Act."

Closing and, if the Fee Limitation is not reached in connection with that
closing, at subsequent closings until the Company has paid up to the Fee
Limitation. If any action at law or in equity is necessary to enforce or
interpret the terms of this Agreement, the Investors' Rights Agreement, the
Voting Agreement or the Restated Articles, the prevailing party shall be
entitled to reasonable attorney's fees, costs and necessary disbursements in
addition to any other relief to which such party may be entitled.

         8.9  AMENDMENTS AND WAIVERS. Any term of this Agreement may be

prospectively), only with the written consent of the Company and the holders
of a majority of the Common Stock issued upon conversion of the Series A
Preferred Stock and Series B Preferred Stock or issuable upon conversion of

waiver effected in accordance with this paragraph shall be binding upon each

such securities are convertible), each future holder of all such securities,
and the Company.

         8.10 DISPUTES. If the parties are unable, after good faith
negotiations, which each hereby covenants to undertake, to resolve any
dispute arising between them within fifteen (15) days after notice is given
of such dispute, then the dispute will be referred to arbitration (which the
parties agree is the exclusive means of resolving any such dispute) before
one (1) arbitrator in Los Angeles County, California, or any other place
mutually agreed upon by the parties hereto, in accordance with the applicable
rules then in effect of the Judicial Arbitration and Mediation Service (the
"JAMS Rules") (or any other form of arbitration mutually acceptable to the
parties). The determination made in accordance with the JAMS rules shall be
delivered in writing to the parties hereto and shall be final, binding and
conclusive on the parties hereto, and the amount of the claim, if any,
determined to exist shall be a valid claim and no further remedy shall be
available to either party with respect to such dispute and judgment may be
entered upon such decision in accordance with applicable law in any court
having jurisdiction thereof. The arbitration award shall include (i) a
provision that the prevailing party in such arbitration recover its costs
relating to the arbitration and reasonable attorneys' fees from the other
party, (ii) the amount of such costs and fees, and (iii) an order that the
losing party pay the fees and expenses of the arbitrator.

         8.11 SEVERABILITY. If one or more provisions of this Agreement are
held to be unenforceable under applicable law, such provision shall be
excluded from this Agreement and the balance of the Agreement shall be
interpreted as if such provision were so excluded and shall be enforceable in
accordance with its terms.

         8.12 AGGREGATION OF STOCK. All shares of the Preferred Stock held or
acquired by affiliated entities or persons shall be aggregated together for
the purpose of determining the availability of any rights under this
Agreement.

         8.13 ENTIRE AGREEMENT. This Agreement and the documents referred to
herein constitute the entire agreement among the parties and no party shall
be liable or bound to any other party in any manner by any warranties,
representations, or covenants except as specifically set forth herein or

                                 NETZERO, INC.
                   SERIES C PREFERRED STOCK PURCHASE AGREEMENT

       This Series C Preferred Stock Purchase Agreement (the "Stock Purchase
Agreement") is made as of __________________, by and between NetZero, Inc.,
a California corporation (the "Company"), and David C. Bohnett ("Optionee"
or "Purchaser").

       All capitalized terms in this Agreement shall have the meaning assigned
to them in this Agreement or in the attached Appendix.

   A.  EXERCISE OF OPTION

       1.  EXERCISE.  Optionee hereby purchases 150,000 shares of Series C
Preferred Stock (the "Purchased Shares") pursuant to that certain option (the
"Option") granted Optionee on December 4, 1998 (the "Grant Date") to purchase
up to 150,000 shares of Series C Preferred Stock (the "Option Shares") at the
exercise price of $0.6446 per share (the "Exercise Price").

       2.  PAYMENT.  Concurrently with the delivery of this Agreement to the
Company, Optionee shall pay the Exercise Price for the Purchased Shares in
accordance with the provisions of the Option Agreement and shall deliver
whatever additional documents may be required by the Option Agreement as a
condition for exercise, together with a duly-executed blank Assignment
Separate from Certificate (in the form attached hereto as Exhibit I with
respect to the Purchased Shares.

       3.  SHAREHOLDER RIGHTS.  Until such time as the Company exercises the
Repurchase Right, Optionee (or any successor in interest deriving their claim
of ownership through a Permitted Transfer from Optionee, such successor an
"Owner") shall have all the rights of a shareholder with respect to the
Purchased Shares as set forth in the Company's Articles of Incorporation, as
amended (including voting, dividend, liquidation and conversion rights),
subject, however, to the transfer restrictions of Article B.

   B.  SECURITIES LAW COMPLIANCE

       1.  EXEMPTION FROM REGISTRATION.  Purchaser acknowledges that the
Purchased Shares are not being registered under the Securities Act of 1933,
as amended (the "1933 ACT"), based, in part, on reliance that the issuance of
the Purchased Shares is exempt from registration under Section 4(2) of the
1933 Act as not involving any public offering. Purchaser further acknowledges
that the Company's reliance on such exemption is predicated, in part, on the
representations set forth below made by Purchaser to the Company:

           (a)  Purchaser is acquiring the Purchased Shares solely for his
own account, for investment purposes only, and not with an intent to sell,
or for resale in connection with any distribution of all or any portion of
the Shares within the meaning of the 1933 Act;

                                      1
<PAGE>

           (b)  Purchaser is an "Accredited Investor" as that term is defined
in Rule 501 of the General Rules and Regulations under the Securities Act of
1933;

           (c)  In evaluating the merits and risks of an investment in the
Purchased Shares, Purchaser has relied upon the advice of Purchaser's legal
counsel, tax advisors, and/or other investment advisors;

           (d)  Purchaser is experienced in evaluating and investing in
companies such as the Company. In addition, Purchaser has a preexisting
business relationship with the Company. Purchaser has been given access to
all books, records and other information of the Company which Purchaser has
desired to review and analyze in connection with Purchaser's purchase of the
Purchased Shares hereunder;

           (e)  Purchaser is aware that an investment in securities of a
closely held corporation such as the Company is non-marketable,
non-transferable and will require Purchaser's capital to be invested for an
indefinite period of time, possibly without return. Purchaser has no need for
liquidity in this investment, has the ability to bear the economic risk of
this investment, and can afford a complete loss of the entire purchase price
paid for the Purchased Shares;

           (f)  Purchaser understands that the Shares being purchased
hereunder are characterized as "restricted securities" under the federal
securities laws since the Purchased Shares are being acquired from the
Company in a transaction not involving a public offering and that under such
laws and applicable regulations such securities may be resold without
registration under the 1933 Act only in certain limited circumstances.
Purchaser understands that the Company has no obligation to file a
registration statement under the 1933 Act for the Purchased Shares or to
otherwise assist Purchaser in complying with any exemption from registration.
Purchaser represents that Purchaser is familiar with Rule 144 promulgated
under the 1933 Act, as presently in effect, and understands the resale
limitations imposed thereby and by the 1933 Act; and

           (g)  At no time was an oral representation made to Purchaser
relating to the purchase of the Purchased Shares or was Purchaser presented
with or solicited by any leaflet, public or promotional material, newspaper
or magazine article, radio or television advertisement or any other form of
general advertising relating to the purchase hereunder.

       2.  DISPOSITION OF PURCHASED SHARES. Purchaser hereby agrees that
Purchaser shall make no disposition of the Purchased Shares unless and until:

           (a)  Purchaser shall have notified the Company of the proposed
disposition and provided a written summary in reasonable detail of the terms
and conditions of the proposed disposition;

           (b)  Purchaser shall have complied with all requirements of this
Agreement applicable to the disposition of the Shares;

                                         2
<PAGE>

           (c)  Purchaser shall have provided the Company with reasonable
written assurances, in form and substance satisfactory to the Company, that
(i) the proposed disposition does not require registration or qualification
of the Shares under the 1933 Act or any state securities laws or (ii) all
appropriate action necessary for compliance with the registration
requirements of the 1933 Act or any state securities laws or of any exemption
from registration available under the 1933 Act (including Rule 144) or any
state securities laws has been taken; and

           (d)  Purchaser shall have provided the Company with reasonable
written assurances, in form and substance satisfactory to the Company, that
the proposed disposition will not result in the contravention of any transfer
restrictions applicable to the Shares.

       The Company shall NOT be required (i) to transfer on its books any
Shares which have been sold or transferred in violation of the provisions of
this Article II NOR (ii) to treat as the owner of the Shares, or otherwise to
accord voting, dividend or liquidation rights to, any transferee to whom the
Shares have been transferred in contravention of this Agreement.

       3.  RESTRICTIVE LEGENDS. In order to reflect the restrictions on
disposition of the Purchased Shares, the stock certificates for the Purchased
Shares will be endorsed with restrictive legends, including the following
legends:

           (i)  "THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD,
OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED UNLESS THERE
IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH
SECURITIES OR THE ISSUER RECEIVES AN OPINION OF COUNSEL SATISFACTORY TO IT
STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND
PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT."

           (ii) "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
THE TERMS AND CONDITIONS OF AN INVESTOR'S RIGHTS AGREEMENT AMONG THE ISSUER,
THE HOLDER OF THE SECURITIES EVIDENCED HEREBY (OR SUCH HOLDER'S PREDECESSOR
IN INTEREST) AND CERTAIN OTHER SHAREHOLDERS WHICH MAY RESTRICT THE
DISPOSITION OF SUCH SHARES FOLLOWING A PUBLIC OFFERING OF THE COMPANY'S
SECURITIES."

           (iii) Any legends required by state securities laws.

       C.  REPURCHASE RIGHT

           1.  GRANT. The Company is hereby granted the right (the
"Repurchase Right"), exercisable at any time during the sixty (60) day period
following the date Optionee ceases for any reason to remain in Service or (if
later) during the sixty (60) day period following the execution date of this
Agreement, to repurchase at the Exercise Price any or all of the Purchased
Shares in which Optionee is not, at the time of his or her cessation of
Service, vested

                                      3
<PAGE>

in accordance with the Vesting Schedule applicable to those shares or the
special vesting acceleration provisions of Paragraph C.6 of this Agreement
(such shares to be hereinafter referred to as the "Unvested Shares").

           2. EXERCISE OF THE REPURCHASE RIGHT. The Repurchase Right shall be
exercisable by written notice delivered to each Owner of the Unvested Shares
prior to the expiration of the sixty (60) day exercise period. The notice
shall indicate the number of Unvested Shares to be repurchased and the date
on which the repurchase is to be effected, such date to be not more than
thirty (30) days after the date of such notice. The certificates representing
the Unvested Shares to be repurchased shall be delivered to the Company on or
before the close of business on the date specified for the repurchase.
Concurrently with the receipt of such stock certificates, the Company shall
pay to Owner, in cash or cash equivalents (including the cancellation of any
purchase-money indebtedness), an amount equal to the Exercise Price
previously paid for the Unvested Shares which are to be repurchased from
Owner.

           3. TERMINATION OF THE REPURCHASE RIGHT. The Repurchase Right shall
terminate with respect to any Unvested Shares for which it is not timely
exercised under Paragraph C.2. In addition, the Repurchase Right shall
terminate and cease to be exercisable with respect to any and all Purchased
Shares in which Optionee vests in accordance with the Vesting Schedule. All
Purchased Shares as to which the Repurchase Right lapses shall, however,
remain subject to the Investors' Rights Agreement.

           4. AGGREGATE VESTING LIMITATION. If the Option is exercised in
more than one increment so that Optionee is a party to one or more other
Stock Purchase Agreements (the "Prior Purchase Agreements") which are
executed prior to the date of this Agreement, then the total number of
Purchased Shares as to which Optionee shall be deemed to have a fully-vested
interest under this Agreement and all Prior Purchase Agreements shall not
exceed in the aggregate the number of Purchased Shares in which Optionee
would otherwise at the time be vested, in accordance with the Vesting
Schedule, had all the Purchased Shares (including those acquired under the
Prior Purchase Agreements) been acquired exclusively under this Agreement.

           5. RECAPITALIZATION. Any new, substituted or additional securities
or other property (including cash paid other than as a regular cash dividend)
which is by reason of any Recapitalization distributed with respect to the
Purchased Shares shall be immediately subject to the Repurchase Right and any
escrow requirements hereunder, but only to the extent the Purchased Shares
are at the time covered by such right or escrow requirements. Appropriate
adjustments to reflect such distribution shall be made to the number and/or
class of Purchased Shares subject to this Agreement and to the price per
share to be paid upon the exercise of the Repurchase Right in order to
reflect the effect of any such Recapitalization upon the Company's capital
structure; provided, however, that the aggregate purchase price shall remain
the same.

<PAGE>

           6. CORPORATE TRANSACTION.

              (a) The Repurchase Right shall automatically terminate in its
entirety, and all the Purchased Shares shall vest in full, immediately prior
to the consummation of any Corporate Transaction, except to the extent the
Repurchase Right is to be assigned to the successor entity in such Corporate
Transaction.

              (b) To the extent the Repurchase Right remains in effect
following a Corporate Transaction, such right shall apply to any new
securities or other property (including any cash payments) received in
exchange for the Purchased Shares in consummation of the Corporate
Transaction, but only to the extent the Purchased Shares are at the time
covered by such right. Appropriate adjustments shall be made to the price per
share payable upon exercise of the Repurchase Right to reflect the effect of
the Corporate Transaction upon the Company's capital structure; provided,
however, that the aggregate purchase price shall remain the same. The new
securities or other property (including any cash payments) issued or
distributed with respect to the Purchased Shares in consummation of the
Corporate Transaction shall be immediately deposited in escrow with the
Company (or the successor entity) and shall not be released from escrow until
Optionee vests in such securities or other property in accordance with the
same Vesting Schedule in effect for the Purchased Shares.

              (c) The Repurchase Right shall also terminate on an accelerated
basis, and the Purchased Shares shall immediately vest in full, in the event
Optionee voluntarily resigns from the Board at the request of the Company's
Board of Directors or controlling shareholders, if Optionee is involuntarily
removed from the Board for any reason other than Misconduct, or if Optionee
is not re-elected to the Board for any reason other than Misconduct.

       D. SPECIAL TAX ELECTION

          The acquisition of the Purchased Shares may result in adverse tax
consequences which may be avoided or mitigated by filing an election under
Code Section 83(b). Such election must be filed within thirty (30) days after
the date of this Agreement. A description of the tax consequences applicable
to the acquisition of the Purchased Shares and the form for making the Code
Section 83(b) election are set forth in Exhibit II. OPTIONEE SHOULD CONSULT
WITH HIS OR HER TAX ADVISOR TO DETERMINE THE TAX CONSEQUENCES OF ACQUIRING
THE PURCHASED SHARES AND THE ADVANTAGES AND DISADVANTAGES OF FILING THE CODE
SECTION 83(b) ELECTION. OPTIONEE ACKNOWLEDGES THAT IT IS OPTIONEE'S SOLE
RESPONSIBILITY, AND NOT THE COMPANY'S, TO FILE A TIMELY ELECTION UNDER CODE
SECTION 83(b), EVEN IF OPTIONEE REQUESTS THE COMPANY OR ITS REPRESENTATIVES
TO MAKE THIS FILING ON HIS OR HER BEHALF.

       E. GENERAL PROVISIONS

          1. ASSIGNMENT. The Company may assign the  Repurchase  Right to any
person or entity  selected by the Board, including (without limitation) one
or more shareholders of the Company.

                                        5
<PAGE>

          2. NO EMPLOYMENT OR SERVICE CONTRACT. Nothing in this Agreement or
in the Plan shall confer upon Optionee any right to continue in Service for
any period of specific duration or interfere with or otherwise restrict in
any way the rights of the Company (or any Parent or Subsidiary employing or
retaining Optionee) or of Optionee, which rights are hereby expressly
reserved by each, to terminate Optionee's Service at any time for any reason,
with or without cause.

          3. NOTICES. Any notice required to be given under this Agreement
shall be in writing and shall be deemed effective upon personal delivery or
upon deposit in the U.S. mail, registered or certified, postage prepaid and
properly addressed to the party entitled to such notice at the address
indicated below such party's signature line on this Agreement or at such
other address as such party may designate by ten (10) days advance written
notice under this paragraph to all other parties to this Agreement.

          4. NO WAIVER. The failure of the Company in any instance to
exercise the Repurchase Right shall not constitute a waiver of any other
repurchase rights and/or rights of first refusal that may subsequently arise
under the provisions of this Agreement or any other agreement between the
Company and Optionee. No waiver of any breach or condition of this Agreement
shall be deemed to be a waiver of any other or subsequent breach or
condition, whether of like or different nature.

          5. CANCELLATION OF SHARES. If the Company shall make available, at
the time and place and in the amount and form provided in this Agreement, the
consideration for the Purchased Shares to be repurchased in accordance with
the provisions of this Agreement, then from and after such time, the person
from whom such shares are to be repurchased shall no longer have any rights
as a holder of such shares (other than the right to receive payment of such
consideration in accordance with this Agreement). Such shares shall be deemed
purchased in accordance with the applicable provisions hereof, and the
Company shall be deemed the owner and holder of such shares, whether or not
the certificates therefor have been delivered as required by this Agreement.

          6. OPTIONEE UNDERTAKING. Optionee hereby agrees to take whatever
additional action and execute whatever additional documents the Company may
deem necessary or advisable in order to carry out or effect one or more of
the obligations or restrictions imposed on either Optionee or the Purchased
Shares pursuant to the provisions of this Agreement.

          7. AGREEMENT IS ENTIRE CONTRACT. This Agreement and the Option
Agreement constitute the entire contract between the parties hereto with
regard to the subject matter hereof.

          8. GOVERNING LAW. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of California without
resort to that State's conflict-of-laws rules.

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

          10. SUCCESSORS AND ASSIGNS. The provisions of this Agreement shall
inure to the benefit of, and be binding upon, the Company and its successors
and assigns and upon Optionee, Optionee's permitted assigns and the legal
representatives, heirs and legatees of Optionee's estate, whether or not any
such person shall have become a party to this Agreement and have agreed in
writing to join herein and be bound by the terms hereof.

                   SERIES B PREFERRED STOCK PURCHASE AGREEMENT

                  This Series B Preferred Stock Purchase Agreement (the
"AGREEMENT") is made as of January 1, 1999, by and between NetZero, Inc., a
California corporation (the "COMPANY"), and David C. Bohnett Living Trust Dtd
11/22/96 ("PURCHASER").

                  WHEREAS, Purchaser wishes to purchase shares of Series B
Preferred Stock of the Company upon the terms and subject to the conditions
of this Agreement.

                  NOW THEREFORE, in consideration of the premises and the
mutual covenants contained herein and other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, the parties
agree as follows:

I.       PURCHASE OF SHARES

                  1.1 PRICE. Purchaser hereby agrees to purchase 67,507
shares of Series B Preferred Stock of the Company (the "Shares") at a price
of $0.2222 per Share. The aggregate purchase price for the Shares shall be
$15,000.01.

                  1.2 FORM OF PAYMENT. Purchaser shall pay the purchase price
for the Shares by delivering good funds in United States dollars to the
Company. Such delivery of funds shall be made against delivery by the Company
of a certificate for the Shares.

                  1.3 RIGHT, PREFERENCES AND PRIVILEGES. The Series B
Preferred Stock of the Company shall have the rights, preferences and
privileges set forth in the Company's Amended and Restated Articles of
Incorporation filed with the Secretary of the State of California on
September 3, 1998.

II.      SECURITIES LAW COMPLIANCE

                  2.1 EXEMPTION FROM REGISTRATION. Purchaser acknowledges
that the Shares are not being registered under the Securities Act of 1933, as
amended (the "1933 ACT"), based, in part, on reliance that the issuance of
the Shares is exempt from registration under Section 4(2) of the 1933 Act as
not involving any public offering. Purchaser further acknowledges that the
Company's reliance on such exemption is predicated, in part, on the
representations set forth below made by Purchaser to the Company:

                       (a) Purchaser is acquiring the Shares solely for his
own account, for investment purposes only, and not with an intent to sell, or
for resale in connection with any distribution of all or any portion of the
Shares within the meaning of the 1933 Act;

                       (b) Purchaser is an "Accredited Investor" as that term
is defined in Rule 501 of the General Rules and Regulations under the
Securities Act of 1933;

                       (c) In evaluating the merits and risks of an
investment in the Shares, Purchaser has relied upon the advice of Purchaser's
legal counsel, tax advisors, and/or other investment advisors;

<PAGE>

                       (d) Purchaser is experienced in evaluating and
investing in companies such as the Company. In addition, Purchaser has a
preexisting business relationship with the Company. Purchaser has been given
access to all books, records and other information of the Company which
Purchaser has desired to review and analyze in connection with Purchaser's
purchase of the Shares hereunder;

                       (e) Purchaser is aware that an investment in
securities of a closely held corporation such as the Company is
non-marketable, non-transferable and will require Purchaser's capital to be
invested for an indefinite period of time, possibly without return. Purchaser
has no need for liquidity in this investment, has the ability to bear the
economic risk of this investment, and can afford a complete loss of the
entire purchase price paid for the Shares;

                       (f) Purchaser understands that the Shares being
purchased hereunder are characterized as "restricted securities" under the
federal securities laws since the Shares are being acquired from the Company
in a transaction not involving a public offering and that under such laws and
applicable regulations such securities may be resold without registration
under the 1933 Act only in certain limited circumstances. Purchaser
understands that the Company has no obligation to file a registration
statement under the 1933 Act for the Shares or to otherwise assist Purchaser
in complying with any exemption from registration. Purchaser represents that
Purchaser is familiar with Rule 144 promulgated under the 1933 Act, as
presently in effect, and understands the resale limitations imposed thereby
and by the 1933 Act; and

                       (g) At no time was an oral representation made to
Purchaser relating to the purchase of the Shares or was Purchaser presented
with or solicited by any leaflet, public or promotional material, newspaper
or magazine article, radio or television advertisement or any other form of
general advertising relating to the purchase hereunder.

                  2.2 DISPOSITION OF SHARES. Purchaser hereby agrees that
Purchaser shall make no disposition of the Shares unless and until:

                       (a) Purchaser shall have notified the Company of the
proposed disposition and provided a written summary in reasonable detail of
the terms and conditions of the proposed disposition;

                       (b) Purchaser shall have complied with all
requirements of this Agreement applicable to the disposition of the Shares;

                       (c) Purchaser shall have provided the Company with
reasonable written assurances, in form and substance satisfactory to the
Company, that (i) the proposed disposition does not require registration or
qualification of the Shares under the 1933 Act or any state securities laws
or (ii) all appropriate action necessary for compliance with the registration
requirements of the 1933 Act or any state securities laws or of any exemption
from registration available under the 1933 Act (including Rule 144) or any
state securities laws has been taken; and

                       (d) Purchaser shall have provided the Company with
reasonable written assurances, in form and substance satisfactory to the
Company, that the proposed

<PAGE>

disposition will not result in the contravention of any transfer restrictions
applicable to the Shares.

                  The Company shall NOT be required (i) to transfer on its
books any Shares which have been sold or transferred in violation of the
provisions of this Article II NOR (ii) to treat as the owner of the Shares,
or otherwise to accord voting, dividend or liquidation rights to, any
transferee to whom the Shares have been transferred in contravention of this
Agreement.

                  2.3 RESTRICTIVE LEGENDS. In order to reflect the
restrictions on disposition of the Shares, the stock certificates for the
Shares will be endorsed with restrictive legends, including the following
legends:

                       (i) "THE SHARES EVIDENCED BY THIS CERTIFICATE HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE
SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED UNLESS
THERE IS AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH
SECURITIES OR THE ISSUER RECEIVES AN OPINION OF COUNSEL SATISFACTORY TO IT
STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM THE REGISTRATION AND
PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT."

                       (ii) "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE
SUBJECT TO THE TERMS AND CONDITIONS OF AN INVESTOR'S RIGHTS AGREEMENT AMONG
THE ISSUER, THE HOLDER OF THE SECURITIES EVIDENCED HEREBY (OR SUCH HOLDER'S
PREDECESSOR IN INTEREST) AND CERTAIN OTHER SHAREHOLDERS WHICH MAY RESTRICT
THE DISPOSITION OF SUCH SHARES FOLLOWING A PUBLIC OFFERING OF THE COMPANY'S
SECURITIES."

                       (iii) Any legends required by state securities laws.

III.     GENERAL PROVISIONS.

                  3.1 NO EMPLOYMENT OR SERVICE CONTRACT. Nothing in this
Agreement shall confer upon Purchaser any right to continue in the service of
the Company (or any parent or subsidiary corporation of the Company employing
or retaining Purchaser) for any period of specific duration or interfere with
or restrict in any way the rights of the Company (or any parent or subsidiary
corporation of the Company employing or retaining Purchaser) or Purchaser,
which rights are hereby expressly reserved by each, to terminate the Employee
status of Purchaser at any time for any reason whatsoever, with or without
cause.

                  3.2 NOTICES. Any notice required hereunder shall be given
in writing and shall be deemed effective upon personal delivery or upon
deposit in the United States mail, registered or certified, postage prepaid
and addressed to the party entitled to such notice at the address indicated
below such party's signature line on this Agreement or at such other address
as such party may designate by ten days advance written notice under this
Section 3.2 to all other parties to this Agreement.

<PAGE>

                  3.3 NO WAIVER. No waiver of any breach or condition of this
Agreement shall be deemed to be a waiver of any other or subsequent breach or
condition, whether of like or different nature.

                  3.4 PURCHASER UNDERTAKING. Purchaser hereby agrees to take
whatever additional action and execute whatever additional documents the
Company may in its judgment deem necessary or advisable in order to carry out
or effect one or more of the obligations or restrictions imposed on either
Purchaser or the Shares pursuant to the express provisions of this Agreement.

                  3.6 AGREEMENT IS ENTIRE CONTRACT. This Agreement
constitutes the entire contract between the parties hereto with regard to the
subject matter hereof.

                  3.7 GOVERNING LAW. This Agreement shall be governed by, and
construed in accordance with, the laws of the State of California, as such
laws are applied to contracts entered into and performed in such state
without resort to that state's conflict-of-laws rules.

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

                  3.9 SUCCESSORS AND ASSIGNS. The provisions of this
Agreement shall inure to the benefit of, and be binding upon, the Company and
its successors and assigns and Purchaser and Purchaser's legal
representatives, heirs, legatees, distributees, assigns and transferees by
operation of law, whether or not any such person shall have become a party to
this Agreement and have agreed in writing to join herein and be bound by the
terms and conditions hereof.

                  3.10 RIGHT TO SPECIFIC PERFORMANCE. Purchaser agrees that
the Company shall be entitled to a decree of specific performance of the
terms hereof or an injunction restraining violation of this Agreement, said
right to be in addition to any other remedies available to the Company.

                  3.11 SEVERABILITY. If one or more provisions of this
Agreement are held to be unenforceable under applicable law, such provision
shall be excluded from this Agreement and the balance of the Agreement shall
be interpreted as if such provision were so excluded and shall be enforceable
in accordance with its terms.

               CONVERTIBLE SUBORDINATED NOTE AND WARRANT PURCHASE
                                    AGREEMENT


     This Convertible Subordinated Note and Warrant Purchase Agreement (this
"Agreement") is made and entered into as of January 15, 1999 by and among
NetZero, Inc., a California corporation (the "Company"), and the entities
listed on Exhibit A attached hereto (the "Purchasers").

     The Company desires to issue and sell and the Purchasers desire to
purchase promissory notes in the form attached hereto as EXHIBIT B (the
"Notes") and warrants to purchase shares of capital stock of the Company in
the form attached hereto as EXHIBIT C (the "Warrants") as further described
herein.

     In consideration of the mutual promises contain herein, the parties
agree as follows:

     1. Sale of Notes and Warrants:

        1.1 COMMITMENT. Subject to the terms and conditions of this
Agreement, the Purchasers agree to purchase from the Company and the Company
agrees to sell and issue to the Purchasers the Notes and the Warrants. The
purchase price of each Note shall be equal to 100% of the principal amount of
such Note as specified on the Schedule of Purchasers attached hereto as
EXHIBIT A and the purchase price of the Warrant to be issued to each
Purchaser shall be as specified on the Schedule of Purchasers, for a purchase
price for each Warrant of $0.01 per share issuable upon exercise of the
Warrant, which amount the parties have determined in good faith, after
consultation with their advisors, to be the fair value of each Warrant. For
purposes of this Agreement, an "Equity Financing" shall have the meaning
given to it in the Note.

        1.2 CLOSING. The closing of the purchase and sale of the Notes and
the Warrants hereunder shall be made pursuant to one or more closings (each
of which is a "Closing") held within 60 days of the date hereof, with the
first such closing to be held at the offices of the Company, at 10:00 a.m. on
January 15, 1999 (the "First Closing') or at such other time and place as the
parties shall agree (the date of a Closing is hereinafter referred to as a
"Closing Date"). At the Closing, the Company shall deliver to each Purchaser
the Note and the Warrant to be purchased by such Purchaser against payment of
the purchase price for the Note and the Warrant by cash, check or wire
transfer to a bank account designated by the Company. Any person or entity
who purchases any Notes or Warrants after the First Closing shall become a
party to this Agreement and shall be added to the list of purchasers. The
Company's agreements with each of the Purchasers are separate agreements and
the sale of the Notes and the Warrants to each Purchaser are separate sales.

     2. PURCHASE OF STOCK:

        2.1 EQUITY FINANCING. If an Equity Financing is completed on or
before June 30, 1999, (a) up to the total amount of the unpaid principal
amount of the Note and any accrued but unpaid interest will automatically be
converted into shares of the Company's capital

<PAGE>

stock (the "New Stock") sold in the Financing upon the terms and conditions
set forth in the Note and (b) at the closing of an Equity Financing, each
Purchaser will execute a stock purchase agreement substantially similar to
that executed by other purchasers of the New Stock in an Equity Financing. If
the Company does not complete an Equity Financing on or before June 30, 1999,
(x) the unpaid principal amount of the Note and any accrued but unpaid
interest will automatically be converted into shares of the Company's Series
B Preferred Stock in the' manner set forth in the Note attached hereto as
EXHIBIT B.

          2.2 CONDITIONS TO CLOSING; REGISTRATION RIGHTS. The obligations of
the Company to issue shares of New Stock and the obligations of each
Purchaser to purchase such stock as described in Section 2.1 above are
subject to the conditions that:

               (a) The Company shall have obtained all requisite approvals of
and made all required filings with applicable federal and state securities
and corporate law authorities;

               (b) The Company shall have obtained all appropriate Board and
stockholder consents, waivers and approvals required in connection with the
transaction;

               (c) Each Purchaser and the Company shall have executed a stock
purchase agreement covering the sale of shares of New Stock substantially
similar to that executed by the other purchasers in the Equity Financing; and

               (d) Such stock purchase agreement shall grant each Purchaser
rights with respect to registration under the Securities Act of 1933, as
amended (the "Securities Act"), of shares of New Stock or of shares of Common
Stock issued or issuable to such Purchaser upon conversion of the New Stock,
as the case may be, issued upon conversion of such Purchaser's Note, which
registration rights shall be substantially identical to those granted to the
other purchasers in the Equity Financing.

        2.3 BEST EFFORTS. The Company and the Purchasers will use their best
efforts promptly to fulfill all of the conditions described in Section 2.2
above.

        2.4 ISSUANCE OF SECURITIES ON CONVERSION. As soon as practicable
after conversion of each Note, the Company at its expense will cause to be
issued in the name of and delivered to the holder of the Note, a certificate
or certificates for the number of fully paid and non-assessable shares of New
Stock of the Company to which that holder shall be entitled on such
conversion, together with any other securities and property to which the
holder is entitled on conversion under the terms of this Agreement. No
fractional shares will be issued on conversion of the Note. If on conversion
of the Note a fraction of a share results, the Company will pay the cash
value of that fractional share, calculated on the basis of the applicable
conversion price.

     3. REPRESENTATIONS OF THE PURCHASERS:

        Each Purchaser hereby represents and warrants to the Company that:


                                     -2-


<PAGE>

        3.1 AUTHORIZATION. This Agreement, when executed and delivered by the
Purchaser, will constitute valid and legally binding obligations of the
Purchaser, enforceable in accordance with its terms, except as limited by
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance, and any other laws of general application affecting enforcement
of creditors' rights generally, and as limited by laws relating to the
availability of a specific performance, injunctive relief, or other equitable
remedies.

        3.2 PURCHASE ENTIRELY FOR OWN ACCOUNT; ACCREDITED INVESTOR. This
Agreement is made with the Purchaser in reliance upon the Purchaser's
representation to the Company, which by the Purchaser's execution of this
Agreement the Purchaser hereby confirms, that (i) the Notes, the Warrants,
the Preferred Stock issuable upon conversion of the Notes and exercise of the
Warrants and the Common Stock issuable upon conversion of the Preferred Stock
(collectively the "Securities") to be acquired by the Purchaser will be
acquired for investment for the Purchaser's own account, not as a nominee or
agent, and not with a view to the resale or distribution of any part thereof,
and that the Purchaser has no present intention of selling, granting any
participation in, or otherwise distributing the same and (ii) that the
Purchaser is an "accredited investor" as such term is defined under the
Securities Act. By executing this Agreement, the Purchaser further represents
that the Purchaser does not presently 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 Securities. The Purchaser represents that it has full power and authority
to enter into this Agreement. Either (i) the Purchaser has not been formed
for the specific purpose of acquiring the Securities or (ii) if the Purchaser
has been formed for the specific purpose of acquiring the Securities, each
person or entity that has an interest in the Purchaser is an accredited
investor.

        3.3 DISCLOSURE OF INFORMATION. The Purchaser has had an opportunity
to discuss the Company's business, management, financial affairs and the
terms and conditions of the offering of the Stock with the Company's
management and has had an opportunity to review the Company's facilities. The
Purchaser understands that such discussions, as well as the written
information issued by the Company, were intended to describe the aspects of
the Company's business which it believes to be material.

        3.4 RESTRICTED SECURITIES. The Purchaser understands that the
Securities have not been, and will not be, registered under the Securities
Act, by reason of a specific exemption from the registration provisions of
the Securities Act which depends upon, among other things, the bona fide
nature of the investment intent and the accuracy of the Purchaser's
representations as expressed herein. The Purchaser understands that the
Securities are "restricted securities" under applicable U.S. federal and
state securities laws and that, pursuant to these laws, the Purchaser must
hold the Securities indefinitely unless they are registered with the
Securities and Exchange Commission and qualified by state authorities, or an
exemption from such registration and qualification requirements is available.
The Purchaser acknowledges that the Company has no obligation to register or
qualify the Securities for resale. The Purchaser further acknowledges that if
an exemption from registration or qualification is available, it may be
conditioned on various requirements including, but not limited to, the time
and manner of sale, the holding period for the Securities, and on
requirements relating to the Company which are outside of the


                                     -3-

<PAGE>

Purchaser's control, and which the Company is under no obligation and may not
be able to satisfy.

        3.5 NO PUBLIC MARKET. The Purchaser understands that no public market
now exists for any of the securities issued by the Company, and that the
Company has made no assurances that a public market will ever exist for the
Securities.

        3.6 LEGENDS. The Purchaser understands that the Securities, and any
securities issued in respect of or exchange for the Securities, may bear one
or all of the following legends:

               (a) "THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE BEEN ACQUIRED FOR

DISTRIBUTION THEREOF. NO SUCH SALE OR DISPOSITION MAY BE EFFECTED WITHOUT AN
EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR AN OPINION OF COUNSEL IN
A FORM SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED

               (b) Any legend required by the Blue Sky laws of any state to
the extent such laws are applicable to the shares represented by the
certificate so legended.

        3.7 LEGAL ADVICE. The Purchaser has had the opportunity to consult
with his or her counsel regarding the matters relevant to this Agreement and
the transactions contemplated hereby.

     4. GENERAL PROVISIONS:

THIS SUBORDINATED CONVERTIBLE PROMISSORY NOTE AND THE SECURITIES ISSUABLE
HEREUNDER HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AND HAVE
BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH,
THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISPOSITION MAY BE EFFECTED

                                                               JANUARY 15, 1999
                                                   WESTLAKE VILLAGE, CALIFORNIA

                                  NETZERO, INC.

                    CONVERTIBLE SUBORDINATED PROMISSORY NOTE

         FOR THE VALUE RECEIVED, NetZero, Inc., a California corporation (the
"Company"), promises to pay to _______________________________________________
("Holder"), the principal sum of $___________. Interest shall accrue from the
date of this note on the unpaid principal amount at the rate of eight percent
(8.00%) per annum until paid, compounded annually. Such principal amount,
together with accrued but unpaid interest, shall be payable on demand by the
Holder of this Note after June 30, 1999, except as otherwise set forth below
or unless earlier converted in accordance with Section 2 of this Note. Any
term not otherwise defined herein shall have the meaning given to it in that
certain Convertible Subordinated Promissory Note Purchase Agreement dated as
of the date hereof.

         1. PAYMENT. All payments shall be made in lawful tender of the
United States of America at such place as the Holder hereof may from time to
time designate in writing to the Company. Payment shall be credited first to
the accrued interest then due and payable and the remainder applied to
principal.

         2. AUTOMATIC CONVERSION. Notwithstanding the foregoing, if the
Company consummates an equity financing (in one or a series of closings)
after the date of this Note but on or prior to June 30, 1999 resulting in
gross aggregate proceeds to the Company of at least Two Million Dollars
($2,000,000) (an "Equity Financing"), then the unpaid principal amount of the
Note and any accrued but unpaid interest shall be automatically converted
into fully paid and nonassessable shares of the Company's capital stock (the
"New Stock") sold in such financing. The number of shares of New Stock to be
issued upon such automatic conversion shall be equal to the quotient obtained
by dividing (x) the unpaid principal amount of this Note plus any accrued but
unpaid interest by (y) the price per share of the shares of New Stock. Any
New Stock to be issued to the Holder shall have the same rights preferences
and privileges as those applicable to shares issued in the Equity Financing.


                                      1


<PAGE>

         If an Equity Financing is not consummated on or prior to June 30,
1999, then the unpaid principal amount of the Note and any accrued but unpaid
interest shall be automatically converted into fully paid and nonassessable
shares of the Company's Series B Preferred Stock ("SERIES B PREFERRED
STOCK"), which shall have rights, preferences and privileges identical to
those of the Company's Series A Preferred, which shall be as set forth in the
Company's Certificate of Incorporation. The number of shares of Series B
Preferred Stock to be issued upon such automatic conversion shall be equal to
the quotient obtained by dividing (a) the unpaid principal amount of this
Note plus any accrued but unpaid interest by (b) $0.2222 (as appropriately
adjusted for stock splits, stock dividends, combinations and the like).

         3. SUBORDINATION. The indebtedness evidenced by this Note is hereby
expressly subordinated, to the extent and in the manner hereinafter set forth,
in right of payment to the prior payment in full of all the Company's Senior
Indebtedness, as hereinafter defined.

            3.1 SENIOR INDEBTEDNESS. As used in this Note, the term "SENIOR
INDEBTEDNESS" shall mean the principal of and unpaid accrued interest on (i)
indebtedness of the Company or with respect to which the Company is a
guarantor, to banks, insurance companies, lease financing institutions or
other financial institutions regularly engaged in the business of lending
money, which is for money borrowed (or purchase or lease of equipment in the
case of lease financing) by the Company (whether or not secured) in the
ordinary course of business, and (ii) any such indebtedness or any
debentures, notes or other evidence of indebtedness issued in exchange for
such Senior Indebtedness, or any indebtedness arising from the satisfaction
of such Senior Indebtedness by a guarantor.

            3.2 DEFAULT ON SENIOR INDEBTEDNESS. If there re should occur any
receivership, insolvency, assignment for the benefit of creditors,
bankruptcy, reorganization or arrangements with creditors (whether or not
pursuant to bankruptcy or other insolvency laws), sale of all or
substantially all of the assets, dissolution, liquidation or any other
marshaling of the assets and liabilities of the Company, or if this Note
shall be declared due and payable upon the occurrence of an event of default
with respect to any Senior Indebtedness, then (i) no amount shall be paid by
the Company in respect of the principal of or interest on this Note at the
time outstanding, unless and until the principal of and interest on the
Senior Indebtedness then outstanding shall be paid in full, and (ii) no claim
or proof of claim shall be filled with the Company by or on behalf of the
Holder of this Note that shall assert any right to receive any payments in
respect of the principal of and interest on this Note, except subject to the
payment in full of the principal of and interest on all of the Senior
Indebtedness then outstanding. If there occurs an event of default that has
been declared in writing with respect to any Senior Indebtedness, or in the
instrument under which any Senior Indebtedness is outstanding, permitting the
holder of such Senior Indebtedness to accelerate the maturity thereof, then,
unless and until such event of default shall have been cured or waived or
shall have ceased to exist, or all Senior Indebtedness shall have been paid
in full, no payment shall be made in respect of the principal of or interest
on this Note, unless within 90 days after the happening of such event of
default, the maturity of such Senior Indebtedness shall not have been
accelerated.


                                      2

<PAGE>

            3.3 EFFECT OF SUBORDINATION. Subject to the rights, if any, of
the holders of Senior Indebtedness under this Section 3 to receive cash,
securities or other properties otherwise payable or deliverable to the Holder
of this Note, nothing contained in this Section 3 shall impair, as between
the Company and the Holder, the obligation of the Company, subject to the
terms and conditions hereof, to pay to the Holder the principal hereof and
interest hereon as and when the same become due and payable, or shall prevent
the Holder of this Note, upon default hereunder, from exercising all rights,
powers and remedies otherwise provided herein or by applicable law.

            3.4 SUBROGATION. Subject to the payment in full of all Senior
Indebtedness and until this Note shall be paid in full, the Holder shall be
subrogated to the rights of the holders of Senior Indebtedness (to the extent
of payments or distributions previously made to such holders of Senior
Indebtedness pursuant to the provisions of Section 3 above) to receive
payments or distributions of assets of the Company applicable to the Senior
Indebtedness. No such payments or distributions applicable to the Senior
Indebtedness shall, as between the Company and its creditors, other than the
holders of Senior Indebtedness and the Holder, be deemed to be a payment by
the Company to or on account of this Note; and for the purposes of such
subrogation, no payments or distributions to the holders of Senior
Indebtedness to which the Holder would be entitled except for the provisions
of this Section 3 shall, as between the Company and its creditors, other than
the holders of Senior Indebtedness and the Holder, be deemed to be a payment
by the Company to or on account of the Senior Indebtedness.

            3.5 UNDERTAKING. By its acceptance of this Note, the Holder
agrees to execute and deliver such documents as may be reasonably requested
from time to time by the Company or the lender of any Senior Indebtedness in
order to implement the foregoing provisions of this Section 3. The provisions
of this Paragraph 3 shall bind any successors or assignees of Holder and
shall benefit any successors or assigns of Bank, and, if the Company
refinances a portion of the Senior Debt with a new lender, such new lender
shall be deemed a successor of Bank for the purposes of this Paragraph 3.
This Paragraph 3 is solely for the benefit of Holder and Bank and not for the
benefit of the Company or any other party. The provisions of this Paragraph 3
may be amended only by written instrument signed by Holder and Bank. In the
event of any legal action to enforce the rights of a party under this
Paragraph 3, the party prevailing in such action shall be entitled, in
addition to such other relief as may be granted, all reasonable costs and
expenses, including reasonable attorneys' fees, incurred in such action.

         4. MISCELLANEOUS.

            4.1 COSTS. If action is instituted to collect this Note by
Holder, the Company hereby agrees to pay all costs and expenses, including
reasonable attorneys' fees, incurred by Holder in connection with such action.

            4.2 DELAY. No extension of time for payment of any amount
owing hereunder shall affect the liability of the Company for payment of the
indebtedness evidenced hereby. No delay by the Holder or any holder hereof in
exercising any power or right hereunder shall operate as a waiver of any power
or right hereunder.


                                       3

<PAGE>

            4.3 WAIVER AND AMENDMENT. No waiver or modification of the terms
of this Note shall be valid without the written consent of the holders of
over fifty percent (50%) of the indebtedness represented by this Note and all
other Notes issued by the Company pursuant to the Note Agreement; provided,
however, that any such waiver or modification of Paragraph 3 shall require
the written consent of any holder of Senior Indebtedness and provided,
further, that the terms and provisions of this Note shall not be amended in a
manner different than any other Note without the consent of the Holder and of
the holders of over fifty percent (50%) of the indebtedness represented by
all Notes issued by the Company pursuant to the Note Agreement.

            4.4 GOVERNING LAW. This Note shall be governed by and construed
in accordance with the laws of the State of California as applied to
contracts entered into between California residents wholly to be performed in
California.

            4.5 SEVERABILITY. In case any provision contained herein (or part
thereof) shall for any, reason be held to be invalid, illegal, or
unenforceable in any respect, such invalidity, illegality, or other
unenforceability shall not affect any other provision (or the remaining part
of the affected provision) hereof, but this Note shall be construed as if
such invalid, illegal, or unenforceable provision (or part thereof) had never
been contained herein, but only to the extent that such provision is invalid,
illegal, or unenforceable.

            4.6 NOTICE. Any notice or other communication required or
permitted hereunder shall be in writing, and shall be deemed to have been
duly given on the date of service if served personally or by facsimile, or
five days after the date of mailing if mailed, by first class mail,
registered or certified, postage prepaid. Notices shall be addressed as

<PAGE>

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

Where     X = The number of shares of Preferred Stock to be issued to the
              Registered Holder.

          Y = The number of shares of Preferred Stock purchasable
              under this Warrant (at the date of such calculation).

          A = The fair market value of one share of Preferred Stock (at
              the date of such calculation).

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

            (ii) For purposes of this Section 2(c), the fair market value of
the Company's Preferred Stock shall be the price per share which the Company

fair market value of the Company's Preferred Stock shall be equal to the
mid-price of the range of prices set forth in the registration statement
relating to the Initial Public Offering or, if a subsequent amendment thereto
sets forth a different range of prices (other than a "pricing amendment"
setting forth a single, final price) then the mid-price of the range of
prices set forth in such amendment.

        (d) As soon as practicable after the exercise of this Warrant in full
or in part, and in any event within 10 days thereafter, the Company at its
expense will cause to be issued in the name of, and delivered to, the
Registered Holder, or as such Holder (upon payment by such Holder of any
applicable transfer taxes) may direct a certificate or certificates for the
number of shares of Warrant Stock to which such Registered Holder shall
entitled.

        (a) If, after the closing date of the Equity Financing or the date
upon which all of the Notes issued pursuant to the Purchase Agreement are
converted, outstanding shares of the Company's Preferred Stock shall be
subdivided greater number of shares or a dividend in Preferred Stock shall be
paid in respect of Preferred Stock, the Purchase Price in effect immediately
prior to such subdivision or at the record date of such dividend shall
simultaneously with the effectiveness of such subdivision or immediately
after the record date of such dividend be proportionately reduced. If
outstanding shares of Preferred Stock shall be combined into a smaller number
of shares, the Purchase Price in effect immediately prior to such combination
shall, simultaneously with the effectiveness of such combination, be,
proportionately increased. When any adjustment is required to be made in the
Purchase Price, the number of shares of Warrant Stock purchasable upon the
exercise of this Warrant shall be changed to the number determined by
dividing (i) an amount equal to the number of shares issuable upon the
exercise of this Warrant immediately prior to such adjustment, multiplied by
the Purchase Price in effect


                                       3

<PAGE>

immediately prior to such adjustment, by (ii) the Purchase Price in effect
immediately after such adjustment.

        (b) In case of any reclassification or change of the outstanding
securities of the Company or of any reorganization of the Company (or any
other corporation the stock or securities of which are at the time receivable
upon the exercise of this Warrant) or any similar corporate reorganization on
or after the date hereof, then and in each such case the holder of this
Warrant, upon the exercise hereof at any time after the consummation of such
reclassification, change, reorganization, merger or conveyance, shall be
entitled to receive, in lieu of the stock or other securities and property
receivable upon the exercise hereof prior to such consummation, the stock or
other securities or property to which such holder would have been entitled
upon such consummation if such holder had exercised this Warrant immediately
prior thereto, all subject to further adjustment as provided in paragraph
(a); and in each such case, the terms of this Section 2 shall be applicable
to the shares of stock or other securities properly receivable upon the
exercise of this Warrant after such consummation.

        (c) When any adjustment is required to be made in the Purchase Price,
the Company shall promptly mail to the Registered Holder a certificate
setting forth the Purchase Price after such adjustment and setting forth a
brief statement of the facts requiring such adjustment. Such certificate
shall also set forth the kind and amount of stock or other securities or
property into which this Warrant shall be exercisable following the
occurrence of any of the events specified in Section 3(a) or (b) above.

        (d) In order to avoid doubt, it is acknowledged that the holder of
this Warrant shall be entitled to the benefit of all adjustments in the
number of shares of Common Stock of the Company issuable upon conversion of
the Preferred Stock of the Company which occur prior to the exercise of this
Warrant, including without limitation, any increase in the number of shares
of Common Stock issuable upon conversion as a result of a dilutive issuance
of capital stock.

and all rights hereunder are transferable, in whole or in part, upon
surrender of the Warrant with a properly

without limitation, actions, suits, proceedings or investigations pending or
threatened involving the prior employment of any of the Company's employees,
their use in connection with the Company's business of any information or
techniques allegedly proprietary to any of their former employers, or their

agreements of any kind with respect to the patents, trademarks, service
marks, trade names, copyrights, trade secrets, licenses, information,

promote the interests of the Company or that would conflict with the
Company's business as proposed to be conducted. Neither the execution nor
delivery of the Transaction Agreements, nor the carrying on of the Company's
business by the employees of the Company will, to the Company's knowledge,

judgment, order, writ, decree or contract to which it is a party or by which
it is bound, or, to its knowledge, of any provision of any federal or state
statute, rule or regulation applicable to the Company. The execution,
delivery and performance of the Transaction Agreements and the consummation
of the transactions contemplated thereby will not result in any such
violation or be in conflict with or constitute, with or without the passage
of time and giving of notice, either a default under any such provision,
instrument, judgment, order, writ, decree or contract or an 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 operations or any of its assets or
properties.

affiliated therewith) shall be aggregated for the purpose of meeting the
individual minimum dollar amounts of such subsections.

                        (e)   The Company is not a party to and is not bound

their immediate families may own stock in publicly traded companies that may
compete with the Company. No member of the immediate family of any officer of

relating to the environment or occupational health and safety, and to its

property and assets free and clear of all mortgages, liens, loans and
encumbrances, except such encumbrances and liens that arise in the ordinary
course of business and do not materially impair the Company's ownership or
use of such property or assets. With respect to the property and assets it
leases, the Company is in compliance with such leases and, to its knowledge,
holds a valid leasehold interest free of any liens, claims or encumbrances.

the Securities it is purchasing are characterized as "restricted securities"
under the federal securities laws inasmuch as they are being acquired from
the Company in a transaction not involving a public offering and that under
such laws and applicable regulations such securities may be resold without
registration under the Act only in certain limited circumstances. In this
connection, such Investor represents that it is familiar with SEC Rule 144,
as presently in effect, and understands the resale limitations imposed
thereby and by the Act.

                  3.7   FURTHER LIMITATIONS ON DISPOSITION. Without in any
way limiting the representations set forth above, such Investor further
agrees not to make any disposition of all or any portion of the Securities
unless and until the transferee has agreed in writing for the benefit of the
Company to be bound by this Section 3, the Amended Investors' Rights
Agreement and the Amended Voting Agreement provided and to the extent this
Section and such agreements are then applicable, and:

                        (a)   There is then in effect a Registration
Statement under the Act covering such proposed disposition and such
disposition is made in accordance with such Registration Statement; or

                        (b)   Such Investor shall have notified the Company
of the proposed disposition and shall have furnished the Company with a
detailed statement of the circumstances surrounding the proposed disposition,
and (ii) if reasonably requested by the Company, such Investor shall have
furnished the Company with an opinion of counsel, reasonably satisfactory to
the Company that such disposition will not require registration of such
shares under the Act. It is agreed that the Company will not require opinions
of counsel for transactions made pursuant to Rule 144 except in unusual
circumstances.

                        (c)   (i) Notwithstanding the provisions of
paragraphs (a) and (b) above, no such registration statement or opinion of
counsel shall be necessary for (i) a transfer by an Investor that is a
partnership to a partner of such partnership or a retired partner of such
partnership who retires after the date hereof, or to the estate of any such
partner or retired partner, the transfer by gift, will or intestate
succession of any partner to his or her spouse or to

                                       9

<PAGE>

the siblings, lineal descendants or ancestors of such partner or his or her
spouse or (ii) a transfer to an Affiliate (as such term is defined in Rule
12(b)(2) promulgated under the Securities Exchange Act of 1934, as amended,
if the transferee agrees in writing to be subject to the terms hereof to the
same extent as if he or she were an original Investor hereunder.

                  3.8   LEGENDS. It is understood that the certificates
evidencing the Securities may bear one or all of the following legends:

                        (a)   "THESE SECURITIES HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED
FOR SALE, PLEDGED OR HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT
IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF
COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED OR
UNLESS SOLD PURSUANT TO RULE 144 OF SUCH ACT."

                        (b)   "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE
SUBJECT TO CERTAIN RESTRICTIONS SET FORTH IN AN AMENDED AND RESTATED
INVESTORS' RIGHTS AGREEMENT, AN AMENDED AND RESTATED RIGHT OF FIRST REFUSAL
AND CO-SALE AGREEMENT AND AN AMENDED AND RESTATED VOTING AGREEMENT, COPIES OF
WHICH MAY BE OBTAINED BY ANY SHAREHOLDER, UPON REQUEST AND WITHOUT CHARGE, AT
THE PRINCIPAL OFFICES OF THE CORPORATION."

                        (c)   Any legend required by the laws of the State of
California, including any legend required by the California Department of
Corporations and Sections 417 and 418 of the California Corporations Code.

         4.       CALIFORNIA COMMISSIONER OF CORPORATIONS.

                  4.1   CORPORATE SECURITIES LAW. THE SALE OF THE SECURITIES
THAT 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
FOR SUCH SECURITIES PRIOR TO SUCH QUALIFICATION IS UNLAWFUL, UNLESS THE SALE
OF SECURITIES IS EXEMPT FROM QUALIFICATION BY SECTION 25100, 25102 OR 25105
OF THE CALIFORNIA CORPORATIONS CODE. THE RIGHTS OF ALL PARTIES TO THIS
AGREEMENT ARE EXPRESSLY CONDITIONED UPON SUCH QUALIFICATION BEING OBTAINED,
UNLESS THE SALE IS SO EXEMPT.

         5.       COVENANTS OF THE COMPANY.

                  5.1   VESTING. All future options granted by the Company
after the date hereof to management, employees and consultants of the Company
shall vest twenty-five percent (25%) after one year of service, and the
remainder in equal monthly installments over the subsequent forty-eight (48)
months, or in the Company's sole discretion, according to any other vesting
schedule which does not at any given time result in a higher vesting
percentage.

                                       10

<PAGE>

Notwithstanding the foregoing provisions of this Section 5.1, by vote of at

         8.       MISCELLANEOUS.

                  8.1   SURVIVAL OF WARRANTIES. The warranties,
representations and covenants of the Company and Investors contained in or
made pursuant to this Agreement shall survive the execution and delivery of
this Agreement and the Closing for a period of one (1) year from the Closing

matter thereof made by or on behalf of the Investors or the Company.

                  8.2   SUCCESSORS AND ASSIGNS. Except as otherwise provided
herein, the terms and conditions of this Agreement shall inure to the benefit
of and be binding upon the respective successors and assigns of the parties
(including transferees of any Securities). Nothing in this Agreement, express
or implied, is intended to confer upon any party other than the parties
hereto or their respective successors and assigns any rights, remedies,
obligations, or liabilities under or by reason of this Agreement, except as
expressly provided in this Agreement.

                  8.3   GOVERNING LAW. This Agreement shall be governed by
and construed under the laws of the State of California as applied to
agreements among California residents entered into and to be performed
entirely within California.

<PAGE>

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

                  8.5   TITLES AND SUBTITLES. The titles and subtitles used
in this Agreement are used for convenience only and are not to be considered
in construing or interpreting this Agreement.

                  8.6   NOTICES. Unless otherwise provided, any notice
required or permitted under this Agreement shall be given in writing and
shall be deemed effectively given upon personal delivery to the party to be
notified or upon deposit with the United States Postal Service, by registered
or certified mail, postage prepaid and addressed to the party to be notified
at the address indicated for such party on the signature page hereof, or at
such other address as such party may designate by ten (10) days' advance
written notice to the other parties.

                  8.7   FINDER'S FEE. Each party represents that it neither
is nor will be obligated for any finders' fee or commission in connection
with this transaction. Each Investor agrees to indemnify and to hold harmless
the Company from any liability for any commission or compensation in the
nature of a finders' fee (and the costs and expenses of defending against
such liability or asserted liability) for which such Investor or any of its
officers, partners, employees, or representatives is responsible and the
Company agrees to indemnify and hold harmless each Investor from any
liability for any commission or compensation in the nature of a finders' fee
(and the costs and expenses of defending against such liability or asserted
liability) for which the Company or any of its officers, employees or
representatives is responsible.

                  8.8   EXPENSES. Irrespective of whether the Closing is
effected, the Company shall pay all costs and expenses that it incurs with
respect to the negotiation, execution, delivery and performance of this
Agreement. If the Closing is effected, the Company shall reimburse the

total of $5,000, payable at the Closing. If any action at law or in equity is
necessary to enforce or interpret the terms of this Agreement, the prevailing
party shall be entitled to reasonable attorney's fees, costs and necessary
disbursements in addition to any other relief to which such party may be
entitled.

                  8.9   AMENDMENTS AND WAIVERS. Any term of this Agreement
may be amended and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and the holders
of a majority of the Common Stock issued upon conversion of the Series C
Preferred Stock (assuming the conversion of the Series C Preferred Stock).
Any amendment or waiver effected in accordance with this paragraph shall be
binding upon each holder of any securities purchased under this Agreement at
the time outstanding (including securities into which such securities are
convertible), each future holder of all such securities, and the Company.

                  8.10  DISPUTES. If the parties are unable, after good
faith negotiations, which each hereby covenants to undertake, to resolve any
dispute arising between them within fifteen (15) days after notice is given
of such dispute, then the dispute will be referred to arbitration (which the
parties agree is the exclusive means of resolving any such dispute) before
one (1)

                                       13

<PAGE>

arbitrator in Los Angeles County, California, or any other place mutually
agreed upon by the parties hereto, in accordance with the applicable rules
then in effect of the Judicial Arbitration and Mediation Service (the "JAMS
Rules") (or any other form of arbitration mutually acceptable to the
parties). The determination made in accordance with the JAMS rules shall be
delivered in writing to the parties hereto and shall be final, binding and
conclusive on the parties hereto, and the amount of the claim, if any,
determined to exist shall be a valid claim and no further remedy shall be
available to either party with respect to such dispute and judgment may be
entered upon such decision in accordance with applicable law in any court
having jurisdiction thereof. The arbitration award shall include (i) a
provision that the prevailing party in such arbitration recover its costs
relating to the arbitration and reasonable attorneys' fees from the other
party, (ii) the amount of such costs and fees, and (iii) an order that the
losing party pay the fees and expenses of the arbitrator.

                  8.11  SEVERABILITY. If one or more provisions of this
Agreement are held to be unenforceable under applicable law, such provision
shall be excluded from this Agreement and the balance of the Agreement shall
be interpreted as if such provision were so excluded and shall be enforceable
in accordance with its terms.

                  8.12  AGGREGATION OF STOCK. All shares of Series C
Preferred Stock held or acquired by affiliated entities or persons shall be
aggregated together for the purpose of determining the availability of any
rights under this Agreement.

                  8.13  ENTIRE AGREEMENT. This Agreement and the documents
referred to herein constitute the entire agreement among the parties and no
party shall be liable or bound to any other party in any manner by any
warranties, representations, or covenants except as specifically set forth
herein or therein.

                                    set forth in Article 23 of this Lease.

ARTICLE 2 - TERM
- ----------------

         The term of this Lease shall commence on the Commencement Date as set
forth in Article 1.A. of the Basic Lease Provisions, and shall end on the
Expiration Date set forth in Article 1.A. of the Basic Lease Provisions. For
purposes of this Lease, the term "Lease Year" shall mean each consecutive twelve
(12) month period during the Lease term, with the first Lease Year commencing on
the Commencement Date; however, (a) if the Commencement Date falls on a day
other than the first day of a calendar month, the first Lease Year shall end on
the last day of the eleventh (11th) month after the Commencement Date and the
second (2nd) and each succeeding Lease Year shall commence on the first day of
the next calendar month, and (b) the last Lease Year shall end on the Expiration
Date. Notwithstanding anything to the contrary contained herein, if the
substantial completion of the Tenant Improvements to be performed by Landlord
pursuant to the Work Letter Agreement attached hereto as Exhibit "D" has not
occurred on or before August 1, 1999 (the "Deadline Date"), Tenant shall have
the right to terminate this Lease by notifying Landlord in writing of such
election at any time prior to said substantial completion. In the event of any
such termination, neither party shall have any further rights, obligations or
liabilities hereunder from and after the effective date of such termination and
Landlord shall promptly return any monies paid by Tenant, including, without
limitation, the anticipated first month's rent and the security deposit to
Tenant. The Deadline Date shall be extended for any delays in the substantial
completion of the Tenant Improvements caused by a Tenant Delay (defined in the
Work Letter Agreement), force majeure event or governmental delay, provided that
in no event shall any force majeure event or governmental delay extend the
Deadline Date by more than ninety (90) days.

ARTICLE 3 - RENTAL
- ------------------

         (a) BASIC RENTAL. Commencing on the Commencement Date and continuing
throughout the balance of the Term, Tenant agrees to pay to Landlord, at
Landlord's office, or to such other person or at such other place as directed
from time to time by written notice to Tenant from Landlord, the initial monthly
and annual sums as set forth in Article 1.C of the Basic Lease Provisions,
payable in advance on the first day of each calendar month, without demand,
setoff or deduction (except as otherwise specifically provided herein), and in
the event the Commencement Date or the Expiration Date of this Lease occurs
other than on the first day or last day of a calendar month, the rent for such
month shall be prorated. Notwithstanding the foregoing, the first full month's
rent shall be paid to Landlord in accordance with Article 1.J. of the Basic
Lease Provisions.

         (b) INCREASE IN DIRECT COSTS. The term "Base Year" means the calendar
year set forth in Article 1.D. of the Basic Lease Provisions. If, in any
calendar year during the term of this Lease, the Direct Costs (as hereinafter
defined) paid or incurred by Landlord shall be higher than the Direct Costs for
the Base Year, Tenant shall pay an additional sum for such and each subsequent
calendar year equal to the product of Tenant's Proportionate Share (as defined
in Article 1.E of the Basic Lease Provisions) multiplied by such increased
amount of Direct Costs. In the event either the Premises and/or the Project is
expanded or reduced, then Tenant's Proportionate Share shall be appropriately
adjusted, and as to the calendar year in which such change occurs, Tenant's
Proportionate Share for such year shall be determined on the basis of the number
of days during that particular calendar year that such Tenant's proportionate
share was in effect. In the event this Lease shall terminate on any date other
than the last day of a calendar year, the additional sum payable hereunder by
Tenant during the calendar year in which this Lease terminates shall be prorated
on the basis of the relationship which the number of days which have elapsed
from the commencement of said calendar year to and including said date on which
this Lease terminates bears to three hundred sixty-five (365). Any and all
amounts due and payable by Tenant pursuant to Articles 3(b), (c) and (d) hereof
shall be deemed "Additional Rent", and Landlord shall be entitled to exercise
the same rights and remedies upon default in these payments as Landlord is
entitled to exercise with respect to defaults in Monthly Basic Rental payments.

                                -3-
<PAGE>

     (c) DEFINITIONS. As used herein the term "Direct Costs" shall mean the sum
of the following:

                  (i) "Tax Costs", which shall mean any and all real estate
taxes and other similar charges on real property or improvements, assessments,
water and sewer charges, and all other charges assessed, reassessed or levied
upon the Project and appurtenances thereto and the parking or other facilities
thereof, or the real property thereunder (collectively, "Real Property") or
attributable thereto or on the rents, issues, profits or income received or
derived therefrom which are assessed, reassessed or levied by the United States,
the State of California or any local government authority or agency or any
political subdivision thereof, and shall include Landlord's reasonable legal
fees, costs and disbursements incurred in connection with proceedings for
reduction of Tax Costs or any part thereof (but only up to the actual amount of
savings, amortized on a straight-line basis over the Lease Term); provided,
however, if at any time after the date of this Lease the methods of taxation now
prevailing shall be altered so that in lieu of or as a supplement to or a
substitute for the whole or any part of any Tax Costs, there shall be assessed,
reassessed or levied (a) a tax, assessment, reassessment, levy, imposition or
charge wholly or partially as a net income, capital or franchise levy or
otherwise on the rents, issues, profits or income derived therefrom, or (b) a
tax, assessment, reassessment, levy (including, but not limited to, any
municipal, state or federal levy), imposition or charge measured by or based in
whole or in part upon the Real Property and imposed upon Landlord, or (c) a
license fee measured by the rent payable under this Lease, then all such taxes,
assessments, reassessments or levies or the part thereof so measured or based,
shall be deemed to be included in the term "Direct Costs". In addition, when
calculating Tax Costs for the Base Year, special assessments shall only be
deemed included in Tax Costs for the Base Year to the extent that such special
assessments are included in Tax Costs for the applicable subsequent calendar
year during the Term. There shall be included in Tax Costs with respect to any
calendar year only the amount currently payable on any bonds or assessments,
including interest for such calendar year or the current annual installment for
such calendar year, and such sum shall be paid in the maximum number of
installments allowed. Notwithstanding anything to the contrary contained herein,
Tax Costs for the Base Year and all subsequent calendar years shall be
calculated on a fully-assessed basis.

                  (ii) PROPOSITION 13 PROTECTION. Despite any other provision of
this Lease, if any sale, refinancing, or change in ownership of the Project is
consummated and, as a result, all or part of the Project is reassessed
("Reassessment") for real estate tax purposes by the appropriate government
authority under the terms of Proposition 13 (as adopted by the voters of the
State of California in the June 1978 election), the terms of this Paragraph
3(c)(ii) shall apply.

                    I. For purposes of this Paragraph 3(c)(ii), the term "Tax
Increase" shall mean that portion of the Tax Costs, as calculated immediately
following the Reassessment, that is attributable solely to the Reassessment.
Accordingly, a Tax Increase shall not include any portion of the Tax Costs,
as calculated immediately following the Reassessment, that is:

                       (1) Attributable to the initial assessment of the value
of the Project, the base, shell and core of the Project, or the tenant
improvements located in the Project;

                       (2) Attributable to assessments pending immediately
before the Reassessment, but not otherwise excludable, that were conducted
during, and included in, that Reassessment or that were otherwise rendered
unnecessary following the Reassessment;

                       (3) Attributable to the annual inflationary increase
in real estate taxes; or

                       (4) Part of Tax Costs incurred or considered to be
incurred during the applicable Base Year as determined under this Lease.

                                 -4-

          II. Tenant shall not be obligated to pay a portion of the Tax Increase
relating to a Reassessment of the Project in accordance with the following
schedule:

       Months   61 - Expiration Date                           0%

</TABLE>
          III. The amount of Tax Costs that Tenant is not obligated to pay or
shall not be obligated to pay during the Term in connection with a particular
Reassessment under the terms of this Paragraph 3(c)(ii) shall be referred to as
the Proposition 13 Protection Amount. If a Reassessment is reasonably
foreseeable by Landlord and the Proposition 13 Protection Amount attributable to
that Reassessment may be reasonably quantified or estimated for each Lease Year
beginning with the Lease Year in which the Reassessment will occur, the terms of
this Paragraph 3(c)(ii) shall apply to each such Reassessment. On notice to
Tenant, Landlord shall have the right to purchase the entire Proposition 13
Protection Amount relating to the applicable Reassessment (Applicable
Reassessment), at any time during the Term, by paying to Tenant an amount equal
to the Proposition 13 Purchase Price, as defined below, as long as the right of
any successor of Landlord to exercise its right of repurchase under this Lease
shall not apply to any Reassessment that results from the event under which that
successor became Landlord under this Lease. As used in this Lease, the term
"Proposition 13 Purchase Price" shall mean the present value of the Proposition
13 Protection Amount remaining during the Term, as of the date of payment of the
Proposition 13 Purchase Price by Landlord. The present value shall be calculated
by:

               (1) Using the portion of the Proposition 13 Protection Amount
attributable to each remaining Lease Year (as though the portion of that
Proposition 13 Protection Amount benefited Tenant at the end of each Lease Year)
as the amounts to be discounted; and

               (2) Using discount rates for each amount to be discounted
equal to:

                   (A) The average rates of yield for United States Treasury
Obligations with maturity dates as close as reasonably possible to the end of
each Lease Year during which the portions of the Proposition 13 Protection
Amount would have benefited Tenant, using the rates in effect as of
Landlord's exercise of its right to purchase, as set forth in this Paragraph
3(c)(ii); plus

                   (B) two percent (2%) per annum.

On payment of the Proposition 13 Purchase Price, subparagraph (II) of this
Paragraph 3(c)(ii) shall not apply to any Taxes attributable to the Applicable
Reassessment. Because Landlord is estimating the Proposition 13 Purchase Price
because a Reassessment has not yet occurred, an adjustment shall be made when a
Reassessment occurs. If Landlord has underestimated the Proposition 13 Purchase
Price, Landlord shall, on notice to Tenant, credit Tenant's Rent next due with
the amount of that underestimation (and Landlord's successor in interest shall
be bound by any such underestimation). If Landlord has overestimated the
Proposition 13 Purchase Price, Landlord shall, on notice to Tenant, increase
Tenant's Rent next due by the amount of the overestimation.

                  (iii) "Operating Costs", which shall mean all costs and
expenses incurred by Landlord in connection with the maintenance, operation,
replacement, ownership and repair of the Project, the equipment, the
intrabuilding network cable, adjacent walks, malls and landscaped and common
areas and the parking structure, areas and facilities of the Project,
including, but not limited to, salaries, wages, medical, surgical and general
welfare benefits and pension payments, payroll taxes, fringe benefits,
employment taxes, workers' compensation, uniforms and dry cleaning thereof
for all persons who perform duties on a full-time basis (or, if on a
part-time basis, prorated to reflect the percentage of time actually devoted
to the Project) connected with the operation, maintenance and repair of the
Project, its equipment, the intrabuilding network cable and the adjacent
walks and landscaped areas, including janitorial, gardening, security,
parking, operating engineer, elevator, painting, plumbing, electrical,
carpentry, heating, ventilation, air conditioning, window washing, hired
services, a reasonable allowance for depreciation of the cost of acquiring or
the rental expense of personal property used in the maintenance, operation
and repair of the Project, accountant's fees incurred in the preparation of
rent adjustment statements, legal fees (excluding fees incurred in connection
with negotiation and enforcement of leases), real estate tax consulting fees
(but only up to the actual amount of savings, amortized on a straight-line
basis over the Lease Term), personal property taxes on property used in the
maintenance and operation of the Project, capital expenditures incurred to
effect economies of operation (but only to the extent of the actual amount of
savings, amortized on a straight-line basis over the useful life of such
capital improvement) and capital expenditures required by government
regulations, laws, or ordinances, including, but not limited to the American
with Disabilities Act not in effect as of the date of this Lease (amortized
on a straight-line basis over the useful life of such capital improvement);
the cost of all charges for electricity, gas, water and other utilities
furnished to the Project, including any taxes thereon (except to the extent
that such costs are billed directly to any other tenant of the Project); the
cost of all charges for fire and extended coverage, liability and all other
insurance for the Project carried by Landlord (excluding earthquake coverage,
except to the extent earthquake insurance is carried in the Base Year); the
cost of all building and cleaning supplies and materials; the cost of all
charges for cleaning, maintenance and service contracts and other services
with independent contractors and administration fees (except to the extent
that such costs are billed directly to any other tenant of the Project); a
commercially reasonable property management fee (which fee may be imputed if
Landlord has internalized management or otherwise acts as its own property
manager); and license, permit and inspection fees relating to the Project
(excluding such fees paid in connection with the construction of other
tenant's premises). Notwithstanding the foregoing, the following shall not be
included in the calculation of Direct Costs: all costs associated with the
operation of the business of the entity which constitutes "Landlord" (as
distinguished from the costs of building operations) including, but not
limited to, Landlord's general corporate overhead and general administrative
expenses); costs incurred by Landlord in connection with the correction of
defects in design and construction of the Project; leasing commissions;
attorneys' fees and other costs relating to negotiations and disputes with
tenants and prospective tenants; costs relating to improvements, services,
common areas and other items that exclusively or primarily benefit tenants
other than Tenant (and which are not offered to Tenant); depreciation; costs
resulting from violations by Landlord and/or other tenants of laws
(including, but not limited to, laws relating to the storage and handling of
Hazardous Materials), leases and other contracts; interest, amortization,
fees and charges relating to indebtedness; ground rent; employee and other
costs relating to Landlord concessions; rents and other leasing costs for
capital items (other than (i) capital items which are expressly included in
Operating Costs, and (ii) equipment not affixed to the Project that is used
for janitorial or similar services, but only to the extent savings in
Operating Costs are reasonably anticipated as a result of said expenditure);
losses covered by insurance, to the extent of actual proceeds received;
advertising and promotional costs (other than expenses incurred for the
benefit of existing tenants of the Project generally and unrelated to
leasing); costs relating to the correction of law violations existing prior
to the execution of this Lease; franchise taxes, taxes imposed on (or
measured by) Landlord's income and other non-real estate taxes; costs
resulting from additions to the Project following the execution of this Lease
(except to the extent that there is a reasonably proportional corresponding
increase in the rentable square footage in the Project), costs paid or
required to be paid by other tenants (other than as an Operating Cost
pass-through item); overhead or profits paid to subsidiaries or affiliates of

                                     -6-
<PAGE>

Landlord, or to any party as a result of a non-competitive selection process,
for management or other services, supplies or other materials, to the extent
that the costs of such exceed the costs that would have been paid on a
competitive basis; any cost or expense related to the removal, cleaning,
abatement or remediation of Hazardous Materials (as defined below); any costs,
dues or contributions for political, charitable, industry associations or
similar organizations; any acquisition costs for sculptures, paintings or other
objects of fine art or the display of such items; and the cost of any new
categories of services provided subsequent to the Base Year which (I) were not
provided by Landlord during the Base Year as a result of the newly constructed
nature of the Project, and (II) were being provided at comparable buildings
during the Base Year. Operating Costs relating to periods that fall partly
within and partly without any Lease Year and/or the Lease Term shall be
reasonably allocated. In the event, during any calendar year (including the Base
Year), the Project is less than ninety-five percent (95%) occupied at all times,
the Operating Costs shall be adjusted to reflect the Operating Costs of the
Project as though ninety-five percent (95%) were occupied at all times, and the
increase or decrease in the sums owed hereunder shall be based upon such
Operating Costs as so adjusted. Such adjustment shall be made by Landlord by
increasing those costs included in the Operating Costs which according to
industry practice vary based upon the level of occupancy of the Project. Any
warranties in the Base Year and all subsequent calendar years shall be accounted
for as if such service was paid for and provided. Notwithstanding anything to
the contrary contained herein, in no event shall Landlord be permitted to charge
or collect more than the actual Operating Costs incurred in any calendar year.

         (d)      DETERMINATION OF PAYMENT.

                  (i) If for any calendar year ending or commencing within the
Term, Tenant's Proportionate Share of Direct Costs for such calendar year
exceeds Tenant's Proportionate Share of Direct Costs for the Base Year, then
Tenant shall pay to Landlord, in the manner set forth in Sections 3(d)(ii) and
(iii), below, and as additional rent, an amount equal to the excess (the
"Excess").

                  (ii) Landlord shall endeavor to give Tenant a yearly expense
estimate statement (the "Estimate Statement") on or before March 1 of each
calendar year which shall set forth Landlord's reasonable estimate (the
"Estimate") of what the total amount of Direct Costs for the then-current
calendar year shall be and the estimated Excess (the "Estimated Excess") as
calculated by comparing Tenant's Proportionate Share of Direct Costs for such
calendar year, which shall be based upon the Estimate, to Tenant's Proportionate
Share of Direct Costs for the Base Year. The failure of Landlord to timely
furnish the Estimate Statement for any calendar year shall not preclude Landlord
from enforcing its rights to collect any Estimated Excess under this Article 3.
If pursuant to the Estimate Statement an Estimated Excess is calculated for the
then-current calendar year, Tenant shall pay, beginning with its next
installment of Monthly Basic Rental due, a fraction of the Estimated Excess for
the then-current calendar year (reduced by any amounts paid pursuant to the last
sentence of this Section 3(d)(ii)). Such fraction shall have as its numerator
the number of months which have elapsed in such current calendar year to the
month of such payment, both months inclusive, and shall have twelve (12) as its
denominator. Until a new Estimate Statement is furnished, Tenant shall pay
monthly, with the Monthly Basic Rental installments, an amount equal to
one-twelfth (1/12th) of the total Estimated Excess set forth in the previous
Estimate Statement delivered by Landlord to Tenant.

                  (iii) In addition, Landlord shall endeavor to give to Tenant
on or before the first day of April (but in no event later than the first day of
September) following the end of each calendar year, a statement (the
"Statement") which shall state the Direct Costs incurred or accrued for such
preceding calendar year, and which shall indicate the amount, if any, of the
Excess. Upon receipt of the Statement for each calendar year during the Term, if
amounts paid by Tenant as Estimated Excess are less than the actual Excess as
specified on the Statement, Tenant shall pay, with its next installment of
Monthly Basic Rental due, the full amount of the Excess for such calendar year,
less the amounts, if any, paid during such calendar year as Estimated Excess.
If, however, the Statement indicates that amounts paid by Tenant as Estimated
Excess are greater than the actual Excess as specified on the Statement,

                                       -7-
<PAGE>

such overpayment shall be credited against Tenant's next installments of Monthly
Basic Rent. The failure of Landlord to timely furnish the Statement for any
calendar year shall not prejudice Landlord from enforcing its rights under this
Article 3. Even though the Term has expired and Tenant has vacated the Premises,
when the final determination is made of Tenant's Proportionate Share of the
Direct Costs for the calendar year in which this Lease terminates, if an Excess
is present, Tenant shall pay to Landlord within thirty (30) days an amount as
calculated pursuant to the provisions of this Article 3(d), and if Tenant has
overpaid during such calendar year, Landlord shall pay to Tenant within thirty
(30) days the amount of such overpayment. The provisions of this Section
3(d)(iii) shall survive the expiration or earlier termination of the Term.

                  (iv) Within two hundred seventy (270) days after receipt of a
Statement by Tenant ("Review Period"), if Tenant disputes the amount set forth
in the Statement, Tenant's employees or an independent certified public
accountant (which accountant is a member of a nationally or regionally
recognized accounting firm), designated by Tenant, may, after reasonable notice
to Landlord and at reasonable times, inspect Landlord's records at Landlord's
offices, provided that Tenant is not then in default after expiration of all
applicable cure periods and provided further that Tenant and such accountant or
representative shall, and each of them shall use their commercially reasonable
efforts to cause their respective agents and employees to, maintain all
information contained in Landlord's records in strict confidence.
Notwithstanding the foregoing, Tenant shall only have the right to review
Landlord's records one (1) time during any twelve (12) month period. Tenant's
failure to dispute the amounts set forth in any Statement within the Review
Period shall be deemed to be Tenant's approval of such Statement and Tenant,
thereafter, waives the right or ability to dispute the amounts set forth in such
Statement. If after such inspection, but not later than thirty (30) days after
the Review Period, Tenant notifies Landlord in writing that Tenant still
disputes such amounts, a certification as to the proper amount shall be made by
Tenant's certified public accountant, at Tenant's expense. Landlord shall
cooperate in good faith with Tenant and the accountant to show Tenant and the
accountant the information upon which the certification is to be based. However,
if such certification by Tenant's accountant (or pursuant to the terms set forth
below if Landlord disagrees with Tenant's accountant's determination) proves
that the Direct Costs set forth in the Statement were overstated by more than
three percent (3%) then the cost of Tenant's accountant and the cost of such
certification shall be paid for by Landlord. If such certification ultimately
proves that the Direct Costs set forth in the Statement were overstated by less
than 3%, then the cost of Landlord's accountant and the cost of such
certification shall be paid by Tenant. In the event Landlord disagrees with
Tenant's determination, Landlord shall engage an independent certified public
accountant to make a determination of the proper amount. In the event the
determination made by the accountant selected by Landlord and the amount
described in Tenant's certification are within ten percent (10%) of each other,
then the average of the two figures shall be used; if such figures are greater
than ten percent (10%) of each other, the parties shall mutually select a third
certified public accountant to make a determination (whose determination shall
be binding on both parties). Within thirty (30) days following the final
determination of any disputed amounts, the parties shall make such appropriate
payments or reimbursements, as the case may be, to each other, as are determined
to be owing pursuant to this paragraph.

                  (v) If the Project is a part of a multi-building development,
those Direct Costs attributable to such development as a whole (and not
attributable solely to any individual building therein) shall be allocated by
Landlord to the Project and to the other buildings within such development on an
equitable basis.

ARTICLE 4 - SECURITY DEPOSIT
- ----------------------------

         Upon execution hereof, Tenant shall deposit with Landlord the sum set
forth in Article 1.F. of the Basic Lease Provisions as security for the full and
faithful performance of every provision of this Lease to be performed by Tenant.
If Tenant breaches any provision of this Lease, including but not limited to the
payment of rent, Landlord may use all or any part of this security deposit for
the payment of any rent or any other sums in default, or to compensate Landlord
for any other loss or damage which Landlord may suffer by reason of Tenant's

                                       -8-
<PAGE>

default. If any portion of said deposit is so used or applied, Tenant shall,
within five (5) days after written demand therefor, deposit cash with Landlord
in an amount sufficient to restore the security deposit to its original amount.
Tenant agrees that Landlord shall not be required to keep the security deposit
in trust, segregate it or keep it separate from Landlord's general funds, but
Landlord may commingle the security deposit with its general funds, and Tenant
shall not be entitled to interest on such deposit. At the expiration of the
Lease term, and provided there exists no default by Tenant hereunder, the
security deposit, or any balance thereof shall be returned to Tenant (or, at
Tenant's written request, to Tenant's assignee), provided that subsequent to the
expiration of this Lease, Landlord may retain from said security deposit (i) an
amount reasonably estimated by Landlord to cover potential Direct Cost
reconciliation payments due with respect to the calendar year in which this
Lease terminates or expires (such amount so retained shall not, in any event,
exceed ten percent (10%) of estimated Excess payments due from Tenant for such
calendar year through the date of expiration or earlier termination of this
Lease and any amounts so retained and not applied to such reconciliation shall
be returned to Tenant within thirty (30) days after Landlord's delivery of the
Statement for such calendar year), (ii) any and all amounts reasonably estimated
by Landlord to cover the anticipated costs to be incurred by Landlord to remove
any signage provided to Tenant under this Lease and to repair any damage caused
by such removal (in which case any excess amount so retained by Landlord shall
be returned to Tenant within thirty (30) days after such removal and repair),
and (iii) any and all amounts permitted by law or this Article 4. Tenant hereby
waives the provisions of Section 1950.7 of the California Civil Code and all
other provisions of law, now or hereafter in effect, which provide that Landlord
may claim from a security deposit only those sums reasonably necessary to remedy
defaults in the payment of rent, to repair damage caused by Tenant or to clean
the Premises, it being agreed that Landlord may, in addition, claim those sums
specified in this Article 4 above.

         In addition to the cash security deposit referenced in Article 1.F. of
the Basic Lease Provisions, concurrently with the execution of this Lease by
Tenant, Tenant shall deliver to Landlord an additional security deposit in the
form of an irrevocable standby letter of credit in favor of Landlord in an
amount equal to $793,960.00 (the "Letter of Credit"). The Letter of Credit shall
be (i) from Silicon Valley Bank, (ii) in the form and content of that attached
hereto as Exhibit "F" (or on a different form which is reasonably acceptable to
Landlord), and (iii) subject to the conditions stated in this paragraph. The
Letter of Credit shall have a term of at least 12 months and be automatically
renewed (or a reasonably satisfactory replacement Letter of Credit from Silicon
Valley Bank or another bank reasonably acceptable to Landlord shall be in place
in strict accordance with the terms hereof) at least thirty (30) days prior to
expiration of each 12 month period for additional periods of 12 months each
until the 30th day following the expiration of the Term. The Letter of Credit
shall be held by Landlord as additional security for the full and faithful
performance by Tenant of the terms, covenants and conditions of this Lease
during the Term. Provided that Tenant is not in default under this Lease, after
all applicable notice and cure periods, the amount of the Letter of Credit shall
be reduced annually on the anniversary of the Commencement Date by the greater
of (i) 14% of the original amount of the Letter of Credit, or (ii) provided that
Tenant evidences to Landlord's reasonable satisfaction (based upon Landlord's
review of Tenants audited financial statements) that Tenant's business
operations from the Premises returned a net profit to Tenant during the
immediately preceding twelve (12) month period, twenty percent (20%) of the
original amount of the Letter of Credit.

         In addition to the foregoing, (i) if Tenant becomes a publicly traded
company on a nationally recognized stock exchange with a market capitalization
in excess of $50,000,000 for no less than two (2) consecutive months, or (ii) if
Tenant evidences to Landlord's reasonable satisfaction that Tenant has received
at least $50,000,000 in a private equity investment from a third party investor
(either of the events identified in subparagraphs (i) and (ii) to be referred to
as an "LC Reduction Event"), then the outstanding amount of the Letter of Credit
shall be reduced by 50% on or before the date which is three (3) months after
the LC Reduction Event.

         If Tenant breaches any of the terms or conditions of this Lease, beyond
the expiration of all applicable notice and cure periods, or if Tenant has filed
a voluntary petition under the United States Bankruptcy Code, or Tenant's
creditors have filed an involuntary petition under

                                       -9-
<PAGE>

the United States Bankruptcy Code, then Landlord may draw upon all or a portion
of the Letter of Credit for the payment of the required amount of any sum in
default, and for the payment of any amount that Landlord may spend or may become
obligated to spend by reason of Tenant's default, and to compensate Landlord for
any other loss or damage that Landlord suffers by reason of Tenant's default to
the extent Landlord is entitled to compensation therefor pursuant to the terms
of this Lease (any amount of the Letter of Credit which is drawn upon by
Landlord in accordance with the provisions hereof, but is not used or applied in
accordance with the terms of this Lease, shall be deemed a part of the Security
Deposit). The use, application or retention of the Letter of Credit, or any
portion thereof, shall not prevent Landlord from exercising any other rights or
remedies provided under this Lease, it being intended that Landlord shall not be
required to proceed against the Security Deposit, including the Letter of
Credit, and shall not operate as a limitation on any recovery to which Landlord
may otherwise be entitled.

ARTICLE 5 - HOLDING OVER
- ------------------------

         Should Tenant, without Landlord's written consent, hold over after
termination of this Lease, Tenant shall become a tenant from month-to-month,
only upon each and all of the terms herein provided as may be applicable to a
month-to-month tenancy, and any such holding over shall not constitute an
extension of this Lease. During such holding over, Tenant shall pay in advance,
monthly rent at (a) one hundred twenty-five percent (125%) for the first month
of the holdover period and (b) one hundred fifty percent (150%) for each month
thereafter, of the rate in effect for the last month of the term of this Lease,
in addition to, and not in lieu of, all other payments required to be made by
Tenant hereunder, including, but not limited to, Tenant's Proportionate Share of
any Excess. Nothing contained in this Article 5 shall be construed as consent by
Landlord to any holding over of the Premises by Tenant, and Landlord expressly
reserves the right to require Tenant to surrender possession of the Premises to
Landlord as provided in this Lease upon the expiration or earlier termination of
the Term. If Tenant fails to surrender the Premises upon the expiration or
termination of this Lease, Tenant agrees to indemnify, defend and hold Landlord
harmless from all costs after 30 days of holding over, loss, expense or
liability, including without limitation, claims made by any succeeding tenant
and real estate brokers claims and attorneys' fees.

ARTICLE 6 - PERSONAL PROPERTY TAXES
- -----------------------------------

         Tenant shall pay, prior to delinquency, all taxes assessed against or
levied upon trade fixtures, furnishings, equipment and all other personal
property of Tenant located in the Premises. In the event any or all of Tenant's
trade fixtures, furnishings, equipment and other personal property shall be
assessed and taxed with property of Landlord, or if the cost or value of any
leasehold improvements in the Premises exceeds the cost or value of the Tenant
Improvement Allowance (as defined in the Work Letter Agreement attached hereto
as Exhibit "D") and, as a result, real property taxes for the Project are
increased, Tenant shall pay to Landlord its share of such taxes on the later of
(i) thirty (30) days prior to the delinquency date of such taxes, or (ii) twenty
(20) days following Tenant's receipt from Landlord of a statement in writing
setting forth the amount of such taxes applicable to Tenant's property or
improvements above the value of the Tenant Improvement Allowance. Tenant shall
assume and pay to Landlord at the time of paying Basic Rental any excise, sales,
use, rent, occupancy, garage, parking, gross receipts or other taxes (other than
net income taxes) which may be imposed on or on account of letting of the
Premises or the payment of Basic Rental or any other sums due or payable
hereunder, and which Landlord may be required to pay or collect under any law
now in effect or hereafter enacted. Tenant shall pay directly to the party or
entity entitled thereto all business license fees, gross receipts taxes and
similar taxes and impositions which may from time to time be assessed against or
levied upon Tenant, as and when the same become due and before delinquency.
Notwithstanding anything to the contrary contained herein, any sums payable by
Tenant under this Article 6 shall not be included in the computation of "Tax
Costs."

                                  -10-


<PAGE>

ARTICLE 7 - USE
- ---------------

         Tenant shall use and occupy the Premises only for the use set forth in
Article 1.G. of the Basic Lease Provisions and shall not use or occupy the
Premises or permit the same to be used or occupied for any other purpose without
the prior written consent of Landlord, which Landlord consent may be given or
withheld in Landlord's reasonable discretion, and Tenant agrees that it will use
the Premises in such a manner so as not to interfere with or infringe upon the
rights of other tenants in the Project. Tenant shall, at its sole cost and
expense, promptly comply with all laws, statutes, ordinances and governmental
regulations or requirements now in force or which may hereafter be in force
relating to or affecting (i) the condition, use or occupancy of the Premises or
the Project excluding structural changes to the Project or the Premises not
related to Tenant's particular use of the Premises, and (ii) improvements
installed or constructed in the Premises by or for the sole benefit of Tenant
(other than the Tenant Improvements described in the Tenant Work Letter attached
hereto as Exhibit "D"). Tenant shall not do or permit to be done anything which
would invalidate or increase the cost of any fire and extended coverage
insurance policy covering the Project and/or the property located therein, and
Tenant shall comply with all rules, orders, regulations and requirements of any
organization which sets out standards, requirements or recommendations commonly
referred to by major fire insurance underwriters. Tenant shall promptly upon
demand reimburse Landlord for any additional premium charges for any such
insurance policy assessed or increased by reason of Tenant's failure to comply
with the provisions of this Article.

ARTICLE 8 - CONDITION OF PREMISES
- ---------------------------------

         Subject to Landlord's construction of the Tenant Improvements as
provided in Exhibit "D" and any latent defects, Tenant hereby agrees that the
Premises shall be taken "as is", "with all faults", "without any representations
or warranties", except for minor punch-list items, and Tenant hereby agrees and
warrants that it has investigated and inspected the condition of the Premises
and the suitability of same for Tenant's purposes. Tenant acknowledges that
neither Landlord nor any agent nor any employee of Landlord has made any
representations or warranty with respect to the Premises or the Project or with
respect to the suitability of either for the conduct of Tenant's business, and
Tenant expressly warrants and represents that Tenant has relied solely on its
own investigation and inspection of the Premises and the Project in its decision
to enter into this Lease and let the Premises in an "as is" condition. The
Premises shall be initially improved as provided in, and subject to, the Tenant
Work Letter attached hereto as Exhibit "D" and made a part hereof. Tenant hereby
waives Sections 1941 and 1942 of the Civil Code of California or any successor
provision of law.

         Landlord reserves the right from time to time: (i) to install, use,
maintain, repair, replace and relocate for service to the Premises and/or other
parts of the Project pipes, ducts, conduits, wires, appurtenant fixtures, and
mechanical systems, wherever located in the Premises or the Project, (ii) to
alter, close or relocate any facility in the Premises or the Common Areas or
otherwise conduct any of the above activities for the purpose of complying with
a general plan for fire/life safety for the Project or otherwise, and (iii) to
comply with any federal, state or local law, rule or order with respect thereto
or the regulation thereof not currently in effect. Landlord shall provide Tenant
with commercially reasonable prior notice and shall perform any such work with
the least inconvenience to Tenant as reasonably possible, but in no event shall
Tenant be permitted to withhold or reduce Basic Rental or other charges due
hereunder as a result of same, or otherwise make claim against Landlord for
interruption or interference with Tenant's business and/or operations; provided,
however, in the event such interruption or interference materially and adversely
interferes with the operation of Tenant's business in the Premises for more than
five (5) consecutive business days, then the Basic Rental shall be equitably
abated from and after such fifth (5th) business day during the continuance of
such interruption or interference.

                                      -11-

ARTICLE 9 - REPAIRS AND ALTERATIONS
- -----------------------------------

         (a) Landlord shall maintain the structural portions of the Project
including the foundation, floor/ceiling slabs, roof, curtain wall, exterior
glass, columns, beams, shafts, stairs, stairwells, elevator cabs and common
areas and shall also maintain and repair the basic mechanical, electrical,
lifesafety, plumbing, sprinkler systems and heating, ventilating and
air-conditioning systems. Except as expressly provided as Landlord's obligation
in this Article 9, Tenant shall keep the Premises in good condition and repair,
reasonable wear and tear and casualty excepted. All damage or injury to the
Premises or the Project not covered by Landlord's insurance (unless such lack of
coverage results from Landlord's failure to maintain the insurance it is
required to maintain under this Lease) resulting from the act or negligence of
Tenant, its employees, agents or visitors, guests, invitees or licensees or by
the use of the Premises shall be promptly repaired by Tenant, at its sole cost
and expense, to the reasonable satisfaction of Landlord; provided, however, that
for damage to the Project as a result of casualty or for any repairs that may
impact the mechanical, electrical, plumbing, heating, ventilation or air
conditioning systems of the Project, Landlord shall have the right (but not the
obligation) to select the contractor and oversee all such repairs. Landlord may
make any repairs which are not promptly made by Tenant after Tenant's receipt of
written notice and the reasonable opportunity of Tenant to commence making said
repair within five (5) business days from receipt of said written notice, (with
supporting documentation), and charge Tenant for the cost thereof, which cost
shall be paid by Tenant within five (5) days from invoice from Landlord. Tenant
shall be responsible for the design and function of all non-standard
improvements of the Premises installed at Tenant's request. Except as otherwise
set forth in Article 9(b) below, Tenant waives all rights to make repairs at the
expense of Landlord, or to deduct the cost thereof from the rent. Tenant shall
make no alterations, changes or additions in or to the Premises (collectively,
"Alterations") without Landlord's prior written consent, and then only by
contractors or mechanics approved by Landlord in writing and upon the approval
by Landlord in writing of fully detailed and dimensioned plans and
specifications pertaining to the Alterations in question, to be prepared and
submitted by Tenant at its sole cost and expense. Notwithstanding the foregoing,
Tenant may make strictly cosmetic changes to the finish work in the Premises,
not including any changes affecting the Project structure, appearance, or
systems and equipment, provided (i) at least ten (10) days prior written notice
of such changes is provided to Landlord, and (ii) the cost of such changes does
not exceed $30,000 in any one instance or $60,000 over any 12-month period.
Tenant shall at its sole cost and expense obtain all necessary approvals and
permits pertaining to any Alterations approved by Landlord. If Landlord, in
approving any Alterations, specifies a commencement date therefor, Tenant shall
not commence any work with respect to such Alterations prior to such date.
Tenant hereby indemnifies, defends and agrees to hold Landlord free and harmless
from all liens and claims of lien, and all other liability, claims and demands
arising out of any work done or material supplied to the Premises by or at the
request of Tenant in connection with any Alterations. If permitted Alterations
are made, they shall be made at Tenant's sole cost and expense and shall be and
become the property of Landlord, except that Landlord may, by written notice to
Tenant, given concurrently with Landlord's initial consent to the proposed
Alterations, require Tenant at Tenant's expense to remove all partitions,
counters, railings and other Alterations installed by Tenant, and to repair any
damages to the Premises caused by such removal. Any and all costs attributable
to or related to the applicable building codes of the city in which the Project
is located (or any other authority having jurisdiction over the Project) arising
from Tenant's plans, specifications, improvements, alterations or otherwise
shall be paid by Tenant at its sole cost and expense. With regard to repairs,
Alterations or any other work arising from or related to this Article 9 which
Landlord performs on Tenant's behalf, Landlord shall be entitled to receive an
administrative/supervision fee of three percent (3%) of the total costs of said
repairs, Alterations or other work, provided that there shall be no such
supervision fee in those instances where Tenant or its agents or
representatives, rather than Landlord, are performing the requisite repair,
Alteration or other work, and such repair, Alteration or other work does not
affect the structure of the Project or any of the mechanical, electrical, HVAC,
plumbing or fire/life/safety systems of the Project. The construction of initial
improvements to the Premises shall be governed by the terms of the Tenant Work
Letter and not the terms of this Article 9.

<PAGE>

         (b)      TENANT'S RIGHT TO MAKE REPAIRS.

                  (i) TENANT'S ACTIONS. If Tenant provides notice to Landlord of
an event or circumstance which requires the action of Landlord with respect to
an obligation of Landlord under the terms of this Lease (hereinafter, a
"Required Action"), and Landlord fails to provide such action as required by the
terms of this Lease, then Tenant may proceed to take the required action upon
delivery of an additional fifteen (15) days notice to Landlord specifying that
Tenant is taking such required action, and if such action was required under the
terms of Article 9 or 11 of this Lease to be taken by Landlord, then Tenant
shall be entitled to prompt reimbursement by Landlord of Tenant's reasonable
costs and expenses in taking such action. In the event Tenant takes such action
and such work will affect the systems and equipment, structure of the Project or
exterior appearance of the Project, Tenant shall use only those contractors used
by Landlord in the Project for such work unless such contractors are unwilling
or unable to perform such work, in which event Tenant may utilize the services
of any other qualified contractor which normally and regularly performs similar
work in comparable projects.

                  (ii) PAYMENT OF COSTS. If Landlord does not deliver a detailed
written objection to Tenant, within thirty (30) days after receipt of an invoice
by Tenant of its costs of taking action under Section 9(b)(i), above, which
Tenant claims should have been taken by Landlord, and if such invoice from
Tenant sets forth a reasonably particularized breakdown of its costs and
expenses in connection with taking such action on behalf of Landlord, then
Tenant shall be entitled to deduct from the Monthly Basic Rental payable by
Tenant under this Lease the amount set forth in such invoice. If, however,
Landlord delivers to Tenant within thirty (30) days after receipt of Tenant's
invoice, a written objection to the payment of such invoice, setting forth with
reasonable particularity Landlord's reasons for its claim that such action did
not have to be taken by Landlord pursuant to the terms of this Lease or that the
charges are excessive (in which case Landlord shall pay the amount it contends
would not have been excessive), then Tenant shall not be entitled to such
deduction from the Monthly Basic Rental, but as Tenant's sole remedy (except as
set forth in Article 16, below), Tenant may proceed to institute legal
proceedings against Landlord to collect the amount set forth in the subject
invoice. In the event Tenant prevails in such legal proceedings and receives a
judgment against Landlord, then Landlord shall pay such judgment to Tenant
within thirty (30) days of such judgment being entered. If such judgment is not
so paid, then Tenant shall be entitled to deduct from Monthly Basic Rental
payable by Tenant under this Lease in the amount of such judgment together with
interest thereon at the Interest Rate from the date Tenant advanced the funds
until the date of such deduction.

                  (iii) Notwithstanding the foregoing, if there exists an
emergency such that the Premises or a material portion thereof are rendered
untenantable and Tenant's personnel are forced to vacate the Premises or such
material portion thereof and if Tenant gives the Project's management office
written notice (the "Emergency Notice") of Tenant's intention to take action
with respect thereto (the "Necessary Action") and the Necessary Action is also a
Required Action, Tenant may take the Necessary Action if Landlord does not
commence the Necessary Action prior to the end of the business day which is one
(1) day following the day of Landlord's receipt of the Emergency Notice (the
"Emergency Cure Period") and thereafter use its commercially reasonably efforts
and due diligence to complete the Necessary Action as soon as reasonably
practicable. To the extent Tenant is entitled to recover damages from Landlord
by reason of Landlord's failure timely to commence and/or complete the Necessary
Action, Tenant's damages may include, without limitation, the fully documented,
reasonable, out-of-pocket costs incurred, during the period ending on the
substantial completion of the Necessary Action, in any relocation of Tenant's
personnel previously located in such untenantable space which shall have
occurred, including by way of example only, higher rent, brokers' commissions,
fees of consultants and other reasonable costs of moving to other premises. If
Tenant takes any Necessary Action hereunder, Tenant shall use only those
contractors used by Landlord in the Project for such work unless such
contractors are unwilling or unable to perform such work, in which event Tenant
may utilize the services of any other qualified contractor which normally and
regularly performs similar work in comparable projects.

                                      -13-

<PAGE>

ARTICLE 10 - LIENS
- ------------------

         Tenant shall keep the Premises and the Project free from any mechanics'
liens, vendors' liens, or any other liens arising out of any work performed,
materials furnished, or obligations incurred by Tenant, and agrees to defend,
indemnify and hold harmless Landlord from and against any such lien or claim or
action thereon, together with costs of suit and reasonable attorneys' fees
incurred by Landlord in connection with any such claim or action. Before
commencing any work of alteration, addition or improvement to the Premises,
Tenant shall give Landlord at least ten (10) business days' written notice of
the proposed commencement of such work (to afford Landlord an opportunity to
post appropriate notices of non-responsibility). In the event that there shall
be recorded against the Premises or the Project or the Property of which the
Premises is a part any claim or lien arising out of any such work performed,
materials furnished or obligations incurred by Tenant and such claim or lien
shall not be removed or discharged or a bond with a face amount equal to one
hundred fifty percent (150%) of such claim posted within ten (10) business days
of filing, Landlord shall have the right but not the obligation to pay and
discharge said lien without regard to whether such lien shall be lawful or
correct or to require that Tenant deposit with Landlord in cash, lawful money of
the United States, one hundred fifty percent (150%) of the amount of such claim,
which sum may be retained by Landlord until such claim shall have been removed
of record or until judgment shall have been rendered on such claim and such
judgment shall have become final, at which time Landlord shall have the right to
apply such deposit in discharge of the judgment on said claim and any costs,
including attorneys' fees, incurred by Landlord, and shall remit the balance
thereof to Tenant.

ARTICLE 11 - PROJECT SERVICES
- -----------------------------

         (a) Landlord agrees to furnish to the Premises, at a cost to be
included in Operating Costs, from 8:00 a.m. to 6:00 p.m., Mondays through
Fridays, and 9:00 a.m. to 1:00 p.m. on Saturdays, excepting local and national
holidays, air conditioning and heat, all in such reasonable quantities as in the
judgment of Landlord is reasonably necessary for the comfortable occupancy of
the Premises and consistent with similar quality office buildings in the general
vicinity of the Project. In addition, Landlord shall provide electric current
for normal lighting and normal office machines, elevator service and water on
the same floor as the Premises for lavatory and drinking purposes in such
reasonable quantities as in the judgment of Landlord is reasonably necessary for
general, normal office use. Janitorial and maintenance services shall be
furnished five (5) days per week, after regular business hours, excepting local
and national holidays. Tenant shall comply with all rules and regulations which
Landlord may reasonably establish for the proper functioning and protection of
the common area air conditioning, heating, elevator, electrical intrabuilding
network cable and plumbing systems, provided such rules are consistently applied
to all tenants of the Project. Landlord shall not be liable for, and there shall
be no rent abatement as a result of, any stoppage, reduction or interruption of
any such services caused by governmental rules, regulations or ordinances, riot,
strike, labor disputes, breakdowns, accidents, necessary repairs or other cause,
unless such stoppage, reduction or interruption materially and adversely
interferes with Tenant's use of the Premises and continues for a period in
excess of five (5) consecutive business days. Except as specifically provided in
this Article 11, Tenant agrees to pay for all utilities and other services
utilized by Tenant and additional building services furnished to Tenant not
uniformly furnished to all tenants of the Project at the rate generally charged
by Landlord to tenants of the Project.

         (b) Tenant will not, without the prior written consent of Landlord, use
any apparatus or device in the Premises, which will in any way increase the
amount of electricity or water usually furnished or supplied for use of the
Premises as general office space; nor connect any apparatus, machine or device
with water pipes or electric current (except through existing electrical outlets
in the Premises) for the purpose of using electric current or water.

         (c) If Tenant shall require electric current in excess of that which
Landlord is obligated to furnish under Article 11(a) above, Tenant shall first
obtain the written consent of Landlord, which Landlord may refuse in its
reasonable discretion, to the use thereof and

                                      -14-

<PAGE>

Landlord may cause an electric current meter or submeter to be installed in the
Premises to measure the amount of such excess electric current consumed by
Tenant in the Premises. The cost of any such meter and of installation,
maintenance and repair thereof, shall be paid for by Tenant, and Tenant agrees
to pay to Landlord promptly upon demand therefor by Landlord, for all such
excess electric current consumed by any such use as shown by said meter at the
rates charged for such service by the city in which the Project is located or
the local public utility, as the case may be, furnishing the same, plus any
additional expense incurred by Landlord in keeping account of the electric
current so consumed.

         (d) If any lights, machines or equipment (including, but not limited to
computers) are used by Tenant in the Premises which materially affect the
temperature otherwise maintained by the air conditioning system, or generate
substantially more heat in the Premises than would be generated by the building
standard lights and usual office equipment, Landlord shall have the right to
install any machinery and equipment which Landlord reasonably deems necessary to
restore temperature balance, including, but not limited to, modifications to the
standard air conditioning equipment, and the cost thereof, including the cost of
installation and any additional cost of operation and maintenance occasioned
thereby, shall be paid by Tenant to Landlord upon demand by Landlord. Landlord
shall not be liable under any circumstances for loss of or injury to property,
however occurring, through or in connection with, or incidental to, failure to
furnish any of the foregoing.

         (e) If Tenant requires heating, ventilation and/or air conditioning
during times other than the times provided in Article 11(a) above in areas other
than Tenant's Network Room or its customer care area (which shall be separately
controlled and paid for by Tenant pursuant to Article 11(d) above), Tenant shall
give Landlord no less than 24 hours notice prior to the time such services are
required (provided, however, that in the event such systems are remotely
controlled via a telephone system or other Tenant accessible system, then no
such notice shall be required) and Landlord shall provide such services as
requested. Tenant shall pay Landlord's standard charge for such after-hours use
(which charge shall not exceed $25.00 per hour during the Term). Without
limiting the generality of the foregoing. Tenant shall be solely responsible for
all utility costs incurred by Landlord in connection with providing HVAC to a
portion of the Premises from the Supplemental HVAC Unit (as defined in the Work
Letter Agreement attached hereto as Exhibit "D").

         (f) Landlord may impose a reasonable charge for any utilities or
services (other than electric current and heating, ventilation and/or air
conditioning which shall be governed by Articles 11(c) and (e) above) utilized
by Tenant in excess of the amount or type that is typical for general office
use.

         (g) Subject to the terms and conditions of this Lease, Tenant and
Tenant's employees, agents and invitees may access the Premises twenty-four (24)
hours per day, seven (7) days per week, three hundred sixty-five (365) days per
year.

ARTICLE 12 - RIGHTS OF LANDLORD
- -------------------------------

         Upon not less than twenty-four (24) hours prior notice (except in cases
of emergency and for ordinary scheduled cleaning) Landlord and its agents shall
have the right to enter the Premises at all reasonable times for the purpose of
cleaning the Premises, examining or inspecting the same, serving or posting and
keeping posted thereon notices as provided by law, or which Landlord deems
necessary for the protection of Landlord or the Property, showing the same to
prospective tenants (but only during the last six (6) months of the Term),
lenders or purchasers of the Project, in the case of an emergency, and for
making such alterations, repairs, improvements or additions to the Premises or
to the Project as Landlord may deem reasonably necessary or desirable. If Tenant
shall not be personally present to open and permit an entry into the Premises at
any time when such an entry by Landlord is necessary or permitted hereunder,
Landlord may enter by means of a master key or may enter forcibly, only in the
case of an emergency, without liability to Tenant except for any failure to
exercise due care for Tenant's property, and without affecting this Lease.

ARTICLE 13 - INDEMNITY; EXEMPTION OF LANDLORD FROM LIABILITY
- ------------------------------------------------------------

         (a) INDEMNITY BY TENANT. Tenant shall indemnify, defend and hold
Landlord harmless from and against any and all claims arising from Tenant's use
of the Premises or the Project or from the conduct of its business or from any
activity, work or thing which may be permitted or suffered by Tenant in or about
the Premises or the Project and shall further indemnify, defend and hold
Landlord harmless from and against any and all claims arising from any breach or
default in the performance of any obligation on Tenant's part to be performed
under this Lease or arising from any negligence of Tenant or any of its agents,
contractors, employees or invitees, patrons, customers or members in or about
the Project and from any and all costs, attorneys' fees, expenses and
liabilities incurred in the defense of any claim or any action or proceeding
brought thereon, including negotiations in connection therewith. Tenant hereby
assumes all risk of damage to property or injury to persons in or about the
Premises from any cause, and Tenant hereby waives all claims in respect thereof
against Landlord, excepting where the damage is caused by the negligence or
willful misconduct of Landlord.

         (b) INDEMNITY BY LANDLORD. Landlord shall indemnify, defend and hold
Tenant harmless from and against any and all claims arising from any negligence
of Landlord or any of its agents, contractors, employees or invitees, patrons,
customers or members in or about the Project and from any and all costs,
attorneys' fees, expenses and liabilities incurred in the defense of any claim
or any action or proceeding brought thereon, including negotiations in
connection therewith.

         (c) EXEMPTION OF LANDLORD FROM LIABILITY. Landlord shall not be liable
for injury to Tenant's business, or loss of income therefrom, or for damage that
may be sustained by the person, goods, wares, merchandise or property of Tenant,
its employees, invitees, customers, agents, or contractors, or any other person
in, on or about the Premises directly or indirectly caused by or resulting from
fire, steam, electricity, gas, water, or rain which may leak or flow from or
into any part of the Premises, or from the breakage, leakage, obstruction or
other defects of the pipes, sprinklers, wires, appliances, plumbing, air
conditioning, light fixtures, or mechanical or electrical systems or from
intrabuilding network cable, whether such damage or injury results from
conditions arising upon the Premises or upon other portions of the Project or
from other sources or places and regardless of whether the cause of such damage
or injury or the means or repairing the same is inaccessible to Tenant, except
in connection with damage or injury resulting from the negligence or willful
misconduct of Landlord, or its authorized agents. Landlord shall not be liable
to Tenant for any damages arising from any act or neglect of any other tenant of
the Project.

                  Tenant acknowledges that Landlord's election to provide
mechanical surveillance or to post security personnel in the Project is solely
within Landlord's discretion; Landlord shall have no liability in connection
with the decision whether or not to provide such services, and Tenant hereby
waives all claims based thereon. Landlord shall not be liable for losses due to
theft, vandalism, or like causes.

ARTICLE 14 - INSURANCE
- ----------------------

         (a) TENANT'S INSURANCE. Tenant, shall at all times during the term of
this Lease, and at its own cost and expense, procure and continue in force the
following insurance coverage: (i) Commercial General Liability Insurance with a
combined single limit for bodily injury and property damages of not less than
Two Million Dollars ($2,000,000) per occurrence and Three Million Dollars
($3,000,000) in the annual aggregate, including products liability coverage if
applicable, covering the insuring provisions of this Lease and the performance
of Tenant of the indemnity and exemption of Landlord from liability agreements
set forth in Article 13 hereof; (ii) a policy of standard fire, extended
coverage and special extended coverage insurance (all risks), including a
vandalism and malicious mischief endorsement, sprinkler leakage coverage and
earthquake sprinkler leakage, where sprinklers are provided, in an amount equal
to the full replacement value new without deduction for depreciation of all (A)
Alterations, fixtures and other improvements in the Premises which are the
property of

                                      -16-

<PAGE>

Tenant during the term hereof (but specifically excluding the initial Tenant
Improvements), and (B) trade fixtures, furniture, equipment and other personal
property installed by or at the expense of Tenant; and (iii) Workers'
Compensation coverage as required by law. Tenant shall carry and maintain during
the entire Lease term (including any option periods, if applicable), at Tenant's
sole cost and expense, increased amounts of the insurance required to be carried
by Tenant pursuant to this Article 14, and such other reasonable types of
insurance coverage and in such reasonable amounts covering the Premises and
Tenant's operations therein, as may be reasonably required by Landlord, to the
extent such insurance is customarily required by landlords of office buildings
comparable to the Project.

         (b) FORM OF POLICIES. The aforementioned minimum limits of policies
and Tenant's procurement and maintenance thereof shall in no event limit the
liability of Tenant hereunder. The Commercial General Liability Insurance policy
shall name Landlord, Landlord's property manager, Landlord's lender(s) and such
other persons or firms as Landlord reasonably specifies from time to time, as
additional insureds with an appropriate endorsement to the policy(s). All such
insurance policies carried by Tenant shall be with companies having a rating of
not less than A-VIII in Best's Insurance Guide. Tenant shall furnish to
Landlord, from the insurance companies, or cause the insurance companies to
furnish, certificates of coverage. Tenant shall have the right to carry
reasonable deductible amounts under all insurance policies required to be
carried by Tenant. No such policy shall be cancelable or subject to reduction of
coverage or other modification or cancellation except after thirty (30) days'
prior written notice to Landlord by the insurer. All such policies shall be
endorsed to agree that Tenant's policy is primary and that any insurance covered
by Landlord is excess and not contributing with any Tenant insurance requirement
hereunder. Tenant shall, at least twenty (20) days prior to the expiration of
such policies, furnish Landlord with renewals or binders. Tenant agrees that if
Tenant does not take out and maintain such insurance or furnish Landlord with
renewals or binders, Landlord may (but shall not be required to) procure said
insurance on Tenant's behalf and charge Tenant the cost thereof, which amount
shall be payable by Tenant upon demand with interest (at the rate set forth in
Section 20(e) below) from the date such sums are extended. Tenant shall have the
right to provide such insurance coverage, pursuant to blanket policies obtained
by Tenant, provided such blanket policies expressly afford coverage to the
Premises and to Tenant as required by this Lease.

         (c) LANDLORD'S INSURANCE. Landlord shall, as a cost to be included in
Operating Costs, procure and maintain at all times during the term of this
Lease, a policy or policies of insurance covering loss or damage to the Project
in the amount of the full replacement costs without deduction for depreciation
thereof (exclusive of Tenant's trade fixtures, inventory, personal property and
equipment), providing protection against all perils included within the
classification of fire and extended coverage, vandalism coverage, and malicious
mischief, sprinkler leakage, water damage, and special extended coverage on
buildings. Additionally, Landlord may (but shall not be required to) carry: (i)
bodily injury and property damage liability insurance and/or excess liability
coverage insurance; and (ii) rental income insurance (for not more than twelve
(12) months) at its election or if required by its lender from time to time
during the term hereof, in such amounts and with such limits as Landlord or its
lender may deem appropriate. The costs of such insurance shall be included in
Operating Costs (subject to the gross-up provisions of Article 3 above).
Landlord's policies of insurance shall be reasonably comparable to insurance
being carried by prudent landlords of commercial office properties in the
general area surrounding the Project.

         (d) WAIVER OF SUBROGATION. Landlord and Tenant shall each obtain a
waiver of subrogation from its insurer(s) with respect to any policy of
insurance required under Section 14(a) or Section 14(c). If either party shall
fail to obtain a waiver of subrogation as required hereunder, such party shall
indemnify, defend and save the other party harmless from and against any and all
claims, demands, actions, suits, losses, damages, costs, expenses and
liabilities attributable to such failure. Tenant hereby waives any right that
Tenant may have against Landlord and Landlord hereby waives any right that
Landlord may have against Tenant as a result of any loss or damage to the extent
such loss or damage is paid by insurance under such policies.

                                      -17-

<PAGE>

         (e) COMPLIANCE WITH LAW. Tenant agrees that it will not, at any time,
during the term of this Lease, carry any stock of goods or do anything in or
about the Premises which will in any way tend to increase the insurance rates
upon the Project. Tenant agrees to pay Landlord forthwith upon demand the amount
of any increase in premiums for insurance against loss by fire that may be
charged during the term of this Lease on the amount of insurance to be carried
by Landlord on the Project resulting from the foregoing, or from Tenant doing
any act in or about said Premises which does so increase the insurance rates,
whether or not Landlord shall have consented to such act on the part of Tenant.
If Tenant installs upon the Premises any electrical equipment which constitutes
an overload of electrical lines of the Premises, Tenant shall, at its own cost
and expense in accordance with all other Lease provisions, and subject to the
provisions of Articles 9, 10 and 11 hereof, make whatever changes are necessary
to comply with requirements of the insurance underwriters and any governmental
authority having jurisdiction thereover, but nothing herein contained shall be
deemed to constitute Landlord's consent to such overloading. Tenant shall, at
its own expense, comply with all requirements of the insurance authority having
jurisdiction over the Project necessary for the maintenance of reasonable fire
and extended coverage insurance for the Premises, including, without limitation
thereto, the installation of fire extinguishers or an automatic dry chemical
extinguishing system.

ARTICLE 15 - ASSIGNMENT AND SUBLETTING
- --------------------------------------

         Tenant shall have no power to, either voluntarily, involuntarily, by
operation of law or otherwise, sell, assign, transfer or hypothecate this Lease,
or sublet the Premises or any part thereof, or permit the Premises or any part
thereof to be used or occupied by anyone other than Tenant or Tenant's employees
without the prior written consent of Landlord which shall not be unreasonably
withheld or delayed. If Tenant is a corporation, unincorporated association,
partnership or limited liability company, the sale, assignment, transfer or
hypothecation of any class of stock or other ownership interest in such
corporation, association, partnership or limited liability company in excess of
fifty percent (50%) in the aggregate shall be deemed an assignment within the
meaning and provisions of this Article 15. Notwithstanding the above, Tenant
shall have the right to assign this Lease or sublet all or a portion of the
Premises to, WITHOUT LANDLORD'S CONSENT, any of the following (each a "Tenant
Affiliate"): (1) any corporation which controls, is controlled by or under
common control with Tenant, (2) any corporation resulting from the merger or
consolidation of Tenant, or (3) any person or entity which acquires all of the
assets of Tenant as a going concern of the business that is being conducted on
the Premises, provided, however, that (i) said Tenant Affiliate assumes in full
the obligations of Tenant under the Lease, and (ii) the net worth of said Tenant
Affiliate is no less than that of Tenant immediately prior to such transfer. The
term "control" or "controlled" as used herein shall mean the ownership, directly
or indirectly, of at least fifty percent (50%) of the voting securities of, or
possession of the right to vote, in the ordinary direction of its affairs, of at
least 50% of the voting interest in, an entity. Tenant may transfer its interest
pursuant to this Lease only upon the following express conditions, which
conditions are agreed by Landlord and Tenant to be reasonable:

         (a) That the proposed transferee shall be subject to the prior written
consent of Landlord, which consent will not be unreasonably withheld but,
without limiting the generality of the foregoing, it shall be reasonable for
Landlord to deny such consent if:

                  (i) The use to be made of the Premises by the proposed
transferee is (a) not generally consistent with the character and nature of all
other tenancies in the Project, or (b) a use which conflicts with any so-called
"exclusive" then in favor of, or for any use which is the same as that stated in
any percentage rent lease to, another tenant of the Project, or (c) a use which
would be prohibited by any other portion of this Lease (including, but not
limited to, any rules and regulations then in effect);

                  (ii) The financial responsibility of the proposed transferee
is not at least equal to those which were possessed by Tenant as of the date of
execution of this Lease;

                                      -18-

<PAGE>

                  (iii) The proposed transferee is either a governmental agency
or instrumentality thereof; or

                  (iv) Either the proposed transferee or any person or entity
which directly or indirectly controls, is controlled by or is under common
control with the proposed transferee (A) occupies space in the Project at the
time of the request for consent, or (B) is negotiating with Landlord or has
negotiated with Landlord during the six (6) month period immediately preceding
the date of the proposed transfer, to lease space in the Project.

         (b) Whether or not Landlord consents to any such transfer, Tenant shall
pay to Landlord Landlord's then standard processing fee and reasonable
attorneys' fees incurred in connection with the proposed transfer up to the
aggregate sum of One Thousand Dollars ($1,000.00);

         (c) That the proposed transferee shall execute an agreement pursuant to
which it shall agree to perform faithfully and be bound by all of the terms,
covenants, conditions, provisions and agreements of this Lease applicable to
that portion of the Premises so transferred; and

         (d) That an executed duplicate original of said assignment and
assumption agreement or other transfer on a form reasonably approved by
Landlord, shall be delivered to Landlord within five (5) days after the
execution thereof, and that such transfer shall not be binding upon Landlord
until the delivery thereof to Landlord and the execution and delivery of
Landlord's consent thereto. Except for any subleasing, assignment or other
transfer of all of Tenant's interest in this Lease or the Premises (hereinafter
referred to as a "Transfer") to a Tenant Affiliate, it shall be a condition to
Landlord's consent to any Transfer that (i) upon Landlord's consent to any
Transfer, Tenant shall pay and continue to pay fifty percent (50%) of any
"Transfer Premium" (defined below), received by Tenant from the transferee after
payment to Tenant of all costs and expenses paid by Tenant in connection with
said Transfer, including, without limitation, leasing commissions and attorneys'
fees directly relating to the assignment of this Lease; (ii) any sublessee of
part or all of Tenant's interest in the Premises shall agree that in the event
Landlord gives such sublessee notice that Tenant is in default under this Lease,
such sublessee shall thereafter make all sublease or other payments directly to
Landlord, which will be received by Landlord without any liability whether to
honor the sublease or otherwise (except to credit such payments against sums due
under this Lease), and any sublessee shall agree to attorn to Landlord or its
successors and assigns at their request should this Lease be terminated for any
reason, except that in no event shall Landlord or its successors or assigns be
obligated to accept such attornment; (iii) any such Transfer and consent shall
be effected on forms reasonably satisfactory to Landlord and/or its legal
counsel; (iv) Landlord may require that Tenant not then be in default hereunder
in any respect (after applicable notice and cure period); and (v) Tenant or the
proposed subtenant or assignee (collectively, "Transferee") shall agree to pay
Landlord, upon demand, as additional rent, a sum equal to the additional costs,
if any, incurred by Landlord for maintenance and repair as a result of any
change in the nature of occupancy caused by such subletting or assignment.
"Transfer Premium" shall mean all rent, additional rent or other consideration
paid by a Transferee in connection with a Transfer in excess of the rent and
Additional Rent payable by Tenant under this Lease during the term of the
Transfer and if such Transfer is less than all of the Premises, the Transfer
Premium shall be calculated on a rentable square foot basis. "Transfer Premium"
shall also include, but not be limited to, key money, bonus money or other cash
consideration paid by a transferee to Tenant in connection with such Transfer,
and any payment in excess of fair market value for services rendered by Tenant
to the Transferee and any payment in excess of fair market value for assets,
fixtures, inventory, equipment, or furniture transferred by Tenant to the
Transferee in connection with such Transfer. Any sale, assignment,
hypothecation, transfer or subletting of this Lease which is not in compliance
with the provisions of this Article 15 shall be void and shall, at the option of
Landlord, terminate this Lease. In no event shall the consent by Landlord to an
assignment or subletting be construed as relieving Tenant, any assignee, or
sublessee from obtaining the express written consent of Landlord to any further
assignment or subletting, or as releasing Tenant from any

                                      -19-

<PAGE>

liability or obligation hereunder whether or not then accrued and Tenant shall
continue to be fully liable therefor. No collection or acceptance of rent by
Landlord from any person other than Tenant shall be deemed a waiver of any
provision of this Article 15 or the acceptance of any assignee or subtenant
hereunder, or a release of Tenant (or of any successor of Tenant or any
subtenant). Notwithstanding anything to the contrary in this Lease, if Tenant or
any proposed Transferee claims that Landlord has unreasonably withheld or
delayed its consent under this Article 15 or otherwise has breached or acted
unreasonably under this Article 15, their sole remedies shall be a declaratory
judgment and an injunction for the relief sought, including an action for
monetary damages, and Tenant hereby waives all other remedies, including,
without limitation, any right at law or equity to terminate this Lease, on its
own behalf and, to the extent permitted under all applicable laws, on behalf of
the proposed Transferee.

         Notwithstanding anything to the contrary contained in this
Article 15, Landlord shall have the option by giving written notice to Tenant
within fifteen (15) days after Landlord's receipt of a request for consent to a
proposed Transfer, to terminate this Lease as to the portion of the Premises
which is the subject of the Transfer. If this Lease is so terminated with
respect to less than the entire Premises, the Basic Rental and Tenant's
Proportionate Share shall be prorated based on the number of rentable square
feet retained by Tenant as compared to the total number of rentable square feet
contained in the original Premises, and this Lease as so amended shall continue
thereafter in full force and effect, and upon the request of either party, the
parties shall execute written confirmation of the same. Notwithstanding the
above, Tenant shall have the right to rescind Landlord's notice of termination
by withdrawing Tenant's request for Landlord's consent within three (3) days of
receiving Landlord's notice of termination, and in such event this Lease shall
continue in full force and effect. The provisions of this paragraph SHALL NOT
AFFECT A TRANSFER TO a Tenant Affiliate.

ARTICLE 16 - DAMAGE OR DESTRUCTION
- ----------------------------------

         If the Project is damaged by fire or other insured casualty and the
insurance proceeds have been made available therefor by the holder or holders of
any mortgages or deeds of trust covering the Premises or the Project, the damage
shall be repaired by Landlord to the extent such insurance proceeds are
available therefor and provided such repairs can, in Landlord's reasonable
opinion, be completed within 240 days after the necessity for repairs as a
result of such damage becomes known to Landlord without the payment of overtime
or other premiums. Until such repairs are completed, rent shall be abated in
proportion to the part of the Premises which is unusable by Tenant in the
conduct of its business (but there shall be no abatement of rent by reason of
any portion of the Premises being unusable for a period equal to one (1) day or
less). However, if the damage is due to the negligence or willful misconduct of
Tenant, its employees or agents, there shall be no abatement of rent, unless and
to the extent Landlord receives rental income insurance proceeds. Upon the
occurrence of any damage to the Premises, Tenant shall assign to Landlord (or to
any party designated by Landlord) all insurance proceeds payable to Tenant under
Section 14(a)(ii)(A) above; provided, however, that if the cost of repair of
improvements within the Premises by Landlord exceeds the amount of insurance
proceeds received by Landlord from Tenant's insurance carrier, as so assigned by
Tenant, such excess costs shall be paid by Tenant to Landlord prior to
Landlord's repair of such damage. If repairs cannot, in Landlord's opinion, be
completed within 240 days after the necessity for repairs as a result of such
damage becomes known to Landlord without the payment of overtime or other
premiums, either Landlord or Tenant may elect to terminate this Lease by
notifying the other party in writing of such termination within sixty (60) days
after Landlord notifies Tenant of its determination that such repair cannot be
made within the 240-day period, such notice to include a termination date which
is sixty (60) days after the date of such notice (without affecting Tenant's
rights, if any, to abate rent). If neither Landlord nor Tenant elects to
terminate this Lease pursuant to the preceding sentence, Landlord shall make
such repairs in a reasonable time and in such event this Lease shall continue in
effect and the rent shall be abated, if at all, in the manner provided in this
Article 16. In addition, Landlord may elect to terminate this Lease if the
Project shall be damaged by fire or other casualty or cause, whether or not the
Premises are affected, and the damage is not fully covered, except for
deductible amounts, by Landlord's insurance policies. Finally, if the Premises
or the

                                      -20-

<PAGE>

Project is damaged to any substantial extent during the last eighteen (18)
months of the Term, then notwithstanding anything contained in this Article 16
to the contrary, either Tenant or Landlord shall have the option to terminate
this Lease by giving written notice to the other party of the exercise of such
option within sixty (60) days after Landlord learns of the necessity for repairs
as the result of such damage. A total destruction of the Project shall
automatically terminate this Lease. Except as provided in this Article 16, there
shall be no abatement of rent and no liability of Landlord by reason of any
injury to or interference with Tenant's business or property arising from such
damage or destruction or the making of any repairs, alterations or improvements
in or to any portion of the Project or the Premises or in or to fixtures,
appurtenances and equipment therein. Tenant understands that Landlord will not
carry insurance of any kind on Tenant's furniture, furnishings, trade fixtures
or equipment, and that Landlord shall not be obligated to repair any damage
thereto or replace the same. Except for proceeds relating to Tenant's furniture,
furnishings, trade fixtures and equipment, Tenant acknowledges that Tenant shall
have no right to any proceeds of insurance relating to property damage. With
respect to any damage which Landlord is obligated to repair or elects to repair,
Tenant, as a material inducement to Landlord entering into this Lease,
irrevocably waives and releases its rights under the provisions of Sections 1932
and 1933 of the California Civil Code.

ARTICLE 17 - SUBORDINATION
- --------------------------

         This Lease is subject and subordinate to all ground or underlying
leases, mortgages and deeds of trust of record as of the date of this Lease
which affect the Property or the Project, including all renewals, modifications,
consolidations, replacements and extensions thereof; provided, however, if the
lessor under any such lease or the holder or holders of any such mortgage or
deed of trust shall advise Landlord that they desire or require this Lease to be
prior and superior thereto, upon written request of Landlord to Tenant, Tenant
agrees to promptly execute, acknowledge and deliver any and all documents or
instruments which Landlord or such lessor, holder or holders deem necessary or
desirable for purposes thereof. Landlord shall have the right to cause this
Lease to be and become and remain subject and subordinate to any and all ground
or underlying leases, mortgages or deeds of trust which may hereafter be
executed covering the Premises, the Project or the property or any renewals,
modifications, consolidations, replacements or extensions thereof, for the full
amount of all advances made or to be made thereunder and without regard to the
time or character of such advances, together with interest thereon and subject
to all the terms and provisions thereof; provided, however, that Landlord
obtains from the lender or other party in question a written undertaking in
favor of Tenant to the effect that such lender or other party will not disturb
Tenant's right of possession under this Lease if Tenant is not then or
thereafter in breach of any covenant or provision of this Lease. Tenant agrees,
within twenty (20) days after Landlord's written request therefor, to execute,
acknowledge and deliver upon request any and all documents or instruments
reasonably requested by Landlord or reasonably necessary or proper to assure the
subordination of this Lease to any such mortgages, deed of trust, or leasehold
estates; provided that no such document shall otherwise alter any of the terms
or provisions hereof. Tenant agrees that in the event any proceedings are
brought for the foreclosure of any mortgage or deed of trust or any deed in lieu
thereof, to attorn to the purchaser or any successors thereto upon any such
foreclosure sale or deed in lieu thereof as so requested to do so by such
purchaser and to recognize such purchaser as the lessor under this Lease so long
as such purchaser or successor agrees not to disturb Tenant's right of
possession hereunder except pursuant to the terms of this Lease. Tenant shall,
within ten (10) days after request execute such further instruments or
assurances as such purchaser may reasonably deem necessary to evidence or
confirm such attornment. Concurrently with its delivery to Landlord, Tenant
agrees to provide copies of any notices of Landlord's default under this Lease
to any mortgagee or deed of trust beneficiary whose address has been provided to
Tenant and Tenant shall provide such mortgagee or deed of trust beneficiary the
right to cure any such default on behalf of Landlord within the time periods set
forth in this Lease. Tenant waives the provisions of any current or future
statute, rule or law which may give or purport to give Tenant any right or
election to terminate or otherwise adversely affect this Lease and the
obligations of the Tenant hereunder in the event of any foreclosure proceeding
or sale.

                                      -21-

ARTICLE 18 - EMINENT DOMAIN
- ---------------------------

         If the whole of the Premises or the Project or so much thereof as to
render the balance unusable by Tenant shall be taken under power of eminent
domain, or is sold, transferred or conveyed in lieu thereof, this Lease shall
automatically terminate as of the date of such condemnation, or as of the date
possession is taken by the condemning authority, at either Landlord or Tenant's
option. No award for any partial or entire taking shall be apportioned, and
Tenant hereby assigns to Landlord any award which may be made in such taking or
condemnation, together with any and all rights of Tenant now or hereafter
arising in or to the same or any part thereof; provided, however, that nothing
contained herein shall be deemed to give Landlord any interest in or to require
Tenant to assign to Landlord any award made to Tenant for the taking of personal
property and trade fixtures belonging to Tenant and removable by Tenant at the
expiration of the term hereof as provided hereunder, for relocation costs, for
the interruption of, or damage to, Tenant's business and goodwill, or any other
amount in addition to the foregoing which does not reduce the amount of the
award payable to Landlord. In the event of a partial taking described in this
Article 18, or a sale, transfer or conveyance in lieu thereof which does not
result in a termination of this Lease, the rent shall be apportioned according
to the ratio that the part of the Premises remaining useable by Tenant bears to
the total area of the Premises and Landlord shall restore the Premises as close
as reasonably practicable to its prior condition. Tenant hereby waives any and
all rights it might otherwise have pursuant to Section 1265.130 of the
California Code of Civil Procedure.

ARTICLE 19 - DEFAULT
- --------------------

         Each of the following acts or omissions of Tenant or of any guarantor
of Tenant's performance hereunder, or occurrences, shall constitute an "Event of
Default":

         (a) Failure or refusal to pay Basic Rental, Additional Rent or any
other amount to be paid by Tenant to Landlord hereunder within five (5) calendar
days after written notice that the same is due or payable hereunder; said five
(5) day period shall be in lieu of, and not in addition to, the notice
requirements of Section 1161 of the California Code of Civil Procedure or any
similar or successor law;

         (b) Except as set forth in Subparagraphs (a) above and (c) through and
including (g) below, failure to perform or observe any other covenant or
condition of this Lease to be performed or observed within thirty (30) days
following written notice to Tenant of such failure; provided, however, that if
such failure cannot reasonably be cured within said thirty-day period, then so
long as Tenant commences to cure within said thirty-day period and diligently
pursues such cure to completion, then the same shall not be an Event of Default.
Such thirty (30) day notice shall be in lieu of, and not in addition to, any law
required under Section 1161 of the California Code of Civil Procedure or any
similar or successor law;

         (c) The taking in execution or by similar process or law (other than
by eminent domain) of the estate hereby created;

         (d) The filing by Tenant or any guarantor hereunder in any court
pursuant to any statute of a petition in bankruptcy or insolvency or for
reorganization or arrangement for the appointment of a receiver of all or a
portion of Tenant's property; the filing against Tenant or any guarantor
hereunder of any such petition, or the commencement of a proceeding for the
appointment of a trustee, receiver or liquidator for Tenant, or for any
guarantor hereunder, or of any of the property of either, or a proceeding by any
governmental authority for the dissolution or liquidation of Tenant or any
guarantor hereunder, if such proceeding shall not be dismissed or trusteeship
discontinued within sixty (60) days after commencement of such proceeding or the
appointment of such trustee or receiver; or the making by Tenant or any
guarantor hereunder of an assignment for the benefit of creditors;

         (e) Tenant's failure to cause to be released or post a bond over any
mechanics liens filed against the Premises or the Project within twenty (20)
days after the date the same shall have been filed or recorded; or

                                      -22-

<PAGE>

         (f) Tenant's failure to observe or perform according to the provisions
of Articles 17 or 25 within five (5) business days after written notice from
Landlord.

         All defaults by Tenant of any covenant or condition of this Lease shall
be deemed by the parties hereto to be material.

ARTICLE 20 - REMEDIES
- ---------------------

         (a) Upon the occurrence of an Event of Default under this Lease as
provided in Article 19 hereof, Landlord may exercise all of its remedies as may
be permitted by law, including, but not limited to, the remedy provided by
Section 1951.4 of the California Civil Code, and including, without limitation,
terminating this Lease, re-entering the Premises and removing all persons and
property therefrom, which property may be stored by Landlord at a warehouse or
elsewhere at the risk, expense and for the account of Tenant. If Landlord elects
to terminate this Lease, Landlord shall be entitled to recover from Tenant the
aggregate of all amounts permitted by law, including, but not limited to (i) the
worth at the time of the amount of any unpaid rent which had been earned at the
time of such termination; plus (ii) the worth at the time of award of the amount
by which the unpaid rent 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; plus (iii) the worth at the time of award of
the amount by which the unpaid rent for the balance of the Lease Term after the
time of award exceeds the amount of such rental loss that Tenant proves could
have been reasonably avoided; plus (iv) 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, specifically including, but not limited to,
brokerage commissions and advertising expenses incurred, expenses of remodeling
the Premises or any portion thereof for a new tenant, whether for the same or a
different use, and any special concessions made to obtain a new tenant; and (v)
at Landlord's election, such other amounts in addition to or in lieu of the
foregoing as may be permitted from time to time by applicable law. The term
"rent" as used in this Article 20(a) shall be deemed to be and to mean all sums
of every nature required to be paid by Tenant pursuant to the terms of this
Lease, whether to Landlord or to others. As used in Items (i) and (ii), above,
the "worth at the time of award" shall be computed by allowing interest at the
rate set forth in Item (e), below, but in no case greater than the maximum
amount of such interest permitted by law. As used in Item (iii), above, the
"worth at the time of award" shall be computed by discounting such amount at the
discount rate of the Federal Reserve Bank of San Francisco at the time of award
plus one percent (1%).

         (b) Nothing in this Article 20 shall be deemed to affect Landlord's
right to indemnification for liability or liabilities arising prior to the
termination of this Lease for personal injuries or property damage under the
indemnification clause or clauses contained in this Lease.

         (c) Notwithstanding anything to the contrary set forth herein,
Landlord's re-entry to perform acts of maintenance or preservation of or in
connection with efforts to relet the Premises or any portion thereof, or the
appointment of a receiver upon Landlord's initiative to protect Landlord's
interest under this Lease shall not terminate Tenant's right to possession of
the Premises or any portion thereof and, until Landlord does elect to terminate
this Lease, this Lease shall continue in full force and effect, and Landlord may
enforce all of Landlord's rights and remedies hereunder including, without
limitation, the remedy described in California Civil Code Section 1951.4 (lessor
may continue lease in effect after lessee's breach and abandonment and recover
rent as it becomes due, if lessee has the right to sublet or assign, subject
only to reasonable limitations). Accordingly, if Landlord does not elect to
terminate this Lease on account of any default by Tenant, Landlord may, from
time to time, without terminating this Lease, enforce all of its rights and
remedies under this Lease, including the right to recover all rent as it becomes
due.

         (d) All rights, powers and remedies of Landlord hereunder and under any
other agreement now or hereafter in force between Landlord and Tenant shall be
cumulative and not

                                      -23-

<PAGE>

alternative and shall be in addition to all rights, powers and remedies given to
Landlord by law, and the exercise of one (1) or more rights or remedies shall
not impair Landlord's right to exercise any other right or remedy.

         (e) Any amount due from Tenant to Landlord hereunder which is not paid
when due shall bear interest at the lower of ten percent (10%) per annum, or the
maximum lawful rate of interest from the due date (subject to applicable cure
periods, if any) until paid, unless otherwise specifically provided herein, but
the payment of such interest shall not excuse or cure any default by Tenant
under this Lease. In addition to such interest: (i) if Basic Rental is not paid
within ten (10) days after written notice that the same is due, a late charge
equal to five percent (5%) of the amount overdue or Five Hundred Dollars
($500.00), whichever is greater, shall be assessed and shall accrue for each
calendar month or part thereof until such rental, including the late charge, is
paid in full, which late charge Tenant hereby agrees is a reasonable estimate of
the damages Landlord shall suffer as a result of Tenant's late payment; and (ii)
a charge of Twenty-Five Dollars ($25.00) shall be assessed for any check given
to Landlord by or on behalf of Tenant which is not honored by the drawee
thereof, which damages include Landlord's additional administrative and other
costs associated with such late payment and unsatisfied checks, and the parties
agree that it would be impracticable or extremely difficult to fix Landlord's
actual damage in such event. Such charges for interest and late payments and
unsatisfied checks are separate and cumulative and are in addition to and shall
not diminish or represent a substitute for any or all of Landlord's rights or
remedies under any other provision of this Lease.

ARTICLE 21 - TRANSFER OF LANDLORD'S INTEREST
- --------------------------------------------

         In the event of any transfer or termination of Landlord's interest in
the Premises or the Project by sale, assignment, transfer, foreclosure, deed in
lieu of foreclosure, or otherwise, whether voluntary or involuntary, Landlord
shall be automatically relieved of any and all obligations and liabilities on
the part of Landlord from and after the date of such transfer or termination,
including furthermore without limitation the obligation of Landlord under
Article 4 above and California Civil Code 1950.7 to return the security deposit,
provided said security deposit is transferred to said transferee. Tenant agrees
to attorn to the transferee upon any such transfer and to recognize such
transferee as the lessor under this Lease so long as such transferee assumes the
obligations of Landlord arising under this Lease from and after the date of such
transfer and Tenant shall, within five (5) days after request, execute such
further instruments or assurances as such transferee may reasonably deem
necessary to evidence or confirm such attornment.

ARTICLE 22 - BROKER
- -------------------

         In connection with this Lease, Landlord and Tenant each warrants and
represents to the other that it has had dealings only with firm(s) set forth in
Article 1.H. of the Basic Lease Provisions and that it knows of no other person
or entity who is or might be entitled to a commission, finder's fee or other
like payment in connection herewith and Landlord and Tenant each does hereby
indemnify and agree to hold the other party, its agents, members, partners,
representatives, officers, affiliates, shareholders, employees, successors and
assigns harmless from and against any and all loss, liability and expenses which
such other party may incur should such warranty and representation prove
incorrect, inaccurate or false.

ARTICLE 23 - PARKING
- --------------------

         Tenant shall have the right (but not the obligation) to use, free of
charge, the number of reserved and/or unreserved parking passes set forth in
Article 1(I) of the Basic Lease Provisions, which parking passes shall pertain
to the Project parking facility. Tenant's continued right to use the parking
passes is conditioned upon Tenant abiding by all rules and regulations which are
prescribed from time to time for the orderly operation and use of the parking
facility where the parking passes are located, including any sticker or other
identification system reasonably established by Landlord, Tenant's cooperation
in seeing that Tenant's employees and visitors also comply with such rules and
regulations, and Tenant not

                                      -24-

<PAGE>

being in default under this Lease, after applicable notice and cure provisions.
Landlord specifically reserves the right to change the size, configuration,
design, layout and all other aspects of the Project parking facility at any time
and Tenant acknowledges and agrees that Landlord may, without incurring any
liability to Tenant and without any abatement of rent under this Lease, from
time to time, close-off or restrict access to the Project parking facility for
purposes of permitting or facilitating any such construction, alteration or
improvements; provided that Landlord agrees to use its commercially reasonable
efforts to minimize any interference or disruption to Tenant as a result of any
such change. Landlord may delegate its responsibilities hereunder to a parking
operator or a lessee of the parking facility in which case such parking operator
or lessee shall have all the rights of control attributed hereby to the
Landlord. The parking passes used by Tenant pursuant to this Article 23 are
provided to Tenant solely for use by Tenant's own personnel and such passes may
not be transferred, assigned, subleased or otherwise alienated by Tenant without
Landlord's prior approval (except in connection with assignments and subleases
not requiring Landlord's prior approval).

ARTICLE 24 - WAIVER
- -------------------

         No waiver by Landlord of any provision of this Lease shall be deemed to
be a waiver of any other provision hereof or of any subsequent breach by Tenant
of the same or any other provision. No provision of this Lease may be waived by
Landlord, except by an instrument in writing executed by Landlord. Landlord's
consent to or approval of any act by Tenant requiring Landlord's consent or
approval shall not be deemed to render unnecessary the obtaining of Landlord's
consent to or approval of any subsequent act of Tenant, whether or not similar
to the act so consented to or approved. No act or thing done by Landlord or
Landlord's agents during the term of this Lease shall be deemed an acceptance of
a surrender of the Premises, and no agreement to accept such surrender shall be
valid unless in writing and signed by Landlord. Any payment by Tenant or receipt
by Landlord of an amount less than the total amount then due hereunder shall be
deemed to be in partial payment only thereof and not a waiver of the balance due
or an accord and satisfaction, notwithstanding any statement or endorsement to
the contrary on any check or any other instrument delivered concurrently
therewith or in reference thereto. Accordingly, Landlord may accept any such
amount and negotiate any such check without prejudice to Landlord's right to
recover all balances due and owing and to pursue its other rights against Tenant
under this Lease, regardless of whether Landlord makes any notation on such
instrument of payment or otherwise notifies Tenant that such acceptance or
negotiation is without prejudice to Landlord's rights.

ARTICLE 25 - ESTOPPEL CERTIFICATE
- ---------------------------------

         Tenant shall, at any time and from time to time, upon not less than
twenty (20) days' prior written notice from Landlord, execute, acknowledge and
deliver to Landlord a statement in writing certifying the following information
(but not limited to the following information in the event further information
is requested by Landlord): (a) that this Lease is unmodified and in full force
and effect (or, if modified, stating the nature of such modification and
certifying that this Lease, as modified, is in full force and effect); (b) the
dates to which the rental and other charges are paid in advance, if any; (c) the
amount of Tenant's security deposit, if any; and (d) acknowledging that there
are not, to the best of Tenant's knowledge, any uncured defaults on the part of
Landlord hereunder, and no events or conditions then in existence which, with
the passage of time or notice or both, would constitute a default on the part of
Landlord hereunder, or specifying such defaults, events or conditions, if any
are claimed. It is expressly understood and agreed that any such statement may
be relied upon by any prospective purchaser or encumbrancer of all or any
portion of the Real Property. Tenant's failure to deliver such statement within
such time shall constitute an admission by Tenant that all statements contained
therein are true and correct. Tenant agrees to execute all documents required in
accordance with this Article 25 within twenty (20) days after delivery of said
documents.

                                      -25-

<PAGE>

ARTICLE 26 - LIABILITY OF LANDLORD
- ----------------------------------

         Notwithstanding anything in this Lease to the contrary, any remedy of
Tenant for the collection of a judgment (or other judicial process) requiring
the payment of money by Landlord in the event of any default by Landlord
hereunder or any claim, cause of action, obligation, contractual statutory or
otherwise by Tenant against Landlord concerning, arising out of or relating to
any matter relating to this Lease and all of the covenants and conditions or any
obligations, contractual, statutory, or otherwise set forth herein, shall be
limited solely and exclusively to an amount which is equal to the interest of
Landlord in and to the Project. No other property or assets of Landlord, or any
member, officer, director, shareholder, partner, trustee, agent, servant or
employee of Landlord ("Representative") shall be subject to levy, execution or
other enforcement procedure for the satisfaction of Tenant's remedies under or
with respect to this Lease, Landlord's obligations to Tenant, whether
contractual, statutory or otherwise, the relationship of Landlord and Tenant
hereunder, or Tenant's use or occupancy of the Premises. Tenant further
understands that Landlord shall not incur any additional liability, duty or
obligation to Tenant arising from and after the date that Landlord or any of
Landlord's Representatives no longer have any right, title or interest in or to
the Project.

ARTICLE 27 - INABILITY TO PERFORM
- ---------------------------------

         This Lease and the obligations of Landlord and Tenant hereunder shall
not be affected or impaired because Landlord or Tenant, as the case may be, is
unable to fulfill any of its obligations hereunder or is delayed in doing so, if
such inability or delay is caused by reason of any prevention, delay, stoppage
due to strikes, lockouts, acts of God, or any other cause previously, or at such
time, beyond the reasonable control or anticipation of such party (collectively,
a "Force Majeure"), and such party's obligations under this Lease shall be
forgiven and suspended by any such Force Majeure.

ARTICLE 28 - HAZARDOUS WASTE
- ----------------------------

         (a) Tenant shall not cause or permit any Hazardous Material (as defined
in Article 28(d) below) to be brought, kept or used in or about the Project by
Tenant, its agents, employees, contractors, or invitees except for small
quantities of normal office supplies (i.e., liquid paper, toner fluid, . . . )
used in compliance with all Hazardous Materials Laws. Tenant indemnifies
Landlord from and against any breach by Tenant of the obligations stated in the
preceding sentence, and agrees to defend and hold Landlord harmless from and
against any and all claims, judgments, damages, penalties, fines, costs,
liabilities, or losses (including, without limitation, diminution in value of
the Project, damages for the loss or restriction or use of rentable or usable
space or of any amenity of the Project, damages arising from any adverse impact
or marketing of space in the Project, and sums paid in settlement of claims,
attorneys' fees, consultant fees, and expert fees) which arise during or after
the term of this Lease as a result of such breach. This indemnification of
Landlord by Tenant includes, without limitation, costs incurred in connection
with any investigation of site conditions or any cleanup, remedial, removal, or
restoration work required by any federal, state, or local governmental agency or
political subdivision because of Hazardous Material present in the soil or
ground water on or under the Project. Without limiting the foregoing, if the
presence of any Hazardous Material on the Project caused or permitted by Tenant
results in any contamination of the Project and subject to the provisions of
Articles 9, 10 and 11 hereof, Tenant shall promptly take all actions at its sole
expense as are necessary to return the Project to the condition existing prior
to the introduction of any such Hazardous Material and the contractors to be
used by Tenant for such work must be approved by Landlord, which approval shall
not be unreasonably withheld so long as such actions would not potentially have
any material adverse long-term or short-term effect on the Project and so long
as such actions do not materially interfere with the use and enjoyment of the
Project by the other tenants thereof.

         (b) Intentionally Omitted

                                      -26-

<PAGE>

         (c) It shall not be unreasonable for Landlord to withhold its consent
to any proposed transfer if (i) the proposed transferee's anticipated use of the
Premises involves the generation, storage, use, treatment, or disposal of
Hazardous Material (other than as permitted above); (ii) the proposed transferee
has been required by any prior landlord, lender, or governmental authority to
take remedial action in connection with Hazardous Material contaminating a
property if the contamination resulted from such transferee's actions or use of
the property in question; or (iii) the proposed transferee is subject to an
Enforcement Order issued by any governmental authority in connection with the
use, disposal, or storage of a Hazardous Material.

         (d) As used herein, the term "Hazardous Material" means any hazardous
or toxic substance, material, or waste which is or becomes regulated by any
local governmental authority, the State of California or the United States
Government. The term "Hazardous Material" includes, without limitation, any
material or substance which is (i) defined as "Hazardous Waste", "Extremely
Hazardous Waste", or "Restricted Hazardous Waste" under Sections 25115, 25117 or
25122.7, or listed pursuant to Section 25140 of the California Health and Safety
Code, Division 20, Chapter 6.5 (Hazardous Waste Control Law); (ii) defined as a
"Hazardous Substance" under Section 25316 of the California Health and Safety
Code, Division 20, Chapter 6.8 (Carpenter-Presley-Tanner Hazardous Substance

"Hazardous Waste" under Section 25501 of the California Health and Safety Code,
Division 20, Chapter 6.95 (Hazardous Materials Release Response Plans and
Inventory); (iv) defined as a "Hazardous Substance" under Section 25281 of the
California Health and Safety Code, Division 20, Chapter 6.7 (Underground Storage
of Hazardous Substances); (v) petroleum; (vi) asbestos; (vii) listed under
Article 9 or defined as "Hazardous" or "Extremely Hazardous" pursuant to Article
11 of Title 22 of the California Administrative Code, Division 4, Chapter 20;
(viii) designated as a "Hazardous Substance" pursuant to Section 311 of the
Federal Water Pollution Control Act (33 U.S.C. Section 1317); (ix) defined as a
"Hazardous Waste" pursuant to Section 1004 of the Federal Resource Conservation
and Recovery Act, 42 U.S.C. Section 6901, et seq. (42 U.S.C. Section 6903); or
(x) defined as a "Hazardous Substance" pursuant to Section 101 of the
Comprehensive Environmental Response, Compensation and Liability Act, 42 U.S.C.
Section 9601, et seq. (42 U.S.C. Section 9601).

         (e) As used herein, the term "laws" means any applicable federal, state
or local law, ordinance, or regulation relating to any Hazardous Material
affecting the Project, including, without limitation, the laws, ordinances, and
regulations referred to in Article
28 (d) above.

         (f) Landlord represents to Tenant that, to the best of Landlord's
actual knowledge (without any independent inquiry or investigation), Landlord
has not received any notice from any governmental authority that the Premises or
the Project are in violation of any laws as of the date of this Lease. Landlord
shall indemnify, defend and hold harmless Tenant, its officers, directors,
employees and agents harmless from and against any and all claims, judgments,
damages, penalties, fines, costs, liabilities or losses and attorneys' fees
arising out of (i) any hazardous materials in, on or about the Project or the
Premises as of the dates of this Lease, and (ii) any Hazardous Materials which
were created, handled, placed, stored, used, transported or disposed of by
Landlord or Landlord's agents, after the dates of this Lease, excluding,
however, any Hazardous Materials whose presence was caused by Tenant or any of
Tenant's agents, employees, representatives or invitees.

ARTICLE 29 - SURRENDER OF PREMISES; REMOVAL OF PROPERTY
- -------------------------------------------------------

         (a) The voluntary or other surrender of this Lease by Tenant to
Landlord, or a mutual termination hereof, shall not work a merger, and shall at
the option of Landlord, operate as an assignment to it of any or all subleases
or subtenancies affecting the Premises.

                                      -27-

<PAGE>

         (b) Upon the expiration of the term of this Lease, or upon any earlier
termination of this Lease, Tenant shall quit and surrender possession of the
Premises to Landlord in as good order and condition as the same are now and
hereafter may be improved by Landlord or Tenant, reasonable wear and tear,
casualty and repairs which are Landlord's obligation excepted, and shall,
without expense to Landlord, remove or cause to be removed from the Premises all
debris and rubbish, all furniture, equipment, business and trade fixtures,
free-standing cabinet work, moveable partitioning and other articles of personal
property owned by Tenant or installed or placed by Tenant at its own expense in
the Premises, and all similar articles of any other persons claiming under
Tenant unless Landlord exercises its option to have any subleases or
subtenancies assigned to it, and Tenant shall repair all damage to the Premises
resulting from the installation and removal of such items to be removed.

         (c) Whenever Landlord shall re-enter the Premises as provided in
Article 12 hereof, or as otherwise provided in this Lease, any property of
Tenant not removed by Tenant upon the expiration of the term of this Lease (or
within forty-eight (48) hours after a termination by reason of Tenant's
default), as provided in this Lease, shall be considered abandoned, and Landlord
may remove any or all of such items and dispose of the same in any manner
permitted by law or store the same in a public warehouse or elsewhere for the
account and at the expense and risk of Tenant, and if Tenant shall fail to pay
the cost of storing any such property after it has been stored for a period of
ninety (90) days or more, Landlord may sell any or all of such property at
public or private sale, in such manner and at such times and places as Landlord,
in its sole discretion, may deem proper, without notice or to demand upon
Tenant, for the payment of all or any part of such charges or the removal of any
such property, and shall apply the proceeds of such sale as follows: first, to
the cost and expense of such sale, including reasonable attorneys' fees for
services rendered; second, to the payment of the cost of or charges for storing
any such property; third, to the payment of any other sums of money which may
then or thereafter be due to Landlord from Tenant under any of the terms hereof;
and fourth, the balance, if any, to Tenant.

         (d) All fixtures, equipment, Alterations and/or appurtenances attached
to or built into the Premises prior to or during the term of the Lease (other
than Tenant's personal property and trade fixtures), whether by Landlord or
Tenant and whether at the expense of Landlord or Tenant, or of both, shall be
and remain part of the Premises and shall not be removed by Tenant at the end of
the term unless otherwise expressly provided for in this Lease or unless such
removal is required by Landlord pursuant to the provisions of Article 9 above.
Such fixtures, equipment, alterations, additions, improvements and/or
appurtenances shall include, but not be limited to all floor coverings, drapes,
paneling, built-in cabinetry, molding, doors, vaults (including vault doors),
plumbing systems, electrical systems, lighting systems, silencing equipment,
communication systems, all fixtures and outlets for the systems mentioned above
and for all telephone, radio, telegraph and television purposes, and any special
flooring or ceiling installations.

ARTICLE 30 - MISCELLANEOUS
- --------------------------

         (a) SEVERABILITY; ENTIRE AGREEMENT. Any provision of this Lease which
shall prove to be invalid, void, or illegal shall in no way affect, impair or
invalidate any other provision hereof, and any such other provisions shall
remain in full force and effect. This Lease and the exhibits and any Addendum
attached hereto constitute the entire agreement between the parties hereto with
respect to the subject matter hereof, and no prior agreement or understanding
pertaining to any such matter shall be effective for any purpose. No provision
of this Lease may be amended or supplemented except by an agreement in writing
signed by the parties hereto or their successor-in-interest.

         (b)      ATTORNEYS' FEES; WAIVER OF JURY TRIAL.

                  (i) In any action to enforce the terms of this Lease,
including any suit by Landlord for the recovery of rent or possession of the
Premises, the losing party shall pay the successful party a reasonable sum for
attorneys' fees in such suit and such attorneys' fees shall be deemed to have
accrued prior to the commencement of such action and shall be paid whether or
not such action is prosecuted to judgment.

                  (ii) Should Landlord, without fault on Landlord's part, be
made a party to any litigation instituted by Tenant or by any third party
against Tenant, or by or against any person holding under or using the Premises
by license of Tenant, or for the foreclosure of any lien for labor or material
furnished to or for Tenant or any such other person or otherwise arising out of
or resulting from any act or transaction of Tenant or of any such other person,
Tenant covenants to save and hold Landlord harmless from any judgment rendered
against Landlord or the Premises or any part thereof and from all costs and
expenses, including reasonable attorneys' fees incurred by Landlord in
connection with such litigation.

                  (iii) When legal services are rendered by an attorney at law
who is an employee of a party, attorneys' fees incurred by that party shall be
deemed to include an amount based upon the number of hours spent by such
employee on such matters multiplied by an appropriate billing rate determined by
taking into consideration the same factors, including but not limited by, the
importance of the matter, seniority, qualifications, time applied, difficulty
and results, as are considered when an attorney not in the employ of a party is
engaged to render such service.

                  (iv) EACH PARTY HEREBY WAIVES ANY RIGHT TO A TRIAL BY JURY IN
ANY ACTION SEEKING SPECIFIC PERFORMANCE OF ANY PROVISION OF THIS LEASE, FOR
DAMAGES FOR ANY BREACH UNDER THIS LEASE, OR OTHERWISE FOR ENFORCEMENT OF ANY
RIGHT OR REMEDY HEREUNDER.

         (c) TIME OF ESSENCE. Each of Tenant's covenants herein is a condition,
and time is of the essence with respect to the performance of every provision of
this Lease.

         (d) HEADINGS; JOINT AND SEVERAL. The article headings contained in
this Lease are for convenience only and do not in any way limit or amplify any
term or provision hereof. The terms "Landlord" and "Tenant" as used herein shall
include the plural as well as the singular, the neuter shall include the
masculine and feminine genders and the obligations herein imposed upon Tenant
shall be joint and several as to each of the persons, firms or corporations of
which Tenant may be composed.

         (e) RESERVED AREA. Tenant hereby acknowledges and agrees that the
exterior walls of the Premises and the area between the finished ceiling of the
Premises and the slab of the floor of the Project thereabove have not been
demised hereby, and the use thereof, together with the right to install,
maintain, use, repair and replace pipes, ducts, conduits and wires leading
through, under or above the Premises in locations which will not materially
interfere with Tenant's use of the Premises and serving other parts of the
Project, are hereby excepted and reserved unto Landlord.

         (f) NO OPTION. The submission of this Lease by Landlord, its agent or
representative for examination or execution by Tenant does not constitute an
option or offer to Lease the Premises upon the terms and conditions contained
herein or a reservation of the Premises in favor of Tenant, it being intended
hereby that this Lease shall only become effective upon the execution hereof by
Landlord and delivery of a fully executed lease to Tenant.

                                      -29-

<PAGE>

         (g) USE OF PROJECT NAME; IMPROVEMENTS. Tenant shall not be allowed to
use the name, picture or representation of the Project, or words to that effect,
in connection with any business carried on in the Premises or otherwise (except
at Tenant's address) without the prior written consent of Landlord. In the event
that Landlord undertakes any additional improvements on the Real Property,
including but not limited to new construction or renovation or additions to the
existing improvements, Landlord shall not be liable to Tenant for any noise,
dust, vibration or interference with access to the Premises or disruption in
Tenant's business caused thereby; provided, however, in the event such
disruption or interference materially and adversely interferes with the
operation of Tenant's business in the Premises for more than five (5)
consecutive business days, then from and after such fifth (5th) business day,
the Basic Rental shall be equitably abated during the continuance of such
disruption or interference.

         (h) RULES AND REGULATIONS. Tenant shall observe faithfully and comply
strictly with the Rules and Regulations attached to this Lease as Exhibit "B"
and made a part hereof, and such other rules and regulations as Landlord may
from time to time reasonably adopt for the safety, care and cleanliness of the
Project, the facilities thereof, or the preservation of good order therein.
Landlord shall not be liable to Tenant for violation of any such rules and
regulations, or for the breach of any covenant or condition in any Lease by any
other tenant in the Project; provided, however, that Landlord shall enforce the
Rules and Regulations in a non-discriminatory manner. A waiver by Landlord of
any rule or regulation for any other tenant shall not constitute nor be deemed a
waiver of the rules or regulations for this Tenant. Landlord agrees to enforce
said Rules and Regulations in a non-discriminatory manner against all tenants of
the Project.

         (i) QUIET POSSESSION. Upon Tenant's paying the Basic Rent, Additional
Rent and other sums provided hereunder and observing and performing all of the
covenants, conditions and provisions on Tenant's part to be observed and
performed hereunder, Tenant shall have quiet possession of the Premises for the
entire term hereof, subject to all of the provisions of this Lease.

          (j) RENT. All payments required to be made hereunder to Landlord shall
be deemed to be rent, whether or not described as such.

         (k) SUCCESSORS AND ASSIGNS. Subject to the provisions of Article 15
hereof, all of the covenants, conditions and provisions of this Lease shall be
binding upon and shall inure to the benefit of the parties hereto and their
respective heirs, personal representatives, successors and assigns.

         (l) NOTICES. Any notice required or permitted to be given hereunder
shall be in writing and may be given by personal service evidenced by a signed
receipt or sent by registered or certified mail, return receipt requested,

         (m) PERSISTENT DELINQUENCIES. In the event that Tenant shall be
delinquent by more than fifteen (15) days in the payment of rent on three (3)
separate occasions in any twelve (12) month period, Landlord shall have the
right to collect rent quarterly in advance.

performed by Tenant under any of the terms of this Lease shall be performed by
Tenant at Tenant's sole cost and expense and without any abatement of rent,
except as provided herein. If Tenant shall fail to pay any sum of money, other
than rent, 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
beyond any applicable cure period set forth in this Lease, Landlord may, but

thereon at the rate of ten percent (10%) per annum from the date of such payment
by Landlord, shall be payable to Landlord on demand, and Tenant covenants to pay
any such sums, and Landlord shall have (in addition to any other right or remedy
of Landlord) the same rights and remedies in the event of the non-payment

fixtures and equipment thereof, as well as in or to the street entrances, halls,
passages, elevators, stairways and other improvements thereof, as it may deem
reasonably necessary or desirable, provided such changes do not materially and
adversely impair Tenant's ability to conduct its business operations from the
Premises.

reserves the right to change the name or address of the Project at any time.

         (v) EXHIBITS AND ADDENDUM. The Exhibits and Addendum, if applicable,
attached hereto are incorporated herein by this reference as if fully set forth
herein.

ARTICLE 31 - OPTION TO EXTEND
- -----------------------------

         (a) OPTION RIGHT. Landlord hereby grants the Tenant named in this Lease
and to any Tenant Affiliate ("Original Tenant") one (1) option (the "Option") to
extend the Lease term for a period of five (5) years (the "Option Term"), which
Option shall be exercisable only by written notice delivered by Tenant to
Landlord as set forth below. The rights contained in this Article 31 shall be
personal to the Original Tenant and may only be exercised by the Original Tenant
(and not any assignee, sublessee or other transferee of the Original Tenant's
interest in this Lease).

         (b) OPTION RENT. The rent payable by Tenant during the Option Term
("Option Rent") shall be equal to the "Market Rent" (defined below) but in no
event shall the Option Rent be less than Tenant is paying under the Lease on the
month immediately preceding the Option Term for Monthly Basic Rental, including
all escalations, any Excess, additional rent and other charges. "Market Rent"
shall mean the applicable Monthly Basic Rental, including all escalations, any
Excess, additional rent and other charges at which tenants, as of the
commencement of the Option Term, are leasing non-sublease, non-encumbered, space
comparable in size, location and quality to the Premises in renewal transactions
for a term comparable to the Option Term, which comparable space is located in
office buildings comparable to the Project in the Thousand Oaks/Westlake Village
office market area, taking into consideration the value of the existing
improvements in the Premises to Tenant, as compared to the value of the existing
improvements in such comparable space, with such value to be based upon the age,
quality and layout of the improvements and the extent to which the same could be
utilized by Tenant with consideration given to the fact that the improvements
existing in the Premises are specifically suitable to Tenant.

                                      -32-

<PAGE>

         (c) EXERCISE OF OPTIONS. The Option shall be exercised by Tenant only
in the following manner: (i) Tenant shall not be in default on the delivery date
of the Interest Notice and Tenant's Acceptance; (ii) Tenant shall deliver
written notice ("Interest Notice") to Landlord not more than ten (10) months nor
less than eight (8) months prior to the expiration of the Lease Term, stating
that Tenant is interested in exercising the Option, (iii) within fifteen (15)
business days of Landlord's receipt of Tenant's written notice, Landlord shall
deliver notice ("Option Rent Notice") to Tenant setting forth the Option Rent;
and (iv) if Tenant desires to exercise such Option, Tenant shall provide
Landlord written notice within five (5) business days after receipt of the
Option Rent Notice ("Tenant's Acceptance") and upon, and concurrent with such
exercise, Tenant may, at its option, object to the Option Rent contained in the
Option Rent Notice. Tenant's failure to deliver the Interest Notice or Tenant's
Acceptance on or before the dates specified above shall be deemed to constitute
Tenant's election not to exercise the Option. If Tenant timely and properly
exercises its Option, the Lease Term shall be extended for the Option Term upon
all of the terms and conditions set forth in this Lease, except that the rent
for the Option Term shall be as indicated in the Option Rent Notice unless
Tenant, concurrently with Tenant's Acceptance, objects to the Option Rent
contained in the Option Rent Notice, in which case the parties shall follow the
procedure and the Option Rent shall be determined, as set forth in Section 31(d)
below.

         (d) DETERMINATION OF MARKET RENT. If Tenant timely and appropriately
objects to the Option Rent in Tenant's Acceptance, Landlord and Tenant shall
attempt to agree upon the Market Rent using their best good-faith efforts. If
Landlord and Tenant fail to reach agreement within twenty-one (21) days
following Tenant's Acceptance ("Outside Agreement Date"), then each party shall
make a separate determination of the Market Rent which shall be submitted to
each other and to arbitration in accordance with the following items (i) through
(vii):

                  (i) Landlord and Tenant shall each appoint, within ten (10)
days of the Outside Agreement Date, one arbitrator who shall by profession be a
current real estate broker or appraiser of comparable properties in the
immediate vicinity of the Project, and who has been active in such field over
the last five (5) years, and who has not been retained or employed by either
party during the prior twelve (12) months. The determination of the arbitrators
shall be limited solely to the issue of whether Landlord's or Tenant's submitted
Market Rent is the closest to the actual Market Rent as determined by the
arbitrators, taking into account the requirements of item (b), above.

                  (ii) The two (2) arbitrators so appointed shall within five
(5) business days of the date of the appointment of the last appointed
arbitrator agree upon and appoint a third arbitrator who shall be qualified
under the same criteria set forth hereinabove for qualification of the initial
two (2) arbitrators.

                  (iii) The three (3) arbitrators shall within fifteen (15) days
of the appointment of the third arbitrator reach a decision as to whether the
parties shall use Landlord's or Tenant's submitted Market Rent, and shall notify
Landlord and Tenant thereof.

                  (iv) The decision of the majority of the three (3) arbitrators
shall be binding upon Landlord and Tenant.

                  (v) If either Landlord or Tenant fails to appoint an
arbitrator within ten (10) days after the applicable Outside Agreement Date, the
arbitrator appointed by one of them shall reach a decision, notify Landlord and
Tenant thereof, and such arbitrator's decision shall be binding upon Landlord
and Tenant.

                  (vi) If the two arbitrators fail to agree upon and appoint a
third arbitrator, or both parties fail to appoint an arbitrator, then the
appointment of the third arbitrator shall be dismissed and the matter to be
decided shall be forthwith submitted to arbitration under the provisions of the
American Arbitration Association, but subject to the instruction set forth in
this item (vi).

                                      -33-

<PAGE>

                  (vii) The cost of arbitration shall be paid by Landlord and
Tenant equally.

ARTICLE 32 - RIGHT OF FIRST OFFER
- ---------------------------------

         (a) Landlord hereby grants to Tenant a right of first offer with
respect to any available space in the balance of the Project (but not in the
office building located at 2535 Townsgate Road, Westlake Village) ("First Offer
Space"). Notwithstanding the foregoing, (i) such first offer right of Tenant
shall commence only following the expiration or earlier termination of (A) any
existing lease pertaining to the First Offer Space, and (B) as to any First
Offer Space which is vacant as of the date of this Lease, the first lease
pertaining to any portion of such First Offer Space entered into by Landlord
after the date of this Lease (collectively, the "Superior Leases"), including
any renewal of such existing or future lease, whether or not such renewal is
pursuant to an express written provision in such lease, and regardless of
whether any such renewal is consummated pursuant to a lease amendment or a new
lease, and (ii) such first offer right shall be subordinate and secondary to all
rights of expansion, first refusal, first offer or similar rights granted to (A)
the tenants of the Superior Leases and (B) any other tenant of the project and
identified on Exhibit "H" attached hereto (the rights described in items (i) and
(ii), above to be known collectively as "Superior Rights"). Tenant's right of
first offer shall be on the terms and conditions set forth in this Article 32.

                  (i) Procedure for Offer. Landlord shall notify Tenant ("First
Offer Notice") from time to time when Landlord determines that Landlord shall
commence the marketing of any First Offer Space because such space shall become
available for lease to third parties, where no holder of a Superior Right
desires to lease such space. The First Offer Notice shall describe the space so
offered to Tenant and shall set forth Landlord's proposed economic terms and
conditions applicable to Tenant's lease of such space (collectively, the
"Economic Terms"). Notwithstanding the foregoing, Landlord's obligation to
deliver the First Offer Notice shall not apply during the last eight (8) months
of the initial Lease Term unless Tenant has timely delivered Tenant's Acceptance
to Landlord pursuant to Article 31 above.

                  (ii) Procedure for Acceptance. If Tenant wishes to exercise
Tenant's right of first offer with respect to the space described in the First
Offer Notice, then within five (5) business days after delivery of the First
Offer Notice to Tenant, Tenant shall deliver notice to Landlord of Tenant's
exercise its right of first offer with respect to the entire space described in
the First Offer Notice. If concurrently with Tenant's exercise of the first
offer right, Tenant notifies Landlord that it does not accept the Economic Terms
set forth in the First Offer Notice, Landlord and Tenant shall, for a period of
fifteen (15) days after Tenant's exercise, negotiate in good faith to reach
agreement as to such Economic Terms. If Tenant does not so notify Landlord that
it does not accept the Economic Terms set forth in the First Offer Notice
concurrently with Tenant's exercise of the first offer right, the Economic Terms
shall be as set forth in the First Offer Notice. In addition, if Tenant does not
exercise its right of first offer within the five (5) business day period, or,
if Tenant exercises its first offer right but timely objects to Landlord's
determination of the Economic Terms and if Landlord and Tenant are unable to
reach agreement on such Economic Terms within said fifteen (15) day period, then
Landlord shall be free to lease the space described in the First Offer Notice to
anyone to whom Landlord desires on any terms Landlord desires and Tenant's right
of first offer shall terminate as to the First Offer Space described in the
First Offer Notice. Notwithstanding anything to the contrary contained herein,
Tenant must elect to exercise its right of first offer, if at all, with respect
to all of the space offered by Landlord to Tenant at any particular time, and
Tenant may not elect to lease only a portion thereof.

                  (iii) Construction of First Offer Space. Except as otherwise
included in the Economic Terms, Tenant shall take the First Offer Space in its
"as-is" condition, and Tenant shall be entitled to construct improvements in the
First Offer Space in accordance with the provisions of Article 9 of this Lease.

                                      -34-

<PAGE>

                  (iv) Lease of First Offer Space. If Tenant timely exercises
Tenant's right to lease the First Offer Space as set forth herein, Landlord and
Tenant shall execute an amendment adding such First Offer Space to this Lease
upon the same non-economic terms and conditions as applicable to the initial
Premises, and the economic terms and conditions as provided in this Article 32.
Tenant shall commence payment of rent for the First Offer Space and the Lease
Term of the First Offer Space shall commence upon the date of delivery of such
space to Tenant. The Lease Term for the First Offer Space shall expire
co-terminously with Tenant's lease of the initial Premises.

                  (v) No Defaults. The rights contained in this Article 32 shall
be personal to the Original Tenant, and may only be exercised by the Original
Tenant (and not any assignee, sublessee or other transferee of the Original
Tenant's interest in this Lease) if Tenant occupies the entire Premises as of
the date of the First Offer Notice. Tenant shall not have the right to lease
First Offer Space as provided in this Article 32 if, as of the date of the First
Offer Notice, or, at Landlord's option, as of the scheduled date of delivery of
such First Offer Space to Tenant, Tenant is in default under this Lease, after
the expiration of applicable notice and cure periods, or Tenant has previously
been in default under this Lease more than two times.

ARTICLE 33 - MUST TAKE SPACE
- ----------------------------

         Commencing on the Must Take Commencement Date (defined below), Tenant
hereby agrees to add to the Premises the Must Take Space. Tenant's lease of the
Must Take Space shall be on the same terms and conditions as affect the original
Premises throughout the Lease Term, including, without limitation, the same
Basic Rental rate (per rentable square foot) as then applies to the original
Premises (as set forth in Article 1.C. of the Basic Lease Provisions above);
provided, however, that (a) Tenant's Proportionate Share shall be increased to
take into account the additional number of rentable square feet of the Must Take
Space, and (b) except for the performance of the Tenant Improvements, the Must
Take Space shall be leased to Tenant in its then "as is" condition. The term
"Must Take Commencement Date" shall mean the earlier of (i) the date Tenant
first commences to conduct business from at least twenty-five percent (25%) of
the Must Take Space, or (ii) October 1, 1999. The term "Must Take Space" shall
mean the balance of that portion of the Premises which is located on the second
floor (other than the 4,000 rentable square feet referred to herein as Suite
200), which balance contains 13,048 rentable square feet (which square footage
Landlord and Tenant stipulate and agree is true and correct).

ARTICLE 34 - TOP OF BUILDING SIGNAGE
- ------------------------------------

                  (i) Subject to the approval of all necessary governmental or
regulatory agencies with jurisdiction over the Project, and provided (a)
Original Tenant directly leases from Landlord and occupies no less than fifty
percent (50%) of the total rentable square footage of the Project, and (b)
Original Tenant is not in default under this Lease, after the expiration of
applicable notice and cure periods, Original Tenant (and not any assignee,
sublessee, or other transferee of the Original Tenant's interest in this Lease)
shall have the right to install one (1) non-exclusive exterior sign at the top
of the Project (the "Top of Building Signage"), the size, location, method of
attachment, design and all other aspects of said signage to be subject to the
approval of Landlord. Original Tenant shall be solely responsible for all costs
incurred in connection with the purchase and initial installation of said Top of
Building Signage. Original Tenant shall furthermore be solely responsible for
all costs associated with maintaining, operating or otherwise repairing said Top
of Building Signage. At the expiration or earlier termination of this Lease, or
in the event the conditions precedent to the grant of said Top of Building
Signage to Original Tenant are no longer satisfied, Original Tenant shall remove
said signage, at its sole expense, and repair any damage to the Project or
otherwise caused by said removal. Tenant's Top of Building signage shall be
subject to the rules and regulations attached hereto as Exhibit "G".

                  (ii) Provided Tenant is not in default under this Lease,
Tenant, at Tenant's expense, shall have the right to (A) a building standard
number of lines on the directory board in the lobby of the Project, and (B)
building standard suite entrance signage.

                                      -35-

ARTICLE 35 - GENERATOR
- ----------------------

         (a) Subject to obtaining any necessary governmental and regulatory
approvals and the approval of Landlord, in Landlord's sole discretion, as to its
design, location and construction, Tenant shall have the right to install an
emergency power generator at the Project, together with the cabling or wiring
necessary to connect the generator to the Premises (collectively, the
"Generator"). All costs and expenses for the equipment, installation, connection
to and the maintenance, repair and operation of the Generator during the Term
shall be the sole responsibility of Tenant. Tenant shall not be charged any rent
or other fees for the location in which the Generator is placed, provided that
if the Generator is located on one (1) or more parking stalls, the number of
reserved parking stalls otherwise allocated to Tenant pursuant to Article 1.I.
of the Basic Lease Provisions shall be reduced by the number of parking stalls
used to accommodate the Generator. Tenant shall be entitled to install battery
backup systems in the Premises.

         (b) Landlord shall have the right from time to time during the Term to
have Tenant relocate the Generator, provided Landlord shall give Tenant prior
notice of the need to relocate the Generator, and shall coordinate such
relocation with Tenant so as not to interfere with or interrupt Tenant's use of
the Generator. The cost of any such relocation shall be borne by Tenant to the
extent such relocation is required by any act or omission by Tenant or as a
result of any law, ordinance, rule, regulation or statute affecting the Project
which was not in effect as of the date of this Lease; otherwise, said relocation
cost shall be borne by Landlord. Landlord may require, in Landlord's sole and
absolute discretion, that the Generator be screened from view by a screen which
shall be constructed by Tenant, at Tenant's cost, in accordance with the
specifications provided to Tenant by Landlord. To the extent Landlord
determines, in its reasonable discretion, that the plans and specifications for
the installation of the Generator need to be reviewed by an outside consultant,
Tenant shall reimburse Landlord for all out-of-pocket costs incurred by Landlord
in connection with such review. Tenant agrees that upon the expiration or
earlier termination of this Lease, Tenant shall remove the Generator, all
related cabling and/or wiring in accordance with all applicable governmental and
regulatory requirements and repair all damage to the Project where the Generator
was installed caused thereby and restore all such items in the area to the
extent reasonably necessary to effect a complete and effective repair to their
condition prior to the installation of the Generator, ordinary wear and tear
excepted.

         (c) The installation of the Generator shall be completed in a good and
workmanlike manner and in accordance with all laws, ordinances, rules,
regulations and orders affecting the Project, as well as the requirements set
forth in Article 9 above.

         (d) Tenant shall be responsible for obtaining, if required, any
building permits and any licenses or permits required by any governmental agency
having jurisdiction over the Project. Landlord agrees to reasonably assist and
cooperate, at no expense to Landlord, with Tenant to obtain any appropriate
licenses or permits. Notwithstanding anything to the contrary contained herein,
the engineering with respect to the installation of the Generator shall be
coordinated through the Project's designated engineers.

ARTICLE 36 - TERMINATION OPTION
- -------------------------------

TERMINATION RIGHT.

         (a) Tenant shall have the one-time option (the "Termination Option") to
terminate the entire Lease, but not any portion of the Lease. Such termination
shall be effective at any time after the last day of the month which is
forty-two (42) months after the month in which the Commencement Date falls (the
"Termination Date"), upon the following terms and conditions:

                                      -36-

<PAGE>

                  (i) Tenant gives Landlord written notice (the "Termination
Notice") of Tenant's election to exercise the Termination Option on or before
5:00 p.m. Pacific Standard Time on or before the date which is no less than
seven (7) months prior to the Termination

                  (ii) There exists no Event of Default under the Lease on the
date of the Termination Notice or on the Termination Date;

                  (iii) Tenant shall pay to Landlord no later than the date
which is four (4) months prior to the Termination Date an amount equal to the

Leasing Costs at 8% per annum from the date they were paid. The term "Leasing
Costs" shall mean the sum of (A) all costs and expenses incurred by Landlord in

such amount.

         (b) In the event Tenant timely and properly exercises the Termination
Option, the term of the Lease shall terminate effective as of the Termination
Date. Basic Rental and all other monetary obligations under the Lease shall be
paid through and apportioned as of the Termination Date, and neither Landlord
nor Tenant shall have any rights, liabilities or obliga tions accruing under the
Lease after the Termination Date, except for such rights and liabilities which,
by the terms of the Lease are obligations of the Tenant or Landlord which
expressly survive the expiration of the Lease. The Termination Option shall
automatically terminate and become null and void upon (a) the failure of Tenant
to timely or properly exercise the Termination Option; or (b) Tenant's right to
possession of the Premises being terminated prior to the exercise of the
Termination Option.


         IN WITNESS WHEREOF, the parties have executed this Lease, consisting of
the foregoing provisions and Articles, including all exhibits and other
attachments referenced therein, as of the date first above written.

<PAGE>

termination shall be effective at any time after the last day of the month

Rental and all other monetary obligations under the Lease with respect to the
Expansion Premises only shall be paid through and apportioned as of the
Expansion Termination Date, and neither Landlord nor Tenant shall have any
rights, liabilities or obligations accruing under the Lease after the
Expansion Termination Date, except for such rights and liabilities which, by
the terms of the Lease are obligations of the Tenant or Landlord which
expressly survive the expiration of the Lease; and

             (ii) Tenant shall, at its expense, prior to the Expansion
Termination Date, restore the Initial Expansion Premises to the same
condition which existed prior to the date of the Original Lease (i.e., the
condition which existed prior to the date that any work in connection with
the Expansion Improvements was commenced at the Project), and repair any
damage to the Project or Initial Expansion Premises as a result of such
restoration.


                                      -4-

         (c) The Expansion Termination Option shall automatically terminate
and become null and void upon (i) the failure of Tenant to timely or properly
exercise the Expansion Termination Option; or (ii) Tenant's right to
possession of the Expansion Premises being terminated prior to the exercise
of the Expansion Termination Option.

         (d) Notwithstanding the length of the amortization period set forth
in paragraph 8(a)(iii) above with respect to the Expansion Termination Fee,
Article 36(a)(iii) of the Lease shall be amended to provide that the length
of the amortization period with respect to the "Termination Fee" shall be
seven (7) years, commencing on the Commencement Date and expiring on the
seven (7) year anniversary of the Commencement Date.

         9. PARKING. Commencing on the Expansion Premises Commencement Date,
the number of unreserved parking passes which Tenant is entitled to use
within the Project's parking structure shall be increased by sixteen (16)
passes, and after the Second Must Take Commencement Date, the number of
unreserved parking passes shall be increased by an additional fifty-nine (59)
passes [total increase of 75 passes]. The use of such additional passes shall
be subject to the terms of the Original Lease, including without limitation,
Articles 1.I and 23 of the Original Lease.

         10. "AS-IS." (a) Except as provided in Section 10(b) below, and
except for any latent defects and minor punch-list items, the Expansion
Premises shall be delivered to Tenant as of the Expansion Premises
Commencement Date in its "as-is, where-is condition", with all faults.

         (b) In addition to the Tenant Improvement Allowance under Exhibit
"D" of the Original Lease, Tenant shall be entitled to a one-time tenant
improvement allowance (the "Expansion Allowance") in the amount of
$383,275.00 (based on $25.00 per usable square foot of the Expansion
Premises) for the costs relating to the initial design and construction of
Tenant's improvements which are permanently affixed to the Expansion Premises
(the "Expansion Improvements"). The Expansion Improvements shall include,
without limitation, the installation of (i) the Network Room (defined in
paragraph 12 below) in the Initial Expansion Premises, and (ii) the HVAC Unit
(defined in paragraph 12 below). In no event shall Landlord be obligated to
make disbursements pursuant to this provision in a total amount which exceeds
the Expansion Allowance. Subject to the following exceptions, the Work Letter
Agreement attached to the Original Lease shall apply to the construction of
the Expansion Improvements with full force and effect:

             (i) The second sentence of Section 2.1 of the Work Letter
Agreement shall not apply to the construction of the Expansion Improvements;

             (ii) The terms "Tenant Improvement Allowance" and "Tenant

terms are defined above);


                                      -5-

<PAGE>


         (iii) The reference to $3,996.73 in Section 2.2 of the Work Letter
shall be replaced with "$2,299.65";

         (iv) Section 4.1 of the Work Letter shall be modified to provide
that the "Contractor" shall be Silagi Development; and

         (v) Landlord shall pay Tenant up to an amount equal to (y) the sum
of the Tenant Improvement Allowance plus the Expansion Allowance
(collectively, the "Total Allowance") less (z) the total amount spent for the
costs relating to the initial design and construction of the Tenant
Improvements and Expansion Improvements (the "FF&E Allowance"). The FF&E
Allowance shall be used to compensate Tenant for Tenant's actual
out-of-pocket costs paid to third-parties for (i) the purchase and
installation of any furniture, fixtures and equipment in the Premises, and
(ii) telephone and data cabling installation and hook-up in the Premises.
Such payment shall be made by Landlord to Tenant within a reasonable period
of time following a written request therefor from Tenant to Landlord,
provided that Tenant has performed all of its obligations under the Lease up
to and including the date of the proposed payment, and provided Tenant has
delivered to Landlord invoices from such third-parties covering items
included in Tenant's request for payment. Any such payment by Landlord
hereunder shall be applied against the Total Allowance. Tenant shall be
entitled to a rental credit in the event that the FF&E Allowance exceeds the
actual out-of-pocket costs paid by Tenant in connection with the items
referenced above.

         11. BUILDING SIGNAGE. Subject to the approval of all necessary
governmental or regulatory agencies with jurisdiction over the Project, and
provided (a) Original Tenant directly leases from Landlord and occupies at
least two (2) of the three (3) floors of the Project, and (b) Original Tenant
is not in default under the Lease, after the expiration of applicable notice
and cure periods, Original Tenant (and not any assignee, sublessee, or other
transferee of the Original Tenant's interest in the Lease) shall have the
right to install one (1) sign in the lobby of the Project identifying
Original Tenant (the "Lobby Signage"), the size, location, method of
attachment, design and all other aspects of said signage to be subject to the
approval of Landlord. Original Tenant shall be solely responsible for all
costs incurred in connection with the purchase and installation of said Lobby
Signage. Original Tenant shall furthermore be solely responsible for all
costs associated with maintaining, operating or otherwise repairing said
Lobby Signage. At the expiration or earlier termination of the Lease, or in
the event the conditions precedent to the grant of said Lobby Signage to
Original Tenant are no longer satisfied, Original Tenant shall remove said
signage, at its sole expense, and repair any damage to the Project or
otherwise caused by said removal.

         12. PROJECT SERVICES. Landlord hereby acknowledges and agrees that
Tenant, at Tenant's expense, is installing a computer network room ("Network
Room") within the Initial Expansion Premises that will house computers and
other equipment that will demand a greater use of electric current than
normal, and Landlord hereby consents to the placement of such equipment
within the Initial Expansion Premises. All plans and specifications relating
to the Network Room shall be subject to approval by Landlord and the Network
Room shall be


                                     -6-

<PAGE>



constructed in accordance with the terms of the Work Letter Agreement, as
modified by paragraph 10 above.

         The parties hereby acknowledge and agree that the Network Room will
be separately metered, at Tenant's expense, and that Tenant shall pay the
costs of any electric current consumed therein. The parties also hereby
acknowledge and agree that the Network Room and Tenant's customer care area
will be monitored and cooled by a separate air conditioning and heating
package unit, (the "HVAC Unit"), the operating costs of which shall be
separately metered and paid by Tenant.

         13. ORIGINAL LEASE DELETION. Article 32 of the Original Lease is
hereby deleted in its entirety and shall be of no further force and effect.

         14. ASSIGNMENT/SUBLETTING. The last paragraph of Article 15 of the
Original Lease is hereby amended to provide that Landlord shall have no right
to terminate the Lease pursuant to said paragraph as a result of any request
by Tenant to sublease all or any portion of the Second Must Take Space for a
term not exceeding the end of the eighteen (18) month period immediately
following the date of this Amendment.

         15. ESTOPPEL. Tenant warrants, represents and certifies to Landlord,
to the best of Tenant's actual knowledge, that as of the date of this
Amendment, (a) Landlord is not in default under the Lease, and (b) Tenant
does not have any defenses or offsets to payment of rent and performance of
its obligations under the Lease as and when same becomes due.

         16. BROKERS. Tenant and Landlord each represents and warrants to the
other that, other than Grubb & Ellis, it has not dealt with any other broker
with respect to this Amendment. If Tenant or Landlord has dealt with any
other broker, Tenant or Landlord, as applicable, shall be solely responsible
for the payment of any fees due said person or firm and Tenant or Landlord,
as applicable, shall protect, indemnify, hold harmless and defend the other
from any liability in respect thereto.

         17. AUTHORITY. Tenant has full power and authority to enter into
this Amendment and the person signing on behalf of Tenant has been fully
authorized to do so by all necessary corporate or partnership action on the
part of Tenant.

         18. LEASE IN FULL FORCE. Except for those provisions which are
inconsistent with this Amendment and those terms, covenants and conditions
for which performance has heretofore been completed, all other terms,
covenants and conditions of the Original Lease shall remain in full force and
effect and Tenant hereby ratifies the Original Lease, as amended hereby.

         IN WITNESS WHEREOF, this Amendment is executed as of the date first
written above.

                  (a)      Termination "for cause" is defined as follows: the
                           Company terminates Employee's employment with the
                           Company (1) if Employee is convicted of a felony
                           or commits an act of moral turpitude, in either
                           case which adversely impacts the Company, (2) if
                           Employee materially breaches the Company's
                           Confidentiality and Proprietary Agreement, or (3)
                           if Employee fails, after receipt of detailed
                           written notice and after receiving a period of at
                           least thirty (30) days following such notice to
                           cure such failure,  to use his reasonable good
                           faith efforts to follow the direction of the
                           Company's Board of Directors and to perform his
                           obligations hereunder.

                  (b)      The Company may terminate this Agreement for any
                           of the reasons stated in Section 4.1(a) by giving
                           written notice to Employee without prejudice

                                       2

<PAGE>

                           to any other remedy to which the Company may be
                           entitled.  The notice of termination shall specify
                           the grounds for termination.  If Employee's
                           employment hereunder is terminated "for cause"
                           pursuant to this Section 4.1, Employee shall be
                           entitled to receive hereunder his accrued but
                           unpaid Base Salary and vacation pay through the
                           date of termination, and reimbursement for any
                           expenses as set forth in Section 3.5, through the
                           date of termination, but shall not be entitled to
                           receive any unpaid portion of the Annual Bonus or
                           any other amount.

         4.2      TERMINATION WITHOUT CAUSE. If Employee's employment is
                  terminated without "cause" as defined in Section 4.1(a), or if
                  Employee is Involuntarily Terminated (as defined below), the
                  Company (or its successor, as the case may be) shall pay to
                  Employee (i) any accrued but unpaid Base Salary and vacation
                  through the date of termination, (ii) reimbursement for any
                  expenses as set forth in Section 3.5, through the date of
                  termination, (iii) Employee's Annual Bonus, prorated through
                  the date of termination, and (iv) a severance payment in an
                  amount equal to Two Hundred Seventy Thousand Dollars
                  ($270,000.00), payable in one lump sum, subject to withholding
                  as may be required by law. In addition, if Employee's
                  employment is terminated without cause (other than if Employee
                  is Involuntarily Terminated) or if Employee's employment is
                  terminated due to death or permanent disability, Employee will
                  be credited with an additional twelve (12) months of service
                  toward vesting in the Option shares in addition to the service
                  he has accrued toward vesting through the date of termination.
                  If Employee is Involuntarily Terminated, vesting of the Option
                  shares will be accelerated in full; provided, however,
                  Employee will only vest in 75% of the Option shares if the
                  Corporate Transaction takes place in the first nine months
                  following the date of commencement of Employee's employment.

                  As used in this Section 4.2, Employee shall be deemed
                  "Involuntarily Terminated" if (i) the Company or any successor
                  to the Company terminates Employee's employment without cause
                  in connection with or following a Corporate Transaction (as
                  defined in the Company's stock option plan); or (ii) in
                  connection with or following a Corporate Transaction there is
                  (a) a decrease in Employee's title or responsibilities (it
                  being deemed to be a decrease in title and/or responsibilities
                  if Employee is not offered the position of Senior Vice
                  President and General Counsel of the Company or its successor
                  as well as the acquiring and ultimate parent entity, if any,
                  following the Corporate Transaction), (b) a decrease in pay
                  and/or benefits from those provided by the Company immediately
                  prior to the Corporate Transaction or (c) a requirement that
                  Employee re-locate out of the greater Los Angeles metropolitan
                  area.

5.                ASSIGNMENT. Neither the Company nor Employee may assign this
                  Agreement or any rights or obligations hereunder. This
                  Agreement will be binding upon the Company and its successors
                  and assigns. In the event of a Corporate Transaction,

                                       3

                  the Company shall cause this Agreement to be assumed by the
                  Company's successor as well as any acquiring or ultimate
                  parent entity, if any, following any Corporate Transaction.

6.       MISCELLANEOUS.

         6.1      This Agreement supersedes any and all other agreements, either
                  oral or in writing, between the parties hereto with respect to

                  Confidentiality and Proprietary Agreement, and constitutes the
                  entire agreement between the Company and the Employee with
                  respect to its subject matter.

                  hereto and which is authorized by the Company's Board of
                  Directors.

                  California, without giving effect to its conflicts-of-law
                  principles.

         6.4      In the event that any provision of this Agreement is
                  determined to be illegal, invalid or void for any reason, the

90210 ("Employee").

1.       EMPLOYMENT.

         1.1      The Company hereby agrees to employ Employee, and Employee
                  hereby accepts such employment, on the terms and conditions
                  set forth herein, commencing March 20, 1999 (the "Effective
                  Date"), and continuing through March 19, 2003 (the "Term"),
                  unless terminated earlier as provided in Section 4 below.

2.       DUTIES OF EMPLOYEE.

         2.1      Employee shall serve as the Chief Executive Officer and
                  Chairman of the Company. In this capacity, Employee shall
                  perform such customary, appropriate and reasonable executive
                  duties as are usually performed by the Chief Executive Officer
                  and Chairman, including such duties as are delegated to him
                  from time to time by the Board of Directors of the Company
                  (the "Board"). Employee shall report directly to the Company's
                  Board.

         2.2      Employee agrees to devote Employee's good faith, full time,
                  attention, skill and efforts to the performance of his duties
                  for the Company during the Term; provided, however, that the
                  Company acknowledges that Employee has certain
                  responsibilities to and involvement with other entities and
                  agrees to allow Employee to continue his involvement with such
                  entities in the following manner without in anyway
                  jeopardizing his employment with the Company:

                  (a)      SILICON GRAPHICS. Employee has certain
                           responsibilities to Silicon Graphics that will
                           require Employee's attention for several days a month
                           through June 30, 1999;

                  (b)      CALIFORNIA CONCEPTS. Employee has certain
                           responsibilities to California Concepts that will
                           require his attention through December 31, 1999. In
                           addition, Employee may serve on California Concept's
                           Board of Directors for an indefinite period, once
                           such a Board is established; and

                  (c)      PATENT SERVICE CORPORATION AND CLUB MOM, INC.
                           Employee has an ownership interest in the Patent
                           Service Corporation and Club Mom, Inc. Employee shall
                           be allowed to continue his involvement with these
                           organizations, both as a partial owner, and as his
                           services are needed to promote the organizations'
                           interests.

                  In addition to the organizations specifically referenced
                  above, Employee currently sits on two academic boards which
                  only require a minimal time commitment but which will be
                  ongoing into the future. Moreover, this Agreement shall not be
                  interpreted to prohibit Employee from making passive personal
                  investments if those activities do not materially interfere
                  with the services required under this Agreement.

3.       COMPENSATION AND OTHER BENEFITS.

         3.1      BASE SALARY. During the first two years of the Term, the
                  Company shall pay to Employee a base salary of Two Hundred
                  Thousand Dollars ($200,000) per calendar year (the "Base
                  Salary"), prorated for any portion thereof during the first
                  two years of the Term, payable at the rate of Sixteen Thousand
                  Six Hundred Sixty-Six and 67/100 Dollars ($16,666.67) per
                  month, with payments to be made in accordance with the
                  Company's standard payment policy and subject to such
                  withholding as may be required by law.

         3.2      BONUS. During the first two years of the Term, the Company
                  shall also pay to Employee a cash bonus in a gross amount
                  equal to Two Hundred Thousand Dollars ($200,000) per calendar
                  year (the "Annual Bonus"), less withholding required by law,
                  one quarter of which is payable on each of the last business
                  days of March, June, September and December of each year
                  during the first two years of the Term. The first payment of
                  this bonus is due to Employee on March 31, 1999. Employee
                  shall not be eligible to receive any unpaid Annual Bonus if
                  his employment hereunder is terminated pursuant to either
                  Section 4.1, or if Employee voluntarily resigns.

         3.3      SIGNING BONUS. The Company shall also pay to Employee a cash
                  bonus of Three Hundred Thousand Dollars ($300,000), less
                  withholding required by law, in one lump sum on January 1,
                  2000, provided, such bonus shall only be paid if Employee is
                  employed by the Company on such date.

         3.4      NEGOTIATION OF COMPENSATION TERMS FOR FINAL TWO YEARS OF
                  EMPLOYMENT AGREEMENT. At one month prior to the end of his
                  second year of employment, I.E., by February 19, 2001, the
                  Company and Employee shall negotiate in good faith for a
                  period of 30 days regarding the terms of Employee's
                  compensation package for the final two years of the Employment
                  Term. The terms of the compensation package shall include
                  equity and cash compensation (salary and bonus) and benefits,
                  and such terms shall be at least commensurate with the terms
                  of compensation packages of similarly situated executives
                  (I.E., Chairmen and Chief Executive Officers) of similar
                  companies. In the event the Company and Employee do not reach
                  agreement on the terms of such compensation package within the
                  30-day period, this Employment Agreement will terminate
                  effective as of March 20, 2001. Furthermore, if this
                  Employment Agreement is so terminated and Company did not
                  offer Employee, during such negotiations, an annual base
                  salary in an amount greater than Two Hundred Thousand Dollars
                  ($200,000) and a guaranteed annual bonus in an amount greater
                  than Two Hundred Thousand

                  Dollars ($200,000), payable quarterly, then Employee shall
                  be entitled to receive the severance payment and other
                  benefits set forth in Section 4.3 below.

         3.5      VACATION. Employee shall be entitled to a minimum of four (4)
                  weeks paid vacation per year.

         3.6      OTHER BENEFITS. During the Term, Employee shall be entitled to
                  participate in all group life, health, medical, dental or
                  disability insurance or other employee, health and welfare
                  benefits made available generally to other executives of the
                  Company, when and as Employee becomes eligible therefor. If
                  Employee elects to participate in any of such plans,
                  Employee's portion of the premium(s) will be deducted from
                  Employee's paycheck.

         3.7      BUSINESS EXPENSES. The Company shall promptly reimburse
                  Employee for all reasonable and necessary business expenses
                  incurred by Employee in connection with the business of the
                  Company and the performance of his duties under this
                  Agreement, subject to Employee providing the Company with
                  reasonable documentation thereof.

         3.8      OPTION GRANT. Employee shall be granted a stock option (the
                  "Option") under the Company's 1999 Stock Option/Stock
                  Incentive Plan, for 4,190,922 shares of the Company's Common
                  Stock, at an exercise price of $0.15 per share. Such stock

                  Promissory Note executed by Employee in favor of the Company

4.       TERMINATION.

         4.1      TERMINATION FOR CAUSE.

                  (a)      Termination "for cause" is defined as follows: (1) if
                           Employee is convicted of a felony, including any act
                           of moral turpitude, or (2) if Employee materially
                           breaches the Company's Confidentiality and
                           Proprietary Agreement.

                  (b)      The Company may terminate this Agreement immediately
                           for any of the reasons stated in Section 4.1(a) by
                           giving written notice to Employee without prejudice
                           to any other remedy to which the Company may be
                           entitled. The notice of termination shall specify the
                           grounds for termination. If Employee's employment
                           hereunder is terminated "for cause" pursuant to this
                           Section 4.1, Employee shall be entitled to receive
                           hereunder his accrued but unpaid Base Salary and
                           vacation pay through the date of termination, and
                           reimbursement for any expenses as set forth in
                           Section 3.5, through the date of termination, but
                           shall not be entitled to receive any unpaid portion
                           of the Annual Bonus or any other amount.

         4.2      TERMINATION WITHOUT CAUSE. If Employee's employment is
                  terminated without "cause" as defined in Section 4.1(a), he
                  will be eligible for the severance benefits set forth in
                  Section 4.3.

         4.3      SEVERANCE PAYMENTS AND OTHER BENEFITS UPON TERMINATION WITHOUT
                  CAUSE OR INVOLUNTARY TERMINATION. If the Company terminates
                  Employee's employment hereunder without cause, or if Employee
                  is Involuntarily Terminated, the Company (or its successor, as
                  the case may be) shall pay to Employee (i) any accrued but
                  unpaid Base Salary and vacation through the date of
                  termination, (ii) reimbursement for any expenses as set forth
                  in Section 3.5, through the date of termination, (iii)
                  Employee's Annual Bonus, prorated through the date of
                  termination, and (iv) a severance payment in an amount equal
                  to One Million Dollars ($1,000,000.00), payable in one lump
                  sum, subject to withholding as may be required by law. In
                  addition, Employee shall be entitled to accelerated vesting of
                  the Option, as set forth in the Notice. As used in this
                  Section 4.3, "Involuntarily Terminated" shall mean (a)
                  Employee's voluntary resignation following a Corporate
                  Transaction in which Employee is not offered a position of
                  comparable pay and responsibilities in the greater Los
                  Angeles, California metropolitan area, or (b) where, within
                  twelve (12) months of a Corporate Transaction, Employee
                  voluntarily resigns following either (X) a reduction of
                  Employee's salary or (Y) a material change of Employee's
                  responsibilities. As used in this Section 4.3, "Corporate
                  Transaction" shall mean (i) a merger or consolidation or other
                  reorganization or transaction in which securities possessing
                  more than fifty percent (50%) of the total combined voting
                  power of the Company's outstanding securities are transferred
                  or issued to a person or persons different from the persons
                  holding those securities immediately prior to such
                  transaction, or (ii) the sale, transfer or other disposition
                  of all or substantially all

                                       4

<PAGE>

                  of the Company's assets in complete liquidation or
                  dissolution of the Company. As used in this Section 4.3, a
                  "material change" in Employee's responsibilities includes
                  any decrease in Employee's compensation or benefits or any
                  material change in Employee's job duties, title, or
                  location of employment (out of the greater Los Angeles,
                  California metropolitan area).

5.       EXCISE TAX. If any payments or transfers of property to be made to
         Employee hereunder are subject, in whole or in part, to the excise tax
         imposed by Section 4999 of the Internal Revenue Code of 1986, ("the
         Excise Tax") and application of Section 280G of such Code, can be
         avoided by an appropriate shareholder vote, pursuant to Section
         280G(b)(5)(A) of the Code, the Company and Employee agree that they
         will respectively take all steps necessary or appropriate to obtain a
         favorable shareholder vote to assure that the Excise Tax and the
         provisions of Section 280G are not applicable with respect to such
         compensation.

6.       ASSIGNMENT. Employee may not assign this Agreement or any rights or
         obligations hereunder. The Company may assign this Agreement to any of
         its subsidiaries or affiliates or in connection with any Corporate
         Transaction or reincorporation of the Company.

7.       MISCELLANEOUS.

         7.1      This Agreement supersedes any and all other agreements, either
                  oral or in writing, between the parties hereto with respect to
                  the employment of Employee by the Company and constitutes the
                  entire agreement between the Company and the Employee with
                  respect to its subject matter.

         7.2      This Agreement may not be amended, supplemented, modified or
                  extended, except by written agreement which expressly refers
                  to this Agreement, which is signed by of the parties hereto
                  and which is authorized by the Company's Board of Directors.

         7.3      This Agreement is made in and shall be governed by the laws of
                  California, without giving effect to its conflicts-of-law
                  principles.

         7.4      In the event that any provision of this Agreement is
                  determined to be illegal, invalid or void for any reason, the
                  remaining provisions hereof shall continue in full force and
                  effect.

         7.5      Employee represents and warrants to the Company that there is
                  no restriction or limitation, by reason of any agreement or
                  otherwise, upon Employee's right or ability to enter into this
                  Agreement and fulfill his obligations under this Agreement.

                             STOCK PLEDGE AGREEMENT



                  AGREEMENT made as of this 20th day of March, 1999 by and
between NetZero, Inc., a California corporation (the "Corporation") and Mark
Goldston ("Pledgor").


RECITALS

                  A. In connection with the purchase of 4,190,922 shares of the
Corporation's Common Stock (the "Purchased Shares") on the date of this
Agreement from the Corporation, Pledgor has issued that certain promissory note
(the "Note") dated March 20, 1999 payable to the order of the Corporation in the
principal amount of Six Hundred Twenty-Eight Thousand Six Hundred Thirty-Eight
Dollars and Thirty Cents ($628,638.30).

                  B. Such Note is secured by the Purchased Shares and other
collateral upon the terms set forth in this Agreement.

                  NOW, THEREFORE, it is hereby agreed as follows:

         1.       1.     GRANT OF SECURITY INTEREST. Pledgor hereby grants the
Corporation a security interest in, and assigns, transfers to and pledges with
the Corporation, the following securities and other property (collectively, the
"Collateral"):

                  (i)      (i)     the Purchased Shares delivered to and
         deposited with the Corporation as collateral for the Note;

                  (ii)     (ii)    any and all new, additional or different
         securities or other property subsequently distributed with respect to
         the Purchased Shares which are to be delivered to and deposited with
         the Corporation pursuant to the requirements of Paragraph 3 of this
         Agreement;

                  (iii)    (iii)   any and all other property and money which is
         delivered to or comes into the possession of the Corporation pursuant
         to the terms of this Agreement; and

                  (iv)     (iv)    the proceeds of any sale, exchange or
         disposition of the property and securities described in subparagraphs
         (i), (ii) or (iii) above.

         2.       2.     WARRANTIES. Pledgor hereby warrants that Pledgor is the
owner of the Collateral and has the right to pledge the Collateral and that the
Collateral is free from all liens, adverse claims and other security interests
(other than those created hereby).

                                       1.

<PAGE>

         3.       3.     DUTY TO DELIVER. Any new, additional or different
securities or other property (other than regular cash dividends) which may now
or hereafter become distributable with respect to the Collateral by reason of
(i) any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the Common Stock as a class without
the Corporation's receipt of consideration or (ii) any merger, consolidation or
other reorganization affecting the capital structure of the Corporation shall,
upon receipt by Pledgor, be promptly delivered to and deposited with the
Corporation as part of the Collateral hereunder. Any such securities shall be
accompanied by one or more properly endorsed stock power assignments.

         4.       4.     PAYMENT OF TAXES AND OTHER CHARGES. Pledgor shall pay,
prior to the delinquency date, all taxes, liens, assessments and other charges
against the Collateral, and in the event of Pledgor's failure to do so, the
Corporation may at its election pay any or all of such taxes and other charges
without contesting the validity or legality thereof. The payments so made shall
become part of the indebtedness secured hereunder and until paid shall bear
interest at the minimum per annum rate required to avoid the imputation of
interest income to the Corporation and compensation income to Pledgor under the
federal tax laws.

         5.       5.     SHAREHOLDER RIGHTS. So long as there exists no event of
default under Paragraph 10 of this Agreement, Pledgor may exercise all
shareholder voting rights and be entitled to receive any and all regular cash
dividends paid on the Collateral and all proxy statements and other shareholder
materials pertaining to the Collateral.

         6.       6.     RIGHTS AND POWERS OF CORPORATION. The Corporation may,
without obligation to do so, exercise at any time and from time to time one or
more of the following rights and powers with respect to any or all of the
Collateral:

                  (i)      (i) subject to the applicable limitations of
         Paragraph 9, accept in its discretion other property of Pledgor in
         exchange for all or part of the Collateral and release Collateral to
         Pledgor to the extent necessary to effect such exchange, and in such
         event the other property received in the exchange shall become part of
         the Collateral hereunder;

                  (ii)     (ii)    perform such acts as are necessary to
         preserve and protect the Collateral and the rights, powers and remedies
         granted with respect to such Collateral by this Agreement; and

                  (iii)    (iii)   transfer record ownership of the Collateral
         to the Corporation or its nominee and receive, endorse and give receipt
         for, or collect by legal proceedings or otherwise, dividends or other
         distributions made or paid with respect to the Collateral, PROVIDED AND
         ONLY IF there exists at the time an outstanding event of default under
         Paragraph 10 of this Agreement. Any cash sums which the Corporation may
         so receive shall be applied to the payment of the Note and any other
         indebtedness secured hereunder, in such order of application as the
         Corporation deems appropriate. Any remaining cash shall be paid over to
         Pledgor.

                  Any action by the Corporation pursuant to the provisions of
this Paragraph 6 may be taken without notice to Pledgor. Expenses reasonably
incurred in connection with such action

                                       2.

<PAGE>

shall be payable by Pledgor and form part of the indebtedness secured
hereunder as provided in Paragraph 12.

         7.       7.     CARE OF COLLATERAL. The Corporation shall exercise
reasonable care in the custody and preservation of the Collateral. However, the
Corporation shall have no obligation to (i) initiate any action with respect to,
or otherwise inform Pledgor of, any conversion, call, exchange right, preemptive
right, subscription right, purchase offer or other right or privilege relating
to or affecting the Collateral, (ii) preserve the rights of Pledgor against
adverse claims or protect the Collateral against the possibility of a decline in
market value or (iii) take any action with respect to the Collateral requested
by Pledgor unless the request is made in writing and the Corporation determines
that the requested action will not unreasonably jeopardize the value of the
Collateral as security for the Note and other indebtedness secured hereunder.

                  Subject to the limitations of Paragraph 9, the Corporation may
at any time release and deliver all or part of the Collateral to Pledgor.

         8.       8.     TRANSFER OF COLLATERAL. In connection with the transfer
or assignment of the Note (whether by negotiation, discount or otherwise), the
Corporation may transfer all or any part of the Collateral, and the transferee
shall thereupon succeed to all the rights, powers and remedies granted the
Corporation hereunder with respect to the Collateral so transferred. Upon such
transfer, the Corporation shall be fully discharged from any further
responsibility for the transferred Collateral and all liability for the
Collateral arising after the date of such transfer.

         9.       9.     RELEASE OF COLLATERAL. Provided all indebtedness
secured hereunder (other than payments not yet due and payable under the Note)
shall at the time have been paid in full and there does not otherwise exist any
event of default under Paragraph 10, the Purchased Shares, together with any
additional Collateral which may hereafter be pledged and deposited hereunder,
shall be released from pledge and returned to Pledgor in accordance with the
following provisions:

                  (i)      (i)     Promptly following (a) payment or prepayment
         of principal of the Note, together with payment of all accrued interest
         to date, one or more of the Purchased Shares held as Collateral
         hereunder shall (subject to the applicable limitations of Paragraphs
         9(iii) and 9(v) below) be released to Pledgor or (b) a determination
         that Excess Value exists, one or more of the Purchased Shares held as
         Collateral hereunder shall (subject to the applicable limitations of
         Paragraphs 9(iii) and 9(v) below) be released to Pledgor; provided that
         if any Purchased Shares are released pursuant to the immediately
         preceding clause and if the fair market value of the Common Stock and
         all other Collateral which would otherwise remain in pledge hereunder
         after such release at any time falls below one hundred and fifty
         percent (150%) of the unpaid principal and accrued interest under the
         Note, Pledgor shall contribute additional collateral hereunder to raise
         such fair market value of the Purchased Shares and all other Collateral
         in pledge up to such 150% level; provided, further, that in no event
         shall Pledgor be required to make any additional contributions
         hereunder in any amount greater than the amount which the fair market
         value of that the original number of Purchased Shares would represent
         as of the date of such contribution. The number of shares to be so
         released shall

                                       3.

<PAGE>

         be equal to the number obtained, as the case may be, by (x)
         multiplying (i) the total number of Purchased Shares held under this
         Agreement at the time of the payment or prepayment, by (ii) a
         fraction, the numerator of which shall be the amount of the
         principal paid or prepaid and the denominator of which shall be the
         unpaid principal balance of the Note immediately prior to such
         payment or prepayment, or (y) multiplying (i) the total number of
         Purchased Shares held under this Agreement at the time of the
         payment or prepayment, by (ii) a fraction, the numerator of which
         shall be the Excess Value and the denominator of which shall be the
         fair market value of the Purchased Shares and all other Collateral
         held in pledge hereunder immediately prior to any such release. In
         no event, however, shall any fractional shares be released. For
         purposes of this Agreement, "Excess Value" shall mean the excess
         amount, if any, that the fair market value of the Purchased Shares
         and Collateral then held in pledge is over 150% of the total unpaid
         principal and accrued interest of the Note, as such foregoing
         amounts are determined each time that Optionee requests a release of
         shares from pledge.

                  (ii)     (ii)    Any additional Collateral which may hereafter
         be pledged and deposited with the Corporation (pursuant to the
         requirements of Paragraph 3) with respect to the Purchased Shares shall
         be released at the same time the particular shares of Common Stock to
         which the additional Collateral relates are to be released in
         accordance with the applicable provisions of Paragraph 9(i).

                  (iii)    (iii)   Under no circumstances, however, shall any
         Purchased Shares or any other Collateral be released if previously
         applied to the payment of any indebtedness secured hereunder. In
         addition, in no event shall any Purchased Shares or other Collateral be
         released pursuant to the provisions of Paragraph 9(i) or 9(ii) if, and
         to the extent, the fair market value of the Common Stock and all other
         Collateral which would otherwise remain in pledge hereunder after such
         release were effected would be less than the unpaid principal and
         accrued interest under the Note.

                  (iv)     (iv)    For all valuation purposes under this
         Agreement, the fair market value per share of Common Stock on any
         relevant date shall be determined in accordance with the following
         provisions:

                           (A)      (A)      If the Common Stock is at the time
                  traded on the Nasdaq National Market, the fair market value
                  shall be the closing selling price per share of Common Stock
                  on the date in question, as such prices are reported by the
                  National Association of Securities Dealers on its Nasdaq
                  system or any successor system. If there is no reported
                  closing selling price for the Common Stock on the date in
                  question, then the closing selling price on the last preceding
                  date for which such quotation exists shall be determinative of
                  fair market value.

                           (B)      (B)      If the Common Stock is at the time
                  listed on the New York Stock Exchange or any other securities
                  exchange, then the fair market value shall be the closing
                  selling price per share of Common Stock on the date in
                  question on the securities exchange serving as the primary
                  market for the Common Stock, as such price is officially
                  quoted in the composite tape of transactions on such exchange.
                  If there is no reported sale of Common Stock on such exchange
                  on the date in question, then the fair market value shall be
                  the

                                       4.

<PAGE>

                  closing selling price on the exchange on the last preceding
                  date for which such quotation exists.

                           (C)      (C)      If the Common Stock is at the time
                  neither listed on any securities exchange nor traded on the
                  Nasdaq National Market, the fair market value shall be
                  determined by the Corporation's Board of Directors after
                  taking into account such factors as the Board shall deem
                  appropriate; provided, however that in the event Pledgor
                  disagrees with the Board's determination, Pledgor and the
                  Board shall agree in good faith on such valuation. If the
                  Pledgor and Corporation do not so agree, Pledgor shall have
                  the right, but not more often than once every six (6) months
                  on a rolling basis, to require the appraisal of the
                  Corporation. If Corporation and Pledgor cannot promptly agree
                  upon an independent, experienced appraiser who is a member of
                  a recognized professional association of business appraisers
                  (an "appraiser"), then each of the Corporation and Pledgor
                  shall appoint such independent, experienced appraiser who
                  shall determine the value of the Common Stock. If the higher
                  of the two appraisals is not more than 10 percent more than
                  the lower of the appraisals, the fair market value shall be
                  the average of the two appraisals (which determination shall
                  be final and binding on the parties and enforceable in any
                  court of competent jurisdiction); provided that if the two
                  appraisals are more than 10 percent apart the two appraisers
                  shall appoint a third appraiser who shall determine the value
                  of the Common Stock, which determination shall be final and
                  binding on the parties and enforceable in any court of
                  competent jurisdiction. All costs of such appraisal shall be
                  equally shared by the Corporation and Employee.

                  (v)      (v)     In the event the Collateral becomes in whole
         or in part comprised of "margin securities" within the meaning of
         Section 207.2(i) of Regulation G of the Federal Reserve Board, then no
         Collateral shall thereafter be substituted for any Collateral under the
         provisions of Paragraph 6(i) or be released under Paragraph 9(i) or
         (ii), unless there is compliance with each of the following additional
         requirements:

                           (A)      (A)      The substitution or release must
                  not increase the amount by which the indebtedness secured
                  hereunder at the time of such substitution or release exceeds
                  the maximum loan value (as defined below) of the Collateral
                  immediately prior to such substitution or release.

                           (B)      (B)      The substitution or release must
                  not cause the amount of indebtedness secured hereunder at the
                  time of such substitution or release to exceed the maximum
                  loan value of the Collateral remaining after such substitution
                  or release is effected.

                           (C)      (C)      For purposes of this Paragraph
                  9(v), the maximum loan value of each item of Collateral shall
                  be determined on the day the substitution or release is to be
                  effected and shall, in the case of the shares of Common Stock
                  and any additional Collateral (other than margin securities),
                  equal the good faith loan value thereof (as defined in Section
                  207.2(e)(1) of Regulation G) and shall, in the case of all
                  margin securities (other than the Common Stock), equal fifty
                  percent (50%) of the current market value of such securities.

                                       5.

         10.      10. EVENTS OF DEFAULT. The occurrence of one or more of the
following events shall constitute an event of default under this Agreement:

                  (i)      (i)     the failure of Pledgor to pay, when due under
         the Note, any installment of principal or accrued interest after any
         grace period set forth in the Note has expired, if any; or

                  (ii)     (ii)    the wilful failure of Pledgor to perform any
         material obligation imposed upon Pledgor by reason of this Agreement
         within 30 days following written notice to Pledgor detailing such
         failure; or

                  (iii)    (iii)   the material breach of any warranty of
         Pledgor contained in Paragraph 2 of this Agreement.

                  Upon the occurrence of any such event of default, the
Corporation may, at its election, declare the Note and all other indebtedness
secured hereunder to become immediately due and payable and may exercise any or
all of the rights and remedies granted to a secured party under the provisions
of the California Uniform Commercial Code (as now or hereafter in effect),
including (without limitation) the power to dispose of the Collateral by public
or private sale or to accept the Collateral in full payment of the Note and all
other indebtedness secured hereunder.

                  Any proceeds realized from the disposition of the Collateral
pursuant to the foregoing power of sale shall be applied first to the payment of
reasonable expenses incurred by the Corporation in connection with the
disposition and then to the payment of the Note and finally to any other
indebtedness secured hereunder. Any surplus proceeds shall be paid over to
Pledgor. However, in the event such proceeds prove insufficient to satisfy all
obligations of Pledgor under the Note which are recourse to Pledgor, then
Pledgor shall remain personally liable for the remaining obligations under the
Note which are recourse to Pledgor.

         11.      11.    OTHER REMEDIES. The rights, powers and remedies granted
to the Corporation pursuant to the provisions of this Agreement shall be in
addition to all rights, powers and remedies granted to the Corporation under any
statute or rule of law. Any forbearance, failure or delay by the Corporation in
exercising any right, power or remedy under this Agreement shall not be deemed
to be a waiver of such right, power or remedy. Any single or partial exercise of
any right, power or remedy under this Agreement shall not preclude the further
exercise thereof, and every right, power and remedy of the Corporation under
this Agreement shall continue in full force and effect unless such right, power
or remedy is specifically waived by an instrument executed by the Corporation.

         12.      12.    COSTS AND EXPENSES. All costs and expenses (including
reasonable attorneys fees) incurred by the Corporation in the exercise or
enforcement of any right, power or remedy granted it under this Agreement shall
become part of the indebtedness secured hereunder and shall constitute a
personal liability of Pledgor payable immediately upon demand and bearing
interest until paid at the minimum per annum rate required to avoid the
imputation of interest income to the Corporation and compensation income to
Pledgor under the federal tax laws.

                                       6.

         13.      13.    APPLICABLE LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of California without resort
to that State's conflict-of-laws rules.

         14.      14.    SUCCESSORS. This Agreement shall be binding upon the
Corporation and its successors and assigns and upon Pledgor and the executors,
heirs and legatees of Pledgor's estate.

         15.      15.    SEVERABILITY. If any provision of this Agreement is
held to be invalid under applicable law, then such provision shall be
ineffective only to the extent of such invalidity, and neither the remainder of
such provision nor any other provisions of this Agreement shall be affected
thereby.

                  IN WITNESS WHEREOF, this Agreement has been executed by
Pledgor and the Corporation on this 20th day of March, 1999.

         THIS AMENDMENT TO STOCK PLEDGE AGREEMENT (this "Amendment") is dated as

         In consideration of good and valuable consideration, the receipt of
which is hereby acknowledged, the parties hereto agree as follows:

and restated in its entirety as follows:

                  Corporation as collateral for the Note;

                  (ii) 36,232 shares of the Corporation's Series D Preferred
                  Stock (the "Pledged Series D Stock");

                  (iii) any and all new, additional or different securities or
                  other property subsequently distributed with respect to the
                  Purchased Shares or the Pledged Series D Stock which are to be
                  delivered to and deposited with the Corporation pursuant to
                  the requirements of Paragraph 3 of this Agreement;

                  (iv) any and all other property and money which is delivered
                  to or comes into the possession of the Corporation pursuant to

                  (v) the proceeds of any sale, exchange or disposition of the
                  property and securities described in subparagraphs (i), (ii),
                  (iii) or (iv) above."

         2. Paragraphs 9(i) through (iv) of the Stock Pledge Agreement are
hereby amended and restated in their entirety as follows:

                  "RELEASE OF COLLATERAL. Provided all indebtedness secured
                  hereunder (other than payments not yet due and payable under
                  the Note) shall at the time have been paid in full and there
                  does not otherwise exist any event of default under Paragraph
                  10, the Purchased Shares and the Pledged Series

                                       1.

<PAGE>

                  D Stock, together with any additional Collateral which may
                  hereafter be pledged and deposited hereunder, shall be
                  released from pledge and returned to Pledgor in accordance
                  with the following provisions:

                  (i) Promptly following (a) payment or prepayment of principal
                  of the Note, together with payment of all accrued interest to
                  date, one or more of the Purchased Shares or the Pledged
                  Series D Stock held as Collateral hereunder shall (subject to
                  the applicable limitations of Paragraphs 9(iii), (v) and (vi)
                  below) be released to Pledgor or (b) a determination that
                  Excess Value exists, one or more of the Purchased Shares or
                  the Pledged Series D Stock held as Collateral hereunder shall
                  (subject to the applicable limitations of Paragraphs 9(iii),
                  (v) and (vi) below) be released to Pledgor; provided that if
                  any Purchased Shares or Pledged Series D Stock are released
                  pursuant to the immediately preceding clause and if the fair
                  market value of the Purchased Shares, Pledged Series D Stock
                  and all other Collateral which would otherwise remain in
                  pledge hereunder after such release at any time falls below
                  one hundred and fifty percent (150%) of the unpaid principal
                  and accrued interest under the Note, Pledgor shall contribute
                  additional collateral hereunder to raise such fair market
                  value of the Purchased Shares, the Pledged Series D Stock, and
                  all other Collateral in pledge up to such 150% level;
                  provided, further, that in no event shall Pledgor be required
                  to make any additional contributions hereunder in any amount
                  greater than the amount which the fair market value of the
                  original number of Purchased Shares would represent as of the
                  date of such contribution. The number of shares to be so
                  released shall be equal to the number obtained, as the case
                  may be, by (x) multiplying (i) the total number of shares of
                  Common Stock represented by the Purchased Shares and the
                  Pledged Series D Stock (on an as-converted basis) held under
                  this Agreement at the time of the payment or prepayment, by
                  (ii) a fraction, the numerator of which shall be the amount of
                  the principal paid or prepaid and the denominator of which
                  shall be the unpaid principal balance of the Note immediately
                  prior to such payment or prepayment, or (y) multiplying (i)
                  the total number of shares of Common Stock represented by the
                  Purchased Shares and the Pledged Series D Stock (on an
                  as-converted basis) held under this Agreement at the time of
                  the payment or prepayment, by (ii) a fraction, the numerator
                  of which shall be the Excess Value and the denominator of
                  which shall be the fair market value of the Purchased Shares,
                  the Pledged Series D Stock and all other Collateral held in
                  pledge hereunder immediately prior to any such release. In no
                  event, however, shall any fractional shares be released. For
                  purposes of this Agreement, "Excess Value" shall mean the
                  excess amount, if any, that the fair market value of the
                  Purchased Shares, the Pledged Series D Stock and Collateral
                  then held in pledge is over 150% of the total unpaid principal
                  and accrued interest of the Note, as such foregoing amounts
                  are determined each time that Optionee requests a release of
                  shares from pledge.

                  (ii) Any additional Collateral which may hereafter be pledged
                  and deposited with the Corporation (pursuant to the
                  requirements of Paragraph 3) with respect to the Purchased
                  Shares or the Pledged Series D Stock shall be released at the
                  same time the particular shares of Purchased Shares or Pledged
                  Series D Stock to which the additional Collateral relates are
                  to be released in accordance with the applicable provisions of
                  Paragraph 9(i).

                  (iii) Under no circumstances, however, shall any Purchased
                  Shares, Pledged Series D Stock or any other Collateral be
                  released if previously applied to the payment of any
                  indebtedness secured hereunder. In addition, in no event shall
                  any Purchased Shares, Pledged Series D Stock, or other
                  Collateral be released pursuant to the provisions of Paragraph
                  9(i) or 9(ii) if, and to the extent, the fair market value of
                  the Purchased Shares, Pledged Series D Stock and all other
                  Collateral which would otherwise remain in pledge hereunder
                  after such release were effected would be less than the unpaid
                  principal and accrued interest under the Note.

                  (iv) For all valuation purposes under this Agreement, the fair
                  market value per share of Purchased Shares and/or Pledged
                  Series D Stock on any relevant date shall be determined in
                  accordance with the following provisions:

                  (A) If the security is at the time traded on the Nasdaq
                  National Market, the fair market value shall be the closing
                  selling price per share of such security on the date in
                  question, as such prices are reported by the National
                  Association of Securities Dealers on its Nasdaq system or any
                  successor system. If there is no reported closing selling
                  price for the security on the date in question, then the
                  closing selling price on the last preceding date for which
                  such quotation exists shall be determinative of fair market
                  value.

                  (B) If the security is at the time listed on the New York
                  Stock Exchange or any other securities exchange, then the fair
                  market value shall be the closing selling price per share of
                  such security on the date in question on the securities
                  exchange serving as the primary market for such security, as
                  such price is officially quoted in the composite tape of
                  transactions on such exchange. If there is no reported sale of
                  such security on such exchange on the date in question, then
                  the fair market value shall be the closing selling price on
                  the exchange on the last preceding date for which such
                  quotation exists.

                  (C) If the security is at the time neither listed on any
                  securities exchange nor traded on the Nasdaq National Market,
                  the fair market value shall be determined by the Corporation's
                  Board of Directors after taking into account such factors as
                  the Board shall deem appropriate; provided, however that in
                  the event Pledgor disagrees with the Board's determination,
                  Pledgor and the Board shall agree in good faith on such
                  valuation. If the Pledgor and Corporation do not so agree,
                  Pledgor shall

                                       3.

<PAGE>

                  have the right, but not more often than once every six (6)
                  months on a rolling basis, to require the appraisal of the
                  Corporation. If the Corporation and Pledgor cannot promptly
                  agree upon an independent, experienced appraiser who is a
                  member of a recognized professional association of business
                  appraisers (an "appraiser"), then each of the Corporation
                  and Pledgor shall appoint such independent, experienced
                  appraiser who shall determine the value of the security. If
                  the higher of the two appraisals is not more than 10
                  percent more than the lower of the appraisals, the fair
                  market value shall be the average of the two appraisals
                  (which determination shall be final and binding on the
                  parties and enforceable in any court of competent
                  jurisdiction); provided that if the two appraisals are more
                  than 10 percent apart the two appraisers shall appoint a
                  third appraiser who shall determine the value of the
                  security, which determination shall be final and binding on
                  the parties and enforceable in any court of competent
                  jurisdiction. All costs of such appraisal shall be equally
                  shared by the Corporation and Employee."

         3. Paragraph 9(vi) is hereby added to the Stock Pledge Agreement as
follows:

                  "(vi) If any Purchased Shares or Pledged Series D Stock are to
                  be released from their pledge hereunder pursuant to Paragraph
                  9(i), the order of such release shall be Purchased Shares
                  first, and then Pledged Series D Stock. No shares of Pledged
                  Series D Stock shall be released from the pledge hereunder
                  until all Purchased Shares have been released from their
                  pledge hereunder."

         4. In all other respects, the Stock Pledge Agreement shall remain
unchanged and in full force and effect in accordance with the terms thereof.

                  IN WITNESS WHEREOF, each of the parties hereto has executed
this Amendment as of the date first above written.

                  in the Company's next round of financing, if and when such
                  stock is issued, at the same price per share paid by other
                  purchasers participating in such financing.

                                    follows: the Company terminates Employee's
                                    employment with the Company (1) if Employee
                                    is convicted of a felony or commits an act
                                    of moral turpitude, in either case which
                                    adversely impacts the Company, (2) if
                                    Employee materially breaches the Company's
                                    Confidentiality and Proprietary Agreement,
                                    or (3) if Employee fails, after receipt of
                                    detailed written notice and after receiving
                                    a period of at least thirty (30) days
                                    following such notice to cure such failure,
                                    to use his reasonable good faith efforts to
                                    follow the direction of the Company's Board
                                    of Directors and to perform his obligations
                                    hereunder.

                  (b)      The Company may terminate this Agreement for any of
                           the reasons stated in Section 4.1(a) by giving
                           written notice to Employee without prejudice to any
                           other remedy to which the Company may be entitled.
                           The notice of termination shall specify the grounds
                           for termination. If Employee's employment hereunder
                           is terminated "for cause" pursuant to this Section
                           4.1, Employee shall be entitled to receive hereunder
                           his accrued but unpaid Base Salary and vacation pay
                           through the date of termination, and reimbursement
                           for any expenses as set forth in Section 3.5, through
                           the date of termination, but shall not be entitled to
                           receive any unpaid portion of the Annual Bonus or any
                           other amount.

         4.2      TERMINATION WITHOUT CAUSE. If Employee's employment is
                  terminated without "cause" as defined in Section 4.1(a), or if
                  Employee is Involuntarily Terminated (as defined below), the
                  Company (or its successor, as the case may be) shall pay to
                  Employee (i) any accrued but unpaid Base Salary and vacation
                  through the date of termination, (ii) reimbursement for any
                  expenses as set forth in Section 3.5, through the date of
                  termination, (iii) Employee's Annual Bonus, prorated through
                  the date of termination, and (iv) a severance payment in an
                  amount equal to Two Hundred Eighty Thousand Dollars
                  ($280,000.00), payable in one lump sum, subject to withholding
                  as may be required by law. In addition, if Employee's
                  employment is terminated without cause (other than if Employee
                  is Involuntarily Terminated) or if Employee's employment is
                  terminated due to death or permanent disability, Employee will
                  be credited with an additional twelve (12) months of service
                  toward vesting in the Option shares in addition to the service
                  he has accrued toward vesting through the date of termination.
                  If Employee is Involuntarily Terminated, vesting of the Option
                  shares will be accelerated in full; provided, however,
                  Employee will only vest in 75% of the Option shares if the
                  Corporate Transaction takes place in the first nine months
                  following the date of commencement of Employee's employment.


                  As used in this Section 4.2, Employee shall be deemed
                  "Involuntarily Terminated" if (i) the Company or any successor
                  to the Company terminates

                                       3

                  Employee's employment without cause in connection with or
                  following a Corporate Transaction (as defined in the
                  Company's stock option plan); or (ii) in connection with or
                  following a Corporate Transaction there is (a) a decrease
                  in Employee's title or responsibilities (it being deemed to
                  be a decrease in title and/or responsibilities if Employee
                  is not offered the position of Senior Vice President and
                  Chief Financial Officer of the Company or its successor as
                  well as the acquiring and ultimate parent entity, if any,
                  following the Corporate Transaction), (b) a decrease in pay
                  and/or benefits from those provided by the Company
                  immediately prior to the Corporate Transaction or (c) a
                  requirement that Employee re-locate out of the greater Los
                  Angeles metropolitan area.

5.                ASSIGNMENT. Neither the Company nor Employee may assign this
                  Agreement or any rights or obligations hereunder. This
                  Agreement will be binding upon the Company and its successors
                  and assigns. In the event of a Corporate Transaction, the
                  Company shall cause this Agreement to be assumed by the
                  Company's successor as well as any acquiring or ultimate
                  parent entity, if any, following any Corporate Transaction.

6.       MISCELLANEOUS.

         6.1      This Agreement supersedes any and all other agreements, either
                  oral or in writing, between the parties hereto with respect to

                  Confidentiality and Proprietary Agreement, and constitutes the
                  entire agreement between the Company and the Employee with
                  respect to its subject matter.

         6.2      This Agreement may not be amended, supplemented, modified or

                  hereto and which is authorized by the Company's Board of
                  Directors.

         6.3      This Agreement is made in and shall be governed by the laws of
                  California, without giving effect to its conflicts-of-law
                  principles.

         6.4      In the event that any provision of this Agreement is
                  determined to be illegal, invalid or void for any reason, the
                  remaining provisions hereof shall continue in full force and
                  effect.

                             STOCK PLEDGE AGREEMENT

                  AGREEMENT made as of this 17th day of April, 1999 by and
between NetZero, Inc., a California corporation (the "Corporation") and
Charles S. Hilliard ("Pledgor").

RECITALS

              A. In connection with the purchase of 800,000 shares of the
Corporation's Common Stock (the "Purchased Shares") on the date of this
Agreement from the Corporation, Pledgor has issued that certain promissory
note (the "Note") dated April 17, 1999 payable to the order of the
Corporation in the principal amount of Four Hundred Thousand Dollars
($400,000.00).

              B. Such Note is secured by the Purchased Shares and other
collateral upon the terms set forth in this Agreement.

              NOW, THEREFORE, it is hereby agreed as follows:

              1. GRANT OF SECURITY INTEREST. Pledgor hereby grants the
Corporation a security interest in, and assigns, transfers to and pledges
with the Corporation, the following securities and other property
(collectively, the "Collateral"):

                 (i) the Purchased Shares delivered to and deposited with the
     Corporation as collateral for the Note;

                 (ii) any and all new, additional or different securities or
     other property subsequently distributed with respect to the Purchased
     Shares which are to be delivered to and deposited with the Corporation
     pursuant to the requirements of Paragraph 3 of this Agreement;

                 (iii) any and all other property and money which is
     delivered to or comes into the possession of the Corporation pursuant to
     the terms of this Agreement; and

                 (iv) the proceeds of any sale, exchange or disposition of
     the property and securities described in subparagraphs (i), (ii) or (iii)
     above.

              2. WARRANTIES. Pledgor hereby warrants that Pledgor is the
owner of the Collateral and has the right to pledge the Collateral and that
the Collateral is free from all liens, adverse claims and other security
interests (other than those created hereby).

                                       1
<PAGE>

              3. DUTY TO DELIVER. Any new, additional or different securities
or other property (other than regular cash dividends) which may now or
hereafter become distributable with respect to the Collateral by reason of
(i) any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the Common Stock as a class
without the Corporation's receipt of consideration or (ii) any merger,
consolidation or other reorganization affecting the capital structure of the
Corporation shall, upon receipt by Pledgor, be promptly delivered to and
deposited with the Corporation as part of the Collateral hereunder. Any such
securities shall be accompanied by one or more properly endorsed stock power
assignments.

              4. PAYMENT OF TAXES AND OTHER CHARGES. Pledgor shall pay, prior
to the delinquency date, all taxes, liens, assessments and other charges
against the Collateral, and in the event of Pledgor's failure to do so, the
Corporation may at its election pay any or all of such taxes and other
charges without contesting the validity or legality thereof. The payments so
made shall become part of the indebtedness secured hereunder and until paid
shall bear interest at the minimum per annum rate required to avoid the
imputation of interest income to the Corporation and compensation income to
Pledgor under the federal tax laws.

              5. SHAREHOLDER RIGHTS. So long as there exists no event of
default under Paragraph 10 of this Agreement, Pledgor may exercise all
shareholder voting rights and be entitled to receive any and all regular cash
dividends paid on the Collateral and all proxy statements and other
shareholder materials pertaining to the Collateral.

              6. RIGHTS AND POWERS OF CORPORATION. The Corporation may,
without obligation to do so, exercise at any time and from time to time one
or more of the following rights and powers with respect to any or all of the
Collateral:

                 (i) subject to the applicable limitations of Paragraph 9,
     accept in its discretion other property of Pledgor in exchange for all or
     part of the Collateral and release Collateral to Pledgor to the extent
     necessary to effect such exchange, and in such event the other property
     received in the exchange shall become part of the Collateral hereunder;

                 (ii) perform such acts as are necessary to preserve and
     protect the Collateral and the rights, powers and remedies granted with
     respect to such Collateral by this Agreement; and

                 (iii) transfer record ownership of the Collateral to the
     Corporation or its nominee and receive, endorse and give receipt for, or
     collect by legal proceedings or otherwise, dividends or other distributions
     made or paid with respect to the Collateral, PROVIDED AND ONLY IF there
     exists at the time an outstanding event of default under Paragraph 10 of
     this Agreement. Any cash sums which the Corporation may so receive shall be
     applied to the payment of the Note and any other indebtedness secured
     hereunder, in such order of application as the Corporation deems
     appropriate. Any remaining cash shall be paid over to Pledgor.

              Any action by the Corporation pursuant to the provisions of
this Paragraph 6 may be taken without notice to Pledgor. Expenses reasonably
incurred in connection with such action

                                       2

<PAGE>

shall be payable by Pledgor and form part of the indebtedness secured
hereunder as provided in Paragraph 12.

              7. CARE OF COLLATERAL. The Corporation shall exercise
reasonable care in the custody and preservation of the Collateral. However,
the Corporation shall have no obligation to (i) initiate any action with
respect to, or otherwise inform Pledgor of, any conversion, call, exchange
right, preemptive right, subscription right, purchase offer or other right or
privilege relating to or affecting the Collateral, (ii) preserve the rights
of Pledgor against adverse claims or protect the Collateral against the
possibility of a decline in market value or (iii) take any action with
respect to the Collateral requested by Pledgor unless the request is made in
writing and the Corporation determines that the requested action will not
unreasonably jeopardize the value of the Collateral as security for the Note
and other indebtedness secured hereunder.

              Subject to the limitations of Paragraph 9, the Corporation may
at any time release and deliver all or part of the Collateral to Pledgor, and
the receipt thereof by Pledgor shall constitute a complete and full
acquittance for the Collateral so released and delivered. The Corporation
shall accordingly be discharged from any further liability or responsibility
for the collateral, and the release Collateral shall no longer be subject to
the provision of this Agreement.

              8. TRANSFER OF COLLATERAL. In connection with the transfer or
assignment of the Note (whether by negotiation, discount or otherwise), the
Corporation may transfer all or any part of the Collateral, and the
transferee shall thereupon succeed to all the rights, powers and remedies
granted the Corporation hereunder with respect to the Collateral so
transferred. Upon such transfer, the Corporation shall be fully discharged
from all liability and any further responsibility for the transferred
Collateral.

              9. RELEASE OF COLLATERAL. Provided all indebtedness secured
hereunder (other than payments not yet due and payable under the Note) shall
at the time have been paid in full and there does not otherwise exist any
event of default under Paragraph 10, the Purchased Shares, together with any
additional Collateral which may hereafter be pledged and deposited hereunder,
shall be released from pledge and returned to Pledgor in accordance with the
following provisions:

                 (i) Promptly following (a) payment or prepayment of
     principal of the Note, together with payment of all accrued interest to
     date, one or more of the Purchased Shares held as Collateral hereunder
     shall (subject to the applicable limitations of Paragraphs 9(iii) and
     9(v) below) be released to Pledgor. The number of shares to be so released
     shall be equal to the number obtained by multiplying (i) the total number
     of Purchased Shares held under this Agreement at the time of the payment or
     prepayment, by (ii) a fraction, the numerator of which shall be the amount
     of the principal paid or prepaid and the denominator of which shall be the
     unpaid principal balance of the Note immediately prior to such payment or
     prepayment. In no event, however, shall any fractional shares be released.

                 (ii) Any additional Collateral which may hereafter be
     pledged and deposited with the Corporation (pursuant to the requirements of
     Paragraph 3) with respect to the Purchased Shares shall be released at the
     same time the particular shares of

                                       3

<PAGE>

     Common Stock to which the additional Collateral relates are to be released
     in accordance with the applicable provisions of Paragraph 9(i).

                 (iii) Under no circumstances, however, shall any Purchased
     Shares or any other Collateral be released if previously applied to the
     payment of any indebtedness secured hereunder. In addition, in no event
     shall any Purchased Shares or other Collateral be released pursuant to the
     provisions of Paragraph 9(i) or 9(ii) if, and to the extent, the fair
     market value of the Common Stock and all other Collateral which would
     otherwise remain in pledge hereunder after such release were effected would
     be less than the unpaid principal and accrued interest under the Note.

                 (iv) For all valuation purposes under this Agreement, the
     fair market value per share of Common Stock on any relevant date shall be
     determined in accordance with the following provisions:

                           (A) If the Common Stock is at the time traded
          on The Nasdaq National Market, the fair market value shall be
          the closing selling price per share of Common Stock on the
          date in question, as such prices are reported by the National
          Association of Securities Dealers on its Nasdaq system or any
          successor system. If there is no reported closing selling
          price for the Common Stock on the date in question, then the
          closing selling price on the last preceding date for which
          such quotation exists shall be determinative of fair market
          value.

                           (B) If the Common Stock is at the time listed
          on the New York Stock Exchange or any other securities
          exchange, then the fair market value shall be the closing
          selling price per share of Common Stock on the date in
          question on the securities exchange serving as the primary
          market for the Common Stock, as such price is officially
          quoted in the composite tape of transactions on such exchange.
          If there is no reported sale of Common Stock on such exchange
          on the date in question, then the fair market value shall be
          the closing selling price on the exchange on the last
          preceding date for which such quotation exists.

                      (C) If the Common Stock is at the time
          neither listed on any securities exchange nor traded on The
          Nasdaq National Market, the fair market value shall be
          determined by the Corporation's Board of Directors after
          taking into account such factors as the Board shall deem
          appropriate.

                 (v) In the event the Collateral becomes in whole
     or in part comprised of "margin securities" within the meaning
     of Section 207.2(i) of Regulation G of the Federal Reserve
     Board, then no Collateral shall thereafter be substituted for
     any Collateral under the provisions of Paragraph 6(i) or be
     released under Paragraph 9(i) or (ii), unless there is
     compliance with each of the following additional requirements:

                      (A) The substitution or release must not
          increase the amount by which the indebtedness secured
          hereunder at the time of such substitution or release exceeds
          the maximum loan value (as defined below) of the Collateral
          immediately prior to such substitution or release.

                                                 4
          <PAGE>

                      (B) The substitution or release must not
          cause the amount of indebtedness secured hereunder at the time
          of such substitution or release to exceed the maximum loan
          value of the Collateral remaining after such substitution or
          release is effected.

                      (C) For purposes of this Paragraph 9(v),
          the maximum loan value of each item of Collateral shall be
          determined on the day the substitution or release is to be
          effected and shall, in the case of the shares of Common Stock
          and any additional Collateral (other than margin securities),
          equal the good faith loan value thereof (as defined in Section
          207.2(e)(1) of Regulation G) and shall, in the case of all
          margin securities (other than the Common Stock), equal fifty
          percent (50%) of the current market value of such securities.

         10. EVENTS OF DEFAULT. The occurrence of one or more of the
following events shall constitute an event of default under this Agreement:

                  (i) the failure of Pledgor to pay, when due under the Note,
     any installment of principal or accrued interest after any grace period set
     forth in the Note has expired, if any; or

                  (ii) the wilful failure of Pledgor to perform any material
     obligation imposed upon Pledgor by reason of this Agreement within 30 days
     following written notice to Pledgor detailing such failure; or

                  (iii) the material breach of any warranty of Pledgor
     contained in Paragraph 2 of this Agreement.

              Upon the occurrence of any such event of default, the
Corporation may, at its election, declare the Note and all other indebtedness
secured hereunder to become immediately due and payable and may exercise any
or all of the rights and remedies granted to a secured party under the
provisions of the California Uniform Commercial Code (as now or hereafter in
effect), including (without limitation) the power to dispose of the
Collateral by public or private sale or to accept the Collateral in full
payment of the Note and all other indebtedness secured hereunder.

              Any proceeds realized from the disposition of the Collateral
pursuant to the foregoing power of sale shall be applied first to the payment
of reasonable expenses incurred by the Corporation in connection with the
disposition and then to the payment of the Note and finally to any other
indebtedness secured hereunder. Any surplus proceeds shall be paid over to
Pledgor. However, in the event such proceeds prove insufficient to satisfy
all obligations of Pledgor under the Note which are recourse to Pledgor, then
Pledgor shall remain personally liable for the remaining obligations under
the Note which are recourse to Pledgor.

              11. OTHER REMEDIES. The rights, powers and remedies granted to
the Corporation pursuant to the provisions of this Agreement shall be in
addition to all rights, powers and remedies granted to the Corporation under
any statute or rule of law. Any forbearance, failure or delay by the
Corporation in exercising any right, power or remedy under this Agreement
shall not be deemed to be a waiver of such right, power or remedy. Any single
or partial exercise of any right, power or remedy under this Agreement shall
not preclude the

                                       5

<PAGE>

further exercise thereof, and every right, power and remedy of the Corporation
under this Agreement shall continue in full force and effect unless such right,
power or remedy is specifically waived by an instrument executed by the
Corporation.

              12. COSTS AND EXPENSES. All costs and expenses (including
reasonable attorneys fees) incurred by the Corporation in the exercise or
enforcement of any right, power or remedy granted it under this Agreement
shall become part of the indebtedness secured hereunder and shall constitute
a personal liability of Pledgor payable immediately upon demand and bearing
interest until paid at the minimum per annum rate required to avoid the
imputation of interest income to the Corporation and compensation income to
Pledgor under the federal tax laws.

              13. APPLICABLE LAW. This Agreement shall be governed by and
construed in accordance with the laws of the State of California without
resort to that State's conflict-of-laws rules.

              14. SUCCESSORS. This Agreement shall be binding upon the
Corporation and its successors and assigns and upon Pledgor and the
executors, heirs and legatees of Pledgor's estate.

              15. SEVERABILITY. If any provision of this Agreement is held to
be invalid under applicable law, then such provision shall be ineffective
only to the extent of such invalidity, and neither the remainder of such
provision nor any other provisions of this Agreement shall be affected
thereby.

              IN WITNESS WHEREOF, this Agreement has been executed by Pledgor
and the Corporation on this 17th day of April, 1999.

               4.    EVENTS OF ACCELERATION. The entire unpaid principal

         thirty (30) days or more, the appointment of a receiver or
         trustee to take possession of any property or assets of the Maker or

                     B.    the occurrence of any event of default under

               5.    SPECIAL ACCELERATION EVENT.  In the event the Maker sells

writing and signed by a duly-authorized officer of the Corporation and any such
waiver shall be limited to its express terms.  No delay by the Corporation in
acting with respect to the terms of this Note or the Stock Pledge Agreement
shall constitute a waiver of any breach, default or failure of a condition under
this Note, the Stock Pledge Agreement or the obligations secured thereby.

               The Maker waives presentment, demand, notice of dishonor, notice
of default or delinquency, notice of acceleration, notice of protest and
nonpayment, notice of costs, expenses or losses and interest thereon, notice of
interest on interest and diligence in taking any action to collect any sums
owing under this Note or in proceeding against any of the rights or interests in

                     DISTRIBUTION, LICENSE AND ALLIANCE AGREEMENT

This Distribution, License and Alliance Agreement (the "Agreement") between
Compaq Computer Corporation, with its principal business office at 20555 S.H.
240, Houston, Texas 77070, a Delaware corporation ("Compaq"), and NetZero,
Inc., with its principal business office at 2555 Townsgate Road, Westlake
Village, CA 91361, a California corporation ("NETZERO"), is made effective as
of this 30th day of April, 1999.  Compaq and NetZero are sometimes referred
to individually as a "Party," and collectively as the "Parties."

                                       RECITALS

     WHEREAS, Compaq and NetZero wish to enter into a business alliance to,
among other things, market, promote and offer NetZero branded Internet access
service (the "NetZero ISP Service") which shall be free to the Compaq enduser
at the time the Licensed Product associated with such service is distributed
with the Presario Product Line.

     WHEREAS, Compaq and NetZero each acknowledge that the keys to developing
the desired program are a good faith commitment to solve business and
operational issues through open communication and a willingness to employ
flexible procedures to address any such issues which may arise during the
performance of this Agreement.

     NOW, THEREFORE, AND IN CONSIDERATION of the foregoing premises and for
other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, the Parties agree as follows:

1.0  PURPOSE

     The intent of the  Parties is to work together to allow Compaq to market,
     offer and distribute the Licensed Product on the Presario Product Line
     commencing with the 2C Product Run (the "Products") during the term of this
     Agreement with the goal and purpose of consumer adoption of the NetZero ISP
     Service by purchasers of the Products. Compaq and NetZero agree to work
     together to understand the demands on an ISP service that could be made by
     Compaq customers and identify what may be required by both parties to
     anticipate and handle such demands.

2.0  WORK EFFORT

     This Agreement shall describe:

     a)   the terms and conditions under which Compaq shall have the right and
          obligation to distribute the Licensed Product and Compaq's marketing
          obligations in connection with the distribution of the Licensed
          Products,

     b)   the license terms by which such distribution rights are granted,

     c)   the parties' obligations as they relate to the development, testing
          and integration of the Licensed Product to allow the Licensed Product
          to be

<PAGE>

          bundled or shipped with the Products  shipped during the term of
          this Agreement (the  Products which are shipped with or which
          incorporate the Licensed Product pursuant to this Agreement are
          referred to herein as the "Combined Products"), and

     d)   Compaq's ability to designate an initial start page from Alta Vista
          solely for the Compaq enduser who uses the Licensed Product on the
          Combined Products.

2.1  DISTRIBUTION; EXCLUSIVITY; PROMINENCE

     a)   Commencing with the 2C Run and during the term of this Agreement,
          Compaq shall distribute the Licensed Product with all the Products to
          enable purchasers of the Products to choose and sign-up to NetZero as
          their free ISP.   The parties agree that, as soon as technically
          feasible and subject to NetZero's Licensed Product passing quality
          assurance testing and integration issues as discussed more fully
          below, the Licensed Product shall be incorporated into the Products in
          the same manner as Compaq incorporates the AOL and Compaq branded ISP
          offerings.

     b)   NetZero agrees that it shall not enter into an agreement with any
          other personal computer manufacturer to permit such manufacturer to
          distribute or combine in any manner the Licensed Product in
          conjunction with the personal computers of such manufacturer where
          such distribution takes place during the period commencing June 1,
          1999 and ending February 28, 2000 (the "Exclusivity Period").  In
          addition, NetZero agrees not to enter into an agreement with any of
          Compaq's authorized dealers for the Products to permit such retailers
          to distribute copies of the Licensed Product where such distribution
          takes place in North America during the Exclusivity Period.

     c)   Compaq agrees that it shall not distribute during the Exclusivity
          Period, or enter into any agreement permitting a third party to
          distribute during the Exclusivity Period, Products bundled or combined
          in any manner with any Free ISP Service (including any service offered
          by Compaq) other than the Licensed Product, excluding (i) Compaq may
          offer America Online as a Free ISP Service if required to by AOL and
          (ii) Compaq may sell Products to  or in support of Affinity Partners.
          The phrase "Free ISP Service" for the purpose of this Agreement shall
          mean any internet access service, including a service offered or
          provided by Compaq, which requires the purchaser of such service to
          pay less than five dollars ($5.00) per month, excluding any free
          limited trial period of three (3) months or less.  The intention of
          the foregoing is to make NetZero the exclusive Free ISP on the
          Products.

     d)   If America Online commences offering a Free ISP Service on or in
          connection with the Products, then neither party shall be bound by the
          restrictions set forth in Sections 2.1(b) and 2.1(c) above.   In
          addition, NetZero will have the option to terminate the restrictions
          on both Parties set forth in Sections 2.1(b) and 2.1(c) above if the
          conversion rate for the Licensed Product on the Combined Products is
          less than twenty percent (20%) during the Measurement Period
          determined as follows.  The

                                       2
<PAGE>

          conversion rate shall mean the percentage of purchasers of Combined
          Products who subscribe to the NetZero ISP Service as determined
          during a particular period.  Compaq shall prepare weekly summaries
          of Combined Product sales to end-users which shall contain such
          information as shall be mutually acceptable to the Parties but
          which must, at a minimum, provide NetZero with enough information
          to determine how many Combined Products were sold to end-users in a
          particular week and what percentage of the purchasers of such
          Combined Products subscribed to the NetZero ISP Service.  The
          Parties shall review the conversion rate on a weekly basis and, if
          the conversion rate for the Combined Products in the 3C run during
          August 1999 is less than 20%, the Parties shall meet to mutually
          determine what additional methods should be implemented to increase
          the conversion rate and shall use commercially reasonable efforts
          to implement such methods during the month of September.  If the
          conversion rate during the first two weeks of the month of October,
          1999 (the "Measurement Period") is not at least 20%, then NetZero
          shall thereafter have the option to terminate the restrictions on
          both Parties (but not just on one Party) in Sections 2.1(b) and
          2.1(c) above effective upon the delivery of written notice to
          Compaq.

     e)   To the extent the Licensed Product is required to be distributed with
          Products pursuant to this Agreement, the NetZero ISP Service offering
          shall be prominently displayed on screen as well as in marketing
          materials in a manner which shall be mutually agreed to between the
          Parties but which shall, subject to (i) Compaq's contractual
          restrictions set forth below with respect to AOL and (ii) Compaq's
          right to be displayed more prominently  than AOL, result in the
          NetZero ISP Service being the most prominently displayed ISP service.
          NetZero acknowledges that America Online is a business partner with
          Compaq in providing Internet access and that Compaq is subject to
          certain pre-existing contractual relationships with America Online
          which may result in AOL being displayed more prominently in accordance
          with such preexisting contractual obligations.  However, at a minimum,
          NetZero shall have at least  equal space with the most prominently
          displayed ISP offering (and in no event less than 1/3 of the page)  on
          the first  page that displays  either the Compaq or the  AOL Internet
          access offers on the Products, an example of which is  graphically
          shown on Schedule 2.1(e)(1) attached hereto.  The content in such
          space shall be provided by NetZero, and shall be subject to Compaq's
          approval and such approval shall not be unreasonably withheld.  With
          respect to the button (or any replacement button) on such page that
          prompts the user to "Next" in the experience, such button may either
          take the user to the NetZero sign up, will complete the registration
          process (which shall not include any  ISP sign-up offers), or to
          another page that will have NetZero and Compaq as the only brands from
          which to choose.  Such page will provide equal prominence to the Net
          Zero and Compaq offerings.  The  desktop shall also include an icon
          for the NetZero ISP service which will launch to the Licensed Product.
          Until web-based registration is available

                                       3
<PAGE>

          from NetZero enabling the end-user to launch NetZero from the page
          referenced above, acceptance of the NetZero service on such page
          shall guide the end-user to the site or icon through mutually
          acceptable instructions.

2.2  DEVELOPMENT, TESTING AND TECHNICAL REQUIREMENTS

     a)   Compaq and NetZero agree to work together in the development, testing,
          and integration of the current and future versions of the Licensed
          Product, as may be made available  during the Term of this Agreement.
          The  intent of the development effort will be to make the Licensed
          Product available in a manner to optimize distribution with the retail
          marketing cycles of the Product.

     b)   The work effort shall consist of two phases. The first phase shall be
          to test, validate, and reproduce the NetZero 1.6.x version of the
          Licensed Product so it can be distributed with the Products in the
          form of a CD in the box.  The second phase will be the integration of
          the Licensed Product into the Compaq Out of Box Experience ("OoBE")
          for the 3C Run and the other distributions during the Term of this
          Agreement. This integration is intended to be implemented by
          incorporating the Licensed Product into the Products in the same
          manner other ISP Services are incorporated into the Products
          (including web-based registration when available), subject to the
          Licensed Product meeting reasonable technical specifications in
          accordance with reasonable timelines related to the 3C Run required to
          meet the retail marketing cycles.

     PHASE 1

     Compaq and NetZero shall work together to test and qualify the NetZero
     version 1.6.x of the Licensed Product. In order for
     Compaq to be obligated to include the Licensed Product in the Products, the
     Licensed Product when included with a Product must meet the following basic
     quality standards:  (i) it must allow a customer who has purchased a
     Product to load the Licensed Product from a CD, (ii) the CD shall install
     the program either through an auto load or by providing writing
     instructions on how to install the program,  (i.e. insert disk, click on
     the Windows Start key, click on Run, etc),  and (iii) shall not cause any
     of the Compaq standard features or functions of the  Product  to fail or
     cease to function.

     The parties shall work together to ensure that the Licensed Product or any
     of its Updates, Enhancements, Modifications or Versions shall not cause any
     of the features or functions of the Product to fail or cease to function.
     To the extent that NetZero is not having to respond to a security or other
     critical customer care issue relating to the NetZero ISP Service, NetZero
     shall be required to provide Compaq with advance notice of any changes to
     the Licensed Product by email to specified individuals within Compaq and
     Compaq shall have the opportunity to test all such Updates, Enhancements,
     Modifications and Versions to ensure they function properly with the
     Products.  The Parties understand that NetZero will effect changes to the
     Licensed Product on a regular basis and that it is important

                                       4
<PAGE>

     for Compaq to test promptly.  Compaq agrees to perform testing within 48
     hours of delivery of the changes.  If at any point in the testing of a
     Licensed Product or any Update, Modification, Enhancement or Version,
     Compaq determines that there is a material problem attributable to the
     Licensed Product that would prevent the Licensed Product from achieving
     basic quality standards, Compaq shall not have an obligation to ship the
     Licensed Product, until such time as the material problems are cured.
     NetZero shall be immediately notified in writing and the Parties shall
     use their commercially reasonable efforts to resolve the issue as
     expeditiously as possible.  NetZero acknowledges that if there is a
     functionality problem in the Licensed Product (other than a problem
     attributable to the Product, any change to the Products or any other
     third party software included in the Product) which causes it to fail to
     achieve basic quality standards, and if the parties use commercially
     reasonable efforts to resolve the same after written notice and a thirty

          the right to determine at Compaq's sole discretion that the Default

          notice of its intent that the Default Start Page shall no longer be
          an AltaVista start page.  In the event that Compaq chooses not to
          use an AltaVista start page as the Default Start Page NetZero shall
          be entitled to replace the Default Start Page with such other start
          page as it selects, it being understood that NetZero may be

          Compaq URL.

     The Advantage Window is a persistent window, which is controlled and
     maintained by NetZero and which, among other features, is used to display
     advertisements.  Compaq acknowledges that NetZero shall determine the
     function, look, and feel of such window.   NetZero and Compaq agree to
     coordinate to minimize material inconsistencies between the icons and the
     functionality of the buttons on the keyboard and in the Advantage Window,

     mutually agree to a service and support schedule, which will be attached
     hereto as Schedule 2.4.  The failure of the parties to prepare and attach a
     Schedule shall not be deemed to be a breach of this Agreement.  In the
     event a Schedule is not attached NetZero agrees that the level of service
     and support provided to a purchaser of Combined Products using NetZero's
     ISP Service shall be at least the same level as provided to other users of
     the NetZero ISP Service.

     relating to the utilization of URL targeted marketing or the protection
     therefrom, and the technical limitations associated with the provisioning
     of URL targeted marketing.

     If Compaq desires to sell its allocation through demographic or other
     targeting to specific groups, NetZero agrees to assist Compaq and to
     provide Compaq with up to 10% of the Ad inventory associated with a
     particular group that Compaq wishes to target.  NetZero agrees to use
     commercially reasonable efforts to accommodate Compaq's request to help
     place any unsold or unused portions of Compaq's allocation.   Compaq and

     being able to maximize the ability to use the targeting advertising ability
     within the Advantage Window to obtain a high ad rate.

               licenses granted to Compaq and that it is free of any
               obligation that would prevent it from entering into this
               Agreement or performing its obligations hereunder.

          3.   To NetZero's knowledge, the Licensed Products and/or their use
               and distribution alone and/or in combination with Products
               will not infringe any patent, copyright, trade secret,
               trademark or any other legal or equitable rights of any third
               party.

     9.2  Compaq warrants that:

          1.   It has the right to grant the rights granted to NetZero in
               this Agreement.

          2.   Except as specifically set forth herein, It has not made and
               will not make any commitments to any third party inconsistent
               with or in derogation of the rights and licenses granted to
               NetZero and that it is free of any obligation that would
               prevent it from entering into this Agreement or performing its
               obligations hereunder.

          3.   To Compaq's knowledge, the Products and/or their use and
               distribution alone and/or in combination with the Products
               will not infringe any patent, copyright, trade secret,

     9.3  THE WARRANTIES STATED HEREIN ARE EXPRESSLY IN LIEU OF ALL OTHER
          WARRANTIES, AND UNLESS OTHERWISE EXPRESSLY STATED HEREIN, NEITHER
          PARTY MAKES ANY OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING, BUT
          NOT LIMITED TO, ANY EXPRESS OR IMPLIED WARRANTY OF MERCHANTABILITY OR
          FITNESS FOR A PARTICULAR PURPOSE.

     9.4  Each party shall indemnify, defend and hold the other  (and its
          officers and  employees) harmless against all suits, actions, costs,
          expenses, damages, settlements, judgments, and all other liabilities
          resulting from claims by third parties that, with respect to Compaq,
          the Products and with respect to NetZero the Licensed Products (or
          their marketing, distribution, combination or use as allowed by this
          Agreement) infringe any United States patent, copyright, trade secret,
          trademark, or any other proprietary rights., The foregoing indemnity
          shall not apply to the extent the claim is based on the manner in
          which the parties have incorporated their products together. NetZero
          shall indemnify, defend and hold Compaq (and its officers and
          employees) harmless against all suits, actions, costs, expenses,
          damages, settlements, judgments, and all other liabilities resulting
          from claims by third parties that the collection or use of information
          about NetZero's subscribers by NetZero violates any privacy or other
          right of such subscriber.  Compaq shall indemnify, defend and hold
          NetZero (and its officers and  employees) harmless against all suits,
          actions, costs, expenses, damages, settlements, judgments, and all
          other liabilities resulting from claims by third parties that the use
          of information about NetZero's subscribers by Compaq violates any
          privacy or other right of such subscriber.  Each party shall promptly
          notify the other in writing when it becomes aware of any claim upon
          which a request for indemnity may be made hereunder, provided that the
          failure to give such notice shall only constitute a waiver of an
          indemnified party's rights hereunder to the extent the indemnifying
          party is materially prejudiced by the failure to promptly provide such
          notice.  The indemnifying party shall assume and thereafter have
          control of any suit involving such claim and any settlement
          negotiations.  The indemnifying party shall promptly pay any such
          settlement or final judgment entered against the indemnified party.
          If a court determines that a Licensed Product or a Product, as the
          case may be, or any part thereof, infringes any United States patent,
          copyright, trade secret, trademark or other right covered by this
          indemnity, and the sale or use of the Licensed Product or the Product,
          as the case may be, or any part thereof, is, as a result, enjoined,
          then the indemnifying party may, at its option and expense (but in
          addition to its obligations above): (i) procure for the other the
          right under such patent, copyright, trade secret, trademark or other
          right to sell or use as appropriate, the Licensed Product or Product
          or such parts thereof; (ii) replace the Licensed Product or Product,
          or parts thereof, with other suitable, functionally equivalent and
          non-infringing product or parts; or (iii) suitably modify the Licensed
          Product or Product or parts thereof.

     9.5  EXCEPT FOR THE UNAUTHORIZED USE OF A PARTY'S PROPRIETARY RIGHTS
          HEREUNDER, NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY
          INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, OR CONSEQUENTIAL DAMAGES,
          INCLUDING LOST PROFITS, ARISING OUT OR RESULTING FROM THIS AGREEMENT
          EVEN IF THE OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
          DAMAGES.  THE FOREGOING SHALL APPLY REGARDLESS OF THE NEGLIGENCE OR
          OTHER FAULT OF EITHER PARTY AND REGARDLESS OF WHETHER SUCH LIABILITY
          SOUNDS IN CONTRACT, NEGLIGENCE, TORT, OR ANY OTHER THEORY OF LEGAL
          LIABILITY.

10.0 TERM AND TERMINATION OF AGREEMENT

     10.1 Unless earlier terminated as provided below, the term of this
          Agreement shall be for one (1) year from the date of execution of this
          Agreement.   At either Party's request, the Parties shall commence
          meeting prior to the end of the term to determine whether to extend
          the term of this Agreement.

     10.2 If either party hereto materially breaches any of the terms and
          conditions of this Agreement, the other party may give written notice
          to the defaulting party specifying the actions or omissions which
          constitute a breach of this Agreement, and in the event that any
          breach so indicated shall not be remedied by the defaulting party
          within thirty (30) days after such notice, the party not in default
          may by further written notice to the defaulting party terminate this
          Agreement, and, except as expressly provided otherwise in this
          Agreement, this Agreement and all the rights herein granted shall
          terminate five (5) days after date of mailing of such notice of
          termination.  Failure of either party to so terminate this Agreement
          due to a breach on the part of the other party shall not prejudice its
          rights to terminate for a subsequent breach by the other.

     10.3 All sublicenses granted to Customers under this Agreement, and all
          obligations with respect thereto set forth in Sections, 4 and 9 shall
          survive the expiration or termination of this Agreement. Thereafter,
          Compaq agrees to return or destroy all additional copies of the
          Licensed Software in its possession and to make no further use of
          NetZero's trademarks or trade names.

     10.4 Upon termination or otherwise, neither party shall have an obligation
          to reimburse the other for any expenses or costs incurred by such
          party in performing hereunder.    Any costs or expenses incurred by
          either party in connection with performing under this Agreement shall,
          unless otherwise expressly provided herein, be at that party's sole
          risk and based upon its own independent business judgment.

                   SERIES D PREFERRED STOCK PURCHASE AGREEMENT

                  THIS SERIES D PREFERRED STOCK PURCHASE AGREEMENT is made as of
the 10th day of May, 1999, among NetZero, Inc., a California corporation (the
"Company"), and the investors listed on Schedule A hereto (the "Investors").

                  THE PARTIES HEREBY AGREE AS FOLLOWS:

below) the Amended and Restated Articles of Incorporation in the form
attached hereto as Exhibit A (the "Restated Articles").

         1.2 SALE AND ISSUANCE OF SERIES D PREFERRED STOCK. Subject to the
terms and conditions of this Agreement, each Investor agrees to purchase at
the Closing, and the Company agrees to sell and issue to each such Investor
at the Closing, that number of shares of the Company's Series D Preferred
Stock (as defined below) set forth opposite each such Investor's name on
Schedule A for a purchase price of $2.76 per share.

         1.3 CLOSING. The purchase and sale of the Series D Preferred Stock
(the "Closing") shall take place at the offices of Brobeck, Phleger &

mutually agree upon orally or in writing (the "Closing Date"). At the
Closing, the Company shall deliver to each Investor a certificate
representing the Series D Preferred Stock that such Investor is purchasing
against payment of the purchase price therefor by check or wire transfer;
provided, the Company may, at its sole discretion, accept subscriptions from
additional investors (who shall also be deemed Investors hereunder) and the

     2.  REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company hereby
represents and warrants to each Investor that, except as set forth on a

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

         2.2 CAPITALIZATION  AND VOTING  RIGHTS.  The  authorized  capital

opinions of counsel for transactions made pursuant to Rule 144 except in
unusual circumstances.

              (c) (i) Notwithstanding the provisions of paragraphs (a) and

partner of such partnership or a retired partner of such partnership who
retires after the date hereof, or to the estate of any such partner or
retired partner, a transfer by gift, will or intestate succession of any
partner to his or her spouse or to the siblings, lineal descendants or
ancestors of such partner or his or her spouse or (ii) a transfer to an
Affiliate (as such term is defined in Rule 12(b)(2) promulgated under the
Securities Exchange Act of 1934, as amended), if the transferee agrees in

         6.1 CLOSING. The obligation of the Company to sell and issue the
Series D Preferred Stock which the Company has agreed to issue on the Closing

Company:

              (a) REPRESENTATIONS AND WARRANTIES. The representations and
warranties of the Investors contained in Section 3 shall be true on and as of
the Closing with the same effect as though such representations and

              (b) PAYMENT OF PURCHASE PRICE. The Investors shall have

              (c) QUALIFICATIONS. All authorizations, approvals, or permits,

      7. MISCELLANEOUS.

         7.1 SURVIVAL OF WARRANTIES. The warranties, representations and
covenants of the Company and Investors contained in or made pursuant to this
Agreement shall survive the execution and delivery of this Agreement and the
Closing for a period of one (1) year from the Closing Date and shall in no
way be affected by any investigation of the subject matter thereof made by or
on behalf of the Investors or the Company.

         7.2 SUCCESSORS AND ASSIGNS. Except as otherwise provided herein, the
terms and conditions of this Agreement shall inure to the benefit of and be
binding upon the respective successors and assigns of the parties (including
transferees of any Securities). Nothing in this Agreement, express or
implied, is intended to confer upon any party other than the parties hereto
or their respective successors and assigns any rights, remedies, obligations,
or liabilities under or by reason of this Agreement, except as expressly
provided in this Agreement.

         7.3 GOVERNING LAW. This Agreement shall be governed by and construed
under the laws of the State of California as applied to agreements among
California residents entered into and to be performed entirely within
California.


                                      12

<PAGE>

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

         7.5 TITLES AND SUBTITLES. The titles and subtitles used in this
Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

         7.6 NOTICES. Unless otherwise provided, any notice required or
permitted under this Agreement shall be given in writing and shall be deemed
effectively given upon personal delivery to the party to be notified or upon
deposit with the United States Postal Service, by registered or certified
mail, postage prepaid and addressed to the party to be notified at the
address indicated for such party on the signature page hereof, or at such
other address as such party may designate by ten (10) days' advance written
notice to the other parties.

         7.7 FINDER'S FEE. Each party represents that it neither is nor will
be obligated for any finders' fee or commission in connection with this
transaction. Each Investor agrees to indemnify and to hold harmless the
Company from any liability for any commission or compensation in the nature
of a finders' fee (and the costs and expenses of defending against such
liability or asserted liability) for which such Investor or any of its
officers, partners, employees, or representatives is responsible and the
Company agrees to indemnify and hold harmless each Investor from any
liability for any commission or compensation in the nature of a finders' fee
(and the costs and expenses of defending against such liability or asserted
liability) for which the Company or any of its officers, employees or
representatives is responsible.

         7.8 EXPENSES. Irrespective of whether the Closing is effected, the
Company shall pay all costs and expenses that it incurs with respect to the
negotiation, execution, delivery and performance of this Agreement. If any
action at law or in equity is necessary to enforce or interpret the terms of
this Agreement, the prevailing party shall be entitled to reasonable
attorney's fees, costs and necessary disbursements in addition to any other
relief to which such party may be entitled.

         7.9 AMENDMENTS AND WAIVERS. Any term of this Agreement may be
amended and the observance of any term of this Agreement may be waived
(either generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and the holders
of a majority of the Common Stock issued upon conversion of the Series D
Preferred Stock (assuming the conversion of the Series D Preferred Stock).
Any amendment or waiver effected in accordance with this paragraph shall be
binding upon each holder of any securities purchased under this Agreement at
the time outstanding (including securities into which such securities are
convertible), each future holder of all such securities, and the Company.

         7.10 DISPUTES. If the parties are unable, after good faith
negotiations, which each hereby covenants to undertake, to resolve any
dispute arising between them within fifteen (15) days after notice is given
of such dispute, then the dispute will be referred to arbitration (which the
parties agree is the exclusive means of resolving any such dispute) before
one (1) arbitrator in Los Angeles County, California, or any other place
mutually agreed upon by the


                                      13

<PAGE>

parties hereto, in accordance with the applicable rules then in effect of the
Judicial Arbitration and Mediation Service (the "JAMS Rules") (or any other
form of arbitration mutually acceptable to the parties). The determination
made in accordance with the JAMS Rules shall be delivered in writing to the
parties hereto and shall be final, binding and conclusive on the parties
hereto, and the amount of the claim, if any, determined to exist shall be a
valid claim and no further remedy shall be available to either party with
respect to such dispute and judgment may be entered upon such decision in
accordance with applicable law in any court having jurisdiction thereof. The
arbitration award shall include (i) a provision that the prevailing party in
such arbitration recover its costs relating to the arbitration and reasonable
attorneys' fees from the other party, (ii) the amount of such costs and fees,
and (iii) an order that the losing party pay the fees and expenses of the
arbitrator.

         7.11 SEVERABILITY. If one or more provisions of this Agreement are
held to be unenforceable under applicable law, such provision shall be
excluded from this Agreement and the balance of the Agreement shall be
interpreted as if such provision were so excluded and shall be enforceable in
accordance with its terms.

         7.12 AGGREGATION OF STOCK. All shares of Series D Preferred Stock
held or acquired by affiliated entities or persons shall be aggregated
together for the purpose of determining the availability of any rights under
this Agreement.

         7.13 ENTIRE AGREEMENT. This Agreement and the documents referred to
herein constitute the entire agreement among the parties and no party shall
be liable or bound to any other party in any manner by any warranties,
representations, or covenants except as specifically set forth herein or
therein.

                AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT

         THIS AMENDED AND RESTATED INVESTORS' RIGHTS AGREEMENT ("Agreement")
is made as of the 10th day of May 1999 by and between NetZero, Inc., a
California corporation (the "Company"), the investors listed on Schedule A
hereto, each of which is herein referred to as an "Investor," the officer
listed on Schedule B hereto, who shall be referred to as an "Officer" herein,
and the founders listed on Schedule C hereto, each of which is referred to
herein as a "Founder." This Agreement shall become effective upon the closing
of the Purchase Agreement as defined below.

                                    RECITALS

         WHEREAS, the Company and certain of the Investors are parties to the
Series D Preferred Stock Purchase Agreement of even date herewith (the
"Purchase Agreement");

         WHEREAS, the Company previously entered into an Amended and Restated
Investors' Rights Agreement dated as of January 27, 1999 (the "Prior
Agreement") among the Company, certain Investors and the Founders; and

         WHEREAS, in order to induce the Company to enter into the Purchase
Agreement and to induce certain of the Investors to invest funds in the
Company pursuant to the Purchase Agreement, the Investors, Founders and the
Company hereby agree that this Agreement shall govern the rights of the
Investors and the Founders to cause the Company to register shares of Common
Stock issued or issuable to the Investors and the Founders and certain other
matters as set forth herein and, upon the effectiveness of this Agreement,
the Prior Agreement shall be terminated and of no further force or effect.

         NOW, THEREFORE, THE PARTIES HEREBY AGREE AS FOLLOWS:

         1.    REGISTRATION RIGHTS.  The Company covenants and agrees as
follows:

         1.1   DEFINITIONS.  For purposes of this Section 1:

         (a)   The term "Act" means the Securities Act of 1933, as amended.

         (b)   The term "Affiliate" means with respect to any corporation,
entity or individual, a wholly-owned subsidiary or parent of, or any
corporation or entity that is, within the meaning of the Act, controlling,
controlled by or under common control with, such corporation, entity or
individual.

         (c)   The term "Form S-3" means such form under the Act as in effect
on the date hereof or any registration form under the Act subsequently
adopted by the SEC which permits inclusion or incorporation of substantial
information by reference to other documents filed by the Company with the SEC.


<PAGE>


         (d)   The term "Holder" means any person owning or having the right
to acquire Registrable Securities or any assignee thereof in accordance with
Section 1.13 hereof.

         (e)   The term "1934 Act" shall mean the Securities Exchange Act of
1934, as amended.

         (f)   The term "register," "registered" and "registration" refer to a
registration effected by preparing and filing a registration statement or
similar document in compliance with the Act, and the declaration or ordering
of effectiveness of such registration statement or document.

         (g)   The term "Registrable Securities" means (i) the Common Stock
issuable or issued upon conversion of the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock and Series D Preferred Stock, (ii)
the shares of Common Stock issued or issuable to the Founders or the Officer;
provided, however, that as to the Founders, such shares of Common Stock shall
not be deemed Registrable Securities and the Founders shall not be deemed
Holders for the purposes of Section 1.2 or 1.12, and (iii) any Common Stock
of the Company issued as (or issuable upon the conversion or exercise of any
warrant, right or other security which is issued as) a dividend or other
distribution with respect to, or in exchange for or in replacement of, the
Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock
and Series D Preferred Stock and the shares referenced in (i) and (ii) above,
excluding in all cases, however, any Registrable Securities sold by a Holder
in a transaction in which such Holder's rights under this Section 1 are not
assigned.

         (h)   The number of shares of "Registrable Securities then
outstanding" shall be determined by the number of shares of Common Stock
outstanding which are, and the number of shares of Common Stock issuable
pursuant to then exercisable or convertible securities which are, Registrable
Securities.

         (i)   The term "Relative" shall mean, with respect to an individual,
such individual's spouse, and the ancestors, lineal descendants and siblings
of such individual or such individual's spouse who acquire Registrable
Securities by gift, will or intestate succession.

         (j)   The term "SEC" shall mean the Securities and Exchange
Commission.

         1.2   REQUEST FOR REGISTRATION.

         (a)   If the Company shall receive at any time after the earlier of
(i) August 15, 2000, or (ii) one (1) year after the effective date of the
first registration statement for a public offering of securities of the
Company (other than a registration statement relating either to the sale of
securities to employees of the Company pursuant to a stock option, stock
purchase or similar plan or a SEC Rule 145 transaction), a written request
from the Holders (other than the Officer) of at least twenty percent (20%) of
the Registrable Securities then outstanding (including the Holders of
Registrable Securities attributable to Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock representing at least ten
percent (10%) of the Registrable Securities then outstanding) that the
Company file a registration statement under the Act covering the registration
of at least twenty percent (20%) of such Holders' Registrable

                                       2
<PAGE>

Securities (or any lesser percentage if the anticipated gross receipts from
the offering would exceed $5,000,000), then the Company shall:

               (i)    within ten (10) days of the receipt thereof, give
written notice of such request to all Holders in accordance with Section 3.5
hereof; and

               (ii)   use its best efforts to effect as soon as practicable,
the registration under the Act of all Registrable Securities which the
Holders request to be registered, subject to the limitations of subsections
1.2(b), (c) and (d), within twenty (20) days of the mailing of such notice by
the Company in accordance with Section 3.5.

         (b)   The Holders initiating the registration request hereunder
("Initiating Holders") shall, subject to subsection 1.2(f), distribute the
Registrable Securities covered by their request by means of an underwriting,
and the Company shall include such information in the written notice referred
to in subsection 1.2(a)(i). The underwriter or underwriters will be selected
by the Company and shall be reasonably acceptable to a majority in interest
of the Initiating Holders. The right of any Holder to include such Holder's
Registrable Securities in such underwritten registration shall be conditioned
upon such Holder's participation in such underwriting and the inclusion of
such Holder's Registrable Securities in the underwriting (unless otherwise
mutually agreed by a majority in interest of the Initiating Holders and such
Holder) to the extent provided herein. All Holders proposing to distribute
their securities through such underwriting shall (together with the Company
as provided in subsection 1.4(e)) enter into an underwriting agreement in
customary form with the underwriter or underwriters selected for such
underwriting. 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 underwriting shall be
eliminated or allocated among all Holders thereof, including the Initiating
Holders, in proportion (as nearly as practicable) to the amount of
Registrable Securities owned by each Holder at the time of the filing of the
registration statement.

         (c)   Notwithstanding subsection 1.2(b), if the Company shall
furnish to Holders requesting a registration statement pursuant to this
Section 1.2, a certificate signed by the Chief Executive Officer or President
of the Company stating that in the good faith judgment of the Board of
Directors of the Company, it would be seriously detrimental to the Company
and its shareholders for such registration statement to be filed and it is
therefore essential to defer the filing of such registration statement, the
Company shall have the right to defer taking action with respect to such
filing for a period of not more than one hundred twenty (120) days after
receipt of the request of the Initiating Holders; provided, however, that the
Company may not utilize this right more than once in any twelve (12)-month
period.

         (d)   Notwithstanding anything else set forth in this Section 1.2, the
Company shall not be obligated to effect, or to take any action to effect, any
registration pursuant to this Section 1.2:


                                       3
<PAGE>


               (i)    After the Company has effected two registrations
pursuant to this Section 1.2 and (a) such registrations have been declared or
ordered effective and did not include shares of Common Stock sold by the
Company and (b) the Initiating Holders were able to register and sell at
least fifty percent (50%) of the Registrable Securities requested by such
Holders to be included in such registration; or

               (ii)   During the period starting with the date sixty (60)
days prior to the Company's good faith estimate of the date of filing of, and
ending on a date one hundred eighty (180) days after the effective date of, a
registration subject to Section 1.3 hereof; provided that the Company is
actively employing in good faith all reasonable efforts to cause such
registration statement to become effective; or

               (iii)  Within twelve (12) months of the effective date of
another registration effected pursuant to this Section 1.2; or

               (iv)   If the Initiating Holders propose to dispose of shares
of Registrable Securities that may be immediately registered on Form S-3
pursuant to a request made pursuant to Section 1.12 below.

         (e)   The Company may include in any underwritten registration under
this Section 1.2 any other shares of Common Stock (including, without
limitation, issued and outstanding shares of Common Stock as to which the
holders thereof have contracted with the Company for "piggyback" registration
rights and all shares of Common Stock held by the Founders, so long as the
inclusion in such registration of such shares (i) will not, in the opinion of
the managing underwriter of such registration, interfere with the successful
marketing in accordance with the intended method of sale or other disposition
of all the shares of Registrable Securities sought to be registered by the
Holder or Holders of Registrable Securities pursuant to this Section 1.2 and
(ii) will not result in the exclusion from such registration of any
Registrable Securities. If it is determined as provided above that there will
be such interference, the other shares of Common Stock sought to be included
by the Company shall be excluded to the extent deemed appropriate by the
managing underwriter of such registration.

         (f)  Notwithstanding anything else set forth in this Agreement, the
Company shall not be required to effect a registration under this Section 1.2
unless such registration is a firm commitment underwritten offering with a
nationally recognized underwriter.

         1.3  COMPANY REGISTRATION. 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
stock or other securities under the Act in connection with the public
offering of such securities solely for cash (other than (i) a registration
relating solely to the sale of securities to participants in a Company stock
or stock option plan, (ii) a registration on any form which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of the Registrable Securities
(including, without limitation, a registration in connection with a bona fide
business acquisition of or by the Company), or (iii) a registration in which
the only Common Stock being registered is Common Stock issuable upon
conversion of debt securities which are also being registered), the Company
shall, at such time, promptly give each Holder written notice in


                                       4
<PAGE>


accordance with Section 3.5 of such registration. Upon the written request of
each Holder given within twenty (20) days after mailing of such notice by the
Company, the Company shall, subject to the provisions of Section 1.8, cause
to be registered under the Act all of the Registrable Securities that each
such Holder has requested to be registered.

         1.4   OBLIGATIONS OF THE COMPANY. Whenever required under this
Agreement to use its best efforts 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 (but not including the
Registrable Securities held by any Founders) registered thereunder, keep such
registration statement effective for a period of up to ninety (90) days or
until the distribution contemplated in the Registration Statement has been
completed; provided, however, that (i) such 90-day period shall be extended
for a period of time equal to the period the Holder refrains from selling any
securities included in such registration at the request of the managing
underwriter of Common Stock (or other securities) of the Company; and (ii) in
the case of any registration of Registrable Securities on Form S-3 which are
intended to be offered on a continuous or delayed basis, such ninety (90)-day
period shall be extended, if necessary, to keep the registration statement
effective until all such Registrable Securities are sold, provided that Rule
415, or any successor Rule under the Act, permits an offering on a continuous
or delayed basis, and provided further that applicable rules under the Act
governing the obligation to file a post-effective amendment permit, in lieu
of filing a post-effective amendment which (i) includes any prospectus
required by Section 10(a)(3) of the Act or (ii) reflects facts or events
representing a material or fundamental change in the information set forth in
the registration statement, the incorporation by reference of information
required to be included in (i) and (ii) above to be contained in periodic
reports filed pursuant to Section 13 or 15(d) of the 1934 Act in the
registration statement.

         (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 Act with respect to the disposition of all securities covered by such
registration statement.

         (c)  Furnish to the Holders participating in such registration such
numbers of copies of a prospectus, including a preliminary prospectus, in
conformity with the requirements of the 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 such other securities or Blue
Sky laws of such jurisdictions as shall be reasonably requested by the
Holders; 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 states or jurisdictions,
unless the Company is already subject to service in such jurisdiction and
except as may be required by the Act.


                                       5
<PAGE>


         (e)  In the event of any underwritten public offering, enter into
and perform its obligations under an underwriting agreement, in usual and
customary form, with the managing underwriter of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

         (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 Act of the happening of any event as a
result of which the registration statement, prospectus or any document
incorporated or deemed to be incorporated therein by reference 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 and, at the
written request of the holders of a majority of the Registrable Securities
registered under such Registration Statement, promptly prepare and furnish to
such Holder a reasonable number of copies of a post-effective amendment to
the registration statement or a supplement to the prospectus or any document
incorporated or deemed incorporated therein by reference so that, as
thereafter delivered to the purchasers of the Registrable Securities being
sold thereunder, such prospectus will not contain an untrue statement of
material fact or omit to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances
under which they were made, not misleading; provided, however, the provisions
of any underwriting agreement which also deal with the subject matter of this
paragraph shall supersede in all respects the provisions of this paragraph.

         (g)   Cause all such Registrable Securities registered pursuant
hereto to be listed on each securities exchange on which similar securities
issued by the Company are then listed.

         (h)   Provide a transfer agent and registrar for all Registrable
Securities registered hereunder and a CUSIP number for all such Registrable
Securities, in each case not later than the effective date of such
registration.

         1.5   FURNISH INFORMATION.

         (a)   It shall be a condition precedent to the obligations of the
Company to take any action pursuant to this Section 1 with respect to the
Registrable Securities of any selling Holder that such Holder shall furnish
to the Company such information regarding itself, the Registrable Securities
held by it, and the intended method of disposition of such securities as
shall be required to effect the registration of such Holder's Registrable
Securities.

         (b)   The Company shall have no obligation with respect to any
registration requested pursuant to Section 1.2 or Section 1.12 if the number
of shares or the anticipated aggregate offering price of the Registrable
Securities to be included in the registration does not equal or exceed the
number of shares or the anticipated aggregate offering price required to
originally trigger the Company's obligation to initiate such registration as
specified in subsection 1.2 or subsection 1.12, whichever is applicable.

         1.6   EXPENSES OF DEMAND REGISTRATION. All expenses other than
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications

                                       6
<PAGE>


pursuant to Section 1.2, including (without limitation) all registration,
filing and qualification fees, printers' and accounting fees, fees and
disbursements of counsel for the Company and the fees and disbursements of
one (1) counsel for the selling Holders selected by the Holders of a majority
of the Registrable Securities to be included in such registration shall be
borne by the Company; provided, however, that the Company shall not be
required to pay for any expenses of any registration proceeding begun
pursuant to Section 1.2 if the registration request is subsequently withdrawn
at the request of the Holders of a majority of the Registrable Securities to
be registered (in which case all participating Holders shall bear such
expenses), unless the Holders of a majority of the Registrable Securities
agree to forfeit their right to one demand registration pursuant to Section
1.2; provided further, however, that if at the time of such withdrawal or
failure to close, (a) the Holders proposing to participate in the
registration have learned of a material adverse change in the condition,
business, or prospects of the Company not known to such Holders at the time
of their request and other than a change resulting from market factors or
other matters over which the Company has no control, (b) the facts producing
such change were known to the Company at the time of the request or the
Company's delay in disclosing such facts resulted in substantial additional
expense, and (c) in the case of withdrawal, such Holders have withdrawn the
request with reasonable promptness following disclosure by the Company of
such material adverse change, then such Holders shall not be required to pay
any of such expenses and shall retain their rights pursuant to Section 1.2.
Notwithstanding anything herein to the contrary, any expenses in excess of
$25,000 incurred in connection with any special audit required in connection
with a demand registration pursuant to Section 1.2 shall be borne pro rata by
the selling Holders.

         1.7   EXPENSES OF COMPANY REGISTRATION. The Company shall bear and
pay all expenses incurred in connection with any registration, filing or
qualification of Registrable Securities with respect to the registrations,
other than underwriting discounts and commissions relating to Registrable
Securities, pursuant to Section 1.3 for each Holder (which right may be
assigned as provided in Section 1.13), including (without limitation) all
registration, filing, and qualification fees, printers, and accounting fees
relating or apportionable thereto and the fees and disbursements of one (1)
counsel for the selling Holders selected by them.

         1.8   UNDERWRITING REQUIREMENTS. In connection with any offering
involving an underwriting of shares of the Company's capital stock, the
Company shall not be required under Section 1.3 to include any of the
Holders' Registrable Securities in such underwriting unless they accept the
terms of the underwriting as agreed upon between the Company and the managing
underwriter(s) selected by it (or by other persons entitled to select the
underwriters), and then only in such quantity as the underwriters determine
in their sole discretion will not, jeopardize the success of the offering by
the Company. If the total amount of securities, including Registrable
Securities, requested by shareholders to be included in such offering exceeds
the amount of securities that the underwriters determine in their sole
discretion is compatible with the success of the offering, then the Company
shall be required to include in the offering only that number of such
securities, including Registrable Securities, which the underwriters
determine in their sole discretion will not jeopardize the success of the
offering (the securities so included to be apportioned (a) first, to the
Company, (b) second, pro rata among the selling Holders (other than the
Founders or transferees of the Founders), pro rata according to the total
amount of Registrable


                                       7
<PAGE>


Securities owned by such Holders (c) third, pro rata among the selling
Founders and/or transferees of the Founders according to the total amount of
Registrable Securities owned by each such Holder, and (d) fourth, and to the
extent additional securities may be included therein, pro rata among the
other selling shareholders according to the total amount of Common Stock
owned by each such selling shareholder, or in such other proportions as shall
mutually be agreed to by such selling shareholders); provided, however, that
in no event shall (i) the amount of Registrable Securities of the Holders
(other than the Founders or transferees of the Founders) included in the
offering be reduced below thirty-three percent (33%) of the total amount of
securities included in such offering and (ii) the amount of Registrable
Securities of the Founders and/or transferees of the Founders included in the
offering be reduced below five percent (5%) of the total number of securities
included in such offering, unless such offering is the initial public
offering of the Company's securities in which case the Holders may be
excluded if the underwriters make the determination described above and no
other shareholder's securities are included. For purposes of the preceding
sentence concerning apportionment, for any selling shareholder (i) which is a
holder of Registrable Securities and which is a partnership or corporation,
the partners, retired partners and shareholders of such holder, or the
estates and family members of any such partners and retired partners and any
trusts for the benefit of any of the foregoing persons shall be deemed to be
a single Holder, and (ii) which is an individual, the Relatives or any trusts
for the benefit of the foregoing persons shall be deemed to be a single
Holder. Any pro-rata reduction with respect to such Holder shall be based
upon the aggregate amount of shares carrying registration rights owned by all
entities and individuals included in such Holder, as defined in the preceding
sentence. Furthermore, in each case of (B), (C) and (D) above, any pro rata
apportionment shall be made according to the total amount of Registrable
Securities owned by each applicable Holder at the time of the filing of such
Registration Statement.

         1.9   DELAY OF REGISTRATION. No Holder shall have any right to
obtain or seek an injunction restraining or otherwise delaying any such
registration as the result of any controversy that might arise with respect
to the interpretation or implementation of this Section 1.

         1.10  INDEMNIFICATION. In the event any Registrable Securities are
included in a registration statement under this Section 1:

         (a)   To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, any underwriter (as defined in the Act) for such
Holder and each person, if any, who controls such Holder or underwriter
within the meaning of the Act or the 1934 Act, against any losses, claims,
damages, or liabilities (joint or several) to which they may become subject
under the Act, the 1934 Act or other federal or state law, insofar as such
losses, claims, damages, or liabilities (or actions in respect thereof) arise
out of or are based upon any of the following statements, omissions or
violations (collectively a "Violation"): (i) any untrue statement or alleged
untrue statement of a material fact contained in such registration statement,
including any preliminary prospectus or final prospectus contained therein or
any amendments or supplements thereto and any document incorporated or deemed
incorporated therein by reference, (ii) the omission or alleged omission to
state therein a material fact required to be stated therein, or necessary to
make the statements therein not misleading, or (iii) any violation or alleged
violation by the Company of the Act, the 1934 Act, any state securities law
or any Rule or regulation promulgated under the Act, the 1934 Act or any
state securities law; and the Company will pay to each such Holder,
underwriter or controlling person, as incurred, any legal or other expenses
reasonably incurred by them in connection with investigating or defending any


                                       8
<PAGE>


such loss, claim, damage, liability, or action; provided, however, that the
indemnity agreement contained in this subsection 1.10(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 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
expressly for use in connection with such registration by any such Holder,
underwriter or controlling person; further, that if any losses, claims,
damages or liabilities arise out of or are based upon a Violation which did
not appear in the final prospectus, the Company shall not have any liability
with respect thereto to (i) the Holder or any person who controls such Holder
within the meaning of Section 15 of the Act if the Holder delivered a copy of
the preliminary prospectus to the person alleging such losses, claims,
damages or liabilities and failed to deliver a copy of the final prospectus,
as amended or supplemented if it has been amended or supplemented, to such
person at or prior to the written confirmation of the sale to such person or
(ii) any underwriter or any person who controls such underwriter within the
meaning of Section 15 of the Act, if such underwriter delivered a copy of the
preliminary prospectus to the person alleging such losses, claims, damages or
liabilities and failed to deliver a copy of the final prospectus, as amended
or supplemented, if it has been amended or supplemented, to such person at or
prior to the written confirmation of the sale to such person.

         (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 has signed the registration statement, each person, if any, who
controls the Company within the meaning of the Act, any underwriter, any
other Holder selling securities in such registration statement and any
controlling person of any such underwriter or other Holder, against any
losses, claims, damages, or liabilities (joint or several) to which any of
the foregoing persons may become subject, under the Act, the 1934 Act or
other federal or state law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereto) arise out of or are based upon
any Violation, in each case to the extent (and only to the extent) that such
Violation occurs in reliance upon and in conformity with written information
furnished by such Holder expressly for use in connection with such
registration; and each such Holder will pay, as incurred, any legal or other
expenses reasonably incurred by any person intended to be indemnified
pursuant to this subsection 1.10(b), in connection with investigating or
defending any such loss, claim, damage, liability, or action; provided,
however, that the indemnity agreement contained in this subsection 1.10(b)
shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the
consent of the Holder, which consent shall not be unreasonably withheld;
provided, that, in no event shall any indemnity under this subsection 1.10(b)
exceed the gross proceeds from the offering received by such Holder.

         (c)   Promptly after receipt by an indemnified party under this
Section 1.10 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 1.10,
deliver to the indemnifying party a written notice of the commencement
thereof and the indemnifying party shall have the right to participate in,
and, to the extent the indemnifying party so desires, jointly with any other
indemnifying party similarly noticed, to assume the defense thereof with
counsel mutually satisfactory to the parties; provided, however, that an
indemnified party (together with all other indemnified parties which may be
represented

                                       9
<PAGE>


without conflict by one counsel) shall have the right to retain one separate
counsel, with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential
differing interests between such indemnified party and any other party
represented by such counsel in such proceeding. The failure to deliver
written notice to the indemnifying party within a reasonable time of the
commencement of any such action, if prejudicial to its ability to defend such
action, shall relieve such indemnifying party of any liability to the
indemnified party under this Section 1.10, but the omission so to deliver
written notice to the indemnifying party will not relieve it of any liability
that it may have to any indemnified party otherwise than under this Section
1.10.

         (d)   If the indemnification provided for in this Section 1.10 is
held by a court of competent jurisdiction to be unavailable to an indemnified
party with respect to any loss, liability, claim, damage, or expense referred
to therein, then the indemnifying party, in lieu of indemnifying such
indemnified party hereunder, shall contribute to the amount paid or payable
by such indemnified party as a result of such loss, liability, claim, damage,
or expense in such proportion as is appropriate to reflect the relative fault
of the indemnifying party on the one hand and of the indemnified party on the
other in connection with the statements or omissions that resulted in such
loss, liability, claim, damage, or expense as well as any other relevant
equitable considerations; provided, that, in no event shall any such
contribution under this subsection 1.10(d) exceed the gross proceeds from the
offering received by such indemnifying party. The relative fault of the
indemnifying party and of the indemnified party shall be determined by
reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission to state a material fact relates
to information supplied by the indemnifying party or by the indemnified party
and the parties' relative intent, knowledge, access to information, and
opportunity to correct or prevent such statement or omission.

         (e)   Notwithstanding the foregoing, to the extent that the
provisions on indemnification and contribution contained in the underwriting
agreement entered into in connection with the underwritten public offering
are in conflict with the foregoing provisions, the provisions in the
underwriting agreement shall control.

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

         1.11  REPORTS UNDER SECURITIES EXCHANGE ACT OF 1934. With a view to
making available to the Holders the benefits of Rule 144 promulgated under
the Act and any other Rule or regulation of the SEC that may at any time
permit a Holder to sell securities of the Company to the public without
registration or pursuant to a registration on Form S-3, the Company agrees to:

         (a)   make and keep public information available, as those terms are
understood and defined in SEC Rule 144, at all times after ninety (90) days
after the effective date of the first registration statement filed by the
Company for the offering of its securities to the general public or after the
Company becomes subject to the reporting requirements of the 1934 Act;


                                       10
<PAGE>


         (b)   file with the SEC in a timely manner all reports and other
documents required of the Company under the Act and the 1934 Act; and

         (c)  furnish to any Holder, so long as the Holder owns any
Registrable Securities, forthwith upon request (i) a written statement by the
Company that it has complied with the reporting requirements of SEC Rule 144
(at any time after ninety (90) days after the effective date of the first
registration statement filed by the Company), the Act and the 1934 Act (at
any time after it has become subject to such reporting requirements), 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 which permits the selling of any such securities without registration or
pursuant to such form.

         1.12  FORM S-3 REGISTRATION. In case the Company shall receive from
any Holder or Holders (other than the Officer) 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, use its best efforts to 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 fifteen (15) days after
receipt of such written notice from the Company; provided, however, that the
Company shall not be obligated to effect any such registration, qualification
or compliance, pursuant to this Section 1.12: (1) if Form S-3 is not
available for such offering by the Holders; (2) if the Holders (other than
the Officer), 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 (including any underwriters' discounts or commissions) of
less than $500,000; (3) 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
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 sixty (60) days after receipt of the request of the
Holder or Holders under this Section 1.12; provided, however, that the
Company shall not utilize this right more than once in any twelve (12)-month
period; (4) if the Company has, within the twelve (12)-month period preceding
the date of such request, already effected two (2) registrations on Form S-3
for the Holders pursuant to this Section 1.12; or (5) in any particular
jurisdiction in which the Company would be required to qualify to do business
or to execute a general consent to service of process in effecting such
registration, qualification or compliance unless the Company is already
subject to service in such jurisdiction and except as may be required by the
Act.


                                       11
<PAGE>


         (c)   Subject to the foregoing, the Company shall file a
registration statement covering the Registrable Securities and other
securities so requested to be registered as soon as practicable after receipt
of the request or requests of the Holder or Holders. All expenses incurred in
connection with the first three (3) registrations requested pursuant to this
Section 1.12, including (without limitation) all registration, filing,
qualification, printer's and accounting fees and the reasonable fees and
disbursements of counsel for the selling Holder or Holders and counsel for
the Company, but excluding any underwriters' discounts or commissions
associated with Registrable Securities, shall be borne by the Company.
Registrations effected pursuant to this Section 1.12 shall not be counted as
demands for registration or registrations effected pursuant to Section 1.2.

         1.13  ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the
Company to register Registrable Securities pursuant to this Section 1 may be
assigned (but only with all related obligations) by a Holder to a transferee
or assignee of such securities provided: (a) the Company is, within a
reasonable time after such transfer or assignment, 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
transferred or assigned; (b) such transferee or assignee agrees in writing to
be bound by and subject to the terms and conditions of this Agreement,
including without limitation the provisions of Section 1.15 below; (c) such
transferee or assignee (i) is a stockholder, constituent partner (including
limited partner), Affiliate or Relative of the transferring Holder (or trust
for the benefit of one of the foregoing) and agrees to act through a single
representative with the Holder for the purpose of exercising rights,
receiving notices and taking action hereunder, or (ii) acquires all of the
shares of Registrable Securities held by such Holder or at least one hundred
thousand (100,000) shares of such Registrable Securities (subject to
appropriate adjustment for stock splits, stock dividends, combinations and
other recapitalizations), and (d) such transfer or assignment shall be
effective only if immediately following such transfer or assignment the
further disposition of such securities by the transferee or assignee is
restricted under the Act. Any such transferee or assignee shall be subject to
all rights and obligations hereunder and, if requested by the Company, shall
agree in writing to be bound by the terms of this Agreement.

         1.14  LIMITATIONS ON SUBSEQUENT FIRST REFUSAL AND REGISTRATION RIGHTS.

         (a)   From and after the date of this Agreement, the Company shall
not, without the prior written consent of the Holders of a majority of the
outstanding Registrable Securities (but not including the Registrable
Securities held by the Founders), enter into any agreement with any holder or
prospective holder of any securities of the Company which would (i) allow
such holder or prospective holder (a) to include such securities in any
registration filed under Section 1.2 hereof, unless under the terms of such
agreement, such holder or prospective holder may include such securities in
any such registration only to the extent that the inclusion of its or his
securities will not reduce the amount of the Registrable Securities of the
Holders which is included or (b) to make a demand registration which could
result in such registration statement being declared effective prior to the
earlier of either of the dates set forth in subsection 1.2(a) or within one
hundred twenty (120) days of the effective date of any registration effected
pursuant to Section 1.2; or (ii) give such holder or prospective holder any
"piggy-back" registration rights superior to those provided to the Holders by
Section 1.3 of this Agreement.


                                       12
<PAGE>


         (b)   From and after the date of this Agreement, the Company shall
grant the Holders any registration rights and any rights of first refusal
granted to subsequent purchasers of the Company's equity securities to the
extent that such subsequent rights are superior, in the good faith judgment
of the Board of Directors, to those granted to the Holders by this Agreement.

         1.15  "MARKET STAND-OFF" AGREEMENT. Each Investor, each Founder and
the Officer hereby agrees that, during the period of duration specified by
the Company and the managing underwriter of Common Stock or other securities
of the Company but not to exceed one hundred eighty (180) days, following the
effective date of a registration statement of the Company filed under the
Act, it shall not, to the extent requested by the Company and such
underwriter, directly or indirectly sell, offer to sell, contract to sell
(including, without limitation, any short sale), grant any option to purchase
or otherwise transfer or dispose of (other than to donees who agree to be
similarly bound) any securities of the Company held by it at any time during
such period except Common Stock included in such registration and any
securities acquired in the first registered public offering of the Company's
common stock or in an open market transaction thereafter; provided, however,
that such Holder shall be subject to the market stand-off provisions of this
Section 1.15 only if the officers and directors of the Company are also
subject to similar arrangements.

         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. Notwithstanding the
foregoing, the obligations described in this Section 1.15 shall not apply to
a registration relating solely to employee benefit plans on Form S-1 or Form
S-8 or similar forms which may be promulgated in the future, or a
registration relating solely to a Commission Rule 145 transaction on Form S-4
or a similar form which may be promulgated in the future.

         1.16  TERMINATION OF REGISTRATION RIGHTS.

         (a)   No Holder shall be entitled to exercise any right provided for
in this Section 1 and such Holder's securities shall no longer be deemed to
be Registrable Securities after four (4) years following the consummation of
the first underwritten public offering of shares of Common Stock, registered
under the Securities Act of 1933, as amended, in connection with which the
Company's Series A Preferred Stock, Series B Preferred Stock, Series C
Preferred Stock and Series D Preferred Stock are converted into Common Stock.

         (b)   In addition, the right of any Holder to request registration
or inclusion in any registration pursuant to Section 1.3 shall be terminated
at such time as all of the shares of Registrable Securities held or entitled
to be held upon conversion by such Holder are eligible to be sold under Rule
144 during any ninety (90)-day period, regardless of whether such sale is
otherwise restricted pursuant to any contractual obligations.

         2.    COVENANTS OF THE COMPANY.

         2.1   DELIVERY OF FINANCIAL STATEMENTS AND OTHER INFORMATION. So
long as an Investor and/or an Affiliate thereof continues to own at least

         (e)   provided, however, that the Company shall not be obligated
under any subsection of this Section 2.1 to provide information which it
deems in good faith to be a trade secret.

         2.2   INSPECTION. So long as an Investor (collectively with its
Affiliates) continues to own at least three hundred fifty thousand (350,000)
shares of the Company's Preferred Stock or Common Stock issued upon
conversion thereof, the Company shall permit such Investor, at such
Investor's expense, to visit and inspect the Company's properties, to examine
its books of account and records and to discuss the Company's affairs,
finances and accounts with its officers, all at such reasonable times as may
be requested by the Investor; provided, however, that the Company shall not
be obligated pursuant to this Section 2.2 to provide access to any
information which it reasonably considers to be a trade secret or similar
confidential information.


                                       14
<PAGE>


         2.3   TERMINATION OF INFORMATION AND INSPECTION COVENANTS. The
covenants set forth in Sections 2.1 and 2.2 shall be suspended as to the
Investors and have no force or effect for so long as the Company is subject
to the periodic reporting requirements of Sections 12(g) or 15(d) of the 1934
Act.

         3.    MISCELLANEOUS.

         3.1   SUCCESSORS AND ASSIGNS. Except as otherwise provided herein,
the terms and conditions of this Agreement shall inure to the benefit of and
be binding upon the respective successors and assigns of the parties
(including transferees of any shares of Registrable Securities). Nothing in
this Agreement, express or implied, is intended to confer upon any party

rights, remedies, obligations, or liabilities under or by reason of this
Agreement, except as expressly provided in this Agreement.

         3.2   GOVERNING LAW. This Agreement shall be governed by and
construed under the laws of the State of California as applied to agreements

California.

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

         3.4   TITLES AND SUBTITLES. The titles and subtitles used in this
Agreement are used for convenience only and are not to be considered in

                      1998 STOCK OPTION/STOCK ISSUANCE PLAN
                      -------------------------------------


                                   ARTICLE ONE

                               GENERAL PROVISIONS
                               ------------------

     I.   PURPOSE OF THE PLAN

          This 1998 Stock Option/Stock Issuance Plan is intended to promote
the interests of NetZero, Inc., a California corporation, by providing
eligible persons in the Corporation's employ or service with the opportunity
to acquire a proprietary interest, or otherwise increase their proprietary
interest, in the Corporation as an incentive for them to continue in such
employ or service.

          Capitalized terms herein shall have the meanings assigned to such
terms in the attached Appendix.

     II.   STRUCTURE OF THE PLAN

          A.    The Plan shall be divided into two (2) separate equity
          programs:

                (i)    the Option Grant Program under which eligible
          persons may, at the discretion of the Plan Administrator, be
          granted options to purchase shares of Common Stock, and

                (ii)   the Stock Issuance Program under which eligible
          persons may, at the discretion of the Plan Administrator, be
          issued shares of Common Stock directly, either through the
          immediate purchase of such shares or as a bonus for services
          rendered the Corporation (or any Parent or Subsidiary).

           B.   The provisions of Articles One and Four shall apply to both
equity programs under the Plan and shall accordingly govern the interests of
all persons under the Plan.

     III.  ADMINISTRATION OF THE PLAN

           A.   The Plan shall be administered by the Board. However, any or
all administrative functions otherwise exercisable by the Board may be
delegated to the Committee. Members of the Committee shall serve for such
period of time as the Board may determine and shall be subject to removal by
the Board at any time. The Board may also at any time terminate the functions
of the Committee and reassume all powers and authority previously delegated
to the Committee.

          B.    The Plan Administrator shall have full power and authority
(subject to the provisions of the Plan) to establish such rules and
regulations as it may deem appropriate for proper administration of the Plan
and to make such determinations under, and issue such

interpretations of, the Plan and any outstanding options or stock issuances
thereunder as it may deem necessary or advisable. Decisions of the Plan
Administrator shall be final and binding on all parties who have an interest
in the Plan or any option or stock issuance thereunder.

     IV.  ELIGIBILITY

          A.    The persons eligible to participate in the Plan are as follows:

                (i)    Employees,

                (ii)   non-employee members of the Board or the non-employee
          members of the board of directors of any Parent or Subsidiary, and

                (iii)  consultants and other independent advisors who
          provide services to the Corporation (or any Parent or Subsidiary).

          B.    The Plan Administrator shall have full authority to
determine, (i) with respect to the grants made under the Option Grant
Program, which eligible persons are to receive the option grants, the time or
times when those grants are to be made, the number of shares to be covered by
each such grant, the status of the granted option as either an Incentive
Option or a Non-Statutory Option, the time or times when each option is to
become exercisable, the vesting schedule (if any) applicable to the option
shares and the maximum term for which the option is to remain outstanding,
and (ii) with respect to stock issuances made under the Stock Issuance
Program, which eligible persons are to receive such stock issuances, the time
or times when those issuances are to be made, the number of shares to be
issued to each Participant, the vesting schedule (if any) applicable to the
issued shares and the consideration to be paid by the Participant for such
shares.

          C.    The Plan Administrator shall have the absolute discretion
either to grant options in accordance with the Option Grant Program or to
effect stock issuances in accordance with the Stock Issuance Program.

          V.    STOCK SUBJECT TO THE PLAN

          A.    The stock issuable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock. The maximum number of
shares of Common Stock which may be issued over the term of the Plan shall
not exceed 4,000,000 shares.

          B.    Shares of Common Stock subject to outstanding options shall
be available for subsequent issuance under the Plan to the extent (i) the
options expire or terminate for any reason prior to exercise in full or (ii)
the options are cancelled in accordance with the cancellation-regrant
provisions of Article Two. Unvested shares issued under the Plan and
subsequently repurchased by the Corporation, at the option exercise or direct
issue price paid per share, pursuant to the Corporation's repurchase rights
under the Plan shall be added back to the number of shares of Common Stock
reserved for issuance under the Plan and shall accordingly be available for
reissuance through one or more subsequent option grants or direct stock
issuances under the Plan.

<PAGE>

          C.    Should any change be made to the Common Stock by reason of
any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as
a class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and/or class of
securities issuable under the Plan and (ii) the number and/or class of
securities and the exercise price per share in effect under each outstanding
option in order to prevent the dilution or enlargement of benefits
thereunder. The adjustments determined by the Plan Administrator shall be
final, binding and conclusive. In no event shall any such adjustments be made
in connection with the conversion of one or more outstanding shares of the
Corporation's preferred stock into shares of Common Stock.

                              OPTION GRANT PROGRAM
                              --------------------

     I.   OPTION TERMS

          Each option shall be evidenced by one or more documents in the form
approved by the Plan Administrator; PROVIDED, however, that each such
document shall comply with the terms specified below. Each document
evidencing an Incentive Option shall, in addition, be subject to the
provisions of the Plan applicable to such options.

          A.    EXERCISE PRICE.

                1.     The exercise price per share shall be fixed by the
Plan Administrator in accordance with the following provisions:

                           (i)    The  exercise  price per share shall not be
          less than eighty-five percent (85%) of the Fair Market Value per share
          of Common Stock on the option grant date.

                           (ii)   If the person to whom the option is granted
          is a 10% Shareholder, then the exercise price per share shall not be
          less than one hundred ten percent (110%) of the Fair Market Value per
          share of Common Stock on the option grant date.

                2.     The exercise price shall become immediately due upon
exercise of the option and shall, subject to the provisions of Section I of
Article Four and the documents evidencing the option, be payable in cash or
check made payable to the Corporation. Should the Common Stock be registered
under Section 12 of the 1934 Act at the time the option is exercised, then
the exercise price may also be paid as follows:

                           (i)   in  shares of Common Stock held for the
          requisite period necessary to avoid a charge to the Corporation's
          earnings for financial reporting purposes and valued at Fair Market
          Value on the Exercise Date, or

                           (ii)  to the extent the option is exercised for
          vested shares, through a special sale and remittance procedure
          pursuant to which the Optionee shall concurrently provide
          irrevocable instructions (A) to a Corporation-designated brokerage
          firm to effect the immediate sale of the purchased shares and remit
          to the Corporation, out of the sale proceeds available on the
          settlement date, sufficient funds to cover the aggregate exercise
          price payable for the purchased shares plus all applicable Federal,
          state and local income and employment taxes required to be withheld
          by the Corporation by reason of such exercise and (B) to the
          Corporation to deliver the certificates for the purchased shares
          directly to such brokerage firm in order to complete the sale.

<PAGE>

                           Except to the extent such sale and remittance
procedure is utilized, payment of the exercise price for the purchased
shares must be made on the Exercise Date.

          B.    EXERCISE AND TERM OF OPTIONS. Each option shall be
exercisable at such time or times, during such period and for such number of
shares as shall be determined by the Plan Administrator and set forth in the
documents evidencing the option grant. However, no option shall have a term
in excess of ten (10) years measured from the option grant date.

          C.    EFFECT OF TERMINATION OF SERVICE.

                1.     The following provisions shall govern the exercise
of any options held by the Optionee at the time of cessation of Service or
death:

                           (i)   Should the  Optionee cease to remain in
          Service  for any reason other than death, Disability or Misconduct,
          then the Optionee shall have a period of three (3) months following
          the date of such cessation of Service during which to exercise each
          outstanding option held by such Optionee.

                           (ii)  Should Optionee's Service terminate by
          reason of Disability, then the Optionee shall have a period of
          twelve (12) months following the date of such cessation of Service
          during which to exercise each outstanding option held by such
          Optionee.

                           (iii) If the Optionee dies while holding an
          outstanding option, then the personal representative of his or her
          estate or the person or persons to whom the option is transferred
          pursuant to the Optionee's will or the laws of inheritance shall
          have a twelve (12)-month period following the date of the
          Optionee's death to exercise such option.

                           (iv)  Under no circumstances, however, shall any
          such option be exercisable after the specified expiration of the
          option term.

                           (v)   During the applicable post-Service
          exercise period, the option may not be exercised in the aggregate
          for more than the number of vested shares for which the option is
          exercisable on the date of the Optionee's cessation of Service.
          Upon the expiration of the applicable exercise period or (if
          earlier) upon the expiration of the option term, the option shall
          terminate and cease to be outstanding for any vested shares for
          which the option has not been exercised. However, the option shall,
          immediately upon the Optionee's cessation of Service, terminate and
          cease to be outstanding with respect to any and all option shares
          for which the option is not otherwise at the time exercisable or in
          which the Optionee is not otherwise at that time vested.

                           (vi)  Should Optionee's Service be terminated
          for Misconduct, then all outstanding options held by the Optionee
          shall terminate immediately and cease to remain outstanding.

<PAGE>

                2.     The Plan Administrator shall have the discretion,
exercisable either at the time an option is granted or at any time while the
option remains outstanding, to:

                           (i)   extend the period of time for which the
          option is to remain exercisable following Optionee's
          cessation of Service or death from the limited period otherwise in
          effect for that option to such greater period of time as the Plan
          Administrator shall deem appropriate, but in no event beyond the
          expiration of the option term, and/or

                            (ii)  permit the option to be exercised,
          during the applicable post-Service exercise period, not only with
          respect to the number of vested shares of Common Stock for which
          such option is exercisable at the time of the Optionee's cessation
          of Service but also with respect to one or more additional
          installments in which the Optionee would have vested under the
          option had the Optionee continued in Service.

                D.     SHAREHOLDER RIGHTS. The holder of an option shall have no
shareholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become the
recordholder of the purchased shares.

                E.     UNVESTED SHARES. The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of
Common Stock. Should the Optionee cease Service while holding such unvested
shares, the Corporation shall have the right to repurchase, at the exercise
price paid per share, any or all of those unvested shares. The terms upon
which such repurchase right shall be exercisable (including the period and
procedure for exercise and the appropriate vesting schedule for the purchased
shares) shall be established by the Plan Administrator and set forth in the
document evidencing such repurchase right. The Plan Administrator may not
impose a vesting schedule upon the option grant or any shares of Common Stock
subject to that option which is more restrictive than twenty percent (20%)
per year vesting, with the initial vesting to occur not later than one (1)
year after the option grant date. However, such limitation shall not be
applicable to any option grants made to individuals who are officers of the
Corporation, non-employee Board members or independent consultants.

                F.     FIRST REFUSAL RIGHTS. Until such time as the Common
Stock is first registered under Section 12 of the 1934 Act, the Corporation
shall have the right of first refusal with respect to any proposed
disposition by the Optionee (or any successor in interest) of any shares of
Common Stock issued under the Plan. Such right of first refusal shall be
exercisable in accordance with the terms established by the Plan
Administrator and set forth in the document evidencing such right.

                G.     LIMITED TRANSFERABILITY OF OPTIONS. During the
lifetime of the Optionee, the option shall be exercisable only by the
Optionee and shall not be assignable or transferable other than by will or by
the laws of descent and distribution following the Optionee's death.

                H.     WITHHOLDING. The Corporation's obligation to deliver
shares of Common Stock upon the exercise of any options granted under the
Plan shall be subject to the satisfaction of all applicable Federal, state
and local income and employment tax withholding requirements.

<PAGE>

          II.   INCENTIVE OPTIONS

                The terms specified below shall be applicable to all
Incentive Options. Except as modified by the provisions of this Section II,
all the provisions of the Plan shall be applicable to Incentive Options.
Options which are specifically designated as Non-Statutory Options shall NOT
be subject to the terms of this Section II.

                A.     ELIGIBILITY.  Incentive Options may only be granted to
Employees.

                B.     EXERCISE PRICE. The exercise price per share shall not
be less than one hundred percent (100%) of the Fair Market Value per share of
Common Stock on the option grant date.

                C.     DOLLAR LIMITATION. The aggregate Fair Market Value of
the shares of Common Stock (determined as of the respective date or dates of
grant) for which one or more options granted to any Employee under the Plan
(or any other option plan of the Corporation or any Parent or Subsidiary) may
for the first time become exercisable as Incentive Options during any one (1)
calendar year shall not exceed the sum of One Hundred Thousand Dollars
($100,000). To the extent the Employee holds two (2) or more such options
which become exercisable for the first time in the same calendar year, the
foregoing limitation on the exercisability of such options as Incentive
Options shall be applied on the basis of the order in which such options are
granted.

                D.     10% SHAREHOLDER. If any Employee to whom an Incentive
Option is granted is a 10% Shareholder, then the option term shall not exceed
five (5) years measured from the option grant date.

         III.     CORPORATE TRANSACTION

                A.     The shares subject to each option outstanding under
the Plan at the time of a Corporate Transaction shall automatically vest in
full so that each such option shall, immediately prior to the effective date
of the Corporate Transaction, become fully exercisable for all of the shares
of Common Stock at the time subject to that option and may be exercised for
any or all of those shares as fully-vested shares of Common Stock. However,
the shares subject to an outstanding option shall NOT vest on such an
accelerated basis if and to the extent: (i) such option is assumed by the
successor corporation (or parent thereof) in the Corporate Transaction and
the Corporation's repurchase rights with respect to the unvested option
shares are concurrently assigned to such successor corporation (or parent
thereof) or (ii) such option is to be replaced with a cash incentive program
of the successor corporation which preserves the spread existing on the
unvested option shares at the time of the Corporate Transaction and provides
for subsequent payout in accordance with the same vesting schedule applicable
to those unvested option shares or (iii) the acceleration of such option is
subject to other limitations imposed by the Plan Administrator at the time of
the option grant.

                B.     All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated
rights shall immediately vest in full, in the event of any Corporate
Transaction, except to the extent: (i) those repurchase rights are assigned
to the successor corporation (or parent thereof) in connection with such
Corporate

<PAGE>

Transaction or (ii) such accelerated vesting is precluded by other
limitations imposed by the Plan Administrator at the time the repurchase
right is issued.

                C.     Immediately following the consummation of the
Corporate Transaction, all outstanding options shall terminate and cease to
be outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

                D.     Each option which is assumed in connection with a
Corporate Transaction shall be appropriately adjusted, immediately after such
Corporate Transaction, to apply to the number and class of securities which
would have been issuable to the Optionee in consummation of such Corporate
Transaction, had the option been exercised immediately prior to such
Corporate Transaction. Appropriate adjustments shall also be made to (i) the
number and class of securities available for issuance under the Plan
following the consummation of such Corporate Transaction and (ii) the
exercise price payable per share under each outstanding option, provided the
aggregate exercise price payable for such securities shall remain the same.

                E.     The Plan Administrator shall have the discretion,
exercisable either at the time the option is granted or at any time while the
option remains outstanding, to provide for the automatic acceleration (in
whole or in part) of one or more outstanding options (and the immediate
termination of the Corporation's repurchase rights with respect to the shares
subject to those options) upon the occurrence of a Corporate Transaction,
whether or not those options are to be assumed in the Corporate Transaction.

                F.     The Plan Administrator shall also have full power and
authority, exercisable either at the time the option is granted or at any
time while the option remains outstanding, to structure such option so that
the shares subject to that option will automatically vest on an accelerated
basis should the Optionee's Service terminate by reason of an Involuntary
Termination within a designated period (not to exceed eighteen (18) months)
following the effective date of any Corporate Transaction in which the option
is assumed and the repurchase rights applicable to those shares do not
otherwise terminate. Any option so accelerated shall remain exercisable for
the fully-vested option shares until the EARLIER of (i) the expiration of the
option term or (ii) the expiration of the one (1)-year period measured from
the effective date of the Involuntary Termination. In addition, the Plan
Administrator may provide that one or more of the Corporation's outstanding
repurchase rights with respect to shares held by the Optionee at the time of
such Involuntary Termination shall immediately terminate on an accelerated
basis, and the shares subject to those terminated rights shall accordingly
vest at that time.

                G.     The portion of any Incentive Option accelerated in
connection with a Corporate Transaction shall remain exercisable as an
Incentive Option only to the extent the applicable One Hundred Thousand
Dollar limitation is not exceeded. To the extent such dollar limitation is
exceeded, the accelerated portion of such option shall be exercisable as a
Non-Statutory Option under the Federal tax laws.

                H.     The grant of options under the Plan shall in no way
affect the right of the Corporation to adjust, reclassify, reorganize or
otherwise change its capital or business structure or to merge, consolidate,
dissolve, liquidate or sell or transfer all or any part of its business or
assets.

<PAGE>

          IV.   CANCELLATION AND REGRANT OF OPTIONS

                The Plan Administrator shall have the authority to effect, at
any time and from time to time, with the consent of the affected option
holders, the cancellation of any or all outstanding options under the Plan
and to grant in substitution therefor new options covering the same or
different number of shares of Common Stock but with an exercise price per
share based on the Fair Market Value per share of Common Stock on the new
option grant date.

                             STOCK ISSUANCE PROGRAM
                             ----------------------

          I.    STOCK ISSUANCE TERMS

                Shares of Common Stock may be issued under the Stock Issuance
Program through direct and immediate issuances without any intervening option
grants. Each such stock issuance shall be evidenced by a Stock Issuance
Agreement which complies with the terms specified below.

                A.     PURCHASE PRICE.

                       1.  The  purchase price per share shall be fixed by
the Plan Administrator but shall not be less than eighty-five percent (85%)
of the Fair Market Value per share of Common Stock on the issue date.
However, the purchase price per share of Common Stock issued to a 10%
Shareholder shall not be less than one hundred and ten percent (110%) of such
Fair Market Value.

                       2.  Subject to the provisions of Section I of Article
Four, shares of Common Stock may be issued under the Stock Issuance Program
for any of the following items of consideration which the Plan Administrator
may deem appropriate in each individual instance:

                           (i)   cash or check made payable to the Corporation,
          or

                           (ii)  past services rendered to the Corporation
          (or any Parent or Subsidiary).

                B.     VESTING PROVISIONS.

                       1.     Shares of Common Stock issued under the Stock
Issuance  Program may, in the discretion of the Plan Administrator, be fully
and immediately vested upon issuance or may vest in one or more installments
over the Participant's period of Service or upon attainment of specified
performance objectives. However, the Plan Administrator may not impose a
vesting schedule upon any stock issuance effected under the Stock Issuance
Program which is more restrictive than twenty percent (20%) per year vesting,
with initial vesting to occur not later than one (1) year after the issuance
date. Such limitation shall not apply to any Common Stock issuances made to
the officers of the Corporation, non-employee Board members or independent
consultants.

                       2.     Any new, substituted or additional securities
or other property (including money paid other than as a regular cash
dividend) which the Participant may have the right to receive with respect to
the Participant's unvested shares of Common Stock by reason of any stock
dividend, stock split, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration shall be issued subject to
(i) the same vesting requirements applicable to

<PAGE>

the Participant's unvested shares of Common Stock and (ii) such escrow
arrangements as the Plan Administrator shall deem appropriate.

                       3.     The Participant shall have full shareholder
rights with respect to any shares of Common Stock issued to the Participant
under the Stock Issuance Program, whether or not the Participant's interest
in those shares is vested. Accordingly, the Participant shall have the right
to vote such shares and to receive any regular cash dividends paid on such
shares.

                       4.     Should the Participant cease to remain in
Service while holding one or more invested shares of Common Stock issued
under the Stock Issuance Program or should the performance objectives not be
attained with respect to one or more such unvested shares of Common Stock,
then those shares shall be immediately surrendered to the Corporation for
cancellation, and the Participant shall have no further shareholder rights
with respect to those shares. To the extent the surrendered shares were
previously issued to the Participant for consideration paid in cash or cash
equivalent (including the Participant's purchase-money indebtedness), the
Corporation shall repay to the Participant the cash consideration paid for
the surrendered shares and shall cancel the unpaid principal balance of any
outstanding purchase-money note of the Participant attributable to such
surrendered shares.

                       5.     The Plan Administrator may in its discretion
waive the surrender and cancellation of one or more unvested shares of Common
Stock (or other assets attributable thereto) which would otherwise occur upon
the non-completion of the vesting schedule applicable to such shares. Such
waiver shall result in the immediate vesting of the Participant's interest in
the shares of Common Stock as to which the waiver applies. Such waiver may be
effected at any time, whether before or after the Participant's cessation of
Service or the attainment or non-attainment of the applicable performance
objectives.

                C.    FIRST REFUSAL RIGHTS. Until such time as the Common
Stock is first registered under Section 12 of the 1934 Act, the Corporation
shall have the right of first refusal with respect to any proposed
disposition by the Participant (or any successor in interest) of any shares
of Common Stock issued under the Stock Issuance Program. Such right of first
refusal shall be exercisable in accordance with the terms established by the
Plan Administrator and set forth in the document evidencing such right.

          II.      CORPORATE TRANSACTION

                A.     Upon the occurrence of a Corporate Transaction, all
outstanding repurchase rights under the Stock Issuance Program shall
terminate automatically, and the shares of Common Stock subject to those
terminated rights shall immediately vest in full, except to the extent: (i)
those repurchase rights are assigned to the successor corporation (or parent
thereof) in connection with such Corporate Transaction or (ii) such
accelerated vesting is precluded by other limitations imposed by the Plan
Administrator at the time the repurchase right is issued.

                B.     The Plan Administrator shall have the discretionary
authority, exercisable either at the time the unvested shares are issued or
any time while the Corporation's repurchase rights with respect to those
shares remain outstanding, to provide that those rights shall

<PAGE>

automatically terminate on an accelerated basis, and the shares of Common
Stock subject to those terminated rights shall immediately vest, in the event
the Participant's Service should subsequently terminate by reason of an
Involuntary Termination within a designated period (not to exceed eighteen
(18) months) following the effective date of any Corporate Transaction in
which those repurchase rights are assigned to the successor corporation (or
parent thereof).

          III.  SHARE ESCROW/LEGENDS

                Unvested shares may, in the Plan Administrator's discretion,
be held in escrow by the Corporation until the Participant's interest in such
shares vests or may be issued directly to the Participant with restrictive
legends on the certificates evidencing those unvested shares.

                                  MISCELLANEOUS
                                  -------------

          I.    FINANCING

                The Plan Administrator may permit any Optionee or Participant
to pay the option exercise price or the purchase price for shares issued to
such person under the Plan by delivering a full-recourse, interest-bearing
promissory note payable in one or more installments and secured by the
purchased shares. However, any promissory note delivered by a consultant must

In no event shall the maximum credit available to the Optionee or Participant
exceed the SUM of (i) the aggregate option exercise price or purchase price
payable for the purchased shares plus (ii) any Federal, state and local

Board, but no option granted under the Plan may be exercised, and no shares
shall be issued under the Plan, until the Plan is approved by the
Corporation's shareholders. If such shareholder approval is not obtained
within twelve (12) months after the date of the Board's adoption of the Plan,
then all options previously granted under the Plan shall terminate and cease
to be outstanding, and no further options shall be granted and no shares
shall be issued under the Plan. Subject to such limitation, the Plan
Administrator may grant options and issue shares under the Plan at any time
after the effective date of the Plan and before the date fixed herein for
termination of the Plan.

                B.     The Plan shall terminate upon the EARLIEST of (i) the
expiration of the ten (10)-year period measured from the date the Plan is
adopted by the Board, (ii) the date on which all shares available for
issuance under the Plan shall have been issued as vested shares or (iii) the
termination of all outstanding options in connection with a Corporate
Transaction. All options and unvested stock issuances outstanding at that
time under the Plan shall continue to have full force and effect in
accordance with the provisions of the documents evidencing such options or
issuances.

          III.  AMENDMENT OF THE PLAN

                A.     The Board shall have complete and exclusive power and
authority to amend or modify the Plan in any or all respects. However, no
such amendment or modification shall adversely affect the rights and
obligations with respect to options or unvested stock issuances at the time
outstanding under the Plan unless the Optionee or the Participant consents to
such amendment or modification. In addition, certain amendments may require
shareholder approval pursuant to applicable laws and regulations.

                B.     Options may be granted under the Option Grant Program
and shares may be issued under the Stock Issuance Program which are in each
instance in excess of the number of shares of Common Stock then available for
issuance under the Plan, provided any excess

<PAGE>

shares actually issued under those programs shall be held in escrow until
there is obtained shareholder approval of an amendment sufficiently
increasing the number of shares of Common Stock available for issuance under
the Plan. If such shareholder approval is not obtained within twelve (12)
months after the date the first such excess issuances are made, then (i) any
unexercised options granted on the basis of such excess shares shall
terminate and cease to be outstanding and (ii) the Corporation shall promptly
refund to the Optionees and the Participants the exercise or purchase price
paid for any excess shares issued under the Plan and held in escrow, together
with interest (at the applicable Short Term Federal Rate) for the period the
shares were held in escrow, and such shares shall thereupon be automatically
cancelled and cease to be outstanding.

          IV.   USE OF PROCEEDS

                Any cash proceeds received by the Corporation from the sale
of shares of Common Stock under the Plan shall be used for general corporate
purposes.

          V.    WITHHOLDING

                The Corporation's obligation to deliver shares of Common
Stock upon the exercise of any options or upon the issuance or vesting of any
shares issued under the Plan shall be subject to the satisfaction of all
applicable Federal, state and local income and employment tax withholding
requirements.

          VI.   REGULATORY APPROVALS

                The implementation of the Plan, the granting of any options
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any option or (ii) under the Stock Issuance Program shall be
subject to the Corporation's procurement of all approvals and permits
required by regulatory authorities having jurisdiction over the Plan, the
options granted under it and the shares of Common Stock issued pursuant to it.

          VII.  NO EMPLOYMENT OR SERVICE RIGHTS

                Nothing in the Plan shall confer upon the Optionee or the
Participant any right to continue in Service for any period of specific
duration or interfere with or otherwise restrict in any way the rights of the
Corporation (or any Parent or Subsidiary employing or retaining such person)
or of the Optionee or the Participant, which rights are hereby expressly
reserved by each, to terminate such person's Service at any time for any
reason, with or without cause.

         VIII.  FINANCIAL REPORTS

                The Corporation shall deliver a balance sheet and an income
statement at least annually to each individual holding an outstanding option
under the Plan, unless such individual is a key Employee whose duties in
connection with the Corporation (or any Parent or Subsidiary) assure such
individual access to equivalent information.

                                   ARTICLE ONE

                               GENERAL PROVISIONS

         I.       PURPOSE OF THE PLAN

                  This 1999 Stock Option/Stock Issuance Plan is intended to
promote the interests of NetZero, Inc., a California corporation, by providing
eligible persons in the Corporation's employ or service with the opportunity to
acquire a proprietary interest, or otherwise increase their proprietary
interest, in the Corporation as an incentive for them to continue in such employ
or service.

                  Capitalized terms herein shall have the meanings assigned to
such terms in the attached Appendix.

         II.      STRUCTURE OF THE PLAN

                  A.   The Plan shall be divided into two (2) separate equity
programs:

                                   (i)        the Option Grant Program under
         which eligible persons may, at the discretion of the Plan
         Administrator, be granted options to purchase shares of Common Stock,
         and

                                   (ii)       the Stock Issuance Program under
         which eligible persons may, at the discretion of the Plan
         Administrator, be issued shares of Common Stock directly, either
         through the immediate purchase of such shares or as a bonus for
         services rendered the Corporation (or any Parent or Subsidiary).

                  B.   The provisions of Articles One and Four shall apply to
both equity programs under the Plan and shall accordingly govern the
interests of all persons under the Plan.

         III.     ADMINISTRATION OF THE PLAN

                  A.   The Plan shall be administered by the Board. However, any
or all administrative functions otherwise exercisable by the Board may be
delegated to the Committee. Members of the Committee shall serve for such period
of time as the Board may determine and shall be subject to removal by the Board
at any time. The Board may also at any time terminate the functions of the
Committee and reassume all powers and authority previously delegated to the
Committee.

                  B.   The Plan Administrator shall have full power and
authority (subject to the provisions of the Plan) to establish such rules and
regulations as it may deem appropriate for proper administration of the Plan
and to make such determinations under, and issue such

<PAGE>

interpretations of, the Plan and any outstanding options or stock issuances
thereunder as it may deem necessary or advisable. Decisions of the Plan
Administrator shall be final and binding on all parties who have an interest
in the Plan or any option or stock issuance thereunder.

         IV.      ELIGIBILITY

                  A.   The persons eligible to participate in the Plan are as
follows:

                                   (i)        Employees,

                                   (ii)       non-employee members of the Board
         or the non-employee members of the board of directors of any Parent or
         Subsidiary, and

                                   (iii)      consultants and other independent
         advisors who provide services to the Corporation (or any Parent or
         Subsidiary).

                  B.   The Plan Administrator shall have full authority to
determine, (i) with respect to the grants made under the Option Grant Program,
which eligible persons are to receive the option grants, the time or times when
those grants are to be made, the number of shares to be covered by each such
grant, the status of the granted option as either an Incentive Option or a
Non-Statutory Option, the time or times when each option is to become
exercisable, the vesting schedule (if any) applicable to the option shares and
the maximum term for which the option is to remain outstanding, and (ii) with
respect to stock issuances made under the Stock Issuance Program, which eligible
persons are to receive such stock issuances, the time or times when those
issuances are to be made, the number of shares to be issued to each Participant,
the vesting schedule (if any) applicable to the issued shares and the
consideration to be paid by the Participant for such shares.

                  C.   The Plan Administrator shall have the absolute
discretion either to grant options in accordance with the Option Grant Program
or to effect stock issuances in accordance with the Stock Issuance Program.

         V.       STOCK SUBJECT TO THE PLAN

                  A.   The stock issuable under the Plan shall be shares of
authorized but unissued or reacquired Common Stock. The maximum number of shares
of Common Stock which may be issued over the term of the Plan shall not exceed
8,589,200 shares.

                  B.   Shares of Common Stock subject to outstanding options
shall be available for subsequent issuance under the Plan to the extent (i) the
options expire or terminate for any reason prior to exercise in full or (ii) the
options are cancelled in accordance with the cancellation-regrant provisions of
Article Two. Unvested shares issued under the Plan and subsequently repurchased
by the Corporation, at the option exercise or direct issue price paid per share,
pursuant to the Corporation's repurchase rights under the Plan shall be added
back to the number of shares of Common Stock reserved for issuance under the
Plan and shall accordingly be available for reissuance through one or more
subsequent option grants or direct stock issuances under the Plan.

                                       2

<PAGE>

                  C.   Should any change be made to the Common Stock by reason
of any stock split, stock dividend, recapitalization, combination of shares,
exchange of shares or other change affecting the outstanding Common Stock as a
class without the Corporation's receipt of consideration, appropriate
adjustments shall be made to (i) the maximum number and/or class of securities
issuable under the Plan and (ii) the number and/or class of securities and the
exercise price per share in effect under each outstanding option in order to
prevent the dilution or enlargement of benefits thereunder. The adjustments
determined by the Plan Administrator shall be final, binding and conclusive. In
no event shall any such adjustments be made in connection with the conversion of
one or more outstanding shares of the Corporation's preferred stock into shares
of Common Stock.

                                   (ii)       If the person to whom the option
         is granted is a 10% Shareholder, then the exercise price per share
         shall not be less than one hundred ten percent (110%) of the Fair
         Market Value per share of Common Stock on the option grant date.

                       2.    The exercise price shall become immediately due

         irrevocable instructions (A) to a Corporation-designated brokerage firm
         to effect the immediate sale of the purchased shares and remit to the

         purchased shares plus all applicable Federal, state and local income
         and employment taxes required to be withheld by the Corporation by
         reason of such exercise and (B) to the Corporation to deliver the

                  B.   EXERCISE AND TERM OF OPTIONS. Each option shall be

                                   (iv)       Under no circumstances, however,
         shall any such option be exercisable after the specified expiration of
         the option term.

                                   (v)        During the applicable post-Service
         exercise period, the option may not be exercised in the aggregate for
         more than the number of vested shares for which the option is
         exercisable on the date of the Optionee's cessation of Service. Upon
         the expiration of the applicable exercise period or (if earlier) upon
         the expiration of the option term, the option shall terminate and cease
         to be outstanding for any vested shares for which the option has not
         been exercised. However, the option shall, immediately upon the
         Optionee's cessation of Service, terminate and cease to be outstanding
         with respect to any and all option shares for which the option is not
         otherwise at the time exercisable or in which the Optionee is not
         otherwise at that time vested.

                                   (vi)       Should Optionee's Service be
         terminated for Misconduct, then all outstanding options held by the
         Optionee shall terminate immediately and cease to remain outstanding.

                                       5

                       2.    The Plan Administrator shall have the
discretion, exercisable either at the time an option is granted or at any
time while the option remains outstanding, to:

                                   (i)        extend the period of time for
         which the option is  to remain exercisable following Optionee's
         cessation of Service or death from the limited period otherwise in
         effect for that option to such greater period of time as the Plan
         Administrator shall deem appropriate, but in no event beyond the
         expiration of the option term, and/or

                                   (ii)       permit the option to be exercised,
         during the applicable post-Service exercise period, not only with
         respect to the number of vested shares of Common Stock for which such
         option is exercisable at the time of the Optionee's cessation of
         Service but also with respect to one or more additional installments in
         which the Optionee would have vested under the option had the Optionee
         continued in Service.

                  D.   SHAREHOLDER RIGHTS. The holder of an option shall have no
shareholder rights with respect to the shares subject to the option until such
person shall have exercised the option, paid the exercise price and become the
recordholder of the purchased shares.

                  E.   UNVESTED SHARES. The Plan Administrator shall have the
discretion to grant options which are exercisable for unvested shares of Common
Stock. Should the Optionee cease Service while holding such unvested shares, the
Corporation shall have the right to repurchase, at the exercise price paid per
share, any or all of those unvested shares. The terms upon which such repurchase
right shall be exercisable (including the period and procedure for exercise and
the appropriate vesting schedule for the purchased shares) shall be established
by the Plan Administrator and set forth in the document evidencing such
repurchase right. The Plan Administrator may not impose a vesting schedule upon
the option grant or any shares of Common Stock subject to that option which is
more restrictive than twenty percent (20%) per year vesting, with the initial
vesting to occur not later than one (1) year after the option grant date.
However, such limitation shall not be applicable to any option grants made to
individuals who are officers of the Corporation, non-employee Board members or
independent consultants.

                  F.   FIRST REFUSAL RIGHTS. Until such time as the Common Stock
is first registered under Section 12 of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Optionee (or any successor in interest) of any shares of Common Stock issued
under the Plan. Such right of first refusal shall be exercisable in accordance
with the terms established by the Plan Administrator and set forth in the
document evidencing such right.

                  G.   LIMITED TRANSFERABILITY OF OPTIONS. During the
lifetime of the Optionee, the option shall be exercisable only by the
Optionee and shall not be assignable or transferable other than by will or by
the laws of descent and distribution following the Optionee's death.

                  H.   WITHHOLDING. The Corporation's obligation to deliver
shares of Common Stock upon the exercise of any options granted under the
Plan shall be subject to the satisfaction of all applicable Federal, state
and local income and employment tax withholding requirements.

                                       6

         II.      INCENTIVE OPTIONS

                  The terms specified below shall be applicable to all Incentive
Options. Except as modified by the provisions of this Section II, all the
provisions of the Plan shall be applicable to Incentive Options. Options which
are specifically designated as Non-Statutory Options shall not be subject to the
terms of this Section II.

                  A.   ELIGIBILITY. Incentive Options may only be granted to
Employees.

                  B.   EXERCISE PRICE. The exercise price per share shall not be
less than one hundred percent (100%) of the Fair Market Value per share of
Common Stock on the option grant date.

                  C.   DOLLAR LIMITATION. The aggregate Fair Market Value of the
shares of Common Stock (determined as of the respective date or dates of grant)
for which one or more options granted to any Employee under the Plan (or any
other option plan of the Corporation or any Parent or Subsidiary) may for the
first time become exercisable as Incentive Options during any one (1) calendar
year shall not exceed the sum of One Hundred Thousand Dollars ($100,000). To the
extent the Employee holds two (2) or more such options which become exercisable
for the first time in the same calendar year, the foregoing limitation on the
exercisability of such options as Incentive Options shall be applied on the
basis of the order in which such options are granted.

                  D.   10% SHAREHOLDER. If any Employee to whom an Incentive
Option is granted is a 10% Shareholder, then the option term shall not exceed
five (5) years measured from the option grant date.

         III.     CORPORATE TRANSACTION

                  A.   The shares subject to each option outstanding under the
Plan at the time of a Corporate Transaction shall automatically vest in full so
that each such option shall, immediately prior to the effective date of the
Corporate Transaction, become fully exercisable for all of the shares of Common
Stock at the time subject to that option and may be exercised for any or all of
those shares as fully-vested shares of Common Stock. However, the shares subject
to an outstanding option shall NOT vest on such an accelerated basis if and to
the extent: (i) such option is assumed by the successor corporation (or parent
thereof) in the Corporate Transaction and the Corporation's repurchase rights
with respect to the unvested option shares are concurrently assigned to such
successor corporation (or parent thereof) or (ii) such option is to be replaced
with a cash incentive program of the successor corporation which preserves the
spread existing on the unvested option shares at the time of the Corporate
Transaction and provides for subsequent payout in accordance with the same
vesting schedule applicable to those unvested option shares or (iii) the
acceleration of such option is subject to other limitations imposed by the Plan
Administrator at the time of the option grant.

                  B.   All outstanding repurchase rights shall also terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, in the event of any Corporate Transaction,
except to the extent: (i) those repurchase rights are assigned to the successor
corporation (or parent thereof) in connection with such Corporate

                                       7

<PAGE>

Transaction or (ii) such accelerated vesting is precluded by other limitations
imposed by the Plan Administrator at the time the repurchase right is issued.

                  C.   Immediately following the consummation of the Corporate
Transaction, all outstanding options shall terminate and cease to be
outstanding, except to the extent assumed by the successor corporation (or
parent thereof).

                  D.   Each option which is assumed in connection with a
Corporate Transaction shall be appropriately adjusted, immediately after such
Corporate Transaction, to apply to the number and class of securities which
would have been issuable to the Optionee in consummation of such Corporate
Transaction, had the option been exercised immediately prior to such
Corporate Transaction. Appropriate adjustments shall also be made to (i) the
number and class of securities available for issuance under the Plan
following the consummation of such Corporate Transaction and (ii) the
exercise price payable per share under each outstanding option, provided the
aggregate exercise price payable for such securities shall remain the same.

                  E.   The Plan Administrator shall have the discretion,
exercisable either at the time the option is granted or at any time while the
option remains outstanding, to provide for the automatic acceleration (in whole
or in part) of one or more outstanding options (and the immediate termination of
the Corporation's repurchase rights with respect to the shares subject to those
options) upon the occurrence of a Corporate Transaction, whether or not those
options are to be assumed in the Corporate Transaction.

                  F.   The Plan Administrator shall also have full power and
authority, exercisable either at the time the option is granted or at any time
while the option remains outstanding, to structure such option so that the
shares subject to that option will automatically vest on an accelerated basis
should the Optionee's Service terminate by reason of an Involuntary Termination
within a designated period (not to exceed eighteen (18) months) following the
effective date of any Corporate Transaction in which the option is assumed and
the repurchase rights applicable to those shares do not otherwise terminate. Any
option so accelerated shall remain exercisable for the fully-vested option
shares until the EARLIER of (i) the expiration of the option term or (ii) the
expiration of the one (1)-year period measured from the effective date of the
Involuntary Termination. In addition, the Plan Administrator may provide that
one or more of the Corporation's outstanding repurchase rights with respect to
shares held by the Optionee at the time of such Involuntary Termination shall
immediately terminate on an accelerated basis, and the shares subject to those
terminated rights shall accordingly vest at that time.

                  G.   The portion of any Incentive Option accelerated in
connection with a Corporate Transaction shall remain exercisable as an Incentive
Option only to the extent the applicable One Hundred Thousand Dollar limitation
is not exceeded. To the extent such dollar limitation is exceeded, the
accelerated portion of such option shall be exercisable as a Non-Statutory
Option under the Federal tax laws.

                  H.   The grant of options under the Plan shall in no way
affect the right of the Corporation to adjust, reclassify, reorganize or
otherwise change its capital or business structure or to merge, consolidate,
dissolve, liquidate or sell or transfer all or any part of its business or
assets.

                                       8

         IV.      CANCELLATION AND REGRANT OF OPTIONS

                  The Plan Administrator shall have the authority to effect, at
any time and from time to time, with the consent of the affected option holders,
the cancellation of any or all outstanding options under the Plan and to grant
in substitution therefor new options covering the same or different number of
shares of Common Stock but with an exercise price per share based on the Fair
Market Value per share of Common Stock on the new option grant date.

                             STOCK ISSUANCE PROGRAM


         I.       STOCK ISSUANCE TERMS

                  Shares of Common Stock may be issued under the Stock Issuance
Program through direct and immediate issuances without any intervening option
grants. Each such stock issuance shall be evidenced by a Stock Issuance
Agreement which complies with the terms specified below.

                  A.   PURCHASE PRICE.

                       1.    The purchase price per share shall be fixed by the
Plan Administrator but shall not be less than eighty-five percent (85%) of the
Fair Market Value per share of Common Stock on the issue date. However, the
purchase price per share of Common Stock issued to a 10% Shareholder shall not
be less than one hundred and ten percent (110%) of such Fair Market Value.

                       2.    Subject to the provisions of Section I of Article
Four, shares of Common Stock may be issued under the Stock Issuance Program for
any of the following items of consideration which the Plan Administrator may
deem appropriate in each individual instance:

                                   (i)        cash or check made payable to the
         Corporation, or

                                   (ii)       past services rendered to the
         Corporation (or any Parent or Subsidiary).

                  B.   VESTING PROVISIONS.

                       1.    Shares of Common Stock issued under the Stock
Issuance Program may, in the discretion of the Plan Administrator, be fully
and immediately vested upon issuance or may vest in one or more installments
over the Participant's period of Service or upon attainment of specified
performance objectives. However, the Plan Administrator may not impose a
vesting schedule upon any stock issuance effected under the Stock Issuance
Program which is more restrictive than twenty percent (20%) per year vesting,
with initial vesting to occur not later than one (1) year after the issuance
date. Such limitation shall not apply to any Common Stock issuances made to
the officers of the Corporation, non-employee Board members or independent
consultants.

                       2.    Any new, substituted or additional securities or
other property (including money paid other than as a regular cash dividend)
which the Participant may have the right to receive with respect to the
Participant's unvested shares of Common Stock by reason of any stock
dividend, stock split, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class
without the Corporation's receipt of consideration shall be issued subject to
(i) the same vesting requirements applicable to

                                       10

<PAGE>

the Participant's unvested shares of Common Stock and (ii) such escrow
arrangements as the Plan Administrator shall deem appropriate.

                       3.    The Participant shall have full shareholder
rights with respect to any shares of Common Stock issued to the Participant
under the Stock Issuance Program, whether or not the Participant's interest
in those shares is vested. Accordingly, the Participant shall have the right
to vote such shares and to receive any regular cash dividends paid on such
shares.

                       4.    Should the Participant cease to remain in
Service while holding one or more unvested shares of Common Stock issued
under the Stock Issuance Program or should the performance objectives not be
attained with respect to one or more such unvested shares of Common Stock,
then those shares shall be immediately surrendered to the Corporation for
cancellation, and the Participant shall have no further shareholder rights
with respect to those shares. To the extent the surrendered shares were
previously issued to the Participant for consideration paid in cash or cash
equivalent (including the Participant's purchase-money indebtedness), the
Corporation shall repay to the Participant the cash consideration paid for
the surrendered shares and shall cancel the unpaid principal balance of any
outstanding purchase-money note of the Participant attributable to such
surrendered shares.

                       5.    The Plan Administrator may in its discretion
waive the surrender and cancellation of one or more unvested shares of Common
Stock (or other assets attributable thereto) which would otherwise occur upon
the non-completion of the vesting schedule applicable to such shares. Such
waiver shall result in the immediate vesting of the Participant's interest in
the shares of Common Stock as to which the waiver applies. Such waiver may be
effected at any time, whether before or after the Participant's cessation of
Service or the attainment or non-attainment of the applicable performance
objectives.

                  C.   FIRST REFUSAL RIGHTS. Until such time as the Common Stock
is first registered under Section 12 of the 1934 Act, the Corporation shall have
the right of first refusal with respect to any proposed disposition by the
Participant (or any successor in interest) of any shares of Common Stock issued
under the Stock Issuance Program. Such right of first refusal shall be
exercisable in accordance with the terms established by the Plan Administrator
and set forth in the document evidencing such right.

         II.      CORPORATE TRANSACTION

                  A.   Upon the occurrence of a Corporate Transaction, all
outstanding repurchase rights under the Stock Issuance Program shall terminate
automatically, and the shares of Common Stock subject to those terminated rights
shall immediately vest in full, except to the extent: (i) those repurchase
rights are assigned to the successor corporation (or parent thereof) in
connection with such Corporate Transaction or (ii) such accelerated vesting is
precluded by other limitations imposed by the Plan Administrator at the time the
repurchase right is issued.

                  B.   The Plan Administrator shall have the discretionary
authority, exercisable either at the time the unvested shares are issued or any
time while the Corporation's repurchase rights with respect to those shares
remain outstanding, to provide that those rights shall

                                       11

<PAGE>

automatically terminate on an accelerated basis, and the shares of Common
Stock subject to those terminated rights shall immediately vest, in the event
the Participant's Service should subsequently terminate by reason of an
Involuntary Termination within a designated period (not to exceed eighteen
(18) months) following the effective date of any Corporate Transaction in
which those repurchase rights are assigned to the successor corporation (or
parent thereof).

         III.     SHARE ESCROW/LEGENDS

                  Unvested shares may, in the Plan Administrator's discretion,
be held in escrow by the Corporation until the Participant's interest in such
shares vests or may be issued directly to the Participant with restrictive
legends on the certificates evidencing those unvested shares.

                                       12

                                  MISCELLANEOUS


         I.       FINANCING

                  The Plan Administrator may permit any Optionee or Participant
to pay the option exercise price or the purchase price for shares issued to such
person under the Plan by delivering a full-recourse, interest-bearing promissory
note payable in one or more installments and secured by the purchased shares.
However, any promissory note delivered by a consultant must be secured by
collateral in addition to the purchased shares of Common Stock. In no event
shall the maximum credit available to the Optionee or Participant exceed the
SUM of (i) the aggregate option exercise price or purchase price payable for the
purchased shares plus (ii) any Federal, state and local income and employment
tax liability incurred by the Optionee or the Participant in connection with the
option exercise or share purchase.

         II.      EFFECTIVE DATE AND TERM OF PLAN

                  A.   The Plan shall become effective when adopted by the
Board, but no option granted under the Plan may be exercised, and no shares
shall be issued under the Plan, until the Plan is approved by the
Corporation's shareholders. If such shareholder approval is not obtained
within twelve (12) months after the date of the Board's adoption of the Plan,
then all options previously granted under the Plan shall terminate and cease
to be outstanding, and no further options shall be granted and no shares
shall be issued under the Plan. Subject to such limitation, the Plan
Administrator may grant options and issue shares under the Plan at any time
after the effective date of the Plan and before the date fixed herein for
termination of the Plan.

                  B.   The Plan shall terminate upon the EARLIEST of (i) the
expiration of the ten (10)-year period measured from the date the Plan is
adopted by the Board, (ii) the date on which all shares available for issuance
under the Plan shall have been issued as vested shares or (iii) the termination
of all outstanding options in connection with a Corporate Transaction. All
options and unvested stock issuances outstanding at that time under the Plan
shall continue to have full force and effect in accordance with the provisions
of the documents evidencing such options or issuances.

         III.     AMENDMENT OF THE PLAN

                  A.   The Board shall have complete and exclusive power and
authority to amend or modify the Plan in any or all respects. However, no such
amendment or modification shall adversely affect the rights and obligations with
respect to options or unvested stock issuances at the time outstanding under the
Plan unless the Optionee or the Participant consents to such amendment or
modification. In addition, certain amendments may require shareholder approval
pursuant to applicable laws and regulations.

                  B.   Options may be granted under the Option Grant Program and
shares may be issued under the Stock Issuance Program which are in each instance
in excess of the number of shares of Common Stock then available for issuance
under the Plan, provided any excess

                                       13

<PAGE>

shares actually issued under those programs shall be held in escrow until
there is obtained shareholder approval of an amendment sufficiently
increasing the number of shares of Common Stock available for issuance under
the Plan. If such shareholder approval is not obtained within twelve (12)
months after the date the first such excess issuances are made, then (i) any
unexercised options granted on the basis of such excess shares shall
terminate and cease to be outstanding and (ii) the Corporation shall promptly
refund to the Optionees and the Participants the exercise or purchase price
paid for any excess shares issued under the Plan and held in escrow, together
with interest (at the applicable Short Term Federal Rate) for the period the
shares were held in escrow, and such shares shall thereupon be automatically
cancelled and cease to be outstanding.

         IV.      USE OF PROCEEDS

                  Any cash proceeds received by the Corporation from the sale of
shares of Common Stock under the Plan shall be used for general corporate
purposes.

         V.       WITHHOLDING

                  The Corporation's obligation to deliver shares of Common Stock
upon the exercise of any options or upon the issuance or vesting of any shares
issued under the Plan shall be subject to the satisfaction of all applicable
Federal, state and local income and employment tax withholding requirements.

         VI.      REGULATORY APPROVALS

                  The implementation of the Plan, the granting of any options
under the Plan and the issuance of any shares of Common Stock (i) upon the
exercise of any option or (ii) under the Stock Issuance Program shall be subject
to the Corporation's procurement of all approvals and permits required by
regulatory authorities having jurisdiction over the Plan, the options granted
under it and the shares of Common Stock issued pursuant to it.

         VII.     NO EMPLOYMENT OR SERVICE RIGHTS

                  Nothing in the Plan shall confer upon the Optionee or the
Participant any right to continue in Service for any period of specific duration
or interfere with or otherwise restrict in any way the rights of the Corporation
(or any Parent or Subsidiary employing or retaining such person) or of the
Optionee or the Participant, which rights are hereby expressly reserved by each,
to terminate such person's Service at any time for any reason, with or without
cause.

         VIII.    FINANCIAL REPORTS

                  The Corporation shall deliver a balance sheet and an income
statement at least annually to each individual holding an outstanding option
under the Plan, unless such individual is a key Employee whose duties in
connection with the Corporation (or any Parent or Subsidiary) assure such
individual access to equivalent information.

         price per share of Common Stock on the date in question on the Stock
         Exchange determined by the Plan Administrator to be the primary market
         for the Common Stock, as such price is officially quoted in the
         composite tape of transactions on such exchange. If there is no closing
         selling price for the Common Stock on the date in question, then the
         Fair Market Value shall be the closing selling price on the last
         preceding date for which such quotation exists.

                        (iii)  If the Common Stock is at the time neither listed
         on any Stock Exchange nor traded on the Nasdaq National Market, then
         the Fair Market Value shall be determined by the Plan Administrator

         provided and only if such change, reduction or relocation is effected
         without the individual's consent.

fraud, embezzlement or dishonesty by the Optionee or Participant, any

                        DIRECTOR'S INDEMNIFICATION AGREEMENT


     THIS DIRECTOR'S INDEMNIFICATION AGREEMENT ("Agreement") is made and
entered into as of        , 1999 by and between NetZero, Inc., a Delaware
corporation (the "Company"), and                 ("Director").

                                  R E C I T A L S

          A.   Director, as the [              ] and a member of the Board of
Directors of the Company, performs a valuable service in such capacity for
the Company;

          B.   The stockholders of the Company have adopted Bylaws (the
"Bylaws") providing for the indemnification of the officers, directors,
agents and employees of the Company to the maximum extent authorized by
Section 145 of the Delaware General Corporation Law, as amended (the
"Delaware Law");

          C.   The Bylaws and the Delaware Law, by their non-exclusive
nature, permit contracts between the Company, its officers and the members of
its Board of Directors with respect to indemnification of such persons;

          D.   In accordance with the authorization as provided by the
Delaware Law, the Company has purchased and presently maintains or will
shortly hereafter purchase and thereafter maintain, a policy or policies of
directors and officers liability insurance ("D & O Insurance"), covering
certain liabilities which may be incurred by its directors and officers in
the performance as directors of the Company;

          E.   As a result of developments affecting the terms, scope and
availability of D & O Insurance, there exists general uncertainty as to the
extent of protection afforded members of the Board of Directors and officers
of the Company by such D & O Insurance and by statutory and Bylaw
indemnification provisions; and

          F.   In order to induce Director to continue to serve as
[an executive officer and] a member of the Board of Directors of the Company,
the Company has determined and agreed to enter into this contract with
Director.

          NOW, THEREFORE, in consideration of Director's continued service to
the Company after the date hereof, the parties hereto agree as follows:

          1.   INDEMNITY OF DIRECTOR.  The Company hereby agrees to hold
harmless and indemnify Director to the fullest extent authorized or permitted
by the provisions of the Delaware Law, as may be amended from time to time,
and by the Bylaws as they exist as of the date hereof.

          2.   ADDITIONAL INDEMNITY.  Subject only to the exclusions set
forth in Section 3 hereof, the Company hereby further agrees to hold harmless
and indemnify Director:

<PAGE>

               (a)  against any and all expenses (including reasonable
attorneys' fees), witness fees, judgments, fines and amounts paid in
settlement actually and reasonably incurred by Director in connection with
any threatened, pending or completed action, suit or proceeding, whether
civil, criminal, administrative or investigative (including an action by or
in the right of the Company) to which Director is, was or at any time becomes
a party, or is threatened to be made a party, by reason of the fact that
Director is or was an officer or director of the Company, or is or was
serving or at any time serves at the request of the Company as an officer or
director of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise; and

               (b)  otherwise to the fullest extent as may be provided to
Director by the Company under the non-exclusivity provisions of Section 5 of
Article VIII of the Bylaws of the Company.

          3.   LIMITATIONS ON ADDITIONAL INDEMNITY.  No indemnity pursuant to
Section 2 hereof shall be paid by the Company:

               (a)  except to the extent the aggregate of losses to be
indemnified thereunder exceeds the sum of such losses for which the Director
is indemnified pursuant to Section 1 hereof or pursuant to any directors and
officers liability insurance purchased and maintained by the Company;

               (b)  in respect to remuneration paid to Director if it shall
be determined by a final judgment or other final adjudication that such
remuneration was in violation of law;

               (c)  on account of any suit in which judgment is rendered
against Director for an accounting of profits, made from the purchase or sale
by Director of securities of the Company, pursuant to the provisions of
Section 16(b) of the Securities Exchange Act of 1934 and amendments thereto
or similar provisions of any federal, state or local statutory law;

               (d)  on account of Director's conduct which is finally
adjudged to have been knowingly fraudulent or deliberately dishonest, or to
constitute willful misconduct;

               (e)  on account of Director's conduct which is the subject of
an action, suit or proceeding described in Section 7(c)(ii) hereof;

               (f)  on account of any action, claim or proceeding (other than
a proceeding referred to in Section 8(b) hereof) initiated by the Director
unless such action, claim or proceeding was authorized in the specific case
by action of the Board of Directors; and

               (g)  if a final decision by a court having jurisdiction in the
matter shall determine that such indemnification is not lawful (and, in this
respect, both the Company and Director have been advised that the Securities
and Exchange Commission believes that indemnification for liabilities arising
under the federal securities laws is against public policy and is, therefore,
unenforceable and that claims for indemnification should be submitted to
appropriate courts for adjudication).

                                       2
<PAGE>

          4.   CONTRIBUTION.  If the indemnification provided in Sections 1
and 2 hereof is unavailable by reason of a court decision described in
Section 3(g) hereof based on grounds other than any of those set forth in
paragraphs (b) through (f) of Section 3 hereof, then in respect of any
threatened, pending or completed action, suit or proceeding in which the
Company is jointly liable with Director (or would be if joined in such
action, suit or proceeding), the Company shall contribute to the amount of
expenses (including reasonable attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred and paid or payable by
Director in such proportion as is appropriate to reflect (i) the relative
benefits received by the Company on the one hand and Director on the other
hand from the transaction from which such action, suit or proceeding arose,
and (ii) the relative fault of the Company on the one hand and of Director on
the other in connection with the events which resulted in such expenses,
judgments, fines or settlement amounts, as well as any other relevant
equitable considerations. The relative fault of the Company on the one hand
and of Director on the other shall be determined by reference to, among other
things, the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent the circumstances resulting in such
expenses, judgments, fines or settlement amounts. The Company agrees that it
would not be just and equitable if contribution pursuant to this Section 4
were determined by pro rata allocation or any other method of allocation
which does not take account of the foregoing equitable considerations.

          5.   CONTINUATION OF OBLIGATIONS.  All agreements and obligations
of the Company contained herein shall continue during the period Director is
an executive officer or director of the Company (or is or was serving at the
request of the Company as an executive officer or director of another
corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise) and shall continue thereafter so long as Director shall be
subject to any possible claim or threatened, pending or completed action,
suit or proceeding, whether civil, criminal or investigative, by reason of
the fact that Director was an executive officer or director of the Company or
serving in any other capacity referred to herein.

          6.   NOTIFICATION AND DEFENSE OF CLAIM.  Not later than thirty (30)
days after receipt by Director of notice of the commencement of any action,
suit or proceeding, Director will, if a claim in respect thereof is to be
made against the Company under this Agreement, notify the Company of the
commencement thereof, but the omission so to notify the Company will not
relieve the Company from any liability which it may have to Director
otherwise than under this Agreement. With respect to any such action, suit or
proceeding as to which Director notifies the Company of the commencement
thereof:

               (a)  the Company will be entitled to participate therein at
its own expense;

               (b)  except as otherwise provided below, to the extent that it
may wish, the Company jointly with any other indemnifying party similarly
notified will be entitled to assume the defense thereof, with counsel
reasonably satisfactory to Director.  After notice from the Company to
Director of its election so as to assume the defense thereof, the Company
will not be liable to Director under this Agreement for any legal or other
expenses subsequently

                                       3
<PAGE>

incurred by Director in connection with the defense thereof other than
reasonable costs of investigation or as otherwise provided below.  Director
shall have the right to employ its counsel in such action, suit or
proceeding, but the fees and expenses of such counsel incurred after notice
from the Company of its assumption of the defense thereof shall be at the
expense of Director unless (i) the employment of counsel by Director has been
authorized by the Company, (ii) Director shall have reasonably concluded,
based on the advice of counsel, that there may be a conflict of interest
between the Company and Director in the conduct of the defense of such action
or (iii) the Company shall not in fact have employed counsel to assume the
defense of such action, in each of which cases the fees and expenses of
Director's separate counsel shall be at the expense of the Company.  The
Company shall not be entitled to assume the defense of any action, suit or
proceeding brought by or on behalf of the Company or as to which Director
shall have made the conclusion provided for in (ii) above; and

               (c)  the Company shall not be liable to indemnify Director
under this Agreement for any amounts paid in settlement of any action or
claim effected without its written consent.  Company shall be permitted to
settle any action except that it shall not settle any action or claim in any
manner which would impose any penalty or limitation on Director without
Director's written consent.  Neither the Company nor Director will
unreasonably withhold its consent to any proposed settlement.

          7.   ADVANCEMENT AND REPAYMENT OF EXPENSES.

               (a)  In the event that Director employs his own counsel
pursuant to Section 6(b)(i) through (iii) above, the Company shall advance to
Director, prior to any final disposition of any threatened or pending action,
suit or proceeding, whether civil, criminal, administrative or investigative,
any and all reasonable expenses (including legal fees and expenses) incurred
in investigating or defending any such action, suit or proceeding within ten
(10) days after receiving copies of invoices presented to Director for such
expenses.

               (b)  Director agrees that Director will reimburse the Company
for all reasonable expenses paid by the Company in defending any civil or
criminal action, suit or proceeding against Director in the event and only to
the extent it shall be ultimately determined by a final judicial decision
(from which there is no right of appeal) that Director is not entitled, under
the provisions of the Delaware Law, the Bylaws, this Agreement or otherwise,
to be indemnified by the Company for such expenses.

               (c)  Notwithstanding the foregoing, the Company shall not be
required to advance such expenses to Director if Director (i) commences any
action, suit or proceeding as a plaintiff unless such advance is specifically
approved by a majority of the Board of Directors or (ii) is a party to an
action, suit or proceeding brought by the Company and approved by a majority
of the Board which alleges willful misappropriation of corporate assets by
Director, wilfull disclosure of confidential information in bad faith and in
violation of Director's fiduciary or contractual obligations to the Company,
or any other willful and deliberate breach in bad faith of Director's duty to
the Company or its stockholders.

                                       4
<PAGE>

          8.   ENFORCEMENT.

               (a)  The Company expressly confirms and agrees that it has
entered into this Agreement and assumed the obligations imposed on the
Company hereby in order to induce Director to continue as a director of the
Company, and acknowledges that Director is relying upon this Agreement in
continuing in such capacity.

               (b)  In the event Director is required to bring any action to
enforce rights or to collect moneys due under this Agreement and is
successful in such action, the Company shall reimburse Director for all
Director's reasonable fees and expenses in bringing and pursuing such action.

          9.   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 Director, who shall execute all documents required and
shall do all acts that may be necessary to secure such rights and to enable
the Company effectively to bring suit to enforce such rights.

          10.  NON-EXCLUSIVITY OF RIGHTS.  The rights conferred on Director
by this Agreement shall not be exclusive of any other right which Director
may have or hereafter acquire under any statute, provision of the Company's
Certificate of Incorporation or Bylaws, agreement, vote of stockholders or
directors, or otherwise, both as to action in his official capacity and as to
action in another capacity while holding office.

          11.  SURVIVAL OF RIGHTS.  The rights conferred on Director by this
Agreement shall continue after Director has ceased to be a director, officer,
employee or other agent of the Company and shall inure to the benefit of
Director's heirs, executors and administrators.

          12.  SEVERABILITY.  Each of the provisions of this Agreement is a
separate and distinct agreement and independent of the others, so that if any
or all of the provisions hereof shall be held to be invalid or unenforceable
for any reason, such invalidity or unenforceability shall not affect the
validity or enforceability of the other provisions hereof or the obligation
of the Company to indemnify the Director to the full extent provided by the
Bylaws or the Delaware Law.

          13.  GOVERNING LAW; VENUE AND JURISDICTION.  This Agreement shall
be interpreted and enforced in accordance with the laws of the State of
Delaware, without regard to the conflicts of law provisions thereof.  The
Company and Director hereby irrevocably and unconditionally (i) agree that
any action or proceeding arising out of or in connection with this Agreement
shall be brought only in the Court of Chancery of the State of Delaware (the
"Delaware Court"), and not in any other State or federal court in the United
States of America or any court in any other country, (ii) consent to submit
to the exclusive jurisdiction of the Delaware Court for purposes of any
action or proceeding arising out of or in connection with this Agreement,
(iii) waive any objection to the laying of venue of any such action or
proceeding in the Delaware Court, and (iv) waive, and agree not to plead or
to make, any claim that any such action or proceeding brought in the Delaware
Court has been brought in an improper or otherwise inconvenient forum.

                                       5
<PAGE>

          14.  BINDING EFFECT.  This Agreement shall be binding upon Director
and upon the Company, its successors and assigns, and shall inure to the
benefit of Director, his heirs, personal representatives and assigns and to
the benefit of the Company, its successors and assigns.

          15.  AMENDMENT AND TERMINATION.  No amendment, modification,
termination or cancellation of this Agreement shall be effective unless in
writing signed by both parties hereto.

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement
on and as of the day and year first above written.
