                               PROSPECTUS SUMMARY
   
  The following summary is qualified in its entirety by the more detailed
information and the Consolidated Financial Statements and notes thereto
appearing elsewhere in this Prospectus. Except as otherwise noted herein,
information in this Prospectus (i) assumes no exercise of the Underwriters'
over-allotment option, (ii) includes the April 1997 Series C Preferred Stock
financing as though it had occurred as of March 31, 1997 and (iii) assumes the

                                  THE COMPANY
   
  At Home Corporation (the "Company") is a leading provider of Internet
services over the cable television infrastructure to consumers and businesses.
The Company's primary offering, the @Home service, allows residential
subscribers to connect their personal computers via cable modems to a new high-
speed network developed and managed by the Company. This service enables
subscribers to receive the "@Home Experience," which includes Internet service
over hybrid fiber-coaxial ("HFC") cable at a peak data transmission speed over
300 times faster than typical dial-up connections, "always on" availability and
rich multimedia programming through an intuitive graphical user interface. The
technology foundation of the @Home Experience is the Company's scalable,
distributed, intelligent network architecture (the "@Network"), a "parallel
Internet" that optimizes traffic routing, improves security and consistency of
service, and facilitates end-to-end network management, enhancing the Company's
ability to address performance bottlenecks before they affect the user
experience. See "Business--@Network Architecture." The content foundation of
the @Home Experience is provided by the Company's @Media group, which
aggregates content, sells advertising to businesses and will provide premium
services to @Home subscribers. For businesses, the Company's @Work services
provide a platform for Internet, intranet and extranet connectivity solutions
and networked business applications over both cable infrastructure and leased
digital telecommunications lines. By combining the @Network's distributed
architecture with cable, telephone and technology relationships, the @Work
services provide a compelling platform for nationwide delivery of network-based
business applications. The Company has developed this platform at a low
incremental cost by leveraging its existing @Network investment.     
   
  The Company has entered into distribution arrangements for the @Home service
with affiliates of Tele-Communications, Inc. ("TCI"), Comcast Corporation
("Comcast"), Cox Enterprises, Inc. ("Cox"), Rogers Cablesystems Limited
("Rogers"), Shaw Cablesystems Ltd. ("Shaw"), Marcus Cable Operating Company,
L.P. ("Marcus") and InterMedia Partners IV L.P. ("Intermedia") (collectively,
together with their affiliates, the "Cable Partners"), whose cable systems
"pass" (i.e., can be connected to) approximately 44 million homes in North
America. The Company believes that approximately two million of these homes are
currently passed by upgraded two-way HFC cable and that the Cable Partners will
complete the upgrade of systems passing a majority of these homes within five
years. The Company has launched its service through TCI, Comcast, Cox
(collectively, the "Principal Cable Stockholders") and Intermedia in portions
of 13 cities and communities (of which 11 have revenue-paying subscribers) in
the United States. To expand distribution, the Company is aggressively seeking
to work with additional United States and international cable system operators.
In order to shorten time to market for cable operators, the Company provides a
turnkey solution, which includes not only a technology platform, but also
marketing, customer service, billing and a national brand. According to Paul
Kagan Associates, Inc., cable is available to approximately 97% of the homes in
the United States, and, according to Baskerville Communications, there will be
approximately 203 million homes passed in Europe and the Asia Pacific region in
the year 2000.     
   
  The Company was founded in March 1995 on the premise that the cable
infrastructure could enable the fastest, most cost-effective delivery mechanism
for residential Internet services but that the actual speed of these services
would ultimately be limited by the fundamental architecture of the Internet. As
a result, the Company assembled a team of industry experts to develop an
advanced network architecture and the custom hardware and software products
that would address these limitations. Prior to launching the @Home service in
September 1996, the Company implemented a nationwide backbone, designed and
built its Network Operations Center with 24X7 end-to-end management
capabilities, deployed regional data centers and headend equipment, implemented
an integrated customer management system including billing and support for
those operators that elect to obtain such services from the Company,
implemented a customized browser and aggregated the multimedia content required
to deliver the @Home Experience to its first subscribers.

                                 RISK FACTORS
   
  In addition to the other information in this Prospectus, the following
factors should be considered carefully in evaluating an investment in the
Shares of Series A Common Stock offered hereby. This Prospectus contains
forward-looking statements that involve risks and uncertainties. The Company's
actual results may differ materially from the results discussed in such
forward-looking statements. Factors that may cause such a difference include,
but are not limited to, those discussed below and in the sections entitled
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business."     
   
  Short Operating History; History of Losses; Unproven Business Model; No
Assurance of Profitability. The Company was incorporated in March 1995,
commenced operations in August 1995 and has incurred substantial net losses in
each fiscal period since its inception. As of March 31, 1997, the Company had
an accumulated deficit of $38.2 million. In addition, the Company currently
intends to increase its capital expenditures and operating expenses in order
to expand its network to support additional expected subscribers in existing
and future markets and to market and provide the Company's services to a
growing number of potential subscribers. As a result, the Company expects to
incur additional substantial operating and net losses for the foreseeable
future. The profit potential of the Company's business model is unproven, and,
to be successful, the Company must, among other things, develop and market
products and services that are widely accepted by consumers and businesses at
prices that will yield a profit. The Company's @Home service has only recently
been launched in portions of 13 cities and communities (of which 11 have
revenue-paying subscribers) in the United States, and there can be no
assurance that it will achieve broad consumer or commercial acceptance.
Currently, the Company has only approximately 6,000 subscribers to its @Home
service in these areas. Because it is a consumer service, the success of the
Company's @Home service will depend upon the willingness of subscribers to pay
the monthly fees and installation costs of the @Home service, both of which
are set by local cable system operators ("LCOs") and not by the Company. The
@Home service is currently priced at a premium to many other online services,
and there can be no assurance that large numbers of subscribers will be
willing to pay a premium for the @Home service. Accordingly, it is difficult
to predict whether the Company's pricing model will prove to be viable,
whether demand for the Company's services will materialize at the prices it
expects the LCOs to charge or whether current or future pricing levels will be
sustainable. If such pricing levels are not achieved or sustained or if the
Company's services do not achieve or sustain broad market acceptance, the
Company's business, operating results and financial condition will be
materially adversely affected. The Company's ability to generate future
revenues will be dependent on a number of factors, many of which are beyond
the Company's control, including, among others, the rate at which its current
and future cable partners upgrade their cable infrastructures, the success of
the LCOs in marketing the @Home service to subscribers in their local cable
areas and the prices that the LCOs set for the @Home service and its
installation. Because of the foregoing factors, among others, the Company is
unable to forecast its revenues with any degree of accuracy. There can also be
no assurance that the Company will ever achieve profitability. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and "Business--Strategy."     
   
  Potential Fluctuations in Quarterly Operating Results. The Company's
quarterly operating results may fluctuate significantly in the future as a
result of a variety of factors, many of which are outside the Company's
control. Factors that may affect the Company's quarterly operating results
attributable to its @Home service include the timing of Cable Partners'
upgrades of their cable infrastructures and rollouts of the @Home service, the
rate at which customers subscribe to the Company's Internet services and the
prices subscribers pay for such services, subscriber churn rates, changes in
the revenue splits between the Company and the Cable Partners, the demand for
Internet advertising, the effectiveness of the LCOs' marketing and other
operations, and potential competition with LCOs for advertising revenue.
Quarterly operating results attributable to the Company's @Work services are
dependent on the timing of Cable Partners' upgrades of their cable
infrastructures and rollouts of the @Home service, the demand for, and level
of acceptance of, the Company's corporate Internet, intranet and extranet
connectivity and telecommuting solutions and the introduction of, demand for,
and level of acceptance of, the Company's value-added business applications.
Additional factors that may affect the Company's quarterly operating results
generally include the amount and timing of capital expenditures and other     
 
                                       5

costs relating to the expansion of the Company's network, the introduction of
new Internet and telecommuting services by the Company or its competitors,
price competition or pricing changes in the Internet, cable and telecommuting
industries, technical difficulties or network downtime, general economic
conditions and economic conditions specific to the Internet, Internet media,
corporate intranet and cable industries. The Company operates with very little
backlog, and quarterly sales and operating results are difficult to forecast
even in the short term. There can be delays in the commencement and
recognition of revenue because the installation of telecommunication lines to
implement certain services has lead times that are controlled by third
parties. A significant portion of the Company's expenses are fixed in advance
based in large part on future revenue forecasts. If revenue is below
expectations in any given quarter, the adverse impact of the shortfall on the
Company's operating results may be magnified by the Company's inability to
adjust spending to compensate for the shortfall. Therefore, a shortfall in
actual as compared to estimated revenue would have an immediate adverse effect
on the Company's business, financial condition and operating results that
could be material. In addition, the Company plans to increase operating
expenses to fund additional research and development, sales and marketing,
general and administrative activities and infrastructure. To the extent that
these expenses are not accompanied by an increase in revenues, the Company's
business, operating results and financial condition could be materially
adversely affected. Due to all of the foregoing factors, it is likely that the
Company's operating results in one or more future quarters will fail to meet
or exceed the expectations of securities analysts or investors. In such event,
the trading price of the Series A Common Stock would likely be materially
adversely affected. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations."     
   
  Control by TCI; Veto Power of Other Principal Stockholders. The purchasers
of Series A Common Stock in this offering will not have sufficient voting
power to elect any members of the Company's Board of Directors (the "Board").
Following this offering, TCI will control approximately 72.2% of the voting
power of the Company and will have the power to elect a majority of the
members of the Board and the power to control all matters requiring the
approval of the holders of the Company's Common Stock voting together as a
single class. TCI owns all of the Series B Common Stock, which carries ten
votes per share and has the right under the Company's Certificate of
Incorporation (the "Certificate") to elect five directors (the "Series B
Common Stock Directors"), of which, pursuant to a Stockholders' Agreement,
three are to be designated by TCI, one is to be designated by Comcast and one
is to be designated by Cox. Currently, four of the Company's 11 directors are
directors, officers or employees of TCI or its affiliates. The Company's
Certificate provides that so long as TCI owns at least 7,700,000 shares of
Series B Common Stock and securities representing a majority of the
outstanding voting power of the Company, (i) any action by the Company's Board
must be approved by both a majority of directors present at a meeting at which
a quorum is present and by a majority of the Series B Common Stock Directors
(of which TCI is currently entitled to elect three out of five) and (ii) a
committee composed of those Series B Common Stock Directors who are officers,
directors or employees of TCI will have the sole power (acting as a committee
of the Board and without the necessity of stockholder approval) to increase
the size of the Board (up to a maximum of 17 members) and to fill the
vacancies created by any such increase. The effect of these provisions is to
enable TCI to block actions of the Board, even through the TCI directors may
not then constitute a majority of the Board, and to expand the Board at any
time and fill the vacancies with TCI designees such that the TCI designees
would constitute a majority of the Board. As a result, TCI, acting both
through its designees on the Board and through its ownership of voting
securities, will have the power to control the Company, subject, however, to
any fiduciary duties that TCI, as the controlling stockholder, may owe to the
other stockholders of the Company under Delaware law, the fiduciary duties
that all directors of the Company, including those directors who are officers
or directors of TCI, owe to stockholders of the Company to act in the best
interests of the stockholders and the supermajority and unanimous approval
provisions set forth in the Certificate which provide that the Company may not
take certain corporate actions without the approval of TCI's Series B Common
Stock Directors as well as two out of three, or in certain cases all three, of
the directors designated by Comcast, Cox and Kleiner Perkins Caufield & Byers
("KPCB"), which effectively gives Cox, Comcast and KPCB veto powers over
certain corporate actions. See "Management--Board Composition and Procedures,"
"Certain Transactions" and "Description of Capital Stock."

  Dependence on Cable Partners for Distribution; Potential Conflicts of
Interest with Principal Cable Stockholders. The Cable Partners are expected to
provide through certain of their cable systems the principal distribution
network for the Company's services to residential subscribers to the @Home
service (the majority of whom are expected to be subscribers to such Cable
Partners' cable television services) and will share the revenue from the @Home
services that are derived from such subscribers. Given the contractual and
business relationships between the Cable Partners and the Company, the
interests of the Cable Partners may not always coincide with the interests of
the Company, and conflicts of interest concerning the split of revenues and
other matters exist between the Company and the Principal Cable Stockholders,
who control the Company. Because TCI, Comcast and Cox all operate cable
systems that will be the primary distributors of the @Home service, situations
may arise where the interests of the Principal Cable Stockholders may diverge
or appear to diverge from the interests of the other stockholders of the
Company. TCI and the other Principal Cable Stockholders, acting through their
designees on the Board, will have the ability to cause the Company to take
certain actions or prohibit it from taking certain actions, which may be
favored by the other stockholders of the Company or by the other directors of
the Company who are not affiliated with the Principal Cable Stockholders. The
Board, which is controlled by TCI, has the power, subject to directors'
fiduciary duties, to approve transactions in which the Principal Cable
Stockholders have an interest, including a change in revenue splits in favor
of the Principal Cable Stockholders. Under the current master distribution
agreement pursuant to which the Principal Cable Stockholders distribute the
Company's services (the "Master Distribution Agreement"), the Company receives
35% of monthly fees and fees for premium services. As a result of certain
contractual "most favored nation" provisions (the "MFN"), which provide that
the cable affiliates of the Principal Cable Stockholders are entitled to
distribution arrangements and related services on terms at least as favorable
as those obtained by any other cable system operator, the Principal Cable
Stockholders could determine to cause the Company to approve more favorable
distribution arrangements, including more favorable revenue splits, for one or
more unaffiliated cable operators in order to receive more favorable
distribution arrangements for their respective cable affiliates through the
operation of the MFN. See "Management--Board Composition and Procedures."     
   
  Control by Principal Cable Stockholders of Terms of Distribution. Prior to
this offering, the Company and the Principal Cable Stockholders have entered
into the Master Distribution Agreement providing for the distribution of the
@Home service by the Principal Cable Stockholders and their affiliates. The
economic and other terms of the Master Distribution Agreement may be less
favorable to the Company than those that could have been negotiated had the
Company been independent of the Principal Cable Stockholders. Because the
Company does not yet have a significant number of subscribers, it is not yet
possible to determine whether the revenue splits and the other economic
aspects of the distribution of the Company's services will be sufficiently
attractive to encourage a sufficient number of cable system operators to enter
into distribution agreements with the Company, or to encourage cable system
operators, including the Principal Cable Stockholders, to incur the
substantial capital expenditures required to upgrade their cable systems to a
two-way HFC cable infrastructure and to roll out and vigorously promote the
@Home service. Because of their control of the Company, the Principal Cable
Stockholders will have the power, subject to their fiduciary duties, to change
any of the terms of distribution, including the revenue splits with the
Company. In addition, the Master Distribution Agreement and the other
agreements between the Company and the Principal Cable Stockholders contain
provisions that permit a Principal Cable Stockholder to change certain aspects
of the distribution of the @Home service without the approval of the Company.
For example, a Principal Cable Stockholder has the option to provide certain
customer service functions which are currently provided by the Company and
upon which the Company's 35% revenue split was based. If such Principal Cable
Stockholder elects to provide such services, it is also entitled to an
adjustment in the revenue split with the Company. Similarly, the Principal
Cable Stockholders have certain rights pursuant to the Master Distribution
Agreement to remove cable systems from the approved rollout schedule or
substitute cable systems in place of removed systems. These rights are
contractual in nature and may be exercised by the Principal Cable Stockholders
in their sole discretion. The exercise by the Principal Cable Stockholders of
these contractual rights may have an adverse effect upon the Company's
business, operating results and financial condition. Moreover, because of
their control of the Board, the Principal Cable Stockholders will have the
ability to amend, modify or terminate the Master Distribution Agreement,
agreements between LCOs affiliated with the Principal Cable Stockholders
("Affiliated LCOs") and the Company ("LCO Agreements"), a stockholders'     
 
                                       7
<PAGE>
 
   
agreement to which the Company and the Principal Cable Stockholders, among
others, are parties (the "Stockholders' Agreement") and the other agreements
to which the Company is a party, or to cause the Company to grant waivers of
certain provisions thereof. In considering any such amendments, modifications
or waivers, the members of the Board, including those members who are
designees of the Principal Cable Stockholders, will be subject to the
fiduciary duties owed to the stockholders of the Company under Delaware law.
There can be no assurance that following the consummation of this offering the
Principal Cable Stockholders will not cause the terms of the Master
Distribution Agreement to be amended, modified or terminated or cause the
Company to waive any provision of the Master Distribution Agreement. The
Principal Cable Stockholders control the Company and effectively determine the
rollout schedule of the @Home service. Moreover, the Master Distribution
Agreement and certain other agreements provide the Principal Cable
Stockholders and Rogers and Shaw with certain priority rights with respect to
the rollout schedule of the @Home service. This priority could adversely
affect the Company because the Company may be required to roll out its
services to the Principal Cable Stockholders and Rogers and Shaw, and their
respective LCOs, before rolling out the services to other cable system
operators, even though such other cable system operators may be ready to roll
out the @Home service sooner or on terms more favorable for the Company than
the terms of distribution for the Principal Cable Stockholders and Rogers and
Shaw, and their respective LCOs. See "Business--Strategic Distribution
Relationships--Strategic Relationships with Cable Partners" and "Certain
Transactions."     
   
  Right of Principal Cable Stockholders to Block Access to Certain Content and
Services. The Master Distribution Agreement provides each Principal Cable
Stockholder with the right to exclude the promotion of specified national
content providers from the @Home service offered through such Principal Cable
Stockholder's cable systems, subject to an adjustment in the split of premium
service revenues between the Principal Cable Stockholder and the Company to
the extent the number of such exclusions exceeds a specified number. In
addition, a Principal Cable Stockholder has the right to block access to
certain content, including streaming video segments of more than ten minutes
in duration, and the Company is obligated to use its reasonable best efforts
to block such access. The Company is obligated to use its reasonable best
efforts to consult with and involve each of the Principal Cable Stockholders
in the development of requirements for and design of enhancements, new
features and new applications of the @Home service and coordinate with respect
to the introduction of such enhancements, features and applications that could
have a significant effect on the operations of a Principal Cable Stockholder.
If Principal Cable Stockholders representing a majority of the residential
subscribers who subscribe to the @Home service via Affiliated LCOs of the
Principal Cable Stockholders object to such enhancement, feature or
application, the Company has agreed not to implement such enhancement, feature
or application in the territories of objecting Principal Cable Stockholders.
If any of the Principal Cable Stockholders exercise these rights to block
access to certain content or services in certain territories, the Company may
be required to devote substantial expenses and resources to provide different
content and services in different territories and to assist the Principal
Cable Stockholders in blocking such access, which could have a material
adverse effect on the Company's business, operating results and financial
condition. See "Certain Transactions--Certain Business Relationships."     
   
  No Obligation of Principal Cable Stockholders to Carry the Company's
Services; Limitations on Their Exclusivity. Although the Principal Cable
Stockholders and their Affiliated LCOs are subject to certain exclusivity
obligations under the Master Distribution Agreement that prohibit them from
obtaining high-speed (greater than 128 kilobits per second ("Kbps"))
residential consumer Internet services from any source other than the Company,
the Principal Cable Stockholders and their Affiliated LCOs are under no
affirmative obligation to carry any of the Company's services. Accordingly,
the termination of these exclusivity obligations could adversely affect the
willingness of the Principal Cable Stockholders to roll out or continue to
carry the Company's @Home and other services, which could have a material
adverse effect on the Company's business, operating results and financial
condition. The Principal Cable Stockholders' and their Affiliated LCOs'
exclusivity obligations in favor of the Company expire on June 4, 2002, and
may be terminated sooner under the following circumstances: (i) any Affiliated
LCO may terminate its exclusivity obligations if the Company fails to roll out
the @Home service in such operator's territory by the deadlines set forth in
the rollout schedules; (ii) the Principal Cable Stockholders may terminate all
exclusivity obligations upon a change in law that     
 
                                       8

materially impairs certain of the Principal Cable Stockholders' rights; (iii)
Comcast or Cox may terminate all Principal Cable Stockholders' exclusivity
obligations at any time if there is a change of control of TCI or on June 4,
1999 or each anniversary thereafter if certain subscriber penetration levels
for the @Home service are not met by TCI and its affiliates; and (iv) Comcast
may terminate its own exclusivity obligations upon its election after June 4,
1999 if it permits a portion of its equity in the Company to be repurchased by
the Company at Comcast's original cost. Comcast has informed the Company that
Comcast has entered into an agreement with Microsoft Corporation ("Microsoft")
pursuant to which Microsoft can require Comcast to terminate its exclusivity
obligations after June 4, 1999. Although Microsoft has stated in the agreement
that it has no present intention to do so, there can be no assurance that
Microsoft will not be more likely than Comcast to terminate Comcast's
exclusivity obligations. The exclusivity obligations of the Principal Cable
Stockholders in the Master Distribution Agreement also are subject to
exceptions that would permit the Principal Cable Stockholders and their
affiliates to engage in certain activities which could compete, directly or
indirectly, with the activities of the Company; for example, each Principal
Cable Stockholder and its affiliates is permitted to (i) engage in any
business other than the provision of high-speed residential consumer Internet
services, including competing with the Company's @Work operations, (ii)
maintain voting equity interests of 10% or less in public companies that do
directly compete with the Company's @Home service and related Internet
backbone connectivity services, (iii) acquire an interest in any business that
competes with the Company's high-speed residential consumer Internet services
(so long as the competitive business is not such entity's primary business and
subject to a limited obligation to divest the competing business on reasonable
terms, such divestiture subject to a right of first refusal by the Company),
(iv) acquire equity securities of public companies that compete with the
Company, provided that the Principal Cable Stockholder does not control (or is
not under common control with) such companies and (v) operate a competing
business in any cable system territory where the exclusivity obligations to
the Company have been terminated. See "Business--Strategic Distribution
Relationships--Strategic Relationships with Cable Partners" and "Certain
Transactions."     
   
  Rights of Principal Cable Stockholders and Limitations on the Company's
Ability to Provide Certain Excluded Services. The Master Distribution
Agreement provides that the Principal Cable Stockholders' exclusivity
obligations are limited to high-speed residential consumer Internet services,
and therefore the Company will not necessarily have access to their cable
systems for other services that the Company may wish to offer. The Principal
Cable Stockholders' exclusivity obligations do not apply to the creation or
aggregation of content or, among other things, any of the following services
(the "Excluded Services"): (i) the provision of telephony services, (ii) the
provision of services that are primarily work-related, such as @Work services,
(iii) the provision of Internet services that do not use their cable
television infrastructures, (iv) the provision of any local Internet service
that does not require use of an Internet backbone outside a single
metropolitan area, (v) the provision of services that are utilized primarily
to connect students to schools, colleges or universities, (vi) the provision
of Internet telephony, Internet video telephony or Internet video
conferencing, (vii) the provision of certain limited Internet services
primarily intended for display on a television, (viii) the provision of
certain Internet services that are primarily downstream services where the
user cannot send upstream commands in real-time as defined in the Master
Distribution Agreement, (ix) the provision of streaming video services that
include video segments longer than ten minutes in duration or (x) limited
testing, trials and similar activities of less than six months. Until the
later of such time as the applicable Principal Cable Stockholder ceases to be
obligated under the exclusivity provisions set forth above or, if the
exclusivity provisions are terminated by reason of TCI's failure to meet
specified subscriber penetration levels, June 4, 2002, the Company has agreed
(i) not to offer or provide Internet services at data transmission speeds
greater than 128 Kbps to residences in any geographic area served by the cable
systems of a Principal Cable Stockholder that remains in compliance with the
exclusivity provisions without regard to whether the "Restricted Period," as
defined in the Master Distribution Agreement, has ended as to such Principal
Cable Stockholder (the "Exclusive Territory") and (ii) not to directly or
indirectly offer, provide, distribute, advertise, promote or market (or carry
or otherwise distribute advertising or promotions with respect to) any
streaming video transmissions that include video segments longer than ten
minutes in duration or any other Excluded Service to residences in the
Exclusive Territory of a Principal Cable Stockholder without its prior written
consent even if such Excluded Service has been integrated with the @Home
service in other areas. Moreover, no assurance can be given that the Company
will have access to the cable infrastructures     
 
                                       9
<PAGE>
 
   
of the Principal Cable Stockholders or other Cable Partners for such Excluded
Services, and the Company must negotiate a separate agreement with the
Principal Cable Stockholders for each portion of such services that the
Company seeks to provide over their cable infrastructures. Any such denial of
access or exclusion, or competition from Principal Cable Stockholders in
providing Excluded Services, could have a material adverse effect on the
Company's business, operating results and financial condition. See "Business--
Strategic Distribution Relationships--Strategic Relationships with Cable
Partners" and "Certain Transactions."     
   
  Potential Disposition of Cable Systems by Principal Cable Stockholders. The
Company's agreements with its Principal Cable Stockholders do not require that
such Principal Cable Stockholders maintain a specified number of cable
systems, subscribers or homes passed by cable infrastructure in order to
maintain their control over and equity ownership of the Company. However, the
Stockholders' Agreement does provide that if a Principal Cable Stockholder's
number of homes passed which remain subject to certain exclusivity provisions
in favor of the Company decreases by more than 20% of the number of homes
passed as of June 4, 1996 (subject to certain exceptions), then such Principal
Cable Stockholder must offer to sell a proportionate amount of its equity
interest in the Company to the other Principal Cable Stockholders at the fair
market value thereof. However, such provisions would permit the disposition of
a portion of such Principal Cable Stockholders' cable assets without imposing
any penalty and, in the event a Principal Cable Stockholder exceeds the 20%
threshold, selling shares at fair market value may not constitute a
significant penalty to such Principal Cable Stockholder. Therefore, there can
be no assurance that such arrangements will effectively discourage a Principal
Cable Stockholder from disposing of a significant amount of its cable systems
without requiring that such cable systems remain subject to such exclusivity
provisions. TCI has recently announced the proposed sale to Cablevision
Systems Corporation of 10 cable systems in New York and New Jersey, and to
Adelphia Communications Corporation ("Adelphia") of certain cable systems in
Buffalo, N.Y. The cable systems proposed to be transferred in these
transactions have approximately 1.1 million and 260,000 homes passed,
respectively. In addition, TCI has announced that it is considering various
plans and proposals that may result in the disposition of other of its cable
systems. To the extent that the terms of any such transactions require that
such systems remain subject to such exclusivity provisions, such cable systems
and their homes passed would continue to be included in TCI's homes passed for
purposes of determining whether or not TCI is obligated to offer a portion of
its equity interest in the Company to the other Principal Cable Stockholders,
even though such cable systems are no longer owned or controlled by TCI. To
the extent that the Principal Cable Stockholders dispose of cable systems in
the future without causing such cable systems to remain subject to such
exclusivity provisions, the number of homes passed that are exclusive to the
Company will be decreased. Such decreases in the number of exclusive homes
passed may have an adverse effect upon the business, operating results and
financial condition of the Company.     
   
  Dependence on Cable Partners to Upgrade to Two-Way Cable Infrastructure
Necessary to Support the @Home Service; Uncertain Availability and Timing of
Upgrades. Transmission of the @Home service over cable is dependent on the
availability of high-speed two-way HFC cable infrastructure. However, only a
small portion of existing cable plant in the United States has been upgraded
to HFC cable and even less is capable of high-speed two-way transmission. The
Cable Partners and other cable system operators have announced and begun to
implement major infrastructure investments in order to deploy two-way HFC
cable. However, cable system operators have limited experience with these
upgrades, and these investments have placed a significant strain on the
financial, managerial, operating and other resources of the Cable Partners and
other cable system operators, most of which are already highly leveraged, and
thus have been, and the Company expects will continue to be, subject to
change, delay or cancellation. Although the Company's commercial success
depends on the successful and timely completion of these infrastructure
upgrades, the Cable Partners are under no obligation to the Company to upgrade
systems or to roll out, market or promote the Company's services. In addition,
none of the Cable Partners has agreed to any specific schedule for rolling out
two-way HFC infrastructure improvements, and the Cable Partners are not
contractually required to achieve any specific rollout schedule. Because of
the very substantial capital cost of upgrading cable systems for high-speed
two-way data transmission, there has been uncertainty in recent months as to
the rate at which the Cable Partners and other cable system operators will
upgrade their systems. For example, to increase television programming
capacity to compete with other modes of multichannel entertainment delivery
systems such as direct satellite, the Cable     
 
                                      10
<PAGE>
 
   
Partners may choose to roll out digital set-top boxes, which do not support
high-speed Internet access services, rather than to upgrade their cable
infrastructures to two-way HFC cable.  The failure of the Cable Partners to
complete these upgrades in a timely and satisfactory manner, or at all, would
prevent the Company from delivering high-performance Internet access services
and would have a material adverse effect on the Company's business, operating
results and financial condition.  To the extent that the Company is required
(because of the lack of upgraded two-way HFC cable plant), or together with the
Cable Partners otherwise chooses, to distribute the Company's services through
cable systems to the home with a telephone return path for data from the home,
the Company's services may not achieve the high speed and quality of experience
necessary to attract and retain subscribers to the @Home service.  Subscribers
using a telephone return path will experience the upstream data transmission
speeds provided by their analog modems (typically 28.8 Kbps).  In addition, the
Company will be highly dependent on the Cable Partners and any future cable
partners to continue to maintain their cable infrastructure in such a manner
that the Company will be able to provide consistently high performance and
reliable service.  Therefore, in addition to the Company's business being
subject to general economic and market conditions and factors relating to
Internet service providers and online services specifically, the success and
future growth of the Company's business will also be subject to economic and
other factors affecting the cable television industry generally, particularly
its ability to finance substantial capital expenditures. See "Business--
Strategy," "--Products and Services," "--@Network Architecture" and "--Strategic
Distribution Relationships--Strategic Relationships with Cable Partners."     
   
  Dependence on Cable Partners to Roll Out, Market, Install, Maintain
Infrastructure for, Provide Customer Service for and Bill for the @Home
Service. In order to roll out the @Home service in a geographic area, the
Cable Partners must have completed the two-way HFC cable infrastructure
upgrade in that area. Following the rollout of the @Home service in a service
area, the Company's business will be highly dependent on the LCO to maintain
its cable infrastructure in such a manner as to permit the reliable
transmission of the @Home service. Because subscribers to the @Home service
will subscribe through an LCO, the LCO (and not the Company) will
substantially control the customer relationship with the subscriber. Each LCO
has complete discretion regarding the pricing of @Home service to subscribers
in its territory (except for certain premium services for which the Company
contracts directly with the subscriber), and an LCO could use the @Home
service as a loss leader in order to increase demand for other LCO products or
services with more attractive terms for the LCO. Neither the Cable Partners
nor their LCOs have any affirmative obligations (other than the payment of
revenue splits to the Company) with respect to marketing, installing and
maintaining infrastructure for, providing customer service for and billing for
the @Home service, and the Company has no remedies against the Cable Partners
or their LCOs, other than in limited circumstances such as an LCO's failure to
upgrade its cable system or roll out the @Home service after it has committed
to do so, in which event the Company may be entitled to certain cost
reimbursements and release from its exclusivity obligations to such LCO,
neither of which may be an effective remedy for the Company. Moreover, the
Master Distribution Agreement does not create affirmative obligations on the
part of any Principal Cable Stockholder to cause its Affiliated LCOs to
perform any of the foregoing activities or to upgrade any of their cable
systems. The Company's business model requires that a material number of LCOs
of all its Cable Partners roll out the @Home service, and if a sufficient
number of LCOs does not roll out the @Home service, the Company's business
model will not be viable. Each of the Principal Cable Stockholders and its
Affiliated LCOs is entitled to MFN terms with respect to the distribution of
the @Home service, subject to certain exceptions. These terms could limit the
Company's ability to negotiate agreements with other cable system operators
and otherwise could limit the Company's potential to generate revenue. The
Affiliated LCOs are expected to provide general customer service to the
Company's subscribers and, pursuant to the distribution agreements with the
Company, have the option to provide technical support, rather than utilizing
the Company's service and support capabilities. If an Affiliated LCO elects to
provide technical support, the LCO Agreement provides for an adjustment in the
revenue split between the Company and the Affiliated LCO, and the Company
would have little or no control over the quality of customer service actually
provided to subscribers of the @Home service. If the customer service and
support provided by Affiliated LCOs are unsatisfactory to subscribers,
consumer demand for the Company's @Home service will likely be materially
adversely affected. See "Business--Strategic Distribution Relationships--
Strategic Relationships with Cable Partners."     
 
                                      11

  Potential Competition with Cable Partners for Advertising Revenue. While the
Company retains 100% of all United States national advertising revenue
delivered on the @Home service through the Company's U.S. Cable Partners, LCOs
of the U.S. Cable Partners retain 100% of revenue generated from local service
offerings that do not require access to an Internet backbone or that relate to
programming within the designated local areas of the home page for the @Home
service, such as revenues from advertising. In Canada, the Company will share
national advertising revenue with its Canadian Cable Partners. Moreover, given
the national coverage of the combined operations of the Principal Cable
Stockholders and their Affiliated LCOs, the Principal Cable Stockholders and
their Affiliated LCOs could strike agreements with advertisers that would
effectively result in broad-based advertising campaigns throughout most of the
United States in competition with the Company's national advertising
campaigns, generating revenue only for Affiliated LCOs and not for the
Company. Accordingly, the @Home service may contain a significant amount of
advertising that is national in scope and focus for which it receives no share
of the revenues. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations" and "Business--Strategic Distribution
Relationships--Strategic Relationships with Cable Partners."     
   
  Dependence on TCG for Local Telecommunications Services for the @Work
Services. The Company depends on Teleport Communications Group Inc. ("TCG"),
which, like the Company, is also controlled by TCI, Comcast and Cox, to
provide local telecommunications services and co-location within TCG's
facilities on favorable economic terms that enable the Company to provide
@Work services to an entire metropolitan area in which TCG has facilities. If
the Company were required to obtain comparable telecommunications services
from local exchange carriers, it would effectively be limited to providing
@Work services to commercial customers within a ten-mile radius of one of the
Company's points of presence. As a result, the Company would be required to
build multiple points of presence to service an entire metropolitan area,
which would substantially increase the Company's capital costs to enter new
markets and which could make such market entry uneconomical for the Company.
If the Company were required to pay standard local exchange carrier rates, the
Company's ongoing operating costs for its @Work services would be
substantially higher. The loss of the Company's strategic relationship with
TCG would have a material adverse effect on the Company's ability to deploy
its @Work services and on its business, operating results and financial
condition. In addition, TCG has acquired a provider of Internet-related
services to businesses and corporate customers and will compete directly with
the @Work Internet service, and to the extent TCG acquires or enters into
strategic relationships with other Internet service providers ("ISPs"), TCG
may reduce its support of the @Work services. Although there are alternative
suppliers for TCG's services, it could take a significant period of time to
establish similar relationships and equivalent terms might not be available.
See "Business--Strategic Distribution Relationships--Strategic Relationship
with TCG."     
   
  Unproven Network Scalability and Speed. Due to the limited deployment of the
Company's services, the ability of the @Network to connect and manage a
substantial number of online subscribers at high transmission speeds is as yet
unknown, and the Company faces risks related to the @Network's ability to be
scaled up to its expected subscriber levels while maintaining superior
performance. While peak downstream data transmission speeds across HFC cable
approach 27 megabits per second ("Mbps") in each 6 MHz channel, the actual
downstream data transmission speeds over the @Network could be significantly
slower and will depend on a variety of factors, including type and location of
content, Internet traffic, the number of active subscribers on a given cable
network node, the number of 6 MHz channels allocated by the LCO (in its
discretion) to carry the Company's services, the capability of cable modems
used and the service quality of the LCOs' two-way HFC cable infrastructures.
As subscriber penetration increases, it may be necessary for the LCO to add
additional nodes in order to maintain adequate downstream data transmission
speeds although there is no obligation for the LCO to do so. The upstream
transmission data carrier is located in a range not used for broadcast by
traditional cable infrastructures and is more susceptible to interference than
the downstream channel, resulting in a slower peak upstream transmission
speed. In addition to the factors affecting downstream data transmission
speeds, actual upstream data transmission speeds over the @Network can be
materially affected by the level of interference in the LCOs' upstream data
broadcast range. The actual data delivery speeds that can be realized by
subscribers will be significantly lower than peak data transmission speeds due
to the subscriber's hardware, operating system and software configurations. To
access the @Home service, subscribers need a personal     
 
                                      12
<PAGE>
 
computer with at least a 66 MHz 486 or equivalent microprocessor and 16
megabytes of main memory. There can be no assurance that the @Network will be
able to achieve or maintain such a high speed of data transmission, especially
as the number of the Company's subscribers grows, and the Company's failure to
achieve or maintain high-speed data transmission would significantly reduce
consumer demand for its services and have a material adverse effect on its
business, operating results and financial condition. See "Business--@Network
Architecture."
 
  Dependence on High-Quality Content Provision and Acceptance; Developing
Market for High-Quality Content. A key component of the Company's strategy is
to provide a more compelling interactive experience to Internet users than the
experience currently available from dial-up ISPs and online service providers
("OSPs"). The Company believes that, in addition to providing high-speed,
high-performance Internet access, it must also promote the development of and
aggregate high-quality multimedia content. The Company's success in providing
and aggregating such content is dependent on its ability to motivate content
providers to create and support high-quality, high-speed multimedia content
and its ability to aggregate content offerings in a manner that subscribers
find useful and compelling and will be dependent, in part, on the Company's
ability to develop a customer base sufficiently large to justify investments
in the development of such content. There can be no assurance that the Company
will be successful in these endeavors. In addition, the market for high-
quality multimedia Internet content has only recently begun to develop and is
rapidly evolving, and there is significant competition among ISPs and OSPs for
aggregating such content. If the market fails to develop or develops more
slowly than expected, or if competition increases, or if the Company's content
offerings do not achieve or sustain market acceptance, the Company's business,
operating results and financial condition will be materially adversely
affected. See "Business--Strategy" and "--Products and Services."
   
  Uncertain Acceptance and Maintenance of the "@Home" Brand. The Company
believes that establishing and maintaining the "@Home" brand are critical to
attracting and expanding its subscriber base. Promotion of the "@Home" brand
will depend, among other things, on the Company's success in providing high-
speed, high-quality consumer and business Internet products, services and
content, the marketing efforts of the LCOs, and the reliability of the LCOs'
networks and services, none of which can be assured. The Company has no
control over the LCOs' marketing efforts or the reliability of their networks
and services. If consumers and businesses do not perceive the Company's
existing products and services to be of high quality, or if the Company
introduces new products or services or enters into new business ventures that
are not favorably received by consumers and businesses, the Company will be
unsuccessful in promoting and maintaining its brand. To the extent the Company
expands the focus of its marketing efforts to geographic areas where the @Home
service is not available, the Company risks frustrating potential subscribers
who are not able to access the Company's products and services. Furthermore,
in order to attract and retain subscribers, and to promote and maintain the
"@Home" brand in response to competitive pressures, the Company may find it
necessary to increase substantially its financial commitment to creating and
maintaining a distinct brand loyalty among customers. If the Company is unable
to establish or maintain the "@Home" brand successfully, or if the Company
incurs excessive expense in an attempt to improve its offerings or promote and
maintain its brand, the Company's business, operating results and financial
condition would be materially adversely affected. See "Business--Strategy" and
"--Distribution, Marketing and Sales."     
 
  Management of Expanded Operations; Dependence on Key Personnel. The Company
may not be equipped to successfully manage any future periods of rapid growth
or expansion, which could be expected to place a significant strain on the
Company's managerial, operating, financial and other resources. The Company is
highly dependent upon the efforts of its senior management team, and the
Company's future performance will depend, in part, upon the ability of senior
management to manage growth effectively, which will require the Company to
implement additional management information systems capabilities, to develop
further its operating, administrative, financial and accounting systems and
controls, to maintain close coordination among engineering, accounting,
finance, marketing, sales and operations, and to hire and train additional
technical and marketing personnel. There is intense competition for senior
management, technical and marketing personnel in the areas of the Company's
activities. The loss of the services of any of the Company's senior management
team or the failure to attract and retain additional key employees could have
a material adverse effect on the Company's business, operating results and
financial condition. The Company maintains no key-person life insurance. See
"Management."

  Competition. The markets for consumer and business Internet services and
online content are extremely competitive, and the Company expects that
competition will intensify in the future. The Company's most direct
competitors in these markets are ISPs, national long distance carriers and
local exchange carriers, wireless service providers, OSPs and Internet content
aggregators. Many of these competitors are offering (or may soon offer)
technologies that will attempt to compete with some or all of the Company's
high-speed data service offerings. Such technologies include Integrated
Services Digital Network ("ISDN") and Digital Subscriber Line ("xDSL"). The
Company also competes with other cable-based data services that are seeking to
contract with cable system operators to bring their services into geographic
areas that are not covered by an exclusive relationship between the Company
and its Principal Cable Stockholders. The bases of competition in these
markets include transmission speed, reliability of service, ease of access,
price/performance, ease-of-use, content quality, quality of presentation,
timeliness of content, customer support, brand recognition, operating
experience and revenue sharing.     
 
  ISPs, such as BBN Corporation ("BBN"), Earthlink Network, Inc.
("Earthlink"), MindSpring Enterprises, Inc. ("MindSpring"), Netcom On-Line
Communications Services, Inc. ("Netcom") and PSInet Inc. ("PSInet"), provide
basic Internet access to residential consumers and businesses, generally using
existing telephone network infrastructures. This method is widely available
and inexpensive. Barriers to entry are low, resulting in a highly competitive
and fragmented market.
 
  Long distance inter-exchange carriers, such as AT&T Corp. ("AT&T"), MCI
Communications Corporation ("MCI"), Sprint Corporation ("Sprint") and
WorldCom, Inc. ("WorldCom"), have deployed large-scale Internet access
networks and sell connectivity to business and residential customers. The
regional Bell operating companies ("RBOCs") and other local exchange carriers
have also entered this field and are providing price competitive services.
Many of such carriers are offering diversified packages of telecommunications
services, including Internet access service, to residential customers and
could bundle such services together, which could place the Company at a
competitive disadvantage.
 
  Wireless service providers, including AT&T and Hughes Network Systems, are
developing wireless Internet connectivity, such as multichannel multipoint
distribution service, local multipoint distribution service and digital
broadcast satellite.
   
  OSPs include companies such as America Online, Inc. ("America Online"),
CompuServe Corporation ("CompuServe"), Microsoft Corporation's Microsoft
Network ("MSN"), Prodigy, Inc. ("Prodigy") and WebTV Networks Inc. ("WebTV")
(which has agreed to be acquired by Microsoft Corporation) that provide, over
the Internet and on proprietary online services, content and applications
ranging from news and sports to consumer video conferencing. These services
are designed for broad consumer access over telecommunications-based
transmission media, which enables the provision of data services to the large
group of consumers who have personal computers with modems. In addition, they
provide basic Internet connectivity, ease-of-use and consistency of
environment. In addition to developing their own content or supporting
proprietary third-party content developers, online services often establish
relationships with traditional broadcast and print media outlets to bundle
their content into the service, such as the relationship of Microsoft with NBC
to provide multimedia news and information programming over both cable
television and MSN.     
 
  Content aggregators seek to provide a "one-stop" shop for Internet and
online users. Their success depends on capturing audience flow, providing
ease-of-use and offering a range of content that appeals to a broad audience.
Their business models are predicated on attracting and retaining an audience
for their set of offerings. Leading companies in this area include America
Online, CompuServe, Excite, Inc. ("Excite"), Microsoft and Yahoo! Inc.
("Yahoo!"). In this market, competition occurs in acquiring both content
providers and subscribers. The principal bases of competition in attracting
content providers include quality of demographics, audience size, cost-
effectiveness of the medium and ability to create differentiated experiences
using aggregator tools. The principal bases of competition in attracting
subscribers include richness and variety of content and ease of access to the
desired content. The proprietary online services such as America Online,
CompuServe and MSN have the advantage of a large customer base, industry
experience, many content partnerships and significant resources.

  The Company's competitors in the cable-based services market are those cable
companies that have developed their own cable-based services and market those
services to unaffiliated cable system operators that are planning to deploy
data services and with which the Company would like to work. Several cable
system operators, including Time Warner Inc. ("Time Warner") and the
Continental Cablevision subsidiary of U S WEST, Inc. ("US West"), have
deployed high-speed Internet access services over their existing local HFC
cable networks. Specifically, Time Warner, which is the second largest cable
company in the United States, has established its own cable-based ISP with
proprietary content, called Road Runner, which features a variety of Time
Warner publications and services. Time Warner plans to market the Road Runner
service through Time Warner's own cable systems as well as to other cable
system operators nationwide. Continental Cablevision has developed another
service called Highway One, which offers high-speed Internet services to its
existing customers. Others that have publicly announced limited-area trials
for their own cable-based Internet services include Adelphia, BellSouth
Corporation ("BellSouth") and Jones Intercable, Inc. ("Jones Intercable").
Some of these companies such as Time Warner have their own substantial
libraries of multimedia content and the other competitors could establish
strategic relationships with content providers, which could provide them with
a significant competitive advantage.     
 
  Many of the Company's competitors and potential competitors have
substantially greater financial, technical and marketing resources, larger
subscriber bases, longer operating histories, greater name recognition and
more established relationships with advertisers and content and application
providers than the Company. Such competitors may be able to undertake more
extensive marketing campaigns, adopt more aggressive pricing policies and
devote substantially more resources to developing Internet services or online
content than the Company. There can be no assurance that the Company will be
able to compete successfully against current or future competitors or that
competitive pressures faced by the Company will not materially adversely
affect the Company's business, operating results or financial condition.
Further, as a strategic response to changes in the competitive environment,
the Company may make certain pricing, service or marketing decisions or enter
into acquisitions or new ventures that could have a material adverse effect on
the Company's business, operating results or financial condition. See
"Business--Competition."
 
  Risk of System Failure. The Company's operations are dependent upon its
ability to support its highly complex network infrastructure and avoid damage
from fires, earthquakes, floods, power losses, telecommunications failures and
similar events. The occurrence of a natural disaster or other unanticipated
problem at the Company's Network Operations Center ("NOC") or at a number of
the Company's regional data centers ("RDCs") could cause interruptions in the
services provided by the Company. Additionally, failure of the Cable Partners
or TCG to provide the data communications capacity required by the Company, as
a result of natural disaster, operational disruption or any other reason,
could cause interruptions in the services provided by the Company. Any damage
or failure that causes interruptions in the Company's operations could have a
material adverse effect on the Company's business, operating results and
financial condition. See "Business--@Network Architecture."
 
  Risks of Technological Change. The markets for consumer and business
Internet access services and online content are characterized by rapid
technological developments, frequent new product introductions and evolving
industry standards. The emerging nature of these products and services and
their rapid evolution will require that the Company continually improve the
performance, features and reliability of its network, Internet content and
consumer and business services, particularly in response to competitive
offerings. There can be no assurance that the Company will be successful in
responding quickly, cost effectively and sufficiently to these developments.
There may be a time-limited market opportunity for the Company's cable-based
consumer and business Internet services, and there can be no assurance that
the Company will be successful in achieving widespread acceptance of its
services before competitors offer products and services with speed and
performance similar to the Company's current offerings. In addition, the
widespread adoption of new Internet or telecommuting technologies or
standards, cable-based or otherwise, could require substantial expenditures by
the Company to modify or adapt its network, products and services and could
fundamentally affect the character, viability and frequency of Internet-based
advertising, either of which could have a material adverse effect on the
Company's business, operating results and financial condition. In addition,
new Internet or telecommuting
 
                                      15
<PAGE>
 
services or enhancements offered by the Company may contain design flaws or
other defects that could have a material adverse effect on the Company's
business, operating results and financial condition. See "Business--Products
and Services," "--@Network Architecture" and "--Product Development and
Engineering."
   
  Dependence on Two-Way Cable Modems; Minimum Hardware Requirements. Each of
the Company's subscribers currently must obtain a cable modem from an
Affiliated LCO to access the @Home service. The inability of the Affiliated
LCOs to obtain a sufficient quantity of cable modems, or the inability of
subscribers to otherwise obtain cable modems, at acceptable price and
performance levels could delay or impair the expansion of the Company's
business. In addition, the Company's Cable Partners currently depend on a
limited number of suppliers, principally Motorola, Inc. ("Motorola") and Bay
Networks, Inc. ("Bay Networks"), for cable modems. The loss of such suppliers
or their inability to provide cable modems that meet the requirements of the
Company's services, would have a material adverse effect on the Company's
business, operating results and financial condition. In addition to a cable
modem, to access the @Home service, subscribers need a personal computer with
at least a 66 MHz 486 or equivalent microprocessor, 16 megabytes of main
memory and the ability to support an ethernet connection. See "Business--
@Network Architecture."     
 
  Dependence on Key Technology Suppliers. The Company currently depends on a
limited number of suppliers for certain key technologies used to build and
manage the @Network. In particular, the Company depends on Sun Microsystems,
Inc. ("Sun") for high availability servers, Silicon Graphics, Inc. ("SGI") for
caching servers, Cisco Systems, Inc. ("Cisco") for network routing and
switching hardware, Sprint for national switched ATM backbone services,
Objective Systems Integrators, Inc. ("OSI") for network management software,
Tivoli Systems Inc. ("Tivoli") for systems management software to operate RDCs
remotely, Oracle Corporation ("Oracle") for advanced database management
software and Netscape Communications Corporation ("Netscape") for server and
browser software. Although the Company believes that there are alternative
suppliers for each of these technologies, it could take a significant period
of time to establish relationships with alternative suppliers and substitute
their technologies into the @Network. The loss of any of the Company's
relationships with these suppliers could have a material adverse effect on the
Company's business, operating results and financial condition. See "Business--
@Network Architecture."
   
  Dependence on the Internet. Market acceptance of the Company's services is
substantially dependent upon the adoption of the Internet for commerce,
entertainment and communications. As is typical in the case of an emerging
industry characterized by rapidly changing technology, evolving industry
standards and frequent new product and service introductions, demand for and
market acceptance of recently introduced Internet products and services are
subject to a high level of uncertainty. In addition, critical issues
concerning the commercial use of the Internet remain unresolved and may affect
the growth of Internet use, especially in the business and consumer markets
targeted by the Company. Despite growing interest in the commercial
possibilities for the Internet, many businesses and consumers have been
deterred from purchasing Internet access services for a number of reasons,
including inconsistent quality of service, lack of availability of cost-
effective, high-speed service, a limited number of local access points for
corporate users, inability to integrate business applications on the Internet,
the need to deal with multiple and frequently incompatible vendors, inadequate
protection of the confidentiality of stored data and information moving across
the Internet and a lack of tools to simplify Internet access and use. The
adoption of the Internet for commerce and communications, particularly by
those individuals and enterprises that have historically relied upon
alternative means of commerce and communication, generally requires
understanding and acceptance of a new way of conducting business and
exchanging information. In particular, enterprises that have already invested
substantial resources in other means of conducting commerce and exchanging
information, or in relationships with other ISPs, may be reluctant and slow to
adopt a new strategy that may make their existing personnel, infrastructure
and ISP relationship obsolete. If the market fails to develop or develops more
slowly than expected, or if market competition increases, the Company's
business, operating results and financial condition may be materially
adversely affected. See "Business--Industry Background."     
 
  Security Risks. Despite the implementation of security measures, the
Company's or Affiliated LCOs' networks may be vulnerable to unauthorized
access, computer viruses and other disruptive problems. ISPs and
 
                                      16
<PAGE>
 
   
OSPs have in the past experienced, and may in the future experience,
interruptions in service as a result of the accidental or intentional actions
of Internet users, current and former employees or others. Unauthorized access
could also potentially jeopardize the security of confidential information
stored in the computer systems of the Company and its subscribers, which might
result in liability of the Company to its subscribers and also might deter
potential subscribers. Although the Company intends to continue to implement
industry-standard security measures, such measures have been circumvented in
the past, and there can be no assurance that measures implemented by the
Company will not be circumvented in the future. Moreover, the Company has no
control over the security measures that the Affiliated LCOs adopt. Eliminating
computer viruses and alleviating other security problems may require
interruptions, delays or cessation of service to the Company's subscribers,
which could have a material adverse effect on the Company's business,
operating results and financial condition. See "Business--Network
Architecture."     
   
  Government Regulation. Although the Company's services are not directly
subject to current regulations of the Federal Communications Commission (the
"FCC") or any other federal or state communications regulatory agency, changes
in the regulatory environment relating to the Internet connectivity market,
including regulatory changes that, directly or indirectly, affect
telecommunications costs, limit usage of subscriber-related information or
increase the likelihood or scope of competition from the RBOCs or other
telecommunications companies, could affect the prices at which the Company may
sell its services. For example, regulations recently adopted by the FCC are
intended to subsidize Internet connectivity rates for schools and libraries,
which could affect demand for the Company's services. The Company cannot
predict the impact, if any, that future regulation or regulatory changes might
have on its business. In addition, regulation of cable television rates may
affect the speed at which the Cable Partners upgrade their cable
infrastructures to two-way HFC. The Company's Cable Partners have advised the
Company that the LCOs typically have elected to classify the provision of all
or some of the Company's services as "additional cable services" under their
respective local franchise agreements, and to pay franchise fees in accordance
therewith. Local franchise authorities may attempt to subject the LCOs to
higher or other franchise fees or taxes or otherwise seek to require them to
obtain additional franchises in connection with their distribution of the
@Home service. There are thousands of franchise authorities in the United
States alone, and thus it will be difficult or impossible for the Company, its
Cable Partners or their LCOs to operate under a unified set of franchise
requirements. It is possible that governmental authorities may attempt to
impose additional fees or regulations on LCOs offering the Company's services.
In the event that the FCC or another governmental agency were to classify the
cable system operators as "common carriers" of Internet services, or cable
system operators were to seek such classification as a means of protecting
themselves against liabilities, the Company's rights as the exclusive ISP over
the systems of certain of the Cable Partners could be lost. In addition, if
the Company, the Cable Partners or their LCOs were classified as common
carriers, they could be subject to government-regulated tariff schedules for
the amounts they could charge for their services. Alternatively, the LCOs
could treat the provision of the Company's services as "information services"
under federal law. While the FCC does not, at present, regulate the provision
of information services, such services could, in the future, be the subject of
federal regulation, state regulation and/or special fees or taxes. Such
regulation could affect the willingness of LCOs to offer the Company's
services. Rogers and Shaw have informed the Company that, due to certain
Canadian regulations, they are required to provide access to their respective
networks to third-party ISPs, and that therefore the Company's services may
not have exclusive access to such networks. To the extent the Company
increases the number of foreign jurisdictions in which it offers its services,
the Company will be subject to additional governmental regulation. See "--
Risks Associated with International Operations" and "Business--Strategic
Distribution Relationships--Strategic Relationships with Cable Partners."     
 
  Potential Liability for Defamatory or Indecent Content. The law relating to
liability of ISPs and OSPs for information carried on or disseminated through
their networks is currently unsettled. A number of lawsuits have sought to
impose such liability for defamatory speech and indecent materials. A recent
federal statute seeks to impose such liability, in some circumstances, for
transmission of obscene or indecent materials. In one case, a court has held
that an OSP could be found liable for defamatory matter provided through its
service, on the ground that the service provider exercised active editorial
control over postings to its service. Other courts have held that ISPs and
OSPs may, under certain circumstances, be subject to damages for copying or
distributing
 
                                      17
<PAGE>
 
copyrighted materials. The Telecommunications Act of 1996 prohibits, and
imposes criminal penalties and civil liability for using, an interactive
computer service for transmitting indecent or obscene communications. A number
of states have adopted or are currently considering similar legislation. The
anti-indecency provisions of the Telecommunications Act of 1996 have been
declared unconstitutional by the United States District Courts for the Eastern
District of Pennsylvania and the Southern District of New York, which have
issued preliminary injunctions against their enforcement. The United States
Supreme Court has heard oral arguments on the appeal of those decisions. The
imposition upon ISPs or OSPs of potential liability for materials carried on
or disseminated through their systems could require the Company to implement
measures to reduce its exposure to such liability, which may require the
expenditure of substantial resources or the discontinuation of certain product
or service offerings. In addition, the imposition of liability on the Company
for information carried on the @Network could have a material adverse effect
on the Company's business, operating results and financial condition.
   
  Liability for Information Retrieved and Replicated. Because materials will
be downloaded and redistributed by subscribers and cached or replicated by the
Company in connection with the Company's offering of its services, there is a
possibility that claims may be made against the Company, the Cable Partners or
their Affiliated LCOs under both United States and foreign law for defamation,
negligence, copyright or trademark infringement, or other theories based on
the nature and content of such materials. Such types of claims have been
brought, and sometimes successfully pressed, against OSPs in the past. In
particular, copyright and trademark laws are evolving both domestically and
internationally, and there is uncertainty concerning how broadly the rights
afforded under these laws will be applied to online environments. It is
impossible for the Company to determine who all the potential rights holders
may be with respect to all materials available through the Company's services.
In addition, a number of third-party owners of patents have claimed to hold
patents that cover various forms of online transactions or online technology.
As with other OSPs, patent claims could be asserted against the Company based
upon its services or technologies. Although the Company carries general
liability insurance, the Company's insurance may not cover potential claims of
the foregoing types, or may not be adequate to indemnify the Company for all
liability that may be imposed. Any imposition of liability that is not covered
by insurance or is in excess of insurance coverage could have a material
adverse effect on the Company's business, operating results and financial
condition. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."     
   
  Risks Associated with International Operations. A key component of the
Company's strategy is expansion into international markets. To date, the
Company has developed relationships only with United States and Canadian cable
system operators. The Company has extremely limited experience in developing
localized versions of its products and services and in developing
relationships with international cable system operators. There can be no
assurance that the Company will be successful in expanding its product and
service offerings into foreign markets. In addition to the uncertainty
regarding the Company's ability to generate revenues from foreign operations
and expand its international presence, there are certain risks inherent in
doing business on an international level, such as regulatory requirements
(including the regulation of Internet access), legal uncertainty regarding
liability for information retrieved and replicated in foreign jurisdictions,
export and import restrictions, tariffs and other trade barriers, difficulties
in staffing and managing foreign operations, longer payment cycles, problems
in collecting accounts receivable, political instability, fluctuations in
currency exchange rates, seasonal reductions in business activity during the
summer months in Europe and certain other parts of the world and potentially
adverse tax consequences, which could adversely affect the success of the
Company's future international operations. There can be no assurance that one
or more of such factors will not have a material adverse effect on the
Company's future international operations and, consequently, on the Company's
business, operating results and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations" and
"Business--Distribution, Marketing and Sales."     
 
  Intellectual Property; Litigation. The Company regards its technology as
proprietary and attempts to protect it with copyrights, trademarks, trade
secret laws, restrictions on disclosure and other methods. In addition, the
Company has filed one patent application and is in the process of preparing
additional patent applications
 
                                      18
<PAGE>
 
with respect to aspects of its high-bandwidth network technology and online
advertising. There can be no assurance that any patent will issue from these
applications or that, if issued, any claims allowed will be sufficiently broad
to protect the Company's technology. In addition, there can be no assurance
that any patents that may be issued will not be challenged, invalidated or
circumvented, or that any rights granted thereunder would provide proprietary
protection to the Company. Failure of any patents to provide protection to the
Company's technology may make it easier for the Company's competitors to offer
technology equivalent or superior to the Company's technology. The Company
also generally enters into confidentiality or license agreements with its
employees and consultants, and generally controls access to and distribution
of its documentation and other proprietary information. Despite these
precautions, it may be possible for a third party to copy or otherwise obtain
and use the Company's products, services or technology without authorization,
or to develop similar technology independently. In addition, effective
copyright, trademark and trade secret protection may be unavailable or limited
in certain foreign countries, and the global nature of the Internet makes it
virtually impossible to control the ultimate destination of the Company's
content offerings. Policing unauthorized use of the Company's content
offerings is difficult. There can be no assurance that the steps taken by the
Company will prevent misappropriation or infringement of its technology. In
addition, litigation may be necessary in the future to enforce the Company's
intellectual property rights, to protect the Company's trade secrets or to
determine the validity and scope of the proprietary rights of others. Such
litigation could result in substantial costs and diversion of resources and
could have a material adverse effect on the Company's business, operating
results and financial condition.
 
  From time to time, the Company has received, and may receive in the future,
notice of claims of infringement of other parties' proprietary rights,
including claims for infringement resulting from the downloading of materials
by the online or Internet services operated or facilitated by the Company.
There can be no assurance that infringement or invalidity claims (or claims
for indemnification resulting from infringement claims) will not be asserted
or prosecuted against the Company or that any assertions or prosecutions will
not materially adversely affect the Company's business, operating results and
financial condition. Irrespective of the validity or the successful assertion
of such claims, the Company would incur significant costs and diversion of
management time and resources with respect to the defense thereof, which could
have a material adverse effect on the Company's business, operating results
and financial condition. If any claims or actions are asserted against the
Company, the Company may seek to obtain a license under a third party's
intellectual property rights. There can be no assurance, however, that under
such circumstances a license would be available on commercially reasonable
terms, or at all. See "Business--Intellectual Property."
   
  Ability of TCI to Transfer Control of the Company. The Stockholders'
Agreement provides that no Principal Cable Stockholder may transfer its shares
of the Company's stock until six years after the closing date of this offering
subject to certain exceptions, including, but not limited to, the right of any
Principal Cable Stockholder to make indirect transfers of up to 49.9% of its
equity ownership in the Company by transferring equity interests in the
subsidiary of the Principal Cable Stockholder that holds the shares of the
Company, transfers in connection with certain "spin off" transactions
involving a Principal Cable Stockholder and TCI's right to sell its
controlling interest in the Company to a third party. If TCI were to propose
such a control sale, the Stockholders' Agreement grants to Comcast, Cox and
KPCB certain "tag along" rights to participate in such a control sale, and
provides TCI with certain "drag along" rights to cause Comcast, Cox and KPCB
to sell their shares in such a control sale. The purchasers of Series A Common
Stock in this offering will not be subject to these tag along and drag along
provisions and therefore would not be entitled to participate in such a
control sale unless it involved a sale of the entire Company such as through a
merger. In addition, the Company has elected not to be subject to Section 203
of the Delaware General Corporation Law, which would otherwise provide certain
restrictions on "business combinations" between the Company and any person
acquiring a significant (15% or greater) interest in the Company other than in
a transaction approved by the Board and in certain cases by the stockholders
of the Company. Accordingly, majority control of the Company could be
transferred with no assurance that stockholders other than the Principal Cable
Stockholders and KPCB would be given the opportunity to participate in the
transaction or to receive the same amount and type of consideration for their
stock in the Company. In addition, TCI's control of the voting stock of the
Company may make the Company     
 
                                      19
<PAGE>
 
less attractive as a target for a takeover than it otherwise might be or
render more difficult or discourage a merger proposal, a tender offer or a
proxy contest, even if such actions were favored by the holders of Series A
Common Stock. See "Certain Transactions" and "Description of Capital Stock."
   
  Certain Anti-Takeover Provisions. Upon completion of this offering, the
Board will have the authority to issue up to 9,650,000 shares of Preferred
Stock and to determine the price, rights, preferences, privileges and
restrictions, including voting rights, of those shares without any further
vote or action by the stockholders. The rights of the holders of Common Stock
will be subject to, and may be adversely affected by, the rights of the
holders of any Preferred Stock that may be issued in the future. The issuance
of Preferred Stock, while providing flexibility in connection with possible
financings or acquisitions or other corporate purposes, may have the effect of
delaying, deferring or preventing a change in control of the Company, may
discourage bids for the Company's Series A Common Stock at a premium over the
market price of the Series A Common Stock and may adversely affect the market
price of, and the voting and other rights of the holders of, the Common Stock.
Such provisions may also have the effect of preventing or deterring changes in
the control or management of the Company. The Company has no current plans to
issue shares of Preferred Stock. The Company's Certificate of Incorporation
and indemnity agreements provide that the Company will indemnify officers and
directors against losses that they may incur in investigations and legal
proceedings resulting from their services to the Company, including services
in connection with takeover defense measures. See "Description of Capital
Stock."     
   
  Shares Eligible for Future Sale. Sales of a substantial number of shares of
Series A Common Stock in the public market following this offering could
adversely affect the prevailing market price of the Company's Series A Common
Stock. Following expiration of or earlier release from the 180-day lockup
agreements with Morgan Stanley & Co. Incorporated, approximately 103,803,587
shares will become eligible for sale, subject in most cases to compliance with
certain volume limitations under Rule 144 and to certain contractual
restrictions under the Stockholders' Agreement. The remaining 6,000,000 shares
held by existing stockholders will become eligible for sale on April 11, 1998.
In addition, the Company intends to register on Form S-8, immediately
following the effective date of this offering, a total of 1,052,423 shares of
Series A Common Stock reserved for issuance under the Company's Purchase Plan
and 1997 Equity Incentive Plan and a total of 1,413,000 shares subject to
outstanding options granted under the 1996 Plans. The holders of approximately
96,452,260 shares of Common Stock, and holders of warrants to purchase a total
of 2,200,000 shares of Series A Common Stock, will also be entitled to certain
rights with respect to registration of such shares of Common Stock for offer
or sale to the public. If such holders, by exercising their registration
rights, cause a large number of shares to be registered and sold in the public
market, such sales could have a material adverse effect on the market price
for the Company's Common Stock. See "Management--Employee Benefit Plans,"
"Certain Transactions," "Description of Capital Stock--Registration Rights"
and "Shares Eligible for Future Sale."     
   
  Management's Broad Discretion Over Use of Proceeds of the Offering. The
Company expects to use the net proceeds of this offering, over time, for
general corporate purposes, including working capital and capital
expenditures. The Company's management will have the discretion to allocate
the net proceeds to uses that stockholders may not deem desirable. There can
be no assurance that the net proceeds can or will be invested to yield a
significant return. See "Use of Proceeds."     
 
  Requirements for Additional Capital. The Company is investing significantly
in the development of its network infrastructure and hiring new personnel
rapidly in anticipation of potential growth in its business, which is still at
a very early stage. The Company believes that the net proceeds from this
offering, together with existing cash, cash equivalents, short-term cash
investments and capital lease financing, will be sufficient to meet its
working capital and capital expenditure requirements for at least the next 18
months. However, the Company may need to raise additional funds if its
estimates of working capital and/or capital expenditure and/or lease financing
requirements change or prove inaccurate or in order for the Company to respond
to unforeseen technological or marketing hurdles or to take advantage of
unanticipated opportunities. Over the longer term, it
 
                                      20
<PAGE>
 
   
is likely that the Company will require substantial additional funds to
continue to fund the Company's infrastructure investment, product development,
marketing, sales and customer support needs. There can be no assurance that
any such funds will be available at the time or times needed, or available on
terms acceptable to the Company. If adequate funds are not available, or are
not available on acceptable terms, the Company may not be able to continue its
network implementation, to develop new products and services or otherwise to
respond to competitive pressures. Such inability could have a material adverse
effect on the Company's business, operating results and financial condition.
The Principal Cable Stockholders have the preemptive right, subject to certain
restrictions, to purchase a pro rata portion of any new securities offered by
the Company other than securities issued pursuant to a public offering,
securities issued pursuant to any incentive plan or agreement for the benefit
of the Company's employees, directors or consultants, securities issued by the
Company in connection with an acquisition, and securities issued in exchange
for interests in a joint venture or other business combination. The existence
of this right could delay or adversely affect the Company's ability to raise
required capital on a timely basis. See "Management's Discussion and Analysis
of Financial Condition and Results of Operations."     
   
  No Prior Trading Market; Possible Volatility of Stock Price. Prior to this
offering, there has been no public market for the Common Stock of the Company,
and there can be no assurance that an active trading market will develop or,
if one does develop, that it will be maintained. The initial public offering
price, which will be established by negotiations between the Company and the
representatives of the Underwriters based upon a number of factors, may not be
indicative of prices that will prevail in the trading market. See
"Underwriters" for a discussion of the factors to be considered in determining
the initial public offering price. The stock market has from time to time
experienced significant price and volume fluctuations. In addition, the market
price of the shares of the Company's Series A Common Stock, similar to the
market prices of other Internet companies, is likely to be highly volatile.
Factors such as fluctuations in the Company's operating results, announcements
of technological innovations or new products by the Company or its
competitors, regulatory actions, and general market conditions may have a
significant effect on the market price of the Company's Series A Common Stock.
       
  Immediate and Substantial Dilution. Investors participating in this offering
will incur immediate, substantial dilution in the amount of $7.03. To the
extent that options and warrants to purchase the Company's Series A Common
Stock are exercised, there may be further substantial dilution. See
"Dilution."

                                  THE COMPANY
   
  The Company is a leading provider of Internet services over the cable
television infrastructure to consumers and businesses. The Company's primary
offering, the @Home service, allows residential subscribers to connect their
personal computers via cable modems to a new high-speed network developed and
managed by the Company. This service enables subscribers to receive the "@Home
Experience," which includes Internet service over HFC cable at a peak data
transmission speed over 300 times faster than typical dial-up connections,
"always on" availability and rich multimedia programming through an intuitive
graphical user interface. The technology foundation of the @Home Experience is
the @Network, a "parallel Internet" that optimizes traffic routing, improves
security and consistency of service, and facilitates end-to-end network
management, enhancing the Company's ability to address performance bottlenecks
before they affect the user experience. The content foundation of the @Home
Experience is provided by the Company's @Media group, which aggregates
content, sells advertising to businesses and will provide premium services to
@Home subscribers. See "Business--@Network Architecture."     
   
  The Company has entered into distribution arrangements for the @Home service
with its Cable Partners, TCI, Comcast, Cox, Rogers, Shaw, Marcus and
Intermedia, whose cable systems pass approximately 44 million homes in North
America. The Company believes that approximately two million of these homes
are currently passed by upgraded two-way HFC cable and that the Cable Partners
will complete the upgrade of systems passing a majority of these homes within
five years. The Company has launched its service through TCI, Comcast, Cox and
Intermedia in portions of 13 cities and communities (of which 11 have revenue-
paying subscribers) in the United States. To expand distribution, the Company
is aggressively seeking to work with additional United States and
international cable system operators. In order to shorten time to market for
cable operators, the Company provides a turnkey solution, which includes not
only a technology platform, but also marketing, customer service, billing and
a national brand. According to Paul Kagan Associates, Inc., cable is available
to approximately 97% of the homes in the United States, and, according to
Baskerville Communications, there will be approximately 203 million homes
passed in Europe and the Asia Pacific region in the year 2000.     
   
  For businesses, @Work services provide a platform for Internet, intranet and
extranet connectivity solutions and networked business applications over both
cable infrastructure and leased digital telecommunications lines. In order to
accelerate deployment of @Work services into major metropolitan areas, the
Company has established a strategic relationship with TCG, the country's
largest competitive local exchange carrier ("CLEC") and an affiliate of TCI,
Comcast and Cox, to provide co-location facilities and local telephone
circuits for infrastructure and subscriber connectivity. By combining the
@Network's distributed architecture with cable, telephone and technology
relationships, the @Work services provide a compelling platform for nationwide
delivery of network-based business applications. The Company has developed
this platform at a low incremental cost by leveraging its existing @Network
investment. Forrester Research projects that United States business Internet
access revenues will climb from an estimated $595 million in 1996 to a
projected $10.4 billion in 2000.     
 
  The Internet has emerged as a global communications medium enabling millions
of people to share information and conduct business electronically. Much of
the potential of the Internet remains unfulfilled due to problems with its
performance and reliability. These limitations stem from its basic
architecture, which is not optimized for distribution of data-intensive
multimedia content. As a network of hundreds of interconnected, separately
administered public and commercial networks, problems with any element in the
Internet can result in performance bottlenecks slowing data transmission speed
to that of the weakest link. A variety of new technologies are being explored
to address the performance and reliability problems encountered by users of
the Internet. However, each of these new approaches focuses on increasing the
speed of transmission along the "last-mile" connection to the user, rather
than the fundamental architectural performance problems of the Internet.
   
  The Company was founded in March 1995 on the premise that the cable
infrastructure could enable the fastest, most cost-effective delivery
mechanism for residential Internet services but that the actual speed of these
services would ultimately be limited by the fundamental architecture of the
Internet. As a result, the Company assembled a team of industry experts to
develop an advanced network architecture and the custom hardware and software
products that would address these limitations. Prior to launching the @Home
service in September 1996, the Company implemented a nationwide backbone,
designed and built its Network Operations Center with 24X7 end-to-end
management capabilities, deployed regional data centers and headend equipment,
implemented an integrated customer management system including billing and
support for those operators that elect to obtain such services from the
Company, implemented a customized browser and aggregated the multimedia
content required to deliver the @Home Experience to its first subscribers.

                                USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the 8,000,000 Shares of
Series A Common Stock offered hereby are estimated to be approximately $58.5
million (approximately $67.4 million if the Underwriters' over-allotment
option is exercised in full), at an assumed initial public offering price of
$8.00 per share and after deducting estimated underwriting discounts and
commissions and estimated offering expenses. The Company intends to use the
net proceeds for general corporate purposes, including working capital and
capital expenditures. A portion of the net proceeds may also be used to
acquire or invest in complementary businesses or products or to obtain the
right to use complementary technologies. The Company has no current plans,
agreements or commitments with respect to any such acquisition or investment,
and the Company is not currently engaged in any negotiations with respect to
any such transaction. Pending such uses, the net proceeds of this offering
will be invested in short-term, interest-bearing, investment grade securities.

                                   DILUTION
   
  The pro forma net tangible book value of the Company as of March 31, 1997
was approximately $55,670,000, or $.51 per share of Common Stock. "Pro forma
net tangible book value per share" represents the amount of total tangible
assets less total liabilities, divided by the number of shares of Common Stock
then outstanding (giving pro forma effect to the gross proceeds from the sale
of 240,000 shares of the Company's Series C Preferred Stock (which were issued
on April 11, 1997), as if issued on March 31, 1997, and to the conversion of
all outstanding shares of Preferred Stock into shares of Common Stock upon the
closing of this offering). After giving effect to the sale of the 8,000,000
Shares of Series A Common Stock offered hereby (at an assumed initial public
offering price of $8.00 per Share and after deducting estimated underwriting
discounts and commissions and estimated offering expenses), the Company's pro
forma net tangible book value as of March 31, 1997 would have been
$114,190,000, or $.97 per share of Common Stock. This represents an immediate
increase in pro forma net tangible book value of $.46 per share to existing
stockholders and an immediate dilution of $7.03 per share to new public
investors. The following table illustrates this per share dilution:

    could be further dilution to new public investors. Subsequent to March 31,
    1997, the Company (i) issued warrants to purchase, commencing December 31,
    1997, 100,000 shares of its Series C Preferred Stock at a price of $200

                     MANAGEMENT'S DISCUSSION AND ANALYSIS
               OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
  The following discussion should be read in conjunction with the Consolidated
Financial Statements and Notes thereto included elsewhere in this Prospectus.
The following discussion contains forward-looking statements. The Company's
actual results may differ significantly from those projected in the forward-
looking statements. Factors that might cause future actual results to differ
materially from the Company's recent results or those projected in the
forward-looking statements include, but are not limited to, those discussed in
"Risk Factors," "Business" and below. The Company assumes no obligation to
update the forward-looking statements or such factors.
 
OVERVIEW
   
  The Company is a leading provider of Internet services to consumers and
businesses over the cable television infrastructure. The Company was founded
in March 1995 on the premise that the cable infrastructure would enable the
fastest, most cost-effective delivery mechanism for Internet services. To
overcome fundamental architectural limitations of the Internet, the Company
has been developing and deploying the @Network, a scalable, distributed
network that links its private high-speed nationwide backbone to HFC cable
systems. As of March 31, 1997, the Company has expended more than $57.7
million on capital expenditures and operating costs and expenses (including
deferred compensation) to design and build the @Network and the corporate
infrastructure necessary to support the rollout of the @Home and @Work
services. As of March 31, 1997, the Company had developed a nationwide
backbone, designed and implemented a Network Operations Center with end-to-end
management capabilities, deployed regional data centers in 12 geographic
areas, implemented an integrated customer management system including billing
and support, implemented a customized browser and aggregated the initial
multimedia content required to deliver the @Home service to subscribers.     
   
  The Company's primary offering, the @Home service, allows subscribers to
connect their personal computers via cable modems to the Company's new high-
speed "parallel Internet." The Company has agreements with seven leading North
American cable companies for the distribution of the Company's high-bandwidth
residential consumer Internet services over their cable systems. None of these
agreements, however, places an affirmative obligation on the Company's Cable
Partners to carry any of the Company's services. The @Home service is
presently offered by TCI, Comcast, Cox and Intermedia to consumers in portions
of 13 cities and communities (of which 11 have revenue-paying subscribers) in
the United States for a flat monthly fee generally ranging from $35 to $55,
which currently includes use of a cable modem, although the Company's Cable
Partners have the right to alter such fees. Under the current arrangements
with its Cable Partners in the United States, the Company receives 35% of such
monthly fees, although this percentage is subject to change by the Principal
Cable Stockholders, and receives fees for premium services. See "Risk
Factors--Dependence on Cable Partners for Distribution; Potential Conflicts of
Interest with Principal Cable Stockholders." In Canada, the Company will
receive a smaller percentage of the monthly subscription fees billed by
Rogers, Shaw and their subdistributors because Rogers and Shaw will bear the
costs of providing additional customer support, data transport, marketing and
programming for the Canadian market which are not borne by the Company's Cable
Partners in the United States. The Company anticipates that the subscriber
pricing and revenue or royalty splits with cable system operators in
international markets will differ from those prevailing in the United States
based on differences in services and content provided by the Company and the
cable system operators. As of June 18, 1997, the Company had more than 6,000
subscribers in the United States, and was in the process of converting to its
@Home service approximately 5,000 subscribers currently receiving the Wave
interactive service provided by Rogers and Shaw in Canada.     
   
  For businesses, @Work services provide a platform for Internet, intranet and
extranet connectivity solutions and networked business applications over both
cable infrastructure and leased digital telecommunications lines. In order to
accelerate deployment of @Work services into major metropolitan areas, the
Company has established a strategic relationship with TCG, the country's
largest competitive local exchange carrier (CLEC),     
 
                                      27
<PAGE>
 
   
to provide co-location facilities and local telephone circuits for
infrastructure and subscriber connectivity. The @Work Internet service is
currently available in five metropolitan markets: Chicago, Hartford, San
Diego, the San Francisco Bay Area and Seattle. The @Work Internet service
offers dedicated high-speed Internet access options, which are priced
competitively to existing alternatives. The Company currently receives 100% of
installation and monthly access fees for these services. Businesses that are
passed by two-way HFC cable capable of delivering the @Home service also can
connect to the @Work Internet service. Under the revenue and cost arrangements
currently contemplated with its U.S. Cable Partners for such HFC connectivity,
the Company's revenue generally will depend on the services provided by the
respective parties. As of June 18, 1997, the Company was receiving revenues
from 20 business customers and had agreements with more than 130 additional
business customers to begin to install service. Substantially all of these
agreements are for services over telecommunications lines.     
 
  The Company expects to generate substantially all of its revenues through
1998 from monthly fees from subscribers to the @Home service and the @Work
Internet service and from customer services provided to the Cable Partners.
The Company believes that a growing subscriber base will generate @Media
division advertising revenues, as well as revenues from premium services and
transaction processing.
 
  The Company has incurred substantial net losses in each fiscal period since
its inception and, as of March 31, 1997, had an accumulated deficit of $38.2
million (including deferred compensation). The Company currently intends to
increase its capital expenditures and marketing and sales expenditures in
order to expand its network to support additional expected subscribers in
existing and future markets and to provide the Company's services to a growing
number of potential subscribers. As a result, the Company expects to incur
additional substantial net losses for the foreseeable future. The Company is
in the early stages of executing its business model, and the profit potential
of the Company's subscription-based business model is unproven in the Internet
industry. Because its success is dependent on the growth of the Internet into
a mass market, the Company must, among other things, develop and market
products and services that are widely accepted by consumers and businesses at
prices that will yield a profit. There can be no assurance that the Company's
services will achieve broad consumer or commercial acceptance. See "Risk
Factors--Short Operating History; History of Losses; Unproven Business Model;
No Assurance of Profitability."
   
  The Company's ability to generate future revenues will be dependent on a
number of factors, many of which are beyond the Company's control, including,
among others, the rate at which its Cable Partners upgrade their cable
infrastructures, the success of the Affiliated LCOs in marketing the @Home
service to subscribers in their local cable areas and the prices that the
Affiliated LCOs set for the @Home service. Because of the foregoing factors,
among others, the Company is unable to forecast its revenues with any degree
of accuracy. The Company currently expects to incur capital expenditures of
$30.0 million during the period from April 1, 1997 to December 31, 1997 in
order to expand its network and operating infrastructure. In addition, the
Company intends to incur significant expenses in the areas of operation and
customer services to support additional expected subscribers in current and
future markets and to market and provide the Company's services to a growing
number of potential subscribers. To the extent that such expenses are not
accompanied or followed by increased revenues, the Company's business,
operating results and financial condition will be materially adversely
affected. Accordingly, there can also be no assurance that the Company will
ever achieve profitability. See "Risk Factors" and "--Liquidity and Capital
Resources."

  REVENUES
 
  Revenues consist of monthly subscription fees and fees for customer support
activities for cable system operators, both of which are recognized during the
period in which services are provided. The Company began recognizing revenues
in September 1996. Total revenues were $676,000 and $806,000 for the year
ended December 31, 1996 and the quarter ended March 31, 1997, respectively.
Substantially all of the revenues to date have been derived from customer
services provided to TCI and Comcast. Revenues from related parties (the
Principal Cable Stockholders) represented 94% of revenues for the year ended
December 31, 1996 and 86% of revenues in the three months ended March 31,
1997.
 
  COSTS AND EXPENSES
   
  Quarterly expenses for the Company increased sequentially during 1995, 1996
and the first quarter of 1997 as a result of increased business activities,
initially related to development activities and the build-out and testing of
the @Network and more recently attributable to subscriber growth for the @Home
service commencing in the third quarter of 1996. As the @Home service has been
initiated in additional geographic areas, increases in marketing and customer
service activities, increased personnel and the additional support of the
@Network have contributed to increases in expenses. The Company believes
continued expansion of operations as well as its network infrastructure is
critical to the achievement of its goals and anticipates that costs and
expenses will continue to increase in each quarter for the foreseeable future.
       
  Operating Costs. Operating costs are primarily related to providing services
to customers and maintaining the @Network infrastructure. These costs include
salaries and related expenses for operating and customer service personnel,
telecommunications transport costs, content programming and the depreciation,
amortization and maintenance of capital equipment. As a development stage
company with no revenues, there were no operating costs during 1995. For the
year ended December 31, 1996, operating costs were $7.0 million, primarily as
a result of activities associated with network and customer service start-up.
Operating costs for the four     
 
                                      29
<PAGE>
 
   
quarters of 1996 and the first quarter of 1997 were $679,000, $1.1 million,
$2.0 million, $3.2 million and $4.3 million, respectively. Increases in the
second and third quarters of 1996 were primarily attributable to increased
expenditures to establish the Company's customer operations department as well
as the development of additional content programming resources. Increases in
the fourth quarter of 1996 and the first quarter of 1997 were principally
attributable to additional transport costs to support the rollout of the
@Network to additional sites, maintenance and depreciation of capital
equipment, increased customer operations expenditures to support the
subscriber base and additional expenses for content programming.     
   
  Product Development and Engineering. Product development and engineering
expenses consist primarily of salaries and related expenses for personnel,
fees to outside contractors and consultants, the allocated cost of facilities,
and the depreciation and amortization of capital equipment. Product
development and engineering expenses increased from $1.4 million for the
period from March 28, 1995 (inception) to December 31, 1995 (the "Inception
Period") to $6.3 million for the year ended December 31, 1996 as a result of
additional personnel costs to support the expansion, development and testing
of the @Network. Product development and engineering expenses for the four
quarters of 1996 and the first quarter of 1997 were $1.3 million, $1.5
million, $1.9 million, $1.6 million and $2.3 million, respectively. The
sequential increase in expenses for the first three quarters of 1996 was due
primarily to additional personnel costs to support the expansion, development
and testing of the @Network. The decrease in expenses in the fourth quarter of
1996 from the previous quarter was due to a reduction in certain royalty
payments. The increase in expenses in the first quarter of 1997 over the
fourth quarter of 1996 is principally attributable to the increase in
personnel and related expenses. Product development and engineering expenses
are primarily due to three areas: the design, testing and deployment of the
@Network, the development of software tools and enabling platforms for the
creation and distribution of enhanced content and applications specifically
designed to take advantage of the @Network and the development of @Work
services. Product development and engineering costs have been expensed as
incurred.     
   
  Sales and Marketing. Sales and marketing expenses consist primarily of
salaries, commissions and promotional expenses. Sales and marketing expenses
increased from $496,000 for the Inception Period to $6.4 million for the year
ended December 31, 1996 as a result of increased sales and marketing
activities to support the expansion of regional deployments of the @Home and
@Work services. Sales and marketing expenses for the four quarters of 1996 and
the first quarter of 1997 were $831,000, $1.3 million, $1.9 million, $2.4
million and $2.9 million, respectively. The sequential increase in expenses
was the result of continued increases in sales and marketing activities to
support the expansion of regional deployments of the @Home and @Work services.
Sales and marketing expenses have increased primarily due to the expansion of
the Company's sales force, related travel and entertainment expenses,
expenditures for trade shows and increased marketing activities to attract
additional cable partners, subscribers and corporate accounts. The Company and
the Cable Partners both market the Company's services to prospective customers
and determine the specific costs and expenses to be borne by each party. The
Company bears the cost of national sales and marketing programs (such as
public relations, distribution, database marketing and acquisition programs);
retail distribution; joint Company/Cable Partner market research; and
retention and loyalty programs. Expenditures typically borne by the Cable
Partners include local sales and marketing programs such as public relations,
events and acquisition programs; demonstration sites; market specific
research; and cross-cable services database marketing and bundling with core
cable programs.     
   
  General and Administrative. General and administrative expenses consist
primarily of administrative and executive personnel costs, fees for
professional services and the costs of in-house systems and infrastructure to
support the operations of the Company. General and administrative expenses
increased from $943,000 for the Inception Period to $6.1 million for the year
ended December 31, 1996 as a result of additions of personnel to support the
operations of the Company and their related costs. General and administrative
expenses for the four quarters of 1996 and the first quarter of 1997 were
$998,000, $737,000, $1.9 million, $2.5 million and $2.2 million, respectively.
The quarterly increases beginning with the second quarter of 1996 were
primarily related to additions of personnel to support the operations of the
Company and their related costs. The increase in general and administrative
expenses in the third and fourth quarters of 1996 relates primarily to stock
compensation charges resulting from stock options and restricted stock
purchase agreements.     
 
                                      30

  INTEREST INCOME, NET
 
  Interest income, net was $84,000, $79,000, $212,000, $139,000 and $40,000
for the four quarters of 1996 and the first quarter of 1997, respectively.
Interest income, net was $130,000 and $514,000 for the Inception Period and
the year ended December 31, 1996, respectively. Interest income, net
represents interest earned by the Company on its cash and short-term cash
investments, less interest expense on capital lease obligations.
 
  INCOME TAXES
   
  At December 31, 1996, the Company had net operating loss and research and
development tax credit carryforwards for federal and state tax purposes of
$16.0 million and $120,000, respectively, which will expire at various times
through the year 2011 if not utilized. Certain changes in the ownership of the
Company, as defined in the Tax Reform Act of 1986 and similar state
provisions, may restrict the utilization of such carryforwards. The proposed
issuance of Series A Common Stock in this offering would not result in such a
change in ownership. At December 31, 1996, the Company had net deferred tax
assets of $11.0 million relating principally to the net operating loss and
research and development credit carryforwards. Realization of deferred tax
assets is dependent on future earnings, if any, the timing and amount of which
are uncertain. A valuation allowance has been recorded for the entire net
deferred tax asset as a result of uncertainties regarding the realization of
the asset due to the lack of earnings history of the Company. Accordingly, the
Company has not recorded any income tax benefit for net losses incurred for
any period from inception through March 31, 1997. See Note 6 of Notes to
Consolidated Financial Statements.     
 
  NET LOSS
   
  The net loss for 1996 was $24.5 million, an increase from $2.8 million for
the Inception Period. The Company's net loss was $3.7 million, $4.6 million,
$7.2 million, $9.0 million and $10.9 million for the four quarters of 1996 and
the first quarter of 1997.  The increase in loss was due primarily to
increases in expenses as a result of increased business activities.     
 
FACTORS AFFECTING OPERATING RESULTS
 
  The Company's revenue is difficult to forecast in part because the market
for high-bandwidth Internet service is rapidly evolving. The Company's
quarterly operating results may fluctuate significantly in the future as a
result of a variety of factors, many of which are outside the Company's
control. Factors that may affect the Company's quarterly operating results
attributable to its @Home service include the timing of Cable Partners'
upgrades of their cable infrastructures and rollouts of the @Home service, the
rate at which customers subscribe to the Company's Internet services and the
prices subscribers pay for such services, subscriber churn rates, changes in
the revenue splits between the Company and the Cable Partners, the demand for
Internet advertising, the effectiveness of Affiliated LCOs' marketing and
other operations, and potential competition with Affiliated LCOs for
advertising revenue. Quarterly operating results attributable to the Company's
@Work services are dependent on the demand for, and level of acceptance of,
the Company's corporate Internet, intranet and extranet connectivity and
telecommuting solutions, the introduction of, demand for, and level of
acceptance of, the Company's value-added business applications and the timing
of Cable Partners' upgrades of their cable infrastructures and rollouts of the
@Home service. Additional factors that may affect the Company's quarterly
operating results generally include the amount and timing of capital
expenditures and other costs relating to the expansion of the Company's
network, the introduction of new Internet and telecommuting services by the
Company or its competitors, price competition or pricing changes in the
Internet, cable and telecommunications industries, technical difficulties or
network downtime, general economic conditions and economic conditions specific
to the Internet, corporate intranet and cable industries. The Company operates
with very little backlog, and quarterly sales and operating results are
difficult to forecast even in the short term. There can be delays in the
commencement and recognition of revenue because the installation of
telecommunication lines to implement certain services have lead times that are
controlled by third parties. A significant portion of the Company's expenses
are fixed in advance based in large part on future revenue forecasts. If
revenue is below expectations in
 
                                      31
<PAGE>
 
any given quarter, the adverse impact of the shortfall on the Company's
operating results may be magnified by the Company's inability to adjust
spending to compensate for the shortfall. Therefore, a shortfall in actual as
compared to estimated revenue would have an immediate adverse effect on the
Company's business, financial condition and operating results that could be
material. In addition, the Company plans to increase operating expenses to
fund additional research and development, sales and marketing, general and
administrative activities and infrastructure. To the extent that these
expenses are not accompanied by an increase in revenues, the Company's
business, operating results and financial condition could be materially
adversely affected. Due to all of the foregoing factors, it is likely that the
Company's operating results in one or more future quarters will fail to meet
or exceed the expectations of securities analysts or investors. In such event,
the trading price of the Series A Common Stock would likely be materially
adversely affected.
 
LIQUIDITY AND CAPITAL RESOURCES
 
  Since inception, the Company has financed its operations primarily through a
combination of private sales of equity securities and capital equipment
leases. At March 31, 1997, the principal source of liquidity for the Company
was $6.4 million of cash, cash equivalents and short-term cash investments. In
April 1997, the Company raised approximately $48.0 million, less issuance
costs, from the sale of convertible preferred stock. The Company finances and
expects to continue financing its substantial capital equipment expenditures
from a variety of sources including direct vendor leasing programs and third
party commercial leasing arrangements.
 
  The Company has had significant negative cash flows from operating
activities in each quarterly period to date. Cash used in operating activities
for the Inception period, the year ended December 31, 1996 and the quarter
ended March 31, 1997 was $2.1 million, $19.3 million and $8.3 million,
respectively. Cash used in operating activities in each of these periods was
primarily the result of net losses.
   
  Cash used in investing activities for the Inception period and for the year
ended December 31, 1996 was $1.0 million and $14.3 million, respectively. Cash
used for investing activities in these periods was primarily the result of
capital expenditures for equipment, software, furniture and fixtures as well
as purchases of net short-term cash investments. For the quarter ended March
31, 1997, cash provided by investing activities was $3.4 million, resulting
primarily from sales and maturities of short-term cash investments, partially
offset by capital expenditures. Gross capital expenditures for equipment,
software, furniture and fixtures in the Inception period, the year ended
December 31, 1996 and the quarter ended March 31, 1997 were $963,000, $15.2
million and $4.5 million, respectively, of which $0, $7.9 million and $3.1
million, respectively, were financed through capital leases. The Company
expects to expend a minimum of $30.0 million in leasehold improvements,
equipment, software and fixtures from April 1, 1997 to December 31, 1997, much
of which will be financed through capital leases.     
 
  Cash provided by financing activities for the Inception period and the year
ended December 31, 1996, was $10.0 million and $36.5 million, respectively,
resulting primarily from net proceeds from the sale of Preferred Stock. Cash
used in financing activities for the quarter ended March 31, 1997 was $688,000
resulting primarily from payments on capital lease obligations.
 
  The Company believes that the net proceeds from this offering, together with
existing cash, cash equivalents, short-term cash investments and capital lease
financing, will be sufficient to meet its working capital and capital
expenditure requirements for at least the next 18 months. Thereafter, if cash
generated by operations is insufficient to satisfy the Company's liquidity
requirements, the Company may need to sell additional equity or debt
securities or obtain additional credit facilities. The sale of additional
equity or convertible debt securities may result in additional dilution to the
Company's stockholders. There can be no assurance that the Company will be
able to raise any such capital on terms acceptable to the Company or at all.

                                   BUSINESS
   
  The Company is a leading provider of Internet services over the cable
television infrastructure to consumers and businesses. The Company's primary
offering, the @Home service, allows residential subscribers to connect their
personal computers via cable modems to a new high-speed network developed and
managed by the Company. This service enables subscribers to receive the "@Home
Experience," which includes Internet service over HFC cable at a peak data
transmission speed over 300 times faster than typical dial-up connections,
"always on" availability and rich multimedia programming through an intuitive
graphical user interface. The technology foundation of the @Home Experience is
the "@Network," a "parallel Internet" that optimizes traffic routing, improves
security and consistency of service, and facilitates end-to-end network
management, enhancing the Company's ability to address performance bottlenecks
before they affect the user experience. The content foundation of the @Home
Experience is provided by the Company's @Media group, which aggregates
content, sells advertising to businesses and will provide premium services to
@Home subscribers.     
   
  The Company has entered into distribution arrangements for the @Home service
with its Cable Partners, TCI, Comcast, Cox, Rogers, Shaw, Marcus and
Intermedia, whose cable systems pass approximately 44 million homes in North
America. The Company believes that approximately two million of these homes
are currently passed by upgraded two-way HFC cable and that the Cable Partners
will complete the upgrade of systems passing a majority of these homes within
five years. The Company has launched its service through TCI, Comcast, Cox and
Intermedia in portions of 13 cities and communities (of which 11 have revenue-
paying subscribers) in the United States. To expand distribution, the Company
is aggressively seeking to work with additional United States and
international cable system operators. In order to shorten time to market for
cable operators, the Company provides a turnkey solution, which includes not
only a technology platform, but also marketing, customer service, billing and
a national brand. According to Paul Kagan Associates, Inc., cable is available
to approximately 97% of the homes in the United States, and, according to
Baskerville Communications, there will be approximately 203 million homes
passed in Europe and the Asia Pacific region in the year 2000. Forrester
Research estimates that United States consumers spent more than $620 million
for Internet access in 1996 and projects that such expenditures will grow to
more than $15 billion in 2001.     
   
  For businesses, @Work services provide a platform for Internet, intranet and
extranet connectivity solutions and networked business applications over both
cable infrastructure and leased digital telecommunications lines. In order to
accelerate deployment of the @Work services into major metropolitan areas, the
Company has established a strategic relationship with TCG, the country's
largest competitive local exchange carrier, to provide co-location facilities
and local telephone circuits for infrastructure and subscriber connectivity.
By combining the @Network's distributed architecture with cable, telephone and
technology relationships, the @Work services provide a compelling platform for
nationwide delivery of network-based business applications. The Company has
developed this platform at a low incremental cost by leveraging its existing
@Network investment.  Forrester Research projects that United States
commercial Internet access revenues will climb from an estimated $595 million
in 1996 to a projected $10.4 billion in 2000.     
   
  The Company was founded in March 1995 on the premise that the cable
infrastructure could enable the fastest, most cost-effective delivery
mechanism for residential Internet services but that the actual speed of these
services would ultimately be limited by the fundamental architecture of the
Internet. As a result, the Company assembled a team of industry experts to
develop an advanced network architecture and the custom hardware and software
products that would address these limitations. Prior to launching the @Home
service in September 1996, the Company implemented a nationwide backbone,
designed and built its Network Operations Center with 24X7 end-to-end
management capabilities, deployed regional data centers and headend equipment,
implemented an integrated customer management system including billing and
support for those operators that elect to obtain such services from the
Company, implemented a customized browser and aggregated the multimedia
content required to deliver the @Home Experience to its first subscribers.

INDUSTRY BACKGROUND
 
  GROWTH OF INTERNET USAGE AND CONTENT
   
  The Internet, a network of hundreds of interconnected, separately-
administered public and commercial networks, has emerged as a global
communications medium enabling millions of people to share information and
conduct business electronically. During the past few years, the number of
Internet users, advertisers and content developers and businesses online has
grown dramatically. With readily-available, low-cost Internet access,
consumers and businesses are making increased use of Web browsers, electronic
mail, corporate intranets, telecommuting, online advertising and electronic
commerce. According to Jupiter Communications, the number of Internet
households worldwide will grow from an estimated 23.4 million in 1996 to 66.6
million by 2000. The Company believes that this growth in the number of users
will drive more substantial increases in both Internet advertising, which
International Data Corporation ("IDC") estimates will grow from $181 million
in 1996 to $2.9 billion in 2000, and Internet commerce, which IDC estimates
will grow from $318 million in 1995 to $95 billion in 2000.     
   
  Internet usage continues to be stimulated by a number of factors, including
the emergence of the World Wide Web, the increasing sophistication of Internet
browsers and Web-enabled software, the availability of low-cost, flat-rate
pricing for Internet access and online services, and the wealth of
increasingly useful information published on the Internet. Increased Internet
usage and the availability of powerful new tools for the development and
distribution of Internet content have led to a proliferation of Internet-based
services, such as advertising, online magazines, specialized news feeds,
interactive games and educational and entertainment applications, that are
increasingly incorporating multimedia information such as video and near-CD-
quality audio clips. The Internet has the potential to become a platform
through which consumers and businesses easily access rich multimedia
information and entertainment, creating new sources of revenue for
advertisers, content providers and businesses. The growth of Internet
advertising and commerce depends, in part, on the ability of advertisers and
online merchants to deliver a compelling multimedia message to attract viewers
and potential customers. However, multimedia content and other data-intensive
applications require high bandwidth.     
 
  LIMITATIONS OF INTERNET ARCHITECTURE AND BANDWIDTH
   
  The potential of the Internet as a medium for communication, education,
entertainment and commerce remains unfulfilled due to problems with its
performance and reliability. The Internet's performance limitations stem from
its basic architecture, which is not optimized for distribution of data-
intensive multimedia content. A limitation associated with any element in the
system, whether it is the "last-mile" connection to the user (the "local
loop"), the infrastructure of the ISP or OSP, the Internet backbone or the
content provider's Web server, can result in performance bottlenecks that slow
data transmission speed to that of the weakest link. For example, the Internet
frequently becomes overloaded when transmitting the same data streams from
popular Web site servers to millions of individual users. In addition, dial-up
users frequently encounter busy signals upon attempting to connect to their
ISP/OSPs and are unable to access quality multimedia content readily due to
the slow speed of their analog modems. Because the Internet is an
interconnection of independently operated networks, there is no single point
of accountability or management to respond to performance problems or to
ensure optimized Internet traffic routing, security or consistency of service.
Therefore, no single ISP/OSP offers an end-to-end solution to Internet
bottlenecks. Performance limitations of the Internet frustrate and discourage
users from fully utilizing it as a convenient and effective information tool,
a compelling educational and entertainment resource, or a way to purchase
goods and services.     
 
  TECHNOLOGIES TO INCREASE INTERNET BANDWIDTH
 
  Several new technologies attempt to address the performance problems of the
Internet. While these technologies increase the transmission speed of data
across the local loop, they do not provide an end-to-end solution to the
fundamental performance constraints inherent in the Internet architecture.
 
 
                                      34
<PAGE>
 
   
  Improved Modem Offerings. In early 1997, dial-up modems offering a peak data
transmission speed of 56 Kbps were introduced for use with ISP/OSPs over
existing telephone lines, although many ISP/OSPs do not yet support this
transmission speed. The lack of a universal standard has slowed the rate of
adoption of faster modems.     
   
  Telecommunications-Based Offerings. Integrated Services Digital Network
("ISDN") technology enables a peak data transmission speed of 128 Kbps between
the user and the ISP/OSP over specially conditioned telephone lines. Although
ISDN technology has been available for several years, it has not been widely
deployed due primarily to its high costs. Asymmetric Digital Subscriber Line
("ADSL") is currently the most prominent implementation of Digital Subscriber
Line ("xDSL") technology, an emerging telecommunications protocol originally
developed to deliver video on demand. ADSL enables peak data transmission
speeds of 8.4 Mbps downstream from the ISP/OSP to the user and 640 Kbps
upstream from the user to the ISP/OSP; however, typical implementations
realize substantially lower data transmission speeds. ADSL access is priced
significantly above other access services and is not expected to be widely
available in the near term.     
   
  Wireless Offerings. Satellite-delivered approaches such as direct broadcast
satellite ("DBS") currently provide a peak data transmission speed of
approximately 400 Kbps downstream and rely on dial-up modems and the telephony
network for upstream transmission ("telephone return"). These approaches have
scaling limitations due to the necessity of dividing a finite amount of
satellite bandwidth among subscribers in a broad geographic area. Other
wireless offerings rely on ground-based radios instead of satellites. Such
offerings include multichannel multipoint distribution service ("MMDS") and
local multipoint distribution service ("LMDS"), which are one-way and two-way
high-bandwidth wireless digital broadcasting systems, respectively. MMDS and
LMDS are not yet widely available, require unobstructed "line-of-sight"
transmission paths and may require additional radio frequency spectrum
allocations, an entirely new distribution infrastructure and new equipment
(including specialized radio modems).     
   
  Cable Offerings. In recent years, the Company believes most large cable
system operators have begun upgrading to HFC cable infrastructure both to
compete more effectively with DBS television providers, which offer a large
number of television channels with digital audio and video, and to increase
revenue by offering digital television, telephony and data transmission using
cable modems through the upgraded infrastructure. Like corporate LANs, the
cable infrastructure is "always on" and does not consume network resources
when idle, making it well-suited for Internet data transmission. This
architecture contrasts with a switched telephone system, which requires a
separate completed circuit for each data transmission session. Peak data
transmission speeds across HFC cable approach 27 Mbps downstream and 10 Mbps
upstream. Modern HFC networks are highly scalable because HFC cable can
transmit multiple independent data streams over the fiber optic distribution
system that links a single headend (a cable distribution center) to several
neighborhoods in a metropolitan area.     
 
THE COMPANY'S OPPORTUNITY
   
  The Company believes that the rich, multimedia promise of the Internet can
be delivered to businesses and consumers through the global deployment of a
new network architecture that exploits the performance advantages and "always
on" characteristic of the two-way HFC cable infrastructure. Such an
architecture would significantly enhance the user's experience by enabling and
encouraging the creation and aggregation of compelling, multimedia content
that is optimized for a high-bandwidth environment. The Company also believes
that this network architecture could be leveraged to extend high-speed
Internet access to businesses, deliver value-added applications and provide
remote access to corporate LANs. For cable system operators, the Company
believes a turnkey data transmission solution that provides the data network
design capability and other engineering resources required to address the
complex problems associated with delivering high-speed Internet services over
cable would have strong appeal.

THE COMPANY'S SOLUTION
   
  The Company is a leading provider of Internet services to consumers and
businesses over cable infrastructure. The Company has entered into
distribution arrangements for the @Home service with TCI, Comcast, Cox,
Rogers, Shaw, Marcus and Intermedia, whose cable systems pass approximately 44
million homes in North America. The Company believes that approximately two
million of these homes are currently passed by upgraded two-way HFC cable and
that the Cable Partners will complete the upgrade of systems passing a
majority of these homes within five years. The Company's two Internet
services, @Home for consumers and @Work for businesses, provide an end-to-end
solution over the Company's new network architecture (the "@Network"), which
is a high-performance "parallel Internet" for high-bandwidth data transmission
and content. The @Network leverages the cable infrastructure and other high-
speed local-loop technologies, alleviates the bottlenecks inherent in the
architecture of the Internet and serves as a platform for a variety of high-
bandwidth interactive services. The @Home service combines the technological
and programming capabilities of the Company to provide the comprehensive
"@Home Experience." The @Home Experience includes the fastest residential
Internet access currently available (over 300 times faster when using HFC
cable than a 28.8 Kbps modem) and is "always on" (eliminating the tedious and
unreliable dial-up process). The Company's @Media programming services
aggregate high-quality and compelling multimedia content, stimulate the
development of new high-bandwidth content and deliver this content through an
intuitive graphical user interface. The @Work services offer secure and
reliable Internet access through connections between corporate LANs and the
@Network, and the ability to create virtual private networks. In addition to
providing programming services for the @Home Experience, the Company's @Media
group sells advertising and will package premium services. The Company's
comprehensive customer and technical service organization supports all of its
services on a 24X7 basis. The Company expects that many of its services will
be highly transferable to international markets, recognizing that some degree
of localization of content will be essential to achieving success.     
 
  The @Network is a scalable, distributed, intelligent network architecture
that combines a private high-speed nationwide backbone with distributed
caching. Caching moves frequently accessed information close to the user to
avoid multiple transmissions of the same data over the backbone. The @Network
is an end-to-end network solution, enabling the Company to manage the network
24 hours a day from a central Network Operations Center ("NOC") and enhancing
its ability to address performance bottlenecks before they affect the user
experience. All elements of the @Network are readily scalable, enabling it to
provide sustainable high performance as usage increases. In order to shorten
time to market for cable operators, the Company provides a turnkey solution,
which includes not only a technology platform, but also a national brand,
marketing, customer service and billing. This solution enables cable operators
to leverage their infrastructures to deliver high-bandwidth, interactive data
services that represent significant new revenue opportunities.
 
STRATEGY
 
  The Company's objective is to leverage the cable infrastructure and other
high-speed, local loop transmission technologies to become the leading global
provider of branded, high-speed Internet services. The Company's strategy to
achieve this objective has the following key elements:
   
  Expand Distribution. The Company has strategic relationships with seven
leading cable companies whose cable systems pass approximately 44 million
homes. To expand distribution, the Company aggressively seeks to form
strategic relationships with additional United States and international cable
companies to obtain exclusive rights to their coverage areas. In addition, the
Company has developed a comprehensive set of step-by-step plans and
certification processes to verify that cable companies have upgraded their
cable systems to a two-way HFC cable infrastructure that is capable of
delivering the Company's services. With these plans and processes, TCI,
Comcast, Cox and Intermedia have launched the @Home service in portions of 13
cities and communities (of which 11 have revenue-paying subscribers) in the
United States. The Company plans to continue to roll out the @Home service as
cable system operators complete two-way HFC upgrades. In addition, to access
residences that are not upgraded to two-way HFC cable, the Company is
exploring alternative delivery mechanisms, such     
 
                                      36
<PAGE>
 
as the use of one-way HFC cable with telephone return and the use of high-
speed telecommunications services for multiple dwelling units ("MDUs").
 
  Drive Penetration by Providing the Most Compelling Internet Experience. The
Company strives to provide the most compelling interactive Internet experience
available to drive subscriber penetration. The @Home service enables the @Home
Experience, which includes the fastest residential Internet access currently
available, is "always on" and aggregates high-quality and compelling
multimedia Internet content, including video clips and near-CD-quality sound,
with an intuitive graphical user interface. The Company is working with
leading advertisers and over 100 content providers to develop multimedia
content that takes advantage of the high bandwidth and caching and
multicasting capabilities of the @Network to provide an enriched interactive
experience for the user. For international markets, the Company intends to
rely on local cable system operators and content providers to develop high-
quality localized content that delivers the @Home Experience abroad. The
Company manages the @Network from end to end, 24 hours a day, enhancing its
ability to address performance bottlenecks before they affect the user
experience. The Company and the Cable Partners have developed a comprehensive
approach for managing all subscriber interactions, including installation,
billing and transaction management, technical support and customer service,
intended to ensure that every customer interaction with the @Home service is a
positive experience.
 
  Build Brand Awareness. The Company's marketing strategy is to accelerate
penetration within its geographic markets by creating awareness for the
"@Home" brand to make it synonymous with a compelling online interactive
multimedia experience. The Company supports this strategy through cooperative
promotional programs with the Cable Partners, which are licensed by the
Company to use the "@Home" brand in conjunction with their own brands in the
distribution of the Company's services, and through certification of third-
party hardware and software products as "@Home Ready."
 
  Maintain Technological Leadership. The Company's technology strategy is to
continue to develop advanced technological solutions that maximize the
inherent advantages of "always on" connectivity, speed, security and
reliability afforded by the cable infrastructure and the @Network. The Company
continually works to develop: new caching and replicating techniques to
improve the performance and efficiency of the @Network; advanced multicasting
technologies to provide efficient transport of "one-to-many" content;
adaptations of the Company's services for use over non-HFC access
technologies; advertisement targeting and content personalization systems to
fit desired subscriber profiles; virtual private network technology solutions
to enable secure and scalable end-to-end telecommuting and commercial services
over the @Network; and other services and technologies designed to enhance the
@Home Experience and improve market penetration.
   
  Offer Unique Value Proposition to Business Subscribers. The Company's
strategy for its @Work services is to provide secure, reliable corporate
Internet, intranet and extranet connectivity solutions complemented by a
series of network-based business applications. By combining @Network's
distributed architecture with cable, telephone and technology relationships,
the @Work services provide a compelling platform for nationwide delivery of
network-based business applications. The Company has developed this platform
at a low incremental cost by leveraging its existing @Network investment. For
example, by connecting distant workers to the corporate LAN in areas where the
@Home service is available, the Company believes the @Work services can offer
a fast, secure and cost-effective solution for telecommuters. The @Work
services will also facilitate corporate broadcasting to the desktop, and
distributed applications and Web hosting. The Company intends to expand its
network reach by leveraging its relationships with TCG (the nation's largest
CLEC), cable system operators, other high-speed facility providers and
technology suppliers to reach commercial subscribers across the nation. The
Company intends to create awareness of the "@Work" brand, making it synonomous
with network-based distributed applications.     
   
  Drive Incremental Revenues from Advertising and Premium Services. The
strategy of the Company's @Media group is to leverage the high bandwidth and
comprehensive usage-compilation capabilities of the @Network to offer
advertisers and content providers a technological platform for the delivery of
rich, multimedia advertising and premium content to @Home subscribers. The
Company sells advertising that uses the @Home     
 
                                      37
<PAGE>
 
audio/video advertising window to businesses for advertising on national areas
of the @Home Guide for the @Home service. The Company also works with content
and application providers to deliver specialized content such as high-speed
online interactive games, new applications such as near-CD-quality online
music, and online transactions where subscribers can automatically purchase
and download software or music. The multimedia and technology platforms
developed with @Media technologies significantly enhance the @Home Experience.
The Company negotiates revenue sharing agreements for such advertising,
content and online transactions.
   
  While the Company retains 100% of all United States national advertising
revenue delivered on the @Home service through the Company's U.S. Cable
Partners, LCOs of the U.S. Cable Partners retain 100% of revenue generated
from local service offerings that do not require access to an Internet
backbone or that relate to programming within the designated local areas of
the home page for the @Home service, such as revenues from advertising. In
Canada, the Company will share national advertising revenue with its Canadian
Cable Partners. Moreover, given the national coverage of the combined
operations of the Principal Cable Stockholders and their Affiliated LCOs, the
Principal Cable Stockholders and their Affiliated LCOs could strike agreements
with advertisers that would effectively result in broad-based advertising
campaigns throughout most of the United States in competition with the
Company's national advertising campaigns, generating revenue only for
Affiliated LCOs and not for the Company. Accordingly, the @Home Service may
contain a significant amount of advertising that is national in scope and
focus for which it receives no share of the revenues.     
 
PRODUCTS AND SERVICES
   
  The Company currently offers two Internet services, @Home for consumers and
@Work for businesses. The Company's @Media group complements the @Home service
by providing programming, selling advertising and packaging premium services.
    
  @HOME SERVICE
   
  The Company's primary offering is the @Home service, a comprehensive
Internet solution that leverages the two-way HFC cable television
infrastructure and the Company's technological and programming capabilities to
provide the @Home Experience, which the Company believes is the most
compelling consumer Internet experience currently available. By connecting via
a cable modem to the @Network through the local cable infrastructure, @Home
subscribers' personal computers can achieve a peak data transmission speed
over two-way HFC cable of 10 Mbps (10,000 Kbps), over 300 times faster than
the peak data transmission speed of a 28.8 Kbps modem. This high bandwidth is
critical for sophisticated multimedia applications, advertising, online
commerce and online interactive games. In addition, the two-way cable
infrastructure is "always on," providing instantaneous access to the Internet
and eliminating the need for a tedious dial-up procedure using the telephone
network.     
   
  The Company's programming services, provided by the @Media group, enhance
the @Home Experience by aggregating high-quality and compelling multimedia
content available on the Internet and delivering this content through an
intuitive graphical user interface. The cornerstone of this programming is the
@Home Guide, the user's guide to the high-quality multimedia content on the
Web. The Company believes the @Home Guide broadens the appeal of online
services beyond technology enthusiasts to the mass market by simplifying
navigation, increasing the subscriber's knowledge of Internet resources,
presenting compelling high-bandwidth content with animated graphics, near-CD-
quality audio and video clips, and stimulating persistent usage by promoting
current events and interesting new services. The @Home Guide is organized
around a series of "channels," which are defined by both topical subjects
(such as news, technology, sports or popular culture) and audiences (such as
children, game players or shoppers), and which present engaging "best of the
Web" editorial content every day. With the @Home Guide, the Company generates
and directs regular audience traffic to @Media and content providers'
offerings. The @Home Guide includes @Home QuickHits, which takes advantage of
the "always on" feature of the @Home service to provide one-click access to
personal stock portfolios, local weather and traffic, dining and other useful
daily information. The @Home Experience also     
 
                                      38
<PAGE>
 
permits @Home subscribers to access online services, purchase software and
engage in multiplayer gaming and interactive shopping.
   
  The @Home service is currently offered to consumers in the United States for
flat monthly fees generally ranging from $35 to $55, including a cable modem
provided by the Cable Partner. Installation of the @Home service is provided
by the Cable Partner at a price generally ranging from $75 to $175. Upon
installation, each new subscriber's personal computer is configured for the
@Home Experience with @Home client software, which provides access to the
@Home Guide and an extensive set of online services. The @Home client software
includes a customized Netscape browser and other high-performance and
multimedia software optimized for the @Home Experience. In addition to making
the Internet considerably easier to access for consumers, this software offers
advertisers and content and application providers a rich and consistent client
environment for delivering multimedia advertising, content and applications.
       
  The @Home service is currently offered by TCI, Comcast, Cox and Intermedia
in portions of 13 cities and communities in the United States, 11 of which
have revenue-paying subscribers: Arlington Heights (IL), Baltimore (MD),
Detroit (MI), Fremont (CA), Hartford (CT), Orange County (CA), Phoenix (AZ),
San Diego (CA), Sarasota (FL), Seattle (WA) and Union County (NJ); and two of
which are in test: Nashville (TN) and Philadelphia (PA). Under the current
United States Cable Partner arrangements, the Company receives 35% of monthly
fees and fees for premium services, and the Cable Partner retains the entire
installation payment. In Canada, the Company will receive a smaller percentage
of the monthly subscription fees billed by Rogers, Shaw and their sub-
distributors because Rogers and Shaw will bear the costs of providing
additional customer support, data transport, marketing and programming for the
Canadian market, which are not borne by the Company's Cable Partners in the
United States. In international markets, the Company anticipates that the
subscriber pricing and revenue or royalty splits with cable system operators
will be different from those that prevail in the United States based on
differences in services and content provided by the international cable system
operators, data transport costs and regulatory environments. To the extent
that the Company offers terms of distribution and other services that are more
favorable than those offered to the Principal Cable Stockholders, they have
the right to obtain such more favorable terms under a "most favored nation"
provision in the Master Distribution Agreement. For areas where two-way HFC
cable is not yet available, the Company has developed a telephone return
version of the @Home service, which uses one-way HFC cable for high-speed
downstream transmission and an analog telephone line for upstream
transmission, and an MDU @Home service offering delivered via a digital
telecom-based connection for high-density apartment and condominium complexes.
To access the @Home service, subscribers need a personal computer with at
least a 66 MHz 486 or equivalent microprocessor, 16 megabytes of main memory
and the ability to support an ethernet connection. The Company is developing
software and a specialized @Home service to enable set-top boxes connected to
televisions and cable modems to deliver the @Home Experience to the broad
market that does not use computers. See "Risk Factors--Dependence on Cable
Partners for Distribution; Potential Conflicts of Interest with Principal
Cable Stockholders" and "--Control by Principal Cable Stockholders of Terms of
Distribution."     
 
  @WORK SERVICES
 
  @Work services provide a platform for corporate Internet, intranet and
extranet connectivity solutions and have the ability to provide a series of
networked business applications over both HFC cable and leased digital
telecommunications lines that leverage the @Network. In order to accelerate
deployment of @Work services into metropolitan areas, the Company has
established a strategic partnership with TCG, the country's largest CLEC, to
provide targeted co-location and local telephone circuits for infrastructure
and subscriber connectivity. The Company offers @Work Internet and plans to
offer @Work Remote services.
 
  @Work Internet. The @Work Internet service delivers dedicated, high-speed,
end-to-end managed Internet connectivity to commercial enterprises over both
local telephone circuits and HFC cable. The @Work Internet service offers
telecommunications access options at peak data transmission speeds ranging
from 56 Kbps to 45 Mbps, which are priced competitively to existing
alternatives. Businesses that are passed by two-way HFC cable in areas where
the @Home service has been launched can connect to the @Work Internet service
without paying for local telephone circuits. The @Work Internet HFC service
offers peak data transmission speeds of 10 Mbps downstream and 384 Kbps
upstream using the @Network. The @Work Internet service is currently
 
                                      39
<PAGE>
 
available in five major metropolitan markets: Chicago, Hartford, San Diego,
the San Francisco Bay Area and Seattle.
 
  @Work Remote. The Company has developed the @Work Remote service to offer
secure, high-speed telecommuting solutions via HFC cable and virtual private
networks among remote users, branch offices and a corporate LAN. The @Work
Remote service includes the network equipment and software needed to connect
the corporate LAN securely to the @Network via high-bandwidth local telephone
circuits. Users will be able to gain secure access to all of their corporate
LAN resources 24 hours a day, seven days a week. The Company offers virtual
private network capability between branch offices and corporate headquarters.
The Company is currently negotiating arrangements with the Cable Partners to
offer the @Work Remote service over the cable infrastructure for
telecommuters.
 
  The Company's future @Work services offerings are expected to include
internal corporate multicasting, "push-based" multimedia content delivery and
geographically distributed Web site hosting services. In addition, by
designing each RDC to include high-availability, high-performance servers and
mass storage, the Company will have the ability to deliver and facilitate
next-generation client-server and distributed-object networked business
applications.
 
  @MEDIA SERVICES AND TECHNOLOGIES
   
  The @Media group sells advertising and, in partnership with content
providers, packages advertising-supported transaction and premium services
that it will offer to @Home subscribers. Advertisers and content providers can
utilize @Media technologies that enable them to exploit the high-bandwidth,
multimedia capabilities of the @Network. In addition, the @Media group
provides the programming services that aggregate the high-quality and
compelling multimedia content delivered through the @Home Guide, the
cornerstone of the @Home Experience. See "Risk Factors--Dependence on High-
Quality Content Provision and Acceptance; Developing Market for High-Quality
Content."     
   
  The @Media group sells advertising through the "B*box," a broadband
audio/video advertising space located in the @Home Guide. With the B*box,
advertisers are not constrained by the Web banner paradigm and can broaden
their creative presentation using video clips, near-CD-quality audio and
animation. Advertisers have the ability to enhance their message by using
multimedia tools and technologies such as Shockwave, Quicktime Video and Real
Audio. The Company has a broad range of revenue-generating advertisers,
including General Motors, Toyota and Unilever. Advertisers have reported
response rates (click-throughs) substantially greater than they currently
experience with traditional Web banner advertisements. The Company believes
that advertisers' ability to present more compelling messages to online users
will lead to advertising rates greater than those charged for banner
advertising on the Web.     
 
  The Company believes that growth in its subscriber base will be critical to
attracting advertisers. In addition to traditional sales and marketing
efforts, the Company has developed a variety of compelling programming
services delivered through the @Home Guide in order to drive incremental
subscriber penetration. In addition to receiving advertising fees, the @Media
programming services provide a variety of revenue sources. Examples of @Media
programming services include:
 
    Real-Time News and Entertainment Services: Continuously-updated,
  scrolling headlines delivered via the News Carousel in the News, Sports and
  Business @Home Guide channels, and video clips presenting top stories,
  sports highlights and movie previews. Current @Media partners include
  Bloomberg, CNET, CNN, MSNBC, SportsLine, The New York Times and USA Today.
     
    Enhanced Search and Directory Services: Leading search and directory
  services integrated into the @Home Guide. The Company shares in the
  advertising revenue generated from these services. Current @Media partners
  include BigBook, Excite, Infoseek, Switchboard, WhoWhere, Yahoo! and Zip2.
         
    Online Services: Offer content of major OSPs via the @Home Guide in order
  to take advantage of the @Network's high data transmission speed. The
  Company will offer MSN as a premium service through current @Media partner
  Microsoft.     
 
                                      40
<PAGE>
 
    Digital Audio Services: Near-CD-quality audio on various music, talk and
  event channels (e.g. jazz, rock and 24-hour sports talk) via the Company's
  TuneIn service. Users can simultaneously listen to TuneIn and browse the
  Internet without a material degradation in download speeds. Current @Media
  partners include CNET Radio, Net Radio, SportsLine and TheDJ.
     
    Software Purchase with Real-Time Downloading: Purchase and download
  software titles at speeds substantially faster and with greater reliability
  than a typical dial-up modem. A current @Media partner, CNET, provides its
  BuyDirect.com service.     
     
    High-Speed Multiplayer Gaming: Download and play popular Internet games
  against other online players, delivered via @Home Games, an @Home Guide
  channel. A current @Media partner, CNET, provides its gamecenter.com
  service.     
     
    Interactive Shopping: Evaluate and purchase goods via an interactive
  multimedia shopping experience. Current @Media partners include iQVC and
  Music Boulevard.     
   
  The @Media group offers a series of technologies to assist advertisers and
content providers in delivering compelling multimedia advertising and premium
services, including Replicate, DirectConnect, M-Cast and KnowledgeAPI.
Replicate enables the Company's content partners to place copies of their
content and applications locally on the @Network. DirectConnect allows content
providers to connect directly to the @Network without traversing the congested
Internet, further accelerating transmission speeds between popular sites and
services. M-Cast enables the efficient multicasting of advertising, content
and services such as continually updated news and sports information, video
clips and audio from one source to many subscribers simultaneously.
KnowledgeAPI is software that enables the personalization and targeting of
both content and advertising to specific interest groups based on subscriber-
provided profile information. For example, for an @Home Games multiplayer
online game, the Company could utilize Replicate to enable fast downloading of
the game software, DirectConnect to minimize the latency between users and the
game server (enabling an interactive "fast-twitch" experience), M-Cast to
distribute realtime game-play positional data efficiently to all simultaneous
players, and KnowledgeAPI to match gamers with similar interests.     
 
@NETWORK ARCHITECTURE
 
  The Company designed the @Network on the premise that sustainable, high-
performance Internet access requires a new, scalable architecture to alleviate
Internet bottlenecks and to enable true end-to-end network management
capabilities. The Company has developed and implemented its scalable,
distributed intelligent network architecture that links a private high-speed
nationwide backbone with Cable Partners' HFC systems and the TCG
infrastructure. To ensure compatibility and seamless access to the Internet,
this high-performance "parallel Internet" uses the same underlying
communications protocols and is effectively one of the world's largest
intranets. Residential subscribers access the network primarily through high-
speed cable modems, which attach to their personal computers via a standard
Ethernet connection, while businesses can also connect through CLEC
telecommunications networks. The two key principles of the Company's network
strategy are moving data closer to the user and end-to-end network management.
   
  Moving Data Closer to the User. The @Network utilizes caching and
replication technologies to move the information that a subscriber requests
close to the subscriber. While communications costs have dropped over time,
the cost of processing and storing data has diminished more rapidly. In
addition to this fundamental shift in the economics of processing and storage
versus communications, local caching dramatically reduces backbone network
traffic enabling the @Network to overcome a fundamental weakness of the
Internet--duplicative data transfers. For example, when a subscriber downloads
a video clip from a Web site, the user must "pull" data across the Internet
from that Web site to the user's ISP and finally to the user's computer. If
the user's neighbor requests the same video clip from that Web site, the
neighbor must pull the same data across a similar path. In contrast, the
Company's approach would move the video clip over its high-speed backbone only
once in a given geographic area and retain it in a local cache near the user's
home where it could be accessed by every subscriber within that area without
retransmission over the backbone. This more cost-effective approach
simultaneously improves the end user's performance and reduces traffic volume
across the backbone.     
 
                                      41

  End-to-End Network Management. End-to-end network management is achieved
through the Company's proactive network quality, service and performance
management systems. The @Network provides visibility from the Company's
servers (or content partners' servers) across the backbone and all the way to
the subscriber's home. Because the @Network is centrally managed, the Company
can dynamically identify and enhance network quality, service and performance
or address issues before they affect the user experience.
 
  The primary components of the @Network are the Company's high-speed private
national backbone, RDCs, regional networks, headends (including caching
servers), network connections and cable modems and the Network Operations
Center.
 
  Private National Backbone. The Company operates its own private national
backbone, which consists of a network of high-speed asynchronous transfer mode
("ATM") communications services that the Company leases to connect its RDCs
and regional networks with content providers and the Internet. These services
currently operate at a speed of 45 Mbps and can be upgraded to 155 Mbps. This
backbone can be viewed as a high-speed "parallel Internet" that connects via
the Company's routers to the Internet at multiple network access points
("NAPs") with "Tier-One" peering status, which permits the Company to exchange
Internet traffic with other nationwide ISPs. The Company's backbone approach
provides a high performance, cost-effective, scalable transport facility that
can extend service to new areas without requiring frequent network topology
reconfigurations.
   
  Regional Data Centers. The RDCs act as service hubs for defined geographic
areas, such as major metropolitan areas, providing key services, including e-
mail, news groups and chat facilities, to subscribers, managing network
performance proactively, replicating content and applications, and providing
an economical infrastructure to cache and multicast data throughout a region
and to house local content and subscribers' Web pages. The Company uses state-
of-the-art "high-availability" servers in its RDCs for these mission-critical
activities in order to provide the maximum service availability that consumers
and commercial subscribers expect. To date, the Company has deployed RDCs in
14 geographic areas. The Company estimates that to provide the @Home service
throughout North America will eventually require it to deploy between 30 and
50 RDCs.     
   
  Regional Networks. The regional networks consist of network routers and
switches that interconnect the Company's RDCs and its national backbone to
multiple cable headend facilities at speeds of 45 Mbps to 155 Mbps. These
networks generally take advantage of cable operators' fiber optic
infrastructures that are normally used to transport cable television signals
from a consolidated master headend facility to other headends within a region.
This approach often allows the Company to avoid the high cost of leasing
conventional high-speed communication services from local telephone companies
when deploying high-speed connectivity in a region.     
   
  Headends. The cable system headends are connected to each RDC through the
regional network. In order to move data as close to the subscriber as possible
and to avoid repetitive transmission of the same data, the headends employ
high-performance caching servers that store frequently accessed content
locally, thereby greatly reducing the amount of data transmission (and
corresponding transport costs) in higher layers of the network. In addition,
local caching servers can compile far more comprehensive usage data than is
normally attainable on the Internet, which data can be used for network
troubleshooting, tuning performance and tailoring the service. Additional
caching servers and/or storage capacity can be added economically as
penetration in a particular community grows, increasing the ability to support
additional service demand without significant capital outlay.     
   
  Network Connections and Cable Modems. The last leg of the network connection
is from the headend to the consumer over a cable operator's HFC cable system.
Multiple fiber optic lines carry the signal from the headend out to cable
"nodes" in each neighborhood, which in turn connect through traditional
coaxial cable to the home. These fiber optic nodes typically service from 300
to 2,000 homes in a relatively modern cable system. In such a system, each
television channel requires 6 MHz of the 450-750 MHz of total system capacity.
Downstream transmission of the @Home service utilizes a similar channel. As
subscriber penetration increases,

Graphic depicts the network architecture of the @Network.  The graphic 
illustrates the connections among the various components of the @Network, 
including network access points (NAPs) to the Internet, private national 
backbone, regional networks, RDCs, headends and buildings.  A caption at the 
lower left of the graphic illustrates the connections, at the home, among two-
way HFC cable, a cable modem, an ethernet card and a personal computer. A legend
at the lower right of the graphic identifies the following services depicted as
images on the graphic along with the following peak data transmission speeds:
(i) @Home (Downstream--up to 27 Mbps; Upstream--up to 10 Mbps); (ii) @Work
Remote (Downstream--up to 27 Mbps; Upstream--up to 10 Mbps); and (iii) @Work
Internet (up to 45 Mbps). The legend also identifies the Regional Network and
its peak data transmission speed of 45-155 Mbps, as well as a line that
illustrates the @Work Virtual Private Network capability.

it may be necessary for the LCO to add additional nodes in order to maintain
adequate downstream data transmission speeds although there is no obligation
for the LCO to do so. Upstream transmission, however, utilizes a frequency
range not used for traditional broadcast by cable systems. This range is more
prone to interference than downstream channels, which effectively limits the
peak upstream transmission speed. In such a two-way system, no use of telephone
line facilities in the home is required. In the home, a cable modem connects to
the cable television coaxial wiring and attaches to the user's personal
computer via standard Ethernet connections. Cable modems are manufactured by a
variety of vendors, including Motorola and Bay Networks. The peak data
transmission speed of a cable modem depends on the specific model and can
approach 27 Mbps downstream and 10 Mbps upstream. Even when cable modems
operate at these speeds, however, the performance that subscribers actually
experience is often constrained by their operating systems, software and
hardware. See "Risk Factors--Unproven Network Scalability and Speed."     
   
  The @Network is "always on" unlike switched technologies such as dial-up and
ISDN. The coaxial cable connection from the neighborhood node to the home is a
medium shared among those subscribers attached to a given fiber optic node or a
number of combined fiber optic nodes. Proximate users share high-bandwidth
access (much like corporate LANs) and may limit the effective bandwidth that is
available to a given subscriber at a given time. However, this shared
connection is particularly efficient and well suited to the sporadic nature of
Internet traffic, where browsing tends to consume bandwidth in discrete bursts
intermixed with periods of inactivity. As subscriber penetration increases, the
cable operator has multiple cost-effective alternatives to increase capacity,
including allocating additional 6 MHz channels for the @Home service or
reducing the number of subscribers sharing a given bandwidth by adding nodes
housing lasers and transmitters, with each node serving a smaller number of
subscribers over the same fiber-optic infrastructure. These approaches allow
the cable operator to fine-tune both the amount of bandwidth available and the
number of users sharing that bandwidth, and to increase bandwidth incrementally
as subscriber penetration in a market increases.     
   
  Network Operations Center. The Company provides end-to-end network management
through its NOC. The NOC uses advanced network management tools and systems to
monitor the network infrastructure on a 24X7 basis, enhancing its ability to
address performance bottlenecks before they affect the user experience. From
the NOC, the Company can manage the @Network from end-to-end, including the
backbone, RDCs, regional networks, headends facilities, servers and other
components of the network infrastructure to the user's home. See "Risk
Factors--Risk of System Failure."     
 
  The Company also utilizes certain key technologies from third parties to
build and manage the @Network. In particular, the Company has established
strategic relationships with Sun for high availability servers, SGI for caching
servers, Cisco for network routing and switching hardware, Sprint for national
switched ATM backbone services, OSI for network management software, Tivoli for
systems management software to operate RDCs remotely, Oracle for advanced
database management software and Netscape for server and browser software. See
"Risk Factors--Dependence on Key Technology Suppliers."

STRATEGIC DISTRIBUTION RELATIONSHIPS
   
  Strategic Relationships with Cable Partners. The Company has strategic
relationships with seven leading cable companies whose systems pass
approximately 44 million homes. Subject to certain exceptions, the Company's
Principal Cable Stockholders, TCI, Comcast and Cox, have granted the Company
the exclusive right to offer high-bandwidth residential consumer Internet
services over their cable systems for an agreed period. Rogers and Shaw have
agreed to market and promote the @Home service under the name "Wave@Home" in
Canada. In addition, Marcus and Intermedia have entered into agreements to
distribute the @Home service through certain of their cable systems. The
following table sets forth the number of homes passed by the cable systems of
each of the Cable Partners and the principal cities and communities served by
their cable systems. See "Risk Factors--No Obligation of Principal Cable
Stockholders to Carry the Company's Services; Limitations on Their
Exclusivity."

 * TCI has recently announced the proposed sale of cable systems having
   approximately 1.4 million homes passed to other cable companies with which
   the Company does not have distribution arrangements. See "Risk Factors--
   Potential Disposition of Cable Systems by Principal Cable Stockholders."
          
** Represents total homes passed by all of the Cable Partners' cable systems.
   The Company has agreements for distribution of its @Home service only with
   respect to the cities and communities listed, which represent a small
   portion of the total homes passed.     
   
  The Company believes that approximately two million of these homes are
currently passed by upgraded two-way HFC cable and that the Cable Partners
will complete the upgrade of systems passing a majority of these homes within
five years. However, Cable Partners have limited experience with these
upgrades, and these investments have placed a significant strain on the
financial, managerial, operating and other resources of the Cable Partners,
most of which are already highly leveraged, and thus have been, and the
Company expects will continue to be, subject to change, delay or cancellation.
Although the Company's commercial success depends on the successful and timely
completion of these infrastructure upgrades, the Cable Partners are under no
obligation to the Company to upgrade systems or to roll out, market or promote
the Company's services. In addition, none of the Cable Partners has agreed to
any specific schedule for rolling out two-way HFC infrastructure improvements,
and the Cable Partners are not contractually required to achieve any specific
rollout schedule. Because of the very substantial capital cost of upgrading
cable systems for high-speed two-way data transmission, there has been
uncertainty in recent months as to the rate at which the Cable Partners and
other cable system operators will upgrade their systems. See "Dependence on
Cable Partners to Upgrade to Two-Way Cable Infrastructure Necessary to Support
the @Home Service; Uncertain Availability and Timing of Upgrade." As of June
18, 1997, the Company had more than 6,000 subscribers in the United States and
was in the process of converting to its @Home service approximately 5,000
subscribers currently receiving the Wave interactive

service provided by Rogers and Shaw in Canada. To date, TCI, Comcast, Cox and
Intermedia have launched the @Home service in portions of the 13 cities and
communities (of which 11 have revenue-paying subscribers) set forth in the
following table.

*In market trials
   
  In order to shorten time to market for cable operators, the Company provides
a turnkey solution, which includes not only a technology platform, but also a
national brand, marketing, customer service and billing. This solution enables
the Cable Partners to leverage their respective infrastructures to deliver
high-bandwidth interactive data services that represent significant new
revenue opportunities. The Company's Cable Partners have the additional
opportunity to develop and receive all the revenues derived from local content
distributed locally though portions of the @Network to local subscribers. The
Cable Partners bear the cost of upgrading and maintaining their cable systems
to provide high-speed two-way data transmission, installing the @Home service
in subscribers' homes, procuring the cable modems needed to interface with the
@Network and local marketing efforts. See "Risk Factors--Dependence on Cable
Partners to Roll Out, Market, Install, Maintain Infrastructure for, Provide
Customer Service for and Bill for the @Home Service."     
   
  The @Home service is currently offered to consumers in the United States for
flat monthly fees generally ranging from $35 to $55, including a cable modem
provided by the Cable Partner. Installation of the @Home service is provided
by the Cable Partner at a price generally ranging from $75 to $175. Under the
current United States Cable Partner arrangements, the Company receives 35% of
monthly fees and fees for premium services, and the Cable Partner retains the
entire installation payment. In Canada, the Company will receive a smaller
percentage of the monthly subscription fees billed by Rogers, Shaw and their
sub-distributors because Rogers and Shaw will bear the costs of providing
additional customer support, data transport, marketing and programming for the
Canadian market which are not borne by the Company's Cable Partners in the
United States. In international markets, the Company anticipates that the
subscriber pricing and revenue or royalty splits with cable system operators
will be different from those that prevail in the United States based on
differences in services and content provided by the Company and the cable
system operators, data transport costs and regulatory environments. To the
extent that the Company offers terms of distribution and other services that
are more favorable than those offered to the Principal Cable Stockholders,
they have the right to obtain such more favorable terms under a "most favored
nation" provision in the Master Distribution Agreement. See "Certain
Transactions--Certain Business Relationships--Master Distribution Agreement
with TCI, Comcast and Cox."     
 
  Strategic Relationship with TCG. The Company has established a strategic
relationship with TCG to provide facilities management and telecommunications
network services for the local transport requirements of the Company's @Work
services. TCG, of which TCI, Comcast and Cox control a majority of the voting
stock, is the largest CLEC in the United States, providing high-speed fiber
optic telecommunications services to more than 7,700 commercial customer sites
in 57 major metropolitan centers in the United States. The Company's access to
TCG's fiber optic network and switching infrastructure gives the Company a
nationwide opportunity in the commercial marketplace, which the Company
believes will accelerate the deployment of the Company's @Work services into
major United States markets. As the Company's @Work services grow, the Company
believes that its strategic relationship with TCG will provide TCG the
benefits of driving additional traffic volumes over TCG's existing networks
and generating significant incremental revenues for TCG. See "Risk Factors--
Dependence on TCG for Local Telecommunications Services for the @Work
Services."

DISTRIBUTION, MARKETING AND SALES
   
  The Company has entered into distribution arrangements for the @Home service
with TCI, Comcast, Cox, Rogers, Shaw, Marcus and Intermedia, whose cable
systems pass approximately 44 million homes in North America. To expand
distribution, the Company is aggressively seeking to work with additional
United States and international cable companies to obtain exclusive rights to
their coverage areas. The Company is also exploring alternative delivery
mechanisms such as the use of telephone return and the use of high-speed
telecommunications services for MDUs. The Company has developed a
comprehensive set of step-by-step plans and certification processes to verify
that cable companies have upgraded their cable systems to a two-way HFC cable
infrastructure that is capable of delivering the Company's services. The
Company's marketing strategy is to accelerate penetration within its
geographic markets by creating awareness of the "@Home" brand, making it
synonymous with a compelling online interactive multimedia experience. The
Company executes this strategy through cooperative promotional programs with
the Company's Cable Partners, which are licensed by the Company to use the
"@Home" brand in conjunction with their own brands in the distribution of the
Company's services. Ultimately, the Company plans to leverage its growing
subscriber base by marketing services that provide incremental revenue
opportunities such as advertising, premium subscriber services and @Work
value-added services. See "Risk Factors--Dependence on Cable Partners for
Distribution; Potential Conflicts of Interest with Principal Cable
Stockholders."     
 
  @Home Service. The @Home service is sold to consumer households by the Cable
Partners in the markets they serve. While the Cable Partners have the primary
responsibility for locally marketing the service, the Company assists them in
local market planning and product promotions by providing templates and
materials for print, direct mail and broadcast advertising. The Company also
believes that retailers and original equipment manufacturers ("OEMs") may
provide a major opportunity for the Company to gain exposure to a much wider
audience of consumers, provide hands-on demonstrations and increase subscriber
penetration by certifying products such as personal computers and cable modems
as "@Home Ready" and developing "@Home-branded" products.
 
  @Work Services. The Company's sales and marketing strategy for its @Work
services utilizes both a direct sales force and indirect sales channels. The
Company engages in direct sales through a National Account Team and a Valued
Account Team. The National Account Team proactively calls on senior executives
and chief information officers at Fortune 1,000 companies in regions where the
@Work services are available. These sales are typically complex in nature and
involve businesses with significant integration needs and multiple sites. The
Valued Account Team consists of both inbound and outbound telesales
representatives and focuses on sales to non-Fortune 1,000 companies. This team
responds to call activity and leads generated through @Work marketing
activities, including direct mail, online Web promotion and advertising,
national and regional industry events, @Work seminars, promotional programs
and pursuit of favorable industry analyst and press coverage. The indirect
sales team works with @Work partner companies to leverage their sales forces
to sell @Work services. Indirect sales partners include OEMs, value added
resellers and systems integrators. The Company also plans to establish
distribution arrangements for the @Work services through its Cable Partners.
 
  @Media Services and Technologies. The Company sells advertising to national
consumer businesses through a direct sales force and attracts advertisers by
providing a series of services and technologies through its Interactive
Advertising Group. The Company's Interactive Advertising Group, which consists
of advertising production resources, ad program management personnel and a
traditional commissioned advertising sales team, works with advertisers to
develop compelling advertising for the Internet. The Company's Media
Development Team works with leading content and application providers to
package access to premium subscription offerings. The Company and its Cable
Partners market these offerings to subscribers to the @Home service through
online and traditional media.
 
  International Markets. The Company believes that international markets will
provide a substantial opportunity for its services. Simba Information Inc.
projects that there will be 21 million online and Internet users outside North
America in 2000. The Company expects that many of its services will be highly
transferable to international markets, recognizing that some degree of
localization of content will be essential to achieving
 
                                      47
<PAGE>
 
   
success. Accordingly, the Company plans to address targeted international
markets though local partners that will market, sell and distribute the
Company's services in their countries. The international markets that the
Company plans to target first are Canada, the United Kingdom, Germany, Japan
and France. In March 1997, the Company entered into exclusive arrangements for
the distribution of its @Home service under the name "Wave@Home" in Canada
through Rogers and Shaw, the two leading cable system operators in Canada,
whose systems reach approximately five million homes or 50% of the homes
passed by cable in Canada. Through Rogers and Shaw, which have the right to
redistribute the Wave@Home service to other cable system operators in Canada,
the Company expects to expand the distribution of its service into Canada.
    
CUSTOMER SERVICE AND TECHNICAL SUPPORT
 
  The Company believes that inadequate customer service and technical support
represent a major shortcoming of Internet access services. The Company and its
Cable Partners have developed a comprehensive approach for managing all
subscriber interactions, including installation, billing and transaction
management, technical support and customer service, intended to ensure that
every interaction a subscriber has with the Company's services is a positive
experience. The @Home service is typically installed in the subscriber's home
by a trained computer technician and a cable technician both provided by the
Cable Partner. The Company assists the Cable Partners in training the service
installers, provides automated installation processes and collateral materials
and, in some cases, coordinates installation schedules. To ensure ongoing
customer satisfaction, the Company and the Cable Partners provide three tiers
of customer service and technical support: general customer service (Tier 1);
technical support (Tier 2); and network management support (Tier 3). Tier 1
support, including billing, is typically the responsibility of the Cable
Partner, although the Company offers the full range of service and support as
a complete outsourced solution, and the Cable Partner has the option of
contracting with the Company for Tier 1 support at the Company's cost.
Alternatively, the Cable Partner may elect to provide Tier 2 support and
reduce the revenue split paid to, or otherwise be compensated by, the Company.
The Company provides an open "ServiceAPI" for cable operators to integrate
their existing billing, service and support systems with the Company's
systems. All of these programs are supported by "@Home University," which
provides a comprehensive set of education services to assist the Cable Partner
in training installers and customer service representatives and training
developers on implementing the ServiceAPI.
   
  The Company's technical support personnel are co-located with the Company's
NOC staff, who are responsible for monitoring the performance of the @Network
from end-to-end on a 24X7 basis. The co-location of these two organizations
facilitates close collaboration between the two groups to resolve subscriber
problems more rapidly and to anticipate potential problems before they can
affect the user experience. The Company utilizes customized network tools that
enable its technical support staff to deliver solutions that would otherwise
require advanced engineering analysis. The Company is also developing a state-
of-the-art knowledge base system to capture and organize the latest
information to meet the needs of the Company's technical support staff, cable
partners and subscribers. By leveraging its integrated subscriber management
systems and technical support database, the Company plans to provide an online
customer support service known as "Help@Home," which will enable comprehensive
access to its service and support knowledge base by both subscribers and cable
operators through the Web, e-mail or interactive voice response.     
 
COMPETITION
   
  The markets for consumer and business Internet services and online content
are extremely competitive, and the Company expects that competition will
intensify in the future. The Company's most direct competitors in this market
are ISPs, national long distance carriers, local exchange carriers, wireless
service providers, OSPs and Internet content aggregators. Many of these
competitors are offering (or may soon offer) technologies that will attempt to
compete with some or all of the Company's high-speed data service offerings.
Such technologies include ISDN and xDSL. The Company also competes with other
cable-based data services that are seeking to contract with cable system
operators to bring their services into geographic areas that are not covered
by an exclusive relationship between the Company and its Principal Cable
Stockholders. The bases of competition in these markets include transmission
speed, reliability of service, ease of access, price/performance, ease-of-use,
    
                                      48
<PAGE>
 
content quality, quality of presentation, timeliness of content, customer
support, brand recognition, operating experience and revenue sharing. The
Company believes that it compares favorably with its competitors with respect
to each of these factors, except brand recognition, which the Company is
starting to build. However, many of the Company's competitors and potential
competitors have substantially greater resources than the Company, and there
can be no assurance that the Company will be able to compete effectively in
its target markets.
 
  Internet Service Providers. ISPs, such as BBN, Earthlink, MindSpring, Netcom
and PSInet, provide basic Internet access to residential consumers and
businesses, generally using existing telephone network infrastructures. This
method is widely available and inexpensive, but performance is limited.
Barriers to entry are low, resulting in a highly competitive and fragmented
market.
 
  National Long Distance Carriers and Local Exchange Carriers. Long distance
inter-exchange carriers, such as AT&T, MCI, Sprint and WorldCom, have deployed
large-scale Internet access networks and sell connectivity to business and
residential customers. The RBOCs and other local exchange carriers have also
entered this field and are providing price competitive services.
   
  Wireless Service Providers. Wireless service providers, including AT&T and
Hughes Network Systems, are developing wireless Internet connectivity, such as
MMDS, LMDS and DBS. MMDS and LMDS are not yet available and will require radio
frequency spectrum auctions before service is possible. They will also require
an entirely new distribution infrastructure and new equipment including
specialized modems.     
 
  Online Service Providers. OSPs include companies such as America Online,
CompuServe, MSN, Prodigy and WebTV that provide, over the Internet and on
proprietary online services, content and applications ranging from news and
sports to consumer video conferencing. These services are designed for broad
consumer access over telecommunications-based transmission media, which
enables the provision of data services to the large group of consumers who
have personal computers with modems. In addition, they provide basic Internet
connectivity, ease-of-use and consistency of environment. In addition to
developing their own content or supporting proprietary third-party content
developers, online services often establish relationships with traditional
broadcast and print media outlets to bundle their content into the service,
such as Microsoft's relationship with NBC to provide multimedia news and
information programming over both cable television and MSNBC.
 
  Internet Content Aggregators. Content aggregators seek to provide a "one-
stop" shop for Internet and online users. Their success depends on capturing
audience flow, providing ease-of-use and offering a range of content that
appeals to a broad audience. Their business models are predicated on
attracting and retaining an audience for their set of offerings. Leading
companies in this area include America Online, CompuServe, Excite, Microsoft
and Yahoo!. In this market, competition occurs in acquiring both content
providers and subscribers. The principal bases of competition in attracting
content providers include quality of demographics, audience size, cost-
effectiveness of the medium and ability to create differentiated experiences
using aggregator tools. The principal bases of competition in attracting
subscribers include richness and variety of content and ease of access to the
desired content. The proprietary online services such as America Online,
CompuServe and MSN have the advantage of a large customer base, industry
experience, many content partnerships and substantial resources.
   
  Cable-Based Data Services. The Company's competitors in the cable-based
services market are those cable companies that have developed their own cable-
based services and market those services to unaffiliated cable system
operators that are planning to deploy data services and with which the Company
would like to work. Several cable system operators, including Time Warner and
US West's Continental Cablevision subsidiary, have deployed high-speed
Internet access services over their existing local HFC cable networks.
Specifically, Time Warner, which is the second largest cable company in the
United States, has established its own cable-based ISP with proprietary
content service, called Road Runner, which features a variety of Time Warner
publications and services. Time Warner plans to market the Road Runner service
through Time Warner's own cable systems as well as to other cable system
operators nationwide. Continental Cablevision has developed another service

customers. Others that have publicly

announced limited-area trials for their own cable-based Internet services
include Adelphia, BellSouth and Jones Intercable. Some of these companies such
as Time Warner have their own substantial libraries of multimedia content and
the other competitors could establish strategic relationships with content
providers, which could provide them with a significant competitive advantage.
       
  Many of the Company's competitors and potential competitors have
substantially greater financial, technical and marketing resources, larger
subscriber bases, longer operating histories, greater name recognition and
more established relationships with advertisers and content and application
providers than the Company. Such competitors may be able to undertake more
extensive marketing campaigns, adopt more aggressive pricing policies and
devote substantially more resources to developing Internet services or online
content than the Company. There can be no assurance that the Company will be
able to compete successfully against current or future competitors or that
competitive pressures faced by the Company will not materially adversely
affect the Company's business, operating results or financial condition.
Further, as a strategic response to changes in the competitive environment,
the Company may make certain pricing, service or marketing decisions or enter
into acquisitions or new ventures that could have a material adverse effect on
the Company's business, operating results or financial condition. See "Risk
Factors--Competition."     
 
PRODUCT DEVELOPMENT AND ENGINEERING
 
  The Company's product development and engineering efforts focus on the
design and development of new technologies and products to increase the speed
and efficiency of the @Network and to facilitate the development and
distribution of high bandwidth over its network. The principal areas of
current product development and engineering include:
 
  . enhancing caching and replication techniques to improve network
    performance and efficiency;
 
  . advancing multicasting technologies to provide efficient transport of
    "one-to-many" content;
     
  . adapting the Company's network services for use over non-HFC access
    technologies, such as xDSL and conventional twisted-pair ethernet wiring
    in MDUs;     
 
  . developing advertisement targeting and content personalization systems to
    fit desired subscriber profiles;
 
  . developing virtual private network technology solutions to enable secure
    and scalable end-to-end telecommuting and commercial services over the
    @Network;
     
  . enhancing the Company's advanced network management capabilities to
    identify and address network performance issues before they affect the
    user experience;     
 
  . developing advanced directory and certification services to enable the
    Company's subscribers to perform electronic commerce and access
    information and premium resources securely; and
 
  . defining application programming interfaces for TV-based Internet devices
    that can browse and interact with the Web without requiring the use of a
    personal computer.
 
  The Company's product development and engineering expenses for the period
from March 28, 1995 (inception) to December 31, 1995, 1996 and the first
quarter of 1997 were $1.4 million, $6.3 million and $2.3 million,
respectively.
 
INTELLECTUAL PROPERTY
 
  The Company regards its technology as proprietary, attempts to protect it
with copyrights, trademarks, trade secret laws, restrictions on disclosure and
other methods, and has filed one patent application and is in the process of
preparing additional patent applications with respect to aspects of its high-
bandwidth network technology and online advertising. There can be no assurance
that any patent will issue from these applications or that, if issued, any
claims allowed will be sufficiently broad to protect the Company's technology.
In addition, there can be no assurance that any patents that may be issued
will not be challenged, invalidated or circumvented, or that any rights
granted thereunder would provide proprietary protection to the Company.
Failure of any patents to provide
 
                                      50
<PAGE>
 
protection to the Company's technology may make it easier for the Company's
competitors to offer technology equivalent or superior to the Company's
technology. The Company also generally enters into confidentiality or license
agreements with its employees and consultants, and generally controls access
to and distribution of its documentation and other proprietary information.
Despite these precautions, it may be possible for a third party to copy or
otherwise obtain and use the Company's products, services or technology
without authorization, or to develop similar technology independently. In
addition, effective copyright, trademark and trade secret protection may be
unavailable or limited in certain foreign countries, and the global nature of
the Internet makes it virtually impossible to control the ultimate destination
of the Company's content offerings. Policing unauthorized use of the Company's
content offerings is difficult. There can be no assurance that the steps taken
by the Company will prevent misappropriation or infringement of its
technology. In addition, litigation may be necessary in the future to enforce
the Company's intellectual property rights, to protect the Company's trade
secrets or to determine the validity and scope of the proprietary rights of
others. Such litigation could result in substantial costs and diversion of
resources and could have a material adverse effect on the Company's business,
operating results and financial condition.
 
  From time to time, the Company has received, and may receive in the future,
notice of claims of infringement of other parties' proprietary rights,
including claims for infringement resulting from the downloading of materials
by the online or Internet services operated or facilitated by the Company.
There can be no assurance that infringement or invalidity claims (or claims
for indemnification resulting from infringement claims) will not be asserted
or prosecuted against the Company or that any assertions or prosecutions will
not materially adversely affect the Company's business, operating results and
financial condition. Irrespective of the validity or the successful assertion
of such claims, the Company would incur significant costs and diversion of
resources with respect to the defense thereof, which could have a material
adverse effect on the Company's business, operating results and financial
condition. If any claims or actions are asserted against the Company, the
Company may seek to obtain a license under a third party's intellectual
property rights. There can be no assurance, however, that under such
circumstances a license would be available on commercially reasonable terms,
or at all.
 
EMPLOYEES
   
  As of March 31, 1997, the Company had 246 employees, excluding temporary
personnel and consultants. Of the total, 60 were employed in networking
engineering, 75 supported the @Home service including customer support and
related activities, 27 supported the @Work services, 53 were employed in the
@Media group and 31 were employed in general and administration. None of the
Company's employees is represented by a labor union, and the Company considers
its relations with its employees to be good. The Company's ability to achieve
its financial and operational objectives depends in large part upon the
continued service of its senior management and key technical personnel and its
continuing ability to attract and retain highly qualified technical and
managerial personnel. Competition for such qualified personnel in the
Company's industry and geographical location in the San Francisco Bay Area is
intense, particularly in software development, network engineering, cable
engineering and product management personnel. See "Risk Factors--Management of
Growth and Expansion; Dependence on Key Personnel."     
 
FACILITIES
   
  The Company is headquartered in facilities consisting of approximately
70,000 square feet in Redwood City, California, which the Company occupies
under a 12-year lease. In connection with this lease, the Company is obligated
to reimburse the landlord for leasehold improvements totaling approximately
$5.5 million. In addition, the Company has three separate options to require
the landlord to build a total of approximately 400,000 additional square feet
of facilities on adjacent property, subject to certain conditions. The Company
would then occupy these buildings under leases of 12 years with base rent to
be determined based on the cost of construction of the buildings. The Company
anticipates that the Redwood City facilities will be adequate for the
foreseeable future.

  Directors are elected by the stockholders at each annual meeting of
stockholders to serve until the next annual meeting of stockholders or until
their successors are duly elected and qualified. The existing directors were
elected pursuant to provisions in the Certificate of Incorporation, a
stockholders' agreement and a voting agreement that will be modified or
replaced effective upon the closing of this offering. See "--Board Composition
and Procedures," "Certain Transactions" and "Description of Capital Stock"
below. Members of the Board do not receive compensation for their services as
directors. Executive officers are elected by, and serve at the discretion of,
the Board.     
 
BOARD COMPOSITION AND PROCEDURES
 
  Immediately following the closing of this offering, the Board will consist
of 11 directors. Under the Company's Certificate of Incorporation, the holders
of the Series B Common Stock, all of which will be owned by a subsidiary of
TCI immediately following this offering, have the right to elect five members
of the Board (the "Series B Common Stock Directors"). TCI has initially
designated Messrs. Clouston, Ravenel and Romrell as Series B Common Stock
Directors. Subject to certain conditions, TCI has also agreed to elect one
representative designated by Comcast and one representative designated by Cox
as Series B Common Stock Directors. Mr. Roberts is the current representative
of Comcast, and Mr. Woodrow is the current representative of Cox. The holders
of the Series K Common Stock, the substantial majority of which is controlled
by KPCB, have the right to elect one director (the "Series K Common Stock
Director"), who is currently Mr. Doerr. So long as the holders of Series B
Common Stock or Series K Common Stock are entitled to elect any Series B
Common Stock Director or any Series K Common Stock Director, the holders of
Series A Common Stock have the right to elect two directors (the "Series A
Common Stock Directors") who are not officers or employees of the Company and
are not affiliates or associates of TCI, Comcast or Cox ("Outside Directors").
 
                                      55
<PAGE>
 
   
Messrs. Barksdale and Hearst are the current Series A Common Stock Directors.
Immediately following this offering, TCI, Comcast and Cox will own
approximately 35.5%, 16.6% and 16.6%, respectively, of the outstanding Series
A Common Stock, and TCI together with either Comcast or/and Cox will have the
ability to elect both of the Series A Common Stock Directors subject to the
requirement that they qualify as Outside Directors. The remaining directors
are elected by the holders of the Common Stock voting together as a single
class. Since TCI holds more than 50% of the outstanding voting power of the
Company's capital stock, it has the power to elect all of these directors.
However, TCI, Comcast, Cox and KPCB have agreed to vote for the election of
the Chief Executive Officer of the Company to the Board. Subject to certain
conditions, TCI, Comcast and Cox have also agreed to vote for the election to
the Board of one representative jointly designated by Rogers and Shaw, who is
currently Mr. Rogers. TCI has elected Dr. Malone to the remaining position on
the Board. In addition, the Certificate of Incorporation provides that, so
long as TCI owns at least 7,700,000 shares of Series B Common Stock and
securities representing a majority of the outstanding voting power of the
Company, there will be a committee of the Board consisting of those Series B
Common Stock Directors who are officers, directors or employees of TCI or any
subsidiary of TCI (the "Series B Committee"), which shall have the sole power,
exercisable at any time, to increase the size of the Board to up to 17
directors and to fill any vacancies created by such an increase. Since four of
the eleven current directors are officers of TCI or a subsidiary of TCI and
TCI has the power, without a meeting of the stockholders, to increase the size
of the Board to up to 17 directors and appoint additional members of the
Board, TCI has the power to appoint a majority of the Board at any time. See
"Risk Factors--Control by TCI; Veto Power of Other Principal Stockholders" and
"Description of Capital Stock."     
   
  Under the Certificate of Incorporation, all actions of the Board must be
approved by (i) a majority of the members of the Board present at a meeting at
which a quorum is present or unanimous written consent of all members of the
Board and (ii) so long as TCI owns at least 7,700,000 shares of Series B
Common Stock and securities representing a majority of the outstanding voting
power of the Company, a majority of the Series B Common Stock Directors.
Accordingly, because TCI has the right to elect three of the five Series B
Common Stock Directors, TCI has the power to prevent the Board from taking any
action that is not approved by its designated Series B Common Stock Directors.
In addition, to the extent that TCI exercises its power to elect a majority of
the entire Board, TCI will be able to control all Board decisions, subject to
the supermajority and unanimous vote requirements and other limitations
discussed below.     
   
  In addition, certain actions of the Board require the approval of at least
75% (currently five of six) of the total number of Series B and Series K
Common Stock Directors, and certain other actions of the Board require the
unanimous approval of all of the Series B and Series K Common Stock Directors.
Accordingly, with the current composition of the Board, actions that require
supermajority approval cannot be taken without the approval of the Series B
Common Stock Directors designated by TCI and at least two of the three
directors designated by Comcast, Cox and KPCB, and actions that require
unanimous approval cannot be taken without the approval of all three of such

  The Certificate of Incorporation specifies certain requirements for the
approval of certain transactions between the Company and any holder of more
than 5% of the voting power of the Company or any affiliate of such holder.
First, such a related party transaction must be approved by a majority of the
members of the Board present at a meeting for which the notice sets forth the
related party transaction and a reasonably detailed description of the matter,
or by unanimous written consent of the Board following such a meeting. In
addition, so long as the holders of Series B Common Stock are entitled to
elect a Series B Common Stock Director, the related party transaction must
also be approved either (i) by a majority of the Series B and Series K Common
Stock Directors who are disinterested with respect to the transaction and by a
majority of all Series B Common Stock Directors regardless of whether they are
disinterested with respect to the transaction or (ii) by all of the Series B
Common Stock Directors regardless of whether they are disinterested with
respect to the transaction. These requirements do not apply to (i)
transactions involving an aggregate amount less than $1,000,000 that are
entered into in the ordinary course of business on arms'-length terms, (ii)
the entering into of LCO Agreements and other agreements for the provision of
ancillary or related services that are on terms no more favorable to the

the Company to affiliates of each other Principal Cable Stockholder without
regard to size, identity or ownership of securities of the Company, (iii) the
entering into or performance under any .Com Agreement or Promotional Agreement
discussed below or (iv) any actions taken by the Series B Committee.
 
 .COM COMMITTEE
 
  The Company's Certificate of Incorporation establishes a committee of the
Board referred to as the ".Com Committee" consisting of the Chief Executive
Officer of the Company and the other members of the Board who are not
affiliated with TCI, Comcast or Cox (currently Messrs. Jermoluk, Barksdale,
Doerr and Hearst) to review and approve certain content and promotional
agreements (".Com Agreements" and "Promotional Agreements") between the
Company and content providers that are affiliates of the Principal Cable
Stockholders. It is the Company's policy to maintain a position of openness
and non-exclusion with regard to entering into such agreements and that such
content providers will not be unfairly advantaged or disadvantaged in their
ability to obtain carriage or promotion on the Company's services by reason of
their relationship with a Principal Cable Stockholder. Accordingly, any .Com
Agreement or Promotional Agreement between the Company and any affiliate of a
Principal Cable Stockholder may be approved by any one of three methods, to be
chosen by the applicable Principal Cable Stockholder: (i) by the authorized
officers of the Company on the Company's standard terms and conditions, (ii)
by a majority of the .Com Committee or (iii) by a majority of the entire Board
including all of the Series B Common Stock Directors.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
  The Company's Compensation Committee was formed in July 1996 to review and
approve the compensation and benefits for the Company's key executive
officers, administer the Company's stock purchase and stock option plans and
make recommendations to the Board regarding such matters. The Compensation
Committee is currently composed of Messrs. Ravenel and Doerr. No interlocking
relationship exists between the Board or Compensation Committee and the board
of directors or compensation committee of any other company, nor has any such
interlocking relationship existed in the past.
 
AUDIT COMMITTEE
 
  The Board has established an Audit Committee to meet with and consider
suggestions from members of management and the Company's internal audit staff,
as well as the Company's independent accountants, concerning the financial
operations of the Company. The Audit Committee also has the responsibility to
review audited financial statements of the Company and consider and recommend
the employment of, and approve the fee arrangements with, independent
accountants for both audit functions and for advisory and other consulting
services. Messrs. Hearst, Ravenel and Woodrow are the members of the Audit
Committee.

EMPLOYEE BENEFIT PLANS
   
  1996 Incentive Stock Option Plan. In January 1996, the Board adopted the
1996 Incentive Stock Option Plan (the "First 1996 Plan"), which was amended in
May 1996. Under the First 1996 Plan, up to 3,000,000 shares of Series A Common
Stock were reserved for issuance. As of March 31, 1997, options to purchase
2,559,426 shares had been exercised (net of repurchases), options to purchase
an additional 175,000 shares of Series A Common Stock at an exercise price of
$.05 were outstanding and 265,574 shares remained available for future grants.
Following the closing of this offering, no additional options will be granted
under the First 1996 Plan. Options granted under the First 1996 Plan are
subject to terms substantially similar to those described below with respect
to options to be granted under the 1997 Equity Incentive Plan; however, the
First 1996 Plan does not provide for issuance of restricted stock or stock
bonus awards.     
   
  1996 Incentive Stock Option Plan No. 2. In July 1996, the Board adopted the
1996 Incentive Stock Option Plan No. 2 (the "Second 1996 Plan"), which was
amended in October 1996. Under the Second 1996 Plan, up to 13,000,000 shares
of Series A Common Stock were reserved for issuance, provided that such number
is reduced by the number of restricted shares sold outside of either the First
1996 Plan or the Second 1996 Plan (6,825,150 such shares were sold through
March 31, 1997 (net of repurchases)). As of March 31, 1997, options to
purchase 3,946,751 shares had been exercised (net of repurchases), options to
purchase 764,250 shares were outstanding at exercise prices ranging from $.05
to $.25 per share, and 1,483,849 shares were available for future grants.
Following the closing of this offering, no additional options will be granted
under the Second 1996 Plan. Options granted under the Second 1996 Plan are
subject to terms substantially similar to those described below with respect
to options to be granted under the 1997 Equity Incentive Plan; however, the
Second 1996 Plan does not provide for issuance of restricted stock or stock
bonus awards.     
 
 
                                      59
<PAGE>
 
   
  1997 Equity Incentive Plan. In May 1997, the Board adopted and in June 1997
the stockholders approved the 1997 Equity Incentive Plan, under which the
total number of shares of Series A Common Stock reserved for issuance is
16,000,000 less: (a) the total number of shares issued by the Company under
(i) restricted stock purchase agreements entered into prior to the effective
date of the 1997 Equity Incentive Plan with employees, officers, directors,
consultants, independent contractors or advisors of the Company and (ii) the
First 1996 Plan or the Second 1996 Plan (the "1996 Plans") pursuant to the
exercise of options granted on or before the effective date of the 1997 Equity
Incentive Plan; (b) shares that are issuable as of the effective date of the
1997 Equity Incentive Plan upon exercise of options granted under the 1996
Plans; and (c) shares issued as of any date under the Company's 1997 Employee
Stock Purchase Plan.     
   
  Shares that: (a) are issuable upon exercise of an option granted under the
1996 Plans or under the 1997 Equity Incentive Plan that cease to be subject to
such option for any reason other than exercise of such option; (b) are subject
to an award granted under restricted stock purchase agreements entered into
prior to the effective date of the 1997 Equity Incentive Plan with employees,
officers, directors, consultants, independent contractors or advisors of the
Company, the 1996 Plans, or the 1997 Equity Incentive Plan, that are forfeited
or are repurchased by the Company at the original issue price; or (c) are
subject to any other award granted under the 1996 Plans or under the 1997
Equity Incentive Plan that otherwise terminates without shares being issued,
will again be available for grant and issuance under the 1997 Equity Incentive
Plan. In addition, on August 1, 1997, the number of shares reserved for
issuance under the 1997 Equity Incentive Plan will automatically increase by
4,200,000 shares. The 1997 Equity Incentive Plan will become effective on the
effective date of the Registration Statement for this offering and will serve
as the successor to the 1996 Plans. The 1997 Equity Incentive Plan will
terminate in May 2007, unless sooner terminated by the Board. The 1997 Equity
Incentive Plan authorizes the award of options, restricted stock and stock
bonuses (each an "Award"). No person will be eligible to receive more than
1,000,000 shares in any calendar year pursuant to Awards under the 1997 Equity
Incentive Plan other than a new employee of the Company, who will be eligible
to receive no more than 2,000,000 shares in the calendar year in which such
employee commences employment. The 1997 Equity Incentive Plan is administered
by a committee appointed by the Board, currently the Compensation Committee,
which presently consists of Messrs. Doerr and Ravenel, both of whom are non-
employee directors under applicable federal securities laws and "outside
directors" as defined under applicable federal tax laws. The committee has the
authority to construe and interpret the 1997 Equity Incentive Plan and any
agreement made thereunder, grant Awards and make all other determinations
necessary or advisable for the administration of the 1997 Equity Incentive
Plan.     
   
  The 1997 Equity Incentive Plan provides for the grant of both incentive
stock options ("ISOs") that qualify under Section 422 of the Code and
nonqualified stock options ("NQSOs"). ISOs may be granted only to employees of
the Company or of a parent or subsidiary of the Company. NQSOs may be granted
to employees, officers, directors, consultants, independent contractors and
advisors of the Company or any parent or subsidiary of the Company, provided
such consultants, independent contractors and advisors render bona fide
services not in connection with the offer and sale of securities in a capital-
raising transaction ("Eligible Service Providers"). The exercise price of ISOs
must be at least equal to the fair market value of the Company's Series A
Common Stock on the date of grant. (The exercise price of ISOs granted to 10%
stockholders must be at least equal to 110% of that value.) The exercise price
of NQSOs must be at least equal to 85% of the fair market value of the
Company's Series A Common Stock on the date of grant. The maximum term of
options granted under the 1997 Equity Incentive Plan is ten years. Options
granted under the 1997 Equity Incentive Plan may not be transferred in any
manner other than by will or by the laws of descent and distribution and may
be exercised during the lifetime of the optionee only by the optionee. Options
granted under the 1997 Equity Incentive Plan generally expire three months
after the termination of the optionee's service to the Company or a parent or
subsidiary of the Company, except in the case of death or disability, in which
case the options generally may be exercised up to 12 months following the date
of death or termination of service. Options will generally terminate one month
after termination for cause.

  Opportunities to purchase shares of the Company's Series A Common Stock
("Restricted Stock Awards"), and awards of shares of the Company's Series A
Common Stock ("Stock Bonuses"), either of which may be subject to a right of
repurchase in favor of the Company or other restrictions on ownership or
transfer, may be given to Eligible Service Providers. The administrator of the
1997 Equity Incentive Plan has the authority to determine the restrictions
applied to the stock. The sum of (i) Restricted Stock Awards, (ii) Stock
Bonuses and (iii) options with an exercise or purchase price below fair market
value issued under the 1997 Equity Incentive Plan may not exceed 20% of the
total number of shares reserved for issuance under the 1997 Equity Incentive
Plan as of any date.
   
  If the Company is acquired under certain circumstances, any or all
outstanding Awards may be assumed or replaced by the successor corporation. If
Awards are not assumed or replaced, the vesting of such Awards will accelerate
and all outstanding options will become exercisable in full prior to the
consummation of the transaction. Any options not exercised prior to the
transaction will expire.     
   
  1997 Employee Stock Purchase Plan. In May 1997, the Board adopted and in
June 1997 the stockholders approved the 1997 Employee Stock Purchase Plan (the
"Purchase Plan") and reserved a total of 400,000 shares of the Company's
Series A Common Stock for issuance thereunder. The Purchase Plan will become
effective upon the effective date of the Registration Statement for this
offering and will permit eligible employees to acquire shares of the Company's
Series A Common Stock through payroll deductions. Eligible employees may
select a rate of payroll deduction between 2% and 10% of their compensation
and are subject to certain maximum purchase limitations described in the
Purchase Plan. Except for the first offering, each offering under the Purchase
Plan will be for a period of 24 months (the "Offering Period") and will
consist of four six-month purchase periods (each a "Purchase Period"). The
first Offering Period is expected to begin on the first business day following
the effective date of this Registration Statement and, depending on the
effective date of this Registration Statement, may be greater or less than 24
months long. Offering Periods thereafter will begin on February 15 and August
15. The purchase price for the Company's Series A Common Stock purchased under
the Purchase Plan is 85% of the lesser of the fair market value of the
Company's Series A Common Stock on the first day of the applicable Offering
Period and the last day of the applicable Purchase Period. The Compensation
Committee has the power to change the duration of Offering Periods and
Purchase Periods without stockholder approval, if such change is announced at
least 15 days prior to the beginning of the Offering or Purchase Period to be
affected. The Purchase Plan is intended to qualify as an "employee stock
purchase plan" under Section 423 of the Code.     
   
  401(k) Plan. The Board maintains the @Home 401(k) Plan (the "401(k) Plan"),
a defined contribution plan intended to qualify under Section 401 of the Code.
All employees who are at least 21 years old and have been employed by the
Company for one month are eligible to participate in the 401(k) Plan. An
eligible employee of the Company may begin to participate in the 401(k) Plan
on the first day of January, April, July or October of the 401(k) Plan year
coinciding with or following the date on which such employee meets the
eligibility requirements. A participating employee may make pre-tax
contributions of a percentage (not less than 2% and not more than 20%) of his
or her eligible compensation and up to 100% of any cash bonus, subject to
limitations under the federal tax laws. Employee contributions and the
investment earnings thereon are fully vested at all times. The Company does
not make matching or profit-sharing contributions.     
 
EMPLOYMENT AGREEMENT
   
  On July 31, 1996, the Board elected Thomas A. Jermoluk as President, Chief
Executive Officer and Chairman of the Board of the Company pursuant to an
employment agreement dated July 19, 1996. Under the employment agreement, the
Company has agreed to pay Mr. Jermoluk an annual base salary of $500,000 per
year, and Mr. Jermoluk is eligible to receive a bonus of $200,000 per year
based on the performance of the Company with respect to its annual operating
plan. On July 31, 1996, the Company sold to Mr. Jermoluk a total of 3,000,000
shares of the Company's Series A Common Stock at a purchase price of $.05 per
share for a total of $150,000 and a total of 50,000 shares of the Company's
Series K Preferred Stock at a purchase price of $10.00 per share for a total
of $500,000. Of these shares, 25% were immediately vested on July 22, 1996,
and an     
 
                                      61
<PAGE>
 
   
additional 2.08% will vest on August 22, 1997 and each subsequent month of Mr.
Jermoluk's continuous employment. The Series K Preferred Stock will be
converted upon the closing of this offering into 1,000,000 shares of Series K
Common Stock. Under the terms of Mr. Jermoluk's employment agreement, so long
as Mr. Jermoluk is employed by the Company, and for 90 days thereafter if his
employment is terminated without cause, to the extent that Mr. Jermoluk sells
any of his vested shares during the five-year period beginning on July 22,
2000 at an average price less than $5.00 per share, the Company is obligated
to pay Mr. Jermoluk the excess of $5.00 per share over such average price for
each share sold. The Company must repurchase any unvested shares at
Mr. Jermoluk's cost upon the termination of his employment. If the Company
terminates Mr. Jermoluk's employment without cause, the Company will be
obligated to pay Mr. Jermoluk's base salary and bonus for six months after the
date of such termination, and the Company's right to repurchase any unvested
shares will lapse at the date of such termination.     
 
INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF
LIABILITY
 
  The Company's Certificate of Incorporation includes a provision that
eliminates, to the fullest extent permitted by the Delaware General
Corporation Law (the "Delaware Law"), the personal liability of its directors
for monetary damages for breach of fiduciary duty as a director.
 
  As permitted by Section 145 of the Delaware Law, the Company's Certificate
of Incorporation provides that (i) the Company is required to indemnify its
directors and officers to the fullest extent permitted by the Delaware Law,
(ii) the Company is required to advance expenses, as incurred, to its
directors and officers in connection with a legal proceeding after receipt of
an undertaking by such directors or officers to repay all amounts to which
they are ultimately determined not to be entitled, (iii) to the extent that
the Company is obligated to indemnify a person who is serving at its request
as a director, officer, employee or agent of another entity, the Company's
obligation will be reduced by any amount the indemnitee collects from such
other entity and (iv) the rights conferred in the Company's Certificate of
Incorporation are not exclusive.
   
  The Company has entered into Indemnification Agreements with each of its
current directors and intends to enter into such Indemnification Agreements
with each of its executive officers to give such directors and officers
additional contractual assurances regarding the scope of the indemnification
set forth in the Company's Certificate of Incorporation and to provide
additional procedural protections. At present, there is no pending litigation
or proceeding involving a director, officer or employee of the Company for
which indemnification is sought, nor is the Company aware of any threatened
litigation that may result in claims for indemnification.

  In connection with the Series C Preferred Stock financing, the Company
entered into agreements with Rogers and Shaw granting them exclusive rights to
distribute the @Home service in Canada under the "Wave@Home" brand and the
right to license other cable companies to distribute the service in Canada. In
addition, on April 11, 1997, the Company granted to Rogers and Shaw
transferable warrants to purchase up to an aggregate of 100,000 shares of
Series C Preferred Stock each at a purchase price of $200 per share (which
warrants will be converted into the right to purchase up to an aggregate of
2,000,000 shares of Series A Common Stock at the lower of $10.00 or the
initial public offering price per share following this offering). These
warrants become fully exercisable on the earlier of April 11, 2004 or the
achievement of certain performance milestones with respect to the distribution
of the Wave@Home service in Canada.     
 
  Pursuant to a Voting Agreement entered into with Rogers and Shaw on April
11, 1997, TCI, Comcast and Cox have agreed (i) to use their reasonable best
efforts to cause a single representative designated jointly by Rogers and Shaw
to be nominated for election to the Board and an additional representative
designated jointly by Rogers and Shaw to be afforded the right to attend all
meetings of the Board as a nonvoting observer and (ii) to vote all voting
securities of the Company controlled by them in favor of election of the
designee of Rogers and Shaw to the Board. The Voting Agreement will terminate
on the earlier to occur of the date that (i) neither Rogers nor Shaw continues
to offer the Wave@Home service on an exclusive basis or (ii) Rogers and Shaw
together with their controlled affiliates cease to own at least 2,000,000
shares of Series A Common Stock plus either an additional 500,000 shares of
Series A Common Stock or warrants to purchase an additional 500,000 shares of
Series A Common Stock.
   
  Stockholders' Agreement. On August 1, 1996, TCI, Comcast, Cox and the KPCB
Purchasers (collectively, the "Principal Stockholders") and the Company
entered into a Stockholders' Agreement, which they have agreed to amend upon
the closing of this offering (as amended, the "Stockholders' Agreement"),
which provides for certain voting agreements, restrictions on transfer of
Company securities, rights of first offer, tag-along and drag-along rights and
preemptive rights. The following summary description of the Stockholders'
Agreement does not purport to be complete and is qualified in its entirety by
reference to the text of the Stockholders' Agreement as it will be amended
immediately before the closing of this offering, which is filed as an exhibit
to the Registration Statement of which this Prospectus forms a part.
Furthermore, there can be no assurance that following the consummation of this
offering the parties will not cause the Stockholders' Agreement to be amended,
modified or terminated or cause the Company to waive any provision of the
Stockholders' Agreement.     
   
  The Stockholders' Agreement provides that each Principal Stockholder will
vote all of its shares of Company voting stock in favor of any action required
by the Stockholders' Agreement, including the election of the Chief Executive
Officer of the Company to its Board, and that any holder of Series B Common
Stock (all of which is currently owned by TCI) will vote all such shares in
favor of the election of certain designees of TCI, Comcast and Cox to the
Board as Series B Common Stock Directors as follows: Comcast will be entitled
to designate one director so long as it owns at least 5,000,000 shares of
Common Stock; Cox will be entitled to designate one director so long as it
owns at least 5,000,000 shares of Common Stock; and TCI will be entitled to
designate three directors so long as it owns at least 7,700,000 shares of
Series B Common Stock, two directors so long as it owns at least 6,350,000
shares of Series B Common Stock and one director so long as it owns at least
5,000,000 shares of Series B Common Stock. See "Risk Factors--Control by TCI;
Veto Power of Other Principal Stockholders."     
   
  The Stockholders' Agreement, with certain exceptions, restricts transfers of
Company securities by the Principal Stockholders until the earliest to occur
of (i) June 4, 2006, (ii) the fifth anniversary of the termination of the
exclusive period applicable to any Principal Cable Stockholder and (iii) the
sixth anniversary of this offering. To the extent transfers of Series B and K
Common Stock are permitted, the holders of such shares generally must convert
them to Series A Common Stock prior to consummating such transfers. Following
the first anniversary of this offering, each Principal Stockholder will be
permitted to sell its Series A Common Stock in the public market if it first
offers to each other Principal Stockholder the right of first offer to
purchase such securities. Following the closing of this offering, the
restrictions on transfer contained in the Stockholders' Agreement will not
apply to any constituent partner of KPCB. The restrictions on transfer do not
apply to a     
 
                                      64
<PAGE>
 
   
transfer of Company securities that would result in an unaffiliated third
party acquiring a majority of the voting stock of the Company (a "Control
Block Sale"). In the event of a Control Block Sale, all Principal Stockholders
that continue to own at least 25% of the Company securities they originally
purchased on or before August 1, 1996 (the "Eligible Principal Stockholders")
will be permitted to participate in the Control Block Sale by selling a pro
rata portion of their Company securities to the third party (the "Tag-Along
Right"). If any group of Principal Stockholders consisting of TCI and any two
other Eligible Principal Stockholders proposes to make a Control Block Sale,
that group will have the right to require the other Principal Stockholders to
sell a pro rata portion of their Company securities to the third party in the
Control Block Sale (the "Drag-Along Right").     
   
  The Stockholders' Agreement provides that, if the number of homes passed by
a Principal Cable Stockholder's cable systems that remain subject to the
exclusivity provisions of the Master Distribution Agreement (together with any
systems that have been released from such provisions due to the Company's
failure to meet the rollout schedule) falls below 80% of the Principal Cable
Stockholder's base homes passed as of June 4, 1996, then such Principal Cable
Stockholder must offer to sell a proportionate amount of its Company
securities to the other Principal Stockholders at a price equal to the average
closing price of the Company's Series A Common Stock over the most recent 20
trading days preceding the event.     
 
  The Stockholders' Agreement gives each Eligible Principal Stockholder the
preemptive right to purchase a pro rata portion of any new securities offered
by the Company other than securities issued pursuant to a public offering,
securities issued pursuant to any incentive plan or agreement for the benefit
of the Company's employees, directors or consultants, securities issued by the
Company in connection with an acquisition, and securities issued in exchange
for interests in a joint venture or other business combination.
 
  The Stockholders' Agreement will terminate on the earliest of (i) June 4,
2021, (ii) when there are no Eligible Principal Stockholders and no Principal
Cable Stockholders subject to exclusivity obligations under the Master
Distribution Agreement, (iii) a merger in which the Company is not the
surviving entity or (iv) when there are no shares of Common Stock or Preferred
Stock of the Company outstanding.
 
  Registration Rights Agreement. All of the current holders of Preferred Stock
have certain registration rights with respect to their shares of Series A
Common Stock following this offering. See "Description of Capital Stock--
Registration Rights."
   
  Officer Loans. In connection with the exercise of stock options granted
under the Second 1996 Plan, the Company permitted two executive officers,
Donald P. Hutchison and John L. O'Farrell, to purchase shares of Series A
Common Stock in exchange for promissory notes in the amounts of $96,000 and
$66,000, respectively. Each note is secured by the shares purchased with that
note. The notes bear interest at the rates of 6.31% and 6.42%, respectively,
and are due and payable on March 15, 2002 and April 28, 2002, respectively.
The Company has approved loans to Messrs. Hutchison and O'Farrell of $100,000
and $200,000, respectively, to assist each of them in the purchase of a home.
The loans will be secured by the homes purchased by Messrs. Hutchison and
O'Farrell, respectively. The loans, which have not yet been issued, will have
a five-year term and bear interest at the minimum rate sufficient to avoid
imputation of taxable income.     
 
CERTAIN BUSINESS RELATIONSHIPS
   
  Master Distribution Agreement with TCI, Comcast and Cox. The Company and its
Principal Cable Stockholders (TCI, Comcast and Cox) are parties to the Master
Distribution Agreement. The following summary description of the Master
Distribution Agreement does not purport to be complete and is qualified in its
entirety by reference to the text of the Master Distribution Agreement, which
is filed as an exhibit to the Registration Statement of which this Prospectus
forms a part. Furthermore, there can be no assurance that following the
consummation of this offering the parties will not cause the Master
Distribution Agreement to be amended, modified or terminated or cause the
Company to waive any provision of the Master Distribution Agreement.     
 
 
                                      65
<PAGE>
 
   
  Under the terms of the Master Distribution Agreement, in connection with the
Company's periodic budgets and business plans, the parties have agreed to
cooperate in good faith to establish a master rollout schedule for the
deployment of the @Home service within the cable system territories of the
respective Principal Cable Stockholders, and the Company is obligated to use
commercially reasonable efforts to cause the @Home service to be made
available to the qualifying upgraded homes passed of the Principal Cable
Stockholders on a substantially pro rata basis in accordance with the master
roll-out schedule. While the Master Distribution Agreement provides that the
Principal Cable Stockholders will be subject to certain exclusivity
obligations described below, there is no affirmative obligation on the part of
the Principal Cable Stockholders to upgrade their cable plants to two-way HFC
cable or to offer the @Home service over their cable systems. The Master
Distribution Agreement contemplates that the Company will enter into
agreements ("LCO Agreements") with the Affiliated LCOs of the Principal Cable
Stockholders for the distribution of the @Home service, although no LCO
Agreements have been executed to date. The Company and the Principal Cable
Stockholders have established the principal terms of the LCO Agreements,
including the payment to the Company of 35% of the basic and premium service
revenue received by Affiliated LCOs from subscribers to the @Home service.
There can be no assurance that following the consummation of this offering the
parties will not cause the LCO Agreements to be amended, modified or
terminated or cause the Company to waive any provision of the LCO Agreements.
       
  Until June 4, 2002 or such earlier time as the exclusivity provisions
described below terminate as to a Principal Cable Stockholder (the "Restricted
Period"), each Principal Cable Stockholder on behalf of itself and its
controlled affiliates has agreed not to conduct, participate in or have a
material beneficial ownership interest in any business within the United
States (a "Restricted Business") that involves (i) the provision of a
residential Internet service over the cable television plant of the Principal
Cable Stockholder at data transmission speeds greater than 128 Kbps and whose
primary purpose is the provision to consumers of entertainment, information
content, transactional services or electronic mail, chat and news groups (a
"Consumer Purpose"), (ii) the connection by the Principal Cable Stockholder of
its cable television plant directly or indirectly to any Internet backbone for
a Consumer Purpose at data transmission speeds greater than 128 Kbps or (iii)
the provision of an Internet backbone service. These exclusivity provisions do
not apply to the creation or aggregation of content or, among other things,
the following Excluded Services: (i) the provision of telephony services, (ii)
the provision of services that are primarily work-related such as the @Work
services, (iii) the provision of Internet services that do not use the cable
television infrastructures of the Principal Cable Stockholders, (iv) the
provision of any local Internet service that does not require use of an
Internet backbone outside a single metropolitan area, (v) the provision of
services that are utilized primarily to connect students to schools, colleges
or universities, (vi) the provision of Internet telephony, Internet video
telephony or Internet video conferencing, (vii) the provision of certain
limited Internet services for display on a television, (viii) the provision of
certain Internet services that are primarily downstream services where the
user cannot send upstream commands in "real-time," as referenced in the Master
Distribution Agreement, (ix) the provision of streaming video transmissions
that include video segments longer than ten minutes in duration or (x) limited
testing, trials and similar activities of less than six months.     
   
  The exclusivity provisions described in the preceding paragraph may be
terminated under the following circumstances: (i) any Affiliated LCO may
terminate its exclusivity obligations if the Company fails to roll out the
@Home service in such operator's territory by mutually agreed dates in a
schedule set forth in an LCO Agreement; (ii) the Principal Cable Stockholders
may terminate all exclusivity obligations upon a change in law that materially
impairs certain of the Principal Cable Stockholders' rights under the Master
Distribution Agreement; (iii) Comcast or Cox may terminate all Principal Cable
Stockholders' exclusivity obligations if there is a change of control of TCI
at any time or if certain subscriber penetration levels for the @Home services
are not achieved by TCI and its affiliates on June 4, 1999 or any anniversary
thereof; and (iv) Comcast may terminate its exclusivity obligations at its
election after June 4, 1999 if it permits a portion of its equity in the
Company to be repurchased by the Company at Comcast's original cost. Comcast
has informed the Company that Comcast has entered into an agreement with
Microsoft pursuant to which Microsoft can require Comcast to terminate its
    
                                      66
<PAGE>
 
   
exclusivity obligations after June 4, 1999. Although Microsoft has stated in
the agreement that it has no present intention to do so, there can be no
assurance that Microsoft will not be more likely than Comcast to terminate
Comcast's exclusivity obligations.     
   
  Until the later of (i) such time as the applicable Principal Cable
Stockholder ceases to be obligated under the exclusivity provisions set forth
above or (ii) if the exclusivity provisions are terminated by reason of TCI's
failure to meet specified subscriber penetration requirements, June 4, 2002,
the Company has agreed (a) not to offer or provide Internet services at data
transmission speeds greater than 128 Kbps to residences in the geographic area
served by the cable systems of a Principal Cable Stockholder that remains in
compliance with the exclusivity provisions without regard to whether the
Restricted Period has ended as to such Principal Cable Stockholder (the
"Exclusive Territory") and (b) not to offer, provide, distribute, advertise,
promote or market (or carry or otherwise distribute advertising or promotions
with respect to) any streaming video transmissions that include video segments
longer than ten minutes in duration or any other Internet service that is not
a Restricted Business to residences in the Exclusive Territory of a Principal
Cable Stockholder without its prior written consent.     
 
  In addition, the Company has agreed that it will not offer, provide,
distribute, advertise, promote or market any streaming video transmissions
that include video segments longer than ten minutes in duration in any "area
of dominant influence" as defined by the FCC ("ADI") that includes an
Exclusive Territory of a Principal Cable Stockholder without the prior consent
of the affected Principal Cable Stockholders having two-thirds of the cable
television subscribers of all Principal Cable Stockholders having an Exclusive
Territory in the ADI.
   
  The Company's agreements with its Principal Cable Stockholders do not
require that such Principal Cable Stockholders maintain a specified number of
cable systems, subscribers or homes passed by cable infrastructure in order to
maintain their control over and equity ownership of the Company. However, the
Stockholders' Agreement does provide that if a Principal Cable Stockholder's
number of homes passed that remain subject to certain exclusivity provisions
decreases by more than 20% of the number of homes passed as of June 4, 1996
(subject to certain exceptions), then such Principal Cable Stockholder must
offer to sell a proportionate amount of its equity interest in the Company to
the other Principal Cable Stockholders at the fair market value thereof.
However, such provisions would permit the disposition of a portion of such
Principal Cable Stockholders' cable assets without imposing any penalty and,
in the event a Principal Cable Stockholder exceeds the 20% threshold, selling
shares at fair market value may not constitute a significant penalty to such
Principal Cable Stockholder. Therefore, there can be no assurance that such
arrangements will effectively discourage a Principal Cable Stockholder from
disposing of a significant amount of its cable systems without requiring that
such cable systems remain subject to such exclusivity provisions. TCI has
recently announced the proposed sale to Cablevision Systems Corporation of 10
cable systems in New York and New Jersey, and to Adelphia of certain cable
systems in Buffalo, N.Y. The cable systems proposed to be transferred in these
transactions have approximately 1.1 million and 260,000 homes passed,
respectively. In addition, TCI has announced that it is considering various
plans and proposals that may result in the disposition of other of its cable
systems. To the extent that the terms of any such transactions require that
such systems remain subject to such exclusivity provisions, such cable systems
and their homes passed would continue to be included in TCI's homes passed for
purposes of determining whether or not TCI is obligated to offer a portion of
its equity interest in the Company to the other Principal Cable Stockholders,
even though such cable systems are no longer owned or controlled by TCI. To
the extent that the Principal Cable Stockholders dispose of cable systems in
the future without causing such cable systems to remain subject to such
exclusivity provisions, the number of homes passed that are exclusive to the
Company will be decreased. Such decreases in the number of exclusive homes
passed may have an adverse effect upon the business, operating results and
financial condition of the Company.     
       
  Each Principal Cable Stockholder and its controlled affiliates are entitled
to "most favored nation" ("MFN") terms and conditions of carriage with respect
to the distribution of the Company's services and with respect to the terms
and conditions of any related trademark license agreement or ancillary
services arrangements, including all direct and indirect benefits as a result
of a transaction with the Company that are no less favorable than those
offered to any other cable operator individually or collectively from time to
time. This MFN provision
 
                                      67
<PAGE>
 
requires identical treatment of the Principal Cable Stockholders and their
controlled affiliates without regard to size or identity with respect to each
other and with respect to the terms and conditions provided to unaffiliated
third parties (except as to exclusivity and certain other terms applicable to
third parties).
   
  The Principal Cable Stockholders and their affiliates are entitled to
create, author, promote and otherwise engage in the business of local content
offerings, and will retain all revenue from such local content offerings and
associated advertising within the designated local area of the @Home service's
home page. The Company is responsible for the aggregation and promotion of
national content offerings as part of the @Home service and will retain all
revenues from associated advertising within the designated national area of
the @Home service's home page and Web site. Each Principal Cable Stockholder
has the right to exclude the promotion of specified national content providers
from the @Home service offered through such Principal Cable Stockholder's
cable systems, subject to an adjustment in the split of premium service
revenues between the Principal Cable Stockholder and the Company if the number
of specified exclusions exceeds certain limits. In addition, a Principal Cable
Stockholder has the right to block access to content that (i) includes
streaming video segments of more than ten minutes in duration, (ii) is
pornographic or overly violent or (iii) could adversely affect a cable
operator's franchise to deliver cable television service or the @Home service,
and the Company is obligated to use its best efforts to block such access.
       
  The Company is obligated to use reasonable best efforts to consult with and
involve each of the Principal Cable Stockholders in the development of
requirements for and design of enhancements, new features and new applications
of the @Home service and coordinate with respect to the introduction of such
enhancements, features and applications that could have a significant effect
on the cable operations of a Principal Cable Stockholder with respect to its
delivery of the @Home service to its customers. If Principal Cable
Stockholders representing a majority of the residential subscribers of the
@Home service object to such enhancement, feature or application, the Company
has agreed not to implement such enhancement, feature or application in the
territories of objecting Principal Cable Stockholders.     
 
  Services Provided by Affiliates of Principal Stockholders. During 1995, KPCB
advanced $210,000 of general and administrative expenses to the Company. The
Company repaid $117,000 of these advances in 1995 and the remainder in 1996.
During 1995, the Company made expense-sharing payments in the amount of
$109,000 to an affiliate of TCI. During 1995 and 1996, the Company contracted
for development and system integration of back office systems in the amounts
of $291,000 and $2,631,000, respectively, from a company in which TCI has a
30% ownership interest. During 1995 and 1996, the Company contracted for
$123,000 and $77,000, respectively, of prototype development for the @Home
user interface from a company owned by TCI.
 
  Agreement with Rogers and Shaw. In March 1997, in connection with the equity
investment in the Company by Rogers and Shaw, the Company, Rogers and Shaw
entered into an agreement for the distribution by Rogers and Shaw in Canada of
a localized version of the @Home service referred to as "Wave@Home." The
Company has granted Rogers and Shaw the exclusive rights for an initial period
of six years, subject to achievement of certain performance milestones, to
distribute, market and promote the service in Canada either directly in
jurisdictions where they are licensed to operate cable systems or indirectly
through the sublicensing of other cable operators in Canada. During the term
of the exclusivity of such licenses, Rogers and Shaw have each agreed, subject
to the same exceptions to exclusivity available to the Principal Cable
Stockholders, not to market, promote or control any other residential Internet
service (other than dial-up services at data transmission speeds of 128 Kbps
or less). However, Rogers and Shaw are not precluded from distributing other
residential Internet Services. Rogers and Shaw will be responsible, among
other things, for (i) upgrading their cable systems for two-way data
transmission services, (ii) providing the necessary cable data routers and
cable modems, (iii) providing the telecommunications systems necessary to
connect their subscribers to cable headends or fiber nodes, to connect such
headends or fiber nodes to the Company's RDCs in Canada and to connect such
RDCs to the nearest points of presence of the @Home backbone in the United
States, (iv) providing customer installation, billing, customer service and
technical support, (v) providing the Company with space to co-locate its RDCs
and related equipment within Rogers' and Shaw's network distribution
facilities, (vi) providing necessary
 
                                      68
<PAGE>
 
modifications to billing, subscriber and network management systems to
interface with the Company, (vii) distributing and promoting the Wave@Home
Service and (viii) programming local content and customizing certain national
content for the Canadian market.
 
  The Company will be responsible under the Agreement, among other things,
for: (i) treating Rogers and Shaw with a priority equal to TCI, Comcast and
Cox in matters of deployment, (ii) granting Rogers and Shaw access to the
Company's broadband networks, (iii) installing and maintaining an optimal
number of RDCs and providing the same level of performance received by the

Comcast and Cox collectively hold a majority of the voting stock, entered into
a Master Communications Services Agreement, with an initial term of five
years, under which TCG has agreed to provide the Company with facilities
management and telecommunications network services for the local
telecommunications transport requirements of the Company's services. TCG is
the largest CLEC in the United States, providing high-speed fiber optic

facilities. The agreement provides the Company with such telecommunications
services at rates generally at or below those of competing carriers, and the
ability to co-locate the Company's RDCs within TCG's network distribution

                         DESCRIPTION OF CAPITAL STOCK
   
  As of April 11, 1997, assuming the conversion of all outstanding shares of
Preferred Stock into shares of Common Stock, there were outstanding 79,525,927
shares of Series A Common Stock held of record by approximately 254
stockholders, 15,400,000 shares of Series B Common Stock held of record by one
stockholder, 14,877,660 shares of Series K Common Stock held of record by five
stockholders, options to purchase 939,250 shares of Series A Common Stock and
warrants to purchase 2,200,000 shares of Series A Common Stock.     
 
  The following summary of certain provisions of the Common Stock and
Preferred Stock does not purport to be complete and is subject to, and
qualified in its entirety by, the provisions of the Company's Certificate of
Incorporation, which is included as an exhibit to the Registration Statement,
of which this Prospectus forms a part, and by the provisions of applicable
law.
 
COMMON STOCK
 
  The Company is authorized to issue 230,277,660 shares of Common Stock, $.01
par value, of which 200,000,000 have been designated Series A Common Stock,
15,400,000 have been designated Series B Common Stock and 14,877,660 have been
designated Series K Common Stock. Subject to preferences that may be
applicable to any Preferred Stock outstanding at the time, the holders of
outstanding shares of Common Stock are entitled to receive dividends out of
assets legally available therefor at such times and in such amounts as the
Board may from time to time determine. Holders of Series A Common Stock and
Series K Common Stock are entitled to one vote for each share held, and
holders of Series B Common Stock are entitled to ten votes for each
 
                                      71
<PAGE>
 
   
share held, on all matters presented to stockholders. The Series A Common
Stock is the only series of Common Stock that is registered in this offering.
Each share of Series B Common Stock and Series K Common Stock is convertible,
at the option of the holder, into one share of Series A Common Stock. Shares
of Series A Common Stock are not convertible into shares of Series B or Series
K Common Stock. All other rights and privileges are equal with respect to
holders of Series A, B and K Common Stock, except that, so long as there are
at least 5,000,000 shares of Series B Common Stock outstanding, the holders of
Series B Common Stock (all of which will be owned by a subsidiary of TCI
following the offering), voting separately as a single series, have the right
to elect five directors to the Board; so long as there are at least 5,000,000
shares of Series K Common Stock outstanding (the substantial majority of which
will be controlled by KPCB following the offering), the holders of Series K
Common Stock, voting separately as a single series, have the right to elect
one director to the Board; so long as the holders of Series B Common Stock or
Series K Common Stock are entitled to elect any Series B Common Stock Director
or any Series K Common Stock Director, the holders of Series A Common Stock,
voting separately as a single series, have the right to elect two directors
who are not officers (other than any Vice Chairman) or employees of the
Company and are not affiliates or associates of TCI, Comcast or Cox. The
Common Stock is not entitled to preemptive rights and is not subject to
redemption. Upon liquidation, dissolution or winding-up of the Company, the
assets legally available for distribution to stockholders are distributable
ratably among the holders of the Common Stock and any participating Preferred
Stock outstanding at that time after payment of liquidation preferences, if
any, on any outstanding Preferred Stock and payment of other claims of
creditors. Each outstanding share of Common Stock is, and all shares of Common
Stock to be outstanding upon completion of this offering will be, duly and
validly issued, fully paid and nonassessable. See "Management--Board
Composition and Procedures."     
 
PREFERRED STOCK
 
  Upon the closing of this offering, all outstanding shares of Preferred Stock
will be converted into shares of Common Stock at a conversion rate of 20
shares of the applicable series of Common Stock for each share of Preferred
Stock. The Preferred Stock so converted will be retired and may not be
reissued. See Notes 5 and 10 of Notes to Financial Statements for a
description of the Preferred Stock. The Board is authorized, subject to any
limitation prescribed by Delaware law, to issue, from time to time, in one or
more series, up to 9,650,000 additional shares of Preferred Stock, with such
designations, preferences and relative, participating, optional or other
special rights, and qualifications, limitations or restrictions thereof, as
shall be stated and expressed in a Board resolution or resolutions providing
for the issue of such series without any further vote or action by the
stockholders. The Board may authorize the issuance of such Preferred Stock
with voting or conversion rights that could adversely affect the voting power
or other rights of the holders of Common Stock. Thus, the issuance of
Preferred Stock may have the effect of delaying, deferring or preventing a
change in control of the Company. The Company has no current plan to issue any
shares of Preferred Stock.
 
REGISTRATION RIGHTS
   
  Following this offering, the holders of approximately 96,452,260 shares of
Series A Common Stock issuable upon conversion of the Preferred Stock (and
other series of Common Stock) and holders of warrants to purchase a total of
2,200,000 shares of Series A Common Stock will have certain rights to cause
the Company to register those shares (the "Registrable Shares") under the
Securities Act at any time after the first anniversary of the closing date of
this offering. Thereafter, the Company may be required to effect up to four
registrations requested by the TCI stockholder group, two registrations
requested by the Comcast stockholder group, two registrations requested by the
Cox stockholder group, two registrations requested by the KPCB stockholder
group and two registrations requested by the persons who held Series C
Preferred Stock and warrants to purchase Series C Preferred Stock prior to
this offering. Stockholder groups not part of the initial registration demand
are entitled to notice of such registration and are entitled to include shares
of Registrable Securities therein. These registration rights are subject to
certain conditions and limitations, including (i) the right, under certain
circumstances, of the underwriters of an offering to limit the number of
shares included in such registration and (ii) the right of the Company to
delay the filing of a registration statement for not more than 120 days after
receiving the registration demand. Notwithstanding the foregoing, the exercise
of the Principal Stockholders'     
 
                                      72
<PAGE>
 
registration rights are subject to the other Principal Stockholders' rights of
first offer as set forth in the Stockholders' Agreement, unless specifically
exempted therefrom. If any stockholder group requests registration of at least
500,000 Registrable Shares, the Company is obligated to pay all registration
expenses incurred in connection with such registration (other than
underwriters' discounts and commissions and stock transfer fees or expenses)
and the fees and expenses of a single counsel to the selling stockholders.
These demand registration rights expire with respect to the Series C Preferred
stockholder group upon the fifth anniversary of the closing of this offering.
 
  In addition, if the Company proposes to register any of its equity
securities under the Securities Act, whether or not for sale for its own
account, other than in connection with a Company employee benefit plan or a
corporate reorganization, the holders of Registrable Shares are entitled to
notice of such registration and are entitled to include Registrable Shares
therein. These rights are subject to certain conditions and limitations,
including the right of the underwriters of an offering to limit the number of
shares included in such registration under certain circumstances and the right
of the Company to delay or withdraw any such registration. The Company is
obligated to pay all registration expenses incurred in connection with such
registration other than underwriters' discounts and commissions, stock
transfer fees or expenses, the pro rata share of the incremental filing fee
under the Securities Act attributable to the applicable Registrable Shares and
the fees and disbursements of counsel to the holders of the Registrable
Shares. These "piggyback" registration rights expire with respect to the
Series C Preferred stockholder group upon the fifth anniversary of the closing
of this offering.
 
DELAWARE TAKEOVER STATUTE
   
  The Company is not subject to Section 203 of the Delaware Law, which,
subject to certain exceptions, prohibits a Delaware corporation from engaging
in any business combination with any interested stockholder for a period of
three years following the date that such stockholder became an interested
stockholder. See "Risk Factors--Ability of TCI to Transfer Control of the
Company."     
 
TRANSFER AGENT AND REGISTRAR

                        SHARES ELIGIBLE FOR FUTURE SALE
 
  Prior to this offering, there has been no public market for the Series A
Common Stock of the Company. Future sales of substantial amounts of Series A
Common Stock in the public market could materially and adversely affect
prevailing market prices from time to time. Furthermore, since no shares will
be available for sale shortly after this offering because of certain
contractual and legal restrictions on resale (as described below), sales of
substantial amounts of Series A Common Stock of the Company in the public
market after these restrictions lapse could materially and adversely affect
the prevailing market price and the ability of the Company to raise equity
capital in the future.
   
  Upon completion of this offering, the Company will have outstanding an
aggregate of 117,803,587 shares of Common Stock (based upon shares outstanding
at April 11, 1997), assuming no exercise of the Underwriters' over-allotment
option and no exercise of outstanding options or warrants. Of these shares,
all of the Shares sold in this offering will be freely tradeable without
restriction or further registration under the Securities Act, unless such
shares are purchased by "affiliates" of the Company as that term is defined in
Rule 144 under the Securities Act (the "Affiliates"). The remaining
109,803,587 shares of Common Stock held by existing stockholders are
"restricted securities" as that term is defined in Rule 144 under the
Securities Act ("Restricted Shares"). Restricted Shares may be sold in the
public market only if registered or if they qualify for an exemption from
registration under Rule 144 or 701 promulgated under the Securities Act, which
rules are summarized below. All officers, directors, stockholders and option
and warrant holders of the Company have agreed, subject to     
 
                                      73
<PAGE>
 
   
certain 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, 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 of 180
days after the date of this Prospectus, without the prior written consent of
Morgan Stanley & Co. Incorporated. As a result of the contractual restrictions
described below and the provisions of Rule 144 and 701, the Restricted Shares
will be available for sale in the public market as follows: (i) no shares will
be eligible for immediate sale on the date of this Prospectus;
(ii) 103,803,587 shares will be eligible for sale upon expiration of the lock-
up agreements 180 days after the date of this Prospectus, subject in most
instances to the volume limitations of Rule 144 and subject to certain
restrictions on transfer by the Principal Cable Stockholders set forth in the
Stockholders' Agreement, and (iii) the remaining 6,000,000 shares will become
eligible for sale on April 11, 1998, subject to the volume limitation of Rule
144.     
   
  In general, under Rule 144 as currently in effect, beginning 90 days after
the date of this Prospectus, a person (or persons whose shares are aggregated)
who has beneficially owned Restricted Shares for at least one year (including
the holding period of any prior owner except an Affiliate) would be entitled
to sell within any three-month period a number of shares that does not exceed
the greater of: (i) 1% of the number of shares of Common Stock then
outstanding (which will equal approximately 1,178,000 shares immediately after
this offering); or (ii) 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 certain manner of sale provisions and notice requirements
and to the availability of current public information about the Company. Under
Rule 144(k), a person who is not deemed to have been an Affiliate of the
Company at any time during the 90 days 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 except an Affiliate), is
entitled to sell such shares without complying with the manner of sale, public
information, volume limitation or notice provisions of Rule 144; therefore,
unless otherwise restricted, "144(k) shares" may be sold immediately upon the
completion of this offering. In general, under Rule 701 of the Securities Act
as currently in effect, any employee, consultant or advisor of the Company who
purchases shares from the Company in connection with a compensatory stock or
option plan or other written agreement is eligible to resell such shares 90
days after the effective date of this offering in reliance on Rule 144, but
without compliance with certain restrictions, including the holding period,
contained in Rule 144.     
   
  Upon completion of this offering, the holders of 96,452,260 shares of Series
A Common Stock issuable upon conversion of Preferred Stock (and other series
of Common Stock), and holders of warrants to purchase a total of 2,200,000
shares of Series A Common Stock, or their transferees, will be entitled to
certain rights with respect to the registration of such shares under the
Securities Act. See "Description of Capital Stock--Registration Rights."
Registration of such shares under the Securities Act would result in such
shares becoming freely tradeable without restriction under the Securities Act
(except for share purchases by Affiliates) immediately upon the effectiveness
of such registration.     
   
  The Company intends to file a registration statement under the Securities

  The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the Shares of Series A Common
Stock offered hereby 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 Series A Common Stock offered hereby
(other than those covered by the Underwriters' over-allotment option described
below) if any such shares are taken.     
          
  The Underwriters initially propose to offer part of the Shares of Series A
Common Stock directly to the public at the initial public offering price set
forth on the cover page hereof and part to certain dealers at a price that
represents a concession not in excess of $   a share under the initial public
offering price. The Underwriters may allow, and such dealers may reallow, a
concession not in excess of $   a share to other Underwriters or to certain
dealers.     
   
  Pursuant to the Underwriting Agreement, the Company has granted to the
Underwriters an option, exercisable for 30 days from the date of this
Prospectus, to purchase up to an aggregate of 1,200,000 additional Shares of
Series A Common Stock at the initial public offering price set forth on the
cover page hereof, less underwriting discounts and commissions. The
Underwriters may exercise such option to purchase solely for the purpose of
covering over-allotments, if any, made in connection with the offering of the
Shares of Series A Common Stock offered hereby. To the extent such option is
exercised, each Underwriter will become obligated, subject to certain
conditions, to purchase approximately the same percentage of such additional
Shares of Series A Common Stock as the number set forth next to such
Underwriter's name in the preceding table bears to the total number of shares
of Series A Common Stock set forth next to the names of all Underwriters in
the preceding table.

  See "Shares Eligible for Future Sale" for a description of certain
arrangements by which all officers, directors, stockholders and option holders
of the Company have agreed not to sell or otherwise dispose of Common Stock or
convertible securities of the Company for up to 180 days after the date of
this Prospectus without the prior consent of Morgan Stanley & Co.
Incorporated. The Company has agreed in the Underwriting Agreement that it
will not, directly or indirectly, without the prior written consent of Morgan
Stanley & Co. Incorporated, 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 any shares of Common
Stock or any securities convertible into or exchangeable for Series A Common
Stock, for a period of 180 days after the date of this Prospectus, except
under certain circumstances.     
   
  The Representatives have informed the Company that they do not intend sales
to discretionary accounts to exceed five percent of the total number of Shares
of Series A Common Stock offered by them.     
   
  The Underwriters have reserved for sale, at the initial public offering
price, up to 10% of the Shares of the Series A Common Stock offered hereby
(including Shares subject to the Underwriters' over-allotment option) for
certain individuals who have expressed an interest in purchasing such Shares
of Series A Common Stock in the offering. The number of shares available for
sale to the general public will be reduced to the extent such persons purchase
such reserved shares. Any reserved shares not so purchased will be offered by
the Underwriters to the general public on the same basis as other shares
offered hereby.     
 
  In order to facilitate the offering of the Series A Common Stock, the
Underwriters may engage in transactions that stabilize, maintain or otherwise
affect the price of the Series A Common Stock. Specifically, the Underwriters
may over-allot in connection with the offering, creating a short position in
the Series A Common Stock for their own account. In addition, to cover over-
allotments or to stabilize the price of the Series A Common Stock, the
Underwriters may bid for, and purchase, shares of Series A Common Stock in the
open market. Finally, the underwriting syndicate may reclaim selling
concessions allowed to an Underwriter or a dealer for distributing the Series
A Common Stock in the offering, if the syndicate repurchases previously
distributed Series A 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 Series A 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.
 
  The Company and the Underwriters have agreed to indemnify each other against
certain liabilities, including liabilities under the Securities Act.
 
PRICING OF THE OFFERING
 
  Prior to this offering, there has been no public market for the Series A
Common Stock or any other securities of the Company. The initial public
offering price for the Series A Common Stock will be determined by
negotiations among the Company and the Representatives. Among the factors to
be considered in determining the initial public offering price will be the
future prospects of the Company and its industry in general, sales, earnings
and certain other financial and operating information of the Company in recent
periods, and the price-earnings ratios, price-sales ratios, market prices of
securities and certain financial and operating information of companies
engaged in activities similar to those of the Company. 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.

  The consolidated financial statements of At Home Corporation as of December
31, 1995 and 1996, and for the period from March 28, 1995 (inception) to
December 31, 1995 and the year ended December 31, 1996, appearing in this
Prospectus and Registration Statement have been audited by Ernst & Young LLP,
independent auditors, as set forth in their report appearing elsewhere herein,
and are included in reliance upon such report given upon the authority of such
firm as experts in accounting and auditing.
 
                        CHANGE IN INDEPENDENT AUDITORS
   
  Effective April 1, 1997, the Company selected Ernst & Young LLP as its
principal independent auditors to replace KPMG Peat Marwick LLP, who were
dismissed as auditors of the Company on that date. The decision to change
independent auditors was approved by the Board. In connection with the audit
for the period from March 28, 1995 (inception) to December 31, 1995, and the
subsequent interim periods through April 1, 1997, there were no disagreements
with KPMG Peat Marwick LLP on any matter of accounting principles or
practices, financial statement disclosure or auditing scope or procedures
that, if not resolved to the satisfaction of KPMG Peat Marwick LLP, would have
caused them to make reference to the matter in their report. The former
accountant's report for the period from March 28, 1995 (inception) to December
31, 1995 is not a part of the financial statements of the Company included in
this Prospectus. The report of KPMG Peat Marwick LLP on the consolidated
financial statements of the Company for the period from March 28, 1995
(inception) to December 31, 1995 did not contain any adverse opinion or
disclaimer of opinion and was not qualified or modified as to uncertainty,
audit scope or accounting principles.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Stockholders
At Home Corporation
 
  We have audited the accompanying consolidated balance sheets of At Home
Corporation as of December 31, 1995 and 1996, and the related consolidated
statements of operations, stockholders' equity, and cash flows for the period
from March 28, 1995 (inception) to December 31, 1995 and for the year ended
December 31, 1996. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
  We conducted our audits in accordance with 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 financial statements referred to above present fairly,
in all material respects, the consolidated financial position of At Home
Corporation at December 31, 1995 and 1996, and the consolidated results of its
operations and its cash flows for the period from March 28, 1995 (inception)
to December 31, 1995 and for the year ended December 31, 1996, in conformity
with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
 (INFORMATION FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND 1997 IS UNAUDITED)
 
1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 The Company
 
  At Home Corporation (the "Company") was incorporated in the state of
Delaware on March 28, 1995. The Company provides Internet services to
consumers and businesses over the cable television infrastructure. As of
December 31, 1996, the Company's services were available through cable systems
in a limited number of cities in the United States.
 
 Dependence on Cable Companies
 
  The Company has strategic relationships with seven major cable companies
which are expected to provide through their cable systems the principal
distribution network for the Company's services to its subscribers. The
Company's three principal cable stockholders have granted the Company the
exclusive right to offer high-speed residential consumer Internet services
over their cable systems, subject to certain exceptions. However, the
principal cable stockholders are under no obligation to carry the Company's
services. In addition, the principal cable stockholders' exclusivity
obligations in favor of the Company expire in June 2002, and may be terminated
prior to that date under certain circumstances.
 
  Transmission of data over cable is dependent on the availability of high-
speed two-way hybrid fiber coaxial cable infrastructure. Currently, a
substantial majority of existing cable plants in the United States have not
been upgraded from coaxial cable to hybrid fiber-coaxial cable and, in
addition, are not capable of two-way transmission. Cable system operators have
announced and begun to implement major infrastructure investments in order to
deploy data-over-cable services. However, there can be no assurance that such
infrastructure improvements will be completed.
 
 Dependence on Key Technology Suppliers
 
  The Company currently depends on a limited number of suppliers for certain
key technologies used to build and manage the Company's services. Although the
Company believes that there are alternative suppliers for each of these
technologies, the Company has established favorable relationships with each of
its current suppliers, and it could take a significant period of time to
establish relationships with alternative suppliers and substitute their
technologies. The loss of any of the Company's relationships with its current
suppliers could have a material adverse effect on the Company's financial
condition and results of operations.
 
 Basis of Presentation
 
  The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiary. All significant intercompany transactions and
balances have been eliminated in consolidation.
 
 Use of Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make certain 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 results of operations during the reporting period.
Actual results could differ from those estimates.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 (INFORMATION FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND 1997 IS UNAUDITED)
 
1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
 Interim Financial Information
   
  The interim financial information as of March 31, 1997 and for the three
months ended March 31, 1996 and 1997 is unaudited but includes all
adjustments, consisting only of normal recurring adjustments, that the Company
considers necessary for a fair presentation of its financial position at such
date and its results of operations and cash flows for those periods. Operating
results for the three months ended March 31, 1997 are not necessarily
indicative of results that may be expected for any future periods.     
 
 Revenue Recognition
 
  Monthly customer subscription revenue is recognized in the period in which
subscription services are provided. The Company also earns revenue from cable
system operators for providing certain support services, such as customer
support, local area content development and pre-commercial deployment fees.
Revenue from cable system operators is recognized as the services are
performed. For the period from March 28, 1995 (inception) to December 31, 1995
and the year ended December 31, 1996, such revenue was derived from cable
system operators that are also stockholders of the Company. Revenues also
include the sale of online advertising primarily based on fixed-fee charter
programs.
 
 Property, Equipment and Improvements
 
  Property and equipment are stated at cost. Depreciation and amortization are
computed using the straight-line method over the shorter of the estimated
useful life of the asset or the lease term.
 
  The Company adopted Statement of Financial Accounting Standards No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets
to be Disposed Of," effective January 1, 1996. The adoption did not have a
material impact on the Company's financial statements.
 
 Income Taxes
 
  The Company accounts for income taxes under the liability method. Deferred
tax assets and liabilities are determined based on differences between the
financial reporting and tax bases of assets and are measured using the enacted
tax rates and laws that will be in effect when the differences are expected to
reverse.
 
 Stock-Based Compensation
 
  The Company accounts for stock-based awards to employees in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" ("APB Opinion No. 25") and has adopted the disclosure-only
alternative of Statement of Financial Accounting Standards No. 123,
"Accounting for Stock-Based Compensation" ("FAS 123").
 
 Pro Forma Net Loss Per Share
 
  Except as noted below, pro forma net loss per share is computed using the
weighted average number of common shares outstanding and also gives effect to
the assumed conversion of all outstanding shares of convertible preferred
stock into common stock upon the closing of the Company's initial public
offering (using the as-if-converted method). Common equivalent shares are
excluded from the computation as their effect is antidilutive, except that
pursuant to applicable Securities and Exchange Commission Staff Accounting
Bulletins, common and common equivalent shares (from stock options and
warrants) issued during the period commencing

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
 
 (INFORMATION FOR THE THREE MONTHS ENDED MARCH 31, 1996 AND 1997 IS UNAUDITED)
 
1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
   
 Pro Forma Net Loss Per Share (continued)     
 
twelve months prior to the initial filing date of the proposed public offering
at prices below the assumed public offering price have been included in the
calculation as if they were outstanding for all periods presented (using the
treasury stock method).
 
  Historical net loss per share is not presented since such amounts are not
considered meaningful as a result of the significant change in the Company's
capital structure (Note 5) that will occur in connection with the initial
public offering of its common stock.
 
  In February 1997, the Financial Accounting Standards Board issued Statement
No. 128, "Earnings Per Share" ("FAS 128"), which is required to be adopted on
December 31, 1997. At that time, the Company will be required to change the
method currently used to compute earnings (loss) per share and to restate such
amounts previously reported. Under the new requirements for calculating
primary (basic) earnings (loss) per share, the dilutive effect of stock
options and warrants and convertible preferred stock will be excluded. Fully
diluted earnings per share will include the dilutive effect of common stock
equivalents. The Company has not determined what the impact of FAS 128 will be
on the calculation of primary and fully diluted net loss per share.
 
2. FINANCIAL INSTRUMENTS
 
 Cash and Cash Equivalents
 
  Cash equivalents are highly liquid investments with insignificant interest
rate risk and maturities of three months or less and are stated at amounts
that approximate fair value, based on quoted market prices. Cash equivalents
consist principally of investments in interest-bearing demand deposit accounts
with financial institutions and highly liquid debt securities of corporations
and the U.S. Government. The Company includes in cash and cash equivalents all
short-term, highly liquid investments that mature within three months of their
acquisition date.
 
 Short-Term Cash Investments
 
  The Company has classified all short-term cash investments as available-for-
sale. Available-for-sale securities are carried at amounts that approximate
fair market value based on quoted market prices. Realized gains and losses and
declines in value judged to be other-than-temporary on available-for-sale
securities are included in interest income. Interest on securities classified
as available-for-sale is also included in interest income.
 
  The following is a summary of available-for-sale securities (in thousands):

4. LEASE OBLIGATIONS
   
  The Company leases certain office facilities under non-cancelable operating
leases that expire at various dates through 2009, and which require the
Company to pay operating costs, including property taxes, insurance and
maintenance. These facility leases generally contain renewal options and
provisions adjusting the lease payments based upon changes in the consumer
price index and increases in real estate taxes and operating expenses or in
fixed increments. Rent expense is reflected on a straight-line basis over the
terms of the leases. The Company also has obligations under a number of
capital equipment leases.

5. STOCKHOLDERS' EQUITY (CONTINUED)
 
 Preferred Stock (continued)
 
  Shares of Series AT, AX and AM preferred stock are convertible into Series A
common stock. Shares of Series T preferred stock are convertible into Series B
common stock, and shares of Series K preferred stock are convertible into
Series K common stock, each on a 20-for-1 basis, subject to antidilution
provisions. Conversion is at the option of the holder, or mandatorily as
determined by the appropriate members of the Board of Directors, and automatic
upon the Company's initial public offering of common stock unless the
appropriate number of members of the Board of Directors vote not to require
such automatic conversion.
 
  Holders of the Company's Series AT, AX, AM, K and T preferred stock are
entitled to receive noncumulative dividends in the amount of 10% of the
original issuance price per year in preference to holders of common stock at
the discretion of the Board of Directors. No such dividends have been declared
since the inception of the Company.
 
  In the event of the liquidation of the Company, holders of Series AT, AX,
AM, K and T preferred stock are entitled to receive an amount per share equal
to the original issuance price plus declared and unpaid dividends, prior and
in preference to any distribution of assets to holders of common stock.
   
  The holder of Series T preferred stock has the right, for 60 days after
August 29, 2001 and each anniversary thereof until August 29, 2005, to
purchase all Series K preferred stock at fair market value (the "Call") and,
during the same period and certain other periods, the holders of Series K
preferred stock have the right to require the holder of Series T preferred
stock to purchase all of the Series K preferred stock at fair market value
(the "Put"). The holder of Series T preferred stock has the right to require
an initial public offering of the Company's common stock in lieu of purchasing
Series K preferred stock pursuant to the Put. The Call and the Put expire upon
the Company's initial public offering.     
   
  Upon the exercise of the Call or Put, all other holders of Series AT, AX, AM
and K preferred stock will have the right to participate in the purchase of
the affected securities on a pro rata basis, and such preferred stockholders
will also have the right to exercise a put to the holder of Series T preferred
stock with terms similar to those provided by the Put as described above.     
 
  Holders of preferred stock are entitled to the same number of votes per
share as the common shares into which the preferred shares are convertible. As
of December 31, 1996, one principal cable stockholder controlled approximately
76% of the voting power of the Company as a result of ownership of convertible
preferred stock.

5. STOCKHOLDERS' EQUITY (CONTINUED)
 
 Common Stock (continued)
 
  The holders of Series A, B and K common stock have one, ten and one vote(s)
per share, respectively. Each share of Series B and K common stock is
convertible into one share of Series A common stock at the option of the
holders.
 
 Stock Splits
 
  In August 1996, the Company completed a one-for-ten reverse stock split of
the outstanding shares of Series K and T preferred stock and a two-for-one
stock split of the outstanding shares of Series A common stock. All share and
per share amounts in the accompanying consolidated financial statements have
been retroactively adjusted to reflect the stock splits.
 
 Stock Purchase Agreements
 
  During 1996, the Company entered into stock purchase agreements with certain
employees, officers, directors and consultants under which the Company issued
7,527,000 shares of Series A common stock at prices ranging from $0.01 to
$0.10 per share, and 50,000 shares of Series K preferred stock at $10.00 per
share. Proceeds from the issuance of the restricted stock were received in the
form of cash or five-year secured promissory notes bearing interest at a rate
of approximately 5.9% per annum. Certain of the agreements provide that the
unvested shares are subject to repurchase by the Company upon termination of
employment at the original price paid for the shares. The shares generally
vest at the rate of 25% after one year and ratably on a monthly basis for
three years thereafter. During the year ended December 31, 1996, the Company
repurchased 400,000 shares of common stock pursuant to such agreements.
   
  Under the terms of an employment agreement with an executive officer, so
long as the officer is employed by the Company, and for 90 days thereafter if
his employment is terminated without cause, to the extent the officer sells
any of his vested common shares during a five-year guarantee period beginning
in July 2000 at an average price less than $5 per share, if the Company's
stock is publicly traded, the Company is obligated to pay the officer the
difference between $5 per share and the average price for each share sold. At
December 31, 1996, the officer owned 3,000,000 shares of Series A common stock
and 50,000 shares of Series K common stock (convertible into 1,000,000 shares
of Series K common stock upon completion of an initial public offering of the
Company's common stock). During the year ended December 31, 1996, the Company
accrued compensation expense of $1,675,000 in connection with this agreement,
which amount is included in other long-term liabilities in the consolidated
balance sheet.     
 
 Warrants
 
  In October 1996, the Company issued a warrant to its facilities lessor that
gives the lessor the right to purchase 200,000 shares of Series A common stock
for $15 per share. The warrant is exercisable for a five-year period beginning
in October 1997, or immediately upon an initial public offering of the
Company's common stock. The Company deemed the warrant to have insignificant
fair value at the time of issuance.
 
 Stock Options
 
  In January 1996, the Company adopted the 1996 Incentive Stock Option Plan,
and in July 1996, the Company adopted the 1996 Incentive Stock Option Plan No.
2. The plans provide for incentive stock options, as defined by the Internal
Revenue Code, to be granted to employees, at an exercise price not less than
100% of the fair value at the grant date as determined by the Board of
Directors. The plans also provide for nonqualified

 Stock Options (continued)
 
stock options to be issued to nonemployee officers, directors and consultants
at an exercise price of not less than 85% of the fair value at the grant date.
 
  The options are exercisable immediately upon issuance and generally have a
term of ten years. The Company reserves the right of first refusal to purchase
all shares held by the participant upon termination. Unvested shares may be
repurchased by the Company at the original purchase price. Fully vested shares
may be repurchased by the Company at the higher of the original purchase price
or the fair market value of the shares as determined by the Board of
Directors. The vesting schedule is determined by the Board of Directors at the
time of issuance. Stock options generally vest at the rate of 25% after one
year and ratably on a monthly basis for three years thereafter. The repurchase
right for vested shares expires upon the completion of an initial public
offering of the Company's common stock. The Company has reserved 16,000,000
shares of Series A common stock (less the number of shares purchased by
employees, officers, directors and consultants outside of the plans) for
issuance under the plans.
 
  A summary of activity under the Company's stock option plans is as follows:

5. STOCKHOLDERS' EQUITY (CONTINUED)
   
 Stock Options (continued)     
 
  The Company has recorded deferred compensation expense of $346,000 during
the year ended December 31, 1996 and $4,737,000 during the three months ended
March 31, 1997 for the difference between the exercise or purchase price and
the deemed fair value of certain of the Company's stock options granted and
stock issued under stock purchase agreements. These amounts are being
amortized by charges to operations over the vesting periods of the individual
stock options and stock purchase agreements, which are generally four years. A
portion of the shares issued under certain stock purchase agreements during
the year ended December 31, 1996 vested immediately. As a result the related
compensation charge for the vested shares was recorded in the period in which
the shares were issued.
 
 Pro Forma Disclosures of the Effect of Stock-Based Compensation Plans
 
  Pro forma information regarding results of operations and loss per share is
required by FAS 123 for stock-based awards to employees as if the Company had
accounted for such awards using a valuation method permitted under FAS 123.
 
  From inception through December 31, 1995, the Company made no stock-based
awards to employees. Stock-based awards to employees under stock options and
stock purchase agreements during the year ended December 31, 1996 were valued
using the minimum value method, assuming no expected dividends, a weighted-
average expected life of four years and a weighted-average risk-free interest
rate of 6.5%. Should the Company complete an initial public offering of its
common stock, stock-based awards granted thereafter will be valued using the
Black-Scholes option pricing model. Among other things, the Black-Scholes
model considers the expected volatility of the Company's stock price,
determined in accordance with FAS 123, in arriving at an estimated fair value.
The minimum value method does not consider stock price volatility. Further,
certain other assumptions necessary to apply the Black-Scholes model may
differ significantly from assumptions used to calculate the value of stock-
based awards under the minimum value method.
   
  The weighted-average minimum values of options and nonvested shares issued
to employees during 1996 were each $0.01. For pro forma purposes, the
estimated minimum value of the Company's stock-based awards to employees is
amortized over the vesting period of the underlying instruments. The results
of applying FAS 123 to the Company's stock-based awards to employees for the
period from inception through December 31, 1995 would have no effect on the
Company's results of operations or net loss per share reflected in the
consolidated statement of operations because no such awards were made during
the period. The effect of applying FAS 123 for the year ended December 31,
1996 would not be material to the Company's results of operations or net loss
per share.     
 
 Unaudited Pro Forma Stockholders' Equity
 
  Unaudited pro forma stockholders' equity at March 31, 1997 gives effect to
the conversion into common stock of outstanding shares of preferred stock that
will convert to common stock upon the closing of the Company's initial public
offering of its common stock.

6. INCOME TAXES (CONTINUED)     
 
  Realization of deferred tax assets is dependent on future earnings, if any,
the timing and amount of which are uncertain. Accordingly, a valuation
allowance, in an amount equal to the net deferred tax assets as of December
31, 1995 and 1996, has been established to reflect these uncertainties.
 
  At December 31, 1996, the Company has net operating loss and research and
development tax credit carryforwards for federal and state tax purposes of
approximately $16,002,000 and $120,000, respectively, that will begin to
expire at various dates beginning in years 2003 through 2011, if not utilized.
Certain changes in ownership of the Company, as defined in the Tax Reform Act
of 1996 and similar state provisions, may restrict the utilization of such
carryforwards.
 
7. RELATED PARTY TRANSACTIONS
 
  For the period from March 28, 1995 (inception) to December 31, 1995 and for
the year ended December 31, 1996, the Company purchased services of
approximately $733,000 and $2,726,000 respectively, from certain preferred
stockholders.
 
  The Company entered into an OEM software license agreement under which the
Company paid the vendor $1,388,000 during 1996 and is obligated to pay an
additional $2,331,000 during 1997 as nonrefundable license fees, prepaid
support and services. A member of the Company's Board of Directors is also an
executive officer of the vendor.
   
  Related party transactions with principal cable stockholders are described
in Note 1.     
 
8. RETIREMENT PLAN
 
  The Company has a retirement plan under Section 401(k) of the Internal
Revenue Code. Under the retirement plan, participating employees may defer a
portion of their pretax earnings up to the Internal Revenue Service annual
contribution limit. The Company may make contributions to the plan at the
discretion of the Board of Directors. To date, no such contributions have been
made by the Company.
   
9. SUBSEQUENT EVENTS     
 
 Series C Preferred Stock Financing
 
  In April 1997, the Company issued 240,000 shares of Series C convertible
preferred stock to investors at $200 per share, resulting in cash proceeds of
$48,000,000, less issuance costs. In connection with the issuance, the Company
authorized the designation of 350,000 shares of authorized Series C preferred
shares. Holders of Series C preferred stock are entitled to noncumulative
annual dividends equal to 10% of the issue price if and when declared by the
Board of Directors. Each share of Series C preferred stock is convertible into
20 shares of Series A common stock at the option of the holder, subject to
certain adjustments. Each share of Series C preferred stock will automatically
convert into Series A common stock upon the closing date of an initial public
offering of the Company's common stock. If the offering price per share of the
Series A common stock in an initial public offering is less than the effective
price per share paid for the Series A common stock upon conversion of the
Series C preferred stock, the conversion rate will be adjusted so that the
effective price per share of the Series A common stock issued upon such
conversion will equal the offering price.

 Series C Preferred Stock Financing (continued)     
 
  The Company also issued warrants to purchase 100,000 additional shares of
Series C preferred stock at a price of $200 per share to certain of the Series
C preferred stock investors that are also cable system operators. The warrants
are exercisable from June 2004 or earlier, subject to certain performance
standards being met by the cable systems operators, as specified in the
agreement. The exercise price per share of the warrants will be reduced to the
extent the offering price per share in an initial public offering of the
Company's common stock is less than the exercise price of the warrants on as-
if-converted basis.
 
 Proposed Public Offering of Common Stock
   
  In May 1997, the Board of Directors authorized management of the Company to
file a Registration Statement with the Securities and Exchange Commission
permitting the Company to sell shares of its Series A common stock to the
public. In addition, the Company's Board of Directors authorized an increase
in the number of authorized shares of Series A common stock from 150,000,000
to 200,000,000 and a decrease in the number of authorized shares of preferred
stock from 14,522,613 to 9,650,000 upon completion of its initial public
offering, subject to stockholder approval. In addition, the Board of Directors
approved the conversion of all outstanding preferred stock into common stock
upon the closing of the initial public offering.     
 
 1997 Equity Incentive Plan
   
  The Company's 1997 Equity Incentive Plan was adopted by the Board of
Directors in May 1997 to be effective upon the completion of the Company's
initial public offering of its Series A common stock, subject to stockholder
approval. The 1997 Plan provides for the grant of incentive stock options,
nonqualified stock options, restricted stock awards and stock bonuses to
employees, directors and consultants of the Company. The total number of
shares of Series A common stock reserved for issuance under the 1997 Plan is
16,000,000 less the total number of shares issued or issuable to employees,
officers, directors and consultants under restricted stock purchase agreements
and the 1996 Incentive Stock Option Plans (Note 5) and shares issued under the
1997 Employee Stock Purchase Plan.     
 
 1997 Employee Stock Purchase Plan
   
  The Company's 1997 Employee Stock Purchase Plan was adopted by the Board of
Directors in May 1997 to be effective upon the completion of the Company's
initial public offering of its common stock, subject to stockholder approval.
The Company has reserved a total of 400,000 shares of Series A common stock
for issuance under the plan. Eligible employees may purchase common stock at
85% of the lesser of the fair market value of the Company's common stock on
the first day of the applicable offering period or the last day of the
applicable purchase period.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
   
  As permitted by the Delaware General Corporation Law, the Registrant's
Certificate of Incorporation includes a provision that eliminates the personal
liability of its directors to the Registrant or its stockholders for monetary
damages for breach of fiduciary duty as a director, except for liability (i)
for any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or that involve
intentional misconduct or a knowing violation of law; (iii) under Section 174
of the Delaware General Corporation Law or (iv) for any transaction from which
the director derived an improper personal benefit. As permitted by Section 145
of the Delaware General Corporation Law, Registrant's Certificate of
Incorporation further provides (i) for mandatory indemnification, to the
fullest extent permitted by applicable law, for any person who is or was a
director or officer of the Company, or a person who is a legal representative
of such director or officer, or is or was serving at the request of the
Company as a director, officer, employee or agent of another corporation or of
a partnership, joint venture, trust, enterprise or nonprofit entity, including
service with respect to employee benefit plans, against all liability and loss
suffered and expenses (including attorneys' fees) reasonably incurred by such
person, (ii) that the indemnity of any person who was or is serving at the
Company's request as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust, enterprise or nonprofit entity
must be reduced by any amount such person may collect as indemnification from
such other corporation, partnership, joint venture, trust, enterprise or
nonprofit entity, (iii) that the Registrant must advance to its directors and
officers the expenses (including attorneys' fees) incurred in defending any
proceeding provided such directors and officers provide Registrant an
undertaking to repay such advances if indemnification is determined to be
unavailable, (iv) that the rights conferred in the Certificate of
Incorporation are not exclusive and (v) that Registrant may not retroactively
amend the Certification of Incorporation provisions relating to indemnity.
Registrant has also entered into Indemnification Agreements with each of its
directors and executive officers. Reference is also made to Article VIII of
the Underwriting Agreement, which provides for the indemnification of
officers, directors and controlling persons of the Registrant against certain
liabilities.     
   
  The indemnification provision in the Company's Certificate of Incorporation
and the Indemnification Agreements entered into between the Registrant and
each of its directors and executive officers may be sufficiently broad to
permit indemnification of the Registrant's directors and officers for
liabilities arising under the Securities Act.     
 
  The Registrant, with approval by the Registrant's Board of Directors, has
applied for, and expects to obtain, directors' and officers' liability
insurance with a per claim and annual aggregate coverage limit of $   .

(1) Upon the closing of the Company's initial public offering, each share of
    Preferred Stock will convert automatically into 20 shares of the
    appropriate series of Common Stock subject to adjustment of the Series C
    Preferred Stock conversion rate if the offering price is less than $10.00
    per share.
(2) These shares were subsequently exchanged for a like number of shares of
    Series AT Preferred Stock.
(3) The Registrant issued these shares in exchange for an Internet domain
    name.
(4) Of these shares, 701,850 have been repurchased by the Registrant.
(5) Each individual paid a portion or all of the purchase price in cash
    (aggregating $272,010). Four officers and six other employees paid most of
    their respective purchase prices with promissory notes (aggregating
    $128,790).
(6) Of these shares, 263,574 have been repurchased by the Registrant.
(7) Each individual paid a portion or all of the purchase price in cash
    (aggregating $541,313). Two executive officers and four other employees
    paid most of their respective purchase prices with promissory notes
    (aggregating $239,400).
 
  All sales of Series A Common Stock made pursuant to the exercise of stock
options granted under the Registrant's stock option plans or pursuant to
restricted stock purchase agreements were made pursuant to the exemption from
the registration requirements of the Securities Act afforded by Rule 701
promulgated under the Securities Act.
   
  The sales to two foreign companies (Rogers Cablesystems Limited and Shaw
Cablesystems Ltd. in Canada) of Series C Preferred Stock and warrants to
purchase Series C Preferred Stock were made in reliance on Regulation S and
Section 4(2) of the Securities Act. The sales to each company were offshore
transactions, and no directed selling efforts were made in the United States
by the Registrant, a distributor, any of their respective affiliates or any
person acting on behalf of any of the foregoing. Each company represented that
(a) it was not a "U.S. person" within the meaning of Regulation S, (b) it did
not acquire the securities for the account of or     
 
                                     II-2

benefit of any U.S. person, (c) the offer to purchase the securities was not
made to it in the United States, (d) to the best of its knowledge, the offer
and sale of the securities was made in an "offshore transaction" complying
with the provisions of Rule 903 of Regulation S under the Securities Act, (e)
it acquired the securities for investment and not with a view to the sale or
other distribution thereof within the meaning of the Securities Act and (f) it
will resell or transfer the securities only in accordance with the provisions
of Regulation S, pursuant to registration under the Securities Act or pursuant
to another available exemption from registration. Each company agreed that
until two years after the closing for the purchase of the securities or such
earlier time as may be permitted under Regulation S, it would not offer or
sell any of the securities in the United States or to any U.S. person unless
the securities are registered under the Securities Act or an exemption from
the registration requirements under the Securities Act is available. The
securities contain a legend to the effect that transfer is prohibited except
in accordance with the provisions of Regulation S. Each company acknowledged
that the Registrant is required to refuse, and will refuse, to register any
transfer of the Securities not made in accordance with the provisions of
Regulation S.     
 
  All other sales were made in reliance on Section 4(2) of the Securities Act
and/or Regulation D promulgated under the Securities Act. These sales were
made without general solicitation or advertising. Each purchaser was a
sophisticated investor with access to all relevant information necessary to
evaluate the investment who represented to the Registrant that the shares were
being acquired for investment.

ITEM 17. UNDERTAKINGS.
 
  The undersigned Registrant hereby undertakes to provide to the Underwriter
at the closing specified in the Underwriting Agreement certificates in such
denominations and registered in such names as required by the Underwriter to
permit prompt delivery to each purchaser.
 
  Insofar as indemnification for liabilities arising under the Securities Act
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the provisions described under Item 14 above, or
otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
the event that a claim for indemnification against such liabilities (other
than the payment by the Registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of
any action, suit or proceeding) is asserted by such director, officer or
controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.
 
  The undersigned Registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act,
  the information omitted from the form of prospectus filed as part of this
  Registration Statement in reliance upon Rule 430A and contained in a form
  of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or
  497(h) under the Securities Act 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.

Stock by surrendering such holder's certificate or certificates for the series
of Convertible Common Stock to be converted, duly endorsed, at the office of the
Corporation or any transfer agent for the Convertible Common Stock, together
with a written notice to the Corporation at such office that such holder elects
to convert all or a specified number of shares of such series of Convertible
Common Stock represented by such certificate and stating the name or names in
which such holder desires the certificate or certificates for Series A Common
Stock to be issued. If so required by the Corporation, any certificate for
shares surrendered for conversion shall be accompanied by instruments of
transfer, in form satisfactory to the Corporation, duly executed by the holder
of such shares or the duly authorized representative of such holder. Promptly
thereafter, the Corporation shall issue and deliver to such holder or such
holder's nominee or nominees, a certificate or certificates for the number of
shares of Series A Common Stock to which such holder shall be entitled as herein
provided (provided that the Corporation will use commercially reasonable efforts
to make such delivery within two Business Days after receipt of the certificate
or certificates, notice, and if required, instruments of transfer referred to
above). Such conversion shall be deemed to have been made at the close of
business on the date of receipt by the Corporation or any such transfer agent of
the certificate or certificates, notice and, if required, instruments of
transfer referred to above, and the Person or Persons entitled to receive the
Series A Common Stock issuable on such conversion shall be treated for all
purposes as the record holder or holders of such Series A Common Stock on that
date; provided, however, that the conversion may, at the option of any holder
      -----------------
surrendering Convertible Common Stock for conversion, be conditioned upon the
IPO or upon notice by such holder to the Corporation of the occurrence of any
other specified event. A number of shares of Series A Common Stock equal to the
number of shares of Series B Common Stock and Series K Common Stock,
respectively, outstanding from time to time shall be set aside and reserved for
issuance upon conversion of shares of Series B Common Stock and of Series K
Common Stock, respectively. Shares of Series B Common Stock and Series K Common
Stock that have been converted hereunder shall be retired and shall not be
reissued. Shares of Series A Common Stock shall not be convertible into shares
of Series B Common Stock or Series K Common Stock.

     3.   Dividends.  Subject to paragraph 4 of this Section B, whenever a
          ---------
dividend is paid to the holders of one series of Common Stock, the Corporation
also shall pay to the holders of all other series of Common Stock a dividend per
share equal to the dividend per share paid to the holders of such first series
of Common Stock. Dividends shall be payable only if, as and when declared by the
Board of Directors out of the assets of the Corporation legally available

          (a)  Dividend Rights; Dividend Payment Dates. Subject to the prior
               ---------------------------------------
preferences and other rights of any Senior Stock and the provisions of this
Article IV, the holders of Convertible Preferred Stock shall be entitled to
receive, when, as and if declared by the Board of Directors, in its discretion,
but prior and in preference to any declaration or payment of dividends on any
Junior Stock, out of unrestricted funds legally available therefor, quarterly
cash dividends per share at the rate of 10.0% per annum of the Issue Price (the
"CONVERTIBLE PREFERRED DIVIDEND"). The Convertible Preferred Dividend shall be
noncumulative; that is, the Convertible Preferred Dividend shall be paid only
when, as and if declared by the Board of Directors, it being intended that a
Convertible Preferred Dividend not declared in any quarter will not be carried
over to a future quarter.

          (b)  Dividends on Junior Stock.  In addition, following the payment of
               -------------------------
the Convertible Preferred Dividend for any period, in the event that the Board
of Directors proposes, subject to the provisions of this paragraph, to declare
or pay a dividend on any Junior Stock in cash or consisting of assets, property
or securities other than Common Stock, then the holders of Convertible Preferred
Stock shall be entitled to receive, when and as declared by the Board of
Directors, an additional dividend amount (the "PARTICIPATING DIVIDEND")
determined as follows: (i) in the event that a dividend is declared with respect
to Junior Stock (other than Common Stock (or any other security that is
convertible into, or exercisable or exchangeable for Common Stock)), the
Participating Dividend payable to the holders of the Convertible Preferred Stock
shall equal an amount per share equal to the dividend to be paid on each share
or other unit of Junior Stock multiplied by a fraction, the numerator of which
is the Liquidation Price of a share of Convertible Preferred Stock and the
denominator of which is the lowest of (x) the liquidation price (if applicable),
(y) the redemption price (if applicable) and (z) the price at which such share
or unit was originally purchased (as adjusted for stock splits, stock dividends
and the like occurring after the Filing Date), of a share or other unit of such
Junior Stock; or (ii) in the event that a dividend is declared with respect to
Junior Stock which is Common Stock or such Junior Stock is convertible into, or
exercisable or exchangeable for, Common Stock, then the amount of the
Participating Dividend per share of Convertible Preferred Stock shall be (x) (1)
the amount of the dividend to be paid on a single share of Common Stock, or (2)
if such Junior Stock is convertible into, or exercisable or exchangeable for,
Common Stock, such amount as would be payable on each share of Common Stock into
which such Junior Stock is convertible into or exercisable or exchangeable for,
multiplied by (y) the number of shares of Common Stock into which a share of
Convertible Preferred Stock may then be converted. Dividends payable on the
Convertible Preferred Stock shall be calculated on the basis of a 360-day year
of twelve 30-day months. Dividends on the Convertible Preferred Stock will be
payable, as provided in paragraph 2(e) below, to the holders of record of the
Convertible Preferred Stock as of the close of business on the Record Date for
such dividend payment.

<PAGE>
 
           (c)  Dividends on Parity Stock. So long as any shares of Convertible
                -------------------------
Preferred Stock are outstanding and dividends on such shares of Convertible
Preferred Stock have not been (or are not contemporaneously) declared and paid
in full for the two immediately preceding Dividend Periods, no dividends shall
be declared or paid or set apart for payment by the Corporation upon any Parity
Stock; provided, however, that a dividend may be declared and paid (regardless
       --------  -------
of whether such dividends have been paid for any preceding Dividend Period) pro
rata with respect to all Convertible Preferred Stock and Parity Stock then
outstanding such that the amounts of any dividends declared per share on the
Convertible Preferred Stock and such Parity Stock shall in all cases bear to
each other the same ratio that the Convertible Preferred Dividend (assuming such
dividend had been declared by the Board) and, if applicable, any Participating
Dividend (collectively, the "CONVERTIBLE FULL DIVIDEND") per share of
Convertible Preferred Stock for the then-current Dividend Period and dividends
on shares of such other Parity Stock for the then-current Dividend Period
(excluding any accumulated or accrued dividends on such Parity Stock) bear to
each other.

          (d)  Other Limitations on Dividends and Repurchases. If the
               ----------------------------------------------
Convertible Full Dividend has not been declared and paid or set apart for
payment for the Dividend Payment Date falling in the then-current Dividend
Period, then, with respect to such then-current Dividend Period, (i) the
Corporation shall not declare or pay any dividend on, or make any distribution
with respect to, any Junior Stock or set aside any money or assets for such
purpose and (ii) the Corporation shall not repurchase, redeem or otherwise
acquire for value any shares of its Junior Stock, any equity securities of any
Subsidiary of the Corporation or any options, warrants or other rights to
acquire such securities; provided, however, that the Corporation may at any
                         --------  -------
time, out of funds legally available therefor, repurchase (x) from employees,
directors or consultants of the Corporation or any Subsidiary thereof, shares of
equity securities of the Corporation, equity securities of any Subsidiary of the
Corporation or options, warrants or other rights to acquire such securities
issued to such employees, directors or consultants provided that such repurchase
is pursuant to repurchase or redemption rights contained in the instrument
pursuant to which such securities were originally issued and (y) from the
Comcast Stockholder Group any Subject Shares upon the Corporation's exercise of
the @Home Repurchase Right pursuant to the Master Distribution Agreement (the
right or obligation of the Corporation to so repurchase or redeem such
securities pursuant to the foregoing clauses (x) and (y), is hereinafter
referred to as a "PERMITTED REPURCHASE").

          (e)  Special Record Date. Dividends may be declared and paid at any
               -------------------
time (subject to the rights of any Senior Stock and, if applicable, to the
concurrent satisfaction of any dividend arrearages then existing with regard to
any Parity Stock which ranks on a parity basis with the Convertible Preferred
Stock as to the payment of dividends) without reference to the regular Dividend
Payment Date, to holders of record as of the close of business on such date, not
more than 45 days nor less than 10 days preceding the payment date thereof, as
may be fixed by the Board of Directors (the "SPECIAL RECORD DATE"). Notice of
each Special Record Date shall be given, not more than 45 days nor less than 10
days prior thereto, to the holders of record of the shares of Convertible
Preferred Stock.

          (f)  Pro Rata Payment. All dividends paid with respect to the shares
               ----------------
of Convertible Preferred Stock pursuant to this paragraph 2 shall be paid pro
rata to all the holders 

                                       16
<PAGE>
 
of shares of Convertible Preferred Stock outstanding on the applicable Record
Date or Special Record Date, as the case may be.

          (g)  Termination of Convertible Preferred Dividend Right. In the event
               ---------------------------------------------------
that the Special Directors and the Special K Director determine by a
Supermajority Vote not to require the Mandatory Conversion upon the IPO, then
upon the IPO, unless the Special Directors and the Special K Director have also
determined by a Supermajority Vote not to terminate the Convertible Preferred
Dividend right, the provisions of paragraph 2(a), (b), (c) and (d) shall
terminate and the holders of Convertible Preferred Stock shall be entitled to
receive dividends if, as and when the Board shall declare dividends on the
Common Stock other than dividends payable in Common Stock pursuant to which such
Convertible Preferred Stock is entitled to an adjustment pursuant to paragraph
6(c) below. The amount of such dividend per share of Convertible Preferred Stock
shall be the amount of the dividend to be paid on a single share of Common Stock
multiplied by the number of shares of Common Stock into which a share of
Convertible Preferred Stock may then be converted.

     3.   Distributions Upon Liquidation, Dissolution or Winding Up.
          ---------------------------------------------------------

          (a)  Liquidation Preference Prior to IPO. Prior to the IPO and subject
               -----------------------------------
to the prior payment in full of the preferential amounts to which any Senior
Stock is entitled, in the event of any liquidation, dissolution or winding up of
the Corporation, whether voluntary or involuntary, the holders of Convertible
Preferred Stock shall be entitled to receive from the assets of the Corporation
available for distribution to stockholders, before any payment or distribution
shall be made to the holders of any Junior Stock, an amount in cash (and, to the
extent sufficient cash is not available for such payment, property at its fair
market value) per share, equal to the Liquidation Price of such share of
Convertible Preferred Stock as of the date of payment or distribution, which
payment or distribution shall be made pari passu with any such payment or
                                      ---- -----
distribution made to the holders of any Parity Stock ranking on a parity basis
with the Convertible Preferred Stock with respect to distributions upon
liquidation, dissolution or winding up of the Corporation. Except as provided in
paragraph 3(b) below, the holders of Convertible Preferred Stock shall be
entitled to no other or further distribution of or participation in any
remaining assets of the Corporation after receiving the Liquidation Price per
share. If, upon distribution of the Corporation's assets in liquidation,
dissolution or winding up, the assets of the Corporation to be distributed among
the holders of the Convertible Preferred Stock and to all holders of any Parity
Stock ranking on a parity basis with the Convertible Preferred Stock with
respect to distributions upon liquidation, dissolution or winding up shall be
insufficient to permit payment in full to such holders of the respective
preferential amounts to which they are entitled, then the entire assets of the
Corporation to be distributed to holders of the Convertible Preferred Stock and
such Parity Stock shall be distributed pro rata to such holders based upon the
aggregate of the full preferential amounts to which the shares of Convertible
Preferred Stock and such Parity Stock would otherwise respectively be entitled.
In the event of (i) a consolidation or merger of the Corporation with or into
any other corporation or other entity in which the holders of all of the
Corporation's outstanding shares of capital stock immediately before the
effectiveness of such transaction do not, immediately after the effectiveness of
such transaction, own capital stock representing a majority of the voting power
of the surviving corporation or other entity of such transaction (or the
immediate parent of such surviving corporation or other entity), or (ii) a sale
of all or substantially all of the assets of the Corporation other than in

                                       17
<PAGE>
 
connection with a Related Business Transaction (as defined below), the holders
of a majority of the outstanding shares of each series of the Corporation's
Preferred Stock, voting separately as a series (or consenting in writing), shall
be entitled to deem, solely as to the series of Preferred Stock which has so
voted or consented, such merger, consolidation or sale of assets to be a
liquidation, dissolution or winding up of the Corporation within the meaning of
this paragraph 3, provided, that written notice of such vote or such written
consents must be received by the Corporation at least five (5) days prior to the
effectiveness of such transaction; and provided further, that the Corporation
shall have provided holders of Convertible Preferred Stock with the notice
required to be delivered to them pursuant to paragraph 6(g) of Section C of this
Article IV of such deemed liquidation, dissolution or winding up of the
Corporation. For purposes of this Certificate, a "RELATED BUSINESS TRANSACTION"
shall mean any sale or other disposition of all or substantially all of the
properties and assets of the Corporation in which (i) the Corporation receives
as proceeds of such disposition primarily equity securities (including, without
limitation, capital stock, convertible securities, partnership or limited
partnership interests and other types of equity securities, without regard to
the voting power or contractual or other management or governance rights related
to such equity securities) of the purchaser or acquiror of such properties and
assets of the Corporation, including but not limited to any entity which
succeeds (by merger, formation of a joint venture enterprise or otherwise) to
such properties and assets of the Corporation (or the immediate parent of such
purchaser or acquiror), and (ii) the securities received by the Corporation,
immediately after the effectiveness of such transaction, have a majority of the
voting power of the purchaser or acquiror of such properties and assets of the
Corporation, including but not limited to any entity which succeeds (by merger,
formation of a joint venture enterprise or otherwise) to such properties and
assets of the Corporation (or the immediate parent of such purchaser or
acquiror). Notice of the liquidation, dissolution or winding up of the
Corporation shall be given, not less than 20 days prior to the date on which
such liquidation, dissolution or winding up or merger or sale of assets is
expected to take place or become effective, to the holders of record of the
shares of Convertible Preferred Stock, during which 20 day period such holders
shall continue to be entitled to exercise their conversion rights as set forth
in paragraph 6 of this Section C.

          (b)  Liquidation Preference After IPO. In the event that the Special
               --------------------------------
Directors and the Special K Director determine by a Supermajority Vote not to
require the Mandatory Conversion upon the IPO, then upon the IPO, unless the
Special Directors and the Special K Director have also determined by a
Supermajority Vote not to change the Liquidation Price of the Convertible
Preferred Stock as described in paragraph 1 of this Section C, subject to prior
payment in full of the Liquidation Price (as changed as described in paragraph 1
of this Section C) on each outstanding share of Convertible Preferred Stock and
if there are any assets of the Corporation available for distribution to
stockholders, such remaining assets shall be distributed among the holders of
the then outstanding Common Stock and Convertible Preferred Stock pro rata
according to the number of shares of Common Stock held by each holder thereof
(where, for this purpose, holders of shares of Convertible Preferred Stock will
be deemed to hold the greatest whole number of shares of Common Stock then
issuable upon conversion in full of such shares of Convertible Preferred Stock).

     4.  Limitations on Dividends and Redemptions.  So long as any shares of
         ----------------------------------------
Convertible Preferred Stock are outstanding, the Corporation shall not, absent
the requisite Board Action and the approval of the holders of the Convertible
Preferred Stock, as required pursuant to 

                                       18
<PAGE>
 
paragraph 7(c) of this Section C, (a) declare or pay any dividend, or make any
distribution, on, or (b) repurchase, redeem or otherwise acquire for value any
shares of, any Junior Stock, any equity securities of any Subsidiary of the
Corporation or any options, warrants or other rights to acquire such securities
other than (i) the payment of dividends on any Junior Stock solely in shares of
Junior Stock or the redemption, purchase or other acquisition of Junior Stock
solely in exchange for (together with a cash adjustment for fractional shares,
if any) shares of Junior Stock; or (ii) a repurchase or redemption of equity
securities of the Corporation, any equity securities of any Subsidiary of the
Corporation, or any options, warrants or other rights to acquire any such
securities which is a Permitted Repurchase.

     5.   Status of Reacquired Convertible Preferred Stock.  In the event that
          ------------------------------------------------
the Corporation repurchases or otherwise reacquires shares of Convertible
Preferred Stock, such shares shall be retired and shall not be reissued.

     6.   Conversion.
          -----------

          (a)  Optional and Mandatory Conversion.  Each outstanding share of
               ---------------------------------
Series AM Preferred Stock shall be convertible at the option of the holder at
any time into fully paid and non-assessable full shares of Series A Common Stock
at the then effective Conversion Rate (as defined below) for such shares. Each
outstanding share of Series AT Preferred Stock shall be convertible at the
option of the holder at any time into fully paid and non-assessable full shares
of Series A Common Stock at the then effective Conversion Rate for such shares.
Each outstanding share of Series AX Preferred Stock shall be convertible at the
option of the holder at any time into fully paid and non-assessable full shares
of Series A Common Stock at the then effective Conversion Rate for such shares.
Each outstanding share of Series K Preferred Stock shall be convertible at the
option of the holder at any time into fully paid and non-assessable full shares
of Series K Common Stock at the then effective Conversion Rate for such shares.
Each outstanding share of Series T Preferred Stock shall be convertible at the
option of the holder at any time into fully paid and non-assessable full shares
of Series B Common Stock at the then effective Conversion Rate for such shares.
In addition, unless the Special Directors and the Special K Director determine
by a Supermajority Vote not to require conversion of all outstanding shares of
Convertible Preferred Stock upon the IPO, then, subject to the receipt of any
required regulatory consents or approvals or the filing of any required notices
with any governmental entities and the expiration of any waiting period related
thereto, the holders of all shares of Convertible Preferred Stock shall be
deemed to have converted such shares into shares of Series A Common Stock,
Series B Common Stock or Series K Common Stock (whichever series of Common Stock
such shares of Convertible Preferred Stock are initially convertible into)
immediately prior to the IPO (or at such earlier or later time as is determined
by a Unanimous Vote) (such conversion upon the IPO or such earlier or later time
is referred to herein as the "MANDATORY CONVERSION"). All such conversions of
Convertible Preferred Stock shall be effected in such manner and upon such terms
and conditions as hereinafter provided in this paragraph 6. In case cash,
securities or property other than Series A Common Stock, Series B Common Stock
or Series K Common Stock, as applicable, shall be payable, deliverable or
issuable upon conversion as provided herein, then all references to Series A
Common Stock, Series B Common Stock or Series K Common Stock in this paragraph 6
shall be deemed to apply, so far as appropriate and as nearly as may be, to such
cash, property or other securities. Notwithstanding anything to the contrary in
this Article IV, subject to the provisions for 

                                       19
<PAGE>
 
adjustment hereinafter set forth in this paragraph 6, any provisions in this
Article that refer to a conversion of the Convertible Preferred Stock shall
mean, (i) in the case of the Series T Preferred Stock, the conversion of the
Series T Preferred Stock into the Series B Common Stock, (ii) in the case of the
Series K Preferred Stock, the conversion of the Series K Preferred Stock into
the Series K Common Stock, and (iii) in the case of the Series A Preferred
Stock, the conversion of the Series A Preferred Stock into the Series A Common
Stock.

          (b)  Initial Conversion Rates. Subject to the provisions for
               ------------------------
adjustment hereinafter set forth in this paragraph 6, (i) each series of the
Series A Preferred Stock may be converted into Series A Common Stock at the
initial conversion rate of twenty fully paid and non-assessable shares of Series
A Common Stock for each share of Series A Preferred Stock so converted; (ii) the
Series K Preferred Stock may be converted into Series K Common Stock at the
initial conversion rate of twenty fully paid and non-assessable shares of Series
K Common Stock for each share of Series K Preferred Stock so converted; and
(iii) the Series T Preferred Stock may be converted into Series B Common Stock
at the initial conversion rate of twenty fully paid and non-assessable shares of
Series B Common Stock for each share of Series T Preferred Stock so converted.
(This conversion rate as from time to time adjusted cumulatively pursuant to the
provisions of this paragraph is hereinafter referred to as the "CONVERSION
RATE").

          (c)  Adjustments for Stock Splits, Stock Dividends, Etc. In case after
               ---------------------------------------------------  
the Filing Date the Corporation shall (i) pay a dividend or make a distribution
on its outstanding shares of Series A Common Stock, Series B Common Stock or
Series K Common Stock in shares of its Common Stock, (ii) subdivide the then
outstanding shares of Series A Common Stock, Series B Common Stock or Series K
Common Stock into a greater number of shares of Series A Common Stock, Series B
Common Stock or Series K Common Stock, (iii) combine the then outstanding shares
of Series A Common Stock, Series B Common Stock or Series K Common Stock into a
smaller number of shares of Series A Common Stock, Series B Common Stock or
Series K Common Stock, or (iv) issue by reclassification of its shares of Series
A Common Stock, Series B Common Stock or Series K Common Stock any shares of any
other class of capital stock of the Corporation (including any such
reclassification in connection with a merger in which the Corporation is the
continuing corporation), then the Conversion Rate in effect immediately prior to
the opening of business on the record date for such dividend or distribution or
the effective date of such subdivision, combination or reclassification shall be
adjusted so that the holder of each share of the Convertible Preferred Stock
thereafter surrendered for conversion shall be entitled to receive the number
and kind of shares of capital stock of the Corporation that such holder would
have owned or been entitled to receive immediately following such action had
such shares of Convertible Preferred Stock been converted immediately prior to
such time into the series of Common Stock into which such series of Convertible
Preferred Stock is initially convertible. An adjustment made pursuant to this
paragraph 6(c) for a dividend or distribution shall become effective immediately
after the record date for the dividend or distribution and an adjustment made
pursuant to this paragraph 6(c) for a subdivision, combination or
reclassification shall become effective immediately after the effective date of
the subdivision, combination or reclassification. Such adjustment shall be made
successively whenever any action listed above shall be taken. For purposes of
this paragraph 6(c), in the event the Corporation takes any of the actions
described in clauses (i) through (iv) above with respect to the Series A Common
Stock at a time when no shares of Series B Common Stock or Series K Common Stock
are issued and are outstanding such that a corresponding 

                                       20
<PAGE>
 
dividend, subdivision, combination or reclassification with respect to the
Series B Common Stock or Series K Common Stock is not required in accordance
with paragraph 4 of Section B of this Certificate, then the Conversion Rate of
the Convertible Preferred Stock shall be adjusted in accordance with the
foregoing provisions of this paragraph 6(c) as if shares of Series B Common
Stock and/or Series K Common Stock were outstanding on the record date for such
dividend or distribution or the effective date for such subdivision, combination
or reclassification and the Corporation otherwise satisfied its obligations
under paragraph 4 of Section B of this Certificate.

          (d)  Adjustments for Reclassification, Merger, Etc.  In case of any
               ---------------------------------------------
reclassification or change in the Series A Common Stock, Series B Common Stock
or Series K Common Stock (other than any reclassification or change referred to
in paragraph 6(c) and other than a change in par value) or in case of any
consolidation of the Corporation with any other corporation or any merger of the
Corporation into another corporation or of another corporation into the
Corporation (other than a merger in which the Corporation is the continuing
corporation and which does not result in any reclassification or change (other
than a change in par value or any reclassification or change to which paragraph
6(c) is applicable) in the outstanding Series A Common Stock, Series B Common
Stock or Series K Common Stock), or in case of any sale or transfer to another
corporation or entity (other than by mortgage or pledge) of all or substantially
all of the properties and assets of the Corporation, in any such case after the
Filing Date, the Corporation (or its successor in such consolidation or merger)
or the purchaser of such properties and assets shall make appropriate provision
so that the holder of a share of the Convertible Preferred Stock shall have the
right thereafter to convert such share into the kind and amount of shares of
stock and other securities and property that such holder would have owned
immediately after such reclassification, change, consolidation, merger, sale or
transfer if such holder had converted such share into Series A Common Stock,
Series B Common Stock or Series K Common Stock, as applicable, immediately prior
to the effective date of such reclassification, change, consolidation, merger,
sale or transfer (assuming for this purpose (to the extent applicable) that such
holder failed to exercise any rights of election and received per share of
Series A Common Stock, Series B Common Stock or Series K Common Stock, as
applicable, the kind and amount of shares of stock and other securities and
property received per share by a plurality of the non-electing shares), and the
holders of the Convertible Preferred Stock shall have no other conversion rights
under these provisions; provided, that effective provision shall be made, in the
Articles or Certificate of Incorporation of the resulting or surviving
corporation or otherwise or in any contracts of sale or transfer, so that the
provisions set forth herein for the protection of the conversion rights of the
Convertible Preferred Stock shall thereafter be made applicable, as nearly as
reasonably may be to any such other shares of stock and other securities and
property deliverable upon conversion of the Convertible Preferred Stock
remaining outstanding or other convertible preferred stock or other Convertible
Securities received by the holders of Convertible Preferred Stock in place
thereof; and provided, further, that any such resulting or surviving corporation
or purchaser shall expressly assume the obligation to deliver, upon the exercise
of the conversion privilege, such shares, securities or property as the holders
of the Convertible Preferred Stock remaining outstanding, or other convertible
preferred stock or other convertible securities received by the holders in place
thereof, shall be entitled to receive pursuant to the provisions hereof, and to
make provisions for the protection of the conversion rights as above provided.

<PAGE>
 
          (e)  Notice of Adjustments in Conversion Rates. Whenever the
               -----------------------------------------
Conversion Rate or the conversion privilege shall be adjusted as provided in
paragraphs 6(c) or (d), the Corporation shall promptly cause a notice to be
mailed to the holders of record of the Convertible Preferred Stock describing
the nature of the event requiring such adjustment, the Conversion Rate in effect
immediately thereafter and the kind and amount of stock or other securities or
property into which the Convertible Preferred Stock shall be convertible after
such event. Where appropriate, such notice may be given in advance and included
as a part of a notice required to be mailed under the provisions of paragraph
6(g).

          (f)  Calculation and Timing of Adjustments. The Corporation may, but
               -------------------------------------
shall not be required to, make any adjustment of the Conversion Rate if such
adjustment would require an increase or decrease of less than 1% in such
Conversion Rate; provided, however, that any adjustments which by reason of this
paragraph 6(f) are not required to be made shall be carried forward and taken
into account in any subsequent adjustment. All calculations under this paragraph
6 shall be made to the nearest 1/100th of a share. In any case in which this
paragraph 6(f) shall require that an adjustment shall become effective
immediately after a record date for such event, the Corporation may defer until
the occurrence of such event (x) issuing to the holder of any shares of
Convertible Preferred Stock converted after such record date and before the
occurrence of such event the additional shares of Series A Common Stock, Series
B Common Stock or Series K Common Stock or other capital stock issuable upon
such conversion by reason of the adjustment required by such event over and
above the shares of Series A Common Stock, Series B Common Stock or Series K
Common Stock or other capital stock issuable upon such conversion before giving
effect to such adjustment and (y) paying to such holder cash in lieu of any
fractional interest to which such holder is entitled pursuant to paragraph 6(l);
provided, however, that, if requested by such holder, the Corporation shall
deliver to such holder a due bill or other appropriate instrument evidencing
such holder's right to receive such additional shares of Series A Common Stock,
Series B Common Stock or Series K Common Stock or other capital stock, and such
cash, upon the occurrence of the event requiring such adjustment.

          (g)  Notice of Certain Events.  In case at any time:
               ------------------------

               (i)   the Corporation shall take any action which would require
          an adjustment in the Conversion Rate pursuant to this paragraph 6;

               (ii)  there shall be any capital reorganization or
          reclassification of the Common Stock (other than a change in par
          value), or any consolidation or merger to which the Corporation is a
          party and for which approval of any stockholders of the Corporation is
          required, or any sale, transfer or lease of all or substantially all
          of the properties and assets of the Corporation, or a tender offer for
          shares of Common Stock representing at least a majority of the total
          voting power represented by the outstanding shares of Common Stock
          which has been recommended by the Board of Directors as being in the
          best interests of the holders of Common Stock; or

                                       22
<PAGE>
 
               (iii) there shall be a voluntary or involuntary dissolution,
          liquidation or winding up of the Corporation;

then, in any such event, the Corporation shall give written notice to the
holders of the Convertible Preferred Stock at their respective addresses as the
same appear on the books of the Corporation, at least twenty days (or ten days
in the case of a recommended tender offer as specified in clause (ii) above)
prior to any record date for such action, dividend or distribution or the date
as of which it is expected that holders of Common Stock of record shall be
entitled to exchange their shares of Common Stock for securities or other
property, if any, deliverable upon such reorganization, reclassification,
consolidation, merger, sale, transfer, lease, tender offer, dissolution,
liquidation or winding up, during which period such holders may exercise their
conversion rights; provided, however, that any notice required by any event
described in clause (ii) of this paragraph 6(g) shall be given in the manner and
at the time that such notice is given to the holders of Common Stock.  Without
limiting the obligations of the Corporation to provide notice of corporate
actions hereunder, the failure to give the notice required by this paragraph
6(g) or any defect therein shall not affect the legality or validity of any such
corporate action of the Corporation or the vote upon such action.

          (h)  Procedures for Conversion. Before any holder of Convertible
               -------------------------
Preferred Stock shall be entitled to convert the same into Series A Common
Stock, Series B Common Stock or Series K Common Stock, as applicable (or, in the
case of the Mandatory Conversion, before any holder of Convertible Preferred
Stock so converted shall be entitled to receive a certificate or certificates
evidencing the shares of Series A Common Stock, Series B Common Stock or Series
K Common Stock, as applicable, issuable upon such conversion), such holder shall
surrender the certificate or certificates for such Convertible Preferred Stock
at the office of the Corporation or at the office of the transfer agent for the
Convertible Preferred Stock, which certificate or certificates, if the
Corporation shall so request, shall be duly endorsed to the Corporation or in
blank or accompanied by proper instruments of transfer to the Corporation or in
blank (such endorsements or instruments of transfer to be in form satisfactory
to the Corporation), and shall give written notice to the Corporation at said
office that such holder elects to convert all or a part of the shares
represented by said certificate or certificates (or, in the case of the
Mandatory Conversion, that such holder is surrendering the same) in accordance
with the terms of this paragraph 6, and shall state in writing therein the name
or names in which such holder wishes the certificates for Series A Common Stock,
Series B Common Stock or Series K Common Stock, as applicable, to be issued.
Every such notice of election to convert shall constitute a contract between the
holder of such Convertible Preferred Stock and the Corporation, whereby the
holder of such Convertible Preferred Stock shall be deemed to subscribe for the
amount of Series A Common Stock, Series B Common Stock or Series K Common Stock,
as applicable, which such holder shall be entitled to receive upon conversion of
the number of shares of Convertible Preferred Stock to be converted, and, in
satisfaction of such subscription, to deposit the shares of Convertible
Preferred Stock to be converted, and thereby the Corporation shall be deemed to
agree that the surrender of the shares of Convertible Preferred Stock to be
converted shall constitute full payment of such subscription for Series A Common
Stock, Series B Common Stock or Series K Common Stock, as applicable, to be
issued upon such conversion. The Corporation will as soon as practicable after
such deposit of a certificate or certificates for Convertible Preferred Stock,
accompanied by the written notice and the statement above prescribed, issue and
deliver at the office of the Corporation or of said transfer agent to the 

                                       23
<PAGE>
 
Person for whose account such Convertible Preferred Stock was so surrendered, or
to his nominee(s) or, subject to compliance with applicable law, transferee(s),
a certificate or certificates for the number of full shares of Series A Common
Stock, Series B Common Stock or Series K Common Stock, as applicable, to which
such holder shall be entitled, together with cash in lieu of any fraction of a
share as hereinafter provided together with an amount in cash equal to the full
amount of any cash dividend declared (or required to be declared) on the
Convertible Preferred Stock which, as of the date of such conversion, remains
unpaid (provided that the Corporation will use commercially reasonable efforts
to make such delivery within two Business Days after such deposit and such
notice and statement). If surrendered certificates for Convertible Preferred
Stock are converted only in part, the Corporation will issue and deliver to the
holder, or to his nominee(s), without charge therefor, a new certificate or
certificates representing the aggregate of the unconverted shares. Such
conversion shall be deemed to have been made as of the date of such surrender of
the Convertible Preferred Stock to be converted or immediately prior to the
Mandatory Conversion; and the Person or Persons entitled to receive the Series A
Common Stock, Series B Common Stock or Series K Common Stock, as applicable,
issuable upon conversion of such Convertible Preferred Stock shall be treated
for all purposes as the record holder or holders of such Series A Common Stock,
Series B Common Stock or Series K Common Stock, as applicable, on such date;
provided, however, that the conversion may, at the option of any holder
surrendering Convertible Preferred Stock for conversion, be conditioned upon the
IPO or upon notice by such holder to the Corporation of the occurrence of any
other specified event, as the case may be.

          (i)  Transfer Taxes.  The issuance of certificates for shares of
               --------------
Series A Common Stock, Series B Common Stock or Series K Common Stock, as
applicable, upon conversion of shares of Convertible Preferred Stock shall be
made without charge for any issue, stamp or other similar tax in respect of such
issuance, provided, however, if any such certificate is to be issued in a name
other than that of the registered holder of the share or shares of Convertible
Preferred Stock converted, the Person or Persons requesting the issuance thereof
shall pay to the Corporation the amount of any tax which may be payable in
respect of any transfer involved in such issuance or shall establish to the
satisfaction of the Corporation that such tax has been paid.

          (j)  Reservation of Shares.  The Corporation shall reserve and keep
               ---------------------
available at all times thereafter, solely for the purpose of issuance upon
conversion of the outstanding shares of Convertible Preferred Stock, such number
of shares of Series A Common Stock, Series B Common Stock and Series K Common
Stock as shall be issuable upon the conversion of all outstanding shares of
Convertible Preferred Stock, provided that nothing contained herein shall be
construed to preclude the Corporation from satisfying its obligations in respect
of the conversion of the outstanding shares of Convertible Preferred Stock by
delivery of shares of Series A Common Stock, Series B Common Stock or Series K
Common Stock which are held in the treasury of the Corporation. The Corporation
shall take all such corporate and other actions as from time to time may be
necessary to insure that all shares of Series A Common Stock, Series B Common
Stock and Series K Common Stock issuable upon conversion of shares of
Convertible Preferred Stock at the Conversion Rate in effect from time to time
will, upon issue, be duly and validly authorized and issued, fully paid and
nonassessable and free of any preemptive or similar rights.

          (k)  Retirement of Convertible Preferred Stock. All shares of
               -----------------------------------------
Convertible Preferred Stock received by the Corporation upon conversion thereof
into Series A Common Stock, Series B Common Stock or Series K Common Stock, as
applicable, shall be retired and shall not be reissued.

          (l)  Payment in Lieu of Fractional Shares. The Corporation shall not
               ------------------------------------
be required to issue fractional shares of Series A Common Stock, Series B Common
Stock or Series K Common Stock or scrip upon conversion of the Convertible
Preferred Stock. As to any final fraction of a share of Series A Common Stock,
Series B Common Stock or Series K Common Stock, as applicable, which a holder of
one or more shares of Convertible Preferred Stock would otherwise be entitled to
receive upon conversion of such shares in the same transaction, the Corporation
shall pay a cash adjustment in respect of such final fraction in an amount equal
(I) if the Corporation is a Public Company, to the same fraction of the market
value of a full share of Series A Common Stock or (II) if the Corporation is not
a Public Company, to the same fraction of the fair market value of a share of
Series A Common Stock, Series B Common Stock or Series K Common Stock, as
applicable, as determined in good faith by the Board of Directors. For the
purpose of any computation under this paragraph 6 requiring the determination of
the current market value per share of Series A Common Stock, if the Corporation
is a Public Company, such value at any date shall be deemed to be the average of
the daily closing prices for a share of Series A Common Stock for the ten (10)
consecutive trading days before the day in question. The closing price for each
day shall be the last reported sale price regular way or, in case no such
reported sale takes place on such day, the average of the reported closing bid
and asked prices regular way, in either case on the composite tape, or if the
shares of Series A Common Stock are not quoted on the composite tape, on the
principal United States securities exchange registered under the Exchange Act,
on which the shares of Series A Common Stock are listed or admitted to trading,
or if they are not listed or admitted to trading on any such exchange, the last
reported sale price (or the average of the quoted closing bid and asked prices
if there were no reported sales) as reported by the National Association of
Securities Dealers Automated Quotation System ("NASDAQ") or any comparable
system, or if the Series A Common Stock is not quoted on Nasdaq or any
comparable system, the average of the closing bid and asked prices as furnished
by any member of the National Association of Securities Dealers, Inc. selected
from time to time by the Corporation for that purpose or, in the absence of such
quotations, such other method of determining market value as the Board of
Directors shall from time to time deem to be fair.


          (m)  Regulatory Matters. If any shares of Series A Common Stock,
               ------------------
Series B Common Stock or Series K Common Stock which would be issuable upon
conversion of shares of Convertible Preferred Stock require registration with or
approval of any governmental authority before such shares may be issued upon
conversion, the Corporation will in good faith and as expeditiously as possible
cause such shares to be duly registered or approved, as the case may be. Without
limiting the foregoing, if the conversion of shares of Convertible Preferred
Stock shall be subject to the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended, and the rules and regulations promulgated thereunder (the "HSR
ACT AND RULES"), the Corporation shall promptly comply with any applicable
filing or notice requirements under the HSR Act and Rules and use its reasonable
commercial efforts to furnish the information required in connection therewith
to the Federal Trade Commission and the Antitrust Division of the Department of
Justice. If applicable, the Corporation shall use its 

                                       25
<PAGE>
 
reasonable commercial efforts to list (i) the shares of Series A Common Stock
issuable upon conversion of the Series A Preferred Stock, (ii) the shares of
Series A Common Stock issuable upon conversion of the Series K Common Stock
required to be delivered upon conversion of the Series K Preferred Stock, and
(iii) the shares of Series A Common Stock issuable upon conversion of the Series
B Common Stock required to be delivered upon conversion of the Series T
Preferred Stock, in each case prior to delivery of such shares of Series A
Common Stock upon such conversion, on the principal national securities exchange
(including, but not limited to, the Nasdaq National Market) on which the
outstanding Series A Common Stock is listed at the time of such delivery.

          Preferred Stock, the Series AX Preferred Stock, the Series K Preferred

          Stock present in person or represented by proxy at such meeting and

          quorum for such election at such meeting, and the absence of a quorum
          of holders of shares other than the Series AM Preferred Stock, Series
          AT Preferred Stock, Series AX Preferred Stock, Series K Preferred
          Stock or Series T Preferred Stock shall not prevent the election of

          class or series of stock which lack a quorum shall have power to
          adjourn the meeting for the election of directors which such class or
          series is entitled to elect, from time to time, without notice

          office of a Preferred Stock Director occurring during the
          effectiveness of the applicable provisions of paragraph 7(b)(i) shall
          be filled solely by the 

                                       28
<PAGE>
 
          holders of the series of Convertible Preferred Stock entitled to elect
          such Preferred Stock Director by vote of such holders as provided in
          paragraph 7(b)(iii) above at a meeting called for such purpose or by
          written consent of such holders given in accordance with paragraph
          7(b)(vi) below.

               (v)   A Preferred Stock Director elected by a specified series of
          Convertible Preferred Stock may be removed without cause by the vote
          or by written consent of the holders of a majority of the outstanding
          shares of such series of Convertible Preferred Stock which elected
          such Preferred Stock Director. Any vacancy in the office of a
          Preferred Stock Director shall be filled by the affirmative vote of
          the holders of a majority of the outstanding shares of the applicable
          series of Convertible Preferred Stock entitled to elect the Preferred
          Stock Director so removed at a meeting, which may be the same meeting
          at which the removal of such Preferred Stock Director was voted upon,
          or by written consent of the holders of such series of Preferred Stock
          given in accordance with paragraph 7(b)(vi) below. Any director
          elected to fill a vacancy shall serve the same remaining term as that
          of his or her predecessor and until his or her successor has been
          chosen and has qualified.

               (vi)  With respect to actions by the holders of the Series AM
          Preferred Stock, the Series AT Preferred Stock, the Series AX
          Preferred Stock, the Series K Preferred Stock or the Series T
          Preferred Stock upon those matters on which such holders are entitled
          to vote as a separate series, such actions may be taken without a
          meeting, without prior notice and without a vote, if a consent or
          consents in writing, setting forth the action so taken, shall be
          signed by the holders of outstanding shares of Series AM Preferred
          Stock, Series AT Preferred Stock, Series AX Preferred Stock, Series K
          Preferred Stock or Series T Preferred Stock, as the case may be,
          having not less than the minimum number of votes that would be
          necessary to authorize or take such action at a meeting at which all
          shares of such series of Convertible Preferred Stock entitled to vote
          thereon were present and voted, and shall be delivered to the
          Corporation as provided in the DGCL. Notice shall be given in
          accordance with the applicable provisions of the DGCL of the taking of
          corporate action without a meeting by less than unanimous written
          consent.

               (vii) The right of the holders of Convertible Preferred Stock to
          elect the Preferred Stock Directors shall be in addition to their
          right to vote, on an as-converted basis (in the case of the Series A
          Preferred Stock into Series A Common Stock, in the case of Series K
          Preferred Stock into Series K Common Stock and in the case of the
          Series T Preferred Stock into Series B Common Stock), with the holders
          of the Common Stock and any other series of Series Preferred Stock so
          entitled to vote, together as a single class, in the election of all
          other members of the Board of Directors (other than the Series B and
          Series K Common Stock Directors).

          to effect any adverse change in the voting powers, designations,

          Preferred Stock in the same manner, without the consent of the holders

                  LIMITATION ON LIABILITY AND INDEMNIFICATION

     1.   Limitation On Liability.
          ------------------------

          To the fullest extent permitted by the DGCL as the same exists or may
hereafter be amended, a director of the Corporation shall not be liable to the
Corporation or any of its stockholders for monetary damages for breach of
fiduciary duty as a director. Any repeal or modification of this paragraph 1
shall be prospective only and shall not adversely affect any limitation, right
or protection of a director of the Corporation existing at the time of such
repeal or modification.

         (a)  Right to Indemnification. The Corporation shall indemnify and hold

harmless, to the fullest extent permitted by applicable law as it presently
exists or may hereafter be amended, any Person who was or is made or is
threatened to be made a party or is otherwise involved in any action, suit or
proceeding, whether civil, criminal, administrative or investigative (a

or was serving at the request of the Corporation as a director, officer,
employee or agent of another corporation or of a partnership, joint venture,
trust, enterprise or nonprofit entity, including service with respect to
employee benefit plans, against all liability and loss suffered and expenses
(including attorneys' fees) reasonably incurred by such Person. Such right of
indemnification shall inure whether or not the claim asserted is based on
matters which antedate the adoption of this Section C. The Corporation shall be
required to indemnify a Person in connection with a proceeding (or part thereof)
initiated by such Person only if the proceeding (or part thereof) was authorized
by the Board of Directors of the Corporation.

          (b)  Prepayment of Expenses. The Corporation shall pay the expenses
               ----------------------

its final disposition, provided, however, that the payment of expenses incurred
by a director or officer in advance of the final disposition of the proceeding
shall be made only upon receipt of an undertaking by the director or officer to
repay all amounts advanced if it should be ultimately determined that the
director or officer is not entitled to be indemnified under this paragraph or
otherwise.

          (c)  Claims. If a claim for indemnification or payment of expenses
               ------  
under this paragraph is not paid in full within 60 days after a written claim
therefor has been received by the Corporation, the claimant may file suit to
recover the unpaid amount of such claim and, if successful in whole or in part,
shall be entitled to be paid the expense of prosecuting such claim. In any such
action the Corporation shall have the burden of proving that the claimant was
not entitled to the requested indemnification or payment of expenses under
applicable law.

          (d)  Non-Exclusivity of Rights. The rights conferred on any Person by
               -------------------------
this paragraph shall not be exclusive of any other rights which such Person may
or hereafter

                                       43
<PAGE>
 
acquire under any statute, provision of this Certificate, the Bylaws of the
Corporation, agreement, vote of stockholders or disinterested directors or
otherwise.

          (e)  Other Indemnification. The Corporation's obligation, if any, to
               ---------------------
indemnify any Person who was or is serving at its request as a director,
officer, employee or agent of another corporation, partnership, joint venture,
trust, enterprise or nonprofit entity shall be reduced by any amount such Person
may collect as indemnification from such other corporation, partnership, joint
venture, trust, enterprise or nonprofit entity.

     3.   Amendment or Repeal.
          --------------------
 
          Any repeal or modification of the foregoing provisions of this Section
C shall not adversely affect any right or protection hereunder of any Person in
respect of any act or omission occurring prior to the time of such repeal or
modification.

          1.3  Terms of Interpretation Generally.  The definitions in Section 
               ---------------------------------                             
1.1 and elsewhere in this Agreement shall apply equally to both the singular and
plural forms of the terms defined.  Whenever the context may require, any
pronoun shall include the corresponding masculine, feminine and neuter forms.
The words "include," "includes" and "including" shall be deemed to be followed
by the phrase "without limitation." The words "herein," "hereof," "hereto" and
"hereunder" and words of similar import refer to this Agreement in its entirety
and not to any part hereof unless the context shall otherwise require.  All
references herein to Sections shall be deemed references to Sections of this
Agreement unless the context shall otherwise require.  Unless the context shall
otherwise require, any references to any agreement or other instrument or
statute or regulation are to it as amended and supplemented from time to time
(and, 

                                     -19-
<PAGE>
 
in the case of a statute or regulation, to any corresponding provisions of
successor statutes or regulations). Any reference in this Agreement to a "day"
or number of "days" (without the explicit qualification of "Business") shall be
interpreted as a reference to a calendar day or number of calendar days. If any
action or notice is to be taken or given on or by a particular calendar day, and
such calendar day is not a Business Day, then such action or notice shall be
deferred until, or may be taken or given on, the next Business Day. The
provisions of Section 1.2 are informational in nature and do not constitute
substantive provisions of this Agreement.

                               STOCKHOLDER GROUPS
                               ------------------

          2.1  Stockholder Groups; Ownership Provisions.  (a) All actions and
               ----------------------------------------                      
determinations by, and all notices by or to, a Stockholder Group or any member
thereof shall be deemed validly taken or made (in the case of actions or
determinations) or given (in the case of notices) if taken, made or given, as
the case may be,  by or to TCI Sub (in the case of the TCI Stockholder Group),
by or to KPCB (in the case of the KPCB Stockholder Group),  by or to Cox Sub (in
the case of the Cox Stockholder Group); or  by or to Comcast Sub (in the case of
the Comcast Stockholder Group), and shall be binding upon all members of any
such Stockholder Group for all purposes of this Agreement.  If any of TCI Sub,
KPCB, Cox Sub or Comcast Sub (or any successor thereto pursuant to this
sentence) is no longer in existence or no longer beneficially owns any Company
Securities, but its Stockholder Group (or a successor or permitted assign
thereof) continues to have rights and/or obligations hereunder, then such
Stockholder shall appoint one such continuing entity as its replacement pursuant
to the immediately preceding sentence; provided, that if no such appointment is
                                       --------                                
made, such Stockholder's Parent shall be deemed to be such replacement.  Each
member of another Stockholder Group may rely upon the notification or advice of
a Stockholder with respect to any matter relating to the members of such
Stockholder's Stockholder Group.  To the extent any party to this Agreement is
required to take any action hereunder, it agrees to use its reasonable best
efforts to cause the other members of its Stockholder Group to take such action.

               (b) Except as expressly permitted or required by this Agreement,
(i) each Stockholder shall be the record and beneficial owner of the Company
Securities set forth opposite its name on Schedule I, in each case free and
clear of any liens, claims or encumbrances, and (ii) no Stockholder shall enter
into any agreement or arrangement (x) with respect to the exercise of its rights
to designate Stockholder Designees or to request the removal of a Stockholder
Designee pursuant to the Charter or this Agreement or (y) with respect to the
voting by its Stockholder Designees in connection with any of the matters set
forth in SECTION B(4) of Article V of the Charter, other than, with respect to
clauses (x) or (y) of this clause (ii), an agreement or arrangement solely among
Stockholders that are included in the same Stockholder Group.

               (c) If at any time during the term of this Agreement any
Stockholder Group ceases to own its applicable Eligible Stockholder Amount, the
Stockholder that is a member of the Stockholder Group that ceased to own such
amount, on behalf of its associated Stockholder Group, shall promptly notify the
other Stockholders in writing of such fact and, unless each other Stockholder
shall elect by written notice delivered to such Stockholder to waive such
requirement in respect of such Stockholder Group (which waiver shall be binding
and shall remain applicable to the Stockholder Group that ceased to own such
amount so long as the ownership of Company Securities by such Stockholder Group
does not decrease further (subject in the case of each such further decrease, to
giving another such notice and receiving an additional or further waiver)), such
Stockholder and its Stockholder Group shall cease to be an Eligible Stockholder
and shall (x) cease to have any rights granted to or exercisable by an Eligible
Stockholder pursuant to this Agreement, the Master Distribution Agreement or the
LCO Agreement and (y) remain obligated with respect to the performance of its
obligations hereunder and thereunder. Any subsequent acquisition of securities
of the Company by or through any Person which is or becomes a member of a
Stockholder Group which has ceased to be an Eligible Stockholder shall not
entitle any such Stockholder Group to reinstatement as an Eligible Stockholder.

               (d) Each Stockholder covenants and agrees that, (i) in the event
that any Ultimate Parent acquires direct or indirect beneficial ownership of
Voting Stock (other than Company Securities) subsequent to the execution of this
Agreement, which ownership is held in or through any Person which is not a party
to this Agreement, such Ultimate Parent shall cause the Person so acquiring such
Voting Stock to become a party to this Agreement solely for the purpose of
committing to vote all shares of Voting Stock held by such Person and its
Controlled Affiliates in accordance with the terms of this Agreement relating
specifically to voting (and such Person shall execute and deliver an appropriate
instrument reflecting such commitment), and (ii each member of a Stockholder
Group that is not a party to this Agreement may not acquire Company Securities
or Voting Stock unless it becomes a party to this Agreement.

               (e) In the event of any Indirect Transfer of Company Securities
resulting from a Qualified Spin Off Transaction, each Parent agrees, as a
condition to such Qualified Spin Off Transaction, to cause the Spin Off Parent
resulting therefrom to become a party to this Agreement.  In connection with any
such Qualified Spin Off Transaction, such Parent shall assign all of its rights
and obligations hereunder to such Spin Off Parent and provided that such Parent
has not retained any beneficial ownership in the Company Securities (through the
ownership of the equity securities of the applicable Stockholder or a member of
such Stockholder's Stockholder Group or of such Spin Off Parent), such Parent
shall be released from all of its obligations hereunder; provided, however, that
                                                         --------  -------      
no such assignment shall release any Parent or Ultimate Parent from their
respective obligations pursuant to the Master Distribution Agreement.

          3.1  Voting Generally.  (a)  When any action is required to be taken
               ----------------                                               
by a Stockholder pursuant to this Agreement, the Charter or the Bylaws, such
Stockholder agrees to take all steps reasonably necessary to implement such
action including, without limitation, voting at any meeting of stockholders all
shares of Voting Stock held by such Stockholder in favor of such action, and/or
executing or causing to be executed, as promptly as practicable, a consent in
writing to the taking of such action.  Any agreement by a Stockholder to vote
all Voting Stock held by such Stockholder in a certain manner shall be deemed,
in each instance, to include an agreement by such Stockholder to use its
commercially reasonable efforts to take all actions necessary to call, or to
cause the Company and the appropriate officers and directors of the Company to
call, as promptly as practicable, a special or annual meeting of stockholders to
consider such action (and such Stockholder shall thereafter attend any such
annual or special meeting in person or by proxy), or to cause a written consent
to the taking of such action to be circulated among the stockholders of the
Company (and to execute and deliver any such consent to such action).  Except as
expressly provided herein, any provision in this Agreement, the Charter or the
Bylaws requiring a Stockholder to cause the Board to take any action shall
require such Stockholder (i) to instruct each of its Stockholder Designees to
vote in favor of such action or to consent in writing to the taking of such
action and (ii) to take such other actions (including without limitation the
removal and replacement of its Stockholder Designees) as may be reasonably
necessary to cause such action to be taken.

               (b) Each Stockholder hereby agrees that the Person or Persons
that it designates and/or elects or appoints as a Stockholder Designee shall be
at the time of such designation and election and so long as such Person remains
a Stockholder Designee, an officer, director, employee or partner of a member of
its Stockholder Group. Each Stockholder agrees to fill promptly any vacancy on
the Board resulting from the death, disability, retirement, resignation, or
removal of its Stockholder Designees.

               (c) Except as expressly provided herein, each Stockholder shall
be entitled to vote all of its shares of Voting Stock as it shall determine in
its sole discretion, including, but not limited to, for the election of such
Common Stock Directors as it shall determine in its sole discretion.

               (d) In the event that the restrictions of Section 203 of the DGCL
become applicable to the Company, each Stockholder agrees to use its reasonable
best efforts to cause its Stockholder Designees to approve, for purposes of
Section 203 of the DGCL, any Transfers or Indirect Transfers of Company
Securities by or to any Stockholder Group (including its affiliates and
associates) which are otherwise Permitted Transfers hereunder.

          3.2  Election of CEO to the Board.  Each Stockholder hereby agrees to
               ----------------------------                                    
vote all Voting Stock held by such Stockholder to cause the CEO selected in
accordance with the provisions of SECTION B(4)(a)(5) of Article V of the Charter
to be elected to the Board as a Common Stock Director.

          3.3  Designation and Election of Series B Common Directors.  (a)  Upon
               -----------------------------------------------------            
the Mandatory Conversion, each Stockholder beneficially owning (or having the
right to acquire upon consummation of the conversion thereof) shares of Series B
Common Stock shall vote all such shares of Series B Common Stock in favor of the
election of each of the Selected Directors in office immediately prior to such
Mandatory Conversion (including any Person to be elected or appointed to fill
any vacancy among the Selected Directors resulting from the death, disability,
retirement, resignation, or removal of a Selected Director of a Stockholder
Group, which Stockholder Group was prior to such Mandatory Conversion entitled
to elect such Selected Director, but excluding any Selected Director whose
Stockholder Group has ceased to become entitled to elect such a director, but
who has not resigned or been removed or otherwise ceased to be a director at the
time of such Mandatory Conversion) as Series B Common Directors.

               (b) Following the Mandatory Conversion, (i) Comcast Sub shall be
entitled to designate, in its sole discretion, one Series B Common Director so
long as the Comcast Stockholder Group beneficially owns at least 2,500,000
shares of Common Stock (which are Company Securities), (ii) Cox Sub shall be
entitled to designate, in its sole discretion, one Series B Common Director so
long as the Cox Stockholder Group beneficially owns at least 2,500,000 shares of
Common Stock (which are Company Securities) and (iii) TCI Sub shall be entitled
to designate, in its sole discretion: (x) three Series B Common Directors so
long as the TCI Stockholder Group beneficially owns at least 3,850,000 shares of
Series B Common Stock (which are Company Securities); (y) two Series B Common
Directors in the event that the TCI Stockholder Group ceases to beneficially own
at least 3,850,000 shares of Series B Common Stock but owns at least 3,175,000
shares of Series B Common Stock (which are Company Securities); and (z) one
Series B Common Director in the event that the TCI Stockholder Group ceases to
beneficially own at least 3,175,000 shares of Series B Common Stock, but owns at
least 2,500,000 shares of Common Stock (which are Company Securities) (such
number of shares, in each case, as appropriately adjusted to give effect to any
stock splits, reverse stock splits, stock dividends, recapitalizations and the
like occurring after the Closing); provided, however, that in no event shall the
                                   --------  -------                            
number of Series B Common Directors to be designated by each Stockholder
pursuant to this Section 3.3(b) exceed the number of Stockholder Designees to
which such Stockholder was entitled immediately prior to the Mandatory
Conversion, and the number of Stockholder Designees to which such Stockholder
shall be entitled pursuant to this Section 3.3(b) shall be appropriately
adjusted to reflect such reduction.  Each Stockholder shall provide written
notice of its Stockholder Designees to each other Stockholder not less than two
(2) days prior to any meeting of Stockholders of the Company being held for the
purpose of electing Series B Common Directors.

                                     -23-

               (c) So long as the holders of the Series B Common Stock are
entitled to elect Series B Common Directors in accordance with the Charter, each
member of a Stockholder Group beneficially owning shares of Series B Common
Stock shall (i) vote all of its shares of Series B Common Stock at any annual or
special meeting of Stockholders at which Series B Common Directors are to be
elected in favor of, or shall duly consent in writing (in accordance with the
Charter) to, the election of the Stockholder Designees, designated in accordance
with paragraph (b) above and (ii) use its best efforts to take all other
necessary actions (including using its best efforts to cause the Company to call
a special meeting of stockholders), in order to give effect to the provisions of
this Section 3.3. The Company agrees that it will take all actions that are
necessary and within its power in order to give effect to the provisions of this
Section 3.3(c).

          3.4  Removal of Special Directors and Series K Director.  (a)
               --------------------------------------------------       
Following the Mandatory Conversion, each Stockholder owning Series B Common
Stock shall vote all of its shares of Series B Common Stock in favor of, or
shall duly consent in writing (in accordance with the Charter) to, the removal
(with or without cause) of any Series B Common Director designated by a
Stockholder pursuant to Section 3.3(b) if (i) the Stockholder who designated
such Series B Common Director requests such removal by notice to the other
Stockholders or (ii) the Stockholder Group of the Stockholder which designated
such Series B Common Director ceases to beneficially own the minimum number of
Company Securities as is required in accordance with Section 3.3(b) hereof in
order to entitle such Stockholder to designate  the number of its Stockholder
Designees then serving as its designees on the Board pursuant to Section 3.3(b);
provided, that so long as TCI Sub is entitled to elect more than one Series B
- --------                                                                     
Common Director, upon any reduction in the number of Stockholder Designees to
which it is entitled, TCI Sub shall be entitled to select the identity of those
of its Series B Common Directors to be removed.

               (b) In the event that any Stockholder ceases to be entitled to
designate a Selected Director or Series K Director, as the case may be, or in
the case of TCI Sub, becomes entitled to elect a lesser number of Selected
Directors, such Stockholder shall immediately cause its Stockholder Designee
then serving as a Selected Director or Series K Director to resign from the
Board (or in the case of TCI Sub, cause such of its Stockholder Designees on the
Board to resign). Upon the occurrence of an event described in clause (ii) of
Section 3.4(a) the applicable Stockholder shall immediately use its best efforts
to cause its Series B Common Director in the case of Comcast Sub or Cox Sub, or
an appropriate number of its Series B Common Directors in the case of TCI Sub,
to resign from the Board of Directors.  If such Stockholder Designee does not
promptly resign from the Board, each Stockholder owning Series B Common Stock
agrees to vote all such shares in favor of the removal of such Stockholder
Designee.  Upon the occurrence of any event decreasing the number of Series B
Common Directors each Stockholder agrees to take such actions, and to use its
best efforts to cause its Stockholder Designees which are members of the Board
to take such actions, as may be necessary in order to effect a permanent
reduction in the number of such Series B Common Directors, including but not
limited to the voting (or execution of a written consent) of all shares of
Voting Stock beneficially owned by it in favor of an amendment to the Charter so
reducing the number of such Series B Common Directors.  Upon 

                                     -24-
<PAGE>
 
any such reduction in the total number of Series B Common Directors entitled to
be elected by the Stockholders upon or following the Mandatory Conversion, the
holders of the Series B Common Stock shall then be entitled to elect a total
number of Series B Common Directors equal to the then total authorized number of
Series B Common Directors after giving effect to such reduction.
 
          3.5  Vacancies Among the Series B Common Directors.  Following the
               ---------------------------------------------                
Mandatory Conversion, if there shall exist or occur any vacancy among the Series
B Common Directors as a result of  death, disability, retirement, resignation,
removal (with or without cause) or otherwise (other than a vacancy caused by the
resignation and/or removal of a Series B Common Director in connection with a
reduction of the total number of Series B Common Directors to be elected by the
holders of the Series B Common Stock), an individual to fill such vacancy shall
be designated by the Stockholder whose Stockholder Designee's death, disability,
retirement, resignation or removal has caused such vacancy to occur.  Notice of
such designation shall be given and such individual shall be elected in the
manner provided in Section 3.3(c) above.

          3.6  Outside Directors.  Following the IPO, the Stockholders agree to
               -----------------                                               
take such actions as may be reasonably necessary to cause individuals who will
qualify as Outside Directors (as defined in the Charter) to be elected as Series
A Common Stock Directors (as defined in the Charter) (for so long as the holders
of the Series A Common Stock, voting separately as a class, are entitled to
elect such directors).

          3.7  Conflicting Charter and Bylaws.  Each Stockholder agrees to vote
               ------------------------------                                  
all of its shares of Voting Stock entitled to vote, and to take all other
actions necessary, to ensure that the Charter and Bylaws of the Company
facilitate and do not at any time prohibit the actions contemplated by this
Agreement.

          3.8  Special Voting Provisions.  (a)  Each Stockholder agrees that, in
               -------------------------                                        
the event that at any time there are less than two Special Directors who have
not been elected by TCI or its Controlled Affiliates, it will use its reasonable
best efforts to cause all of its Stockholder Designees on the Board of Directors
not to vote for or execute a written consent approving the taking of any action
by the Company with respect to (i) any matter identified in SECTION B(4) of
Article V of the Charter as requiring a Supermajority Vote or (ii) following the
IPO any Related Party Transaction, unless in each case, the taking of such
action by the Company is approved by all Special Directors.

               (b) In the event that the taking of any action with respect to
the matters set forth in Section C(7)(c) of Article IV of the Charter or SECTION
B(4) of Article V of the Charter requires (in addition to, in the case of
SECTION B(4) of Article V of the Charter, the approval by a Supermajority Vote
or Unanimous Vote of the Special Directors and the Series K Director, as
applicable) the approval of one or more classes or series of the capital stock
of the Company, each Stockholder Group agrees to vote all shares of Voting Stock
owned by such Stockholder Group and entitled to vote thereon in a manner
consistent with the action approved 

                                     -25-
<PAGE>
 
by the Board (in the case of Section C(7)(c) of Article IV of the Charter) or
the applicable percentage of the Special Directors and the Series K Director (in
the case of SECTION B(4) of Article V of the Charter).

               (c) Notwithstanding anything contained herein to the contrary,
the KPCB Affiliates shall be entitled to vote their shares of Series K Preferred
Stock against any of the KPCB Special Voting Matters.

               (d) Each Stockholder Group agrees to vote all shares of Voting
Stock held by it in a manner consistent with the implementation of any unanimous
decision of all of the Special Directors.

          3.9  Certain Amendments In Connection with the IPO.  Upon the
               ---------------------------------------------           
consummation of the IPO, the parties agree to discuss any amendments to this
Agreement reasonably necessary to reflect the Company's status as a Public
Company.

          3.10  .Com Committee.  (a)  The Company acknowledges and agrees that
                --------------                                                
its policy and practices with respect to its willingness to negotiate and enter
into all .Com Agreements and all Promotional Agreements with content providers
that meet the Company's reasonable standards relating to obscene or offensive
material, is one of openness and non-exclusion, regardless of the identity of
such content provider and its relationship with the Company, and that it is in
the best interest of the Company and its stockholders for the Company to enter
into as many such agreements as is practicable.  The terms and conditions of
 .Com Agreements and Promotional Agreements shall not take into account the
identity of the Affiliates or Associates of such content provider nor shall the
identity of the Affiliates or Associates of any such content provider result in
either the exclusion of such content provider or such content provider gaining
promotion at the expense of others. Therefore, because the Parents and the Cable
Parents each have significant investments in a wide variety of content providers
and do not want such content providers' ability to obtain carriage and promotion
on the @Home Services to be unfairly advantaged or disadvantaged, the parties
have determined that the entering into of .Com and Promotional Agreements shall
not be considered Related Party Transactions regardless of the ownership of such
content provider or its relationship with any Stockholder or such Stockholder's
Related Party Affiliates, but that the entering into of such agreements shall be
governed by the procedure set forth in the Charter.

               (b) Except to the extent determined to the contrary by the
unanimous vote (or written consent) of all Special Directors as provided in the
following sentence, each Stockholder agrees that it will use its reasonable best
efforts to cause its Stockholder Designees on the Board to vote against any (i)
amendment, repeal, supplement or other modification of any action or
determination made by the .Com Committee, (ii) removal of any member of the .Com
Committee, (iii) amendment of any of the provisions of the Charter or the Bylaws
with respect to the .Com Committee or (iv) dissolution or termination of the
 .Com Committee to the extent such matters are presented to the Board for its
approval, adoption, ratification or confirmation. In the event that the Special
Directors determine, by a unanimous vote (or written consent) to (i) 

                                     -26-
<PAGE>
 
rescind, amend, repeal, supplement or otherwise modify any action or
determination made by the .Com Committee, (ii) remove any member of the .Com
Committee, (iii) amend any of the provisions of the Charter or the Bylaws with
respect to the .Com Committee or (iv) dissolve or terminate the .Com Committee,
each Stockholder agrees to use its reasonable best efforts to cause its
Stockholder Designees on the Board to vote in favor of any such unanimous
determination by the Special Directors.

               (c) Each Stockholder agrees that (i) immediately upon the
consummation of the transactions contemplated hereby, it will use its reasonable
best efforts to cause its Stockholder Designees on the Board to appoint as the
initial members of the .Com Committee: Thomas A. Jermoluk, L. John Doerr,
William R. Hearst, III and James Barksdale, (ii) upon the appointment of any
successor to the current CEO and such person's election as a director, it will
use it reasonable best efforts to cause its Stockholder Designees to appoint
such successor CEO as a member of the .Com Committee, and (iii) it will use its
reasonable best efforts to cause its Stockholder Designees to appoint any
additional director unanimously selected by the Special Directors as a member of
the .Com Committee. Notwithstanding the foregoing, following the initial
appointment of the members of the .Com Committee pursuant to this Section
3.10(c), nothing herein contained will be deemed to require any Stockholder or
its Stockholder Group to vote its shares of Voting Stock in favor of the
continued election as a director of any incumbent member of the .Com Committee.

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

          4.1  General Restrictions on Transfer.  (a)  Prior to the earliest to

occur of (i) the tenth anniversary of the Execution Date, (ii the fifth
anniversary of the termination of the Restricted Period as to any Cable Parent
and (ii the sixth anniversary of the IPO, no Stockholder shall voluntarily or
involuntarily Transfer any Company Securities or make an Indirect Transfer of
Company Securities, except for a Permitted Transfer or a Permitted Disposition;
provided, however, notwithstanding anything to the contrary contained herein,
- --------  -------                                                            
that following the IPO, all restrictions upon Transfer set forth in this
Agreement (other than the restrictions relating to the conversion of Company
Securities set forth in Section 4.2) shall terminate and cease to be effective
as to any KPCB Constituents which have received or receive Company Securities
in a Transfer permitted by and in accordance with clause (vii) of the definition
of "Permitted Transfer" and as to Jim Clark.  The provisions of this Section 4.1
shall apply to each proposed Permitted Transfer or Permitted Disposition, and no
Stockholder shall consummate any Permitted Transfer or Permitted Disposition in
violation of the provisions of this Agreement.  Any purported Transfer of
Company Securities in violation of this Agreement shall be null and void and of
no force or effect, and the Company shall not record any such Transfer on its
stock transfer books.

               (b) During the period that Transfers are restricted pursuant to
Section 4.1(a), and without limiting any other requirements set forth elsewhere
herein, (i) in connection with any Permitted Transfer of any Company Securities
by any party hereto pursuant to clause (i)(y), (iii)(y), (vi), (vii) or (viii)
of the definition of "Permitted Transfer", such party shall (x) have complied
with the conversion requirements set forth in Section 4.2 (to the extent
applicable) prior to such Transfer and (y) give written notice to the Company
and each other Stockholder of such party's intention to effect such Transfer at
least five (5) Business Days prior to such Transfer and (ii) in connection with
any Indirect Transfer, such party shall give written notice at least two (2)
Business Days prior to such Indirect Transfer to the Company and each other
Stockholder. Each such notice shall describe the manner and circumstances of the
proposed Transfer in sufficient detail, and include any other information
required by the provisions of this Agreement applicable to such proposed
Transfer, and in the case of an Indirect Transfer pursuant to clause (ii), shall
include a certification by the transferor that such Transfer does not constitute
a Change of Control of a Stockholder.  In addition, in the event requested by
the Company (such requests not to be made more than once per calender year),
each Stockholder agrees to furnish to the Company and each other Stockholder a
certificate of such Stockholder certifying as to the number of Attributable
Shares owned by its Stockholder Group, the members of its Stockholder Group
having a direct or indirect interest in the Company Securities and the ownership
structure of such members of its Stockholder Group, the number and type of
shares of Voting Stock which are not Company Securities held by the members of
its Stockholder Group and such other matters related to its equity interest in
the Company as the Company shall reasonably request.

               (c) Each certificate evidencing Company Securities (i)
Transferred to a Permitted Transferee shall bear the restrictive legends set
forth in Section 5(a) and (b) of the Stock Purchase Agreement (unless such
legend may then be removed in accordance with the Registration Rights Agreement)
and (ii held by a party to this Agreement or transferred to a Permitted
Transferee who acquires Company Securities through a Transfer pursuant to
clauses (i)(y), (iii)(y), (iv), (vi), (vii) or (viii) of the definition of
"Permitted Transfer," shall also bear the restrictive legend set forth in
Section 5(c) of the Stock Purchase Agreement.

               (d) Notwithstanding anything to the contrary set forth in this
Agreement, provided that a Control Block Group complies with the provisions of
Sections 4.5 and 4.6, a Control Block Sale shall not be subject to the
restrictions set forth in Section 4.1(a), and any Unaffiliated Third Party
purchasing Company Securities in a Control Block Sale shall acquire such
securities free and clear of any obligations, and shall have no rights, under
this Agreement.

           4.2 Conversion of the Convertible Preferred Stock, the Series B
               -----------------------------------------------------------
Common Stock and the Series K Common Stock.
- ------------------------------------------ 

               (a) Except (i) as otherwise provided in this Section 4.2 and (ii
for any Transfer or Indirect Transfer in connection with a Control Block Sale or
Qualified Spin Off Transaction, no Stockholder shall Transfer any shares of
Convertible Preferred Stock, Series B Common Stock or Series K Common Stock
unless prior to the consummation of such Transfer it 

                                     -28-
<PAGE>
 
shall have converted any such shares into shares of Series A Common Stock;
provided, however, that no holder of Series B Common Stock shall convert any 
- --------  -------         
shares of Series B Common Stock into Series A Common Stock without first
complying with the provisions of clause (c) of this Section.

               (b) The provisions of subsection (a) above shall not be
applicable to any Transfer which is a Permitted Transfer in accordance with the
provisions of clauses (i)(y), (iii)(y), (iv), (v), (vi), (vii) or (viii) of the
definition of Permitted Transfer.

               (c) Prior to converting any shares of Series B Common Stock which
are Company Securities into shares of Series A Common Stock, any Stockholder
which owns Series B Common Stock shall deliver to the Cable Partners (other than
any Cable Partner which is proposing to convert shares of Series B Common Stock)
a written notice (a "Conversion Notice") of its intention to so convert such
                     -----------------                                      
shares of Series B Common Stock, which notice shall set forth the number of
shares of Series B Common Stock it intends to convert and shall serve as an
offer by such Stockholder to exchange (the "Series B Exchange") with the
                                            -----------------           
remaining Cable Partners such shares of Series B Common Stock proposed to be
converted for an equal number of shares of Series A Common Stock.  If any Cable
Partners wish to accept such offer for the Series B Exchange, such Cable
Partners shall deliver written notice of such acceptance to the Stockholder
desiring to convert, within two Business Days of receipt of the Conversion
Notice which notice shall set forth the number of shares of Series A Common
Stock such Cable Partners wish to exchange for shares of Series B Common Stock.
If the Cable Partners electing to participate in the Series B Exchange wish to
exchange in the aggregate a number shares of Series A Common Stock which exceeds
the number of shares of Series B Common Stock offered in the Conversion Notice,
then each Stockholder electing to participate shall be entitled to exchange a
number of shares of Series A Common Stock equal to the product of (x) a
fraction, the numerator of which is the number of shares of Series A Common
Stock (which are Company Securities) offered for exchange by such Cable Partner
and the denominator of which is the number of shares of Series A Common Stock
(which are Company Securities) offered for exchange by all Cable Partners
electing to participate and (y) the number of shares of Series B Common Stock
offered for exchange (in each case, determined on an as converted into Common
Stock basis).  In the event that the Cable Partners desiring to make the Series
B Exchange have not accepted such offer as to all shares of Series B Common
Stock so offered for exchange, any remaining Stockholder which is not a Cable
Partner shall be entitled to accept such offer as to any remaining shares of
Series B Common Stock and thereby participate in the Series B Exchange.  In the
event any holder of Series K Common Stock so elects to participate, such holder
shall, simultaneously with the Series B Exchange, convert into shares of Series
A Common Stock a number of shares of Series K Common Stock equal to the number
of shares of Series A Common Stock to be so exchanged. Such exchange shall be
consummated in accordance with the provisions of Section 11.9, as if it were a
purchase and sale of Company Securities and as if each Stockholder exchanging
securities were a seller, except that the provisions therein with respect to the
payment and delivery of a purchase price shall not be applicable.

<PAGE>
 
               (d) Each Stockholder owning shares of Series AM Preferred Stock,
Series AT Preferred Stock or Series AX Preferred Stock may convert such shares
into shares of Series A Common Stock; each Stockholder owning shares of Series K
Preferred Stock may convert such shares into shares of Series K Common Stock;
and each Stockholder owning shares of Series T Preferred Stock may convert such
shares into shares of Series B Common Stock, in each case, at such Stockholder's
option and without the consent of the other Stockholders.

               (e) In connection with the consummation of a Control Block Sale,
each Stockholder Group agrees to use its reasonable best efforts to (i) cause
its Stockholder Designees to take such action as may be necessary in order to
and (ii) vote all shares of Voting Stock beneficially owned by it in favor of,
an amendment to the Charter providing that upon consummation of such Control
Block Sale the shares of Series K Preferred Stock would become convertible into
shares of Series A Common Stock (on the same basis as such shares were
convertible into Series K Common Stock) and deleting all provisions of the
Charter relating to the Series K Common Stock. In addition, any Stockholder
Group holding shares of Series K Common Stock agrees to convert any such shares
of Series K Common Stock into shares of Series A Common Stock upon consummation
of such Control Block Sale. Notwithstanding the foregoing provisions of this
subsection (e), in the event that a holder of Series K Preferred Stock or Series
K Common Stock is participating in the Control Block Sale, the amendments to the
Charter referenced above and the conversion of shares of Series K Common Stock
shall not be effected to the extent that the purchaser in such Control Block
Sale has requested in writing that such amendment and/or conversion not be
effected.

          4.3  Right of First Offer.  (a)  Following the earliest to occur of
               --------------------                                          
(i) the fifth anniversary of the Execution Date, (ii the first anniversary of
the IPO, and (ii the termination of the Restricted Period as to any Cable
Parent, and provided that it shall have complied with the provisions of this
Section 4.3, a Stockholder Group will be entitled to dispose of all but not less
than all of its equity interest in the Company pursuant to (x) a Transfer of its
Company Securities to an Unaffiliated Third Party or (y) an Indirect Transfer of
such Company Securities to an Unaffiliated Third Party which Indirect Transfer
results in a Change of Control of a Stockholder (a "Restricted Indirect
                                                    -------------------
Transfer"); provided, however, that the provisions of this Section 4.3 shall not
            --------  -------                                                   
be applicable to any Transfer which is to be made in accordance with Section
4.4.  In the event that a Stockholder Group desires to Transfer its Company
Securities or enter into a transaction for such a Restricted Indirect Transfer,
the Stockholder of such Stockholder Group shall notify each other Stockholder of
its desire to enter into such a transaction (such notice, a "ROFO Notice").  In
                                                             -----------       
the case of a ROFO Notice with respect to a Restricted Indirect Transfer, such
notice shall set forth the terms and conditions upon which such Restricted
Indirect Transfer is proposed to be made.  Each ROFO Notice shall constitute an
offer by such Stockholder Group (the "ROFO Offeror") to sell all of the Company
                                      ------------                             
Securities held by such Stockholder Group (the "ROFO Shares") to the other
                                                -----------               
Stockholders (the "ROFO Stockholders").  Each ROFO Notice shall set forth the
                   -----------------                                         
type and amount of the ROFO Shares and shall specify the price per share
(determined on an as converted into Series A Common Stock basis) at which such
ROFO Offeror will Transfer such Company Securities (the "ROFO Offer Price").  In
                                                         ----------------       
the event that any ROFO 

                                     -30-
<PAGE>
 
Notice contemplates a Restricted Indirect Transfer, the ROFO Offer Price
applicable to the Company Securities to be transferred shall be the Per Share
Value. Unless otherwise agreed by the ROFO Offeror and a ROFO Stockholder
accepting such offer, the price for the ROFO Shares shall be payable in cash.

               (b) Simultaneous with the delivery of a ROFO Notice contemplating
an Indirect Transfer, the ROFO Offeror shall deliver to each other Stockholder a
notice identifying an Appraiser who has been retained by the ROFO Offeror to
determine the Per Share Value of the ROFO Shares pursuant to Article 7. Within
ten Business Days after its receipt of the Offeror's notice pursuant to the
preceding sentence, the Stockholder (other than the ROFO Offeror) that, together
with the members of its Stockholder Group, owns the greatest number of shares of
Company Securities (determined on an as converted into Series A Common Stock
basis), shall send a notice to the ROFO Offeror and the other Stockholders
identifying a second Appraiser who shall be retained by the other Stockholders
to conduct such appraisal in accordance with the Appraisal Procedures set forth
in Article 7. In the event that two Stockholders qualify to appoint the second
Appraiser because such Stockholders own an equal number of Company Securities,
such Stockholders shall agree upon and give notice of the identity of the second
Appraiser within such ten Business Day period referred to in the preceding
sentence.

               (c)  (i) If a ROFO Stockholder desires to accept the offer set
forth in a ROFO Notice as to any part of the ROFO Shares, such ROFO Stockholder
(a "ROFO Electing Stockholder") shall, within ten Business Days of receipt of
    -------------------------
such ROFO Notice or, in the event the ROFO Offer Price is to be the Per Share
Value, the tenth Business Day following the determination of the Per Share
Value, notify the ROFO Offeror of its agreement to acquire ROFO Shares and the
number of such shares it agrees to acquire, and deliver a copy of such notice to
each other Stockholder.

                    (ii) If the ROFO Electing Stockholders elect to acquire, in
the aggregate, all of the ROFO Shares, then the ROFO Electing Stockholders shall
have the right and obligation to acquire, on the applicable closing date and in
accordance with the provisions of Section 11.9, all of the ROFO Shares,
allocated among them as follows (or in such other manner as the ROFO Electing
Stockholders may agree):

                         (A) the ROFO Shares shall be allocated among the ROFO
Electing Stockholders pro rata (based on the number of Company Securities owned
by such Stockholders' respective Stockholder Groups determined on an as
converted into Series A Common Stock basis) until all of the ROFO Shares have
been allocated or any ROFO Electing Stockholder has been allocated the number of
ROFO Shares that it desires to acquire, as specified in its notice to the ROFO
Offeror, as it may have been amended pursuant to Section 4.3(c)(iii);

                         (B) if all ROFO Shares are not allocated pursuant to
paragraph (A) or any prior application of this paragraph (B), any ROFO Shares
that were not allocated pursuant to paragraph (A) or any prior application of
this paragraph (B) shall be 

                                     -31-

allocated among the ROFO Electing Stockholders (other than any ROFO Electing
Stockholder that has been allocated the number of ROFO Shares that it desires to

                                                                    ---
Offerors") shall be required, as a condition to such sale, to offer to each

               (b) The Tag Offerors shall provide prompt written notice of the
proposed Control Block Sale to each Qualified Tag Stockholder (the "Tag-Along
                                                                    ---------
Notice").  The

<PAGE>
 
Tag-Along Notice shall set forth the terms and conditions of the Control Block
Offer, including the name and address of the proposed Unaffiliated Third Party
purchaser (the "Tag-Along Buyer"), the number and type of Company Securities to 
                ---------------                                  
be sold in the Control Block Sale, the amount and type of direct and indirect
consideration to be paid per share to the Control Block Group, the form of
proposed acquisition agreement and all other material terms and conditions of
the proposed transaction. The Tag-Along Notice shall constitute an offer by the
Tag Offerors to each Qualified Tag Stockholder, which offer may be accepted by
the Qualified Tag Stockholders for a period of 20 Business Days following the
date the original Tag-Along Notice is received (the "Tag-Along Offer Period"), 
                                                     ----------------------
to include in the Control Block Sale an amount of Company Securities equal to
(x) the maximum number of Company Securities proposed to be purchased in the
Control Block Sale, multiplied by (y) a fraction, the numerator of which shall
be the number of Company Securities beneficially owned by such Qualified Tag
Stockholder's Stockholder Group and the denominator of which shall be the sum of
(i) the number of Company Securities beneficially owned by the Control Block
Group plus (ii) the number of Company Securities beneficially owned by the
Stockholder Groups of each Tag-Along Electing Stockholder (as defined below), in
each case determined prior to such Control Block Sale and determined on an as
converted into shares of Series A Common Stock basis. The Tag Offerors shall
update such notice by promptly providing each Qualified Tag Stockholder with
notice of any material changes to the information contained therein. Upon
receipt of each such updated notice (i) a Qualified Tag Stockholder who has
elected to exercise its Tag-Along Rights shall have the right to withdraw such
election by written notice delivered to each Tag Offeror within 5 Business Days
of receipt of such updated notice, provided that such Qualified Tag Stockholder,
                                   --------          
in its reasonable good faith judgment, has determined that the offer as modified
constitutes a materially adverse change from the terms and conditions of the
offer described in the original Tag-Along Notice or, if applicable, the previous
updated notice and (ii) a Qualified Tag Stockholder who has not yet elected to
exercise its Tag-Along Right may elect to so exercise by written notice
delivered to each Tag Offeror on or before the later of (x) 10 Business Days
following receipt of such updated notice and (y) the expiration of the 20
Business Day acceptance period referred to above in this clause (b).
Notwithstanding the foregoing, in the event that the Tag-Along Notice is updated
following the conclusion of such 20 Business Day acceptance period, a Qualified
Tag Stockholder which has not theretofore elected to exercise its Tag-Along
Right will be entitled to participate in such revised offer only in the event
the terms and conditions of such revised Tag-Along Notice are more favorable to
the sellers of Company Securities than the terms and conditions of the original
Tag-Along Notice or, if applicable, the previous updated notice. The foregoing
calculation with respect to the number of Company Securities which a Qualified
Tag Stockholder may include in the Control Block Sale shall be recalculated each
time another Qualified Tag Stockholder elects to participate or withdraws from
participation in the Control Block Sale following receipt of an updated notice
as provided above. Notice of such recalculated amounts shall be given to each
Stockholder by the Tag Offeror promptly following any such change in
participation by Qualified Tag Stockholders.

               (c)  (i)  If in connection with such Control Block Sale, assets,
properties or other securities, in addition to the Company Securities (or
interest therein), are to be transferred, then prior to submitting a Tag-Along
Notice pursuant to this Section 4.5, the Tag 

                                     -37-
<PAGE>
 
Offerors and the other Stockholders shall cause the total consideration
specified in the Control Block Sale to be allocated between the Company
Securities and such other assets, properties and securities in proportion with
their respective fair market values pursuant to Section 4.7.

                    (ii) Subject to Section 4.8, the Tag Offerors and the Tag-
Along Electing Stockholders agree to use their respective commercially
reasonable efforts to consummate any such Control Block Sale in a tax-free
transaction or, if not available, the most tax efficient method available.

               (d)  If any Qualified Tag Stockholder elects to exercise the Tag-
Along Right (a "Tag-Along Electing Stockholder"), such election shall be made by
                ------------------------------
such Tag-Along Electing Stockholder by written notice to that effect delivered
to each Tag Offeror prior to the expiration of the Tag-Along Offer Period. Such
notice shall (i) state that such Tag-Along Electing Stockholder is exercising
its Tag-Along Right and (ii) set forth the aggregate number of Company
Securities (specifying the number of shares of each series of Common Stock and
Preferred Stock) beneficially owned by its Stockholder Group and the number and
type of Company Securities includable in the Control Block Sale. Promptly
following the delivery of any such notice, such Tag-Along Electing Stockholder's
Stockholder Group shall agree to become a party to or otherwise become bound by
the applicable terms and conditions of the contract, agreement or instrument
pursuant to which the Control Block Group has agreed to consummate such Control
Block Sale, which terms and conditions shall be no less favorable to the Tag-
Along Electing Stockholder's Stockholder Group than the terms and conditions
applicable to the Control Block Group. The Tag-Along Electing Stockholder's
exercise of the Tag-Along Right shall be conditioned upon each member of its
Stockholder Group electing to sell Company Securities pursuant to such Tag-Along
Right becoming a party to such acquisition agreement.

               (e)  If any Qualified Tag Stockholder fails to exercise the Tag-
Along Right, or otherwise fails to comply with the requirements set forth in
Section 4.5(d), the Control Block Group (including any other Tag-Along Electing
Stockholder) shall have the right to consummate the Control Block Sale in
accordance with the terms and conditions set forth in the Tag-Along Notice (as
updated pursuant to Section 4.5(b)); provided, however, that if the Control
                                     --------  -------                     
Block Group does not consummate the Control Block Sale within 120 days following
the expiration of the Tag-Along Offer Period, the Control Block Group shall not
consummate any Control Block Sale without repeating the procedures set forth in
this Section 4.5; provided, however, that (x) any amendments, modifications or
                  --------  -------                                           
waivers of the agreement regarding such Control Block Sale occurring subsequent
to the conclusion of the Tag-Along Offer Period shall not be deemed to require
that such transaction be re-offered to such Qualified Tag Stockholders unless
the effect of such amendment, modification or waiver is to make the terms of
such Control Block Sale more favorable to the members of the Control Block Group
than the terms set forth in the last Tag-Along Notice prior to the conclusion of
the Tag-Along Offer Period and (y) any increase in the market value of the
consideration offered in any such Control Block Sale shall not constitute an
amendment, modification or waiver of any provision of such Control Block Sale
requiring further compliance with the provisions of this Section 4.5.
Notwithstanding the foregoing, if the Control Block Sale is subject to the
receipt of any regulatory approval or 

                                     -38-
<PAGE>
 
expiration of any waiting period, the time period during which such Control
Block Sale may be consummated shall be extended until the expiration of five
Business Days after all such approvals have been received or waiting periods
expired, but in no event shall such time period exceed 180 days following
expiration of such 120 day period referred to above.

               (f) Subject to the terms and conditions contained in any
agreement entered into with the Tag-Along Buyer, in the event that any members
of a Tag-Along Electing Stockholder's Stockholder Group seeking to sell Company
Securities pursuant to such Tag-Along Right fail to satisfy any condition to
consummation of such Control Block Sale such that the conditions to the Tag-
Along Buyer's obligation to purchase such shares are not timely satisfied, then
the Company Securities proposed to be sold by the members of such Tag-Along
Electing Stockholder's Stockholder Group shall be excluded from such sale, and
each other member of the Control Block Group (including each other Tag-Along
Electing Stockholder) shall be entitled to substitute Company Securities owned
by them in place of such excluded Company Securities on a pro rata basis (based
on the number of Company Securities owned by such Stockholders' respective
Stockholder Groups determined on an as converted into Series A Common Stock
basis).

           4.6 Drag-Along Right.
               ---------------- 

               (a) If any group of Stockholders composed of TCI Sub and any
other two Stockholders (which may include any Tag-Along Electing Stockholders)
(so long as such Stockholders are Eligible Stockholders and neither of such
Stockholders is a member of the same Stockholder Group as the other such
Stockholder or as TCI Sub) (a "Dragging Control Block Group") proposes to effect
                               ----------------------------

a Drag-Along Notice pursuant to Section 4.5 or 4.6, respectively, in response to
a Control Block Offer that contemplates a sale of Company Securities in
conjunction with other assets, properties or securities, the Tag Offerors or the
Dragging Control Block Group, as applicable (each of which shall be referred to
in this Section as the "Sellers") and the other Stockholders shall cause the
                        -------                                             
total consideration specified in the Control Block Offer to be allocated between
the Company Securities and such other assets, properties or securities in
proportion to their respective fair market values to be determined as follows:

               (a) The Sellers shall mutually agree upon a designee (the
"Designee") to execute such group's responsibilities pursuant to this Section 
 --------  
4.7. The Designee shall deliver to each Stockholder which is not a Seller, a
notice stating that the Sellers intend to deliver a Tag-Along Notice or Drag-
Along Notice, as applicable, to which this Section 4.7 applies and identifying
an Appraiser who has been retained by the Designee to allocate the total
consideration specified in the Control Block Offer between the Company
Securities and such other assets, properties or securities pursuant to this
Section 4.7. Within ten Business Days after its receipt of the Designee's notice
pursuant to the preceding sentence, the Qualified Tag Stockholder, in the case
of a Tag-Along Right, or the Stockholder, in the case of a Drag-Along Right
(other than any such Stockholder that is a Seller) that, together with its
Controlled Affiliates, owns the greatest

<PAGE>
 
number of shares of Company Securities (determined on an as converted into
Series A Common Stock basis), shall send a notice to the Designee and the other
Stockholders identifying a second Appraiser who shall be retained by the
Designee to determine such allocation or conduct such appraisal, as applicable,
pursuant to this Section 4.7. In the event that two Stockholders qualify to
appoint the second Appraiser because such Stockholders own an equal number of
Company Securities, such Stockholders shall agree upon and give notice of the
identity of the second Appraiser within such ten Business Day period referred to
in the preceding sentence.

               (b) The Appraisers shall submit their independent determinations
of the amount of consideration allocable to the Company Securities to be sold in
the Control Block Sale (the "Allocation") (which determination shall be made
                             ----------                                     
giving equal consideration to the amount of consideration allocable to the other
assets, properties or securities to be sold in conjunction with such Control
Block Sale) within thirty days after the date on which the second Appraiser is
retained.  If the higher determination does not exceed the lower determination
by an amount in excess of 10% of such lower determination, then the Allocation
shall be the average of the two determinations for purposes of this Section 4.7.

               (c) If the higher determination exceeds the lower determination
by an amount in excess of 10% of such lower determination, then such two
Appraisers shall promptly jointly select a third Appraiser (the "Third
                                                                 -----
Appraiser"), who shall be retained by the Designee to make an allocation or 
- ---------       
conduct an appraisal pursuant to this Section 4.7. If the first two Appraisers
are unable to agree on a Third Appraiser within thirty days, any Stockholder may
cause the American Arbitration Association of New York to appoint such Third
Appraiser. The first two Appraisers shall furnish such Third Appraiser with the
work product used by each of them in determining their respective allocations or
appraisals, as applicable. The Third Appraiser shall submit its determination of
the Allocation (which determination shall be made giving equal consideration to
the amount of consideration allocable to the other assets to be sold in
conjunction with such Control Block Sale) within thirty days after the date on
which the Third Appraiser is retained. If a Third Appraiser is retained, the
Allocation or the fair market value for purposes of Section 4.7 shall be equal
to the average of the two closest determinations; provided, however, that if the
                                                  --------  -------    
difference between the highest and middle determinations is no more than 105%
and no less than 95% of the difference between the middle and lowest
determinations, the Allocation for purposes of this Section 4.7 shall be equal
to such middle determination.

               (d) All fees and expenses of any Appraiser retained pursuant to
this Section 4.7 shall be paid by the Sellers, in proportion to their pro rata
portion of the Company Securities to be sold in the Control Block Sale
(determined on an as converted into Series A Common Stock basis).

               (e) In allocating the total consideration specified in the
Control Block Offer between the Company Securities and such other assets,
properties and securities, each Appraiser retained pursuant to this Section 4.7
shall use valuation techniques then prevailing in the relevant industry and
assume that the fair market value of the applicable asset is the price at 

                                     -41-

which the asset would change hands between a willing buyer and a willing seller,
neither being under any compulsion to buy or sell and each having reasonable
knowledge of all relevant facts.

          4.8  Allocation of Consideration.  Each item of consideration payable
               ---------------------------                                     
to the sellers of Company Securities in a transaction subject to Sections 4.5 or
4.6 shall be allocated in proportion to the number of Company Securities (as
determined on an as-converted into Series A Common Stock basis) sold by each
such seller (subject to adjustment in accordance with the second sentence of
Section 11.9(d)).

not consummated within the period set forth in Section 11.9(c) for any reason
other than a breach by the Transferring Stockholder of any of its covenants,
representations or warranties that are a condition to consummation of such
purchase, then such Proportionate Transferred Shares shall thereafter cease to

repeated at any time during the Restricted Period that the number of Exclusive
Homes Passed of a Cable Parent falls below such Cable Parent's Base Homes Passed
such that the number of Proportionate Transferred Shares of such Cable Parent's
Stockholder Group is equal to or greater than 1% of the number of Total Shares 
of such Stockholder's Stockholder Group; provided, that any such Proportionate

Receiving Stockholders as a result of this clause (c) shall be cumulated until
such time as such accumulated number of Proportionate Transferred Shares equals
or exceeds such 1% minimum threshold or the Transferring Stockholder is
otherwise required to offer shares in a Deemed Transfer.

               (d) If the Deemed Transfer occurs prior to the IPO, then the
Deemed Transfer Notice shall identify an Appraiser who has been retained by the
Transferring Stockholder to conduct an appraisal of the Company for purposes of
determining the Per Share Value of the Proportionate Transferred Shares,
pursuant to this Section 5.2(d). Within ten Business Days after its receipt of
such a Deemed Transfer Notice, the Stockholder (other than the Transferring
Stockholder) that, together with the members of its Stockholder Group, owns the
greatest number of shares of Company Securities (determined on an as converted
into Series A Common Stock basis), shall send a notice to the Transferring
Stockholder and the other Stockholders identifying a second Appraiser who shall
be retained by the Transferring Stockholder to conduct such appraisal in
accordance with the Appraisal Procedures set forth in Article 7. In the event
that two Stockholders qualify to appoint the second Appraiser because such
Stockholders own an equal number of Company Securities, such Stockholders shall
agree upon and give notice of the identity of the second Appraiser within such
ten Business Day period referred to in the preceding sentence, and if such
Stockholders cannot agree upon the identity of such second appraiser, such
appraiser shall, upon application of either such Stockholder, be selected by the
American Arbitration Association of New York.

the delivery of written notice thereof (the "KPCB Put Notice") to TCI Sub and to

the other Stockholders at any time during the KPCB Put Period to require TCI Sub

               (b) Subject to TCI Sub's right to make an IPO Election pursuant

               (c) In the event TCI Sub elects to purchase (or to cause its
designee to purchase) shares pursuant to the KPCB Put rather than making an IPO
Election, the remaining Eligible Stockholders (other than any Cable Partner

Series A Common Stock basis) in the purchase of shares pursuant to the KPCB Put
by delivery of written notice to such effect to TCI Sub and to the other
Stockholders during the twenty (20) day period following delivery of the KPCB
Put Notice; provided, however, that no exercise of such right of participation

               (e) For purposes of this Section 6.2, the obligation to purchase
Company Securities pursuant to an exercise of the KPCB Put shall be the joint
and several obligation of TCI Sub and any member of the TCI Stockholder Group

Stockholder Group shall relieve TCI Sub of its obligations pursuant to this
Section 6.2 unless specifically consented to in writing by KPCB.

           6.3 Cable Put
               ---------

               (a) In connection with the exercise of the TCI Call or the KPCB
Put (other than any exercise of the KPCB Put in connection with a KPCB Put
Triggering Event), Comcast Sub and Cox Sub shall have the right, but not the
obligation (the "Cable Put"), to require TCI Sub to purchase all, but not less
                 ---------                                                    
than all, of the Company Securities held by such Cable Partner's Stockholder
Group simultaneously with TCI Sub's purchase of Company Securities from the KPCB
Constituents pursuant to the KPCB Put or the TCI Call at the Per Share Value
thereof determined in accordance with Section 6.6.  The date of determination of
such Per Share Value shall be the date of the TCI Call Notice or the KPCB Put
Notice, as applicable.  Except as otherwise provided herein, Comcast Sub and Cox
Sub shall have the right to exercise the Cable Put in the manner, upon the same
terms and conditions, and under the circumstances described in Section 6.1 (in
the case of the TCI Call) or Section 6.2 (in the case of the KPCB Put) by giving
written notice to such effect (the "Cable Put Notice") to TCI Sub and to each
                                    ----------------                         
other Stockholder during the ten (10) day period following delivery of the KPCB
Put Notice or the TCI Call Notice, as applicable.

               (b) In the event that a Cable Partner exercises its right to
participate with TCI Sub (or its designee) in the purchase of Company Securities
pursuant to the TCI Call or the KPCB Put, such Cable Partner shall also be
obligated to purchase its proportionate interest in any Company Securities which
TCI Sub (or its designee) becomes obligated to purchase from another Cable
Partner pursuant to the Cable Put.  The number of Company Securities such Cable
Partner shall be obligated to purchase shall be determined by multiplying the
aggregate number of Company Securities which TCI Sub (or its designee) and any
participating Cable Partner are obligated to purchase pursuant to Section 6.1,
6.2 or 6.3 hereof by a fraction, the numerator of which shall be the number of
Company Securities beneficially owned by such Cable Parent and the denominator
shall be the number of Company Securities beneficially owned by TCI Sub and such
Cable Parent and their respective Stockholder Groups.  Any Cable Partner which
elects to exercise the Cable Put shall not be entitled to participate in any
purchase of Company Securities pursuant to the TCI Call or the KPCB Put.
 
               (c) Subject to TCI Sub's right to make an IPO Election pursuant

in accordance with the provisions of Section 11.9, all Company Securities
beneficially owned by such Cable Partner (or member of such Cable Partner's
Stockholder Group) as of the applicable closing date.

               (d) The Cable Put Notice shall (i) state that the applicable
Cable Partner is exercising the Cable Put and (ii set forth the aggregate number

               (e) For purposes of this Section 6.3, the obligation to purchase
Company Securities pursuant to an exercise of the Cable Put shall be the joint
and several obligation of TCI Sub and any member of the TCI Stockholder Group
acquiring Company Securities from TCI Sub, and except as provided in Section
6.7, no Transfer of Company Securities by TCI Sub to a member of the TCI
Stockholder Group shall relieve TCI Sub of its obligations pursuant to this
Section 6.3 unless specifically consented to in writing by the Cable Partner or
Cable Partners exercising the Cable Put.  In addition, an election by a Cable
Partner to participate in the purchase of Company Securities pursuant to the TCI
Call, the KPCB Put or the Cable Put shall constitute, as between such Cable
Partner and TCI Sub, such Cable Partner's agreement to acquire pursuant to the
TCI Call, KPCB Put and Cable Put, as applicable, not less than the number of
Company Securities determined pursuant to subsection (b) of this Section 6.3.

Stockholder delivered not later than 20 Business Days following the
determination of the Per Share Value, to elect (an "IPO Election") to cause the
                                                    ------------ 
Company to make an initial public offering of its Series A Common Stock in lieu
of TCI Sub's obligation to purchase Company Securities pursuant to the exercise
of such KPCB Put and, if applicable, the Cable Put or to exercise its Special
Demand Registration Right. Upon making an IPO Election, subject to Section
6.4(c) below, TCI Sub's obligation to purchase the Company Securities pursuant
to the exercise of such KPCB Put and, if applicable, the Cable Put shall be
suspended and shall terminate upon the consummation of an initial public
offering of the Company's Series A Common Stock in accordance with Section
6.4(b) below.

               (b) The Company shall as soon as reasonably practicable after the
date on which the IPO Election Notice is given, file with the Commission and use
its best efforts to cause to become effective a registration statement in
respect of the offering and sale under the Securities Act of a number of shares
of Series A Common Stock that, in the opinion of the managing underwriter of any
such offering (or if none, of any nationally recognized investment banking firm
experienced in initial public offerings of securities), is sufficient to create
a bona fide trading market for the Series A Common Stock. In addition, the
Company shall file and use its best efforts to become effective not later than
the second Business Day following the effectiveness

                                     -49-

of such registration statement under the Securities Act, a registration
statement registering the Series A Common Stock under the Exchange Act and
thereafter taking such other steps as may be reasonably necessary to cause such
shares to be listed for trading or quotation on a national securities exchange
or over the counter trading system. Each Stockholder agrees to use its
commercially reasonable efforts to cause the Company to fulfill its obligations
hereunder and shall cooperate in all respects with the preparation and filing of
such registration statement with the Commission and causing such registration
statement to become and remain effective during the time periods specified
herein.

               (c) Following TCI Sub's making of an IPO Election, (x) if such
registration of the Series A Common Stock is subsequently abandoned by the
Company before it is declared effective, (y) if a registration statement has not
been filed on or before the 90th day after the date of the IPO Election Notice,
or (z) if such registration statement has been filed, but the IPO has not been
consummated on or before the 183rd day following the date of the IPO Election
Notice, then such IPO Election shall terminate, the KPCB Put Notice and if
applicable, the Cable Put Notice shall be deemed to have been reinstated as of
such date of termination, and TCI Sub and any Cable Partner which had elected to
participate in the KPCB Put and the Cable Put shall thereafter be obligated to
purchase all of the Company Securities beneficially owned (i) by the KPCB
Constituents in accordance with the provisions of Section 6.2 and (ii) by any
Cable Partners (or member of their Stockholder Group) exercising the Cable Put
in accordance with the provisions of Section 6.3; provided, however, that
                                                  --------  -------      
notwithstanding the provisions of Section 11.9(c)(i) hereof, the minimum period
in which such sale shall be required to be consummated shall be 60 days from the
date such KPCB Put Notice and any Cable Put Notice is deemed reinstated.  In the
event a KPCB Put Notice and any Cable Put Notice is deemed reinstated pursuant
to this subsection (c), then in addition to the payment of the aggregate Per
Share Value in respect of such purchase of Company Securities, TCI Sub and any
Cable Partner electing to participate in such purchase shall pay to KPCB and to
any Cable Partners which exercise the Cable Put, interest at the Prime Rate (as
defined below) on the aggregate Per Share Value of the Company Securities to be
purchased pursuant to the KPCB Put and, if applicable, the Cable Put. Such
interest shall accrue from the date of reinstatement of the KPCB Put Notice to
and including the date immediately preceding the date of consummation of such
sale, and shall be payable upon consummation of such sale.  The term "Prime
                                                                      -----
Rate" shall mean a rate per annum equal to the commercial lending rate per annum

publicly announced from time to time by The Bank of New York as its prime rate
(such rate of interest to change as of the close of business on each date such
prime rate changes).

convertible into or exercisable or exchangeable for), as applicable, TCI, in the
case of TCI Sub, Comcast, in the case of Comcast

Sub or CCI, in the case of Cox Sub, or any Subsidiary of TCI, Comcast or CCI, as
applicable, which is a Public Company; provided that securities of the same
                                       --------   
class or series as the class or series of equity securities to be so issued, or
the class or series of securities which such security is convertible into or
exercisable or exchangeable for, are publicly traded on the Nasdaq National
Market or a national securities exchange at the time of such delivery. Such
equity securities shall be valued at the Average Market Price thereof on the
applicable closing date. The purchase price for such equity securities to be
purchased by a designee of TCI Sub shall be payable only in cash. In the event
that the equity securities to be purchased by a Stockholder pursuant to the TCI
Call, the KPCB Put or the Cable Put include options, warrants or other Rights to
acquire Company Securities which require the payment of additional consideration
in respect of the exercise thereof, the purchase price of such options,
warrants, or other Rights shall equal the Per Share Value thereof, less the
additional consideration payable in respect of the exercise of such option,
warrant or other Right.

               (b) In the event that a Stockholder shall elect to pay such
purchase price by delivering equity securities, (i) the parties shall endeavor
to consummate such transaction on a tax-free basis and (ii) such Stockholder
shall cause the issuer of such publicly traded securities to grant to KPCB, for
the benefit of the KPCB Constituents, and to the members of the Stockholder
Group of any Cable Partner exercising the Cable Put and receiving such equity
securities, customary rights with respect to the registration of such securities
under the Securities Act. Such registration rights shall provide the KPCB
Constituents and if applicable, such Cable Partner's Stockholder Group with two
demand registrations, one of which shall be exercisable such that such
registration statement would be effective no later than the tenth day following
the date of delivery of such equity securities and each of which shall be (i) at
the expense of the applicable issuer and (ii) exercisable by the KPCB
Constituents and if applicable, the members of the Stockholder Group of such
Cable Partner, with respect to the registration of not less than 20% of the
aggregate amount of equity securities of such issuer issued to KPCB and, if
applicable, the Stockholder Group of such Cable Partner, in payment of such
purchase price; provided, however, that in lieu of causing such shares to be
                --------  -------  
registered pursuant to such demand registration, the Stockholder or applicable
issuer which has granted such registration rights shall have the option to
purchase all, but not less than all, of the shares for which registration is
requested, at a price per share equal to the Average Market Price thereof (less
any estimated underwriter or broker discounts or commissions) determined as of
the date of delivery of a demand notice.

connection with TCI Call, KPCB Put and Cable Put.
- ------------------------------------------------ 

               (a) The Stockholders electing to sell Company Securities and the
Stockholders electing to purchase Company Securities pursuant to Section 6.1,
6.2 and 6.3, as applicable, shall seek in good faith to agree upon the Fair
Market Value of the Company and the related Per Share Value in accordance with
Section 7.1 promptly following the twenty-day period during which a Cable
Partner may elect to participate in such purchase.  If such parties are unable
to agree upon such Fair Market Value and Per Share Value within thirty (30) days
following the 

                                     -51-
<PAGE>

Value shall be determined as provided in clause (b).

               (b) The Stockholders who are selling Company Securities pursuant
to the TCI Call, the KPCB Put or the Cable Put (collectively, the "Selling
                                                                   -------

after the expiration of such 30-day period, either (i) jointly select and

such period, the determination of the Fair Market Value of the Company shall be
made by the Appraiser selected by the other group.  The Appraiser, or if two
Appraisers are appointed, the Appraisers shall determine the Fair Market Value
of the Company and the related Per Share Value in accordance with the appraisal
procedures set forth in Article 7.

          6.7  Termination or Amendment to the TCI Call, the KPCB Put and the

the first to occur of, (x) the date on which the IPO is consummated, (y) the
termination of this Stockholders Agreement, or (z) the consummation of a Control
Block Sale in which all Qualified Tag Stockholders were offered the opportunity
to participate as to all Company Securities owned by such Qualified Tag
Stockholders; provided, however, that in the event that such Qualified Tag
              --------  -------                                           
Stockholders were offered the opportunity to include less than all their Company
Securities in any such Control Block Sale, then the number of shares of Company
Securities which TCI Sub shall be obligated to purchase from (i) the KPCB
Constituents pursuant to an exercise of the KPCB Put upon the exercise of the
KPCB Put at any time following the consummation of such Control Block Sale or
(ii) any Cable Partner (or the members of its Stockholder Group) electing to
exercise the Cable Put pursuant to Section 6.3 hereof following an exercise of
the KPCB Put following such Control Block Sale, will in each case be reduced by
the number of Company Securities which such KPCB Constituents or Cable Partner
(and the members of its Stockholder Group), as the case may be, were offered the
opportunity to include in such Control Block Sale pursuant to Section 4.5
hereof.  The TCI Call will be deemed to have terminated upon the consummation of
any Control Block Sale.

applicable date of determination, shall mean the price at which a willing seller
would sell and a willing buyer would buy a comparable business as an ongoing
business in an arm's-length transaction (as a sale of all of the stock of the
business or, if applicable, other equity interests).  In determining the Fair
Market Value of the Company, the Stockholders, or in the event an appraisal is
required, each Appraiser, (i) shall assume for purposes of making its
determination that all of the outstanding stock or, if applicable, other equity
interests are to be sold in a single transaction and that the Company is a
Public Company and the Series A Common Stock is publicly traded and widely held,
as if a public offering of the Series A Common Stock had been successfully
consummated, (ii) shall not discount the value of the shares due to any lack of
liquidity in such shares because of any absence of a significant public market
or due to a minority ownership position in the Company represented by such
shares, (iii) shall not add any premium to the value of such shares due to a
majority or control ownership position in the Company represented by such shares
and (iv) shall not give consideration to any restrictions, encumbrances or
contractual rights relating to such shares.

          7.2  Appraisal Procedure for Fair Market Value.  If there is only one
               -----------------------------------------                       
Appraiser, the Fair Market Value of the Company shall be as determined by such
Appraiser.  If there are two Appraisers, then if the higher determination does
not exceed the lower determination by an amount in excess of 10% of such lower
determination, then the Fair Market Value shall be equal to the average of such
two determinations; however, if the higher determination exceeds the lower
determination by an amount in excess of 10% of such lower determination, then
such two Appraisers shall jointly select a third Appraiser within five days
after the date on which the later of such two Appraisal Reports (as defined
below) was delivered, and each shall furnish such third Appraiser with the work
product used by each of such Appraisers in preparing their respective Appraisal
Reports; provided, however, that in the event the first two Appraisers are
         --------  -------                                                
unable to agree on a third appraiser within thirty days, any Stockholder may
cause the American Arbitration Association of New York to appoint such third
appraiser.  Such third Appraiser shall deliver its Appraisal Report of its good
faith determination of the Fair Market Value of the Company as of the applicable
date within 20 days of such appointment, and in such case the Fair Market Value
shall be equal to the average of the two closest determinations; provided,
                                                                 -------- 
however, that if the difference between the highest and middle determinations is
- -------                                                                         
no more than 105% and no less than 95% of the difference between the middle and
lowest determinations, then the Fair Market Value of the Company shall be equal
to such middle determination.

          7.3  Determination of Per Share Value.  Following the determination of
               --------------------------------                                 
the Fair Market Value, the Stockholders, or if an appraisal is required, the
Appraisers whose determinations were used in the calculation of the Fair Market
Value, shall determine the number 

                                     -53-
<PAGE>
 
of shares of Common Stock outstanding together with any further appropriate
adjustments to the Fair Market Value resulting from such determination. The
number of shares of Common Stock outstanding shall mean a number, as determined
by such Stockholders, or if an appraisal is required, such Appraisers as of the
applicable date, equal to (without duplication) the sum of (x) the number of
shares of Series A Common Stock and Series B Common Stock outstanding, (y) the
number of shares of Series A Common Stock, Series B Common Stock and Series K
Common Stock issuable upon the conversion of the Convertible Preferred Stock and
(z) the number of shares of Series A Common Stock, Series B Common Stock and
Series K Common Stock issuable upon conversion, exercise or exchange of those
Rights the holders of which would derive an economic benefit from conversion,
exercise or exchange of such Rights which exceeds the economic benefit of not

                               PREEMPTIVE RIGHTS
                               -----------------

          8.1  Preemptive Rights.
               ----------------- 

               (a) If at any time after the Closing, the Company at any time or
from time to time makes any public or non-public offering of New Capital Stock
or any Rights to acquire New Capital Stock, each Eligible Stockholder shall
first be offered the opportunity to acquire from the Company for the same price
and on the same terms as such securities are proposed to be offered to others,
up to the amount of New Capital Stock (or Rights in respect thereof) as is
required to enable it to maintain its proportionate interest in the Company. The
amount of New Capital Stock each Eligible Stockholder shall be entitled to
purchase (or, in the case of Rights, Rights to acquire a number of shares of New
Capital Stock) shall be determined by multiplying (x) the total number of such
offered shares or, in the case of Rights, the total number or such shares
covered by Rights, by (y) a fraction, the numerator of which is the number of
shares of Company Securities (determined on an as converted into Series A Common
Stock basis) held by such Eligible Stockholder, and the denominator of which is
the number of shares of Common Stock then outstanding; provided, however, that
                                                       --------  -------   
for purposes of determining the number of shares of Common Stock outstanding,
such amount shall include, without duplication, shares of Common Stock issuable
upon the conversion of outstanding shares of Preferred Stock or other
outstanding convertible equity securities of the Company and shares of Common
Stock issuable upon the exercise of outstanding options or warrants to purchase
Common Stock (or other securities of the Company).

               (b) Notwithstanding the foregoing, no Person shall be entitled to
any preemptive rights in respect of the issuance of shares of New Capital Stock
issued to satisfy Rights theretofore issued and as to which such Person
theretofore had the opportunity to exercise preemptive rights pursuant to this
Article 8.

                                     -55-
<PAGE>
 
               (c) In the event the Company proposes to offer New Capital Stock,
it shall give each Eligible Stockholder written notice of its intention,
describing the type of New Capital Stock to be offered, and the price and other
terms upon which the Company proposes to offer the same. Each Eligible
Stockholder shall have twenty (20) days from the date of receipt of any such
notice to notify the Company in writing that it intends to exercise such
preemptive rights and as to the amount of New Capital Stock such Eligible
Stockholder desires to purchase, up to the maximum amount calculated pursuant to
subsection (a). Such notice shall constitute an agreement of such Eligible
Stockholder to purchase the amount of New Capital Stock so specified upon the
price and other terms set forth in the Company's notice to it.

               (d) If any Eligible Stockholder exercises its preemptive right
hereunder, the closing of the purchase of the New Capital Stock with respect to
which such right has been exercised shall take place within 45 calendar days
after the giving of notice of such exercise, which period of time shall be
extended for a maximum of 135 days in order to comply with applicable laws and
regulations.  Each of the Company and any Eligible Stockholder which has agreed
to purchase New Capital Stock or Rights agrees to use its commercially
reasonable efforts to secure any regulatory approvals or other consents, and to
comply with any law or regulation necessary in connection with the offer, sale
and purchase of, such New Capital Stock.

               (e) In the event any Eligible Stockholder fails to exercise its
preemptive rights provided in this Section 8.1 within said twenty (20) day
period or, if so exercised, such Eligible Stockholder is unable to consummate
such purchase within the time period specified in paragraph (d) above because of
its failure to obtain any required regulatory consent or approval, the Company
shall thereafter be entitled during the period of ninety (90) days following the
conclusion of the applicable period to sell or enter into an agreement (pursuant
to which the sale of New Capital Stock covered thereby shall be consummated, if
at all, within thirty (30) days from the date of said agreement) to sell the New
Capital Stock or Rights not elected to be purchased pursuant to this Section 8.1
or which such electing Eligible Stockholder is unable to purchase because of
such failure to obtain any such consent or approval, at a price and upon terms
no more favorable to the purchasers of such securities than were specified in
the Company's notice to the Eligible Stockholders.  Notwithstanding the
foregoing, if such sale is subject to the receipt of any regulatory approval or
expiration of any waiting period, the time period during which such sale may be
consummated shall be extended until the expiration of five Business Days after
all such approvals have been obtained or waiting periods expired, but in no
event shall such time period exceed 180 days from the date of the applicable
agreement with respect to such sale.  In the event the Company has not sold the
New Capital Stock or entered into an agreement to sell the New Capital Stock
within said ninety (90) day period (or sold and issued New Capital Stock in
accordance with the foregoing within thirty (30) days from the date of said
agreement (as such period may be extended in the manner described above for a
period not to exceed 180 days from the date of said agreement)), the Company
shall not thereafter offer, issue or sell such New Capital Stock without first
offering such securities to the Eligible Stockholders in the manner provided
above.

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

          The rights granted to the Eligible Stockholders pursuant to Section
8.1 shall terminate as to a Stockholder, upon the earlier to occur of (i) such
time as such Stockholder ceases to be an Eligible Stockholder or (ii) the
termination of this Agreement.

Group has ceased to own any Company Securities, such time as the Stockholder
Group of such Ultimate Parent ceases to own any Company Securities; provided

unless the context otherwise requires, be deemed to refer also to each
Subsidiary and Controlled Affiliate of the Company.

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

               (a)  In connection with any purchase and sale of Company
Securities between any members of one Stockholder Group, on the one hand, and
any members of another Stockholder Group, on the other, each seller of Company
Securities shall deliver to each purchaser thereof a certificate, executed by or
on behalf of such seller, in which such seller shall represent and warrant to
such purchaser as of the closing date of such transaction that:

                    (i) (A) If an entity, such seller is such an entity duly
organized, validly existing, and in good standing under the laws of the state of
its organization and (B) such seller has good title to, and the full power and
authority to sell, transfer and assign to the purchaser all of its right, title
and interest in and to, such Company Securities;

                                     -65-
<PAGE>
 
                    (ii)  there are no consents, approvals or authorizations
required under any law, rule, regulation, agreement or instrument applicable to
the seller (other than such as have previously been obtained and are in full
force and effect as of such closing date) required in order to consummate its
sale of such Company Securities to the purchaser (other than any consents,
approvals or authorizations required to be obtained by the purchaser in
connection with such purchase); and

                    (iii) immediately after the sale, transfer and assignment
thereof, such purchaser will have good title to such Company Securities free and
clear of all liens, claims or encumbrances (other than any arising pursuant to
this Agreement or under state or federal securities laws or created by the
purchaser or arising by reason of its purchase or ownership of such Company
Securities).

               (b)  In connection with any purchase and sale of Company
Securities hereunder between any members of one Stockholder Group, on the one
hand, and any members of another Stockholder Group, on the other, each purchaser
of Company Securities shall deliver to each seller thereof a certificate,
executed by or on behalf of such purchaser, in which such purchaser shall
represent and warrant to such seller as of the closing date of such transaction
that:

                    (i)  (A) If an entity, such purchaser is such an entity duly
organized, validly existing, and in good standing under the laws of the state of
its organization and (B) such purchaser has the full power and authority to
purchase, acquire and accept from the seller all of its right, title and
interest in and to such Company Securities;

                    (ii) there are no consents, approvals or authorizations
required under any law, rule, regulation, agreement or instrument applicable to
such purchaser (other than such as have previously been obtained and are in full
force and effect as of such closing date) required in order to consummate its
purchase of such Company Securities from such seller (other than any consents,
approvals or authorizations required to be obtained by such seller in connection
with such sale).

               (c)  (i)  Unless otherwise provided herein, the closing of the
purchase and sale of such Company Securities shall be held on the fifth Business
Day following satisfaction of all conditions (including any financing condition)
to such closing, but in no event later than 120 days following the date that the
total amount of Company Securities such Person is obligated to purchase is
finally determined; provided, however, that such 120-day period shall be
                    --------  -------                                   
extended for up to an additional 60 days in order to obtain any consent,
approval, or authorization or any expiration of a waiting period, which consent,
approval, authorization or expiration is a condition to the closing of such
purchase and sale.  The obligation of each Stockholder to effect such purchase
and sale shall be conditioned (satisfaction of which may not be waived by any
party thereto without the consent of the other parties thereto) upon the receipt
of any and all consents, approvals or authorizations of any governmental or
regulatory entities or other third parties, and the expiration or termination of
any waiting periods under the HSR Act applicable to the 

                                     -66-
<PAGE>
 
consummation of such purchase and sale contemplated. Each Stockholder that is a
party to such transaction shall use its commercially reasonable efforts to cause
the satisfaction of such condition. The obligation of each Stockholder
purchasing Company Securities pursuant to this Section 11.9 shall be several and
not joint and shall not be conditioned upon the consummation by any other
Stockholder purchasing Company Securities hereunder of its purchase of Company
Securities in connection with any sale of Company Securities pursuant to Section
4.3. In the event that a selling Stockholder shall become obligated to
consummate the sale of Company Securities to one or more but not all
Stockholders which have agreed to purchase Company Securities in accordance with
the terms hereof, then such selling Stockholder shall be obligated to consummate
such sale with those purchasing Stockholders who are obligated to close, and as
to any Company Securities remaining following the purchase of the Company
Securities that the purchasing Stockholders had agreed (collectively) to
purchase, each non-defaulting purchasing Stockholders shall, pursuant to written
notice to all other Stockholders delivered not later than 10 days following such
purchase default, have the option to elect to purchase such remaining shares,
which remaining shares shall be allocated among such electing Stockholders on a
pro rata basis or as they may otherwise agree, such purchase to be on the same
terms and conditions as such previous purchase; the closing of such subsequent
purchase to occur not later than 90 days following the conclusion of such 10 day
period. If any shares remain following such purchase, the selling Stockholder
shall be entitled to sell such shares to an Unaffiliated Third Party during the
period of 120 days following the conclusion of such 10 day period, provided that
the terms and conditions of such sale are no more favorable to such Unaffiliated
Third Party than the terms and conditions offered to the purchasing
Stockholders. The foregoing shall not be deemed to limit in any way any rights a
selling Stockholder may have against a defaulting Stockholder.

               (d) At the applicable closing, each purchaser of Company
Securities shall deliver to each seller thereof (i) in cash, or by certified
check or wire transfer of immediately available funds to the account specified
by such seller or (ii) in such other form of consideration as may be provided
for herein, an amount equal to the purchase price of the Company Securities to
be purchased by such purchaser from such seller. In the event that the purchase
price for Company Securities is stated in terms of a purchase price per share of
Common Stock but the Company Securities to be purchased consist of shares of
convertible Preferred Stock or options, warrants or other rights to acquire
shares of Common Stock, the purchase price with respect to each such Company
Security shall, (x) in the case of a purchase of shares of Convertible Preferred
Stock, equal the purchase price per share of Common Stock multiplied by the
number of shares of Common Stock then issuable upon the conversion of such
shares of Convertible Preferred Stock, and (y) in the case of any Right to
acquire shares of Common Stock, equal the purchase price per share of Common
Stock less the applicable exercise price of such Right. Concurrently therewith,
each seller shall deliver to each purchaser a stock certificate or certificates
representing the Company Securities to be sold by such seller to such purchaser,
duly endorsed for transfer or accompanied by duly executed stock powers, with
all requisite transfer tax stamps affixed, and such shares shall be free and
clear of all liens, claims and encumbrances (except as otherwise provided herein
and except for restrictions or resales under applicable securities laws) and all
title to, and all rights and privileges of ownership in, all such shares shall
immediately vest in such 

                                     -67-
<PAGE>
 
purchaser. At the applicable closing, each seller shall also deliver to each
purchaser, and each purchaser shall deliver to each seller, the certificates
required pursuant to Sections 11.9(a) and (b), and each seller shall deliver to
each purchaser such other certificates and documents as such purchaser may
reasonably request.

                 (e)  In connection with the allocation of Company Securities
among the Stockholders purchasing such securities in connection with (i) a right
of first offer procedure pursuant to Sections 4.3 or 4.4 or (ii) the exercise of
the TCI Call, the KPCB Put or the Cable Put and the election by Comcast Sub or
Cox Sub to participate with TCI Sub in the purchase of Company Securities
pursuant to the TCI Call, the KPCB Put or the Cable Put, any Rights included in
such Company Securities shall be allocated pro rata (both in respect of the
number of Rights and the exercise price or other price related thereto) among
each Stockholder participating in such purchase, based on the number of Company
Securities held by such participating Stockholder and the number of Company
Securities held by all participating Stockholders (determined on an as converted
into Series A Common Stock basis).

                 ---------------------                                        
agrees to negotiate in good faith with the Company and the other Stockholders

their respective Affiliates and the Company, including the exhibits thereto.
The parties acknowledge and agree that the Term Sheet is hereby terminated and

          11.13  Legends.  Any and all certificates evidencing the Company
                 -------

          Rogers and Shaw to enable such persons to then train others, provide
          scripts and other materials designed to assist Rogers, Shaw and the
          sub-distributors with Tier I Customer Support and Tier II Technical
          Support;

     (I)  provide access to @Home's subscriber management systems and the API's
          reasonably necessary to automate the exchange of data from such
          systems 

                                       6

          to Rogers, Shaw and the sub-distributors (such as IP addresses, log-in
          names, computer configuration, etc.) that are necessary for billing
          and subscriber management;`

     (J)  work with Rogers and Shaw to develop network architecture that
          minimizes inter-city data transport within Rogers' Shaw's and the sub-
          distributors' networks.

     In carrying out its obligations @Home shall treat Rogers, Shaw and the sub-
     distributors in a manner and with a priority that is equal to that afforded
     to its U.S. Cable Partners.

2.8  DUE DILIGENCE AND ACCESS:  Following the execution of this term sheet by
     ------------------------                                                
     all parties, the parties shall conduct their respective due diligence
     review of the assets, operations and the capital structure, as applicable,
     of the other.  The parties shall coordinate closely with the officers of
     the other all such activities and shall conduct any such inquiries with
     appropriate discretion and sensitivity to the relationships of the other;
     employees, customers, suppliers and distributors.  The parties agree to
     hold information obtained in confidence in accordance with the terms of the
     confidentiality agreement entered into between each of Shaw and Rogers and
     @Home and to use the information so obtained only for the purpose of
     evaluating efficacy of the transaction contemplated herein.  During this
     time the parties and their advisors and representatives shall, subject to
     confidentiality obligations to third parties, have access during normal
     business hours to such of the other's properties, books, contracts,
     documents, records and personnel related to the Service and the ability of
     any of the parties to fulfill their respective obligations under this term
     sheet and the other may reasonably request.  In the event that the
     transactions contemplated herein are not completed, the parties shall
     return all such information in written form and any copies thereof to its
     owner, and destroy all notes, working papers and schedules based on such
     confidential information.  @Home, Rogers and Shaw shall complete their due
     diligence within a reasonable time, which shall not exceed 20 business days
     following execution of this term sheet by all parties.  In the event that
     the results of the due diligence conducted by parties gives rise to the
     condition set out under paragraphs 4.1(E), 4.2(E) or 4.3(C), the applicable
     party shall be entitled to terminate the arrangements contemplated herein.

2.9  STANDARDS AND SPECIFICATIONS:  The parties will comply with mutually agreed
     ----------------------------                                               
     to Specifications and Standards that will include minimum cable plant
     performance standards, @Home Network infrastructure standards, and
     certification criteria.  In particular, Rogers and Shaw will meet certain
     minimum requirements for upstream and downstream bandwidth and @Home will
     provide for certain minimum caching rates assuming a specified subscriber
     level.

2.10 RIGHTS TO PURCHASE FROM @HOME VENDORS:  @Home will use reasonable
     -------------------------------------                            
     commercial efforts to allow Rogers, Shaw and their sub-distributors to
     purchase hardware and software for Wave@Home on an aggregate basis with
     @Home and/or the U.S. Cable Partners so that Rogers, Shaw and the sub-
     distributors can thereby enjoy advantageous terms and pricing.

2.11 @MEDIA PROGRAMMING RESPONSIBILITIES:  The parties envision that the user
     -----------------------------------                                     
     interface for Wave@Home will feature a Local Area and a National Area as
     follows:

     (A)  Rogers, Shaw or a sub-distributor, as the case may be, will program
          the Local Area and all Local Content.  Local Content shall consist
          solely of content that is intended for a specific geographic area,
          such as a city, town, municipality or metropolitan area (a "Geographic
          Area") (for example, a local restaurant guide or real estate listing
          service).  Shaw and Rogers will program the Local Area only with Local
          Content; and

     (B)  Content that is promoted in more than one Geographic Area will be
          included in the National Area.  Rogers, Shaw and @Home will jointly
          program the National Area and all National Content in accordance with
          paragraph 2.12 below.  Rogers and Shaw and the sub-distributors will
          develop relationships with Canadian content partners to provide
          National Content and @Home will utilize its relationships with U.S.
          content partners for the same purpose.

2.12 PROGRAMMING THE NATIONAL AREA:  The following principles shall apply:
     -----------------------------                                        

     (A)  The parties acknowledge the desire to present a distinctly Canadian
          service consistent with the spirit of Canadian cultural policy while
          balancing the desire to use as much of the content forming part of the
          Service as is possible.  Accordingly, Rogers and Shaw at their cost
          shall be entitled to modify, augment, or replace National Content
          programmed by @Home in order to comply with Canadian law, cultural
          policies and/or industry requirements or expectations and to ensure
          that it is relevant to the Canadian market.  Provided that Rogers and
          Shaw shall act reasonably and in good faith in order to minimize such
          changes.  The principles described in this paragraph 2.12(A) shall be
          referred to as the "Programming Principles";

     (B)  Rogers and Shaw at their cost may make editorial changes in the
          National Area and in the National Content as either of them determines
          is appropriate for the Wave@Home Service, consistent with the
          Programming Principles.  For example,  the parties will frequently
          change the lead news story, sports scores, weather conditions and
          other editorial content appearing on the news, sports and business
          guide pages so that it is oriented toward the Canadian market;

     (C)  Rogers and Shaw at their cost may supplement or replace third party
          content provided by @Home as it determines is appropriate for the
          Wave@Home Service consistent with the Programming Principles.  For
          example, Rogers and Shaw may elect to add TSN to supplement or replace
          ESPN.  Rogers and Shaw will first use commercially reasonable efforts
          to supplement such content provided by @Home by adding additional
          third party content of its choice.  If this approach is inadequate or
          is not practical, Rogers and Shaw may replace such content but will
          consult with @Home prior to doing so;

     (D)  @Home shall develop and maintain the underlying user interface and
          page templates for the Wave@Home Service (the "Programming
          Structure").  @Home

                                              ** Confidential treatment has been
                                              requested with respect to certain 
                                              information contained in this 
                                              document. Confidential portions 
                                              have been omitted from the public
                                              filing and have been filed 
                                              separately with the Securities 
                                              and Exchange Commission.
 
          will use commercially reasonable efforts to make the Programming
          Structure as flexible as possible so that Rogers and Shaw can achieve
          the Programming Principles without a need for modifications to the
          Programming Structure. A change to a Programming Structure would for
          example be replacing a shopping page which features an anchor tenant
          and four other vendors with a page modified to feature only the anchor
          tenant. If Rogers and Shaw believe that such a modification is
          necessary to achieve the Programming Principles, Rogers and Shaw will
          request that @Home implement the same, at Rogers' and Shaw's cost.
          @Home agrees that it will implement such modifications unless such
          modifications would jeopardize the technological integrity of the
          overall Programming Structure; in which case, @Home shall endeavour to
          recommend reasonable alternatives to achieve the goals or satisfy the
          concerns of Rogers and Shaw. Such requests for modifications are
          anticipated to be infrequent and normally not necessary to achieve the
          Programming Principles;

     (E)  Except as may be otherwise required by any regulatory authority,
          Rogers and Shaw will have the limited right to block the promotion of
          any programming forming part of the National Content provided by @Home
          which is competitive with any form of programming service owned or
          controlled by Rogers or Shaw (e.g.:  YTV vs. Nickelodeon) without
          reference to the Programming Principles; provided however that Rogers
          and Shaw may each block the promotion of only two such programs, in
          their respective licensed territories, at any given time; and

     (F)  @Home will make available to Rogers and Shaw the same content platform
          technologies that it makes available to its U.S. Cable Partners,
          including multi casting and replication technologies.  To the extent
          that Rogers and Shaw require content platform technologies (such as
          advertising insertion tools) that are not required by the U.S. Cable
          Partners, @Home will license such content platform technologies to
          Rogers and to Shaw on commercially reasonable terms.

2.13 @MEDIA REVENUE:  All revenue derived from the Local Area will be retained
     --------------                                                           
     by Rogers, Shaw or the sub-distributor responsible for programming the
     Local Area.  All revenue derived from the National Area will be allocated
     as follows:

     (A)  The party responsible for generating the revenue from advertising, a
          promotional link, an on-line transaction or other @Media services (the
          "Additional Revenue") shall retain [**]% of such Additional Revenue as
          a sourcing commission. The remaining Additional Revenue (i.e. [**]% of
          the Additional Revenue) will be aggregated on a quarterly basis and
          allocated in proportion to the Additional Revenue (less the sourcing
          commission) generated by each party in that quarter. However, in no
          event shall any party be entitled to less than [**]% nor more than
          [**]% of the remaining Additional Revenue; and

     (B)  Revenue from Premium Services will be allocated on a case by case
          basis in proportion to the contributions made by each party.  "Premium
          Services" are services that require Rogers' and/or Shaw's active
          participation in marketing, sales, billing and/or customer support.

                                       9
<PAGE>
 
     The parties shall reassess the above allocations following the third
     anniversary of the execution of this term sheet.

2.14 ADVERTISING PRACTICES:
     --------------------- 

     (A)  Rogers and Shaw shall schedule all advertising content forming part of
          the National Area on a non-discriminatory manner and so as to maximize
          overall advertising revenue.  Rogers and Shaw shall sell advertising
          to businesses in Canada for insertion in the Wave@Home Service and
          @Home shall sell advertising to businesses in the United States for
          insertion in the Wave@Home Service.  Rogers and Shaw on the one hand
          and @Home on the other shall share leads (for which an appropriate
          commission shall be paid) but shall not sell any such advertising to
          businesses operating in the other's territory.  All sales of
          advertising to be inserted in the Wave@Home Service shall be made in
          accordance with an advertising rate card for the Wave@Home Service;
          and

     (B)  From time to time Rogers and/or Shaw may bundle advertising on the
          Wave@Home Service with other media offerings by entities which it
          controls.  In such instance, any discount from the applicable rate
          card associated with bundling shall be allocated on an equitable
          basis.

2.15 RESEARCH & DEVELOPMENT:  @Home shall use its commercially reasonable
     ----------------------                                              
     efforts to conduct Canadian based research and development in matters
     regarding the Service and the Wave@Home Service.

2.16 BRANDING:  The Service will be marketed and distributed by Rogers and Shaw
     --------                                                                  
     under the co-brand "Wave@Home" or the brand "@Home".  Rogers' and Shaw's
     local loop (i.e. the infrastructure required to deliver the Wave@Home
     Service to the subscriber from the RDC's) will be referred to as the
     "Wave".  Rogers and Shaw and the sub-distributor may use a tag line to
     identify Wave@Home as a product of Rogers, Shaw or the sub-distributor.
     Rogers and Shaw shall grant to @Home a non-exclusive license to use the
     appropriate trade marks owned by either of them to market and promote the
     Wave@Home Service.  Provided that nothing set out in this paragraph shall
     give Rogers or Shaw any ownership rights to the trade mark "@Home".

2.17 FEES:  The following fees shall apply to the Licenses:
     ----                                                  

     (A)  Wave@Home will be offered to Rogers' and Shaw's and their sub-
          distributors' subscribers at basic subscription rates (which may be
          based on a month-to-month or longer term subscriptions), cable modem
          rates, and installation rates determined by Rogers, Shaw and their
          sub-distributors in their sole discretion.  The basic subscription
          rate shall include local loop transport fees and Internet Service
          provider fees and may be allocated between local loop transport fees
          and Internet Service provider fees in any manner that Rogers and Shaw
          deem appropriate subject to any applicable legal requirements relating
          to the pricing of these services; and

                                              requested with respect to certain 
                                              information contained in this 
                                              document. Confidential portions 
                                              have been omitted from the public
                                              filing and have been filed 
                                              separately with the Securities 
                                              and Exchange Commission.
 
     (B)  In consideration of the License granted hereunder and the performance
          of @Home's obligations, Rogers and Shaw will pay @Home [**]% (the "Fee
          Percentage") of the Wave@Home basic subscription rate revenue,
          including any portion allocated to local loop transport (the
          "Wave@Home Services Revenue") billed by Rogers, Shaw and its sub-
          distributors.  The parties acknowledge that the Wave@Home Service
          Revenue is presently set out in the High Speed Internet Access Tariff
          filed by each of Rogers and Shaw with the CRTC.  The tariffs do not
          include installation charges, any sales, use, gross receipts, excise,
          franchise or other local, provincial and federal taxes, fees or
          charges, however designated (excluding taxes on the other party's
          income) imposed on or based upon the provision or use of Wave@Home
          Services, management fees described in paragraph 2.3(B), @Media
          revenue described in paragraph 2.13, or any incremental fees collected
          for additional content or programming or the fees charged for the sale
          or rental of cable modems, all of which amounts shall in all cases be
          excluded from the calculation of the Wave@Home Service Revenue.
          Rogers and Shaw will not and the sub-distribution agreements will
          provide that the sub-distributors shall not artificially allocate
          costs between the Wave@Home Service Revenue and the other fee
          categories excluded above in order to lower Rogers' and Shaw's
          payments to @Home.  All payments under this term sheet will be net 30
          days from the calendar month end; and

     (C)  Rogers, Shaw or any sub-distributor will be entitled to include the
          Wave@Home Service in a bundled offer with other products or services
          offered by such party or other ("Bundled Offer") and sold to
          subscribers at a single discounted price.  If Rogers or Shaw wish to
          include that Wave@Home in a Bundled Offer such party may request that
          @Home agree that the Wave@Home Service Revenue for the purpose of
          section 2.17(B) will be equal to the discounted price for the
          Wave@Home Service included in the Bundled Offer.  The discounted price
          will be determined by dividing (i) the price for the Bundled Offer by
          (ii) the sum of the standard price for each service included in the
          Bundled Offer and multiplying the resulting percentage by the un-
          discounted Wave@Home Service Revenue.  @Home will act reasonably in
          giving its consent and will take into consideration the likely
          benefits of the Wave@Home Service being included in the Bundled Offer.
          Failing such consent if Rogers or Shaw proceeds with the Bundled
          Offer, the Wave@Home Service Revenue will be calculated without
          reference to any discount.

     All fees or other payments by one party to the other as contemplated herein
     shall be reduced by all statutory withholding obligations imposed on such
     party including any taxes required to be withheld pursuant to Canadian or
     U.S. laws.

2.18 PERFORMANCE BASED INCREASE IN @HOME SERVICE FEES:  The fees payable to
     ------------------------------------------------                      
     @Home shall be increased in the manner set out in Schedule "E" attached
     hereto.

2.19 TERM:  The initial terms of the Licenses and this term sheet (or the
     ----                                                                
     definitive distribution agreement if executed and as such supersedes the
     term sheet) will be six years.  Rogers and Shaw shall each have the right
     to renew this agreement for two additional six year 

                                       11
<PAGE>
 
     terms subject to reaching agreement with @Home with respect to the overall
     economics of the contractual arrangements for any such renewal period. At
     the end of the fifth and eleventh year the parties will review the overall
     economics of the contractual arrangements and negotiate in good faith any
     amendments sought to the contractual arrangements by any of the parties for
     any renewal term.

2.20 TRANSITION PERIOD:  If the contractual arrangements set out herein
     -----------------                                                 
     terminate as a result of the:

     (A)  failure of the parties to reach agreement on the economic terms to
          take effect on renewal as contemplated in paragraph 2.19 above, there
          will be a twelve month transitional period following such termination
          or such shorter period of time as shall be agreed upon by the parties;
          and

     (B)  the breach of one of the parties, and subject to the requirements of
          Section 2.1(i), (ii) and (iii), there will be a transition period of
          such duration as shall be mutually agreed upon, not to exceed nine
          months provided however that the party in breach shall use all its
          reasonable commercial efforts to remedy the breach and shall continue
          to fulfill its other contractual obligations.

     During the transitional periods described above Rogers and Shaw may, but
     need not, continue to use the "Wave@Home" co-brand or "@Home" brand, as the
     case may be.  During the transition period the parties will otherwise be
     bound by their obligations set out in this term sheet including the payment
     of fees and the exclusivity obligation of the parties (subject to the right
     of the parties to prepare to contract with an alternative provider).  In
     addition during the transition period, the parties will co-operate and work
     together in good faith to effect a smooth and orderly transition from the
     facilities, networks, technology and services provided by each of the
     parties hereunder to the separate facilities, networks, technology and
     services required by each of the parties after the end of the transition
     period.

3.0  ADDITIONAL VENTURES

3.1  @HOME COMMERCIAL SERVICES:  @Home, Rogers and Shaw will negotiate in good
     -------------------------                                                
     faith until December 31, 1997 with a view to signing a distribution
     agreement granting Rogers and Shaw an exclusive license in Canada covering
     @Home's commercial services (such as @Work Remote for telecommuters and
     @Work Internet access service).  Nothing in this paragraph is intended to
     prohibit either party from entering into any arrangement with any other
     party to provide such commercial services in Canada.  However, in the event
     that @Home offers a commercial product with another Internet Service
     provider, @Home shall not use "@Home" as the product name for such service
     and shall use its good faith efforts to disassociate the @Home name or
     trade mark with such service.  It being agreed that regardless of the
     success of the negotiations regarding these @Home commercial services,
     nothing herein shall limit the ability of Rogers and Shaw to distribute,

                                  ----------

                               SUMMARY OF TERMS
                               ----------------

           WARRANTS TO PURCHASE SERIES C CONVERTIBLE PREFERRED STOCK

Issuer:  At Home Corporation, a Delaware corporation (the "Company").

Assumptions:        The following terms assume (a) the purchase by each of
                    Rogers and Shaw of US $15,000,000 of the Company's Series C
                    Preferred Stock ("Series C Preferred Stock") at $200 per
                    share in connection with the issuance of the Warrants
                    described below and (b) that each share of Series C
                    Preferred Stock shall, as presently constituted, be
                    convertible into 20 shares of Series A Common Stock of the
                    Company ("Series A Common Stock") at an effective price of
                    $10 per share of Series A Common Stock. If Rogers or Shaw
                    purchases less than $15,000,000 of Series C Preferred Stock
                    each, the number of shares subject to the Warrants will be
                    reduced as may be agreed by the parties.

Exercise Price:     The Exercise Price of each Warrant shall equal the original
                    issue price of the Series C Preferred Stock ($200 per share
                    of Series C Preferred Stock, which is equivalent to $10 per
                    share of Series A Common Stock), and shall be appropriately
                    adjusted to maintain a constant total exercise price in the
                    event such Warrant becomes exercisable for Series A Common
                    Stock or some other series or class of the Company's capital
                    stock.

Purchase Price:     The purchase price of each Warrant shall be 0.01% of the
                    aggregate Exercise Price of such Warrant. Such purchase
                    price shall be paid in cash at the Closing.

Warrants:           Warrant 1:  Rogers and Shaw will each be granted such 
                    ---------            
                    number of warrants so as to entitle each of Rogers and Shaw
                    to purchase shares of Series C Preferred Stock convertible
                    into 650,000 shares of Series A Common Stock ("Warrant 1").

                    Warrant 2:  Rogers and Shaw will each be granted such number
                    ---------                                                   
                    of warrants so as to entitle each of Rogers and Shaw to
                    purchase shares of Series C Preferred Stock convertible into
                    80,000 shares of Series A Common Stock ("Warrant 2").

                    Warrant 3:  Rogers and Shaw will each be granted such number
                    ---------                                                   
                    of warrants so as to entitle each of Rogers and Shaw to
                    purchase shares of Series C Preferred Stock convertible into
                    270,000 shares of Series A Common Stock ("Warrant 3").

                  WAVE@HOME CUSTOMER SERVICE TIER DESCRIPTIONS

Tier I Customer Support
- -----------------------

Tier I customer service is the "front line" of the Wave@Home Service.  All
customer inquiries initially will be directed to Tier I customer service
representatives ("CSRs").

The tasks listed below are typically provided by Tier I CSRs.  However, if the
MSO delegates Tier I service responsibility to @Home, MSO and @Home will review
these tasks to determine whether MSO can perform some of these functions without
the assistance of @Home technical service representatives ("TSRs").

     Providing information about the Wave@Home Service.

     Determining service eligibility (i.e. correct geographic location and
     computer configuration) of potential subscribers.

     Providing support for Data and RF technicians during the installation
     process at the subscriber's home.

     Processing all start, stop and change requests for the Wave@Home Service.

     Establishing IP addresses, logins, email, passwords, and related customer
     identifications and other records for use by @Home and MSO as permitted by
     the Agreement.

     Addressing billing and pricing questions.

                                                     -----                 

          .    All desktop hardware and software support will be handled by Tier
               I CSRs.
          .    Such support will be provided via email, phone and on-site
               visits.
          .    By way of example, all known "bugs", operating system
               configuration issues, and @Home software installation and upgrade
               questions would be handled by Tier I CSRs.
          .    MSO and @Home anticipate that in excess of 80% of all customer
               calls relating to desktop problems will be resolved by Tier I
               CSRs without the assistance of Tier II TSRs.

     Maintaining trouble ticket status reports and cataloging customer problems
     and problem resolutions.

Tier II Technical Support
- -------------------------

Tier II customer service is the advanced diagnostic and problem resolution layer
of the Wave@Home Service and includes the tasks set forth below.  Tier II TSRs
are not responsible for answering initial customer inquiries but may from time-
to-time have customer calls transferred to them.  The tasks listed below are
typically provided by Tier II TSRs:

     approximately 20% of the customer calls that require additional problem
     diagnosis and resolution.

     Developing and maintaining an on-line information system for Tier I CSRs.

Tier III Network Support
- ------------------------

Tier III customer service will address Tier II escalations from TSRs relating to
network problems and perform ongoing network monitoring and maintenance.  Tier
III technicians will not interact with subscribers directly.

3.  Provided that, in determining if Rogers and/or Shaw, as applicable, has
reached the number of Homes Passed and the Penetration Percentages set out in
Table 3, the following shall apply:

(a)  that number of Homes Passed and Penetration Percentages reached by Rogers
     in excess of those numbers and percentages set out in Table 1, and reached
     by Shaw in excess of those numbers and percentages set out in Table 2,
     shall be attributed to the numbers of Homes Passed and Penetration
     Percentages for the purpose of determining compliance with Table 3; and
(b)  that number of Homes Passed and Penetration Percentages reached by the sub-
     distributors or others in Canada (whether or not their relationship with
     @Home is direct or indirect) shall be attributed to the number of Homes
     Passed and Penetration Percentages set out in Table 3 as if 60% of such
     Homes Passed and 60% of such Penetration Percentages reached by such
     persons were reached by Rogers and as if 40% of such Homes Passed and 40%
     of such Penetration Percentages reached by such persons were reached by
     Shaw; and
(c)  if after making the calculations set out in sub-paragraph 3 (a) and (b)
     above, it is determined that either Rogers or Shaw has satisfied the
     performance obligations set out in, the case of Rogers in Tables 1 and 3,
     and in the case of Shaw in Tables 2 and 3, but the other has not, that
     number of Homes Passed and the Penetration Percentage in excess of the
     targets imposed shall be attributed to such of the parties who has failed
     to meet the required number of Homes Passed and Penetration Percentages;
     and
(d)  further, homes which are fully 2way capable or telco return capable will be
     included as if such homes were Homes Passed, and any subscriber to the
     WAVE@Home Service, whether on 2way cable or telco return, will be counted
     as a subscriber to the WAVE@Home Service, for the purpose of calculating
     the Penetration Percentages set out in Table 3.

4.  The number of Homes Passed above will be adjusted for any system divestiture
by Rogers or Shaw over the course of the term of the term sheet or any renewal
thereof. The % Rebuilt specified in Tables 1 and 2 above will remain constant in
the event of any system divestiture.  In the event of a substantial divestiture,
Rogers and Shaw will use all reasonable efforts to appoint such purchaser as a
subdistributor of the WAVE@Home Service in the purchased systems.

                           INDEMNIFICATION AGREEMENT

     This Agreement, made and entered into this ___ day of ________________,
1997 ("Agreement"), by and between At Home Corporation, a Delaware corporation
("Company"), and _____________________________ ("Indemnitee"):

     WHEREAS, highly competent persons have become more reluctant to serve
privately- and publicly-held corporations as directors or in other capacities
unless they are provided with adequate protection through insurance or adequate
indemnification against inordinate risks of claims and actions against them
arising out of their service to and activities on behalf of the corporation; and

     WHEREAS, directors, officers, and other persons in service to corporations
or business enterprises are being increasingly subjected to expensive and time-
consuming litigation relating to, among other things, matters that traditionally
would have been brought only against the Company or business enterprise itself;
and

     WHEREAS, the uncertainties relating to such insurance and to
indemnification have increased the difficulty of attracting and retaining such
persons; and

     WHEREAS, the Board of Directors of the Company (the "Board") has determined
that the increased difficulty in attracting and retaining such persons is
detrimental to the best interests of the Company's stockholders and that the
Company should act to assure such persons that there will be increased certainty
of such protection in the future; and

     WHEREAS, it is reasonable, prudent and necessary for the Company
contractually to obligate itself to indemnify such persons to the fullest extent
permitted by applicable law so that they will service or continue to serve the
Company free from undue concern that they will not be so indemnified; and

     WHEREAS, this Agreement is a supplement to and in furtherance of the
Certificate of Incorporation and the Bylaws of the Company and any resolutions
adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to
diminish or abrogate any rights of Indemnitee thereunder; and

     WHEREAS, the Certificate of Incorporation, the Bylaws and the Delaware
director indemnification statute each is nonexclusive, and therefore each
contemplates that contracts may be entered into with respect to indemnification
of directors, officers and employees; and

     WHEREAS, it is reasonable, prudent and necessary for the Company
contractually to obligate itself to indemnify, and to advance expenses on behalf
of, such persons to the fullest extent permitted by applicable law so that they
will serve or continue to serve the Company free from undue concern that they
will not be so indemnified; and
<PAGE>
 
     WHEREAS, Indemnitee is willing to serve, continue to serve and to take on
additional service for or on behalf of the Company on the condition that he be
so indemnified;

     NOW, THEREFORE, in consideration of the premises and the covenants
contained herein, the Company and Indemnitee do hereby covenant and agree as
follows:

     Section 1.  Services by Indemnitee.  Indemnitee agrees to serve and/or
                 ----------------------
continue to serve as a director, officer, employee and/or agent of the Company
and, and at the request of the Company, as a director, officer, employee, agent
and/or fiduciary of another corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise.  Indemnitee may at any time and for
any reason resign from such position (subject to any other contractual
obligation or any obligation imposed by operation of law), in which event the
Company shall have no obligation under this Agreement to continue Indemnitee in
such position.  This Agreement shall not be deemed an employment contract
between the Company (or any of its subsidiaries) and Indemnitee.  Indemnitee
specifically acknowledges that Indemnitee's employment with the Company (or any
of its subsidiaries), if any, is at will, and that Indemnitee may be discharged
at any time for any reason, with or without cause, except as may be otherwise
provided in any written employment contract between Indemnitee and the Company
(or any of its subsidiaries), other applicable formal severance policies duly
adopted by the Board, or, with respect to service as a director of the Company,
by the Company's Certificate of Incorporation, Bylaws, and the General
Corporation Law of the State of Delaware.  The foregoing notwithstanding, this
Agreement shall continue in force after Indemnitee has ceased to serve as an
officer, director, employee and/or agent of the Company or as a director,
officer, employee, agent and/or fiduciary of another corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise.

     Section 2.  Indemnification - General.  The Company shall indemnify, and
                 -------------------------
advance Expenses (as hereinafter defined) to, Indemnitee (a) as provided in this
Agreement and (b) (subject to the provisions of this Agreement) to the fullest
extent permitted by applicable law in effect on the date hereof and as amended
from time to time.  The rights of Indemnitee provided under the preceding
sentence shall include, but shall not be limited to, the rights set forth in the
other Sections of this Agreement.

     Section 3.  Proceedings Other Than Proceedings by or in the Right of the
                 ------------------------------------------------------------
Company.  Indemnitee shall be entitled to the rights of indemnification provided
- -------
in this Section 3 if, by reason of his Corporate Status (as hereinafter
defined), he is, or is threatened to be made, a party to or a participant in any
threatened, pending, or completed Proceeding (as hereinafter defined), other
than a Proceeding by or in the right of the Company.  Pursuant to this Section
3, Indemnitee shall be indemnified against all Expenses, judgments, penalties,
fines and amounts paid in settlement (including all interest, assessments and
other charges paid or payable in connection with or in respect of such Expenses,
judgments, penalties, fines and amounts paid in settlement) actually and
reasonably incurred by him or on his behalf in connection with such Proceeding
or any claim, issue or matter therein, if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of the
Company and, with respect to any criminal Proceeding, had no reasonable cause to
believe his conduct was unlawful.

                                      -2-
<PAGE>
 
     Section 4.  Proceedings by or in the Right of the Company.  Indemnitee
                 ---------------------------------------------
shall be entitled to the rights of indemnification provided in this Section 4
if, by reason of his Corporate Status, he is, or is threatened to be made, a
party to or a participant in any threatened, pending or completed Proceeding
brought by or in the right of the Company to procure a judgment in its favor.
Pursuant to this Section, Indemnitee shall be indemnified against all Expenses
(including all interest, assessments and other charges paid or payable in
connection with or in respect of such Expenses) actually and reasonably incurred
by him or on his behalf in connection with such Proceeding if he acted in good
faith and in a manner he reasonably believed to be in or not opposed to the best
interests of the Company; provided, however, that, if applicable law so
provides, no indemnification against such Expenses shall be made in respect of
any claim, issue or matter in such Proceeding as to which Indemnitee shall have
been adjudged to be liable to the Company unless and to the extent that the
Court of Chancery of the State of Delaware, or the court in which such
Proceeding shall have been brought or is pending, shall determine that such
indemnification may be made.

     Section 5.  Partial Indemnification.  Notwithstanding any other provision
                 -----------------------
of this Agreement, to the extent that Indemnitee is, by reason of his Corporate
Status, a party to (or a participant in) and is successful, on the merits or
otherwise, in defense of any Proceeding, he shall be indemnified against all
Expenses actually and reasonably incurred by him or on his behalf in connection
therewith.  If Indemnitee is not wholly successful in defense of such Proceeding
but is successful, on the merits or otherwise, as to one or more but less than
all claims, issues or matters in such Proceeding, the Company shall indemnify
Indemnitee against all Expenses actually and reasonably incurred by him or on
his behalf in connection with each successfully resolved claim, issue or matter.
For purposes of this Section and without limitation, the termination of any
claim, issue or matter in such a Proceeding by dismissal, with or without
prejudice, shall be deemed to be a successful result as to such claim, issue or
matter.  If Indemnitee is entitled under any provision of this agreement to
indemnification by the Company for some or a portion of the Expenses, judgments,
penalties, fines and amounts paid in settlement (including all interest,
assessments and other charges paid or payable in connection with or in respect
of such Expenses, judgments, penalties, fines and amounts paid in settlement)
actually and reasonably incurred by him or on his behalf in connection with such
Proceeding or any claim, issue or matter therein, but not, however, for the
total amount thereof, the Company shall nevertheless indemnify Indemnitee for
the portion to which Indemnitee is entitled.

     Section 6.  Indemnification for Additional Expenses.
                 ----------------------------------------

     (a) The Company shall indemnify Indemnitee against any and all Expenses
and, if requested by Indemnitee, shall (within twenty (20) business days of such
request) advance such Expenses to Indemnitee, which are incurred by Indemnitee
in connection with any action brought by Indemnitee for (i) indemnification or
advance payment of Expenses by the Company under this Agreement or any other
agreement or bylaw of the Company now or hereafter in effect; or (ii) recovery
under any directors' and officers' liability insurance policies maintained by
the Company, regardless of whether Indemnitee ultimately is determined to be
entitled to such indemnification, advance expense payment or insurance recovery,
as the case may be.

                                      -3-
<PAGE>
 
     (b) Notwithstanding any other provision of this Agreement, to the extent
that Indemnitee is, by reason of his Corporate Status, a witness in any
Proceeding to which Indemnitee is not a party, he shall be indemnified against
all Expenses actually and reasonably incurred by him or on his behalf in
connection therewith.

     Section 7.  Advancement of Expenses.  The Company shall advance all
                 -----------------------
reasonable Expenses incurred by or on behalf of Indemnitee in connection with
any Proceeding within twenty (20) days after the receipt by the Company of a
statement or statements from Indemnitee requesting such advance or advances from
time to time, whether prior to or after final disposition of such Proceeding.
Such statement or statements shall reasonably evidence the Expenses incurred by
Indemnitee and shall include or be preceded or accompanied by an undertaking by
or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately
be determined that Indemnitee is not entitled to be indemnified against such
Expenses.  Notwithstanding the foregoing, the obligation of the Company to
advance Expenses pursuant to this Section 7 shall be subject to the condition
that, if, when and to the extent that the Company determines that Indemnitee
would not be permitted to be indemnified under applicable law, the Company shall
be entitled to be reimbursed, within thirty (30) days of such determination, by
Indemnitee (who hereby agrees to reimburse the Company) for all such amounts
theretofore paid; provided, however, that if Indemnitee has commenced or
                  --------  -------
thereafter commences legal proceedings in a court of competent jurisdiction to
secure a determination that Indemnitee should be indemnified under applicable
law, any determination made by the Company that Indemnitee would not be
permitted to be indemnified under applicable law shall not be binding and
Indemnitee shall not be required to reimburse the Company for any advance of
Expenses until a final judicial determination is made with respect thereto (as
to which all rights of appeal therefrom have been exhausted or lapsed).

     Section 8.  Procedure for Determination of Entitlement to Indemnification.
                 --------------------------------------------------------------

     (a) To obtain indemnification under this Agreement, Indemnitee shall submit
to the Company a written request, including therein or therewith such
documentation and information as is reasonably available to Indemnitee and is
reasonably necessary to determine whether and to what extent Indemnitee is
entitled to indemnification.  The Secretary of the Company shall, promptly upon
receipt of such a request for indemnification, advise the Board in writing that
Indemnitee has requested indemnification.

     (b) Upon written request by Indemnitee for indemnification pursuant to the
first sentence of Section 8(a) hereof, a determination, if required by
applicable law, with respect to Indemnitee's entitlement thereto shall be made
in the specific case at the election of Indemnitee, by any of the following
procedures:  (i) by a majority vote of the Disinterested Directors (as
hereinafter defined), even though less than a quorum of the Board, or (ii)  by
Independent Counsel in a written opinion to the Board, a copy of which shall be
delivered to Indemnitee or (iii) by the stockholders of the Company; and, if it
is so determined that Indemnitee is entitled to indemnification, payment to
Indemnitee shall be made within seven (7) business days after such
determination.  Indemnitee shall cooperate with the person, persons or entity
making such determination with respect to Indemnitee's entitlement to
indemnification, including providing to such person, persons or entity upon
reasonable advance request any 

                                      -4-
<PAGE>
 
documentation or information which is not privileged or otherwise protected from
disclosure and which is reasonably available to Indemnitee and reasonably
necessary to such determination. Any costs or expenses (including reasonable
attorneys' fees and disbursements) incurred by Indemnitee in so cooperating with
the person, persons or entity making such determination shall be borne by the
Company (irrespective of the determination as to Indemnitee's entitlement to
indemnification) and the Company hereby indemnifies and agrees to hold
Indemnitee harmless therefrom.

     (c) In the event the determination of entitlement to indemnification is to
be made by Independent Counsel pursuant to Section 8(b) hereof, the Independent
Counsel shall be selected as provided in this Section 8(c).  The Independent
Counsel shall be selected by Indemnitee (unless Indemnitee shall request that
such selection be made by the Board of Directors, in which event the Board shall
select such counsel and give written notice to Indemnitee of the identity of
such Independent Counsel), and Indemnitee shall give written notice to the
Company advising it of the identity of the Independent Counsel so selected.  In
either event, Indemnitee or the Company, as the case may be, may, within ten
(10) days after such written notice of selection shall have been given, deliver
to the Company or to Indemnitee, as the case may be, a written objection to such
selection; provided, however, that such objection may be asserted only on the
           --------  -------
ground that the Independent Counsel so selected does not meet the requirements
of "Independent Counsel" as defined in Section 17 of this Agreement, and the
objection shall set forth with particularity the factual basis of such
assertion.  If such written objection is so made and substantiated, the
Independent Counsel so selected may not serve as Independent Counsel unless and
until such objection is withdrawn or a court has determined that such objection
is without merit.  If, within twenty (20) days after submission by Indemnitee of
a written request for indemnification pursuant to Section 8(a) hereof, no
Independent Counsel shall have been selected and not objected to, either the
Company or Indemnitee may petition the Court of Chancery of the State of
Delaware for resolution of any objection which shall have been made by the
Company or Indemnitee to the other's selection of Independent Counsel and/or for
the appointment as Independent Counsel of a person selected by the Court or by
such other person as the Court shall designate, and the person with respect to
whom all objections are so resolved or the person so appointed shall act as
Independent Counsel under Section 8(b) hereof.  The Company shall pay any and
all reasonable fees and expenses of Independent Counsel incurred by such
Independent Counsel in connection with acting pursuant to Section 8(b) hereof,
and the Company shall pay all reasonable fees and expenses incident to the
procedures of this Section 8(c), regardless of the manner in which such
Independent Counsel was selected or appointed.  Upon the due commencement of any
judicial proceeding or arbitration pursuant to Section 10(a)(iii) of this
Agreement, Independent Counsel shall be discharged and relieved of any further
responsibility in such capacity (subject to the applicable standards of
professional conduct then prevailing).

     (d) The Company shall not be required to obtain the consent of Indemnitee
to the settlement of any Proceeding which the Company has undertaken to defend
if the Company assumes full and sole responsibility for such settlement and such
settlement grants Indemnitee a complete and unqualified release in respect of
the potential liability.  The Company shall not be 

                                      -5-
<PAGE>
 
liable for any amount paid by Indemnitee in settlement of any Proceeding that is
not defended by the Company, unless the Company has consented in writing to such
settlement, which consent shall not be unreasonably withheld.

     (e) In the event the Company shall be obligated to advance the expenses for
any Proceeding against Indemnitee, the Company, if appropriate, shall be
entitled to assume the defense of such proceeding, upon the delivery to
Indemnitee of written notice of its election to do so.  After delivery of such
notice and the retention of such counsel by the Company, the Company will not be
liable to Indemnitee under this Agreement for any fees of counsel subsequently
incurred by Indemnitee with respect to the same Proceeding, provided that (a)
Indemnitee shall have the right to employ his own counsel in any such proceeding
at Indemnitee's expense; (b) Indemnitee shall have the right to employ his own
counsel in connection with any such Proceeding, at the expense of the Company,
if such counsel serves in a review, observer, advice and counseling capacity and
does not otherwise materially control or participate in the defense of such
Proceeding; and (c) if (i) the employment of counsel by Indemnitee has been
previously authorized by the Company, (ii) Indemnitee shall have reasonably
concluded that there may be a conflict of interest between the Company and
Indemnitee in the conduct of any such defense or (iii) the Company shall not, in
fact, have employed counsel to assume the defense of such Proceeding, then the
reasonable fees and expenses of Indemnitee's counsel shall be at the expense of
the Company.

     Section 9.  Presumptions and Effect of Certain Proceedings.
                 -----------------------------------------------

     (a) In making a determination with respect to entitlement to
indemnification or the advancement of expenses hereunder, the person or persons
or entity making such determination shall presume that Indemnitee is entitled to
indemnification or advancement of expenses under this Agreement if Indemnitee
has submitted a request for indemnification or the advancement of expenses in
accordance with Section 8(a) of this Agreement, and the Company shall have the
burden of proof to overcome that presumption in connection with the making by
any person, persons or entity of any determination contrary to that presumption.
Neither the failure of the Company (including the Board or independent legal
counsel) to have made a determination prior to the commencement of any action
pursuant to this Agreement that indemnification is proper in the circumstances
because Indemnitee has met the applicable standard of conduct, nor an actual
determination by the Company (including the Board or independent legal counsel)
that Indemnitee has not met such applicable standard of conduct, shall be a
defense to the action or create a presumption that Indemnitee has not met the
applicable standard of conduct.

     (b) If the person, persons or entity empowered or selected under Section 8
of this Agreement to determine whether Indemnitee is entitled to indemnification
shall not have made a determination within sixty (60) days after receipt by the
Company of the request therefor, the requisite determination of entitlement to
indemnification shall be deemed to have been made and Indemnitee shall be
entitled to such indemnification, absent (i) a misstatement by Indemnitee of a
material fact, or an omission of a material fact necessary to make Indemnitee's
statement not materially misleading, in connection with the request for
indemnification, or (ii) a prohibition of 

                                      -6-
<PAGE>
 
such indemnification under applicable law; provided, however, that such 60-day
                                           --------  -------
period may be extended for a reasonable time, not to exceed an additional thirty
(30) days, if the person, persons or entity making the determination with
respect to entitlement to indemnification in good faith requires such additional
time for the obtaining or evaluating of documentation and/or information
relating thereto; and provided, further, that the foregoing provisions of this
                      --------  -------
Section 9(b) shall not apply (i) if the determination of entitlement to
indemnification is to be made by the stockholders pursuant to Section 8(b) of
this Agreement and if (A) within fifteen (15) days after receipt by the Company
of the request for such determination the Board of Directors has resolved to
submit such determination to the stockholders for their consideration at an
annual meeting thereof to be held within seventy-five (75) days after such
receipt and such determination is made thereat, or (B) a special meeting of
stockholders is called within fifteen (15) days after such receipt for the
purpose of making such determination, such meeting is held for such purpose
within sixty (60) days after having been so called and such determination is
made thereat, or (C) a written consent of stockholders is solicited within
fifteen (15) days after such receipt for the purpose of making such
determination, and such consent is obtained within sixty (60) days after such
solicitation, or (ii) if the determination of entitlement to indemnification is
to be made by Independent Counsel pursuant to Section 8(b) of this Agreement.

     (c) The termination of any Proceeding or of any claim, issue or matter
therein, by judgment, order, settlement or conviction, or upon a plea of nolo
                                                                         ----
contendere or its equivalent, shall not (except as otherwise expressly provided
- ----------
in this Agreement) of itself adversely affect the right of Indemnitee to
indemnification or create a presumption that Indemnitee did not act in good
faith and in a manner which he reasonably believed to be in or not opposed to
the best interests of the Company or, with respect to any criminal Proceeding,
that Indemnitee had reasonable cause to believe that his conduct was unlawful.

     (d) For purposes of any determination of "good faith," Indemnitee shall be
deemed to have acted in "good faith" if Indemnitee's action is based on the
records or books of account of the Company or relevant enterprise, including
financial statements, or on information supplied to Indemnitee by the officers
of the Company or relevant enterprise in the course of their duties, or on the
advice of legal counsel for the Company or relevant enterprise or on information
or records given or reports made to the Company or relevant enterprise by an
independent certified public accountant or by an appraiser or other expert
selected with reasonable care by the Company or relevant enterprise.  The
provisions of this Section 9(d) shall not be deemed to be exclusive or to limit
in any way the other circumstances in which Indemnitee may be deemed to have met
the applicable standard of conduct set forth in this Agreement.

     (e) The knowledge and/or actions, or failure to act, of any other director,
officer, agent or employee of the Company or relevant enterprise shall not be
imputed to Indemnitee for purposes of determining the right to indemnification
under this Agreement.

     Section 10.  Remedies of Indemnitee.
                  -----------------------

     (a) In the event that (i) a determination is made pursuant to Section 8 of
this Agreement that Indemnitee is not entitled to indemnification under this
Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 7
of this Agreement, (iii) no determination of entitlement to indemnification
shall have been made pursuant to Section 8(b) of this Agreement within ninety
(90) days after receipt by the Company of the request for indemnification, (iv)
payment of indemnification is not made pursuant to Section 5 or 6 of this
Agreement within twenty (20) days after receipt by the Company of a written
request therefor, or (v) payment of indemnification is not made within seven (7)
business days after a determination has been made that Indemnitee is entitled to
indemnification, Indemnitee shall be entitled to an adjudication by the Court of
Chancery of the State of Delaware of his entitlement to such indemnification or
advancement of Expenses.  Alternatively, Indemnitee, at his option, may seek an
award in arbitration to be conducted by a single arbitrator pursuant to the
Commercial Arbitration Rules of the American Arbitration Association.
Indemnitee shall commence such proceeding seeking an adjudication or an award in
arbitration within one hundred eighty (180) days following the date on which
Indemnitee first has the right to commence such proceeding pursuant to this
Section 10(a); provided, however, that the foregoing clause shall not apply in
               --------  -------
respect of a proceeding brought by Indemnitee to enforce his rights under
Section 5 of this Agreement.

     (b) In the event that a determination shall have been made pursuant to
Section 8(b) of this Agreement that Indemnitee is not entitled to
indemnification, any judicial proceeding or arbitration commenced pursuant to
this Section 10 shall be conducted in all respects as a de novo trial, or
                                                        -- ----
arbitration, on the merits and Indemnitee shall not be prejudiced by reason of
that adverse determination.  If a Change of Control shall have occurred, in any
judicial proceeding or arbitration commenced pursuant to this Section 10, the
Company shall have the burden of proving that Indemnitee is not entitled to
indemnification or advancement of Expenses, as the case may be.

     (c) If a determination shall have been made pursuant to Section 8(b) of
this Agreement that Indemnitee is entitled to indemnification, the Company shall
be bound by such determination in any judicial proceeding or arbitration
commenced pursuant to this Section 10, absent (i) a misstatement by Indemnitee
of a material fact, or an omission of a material fact necessary to make
Indemnitee's statement not materially misleading, in connection with the request
for indemnification, or (ii) a prohibition of such indemnification under
applicable law.

     (d) In the event that Indemnitee, pursuant to this Section 10, seeks a
judicial adjudication of or an award in arbitration to enforce his rights under,
or to recover damages for breach of, this Agreement, Indemnitee shall be
entitled to recover from the Company, and shall be indemnified by the Company
against, any and all expenses (of the types described in the definition of
Expenses in Section 17 of this Agreement) actually and reasonably incurred by
him in such judicial adjudication or arbitration, but only if he prevails
therein.  If it shall be determined in said judicial adjudication or arbitration
that Indemnitee is entitled to receive part but not all of the indemnification
or advancement of expenses sought, the expenses incurred by Indemni-

                                      -8-
<PAGE>
 
tee in connection with such judicial adjudication or arbitration shall be
appropriately prorated. The Company shall indemnify Indemnitee against any and
all Expenses and, if requested by Indemnitee, shall (within twenty (20) days
after receipt by the Company of a written request therefor) advance such
expenses to Indemnitee, which are incurred by Indemnitee in connection with any
action brought by Indemnitee for indemnification or advance of Expenses from the
Company under this Agreement or under any directors' and officers' liability
insurance policies maintained by the Company, regardless of whether Indemnitee
ultimately is determined to be entitled to such indemnification, advancement of
Expenses or insurance recovery, as the case may be.

     (e) The Company shall be precluded from asserting in any judicial
proceeding or arbitration commenced pursuant to this Section 10 that the
procedures and presumptions of this Agreement are not valid, binding and
enforceable and shall stipulate in any such court or before any such arbitrator
that the Company is bound by all the provisions of this Agreement.

     Section 11.  Non-Exclusivity; Survival of Rights; Insurance; Subrogation.
                  ------------------------------------------------------------

     (a) The rights of indemnification and to receive advancement of Expenses as
provided by this Agreement shall not be deemed exclusive of any other rights to
which Indemnitee may at any time be entitled under applicable law, the
Certificate of Incorporation, the Bylaws, any agreement, a vote of stockholders
or a resolution of directors, or otherwise.  No amendment, alteration or repeal
of this Agreement or of any provision hereof shall limit or restrict any right
of Indemnitee under this Agreement in respect of any action taken or omitted by
such Indemnitee in his Corporate Status prior to such amendment, alteration or
repeal.  To the extent that a change in the General Corporation Law of the State
of Delaware, whether by statute or judicial decision, permits greater
indemnification or advancement of Expenses than would be afforded currently
under the Company's Bylaws and this Agreement, it is the intent of the parties
hereto that Indemnitee shall enjoy by this Agreement the greater benefits so
afforded by such change.  No right or remedy herein conferred is intended to be
exclusive of any other right or remedy, and every other right and remedy shall
be cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other right or remedy.

     (b) To the extent that the Company maintains an insurance policy or
policies providing liability insurance for directors, officers, employees, or
agents of the Company or of any other corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise which such person serves at the
request of the Company, Indemnitee shall be covered by such policy or policies
in accordance with its or their terms to the maximum extent of the coverage
available for any such director, officer, employee or agent under such policy or
policies.

     (c) In the event of any payment under this Agreement, the Company shall be
subrogated to the extent of such payment to all of the rights of recovery of
Indemnitee, who shall execute all papers required and take all action necessary
to secure such rights, including execu-

                                      -9-
<PAGE>
 
tion of such documents as are necessary to enable the Company to bring suit to
enforce such rights.

     (d) The Company shall not be liable under this Agreement to make any
payment of amounts otherwise indemnifiable hereunder if and to the extent that
Indemnitee has otherwise actually received such payment under any insurance
policy, contract, agreement or otherwise.

     (e) The Company's obligation to indemnify or advance expenses hereunder to
Indemnitee who is or was serving at the request of the Company as a director,
officer, employee, agent and/or fiduciary of any other corporation, partnership,
joint venture, trust, employee benefit plan or other enterprise shall be reduced
by any amount Indemnitee has actually received as indemnification or advancement
of expenses from such other corporation, partnership, joint venture, trust,
employee benefit plan or other enterprise.

     Section 12.  Duration of Agreement.  This Agreement shall continue until
                  ---------------------
and terminate upon the later of:  (a) ten (10) years after the date that
Indemnitee shall have ceased to serve as a director, officer, employee and/or
agent of the Company or of any other corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise which Indemnitee served at the
request of the Company; or (b) the final termination of any Proceeding then
pending in respect of which Indemnitee is granted rights of indemnification or
advancement of expenses hereunder and of any proceeding commenced by Indemnitee
pursuant to Section 10 of this Agreement relating thereto.  This Agreement shall
be binding upon the Company and its successors and assigns and shall inure to
the benefit of Indemnitee and his heirs, executors and administrators.

     Section 13.  Severability.  If any provision or provisions of this
                  ------------
Agreement shall be held to be invalid, illegal or unenforceable for any reason
whatsoever:  (a) the validity, legality and enforceability of the remaining
provisions of this Agreement (including without limitation, each portion of any
Section of this Agreement containing any such provision held to be invalid,
illegal or unenforceable, that is not itself invalid, illegal or unenforceable)
shall not in any way be affected or impaired thereby; (b) such provision or
provisions shall be deemed reformed to the extent necessary to conform to
applicable law and to give the maximum effect to the intent of the parties
hereto; and (c) to the fullest extent possible, the provisions of this Agreement
(including, without limitation, each portion of any Section of this Agreement
containing any such provision held to be invalid, illegal or unenforceable, that
is not itself invalid, illegal or unenforceable) shall be construed so as to
give effect to the intent manifested thereby.

     Section 14.  Exception to Right of Indemnification or Advancement of
                  -------------------------------------------------------
Expenses.  Except as provided in Section 6(a) of this Agreement, Indemnitee
- --------
shall not be entitled to indemnification or advancement of Expenses under this
Agreement with respect to any Proceeding brought by Indemnitee (other than a
Proceeding by Indemnitee to enforce his rights under this Agreement), or any
claim therein prior to a Change in Control, unless the bringing of such
Proceeding or making of such claim shall have been approved by the Board of
Directors.

original but all of which together shall constitute one and the same Agreement.

     Section 16.  Headings.  The headings of the paragraphs of this Agreement

Exchange Act of 1934, as amended (the "Act"), whether or not the Company is then
subject to such reporting requirement; provided, however, that, without
                                       --------  -------
limitation, such a Change in Control shall be deemed to have occurred if after
the Effective Date (i) any "person" (as such term is used in Sections 13(d) and
14(d) of the Act) acquires "beneficial ownership" (as defined in Rule 13d-3
under the Act), directly or indirectly, (other than as a result of an Indirect
Transfer which does not result in a Change in Control of a Stockholder (as each
such term is defined in the Stockholders Agreement) of securities of the Company
representing twenty percent (20%) or more of the combined voting power of the
Company's then outstanding securities without the prior approval of at least
two-thirds of the members of the Board in office immediately prior to such
person attaining such percentage interest or (ii) there occurs a proxy contest,
or the Company is a party to a merger, consolidation, sale of assets, plan of

beneficial owners of securities of the Company representing fifty percent or
more of the combined voting power of the Company's outstanding securities.

     (b) "Corporate Status" describes the status of a person who is or was a

expenses can be provided under this Agreement; except one (i) initiated by an
Indemnitee pursuant to Section 10 of this Agreement to enforce his rights under
this Agreement or (ii) pending on or before the Effective Date.

     (h) "Stockholders Agreement" means that certain Amended and Restated

To:  The Persons Signatory hereto

          Reference is made to the letter agreement and related Term Sheet, each
dated June 4, 1996 (the "Original Term Sheet"), among certain of the parties
hereto relating to At Home Corporation ("@Home").

          As contemplated by the Original Term Sheet, certain of the agreements
contained therein have been superceded by definitive agreements and instruments,
and certain other agreements set forth therein which have not been so superceded
remain as set forth in the Original Term Sheet pending the negotiation and
execution of definitive agreements relating to such matters. In order to confirm
which portions of the Original Term Sheet have been superceded and to amend
certain of the agreements which have not been so superceded, the parties have
determined to amend and restate, effective as of the date hereof, those portions
to the Original Term Sheet which have not been so superceded and remain in
effect. Such remaining provisions of the Original Term Sheet, as so amended and
restated, are attached hereto as Exhibits A and B (collectively, the "Amended
Term Sheet"). The parties hereby confirm their prior agreements to negotiate in
good faith and use their respective reasonable best efforts to execute and
deliver definitive agreements and other instruments implementing the terms set
forth in the Amended Term Sheet. The parties expressly acknowledge and agree
that (i) this letter agreement and the Amended Term Sheet constitute a binding
agreement among them, subject to the terms and conditions set forth in this
letter agreement (other than in the next paragraph below) and in the Amended
Term Sheet, until the definitive agreements incorporating the terms set forth in
the Amended Term Sheet are executed and delivered and (ii) that the Original
Term Sheet, except to the extent amended and restated by the Amended Term Sheet,
has been terminated and superceded in its entirety.

          In addition, pursuant to the Amended and Restated Stockholders
Agreement, dated August 1, 1996, the parties have discussed certain changes in
their relationships in order to facilitate @Home's initial public offering. As a
result, the applicable parties agree that in connection with, and conditioned
upon, the closing of the sale of the Series A Common Stock of @Home pursuant to
the underwriting agreement between @Home, Morgan Stanley & Co. Incorporated and
the other underwriters listed therein, the parties will execute appropriate
instruments adopting the amendments to the Stockholders Agreement set forth on
Exhibit C, the parties will vote all shares of capital stock of @Home owned by
them in favor of the

                                                                    May 15, 1997

amendments to @Home's Certificate of Incorporation set forth in Exhibit D, and
will cause their respective designees on the Board of Directors of @Home to take
such actions as may be necessary to propose and recommend approval by the
stockholders of such amendments to the Certificate of Incorporation and to
approve the amendment to @Home's Bylaws set forth on Exhibit E, in each case
with such additional changes to Exhibits C, D and E as the parties may mutually
agree, so as to cause such amendments to the Stockholders Agreement and to
@Home's Certificate of Incorporation and Bylaws to become effective in
connection with such initial public offering; provided, that the effectiveness
of such amendments to the Stockholders' Agreement and @Home's Certificate of
Incorporation and Bylaws shall be conditioned on the receipt of an opinion of
Delaware counsel to the Company (who shall be reasonably acceptable to the
parties) as to the enforceability of such amended Stockholders' Agreement and
the validity of such amended Certificate of Incorporation and amended Bylaws in
substantially the form set forth as Exhibit F.

          This letter agreement and the Amended Term Sheet attached hereto,
shall be governed by and construed in accordance with the laws of the State of
New York (without regard to its laws pertaining to conflicts of law) applicable
to agreements executed in and to be fully performed entirely in such state.

          If the foregoing is acceptable to you, please execute the copy of this
agreement in the space below, at which time this instrument will constitute a
binding agreement among us.

                                      Very truly yours,

                                      AT HOME CORPORATION

(c)  Reasonable Commercial Efforts.
     ----------------------------- 

Any reference herein to an obligation to use "all commercially reasonable
efforts," "reasonable commercial efforts" or any similar level of effort shall
mean an obligation to use commercially reasonable efforts, and no difference in
the language expressing any such level of effort shall imply any substantively
different obligation; provided, however, that the term "reasonable best efforts"
                      --------  -------                                         
as used in Section 7(a), 13(b) and 15 hereof shall be deemed to require a level
of effort on the part of @Home which is significantly greater than the level of
effort required to satisfy its obligations under a standard requiring use of
"commercially reasonable efforts."

The party (the "Obligated Party") that is obligated to utilize "reasonable best
                ---------------                                                
efforts" with respect to any matter shall immediately notify (the "Failure
                                                                   -------
Notice") each party (an "Affected Party") to which the Obligated Party is so
- ------                   --------------                                     
obligated if the Obligated Party determines that it is not able to accomplish
the matter with respect to which it is obligated to use such reasonable best
efforts.  If any Affected Party (the "Notifying Party") notifies the Obligated
                                      ---------------                         
Party in writing that the Notifying Party believes that the Obligated Party has
not used its reasonable best efforts as to any 

                                     -11-
<PAGE>
 
applicable matter, the Obligated Party shall provide a written response to the
Notifying Party and to each other Affected Party within two Business Days (as
defined in the Stockholders' Agreement). Any Affected Party shall be entitled to
initiate binding arbitration with respect to matters related to the obligation
to use reasonable best efforts with CableLabs as the arbitrator. If CableLabs is
unwilling or unable to act as arbitrator, any Affected Party shall be entitled
to submit the matter to arbitration before the American Arbitration Association
("AAA") in accordance with AAA's then applicable rules and procedures. Any
  ---
arbitration shall be conducted in New York, New York or at such other location
that may be selected by mutual agreement of the Obligated Party and each
Notifying Party as to such matter. The parties shall utilize the most expedited
form of arbitration available with the intent that the matter be resolved within
30 days after submission to the extent practicable. The cost of arbitration
shall be borne by the non-prevailing party (as determined by such arbitrator).
To the extent such arbitration results in a decision that the Obligated Party
has not used its reasonable best efforts and such decision specifies an action
to be taken which would constitute such reasonable best efforts, the Obligated
Party shall thereafter be required to take such action. The prevailing party
shall be entitled to enter a judgment with respect to the arbitrator's
determination (which may provide for money damages and/or other forms of legal
and/or equitable relief) in any court of relevant jurisdiction and all parties
shall be fully bound by the arbitrator's determination. Nothing herein shall
limit the right of any party to seek equitable relief in any court of relevant
jurisdiction.

2.   CREATION OF MASTER ROLL-OUT SCHEDULE.

In connection with the establishment of @Home's periodic budget and business
plan and the periodic amendments to @Home's Business Plan contemplated hereby,
each Cable Parent shall deliver to @Home a list of Offered Homes Passed (and the
related cable systems) and Projected Commencement Dates for such Offered Homes
Passed.  Such list shall include, by separate designation, those Offered Homes
Passed which are Qualifying Offered Homes Passed.  Thereafter, the Cable Parents
and @Home shall cooperate in good faith to establish a timetable and schedule in
order to coordinate the Cable System Upgrade plans of each Cable Parent with the
Network Upgrade plans of @Home so as to attempt to make the @Home Services
available to the Offered Homes Passed on or before the applicable Projected
Commencement Date in an efficient and economical manner; provided, however, that
                                                         --------  -------      
such timetable and schedule shall be determined (i) by giving priority to making
the @Home Services available to those Offered Homes Passed which are Qualifying
Offered Homes Passed, (ii) in accordance with the respective Projected
Commencement Dates relating to such Qualifying Offered Homes Passed and (iii) in
proportion to the respective number of Qualifying Offered Homes Passed of such
Cable Parents.  The schedule determined and approved by the Board of @Home in
accordance with the foregoing criteria shall be the "Master Roll-Out Schedule"
                                                     ------------------------
(together with any modifications and adjustments within the applicable Planning
Period agreed to by @Home and the applicable Cable Parent following the adoption
of the Master Roll-Out Schedule), which shall include, for each Cable Partner,
specific plans related to the cable systems to be upgraded, the number of
Offered Homes Passed and Qualifying Offered Homes Passed therein and the
Proposed Commencement Date therefor, together with such additional information
as the parties may agree. Subject to any subsequent adjustments within the
applicable Planning Period as may be agreed to by the applicable Cable Parent
and @Home, the information set forth therein (x) as to a Cable Parent, shall
constitute its representation to @Home that such Cable Parent reasonably
believes that the applicable Offered Homes Passed will be made available for
distribution of the @Home Services by the applicable Projected Commencement
Dates, and (y) as to @Home, shall constitute @Home's agreement to use
commercially reasonable efforts to cause the @Home Network to be upgraded in
such a way as is necessary in order to cause the @Home Services to be available
for distribution to such Qualifying Offered Homes Passed by the applicable
Projected Commencement Dates.

3.   EXECUTION OF LOCAL CABLE OPERATOR DISTRIBUTION AGREEMENTS.

Immediately following the establishment of the Master Roll-Out Schedule for each
Planning Period, each Cable Parent shall cause those of its Affiliated Operators
which own and operate cable systems serving the Offered Homes Passed which have
a Projected Commencement Date during such Planning Period to enter into a LCO
Agreement with @Home.  Each such LCO Agreement shall incorporate therein the
relevant matters from the Master Roll-Out Schedule, including but not limited
to, the number of Offered Homes Passed for such Operator Territory and the
related Projected Commencement Dates.

                                     -13-
<PAGE>
 
4.   BUDGETS.

(a)  @Home will use commercially reasonable efforts to cause the @Home Services
to be available to all Qualifying Offered Homes Passed of the Cable Parents
having Projected Commencement Dates within such Planning Period and will use
commercially reasonable efforts to comply with the Master Roll-Out Schedule for
such Planning Period.

(b)  The adoption of a Non-Pro Rata Roll-Out Budget shall require a
Supermajority Vote (as defined in the Charter). A Stockholder who has been
treated in a non-pro rata manner with respect to a Roll Out Budget and has not
voted in favor of such Non-Pro Rata Roll-Out Budget, shall be entitled to a
written explanation of such treatment from the Chief Executive Officer and each
director who has voted in favor of such Non-Pro Rata Roll-Out Budget.

(c)  In the event a Cable Parent believes that any Roll-Out Budget approved by a
majority of the Board constitutes a Non-Pro Rata Roll-Out Budget, such Cable
Parent shall promptly notify the Board of such belief and present evidence of
such claim.

5.   CABLE PARENT EXCLUSIVITY PROVISIONS.

                                     -15-
<PAGE>
 
(a)  During the Restricted Period, no Cable Parent will, and each Cable Parent
will cause any Person that is or shall become a Controlled Affiliate of such
Cable Parent not to, directly or indirectly (i) conduct or engage in any
Restricted Business (as defined below), (ii) participate (whether by means of a
management, advisory, operating, consulting or similar agreement or arrangement)
in any Restricted Business, or (iii) have any record or beneficial equity
interest, either as a principal, trustee, stockholder, partner, joint venturer
or otherwise, in any Person which so conducts, engages in or participates in,
any Restricted Business. Notwithstanding the foregoing, the provisions of this
Section 5 shall not: (x) prevent the beneficial ownership for investment
purposes of 10% or less of any class of equity securities of any such Person
which is a Public Company; (y) prevent any Exempt Acquisition (as defined
below), the operation of any Exempt Restricted Assets (as defined below) or any
Non-Control Acquisition (as defined below) (in each case, subject to compliance
with the other provisions hereof); and (z) be applicable to any Restricted
Business in which a Cable Parent or its Controlled Affiliate engaged or
participated in, or in which such Cable Parent or Controlled Affiliate
beneficially owns any equity interests, in each case as of the Execution Date;
provided, that the level or scope of such Person's engagement, participation or
- --------
equity ownership is not increased during the Restricted Period other than in
accordance with instruments or agreements which were in effect on the Execution
Date. In addition, the provisions of this Section shall not be applicable with
respect to any Operator Territory to the extent that the Cable Parent
Exclusivity Provisions (as defined below) have been terminated as to such
Operator Territory or following the expiration of the Term (as defined in the
LCO Agreement) of the applicable LCO Agreement; provided, however, that
                                                --------  -------
regardless of any release of an Operator under an LCO Agreement with respect to
a specified Operator Territory, the restrictions set forth in clause (iii) of
the first sentence of this Section 5 (a) shall continue nonetheless to be
applicable to such released Operator for the applicable Restricted Period. For
purposes of this MDA Term Sheet, the term (A) "Non-Control Acquisition" shall
                                               -----------------------
mean any acquisition of beneficial ownership of equity securities of any Person
which are registered under the Exchange Act, if none of such Cable Parent or any
Controlled Affiliate of such Cable Parent shall Control or be under common
Control with such Person, and (B) "Restricted Business" shall mean (1) the
                                   -------------------
provision of a residential Internet Service over the cable television plant or
equipment of any Cable Parent or its Controlled Affiliates at bit rate speeds
greater than 128 kbps whose primary purpose is the provision to consumers of
entertainment, information content, transactional services or e-mail, chat and
news groups or substantially similar services (a "Consumer Purpose"), (2) the
                                                  ----------------
connection by any Cable Parent or any Controlled Affiliate thereof of its cable
television plant and equipment directly or indirectly to any Internet Backbone
for a Consumer Purpose at bit rate speeds greater than 128 kbps, or (3) the
business of providing or engaging in any Internet Backbone Service, in each of
the above cases of clauses (1), (2) and (3), (x) other than any such service to
be offered by @Home and (y) within the United States of America; provided,
however, that notwithstanding the provisions of clauses (1) and (2) of
subsection (B) above (and regardless whether or not such service or other
activity is otherwise within the definition of the term "Restricted Business"),
"Restricted Business" shall not include: (i) the creation or aggregation of
content; (ii) the provision by any Cable Parent of telephony services (i.e., the
provision of conventional telephone service, including POTS and ISDN) to its
subscribers, provided that any use of or connection to any Internet Service in
connection with the provision of such telephony services shall be (x) pursuant
to a subscriber dial-up of an Internet Service provider and (y) at bit rate
speeds of 128
                                     -16-
<PAGE>
 
kbps and below; (iii) the provision of services which are primarily work-related
("Internet Work Services"); (iv) the provision of any Internet Services not
  ----------------------
using a Cable Parent's cable television plant; (v) the provision of any Internet
Service that is a Local Service; (vi) the provision of services which are
primarily utilized to connect students to schools, colleges and universities;
and (vii) the provision of Internet telephony, Internet video telephony, or
Internet video conferencing; (viii) the provision of Internet Services (x) which
are primarily intended for display on a television (provided that any Internet
Service that is displayed on a computer monitor or television that also
functions as a display device for a personal computer shall not be deemed to be
primarily intended for display on a television unless such personal computer is
equipped with a television tuner and such personal computer is functioning as a
television display device through such monitor or television at such time as the
Internet Services are provided) and (y) that provide the user with no more than
limited access to the Internet that is of a type and quality that is
substantially less comprehensive than that offered by a typical Internet service
provider (such as AOL, CompuServe, Netcom or WebTV); (ix) the provision of
primarily downstream Internet Services where the user cannot send commands in
the upstream direction by means of telecommunications connectivity to the source
of such downstream Internet Services in real-time (i.e., with typical latencies
of less than five minutes); or (x) the provision of Video Services. In addition,
notwithstanding the prohibitions set forth in this Section 5(a), each Cable
Parent shall be entitled to engage or participate in limited testing, trials and
similar activities with respect to any Restricted Business so long as (I) such
engagement or participation is solely for testing or trial purposes, (II) such
Cable Parent makes any such service available to a limited number of Homes
Passed (as defined in the Stockholders' Agreement) (which shall not exceed
50,000 in the aggregate), (III) the duration of such testing or trial does not
exceed six months and (IV) the public disclosures made by such Cable Parent
shall not characterize or represent such service as other than a test or trial.
Each Cable Parent agrees that, subject to any applicable confidentiality
obligations, it will advise @Home of its intention to conduct such testing,
trial or other activity, and @Home and each Cable Parent agree to discuss in
good faith arrangements to conduct such testing or trial jointly, provided that
neither party shall be under any obligation to agree to any joint testing
arrangements.

(b)  In the event that, during the Restricted Period, any Cable Parent or any of
its Controlled Affiliates desires to enter into or conduct any business in the
United States which would not be a Restricted Business but which requires the
utilization or other implementation of both the cable plant of such Cable Parent
or its Controlled Affiliates and an Internet Backbone Service, then such Cable
Parent or its Controlled Affiliate shall first offer to @Home the opportunity to
provide such Internet Backbone Service in accordance with the provisions of this
Section 5 (b); provided that neither such Cable Parent nor its Controlled
               --------
Affiliate shall be obligated to make such offer if the business to be conducted
or entered into would involve obtaining the Internet Backbone Service from a
Person or group of Persons that is offering to provide such service or cause
such service to be provided only in a package with other products or services
that are integral to such other business. Notwithstanding the foregoing proviso,
nothing herein contained shall be deemed to modify any Cable Parent's
obligations pursuant to Section 5 (a). Such offer shall include a specification
of the requirements for such Internet Backbone Service and a good faith estimate
of the most favorable terms and conditions on which such Internet Backbone
Service is available to such Cable Parent or its Controlled Affiliate from third
parties. If @Home

                                     -17-
<PAGE>
 
proposes to provide such Internet Backbone Service within a reasonable period of
time following such offer, then, the Cable Parent or its Controlled Affiliate
and @Home will negotiate in good faith the terms and conditions under which
@Home would provide such Internet Backbone Service. Unless the terms and
conditions upon which @Home is to provide such service following such
negotiation are less favorable to such Cable Parent or its Controlled Affiliate
than those available from a third party, then such Cable Parent or Controlled
Affiliate shall select @Home to provide such Internet Backbone Service on such
terms and conditions so offered. In consideration of the Cable Parent's
agreement to provide @Home such opportunity to provide such Internet Backbone
Service, @Home agrees that it will not propose to provide such Internet Backbone
Service unless it reasonably believes that it is able to provide the Internet
Backbone Service so requested.

(c)(i)  In the event that at any time during the Restricted Period, a Cable
        Parent and/or any Person that is or shall become a Controlled Affiliate
        such Cable Parent, shall acquire beneficial ownership of at least a
        majority of the then outstanding voting power of any Person, which such
        Person is not principally engaged in any Restricted Business, but
        nonetheless, directly or indirectly, owns, leases or otherwise operates
        facilities (the "Exempt Restricted Assets") which, if operated
                         ------------------------                     
        independently, would constitute a Restricted Business (an "Exempt
                                                                ------
        Acquisition"), the provisions of this Section 5 (c) shall be applicable
        -----------                                                            
        such Exempt Restricted Assets.  In the event that at any time during the
        Restricted Period, a Non-Control Acquisition shall occur and if at any 
        during the Restricted Period the beneficial ownership of equity security
        giving rise thereto shall cease to qualify as a Non-Control Acquisition
        any reason, a "Control Acquisition" shall have occurred and then the
                       -------------------                                  
        provisions of this Section 5 (c) shall be applicable to the assets and
        business of the Person which is the subject of such Control Acquisition
        which, if operated independently would constitute a Restricted Business
        (the "Control Restricted Assets," and together with any Exempt Restrict
              -------------------------                                        
        Assets, the "Restricted Assets").
                     -----------------   

(ii)    In the event of any Exempt Acquisition or any Control Acquisition, the
        applicable Cable Parent will (and will cause any Person which is or
        shall become a Controlled Affiliate of such Cable Parent to) use
        reasonable commercial efforts to divest any Restricted Assets so
        acquired unless such divestiture would be adverse to the tax structure
        of any Exempt Acquisition or Control Acquisition; provided, however,
        that such Cable Parent shall be required to use reasonable commercial
        efforts to divest such assets within a reasonable period following the
        time such divestiture would not be adverse to the tax structure of such
        acquisition, in which event all parties would reasonably cooperate to
        cause such divesture to be accomplished on a tax-efficient basis. Such
        reasonable commercial efforts shall be deemed to include an auction of
        such Restricted Assets. Notwithstanding the foregoing, such Cable Parent
        will not be required to dispose of such Restricted Assets if it would
        not realize the fair market value thereof (it being agreed that the fair
        market value thereof will be computed by reference to the overall
        acquisition price in the Exempt Acquisition or Control Acquisition). The
        provisions of clauses (iii), (iv) and (v) of this Section 5 (c) shall
        apply to any such disposition.

(iii)   Such Cable Parent shall not, and shall not permit any Person which is or
        shall become a 

                                      -18
<PAGE>
 
     Controlled Affiliate of such Cable Parent to, sell, transfer
     or otherwise dispose of all or any substantial portion of such Restricted
     Assets, unless prior to any such sale, transfer or other disposition, such
     Cable Parent shall have offered by written notice to sell to @Home (or its
     Controlled Affiliate) all or such portion of the Restricted Assets at a
     specified price (the "Offer Price") and shall have allowed such offer to
                           -----------                                       
     remain open and available for acceptance for a period of at least 30
     calendar days.  In the event that such offer is not accepted within such
     30-day period, such Cable Parent or such Controlled Affiliate shall be free
     to offer such Restricted Assets to any other Person, provided, however,
                                                          --------  ------- 
     that such Cable Parent shall not, and shall not permit any Person which is
     or shall become a Controlled Affiliate of such Cable Parent to, offer to
     sell, transfer or otherwise dispose of such Restricted Assets, and shall
     not sell, transfer or otherwise dispose of any of such Restricted Assets,
     for a price less than the Offer Price or on terms which are more favorable
     to such offeree than the terms on which such Restricted Assets were offered
     to @Home, in either case without first complying again with the provisions
     of this clause (iii).

(iv) In the event that @Home shall accept any such offer described in clause
     (iii), the closing of the purchase of the Restricted Assets shall take
     place at the principal office of such Cable Parent on the later of (x) the
     fifth business day after the expiration of the 30-day period after the
     giving of the notice set forth in clause (iii), and (y) the fifth business
     day after the receipt of any required governmental approval or the
     expiration or termination of any waiting period, including any waiting
     period pursuant to the Hart-Scott-Rodino Antitrust Improvements Act of
     1976, as amended (the "HSR Act").
                            -------   

(v)  The foregoing provisions of this subsection (c) shall be applicable to
     successive transfers or other dispositions of all or any portion of the
     Restricted Assets by such Cable Parent or any Person which is or shall
     become a Controlled Affiliate of such Cable Parent.

The provisions of this section are referred to herein as the "Cable Parent

- ----------------------                                                    
Exclusivity Provisions shall automatically terminate as to the applicable
Operator Territory upon the consummation of the sale or transfer of such cable
television system by a Cable Parent or its Controlled Affiliate to a third party
(other than a third party which is a Cable Parent or a Controlled Affiliate of a
Cable Parent).

as to all Subject Shares held by the Comcast Stockholder Group (except to the
extent that the @Home Repurchase Right has been previously exercised or is then
exercisable as to any of such Subject Shares in connection with the exercise of
the Comcast Non-Exclusive Right). In the event that Comcast elects to
irrevocably terminate its right to exercise the Comcast Non-Exclusive Right at
any time prior to such time as the @Home Repurchase Right has become exercisable
as a result of the exercise of the Comcast Non-Exclusive Right, it shall deliver
an instrument to such effect to @Home whereupon the @Home Repurchase Right and
Comcast's right to exercise the Comcast Non-Exclusive Right shall terminate.

(c)  Notwithstanding any other provision contained in this MDA Term Sheet or in
the Stockholders' Agreement, until the earlier to occur of (i) such time as none

event of an exercise of the Comcast Non-Exclusive Right or (ii) such time as
Comcast irrevocably terminates its right to exercise the Comcast Non-Exclusive
Right pursuant to the last sentence of Section 6(b), neither Comcast Sub nor any
member of the Comcast Stockholder Group shall be entitled to Transfer (other
than to another member of the Comcast Stockholder Group that agrees to be bound
by the provisions of this MDA Term Sheet and the Stockholders' Agreement) any
Subject Shares that would be subject to the @Home Repurchase Right were Comcast
Cable to exercise the Comcast Non-Exclusive Right.

(d)  Nothing herein shall limit the right of any member of the Comcast
Stockholder Group to sell shares of Series A Common Stock pursuant to Section
4.5 of the Stockholders' Agreement without regard to whether such shares are
Subject Shares, and the @Home Repurchase Right shall terminate as to any such
shares so sold; provided, that in connection with any such sale, Comcast shall

be deemed to have sold first those Company Securities not subject to the @Home
Repurchase Right. After such a sale, the @Home Repurchase Right shall continue
as to any Subject Shares not so sold and the Comcast Non-Exclusive Right shall
remain in effect without modification.

        as a result of the event specified in clause (y) below) or (y) in the
        event the applicable Cable Partner ceases to be an Exclusive Stockholder
        as a direct result of a termination of the Cable Parent Exclusivity
        Provisions in connection with a TCI Performance Default, the sixth

        applicable law and the other terms and conditions of this MDA Term Sheet

        Controlled Affiliates will (A) offer or provide Internet Services (or
        any comparable services with comparable capabilities) at bit rate speeds
        of greater than 128 kbps to residences (including, without limitation,

        geographic area served by the cable systems owned by a Cable Parent
        whose Stockholder Group includes an Exclusive Stockholder (an "Exclusive

        other than through the use of the Operator Facilities of such Exclusive
        Cable Parent and its Controlled Affiliates pursuant to, or as otherwise
        contemplated by, this MDA Term Sheet, or (B) offer, provide or

        limitation, individual dwelling units within a multiple dwelling unit)
        in the Exclusive Territory, or (C) advertise, promote or market, or

        Exclusive Cable Parent; provided, however, that subject to @Home's
                                --------  -------
        compliance with the provisions of clauses (B) and (C) above, @Home shall
        not incur liability to any Cable Parent or Affiliated Operator in the
        event that subscribers in any such Exclusive Territory obtain access to
        such Excluded Services by utilizing the capabilities of the @Home
        Service. To the extent that any such Cable Parent grants @Home consent
        to promote, offer or distribute any Excluded Service in the Operator
        Territory of any of its Affiliated Operators, the terms and provisions
        upon which such Excluded Service shall be distributed (including the
        compensation payable to @Home in respect thereof) shall be as the
        parties may agree; provided, however, that the terms and provisions of

        applicable to @Home set forth in subsection (a)(i) above with respect to
        the offer, provision or distribution of Video Services in any Exclusive
        Territory, @Home will not initially offer, provide, distribute,
        advertise, promote or market any Video Service in any individual Area of
        Dominant Influence ("ADI") (as such term is defined by the Federal
        Communications Commission) which, as of the date of the initial offering
        of Video Services to @Home subscribers located in such ADI, includes an
        Exclusive Territory of a Cable Parent, unless it shall have received the
        prior written consent of a Supermajority of the Affected Cable Parents;
        provided, that (A) @Home will be entitled to seek the foregoing consent
        of the applicable Affected Cable Parents as to any ADI on multiple
        occasions (notwithstanding any prior refusal of the applicable Affected
        Cable Parents at the time of any such prior refusal to give such
        consent), (B) no such consent shall be required as to any ADI at any
        time when there are no Affected Cable Parents as to such

        ADI (notwithstanding whether one or more Cable Parents subsequently
        becomes an Affected Cable Parent as to such ADI), and (iii) the
        effectiveness of any such consent shall not be affected by any
        subsequent acquisition or disposition of cable systems by one or more
        Cable Parents (or other events affecting the number of cable television
        subscribers) in the applicable ADI. The term "Supermajority of Affected

        -------------
        of the number of cable television subscribers located in such ADI of all
        Cable Parents having an Exclusive Territory within such ADI (each such
        Cable Parent, an ("Affected Cable Parent")

(iii)   For purposes of this Section 7(a), (x) @Home's agreement not to offer,
        provide or distribute any Video Service shall require it to use its
        reasonable best efforts to block or otherwise impair a user's ability to
        connect to any such Video Service through the @Home Service, to provide
        notice to the applicable Cable Parent to the extent @Home determines
        that subscribers of such Cable Parent are in fact connecting to any such
        Video Service and to provide all Cable Parents with any software or
        other technology which becomes available to @Home to monitor or block
        such usage of Video Service and (y) restrictions set forth in this
        Section 7(a) with respect to Excluded Services shall not be applicable
        to Internet Work Services which do not offer or make available services
        to residences. The provisions of this Section 7(a) are hereinafter
        referred to collectively as the "@Home Exclusivity Provisions."
                                          ----------------------------  

(iv)    @Home acknowledges and agrees that each LCO Agreement entered into
        following May 15, 1997 will contain a provision in which the applicable
        Operator acknowledges and agrees to the existence and enforcement of the
        @Home Exclusivity Provisions (including the enforcement of the rights of
        any Affected Cable Parent(s) pursuant to clause (ii) above) as to any
        ADI(s) containing all or a portion of the applicable Operator Territory,
        and agrees that such Operator will not sue or threaten to sue, or seek
        or attempt to cause any person to commence or threaten any governmental
        or regulatory action or investigation against @Home or any Cable Parent
        as a result of or in connection with the enforcement of the @Home
        Exclusivity Provisions (including the provisions of such clause (ii)).

(b)  The provisions of Section 7(a) shall not be applicable with respect to any
Operator Territory to the extent that the @Home Exclusivity Provisions have
been terminated as to such Operator Territory or following the expiration
of the Term of the applicable LCO Agreement.

8.   NON-PERFORMANCE OF TCI.

In the event that TCI shall be in Performance Default on June 4, 1999 (the
                                                                          
"First Determination Date"), then the applicable Triggering Cable Parent (as
- -------------------------                                                   
defined below), if any, shall, by written notice to @Home, TCI and each other
Cable Parent, delivered within 60 days of the First Determination Date, be
entitled to terminate the Cable Parent Exclusivity Provisions as to all Cable
Parents and their Controlled Affiliates, such termination to be effective as of
the date of such notice.  In the event that there is a Performance Default on
the First Determination Date but the applicable Triggering Cable Parent does not
elect to terminate the Cable Parent Exclusivity Provisions within the period
specified above, then following each succeeding anniversary thereafter during
the Restricted Period (each such anniversary, a "Subsequent Determination Date")
                                                 -----------------------------  
upon which TCI shall be in Performance Default, the applicable Triggering Cable
Parent, if an Eligible Cable Parent, shall have the right, exercisable by
written notice to @Home, TCI and each other Cable Parent, delivered within 60
days of such Subsequent Determination Date to terminate the Cable Parent
Exclusivity Provisions.  The term "Triggering Cable Parent" shall mean the High

C as of the applicable date of determination or, if one of Comcast Cable or CCI
(a) is no longer an Eligible Cable Parent or (b) is acquired by TCI, the
remaining Eligible Cable Parent or Cable Parent not acquired by TCI, as the case
may be, between Comcast Cable and CCI.  An "Eligible Cable Parent" shall mean
                                            ---------------------            
any Cable Parent which is a member of a Stockholder Group which includes an
Eligible Stockholder.

9.   MOST FAVORED NATIONS PROVISIONS.

Each Cable Parent and its Controlled Affiliates will be entitled to "most
favored nation" ("MFN") (a) terms and conditions of carriage with respect to the
                  ---                                                           
distribution of the @Home Services or any services provided to an Eligible Cable
Parent pursuant to Section 18(c) below (which distribution or other services for
purposes of this Section 9 shall not include the distribution or promotion of a
content provider's services) and (b) terms and conditions of the Trademark
License Agreement (as defined below), and any Ancillary Services Arrangements
(as defined in the LCO Agreement), in each case, including all direct and
indirect benefits as a result of a transaction with @Home that are no less
favorable than those offered to any other Operator, individually or collectively
from time to time.  Such MFN status shall require identical treatment of all
Cable Parents and their respective Controlled Affiliates (without regard to the
size (through volume discounts or otherwise) or identity of such Cable Parent or
its ownership of @Home securities) (x) with respect to the terms of the
distribution arrangements (including the Trademark License Agreement and any
Ancillary Services Arrangements) (other than the duration of any distribution
agreement arising from the provisions of the Term of the LCO Agreement) granted
to any Cable Parent and its Controlled Affiliates and (y) with respect to all of
the terms of such distribution arrangements provided to third party providers
which are not members of a Stockholder Group (an "Unaffiliated Third Party"),
                                                  ------------------------   
other than with respect to (i) whether @Home requires that an unaffiliated
Operator agree to provisions similar to the Cable Parent Exclusivity Provisions
as to the applicable Operator Territory, (ii) the level of commitment related to
the Cable System Upgrade and the remedies of @Home in the event of any failure
to upgrade such systems by the Projected Commencement Date, (iii) percentage
splits granted to Unaffiliated Third Parties in the event the Board of @Home, by
a Required Either E Cable Parent Election (as defined in the LCO Agreement),
elects to increase the percentage split to @Home (in which case the percentage
split to @Home would be so increased with respect to all future periods with
respect to all Operators which are Cable Parents or Controlled Affiliates of a
Cable Parent with respect to any existing LCO Agreement (regardless of the
existing provisions thereof) or any LCO Agreement entered into in the future,
while the LCO Agreements of Unaffiliated Third Parties in effect at the time of
such change would not be so affected), and (iv) the duration of any distribution
agreement.  In addition, each Cable Parent and its Controlled Affiliates shall
be entitled to MFN status with respect to the terms of any sales agency
agreement pursuant to which it is authorized to enter into .Com Agreements on
behalf of @Home.

10.  CHANGE OF CONTROL OF TCI.

Following the occurrence of a TCI Change of Control, either CCI or Comcast
Cable, so long as it is an Exclusive Stockholder, shall be entitled to elect to
terminate the Restricted Period as to all Cable Parents and their Controlled
Affiliates by giving written notice to such effect to each other Stockholder and
@Home, in which case no Cable Parent or its Controlled Affiliate shall have any
remaining obligations under the Cable Parent Exclusivity Provisions.

11.  CHANGES IN MASTER ROLL-OUT SCHEDULE.

If a Cable Parent determines that it or one of its Controlled Affiliates will
not be able to fulfill its commitment with respect to the commencement of the
availability of the @Home Services as of the Projected Commencement Date, it
will immediately notify @Home, and, if such notice is given at least 180 days
prior to the applicable Projected Commencement Date, the Cable Parent shall be
entitled to substitute one or more other cable systems having substantially the
same number of Homes Passed as were required to be delivered by such date for
commencement of the @Home Services on that Projected Commencement Date, subject
to the approval of @Home, which will not be unreasonably withheld so long as the
substitute systems have similar characteristics in terms of number of Homes
Passed and will not cause a material increase in @Home's expenses or have a
material adverse impact on @Home's ability to meet its other commitments under
the Master Roll-Out Schedule, in which case such substitute cable systems shall
retain the same roll out priority and Projected Commencement Date as the cable
systems they replaced.  For purposes of the foregoing sentence, the substitution
of any cable systems that are not Qualifying Systems will be deemed to have such
an impact unless such cable systems are located in an area included in the
current Master Roll-Out Schedule or in which @Home has already commenced
offering the @Home Services.  Any changes to the Master Roll-Out Schedule
pursuant to this paragraph shall be incorporated in the affected LCO Agreements,
and the applicable Cable Parent shall cause the Operator of any such substituted
cable system to enter into an LCO Agreement.  Notwithstanding the foregoing,
nothing herein shall limit the right of a Cable Parent or its Affiliated
Operator, at any time prior to the Commencement Date (as defined in the LCO
Agreement), to remove any of its cable systems from the Master Roll-Out Schedule
and/or terminate any existing LCO Agreement in respect thereof, subject to its
obligations set forth in such LCO Agreement (including, but not limited to, the
payment to @Home of the @Home Specified Remedy (as defined in the LCO Agreement)
and the release of @Home from the @Home Exclusivity Provisions with respect to
such Operator Territory).

12.  LOCAL CONTENT PROGRAMMING.

Each Operator, as to its cable system, or each Cable Parent, as to one, several
or all cable systems owned by it and its Controlled Affiliates, shall be
entitled to create, author, promote and otherwise engage in the business related
to Local Content offerings.  Within the @Home First Page, each Affiliated
Operator shall be allocated the Local Area.  Each Affiliated Operator or Cable
Parent, as the case may be, shall be entitled to program its Local Area as it
shall determine in its sole discretion, subject only to the Style Guidelines (as
defined in the LCO Agreement).

                                     -26-

13.  @HOME PROGRAMMING.

(a)  @Home shall be entitled to create, author and promote such content provider
offerings as it shall determine, and shall have the right to program the
National Area in its sole discretion, subject to the Cable Parent Exclusion
Right, the Cable Parent Access Blocking Right and the provisions of Sections 7
and 13(b). @Home and each Cable Parent will use commercially reasonable efforts
to cooperate with each other in the creation of the @Home First Page (including
the coordination of the programming of the National Area and each Local Area) so
as to optimize the consumer appeal of the @Home web site.

(b)  @Home agrees that it will use its reasonable best efforts to (i) consult
with and involve each of the Cable Parents in the development of requirements
for and design of enhancements to the @Home Service and new features and new
applications proposed to be included in the @Home Service (collectively,
"Enhancement and Addition") and (ii) coordinate closely with each Cable Parent
 ------------------------
with respect to the introduction of any Enhancement and Addition which would or
could have a significant effect upon the operations or business of the Cable
Parent with respect to its delivery of the @Home Service to its customers,
including, but not limited to, effects upon network transmission operations,
customer service operations or marketing operations. In addition, @Home will
notify each Cable Parent not less than 60 days prior to the proposed date of
introduction of such Enhancement and Addition with respect to such proposed
introduction date and all material details related thereto. In the event that
@Home receives not later than the 30th day preceding such proposed introduction
date, from Cable Parents representing a majority of the aggregate number of
Residential Subscribers of all of the Cable Parents, written notice objecting to
such Enhancement and Addition, @Home shall postpone the introduction of the
Enhancement and Addition in the Operator Territories of the objecting Cable
Parents, and shall thereafter negotiate with all Cable Parents and use its
commercially reasonable efforts to implement such changes as @Home and such
Cable Parents agree are necessary in order to cure such objections. Upon
reaching agreement with Cable Parents representing a majority of the aggregate
number of Residential Subscribers of all of the Cable Parents, @Home shall
thereafter introduce such Enhancements and Addition to the @Home Service.
Notwithstanding the foregoing, the provisions of this Section 13(b) shall be
subject in all respects to the provisions of Section 7(a).

14.  EXECUTION OF PROMOTIONAL AGREEMENTS AND EXERCISE OF CABLE PARENT EXCLUSION
RIGHT.

(a)  Each Promotional Agreement shall provide that such content provider's right
to presentation on the National Area shall be subject to the exercise of the
Cable Parent's Exclusion Right and to @Home=s obligations with respect to the
@Home Exclusivity Provisions. Upon execution of a Promotional Agreement, @Home
shall provide written notice thereof by fax or e-mail to a designated contact
person at each Cable Parent. Such written notice shall include (i) the identity
of the content provider, (ii) a description outlining in reasonable detail the
content to be offered by such provider, (iii) the position in the National Area
to be assigned to such content provider, and (iv) an outline of the other terms
and conditions of such Promotional Agreement. Each Cable Parent will thereafter
have the right to exercise its Cable Parent Exclusion Right with respect to
Specified Promotions as to some or all of its Affiliated Operators distributing
the @Home Service. In order to exercise such right, the Cable Parent shall
deliver reasonable notice of its exercise of the Cable Parent Exclusion Right to
@Home which will become effective within a reasonable period of time after such
notice.

(b)  An exercise of the Cable Parent Exclusion Right shall result in (x) the
exclusion from the National Area of any or all Specified Promotions (as defined
below) with respect to a Specified Brand (as designated by the applicable Cable
Parent) and (y) the replacement of such promotions (e.g., replacement of the
excluded "button") by other promotions of the same type (e.g., replacement of an
excluded button with another button) as selected by @Home.

(c)  The term "Specified Promotions" shall mean any or all promotions in the
               --------------------
National Area relating to the Specified Brand of a content provider (as
designated by the applicable Cable Parent). A "Content Provider Group" shall
                                               ----------------------
mean a content provider that has entered into one or more Promotional Agreements
for the purpose of placing Specified Promotions in the National Area with
respect to a number of Specified Brands. The term "Specified Brand" means one or
                                                   ---------------
more substantially similar brand names utilized by a content provider in
connection with the promotion of its business identified by such brand name(s).
By way of example, Turner Broadcasting System, Inc. ("TBS") and its subsidiaries
                                                      ---
would be considered a Content Provider Group; WTBS and TNT would be considered
to be two Specified Brands because they represent distinct brand names (albeit
in the same line of business). A Cable Parent electing to exercise its Cable
Parent Exclusion Right with respect to WTBS and TNT would be deemed to have
excluded two Specified Promotions to the extent that it elected to exclude both
WTBS and TNT. Similarly, a Cable Parent electing to exercise its Cable Parent
Exclusion Right with respect to a content provider which elected to use only one
Specified Brand to promote several related sites using substantially similar
brand names (for example, QVC Diamonds, QVC Clothes, QVC Electronics, etc.)
would be deemed to have exercised its exclusion right with respect to one
Specified Brand.

(d)  A Cable Parent shall be entitled to exercise its Cable Parent Exclusion
Right from time to time in its sole discretion. In the event that the number of
Specified Brands excluded by a Cable Parent exceeds its Exclusion Limit, then
the Cable Parent Premium Service Revenue Split shall be subject to adjustment as
provided below. The exercise of the Cable Parent Exclusion Right with respect to
a Specified Brand will be counted toward the Exclusion Limit regardless of

                                     -28-
<PAGE>
 
whether such Cable Parent exercises the exclusion right with respect to some or
all of its Affiliated Operators or with respect to some or all of the Specified
Promotions as to such Specified Brand. For purposes of the determination of
whether or not a Cable Parent has exceeded its Exclusion Limit, there shall not
be included as Specified Brands (i) a single Competitor Exclusion (as defined
below) or (ii) any exclusions which are Discretionary Exclusions (as defined
below). A "Competitor Exclusion" shall mean the exclusion of the Specified
           --------------------
Promotion(s) as to a single Specified Brand provider or service which is a
competitor to a content provider or service which is an affiliate of such Cable
Parent; provided, that, if Comcast Cable elects to use its Competitor Exclusion
        --------  ----
with respect to Specified Promotions of the Home Shopping Network, Inc. ("HSN"),
                                                                          ---
such exclusion shall be deemed to apply to all electronic retailing businesses
of HSN without regard to brand name. A "Discretionary Exclusion" shall mean a
                                        -----------------------
exclusion based upon (i) such Cable Parent's good faith determination that the
content to be offered constitutes pornographic or other immoral or overly
violent subject matter, (ii) such Cable Parent's reasonable determination that
the content to be offered may adversely impact an Affiliated Operator's
franchise to deliver cable television service and/or the @Home Service or (iii)
such Cable Parent's good faith determination that such promotions may relate to
promotions in respect of any Person providing Video Services.

(e)  The "Exclusion Limit" of each Cable Parent shall be three Specified Brands,
          ---------------                                                       
which Specified Brands may be changed by the applicable Cable Parent at any time
upon reasonable advance notice to @Home. In the event a Cable Parent exceeds its
Exclusion Limit, then during the monthly billing period in which such Cable
Parent has exceeded its Exclusion Limit the Premium Service Revenue Split (as
defined in the LCO Agreement) between the Operators that are Controlled
Affiliates of such Cable Parent and @Home shall be adjusted to (x) decrease the
Premium Service Revenue Split to such Operators and (y) increase the Premium
Service Revenue Split to @Home from such Affiliated Operators in accordance with
the following schedule:

15.  EXECUTION OF .COM AGREEMENTS AND EXERCISE OF CABLE PARENT ACCESS BLOCKING
RIGHT.

                                     -30-
<PAGE>
 
(a)  Each .Com Agreement and Promotional Agreement shall provide that the
content provider's right to connectivity over the @Home Service to subscribers
of any Affiliated Operators shall be subject to the exercise of the Cable Parent
Access Blocking Right and to @Home's obligations with respect to the @Home
Exclusivity Provisions. Upon execution of a .Com Agreement, @Home or any Cable
Parent or Controlled Affiliate acting as a sales agent on behalf of @Home, shall
provide written notice thereof by fax or e-mail to a designated contact person
at @Home and each other Cable Parent, as applicable. Such written notice shall
include (i) the identity of the content provider and (ii) a description
outlining in reasonable detail the content to be offered by such provider. Upon
exercise of its Cable Parent Access Blocking Right, such Cable Parent shall
deliver reasonable notice of its exercise of such right to @Home and the other
Cable Parents which will become effective within a reasonable period of time
after such notice. Subject to the other terms of this section, such Cable Parent
shall thereafter have the right to block the access by its subscribers of the
@Home Service to (1) any content offering with respect to which such Cable
Parent would have been entitled to exercise its Cable Parent Exclusion Right as
a Discretionary Exclusion (a "Discretionary Access Exclusion") and (2) any
                              ------------------------------
content provider which is attempting to provide Video Services exceeding the
duration limit set forth in the Specifications and Standards; provided, however,
                                                              --------  -------
that the Cable Parent's election to exercise its rights pursuant to this clause
(ii) shall not affect @Home's obligations pursuant to Section 7(a). Subject to
the next sentence, the exercise of the Cable Parent Access Blocking Right shall
be the sole responsibility of the Cable Parent so exercising it (including, but
not limited to, the determination of the technological means to block such
access), and each Cable Parent agrees that its exercise of such blocking right
will be done in such a way that it does not otherwise interfere in any
significant way with the delivery and presentation of the @Home Service. @Home
shall use its reasonable best efforts to assist the Cable Parent in the exercise
of such Cable Parent Access Blocking Right.

(b)  Each Cable Parent agrees to indemnify and hold @Home and each other
Stockholder harmless from all damages, costs and expenses (including reasonable
legal fees) incurred by @Home or each other Stockholder as a result of any
claims, actions, suits or other proceedings (including investigations related
thereto) of any third party or governmental or regulatory entity (other than a
party to a .Com Agreement or a Promotional Agreement) arising out of or relating
to the exercise by such Cable Parent of the Cable Parent Access Blocking Right
with respect to a Discretionary Access Exclusion.

(c)  @Home acknowledges and agrees that each .Com Agreement and each Promotional
Agreement entered into following the Execution Date will contain a provision in
which each content provider acknowledges and agrees to the existence and
exercise of such Cable Parent Access Blocking Right and Cable Parent Exclusion
Right and enforcement of the @Home Exclusivity Provisions, and agrees that such
content provider will not sue or threaten to sue, or seek or attempt to cause
any person to commence or threaten any governmental or regulatory action or
investigation against @Home or any Cable Parent as a result of or in connection
with the exercise of the Cable Parent Access Blocking Right or Cable Parent
Exclusion Right or the enforcement of the @Home Exclusivity Provisions.

16.  CONTENT TAG-ALONG RIGHT.

(a)  Each Parent agrees that neither it nor any of its Controlled Affiliates
will obtain any Additional Benefit (as defined below) unless it has complied
with the provisions of this section. In the event that any Parent or its
Controlled Affiliate seeks to enter into a transaction with a third party in
which such Parent or Controlled Affiliate may or will receive any Additional
Benefit as a condition of or as a result of such third party's entering into a
transaction with @Home, then such Parent or Controlled Affiliate will provide
written notice to each Cable Parent thereof describing such transaction and the
Additional Benefit to be received by such Parent or Controlled Affiliate. Such
written notice shall also constitute an offer by such Parent (the "Offeror") to
                                                                   -------
each Cable Parent (each, an "Offeree") to participate in such transaction upon
                             -------
the same terms and conditions as the Offeror (which, in the event any such
Additional Benefit is of a limited amount or type, shall mean the right to
participate in such transaction pro rata based upon each such accepting
Offeree's ownership of equity securities of @Home and otherwise upon the same
terms and conditions as such Offeror), which offer may be accepted by such
Offeree by written notice to such Offeror, each other Offeree and @Home
delivered to such persons not later than the twentieth business day following
the date of receipt of such notice; provided that the Offeror may require an
earlier response (but not less than five business days following the receipt of
such notice) by so specifying in the written notice to the extent such earlier
response is reasonably necessary.

(b)  In the event that it is not reasonably practicable to offer participation
in the Additional Benefit as described above, the Offeror shall promptly make
payments in cash to the Offerees so that the Offeror and Offeree share in the
value of the Additional Benefit pro rata based solely upon their respective
ownership of equity securities of @Home.

(c)  In the event that the consideration to be paid (or Additional Benefit to be
received) by any Offeror in connection with such transaction is to consist of
assets, securities or other property or services, then the price at which any
Offeree may accept such offer shall be or, if applicable, the amount of cash
payments by the Offeror, the fair market value of such assets, securities,
property or services, which if the parties are unable to agree, shall be the
appraised value thereof as determined by a mutually agreed upon investment
banking firm. The term "Additional Benefit" shall mean (i) securities or
                        ------------------
options, warrants or rights to acquire securities, (ii) assets or (iii) other
property or benefits of any type, in each case to be received by a Parent or a
Controlled Affiliate thereof in a transaction between such Parent or Controlled
Affiliate and such third party which transaction is conditioned upon or
otherwise contingent upon such third party's entering into such transaction with
@Home and is upon terms and conditions which are less favorable to @Home than
@Home's regular charges or other terms for such services, or is otherwise on
terms which are not arm's-length.

(d)  The exercise of any rights by a Cable Parent under this section shall be in
addition to any rights that a Cable Parent may have with respect to the
applicable transaction pursuant to Section 9 of this MDA Term Sheet.

(e)  The right to participate set forth in this Section 16 is hereinafter
referred to as the

                                     -32-

the "Content Tag-Along Right." 
     -----------------------

17.  PARENT UNDERTAKING.

(a)  Each of: (i)  TCI, as to TCIC, TCI. NET and TCI Internet Services; (ii)
CEI, as to CCI; and (iii) Comcast, as to Comcast Cable, hereby undertakes that,
in the event that such Parent entity acquires control of any cable television
systems which are not Controlled Affiliates of the applicable Cable Parent, such
Parent will cause such cable television systems to comply with the terms of this
agreement, including the Cable Parent Exclusivity Provisions, as if such cable
television systems were parties hereto; provided, that such Parent shall not be
obligated to terminate (other than in accordance with the terms and provisions
of the applicable agreement) the distribution of any residential Internet
Services distributed by such cable system prior to such time as the applicable
agreement expires or otherwise may be terminated by such Parent without the
incurrence of any material liability or additional obligations thereunder.

(b)  @Home hereby undertakes that, while the @Home Exclusivity Provisions are in
effect, in the event it provides Internet Services (or any comparable services
with comparable capabilities) at bit rate speeds greater than 128 kbps through
arrangements with an alternate distribution provider (an "Alternative
                                                          -----------
Arrangement") to residences in a geographic area in which a Cable Parent or its
- -----------
Controlled Affiliate subsequently acquires a cable television system that is
capable of distributing such services in the geographic area, @Home will use
commercially reasonable efforts (i) to offer such services through such cable
television system when such system is upgraded in accordance with the
Specifications and Standards and scheduled for commencement of service on the
Master Roll-Out Schedule and (ii) to terminate @Home's obligations under such
Alternative Arrangements in such geographic area; provided, that @Home shall not
be obligated to terminate (other than in accordance with the terms and
provisions of the applicable agreement) the distribution of such services under
such Alternative Arrangements in such geographic area prior to such time as the
applicable agreement expires or otherwise may be terminated by @Home (i) without
the incurrence of any material liability or additional obligations thereunder
and (ii) without any material adverse impact on the economics to @Home of
providing such services to residences in the geographic area.

18.  OTHER SERVICES.

(a)  Any broadband local transport services provided by Operator to @Home as
part of the @Home Facilities, including connectivity to content providers, will
be the subject of a separate agreement between the parties, the terms and
provisions of which (including the compensation payable thereunder to Operator)
shall be mutually agreeable to the parties.

(b)  [RESERVED]

(c)  To the extent that any Eligible Cable Parent so requests in connection with
     such Eligible Cable Parent=s provision to its subscribers of any Excluded
     Service, @Home agrees to make available to such Eligible Cable Parent and
     its Controlled Affiliates to the extent required to deliver such Excluded
     Service to the subscribers of such Eligible Cable Parent (i) use of 

                                     -33-

@Home's Internet Backbone and related network management services (including the
NOC) upon then current market rates and terms (subject to the MFN Provisions),
(ii) use of @Home's provisioning services on a Cost-Plus Basis, and (iii) use of
the @Home Facilities (not including servers) located at the headends of such
Cable Parent's cable television systems on a Cost-Plus Basis that are necessary
or convenient to route any IP traffic related to such Excluded Service. @Home
will determine in good faith the appropriate method for implementing these
services and will consult and cooperate with the applicable Cable Parent in
connection with the foregoing.

(d)  @Home agrees that it will keep accurate books and records and will provide
each of the Cable Parents with access to such books and records, upon reasonable
notice and at reasonable times, and shall use reasonable efforts to cooperate
with each Cable Parent in connection with an examination of such books and
records for purposes of determining @Home's Cost and calculating the matters
contemplated by the definition of the term "Cost-Plus Basis".

19.  AMENDMENTS TO THIS MDA TERM SHEET.

The provisions of this MDA Term Sheet may not be amended, modified, supplemented
or superceded unless approved in writing by each Stockholder and @Home.

20.  SPECIFIC PERFORMANCE.

Without intending to limit the remedies available to any of the parties hereto,
each of @Home and each Cable Parent acknowledges and agrees that a breach by
such party of any provision of Sections 5, 7, 9, 13, 15, 17 and 18 of this MDA
Term Sheet will cause the other parties irreparable injury for which an adequate
remedy at law is not available.  Therefore, the parties hereto agree that in the
event of any such breach each such party shall be entitled to an injunction,
restraining order or other form of equitable relief from any court of competent
jurisdiction restraining any other party hereto from committing any breach or
threatened breach of, or otherwise to specifically enforce, any such provision
of this Agreement, in addition to any other remedies that such parties may have
at law or in equity.

21.  TERM OF MDA TERM SHEET.

This MDA Term Sheet or any definitive agreement superceding this MDA Term Sheet
shall terminate as to each Cable Parent at the end of the Term of the last to
terminate of the LCO Agreements in effect between @Home and such Cable Parent or
its Controlled Affiliates entered into pursuant to this MDA Term Sheet or any
definitive agreement superceding the provisions of this MDA Term Sheet
(including any extension or renewal thereof).

<PAGE>
 
(d)  GENERAL MATTERS:

     This Exhibit B is intended to set forth the terms and conditions of the
     definitive LCO Agreements to be entered into between @Home and the
     Affiliated Operators of the Cable Parents pursuant to which such Affiliated
     Operators would distribute the @Home Services.  These provisions are also
     intended to serve as the basis upon which @Home would seek to negotiate
     definitive LCO Agreements with Operators which are not Controlled
     Affiliates of any Cable Parent.  With respect to definitive LCO Agreements
     between @Home and such Affiliated Operators, the following provisions are
     intended to provide a summary of the terms and conditions of such
     definitive LCO Agreements. With respect to definitive LCO Agreements to be
     entered into with Operators which are not Controlled Affiliates of any
     Cable Parent, however, such terms and conditions are intended to form a
     basis upon which @Home may negotiate such definitive agreements, and
     therefore, subject to the MFN provisions of the Master Distribution
     Agreement (which are currently set forth in Section 9 of the Master
     Distribution Agreement Term Sheet), @Home may vary such terms and
     conditions granted to such Operators from the terms and conditions set
     forth below.


2.     ROLL-OUT OF THE @HOME SERVICES

(a)  OPERATOR TERRITORY:

     Each LCO Agreement entered into by @Home with an Operator will provide that
     the @Home Services initially will be made available as and to the extent
     provided in the Master Roll-Out Schedule (the relevant portions of which
     shall be incorporated into such LCO Agreement (such portion referred to
     below as the "Roll-Out Schedule")) in that portion of the geographic
                   ------------------                                     
     area covered by the LCO Agreement where Operator is providing cable
     television service through Operator's cable television distribution
     facilities (the "Operator Territory").
                      ------------------   

(B)  @HOME ROLL OUT COMMITMENT:

     @Home will use commercially reasonable efforts to complete the Network
     Upgrade in the Operator Territory containing the Offered Homes Passed
     covered by the LCO Agreement on or before the applicable Projected
     Commencement Date, in accordance with the applicable provisions of the
     Roll-Out Schedule (and thereafter as may be required to make available to
     Operator the @Home Services as of such Projected Commencement Date
     (including at any additional applicable Point of Demarcation) in connection
     with the commencement of the provision of the @Home Services to subscribers
     in additional portion(s) of the Operator Territory), in each case subject
     to the Operator having completed the Cable System Upgrade in the applicable
     portion(s) of the Operator Territory. Subject to the requirements of the
     Roll-Out Schedule, @Home and Operator shall negotiate in good faith and use
     commercially reasonable efforts to coordinate the timing of the completion
     of the Cable System Upgrade and the Network Upgrade in each applicable
     portion of the Operator Territory.

(c)  FAILURE BY @HOME TO COMPLETE NETWORK UPGRADE:

     In the event that @Home does not complete the Network Upgrade in the
     Operator Territory on or prior to the date which is 120 days after the
     Projected Commencement Date, then, Operator shall have the right to
     terminate the Cable Parent Exclusivity Provisions as to the Operator
     Territory.

     In the event that @Home does not complete the Network Upgrade in the
     Operator Territory on or prior to the date which is 180 days after the

                                      -2-
<PAGE>
 
     Projected Commencement Date, then, Operator shall have the right to either
     (x) continue the election made above and, at such time as the @Home
     Services become available for distribution in such area, distribute the
     @Home Services in accordance with the terms of the LCO Agreement (other
     than the Cable Parent Exclusivity Provisions as to the Operator Territory)
     or (y) terminate the LCO Agreement; provided however, that if Operator
                                         -------- -------                  
     terminates the LCO Agreement and @Home completes the Network Upgrade in the
     Operator Territory within the otherwise applicable Term (as defined below)
     of such LCO Agreement (assuming for such purposes that such LCO Agreement
     had not been terminated), Operator may then elect to reinstate the LCO
     Agreement (without, however, giving effect to the Cable Parent Exclusivity
     Provisions as to the Operator Territory).

     In the event that @Home fails to complete the Network Upgrade as of the
     applicable Projected Commencement Date with respect to any portion of the
     Operator Territory, then Operator's remedies described above will only be
     exercisable with respect to such portion of the Operator Territory, unless
     such failure relates to a material portion of the Operator Territory, in
     which case such remedies shall apply to the entire Operator Territory.

     The availability of the remedies to Operator set forth above with respect
     to any failure by @Home to complete any portion of the Network Upgrade as
     to any portion of the Operator Territory shall be subject to Operator's
     completion of the Cable System Upgrade.

(d)  OPERATOR ROLL-OUT COMMITMENT:

     Operator will use commercially reasonable efforts to complete the Cable
     System Upgrade of the required Operator Facilities in the Operator
     Territory no later than the applicable Projected Commencement Date, such
     that the number of Homes Passed in the Operator Territory capable of
     receiving the @Home Services equals or exceeds the number of Homes Passed
     specified in the Roll-Out Schedule for the applicable Planning Period,
     subject to @Home having completed the Network Upgrade in the applicable
     portions of the Operator Territory.  Notwithstanding any other provisions
     of this Exhibit B, upon not less than 180 days notice prior to the
     Projected Commencement Date, an Operator may terminate or defer the
     Projected Commencement Date as to all or any portion of the Operator
     Territory without any liability hereunder, in which event (in the case of a
     termination or deferral affecting the entire Operator Territory by an
     Affiliated Operator) Operator shall have the rights described in the Master
     Distribution Agreement (currently set forth in Section 11 of the Master
     Distribution Agreement Term Sheet), but subject to the terms and conditions
     described therein,  to substitute one or more cable systems for those in
     the Operator Territory or portion thereof on the Master Roll-Out Schedule
     and to require @Home to enter into an LCO Agreement with respect to the
     Operator Territory served by such substitute cable systems (in which case
     such substitute cable systems shall retain the same roll-out priority and
     Projected Commencement Date as the cable systems they replaced).  Operator
     may not terminate or defer the Projected Commencement Date as to less than
     all of the Operator Territory unless the remaining portion of the Operator
     Territory (as to which the Projected Commencement Date has not been so
     terminated or deferred) represents a substantial portion of the Operator
     Territory (in terms of the number of Homes Passed in the Operator
     Territory).  In the case of any such deferral of the Projected Commencement
     Date, Operator=s rights with respect to a failure by @Home to complete the
     applicable Network Upgrade shall apply with respect to such deferred
     Projected Commencement Date.

                                      -3-
<PAGE>
 
(e)  FAILURE BY OPERATOR TO ROLL-OUT:

     Subject to the right to terminate or defer the Projected Commencement Date
     set forth in the preceding paragraph, in the event that Operator does not
     complete the Cable System Upgrade of the required Operator Facilities on or
     prior to the date which is 180 days after the Projected Commencement Date
     set forth on the Roll-Out Schedule in any material respect, then (i)
     Operator shall be required to pay to @Home, as liquidated damages and not
     as a penalty, the @Home Specified Remedy and (ii) @Home shall be entitled
     to terminate its obligations under the @Home Exclusivity Provisions with
     respect to those portions of the Operator Territory where @Home reasonably
     determines, after consultation with Operator, that Operator has ceased to
     use commercially reasonable efforts to complete the Cable System Upgrade so
     as to comply with the LCO Agreement and the Roll-Out Schedule.

     To the extent that any failure by Operator to complete a Cable System
     Upgrade results from the failure by Operator to timely obtain any
     regulatory or third party consent or approval required on the part of
     Operator in order to so complete the Cable System Upgrade or to  distribute
     the @Home Services in any portion of the Operator Territory, the
     obligations of each party under the LCO Agreement shall be suspended until
     such time as Operator obtains any such regulatory or third party consent or
     approval; provided, that Operator shall continue to use all commercially
     reasonable efforts to obtain any such consent or approval; and provided
     further, that (i) the obligations of @Home under the @Home Exclusivity
     Provisions with respect to any affected portion(s) of the Operator
     Territory shall terminate to the extent any such suspension lasts for more
     than 180 days after the Projected Commencement Date and (ii) either party
     shall be entitled to terminate the LCO Agreement as to the affected
     portion(s) of the Operator Territory in the event of any such suspension

                                      -6-
<PAGE>
 
     calculated on a Cost-Plus Basis).


4.   COMPENSATION AND BILLING.

(a)  ALLOCATION OF BILLING RESPONSIBILITY:

     Operator shall be responsible for the billing and collection of monthly
     subscription fees (including the allocable portion of any charges related
     to bundled services) from subscribers to the @Home Services in the Operator
     Territory which receive the @Home Services through the Operator Facilities.
     Notwithstanding the foregoing, as between @Home and Operator, unless
     otherwise agreed, the collection of Premium Service Revenues shall be the
     responsibility of the party contracting with the applicable provider of
     such services regarding the provision of such services (and, as between
     @Home and Operator, such contracting party shall have complete discretion
     as to the pricing of such services to subscribers).

(b)  PRICING:

     Subject to the parenthetical in the last sentence of (a) above, Operator
     shall have complete discretion as to the pricing of the @Home Services to
     subscribers in the Operator Territory receiving the @Home Services through
     the Operator Facilities.

(c)  COMPENSATION:

     Operator shall make monthly payments (the "Monthly Payments") to @Home in
                                                ----------------              
     respect of each month during the Term in an amount equal to (i) 35% of
     aggregate Basic Service Revenues (as defined below) collected by Operator
     during such month from the provision of the @Home Services to subscribers
     using the Operator Facilities (the "Basic Service Revenue Split") plus (ii)
                                         ---------------------------            
     35% of Premium Service Revenues (as defined below) collected by Operator
     during such month with respect to subscribers accessing such services using
     the Operator Facilities (to the extent that Operator is responsible for the
     collection of such charges).  Attachment A sets forth the services @Home
     shall provide to the Operator in return for the Basic Service Revenue
     Split.

     The Basic Service Revenue Split is based on the assumption that Operator
     will provide Tier I Customer Service and that @Home will provide Tier II
     Customer Service and Tier III Customer Service (as such terms are defined
     in Attachment B).  To the extent that Operator directs @Home to provide all
     or any portion of Tier I Customer Service, @Home will be entitled to
     compensation from Operator for the provision of such services on a Cost-
     Plus Basis.  In the event that Operator elects to perform all or part of
     Tier II Customer Service, such Operator will receive a credit against the
     amount it would otherwise owe to @Home pursuant to this paragraph
     calculated on a Cost-Plus Basis.

     @Home shall make payments to Operator on a monthly basis in an amount equal
     to 65% of Premium Service Revenues collected by @Home during such month
     with respect to subscribers in the Operator Territory accessing such
     services using the Operator Facilities (to the extent that @Home is
     responsible for the collection of such charges).

     The percentage of Premium Service Revenues to which Operator is entitled
     pursuant to the preceding three paragraphs is referred to herein as the
     "Premium Service Revenue Split."  The Premium Service Revenue Split will be
     ------------------------------                                             
     subject to adjustment in accordance with the provisions of the Master
     Distribution Agreement currently set forth in the Master Distribution
     Agreement Term Sheet under the caption "Execution of Promotional 

                                      -7-
<PAGE>
 
     Agreements and Exercise of Cable Parent Exclusion Right."

     As used herein, "Basic Service Revenues" means revenues from the @Home
                      ----------------------                               
     Services collected by Operator (other than Premium Service Revenues)
     including any amounts received by Operator in respect of the provision of
     cable modems to subscribers (other than any such amounts received from the
     sale of cable modems to subscribers) but excluding any fees collected for
     installation, and "Premium Service Revenues" means the net revenues
                        ------------------------                        
     retained by Operator or @Home, as the case may be (but prior to any
     payments to the other pursuant to the Premium Service Revenue Split),
     derived from its performance pursuant to .Com Agreements and Promotional
     Agreements, including service fees, content provider charges, transaction
     fees, subscriber fees, advertising and promotional revenue or other
     transaction value (including barter payments or advertising avails), from
     the provision of the @Home Services to customers in the Operator Territory
     through the use of the Operator Facilities.

     Notwithstanding the foregoing, any fees or other amounts received by @Home
     which relate to the programming of the National Area, including service
     fees, content provider charges, transaction fees, advertising and
     promotional revenue or other transaction value (including barter payments
     or advertising avails) shall not be included within the definition of
     either Basic Service Revenues or Premium Service Revenues, and @Home shall
     be entitled to retain all amounts collected by it in respect of such
     activities.

     The foregoing Basic Service Revenue Split and Premium Service Revenue Split
     (collectively the "Revenue Splits") to @Home may be increased by a Required
                        --------------                                          
     Either E Cable Parent Election (but only with respect to all existing LCO
     Agreements with an Affiliated Operator and all LCO Agreements to be entered
     into with an Affiliated Operator).  For purposes of the LCO Agreement, a
     "Required Either E Cable Parent Election" shall mean a written election
     providing for an increase in either or both of the Revenue Splits to @Home
     signed by at least two-thirds (66-2/3%) in number of the Either E Cable
     Parents (rounded up to the nearest whole number) (where an AEither E Cable
     Parent@ is a Cable Parent whose Stockholder Group contains either an
     Eligible Stockholder or an Exclusive Stockholder); provided, that (i) such
     election must be signed by a Cable Parent that is a Controlled Affiliate of
     TCI to the extent that the TCI Stockholder Group contains an Either E Cable
     Parent and (ii) in the event that there are fewer than two Either E Cable
     Parents that are not Controlled Affiliates of TCI, such election must be
     signed by each Either E Cable Parent.

     Notwithstanding the foregoing, any fees or other amounts received by
     Operator which relate to the programming of the Local Area or the provision
     of a Local Service, including service fees, content provider charges,
     transaction fees, advertising and promotional revenue or other transaction
     value (including advertising avails and barter payments) shall not be
     included within the definition of either Basic Service Revenues or Premium
     Service Revenues, and Operator shall be entitled to retain all amounts
     collected by it in respect of such activities; provided, that @Home shall
     be entitled to compensation on a Cost-Plus Basis for network management
     services provided by @Home and any caching and replicating (including, but
     not limited to, technical assistance and, if applicable, the lease of
     capacity on the @Home Facilities) provided by @Home with respect to such
     programming of the Local Area or with respect to such Local Service in
     connection with the provision of such Local Service and/or the connection
     of such Local Content provider to the @Home Network for such services
     requested by Operator.

     basis for such calculation, which calculation shall have been certified by
     an officer or authorized designee of Operator as true and correct and as

     calculation shall have been certified by an officer or authorized designee
     of @Home as true and correct and as having been made in accordance with the
     applicable provisions of the LCO Agreement.  Not later than 30 days after
     the last day of each month @Home shall deliver to Operator Operator's share
     of such Premium Service Revenues in respect of such month.  @Home shall

     schedule of fees.  @Home shall bill Operator on a regular basis for such
     optional services elected by Operator, and Operator shall remit such
