                               iBEAM BROADCASTING

   We provide an Internet broadcast network that delivers streaming media to
large audiences of simultaneous users with viewing and listening quality that
can approach that of television and radio. Streaming is a media distribution
process that allows simultaneous broadcasting and playback of video and audio
content. Our network uses a combination of land-line networks and point-to-
multipoint satellite broadcasting, which is the use of satellite technology to
broadcast streaming content simultaneously to large, geographically dispersed
audiences. Our network is designed to broadcast directly to iBEAM servers
located at the edge of Internet, the Internet access point closest to the end
user. This improves the quality of the broadcast stream by avoiding Internet
congestion. Our network broadcasts to iBEAM servers located in the facilities
of Internet service providers, or ISPs, and other companies that host Internet
applications and services.

   We provide a wide range of services to our content provider customers to
facilitate their use of streaming media on the Internet, including event
production and broadcasting services. To expand our service offerings to our
customers, we have acquired and developed software and interface tools that
enable us to broadcast high-fidelity video and audio streams integrated with e-
commerce links and functions. Our investment in servers at the edge of the
Internet will also allow for the development of new value-added services in the
future, such as pay-per-view event programming, advertising to targeted end
users and interactive Internet-based training.

   The Internet was not designed to support the traffic load created by
broadcasting full-motion video or high-fidelity audio simultaneously to large
audiences. Users, however, are investing in high-speed Internet connections to
their homes and businesses, such as digital subscriber lines, or DSL, and cable
modems, to improve their viewing and listening quality and are increasing the
traffic load on the Internet causing web congestion and degradation of viewing
and listening quality. Despite these limitations, existing websites,
traditional media companies, new media companies and creators of new
applications, such as online education, are aggressively trying to attract and
retain Internet users by using greater amounts of streaming audio-visual
content. The Gartner Group projects that approximately 50% of websites will
include some streaming media by 2001, a five-fold increase from 1998. Our
approach of using a combination of land-line networks and satellite
broadcasting to deliver content directly to the edge of the Internet bypasses
much of the web congestion and improves the delivery of streaming audio-visual
media and the quality of the viewing and listening experience.

   In April 2000, we acquired webcasts.com to add business-to-business
communications capabilities, such as online training and interactive trade
shows. Our combined technology allows users to view streaming content,
interactively obtain related data and transact online purchases. Our technology
runs with a variety of streaming media players, which are software applications
designed to run streaming media. Most Internet users can access our streamed
content regardless of their multimedia and browsing software so they do not
need to purchase special equipment. As of March 31, 2000, our network, which we
will continue to develop, is sufficient to support up to 300,000 simultaneous
Internet users accessing streams of data from the Internet at 20 kilobits
(20,000 bits) per second. We plan to expand our network to support 1,000,000
simultaneous Internet users at this rate by the end of 2000.

   We commercially introduced our service in October 1999. We currently have
contracts to provide our services to over 100 content providers. We generate
revenue from our broadcasting services based on the volume of content stored or
delivered to end users and from our other services such as encoding and event
production

                                       3
<PAGE>


based on hourly or fixed price billing. We derived 74% of our revenue from our
event-based on-stage services during 1999 and 25% of our revenue from these
services for the three months ended March 31, 2000.

   As part of the build-out of our broadcasting network, we have agreements to
locate servers with over 90 ISPs, including America Online, the largest U.S.
Internet access provider, Excite@Home, an Internet cable access provider, and
Covad Communications and Northpoint, high-speed Internet access providers that
have developed networks with national reach. Our ability to provide content
providers with high quality, low-cost distribution of streaming video and audio
content is dependent on deployment of our servers in the facilities of ISPs. To
realize the benefits of these access agreements with ISPs we will need to
invest at least $15.0 million in capital equipment located at ISPs during 2000
and pay some ISPs fees ranging from 15 to 20% of the revenue we derive from
content delivered through their networks. We have agreed to make non-refundable
prepayments to ISPs in the amount of $5.5 million, of which $3.0 million has
been paid as of March 31, 2000. We do not generate any revenue from our
agreements with ISPs. In January 2000, we entered into a letter of intent with
Pacific Century CyberWorks, or PCCW, to establish a joint venture, named iBEAM
Asia, to expand our international presence in the Pacific Rim, Indian
subcontinent and Middle East.

Business Strategy

   Our goal is to become the leading provider of high-fidelity Internet
broadcast services by developing the world's largest, premier quality and most
cost efficient distributed streaming network. To this end, we are capitalizing
upon our innovative network architecture, proprietary technology and early
entry into the field of streaming media broadcasting to position ourselves as
the network of choice for reliable, high-fidelity Internet broadcasting. Our
strategy comprises the following initiatives:

  .  Expand our customer base by increasing our direct sales force and
     engaging in business-to-business advertising;

  .  Offer cost savings to our customers based on the economic benefit of
     broadcasting to large audiences;

  .  Introduce new services such as integrating streaming media with online
     chat and purchasing capabilities which we will obtain through our
     acquisition of webcasts.com;

  .  Pursue joint ventures that expand our global presence, such as iBEAM
     Asia, and add new capabilities to our network; and

  .  Offer our streaming distribution technology to other network vendors to
     create an industry standard.

Risk Factors

   We are in an early stage of development, have a limited operating history
and have generated limited revenue to date. In addition, investors in our
common stock should consider the following:

  .  We had operating losses of $4.4 million in 1998, $30.2 million in 1999
     and $21.7 million for the first quarter of 2000.

  .  We anticipate incurring substantial operating losses and negative cash
     flow in the foreseeable future.

  .  Management and affiliates will beneficially own 37.5% of our outstanding
     common stock after this offering.

  .  We had an accumulated deficit of $66.3 million as of March 31, 2000.

  .  We operate in a highly competitive industry.

  .  We will need to serve an increasing percentage of Internet users from
     the edge of our network for our business strategy to succeed.

                                 RISK FACTORS

   You should consider carefully the following risks before you decide to buy
our common stock. If any of the following risks actually materializes, our
business, financial condition or results of operations would likely suffer. In
such case, the trading price of our common stock could fall, and you could
lose all or part of the money paid to buy our common stock.

Risks Related to Our Business

   Because we are a development stage company that has generated limited
revenues and only recently began offering our services in October 1999, our
business and prospects are unproven and difficult to evaluate.

   We were founded in March 1998 and began offering our Internet broadcasting
services for streaming video and audio in October 1999. The revenue and income
potential of our services and business and the size of our market are
unproven. We have limited meaningful historical financial data upon which to
base planned operating expenses and upon which investors may evaluate us and
our prospects. In addition, our operating expenses are largely based on
anticipated revenue trends and a high percentage of our expenses are and will
continue to be fixed for the foreseeable future. Accordingly, we are subject
to all of the risks that are associated with companies in an emerging industry
and in an early stage of development, particularly companies in the rapidly
evolving Internet infrastructure market, including:

  .  Undercapitalization;

  .  Cash shortages;

  .  The unproven nature of our business plan;

  .  The new and unproven nature of the market for our services;

  .  The need to make significant expenditures and incur significant expenses
     as we develop our business and network;

  .  The lack of sufficient clients and revenues to sustain our operations
     and growth without additional financing;

  .  Difficulties in managing growth including integration of the
     webcasts.com business into our business; and

  .  Limited experience in providing some of the services that we offer or
     plan to offer.

If we are unsuccessful in addressing these risks, our business may be
seriously harmed.

   We are entirely dependent on our Internet broadcasting services and our
future revenue depends on their commercial success.

   Our future revenue growth depends on the commercial success of our Internet
broadcasting services. We have recently begun to commercially introduce our
services for the delivery of streaming video and audio, and our future revenue
growth will depend upon customer demand for these services. Failure of our
current and planned services to operate as expected or the occurrence of any
service interruptions or technical problems with our network could delay or
prevent customer acceptance of our services. If our target customers do not
adopt and purchase our current and planned services, our revenue will not grow
significantly and we may not become profitable as a result.

   Our business strategy is based on our ability to build our broadcast
network to the edge of the Internet, which is dependent on our relationship
with Internet service providers.

   Our business strategy is dependent on our ability to build our broadcast
network to the edge of the Internet, which is the access point closest to the
end user. Our ability to provide content providers with high quality, low-cost
distribution of streaming video and audio content is dependent on the
development of an edge network. The development of our edge network requires
that we locate our servers in the facilities of ISPs, which control the
Internet access points closest to the end user. As of March 31, 2000, we had
servers at 65 locations on the edge of the Internet and we estimate that as of
this date we were serving less than 5% of traffic delivered through our
network from the edge of the Internet. By the end of 2000, we expect we will
be able to serve up to 40% of the traffic on our network through our servers
located at the edge of the Internet. In order to achieve this deployment we
estimate that we will need to make at least $15.0 million in capital
expenditures for edge servers in 2000. We may choose to accelerate the
deployment of our network or increase expenditures relating to our network.

   To accomplish our business strategy, we will need to deploy our edge
servers in the facilities of Internet service providers. Although we provide
Internet service providers with our servers at no cost, Internet service
providers may nevertheless refuse to allow us to install our equipment in
their facilities. If we are unable to further develop our edge network, our
costs may increase and our services may not eliminate packet loss and jitter,
resulting in poor quality service. If the quality of our services suffers we
may lose or fail to obtain customers, which would harm our revenues.
Therefore, our failure to deploy our edge servers close to the end user will
cause our business and results of operations to suffer greatly. The
development of our edge network will require that we not only enter into
additional agreements with ISPs to locate our servers in their facilities, but
also that we successfully move content from our hosting centers to our edge
servers such that we serve end users from the edge.

   Our agreements with larger ISPs are critical to the success of our business
plan because through these agreements we gain access to large numbers of end
users that we can reach through our satellite distribution network rather than
through land-lines. Our agreements with high speed Internet access providers
are important because through these agreements we can reach Internet users
with high-speed or "broadband" connections from the edge of the Internet.
These users tend to access greater volumes of streaming content. Unless we can
reach large numbers of Internet users through our edge network, our services
will not be attractive to content providers. In order to secure agreements
with large ISPs and high speed Internet access providers, in some instances we
have agreed to share between 15% and 20% of the revenue we derive from content
delivered through their networks. We have also agreed to make non-refundable
prepayments to ISPs in the amount of $5.5 million, of which $3.0 million has
been paid as of March 31, 2000.

   Our agreement with America Online provides that we will deploy our servers
in America Online's facilities in North America. Considering the reach of
America Online's network and market position as the leading provider of
Internet access in the United States, our agreement with America Online is
critical to our strategy of delivering more content to the edge of the
Internet. The agreement will increase the availability of content delivered
through our network on the edge of the Internet. The agreement with America
Online has an initial two year term, but may be terminated by either party for
material breach by the other upon 30 days notice. In addition, in the first
year of the agreement America Online has the right to terminate the agreement
if we do not deliver a required level of Internet content through their
network. A termination of, or adverse change in, our relationship with America
Online would seriously impair our efforts to establish and maintain an
Internet broadcast network that can reach most U.S. Internet users.

   Our agreement with Excite@Home provides that we will deploy our servers in
Excite@Home national data centers upon Excite@Home's completion of their
centers. Considering Excite@Home's position as a provider of high-speed
Internet access though cable access, our agreement is important to the
development of our network on the edge of the Internet. The agreement has a
three year term. Either party may terminate the agreement with 30 days notice
upon a material default by the other. Excite@Home may terminate the agreement
upon 30 days notice upon a change of control of iBEAM. In addition,
Excite@Home may terminate the agreement without cause after two years. A
termination of, or adverse change in, our relationship with Excite@Home would

                                       8
<PAGE>

seriously impair our efforts to establish an Internet broadcast network that
can broadcast to the edge of the Internet.

   Our agreement with Covad provides that we will deploy our servers in
Covad's network, which is in North America. Considering the size of Covad's
network and market position as a provider of broadband access using digital
subscriber line, or DSL, technology, our agreement is important to the
deployment of our edge servers. Within the first year of our agreement with
Covad, either party may terminate the agreement upon 60 days notice. During
the second and third years of the agreement, either party may terminate the
agreement upon a material breach by the other. A termination of, or adverse
change in, our relationship with Covad could harm our efforts to deploy our
edge servers and our ability to develop new technologies that complement our
existing service offerings.

   Our agreement with Northpoint provides that we will deploy our services in
Northpoint's network, which is in North America. Considering the size of
Northpoint's network and market position as a provider of broadband access,
our agreement is important to the deployment of our edge servers. The
agreement has a three year term and is terminable by either party upon 60 days
notice in the first year of the agreement. In the second and third years of
the agreement, either party may terminate the agreement due to a material
breach by the other. A termination of, or adverse change in, our relationship
with Northpoint could harm our efforts to deploy our edge servers.

   Because our Internet broadcasting network is complex and is deployed in
complex environments, it may have errors or defects that could seriously harm
our business.

   Our Internet broadcasting network is highly complex and is deployed in
complex environments. Because of the nature of our services, we can only fully
test it when it is fully deployed in very large networks with high traffic
volumes. Given the current early stage of deployment of our network, we cannot
test it for all possible defects. However, as a result of testing conducted to
date, we and our customers have from time to time discovered errors and
defects in our software. Since we commenced offering our services in October
1999, we have experienced two network outages, one of which was due to failure
of our network software. We may continue to experience problems with our
software. Outages that have occurred to date have resulted in between one and
five hours of network downtime during which time we were prevented from
delivering our services to our customers. These downtimes resulted in lost
revenues for usage not billed during down periods.

   In the future, there may be additional errors and defects in our software
and servers that may adversely affect our service. If we are unable to
efficiently fix errors or other problems that may be identified, we could
experience:

  .  Loss of or delay in sales and loss of market share;

  .  Loss of customers;

  .  Failure to attract new customers or achieve market acceptance;

  .  Diversion of development resources;

  .  Loss of credibility;

  .  Increased service costs; or

  .  Legal action by our customers.

   Any failure of our network infrastructure or the satellite or land-line
communication services provided to us could lead to significant costs and
disruptions which could harm our reputation and cause us to lose customers,
which would have a negative impact on our revenues.

   Our business and reputation are dependent on providing our customers with
high-fidelity and low-cost Internet broadcasting services through our network.
To meet these customer requirements, we must protect our network
infrastructure against damage from:

  .  Human error;

  .  Network software errors;

                                       9
<PAGE>

  .  Physical or electronic security breaches;

  .  Fire, earthquake, flood and other natural disasters;

  .  Power loss; and

  .  Sabotage and vandalism.

   Our costs are generally higher and quality of service is generally lower
when we deliver content to end users from our hosting centers rather than our
edge servers. As a result, the occurrence of any of the unanticipated problems
listed above at one or more of our edge servers could result in service
interruptions or significant damage to equipment, increase our costs and cause
a degradation in the quality of our services. Further, if we are unable to
provide our network services to our customers, we could face legal action by
our customers, which would be costly and divert management's attention from
important business activities. Because our servers are located in the
facilities of others, such as Internet service providers and Internet hosting
companies, we must rely on others to protect our equipment.

   Our network architecture uses satellite transmission to bypass the
congestion of the Internet backbone by broadcasting directly to our edge
servers. We have entered into a three-year agreement with a satellite service
provider for transmission capacity over a specified satellite. While the
agreement provides for a back-up satellite if difficulties arise with our
designated satellite, if we are required to change the designated satellite we
would be required to readjust our equipment. This adjustment could take
several weeks and would result in a decrease in the quality of our service and
an increase in our cost relating to the more expensive transmission costs of
distributing content from our hosting centers over our land-line network. The
ongoing failure of the satellite service we use could prevent us from
broadcasting content directly to the edge of the Internet. This would
significantly increase our costs and reduce our ability to cost-effectively
broadcast high-fidelity streaming video and audio content.

   Since we commenced offering our services in October 1999 we have
experienced two network outages. One was caused by a failure of one of our
servers and the other was caused by a failure in the land-line communication
services provided to us by a third party. Outages that have occurred to date
have resulted in between one and five hours of network downtime during which
time we were prevented from delivering our services to our customers. These
downtimes resulted in lost revenues for usage not billed during down periods.

   We may have inaccurately predicted our satellite capacity needs and may
find it difficult to add capacity when needed on reasonable terms.

   We may need to add additional satellite capacity as we take on additional
content provider customers that distribute their content over our network.
Increases in the amount of content that is broadcast through our network
decreases our remaining satellite capacity. We are currently using only a
small fraction of our contracted for capacity. Nevertheless, we cannot assure
you that we have contracted for sufficient satellite capacity under our
current three-year satellite capacity contract, that we will be able to renew
this contract or that we would be able to increase satellite capacity through
our current or a potential additional provider. Additional capacity may not be
available to us on reasonable terms or at all. Failure to obtain necessary
capacity would limit revenue growth.

   The market for Internet broadcasting services is new and our business will
suffer if it does not develop as we expect.

   The market for Internet broadcasting services is new and rapidly evolving.
Content providers, such as existing web-based companies and traditional media
and entertainment companies, may not increasingly seek to broadcast streaming
video and audio over the Internet. Therefore, we cannot be certain that a
viable market for our services will emerge or be sustainable. If this market
does not develop, or develops more slowly than we expect, our revenues will
suffer and we may not become profitable.

                                      10

   The markets in which we operate are highly competitive and we may be unable
to compete successfully against new entrants and established companies with
greater resources.

   We compete in a market that is new, intensely competitive, highly
fragmented and rapidly changing. We have experienced and expect to continue to
experience increased competition. Many of our current competitors, as well as
a number of our potential competitors, have longer operating histories,
greater name recognition and substantially greater financial, technical and
marketing resources than we do. Some of our current and potential competitors
have the financial resources to withstand substantial price competition.
Moreover, many of our competitors have more extensive customer bases, broader
customer relationships and broader industry alliances that they could use to
their advantage in competitive situations, including relationships with many
of our current and potential customers. We do not have exclusive contracts
with Internet service providers for the deployment of our servers within their
networks and we expect that many Internet service providers will allow our
competitors to install equipment at their sites. In addition, our competitors
may be able to respond more quickly than we can to new or emerging
technologies and changes in customer requirements.

   Some of our current or potential competitors may bundle their services with
other software or hardware to offer a full range of Internet broadcasting
products and services to meet all of the content distribution needs of content
providers. We currently do not offer a full range of products and services.
This may discourage content providers from purchasing services we offer or
Internet service providers from installing our servers in their facilities.

   As competition in the Internet broadcasting market continues to intensify,
new solutions will come to market. We are aware of other companies that are
focusing or may in the future focus significant resources on developing and
marketing products and services that will compete with ours. We believe our
competitors primarily come from five market segments:

  .  Internet content distribution networks which accelerate delivery of web
     pages, such as Akamai, Enron Communications and Digital Island;

  .  Internet webcasting companies that deliver streaming media through land-
     line networks, such as InterVu which was acquired by Akamai;

  .  Internet software vendors that reduce the cost of content distribution
     by storing content near the end user, such as Inktomi;

  .  Internet production and event services companies, such as Broadcast.com
     and Network24 Communications which was acquired by Akamai; and

  .  Satellite companies that deliver streaming video through satellite
     networks, such as PanAmSat and Cidera.

   Increased competition could result in:

  .  Price and revenue reductions and lower profit margins;

  .  Increased cost of service from telecommunications providers and revenue
     sharing demands by ISPs;

  .  Loss of customers; and

  .  Loss of market share.

   Any one of these results would harm our financial results.

   We believe that the Internet broadcasting and content delivery industry is
likely to encounter consolidation, such as the recent acquisition of InterVu
by Akamai, both of which compete with us. This consolidation could lead to the
formation of more formidable competitors and could result in increased
pressure on us to decrease our prices. In addition, consolidation among
Internet content providers could reduce the number of potential customers for
our services and may increase the bargaining power of these organizations,
which could force us to lower prices.

                                      11
<PAGE>

   Because our Internet content provider customers may terminate the use of
our services at any time without penalty, revenues from these customers may
decrease significantly without notice.

   We do not have exclusive contracts with our Internet content provider
customers. These customers may refrain from using our services or shift to use
the services of our competitors at any time without penalty. There is a risk
that some content providers will determine that it is more cost effective for
them to develop and deploy their own Internet broadcasting or content delivery
systems than it is to outsource these services to companies such as iBEAM.
This competitive threat is particularly acute from content providers that own
content distribution networks. If any of our existing or future content
provider customers make this determination and refrain from using our
services, our revenues will be harmed. A vertically integrated competitor is
more likely to use their internal resources rather than outsourcing these
services to us.

   If our commercial relationship with Microsoft terminates, then our business
could be harmed.

   We entered into an agreement with Microsoft Corporation in September 1999.
Our agreement with Microsoft provides that Microsoft will recommend us as a
service provider for the delivery of broadband streaming media over the
Internet. Considering the widespread acceptance of Microsoft's Windows
technology, we believe Microsoft's recommendation in this regard will be an
important source of customers for us. This agreement may be terminated by
either Microsoft or us if the other party materially breaches the agreement. A
termination of, or significant adverse change in, our relationship with
Microsoft could harm our ability to obtain customers and develop new
technologies that complement our existing service offerings.

   We have agreed to provide an aggregate of $200,000 of free services to
Internet content providers chosen by Microsoft.

   We have entered into an agreement with Microsoft to provide content
providers chosen by Microsoft with six months of free service provided that
the value of the services to all these participants does not in the aggregate
exceed $200,000. We cannot currently quantify the number of content providers
to whom we expect to provide free services under this arrangement. Microsoft
has not yet requested that we provide these free services. If they do so, our
revenues would be harmed.

   Our business will suffer if our network is not able to serve an increasing
number of users as demand increases.

   To date, we have deployed a limited number of our edge servers. As of March
31, 2000, we estimate that our network was sufficient to support up to 300,000
simultaneous end users. We estimate that as of that date less than 5% of
traffic delivered through our network was served by our edge servers. We
expect that we will be able to serve up to 40% of the traffic on our network
from the edge of the Internet by the end of 2000 due to our agreements with
ISPs, particularly America Online. However, we cannot be certain that our
network can connect and manage a substantially larger number of end users at
high transmission speeds while maintaining desired performance. In addition,
for a portion of our network, as usage of high-speed Internet access by end
users increases, we will need to make additional investments in our
infrastructure to maintain adequate transmission speed for delivery of content
to the end user. We cannot assure you that we will be able to make these
investments successfully or at a reasonable cost. Upgrading our infrastructure
may cause delays or failures in our network. As a result, in the future our
network may be unable to achieve or maintain a sufficiently high transmission
capacity. Our failure to achieve or maintain high capacity data transmission
could significantly reduce demand for our service, which would reduce our
revenue and cause our business and financial results to suffer.

   If more simultaneous users tried to access content off our network than we
have capacity for on the edge, the users representing excess capacity would be
served by our regional or master hosting centers. Supporting end users from
our regional and master hosting centers results in greater cost of services
than serving from the edge of our network but should not reduce the revenue
that we would otherwise generate.

                                      12

   Our business will suffer if we do not respond rapidly to technological
changes or if new technological developments make our services non-competitive
or obsolete.

   The market for Internet broadcasting services is characterized by rapid
technological change, frequent new product and service introductions and
changes in customer requirements. We may be unable to respond quickly or
effectively to these developments. If competitors introduce products, services
or technologies that are better than ours or that gain greater market
acceptance, or if new industry standards emerge, our services may become non-
competitive or obsolete, which would harm our revenues and cause our business
and financial results to suffer. In addition, technological developments could
eventually make Internet infrastructure much faster and more reliable such
that performance enhancing services like those we provide would be less
relevant to content providers.

   In developing our service, we have made, and will continue to make,
assumptions about the standards that our customers and competitors may adopt.
If the standards adopted are different from those which we may now or in the
future promote or support, market acceptance of our service may be
significantly reduced or delayed and our business will be seriously harmed. In
addition, the emergence of new industry standards could render our existing
services non-competitive or obsolete.

   We had operating losses of $30.2 million for the year ended December 31,
1999 and $21.7 million for the three months ended March 31, 2000 and our
accumulated deficit was $66.3 million as of March 31, 2000. Considering that
operating expenses are expected to increase in future periods we will need to
increase our revenues significantly to achieve profitability.

   We have never been profitable. We have incurred significant losses since
inception, including operating losses of $30.2 million for the year ended
December 31, 1999 and $21.7 million for the three months ended March 31, 2000.
Our operating losses as a percentage of revenue was 20,247% in 1999 and 4,074%
in the first quarter of 2000. As of March 31, 2000, we had an accumulated
deficit of $66.3 million. In fiscal 2000, based on the planned deployment of
our network, we expect to have capital expenditures of at least $40.0 million,
of which approximately $26.0 million was incurred in the first quarter. We
expect to continue to incur increasing operating losses in the future. We will
apply the proceeds from this offering to pay for our capital expenditures and
to fund these losses.

   We cannot be certain that our revenue will grow or that we will achieve
sufficient revenue to achieve profitability. Our failure to significantly
increase our revenue would seriously harm our business and operating results.
We have large fixed expenses, and we expect to continue to incur significant
and increasing sales and marketing, product development, administrative and
other expenses, including fees to obtain access to bandwidth transport of data
over our network, while we build out our network to the edge of the Internet.
As a result, we will need to generate significantly higher revenues to achieve
and maintain profitability. If our revenue grows more slowly than we
anticipate or if our operating expenses increase more than we expect or cannot
be reduced in the event of lower revenue, we may not become profitable.

   The uncertainty in the sales and installation cycles for our service
resulting from our limited operating history may cause revenue and operating
results to vary significantly and unexpectedly from quarter to quarter, which
could adversely affect our stock price.

   Because of our limited operating history and the nature of our business, we
cannot predict our sales and installation cycles. The uncertain sales and
installation cycles may cause our revenue and results of operations to vary
significantly and unexpectedly from quarter to quarter. If this occurs and our
quarterly operating results fall below the expectations of our investors or
securities analysts, if any are covering our common stock, then the market
price of our common stock could decline.

                                      13
<PAGE>

   We expect the rates we can charge for our services to decline over time,
which could reduce our revenue and could cause our business and financial
results to suffer.

   We expect the prices we can charge for our Internet broadcasting services
will decline over time as a result of, among other things, the increasing
availability of bandwidth at reduced costs and existing and new competition in
the markets we address. If we fail to accurately predict the decline in costs
of bandwidth or, in any event, if we are unable to sell our service at
acceptable prices relative to our costs, or if we fail to offer additional
services from which we can derive additional revenue, our revenue will
decrease and our business and financial results will suffer.

   We are currently pricing our services at levels that exceed our direct
variable costs but are insufficient to cover indirect costs such as our
network operations center and billing system. There is no assurance that our
revenues will increase to cover our increasing indirect costs, or that we have
accurately estimated indirect costs. If we fail to increase revenues, we may
not be able to achieve or maintain profitability.

   Our business will suffer if we do not anticipate and meet specific customer
requirements.

   Our current and prospective customers may require features and capabilities
that our current service offering does not have. To achieve market acceptance
for our service, we must effectively and timely anticipate and adapt to
customer requirements and offer services that meet these customer demands. The
development of new or enhanced services is a complex and uncertain process
that requires the accurate anticipation of technological and market trends. We
may experience design, manufacturing, marketing and other difficulties that
could delay or prevent the development, introduction or marketing of these new
or enhanced services. In addition, the introduction of new or enhanced
services also requires that we manage the transition from older services to
minimize disruption in customer service and ensure that we can deliver
services to meet anticipated customer demand. Our failure to offer services
that satisfy customer requirements would decrease demand for our products and
seriously harm our revenues and financial results.

   Our business will suffer if we do not expand our direct and indirect sales
organizations and our customer service and support operations.

   We currently have limited sales and marketing experience and limited
trained sales personnel. Our limited experience may restrict our success in
commercializing our services. Our services require a sophisticated sales
effort targeted at a limited number of key people within our prospective
customers' organizations. This sales effort requires the efforts of trained
sales personnel. We need to expand our marketing and sales organization in
order to increase market awareness of our service and generate increased
revenue. We are in the process of building our direct sales force and plan to
hire additional qualified sales personnel. Competition for these individuals
is intense, and we might not be able to hire the kind and number of sales
personnel we need. In addition, we believe that our future success is
dependent upon our ability to establish successful relationships for indirect
sales with a variety of distribution partners. If we are unable to expand our
direct and indirect sales operations, we may not be able to increase market
awareness or sales of our service, which may prevent us from increasing our
revenue and achieving and maintaining profitability.

   Hiring customer service and support personnel is very competitive in our
industry because there is a limited number of people available with the
necessary technical skills and understanding of our market. Once we hire these
personnel, they require extensive training. If we are unable to expand our
customer service and support organization or train these personnel as rapidly
as necessary, we may not be able to maintain satisfied existing customers of
our service, which would harm our revenues and our ability to achieve or
maintain profitability.

   We will incur significant costs relating to the planned expansion of our
marketing, sales and customer support organization. We are unable to quantify
the expenses associated with expanding our sales organization and customer
service and support operations because these expenses depend on a number of
factors relating to our operations, including the rate of hiring personnel and
the timing and amount of marketing and advertising

                                      14
<PAGE>

expenses. We expect that over the next two years these costs will
significantly exceed any revenues that we receive for our services. We expect
to apply the proceeds from this offering to the payment of these expenses. If
our revenues do not grow in the future, these costs may never be recuperated
and we may not become profitable.

   We face a number of risks related to our acquisition of webcasts.com, and
we may face similar risks in the future if we acquire other businesses or
technologies.

   In April 2000, we acquired webcasts.com. If we are unable to effectively
integrate webcasts.com's products, personnel and systems, our business and
operating results are likely to suffer. This integration will be made more
difficult because webcasts.com operations are located in Oklahoma City,
Oklahoma, where we currently have no operations. We are just beginning to
integrate webcasts.com with our operations. We expect this integration to
place a significant burden on our management team by diverting management's
attention from the day-to-day operations of iBEAM.

   As part of our business strategy, we frequently review acquisition and
strategic investment prospects that would complement our current service
offerings, augment our market coverage or enhance our technical capabilities,
or that may otherwise offer growth opportunities. If we make any future
acquisitions, we could:

  .  Issue equity securities, which would dilute current stockholders'
     percentage ownership;

  .  Incur substantial debt, the holders of which would have claims to our
     assets in preference to the holders of our common stock; or

  .  Assume contingent liabilities, which could materialize and involve
     significant cost.

   These actions could materially and adversely affect our operating results
and/or the price of our common stock. Acquisitions and investments may require
us to incur significant amortization and depreciation charges and acquisition
related costs that adversely affect our financial results. Acquisitions and
investment activities also entail numerous risks, including:

  .  Difficulties in the assimilation of acquired operations, technologies or
     services;

  .  Unanticipated costs associated with the acquisition or investment
     transaction;

  .  Adverse effects on existing business relationships with suppliers and
     customers;

  .  Risks associated with entering markets in which we have no or limited
     prior experience; and

  .  Potential loss of key employees of acquired organizations.

   We may not be able to successfully integrate webcasts.com or any business,
products, technologies or personnel that we might acquire in the future, and
our failure to do so could harm our business.

   We continue to look for acquisitions and investments. Although we do not
have any other commitments or agreements regarding any material acquisitions
or investments, we may use a portion of the net proceeds of this offering for
future acquisitions or investments.

   As a result of the webcasts.com acquisition, we will record $92.8 million
of goodwill and acquired intangibles, the amortization of which will increase
our net loss.

   As a result of the webcasts.com acquisition we will record $92.8 million of
goodwill and acquired intangibles which will be amortized over a three year
period. This will increase our net loss by approximately $20.6 million in
2000, $30.9 million in 2001 and 2002 and $10.4 million in 2003. To the extent
we do not generate sufficient cash flow to recover the amount of the
investment recorded, the investment could be considered impaired and could be
subject to earlier write-off. In such event, our net loss in any given period
could be greater than anticipated and the market price of our stock could
decline.

                                      15
<PAGE>

   We will require additional capital in the future and may not be able to
secure adequate funds on terms acceptable to us.

   The expansion and development of our business will require significant
capital, which we may be unable to obtain, to fund our capital expenditures
and operating expenses, including working capital needs. In fiscal 2000 we
expect to make $40.0 million in capital expenditures, of which $26.0 million
was incurred in the first quarter, including investments in edge servers,
hosting centers and our network operations center, and we expect to incur
significant and increasing losses.

   During the next 12 months, we expect to meet our cash requirements with
existing cash, cash equivalents and short-term investments, the net proceeds
from this offering and cash flow from sales of our services. The proceeds of
this offering are necessary in order to build out our network as planned. In
the absence of a public offering, to continue to execute on our current
business plan, we would attempt to raise capital in the private equity market.
To the extent such capital is not available, or until available, we would
exercise control of our discretionary expenses such as by reducing network
costs, capital expenditures and other discretionary expenses.

   We may fail to generate sufficient cash flow from the sales of our services
to meet our cash requirements. Further, our capital requirements may vary
materially from those currently planned if, for example, our revenues do not
reach expected levels or we have to incur unforseen capital expenditures and
make investments to maintain our competitive position. If this is the case, we
may require additional financing sooner than anticipated or we may have to
delay or abandon some or all of our development and expansion plans or
otherwise forego market opportunities. If we seek to raise additional capital
through the issuance of equity or equity-related securities, the percentage
ownership of existing stockholders will be diluted.

   After mid-2001 and possibly sooner we will need to raise additional
capital. We may not be able to obtain future equity or debt financing on
favorable terms, if at all. Future borrowing instruments such as credit
facilities and lease agreements are likely to contain restrictive covenants
and may require us to pledge assets as security for borrowings thereunder. Our
inability to obtain additional capital on satisfactory terms may delay or
prevent the expansion of our business.

   We may decide to raise additional equity capital in the next 12 months
through a follow-on public offering. The decision to do a follow-on public
offering will depend on market conditions, including whether our stock price
has increased and whether there is additional demand for our stock, and our
need for additional funds at the time.

   Our business will suffer if we fail to manage the expansion of our
operations properly.

   We have grown rapidly by hiring new employees and by expanding our offering
of services. Our total number of employees grew from 40 on March 4, 1999 to
266 on March 31, 2000 and several members of our senior management team have
only recently joined us. The acquisition of webcasts.com will add
approximately 95 employees. This growth has placed, and our growth in future
operations, if any, will continue to place, a significant strain on our
management systems and resources. Our ability to offer our services and
implement our business plan in a rapidly evolving market requires an effective
planning and management process. If we fail to:

  .  Improve our financial and managerial controls, reporting systems and
     procedures,

  .  Hire, train, manage and retain additional qualified personnel, including
     additional senior management level personnel to fulfill our current or
     future needs,

  .  Integrate the operations of webcasts.com, and

  .  Effectively manage and multiply relationships with our customers,
     suppliers, and other third parties,

we may be unable to execute our business plan, which would curtail our growth
and harm our results of operations.

   In addition, we have recently hired and plan to hire in the near future a
number of key employees and officers. To become integrated into our company,
these individuals must spend a significant amount of time learning our

                                      16
<PAGE>

business model and management system, in addition to performing their regular
duties. Accordingly, the integration of new personnel has resulted and will
continue to result in some disruption to our ongoing operations. If we fail to
integrate new employees in an efficient manner, our business and financial
results will suffer.

   The unpredictability of our quarterly results may adversely affect the
trading price of our common stock.

   Our revenue and operating results will vary significantly from quarter to
quarter due to a number of factors, many of which are outside of our control
and any of which may cause our stock price to fluctuate. The primary factors
that may affect our quarterly results include the following:

  .  Fluctuations in the demand for our Internet broadcasting services;

  .  The timing and size of sales of our services;

  .  The timing of recognizing revenue and deferred revenue;

  .  New product and service introductions and enhancements by our
     competitors and ourselves;

  .  Changes in our pricing policies or the pricing policies of our
     competitors;

  .  Increases in the prices of, and availability of, the products, services
     or components we purchase, including bandwidth;

  .  Our ability to attain and maintain quality levels for our services;

  .  Expenses related to testing our services;

  .  Costs related to acquisitions of technology or businesses; and

  .  General economic conditions as well as those specific to the Internet
     and related industries.

   We plan to increase significantly our operating expenses to fund the build-
out of our broadcast network, accelerate engineering and development, expand
our sales and marketing operations, broaden our customer support capabilities
and continue to develop new distribution channels. We also plan to expand our
general and administrative functions to address the increased reporting and
other administrative demands which will result from this offering and the
increasing size of our business. Our operating expenses are largely based on
anticipated revenue trends and a high percentage of our expenses are, and will
continue to be, fixed in the short term. As a result, a delay in generating or
recognizing revenue for the reasons set forth above, or for any other reason,
could cause significant variations in our operating results from quarter to
quarter and could result in substantially operating losses.

   Due to the above factors, we believe that quarter-to-quarter comparisons of
our operating results are not a good indication of our future performance. It
is likely that in some future quarters our operating results may be below the
expectations of investors and security analysts, if any follow our stock. In
this event, the price of our common stock will probably fall.

   Our On-Stage service currently represents a substantial portion of our
revenues and if we are unsuccessful in commercially selling our On-Air and On-
Demand services, our revenues will not grow significantly.

   We currently offer three primary services: iBEAM On-Stage, iBEAM On-Air and
iBEAM On-Demand. Sales of our On-Stage service accounted for 74% of our
revenue in 1999. Sales of our On-Air services accounted for 6% of our revenue
in 1999. Sales of our On-Demand services accounted for 3% of our revenue in
1999. We expect that sales of our On-Stage services will decline as a
percentage of total revenue in the future. However, we substantially depend on
this service for our near-term revenue. Any decline in the price of, or demand
for, our On-Stage service, or its failure to achieve broad market acceptance,
would seriously harm our business. In addition, we believe that our future
growth and a significant portion of our future revenue will depend on the

                                      17
<PAGE>

commercial success of our On-Air and On-Demand services. If our customers do
not widely adopt, purchase and successfully deploy our services, our revenues
will not grow significantly and our business will be seriously harmed.

   We rely on a limited number of customers, and any decrease in revenues
from, or loss of, these customers, without a corresponding increase in
revenues from other customers, would harm our operating results.

   Our customer base is limited and highly concentrated. We began recognizing
revenues from sales of our products in the quarter ended December 31, 1999.
Three customers accounted for an aggregate of 68% of our revenue in the
quarter ended December 31, 1999: ProWebCast accounted for 40%, MusicNow, Inc.
accounted for 15% and Pixelworld accounted for 13% of our revenue. In the
three months ended March 31, 2000 NetRadio.com accounted for 12% of revenues.
We expect that the majority of our revenues will continue to depend on sales
of our products to a small number of customers. If current customers do not
continue to place significant orders, we may not be able to replace these
orders. In addition, any downturn in the business of existing customers could
result in significantly decreased sales to these customers, which could
seriously harm our revenues and results of operations. Sales to any single
customer may vary significantly from quarter to quarter.

   America Online accounted for an aggregate of 20% of webcasts.com's revenue
in 1999. The loss of this customer or a significant reduction in the level of
webcasts.com's services used by this customer, could seriously harm our
results of operations.

   We expect to amortize stock-based compensation expense of $12.2 million in
the remainder of 2000, $9.3 million in 2001, $4.8 million in 2002, and $2.1
million in 2003, which will decrease our net earnings during these periods.

   In connection with the grant of stock options to employees and consultants
for the period from March 20, 1998 (inception) to March 31, 2000, we recorded
unearned stock-based compensation of $37.9 million, of which $5.4 million was
amortized during 1999 and $4.1 million was amortized in the first quarter of
2000. If our stock price increases, the amount of stock-based compensation
related to stock option grants to consultants would increase as the fair value
of these grants is re-measured at each reporting date using a Black-Scholes
option pricing model. These expenses will increase our losses during each of
these periods and delay our ability to achieve profitability.

   We depend on our executive officers to manage our business effectively in a
rapidly changing market and, if we are unable to retain our executive
officers, our ability to compete could be harmed.

   Our future success depends upon the continued services of our executive
officers who have critical industry experience and relationships that we rely
on in implementing our business plan. We do not have "key person" life
insurance covering any of our executive officers. The loss of services of any
of our executive officers could delay the development and introduction of and
negatively impact our ability to sell our services.

   We face risks associated with international operations that could harm our
business.

   To be successful, we believe we must expand our international operations.
Therefore, we expect to commit significant resources to expand our
international sales and marketing activities. We are currently targeting the
United Kingdom, Germany, France, Hong Kong, Singapore, Indonesia, Malaysia and
India for expansion. The expenses we will incur in expanding our international
operations will depend on the arrangements into which we will enter to provide
our services in such markets. These factors have yet to be determined. We
recently entered into a letter of intent with Pacific Century CyberWorks to
establish a joint venture to introduce our services to the Pacific Rim, the
Indian subcontinent and the Middle East. In order to bring our services to
these regions, the joint venture will need to deploy a network of servers
which will involve large capital expenditures and operating expenses. While
the details of the joint venture have yet to be determined, we expect to incur
approximately

                                      18
<PAGE>


49% or less, depending on our percentage ownership, of the operating losses of
the joint venture. We expect the joint venture to begin delivering content to
end users by the end of 2000. In connection with the formation of the joint
venture, we expect to contribute $5.0 million to iBEAM Asia. We expect that
iBEAM Asia will be funded thereafter from independent third party sources. We
may decide to provide additional financing to iBEAM Asia in the future if
iBEAM Asia is unable to raise additional funding from third parties on
favorable terms. In addition, in connection with our expansion into Asia,
Europe, Latin America, Africa and the Middle East pursuant to our agreement
with InterPacket, we will incur capital expenditures in connection with our
deployment of servers in InterPacket's network. InterPacket's network serves
developing countries and there can be no assurance that these markets will
develop sufficiently to justify our investments. We are establishing a test
center for our systems in Hong Kong. We currently plan to begin placing
servers in up to 20 locations in InterPacket's network in the second half of
2000. We expect that our capital expenditures in 2000 in connection with
deployment in InterPacket's network will be less than $1.0 million.

   We may be unable to maintain or increase market demand for our service
internationally, which may harm our business. As we expand internationally, we
will be increasingly subject to a number of risks associated with
international business activities that could increase our costs, lengthen our
sales cycle and require significant management attention. These risks include:

  .  Potential difficulty in enforcing intellectual property rights in
     foreign countries;

  .  Compliance with and unexpected changes in regulatory requirements
     resulting in unanticipated costs and delays;

  .  Lack of availability of trained personnel in international locations;

  .  Tariffs, export controls and other trade barriers;

  .  Longer accounts receivable payment cycles than in the United States;

  .  Potential difficulty in obtaining access to additional satellite and
     telecommunication transmission capacity;

  .  Potential difficulty of enforcing agreements and collecting receivables
     in some foreign legal systems;

  .  Potentially adverse tax consequences, including restrictions on the
     repatriation and earnings;

  .  General economic conditions in international markets; and

  .  Currency exchange rate fluctuations.

Risks Related to Legal Uncertainty

   Any inability to adequately protect our intellectual property could harm
our competitive position.

   We rely on a combination of patent, copyright, trademark and trade secret
laws and restrictions on disclosure to protect our intellectual property
rights. Our future growth, if any, will depend on our ability to continue to
seek patents and otherwise protect the intellectual property rights in our
network technology. However, these legal protections afford only limited
protection; competitors may gain access to our network technology, including
our software and server technology, which may result in the loss of our
customers. Other companies, including our competitors, may obtain patents or
other proprietary rights that would prevent, limit or interfere with our
ability to make, use or sell our service. This would cause our revenues to
decline and seriously harm our results of operations.

   We may in the future initiate claims or litigation against third parties
for infringement of our proprietary rights or to determine the scope and
validity of our proprietary rights or the proprietary rights of competitors.
These claims could result in costly litigation and the diversion of our
technical and management personnel. As a result, our operating results could
suffer and our financial condition could be harmed.

                                      19
<PAGE>

   We could incur substantial costs defending our intellectual property from
infringement or a claim of infringement.

   Any litigation or claims, whether or not valid, could result in substantial
costs and diversion of resources. Companies in the Internet industry are
increasingly bringing suits alleging infringement of their proprietary rights,
particularly patent rights. Our patent applications to date cover our
streaming platform standard, content management, distribution capabilities and
subscriber management. If a company brings a claim against us, we may be found
to infringe their proprietary rights. In the event of a successful claim of
infringement against us and our failure or inability to license the infringed
technology, our business and operating results would be significantly harmed.

   In January 2000, we received a letter from a competitor, which suggested
that we review patents to which this competitor claims rights. These patents
purport to cover "a system and method for delivery of video and data over a
computer network." We believe that we do not infringe any claims of these
patents. However, there can be no assurance that this competitor will agree
with our conclusion or not pursue a claim or litigation against us. To date,
no complaint has been filed or served.

   Intellectual property litigation or claims could force us to do one or more
of the following:

  .  Cease selling, incorporating or using products or services that
     incorporate the challenged intellectual property;

  .  Obtain a license from the holder of the infringed intellectual property
     right, which license may not be available on reasonable terms if at all;
     and

  .  Redesign products or services that incorporate the disputed technology.

   If we are forced to take any of the foregoing actions, we could face
substantial costs and our business may be seriously harmed. Although we carry
general liability insurance, our insurance may not cover potential claims of
this type or be adequate to indemnify us for all liability that may be
imposed.

   Internet-related laws could cause us to change the manner in which we
operate our network, which could be disruptive, time consuming and expensive.

   Our Internet broadcast network is designed to deliver streaming media to
large audiences of simultaneous users. Currently our network and the media we
broadcast is largely unregulated, even though traditional television and radio
are highly regulated by the Federal Communications Commission. If laws and
regulations that apply to communications over the Internet are enacted that
require us to change the manner in which we operate our network, our business
could be disrupted with time consuming and expensive modifications of our
technology. In addition, our business could be harmed to the extent that our
content provider customers are adversely affected. Laws and regulations that
apply to communications over the Internet are becoming more prevalent. Several
bills are currently being considered by the U.S. Congress. Recently the U.S.
Congress enacted Internet laws regarding children's privacy, copyrights,
taxation and the transmission of sexually explicit material. The European
Union recently enacted its own privacy regulations, and is currently
considering copyright legislation that may extend the right of reproduction
held by copyright holders to include the right to make temporary copies for
any reason. The adoption or modification of laws or regulations relating to
the Internet, or interpretations of existing law, could harm our business
directly or indirectly due to effects on our customers.

Risks Related To The Securities Markets And This Offering

   Our stock price may be volatile which could result in litigation against us
and substantial losses for investors purchasing shares in this offering.

   Prior to this offering, you could not buy or sell our common stock
publicly. An active public market for our common stock may not develop or be
sustained after this offering. The market for technology stocks has been

                                      20
<PAGE>

extremely volatile. The following factors could cause the market price of our
common stock in the public market to fluctuate significantly from the price
paid by investors in this offering:

  .  Announcements by us or our competitors of significant contracts, new
     products or services offerings or enhancements, acquisitions,
     distribution partnerships, joint ventures or capital commitments;

  .  Variations in our quarter-to-quarter operating results including our
     failure to meet estimates of financial analysts;

  .  Changes in financial estimates by securities analysts, if any analysts
     elect to follow our stock;

  .  Our sales of common stock or other securities in the future or
     substantial sales by current stockholders after the 180-day lock-up
     expires;

  .  Changes in market valuations of networking, Internet and
     telecommunications companies;

  .  The addition or departure of our personnel; and

  .  Fluctuations in stock market prices and volumes.

   Volatility in the market price of our common stock may prevent investors
from being able to sell their common stock at or above our initial public
offering price.

   In the past, class action litigation has often been brought against
companies following periods of volatility in the market price of those
companies' common stock. We may become involved in this type of litigation in
the future. Litigation is often expensive and diverts management's attention
and resources, which could materially and adversely affect our business and
results of operations.

   Insiders will beneficially own approximately 37.5% of our outstanding
common stock after this offering and could limit investors' ability to
influence the outcome of key transactions, including changes of control.

   We anticipate that our executive officers and directors, together with
Accel Partners and Crosspoint Venture Partners, each of which is an entity
affiliated with one of our directors, will in the aggregate, own approximately
37.5% of our outstanding common stock following the completion of this
offering. These stockholders, if acting together, would be able to influence
significantly all matters requiring approval by our stockholders, including
the election of directors and the approval of mergers or other business
combination transactions.

   Provisions of our charter documents and agreements with some of our large
stockholders may have anti-takeover effects that could prevent a change in
control even if the change in control would be beneficial to our stockholders.

   Our board of directors will be divided into three classes, with each class
serving staggered three-year terms. This may discourage a third party from
making a tender offer or otherwise attempting to obtain control of us because
it generally makes it more difficult for stockholders to replace a majority of
the directors. We have in place procedures which prevent stockholders from
acting without holding a meeting and which limit the ease with which a
stockholder meeting can be called. We are subject to the "interested
stockholder" provisions of Delaware law which impose restrictions on mergers
and other business combinations between us and any holder of 15% or more of
our outstanding common stock. These provisions of our amended and restated
certificate of incorporation, by-laws, 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, each of Microsoft, Sony, Pacific Century CyberWorks, America
Online, Covad and Liberty Media, which in the aggregate will own 15.9% of our
common stock upon the closing of this offering, have agreed to vote their
securities as directed by our board of directors in any merger in which more
than 50% of our voting power is transferred or in a sale of substantially all
of our assets. This obligation lapses for each of these companies if and when
it owns less than 5% of our voting power. Microsoft, Sony, Pacific Century
CyberWorks, America Online, Excite@Home and Covad have each also agreed not to
acquire more than 15.0% of our voting stock at any time before the end of
April 2005 without our permission. Our agreement with these stockholders could
make it more difficult for a third party or one of these entities to acquire
us, even if doing so would be beneficial to our stockholders.

                                      21
<PAGE>

   The sale of a substantial number of shares of common stock could cause the
market price of our common stock to decline.

   After this offering, we will have a total of 106,147,834 shares of common
stock outstanding, or 107,797,834 shares if the underwriters exercise their
entire over-allotment option. The sale by us or the resale by stockholders of
shares of our common stock in the public market after the offering could cause
the market price of the common stock to decline. The federal securities laws
impose restrictions on the ability of substantially all stockholders to resell
their shares of common stock. In addition, we, our executive officers,
directors and certain other stockholders have agreed with Morgan Stanley & Co.
Incorporated, one of the representatives of the underwriters, not to sell
their shares for a period ending 180 days from the date of the prospectus for
the offering. Accordingly, the 106,147,834 shares of common stock outstanding
after this offering will be available for resale in the public market as
follows:

                                 for the offering
      13,275,896                 Various dates thereafter
</TABLE>

   In addition, 1,949,987 shares of our common stock issuable upon exercise of
warrants will become eligible for sale on various dates upon expiration or
release of the lock-up agreements.

   After this offering and expiration or release of the lock-up agreements,
holders of 76,260,334 shares of the common stock and the holders of warrants
to purchase approximately 1,438,687 shares of common stock may require us to
register their shares for resale under the federal securities laws.

   We intend to file a registration statement following this offering to
permit the sale of shares of common stock under our stock plans. As of March
31, 2000, options to purchase 11,816,815 shares of common stock with a
weighted average exercise price per share of $3.38 were outstanding,
substantially all of which are subject to agreements with Morgan Stanley & Co.
Incorporated not to sell such shares for 180 days from the date of the
prospectus for the offering. Registration of such shares would result in these
stockholders being able to immediately resell their shares in the public
market after expiration or release of the lock-up agreements. Any such sales
or anticipation thereof could cause the market price of the common stock to
decline.

   We have no agreement or understanding with Morgan Stanley & Co.
Incorporated for a waiver of these lock-up restrictions. However, Morgan
Stanley & Co. Incorporated may, in its discretion, release us or any of our
stockholders at any time, without notice, prior to the expiration of the lock-
up period. In some cases underwriters have agreed to waive lock-up
restrictions when a company's stock has performed well for a sustained period
of time, in order to allow a follow-on offering of common stock. Any decision
by Morgan Stanley & Co. Incorporated to waive the lock-up restrictions would
depend on a number of factors, including market conditions, the performance of
our common stock in the market and our financial condition at that time. If
Morgan Stanley & Co. Incorporated were to waive the lock-up restrictions prior
to the expiration of the lock-up period, and our stockholders were to sell
additional shares of common stock to the public, the market price of our
common stock could decline.

   You will experience immediate and significant dilution of book value per
share.

   The initial public offering price of our common stock will be substantially
higher than the net tangible book value per share of the outstanding common
stock immediately after this offering. Therefore, based upon an assumed
initial public offering price of $10.00 per share, if you purchase our common
stock in this offering, you will incur immediate dilution of $8.40 per share.
If additional shares are sold by the underwriters following exercise of their
over-allotment option there will be further dilution.

   In addition, as of March 31, 2000, we had outstanding options to purchase
11,816,815 shares of common stock at a weighted average exercise price of
$3.38 per share and, on an as converted basis, warrants to purchase 1,949,987
shares of common stock at a weighted average exercise price of $3.42 per
share. If these outstanding options or warrants are exercised there will be
further dilution.

                                USE OF PROCEEDS

   The net proceeds to us from the sale of 11,000,000 shares of common stock
in this offering at an assumed public offering price of $10.00 per share are
estimated to be approximately $100.6 million, or approximately $115.9 million
if the underwriters' over-allotment option is exercised in full, after
deducting estimated underwriting discounts and commissions and estimated
offering expenses payable by us.

   The principal purposes of this offering are to obtain additional working
capital, to establish a public market for our common stock, to increase our
visibility in the marketplace and to facilitate future access to public
capital markets.

   We expect to use the net proceeds for general corporate purposes, including
working capital and capital expenditures, and to fund operating losses. We
anticipate spending at least $15.0 million of the proceeds of this offering on
capital expenditures primarily for the purpose of expanding our network
operations. Our management will retain broad discretion in the allocation of
the remaining net proceeds of this offering. Although we may use a portion of
the proceeds to acquire other businesses, products or technologies that are
complementary to our business, we have no specific acquisitions planned.

   Pending such uses, we intend to invest the net proceeds of this offering in
short-term, investment-grade, interest-bearing securities.

                                DIVIDEND POLICY

   We have never paid cash dividends on our common stock. We currently intend
to retain all of our future earnings to finance the growth and development of
our business. We do not intend to pay cash dividends on our common stock in
the foreseeable future.

     shares into the same number of shares of common stock; and

  .  on a pro forma basis as adjusted for the sale by us of 11,000,000 shares
     of common stock in this offering and the receipt of the estimated net
     proceeds therefrom, after deducting the estimated underwriting discounts
     and commissions and estimated offering expenses.

                                   DILUTION

   Our pro forma net tangible book value as of March 31, 2000, was $69.4
million or $0.73 per share of common stock. Our pro forma net tangible book
value per share as of March 31, 2000 represents the amount of our total
tangible assets reduced by the amount of our total liabilities and divided by
the total number of shares of our common stock outstanding assuming (i) the
conversion of all outstanding shares of our redeemable convertible preferred
stock as of March 31, 2000 into 66,489,527 shares of common stock upon the
closing of this offering; (ii) the acquisition of webcasts.com as if it
occurred on March 31, 2000 and the conversion of the related issuance of
8,233,173 shares of series F redeemable convertible preferred stock into the
same number of shares of common stock; (iii) the issuance of 1,000,000 shares
of our series G redeemable convertible preferred stock to The Walt Disney
Company prior to the completion of the offering for $10.0 million at a price
equal to the per share price to the public in the offering and the conversion
of those shares into the same number of shares of common stock; and (iv) the
issuance of 537,634 shares of our series H redeemable convertible preferred
stock to Excite@Home prior to the completion of the offering for $5.0 million
at a price equal to the per share price to the public in the offering, less
estimated underwriting discounts and commissions, and the conversion of those
shares into the same number of shares of common stock. After giving effect to
the sale by us of the 11,000,000 shares of common stock offered hereby at an
assumed initial public offering price of $10.00 per share, after deduction of
estimated underwriting discounts and commissions and estimated offering
expenses, our pro forma as adjusted net tangible book value at March 31, 2000
would have been $169.9 million or $1.60 per share. This represents an
immediate increase in net tangible book value to existing stockholders of
$0.87 per share and an immediate dilution to new investors of $8.40 per share.
The following table illustrates the per share dilution:

   The table assumes no exercise of the underwriters over-allotment option and
no exercise of stock options or warrants outstanding at March 31, 2000. As of
March 31, 2000, there were options outstanding to purchase a total of
11,816,815 shares at a weighted average exercise price of $3.38 per share,
while 4,069,804 shares were reserved for future grants under our 1998 Stock
Plan. As of March 31, 2000, there were warrants outstanding to purchase
1,949,987 shares of common stock issuable upon exercise and conversion of
outstanding convertible preferred stock warrants at a weighted average
exercise price of $3.42 per share. We will assume all outstanding options
granted under webcasts.com's 1999 Stock Option Plan, which will convert into
options to purchase 706,285 shares of series F redeemable convertible
preferred stock at a weighted average exercise price of $3.54 per share. To
the extent there are exercises of any of these options, there will be further
dilution to new investors. There will be additional dilution if our
webcasts.com division meets revenue targets in the twelve month period
following the closing of the webcasts.com acquisition, which would require us
to issue up to 1,243,932 shares of common stock to the former webcasts.com
shareholders. See "Capitalization," "Management--Compensation of Directors"
and "--Executive Compensation."

                            SELECTED FINANCIAL DATA

   The following selected financial data should be read in conjunction with,
and are qualified by reference to, our audited financial statements and notes
and "Management's Discussion and Analysis of Financial Condition and Results
of Operations" appearing elsewhere in this prospectus. The statements of
operations data for the period from March 20, 1998 (Inception) to December 31,
1998 and for the year ended December 31, 1999, and the balance sheet data as
of December 31, 1998 and 1999 are derived from, and are qualified by reference
to, our audited financial statements.

   The unaudited pro forma statement of operations gives effect to the
webcasts.com acquisition as if it had occurred on January 1, 1999 and presents
the results of operations of iBEAM for the year ended December 31, 1999 and
for the three months ended March 31, 2000 combined with the unaudited pro
forma statement of operations of webcasts.com for the year ended December 31,
1999 and for the three months ended March 31, 2000, respectively. The
unaudited pro forma statement of operations of webcasts.com includes the
results of operations of webcasts.com for the year ended December 31, 1999
combined with the results of operations of The Rock Island Group, Inc., or
RIG, for the period from January 1, 1999 to October 14, 1999 as if the RIG
acquisition occurred on January 1, 1999. The unaudited pro forma combined
balance sheet gives effect to the acquisition of webcasts.com as if it
occurred on March 31, 2000 and combines the balance sheet of iBEAM as of
March 31, 2000 and the consolidated balance sheet of webcasts.com as of March
31, 2000. On October 15, 1999, webcasts.com completed its acquisition of all
the outstanding capital stock of RIG. The RIG acquisition was accounted for
using the purchase method of accounting and, accordingly, the net assets and
results of operations of RIG have been included in the consolidated financial
statements of webcasts.com since the acquisition date.

   The pro forma financial information should also be read in conjunction with
the historical financial statements and notes to webcasts.com, which are
included elsewhere in this prospectus, and "Management's Discussion and

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

   The following discussion of our financial condition and results of
operations should be read in conjunction with the financial statements and
notes included elsewhere in this prospectus. This prospectus contains forward-
looking statements that involve risks and uncertainties. Our actual results
could differ significantly from those discussed in these forward-looking
statements as a result of certain factors, including those set forth under
"Risk Factors" and elsewhere in this prospectus.

Overview

   We provide a global Internet broadcast network that delivers streaming
media to large audiences of simultaneous users with viewing and listening
quality that approaches that of television and radio. We offer our services to
content providers seeking to enhance the quality of their delivery and reach
larger audiences at lower costs. In order to offer our customers a broader set
of services, in April 2000 we acquired webcasts.com, Inc., a provider of
production consulting services and tools. Webcasts.com services assist content
providers with integrating streaming media and e-commerce functions such as
chat, e-commerce data base links and pay-per-view.

   iBEAM commenced operations in March 1998 and began offering streaming media
delivery service in October 1999. Since our inception, we have incurred
significant losses and as of March 31, 2000, we had an accumulated deficit of
$66.3 million. We have not achieved profitability on a quarterly basis, and
anticipate that we will continue to incur substantial and increasing net
losses. We expect to incur significant and increasing engineering and
development and sales, general and administrative expenses and, as a result,
we will need to generate significant revenues to achieve profitability.

Acquisition of webcasts.com

   We entered into a definitive merger agreement to acquire privately-held
webcasts.com, a provider of interactive broadcasting services and proprietary
Internet tools on March 21, 2000. We intend to account for the transaction as
a purchase business combination. The acquisition is intended to qualify as a
tax-free reorganization.

   On April 28, 2000 we consummated the transaction and issued 8,233,173
shares of our series F preferred stock to webcasts.com's security holders and
assumed webcasts.com's outstanding options which converted into 706,285 shares
of our series F preferred stock. We also issued a $3.0 million note to
webcasts.com's redeemable preferred shareholders. In addition, the former
security holders of webcasts.com may receive an additional 1,243,932 shares of
stock if our webcasts.com division meets certain revenue targets in the twelve
months after the closing of the acquisition. The purchase price was
approximately $92.2 million.

   As result of the acquisition, we expect to expect to incur merger-related
costs of up to $1.7 million and to record approximately $92.8 million of
intangible assets and goodwill on our balance sheet, which will result in
amortization expense of approximately $20.6 million in 2000, $30.9 million in
2001 and 2002 and $10.4 million in 2003. These charges will increase our
expenses and losses during each of these periods and delay our ability to
achieve profitability.

Revenue

   We derive our revenue from charging content providers for broadcasting
services that include On-Air, On-Stage and On-Demand distribution services. We
also derive revenue from other services, including targeted advertising,
production, event management, encoding and acquisition services. We expect
broadcasting services to provide the largest and fastest growing revenue
element of our services.

   Our broadcasting services are typically charged based on the volume of
content delivered to end-users as measured in megabytes or megabits consumed
and therefore varies with the number of viewers, the access speeds of the
viewers and time viewers spend viewing content broadcast by us. Currently, On-
Air and On-Demand services are typically priced based on actual usage, which
is measured by the volume of megabits transferred during the month, for which
we typically charge $.005 to $.01 per megabyte per month subject to a minimum

                                      29
<PAGE>


payment. In addition, for On-Demand customers, there is a monthly fee for
content stored on our network, which is measured in gigabytes. On-Stage
services can be priced under a fixed-fee arrangement or on actual usage in
terms of megabits transferred. To date, content providers have typically
elected to enter into fixed-fee arrangements in order to fix the price of a
broadcasting event. We price our fixed-fee arrangements using an estimate of
the amount of content delivered, which includes a forecast of the expected
number of viewers, the access speeds of the viewers and the duration of the
event. We typically charge $.005 to $.01 per megabyte transferred for our On-
Stage services. Other services such as production, event management, encoding
and acquisition services, are generally provided on a consulting basis on
either an hourly or fixed price billing.

   Cost of Services (Direct and Indirect)

   Cost of broadcasting Internet content includes both direct costs that vary
with the volume of content delivered and relatively fixed indirect costs, such
as staffing for a 24 hour network operations center. The cost of other
services, such as production, event management, encoding and acquisition
services, are primarily related to manpower costs for delivery of those
services.

   Direct broadcasting costs include depreciation of network servers,
satellite transmission charges and charges for using land-line networks. In
proportion, the largest direct cost is the cost of using land-line networks.
For ISPs to which we deliver content into their end-user distribution system
via satellite broadcast, that is the "edge" of the Internet, we avoid the
land-line costs. Therefore it is our goal to increase the amount of content we
deliver to the edge of the Internet from less than 5% of traffic delivered
through our network as of March 31, 2000 to 40% by the end of 2000. Because of
our broadcast economics, we deliver content to ISPs at no charge, thereby
relieving them of charges they ordinarily would be required to pay to receive
content. As of March 31, 2000, we have agreements with over 90 ISPs that will
allow us to deliver content through their networks to the edge of the
Internet. Although four of the ISPs to which we deliver content have
negotiated access fees, these fees have represented lower costs to iBEAM than
paying for land-lines. The fees we pay to these ISPs are based on a percentage
of the revenue we derive from content delivered through their network, ranging
from 15 to 20%. As of March 31, 2000, less than 2% of revenue was subject to
access fees. Because the ISPs that we pay fees to tend to be the ISPs with
larger networks, we believe that as we expand our network, we will pay fees
with respect to more than 50% of the Internet traffic delivered through our
network. In addition, we expect the aggregate number of ISPs that receive
access fees will increase.

   Indirect broadcasting costs are primarily the cost of equipment, operations
management software and personnel related to operating a 24 hour network
operations center. As such these costs are relatively fixed and independent of
volume of content delivered. We expect these indirect costs to be
approximately $23.0 million in fiscal 2000.

   Engineering and Development

   Engineering and development expenses consist primarily of salaries and
personnel costs related to the design, development and enhancement of our
service and the development of new applications that may be added to our
network. We believe that engineering and development is critical to our
strategic business development objectives and intend to enhance our technology
to meet the changing requirements of market demand. We expect our engineering
and development expenses to increase significantly in the future. The amount
that we will actually spend on engineering and development expenses is highly
uncertain and will depend on various factors that are difficult to predict
including the rate at which we believe it is in our business interests to
introduce new services and the availability for hire of qualified personnel.

   Sales and Marketing

   Sales and marketing expenses consist primarily of salaries, advertising,
promotions and related costs of sales and marketing personnel. We expect that
sales and marketing expenses will increase in the future as we hire additional
personnel, expand our operations domestically and internationally, initiate
additional marketing programs and establish sales offices in new locations.

                                      30
<PAGE>

   General and Administrative

   General and administrative expenses consist primarily of salaries and
related costs, operations and finance personnel, recruiting expenses,
professional fees and legal and accounting services. We expect that general
and administrative expenses will increase in the future as we hire additional
personnel, expand our operations domestically and internationally and incur
additional costs related to the growth of our operations as a public company.

   Amortization of Stock-based Compensation

   In connection with the grant of stock options to employees and consultants
since inception, we recorded unearned stock-based compensation of $37.9
million, representing the difference between the deemed fair value of our
common stock at the date of grant and the exercise price of such options. Such
an amount, net of amortization, is presented as a reduction of stockholders'
equity and amortized over the vesting period of the applicable option. Stock-
based compensation expense related to stock options granted to consultants is
recognized as the stock options are earned. At each reporting date, we re-
value the stock-based compensation using the Black-Scholes option pricing
model. As a result, the stock-based compensation expense will fluctuate as the
fair market value of our common stock fluctuates. We believe that the fair
value of the stock options are more reliably measurable than the fair value of
the services received due to the facts that we do not have records of time
spent by each consultant on matters related to iBEAM and that we do not have
the ability to ascertain what the fair market billing rates are for the
consultant's work. As of March 31, 2000, we expect to amortize unearned stock-
based compensation of $12.2 million in the remainder of 2000, $9.3 million in
2001, $4.8 million in 2002 and $2.1 million 2003.

   The following table summarizes operating costs and expenses, excluding the
non-cash amortization of stock-based compensation:

iBEAM's Results of Operations for the Three Months Ended March 31, 1999 and
2000

   Revenue. We recognized $532,000 of revenue in the first quarter of 2000. We
did not generate revenues in the first quarter of 1999. Fees for On-Stage, On-
Air and On-Demand services accounted for 25%, 27% and 36%, respectively, of
total revenue for the first quarter of 2000. As we continue to expand our
network and as more companies distribute content over our network, we expect
our revenue will increase in future periods. We also expect our On-Air and On-
Demand services will increase as a percentage of total revenue.

                                      31
<PAGE>


   Cost of Services (Direct and Indirect). Cost of services increased by $6.3
million, or 755%, from $0.8 million in the first quarter of 1999 to $7.1
million in the first quarter of 2000. This increase was primarily due to
network bandwidth, satellite transmission, co-location and content acquisition
expenses of $2.0 million, network server and software depreciation of $1.4
million and salaries, bonuses and related taxes of $1.1 million as we expanded
our network and added capacity in late 1999. Headcount included in cost of
services increased from 12 at March 31, 1999 to 56 at March 31, 2000.

   Engineering and Development. Engineering and development expenses increased
by $3.4 million, or 632%, from $0.5 million in the first quarter of 1999 to
$3.9 million in the first quarter of 2000. This increase was primarily due to
an increase in consultant expenses of $0.7 million and in salaries, bonuses
and related taxes of $1.5 million as additional engineers were hired
throughout 1999. Headcount included in engineering and development increased
from 16 at March 31, 1999 to 103 at March 31, 2000.

   Sales and Marketing. Sales and marketing expenses increased by $3.7
million, or 301%, from $1.2 million in the first quarter of 1999 to $4.9
million in the first quarter of 2000. This increase was primarily due to an
increase in salaries, commissions, bonuses and related taxes of $1.6 million,
travel and entertainment expenses of $0.4 million and advertising and
promotional expenses of $0.9 million as we expanded our sales and marketing
organization and promoted our network. Headcount included in sales and
marketing increased from 15 at March 31, 1999 to 78 at March 31, 2000.

   General and administrative. General and administrative expenses increased
by $1.6 million, or 246%, from $0.6 million in the first quarter of 1999 to
$2.2 million in the first quarter of 2000. This increase was primarily due to
an increase in salaries and related taxes of $0.6 million and professional
services of $0.2 million as we began to provide infrastructure to support our
growing operations. Headcount included in general and administrative increased
from ten at March 31, 1999 to 40 at March 31, 2000.

   Amortization of Stock-based Compensation. Amortization of employee stock-
based compensation increased by $3.9 million from $0.2 million in the first
quarter of 1999 to $4.1 million in the first quarter of 2000 primarily due to
the grant of stock options to newly hired employees and consultants. In
connection with the grant of stock options to consultants, we recorded stock-
based compensation expense of $12,000 in the first quarter of 1999 and $1.2
million in the first quarter of 2000.

   Other Income and Expense, Net. Other income and expense, net increased from
$30,000 in the first quarter of 1999 to $317,000 in the first quarter of 2000
primarily due to an increase in interest income based on larger cash balances.

   Net Loss. Net loss increased by $18.0 million, or 526%, from $3.4 million
in the first quarter of 1999 to $21.4 million in the first quarter of 2000.
The increase in the net loss is primarily attributable to increases in
operating costs and expenses of $18.8 million, including an increase in
amortization of stock-based compensation of $3.9 million.

Webcasts.com Results of Operations for the Three Months Ended March 31, 1999
and 2000

   Webcasts.com was incorporated in 1995 and commenced its current web
production services business in 1997. Webcasts.com revenues increased from
$0.7 million in the first quarter of 1999 to $1.6 million in the first quarter
of 2000 primarily as a result of its acquisition of The Rock Island Group,
Inc., or RIG, and higher production services revenue. Webcasts.com cost of
revenues increased from $0.3 million in the first quarter of 1999 to $1.7
million in the first quarter of 2000, and its operating expenses increased
from $0.5 million in the first quarter of 1999 to $3.2 million in the first
quarter of 2000 primarily due to the RIG acquisition, additional employees,
increased selling expenses and stock-based compensation. As of March 31, 2000,
webcasts.com had an accumulated deficit of $8.0 million.

iBEAM's Results of Operations for the Period from March 20, 1998 (Inception)
to December 31, 1998 and the Year Ended December 31, 1999

   Revenue. We began generating revenue in August 1999 after we commercially
introduced our content delivery service and have recognized $149,000 through
December 1999. Fees for On-Stage, On-Air and On-Demand services accounted for
74%, 6% and 3%, respectively, of total revenue for the year ended December 31,
1999. As we continue to expand our network and as more companies distribute
content over our network, we expect our revenue will increase in future
periods. We also expect our On-Air and On-Demand services will increase as a
percentage of total revenue, while On-Stage and other services will decrease
as a percentage of total revenue.

   Cost of Services (Direct and Indirect). Cost of services increased from
zero in 1998 to $7.5 million in 1999. This increase was primarily due to
network bandwidth, satellite transmission, co-location and content acquisition
expenses of $1.4 million, network server and software depreciation of $0.8
million, consulting expenses of $0.7 million and salaries, bonuses and related
taxes of $2.4 million as we began to deploy and manage our network in 1999.
Headcount included in cost of services rose from zero at December 31, 1998 to
73 at December 31, 1999.

   Engineering and Development. Engineering and development expenses increased
by $2.8 million, or 190%, from $1.4 million in 1998 to $4.2 million in 1999.
This increase was primarily due to an increase in salaries and related taxes
of $1.0 million as additional engineers were hired in 1999. Headcount included
in engineering and development rose from 23 at December 31, 1998 to 45 at
December 31, 1999.

   Sales and Marketing. Sales and marketing expenses increased by $8.0
million, or 448%, from $1.8 million in 1998 to $9.8 million in 1999. This
increase was primarily due to salaries, bonuses and related taxes of
$2.9 million and advertising and promotional expenses of $4.5 million,
resulting from the development of a sales and marketing organization and the
marketing of our network and corporate brand, which was publicly launched in
October 1999. Headcount included in sales and marketing rose from 13 at
December 31, 1998 to 36 at December 31, 1999.

   General and Administrative. General and administrative expenses increased
by $2.4 million, or 221%, from $1.1 million in 1998 to $3.5 million in 1999.
This increase was primarily due to salaries and related taxes of $1.0 million
as we began to provide infrastructure to support our growing operations.
Headcount included in general and administrative rose from six at December 31,
1998 to 21 at December 31, 1999.

   Amortization of Stock-based Compensation. Amortization of employee stock-
based compensation increased by $4.9 million from $31,000 in 1998 to $5.0
million in 1999 due primarily to the grant of stock options to newly hired
employees. In connection with the grant of stock options to consultants, we
recorded stock-based compensation expense of $8,000 in 1998 and $0.4 million
in 1999.

   Other Income and Expense, Net. Other income and expense, net increased from
$125,000 in 1998 to $200,000 primarily due to an increase in interest income
based on larger cash balances.

   Income Taxes. We have incurred operating losses for all periods. As of
December 31, 1999, we had net operating loss carryforwards for federal and
state tax purposes of approximately $25.8 million. These federal and state tax
loss carryforwards are available to reduce future taxable income and expire in
varying amounts beginning in 2004. Under the provisions of the Internal
Revenue Code, some substantial changes in our ownership may limit the amount
of net operating loss carryforwards that could be utilized annually in the
future to offset taxable income.

   Net Loss. Net loss increased by $25.8 million from $4.2 million in 1998 to
$30.0 million in 1999. The increase in net loss is primarily attributable to
increases in operating costs and expenses of $26.0 million, which includes an
increase in amortization of stock-based compensation of $5.4 million.

Webcasts.com Results of Operations for Years Ended December 31, 1998 and
December 31, 1999

   Webcasts.com had total revenue of $2.0 million in 1998 and $2.4 million in
1999. Webcasts.com costs of revenues increased from $1.3 million in 1998 to
$1.8 million in 1999, and its operating expenses increased from $0.9 million
to $4.8 million primarily due to increased selling expenses partially as a
result of its acquisition of the RIG and stock-based compensation. As of
December 31, 1999, webcasts.com had an accumulated deficit of $4.4 million.

Liquidity and Capital Resources

   Since inception, we have funded our operations primarily through capital
lease obligations and the sale of our capital stock. We have raised an
aggregate of $96.1 million from the sale of our preferred stock through
March 31, 2000.

   Net cash used in operating activities was $3.2 million in 1998 and $19.2
million in 1999, resulting primarily from our net loss partially offset by an
increase in accounts payable and accrued liabilities of $2.2 million,
amortization of stock-based composition of $5.4 million, depreciation and
amortization of $1.7 million and the issuance of a warrant for $1.0 million.

   Net cash used in investing activities was $1.5 million in 1998, resulting
from the purchase of property and equipment. Net cash used in investing
activities was $12.5 million in 1999 and consisted of $7.5 million in
purchases of computers, equipment for network infrastructure and software and
$5.0 million of investments of surplus funds received from the issuance of our
preferred stock.

   Net cash provided by financing activities was $6.9 million in 1998 and
$54.3 million in 1999. Cash provided by financing activities was the result of
net proceeds from the sales of our preferred stock and, to a lesser extent,
our common stock, partially offset by payments on our capital lease
obligations in 1999.

   As of March 31, 2000, we had approximately $21.8 million in cash, cash
equivalents, and investments. We expect the build-out of a global network and
the funding of operations to develop and to market our services will require
substantial investment. As of March 2000 we had raised $96.1 million from the
sale of preferred stock and $10.1 million from equipment lease lines that are
repayable over periods of up to four years. We expect to make at least $40.0
million in capital investments in 2000, of which $26.0 million was spent in
the first quarter to date, and will require significant capital to fund other
operating expenses. We expect to raise enough proceeds from our initial public
offering to fund our operations for at least 12 to 18 months. In the absence
of a public offering, to continue to execute our current business plan, we
would attempt to raise capital in the private equity market. To the extent
such capital is not available, or until available, we would exercise control
of our discretionary expenses by reducing network costs, capital expenditures
and other discretionary expenses. Thereafter, we will need to raise additional
capital in 2001 and we may seek to raise additional capital sooner. Since our
expenditure levels will depend on discretionary factors within our control and
competitive factors outside our control we are not able to determine the
amount of future capital we will need to raise with a high degree of
certainty.

Qualitative and Quantitative Disclosures About Market Risk

   We offer our services in the United States and anticipate distributing
U.S.-based content in Asia and Europe in 2000. As a result, our financial
results could be affected by factors including weak economic conditions in
foreign markets. Our interest income is sensitive to changes in the general
level of U.S. interest rates. Due to the short-term nature of our investments,
we believe that there is no material risk exposure; therefore, no quantitative
tabular disclosures are required.

Year 2000 Readiness Disclosure

   The year 2000 issue is the potential for system and processing failures of
date-related data and is the result of the computer-controlled systems using
two digits rather than four to define the applicable year. For example,

                                      34
<PAGE>

computer programs that have time-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices or
engage in similar normal business activities.

   We have designed our network and our service for use in the year 2000 and
beyond. To date, our service and our networks have not revealed any
significant year 2000 problems. Our network generally integrates sophisticated
hardware and software products incorporating the latest technologies at the
time of purchase.

   As of March 31, 2000 we have not experienced any significant costs as a
result of year 2000 problems and do not anticipate incurring material
incremental costs in future periods due to such issues.

Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued SFAS No. 133,
"Accounting for Derivative Instruments and Hedging Activities," which
establishes accounting and reporting standards for derivative instruments and
hedging activities. It requires that an entity recognize all derivatives as
either assets or liabilities in the balance sheet and measure those
instruments at fair value. To date, we have not engaged in derivative and
hedging activities, and accordingly, do not believe that the adoption of SFAS
No. 133 will have a material impact on our financial statements and related
disclosures. We will adopt SFAS No. 133 as required by SFAS No. 137, "Deferral
of the Effective Date of the FASB Statement No. 133," in our fiscal quarter
beginning July 1, 2000.

   In December 1999, the Securities and Exchange Commission issued SAB No.
101, "Revenue Recognition in Financial Statements," which provides guidance on
the recognition, presentation, and disclosure of revenue in financial
statements filed with the SEC. SAB No. 101 outlines the basic criteria that
must be met to recognize revenue and provides guidance for disclosures related
to revenue recognition policies. We have complied with the guidance in SAB No.
101 for all periods presented.

   In March 2000, the Financial Accounting Standards Board issued
Interpretation No. 44, "Accounting for Certain Transactions Involving Stock
Compensation -- an interpretation of APB Opinion No. 25". This interpretation
clarifies the definition of employee for purposes of applying Accounting
Practice Board Opinion No. 25, Accounting for Stock Issued to Employees, the
criteria for determining whether a plan qualifies as a noncompensatory plan,
the accounting consequence of various modifications to the terms of a
previously fixed stock option or award, and the accounting for an exchange of
stock compensation awards in a business combination. This interpretation is
effective July 1, 2000, but certain conclusions in this interpretation cover
specific events that occur after either December 15, 1998, or January 12,
2000. We believe that FIN 44 will not have a material effect on the financial
position or results of operation.

                                   BUSINESS

Overview

   We provide an Internet broadcast network that delivers streaming media to
large audiences of simultaneous users with viewing and listening quality that
can approach that of television and radio. Our network uses a combination of
land-line networks and point-to-multipoint satellite broadcasting of Internet
content to iBEAM servers located at the edge of the Internet, which is the
Internet access point closest to the end user. Our network broadcasts to iBEAM
servers located in the facilities of Internet service providers, or ISPs, and
other companies that host Internet applications and services. Our approach of
using a combination of land-line networks and satellite broadcasting to
deliver content directly to the edge of the Internet bypasses much of the web
congestion and improves the delivery of streaming audio-visual media and the
quality of the viewing and listening experience.

   We provide a wide range of services to our customers to facilitate their
use of streaming media on the Internet, including event production and
broadcasting services. To expand our service offerings to our customers, we
have acquired and developed software and interface tools that enable us to
broadcast high-fidelity video and audio streams integrated with e-commerce
links and functions. Our investment in servers at the edge of the Internet
also allow for the development of new value-added services in the future such
as pay-per-view event programming, advertising to targeted end users and
interactive Internet-based training.

   In April 2000, we acquired webcasts.com to add business-to-business
communications capabilities, such as online training and interactive trade
shows. Our combined technology allows users to view streaming content,
interactively obtain related data and transact online purchases. Our
technology runs with a variety of streaming media players. Most Internet users
can access our streamed content regardless of the users' multimedia and
browsing software and end users do not need to purchase special equipment. As
of March 31, 2000, our network, which we will continue to develop, is
sufficient to support up to 300,000 simultaneous Internet users accessing
streams of data from the Internet at 20 kilobits (20,000 bits) per second. We
plan to expand our network to support 1,000,000 simultaneous Internet users at
this rate by the end of 2000.

   We commercially introduced our service in October 1999. We currently have
contracts to provide our services to over 100 content providers. We generate
revenue from our broadcasting services based on the volume of content stored
or delivered to end-users and from our other services such as event production
based on hourly or fixed price billing. As part of the build-out of our
broadcasting network, we have agreements to locate our servers with over 90
ISPs including America Online, the largest U.S. Internet access provider,
Excite@Home, an Internet cable access provider, and Covad Communications and
Northpoint, high-speed Internet access providers that have developed networks
with national reach. To realize the benefits of these access agreements we
will need to make substantial investments in capital equipment located at ISPs
and pay some of those ISPs fees based on revenue derived from their networks.
In January 2000, we entered into a letter of intent with Pacific Century
CyberWorks, or PCCW, to establish a joint venture, named iBEAM Asia, to expand
our international presence and to access PCCW's network of cable subscribers.

Industry Background

   The Internet has evolved from a static information source to a dynamic
medium for commerce, communications and, most recently, media. However, the
Internet was not designed to support the delivery of full motion video and
high-fidelity audio simultaneously to large audiences. To date, Internet
broadcasts have been inferior to television and radio broadcasts due to high
Internet transmission costs, the low quality of the viewing and listening
experience and the inability to serve large audiences of simultaneous users.
Despite these limitations, existing and new website owners, traditional media
and entertainment companies and creators of new applications, such as online
education, are trying to attract and retain Internet users by using greater
amounts of visual and audio content on their websites. Streaming has become
the preferred method of distributing video and audio content because it allows
simultaneous broadcasting and playback of content, thereby eliminating the
requirement that an Internet user download an entire video or audio file
before viewing or listening.


                                      36

   Burgeoning Demand for Streaming Media

   Owners of Existing Websites

   Owners of existing websites are trying to attract and retain users with
rich content. Richer content, such as an audio sample of a compact disc music
recording or a video demonstration of a product, combined with the interactive
and user-controlled capability of the Internet, are factors that increase
consumer interest and purchases. This enriched content is made possible
through streaming media. New media companies have emerged to address the
growing audience of Internet users with news and entertainment content. RHK
Research recently reported in a press release that streaming media now
comprises 10% of total Internet traffic.

   Traditional Media and Entertainment Companies

   Traditional media and entertainment companies are emerging as another
factor driving the demand for Internet distribution of streaming content. This
demand is in part to provide new content and to retain existing audiences
which are increasingly finding the Internet an attractive alternative to
television. Forrester Research recently reported that consumers between the
ages of 16 and 24 believe they watch 47% less television because of the
Internet.

   Platform for New Applications

   The demand for streaming media, at both the enterprise and consumer level,
will be driven by a host of new applications that currently are under
development or are not yet commercially available for sustained online usage.
At the enterprise level, corporate broadcasts, sales calls and product
launches are increasingly incorporating sophisticated web pages and streaming
media to reduce the number of face-to-face meetings, with the goal of
generating significant savings in planning and travel costs. Other enterprise-
wide processes being migrated onto the Internet include business-to-business
transactions such as ordering, purchasing, auctions, supply chain management
and large file distribution. Enterprises and educational institutions are also
offering streaming training videos on the web to facilitate Internet-based
distance learning. We believe that the ability to view and hear streaming
media on-demand will also drive consumer demand for other online products and
services such as advanced video games, interactive television and pay-per-view
events.

   Internet Design Limitations for Streaming Media

   The Internet was originally designed to ensure delivery of static data,
such as text and data files, and was not designed to ensure the continuous
flow of streaming media. The Internet's design goal of ensuring bulk data
delivery is accomplished by breaking transmissions into small packets of data
that can be routed through different delivery points at different times and,
subsequently, be interwoven with other data transmissions. Should an Internet
connection point, such as a server or router, receive traffic that exceeds its
capacity, packets are dropped temporarily. These "lost" packets are either
lost permanently or are eventually requested and re-sent, but the sequence of
receipt may be out of order and irregularities may occur in intervals of
receipt. Due to limited capacity on the Internet, today most streaming content
is transmitted in the UDP, or user datagram protocol, format where lost
packets are not recovered.

   While static web pages can experience lost packets or delays without a
noticeable deterioration in quality, streaming media is much more sensitive to
these problems. The impact of packet loss and irregular latency causes a
"jitter" in viewing and listening to streaming media as streams stop and
restart waiting for packets to arrive. In addition, lost packets may include
"key frames" in the content that contain information needed to ensure the
proper decoding and playback of subsequent frames.

   The rate of packet loss is significant on the Internet. In a 1998 Bell Labs
Study, packet loss rates of approximately 25% occurred during peak periods. We
believe packet loss will increase if traffic growth exceeds the addition of
server and router capacity. In addition, rapid deployment of high-speed
connections, such as DSL and cable modems, which are intended to improve the
viewing and listening experience of the end user, are

                                      37
<PAGE>

increasing the traffic load on the Internet causing further congestion and
quality degradation. We believe that increasing packet loss and more high-
speed Internet connections are combining to significantly degrade the end
user's streaming media experience.

   Cost and Scale Factors Limiting Streaming Media

   To date, Internet broadcasts have been inferior to television and radio
broadcasts due to high Internet transmission costs, the low quality of the
viewing and listening experience, and the inability to serve large audiences
of simultaneous users. This is largely due to the current single point-to-
point land-line network model for Internet content delivery. In a point-to-
point network, each end user establishes a connection between his personal
computer and the computer originating the content delivery. Because of the
need for connectivity to each individual end user, content providers must make
large investments to support the bursts in demand that may sit idle during
non-peak periods. Often the amount of investment required is either difficult
to estimate or uneconomical to make. As a result, during periods of peak
demand for content, insufficient Internet user connections may prevent access
by many users to popular events. For example, many users trying to access the
Victoria's Secret fashion show and the John Glenn space shuttle launch over
the Internet experienced these problems.

   The Internet requires users to pay multiple tiers of communication
providers for long distance and local access which results in multiple charges
and higher costs. Communication providers charge based on bandwidth, which is
the capacity of the communications line required to transmit a given amount of
data. Both the party sending data on the Internet and the ISP receiving
content into its network pay these charges. Streaming media, which is
inherently data rich and typically consumes multiple times the bandwidth of
static web pages, increases costs for content providers and ISPs. As an
example, we believe the cost of a transmission to a content provider of
streaming media that approaches the quality of a VCR video (a 300 kilobit
stream) would typically exceed advertising revenue derived by the content
provider from such transmission. Our belief is based on discussions with
Internet advertising specialists, which indicate that content providers will
receive approximately $40 in advertising revenue for each 30 seconds of
advertising in a three minute broadcast segment to 1,000 users, and our own
experience in purchasing capacity in the communications bandwidth market,
which indicates that the average cost of transmitting content to these 1,000
users for each three minute broadcast segment is approximately $70. In
addition, ISPs that are typically bound to fixed monthly revenues under their
contracts with end users may see their costs increase as their customers
access increasing amounts of streaming media. While we believe that land-line
data transmission cost will decline significantly over time, we also believe
the land-line networks are unlikely to approach the economies of scale
achieved by alternatives, such as point-to-multipoint broadcasting by
satellite, where there is no direct transmission cost of adding an additional
broadcast viewer.

   Limitations of Current Approaches to Delivering Streaming Content

   While various products and delivery services have been developed to address
the challenges of delivering streaming content, we believe they do not
adequately resolve the issues of quality, cost and scalability. Some content
hosting companies store and locate streaming content on servers located at
multiple points on the Internet closer to end users. This typically increases
the speed of connection to a user. However, it does not eliminate the
potential for packet loss as content is delivered from these servers to the
end user through the remaining Internet connections. In addition, both product
companies and hosting companies offer caching software or services that store
content most frequently requested by users closer to the user in order to
reduce the transmission costs across the Internet. This usually requires a
large investment in caching software, offers only limited improvements for
live streaming content and lacks other capabilities such as forward error
correction, which is the ability to detect and correct errors in data
transmissions before such data reaches the end users. Furthermore, it does not
generate reporting and network management data for content providers.

   Many traditional communications or Internet backbone providers have been
trying to increase their network capacity. However, these fiber-optic networks
do not offer a complete managed service and rely on network connections that
are subject to packet loss and quality degradation. In addition, some of the
webcasting companies have proposed to lower transmission cost by having ISPs
agree to retransmit content in a daisy chain approach. This

                                      38
<PAGE>

approach does lower cost, but propagates packet loss and errors as data is
transmitted to the next ISP. Also, while these approaches offer some benefits
for data which can be stored and retransmitted, neither the traditional web
hosting providers, the caching technologies nor the new fiber-optic based
networks are currently capable of large scale, high fidelity Internet
broadcasting. Our Internet broadcast network leverages the best attributes of
many of these approaches and combines them with our proprietary streaming
software to deliver cost effective streaming media broadcasting that offers
high fidelity content distribution to large numbers of simultaneous users.

The iBEAM Solution

   We provide an Internet broadcast network that delivers streaming media with
viewing and listening quality that can approach that of television and radio.
Our broadcast network offers content providers the ability to serve large
audiences of simultaneous users. Our network uses a combination of land-line
networks and satellite broadcasting to deliver Internet content to iBEAM
servers located at the edge of the Internet, which is the Internet access
point closest to the end user. This improves the quality of the broadcast
stream by avoiding Internet congestion. Our satellite broadcast approach and
streaming management software bypasses the congestion of the Internet
backbone. We provide a wide range of services to our content provider
customers to facilitate their use of streaming media on the Internet. Our
investment in servers at the edge of Internet enables the delivery of new
value-added services, such as advertisement insertion, to both the content
providers and ISPs. We also provide production, event management, encoding and
acquisition services to facilitate use of our broadcasting services by content
providers.

   The key benefits of our streaming media services to our customers include:

  .  High-Fidelity Video and Audio Streams--Our satellite broadcasting
     capability and our software enable smooth, continuous content delivery
     to our servers before being transmitted to the end user. By delivering
     content to the edge of the Internet, our network eliminates packet loss
     and jitter, thereby delivering a superior broadcast-quality stream.

  .  Low Cost Distribution--Using satellite technology to broadcast on a
     point-to-multipoint basis at a fixed cost allows us to broadcast to each
     additional user at little or no incremental cost. This economy of scale
     lets us charge content providers less to distribute streaming media than
     traditional Internet bandwidth providers that rely on land-line point-
     to-point connectivity and may enable content providers to improve their
     profitability.

  .  Ability to Serve Large Audiences Simultaneously--Our network of servers
     and our use of satellite technology to transmit a single stream to an
     unlimited number of servers are designed to allow us to serve large
     audiences of simultaneous users. As we add streaming capacity through
     additional investments in servers and hosting center equipment, we will
     be able to serve increasingly larger audiences with the quality and
     reliability that both end users and content providers demand.

  .  No End User Special Equipment Needed--Since we broadcast to the ISPs,
     end users do not need to purchase receiver dishes, special software or
     change their procedures to view content. This makes our services
     transparent to the end user and we believe facilitates the rapid
     deployment of our network.

  .  Broad Range of Service Offerings to Facilitate Use of Streaming Media--
     Our streaming media services for content providers consist of, among
     other things, production, event planning, encoding and production
     services. The acquisition of webcasts.com will supplement our service
     offerings by giving us the capability to integrate chat and e-commerce
     databases with streaming media content and by adding to our other
     services. Our customers do not need to utilize multiple vendors to
     enable their websites to offer streaming media.

  .  Usage Reporting Capabilities--We have developed a web-based network
     dashboard that allows content providers to determine, by individual
     stream, who is watching or listening to their content, how long they
     have been watching or listening and where the user is geographically
     located. This dashboard gives content providers on our network the
     insight they need to make intelligent programming and

                                      39
<PAGE>

     advertising decisions, which is a great advantage compared to the
     traditional rating services relied on by media companies.

  .  Network Supports a Variety of Technologies and Applications--Our network
     is designed to support all streaming media applications. We support the
     major streaming media players including Windows Media Player and
     RealPlayer and we intend to support new players as they gain widespread
     market acceptance. Our servers deployed throughout the Internet can
     execute a variety of value-added applications. Our server platform is
     designed to be highly flexible, allowing for new services and
     applications such as streaming advertising insertion, pay-per-view
     administration and other e-commerce related services. These new
     applications will create the potential for new revenue sources for our
     customers.

Strategy

   Our goal is to become the leading provider of high-fidelity Internet
broadcast services by developing the world's largest, premier quality, and
most cost efficient distributed streaming network. To this end, we are
capitalizing upon our innovative network architecture, proprietary technology
and early entry into streaming media broadcasting to position us as the
broadcast network of choice for reliable, high-fidelity Internet broadcasting.
Our strategy comprises the following initiatives:

   Expand Our Customer Base. We currently have contracts to provide our
services to over 100 media, entertainment and technology companies. We intend
to increase our customer base by targeting existing new media, entertainment,
and e-commerce companies, as these companies begin to more fully use streaming
technology. We also intend to target traditional media and entertainment
companies, including motion picture, television, sports, newspapers and radio
companies, as customers, which we believe will increasingly seek to broadcast
video and audio over the Internet. To accomplish these goals, we intend to
expand our sales force and to further invest in marketing activities and
services and building the iBEAM brand. The acquisition of webcasts.com expands
our customer base by adding customers that use webcasts.com's business-to-
business e-commerce services including Lotus/IBM and America Online, which
were its largest customers by revenue in 1999.

   Globally Build Out Our High-Fidelity Internet Broadcast Network. We plan to
build out our network internationally through joint ventures, partnerships and
other commercial arrangements with global technology and media companies that
have the local resources and expertise to extend our broadcast network to
international customers. This will serve to increase the worldwide number of
users that can be reached by our edge servers, yielding high quality
transmission at low cost. We believe our satellite-based business model will
be particularly successful in markets with less developed, land-line
infrastructure. We believe that the recent growth in Internet and data related
transmission in the United States will be repeated in numerous regions across
the globe, including Europe, Asia and Latin America. In January 2000, we
signed a letter of intent with Pacific Century CyberWorks, or PCCW, to
establish a joint venture company called iBEAM Asia. iBEAM Asia, which will be
51% owned by PCCW and 49% owned by iBEAM, will focus on distributing streaming
video and audio content in over 50 countries in the Pacific Rim, Indian
subcontinent and Middle East. iBEAM Asia expects to provide its distribution
services to Pacific Convergence Corporation, or PCC, as well as other ISPs in
these regions by the end of 2000. PCC, a provider of broadband Internet
access, online content and e-commerce services in Asia, is being acquired by
PCCW. As a result, iBEAM Asia's deployment of its edge network will initially
parallel the build-out of PCC's Internet services to cable operators that
subscribe to PCCW's broadband ISP platform and related Internet services. To
date, PCC has not launched their Internet services. iBEAM Asia intends to
predominantly use satellite distribution rather than land-lines because of the
relatively high cost of land-line bandwidth in Asia. In addition, we recently
entered into an agreement with Interpacket, a satellite-based IP network
serving ISPs in 80 countries, to deliver our customers' streaming content via
Interpacket points of presence in Asia, Europe, Latin America, Africa and the
Middle East.

   Further Leverage Our Broadcast Network to Drive Economies of Scale. We have
developed a proprietary software platform that enables a number of standard
Internet applications to be run across a global

                                      40
<PAGE>

network of distributed edge servers. The inherent advantage of our network and
its associated satellite broadcast software platform is its ability to allow
standard Internet applications to reach large audiences. As we continue to
deploy and increasingly operate through our point-to-multipoint network
architecture, we will be able to broadcast increasing amounts of content to
our highly distributed network of servers with minimal, incremental satellite
transmission cost.

   Moreover, we can add additional points of presence, which are server
locations at an Internet users' access point within an ISP network, with low
capital expenditures and minimal increase in bandwidth costs. By leveraging
the existing infrastructure of local and regional Internet service providers
to carry our network traffic, we further reduce the expenditures we incur in
deploying our network infrastructure. Our broadcast network offers several
advantages to ISPs. By partnering with us, ISPs can avoid incoming bandwidth
charges and provide significantly improved end user experiences through our
broadcast network. This quality and cost advantage will enable us to continue
penetrating the streaming media content distribution market.

   Introduce New Value Added Features and Services. In addition to offering
high-fidelity streaming at competitive prices, we believe we can attract new
streaming media customers through the introduction of advanced features such
as real-time traffic reporting and advanced data management that simplify the
task of streaming content on the Internet. We intend to aggressively pursue
these new applications and new markets. An example of a new application we
recently introduced is the ability to enable content providers to insert
targeted and non-targeted streaming advertising into our broadcasts. Our
servers now have the capability to insert directed local advertisements into
each copy of the broadcast stream they serve. We believe that this capability
will allow content providers to enhance their revenue by charging advertisers
a premium for advertising targeted directly to the end user. We expect to
generate revenue from targeted advertising during the second quarter of 2000.
In addition, we intend to serve enterprise customers with needs for new
applications such as Internet enabled distance learning, virtual roadshows,
digital downloads and video conferencing.

   Pursue Additional Commercial Relationships and Joint Ventures. We currently
have commercial relationships with various media, entertainment and technology
companies and ISPs, including America Online, Covad Communications, Microsoft,
Pacific Century CyberWorks and Sony. These relationships provide us with
insights as to future customer requirements, Internet access trends and
emerging technologies and facilitate our network expansion. For example,
through our agreement with America Online, we will be able to deploy our
servers throughout the largest U.S. Internet access network, thus expanding
the reach of our broadcast platform. This will, in turn, make our services
more attractive to content providers, which will be able to reach more end
users through our network. We intend to pursue additional commercial
relationships to accelerate market acceptance of our services and expand our
global network. We believe that these benefits, combined with what we believe
will be the ISP's unwillingness to accommodate multiple distributed networks,
will strengthen our competitive position.

   Create Open Platform for New Applications. A network of distributed
computers located at the edge of the Internet can run a wide range of
applications more efficiently than a traditional approach of running these
applications on a cluster of servers located in one or a few data centers
located on the Internet backbone. We are developing a series of application
programming interfaces that allow other applications from other providers to
take advantage of our network. We believe the open architecture of our network
will encourage other application service providers to partner with us.

iBEAM's Streaming Media Services

   Distribution Services

   We currently offer three primary services: iBEAM On-Air, iBEAM On-Stage and
iBEAM On-Demand. These services are typically charged based on the volume of
content delivered to end users as measured in

                                      41
<PAGE>


megabytes or megabits consumed and therefore varies with the number of
viewers, the access speeds of the viewers and time viewers spend viewing
content broadcast by us. Currently, On-Air and On-Demand services are
typically priced based on actual usage, which is measured by the volume of
megabits transferred during the month, for which we typically charge $.005 to
$.01 per megabyte per month, subject to a minimum payment. In addition, for
On-Demand customers, there is a monthly fee for content stored on our network,
which is measured in gigabytes. On-Stage can be priced under a fixed-fee
arrangement or on actual usage in terms of megabits transferred. To date,
content providers have typically elected to enter into fixed-fee arrangements
in order to fix the price of a broadcasting event. We price our fixed-fee
arrangements using an estimate of the amount of content delivered, which
includes a forecast of the expected number of viewers, the access speeds of
the viewers and the duration of the event. We typically charge $.005 to $.01
per megabyte transferred for our On-Stage services. Other services such as
production, event management, encoding and acquisition services, are generally
provided on a consulting basis on either an hourly or fixed price billing.

   iBEAM On-Air. iBEAM On-Air is the service offered for delivery of live,
continuous content streaming, such as music video channels, Internet or
traditional radio stations or news shows and sports channels. iBEAM On-Air
service is highly differentiated since it is very difficult to deliver live
content across the Internet using existing Internet delivery or caching
technologies. Video and audio streams are typically delivered by satellite to
our servers, which we call MaxCasters, bypassing the congestion of the
Internet backbone. The satellite link and our private acquisition network
allow us to offer an end-to-end connection from content source to the ISP
ensuring high fidelity video and audio streams. We derived 6% of our revenue
in 1999 from our On-Air services.

   iBEAM On-Stage. iBEAM On-Stage is the same live delivery of iBEAM On-Air,
but packaged to meet the needs of the event-based customer. Target customers
for iBEAM On-Stage include concerts, trade shows and other events. Our network
is particularly important for high profile live events, such as the Metallica
1999 concert, since the large number of simultaneous users attracted by these
events often causes wide-spread congestion in the Internet backbone. Our
satellite broadcast capability allows us to bypass this congestion and deliver
a high-fidelity stream, even during periods of peak usage. We derived 74% of
our revenue in 1999 from our On-Stage services.

   iBEAM On-Demand. iBEAM On-Demand is our service for on-demand media
hosting, such as music video clips, news highlights, product displays or any
type of streaming media included on a website. iBEAM On-Demand service is
based upon our network agent iDirector that manages the replication of stored
on-demand content across the array of iBEAM MaxCaster servers. Our network has
been designed with large-scale storage capabilities to accommodate the very
large content libraries of the media companies we serve. We derived 3% of our
1999 revenue from our On-Demand services.

   Other Services

   To supplement our core distribution services, we offer a series of other
services aimed at facilitating a complete Internet broadcasting solution for
content providers. Our services include targeted advertising, production,
event management, encoding and acquisition services. These services are
typically billed on a consulting or usage basis.

   Targeted Advertising Services. We recently introduced our iBEAM On-Target
services through which we enable content providers to insert streaming
advertisements targeted toward the end user in our broadcast streams.

   Production Services. We have a team of service consultants and tools that
enable the creation and management of user interfaces that enable the
integrated presentation of streaming media, chat boxes, e-commerce links and
access management controls.

   Event Management Services. We have a team of event managers that will
travel to the site of broadcast events. These event managers will supervise
the interface with the content production crew, as well as provide on-site
encoding and signal acquisition.

   Encoding Services. Encoding is the process of converting a raw digital
audio or video stream into a format optimized for delivery over the Internet.
Proper encoding is critical to ensure the highest fidelity streaming

                                      42
<PAGE>

content. Optimizing the encoding process requires a combination of
quantitative and subjective assessments of the content being encoded. We
provide these services directly and indirectly through qualified third-party
vendors such as Loudeye and Entertainment Blvd.

   Acquisition Services. Our acquisition services collect content from content
providers for distribution through our network. We offer a variety of signal
acquisition methods. In some instances, we will procure the acquisition
circuits on behalf of our customers.

Customers

   We commenced commercial operations in October 1999. We currently have
contracts to provide our services to over 100 content providers. The following
is a partial list of our customers and webcasts.com's customers by category in
order of amount of revenue generated in 2000 through March 31, 2000:

</TABLE>

   The following case studies illustrate how some of our largest customers, in
terms of the amount of content distributed through our network, are using our
service offerings.

   Microsoft

   When Microsoft launched its Windows Media Technologies version 4, they
promoted the launch event by hosting a live concert with Buddy Guy, a popular
blues guitarist which highlighted our capability to broadcast live events that
require high fidelity streaming video. We provided iBEAM On-Stage service to
Microsoft to broadcast a broadband video feed from the concert at the House of
Blues in Los Angeles to our network of MaxCasters deployed around the country.

   Launch Media

   We were chosen by Launch Media to provide iBEAM On-Demand hosting services
to deliver stored music through our network for the recently introduced
Launchcast personalized music service. This service allows users to specify
what genre of music they prefer and identify individual titles they want
included in their personal playlist. Hosting the Launchcast music service
makes extensive use of the intelligent data management of iBEAM On-Demand. The
Launchcast service supports a very large library of digitized music,
intelligently stored across our distributed network.

                                      43
<PAGE>

   MSNBC

   MSNBC utilizes the high bandwidth capabilities of iBEAM On-Air to broadcast
news coverage through our network. MSNBC's continuous live video news feed is
streamed over our network. We also deploy and update news highlights that are
available on-demand to MSNBC users. In December 1999, a single 100 kilobit per
second (kbps) video stream served by us generated nearly one terabyte of
streaming media data to MSNBC users.

Internet Broadcast Network

   The architecture of our network is conceptually similar to the architecture
of traditional broadcast television and cable networks but incorporates
several layers of redundancy. Traditional television is collected over a
private acquisition network, then broadcast by satellite to television
affiliates or cable facilities geographically dispersed around the country. We
collect streaming Internet content from providers, then broadcast it via
satellite and traditional land-line networks to our network of MaxCasters,
located in the facilities of ISPs. We then deliver these high-fidelity video
and audio streams to the end-user. Our services require no special end user
hardware or software. In addition to the efficient distribution of streaming
content, our MaxCasters can perform a wide range of value-added applications,
such as targeted advertising and integrating e-commerce links with streaming
content, which we will seek to introduce in the future.

   As we expand our network of MaxCaster edge servers, we will increase the
number of users served, thereby reducing transmission costs to ISPs. We have
currently deployed servers in more than 90 networks. These service providers
include ISPs such as America Online, DSL providers such as Covad
Communications and Northpoint, cable modem service providers such as High
Speed Access and backbone providers such as Apex Global Internet Services.
Under agreements with ISPs, we have agreed to deliver content into their
networks at no charge, unlike network bandwidth providers that charge ISPs for
delivery of content. Furthermore, in some cases, we share a portion of our
revenue derived from content providers with the ISP. As of March 31, 2000, we
pay fees to less than 50% of the ISPs with which we have contracts. These fees
range from 15% to 20% of the revenue we derive from content delivered through
their network. Because the ISPs to which we pay fees tend to be the ISPs with
larger networks, we believe that as we expand our network we will pay fees
with respect to more than 50% of the Internet traffic delivered through our
network.

   In addition to our network of MaxCaster edge servers, we have deployed a
series of regional hosting centers. The regional hosting centers are deployed
at strategic locations around the Internet backbone. They are designed to
reach users not served by a MaxCaster edge server. In addition, these hosting
centers provide a second tier of redundancy--if the MaxCaster is unavailable
for any reason, users are automatically routed to our nearest regional hosting
center.

   The third layer of redundancy in our network is achieved by the deployment
of master hosting centers, which are located in co-location facilities of
companies such as Abovenet and Exodus Communications. The master hosting
centers provide a third layer of redundancy, filling in for any regional
hosting centers that may be unavailable for any reason. In addition, they have
large scale storage systems to host the complete content libraries of our
media customers.

   As of March 31, 2000, our network was sufficient to support up to 300,000
simultaneous end users. As of that date we estimate that less than 5% of
traffic delivered through our network was served by our edge servers. The
remaining content delivered to end users through our land-line network is
served from our regional or master hosting centers. We expect that this
percentage will decline significantly as we install additional servers on the
edge of the Internet. We expect that we will be able to serve up to 40% of end
users on our network through our edge servers by the end of 2000.

   Our geographically dispersed network of servers is monitored continuously
by our network operations center. We have developed a series of proprietary
network management tools that allow our network operations

                                      44
<PAGE>

center personnel to have complete visibility into any of our remote servers
and to remotely manage the servers. Our network operations center personnel
can diagnose problems, restart servers, and update or re-load software using
either land-line or satellite communications with the remote server. Our
network operations center is located in a hardened facility with back-up power
supplies and redundant systems.

Our Technology

   Since our inception in March 1998 through March 31, 2000, we have invested
$10.0 million on engineering and development activities, which has led to the
development of a series of software technologies that constitute the iBEAM
broadcast platform. An attribute of our broadcast platform is that it allows
any server in the network to deliver streams to any user on the network,
thereby avoiding the inefficiencies of dedicated servers only for specific
users.

   Some of the key components of our broadcast platform include:

   MaxCaster--the intelligent video and audio server at the network edge

   The primary technical component of the broadcast platform is the iBEAM
MaxCaster. The MaxCaster is the remote server that sits at the edge of the
Internet. The MaxCaster receives the 1-way satellite broadcast, and performs
functions that integrate the satellite broadcast with the 2-way traffic of the
Internet. The MaxCaster contains software that allows it to receive, store and
manage data, as well as report back to our network operations center on the
state of the server and the content being served. Finally, the MaxCaster can
process the content to perform functions, such as inserting streaming
advertising that is targeted to each individual end user.

   iRelay--the reliable transport layer

   The second element of our broadcast platform is the iRelay transport layer.
The iRelay transport layer allows us to accept an input from several types of
sources, including live audio or video feed and FTP file delivery, and deliver
it to all of our servers without the potential for packet loss or the
atmospheric disturbances of satellite transmission. If a packet should be lost
or scrambled during transmission, the iRelay software will re-transmit the
missing packet to any downlink that did not receive the original data. iRelay
is a key component in enabling us to harness the full broadcast power of
satellites to deliver uninterrupted Internet streams to large numbers of our
servers located close to the end user.

   iDirector--the intelligent network controller

   The third element of our broadcast platform is a proprietary technology
called iDirector. The iDirector technology is an intelligent agent that
receives the end user request for content. For example, if an end user goes to
msnbc.com to look at an MSNBC news feed, iDirector identifies where the end
user is located, then makes an assessment of network conditions, satellite
link availability, and server availability to connect the end user to the
optimal server. If any component of our network is down, the iDirector system
automatically routes the end user to a different part of the network to ensure
continued service.

Acquisition of webcasts.com

   In April 2000 we acquired webcasts.com, a provider of interactive
broadcasting services and proprietary tools that give businesses the ability
to conduct live and on-demand Internet broadcasts for use in distance
learning, corporate communications, sales presentations, online trade shows
and interactive television.

   Webcasts.com's service and tools offerings include:

    .  Vuser, a tool that allows a content provider to deliver an
       interactive presentation that combines streaming media, animation,
       graphics, banner advertising, e-commerce text and live Internet
       links in one interface;

                                      45
<PAGE>

    .  Audience management services, which include audience registration,
       pay-per-view and restricted access control; and

    .  Broadcast management services, which include event production
       assistance, provision of Internet connections and encoding for
       Internet transmission and event monitoring services.

   We believe the combination of our broadcasting services and webcasts.com
event production services will allow us to offer a broader range of services
to customers, intended to make it easier to initiate and continue broadcasting
on the Internet.

   Webcasts.com's customers include Lotus/IBM and America Online, which were
its two largest customers in 1999. Webcasts.com had 95 employees as of March
31, 2000.

Commercial Relationships

   We have commercial relationships with America Online, Pacific Century
CyberWorks, Covad Communications, Excite@Home, InterPacket, Microsoft
Corporation, and Sony Corporation, and intend to enter into additional
relationships with other media, entertainment and technology companies to
accelerate market acceptance of our services and to expand and enhance our
global network. We believe relationships with technology and media companies
can accelerate market acceptance of our technology and services, increase our
brand recognition and improve access to our target customer base. Among our
more important commercial relationships are those we have entered with large
ISPs and ISPs which provide high speed Internet access. The agreements are
critical to the success of our business model which is dependent on the
deployment of our servers to the edge of the Internet. In order to secure
agreements with large ISPs and high speed Internet access providers, in four
instances we have agreed to share with ISPs between 15% and 20% of the revenue
we derive from content delivered through their networks.

   America Online

   In February 2000, we entered an agreement with America Online to deploy our
streaming media distribution network within America Online's data centers. The
agreement will increase the availability of content delivered through our
network on the edge of the Internet. We will deploy our Internet broadcast
platform to deliver live streams into the America Online network, providing
America Online's members with direct access to streaming content through our
network. America Online has agreed to allow us to serve Internet end users who
do not subscribe to America Online from our servers located within America
Online's facilities. We have agreed to share with America Online a portion of
the revenue generated from delivery of content from our servers in their
network to end users, including America Online subscribers and non-
subscribers. In addition, if we exceed maximum allowable bandwidth amounts
with respect to content delivered to our servers located within the America
Online network and from such servers to non-subscribers, we have agreed to
make additional payments to America Online. We do not expect to make any
payments to America Online for excess bandwidth usage. We made non-refundable
prepayments of an aggregate of $3.0 million to America Online as an advance
against payments due to them under the agreement.

   In addition, in February 2000, we sold $5.0 million of our series E
preferred stock to America Online which will convert into 500,726 shares of
common stock upon the closing of the offering. America Online received a
warrant to purchase $5.0 million of our common stock at an exercise price
equal to the price to the public in this offering, less estimated underwriting
discounts and commissions, which at an assumed offering price of $10.00 per
share would be 537,634 shares.

   Covad Communications

   In October 1999, we entered into an agreement with Covad Communications, a
leading national broadband services provider utilizing digital subscriber line
(DSL) technology, to provide Covad with high-fidelity

                                      46
<PAGE>


streaming video and audio content at lower cost than communication providers
that operate only land-line networks. Under the terms of the agreement, we
will deploy our MaxCaster servers in Covad's network, which is in North
America, thereby enlarging the edge of our network. As part of this deployment
initiative, we have collaborated with Covad on technical efforts aimed at
enabling new services including quality of service management, subscriber
management and pay-per-view. We have agreed to share with Covad a portion of
the revenue derived from content delivered through their network.

   We sold 335,570 shares of our series D preferred stock to Covad for an
aggregate purchase price of approximately $2.0 million in October 1999 which
will convert into 1,386,239 shares of our common stock upon the closing of
this offering.

   Excite@Home

   In April 2000, we entered into an agreement with Excite@Home to deploy our
streaming media distribution network within the Excite@Home network as
Excite@Home completes its national data centers. The agreement also provides
for Excite@Home to deliver network connectivity services to iBEAM. We believe
the agreement will increase the availability of content delivered through our
network on the edge of the Internet. We have agreed to pay Excite@Home $2.5
million as a non-refundable prepayment for any services that are provided to
us under the agreement and the revenue we are obligated to share with
Excite@Home for content distributed through their network.

   In addition, in April 2000, Excite@Home agreed to purchase $5.0 million of
our series H preferred stock at a price equal to the price to the public in
this offering, less underwriting discounts and commissions. The series H
preferred stock will convert into common stock on a one-for-one basis at the
closing of this offering. Based on an assumed public offering price of $10.00
per share, Excite@Home will purchase 537,634 shares of our series H preferred
stock.

   InterPacket

   In January 2000, we entered into an agreement with InterPacket, a
satellite-based IP network serving ISPs in over 80 countries worldwide. Under
the agreement, InterPacket will deliver our customers' streaming content via
their global satellite broadcast network to MaxCasters at InterPacket points
of presence in Asia, Europe, Latin America, Africa and the Middle East. We
believe this relationship will enhance our service offerings and revenue
potential and InterPacket's revenue potential. We will benefit from this
relationship by accelerating international deployment of our network to the
edge of the Internet.

   Microsoft Corporation

   We entered into an agreement with Microsoft, effective as of September 20,
1999, to improve the delivery of streaming media over the Internet. Under the
agreement, Microsoft recommends us as a service provider for the delivery of
broadband streaming media and we will engage in cooperative sales efforts to
promote Windows Media Technology (WMT). Additionally, for the term of the
agreement, we have agreed to provide six months of our services to content
providers chosen by Microsoft, provided that the value of these services to
all to such content providers does not exceed $200,000 in the aggregate. We
cannot currently quantify the number of content providers to which we expect
to provide free services under this arrangement. In addition to our direct
sales efforts, we are collaborating on feature development, including
technical exchanges regarding the identification and development of new
functions to be included in either our NT based network platform or WMT. We
are provided early adopter access to new WMT products and agree to incorporate
and promote new competitive WMT features. We do not have an exclusive
arrangement under which Microsoft will not recommend any other service
providers for the delivery of broadband streaming media.

   Our agreement with Microsoft will extend through September 2002. Microsoft
has agreed to pay us $500,000 through April 15, 2000, all of which Microsoft
may use to purchase our services either for itself or on behalf of other
Internet content providers.

                                      47
<PAGE>

   We sold 1,677,852 shares of our series D preferred stock to Microsoft for
an aggregate purchase price of approximately $10.0 million in October 1999
which will convert into 6,931,206 shares of our common stock upon the closing
of this offering. In addition, we granted Microsoft a warrant to purchase
218,120 shares of series D preferred stock at an exercise price of $5.96 per
share which will convert into 901,053 shares of common stock.

   Pacific Century CyberWorks

   In March 2000, we signed a letter of intent with Pacific Century CyberWorks
Limited, a Hong Kong based Internet services and investment company, to
establish a joint venture company named iBEAM Asia. iBEAM Asia, which will be
51% owned by PCCW and 49% owned by iBEAM, will focus on distributing streaming
video and audio content in over 50 countries in the Pacific Rim, Indian
subcontinent and Middle East. iBEAM Asia plans to begin delivering content to
end users in Asia by the end of 2000.

   In addition, in February 2000, we sold $30.0 million of our series E
preferred stock to PCCW which will convert into 3,004,363 shares of our common
stock upon the closing of this offering.

   Sony Corporation

   We entered into an investment relationship with Sony Corporation of America
in October 1999. Sony's Vice President of Interactive Services has joined our
advisory board and has assisted in sales introductions and promoting technical
discussion with Sony regarding industry issues such as digital rights
management support, encryption, distribution and hosting methodologies.

   We sold 335,570 shares of our series D preferred stock to Sony for an
aggregate purchase price of approximately $2.0 million in October 1999 which
will convert into 1,386,239 shares of our common stock upon the closing of
this offering.

Sales and Marketing

   We primarily sell our services through our direct sales force. We are
currently focusing our sales efforts on the world's leading media and
entertainment companies which have launched or which we believe will launch
broadband multimedia initiatives. As of March 31, 2000, we had 30 employees in
our sales force devoted to developing relationships with content providers as
well as ISPs. We compensate our sales force with salary and commissions based
primarily on increasing traffic from existing customers as well as adding new
customers. Over the next few years we intend to significantly increase the
size of our sales force and expect to increase our expenditures on sales and
marketing efforts in the next twelve months. Our expenditures on sales and
marketing over the next 12 months are highly uncertain and will depend upon
various factors that are difficult to predict, including the number of sales
and marketing people that we are able to attract and the level of investment
that we determine we will need to market our brand over the next 12 months.

   In addition to our direct sales efforts, we are developing a network of
partners which include hosting companies, streaming services companies and
Internet service providers. Our partners will resell our full range of
services beyond our immediate target market.

   Our technical consulting group, composed of ten systems engineers and six
program managers, supports our sales efforts by providing implementation
services for On-Stage streaming events as well as On-Air and Internet radio
and media on-demand services.

   Our marketing strategy is to build a brand associated with high-fidelity
streaming media delivery. To support this objective, we have been engaged in a
direct marketing campaign that includes a presence at key trade shows,
speaking engagements at industry forums and iBEAM sponsored events and
seminars. We have also undertaken an advertising campaign aimed at our target
content provider customers. The advertising campaign consists of a mixture of
traditional media as well as Internet based advertising.

                                      48

Patents and Proprietary Rights

   Our success and ability to compete are dependent on our ability to develop
and maintain the proprietary aspects of our technology and operate without
infringing on the proprietary rights of others. We rely on a combination of
patent, trademark, trade secret and copyright laws and contractual
restrictions to protect the proprietary aspects of our technology. These legal
protections afford only limited protection for our technology. We have filed
eight patent applications and intend to file an additional ten patent
applications in the near future. These patent applications relate to our
streaming platform standard, content management, distribution capabilities and
subscriber management.

   We seek to limit disclosure of our intellectual property by requiring
employees and consultants with access to our proprietary information to
execute confidentiality agreements with us and by restricting access to our
source code. Due to rapid technological change, we believe that factors such
as the technological and creative skills of our personnel, new product
developments and enhancements to existing products are more important than the
various legal protections of our technology to establishing and maintaining a
technology leadership position.

   Despite our efforts to protect our proprietary rights, unauthorized parties
may attempt to copy aspects of our products or to obtain and use information
that we regard as proprietary. The laws of many countries do not protect our
proprietary rights to as great an extent as do the laws of the United States.
Litigation may be necessary in the future to enforce our intellectual property
rights, to protect our trade secrets, to determine the validity and scope of
the proprietary rights of others or to defend against claims of infringement
or invalidity. Any such resulting litigation could result in substantial costs
and diversion of resources and could have a material adverse effect on our
business, operating results and financial condition. There can be no assurance
that our means of protecting our proprietary rights will be adequate or that
our competitors will not independently develop similar technology. Any failure
by us to meaningfully protect our property could have a material adverse
effect on our business, operating results and financial condition.

   From time to time, third parties might claim infringement by us with
respect to our current or future products. These claims and any resulting
lawsuit, if successful, could subject us to significant liability for damages
and invalidate our proprietary rights. Any litigation or claims, whether or
not valid, could result in substantial costs and diversion of resources. In
January 2000, we received a letter from a competitor which suggested that we
review patents to which this company claims rights. These patents purport to
cover "a system and method for delivery of video and data over a computer
network." We have conducted an investigation with respect to such patents.
Based on our investigation, we believe that we do not infringe any claims of
these patents. However, there can be no assurance that the competitor will
agree with our conclusion or not pursue a claim or litigation against us. If
this competitor does pursue a claim against us, we intend to vigorously defend
against any such claim. However, a claim, if successful, could subject us to
significant liability for damages and invalidate our propriety rights.

   Any potential intellectual property litigation also could force us to do
one or more of the following:

  .  cease selling, incorporating or using products or services that
     incorporate the infringed intellectual property;

  .  obtain from the holder of the infringed intellectual property right a
     license to sell or use the relevant technology, which license may not be
     available on acceptable terms, if at all; or

  .  redesign those products or services that incorporate the disputed
     technology.

   We may in the future initiate claims or litigation against third parties
for infringement of our proprietary rights or to determine the scope and
validity of our proprietary rights or the proprietary rights of competitors.
These claims could result in costly litigation and the diversion of our
technical and management personnel. As a result, our operating results could
suffer and our financial condition could be harmed.

Competition

   The market for Internet broadcasting services is new, highly competitive,
and rapidly evolving. We expect competition to increase both from existing
competitors and new market entrants for various components of our service.
Unlike many of our competitors, we regard ourselves as the only Internet
broadcast network that combines satellite and land-line broadcasting of
streaming media as our primary business mission.

   Our competitors primarily come from five market segments:

  .  Internet content distribution networks that accelerate delivery of web
     pages, such as Akamai, Enron Communications and Digital Island;

  .  Internet webcasting companies that deliver streaming media through land-
     line networks, such as InterVu, which was recently acquired by Akamai;

  .  Internet software vendors that reduce that cost of delivery of content
     to users by storing content closer to the end user, such as Inktomi;

  .  Internet production and event services companies, such as Broadcast.com
     and Network24 Communications, which was acquired by Akamai; and

  .  Satellite companies that deliver streaming video through satellite
     networks, such PanAmSat and Cidera.

   We compete on price and quality of delivery, customer service, and network
features. We believe we currently have several primary competitive advantages,
including the quality of our network architecture, our proprietary technology
and our early entrance into the market for Internet broadcast services.
However, our competitors may be able to respond more quickly than we can to new
or emerging technologies and changes in customer requirements. Some of our
competitors may bundle their services with Internet related products or
services from Internet device vendors or Internet service providers. These
bundling relationships may inhibit our ability to sell service to Internet
content providers or to deploy servers at Internet service providers.

   Increased competition could result in price reductions, fewer customer
orders, reduced gross margins or loss of market share. Any of these conditions
could materially and adversely affect our business, financial condition, and
operational results.

Facilities

   Our headquarters are currently located in approximately 58,000 square feet
of leased office space in Sunnyvale, California. We recently obtained an
additional 22,000 square feet of office space near our headquarters.

   We are building a network operations center in our headquarters which began
operations in April 2000.

   Webcasts.com's principal offices are in Oklahama City, Oklahoma and Phoenix,
Arizona with sales offices in various U.S. cities.

Employees

   As of March 31, 2000, we had a total of 277 employees. We have never had a
work stoppage and no personnel are represented under collective bargaining
agreements. We consider our employee relations to be good.

   We have rapidly increased our employee base and need to continue to hire
additional personnel. We believe that our future success will depend upon our
continued ability to attract, integrate, retain, train and motivate highly
qualified personnel and upon the continued service of our senior management and
key personnel. Competition for qualified personnel is intense, particularly in
the Silicon Valley area, where our headquarters is located. There can be no
assurance that we will successfully attract, integrate, retain, train and
motivate a sufficient number of qualified personnel to conduct our business in
the future.

Development of our Business

   We believe that the net proceeds of this offering, together with our
available funds, will be sufficient to meet our anticipated needs for working
capital and capital expenditures for the next 12 to 18 months. We expect to
spend at least $40.0 million in 2000 for capital expenditures, $26.0 million
of which was incurred in the first quarter. The purpose of these capital
expenditures is to increase the number of users the network can support at the
edge of the Internet and relates primarily to our investment in edge servers,
hosting centers and our network operations center. In addition, we expect to
make additional expenditures to fund our sales and marketing and engineering
and development efforts in 2000. Our sales and marketing expenses are related
to our efforts to build up our sales force and build our brand name in order
to increase our customer base. Engineering and development expenses will be
related to developing value added services such as advertisement insertion
capabilities. The amount we spend for these purposes will depend on various
factors that are difficult to predict, including the level of competition we
will experience and the availability for hire of qualified sales, marketing
and engineering personnel.

Legal Proceedings

   On February 3, 2000, Gerald F. Chew filed a lawsuit in California state
court, County of Santa Clara, against us and one of our founders alleging
breach of contract and other claims entitled Gerald F. Chew v. iBEAM
Broadcasting, Inc. et al., No. CV 787599. Mr. Chew claims that he was one of
our founders and that we and one of our founders breached their promise to him
to issue founder's stock in exchange for his services. Mr. Chew alleges
damages of at least $10.0 million and seeks a determination from the Court
that he is entitled to an unspecified number of shares of our capital stock.
Mr. Chew's complaint is not clear whether his claims for such relief are
cumulative or in the alternative. In subsequent filings with the Court, Mr.
Chew has claimed entitlement to the same number of founders shares as received
by Mr. Wilmot. We intend to defend this action vigorously, however, litigation
is inherently uncertain and we may not prevail against Mr. Chew. Should Mr.
Chew prevail on his lawsuit, we could be required to issue stock to Mr. Chew
on the same terms as those granted to our founders and recognize an expense in
connection with such issuance, which could have a material adverse effect on
our results of operations. In addition, any such issuance would be dilutive to
existing stockholders.

   On April 20, 2000, InterVu, Inc. filed a lawsuit in California state court,
County of Santa Clara, against us and three of our employees entitled InterVu,
Inc. v. iBEAM Broadcasting et al., No. CV 89308. The complaint alleges claims
for misappropriation of trade secrets and inevitable disclosure and breach of
contract and seeks a temporary restraining order, a preliminary injunction and
damages. The complaint is based on the hiring of three former InterVu
employees by iBEAM. On April 25, 2000, the Court denied InterVu's application
for a temporary restraining order and set a hearing for InterVu's motion for a
permanent injunction for May 23, 2000. We intend to defend this action
vigorously, however, litigation is inherently uncertain and we may not prevail
against InterVu. Should InterVu prevail in its lawsuit, the three employees
who are the subject of this action would not be permitted to continue their
employment at iBEAM. InterVu also seeks damages of an unspecified amount, as
well as punitive damages.

   On April 20, 2000, Akamai Technologies, Inc. filed a lawsuit against us in
the Commonwealth of Massachusetts, Middlesex, Superior Court entitled Akamai
Technologies, Inc. v. iBEAM Broadcasting Corporation, 00-1944 alleging claims
for breach of contract and unauthorized acquisition of Akamai's confidential
information and trade secrets, among other claims. Akamai seeks injunctive
relief enjoining us from continuing the employment of one of its former
employees who is also the subject of the InterVu v. iBEAM case described
above. Akamai also seeks unspecified damages, as well as punitive damages. On
May 2, 2000, the court denied Akamai's request for injunctive relief
preventing us from continuing the employment of the employee in question and
from recruiting or soliciting any employee of Akamai. However, the court did
enjoin us for disclosing or using any of Akamai's trade secrets and directed
iBEAM to return to Akamai any confidential information or trade secrets. We
will continue to vigorously defend our company in this action, however,
litigation is inherently uncertain and we may not prevail against Akamai.
Should Akamai prevail in its lawsuit, the employee who is the subject of this
action would not be permitted to continue employment with us.

   The classification of directors has the effect of making it more difficult
to change the composition of the board of directors. See "Description of
Capital Stock--Delaware Law and Certain Provisions of Our Certificate of
Incorporation and Bylaws."

   Our board of directors appoints our executive officers on an annual basis
to serve until their successors have been elected and qualified. There are no
family relationships among any of our directors or officers.

Voting Agreement for Directors

   Under the terms of a voting agreement between us and the stockholders that
purchased shares of our preferred stock prior to the completion of this
offering, holders of our series A preferred and series B preferred had an
agreement to vote their shares at the election of directors in favor of a
director nominated by Crosspoint Venture Partners and Accel Partners. Mr.
Shapero is the nominee of Crosspoint Venture Partners and was elected to our
board of Directors as a result. Mr. Wagner is a nominee of Accel Partners and
was elected to our board of Directors as a result. This agreement terminates
with respect to these provisions upon the closing of our initial public
offering.

Board Committees

   Our Board of Directors has an Audit Committee and a Compensation Committee.
The Audit Committee of the Board of Directors consists of Messrs. Shapero,
Wagner and Baker. The Audit Committee reviews our financial statements and
accounting practices and makes recommendations to our Board of Directors
regarding the selection of independent auditors.

   The Compensation Committee of the Board of Directors consists of Messrs.
Shapero and Wagner. The Compensation Committee makes recommendations to the
Board of Directors concerning salaries and incentive compensation for our
officers and employees and administers our employee benefit plans.

Director Compensation

   We do not currently compensate our directors in cash for their service as
members of the board of directors, although directors are reimbursed for
reasonable expenses incurred in attending board or committee meetings. Our
officers are appointed by the board of directors and serve at its discretion.
We have granted options to purchase shares of our common stock to some of our
non-employee directors. In September 1999, we granted Mr. Seegal an option to
purchase 247,860 shares of common stock at an exercise price of $0.145 per
share. This option was granted under our 1998 Stock Plan. Of these shares,
214,812 shares of common stock subject to options vest over a four year period
with 25% of the shares subject to option vesting 12 months from the date of
grant and the remaining shares vesting ratably each month after that date so
long as Mr. Seegal continues to serve as our director. The remaining 33,048
shares subject to option vest over one year with 25% of the shares vesting at
the end each four month period from the date of grant so long as Mr. Seegal
continues to serve as our director.

   In July 1998, we granted Mr. Desnoes an option to purchase 111,537 shares
of common stock at an exercise price of $0.040 per share. This option was
granted under our 1998 Stock Plan. The shares underlying this option were
immediately vested.

   In January 2000, we granted Mr. Baker an option to purchase 82,620 shares
of common stock at an exercise price of $4.84 per share. These options were
granted under our 1998 Stock Plan. The shares underlying the option vests in
equal monthly installments over four years.

   Our 2000 Director Option Plan provides for the automatic grant of non-
statutory stock options to purchase 82,620 shares of common stock to non-
employee directors who join us after this offering. For further information
regarding the provisions of the 2000 Director Option Plan, see "--Employee and
Director Benefit Plans."

Limitations on Directors' Liability and Indemnification

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

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

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

  . Unlawful payments of dividends or unlawful stock repurchases or
    redemptions; or

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

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

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

   We have entered into agreements to indemnify our directors and executive
officers, in addition to the indemnification provided for in our bylaws. These
agreements provide, among other things, for indemnification for judgments,
fines, settlement amounts and expenses, including attorneys' fees incurred by
director, or executive officer in any action or proceeding, including any
action by or in our right, arising out of the person's services as a director
or executive officer, any of our subsidiaries or any other company or
enterprise to which the person provides services at our request. We believe
that these provisions and agreements are necessary to attract and retain
qualified persons as directors and executive officers.

                                      57
<PAGE>

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

Compensation Committee Interlocks and Insider Participation

   Our compensation committee currently consists of Messrs. Wagner and
Shapero. In January 1999, Mr. Desnoes, our President and Chief Executive
Officer, resigned from the compensation committee upon being appointed an
executive officer. Other than Mr. Desnoes, none of the members of our
compensation committee is currently or has been, at any time since the time of
our formation, one of our officers or employees. None of our executive
officers currently serves, or in the past has served, as a member of the board
of directors or compensation committee of any entity that has one or more
executive officers serving on our board or compensation committee. Mr. Wagner
is a general partner of Accel Partners, a holder of approximately 17.8% of our
outstanding stock that has purchased shares of our series B preferred stock,
series C preferred stock and series D preferred stock. Mr. Shapero is a
general partner of Crosspoint Venture Partners, a holder of approximately
18.9% of our outstanding stock that has purchased shares of our series A
preferred stock, series B preferred stock, series C preferred stock and
series D preferred stock. See "Certain Relationships and Related
Transactions."

Option Grants During Year Ended December 31, 1999

   The following table sets forth certain information for the year ended
December 31, 1999 with respect to grants of stock options to each of the named
executive officers. All options granted by us in 1999 were granted under our
1998 Stock Plan. These options have a term of 10 years. These options are
immediately exercisable in full at the date of grant, but shares purchased on
exercise of unvested options are subject to a repurchase right in our favor
that entitles us to repurchase unvested shares at their original exercise
price on termination of the employee's service with us. Unless otherwise
indicated, the repurchase right lapses as to 25% of the shares on the first
anniversary of the grant date and the balance over the next three years. See
"--Employee and Director Benefit Plans" for a description of the material
terms of these options.

   We granted options to purchase common stock and issued shares of common
stock pursuant to restricted stock purchase agreements equal to a total of
15,061,982 shares during 1999. Potential realizable values are net of exercise
price before taxes, and are based on the assumption that our common stock
appreciates at the annual rate shown, compounded annually, from the date of
grant until the expiration of the ten-year term. These numbers are calculated
based on SEC requirements and do not reflect our projection or estimate of
future stock price growth.

stock options during the fiscal year ended December 31, 1999 and unexercised
options held as of December 31, 1999 by each of the named executive officers.
The value realized is based on the reassessed fair market value of the
underlying securities as of the date of exercise, minus the per share exercise
price, multiplied by the number of shares underlying the option. The value of
unexercised in-the-money options are based on a value of $5.81 per share, the

Employment and Severance Agreements

   Peter Desnoes. In January 1999, we entered into a written employment
agreement with Mr. Desnoes. The agreement provides that Mr. Desnoes is
entitled to receive an annual salary of $300,000 and a bonus of $200,000, to
be paid based on the achievement of performance-based milestones. We also
agreed to provide Mr. Desnoes with compensation in the form of a grant of an
option to purchase 1,982,880 shares of common stock at an exercise price of
$0.040 per share, which vests over a four year period. The agreement also
provides that Mr. Desnoes is entitled to purchase up to 80,000 shares of our
Series C preferred stock on the same terms as the other investors. Mr. Desnoes
purchased these shares on February 3, 1999. In addition, we agreed to pay
expenses related to his relocation to California. See "Executive Compensation"
and "Certain Relationships and Related Transactions."

   The agreement provides that either we or Mr. Desnoes can terminate the
employment relationship for any reason with 14 days notice. The agreement
further provides that if Mr. Desnoes is terminated other than for cause, he

earliest of (i) 12 months from the date of his termination, (ii) the
expiration of his continuation coverage under COBRA and (iii) the date Mr.
Desnoes receives health insurance coverage in connection with new employment.

   In the event of a change of control, Mr. Desnoes will agree to continue

months if he is requested to do so. Upon the completion of this period, or if
Mr. Desnoes is not requested to remain with us or our successor, Mr. Desnoes
is entitled to receive six months salary and bonus and the options he has been
granted will vest as if he had performed an additional six months of service.
In the event that Mr. Desnoes is requested to remain with us or our successor
upon a change a control and he declines such request then Mr. Desnoes will not
be entitled to receive any additional compensation or vesting, unless his
refusal to continue service is in effect an involuntary termination, in which
case he will receive the benefits described in the preceding paragraph.

   Chris Dier. In November 1998, Chris Dier accepted our offer of employment.
The offer letter provides that Mr. Dier will receive an annual salary of
$180,000 and up to an additional $20,000 bonus each year based upon the
successful attainment of mutually agreed upon performance goals. The offer

   In September 1999, we entered into a Settlement Agreement and Mutual
Release with Michael Bowles in connection with his departure from our company.
We paid Mr. Bowles all salary and unused vacation through his employment end
date. In connection with Mr. Bowles' departure, the repurchase right with
respect to his shares of common stock lapsed. In addition, we and Mr. Bowles
agreed to a mutual release.

Employee and Director Benefit Plans

   1998 Stock Plan

   Our 1998 Stock Plan was adopted by our board of directors in March 1998,
and our stockholders initially approved the plan in April 1998. Our 1998 Stock
Plan provides for the grant of incentive stock options to our employees, and
for the grant of nonstatutory stock options and stock purchase rights to our
employees, directors and consultants.

   As of March 31, 2000, there were outstanding options to purchase 11,816,815
shares of common stock and 4,069,804 shares were available for future grant.
As of the date of this prospectus, we will not grant any additional stock
options under our 1998 stock plan. Instead we will grant options under our
2000 Stock Plan.

   The 1998 Stock Plan provides that in the event of a change in control, each
outstanding option shall be accelerated and become fully vested and
exercisable if such option is not assumed or substituted for by the successor
corporation.

   2000 Stock Plan

   Our 2000 Stock Plan was adopted by our board of directors in January 2000,
and approved by our stockholders in April 2000. An amendment to the plan is
expected to be approved by the board of directors and our stockholders in May
2000. This plan provides for the grant of incentive stock options to employees
and nonstatutory stock options and stock purchase rights to employees,
directors and consultants.

   As of March 2000, a total of 9,639,000 shares of common stock were reserved
for issuance pursuant to the 2000 Stock Plan. No options have yet been issued
pursuant to the 2000 Stock Plan. The number of shares reserved for issuance
under our 2000 Stock Plan will increase annually on January 1st of each
calendar year, effective beginning in 2001, equal to the lesser of:

  .  5% of the outstanding shares of common stock on the first day of the
     year,

  .  10,000,000 shares, or

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


                                      62
<PAGE>

   Our board of directors or a committee of our board administers the 2000
Stock Plan. The committee may consist of two or more "outside directors" to
satisfy certain tax and securities requirements. The administrator has the
power to determine the terms of the options or stock purchase rights granted,
including the exercise price, the number of shares subject to each option or
stock purchase right, the exercisability of the options, the vesting schedule
of the options and the form of consideration payable upon exercise. The
administrator determines the exercise price of options granted under our stock
option plan, but with respect to incentive stock options, the exercise price
must at least be equal to the fair market value of our common stock on the
date of grant. Additionally, the term of an incentive stock option may not
exceed ten years. The administrator determines the term of all other options.
No optionee may be granted an option to purchase more than 1,377,000 shares in
any fiscal year. In connection with his or her initial service, an optionee
may be granted an additional option to purchase up to 2,754,000 shares of our
common stock.

   After termination of one of our employees, directors or consultants, he or
she may exercise his or her option for the period of time stated in the option
agreement to the extent that shares have vested. If termination is due to
death or disability, the option will generally remain exercisable for 12
months following such termination. In all other cases, the option will
generally remain exercisable for three months. However, an option may never be
exercised later than the expiration of its term. The administrator determines
the exercise price of stock purchase rights granted under our 2000 Stock Plan.
Unless the administrator determines otherwise, the restricted stock purchase
agreement will grant us a repurchase option that we may exercise upon the
voluntary or involuntary termination of the purchaser's service with us for
any reason (including death or disability). The purchase price for shares we
repurchase will generally be the original price paid by the purchaser. The
administrator determines the rate at which our repurchase option will lapse.
Our stock option plan generally does not allow for the transfer of options or
stock purchase rights and only the optionee may exercise an option and stock
purchase right during his or her lifetime.

   Our 2000 Stock Plan provides that in the event of our merger with or into
another corporation or a sale of substantially all of our assets, the
successor corporation will assume or substitute for each option or stock
purchase right. If the outstanding options or stock purchase rights are not
assumed or substituted for, all outstanding options and stock purchase rights
will become fully vested and exercisable prior to the merger or sale of
assets.

   Our 2000 Stock Plan will automatically terminate in 2010, unless we
terminate it sooner. In addition, our board of directors has the authority to
amend, suspend or terminate the stock option plan provided it does not
adversely affect any option previously granted under our stock option plan.

2000 Employee Stock Purchase Plan

   Concurrently with this offering, we intend to establish an employee stock
purchase plan. A total of 1,500,000 shares of our common stock will be made
available for sale. In addition, our plan provides for annual increases in the
number of shares available for issuance under the purchase plan on January 1st
of each year, beginning in 2001, equal to the lesser of 2% of the outstanding
shares of our common stock on the first day of the calendar year, 3,000,000
shares, or such other lesser amount as may be determined by our board of
directors. Our board of directors or a committee of our board administers the
plan. Our board of directors or its committee has full and exclusive authority
to interpret the terms of the plan and determine eligibility. All of our
employees are eligible to participate if they are customarily employed by us
or any participating subsidiary for at least 20 hours per week and more than
five months in any calendar year. However, an employee may not be granted an
option to purchase stock under the plan if such employee:

  .  immediately after grant owns stock possessing 5% or more of the total
     combined voting power or value of all classes of our capital stock, or

  .  whose rights to purchase stock under all of our employee stock purchase
     plans accrues at a rate that exceeds $25,000 worth of stock for each
     calendar year.


                                      63
<PAGE>


   Our plan is intended to qualify for preferential tax treatment and contains
consecutive, overlapping 24-month offering periods. Each offering period
includes four six-month purchase periods. The offering periods generally start
on the first trading day on or after February 1 and August 1 of each year,
except for the first such offering period which will commence on the first
trading day on or after the effective date of this offering and will end on
the last trading day on or before January 31, 2001.

   The plan permits participants to purchase common stock through payroll
deductions of up to 15% of their eligible compensation which includes a
participant's base straight time gross earnings, commissions and bonuses but
excluding all other compensation paid to our employees. A participant may
purchase no more than 10,000 shares during any six-month purchase period.

   Amounts deducted and accumulated by the participant are used to purchase
shares of our common stock at the end of each six-month purchase period. The
price is 85% of the lower of the fair market value of our common stock at the
beginning of an offering period or after a purchase period ends. If the fair
market value at the end of a purchase period is less than the fair market
value at the beginning of the offering period, participants will be withdrawn
from the current offering period following their purchase of shares on the
purchase date and will be automatically re-enrolled in a new offering period.
Participants may end their participation at any time during an offering
period, and will be paid their payroll deductions to date. Participation ends
automatically upon termination of employment with us.

   A participant may not transfer rights granted under our employee stock
purchase plan other than by will, the laws of descent and distribution or as
otherwise provided under the plan.

   In the event of our merger with or into another corporation or a sale of
all or substantially all of our assets, a successor corporation may assume or
substitute each outstanding option. If the successor corporation refuses to
assume or substitute for the outstanding options, the offering period then in
progress will be shortened, and a new exercise date will be set.

   Our plan will terminate in 2010. However, our board of directors has the
authority to amend or terminate our plan, except that, subject to certain
exceptions described in the plan, no such action may adversely affect any
outstanding rights to purchase stock under our plan.

2000 Director Option Plan

   Our board of directors adopted the 2000 Director Option Plan in January
2000 and the plan was approved by our stockholders in April 2000. As of April
2000, a total of 688,500 shares were reserved for issuance under the Director
Plan, none of which were subject to outstanding options as of this date. The
number of shares reserved for issuance under our Director Plan will increase
annually on January 1st of each calendar year, effective beginning in 2001, by
an increase equal to that number of shares granted pursuant to options under
the Director Plan in the prior fiscal year or a lesser amount determined by
the board of directors.

   All grants of options to our non-employee directors under the Director Plan
are automatic. We will grant each non-employee director an option to purchase
82,620 shares upon the date when such person first becomes a non-employee
director (except for those directors who became non-employee directors by
ceasing to be employee directors).

   All options granted under our Director Plan have a term of ten years and an
exercise price equal to fair market value on the date of grant. Each option
vests and becomes exercisable as to 1/48th of the shares subject to the option
on each monthly anniversary of the date of grant, provided the non-employee
director remains a director on such dates. If a non-employee director's status
as a director terminates due to death or disability, the option will remain
exercisable for 12 months. In all other cases where a director's status is
terminated, the option will remain exercisable for a period of six months.
However, an option may never be exercised later than the expiration of its
term. A non-employee director may not transfer options granted under our
Director Plan other than by will or the laws of descent and distribution. Only
the non-employee director may exercise the option during his or her lifetime.

                                      64
<PAGE>


   In the event of our merger with or into another corporation or a sale of
substantially all of our assets, the successor corporation will assume or
substitute each option. If such assumption or substitution occurs, the options
will continue to be exercisable according to the same terms as before the
merger or sale of assets. Following such assumption or substitution, if a non-
employee director is terminated other than by voluntary resignation, the
option will become fully exercisable and generally will remain exercisable for
a period of six months. If the outstanding options are not assumed or
substituted for, our board of directors will notify each non-employee director
that he or she has the right to exercise the option as to all shares subject
to the option for a period of 180 days following the date of the notice. The
option will terminate upon the expiration of the 180-day period.

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

401(k) Plan

   Our employee savings and retirement plan is qualified under Section 401 of
the Internal Revenue Code. Our employees may elect to reduce their current
compensation by up to the statutorily prescribed annual limit and have the
amount of such reduction contributed to the 401(k) plan. We may make matching
or additional contributions to the 401(k) plan in amounts to be determined
annually by our board of directors.

   Series D Warrant. On October 14, 1999, we granted a warrant to Microsoft to
purchase 218,120 shares of our series D preferred stock at an exercise price
of $5.96 per share. By virtue of the fact that at the completion of this
offering each share of series D preferred stock will convert into 4.131 shares
of common stock, at the completion of this offering, the Microsoft warrant
will be exercisable for 901,053 shares of common stock at $1.44 per share.

   Common Stock. On March 23, 1998, we sold 7,636,669 shares of common stock
at a per share price of $.00024 to our three founders. Robert Wilmot, one of
our founders, is currently serving as one of our directors. The Wilmot Living
Trust, for which Mr. Wilmott and his spouse serve as trustees, purchased
2,743,190 shares of common stock. Of these shares, 75% are subject to our
right of repurchase which lapses as to 1.5625% of the shares after each month
Mr. Wilmot continues to serve as our employee or consultant. In connection
with the formation of our company, Mr. Wilmot entered into a consulting
agreement pursuant to which he agreed to spend at least one day a week
providing certain business development services as requested from time to time
by us.

   Michael Bowles, another of our founders and our former Chief Executive
Officer and director, purchased 4,114,785 shares of common stock. Of these
shares, 75% were subject to our right of repurchase which lapsed as to 1.5625%
of the shares after each month. Mr. Bowles continued to serve as our employee
or consultant. In connection with Mr. Bowles' departure from our company in
September 1999, our repurchase right lapsed with respect to Mr. Bowles' shares
of common stock. See "--Employment Agreements."

   Option Grants to Certain Directors. In September 1999, we granted Mr.
Seegal options to purchase 247,860 shares of common stock at an exercise price
of $0.145 per share. These options were granted under our 1998 Stock Plan. Of
these, 214,812 shares of common stock subject to options vest over a four year
period with 25% of the shares subject to option vesting 12 months from the
date of grant and the remaining shares vesting ratably each month after that
date so long as Mr. Seegal continues to serve as our director. The remaining
33,048 shares subject to option vest over one year with 25% of the shares
vesting at the end of each four month period from the date of grant so long as
Mr. Seegal continues to serve as our director.

   In July 1998, we granted Mr. Desnoes an option to purchase 111,537 shares
of common stock at an exercise price of $0.040 per share. This option was
granted under our 1998 Stock Plan. The shares underlying this option were
immediately vested.

   In January 2000, we granted Mr. Baker an option to purchase 82,620 shares
of common stock at an exercise price of $4.84 per share. These options were
granted under our 1998 Stock Plan. The shares underlying the option vests in
equal monthly installments over four years.

   Consulting Agreement with Director. In January 2000, we entered into a
consulting agreement with Mr. Seegal, one of our directors, wherein Mr. Seegal
agreed to assist us in financing plans and strategies and perform such other
business and marketing services as may from time to time be reasonably
requested by us. To date, Mr. Seegal has been in regular contact with our
Chief Executive Officer and other of our officers advising on financing plans
and other strategic matters. In connection with this agreement, Mr. Seegal
purchased 908,820 shares of our common stock at a per share price of $4.84 for
an aggregate purchase price of $4,395,600, all of which are subject to our
right of repurchase which lapses with respect to 12.5% of the shares six
months from the date of the purchase and which lapses ratably with respect to
1/48 of the remaining shares each month thereafter. We loaned Mr. Seegal
$1,999,998 to apply to the purchase price for these shares. As of April 12,
2000, we and Mr. Seegal mutually agreed to terminate the consulting
arrangement. The parties terminated the arrangement effective May 8, 2000. We
have the right to repurchase the shares purchased by Mr. Seegal pursuant to
the consulting arrangement at cost until June 7, 2000. We intend to repurchase
the 908,820 shares of our common stock held by Mr. Seegal for $2,395,602 and
cancel the $1,999,998 of indebtedness owed to us by Mr. Seegal by June 7,
2000.

   Microsoft Relationship. We entered into a collaboration agreement with
Microsoft, effective as of September 20, 1999, to improve the delivery of
streaming media over the Internet. Under the agreement, Microsoft recommends
us as a service provider for the delivery of broadband streaming media and we
will engage in cooperative sales efforts to promote Windows Media Technology.
Additionally, for the term of the agreement we have agreed to provide six
months of our services to content providers chosen by Microsoft, provided that
the value of these services to all such content providers does not exceed
$200,000 in the aggregate. Our agreement with Microsoft will extend through
September 2002. Microsoft has agreed to pay us $500,000 through April 15,
2000, all of which Microsoft may use to purchase our services either for
itself or on behalf of other Internet content providers. Microsoft's
obligations under the agreement are conditioned upon the performance of our
obligations under the agreement and our meeting certain performance criteria
for our services. On June 21, 1999, we also entered into an agreement with
Microsoft providing that Microsoft pay us $200,000. In consideration for this
payment we agreed to provide up to an aggregate of $200,000 in services to
content providers designated by Microsoft. This agreement extends through June
30, 2000 unless terminated by either party. This agreement may be terminated
by either party upon material breach of the other.

   Agreement with Brewer Consulting. In connection with the hiring of David
Brewer, our Vice President of Operations, we agreed to purchase at least $2.0
million of services from Brewer Consulting Networks, a company controlled by
Mr. Brewer, beginning January 1, 2000 and ending December 31, 2001. Brewer
Consulting Networks provides us with consulting services related to the
installation of our network servers. Our obligation to purchase these services
from Brewer Consulting Networks is contingent on Mr. Brewer relinquishing
operational or ownership control of Brewer Consulting Networks. We paid Brewer
Consulting Networks an aggregate of $702,395 for services provided in 1999.

Indemnification

   We have entered into indemnification agreements with each of our directors
and officers. These indemnification agreements and our certificate of
incorporation and bylaws require us to indemnify our directors and officers to
the fullest extent permitted by Delaware law. See "Management--Limitations on
Directors' Liability and Indemnification."

Conflict of Interest Policy

   We believe that all transactions with affiliates described above were made
on terms no less favorable to us than could have been obtained from
unaffiliated third parties. Our policy is to require that a majority of the
independent and disinterested outside directors on our board of directors
approve all future transactions between us and our officers, directors,
principal stockholders and their affiliates. These transactions will continue
to be on terms no less favorable to us than we could obtain from unaffiliated
third parties.

                            PRINCIPAL STOCKHOLDERS

   The following table sets forth the beneficial ownership of our common stock
as of March 31, 2000 (assuming conversion of all outstanding shares of
preferred stock into common stock upon the closing of this offering and as
adjusted to reflect the sale of the shares offered by this prospectus) by:

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

  .  each of the named executives and each of our directors; and

  .  all of our officers and directors as a group.

   Percentage of ownership is based on 95,147,834 shares outstanding as of
March 31, 2000, assuming conversion of the preferred stock, and 106,147,834
shares outstanding after this offering and no exercise of the underwriters'
over-allotment options. Beneficial ownership is calculated based on SEC
requirements. All shares of the common stock subject to options currently
exercisable or exercisable within 60 days after March 31, 2000 are deemed to
be outstanding for the purpose of computing the percentage of ownership of the
person holding such options, but are not deemed to be outstanding for
computing the percentage of ownership of any other person. Unless otherwise
indicated below, each stockholder named in the table has sole voting and
investment power with respect to all shares beneficially owned, subject to
applicable community property laws. Unless otherwise indicated in the table,
the address of each individual listed in the table is iBEAM Broadcasting
Corporation, 645 Almanor Avenue, Suite 100, Sunnyvale, CA 94086.

                         DESCRIPTION OF CAPITAL STOCK

   Upon the closing of this offering, we will be authorized to issue
413,100,000 shares of common stock, $.0001 par value per share, and 10,000,000
shares of undesignated preferred stock, $.0001 par value per share. The
following description of our capital stock does not purport to be complete and
is subject to and qualified by our certificate of incorporation and bylaws,
which are included as exhibits to the registration statement of which this
prospectus forms a part, and by the provisions of applicable Delaware law.

Common Stock

   As of March 31, 2000, there were 95,147,834 shares of common stock
outstanding, assuming the conversion of all outstanding shares of preferred
stock into common stock, which were held of record by approximately 260
stockholders. This number includes:

 .  66,489,527 shares of common stock to be issued upon automatic conversion
    of all outstanding shares of our series A, B, C, D and E preferred stock
    upon completion of this offering;

 .  8,233,173 shares of our series F preferred stock issued in connection with
    the acquisition of webcasts.com and the conversion of those shares into
    the same number of shares of common stock;

 .  1,000,000 shares of our series G preferred stock to be issued to The Walt
    Disney Corporation for $10.0 million at a per share price equal to the
    price to the public in this offering and the conversion of these shares
    into the same number shares of common stock; and

 .  537,634 shares of our series H preferred stock to be issued to Excite@Home
    for $5.0 million at a per share price equal to the price to the public in
    this offering, less estimated underwriting commissions and discounts, and
    the conversion of these shares into the same number of shares of common
    stock.

   The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may
be applicable to any outstanding preferred stock, the holders of common stock
are entitled to receive ratably dividends, if any, as may be declared from
time to time by the board of directors out of funds legally available for that
purpose. See "Dividend Policy." In the event of our liquidation, dissolution
or winding up, the holders of common stock are entitled to share ratably in
all assets remaining after payment of liabilities, subject to prior
distribution rights of preferred stock, if any, then outstanding. The common
stock has no preemptive or conversion rights or other subscription rights.
There are no redemption or sinking fund provisions applicable to the common
stock. All outstanding shares of common stock are fully paid and
nonassessable, and the shares of common stock to be issued upon the closing of
this offering will be fully paid and nonassessable.

Preferred Stock

   The board of directors has the authority, without action by our
stockholders, to designate and issue preferred stock in one or more series and
to designate the rights, preferences and privileges of each series, any or all
of which may be greater than the rights of the common stock. The effect of the
issuance of any shares of preferred stock upon the rights of holders of the
common stock might include, among other things, restricting dividends on the
common stock, diluting the voting power of the common stock, impairing the
liquidation rights of the common stock and delaying or preventing a change in
control of iBEAM without further action by the stockholders. We have no
present plans to issue any shares of preferred stock.

Warrants

   On an as converted basis, as of March 31, 2000, there were warrants
outstanding to purchase a total of 1,949,987 shares of common stock. All of
these warrants will remain outstanding after the completion of this offering.
Of these, warrants to purchase 511,300 shares of common stock will expire
three years from the date of this prospectus unless earlier exercised, of
which 112,664 shares are exercisable at an exercise price of $0.40 per share,
268,246 shares are exercisable at an exercise price of $0.56 per share, 26,421
shares are exercisable at an exercise price of $1.14 per share and 103,969
shares are exercisable at an exercise price of $1.44 per share.

                                      71
<PAGE>

Another warrant to purchase 901,053 shares of common stock expires four years
from the completion of this offering unless earlier exercised and has an
exercise price of $1.44 per share. Another warrant to purchase 537,634 shares
of common stock expires four years from the closing of this offering unless
earlier exercised and has an exercise price of equal to the price to the
public in the offering, less estimated underwriting discounts and commissions.

Registration Rights

   After this offering, the holders of approximately 76,260,334 shares of
common stock and the holders of warrants to purchase approximately 1,438,687
shares of common stock will be entitled to rights with respect to the
registration of these shares under the Securities Act. These holders are
entitled to demand registration rights pursuant to which they may require us
on up to two occasions to file a registration statement under the Securities
Act at our expense. We are required to use all reasonable efforts to effect
this registration. These registration rights are subject to the right of the
underwriters of an offering to limit the number of shares included in such
registration. They are also subject to our right not to effect a requested
registration within 180 days following an offering of our securities pursuant
to a registration statement in connection with an underwritten public
offering, including this offering, or if we believe that a registration at
that time would be seriously detrimental to us. Additionally, if we propose to
register any of our securities under the Securities Act, either for our
account or the account of other security holders exercising registration
rights, these holders are entitled to notice of such registration and are
entitled to include some or all of their shares of common stock in the
registration. These registration rights are also subject to the right of the
underwriters of an offering to limit the number of shares included in the
registration. Further, holders may require us to file registration statements
on Form S-3 at our expense. These registration rights are subject to our right
not to effect a requested registration if it would be seriously detrimental to
us to file an S-3 registration statement at that time.

Delaware Law and Certain Provisions of Our Certificate of Incorporation and
Bylaws

   Certain provisions of Delaware law and our certificate of incorporation and
bylaws could make it more difficult to acquire us by means of a tender offer,
a proxy contest or otherwise and the removal of incumbent officers and
directors. These provisions, summarized below, are expected to discourage
certain types of coercive takeover practices and inadequate takeover bids and
to encourage persons seeking to acquire control of us to first negotiate with
us. We believe that the benefits of increased protection of our potential
ability to negotiate with the proponent of an unfriendly or unsolicited
proposal to acquire or restructure us outweigh the disadvantages of
discouraging takeover or acquisition proposals because, among other things,
negotiation of these proposals could result in an improvement of their terms.

   We are subject to Section 203 of the Delaware General Corporation Law, an
anti-takeover law. In general, Section 203 prohibits a publicly held Delaware
corporation from engaging in a "business combination" with an "interested
stockholder" for a period of three years following the date the person became
an interested stockholder, unless, with exceptions, the business combination
or the transaction in which the person became an interested stockholder is
approved in a prescribed manner. Generally, a business combination includes a
merger, asset or stock sale, or other transaction resulting in a financial
benefit to the interested stockholder. Generally, an interested stockholder is
a person who, together with affiliates and associates, owns, or within three
years prior to the determination of interested stockholder status, did own,
15% or more of a corporation's voting stock. The existence of this provision
would be expected to have an anti-takeover effect with respect to transactions
not approved in advance by the board of directors, including the
discouragement of attempts that might result in a premium over the market
price for the shares of common stock held by stockholders.

   Our certificate of incorporation and bylaws require that any action
required or permitted to be taken by our stockholders must be effected at a
duly called annual or special meeting of the stockholders and may not be
effected by a consent in writing. In addition, special meetings of our
stockholders may be called only by the board of directors or certain of our
officers. Our certificate of incorporation and bylaws also provide that,
beginning upon the closing of this offering, our board of directors will be
divided into three classes, with each

                                      72
<PAGE>

class serving staggered three-year terms. These provisions may have the effect
of deterring hostile takeovers or delaying changes in control or management of
iBEAM.

Agreement with Investors

   America Online, Pacific Century CyberWorks, Microsoft, Sony, Covad and
Exite@Home have each agreed not to acquire more than 15% of our voting stock
at any time before October 2004 without our permission. This standstill
agreement terminates under the following circumstances:

 .  we sell equity securities to another company with whom we have a strategic
    relationship, and such company does not enter into a similar standstill
    agreement;

 .  with respect to one of these investors, if another investor breaches the
    standstill agreement and the breach is not cured within ten days; or

 .  another company or group initiates a tender offer for 15% or more of our
    capital stock, acquires 15% of our capital stock, acquires all or
    substantially all of our assets, enters an agreement to acquire 15% or
    more of our capital stock, or solicits proxies in opposition to a proxy
    solicitation of iBEAM.

   In addition, these investors have agreed not to transfer shares of our
capital stock owned by them for a period of one year after the closing date of
this offering.

Voting Agreement

   Each of Pacific Century CyberWorks, America Online, Microsoft, Sony, Covad
and Liberty Media, which in the aggregate will own 15.9% of our common stock
upon the closing of this offering, have agreed to vote their securities as
directed by our board of directors, in any merger in which more than 50% of
our voting power is transferred or in a sale of substantially all of our
assets. This obligation lapses for each of these companies if and when it owns
less than 5% of our voting power.

Transfer Agent and Registrar

   The transfer agent and registrar for the common stock is Equiserve Trust
Company. The transfer agent's address is P.O. Box 2533, mail stop 4691, Jersey
City, NJ 07303, and its telephone number is (201) 222-5610.

                        SHARES ELIGIBLE FOR FUTURE SALE

   Immediately prior to this offering, there was no public market for our
common stock. Future sales of substantial amounts of common stock in the
public market could adversely affect the market price of our common stock.

   Upon completion of this offering, we will have outstanding 106,147,834
shares of common stock, assuming the issuance of 11,000,000 shares of common
stock offered by us and no exercise of options outstanding after March 31,
2000. Of the 11,000,000 shares sold in this offering, 9,800,000 shares will be
freely tradable without restriction or further registration under the
Securities Act, except for shares purchased by our affiliates, as defined
under the Securities Act. The Securities Act defines affiliates to be persons
that directly, or indirectly through one or more intermediaries, controls, or
is controlled by, or is under common control with, iBEAM. These persons
typically include our executive officers and directors. Shares purchased by
affiliates would be subject to the limitations and restrictions that are
described below.

   Of the remaining 96,347,834 shares of common stock, 95,147,834 shares were
issued and sold by us in reliance on exemptions from the registration
requirements of the Securities Act and 1,200,000 shares were issued in this
offering as part of our directed share program. All these shares will be
subject to lock-up agreements, described below, on the date of this
prospectus. Upon expiration of the lock-up agreements, 83,071,938 shares will
become eligible for sale pursuant to Rule 144(k), Rule 144, and Rule 701.
Thereafter, 13,275,876 shares will become eligible for sale pursuant to Rule
144.

</TABLE>

Rule 144

   In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this prospectus, a person who has beneficially owned shares of our
common stock for at least one year would be entitled to sell, within any
three-month period, a number of shares that does not exceed the greater of:

  . 1% of the number of shares of common stock then outstanding, which will
    equal approximately 1,061,478 shares immediately after this offering, or

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

   Sales under Rule 144 are also subject to other requirements regarding the
manner of sale, notice filing and the availability of current public
information about us.

Rule 144(k)

   Under Rule 144(k), a person who is not deemed to have been one of our
affiliates at any time during the three months preceding a sale, and who has
beneficially owned the shares proposed to be sold for at least two years,
including the holding period of any prior owner other than an affiliate, is
entitled to sell such shares without complying with the manner of sale, notice
filing, volume limitation or notice provisions of Rule 144. Therefore, unless
otherwise restricted, "144(k) shares" may be sold immediately upon the
completion of this offering.

Rule 701

   In general, under Rule 701, any of our employees, directors, officers,
consultants, or advisors who purchases shares from us in connection with a
compensatory stock or option plan or other written agreement before the

                                      74
<PAGE>

effective date of this offering is entitled to resell such shares 90 days
after the effective date of this offering in reliance on Rule 144, without
having to comply with the holding period requirements or other restrictions
contained in Rule 701.

   The Securities and Exchange Commission has indicated that Rule 701 will
apply to typical stock options granted by an issuer before it becomes subject
to the reporting requirements of the Securities Exchange Act, along with the
shares acquired upon exercise of such options, including exercises after the
date of this prospectus. Securities issued in reliance on Rule 701 are
restricted securities and, subject to the contractual restrictions described
above, beginning 90 days after the date of this prospectus, may be sold by
persons other than "affiliates," as defined in Rule 144, subject only to the
manner of sale provisions of Rule 144 and by "affiliates" under Rule 144
without compliance with its one-year minimum holding period requirement.

Registration Rights

   Beginning six months after the date of this offering, the holders of
approximately 76,260,334 shares of common stock and the holders of warrants to
purchase approximately 1,438,687 shares of common stock will be entitled to
certain rights with respect to the registration of these shares for sale in
the public market. See "Description of Capital Stock--Registration Rights."
Registration of these shares under the Securities Act would result in these
shares becoming freely tradeable in the public market without restriction.

Warrants

   As of March 31, 2000, there were a total of 1,949,987 shares of common
stock subject to outstanding warrants, all of which are subject to lock-up
agreements similar to those described below. These shares will become eligible
for sale on various date upon expiration or release of the 180-day lock-up
agreements.

Stock Options

   As of March 31, 2000, there were a total of 11,816,815 shares of common
stock subject to outstanding options under our 1998 Stock Plan, all of which
are subject to lock-up agreements similar to those described below.
Immediately after the completion of the offering, we intend to file
registration statements on Form S-8 under the Securities Act to register all
of the shares of common stock issued or reserved for future issuance under our
1998 Stock Plan, 2000 Stock Plan, 2000 Director Stock Option Plan, and 2000
Employee Stock Purchase Plan. After the effective dates of these registration
statements, shares purchased upon exercise of options granted under the 1998
Stock Plan, 2000 Stock Plan, 2000 Director Stock Plan and 2000 Employee Stock
Purchase Plan will be available for resale in the public market.

Lock-up Agreements

   All of our officers and directors and substantially all of our
stockholders, have agreed, subject to limited exceptions, not to offer,
pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase, lend or otherwise transfer or dispose of, directly or indirectly, or
enter into any swap or other arrangement that transfers to another, in whole
or in part, any of the economic consequences of ownership of any shares of
common stock or any securities convertible into or exercisable or exchangeable
for shares of common stock for a period ending 180 days after the date of this
prospectus, without the prior written consent of Morgan Stanley & Co.
Incorporated. In addition, the participants in the directed share program, as
described in the section entitled "Underwriters," will be subject to similar
lock-up restrictions.

   We have no agreement or understanding with Morgan Stanley & Co.
Incorporated for a waiver of these lock-up restrictions. However, Morgan
Stanley & Co. Incorporated may, in its discretion, release us or any of our
stockholders at any time, without notice, prior to the expiration of the lock-
up period. In some cases underwriters have agreed to waive lock-up
restrictions when a company's stock has performed well for a sustained period
of time in order to allow a follow-on offering of common stock. Any decision
by Morgan Stanley & Co. Incorporated to waive the lock-up restrictions would
depend on a number of factors, including market conditions, the performance of
our common stock in the market and our financial condition at that time. If
Morgan Stanley & Co. Incorporated were to waive the lock-up restrictions prior
to the expiration of the 180-day period, and our stockholders were to sell
additional shares of common stock to the public, the market price of our
common stock could decline.

</TABLE>

   The underwriters are offering the shares of common stock subject to their
acceptance of the shares from iBEAM and subject to prior sale. The
underwriting agreement provides that the obligations of the several
underwriters to pay for and accept delivery of the shares of common stock
offered by this prospectus are subject to the approval of certain legal
matters by their counsel and to certain other conditions. The underwriters are
obligated to take and pay for all of the shares of common stock offered by
this prospectus if any such shares are taken. However, the underwriters are
not required to take or pay for the shares covered by the underwriters' over-
allotment option described below.

   The underwriters initially propose to offer part of the shares of common
stock directly to the public at the public offering price listed on the cover
page of this prospectus and part to certain dealers at a price that represents
a concession not in excess of $     a share under the public offering price.
No underwriter will allow, and no dealer will reallow, a concession to other
underwriters or to dealers. After the initial offering of the shares of common
stock, the offering price and other selling terms may from time to time be
varied by the representatives.

   iBEAM has granted to the underwriters an option, exercisable for 30 days
from the date of this prospectus, to purchase up to an aggregate of 1,650,000
additional shares of common stock at the public offering price listed on the
cover page of this prospectus, less underwriting discounts and commissions.
The underwriters may exercise this option solely for the purpose of covering
overallotments, if any, made in connection with the offering of the shares of
common stock offered by this prospectus. To the extent the option is
exercised, each underwriter will become obligated, subject to certain
conditions, to purchase about the same percentage of the additional shares of
common stock as the number listed next to the underwriter's name in the
preceding table bears to the total number of shares of common stock listed
next to the names of all underwriters in the preceding table. If the
underwriters' option is exercised in full, the total price to the public would
be $    , the total underwriters' discounts and commissions would be $
and total proceeds to iBEAM would be $     .

   The underwriting discounts and commissions will be determined by
negotiations between iBEAM and the representatives and will be a percentage of
the offering price to the public. The primary factors to be considered in
determining the discounts and commissions will be the size of the offering,
the nature of the securities offered and the discounts and commissions charged
in comparable transactions. The estimated offering expenses payable by iBEAM,
in addition to the underwriting discounts and commissions, are approximately
$1,750,000, which includes legal, accounting and printing costs and various
other fees associated with registering and listing the common stock.

allotment option.

   The underwriters have informed iBEAM that they do not intend sales to
discretionary accounts to exceed 5% of the total number of shares of common
stock offered by them.

   Application has been made for quotation on the Nasdaq National Market under
the symbol "IBEM."

   Each of iBEAM and the directors, executive officers and certain other
stockholders of iBEAM has agreed that, without the prior written consent of
Morgan Stanley & Co. Incorporated on behalf of the underwriters, it will not,
during the period ending 180 days after the date of this prospectus:

  .  offer, pledge, sell, contract to sell, sell any option or contract to
     purchase, purchase any option or contract to sell, grant any option,
     right or warrant to purchase, lend or otherwise transfer or dispose of,
     directly or indirectly, any shares of common stock or any securities
     convertible into or exercisable or exchangeable for common stock; or

  .  enter into any swap or other arrangement that transfers to another, in
     whole or in part, any of the economic consequences of ownership of the
     common stock.

whether any transaction described above is to be settled by delivery of common
stock or such other securities, in cash or otherwise. The restrictions
described in this paragraph do not apply to:

  .  the sale of shares to the underwriters;

  .  the issuance by iBEAM of shares of common stock upon the exercise of an
     option or a warrant or the conversion of a security outstanding on the
     date of this prospectus of which the underwriters have been advised in
     writing; or

  .  transactions by any person other than iBEAM relating to shares of common
     stock or other securities acquired in open market transactions after the
     completion of the offering of the shares.

   In order to facilitate the offering of the common stock, the underwriters
may engage in transactions that stabilize, maintain or otherwise affect the
price of the common stock. Specifically, the underwriters may over-allot in
connection with the offering, creating a short position in the common stock
for their own account. In addition, to cover over-allotments or to stabilize
the price of the common stock, the underwriters may bid for, and purchase,
shares of common stock in the open market. Finally, the underwriting syndicate
may reclaim selling concessions allowed to an underwriter or a dealer for
distributing the common stock in the offering, if the syndicate repurchases
previously distributed common stock in transactions to cover syndicate short
positions, in stabilization transactions or otherwise. Any of these activities
may stabilize or maintain the market price of the common stock above
independent market levels. The underwriters are not required to engage in
these activities, and may end any of these activities at any time.

   iBEAM and the underwriters have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act.

   At the request of iBEAM, the underwriters have reserved for sale, at the
initial offering price, up to 1,200,000 shares offered hereby for directors,
officers, employees and business associates and related persons, such as
consultants and suppliers, of iBEAM. The shares of common stock available for
sale to the general public will be reduced to the extent such persons purchase
such reserved shares. Any reserved shares which are not so

                                      77
<PAGE>


purchased will be offered by the underwriters to the general public on the
same basis as the other shares offered hereby. Purchasers of these shares that
are not otherwise subject to the restrictions described above must represent
that they will not sell, transfer, assign, pledge or hypothecate these shares
for the period ending 180 days after the date of this prospectus.

   Morgan Stanley Dean Witter Online Inc., an affiliate of Morgan Stanley &
Co. Incorporated, will distribute shares of common stock over the Internet to
its eligible account holders. E*TRADE Securities, Inc. will also distribute
shares of common stock over the Internet to its customers. In connection with
these Internet distributions, each of these underwriters will provide for
offers and acceptances of offers to be made through e-mail and over the
Internet.

   Prior to this offering, there has been no public market for the common
stock. The initial public offering price will be determined by negotiations
between iBEAM and the representatives. The primary factors to be considered in
determining the initial public offering price will be the future prospects of
iBEAM and its industry in general, revenues, operating results and certain
other financial operating information of iBEAM in recent periods, and the
price-earnings ratios, price-revenues ratios, market prices of securities and
certain financial and operating information of companies engaged in activities
similar to those of iBEAM. The estimated initial public offering price range
set forth on the cover page of this preliminary prospectus is subject to
change as a result of market conditions and other factors.

   iBEAM sold an aggregate of 83,893 shares of Series D preferred stock to
J.P. Morgan Direct Venture Capital Institutional Investors LLC and J.P. Morgan
Direct Venture Capital Private Investors LLC in October 1999, each of which is
a fund of investors associated with J.P. Morgan Securities Inc., one of the
representatives in this offering.

To the Board of Directors and Stockholders of
 iBEAM Broadcasting Corporation

   In our opinion, the accompanying balance sheets and the related statements
of operations, of redeemable convertible preferred stock and stockholders'
deficit and of cash flows present fairly, in all material respects, the
financial position of iBEAM Broadcasting Corporation (a development stage
company) as of December 31, 1998 and 1999 and the results of its operations
and its cash flows for the period from March 20, 1998 (inception) to December
31, 1998, and for the year ended December 31, 1999, and for the period from
March 20, 1998 (inception) to December 31, 1999, in conformity with accounting
principles generally accepted in the United States. These financial statements
are the responsibility of the Company's management; our responsibility is to
express an opinion on these financial statements based on our audits. We
conducted our audits of these statements in accordance with auditing standards
generally accepted in the United States which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for the
opinion expressed above.

                         NOTES TO FINANCIAL STATEMENTS

1. The Company

   iBEAM Broadcasting Corporation (the "Company"), formerly Bowles, Inc., was
incorporated on March 20, 1998 in Delaware. iBEAM provides an Internet
broadcast network that enables content providers to broadcast content over the
Internet. The network uses point-to-multipoint satellite broadcasting of
Internet content to intelligent iBEAM servers located at the edge of the
Internet, which is the Internet access point closest to the end user.

   Prior to March 31, 2000 the Company was in the development stage, devoting
substantially all of its efforts to product development and raising capital
financing. The Company has funded its operating losses since inception through
capital lease obligations and the sale of equity securities. Management's
plans for funding operations include generating revenue while controlling
costs, the sale of equity securities and the utilization of equipment lease
lines (see Note 5). The Company's failure to sell its services or to raise
sufficient capital would unfavorably impact the Company.

2. Significant Accounting Policies

   Unaudited interim results

   The accompanying interim financial statements as of March 31, 2000 and for
the three-months ended March 31, 1999 and 2000 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 Company's financial position, results of operations and
cash flows as of March 31, 2000 and for the three months ended March 31, 1999
and 2000. The financial data and other information disclosed in these notes to
financial statements related to these periods are unaudited. The results for
the three months ended March 31, 2000 are not necessarily indicative of the
results to be expected for the year ending December 31, 2000.

   Use of estimates

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

   Stock split

   The Company's Board of Directors authorized a 3-for-1 stock split of the
Company's common stock in January 2000. In March 2000, the Company's Board of
Directors authorized a 1.377-for-1 stock split of the Company's common stock.
All common and per share information in these financial statements has been
retroactively adjusted to reflect these stock splits. As a result of these
splits, the conversion rate of Series A, B, C, and D redeemable convertible
preferred stock into common stock automatically adjusts from 1:1 to 1:4.131
and has been retroactively adjusted in these financial statements (see note
7). The Company issued Series E redeemable convertible preferred stock in
February 2000. The conversion rate of Series E redeemable convertible
preferred stock into common stock automatically adjusts from 1:1 to 1:1.377.

   Risks and uncertainties

   The Company is subject to all of the risks inherent in an early stage
company conducting electronic services over the Internet. These risks include,
but are not limited to, a limited operating history, limited management

resources, dependence upon consumer acceptance of the Internet and the
changing nature of the electronic broadcasting industry. The Company's
operating results may be materially affected by the foregoing factors.

   Cash, cash equivalents, restricted cash and investments

   The Company considers all highly liquid investments purchased with original
or remaining maturities of three months or less at the date of purchase to be
cash equivalents. Restricted cash of $107,000 consists of a certificate of
deposit held as collateral against the Company's corporate credit cards and is
included in other assets.

   The Company classifies all short-term investments as available-for-sale in
accordance with Statement of Financial Accounting Standards ("SFAS") No. 115,
"Accounting for Certain Investments in Debt and Equity Securities." The
Company's short-term investments are invested in high-grade corporate
securities and government bonds maturing approximately twelve months or less
from the date of purchase. At December 31, 1999, these investments are carried
at cost, which approximates fair value. Material unrealized gains or losses,
if any, are reported in stockholders' equity and included in other
comprehensive income. The cost of securities sold is based on the specific
identification method. For the year ended December 31, 1999, realized gains
and losses on available-for-sale securities were immaterial.

   Fair value of financial instruments

   The reported amounts of certain of the Company's financial instruments,
including cash and cash equivalents, short-term investments, accounts
receivable, accounts payable and accrued liabilities approximate fair value
due to their short maturities.

   Concentration of credit risk

   Cash and cash equivalents are deposited in large domestic financial
institutions that management believes are creditworthy. With respect to
accounts receivable, the Company's customer base is dispersed across many
geographic areas primarily within the United States. The Company performs
ongoing credit evaluations of its customers financial condition, generally
requires no collateral from its customers, and establishes allowances for bad
debt as warranted.

   Property and equipment

   Property and equipment are stated at cost. Depreciation is generally
computed using the straight-line method over the estimated useful lives of the
assets as follows:

<TABLE>
   <S>                                           <C>

                                                  the estimated useful life
</TABLE>

   Long-lived assets

   The Company evaluates the recoverability of its long-lived assets in
accordance with SFAS No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be Disposed of," which requires
recognition of impairment of long-lived assets in the event the net book value
of such assets exceeds the future undiscounted cash flows attributable to such
assets.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)


   Revenue recognition

   On-Air is a service that provides the customer the ability to transfer live
content 24 hours a day, 7 days a week. On-Air services are provided under
contracts that typically last for a period of three to twelve months. These
services are billed based upon either the peak capacity purchased, which is
expressed as the maximum volume that can be delivered per second, or upon
actual usage, which is the total amount of megabytes transferred in the month.
These contracts may also provide for minimum monthly fees. Revenue for these
services is recognized as the service is provided.

   On-Stage services are provided under contracts that typically relate to a
single event. These services are billed based upon the peak capacity purchased
which is the maximum megabits delivered per second per event, or upon actual
usage, which is the total amount of megabits transferred. These contracts may
also provide for minimum fees. Revenue for these services is recognized as the
service is provided.

   On-Demand is a service that allows the customer to store content on the
Company's network, which can then be accessed by end users at any time. This
service is provided under contracts that typically last for a period of three
to twelve months. There are two streams of revenue associated with this
service. Firstly, there is a fee for the amount of content stored, measured in
gigabytes per month. Secondly, there is a charge for the amount of content
delivered to end users which is billed based upon either the peak capacity
purchased, which is the maximum megabits delivered per second, or upon actual
usage, which is the total amount of megabytes transferred in the month. These
contracts may also provide for minimum monthly fees. Revenue for these
services is recognized as the service is provided.

   The Company has the ability to insert advertisements into the content
delivered in connection with the On-Air, On-Stage and On-Demand services.
Revenue from advertising is recognized over the period the advertisements are
delivered.

   Other services such as encoding, production, event management, acquisition
services, custom web integration with chat and e-commerce tools are generally
provided on a consulting basis on either hourly or fixed price billing over a
period of 30 days or less. Revenue for these services is recognized upon
completion of the services.

   The Company is required to share 15%-20% of the revenue generated from the
delivery of content from the On-Air, On-Stage and On-Demand services with
certain internet service providers. The Company records the revenue from On-
Air, On-Stage and On-Demand services gross because they act as the principal
in the transactions and are wholly responsible for the delivery of the
services. In addition, the Company bears the risk of loss for collection from
the customer. The Company records the revenue sharing amount as cost of
services.

   Cash payments received in advance of services provided are recorded as
deferred revenue.

   Engineering and development expense

   Engineering and development costs are expensed as incurred, except for
certain software development costs. In January 1999, the Company adopted
Statement of Position ("SOP") 98-1, which requires software development costs
associated with internal use software to be charged to operations until
certain capitalization criteria are met. For the year ended December 31, 1999,
software development costs of approximately $800,000 were capitalized and
included in property and equipment.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)


   Advertising expense

   Expenses related to advertising and promotion of products is charged to
sales and marketing expense as incurred. Advertising expense for the period
from March 20, 1998 (inception) to December 31, 1998 and for the year ended
December 31, 1999 was $23,000 and $2,621,000, respectively.

   Stock-based compensation expense

   The Company accounts for stock-based employee compensation arrangements in
accordance with provisions of Accounting Principles Board Opinion No. 25 ("APB
No. 25"), "Accounting for Stock Issued to Employees," and complies with the
disclosure provisions of SFAS No. 123, "Accounting for Stock-Based
Compensation." Under APB No. 25, compensation expense is based on the
difference, if any, on the date of grant, between the fair value of the
Company's shares and the exercise price of the option. Equity instruments
issued to nonemployees are accounted for in accordance with the provisions of
SFAS No. 123 and Emerging Issues Task Force ("EITF") 96-18.

   Comprehensive income (loss)

   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. There is no difference between net loss and
comprehensive loss.

   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 shares of common stock
outstanding during the period. The calculation of diluted net loss per share
excludes potential common shares if the effect is antidilutive. Potential
common shares are comprised of common stock subject to repurchase rights and
incremental shares of common and preferred stock issuable upon the exercise of
stock options or warrants and upon conversion of Series A, Series B, Series C
and Series D convertible preferred stock (collectively, "Preferred Stock").

   The following table sets forth the computation of basic and diluted net
loss per share for the periods indicated (in thousands, except per share
amounts):

   Pro forma net loss per share (unaudited)

   Pro forma net loss per share for the year ended December 31, 1999 and the
three months ended March 31, 2000 is computed using the weighted average
number of common shares outstanding, including the pro forma effects of the
automatic conversion of the Company's Preferred Stock into shares of common
stock effective upon the closing of the offering, as if such conversion
occurred on January 1, 1999 or at the date of original issuance, if later. The
resulting pro forma adjustment includes an increase in the weighted average
shares used to compute basic and diluted net loss per share of 38,709,000
shares for the year ended December 31, 1999 and 64,271,000 shares for the
three months ended March 31, 2000.

   Pro forma stockholders' equity (unaudited)

   Immediately prior to the effective date of the offering, the Preferred
Stock outstanding will automatically convert into common stock at a one-to-one
ratio. The pro forma effects of this transaction is unaudited and has been
reflected in the accompanying Pro Forma Stockholders' Equity as of March 31,
2000.

   Recent accounting pronouncements

   In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities," which
establishes accounting and reporting standards for derivative instruments and
hedging activities. It requires that an entity recognize all derivatives as
either assets or liabilities in the balance sheet and measure those
instruments at fair value. The Company, to date, has not engaged in derivative
and hedging activities, and accordingly does not believe that the adoption of
SFAS No. 133 will have a material impact on the financial reporting and
related disclosures of the Company. The Company will adopted SFAS No. 133 as
required by SFAS No. 137, "Deferral of the Effective Date of the FASB
Statement No.133," beginning with the third quarter of fiscal 2000.

   In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in
Financial Statements," which provides guidance on the recognition,
presentation, and disclosure of revenue in financial statements filed with the
SEC. SAB 101 outlines the basic criteria that must be met to recognize revenue
and provides guidance for disclosures related to revenue recognition policies.
The Company has complied with the guidance in SAB 101 for all periods
presented.

   In March 2000, the Financial Accounting Standards Board issued
Interpretation No. 44, "Accounting for Certain Transactions Involving Stock
Compensation -- an interpretation of APB Opinion No. 25" ("FIN 44"). This
Interpretation clarifies the definition of employee for purposes of applying
Accounting Practice Board Opinion No. 25, Accounting for Stock Issued to
Employees ("APB 25'), the criteria for determining whether a plan qualifies as
a noncompensatory plan, the accounting consequence of various modifications to
the terms of

a previously fixed stock option or award, and the accounting for an exchange
of stock compensation awards in a business combination. This Interpretation is
effective July 1, 2000, but certain conclusions is this Interpretation cover
specific events that occur after either December 15, 1998, or January 12,
2000. Management believes that FIN 44 will not have a material effect on the
financial position or results of operations of the Company.

   Management believes that, based on a number of factors, it is more likely
than not that the deferred tax assets will not be utilized; and accordingly, a
full valuation allowance has been recorded. The change in the valuation
allowance was $1,734,000 and $10,070,000 for the period from March 20, 1998
(inception) to December 31, 1998 and for the year ended December 31, 1999,
respectively.

   At December 31, 1999, the Company had approximately $25.8 million of
federal and state net operating loss carryforwards available to offset future
taxable income which expire in varying amounts beginning in 2004.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)

Under the Tax Reform Act of 1986, the amounts of and benefits from net
operating loss carryforwards may be impaired or limited in certain
circumstances. Events which cause limitations in the amount of net operating
losses that the Company may utilize in any one year include, but are not
limited to, a cumulative ownership change of more than 50%, as defined, over a
three year period.

5. Capital Lease Obligations

   The Company entered into a master lease agreement with Comdisco, Inc. in
November 1998 with aggregate lines of credit totaling $4.5 million, which
expired in January 2000. The Company received additional lines totaling $1.0
million in September 1999, which expired in September 2000, and an extension
to existing lines for an additional $3.0 million in December 1999, which
expired in January 2000. Advances under the lines are to be repaid over
periods ranging from 30 months to 48 months, bear interest at rates ranging
from 7% to 8%, and are collateralized by the purchased equipment. As of
December 31, 1999, the Company had $2.9 million available under its lease
lines, of which $0.9 million could be used for software, tenant improvements
and tooling specifically approved by Comdisco, Inc. and $2.0 million could be
used for equipment specifically approved by Comdisco, Inc. Warrants were
issued to Comdisco, Inc. in conjunction with the master lease agreement and
each additional increase in credit (see Note 7).

   The advances under the lines have been classified as capital leases. As of
December 31, 1999, the cost of such leased equipment was approximately
$5,850,000 with accumulated amortization of $842,000. As of December 31, 1999,
future minimum lease payments under these agreements are as follows:

6. Commitments and contingencies

   The Company leases office space and equipment under non-cancelable
operating leases with various expiration dates through February 2002. Rent
expense for the period from March 31, 1998 (inception) to December 31, 1998
and for the year ended December 31, 1999 was approximately $107,000 and
$803,000, respectively. The Company also leases bandwidth from a satellite
service provider under a non-cancelable lease agreement, which expires on
December 2002.

   In September and October 1999, the Company entered into three-year service
agreements with Northpoint Communications, Inc. ("NorthPoint") and Covad
Communications Group, Inc. ("Covad"), respectively, to provide streaming video
and audio. Under the terms of the agreements, the Company will deploy its
servers in NorthPoint and Covad hubs in North America and pay up to twenty
percent of all revenues created from the transport of content through their
networks. No amounts have been incurred under these arrangements as of
December 31, 1999.

   In connection with the hiring of David Brewer, Vice President of
Operations, the Company agreed to purchase at least $2.0 million of services
from Brewer Consulting Networks, a company controlled by Mr. Brewer, beginning
January 1, 2000. The obligation to purchase these services from Brewer
Consulting Networks is contingent on Mr. Brewer relinquishing operational or
ownership control of Brewer Consulting Networks.

   The Company is subject to legal proceedings, claims and litigation arising
in the ordinary course of business. The Company's management does not expect
that the ultimate costs to resolve these matters will have a material adverse
effect on the Company's financial position, results of operations, or cash
flows.

   iBEAM's Certificate of Incorporation, as amended, authorizes iBEAM to issue
20 million shares of $0.0001 par value preferred stock in the aggregate.

   The rights, privileges and restrictions of holders of series A, B, C and D
convertible preferred stock ("Series A," "Series B," Series C" and "Series D,"
respectively) are set forth in iBEAM's amended and restated Certificate of
Incorporation, and are summarized as follows:

   Voting

   Each share of Preferred Stock has voting rights equal to an equivalent
number of shares of common stock into which it is convertible and votes
together as one class with the common stock.

   As long as at least any shares of Preferred Stock remain outstanding, the
Company must obtain approval from a majority of the holders of Preferred Stock
in order to alter the Certificate of Incorporation as related to Preferred
Stock, change the authorized number of shares of Preferred Stock, repurchase
any shares of common stock other than shares subject to the right of
repurchase by the Company, change the authorized number of Directors,
authorize a dividend for any class or series other than Preferred Stock,
create a new class of stock or effect a merger, consolidation or sale of
assets where the existing shareholders retain less than 50% of the voting
stock of the surviving entity.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)


   Dividends

   Holders of Series A, B, C and D are entitled to receive noncumulative
dividends at the per annum rate of $0.096, $0.132, $0.274 and $0.477 per
share, respectively, when and if declared by the Board of Directors. The
holders of Preferred Stock will also be entitled to participate in dividends
on common stock, when and if declared by the Board of Directors, based on the
number of shares of common stock held on an as-if converted basis. No
dividends on the Preferred Stock or common stock have been declared by the
Board from inception through December 31, 1999.

   Liquidation

   In the event of any liquidation, dissolution or winding up of the Company,
including a merger, acquisition or sale of assets where the beneficial owners
of the Company's common stock and Preferred Stock own less than 51% of the
resulting voting power of the surviving entity, the holders of Series A, B, C
and D are entitled to receive an amount of $1.20, $1.65, $3.42 and $5.96 per
share, respectively, plus any declared but unpaid dividends prior to and in
preference to any distribution to the holders of common stock. Should the
Company's legally available assets be insufficient to satisfy the liquidation
preferences, the funds will be distributed ratably among the holders of Series
A, B, C and D in proportion to the amount of such stock owed by each holder.
The remaining assets, if any, shall be distributed among the holders of Series
A, B, C and D and common stock pro-rated based on the number of shares of
common stock held by each (assuming full conversion of all such shares Series
A, B, C and D) until the value of the assets distributed to or the
consideration received aggregate $180 million.

   Conversion

   Each share of Preferred Stock is convertible, at the option of the holder,
according to a conversion ratio of 4.131 shares of common stock for one share
of Preferred Stock, subject to adjustment for dilution and common stock
splits, and Preferred Stock automatically converts into the number of shares
of common stock into which such shares are convertible at the then effective
conversion ratio upon: (1) the closing of a public offering of common stock at
a per share price of at least $3.97 per share with gross proceeds of at least
$20 million or (2) the consent of the holders of the majority of Preferred
Stock.

   Warrants for Preferred Stock

   The Company issued warrants to purchase 27,273 and 64,935 shares of Series
B at $1.65 per share and $2.31 per share, respectively, in October 1998, 6,396
shares of Series C at $4.69 per share in September 1999, and 25,168 shares of
Series D at $5.96 per share in December 1999 to Comdisco, Inc. upon signing
various equipment lease lines as described in Note 5. These warrants expire
the earlier of five years from the date of grant or three years from the
effective date of the Company's initial public offering. The Company valued
the warrants using the Black-Scholes option pricing model applying expected
lives of five years, a weighted average risk free rate of 6%, a dividend yield
of zero percent and volatility of 80%. The fair value of approximately
$793,000 represents additional interest on the equipment lease lines and is
being expensed over the lease term using the effective interest rate method.
No amounts were amortized in 1998, and $40,000 was amortized during the year
ended December 31, 1999.

   In October 1999, the Company also issued a warrant to purchase 218,120
shares of Series D at $5.96 per share to a new investor. In September 1999,
the Company entered into sales and marketing cooperative agreement with this
investor. These warrants expire the earlier of seven years from the date of
grant or four years from the effective date of the Company's initial public
offering and were valued using the Black-Scholes option

pricing model applying an expected life of seven years, a weighted average
risk free rate of 6%, a dividend yield of zero percent and volatility of 80%.
The fair value of approximately $1,000,000 represents a non-cash inducement to
enter into future commercial agreements and was included in sales and
marketing expense during the quarter ended December 31, 1999.

8. Benefit Plans

   Stock Option Plan

   On March 23, 1998, the Company adopted the 1998 Stock Option Plan (the
"Plan"). The Plan provides for the granting of stock options to employees and
consultants of the Company. Options granted under the Plan may be either
incentive stock options or non-qualified stock options. Incentive stock
options ("ISO") may be granted only to Company employees (including officers
and directors who are also employees). Non-qualified stock options ("NSO") may
be granted to Company employees and consultants. As of December 31, 1999, the
Company had reserved approximately 22,038,000 shares of common stock for
issuance under the Plan.

   Options under the Plan may be granted for periods of up to ten years and at
prices no less than 85% of the estimated fair value of the shares on the date
of grant as determined by the Board of Directors, provided, however, that (i)
the exercise price of an ISO and NSO shall not be less than 100% and 85% of
the estimated fair value of the shares on the date of grant, respectively, and
(ii) the exercise price of an ISO and NSO granted to a 10% shareholder shall
not be less than 110% of the estimated fair value of the shares on the date of
grant. Options are exercisable immediately subject to repurchase options held
by the Company which lapse with the options vesting schedule. Options may have
a maximum term of up to 10 years as determined by the Board of Directors. To
date, options granted generally vest over four years.

   The following table summarizes activity under the Plan since inception (in
thousands, except per share data):

   Fair value disclosures

   Had compensation cost for the Company's stock-based compensation plan been
determined based on the fair value at the grant dates for the awards under a
method prescribed by SFAS No. 123, the Company's net loss would have been
increased to the pro forma amounts indicated below:

   The Company calculated the value of each option grant on the date of grant
using the Black-Scholes option pricing model with the following assumptions
for all periods: dividend yield expected and volatility of 0%; expected lives
of four years and risk free interest rate of 5.75%. These pro forma amounts
may not be representative of the effects on reported net loss for future years
as options vest over several years and additional awards are generally made
each year. The weighted average fair value of options granted was $0.19 and
$1.80 for the period from March 20, 1998 (inception) to December 31, 1998 and
for the year ended December 31, 1999, respectively.

   Stock-based compensation

   In connection with certain stock option grants to employees and board
members, the Company recognized approximately $608,000, $17,290,000 and
$10,577,000 (unaudited) of unearned stock-based compensation for the excess of
the deemed fair market value over the exercise price at the date of grant for
the period from March 10, 1998 (inception) to December 31, 1998, for the year
ended December 31, 1999 and for the three months ended March 31, 2000,
respectively. The compensation expense is being recognized, using the multiple
option method as prescribed by FASB Interpretation No. 28, over the option's
vesting period of generally four

years. As a result, the Company recorded stock-based compensation expense of
$31,000, $4,974,000 and $2,920,000 (unaudited) for the period from March 20,
1998 (inception) to December 31, 1998, for the year ended December 31, 1999
and for the three months ended March 1, 2000, respectively.

   Stock-based compensation expense related to stock options granted to
consultants is recognized as the stock options are earned. The fair value of
the stock options granted is calculated at each reporting date using the
Black-Scholes option pricing model. As a result, the stock-based compensation
expense will fluctuate as the fair market value of our common stock
fluctuates. The Company believes that the fair value of the stock options are
more reliably measurable than the fair value of the services received. In
connection with the grant of stock options to consultants, the Company
recorded stock-based compensation expense of $8,000, $419,000 and $1,174,000
for the period from March 20, 1998 (inception) to December 31, 1998, for the
year ended December 31, 1999, and for the three month ended March 31, 2000,
respectively.

   As of March 31, 2000, the Company expects to amortize stock-based
compensation expense of $12,227,000 in the remainder of fiscal 2000,
$9,262,000 in 2001, $4,843,000 in 2002, and $2,054,000 in 2003.

   401(k) Plan

   The Company's employee savings and retirement plan is qualified under
Section 401 of the Internal Revenue Code. Employees may elect to reduce their
current compensation by up to the statutorily prescribed annual limit and have
the amount of such reduction contributed to the 401(k) Plan. The Company
currently does not make matching or additional contributions to the 401(k)
Plan on its employees' behalf.

9. Segment Information

   The Company currently operates in a single business segment as there is
only one measurement of profitability for its operations. Through December 31,
1999, foreign operations have not been significant in either revenues or
investments in long-lived assets.

shares will automatically convert into 3,505,089 shares of common stock upon
the closing of this offering. The difference between the mid-point of the
estimated price range for shares in the Company's initial public offering
("IPO") and the conversion price resulted in a beneficial conversion feature
of approximately $10.8 million. Under Emerging Issues Task Force No. 98-5,
Accounting for Convertible Securities with Beneficial Conversion Features, the
beneficial conversion feature resulted in a "deemed" preferred dividend of
$10.8 million for the three months ended March 31, 2000.

   Acquisition of webcasts.com, Inc.

   In March 2000, the Company entered into an agreement to acquire with
webcasts.com, Inc. ("webcasts.com"), a provider of interactive broadcasting
services and proprietary tools that give businesses the ability to conduct
live and on-demand Internet broadcasts for use in distance learning, corporate
communications, sales presentations, on-line trade shows and interactive
television. The acquisition was consummated on April 28, 2000 and was
accounted for as a purchase business combination with a purchase price of
$92.2 million.

   Under the terms of the agreement, all issued and outstanding shares and
warrants of webcasts.com were exchanged for 8,233,173 shares of the Company's
series F redeemable convertible preferred stock ("Series F") equal to 8% of
the as adjusted capitalization of the combined companies immediately following
the acquisition. Such shares had a value of approximately $82.3 million. In
addition, based on an exchange ratio of 0.34743 shares of iBEAM for every
share of webcasts.com, all of the outstanding options granted under the
webcasts.com 1999 Stock Option Plan converted into options to purchase 706,285
shares of the Company's Series F. The fair value of these options of
approximately $5.2 million was determined using the Black-Scholes option
pricing model and is included as a component of the purchase price. The
Company also issued a $3.0 million note to the webcasts.com's redeemable
preferred stockholders, which is payable on September 20, 2000 and bears
interest at 10% per annum. The Company anticipates incurring approximately
$1.7 million in acquisition related expenses, which consist primarily of
financial advisory, accounting and legal fees. See Unaudited Pro Forma
Combined Financial Information.

   America Online, Inc.

   In February 2000, the Company entered into a two year commercial agreement
with America Online, Inc. to deploy the Company's streaming media distribution
network within America Online's network. Under the agreement, the Company
agreed to pay an advance of $3.0 million against future revenue sharing
obligations derived from content delivered through their network. In the event
the Company does not deliver a minimum amount of traffic to America Online,
they can terminate this agreement, at which time, a portion of the advance
will be refunded to the Company. In addition, America Online may purchase
services pursuant to the Company's standard service terms and conditions.

   In February 2000, America Online purchased $5 million of Series E for
$13.75 per share, which converts into 500,726 shares of common stock at the
closing of this offering, and received a warrant to purchase 537,634 shares of
our common stock at an exercise price equal to the price to public in this
offering, less underwriting discounts and commissions. The warrant was a
condition to the commercial agreement and was valued using the Black-Scholes
option pricing model. The fair value of $2.8 million represents an expense for
receiving equipment rack space at each of America Online's data centers and
will be recognized ratably over the term of the agreement.

   In January 2000, the Board of Directors adopted, subject to stockholder
approval, the 2000 Director Option Plan (the "Director Plan"). The Director
Plan provides for the periodic grant of nonstatutory stock options to non-
employee directors. A total of 500,000 shares were reserved for issuance under
the Director Plan.

   In January 2000, the Board of Directors adopted, subject to stockholder
approval, the 2000 Employee Stock Purchase Plan (the "Purchase Plan"), which
was subsequently amended in May 2000. A total of 1,500,000 shares of common
stock will be made available under the Purchase Plan. The Purchase Plan
provides for annual increases in the number of shares available for issuance
on January 1st of each year, beginning in 2001, equal to the lesser of (i) 2%
of the outstanding shares of common stock on the first day of the calendar
year, (ii) 3,000,000 shares, or (iii) such other lesser amount as determined
by the Board of Directors. The Purchase Plan is intended to qualify for
preferential tax treatment and contains consecutive, overlapping 24-month
offering periods. Each offering period includes four 6-month purchase periods.
The offering periods generally start on the first trading day on or after
February 1 and August 1 of each year, except for the first such offering
period which will commence on the first trading day on or after the effective
date of this offering and will end on the last trading day on or before
January 31, 2001. The Purchase Plan permits participants to purchase common
stock through payroll deductions of up to 15% of their eligible compensation.
A participant may purchase no more than 10,000 shares during any 6-month
purchase period. Amounts deducted and accumulated by the participant are used
to purchase shares of our common stock at the end of each 6-month purchase
period. The price is 85% of the lower of the fair market value of our common
stock at the beginning of an offering period or after a purchase period ends.

              UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

                                   OVERVIEW

   On March 21, 2000, iBEAM Broadcasting Corporation ("iBEAM" or the
"Company") entered into a definitive agreement to acquire webcasts.com, Inc.
("webcasts.com") in a transaction to be accounted for as a purchase business
combination. Webcasts.com provides interactive broadcasting services and
proprietary tools that give businesses the ability to conduct live and on-
demand Internet broadcasts for use in distance learning, corporate
communications, sales presentations, on-line trade shows and interactive
television.

   On April 28, 2000, the Company consummated this acquisition. All issued and
outstanding shares and warrants of webcasts.com were exchanged for shares of
the Company's series F redeemable convertible preferred stock ("Series F")
equal to 8% of the as adjusted capitalization of the combined companies
immediately following the acquisition. Using the capitalization of the
companies as of April 28, 2000 as adjusted for the planned issuance of
1,537,634 shares of preferred stock to The Walt Disney Company and Excite@Home
and the repurchase of 908,820 shares of common stock in May 2000, the Company
issued 8,233,173 shares, at $10.00 per share, for a value of approximately
$82.3 million. In addition, based on an exchange ratio of 0.34743 shares of
iBEAM for every share of webcasts.com, all of the outstanding options granted
under the webcasts.com 1999 Stock Option Plan were converted into options to
purchase 706,285 shares of the Company's Series F. The fair value of these
options of approximately $5.2 million was determined using the Black-Scholes
option pricing model and is included as a component of the purchase price. The
Company also issued a $3.0 million note to the webcasts.com's redeemable
preferred stockholders, which is payable on September 20, 2000 and bears
interest at 10% per annum. The Company anticipates incurring approximately
$1.7 million in acquisition related expenses, which consist primarily of
financial advisory, accounting and legal fees. In addition, the former
securityholders of webcasts.com may receive an additional 1,243,932 shares of
common stock if the webcasts.com subsidiary meets revenue targets in the
twelve months after the closing of the acquisition.

   The total purchase price of $92.2 million will be allocated to the assets
acquired, including tangible and intangible assets, and liabilities assumed
based upon the fair value of such assets and liabilities on the date of
acquisition. The total estimated purchase price of the acquisition has been
allocated based on a preliminary basis to assets and liabilities based on
management estimates of their fair value and an independent appraisal of
certain intangible assets with the excess cost over the net assets acquired
allocated to goodwill. This allocation is subject to change pending a final

</TABLE>

   The tangible assets consist primarily of cash and cash equivalents,
accounts receivable and property and equipment. The liabilities assumed
consist primarily of accounts and notes payable and a revolving line of
credit. Webcasts.com's tangible assets received and liabilities assumed as of
March 31, 2000 were used for purposes of calculating the pro forma adjustments
as they approximate fair value at such date. The amounts allocated to
purchased technology, assembled workforce, and non-competition agreements are
being amortized over their estimated useful lives of three years. The purchase
price in excess of net identified tangible and intangible assets is allocated
as goodwill, which is being amortized over three years.

   The acquisition is expected to be structured as a tax-free exchange of
stock, therefore, the differences between the recognized fair values of
acquired assets, including tangible and intangible assets and their historical
tax bases, are not deductible for tax purposes.

          NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

1. Basis of presentation

   The unaudited pro forma combined balance sheet gives effect to this
acquisition as if it occurred on March 31, 2000 and combines the balance sheet
of iBEAM as of March 31, 2000 and the consolidated balance sheet of
webcasts.com as of March 31, 2000.

   On October 15, 1999, webcasts.com completed its acquisition of all the
outstanding capital stock of The Rock Island Group, Inc. ("RIG"). The RIG
acquisition was accounted for using the purchase method of accounting and,
accordingly, the net assets and results of operations of RIG have been
included in the consolidated financial statements of webcasts.com since the
acquisition date.

   The unaudited pro forma statement of operations gives effect to the
webcasts.com acquisition as if it had occurred on January 1, 1999 and presents
the results of operations of iBEAM for the year ended December 31, 1999
combined with the unaudited pro forma statement of operations of webcasts.com
for the year ended December 31, 1999. The unaudited pro forma statement of
operations of webcasts.com includes the results of operations of webcasts.com
for the year ended December 31, 1999 combined with the results of operations
of RIG for the period from January 1, 1999 to October 14, 1999 as if the RIG
acquisition occurred on January 1, 1999.

   The unaudited pro forma combined information is presented for illustrative
purposes only and is not necessarily indicative of the operating results or
financial position that would have occurred if the transactions had been
consummated at the dates indicated, nor is it necessarily indicative of the
future operating results or the financial position of the combined companies.

2. Pro forma adjustments

   The following adjustments were applied to iBEAM's historical financial
statements and those of webcasts.com to arrive at the pro forma combined
financial information:

  A  To eliminate the intercompany promissory note.

  B  To reflect the issuance of Series F preferred stock and the assumption
     of options to purchase Series F preferred stock in connection with the
     acquisition of webcasts.com and to record the issuance of a $3.0 million
     note payable by iBEAM to webcasts.com's redeemable preferred
     stockholders, estimated transaction costs of $1.7 million and other
     assets and liabilities at their fair value.

  C  To reflect the amortization of goodwill and other intangibles over their
     estimated useful lives as follows:

Non-compete agreements..    4,700   3 years           1,567               392
</TABLE>

     The estimated useful life related to the assembled workforce was based
     on the remaining vesting schedule of the employees' stock options and
     the historical experience of employee turnover. The estimated useful
     life related to the non-compete agreement was based on the term of the
     non-compete provisions.

  D  Pro forma basic and diluted net loss per share attributable to common
     stock is computed using the weighted average number of common shares
     outstanding, including the pro forma effects of the automatic conversion
     of the Company's outstanding redeemable convertible preferred stock
     effective upon the closing of the Company's initial public offering as
     if such conversion occurred on January 1, 1999, or at the date of
     original issuance, if later. The shares of Series F, issued as
     consideration for the

     acquisition, are assumed to be converted into the Company's common stock
     under the automatic conversion feature and outstanding as of January 1,
     1999. Common stock subject to repurchase rights and incremental shares
     of common and preferred stock issuable upon the exercise of stock
     options and warrants, aggregating 22,258,000 shares at March 31, 2000
     and 18,657,000 shares at December 31, 1999, have been excluded from the
     diluted net loss per share calculation because to do so would be
     antidilutive.

  E  To eliminate revenue related to product sales to webcasts.com by RIG
     prior to webcasts.com's acquisition of RIG. Additionally, the related
     cost of revenue recognized by RIG has been eliminated.

  F  To reflect additional depreciation expense on the fair value of tangible
     assets acquired.

  G  To record the additional amortization of goodwill related to the
     acquisition of RIG as if the transaction occurred on January 1, 1999.

  H  To reduce interest expense, resulting from the settlement of notes
     payable in connection with the acquisition of RIG as if the settlement
     occurred on January 1, 1999.

estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

                       WEBCASTS.COM, INC. AND SUBSIDIARY

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                        December 31, 1998 and 1999

       (Information insofar as it relates to March 31, 2000 and the

         three months ended March 31, 1999 and 2000 is unaudited)

(1) Summary of Significant Accounting Policies

   (a) Organization, Nature of Business and Basis of Presentation

   webcasts.com, Inc. (the Company) was founded in 1995 as an interactive
digital marketing agency that also develops proprietary technologies. These
tools include Internet/Web development and CD-Roms which accounted for
approximately 52% of revenues in 1999. The Company also provides custom
programming, consulting, and other digital products and services as well as
network design, implementation and management based upon specific needs of
clients which accounted for approximately 23% of revenues in 1999. During
1997, the Company launched a business to become a web-based interactive
broadcasting provider that enables web site and content owners to provide high
quality streaming of live and on-demand audio and video content over the
Internet which accounted for approximately 13% of revenues in 1999. The
Company provides all of the infrastructure to facilitate end-to-end
broadcasting which includes production capabilities, sponsorship revenue
generation, a network for the delivery of rich media including video, audio,
text, graphics and animations, and an integrated, e-commerce enabled
interface.

   In the opinion of management, the accompanying unaudited financial
statements as of March 31, 2000 and for the three months ended March 31, 1999
and 2000, reflect adjustments (all of which are normal and recurring) which,
in the opinion of management, are necessary for a fair presentation of the
financial position and results of operations of the interim periods presented.

   (b) Principles of Consolidation

   The consolidated financial statements include the accounts of webcasts.com,
Inc. and its wholly owned subsidiary. All significant intercompany balances
and transactions have been eliminated in consolidation.

   (c) Use of Estimates in the Preparation of Financial Statements

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

   (d) Revenue and Cost Recognition

   Revenue is recognized on the completed contract method for all revenue
streams due to the short-term nature of the contracts, generally one to three
months in duration. The Company's revenue streams consist generally of four
types: Internet/Web development and CD-ROMs; custom programming and consulting
for digital products and services; network design, implementation and
management; and web-based interactive broadcasting of high quality streaming
of live and on-demand audio and video content over the Internet.

   Revenue is recognized upon completion of the contract. Indirect costs and
general and administrative expenses are expensed as incurred. Contract costs,
consisting primarily of direct labor and material costs, and related revenues
are deferred in the balance sheet until completion. A contract is considered
complete when all costs have been incurred and the product is performing
according to specifications or has been accepted by the customer. The Company
also records deferred revenues for advance payment on customer projects. The
deferred revenues are recorded as income in the period the services are
provided.

                                     F-33
<PAGE>


                    WEBCASTS.COM, INC. AND SUBSIDIARY

                NOTES TO FINANCIAL STATEMENTS--(Continued)

   Costs of revenues include all direct labor and material costs and those
indirect costs related to contract performance. Operating expenses are charged
to expense as incurred. Provisions for estimated losses on uncompleted
contracts are made in the period in which such losses are determined.

   (e) Allowance for Doubtful Trade Accounts Receivable

   The Company extends credit to customers in accordance with normal industry
standards and terms. The Company has established an allowance for doubtful
accounts based on known factors surrounding the credit risk of specific
customers, historical trends and other information. The Company may require
that a portion of the estimated billings be paid prior to delivering products
or performing services. In addition, the Company may terminate customer
contracts if outstanding amounts are not paid.

   (f) Warrants to Purchase Common Stock

   The Company has issued debt and preferred stock with detachable common
stock purchase warrants. The stock purchase warrants are initially recorded
based on their fair value with the balance of the proceeds allocated to the
debt or preferred stock. The debt is accreted to its face value over its term
and the accretion is recorded as interest expense in the accompanying
statements of operations. Preferred stock which is redeemable for cash at the
option of the holder is accreted to its redemption value and the accretion is
recorded as a decrease to additional paid in capital in the accompanying
statement of stockholders' equity (deficit). Warrants are initially recorded
in stockholders' equity (deficit) and warrants which may be put back to the
Company for cash at the option of the holder are accreted to the put value
over the period from the date of issuance to the earliest put date of the
warrants.

   (g) Equipment

   Equipment, stated at cost or the present value of minimum lease payments
for assets under capital leases, is depreciated over the estimated useful
lives of the assets using the straight-line method. Estimated useful lives
range from 3 to 7 years. Significant improvements and betterments are
capitalized if they extend the useful life of the asset. Routine repairs and
maintenance are expensed when incurred.

   The Company reviews long-lived assets for impairment whenever events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows
expected to be generated by the asset. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which
the carrying amount of the assets exceed the fair value of the assets. Assets
to be disposed of are reported at the lower of the carrying amount or fair
value less costs to sell.

   (h) Research and Software Development Costs

   Research and development costs are charged to operations as incurred.
Software development and prototype costs incurred prior to establishment of
technological feasibility are included in research and development and are
expensed as incurred. Software development costs incurred subsequent to the
establishment of technological feasibility until general market availability
of the product are capitalized, if material. To date, all software development
costs incurred subsequent to the establishment of technological feasibility
have been expensed as incurred due to their immateriality.

   (i) Income Taxes

   During 1998 the Company was taxed as an S-Corporation under the Internal
Revenue Code. As such, income taxes were the responsibility of the
shareholders and were not accounted for in the consolidated financial

                                     F-34
<PAGE>


                    WEBCASTS.COM, INC. AND SUBSIDIARY

                NOTES TO FINANCIAL STATEMENTS--(Continued)

statements of the Company. In 1999, the Company received permission from the
Internal Revenue Service to change its election from an S-Corporation and,
effective January 1, 1999, is taxed as a C-Corporation. As a result, income
taxes are accounted for using the asset and liability method under which
deferred income taxes are recognized for the tax consequences of "temporary
differences" by applying enacted statutory tax rates to differences between
the financial statement carrying amounts and the tax bases of existing assets
and liabilities and tax operating loss carryforwards. The effect on deferred
taxes for a change in tax rates is recognized in income in the period that
includes the enactment date. The effect of recognizing deferred tax assets and
liabilities due to the change in tax status is included in income tax expense
and is fully offset by the income tax benefit generated in 1999.

   (j) Stock Options

   The Company accounts for stock-based compensation using the intrinsic value
method prescribed in Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees," (APB No. 25), and related interpretations.
Compensation expense is recorded on the date of grant only if the current
market price of the underlying stock exceeds the exercise price of the stock
options, and the expense is recognized over the vesting period.

   Stock options and warrants issued to non-employees for services rendered
are recorded as expense upon issuance based on their estimated fair value.

   (k) Loss per Share

   Loss per share is computed by dividing net loss applicable to common stock
by the weighted average number of common shares outstanding for the period.
The effect of warrants to purchase common stock, convertible preferred stock,
and stock options has been excluded since the effect would be anti-dilutive.

   (l) Goodwill

   Goodwill, which represents the excess of purchase price over fair value of
net assets acquired, is amortized on a straight-line basis over the expected
periods to be benefited. The Company assesses the recoverability of this
intangible asset by determining whether the amortization of the goodwill
balance over its remaining life can be recovered through undiscounted future
operating cash flows of the acquired operation. The amount of goodwill
impairment, if any, is measured based on projected discounted future operating
cash flows using a discount rate reflecting the Company's average cost of
funds. The assessment of the recoverability of goodwill will be impacted if
estimated future operating cash flows are not achieved.

   (m) Recent Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, "Accounting for Derivative Instruments and Hedging Activities," which
establishes accounting and reporting standards for derivative instruments and
hedging activities. It requires that an entity recognize all derivatives as
either assets or liabilities in the balance sheet and measure those
instruments at fair value. The Company, to date, has not engaged in derivative
and hedging activities, and accordingly does not believe that the adoption of
SFAS No. 133 will have a material impact on the financial reporting and
related disclosures of the Company. The Company will adopt SFAS No. 133 as
required by SFAS No. 137, "Deferral of the Effective Date of the FASB
Statement No. 133," beginning with the first quarter of 2001.

   In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in
Financial Statements," which provides guidance on the recognition,
presentation, and disclosure of revenue in financial statements filed with the
SEC. SAB 101 outlines the basic criteria that must be met to recognize revenue
and provides guidance for disclosures related to revenue

recognition policies. Management believes that the impact of SAB 101 will not
have a material effect on the financial position or results of operations of
the Company.

   In March 2000, the FASB issued Interpretation No. 44, "Accounting for
Certain Transactions Involving Stock Compensation--an interpretation of APB
Opinion No. 25" ("FIN 44"). Among other issues, this interpretation clarifies
the definition of employee for purposes of applying APB Opinion No. 25,
Accounting for Stock Issued to Employees ("APB 25"), the criteria for
determining whether a plan qualifies as a noncompensatory plan, the accounting
consequence of various modifications to the terms of a previously fixed stock
option or award, and the accounting for an exchange of stock compensation
awards in a business combination. This Interpretation is effective July 1,
2000, but certain conclusions in this Interpretation cover specific events
that occur after either December 15, 1998, or January 12, 2000. Management
believes that FIN 44 will not have a material effect on the financial position
or results of operations of the Company.

(2) Acquisition of The Rock Island Group, Inc.

   On October 15, 1999, the Company acquired The Rock Island Group, Inc.
(RIG), a network design, implementation and management company for
approximately $5,000,000. The Company issued 210,000 shares of Series D Senior
Convertible Preferred Stock, granted 20,000 options to purchase Series D
Senior Convertible Preferred Stock at an option price of $.01, and assumed
liabilities of approximately $1,000,000 in exchange for all of the outstanding
common and preferred shares of RIG. The purchase price was allocated to the
assets acquired based on their estimated fair values, and approximately
$450,000 was allocated to current assets. The excess of the purchase price
over the fair value of the net assets acquired was approximately $4 million
and is being amortized on a straight-line basis over 7 years. In determining
the purchase price allocation, the Company identified intangible assets
consisting of customer base and assembled workforce. The allocation of the
purchase price to these identifiable assets would not materially impact the
financial position or the results of operations for 1999 or future results.

   The acquisition was accounted for by the purchase method of accounting for
business combinations. Accordingly, the accompanying consolidated statements
of operations do not include any revenues or expenses related to the
acquisition prior to the closing date.


(3) Notes Payable and Revolving Line of Credit

   In February 1998, the Company entered into an agreement to transfer up to
$450,000 of trade receivables with full recourse. The agreement allowed the
Company to remit receivables with an aggregate face value of $450,000 to a
bank; however, the bank had no obligation to purchase the receivables. For a
receivable accepted in accordance with the agreement, the bank would remit 80%
of the face value to the Company. The remaining 20% was remitted to the
Company after collection of the receivable by the bank. Proceeds from the
transfers contemplated by this agreement, which totaled $153,083 at December
31, 1998, are reported as borrowings in accordance with Statement of Financial
Accounting Standards No. 125, "Accounting for Transfers and Servicing of
Financial Assets and Extinguishment of Liabilities," and are included in notes
payable in the accompanying 1998 balance sheet. The bank received monthly
interest of 2.75% of the average daily balance of the receivables purchased
and an administrative fee of 1% of all receivables purchased. The
administrative fees are included in operating expenses in the accompanying
statement of operations. The borrowings were secured by all assets of the
Company and a personal guaranty of the president of the Company.

   The receivable transfer agreement was terminated in May 1999, and replaced
with a revolving line of credit with a separate financial institution in the
amount of $2,000,000 in September 1999. The revolving line of credit is
comprised of a working capital loan not to exceed $1,000,000 and an equipment
loan not to exceed $1,000,000. The working capital loan expires September 15,
2000, and there were no borrowings against the loan at

December 31, 1999 and approximately $113,000 borrowed at March 31, 2000. The
equipment loan expires September 15, 2002, and there was $978,480 borrowed
against the loan at December 31, 1999 and March 31, 2000. The loans are
secured by equipment and trade accounts receivable and bear interest at the
prime rate plus 1% (approximately 9.5% and 9.75% at December 31, 1999 and
March 31, 2000, respectively).

   In August 1998, the Company borrowed $50,000 from two individuals which was
included in notes payable at December 31, 1998. The promissory notes accrued
interest at 8% and were convertible to common shares of the Company at
maturity of the notes. The notes were converted to common stock in May 1999.

   The Company has three promissory notes to a financial institution
outstanding which bear interest at rates ranging from 8.75% to 10.5% at
December 31, 1999. The notes are secured by equipment, fixtures and accounts
receivable. The notes are due as follows: $63,777 in 2000; $17,306 in 2001;
$20,670 in 2002; and $13,596 in 2003.

   During 1998, the Company entered into an agreement to purchase 2,392,006
shares of the Company's common stock from two significant stockholders for
$450,000. Each stockholder received $20,000 upon execution of the agreement; a
promissory note in the amount of $180,000, due November 30, 1998, bearing
interest at 8%, secured by all assets of the Company; and an unsecured
promissory note in the amount of $25,000 to be paid in monthly installments of
$1,000, plus accrued interest at 8%. Each stockholder received payments of
$2,000 on the unsecured notes during 1998. The stockholders extended the
payment terms of the secured promissory notes and during May 1999 the
agreement was restructured and the stockholders transferred approximately
1,500,000 additional shares to the Company. The Company then paid the
promissory notes in full.

   The Company had a note payable to the President of the Company in the
amount of $13,000 at December 31, 1998. The note accumulated interest at 8%
and was included in notes payable to common stockholders in the accompanying
1998 balance sheet. The note was repaid in 1999.

   During November 1999, the Company issued unsecured bridge promissory notes
to preferred stockholders in the aggregate amount of $3,000,000. The notes
bear interest at 10% with interest and principal due on September 30, 2000.
The notes were issued with detachable common stock purchase warrants (the
Bridge Warrants) and the recorded value is net of amounts allocated to the
Bridge Warrants. The debt increased approximately $31,000 and $62,000 for the
accretion of the debt to its face value during 1999 and the three months ended
March 31, 2000, respectively. The promissory notes were converted to 120,000
shares of Series D Preferred Stock on February 29, 2000.

   In March 2000, the Company entered into a $10,000,000 promissory note with
iBEAM Broadcasting Corporation (iBEAM). The note bears interest at prime rate
+1%, with principal and interest due at maturity on March 1, 2001.

(4) Redeemable Preferred Stock

   During May and June 1999, the Company issued 23,093 shares of Series A
Senior Preferred Stock (Series A Stock), 3,000 shares of Series B Senior
Preferred Stock (Series B Stock), and 4,000 shares of Series C Senior
Preferred Stock (Series C Stock) (collectively the Preferred Stock), together
with detachable warrants to purchase an aggregate of 7,756,243 shares of
common stock (Preferred Warrants), for approximately $3,000,000. The Preferred
Stock is not convertible, ranks senior to the common stock and Series D
Preferred Stock of the Company and has a liquidation preference of $200 per
share plus all accrued, accumulated and unpaid dividends. Dividends on the
Preferred Stock are cumulative and accrue at an annual rate of $8 per share,
payable quarterly when and if declared by the Company. As of December 31, 1999
and March 31, 2000, cumulative dividends in arrears for the Preferred Stock
were approximately $120,000 and $180,000, respectively. The Company may elect
to pay all or part of dividends declared before June 30, 2002 by issuing
additional Preferred Stock and Preferred Warrants. All dividends not declared
before the earlier of a Qualified Public Offering, as defined in the Preferred

                NOTES TO FINANCIAL STATEMENTS--(Continued)

Stock purchase agreements, or June 30, 2004 will be deemed to have not
accumulated and will not be required to be paid or declared.

   The holders of the Series A and B Stock have voting rights equivalent to
23.10 common shares and holders of Series C Stock have voting rights
equivalent to 14.684 common shares. The holders of the Preferred Stock, voting
together as a class, are entitled to elect two directors of the Company,
including Chairman of the Board, and certain actions of the Company require
approval by the holders of the Preferred Stock. These rights terminate upon
redemption of all of the Preferred Stock.

   The Preferred Warrants have an exercise price of less than $.01 and may be
exercised at any time prior to expiration. Approximately 6,255,000 of the
Preferred Warrants expire in May 2009 and approximately 1,501,000 Preferred
Warrants expire in June 2009.

   The Company may redeem the Preferred Stock for cash at any time for $200
per share plus all accrued, accumulated and unpaid dividends. The owners of
the Preferred Stock have the option any time after May 14, 2003, to require
the Company to redeem one or more shares of their Preferred Stock at the
liquidation preference of $200 per share. In addition, each owner of the
Preferred Stock, the related Preferred Warrants, and shares obtained through
exercise of the Preferred Warrants, have the option any time after May 14,
2004 but before May 14, 2006 to require the Company to purchase all or part of
their Preferred Stock, Preferred Warrants or shares obtained through exercise
of the Preferred Warrants at the fair value of the securities. The estimated
fair value of the Preferred Warrants is approximately $14,100,000 at December
31, 1999. The Preferred Warrants were exercised on March 31, 2000 for
7,756,000 shares of common stock.

(5) Stockholders' Equity (Deficit)

   Common Stock

   During 1999, the board of directors and shareholders of the Company
approved amended and restated certificates of incorporation which ultimately
authorized 50,000,000 shares of common stock ($.00001 par value) and 2,000,000
shares of preferred stock ($.0001 par value). In addition, the Company
increased its outstanding shares through two splits of the common stock
aggregating 21,458-for-1. The Company's common stockholders have entered into
an agreement which provides for restrictions on transfers of stock and certain
rights of first refusal of shares of stock offered for sale by stockholders.
All share information has been restated for the stock splits.

   Preferred Stock and Preferred Stock Options

   As discussed in note 2, 210,000 shares of the Series D Senior Convertible
Preferred Stock (Series D Stock) and options to purchase 20,000 shares of
Series D Stock were issued in 1999 in connection with the acquisition of RIG.
The Series D Stock ranks senior to the common stock of the Company and has a
liquidation preference of $17.39 per share plus all accrued, accumulated and
unpaid dividends. Dividends on the Series D Stock are cumulative and accrue at
an annual rate of $1.22 per share, payable quarterly when and if declared by
the Company. As of December 31, 1999 and March 31, 2000, cumulative dividends
in arrears for the Series D Stock were approximately $53,000 and $120,000,
respectively. The holders of the Series D Stock have voting rights equivalent
to those of common stockholders. The options to purchase additional Series D
Stock have an exercise price of $.01 per share, a term of 10 years and fully
vested on March 31, 2000. No options to purchase the Series D Stock have been
exercised as of December 31, 1999.

   The Series D Stock and related options are convertible to an aggregate of
2,300,000 shares of the Company's common stock at any time, however, if not
converted prior to the Company's next private placement of equity securities
and the fair value of the Company is determined to be less than $40,000,000 at
the time of the private placement, the Series D Stock and related options are
convertible into 2,400,000 shares of the Company's common stock. In addition,
the Series D Stock and related options are automatically converted upon

to purchase 4,500 shares of Series D Stock were exercised in the three months
ended March 31, 2000, and 15,500 options remain outstanding at March 31, 2000.

   Warrants to Purchase Common Stock

   As discussed in note 3, the Company issued unsecured bridge promissory
notes with detachable Bridge Warrants during 1999. The amount of Bridge
Warrants to be issued to each holder is equal to 10% of the unsecured bridge
promissory notes (total of $300,000) divided by (a) the implied value of one
share of common stock in a Qualified Transaction or (b) $1.75 in the event a
private placement does not occur prior to the maturity of the Bridge Warrants
on November 30, 2009. The Bridge Warrants are exercisable any time after a
Qualified Transaction and before maturity at an exercise price of $.01. The
Bridge Warrants were exercised in the three months ended March 31, 2000 for
120,000 shares of common stock.

   The Company also issued warrants to purchase 47,406 shares of common stock
at an exercise price of $.01 to a third party in exchange for services
provided to the Company. These warrants are exercisable any time prior to

                NOTES TO FINANCIAL STATEMENTS--(Continued)

   A valuation allowance has been provided for the deferred tax assets because
the Company's management has determined it is more likely than not that the net
deferred tax asset will not be realized.

   At December 31, 1999 the Company has net operating loss carryforwards of
approximately $7,900,000 for federal and state income tax purposes and the
carryforwards expire in 2011 to 2015. Approximately $4,200,000 of the net
operating loss carryforwards were generated by RIG prior to the acquisition
(see note 2) and begin to expire in 2011. Utilization of these carryforwards is
limited by section 382 of the Internal Revenue Code (section 382). In addition,
changes in ownership, as defined by section 382, during 1999 and in future
periods could limit the amount of net operating loss carryforwards used in any
one year. Any tax benefit recognized as a result of utilization of RIG pre-
acquisition tax operating losses will reduce goodwill recorded in connection
with the RIG acquisition and will not reduce future financial income tax
expense.

(10) Employment Agreements

   The Company has employment agreements with four key executive officers which
expire in May 2002. In addition to a base salary, the agreements provide for an
annual performance bonus of up to $50,000 and six months severance if
terminated without cause. Two of the officers owned approximately 7,100,000
shares of common stock upon execution of the employment agreements, and two of
the officers were granted approximately 2,000,000 shares of common stock.
Approximately 29% of the 2,000,000 shares granted is subject to repurchase if
specific web-based broadcasting revenue targets are not achieved. If the
employees resign or are terminated with cause, 75% of the stock not repurchased
based on the specific revenue targets is subject to further repurchase.

(11) Stock Option Plan

   During 1999, the Company adopted a stock option plan (the Plan) and
authorized the issuance of incentive and non-qualified options to purchase
2,200,000 shares of the Company's common stock. All employees have the ability
to earn stock options through a performance option program and all options
granted in 1999 were non-qualified and issued at a discount of approximately
15% from the fair value of the Company's common stock. Each option allows the
applicable employee to purchase one share of common stock at the exercise price
determined by the board of directors. Options become exercisable at a rate of
no less than 20% per year over five years from the grant date. The exercise
price for an employee who owns stock representing more than ten percent of all
voting power of all classes of common stock shall be no less than 110% of the
fair value of the common stock on the date of grant. The exercise price for all
other employees shall be no less than 85% of the fair value of the common stock
on the grant date. The term of each option can be no more than ten years from
the date of grant. If a participant owns stock representing more than ten
percent of the voting power of all classes of stock of the Company, the term of
the option will be five years from the date of grant.

</TABLE>

   The Company applies APB Opinion 25 and related interpretations in accounting
for its Plan. The amount of expense recognized in 1999 related to employee
stock options was $33,000. No expense was recognized in 1998, since no options
were granted until 1999. Had the Company applied SFAS 123 in accounting for the
plans, the additional compensation costs would have been approximately $64,000.
The fair value of each option grant was estimated using an option-pricing model
with the following weighted-average assumptions: dividend yield of 0%; expected
volatility of 0%; risk-free interest rate of 5.5% and expected lives of
approximately five years.

(12) 401(k) Plan

   During 1999, the Company established a 401(k) plan in which substantially
all employees of the Company are eligible to participate. Company contributions
to the 401(k) plan are at the Company's discretion and there were no
contributions in 1999.

(13) Business and Credit Concentrations

   In 1998, two customers accounted for 45% of the Company's total revenue, and
47% of trade accounts receivable at December 31, 1998. In 1999, two customers
accounted for 24% of the Company's total revenue, and 13% of trade accounts
receivable at December 31, 1999. For the three months ended March 31, 2000, two
customers accounted for 26% of the Company's total revenue, and 51% of trade
accounts receivable.

(14) Related Party Transactions

   The Company leased certain equipment from a corporation controlled by an
officer of the Company in 1998 and 1999. The leases expire from December 1999
to October 2000. Aggregate lease payments of approximately $29,000 were made in
1998 and 1999. An aggregate payment of approximately $8,000 will be made in
2000.

(15) Subsequent Event-Proposed Business Combination (Unaudited)

   In April 2000, the Company merged with iBEAM Broadcasting Corporation
(iBEAM) in a transaction to be accounted for as a purchase of the Company by
iBEAM. Under the terms of the merger, all issued and outstanding shares of
common and preferred stock and warrants to purchase shares of the Company were
exchanged for approximately 8.2 million shares of series F redeemable
convertible preferred stock of iBEAM which are convertible into common stock of
iBEAM on a share for share basis upon the closing of iBEAM's initial public
offering. In addition, holders of the Company's securities may receive
approximately an additional 1.1 million shares of iBEAM common stock if the
Company meets revenue targets in the twelve months following the acquisition.
Options granted under the Company's 1999 stock option plan were converted into
options to purchase shares of iBEAM's series F redeemable convertible preferred
stock.

Item 14. Indemnification Of Directors And Officers

   Section 145 of the Delaware General Corporation Law permits a corporation
to include in its charter documents, and in agreements between the corporation
and its directors and officers, provisions expanding the scope of
indemnification beyond that specifically provided by the current law.

   Article X of our Amended and Restated Certificate of Incorporation provides
for the indemnification of directors to the fullest extent permissible under
Delaware law.

   Article VI of our Amended and Restated Bylaws provides for the
indemnification of officers, directors and third parties acting on behalf of
us if such person acted in good faith and in a manner reasonably believed to
be in and not opposed to our best interest, and, with respect to any criminal
action or proceeding, the indemnified party had no reason to believe his or
her conduct was unlawful.

   We have entered into indemnification agreements with our directors and
executive officers, in addition to indemnification provided for in our Amended
and Restated Bylaws, and intend to enter into indemnification agreements with
any new directors and executive officers in the future. The indemnification
agreements may require us, among other things, to indemnify our directors and
officers against certain liability that may arise by reason of their status or
service as directors and 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' insurance, if available on reasonable
terms.

Item 15. Recent Sales Of Unregistered Securities

   Since inception, we have issued unregistered securities to a limited number
of persons, as described below. None of these transactions involved any
underwriters, underwriting discounts or commissions, or any public offering,
and we believe that each transaction was exempt from the registration
requirements of the Securities Act by virtue of Section 4(2) thereof,
Regulation D promulgated thereunder or Rule 701 pursuant to compensatory
benefit plans and contracts relating to compensation as provided under such
Rule 701. The recipients of securities 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 us, to information about us.

   (b) Financial Statement Schedules

   Schedules not listed above have been omitted because the information
required to be set forth therein is not applicable or is shown in the
financial statements or notes thereto.

Item 17. Undertakings

   We hereby undertake 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 by us for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of iBEAM pursuant to the provisions referenced in Item 14 of this Registration
Statement or otherwise, we have 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 us of expenses incurred or paid by a director, officer, or
controlling person of iBEAM in the successful defense of any action, suit or
proceeding) is asserted by a director, officer or controlling person in
connection with the securities being registered hereunder, we 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.

   We hereby undertake that:

      (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of Prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of Prospectus filed by iBEAM 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, 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.

<PAGE>

                                  ARTICLE IV

          A.   Classes of Stock.  This corporation is authorized to issue two
               ----------------
classes of stock to be designated, respectively, "Common Stock" and "Preferred

Incorporation was filed pursuant to which each outstanding share of Common Stock
was divided into 1.377 shares of Common Stock.  The total number of shares that
this corporation is authorized to issue is One Hundred and Fifty Two Million
(152,000,000) shares.  One Hundred and Twenty Million (120,000,000) shares shall
be Common Stock and Thirty Two Million (32,000,000) shares shall be Preferred
Stock, each with a par value of $0.0001 per share.  The first series of
Preferred Stock shall be designated "Series A Preferred Stock," consisting of

consisting of Three Million Three Hundred and Eighty Thousand (3,380,000)

          B.   Rights, Preferences and Restrictions of Preferred Stock.  The
               -------------------------------------------------------
Preferred Stock authorized by this Restated Certificate of Incorporation may be
issued from time to time in one or more series.  The rights, preferences,
privileges, and restrictions granted to and imposed on the Series A, Series B,
Series C, Series D, Series E, Series F, Series G and Series H Preferred Stock
are as set forth below in this Article IV(B).  The Board of Directors is hereby
authorized to fix or alter the rights, preferences, privileges and restrictions
granted to or imposed upon additional series of Preferred Stock, and the number
of shares constituting any such series and the designation thereof, or of any of
them.  Subject to compliance with applicable protective voting rights that have
been or may be granted to the Preferred Stock or series thereof in Certificates
of Designation or this corporation's Certificate of Incorporation ("Protective
Provisions"), but notwithstanding any other rights of the Preferred Stock or any
series thereof, the rights, privileges, preferences and restrictions of any such
additional series may be subordinated to, pari passu with (including, without
                                          ---- -----
limitation, inclusion in provisions with respect to liquidation and acquisition
preferences, redemption and/or approval of matters by vote or written consent),
or senior to any of those of any present or future class or series of Preferred
or Common Stock.  Subject to compliance with applicable Protective Provisions,
the Board of Directors is also authorized to increase or decrease the number of
shares of any series (other than the Series A Preferred Stock, Series B
Preferred Stock, Series C Preferred Stock, Series D Preferred Stock, Series E
Preferred Stock, Series F Preferred Stock, Series G or Series H Preferred
Stock), prior or subsequent to the issue of that series, but not below the
number of shares of such series then outstanding.  In case the number of shares
of any series shall be so

                                       2
<PAGE>

decreased, the shares constituting such decrease shall resume the status that
they had prior to the adoption of the resolution originally fixing the number of
shares of such series.

          1.   Dividend Provisions.

shall be entitled to receive dividends, out of any assets legally available
therefor, prior and in preference to any declaration or payment of any dividend

into or entitling the holder thereof to receive, directly or indirectly,
additional shares of Common Stock of this corporation) on the Common Stock of

respective series shall be entitled to receive under this Section 1 upon the
affirmative vote or written consent of the holders of at least a majority of the
Series A, Series B, Series C, Series D, Series E, Series F,  Series G, or Series
H Preferred Stock respectively, then outstanding.

          2.   Liquidation Preference.

Preferred and Series H Stock shall be entitled to receive, prior and in
preference to any distribution of any of the assets of this corporation to the

Series E Issue Price"), plus declared but unpaid dividends on such share
(subject to adjustment of such fixed dollar amounts for any stock splits, stock
dividends, combinations, recapitalizations or the like); (F) $9.9855 for each
outstanding share of Series F Preferred Stock (the "Original Series F Issue
Price"), plus declared but unpaid dividends on such share (subject to adjustment
of such fixed dollar amounts for any stock splits, stock dividends,
combinations, recapitalizations or the like); (G) for each outstanding share of
Series G Preferred Stock, the price to the public per share in this
corporation's initial public offering of common stock pursuant to a Registration
Statement on Form S-1 (the "Original Series G Issue Price"); and (H) for each
outstanding share of Series H Preferred Stock, the price to the public per share
(less the underwriter's discount) in this corporation's initial public offering
of common stock pursuant to a Registration Statement on Form S-1 (the "Original
Series H Issue Price"). If upon the occurrence of such event, the assets and
funds thus distributed among the holders of the Series A, Series B, Series C,
Series D, Series E, Series F, Series G and Series H Preferred Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then, subject to the rights of series of Preferred Stock
that may from time to time come into existence, the entire assets and funds of
this corporation legally available for distribution shall be distributed ratably
among the holders of the Series A, Series B, Series C, Series D, Series E,
Series F,  Series G, and Series H Preferred Stock in proportion to the foregoing
respective liquidation preferences of such holder.

          (b) Upon the completion of the distribution required by subsection (a)
of this Section 2 and any other distribution that may be required with respect
to series of Preferred Stock that may from time to time come into existence, the
remaining assets of this corporation available for distribution to stockholders
shall be distributed among the holders of Series A, Series B, Series C, Series
D, Series E, Series F, Series G and Series H Preferred Stock and Common Stock
pro rata based on the number of shares of Common Stock held by each (assuming
full conversion of all such Series A, Series B, Series C, Series D, Series E,
Series F, Series G and Series H Preferred Stock) until the value of the assets
distributed to or the consideration received by such holders in the aggregate
equals $300,000,000 (including amounts paid pursuant to subsection (a) of this
Section 2);

                                       4
<PAGE>

          (c)  Thereafter, subject to the rights of series of Preferred Stock
that may from time to time come into existence, if assets remain in this
corporation, the holders of the Common Stock of this corporation shall receive
all of the remaining assets of this corporation pro rata based on the number of
shares of Common Stock held by each.

          (d)  (i)   For purposes of this Section 2, a liquidation, dissolution
or winding up of this corporation shall be deemed to be occasioned by, or to
include (unless the holders of at least a majority of the Series A, Series B,
Series C, Series D, Series E,  Series F, Series G and Series H Preferred Stock
then outstanding voting together as a single class shall determine otherwise),
(A) the acquisition of this corporation by another entity by means of any
transaction or series of related transactions (including, without limitation,
any reorganization, merger or consolidation) that results in the transfer of
fifty percent (50%) or more of the outstanding voting power of this corporation
to another person or entity or group of related persons or entities; or (B) a
sale of all or substantially all of the assets of this corporation.

               (ii)  In any of such events, if the consideration received by
this corporation is other than cash, its value will be deemed its fair market
value. Any securities shall be valued as follows:

                     (A) Securities not subject to investment letter or other
similar restrictions on free marketability covered by (B) below:

                         (1) If traded on a securities exchange or through the
Nasdaq National Market, the value shall be deemed to be the average of the
closing prices of the securities on such exchange or system over the thirty (30)
day period ending three (3) days prior to the closing;

                         (2) If actively traded over-the-counter, the value
shall be deemed to be the average of the closing bid or sale prices (whichever
is applicable) over the thirty (30) day period ending three (3) days prior to
the closing; and

                         (3) If there is no active public market, the value
shall be the fair market value thereof, as mutually determined by this
corporation and the holders of at least a majority of the voting power of all
then outstanding shares of Preferred Stock.

                     (B) The method of valuation of securities subject to
investment letter or other restrictions on free marketability (other than
restrictions arising solely by virtue of a stockholder's status as an affiliate
or former affiliate) shall be to make an appropriate discount from the market
value determined as above in (A) (1), (2) or (3) to reflect the approximate fair
market value thereof, as mutually determined by this corporation and the holders
of at least a majority of the voting power of all then outstanding shares of
such Preferred Stock.

               (iii) In the event the requirements of this subsection 2(d) are
not complied with, this corporation shall forthwith either:

                     (A) cause such closing to be postponed until such time as
the requirements of this Section 2 have been complied with; or

                                       5
<PAGE>

                    (B) cancel such transaction, in which event the rights,
preferences and privileges of the holders of the Series A, Series B, Series C,
Series D, Series E, Series F, Series G and Series H Preferred Stock shall revert
to and be the same as such rights, preferences and privileges existing
immediately prior to the date of the first notice referred to in subsection
2(d)(iv) hereof.

               (iv) This corporation shall give each holder of record of Series
A, Series B, Series C, Series D, Series E, Series F, Series G and Series H
Preferred Stock written notice of such impending transaction not later than
twenty (20) days prior to the stockholders' meeting called to approve such
transaction, or twenty (20) days prior to the closing of such transaction,
whichever is earlier, and shall also notify such holders in writing of the final
approval of such transaction. The first of such notices shall describe the
material terms and conditions of the impending transaction and the provisions of
this Section 2, and this corporation shall thereafter give such holders prompt
notice of any material changes. The transaction shall in no event take place
sooner than twenty (20) days after this corporation has given the first notice
provided for herein or sooner than ten (10) days after this corporation has
given notice of any material changes provided for herein; provided, however,
that such periods may be shortened upon the written consent of the holders of
Preferred Stock that are entitled to such notice rights or similar notice rights
and that represent at least a majority of the voting power of all then
outstanding shares of such Preferred Stock.

          3.   Conversion.  The holders of the Series A, Series B, Series C,
               ----------
Series D, Series E, Series F, Series G and Series H Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):

          (a)  Right to Convert.  Subject to Section 3(d), each share of Series
               ----------------
A, Series B, Series C, Series D, Series E, Series F, Series G and Series H
Preferred Stock shall be convertible, at the option of the holder thereof, at
any time after the date of issuance of such share, at the office of this
corporation or any transfer agent for such stock, into such number of fully paid
and nonassessable shares of Common Stock as is determined by (i) in the case of
the Series A Preferred Stock, dividing the Original Series A Issue Price by the
Conversion Price applicable to such share, determined as hereafter provided, in
effect on the date the certificate is surrendered for conversion; (ii) in the
case of the Series B Preferred Stock, dividing the Original Series B Issue Price
by the Conversion Price applicable to such share, determined as hereafter
provided, in effect on the date the certificate is surrendered for conversion;
(iii) in the case of the Series C Preferred Stock, dividing the Original Series
C Issue Price by the Conversion Price applicable to such share, determined as
hereafter provided, in effect on the date the certificate is surrendered for
conversion; (iv) in the case of the Series D Preferred Stock, dividing the
Original Series D Issue Price by the Conversion Price applicable to such share,
determined as hereafter provided, in effect on the date the certificate is
surrendered for conversion; (v) in the case of the Series E Preferred Stock,
dividing the Original Series E Issue Price by the Conversion Price applicable to
such share, determined as hereafter provided, in effect on the date the
certificate is surrendered for conversion; (vi) in the case of Series F
Preferred Stock, by dividing the Original Series F Issue Price by the Conversion
Price applicable to such share, determined as provided hereafter, in effect on
the date the certificate is surrendered for conversion; (vii) in the case of
Series G Preferred Stock, by dividing the Original Series G Issue Price by the
Conversion Price applicable to such share, determined as provided hereafter, in
effect on the date the certificate is

                                       6
<PAGE>

surrendered for conversion; and (viii) in the case of Series H Preferred Stock,
by dividing the Original Series H Issue Price by the Conversion Price applicable
to such share, determined as provided hereafter, in effect on the date the
certificate is surrendered for conversion The initial Conversion Price per share
for shares of Series A, Series B, Series C, Series D, Series E, Series F, Series
G and Series H Preferred Stock shall be the Original Series A Issue Price,
Original Series B Issue Price, Original Series C Issue Price, Original Series D
Issue Price, Original Series E Issue Price, Original Series F Issue Price,
Original Series G Issue Price, and Original Series H Issue Price, respectively;
provided, however, that the Conversion Price for the Series A, Series B, Series
C, Series D, Series E, Series F, Series G and Series H Preferred Stock shall be
subject to adjustment from time to time as set forth in subsection 3(d). As of
the filing of this Restated Certificate of Incorporation, the Conversion Prices
for Series A-F Preferred Stock shall be equal to approximately (A) $0.2905 for
each outstanding share of Series A Preferred Stock; (B) $0.3994 for each
outstanding share of Series B Preferred Stock; (C) $0.8279 for each outstanding
share of Series C Preferred Stock; (D) $1.4427 for each outstanding share of
Series D Preferred Stock; (E) $9.9855 for each outstanding share of Series E
Preferred Stock; and (F) $9.9855 for each outstanding share of Series F
Preferred Stock (subject to further adjustment from time to time as set forth in
subsection 3(d)). There shall be no such adjustment to the Conversion Price of
Series G-H Preferred Stock, except as provided in Section 3(d).

          (b)  Automatic Conversion. Each share of Series A, Series B, Series C,
               --------------------
Series D, Series E, Series F, Series G and Series H Preferred Stock shall
automatically be converted into shares of Common Stock at the Conversion Price
at the time in effect for such Series A, Series B, Series C, Series D, Series E,
Series F, Series G or Series H Preferred Stock immediately upon the earlier of
(i) this corporation's sale of its Common Stock in a firm commitment
underwritten public offering pursuant to a registration statement on Form S-1 or
Form SB-2 under the Securities Act of 1933, as amended, the public offering
price of which was not less than $2.88 per share (as adjusted for any stock
splits, stock dividends, recapitalizations or the like) and $20,000,000 in the
aggregate or (ii) the date specified by written consent or agreement of the
holders of a majority of the then outstanding shares of Series A, Series B,
Series C, Series D, Series E, Series F, Series G and Series H Preferred Stock,
voting together as a single class.

          (c)  Mechanics of Conversion.  Except as provided in Section 3(b),
               -----------------------
before any holder of Series A, Series B, Series C, Series D, Series E, Series F,
Series G or Series H Preferred Stock shall be entitled to convert the same into
shares of Common Stock, he or she shall surrender the certificate or
certificates therefor, duly endorsed, at the office of this corporation or of
any transfer agent for the Series A, Series B, Series C, Series D, Series E,
Series F, Series G, or Series H Preferred Stock, and shall give written notice
to this corporation at its principal corporate office, of the election to
convert the same and shall state therein the name or names in which the
certificate or certificates for shares of Common Stock are to be issued.  This
corporation shall, as soon as practicable thereafter, issue and deliver at such
office to such holder of Series A, Series B, Series C, Series D, Series E,
Series F, Series G or Series H Preferred Stock, or to the nominee or nominees of
such holder, a certificate or certificates for the number of shares of Common
Stock to which such holder shall be entitled as aforesaid.  Such conversion
shall be deemed to have been made immediately prior to the close of business on
the date of such surrender of the shares of Series A, Series B, Series C, Series
D, Series E, Series F, Series G or Series H Preferred Stock to be converted, and
the person or persons entitled to

                                       7
<PAGE>

receive the shares of Common Stock issuable upon such conversion shall be
treated for all purposes as the record holder or holders of such shares of
Common Stock as of such date. If the conversion is in connection with an
underwritten offering of securities registered pursuant to the Securities Act of
1933, the conversion may, at the option of any holder tendering Series A, Series
B, Series C, Series D, Series E, Series F, Series G or Series H Preferred Stock
for conversion, be conditioned upon the closing with the underwriters of the
sale of securities pursuant to such offering, in which event the persons
entitled to receive the Common Stock upon conversion of the Series A, Series B,
Series C, Series D, Series E, Series F, Series G or Series H Preferred Stock
shall not be deemed to have converted such Series A, Series B, Series C, Series
D, Series E, Series F, Series G, or Series H Preferred Stock until immediately
prior to the closing of such sale of securities.

          (d)  Conversion Price Adjustments of Preferred Stock for Certain
               -----------------------------------------------------------
Dilutive Issuances, Splits and Combinations.  The Conversion Price of the Series
- -------------------------------------------
A, Series B, Series C, Series D, Series E, Series F, Series G and Series H
Preferred Stock shall be subject to adjustment from time to time as follows:

               (i)  (A)  If this corporation shall issue, after the date upon
which any shares of Series A, Series B, Series C, Series D, Series E, Series F,
Series G, or Series H Preferred Stock were first issued (the "Purchase Date"
with respect to such series), any Additional Stock (as defined below) without
consideration or for a consideration per share less than the Conversion Price
for such series in effect immediately prior to the issuance of such Additional
Stock, the Conversion Price for such series in effect immediately prior to each
such issuance shall forthwith (except as otherwise provided in this clause (i))
be adjusted to a price determined by multiplying such Conversion Price by a
fraction, the numerator of which shall be the number of shares of Common Stock
outstanding immediately prior to such issuance (including shares of Common Stock
deemed to be issued pursuant to subsection 3(d)(i)(E)(1) or (2)) plus the number
of shares of Common Stock that the aggregate consideration received by this
corporation for such issuance would purchase at such Conversion Price; and the
denominator of which shall be the number of shares of Common Stock outstanding
immediately prior to such issuance (including shares of Common Stock deemed to
be issued pursuant to subsection 3(d)(i)(E)(1) or (2)) plus the number of shares
of such Additional Stock. There shall be no adjustment to the Conversion Price
of the Series G Preferred Stock due to the issuance of the Series H Preferred
Stock.

                    (B)  No adjustment of the Conversion Price for the Series A,
Series B, Series C, Series D, Series E, Series F, Series G, or Series H
Preferred Stock shall be made in an amount less than one cent per share,
provided that any adjustments that are not required to be made by reason of this
sentence shall be carried forward and shall be either taken into account in any
subsequent adjustment made prior to three (3) years from the date of the event
giving rise to the adjustment being carried forward, or shall be made at the end
of three (3) years from the date of the event giving rise to the adjustment
being carried forward. Except to the limited extent provided for in subsections
(E)(3) and (E)(4), no adjustment of such Conversion Price pursuant to this
subsection 3(d)(i) shall have the effect of increasing the Conversion Price
above the Conversion Price in effect immediately prior to such adjustment.

                                       8
<PAGE>

                    (C) In the case of the issuance of Common Stock for cash,
the consideration shall be deemed to be the amount of cash paid therefor before
deducting any reasonable discounts, commissions or other expenses allowed, paid
or incurred by this corporation for any underwriting or otherwise in connection
with the issuance and sale thereof.

                    (D) In the case of the issuance of the Common Stock for a
consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair value thereof as determined by the Board of
Directors irrespective of any accounting treatment.

                    (E) In the case of the issuance (whether before, on or after
the applicable Purchase Date) of options to purchase or rights to subscribe for
Common Stock, securities by their terms convertible into or exchangeable for
Common Stock or options to purchase or rights to subscribe for such convertible
or exchangeable securities, the following provisions shall apply for all
purposes of this subsection 3(d)(i) and subsection 3(d)(ii):

                        (1) The aggregate maximum number of shares of Common
Stock deliverable upon exercise of such options to purchase or rights to
subscribe for Common Stock shall be deemed to have been issued at the time such
options or rights were issued and for a consideration equal to the consideration
(determined in the manner provided in subsections 3(d)(i)(C) and (d)(i)(D)), if
any, received by this corporation upon the issuance of such options or rights
plus the minimum exercise price provided in such options or rights (without
taking into account potential antidilution adjustments) for the Common Stock
covered thereby.

                        (2) The aggregate maximum number of shares of Common
Stock deliverable upon conversion of, or in exchange for, any such convertible
or exchangeable securities or upon the exercise of options to purchase or rights
to subscribe for such convertible or exchangeable securities and subsequent
conversion or exchange thereof shall be deemed to have been issued at the time
such securities were issued or such options or rights were issued and for a
consideration equal to the consideration, if any, received by this corporation
for any such securities and related options or rights (excluding any cash
received on account of accrued interest or accrued dividends), plus the minimum
additional consideration, if any, to be received by this corporation (without
taking into account potential antidilution adjustments) upon the conversion or
exchange of such securities or the exercise of any related options or rights
(the consideration in each case to be determined in the manner provided in
subsections 3(d)(i)(C) and (d)(i)(D)).

                        (3) In the event of any change in the number of shares
of Common Stock deliverable or in the consideration payable to this corporation
upon exercise of such options or rights or upon conversion of or in exchange for
such convertible or exchangeable securities, including, but not limited to, a
change resulting from the antidilution provisions thereof (unless such options
or rights or convertible or exchangeable securities were merely deemed to be
included in the numerator and denominator for purposes of determining the number
of shares of Common Stock outstanding for purposes of subsection 3(d)(i)(A)),
the Conversion Price of the Series A, Series B, Series C, Series D, Series E,
the Series F, the Series G and the Series H Preferred Stock, to the extent in
any way affected by or computed using such

                                       9
<PAGE>

options, rights or securities, shall be recomputed to reflect such change, but
no further adjustment shall be made for the actual issuance of Common Stock or
any payment of such consideration upon the exercise of any such options or
rights or the conversion or exchange of such securities.

                        (4) Upon the expiration of any such options or rights,
the termination of any such rights to convert or exchange or the expiration of
any options or rights related to such convertible or exchangeable securities,
the Conversion Price of the Series A, Series B, Series C, Series D, Series E,
Series F, Series G, or Series H Preferred Stock, to the extent in any way
affected by or computed using such options, rights or securities or options or
rights related to such securities (unless such options or rights were merely
deemed to be included in the numerator and denominator for purposes of
determining the number of shares of Common Stock outstanding for purposes of
subsection 3(d)(i)(A)), shall be recomputed to reflect the issuance of only the
number of shares of Common Stock (and convertible or exchangeable securities
that remain in effect) actually issued upon the exercise of such options or
rights, upon the conversion or exchange of such securities or upon the exercise
of the options or rights related to such securities.

                        (5) The number of shares of Common Stock deemed issued
and the consideration deemed paid therefor pursuant to subsections 3(d)(i)(E)(1)
and (2) shall be appropriately adjusted to reflect any change, termination or
expiration of the type described in either subsection 3(d)(i)(E)(3) or (4).

               (ii) "Additional Stock" shall mean any shares of Common Stock
issued (or deemed to have been issued pursuant to subsection 3(d)(i)(E)) by this
corporation after the Purchase Date other than:

                    (A) Common Stock issued pursuant to a transaction described
in subsection 3(d)(iii) hereof;

                    (B) Common Stock (or options therefor) issuable or issued to
employees, consultants, directors or vendors (if in transactions with primarily
non-financing purposes) of this corporation, with the approval of a majority of
the members of the Board of Directors not holding management positions with the
Company, directly or pursuant to a stock option plan or restricted stock plan
approved by the Board of Directors of this corporation (and the reissuance of
any shares issued or subject to outstanding options returned to the Company from
any unexercised options or restricted stock repurchased by the Company after
such date); or

                    (C) the issuance of stock, warrants or other securities or
rights, with the approval of a majority of the Board of Directors of the
Company, to persons or entities in connection with a bona fide business
acquisition of or by the Company, whether by merger, consolidation, sale of
assets, sale or exchange of stock or otherwise; or

                    (D) the issuance of stock warrants or other securities or
rights, with the approval of a majority of the Board of Directors of the
Company, to persons with which the Company is entering or has entered into a
strategic relationship; or

                                       10
<PAGE>

                    (E) the issuance of stock, warrants or other securities or
rights in connection with bank and other debt financings, commercial lending,
equipment financings, capital lease, or similar transactions approved by a
majority of the Board of Directors of this corporation;

                    (F) in the event that Intel Corporation and the Company
agree on the terms of a technology development relationship, the issuance of a
warrant to Intel Corporation to purchase up to 146,199 shares of Series C
Preferred Stock for $3.42 per share (subject to adjustment of such fixed dollar
amounts for any stock splits, stock dividends, combinations, recapitalizations
or the like) and the issuance of any Common Stock in connection with the
conversion of such preferred stock;

                    (G) the issuance of a warrant to Comdisco Inc. to purchase
up to 6,397 shares of Series D Preferred Stock for $4.69 per share (subject to
adjustment of such fixed dollar amounts for any stock splits, stock dividends,
combinations, recapitalizations or the like) and the issuance of any Common
Stock in connection with the conversion of such preferred stock;

                    (H) the issuance of a warrant to America Online to purchase
$5 million of Common Stock of the Company at an exercise price equal to the
price to public in the Company's initial public offering of Common Stock, less
underwriting discounts and commissions.

              (iii) In the event this corporation should at any time or from
time to time after the Purchase Date fix a record date for the effectuation of a
split or subdivision of the outstanding shares of Common Stock or the
determination of holders of Common Stock entitled to receive a dividend or other
distribution payable in additional shares of Common Stock or other securities or
rights convertible into, or entitling the holder thereof to receive directly or
indirectly, additional shares of Common Stock (hereinafter referred to as
"Common Stock Equivalents") without payment of any consideration by such holder
for the additional shares of Common Stock or the Common Stock Equivalents
(including the additional shares of Common Stock issuable upon conversion or
exercise thereof), then, as of such record date (or the date of such dividend
distribution, split or subdivision if no record date is fixed), the Conversion
Price of the Series A, Series B, Series C, Series D, Series E, Series F, Series
G, or Series H Preferred Stock shall be appropriately decreased so that the
number of shares of Common Stock issuable on conversion of each share of such
series shall be increased in proportion to such increase of the aggregate of
shares of Common Stock outstanding and those issuable with respect to such
Common Stock Equivalents.

              (iv)  If the number of shares of Common Stock outstanding at any
time after the Purchase Date is decreased by a combination of the outstanding
shares of Common Stock, then, following the record date of such combination, the
Conversion Price for the Series A, Series B, Series C, Series D, Series E,
Series F, Series G and Series H Preferred Stock shall be appropriately increased
so that the number of shares of Common Stock issuable on conversion of each
share of such series shall be decreased in proportion to such decrease in
outstanding shares.

                                       11
<PAGE>

          (e)  Other Distributions.  In the event this corporation shall declare
               -------------------
a distribution payable in securities of other persons, evidences of indebtedness
issued by this corporation or other persons, assets (excluding cash dividends)
or options or rights not referred to in subsection 3(d)(iii), then, in each such
case for the purpose of this subsection 3(e), the holders of the Series A,
Series B, Series C, Series D, Series E, Series F, Series G and Series H
Preferred Stock shall be entitled to a proportionate share of any such
distribution as though they were the holders of the number of shares of Common
Stock of this corporation into which their shares of Series A, Series B, Series
C, Series D, Series E, Series F, Series G and/or Series H Preferred Stock are
convertible as of the record date fixed for the determination of the holders of
Common Stock of this corporation entitled to receive such distribution.

          (f)  Recapitalizations.  If at any time or from time to time there
               -----------------
shall be a recapitalization of the Common Stock (other than a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 3 or Section 2) provision shall be made so that the holders of the
Series A, Series B, Series C, Series D, Series E, Series F,  Series G and Series
H Preferred Stock shall thereafter be entitled to receive upon conversion of the
Series A, Series B, Series C, Series D, Series E, Series F, Series G or Series H
Preferred Stock, the number of shares of stock or other securities or property
of the Corporation or otherwise, to which a holder of Common Stock deliverable
upon conversion would have been entitled on such recapitalization.  In any such
case, appropriate adjustment shall be made in the application of the provisions
of this Section 3 with respect to the rights of the holders of the Series A,
Series B, Series C, Series D, Series E, Series F, Series G and Series H
Preferred Stock after the recapitalization to the end that the provisions of
this Section 3 (including adjustment of the Conversion Price then in effect and
the number of shares purchasable upon conversion of the Series A, Series B,
Series C, Series D, Series E, Series F Series G and Series H Preferred Stock)
shall be applicable after that event as nearly equivalent as may be practicable.

          (g)  No Impairment.  This corporation will not, by amendment of its
               -------------

transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms to be observed or performed hereunder by this
corporation, but will at all times in good faith assist in the carrying out of

               (i) No fractional shares shall be issued upon the conversion of
any share or shares of the Series A, Series B, Series C, Series D, Series E,
Series F, Series G or Series H Preferred Stock and the number of shares of

time of any holder of Series A, Series B, Series C, Series D, Series E, Series
F, Series G or Series H Preferred Stock, furnish or cause to be furnished to
such holder a like certificate setting forth (A) such adjustment and
readjustment, (B) the Conversion Price for such series of Preferred Stock at the
time in effect, and (C) the number of shares of Common Stock and the amount, if
any, of other property that at the time would be received upon the conversion of
a share of Series A, Series B, Series C, Series D, Series E, Series F, Series G

          (i)  Notices of Record Date.  In the event of any taking by this
               ----------------------

purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class or
any other securities or property, or to receive any other right, this

shares of Common Stock, solely for the purpose of effecting the conversion of
the shares of the Series A, Series B, Series C, Series D, Series E, Series F,

as shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series A, Series B, Series C, Series D, Series E,
Series F, Series G and Series H Preferred Stock; and if at any time the number
of authorized but unissued shares of Common Stock shall not be sufficient to
effect the conversion of all then outstanding shares of the Series A, Series B,
Series C, Series D, Series E, Series F, Series G and Series H Preferred Stock,
in addition to such other remedies as shall be available to the holder of such
Preferred Stock, this corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purposes, including, without limitation, engaging in best efforts to obtain the
requisite stockholder approval of any necessary amendment to this certificate.

          (k)  Notices.  Any notice required by the provisions of this Section 3

nearest whole number (with one-half being rounded upward).

               (i)   As long as at least a majority of the shares of Series A

Common Stock basis.

          In the case of any vacancy (other than a vacancy caused by removal) in
the office of a director occurring among the directors elected by the holders of
a class or series of stock pursuant to this Section 4(b), the remaining
directors so elected by that class or series may by affirmative vote of a
majority thereof (or the remaining director so elected if there be but one, or
if there are no such directors remaining, by the affirmative vote of the holders
of a majority of the shares of that class or series), elect a successor or
successors to hold office for the unexpired term of the director or directors
whose place or places shall be vacant.  Any director who shall have been elected
by the holders of a class or series of stock or by any directors so elected as
provided in the immediately preceding sentence hereof may be removed during the
aforesaid term of office, either with or without cause, by, and only by, the
affirmative vote of the holders of the shares of the class or series of stock
entitled to elect such director or directors, given either at a special meeting
of such stockholders duly called for that purpose or pursuant to a written
consent of stockholders, and any vacancy thereby created may be filled by the
holders of that class or series of stock represented at the meeting or pursuant
to unanimous written consent.

               1.2  Request for Registration.
                    ------------------------

                    (a)  Subject to the conditions of this Section 1.2, if the
Company shall receive at any time after the earlier of (i) February 2, 2003 or
(ii) six (6) months after the effective date of the Initial Offering, a written
request is received from the Holders of thirty percent (30%) or more of the
Registrable Securities then outstanding (the "Initiating Holders") that the
Company file a registration statement under the Act covering the registration of
Registrable Securities with an anticipated aggregate offering price of at least
$10,000,000, then the Company shall, within twenty (20) days of the receipt
thereof, give written notice of such request to all Holders, and subject to the
limitations of this Section 1.2, use all reasonable efforts to effect, as soon
as practicable, the registration under the Act of all Registrable Securities
that the Holders request to be registered in a written request received by the
Company within twenty (20) days of the mailing of the Company's notice pursuant
to this Section 1.2(a).

                    (b)  If the Initiating Holders intend to distribute the
Registrable Securities covered by their request by means of an underwriting,
they shall so advise the Company as a part of their request made pursuant to
this Section 1.2 and the Company shall include such information in the written
notice referred to in Section 1.2(a). In such event the right of any Holder to
include its Registrable Securities in such 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 enter into an underwriting agreement in
customary form with the underwriter or underwriters selected for such
underwriting by the Company (which underwriter or underwriters shall be
reasonably acceptable to a majority in interest of the Initiating Holders).
Notwithstanding any other provision of this Section 1.2, if the underwriter
advises the Company that marketing factors require a limitation of the number of
securities underwritten (including Registrable Securities), then the Company
shall so advise all Holders of Registrable Securities that would otherwise be
underwritten pursuant hereto, and the number of shares that may be included in
the underwriting shall be allocated to the Holders of such Registrable
Securities on a pro rata basis based on the number of Registrable Securities
held by all such Holders (including the Initiating Holders). Any Registrable
Securities excluded or withdrawn from such underwriting shall be withdrawn from
the registration.

                    (c)  The Company shall not be required to effect a
registration pursuant to this Section 1.2:

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

                         (ii)  after the Company has effected two (2)
registrations pursuant to this Section 1.2, and such registrations have been
declared or ordered effective and the securities offered pursuant to such
registrations have been sold; or

                                      -3-
<PAGE>

                         (iii) during the period starting with the date sixty
(60) days prior to the Company's good faith estimate of the date of the filing
of, and ending on a date one hundred eighty (180) days following the effective
date of, a Company-initiated registration subject to Section 1.3 below, provided
that the Company is actively employing in good faith all reasonable efforts to
cause such registration statement to become effective; or

                         (iv)  if the Initiating Holders propose to dispose of
Registrable Securities that may be registered on Form S-3 pursuant to Section
1.4 hereof; or

                         (v)   if the Company shall furnish to Holders
requesting a registration statement pursuant to this Section 1.2, a certificate
signed by the Company's Chief Executive Officer or Chairman of the Board 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 stockholders for such
registration statement to be effected at such time, in which event the Company
shall have the right to defer such filing for a period of not more than one
hundred twenty (120) days after receipt of the request of the Initiating
Holders, provided that such right to delay a request shall be exercised by the
Company not more than once in any twelve (12)-month period.

               1.3  Company Registration.
                    --------------------

                    (a)  If (but without any obligation to do so) the Company
proposes to register (including for this purpose a registration effected by the
Company for stockholders other than the Holders) any of its stock or other
securities under the Act in connection with the public offering of such
securities (other than a registration relating solely to the sale of securities
to participants in a Company stock plan, a registration relating to a corporate
reorganization or other transaction under Rule 145 of the Act, a registration on
any form that 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, a registration in which the only Common Stock being
registered is Common Stock issuable upon conversion of debt securities that are
also being registered, a registration in which the only Common Stock being
registered is Common Stock issuable pursuant to warrants issued in connection
with the issuance of debt securities, or a registration relating solely to
securities not convertible into Common Stock), the Company shall, at such time,
promptly give each Holder written notice of such registration. Upon the written
request of each Holder given within twenty (20) days (or within ten (10) days if
the notice is given after the Company has completed its Initial Offering) after
mailing of such notice by the Company in accordance with Section 4.5, the
Company shall, subject to the provisions of Section 1.3(c), use all reasonable
efforts to cause to be registered under the Act all of the Registrable
Securities that each such Holder has requested to be registered.

                    (b)  Right to Terminate Registration. The Company shall have
                         -------------------------------
the right to terminate or withdraw any registration initiated by it under this
Section 1.3 prior to the effectiveness of such registration whether or not any
Holder has elected to include securities in such registration. The expenses of
such withdrawn registration shall be borne by the Company in accordance with
Section 1.7 hereof.

                                      -4-
<PAGE>

                    (c)  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 this Section 1.3 to include any of the
Holders' securities in such underwriting unless they accept the terms of the
underwriting as agreed upon between the Company and the underwriters selected by
it (or by other persons entitled to select the underwriters) and enter into an
underwriting agreement in customary form with an underwriter or underwriters
selected by the Company, and then only in such quantity as the managing
underwriter determines in its sole discretion will not jeopardize the success of
the offering by the Company. If the total amount of securities, including
Registrable Securities, requested by stockholders to be included in such
offering exceeds the amount of securities sold other than by the Company 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,
that the underwriters determine in their sole discretion will not jeopardize the
success of the offering (the securities so included to be apportioned pro rata
among the selling Holders according to the total amount of securities entitled
to be included therein owned by each selling Holder or in such other proportions
as shall mutually be agreed to by such selling Holders), but in no event shall
(i) the amount of securities of the selling Holders included in the offering be
reduced below twenty percent (20%) of the total amount of securities included in
such offering, unless such offering is the initial public offering of the
Company's securities, in which case the selling Holders may be excluded if the
underwriters make the determination described above and no other stockholder's
securities are included, or (ii) notwithstanding (i) above, any shares being
sold by a stockholder exercising a demand registration right similar to that
granted in Section 1.2 be excluded from such offering. For purposes of the
preceding parenthetical concerning apportionment, for any selling stockholder
that is a Holder of Registrable Securities and that is a partnership or
corporation, the partners, retired partners and stockholders 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 "selling Holder," and any pro rata reduction with respect to such
"selling Holder" shall be based upon the aggregate amount of Registrable
Securities owned by all such related entities and individuals.

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

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

                    (b)  use all reasonable efforts to effect, as soon as
practicable, 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 Holders' Registrable Securities as are specified
in such request, together with all or such portion of the Registrable Securities
of any other 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

                                      -5-
<PAGE>

shall not be obligated to effect any such registration, qualification or
compliance, pursuant to this Section 1.4:

                         (i)    if Form S-3 is not available for such offering
by the Holders;

                         (ii)   if the Holders, together with the holders of any
other securities of the Company entitled to inclusion in such registration,
propose to sell Registrable Securities and such other securities (if any) at an
aggregate price to the public (net of any underwriters' discounts or
commissions) of less than $1,000,000;

                         (iii)  if the Company shall furnish to the Holders a
certificate signed by the Chief Executive Officer or Chairman of the Board of
the Company stating that in the good faith judgment of the Board of Directors of
the Company, it would be seriously detrimental to the Company and its
stockholders 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 one hundred twenty (120)
days after receipt of the request of the Holder or Holders under this Section
1.4; provided, however, that the Company shall not utilize this right more than
once in any twelve month period;

                         (iv)   if the Company has, within the twelve (12) month
period preceding the date of such request, already effected one registration on
Form S-3 for the Holders pursuant to this Section 1.4; or

                         (v)    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.

                    (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 Holders. Registrations effected pursuant to this
Section 1.4 shall not be counted as requests for registration effected pursuant
to Sections 1.2.

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

                    (a)  prepare and file with the SEC a registration statement
with respect to such Registrable Securities and use all reasonable efforts to
cause such registration statement to become effective, and, upon the request of
the Holders of a majority of the Registrable Securities registered thereunder,
keep such registration statement effective for a period of up to one hundred
twenty (120) days or, if earlier, until the distribution contemplated in the
Registration Statement has been completed;

                                      -6-
<PAGE>

                    (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 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 all reasonable 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;

                    (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;

                    (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 or the happening of any event as a result
of which the prospectus included in such registration statement, as then in
effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading in the light of the circumstances then existing;

                    (g)  cause all such Registrable Securities registered
pursuant hereunder to be listed on each securities exchange on which similar
securities issued by the Company are then listed; and

                    (h)  provide a transfer agent and registrar for all
Registrable Securities registered pursuant hereunder and a CUSIP number for all
such Registrable Securities, in each case not later than the effective date of
such registration.

               1.6  Information from Holder.  It shall be a condition precedent
                    -----------------------
to the obligations of the Company to take any action pursuant to this Section 1
with respect to the Registrable Securities of any selling Holder that such
Holder shall furnish to the Company such information regarding itself, the
Registrable Securities held by it, and the intended method of disposition of
such securities as shall be required to effect the registration of such Holder's
Registrable Securities.

               1.7  Expenses of Registration.  All expenses other than
                    ------------------------
underwriting discounts and commissions incurred in connection with
registrations, filings or qualifications pursuant to Sections 1.2, 1.3 and 1.4,
including (without limitation) all registration, filing and

                                      -7-
<PAGE>

qualification fees, printers' and accounting fees, fees and disbursements of
counsel for the Company and for one special counsel for the Holders (which shall
not exceed $20,000) shall be borne by the Company. Notwithstanding the
foregoing, 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 pro rata based upon the number of Registrable
Securities that were to be requested in the withdrawn registration). Unless
otherwise stated, all selling expenses incurred in connection with a
registration relating to securities registered on behalf of the Holders shall be
borne pro rata by the Holder or Holders based on the number of shares so
registered.

               1.8  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.

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

                    (a)  To the extent permitted by law, the Company will
indemnify and hold harmless each Holder, the partners or officers, directors and
stockholders of each Holder, legal counsel and accountants for 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 any state
securities laws, insofar as such losses, claims, damages, or liabilities (or
actions in respect thereof) arise out of or are based upon any of the following
statements, omissions or violations (collectively a "Violation"): (i) any untrue
statement or alleged untrue statement of a material fact contained in such
registration statement, including any preliminary prospectus or final prospectus
contained therein or any amendments or supplements thereto, (ii) the omission or
alleged omission to state therein a material fact required to be stated therein,
or necessary to make the statements therein not misleading, or (iii) any
violation or alleged violation by the Company of the Act, the 1934 Act, any
state securities laws or any rule or regulation promulgated under the Act, the
1934 Act or any state securities laws; and the Company will reimburse each such
Holder, underwriter or controlling person for any legal or other expenses
reasonably incurred by them in connection with investigating or defending any
such loss, claim, damage, liability or action; provided, however, that the
indemnity agreement contained in this subsection 1.9(a) shall not apply to
amounts paid in settlement of any such loss, claim, damage, liability or action
if such settlement is effected without the consent of the Company (which consent
shall not be unreasonably withheld), nor shall the Company be liable 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 that 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;
provided further, however, that the foregoing indemnity agreement with respect
to any preliminary prospectus shall not inure to the benefit of any Holder or
underwriter, or any person controlling such Holder or underwriter, from whom the
person asserting any such losses, claims, damages or liabilities

                                      -8-
<PAGE>

purchased shares in the offering, if a copy of the prospectus (as then amended
or supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of such Holder or
underwriter to such person, if required by law so to have been delivered, at or
prior to the written confirmation of the sale of the shares to such person, and
if the prospectus (as so amended or supplemented) would have cured the defect
giving rise to such loss, claim, damage or liability; provided that the failure
of such Holder to deliver any such prospectus or supplement is not a result of
the Company to meet its obligations under Section 1.5 hereof.

                    (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, legal counsel and
accountants for the Company, 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 any state securities laws, 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 reimburse any person intended
to be indemnified pursuant to this subsection l.9(b), for any legal or other
expenses reasonably incurred by such person in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this subsection l.9(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 l.9(b) exceed the gross proceeds from the
offering received by such Holder.

                    (c) Promptly after receipt by an indemnified party under
this Section 1.9 of notice of the commencement of any action (including any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made against any indemnifying party under this Section 1.9, 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 that may be represented without
conflict by one counsel) shall have the right to retain one separate counsel,
with the fees and expenses to be paid by the indemnifying party, if
representation of such indemnified party by the counsel retained by the
indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such
counsel in such proceeding. The failure to deliver written notice to the
indemnifying party within a reasonable time of the commencement of any such
action, if prejudicial to its ability to defend such action, shall relieve such
indemnifying party of any liability to the indemnified party under this Section
1.9, 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 1.9.

                                      -9-
<PAGE>

                    (d) If the indemnification provided for in this Section 1.9
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
herein, 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. 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 1.9 shall survive the completion of any offering of Registrable
Securities in a registration statement under this Section 1, and otherwise.

           1.10     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 Initial Offering;

                    (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 that permits the
selling of any such securities without registration or pursuant to such form.

           1.11     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 that (i) is a subsidiary, parent, affiliate (as such
term is defined in Rule 405 promulgated under the Act) partner, limited partner,
retired partner or stockholder (collectively, "Related Person") of a Holder,
(ii) is a Holder's family member or trust for the benefit of an individual
Holder, or (iii) after such assignment or transfer, holds at least 413,100
shares of Registrable Securities (subject to appropriate adjustment for stock
splits, stock dividends, combinations and other recapitalizations), provided:
(a) the Company is, within a reasonable time after such transfer, furnished with
written notice of the name and address of such transferee or assignee and the
securities with respect to which such registration rights are being assigned;
(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 1.13 below; and (c) such assignment shall be effective
only if immediately following such transfer the further disposition of such
securities by the transferee or assignee is restricted under the Act.

           1.12     Limitations on Subsequent Registration Rights.  From and
                    ---------------------------------------------
after the date of this Agreement, the Company shall not, without the prior
written consent of the Holders of a majority of the Registrable Securities,
enter into any agreement with any holder or prospective holder of any securities
of the Company that would allow such holder or prospective holder (a) to include
such securities in any registration filed under Section 1.3 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
such securities will not reduce the amount of the Registrable Securities of the
Holders that are included or (b) to demand registration of their securities.

           1.13      Stand-Off" Agreement. Each Holder hereby agrees that it
                     --------------------
will not, without the prior written consent of the managing underwriter and the
Company, during the period commencing on the date of the final prospectus
relating to the Company's initial public offering and ending on the date
specified by the Company and the managing underwriter (such period not to exceed
one hundred eighty (l80) days) (i) lend, offer, pledge, sell, contract to sell,
sell any option or contract to purchase, purchase any option or contract to
sell, grant any option, right or warrant to purchase, or otherwise transfer or
dispose of, directly or indirectly, any shares of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock (whether such
shares or any such securities are then owned by the Holder or are thereafter
acquired), or (ii) enter into any swap or other arrangement that transfers to
another, in whole or in part, any of the economic consequences of ownership of
the Common Stock, whether any such transaction described in clause (i) or (ii)
above is to be settled by delivery of Common Stock or such other securities, in
cash or otherwise. The underwriters in connection with the Company's initial
public offering are intended third party beneficiaries of this Section 1.13 and
shall have the right, power and authority to enforce the provisions hereof as
though they were a party hereto.

       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.  However,

                                     -11-
<PAGE>

nothing in this Section 1.13 shall affect, impair or diminish any Holder's right
to sell, transfer or assign any or all of its shares of Registrable Securities
to a Related Person pursuant to the terms set forth in Section 1.11 hereof.

          1.14      Termination of Registration Rights.  No Holder shall be
                    ----------------------------------
entitled to exercise any right provided for in this Section 1 after five (5)
years following the consummation of the Initial Offering or, as to any Holder,
such earlier time beginning after expiration of the "Market Standoff" set forth
in Section 1.13 at which all Registrable Securities held by such Holder (and any
affiliate of the Holder with whom such Holder must aggregate its sales under
Rule 144) can be sold in any three (3)-month period without registration in
compliance with Rule 144 of the Act.

     2.   Covenants of the Company.
          ------------------------

          2.1       Delivery of Financial Statements.  The Company shall deliver
                    --------------------------------
to each Investor holding shares of the Company:

                    (a) as soon as practicable, but in any event within ninety
(90) days after the end of each fiscal year of the Company, an income statement
for such fiscal year, a balance sheet of the Company and statement of
stockholder's equity as of the end of such year, and a statement of cash flows
for such year, such year-end financial reports to be in reasonable detail,
prepared in accordance with generally accepted accounting principles ("GAAP"),
and audited and certified by independent public accountants of nationally
recognized standing selected by the Company;

                    (b) as soon as practicable after the end of each quarter,
and in any event within forty-five (45) days after each quarterly accounting
period, an unaudited quarterly report including a balance sheet, income
statement and cash flow analysis (prepared in accordance with GAAP other than
for accompanying notes and subject to changes resulting from year-end audit
adjustments);

                    (c) as soon as practicable, but in any event at least thirty
(30) days prior to the end of each fiscal year, a budget and business plan for
the next fiscal year, prepared on a monthly basis, including balance sheets,
income statements and statements of cash flows for such months and, as soon as
prepared, any other budgets or revised budgets prepared by the Company; and

                    (d) such other information relating to the financial
condition, business, prospects or corporate affairs of the Company as the
Investor or any assignee of the Investor may from time to time request,
provided, however, that the Company shall not be obligated under this subsection
(d) or any other subsection of Section 2.1 to provide information that it deems
in good faith to be a trade secret or similar confidential information.

          2.2       Inspection.  The Company shall permit each Investor that
                    ----------
holds at least 2,478,600 shares of Registrable Securities, 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

                                     -12-
<PAGE>

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 that it reasonably considers to be a trade secret or similar
confidential information.

                    2.3 Termination of Information and Inspection Covenants.
                        ---------------------------------------------------
The covenants set forth in Sections 2.1 and 2.2 shall terminate as to Investors
and be of no further force or effect when the sale of securities pursuant to a
registration statement filed by the Company under the Act in connection with the
firm commitment underwritten offering of its securities to the general public is
consummated or when the Company first becomes subject to the periodic reporting
requirements of Sections 12(g) or 15(d) of the 1934 Act, whichever event shall
first occur.

                    2.4 Right of First Offer.  Subject to the terms and
                        --------------------
conditions specified in this paragraph 2.4 and in paragraph 2.12, the Company
hereby grants to each Major Investor (as hereinafter defined) a right of first
offer with respect to future sales by the Company of its Shares (as hereinafter
defined). For purposes of this Section 2.4, a Major Investor shall mean any
Investor or transferee that holds at least 1,239,300 shares of Registrable
Securities. For purposes of this Section 2.4, Investor includes any general
partners and affiliates of an Investor. An Investor shall be entitled to
apportion the right of first offer hereby granted it among itself and its
partners and affiliates in such proportions as it deems appropriate.

          Except as provided in subparagraph (d), each time the Company proposes
to offer any shares of, or securities convertible into or exchangeable or
exercisable for any shares of, any class of its capital stock ("Shares"), the
Company shall first make an offering of such Shares to each Major Investor in
accordance with the following provisions.

                        (a) The Company shall deliver a notice in accordance
with Section 4.5 ("Notice") to the Major Investors stating (i) its bona fide
intention to offer such Shares, (ii) the number of such Shares to be offered,
and (iii) the price and terms upon which it proposes to offer such Shares.

                        (b) By written notification received by the Company,
within twenty (20) calendar days after receipt of the Notice, the Major Investor
may elect to purchase or obtain, at the price and on the terms specified in the
Notice, up to that portion of such Shares that equals the proportion that the
number of shares of Registrable Securities then held by such Major Investor
bears to the total number of shares of Common Stock of the Company then
outstanding (assuming full conversion of all convertible securities). The
Company shall promptly, in writing, inform each Major Investor that elects to
purchase all the shares available to it (a "Fully-Exercising Investor") of any
other Major Investor's failure to do likewise. During the ten (10) day period
commencing after such information is given, each Fully-Exercising Investor may
elect to purchase that portion of the Shares for which Major Investors were
entitled to subscribe but which were not subscribed for by the Major Investors
that is equal to the proportion that the number of shares of Registrable
Securities then held by such Fully-Exercising Investor bears to the total number
of shares of Registrable Securities then held by all Fully-Exercising Investors
who wish to purchase some of the unsubscribed shares.

                                     -13-
<PAGE>

                    (c) If all Shares that Investors are entitled to obtain
pursuant to subsection 2.4(b) are not elected to be obtained as provided in
subsection 2.4(b) hereof, the Company may, during the ninety (90) day period
following the expiration of the period provided in subsection 2.4(b) hereof,
offer the remaining unsubscribed portion of such Shares to any person or persons
at a price not less than, and upon terms no more favorable to the offeree than,
those specified in the Notice. If the Company does not enter into an agreement
for the sale of the Shares within such period, or if such agreement is not
consummated within ninety (90) days of the execution thereof, the right provided
hereunder shall be deemed to be revived and such Shares shall not be offered
unless first reoffered to the Major Investors in accordance herewith.

                    (d) The right of first offer in this paragraph 2.4 shall not
be applicable to (i) the issuance or sale of shares of Common Stock (or options
therefor) granted after the date of this Amended and Restated Investors' Rights
Agreement, with the approval of a majority of the members of the Board of
Directors not holding management positions with the Company (and the reissuance
of any shares issued or subject to outstanding options returned to the Company
from any unexercised options or restricted stock repurchased by the Company
after such date), to employees, directors and consultants for the primary
purpose of soliciting or retaining their services pursuant to stock option plans
approved by the Board of Directors; (ii) the issuance of securities pursuant to
a bona fide, firmly underwritten public offering of shares of Common Stock,
registered under the Act, at an offering price of at least $2.88 per share
(appropriately adjusted for any stock split, dividend, combination or other
recapitalization) and resulting in proceeds to the Company of at least
$20,000,000 in the aggregate, (iii) the issuance of securities pursuant to the
conversion or exercise of convertible or exercisable securities, (iv) the
issuance of securities in connection with a bona fide business acquisition of or
by the Company approved by a majority of the Board of Directors of the Company,
whether by merger, consolidation, sale of assets, sale or exchange of stock or
otherwise, (v) the issuance of stock, warrants or other securities or rights,
with the approval of a majority of the Board of Directors of the Company, to
persons or entities with which the Company is entering or has entered into a
strategic relationship, (vi) the issuance of stock, warrants, or other
securities or rights in connection with and other bank debt financing,
commercial lending, equipment financings, capital lease, or similar
transactions, with the approval of a majority of the Board of Directors of the
Company, (vii) in the event that Intel Corporation and the Company agree on the
terms of a technology development relationship, the issuance of a warrant to
Intel Corporation to purchase up to 146,199 shares of Series C Preferred Stock
at $3.42 per share (subject to adjustment of such fixed dollar amounts for any
stock splits, stock dividends, combinations, recapitalizations or the like) and
the issuance of any Common Stock in connection with the conversion of such
preferred stock; (viii) the issuance of a warrant to Comdisco Inc. to purchase
6,397 shares of Series D Preferred Stock at $4.69 per share (subject to
adjustment of such fixed dollar amounts for any stock splits, stock dividends,
combinations, recapitalizations or the like) and the issuance of any Common
Stock in connection with the conversion of such preferred stock, or (ix) the
issuance of a warrant to Microsoft Corporation to purchase up to 218,120 shares
of Series D Preferred Stock at $5.96 (subject to adjustment of such fixed dollar
amounts for any stock splits, stock dividends, combinations, recapitalizations
or the like) and the issuance of any Common Stock in connection with the
conversion of such preferred stock.

               2.5  Termination of Right of First Offer.  The covenants set
                    -----------------------------------
forth in Section 2.4 shall terminate and be of no further force or effect upon
the consummation of, and shall not be applicable to, the sale of securities
pursuant to a bona fide, firmly underwritten public offering of shares of common
stock, registered under the Act, at an offering price of at least $2.88 per
share (appropriately adjusted for any stock split, dividend, combination or
other recapitalization) and resulting in proceeds to the Company of at least
$20,000,000.

               2.6  MTV Observer Rights.  As long as funds affiliated with Media
                    -------------------
Technology Ventures, L.P. ("MTV") in the aggregate own not less than fifty
percent (50%) of the shares of the Series B Preferred Stock such funds purchased
pursuant to that certain Series B Preferred Stock Purchase Agreement by and
among the Company and certain stockholders of the Company, dated as of June 8,
1998 (or an equivalent amount of Common Stock issued upon conversion thereof),
the Company shall invite a representative of MTV to attend all meetings of its
Board of Directors in a nonvoting observer capacity and, in this respect, shall
give such representative copies of all notices, minutes, consents, and other
materials that it provides to its directors; provided, however, that such
representative shall agree to hold in confidence and trust and to act in a
fiduciary manner with respect to all information so provided; and, provided
further, that the Company reserves the right to withhold any information and to
exclude such representative from any meeting or portion thereof if access to
such information or attendance at such meeting could adversely affect the
attorney-client privilege between the Company and its counsel or would result in

     Re:  Registration Statement on Form S-1


Ladies and Gentlemen:

     We have examined the Registration Statement on Form S-1, as amended, filed
by you with the Securities and Exchange Commission on February 1, 2000
(Registration No. 333-95833), as amended (the "Registration Statement"), in
connection with the registration under the Securities Act of 1933, as amended,
of up to 12,650,000 shares of your Common Stock, par value $0.0001 (the
"Shares").  The Shares include an over-allotment option granted to the
underwriters of the offering to purchase up to 1,650,000 shares.  We understand
that the Shares are to be sold to the underwriters of the offering for resale to
the public as described in the Registration Statement and pursuant to the
Underwriting Agreement filed as an exhibit thereto.  As your legal counsel, we
have examined the proceedings proposed to be taken in connection with said sale
and issuance of the Shares.

     It is our opinion that, upon completion of the proceedings being taken or
contemplated by us, as your counsel, to be taken prior to the issuance of the
Shares, including the proceedings being taken in order to permit such
transaction to be carried out in accordance with applicable state securities
laws, the Shares, when issued and sold in the manner described in the
Registration Statement, will be legally issued, fully paid and non-assessable.

     We are members of the Bar of the State of California only and express no
opinion as to any matter relating to the laws of any jurisdiction other than the
laws of the State of California and the federal laws of the United States.

     We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus constituting a part thereof,
and any amendment thereto.

                                        Very truly yours,

       to assist iBEAM with carrying out its obligations under this Agreement
       (with Microsoft selecting in its discretion which of these groups will
       provide support). Such support shall include providing reasonable on-site
       deployment support services to iBEAM, provided that Microsoft shall be
       entitled to charge iBEAM at its then-current rates for any such on-site

                   Microsoft Confidential & Proprietary                   Page 3
<PAGE>

       deployment support services which exceed a cumulative total of [*]
       person-weeks (i.e., a total of [*] hours).

2.3    Promotion of iBEAM's Services. In conjunction with its Broadband
       Streaming Initiative, Microsoft agrees to publicly announce that iBEAM is
       a Microsoft recommended solution provider for ICPs who are using WMT to
       run high bandwidth Streaming Media applications in a manner commercially
       similar to the level of promotion provided to the other application
       service providers who are Broadband Streaming Initiative Participants.
       Thereafter, during the Term, Microsoft will use commercially reasonable,
       good faith efforts to include and promote iBEAM as a provider of hosting
       and other applications and services related to Streaming Media, including
       without limitation as part of Microsoft's applicable marketing efforts
       and materials, sales training, Web sites, and other promotions,
       consistent with Microsoft's promotion of other Broadband Streaming
       Initiative application service providers which have entered into
       agreements with Microsoft on similar terms to this Agreement.

2.4    Early Releases. During the Term, Microsoft will provide to iBEAM, at no
       charge, successive pre-commercial releases (beta, and where practical as
       determined by Microsoft in its sole discretion, pre-beta) of Microsoft
       Software in object code form; provided, however, that nothing herein
       shall be deemed to require that Microsoft release any additional versions
       of the Microsoft Software during the Term. Any Microsoft Software
       provided hereunder may be used by iBEAM only in accordance with the
       confidentiality and license agreements accompanying such Microsoft
       Software and, in addition, may be used solely in connection with
       supporting the provision of iBEAM Services that use Windows Media
       Technologies. iBEAM understands that pre-release software is not intended
       for full scale commercial use.

2.5    Preconditions for Microsoft Sponsorship and Support Obligations. Each of
       Microsoft's obligations under this Section 2 is expressly conditioned
       upon iBEAM's performance of its obligations under Sections 3.1 through
       3.5 throughout the Term. In addition, because iBEAM has not fully
       formulated and shared with Microsoft its plans for the iBEAM Services as
       of the Effective Date, iBEAM agrees to confer in good faith with
       Microsoft promptly after the Effective Date in order to develop and set
       forth in writing, no later than ninety (90) days after the Effective
       Date, mutually approved performance objectives (the "Performance
       Criteria") for iBEAM's participation in the Broadband Streaming
       Initiative during the first two (2) years of the Term. If Microsoft
       reasonably believes that iBEAM has not met or exceeded such Performance
       Criteria during the first fifteen (15) months of the Term, then Microsoft
       may notify iBEAM of such determination by providing a written notice
       identifying the specific Performance Criteria which iBEAM has not met,
       provided that Microsoft must issue any such notice within ninety (90)
       days after the fifteen (15) month anniversary of the Effective Date. If,
       after receiving such a notice, iBEAM does not improve its performance
       such that it meets the Performance Criteria within sixty (60) days after
       receiving Microsoft's written notice hereunder, then Microsoft may in its
       discretion terminate this Agreement effective thirty (30) days after
       Microsoft provides written notice to iBEAM of such termination.

2.6    Digital Rights Management Application. To assist iBEAM in conducting an
       evaluation of Microsoft's Digital Rights Management applications ("DRM")
       in connection with iBEAM's services and applications related to Streaming
       Media, Microsoft agrees to provide iBEAM with reasonable access to
       applicable beta programs and other information on applicable new
       technologies and technical support offerings, subject to Microsoft's
       applicable confidentiality and license agreements.

2.7    Account Introductions. Microsoft agrees to use commercially reasonable
       efforts during the first ninety (90) days after the Effective Date to
       provide, on a non-exclusive basis, introductions to existing Microsoft
       account contacts in order to assist iBEAM's efforts to make initial
       presentations to selected Broadband Streaming Initiative ICP Participants
       and appropriate ISPs with respect to participation in the Broadband
       Streaming Initiative. The following is a preliminary list of anticipated
       accounts as to which Microsoft agrees, if and only to the extent it has
       appropriate existing contacts at such accounts as of the Effective Date,
       to use commercially reasonable efforts to introduce iBEAM to, in
       accordance with the foregoing sentence: [*].

2.8    International Marketing. Microsoft agrees to use commercially reasonable
       efforts to provide senior iBEAM managers with reasonable access (subject
       to availability) to Microsoft's applicable senior international managers
       in order to provide advice on entering international markets in
       connection with the Broadband Streaming Initiative. Microsoft agrees to
       make commercially reasonable efforts to help iBEAM identify and make
       initial executive level presentations to a mutually agreed list of tier
       one international accounts.

2.9    Reservation of Rights. Except as expressly licensed pursuant to this
       Agreement, iBEAM shall have no other rights in the Microsoft Software,
       the Windows Media Player or any other Microsoft software, technology or
       service provided to iBEAM hereunder. Microsoft retains all right, title
       and interest in and to the Microsoft Software, the Windows Media Player
       and any other Microsoft software, technologies and services. Nothing in
       this Agreement shall be construed, by implication, estoppel or otherwise,
       as granting iBEAM any rights to any Microsoft software, technology,
       service or other intellectual property rights.


3      iBEAM Obligations

3.1    Use and Promotion of Windows Media Technologies. Subject to Window Media
       Technologies being a competitively comparable solution to other Streaming
       Media technologies (as reasonably determined by iBEAM in good faith based
       on technology, price, quality and delivery timetables), throughout the
       Term, including without limitation as part of iBEAM's full services
       product launch, iBEAM will deploy, describe and promote Microsoft's WMT
       platform and formats to prospective and actual customers [*] iBEAM may
       also deploy, describe and promote other Streaming Media platforms or
       formats. iBEAM agrees to hold its full services platform launch within
       fifteen (15) days after Microsoft's initial public announcement of its
       Broadband Streaming Initiative.

       iBEAM's use and promotion of Windows Media Technologies shall further
       include, without limitation:

<PAGE>

   (a) Content Format. Within thirty (30) days after the Effective Date, and
       continuing thereafter throughout the Term, all Streaming Media available
       on the iBEAM Web Site shall be made available in Windows Media Format;
       provided, however, that nothing herein shall be deemed to prevent iBEAM
       from making Streaming Media available on such Web site in other formats.

   (b) Deployment of New Applications and Services. Throughout the Term, iBEAM
       will promote and make available to its customers all new applications and
       services related to Streaming Media on WMT platforms and in Windows Media
       Format concurrently with or sooner than iBEAM makes such new applications
       and services available based on or in conjunction with other Streaming
       Media technologies or formats, subject to the limitation that iBEAM's
       obligations hereunder with respect to release schedule parity are subject
       to Microsoft's providing comparable competitive offerings to other
       commercially available offerings in the area of Streaming Media
       technology or formats (as applicable) during the Term.

   (c) Sponsorship. Beginning on the Effective Date and continuing thereafter
       throughout the Term, iBEAM shall include on all pages of the iBEAM Web
       Site pages that relate to or contain Streaming Media or applications
       therefor a prominent "Get Windows Media Player" link logo (the "Windows
       Media Sponsorship Notice") which links to a Microsoft-authorized Windows
       Media Player download site, in accordance with the following terms:

       (i)     The Windows Media Sponsorship Notice shall appear prominently and
               Above the fold on each iBEAM Web Site page that contains or
               provides access to Streaming Media or that materially focuses on
               any iBEAM Service.

       (ii)    On all pages of the iBEAM Web Site, including without limitation
               those described in Section 3.1(c)(i), in the event iBEAM includes
               any information or notices concerning Streaming Media
               technologies or formats other than Windows Media Technologies and
               Windows Media Format, the Windows Media Sponsorship Notice shall
               appear on such page in a position at least as favorable in
               prominence, size and positioning as any other such notice.

       (iii)   In all cases, the Windows Media Sponsorship Notice shall be a
               minimum of 65 by 57 pixels (width by height), and shall conform
               to all trademark usage standards provided by Microsoft to iBEAM
               from time to time.

       (iv)    Microsoft shall be entitled to substitute a different hypertext
               link and/or link logo as the Windows Media Sponsorship Notice,
               subject to the same pixel size restrictions as are set forth in
               Section 3.1(c)(iii), in place of the "Get Windows Media Player"
               link logo for purposes of this Agreement, including without
               limitation iBEAM's responsibilities under this Section 3.1(c),
               upon Microsoft's reasonable advance written notice to iBEAM.

   (d) Additional Promotions. Microsoft and iBEAM will cooperate in good faith
       to identify and pursue additional opportunities for promotion of Windows
       Media Technologies in conjunction with the iBEAM Services to U.S.- based
       ICPs in the

                   Microsoft Confidential & Proprietary                   Page 6
<PAGE>

       [*].

   (e) Uses of the Get Windows Media Player Logo. All use by iBEAM of the "Get
       Windows Media Player" link logo (or any successor logo(s)) in connection
       with this Agreement is subject to compliance with Microsoft's guidelines
       relating to the use of such logo(s). The current version of such
       guidelines as of the Effective Date is set forth in Exhibit B hereto.

3.2  Provision of iBEAM Services to Broadband Streaming Initiative ICP
     Participants.

   (a) iBEAM agrees to provide six (6) months of iBEAM Services, to be comprised
       of broadband Streaming Media hosting, distribution and broadcasting
       services, at no charge (either to Microsoft or the ICP, and without
       applying Network Credits against the value of such services) to each
       Broadband Streaming Initiative ICP Participant that Microsoft designates
       in its discretion as a participant in the Broadband Streaming Initiative;
       provided, however, that such obligation shall not extend beyond the Term
       of this Agreement, and the value of such no-charge services in the
       aggregate for Broadband Streaming Initiative ICPs will not exceed Two
       Hundred Thousand Dollars ($200,000.00) as calculated using the rates
       described in Exhibit A. iBEAM will use commercially reasonable efforts to
       notify Microsoft in writing at least sixty (60) days before it
       anticipates exceeding the foregoing maximum value of the relevant iBEAM
       Services.

   (b) At Microsoft's request and at no charge to Microsoft or the applicable
       Internet Service Providers ("ISPs") and without applying Network Credits
       against the value of such services. iBEAM will install copies of the
       Microsoft Software and provide its standard level of customer service for
       such software during the Term in order to support ISPs which Microsoft
       has designated in its discretion to participate in the Broadband
       Streaming Initiative. In performing the foregoing obligations, iBeam
       shall maintain and comply with separate written agreements with Microsoft
       and/or its licensees with respect to installation and support of the
       Microsoft Software, and nothing in this Agreement shall be deemed to
       authorize iBeam to install and/or support such copies of the Microsoft
       Software.

   (c) In addition to the obligations of iBEAM under Sections 3.2(a) and (b),
       Microsoft shall be entitled to apply its prepaid Network Credits and
       thereby obtain iBEAM Services for the benefit of designated ICP
       Participants in accordance with this Agreement (including without
       limitation Exhibit A). In the event that Microsoft authorizes iBEAM to
       provide iBEAM Services that exceed in value (as calculated pursuant to
       the terms set forth in Exhibit A) the value of then-existing pre-paid
       balance of Network Credits, Microsoft agrees to pay iBEAM for such iBEAM
       Services in accordance with iBEAM's then-current pricing to third parties
       which are purchasing iBEAM Services in aggregate volumes comparable to
       those being purchased by Microsoft in connection with the use of Network
       Credits under this Agreement.

3.3  Promotion of Internet Radio Networks.  iBEAM agrees to provide highly
     ------------------------------------
     competitive fixed rate pricing for iBEAM Services to radio networks or
     stations that iBEAM and Microsoft in

[*] Certain information on this page has been omitted and filed separately with
the Commission. Confidential treatment has been requested with respect to the
omitted portions.

                   Microsoft Confidential & Proprietary                   Page 7
<PAGE>

     their reasonable discretion mutually designate to participate in such
     manner in the Broadband Streaming Initiative. [*] iBEAM shall provide such
     fixed rate pricing [*] that each designated radio network or station
     participates in this program, provided that such customers enter agreements
     with terms equal to or greater than [*] and agree to make commercially
     reasonable efforts to promote their use of iBEAM's services.

3.4  Publicity. iBEAM will work with Microsoft to develop a mutually agreeable
     ---------
     press release to be released as soon as possible after the Effective Date,
     provided that the text of such release must have been approved in writing
     by each party before its release. In such release, iBEAM shall endorse
     Windows Media Technologies, and Windows Media Format as being recommended
     by iBEAM as its recommended platform and formats for its services and
     applications. Further, subject to the limitations set forth in the next
     sentence hereof, iBEAM agrees that (a) it will not release or approve any
     press releases using its name or descriptions of the iBEAM Services, other
     than in conjunction with promotions of Windows Media Technologies as
     described above, for [*] before the initial announcement contemplated by
     the previous sentence, nor for [*] following such initial announcement, and
     (b) at all times during the Term, iBEAM shall not issue or approve press
     releases from third parties that are inconsistent with the spirit of this
     Section 3.4. Notwithstanding the restrictions set forth in the previous
     sentence, iBEAM shall be entitled to perform under any contractual
     obligation existing as of the Effective Date which requires iBEAM to
     release or approve press releases or making other announcements during the
     Term; provided, however, that to the extent iBEAM can comply with such
     contractual obligations and also comply with the time limitations set forth
     in the previous sentence, it shall do so. During the Term, iBEAM will also
     work with Microsoft to develop and release joint press announcements,
     provided that the details of each such announcement must have been approved
     in writing by each party before it occurs, and iBEAM agrees to provide
     Microsoft with reasonably detailed information on iBEAM's use of Microsoft
     technology in its iBEAM Web Site for inclusion in a case study which iBEAM
     shall be entitled to review and approve. With respect to all approvals
     contemplated by this Section 3.4, the parties agree not to unreasonably
     withhold or delay such approvals.

3.5  Reporting and Audits.  By the tenth (10/th/) day of each calendar month
     --------------------
     during the Term (other than the month in which the Effective Date falls),
     iBEAM shall provide a report to Microsoft setting forth the following
     information concerning the previous calendar month, to the extent iBEAM's
     provision of such information to Microsoft does not conflict with any
     obligation of iBEAM to a customer and is reasonably available from iBEAM's
     reporting systems (and provided further that if iBEAM's reporting systems
     do not enable it to provide any element of such reports, iBEAM will
     promptly confer in good faith with Microsoft to pursue possible ways to
     enable such reporting systems to provide the requested information):

     (a)  The URL and number of page views for pages on the iBEAM Web Site or
          third party web sites hosted by iBEAM which contain Streaming Media;
     (b)  The number of referrals of end users from the iBEAM Web Site or third
          party web sites hosted by iBEAM to Microsoft's Windows Media Player
          download site(s);
     (c)  Web browsing software share and Streaming Media player share
          information for the iBEAM Web Site and third party web sites hosted by
          iBEAM; include version information;

[*]  Certain information on this page has been omitted and filed separately with
the Commission. Confidential treatment has been requested with respect to the
omitted portions.

                   Microsoft Confidential & Proprietary                   Page 8
<PAGE>

     (d)  The number of streams served, including the total number of .wma, .asx
          and .asf format files served, by bit rate;
     (e)  The average length of a user stream for a single connection to the
          iBEAM Web Site and third party web sites hosted by iBEAM;
     (f)  The number of streams of pages with feature/streaming technology; and
     (g)  The average number of .wma, .wmx, and .asx files on site.

     iBEAM shall provide all reports hereunder to Microsoft via Microsoft's web
     reporting system located at [*], or any successor thereto.

     In the event that iBEAM has failed to provide a report as described in this
     Section 3.5 on or before the tenth (10/th/) day of the relevant calendar
     month, then Microsoft will be entitled to suspend its performance under
     this Agreement (including without limitation its payment obligations under
     Section 2.1) until such report has been received. All information provided
     pursuant to this Section will be deemed to be Confidential Information of
     iBEAM.

3.6  Additional Trademark Use.  iBEAM further agrees to use all Windows Media
     ------------------------
     Technologies-related logos in accordance with the applicable logo program
     requirements established by Microsoft in its sole discretion from time to
     time. In the event that iBEAM fails to comply with Microsoft's then-current
     logo requirements for participation in the Streaming Media Initiative at
     any time during the Term, then Microsoft will be entitled, after providing
     iBEAM with notice of breach and an opportunity to cure such breach within
     thirty (30) days, to suspend its performance under this Agreement and
     terminate this Agreement (including without limitation Microsoft's payment
     obligations under Section 2.1) upon further written notice to iBEAM.

3.7  Technology Development and Testing Discussions.  iBEAM agrees that upon
     ----------------------------------------------
     request and subject to the parties' prior mutual written agreement with
     respect to applicable intellectual property ownership and licenses, iBEAM
     will make its appropriate senior technical personnel available to discuss
     architecture and beta release testing matters with Microsoft in relation to
     the following areas of mutual interest concerning technology development:
     [*]. Microsoft agrees to provide pre-commercial releases of Microsoft
     Software as specified under Section 2.4.

3.8  Digital Rights Management Applications.  iBEAM intends to implement and
     --------------------------------------
     license Microsoft Digital Rights Management "DRM" technologies and services
     in connection with the iBEAM Services, provided, however, that Microsoft
     technologies and services can be rejected by iBEAM if it evaluates and in
     good faith reasonably deems them not to be commercially competitive with
     respect to alternatives in the areas of technology, price, quality, and
     delivery timetables, taken as a whole. In the event that any such
     technology or service is reasonably deemed not to be competitive, iBEAM
     agrees to provide Microsoft a written notice describing in reasonable
     detail the reason(s) why the Microsoft offering has been deemed not to be
     competitive and the opportunity to discuss and address such shortfalls.
     Upon iBEAM's final selection (if any) of Microsoft's DRM technologies and
     services, the parties further agree to negotiate in good faith for a
     commercially reasonable period concerning the applicable license and
     support terms and concerning joint promotional efforts the parties may
     engage in with respect to iBEAM's implementation of

[*] Certain information on this page has been omitted and filed separately with

<PAGE>

    DRM, and upon entering into any such agreement iBEAM agrees that it will
    deploy, describe and promote Microsoft's DRM technologies and services to
    prospective and actual customers as its recommended digital rights
    management solutions for iBEAM services; provided, however, that iBEAM may
    also deploy, describe and promote other digital rights management solutions.


4.  Additional Understandings

4.1 Corporate Solutions.  Subject to Window Media Technologies being a
    -------------------
    competitively comparable solution to other Streaming Media technologies (as
    reasonably determined by iBEAM in good faith based on technology, price,
    quality and delivery timetables) iBEAM agrees to promote Microsoft Software
    and Windows Media Technologies as its recommended platform and solutions
    with respect to all Streaming Media-related services and solutions that
    iBEAM may offer to corporate customers (e.g., to support intranets) during
    the Term. iBEAM agrees to make good faith efforts to share its product and
    sales plans for such marketplace with Microsoft promptly upon their
    development. Microsoft acknowledges that all such prospective plans shall be
    deemed to be Confidential Information of iBEAM.

4.2 International Service Rollout.  iBEAM agrees to use commercially reasonable
    -----------------------------
    efforts to provide Microsoft [*], subject to the provisions of this Section
    4.2, to [*] on then-standard commercial terms to support iBEAM's rollout of
    its network and services internationally as part of joint ventures and other
    affiliations in which iBEAM does not independently control technology
    deployment. In all applicable iBEAM international efforts, iBEAM will
    endeavor in good faith to provide Microsoft a [*] in order to implement and
    license Microsoft technologies and services as referenced herein, provided,
    however, that [*]. iBEAM and its international affiliates may make the final
    selection based on its sole discretion in accordance with this paragraph.

4.3 Other Opportunities.  iBEAM agrees to notify and offer Microsoft [*], on the
    -------------------
    same basis as described in Section 4.2, with respect to any and all
    Streaming Media-related initiatives, applications, services and other
    offerings that iBEAM may develop or offer during the Term of this Agreement.

5.   Non-Exclusive

Nothing in this Agreement shall be deemed to restrict either party's ability to
license, develop, sub-license, manufacture, deploy, support, promote, or
distribute software, Content, Streaming Media or any other format or technology,
whether or not similar to Windows Media Technologies or any iBEAM Services.


6.   Confidentiality

6.1  Each party shall protect the other's Confidential Information from
     unauthorized dissemination and use with the same degree of care that such
     party uses to protect its own like information and in no event using less
     than a reasonable degree of care. Neither party will use the other's
     Confidential Information for purposes other than those necessary to
     directly further the purposes of this Agreement. Neither party will
     disclose to third parties the other's Confidential Information without the
     prior written consent of the other party. Except as expressly provided in
     this Agreement, no ownership or license rights are granted in any
     Confidential Information. The other provisions of this Agreement
     notwithstanding, either party will be permitted to disclose the
     Confidential Information to their outside legal and financial advisors; and
     to the extent required by applicable law, provided however that before
     making any such required filing or disclosure, the disclosing party shall
     first give written notice of the intended disclosure to the other party,
     within a reasonable time from the time disclosure is requested and in any
     event prior to the time when disclosure is to be made, and the disclosing
     party will exercise best efforts, in cooperation with and at the expense of
     the other party, consistent with reasonable time constraints, to obtain
     confidential treatment for all non-public and sensitive provisions of this
     Agreement, including without limitation dollar amounts and other numerical
     information.

6.2  The parties' obligations of confidentiality under this Agreement shall not
     be construed to limit either party's right to independently develop or
     acquire products without use of the other party's Confidential Information.
     Further, either party shall be free to use for any purpose the residuals
     resulting from access to or work with such Confidential Information,
     provided that such party shall maintain the confidentiality of the
     Confidential Information as provided herein. The term "residuals" means
     information in non-tangible form, which may be retained by persons who have
     had rightful and good faith access to the Confidential Information,
     including ideas, concepts, know-how or techniques contained therein.
     Neither party shall have any obligation to limit or restrict the assignment
     of such persons or to pay royalties for any work resulting from the use of
     residuals. However, the foregoing shall not be deemed to grant to either
     party a license under the other party's copyrights or patents.


7.   Warranties and Disclaimers

7.1  Warranties.  Each party warrants and covenants that it has the full power
     ----------
     and authority to enter into and perform according to the terms of this
     Agreement.

7.2  DISCLAIMERS.  ANY AND ALL SOFTWARE, TECHNOLOGY, SERVICES, CONTENT, OR
     -----------
     INFORMATION PROVIDED BY EITHER PARTY TO THE OTHER

              Microsoft Confidential & Proprietary                       Page 11

     HEREUNDER IS PROVIDED "AS IS," WITHOUT WARRANTY OF ANY KIND. EACH PARTY
     DISCLAIMS ALL WARRANTIES, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT
     LIMITED TO THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A
     PARTICULAR PURPOSE, TITLE AND NONINFRINGEMENT, WITH RESPECT TO ANY
     SOFTWARE, TECHNOLOGY, SERVICES, CONTENT, OR INFORMATION PROVIDED HEREUNDER.


8.   Indemnity

8.1  Indemnity.  iBEAM shall, at its expense and Microsoft's request, defend
     ---------
     any claim or action brought by a third party against Microsoft, or
     Microsoft's affiliates, directors, or officers, to the extent it is based
     upon a claim involving the iBEAM Services and/or the iBEAM Web Site,
     including without limitation any claim that any iBEAM Services or any
     Content included in or uploaded to the iBEAM Web Site infringes or violates
     any copyright, patent, trademark, trade secret, right of publicity, or
     other intellectual property, proprietary or contractual right of a third
     party (all such claims or actions being referred to hereinafter as "iBEAM
     Claims"), and iBEAM will indemnify and hold Microsoft harmless from and
     against any costs, damages and fees reasonably incurred by Microsoft,
     including but not limited to fees of outside attorneys and other
     professionals, that are attributable to such iBEAM Claims. Microsoft shall:
     (a) provide iBEAM reasonably prompt notice in writing of any such iBEAM
     Claims and permit iBEAM, through counsel chosen by iBEAM, to answer and
     defend such iBEAM Claims; and (b) provide the entity defending such claim
     information, assistance and authority, at such entity's expense, to help
     defend such iBEAM Claims. iBEAM will not be responsible for any settlement
     made by Microsoft without iBEAM's written permission, which permission will
     not be unreasonably withheld or delayed. Reasonable withholding of
     permission may be based upon, among other factors, editorial and business
     concerns. iBEAM will consult with Microsoft on the choice of any counsel
     under this Section 8.1. In the event Microsoft receives any iBEAM Claim or
     Microsoft has reason to believe it may be subject to any iBEAM Claim,
     Microsoft shall be entitled, upon written notice to iBEAM, to suspend
     performance under this Agreement (other than Microsoft's obligations under
     Section 2.1) with respect to the applicable iBEAM Services, iBEAM Web Site
     or Content thereon until iBEAM has taken steps to Microsoft's satisfaction
     in order to address the alleged infringement. If iBEAM does not take
     satisfactory steps to address the alleged infringement within fifteen (15)
     days after receiving a notice from Microsoft under the foregoing sentence,
     then Microsoft in its discretion may terminate this Agreement upon written
     notice to iBEAM and such termination shall be deemed to be a termination
     for cause for purposes of Section 9.

8.2  Settlement by iBEAM.  Unless iBEAM obtains for Microsoft a complete release
     -------------------
     of all iBEAM Claims thereunder, iBEAM may not settle any iBEAM Claim under
     this Section 8 on Microsoft's behalf without first obtaining Microsoft's
     written permission, which permission will not be unreasonably withheld or
     delayed. Reasonable withholding of permission may be based upon, among
     other factors, the ability for Microsoft to ship any product. In the event
     iBEAM and Microsoft agree to settle an iBEAM Claim, iBEAM agrees not to
     disclose terms of the settlement without first obtaining Microsoft's
     written permission, which will not be unreasonably withheld or delayed.

9.   Termination

9.1  Termination By Either Party.  Either party may suspend performance and/or
     ---------------------------
     terminate this Agreement as expressly provided elsewhere in this Agreement
     or:

     (a) Immediately upon written notice at any time, if the other party is in
         material breach of any material warranty, term, condition or covenant
         of this Agreement, other than those contained in Section 6, and fails
         to cure that breach within [*] after written notice thereof; or

     (b) Immediately upon written notice at any time, if the other party is in
         material breach of Section 6.

9.2  Effect of Termination.
     ---------------------

     (a) Neither party shall be liable to the other for damages of any sort
         resulting solely from terminating this Agreement in accordance with its
         terms.

     (b) Termination of this Agreement shall not affect any other agreement
         between the parties.

     (c) Should either iBEAM or Microsoft terminate for cause pursuant to
         Section 8.1, 9.1(a), or 9.1(b), neither party shall have any further
         obligations to the other under Sections 2.1-2.9, Section 3.1-3.8, or
         Section 4.1-4.3, with the exception that Microsoft shall be entitled in
         its discretion either (i) to use, within [*] of such termination, any
         Network Credits representing amounts previously paid by Microsoft
         under this Agreement which have not been recouped via use of Network
         Credits as of the termination of this Agreement; or (ii) to require
         iBEAM to refund the portion of the Network Credit Fee Amount then
         having been paid by Microsoft and not (as of the termination date)
         used to provide iBEAM Services for the parties and purposes specified
         in Section 2.1 and Exhibit A, provided that in no event shall iBEAM
         be obligated to refund more than [*] of the total Network Credit Fee
         Amount paid to iBEAM by Microsoft during the twelve (12) months prior
         to Termination. Without limiting the generality of the foregoing,
         Microsoft will have no obligation following termination of this
         Agreement to make any additional payments or provide any further
         services to iBEAM under Section 2 of this Agreement.

9.3  Survival.  In the event of termination or expiration of this Agreement for
     --------
     any reason, Sections 1, 2.9, and 5-11 shall survive termination and
     continue in effect in accordance with their terms.

     or to such other address as a party may designate pursuant to this notice
     provision.

11.2 Independent Parties. Nothing in this Agreement shall be construed as
     -------------------
     creating an employer-employee relationship, an agency relationship, a
     partnership, or a joint venture between the parties.

11.3 Governing Law.  This Agreement will be governed by the laws of the State of
     -------------
     Washington, without reference to the conflict of law principles thereof.
     Any action or litigation concerning this Agreement will take place
     exclusively in the federal or state courts in King County, Washington, and
     the parties expressly consent to jurisdiction of and venue in such courts
     and waive all defenses of lack of personal jurisdiction and forum non
     conveniens

              Microsoft Confidential & Proprietary                       Page 14
<PAGE>

     with respect to such courts. iBEAM hereby agrees to service of process by
     mail or other method acceptable under the laws of the State of Washington.

11.4 Attorneys' Fees.  In any action or suit to enforce any right or remedy
     ---------------
     under this Agreement or to interpret any provision of this Agreement, the
     prevailing party shall be entitled to recover its costs, including
     reasonable attorneys' fees.

11.5 Assignment.  This Agreement and any rights or obligations hereunder may not
     ----------
     be assigned by iBEAM (including without limitation via merger, stock
     purchase, a sale of substantially all assets, or otherwise by operation of
     law) without Microsoft's prior written approval which shall not be
     unreasonably withheld or delayed. Notwithstanding the foregoing, iBEAM may
     assign this Agreement in its entirety as part of a change in control of
     iBEAM, provided that the assignee is not a software platform provider
     (e.g., and without limitation, [*]) and does not develop and license
     Streaming Media technologies or platforms (e.g., and without limitation
     [*]); the parties further agree that it shall be deemed reasonable for
     Microsoft to elect in its discretion not to approve a proposed assignment
     to a software platform provider or a developer/licensor of Streaming Media
     technologies or platforms. Any attempted assignment, sub-license, transfer,
     encumbrance or other disposal by iBEAM which requires Microsoft's approval
     and which has not been so approved will be void and will constitute a
     material default and breach of this Agreement for which Microsoft may
     terminate this Agreement in accordance with Section 9.1. Except as
     otherwise provided, this Agreement will be binding upon and inure to the
     benefit of the parties' successors and lawful assigns.

11.6 Force Majeure.  Neither party shall be liable to the other under this
     -------------
     Agreement for any delay or failure to perform its obligations under this
     Agreement if such delay or failure arises from any cause(s) beyond such
     party's reasonable control, including by way of example labor disputes,
     strikes, acts of God, floods, fire, lightning, utility or communications
     failures, earthquakes, vandalism, war, acts of terrorism, riots,
     insurrections, embargoes, or laws, regulations or orders of any
     governmental entity.

11.7 Construction.  If for any reason a court of competent jurisdiction finds
     ------------
     any provision of this Agreement, or portion thereof, to be unenforceable,
     that provision of the Agreement will be enforced to the maximum extent
     permissible so as to effect the intent of the parties, and the remainder of
     this Agreement will continue in full force and effect. Failure by either
     party to enforce any provision of this Agreement will not be deemed a
     waiver of future enforcement of that or any other provision. This Agreement
     has been negotiated by the parties and their respective counsel and will be
     interpreted fairly in accordance with its terms and without any strict
     construction in favor of or against either party.

11.8 Entire Agreement.  This Agreement does not constitute an offer by Microsoft
     ----------------
     and it shall not be effective until signed by both parties. This Agreement
     constitutes the entire agreement between the parties with respect to the
     subject matter hereof and merges all prior and contemporaneous
     communications. It shall not be modified except by a written agreement
     dated subsequent to the date of this Agreement and signed on behalf of
     iBEAM and Microsoft by their respective duly authorized representatives.

IN WITNESS WHEREOF, the parties have entered into this Agreement as of the
Effective Date written above.

1.   Approval of Program Participants
     --------------------------------

     Microsoft shall have sole discretion regarding the designation of Broadband
Streaming Initiative ICP Participants and allocation of Network Credits for use
by such entities and/or Microsoft's internal use under this Agreement.
Microsoft shall make reasonable efforts to provide Network Credits to customers
and programs that iBEAM recommends for the Broadband Streaming Initiative.  In
no event shall iBEAM provide any Microsoft Confidential Information to any
customer or prospective customer except with Microsoft's express written
approval. Microsoft shall notify iBEAM from time to time in writing of approved
Broadband Streaming Initiative ICP Participants, the particular iBEAM Services
to be used by each such entity pursuant to this Agreement, and the approved
allocation of Network Credits among such entities and Microsoft (if applicable).
Microsoft and iBEAM will cooperate in good faith following the Effective Date to
develop and implement operational procedures, including prior approvals for
sales programs, to coordinate the use of Network Credits in accordance with this
Agreement.

2.   Terms of Service
     ----------------

     Notwithstanding anything to the contrary in the foregoing paragraph, the
relationship between iBEAM and any Broadband Streaming Initiative ICP
Participant shall be separate from iBEAM's relationship with Microsoft and iBEAM
shall have the right to choose, in its sole discretion, not to do business with
any Broadband Streaming Initiative ICP Participant.  iBEAM shall enter into a
separate agreement, in a timely manner, with each Broadband Streaming Initiative
ICP Participant to which iBEAM intends to provide iBEAM Services pursuant to
this Agreement, and iBEAM shall perform all such iBEAM Services in a manner as
mutually agreed upon by iBEAM and each such Broadband Streaming Initiative ICP
Participant.  iBEAM shall be solely responsible for all services it provides to
Broadband Streaming Initiative ICP Participants, including without limitation
the iBEAM Services, and for enforcing the terms of any services or other
agreements it enters into with Broadband Streaming Initiative ICP Participants.

     At Microsoft's sole discretion, iBEAM may perform iBEAM Services for
Microsoft acting on behalf of a Broadband Streaming Initiative ICP Participant,
in which event such provision of iBEAM Services shall be subject to the terms of
this Agreement and any further services agreement that Microsoft and iBEAM may
mutually agree upon.

3.   Rate Schedule
     -------------

     [*]  Net Credits consumed by iBEAM customers shall be in accordance with
terms mutually approved by Microsoft and iBEAM and included in the operational
procedures specified in paragraph 1 above.

[LOGO OF WILLIAMS]



                          Teleport Services Agreement

This is an agreement between Williams Vyvx Services, a business unit of Williams
Communications, Inc., ("Williams") and iBEAM Broadcasting Corporation
("Customer"), dated as of December 13, 1999, in connection with teleport
services to be provided by Williams from Williams Vyvx Teleport New York as its
primary signal path and Williams Vyvx Teleport Los Angeles as its redundant
signal path  (the "Teleport(s)") to Customer (the "Agreement").  The terms of
this Agreement are as follows:

1.   SERVICES. Williams shall provide Customer with the Teleport services as
     --------
     further described on Exhibit A-1 attached hereto and made a part hereof
     (collectively referred to herein as the "Services"). From time to time and
     subject to availability, changes may be made in the Services which will be
     reflected in amendments to the applicable Exhibit A or the addition of
     additional Exhibit As. Each amendment shall be executed by authorized
     individuals of both parties. Each Exhibit A shall be part of this Agreement
     and incorporated herein. All Exhibit As shall be sequentially numbered for
     ease of identification, e.g., Exhibits A-1, A-2, A-3 and so forth.

2.   TERM. Upon signature by both parties this Agreement shall become effective
     ----
     on the date first set forth above and shall continue in effect until the
     expiration of any Exhibit A attached hereto (the "Term").

3.   LATE PAYMENT.  If any payment is not received by Williams within 30 days
     ------------
     after the date of invoice (the "Due Date"), then such overdue amount shall
     be subject to late payment charges at the lower of 18% per annum or the
     highest legally permissible rate of interest until the date payment is
     actually received. If Customer in good faith disputes any portion of an
     invoice it must pay the undisputed amount of the invoice on or before its
     Due Date and provide written notice to Seller of the billing dispute at or
     before the time of payment. Such notice must include documentation
     substantiating the dispute. Customer's failure to notify Seller of a
     dispute within one hundred-twenty (120) days after the Due Date shall be
     deemed to be Customer's acceptance of such charges. The parties will make a
     good faith effort to resolve billing disputes as expeditiously as possible.
     If a dispute is resolved in favor of Customer, Customer shall receive an
     adjustment on its next bill.

4.   SUSPENSION RIGHT.  In the event that Customer has failed to pay any
     ----------------
     undisputed amount when due, Williams shall have the right to suspend
     Services. Williams shall only exercise this Suspension Right by first
     providing Customer with ten business days' written notice by facsimile. If
     Williams receives payment from Customer of all amounts due within the ten-
     day notice period, then Customer's Services shall not be suspended.
     Suspension of Services does not affect Customer's obligation to pay the
     Service Charges through the Term of this Agreement unless Customer
     exercises its termination right as described in this Section 4. In the
     event Williams suspends Customer's Services, Customer shall have the right
     but not the obligation to terminate this Agreement at its sole discretion.
     Customer's liability with respect to such termination shall be an amount
     equal to twelve (12) months of Service from the date of termination
     multiplied by the then current monthly Total Service Charge or an amount
     equal to the number of months remaining in the Term multiplied by the then
     current monthly Total Service Charge, whichever is less.

                                                                   Page 1 of 26
<PAGE>

5. TERMINATION.
   -----------

5.1  Customer shall have the right to terminate this Agreement upon a minimum of
     thirty (30) days' written notice. This right to terminate may only be
     exercised due to one of the following two circumstances:

     a.  Monthly Interruptions exceed 43 minutes in three (3) consecutive
         calendar months; or

     b.  A second Daily Interruption in excess of 24 consecutive hours (after
         the first Daily Interruption in excess of 24 consecutive hours).

     Customer must exercise its right to terminate pursuant to this Section 5.1
     within thirty (30) days of the circumstance giving rise to Customer's right
     to terminate. This right to terminate is Customer's only right to terminate
     due to excessive Interruptions, and Customer may not invoke the general
     termination right as set forth in Section 5.2 due to Interruptions.

5.2  Either party may terminate this Agreement due to a material breach of this
Agreement by the other party. The non-breaching party shall provide written
notice to the breaching party of the alleged breach, and the breaching party
shall have sixty (60) days to cure the breach. If the breach has not been cured
within this sixty-day period, then the non-breaching party may terminate upon
thirty (30) days' written notice. Customer shall pay Williams in accordance with
this Agreement for all Services performed up to and including the effective date
of termination.

6. TAXES.  Customer acknowledges and understands that all charges are computed
   -----
   exclusive of any applicable federal, state or local use, excise, gross
   receipts, sales and privilege taxes, duties, fees or similar liabilities
   (other than general income or property taxes), including without limitation,
   any tax or charge levied to support the Universal Service Fund contemplated
   by the Telecommunications Act of 1996, whether charged to or against
   Williams, its suppliers or affiliates or Customer for the Service provided to
   Customer ("Taxes"). Such Taxes shall be paid by Customer in addition to all
   other charges provided for herein.

7. OUTAGE ALLOWANCE.
   ----------------

7.1  Calculation of Outage Allowance.  If applicable, Williams shall grant
     -------------------------------
        Customer an Outage Allowance for Services as follows:

        (a)  For purposes of this Agreement an interruption to Services
             ("Interruption") will be deemed to have occurred when Services are
             either not provided at all or fail to meet the requirements of the
             Agreement for a period of ten aggregate minutes on any given
             calendar day (the "Daily Interruption") or forty-three (43)
             aggregate minutes in any given calendar month (the "Monthly
             Interruption"). An Interruption begins the earlier of when Customer
             notifies Williams of the Interruption or when Williams is actually
             aware of the Interruption or constructively aware through
             recordation of the Interruption in Williams' log files. An
             Interruption will be considered to have ended when Services in
             accordance with this Agreement have been restored.

       (b)   In the event that Williams has a Daily Interruption as set forth in
             Section 7.1(a) herein, Customer shall receive a credit for the day
             the Daily Interruption occurred. Such credit shall include all fees
             for the day containing the Daily Interruption related to the
             Primary uplink (the "Uplink Outage Allowance"), which represents
             62.5% of the total daily uplink fee.

       (c)   In addition to the Uplink Outage Allowance, a credit will be
             provided to Customer by Williams based on the outage formula below
             for the actual outage minutes related to the Space Segment (the
             "Space Segment Outage Allowance").

                                                                    Page 2 of 26
<PAGE>

                                   43,200 (deemed number of minutes per month)

     (d)  In the event Williams has a Monthly Interruption as set forth in
          Section 7.1(a) herein, Customer shall receive a credit for the month
          in which the Monthly Interruption took place. Such credit will include
          an Uplink Outage Allowance as defined herein for the month containing
          the Monthly Interruption. If Customer receives a credit for a Monthly
          Interruption, Customer shall not receive credits for any Daily
          Interruptions which occurred during the month in which the Monthly
          Interruption occurred.

  7.2  Audio/Video. Intentionally Left Blank.
       ------------

  7.3  Exceptions to Outage Allowance.  In no case shall an Outage Allowance be
       -------------------------------
       made for any Interruption that is a result of, or attributable in whole
       or in part to:

       (a)  Any failure on the part of Customer to perform its material or
            operational obligations pursuant to this Agreement;

       (b)  The failure of Customer's Signal provided by Customer or by carriers
            other than Williams;

       (c)  The failure of transmission lines, equipment, or other facilities
            provided by the Customer;

       (d)  The failure or nonperformance of any earth station not provided by
            Williams;

       (e)  Reasonable periodic maintenance as approved in advance by Customer,
            provided Williams provides Customer with 72 hours advance notice of
            such maintenance and cumulative maintenance time does not exceed two
            (2) hours per calendar month;

       (f)  Interference from third party transmission or usage;

       (g)  Cooperative testing;

       (h)  Sun transit outage or rain fade; or

       (i)  Any other act or failure to act by Customer.



  7.4  Credit Memoranda.  Interruptions and Outage Allowances shall be
       -----------------
       acknowledged by Williams through the issuance of credit memoranda.  Such
       memoranda shall be issued within fifteen (15) days of the close of each
       calendar month and shall reflect all credit allowances accumulated by
       Customer during such month.  Customer may deduct from its next monthly
       payment the amount specified in the credit memorandum received in the
       preceding month.

  7.5  Time Limitation.  In no event shall Williams be liable for allowances for
       ---------------
       interruption unless the claim for such allowance is made within fifteen
       (15) days after the date of the interruption.

8.  WILLIAMS' RIGHT TO RE-CONFIGURE TELEPORT.  Williams shall have the right to
    ----------------------------------------
    re-configure or relocate the Teleport. Notwithstanding the above, any re-
    configuration must have minimal impact on any Customer performance
    requirement, and any relocation will be within the continental United States
    and will require that the two Teleports used by Customer must be at a
    minimum 1000 miles apart and neither shall be located in Florida or southern
    Texas.

                                                                    Page 3 of 26

       and 9.1(c), Customer agrees to waive and will require its insurers to
       waive any rights of subrogation or recovery they may have against

       recovery they may have against Williams, its parent, subsidiary, or
       affiliated companies under 9.1(b).

       respects Williams.

  9.4  Certificates of Insurance. Non-renewal or cancellation of policies
       -------------------------
       described above will be effective only after written notice is received
       by Williams from the insurance company thirty (30) days in advance of any

       Service hereunder, Customer will deliver to Williams certificates of
       insurance on an ACORD 25 or 25S form evidencing the existence of the
       insurance coverages required above. In the event of a loss or claim
       arising out of or in connection with the work performed under this

       original or a certified copy of its insurance policies for inspection by
       Williams.

5.2  Space Segment  (the "Transponders")

a)  Williams shall provide two Ku-band transponders (the "Transponders") on
    Telstar 7 at the 129 West orbital slot. The Transponders shall be provided
    on a "ramp-up" schedule by which Customer commits to pay for increasing
    amounts of the space segment on the Transponders. The ramp-up schedule is
    depicted on the Ramp-Up and Pricing Schedule attached hereto as Exhibit D.
    Customer's commitment for the space segment depicted on Exhibit D begins on
    the first day of the first month of the respective quarter identified. With
    appropriate notice, Customer may accelerate the ramp-up of space segment,
    together with the corresponding charges. Once an increased level of space
    segment has been activated, however, the level may not be decreased. The
    full use of both Transponders as depicted on Exhibit D beginning no later
    than [*] shall continue through the end of the Term of the Agreement. The
    second transponder is subject to the Right of First Refusal described below
    in subparagraph (c).

b)  Additional bandwidth is available under the Bursting provision in Section
    6.6 (b) herein.

c)  Williams shall provide Customer with a Right of First Refusal on a Fully-
    Protected Ku-band transponder on Telstar 7. The Right of First Refusal shall
    be activated at the time Loral Skynet receives a bona fide offer for Loral's
    last Fully Protected Ku-band transponder on Telstar 7. In order to implement
    such Right-of-First Refusal, Williams shall provide Customer with written
    notice that Loral has received such bona fide offer. If Customer chooses to
    lease the transponder in question, Customer must respond, in writing, to
    Williams within twenty (20) calendar days of Customer's receipt of Williams'
    written notice and must begin full service on the second transponder no
    later than forty-five (45) days following receipt of Williams' written
    notice. The monthly rate for the second transponder shall

     immediately be [*] without any ramp-up schedule as depicted on Exhibit D
     hereto.  Customer's failure to respond to Williams' notification shall be
     deemed a refusal of the second transponder.  This Right of First Refusal
     terminates when service on the second transponder begins on [*] or when
     Customer declines service under the Right of First Refusal.

(d)  Williams' Standard Satellite Terms and Conditions are attached as Exhibit C
     and are considered an integral part of the Agreement.  In the event of
     conflict, the terms of this Agreement shall supersede the terms and
     conditions in Exhibit C.


5.3  Uplinking/Downlinking. Williams shall modulate Customer's DVB/ASI data
     stream to 70 MHz, upconvert the signal to 14 GHz and then transmit the
     signal from the Teleport to the Transponder in accordance with the
     predicted performance parameters which have been established based on the
     technical specifications calculated in the New York link budget attached as
     Exhibit A-1(a). Customer acknowledges and agrees that any equipment
     substitutions or technical changes made by Customer or Williams may affect
     the attached link budget calculations and could result in corresponding
     changes to the following predicted performance specifications:

     Williams will provide a Primary signal path via its New York Teleport. The
     Customer's signal will be transmitted from New York at a calculated power
     level of 73.11 dBW to TelStar 7's Ku-band transponder 15, resulting in a
     predicted downlink EIRP of 47 dBW per carrier to CONUS. Williams
     understands that this signal will be received by Customer's downlink
     equipment utilizing a minimum 1.0 meter antenna in CONUS providing
     approximately 40 dBi gain at 12 GHz. Calculations are based on Loral Skynet
     provided specifications for TelStar 7. These values assume 6 dB of rain
     fade margin and 99.7% equipment availability. Additionally, these values
     predict an approximate data rate capacity of 39 MBps.

     Williams will provide a Redundant signal path via its Los Angeles Teleport.
     The Customer's signal will be transmitted from Los Angeles at a calculated
     power level of 70.34 dBW to TelStar 7's Ku-band transponder 15, resulting
     in a predicted downlink EIRP of 47 dBW per carrier to CONUS. Williams
     understands that this signal will be received by Customer's downlink
     equipment utilizing a minimum 1.0 meter antenna in CONUS providing
     approximately 40 dBi gain at 12 GHz. Calculations are based on Loral Skynet
     provided specifications for TelStar 7. These values assume 6 dB of rain
     fade margin and 99.7% equipment availability. Additionally, these values
     predict an approximate data rate capacity of 39 MBps.

     When Williams has actual knowledge that there is an outage to Customer's
     Service, Williams must switch signal delivery from the Primary uplink to
     the Redundant uplink as described herein. Williams will switch the signal
     within five (5) minutes upon Williams' actual knowledge of the outage. To
     accommodate Williams' switch of signal delivery, Customer shall maintain
     the delivery of the data signal to the Redundant uplink on a continuous
     basis.

     It is understood and agreed to by both parties that while these initial
     uplink systems do not support iBEAM's long term growth requirements,
     approximately [*] MBps for a CONUS service, but they do provide sufficient
     capacity for iBEAM to develop their service offering. At such time that
     both parties deem this current capacity to be insufficient to meet iBEAM's
     market requirements, both parties will work together to expand these
     systems to support iBEAM's long term growth requirements of [*] MBps. Such
     expansion of Services shall be reflected in an amendment to this Agreement.

              nine (9) days for any thirty-one (31) calendar day period,
              Customer will be required to ramp-up its Service to the data rate
              level for the highest bandwidth actually used during the bursting
              event. For example, if Customer is at 10 MBps, and wants to burst
              to 15 MBps for nine (9) days, then Customer is required to ramp-up
              its fixed data rate to 15 MBps from 10 MBps and begin paying the
              15 MBps rate with no One-Time bursting fee associated with this
              ramp-up. Additionally, any Bursting is limited to 10 MBps above
              the current fixed data rate. If the Bursting requires bandwidth
              greater than 10 MBps higher than the current data rate, Customer
              will be required to raise its current data rate to a level
              supporting the desired bursted bandwidth. All Bursting is limited
              to the bandwidth available within a single transponder. No
              bursting capability is available if bandwidth requires an
              additional transponder.

        (e)   The Service Charge shall be invoiced thirty (30) days in arrears
              and shall be paid by Customer in U.S. Dollars within thirty (30)
              days of the date of invoice. Additionally, at the time of signing
              this Agreement, Customer shall remit to Williams the sum of
              $[*] which sum represents advance payment of one month's
              Service Charge for Transponder 1, to be held by Williams as a
              deposit (the "Deposit") throughout the Term of this Agreement.
              Further, prior to initiation of Service on Transponder 2, Customer
              shall remit to Williams the additional sum of $[*] which sum
              represents advance payment of one month's Service Charge for
              Transponder 2, to be held by Williams as a deposit throughout the
              Term of this Agreement. Such deposits, as are set forth above,
              shall be returned to Customer thirty (30) days from termination of
              this Agreement, provided however that Customer has made payment
              for all services rendered hereunder.

        (f)   Customer agrees that this is a take-or-pay commitment and that
              failure to use the Services throughout the Term does not affect
              Customer's obligation to pay the Service Charge throughout the
              Term. The parties agree that Customer's total commitment pursuant
              to this Agreement through the Term is approximately $8,850,840.
              The parties agree that this take-or-pay commitment is a portion of
              the consideration for this Agreement, and that it is not a
              penalty.

   6.7  Labor. If Williams performs labor for Customer beyond Basic Maintenance
        as described in Section 5.6 herein, at Customer's request, other than in
        connection with the Services, then Customer agrees to pay Williams for
        that labor at the rate of $100 per hour. An example of when a labor
        charge would be charged is if Williams agreed to switch out an item of
        Customer's Equipment with a replacement part provided by Customer.

   6.8  Compliance with Teleport Policies. Customer agrees that it shall comply
        with all policies and procedures of the Teleport.

7. AUTOMATIC RENEWAL.  After the expiration of the Original Term, this Exhibit
   -----------------
A-1 shall automatically renew for one-year renewal terms (a "Renewal Term").
Either party may elect not to renew the Agreement by providing the other party
with written notice a minimum of one hundred twenty (120) days prior to the end
of the Original Term or any Renewal Term.

8. ANNUAL SERVICE CHARGE ADJUSTMENT.  Upon expiration of the Original Term, and
   --------------------------------
   continuing thereafter annually on each anniversary of the Renewal Term of
   this Agreement, unless otherwise agreed to by the parties, the Service Charge
   shall be increased by an amount equal to the Consumer Price Index for All
   Urban Consumers (CPI-U), as originally published by the Bureau of Labor
   Statistics, for all items less food and energy, unadjusted for the twelve
   month period ending the previous December 31.

    Customer shall accept from Williams as specified by Customer on the terms
    and conditions set forth herein.

4.  International Service   Rates for international Communications Services are
    ---------------------
    priced to Customer based on the Exchange Rate at the time service is
    contracted for, subject to monthly adjustments to reflect changes in the
    applicable published Exchange Rate on the first day of each month. Should
    the carrier of non-U.S. Communications Services modify its tariff or the

    Applicable Carrier, its officers, employees or agents, becomes the subject
    of any investigation, or is threatened with or made a party to any
    administrative proceeding or litigation, related to the alleged illegal use
    of the Communications Services by the Customer.

6.  Non-Interference for Satellite Transmissions and Use of Other Communications
    ----------------------------------------------------------------------------
    Services
    --------

    (a) All transmissions to and from the satellite transponder or other use of
        Communications Services made by Customer and/or a Customer Agent in
        connection with use of Communications Services pursuant to this
        Agreement shall comply with all of the rules and regulations of the
        Federal Communications Commission ("FCC"), other governmental agencies,
        carriers or other authorities applicable to Customer and/or each
        Customer Agent with respect to the Satellite Transponder or the
        Communications Services. Customer and each Customer Agent will follow
        the established practices and procedures of the Applicable Carrier for
        frequency coordination and will not utilize the Communications Services
        in a manner which, under standard engineering practice, would or might
        interfere with the use of or cause physical harm to any satellite
        transponder, the satellite or any other communications facility. If, in
        Williams, the Applicable Carrier's or other carrier's judgment,
        Customer's or any Customer Agent's transmissions to or from or
        utilization of the satellite transponder or other Communications
        Services (whether directly or through a Customer Agent), interferes with
        or causes physical harm to any satellite transponder, the satellite or
        any other communications facility, Customer agrees to cease or cause to
        be ceased immediately all transmissions to and utilization of the
        satellite transponder or other Communications Services upon notice
        thereof by Williams or the carrier until such time as such transmission
        or utilization shall not, in Williams' or the carrier's

Standard Form                                                      Page 25 of 26
<PAGE>

          judgment, interfere with and shall not cause physical harm to any
          satellite transponder, the satellite or any other communications
          facility. In such event and in addition to Williams' other rights and
          remedies hereunder, Customer agrees that its rights to use a portion
          of the satellite transponder or other Communications Services in
          accordance with this Agreement shall be subject to Williams' right to
          terminate Communications Services and all of Customer's rights
          hereunder without liability to Customer and to take such action as may
          be necessary, appropriate or desirable to terminate any such
          interference or physical harm by Customer and each Customer Agent.
               (b)  To ensure that Customer and each Uplink/Downlink Agent's
                    transmissions to and from the satellite transponder and
                    Customer's utilization of the Communications Services
                    (whether directly or through an Uplink/Downlink Agent) does
                    not so interfere with or cause physical harm to any
                    transponder or satellite, Customer and each Uplink/Downlink
                    Agent, prior to any transmission to the satellite
                    transponder, must satisfy the uplink access requirements set
                    forth by the Applicable Carrier. Further, without limiting
                    the generality of the foregoing, if Customer's use involves
                    video broadcasting, Customer agrees to comply in all
                    respects with Section 25.308 of the FCC rules regarding the
                    Automatic Transmitter Identification System.

7.   Pre-emptible Nature of Communications Services The satellite transponder
     ----------------------------------------------
     and other Communications Services provided herein are not normally
     protected, other than as provided in Section 8 herein, and may be preempted
     and Customer acknowledges and agrees that it sometimes may be necessary or
     advisable for the Applicable Carrier or other carrier deliberately to
     preempt or interrupt Customer's use of the Communications Services in order
     to protect the overall performance of each satellite, fiber optic network
     or other communications facility, or other technical reasons. Such
     decisions shall be made by the owners or operators of the satellite, fiber
     optic network or other communications facility at their sole discretion and
     Williams shall have no liability to Customer as a result of such decisions.

9.   Fully Protected Transponder. "Fully-Protected" transponders, in the event
     ---------------------------
     of failure, shall be restored by the Applicable Carrier using spare
     equipment that may be available on the satellite at the time of failure, or
     on a comparable transponder on the same satellite, or on another Applicable
     Carrier satellite then in orbit, except when the failure is caused by
     Customer. Fully Protected transponders are not preemptible.

9.   Allowances for Interruption
     ---------------------------
     (a)  Allowances for interruption of Communications Service will be in
          accordance with the Applicable Carrier's Tariff. In the absence of an
          Applicable Carrier's Tariff, Williams' policy shall apply as follows:
          (i) When an interruption of a Communications Service occurs for a
          period of 60 seconds or more, credit is allowed on the basis of 5
          minutes for each 5 consecutive minutes or fraction thereof of
          interruption; (ii) Two or more interruptions occurring during any
          period of 5 consecutive minutes shall be considered one interruption;
          and (iii) An interruption of either the audio or visual portion of the
          television channel shall be considered an interruption of both.
     (b)  An allowance will not be made where Customer fails to transmit or
          receive a television, data or voice channel as a result of, or
          attributable in whole or in part to: (i) Customer's negligence or
          willful acts, or the negligence or willful acts of its officers,
          directors, agents, employees, subsidiaries, parents, affiliates,
          customers, authorized users and viewing subscribers, or any of them;
          (ii) The failure of local channels, transmission lines or equipment
          provided by Customer, its subsidiaries, parents, affiliates,
          authorized users, viewing subscribers, Customer Agents or any of them;
          (iii) Sun outages, heavy precipitation or heavy cloud cover; or (iv)
          Customer's failure to use the channel ordered.
     (c)  In no event shall Williams be liable for allowances for interruption
          unless the claim for such allowance is made within fifteen (15) days
          after the date of the interruption.

10.  Denial of Service   For any violation of the Communications Act of 1934, as
     -----------------
     amended, or any Rules, Regulations or Orders of the FCC or of the terms of
     this Agreement by Customer, or the imposition by the FCC or any
     governmental authority having jurisdiction of conditions on the provision
     of Communications Services which are unacceptable to Williams or the
     Applicable Carrier, Williams may either temporarily deny service or
     terminate the service without incurring liability to Customer.

11.  Cancellation by Customer  Except as specifically provided herein,
     -------------------------
     Communications Service may only be canceled upon the occurrence of all the
     following: written notice to Williams; payment of total hourly, monthly or
     annual charges due for service previously provided and for scheduled
     service that has not been provided as of the date of cancellation; and
     payment of all other sums otherwise due through the term of the Fixed-Term
     Service to be provided pursuant to this Agreement.

12.  Title to Communications Facilities  This Agreement shall not, and shall not
     ----------------------------------
     be deemed to, convey to Customer title of any kind to any of the satellite
     transponders, transponder uplinks/downlinks, fiber optic links, telephone
     lines, microwave facilities or other facilities utilized in connection with
     the Communications Services.

                           SYSTEM SERVICES AGREEMENT


     This System Services Agreement ("Agreement") is made as of January 27,
2000 (the "Effective Date") between America Online, Inc., a Delaware corporation
with its principal office at 22000 AOL Way, Dulles, VA 20166 ("AOL"), and iBEAM
Broadcasting, Inc., a Delaware corporation with its principal office at 645
Almanor Avenue, Suite 100, Sunnyvale, CA 94086 ("iBEAM").  Each of AOL and iBEAM
may be individually referred to herein as a "Party" and collectively, as the
"Parties."

                                    RECITALS

     A.  AOL desires to engage iBEAM to provide iBEAM's content distribution
services (the "Services") to AOL for installation within the areas of the AOL
Network infrastructure as set forth herein and for the purpose of improving
content distribution both within the AOL Network and between the AOL Network and
the Internet (collectively, the "Installation and Distribution Right").

     B.  iBEAM desires to provide the Services to AOL for the purpose of
obtaining access to AOL's Internet bandwidth for use by iBEAM on behalf of its
customers in accordance with the terms of this Agreement, and to provide support
to AOL Users accessing content from iBEAM servers.

     C.  The Parties intend to set forth in this Agreement the terms and
conditions governing iBEAM's provision of the Services and the compensation to
AOL for providing iBEAM with the Installation and Distribution Right.

     THEREFORE, the Parties hereby agree as follows:

     1.  iBEAM Services.  iBEAM will provide the Services using iBEAM servers,
         --------------
which shall be physically located within the AOL host complex (collectively, the
"iBEAM Servers").  iBEAM initially will install the iBEAM Servers within the AOL
host complex using no more than [*] standard equipment racks (each an "Equipment
Rack", and the [*] standard Equipment Racks collectively referred to herein as
the "Obligatory Equipment Rack Space") in each operational AOL data center
(currently in Reston, Virginia, Manassas, Virginia and Dulles, Virginia).  AOL
shall make space in such racks available to iBEAM no later than fifteen (15)
days after the Effective Date (the "Rack Space Availability Date"). The date on
which iBEAM completes the initial installation such that AOL's members have
access to the Media Content (as defined below) shall be known as the
"Installation Date."  iBEAM will retain all right, title and interest in and to
the iBEAM Servers and all iBEAM software and other IBEAM equipment installed on
or used in connection with the iBEAM Servers (other than the Equipment Racks).
The number of iBEAM Servers to be used by iBEAM in providing the Services will
be agreed upon by the Parties as part of the implementation of this Agreement.
If, following the Effective Date, IBEAM requests additional space in the AOL
host complex for further

                                       1

[*] Certain information on this page has been omitted and filed separately
with the Commission. Confidential treatment has been requested with respect to
the omitted portions.
<PAGE>

Equipment Racks (i.e., in addition to the Obligatory Equipment Rack Space), AOL
and iBEAM will discuss terms on which AOL may provide such space to iBEAM. iBEAM
will provide to AOL rolling quarterly forecasts of anticipated space needs
within the AOL host complex, and AOL, in its sole discretion, shall decide
whether to accommodate any such iBEAM request for additional Equipment Rack
space. The Services will facilitate the distribution of (and iBEAM shall be
permitted to use the iBEAM Servers and utilize AOL's Internet bandwidth to send,
receive and deliver) text, software, communications, images, video, sound and
other media or information (collectively, "Media Content"), as follows:

          (a) Media Content will be delivered to members of the AOL Service and
the CompuServe Service (collectively, "AOL Users") through iBEAM Servers (the
"Internal Distribution");

          (b) Media Content will be delivered from the Internet to iBEAM Servers
using AOL's Internet bandwidth ("Inbound Distribution"); and

          (c) Media Content will be delivered from iBEAM Servers to Internet
recipients who are not AOL Users as expressly permitted by the terms of this
Agreement, using AOL's Internet bandwidth ("Outbound Distribution").


     2.  Payments. iBEAM will make the following payments to AOL:
         --------

          (a) Guaranteed Payments. iBEAM shall pay AOL a non-refundable (except
              -------------------
as provided expressly to the contrary in this Section 2 (a) and Section 11 of
this Agreement ) guaranteed payment of Three million Dollars (US$3,000,000), as
follows: (i) One Million Five Hundred Thousand Dollars (US$1,500,000) upon
execution of this Agreement and (ii) One Million Five Hundred Thousand Dollars
(US$1,500,000) upon the earlier of (A) the Installation Date or (B) sixty (60)
days after the Effective Date. The parties acknowledge that if iBEAM terminates
this Agreement due to AOL's failure to provide iBeam with the Obligatory
Equipment Rack Space as required under Section 1, the above payments will be
refundable.

          (b)  Revenue Sharing Arrangement.
               ---------------------------

               (i) If at the end of any calendar quarter during the Term, the
          amounts owed to AOL under subparagraphs (iii) and (iv) below exceed
          the corresponding quarterly minimum dollar amounts set forth below
          (the "Revenue Sharing Threshold"), then iBEAM will pay to AOL the
          amounts owed to AOL under subparagraphs (iii) and (iv) below, less the
          corresponding Revenue Sharing Threshold for the applicable calendar
          quarter. The Revenue Sharing Threshold is as follows:

any previous calendar quarter. The Revenue Sharing Threshold shall apply only to
amounts owed to AOL as a result of Gross Revenues generated in accordance with
subparagraphs (iii) and (iv) below.

     (iii)   Traffic Between AOL Network and the Internet.  Within [*] ([*])
             --------------------------------------------
days following the end of each month of the Term, AOL shall calculate iBEAM's
Monthly Bandwidth Usage, in accordance with Section 9.1 of this Agreement, and
shall notify iBEAM of such usage.  Within [*] ([*]) days following the end of
each month of the Term, iBEAM shall pay to AOL [*] percent ([*]%) of all Gross
Revenues generated from the traffic between the AOL Network and the Internet
during such month on the iBEAM Servers for all traffic up to and equal to the
Maximum Projected Inbound Distribution Bandwidth and Maximum Projected Outbound
Distribution Bandwidth (each as defined in Section 9.3 hereto) (collectively,
the "Minimum Internet Bandwidth Payment"); provided, however, that for each
                                           --------  -------
month in which iBEAM's Monthly Bandwidth Usage equals or exceeds either the
Maximum Projected Inbound Distribution Bandwidth or the Maximum Projected
Outbound Distribution Bandwidth, for such month, iBEAM shall pay to AOL, within
[*] ([*]) days following the end of such month (A) the Minimum Internet
Bandwidth Payment plus  (B) the greater of (1) [*] Dollars (US$[*]) per T-3-
                  ----
equivalent bandwidth for the amount by which the Inbound Distribution traffic
during such month exceeded the Maximum Projected Inbound Distribution Bandwidth
or (2) [*] Dollars (US$[*]) per T-3 equivalent bandwidth for the amount by which
the Outbound Distribution traffic for such month exceeded the Maximum Projected
Outbound Distribution Bandwidth for such month.  . By way of example, if the
Inbound Distribution usage exceeds the Maximum Projected Inbound Distribution
Bandwidth by [*] ([*]) Mbps and the Outbound Distribution exceeds the Maximum
Projected Outbound Distribution Bandwidth by [*] ([*]) Mbps in a particular
month, iBEAM would pay AOL [*] Dollars (US$[*]) per T3-equivalent multiplied by
[*] ([*]) Mbps (rather than $[*] per T3-equivalent multiplied by [*] ([*])
Mbps), in addition to the payment referred to in the preceding clause (A).  For
purposes of this Agreement, (x) "T-3-equivalent" bandwidth shall mean at least
[*] ([*]) Mbps and (y) "Gross Revenues" for a particular month shall mean the
payments billed by iBEAM to its customers during such month for Media Content

delivery services and excluding any sales, excise, export, use and similar
taxes.

     (iv) Traffic Within the AOL Network.  iBEAM shall pay AOL [*] percent
          ------------------------------
([*]%) of all Gross Revenues generated from traffic on the iBEAM Servers located
within or directly attached to the AOL Network (including, without limitation,
the AOL Service and the CompuServe Service) and delivered to AOL Users.

     (v)  Other Stipulations. iBEAM agrees that it will not structure its
          ------------------
customer relationships so as to circumvent (or implement any billing mechanism
that would have the effect of circumventing) the revenue sharing provisions of
this Agreement.

     3.  Purchase of Services by AOL.  AOL may elect during the Term to purchase
         ---------------------------
Services from iBEAM for use in connection with the delivery of Media Content
from AOL's Internet websites (including but not limited to aol.com,
netcenter.com, spinner.com, netscape.com and moviefone.com), pursuant to iBEAM's
standard Service Terms and Conditions, which are attached hereto as Schedule A
to this Agreement. AOL may elect, at its sole discretion, to offset against or
waive iBEAM's payment obligations as set forth in this paragraph in exchange for
AOL purchasing Services in accordance with this Section 3.  AOL's purchase of
iBEAM's Services under this Section will be measured based on Mbps routed over
iBEAM's network, calculated at the "[*]" method, and priced in accordance with
the pricing schedule set forth in the Services Terms and Conditions attached as
Schedule A to this Agreement.

     4.  Warrants. Upon execution of this Agreement and subject to approval by
         --------
iBEAM's board of directors, iBEAM will issue to AOL warrants (in form and
substance satisfactory to AOL) to purchase Five Million Dollars (US$5,000,000)
of iBEAM common stock at a price per share to be mutually agreed upon by the
Parties pursuant to the terms of a warrant agreement to be entered into by the
Parties within thirty (30) days following the Effective Date hereof
(collectively, the "Warrants"). The Warrants shall fully vest upon the earlier
of (i) three (3) years, (ii) the occurrence of any Initial Public Offering, or
(iii) the expiration of this Agreement.  For purposes of this Agreement,
"Initial Public Offering" shall mean a public offering of iBEAM common stock
after the Effective Date that results in proceeds to iBEAM of not less than
twenty million dollars ($20,000,000). The Parties will agree on additional terms
and conditions with respect to the Warrants.

     5.  Media Content Restrictions.
         --------------------------

         (a)  Compliance with AOL Terms of Service. If AOL notifies iBEAM that
              ------------------------------------
     any Media Content delivered to AOL Users violates AOL's Terms of Service
     (which are the terms of service generally applied to AOL Users), iBEAM will
     promptly prevent such Media Content from being routed through the iBEAM
     Servers to the extent technically feasible; provided, however, that if
                                                 --------  -------
     iBEAM is unable to prevent such Media Content from being routed through the
     iBEAM Servers, then AOL may suspend the delivery of such Media Content to
     AOL Users, without penalty, immediately upon notice to iBEAM. AOL may
     modify its Terms of Service from time to time at its discretion; provided,
                                                                      --------
     however, that if AOL makes any material changes or revisions to its Terms
     -------
     of Service, notifications of such material changes or revisions shall be
     posted on the America

     Online service at least thirty (30) days prior to the effectiveness of such
     revisions. The current Terms of Service are available on the AOL Service at
     Keyword: TOS.

         (b)  User Information.  iBEAM shall ensure that iBEAM's collection,
              ----------------
use and disclosure of information obtained from AOL Users under this Agreement
("User Information") complies with (i) all applicable laws and regulations and
(ii) AOL's standard privacy policies, available on the AOL Service at the
keyword term "Privacy" (e.g., no member profiling or data mining). iBEAM will
not disclose User Information collected hereunder to any third party in a manner
that identifies AOL Users as end users of an AOL product or service or use User
Information collected under this Agreement to market another Interactive
Service. For purposes of this Agreement, "Interactive Service" shall mean any
entity offering one or more of the following: (i) [*] (e.g., [*]); (ii) [*]
(e.g., [*] and/or [*] (e.g., [*]); and (iii) [*].

     6.  IBEAM's Responsibilities.  In providing the Services, iBEAM will
         ------------------------
distribute the Media Content to AOL Users exclusively from the iBEAM Servers
located within the AOL complex (subject to capacity restraints), and if AOL at
its sole discretion so requests, iBEAM will promptly provide AOL with
appropriate records to confirm compliance with this obligation.  Notwithstanding
the foregoing, AOL may request that iBEAM distribute Media Content to AOL Users
from other iBEAM servers located outside of the AOL complex (i.e., other than
the iBEAM Servers) in order to address emergency conditions, scheduled
maintenance or capacity constraints based on the number of iBEAM Servers located
within the AOL complex, in which case IBEAM shall do so, to the extent
commercially reasonable (collectively, the "Extraordinary Distribution
Arrangement"); provided, however, that the Media Content served pursuant to any
               --------  -------
such Extraordinary Distribution Arrangement shall not be subject to the revenue
share provisions described in paragraph 2 of this Agreement; provided, further,
                                                             --------  -------
that any resulting increase in Inbound Bandwidth usage is not counted when
measuring Inbound Distribution traffic as described in paragraph 2(b)(iii)(B).
iBEAM acknowledges and agrees that, except as expressly contemplated herein, it
does not require any access to AOL usage data, including but not limited to web
usage logs, to perform its obligations under this Agreement.  iBEAM will ensure
that its iBEAM Servers and Services support and interoperate with the leading
technology in the Internet industry (including, without limitation, [*] caching
servers, [*] and [*] browsers, [*] and [*] streaming software and any other
technology designated from time to time by AOL), and will be responsible for
providing the Services in a professional manner in conformance with industry
standards and the provisions of this Agreement; provided, however, that iBEAM
                                                --------  -------
does not represent or warrant that the Services will be uninterrupted or error
free, and iBEAM's liability in the event of interruptions, errors or failures in
its Services is limited as set forth in Section 10 below.  THE SERVICES ARE
PROVIDED "AS IS" AND IBEAM DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED,
INCLUDING THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
PURPOSE.

     7.  AOL's Responsibilities.  AOL shall be responsible for providing iBEAM
         ----------------------
with the Obligatory Equipment Rack Space to accommodate the iBEAM Servers and
for providing iBEAM with reasonable access to the iBEAM Servers as described in
Section

                                       5

1 above in order for iBEAM to perform its obligations hereunder. AOL shall also
be responsible for supplying iBEAM with information about AOL's Internet
Protocol addressing scheme to the extent necessary for iBEAM to fulfill its
obligations under this Agreement. Notwithstanding the foregoing, AOL does not
represent or warrant that such services will be uninterrupted or error free, and
AOL's liability in the event of interruptions, errors or failures in the
services to be provided by AOL hereunder is limited as set forth in Section 10
below. In addition, the Parties hereby acknowledge and agree that this Agreement
is conditioned upon AOL's ability to permit iBEAM to utilize AOL's bandwidth in
the manner contemplated herein pursuant to AOL's existing arrangements with
third party peering partners. In the event that an AOL peering partner objects
to the use of its bandwidth (as provided to AOL) in accordance with the terms of
this Agreement, AOL shall have the right (without penalty to AOL) to suspend the
delivery of the Media Content through such peering partner's network, provided
that AOL meets its overall commitment to provide bandwidth as specified in this
Agreement. OTHER THAN AS SET FORTH HEREIN, THE SERVICES PROVIDED BY AOL ARE
PROVIDED `AS IS' AND AOL DISCLAIMS ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING
THE WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.

     8.  Technical/Vendor Cooperation.  iBEAM will cooperate with AOL to the
         ----------------------------
extent commercially reasonable in adjusting the capacity of its Services under
this Agreement to adapt to AOL's changing needs, particularly in providing a
favorable browsing environment to AOL Users. In addition, AOL and iBEAM agree to
cooperate with each other to the extent commercially reasonable with a view to
discussing the provision of other value-added services to America Online content
providers and other IBEAM customers, and IBEAM agrees to make commercially
reasonable efforts to integrate the anticipated needs of AOL and its content
partners into IBEAM's future product plans.

     9.  Connectivity Relationships; Bandwidth Usage Calculation.
         -------------------------------------------------------

         9.1.  Reliance on Third-Party Internet Service Providers.  iBEAM
               --------------------------------------------------
acknowledges that AOL's ability to allow iBEAM to use AOL's bandwidth in the
manner set forth herein may, in part, require the approval of one or more third-
party Internet service providers or content partners that have a direct
connection with AOL for such bandwidth. AOL agrees to use commercially
reasonable efforts to obtain such approval; provided, however, that if any such
                                            --------  -------
third party refuses to grant such approval, then AOL may suspend the delivery of
Media Content through such provider's network in AOL's sole discretion, without
penalty, upon reasonable notice to iBEAM provided that AOL meets its overall
commitment to provide bandwidth as specified in this Agreement. The Parties
agree to act in good faith regarding the placement and connectivity of the iBEAM
Servers in the AOL host complex.

         9.2  Measurement of Monthly Bandwidth Usage.  AOL shall separately
              --------------------------------------
measure the amount of Inbound Distribution bandwidth and Outbound Distribution
bandwidth used by iBEAM through the AOL Network infrastructure during each month
of the Term (collectively, the "Monthly Bandwidth Usage"). AOL shall measure
Monthly

                                       6


[*] Certain information on this page has been omitted and filed separately

<PAGE>

Bandwidth Usage according to the "[*]" method, calculated as follows: (i) actual
Monthly Bandwidth Usage in megabit-per-second ("Mbps") will be sampled and
collected every [*] (each, an "Individual Data Point," and collectively, the
"Individual Data Points"), and such Individual Data Points shall be stored for
the remainder of the relevant month; (ii) at the end of each such month, all
Individual Data Points shall be ranked in descending order; (iii) the top [*]
percent ([*]%) of the ranked Individual Data Points shall then be discarded; and
(iv) the highest of the remaining, non-discarded Individual Data Points shall
constitute iBEAM's Monthly Bandwidth Usage.

         9.3  AOL Maximum Projected Monthly Total Bandwidth.  Within two (2)
              ---------------------------------------------
days following the Effective Date, AOL shall supply iBEAM with the maximum
surplus Inbound Distribution bandwidth projected to be available to iBEAM on a
monthly basis during the Term (the "Maximum Projected Inbound Distribution
Bandwidth") and Outbound Distribution bandwidth projected to be available to
iBEAM on a monthly basis during the Term (the "Maximum Projected Outbound
Distribution Bandwidth"), each in Mbps, and as determined by AOL in its sole
discretion (the Maximum Projected Inbound Distribution Bandwidth and the Maximum
Projected Outbound Distribution Bandwidth collectively referred to herein as the
"Maximum Projected Bandwidth", and each individually referred to herein as a
"Component"). AOL will have the right to change the Maximum Projected Bandwidth
(or any Component thereof) from time to time during the Term (as it applies to
subsequent months) upon thirty (30) days' prior notice to iBEAM. Notwithstanding
the foregoing, in no event shall (i) the Maximum Projected Inbound Distribution
Bandwidth be less than [*] ([*]) Mbps or (ii) the Maximum Projected Outbound
Distribution Bandwidth be less than [*] ([*]) Mbps. iBEAM may request from time
to time in writing during the Term an increase in the Maximum Projected
Bandwidth (or any Component thereof), and AOL agrees to respond to iBEAM within
fourteen (14) days following receipt by AOL of any such written request as to
whether or not such request is acceptable to AOL; provided, however, that AOL
                                                  --------  -------
shall not be obligated to provide or make available bandwidth beyond the Maximum
Projected Inbound Distribution Bandwidth (in the case of Inbound Distribution)
or the Maximum Projected Outbound Distribution Bandwidth (in the case of
Outbound Distribution).  The Parties hereby acknowledge and agree that any
bandwidth provided to AOL by iBEAM during the Term shall not constitute part of
either the Maximum Projected Bandwidth in any month of the Term.

     10.  Limitation of Liability.
          -----------------------

          (a)  Liability.  NEITHER PARTY (NOR ITS CUSTOMERS OR MEMBERS) SHALL
               ---------
BE LIABLE TO THE OTHER PARTY (NOR ITS CUSTOMERS OR MEMBERS) FOR PUNITIVE,
SPECIAL, CONSEQUENTIAL, INCIDENTAL, OR INDIRECT DAMAGES, INCLUDING WITHOUT
LIMITATION LOST PROFITS OR LOSS OR DAMAGE TO DATA ARISING OUT OF THIS AGREEMENT,
EVEN IF A PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES
(COLLECTIVELY, "DISCLAIMED DAMAGES"); PROVIDED THAT EACH PARTY WILL REMAIN
                                      --------
LIABLE TO THE OTHER PARTY TO THE EXTENT ANY DISCLAIMED DAMAGES ARE CLAIMED BY A
THIRD PARTY AND ARE SUBJECT TO INDEMNIFICATION PURSUANT TO SECTION 10(c). EXCEPT
AS PROVIDED IN

<PAGE>

SECTION 10(c), (I) LIABILITY ARISING UNDER THIS AGREEMENT WILL BE LIMITED TO
DIRECT, OBJECTIVELY MEASURABLE DAMAGES, AND (II) THE MAXIMUM LIABILITY OF ONE
PARTY TO THE OTHER PARTY FOR ANY CLAIMS ARISING IN CONNECTION WITH THIS
AGREEMENT WILL NOT EXCEED THE AGGREGATE AMOUNT OF FIXED GUARANTEED PAYMENT
OBLIGATIONS OWED BY EITHER PARTY TO THE OTHER PARTY HEREUNDER IN THE YEAR IN
WHICH THE EVENT GIVING RISE TO LIABILITY OCCURS; PROVIDED THAT EACH PARTY WILL
                                                 --------
REMAIN LIABLE FOR THE AGGREGATE AMOUNT OF ANY PAYMENT OBLIGATIONS OWED TO THE
OTHER PARTY PURSUANT TO THE AGREEMENT.

          (b)  No Additional Warranties.  EXCEPT AS EXPRESSLY SET FORTH IN THIS
               ------------------------
AGREEMENT, NEITHER PARTY MAKES ANY, AND EACH PARTY HEREBY SPECIFICALLY DISCLAIMS
ANY REPRESENTATIONS OR WARRANTIES, EXPRESS OR IMPLIED, REGARDING THE SERVICES,
AOL NETWORK, THE AOL SERVICE, AOL.COM, THE COMPUSERVE SERVICE, THE EQUIPMENT
RACKS, THE MEDIA CONTENT OR THE iBEAM SERVERS, INCLUDING ANY IMPLIED WARRANTY OF
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE AND IMPLIED WARRANTIES
ARISING FROM COURSE OF DEALING OR COURSE OF PERFORMANCE. WITHOUT LIMITING THE
GENERALITY OF THE FOREGOING, AOL SPECIFICALLY DISCLAIMS ANY WARRANTY REGARDING
THE PROFITABILITY OF THE iBEAM SERVERS OR THE MEDIA CONTENT.

          (c)  Indemnity. Either Party will defend, indemnify, save and hold
               ---------
harmless the other Party and the officers, directors, agents, affiliates,
distributors, franchisees and employees of the other Party from any and all
third party claims, demands, liabilities, costs or expenses, including
reasonable attorneys' fees ("Liabilities"), resulting from the indemnifying
Party's material breach of any duty, representation, or warranty of this
Agreement.

          (d)  Claims. If a Party entitled to indemnification hereunder (the
               ------
"Indemnified Party") becomes aware of any matter it believes is indemnifiable
hereunder involving any claim, action, suit, investigation, arbitration or other
proceeding against the Indemnified Party by any third party (each an "Action"),
the Indemnified Party will give the other Party (the "Indemnifying Party")
prompt written notice of such Action. Such notice will (i) provide the basis on
which indemnification is being asserted and (ii) be accompanied by copies of all
relevant pleadings, demands, and other papers related to the Action and in the
possession of the Indemnified Party. The Indemnifying Party will have a period
of ten (10) days after delivery of such notice to respond. If the Indemnifying
Party elects to defend the Action or does not respond within the requisite ten
(10) day period, the Indemnifying Party will be obligated to defend the Action,
at its own expense, and by counsel reasonably satisfactory to the Indemnified
Party. The Indemnified Party will cooperate, at the expense of the Indemnifying
Party, with the Indemnifying Party and its counsel in the defense and the
Indemnified Party will have the right to participate fully, at its own expense,
in the defense of such Action. If the Indemnifying Party responds within the
required ten (10) day period and elects not to defend such Action, the
Indemnified Party will be free, without prejudice to any of the Indemnified
Party's rights hereunder, to compromise or defend (and control the defense

                                       8
<PAGE>

of) such Action. In such case, the Indemnifying Party will cooperate, at its own
expense, with the Indemnified Party and its counsel in the defense against such
Action and the Indemnifying Party will have the right to participate fully, at
its own expense, in the defense of such Action. Any compromise or settlement of
an Action will require the prior written consent of both Parties hereunder, such
consent not to be unreasonably withheld or delayed.

     11. Terms and Termination.  The initial term of this Agreement (the
         ---------------------
"Initial Term") shall be two (2) years from the Installation Date (as defined in
Section 1 of this Agreement). The Parties may mutually agree to renew this
Agreement for up to two (2) additional one-year terms (each such additional
term, a "Renewal Term," and together with the Initial Term, collectively
referred to herein as the "Term"). Either Party may terminate this Agreement if
the other fails to cure a material breach of this Agreement within thirty (30)
days of receiving written notice of the breach from the terminating party.
Notwithstanding the foregoing, AOL may terminate the Agreement without penalty
in the event that iBEAM fails to reach Two Hundred Fifty Thousand Dollars
(US$250,000) in Gross Revenues owed to AOL (pursuant to Section 2(b) of this
Agreement) by the first anniversary of the Effective Date ("Insufficient Gross
Revenues Termination"); provided, however, that upon any such Insufficient Gross
                        --------  -------
Revenues Termination, AOL shall refund to iBEAM Two Million Dollars
(US$2,000,000).

     12. Public Relations and Confidentiality. Neither Party shall make or
         ------------------------------------
cause to be made any news release or other public announcement pertaining to
this Agreement or the relationship created hereby or disclose such information
to any third party without the express prior written consent and approval of the
other Party, which will not be unreasonably withheld, except to the extent
required by applicable law, in which case, the disclosing Party shall provide
the other Party with reasonable advance notice of its obligation to make such a
disclosure. The failure by one Party to obtain the prior written approval of the
other Party prior to issuing a Press Release (except as required by law) shall
be deemed a material breach of this Agreement.

     13. Audit Rights.  In making the payments required pursuant to this
         ------------
Agreement, the Party responsible for the same will accompany such payments with
a statement setting forth, in reasonable detail, the basis upon which the
payment has been calculated and the manner of such calculation. Each Party will
keep accurate and complete records supporting such calculation for a period of
at least three (3) years following the date the payment relating to such records
has been made. Each Party agrees to permit such records to be examined, upon
reasonable prior notice but no more than once per year during the Term, by an
independent certified public accountant designated by the Party seeking to audit
the same at such Party's cost in order to determine the accuracy of the reports
and payments made hereunder.  Prompt adjustment shall be made to correct any
errors or omissions in any reports or payments disclosed by any such audit
examination.  In the event that an audit uncovers inaccuracies in payments made
by either Party to the other Party in excess of five percent (5%), the audited
Party agrees to pay for the cost of the audit.  Similarly, AOL will keep
appropriate records supporting its calculation of iBEAM's bandwidth usage

of such records by an independent certified public accountant (on behalf of
iBEAM and at iBEAM's sole cost and expense), and an adjustment shall promptly be
made to correct any errors or omissions disclosed by any such examination.

     14. Confidentiality.  The Parties agree that all disclosures of
         ---------------
confidential and/or proprietary information before and during the Term shall
constitute confidential information (collectively, "Confidential Information")
of the disclosing Party.  Such Confidential Information shall include, but not
be limited to: AOL User and member information, product designs and plans,
architecture and configuration of the AOL Service, source code, the existence of
this Agreement and the relationship created hereby.  Each Party shall use
commercially reasonable efforts to ensure the confidentiality of such
information supplied by the disclosing party, or which may be acquired by either
party in connection with or as a result of the provision of the services under
this Agreement.  Each Party agrees that it shall not disclose, use, modify,
copy, reproduce or otherwise divulge such confidential information other than to
fulfill its obligations under this Agreement, except to the extent required by
applicable law, in which case, the disclosing party shall provide the other
Party with reasonable advance notice of its obligation to make such a
disclosure.  Each Party further agrees to hold  harmless and indemnify the other
Party in the event of any disclosure by such Party.  "Confidential Information"
shall not include information (a) already lawfully known to or independently
developed by the receiving Party, (b) disclosed in published materials, (c)
generally known to the public, or (d) lawfully obtained from any third party.

     15. Change of Control.  "Change of Control" is defined as (a) the
         -----------------
consummation of a reorganization, merger or consolidation or sale or other
disposition of substantially all of the assets of a party or (b) the acquisition
by any individual, entity or group (within the meaning of Section 13(d)(3) or
14(d)(2) of the Securities Exchange Act of 1933, as amended) of beneficial
ownership (within the meaning of Rule 13d-3 promulgated under such Act) of more
than 50% of the outstanding voting securities of the Company or of securities
representing the right to elect a majority of the Company's board of directors.
iBEAM shall not assign this Agreement or any right, interest or benefit under
this Agreement without the prior written consent of AOL, which will not
unreasonably be withheld. Assumption of this Agreement by any successor to iBEAM
(including, without limitation, by way of merger or consolidation) shall be
subject to AOL's prior written approval, which will not unreasonably be
withheld. In the event of any Change of Control of iBEAM or any assignment or
assumption of this Agreement, without AOL's prior written consent, AOL shall
have the right to terminate this Agreement upon written notice to iBEAM. Subject
to the foregoing, this Agreement shall be fully binding upon, inure to the
benefit of and be enforceable by the Parties hereto and their respective
successors and assigns.

     16. Force Majeure.  During the term of this Agreement, neither Party shall
         -------------
be in default of its obligations to the extent that its performance is delayed
or prevented by causes beyond its reasonable control, including but not limited
to acts of God, natural disasters, bankruptcy of a vendor, strikes and other
labor disturbances, acts of war or civil disturbance, or other equivalent or
comparable events.

Business Affairs (fax no. 703-[*]) and the Deputy General Counsel (fax no. 703-
[*]), each at the address of AOL set forth in the first paragraph of this
Agreement.  In the case of iBEAM, except as otherwise specified herein, the
notice address will be the address for iBEAM set forth in the first paragraph of
this Agreement, with the other relevant notice information, including the
recipient for notice and, as applicable, such recipient's fax number or e-mail
address, to be as reasonably identified by iBEAM.

     18. Injunctive Relief.  It is understood and agreed that, notwithstanding

any other provisions of this Agreement, breach of the provisions of this
Agreement by a Party will cause the other Party irreparable damage for which
recovery of money damages would be inadequate and that the non-breaching Party
may therefore seek timely injunctive relief to protect its rights under this
Agreement in addition to any and all remedies at law.

     19. No Agency.  Nothing contained herein shall be construed as creating any
         ---------
agency, partnership, or other form of joint enterprise between the Parties.

     20. Full Power.  Each Party warrants that it has full power to enter into
         ----------
and perform this Agreement and the person signing this Agreement on such Party's
behalf has been duly authorized and empowered to enter into this Agreement. Each
Party further acknowledges that it has read this Agreement, understands it, and
agrees to be bound by it.

     21. Survival.  Sections 10 ("Limitation of Liability"), 12 ("Public
         --------
Relations & Confidentiality"), 13 ("Audit Rights"), 14 ("Confidentiality"), 18
("Injunctive Relief"), 19 ("No Agency"), 21 ("Survival"), and 22 ("Legal
Matters") of this Agreement shall survive cancellation, termination or
expiration of this Agreement.

     22. Legal Matters.  This Agreement represents the entire agreement between
         -------------
the Parties regarding the subject matter hereof.  If any part of this Agreement
is held invalid or unenforceable, that portion shall be construed in a manner
consistent with applicable law to reflect, as nearly as possible, the original
intentions of the Parties, and the remaining portions shall remain in full force
and effect.  The laws of the State of Delaware, excluding its conflicts-of-law
rules, shall govern this Agreement.  The terms and conditions of this Agreement
supercede all previous agreements, proposals or representations related to the
subject matter hereof.
