                               iBEAM BROADCASTING

   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. Streaming is a media distribution
process that allows simultaneous broadcasting and playback of video and audio
content. Our terrestrial and wireless based network uses point-to-multipoint
satellite broadcasting, which is the use of satellite technology to broadcast
streaming content simultaneously to large, geographically dispersed audiences.
Our network broadcasts 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
currently uses 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, ad insertion and business-to-
business communications services.

   The Internet was not designed to support the trafficload 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 more than 50% of websites will include
some streaming media by 2001, a five-fold increase from 1998. Our approach of
using a combination of terrestrial 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.

   Our technology combines broadcast management and control software with e-
commerce capabilities and operates 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
February 29, 2000, our network investment, which we will continue to develop,
is sufficient to support 360,000 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 60 content providers. Launch Media,
Pacific Century Group and NetRadio have been our largest customers in terms of
revenue this year through February 29, 2000, accounting for an aggregate of 35%
of our revenue during this period. Our three largest customers in 1999,
ProWebcast, MusicNow and Pixelworld, accounted for 68% of our revenue during
that period. We generate revenue from our broadcasting services

                                       3
<PAGE>


based on the volume of content stored or delivered to end users and from our
other services such as encoding and event production based on hourly or fixed
price billing. As part of the build-out of our broadcasting network, we have
agreements to locate servers with over 40 ISPs, including America Online, the
largest U.S. Internet access provider, and Covad Communications and Northpoint
Communications, two high-speed Internet access providers that have developed
networks with national reach.

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

 .  Globally Build Out Our High-Fidelity Internet Broadcast Network

 .  Further Leverage Our Broadcast Network to Drive Economies of Scale

 .  Introduce New Value Added Features and Services

 .  Pursue Additional Commercial Relationships and Joint Ventures

 .  Create Open Platform for New Applications

Recent Developments

   Acquisition of webcasts.com

   On March 21, 2000 we entered into a definitive agreement to acquire
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. Webcasts.com's
most significant customers in terms of revenue in 1999 were Lotus/IBM and
America Online.

   The services and tools we gain by acquiring webcasts.com include:

    .  Vuser(TM)--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
       on one interface.

    .  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 will issue approximately 7,993,000 shares of our series F preferred stock
to webcasts.com shareholders and will assume webcasts.com outstanding options
which will convert into approximately 764,000 shares of our series F preferred
stock in connection with the acquisition. The series F preferred stock will
convert into the same number of shares of common stock upon the completion of
this offering. We will also issue a $3.0 million note to webcasts.com's
redeemable preferred stockholders. In addition, the former securityholders of
webcasts.com may receive approximately 1,095,000 additional shares of our stock
if our webcasts.com division meets revenue targets in the twelve months after
the closing of the acquisition.

   Agreement with America Online

   In February 2000, we entered into an agreement with America Online to deploy
our streaming media distribution network within the America Online network. The
agreement will increase 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.
In addition, in February 2000, America Online purchased $5.0 million of our
series E preferred stock, which will convert into 500,726 shares of our common
stock upon the closing of this offering. America Online also 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 $14.00 per share would be
384,024 shares.

   Joint Venture with Pacific Century CyberWorks

   In January 2000, we signed a letter of intent with Pacific Century
CyberWorks Limited, or PCCW, a Hong Kong based Internet services and investment
company, to establish a joint venture company to introduce iBEAM's streaming
media services to its cable customers. This will include deployment and
operation of our servers into ISPs and Internet access providers and
distributing video and audio content from media companies to end users in Asia.
We expect the joint venture, which will be 51% owned by PCCW and 49% owned by
iBEAM, to launch its services by mid-2000. In addition, in February 2000, PCCW
purchased $30.0 million of our series E preferred stock which will convert into
3,004,363 shares of our common stock upon the closing of this offering.

   Investment by The Walt Disney Company


   In March 2000, The Walt Disney Company agreed to purchase $10.0 million of
our series G preferred stock at a purchase price equal to the price of the
common stock to be sold in this offering. The series G 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 $14.00 per share, Walt
Disney will purchase 714,285 shares of our series G preferred stock.

                             SUMMARY FINANCIAL DATA

   The pro forma column in the statements of operations data below gives effect
for the acquisition of webcasts.com, Inc. as if the transaction had occurred on
January 1, 1999. As a result of this acquisition, our historical statements of
operations are not representative of the financial results to be expected for
future periods. See Unaudited Pro Forma Combined Financial Information included
elsewhere in this prospectus.

   Weighted average shares used in computing the pro forma basic and diluted
net loss per share have been calculated assuming the conversion of all
outstanding shares of convertible preferred stock outstanding into common stock
as if the shares had converted immediately upon issuance.

   The pro forma column in the balance sheet data below gives effect to (i) the
conversion of all outstanding shares of our redeemable convertible preferred
stock outstanding as of December 31, 1999 into 62,984,452 shares of common
stock upon the closing of this offering; (ii) the issuance in February 2000 of
2,181,818 shares of series E redeemable convertible preferred stock to PCCW for
$30.0 million and 363,636 shares of series E redeemable convertible preferred
stock to America Online for $5.0 million, and the conversion of those shares
into 3,505,089 shares of common stock; (iii) the pending acquisition of
webcasts.com as if it had occurred on December 31, 1999 and the conversion of
the related issuance of 7,992,961 shares of series F redeemable convertible
preferred stock into the same number of shares of common stock; and (iv) the
issuance in March 2000 of 714,285 shares of our series G redeemable convertible
preferred stock to The Walt Disney Company for $10.0 million at a per share
price equal to the price to the public in this offering and the conversion of
those shares into the same number of shares of common stock. The pro forma as
adjusted column gives effect to the application of the estimated net proceeds
from the sale of 10,000,000 shares of common stock in this offering, after
deducting estimated underwriting discounts and commissions and estimated
offering expenses.

                                 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 are, and the size of our market is,
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.


   In addition, we have entered into an agreement with Microsoft to provide
content providers in Microsoft's broadband streaming initiative with six
months of free service provided that the value of the services to these
participants does not in the aggregate exceed $200,000. Microsoft has not yet
requested that we provide these free services. If they do so, our revenues
would be harmed.

                                       8
<PAGE>

   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. During this year, we expect the deployment of
our network to allow us to provide our services to approximately 50% of U.S.
Internet users 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 and we believe
deployment of our network will reduce incoming data costs for these providers,
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.

   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 due to failure of our network
software. While we are investing in systems and procedures for early detection
of outages and have invested in redundant servers, 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
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.

                                       9
<PAGE>


   Any failure of our network infrastructure or the 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 quality 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;

  .  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 data 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 that 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 over our terrestrial 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-quality streaming video
and audio content.

   Since we commenced offering our services in October 1999 we have
experienced two network outages due to failure of our infrastructure or the
communications services provided to us. 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. 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
our 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.

   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 four market segments:

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

  .  Internet webcasting companies that deliver streaming media through
     terrestrial networks, such as InterVu which has recently been acquired
     by Akamai;

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

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

   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.

                                      11
<PAGE>


   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 whom 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.

   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 any of our commercial relationships terminate, then our business could
be harmed.

   We entered into a commercial relationship with Microsoft Corporation in
September 1999, with Covad Communications in October 1999 and with America
Online in February 2000. Our agreement with Microsoft provides that Microsoft
will recommend us as a critical 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.

   Our agreement with America Online provides that we will deploy our servers
in America Online's facilities throughout 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 Covad provides that we will deploy our servers in
Covad's hubs throughout North America. Considering the size of Covad's network
and market position as a provider of broadband access using 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 with 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 significant 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 throughout 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 with 60 days
notice in the first year of the agreement. In the second

                                      12
<PAGE>


and third years of the agreement, either party may terminate the agreement due
to a material breach by the other. A termination of, or a significant adverse
change in, our relationship with Northpoint could harm our efforts to deploy
our edge servers.

   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
February 29, 2000, our network supported 360,000 simultaneous end users, of
which 40% were served by our edge servers. 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.

   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 our accumulated deficit was $34.2 million as of that date.
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. As of December 31, 1999, we had an accumulated deficit of
$34.2 million. In fiscal 2000, based on the planned deployment of our network,
we expect to have capital expenditures of at least $35.0 million of which
approximately $20.0 million will be spent 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.

                                      13

   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.

   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 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 and prospects depend on consumer demand for streaming video
and audio content over the Internet.

   Consumer demand for streaming video and audio content on the Internet has
only begun to build in recent years, and our success will depend in large part
on the growth in the use of the Internet for these purposes, if any. Market
demand for streaming video and audio content on the Internet is subject to a
high level of uncertainty and is dependant on a number of factors, including:

  .  The growth in consumer access to interactive technologies such as the
     Internet;

  .  The enactment of laws and regulations applicable to content delivery and
     commerce over the Internet;

  .  Consumer acceptance of new interactive technologies; and

  .  Users' demand for bandwidth.

   If the Internet as a source for video and audio content fails to develop or
develops more slowly than expected, our business and prospects will suffer. In
addition, critical issues concerning the use of the Internet, including
security, reliability, cost, ease of access, quality of service, regulatory
initiatives and necessary increases in bandwidth availability, remain
unresolved and are also likely to affect the development of the market for our
services.

   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

                                      14
<PAGE>


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' organization. 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 in our Internet broadcasting. 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 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 pending acquisition of
webcasts.com, and we may face similar risks in the future if we acquire other
businesses or technologies.

   In March 2000, we entered into an agreement to acquire 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
will begin to integrate webcasts.com with our operations after the completion
of the acquisition, which we expect to occur in April 2000. We expect this
integration to place a significant burden on our management team.

   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 impacting our financial results. For example, as a result of the
webcasts.com

                                      15
<PAGE>


acquisition, we will have goodwill and acquired intangibles of approximately
$123.7 million, which will be amortized over three years. 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;

  .  Diversion of management's attention from other businesses concerns;

  .  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.

   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 $35.0 million in capital expenditures, of which $20.0 million
has been spent in the first quarter to date, including investments in edge
servers, data centers and our network operations center, and we expect to
incur significant and increasing losses.

   During the next twelve 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.

   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.

   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
235 on March 10, 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,


                                      16
<PAGE>


  .  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 on 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
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;

  .  The length of the sales cycle for our services;

  .  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.

                                      17

   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 only three services: iBEAM On-Stage, iBEAM On-Air and
iBEAM On-Demand. Sales of our On-Stage service accounted for over 70% of our
net revenue in the quarter ended December 31, 1999. 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
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 December 31, 1999: ProWebCast accounted for 40%, MusicNow, Inc.
accounted for 15% and Pixelworld accounted for 13% of our revenue. 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.

   Two customers accounted for an aggregate of 20.4% of webcasts.com's revenue
in 1999: Lotus/IBM accounted for 14.6% and America Online accounted for 5.8%
of its revenue. The loss of either of these customers or a significant
reduction in the level of webcasts.com's services used by either customer,
could seriously harm our results of operations.

   We expect to amortize stock-based compensation expense over the next four
years, which will decrease our net earnings during this period.

   In connection with the grant of stock options to employees and consultants
in 1998 and 1999, we recorded unearned stock-based compensation of $19.0
million, of which $5.4 million was amortized during 1999. For the period from
January 1, 2000 to February 29, 2000, we issued options to purchase 4,025,906
shares and will record an additional $10.6 million of unearned stock-based
compensation. In addition, in January 2000, we issued to a consultant 908,820
shares of common stock subject to a right of repurchase which lapses over four
years. Based on the fair market value of our common stock at February 29,
2000, this grant will result in an additional $8.3 million of unearned stock-
based compensation, assuming no change in the underlying value of our common
stock. If our stock price increases, the amount of stock-based compensation we
may be required to record would increase. We expect to amortize stock-based
compensation related to these grants and issuance of $16.1 million in 2000,
$9.3 million in 2001, $5.0 million in 2002, and $2.1 million in 2003. 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.


                                      18

   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 recently entered into a
letter of intent with Pacific Century CyberWorks to establish a joint venture
to introduce our services to Asia. In order to bring our services to Asia
under this joint venture we will need to deploy our network of servers in Asia
which will involve large capital expenditures and operating expenses for the
joint venture. While the details of the joint venture have yet to be
determined, we expect to incur approximately 50% of the capital expenditures
and operating expenses of the joint venture. 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 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

   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;

  .  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 37.6% 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 37.6% 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.

   We will have a staggered board of directors, are subject to the "interested
stockholder" provisions of Delaware law and have in place procedures that
proscribe the ability of our stockholders to act without a meeting and limit
the ease with which a stockholder meeting can be called. 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. For a more complete description of
these provisions, see "Description of Capital Stock--Delaware Law and Certain
Provisions of Our Certificate of Incorporation and Bylaws."

   In addition, each of Microsoft, Sony, Pacific Century Cyberworks, American
Online, Covad and Liberty Media, which in the aggregate will own 16.7% 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 and Covad have each also agreed not to acquire more
than 15% of our voting stock at any time before October 2004 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

   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 104,333,927 shares of common
stock outstanding, or 105,833,927 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 certain 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 104,333,927 shares of common stock outstanding after this
offering will be available for resale in the public market as follows:

holders of 75,196,168 shares of the common stock and the holders of warrants
to purchase approximately 1,285,077 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
February 29, 2000, options to purchase 12,151,232 shares of common stock with
a weighted average exercise price per share of $3.50 were outstanding, 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.

   Morgan Stanley & Co. Incorporated at its sole discretion may decide at any
time, without notice, to allow us or any of our stockholders subject to a
lock-up agreement to sell shares of our common stock prior to 180 days from
the date of the prospectus for the offering. We have no agreement with Morgan
Stanley & Co. Incorporated for a waiver of these lock-up restrictions.
However, Morgan Stanley & Co. Incorporated may, in its discretion, release
them. In some cases underwriters have agreed to waive lock-up restrictions
when a company's stock has performed well and market conditions are favorable,
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.


   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 $14.00 per share, if you purchase our common
stock in this offering, you will incur immediate dilution of $11.99 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 February 29, 2000, we had outstanding options to
purchase 12,151,232 shares of common stock at a weighted average exercise
price of $3.50 per share and, on an as converted basis, warrants to purchase
1,796,377 shares of common stock at a weighted average exercise price of $3.93
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 10,000,000 shares of common stock
in this offering at an assumed public offering price of $14.00 per share are
estimated to be approximately $128.5 million, or approximately $148.0 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.

     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 December 31, 1999, was $77.4
million or $0.84 per share of common stock. Our pro forma net tangible book
value per share as of December 31, 1999 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 December 31, 1999 into 62,984,452 shares of common stock upon the
closing of this offering; (ii) the issuance in February 2000 of 2,181,818
shares of series E redeemable convertible preferred stock to PCCW for $30.0
million and 363,636 shares of series E redeemable convertible preferred stock
for $5.0 million to America Online, and the conversion of those shares into
3,505,089 shares of common stock; (iii) the pending acquisition of
webcasts.com as if it occurred on December 31, 1999 and the conversion of the
related issuance of 7,992,961 shares of series F redeemable convertible
preferred stock into the same number of shares of common stock; and (iv) the
issuance in March 2000 of 714,285 shares of our series G redeemable
convertible preferred stock to The Walt Disney Company for $10.0 million at
the price to the public in the offering 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 10,000,000 shares of common stock offered hereby at an
assumed initial public offering price of $14.00 per share, after deduction of
estimated underwriting discounts and commissions and estimated offering
expenses, our pro forma as adjusted net tangible book value at December 31,
1999 would have been $205.9 million or $2.01 per share. This represents an
immediate increase in net tangible book value to existing stockholders of
$1.17 per share and an immediate dilution to new investors of $11.99 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 December 31, 1999. As
of December 31, 1999, there were options outstanding to purchase a total of
9,443,214 shares at a weighted average exercise price of $0.87 per share,
while 3,099,725 shares were reserved for future grants under our 1998 Stock
Plan. As of December 31, 1999, there were warrants outstanding

                                      25
<PAGE>


to purchase 1,412,353 shares of common stock issuable upon exercise and
conversion of outstanding convertible preferred stock warrants at a weighted
average exercise price of $1.19 per share. In February 2000, we granted a
warrant to America Online to acquire 384,024 shares of common stock at per
share exercise price equal to price to the public in the offering, less
estimated underwriting discounts and commissions. From January 1, 2000 to
February 29, 2000, we granted options to purchase an additional 4,025,906
shares of common stock at a weighted average exercise price of $8.86 per share
and will assume all outstanding options granted under webcasts.com's 1999
Stock Option Plan, which will convert into options to purchase 763,646 shares
of series F redeemable convertible preferred stock at a weighted average
exercise price of $3.60 per share. In January 2000, we issued 908,820 shares
of common stock, subject to a right of repurchase, at $4.84 per share to a
consultant. To the extent there are exercises of any of these options, there
will be further dilution to new investors. See "Capitalization," "Management--
Compensation of Directors," and "--Executive Compensation."

                    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 March 2000 we entered into an agreement to acquire
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 December 31, 1999, we had an accumulated deficit
of $34.2 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.

   We will issue 7,992,961 shares of our series F preferred stock to
webcasts.com's security holders in connection with the acquisition and will
assume webcasts.com's outstanding options which will convert into 763,646
shares of our series F preferred stock. We will also issue 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 1,095,000 shares of
stock if our webcasts.com division meets certain revenue targets in the twelve
months after the closing of the acquisition.

   As result of the acquisition, we expect to expect to incur merger-related
costs of up to $1.7 million and to record approximately $123.7 million of
intangible assets and goodwill on our balance sheet, which will result in
amortization expense of approximately $30.9 million in 2000, $41.2 million in
2001 and 2002 and $10.4 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 services that
include encoding, production and event management, custom Web integration with
chat and e-commerce tools, and broadcasting content to Internet users. We
expect broadcasting services to provide the largest and fastest growing
revenue element of our services.

   Our broadcasting services are charged based on the volume of content stored
or delivered to end-users as measured in megabytes or megabits consumed and
therefore varies with the number of users, the access speeds

                                      29
<PAGE>


of the users and time users spend viewing content broadcast by us. On-Air and
On-Stage services are typically priced based on peak usage, which is the
maximum megabits delivered per second per month, while On-Demand services are
typically priced based on actual usage, which is the total amount of megabits
transferred during the month. Other services such as encoding, event
production and management, customization and integration with e-commerce tools
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 operations monitoring center. The cost of other
services such as encoding, event management and customization 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 terrestrial communication
land lines. In proportion, the largest direct cost is terrestrial land lines.
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
terrestrial landline costs. Therefore it is our goal to increase the amount of
content we deliver to the edge of the Internet. 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. Some of
the ISPs to which we deliver content have negotiated access fees, however
these fees have represented lower costs to iBEAM than paying for terrestrial
landlines. The fees we pay to ISPs are based on a percentage of revenue
derived from content delivered through their network, ranging from 15% to 20%.

   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 calendar 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.

   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.

   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
in 1998 and 1999, we recorded unearned stock-based compensation of $19.0
million, representing the difference between the deemed fair value

                                      30
<PAGE>


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. We expect to amortize unearned stock-based compensation of $7.7
million in 2000, $3.7 million in 2001, $1.6 million in 2002 and $0.6 million
2003.

   For the period from January 1, 2000 to February 29, 2000, we issued options
to purchase 3,943,286 shares to employees at a weighted average exercise price
of $8.86 per share. In connection with such grants, we will record an
additional $10.6 million of unearned stock-based compensation. In addition, in
January 2000, we issued 908,820 shares of common stock subject to a right of
repurchase, to a consultant, which lapses over four years. Based on the fair
market value of our common stock at February 29, 2000, this grant will result
in an additional $8.3 million of unearned stock-based compensation, assuming
no change in the underlying value of our common stock. We expect to amortize
additional stock-based compensation expense related to these grants and
issuances of $8.4 million in 2000, $5.6 million in 2001, $3.3 million in 2002,
and $1.6 million in 2003.

   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.

iBeam's Results of Operations for 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.

   The following table summarizes operating costs and expenses, excluding the
non-cash amortization of stock-based compensation of $39,000 in 1998 and $5.4
million in 1999 (in thousands):

</TABLE>

   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

                                      31
<PAGE>


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 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 higher 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, 1999 and
December 31 1998

   Webcasts.com was incorporated in 1995 and commenced its current Web
production services business in 1997. 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 $.9 million to $4.3 million primarily due to increased
selling expenses partially as a result of its acquisition of the Rock Island
Group, Inc. and stock-based compensation. As of December 31, 1999,
webcasts.com had an accumulated deficit of $4.1 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 $61.2 million from the sale of our preferred stock.

   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

                                      32
<PAGE>

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 February 29, 2000, we had approximately $41.3 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 February 2000 we have raised $96.0 million from
the sale of preferred stock and $8.5 million from equipment lease lines that
are repayable over three years. We expect to make at least $35.0 million in
capital investments in 2000, of which $20.0 million has been 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 twelve to eighteen months.
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,
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 February 29, 2000 we have not experienced any significant issues 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

                                      33
<PAGE>


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 believe that the impact of SAB No. 101
will have no material effect on our financial position or results of
operations.

                                   BUSINESS

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. Our terrestrial and
wireless based network uses 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 uses iBEAM
servers located in the facilities of Internet service providers, or ISPs and
other companies which host Internet applications and services.

   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, ad insertion and business-to-business
communications services.

   Our technology combines broadcast management and control software with e-
commerce capabilities and operates with a variety 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 February 29, 2000, our network investment, which we will
continue to develop, is sufficient to support 360,000 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 60 content providers. Launch Media,
Pacific Century Group and NetRadio have been our largest customers in terms of
revenue this year through February 29, 2000, accounting for an aggregate of
35% of our revenue during this period. Our three largest customers in 1999,
ProWebCast, MusicNow and Pixelworld, accounted for an aggregate of 68% of our
revenue during that period. 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 40 ISPs including America Online,
the largest U.S. Internet access provider, and Covad Communications and
Northpoint, two high-speed Internet access providers which have developed
networks with national reach.

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 quality 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 and music file
before viewing or listening.

   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 tour of a product, combined with the interactive

                                      35

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 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 on-line 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, 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 use of
many forms of entertainment.

   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 format (user datagram protocol) 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 increasing the traffic
load on the Internet causing further congestion and quality degradation. These
two characteristics, 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 bandwith, 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 which approaches the quality of a VCR video (a 300 kilobit
stream) would typically exceed advertising revenue derived by the content
provider from such transmission. 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, 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 Solutions

   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 solution 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 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 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
provide a complete solution for large scale, high fidelity Internet
broadcasting. Our Internet broadcast network leverages the best attributes of
many of these solutions and combines them with our proprietary streaming
software to deliver a cost effective streaming media broadcasting solution
that offers high fidelity content distribution to large numbers of
simultaneous users.

The iBEAM Solution

   We provide a global Internet broadcast network that delivers streaming
media with viewing and listening quality that approaches television and radio.
Our broadcast network offers content providers the ability to serve large
audiences of simultaneous users. Our network uses a combination of terrestrial
networks and satellite broadcasting to deliver Internet content to iBEAM
servers located at the edge of 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 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 encoding, event management and e-commerce 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 software and network
     architecture 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 a combination of terrestrial networks and
     satellites 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 satellites to transmit a single stream to an unlimited
     number of servers, allow us to serve large audiences of simultaneous
     users. As we add streaming capacity through additional investments in
     servers and data 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 solution for content providers comprises, among
     other things, event planning, encoding and acquisition 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 event production, encoding
     and monitoring 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 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

                                      38
<PAGE>

     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 for the entertainment, media
and business markets. 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 60 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 (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 will expand our
customer base by adding customers who 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 are 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 North American explosion of
Internet and data related transmission growth 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 to
establish a joint venture company called iBEAM Asia. iBEAM Asia will focus on
deploying our servers into ISPs in Asia as well as distributing video and
audio content in Asia. We expect the joint venture, which will be 51% owned by
PCCW and 49% owned by iBEAM, to be operational by mid-year 2000. 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 allows a number of standard
Internet applications to be run across a global network of distributed edge
servers. The inherent advantage of our network and its associated broadcast
software platform is its ability to allow standard Internet applications to
reach large audiences. Because we have deployed a point-to-multipoint network
architecture, we are 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.

                                      39
<PAGE>


   Introduce New Value Added Features and Services. In addition to offering
high-quality streaming performance 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 intend to pursue is the introduction of targeted streaming
advertising into our edge-delivered broadcast. Our servers may eventually have
the capability to locally insert directed advertisements into each copy of the
broadcast stream it serves. 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. By the second half of 2000, we
expect to be able to insert streaming advertising which will be targeted at
the end user based on the geographic location of the user and the nature of
the website the user is visiting. Although we have not yet developed a pricing
structure for these services, we do expect to generate revenue from targeted
advertising in the future. 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 Pacific Century Cyberworks, America Online,
Microsoft, Covad Communications 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, who 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 further
secure our strong 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 the efficiencies 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. All services are priced on a monthly usage basis, with
typical prices ranging from $500-$1,000 per megabit per second for one month
depending on volume commitments. Content providers are charged for the
bandwidth served by us to end users.

   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 occasional or event-based customer.
Target customers for iBEAM On-Stage include concerts, trade

                                      40
<PAGE>


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 intelligent network agent iDirector that manages the
replication of stored on-demand content across the array of iBEAM MaxCaster
servers. iBEAM On-Demand files are typically broadcast to the remote
MaxCasters using our satellite backbone. 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 event management, encoding and
acquisition services. These services are typically billed on a consulting or
usage basis.

   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. We have a team of event managers that will travel on-site
for high profile 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 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 60 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 February 29, 2000:

     Sport Vision                            Technimedia

   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.

   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. 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
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.

   MSNBC

   MSNBC utilizes the satellite delivery of iBEAM On-Air, as well as the high
quality edge delivery of iBEAM On-Demand. MSNBC's continuous live video news
feed is streamed over our satellite network. We also use the satellite to
deploy and update news highlights that are available on-demand to MSNBC users.
In December 1999, a single 100 kilabit 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 terrestrial 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 40 ISP 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 which charge ISPs
for delivery of content. Furthermore, in some cases, we share a portion of our
revenue derived from content providers with the ISP.

                                      42
<PAGE>


   In addition to our network of MaxCaster edge servers, we have deployed a
series of regional data centers. The regional data 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 data centers
provide a second tier of redundancy--if the MaxCaster is unavailable for any
reason, users are automatically routed to our nearest regional data center.


   The third layer of redundancy in our network is achieved by the deployment
of master data centers, are located in co-location facilities of companies
such as Abovenet and Exodus Communications. The master data centers provide a
third layer of redundancy, filling in for any regional data 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.

   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 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 terrestrial 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 February 29, 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
intelligently process the content to perform functions, such as inserting
streaming advertising that is targeted to each individual 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 a user types

                                      43
<PAGE>

www.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. All of this routing happens transparently to the end user.
The end user is only aware that she typed www.msnbc.com and received a high
quality, uninterrupted video stream.

Acquisition of webcasts.com

   On March 21, 2000 we entered into a definitive agreement to acquire
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.

   Webcasts.com's service and tools offerings include:

    .  Vuser(TM)--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;

    .  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 solution to
customers, intended to making 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
17, 2000.

Commercial Relationships

   We have commercial relationships with America Online, Pacific Century
Cyberworks, Covad Communications, InterPacket, Microsoft Corporation, and Sony
Corporation, and intend to enter into additional relationships with 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.



   America Online

   In February 2000, we entered an agreement with America Online to deploy our
streaming media distribution network within the America Online network. 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.

   In addition, in February 2000, America Online purchased $5 million of our
series E preferred stock which will convert into 500,726 shares of common
stock upon the closing of the offering and 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 $14.00 per share would be
384,024 shares.

                                      44

   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 to introduce iBEAM's streaming media
services to its cable customers. The joint venture will include deployment and
operation of MaxCaster servers into ISPs and Internet access providers and
distributing video and audio content from media companies to end users in the
over 50 countries in Asia served by PCCW. We expect the joint venture, which
will be 51% owned by PCCW and 49% owned by iBEAM, to be operational by mid-
year 2000.

   In addition, in February 2000, PCCW purchased $30 million of our series E
preferred stock which will convert into 3,004,363 shares of our common stock
upon the closing of this offering.

   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 streaming video and
audio content at lower cost than landline communication providers. Under the
terms of the agreement, we will deploy our MaxCaster servers in Covad hubs 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.

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

   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. InterPacket realizes revenue through delivering our streaming
content, and we benefit by accelerating international deployment of our
network to the edge of the Internet.

   Microsoft Corporation

   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 critical 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 each content provider that is a participant in
Microsoft's broadband streaming initiative, provided that the value of these
services to such participants does not exceed $200,000 in the aggregate. 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.

   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 purchased shares of our series D preferred stock 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

                                      45
<PAGE>


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.

   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.

   Sony purchased shares of our series D preferred stock 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 January 25, 2000, we had 25 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.

   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 three systems engineers and
five 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.

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.

                                      46
<PAGE>

   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 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, with a combination of satellite and terrestrial enabled
streaming media as our primary business mission.

   Our competitors primarily come from three market segments:

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

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

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


                                      47
<PAGE>

   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 59,000 square feet
of leased office space in Sunnyvale, California. We recently obtained an
additional 23,000 square feet of office space near our headquarters.

   We are building a network operations center in our headquarters which we
believe will be completed by April 2000. We have budgeted $4.0 million for
this purpose, of which $500,000 was spent as of December 31, 1999.

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

Employees

   As of February 29, 2000 we had a total of 235 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 on 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 $35.0 million in 2000 for capital expenditures, $20.0 million
of which will be spent in the first quarter to date. 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, data 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 which 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 $10.0 million and seeks a determination from the Court that he is
entitled to shares of our capital stock. Based on our investigation to date,
we believe Mr. Chew's lawsuit is without merit and we intend to defend the
action vigorously. Litigation is inherently uncertain, however, 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.

consisting of each class is as follows:

<TABLE>
<CAPTION>

</TABLE>

   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.
Some of our non-employee directors have received grants of options to purchase
shares of our common stock. See "Principal Stockholders"

                                      54
<PAGE>


and "Certain Relationships and Related Transactions--Option Grants to Certain
Directors." 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.

   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
14,983,492 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
reassessed fair market value of our common stock on December 31, 1999. Amounts
reflected are based on the value of $5.81 per share, minus the per share
exercise price, multiplied by the number of shares underlying the option.

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
shall be entitled to receive up to 12 months of annual salary until the
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
service with us or our successor corporation for a period not to exceed six
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 perfomance goals. The offer
letter provides that options granted to Mr. Dier in connection with his
employment will provide for accelerated vesting in the event of a

                                      58
<PAGE>


change of control where Mr. Dier is not designated as Chief Financial Officer
reporting to the Chief Executive Officer equal to an amount of 50% of Mr.
Dier's unvested shares. In addition, Mr. Dier will receive a termination
payment equal to six months full compensation payable on the earlier of six
months after a change of control or termination of employment by the acquiring
company.

   Nils Lahr. In July 1999, Nils Lahr accepted our offer of employment. The
offer letter provides that Mr. Lahr is entitled to receive an annual salary of
$150,000 and a bonus of $30,000 based on achievement of performance
milestones. Mr. Lahr has agreed to be employed by us through June 30, 2000, at
which time he will become an at-will employee. We may terminate his employment
with us at any time.

   Jeremy Zullo. In July 1999, Jeremy Zullo accepted our offer of employment.
The offer letter provides that Mr. Zullo is entitled to receive an annual
salary of $155,000 and a bonus of $20,000 based on the achievement of
performance milestones. Mr. Zullo has agreed to be employed by us through June
30, 2000, at which time he will become an at-will employee. We may terminate
his employment with us at any time.

   On September 24, 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 February 29, 2000, we had reserved an aggregate of 23,195,049 shares
of our common stock for issuance under this plan, of which options to purchase
12,151,232 shares of common stock were outstanding and 653,214 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 we expect to submit the plan to our stockholders for approval in April
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 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,

  .  5,508,000 shares, or

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


                                      59
<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. 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 688,500 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, 1,927,800
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.


                                      60
<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 November 1 and May 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 October 31, 2000.

   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 and commissions but excluding
all other compensation paid to our employees. 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. 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 we expect to submit the plan to our stockholders for approval in
April 2000. As of March 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
becomes 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. After termination as a
non-employee director with us, an optionee must exercise an option at the time
set forth in his or her option agreement. If termination is due to death or
disability, the option will remain exercisable for 12 months. In all other
cases, the option will remain exercisable for a period of 6 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.

                                      61
<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 3 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 90 days following the date of the notice. The
option will terminate upon the expiration of the 90-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

   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. Our founders include

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. Wilmott continues to serve as our employee or consultant. In
connection with the formation of our company, Mr. Wilmott 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 a 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 monthly 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.

   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. In connection with this agreement, Mr. Seegal purchased
908,820 shares of our common stock which are subject to our right of
repurchase. Our repurchase right lapses with respect to 12.5% of the shares
six months from the date of the purchase and our repurchase right lapses with
respect to 1/48th of the remaining shares each month thereafter. We loaned Mr.
Seegal $1,999,998 to apply to the purchase price for these shares. This loan
is evidenced by a full recourse promissory note in our favor.

   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 critical 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 each content provider that is a
participant in Microsoft's broadband streaming initiative, provided that the
value of these services to such participants 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 20,
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 February 29, 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 94,333,927 shares outstanding as of
February 29, 2000, assuming conversion of the preferred stock, and 104,333,927
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 February 29, 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
300,000,000 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 February 29, 2000, there were 94,333,927 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 254
stockholders. This number includes:

 .  66,489,541 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;

 .  7,992,961 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; and

 .  714,285 shares of our series G preferred stock to be issued to The Walt
    Disney Corporation for $10.0 million at a price equal to the public in the
    offering and the conversion of these shares into the same number 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 February 29, 2000, there were warrants
outstanding to purchase a total of 1,796,377 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.

                                      68
<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 384,024 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 75,196,788 shares of
common stock and the holders of warrants to purchase approximately 1,285,077
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

                                      69
<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 and Covad 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 16.7% 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 104,333,927
shares of common stock, assuming the issuance of 10,000,000 shares of common
stock offered by us and no exercise of options outstanding after February 29,
2000. All of the 10,000,000 shares sold in this offering 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.

   The remaining 94,333,927 shares of common stock held by existing
stockholders were issued and sold by us in reliance on exemptions from the
registration requirements of the Securities Act. 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, 82,121,591 shares will
become eligible for sale pursuant to Rule 144(k), Rule 144, and Rule 701.
Thereafter, 12,212,336 shares will become eligible for sale pursuant to Rule
144.

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 1,043,339 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

                                      71
<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 75,196,788 shares of common stock and the holders of warrants to
purchase approximately 1,285,077 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.

Stock Options

   As of February 29, 2000, there were a total of 12,151,232 shares of common
stock subject to outstanding options under our 1998 Stock Plan, 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, certain of the participants in the directed share
program, as described in the section entitled "Underwriters," will be subject
to similar lock-up restrictions.

   Morgan Stanley & Co. Incorporated at its sole discretion may decide at any
time, without notice, to allow us or any of our stockholders subject to a
lock-up agreement to sell shares of our common stock prior to 180 days from
the date of the prospectus for the offering. We have no agreement with Morgan
Stanley & Co. Incorporated for a waiver of these lock-up restrictions.
However, Morgan Stanley & Co. Incorporated may, in its discretion, release
them. In some cases underwriters have agreed to waive lock-up restrictions
when a company's stock has performed well and market conditions are favorable,
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 1,500,000
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. Among the 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 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        shares offered hereby for directors,
officers, employees, business associates, and related persons 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 purchased will be offered by the underwriters to the
general public on the same basis as the other shares offered hereby.

   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. Among the 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.

                       REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors and Stockholders of
 iBEAM Broadcasting Corporation

   The stock split described in Note 2 to the financial statements has not been
completed at March 20, 2000. When it has been completed, we will be in a
position to furnish the following report:

     "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 1999 and for the year
  ended 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."

                         (a development stage company)

                         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.

   The Company is 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
includes 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

   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.

                         (a development stage company)

                  NOTES TO FINANCIAL STATEMENTS--(Continued)


   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:

   <S>                                           <C>

                                                  the estimated useful life

   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.

   Revenue recognition

   The Company derives revenue from the sale of its services under contracts
with terms typically ranging from a single event to a service period of three
to twelve months. These contracts may also provide for minimum monthly fees.
Distribution services are billed based on the volume of content stored or
delivered to end-users and revenue from other services are billed based on
time incurred. The Company recognizes revenue as services are performed.

   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.

   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 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.

   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
ration. The pro forma effects of this transaction is unaudited and has been
reflected in the accompanying Pro Forma Stockholders' Equity as of December
31, 1999.

   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.
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.

   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. 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,

   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:

     Pro forma......................................      (0.56)         (3.52)
</TABLE>

   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 and $17,290,000 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 and for the year ended December 31,
1999, 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 and $4,974,000 for the period from
March 20, 1998 (inception) to December 31, 1998 and for the year ended
December 31, 1999, respectively, and expects to amortize stock-based
compensation of $7,313,000 in 2000, $3,491,000 in 2001, $1,533,000 in 2002 and
$556,000 in 2003.

   Stock-based compensation expense related to stock options granted to
consultants is recognized as the stock options are earned. At each reporting
date, the Company re-values 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. In connection with the grant of stock options to consultants, the
Company recorded stock-based compensation expense of $8,000 and $419,000 for
the period from March 20, 1998 (inception) to December 31, 1998 and for the
year ended December 31, 1999, respectively. As of December 31, 1999, the
Company expects to amortize stock-based compensation expense of $720,000 over
future periods assuming no change in the underlying value of the Company's
common stock.

   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.

fully-diluted capitalization of the combined companies immediately following
the acquisition. Using the capitalization of the companies as of February 29,
2000, the Company expects to issue 7,992,961 shares, at $14.00 per share, for
a value of approximately $111.9 million. In addition, based on an exchange
ratio of 0.3419 shares of iBEAM for every share of webcasts.com, all of the
outstanding options granted under the webcasts.com 1999 Stock Option Plan will
be converted into options to purchase 763,646 shares of the Company's Series
F. The fair value of these options of approximately $9.0 million was
determined using the Black-Scholes option pricing model and is included as a
component of the purchase price. The Company will also issue a $3.0 million
note to the webcasts.com's redeemable preferred stockholders, which is payable
on September 30, 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 January 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 against future revenue sharing obligations. 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
redeemable convertible preferred stock ("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 384,024 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 $3.1 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.

   Pacific Century CyberWorks (PCCW)

   The Company have entered into an agreement with Pacific Century CyberWorks
Limited (PCCW) to establish a joint venture company that will bring high-
fidelity streaming audio and video to Asia. The new company, to be called
iBEAM Asia will be responsible for extending the Company's current business
and services to Asia. This will include deployment and operation of MaxCaster
servers into ISPs and Internet access providers and distributing video and
audio content from media companies to end users in over 50 countries in Asia.
The joint venture will be 51% owned by PCCW and 49% owned by iBEAM and is
expected to be operational by mid-year 2000. The joint venture will be
accounted for under the equity method of accounting. In addition, in February
2000, PCCW purchased $30 million of Series E for $13.75 per share.

   RealNetworks, Inc.

   In February 2000, the Company entered into a seven-year Infrastructure
Software License Agreement with RealNetworks, Inc. for an initial payment of
$10 million for the G2 streaming software platform. Additionally, the Company
has agreed to pay RealNetworks a quarterly royalty, subject to certain annual
minimum and maximum payments. The aggregate future minimum payments under the
agreement are $15 million.

   Stock option plans

   The Company's 2000 Stock Plan (the "2000 Plan") was adopted by the Board of
Directors, subject to stockholder approval, in January 2000. The 2000 Plan
provides for the grant of incentive stock options to employees and non-
statutory stock options and stock purchase rights to employees, directors and
consultants.

   A total of 9,639,000 shares of common stock were reserved for issuance
pursuant to the 2000 Plan. No options have yet been issued. The number of
shares reserved for issuance under the 2000 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,

  .  5,508,000 shares or

  .  such lesser amount as determined by the Board of Directors.

   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"). A total
of 688,500 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) 1,927,800 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 November 1 and May 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 October 31, 2000. The Purchase 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 and commissions but excluding all other compensation paid to our
employees. 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.

   For the period from January 1, 2000 to February 29, 2000, we issued options
to purchase 4,025,906 shares to employees at a weighted average exercise price
of $8.86 per share. In connection with such grants, we will record an
additional $10.6 million of unearned stock-based compensation.

   Common Stock

   In January 2000, we issued 908,820 shares of common stock, subject to a
right of repurchase which lapses over four years, to a consultant. At February
29, 2000, this grant resulted in an additional $8.3 million of unearned stock-
based compensation, assuming no change in the underlying value of our common
stock.

              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 with 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.

   Under the terms of the agreement, all issued and outstanding shares and
warrants of webcasts.com will be exchanged for shares of the Company's series
F redeemable convertible preferred stock ("Series F") equal to 8% of the
fully-diluted capitalization of the combined companies immediately following
the acquisition. Using the capitalization of the companies as of February 29,
2000, the Company expects to issue 7,992,961 shares, at $14.00 per share, for
a value of approximately $111.9 million. In addition, based on an exchange
ratio of 0.3419 shares of iBEAM for every share of webcasts.com, all of the
outstanding options granted under the webcasts.com 1999 Stock Option Plan will
be converted into options to purchase 763,646 shares of the Company's Series
F. The fair value of these options of approximately $9.0 million was
determined using the Black-Scholes option pricing model and is included as a
component of the purchase price. The Company will also issue a $3.0 million
note to the webcasts.com's redeemable preferred stockholders, which is payable
on September 30, 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
1,095,000 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 $125.6 million was 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 a preliminary 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 analysis of the total purchase price and fair value of the
assets acquired and liabilities assumed. The aggregate purchase price has been
allocated as follows (in thousands):

                                                                       $125,624
                                                                       ========
</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
December 31, 1999 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 December 31, 1999 and combines the balance
sheet of iBEAM as of December 31, 1999 and the consolidated balance sheet of
webcasts.com as of December 31, 1999.

   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 record the incremental goodwill and the acquired intangibles of
     $119.7 million to webcasts.com's existing amount of $3.9 million such
     that the combined goodwill and acquired intangibles totaled $123.7
     million as described in the overview.

  B  To reflect the anticipated acquisition related expenses of approximately
     $1.7 million.

  C  To reflect the conversion of the note payable to redeemable preferred
     stock in February 2000 and the issuance of a $3.0 million note payable
     by iBEAM to webcasts.com's redeemable preferred stockholders as
     additional consideration.

  D  To reflect the issuance of 7,992,961 shares of Series F at $14.00 per
     share and the assumption of options to purchase 763,646 shares of Series
     F valued at approximately $9.0 million.

  E  To eliminate historical equity accounts of webcasts.com.

  F  To record the additional amortization of goodwill and acquired
     intangibles related to the acquisition of webcasts.com as if the
     transaction occurred on January 1, 1999. Goodwill of approximately
     $113.4 million and acquired intangibles of approximately $10.3 million
     are being amortized on a straight-line basis over three years.

  G  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.

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

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


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

  J  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.

  K  Pro forma basic and diluted net loss per share for the year ended
     December 31, 1999 is computed using the weighted average number of
     common shares outstanding, including the pro forma effects of the
     automatic conversion of the Company's Series A, B, C and D 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 18,721,000 shares,
     have been excluded from the diluted net loss per share calculation
     because to do so would be antidilutive.

The Board of Directors and Shareholders
webcasts.com, Inc.

   We have audited the accompanying consolidated balance sheets of
webcasts.com, Inc. and subsidiary as of December 31, 1999 and 1998, and the
related consolidated statements of operations, stockholders' equity (deficit),
and cash flows for the years then ended. These consolidated financial
statements are the responsibility of the Company's management. Our
responsibility is to express no opinion on these consolidated financial
statements based on our audits.

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

   In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of
webcasts.com Inc., and subsidiary as of December 31, 1999 and 1998, and the
results of their operations and their cash flows for the years then ended in
conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(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.

   (b) Principles of Consolidation

   The consolidated financial statements include the accounts of webcasts.com,
Inc. and its 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 due to the short-
term nature of the contracts. Revenue is recognized upon completion of the
contract and contract 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.

   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

                                     F-30
<PAGE>

                       WEBCASTS.COM, INC. AND SUBSIDIARY

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

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
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

                                     F-31
<PAGE>

                       WEBCASTS.COM, INC. AND SUBSIDIARY

                  NOTES TO FINANCIAL STATEMENTS--(Continued)

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.

(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 (goodwill) was approximately
$4 million and is being amortized on a straight-line basis over 7 years.

   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

                                     F-32
<PAGE>

                       WEBCASTS.COM, INC. AND SUBSIDIARY

                  NOTES TO FINANCIAL STATEMENTS--(Continued)

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

   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 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 Loan Warrants) and the recorded value is net of amounts allocated to
the Bridge Loan Warrants. The debt has increased approximately $31,100 for the
accretion of the debt to its face value as of December 31, 1999. If the
Company consummates a private placement of equity securities in an amount not
less than $10,000,000 (Qualified Transaction) the holders of the promissory
notes have the option to exchange the notes for the securities issued in the
transaction on the same basis as the other cash investors in the private
placement.

(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 an aggregate of 7,756,243 detachable warrants to purchase common stock
(Preferred Warrants), for approximately $3,000,000.

                       WEBCASTS.COM, INC. AND SUBSIDIARY

                  NOTES TO FINANCIAL STATEMENTS--(Continued)

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, cumulative dividends in arrears for the Preferred Stock were
approximately $120,000. 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 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
Warrants expire in May 2009 and approximately 1,501,000 of the 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 anytime 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.

(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 shareholders 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 shareholders.
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 20,000 options to purchase the 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, cumulative dividends in arrears for the
Series D Stock were approximately $53,000. The

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

holders of the Series D Stock have voting rights equivalent to those of common
shareholders. The options to purchase additional Series D Stock have an
exercise price of $.01 per share, a term of 10 years and fully vest 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 a
Qualified Public Offering, as defined in the acquisition agreement.

   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 anytime after a
Qualified Transaction and before maturity at an exercise price of $.01.

   The Company also issued 47,406 warrants to purchase 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 expiration in
May 2004.

   As discussed in note 1, the Company was taxed as an S-Corporation during
1998. As such, income taxes were the responsibility of the shareholders and
were not accounted for in the accompanying 1998 financial statements. Income
tax expense differed from the amounts computed by applying the U.S. federal
income tax rate of 34% to loss before income taxes in 1999 as a result of the

            NOTES TO CONSOLIDATED 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 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.

   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 approximately 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.

(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 March 2000, the Company entered into an agreement to merge 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 agreement, all issued
and outstanding common and preferred shares and warrants to purchase shares of
the Company will be exchanged for 8.0 million series F redeemable convertible
preferred shares of iBEAM which are convertible into common stock of iBEAM on
a share for share basis. In addition, holders of the Company's securities may
receive approximately an additional 1.1 million shares of 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 will be converted
into options to purchase shares of iBEAMs series F redeemable convertible
preferred stock. The transaction is expected to be completed in April 2000.

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.

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.

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

<PAGE>

outstanding share of Common Stock was divided into three shares of Common
Stock. The total number of shares that this corporation is authorized to issue
is One Hundred and Forty Million (140,000,000) shares. One Hundred and Twenty
Million (120,000,000) shares shall be Common Stock and Twenty Million
(20,000,000) 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 One Million Three Hundred and Fifty Thousand
(1,350,000) shares. The second series of Preferred Stock shall be designated
"Series B Preferred Stock," consisting of Three Million Three Hundred and
Eighty Thousand (3,380,000) shares. The third series of Preferred Stock shall

          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 and Series E 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 or Series E 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 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.
              -------------------

          (a)  Subject to the rights of any series of Preferred Stock that may
from time to time come into existence, the holders of shares of Series A,
Series B, Series C, Series D and Series E Preferred Stock shall be entitled to
receive dividends, out of any assets legally available therefor, prior and in
preference to any declaration or payment of any dividend (payable other than
in Common Stock or other securities and rights convertible into or entitling
the holder thereof to receive, directly or indirectly, additional shares of
Common Stock of this corporation) on the Common Stock of this corporation, at
the rate of (A) $0.096 per share per annum for each

                                       2
<PAGE>

share of Series A Preferred Stock then held by them (as adjusted for any stock
splits, stock dividends, recapitalizations or the like), (B) $0.132 per share
per annum for each share of Series B Preferred Stock then held by them (as
adjusted for any stock splits, stock dividends, recapitalizations or the
like), (C) $0.274 per share per annum for each share of Series C Preferred
Stock then held by them (as adjusted for any stock splits, stock dividends,
recapitalizations or the like), (D) $0.477 per share per annum for each share
of Series D Preferred Stock then held by them (as adjusted for any stock
splits, stock dividends, recapitalizations or the like), (E) $1.10 per share
per annum for each share of Series E Preferred Stock then held by them or such
greater amount as is paid on the Common Stock, payable when, as, and if
declared by the Board of Directors. Such dividends shall not be cumulative.
The holders of the outstanding Series A, Series B, Series C, Series D or
Series E Preferred Stock can waive any dividend preference that such holders
of each such 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 or Series E Preferred
Stock respectively, then outstanding.

          2.  Liquidation Preference.
              ----------------------

          (a)  In the event of any liquidation, dissolution or winding up of
this corporation, either voluntary or involuntary, subject to the rights of
series of Preferred Stock that may from time to time come into existence, the
holders of Series A, Series B, Series C, Series D and Series E Preferred Stock
shall be entitled to receive, prior and in preference to any distribution of
any of the assets of this corporation to the holders of Common Stock by reason
of their ownership thereof, an amount per share equal to the sum of (A) $1.20
for each outstanding share of Series A Preferred Stock (the "Original Series A
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); (B) $1.65 for each outstanding
share of Series B Preferred Stock (the "Original Series B 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); (C) $3.42 for each outstanding share of Series
C Preferred Stock (the "Original Series C 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); (D) $5.96 for each outstanding share of Series D Preferred Stock
(the "Original Series D 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) and (E)
$13.75 for each outstanding share of Series E Preferred Stock (the "Original
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). 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 and Series E 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 and Series E Preferred Stock in proportion to the foregoing
respective liquidation preferences of such holder.

                                       3
<PAGE>

          (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 and Series E 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 and Series E
Preferred Stock) until the value of the assets distributed to or the
consideration received by such holders in the aggregate equals $180,000,000
(including amounts paid pursuant to subsection (a) of this Section 2);

          (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 and Series E 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

                                       4
<PAGE>

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

                     (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 and Series E 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(e)(iv) hereof.

               (iv)  This corporation shall give each holder of record of
Series A, Series B, Series C, Series D or Series E 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 and Series E 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 and Series E 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,

                                       5
<PAGE>

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. The initial Conversion Price per share for shares of Series A,
Series B, Series C, Series D and Series E 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 and Original Series E Issue Price
respectively; provided, however, that the Conversion Price for the Series A,
Series B, Series C, Series D and Series E Preferred Stock shall be subject to
adjustment from time to time as set forth in subsection 3(d). On and after
January 20, 2000, the Conversion Price shall be equal to (A) $0.40 for each
outstanding share of Series A Preferred Stock; (B) $0.55 for each outstanding
share of Series B Preferred Stock; (C) $1.14 for each outstanding share of
Series C Preferred Stock; (D) $1.9867 for each outstanding share of Series D
Preferred Stock (subject to further adjustment from time to time as set forth
in subsection 3(d)).

          (b)  Automatic Conversion.  Each share of Series A, Series B, Series
               --------------------
C and Series E 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 or Series E 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 $3.97 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 and Series E 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 or Series E
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 or Series E 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 or Series E 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
or Series E Preferred Stock to be converted, and the person or persons
entitled to receive the shares of Common Stock issuable upon such conversion
shall be treated for all purposes as the record holder or holders of such
shares of Common Stock 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 or Series E 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 or Series E Preferred Stock shall not be deemed to have
converted such Series A,

                                       6
<PAGE>

Series B, Series C, Series D or Series E 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 and Series E 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 or Series E
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.

                     (B)  No adjustment of the Conversion Price for the Series
A, Series B, Series C, Series D or Series E 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.

                     (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,

                                       7
<PAGE>

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 and the Series E Preferred Stock, to the extent in any way
affected by or computed using such 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

exchangeable securities, the Conversion Price of the Series A, Series B,

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

                                       8

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

                     (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

<PAGE>

fixed dollar amounts for any stock splits, stock dividends, combinations,

connection with the conversion of such preferred stock;

                     (H)  the issuance of a warrant to America Online to

               (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 or Series E 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,

E 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.

          (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 and Series E 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
and/or Series E 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 and Series E Preferred Stock shall
thereafter be entitled to receive upon conversion of the Series A, Series B,
Series C, Series D or Series E Preferred Stock, the number of shares of stock
or other securities or property

                                       10
<PAGE>

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 and Series E 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 and
Series E 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
               -------------
Certificate of Incorporation or through any reorganization, recapitalization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by this corporation, but will at all times in good faith assist in
the carrying out of all the provisions of this Section 3 and in the taking of
all such action as may be necessary or appropriate in order to protect the
Conversion Rights of the holders of the Series A, Series B, Series C, Series D
and Series E Preferred Stock against impairment.

          (h)  No Fractional Shares and Certificate as to Adjustments.
               ------------------------------------------------------

               (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 or Series E
Preferred Stock and the number of shares of Common Stock to be issued shall be
rounded to the nearest whole share. Whether or not fractional shares are
issuable upon such conversion shall be determined on the basis of the total
number of shares of Series A, Series B, Series C, Series D and/or Series E
Preferred Stock the holder is at the time converting into Common Stock and the
number of shares of Common Stock issuable upon such aggregate conversion.

               (ii)  Upon the occurrence of each adjustment or readjustment of
the Conversion Price of Series A, Series B, Series C, Series D or Series E
Preferred Stock pursuant to this Section 3, this corporation, at its expense,
shall promptly compute such adjustment or readjustment in accordance with the
terms hereof and prepare and furnish to each holder of Series A, Series B,
Series C, Series D and Series E Preferred Stock a certificate setting forth
such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based. This corporation shall, upon the
written request at any time of any holder of Series A, Series B, Series C,
Series D or Series E 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 or Series E Preferred Stock.

          (i)  Notices of Record Date.  In the event of any taking by this
               ----------------------
corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, any right to
subscribe for, purchase or otherwise acquire any shares of stock of any class
or any other securities or property, or to receive any other right, this
corporation shall mail to each holder of

                                       11
<PAGE>

Series A, Series B, Series C, Series D and Series E Preferred Stock, at least
twenty (20) days prior to the date specified therein, a notice specifying the
date on which any such record is to be taken for the purpose of such dividend,
distribution or right, and the amount and character of such dividend,
distribution or right.

               ---------------------------------------------
shall at all times reserve and keep available out of its authorized but
unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series A, Series B, Series C, Series D and
Series E Preferred Stock, such number of its shares of Common Stock as shall
from time to time be sufficient to effect the conversion of all outstanding
shares of the Series A, Series B, Series C, Series D and Series E 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 and Series E
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 to be given to the holders of shares of Series A, Series B, Series C, Series
D and/or Series E Preferred Stock shall be deemed given if deposited in the
United States mail, postage prepaid, and addressed to each holder of record at

to any question upon which holders of Common Stock have the right to vote.
Fractional votes shall not, however, be permitted and any fractional voting
rights available on an as-converted basis (after aggregating all shares into

Preferred Stock held by each holder could be converted) shall be rounded to
the nearest whole number (with one-half being rounded upward).

          (b)  Voting for the Election of Directors.

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

follows:

                     (f) The term "register," "registered," and "registration"

exchange for, or in replacement of, the shares referenced in (i) through (vi)
above, excluding in all cases, however, any Registrable Securities sold by a
person in a transaction in which his rights under this Section 1 are not
assigned.

                     (h) The number of shares of Registrable Securities
outstanding shall be determined by the number of shares of Common Stock
outstanding that are, and the number of shares of Common Stock issuable pursuant
to then exercisable or convertible securities that are, Registrable Securities.

                     (i) The term "SEC" shall mean the Securities and Exchange
Commission.

                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 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

                                      -2-
<PAGE>

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

                         (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

                                      -3-
<PAGE>

                         (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.

                     (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

                                      -4-
<PAGE>

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 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

                                      -5-
<PAGE>

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;

                     (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

                                      -6-
<PAGE>

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 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

                                      -7-
<PAGE>

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 l.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 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.

                                      -8-
<PAGE>

                     (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.

                     (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

                                      -9-
<PAGE>

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,

                                      -10-
<PAGE>

holds at least 300,000 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 "Market Stand-Off" Agreement.  Each Holder hereby agrees
                      ---------------------------
that it will not, without the prior written consent of the managing underwriter,
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, 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

                                      -11-
<PAGE>

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 1,800,000 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 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.

                                      -12-
<PAGE>

                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 2.10, 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 900,000 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.

                     (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

                                      -13-
<PAGE>

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 $3.97 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 $3.97 per
share

                                      -14-
<PAGE>

(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
disclosure of trade secrets to such representative or if such Investor or its
representative is a direct competitor of the Company. The covenants set forth in
this Section 2.6 shall terminate and be of no further force or effect upon the
occurrence of either event specified in Section 2.3 hereof.

                2.7  Intel Observer Rights.  As long as Intel Corporation
                     ---------------------
("Intel"), together with its subsidiaries (defined as entities which Intel
beneficially owns, either directly or indirectly, at least 50% of the voting
securities) in the aggregate own not less than 50% of the shares of the Series C
Preferred Stock Intel purchased pursuant to the Series C Agreement (or an
equivalent amount of Common Stock issued upon conversion thereof), the Company
shall invite a representative of Intel (the "Intel Observer") 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 the Company reserves the right to withhold any information and to
exclude the Intel Observer from any meeting or portion thereof if access to such
information or attendance at such meeting could (a) adversely affect the
attorney-client privilege between the Company and its counsel; or (b) result in
disclosure of confidential or proprietary information of third parties. In
addition, a majority of the Company's nonemployee directors shall have the right
to exclude the Intel Observer from portions or entire meetings of the Board of
Directors or omit to provide the Intel Observer with certain information or
analysis which would pose a conflict of interest for Intel. Any disclosures of
confidential information between the Company and the Intel Observer and Intel
will be governed by the terms of the Corporate Non Disclosure Agreement Number
122651 dated August 19, 1998 and any related Confidential Information
Transmittal records executed between the Company and Intel. The Company
acknowledges that Intel will likely have, from time to time, information that
may be of interest to the Company ("Information") regarding a wide variety of
matters including, by way of example only, (1) Intel's technologies, plans and
services, and plans and strategies relating thereto, (2) current and future
investments Intel has made, may make, may consider or may become aware of with
respect to other companies and other technologies, products and services,
including, without limitation, technologies, products and services that may be
competitive with the Company's, and

                                      -15-
<PAGE>

(3) developments with respect to the technologies, products and services, and
plans and strategies relating thereto, of other companies, including, without
limitation, companies that may be competitive with the Company. The Company
recognizes that a portion of such Information may be of interest to the Company.
Such Information may or may not be known by the Intel Observer. The Company
agrees that Intel and the Intel Observer shall have no duty to disclose any
Information to the Company or permit the Company to participate in any projects
or investments based on any Information, or to otherwise take advantage of any
opportunity that may be of interest to the Company if it were aware of such
Information, and hereby waives, to the extent permitted by law, any claim based
on the corporate opportunity doctrine or otherwise that could limit Intel's

evidencing the shares of Common Stock and Preferred Stock to bear the legend
required by Section 6 herein and/or failure of the Company to supply, free of
charge, a copy of this Agreement as provided under this Section 6 shall not
affect the validity or enforcement of this Agreement.

consent of the holders of a majority of the shares held by the Parties hereto,

instance and either retroactively or prospectively) only with the written
consent of the holders of a majority of the then outstanding voting securities
held by the Party or Parties for whose benefit such term has been included in
this Agreement. Any amendment or waiver so effected shall be binding upon the
Parties hereto.

          17. Stock Splits, Stock Dividends, etc. In the event of any issuance
              ----------------------------------

Agreement.

          19. Binding Effect.  In addition to any restriction on transfer that

this Agreement shall be binding upon the Parties, their respective heirs,
successors and assigns and to such additional individuals or entities that may
become stockholders of the Company and that desire to become Parties hereto;
provided that for any such transfer to be deemed effective, the transferee shall

attached hereto as Exhibit A. Upon the execution and delivery of an Adoption
Agreement by any transferee reasonably acceptable to the Company, such
transferee shall be deemed to be a Party hereto as if such transferee's
signature appeared on the signature pages hereto. By their execution hereof or
any Adoption Agreement, each of the Parties hereto appoints the Company as its
attorney-in-fact for the purpose of executing any Adoption Agreement which may
be required to be delivered hereunder.

conflicts of law principles thereof.

              ----------------
agreement of the Parties as it relates to this subject matter and does hereby
supersede all other agreements of the Parties relating to the subject matter
hereof.

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

                                       6
<PAGE>

          23. Arbitration.  Any controversy between the Parties hereto involving
              -----------
any claim arising out of or relating to the termination of this Agreement, will
be submitted to and be settled by final and binding arbitration in Santa Clara,
California, in accordance with the then current Commercial Arbitration Rules of
the American Arbitration Association (the "AAA"), and judgment upon the award
rendered by the arbitrators may be entered in any court having jurisdiction
thereof. Such arbitration shall be conducted by three (3) arbitrators chosen by

hearing as follows: (a) exchange of witness lists and copies of documentary
evidence and documents relating to or arising out of the issues to be

reporter shall record all hearings, with such record constituting the official
transcript of such proceedings.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR INVESTMENT
AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AS AMENDED.  THESE
SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE
ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE SECURITIES UNDER SAID
ACT OR LAWS OR AN OPINION OF COUNSEL SATISFACTORY TO THE CORPORATION THAT SUCH
REGISTRATION IS NOT REQUIRED.

                         iBEAM BROADCASTING CORPORATION

                           STOCK SUBSCRIPTION WARRANT

                                                               February 25, 2000

      1.  General.
          -------
          (a)  THIS CERTIFIES that, for value received, AMERICA ONLINE, INC.
("AOL") is entitled to subscribe for and purchase from iBEAM BROADCASTING
CORPORATION, a Delaware corporation (the "Corporation"), at any time or from
time to time during the period (the "Exercise Period") commencing on the date of
a Stipulated Event and ending on the fourth anniversary of the date hereof, on
the terms and subject to the provisions hereinafter set forth, a number of
shares (subject to adjustment as provided herein) (the "Warrant Shares") of
fully paid and non-assessable shares of Common Stock, $.0001 par value, of the
Corporation determined by dividing $5,000,000 by the Exercise Price.

This Warrant is being issued pursuant to a System Services Agreement dated as of
January 27, 2000 (the "Agreement"), between the Corporation and AOL.  All terms
used but not defined herein shall have the meanings set forth in the Agreement.

          (b)  This Warrant shall become exercisable as to all of the Warrant
Shares immediately upon the occurrence of a Stipulated Event. As used herein,
the term "Stipulated Event" shall mean the earlier of (a) a Corporate
Transaction (as hereinafter defined) or (b) three years from the date hereof or
(c) a termination of the Agreement, except for a termination by the Corporation
for material breach by AOL. "Corporate Transaction" means (A) any consolidation
or merger of the Corporation with or into any other corporation or other entity,
other than any merger or consolidation resulting in the holders of the capital
stock of the Corporation entitled to vote for the election of directors
immediately prior to the transaction holding a majority of the capital stock of
the surviving or resulting corporation or other entity entitled to vote for the
election of directors, (B) any person or entity (including any affiliates
thereof) becoming the holder of a majority of the capital stock of the
Corporation entitled to vote for the election of directors, (C) any sale or
other disposition by the Corporation of all or substantially all of its assets
or capital stock or (D) a public offering (the "IPO") for the account of the
Corporation of shares of capital stock of the Corporation pursuant to a
registration statement filed under the Securities Act of 1933, as amended (the
"Securities Act") with gross proceeds of at least $20,000,000.
<PAGE>

          (c)  The Exercise Price shall be (x) the price per share of the
Corporation's Common Stock to the public in the IPO ( less per share underwriter
commissions and discounts), or (y) if a Corporate Transaction other than an IPO
occurs, or a Corporate Transaction does not occur by February 25, 2003, shall be
$13.75 per share subject to adjustment as provided in Section 4.

     2.  Exercise of Warrant.  The rights represented by this Warrant may be
         -------------------
exercised by the holder hereof, as to those Warrant Shares for which this
Warrant is then exercisable as determined in accordance with Section 1, in whole
or in part, at any time or from time to time during the Exercise Period, by the
surrender of this Warrant (properly endorsed) at the office of the Corporation
at 645 Almanor Avenue, Suite 100 Sunnyvale, CA 94086, or at such other agency or
office of the Corporation in the United States of America (the "Designated
Office") as it may designate by notice in writing to the holder hereof at the
address of such holder appearing on the books of the Corporation, and by payment
(either in cash, by check, by cancellation of indebtedness and/or in shares of
capital stock of the Corporation valued at Fair Market Value (as hereinafter
defined) on the date of such exercise) to the Corporation of the Warrant Price
for each Warrant Share being purchased.  In the event of the exercise of the
rights represented by this Warrant, a certificate or certificates for the
Warrant Shares so purchased, registered in the name of the holder, and if this
Warrant shall not have been exercised for all of the Warrant Shares, a new
Warrant, registered in the name of the holder hereof, of like tenor to this
Warrant, shall be delivered to the holder hereof within a reasonable time, not
exceeding ten days, after the rights represented by this Warrant shall have been
so exercised.  The person in whose name any certificate for Warrant Shares is
issued upon exercise of this Warrant shall for all purposes be deemed to have
become the holder of record of such shares on the date on which the Warrant was
surrendered and payment of the Warrant Price and any applicable taxes was made,
irrespective of the date of delivery of such certificate, except that, if the
date of such surrender and payment is a date when the stock transfer books of
the Corporation are closed, such person shall be deemed to have become the
holder of such shares at the close of business on the next succeeding date on
which the stock transfer books are open.

     3.   Exchange of Warrant.
          -------------------
          (a)  In addition to, and independent of, the rights of the holder of
this Warrant set forth in Section 2 hereof, the holder hereof may at any time or
from time to time after a Stipulated Event elect to receive, without the payment
by the holder of any additional consideration, that number of Warrant Shares
determined as hereinafter provided in this Section 3 by the surrender of this
Warrant or any portion hereof to the Corporation, accompanied by an executed
Notice of Exchange in substantially the form thereof attached hereto (the "Net
Issue Election"). Thereupon, the Corporation shall issue to the holder hereof
such number of fully paid and nonassessable Warrant Shares as is computed using
the following formula:

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

where X =  the number of Warrant Shares to be issued to the holder pursuant to
this Section 3.

                                       2
<PAGE>

     Y =  the number of Warrant Shares covered by this Warrant in respect of
          which the Net Issue Election is made pursuant to this Section 3.

     A =  the Fair Market Value (as hereinafter defined) of one Warrant Share
          determined at the time the Net Issue Election is made pursuant to this
          Section 3 (the "Determination Date").

     B =  the Warrant Price in effect under this Warrant at the time the Net
          Issue Election is made pursuant to this Section 3.

For purposes of the above calculation, "Fair Market Value" of one Warrant Share
as of the Determination Date shall mean:

                (i)    (A) if the Common Stock of the Corporation is not then
     traded on a national securities exchange, the average of the closing prices
     quoted on the National Association of Securities Dealers, Inc. Automated
     Quotation National Market System, if applicable, or the average of the last
     bid and asked prices of the Common Stock quoted in the over-the-counter-
     market or (B) if the Common Stock is then traded on a national securities
     exchange, the average of the high and low prices of the Common Stock listed
     on the principal national securities exchange on which the Common Stock is
     so traded, in each case for the twenty (20) trading days immediately
     preceding the Determination Date or, if such date is not a business day on
     which shares are traded, the next immediately preceding trading day;

                (ii)   in the event of a Warrant Exchange in connection with a
     Corporate Transaction, the value per share of Common Stock received or
     receivable by each holder thereof (assuming for purposes of this
     determination, in the case of a sale of assets, the Corporation is
     liquidated immediately following such sale and the consideration paid to
     the Corporation is immediately distributed to its stockholders); and

                (iii)  in all other circumstances, the fair market value per
share of Common Stock as determined by a nationally recognized independent
investment banking firm jointly selected by the Corporation and the holder of
this Warrant or, if such selection cannot be made within five business days
after delivery of the Notice of Exchange referred to above, by a nationally
recognized independent investment banking firm selected by the American
Arbitration Association then obtaining.

The closing of any Warrant Exchange shall take place at the offices of the
Corporation on the date specified in the Notice of Exchange (the "Exchange
Date"), which shall be not less than five and not more than 30 days after the
delivery of such Notice.  At such closing, the Corporation shall issue and
deliver to the holder or its designee a certificate or certificates for the
Warrant Shares to be issued upon such Warrant Exchange, registered in the name
of the holder or such designee, and if such Warrant Exchange shall not have been
for all Warrant Shares, a new Warrant, registered in the name of the holder, of
like tenor to this Warrant for the number of shares still subject to this
Warrant following such Warrant Exchange.

<PAGE>

     4.   Adjustment of Warrant Price.
          ---------------------------

          (a)  The Warrant Price shall be subject to adjustment from time to
time as follows:

               (i)     If, at any time during the Exercise Period, the number of
     shares of Common Stock outstanding is increased by a stock dividend payable
     in shares of Common Stock or by a subdivision or split-up of shares of
     Common Stock, then, following the record date fixed for the determination
     of holders of Common Stock entitled to receive such stock dividend,
     subdivision or split-up, the Warrant Price shall be appropriately decreased
     and the number of shares of Common Stock issuable upon exercise of this
     Warrant shall be appropriately increased, in each case in proportion to
     such increase in outstanding shares.

               (ii)    If, at any time during the Exercise Period, the number of
     shares of Common Stock outstanding is decreased by a combination of the
     outstanding shares of Common Stock, then, following the record date for
     such combination, the Warrant Price shall be appropriately increased and
     the number of shares of Common Stock issuable upon exercise of this Warrant
     shall be appropriately decreased, in each case, in proportion to such
     decrease in outstanding shares.

               (iii)  Whenever the Warrant Price shall be adjusted as provided
in this Section 4 the Corporation shall forthwith file, at the office of the
Corporation or any transfer agent designated by the Corporation for the Common
Stock, a statement, signed by its chief financial officer, showing in detail the
facts requiring such adjustment and the adjusted Warrant Price. The Corporation
shall also cause a copy of such statement to be sent by first-class certified
mail, return receipt requested, postage prepaid, to each holder of a Warrant at
his or its address appearing on the Corporation's records. Where appropriate,
such copy may be given in advance and may be included as part of a notice
required to be mailed under the provisions set forth immediately below.

          (b)  In the event the Corporation shall take any action of the types
described in Section 4 or Section 12, the Corporation shall give notice to each
holder of a Warrant in the manner set forth herein, which notice shall specify
the record date, if any, with respect to any such action and the date on which
such action is to take place. Such notice shall also set forth such facts with
respect thereto as shall be reasonably necessary to indicate the effect of such
action (to the extent such effect may be known at the date of such notice) on
the Warrant Price then in effect and the number, kind or class of shares or
other securities or property which shall be delivered or purchasable upon the
occurrence of such action or deliverable upon exercise of this Warrant. In the
case of any action which would require the fixing of a record date, the
Corporation shall use reasonable efforts to provide such notice at least 20 days
prior to the date so fixed, and in case of all other action, the Corporation
shall use reasonable efforts to provide such notice at least 30 days prior to
the taking of such proposed action. Failure to give such notice, or any defect
therein, shall not affect the legality or validity of any such action.

     5.  Adjustment of Warrant Shares. Upon each adjustment of the Warrant Price
         ----------------------------
as provided in Section 4, the holder hereof shall thereafter be entitled to
subscribe for and purchase,

                                       4
<PAGE>

at the Warrant Price resulting from such adjustment, the number of Warrant
Shares equal to the product of (i) the number of Warrant Shares existing prior
to such adjustment and (ii) the quotient obtained by dividing (A) the Warrant
Price existing prior to such adjustment by (B) the new Warrant Price resulting
from such adjustment. No fractional shares of Common Stock shall be issued as a
result of any such adjustment, and any fractional shares resulting from the
computations pursuant to this paragraph shall be eliminated without
consideration.

     6.  Covenants as to Common Stock.  The Corporation covenants and agrees
         ----------------------------
that all shares of Common Stock that may be issued upon the exercise of the
rights represented by this Warrant, will, upon issuance, be validly issued,
fully paid and non-assessable and free from all taxes, liens and charges with
respect to the issuance thereof. The Corporation further covenants and agrees
that the Corporation will from time to time take all such action as may be
requisite to assure that the stated or par value per share of Common Stock is at
all times equal to or less than the then effective Warrant Price per share of
Common Stock issuable upon exercise of this Warrant. The Corporation further
covenants and agrees that the Corporation will at all times have authorized and
reserved, free from preemptive rights, a sufficient number of shares of Common
Stock to provide for the exercise of the rights represented by this Warrant. If
and so long as the Common Stock issuable upon the exercise of the rights
represented by this Warrant is listed on any national securities exchange, the
Corporation will, if permitted by the rules of such exchange, list and keep
listed on such exchange, upon official notice of issuance, all shares of such
capital stock.

     7.  No Shareholder Rights.  This Warrant shall not entitle the holder
         ---------------------
hereof to any voting rights or other rights as a shareholder of the Corporation.

     8.  Restrictions on Transfer of the Warrant Shares.
         ----------------------------------------------

         (a)  The holder of this Warrant acknowledges that neither this Warrant
nor the Warrant Shares have been registered under the Securities Act and the
holder of this Warrant agrees that no sale, transfer, assignment, hypothecation
or other disposition of the Warrant Shares shall be made (except for transfers
to any entity controlled by or under common control with AOL, as evidenced by
ownership of 50% or more of the outstanding voting stock of such entity) in the
absence of (i) current registration statement under the Securities Act as to the
Warrant Shares and the registration or qualification of the Warrant Shares under
any applicable state securities laws is then in effect or (ii) an opinion of
counsel reasonably satisfactory to the Corporation to the effect that such
registration or qualification is not required. The Warrant Shares shall also be
subject to the restrictions on transfer set forth in the Amended and Restated
Investors' Rights Agreement dated as of February __, 2000 (the "Rights
Agreement") by and among the Corporation and the investors listed on Schedule A
thereto, as such agreement may be heretofore amended.

         (b)  It is understood that the certificates evidencing the Warrant
Shares may bear one or all of the following legends:

              (i)   "These securities have not been registered under the
     Securities Act of 1933, as amended. They may not be sold, offered for sale,
     pledged or hypothecated in the absence of a registration statement in
     effect with respect to the securities under such

                                       5
<PAGE>

     Act or an opinion of counsel satisfactory to the Company that such
     registration is not required or unless sold pursuant to Rule 144 of such
     Act."

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

              (iii) "These securities are subject to a market-standoff of 180
     days in connection with the Company's initial public offering."

     9.  Restrictions on Transfer of the Warrant.
         ---------------------------------------

         (a)  Except as expressly permitted in the following sentence, this
Warrant and the rights hereunder are not transferable by the holder hereof.
Notwithstanding the foregoing, this Warrant may be assigned to any entity
controlled by or under common control with (as evidenced by ownership of 50% or
more of the outstanding voting stock of such entity) AOL. Subject to compliance
with the restrictions on transfer set forth in this Section 9, each transfer of
this Warrant and all rights hereunder, in whole or in part, shall be registered
on the books of the Corporation to be maintained for such purpose, upon
surrender of this Warrant at the Designated Office, together with a written
assignment of this Warrant in the form attached hereto duly executed by the
holder or its agent or attorney. Upon such surrender and delivery, the
Corporation shall execute and deliver a new Warrant or Warrants in the name of
the assignee or assignees and in the denominations specified in such instrument
of assignment, and shall issue to the assignor a new Warrant evidencing the
portion of this Warrant not so assigned, if any. All Warrants issued upon any
assignment of Warrants shall be the valid obligations of the Corporation,
evidencing the same rights, and entitled to the same benefits as the Warrants
surrendered upon such registration of transfer or exchange.

     (b)  It is understood that each Warrant shall be stamped or otherwise
imprinted with a legend in substantially the following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
     INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AS
     AMENDED.  THESE SECURITIES MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
     HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO
     THE SECURITIES UNDER SAID ACT OR LAWS OR AN OPINION OF COUNSEL SATISFACTORY
     TO THE CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED.

     10.  Market Stand-Off Agreement.  The holder hereof hereby agrees that it
will not, without the prior written consent of the managing underwriter, during
the period commencing on the date of the final prospectus relating to the
Corporation's initial public offering and ending on the date specified by the
Corporation 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

                                       6
<PAGE>

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
hereof 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 Corporation's initial public offering are intended third
party beneficiaries of this Section 10 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 Corporation may impose stop-
transfer instructions with respect to the Warrant Shares until the end of such
period

     11.  Registration Rights.  The holder shall have the registration rights
          -------------------
set forth in the Rights Agreement with respect to the Warrant Shares.

     12.  Reorganizations, Etc.  In case, at any time during the Exercise
          --------------------
Period, of any capital reorganization, of any reclassification of the stock of
the Corporation (other than a change in par value or from par value to no par
value or from no par value to par value or as a result of a stock dividend or
subdivision, split-up or combination of shares), or the consolidation or merger
of the Corporation with or into another corporation (other than a consolidation
or merger in which the Corporation is the continuing operation and which does
not result in any change in the Common Stock) or of the sale of all or
substantially all the properties and assets of the Corporation as an entirety to
any other corporation, this Warrant shall, after such reorganization,
reclassification, consolidation, merger or sale, be exercisable for the kind and
number of shares of stock or other securities or property of the Corporation or
of the corporation resulting from such consolidation or surviving such merger or
to which such properties and assets shall have been sold to which such holder
would have been entitled if he had held the Common Stock issuable upon the
exercise hereof immediately prior to such reorganization, reclassification,
consolidation, merger or sale. In any such reorganization or other action or
transaction described above, appropriate provision shall be made with respect to
the rights and interests of the holder of this Warrant to the end that the
provisions hereof (including, without limitation, provisions for adjustments of
the Warrant Price and of the number of shares purchasable and receivable upon
the exercise of this Warrant) shall thereafter be applicable, as nearly as may
be, in relation to any shares of stock, securities or assets thereafter
deliverable upon the exercise hereof. The Corporation will not effect any such
consolidation, merger or sale unless, prior to the consummation thereof, the
successor corporation or entity (if other than the Corporation) resulting from
such transaction or the corporation or entity purchasing such assets shall
assume by written instrument, executed and mailed or delivered to the registered
holder hereof at the last address of such holder appearing on the books of the
Corporation, the obligation to deliver to such holder such shares of stock,
securities or assets as, in accordance with the foregoing provisions, such
holder may be entitled to purchase.

     13.  Lost, Stolen, Mutilated or Destroyed Warrant.  If this Warrant is
          --------------------------------------------
lost, stolen, mutilated or destroyed, the Corporation may, on such terms as to
indemnity or otherwise as it may in its discretion impose (which shall, in the
case of a mutilated Warrant, include the surrender thereof), issue a new Warrant
of like denomination and tenor as the Warrant so lost, stolen, mutilated or
destroyed. Any such new Warrant shall constitute an original contractual

obligation of the Corporation, whether or not the allegedly lost, stolen,

changed, waived, discharged or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

                           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 [*] Dollars (US$[*]), as follows: (i) [*]
Dollars (US$[*]) upon execution of this Agreement and (ii) [*] Dollars (US$[*])
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:

               Quarter    Revenue Sharing Threshold
               -------    -------------------------

               1st        $[*]

                                       2

[*] Certain information on this page has been omitted and filed separately

<PAGE>

               2nd        $[*]

               3rd        $[*]

               4th        $[*]

               5th        $[*]

               6th        $[*]

               7th        $[*]

               8th        $[*]


     (ii)    There shall be no carryover of the Revenue Sharing Threshold from
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

                                       3

[*] Certain information on this page has been omitted and filed separately

<PAGE>

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 [*] of iBEAM common stock at ______
dollars per share (price to be determined after execution of the agreement
concurrent with execution of a warrant agreement between AOL and iBEAM.
(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 an offering of iBEAM common stock to the public per
registration with the SEC for an aggregate value of greater the [*]. 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

                                       4

<PAGE>

     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

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
with the Commission. Confidential treatment has been requested with respect to

<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

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 [*] Dollars (US$[*]) in Gross Revenues
owed to AOL (pursuant to Section 2(b) of this Agreement) by the first
anniversary of the Effective Date ("Insufficient Gross Revenues Termination");
provided, however, that upon any such Insufficient Gross Revenues Termination,
- --------  -------
AOL shall refund to iBEAM [*] Dollars (US$[*]).


     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

under this Agreement and AOL's purchase of Services and will permit examination
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.

     17. Notices.  All notices or reports permitted or required under this
         -------
Agreement shall be in writing and shall be delivered by personal delivery,
nationally recognized overnight courier, telegram, or facsimile transmission or
by registered mail, return receipt requested.  Notices shall be sent to the
signatories of this Agreement at the address set forth above or such other
address as either party may specify in writing.  Notices shall be effective upon
receipt. In the case of AOL, such notice will be provided to both the President,
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
         ----------

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.

         --------
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.

1.  iBEAM will be responsible for the following actions:
    .  A satellite pre-installation site survey of the facility by phone or at
       iBEAM's and NorthPoint's option at customer site.

    .  The installation of the satellite dish utilizing a non-penetrating roof
       mount on the roof of the facility or a designated area of the building,
       depending on the availability of such space.

    .  The running of coaxial cable to the data or rack room where the iBEAM
       MaxCaster indoor components will be racked.

    .  The racking and cabling of the server and switch components of the
       MaxCaster.

    .  Registration and pointing of the satellite system.

       remote monitoring process.

    .  Alert NorthPoint during power outage or any iBEAM Network outage, whether
       planned or otherwise, by telephoning NorthPoint at NorthPoint-specified
       numbers.

2.  The Member will be responsible for the following actions:

    .  Completion of the customer data network site survey. This information is
       critical to the iBEAM Tier 1 NOC in the monitoring of the MaxCaster and
       to the integration of the MaxCaster in the data network. The customer
       will be required to provide IP addresses, host ID names, subnet masks,
       and gateway default as specified by iBEAM.

    .  Designate a single point of contact for satellite and network
       installation issues.

    .  Allow iBEAM NOC to monitor traffic to the switch, server or other
       equipment for the following protocols, SNMP, FTP, Telnet, Ping,

                  Exhibit D to Agreement No. 093099NPoint

                               Portal Description

     Hosting:  iBEAM will host the co-branded portal page at no cost to Member.
     The portal will display links to live and on demand streams that are
     available on the iBEAM Network. iBEAM undertakes to use commercially
     reasonable efforts to acquire the license to use Content Provider name and
     Content on the portal page.  The portal will be accessible to all Internet
     users.

     Portal Branding and Creation:  iBEAM and Member will equally divide the
     cost of developing and maintaining the co-branded portal.  iBEAM will
     provide any project management and operational support necessary to roll-
     out and sustain the portal project.  iBEAM and Member will jointly agree on
     the design, content and operation of the portal.  iBEAM will develop a
     proof-of-concept portal at no cost to Member.  iBEAM and Member will
     jointly generate and fund the advertising associated with the portal.  The
     objective of this advertising is to drive demand for Member DSL service and
     iBEAM-delivered streaming media.

     DSL Promotion:  The sub-portal will contain static links to the streaming
     content of iBEAM content providers who have chosen to utilize the portal.
     When a Member user clicks on a link, they will see an interstitial message
     that informs them they are viewing an iBEAM enabled stream that is
     available to them because they are a Broadband user.  If a non-Member user
     clicks on a link, they will receive an interstitial message encouraging
     them to sign up for NorthPoint DSL service to get the high-fidelity version
     of the stream.

     Portal Promotion:  iBEAM will promote the Member sub-portal with all iBEAM
     content partners, as well as with iBEAM technology partners and joint
     iBEAM/Member ISP customers.  Also, iBEAM will include the Member sub-portal
     whenever reasonable in iBEAM end user marketing and promotion efforts.

Mr. Jeremy Zullo
iBEAM Broadcasting

          Re: Offer of Employment
              -------------------

Dear Jeremy:

          I am writing to confirm our offer of the following terms of your
employment commencing July 1, 1999 and continuing thereafter as provided herein:

          If you accept this offer, your title will be Executive Director
Development, reporting to Vice President Engineering. Your monthly base salary
will be $12,916.67 ($155,000 annually) less all applicable deductions. In
addition, you will be eligible to earn an annual bonus of up to $20,000 per
year, less all applicable deductions, based on your achievement of performance
goals set for you at the beginning of each quarter. I will set your goals within
the first 30 days of each quarter and communicate those goals to you in writing.
If you meet these goals, you will earn the aforementioned bonus.

          The Company will also award you an additional option to purchase
15,000 shares of Company common stock at the fair market value on the date of
grant. This option will become exercisable over the next four years with one-
quarter of the shares exercisable after one year and the remaining shares
becoming exercisable in equal installments over the next 36 months. This option
grant will be contingent upon you executing the Company's standard stock option
agreement, and will be subject to all terms of that agreement and the Company's
stock option plan. This grant is also contingent upon approval by the Company's
Board of Directors, which we expect to occur during the next meeting following
your acceptance of this offer.

          In exchange for this additional stock and compensation, you agree to
remain employed by the Company through June 30, 2000. Although the Company may
terminate your employment at any time for any reason, with or without cause,
during this time period by giving you written notice of such termination, you
agree that you will remain employed with the Company through that date. If your
employment with the Company continues beyond June 30, 2000, then you will resume
being an at-will employee, that is, either you or the Company can terminate your

          Re:  Offer of Employment
               -------------------

Dear Nils:

          I am writing to confirm our offer of the following terms of your
employment commencing July 1, 1999 and continuing thereafter as provided herein:

          If you accept this offer, your title will be Chief Architect,
reporting to Vice President, Engineering. Your monthly base salary will be
$12,500.00, ($150,000 annually), less all applicable deductions. In addition,
you will be eligible to earn an annual bonus of up to $30,000 per year, less all
applicable deductions, based on your achievement of performance goals set for
you at the beginning of each quarter. I will set your goals within the first 30
days of each quarter and communicate those goals to you in writing. If you meet
these goals, you will earn the aforementioned bonus.

          The Company will also award you an additional option to purchase
20,000 shares of Company common stock at the fair market value on the date of
grant. This option will become exercisable over the next four years with one-
quarter of the shares exercisable after one year and the remaining shares
becoming exercisable in equal installments over the next 36 months. This option
grant will be contingent upon you executing the Company's standard stock option
agreement, and will be subject to all terms of that agreement and the Company's
stock option plan. This grant is also contingent upon approval by the Company's
Board of Directors, which we expect to occur during the next meeting following
your acceptance of this offer.

          In exchange for this additional stock and compensation, you agree to
remain employed by the Company through June 30, 2000. Although the Company may
terminate your employment at any time for any reason, with or without cause,
during this time period by giving you written notice of such termination, you
agree that you will remain employed with the Company through that date. If your
employment with the Company continues beyond June 30, 2000, then you will resume
being an at-will employee, that is, either you or the Company can terminate your
employment at any time for any reason, with or without cause. You also agree
that the terms of the Proprietary Information and Inventions Agreement, executed
by you on April 8, 1998, will continue to be in effect except that paragraph 7
will be modified as set forth in this paragraph.

          Please indicate your acceptance of this offer by signing below.

                                 Sincerely,


                                 /s/ Peter Desnoes
